Definitions

the invention relates to a method for wrapping in particular sharp-edged, in particular multi-part General cargo units, especially cuboid or cube-shaped stacks of general cargo, which, for example, consist of (i.a. or the like stacked on a pallet) consist of plastic (such as especially polyethylene) existing stretch film, which is a fully wrapped unit load in each case at least on their (generally four) side surfaces under it by cross-stretching inner horizontal circumferential tension completely wrapped, preferably (especially with the film in addition to the horizontal during the covering over the piece goods unit to be wrapped in each case Cross stretch embossed vertical longitudinal stretch) on its underside (from its Edges) with a so-called "understretch” at least partially covered, and thus possibly also at least partially envelops the underside of the piece goods unit, and which the piece goods unit in the case of a hood-shaped formation of the stretch film covering, also on its upper side completely covered, as is always the case when a general cargo stack due to the stretch film wrapping not only one
the height of the (multifunction) elements for different stack heights be constant and absolutely relative (to the stack height) low, e.g. only approx. 20 cm or 30 cm, although the height of the stack of piece goods to be wrapped is, for example, 180 cm.
either the cross-welding process stops closed hood base ("hood cover”) or one over the multifunction elements after hitting according to plan upward projecting edge portion of the tubular Wrapping hose section to the top of the unit, and can support this in the manner of an abutment, so that the stitched onto the multifunction elements Film when lowering the i.a. on a common lifting frame arranged multifunctional element successively derived from them, and under (i.a. considerable) circumferential stretch ("transverse stretch”) and complete covering of the side surfaces of the general cargo unit to the general cargo unit, i.a. so that this at the edge portions of its underside from the lower end portion of the wrapping tube portion is undershot with a so-called understretch.

This understretch is in the finished Wrapping condition may not be complete over the bottom of the on its side surfaces encased unit load unit (if necessary, one arranged under the unit load parts of a unit load stack Palette) i.w. vertically downwards, but lies down due to the embossed on it too Circumferential expansion i.w. (horizontally) flat on the peripheral edge section of the underside the general cargo unit.
the present invention further relates to a device for wrapping esp. sharp-edged piece goods units of the type already mentioned for carrying out the aforementioned method, with a feed device, by means of which to encase a a piece of tubing predetermined to the device supplied to the unit Length of the piece goods unit to be wrapped (generally / preferably from a rewound one Hose supply) is to be supplied, and with several (generally four) expedient arranged on a common lifting frame, preferably bow-shaped Multifunctional elements for performing several functions, namely for recording and (i.w. unexpanded) spreading of the supplied free hose end section, and as abutment on impact (using reef rollers) in i.w.
a feed device by means of which to encase a a piece of tubing predetermined to the device supplied to the unit Length of the piece goods unit to be wrapped (generally / preferably from a rewound one Hose supply) is to be supplied, and with several (generally four) expedi
the device is still with a cutting device for the respective severing of a (wrapping) hose section Provide a predetermined length from the hose supply, if necessary one Welding device, by means of which the hose section for the purpose of forming a hood the separation with a predetermined distance to its free end with a transverse seam is, and each with a multifunction element associated reefing devices each with a reefing element that can be driven relative to the respective multifunctional element like a reef roller, by means of which the foil can be reefed onto the multifunction elements and with a control device that controls the casing (and possibly the hood formation).
the present invention relates to a loading unit, as is the case with the method the genus described above - preferably using the above in their essential elements described device - is to be produced / is obtained.
stretch film packaging technology due to "critical points” such as sharp edges and / or pointed Corners on the top and / or bottom and / or appropriately trained projections the side walls of packaged items to be packaged arises from the fact that it is on such critical points of general cargo units to be covered with stretch film (e.g. / especially the Stack top edges and the upper corners of, for example, brick piles or the like) at their Contact with the one that has slipped from the multifunctional elements, i.a. under a substantial Peripheral tension (or even a biaxial tension that places even greater stress on the film) standing film for a punctiform penetration or a linear incision the relatively thin plastic film, which is under considerable tension can.
critical points such as sharp edges and / or pointed Corners on the top and / or bottom and / or appropriately trained projections the side walls of packaged items to be packaged arises from the fact that it is on such critical points of general cargo units to be covered with stretch film (e.g. / especially the Stack top edges and the upper corners of, for
the present invention is therefore based on the object of the method of the above described genus and the device for carrying out described above that process (and thus last but not least using that process or use loading devices to be manufactured) in both technical and economic terms satisfactorily to improve, in particular, that general cargo units with "critical points” in the sense of the above statements such as sharp edges and / or pointed corners - especially in the area of an abutment for covering the multifunctional elements peelable film forming the top of the general cargo unit -, or other points that protrude pointedly or with sharp edges can be encased perfectly without that there is damage to the film.

second hose section hose section
first Hose section under which in the following, if necessary, a film hood formed from it should be understood
each serves to envelop general cargo unit (for example, in the case of fairly uniform, square-shaped Stack of bricks, as with a good palletizer, on a flat pallet are to be formed, possibly only for the sharp-edged peripheral top edge of the stone stack with its four corners), so that it is completely for reinforcement of this "critical point" is sufficient if such a unit load unit on both sides of its peripheral upper edge (ie on the one hand on their four side surfaces, and on the other hand on their top side) with one in relation is provided with a relatively narrow, annular film section relative to the stack height, which (and if necessary even preferred) also multi-layer (at least two layers) can be.
general cargo unit for example, in the case of fairly uniform, square-shaped Stack of bricks, as with a good palletizer, on a flat pallet are to be formed, possibly only for the sharp-edged peripheral top edge of the stone stack with its four corners
a second hose section can of course be attached to the general cargo unit also extend further down, or it can save film material if necessary, two or more single or multi-layer reinforcement hose sections with mutual distance can be arranged on a piece goods unit, with several critical Make sure that it is clear that you are covering several singular reinforcement hose sections required process steps the throughput of the Packaging machine would not possibly reduce so much that it would be more economical and therefore Ultimately, it is also technically more sensible to lengthen the second hose section like that to dimension the first hose section, or instead a sheathing hose section to choose with increased film thickness, and if necessary on the application of the present To renounce invention. Such problem cases are the exception. On the other hand cases with only one "critical point" occur relatively frequently, so that the present Invention opened up a large field of application.
Such a configuration is loading unit (at least i.w.) lying against the piece goods unit unstretched not to be regarded as optimal from several points of view.
each or each reinforcement hose section - be it now one or more layers - also by means of the multifunctional elements on the general cargo unit is arranged as regards this after the attachment of the foil reinforcement of the wrapping hose section or a hood made from it in a known manner Way is the case.
a method variant according to the invention in which one at a critical point the ring-shaped reinforcement hose section to be attached to the piece goods unit to be wrapped is applied in two layers (or possibly even three or more layers), however consists of a one-piece hose section.
the taken hose section by the multifunction elements in turn in itself known way with the hose end portion they picked up by diagonal Spread apart (generally unstretched) and it becomes a tube section given length in i.w. concentric to the longitudinal axis of the hose or general cargo running wrinkles on the multifunction elements.
the reinforcement hose section becomes at a distance from the free Separate the hose end in the specified length from the hose supply, and if necessary so re-referenced to the multifunctional elements (i.e. re-added), or if necessary using the reverses the reefing rollers driven to the reefing process as far from the multifunction elements reefft (i.e. released upwards) that the upper free edge of the rest on the multifunctional elements of reinforced reinforcement hose section by a predetermined Dimension protrudes above the upper end of the multifunction elements.
the reinforcement hose section is to be at a distance from the top of the piece goods unit (only) attached over a (height) section of the general cargo side walls (e.g. Fig. 21), or at the lower end section of the piece goods unit and partially under it (see e.g. Fig.
the one above the multifunctional elements must protrude freely Edge section of the reinforcement hose section to be smaller so that it during the pulling process sliding under sliding friction on the unit load unit until the height position is reached is in which the free film edge portion firmly on the side surfaces of the unit load put on, or - like the bottom stretch of a wrapping hose section - in the edge area should firmly attach to the underside of the general cargo unit, like this below Embodiments will be explained further.
the multifunction elements from this first lower working position With further sliding of film material, which is the outer second Reinforcement layer on the first one already on the side walls of the general cargo unit Reinforcement layer - raised to a (higher) second lower working position, in which they have completely released the reinforcement hose section, which is originally lower end section under the circumferential stretch impressed on the hose material as an (upper) second upper stretch layer on the edge section of the general cargo top stored (lower) first upper stretch layer.
the multifunction elements are moved upwards together to their starting position, around a wrapping hose section (generally as a film hood) to be taken up from the hose supply, spread open, kept reefed, in the pull-over position crosswise, and finally pull over the piece goods unit to be wrapped.
a wrapping hose section generally as a film hood
the multifunctional elements are immediately in the / a lower working position proceed in which the reinforcement hose section has completely slid off them, and lies in one layer on the piece goods unit, and from this lower working position immediately move to its upper starting position to complete the actual wrapping process with the wrapping hose section (possibly designed as a hood) and perform.
the reversible reefing rollers - if in between from the multifunction elements to the outside in a rest position are - again from the outside to the multifunctional elements with the ones they have torn up Slide up film, and in the sense of a hit in the opposite direction to the (Open) reefing driven until it peels off as much film from the multifunction elements have that they appear as (one-piece) second and third upper stretch layer when lowering again of the multifunctional elements have been placed firmly on the first upper stretch layer, and below Friction of the second upper stretch layer to the first upper stretch layer and the third upper stretch layer form an abutment to the second upper stretch layer, against which at If the multifunction elements are lowered again, slide further film away from them and as a third reinforcement layer from the outside firmly to the already existing second reinforcement layer of the reinforcement hose section on the side walls of the general cargo unit can put on.
the multifunctional elements become in the first lower working position or, if necessary, a slightly lower lower working position lowered until the film has completely slipped off the multifunction elements, and they can be moved back to their starting position.
this process is analogous repeated until in the second lower working position or in the first lower working position or a lower working position that is even lower than this the annular hose material of the reinforcement hose section completely from the Multifunctional elements has slipped, and then immediately back into their upper Starting position can be used to make the actual wrapping process in conventional Way to perform.
the controller is designed so that at the beginning of a packaging cycle, first a in the fully encased loading unit as Foil reinforcement or reinforcing hose section serving as tear protection from the Multifunctional elements on the free end section of the hose supply (by retracting the approximated multifunctional elements in the pre-opened free hose end) and by moving the multifunctional elements diagonally apart I. W.
each bracket with in its central (apex) area a (foil conveyor) device is provided by means of which the Cross-stretched wrapping film in the pull-over position of the temples during the pull-on process above the - mostly by pinching the film - i.w. in the middle of the Retraction roller moved up and driven in the opposite direction to the direction of rotation when reefing can be moved controllably over the bar until it leaves the upper edge of the bar, and preferably free of sliding friction, as described below in various configurations is further explained.
the present invention is inter alia and especially the knowledge that when used the one already above and bracket described in more detail below as multifunctional elements in the implementation of the entire wrapping process on the one hand, it is necessary for the film to come up in the middle of the bracket when the film hits it Reef rollers should act on the temples with a vertical distance from the upper edge of the temple leave so that the foil picked up by the brackets (mostly without stretching) when it hits from the reef rollers (due to friction between reef roller and film) at the respective contact point between reef roller and film due to friction between reef roller and the (outside the) film is to impress a downward tensile force that is able to the film also downwards on the side bracket areas not acted on by the reefing roller to pull on / over the respective bracket.
the reef roles are instead adjacent to the upper temple edge or even in the area of the upper temple edge section when reefing the frame, the foil to be torn off is in the side area of the frame not impress a sufficiently large vertical tensile force (component), so that in the side bracket areas no problem can be achieved.
The may be - as stated - useful when hitting film on the bracket (especially the impact in the two temple side areas running laterally to the middle temple area is still supported by friction-reducing measures), however not helpful when pulling the film off the brackets during the pulling process. Because as soon as a film section the reef roll or the upper of the two abutment rolls left when pulling upwards, it gets above the upper abutment roller again inevitably (as already below the lower abutment roller) on the bracket below uncontrolled sliding friction, and must also the undercut area between the bead-shaped upper bracket edge section projecting outward toward the bracket support section overcome.
each bracket has a width that is at least as large (preferably somewhat larger) is like the width of the flat belt, as well as a height that is at least as big as that Thickness of the flat belt (preferably slightly larger) and the upper edge of the window-like Bow recess runs horizontally and is rounded down, it can form the lower deflection element for the flat belt (see also embodiment according to 2 and 3) without the bracket need to be provided with a roller assembly, the desired goal of a perfect meeting on the one hand and a perfect one On the other hand to achieve sliding of the film when covering.
Tensile forces on the film, which also in the side bracket areas to hit impress sufficient (friction) tensile forces, especially since the film still (at least i.w.) is not cross-stretched, and therefore not significantly outside of the reef role Pressure is applied to the flat belt, which - especially if it is pretensioned in the longitudinal direction - remains at rest because the friction between the inside of the flat belt and the Flat belt deflections at the upper edge of the frame and at the upper edge of the window-like Recess i.a. is significantly larger than between the reef roller and the film.
Such a cylindrical lower deflection element per bracket can in a further embodiment of the present invention as a roller rotatable about its longitudinal central axis (“lower roller”) be formed, but it can also be non-rotatable in another embodiment be arranged in the bracket (in its recess), so that it is basically has the same (deflection) function as in the embodiment described above, in which the flat belt on the rounded horizontal top edge of the window-like Recess is deflected.
such a configuration can also take on a further function, in particular when the cylindrical lower deflection element is not on it Longitudinal central axis is attached to the bracket support section, but each on an eccentric to its longitudinal central axis extending eccentric axis, and when doing so for the purpose of tension of the flat belt can be pivoted about its eccentric axis in the unlocked state, as well as in the selected clamping position can in turn be locked on the support section during operation.
a variant of the embodiment described above is that between the cylindrical lower deflecting element and the upper edge of the bracket around its longitudinal central axis rotatable abutment roller is arranged with a horizontal axis of rotation, to which the reefing role of the assigned reefing unit (when reefing and pulling off film from the brackets) is to be moved under pressure.
the upper edge section can in each case a bracket in the middle bracket area of a roll rotatable about its longitudinal central axis ("Top roller") be formed, the length of which is expediently at least as long as that Width of the reef roll.
This top roller therefore forms the upper flat belt deflection, the lower deflection can take place in the manner already described, preferably but by means of a lower role.
Bow roller can be designed as a reversibly drivable (small) drum motor, and regardless of whether with flat belt training or without (small) belt conveyor (and instead, a height-adjustable reefing roller) is used, but such a configuration is obviously much more complex, so that i.a. will refrain from doing so, especially since desired effects can also be achieved with considerably simpler means.
one of the Multi-function elements to handle hose section - be it a reinforcement hose section or a wrapping hose section - when hitting Tubular film on the multifunction elements i.a.
the resistance during the sliding process due to the generation of a vertical stretch underneath preferably provided in the pulling process of the upper edge section of each multifunctional element is consciously increased, but that on the other hand the bow-shaped multifunctional elements in the corner areas of the In the state of covering, the film is regularly heavily cross-stretched only over a fraction of the extend respective film side wall, and that each between two adjacent Multi-functional elements are therefore not in the film section during the covering is supported directly by the multifunction elements, but is freely tensioned. That has again the consequence that the film in these sections continues towards the inside / towards the center can contract as in the supported by the multifunctional elements (as an abutment) Corner areas, so that all these circumstances an effortless sliding of the film from the Completely complicate multifunction elements during covering. At least that's it then the case when the film in the particularly stressed corner areas below (Sliding) friction must slide off the bow-shaped multifunctional elements.
Multifunctional element a (double) roller arrangement consisting of two with a small mutual spacing of aligned rollers (same diameter), however, the upper roller is located at a considerable distance below the upper edge section of each multifunction element.
FIG. 1 shows a simplified partial top view of exemplary components of a Device for wrapping unit loads 1, namely cuboid or cube-shaped General cargo stacks with a square cross-section, with one made of plastic (e.g. / especially polyethylene) existing, hood-shaped stretch film wrapping 2, which wrapped a finished (Packaged) general cargo unit 1 on its four side surfaces below it by transverse expansion stamped inner circumferential tension completely wrapped around the unit 1 the underside of which underpins from the edges with a so-called understretch, and therefore also this is partially enveloped, and due to the hood-like design of the stretch film envelope also completely covers the top of the piece goods unit 1.

the device is designed with a gusseted tube (not shown)
Hose supply made of plastic stretch film provided in the flat folded Supply state is coiled up to a hose reel, from which in each case if necessary Tubular film is fed.
the device therefore has a (not shown) i.w. out Support and deflection rollers on existing feed device, by means of which each for wrapping a piece of unit 1 fed to the device, a hose section from Hose supply is withdrawn and fed to the piece goods unit 1 to be wrapped so that at the beginning of a packaging cycle, the free end section of the film tube above the hanging freely to each enveloping unit 1.
the film tube Since the hose material is folded flat in the state of storage, and the same "sticking" to adjacent hose layers due to adhesive forces, the film tube must first be suitably opened at its free end section so that it can then be picked up by recording elements and continue can be treated so that it is finally pulled as a hood over the unit 1 can be.
This pre-opening can, for example, by suction heads or the like. happen by are approached from the outside to the free hose end section, and / or e.g. by wedge-shaped, sword-like pre-opening elements in the feed movement path of the film tube and when pulling the hose over these elements ensure that that it is opened so far at least at its free end section that suitable receiving elements can be inserted into the free hose end.
bracket-shaped receiving elements (bracket) 3
multifunction elements are not just for recording of the free hose end section, for which it is in a diagonal to the longitudinal axis of symmetry collapsed recording state can be moved into the free hose end, but afterwards also for the expansion-free spreading of the free hose end section, whereby from its recording position (generally synchronous) horizontally into a Spread position be moved apart.
This spreading position also forms the reefing position of the bracket 3, in which Hose material in required length in i.w. concentric folds to the longitudinal axis of the hose is reefed by means of reefing rollers 7 on the brackets, which act as abutments and holding means serve.
This impact occurs through so-called reefing units 5, each of which has a bracket 3 are assigned a reversible at their end section facing the relevant bracket 3 have drivable reef roller 7, and from an external rest position so horizontally the stirrups 3 are to be moved up so that the reefing roller 7 is each under an adjustable pressure abuts on the outside of the bracket 3 assigned to it.
the reefing rollers 7 expediently have an elastic one Coat 7 '.
Fig. 1 shows in its middle part over one indicated by dash-dotted lines General cargo unit 1, the longitudinal center axis of which is designated by M, four such bow-shaped Multifunctional elements (bracket) 3 in their spread or reef position.
the brackets 3 are symmetrical to the longitudinal central axis in each working position M arranged, namely in their in Fig. 1 with solid lines Spread and Aufstellwolf each in a corner area of the one they recorded and unexpanded expanded film tube, which as a film hood 4 over each enveloping general cargo stack 1 is to be pulled. Because the film hood 4 is supposed to be finished Wrapping condition with considerable horizontal (circumferential) transverse expansion on the side surfaces of the stack 1, so that they are accordingly in the still unexpanded expansion state must have a correspondingly smaller scope than the stack 1.
All four reef units 5 are in this reef position with their reef roller 7 on the outside of the film tube / film hood 4, and this again with its inside on the outside of the respective bracket 3 Refrollen 7 driven in the direction of rotation indicated by an arrow 8, so is Hose material withdrawn from the hose supply and concentric with the longitudinal central axis M running folds up on the bracket 3.
the investment site is located here each reef roller 7 at a distance f below the upper edge of the bracket 15 'because the film 2 otherwise not by those generated by the reefing rollers 7 centrally on the respective bracket 3 Frictional forces could be pulled over the side portions 3 '' of the bracket 3, which is on both sides to the central temple-apex region 3 '(see in particular FIGS. 1 and 19-21): it would are already caught on the outer edge regions of the curved central apex region 3 '.
the tube section provided with a cross weld 11 is above the previously formed cross weld 11 with a cutting device (not shown) separated from the hose supply, so that the closed hood end between the four brackets 3 falls down, and there hangs down like a bag. Because it is often not only extremely useful to create optimal loading units, but also i.a.
hood cover in the finished wrapping condition not stretched or even in folds on the top of the General cargo stack 1 rests, but - like the hood side walls - is biaxially taut
a so-called follow-up takes place of the reefing rollers 7 driven in the reefing direction raised until the hood cover 10 is (at least i.w.) tightened, and the bracket 3 are then from their spread and reef position acc. arrows 9 (also synchronous) diagonally move to the longitudinal center axis M outwards into a pull-over position in which they each a safety distance s of i.a.
the hood cover 10 When pulling over, the hood cover 10 therefore lies on the top 39 of the piece goods stack 1 and thus forms an abutment against which the hood 4 when lowering the Bracket 3 can slide / be pulled off the bracket 3 successively.
the transverse seam formed during welding is 11 in its middle region 11 'in two layers and in each of its two outer regions 11 " four layers.
the hood cover 10 has two mirror-symmetrically opposite one another V-shaped or triangular multilayer film areas 12, which are also used as film pockets can be referred to because they each have their baselines of rectangular Triangle-forming edge 13 are open.
brackets 3 are exemplified, in particular, with reference to FIGS. 2-6 and 19-21 described. All four brackets 3 are attached to a common lifting frame 14, which is in an upper end position (starting position) at the beginning of each packaging cycle is located, and can be lowered from this in a controlled manner.
the upper edge portion 15 of each bracket 3 has one circular cross section with a diameter d.
the bracket designated as a whole with 3. 2, 3 and 19, which is in a plan view of above (Fig. 19) an isosceles L-shape with a rounded central apex area 3 ', on each of which an i.w. straight outer side section 3 ′′ connects, and of its upper compared to the bracket support section 17 thickened Edge section 15 an i.w. flat support section 17 is directed downwards, on the Lifting frame 14 (horizontally movable) is held in its central (apex) area 3 'with a - according to the exemplary embodiment.

the endless flat belt 52 is by a below the upper bracket edge portion 15 in Supporting section 17 provided centrally, window-like recess 56 (and only after that made endless), whose downward rounded upper edge is the lower deflecting element 53 for forms the flat belt 52. That provided with a greater distance f 'to the upper edge of the bracket 15' window-like recess 56 has a width g that is slightly larger than the width h of the flat belt 52, and a height j which is slightly larger than the thickness k of the flat belt 52, the rest of Fig. 3 (in relation to the other dimensions) for better For the sake of clarity, it is thicker than is actually shown.
the film slides on / from the outside of the belt during the reefing process in the middle of the frame (in folds) down on the bracket support section 17 when its on its outside a downward frictional force is impressed by the reefing rollers 7.
a cylindrically shaped lower deflection element 53 ' can also be attached its longitudinal central axis 58 to be attached to the support section 17 of each bracket 3, if necessary also freely rotatable.
This has the advantage that the flat belt 52 at the contact point Ref roller 7, on which the highest pressure prevails, not with sliding friction over the as Abutment serving role 53 'needs to slide.
the (simple) option is possible a belt tension lost.
These (small) belt conveyors 52 are to be called “passive” because neither of the two "Drums" 20 or 53 'is directly driven, as is the case with a normal belt conveyor is the case, the drive drum of the (drive) torque introduced into it transfers frictionally to the conveyor belt.
the drive is provided in reverse: namely two rollers 20, 53 'driven by the belt 52, and this in turn by the reefing roller 7 the respective reefing unit 5 (if necessary via the film 2), as will be explained in more detail below is described.

the reef roller 7 is dash-dotted in the right part of FIG. 7 in its rest position located. You can from this according to arrow 27 in a with solid lines Working position shown on the roller assembly 20, 53 'or its belt (flat belt) 52 are brought up, first by clamping the film 2.
Fig. 7 is the case in which the axis of rotation 28 of the reefing roller 7 in the middle between the axes of rotation of the two rollers 20, 53 ', and both rollers 20, 53' the same Have diameter d.
the reef roller 7 is one Bracket 3 assigned reefing unit 5 when hitting film on the bracket 3 only with the lower roller 53 'of each bracket 3 is engaged, and in the coming off (sliding) of film the brackets 3, so when pulling over when the film is under considerable transverse expansion, only with the upper roller 20.
FIG. 8 shows an arrangement for such a mode of operation in a highly schematic representation, in which the reefing unit 5 is in turn initially in one with dash-dotted lines shown rest position is out of engagement with the bracket 3 assigned to it which according to arrow 29 when approaching the lower roller 53 ' and then / thereby the arrow 8 is to be driven.
Such or a similar configuration at least one such mode of operation, can be done with or done without strap 52. Since its mode of operation is evident in such a way of working compared to the working method. Fig. 7 resigns, can usually without loss of quality to be dispensed with the belt 52.
FIGS. 9 and 10 Such an embodiment is shown in FIGS. 9 and 10, FIG. 9 again showing the impact process, and FIG. 10 the pulling process.
the training acc. 9 and 10 differs from the training acc. the fig. 7 and 8 also in that the reefing roller 7 of each reefing unit 5 relative to it from its middle position acc. the arrow 31 limits down into a reef position, or acc. the To pivot arrow 32 in FIG. 10 upward into a stripping or film sliding position is.
11-13 give such a configuration of a reefing unit 5 in a less schematic manner Representation again. It differs from the training or presentations gem. 7-10, among others. in that the reefing roller 7 is already in the rest position of the reefing unit 5 has the height position for the pulling process, and from this for contacting Foil on the bracket 3 is pivoted up, and also in that the cylindrical, with an elastic jacket 7 'provided reef roller 7 has a considerably larger diameter has as the two rollers 20, 53 'of each bracket 3, and that the upper roller 20, the after as before has the same diameter d as the lower roller 53 ', to the latter to the outside is offset since the upper edge portion 15 of the bracket 3 with its support portion 17 a Undercut 19 forms, and the lower roller 53 'centrally in the wall of the support section 17 is stored.
the reefing units 5 are simultaneously made to hit film on the brackets 3 their rest position shown in Fig. 11 acc. arrow 27 translationally to each moved to assigned bracket 3, specifically so (see FIG. 12) that the reef roller 7 under "pinching" the film under the specified pressure and at the specified speed in the direction of rotation gem.
the arrow 8 (only) has moved to the lower roller 53 'of the bracket 3 in order to Slide in i.w. auffeffen concentric folds on the support portions 17 of the bracket 3.
the reefing units 5 can again be in their rest position (see Fig. 11) can be retracted (but possibly also initially in their Impact position remain).
each bracket 3 has a considerably larger diameter than the upper one Roll 20, but the diameter is significantly smaller than the diameter of the reef roll 7.
the other relationships are i.w. as in the arrangement according to 11-13.
the training acc. 17 and 18 in turn corresponds to i.w. the training acc. the Fig. 11 - 13, with the essential difference that the jacket 7 'of the reef roller 7 each is spherical, as in the top view of the arrangement acc. 17 in FIG. 18 is recognizable.
this variant has the great advantage that edge pressure should be avoided if the axes of rotation 36 (the Ref roller 7), 37 (the upper roller 20) and 38 (the one under roller 53 ') are not exactly parallel to each other run. But that is even with careful production with a three-roller arrangement esp.
the alternating (horizontal) movable and also about a pivot axis 34 arranged at a distance from it is pivotable on a vertical plane, and alternately on two with mutual Roll-up rollers 20, 53 '(with a still considerably smaller diameter) are brought up must not be easily adhered to with usual manufacturing tolerances. comes it then leads to a relative inclination of the axes 36 and 37 or the axes 36 and 38, the desired goal is not - at least not in - with only cylindrical rollers the desired ideal way - to achieve.
the two rollers 20, 53 ' can be spherical, or all three rollers 7, 20, 53' could have a certain crown have, especially since the jacket 7 'of the reefing rollers 7 expediently made of an elastic Material exists, and compensate for certain irregularities in the axis parallelism can.
FIGS. 19-21 show again in a greatly enlarged manner compared to FIG. 1 Representation of top views of the bracket 3 recognizable at the bottom left in FIG. 1.
the other three Brackets 3 are each formed in the same way.
Fig. 19 corresponds to the bracket designs acc. 2 to 5a
Fig. 20 the bracket designs gem. 6 - 8
Fig. 21 the bracket designs acc. Figures 9-18. It is recognizable in each case that the width h of the flat belt 52 is not nearly over the entire curved middle apex region 3 'of the bracket 3 extends with a middle Radius of curvature r is curved like a quarter arc, but only a fraction of the entire central bracket area 3 '.
FIG. 22 shows - highly schematized - an intermediate state shortly after the start of a packaging cycle, in which the four bow-shaped multifunction elements 3 (of which in the Side view acc. 22 only two are recognizable) a reinforcement hose section 40 already hold in concentric folds to the longitudinal central axis M after they are at the beginning of the Move the packing cycle inwards from its starting position into the pre-opened ones Free end portion of the side gusseted tube fed in, from this receiving position move into their spread or reef position, and after the impact of Foil and the separation of the reinforcement hose section 40 from the hose supply gem.
the arrows 9 in Fig. 1 with simultaneous horizontal transverse expansion of the reinforcing hose section 40 have been moved into the pull-over position shown in FIG. 22.
the reinforcement hose section 40 is therefore considerably smaller horizontal horizontal stretch on the outside of the bow-shaped multifunctional elements 3, and it stands with its upper end portion 41 over the as it were bead-shaped upper edge section 15 of the multifunction elements 3. Because the reinforcement hose section 40 is under considerable transverse stretch, its upper end portion 41 but not (like the rest of the reinforcement tube section 40) through an abutment is supported, the upper end portion 41 of the reinforcing hose section pulls 40 because of the elasticity of the film material thus together towards the center, such as this can be seen in FIG. 22.
the reefing rollers 7 of the reefing units 5 are in the intermediate state gem.
Fig. 15 is not (more) driven. You can after hitting the reinforcement hose section 40 (and possibly a re-arrival or a re-arrival of foil for setting the upper end section 41 of the reinforcement hose section 40) have been moved back to their rest position, or even at a standstill (possibly in idle) in contact with the outside of the reinforcement hose section 40 remain.
the reef rollers 7 are driven again, specifically in the opposite direction of rotation as when hitting, so that when lowering the Multifunctional elements 3 successive sliding of film material of the reinforcement hose section 40 controlled by the multi-function elements 3 and thus without problems can be done.
the reef rollers 7 are located (as in the schematic representation 23 cannot be seen) on the upper roller 20 of each multifunction element 3 under controllable pressure, so that each of the central corner area Multifunctional element 3 sliding film section of the relevant multifunctional element 3 this "leaves under rolling friction" as it were, and thus - also in the neighboring ones Areas of the multifunctional elements 3 up to their mutual end sections towards - can easily slide off the multifunction elements 3.
FIG. 25 shows an intermediate position after reversing the lifting frame drive. That I the film material of the reinforcement hose section 40 due to the embossed in it Circumferential expansion after sliding off the multifunction elements 3 immediately below appropriate static friction on the stack side surfaces, it is possible to create an intended one two-layer design of the reinforcement hose section 40 at the upper end section of the stack 1 with a one-piece hose section: As shown in FIG. 25, when the hood frame drive is reversed, the multi-functional elements 3 now gradually sliding film material is deflected by 180 °, and thereby lies in two layers to the stack 1, first of all, of course, on its side faces.
Fig. 26 in which the reinforcement hose section 40 completely from the bow-shaped multifunction elements 3 has slipped off, it has applied two layers to the upper end portion of the stack 1, and is also in two layers with an upper stretch 46 on the outer edge portion of the Top 39 of the stack 1 all around, so that the sharp edges 39'am all around Edge therefore by a two-layer film reinforcement of a one-piece reinforcement hose section 40 are wrapped.
the lifting frame 14 with the multifunction elements arranged on it 3 move back up to its original position, now around the wrapping hose section (expediently from the same hose stock) in a known manner record, spread, etc., and ultimately pull over the general cargo stack 1, namely in the present exemplary embodiment as a hood 4.
the wrapping hose section 4 is therefore welded with a transverse seam 11 for the purpose of hood formation, if sufficient a lot of film material is pulled off the hose supply and onto the multifunction elements 3 has been reefed, then separated from the hose supply, re-reefed until the hood cover 4 '' runs approximately horizontally in the unexpanded spreading state, and then diagonally Moving the multifunction elements 3 horizontally in their pull-over position stretched transversely, with the subsequent pulling of the hood 4 by the multifunction elements 3 also a vertical stretch is embossed, and the hood lengthwise is dimensioned so that it is in the finished wrapping state (see FIG. 27) with an understretch 47 either place on the underside of the pallet 48 supporting the piece goods stack 1 can (see left in Fig. 27), or to the bottom of the stack 1 (see Fig. 27 right).
FIG. 27 If in Fig. 27 between the two layers of the reinforcement hose section 40 and the reinforcement hose section 40 to the stack 1 or to the hood 4 and / or the individual Portions of the hood 4 and the stack 1 (on the top 39 and its side walls) a (sometimes even considerable) distance (in FIG. 27) is shown, this was done in this schematic representation only for the sake of clarity. Any Spaces between adjacent film sections and these and the Of course, stacks are actually not available in the finished wrapping state. Rather, all the film sections are in the finished wrapping state (FIG. 27) due to the considerable transverse and longitudinal stretches as well as the foil material thereby embossed internal tensions to each other or to stack 1.
reefing rollers 7 each time the film hits the multifunction elements 3 (already in the representation of the finished loading unit according to FIG. 27 have been moved back to their starting position above to start a new packaging cycle initiate) not with the upper rollers 20 in the upper edge portion 15 of the multifunction elements 3 are engaged, but with the lower rollers 25 and that they are not acc. the arrows 9 'are driven, but in the opposite direction. arrows 8.
FIG. 28 shows a piece goods stack 1 as it is in an intermediate state in a method variant before the actual wrapping of the stack 1 with a wrapping tube section (possibly designed as a hood 4) when the "critical point (s)" of the Stack 1 is located in the area of the second uppermost general cargo layer, and stack 1 is therefore in this area can be provided with a single-layer reinforcement hose section 40 before the wrapping hose section is pulled over the stack 1.
a wrapping tube section possibly designed as a hood 4
the reinforcement hose section, initially reefed by the multifunction elements 3, is thereby 40 after its disconnection from the hose supply by means of the Reefing rollers 7 so mounted on the multifunction elements 3 that its upper end section 41 protrudes only slightly above the upper edge sections 15 of the multifunction elements 3, so that when he passes through the height position.
Fig. 23 not (as abutment) can rest firmly on the top 39 of the stack 1, but when lowering the Multifunctional elements 3 over the circumferential edges 39 'of the top 39 of the stack 1 is pulled.
FIG. 28 achieves how this relates to the multifunction elements 3 in FIG. 28 in the upper one right part is indicated by dash-dotted lines, so that are to the upper roles 20 in the upper edge section 15 of the multifunction elements 3 reef rollers 7 gem.
the arrow 8 'reversed to their direction of reef rotation, initially briefly when the lifting frame 14 is stationary or temporarily only slowly lowered further Lift frame 14, so that film material from the multifunction elements 3 upwards are peeled off and lie firmly against the side of the stack under (adhesive) friction can.
the upper edge section 41 of the reinforcing hose section which is already lying laterally against the stack 40 forms when the multifunction elements 3 are lowered further then the required (frictional) abutment, against which when lowering further the multifunctional elements 3 further film material of the reinforcement hose section 40 slide off the multifunction elements 3 (under the controlled action of the reefing rollers 7) until the reinforcement hose section 40 is removed from the multifunction elements 3 has slipped, which are then moved back to their upper starting position to the Wrapping process with the wrapping hose section as such or in training initiate as a film hood 4.
FIG. 29 shows a further exemplary variant, in which the "critical (n) Place (s) "of the piece goods unit 1 to be packed lies in the lower edge area of the pallet 48 (left part of Fig. 22), or by sharp edges 49 'of the bottom 49 of the unit 1 is formed so that - according to the loading unit acc. Fig. 27 - a one-piece, two-layer film reinforcement on a lower peripheral edge of the packaged General cargo unit 1 is to be formed.
the process steps are corresponding and in Knowledge of the above explanations can be determined easily: that of the multifunction elements 3 reinforced reinforcement hose section 40 is so attached to this, that its upper edge section 41 initially either not or only so little in that Intermediate state acc.
the lifting frame 14 with the multifunctional elements 3 has a raised working position reached, in which the first layer of film of the reinforcing hose section 40 is firmly attached has stacked the stack (and possibly the pallet 48) laterally, so that it can be replaced again when the next one Lowering the multifunction elements 3 down a (static friction) abutment for the film to be removed from the multifunctional elements 3, which thereby turns out to be the outer second reinforcement layer firmly against the inner film layer, so the lifting frame drive reversed again, and the lifting frame 14 again moved down to a position, which of the reinforcement tube section 40 is entirely of the multifunction elements 3 has slipped, with its lower edge portion after sliding from the Multifunction elements 3 as the outer lower reinforcement layer on the inner first reinforcement layer sets.
the multifunction elements 3 can then then be used to initiate the actual wrapping process are again moved to their upper starting position, in order to use this for the wrapping process with the wrapping hose section, which may be designed as a hood 4 initiate.
the method according to the invention may appear prima facie relatively time consuming with the As a result of a significant reduction in machine performance (throughput capacity). That is but not really, since it has been shown that with appropriate control itself Relatively complicated loading units with (possibly multiple) multi-layer reinforcement can be realized with surprisingly short cycle times.
the method according to the invention is - in addition to its obvious technical advantages - particularly economical, because you have been working on such problem piece goods units with "critical points" usually instead of a local foil reinforcement has chosen a significantly thicker film overall for the wrapping tube section, and thus already with a doubling of the film thickness, its protective function in the invention Method corresponds to a single-layer film reinforcement at a critical point, the film costs are doubled.
a two-layer film reinforcement at a critical point in the piece goods to be encased (which in the embodiment of the invention Process - as stated - even formed in one piece or in one piece could even correspond to a tripling of material costs in the prior art etc., so that the present invention not only in technical terms, but also under Economic considerations the problems described above in highly satisfactory, easily resolves.
