Abstract
Description
La présente invention a pour objet un ensemble de séchage par ultra-violet en particulier pour vernissage sur machine offsett ou héliogravure.The subject of the present invention is an ultraviolet drying assembly, in particular for varnishing on an offsett or rotogravure machine.
Pour le vernissage sur machine offsett ou héliogravure, la largeur utile peut varier de 3000 à 300 mm, ou moins.For varnishing on offsett or rotogravure machine, the useful width can vary from 3000 to 300 mm, or less.
Pour les émetteurs UV, on dispose l'émetteur en travers. On peut utiliser un grand réflecteur ou plusieurs disposés en quinconce. Le coût d'exploitation reste identique quelque soit la largeur du papier.For UV emitters, the transmitter is arranged crosswise. One can use a large reflector or several arranged in staggered rows. The operating cost remains the same whatever the width of the paper.
Par ailleurs à partir d'une certaine longueur les réflecteurs ont tendance à s'arquer et ils s'affaissent. A l'extrême , ils peuvent venir heurter les pinces de maintien du papier qui défile.Furthermore, from a certain length, the reflectors tend to arch and they collapse. In the extreme, they can strike the clips holding the scrolling paper.
D'autre part, pour des raisons financières et physiques, on utilise seulement des émetteurs au mercure. La polymérisation des encres UV et des vernis se fait par rapport aux seules raies spectrales du mercure.On the other hand, for financial and physical reasons, only mercury emitters are used. The polymerization of UV inks and varnishes is done in relation to only the spectral lines of mercury.
Ainsi si les encres absorbent à des longeurs d'onde différentes, la vitesse d'avance doit être liée à un temps de réticulation plus ou moins long.Thus if the inks absorb at different wavelengths, the speed of advance must be linked to a more or less long crosslinking time.
L'invention a pour objet de remédier à ces différents inconvénients des dispositifs de l'art antérieur.The object of the invention is to remedy these various drawbacks of the devices of the prior art.
Conformément à l'invention, ce résultat est obtenu avec un ensemble de séchage par ultra-violet en particulier pour vernissage sur machine offsett ou héliogravure, caractérisé en ce qu'il comporte une pluralité de petits émetteurs.In accordance with the invention, this result is obtained with an ultraviolet drying assembly, in particular for varnishing on an offsett or rotogravure machine, characterized in that it comprises a plurality of small transmitters.
Avantageusement, les émetteurs seront disposés bout à bout sur plusieurs lignes, décalés les uns des autres par rapport à ceux des lignes adjacentes.Advantageously, the transmitters will be arranged end to end on several lines, offset from one another with respect to those of the adjacent lines.
Pour diminuer les temps de réticulation on peut pour des émetteurs plus petits utiliser des iodures métalliques différents tels que :
- Fer/cobalt,
- Gallium/plomb
- Thallium
ceci non limitativement.To reduce the crosslinking times, it is possible for smaller transmitters to use different metal iodides such as:
- Iron / cobalt,
- Gallium / lead
- Thallium
this without limitation.
La vitesse est ainsi augmentée à moindres frais, car on a une bonne concordance avec les spectres des encres ou des vernis.The speed is thus increased at lower cost, because there is a good agreement with the spectra of inks or varnishes.
De préférence les longueurs d'arc seront au maximum de 200 mm, car le régime devient instable au-delà de cette limite.Preferably the arc lengths will be at most 200 mm, because the speed becomes unstable beyond this limit.
Du fait de cette faible longueur, les émetteurs ne peuvent pas s'affaisser.Due to this short length, the transmitters cannot sag.
Selon un mode avantageux de mise en oeuvre, on panachera les émetteurs sur un même dispositif.According to an advantageous mode of implementation, the transmitters will be mixed on the same device.
On comprendra mieux l'invention à l'aide de la description faite ci-après en référence au dessin unique annexé qui est une vue en plan d'un dispositif de séchage conforme à l'invention.The invention will be better understood with the aid of the description given below with reference to the single appended drawing which is a plan view of a drying device according to the invention.
Le dispositif se compose essentiellement d'un caisson (1) disposé au dessus d'un tapis sur lequel défile un produit quelconque recouvert d'une encre ou d'un vernis à polymériser.The device essentially consists of a box (1) placed above a carpet on which any product covered by an ink or a varnish to be polymerized.
Selon l'invention le dispositif comporte une pluralité de lignes (2 à 5), par exemple au nombre de quatre, d'émetteurs (6) disposés bout à bout. Les émetteurs sont décalés l'un par rapport à l'autre d'une ligne à la ligne adjacente de manière à obtenir une zone d'émission uniforme.According to the invention, the device comprises a plurality of lines (2 to 5), for example four in number, of transmitters (6) arranged end to end. The transmitters are offset from each other by one line to the adjacent line so as to obtain a uniform emission area.
Les émetteurs, de faible longueur, fonctionnent à des tensions inférieures à 380 volts.The short length transmitters operate at voltages below 380 volts.
Les tensions d'utilisation sont celles de la sécurité maximale pour intervenir sur le sécheur et sur l'armoire électrique sans avoir à arrêter la machine tout en restant hors de la législation du travail (sécurité).The operating voltages are those of maximum safety for working on the dryer and on the electrical cabinet without having to stop the machine while remaining outside of labor legislation (safety).
L'intervention peut être effectuée par un électricien ordinaire, et non par un électricien spécialisé dans les hautes tensions, comme c'est le cas pour les dispositifs de l'art antérieur. Bien entendu les faibles tensions permettront d'utiliser un cablage électrique courant.The intervention can be carried out by an ordinary electrician, and not by an electrician specialized in high voltages, as is the case for the devices of the prior art. Of course the low voltages will allow the use of current electrical wiring.
Enfin, selon un mode avantageux de mise en oeuvre, le dispositif pourra être sectorisé longitudinalement en fonctionnement pour des faibles largeurs de bande qui défilent.Finally, according to an advantageous mode of implementation, the device can be sectored longitudinally in operation for small widths of band which pass.
