Abstract
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 (6).Ultra-violet drying assembly, in particular for varnishing on an offsett or gravure machine, characterized in that it comprises a plurality of small emitters (6).
Description
La présente invention a pour objet un ensemble de séchage par ultra-The subject of the present invention is an ultra-drying unit.
violet en particulier pour vernissage sur machine offsett ou héliogravure. Pour le vernissage sur machine offsett ou héliogravure, la largeur utile peut varier de 3000 à 300 mm, ou moins. Pour les émetteurs UV, on dispose l'émetteur en travers. On peut utiliser un grand réflecteur ou plusieurs disposés en quinconce. Le purple in particular for varnishing on an offsett or rotogravure machine. For varnishing on offsett or rotogravure machine, the useful width can vary from 3000 to 300 mm, or less. For UV emitters, the transmitter is arranged crosswise. One can use a large reflector or several arranged in staggered rows. The
coût d'exploitation reste identique quelque soit la largeur du papier. 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'extrème, ils peuvent Furthermore, from a certain length, the reflectors tend to arch and they collapse. In the extreme, they can
venir heurter les pinces de maintien du papier qui défile. hit the clips holding the moving 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 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 the
mercure.mercury.
Ainsi si les encres absorbent à des longeurs d'onde différentes, la vitesse d'avance doit être liée à un temps de réticulation So if the inks absorb at different wavelengths, the speed of advance must be linked to a crosslinking time
plus ou moins long.more or less long.
L'invention a pour objet de remédier à ces différents The object of the invention is to remedy these various
inconvénients des dispositifs de l'art antérieur. disadvantages 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 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
pluralité de petits émetteurs.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. 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 Advantageously, the transmitters will be arranged end to end on several lines, offset from one another with respect to those of the adjacent lines. To reduce the crosslinking times, it is possible for smaller emitters to use different metal iodides such as - Iron / cobalt, - Gallium / lead - Thallium
ceci non limitativement.this without limitation.
La vitesse est ainsi augmentée à moindres frais, car on a une The speed is thus increased at lower cost, because there is a
bonne concordance avec les spectres des encres ou des vernis. good agreement with the spectra of inks or varnishes.

De préférence les longueurs d'arc seront au maximum de 200 mm, Preferably the arc lengths will be at most 200 mm,
car le régime devient instable au-delà de cette limite. because the regime becomes unstable beyond this limit.
Du fait de cette faible longueur, les émetteurs ne peuvent pas s'affaisser. Selon un mode avantageux de mise en oeuvre, on panachera les Due to this short length, the transmitters cannot sag. According to an advantageous mode of implementation, the
émetteurs sur un même dispositif.transmitters on the same device.
On comprendra mieux l'invention à l'aide de la description The invention will be better understood using the description
faite ci-après en référence au dessin unique annexé qui est une vue en made below with reference to the single appended drawing which is a view in
plan d'un dispositif de séchage conforme à l'invention. plan 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 The device essentially consists of a box (1) placed above a carpet on which any product passes.
recouvert d'une encre ou d'un vernis à polymériser. covered with an ink or a varnish to cure.
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. Les émetteurs, de faible longueur, fonctionnent à des tensions 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. The short length transmitters operate at voltages
inférieures à 380 volts.less than 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). 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 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). 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
les faibles tensions permettront d'utiliser un cablage électrique courant. 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 Finally, according to an advantageous embodiment, the device can be sectored longitudinally in operation for
des faibles largeurs de bande qui défilent. small bandwidths that scroll.
