Abstract

The strip processing machine has a single head facing the strip which is driven past the head via a path that exposes firstly one face then the other to the head. The strip arrives from the delivery spool (1) with face A upward and passing under the processing head (2), then passes over two rollers (3,6) which turn the path of the strip through 180 degrees . The strip then passes over a triangular plate (4) which returns the strip on itself through 180 degrees , with the face B facing upward. The strip now passes under the processing head (2), travelling in the same direction as the strip from the spool, but being delivered to the exit of the machine.

Description

La présente invention concerne un dispositif permettant d'imprimer d'un seul passage avec la même tête d'impression, un ruban recto/verso.The present invention relates to a device for printing a single pass with the same printhead, a recto / verso ribbon.

La présente invention se réfère aux machines à imprimer en continu recto/verso, en partant d'une bobine. Ces machines sont munies d'une tête d'impression pour le recto et d'une tête d'impression pour le verso.The present invention relates to machines for continuous printing on both sides, starting from a spool. These machines are equipped with a print head for the front and a print head for the back.

L'invention vise à permettre d'imprimer, côte à côte, le recto et le verso, d'un seul passage, avec une seule tête d'impression, et donc de réaliser un matériel beaucoup plus économique. En effet, le fait de n'avoir qu'une seule tête d'impression, entraine l'économie d'une deuxième tête, ainsi que de toute sa mécanique de commande. La machine devient, également, beaucoup plus compacte.The invention aims to allow printing, side by side, the front and back, in a single pass, with a single printhead, and therefore to produce a much more economical material. Indeed, the fact of having only one print head, results in the economy of a second head, as well as all its control mechanics. The machine also becomes much more compact.

Le terme de "ruban" sera utilisé dans le texte suivant, afin d'en faciliter la lecture, mais ne sera pas limitatif dans sa définition qui englobera tous les matériaux sortant d'une bobine, ainsi que tous les matériaux travaillés en continu. De même, le terme "impression" englobera les opérations d'imprimerie, de marquage, de compostage, de repiquage, d'enduction, d'encollage, de dépose.The term "ribbon" will be used in the following text, in order to facilitate reading, but will not be limiting in its definition which will include all the materials leaving a reel, as well as all the materials worked continuously. Likewise, the term "printing" will include printing, marking, composting, transplanting, coating, gluing, depositing.

Le dispositif objet du présent brevet, a pour objet de pouvoir imprimer, marquer, composter, repiquer, enduire, encoller, déposer, simultanément et côte à côte sur les 2 faces recto/verso d'un ruban de tissu, tissu enduit, papier, cartonnette, matière synthétique ou tout autre, en, imprimerie, marquage à chaud, impression thermique et matricielle, transfert thermique, jet d'encre, impression laser, sérigraphie, héliogravure, typographie, flexographie, offset, enduction, encollage, que cette impression se fasse sur arrêt du ruban ou en continu. Ce dispositif est étudié pour être installé sur toutes machines d'imprimerie, de marquage, de compostage, de pose, d'enduction ou autres, chaque fois qu'une opération recto/verso est demandée dans le même passage.The object of this patent device is to be able to print, mark, compost, transplant, coat, glue, deposit, simultaneously and side by side on the 2 front / back sides of a fabric ribbon, coated fabric, paper, cardboard, synthetic material or any other, in, printing, hot stamping, thermal and matrix printing, thermal transfer, inkjet, laser printing, screen printing, rotogravure, letterpress, flexography, offset, coating, gluing, whether this printing is made on tape stop or continuously. This device is designed to be installed on all printing, marking, composting, laying, coating or other machines, each time a front / back operation is requested in the same passage.

A titre d'exemple non limitatif, on va décrire un prototype qui a été réalisé selon l'invention. Les essais réalisés sur une machine d'impression thermique, dont le bâti est représenté par la piece (n° 9) ( Figure : 1), montrent que le cheminement du ruban s'opère de la façon suivante ( Figure : 1) : sortant de la bobine mère (n° 1) face A dessus, le ruban passe sous la barre (n° 5), ensuite passe entre la tête d'impression (n° 2) et la contrepartie (n° 3) où il recoit l'impression recto, se dirige sous la barre (n° 6) alors qu'apparait la face B. Le ruban se trouve alors retourné. La face A qui était dessus se retrouve dessous. Le ruban se dirige ensuite sous le guide en angle à 90° (n° 4), qu'il enveloppe, laissant réapparaitre la face A pendant qu'il se trouve sur le guide à 90° (n° 4), alors que réapparait la face B à sa sortie du guide en angle à 90° (n°4). Le ruban continue son trajet en face B, jusqu'au moment où il s'introduit entre la tête d'impression (n° 2) et la contrepartie (n° 3) pour y être imprimé en face B. On comprend, facilement, que la face A et B recevront simultanément l'impression de la tête d'impression (n° 2). Dans le cas de la machine réalisée, l'entrainement du ruban est fait par la contrepartie (n° 3) s'appuyant sur la tête d'impression (n° 2). La tête d'impression (n° 2) et la contrepartie (n° 3) peuvent être cylindriques ou plates, suivant le type de la machine utilisée, l'entrainement du ruban se faisant alors à l'entrée ou à la sortie de l'impression. Les pièces (n° 5) ou (n° 6) ne sont pas indispensables.By way of nonlimiting example, we will describe a prototype which has been produced according to the invention. The tests carried out on a thermal printing machine, the frame of which is represented by the part (n ° 9) (Figure: 1), show that the routing of the ribbon takes place as follows (Figure: 1): outgoing of the mother spool (n ° 1) face A above, the ribbon passes under the bar (n ° 5), then passes between the print head (n ° 2) and the counterpart (n ° 3) where it receives the impression front, goes under the bar (n ° 6) while side B appears. The ribbon is then turned over. Side A which was above is found below. The ribbon then goes under the 90 ° angle guide (n ° 4), which it wraps, letting face A reappear while it is on the 90 ° guide (n ° 4), while reappears side B at its exit from the guide at a 90 ° angle (n ° 4). The ribbon continues its journey on side B, until it enters between the print head (n ° 2) and the counterpart (n ° 3) to be printed there on side B. We understand, easily, that side A and B will simultaneously receive the print from the print head (No. 2). In the case of the machine produced, the ribbon is driven by the counterpart (n ° 3) resting on the print head (n ° 2). The print head (n ° 2) and the counterpart (n ° 3) can be cylindrical or flat, depending on the type of machine used, the ribbon is then fed into or out of the machine. 'impression. The parts (n ° 5) or (n ° 6) are not essential.

Comme son appellation l'indique, le guide en angle à 90° (n° 4) forme un angle à 90°. Le sommet de cet angle est opposé à la tête d'impression. La ligne médiane de ce triangle est parallèle au sens du défilement du ruban. Vue de dessus, cette ligne médiane se confond avec les arêtes jointives du brin du ruban arrivant dans le guide en angle à 90° (n°4) et du brin du ruban repartant du guide en angle à 90° (n° 4) pour aller à la tête d'impression.As its name suggests, the 90 ° angle guide (n ° 4) forms a 90 ° angle. The top of this angle is opposite the print head. The center line of this triangle is parallel to the direction of travel of the ribbon. Seen from above, this center line merges with the contiguous edges of the ribbon strand arriving in the 90 ° angle guide (n ° 4) and the ribbon strand leaving the 90 ° angle guide (n ° 4) to go to the print head.

Les figures 4 et 5 montrent bien le cheminement du ruban et son passage autour du guide en angle à 90° (n° 4). Pour être bord à bord lors de l'impression, le ruban doit monter jusqu'au sommet de l'angle à 90°, position qu'il conservera de lui-même (figure 4). Le dispositif permet aussi d'écarter le brin arrivant du brin partant, en disposant une butée ou en pratiquant un décrochement sur les 2 côtés du triangle sur lesquels glisse le ruban (figure 5).Figures 4 and 5 clearly show the path of the ribbon and its passage around the guide at a 90 ° angle (n ° 4). To be edge to edge when printing, the ribbon must go up to the top of the 90 ° angle, a position it will keep on its own (Figure 4). The device also makes it possible to separate the strand arriving from the departing strand, by placing a stop or by making a step on the 2 sides of the triangle on which the ribbon slides (FIG. 5).

Cette butée ou décrochement évitera au ruban de monter au sommet de l'angle. L'espace laissé libre facilitera certaines opérations.This stop or detachment will prevent the tape from rising to the top of the angle. The space left free will facilitate certain operations.

Le guide en angle à 90° (n° 4), peut être fixe ou mobile. Un mouvement transversal CD ou DC sur l'axe (n° 14) (figure 2), c'est-à-dire, perpendiculaire au défilement du ruban, permet l'alignement du ruban par rapport à l'impression. Le guide en angle à 90° (n° 4) est bloqué sur l'axe (n° 14) par une vis (n° 15), lorsque la bonne position est déterminée. Ce déplacement peut-être supprimé et remplacé par des triangles de dimensions différentes, suivant la largeur du ruban utilisé (figure 3), présentés sur cette figure (n° 3) par des triangles en pointillé fixés par la vis (n° 16). Un mouvement longitudinal EF ou FE (figure 3) (sens du défilement du ruban), permet de régler, par glissement du ruban sur le guide en angle à 90° (n° 4) la superposition de l'impression recto, par rapport à l'impression verso. Ces deux mouvements, c'est-à-dire, transversal CD ou DC ou longitudinal EF ou FE, peuvent, également, être supprimés dans certain cas, lorsque la machine est pilotée par ordinateur, en déplaçant l'impression à l'écran, de façon à aligner cette impression par rapport au ruban, et à régler la superposition du recto par rapport au verso.The 90 ° angle guide (n ° 4) can be fixed or mobile. A transverse movement CD or DC on the axis (n ° 14) (figure 2), that is to say, perpendicular to the running of the ribbon, allows the alignment of the ribbon with respect to the printing. The 90 ° angle guide (n ° 4) is locked on the axis (n ° 14) by a screw (n ° 15), when the correct position is determined. This movement can be eliminated and replaced by triangles of different dimensions, depending on the width of the ribbon used (figure 3), presented in this figure (n ° 3) by dotted triangles fixed by the screw (n ° 16). A longitudinal movement EF or FE (Figure 3) (direction of travel of the ribbon), allows to adjust, by sliding the ribbon on the guide at a 90 ° angle (n ° 4) the overlapping of the front printing, compared to the back printing. These two movements, that is to say, transverse CD or DC or longitudinal EF or FE, can also be eliminated in certain cases, when the machine is controlled by computer, by moving the printing on the screen, so as to align this impression with respect to the ribbon, and to adjust the overlap of the front with respect to the back.

Le guide en angle a 90° (n° 4) est constitué d'une simple plaque monobloc qui caractérise l'invention. Cette plaque forme un angle à 90° et peut être en métal, plastique ou tout autre matériau. Ce guide en angle à 90° (n° 4) peut aussi être constitué de plusieurs parties totalisant un angle à 90°, que ces parties soient sur le même plan ou sur des plans décalés. De même, le guide en angle à 90° (n° 4) peut-être remplacé par un guide conique.The 90 ° angle guide (n ° 4) consists of a simple monobloc plate which characterizes the invention. This plate forms a 90 ° angle and can be made of metal, plastic or any other material. This 90 ° angle guide (n ° 4) can also consist of several parts totaling a 90 ° angle, whether these parts are on the same plane or on offset planes. Likewise, the 90 ° angle guide (n ° 4) can be replaced by a conical guide.

Ce guide en angle à 90° (n° 4) peut avoir une autre position, vis à vis de la tête d'impression, du moment que la ligne médiane du guide en angle à 90° (n°4) reste parallèle au défilement du ruban sous la tête d'impression (n° 2).This 90 ° angle guide (n ° 4) can have another position, with respect to the print head, as long as the center line of the 90 ° angle guide (n ° 4) remains parallel to the scrolling ribbon under the print head (# 2).

Au cours des essais, il a été constaté que suivant la rugosité des rubans employés, ainsi que la qualité de la matière employée pour la réalisation du guide en angle à 90° (n° 4), que sous l'action de l'inertie donnée au démarrage, le ruban se bridait autour du guide en angle à 90° (n° 4), en augmentant le frottement, ce qui dans certains cas, peut amener à un décalage à l'impression. Il est donc, dans ce cas, nécessaire de monter l'ensemble sur un système d'amortisseur réagissant au moment où le ruban est sollicité à l'entrainement, ce qui caractérise aussi l'invention. Le guide en angle à 90° (n° 4) est alors fixé sur un support (n° 7) traversé par une tige filetée (n° 8) qui permet de déplacer l'ensemble du guide en angle à 90° (n° 4) et son support (n° 7) dans le sens longitudinal EF ou FE (figure 3). La tige filetée (n° 8) est fixée au bâti (n°9) d'un côté par un palier (n° 10) et de l'autre côté, par un palier (n° 11). Cette tige filetée (n° 8) est commandée par un bouton (n° 12). Entre le bouton (n°12) et le palier (n° 11) un ressort est intercalé. Ce ressort(n° 13) a pour rôle d'amortir la tension du ruban et diminuer le frottement du ruban sur le guide en angle à 90° (n° 4). Tout autre système d'amortisseur peut, également, être utilisé (hydraulique, pneumatique, etc...). La (figure 3) montre le système dans le cas ou l'on change le guide en angle à 90° (n° 4) en fonction de la largeur du ruban à imprimer.During the tests, it was noted that according to the roughness of the ribbons used, as well as the quality of the material used for the realization of the guide at 90 ° angle (n ° 4), only under the action of inertia given at start-up, the ribbon curled around the guide at a 90 ° angle (n ° 4), increasing the friction, which in some cases can lead to a printing offset. It is therefore, in this case, necessary to mount the assembly on a damper system reacting at the moment when the ribbon is stressed during training, which also characterizes the invention. The 90 ° angle guide (n ° 4) is then fixed on a support (n ° 7) crossed by a threaded rod (n ° 8) which allows to move the whole of the 90 ° angle guide (n ° 4) and its support (n ° 7) in the longitudinal direction EF or FE (figure 3). The threaded rod (n ° 8) is fixed to the frame (n ° 9) on one side by a bearing (n ° 10) and on the other side, by a bearing (n ° 11). This threaded rod (n ° 8) is controlled by a button (n ° 12). Between the button (n ° 12) and the bearing (n ° 11) a spring is inserted. The role of this spring (n ° 13) is to dampen the tension of the ribbon and reduce the friction of the ribbon on the guide at an angle of 90 ° (n ° 4). Any other shock absorber system can also be used (hydraulic, pneumatic, etc.). The (figure 3) shows the system in the case where the guide is changed to a 90 ° angle (n ° 4) depending on the width of the ribbon to be printed.

L'intérêt de l'invention réside dans le principe du guide en angle à 90° (n° 4) et de son ressort amortisseur (n° 13) qui permettent l'impression côte à côte et simultanée du recto et du verso sur une machine de moindre coût et de moindre encombrement.The advantage of the invention lies in the principle of the 90 ° angle guide (n ° 4) and its damping spring (n ° 13) which allow the side by side and simultaneous printing of the front and back on a lower cost machine and less space.
