Description

La présente invention concerne un dispositif d'approvisionnement en bande d'une machine, notamment d'une machine d'emballage ou d'arts graphiques, comprenant un châssis sur lequel sont montés, d'une part, au moins un arbre destiné à recevoir une bobine de bande et apte à dérouler ladite bande de film vers des moyens de mise sous tension et, d'autre part, des moyens aptes à effectuer un renvoi d'angle de ladite bande vers ladite machine.The present invention relates to a tape supply device for a machine, in particular a packaging machine or graphic arts machine, comprising a frame on which are mounted, on the one hand, at least one shaft intended to receive a tape reel and adapted to unwind said film strip to means for energizing and, secondly, means adapted to perform a return of angle of said web to said machine.

La présente invention entre dans le domaine du convoyage de bande pour l'alimentation d'une machine, préférentiellement de bande constituée d'un film plastique pour l'alimentation de machine d'emballage. Une telle machine trouve son application dans de nombreux domaines, mais tout particulièrement dans l'emballage alimentaire, par exemple dans le cas d'une thermoformeuse, d'une operculeuse ou similaire.The present invention is in the field of conveyor belt for feeding a machine, preferably strip consisting of a plastic film for feeding packaging machine. Such a machine finds application in many fields, but especially in food packaging, for example in the case of a thermoformer, a tray sealer or the like.

A ce propos, dans le cas d'une thermoformeuse ou d'une operculeuse, la bande de la bobine est constituée en matière plastique, comme du polypropylène, du polyéthylène, du polychlorure de vinyle (PVC) ou similaire.In this regard, in the case of a thermoformer or a sealing machine, the strip of the coil is made of plastic, such as polypropylene, polyethylene, polyvinyl chloride (PVC) or the like.

Sur une chaîne de fabrication, une machine d'emballage est alimentée par déroulement d'une bobine de film d'emballage montée sur un dispositif d'alimentation. Un tel dispositif d'alimentation comprend de manière connue un arbre dérouleur sur lequel la bobine est enfilée horizontalement, ainsi que des moyens d'appel et de tension de la bande issue du déroulement de la bobine. La bande de film alimente donc avec une tension constante l'entrée de ladite machine d'emballage.On a production line, a packaging machine is fed by unwinding a packaging film spool mounted on a feed device. Such a feeding device comprises, in a known manner, an unwinding shaft on which the spool is threaded horizontally, as well as means for calling and tensioning the web resulting from unwinding of the spool. The film strip thus supplies the input of said packaging machine with a constant voltage.

Un tel dispositif d'alimentation est généralement situé en bout de chaîne, dans sa continuité, pour alimenter en ligne ladite machine d'emballage. Toutefois, cette disposition pose un problème d'encombrement et d'espace requis pour le chargement et le déchargement de la bobine sur celui-ci, notamment à l'aide d'un chariot de type élévateur ou autre qui nécessite un espace de mouvement important. De plus, la machine d'emballage n'est pas forcément située en bout de chaîne et une longueur importante de film est souvent déroulée depuis l'extrémité de la chaîne où est situé le dispositif d'alimentation et l'emplacement de ladite machine d'emballage. Cette longueur est gâchée quand le film se décale latéralement au travers et donc à la sortie du dispositif d'alimentation et qu'il n'est plus positionné en vis-à-vis des produits à emballer au niveau de la machine. En effet, le réglage nécessaire pour compenser ce décalage implique la perte du film déjà déroulé. De surcroît, le décalage dudit film peut entraîner un mauvais emballage des produits, ces derniers et souvent leur contenu sont alors perdus.Such a feed device is generally located at the end of the chain, in its continuity, to feed line said packaging machine. However, this provision poses a problem of space and space required for the loading and unloading of the coil thereon, in particular using a lift-type carriage or the like which requires a large movement space. In addition, the packaging machine is not necessarily located at the end of the chain and a large length of film is often unwound from the end of the chain where the feed device is located and the location of said machine. 'packaging. This length is wasted when the film is shifted laterally through and therefore at the outlet of the feeder and it is no longer positioned vis-à-vis the products to be packaged at the machine. Indeed, the adjustment necessary to compensate for this shift involves the loss of the film already unwound. In addition, the shift of said film can lead to poor packaging of products, the latter and often their content are lost.

C'est pourquoi il convient de réduire cette longueur de film déroulé entre le dispositif d'alimentation et la machine d'emballage. Des dispositifs d'alimentation de l'état de la technique comprennent des moyens aptes à former un retour d'angle dans le déroulement de la bande. Ainsi, un tel dispositif d'alimentation peut être disposé latéralement à la chaîne d'emballage, à proximité de la machine. Pour ce faire, en sortie du dispositif d'alimentation, un arbre de renvoi d'équerre, orienté à 45° par rapport à l'arbre dérouleur, oriente la bande à 90° vers l'entrée de la machine d'emballage. Un tel dispositif est décrit dans le document WO 94/10039 A .This is why it is necessary to reduce the length of film unwound between the feed device and the packaging machine. Feeders of the state of the art comprise means capable of forming a return angle in the unfolding of the strip. Thus, such a feeding device can be arranged laterally to the packaging line, near the machine. To do this, at the output of the feeder, a straight deflection shaft, oriented at 45 ° to the unwinding shaft, orients the strip at 90 ° to the entrance of the packaging machine. Such a device is described in the document WO 94/10039 A .

Un autre avantage réside dans le fait que l'espace de manipulation de la bobine par un chariot est plus important de part et d'autre de la chaîne plutôt qu'à une extrémité, facilitant ainsi le chargement et le déchargement de la bobine.Another advantage lies in the fact that the handling space of the reel by a trolley is greater on either side of the chain rather than at one end, thus facilitating the loading and unloading of the reel.

Toutefois, un inconvénient de ces dispositifs réside encore dans le gâchis de bande lorsqu'un décalage de la bande survient. En effet, un moyen simple et efficace de pallier ce décalage est d'appliquer un réglage audit arbre dérouleur, par translation latérale, de manière à compenser le décalage en sortie du dispositif d'alimentation et donc en entrée de la machine d'emballage. Pour autant, la longueur de bande déroulée au travers des moyens d'appel et de tension du film, de l'ordre de plusieurs dizaines de mètres, a déjà subi le décalage et génère de la gâche.However, a disadvantage of these devices is still the tape waste when a tape offset occurs. In Indeed, a simple and effective way to overcome this shift is to apply a setting to said unwinding shaft, by lateral translation, so as to compensate for the offset at the output of the feed device and therefore at the input of the packaging machine. However, the length of tape unwound through the means of appeal and tension of the film, of the order of several tens of meters, has already undergone the shift and generates waste.

Un autre type de réglage est décrit dans le document DE 2610957 au travers d'une rotation par rapport à un pivot vertical. Toutefois, cette solution reste encombrante et complexe à mettre en oeuvre pour une solution peu satisfaisante.Another type of setting is described in the document DE 2610957 through a rotation relative to a vertical pivot. However, this solution remains cumbersome and complex to implement for an unsatisfactory solution.

L'invention a pour but de pallier les inconvénients de l'état de la technique en proposant un système d'approvisionnement en film d'une machine d'emballage à partir d'un dispositif d'alimentation permettant une diminution de la gâche de film lors du décalage de ce dernier au cours de son déroulement. De plus, ce système offre toujours une disposition avantageuse dudit dispositif d'alimentation, prévu de surcroît particulièrement compact, économisant ainsi l'espace et facilitant l'accès et la manipulation.The object of the invention is to overcome the drawbacks of the state of the art by proposing a film supply system of a packaging machine from a feed device allowing a reduction of the film waste. when the latter is shifted during its course. In addition, this system always offers an advantageous arrangement of said feed device, which is moreover particularly compact, thus saving space and facilitating access and handling.

Pour ce faire, la présente invention concerne un dispositif d'approvisionnement en bande d'une machine, notamment d'une machine d'emballage ou d'arts graphiques, comprenant un châssis sur lequel sont montés, d'une part, au moins un arbre destiné à recevoir une bobine de bande et apte à dérouler ladite bande vers des moyens de mise sous tension et, d'autre part, des moyens aptes à effectuer un renvoi d'angle de ladite bande vers ladite machine.To do this, the present invention relates to a device for supplying a machine, in particular a packaging machine or graphic arts machine, comprising a frame on which are mounted, on the one hand, at least one shaft for receiving a tape reel and adapted to unroll said tape to means for energizing and, secondly, means adapted to perform a return angle of said tape to said machine.

Une caractéristique de l'invention réside dans le fait que lesdits moyens de renvoi d'angle, notamment de renvoi d'équerre, sont mobiles en translation au travers de moyens de réglage.A feature of the invention lies in the fact that said angle deflection means, in particular angle deflection, are movable in translation through adjustment means.

Avantageusement, les moyens de réglages comprennent au moins un coulisseau coulissant sur un axe solidaire dudit châssis.Advantageously, the adjustment means comprise at least one slider sliding on an integral axis of said frame.

De préférence, les moyens de réglages comprennent des moyens de commande du réglage.Preferably, the adjustment means comprise adjustment control means.

De plus, les moyens de commande du réglage sont automatisés et/ou gradués.In addition, the adjustment control means are automated and / or graduated.

L'invention concerne aussi une chaîne d'emballage comprenant une machine, telle une machine d'arts graphiques, d'emballage, une thermoformeuse ou une operculeuse, alimentée en bande par un dispositif d'approvisionnement selon l'invention.The invention also relates to a packaging line comprising a machine, such as a graphic arts machine, packaging, a thermoformer or a sealing machine, fed in a band by a supply device according to the invention.

  • the figure 2 is a partial representation of a part of the device according to the invention; and
  • the figure 3 is another partial representation of a part of the device according to the invention.

La présente invention concerne un dispositif d'approvisionnement 1 en bande d'une machine sur une chaîne 2. Préférentiellement, mais non limitativement, l'invention trouvera son application dans l'approvisionnement de machine d'emballage sur une chaîne d'emballage 2. La présente invention trouvera aussi son application dans le domaine de l'approvisionnement de machine d'arts graphiques, par exemple dans le domaine de l'imprimerie ou autre.The present invention relates to a supply device 1 in strip of a machine on a chain 2. Preferably, but not exclusively, the invention will find its application in the supply of packaging machine on a packaging line 2. The present invention will also find application in the field of the supply of graphic arts machine, for example in the field of printing or other.

Comme visible sur le mode de réalisation de la figures 1, le dispositif d'approvisionnement 1 comprend un châssis 3 sur lequel sont montés au moins un arbre 4 destiné à recevoir une bobine 5 et apte à dérouler une bande 6 vers des moyens 7 de mise sous tension de ladite bande 6.As visible on the embodiment of the figures 1 , the supply device 1 comprises a frame 3 on which are mounted at least one shaft 4 intended to receive a coil 5 and able to unwind a strip 6 towards means 7 for energizing said strip 6.

A ce propos, le dispositif d'approvisionnement 1 selon l'invention peut être destiné à tout type d'emballage, mais tout particulièrement à l'emballage dans le domaine alimentaire. Il convient alors de noter que, dans ce cas, la bobine 5 est constituée d'un film en matière plastique, comme du polypropylène, du polyéthylène, du polychlorure de vinyle ou analogue. La machine d'emballage, non représentée, peut alors être une thermoformeuse, un operculeuse ou similaire. De plus, le dispositif d'approvisionnement 1 selon l'invention concerne tout particulièrement un film plastique d'une forte épaisseur, de l'ordre de plusieurs centaines de microns, par exemple 500 microns.In this regard, the supply device 1 according to the invention can be intended for any type of packaging, but especially packaging in the food field. It should then be noted that, in this case, the coil 5 is made of a plastic film, such as polypropylene, polyethylene, polyvinyl chloride or the like. The packaging machine, not shown, can then be a thermoformer, a traysealer or the like. In addition, the supply device 1 according to the invention particularly relates to a plastic film with a large thickness, of the order of several hundred microns, for example 500 microns.

Toutefois, dans l'imprimerie ou le domaine du textile, la bobine 5 sera réciproquement constituée de papier ou de tissus.However, in printing or textile field, the coil 5 will be reciprocally made of paper or fabrics.

La figure 1 concerne un mode de réalisation du dispositif d'alimentation de film supérieur. Comme visible sur cette figure, le dispositif d'approvisionnement 1 est positionné latéralement par rapport à la chaîne d'emballage 2 de manière à dégager l'espace situé en extrémité de ladite chaîne 2. Ce positionnement de côté offre l'avantage d'économiser de l'espace en limitant l'encombrement du fait que le dispositif 1 est prévu particulièrement compact. De plus, cette situation permet un chargement et un déchargement aisé des bobines 5 sur ledit dispositif d'emballage 1.The figure 1 relates to an embodiment of the upper film feeding device. As visible on this 1, the supply device 1 is positioned laterally with respect to the packaging line 2 so as to clear the space at the end of said chain 2. This lateral positioning has the advantage of saving space by limiting the size because the device 1 is particularly compact. In addition, this situation allows easy loading and unloading of the coils 5 on said packaging device 1.

Afin de permettre l'alimentation de la machine d'emballage, le dispositif d'approvisionnement 1 comprend des moyens 8 aptes à effectuer un renvoi d'angle, préférentiellement d'équerre, de ladite bande 6 vers ladite machine d'emballage. Ce renvoi à 90° est réalisé de manière à permettre le déroulement de la bande 6 dans le sens de la chaîne d'emballage 2.In order to allow the feeding of the packaging machine, the supply device 1 comprises means 8 capable of performing a return of angle, preferably square, of said strip 6 to said packaging machine.

Thus, the supply device 1 may be arranged laterally with respect to the packaging line 2 and feed the packaging machine longitudinally.

Un avantage du dispositif d'approvisionnement 1 selon l'invention réside dans la mobilité de l'arbre 9 de sorte que son réglage transversal permet de corriger un éventuel décalage de la bande 6. De ce fait, le temps de correction du film est minimisé à la seule portion 11 de bande 6 située entre la sortie du dispositif d'approvisionnement 1 et l'entrée de la machine d'emballage.An advantage of the supply device 1 according to the invention lies in the mobility of the shaft 9 so that its transverse adjustment makes it possible to correct any offset of the strip 6.

Ces derniers peuvent se présenter sous la forme d'un couple vis/écrou comme visible sur la figure 3, formant ainsi une molette qu'il suffit de tourner pour ajuster latéralement le chariot 10, et par conséquent l'arbre 9. Ce système vis/écrou peut être disposé de manière à faire coopérer une vis solidaire du chariot 10 avec un trou 20 taraudé dans ledit châssis 3.The adjustment means 12 further comprise means 19 for controlling the adjustment. These can be in the form of a torque screw / nut as visible on the figure 3 , thus forming a wheel that can be rotated to adjust laterally the carriage 10, and therefore the shaft 9. This screw / nut system can be arranged to cooperate a screw secured to the carriage 10 with a threaded hole 20 in said frame 3.

Dans un mode de réalisation particulier, non représenté, les moyens de commande du réglage 19 peuvent être gradués et/ou automatisés de sorte que le décalage de la bande 6 peut être automatiquement détecté et compensé par un actionnement du couple vis/écrou, notamment sous l'action d'un moteur ou similaire.In a particular embodiment, not shown, the adjustment control means 19 can be graduated and / or automated so that the offset of the band 6 can be automatically detected and compensated by an actuation of the screw / nut torque, in particular under the action of an engine or the like.

Il convient de noter que le châssis 3 comprend des moyens 22 aptes à supporter une bobine 5 au cours de son déroulement. En particulier, ces moyens support 22 peuvent comprendre un bras articulé en rotation sur ledit châssis 3 de manière à basculer pour permettre la mise en place d'une bobine neuve ou de rechange.It should be noted that the frame 3 comprises means 22 adapted to support a coil 5 during its course. In particular, these support means 22 may comprise an arm articulated in rotation on said frame 3 so as to tilt to allow the introduction of a new or replacement spool.

L'invention concerne encore une chaîne 2, notamment d'emballage, comprenant une machine, réciproquement d'emballage, telle une thermoformeuse ou un operculeuse, alimentée en film par un dispositif d'approvisionnement 1 précédemment décrit. Ce type de chaîne est préférentiellement, mais non limitativement, utilisé dans le domaine de l'emballage alimentaire, mais peut-être utilisées dans l'imprimerie, le textile.The invention also relates to a chain 2, in particular packaging, comprising a machine, reciprocally packaging, such as a thermoformer or a sealing machine, fed with film by a supply device 1 previously described. This type of chain is preferably, but not exclusively, used in the field of food packaging, but may be used in printing, textile.
