Description

L'invention concerne les machines de fabrication d'enveloppes ou de pochettes, et plus particulièrement d'enveloppes ou de pochettes à fenêtre.The invention relates to machines for manufacturing envelopes or pouches, and more particularly envelopes or pouches with windows.

Les machines connues destinées à fabriquer de telles enveloppes ou de telles pochettes sont composées de "stations" dans chacune desquelles sont effectuées une ou plusieurs opérations de fabrication, les stations étant parcourues séquentiellement par le produit destiné à la constitution des enveloppes.The known machines intended for manufacturing such envelopes or such pockets are composed of "stations" in each of which one or more manufacturing operations are carried out, the stations being traversed sequentially by the product intended for constituting the envelopes.

De manière générale, ces enveloppes ou pochettes, qui pour la commodité de l'exposé seront désignées de manière générique par le terme "enveloppes" dans la suite, sont réalisées au moyen de feuilles individuelles obtenues par découpage de tronçons sectionnés dans une bande de matériau initialement enroulée autour d'un tambour en constituant une bobine.In general, these envelopes or pouches, which for the sake of convenience will be designated generically by the term "envelopes" in the following, are produced by means of individual sheets obtained by cutting sections cut from a strip of material. initially wound around a drum constituting a coil.

Les machines dédiées à la fabrication d'enveloppes de dimensions données ne sont adaptables à la fabrication d'enveloppes de dimensions différentes que par des modifications relativement longues et complexes. En revanche, il n'est pas exclu, et il peut être intéressant, d'utiliser une même machine pour réaliser des enveloppes de mêmes dimensions mais comportant une fenêtre de forme, de dimensions, ou d'emplacement différents, ce qui ne nécessite que des modifications relativement minimes sur la machine ; néanmoins ces modifications minimes nécessitent un certain temps au cours duquel le fonctionnement de la machine doit être interrompu ; de manière plus classique, les stations dans lesquelles sont réalisées les fenêtres comportent des outils spécifiques qu'il est parfois nécessaire d'entretenir, de réparer, ou de changer, alors que les autres stations ne nécessitent simultanément pas d'intervention ; les opérations d'entretien, de réparation, ou de changement d'outil(s) nécessitent également un temps qui est perdu pour la fabrication.Machines dedicated to the manufacture of envelopes of given dimensions are only adaptable to the manufacture of envelopes of different dimensions by relatively long and complex modifications. On the other hand, it is not excluded, and it may be advantageous, to use the same machine to produce envelopes of the same dimensions but having a window of different shape, dimensions, or location, which requires only relatively minor modifications to the machine; nevertheless, these minimal modifications require a certain time during which the operation of the machine must be interrupted; more conventionally, the stations in which the windows are made include specific tools that it is sometimes necessary to maintain, repair, or change, while the other stations do not simultaneously require intervention; the operations maintenance, repair, or change of tool (s) also require time which is lost for manufacturing.

L'invention a pour but de remédier à ces inconvénients en créant une machine permettant de poursuivre la fabrication d'enveloppes alors que leurs stations de réalisation de fenêtres sont hors fonctionnement.The object of the invention is to remedy these drawbacks by creating a machine enabling the manufacture of envelopes to continue while their window production stations are out of operation.

L'invention concerne donc une machine de fabrication d'enveloppes comportant une suite de stations comprenant des stations de réalisation de fenêtres dans une bande ou dans des feuilles individuelles, ces stations de réalisation de fenêtres constituant un appareillage de réalisation de fenêtres à l'intérieur duquel est défini un trajet prédéterminé pour la bande ou les feuilles sur lequel cette bande ou ces feuilles sont mises en contact avec des outils de réalisation de fenêtres, depuis une station de découpage de fenêtres jusqu'à une station de découpage de forme, machine caractérisée en ce que le long de l'appareillage de réalisation de fenêtres, est défini un second trajet pour la bande ou les feuilles sur lequel la bande ou les feuilles sont maintenues hors de contact avec les outils de réalisation de fenêtres, ledit trajet prédéterminé et ledit second trajet comportent un début et une fin communs, et le début des trajets est matérialisé par un dispositif de commutation mécanique dirigeant la bande ou les feuilles sélectivement sur ledit trajet prédéterminé ou sur ledit second trajet.The invention therefore relates to a machine for making envelopes comprising a series of stations comprising stations for making windows in a strip or in individual sheets, these stations for making windows constituting an apparatus for making windows inside. from which a predetermined path is defined for the strip or sheets on which this strip or these sheets are brought into contact with window making tools, from a window cutting station to a shape cutting station, machine characterized in that along the window making apparatus is defined a second path for the strip or sheets on which the strip or sheets are kept out of contact with the window making tools, said predetermined path and said second journey have a common start and end, and the beginning of the journeys is indicated by a disp positive mechanical switching directing the strip or sheets selectively on said predetermined path or on said second path.

Il en résulte que l'invention permet très simplement de sélectionner la fabrication de l'un ou l'autre type d'enveloppes, et ainsi d'effectuer des interventions sur la partie de la machine qui réalise les fenêtres sans interrompre la fabrication d'enveloppes.As a result, the invention very simply makes it possible to select the manufacture of one or the other type of envelopes, and thus to carry out interventions on the part of the machine which produces the windows without interrupting the manufacture of envelopes.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'une forme de réalisation de l'invention donnée à titre d'exemple non limitatif et illustrée par les dessins annexés dans lesquels :

  • la figure 1 montre schématiquement une machine connue, et
  • la figure 2 montre schématiquement une machine modifiée selon l'invention.
Other characteristics and advantages of the invention will emerge from the description which follows of an embodiment of the invention given by way of nonlimiting example and illustrated by the appended drawings in which:
  • FIG. 1 schematically shows a known machine, and
  • Figure 2 schematically shows a modified machine according to the invention.

La machine de fabrication d'enveloppes (ou de pochettes) connue, représentée sur la figure 1 comporte des stations 1-14 disposées à la suite l'une de l'autre, adaptées chacune à réaliser une ou plusieurs opérations de fabrication sur le produit destiné à la constitution des enveloppes, se présentant initialement sous la forme d'une bande de papier provenant d'une bobine d'alimentation et transportée en continu ou sous la forme de feuilles individuelles transportées l'une à la suite de l'autre, par des cylindres de transport ; dans l'exemple représenté, le produit se présente sous la forme d'une bande de papier B jusqu'à une station de séparation qui découpe dans la bande, les feuilles individuelles destinées à constituer les enveloppes.The known machine for making envelopes (or pouches), represented in FIG. 1, comprises stations 1-14 arranged one after the other, each adapted to carry out one or more manufacturing operations on the product. intended for constituting envelopes, initially in the form of a strip of paper coming from a supply reel and transported continuously or in the form of individual sheets transported one after the other, by transport cylinders; in the example shown, the product is in the form of a strip of paper B up to a separation station which cuts from the strip, the individual sheets intended to constitute the envelopes.

Ces stations qui se suivent de telle sorte que la sortie de l'une soit reliée à l'entrée de la suivante sont, dans l'ordre (qui est celui dans lequel elles sont parcourues par le produit jusqu'à son aboutissement à l'état d'enveloppe), une station d'impression 1 (ici flexographique), une station de découpage 2 de fenêtres, une station d'encollage et d'application 3 de matière de fenêtres, une station de découpage 4 de la forme, une station de pliage 5 de pattes latérales, une station de collage 6 de pattes latérales, une station de séparation 7 de la bande en feuilles d'enveloppe individuelles, une station de pliage 8 de pattes de fond, une station de pliage 9 de pattes latérales extérieures, une station d'étageage 10, une station de gommage 11 de pattes de fermeture (gommage à la dextrine, ou au latex, ou à la gomme d'adhésion), une station de séchage 12, une station de margeage 13, et une station de réception 14.These stations which follow each other so that the output of one is connected to the input of the next are, in order (which is the one in which they are traversed by the product until its completion at the envelope state), a printing station 1 (here flexographic), a window cutting station 2, a sizing and application station 3 of window material, a shape cutting station 4, a folding station 5 for side tabs, a bonding station 6 for side tabs, a station for separating the strip into individual envelope sheets, a station for folding 8 bottom tabs, a station for folding 9 outer side legs, a leveling station 10, a gumming station 11 of closing tabs (gum with dextrin, or latex, or adhesion gum), a drying station 12, a margining station 13 , and a receiving station 14.

L'ensemble des stations de réalisation de fenêtres, à savoir la station de découpage 2 de fenêtres, la station d'encollage et d'application 3 de matière de fenêtres, et la station de découpage 4 de la forme, constitue un appareillage de réalisation de fenêtres à l'intérieur duquel est défini le trajet pour la bande sur lequel cette bande est mise en contact avec des outils de réalisation de fenêtres, depuis la station de découpage 2 de fenêtres jusqu'à la station de découpage 4 de forme.The set of window production stations, namely the window cutting station 2, the sizing and application station 3 of window material, and the shape cutting station 4, constitutes a production apparatus. of windows inside which the path for the strip is defined on which this strip is brought into contact with tools for making windows, from the window cutting station 2 to the shape cutting station 4.

Plus précisément, la station de découpage de fenêtres comporte des outils pour découper dans la bande, une ouverture rectangulaire à coins arrondis.More specifically, the window cutting station includes tools for cutting from the strip, a rectangular opening with rounded corners.

La station d'encollage et d'application 3 de matière de fenêtres comporte un tambour portant une bobine 31 de matière de fenêtres sous la forme d'une bande d'un film de matière plastique transparent ; elle comporte aussi des outils de sectionnement de la bande de matière plastique en rectangles de dimensions supérieures à celles de l'ouverture et des outils d'encollage, sur une face, de la zone proche du pourtour de chaque section de bande de fenêtre qui a été découpée ; elle comporte également des outils d'application de la face partiellement encollée de chaque section de bande de fenêtre contre une face de la bande B destinée à constituer les enveloppes, de telle manière que le centre de la section de bande de fenêtre et celui de l'ouverture coïncident au moins approximativement et que leurs côtés correspondants respectifs soient sensiblement parallèles.The sizing and application station 3 for window material comprises a drum carrying a coil 31 of window material in the form of a strip of a film of transparent plastic material; it also includes tools for cutting the strip of plastic material into rectangles of dimensions larger than those of the opening and gluing tools, on one side, for the area close to the periphery of each section of window strip which has been cut; it also includes tools for applying the partially glued side of each window strip section against one side of the strip B intended to constitute the envelopes, such that the center of the window strip section and that of the window the opening coincide at least approximately and that their respective corresponding sides are substantially parallel.

La station de découpage 4 de la forme étant du type à outil(s) de coupe rotative ou encore du type à couteaux à ailettes, est, selon une caractéristique avantageuse de l'invention, adaptée à recevoir des couteaux rotatifs flexibles.The cutting station 4 of the form being of the type with rotary cutting tool (s) or even of the type with wing knives, is, according to an advantageous characteristic of the invention, adapted to receive flexible rotary knives.

Les autres stations sont munies d'outils appropriés à leur fonction respective, et par exemple la station de séchage 12 est munie de conduits 121 d'arrivée d'air chaud dont l'extrémité libre est équipée d'une buse de soufflage 122.The other stations are provided with tools suitable for their respective function, and for example the drying station 12 is provided with ducts 121 for the arrival of hot air, the free end of which is equipped with a blowing nozzle 122.

Selon l'invention, afin de rendre possible la poursuite de la réalisation d'enveloppes alors que les stations de réalisation de fenêtres sont hors fonctionnement, par exemple tandis que l'on entretient ou que l'on change les outils dont elles sont équipées, on crée le long de l'appareillage de réalisation de fenêtres, un second trajet pour la bande B ou les feuilles, sur lequel la bande ou les feuilles sont maintenues hors de contact avec les outils de réalisation de fenêtre (outils de découpage, d'encollage, d'application de feuilles de fenêtre, de découpage de la forme, notamment), ce second trajet et le premier trajet le long duquel la bande est mise en contact avec des outils de réalisation de fenêtres comportant un début et une fin communs, et le début des deux trajets étant matérialisé par un dispositif de commutation mécanique dont seul l'emplacement, ici juste à la sortie de la station d'impression 1, est schématisé en 15 sur la figure 2, dirigeant la bande ou les feuilles sélectivement sur le premier ou le second trajet.According to the invention, in order to make it possible to continue making envelopes while the window production stations are out of operation, for example while the tools with which they are being maintained or changed, a second path is created along the window production equipment for the strip B or the sheets, on which the strip or the sheets are kept out of contact with the window production tools (cutting tools, sizing, application of window sheets, cutting of the shape, in particular), this second path and the first path along which the strip is brought into contact with window production tools having a common start and end, and the start of the two paths being materialized by a mechanical switching device whose only location, here just at the exit of the printing station 1, is shown diagrammatically at 15 in FIG. 2, directing the ba nde or the leaves selectively on the first or the second path.

Afin de transporter la bande ou les feuilles le long de ce second trajet sur lequel celles-ci sont maintenues hors de contact avec les outils de réalisation de fenêtre, sont disposés des cylindres 16 de transport de cette bande ou de ces feuilles, avec lesquels celles-ci sont mises en contact. De préférence, ce second trajet passe à la partie inférieure de l'appareillage de réalisation de fenêtres, voire même sous celui-ci (station de découpage 2 de fenêtres, station d'encollage et d'application 3 de matière de fenêtres, et station de découpage 4 de la forme).In order to transport the strip or the sheets along this second path on which these are kept out of contact with the window making tools, there are arranged cylinders 16 for transporting this strip or these sheets, with which these are brought into contact. Preferably, this second path passes to the lower part of the window production apparatus, or even under it (window cutting station 2, gluing and application station 3 of window material, and station cutting 4 of the shape).

Le dispositif de commutation mécanique est un dispositif d'accouplement et de désaccouplement, par exemple à crabots, ici intercalé à la sortie de la station d'impression 1 mais pouvant l'être également entre cette sortie et l'entrée de la station de découpage 2 de fenêtres par le trajet pour la réalisation de fenêtres, destiné à transmettre un mouvement sur le premier ou le second trajet à cette station, et à interrompre ce mouvement, sélectivement.The mechanical switching device is a coupling and uncoupling device, for example with dogs, here interposed at the output of the printing station 1 but can also be between this output and the input of the cutting station 2 of windows by the path for the realization of windows, intended to transmit a movement on the first or the second path to this station, and to interrupt this movement, selectively.

Un dispositif de commutation mécanique pouvant aussi être un dispositif d'accouplement et de désaccouplement à crabots est également prévu sur la station d'encollage et d'application 3 de matière de fenêtres pour transmettre un mouvement à cette station et interrompre la transmission de ce mouvement, sélectivement.A mechanical switching device which can also be a clutch coupling and uncoupling device is also provided on the gluing and application station 3 of window material to transmit a movement to this station and to interrupt the transmission of this movement. , selectively.

Il en est de même en ce qui concerne la station de découpage 4 de la forme.It is the same with regard to the cutting station 4 of the shape.

Ainsi, il suffit d'un simple décrabotage et d'un re-crabotage pour pouvoir régler, entretenir ou changer les outils de fabrication de fenêtres tout en continuant de produire des enveloppes (ou des pochettes) sur la même machine en "temps masqué",

  • par désolidarisation du mouvement sur le premier trajet dans la station de découpage 2 de fenêtres,
  • par désolidarisation du mouvement sur le premier trajet dans la station d'encollage et d'application 3 de matière de fenêtres,
  • par désolidarisation du mouvement sur le premier trajet dans la station d'outils de format 4.
Thus, it suffices with a simple declutching and a re-clutching in order to be able to adjust, maintain or change the window manufacturing tools while continuing to produce envelopes (or pouches) on the same machine in "masked time" ,
  • by separating the movement on the first path in the window cutting station 2,
  • by separating the movement on the first path in the gluing and application station 3 of window material,
  • by separating the movement on the first path in the format 4 tool station.

L'invention peut aisément être appliquée aux machines existantes simplement en leur ajoutant les dispositifs de commutation mécanique et les cylindres 16 de transport aux emplacements appropriés.The invention can easily be applied to existing machines simply by adding to them the mechanical switching devices and the transport cylinders 16 at the appropriate locations.

Bien entendu, cette invention n'est pas limitée à la forme de réalisation ci-dessus décrite et représentée, et on pourra en prévoir d'autres formes sans sortir de son cadre.Of course, this invention is not limited to the embodiment described above and shown, and other forms can be provided without departing from its scope.
