Description

DISPOSITIF POUR LE DECOUPAGE ET LA SEPARATION DE FEUILLES EN PAPIER, CARTON OU MATIERES SEMBLABLESDEVICE FOR CUTTING AND SEPARATING SHEETS OF PAPER, CARDBOARD OR SIMILAR MATERIALS
Domaine techniqueTechnical area
La présente invention concerne un dispositif pour le découpage de feuilles en papier, carton ou matières semblables, le s dite s feuilles étant transformées en poses multiples et le dispositif précité étant muni d'une alimentation en feuilles, d'une platine de découpage, d'une station d'éjection des déchets, d'une station de réception, ainsi que d'un dispositif de séparation des poses.The present invention relates to a device for cutting sheets of paper, cardboard or similar materials, the so-called s sheets being transformed into multiple poses and the aforementioned device being provided with a sheet feed, a cutting plate, d '' a waste ejection station, a reception station, as well as a device for separating the poses.
Technique antérieurePrior art
Des dispositifs de découpage du genre précité sont connus et utilisés, entre autres, pour découper â l' emporte-pièce dans des feuilles en carton les formes (poses) correspondant au produit désiré, pour éjecter les déchets de découpage et pour acheminer lesdites poses vers une réception d'où ces dernières sont acheminées vers un dispositif assurant une opération ultérieure.Cutting devices of the aforementioned kind are known and used, inter alia, to cut with a cookie cutter in cardboard sheets the shapes (poses) corresponding to the desired product, to eject the cutting waste and to convey said poses to a reception from which these are sent to a device ensuring a subsequent operation.
Pour des raisons économiques, on découpe dans une seule feuille plusieurs poses qui, après le processus de découpage, restent liées les unes aux autres par les bords pour être tran sférées ainsi à la réception. Ce système comporte toutefois le désavantage que les découpes attachées doivent être séparées les unes des autres par un processus supplémentaire avant leur transformation ultérieure, par exemple en boîtes pliantes. Ceci s'effectue soit manuellement lors de l'introduction des découpes dans la machine de tra sformation subséquente ou alors â l'aide d'une machine de séparation des poses intercalée.For economic reasons, several blanks are cut from a single sheet which, after the cutting process, remain linked to each other by the edges so as to be transferred to the reception. However, this system has the disadvantage that the attached blanks must be separated from each other by an additional process before their further processing, for example into boxes folding. This is done either manually when the blanks are introduced into the subsequent processing machine or else using an interposed machine for separating the blanks.
Exposé de l'inventionStatement of the invention
Le but de la présente invention consiste à supprimer ce processus supplémentaire et â obtenir une séparation mécanique et, partant, la réception des découpes séparées. Cette mesure pourrait être effectuée avantageusement en étant accomplie conjointement à l'action d'un dispositif existant de la machine de découpage pour, ain si, ne devoir recourir qu'a un minimum de stations dans ladite machine de découpage.The object of the present invention is to eliminate this additional process and to obtain a mechanical separation and hence the reception of the separate cuts. This measurement could advantageously be carried out by being carried out in conjunction with the action of an existing device of the cutting machine so, therefore, having to have recourse to a minimum of stations in said cutting machine.
A cet effet, la . présente invention a pour objet un dispositif pour le découpage de feuilles en papier, carton ou matières semblables, les feuilles étant tran sformées en poses multiples, le dispositif précité étant muni d'une alimentation en feuilles, d'une platine de découpage, d'une station d'éjection des déchets et d'une station de réception, l'acheminement des feuilles étant prévu par un dispositif de transport approprié, caractérisé par le fait que la station de réception comporte un dispositif de séparation des poses.To this end, the. The present invention relates to a device for cutting sheets of paper, cardboard or similar materials, the sheets being transformed into multiple poses, the aforementioned device being provided with a sheet feed, a cutting plate, a waste ejection station and a reception station, the routing of the sheets being provided by an appropriate transport device, characterized in that the reception station comprises a device for separating the blanks.
Suivant une autre caractéristique, le dispositif de séparation des poses situé dans la station de réception comprend une partie supérieure, essentiellement mobile, dans le sens vertical, et une partie inférieure, la partie supérieure possédant des contre- parties selon la configuration des poses à séparer et la partie inférieure des barres de séparation correspondant aux bords des poses â séparer.According to another characteristic, the device for separating the blanks located in the reception station comprises an upper part, essentially movable, in the vertical direction, and a lower part, the upper part having counterparts according to the configuration of the blanks to be separated and the lower part of the separation bars corresponding to the edges of the blanks to be separated.
En outre, il est possible d'aménager, au-dessous des barres de séparation, des ponts de guidage destinés à guider les poses séparées. Pour assurer le mouvement vertical de la partie supérieure, celle-ci peut être fixée aux leviers pivotants au moyen de tiges de levage articulées, lesdits leviers étant pivotables verticalement dans les limites du parcours de levage de la partie supérieure. Le pivotement desdits leviers peut avantageusement être entraîné et commandé â partir d'un dispositif de transport. D 'après une autre caractéristique, la partie supérieure est pivotable dans le sen s vertical par une commande hydraulique.In addition, it is possible to arrange, below the dividing bars, guide bridges intended to guide the separate poses. To ensure the vertical movement of the upper part, it can be fixed to the pivoting levers by means of articulated lifting rods, said levers being pivotable vertically within the limits of the lifting path of the upper part. The pivoting of said levers can advantageously be driven and controlled from a transport device. According to another characteristic, the upper part is pivotable in the vertical direction by hydraulic control.

Meilleure manière de réaliser l'inventionBest way to realize the invention
La fig. 1 est purement schématique et représente uniquement la disposition générale. L'approvisionnement en feuilles 1 est conçu de telle façon qu'une pile 2 comportant les feuilles â découper peut être posée sur une palette 3 et, de ce fait, introduite directement dans le dispositif.Fig. 1 is purely schematic and represents only the general arrangement. The supply of sheets 1 is designed such that a stack 2 comprising the sheets to be cut can be placed on a pallet 3 and, therefore, introduced directly into the device.
Grâce à un dispositif de transport (non représenté) , c'est toujours la feuille supérieure 4 qui est emportée de la pile 2 est alignée de façon appropriée sur une table de marge 5 avant d'être acheminée vers le dispositif de transport 6. Ce dispositif 6 se compose, de façon connue, par exemple de chaînes de transport sans fin 7 destinées à saisir les bords avant des feuilles 4 de façon connue à l'aide de barres de pinces et de les tirer â l'intérieur de la machine. Le chiffre 8 a été attribué â la platine de découpage dans laquelle les feuilles 9 introduites sont découpées. Ces dernières feuilles sont ensuite tirées dans la station d'éjection des déchets 10 dans lequel les déchets ( 1 1 ) sont détachés de la feuille et interceptés par un récipient 12. La feuille qui, à ce stade, ne consiste plus qu'en une série de poses interconnectées, arrive ensuite dans la station de réception 13.Thanks to a transport device (not shown), it is always the top sheet 4 which is carried from the stack 2 is appropriately aligned on a margin table 5 before being conveyed to the transport device 6. This device 6 is made up, in a known way, for example of endless transport chains 7 intended to grip the front edges of the sheets 4 in a known way using pliers bars and to pull them inside the machine. The number 8 has been assigned to the cutting plate from which the sheets 9 inserted are cut. These last sheets are then pulled into the waste ejection station 10 in which the waste (1 1) is detached from the sheet and intercepted by a container 12. The sheet which, at this stage, consists only of a series of interconnected poses, then arrives at the receiving station 13.
Cette station 13 est aménagée de façon â permettre aux poses d'être réceptionnées les unes sur les autres sous forme d'une pile 14 sur la palette 15. Selon la présente invention, il est prévu d'aménager le dispositif de séparation des poses 16 au-dessus de la station de réception, respectivement à l'intérieur de cette dernière. Le fait de séparer les poses a pour con séquence la séparation de la feuille en différentes poses individuelles et la réception de celle-ci sous forme séparée sur la palette 15.This station 13 is arranged so as to allow the blanks to be received one on top of the other in the form of a stack 14 on the pallet 15. According to the present invention, provision is made for fitting the blanking device 16 above the receiving station, respectively inside the latter. The fact of separating the poses has as a consequence the separation of the sheet into different individual poses and the reception thereof in separate form on the pallet 15.
Le dispositif de séparation des poses se compose d'une partie supérieure 17 et d'une partie inférieureThe pose separation device consists of an upper part 17 and a lower part
18 ainsi qu'il ressort de la fig. 2.18 as shown in FIG. 2.
La p artie inférieure 18 est solidaire de l'entité du dispositif grâce aux supports 1 9. A l'intérieur du cadre 20, ont été aménagés les barres de séparation 21 dont la disposition correspond aux bords des poses à séparer. Dans le cas représenté, chaque feuille est séparée en huit poses rectangulaires.The lower part 18 is integral with the entity of the device thanks to the supports 1 9. Inside the frame 20, the separation bars 21 have been arranged, the arrangement of which corresponds to the edges of the blanks to be separated. In the case shown, each sheet is separated into eight rectangular poses.
Dans sa position de travail, la partie supérieure 17 est disposée plus ou moins parallèlement â la partie inférieure (voir fig. 3) et possède des contre-parties 22 qui dépassent la partie 17 dans le sen s descendant et présente une configuration extérieure plus ou moins identique â celle des poses à séparer mais en aucun cas plus petite que lesdites poses. La forme des barres de séparation 21 et des contre-parties 22 représentés par la figure 2 est illustrée comme un simple rectangle. Toutefois, ladite forme peut aussi être très compliquée selon la pose désirée.In its working position, the upper part 17 is arranged more or less parallel to the lower part (see fig. 3) and has counterparts 22 which protrude from the part 17 in the downward direction and has an external configuration more or less identical to that of the poses to be separated but in no case smaller than said poses. The shape of the separation bars 21 and the counterparts 22 shown in FIG. 2 is illustrated as a simple rectangle. However, said form can also be very complicated depending on the desired pose.
le fonctionnement du dispositif de séparation des poses est expliqué à l'aide de la fig. 3. La partie supérieure 17 se trouve en position relevée de telle sorte que le dispositif de transport puisse tirer les feuilles avec les poses 23 et 24 rattachées jusqu'à ce que les bords des poses 33 soient situés au-dessus des barres de séparation 21 respectives. Ensuite, la partie supérieure est abaissée, après quoi les contre-parties 22 poussent les poses 23 et 24 vers le bas â travers la partie inférieure 18, ce qui a pour conséquence la séparation des poses le long des bords de poses 33. Les poses ainsi séparées tombent pour être réceptionnées sur la palette 15 en formant une pile 14. En prenant leur départ aux barres de séparation 21 , des ponts de guidage se prolongent vers le bas comme illustré de façon agrandie par la fig. 4. Ces ponts de guidage 25 impriment aux poses séparées un certain guidage jusqu 'au niveau de la pile 14 située au-dessous, de sorte qu'il en résulte un réception ordrêe.the operation of the blanking device is explained using fig. 3. The upper part 17 is in the raised position so that the transport device can pull the sheets with the poses 23 and 24 attached until the edges of the poses 33 are located above the dividing bars 21 respective. Then, the upper part is lowered, after which the counterparts 22 push the poses 23 and 24 downward through the lower part 18, which results in the separation of the poses along the edges of the poses 33. The poses thus separated fall to be received on the pallet 15 forming a stack 14. Taking their departure from the separation bars 21, the guide bridges extend downward as illustrated in an enlarged manner in FIG. 4. These guide bridges 25 give the separate poses some guidance up to the level of the stack 14 located below, so that this results in an orderly reception.
Après la séparation des poses ain si décrite, la partie supérieure 17 est de nouveau relevée pour libérer la voie de la feuille suivante à introduire.After the separation of the poses ain if described, the upper part 17 is raised again to free the way of the next sheet to be introduced.
Le mouvement vertical de la partie supérieure peut être effectué, en principe, par n'importe quelle technique d'entraînement. La fig. 5 représente schêmatiquement deux exemples d'exécution de la technique préférée. Une tige de relevage 26 est fixée sur chaque coins de la partie 17 et est rattachée â son extrémité supérieure, par l'intermédiaire d'un axe 27, au moyen d'un levier pivotant articulé 29. Par le pivotement ascendant et descendant du levier pivotant, la tige de relevage 26 et, partant, la partie supérieure 17 sont relevées et abaissées avec la cadence voulue.The vertical movement of the upper part can, in principle, be carried out by any training technique. Fig. 5 schematically represents two examples of execution of the preferred technique. A lifting rod 26 is fixed to each corner of the part 17 and is attached to its upper end, by means of an axis 27, by means of an articulated pivoting lever 29. By the upward and downward pivoting of the lever pivoting, the lifting rod 26 and, consequently, the upper part 17 are raised and lowered at the desired rate.
Le professionnel se rend aisément compte que le mouvement vertical de la partie 17 peut aus si être assuré avantageusement par d'autres dispositif s tels que, par exemple, des cylindres hydrauliques reliés directement aux tiges de relevage 26 où aux leviers pivotants 28.The professional easily realizes that the vertical movement of the part 17 can also be provided advantageously by other devices such as, for example, hydraulic cylinders connected directly to the lifting rods 26 or to the pivoting levers 28.
En ce qui concerne la fig. 2, il convient d'ajouter que, dans la zone des contre-parties 22, on a prévu des dégagements traversants 34 qui permettent le passage de l'air lorsque la partie supérieure 17 est abaissée sur les poses non encore séparées et que les poses, séparées dans une phase ultérieure, se détachent de la partie supérieure vers le bas. Regarding fig. 2, it should be added that, in the area of the counterparts 22, provision has been made for through clearances 34 which allow the passage of air when the upper part 17 is lowered onto the blanks not yet separated and the blanks , separated in a later phase, detach from the top down.
