Description

Le domaine de l'invention est la décortication de feuilles prédécoupées pour former des boîtes, telles qu'utilisées pour contenir des médicaments, des chocolats et autres produits alimentaires ou non.The field of the invention is the decortication of pre-cut sheets to form boxes, as used to contain drugs, chocolates and other food products or not.

Dans le métier, on parle d'ateliers de formes de découpe, de « formistes », la décortication consistant, à partir d'une feuille rectangulaire dans laquelle les six côtés ou parties de côté destinés à former une boîte parallélépipédique ont été tracés et prédécoupés, à enlever les parties de la feuille non utiles pour former la boîte et qu'on appelle « déchets » ou « chutes ». Les feuilles en question sont généralement des feuilles en carton, mais il peut s'agir d'autres matières, y compris métalliques, pour réaliser des boîtes.In the art, we speak of cutting forms, "formists", decortication consisting of a rectangular sheet in which the six sides or side parts intended to form a parallelepiped box have been drawn and pre-cut , to remove the parts of the sheet that are not useful for forming the box and that are called "waste" or "falls". The sheets in question are generally cardboard sheets, but they may be other materials, including metal, to make boxes.

Actuellement, pour procéder à cette décortication, ou extraction des déchets, on utilise une planche percée servant de gabarit d'évacuation, sur laquelle on pose la feuille à décortiquer, et des pointes supérieures et des contre-pointes inférieures pincent les déchets, donc prédécoupés, à travers les orifices de la planche gabarit avant de les guider vers le bas dans une descente d'évacuation automatisée pouvant comprendre un tapis, ou un bac, ou une trémie d'aspiration...Currently, to proceed with this decortication, or extraction of waste, is used a pierced board serving as a clearance template, on which the sheet to be peeled, and upper tips and lower counterpots pinch the waste, so pre-cut through the orifices of the template board before guiding them downwards in an automated discharge chute that may include a mat, or a tray, or a suction hopper ...

Les pointes supérieures sont disposées sur un châssis ou des lattes qui évoluent entre une position haute et une position basse de poussée. De même, les contre-pointes sont aussi disposées sur un châssis ou des lattes qui évoluent entre une position basse et une position haute de pincement. En effet, les contre-pointes sont montées dans des étuis sur ressort pour assurer le pincement des déchets. Ces contre-pointes sont donc assez complexes et relativement onéreuses et leur positionnement précis assez délicat, la précision étant requise du fait de la rapidité des processus de décortication qui peuvent atteindre des vitesses de 8000 feuilles à l'heure.The upper tips are arranged on a frame or slats that move between a high position and a low thrust position. Similarly, the counterspikes are also arranged on a frame or slats that move between a low position and a high pinch position. Indeed, the counterspikes are mounted in cases on spring to ensure the pinching of waste. These counter spikes are therefore rather complex and relatively expensive and their precise positioning rather delicate, precision being required because of the speed of decortication processes that can reach speeds of 8000 sheets per hour.

Généralement, les contre-pointes inférieures sont positionnées et leur positionnement ajusté manuellement, ce qui provoque une perte de temps coûteuse, sans parler des arrêts de production.Generally, the lower counterspikes are positioned and their positioning adjusted manually, which causes a costly waste of time, not to mention production stops.

Parfois, on monte les contre-pointes de manière mécanisée et au laser, mais c'est une source de dépenses supplémentaires en pièces immobilisées qui ne vaut la peine que pour des opérations de découpe assez répétitives. En tout état de cause, un ajustage subséquent d'une contre-pointe, au cas où un déchet ne tombe pas bien, est impossible à moindre coût.Sometimes the counter-points are mechanically and laser-mounted, but it is a source of additional expenditure on immobilized parts that is only worthwhile for quite repetitive cutting operations. In any case, a subsequent adjustment of a tailstock, in case a waste does not fall well, is impossible at a lower cost.

L'invention de la présente demande vise à éliminer tous les problèmes de coût présentés ci-dessus.The invention of the present application aims at eliminating all the cost problems presented above.

À cet effet, l'invention de la présente demande concerne une platine support d'au moins une contre-tige de pincement et d'évacuation de déchets de feuilles prédécoupées pour machine de formes de découpe, comprenant deux paliers supérieur et inférieur de guidage de la contre-tige, les deux paliers étant fixés l'un à l'autre par des entretoises, la contre-tige étant montée coulissante dans deux orifices de réception respectivement ménagés dans les deux paliers au droit l'un de l'autre, la contre-tige comportant, sous le palier supérieur, une bague d'appui contre la face inférieure du palier supérieur et un ressort de compression entourant la contre-tige en appui contre la bague d'appui et le palier inférieur, la platine étant agencée pour être montée sur un châssis inférieur de la machine agencé pour évoluer entre une position basse et une position haute.To this end, the invention of the present application relates to a support plate of at least one counter-pin for pinching and evacuation of pre-cut sheet waste for a cutting machine, comprising two upper and lower guide bearings of the counter-rod, the two bearings being fixed to one another by spacers, the counter-rod being slidably mounted in two receiving orifices respectively formed in the two bearings in line with each other, the counter-rod comprising, under the upper bearing, a bearing ring against the lower face of the upper bearing and a compression spring surrounding the counter-rod bearing against the bearing ring and the lower bearing, the plate being arranged to be mounted on a lower frame of the machine arranged to move between a low position and a high position.

La platine de l'invention est d'une très grande simplicité et d'un coût très bas. La contre-tige, qui est une simple tige, est bloquée en position haute contre le palier supérieur par sa bague d'appui, en position basse, par cette même bague d'appui contre le ressort en appui contre le palier inférieur. Le ressort libre autour de la contre-tige est parfaitement accessible à un opérateur.The plate of the invention is of great simplicity and a very low cost. The counter rod, which is a single rod, is locked in the upper position against the upper bearing by its support ring, in the low position, by the same bearing ring against the spring bearing against the lower bearing. The free spring around the counter rod is perfectly accessible to an operator.

De préférence, la platine comporte plusieurs contre-tiges, toutes montées de la même manière dans deux orifices correspondants des deux paliers.Preferably, the plate comprises several counter rods, all mounted in the same way in two corresponding holes of the two bearings.

Avantageusement, les orifices de réception de la contre-tige, ou des contre-tiges, ont été percés au laser et par ordinateur.Advantageously, the receiving ports of the counter-rod, or counter-rods, have been laser drilled and computer.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée de la platine de l'invention, en référence au dessin en annexe, sur lequel :

  • la figure 1 est une vue schématique d'une machine de formes de découpe ;
  • la figure 2 est une vue de face simplifiée d'un module de décortication de la machine de la figure 1 et
  • la figure 3 est une vue en perspective de la platine de l'invention équipant le module de la figure 2.
The invention will be better understood with the aid of the following description of a preferred embodiment of the stage of the invention, with reference to the appended drawing, in which:
  • the figure 1 is a schematic view of a machine of cutting shapes;
  • the figure 2 is a simplified front view of a decortication module of the machine of the figure 1 and
  • the figure 3 is a perspective view of the plate of the invention equipping the module of the figure 2 .

La machine de formes de découpe de la figure 1 comporte, de la droite vers la gauche, un module de découpe 1, le module de décortication 2 et, ici, un module séparateur de poses 3.The cutting shapes machine of the figure 1 comprises, from the right to the left, a cutting module 1, the decortication module 2 and, here, a separator module 3.

Ces modules sont bien connus de l'homme du métier et ils ne seront pratiquement pas décrits plus avant, tout du moins en ce qui concerne les deux modules 1 et 3 entourant le module de décortication 2. Toutefois, le module de découpe 1 comporte des couteaux qui prédécoupent à la pression une feuille, généralement en carton, pour pouvoir, après en avoir enlevé les portions non utiles dans le module de décortication 2, être pliée en un conteneur parallélépipédique destiné à contenir des produits en vrac ou non.These modules are well known to those skilled in the art and they will be practically not described further, at least as regards the two modules 1 and 3 surrounding the decortication module 2. However, the cutting module 1 comprises knives which pre-cut at the pressure a sheet, generally cardboard, to be able, after having removed the portions not useful in the decortication module 2, to be folded into a parallelepiped container for containing products in bulk or not.

Le module de décortication 2 comporte montés dans un râtelier 4, un châssis supérieur de poussée 5 portant des tiges de poussée 6 dirigées vers le bas, un châssis inférieur de pincement 7 portant des contre-tiges de pincement 8, 9 dirigées vers le haut et une planche percée de décortication 10.The decortication module 2 comprises mounted in a rack 4, an upper support frame 5 carrying pushing rods 6 directed downwards, a lower clamping frame 7 carrying pinch-off rods 8, 9 directed upwards and a breakthrough decortication board 10.

Pour une bonne compréhension de la platine de l'invention décrite ci-après, la description du fonctionnement du module de décortication 2 n'est pas inutile.For a good understanding of the plate of the invention described below, the description of the operation of the decortication module 2 is not useless.

On fait monter le châssis 7 jusqu'à ce que les contre-tiges 8, 9 arrivent presque au niveau de la paroi inférieure 11 de la planche 10.The frame 7 is raised until the counter-rods 8, 9 arrive almost at the level of the bottom wall 11 of the board 10.

Une feuille 14, précédemment prédécoupée dans le module 1, arrive sur la paroi supérieure 12 de la planche 10 pour y être « décortiquée ». À cet effet, on a ménagé dans la planche 10 des ouvertures de repérage 13 correspondant aux portions non utiles de la feuille. La feuille est donc positionnée sur la planche dans une superposition très précise, la planche 10 devant servir de gabarit d'évacuation de ces portions non utiles (chutes ou déchets). On fait descendre le châssis 5 dont les tiges 6 viennent au contact de la feuille 14 et on fait monter encore le châssis 7 dont les contre-tiges 8, 9, montées sur ressort, viennent, à travers les ouvertures 13 de la planche 10, pincer les portions de la feuille 14 à décortiquer entre elles et les tiges de poussée 6 du châssis supérieur 5, les ressorts des contre-tiges 8, 9 étant alors comprimés, avant que, sous la poussée des tiges 6, les portions inutiles de la feuille 14 s'en détachent et, après la descente du châssis 7, soient évacuées à travers le châssis 7 ici dans un bac d'évacuation 15.A sheet 14, previously pre-cut in the module 1, arrives on the upper wall 12 of the board 10 to be "shelled". For this purpose, there are provided in the plate 10 locating openings 13 corresponding to the non-useful portions of the sheet. The sheet is therefore positioned on the board in a very precise superposition, the board 10 to serve as template for evacuation of these non-useful portions (falls or waste). The chassis 5, whose rods 6 come into contact with the sheet 14, is lowered and the frame 7 is further mounted, the spring-loaded counter-rods 8, 9 of which come through the openings 13 of the plate 10. pinch the portions of the sheet 14 to be peeled between them and the push rods 6 of the upper frame 5, the springs of the rods 8, 9 then being compressed, before, under the pressure of the rods 6, the useless portions of the sheet 14 are detached and, after the descent of the frame 7, are evacuated through the frame 7 here in a drain tray 15.

Les contre-tiges de pincement du châssis inférieur 7 sont de deux types, mais compatibles entre eux. Sont montées dessus des contre-tiges 8 de l'art antérieur, avec ressort intégré dans un étui 16, et des contre-tiges 9 de la platine 20 de l'invention qui va maintenant être décrite.The counter-pinch rods of the lower frame 7 are of two types, but compatible with each other. Mounted against the rods 8 of the prior art, with spring integrated in a case 16, and against-rods 9 of the plate 20 of the invention will now be described.

La platine 20, qui ne porte qu'une partie des contre-tiges de poussée du châssis 7, présente l'avantage d'un réglage et d'une adaptation intéressante aux feuilles à décortiquer, adaptation difficile et onéreuse avec le reste du châssis de poussée.The plate 20, which carries only part of the thrust rods against the frame 7, has the advantage of an adjustment and an interesting adaptation to the sheets to be peeled, difficult and expensive adaptation with the rest of the frame of thrust.

La platine 20 comporte un palier supérieur 21 et un palier inférieur 22, tous deux de guidage, dans l'exemple illustré sur la figure 3, de deux contre-tiges 23, 24 et de plus de deux dans l'exemple illustré sur la figure 2.The plate 20 comprises an upper bearing 21 and a lower bearing 22, both of which, in the example illustrated on FIG. figure 3 , against two rods 23, 24 and more than two in the example shown on the figure 2 .

Il s'agit ici de deux plaques s'étendant parallèlement l'une à l'autre et, la platine 20 une fois montée sur le châssis 7, également parallèlement à la planche 10. Les deux paliers sont fixés l'un à l'autre ici par deux entretoises 29, 30.This is two plates extending parallel to each other and the plate 20 once mounted on the frame 7, also parallel to the board 10. The two bearings are fixed one to the other here by two spacers 29, 30.

Les deux contre-tiges 23, 24 sont montées coulissantes respectivement dans deux paires d'orifices 25, 26 et 27, 28 respectivement percés dans les deux paliers au droit l'un de l'autre. Ici, les orifices 25-28 ont été percés au laser et par ordinateur.The two counter-rods 23, 24 are slidably mounted respectively in two pairs of orifices 25, 26 and 27, 28 respectively pierced in the two bearings in line with each other. Here, ports 25-28 were laser and computer drilled.

Chaque contre-tige comporte une bague 31, en forme de bourrelet rapporté sur la contre-tige ou d'excroissance en saillie hors de la contre-tige, destinée à venir en appui contre la face inférieure 32 du palier supérieur 21. Un ressort de compression 33 enveloppe chaque contre-tige pour venir en appui, en partie supérieure, contre la bague 31 et, en partie inférieure, contre la face supérieure 34 du palier inférieure 22. Ainsi, chaque contre-tige est montée coulissante dans ses deux orifices de guidage 25, 26 et 27, 28 entre une position haute, où elle est bloquée par sa bague 31 en appui contre le palier supérieur 21 et, en position basse, par sa bague 31 en appui contre la spire haute 35 de son ressort à l'état comprimé, en appui contre le palier inférieur 22 par sa spire basse 36. Chaque contre-tige, par une portion 37, fait saillie vers le haut hors du palier supérieur 21, pour pouvoir pincer les portions de la feuille 14 à décortiquer contre les tiges de poussée 6 du châssis supérieur 5, les portions de contre-tige 37 étant destinées à être introduites dans les ouvertures de repérage 13 de la planche 10.Each counter-rod has a ring 31, in the form of a bead attached to the counter-rod or protruding protruding from the counter-rod, intended to bear against the lower face 32 of the upper bearing 21. A spring compression 33 envelopes each counter-rod to bear, in the upper part, against the ring 31 and, in the lower part, against the upper face 34 of the lower bearing 22. Thus, each counter-rod is slidably mounted in its two orifices. guide 25, 26 and 27, 28 between a high position, where it is blocked by its ring 31 bearing against the upper bearing 21 and, in the lower position, by its ring 31 bearing against the high turn 35 of its spring to compressed state, bearing against the lower bearing 22 by its low turn 36. Each counter-rod, by a portion 37, protrudes upwardly from the upper bearing 21, to pinch the portions of the sheet 14 to be peeled against push rods e 6 of the upper frame 5, the counterbore portions 37 being intended to be introduced into the locating apertures 13 of the board 10.

La platine 20 est fixée sur le châssis inférieur 7 par des montants 38.The plate 20 is fixed on the lower frame 7 by uprights 38.

La platine 20, montée sur le châssis inférieur 7, peut donc évoluer entre une position basse de repos et une position haute de pincement des portions de feuille à évacuer.The plate 20, mounted on the lower frame 7, can therefore move between a low rest position and a high pinch position portions of the sheet to be evacuated.

On comprendra qu'on peut prévoir plusieurs types de platine comportant autant de contre-tiges qu'on souhaite, surtout si on veut qu'elles soient proches les unes des autres, pour une facilité d'emploi en fonction des feuilles à décortiquer. Une platine à une seule tige est même envisageable.It will be understood that one can provide several types of platinum having as many counter-rods as desired, especially if they want them to be close to each other, for ease of use depending on the leaves to be peeled. A platinum with a single rod is even conceivable.

On a envisagé des platines comportant des plaques servant de paliers aux contre-tiges. On pourrait envisager des moyens autres que des plaques, comme par exemple des équerres ou autres profilés.Plates with plates for bearing against the rods have been envisaged. Means other than plates, such as brackets or other profiles, could be envisaged.

Le démontage et le repérage des platines sur leur châssis est facile et rapide.Disassembly and location of turntables on their chassis is easy and fast.

Les platines de l'invention offrent de plus l'avantage de pouvoir être stockées facilement, sans avoir à les démonter ou en les démontant pour gagner des espaces de stockage.The plates of the invention also offer the advantage of being easily stored, without having to disassemble or dismantling to gain storage space.

Grâce aux platines de l'invention, l'essentiel du module de décortication 2 peut être réalisé par CAO (conception assistée par ordinateur).Thanks to the plates of the invention, most of the decortication module 2 can be achieved by CAD (computer-aided design).
