Abstract
Description
La présente invention concerne un outil supérieur mobile universel pour une station d'éjection de déchets dans une machine de découpage d'éléments en forme de bande ou de feuille en vue de la production d'emballages, selon le préambule de la revendication 1.The present invention relates to a universal mobile upper tool for a waste ejection station in a machine for cutting strip or sheet-shaped elements for the production of packaging, according to the preamble of claim 1.
Lors de la production d'emballages, des feuilles sont introduites une à une dans une presse de découpage. Après découpage, chaque feuille se présente sous la forme de plusieurs découpes ou poses juxtaposées et réunies encore entre elles par des points d'attache (qui seront éliminés par la suite), chaque pose correspondant à une boîte d'emballage. Toutefois, les poses n'occupent pas toute la superficie de la feuille; en effet, certaines parties, situées entre deux poses ou à la périphérie de la feuille, forment des déchets qu'il faut ôter de cette dernière. C'est pour cela que, sitôt après la station de découpage, chaque feuille est introduite individuellement dans une station d'éjection de déchets. Cette station comprend un outil supérieur mobile muni de poussoirs et un outil inférieur sous forme de planche ajourée. Pour l'éjection des déchets, la feuille ayant été placée sur l'outil inférieur, l'outil supérieur est ensuite déplacé vers le bas de manière à ce que ses poussoirs forcent les déchets à passer au travers d'ouvertures correspondantes de la planche ajourée.During the production of packaging, sheets are introduced one by one into a cutting press. After cutting, each sheet is in the form of several cuts or poses juxtaposed and joined together by attachment points (which will be eliminated later), each pose corresponding to a packaging box. However, the poses do not occupy the entire surface of the sheet; in fact, certain parts, located between two exposures or at the periphery of the sheet, form waste which must be removed from the latter. This is why, as soon as after the cutting station, each sheet is introduced individually into a waste ejection station. This station includes a mobile upper tool provided with pushers and a lower tool in the form of a perforated board. For the ejection of the waste, the sheet having been placed on the lower tool, the upper tool is then moved down so that its pushers force the waste to pass through corresponding openings in the perforated board .
Pour maintenir, durant l'éjection des déchets, la feuille en place et plaquée contre la planche ajourée, il est connu de placer sur l'outil supérieur des presseurs en caoutchouc mousse ou similaire.To keep the sheet in place and pressed against the perforated board during ejection of the waste, it is known to place foam rubber pressers or the like on the upper tool.
Il est connu de réaliser des outils dit universels, c'est-à-dire qui s'adaptent à différentes répartitions et configurations des déchets d'une feuille. Un tel outil supérieur universel, décrit par exemple dans la demande de brevet publiée DE-A-1149976, est constitué d'un support comportant une pluralité de barres entrecroisées sur lesquelles sont montés des poussoirs et des presseurs élastiques. Par un déplacement adéquat des poussoirs et des presseurs élastiques le long des différentes barres entrecroisées, il est possible d'adapter l'outil supérieur à chaque nouveau travail.It is known to produce so-called universal tools, that is to say which adapt to different distributions and configurations of the waste of a sheet. Such a universal upper tool, described for example in published patent application DE-A-1149976, consists of a support comprising a plurality of intersecting bars on which are mounted pushers and elastic pressers. By appropriately moving the pushers and elastic pressers along the various crisscross bars, it is possible to adapt the upper tool to each new job.
Jusqu'à ce jour, la fixation des poussoirs et des presseurs élastiques sur l'outil supérieur a été réalisée par liaison mécanique.
Dans la pratique, on connaît aussi un outil dans lequel le support est constitué par une plaque horizontale de format au moins égal à celui de léa feuille et quadrillée d'un grand nombre d'ouvertures allongées au travers de chacune desquelles peut passer un élément de liaison entre un poussoir plaqué contre la face inférieure de la plaque, et des moyens de fixation rapide montés sur la face supérieure de cette même plaque. Par un choix judicieux des ouvertures allongées, et aussi un déplacement des poussoirs le long de ces dernières, il est possible, à l'aide d'une seule plaque et d'une série de poussoirs, d'adapter l'outil supérieur à chaque nouveau travail. Un tel outil est décrit dans le brevet CH-A-474340 (& DE-A-1923504). Ce document ne fait pas référence à des presseurs élastiques mais il était connu de la pratique que les presseurs élastiques décrits dans la demande de brevet publiée DE-A-1149976 pouvaient être remplacés par des presseurs, de préférence en caoutchouc mousse, fixés par collage contre la face inférieure de la plaque (voir préambule de la revendication 1). Le collage présente toutefois les inconvénients suivants :
- destruction des presseurs lors du décollage;
- impossibilité de réaliser un réajustage de position, une fois le presseur mis en place;
- nécessité de nettoyer la plaque.
In practice, a tool is also known in which the support is constituted by a horizontal plate of format at least equal to that of the leaf and squared with a large number of elongated openings through each of which can pass an element of connection between a pusher pressed against the underside of the plate, and quick fixing means mounted on the upper face of this same plate. By a judicious choice of elongated openings, and also a displacement of the pushers along these, it is possible, using a single plate and a series of pushers, to adapt the upper tool to each new job. Such a tool is described in patent CH-A-474340 (& DE-A-1923504). This document does not refer to elastic pressers but it was known in practice that the elastic pressers described in published patent application DE-A-1149976 could be replaced by pressers, preferably made of foam rubber, fixed by gluing against the underside of the plate (see preamble to claim 1). Bonding has the following disadvantages:
- destruction of the pressers during takeoff;
- inability to perform a position readjustment once the presser is in place;
- need to clean the plate.
Il a aussi été proposé de remplacer le collage par un adhésif à double-face qui présente aussi à peu près les mêmes inconvénients que le collage.It has also been proposed to replace the bonding with a double-sided adhesive which also has roughly the same disadvantages as bonding.
En conséquence, la présente invention a pour but de réaliser un outil supérieur qui élimine les inconvénients mentionnés ci-dessus.Consequently, the object of the present invention is to provide a superior tool which eliminates the drawbacks mentioned above.
Ce but est atteint grâce à un dispositif selon la revendication 1 ou 5.This object is achieved by a device according to claim 1 or 5.
D'autres caractéristiques et avantages de l'invention ressortiront de l'exemple de réalisation décrit ci-après en vue d'en faciliter la compréhension et en référence au dessin annexé dans lequel :
- la figure 1 est une vue de côté en coupe d'un outil supérieur selon l'invention;
- la figure 2 est une vue de côté (en coupe partielle selon B - B de la figure 3) d'un autre mode de réalisation de l'outil supérieur; et
- la figure 3 est une vue de dessus selon A de la figure 2.
- Figure 1 is a side sectional view of an upper tool according to the invention;
- Figure 2 is a side view (in partial section along B - B of Figure 3) of another embodiment of the upper tool; and
- FIG. 3 is a top view along A of FIG. 2.
L'outil supérieur, représenté à la figure 1, est constitué d'une plaque horizontale rectangulaire 1 quadrillée de trous allongés 10 répartis sur à peu près toute sa superficie. Des poussoirs P₁ (dont seulement deux sont représentés dans la figure 1) sont fixés, de façon amovible et contre la face inférieure de la plaque 1, à l'aide de moyens à fixation rapide S₁ situés sur la face supérieure de la plaque 1 et passant au travers des ouvertures 10. Les poussoirs P₁ peuvent être constitués soit d'un seul bloc rectangulaire 3 pouvant pivoter, selon un axe vertical, par rapport à la fixation S₁, soit d'un bloc 3 et d'une aiguille 2 fixée au bloc 3 (pour plus de détails voir la demande de brevet DE-A-1149976 mentionnée plus haut). Le nombre et l'emplacement des blocs 3 et des aiguilles 2 sont choisis pour qu'ils soient susceptibles de pousser les déchets au travers de l'outil inférieur.The upper tool, represented in FIG. 1, consists of a rectangular horizontal plate 1 squared with
Sur toute la surface inférieure de la plaque 1 sont réparties et collées des bandes adhérentes 7 que l'on trouve dans le commerce sous la marque VELCRO(R) et que l'on désignera par la suite, dans la présente demande de brevet, par le terme bande VELCRO(R). Des presseurs en caoutchouc mousse E₁, de forme rectangulaire, sont fixés à l'aide de bandes VELCRO 8 collées sur leur face supérieure, à l'encontre des bandes VELCRO(R) 7 et à l'endroit souhaité de la face inférieure de la plaque 1. Pour faciliter la mise en prise respective des bandes VELCRO(R) 7, 8, il s'est avéré qu'il était préférable que les presseurs E₁ soient munis de bandes 8 relativement étroites situées sur deux bords opposés de leur surface supérieure d'appui. Dans le cas des poussoirs P₁ et de leur moyens de fixation S₁ représentés dans la figure 1, il est préférable que les zones de la surface inférieure de la plaque 1, situées immédiatement à proximité des ouvertures 10, ne soient pas recouvertes des bandes VELCRO(R) 7 pour que les blocs rectangulaires 3 puisse prendre appui directement contre la plaque 1.Over the entire lower surface of the plate 1 are distributed and bonded adhesive strips 7 which are commercially available under the brand VELCRO (R) and which will be designated subsequently, in the present patent application, by the term VELCRO (R) tape. E₁ foam rubber pressers, shaped rectangular, are fixed with VELCRO 8 strips glued on their upper side, against VELCRO (R) 7 strips and at the desired location on the lower side of the plate 1. To facilitate engagement respective bands VELCRO (R) 7, 8, it turned out that it was preferable that the pressers E₁ be provided with
Dans la figure 2, l'outil supérieur universel est constitué d'une plaque 1' munie d'un grand nombre de trous 10' dans chacun desquels peut être introduite, par le haut, une aiguille 2' d'éjection. Chaque aiguille 2' est munie, à son extrémité supérieure, d'une tête 9 venant buter contre la face supérieure de la plaque 1'. Une planche 4 (non représentée dans la figure 3) placée, pendant l'éjection, sur les têtes 9, empêche les aiguilles 2' de s'échapper hors de la plaque 1'. La plaque 1' peut aussi être munie de poussoirs similaires (non représentés) à ceux en forme de bloc 3 de la figure 1. Toute la surface inférieure de la plaque 1' peut être, par exemple, recouverte d'une couche VELCRO(R) 7', déposée antérieurement à la réalisation des trous 10' pour qu'elle soit perforée simultanément avec ces derniers.In FIG. 2, the universal upper tool consists of a plate 1 'provided with a large number of holes 10' into each of which can be inserted, from above, a needle 2 'for ejection. Each needle 2 'is provided, at its upper end, with a
Dans le cas de la figure 2, un gain considérable de place pour le stockage est obtenu du fait que toutes les aiguilles 2' et presseurs E'₁ peuvent être ôtés de la plaque.In the case of FIG. 2, a considerable saving of space for storage is obtained due to the fact that all the needles 2 'and pressers E'₁ can be removed from the plate.
L'utilisation de bandes VELCRO(R), telle que décrite ci-dessus, dans la mise en place des presseurs permet donc :
- un montage rapide, aisé et peu coûteux des presseurs;
- un démontage rapide et non destructif des presseurs, c'est-à-dire leur récupération pour des travaux suivants;
- un réajustage aisé d'un presseur déjà mis en place.
- quick, easy and inexpensive assembly of the pressers;
- rapid and non-destructive disassembly of the pressers, that is to say their recovery for subsequent work;
- easy readjustment of a presser already in place.
Des modifications peuvent être apportées sans sortir du cadre de l'invention. Par exemple, les bandes VELCRO(R) peuvent être remplacées par un système de fixation basé sur le principe des plots de jeu de la marque LEGO(R) et qui est suffisamment connu pour ne pas devoir être décrit ici plus en détails.Modifications can be made without departing from the scope of the invention. For example, the VELCRO (R) bands can be replaced by a fixing system based on the principle of LEGO (R) brand play pads and which is sufficiently well known that it should not be described here in more detail.
