Description
L'invention concerne un organe de retenue de feuilles pour un magasin d'empilage, notamment pour un magasin d'empilage de flancs découpés, de plaques ou de boîtes de carton, du type comprenant une grille supérieure et une grille inférieure de retenue des feuilles, constituées par les tiges de vérins disposés dans les parois frontale et arrière du magasin.The invention relates to a sheet retaining member for a stacking magazine, in particular for a magazine for stacking cut sides, plates or cardboard boxes, of the type comprising an upper grid and a lower sheet retaining grid. , constituted by the rods of cylinders arranged in the front and rear walls of the magazine.
Dans la pratique, on connaît déjà des magasins d'empilage de feuilles de carton ondulé travaillant conjointement avec des courroies transporteuses amenant les feuilles au-dessus du magasin d'empilage. Ces courroies transporteuses sont en général agencées de façon à ce qu'elles puissent lâcher les feuilles au dessus du magasin d'empilage dans lequel elles tombent par gravité.In practice, already known stores for stacking sheets of corrugated cardboard working in conjunction with conveyor belts bringing the sheets above the stacking store. These conveyor belts are generally arranged so that they can drop the sheets above the stacking magazine into which they fall by gravity.
Un tel magasin d'empilage est décrit plus en détail dans la demande de brevet EP-A-501 213, document appartenant à l'état de la technique selon l'Art. 54(3) CBE. Ce magasin d'empilage comprend entre autres une paroi frontale et une paroi arrière dans lesquelles sont montés des vérins dont les tiges, lorsqu'elles sont avancées, constituent une première grille de retenue des feuilles permettant l'évacuation d'un paquet de feuilles préalablement formé sur une seconde grille de retenue également constituée par les tiges d'autres vérins montés eux-aussi dans les parois frontale et arrière. L'évacuation du paquet formé sur la seconde grille étant assurée, après que les tiges des vérins de la seconde grille aient été escamotées, par un transporteur à rouleaux.Such a stacking magazine is described in more detail in patent application EP-A-501,213, a document belonging to the state of the art according to Art. 54 (3) EPC. This stacking store includes, among other things, a front wall and a rear wall in which jacks are mounted, the rods of which, when they are advanced, constitute a first sheet retaining grid allowing the evacuation of a packet of sheets beforehand. formed on a second retaining grid also constituted by the rods of other jacks also mounted in the front and rear walls. The evacuation of the package formed on the second grid being ensured, after the rods of the cylinders of the second grid have been retracted, by a roller conveyor.
Les vérins utilisés dans le dispositif mentionné ci-avant sont des vérins conventionnels que l'on peut trouver dans le commerce. En particulier, leurs tiges sont métalliques et de ce fait très rigides.The jacks used in the device mentioned above are conventional jacks that can be found commercially. In particular, their rods are metallic and therefore very rigid.
A l'utilisation, on a remarqué que lors d'un bourrage, dans le cas d'un travail à grande vitesse, la rigidité des tiges métalliques des vérins constituait un inconvénient non négligeable en ce sens que l'accumulation des feuilles entre la première grille, en l'occurrence la grille supérieure, formée par les tiges des vérins, et les courroies transporteuses causait des dégâts importants aux tiges des vérins voire, dans certains cas, leur rupture. De plus la remise en fonction du dispositif après un bourrage s'avère très difficile en raison de la compression des feuilles entre la grille et les courroies transporteuses qui empêche un retrait aisé des tiges des vérins, celles-ci étant plus ou moins fléchies ou courbées et coincées dans les guidages de leurs vérins respectifs.In use, it has been observed that during tamping, in the case of high-speed work, the rigidity of the metal rods of the jacks constitutes a non-negligible drawback in that the accumulation of the sheets between the first grid, in this case the upper grid, formed by the rods of the cylinders, and the conveyor belts caused significant damage to the rods of the cylinders or, in certain cases, their rupture. In addition, the resetting of the device after jamming is very difficult due to the compression of the sheets between the grid and the conveyor belts which prevents easy removal of the rods from the jacks, the latter being more or less bent or curved. and stuck in the guides of their respective cylinders.
On a même observé, dans certains cas, des déformations permanentes tellement importantes des tiges des vérins qu'il devenait impossible de les escamoter à l'intérieur des vérins.It has even been observed, in certain cases, such significant permanent deformations of the rods of the jacks that it becomes impossible to retract them inside the jacks.
Des vérins utilisés dans des magazins d'empilage sont connus aussi par les documents DE-A-195 7337 et EP-A-153 983.Cylinders used in stacking stores are also known from documents DE-A-195 7337 and EP-A-153 983.
La présente invention a pour but de remédier aux inconvénients précités en résolvant le problème posé par la déformation permanente des tiges des vérins lors d'un bourrage intervenant dans un magasin d'empilage.The present invention aims to remedy the aforementioned drawbacks by solving the problem posed by the permanent deformation of the rods of the jacks during jamming occurring in a stacking magazine.
A cet effet, selon l'un des aspects de l'invention, l'organe de retenue des feuilles est constitué par une série de vérins comportant chacun une tige déformable élastiquement, de façon non permanente, enchâssée à l'une de ses extrémités dans un piston lui aussi déformable élastiquement de façon non permanente, la tige ainsi que le piston des vérins etant déformables elastiquement de façon que, lors d'un bourrage eventuel survenant pendant l'empilage des feuilles sur les tiges des vérins, ces tiges se déforment elastiquement et ne soient pas deteriorées par une déformation permanente et en ce que ladite tige déformable élastiquement de façon non permanente est guidée, lors de son déplacement, dans un palier et par la surface circonférentielle du piston coulissant dans la jupe du cylindre du vérin.To this end, according to one aspect of the invention, the sheet retaining member is constituted by a series of jacks each comprising an elastically deformable rod, in a non-permanent manner, embedded at one of its ends in a piston also elastically deformable in a non-permanent manner, the rod as well as the piston of the cylinders being elastically deformable so that, during a possible jamming occurring during the stacking of the sheets on the rods of the cylinders, these rods elastically deform and are not damaged by permanent deformation and in that said elastically non-permanently deformable rod is guided, during its movement, in a bearing and by the circumferential surface of the piston sliding in the skirt of the cylinder of the jack.
Selon un autre aspect de l'invention, la tige élastiquement déformable, de façon non permanente, de chacun des vérins est guidée, lors de son déplacement dans un palier lisse.According to another aspect of the invention, the elastically deformable rod, in a non-permanent manner, of each of the jacks is guided, during its movement in a smooth bearing.
Avantageusement, la tige élastiquement déformable, de façon non permanente, de chacun des vérins est guidée, lors de son déplacement dans un palier à rotule.Advantageously, the elastically deformable rod, in a non-permanent manner, of each of the jacks is guided, during its movement in a spherical bearing.
De préférence, la tige élastiquement déformable, de façon non permanente, de chacun des vérins est réalisée en polyester thermoplastique.Preferably, the elastically deformable rod, in a non-permanent manner, of each of the jacks is made of thermoplastic polyester.
De préférence enfin, le piston déformable élastiquement, de façon non permanente, est réalisé en polyester thermoplastique.Preferably finally, the elastically deformable piston, in a non-permanent manner, is made of thermoplastic polyester.
Les avantages obtenus grâce à cette invention consistent essentiellement en ce que lors d'un bourrage éventuel survenant pendant l'empilage des feuilles de carton ondulé sur les tiges des vérins, ces tiges ne soient pas détériorées et par là qu'aucun remplacement des vérins éventuellement détériorés ne soit nécessaire.The advantages obtained thanks to this invention essentially consist in that during a possible jamming occurring during the stacking of the sheets of corrugated cardboard on the rods of the jacks, these rods are not deteriorated and by this that no replacement of the jacks possibly deteriorated is necessary.
Par conséquent, l'utilisation d'un organe de retenue selon l'invention permet d'assurer un meilleur rendement du dispositif d'empilage en raison de la facilité et de la rapidité de remettre ce dispositif d'empilage en service après un bourrage intempestif.Consequently, the use of a retaining member according to the invention makes it possible to ensure a better performance of the stacking device due to the ease and speed of putting this stacking device back into service after an untimely tamping. .
Une forme de réalisation d'un organe de retenue de feuilles est décrite ci-après, à titre d'exemple, à l'aide des dessins annexés dans lesquels :
- La figure 1 représente un dispositif d'empilage,
- La figure 2 représente, en coupe partielle, une première forme de réalisation d'un vérin de l'organe de retenue et,
- La figure 3 représente, en coupe partielle, une seconde forme de réalisation d'un vérin de l'organe de retenue.
- FIG. 1 represents a stacking device,
- FIG. 2 represents, in partial section, a first embodiment of a cylinder of the retaining member and,
- Figure 3 shows, in partial section, a second embodiment of a cylinder of the retaining member.
Le dispositif d'empilage 1 représenté sur la figure 1 comprend une série de courroies transporteuses 2 coopérant avec un dispositif d'aspiration 3 et un organe d'éjection 4 des feuilles de carton ondulé. Les feuilles de carton ondulé, provenant d'une machine de traitement placée en amont du dispositif d'empilage 1, sont transportées par les courroies transporteuses 2 jusqu'au dessus d'un magasin 6, formé d'une paroi frontale 7 et d'une paroi arrière 8, dans lequel elles seront empilées après avoir été détachées des courroies transporteuses 2 au moyen de l'organe d'éjection 4. Dans un premier temps, les feuilles de carton ondulé s'empileront sur une grille inférieure 9 matérialisée par les tiges métalliques des vérins 10 et 11 agencés dans les parois frontale 7 et arrière 8. Sur la figure 1, les tiges des vérins 10 et 11 sont en position escamotée car la pile 12 de feuilles de carton ondulé déjà formée est représentée dans sa phase d'évacuation sur les rouleaux du transporteur 13. Comme on peut le remarquer sur la figure 1, une grille supérieure 14, formée par les tiges métalliques 15 et 16 des vérins 17 et 18, est disposée au voisinage inférieur des courroies transporteuses 2 de façon à retenir les feuilles de carton ondulé arrivant dans le dispositif d'empilage 1 durant le temps nécessaire aux opérations d'évacuation de la pile 12 de feuilles déjà formée.The
Le genre de dispositif d'empilage 1 que nous venons de décrire travaille à grande vitesse et il peut se produire quelquefois des bourrages intempestifs dûs, par exemple, à une feuille non conforme ou détériorée arrivant dans le dispositif.The kind of
Il se produit alors une accumulation de feuilles entre la feuille 19, ou un petit paquet de ces feuilles, reposant sur les tiges 15 et 16 et les courroies transporteuses 2. L'accumulation de feuilles est symboliquement représentée ici par une feuille détériorée 20.An accumulation of leaves then occurs between the
Le carton ondulé étant une matière relativement résistante, son accumulation entre les courroies transporteuses 2 et les tiges 15 et 16 de la grille supérieure 14 va engendrer des efforts importants sur les tiges 15 et 16 et même provoquer sur celles-ci une déformation permanente, voire leur détérioration complète ou leur rupture. Comme représenté sur la figure 1, les tiges métalliques 15 et 16 sont courbées sous l'effet du bourrage et on peut comprendre, à l'évidence, qu'il ne sera pas possible d'actionner les vérins 17 et 18 pour rétablir des conditions de fonctionnement normales en éliminant les feuilles comprimées entre les tiges 15 et 16 et les courroies transporteuses 2. Un démontage complet de cette partie du dispositif d'empilage 1 sera donc nécessaire et prendra beaucoup de temps pour rétablir la situation. Il faudra même, dans le cas où les tiges 15 et 16 ont subi une déformation permanente ou ont été irrémédiablement endommagées, procéder au remplacement des vérins concernés.Corrugated cardboard is a relatively resistant material, its accumulation between the
La figure 2 représente, en coupe partielle, une première forme de réalisation d'un vérin 17, respectivement 18, de la grille supérieure 14. Le vérin 17 comporte un cylindre 25 obturé à l'une de ses extrémités par un manchon 26 au travers duquel s'effectue l'alimentation en fluide de ce vérin. Dans le présent cas, le fluide utilisé est de l'air comprimé. L'autre extrémité du cylindre 25 est, quant à elle, fermée par un autre manchon 27 dans lequel est agencé un palier lisse 28 servant de guidage pour la tige 15, respectivement 16, du vérin 17. Le palier lisse 28, est de préférence constitué d'une douille 29 et d'un joint d'étanchéité 30.FIG. 2 represents, in partial section, a first embodiment of a
La tige 15 est une tige cylindrique et possède des caractéristiques mécaniques autorisant une déformation non permanente lorsque elle est soumise à des efforts radiaux illustrés théoriquement ici par la simple flèche 31. Ainsi que nous l'avons précédemment exposé, ces efforts sur les tiges 15, 16 formant la grille supérieure 14 proviennent essentiellement des forces engendrées par l'accumulation des feuilles de carton ondulé entre les courroies transporteuses 2 et les tiges 15, 16 de la grille 14 (voir figure 1). La tige 15 est de préférence réalisée en matière synthétique telle que du polyester thermoplastique mais on pourrait également imaginer de la réaliser par exemple au moyen d'un organe mécanique tel qu'un ressort à spires plates et jointives entouré d'une gaine assurant un déplacement acceptable de la tige dans le palier lisse 28.The
Dans l'exemple illustré sur la figure 2, la tige 15 est enchâssée dans un piston 32 où elle est assurée à l'aide d'une goupille 33. Dans cette exécution, le piston 32 est lui aussi réalisé en polyester thermoplastique de façon à ce qu'il puisse également être quelque peu déformé lorsque des efforts sont appliqués à la tige 15 quand elle occupe sa position avancée. Dans la forme de réalisation illustrée, le piston 32 est rappelé en arrière au moyen d'un ressort 34 prenant appui, d'une part, contre la face 35 du piston 32 et d'autre part contre la face 36 du manchon 27. On peut aisément imaginer, pour éviter l'utilisation de ce ressort 34, d'employer un vérin du type à double effet.In the example illustrated in Figure 2, the
La figure 3 représente, en coupe partielle, une seconde forme de réalisation d'un vérin 17, respectivement 18, de la grille supérieure 14. Dans cette forme de réalisation, le palier de guidage de la tige 15 logé dans le manchon 27 est un palier à rotule 37 ce qui assure un meilleur fonctionnement du vérin lors d'une déformation importante de la tige 15.FIG. 3 represents, in partial section, a second embodiment of a
Il est à remarquer que l'on pourrait, dans un esprit d'unification des éléments constituant les grilles de retenues, équiper aussi la grille inférieure 9 avec le type de vérin décrit ci-avant.It should be noted that one could, in a spirit of unification of the elements constituting the retaining grids, also equip the
