Abstract
Description
La présente invention concerne un outil télescopique, pour une station d'éjection de déchets dans une machine travaillant des feuilles, comprenant un corps cylindrique creux dans lequel s'engage la partie arrière d'une aiguille présentant une collerette dont l'une des faces s'appuie contre la partie inférieure d'un premier alésage du corps cylindrique creux et dont l'autre face est en contact avec l'une des extrémités d'un ressort de compression logé dans ledit premier alésage fermé à son extrémité supérieure par un bouchon servant d'organe de fixation de l'outil et de pièce d'appui pour l'autre extrémité du ressort de compression, l'aiguille étant guidée avec du jeu dans ledit bouchon et dans la partie inférieure du corps cylindrique creux duquel dépasse la partie avant de ladite aiguille.The present invention relates to a telescopic tool, for a waste ejection station in a sheet-working machine, comprising a hollow cylindrical body in which engages the rear part of a needle having a flange, one of the faces of which bears against the lower part of a first bore of the hollow cylindrical body and the other face of which is in contact with one of the ends of a compression spring housed in said first bore closed at its upper end by a plug serving tool fixing member and support piece for the other end of the compression spring, the needle being guided with play in said plug and in the lower part of the hollow cylindrical body from which the front part protrudes of said needle.
De tels outils, bien connus des utilisateurs, sont déjà utilisés couramment dans la station d'éjection des déchets des machines travaillant des feuilles, par exemple des presses de découpage de feuilles de carton.Such tools, well known to users, are already commonly used in the waste ejection station of sheet processing machines, for example presses for cutting cardboard sheets.
Ces outils sont montés, dans la station d'éjection des déchets de la presse de découpage, de façon à pouvoir être réglés en fonction de la position des déchets à éjecter, sur des cadres supérieur et inférieur composés de traverses déplaçables. Une telle utilisation est représentée dans la description du brevet DE-A-2158907 qui correspond au préambule de la revendication 1.These tools are mounted, in the waste ejection station of the cutting press, so that they can be adjusted as a function of the position of the waste to be ejected, on upper and lower frames composed of movable crosspieces. Such use is shown in the description of patent DE-A-2158907 which corresponds to the preamble of
Le brevet GB-A-1334014 se rapporte à un outil d'éjection de déchets comportant un dispositif amortisseur de bruit se présentant sous la forme d'un coussin élastique constitué par une rondelle circulaire.Patent GB-A-1334014 relates to a waste ejection tool comprising a noise damping device in the form of an elastic cushion constituted by a circular washer.
En règle générale, ces cadres sont animés d'un mouvement vertical alternatif destiné à appliquer les extrémités des aiguilles supérieures et inférieures sur la surface du déchet, de façon à, dans un premier temps, le pincer puis, dans une deuxième opération, à l'accompagner vers le bas dans un plan différent du plan de la feuille et ensuite, à le lâcher en éloignant à nouveau les cadres et, par là, les aiguilles, de façon à ce que le déchet puisse être éliminé de la feuille. Pendant cette opération, l'aiguille se déplace donc suivant un mouvement de va-et-vient dans son corps cylindrique creux. Il est bien entendu que, pendant l'opération d'éjection des déchets, la feuille, prise entre les organes de transfert de la presse, aura été maintenue dans une position d'arrêt et que, l'éjection ayant eu lieu, la feuille sans déchets sera enlevée de la station d'éjection à l'aide des organes de transport qui amèneront alors dans la station une nouvelle feuille à traiter.As a rule, these frames are moved in an alternating vertical movement intended to apply the ends of the upper and lower needles to the surface of the waste, so as to first pinch it then, in a second operation, to accompany it downwards in a plane different from the plane of the sheet and then to release it by moving the frames away again and, through there, the needles, so that the waste can be removed from the sheet. During this operation, the needle therefore moves back and forth in its hollow cylindrical body. It is understood that, during the waste ejection operation, the sheet, taken between the transfer members of the press, will have been kept in a stopped position and that, having ejected, the sheet without waste will be removed from the ejection station using the transport devices which will then bring into the station a new sheet to be treated.
Il faut souligner, qu'en règle générale, les feuilles comportent un grand nombre de déchets à éjecter et que, par conséquent, les cadres supérieur et inférieur seront équipés d'un grand nombre d'outils télescopiques. Il est évident que la masse représentée par les cadres et les outils sera importante et que, dans le cas de presses rapides que l'on utilise dans ce domaine, les forces d'inertie mises en jeu seront importantes, et que la commande de la presse devra être dimensionnée en conséquence.It should be noted that, as a rule, the sheets contain a large number of waste to be ejected and that, consequently, the upper and lower frames will be equipped with a large number of telescopic tools. It is obvious that the mass represented by the frames and the tools will be significant and that, in the case of rapid presses which are used in this field, the inertial forces brought into play will be significant, and that the control of the press should be sized accordingly.
Jusqu'à maintenant, les corps cylindriques creux des outils étaient réalisés en aluminium ou en un alliage d'aliminium, et les aiguilles elles-mêmes étaient en acier.Until now, the hollow cylindrical bodies of the tools have been made of aluminum or an aluminum alloy, and the needles themselves have been made of steel.
L'utilisation de tels outils télescopiques montés dans leur cadres inférieur et supérieur présente de nombreux inconvénients lorsque l'on désire encore augmenter la vitesse de production de la presse. Le premier de ces inconvénients réside dans le bruit important résultant de l'arrivée en contact des aiguilles en acier avec le déchet à traiter. Le deuxième inconvénient est relatif à l'usure, par matage, des pointes des aiguilles, ce qui, dans certains cas d'usure avancée, provoque, de par la décomposition de la force d'appui des pointes des aiguilles sur le déchet, un coincement de l'aiguille dans les alésages du corps cylindrique creux et du bouchon de fermeture de celui-ci. On a, en effet, remarqué, en cours de production, que la pointe des aiguilles se déformait de telle façon qu'elle pouvait présenter un plan incliné. On a même observé, dans certains cas, une rupture totale de l'aiguille due aux efforts importants qu'elle subissait à la suite de l'usure de son extrémité.The use of such telescopic tools mounted in their lower and upper frames has many disadvantages when it is desired to further increase the speed of production of the press. The first of these drawbacks lies in the significant noise resulting from the arrival in contact of the steel needles with the waste to be treated. The second disadvantage relates to the wear, by matting, of the points of the needles, which, in certain cases of advanced wear, causes, by the decomposition of the force of support of the points of the needles on the waste, jamming of the needle in the bores of the hollow cylindrical body and of the closure cap thereof. It has, in fact, been noticed, during production, that the point of the needles deformed in such a way that it could have an inclined plane. It has even been observed, in certain cases, a total rupture of the needle due to the significant forces which it underwent following the wear of its end.
L'usure en biais de la pointe des aiguilles peut provenir soit d'un mauvais alignement entre l'aiguille supérieure et l'aiguille inférieure, soit d'un montage défectueux, par exemple en biais, des outils télescopiques.The skew wear of the point of the needles can come either from a bad alignment between the upper needle and the lower needle, or from a defective assembly, for example in bias, telescopic tools.
Un troisième inconvénient est représenté par la masse relativement importante de chacun des outils télescopiques qui oblige le constructeur de la presse à découper à utiliser des organes de commande fortement dimensionnés ce qui, par l'évidence, a une influence défavorable sur l'augmentation de vitesse de production recherchée.A third drawback is represented by the relatively large mass of each of the telescopic tools which obliges the manufacturer of the cutting press to use highly dimensioned control members which, obviously, has an unfavorable influence on the increase in speed. of production sought.
L'invention a pour but d'apporter une solution aux problèmes existants, sans compliquer les principes actuels de construction et sans augmenter, dans une mesure insoutenable, le prix d'un outil télescopique. Elle présente, en particulier, l'avantage d'assurer un contact parfait de l'extrémité de l'aiguille avec le déchet à éjecter tout en évitant les risques de coincement de celle-ci, ceci sans tenir compte de l'angle d'action de celle-ci contre le déchet. De plus, la qualité élastique de l'extrémité de l'aiguille réduit, dans une mesure appréciable, l'usure des faces de contact de l'outil avec le déchet, ce qui influe, de façon non négligeable, sur la durée de vie de celui-ci tout en assurant un meilleur pincement du déchet à éjecter.The invention aims to provide a solution to existing problems, without complicating current construction principles and without increasing, to an unsustainable extent, the price of a telescopic tool. It has, in particular, the advantage of ensuring perfect contact of the end of the needle with the waste to be ejected while avoiding the risk of jamming thereof, this without taking into account the angle of action thereof against the waste. In addition, the elastic quality of the end of the needle reduces, to an appreciable extent, the wear of the contact faces of the tool with the waste, which has a non-negligible influence on the service life. of it while ensuring better pinching of the waste to be ejected.
A cet effet, l'invention est définie en conformité avec ce qu'énonce la revendication 1.To this end, the invention is defined in accordance with what is stated in
Le dessin annexé, comprenant une figure unique représente, à titre d'exemple, une forme d'exécution d'un outil télescopique selon l'invention.The appended drawing, comprising a single figure represents, by way of example, an embodiment of a telescopic tool according to the invention.
Cette figure est une coupe longitudinale schématique au travers d'un outil télescopique 1 qui comprend un corps cylindrique creux 2, de préférence en matière synthétique, dans lequel est usiné un premier alésage 3 dans le prolongement duquel est usiné un second alésage 4 ayant un diamètre plus petit. Le premier alésage comporte, à son extrémité supérieure, un taraudage 5 dans lequel est vissé un bouchon 6. Le bouchon 6 est agencé de façon à présenter un filetage 7 destiné à la fixation de l'outil télescopique dans les supports d'un cadre d'éjection (non représenté). Ce bouchon 6 présente également un alésage de guidage 8 pour la partie arrière 9a de l'aiguille 10. Deux perçages 11 et 12 débouchent au sommet de l'alésage de guidage 8. Ces perçages 11 et 12 ont, d'une part, la fonction de canalisation d'échappement de l'air et des poussières pénétrant dans l'outil télescopique lors de son fonctionnement et, d'autre part, ils servent de moyens de serrage pour le montage de l'outil sur son support, cela en introduisant une tige dans les deux perçages 11 et 12 pour bloquer le filetage 7 dans le support. L'aiguille 10 possède une partie arrière 9a et une partie avant 9b, séparées par une collerette 13. La partie avant 9b de l'aiguille 10 est composée d'un élément rigide 14 et d'un élément déformable 15. La partie arrière 9a de l'aiguille 10 est équipée d'un ressort de compression 16 qui s'appuie, d'une part, sur la face 17 de la collerette 13 et, d'autre part, contre la face 18 du bouchon 6. La partie avant 9b de l'aiguille 10 est guidée dans le second alésage 4 et elle est munie d'un organe amortisseur de bruit 19 placé entre la face 20 de la collerette 13 et la partie inférieure 21 du premier alésage 3. Les parties arrière 9a et avant 9b de l'aiguille 10 coulissent librement dans les deux alésages 4 et 8. L'élément rigide 14 de la partie avant 9b de l'aiguille 10 est avantageusement réalisé par une tige d'aluminium dont la surface a été durcie par un eloxage ou un traitement par anodisation. Il est à remarquer que toute l'aiguille peut être traitée, de façon à présenter une surface durcie. L'élément élastique 15 peut, quant à lui, être un élastomère tel que du polyuréthane et être fixé à l'élément rigide par vulcanisation ou éventuellement par collage ou tout autre moyen de fixation permanente. Il va de soi que tout autre élastomère, comme du caoutchouc naturel ou synthétique, des polyacrylates, du néoprène, etc, pourrait être utilisé pour fabriquer l'élément élastique 15. On pourrait également imaginer que l'élastomère soit remplacé par tout autre élément présentant des caractéristiques semblables d'élasticité. L'organe amortisseur de bruit 19 est réalisé, dans cette exécution, à partir d'un anneau en élastomère pouvant, par exemple, avoir les mêmes caractéristiques que les matériaux utilisés pour fabriquer l'élément déformable 15.This figure is a schematic longitudinal section through a
L'utilisation d'un outil tel que celui qui vient d'être décrit ci-dessus permet donc de réduire les forces d'inerties engendrées par sa masse, de diminuer le niveau sonore de la station d'éjection, d'autoriser une erreur de positionnement angulaire de l'outil par rapport au plan du déchet à éjecter, et de supprimer les risques de coincement ou de grippage de l'aiguille dans les alésages de guidage du corps cylindrique creux de l'outil télescopique.The use of a tool such as that which has just been described above therefore makes it possible to reduce the inertial forces generated by its mass, to reduce the noise level of the ejection station, to allow an error angular positioning of the tool relative to the plane of the waste to be ejected, and to eliminate the risk of jamming or jamming of the needle in the guide bores of the hollow cylindrical body of the telescopic tool.
