Abstract

The drive mechanism, esp. for a sheet material cutting press, consists of a drive roller (11) and an associated rotary brush (12), forming an assembly located between the lower and upper sections of a margin table with a spring to apply a pressure against the upper surface of the sheet materials. The rotary brush is turned by the drive roller through a ring (53) set on a cylindrical head (51) connected to brush shaft (50). The ring is applied with a certain pressure against the inner surface of a circular chamber (47) inside the drive roller by the movement of a bearing (22). The roller and brush assembly is mounted on one end of a lever (21) pivoted to a bar on the upper section of the margin table.

Description

La présente invention a pour objet un dispositif auxiliaire d'entraînement pour le transport de feuilles de papier ou de carton, notamment pour le transport de feuilles de papier ou de carton, disposées sous forme de nappe, de la station de marge d'une presse à découper à la station de découpage d'une telle presse.The subject of the present invention is an auxiliary drive device for transporting sheets of paper or cardboard, in particular for transporting sheets of paper or cardboard, arranged in the form of a sheet, from the margin station of a press. to be cut at the cutting station of such a press.

Dans les presses à découper connues à ce jour, les feuilles à travailler sont prises du dessus d'une pile disposée dans la station de marge puis délivrées sous forme de nappe sur une table de marge avant d'être introduites dans les pinces des organes de transport de la station de découpage de la presse. Les feuilles sont bien entendu précisément positionnées longitudinalement et latéralement avant d'être saisies par les pinces des organes de transport de la station de découpage de la presse. Ce positionnement intervient à l'une des extrémités de la table de marge et s'effectue à l'aide de butées frontales et latérales contre lesquelles il conviendra d'appuyer la feuille devant être introduite dans la station de découpage de la presse. Les tables de marge que l'on connaît comprennent en général un plateau incliné servant de support pour les brins supérieurs de courroies de transport des feuilles, disposées côte à côte sur la largeur du plateau incliné. Pour assurer le transport des feuilles de la nappe sur la table de marge, il est prévu d'utiliser des éléments auxiliaires supérieurs de pression montés sur un cadre de façon à pouvoir être réglés en position au dessus du brin supérieur de chacune des courroies de transport des feuilles. Ces éléments auxiliaires de pression sont réalisés sous la forme de petits transporteurs à courroie dont la pression sur la nappe de feuilles à transporter peut être ajustée. Pour assurer l'appui, sans détérioration, du bord avant de la première feuille de la nappe contre les butées frontales, on utilise de préférence une brosse rotative dont l'axe de rotation est décalé longitudinalement par rapport à la poulie d'extrémité du transporteur à courroie. Ainsi, le bord arrière de la première feuille de la nappe ne sera pas poussé, dans le sens de son déplacement, par la courroie du transporteur mais uniquement par les poils de la brosse rotative qui céderont lorsque le bord avant de la première feuille de la nappe entrera en contact avec la butée frontale. De ce fait, la feuille ne sera pas déformée ou détériorée par une poussée trop violente des organes de transport. Dans ce genre de dispositif, il convient bien entendu d'entraîner la brosse rotative. Pour ce faire, on utilise le mouvement de l'une des poulies d'extrémité du transporteur supérieur que l'on transmet à la brosse à l'aide d'une courroie d'entraînement. Ces éléments auxiliaires de pression présentent cependant plusieurs inconvénients. Premièrement, leur construction n'autorise pas le réglage du couple de rotation de la brosse en raison de son entraînement par une courroie qui doit nécessairement être tendue pour être efficace. De plus ces éléments nécessitent l'utilisation d'un grand nombre de pièces, telles que des poulies, des courroies, au moins deux dispositifs de réglage de la pression, ce qui rend leur réalisation particulièrement coûteuse. Egalement, en raison de leur complication, leur réglage pour obtenir un transport acceptable de la nappe de feuilles est long et fastidieux.In the cutting presses known to date, the sheets to be worked are taken from the top of a stack placed in the margin station and then delivered in the form of a sheet on a margin table before being introduced into the clamps of the organs of transport from the press cutting station. The sheets are of course precisely positioned longitudinally and laterally before being gripped by the clamps of the transport members of the press cutting station. This positioning takes place at one end of the margin table and is carried out using front and side stops against which the sheet to be inserted in the press cutting station should be pressed. The margin tables that are known generally comprise an inclined plate serving as a support for the upper strands of leaf conveyor belts, arranged side by side over the width of the inclined plate. To ensure the transport of the sheets of the tablecloth on the margin table, provision is made to use upper auxiliary pressure elements mounted on a frame so that they can be adjusted in position above the upper strand of each of the conveyor belts. leaves. These auxiliary pressure elements are produced in the form of small belt conveyors whose pressure on the sheet of sheets to be transported can be adjusted. To ensure the support, without deterioration, of the front edge of the first sheet of the ply against the front stops, a rotary brush is preferably used, the axis of rotation of which is offset longitudinally relative to the end pulley of the conveyor belt. Thus, the rear edge of the first sheet of the web will not be pushed, in the direction of its movement, by the conveyor belt but only by the bristles of the rotary brush which will yield when the front edge of the first sheet of the tablecloth will come into contact with the front stop. Therefore, the sheet will not be deformed or deteriorated by a too violent push of the transport members. In this type of device, it is of course suitable to drive the rotary brush. To do this, use the movement of one of the end pulleys of the upper conveyor which is transmitted to the brush using a drive belt. These auxiliary pressure elements however have several drawbacks. Firstly, their construction does not allow adjustment of the torque of the brush due to its drive by a belt which must necessarily be tensioned to be effective. In addition, these elements require the use of a large number of parts, such as pulleys, belts, at least two pressure adjustment devices, which makes their production particularly expensive. Also, because of their complication, their adjustment to obtain an acceptable transport of the sheet of sheets is long and tedious.

Le but de la présente invention consiste à supprimer les inconvénients précités. A cet effet, l'invention a pour objet un dispositif conforme à ce qu'énonce la revendication 1.The object of the present invention is to eliminate the aforementioned drawbacks. To this end, the invention relates to a device in accordance with what is stated in claim 1.

L'invention sera mieux comprise à l'étude de l'une de ses formes d'exécution illustrée à l'aide des dessins annexés dans lesquels :

  • La figure 1 est une vue schématique destinée à l'explication du fonctionnement d'une table de marge,
  • La figure 2 est une vue en élévation d'un dispositif auxiliaire de pression pour le transport de feuilles de papier ou de carton et,
  • La figure 3 est une vue en coupe selon III-III de la figure 2.
The invention will be better understood from the study of one of its embodiments illustrated with the aid of the appended drawings in which:
  • FIG. 1 is a schematic view intended for the explanation of the operation of a margin table,
  • FIG. 2 is an elevation view of an auxiliary pressure device for transporting sheets of paper or cardboard and,
  • Figure 3 is a sectional view along III-III of Figure 2.

La figure 1 est une vue schématique destinée à l'explication du fonctionnement d'une table de marge 1. Cette table de marge 1 comprend une partie inférieure 2 et un partie supérieure 3. La partie inférieure 2 est constituée d'une série de courroies de transport inférieures 4 disposées côte à côte dans la largeur de la table de marge 1. Ces courroies 4 sont entraînées par un rouleau transversal 5 placé a l'avant de la table de marge 1 et elles passent autour d'un autre rouleau transversal de renvoi 6 placé à l'arrière de la table de marge 1. Le brin supérieur 7 des courroies de transport inférieures 4 est en appui sur une planche 8. Des feuilles 9, disposées en nappe sont amenées sur la partie inférieure 2 de la table de marge 1 par les organes d'introduction du margeur de la presse à découper, non représentés sur cette figure. La partie supérieure 3 de la table de marge comprend plusieurs dispositifs presseurs 10 composés chacun d'un galet d'entraînement 11 et d'une brosse rotative 12, la pression du galet d'entraînement 11 et de la brosse rotative 12 étant donnée par des ressorts 13. Chaque dispositif presseurs 10 est monté en regard de chacune des courroies de transport inférieures 4, sur un cadre (non représenté), de façon à presser sur la nappe de feuilles 9 et à en assurer l'entraînement. Dans l'exemple représenté par la figure 1, le bord avant de la première feuille 14 de la nappe est arrivée en contact avec la butée frontale 15 et dans cette position, son bord arrière est poussé par les poils de la brosse rotative 12 qui est reliée mécaniquement au galet d'entraînement 11. Celui-ci est, à ce moment là, toujours entraîné par l'effet du défilement de la nappe de feuilles 9 et transmet son mouvement de rotation à la brosse rotative 12. La première feuille 14 ayant été alignée contre la butée frontale 15, celle-ci sera escamotée et les pinces (non représentées) de l'organe de transport de la station de découpage de la presse pourront alors saisir cette première feuille 14 pour l'amener dans la station de découpage.Figure 1 is a schematic view for the explanation of the operation of a margin table 1. This margin table 1 comprises a lower part 2 and an upper part 3. The lower part 2 consists of a series of belts lower transport 4 arranged side by side in the width of the margin table 1. These belts 4 are driven by a transverse roller 5 placed at the front of the margin table 1 and they pass around another transverse roller of return 6 placed at the rear of the margin table 1. The upper strand 7 of the lower conveyor belts 4 is supported on a board 8. Sheets 9, arranged in a sheet are brought to the lower part 2 of the table margin 1 by the feeder introduction members of the cutting press, not shown in this figure. The upper part 3 of the margin table comprises several pressing devices 10 each composed of a drive roller 11 and a rotary brush 12, the pressure of the drive roller 11 and the rotary brush 12 being given by springs 13. Each pressing device 10 is mounted opposite each of the lower conveyor belts 4, on a frame (not shown), so as to press on the sheet of sheets 9 and to drive it. In the example shown in Figure 1, the front edge of the first sheet 14 of the web has come into contact with the front stop 15 and in this position, its rear edge is pushed by the bristles of the rotary brush 12 which is mechanically connected to the drive roller 11. This is, at this time, all days caused by the effect of the movement of the sheet ply 9 and transmits its rotational movement to the rotary brush 12. The first sheet 14 having been aligned against the front stop 15, the latter will be retracted and the clamps (not shown ) of the transport member of the press cutting station can then grasp this first sheet 14 to bring it into the cutting station.

La figure 2 est une vue en élévation d'un dispositif auxiliaire de pression 10 pour le transport d'une nappe de feuilles de papier ou de carton 9, 14. Ce dispositif comprend une pièce d'attache 16 réglable le long d'une barre 17 appartenant à la partie supérieure 3 de la table de marge 1. Cette partie supérieure 3 est composée de plusieurs barres 17 disposées côte à côte au dessus des brins supérieurs 7 des courroies de transport inférieures 4. La pièce d'attache 16 peut être bloquée en position le long de la barre 17 au moyen d'une plaquette 18 serrée par une poignée 19 vissée dans la pièce d'attache 16. La pièce d'attache 16 comporte aussi un pivot 20 pour supporter l'une des extrémités du levier 21 qui porte, à son autre extrémité, l'ensemble composé par le galet d'entraînement 11 et la brosse rotative 12. La brosse rotative est montée sur un palier 22 relié au levier 21 par un poulet moleté 23 traversant une ouverture allongée 24. L'extrémité du levier 21 située au voisinage du galet d'entraînement 11 et de la brosse rotative 12 comporte une protubérance 25 présentant deux fentes 26 et 27 dans lesquelles on peut engager l'extrémité 28 du ressort 13 constitué par une lame élastique ancrée à son autre extrémité 29 dans un plot 30 faisant partie de la pièce d'attache 16. Lorsque l'extrémité 28 du ressort 13 est engagée dans la fente 26, la force d'appui du galet d'entraînement 11 sera plus importante que lorsque cette extrémité 28 est engagée dans la fente 27. Pour affiner la force d'appui du galet d'entraînement 11 on utilise l'action d'une vis de réglage 31 avec écrou de bloquage 32. Cette vis de réglage 31 agit sur le ressort 13 et est vissée dans une patte 33 fixée au plot 30 par des vis 34 qui serrent en même temps l'extrémité 29 du ressort 13 dans le plot 30.Figure 2 is an elevational view of an auxiliary pressure device 10 for transporting a sheet of paper or cardboard sheets 9, 14. This device comprises a fastener 16 adjustable along a bar 17 belonging to the upper part 3 of the margin table 1. This upper part 3 is composed of several bars 17 arranged side by side above the upper strands 7 of the lower conveyor belts 4. The attachment piece 16 can be locked in position along the bar 17 by means of a plate 18 clamped by a handle 19 screwed into the attachment piece 16. The attachment piece 16 also includes a pivot 20 for supporting one of the ends of the lever 21 which carries, at its other end, the assembly composed of the drive roller 11 and the rotary brush 12. The rotary brush is mounted on a bearing 22 connected to the lever 21 by a knurled chicken 23 passing through an elongated opening 24. L end of the sink 21 located in the vicinity of the drive roller 11 and the rotary brush 12 has a protuberance 25 having two slots 26 and 27 in which one can engage the end 28 of the spring 13 constituted by an elastic blade anchored at its other end 29 in a stud 30 forming part of the attachment piece 16. When the end 28 of the spring 13 is engaged in the slot 26, the bearing force of the drive roller 11 will be greater than when this end 28 is engaged in the slot 27. To refine the bearing force of the drive roller 11, the action of an adjustment screw 31 with locking nut 32 is used. This adjustment screw 31 acts on the spring 13 and is screwed into a lug 33 fixed to the stud 30 by screws 34 which at the same time tighten the end 29 of the spring 13 in the stud 30.

La figure 3 est une vue en coupe selon III-III de la figure 2 à l'aide de laquelle la disposition des divers éléments composant le dispositif de pression 10 sera mieux comprise.Figure 3 is a sectional view along III-III of Figure 2 with which the arrangement of the various elements making up the pressure device 10 will be better understood.

Le levier 21 est composé d'une joue droite 35 et d'une joue gauche 36 écartées l'une de l'autre par des douilles 37 et 38. La douille 37 sert de palier pour le pivot 20 et la douille 38 est traversée par la vis de fixation 39 d'un bloc d'écartement 40 sur lequel est fixé le palier 22 au moyen du poulet moleté 23. La position du bloc d'écartement 40 est assurée par une goupille 41 qui traverse la joue droite 35. La joue gauche 36, de longueur un peu plus importante que la joue droite 35 supporte, à son extrémité 42, le galet d'entraînement 11. Le galet d'entraînement 11 est monté sur des roulements à billes 43 et 44 disposés sur l'axe 45 fixé à l'extrémité 42 de la joue gauche 36 par un écrou 46. Le galet d'entraînement 11 possède un chambrage 47 qui est concentrique par rapport à sa circonférence extérieure. Le palier 22 comporte deux roulements à billes 48 et 49 au travers desquels passe l'axe 50 de la brosse rotative 12. Cet axe 50 possède une tête cylindrique 51 présentant dans sa circonférence extérieure une rainure demi circulaire 52 dans laquelle est fixée une bague torique 53 réalisée en une matière ayant un coefficient de frottement correspondant par exemple à celui d'un caoutchouc synthétique du type néoprène ou similaire. La brosse rotative 12 est fixée à l'axe 50 à l'aide d'une goupille 54 et sa position latérale est déterminée par une rondelle de distance 55. L'axe 50 de la brosse rotative 12 est fixé aux roulements à billes 48 et 49 du palier 22 au moyen d'un écrou 56. Ainsi que l'on peut le voir à l'examen de cette figure, l'axe 45 du galet d'entraînement 11 et l'axe 50 de la brosse rotative 12 sont décalés l'un par rapport à l'autre de manière à ce que le point d'action du galet d'entraînement 11 soit situé en retrait du point d'action de la brosse rotative 12. L'entraînement de la brosse rotative 12 par le mouvement de rotation du galet d'entraînement 11 sera assuré par l'action de la bague torique 53 contre la paroi cylindrique du chambrage 47 aménagé dans le galet d'entraînement 11. Le couple d'entraînement de la brosse rotative 12 pourra être facilement ajusté en déplaçant plus ou moins le palier 22 dans la rainure allongée 24 et en le bloquant dans la position désirée au moyen du poulet moleté 23. Le démontage de la brosse rotative 12, par exemple pour procéder au remplacement après usure de la bague torique 53, sera également très facile puisqu'il suffira de dévisser complètement le poulet moleté 23 et de retirer le palier 22.The lever 21 is composed of a right cheek 35 and a left cheek 36 spaced from each other by sockets 37 and 38. The socket 37 serves as a bearing for the pivot 20 and the socket 38 is crossed by the fixing screw 39 of a spacer block 40 on which the bearing 22 is fixed by means of knurled chicken 23. The position of the spacer block 40 is ensured by a pin 41 which passes through the right cheek 35. The cheek left 36, slightly longer than the right cheek 35 supports, at its end 42, the drive roller 11. The drive roller 11 is mounted on ball bearings 43 and 44 arranged on the axis 45 fixed to the end 42 of the left cheek 36 by a nut 46. The drive roller 11 has a recess 47 which is concentric with respect to its outer circumference. The bearing 22 comprises two ball bearings 48 and 49 through which the axis 50 of the rotary brush 12 passes. This axis 50 has a cylindrical head 51 having in its outer circumference a semi-circular groove 52 in which is fixed an O-ring 53 made of a material having a coefficient of friction corresponding for example to that of a synthetic rubber of the neoprene type or the like. The rotary brush 12 is fixed to the axis 50 by means of a pin 54 and its lateral position is determined by a distance washer 55. The axis 50 of the rotary brush 12 is fixed to the ball bearings 48 and 49 of the bearing 22 by means of a nut 56. As can be seen on examining this figure, the axis 45 of the drive roller 11 and the axis 50 of the rotary brush 12 are offset relative to each other so that the point of action of the drive roller 11 is set back from the point of action of the rotary brush 12. The drive of the rotary brush 12 by the rotational movement of the drive roller 11 will be ensured by the action of the O-ring 53 against the cylindrical wall of the recess 47 arranged in the drive roller 11. The drive torque of the rotary brush 12 can be easily adjusted by moving the bearing 22 more or less in the elongated groove 24 and by blocking it in the off position sirée by means of the knurled chicken 23. The disassembly of the rotary brush 12, for example to proceed with the replacement after wear of the O-ring 53, will also be very easy since it will be enough to completely unscrew the knurled chicken 23 and remove the bearing 22.

Les avantages de la présente invention résident dans la simplicité de sa réalisation qui supprime l'utilisation des courroies d'entraînement, et dans la possibilité de nombreux réglages du couple d'entraînement de la brosse rotative 12.The advantages of the present invention lie in the simplicity of its construction which eliminates the use of drive belts, and in the possibility of numerous adjustments of the drive torque of the rotary brush 12.
