Description

La présente invention concerne une presse de façonnage de feuilles de papier ou de carton selon le préamble de la revendication 1.The present invention relates to a sheet-forming press of paper or cardboard according to the preamble of claim 1.

Les presses de façonnage de feuilles de papier, de carton compact ou de carton ondulé utilisent pour chaque tirage un ensemble d'outils de façonnage spécifique d'un travail donné. Un tel ensemble d'outils comprend typiquement :

  • une plaque de protection de feuille de mise,
  • une feuille de mise,
  • une forme à découper,
  • une tôle à découper portant les contreparties de découpe,
  • un outil supérieur d'éjection des déchets
  • une planche centrale d'éjection,
  • un cadre inférieur d'éjection portant des outils télescopiques de saisie de déchets,
  • un outil supérieur de séparation de poses,
  • un outil inférieur de séparation des poses.
The presses for shaping sheets of paper, compact cardboard or corrugated cardboard use for each print a set of tools for specific shaping of a given work. Such a set of tools typically includes:
  • a baking sheet protection plate,
  • a betting sheet,
  • a shape to cut,
  • a cutting sheet carrying the cutting counterparts,
  • a superior tool for waste ejection
  • a central ejection board,
  • a lower ejection frame carrying telescopic tools for seizing waste,
  • a superior tool for separating poses,
  • a lower tool for separating the poses.

L'outil supérieur d'éjection, tout comme l'outil supérieur de séparation de poses, peut se présenter sous forme d'un cadre-tiroir de dimensions standard, dont le côté avant et le côté arrière présentent des profils qui s'adaptent à et se glissent sur des dispositifs de fixation profilés, tels que des rails transversaux fixes et solidaires des stations correspondantes. Les termes "longitudinal" et "transversal" en ce qui concerne l'orientation d'une pièce, "avant", "arrière" et "latéral" en ce qui concerne un côté d'une station, sont employés ici en se référant à la direction d'avancement des feuilles dans la machine. Le cadre-tiroir peut recevoir plusieurs traverses, sur lesquelles sont fixés un ensemble d'éjecteurs. Les emplacements des traverses et des éjecteurs dans le cadre-tiroir sont modifiables et déterminés par le travail à effectuer. L'ajustage de leur position s'effectue hors machine, de préférence sur une table de réglage, et constitue la préparation de l'outil. Cette opération est relativement fastidieuse, mais s'effectue en "temps masqué", indépendamment de la machine en travail.The superior ejection tool, just like the superior separation tool poses, can be in the form of a standard-sized drawer frame, whose front and rear sides have profiles that adapt to and slide on profiled fasteners, such as cross rails fixed and solidarity of the corresponding stations. The terms "longitudinal" and "transversal" with respect to the orientation of a part, "before", "rear" and "lateral" with respect to one side of a station, are used here in referring to the direction of advancement of the sheets in the machine. The drawer frame can receive several sleepers, on which are fixed a set ejectors. The locations of sleepers and ejectors in the drawer frame are modifiable and determined by the work to be done. Adjusting their position is off-machine, preferably on a control table, and is the preparation of the tool. This operation is relatively tedious, but is done in "hidden time", regardless of the machine in work.

Pour des tirages courts et répétitifs, on utilise souvent un outil supérieur, appelé forme ou planche supérieure d'éjection, respectivement forme ou planche supérieure de séparation de poses, constitué d'une planche en bois rectangulaire, sur laquelle sont fixés à demeure des éjecteurs de formes variées, correspondant à ce travail spécifique. La forme en bois est elle-même montée à l'intérieur d'un cadre-tiroir. Ce cadre est ensuite placé dans la station correspondante. Cas échéant, la planche doit être réajustée en position et refixée dans le cadre.For short and repetitive prints, we often use a superior tool, called an upper form or an ejection board, respectively top layer of poses separation, consisting of a wooden board rectangular, on which ejector forms are fixed permanently varied, corresponding to this specific work. The wooden form is itself mounted inside a drawer frame. This frame is then placed in the station corresponding. If necessary, the board must be readjusted in position and reattached in the frame.

L'ensemble des outils mentionnés ci-dessus doit être disposé de manière extrêmement précise dans les différentes stations de la presse au début de chaque travail. En particulier dans le cas de tirages courts, la productivité de l'unité dépend dans une large mesure de la rapidité de la mise en place et du réglage des outils.All the tools mentioned above must be extremely precise way in the different stations of the press in beginning of each job. In particular in the case of short runs, the The productivity of the unit depends to a large extent on the speed of in place and adjusting the tools.

Le but de la présente invention est de faciliter et de rendre plus rapide la mise en place et l'ajustage de l'outil supérieur d'éjection et/ou de l'outil supérieur de séparation poses, notamment dans le cas de tirages courts et répétitifs.The purpose of the present invention is to facilitate and make faster the setting up and adjusting the upper ejector tool and / or the tool superior separation of poses, especially in the case of short runs and repetitive.

Ce but est atteint dans une presse de façonnage selon la revendication 1. This goal is achieved in a shaping press according to claim 1.

Une station d'éjection de déchets et/ou une station de séparation de poses, selon l'invention, permettent d'éliminer l'opération de montage et d'ajustage d'une planche supérieure d'éjection de déchets, respectivement d'une planche supérieure de séparation de poses dans un cadre-tiroir. Les planches sont montées directement dans la station. Il en résulte un gain de temps lors de la préparation de la presse entre deux travaux. Il en résulte également une économie au niveau du nombre de pièces d'outillage à utiliser. Le fait que le deuxième rail soit mobile permet d'ajuster l'écartement de la paire de rails à différentes dimensions de planches.A waste ejection station and / or a separation station poses, according to the invention, make it possible to eliminate the mounting operation and adjustment of an upper waste ejection board, respectively an upper board of separation of poses in a frame-drawer. The boards are mounted directly in the station. This results in a gain of time when preparing the press between two jobs. It results also a saving in the number of tooling parts to use. The fact that the second rail is movable makes it possible to adjust the spacing of the pair rails with different dimensions of boards.

Les rails de la station comportent une partie supérieure dont le profil est complémentaire du profil d'un cadre-tiroir et une partie inférieure dont le profil est complémentaire du profil d'une planche supérieure, les parties profilées des deux rails se faisant face.The rails of the station comprise an upper part whose profile is complementary to the profile of a drawer frame and a lower part of which the profile is complementary to the profile of a top board, the parts profiles of the two rails facing each other.

De préférence, le rail situé en avant de la station présente au niveau de la partie profilée recevant une planche supérieure, un plot de centrage destiné au centrage en machine de cette planche supérieure d'éjection ou de séparation. Pour pallier à d'eventuelles erreurs de fabrication de la planche, le plot de centrage est de préférence transversalement ajustable par un dispositif de réglage micrométrique.Preferably, the rail located in front of the station presents at the level of the profiled part receiving an upper board, a centering pad for at the machine centering of this upper ejection board or separation. To compensate for possible manufacturing errors of the board, the centering stud is preferably transversely adjustable by a device micrometric adjustment.

De préférence, la station comprend des moyens pour exercer une poussée sur le rail mobile, longitudinalement, en direction du rail fixe. De la sorte, lorsque l'outil supérieur est mis en place, il est maintenu serré sans jeu entre le rail fixe et le rail mobile.Preferably, the station comprises means for exercising a pushing on the movable rail, longitudinally, in the direction of the fixed rail. Of the so, when the upper tool is set up, it is held tight without play between the fixed rail and the movable rail.

Lesdits moyens poussant le rail mobile en direction du rail fixe peuvent comprendre au moins un ressort exerçant une poussée permanente sur le rail mobile en direction du rail fixe et au moins un vérin, dont la mise en action par l'opérateur contrecarre et surmonte l'action du ou des ressort(s), permettant le desserrage et le changement d'outils.Said means pushing the movable rail towards the fixed rail can include at least one spring exerting permanent thrust on the rail movable towards the fixed rail and at least one jack, the actuation by the operator counteracts and overcomes the action of the spring (s), allowing the loosening and changing tools.

Le rail mobile, qui est de préférence le rail arrière, peut être porté par au moins un support, lui-même ou eux-mêmes monté(s) sur un moyen de déplacement actionnable par l'opérateur. De la sorte, la station peut accueillir des planches supérieures de formats variables. En particulier, le rail mobile peut être porté par deux supports montés chacun sur une crémaillère à déplacement longitudinal.The movable rail, which is preferably the rear rail, can be worn by the least a support, himself or themselves mounted on a means of operator actionable movement. In this way, the station can accommodate top boards of varying sizes. In particular, the mobile rail can be carried by two supports each mounted on a rack to longitudinal displacement.

D'autres particularités et avantages de l'invention apparaítront pour l'homme du métier avec la description d'un mode d'exécution préféré, en référence au dessin, dans lequel :

  • la figure 1 est une vue en perspective d'une partie du châssis d'une station d'éjection de presse de façonnage avec une paire de rails permettant d'accueillir un outil supérieur d'éjection.
Other features and advantages of the invention will become apparent to those skilled in the art with the description of a preferred embodiment, with reference to the drawing, in which:
  • Figure 1 is a perspective view of a portion of the frame of a forming press ejection station with a pair of rails for accommodating an upper ejection tool.

La figure 1 montre un châssis porte-outil supérieur d'une station d'éjection de déchets d'une presse de façonnage avec deux poutres longitudinales 1 et 2 et deux poutres transversales 3 et 4. Un rail avant 5, transversal et horizontal, est suspendu aux poutres longitudinales 1 et 2 par deux montants (non visibles sur la figure). Le rail 5 présente sur son côté arrière deux rainures, une rainure inférieure 6 pouvant recevoir le bord d'une planche supérieure d'éjection et une rainure supérieure 7, dans laquelle peut venir se glisser une nervure d'un cadre-tiroir d'outil universel d'éjection. Le rail 5 reste normalement fixe par rapport au châssis porte-outil, aussi bien pendant le fonctionnement de la presse que pendant les changements d'outils. Toutefois, pour pallier de légères erreurs de fabrication ou de réglage d'un outil supérieur, des dispositifs d'ajustage micrométrique de position actionnables à la main sont prévus : le bouton moleté 8 permet d'ajuster la position transversale du plot de centrage destiné au centrage en machine d'une planche supérieure. Les boutons moletés 9 et 10 agissent, par l'intermédiaire d'une tringle 14 et de leviers, respectivement et indépendamment l'un de l'autre sur les deux montants auxquels est suspendu le rail 5, pour permettre de corriger la position longitudinale de celui-ci et/ou sa position angulaire. Ces trois dispositifs de réglage micrométrique sont pourvus d'un affichage, qui permet de stocker les valeurs de réglage en mémoire, pour les travaux répétitifs.Figure 1 shows a stationary upper tool frame of a station waste ejection of a forming press with two beams longitudinal 1 and 2 and two transverse beams 3 and 4. A front rail 5, transversal and horizontal, is suspended from the longitudinal beams 1 and 2 by two amounts (not visible in the figure). The rail 5 has on its side rear two grooves, a lower groove 6 can receive the edge of a upper ejection board and an upper groove 7, in which can come and slip a rib of a universal ejection tool drawer frame. The rail 5 remains normally fixed with respect to the tool carrier frame, both during the press operation only during tool changes. However, to mitigate slight manufacturing errors or adjustment of a superior tool, micrometric position adjustment devices operable by hand are provided: the knurled knob 8 makes it possible to adjust the transverse position of the centering pad for machine centering of an upper board. The knurled buttons 9 and 10 act, via a rod 14 and levers respectively and independently of each other on both to which the rail 5 is suspended, to enable the position to be corrected of the latter and / or its angular position. These three devices micrometric adjustment are provided with a display, which makes it possible to store setting values in memory, for repetitive jobs.

Face au rail 5 fixe, se trouve un rail postérieur 11 mobile, parallèle au rail fixe 5. Le rail 11 présente également une rainure inférieure pouvant accueillir le bord postérieur d'une planche supérieure d'éjection et une rainure supérieure dans laquelle peut venir se glisser une nervure complémentaire d'un cadre-tiroir d'outil supérieur d'éjection universel. Facing the fixed rail 5, there is a movable rear rail 11, parallel to the rail 5. The rail 11 also has a lower groove that can accommodate the posterior edge of an upper ejection board and a top groove in which can come to slip a complementary rib of a drawer-frame superior universal ejection tool.

Le rail postérieur mobile 11 est porté par les branches verticales de deux supports 12 et 13 en forme d'équerre, dont les branches horizontales portent des roues dentées, dont la rotation peut être bloquée, et qui engrènent avec deux crémaillères longitudinales. Ces crémaillères (non visibles sur la figure 1) sont montées au-dessous de deux plaques horizontales 16 et 17 solidaires des poutres 1 et 2, et peuvent coulisser longitudinalement de quelques millimètres sous ces plaques. La commande manuelle 14, qui agit sur les roues dentées, et ce simultanément des deux côtés de la station grâce à la tringle 18, permet de déplacer longitudinalement le rail mobile 11 pour adapter sa position à la longueur d'une planche supérieure d'éjection. Une paire de ressorts sous compression permanente, dont l'un, le 15, est visible sur la figure 1, sont montés longitudinalement respectivement sur les plaques 16 et 17. Chaque ressort, dont une extrémité est solidaire de la plaque, exerce une poussée avec son autre extrémité sur un bloc 22 solidaire d'une des crémaillères et pousse celle-ci vers l'avant de la station, et par conséquent serre l'outil supérieur entre les rails 5 et 11.The movable posterior rail 11 is carried by the vertical branches of two brackets 12 and 13 in the shape of a square, whose horizontal branches bear gears, whose rotation can be blocked, and which meshes with two longitudinal racks. These racks (not visible in Figure 1) are mounted below two horizontal plates 16 and 17 integral with beams 1 and 2, and can slide longitudinally a few millimeters under these plates. The manual control 14, which acts on the gears, and this simultaneously on both sides of the station thanks to the rod 18, allows longitudinally moving the movable rail 11 to adapt its position to the length of an upper ejection board. A pair of springs under permanent compression, one of which, the 15, is visible in Figure 1, are mounted longitudinally respectively on the plates 16 and 17. Each spring, one end of which is integral with the plate, exerts a thrust with its other end on a block 22 secured to one of the racks and pushes this one towards the front of the station, and consequently clamps the upper tool between the rails 5 and 11.

Deux vérins 19 et 20, montés sur une poutre transversale 24 fixe, solidaire du bâti de la machine par deux pattes de fixation 25 et 26 et par une poutre transversale 27, peuvent être mis en action par l'opérateur lorsque le châssis qui porte l'outil supérieur d'éjection est en position haute. Les vérins 19 et 20 portent une barre transversale 21. Lorsque le châssis porte-outil est en position haute, les blocs 22 viennent au niveau des extrémités de la barre transversale 21, de sorte que sous l'action des vérins, la barre 21 pousse sur un prolongement des blocs 22 dépassant des poutres 1 et 2, contrecarrant la poussée des ressorts 15 et libérant l'outil supérieur, qui peut alors être retiré facilement par l'opérateur.Two cylinders 19 and 20, mounted on a transverse beam 24 fixed, secured to the frame of the machine by two fixing lugs 25 and 26 and by a beam 27, can be activated by the operator when the frame that carries the upper ejection tool is in the up position. The cylinders 19 and carry a cross bar 21. When the tool carrier is in high position, the blocks 22 come at the ends of the bar transverse 21, so that under the action of the jacks, the bar 21 pushes on an extension of the blocks 22 protruding beams 1 and 2, counteracting the pushing the springs 15 and releasing the upper tool, which can then be removed easily by the operator.

On peut observer que les supports 12, 13 du rail mobile, les crémaillères, les ressorts 15 et les vérins 19, 20 sont agencés symétriquement par rapport à un plan vertical passant par un axe longitudinal central communément appelé "axe-machine".It can be observed that the supports 12, 13 of the movable rail, the racks, the springs 15 and the cylinders 19, 20 are arranged symmetrically with respect to a vertical plane passing through a central longitudinal axis commonly called "machine axis".

On voit également sur la figure 1 une poutre d'appui 23. Cette poutre 23 est amovible. Elle est destinée à appuyer sur le dessus d'une planche supérieure d'éjection pour maintenir la planéité de celle-ci pendant les montées et des descentes du châssis porte-outil.FIG. 1 also shows a support beam 23. This beam 23 is removable. It is intended to press on the top of a board superior ejection to maintain the flatness of it during the climbs and descents of the tool frame.

La station de séparation de poses peut être équipée du même châssis porte-outil.The separation station can be equipped with the same chassis toolbox.
