Description
La présente invention a pour objet un dispositif pour la manipulation de plaques perforées, telles que, notamment, des tôle9 poinçonnées, des plaques de circuits imprimés, etc. The present invention relates to a device for handling perforated plates, such as, in particular, punched sheet metal9, printed circuit boards, etc.
On sait qu'à l'heure actuelle, les poinçonneuses à commande numérique comportent des systèmes de manipulation et de transport des plaques poinçon- nées. Ces systèmes connus peuvent entre - soit des dispositifs magnétiques, comportant un ou plusieurs aimants - soit des dispositifs à pinces ou à griffes - soit des systèmes pneumatiques comportant une pluralité de ventouses. It is known that at present, punching machines with numerical control include systems for handling and transporting punched plates. These known systems can be between - either magnetic devices, comprising one or more magnets - or clamp or claw devices - or pneumatic systems comprising a plurality of suction cups.
C'est à ce dernier type de moyen de manipulation et de transfert que se réfère la présente invention. Les systèmes pneumatiques réalisés actuellement comportent nécessairement une distribution programmée de la mise sous vide des différentes ventouses, de maniere à interrornpre automatiquement la mise sous vide de la ou des ventouses situées en regard de l'une des perforations de la plaque. En effet, en l'absence d'une telle programmation, l'effet du vide cesserait immédiatement dans toutes les ventouses, ce qui mettrait hors service le dispositif de manipulation. It is to this latter type of handling and transfer means that the present invention refers. The pneumatic systems currently produced necessarily include a programmed distribution of the vacuuming of the different suction cups, so as to automatically interrupt the vacuuming of the suction cup or suction cups located opposite one of the perforations in the plate. Indeed, in the absence of such programming, the effect of the vacuum would immediately cease in all the suction cups, which would put the handling device out of service.
On utilise généralement un système logique pneumatique pour réaliser la programmation de la commande de mise sous vide des différentes ventouses pneumatiques. On conçoit que de tels systèmes pneumatiques sont compliqués, et, par conséquent, coûteux et délicats 'a mettre en oeuvre et à entretenir. A pneumatic logic system is generally used to carry out the programming of the vacuum control of the various pneumatic suction cups. It will be appreciated that such pneumatic systems are complicated, and therefore expensive and difficult to implement and maintain.
Par conséquent, l'invention se propose d'apporter un moyen de manipu- lation pneumatique peu coûteux et fiable. A cet effet, elle concerne un dispositif de manipulation et de transfert pneumatique de plaques perforées telles que, par exemple, des toles poinçonnées, des plaques de circuits imprimés, etc., caractérisé en ce qu'il est constitué par une plaque d'un matériau élas- tique, par exemple une matière plastique, et plus particulièrement un élastomère, comportant une pluralité d'alvéoles munis de conduites d'aspiration sé parées reliées à une source de vide, disposés sur la surface extérieure de ladite plaque, devant servir de surface de préhension pour la plaque perfore å manipuler, chaque alvéole comportant un moyen pour interrompre la communication entre l'alvéole et la conduite de mise sous vide, lorsqu'un alvéole quelconque se trouve en regard d'une perforation de ladite plaque à manipuler et transporter. Consequently, the invention proposes to provide an inexpensive and reliable means of pneumatic handling. To this end, it relates to a device for pneumatically handling and transferring perforated plates such as, for example, punched sheets, printed circuit boards, etc., characterized in that it consists of a plate of a elastic material, for example a plastic material, and more particularly an elastomer, comprising a plurality of cells provided with separate suction lines connected to a vacuum source, arranged on the external surface of said plate, to be used as gripping surface for the perforated plate to be handled, each cell comprising means for interrupting the communication between the cell and the vacuum line, when any cell is opposite a perforation of said plate to be handled and carry.
Selon l'invention, le mayen servant à interrompre la communication entre l'alvéole et sa conduite de mise sous vide consiste en une membrane mince et élastique, percée d'une pluralité de trous, positionnée contre la surface extérieure de ladite plaque en matériau élastique, de manière que la par. According to the invention, the mayen used to interrupt the communication between the cell and its vacuum line consists of a thin and elastic membrane, pierced with a plurality of holes, positioned against the outer surface of said plate of elastic material , so that s.
tic de ladite membrane située en regard d'une perforation de la plaque à manipuler soit aspirée par l'effet du vide et vienne se plaquer contre la conduite de mise sous vide de l'alvéole correspondant, en obturant cette conduite.tic of said membrane located opposite a perforation of the plate to be handled is sucked in by the effect of the vacuum and comes to press against the vacuum line of the corresponding cell, closing this line.
Selon une variante de cette invention, le moyen interrompant la communication entre l'alvéole et sa conduite de mise sous vide est constitué par un clapet anti-retour, disposé au débouché de ladite conduite dans l'alvéole considéré. According to a variant of this invention, the means interrupting the communication between the cell and its vacuum line consists of a non-return valve, disposed at the outlet of said line in the cell in question.
D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après, en référence au dessin annexé, qui en illustre deux exemples de réalisation dépourvus de tout caractère limitatif. Sur le dessin
- la Figure 1 est une vue schématique, -en élévation, représentant un premier exemple de réalisation d'un dispositif selon l'invention;
- la Figure 2 est une vue partielle, similaire à la Figure 1, mais à plus grande échelle, illustrant le fonctionnement du dispositif selon l'invention; et,
- la Figure 3 est une vue partielle, à échelle agrandie, illustrant une variante de l'invention.Other characteristics and advantages of this invention will emerge from the description given below, with reference to the appended drawing, which illustrates two exemplary embodiments thereof which are in no way limiting in nature. On the drawing
- Figure 1 is a schematic view, -in elevation, showing a first embodiment of a device according to the invention;
- Figure 2 is a partial view, similar to Figure 1, but on a larger scale, illustrating the operation of the device according to the invention; and,
- Figure 3 is a partial view, on an enlarged scale, illustrating a variant of the invention.
On se réfère en premier lieu aux Figures 1 et 2, qui représentent un premier exemple de réalisation de l'invention. Reference is firstly made to FIGS. 1 and 2, which represent a first embodiment of the invention.
Dans cette réalisation, le système de manipulation de la tôle poinçonnée 10 se compose d'une plaque 12, constituée d'un matériau élastique, mais suffisamment rigide cependant, par exemple d'une matière plastique, et plus particulièrement d'un élastomère, qui comporte, sur sa surface extérieure, une pluralité d'alvéoles tels que 14. Chaque alvéole 14 est relié à une source de vide, unique pour tous les alvéoles (non représentée sur le dessin), par l'intermédiaire d'une conduite telle que 16. La plaque 12 est montée dans un support 18, déplaçable par tout moyen approprié. In this embodiment, the system for handling the punched sheet 10 consists of a plate 12, made of an elastic material, but sufficiently rigid however, for example of a plastic material, and more particularly of an elastomer, which comprises, on its outer surface, a plurality of cells such as 14. Each cell 14 is connected to a vacuum source, unique for all the cells (not shown in the drawing), by means of a pipe such as 16. The plate 12 is mounted in a support 18, movable by any suitable means.
Sur la surface de la plaque 12 munie des alvéoles 14, on dispose une membrane souple 20, par exemple en caoutchouc, percée d'une pluralité de trous, comme on peut le voir sur les Figures 1 et 2. On the surface of the plate 12 provided with the cells 14, there is a flexible membrane 20, for example made of rubber, pierced with a plurality of holes, as can be seen in FIGS. 1 and 2.
Le fonctionnement de ce système est le suivant
Le dispositif est amené en regard de la plaque perforée 10 à soulever et u transporter, et on l'applique contre cette plaque 10 de façon que sa face munie des alvéoles 14 vienne appuyer contre la plaque 10 à manipuler. On fait le vide par l'intermédiaire des conduites 16. S'il n'existe pas de perforations de la plaque perforée 10 en regard d'une perforation de la membrane (partie de gauche de la Figure 2), la dépression due au vide s'exerce sur la plaque 10, qui est plaquée contre le dispositif.Aux endroits Qù il existe une perforation de la plaque 10 en regard d'une ou plusieurs perforations de la membrane 20 (partie de droite de la Figure 2), la membrane se soulève (22, sur la Figure 2) sous l'effet du vide et obture la conduite 16 correspondante. Grâce à cette caractéristique, l'effet du vide s'exerce toujours sur la plaque perforée 10 à manipuler. The operation of this system is as follows
The device is brought opposite the perforated plate 10 to be lifted and transported, and it is applied against this plate 10 so that its face provided with the cells 14 comes to press against the plate 10 to be handled. Vacuum is created through the pipes 16. If there are no perforations in the perforated plate 10 opposite a perforation in the membrane (left part of FIG. 2), the vacuum due to the vacuum is exerted on the plate 10, which is pressed against the device. In places where there is a perforation of the plate 10 opposite one or more perforations of the membrane 20 (right part of Figure 2), the membrane lifts (22, in Figure 2) under the effect of vacuum and closes the corresponding pipe 16. Thanks to this characteristic, the effect of the vacuum is always exerted on the perforated plate 10 to be handled.
Dans la variante illustrée schématiquement par la Figure 3F la membrane 10 est supprimée, et on dispose un clapet anti-retour en regard de chaque conduite 16', reliee à la source sous vide, ce clapet anti-retour pouvant etre constitué, de façon connue, par une bille 24 maintenue dans une cage. In the variant illustrated schematically in Figure 3F the membrane 10 is omitted, and there is a non-return valve opposite each pipe 16 ', connected to the vacuum source, this non-return valve can be constituted, in known manner , by a ball 24 held in a cage.
Bien entendu, l'invention n'est pas limitée aux exemples de réalisation décrits et représentés, mais elle en englobe toutes les variantes. Ainsi, la plaque 12 peut etre réalisée sous la forme d'un tapis transporteur Of course, the invention is not limited to the embodiments described and shown, but it encompasses all variants. Thus, the plate 12 can be produced in the form of a conveyor belt
