Abstract

Ce préhenseur (PH) dont la pince (P) est formée par deux mors (M1, M2) oscillants se particularise par le fait que d'une part ces mors (M1-M2) sont solidaires en rotation de deux axes (AX1-AX2) tourillonnant dans des paliers (PA) portés par un châssis (CM) solidaire de la tige (TV) d'un vérin et que d'autre part la rotation de ces axes (AX1, AX2) est provoquée par le déplacement angulaire d'une pièce de manoeuvre (TG1-TG2) reliant chaque axe (AX1-AX2) à une partie fixe.This gripper (PH), the clamp (P) of which is formed by two oscillating jaws (M1, M2) is distinguished by the fact that on the one hand these jaws (M1-M2) are integral in rotation with two axes (AX1-AX2 ) swiveling in bearings (PA) carried by a frame (CM) integral with the rod (TV) of a jack and that on the other hand the rotation of these axes (AX1, AX2) is caused by the angular displacement of an operating part (TG1-TG2) connecting each axis (AX1-AX2) to a fixed part.

Description

L'invention se rapporte à un préhenseur particulièrement applicable à un dispositif dépileur et susceptible de prélever nappe après nappe, dans un matelas textile ou empilage similaire.The invention relates to a gripper which is particularly applicable to a destacking device and capable of removing ply after ply, from a textile mattress or similar stacking.

Ce préhenseur, comme celui décrit dans le FR-A-2.523.560 comprend une pince et des moyens pour ouvrir et fermer cette pince.This gripper, like that described in FR-A-2,523,560 comprises a clamp and means for opening and closing this clamp.

La pince revendiquée dans ce brevet comprend : une pièce centrale fixe pourvue latéralement et de chaque côté d'une partie élastique, deux branches se croisant pour constituer le bec de préhension, chacune des branches, de préférence dans le prolongement de la partie élastique étant pourvue d'une touche.The clamp claimed in this patent comprises: a fixed central part provided laterally and on each side with an elastic part, two branches crossing to form the gripping spout, each of the branches, preferably in the extension of the elastic part being provided a touch.

Les moyens d'ouverture-fermeture de cette pince sont constitués par deux doigts (un par branche) mobiles verticalement et pouvant venir périodiquement, dans leur position basse, appliquer sur lesdites touches en vue de déformer les parties élastiques et modifier le croisement des parties constitutives du bec.The opening-closing means of this clamp consist of two fingers (one per branch) movable vertically and being able to come periodically, in their low position, to apply on said keys in order to deform the elastic parts and modify the crossing of the constituent parts of the beak.

La présente invention propose un autre type de pince et d'autres moyens commandant son ouverture et sa fermeture.The present invention provides another type of clamp and other means controlling its opening and closing.

La pince est constituée par un châssis mobile en hauteur, solidaire de la tige d'un vérin, deux axes tourillonnant dans des paliers fixés à ce châssis, deux mors ayant des mouvements angulaires commandés par ces axes.The clamp consists of a chassis movable in height, integral with the rod of a jack, two axes journalling in bearings fixed to this chassis, two jaws having angular movements controlled by these axes.

Les moyens de manoeuvre sont deux jeux de tiges croisées dont les extrémités inférieures sont fixées chacune à l'un desdits axes et les extrémités supérieures articulées sur des points fixes du préhenseur, par exemple une platine.The operating means are two sets of crossed rods, the lower ends of which are each fixed to one of said axes and the upper ends articulated on fixed points of the gripper, for example a plate.

Le vérin de manoeuvre en écartant ou rapprochant le châssis mobile de cette platine, modifie la croisure des tiges ce qui fait tourner les axes et par voie de conséquence fait ouvrir ou fermer les mors.The actuating cylinder by spreading or bringing the movable frame closer to this plate, modifies the crossing of the rods which makes the axes rotate and consequently makes the jaws open or close.

D'autres particularités et avantages apparaîtront à la lecture de la description et des revendications qui suivent, faites en regard des dessins sur lesquels :

  • - la figure 1 représente, en élévation, le préhenseur objet de l'invention en position fermée ;
  • - la figure 2 est une vue identique du même préhenseur mais en position d'ouverture.
Other features and advantages will appear on reading the description and the claims which follow, made with reference to the drawings in which:
  • - Figure 1 shows, in elevation, the gripper object of the invention in the closed position;
  • - Figure 2 is an identical view of the same gripper but in the open position.

Comme on le voit sur ces figures, le préhenseur PH comporte une partie fixe verticalement constituée par la platine fixe PF de laquelle est solidaire, d'une part un vérin VR1 et d'autre part au moyen d'entretoises telles que ET et une seconde platine fixe PFS.As can be seen in these figures, the gripper PH comprises a vertically fixed part constituted by the fixed plate PF of which is integral, on the one hand a jack VR1 and on the other hand by means of spacers such as ET and a second fixed stage PFS.

De l'extrémité de la tige TV du piston VR1 est solidaire un châssis mobile CM portant deux axes AX1, AX2 tourillonnant dans des paliers PA fixés à ce châssis. De chaque axe (AX1 ou AX2) est solidaire un levier LV1 (ou LV2) fixé perpendiculairement à un mors M1 (ou M2).From the end of the TV rod of the piston VR1 is fixed a mobile chassis CM carrying two axes AX1, AX2 journalling in bearings PA fixed to this chassis. Each lever (AX1 or AX2) is joined to a lever LV1 (or LV2) fixed perpendicularly to a jaw M1 (or M2).

De chaque axe A1 (ou A2) est aussi angulairement solidaire une tige TG1 (ou TG2) dont l'autre extrémité est articulée sur la platine fixe PFS.Each axis A1 (or A2) is also angularly integral with a rod TG1 (or TG2), the other end of which is articulated on the fixed plate PFS.

Les tiges TG1 et TG2 se croisent, l'angle de leur point virtuel d'entablure pouvant varier selon la distance du châssis CM à la platine PFS.The rods TG1 and TG2 intersect, the angle of their virtual point of entablature can vary according to the distance from the chassis CM to the plate PFS.

L'articulation d chaque tige sur celle-ci est constituée par plot PO tournant par rapport à la partie fixe, en fonction de la variation de l'angle, fait par la tige avec la platine.The articulation of each rod thereon is formed by a stud PO rotating relative to the fixed part, depending on the variation of the angle, made by the rod with the plate.

Avantageusement, les mors (M1 et M2) sont réalisés par des pièces dont les profils vis-à-vis sont dentés.Advantageously, the jaws (M1 and M2) are produced by parts whose opposite profiles are toothed.

Pour passer de la position ouverte (Fig. 2) à la position de fermeture donc de préhension (Fig. 1), la tige TV sort du vérin VR1, mouvement qui écarte le châssis CM de la platine fixe PFS et modifie donc l'angle de l'entablure virtuelle des tiges TG1-TG2.To pass from the open position (Fig. 2) to the closed and therefore gripping position (Fig. 1), the TV rod comes out of the jack VR1, a movement which separates the chassis CM from the fixed plate PFS and therefore modifies the angle of the virtual entablature of the rods TG1-TG2.

La modification de cet angle n'est possible queChanging this angle is only possible
