Description

  

      Disposifif        préhenseur       Le présent brevet a pour objet un dispositif       préhenseur    à commande     électromagnétique        suscepti-          ble    d'être     utilisé        d'ans    de     multiples    cas, par exemple  pour le     transport    -de plaques de tôle.  



  Ce dispositif     préhenseur    est     caractérisé    par le     fait     qu'il comprend une ventouse     élastique    dans le fond  de laquelle débouche un passage permettant de mettre  en communication     l'espace        limité    par ce     fond    avec  l'atmosphère, et une soupape     électromagnétique    dont  l'organe mobile, selon sa position, ouvre ou obture  de façon étanche ledit passage.  



  Un des     principaux        avantages    de ce dispositif est  de pouvoir être commandé automatiquement ou à       distance.     



  La figure unique du dessin ci-annexé représente,  en     coupe    axiale, une forme d'exécution de l'objet de  l'invention, donnée à titre d'exemple.  



  Le     dispositif    représenté est constitué par un bâti  10, par une ventouse élastique 11 et par une soupape  électromagnétique 12.  



  Le bâti 10, dans lequel est disposée la soupape  12, est formé par une cloche cylindrique 13 et par  une plaque     circulaire    14 venue d'une pièce avec un  ajutage 15 et     avec        une    portée     cylindrique    filetée 16  vissée dans un taraudage de la jupe de la cloche 13.  



  Le corps élastique 17 de la ventouse 11 est  monté à force, par sa base     annulaire,    sur le pourtour  de l'ajutage 15 dont l'orifice forme un passage 18  mettant en communication l'espace     limité    par le fond       die    la ventouse et l'atmosphère extérieure. Ce passage  est normalement obturé, pour permettre à la ven  touse de saisir un objet, comme une ventouse élas-    tique ordinaire, par l'organe     mobile    de la soupape qui  est constitué par un pointeau 19 vissé à l'extrémité  du noyau 20 de     l'électro-aimant    de commande de la  soupape. Ce     pointeau    est     appliqué    contre son siège  21 par un ressort 22.  



  L'armature     cylindrique    23 de l'électro-aimant de       commande,    à     l'intérieur    de laquelle est montée la       bobine    24, est fixée par des     vis    25 à la base de la  cloche 13. Les bornes de     cette    bobine apparaissent  en 26.  



  Pour poser un objet saisi par la ventouse, on       excite        l'électro-aimant    dont le noyau 20 plonge à  l'intérieur de la     bobine    24, à l'encontre de l'action  du ressort 22, en     entraînant    le     pointeau    19 qui ouvre  le passage 18 par     lequel    une pression normale se  rétablit dans la chambre de la ventouse. Dès. la cou  pure du     courant    d'excitation de     l'électro-aimant    et  le retour du pointeau 19 contre son siège 21, le dis  positif est prêt à saisir un nouvel objet.



      Gripping device The present patent relates to an electromagnetically controlled gripping device capable of being used in many cases, for example for the transport of sheet metal plates.



  This gripping device is characterized by the fact that it comprises an elastic suction cup in the bottom of which opens a passage allowing the space limited by this bottom to be placed in communication with the atmosphere, and an electromagnetic valve, the movable member of which, depending on its position, opens or seals said passage.



  One of the main advantages of this device is that it can be controlled automatically or remotely.



  The single figure of the appended drawing represents, in axial section, an embodiment of the object of the invention, given by way of example.



  The device shown is constituted by a frame 10, by an elastic suction cup 11 and by an electromagnetic valve 12.



  The frame 10, in which the valve 12 is disposed, is formed by a cylindrical bell 13 and by a circular plate 14 integrally fitted with a nozzle 15 and with a threaded cylindrical bearing surface 16 screwed into an internal thread of the skirt of the bell 13.



  The elastic body 17 of the suction cup 11 is force-mounted, by its annular base, on the periphery of the nozzle 15, the orifice of which forms a passage 18 putting in communication the space limited by the bottom of the suction cup and the outdoor atmosphere. This passage is normally closed, to allow the vent to seize an object, such as an ordinary elastic suction cup, by the movable member of the valve which is constituted by a needle 19 screwed to the end of the core 20 of the valve. 'valve control electromagnet. This needle is applied against its seat 21 by a spring 22.



  The cylindrical armature 23 of the control electromagnet, inside which the coil 24 is mounted, is fixed by screws 25 to the base of the bell 13. The terminals of this coil appear at 26.



  To place an object gripped by the suction cup, the electromagnet, the core 20 of which plunges inside the coil 24, is energized, against the action of the spring 22, by driving the needle 19 which opens the passage 18 through which normal pressure is reestablished in the chamber of the suction cup. From. the pure neck of the excitation current of the electromagnet and the return of the needle 19 against its seat 21, the positive dis is ready to seize a new object.
