Definitions

  • This invention relates to an article transfer mechanism more particularly to a mechanism for transferring an article from one position or work station to another, 5. and also if desired to transferring an article sequentially from one work station or position to another.
  • an article transfer mechanism including. a member attached to the core of an electromagnet, means mounting the member by strap means extending in an inclined direction, all straps being inclined in the same direction around the body, the straps being inclined at an angle 20. to the axis of the coil and attached to either the coil, base, or other structure fixed relative to the coil.
  • One or more arms are provided to project from the body, preferably in a direction away from the axis of the body either in a radial or inclined direction.
  • FIG. 1 is a plan view of the mechanism.
  • FIG. 2 is a perspective view thereof in the extended 5. position and
  • FIG. 3 is a perspective view of an alternative embodiment in the lower position.
  • the article transfer mechanism comprises a base 1 to 10. hold the electromagnet 2, the coil 3 being mounted in the base 1 with the coil 4 extending therefrom.
  • a shaft 5 carrying at its upper end a mounting 6 to which are attached radial arms 7.
  • the number of radial arms 7 can vary, 15. one pair of arms being shown for clarity.
  • the base 1 and the mounting 6 there are provided a series of resilient rods of spring steel or the like.
  • the rods are mounted on the base 1 and each is inclined across the base in an upward direction
  • the rods being inclined in the same anticlockwise or clockwise direction. As shown the rods are attached to the base adjacent one corner and extending in an upward direction and are inclined towards the centre of the mechanism to be attached
  • the rods are rigidly mounted in the base, and at their upper ends connected by a coil spring 9 to the mounting, the rods being so arranged that in the rest position the rods hold the mounting and thus the core 5. of the electromagnet in the upper position.
  • the electromagnet When the electromagnet is actuated to move the core downwardly as shown in FIG. 3, the core and mounting move downwardly, but due to the resilient rods, these will bend and flex to cause a partial rotary movement.
  • the springs 9 10. allow the acute bending to take place at the ends of the rods 8 without reducing severe stresses in the rods 8 adjacent the mounting 6.
  • the springs On deactivation of the electromagnet, the springs cause the member 6 and the core 5 to move upwardly again 15. with a partial rotary motion in the opposite direction to the partial rotary motion in the downward direction to return the mounting 6 and core to the rest position.
  • the suction can be obtained from a vacuum system connecting to vacuum line 11 controlled by a suitable valve 12, either by the movement of the arm or body itself or
  • grippers, fingers, claws or the like depending upon the article being transferred can be provided at the end of each arm these being operated pneumatically, hydraulically, or mechanically and controlled 5. by suitable actuating valves, levers, switches or the like.
  • the arm 7 could be articulated at . 13 and at its end operate in a suitable guide so that the arm would partake of a partial rotary motion without any vertical motion.
  • This motion could also be provided by guides or 15. slides so that the end of the arm at its pick up station could be provided with a slight downward movement or an extendible movement to grasp the article.
  • Length and movement of the arms can be controlled by suitably adjusting the length of the rods and the inclination of the rods to achieve the desired movement 25. and this can also be achieved by controlling the length of the stroke of the metallic core of the electromagnet.
  • the length of stroke, and the frequency of operation of the electromagnet can be controlled and varied as desired by known electronic circuitry.
  • the mechanism can be used for transferring one article from one station to another or alternatively a plurality of arms can be provided so that the articles are transferred sequentially from 5. one station to another, a performing operation being provided on the article during the return stroke of the mechanism.
  • rods are metal rods, it is to be realized that other materials may be used, such as fibreglass rods or straps, or straps

Abstract

Un mécanisme de transfert d'objets d'une position à une autre comprend des bras (7) pour saisir les objets, ces bras étant montés sur le noyau mobile (4) d'un électroaimant (2). Les bras sont connectés par des dispositifs élastiques inclinés (8, 9) à une base (1), de sorte qu'ils effectuent un mouvement axial par rapport à l'électroaimant associé à un mouvement partiellement rotatif autour de l'axe de l'électroaimant.
