Definitions

  • the subject of the present invention is a head to equip a robot arm intended to perform a deflashing or roughing operation.
  • a certain number of items made of synthetic material and obtained by molding exhibit, after demolding, flash at the parting line. This is the case in particular of the soles of footwear made of injection-molded synthetic material which may be overmolded onto the item of footwear or bonded thereto. The removal of these protruding parts is performed by manual cutting as often as not. It is also known practice for deflashing to be performed using a head mounted at the end of the arm of a robot, the computer controlling the robot having incorporated the path of the machining head and the work that the tool is to perform. However, in existing devices, the mechanism employed is complicated and is cantilevered with respect to the end of the robot arm.
  • the tool consisting of shears
  • the tool is made to follow different paths, for example to pivot through 90° in the same continuous movement in order, for example, to cut off flash at the front and rear ends, which is perpendicular to the flash located around the periphery of the sole.
  • the object of the invention is to provide a head for equipping a robot arm, intended to perform a deflashing or roughing operation, and which solves the technical problems presented previously.
  • the head to which the invention relates comprises:
  • the working head can therefore pivot about the shaft on which its support is mounted to pivot, under the action of the actuator mounted on the same axis.
  • the number of components used is lower, and the masses are small and are centered in the extension of the axis of the actuator.
  • the actuator for driving the link rod is a rotary actuator.
  • the link rod for adjusting the orientation of the tool acts on the tool support via a compensation actuator.
  • the compensation actuator makes it possible to exert a determined and constant pressure on the workpiece, thus compensating for the effects of gravity, depending on the working position of the head.
  • this head comprises an electric motor positioned along the axis of the shaft, at the opposite end to the actuator for adjusting the position of the tool support, the output shaft of the motor being equipped with an eccentric acting on a link rod for driving the moving blade of a pair of deflashing shears.
  • the motor is located at the opposite end to the rotary actuator with respect to the tool support, so that the masses of the actuator and of the motor respectively are balanced with respect to the end of the arm of the actuator.
  • this head comprises an electric motor secured to the support of axis perpendicular to the shaft, on which the support is mounted to pivot, and onto the output shaft of which a roughing wheel is keyed.
  • FIG. 1 is a perspective view of a deflashing head.
  • FIG. 2 is an elevation in part section of the deflashing head of FIG. 1 .
  • FIG. 3 is an elevation in part section, similar to FIG. 2 , of a roughing head.
  • the head depicted in FIGS. 1 and 2 is mounted at the end of a robot arm 2 , to which it is fixed via a plate 3 .
  • a shaft 4 is mounted on this plate 3 parallel to the plane of the plate, and on this shaft there is mounted so that it can pivot a support 5 for a tool consisting of shears 6 .
  • Mounted on the shaft 4 and coaxial with the shaft 4 is a motor 7 which, via an eccentric 8 , drives a link rod 9 which actuates the moving blade 10 of the pair of shears 6 , the other blade 13 of which is fixed.
  • a rotary actuator 14 which drives a link rod 15 the other end of which is associated with the support 5 by way of a compensation actuator 16 .
  • the shears 6 are centered on the robot arm.
  • the orientation of the tool consisting of the shears 6 is given by the rotary actuator 14 which causes the link rod 15 to pivot to a greater or lesser extent, the actuator 16 being intended to ensure constant pressure on the workpiece irrespective of the position of the assembly in space.
  • FIG. 3 depicts a roughing head, adopting the same overall geometry, in which the same elements are denoted by the same references as before.
  • the support 5 is equipped with an electric motor 18 , to the output shaft 19 of which a roughing wheel 20 is fixed.
  • the orientation of the working axis of the wheel is given by the action of the rotary actuator 14 by way of the link rod 15 .
  • the invention provides a vast improvement over the existing art by providing a head to equip a robot arm, of simple and compact structure, allowing a wide freedom of movement, the compactness and the centering of the weights allowing rapid movements which are not disturbed by the presence of a significant amount of inertia.
  • the support 5 could be equipped with a gripper intended, if the flash is significant in extent, to make a V-shaped incision into the flash, before the flash is cut off using the shears, it being possible for another gripper, also mounted on the support 5 , to be provided in order to take hold of the flash at the end of cutting and allow its transfer, via movement of the robot, into a waste receptacle.
