  • Patent number: 4934504
    Abstract: Angular regions (A, B) for turning a trunk body (12) of an industrial robot can be changed in accordance with an operation of the industrial robot by setting movable stoppers (18, 20). Turning movement can be stopped by an electrical means (LS1, LS2, LS3, LS4, LS5) to protect a drive motor and a drive mechanism, just before a stopper (22) fixed on the trunk body collides with mechanical stoppers (14, 16, 18, 20). An accident based on an error operation of the movable stoppers can be prevented by disposing proximity detectors (PS1, PS2, PS3, PS4).

  • Patent number: 4892242
    Abstract: A method and device are provided for separating trimming losses from a sheet having a plurality of products formed thereon with star-shaped scraps between the products. In one embodiment, the sheet is placed on a sheet supporting plate. The sheet is positioned between a blanking plate and a plurality of pushing rods fixed to a mounting plate. Each of the pushing rods has a piercing pin extending from the free end thereof for penetrating into a corresponding star-shaped scrap. The blanking plate has through holes formed therein which correspond to the pushing rods and star-shaped scraps such that the pushing rod passes through a corresponding through hole. The inner diameter of each through hole is smaller than the outer size or greatest dimension of the star-shaped scrap. When the star-shaped scrap is pushed through the through hole by the pushing rod, it deforms and passes through the through hole.
