Definitions

  • the present invention relates to a cloth gripping device that is used in industrial plants, such as laundries, that process pieces of cloth, and that can grasp a single piece of cloth from among a plurality of pieces of cloth in a pile.
  • gripping members for grasping a large segment of a piece of cloth when distal ends of levers are opened and closed; and either small levers for sliding up and down between said gripping members and grasping a small segment of a piece of cloth when distal ends are opened and closed, or a suction tube for lifting a piece of cloth using suction.
  • the small levers are moved downward between the gripping members, and when the distal ends of the small levers lightly contact the surface of a piece of cloth, and they close and grasp a small portion of the cloth; or the suction tube is moved downward between the gripping members, and when the distal end of the suction tube lightly contacts the surface of a piece of cloth, suction is employed to lift the cloth. Thereafter, the small levers or the suction tube being moved upward, the single piece of cloth is separated from the other pieces that are piled up and hangs suspended. Then, when the upward movement of the small levers or the suction tube is halted, the levers of the gripping members close and the distal ends grasp a large segment of the piece of cloth and hold it suspended.
  • small tweezer-shaped levers 4 are provided between gripping members 2, and are moved up and down by an elevation unit 3, which is constructed using a cylinder, a link and a cam.
  • the width of the opening of the nippers 5 is more than twice (normally 0.6 to 0.7 mm) the thickness of the piece of cloth 1.
  • the gripping members 2 are so located that they enclose the piece of cloth 1 that is grasped by the nippers 5, as well as the nippers 5, and the distal ends of the levers of the gripping members 2 are opened and closed by a large chuck unit 7, which as constructed uses air, a cam and a solenoid.
  • the gripping members 2 are moved above a pile of pieces of cloth 1, and are halted at a predetermined position above one piece of cloth 1. Then, the distal ends of the gripping members 2 are opened and the small levers 4 descend between the gripping members 2. The nippers 5 at the distal ends of the small levers 4 are halted at a position where they are in contact with the surface of the topmost piece in the pile of pieces of cloth 1.
  • the nippers 5 at the distal ends of the small levers 4 are then closed, and grasp the surface of the piece of cloth 1. While holding the piece of cloth 1, the small levers 4 are lifted, the nippers 5 being moved upward through the opening between the distal ends of the gripping members 2.
  • the large chuck unit 7 is activated to close the levers of the gripping members 2.
  • the gripping members 2 grasp a portion of the piece of cloth 1 below the top that is held by and is hanging from the nippers 5, and hold the piece of cloth 1 suspended.
  • the nippers 5 at the distal ends of the small levers 4 are opened to release the piece of cloth 1 therefrom.
  • the gripping members 2 are employed to grasp a large portion of the piece of cloth 1.
  • a suction tube 8 that is raised and lowered by an elevation unit 3 is provided inside gripping members 2, the distal ends of levers of which are opened and closed by a large chuck unit 7.
  • the suction tube 8 is connected to a vacuum chamber 10, which is connected to a suction device.
  • a solenoid valve 9 is provided between the suction tube 8 and the vacuum chamber 10.
  • the gripping members 2 are halted at an appropriate position above a pile of pieces of cloth 1, and the distal ends of the levers of the gripping members 2 are opened.
  • the suction tube 8 is lowered between the gripping members 2, and contacts the surface of a piece of cloth 1.
  • vacuum to produce suction at the suction tube 8 only a topmost piece of cloth 1 is lifted from the pile of pieces of cloth 1 and is attached to the tube 8.
  • the distal ends of the levers of the gripping members 2 are closed and grasp a large portion of the piece of cloth 1, which is hanging from the suction tube 8, and hold it suspended.
  • the solenoid valve 9 is then closed to halt the suction at the suction tube 8, and the piece of cloth 1 is released from the suction tube 8.
  • the thus structured present invention provides the following effects.
