  • Patent number: 7871236
    Abstract: A powered paper turner is an automated load turning device specifically designed to turn a paper stack sandwiched between a pair of pallets in a work and turn printing process. The paper turner is mounted on wheels, with a rotating module rotating about an axle mounted on a moving support beam to give the module its rotational capability. A slide that secures the paper stack moves horizontally within the rotating module to shift the center of gravity. As the support beam moves up and down a pair of guide rods on linear bearings, the rotating module rotates about the axle. During a downstroke of the moving support beam, the paper stack rotates from a vertical position to a horizontal position. The stack is then shifted, so that during an upstroke of the moving support beam, the paper stack completes a 180° rotation.

  • Patent number: 7341421
    Abstract: This application relates to a self-contained apparatus for mechanically turning individual workpieces travelling on a conveyor, such as lengths of lumber travelling into or exiting from a sawmill. The invention reduces the need for lumber graders to turn lumber manually and thereby helps avoid repetitive motion injuries. The apparatus includes an adjustable height frame which is positionable alongside the conveyor. The frame supports a workpiece holder defining an open-ended slot for temporarily receiving an end portion of a workpiece. When the end of a lumber board or other workpiece is received within the holder, a proximity sensor causes the holder to rotate, thereby turning the workpiece lengthwise 180 degrees. The workpiece is then deposited on to the conveyor in its inverted orientation for further travel thereon. The apparatus may also optionally permit workpieces to pass through the holder when a “skip” rather than an “invert” signal is received.

  • Patent number: 4838751
    Abstract: In a method of and a system for unpacking bales each tied by at least one strap, a contact plate member provided with a strap sensor unit is mounted, through a biasing arrangement, on a body frame for movement relative thereto. The body frame is moved toward a confronting side face of the bale to bring the contact plate member into contact with the side face of the bale. The body frame is further moved toward the bale while increasing biasing force of the biasing arrangement, until contact pressure, with which the contact plate member is urged against the side face of the bale, reaches a predetermined value. When the contact plate member is urged by the bale in such a direction as to increase the biasing force during scanning of the strap sensor unit along the side face of the bale, the body frame is moved away from the bale to maintain the contact pressure at the predetermined value.

  • Patent number: 4725087
    Abstract: A double-hand apparatus for an industrial robot, in which a first and second hand are mounted on a common frame. Two supporting arms are pivotally supported at respective ends on a pair of rotary shafts on the common frame and at their other ends at two respective points on a base such that the two arms extend parallel to each other so as to constitute a parallel link. At least one of the supporting arms is pressed at one end by an energizing spring. Thereby the two supporting arms in a normal state are held in a predetermined parallel link attitude by the spring force by the energizing spring. When either the first or the second hand receives a reaction force from a workpiece that is being set on a table, this reaction force deforms the parallel link of the supporting arms against the force of the energizing spring to thereby lessen the effect of the reaction force.
