Abstract: A system for repositioning row bars includes a base support including a top surface, and a support arm positioned on the top surface and configured to rotate from a first position to a second position, a tray assembly coupled to the support arm, the tray assembly including a first tray including a plurality of first channels, each configured to retain one of the row bars in an initial position, a transfer substrate including a plurality of transfer channels, each configured to receive one of the row bars from the first tray as the support arm moves from the first position to the second position, and a second tray including a plurality of second channels, each configured to retain the one of the row bars in a final position, where the row bars in the final position are rotated by a preselected number of degrees from the initial position.

Abstract: An intermediate guide member is provided attachable and removable between a head portion and a supporting frame of a stocker for printing plates. A number of intermediate guide members is an element to set a time of starting downward movement of hooks supporting a leading end of a printing plate. Three conditions in accordance with lengths of non-detection times are set for detecting the printing plate to judge authenticity of the detection. When the hooks reach vicinities of stoppers provided at supporting bars of a reversal unit, the hooks swing, are pulled-in from above the slope, and transfer the printing plate to the stoppers. Thereafter, by rotating the supporting bars and the stoppers integrally around a shaft, the printing plate is pivoted over toward a back plate, and a lower end of the printing plate is transferred from the stoppers to a receiving plate without damaging the printing plate.

Abstract: The present invention relates to an apparatus for turning the top side of planar objects (1, 2) such as plywood or particle boards into the underside, the apparatus comprising an importing conveyor and an exporting conveyor, and a board turner assembly mounted between the conveyors. The board turner is formed by at least two sets of turning fingers (5, 6), each one of the sets having its fingers aligned in the same plane and being adapted to rotate about a common axis parallel with said plane. The construction of the conveyors is such that it permits the fingers (5, 6) during their rotary motion to pass through gaps of the conveyors. Each one of said sets of turning fingers (5, respectively 6) are arranged to be turned independently from each other.

Abstract: An inertial force applied to a motor drive shaft when jaw members stop at opening and closing ends, grasping positions of a workpiece, and the like is absorbed and damage to motor parts such as gears due to impact is prevented.

Abstract: A work support which assists in the inversion of a large workpiece has a supporting frame and a top frame. The top frame is provided with an intermediate hinge and an end hinge along at least one end, so as to be collapsible, and the leg of the supporting frame is hinged along the opposite end. The workpiece can be moved to one side of the intermediate hinge and the top frame can be collapsed, lowering the center of gravity of the workpiece and standing it partially on edge. One or two workers can then easily shift the workpiece over to the other side of the top frame. When the top frame is raised back to a horizontal position the work surface is in an inverted condition, exposing unfinished surfaces for finishing. In the preferred embodiment the top frame is provided with a flexible membrane overlaying the intermediate hinge. When the top frame is collapsed the membrane curls upwardly and forms a cushion which supports the edge of the workpiece, and thus assists in the inversion process.

Abstract: A system for manipulating articles, such as irregular mailpieces in the U.S. Postal Service mail processing system, receives an agglomeration of parcels into a first subsystem where the parcels are separated and are passed to a second subsystem where each parcel is manipulated until its addressee label is directed upward. The first subsystem includes a plurality of individually rotatable cylindrical rollers which form a support surface for the parcels. The rollers produce translation of a parcel by cooperative motion or separation of parts of a pile of parcels by differential motion. The second subsystem includes a high-friction, flexible conveyor belt which in a first mode supports a parcel and in a second mode forms a downward loop in which a parcel can be rotated and inverted. The parcels in both subsystems are manipulated by a five-axis robotic arm which is responsive to a machine vision system measuring the position and physical characteristics of each parcel.

Abstract: A machine is positioned in the line of a gypsum board manufacture to provide lifting arms, which are actuated up through the line to remove board sections, invert and transfer them to an adjacent area for subsequent drying. The lifting arms are reciprocated, end for end, during the elevating and inverting action to subsequently approach the board from beneath. The lifting arms are actuated through slider boxes, attached to a shaft, and a cam is provided to control the ends of the lifting arms, as each end is pivoted at the inverter shaft to which its slider box is attached.
