Workpiece holder and workpiece transporting clamp

Abstract

The object of the invention is to facilitate fitting of a workpiece by a simple structure without largely increasing manufacturing cost, and prevent dropping of the workpiece even when external force is applied during conveyance. The work clamper 1, one end of a flexible plate 3 is overlapped with a rigid plate 2 and welded and fixed, and a workpiece W inserted from a free end 3a of the flexible plate 3 into a space between the rigid plate 2 and the flexible plate 3 is sandwiched by snapping force of the flexible plate 3. The free end 3a side of the flexible plate 3 is bent inwardly to make an acute angle, to form a hook-shaped cantilever of which portion from a tip 3b of the flexible plate 3 to the fixed end 3c side serves as a plate spring part 3d to energize the free end 3a to the rigid plate 2 side and of which portion from the tip 3b to the free end 3a serves as a turned part 3f for making a tip edge 3e of the flexible plate 3 bite into the workpiece W. To the rigid plate 2, a flat plate cantilever 4 for reinforcement to energize the plate spring part 3d from the top of the flexible plate 3 to the rigid plate 2 side is welded and fixed.

Description

technical field [0001] The present invention relates to a workpiece transfer jig for gripping a rib formed on the back side of a workpiece, conveying the workpiece, and a workpiece holder for fixing the workpiece thereon. Background technique [0002] Water pressure transfer printing is a surface decoration technology that transfers the printed pattern to the surface of the workpiece by immersing the workpiece in the water surface of a water-soluble film floating on the printed pattern, forming wood grain, leather, natural stone, etc. on the resin product. The pattern gives it a high-end feel. [0003] In this case, the workpiece is conveyed and submerged by a conveyor that moves on a hydraulic transfer tank or a robot that moves an arm on a prescribed track. However, since the workpiece cannot be directly fixed to the conveyor or the robot arm, it is fixed to a conveying jig, and the hydraulic transfer is performed while conveying the jig by a conveyor or robot.

Problems solved by technology

[0013] Recently, however, there have been cases where a water flow is generated in a hydraulic transfer tank to move the workpiece from the downstream side to the upstream side while performing water flow. Pressure transfer, because the relative speed of the workpiece W during hydraulic transfer is accelerated, so the water flow resistance is also increased. In the experiment, the workpiece W fell off in the hydraulic transfer tank

[0014] Therefore, a workpiece holder using a thicker plate and increased spring strength (rigidity) was trial-manufactured as the flexible plate 55, but it was found that loading and unloading the workpiece to the jig 51 W becomes difficult without much change in gripper strength compared to

[0015] Also, since a thick leaf spring must be formed by bending many times, there is a problem that the manufacturing cost increases
