Plate material conveying device

Abstract

The present invention provides a plate material conveying device including a compact traveling member to enable an increase in plate material conveyance speed and a reduction in time required for acceleration and deceleration and to allow small plate materials to be more efficiently conveyed, the plate material conveying device further enabling one of a gripper and a suction type plate material holder to be selected for conveyance of a plate material. Traveling members 13, 14 are provided on respective tracks 11, 12 so as to travel freely along the respective tracks 11, 12. Each of the traveling members 13, 14 has a plate material holder support frame 21, 22 supporting suction type plate material holders 23A, 23B, 23C. The plate material holder support frame 21, 22 has a frame main body 21a, 22a, and a turning frame 21b, 22b which is turnable in a substantially horizontal direction with respect to the frame main body 21a, 22a and which is turnable to a position where the supported plate material planarly overlaps the adjacent track. Each of the turning frames 21b, 22b has a gripper 60 gripping an end of the plate material. An opening of the gripper is configured to face a central side of the plate material.
