Abstract
A tray holding device includes a frame (20) that defines a tray elevation area (A) in which a tray containing workpieces can be lifted and lowered and that allows the loading and unloading of workpieces from above, a lower supporting member (40) that is fixed to the frame to horizontally receive and support the tray in the tray elevation area (A), an elevation mechanism (60) that is provided at the frame to lift and lower the tray supported by the lower supporting member, and an upper supporting mechanism (50) that is mounted to the frame to receive and support the tray lifted by the elevation mechanism from below and to horizontally carry it out. Thus, the size, installation space, etc., of the tray holding device can be reduced, and the productivity can be heightened by shortening a waiting time.
