PURPOSE:To enable taking-out/returning of a material at random position by constructing to separate between each layer of material supported by vertically arranged supporting member such that the upper layer is lifted by longer distance. CONSTITUTION:Upon lifting of longitudinal shaft 3 through motor, pinion and rack (not shown), a projected member 4 is also lifted together. Then at the position of slit 20 in outer tube 19, the projected member 4 will project through the slit 20 and engage with a supporting member 2. Consequently, the longitudinal shaft 3 will lift together with the supporting member 2 to engage the rotary wheel 14 of supporting member 2 with the lower face of projected section 1h of material 1 to lift it 1. When setting the pitch of projected member 4 longer than that of supporting member 2 under lowered state, the supporting member 2 at upper position will start lifting first. With such arrangement, supply/delivery of material on random layer can be performed without causing interference between layers. |
