PURPOSE:To increase the stroke with reduce the space of an interchange apparatus of pallet and the like mounting a work piece by constructing such that the movable table is reciprocated through a guide shaft while a link for stopping the pallet is rotated quickly through drive shaft and a planetary gear mechanism. CONSTITUTION:When the stopper pin 11 of second link 10 is stopped in the pass groove 6b of pallet 6 on a base 26 while first and second links 17, 10 are arranged in series and the pallet 6 is waiting motion, the movable table 25 is moved by an oil motor not shown through a wam 36, a warm wheel 35, a pinion 32 and a hook 27 while the drive shaft 19 is rotated through the gears 41, 42 and the second link 10 is moved through first link 17 thus to move the pallet together with the stopper pin 11. With such arrangement, the stroke can be increased to achieve smooth motion by setting the number of tooth of planetary gears 16, 23 properly. |
