PURPOSE:To prevent the generation of dust due to friction between a claw and a tray by operating a claw with a protrusion vertically without rubbing it against a tray by means of one drive device alone through the cam mechanism employing two cam rollers and a claw with a protrusion. CONSTITUTION:This piling device is provided with a claw 1' where a protrusion 17 is attached and a forcing means which keeps a claw opening roller 7, a claw returning roller 8 and the claw 1' in an open or close condition. In addition, there is a cam mechanism which opens while the claw 1' goes down and returns to its original position at its lower limit. Therefore, when the claw 1' has gone down and piled up a tray 14' on a lower tray 15', the claw 1' opens and comes to its lower limit without rubbing against the tray 15'. At this time, the claw 1' returns to its original position and is inserted into the piling portion of the tray 15'. As the result, one driving performs piling work without the claw 1' rubbing against the tray 15'. |
