Abstract
A parts tray conveying system includes a first station for supplying a plurality of occupied trays each containing parts under a stacked condition; a second station for separating the occupied trays under the stacked condition one by one from the upper stage; and a third station for conveying the occupied trays. Also provided is a device for taking an upper-most one of the occupied trays under the stacked condition from the second station to the third station; a fourth station for discharging a plurality of empty trays each containing no parts one by one from the third station; and a fifth station for stacking the empty trays discharged by the fourth station. Accordingly, a large number of the parts trays can be compactly set under the stacked condition in the conveying system to thereby effectively utilize space in the conveying system.
