ABSTRACT:
A conveyor system includes a number of closely spaced pallets (14) having nested pairs of ears (47,48 and 56,57) mounted on chain pins (33). First rollers (37) are mounted on pins (33) to ride between guide walls (38 and 39) and are engaged by a drive sprocket (12) to move the pallets through a number of work stations (16 to 19). Additional horizontal rollers (63, 71 and 72) are rotatably mounted on the pallets (14) to ride on one of the guide walls (30) and a third guide wall (74). A crowder pin device (81,82) is operated to engage a pallet at a work station to thrust the pallet rollers (37) against the wall (38) to fixedly position the pallet at the work station. Further precise positioning is attained by moving a tapered shot pin (84) into a hole (87) formed in the positioned pallet.
