该装置通过托盘仓两组气动装置协调动作，实现空托盘准确释放，通过链条和辊筒式输送机及时、准确、平稳地将空托盘送到码垛位置。托盘库可容10个以上托盘，当剩下空托盘不足时，系统发出要求补充托盘的信号直至自动停车,重托辊输送机（出垛机）前采用防撞钢板；托盘四周的挡板为可调节设计，适用于不同尺寸的托盘。

  Through the coordinated action of two sets of pneumatic devices in the pallet bin, the device realizes the accurate release of empty pallets, and delivers the empty pallets to the stacking position in a timely, accurate and stable manner through chains and roller conveyors. The pallet warehouse can accommodate more than 10 pallets. When the remaining empty pallets are insufficient, the system sends a signal to replenish pallets until it stops automatically. The heavy idler conveyor (stacker) uses anti-collision steel plates; the baffles around the pallets are optional. Adjustable design, suitable for trays of different sizes.
