then the piston C11 is controlled, the piston rod C14 extends out of the piston C11 again to the maximum stroke position, and a pallet 4 is put into the pallet discharging hopper 31 again, so that the pallet 4 falls down onto the track 3 along the pallet discharging hopper 31 and the pallet discharging barrel 29, and the push-pull block 10 for feeding the pallet 4 is just clamped into the push-pull groove 33 arranged at the bottom of the pallet 4;
when the piston rod a13 moves upwards to the maximum stroke, the supporting plate 4 does not block the photoelectric sensor a41, so that the photoelectric sensor a41 can normally receive an optical signal;
when the photoelectric sensor A41 and the photoelectric sensor B17 can receive optical signals, the piston rod B39 of the piston B9 drives the supporting rod 6 to extend out of the piston B9 to the maximum stroke position, so that the supporting rod 6 forms a circular ring with the inner diameter smaller than the side length of the tray;
then starting the feeding conveyor belt 19, and sequentially placing trays on the feeding conveyor belt 19;
after a tray on the feeding conveyor belt 19 falls into the feeding cylinder 2 from the feeding conveyor belt 19, the material blocking rod 42 extends to block the tray on the feeding conveyor belt 19;
the trays falling from the feed conveyor 19 are blocked by the ring formed by the support rods 6; at this time, if the optical signal of the photoelectric sensor B17 is blocked by the tray on the supporting rod 6, the driving motor 23 drives the correction ring 8 to rotate, so as to drive the supporting rod 6 and the tray on the supporting rod 6 to rotate until the tray does not block the optical signal of the photoelectric sensor B17 any more;
the piston rod B39 of the piston B9 then retracts the piston B9 so that the carrier bar 6 is outside the feed cylinder 2, thereby dropping the pallet down onto the pallet 4;
the tray dropped onto the supporting plate 4 shields the optical signal of the photoelectric sensor A41, and then the piston rod A13 of the piston A5 drives the supporting plate 4 and the tray on the supporting plate 4 to move downwards until the tray just does not shield the optical signal of the photoelectric sensor A41 any more; at the moment, the piston rod B39 of the piston B9 drives the supporting rod 6 to extend out of the piston B9 to the maximum stroke position again, so that the supporting rod 6 forms a circular ring with the inner diameter smaller than the side length of the tray; the material blocking rod 42 retracts to enable the tray on the feeding conveyor belt 19 to continue to convey forwards;
repeating the steps until the number of the trays on the supporting plate 4 reaches the stacking requirement; then the material blocking rod 42 extends to block the tray on the feeding conveyor belt 19; in addition, the piston rod A13 of the piston A5 continues to move downwards, so that the bottom of the supporting plate 4 is contacted with the track 3, and the piston rod A13 continues to move downwards until the piston rod A13 retreats to the piston A5 to the maximum stroke;
