A channel is reserved between the space-time material tray 9 and the material tray 9 filled with the materials 11 at the uppermost layer. The main control machine 61 starts the second driving member 33, the second driving member 33 drives the supporting plate 34 to pass through the channel, and the initial height of the pull-back block 37 is higher than the supporting plate 34 and higher than the bottom of the empty tray 9, so that in the process that the supporting plate 34 drives the pull-back block 37 to move, the empty tray 9 applies pressure to one side of the pull-back block 37, so that the elastic member 38 compresses. When the pullback block 37 moves to the outside of the empty tray 9, the empty tray 9 no longer applies force to the pullback block 37, so that the pullback block 37 returns to the original position upwards under the elastic force of the elastic member 38, and the surface of the pullback block 37 is higher than the bottom of the tray 9 on the receiving plate 57. Then the main control computer 61 starts the first driving member 32, and the first driving member 32 drives the receiving plate 57 to return to the original position, so that the material tray 9 is no longer received. The empty tray 9 will fall under its own weight onto the support plate 34. In order to ensure that the supporting plate 34 falls in place, the lower pressing plate 31 is arranged to assist in pressing down, the main control machine 61 starts the lower pressing air cylinder 30, the lower pressing air cylinder 30 drives the lower pressing plate 31 to move downwards, and the lower pressing plate 31 presses down the empty material tray 9 until the empty material tray 9 is located on the supporting plate 34. Then the main control computer 61 starts the second driving part 33, the second driving part 33 drives the supporting plate 34 and the pull-back block 37 to move back, the pull-back block 37 drives the tray 9 above the pull-back block to move together with the supporting plate 34 until the supporting plate 34 moves to the opening 46, the in-place sensor 58 senses the position of the supporting plate 34, when the supporting plate 34 is sensed, a signal is sent to the main control computer 61, and the main control computer 61 closes the second driving part 33. Then the fifth driving member 43 drives the lifting pallet 41 to move upward, and the initial height of the lifting pallet 41 does not exceed the height of the supporting plate 34. The jacking supporting plate 41 can jack up the empty tray 9 on the supporting plate 34 in the upward movement process, in the upward movement process of the empty tray 9, the two sides of the empty tray 9 can apply upward force to the inclined surface 53 of the receiving block 48, so that the receiving block 48 rotates, the back of the receiving block 48 applies pressure to the spring pin 49 to compress the spring pin, and the empty tray 9 can pass through smoothly after the receiving block 48 rotates. The empty tray 9 can not generate upward force to the bearing block 48 any more, the bearing block 48 is restored to the original position under the elastic force of the spring pin 49, and the top of the bearing block 48 supports the empty tray 9 through the notch 60. The four corners of the empty tray 9 are limited by the second rack 39. And then the main control machine 61 controls the fifth driving element 43 to move reversely, and the fifth driving element 43 drives the jacking supporting plate 41 to move downwards to the original position.

In the above process, after the tray 9 is jacked up by the jacking plate 41, the second driving member 33 drives the supporting plate 34 to return to the original position. After the empty material tray 9 is transferred by the supporting plate 34, the servo motor is started, the servo motor drives the vertical block 28 and the bearing frame 22 to move upwards through the first synchronizing wheel, the second synchronizing wheel and the ball screw 25 until the material tray 9 on the uppermost layer is abutted against the in-place limiting plate 29, and then the next batch of materials 11 are grabbed.

When the full material sensing switch 44 on the second material rack 39 senses the empty material tray 9 on the uppermost layer, a signal is sent to the main control computer 61, and the main control computer 61 gives an alarm to remind a worker to take the empty material tray 9 away.
