[0030] The first pushing member 2 can comprise a first pushing plate 21 and a first linear driving structure 22 used to drive the first pushing plate 21 to move linearly, the bottom end of the first pushing plate 21 has a height not lower than the height of the top end of the conveying belt 11; the first linear driving structure 22 is used to drive the first pushing plate 21 to move above the conveying belt 11 from a first initial position, so that the first pushing plate 21 pushes the carton box 6 onto the adapter member 3, and the first linear driving structure 22 is used to drive the first pushing plate 21 to move to the first initial position when the first pushing plate 21 moves a first preset distance towards the adapter member 3.
[0031] Specifically, the first push plate 21 is vertically arranged, and the movement direction of the first push plate 21 pushed by the first linear driving structure 22 is perpendicular to the axis of the conveying belt 11. When the carton 6 is conveyed to the target position on the first conveying part which matches the first push plate 21, the first linear driving structure 22 pushes the first push plate 21 to move towards the conveying belt 11, and the first push plate 21 moves to the top of the conveying belt 11, so that the first push plate 21 pushes the carton 6 off the conveying belt 11 and onto the transfer piece 3; when the first push plate 21 moves a first preset distance towards the transfer piece 3, the first push plate 21 pushes the carton 6 onto the transfer piece 3, and then the first linear driving structure 22 drives the first push plate 21 to move to the first initial position, so as not to affect the conveying belt 11 conveying the subsequent carton 6 to the target position.

The second push plate 41 moves above the first receiving plate 31, so that the second push plate 41 pushes the fourth side of the carton 6. The second push plate 41 pushes the carton 6 to the receiving member 5. When the second push plate 41 moves a second preset distance towards the receiving member 5, the second push plate 41 pushes the carton 6 on the first receiving plate 31 to the receiving member 5. At this time, the third linear driving structure 42 drives the second push plate 41 to move to the third initial position, so as to avoid affecting the movement of the subsequent carton 6 to the first receiving plate 31. The third linear driving structure 42 can be one of a pneumatic cylinder, an electric cylinder, a hydraulic cylinder and a ball screw.
[0038] The receiving member 5 can include a second receiving plate 51 for receiving the carton 6 pushed out from the first receiving plate 31, and two fourth stop plates 52 arranged on both sides of the second receiving plate 51 for stopping the first side and the second side of the carton 6, respectively.
[0039] Specifically, the second receiving plate 51 is horizontally arranged, and an axis of the second receiving plate 51 is perpendicular to an axis of the first receiving plate 31 and a moving direction of the first receiving plate 31. The fourth stop plate 52 is perpendicular to the second receiving plate 51.
[0040] The plurality of receiving members 5 can be equidistantly arranged.

The first detection structure can be a first pressure sensor arranged at the target position of the conveying belt 11. The second detection structure can be a second pressure sensor arranged on the first receiving plate 31. The third detection structure can be a third pressure sensor arranged on the second receiving plate 51. When the first pressure sensor detects a first pressure value when the carton 6 moves to the target position of the conveying belt 11, the control member controls the first linear driving structure 22 to drive the first push plate 21 to move a first preset distance, so that the carton 6 is pushed to the first receiving plate 31. The second pressure sensor detects a second pressure value. The detection values of the third pressure sensors of each receiving member 5 are detected. If the third pressure sensor detects a third pressure value, it indicates that the receiving member 5 has the carton 6. Then, other receiving members 5 are selected as target receiving members 5. Since the distance between the initial positions of the second receiving plate 51 and the first receiving plate 31 of each receiving member 5 is determined, the control member controls the second linear driving structure 32 to drive the first receiving plate 31 to move a distance to a first distribution position. Then, the control member controls the third linear driving structure 42 to drive the second push plate 41 to move a second preset distance, so that the second push plate 41 pushes the carton 6 to the second receiving plate 51 of the receiving member 5.
