When the tableware on the main conveying belt is classified and enters the sorting conveyor belt 83 of the first boxing mechanism 8, the sorting conveyor belt 83 transfers and transports the tableware. The motor of the blocking device 87 drives the blocking plate to shrink, and the first sorting box 85 falls onto the carton conveyor belt 81. The first conveying motor 84 drives the carton conveyor belt 81 to transport the first sorting box 85 to the designated position. When the arrival detection device 94 detects that the first sorting box 85 has arrived at the designated position, the first conveying motor 84 stops working. The second conveying motor 89 continues to drive the sorting conveyor belt 83 to transport the sorted tableware. When the tableware passes through the second counting device 93, it will be counted and the quantity will be allocated according to the capacity of the first sorting box 85 and the size of the tableware.

The first sorting box 85 falls on the blocking plate of the blocking device 87, preparing for the next box drop. Repeat the above actions to pack and transport the tableware on the sorting conveyor belt 83. As the main conveyor belt keeps transporting, tableware of different sizes automatically falls into the corresponding discharge ports. The tableware falling into the first discharge port 14, the second discharge port 15 and the third discharge port 16 are respectively packed by the first packing mechanism 8, the second packing mechanism 9 and the third packing mechanism 10, thereby realizing equipment automation, reducing labor, reducing contact pollution, and high work efficiency.

[0029] like Figure 5As shown, the fourth packing mechanism 11 includes a conveying part 111, and a box sending part 112 is opened on the top of the fourth packing mechanism 11. When the tableware on the main conveyor belt is transported to the fourth discharge port 17 through the first conveyor belt 4, the second conveyor belt 5, the third conveyor belt 6 and the fourth conveyor belt 7, the first counting device 12 counts the number of tableware, and calculates the number of tableware that the fourth sorting box can accommodate according to the system. When the tableware transported reaches a predetermined number, the main conveyor belt stops conveying, and the tableware falls into the fourth sorting box through the fourth discharge port 17. After the fourth sorting box is full, the conveying part 111 is started to transport the full fourth sorting box out, and at the same time, the box sending part 112 sends another fourth sorting box to the conveying part 111 and transports it to the bottom of the fourth discharge port 17. The conveying part 111 stops, and the conveyor belt motor 2 is started to drive the main conveyor belt to transport the tableware again until all the tableware on the main conveyor belt is packed.

[0030] The specific implementation method is as follows: the conveyor belt motor 2 and the running motor 3 are started, and the conveyor belt motor 2 drives the main conveyor belt to drive. The washed tableware moves to the first conveyor belt 4 via the dinner plate car, and tableware of different sizes is transported forward via the first conveyor belt 4. When passing through the first discharge port 14, the tableware with the smallest volume falls into the first discharge port 14 and is boxed by the first packing mechanism 8. The remaining tableware continues to be transported forward via the second conveyor belt 5. When passing through the second discharge port 15, the remaining tableware with the smallest volume falls into the second discharge port 15 and is boxed by the second boxing mechanism 9. The remaining tableware continues to be transported forward via the third conveyor belt 6. When passing through the third discharge port 16, the remaining tableware with the smallest volume falls into the third discharge port 16 and is boxed by the third boxing mechanism 10. The remaining tableware is transported forward via the fourth conveyor belt 7 and finally falls into the fourth discharge port 17 and is boxed by the fourth boxing mechanism 11. The working principles of the first boxing mechanism 8, the second boxing mechanism 9 and the third boxing mechanism 10 are the same.

[0031] Taking the first packing mechanism 8 packing tableware as an example, when the tableware falls onto the first packing mechanism 8, the first conveying motor 84 is started to drive the carton conveyor belt 81, and the second conveying motor 89 is started to drive the sorting conveyor belt 83 to transmit. When the tableware on the main conveyor belt is classified and enters the sorting conveyor belt 83 of the first packing mechanism 8, the sorting conveyor belt 83 transfers and transports the tableware, the motor of the blocking device 87 drives the blocking plate to shrink, and the first sorting box 85 falls onto the carton conveyor belt 81. The first conveying motor 84 drives the carton conveyor belt 81 to transport the first sorting box 85 to the designated position. When the arrival detection device 94 detects that the first sorting box 85 has reached the designated position, the first conveying motor 84 stops working, and the second conveying motor 89 continues to drive the sorting conveyor belt 83 to transport the sorted tableware. When the tableware passes through the second counting device 93, it will be counted and the quantity will be allocated according to the capacity of the first sorting box 85 and the size of the tableware. The movable arm device 91 is transferred to the top of the first sorting box 85 by the swing device 90, and the tableware is clamped by the movable arm device 91 and placed in the first sorting box 85. When the second counting device 93 counts the number of tableware to be allocated, the swing device 90 stops working. 0 and the movable arm device 91 stop working, the first conveying motor 84 restarts to drive the carton conveyor belt 81 to convey, and the first sorting box 85 filled with tableware is sent out of the warehouse. At this time, the blocking device 87 shrinks, and the first sorting box 85 falls onto the carton conveyor belt 81. As the carton conveyor belt 81 moves to the in-place detection device 94, the first conveying motor 84 stops, and the blocking device 87 resets to support and block the first sorting box 85 falling from above. The upper and lower devices 88 transport the upper first sorting box 85 to the shrinking device 86, and the motor of the shrinking device 86 is started to block its blocking plate The first sorting box 85 shrinks and disengages, and the first sorting box 85 falls on the blocking plate of the blocking device 87 to prepare for the next box drop. The above actions are repeated to pack and transport the tableware on the sorting conveyor belt 83. As the main conveyor belt keeps transporting, tableware of different sizes automatically falls into the corresponding unloading ports. The tableware falling into the first unloading port 14, the second unloading port 15 and the third unloading port 16 are respectively packed by the first packing mechanism 8, the second packing mechanism 9 and the third packing mechanism 10, thereby realizing equipment automation, reducing labor, reducing contact pollution, and high work efficiency.

[0032] The number of tableware transported by the fourth conveyor belt 7 is counted by the first counting device 12, and the number of tableware that the fourth sorting box can accommodate is calculated according to the system. When the number of tableware transported reaches a predetermined number, the main conveyor belt stops conveying, and the tableware falls into the fourth sorting box through the fourth discharge port 17. After the fourth sorting box is full, the conveying unit 111 is started to transport the full fourth sorting box out, and at the same time, the box delivery unit 112 delivers another fourth sorting box to the conveying unit 111 and transports it to the bottom of the fourth discharge port 17. The conveying unit 111 stops, and the conveyor belt motor 2 is started to drive the main conveyor belt to transport the tableware again until all the tableware on the main conveyor belt is packed.
