Both the first lifting pusher 32 and the second lifting pusher 33 consist of a pusher frame, a motor, a pulley, a cylinder, and a conveyor belt (the pusher frame, motor, cylinder, and conveyor belt are all existing technologies; the cylinder is used for lifting, and the motor, pulley, and conveyor belt are used for conveying). Lifting and conveying blocks 34 are installed inside the conveying roller 31. Two lifting and conveying blocks 34 are provided. The lifting and conveying blocks 34 are installed inside the conveying roller 31 by cylinders and are lifted and lowered within the conveying roller 31 under the action of the cylinders (the cylinders are existing technologies and are not shown in the figure, so they are not described in detail). (Details omitted) The feeding roller 11 and the discharging roller 21 are respectively located at both ends of the conveying roller 31. The unpacking robot 4 is located between the feeding conveyor line 1 and the discharging conveyor line 2. The unpacking robot 4 and the positioning fixture 7 are respectively located on both sides of the roller conveyor line 3. The unpacking robot 4 includes a fixed frame 41. The top of the fixed frame 41 is fixedly connected to the unpacking manipulator 42. The free end of the unpacking manipulator 42 is rotatably connected to the unpacking frame 43. The unpacking frame 43 is fixedly connected to the first vacuum suction cup 44. The unpacking frame 43 is fixedly connected to the slide rail 45. The slide rail 45 is equipped with an adjusting cylinder 46. The adjusting cylinder 46 is fixedly connected to the second vacuum suction cup 47. The handling robot 6 is located on the side of the positioning fixture 7 away from the roller conveyor line 3. The handling robot 6 includes... The system includes a support frame 61, a handling robot 62 fixedly connected to the top of the support frame 61, a handling frame 63 rotatably connected to the free end of the handling robot 62, a third vacuum suction cup 64 fixedly connected to the handling frame 63, storage racks 5 arranged on both sides of the handling robot 6, a turnover cart 8 located inside the storage rack 5, the storage rack 5 including a storage frame 51, a guide rail 52 fixedly connected inside the storage frame 51, a lifting cylinder 53 mounted on the guide rail 52, a lifting frame 54 fixedly connected to the lifting cylinder 53, and the turnover cart 8 located inside the storage frame 51.

[0022] In use, first place the flat cardboard box into the storage rack 5 using the turnover cart 8, ensuring the box is positioned on the lifting frame 54. Then, activate the lifting cylinder 53, causing it to slide upwards along the outer surface of the guide rail 52, lifting the box upwards on the lifting frame 54. Once the box reaches the specified height, the handling robot 6 moves onto the storage rack 5 and then slowly moves downwards. The third vacuum suction cup 64 then grips the box and creates negative pressure, allowing the handling robot 6 to move the box onto the push plate 73. At this point, the third vacuum suction cup... 64. The internal air pressure is restored, and the cardboard box is lowered. At this time, the positioning cylinder 74 pushes the cardboard box to the designated position through the positioning plate 75, and then the positioning cylinder 74 retracts. Then, the pushing cylinder 72 pushes the cardboard box to the designated position through the pushing plate 73. When the cardboard box has reached the designated position, the unpacking robot 4 moves the unpacking frame 43 into the cardboard box and sucks the cardboard box with the first vacuum suction cup 44 and the second vacuum suction cup 47. Then, the adjusting cylinder 46 opens the cardboard box, and then moves it above the refrigerator to wait for the box to be repacked. Cardboard boxes in the storage rack 5 are replenished manually after they are used up.

[0023] During this process, refrigerators are conveyed via the feeding conveyor line 1. When a refrigerator enters the feeding conveyor line 1 and reaches the position of the first lifting feeding barrier 12, if there is a refrigerator at the second lifting feeding barrier 12, the first lifting feeding barrier 12 rises to block the refrigerator. If there is no refrigerator at the position of the second lifting feeding barrier 12, the first lifting feeding barrier 12 does not rise, and the feeding conveyor line 1 conveys the refrigerator to the position of the second lifting feeding barrier 12. The refrigerator continues to be conveyed to the top of the roller conveyor line 3. When there is no refrigerator on the first lifting pusher 32, the first lifting pusher... When machine 32 rises, the refrigerator moves onto the first lifting pusher 32. If there is a refrigerator on the first lifting pusher 32, the first lifting pusher 32 descends, and the second lifting feed barrier 12 rises to block the refrigerator. The conveying roller 31 transports the refrigerator forward to the first lifting conveying barrier 34. When the refrigerator reaches the first lifting conveying barrier 34, if there is a refrigerator on the second lifting conveying barrier 34, the first lifting conveying barrier 34 rises to block the refrigerator. If there is no refrigerator on the second lifting conveying barrier 34, the conveying roller 31 sends the refrigerator to the second lifting feeder 34. Lowering conveyor block 34; when the refrigerator reaches the second lifting conveyor block 34, the second lifting conveyor block 34 rises first to block the refrigerator, and the unpacking robot 4 places the opened carton on the refrigerator; after the unpacking robot 4 has placed the carton, the unpacking robot 4 resets, and the conveyor roller 31 conveys the refrigerator with the carton placed on it to the second lifting pusher 33. When there is a refrigerator on the second lifting pusher 33, the second lifting pusher 33 rises first and then conveys the refrigerator forward to the first lifting discharge block 22 of the discharge roller 21; when the refrigerator is conveyed to the first lifting discharge block 22, the second lifting pusher 33 rises first to block the refrigerator, and then conveys the refrigerator forward to the first lifting discharge block 22 of the discharge roller 21. When the lowering discharge barrier 22 is in position, and there is a refrigerator at the second lifting discharge barrier 22 position, the first lifting discharge barrier 22 rises up to block the refrigerator. When there is no refrigerator at the second lifting discharge barrier 22 position, the discharge roller 21 transports the refrigerator to the second lifting discharge barrier 22 position. When the refrigerator reaches the second lifting discharge barrier 22 position, and there is a refrigerator on the connected refrigerator conveyor line, the second lifting discharge barrier 22 rises up to block the refrigerator. When there is no refrigerator on the connected refrigerator conveyor line, the discharge roller 21 transports the refrigerator to the connected refrigerator conveyor line.
