[0036] In the present technical solution, the material box storage and retrieval unit 100 takes out the material box 510 from the material box storage position of the shelf 500 and hands it over to the transport unit 200; the transport unit 200 transports the material box 510 to the input-output unit 410 of the operating table 400; by docking the handover unit 300 at the input-output unit 410 of the operating table 400, the material box 510 carried on the transport unit 200 can be transferred to the input-output unit 410 through the handover unit 300, and after the operating table 400 operates the material box 510, the input-output unit 410 can hand over the material box 510 to the transport unit 200, and the transport unit 200 transports and hands it over to the material box storage and retrieval unit 100, and the material box storage and retrieval unit 100 then sends the material box 510 back to the original storage position of the shelf 500. The materials are put in and taken out of the warehouse through the cooperation of each operation unit. The handover unit 300 completes the handover of the material box 510 from the transport unit 200 to the operating table 400 and from the operating table 400 to the transport unit 200. The handover process of the material box 510 is stable and high-speed, which reduces the congestion of the transport unit 200 in the input and output unit of the operating table 400.

[0037] Specifically, Figures 4 to 6As shown, the transport unit 200 includes a mobile chassis 210, the mobile chassis 210 is provided with a bearing surface for carrying the material box 510, and the bearing surface is provided with a plurality of docking grooves 211; the bearing assembly 310 is a toothed fork, and the toothed fork includes a plurality of insert teeth 311. When the transport unit 200 and the bearing assembly 310 of the handover unit 300 are docked at the first position, the insert teeth 311 are inserted into the docking grooves 211. Figure 6 As shown, when the transport unit 200 is connected with the handover unit 300, the teeth 311 are gradually inserted into the docking groove 211 as the transport unit 200 moves, until the transport unit 200 moves to a specified position and stops, and the plurality of teeth 311 of the toothed fork are inserted into the plurality of docking grooves 211 of the mobile chassis 210. At this time, the toothed fork is located at the bottom of the material box 510. By controlling the lifting assembly to work, the toothed fork moves upward in the height direction to carry the material box 510 thereon, thereby separating the material box 510 from the transport unit 200, and realizing the handover of the material box 510 from the transport unit 200 to the handover unit 300.

[0038] Specifically, Figure 5 As shown, the bearing assembly 310 of the handover unit 300 is configured as a toothed fork composed of four teeth 311, and the teeth 311 include a driving wheel 3112 and a conveyor belt 3111, and the driving wheel 3112 drives the conveyor belt 3111 to move, and the conveyor belt 3111 is used to carry the material box 510 and drive the material box 510 to move. When the bearing assembly 310 of the handover unit 300 is docked with the input-output unit 410 in the second position, the conveyor belt 3111 drives the material box 510 to move to the input-output unit 410. In some embodiments, in order to enable the material box 510 to move smoothly along a preset direction on the bearing assembly 310, the driving wheels 3112 of the plurality of groups of toothings 311 are all driven by the same driving shaft and rotate at the same speed under the drive of the driving shaft, so that the movement speed of the conveyor belts 3111 of each toothing 311 is consistent, and then when the bearing assembly 310 of the handover unit 300 is docked with the input and output unit 410 of the operating table 400, the material box 510 can be stably handed over to the input and output unit 410. The lifting assembly includes a first motor 321 and a transmission mechanism, and the first motor 321 drives the bearing assembly 310 of the handover unit 300 to reciprocate up and down along the fixed guide rail in the height direction through the transmission mechanism, and the driving shaft is connected to the output shaft of the second motor 322 and rotates under the drive of the second motor 322.

[0039] like Figures 1 to 3As shown, the transport unit 200 further includes a track 220, and the track 220 is configured as a circular track 220. The mobile chassis 210 is disposed on the track 220 and can move along the track 220. The track 220 passes through the bottom of the shelf 500, the operating table 400 and the handover unit 300. When the mobile chassis 210 moves along the track 220 to the bottom of the shelf 500, the material box access unit 100 can dock with the mobile chassis 210 and complete the handover of the material box 510. The material box access unit 100 takes the material box 510 out of the material box storage position of the shelf 500 and carries it thereon. When the transport unit 200 moves to the bottom of the shelf 500 and docks with the material box 510 storage unit, the material box access unit 100 can place the material box 510 on the transport unit 200 and detach from the material box 510, and then the transport unit 200 transports the material box 510 to the handover unit 300. Figure 3 As shown, in some further embodiments, the circular track 220 includes a straight section and a curved section, the straight section is located at the bottom of the shelf 500, the curved section is located at the bottom of the operating table 400, and the handover unit 300 is located at the end where the straight section is connected to the curved section.

[0040] In this embodiment, the input / output unit 410 includes an input unit for moving the material box 510 into the operating platform 400 and an output unit for moving the material box 510 out of the operating platform 400, respectively, and the handover unit 300 includes a first handover unit located at the input unit and a second handover unit located at the output unit. When the bearing assembly 310 of the first handover unit is docked with the input unit at the second position, the mobile chassis 210 of the transport unit 200 can move from the input unit of the input / output unit 410 to the output unit along the track 220 and hand over the material box 510 with the bearing assembly 310 of the second handover unit. That is, when the first handover unit lifts the material box 510 on the transport unit 200 upward and moves it to the second position, the transport unit 200 can move from the bottom of the toothed fork of the first handover unit along the track 220 to the bottom of the toothed fork of the second handover unit, and is ready to receive the material box 510 received from the output unit by the second handover unit.

[0041] In this embodiment, either end of the operating table 400 can be set as an input unit or an output unit, and the conveying direction of the material box 510 of the input and output unit 410 can be switched. The first handover unit and the second handover unit are respectively arranged at both ends of the input and output unit 410. One of the first handover unit and the second handover unit is used to transport the material box 510 carried on the transport unit 200 to the input unit of the input and output unit 410, and the other is used to transport the material box 510 sent out by the output unit of the input and output unit 410 to the transport unit 200. When in use, the transport unit 200 includes a plurality of mobile chassis 210 that move in a circle on the circular track 220. The process in which the handover unit 300 is used to receive the material box 510 from the output unit of the input / output unit 410 and hand it over to the transport unit 200 includes: the handover unit 300 first moves to the second position and docks with the output unit of the input / output unit 410, the empty transport unit 200 (not carrying the material box 510) moves to a specified position below the handover unit 300, and the docking of the handover unit 300 with the transport line means that the bearing surface of the input / output unit 410 that carries and transports the material box 510 is at the same height as the bearing surface of the material box 510 of the bearing component 310 of the handover unit 300, and the material box 510 can be moved from one of the two to the other; the material box 510 moves from the input / output unit 410 to the conveyor belt 3111 under the drive of the input / output unit 410 and the conveyor belt 3111; then the lifting component of the handover unit 300 works to control the bearing component 310 to move in the height direction and from When the load-bearing assembly 310 is moved from the second position to the first position, the load-bearing assembly 310 of the connection unit 300 is docked with the transport unit 200 which has been moved to the bottom of the load-bearing assembly 310 in advance, and the toothed fork 311 of the connection unit 300 is inserted from top to bottom into the docking groove 211 of the mobile chassis 210. When the height of the upper surface of the conveyor belt 3111 of the toothed fork 311 is lower than the load-bearing surface of the mobile chassis 210, the material box 510 is transferred from the toothed fork of the connection unit 300 to the mobile chassis 210 of the transport unit 200, and then the mobile chassis 210 is controlled to move forward along the track 220, so that the docking groove 211 of the mobile chassis 210 is disengaged from the toothed fork 311 of the connection unit 300 in the horizontal direction. After the toothed fork 311 and the mobile chassis 210 are completely disengaged, the load-bearing assembly 310 is controlled by the lifting assembly to move from the first position to the second position to prepare for receiving the next material box 510. As an example, the input and output unit 410 is configured as a conveyor line, which transports the material box 510 along a preset direction, and the conveyor line transports the material box 510 from the input unit to the output unit along the transport direction.

[0042] The process of the handover unit 300 for receiving the material box 510 from the transport unit 200 and handing it over to the output unit of the input and output unit 410 includes: first, the bearing assembly 310 of the handover unit 300 moves to the first position, the transport unit 200 moves to the first position along the track 220 and docks with the handover unit 300, during the movement of the transport unit 200, the inserting teeth 311 of the toothed fork are gradually inserted into the docking groove 211 of the mobile chassis 210 in the horizontal direction, the transport unit 200 stops after moving to the specified position, the inserting teeth 311 are located in the docking groove 211 and at the bottom of the material box 510, and the lifting assembly of the handover unit 300 drives the bearing assembly 310 to move upward in the height direction, so that The toothed fork lifts the material box 510 from the bottom of the material box 510 and disengages from the mobile chassis 210 of the transport unit 200. When the bearing assembly 310 of the handover unit 300 moves to the second position in the height direction, the transport unit 200 mechanically moves along the track 220 to the other end of the operating table 400. The conveyor belt 3111 of the toothed 311 starts to move under the action of the driving wheel 3112, and moves the material box 510 on the conveyor belt 3111 to the input and output unit 410. After the material box 510 is completely disengaged from the conveyor belt 3111, the bearing assembly 310 of the handover unit 300 moves downward to the first position again and waits until the next mobile chassis 210 carrying the material box 510 moves to the designated position.

[0043] In this embodiment, the first handover assembly and the second handover assembly are used to complete the handover of the material box 510 from the transport unit 200 to the operating table 400 and from the operating table 400 to the transport unit 200. The handover process of the material box 510 is stable and high-speed, which reduces the congestion of the transport unit 200 in the input and output unit of the operating table 400. The handover unit 300 of this embodiment can be fixed to the ground and carry and move the material box 510 in a lifting manner, so that the movement process of the material box 510 is more stable and fast.

[0044] Specifically, Figure 7 , 8 As shown, the material box access unit 100 includes an actuator 110, a column 120 and a horizontal guide rail 120, the actuator 110 is used to carry the material box 510, the column 120 is slidably connected to the horizontal guide rail 120 and can move in the horizontal direction along the horizontal guide rail 120, the actuator 110 is slidably connected to the column 120 and can move in the vertical direction along the column 120, and the horizontal guide rail 120 is fixedly connected to the shelf 500. Through the cooperation of the actuator 110, the column 120 and the horizontal guide rail 120, the actuator 110 can move in the horizontal direction and in the vertical direction, and can move in a plane parallel to the pick-and-place plane of the shelf 500, so as to store and retrieve the material box 510 in any storage position of the shelf 500.

[0045] like Figure 7 , 8 As shown, the execution component 110 includes a pallet 1101 and a robot 1102. The pallet 1101 is used to carry the material box 510. The robot 1102 is used to move the material box 510 into or out of the pallet 1101. The robot 1102 includes a first robot arm and a second robot arm located on both sides of the pallet 1101. The robot 1102 is configured as a telescopic arm capable of performing telescopic movement. Blocking members 1103 are rotatably connected at both ends of the robot 1102. The blocking member 1103 can form a block when rotating relative to the robot 1102. Figure 7 The first state and Figure 8 When the blocking member 1103 forms the first state relative to the robot arm 1102, the first robot arm and the second robot arm can move relative to the material box 510 along both sides of the material box 510, and when the blocking member 1103 forms the second state relative to the robot arm 1102, the blocking sheet can abut against the material box 510, and the first robot arm and the second robot arm can drive the material box 510 to move.

[0046] In this embodiment, first, the blocking member 1103 forms a first state relative to the robot arm 1102, and the blocking member 1103 can avoid the material box 510 during the telescopic movement of the robot arm 1102. The robot arm 1102 extends from both sides of the material box 510 into the shelf 500 or the transport unit 200 through the telescopic movement, so that the material box 510 is completely between the two robot arms 1102 (such as Figure 8 ), and then control the blocking member 1103 to rotate along the fixed axis, so that the blocking member 1103 abuts against the material box 510 and applies a force to the material box 510 during the telescopic movement of the robot arm 1102, so that the material box 510 moves with the robot arm 1102, that is, the transportation of the material box 510 is realized. Through the structure of this embodiment, by controlling the direction of the telescopic movement, the material box 510 can be moved from the shelf 500 or the transport unit 200 to the pallet 1101, and the material box 510 can be moved from the pallet 1101 to the storage position of the shelf 500 or the mobile chassis 210 of the transport unit 200.
