Description

Technical Field

[0001] This invention belongs to the field of material handling equipment technology, and particularly relates to AGV material handling equipment and its control method. Background Technology

[0002] Handling vehicles are logistics handling equipment used to move goods. Small products are numerous and varied. Currently, they are sorted manually and then transferred by forklifts, which is labor-intensive, has a low safety factor, and is not conducive to the intelligent, automated, safe and environmentally friendly development of enterprises and industries.

[0003] Currently, the load-bearing plates at the bottom of existing handling devices are laid flat on the ground, which takes up a large area when not in use and poses a certain degree of danger, affecting the efficiency of the device during use.

[0004] Therefore, we propose an AGV material handling device and its control method to solve the above problems. Summary of the Invention

[0005] This invention addresses the problem that existing handling devices in the prior art have load-bearing plates that are laid flat on the ground parallel to it. These plates occupy a large area when not in use, pose a certain degree of danger, and affect the efficiency of the device during operation. The invention proposes the following technical solution:

[0006] An AGV material handling device and its control method include a vehicle body, a power block, wheels, a limiting side plate, and a bearing base plate. The power block is installed on the right outer wall of the vehicle body. Wheels are installed at the bottom of both the vehicle body and the limiting side plate. The left side of the vehicle body is installed on the right outer wall of the limiting side plate. A receiving groove is opened on the left outer wall of the limiting side plate, and a bearing base plate is installed inside the receiving groove through a limiting mechanism. A roller is movably connected to the inside of a slot on the left outer wall of the bearing base plate. A connecting plate is fixedly installed at the bottom of the right outer wall of the bearing base plate, and the right side of the connecting plate is movably connected to the bottom of the left outer wall of the limiting side plate.

[0007] The limiting mechanism includes a limiting groove formed at the top of the inner wall of the receiving groove, and a return spring is welded to the middle of the inner wall of the limiting groove. The top of the inner side of the return spring is welded to the middle of the outer wall of the right side of the connecting side plate. The outer wall of the left side of the connecting side plate is installed on the outer wall of the right side of the U-shaped connecting block. A first limiting plate is fixedly installed at the bottom left side of the U-shaped connecting block, and a first abutting pad is intersected at the middle left side of the first limiting plate. A second limiting plate is fixedly installed at the upper left side of the U-shaped connecting block, and a plug-in block is fixedly installed at the bottom right side of the second limiting plate. The top right side of the plug-in block is inserted into the wedge-shaped groove formed at the top left side of the bearing base plate.

[0008] It can effectively store the load-bearing base plate when not in use, effectively solving the problem that traditional handling devices occupy a large area and are somewhat dangerous when in use, thus improving the working efficiency and safety of the device during use.

[0009] As a preferred embodiment of the above technical solution, the plug block is designed in the shape of a right trapezoid, and the wedge groove is designed to match the shape of the plug block.

[0010] The inclined shape of the plug block ensures that the operation of inserting the base plate into the receiving groove is not affected, thus improving the working efficiency of the device during use.

[0011] As a preferred embodiment of the above technical solution, multiple sets of first rolling balls are rolled and embedded in the outer walls of both the upper and lower ends of the connecting side plate, and the outer walls of the first rolling balls roll and abut against the inner wall of the sliding groove. The sliding groove is opened at both the upper and lower ends of the inner wall of the limiting groove.

[0012] With the combined action of the first rolling ball, the connecting side plate and the U-shaped connecting block can move relatively stably inside the limiting groove, improving the smoothness and efficiency of the device during use.

[0013] As a preferred embodiment of the above technical solution, multiple sets of limiting blocks are inserted at equal intervals in the middle of the outer wall on the left side of the U-shaped connecting block, and the top left end of the limiting block is fixedly installed on the inner wall of the limiting groove.

[0014] The special shape of the limiting block ensures that the U-shaped connecting block is positioned within the limiting groove when used on the base plate, thus limiting the position of the U-shaped connecting block.

[0015] As a preferred embodiment of the above technical solution, the upper end of the outer wall of the bottom end of the U-shaped connecting block rolls against the outer wall of the bottom end of the second ball, and the top end of the second ball rolls into the inner wall of the limiting groove.

[0016] The rolling action of the second ball further improves the stability efficiency of the U-shaped connecting block during its movement within the limiting groove.

[0017] As a preferred embodiment of the above technical solution, the bottom outer wall of the connecting plate abuts against the top of the second abutment pad, and the bottom of the second abutment pad is glued to the top left side of the abutment plate. The bottom right side of the abutment plate is fixedly installed on the top left side of the mounting plate, and the top right side of the mounting plate is fixedly installed on the bottom outer wall of the limiting side plate.

[0018] The second abutment pad and abutment plate limit the position of the unfolded connecting plate, effectively preventing excessive folding.

[0019] The control method for AGV material handling devices includes the following steps:

[0020] A: Initialization: System initialization can be performed at specific locations both indoors and outdoors;

[0021] B: Standby: After the handheld terminal sends the transfer task, whether the AGV can drive to the calling station in an unmanned state to stand by will be indicated by the terminal vibrating and making an audible reminder. The delivery personnel can confirm and cancel the reminder on the handheld terminal.

[0022] C: Transfer: The manual forklift places the materials on the flatbed trailer. After all the materials are loaded, the AGV confirms the completion through a handheld terminal and then travels to the target station in an unmanned state along the predetermined route.

[0023] After the AGV arrives at the receiving station, the terminal at the station will vibrate and make an audible alert. The operator can then confirm and cancel the alert using a handheld terminal.

[0024] D: Return to Position: Upon receiving the notification, the dispatcher arranges forklift drivers to unload the goods promptly. After unloading, the operator confirms completion via a handheld terminal, and the AGV continues to execute the next task. If there are no tasks, it will proceed to the standby station.

[0025] The beneficial effects of this invention are as follows:

[0026] With the help of the limiting mechanism, the load-bearing base plate can be effectively stored when not in use, which effectively solves the problem that traditional handling devices occupy a large area and are somewhat dangerous when in use, and improves the working efficiency and safety of the device during use.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention: it includes a vehicle body 1, a power block 2, a wheel 3, a limiting side plate 4, and a supporting base plate 22. The power block 2 is installed on the outer right side of the vehicle body 1. The wheel 3 is installed at the bottom of both the vehicle body 1 and the limiting side plate 4. The left side of the vehicle body 1 is installed on the outer right side of the limiting side plate 4. A receiving groove 5 is opened on the outer left side of the limiting side plate 4, and the supporting base plate 22 is installed inside the receiving groove 5 through a limiting mechanism. A roller 23 is movably connected to the slot hole opened on the outer left side of the supporting base plate 22. A connecting plate 21 is fixedly installed at the bottom of the outer right side of the supporting base plate 22, and the right side of the connecting plate 21 is movably connected to the bottom of the outer left side of the limiting side plate 4.

[0038] The limiting mechanism includes a limiting groove 6 opened at the top of the inner wall of the receiving groove 5, and a return spring 7 is welded to the middle of the inner wall of the limiting groove 6. The top of the inner side of the return spring 7 is welded to the middle of the outer wall of the right side of the connecting side plate 8. The outer wall of the left side of the connecting side plate 8 is installed on the outer wall of the right side of the U-shaped connecting block 11. A first limiting plate 14 is fixedly installed at the bottom left side of the U-shaped connecting block 11, and a first abutting pad 15 is intersected at the middle left side of the first limiting plate 14. A second limiting plate 16 is fixedly installed at the upper left side of the U-shaped connecting block 11, and a plug-in block 17 is fixedly installed at the bottom right side of the second limiting plate 16. The top right side of the plug-in block 17 is inserted into the wedge-shaped groove 24 opened at the top left side of the bearing base plate 22.

[0039] After the support base plate 22 is used, it is compressed into the inner side of the receiving groove 5 by the action of the movable connection on the right side of the connecting plate 21. After the top right side of the support base plate 22 abuts against the outer left side of the first abutting pad 15, the first limiting plate 14 and the U-shaped connecting block 11 are given a pushing force to the right. The pushing force, together with the elastic potential energy of the reset spring 7, drives the insertion block 17 to be inserted and locked into the wedge groove 24.

[0040] like Figure 3 and Figure 5 As shown, the plug-in block 17 is designed in the shape of a right trapezoid, and the wedge groove 24 is designed to match the shape of the plug-in block 17.

[0041] The inclined shape of the plug block 17 ensures that the operation of inserting the bearing base plate 22 into the inner side of the receiving groove 5 is not affected, thus improving the working efficiency of the device during use.

[0042] like Figure 3 and Figure 6 As shown, multiple sets of first rolling balls 9 are rolled and embedded in the outer walls of the upper and lower ends of the connecting side plate 8, and the outer walls of the first rolling balls 9 roll and abut against the inner wall of the slide groove 10. The slide groove 10 is opened at the upper and lower ends of the inner wall of the limiting groove 6.

[0043] With the combined action of the first rolling ball 9, the connecting side plate 8, along with the U-shaped connecting block 11, can move relatively stably inside the limiting groove 6, improving the smoothness and efficiency of the device during use.

[0044] like Figure 3 and Figure 6 As shown, multiple sets of limiting blocks 13 are inserted at equal intervals in the middle of the outer wall on the left side of the U-shaped connecting block 11, and the top left side of the limiting block 13 is fixedly installed on the inner wall of the limiting groove 6.

[0045] The special shape of the limiting block 13 ensures that the U-shaped connecting block 11 is positioned within the limiting groove 6 when the base plate 22 is used, thus limiting the position of the U-shaped connecting block 11.

[0046] like Figure 6 As shown, the upper end of the outer wall of the bottom of the U-shaped connecting block 11 rolls against the outer wall of the bottom of the second ball 12, and the top end of the second ball 12 rolls into the inner wall of the limiting groove 6.

[0047] The rolling action of the second ball 12 further improves the stability efficiency of the U-shaped connecting block 11 during its movement within the limiting groove 6.

[0048] like Figure 4As shown, the bottom outer wall of the connecting plate 21 abuts against the top of the second abutment pad 20, and the bottom of the second abutment pad 20 is glued to the top left side of the abutment plate 19. The bottom right side of the abutment plate 19 is fixedly installed on the top left side of the mounting plate 18, and the top right side of the mounting plate 18 is fixedly installed on the bottom outer wall of the limiting side plate 4.

[0049] The second abutment pad 20 and the abutment plate 19 limit the position of the unfolded connecting plate 21, effectively preventing excessive folding.

[0050] like Figure 7 The control method for the AGV material handling device shown includes the following steps:

[0051] A: Initialization: System initialization can be performed at specific locations both indoors and outdoors;

[0052] B: Standby: After the handheld terminal sends the transfer task, whether the AGV can drive to the calling station in an unmanned state to stand by will be indicated by the terminal vibrating and making an audible reminder. The delivery personnel can confirm and cancel the reminder on the handheld terminal.

[0053] C: Transfer: The manual forklift places the materials on the flatbed trailer. After all the materials are loaded, the AGV confirms the completion through a handheld terminal and then travels to the target station in an unmanned state along the predetermined route.

[0054] After the AGV arrives at the receiving station, the terminal at the station will vibrate and make an audible alert. The operator can then confirm and cancel the alert using a handheld terminal.

[0055] D: Return to Position: Upon receiving the notification, the dispatcher arranges forklift drivers to unload the goods promptly. After unloading, the operator confirms completion via a handheld terminal, and the AGV continues to execute the next task. If there are no tasks, it will proceed to the standby station.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
