Description

Technical Field

[0001] This utility model relates to the field of material changing devices, specifically an AGV automatic material changing device. Background Technology

[0002] In the previous production process, material changes were all done manually, including pulling, loading, and changing the materials. The used paper tubes also needed to be removed manually. This process was time-consuming and required a lot of manpower, necessitating a production line shutdown to wait for the process to complete. This resulted in a longer overall process time, reducing production line efficiency, and also hindered the allocation of production lines and personnel, leading to redundancy and chaos in personnel scheduling.

[0003] Document CN202222224097 discloses an unwinding device for easy material roll replacement. This unwinding device includes an unwinding mechanism and a material roll switching mechanism. The unwinding mechanism includes a material roll mounting component, two sets of transfer rollers, a first support base, and a conveyor component. The material roll mounting component is rotatably mounted on the first support base and drivably connected to the conveyor component. The material roll switching mechanism includes a second support base and at least one material application component. Each material application component includes a material application element, a conveyor shifting assembly, and at least one connecting element. The unwinding position is set on the moving trajectory of the material application element. The conveyor shifting assembly is mounted on the second support base. The connecting element is drivably connected to the conveyor shifting assembly. The material application element is connected to the connecting element, and the connecting element is configured to drive the material application element via the conveyor shifting assembly to apply material from a spare material roll to an old material roll. This structure has a complex material changing mechanism that is prone to damage when changing material rolls, and it requires manual material changing, resulting in low work efficiency.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this utility model discloses an AGV automatic material switching device, which optimizes the overall process, shortens the process time, increases overall production capacity, facilitates personnel arrangement and allocation, improves the overall production efficiency of the factory area, and increases profits.

[0006] The technical solution of this utility model is as follows: an AGV automatic material exchange device, including an AGV trolley located on one side of the frame and a gripper and clamping plate located on the frame. The clamping plate is provided inside the frame, and a transport structure is provided below the clamping plate. A material roll tray is provided between the transport structures. A paper tube storage component is also provided above the transport structure. A connecting gripper structure is provided on one side of the paper tube storage component. The clamping plate is connected to the frame through a guide rail.

[0007] By adopting the above technical solution, the material roll pallet is transported to the middle of the space by the AGV trolley, and then the material roll is clamped upward by the clamping plate. When the material roll is unloaded, only the waste paper tube is left. The connecting gripper picks up the waste paper tube between the clamping plates and places it on the paper tube storage component.

[0008] Preferably, the gripper structure includes a rotating structure and a gripper tightening structure. The rotating structure includes a cylinder and a rotating rod that are fixedly connected to the frame. The cylinder is located on both sides of the rotating rod. The output end of the cylinder is connected to one end of an L-shaped rotating plate. The end of the rotating plate is fastened to the rotating rod. The two ends of the rotating rod rotate through bearings and a base.

[0009] By adopting the above technical solution, the L-shaped rotating plate is driven by a cylinder. When the cylinder extends or retracts, the L-shaped rotating plate rotates around the rotating rod. That is, the L-shaped rotating plate drives the rotating rod to rotate, thereby driving the gripper to rotate. This allows the gripper to be controlled to rotate from between the clamping plates to the paper tube storage assembly.

[0010] Preferably, each side of the rotating rod is provided with a guide rail a, and a slider a is adapted on the guide rail a. The slider a is driven by a cylinder a to slide on the guide rail a. A slide plate is connected to the side of the slider a through a rotating plate. A slider b is provided at the outer end of the slide plate. The slider b is adapted to the guide rail b on the inner side of the base plate. A cylinder b is provided between the end of the inner side of the base plate away from the slide plate and the end of the slide plate away from the base plate.

[0011] By adopting the above technical solution, the distance between the grippers can be changed by the cylinder a driving the slider a to slide on the guide rail a, so as to facilitate clamping the waste paper tube. The slide plate is driven by the cylinder b, and the slide plate slides on the guide rail b on the base plate by the slider b, thereby changing the distance between the grippers and the waste paper tube, which facilitates gripping the grippers.

[0012] Preferably, the gripper tightening structure includes grippers and cylinder c. The grippers include a left gripper and a right gripper, which are completely symmetrical. The left gripper and the right gripper include L-shaped gripper bodies arranged in opposite directions. The ends of the gripper bodies are provided with inward arcs to facilitate gripping the waste paper tube.

[0013] By adopting the above technical solution, cylinder C controls the tightening and opening of the gripper by pulling the gripper to extend, thereby completing the gripper's gripping and releasing of the waste paper tube.

[0014] Preferably, the gripper body is connected to the base plate at the turning point via a rotating shaft, the end of the gripper body is connected to the connecting plate via rotating shaft a, the end of the connecting plate is rotatably connected to the base, the base is connected to the output end of cylinder c, and cylinder c is located on the outside of the base plate.

[0015] By adopting the above technical solution, the output end of cylinder c is connected to the base. When cylinder c pulls the base outward, the base drives the connecting plate, the connecting plate drives the end of the gripper body, and the gripper body turns and rotates around the rotating shaft to close inward. The gripper body is in a clamped state. When cylinder c pushes the base inward, the base drives the connecting plate, the connecting plate drives the end of the gripper body, and the gripper body turns and rotates around the rotating shaft to open outward. The gripper body is in an open state.

[0016] Preferably, the paper tube storage assembly is located on the side above the transport structure away from the clamping plate. The paper tube storage assembly includes brackets located on both sides of the transport structure. A support platform is provided inside the bracket. The support platform is inclined downward toward the side away from the clamping plate. A limiting plate is provided at the end of the support platform away from the clamping plate. The distance between the support platforms is adapted to the length of the waste paper tube.

[0017] By adopting the above technical solution, after the material roll is unloaded, the gripper clamps the waste paper tube and places it on the support platform. The limiting plate can block the waste paper tube and prevent it from falling down.

[0018] Preferably, the clamping plate clamps the material roll by an air-expanding brake sleeve. The clamping plate clamps the material roll by sliding the slider d on the guide rail d. The slider d is driven by an external cylinder. The guide rail d is located horizontally on the vertical plate. The vertical plate moves up and down on the vertical guide rail e by slider e, thereby causing the clamping plate to move up and down.

[0019] By adopting the above technical solution, when the clamping plate needs to clamp the material roll, the clamping plate is opened and placed on both sides of the material roll paper tube. Then the clamping plate closes the material roll, and the air-expansion brake sleeve is locked inside the material roll paper tube. The material roll rotates on the air-expansion brake sleeve to release the material.

[0020] Preferably, the transport structure includes a motor, a synchronous belt, and a drive shaft. The motor is located between the frames, and the motor output shaft drives the synchronous pulley to drive the synchronous belt. The inner side of the synchronous belt is provided with a guide rail parallel to the synchronous belt, and the guide rail is provided with a suitable carrier receiving frame for supporting the material roll. The side of the carrier receiving frame is connected to the synchronous belt through an L-shaped plate.

[0021] By adopting the above technical solution, when the motor drives the synchronous pulley and thus drives the synchronous belt for transmission, the L-shaped plate will then drive the carrier receiving frame to move on the guide rail, thereby transporting the material roll on the carrier receiving frame to the position below the clamping plate.

[0022] Preferably, the forks of the AGV trolley place the material roll pallet between the guide rails. The material roll pallet includes a support plate, legs at the bottom of the support plate, and support seats. Support seats are provided on both sides of the upper surface of the support plate, and the support seats are provided with downward arc-shaped material roll supports.

[0023] The spacing between the support bases is less than the length of the material roll, and the total height of the support legs, the support plate thickness, and the support base is lower than the height of the carrier receiving frame to the bottom.

[0024] By adopting the above technical solution, the material roll is placed between the guide rails through the material roll tray of the AGV trolley. Since the carrier receiving frame is higher than the support base, the material roll is placed on the carrier receiving frame. Then, it is transported to the underside of the clamping plate through the guide rails and the carrier receiving frame, so that the clamping plate can clamp and release the material.

[0025] The advantages of this utility model are as follows: 1. This utility model uses air, slider and guide rail to enable the gripper to extend and retract in any direction in the three-dimensional system, which makes it convenient for the gripper to transport the waste paper tube after feeding from between the clamping plates to the paper tube storage component, so as to complete the processing and collection of waste paper tubes. There is no need to manually replace it, which effectively improves the work efficiency of material replacement.

[0026] 2. This utility model connects the carrier receiving frame to the inside of the synchronous belt via an L-shaped plate. When the AGV trolley transports the material roll between the guide rails, the material roll is placed on the carrier receiving frame. Through the motor and synchronous belt, the material roll is automatically transported to the bottom of the clamping plate, where the clamping plate clamps it for feeding. This is simple, convenient and fast.

[0027] 3. This utility model optimizes the overall process, shortens the process time, increases the overall production capacity, facilitates the arrangement and allocation of personnel, improves the overall production efficiency of the factory area, and increases profits.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figure 1-4 As shown, the AGV automatic material transfer device includes an AGV trolley 8 located on one side of the frame 1 and grippers and clamping plates 7 located on the frame 1. The clamping plates 7 are located inside the frame 1, and a transport structure is located below the clamping plates 7. A material roll tray 9 is located between the transport structures. A paper tube storage assembly 11 is located above the transport structures. A transfer gripper structure is located on one side of the paper tube storage assembly 11. The clamping plates 7 are connected to the frame 1 via guide rails 701. The AGV trolley 8 transports the material roll tray 9 to the middle of the space. Then, the clamping plates 7 clamp the material roll 10 upwards. Material is fed onto the material roll 10. After the material roll 10 is fed, only waste paper tubes 12 are left. The transfer grippers pick up the waste paper tubes 12 between the clamping plates 7 and place them on the paper tube storage assembly 11.

[0035] The gripper structure includes a rotating structure and a gripper tightening structure. The rotating structure includes a cylinder 14 and a rotating rod 13 fixedly connected to the frame 1. The cylinder 14 is located on both sides of the rotating rod 13. The output end of the cylinder 14 is connected to one end of an L-shaped rotating plate 15. The end of the rotating plate 15 is fastened to the rotating rod 13. The two ends of the rotating rod 13 rotate through bearings and a base. The cylinder 14 drives the L-shaped rotating plate 15. When the cylinder 14 extends or retracts, the L-shaped rotating plate 15 rotates around the rotating rod 13. That is, the L-shaped rotating plate 15 drives the rotating rod 13 to rotate, thereby driving the gripper to rotate. The gripper can be controlled to rotate from between the clamping plates 7 to the paper tube storage assembly 11.

[0036] Each side of the rotating rod 13 is provided with a guide rail a16, and a slider a17 is adapted on the guide rail a16. The slider a17 is driven by a cylinder a18 to slide on the guide rail a16. The side of the slider a17 is connected to a slide plate 19 through a connecting plate 15. A slider b20 is provided at the outer end of the slide plate 19. The slider b20 is adapted to the guide rail b21 on the inner side of the base plate 22. A cylinder b20 is provided between the end of the inner side of the base plate 22 away from the slide plate 19 and the end of the slide plate 19 away from the base plate 22. The cylinder a18 drives the slider a17 to slide on the guide rail a16, which can change the distance between the grippers to facilitate clamping the waste paper tube 12. The cylinder b23 drives the slide plate 19, and the slide plate 19 slides on the guide rail b21 on the base plate 22 through the slider b20, thereby changing the distance between the grippers and the waste paper tube 12, which facilitates gripping the grippers.

[0037] The gripper tightening structure includes grippers and cylinder C24. The grippers include a left gripper and a right gripper, which are completely symmetrical. The left and right grippers include L-shaped gripper bodies 25 arranged in opposite directions. The ends of the gripper bodies 25 are provided with inward arcs to facilitate gripping the waste paper tube 12. The cylinder C24 controls the tightening and opening of the grippers by pulling the grippers to extend, thereby completing the gripping and releasing of the waste paper tube 12 by the grippers.

[0038] The gripper body 25 is connected to the base plate 22 via a pivot 26 at its turning point. The end of the gripper body 25 is connected to the connecting plate 27 via a pivot a. The end of the connecting plate 27 is rotatably connected to the base 28. The base 28 is connected to the output end of the cylinder c24. The cylinder c24 is located outside the base plate 22, and its output end is connected to the base 28. When the cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27, which in turn drives the end of the gripper body 25. The gripper body 25 turns around the pivot 26 and rotates inward to close, resulting in a clamped state. When the cylinder c pushes the base 28 inward, the base 28 drives the connecting plate 27, which in turn drives the end of the gripper body 25. The gripper body 25 turns around the pivot 26 and rotates outward to open, resulting in an open state.

[0039] The paper tube storage assembly 11 is located on the side above the transport structure away from the clamping plate 7. The paper tube storage assembly 11 includes brackets located on both sides of the transport structure. A support platform 1101 is provided inside the bracket. The support platform 1101 is inclined downward towards the side away from the clamping plate 7. A limiting plate 1102 is provided at the end of the support platform 1101 away from the clamping plate 7. The distance between the support platforms 1101 is adapted to the length of the waste paper tube 12. After the material roll 10 is unloaded, the gripper clamps the waste paper tube 12 and places it on the support platform 1101. The limiting plate 1102 can block the waste paper tube 12 to prevent it from falling down.

[0040] The clamping plate 7 clamps the material roll 10 via an air-expanding brake sleeve. The clamping plate 7 slides on the guide rail d31 via a slider d, thereby clamping the material roll 10. The slider d31 is driven by an external cylinder. The guide rail d31 is horizontally positioned on the vertical plate 32. The vertical plate 32 moves up and down on the vertical guide rail e34 via a slider e33, thereby causing the clamping plate 7 to move up and down. The slider e33 is also driven by the cylinder. When the clamping plate 7 needs to clamp the material roll 10, it is opened and placed on both sides of the paper tube of the material roll 10. Then, the clamping plate 7 closes the material roll 10, and the air-expanding brake sleeve is engaged inside the paper tube of the material roll 10. The material roll 10 rotates on the air-expanding brake sleeve to release the material.

[0041] The transport structure includes a motor 2, a synchronous belt 5, and a drive shaft 3. The motor 2 is located between the frames 1. The output shaft of the motor 2 drives the synchronous pulley 4 to drive the synchronous belt 5. The inner side of the synchronous belt 5 is provided with a guide rail 6 parallel to the synchronous belt 5. The guide rail 6 is provided with a suitable carrier receiving frame 602 for supporting the material roll 10. The side of the carrier receiving frame 602 is connected to the synchronous belt 5 through an L-shaped plate 601. When the motor 2 drives the synchronous pulley 4 and thus drives the synchronous belt 5 for transmission, the L-shaped plate 601 will then drive the carrier receiving frame 602 to move on the guide rail 6, thereby transporting the material roll 10 on the carrier receiving frame 602 to the position below the clamping plate 7.

[0042] The forks of the AGV trolley 8 place the material roll 10 pallet between the guide rails 6. The material roll pallet 9 includes a support plate 901, legs 903 at the bottom of the support plate 901, and support seats 902. Support seats 902 are provided on both sides of the upper surface of the support plate 901. The support seats 902 have downward arc-shaped material roll support. The distance between the support seats 902 is less than the length of the material roll 10. The total height of the legs 903, the thickness of the support plate 901, and the height of the support seats 902 is lower than the height of the carrier receiving frame 302 to the bottom. The material roll 10 is placed between the guide rails 6 through the material roll pallet 9 of the AGV trolley 8. Since the carrier receiving frame 602 is higher than the support seats 902, the material roll 10 is placed on the carrier receiving frame 602. Then, it is transported to the area below the clamping plate 7 through the guide rails 6 and the carrier receiving frame 602 for clamping and feeding.

[0043] When the material roll 10 placed on the material roll pallet 9 is transported to the guide rail 6 by the AGV trolley 8, the material roll pallet 9 is placed downwards, and the material roll 10 is positioned on both sides of the material roll pallet 9 and rests on the carrier receiving frame 602. Then, the motor 2 drives the synchronous belt 5 to slide the carrier receiving frame 602 on the guide rail 6 through the L-shaped plate 601 to the position below the clamping plate 7. The clamping plate 7 slides outwards on the guide rail d31 through the slider d30 and slides downwards on the guide rail e34 through the slider e33 to the sides of the material roll. Then, the clamping plate 7 tightens inwards and then moves upwards to unload the material roll 10. When the material roll 10 is unloaded and only the waste paper tube 12 remains;

[0044] The L-shaped rotating plate 15 is driven by cylinder 14. When cylinder 14 extends or retracts, the L-shaped rotating plate 15 rotates around the rotating rod 13. That is, the L-shaped rotating plate 15 drives the rotating rod 13 to rotate, thereby driving the gripper to rotate above the waste paper tube 12. The slider a17 is driven by cylinder a18 to slide on the guide rail a16, which can change the distance between the grippers to facilitate clamping the waste paper tube 12. The output end of cylinder c24 is connected to the base 28. When cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27. The connecting plate 27 drives the end of the gripper body 25. The gripper body 25 turns and rotates around the rotating shaft 26 to close inward, and the gripper body 25 is in a clamping state. In the first state, the waste paper tube 12 is clamped, and the slide plate 19 is driven by the cylinder b23. The slide plate 19 slides on the guide rail b21 on the base plate 22 via the slider b20, thereby changing the distance between the gripper and the waste paper tube 12. The output end of the cylinder c24 is connected to the base 28. When the cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27, and the connecting plate 27 drives the end of the gripper body 25. The gripper body 25 turns around the rotating shaft 26 and rotates inward to close. The gripper body 25 clamps the waste paper tube 12. The clamping plate 7 releases the waste paper tube 12. Then, the rotating rod 13 is rotated so that the gripper as a whole moves upward above the paper tube storage assembly 11, and then the gripper is released to complete one material change operation.
