Description

Technical Field

[0001] The present invention relates to the field of AGV material handling vehicles, in particular to a quick-docking AGV material handling vehicle. Background Art

[0002] An automated guided vehicle (AGV) is a transport vehicle equipped with an automatic electromagnetic guidance device or an automatic optical guidance device, capable of traveling along a prescribed path. It also features vehicle programming and parking systems, safety protection, and various other features. [The text then abruptly shifts topics.] Moving loads. In recent years, with the rapid development of modern logistics and related technologies in my country, AGVs have been widely used in logistics and flexible manufacturing systems, significantly improving production automation and efficiency thanks to their high efficiency, speed, and flexibility. Laser guidance, an advanced guidance method adopted in the mid-1990s, is a unique method other than GPS that requires no land preparation. Laser AGVs utilize laser scanners and reflectors pre-installed around the AGV's operating area as the foundation for laser positioning, primarily performing tasks such as path planning, positioning, and obstacle avoidance.

[0003] However, the AGV material handling vehicles currently in use often require the cargo to be boxed when docking between different rail-mounted vehicles. Materials on different rail-mounted vehicles are exchanged and transported using tote boxes of limited sizes. Therefore, these rail-mounted vehicles require workers to box the cargo before warehousing, transportation, and outbound operations. This presents certain limitations and needs improvement. Summary of the Invention

[0004] In order to improve the problem in the related art that the AGV material handling trolley requires workers to pack the goods before exchanging and transporting them during the transportation process, which leads to certain limitations on the use environment, the present invention provides a quick-docking AGV material handling trolley.

[0005] The present invention provides a quick docking AGV material handling vehicle that adopts the following technical solutions: A quick-docking AGV material handling trolley comprises a vehicle body, a carrying plate is provided on the top wall of the vehicle body, an interaction groove is provided on one side of the carrying plate, an interaction rod is inserted in the interaction groove, the interaction rod is a rod-shaped structure with a semicircular cross-section, a material plate for placing materials is provided on the top wall of the interaction rod, a material groove is provided on the top wall of the carrying plate, the material plate is inserted in the material groove, a lifting mechanism is provided on the inner side wall of the interaction groove, the lifting mechanism is used to control the movement of the interaction rod in the vertical direction, a rotating groove is provided on the inner side wall of the interaction groove, a rotating mechanism is provided in the rotating groove, and the rotating mechanism is used to control the rotation of the interaction rod.

[0006] By adopting the above technical solution, when the quick-docking AGV material handling cart in the present invention is in use, when transporting goods in a storage building, the operator only needs to place the goods stably on the material board, and the cart can drive the materials to move. When the position of the materials needs to be adjusted, that is, when the goods need to be docked by the cart, after the two carts are close, a pair of interactive rods are close to each other. At this time, the lifting mechanism drives the interactive rods to move upward. After the pair of interactive rods move upward, the rotating mechanism controls the pair of interactive rods to rotate, and causes the pair of material boards to rotate synchronously, thereby realizing the patent of the materials on the material board. During the use of the material handling cart in the present invention, when facing goods of different sizes, specifications and shapes, it can be directly rotated without manual packing by the operator, which increases the applicability of the material cart in transporting materials.

[0007] Optionally, the lifting mechanism includes a lifting gear, an annular gear plate and a pushing cylinder. A lifting groove is provided on the inner side wall of the supporting plate. The pushing cylinder is located in the lifting groove. The lifting gear is arranged at the output end of the pushing cylinder. The annular gear plate is arranged on the side wall of the interactive rod close to the lifting gear. The annular gear plate is meshed with the lifting gear.

[0008] By adopting the above technical solution, when the interactive rod needs to be lifted, the operator only needs to control the pushing cylinder so that the pushing cylinder drives the lifting gear to move toward the interactive rod until the lifting gear engages with the annular gear plate, and then drives the lifting gear so that the lifting gear drives the annular gear plate to move, thereby driving the interactive rod to slide, thereby realizing the detachment of the material plate from the material trough.

[0009] Optionally, a stabilizing groove is provided on the side wall of the interactive rod, a connecting groove is provided on the side wall of the supporting plate, a connecting electromagnet is provided on the inner side wall of the connecting groove, a connecting spring is provided on the inner side wall of the connecting groove, the connecting spring is sleeved on the outside of the connecting electromagnet, a stabilizing plate is provided on the end of the connecting spring away from the connecting magnet, the stabilizing plate is inserted into the stabilizing groove, an adsorption magnet is provided on the end of the stabilizing plate close to the connecting electromagnet, and the connecting electromagnet and the adsorption magnet are magnetically attracted to each other.

[0010] By adopting the above technical solution, when the lifting gear drives the interactive rod to lift, the stabilizing slot moves to the position of the connecting slot as the interactive rod moves upward. At this time, the connecting electromagnet is powered off, and under the action of the connecting spring, the stabilizing plate is abutted and inserted into the connecting slot, thereby further stabilizing the interactive rod through the stabilizing plate, thereby improving the stability of the interactive rod after it moves upward.

[0011] Optionally, a driving groove is provided on the side wall of the supporting plate, a driving motor is provided in the driving groove, a driving gear is provided at the output end of the driving motor, a connecting tooth is provided on the side wall of the interactive rod, and the driving gear is meshed with the connecting tooth.

[0012] By adopting the above technical solution, the operator drives the driving gear to rotate through the driving motor, thereby driving the connecting gear to rotate by meshing the driving gear with the connecting gear, and then driving the interactive rod to rotate. When the two transport carts approach, a pair of interactive rods fit together, so that the pair of interactive rods can be driven to rotate by the driving gear and the connecting gear, thereby realizing the replacement of the interactive rod and the material plate.

[0013] Optionally, a linkage cavity is provided on the inner side wall of the interaction groove, and the linkage cavity is connected to the driving groove. A sliding groove is provided on the inner side wall of the linkage cavity, and a sliding block is slidably connected in the sliding groove. A guide block is provided at one end of the sliding block close to the interaction rod, and the guide block is rotatably connected to the side wall of the interaction rod through a connecting rod. The guide block is inclined toward the sliding direction of the interaction rod near the side wall of the interaction rod, and a shift groove is provided on the side wall of the guide block close to the interaction rod, and a shift block is provided in the shift groove. The drive motor is fixedly connected to the shift block, and the drive motor is against the bottom wall of the drive groove.

[0014] By adopting the above technical solution, when the interactive rod moves upward, the interactive rod drives the connecting rod to move upward, thereby driving the guide block to move upward through the connecting rod. Since the guide block is inclined close to the side wall of the interactive rod, as the guide block moves, the drive motor gradually approaches the direction of the interactive rod, and then the drive gear gradually approaches the interactive rod. When the interactive rod moves up to a certain extent, the drive gear engages with the connecting tooth, thereby reducing the possibility that the interactive rod is stuck and cannot move up due to the close distance between the drive gear and the interactive rod.

[0015] Optionally, a locking hole is provided on the side wall of the interactive rod, a fixing hole is provided on the inner wall of the interactive groove, a locking plate is provided in the fixing hole, the locking plate is rotatably connected to the inner wall of the fixing hole, the locking plate is inserted in the locking hole, and the locking plate is adapted to fit the locking hole.

[0016] By adopting the above technical solution, the structure of the locking plate and the locking hole increases the stability when the interactive rod and the interactive groove are naturally connected in the case of non-material transfer.

[0017] Optionally, a control groove is provided on the side wall of the locking plate, and an auxiliary groove is provided on the side wall of the supporting plate. An auxiliary rod is provided in the auxiliary groove, and the auxiliary rod is inserted into the control groove. The diameter of the auxiliary rod close to the locking plate is smaller than the diameter of the end away from the locking plate. When the auxiliary rod slides toward the locking plate, the locking plate rotates out of the locking hole.

[0018] By adopting the above technical solution, when the locking plate needs to be opened, it is only necessary to move the auxiliary rod so that the auxiliary rod slides toward the locking plate. Since the diameter of the auxiliary rod close to the locking plate is smaller than the diameter of the end away from the locking plate, when the auxiliary rod moves, the locking plate is gradually pushed up by the auxiliary rod, thereby disengaging from the locking hole, thereby making the interactive rod movable.

[0019] Optionally, a shift rod is provided on the side wall of the auxiliary rod, and one end of the shift rod away from the auxiliary rod is connected to the output end of the pushing cylinder.

[0020] By adopting the above technical solution, the shift rod is moved by pushing the cylinder, thereby driving the auxiliary rod to move, and then the opening and closing state of the locking plate is controlled by the auxiliary rod, and energy is effectively saved through linkage.

[0021] Optionally, an annular groove is provided on the top wall of the supporting plate, an annular plate is arranged in the annular groove, the annular plate is moved by a cylinder control, the annular plate is slidingly connected to the annular groove, a receiving groove is provided on the top wall of the annular plate, a receiving steel ball is arranged in the receiving groove, and the side wall of the receiving steel ball is against the bottom wall of the material plate.

[0022] By adopting the above technical solution, the structure of the bearing plate makes it difficult for the material plate to be folded or damaged if a heavy object is placed on it. The structure of the bearing steel ball makes the material plate more stable when rotating with the interactive rod.

[0023] In summary, the present invention has at least one of the following beneficial effects: When the quick-docking AGV material handling trolley of the present invention is in use, when transporting goods in a storage building, the operator only needs to place the goods stably on the material board, and the trolley can drive the materials to move. When the position of the materials needs to be adjusted, that is, when the goods need to be docked by the trolley, the two trolleys are close to each other, and a pair of interactive rods are close to each other. At this time, the lifting mechanism drives the interactive rods to move upward. After the pair of interactive rods move upward, the rotating mechanism controls the pair of interactive rods to rotate, and causes the pair of material boards to rotate synchronously, thereby realizing the patent of the materials on the material board. During the use of the material handling trolley of the present invention, when facing goods of different sizes, specifications and shapes, it can be directly rotated without manual packing by the operator, which increases the applicability of the material trolley in transporting materials.

[0025] The following is combined with Figure 1-5 The present invention is described in further detail.

[0026] The embodiment of the present invention discloses a quick docking AGV material handling vehicle. Figure 1 and Figure 2A quick-docking AGV material handling vehicle includes a running body 1, and a carrying plate 11 is provided on the top wall of the running body 1. The carrying plate 11 is a rectangular plate-shaped structure. An interactive groove 12 is provided on one side wall of the carrying plate 11, and the interactive groove 12 is a groove structure with a semicircular cross-section. An interactive rod 13 is inserted in the interactive groove 12, and the interactive rod 13 is adapted to be arranged with the interactive groove 12. A material plate 14 is integrally formed on the top wall of the interactive rod 13, and a material trough 15 is provided on the top wall of the material plate 14, and the material plate 14 is inserted in the material trough 15, and the material plate 14 is adapted to be arranged with the material trough 15. The material plate 14 is used to place materials. An annular groove 51 is provided on the top wall of the carrying plate 11, and an annular cylinder is provided on the bottom wall of the annular groove 51. An annular plate 52 is welded and fixed to the output end of the annular cylinder. The annular plate 52 is inserted in the annular groove 51, and the annular plate 52 is slidably connected to the annular groove 51. Driven by the annular cylinder, the annular plate 52 moves in the vertical direction in the annular groove 51. A receiving groove 53 is provided on the top wall of the annular plate 52 along the arc direction of the annular groove 51, and a receiving steel ball 54 is rotatably connected to the inner side wall of the receiving groove 53. The receiving steel ball 54 is in contact with the bottom wall of the material plate 14 and is used to lift the material plate 14, thereby increasing the stability of the material plate 14 itself.

[0027] Reference Figure 1 and Figure 3 A lifting groove 23 is formed on the inner side wall of the carrier plate 11 near the interactive groove 12, and the lifting groove 23 is connected to the interactive groove 12. A lifting mechanism 16 is disposed in the lifting groove 23, and the lifting mechanism 16 is used to drive the interactive rod 13 upward. The lifting mechanism 16 includes a lifting gear 2, an annular gear plate 21, and a push cylinder 22. The push cylinder 22 is disposed in the lifting groove 23 and is fixedly connected to the inner side wall of the lifting groove 23. The output end of the push cylinder 22 is fixedly connected to the push rod. The lifting gear 2 is disposed at the end of the push rod away from the push cylinder 22, and the lifting gear 2 is disposed vertically. The annular gear plate 21 is fixedly mounted on the side wall of the interactive rod 13, and the annular gear plate 21 is meshed with the lifting gear 2. When the interactive rod 13 needs to be lifted, the cylinder 22 is pushed to drive the lifting gear 2 to move toward the interactive rod 13 until the lifting gear 2 is meshed with the annular gear plate 21. The lifting gear 2 is then driven to cause the lifting gear 2 to drive the annular gear plate 21 to move, thereby driving the interactive rod 13 to slide, thereby achieving the separation of the material plate 14 from the material trough 15.

[0028] Reference Figure 3The side wall of the interactive lever 13 is provided with a stabilizing groove 24, which is an annular groove structure and surrounds the side wall of the interactive lever 13. A connecting groove 25 is provided on the side wall of the support plate 11, connecting groove 25 being connected to the interactive groove 12 and located below the lifting groove 23. A connecting electromagnet 26 is fixedly connected to the inner side wall of the connecting groove 25. A connecting spring 27 is mounted on the outer surface of the connecting electromagnet 26. The connecting spring 27 is located within the connecting groove 25, with one end of the connecting spring 27 connected to the inner side wall of the connecting groove 25 and a stabilizing plate 28 welded to the other end. When the interactive lever 13 is not raised, the stabilizing plate 28 abuts against the side wall of the interactive lever 13, and the connecting spring 27 is in a compressed state. When the interactive lever 13 is raised, the stabilizing plate 28, under the action of the connecting spring 27, abuts and inserts into the stabilizing groove 24. An adsorption magnet 29 is fixedly connected to the end wall of the stabilizing plate 28 near the connecting electromagnet 26. When the connecting electromagnet 26 is powered on, it is magnetically attracted to the adsorption magnet 29. Therefore, when the material plate 14 is lifted by the interactive rod 13, the connecting electromagnet 26 is de-energized, thereby separating the connecting electromagnet 26 from the adsorption magnet 29, and the connecting spring 27 is reset to insert the stabilizing plate 28 into the stabilizing groove 24, thereby supporting the material plate 14 and increasing the stability of the material plate 14 after it is lifted.

[0029] Reference Figure 1 and Figure 3 A drive slot 3 is defined on the side wall of the carrier plate 11 near the interactive rod 13, and a linkage cavity 4 is defined on the inner side wall of the interactive slot 12. The drive slot 3, linkage cavity 4, and connection slot 25 are all interconnected. A sliding slot is defined on the inner side of the linkage slot, into which a sliding block is inserted and slidably connected. A guide block 41 is welded and fixed to the side wall of the sliding block near the interactive rod 13. The guide block 41 has a triangular cross-section. A connecting rod 55 is welded and fixed to the side wall of the interactive rod 13 near the guide block 41. The bottom wall of the guide block 41 is fixedly connected to the connecting rod 55. The guide block 41 rises and falls with the rise and fall of the interactive rod 13. A shift slot 42 is defined on the side wall of the guide block 41 near the interactive rod 13. A shift block 43 is inserted into the shift slot 42. A drive motor 31 is fixedly connected to the shift block 43 on the side wall near the interactive rod 13. The drive motor 31 is located in the drive slot 3, and a drive gear 32 is mounted on the output end of the drive motor 31. The sidewall of the interactive lever 13 is provided with engaging teeth 33, and the drive gear 32 is meshed with the engaging teeth 33. When the interactive lever 13 moves upward, it drives the connecting rod 55 upward, thereby driving the guide block 41 upward through the connecting rod 55. Because the guide block 41 is tilted near the sidewall of the interactive lever 13, as the guide block 41 moves, the drive motor 31 gradually approaches the interactive lever 13, which in turn causes the drive gear 32 to gradually approach the interactive lever 13. When the interactive lever 13 moves upward to a certain extent, the drive gear 32 meshes with the engaging teeth 33.

[0030] Reference Figure 4 and Figure 5 A shift rod 49 is fixedly connected to the side wall of the push cylinder 22. An auxiliary rod 48 is welded to the end of the shift rod 49 away from the push cylinder 22. A locking hole 44 is defined in the side wall of the interactive lever 13. A fixing hole 45 is defined in the inner side wall of the interactive slot 12, and the fixing hole 45 is connected to the locking hole 44. A locking plate 441 is rotatably connected to the fixing hole 45 via a rotating shaft and inserted into the locking hole 44. A control slot 46 is defined in the side wall of the locking plate 441, and the auxiliary rod 48 is inserted into the control slot 46. The diameter of the auxiliary rod 48 at the end closest to the locking plate 441 is smaller than the diameter at the end farther from the locking plate 441. When the auxiliary rod 48 moves toward the locking plate 441 driven by the push cylinder 22, it lifts the locking plate 441 from the locking hole 44, thereby unlocking the interactive lever 13.

[0031] The implementation principle of a quick-docking AGV material handling vehicle according to an embodiment of the present invention is as follows: When the quick-docking AGV material handling vehicle according to the present invention is docking and transporting materials, first, the two handling vehicles are brought close together, and the pair of interactive rods 13 are aligned through the positioning system. Then, the push cylinder 22 drives the lifting gear 2 to approach the interactive rod 13. At the same time, the auxiliary rod 48, driven by the push cylinder 22, gradually lifts the locking plate 441 from the locking hole 44. When the lifting gear 2 moves to engage with the annular gear plate 21, the lifting gear 2 rotates and drives the pair of interactive rods 13 to rise simultaneously, and the material plate 14 is subsequently lifted from the material trough 15. As the interactive rod 13 rises, the interactive rod 13 drives the connecting rod 55 to move upward, thereby driving the guide block 41 to move upward through the connecting rod 55. Since the guide block 41 is tilted near the side wall of the interactive rod 13, as the guide block 41 moves, the drive motor 31 gradually approaches the interactive rod 13, thereby causing the drive gear 32 to gradually approach the interactive rod 13, and the drive gear 32 engages with the engagement gear 33. After the drive gear 32 rotates, the engagement gear 33 rotates, thereby causing the pair of interactive rods 13 to rotate, and causing the pair of interactive rods 13 to change position together with the material plate 14, thereby completing the transfer of the material carried on the material plate 14. During use, the material handling trolley of the present invention can directly rotate when facing goods of different sizes, specifications, and shapes without the operator having to manually pack them, thereby increasing the applicability of the material trolley in handling materials.

[0032] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
