Description

Technical Field

[0001] This invention belongs to the field of material handling equipment technology, and specifically relates to an AGV trolley that facilitates unloading. Background Technology

[0002] AGVs (Automated Guided Vehicles) are highly automated, flexible, and equipped with safety protection and various auxiliary mechanisms. Their working principle involves accurately navigating a predetermined path and completing designated tasks under the monitoring and task scheduling of a control computer. AGVs are primarily used for automated logistics and material handling. They automatically transport goods to designated locations using special landmark navigation. The most common guidance methods are magnetic strip guidance, laser guidance, and RFID guidance. Magnetic strip guidance is the most common and lowest-cost method, but it has limitations in site setup and can affect the overall aesthetics of the space. Laser guidance is the most expensive and has high site requirements, so it is generally not used. RFID guidance has a moderate cost and its advantages include high guidance accuracy, easier site setup to accommodate even the most complex layouts, no impact on the overall environment, and high security and stability that magnetic strip and laser navigation lack.

[0003] AGVs used to move goods onto shelves typically have multiple shelves to accommodate shelves of different heights. However, the shelves on AGVs are mostly fixed and cannot be adapted to a wider variety of shelf types. Furthermore, during unloading, it is impossible to ensure that the shelf and AGV are completely aligned, and the material may be suspended in mid-air, causing it to fall off. Summary of the Invention

[0004] The purpose of this invention is to provide an AGV trolley that facilitates unloading. It has multiple shelves for placing materials, and the height of each shelf can be freely adjusted. The shelves have integrated extension structures that can connect with the rack, avoiding material suspension during unloading and making material unloading more convenient.

The lead screw is threadedly connected to the connecting frame, and a bracket is fixed to the other side of the connecting frame.

[0012] In a preferred embodiment, a driven shaft is rotatably connected to the end of the bracket away from the connecting frame, and a driving shaft is rotatably connected to the end of the bracket near the connecting frame. A second material conveyor belt is installed on the outer side of the driving and driven shafts. A dual-axis motor is installed on the other side of the connecting frame and between the two brackets, with both ends of the dual-axis motor connected to the driving shaft.

[0013] In a preferred embodiment, the support assembly includes a support base slidably mounted on the upper surface of the trolley body. A movable seat is fixed at the center of the bottom of the support base. An adjustment groove is formed on the upper surface of the trolley body below the support base. The movable seat is located within the adjustment groove. A first transmission screw is rotatably connected to one side of the adjustment groove, and a guide rod is fixed to the other side of the adjustment groove. One end of the movable seat is threadedly connected to the first transmission screw, and the other end of the movable seat is slidably connected to the guide rod.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0038] Please see the appendix Figures 1 to 10 The AGV trolley shown is easy to unload and includes a main component 1. A support component 2 is provided on the top of one end of the main component 1. A lifting support frame 3 is fixed on the top of the other end of the main component 1. The lifting support frame 3 includes a lifting frame 31. Several movable material support trays 4 are installed on the inner side of the lifting frame 31. The material support trays 4 include lifting trays 41. The two ends of the lifting trays 41 are T-shaped and the lifting trays 41 are slidably connected to the lifting frame 31.

[0039] A fixed toothed plate 32 is vertically arranged on one side of the lifting frame 31, and a tooth 33 is vertically arranged inside the other side of the lifting frame 31. An electric push rod 47 is fixed to one end of the lifting support plate 41, and a toothed plate 48 is fixed to the output end of the electric push rod 47. One end of the toothed plate 48 is aligned with the electric push rod 47. A lifting motor 45 is fixed to the other end of the lifting support plate 41, and a lifting gear 46 is fixed to the output end of the lifting motor 45. The outer side of the lifting gear 46 is meshed with the tooth 33.

[0040] Insertion component 5 is disposed between support component 2 and lifting support frame 3. Insertion component 5 is located on the upper surface of main component 1, and one end of insertion component 5 is slidably connected to lifting support frame 3.

[0041] In the above-mentioned process, the support component 2 can support the material and transport the goods to the insertion component 5. When the material is transported to the insertion component 5, it is above the insertion component 5. By controlling the insertion component 5 to rise and fall on one side of the lifting support frame 3, the material can be moved in height. The appropriate material support plate 4 is selected to transfer the material to the material support plate 4. During unloading, the lifting motor 45 drives the lifting gear 46 to rotate. Under the action of the lifting gear 46 meshing with the teeth 33, the material support plate 4 moves up and down on the lifting frame 31. When the material support plate 4 moves to the appropriate height, the electric push rod 47 pushes the tooth plate 48 to move, so that the tooth plate 48 engages with the fixed tooth plate 32, thus fixing the height of the material support plate 4. At this time, the material support plate 4 is at the same height as the corresponding shelf, which makes it easier to unload the material.

[0042] In a preferred embodiment, please refer again. Figure 10 The material support pallet 4 also includes a material pallet 43, which is slidably connected to the upper surface of the lifting pallet 41. Both sides of the upper surface of the lifting pallet 41 are provided with sliding grooves. A second transmission screw 42 is rotatably connected inside one of the sliding grooves. A first motor is fixed inside the lifting pallet 41. The output end of the first motor is connected to the second transmission screw 42. Rotating shafts are rotatably connected to both ends inside the material pallet 43. A second motor is fixed to one end of one of the rotating shafts. A first material conveyor belt 44 is installed on the outside of the two rotating shafts. An anti-slip pad is provided on the surface of the first material conveyor belt 44.

[0043] As described above, when unloading materials onto the shelf, the material support plate 4 is raised and lowered as a whole to adjust it to the same height as the shelf. The first motor drives the second transmission screw 42 to rotate, which moves the material support plate 43 to one end, so that the material support plate 43 contacts the shelf. Then, the second motor drives the rotating shaft to rotate, which controls the first material conveyor belt 44 to rotate, transporting the materials to the shelf and completing the unloading of the materials.

[0044] Secondly, please refer to the following as well. Figure 6 and Figure 7 The insertion component 5 includes a connecting frame 51. Lifting blocks 52 are fixed at both ends on one side of the connecting frame 51. The lifting blocks 52 are slidably disposed on one side of the lifting frame 31. A lead screw is rotatably connected inside one side of the lifting frame 31. A third motor is fixed at the top of the lead screw. The lead screw is threadedly connected to the connecting frame 51. A bracket 53 is fixed on the other side of the connecting frame 51.

[0045] As described above, after receiving the material through the support component 2, the material is located above the support component 2 and is conveyed through the support component 2. When the material moves to the position above the bracket 53, the third motor can drive the lead screw to rotate, and under the action of the screw, the insertion component 5 can be lifted and lowered as a whole, thereby lifting the material located above the bracket 53.

[0046] Furthermore, a driven shaft 57 is rotatably connected to the end of the bracket 53 away from the connecting frame 51, and a driving shaft 56 is rotatably connected to the end of the bracket 53 near the connecting frame 51. A second material conveyor belt 54 is installed on the outside of the driving shaft 56 and the driven shaft 57. A dual-axis motor 55 is installed on the other side of the connecting frame 51 and between the two brackets 53. Both ends of the dual-axis motor 55 are connected to the driving shaft 56.

[0047] In this embodiment, when the control insertion component 5 moves to the same height as the corresponding material support tray 4, the dual-axis motor 55 is started. The dual-axis motor 55 drives the two active rotating shafts 56 to rotate. The active rotating shafts 56 drive the second material conveyor belt 54 to rotate. While rotating, the material can be moved to one end, so that the material can be moved to the material support tray 4 for temporary storage.

[0048] In a preferred embodiment, please refer again. Figure 4 and Figure 5The support assembly 2 includes a support base 21, which is slidably mounted on the upper surface of the trolley body 11. A movable seat 24 is fixed in the middle of the bottom of the support base 21. An adjustment groove is provided on the upper surface of the trolley body 11 below the support base 21. The movable seat 24 is located in the adjustment groove. A first transmission screw 22 is rotatably connected to one side of the adjustment groove. A guide rod 23 is fixed to the other side of the adjustment groove. One end of the movable seat 24 is threadedly connected to the first transmission screw 22. The other end of the movable seat 24 is slidably connected to the guide rod 23. A fourth motor is fixed at one end of the first transmission screw 22 inside the trolley body 11.

[0049] In this embodiment, when receiving materials, the first transmission screw 22 is driven to rotate by the fourth motor. Under the action of the screw, the movable seat 24 is moved. At the same time, the support seat 21 is moved to move horizontally, so that the support seat 21 is moved under the material and the material is placed on the support seat 21, thus supporting the material through the support seat 21.

[0050] Secondly, please refer to the following: Figure 4 and Figure 5 A rotary adjustment motor 25 is fixed in the middle of the interior of the movable base 24. A rotating disk 26 is fixed at the output end of the rotary adjustment motor 25. The top of the rotating disk 26 is fixed to the bottom of the support base 21. Adjusting rollers 27 are rotatably connected to both sides and both ends of the upper surface of the support base 21. A synchronous motor is fixed inside the support base 21. The output end of the synchronous motor is connected to the adjusting rollers 27.

[0051] As described above, when receiving materials, if the materials are placed at an angle, the rotating adjustment motor 25 can drive the rotating disk 26 to rotate. At the same time, the rotating disk 26 can rotate, thereby aligning the support base 21 with the materials when receiving them. This ensures that the materials are in the correct position when conveyed to the material support tray 4. When the materials are conveyed to the shelf through the material support tray 4, the materials can be arranged more neatly.

[0052] By controlling the rotation of the adjusting roller 27 located above the support 21, the material located above the support 21 can be moved on the support 21 when the adjusting roller 27 rotates, thereby moving the material to the center position of the support 21. In the subsequent conveying process, the material can be kept in the center position, ensuring that the material is placed more neatly when unloading.

[0053] For further details, please refer to the following: Figure 2 and Figure 3The main component 1 includes a trolley body 11. A first universal wheel 12 is rotatably connected to one end of the bottom of the trolley body 11. A second universal wheel 13 is rotatably connected to the two corners of the other end of the bottom of the trolley body 11. Drive wheels 14 are fixed on both sides of the bottom of the trolley body 11. Drive wheels 14 include a connecting plate 15. The connecting plate 15 is fixed to the bottom of the trolley body 11. A wheel frame 16 is fixed to the bottom of the connecting plate 15. A wheel drive motor 17 is fixed to one side of the wheel frame 16. A movable wheel 18 is installed at the output end of the wheel drive motor 17 and on the other side of the wheel frame 16.

[0054] In this embodiment, the main body component 1 can be moved by driving the moving wheel 18 to rotate through the wheel drive motor 17. At the same time, the steering can be completed by controlling the opening and closing of the two drive wheels 14 located on both sides. When the two wheel drive motors 17 control the moving wheel 18 to rotate in opposite directions, the main body component 1 can be controlled to rotate in place. The first universal wheel 12 and the second universal wheel 13 set at both ends can rotate adaptively according to the travel direction of the main body component 1, making the overall movement and steering of the device more flexible.

[0055] The working principle of this invention is as follows: During use, by controlling the movement of the main component 1, the support component 2 is positioned below the material. Then, by controlling the rotation of the first transmission screw 22, the moving seat 24 and the support seat 21 move together under the action of the screw thread. Next, the rotary adjustment motor 25 drives the rotating disk 26 to rotate, causing the support seat 21 to rotate and adjust it to correspond to the direction of the material, supporting the material on the support seat 21. Then, the rotary adjustment motor 25 is controlled again to rotate the support seat 21, resetting it and maintaining the material's orientation corresponding to the material support plate 4. Then, by controlling the rotation of the adjusting roller 27, the position of the material above the support seat 21 can be adjusted, ensuring the material is centered on the support seat 21, facilitating subsequent material conveying. Finally, by controlling the rotation of the adjusting roller 27, the material is conveyed above the insertion component 5, and the insertion component 5 is controlled to... The material rises, causing it to rise to the same height as the corresponding material support tray 4. Then, the dual-axis motor 55 drives the active rotating shaft 56 to rotate, causing the second material conveyor belt 54 to rotate. This, in turn, moves the material on the insertion assembly 5 towards the material support tray 4, transferring the material to the tray. The control device then moves to the shelf where the material needs to be stored and controls the lifting motor 45 to drive the lifting gear 46 to rotate. The lifting gear 46 meshes with the teeth 33, adjusting the height of the material. When the material reaches the same height as the shelf storage area, the electric push rod 47 pushes the toothed plate 48 to engage with the fixed toothed plate 32 to fix the height of the material support tray 4. Then, the second transmission screw 42 is rotated to extend the material tray 43, making it contact the shelf. The first material conveyor belt 44 then rotates, transporting the material to the shelf, completing the material transport and loading / unloading process.

[0056] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
