Description

Technical Field

[0001] This invention relates to the field of AGV conveying technology, and more specifically to an AGV material conveying device for material transfer and conveying. Background Technology

[0002] Automated Guided Vehicles (AGVs) are transport vehicles equipped with electromagnetic or optical automatic guidance devices, enabling them to travel along a predetermined guide path. They possess safety protection and various transfer functions, and in industrial applications, they do not require a driver. They are powered by rechargeable batteries. Their movement and behavior are typically controlled by a computer, or their path can be established using an electromagnetic path-following system. This system is attached to the floor, and the AGV moves and operates according to the information conveyed by the electromagnetic track.

[0003] AGVs, characterized by wheeled movement, offer advantages over walking, crawling, or other non-wheeled mobile robots, including faster movement, higher efficiency, simpler structure, stronger controllability, and better safety. Compared to other equipment commonly used in material handling, AGVs do not require fixed devices such as tracks or support frames, and are not limited by site, road, or space constraints. Therefore, in automated logistics systems, they best demonstrate their automation and flexibility, enabling efficient, economical, and flexible unmanned production.

[0004] Currently, common AGVs typically have only one cargo platform, and sometimes the platform can only transport one material box. However, for certain industries, such as garment processing, the materials that need to be handled or transported are relatively light. If the AGV only transports one material box at a time, its transport efficiency is very low. Furthermore, during the material transport process, the materials are piled up in an open manner on the AGV's cargo platform. If an obstacle appears in front of the AGV during movement, the AGV can automatically stop or avoid it. During this process, the materials on the AGV will move or shake due to inertia. If the materials are piled up high, there is a risk of them falling. There is no protective structure for the materials.

[0005] Therefore, the present invention provides an AGV material conveying device for material transfer and conveying to solve the above-mentioned problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides an AGV material conveying device for material transfer and transportation, so as to solve the problem mentioned in the background art that the common AGV trolley has only one cargo platform and can only transport one material box at a time, and has no protective structure for the material.

[0042] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figure 1 To be continued Figure 15 As will be clearly shown in the detailed description of the embodiments, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] Example 1: This invention is an AGV material conveying device for material transfer and transportation, as shown in the attached figure. Figures 1-15As shown, the AGV includes an AGV trolley 1, which is an existing product. The AGV trolley is equipped with a power supply and an intelligent controller. The bottom of the AGV trolley 1 has a loading and unloading chute 2 with a front opening. A loading and unloading translation component 3 is slidably installed inside the loading and unloading chute 2. The loading and unloading translation component 3 can move forward from the loading and unloading chute 2 to the front of the AGV trolley 1. A loading and unloading lifting component 4 is installed on the top of the loading and unloading translation component 3, which moves up and down. The material is placed on the top of the loading and unloading lifting component 4. The loading and unloading lifting component 4 can move up and down on the top of the loading and unloading translation component 3. In use, the AGV trolley can move to one side of the material, and then move the loading and unloading translation component 3 forward to the bottom of the material, and then lift the material by the loading and unloading lifting component 4.

[0045] The AGV trolley 1 has a material loading slot 5 with a front opening on its top. A telescopic U-shaped plate assembly 6 is fixedly installed on the top surface of the AGV trolley 1, located outside the material loading slot 5. The front opening of the telescopic U-shaped plate assembly 6 is used to protect the left, right, and rear sides of the material on the AGV trolley 1. The telescopic U-shaped plate assembly 6 can be vertically extended and retracted to adjust its height. A multi-layer material loading assembly 7 located inside the material loading slot 5 is connected to the top of the telescopic U-shaped plate assembly 6. In use, the loading and unloading lifting assembly 4 lifts the material upwards until the bottom surface of the material is flush with the top surface of the multi-layer material loading assembly 7. Then, the loading and unloading lifting assembly 4 moves the material to the top of the multi-layer material loading assembly 7, thus completing the material loading operation. The material assembly 7 consists of multiple layers of material carrier plates 32, and each layer of material carrier plate 32 can move upward as the height of the telescopic U-shaped plate assembly 6 is adjusted. Therefore, when the material is placed on the uppermost material carrier plate 32, the telescopic U-shaped plate assembly 6 can be moved upward, thereby driving the uppermost material carrier plate 32 and the material it carries to move upward, so that the second layer of material carrier plate 32 moves to a position flush with the top surface of the AGV trolley 1. Then, the subsequent material is moved onto the material carrier plate 32 by the loading and unloading translation assembly 3 and the loading and unloading lifting assembly 4, thereby realizing the handling and conveying of multiple materials through the multi-layer material carrier assembly 7. After the loading and unloading translation assembly 3 and the loading and unloading lifting assembly 4 move into the loading and unloading chute 2, the AGV trolley 1 can convey the material.

[0046] During unloading, the loading and unloading translation component 3 moves outward, and the loading and unloading lifting component 4 rises to a position flush with the loading plate 32. The loading plate 32 can move the material on it to the top of the loading and unloading lifting component 4, and then the loading and unloading lifting component 4 lowers to place the material on the ground to complete the unloading.

[0047] The top of the telescopic U-shaped plate group 6 and the bottom surface of the material loading plate groove 5 are slidably installed with protective components 8 on the left and right sides of the material. The protective components 8 can move relative to each other on the left and right sides of the material. When the protective components 8 move towards the center, they can clamp and protect the material, preventing the material from shaking or falling when the AGV trolley moves.

[0048] Example 2, based on Example 1, as shown in the appendix. Figure 5 Appendix Figure 7 -Appendix Figure 9 Appendix Figure 13 Appendix Figure 14 As shown, the loading and unloading translation assembly 3 includes a loading and unloading translation plate 9, a translation chute 10, a translation slider 11, a translation lead screw 12, and a translation support wheel 13;

[0049] The loading and unloading chute 2 has a loading and unloading translation plate 9 that is slidably installed back and forth inside. The loading and unloading chute 2 has translation chute 10 on both the left and right sides. Each translation chute 10 has a translation slider 11 that is slidably installed back and forth on its front side. The two translation sliders 11 are fixedly connected to the rear ends of the left and right sides of the loading and unloading translation plate 9, respectively. The two translation chute 10 have a translation screw 12 that passes through the translation slider 11 and is threadedly engaged with it. The loading and unloading translation plate 9 has a translation support wheel 13 installed at its bottom.

[0050] When the two translation screws 12 rotate synchronously, they can drive the two translation sliders 11 to slide back and forth in the translation groove 10, thereby driving the loading and unloading translation plate 9 to slide back and forth. When the loading and unloading translation plate 9 moves to the outside of the AGV trolley 1, it is supported by the translation support wheel 13 installed at its bottom.

[0051] Example 3, based on Example 2, as shown in the appendix. Figure 8 Appendix Figure 9 Appendix Figure 13 As shown, each of the two translation screws 12 has a translation sprocket 14 fixedly mounted coaxially at its rear end. A translation chain 15 is installed between the two translation sprockets 14. One of the translation screws 12 is connected to a translation drive motor 16 fixedly installed inside the corresponding translation groove 10. The translation drive motor 16 is electrically connected to the power supply and the controller. When the translation drive motor 16 starts, it can drive the two translation screws 12 to rotate simultaneously through the cooperation of the translation sprocket 14 and the translation chain 15, thereby realizing the movement of the loading and unloading translation plate 9.

[0052] Example 4, based on Example 3, as shown in the appendix. Figure 7 -Appendix Figure 14As shown, the loading and unloading lifting assembly 4 includes a loading and unloading lifting plate 17, a lifting chute 18, a lifting bidirectional lead screw 19, a lifting screw block 20, a lifting connecting rod 21, a lifting drive motor 22, a lifting sprocket 23, and a lifting chain 24.

[0053] A loading and unloading lifting plate 17 is placed on top of the loading and unloading translation plate 9. Two lifting grooves 18, symmetrically arranged about its centerline, are formed on the top of the loading and unloading translation plate 9. A lifting bidirectional lead screw 19 is rotatably installed in each of the two lifting grooves 18. The threads at both ends of each lifting bidirectional lead screw 19 are in opposite directions. Two lifting screw blocks 20, respectively connected to the threads at both ends of the lifting bidirectional lead screw 19, are slidably installed in each of the lifting grooves 18. (See attached diagram.) Figure 10 As shown, when the loading and unloading lifting plate 17 is in contact with the top surface of the loading and unloading translation plate 9, the two lifting screw blocks 20 are in the middle of the lifting bidirectional screw rod 19. Each of the lifting screw blocks 20 is hinged to the top of a lifting connecting rod 21, and the other end of each of the lifting connecting rods 21 is hinged to the bottom of the loading and unloading lifting plate 17.

[0054] A lifting drive motor 22 is fixedly installed at the rear end of the top surface of the loading and unloading translation plate 9. The lifting drive motor 22 is electrically connected to the power supply and controller. The rear ends of the two lifting bidirectional lead screws 19 pass through the rear side of the loading and unloading translation plate 9 and are coaxially fixedly installed with lifting sprockets 23. The lifting drive motor 22 is also coaxially fixedly installed with lifting sprockets 23. Lifting chains 24 are installed between the multiple lifting sprockets 23.

[0055] In use, when the loading and unloading transfer plate 9 moves to the outside of the AGV trolley 1, it can drive the loading and unloading lifting plate 17 to move synchronously to the bottom of the material. Then, it can drive the lifting drive motor 22, and through the cooperation of the lifting sprocket 23 and the lifting chain 24, the two lifting double screws 19 rotate synchronously. This causes the two lifting screw blocks 20 in each lifting groove 18 to move to the two ends of the lifting double screw 19 respectively, and lift the loading and unloading lifting plate 17 upward through the lifting connecting rod 21, thereby lifting the material upward so that the bottom of the material is flush with the top surface of the loading plate 32. Alternatively, the loading and unloading transfer plate 9 and the loading and unloading lifting plate 17 can be set as two, such as in a forklift shape, to facilitate the lifting of materials.

[0056] Example 5, based on Example 4, as shown in the appendix. Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 9 -Appendix Figure 14As shown, the top of the loading and unloading lifting plate 17 is provided with a loading and unloading roller groove 25. Multiple loading and unloading rollers 26, arranged equidistantly, are rotatably mounted within the loading and unloading roller groove 25. The outer surfaces of the multiple loading and unloading rollers 26 are flush with the top surface of the loading and unloading lifting plate 17. A roller sprocket 27 is coaxially fixedly mounted on one end of each of the multiple loading and unloading rollers 26 on the same side. A roller chain 28 is installed between the multiple roller sprockets 27. The top of the loading and unloading lifting plate 17 is provided with a roller motor groove, and a component connected to one of the loading and unloading rollers 26 is fixedly mounted within the roller motor groove. The drive motor 29 is electrically connected to the power supply and controller. When the drive motor 29 is started, it drives the loading and unloading rollers 26 connected to it to rotate. Through the cooperation of multiple roller sprockets 27 and roller chains 28, the multiple loading and unloading rollers 26 can rotate synchronously. When the material is on top of the loading and unloading lifting plate 17 and is lifted to a position where the bottom of the material is flush with the loading plate 32, the drive motor 29 can be started to make the multiple loading and unloading rollers 26 rotate, thereby moving the material towards the loading plate 32, and finally moving the material to the top of the loading plate 32 for placement.

[0057] Example 6, based on Example 1, as shown in the appendix. Figure 1 -Appendix Figure 3 Appendix Figure 7 Appendix Figure 11 -Appendix Figure 13 As shown, the telescopic U-shaped plate assembly 6 is composed of multiple U-shaped plates with a "U"-shaped cross-section that are installed in a stepwise manner. Each U-shaped plate has a telescopic groove on its top for sliding installation of the U-shaped plate above it. The thickness of the multiple U-shaped plates decreases from bottom to top. Each U-shaped plate can slide inside the telescopic groove on the top of the U-shaped plate below it, thereby enabling the telescopic U-shaped plate 6 to achieve height adjustment. A telescopic drive plate 30 is installed on the top of the uppermost U-shaped plate. A telescopic drive hydraulic cylinder 31 is installed on the top of the AGV trolley 1, located outside the telescopic U-shaped plate assembly 6. The telescopic drive hydraulic cylinder 31 is fixedly connected to the telescopic drive plate 30. The telescopic drive hydraulic cylinder 31 is connected to a controller and a hydraulic oil pump. When the telescopic drive hydraulic cylinder 31 is started, its telescopic end extends, which can drive the telescopic drive plate 30 to move upward, thereby causing the telescopic U-shaped plate 6 to extend upward.

[0058] Example 7, based on Example 1, as shown in the appendix. Figure 1 Appendix Figure 3 -Appendix Figure 5 Appendix Figure 7 Appendix Figure 11 Appendix Figure 13 Appendix Figure 15As shown, the multi-layer material loading assembly 7 includes multiple material loading plates 32, material loading ropes 33, material loading force plates 34, material loading force rings 35, and material loading force ropes 36.

[0059] Multiple material plates 32 arranged vertically are installed in the material plate groove 5. Each material plate 32 has a support plate installed on its top edge, so that there is a certain space between the multiple material plates 32. Each of the four corners of each pair of adjacent material plates 32 is fixedly connected to a material pull rope 33. When the multiple material plates 32 are inside the material plate groove 5, the material pull rope 33 is in a loose state. The front and rear ends of the top of the telescopic U-shaped plate group 6 are fixedly installed with material bearing plates 34. Each material bearing plate 34 has two material bearing rings 35 fixedly installed at its bottom. Each material bearing ring 35 has a material bearing rope 36 fixedly connected to it. The other ends of the four material bearing ropes 36 are fixedly connected to the four corners of the top surface of the uppermost material plate 32.

[0060] In use, after the loading and unloading lifting device 4 moves the material to the top of the uppermost loading plate 32, the telescopic U-shaped plate assembly 6 rises upward, thereby pulling the uppermost loading plate 32 and the material on top of it upward through the loading force rope 36 (as shown in the attached diagram). Figure 11 Appendix Figure 13 (as shown in the image) At the same time, the topmost material carrier 32 can gradually straighten the loose material pull ropes 33 connected to its four bottom corners, and move the second material carrier 32 upward to a position level with the top of the AGV trolley through the four material pull ropes 33. Then, wait for the loading and unloading lifting device 4 to move the subsequent materials to its top. In this way, the subsequent materials can be moved to the top of multiple material carriers 32 through the above method. The AGV trolley 1 can move multiple materials at the same time, and the telescopic U-shaped plate group 6 can protect the material carrier 32 in three directions to prevent the material carrier 32 from shaking.

[0061] Example 8, based on Example 7, as shown in the appendix. Figure 4 -Appendix Figure 6 Appendix Figure 15 As shown, each of the material carrier plates 32 has a transfer belt roller groove 37 at both its front and rear ends. A transfer belt roller 38 is rotatably installed in each of the transfer belt roller grooves 37. A transfer belt 39 located on the outer side of the top and bottom surfaces of the material carrier plate 32 is installed between the two transfer belt rollers 38. An anti-slip strip 40 is provided on the outer surface of the transfer belt 39. A pusher plate 41 is fixedly installed on the top surface of the transfer belt 39. A sensor 42 electrically connected to the power supply and controller is installed on the front side of the pusher plate 41. When the material carrier plate 32 is not carrying any material, the pusher plate 41 is at the front end of the material carrier plate 32.

[0062] A transfer drive motor 43 is installed at the rear end of the top surface of the material carrier plate 32. The transfer drive motor 43 is electrically connected to the power supply and controller. A transfer sprocket assembly is installed between the transfer drive motor 43 and the transfer belt roller 38 located at the rear end of the material carrier plate 32. The rotating shaft of the transfer drive motor 43 and the transfer belt roller 38 located at the rear end of the material carrier plate 32 are both coaxially fixedly installed with transfer sprockets. A transfer chain is installed between the two transfer sprockets. When the transfer drive motor 43 is started, it can drive the transfer belt roller 38 to rotate, thereby driving the transfer belt 39 to rotate.

[0063] In use, when the loading and unloading lifting plate 17 moves upward to bring the bottom of the material to a position flush with the top surface of the carrying plate 32, multiple loading and unloading rollers 26 rotate to move the material toward the carrying plate 32. When the rear end of the material moves to the front surface of the transfer belt 39, the material can contact the sensor 42 on the front side of the pusher plate 41. At this time, the transfer drive motor 43 starts, causing the transfer belt 39 and the loading and unloading rollers 26 to rotate synchronously. The transfer belt 39 then drives the pusher plate 41 and the material to move backward, so that the material moves to the innermost side of the telescopic U-shaped plate assembly 6 (see attached diagram for details). Figure 13 The transfer belt 39 is located in the middle of the carrier plate 32. If the width of the material is greater than the width of the transfer belt 39, the two ends of the bottom of the material will inevitably come into contact with the top surface of the carrier plate 32 (especially for softer materials, such as cardboard boxes). In order to avoid the friction between the material and the carrier plate 32 being greater than the friction between the material and the transfer belt 39, anti-slip strips 40 are provided on the surface of the transfer belt 39. This can prevent the material from slipping between the material and the transfer belt 39 and being unable to move to the innermost side of the telescopic U-shaped plate group 6.

[0064] When unloading is required, the loading and unloading lifting plate 17 is moved to a position flush with the loading plate 32, and then the material transfer drive motor 43 is started in reverse, causing the material transfer belt 39 to rotate in reverse, thereby driving the pusher plate 41 and the material to move forward and reset. The pusher plate 41 can also push the material. After the material moves to the top of the loading and unloading lifting plate 17, the loading and unloading lifting plate 17 moves downward to place the material on the ground.

[0065] Example 9, based on Example 8, as shown in the appendix. Figure 1 -Appendix Figure 3 Appendix Figure 5 Appendix Figure 7 Appendix Figure 13 As shown, the protective component 8 includes a protective adjustment plate 45, a protective adjustment groove 46, a protective slider 47, a protective telescopic rod 48, and a protective clearance groove 49.

[0066] The top of the telescopic U-shaped trough 6 is fixedly equipped with multiple protective adjustment plates 45 distributed equidistantly at the front and back. Each protective adjustment plate 45 has a protective adjustment groove 46 extending vertically through its left and right ends. A protective slider 47 is slidably installed in each protective adjustment groove 46. A protective telescopic rod 48 is fixedly installed at the bottom of each protective slider 47, and the bottom of the protective telescopic rod 48 is in contact with the bottom surface of the material loading plate trough 5. The left and right ends of the multiple material loading plates 32 are provided with protective clearance grooves 49 that allow the multiple protective telescopic rods 48 to move left and right. When all the material is placed on the top of the multiple material loading plates 32, the two protective sliders 47 on the multiple protective adjustment plates 45 can be moved towards the center, thereby driving the multiple protective telescopic rods 48 to move towards the center of the material loading plate 32 inside the protective clearance grooves 49. This achieves the function of clamping and protecting the left and right sides of the material, thereby preventing the material from shaking or falling during the moving and conveying process.

[0067] Example 10, based on Example 9, as shown in the appendix. Figure 1 -Appendix Figure 3 Appendix Figure 5 Appendix Figure 7 Appendix Figure 13 As shown, the protective telescopic rod 48 is composed of multiple telescopic slide rails with a cross-section of "U" that slide against each other. One side of the opening of the multiple telescopic slide rails is flush with each other, and anti-slip pads are provided on the flush side, which can increase the friction between the protective telescopic rod 48 and the left and right sides of the material.

[0068] A protective threaded plate 50 is fixedly installed between the tops of multiple protective sliders 47 located on the same side. A protective dual-axis motor 51 is fixedly installed on the top of one of the protective adjusting plates 45. The protective dual-axis motor 51 is electrically connected to the power supply and controller. Protective adjusting screws 52 are coaxially fixedly installed on the rotating shafts on both the left and right sides of the protective dual-axis motor 51 and are threadedly connected to the protective threaded plate 50 located on the same side. The thread directions of the two protective adjusting screws 52 are opposite.

[0069] When in use, starting the protective dual-axis motor 51 will drive the two protective adjusting screws 52 to rotate synchronously. The two protective adjusting screws 52 can then drive the two protective threaded plates 50 to move towards the center simultaneously, thereby driving multiple protective sliders 47 and protective telescopic rods 48 to move towards the center, achieving clamping and protection of the material on both sides.
