Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an automatic loading and unloading AGV trolley. Background Technology

[0002] With the intelligent development of the manufacturing industry, the demand for automation in production is increasing. For example, different raw materials are usually required when manufacturing on different production equipment. Currently, workers transfer different raw materials to different production equipment by handling them, which is inefficient and has high labor costs. Therefore, there is an urgent need for a device that can easily transfer and load materials between different equipment. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic loading and unloading AGV trolley to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] An automated guided vehicle (AGV) for loading and unloading includes: a vehicle body; a material storage mechanism disposed on the vehicle body, the material storage mechanism including a lifting frame movable in the vertical direction on the vehicle body, a hopper disposed on the lifting frame, a material inlet disposed on the top side of the hopper, a material outlet disposed on one side of the bottom of the hopper, a baffle plate disposed at the material outlet of the hopper that can open or close the material outlet, and a first discharge chute disposed on the bottom side of the hopper that can extend or retract from below the material outlet.

[0006] This technical solution has at least the following beneficial effects: The vehicle body serves as the basic frame for movement, and the lifting frame can move vertically on the vehicle body. When it is necessary to feed material into the hopper, the baffle plate is located at the discharge port, closing the discharge port. The lifting frame moves downward to lower the height of the hopper, making it easy to replenish material into the hopper. Then, the vehicle body moves to the target equipment where material needs to be fed, and the lifting frame moves upward to raise the hopper. Next, the first discharge chute extends from below the discharge port, reaching the position above the feeding port of the target equipment. The baffle plate moves away from the discharge port to open the discharge port. At this time, the material in the hopper can be discharged from the discharge port and fall into the feeding port of the target equipment through the first discharge chute. After feeding the target equipment, the first discharge chute retracts to below the discharge port. In this way, the material can be transferred to the hopper and then transferred to the target equipment, reducing the labor intensity of workers and production costs. The entire production process is more time-saving and efficient.

[0007] As a further improvement to the above technical solution, the lifting frame is equipped with a first motor and a first synchronous pulley. The first motor drives the first synchronous pulley. A second synchronous pulley is located outside the hopper. A first synchronous belt drives the first synchronous pulley and the second synchronous pulley. The first discharge chute is slidably connected to the outside of the hopper and connected to the first synchronous belt. When the first motor drives the first synchronous pulley to rotate, the first discharge chute can be extended or retracted from below the discharge port via the first synchronous belt. When discharge is required, the first motor operates, driving the first synchronous pulley to rotate and transmitting power to the first synchronous belt, causing the first synchronous belt to rotate on the first and second synchronous pulleys. Since the first discharge chute is connected to the first synchronous belt, as the first motor drives the first synchronous belt to rotate forward or reverse, the first discharge chute can be extended or retracted from below the discharge port.

[0008] As a further improvement to the above technical solution, a second discharge trough is slidably connected to the outside of the first discharge trough. A third synchronous pulley and a fourth synchronous pulley are spaced apart along the length of the first discharge trough. A second synchronous belt is connected between the third synchronous pulley and the fourth synchronous pulley. A fixed block is connected to the lifting frame. The fixed block is connected to one side of the second synchronous belt. The second discharge trough is connected to the other side of the second synchronous belt. When the first discharge trough slides relative to the lifting frame, it can be driven by the second synchronous belt to extend or retract the second discharge trough into the first discharge trough of the clearance groove. When the first discharge chute moves, the second synchronous belt on one side of the first discharge chute and the lifting frame form a fixed connection point, causing the second synchronous belt to rotate around the fixed block as a fulcrum. For example, when the first discharge chute extends out from below the discharge port, the second discharge chute can also extend out relative to the first discharge chute; when the first discharge chute is retracted back to the first discharge chute, the second discharge chute can also retract relative to the first discharge chute. In this way, the first discharge chute and the second discharge chute can form a two-stage extension and retraction on the bottom side of the hopper. When extending, it can extend to a longer length, and when retracting, it can be further retracted to the bottom side of the hopper.

[0009] As a further improvement to the above technical solution, the bottom surface of the hopper is inclined downwards along the direction close to the discharge port. The inclined bottom surface of the hopper helps to guide the material in the hopper to the discharge port, allowing for more complete discharge of the material in the hopper and improving material discharge efficiency.

[0010] As a further improvement to the above technical solution, the top two sides of the silo are inclined downwards towards the center of the silo. The silo forms a space that gradually increases in size at the top, which facilitates the entry of materials into the silo. After the materials enter the silo, they converge towards the center of the silo at the top, improving the flowability of the materials within the silo and allowing the materials in the silo to be discharged more effectively.

[0011] As a further improvement to the above technical solution, the top side of the baffle plate is hinged to the outside of the hopper, and a rotary drive is provided on the lifting frame. The rotary drive drives the baffle plate, which can rotate upward to open the discharge port or rotate downward to close the discharge port. When transferring and storing materials into the hopper, the rotary drive drives the baffle plate to rotate downward to close the discharge port, thereby preventing materials from being discharged from the hopper. When it is necessary to discharge materials from the hopper, the rotary drive drives the baffle plate upward to open the discharge port, at which time the materials can be discharged from the discharge port.

[0012] As a further improvement to the above technical solution, a vibrator is installed on the outside of the silo. When it is necessary to discharge the material from the silo, the vibrator operates, causing the silo to vibrate, which can improve the efficiency of material discharge from the silo and effectively reduce the accumulation of material inside the silo.

[0013] As a further improvement to the above technical solution, a material detection sensor is installed on the lifting frame, with the detection direction of the material detection sensor facing the discharge port. The material detection sensor can detect whether there is still material being discharged at the discharge port, which helps to ensure that the material in the hopper is completely discharged, thereby improving the accuracy of the amount of material fed into the target equipment.

[0014] As a further improvement to the above technical solution, a vertical frame is provided on the top side of the vehicle body, and a lifting drive source is provided inside the vertical frame. The lifting frame is slidably connected to the vertical frame, and the lifting drive source drives the lifting frame to slide up and down. The lifting drive source provides a driving force to the lifting frame to move in the vertical direction. When it is necessary to add material into the hopper, the lifting drive source drives the lifting frame to move downward on the vertical frame, thereby lowering the height of the hopper and facilitating the addition of material into the hopper. When it is necessary to pour the material in the hopper to the target equipment, the lifting drive source drives the lifting frame to move upward, thereby raising the hopper and facilitating the pouring of the material in the hopper through the discharge port to the target equipment.

[0015] As a further improvement to the above technical solution, the lifting drive source includes a second motor and a fifth synchronous pulley mounted on the vertical frame. Two fifth synchronous pulleys are spaced apart in the vertical direction. The second motor drives and connects to either of the fifth synchronous pulleys. A third synchronous belt connects the two fifth synchronous pulleys. The lifting frame is connected to the third synchronous belt. When the second motor drives the fifth synchronous pulley to rotate, the third synchronous belt can drive the lifting frame to slide upwards or downwards. The second motor can provide rotational driving force to the fifth synchronous pulleys, causing them to rotate. This, in turn, drives the third synchronous belt to rotate between the two fifth synchronous pulleys. At this time, the third synchronous belt can drive the lifting frame to slide upwards or downwards, thereby adjusting the height of the hopper. This allows for a significant adjustment of the hopper's position in the vertical direction and makes the overall structure more compact. Attached Figure Description

Detailed Implementation

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0022] Reference Figure 1 An automatic loading and unloading AGV trolley includes: a vehicle body 1, which is movable. Naturally, the bottom side of the vehicle body 1 is provided with drive wheels and steering wheels to enable movement between two devices; a storage mechanism, which is provided on the vehicle body 1. The storage mechanism includes a lifting frame 21 that can move vertically on the vehicle body 1 and a hopper 22 provided on the lifting frame 21. The top side of the hopper 22 is provided with a feed inlet 221, and the bottom side of the hopper 22 is provided with a discharge outlet. The hopper 22 is provided with a baffle plate 23 at the discharge outlet position that can open or close the discharge outlet. The bottom side of the hopper 22 is provided with a first discharge chute 241 that can extend or retract from below the discharge outlet.

[0023] In this automated guided vehicle (AGV), the vehicle body 1 serves as the basic frame, enabling movement. The lifting frame 21 can move vertically on the vehicle body 1. When material needs to be loaded into the hopper 22, the baffle 23 is positioned at the discharge port, closing the discharge port. The lifting frame 21 moves downward to lower the height of the hopper 22, facilitating material replenishment. Then, the vehicle body 1 moves to the target equipment requiring loading, and the lifting frame 21 moves upward to raise the hopper 22. Next, the first discharge chute 241... Extending from below the discharge port to above the feeding port of the target equipment, the baffle plate 23 moves away from the discharge port to open it. At this time, the material in the hopper 22 can be discharged from the discharge port and fall into the feeding port of the target equipment through the first discharge chute 241. After feeding the target equipment, the first discharge chute 241 retracts to below the discharge port. In this way, the material can be transferred to the hopper 22 and then transferred to the target equipment, reducing the labor intensity of workers and production costs. The whole production process is more time-saving and efficient.

[0024] There are various structural forms that drive the first discharge trough 241 to move back and forth. For example, a linear drive can be used to drive the first discharge trough 241 to move. In this embodiment, such as... Figure 2As shown, the lifting frame 21 is equipped with a first motor and a first synchronous pulley 242. The first motor drives the first synchronous pulley 242. A second synchronous pulley 243 is provided on the outside of the hopper 22. A first synchronous belt 244 drives the first synchronous pulley 242 and the second synchronous pulley 243. The first discharge chute 241 is slidably connected to the outside of the hopper 22 and is connected to the first synchronous belt 244. When the first motor drives the first synchronous pulley 242 to rotate, the first discharge chute 241 can be driven to extend or retract from below the discharge port through the first synchronous belt 244. When material needs to be discharged, the first motor works, driving the first synchronous pulley 242 to rotate and transmitting the power to the first synchronous belt 244, causing the first synchronous belt 244 to rotate on the first synchronous pulley 242 and the second synchronous pulley 243. Since the first discharge trough 241 is connected to the first synchronous belt 244, as the first motor drives the first synchronous belt 244 to rotate forward or reverse, the first discharge trough 241 can be driven to extend or retract from below the discharge port.

[0025] To extend the travel distance for guiding material out of the discharge port, in this embodiment, a second discharge trough 245 is slidably connected to the outside of the first discharge trough 241. A third synchronous pulley 246 and a fourth synchronous pulley 247 are spaced apart along the length of the first discharge trough 241. A second synchronous belt 248 is connected between the third synchronous pulley 246 and the fourth synchronous pulley 247. A fixing block is connected to the lifting frame 21. The fixing block is connected to one side of the second synchronous belt 248. The second discharge trough 245 is connected to the other side of the second synchronous belt 248. When the first discharge trough 241 slides relative to the lifting frame 21, the second synchronous belt 248 can drive the second discharge trough 245 to extend or retract through the clearance groove of the first discharge trough 241. When the first discharge chute 241 moves, since a fixed connection point is formed between one side of the second synchronous belt 248 on the first discharge chute 241 and the lifting frame 21, the second synchronous belt 248 rotates around the fixed block as a fulcrum. For example, when the first discharge is extended from below the discharge port, the second discharge chute 245 can also extend relative to the first discharge chute 241; when the first discharge chute 241 is retracted, the second discharge chute 245 can also retract relative to the first discharge chute 241. In this way, the first discharge chute 241 and the second discharge chute 245 can form a two-stage extension and retraction on the bottom side of the hopper 22. When extended, it can extend to a longer length, and when retracted, it can be further retracted to the bottom side of the hopper 22.

[0026] To facilitate better material discharge from the hopper 22, in this embodiment, the bottom surface of the hopper 22 is inclined downwards along the direction close to the discharge port. This inclined bottom surface of the hopper 22 helps guide the material within it to the discharge port, allowing for more complete material removal and improving material discharge efficiency.

[0027] Furthermore, the top two sides of the hopper 22 are inclined downwards along the direction close to the center of the hopper 22. The hopper 22 forms a space that gradually increases in size at the top, which facilitates the entry of materials into the hopper 22. After the materials enter the hopper 22, the materials gather from the top of the hopper 22 towards the center, improving the flowability of the materials in the hopper 22 and allowing the materials in the hopper 22 to be discharged more effectively.

[0028] The baffle plate 23 can close or open the discharge port by moving in a straight line towards or away from it, or by rotating it. Specifically, the top side of the baffle plate 23 is hinged to the outside of the hopper 22. A rotary drive is provided on the lifting frame 21, which drives the baffle plate 23. The rotary drive can rotate the baffle plate 23 upward to open the discharge port or rotate it downward to close the discharge port. When transferring material into the hopper 22, the rotary drive causes the baffle plate 23 to rotate downward to close the discharge port, thereby preventing material from being discharged from the hopper 22. When it is necessary to discharge material from the hopper 22, the rotary drive causes the baffle plate 23 to rotate upward to open the discharge port, at which time the material can be discharged from the discharge port.

[0029] In some embodiments, a vibrator 25 is provided on the outside of the hopper 22. When it is necessary to discharge the material in the hopper 22, the vibrator 25 operates, causing the hopper 22 to vibrate, which can improve the efficiency of material discharge from the hopper 22 and effectively reduce the phenomenon of material accumulation inside the hopper 22.

[0030] Furthermore, a material detection sensor 26 is installed on the lifting frame 21. The detection direction of the material detection sensor 26 is towards the discharge port. The material detection sensor 26 can be an infrared sensor, an image recognition device, etc. The material detection sensor 26 can detect whether there is still material being discharged at the discharge port, which helps to ensure that the material in the hopper 22 is completely discharged, thereby improving the accuracy of the amount of material fed into the target equipment.

[0031] A drive structure is provided on the vehicle body 1 to move the lifting frame 21 up and down. Specifically, as follows: Figure 3As shown, a vertical frame 11 is provided on the top side of the vehicle body 1. A lifting drive source is provided inside the vertical frame 11. A lifting frame 21 is slidably connected to the vertical frame 11. The lifting drive source drives the lifting frame 21, which can move up and down. The lifting drive source provides a driving force to the lifting frame 21 in the vertical direction. When it is necessary to add material into the hopper 22, the lifting drive source drives the lifting frame 21 to move downward on the vertical frame 11, thereby lowering the height of the hopper 22 and facilitating the addition of material into the hopper 22. When it is necessary to pour the material in the hopper 22 into the target equipment, the lifting drive source drives the lifting frame 21 to move upward, thereby raising the hopper 22 and facilitating the pouring of the material in the hopper 22 into the target equipment through the discharge port.

[0032] The lifting drive source can be a cylinder, hydraulic cylinder, or other similar drive source. However, when a large driving stroke is required, it occupies a large space. Therefore, in this embodiment, the lifting drive source includes a second motor 121 and a fifth synchronous pulley 122 mounted on the vertical frame 11. Two fifth synchronous pulleys 122 are spaced apart in the vertical direction. The second motor 121 drives and connects to either of the fifth synchronous pulleys 122. A third synchronous belt is connected between the two fifth synchronous pulleys 122. The lifting frame 21 is connected to the third synchronous belt. When the second motor 121 drives the fifth synchronous pulley 122 to rotate, the third synchronous belt can drive the lifting frame 21 to slide up or down. The second motor 121 can provide rotational driving force to the fifth synchronous pulley 122. By driving the fifth synchronous pulley 122 to rotate, the third synchronous belt is driven to rotate between the two fifth synchronous pulleys 122. At this time, the third synchronous belt can drive the lifting frame 21 to slide up or down, thereby adjusting the height of the hopper 22. This allows for a significant adjustment of the hopper 22's position in the vertical direction and makes the overall structure more compact.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
