Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling, and in particular to a composite AGV logistics handling device. Background Technology
[0002] Composite AGVs are intelligent logistics devices that integrate multiple functions and technologies for automated handling, storage, sorting, and distribution. Unlike traditional single-function AGVs, composite AGVs can flexibly perform various logistics operations according to actual needs, adapting to complex working environments and task requirements.
[0003] When using an AGV (Automated Guided Vehicle) to handle logistics goods or shelves, the process begins by first activating a hydraulic cylinder to raise the forks on the sliding frame to a certain height, based on the height and position of the shelf. Then, the internal drive mechanism of the AGV moves the sliding frame and forks to one end. This drive mechanism can be an electric telescopic rod or a motor-driven screw, so there are no fixed limitations. Next, one end of the forks is inserted into the bottom of the shelf, and the hydraulic cylinder is activated again to raise the forks and lift the shelf. Finally, the internal drive mechanism of the AGV resets the sliding frame and forks, placing the shelf and the goods on top onto the AGV. The AGV then begins its transport operation. Because one end of the forks is designed for easy loading and unloading, and the side away from the sliding frame lacks any blocking or limiting measures, the shelf or goods are prone to sliding due to inertia during transport, potentially even sliding off the forks' surface. This can damage the goods and, in severe cases, cause transport accidents, disrupting normal logistics operations. Utility Model Content
[0004] The technical problem this utility model aims to solve is that, because one end of the fork is designed for easy loading and unloading, and the side away from the sliding frame lacks any blocking or limiting measures, the logistics rack or goods are prone to sliding due to inertia during handling, or even sliding off the surface of the fork, resulting in damage to the goods. In severe cases, it can even cause handling accidents and affect the normal operation of logistics.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a composite AGV logistics handling device, including an AGV logistics handling machine. A sliding frame is slidably installed on the inner wall of the AGV logistics handling machine, and a fork is slidably installed on the inner wall of the sliding frame. One end of the fork is inserted into the inner wall of the AGV logistics handling machine. A hydraulic rod is fixedly installed on one side of the inner wall of the sliding frame, and the output end of the hydraulic rod is fixedly installed on one side of the fork. A limit device is provided on one side of the AGV logistics handling machine, on the side of the fork away from the sliding frame. The limit device can press the limit frame and auxiliary mechanism down from the inner wall of the AGV logistics handling machine through the movement of the fork to facilitate loading, or lift it up to limit and block the logistics rack or goods being handled, thereby achieving a protective effect.
[0006] The aforementioned components achieve the following effect: When using an AGV (Automated Guided Vehicle) to handle logistics goods or shelves, based on the shelf's position, the AGV first activates its internal drive mechanism to slide the sliding frame and fork to one end. This drive mechanism can be an electric telescopic rod or a motor-driven lead screw, so no fixed limitation is made. At this time, one end of the fork presses and retracts the limiting device onto one side of the AGV, facilitating loading. Then, one end of the fork is inserted into the bottom of the shelf. Next, the AGV's internal drive mechanism is activated to reset the sliding frame and fork, placing the shelf and the goods on top onto the AGV. After the fork resets, it releases the pressure on the limiting device, causing the limiting device to reset and allowing the loaded goods to be handled properly. One side of the item is limited and blocked to prevent it from slipping and falling due to inertia during transport, thus improving stability, preventing damage, reducing accidents, and avoiding disruption to logistics operations. The AGV is then started for transport. When the item is moved to the designated location, the internal drive mechanism moves the sliding frame and forks to one end, pushing the item or shelf down. Alternatively, depending on the required height, the hydraulic cylinder can be activated to raise the forks on the sliding frame to a certain height before the internal drive mechanism moves the sliding frame and forks to one end, pushing the item or shelf down.
[0007] Preferably, the limiting device includes two abutment blocks, one side of which is fixedly installed on both sides of the fork and slidably installed in the inner wall of the AGV logistics transporter, the inner wall of the AGV logistics transporter having sliding holes; a limiting frame, the two ends of which are slidably installed in the inner walls of the two sliding holes, and one side abutting against one side of the abutment block; several springs, the two ends of which are fixedly installed on one side of the sliding hole and one side of the limiting frame; and an auxiliary mechanism, the auxiliary mechanism being disposed in the inner wall of one end of the limiting frame, so that the limiting frame can be retracted when the fork is pushed out from the inner wall of the AGV logistics transporter for loading.
[0008] The aforementioned components achieve the following effects: By setting a limiting device, when the drive mechanism inside the AGV logistics handling machine is activated, driving the sliding frame and fork to move to one end to load logistics goods, the movement of the fork to one end will cause the abutment block to move to one end, pressing one end of the limiting frame downwards, causing the spring to contract. The other end of the fork will then abut against the auxiliary mechanism, causing it to rotate to a certain angle and then pass over to facilitate the lifting and loading operation of the logistics rack or goods. When the fork and sliding frame return to their original positions, one side of the abutment block will move away from one side of the limiting frame, and at the same time, one end of the fork will release its abutment against the auxiliary mechanism, causing the auxiliary mechanism to return to its original position. Simultaneously, the spring will drive the limiting frame to return to its original position, limiting and blocking the side of the goods loaded on the AGV logistics handling machine away from the sliding frame. This prevents the goods from slipping and falling due to inertia during the handling process, improving the stability during handling, avoiding damage to the goods during handling, reducing the occurrence of handling accidents, and avoiding affecting the normal operation of logistics.
[0009] Preferably, the limiting device further includes a plurality of support rods, wherein the outer surface of the support rods is installed through the inner wall of the spring and the inner wall of the limiting frame, and both ends are respectively fixedly installed on both sides of the inner wall of the sliding hole.
[0010] The effect achieved by the above components is that by setting up support rods, the inner wall of the spring limit frame can be supported and reinforced, making it more stable during use and less prone to shaking and damage.
[0011] Preferably, a plurality of round rollers are rotatably mounted on one side of the abutment block, wherein the round rollers are arranged on the side of the abutment block near the limiting frame.
[0012] The effect achieved by the above components is that by setting the round roller, the contact friction between the abutment block and the limit frame can be reduced, making it easier to push the limit frame.
[0013] Preferably, a plurality of reinforcing rods are fixedly installed on one side of the limiting frame, wherein the plurality of reinforcing rods are arranged at equal intervals.
[0014] The effect achieved by the above components is that by setting up reinforcing rods, the strength of one end of the limiting frame can be increased, thereby improving the limiting effect.
[0015] Preferably, the auxiliary mechanism includes a limiting plate and two round shafts, wherein one end of the round shaft is fixedly installed on one side of the limiting plate, and the other end is installed through one side of the inner wall of one end of the limiting frame; two torsion springs, wherein the inner wall of the torsion spring is sleeved on the outer surface of the round shaft, and both ends are fixedly installed on one side of the round shaft and one side of the limiting frame, respectively.
[0016] The effect achieved by the above components is as follows: By setting an auxiliary mechanism, when the fork moves to one end, it drives the abutment block to move to one end and presses the end of the limiting frame downward, the end of the fork will also abut against one side of the limiting plate, causing it to rotate on the limiting frame around the circular axis, causing the torsion spring to deform, until the end of the fork passes over one side of the limiting plate, thus facilitating the loading of materials onto the logistics rack. When the fork returns to its original position, the torsion spring will drive the limiting plate to return to its original position, abutting against and blocking one side of the logistics rack or goods, thus limiting its movement and achieving the effect of preventing slippage. The auxiliary limiting device performs storage and limiting treatment.
[0017] Preferably, a bearing is fixedly installed on the outer surface of the circular shaft, the bearing is disposed in the inner wall of the torsion spring, and the outer ring is fixedly installed on one side of the limiting frame.
[0018] The effect achieved by the above components is that by setting torsion springs, the rotational wear between the round shaft and the limit frame can be reduced, making the round shaft easier to rotate and increasing its service life.
[0019] Preferably, a protective block is fixedly installed on one side of the limiting plate, and the protective block is made of rubber.
[0020] The effect achieved by the above components is that by setting up protective blocks, the contact friction between one side of the limiting plate and the object can be increased, making it more secure when it is limited.
[0021] The beneficial effects of this utility model are:
[0022] By setting a limiting device, when the drive mechanism inside the AGV logistics handling machine is activated, driving the sliding frame and fork to move to one end to load logistics goods, the movement of the fork to one end will cause the abutment block to move to one end, pressing one end of the limiting frame downwards, causing the spring to contract. The other end of the fork will then abut against the auxiliary mechanism, causing it to rotate to a certain angle and then pass over to facilitate the lifting and loading operation of the logistics rack or goods. When the fork and sliding frame return to their original positions, one side of the abutment block will move away from one side of the limiting frame, and at the same time, one end of the fork will release its abutment against the auxiliary mechanism, causing the auxiliary mechanism to return to its original position. Simultaneously, the spring will drive the limiting frame to return to its original position, limiting and blocking the side of the goods loaded on the AGV logistics handling machine away from the sliding frame. This prevents the goods from slipping and falling off due to inertia during the handling process, improving the stability of the handling, avoiding damage to the goods during handling, reducing the occurrence of handling accidents, and avoiding affecting the normal operation of logistics.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0033] Figure 1-6The composite AGV logistics handling device shown includes an AGV logistics handling machine 1. A sliding frame 3 is slidably installed on the inner wall of the AGV logistics handling machine 1, and a fork 5 is slidably installed on the inner wall of the sliding frame 3. One end of the fork 5 is inserted into the inner wall of the AGV logistics handling machine 1. A hydraulic rod is fixedly installed on one side of the inner wall of the sliding frame 3, and the output end of the hydraulic rod is fixedly installed on one side of the fork 5. A limit device 2 is provided on one side of the AGV logistics handling machine 1, on the side of the fork 5 away from the sliding frame 3. The limit device 2 can press the limit frame 23 and the auxiliary mechanism 25 out of the inner wall of the AGV logistics handling machine 1 through the movement of the fork 5 to facilitate loading, or lift it to limit and block the logistics rack or goods being transported, thereby achieving a protective effect. When using the AGV logistics handling machine 1 to handle logistics goods or logistics racks, based on the position of the logistics rack, the internal drive mechanism of the AGV logistics handling machine 1 is first activated to drive the sliding frame 3 and fork 5 to slide to one end. This drive mechanism can be driven by an electric telescopic rod or a motor-driven lead screw, so no fixed limitation is made. At this time, one end of the fork 5 will press and retract the limiting device 2 onto one side of the AGV logistics handling machine 1, facilitating loading. Then, one end of the fork 5 is inserted into the bottom of the logistics rack. Next, the internal drive mechanism of the AGV logistics handling machine 1 is activated to reset the sliding frame 3 and fork 5, placing the logistics rack and the goods on top onto the AGV logistics handling machine 1. After the fork 5 resets, it releases the pressure on the limiting device 2, causing the limiting device 2 to reset, allowing the loaded goods to be moved to one side. The AGV (Automated Guided Vehicle) is equipped with limit switches to prevent it from slipping and falling due to inertia during transport, thus improving stability, preventing damage to goods, reducing accidents, and ensuring smooth logistics operations. The AGV is then started for transport. When the goods are moved to the designated location, the internal drive mechanism of the AGV moves the sliding frame 3 and fork 5 to one end, pushing the transported goods or shelves down. Alternatively, depending on the required height, the hydraulic cylinder 4 can be activated to raise the fork 5 on the sliding frame 3 to a certain height before the internal drive mechanism of the AGV moves the sliding frame 3 and fork 5 to one end, pushing the transported goods or shelves down.
[0034] Figure 1-6The limiting device 2 shown includes two abutment blocks 22, one side of which is fixedly installed on both sides of the fork 5 and slidably installed in the inner wall of the AGV logistics transport machine 1. The inner wall of the AGV logistics transport machine 1 has sliding holes 21. A limiting frame 23 is provided, with both ends of the limiting frame 23 slidably installed in the inner walls of the two sliding holes 21, and one side abutting against one side of the abutment block 22. Several springs 24 are provided, with both ends of the springs 24 fixedly installed on one side of the sliding hole 21 and one side of the limiting frame 23. An auxiliary mechanism 25 is provided in the inner wall of one end of the limiting frame 23, so that the limiting frame 23 can be stored when the fork 5 is pushed out from the inner wall of the AGV logistics transport machine 1 for loading. By setting the limiting device 2, when the drive mechanism inside the AGV logistics handling machine 1 is started, driving the sliding frame 3 and the fork 5 to move to one end to load logistics goods, the movement of the fork 5 to one end will drive the abutment block 22 to move to one end, pressing one end of the limiting frame 23 downward, causing the spring 24 to contract. The other end of the fork 5 will abut against the auxiliary mechanism 25, causing it to rotate to a certain angle, and then pass over to facilitate the lifting and loading operation of the logistics rack or goods. When the fork 5 and the sliding frame 3 return to their original positions, the abutment block 22... One side of the fork 2 will move away from the side of the limit frame 23, and at the same time, one end of the fork 5 will release its contact with the auxiliary mechanism 25. The auxiliary mechanism 25 will reset, and at the same time, the spring 24 will drive the limit frame 23 to reset, thus limiting and blocking the side of the goods on the AGV logistics handling machine 1 away from the sliding frame 3. This prevents the goods from slipping and falling off due to inertia during the handling process, improves the stability of the handling, avoids damage to the goods during the handling process, reduces the occurrence of handling accidents, and avoids affecting the normal operation of logistics.
[0035] Figure 1-6 The limiting device 2 shown also includes several support rods 26, the outer surfaces of which are installed through the inner walls of the spring 24 and the limiting frame 23, and both ends are fixedly installed on the inner walls of the sliding hole 21. By setting the support rods 26, the inner walls of the limiting frame 23 of the spring 24 can be supported and reinforced, making it more stable during use and less prone to shaking and damage. Several rollers 27 are rotatably installed on one side of the abutment block 22, with the rollers 27 located on the side of the abutment block 22 closest to the limiting frame 23. By setting the rollers 27, the abutment friction between the abutment block 22 and the limiting frame 23 can be reduced, facilitating the pushing of the limiting frame 23. Several reinforcing rods 28 are fixedly installed on one side of the limiting frame 23, with the reinforcing rods 28 arranged at equal intervals. By setting the reinforcing rods 28, the strength of one end of the limiting frame 23 can be increased, improving the limiting effect.
[0036] Figure 1-6The auxiliary mechanism 25 shown includes a limiting plate 251 and two round shafts 252, wherein one end of the round shaft 252 is fixedly installed on one side of the limiting plate 251, and the other end is installed through and installed on one side of the inner wall of one end of the limiting frame 23; two torsion springs 253, wherein the inner wall of the torsion spring 253 is sleeved on the outer surface of the round shaft 252, and both ends are fixedly installed on one side of the round shaft 252 and one side of the limiting frame 23, respectively. By setting the auxiliary mechanism 25, when the fork 5 moves to one end, it drives the abutment block 22 to move to one end and presses the end of the limiting frame 23 downward. At the same time, the end of the fork 5 will also abut against one side of the limiting plate 251, causing it to rotate on the limiting frame 23 with the circular shaft 252 as the center. This causes the torsion spring 253 to deform until the end of the fork 5 passes over one side of the limiting plate 251, which facilitates the loading of materials onto the logistics rack. When the fork 5 returns to its original position, the torsion spring 253 will drive the limiting plate 251 to return to its original position and abut against one side of the logistics rack or goods to limit its movement, thereby achieving the effect of preventing slippage. The auxiliary limiting device 2 performs storage and limiting treatment.
[0037] Figure 1-6 A bearing 254 is fixedly mounted on the outer surface of the circular shaft 252. The bearing 254 is disposed in the inner wall of the torsion spring 253, and its outer ring is fixedly mounted on one side of the limiting frame 23. By setting the torsion spring 253, the rotational wear between the circular shaft 252 and the limiting frame 23 can be reduced, facilitating the rotation of the circular shaft 252 and improving its service life. A protective block 255, made of rubber, is fixedly mounted on one side of the limiting plate 251. By setting the protective block 255, the contact friction between one side of the limiting plate 251 and the object can be increased, making it more secure when limiting.
[0038] Working Principle: When using the AGV logistics handling machine 1 to handle logistics goods or logistics racks, based on the position of the logistics rack, the internal drive mechanism of the AGV logistics handling machine 1 is first activated, causing the sliding frame 3 and fork 5 to slide to one end. This drive mechanism can be driven by an electric telescopic rod or a motor-driven lead screw, so no fixed limitation is made. The movement of the fork 5 to one end causes the abutment block 22 to move to one end, pressing one end of the limiting frame 23 downwards, causing the spring 24 to contract. One end of the fork 5 will then abut against the limiting frame 23. On one side of the positioning plate 251, it is rotated around the circular axis 252 on the limiting frame 23, causing the torsion spring 253 to deform until one end of the fork 5 passes over one side of the limiting plate 251. Then, one end of the fork 5 is inserted into the bottom of the logistics rack. Then, the drive mechanism inside the AGV logistics handling machine 1 is activated to reset the sliding frame 3 and the fork 5, placing the logistics rack and the goods on it onto the AGV logistics handling machine 1. After the fork 5 and the sliding frame 3 are reset, one side of the abutment block 22 will move away from one side of the limiting frame 23, and the other side will move away from the other side of the limiting frame 23. When one end is moved away from one side of the limiting plate 251, the torsion spring 253 will drive the limiting plate 251 to reset, and the spring 24 will drive the limiting frame 23 to reset. The side of the goods loaded on the AGV logistics handling machine 1 away from the sliding frame 3 will be blocked by the limiting plate 251, so that it is not easy for the goods to slip off and fall off due to inertia during the handling process, thereby improving the stability of the handling, avoiding damage to the goods during the handling process, reducing the occurrence of handling accidents, and avoiding affecting the normal operation of logistics. Then, the AGV logistics handling machine 1 will be started for handling. When the goods are moved to the designated position, the drive mechanism inside the AGV logistics handling machine 1 can be started to drive the sliding frame 3 and the fork 5 to move to one end, pushing out the goods or logistics rack and placing them down. Alternatively, depending on the required placement height, the hydraulic cylinder 4 can be started first to drive the fork 5 to rise and slide on the sliding frame 3 to a certain height, and then the drive mechanism inside the AGV logistics handling machine 1 can be started to drive the sliding frame 3 and the fork 5 to move to one end, pushing out the goods or logistics rack and placing them down.
