Description

Technical Field

[0001] This utility model relates to the field of material handling technology, specifically to an AGV (Automated Guided Vehicle) material handling device. Background Technology

[0002] Tobacco processing is a crucial step in cigarette manufacturing. This process involves manually transporting tobacco bales from the tobacco blending warehouse to the preparation area of ​​the processing line. To reduce labor intensity, forklifts or AGVs are typically used for this purpose. However, forklifts have large blind spots, requiring on-site supervision and posing certain safety risks, and also necessitate a driver. AGVs have become widely used to address this issue, enabling point-to-point unmanned transport. However, current AGVs can only transport tobacco bales without forking them onto the vehicle itself. This means that before the AGV can transport the bales, manual labor or a forklift is still required to move them onto the AGV, which then travels along a pre-set route to its destination.

[0003] To overcome the above problems, invention patent CN116553431B discloses an AGV forklift, an active forklift handling method, and a passive forklift handling method. This device includes a forklift mechanism that can be lifted at any position within the guide groove. During use, the forklift mechanism extends forward into the pallet gap, then lifts the goods and resets, allowing the goods to fall onto the AGV. However, this device also has limitations in its movement: when handling large goods, if the forklift mechanism lifts the goods onto the vehicle body, the center of gravity is not on the vehicle body due to the large size of the goods. In this case, the AGV only supports the side of the goods, causing the goods to fall during the AGV's movement. To overcome this defect, this invention further improves upon this, thus proposing an AGV handling device. Utility Model Content

[0004] The purpose of this utility model is to provide an AGV trolley transport device that can move the middle of the goods onto the trolley when transporting large-sized goods, so that the center of gravity of the goods can fall onto the trolley, thereby preventing the goods from falling off during the transport process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An AGV (Automated Guided Vehicle) transport device includes an AGV body with three front arms. An accommodating opening is formed between two adjacent front arms, making the AGV body generally "E" shaped. At least two conveyor belt mounting slots are provided on the AGV body, extending to the front arms and a conveying device is installed in the conveyor belt mounting slots.

[0007] A lifting device is slidably disposed in the receiving opening. A drive mechanism for driving the lifting device to move linearly is disposed in the AGV body. The lifting device includes a lifting bottom groove, a lifting plate and a lifting mechanism. The lifting mechanism is disposed in the lifting bottom groove and the lifting plate is connected to the lifting mechanism so that the lifting plate can move up and down. A front extension plate is slidably disposed on the lifting plate.

[0008] A rear baffle is slidably installed at the rear of the AGV body, and a stop button is provided on the front side of the rear baffle to stop the conveying device, drive mechanism and lifting mechanism from working.

[0009] Furthermore, a screw and a horizontal guide rod are provided on the front side of the rear baffle. One end of the screw is inserted into the AGV body. An adjusting sleeve is rotatably provided on the rear side of the AGV body. The screw is threadedly connected to the adjusting sleeve. The other end of the screw is rotatably connected to the rear baffle. Horizontal guide sleeves are provided on both sides of the AGV body, and the horizontal guide rod is inserted into the horizontal guide sleeves.

[0010] Furthermore, the driving mechanism is a linear module, which is installed in the front arm located in the middle of the vehicle. Through-holes are provided on both sides of the front arm. Push rods are fixedly installed on the slider of the linear module, and the two ends of the push rods pass through the through-holes and are connected to the lifting bottom groove.

[0011] Furthermore, the lifting mechanism is a cylinder, which is fixedly installed in the middle of the lifting bottom groove, and the cylinder's push-out end is connected to the lifting plate.

[0012] Furthermore, the bottom surface of the lifting plate is provided with multiple vertical guide rods, and multiple vertical guide sleeves are provided in the lifting bottom groove, with the vertical guide rods passing through the vertical guide sleeves.

[0013] Furthermore, there are two conveying devices. The power input ends of the two conveying devices are connected by a rotating shaft, and a driven conical tooth is provided on the rotating shaft. The AGV body is also equipped with a motor, and the output end of the motor is connected to an active conical tooth. The active conical tooth and the driven conical tooth mesh with each other.

[0014] Furthermore, the bottom of the lifting trough is provided with support wheels.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention designs the AGV trolley body in an "E" shape and has a lifting device slidably installed at the receiving opening. The lifting device moves back and forth via a drive mechanism. A lifting plate is connected to the lifting device via the lifting mechanism, allowing the lifting plate to move up and down. In use, the lifting device moves forward to the bottom of the pallet, and then the lifting plate lifts the goods. During the resetting process of the lifting device, the goods fall onto the AGV trolley, thus eliminating the need for manual handling and achieving automated handling and delivery. A rear baffle is slidably installed on the rear side of the AGV trolley body, and a front baffle is slidably installed on the lifting plate. The extension plate increases the pushing area between the front and rear of the goods, preventing them from slipping due to imbalance during the pushing process. A stop button is located on the rear baffle, and a conveying device is also installed on the AGV itself. When the goods are large, the rear baffle and the front extension plate can be pulled out. Through multiple operations and resets of the lifting device, the center of the goods is gradually moved onto the AGV. When the goods touch the stop button during the movement, the lifting device stops working. This allows for the movement of larger items so that the center of gravity of the goods falls onto the AGV, thus preventing the goods from falling during handling. Attached Figure Description

[0025] refer to Figure 1-2 As shown, this utility model provides an AGV (Automated Guided Vehicle) transport device, including an AGV body 1. It should be noted that the drive control of the AGV body 1 (i.e., the movement of the vehicle, the sensing of the route position, etc.) is existing technology, and this utility model does not improve this aspect. The AGV body 1 is provided with three front arms 1a, and a receiving opening 1c is formed between two adjacent front arms 1a, so that the AGV body 1 has an overall "E" shaped structure. At least two conveyor belt mounting slots 1b are provided on the AGV body 1, and the conveyor belt mounting slots 1b extend to the front arms 1a and a conveying device 2 is installed in the conveyor belt mounting slots 1b.

[0026] Conveying device 2 is a belt conveyor, which consists of at least two rotating rollers, a conveyor belt, and a fixed trough. Its specific structure and connection are also existing technology, and will not be described in detail here. There are two conveying devices 2. (See reference...) Figure 4As shown, in order to achieve synchronous movement of the two conveying devices 2, the power input ends of the two conveying devices 2 are connected through a rotating shaft 14 and a driven bevel tooth 15 is provided on the rotating shaft 14. The rotating shaft 14 and the driven bevel tooth 15 are placed inside the AGV trolley body 1. The AGV trolley body 1 is also provided with a motor 17. The output end of the motor 17 is connected to an active bevel tooth 16, and the active bevel tooth 16 and the driven bevel tooth 15 mesh with each other.

[0027] A lifting device 3 is slidably disposed in the receiving port 1c. There are two lifting devices 3. A drive mechanism for driving the linear motion of the lifting devices 3 is provided inside the AGV body 1. (Refer to...) Figure 3 As shown, the lifting device 3 includes a lifting trough 3b, a lifting plate 3f, and a lifting mechanism. The lifting mechanism is disposed in the lifting trough 3b and the lifting plate 3f is connected to the lifting mechanism so that the lifting plate 3f can move up and down. A front extension plate 9 is slidably disposed on the lifting plate 3f. A support wheel 3e is disposed at the bottom of the lifting trough 3b to provide support for the lifting trough 3b and the goods.

[0028] In some embodiments, the driving mechanism is a linear module 11, which is disposed in the front arm 1a located in the middle of the vehicle. Through slots 1d are provided on both sides of the front arm 1a. A push rod 10 is fixedly disposed on the slider 12 of the linear module 11. The two ends of the push rod 10 pass through the through slots 1d and are connected to the lifting bottom groove 3b, so that the two lifting bottom grooves 3b can be driven to move back and forth synchronously through the linear module 11. Specifically, the push rod 10 is a square hollow rod, and the hollow part is connected to the side wall of the hollow lifting bottom groove 3b, thereby facilitating the wiring layout.

[0029] In some embodiments, the lifting mechanism is a cylinder 3a, which is fixedly installed in the middle of the lifting bottom groove 3b. The lifting plate 3f is connected to the pushing end of the cylinder 3a. Of course, the lifting mechanism can also be designed as other types of structures, such as a scissor lifting mechanism.

[0030] Furthermore, the bottom surface of the lifting plate 3f is provided with multiple vertical guide rods 3d, and multiple vertical guide sleeves 3c are provided in the lifting bottom groove 3b. The vertical guide rods 3d are inserted into the vertical guide sleeves 3c, thereby increasing the support strength of the lifting plate 3f and preventing it from tilting.

[0031] A rear baffle 6 is slidably disposed at the rear of the AGV body 1. A stop button 8 is disposed on the front side of the rear baffle 6 to stop the conveying device 2, the drive mechanism and the lifting mechanism. The position of the stop button 8 must be higher than the upper surface of the AGV body 1, at least 5 cm higher. The stop button 8 is electrically connected to the control system of the AGV body 1. The control system is used to control the operation of the motor 17, cylinder 3a and linear module 11 of the conveying device 2 and to repeatedly start the cylinder 3a and the linear module 11. Those skilled in the art can configure the specific circuit. In actual use, when the back side of the goods touches the stop button 8, the conveying device 2 stops and the lifting trough 3b and the lifting plate 3f are reset.

[0032] To facilitate adjustment of the extension distance of the rear baffle, a screw 7 and a horizontal guide rod 5 are provided on the front side of the rear baffle 6. One end of the screw 7 is inserted into the AGV body 1, and an adjusting sleeve 13 is rotatably provided on the rear side of the AGV body 1. The screw 7 is threadedly connected to the adjusting sleeve 13, and the other end of the screw 7 is rotatably connected to the rear baffle 6. This allows the extension distance of the rear baffle 6 to be adjusted by rotating the adjusting sleeve 13. Horizontal guide sleeves 4 are provided on both sides of the AGV body 1, and the horizontal guide rod 5 is inserted into the horizontal guide sleeves 4 to prevent the rear baffle 6 from rotating. In this embodiment, the horizontal guide rod 5 is also a hollow structure to facilitate line layout.

[0033] The working process of this utility model is as follows: Before operation, the extension of the rear baffle 6 and the front extension plate 9 needs to be adjusted according to the size of the goods so that the center of gravity of the goods falls on the vehicle body after they are placed on the AGV trolley body 1. During operation, when the AGV trolley body 1 travels to the side of the goods pallet, the lifting bottom groove 3b extends forward to under the pallet, and then the lifting mechanism is activated to lift the lifting plate 3f to lift the goods. Then the lifting bottom groove 3b and the lifting plate 3f reset so that the goods fall onto the vehicle body. If the back of the goods touches the stop button 8 (usually for small goods, only one reset is needed to touch the stop button 8), the loading is successful and the AGV trolley body 1 can leave. If the back of the goods does not touch the stop button 8 (usually for large goods, multiple movements are required before touching the stop button 8), the lifting bottom groove 3b and the lifting plate 3f repeatedly extend and reset, and under the action of the conveying device 2, the goods are gradually moved backward until they touch the stop button 8.

[0034] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
