Description

Technical Field

[0001] This invention relates to the field of material handling technology, and more specifically, to an automated transport trolley with multiple containers on one vehicle and its transport method. Background Technology

[0002] The emergence of material handling trolleys stems from the urgent need in industrial production and logistics to improve efficiency, ensure safety, and optimize costs. With the large-scale development of global manufacturing and the explosive growth of e-commerce, traditional manual handling methods have gradually revealed problems such as excessive labor intensity, large efficiency fluctuations, high error rates, and numerous safety hazards. Particularly in warehousing logistics, automobile manufacturing, and electronic assembly scenarios, the high-frequency, heavy-load material transportation demands and the continuously rising labor costs create a contradiction, making traditional manual material handling increasingly inadequate and unable to keep pace with fast-paced market operations. Chinese utility model patent CN222389523U discloses a forklift for material handling, specifically including a forklift body, a slide rail, and a handling unit. The forklift body is slidably connected to the slide rail, and the handling unit is raised and lowered on the forklift body. The forklift body controls the operation of the handling unit, which is used for placing materials. However, this type of handling device requires high operational skills, necessitates professional operation, and is relatively inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide an automated guided vehicle (AGV) for transporting multiple containers simultaneously and its transport method. This invention has low operational requirements, eliminates the need for forklifts and specialized personnel, saving manpower and facilitating transport.

[0004] The technical solution of the present invention: an automated guided vehicle (AGV) for transporting multiple cabinets, comprising a vehicle body, characterized in that the vehicle body is connected to a platform, the platform having multiple placement positions for placing transport cabinets; a rotating slide rod is rotatably connected to one side of the platform, a telescopic arm is slidably connected to the rotating slide rod, and an adsorption gripper is rotatably connected to the upper end of the telescopic arm; a push rod is fixed to one end of the rotating slide rod; a hydraulic cylinder is hinged to the inner side of the platform of the vehicle body, the telescopic end of the hydraulic cylinder being hinged to the end of the push rod.

[0005] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the vehicle body is equipped with a pair of connecting frames; the rear of the hydraulic cylinder is equipped with a connecting block, which is located inside the connecting frames and is rotatably connected via a pin shaft.

[0006] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the two ends of the rotating slide rod are rotatably connected to the vehicle body via bearings; the rotating slide rod is coated with lubricating oil.

[0007] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the telescopic boom includes a sliding sleeve fitted onto a rotating slide rod and slidably connected thereto. A sleeve is fixed on the sliding sleeve, and a lifting rod is slidably disposed inside the sleeve. The suction gripper is rotatably disposed at the upper end of the lifting rod.

[0008] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the suction gripper includes a suction box body rotatably connected to the upper end of the lifting rod, and an electromagnet is provided at the bottom of the suction box body.

[0009] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the bottom sides of the adsorption box are provided with first positioning blocks.

[0010] In the aforementioned automated guided vehicle (AGV) with multiple containers, the vehicle body has multiple sets of second positioning blocks on its platform.

[0011] In the aforementioned automated guided vehicle (AGV) with multiple cabinets, the bottom of the vehicle body is equipped with multiple balance supports and hydraulic cylinders connected to the balance supports; the multiple balance supports are arranged in a triangular pattern.

[0012] The aforementioned handling method for multi-container automated guided vehicles includes loading and unloading of containers: When loading the transport container, after the trolley body reaches the designated position, the motor drives the lifting rod to rise. The sliding sleeve slides on the rotating slide rod to the designated position. Then, the hydraulic cylinder pushes the rotating rod to rotate the rotating slide rod, thereby rotating the sleeve on the rotating slide rod to align it with the loading position. Then, the lifting rod descends so that the suction gripper grabs the transport container at the loading position. The lifting rod rises, thereby lifting the transport container. Then, the hydraulic cylinder pulls back to push the rotating rod to reverse the rotation of the rotating slide rod, thereby rotating the sleeve on the rotating slide rod back. This moves the transport container from above the loading position to above the empty position of the trolley body. The rotating slide rod continues to rotate, causing the transport container to fall into the empty position. Because the suction gripper is rotatably connected to the upper end of the telescopic arm, the transport container remains vertical during the rotation of the rotating slide rod until it reaches the placement position. Then, the suction gripper releases the transport container, the sleeve returns to its original position, the lifting rod descends to reset, and the loading is completed. When unloading the transport container, after the trolley body reaches the designated position, the motor drives the lifting rod to rise. The sliding sleeve slides on the rotating slide rod to the designated position, aligning it with the transport container. Then, the lifting rod descends, allowing the suction gripper to grab the transport container. The lifting rod rises again, thus lifting the transport container. Then, the hydraulic cylinder pushes the rotating rod to rotate the rotating slide rod, which in turn rotates the sleeve on the rotating slide rod, moving the transport container from above the trolley body to above the unloading point. The rotating slide rod continues to rotate, causing the transport container to fall to the unloading point. Because the suction gripper is rotatably connected to the upper end of the lifting rod, the transport container remains vertical during the rotation of the rotating slide rod until it reaches the unloading point. Then, the suction gripper releases the transport container, and the hydraulic cylinder pulls back to push the rotating rod to reverse the rotation of the rotating slide rod. Then, the sleeve returns to its original position, the lifting rod descends to reset, and the unloading process ends.

[0013] The aforementioned method for transporting a multi-cabinet automated guided vehicle includes: setting multiple balance rods and hydraulic cylinders connected to the balance rods at the bottom of the vehicle body; after the vehicle reaches the designated position, the hydraulic cylinders are activated to release the multiple balance rods from the bottom of the vehicle body to contact the ground. A first positioning block is set on the adsorption gripper to facilitate the positioning of the adsorption gripper when the adsorption transport cabinet is used; Multiple sets of second positioning blocks are provided on the platform of the trolley body to facilitate the positioning of the transport cabinet when it is placed on the placement position of the trolley body platform.

[0014] Compared with the prior art, the present invention has the following effects: 1. The handling system of this invention includes a trolley body. A rotating slide rod is rotatably connected to one side of the trolley body's platform. A telescopic arm is slidably connected to the rotating slide rod, and an adsorption gripper is rotatably connected to the upper end of the telescopic arm. A push rod is fixed to one end of the rotating slide rod. A hydraulic cylinder is hinged to the inner side of the trolley body's platform, and the telescopic end of the hydraulic cylinder is hinged to the end of the push rod. The rotation of the rotating slide rod and the extension / retraction of the telescopic arm allow the adsorption gripper connected to the upper end of the telescopic arm to move to a designated position for operation as needed. Loading and unloading of the transport cabinet can be completed simply by manually moving the telescopic arm on the rotating slide rod to align it with the transport cabinet, without the need for forklifts or specialized personnel, saving manpower and facilitating handling. The coordination of the connecting frame, hydraulic cylinder, rotating slide rod, telescopic arm, lifting rod, adsorption gripper, and electromagnet enables multi-angle and multi-directional movement. Combined with the electromagnets in the lifting rod and adsorption gripper, it can quickly and accurately grasp and place goods, easily handling delicate handling tasks in confined spaces or complex environments. This not only improves the automation level of handling and reduces manpower input, but also reduces the risk of errors that may be caused by manual operation, ensuring the safety and integrity of goods during the handling process.

[0015] 2. The present invention features first positioning blocks on both sides of the bottom of the adsorption box; and multiple sets of second positioning blocks on the carriage body. The first positioning blocks on both sides of the bottom of the adsorption box engage with the top of the transport cabinet, and are secured by the magnetic attraction of an electromagnet, achieving precise gripping and avoiding positioning deviations caused by wear in traditional mechanical grippers. The second positioning blocks on the carriage body engage with the bottom of the transport cabinet, ensuring that the transport cabinet is vertically aligned when placed on the carriage, preventing the cabinet from sliding or tipping over during transportation and improving transportation safety. Furthermore, because this positioning structure adopts a nested design of cones and slots, it reduces hard friction between mechanical parts, extends the service life of the equipment, reduces maintenance frequency and costs, and has significant economic benefits and practical value.

[0016] 3. The trolley body of this invention has multiple downward-facing balance supports at its bottom. Each balance support is connected to a corresponding hydraulic cylinder, and the multiple balance supports are arranged in a triangle, that is, two balance supports are located on one side of the trolley body and the rotating slide, and one balance support is located on the other side. All the balance supports are controlled by independent hydraulic cylinders, and can be simultaneously lowered to the ground after reaching the designated position, forming a stable triangular support structure. Compared with traditional transport vehicles that rely solely on wheel support, this invention reduces the risk of tipping over due to center of gravity shift during transport, and is especially suitable for transporting heavy-duty or high-center-of-gravity cabinets, improving the stability and safety of transport. Besides heavy-duty and high-center-of-gravity cabinets, it also plays an important role in scenarios with extremely high stability requirements, such as the transport of medical equipment and precision instruments, reducing equipment damage caused by vibration and tilting. It not only improves the stability and safety of transport operations, but also reduces the workload of operators and increases work efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example: A handling method using an automated guided vehicle (AGV) with multiple containers per vehicle, applicable to handling systems, configured as follows: Figure 1-5As shown, the device includes a trolley body 101, which is connected to a platform 1011. The platform 1011 has multiple placement positions 1012 for placing the transport cabinet 301. The platform 1011 of the trolley body 101 is provided with a pair of connecting frames 104. A hydraulic cylinder 102 is connected to the connecting frame 104. A connecting block 1041 is provided at the tail of the hydraulic cylinder 102. The connecting block 1041 is located inside the connecting frame 104 and is rotatably connected via a pin. The connecting frame 104 is located near the front of the platform 1011, saving space on the platform 1011 of the trolley body 101 and leaving space for the placement positions 1012 at the rear of the platform 1011. A rotating slide rod 202 is rotatably connected to one side of the placement position 1012 on the platform 1011 of the trolley body 101. The two ends of the rotating slide rod 202 are rotatably connected to the trolley body 101 via bearings. A telescopic arm 203 is slidably connected to the rotating slide rod 202. The rotation of the rotating slide rod 202 and the extension and retraction of the telescopic arm 203 allow the suction gripper 205 connected to the upper end of the telescopic arm 203 to be moved to the designated position for operation as needed. The telescopic arm 203 can be manually moved on the rotating slide rod 202 to align with the handling cabinet 301, and the loading and unloading of the handling cabinet 301 can be completed without the need for a forklift or specially hired professionals. This not only saves manpower but also facilitates handling.

[0023] like Figure 2 As shown, a second positioning block 105 is provided on the placement position 1012 of the carriage body 101's platform 1011. The multiple sets of second positioning blocks 105 facilitate positioning of the transport cabinet 301 when placed on the platform 1011's placement position 1012. The second positioning blocks 105 on the carriage body 101's platform 1011 engage with the bottom of the transport cabinet 301, ensuring that the transport cabinet 301 is vertically aligned when placed on the platform 1011's placement position 1012, preventing the cabinet from sliding or tipping over during transportation and improving transportation safety. Furthermore, because this positioning structure uses a conical and slotted nested design, it reduces hard friction between mechanical parts, extends the equipment's service life, and reduces maintenance frequency and costs, resulting in significant economic benefits and practical value.

[0024] like Figure 3-4As shown: A hydraulic cylinder 102 is hinged to the inner side of the car body 101's plate 1011. The hydraulic cylinder has stable and reliable power output, fast response speed, simple structure, and low maintenance cost. A push rod 207 is fixed to one end of the rotating slide rod 202; the push rod 207 is plate-shaped, with one end larger and hollow, sleeved on the top of the rotating slide rod 202, and the other end smaller, hinged to the telescopic end of the hydraulic cylinder 102; the rotating slide rod 202 is slightly shorter than the length of the car body 101, and both ends of the rotating slide rod 202 are fixed to one side of the car body 101 via bearings. The bearing connection not only provides stable support and ensures rotational accuracy but also reduces friction and energy consumption, improving efficiency. The rotating slide rod 202 is a smooth cylinder, and the rod body is coated with lubricating oil. Applying lubricating oil not only reduces friction and wear and protects components, but also reduces energy consumption and improves operating efficiency. The telescopic boom 203 is an L-shaped hollow tube. The telescopic boom 203 includes a sliding sleeve 209 that is sleeved on and slidably connected to the rotating slide rod 202. A sleeve 210 is fixed on the sliding sleeve 209, and a lifting rod 204 is slidably arranged inside the sleeve 210. A cylinder or hydraulic cylinder is provided inside the sleeve 210 to provide lifting power for the lifting rod 204 inside the sleeve 210. An adsorption gripper 205 is rotatably connected to the upper end of the telescopic boom 203. The adsorption gripper 205 is rotatably arranged at the upper end of the lifting rod 204. The adsorption gripper 205 includes an adsorption box 2051 that is rotatably connected to the upper end of the lifting rod 204. The rotatable connection is achieved by a rotating shaft 211 provided at the upper end of the lifting rod 204. A through hole 212 is provided on the adsorption box 2051 and a bearing is provided to cooperate with the rotating shaft 211. An electromagnet 206 is installed at the bottom of the adsorption box 2051; first positioning blocks 214 are installed on both sides of the bottom of the adsorption box 2051 to facilitate the positioning of the adsorption gripper 205 when adsorbing the transport cabinet 301. The first positioning blocks 214 on both sides of the bottom of the adsorption box 2051 fit into the top of the transport cabinet 301, and combined with the magnetic attraction of the electromagnet 206, precise gripping is achieved, avoiding the positioning deviation caused by wear of traditional mechanical grippers. The use of a conical and slotted nested design reduces hard friction between mechanical parts, extends the service life of the equipment, reduces maintenance frequency and cost, and has significant economic benefits and practical value. The hydraulic cylinder 102, rotating slide bar 202, telescopic boom 203, lifting rod 204, suction gripper 205, and electromagnet 206 work together to achieve multi-angle and multi-directional movement. Combined with the electromagnet 206 within the lifting rod 204 and suction gripper 205, goods can be quickly and accurately grasped and placed. This allows for easy handling of delicate transport tasks, whether operating in confined spaces or in complex environments. It not only improves the automation level of transport and reduces manpower input but also lowers the risk of errors that may arise from manual operation, ensuring the safety and integrity of goods during transport.

[0025] like Figure 5As shown: The bottom of the trolley body 101 is equipped with multiple balance support rods 103 and hydraulic cylinders 106 connected to the balance support rods 103. The multiple balance support rods 103 are arranged in a triangle, that is, two balance support rods 103 are located on one side of the bottom of the trolley body 101 and the rotating slide rod 202, and one balance support rod 103 is located on the other side. After the trolley reaches the designated position, the hydraulic cylinder 106 operates, and upon reaching the designated position, the multiple balance support rods 103 are simultaneously lowered from the bottom of the trolley body 101 to contact the ground, forming a stable triangular support structure. Compared with traditional pallet trucks that rely solely on wheel support, this invention reduces the risk of tipping over due to center of gravity shift during transport, and is especially suitable for transporting heavy-duty or high-center-of-gravity cabinets, improving the stability and safety of transport. Besides heavy-duty and high-center-of-gravity cabinets, it also plays an important role in scenarios with extremely high stability requirements, such as the transport of medical equipment and precision instruments, reducing equipment damage caused by vibration and tilting. It not only improves the stability and safety of transport operations, but also reduces the workload of operators and increases work efficiency.

[0026] Working principle: Combining Figure 1-5 As shown, the handling method of a multi-container automated guided vehicle (AGV) includes loading and unloading of containers: When loading the transport cabinet 301, after the trolley body 101 reaches the designated position, the hydraulic cylinder 106 operates to release multiple balance support rods 103 from the bottom of the trolley body 101 to contact the ground for support. After the motor-driven lifting rod 204 rises, the sliding sleeve 209 slides on the rotating slide rod 202 to the designated position (this sliding can be manual with a linear bearing added inside the sliding sleeve 209; or it can be motor-driven with gears and racks added inside the sliding sleeve 209 and outside the rotating slide rod 202). Then, the hydraulic cylinder 102 pushes the rotating rod 207 to rotate the rotating slide rod 202, thereby rotating the sleeve 210 on the rotating slide rod 202 to align it with the loading position. Then, the lifting rod 204 descends, causing the suction gripper 205 to grab the transport cabinet 301 at the loading position. The lifting rod 204 rises, thereby raising the transport cabinet 301. Then, the hydraulic cylinder 102... The pull-back push rod 207 drives the rotating slide rod 202 to reverse, thereby causing the sleeve 210 on the rotating slide rod 202 to rotate back, which in turn moves the transport cabinet 301 from above the loading area to above the empty position of the trolley body 101 platform 1011. The rotating slide rod 202 continues to rotate, causing the transport cabinet 301 to fall into the placement position 1012 in the empty position. Because the suction gripper 205 is rotatably connected to the upper end of the telescopic arm 203, the transport cabinet 301 remains vertical during the rotation of the rotating slide rod 202 until it reaches the placement position 1012. Then the suction gripper 205 releases the transport cabinet 301, and the sleeve 210 returns to its original position. The lifting rod 204 descends and resets, ending the loading process. After loading is completed, the hydraulic cylinder 106 operates to retract multiple balance support rods 103 into the trolley body 101, and the trolley body 101 moves to the next designated position.

[0027] When unloading from the handling cabinet 301, after the trolley body 101 reaches the designated position, the hydraulic cylinder 106 operates to release multiple balance support rods 103 from the bottom of the trolley body 101 to contact the ground for support. After the motor-driven lifting rod 204 rises, the sliding sleeve 209 slides on the rotating slide rod 202 to the designated position (this sliding can be manual with a linear bearing added inside the sliding sleeve 209; or it can be motor-driven with gears and racks added inside the sliding sleeve 209 and outside the rotating slide rod 202), aligning it with the handling cabinet 301. Then, the lifting rod 204 descends, causing the suction gripper 205 to grasp the handling cabinet 301. The lifting rod 204 then rises again, thus raising the handling cabinet 301. The hydraulic cylinder 102 then pushes the rotating rod 207 to rotate the rotating slide rod 202, thereby driving the rotating slide rod 202... The upper sleeve 210 rotates, thereby moving the transport cabinet 301 from above the platform 1011 of the trolley body 101 to above the unloading point. The rotating slide bar 202 continues to rotate, causing the transport cabinet 301 to fall to the unloading point. Because the suction gripper 205 is rotatably connected to the upper end of the lifting rod 204, the transport cabinet 301 remains vertical during the rotation of the rotating slide bar 202 until it reaches the unloading point. Then, the suction gripper 205 releases the transport cabinet 301, and the hydraulic cylinder 102 pulls back to push the rotating rod 207 to drive the rotating slide bar 202 to reverse. Then, the sleeve 210 returns to its original position, and the lifting rod 204 descends to reset, ending the unloading process. After unloading, the hydraulic cylinder 106 operates to retract multiple balance supports 103 into the trolley body 101, and the trolley body 101 moves to the next designated position.

[0028] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.

Then, the hydraulic cylinder (102) drives the rotating slide rod (202) to rotate by pushing the push rod (207), thereby driving the sleeve (210) on the rotating slide rod (202) to rotate, aligning it with the loading position. Then, the lifting rod (204) descends, causing the suction gripper (205) to grab the transport container at the loading position. The lifting rod (204) rises, thereby driving the transport container to rise. Then, the hydraulic cylinder (102) pulls back the push rod (207) to drive the rotating slide rod. (202) Reverses, thereby causing the sleeve (210) on the rotating slide bar (202) to rotate back, thereby moving the transport cabinet from above the loading point to above the empty position of the trolley body (1011) platform (1011). The rotating slide bar (202) continues to rotate, causing the transport cabinet to fall into the placement position (1012) in the empty position. Since the suction gripper (205) is rotatably connected to the upper end of the telescopic arm (203), the transport cabinet remains vertical during the rotation of the rotating slide bar (202) until it reaches the placement position (1012). Then the suction gripper (205) releases the transport cabinet, and then the sleeve (210) returns to its original position. The lifting rod (204) descends and resets, ending the loading process. When unloading the transport container, after the trolley body (101) reaches the designated position, the motor drives the lifting rod (204) to rise.

The trolley body (101) moves from above the platform (1011) to above the unloading area. The rotating slide bar (202) continues to rotate, causing the transport cabinet to fall to the unloading area. Since the suction gripper (205) is rotatably connected to the upper end of the lifting rod (204), the transport cabinet remains vertical during the rotation of the rotating slide bar (202) until it reaches the unloading area. Then the suction gripper (205) releases the transport cabinet.
