Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, and in particular relates to a transfer mechanism and an automatic connecting conveying system. Background Technology

[0002] With the development of intelligent logistics, the use of AGVs to replace manual forklifts is gradually becoming a trend. Pallet AGVs have a small turning radius, saving space in factory operations, and do not require pallet racks when placing palletized goods, making them very popular in the market. However, the low chassis of pallet AGVs, while enabling them to complete transfers, prevents them from directly connecting goods to the conveyor line.

[0003] To address this issue, some researchers have developed specialized transfer robots, such as the "Fork-Holding Pallet Transfer Robot" disclosed in Chinese Patent 202321612440.3. This device is designed for AGV vehicles and can automatically complete the handover of goods between the conveyor line and the AGV vehicle.

[0004] However, to avoid interference at the end of the conveyor line, the equipment needs to reciprocate along the conveying direction during operation. This requires the installation of two traveling mechanisms, as well as related synchronization mechanisms, control units, and control methods, increasing both manufacturing and operating costs.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0011] According to the transfer mechanism of this utility model, the ferry conveying assembly includes a ferry chain disposed on a chain frame plate and multiple sprockets that are cyclically wound around the ferry chains, one of which is a drive sprocket. A drive shaft is provided between the two chain frames, and the two ends of the drive shaft are respectively connected to the drive sprockets of the corresponding side of the transfer conveyor assembly; the transfer motor is driven by the drive shaft.

[0020] As one embodiment, the drive assembly of this utility model includes a reciprocating motor 16, which is connected to a drive gear 161; a rack 162, which is parallel to the conveying direction and meshes with the drive gear 161, is fixed below the moving frame 1; the moving frame 1 is driven to reciprocate linearly by the forward or reverse rotation of the reciprocating motor 16.

The telescopic rod's extension and retraction movement drives the movable frame 1 to perform reciprocating linear movement. Optionally, the hydraulic cylinder can also be replaced by an electric cylinder or a pneumatic cylinder.

[0022] As one embodiment, the ferry conveyor assembly includes a ferry chain 13 disposed on the chain frame plate 12 and a plurality of sprockets circumferentially wound around the ferry chains 13, one of which is a drive sprocket; A drive shaft 141 is provided between the two chain-mounted frames 12, and the two ends of the drive shaft 141 are respectively connected to the drive sprockets of the corresponding transfer conveyor components on one side; the transfer motor 14 is driven by the drive shaft 141.

[0024] Optionally, those skilled in the art can use the structure disclosed in Chinese Patent 2023107500182 to realize the ferry transfer of goods 51 in this utility model.

[0025] See Figure 3This utility model also provides an automatic connecting and conveying system for connecting and conveying goods 51 placed on a pallet 5; including The aforementioned transfer mechanism; Conveyor line 2 is located at the rear end of the transfer mechanism and is connected to the transfer mechanism; The docking robot 3 is located at the front end of the transfer mechanism and has two forks for inserting and holding pallets 5 and for lifting and lowering, as well as two support columns. AGV vehicle 4 can enter and exit between the two support columns of the shuttle robot 3 and can travel under the forks; The front end of the transfer mechanism's mobile frame 1 can move along the conveying direction to the space between the forks of the connecting robot 3 and the AGV vehicle 4; the clearance space formed between the two front legs 17 of the mobile frame 1 can accommodate the AGV vehicle 4, so that the AGV vehicle 4 and the forks of the connecting robot 3 are located on the upper and lower sides of the mobile frame 1 respectively.

[0026] Loading goods onto conveyor line 2: The AGV 4 delivers the goods 51 placed on the pallet 5 to the area under the forks. Then, the two forks of the connecting robot 3 descend and open, clamping the pallet 5 and goods 51 before rising. Next, the moving frame 1 of the transfer mechanism moves forward, its front end positioned between the forks and the AGV 4. Then, the two forks descend, placing the pallet 5 and goods 51 onto the moving frame 1.

[0027] The transfer mechanism retracts its mobile frame 1, and the two transfer components move to deliver the pallet 5 and the goods 51 to the conveyor line 2, where the transfer is completed.

Afterward, the moving frame 1 of the transfer mechanism retracts, and the forks of the transfer robot 3 descend to place the pallet 5 and the goods 51 onto the AGV vehicle 4, whereupon the transfer is completed by the AGV vehicle 4.

[0030] Those skilled in the art may choose a suitable, well-known connecting robot 3, such as the robot disclosed in Chinese Patent 202321612440.3 or 202321612432.9.

[0031] This invention utilizes a transfer mechanism to transfer goods between the conveyor line 2 and the connecting robot 3. The connecting robot 3 only needs to perform lifting and clamping actions to complete the transfer of goods 51 between the AGV vehicle 4 and the conveyor line 2. The connecting robot 3 does not need to move along the conveying direction during operation, thus simplifying its structure and eliminating the need for a walking mechanism, synchronization mechanism, control unit, and control methods. This reduces the cost of the connecting robot 3 and also simplifies the control of the transfer process.

[0032] As one embodiment, the conveyor line 2 of this utility model can be a conveyor belt type conveyor line or a conveyor roller type conveyor line.

[0033] See Figure 4 As one embodiment, the conveyor line 2 of this utility model is a chain conveyor line, including two support frames 22, each support frame 22 is equipped with a conveyor chain 23; it also includes a conveyor motor 21 that drives the two conveyor chains 23 to move synchronously.

[0036] In summary, this invention provides a transfer mechanism that uses a movable frame capable of reciprocating along the conveying direction, with two transfer components mounted on the frame, to complete the transfer of pallets and goods. This invention also provides an automated shuttle conveying system that uses the transfer mechanism to transfer goods between the conveyor line and the shuttle robot. The shuttle robot only needs to perform lifting and clamping actions to complete the transfer of goods between the AGV and the conveyor line. The shuttle robot does not need to move along the conveying direction during its operation, thus simplifying its structure and eliminating the need for a walking mechanism, related synchronization mechanisms, control units, and control methods. This reduces the cost of the shuttle robot and also simplifies the control complexity of the shuttle conveying process.
