[0069] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0070] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0071] There is a height difference between the height of the automatic guided vehicle after the roof is raised and the inbound conveyor line of the four-way vehicle warehouse, which makes the automatic guided vehicle unable to directly connect with the inbound conveyor line of the four-way vehicle warehouse, reducing the level of logistics automation.

[0072] Specifically, taking the latent lifting AGV as an example, the height of the latent lifting AGV after lifting is 425mm, and the height of the storage conveyor line of the four-way vehicle stereoscopic warehouse is 480mm. There is a height difference and it cannot be directly connected.

[0073] In the related art, some four-way vehicle stereoscopic warehouse docking systems are provided with a floor-standing elevator, which can lift the pallet of the automatic guided vehicle to achieve the docking of the automatic guided vehicle and the storage conveyor line of the four-way vehicle stereoscopic warehouse.

[0074] However, floor-standing elevators are expensive and take up a large space, which can easily affect the system layout and occupy the passage space of automatic guided vehicles.

[0075] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0076] According to an embodiment of the present invention, in a first aspect, a transfer device is provided, including a base frame 1, a transfer conveyor line 2 and a lifting mechanism 3.

[0077] Among them, a guide vehicle introduction part 101 and a four-way vehicle track 102 are provided on the base frame 1. The transfer conveyor line 2 is provided on the base frame 1. The guide vehicle introduction part 101 and the four-way vehicle track 102 are arranged in sequence along the conveying direction of the transfer conveyor line 2. The transfer conveyor line 2 is located above the guide vehicle introduction part 101 and the four-way vehicle track 102, and is provided on at least one side of the guide vehicle introduction part 101 and the four-way vehicle track 102. The lifting mechanism 3 is provided on the base frame 1, and the power output end is connected to the transfer conveyor line 2, which can lift and lower the transfer conveyor line 2.

[0078] Among them, the automatic guided vehicle 6 is preferably a hidden lift AGV (hidden lift automatic guided vehicle), which has a built-in lifting system that can be used to lift and place goods. It can easily enter and maneuver narrow spaces.

[0079] In large storage centers, the AGV can move freely in narrow passages to lift and place goods. It can be used to move parts from one assembly site to another, and the AGV can be used to connect production links, carry out material turnover, and automatically dock in and out of the warehouse. It is widely used in various logistics scenarios. Based on the flexibility and flexibility of AGV and the logistics method without ground fixed equipment, the AGV is often used with a bracket to facilitate the docking and turnover of materials.

[0080] While the combination of the latent lifting AGV and the pallet bracket facilitates logistics turnover, it also brings problems to the automated docking of materials in and out of the warehouse, and the automated separation of the latent lifting AGV bracket and the pallet.

[0081] During use of the transfer device of the embodiment of the present invention, the automatic guided vehicle 6 can carry the pallet in a lifted state and move it to the guide vehicle introduction part 101 on the base frame 1, and then lower the pallet and place it on the transfer conveyor line 2. The lifting mechanism 3 can lift the transfer conveyor line 2, thereby leaving enough space for the four-way vehicle 7 to enter and exit. The pallet can move to the top of the four-way vehicle track 102 under the transportation of the transfer conveyor line 2. The four-way vehicle 7 can move to the bottom of the pallet through the four-way vehicle track 102, and then the lifting mechanism of the four-way vehicle 7 is lifted, and it carries the pallet away from the four-way vehicle track 102, thereby completing the connection between the four-way vehicle 7 and the pallet, and then the four-way vehicle 7 completes the subsequent warehousing task.

[0082] Therefore, the transfer device of the embodiment of the present invention can realize the automatic separation of the automatic guided vehicle 6 and the pallet and the docking of the automatic guided vehicle 6 with the four-way vehicle warehouse, can realize fully automatic entry and exit of the warehouse, improve the automation level of logistics, reduce the labor intensity of the operator, and avoid the error rate caused by manual operation, which can improve production efficiency.

[0084] The lifting height of the lifting mechanism 3 can be set according to the model of the four-way vehicle 7 so as to reserve enough space for the four-way vehicle 7 to enter the four-way vehicle track 102 .

[0085] Exemplarily, after the lifting mechanism 3 is lifted, the bottom height of the pallet can be optionally raised to 505 mm.

[0086] In a preferred embodiment, the lifting mechanism 3 can raise the height of the transfer conveyor line 2 by 40 mm. Under the action of the lifting mechanism 3, the height of the bottom of the pallet rises to 515 mm.

The guide wheels 402 are disposed in pairs and are respectively disposed on both sides of the guide column 401.

[0112] Through such an arrangement, when the lifting mechanism 3 raises or lowers the transfer conveyor line 2, the guide wheel 402 can slide along the guide column 401, thereby constraining the movement path of the transfer conveyor line 2.

[0113] In one embodiment, the guide column 401 is a guide square steel.

[0114] By such arrangement, the contact area between the guide wheel 402 and the guide column 401 can be increased, so that the movement of the guide wheel 402 is more stable.
