[0026] Embodiment 1

[0027] This embodiment provides a tray cargo storage system, as Figures 1 - 3 shown, including multiple rows of shelves 1, and the multiple rows of shelves 1 form a shelf assembly. Adjacent rows of shelves are arranged in contact with each other so that each row of the shelves has multiple storage locations. At least one shuttle component is correspondingly arranged for each row of storage locations. The shuttle component adopts a shuttle car. The multiple storage locations in each row are distributed along the traveling direction of the shuttle car. Each storage location of the shelf is provided with a first guide rail 2 for cooperating with the shuttle car. The outer side of the first guide rail 2 is provided with a first support beam 3 for supporting the tray. The top surface height of the first tray support beam 3 is higher than the top surface height of the first guide rail 2.

[0028] Preferably, the first tray support beam 3 and the first guide rail 2 are integrally formed.

[0029] Lifting mechanisms are arranged on both sides of the shuttle car. The lifting mechanism can adopt the existing lifting mechanism for the shuttle car, and its specific structure will not be described in detail here. The lifting mechanism includes a lifting component, and the lifting component is connected with a lifting plate. The lifting plate is used for cooperating with the tray to lift the tray.

[0030] In this embodiment, the lifting plate can drive the tray to lift, so as to realize placing the tray on the first support beam or separating the tray on the first support beam from it.

[0031] An air transfer device is arranged on one side or both sides of the shelf assembly. The air transfer device is used for sending the tray into the shelf or sending it out of the shelf.

[0032] The air transfer device includes a mother vehicle 4. Traveling mechanisms 5 are arranged on both sides of the mother vehicle 4. The traveling mechanisms 5 on both sides cooperate with the traveling track 6. The mother vehicle 4 can travel along the traveling track 6.

[0033] In this embodiment, the traveling track 6 on one side of the mother vehicle 4 is fixed on the shelf 1. Preferably, it is fixed on the top of the shelf 1. The traveling track 6 on the other side is connected with the track support 7. The track support 7 is fixed on the ground foundation or the ceiling.

[0034] In another embodiment, the traveling tracks 6 on both sides of the mother vehicle 4 are fixed to the track brackets 7, and the track brackets 7 are fixed to the ground foundation or the ceiling.

[0035] Two sets of traveling mechanisms 5 are provided on both sides of the mother vehicle 4. The traveling mechanism 5 includes traveling wheels, and at least one traveling wheel is connected to a traveling drive motor installed on the mother vehicle 4.

[0036] The mother vehicle 4 is connected to the loading platform 8 below it through a plurality of lifting belt mechanisms, and the mother vehicle 4 can drive the loading platform 8 to lift through the lifting belt mechanisms.

[0037] In this embodiment, lifting belt mechanisms are installed at the four corners of the mother vehicle 4. The lifting belt mechanism includes a rotation drive member, and the rotation drive member uses a rotation drive motor 9 installed on the mother vehicle. The output shaft of the rotation drive motor 9 is connected to a belt pulley 10, and a lifting belt is wound around the belt pulley 10. The lifting belt extends downward after passing around a guide pulley installed on the mother vehicle 4. After passing through the mother vehicle 4, the movable end of the lifting belt is connected to the loading platform 8.

[0038] The rotation drive motor 9 drives the belt pulley 10 to rotate, so as to be able to drive the loading platform 8 to lift through the lifting belt.

[0039] The loading platform 8 is provided with a second guide rail matching the first guide rail 2 and a second support beam matching the first support beam 3. The second guide rail is arranged inside the corresponding second support beam. The top surface height of the second support beam is higher than the top surface height of the second guide rail. The second guide rail is used to cooperate with the shuttle vehicle for the shuttle vehicle to travel, and the second support beam is used to support the pallet.

[0040] Above the loading platform 8, a detection element is provided to detect whether there is a cargo or a shuttle vehicle on the loading platform. In this embodiment, two detection elements are provided above the loading platform. The detection elements use photoelectric sensors 11. The two photoelectric sensors 11 are respectively arranged on the feeding side and the discharging side of the loading platform 8 and are at a set height from the loading platform 8. The photoelectric sensors 11 are fixedly connected to a bracket, and the bracket is fixedly connected to the loading platform 8. The two photoelectric sensors 11 are used to detect whether the pallet and the cargo are transferred onto the loading platform.

[0041] Further, along the traveling direction of the mother vehicle 4, at least one buffer assembly is provided on both side edges of the mother vehicle 4. The buffer assembly is made of a flexible block, preferably made of a rubber block.

[0042] At least one buffer assembly is also provided on the bottom surface of the loading platform 8. The buffer assembly is made of a flexible block, preferably made of a rubber block.

[0043] The warehousing method of the pallet cargo storage system in this embodiment is as follows:

[0044] The shuttle on the cargo platform 8 carries the pallet 12 and the goods 13 on the pallet 12, the mother vehicle 4 moves along the walking track 6, the lifting belt drives the cargo platform 8 to rise and fall, so that the cargo platform 8 moves to the row where the target cargo position is located, and then the shuttle drives the pallet 12 and the goods 13 to rise a set distance through the lifting mechanism, and then the shuttle enters the shelf 1, walks through the first guide rail 2 until it moves to the target cargo position, the lifting mechanism drives the pallet 12 to descend, and the pallet 12 is placed on the first support beam 3 of the target cargo position, completing the warehousing of the goods.

[0045] The outbound method of the pallet cargo storage system of this embodiment is:

[0046] The mother vehicle 4 moves along the running track 6, and drives the cargo platform 8 to descend to the row where the target cargo position is located through the lifting belt mechanism. The shuttle vehicle moves to the target cargo position, and drives the pallet 12 to be lifted up through the lifting mechanism, so that the pallet 12 is separated from the first support beam 3. Then the shuttle vehicle drives the pallet 12 and the cargo 13 to move to the shuttle vehicle, and the lifting mechanism drives the pallet to descend, and the pallet is placed on the second support beam. The mother vehicle 4 and the lifting belt mechanism work together to move the pallet 12 and the cargo 13 to the outbound position, thereby realizing the outbound delivery of the cargo.

[0047] In the pallet cargo storage system of the present embodiment, the aerial transfer device is arranged on one side of the shelf, and a shuttle car is used to place the pallet and cargo into multiple cargo spaces in each row or to pick up cargo from multiple cargo spaces in each row. The shelf does not need to be provided with aisles, which greatly saves the shelf space and improves the applicability of the entire storage system to the site. Moreover, after the shuttle car moves to the bottom of the pallet, it picks up and releases the cargo through the lifting mechanism. After the shuttle car picks up the cargo, it moves to the loading platform through the first guide rail and the second guide rail, thereby picking up the cargo from the loading platform. The loading platform does not need to pick up the cargo through the telescopic fork component, which avoids the risk of tipping over of the hollow transfer device caused by heavy cargo.

[0048] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
