BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-level automatic warehouse capable of storing goods and vehicles over multiple floors.

0002

2. Description of the Related Art Among multi-story automatic warehouses, for example, multi-story parking garages include a plurality of parking floors each having a plurality of parking rooms. Some multi-story parking lots of this type carry cars on pallets between the entrance and exit and the parking room via an elevator device and a traversing trolley. but,
In this format using pallets, there is waste in transporting empty pallets. Therefore, it has been proposed to provide a loading/unloading device, an elevator platform, a traversing cart, and a parking room with a slat conveyor that supports the running wheels from below.

0003

[Problems to be Solved by the Invention] However, in the case where the above-mentioned slat conveyors are provided, cars are delivered with the slat conveyors close to each other, so there is a difference in the diameter of the sprocket during the delivery, which makes the delivery of cars difficult. There was a problem that a positional shift occurred. Additionally, a drive device is required for both slat conveyors, but especially if a drive device is added to the slat conveyor in a parking lot with multiple floors, the height between each parking level will be higher than that of a pallet type, reducing the parking space capacity. The problem arises. Particularly in the case of an underground type, there are problems in that the depth of underground excavation increases, which increases excavation costs, and reduces the number of parking spaces.

[0004] An object of the present invention is to provide a three-dimensional automated warehouse that can solve the above problems.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the first means of the automatic warehouse of the present invention is to provide an elevator device capable of transporting cargo by raising and lowering a lifting platform over a plurality of storage floors; Multiple storage rooms located on each floor,
In a three-dimensional warehouse facility comprising a transverse trolley that is movably arranged along the storage room and capable of transferring cargo between the elevator device and the storage room, the elevating platform of the elevator device, the storage room, and the transverse trolley are provided. A conveyor device is installed to support the load from below and transfer it freely to the loading/unloading side.
A drive-type multi-strip conveyor device comprising a multi-strip conveyor device in which a plurality of rows of movable bodies are arranged at predetermined intervals in a direction perpendicular to the transfer direction, and a conveyor drive device is provided in at least the multi-strip conveyor device of the traversing cart. In addition, the multi-strip conveyor device in the storage room is an idling-type multi-strip conveyor device,
With respect to the drive-type multi-strip conveyor device of the transverse cart, the elevating platform of the elevator device and the entrance/exit end of the multi-strip conveyor device of the storage room are configured so that they can overlap each other by shifting their phases, and A conveyor egress/egress device is provided in which the driven multi-strip conveyor device is projected from the lifting platform of the elevator device and the multi-strip conveyor device side of the storage room so that their tips overlap each other, and a drive-type multi-strip conveyor device is installed on the traversing cart. A conveyor lifting device is provided that can raise and lower the loading and unloading end of the storage room above and below the load support level of the lifting platform and the multi-strip conveyor device in the storage room.

[0006] The second means includes an elevator device capable of transporting cargo by raising and lowering a lifting platform across a plurality of storage floors, and an elevator device that is disposed on each storage floor and is capable of transferring cargo between the elevator device and the lifting platform. In a multi-story warehouse facility equipped with multiple storage rooms, a conveyor device is installed in the lifting platform of the elevator device and in the storage room so that the cargo can be supported from below and transferred to the loading/unloading side. a multi-strip conveyor device in which a plurality of rows of movable bodies are arranged at predetermined intervals in the direction of The multi-strip conveyor device in the storage room is an idling-type multi-strip conveyor device, and the input/output side ends of the multi-strip conveyor device in the storage room are shifted in phase and overlapped with the drive-type multi-strip conveyor device in the lifting platform. A conveyor exit/exit device is provided in which the drive-type multi-strip conveyor device of the lifting platform is respectively protruded toward the multi-strip conveyor device side of the storage room so that their tips overlap with each other, and the drive-type multi-strip conveyor device of the lifting platform is provided with A conveyor lifting device is provided that can raise and lower the loading/unloading side end of the strip conveyor device above and below the load support level of the multi-strip conveyor device in the storage room.

[0007]

[Operation] According to the above structure, when a load is carried into the storage room from a traversing cart or a lifting platform, the end of the multi-strip conveyor device on the side of the storage room is positioned at the same level or slightly above the load support level, and the conveyor The egress/egress device is driven to overlap the storage room side end of the drive type multi-strip conveyor device with the elevator device side end of the idling-type multi-strip conveyor device. Next, the conveyor drive device drives the driven multi-strip conveyor device to transfer the load from the driven multi-strip conveyor device on the traversing truck to the free-rotating multi-strip conveyor device in the storage room.

[0008] Furthermore, when transporting a load from the storage room to a traversing cart or a lifting platform, the conveyor lifting device moves the end of the drive type multi-strip conveyor device on the storage room side to the cargo of the free-rotating multi-strip conveyor device in the storage room. While lowered below the support level, drive the conveyor egress/removal device to move the multi-strip conveyor device so that the end on the storage room side overlaps the end on the space side of the free-rotating multi-strip conveyor device to remove the cargo. Position it below the bottom. Then, using the conveyor lifting device, the storage chamber side end of the driven multi-strip conveyor is raised to the same level or slightly above the load support level and brought into contact with the bottom of the load supported on the free-rotating multi-strip conveyor. . Next, the conveyor drive device drives the driven multi-strip conveyor device to transfer the load from the idle-rotating multi-strip conveyor device in the storage room to the driven multi-strip conveyor device in the traversing truck.

[0009] The same procedure as described above can also be carried out when loading and unloading cargo between the lifting platform of the elevator system and the traversing truck. Therefore, since the load can be transferred with the conveyor devices engaged, it is possible to transfer the load extremely smoothly and prevent the load delivery position from shifting. Moreover, even if there is no conveyor drive device on the conveyor side of a large number of storage rooms, it is possible to transport and move loads within the range where the end of the drive-type multi-strip conveyor device on the storage room side is in contact with the bottom of the load. Furthermore, by using an idling-type conveyor device as the conveyor device in the storage room, the thickness of the conveyor device can be reduced and the height of the storage room can be lowered, allowing effective use of space.
