The present disclosure provides a storage rack supply system that supplies a storage rack that is capable of being switched between a storage disabled state in which a partition portion is in a folded state and a storage enabled state in which the partition portion is raised to be capable of storing, a shipment system that stores and ships an object to be stored in the storage rack capable of storing, and a storage rack handling device for handling storage racks that can be switched between the storage disabled state and the storage enabled state.
Conventionally, for example, Japanese Unexamined Patent Application Publication No. H10-310208 A (hereinafter referred to as Patent Document 1) discloses that a foldable storage rack is used to transport large tires (objects to be stored) used for buses and trucks. After support pillars (partition portions) of the storage rack are raised to make the storage rack in a storage enabled state, the storage rack is tilted to store the tires in the storage rack by a forklift. Furthermore, after changing a posture of the storage rack horizontally by a posture changing device of the storage rack, a plurality of large tires stored together with the storage rack are transported to the storing section by the forklift.
Although Patent Document 1 does not particularly describe a change in a storage form of the storage rack, it is assumed that a worker performs such a change.
Japanese Patent No. 2539241 B (hereinafter referred to as Patent document 2) discloses that a group of stacked tires is transported from a storage section while maintaining a stacked state. While being transported, the tires are separated one by one and inspected. After that, a plurality of tires of the same type and the same size are stacked to form again a group of stacked tires and transported to the shipping section. The group of stacked tires transported to the shipping section is changed in posture to a horizontal posture that is in a horizontally aligned state. The group of stacked tires is stored in the storage rack in a horizontal posture. After that, storage racks in which the groups of tires are stored are stacked.
In Patent Document 1, a storage rack that can be switched between a storage enabled state and a storage disabled state is employed to transport a group of tires. It is assumed that the worker who operates the forklift switches the state of the storage rack each time before storing the tires. In this case, there is a possibility that work efficiency will be lowered. In addition, in the case of a large-mass object to be stored (for example, a large tire or a roll body in which a continuous sheet-shaped member is wound into a roll), since a storage rack with high strength and rigidity is adopted, the mass of a movable partition itself also increases. In this case, switching the state of the storage rack by the worker may increase the physical burden on the worker.
Patent Document 2 discloses a shipment system that uses storage racks that are in a storage enabled state. In this shipment system, in order to prepare a plurality of storage racks that are in the storage enabled state, a space for preparation is required.

The configuration of the storage rack supply system 2 and the like of the present embodiment can be variously modified as described below.
A rack preparation section 65 configured in a storage rack supply system 2A of the first modification shown in
Each of the first partition moving unit 156A and the second partition moving unit 156B are configured similarly to the partition moving unit 67. The first partition moving unit 156A is arranged on one side of the preparation transport unit 70 in the width direction, and the second partition moving unit 156B is arranged on the other side of the preparation transport unit 70 in the width direction.
The first partition moving unit 156A has a first engaging portion 157A that is capable of engaging with a first engaged portion (engaged portion) 211a set in the first partition portion 211 or a second engaged portion (engaged portion) 221a set in the second partition portion 221.
In the first modification, the first engaging portion (engaging portion) 157A of the first partition moving unit 156A engages with the first engaged portion (engaged portion) 211a set in the first partition portion 211. The first partition moving unit 156A moves the first engaging portion 157A in the vertical direction and the second installation direction Y.
The second partition moving unit 156B is provided with a second engaging portion 157B that is capable of engaging with the first engaged portion (engaged portion) 211a set in the first partition portion 211 or the second engaged portion (engaged portion) 221a set in the second partition portion 221.
In the first modification, the second engaging portion (engaging portion) 157B of the second partition moving unit 156B engages with the second engaged portion (engaged portion) 221a set in the second partition portion 221.
The second partition moving unit 156 moves the second engaged portion 221a in the vertical direction and the second installation direction Y.
In the partition moving unit 155 of the rack preparation section 65 of the first modification, the first partition moving unit 156A moves one of the first partition portion 211 and the second partition portion 221, and the second partition moving unit 156B moves the other of the first partition portion 211 and the second partition portion 221. In
In addition,
In the storage rack supply system 2A configured as described above, the first partition moving unit 156A moves the first engaging portion 157A, thereby moving the first partition portion 211 by engaging the first engaging portion 157A with the first engaged portion 211a of the first partition portion 211 arranged on the positioning portion 73 side. As a result, it is possible to use the first partition moving unit 156A exclusively for raising the first partition portion 211 of the storage rack 200 with respect to the base portion 202.
Similarly, the second partition moving unit 156B moves the second engaging portion 157B, thereby moving the second partition portion 221 by engaging the second engaging portion 157B with the second engaged portion 221a of the second partition portion 221 arranged on the stopping unit 72 side. As a result, it is possible to use the second partition moving unit 156B exclusively for raising the second partition portion 221 of the storage rack 200 with respect to the base portion 202.
The partition moving unit 155 employed in the rack preparation section 65 of the storage rack supply system 2A can improve work efficiency by moving the first partition portion 211 and the second partition portion 221 with the first partition moving unit 156A and the second partition moving unit 156B dividing the task thereof.
In addition, without providing the movement assisting unit 68 configured in the rack preparation section 65, one of the first partition moving unit 156A and the second partition moving unit 156B substitutes for the work performed by the movement assisting unit 68, and the other thereof may move the first partition portion 211 and the second partition portion 221. In addition, the first partition moving unit 156A and the second partition moving unit 156B may replace the moving mechanisms for moving each of the first engaging portion 157A and the second engaging portion 157B with multi-joint moving mechanisms, and may employ a dual-arm robot having each multi-joint movement mechanism on one support portion.
In the present embodiment, the storage rack is not particularly limited as long as it has the base portion and the partition portion. For example, as in a second modification shown in
Each partition portion 237 is foldable with respect to the base portion 236. When sequentially moving the four partition portions 237 of the storage rack 235 described above, it is possible to employ the partition moving unit of the present embodiment.
As described above, one embodiment of the present invention has been described in detail with reference to the drawings, however the specific configuration is not limited to this embodiment, and the configuration can be changed, combined, deleted, or the like, without departing from the scope of the present invention.
For example, in the above embodiment, the partition moving unit 67 may not have to have the engagement position moving mechanism 96.
The partition moving unit 67 may have an integrated mechanism for moving the engaging portion 90 in the vertical direction and the second installation direction Y instead of the moving mechanisms 94 and 95.
The shipment system 1 may not have the discrimination unit 142, the engagement position determination unit 143, the storage rack determination unit 144, and the rack supply section determination unit 145.
The rack preparation section 65 may not have the upper partition detection portion 69.
The engaging portion may engage with the partition portion by attraction, electric or magnetic force.
The object to be stored is assumed to be a tire. However, the object to be stored is not limited to a tire, and may be a roll of paper, cloth, or the like, or may be a rectangular or circular plate-like member.
