The effects of the automated warehouse system 100 of the above embodiment will be explained. In the automated warehouse system 100 of the above embodiment, by rotating the pallet P on which the roll material R is placed, the roll material R can be separated from the pallet P and delivered to the second conveyance device 3. Then, the delivered roll material R is delivered to the stacker crane 5 by the second conveyance device 3, and the stacker crane 5 transfers the roll material R onto the rack 7. That is, in the automated warehouse system 100 having this configuration, the roll material R that has been transported while being placed on the pallet P can be separated from the pallet P and stored in the rack 7.

In the automated warehouse system 100 of the above embodiment, the transport device includes a switching unit 33 that switches the transport direction of the roll material from the X direction to the Y direction, or from the Y direction to the X direction, and the rack 7 is The stacker crane 5 is configured to be able to store a plurality of roll materials R along the X direction, and is provided movably along the X direction and transfers the roll materials along the Y direction. Thereby, the roll material R is stored in the rack 7 such that the extending direction of the axis C of the roll material R matches the extending direction (X direction) of the rack 7. In general, the rack 7 is stronger against shaking in the extending direction than in the width direction (direction perpendicular to the extending direction), so the amount of displacement of the roll material R during an earthquake can be reduced.

In the automated warehouse system 100 of the embodiment described above, the second conveyance device 3 includes two

connection sections

39 and 39 and a distribution section 37.

Although the automated warehouse system 100 of the above embodiment has been described with reference to an example in which the second transport device 3 includes the switching unit 33 that switches the transport direction of the skid S, it may be configured without the switching unit 33. That is, after receiving the roll material R from the roll rotation device 2, the second conveyance device 3 directly conveys the skid S on which the roll material R is mounted to the rack 7 in the X direction without switching the conveyance direction. It is also possible to have a configuration in which In this case, the rack 7 is arranged so as to extend along the Y direction (that is, so that the storage sections 75 are arranged in the Y direction). The roll material R may be stored in the rack 7 in such a state that the axis C extends in the Y direction.

In the automated warehouse system 100 of the above embodiment and modified example, the second conveyance device 3 has been described with reference to an example in which it has two

connection parts

39, 39, but only one connection part 39 may be provided, Three or more connections 39 may be provided. As a modification, when only one connection section 39 is provided, the distribution section 37 may not be provided.

In the automated warehouse system 100 of the above embodiments and modifications, the explanation has been given using an example in which the sorting section 37 moves in the X direction. The device 2 may also be connected.

In the automated warehouse system 100 of the above embodiments and modifications, the roll material R supplied via the first conveyance device 1 is changed in position by the roll rotation device 2, and is stored in the rack 7. Although the description has been given above, the invention is not limited thereto. For example, the position of the roll material R taken out from the rack 7 may be changed by the roll rotation device 2, and then sent to the first conveyance device 1. In this case, the roll rotation device 2 does not necessarily have to return the rotation member 23 from the second state to the first state after the skid S has left the roll rotation device 2, and the roll rotation device 2 does not necessarily have to return the rotation member 23 from the second state to the first state, and the roll rotation device 2 does not necessarily have to return the rotation member 23 from the second state to the first state. The rotating member 23 may be rotated from the second state to the first state only when this is done. In other words, when the roll rotation device 2 receives the roll material R taken out from the rack 7 after leaving the skid S, the roll rotation device 2 waits in the second state without returning from the second state to the first state. It's okay.

In the automated warehouse system 100 of the above embodiments and modifications, the stacker crane 5 has been described as an example of a device for transferring the roll material R onto the rack 7. A shuttle transport device that moves above the rack 7, a lifting device that moves along the vertical direction of the rack 7, or a combination of these devices may be used.
