The functions of the ground controller 32C and the crane controller 35 will be described with reference to the flowcharts of FIGS. The UV controller 28 of the storage section 2 in which the operation box 5 is stored has a ground controller 32C.
It is assumed that power is supplied via the output contact 32D. The description of the screen display of the CRT 32B by the ground controller 32C is omitted. Further, transmission and reception of signals between the ground controller 32C and the crane controller 35 are performed via the photoelectric device 34.

First, the ground controller 32C sends the work mode (entry or exit) from the keyboard 32A and the shelf 3
When it is confirmed that the work data including the position numbers of the storage sections 2 of A and 3B has been input (step-1), the output contacts
Power is supplied to the ultraviolet sterilizing lamp 27 on the ceiling 1A via 32D to light it (step-2). Next, from work mode,
Determine whether the operation is a receiving operation or a leaving operation (Step-
3). If it is determined in the work mode that the operation is a warehousing operation, the crane controller 35 outputs a traveling command signal to the position of the warehousing conveyor 16 of the loading / unloading device 15 (step-
4).

The crane controller 35 drives the traveling driving device 37 in response to the traveling command signal to drive the loading / unloading device 15.
Is moved to the storage conveyor 16 position (step-5), and a storage position arrival signal is output to the ground controller 32C (step-6).

When the ground controller 32C confirms the arrival signal of the loading / unloading device 15 at the storage conveyor 16 (step-7), it outputs an open signal to the storage shutter 18 (step-8). Is driven for a predetermined time to carry in the operation box 5 (step-9), and subsequently outputs a storage command signal and position data of the storage section 2 of the shelves 3A and 3B to be stored to the crane controller 35 (step-10).

The crane controller 35 drives the elevating / lowering drive unit 36 and the retracting unit 38 in response to the storage command signal to transfer the operation box 5 from the storage conveyor 46 to the loading / unloading tool 25 (step-11). Subsequently, in accordance with the position data of the storage section 2 of the shelves 3A, 3B, the traveling drive device 37, the lifting drive device 36, and the retraction device 38 are driven to drive the target shelves 3A, 3B.
The operation box 5 is stored in the storage section 2 of Step B (Step-1).
2) Output a warehousing work end signal to the ground controller 32C (step-13).

The ground controller 32C has a surgical box 5
When the transfer to the loading / unloading device 5 is confirmed by the operation of the sensors 33 (Step-14), a close signal is output to the storage shutter 18 (Step-15), and when the input of the storage work end signal is confirmed (Step-14). -16), the power is supplied to the ultraviolet sterilization lamp 28 of the storage section 2 of the shelves 3A and 3B in which the operation box 5 is stored via the output contact 32D and turned on (step -1).
7) The output contact 32D is turned off, the ultraviolet sterilization lamp 27 on the ceiling 1A is turned off (step-18), and the process ends.

When it is determined in step 3 that the operation is a retrieval operation, a retrieval command signal and data on the position data of the storage unit 2 of the shelves 3A and 3B to be retrieved are output to the crane controller 35 (step 3). 19).

The crane controller 35 includes shelves 3A, 3B
In accordance with the position data of the storage section 2, the driving device 37, the lifting drive device 36, and the retracting device 38 are driven to move the operation box 5 from the storage section 2 of the target shelf 3A, 3B onto the loading / unloading tool 25. (Step-20), and then the traveling drive unit 3
7. Driving the lifting / lowering drive device 36 and the retraction device 38 to release the operation box 5 to the target retrieval conveyor 17 (step 21), and outputs a retrieval completion signal to the ground controller 32C (step 22). .

When the ground controller 32C confirms the input of the retrieval operation end signal (step-23), it outputs an open signal to the retrieval shutter 19 (step-24), and drives the retrieval conveyor 17 for a predetermined time to operate the operation box. 5 is carried out (step 25), and when the transfer of the operation box 5 from the delivery conveyor 17 is confirmed by the sensors 33 (step 26), a close signal is output to the delivery shutter 19 (step 27) and output. The shelf 3 from which the surgical box 5 is retrieved with the contact 32D turned off.
The ultraviolet sterilizing lamp 28 of the storage section 2 of A and 3B is turned off (Step-28), and the ultraviolet sterilizing lamp 27 of the ceiling 1A is turned off in Step-18.

With the above configuration, first, the ground controller 32
C selects and drives the incoming conveyor 16 or outgoing conveyor 17 in accordance with the work data input from the keyboard 32A and the detection signals of the sensors 33, and further moves the conveyor in and out of the crane controller 35 via the photoelectric device 34. Run command of device 15, lift command signal of lifting body 24, or insertion / removal tool
25, a moving operation on the rails 14 by the loading / unloading device 15, a lifting / lowering movement of the lifting / lowering body 24, and a horizontal movement of the loading / unloading tool 25 are performed. 3
Surgery box 5 for storage unit 2 intended for A, 3B
Is carried out.

During the loading / unloading operation, the ultraviolet sterilizing lamp 27 on the ceiling 1A is turned on to sterilize the operating box 5 during the loading / unloading operation. The ultraviolet sterilization lamp 28 in the storage section 2 of 3B is turned on, thereby preventing the operation box 5 from being infected with MRSA and propagated. Further, the ultraviolet sterilization lamp 28 in the empty storage section 2 is turned off to suppress power consumption.

In the main body 1, a high degree of cleanliness is always maintained. That is, the air blown out of the discharge unit 9 by the operation of the blower 10 rises in the air supply path 7 and passes through the filter 10 to become clean air 12 having a high degree of cleanness. Supplied. Therefore, high cleanliness is maintained in the shelves 3A and 3B by the clean air 12 flowing from the rear surface to the front surface. The clean air 12 that has passed through the shelves 3A and 3B flows into the passage 4, flows into the compartment 8 through the perforated plate 13, is sucked by the blower 10, and is circulated.

In this way, a high degree of cleanliness can be maintained at all times, and the clean operation box 5 can be carried out to the hospital (operating room). Also, UV germicidal lamp
By performing sterilization treatment on the operation box 5 according to 27 and 28, infection and proliferation of the operation box 5 in the facility of the MRSA that has entered the load storage facility can be prevented,
It is possible to prevent the MRSA on the operation box 5 from being taken out to the hospital (operating room), and to prevent the MRSA from entering the hospital (operating room) .

In this embodiment, the ultraviolet sterilizing lamp 2 is used.
Although the lighting and extinguishing of the lights 7 and 28 are controlled by the ground controller 32C, they can be always turned on.
