Next, the operation of the above embodiment will be explained.

In FIG. 6, by pressing the call button on the operation panel 43, it is first determined based on the signal from the proximity switch 52 whether or not the shutter plate 45 is closed. If the answer is no, the closing operation of the shutter plate 45 (described later) is performed, and if the answer is yes, the closing of the shutter plate 45 is confirmed, and if the answer is yes, the drive device 28 is activated to move the endless rotating body 25 in the correct position. By moving backward, the bucket 33 group is moved. And the target bucket 3
3 is stopped facing the loading/unloading port 41, the lifting drive device 55 is activated, and the shutter plate 45 is pulled up via the roller chain 56 that moves due to the rotation of the drive rivet shaft 58, thereby opening the loading/unloading port 41. automatically open and move. Thereby, articles can be carried in and out through the carry-in/out port 41. After completing such work, it is determined whether there is any next work to be done, and if the answer is yes, the process returns to the work of pressing the call button again. If the next operation is no, stepping on the foot switch 77 causes the shutter to close.

That is, by operating the foot switch 77, the lifting drive unit N
This can be done by operating the shutter plate 55 in the opposite direction to that described above and lowering the shutter plate 45 via the roller chain 56 that moves due to the reverse rotation of the drive riveter shaft 58. When the shutter plate 45 is completely lowered, the closeness of the eyes is confirmed by the proximity switch 52 as described above, and the elevating drive device 55 is stopped.

Similarly, the opening of the eye when it comes into contact with the downward elastic stopper 53 is detected by the proximity switch 54 and the lifting drive device 55 is stopped. Note that if there are other objects such as people or goods at the loading/unloading exit 41 that is opened,
Since the detector 60 detects this, even if the foot switch 77 is stepped on, the shutter plate 45 will not descend and the bucket group 33 will not move. During the opening and closing operations of the shutter plate 45 as described above, the counterweight 59 acts as a balance, and the shutter plate 45 is guided by the guide rails 48 and 49 via the rollers 46 and 47 as shown by imaginary lines in FIG. Since it is spaced apart from the front wall plate 21A, etc., it can be lifted and lowered easily and smoothly.

Moreover, at the lower limit (during closing movement), roller 46.47
is guided by the inclined rail parts 48a and 49a, the shutter plate 45 moves toward the carry-in/outlet 41 side as shown by the solid line in FIG. It comes into pressure contact with the material 50 against elasticity, thereby sealing the loading/unloading port 41.

During operation, cold air (cooling air) A supplied from the cooler 68 from the compressor unit 66 via the refrigerant pipe 67 is blown out from the front air supply chamber 70 between the inside covers 3A and 3B in the surrounding wall 21. The air is then blown out from the rear air supply chamber 72 via the ceiling duct 73.

The cold air supply device 65 that supplies cold air in this way and the drive device 28 are configured to be stopped while the shutter device 44 is being opened. In other words, in FIG. 7, the output from the inverter 78 is for either rotation selection or shutter selection, so that the drive unit W1
28 and the lifting drive device 55 are operated reversibly, so that the bucket 33 is not moved while the shutter bag opening 44 is being opened. Furthermore, when the shutter is selected, the blowing of cold air A from the cold air supply device 65 is also stopped, and at this time, the cold air supply device 65 is in run-up operation. The cool air blown from the device between the inside covers can be efficiently used as a refrigerator, allowing for the storage of fresh foods and other items.

Further, when the shutter device is moved to close, the movement of the bucket can be stopped by stopping the drive device, and the blowing of cold air can be stopped by stopping the cold air supply device. As a result, cold air does not flow inside the enclosure, which greatly reduces the outflow of cold air from the open delivery pile, as well as the inflow of outside air, making it possible to equalize the internal temperature and control the temperature. can be done easily and without waste.
