Allocate to both sides of 41, for example, detector of light emitting / receiving type
60 is provided, which confirms the presence of other things.

A cool air supply device 65 is provided to supply cool air into the surrounding wall body 21. That is, the compressor unit 66 is arranged separately from the side of the wall body 21, and the refrigerant pipe 67 from the compressor unit 66 is provided in the wall body 21 and above the cradle 42 in a cooler (evaporator). Connected to 68. A front air supply chamber 70 is formed by a front partition plate 69 at a corner portion formed by the front wall plate 21A and the top wall plate 21E in the surrounding wall body 21, and the cooler 68 is provided in the front air supply chamber 70. Are in communication. The front partition plate 69 is formed with a downward slit air outlet facing the central portion. A rear air supply chamber 72 is formed by a rear partition plate 71 at a corner portion formed by the rear wall plate 21B and the ceiling wall plate 21E, and this rear partition plate 71 is also formed with a slit outlet similar to that described above. Both air supply chambers 70, 72 are provided with a ceiling duct 73 formed under the ceiling wall plate 21E, and 77 is a foot switch. A control panel 78 is provided below the operation panel 43 and on the front side of the front wall plate 21A, and the operation panel 43, a foot switch 77, and the like are connected to the control panel 78. When the shutter device 44 is closed, the drive device 28 is provided in the control panel 78.
A timer etc. is built in to operate intermittently at the set time.

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

In FIG. 6, by pressing the call on the operation panel 43,
First, the contact switch 52 determines whether the shutter plate 45 is closed.
It is determined based on the signal from. When the result is NO, the shutter plate 45 is closed (described later). If yes, it is confirmed that the shutter plate 45 is closed, and if yes, the drive device 28 is actuated to move the endless rotary body 25 forward and backward, thereby moving the bucket 33 group. Then, when the target bucket 33 is stopped facing the loading / unloading port 41, the lifting drive device 55 is actuated, and the shutter plate 45 is pulled up via the roller chain 56 that is moved by the rotation of the drive chain wheel 58. The loading / unloading port 41 is automatically opened. As a result, articles can be loaded and unloaded through the loading / unloading port 41. After finishing such work, it is judged whether or not there is a next work continuously, and in the case of Yes, it returns to the work of pushing the call again. When the next operation is NO, the foot switch 77 is depressed to shift to the shutter closing operation. That is, by operating the foot switch 77, the lifting drive device 55 is operated in the opposite direction to the above, and the drive chain wheel is
This can be done by lowering the shutter plate 45 via the roller chain 56 that moves by the reverse rotation of 58. When the shutter plate 45 is completely lowered, the close limit is confirmed by the proximity switch 52 as described above, and the lifting drive device 55 is stopped. The same applies to the opening limit when the elastic stopper 53 is contacted downward, which is detected by the proximity switch 54 and the lifting drive device 55 is stopped. When the loading / unloading port 41 that has been opened has a human hand or another object such as an article, the detector 60 detects it, so that even if the foot switch 77 is stepped on, the shutter plate 45 does not descend, and the bucket 33 The group does not move. When the shutter plate 45 is opened and closed as described above, the counterweight 59 balances the shutter plate 45 guided by the guide rails 48 and 49 via the rollers 46 and 47 as shown by the phantom line in FIG. Front wall plate 2
As it is separated from 1A etc., it can be lifted and lowered smoothly. Moreover, in the lower limit (when closed), the rollers 46, 47 are guided by the inclined rail portions 48a, 49a, so that the shutter plate 45 moves closer to the loading / unloading port 41 side as shown by the solid line in FIG. When the lower end contacts the elastic stopper 51, the front surface comes into pressure contact with the sealing material 50 against elasticity, whereby the loading / unloading port 41 is sealed.

During operation, cool air (cooling air) supplied from the cooler 68 from the compressor unit 66 through the refrigerant pipe 67.
The air A is blown out from the front air supply chamber 70 into the enclosure 21, and is further blown out from the rear air supply chamber 72 through the ceiling duct 73.

When the shutter plate 45 is closed, it is determined whether or not there is work, as shown in FIG. In the case of yes here, we will move to the work described above. On the other hand, when the result is NO, the timer is timed from the closing of the shutter described above, and when a certain time (for example, 3 minutes) elapses, the drive device 28 is operated in the normal or reverse direction, whereby the bucket 33 group is moved. Then, the group of buckets 33 is the wall 21
The cold air inside is agitated, so that the temperature inside the enclosure 21 is made uniform. The above-mentioned operation of the drive device 28 is for a set time (for example, 30 seconds), which causes the bucket 33 group to stop at the next fixed position. In addition, after the set time has elapsed, the timekeeping by the timer is repeated again,
Therefore, the stirring operation for the set time described above is intermittently repeated. When "working" occurs during such stirring work, and when the bucket 33 group is performing stirring motion, as described above, the bucket 33
It will enter the cycle of work after the group has stopped at the next home position.

In the above description, the form in which the stirring motion is intermittently repeated based on the timing of the timer is shown. However, as shown by the phantom line in FIG. 1, for example, an upper temperature sensor 79 is provided near the rear partition plate 71 and A lower temperature sensor 80 may be provided near the carry-in / out port 41, and when the difference between the temperatures detected by these temperature sensors 79, 80 exceeds a certain value, the bucket 33 group may be moved and stirred.

EFFECTS OF THE INVENTION According to the present invention having the above-mentioned configuration, the inside of the enclosure can be made into a refrigerator by the cold air blown out from the cold air supply device, whereby articles such as fresh food can be stored. When the shutter is closed and operation continues for a long time, such as at night, or when the opening time of the shutter device becomes long in the previous work, the drive device is intermittent for the set time when the shutter device is closed. Driven, and when temperature unevenness occurs due to temperature rise near the loading / unloading port, the driving device is driven, whereby the bucket group can be moved to stir the cold air in the enclosure, and the temperature can be made uniform. It is possible to prevent damage to fresh food products.
