Next, an operation for drying the tableware will be described.
Usually, since all the tableware is stored in the rotary shelf equipment 1 and drying is performed at once, the case where the tableware is stored in all the buckets 5 will be described here.

  First, the mode switch 31 switches to the skip mode, and the shutter 9 is opened. After the tableware is stored in the empty first bucket 5A at the stop position P as shown in FIG. The ascending switch 36a is pushed. As a result, the first bucket 5A moves upward (rotates), and the third (second skipping) fourth bucket 5D moves to the stop position P and stops (hereinafter, “moves to the stop position”). ").

  After the tableware is stored in the fourth bucket 5D, when the next operation switch 37 is pressed, the fourth bucket 5D moves upward and the next third fourth bucket 5G moves to the stop position P. .

  When this operation is repeated and the endless belt 13 rotates once, the bucket 5 that moves next is shifted by one in a predetermined direction (upper side in the rotational direction) from the first bucket 5A at the start of storage. The second bucket 5B moves to the stop position P.

  Using the second bucket 5B as a reference for starting storage, the tableware is successively skipped two by two and stored in the bucket 5 and the endless belt 13 moves to the stop position P next when the endless belt 13 rotates twice. 5, the third bucket 5 </ b> C shifted by two in the predetermined direction (the upper side in the rotational direction) from the first bucket 5 </ b> A at the start of storage moves to the stop position P.

  Furthermore, when the third bucket 5C is used as a reference for starting storage, and the table is stored in the bucket 5 by skipping two pieces at a time, the last fourteenth bucket 5N eventually moves to the stop position P. It will be.

When the storage in all the buckets 5 is completed, the shutter 9 is closed and drying is performed.
The movement state to the stop position P described above will be explained. When the number of buckets 5 is 14 and the number of skips is 2 (the number of skips), 1 → 4 → 7 → 10 → 13 → 2 → 5 → 8 All buckets 5 are moved to the stop position P without duplication in the order of the bucket numbers of 11 → 14 → 3 → 6 → 9 → 12.

  When the bucket 5 is moved in such an order, when the tableware is stored in each bucket 5, the tableware is automatically stored at least every three pieces, so that the occurrence of an extreme uneven load is prevented, Therefore, it is possible to easily and quickly store the tableware in a well-balanced manner and perform drying without imposing a heavy burden on the operator.

  When the drying of the tableware is completed, if the mode switch 31 switches to the automatic carry-out mode and the start switch 38 is pressed, the number of the bucket 5 at the time of storage is read from the storage unit, and the bucket 5 is in that order. Moves to the stop position and the tableware is taken out. Of course, when the tableware is taken out, the shutter 9 is opened. Therefore, even when the tableware is taken out, it is possible to prevent the occurrence of uneven load as much as possible.

  In the above-described embodiment, it has been described that the shutter 9 is opened until the work for all the tableware is completed when the tableware is stored and taken out, but only when the tableware is stored or taken out for each bucket 5. The shutter 9 may be opened and the shutter 9 may be closed while the bucket 5 is moving. At this time, when the bucket 5 is automatically moved, when the empty bucket 5 moves to the loading / unloading opening 8, the shutter 9 is automatically opened, and the operation of storing the tableware in the bucket 5 is completed. When the next operation switch 37 is pressed, the shutter 9 is automatically closed, and the next bucket 5 is moved. Of course, in this case, if the shutter 9 is not closed, an interlock is applied so that the bucket 5 is not moved.

  If the bucket 5 is to be individually moved to the stop position P in a mode other than the automatic mode, the mode is switched to the calling mode, the number setting switch 33 is pressed, and the bucket number is input by the numerical value input key unit 32. do it.

  In addition, when it is desired to move the buckets 5 upward or downward one by one, it is only necessary to switch to the single action mode and press the raising switch 35a or the lowering switch 35b of the single action switch section 35.

  Moreover, although the case where the tableware was dried was demonstrated in the said embodiment, this rotary shelf equipment is equipped with the function to perform the disinfection function, ie, the disinfection which blows a hot air for a predetermined time besides drying. In this case, instead of the above-described skip movement, the buckets 5 are moved one by one every predetermined time (for example, 5 minutes).

  By the way, the number of buckets in the above embodiment has been described as 14 that allows all the buckets 5 to move to the stop position P when the number of skips is two. If it is not possible to move all of them, the bucket 5 already filled with tableware will move to the stop position P in the middle of the movement. It is also possible to provide a bucket changing function (container changing function) that automatically moves the nearest empty bucket 5 to the stop position P. When the bucket changing function is provided, each bucket 5 is provided with a tableware detection sensor (detection means) that detects whether the bucket 5 is empty or contains tableware. The moving means 6 is controlled via the control means 7 based on the signal from the tableware detection sensor.

  Of course, to change the bucket 5 in which the tableware is stored, it is not automatically performed as described above, but a bucket changing function (container changing function) capable of manually changing the bucket 5 may be provided. Good.

  In the above embodiment, the skip number has been determined in advance. However, as shown by the wavy line in FIG. 3, a number setting switch that can arbitrarily set the skip number in the skip switch section 36. (Number setting means) 36c may be provided.

  Further, in the above embodiment, when the tableware is dried, it is described as the rotary shelf equipment that stores the tableware to be dried at one time and performs the drying. However, if necessary, a predetermined number of articles other than the tableware can be provided. The bucket can be stored or taken out.

  In this case, since the article may already be stored in the bucket that is automatically moved to the stop position every predetermined number by the skip function, as described above, the article is moved to the stop position by the article detection sensor. Whether or not the bucket has been stored is detected, and if it has been stored, the nearest empty bucket is moved or stored in the next empty bucket to be moved by the skip function.

  Further, in the above-described embodiment, the bucket has been described so as to be able to move in either the upward or downward direction (forward / reverse rotational movement). Although the loading / unloading opening is provided in one place, it can be provided in two places on the top and bottom or two places on the front wall plate and the rear wall plate, and the operation panel is operated with the operation button method instead of the touch panel method. It is also possible to adopt.
