Furthermore, in this embodiment, the articles 9 are of an aluminum mold type placed on a pallet with sockets 8 embedded in the bottom surface, but all the articles are stored in the article storage section 12 provided with pipe joints. In the present invention, it is an article. For example, a pallet provided with pipe fittings is an article.

Next, a description will be given of a manner in which fluid is supplied to articles by using the storage equipment of the embodiment configured as described above in the foaming process of a urethane sheet manufacturing line.

As part of the urethane sheet manufacturing line, the storage equipment of this example is to heat an aluminum mold injected with urethane raw material with steam for a desired period of time to foam the urethane, and to store aluminum molds into which urethane raw material has not been injected. It stores and preheats molds, manages the storage position of articles, heating time, etc., and sends and receives signals to operate the rotary shelf unit 11, warehousing device 2, unloading device 3, transfer device 4, etc. A management computer (CPU) that performs the following operations, and a management computer (CPU) that controls the rotation direction, stop position, etc. for each rotating shelf 11 according to the signals, and also controls the storage input device 2 and the storage output device 3.
is connected to a drive control device that performs drive control such as the stop position of the aluminum mold mold, that is, when the product 9 is supplied to the rotating shelf, the data related to the product 9 is used for management purposes. Since it is configured to be input to the computer (CPU),
Based on the data, the article 9 can be appropriately heated with steam or the like.

When the article 9 arrives at the entrance of the carry-in conveyor 22, the management computer (CPU) records the above-mentioned data such as the number of the aluminum mold, whether urethane raw material is injected into the aluminum mold, and the like.
If it is being injected, receive the steam heating time.

To explain in detail the case where the article 9 in which the urethane raw material is injected is supplied, among the four stages of rotating shelves 11, the lower two stages are used for steam heating, and the upper two stages are used for storage and preheating. In this embodiment, the steam heating time for the article 9 is divided into three types: 4 minutes, 5 minutes, and 6 minutes, so the steam heating time for the rotary shelf 11 in the first stage from the bottom is 4 minutes. The rotary shelf 11 on the second stage is exclusively used for articles 9 whose steam heating time is 5 minutes and 6 minutes.
It is also used as a. As shown in FIGS. 1 and 2, the article 9 whose steam heating time is 4 minutes is conveyed to the article storage section 12 via the carry-in conveyor 22 and the supply conveyor 23, and is placed at the tip of the supply conveyor 23. At the same time, the pipe joint consisting of the plug 7 and the socket 8 is opened, and the steam supplied via the fluid distribution device 5 is lowered by the lifted lift mechanism and placed on the article storage section 12. is supplied to start heating. Also, the steam heating time is 5
As shown in FIGS. 1 and 3, the minute or six minute articles 9 are transported to the article storage section 12 via the carry-in conveyor 22, the first-stage supply conveyor 23, the tray conveyor 21, and the second-stage supply conveyor 23. The heating by steam is started in the same way as when steam is supplied to the first stage.

That is, in the pipe joint composed of the plug 7 and the socket 8, the tip of the plug 7 is protected by the protruding body 73, and the plug 7 and the socket 8 are protected by the protruding body 73 and the fitting body 83. are guided and connected so that they are roughly aligned. In addition, plug 7
Final alignment between the plug 7 and the socket 8 is achieved by deforming the support spring 74 so that the axial center line of the plug 7 coincides with the axial center line of the socket 8. The support spring 74 also has the effect of keeping the pressing force between the plug 7 and the socket 8 constant. When the plug 7 and the socket 8 are connected, the respective valve bodies 72,
82 is opened and steam is supplied to article 9 as described above.

After the articles 9 stored in the article storage section 12 are heated with steam for a certain period of time, the articles 9 stored in the first stage are conveyed to the next process via the discharge conveyor 33 and the carry-out conveyor 32. Moreover, the articles 9 stored in the second stage are transferred to the second stage discharge conveyor 33, the tray conveyor 31, the first stage discharge conveyor 33, and the discharge conveyor 3.
2 to the next process. In addition, the articles 9 stored in the second stage are transported to the second stage discharge conveyor 2.
3. The tray conveyor 31, the first stage discharge conveyor 33, and the discharge conveyor 32 are conveyed to the next process.

The rotary shelf 11 at the bottom is configured to rotate counterclockwise by 1 pitch every 14 seconds, and the article 9 is discharged (taken out) at the 17th pitch from the position where it was supplied (received).
Therefore, the article 9 will be discharged (taken out of the warehouse) after being steam-heated for 4 minutes. In addition, the second stage rotating shelf 11 rotates once every 24 seconds.
The item 9 is configured to rotate counterclockwise in pitches, and the article 9 is discharged (taken out) at the 15th pitch from the position where it was supplied (received), so the article 9 is steam-heated for 6 minutes before being discharged ( will be shipped). However, if the article 9 whose steam heating time is 5 minutes is supplied (received) to the second stage carousel 11, the article 9 will move to the 12th pitch (approximately 4 minutes and 48 seconds have passed since the supply). ), the second-stage carousel 11 rotates to the position (15th pitch) where the article 9 faces the discharge conveyor 33, and after discharging (taking out) the article 9, the carousel 11 moves to the position where the article 9 faces the discharge conveyor 33. It is controlled to return to the correct position. That is, the steam heating time of the articles 9 sequentially supplied (in stock) to the carousel 11 is individually controlled, and the articles 9 are discharged (out of stock) after a predetermined time has elapsed. When used in the urethane foaming process, when the supply (warehousing) command and the discharge (warehousing) command of the article 9 conflict, it is preferable to control the supply (warehousing) command so as to take priority. That is, it is preferable to eliminate the waiting time for the articles 9 to be supplied (warehoused), and to perform control so that the discharge (output) of the articles 9 is slightly delayed (the steam heating time is slightly longer).

Further, the articles 9 stored in the upper two tiers of the rotating shelves 11 are transferred to the lower two tiers of the rotating shelves 11 by the transfer device 4. In addition, the lower two levels of rotating shelves 1
1 is transferred to the upper two rotating shelves 11 by the transfer device 4. That is, the articles 9 to which urethane raw materials have not been injected are stored in the upper two rotating shelves 11 for storage, and when a discharge (retrieval) command is issued for these articles 9, the transfer device 4,
It is discharged (taken out) via the single rotating shelf 11 of the lower two tiers. Note that the discharge (dispatch) command includes the aluminum mold mold number and preheating time, and the articles 9 to be discharged (dispatch) are preheated for a predetermined time on the upper two rotating shelves 11 before being discharged. (out of stock).

Although the embodiments of the storage equipment of the present invention and the mode of supplying fluid to articles using the storage equipment of the present invention have been described above, the present invention is not limited to these examples. A socket 8 may be provided in the article storage section 12. In addition, the protruding body 73, the fitting body 83, the support spring 7
4 etc. are not essential, and may be provided as appropriate. Further, the fluid is not limited to steam, and may be cooling water, compressed air, or the like.

(Effects of the Invention) As described above, the storage equipment of the present invention is provided with a pipe joint on the outside of the article, and a pipe joint that can be connected to and separated from the pipe joint is provided in the article storage section. It can supply fluid to stored items, and has extremely high industrial utility value as aging equipment, etc.
