〔Example〕

FIG. 1 shows the layout of an automatic processing apparatus for molded articles according to the present invention. A is a compression molding machine for materials such as cementitious materials and ceramic compositions. For example, a vacuum suction type compression molding machine as described in Japanese Patent Publication No. 54-20209 can be used. The molded product manufactured by the machine A is placed on the pallet and sent to the carry-in station C by the conveying device B composed of two cord belts, and the molded product placed on the pallet is inserted into the carry-in station C. As a result, the molded product that has been carried into the predetermined storage hole of the multi-row / multi-stage mobile storage rack F and that has already been subjected to the curing treatment and is located in the predetermined storage hole of the multi-row / multi-stage mobile storage rack F is carried out at the unloading station D. From the carry-out station D side to the molded product take-out section G by the carrying device E composed of two cord-shaped belts.
The molded product is separated from the pallet at the molded product unloading section G and sent to the molded product unloading side. The pallet is sent to the automatic compression molding machine A side by the carrying device H.

J ₁ is a curing room located in front of the carry-in station C and carry-out station D to cure the molded product in the moving storage rack F, and J ₂ is located behind the carry-in station C and carry-out station D. However, like the curing room J ₁ , it is a room in which the molded product in the moving storage rack F can be cured. When the moving storage rack F moves from the front curing room J ₁ to the rear curing room J ₂ , it moves. As shown in FIG. 1, the tip of the storage rack F is located at a position corresponding to the loading / unloading station.

The present invention uses a multi-row / multi-stage mobile storage rack F. The multi-row / multi-stage mobile storage rack F stores uncured molded products at the loading / unloading stations C and D and is simultaneously cured. The molded product is discharged, and the relationship between the molded product stored in the movable storage rack F and the curing will be described.

The movable storage rack F located at the positions shown in FIGS. 1 and 2 stores molded products, for example, in the order from the bottom to the top.
After the storage of the molded products in f ₁ , the storage rack F is moved on the track 1 by the distance of one row, and the molded products are stored in the second row f ₂ from the uppermost stage to the lower storage space. The distance of one row of the shelf F is driven. At this time, the molded products are sequentially sent to the front curing room J ₁ from the front end row f ₁ of the moving storage rack F. When the storage of the molded product in the rear end row f _{n of} the moving storage rack F is finished, the moving storage rack F is sent to the front curing room J ₁ .

An example in which the time required for loading and unloading of the molded product from all of the front end row f ₁ to the rear end row f _n of the movable storage rack F is two in one row and 26 rows in one row in the vertical direction, which is 20 rows. In the case of the moving storage rack F, it takes a considerable amount of time even if it is automatically loaded and unloaded, and the moving storage rack F is moved and stored even after the curing of the molded product on the front end row f ₁ side of the moving storage rack F. In many cases, the molded product on the rear end row f _n side of the shelf F is not sufficiently cured.

According to the present invention, as soon as the molding of the front end row f ₁ of the moving storage rack F is completed, the moving storage rack F is immediately retracted to the positions shown in FIGS. The rear end row f _n side of the moving storage rack F that accommodates the row f ₁ at the loading / unloading stations C and D and stores the uncured molded product is located in the rear curing room J ₂ .

Therefore, in the loading / unloading stations C and D, while carrying in / out the molded product from the front end row f _{1 of} the moving storage rack F, the moving storage rack F is sequentially driven forward intermittently as described above. Meanwhile, the rear end row f _n side of the moving storage rack F is located in the rear curing room J ₂ , and the time when the front end row f ₁ of the moving storage rack F stays in the front curing room J ₁ and its rear end row f _n Stay in the curing room J ₁ and the rearward curing room J ₂ for the same time, and the molded product of the movable storage rack F having a certain size can give uniform curing at all positions.

Each of the carry-in station C and the carry-out station D is provided with a base frame 2 for sequentially carrying in and carrying out a molded product to and from the upper and lower stages of the moving storage rack F. A molded product placed on a pallet from the side of the machine A is fed through the carrying device B, and from the base frame 2 to the carrying device E.
The molded product is sent to the molded product unloading section G via.

As shown in FIG. 2, the conveying devices B and E of the embodiment move up and down on the side of the molding machine A, which is one end thereof, and the shaft 3 on the side of the molded product unloading part G, and the base frame 2 side of the other end. The transport path is configured so as to be capable.

In the mobile storage rack F, wheels 6 are provided on a plurality of axles 5 on a dolly 4, and drive motors are arranged on the appropriate number of the axles 5,
In the carry-in station C and the carry-out station D, when the molded articles are stored and discharged in the upper and lower stages, the movable storage rack F is driven on the track 1 by a distance corresponding to one row, and the track 1 is
It is laid from the rear end of the rear curing chamber J ₂ between the molding machine A and the molded product unloading section G to the inside of the front end of the front curing chamber J ₁ .

Therefore, the uncured molded product is stored from the molding machine A to the transfer device B from the transfer device B to the movable storage rack F from the vertically movable base frame 2 and is connected to the front curing chamber J ₁ or the front curing chamber J ₁ . A prescribed curing is performed in the rear curing chamber J ₂ , and the next uncured molded product is inserted and sent out to the base frame 2 ′ of the carry-out station D. In the molded product take-out section G, the molded product is separated from the pallet by the suction means 7 and taken out onto the molded product carrying path 8, while the carrying device H sends the pallet to the molding machine A side.

[Effect]

According to the configuration of the present invention, since the curing treatment is performed by using the multi-row / multi-stage moving storage rack, it takes a considerable time to carry in / out all the molded articles to / from this moving storage rack, and By providing a curing room in the front and back, the entire time required for loading and unloading can be used for the curing time, and therefore, the cycle of loading and unloading molded articles to and from the mobile storage rack can be shortened. Therefore, it is possible to improve the production efficiency, and it is possible to always give a certain curing time to the molded products in the front and rear parts of the moving storage rack, and to obtain a molded product of constant quality. Bring in a curing room
Even if it is provided before and after the carry-out station, the space required for advancing / retracting the moving storage rack is used, and therefore there is an advantage that no special space is required.
