Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded product takeout device for taking out a low-strength molded product from a press molding machine onto a conveyor, such as a molded product obtained by press-molding a crushed product of sewage sludge molten slag. It is a thing.

[0002]

2. Description of the Related Art In order to effectively utilize a large amount of sewage sludge generated from a sewage treatment plant or the like, the present inventors are developing a method for producing a water-permeable block using sewage sludge as a raw material. The method of manufacturing the water permeable block is that the sewage sludge is first used as a molten slag, and the block is formed by using a granular material obtained by crushing the sludge as a raw material and firing. However, since this molded product has low strength before firing, it loses its shape when gripped by a chuck and cannot be taken out from the molding machine properly. For this reason, the present inventor has developed a technique for taking out the molded product while reversing it by sandwiching the upper and lower surfaces with a flat plate, and has already applied for a patent as Japanese Patent Application No. 2-185728.

The method of this prior application is excellent in that a molded product having a low strength can be taken out from a molding machine onto a conveyor without losing its shape. However, the bottom plate needs to be moved up and down inside the molding die, which causes problems such as troubles due to spilled raw materials and a complicated inversion mechanism.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and allows a molded low-strength molded product to be taken out from a molding machine without losing its shape, causing troubles due to spilled raw materials. The present invention has been completed in order to provide a device for taking out a molded body that is not likely to occur and does not require a complicated inversion mechanism.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a comb-tooth conveyor having a plurality of conveyor belts protruding in a comb-tooth shape on the side of a press molding machine. At the same time, a carriage that can reciprocate between the press molding machine and the comb tooth conveyor is provided below the comb tooth conveyor, and inside the groove formed in the lower die of the press molding machine on this carriage.
The upper surface of the arm is inserted to form a part of the lower mold surface.
The gist of the present invention is a device for taking out a molded body, which is characterized in that a comb-shaped arm capable of performing molding and lifting the molded body after the molding is attached so as to be able to move up and down.

[0006]

The present invention will be described below in more detail with reference to the illustrated embodiments. In FIG. 1, 1 is a press molding machine, which is provided with a frame-shaped side mold 4 between an upper mold 2 and a lower mold 3,
A raw material such as a crushed sewage sludge molten slag is press-molded inside the side mold 4. As shown in FIG. 3, a plurality of grooves 5 are formed in the lower mold 3, and the comb-shaped arms 6 are exactly inserted into the grooves 5, and the upper surfaces of the arms 6 are Molding is performed in a state of forming a part of the lower mold surface .

Reference numeral 7 denotes a comb tooth conveyor provided on the side of the press molding machine 1. This comb-tooth conveyor 7 has a plurality of conveyor belts 9 supported by a thin bar 8,
By attaching the bases of these thin bars 8 to a base (not shown), a plurality of conveyor belts 9 are made to protrude like comb teeth. The intervals between the plurality of conveyor belts 9 are set so that the comb-shaped arms 6 can be projected and retracted between them.

Below the comb tooth conveyor 7, a rail 10 is provided.
Are laid, and a truck 11 is installed on this rail 10. The carriage 11 can be reciprocated between a position on the press molding machine 1 side indicated by the solid line in FIG. 1 and a position on the comb tooth conveyor 7 side indicated by the chain line in FIG. 1 by an appropriate drive mechanism. An elevating table 12 is mounted on the dolly 11, and the comb-teeth-shaped arm 6 is mounted on the upper end of the elevating table 12.
The base of is supported.

[0009]

The operation of the molded product take-out apparatus of the present invention is as follows. First, as shown by the solid line in FIG. 1, the carriage 11 is a rail.
10 Move to the press molding machine 1 side, and comb-shaped arm 6
Is inserted into the plurality of grooves 5 formed in the lower mold 3 of the press molding machine 1, and the upper surface of the arm 6 constitutes a part of the lower mold surface.
To do so. Even if the raw material is spilled into the groove 5 at this time, it is pushed out from the end of the groove 5 by the tip of the arm 6. In this state, the frame-shaped side die 4 is lowered onto the lower die 3, the raw material is supplied into the side die 4, and press molding by the upper die 2 is performed as in the conventional case.

After the molded body W is obtained in this manner, when the side mold 4 is lifted, the molded body W remains on the lower mold 3. Therefore, when the lift 12 of the carriage 11 is slightly lifted to raise the comb-tooth-shaped arm 6 from the groove 5 of the lower die 3, the compact W is gently lifted from above the lower die 3 by the comb-tooth-shaped arm 6. Becomes As described above, the molded body W has a low strength, but according to this method, it can be lifted without losing its shape.

Next, the carriage 11 moves on the rail 10 and the comb tooth conveyor 7
Move to the side. Along with this, the molded body W supported by the comb-tooth-shaped arm 6 also moves to the comb-tooth conveyor 7 side, and the comb-tooth-shaped arm 6 enters between the plurality of conveyor belts 9 of the comb-tooth conveyor 7. The molded body W is moved to just above the comb tooth conveyor 7. Then, when the elevator 12 of the carriage 11 is slightly lowered to lower the comb-teeth-shaped arm 6 below the upper surface of the conveyor belt 9, the compact W is placed on the conveyor belt 9 of the comb-teeth conveyor 7. Also at this time, there is no possibility that the molded body W will lose its shape. After that, the truck 11 is a rail
The upper part is moved to the press molding machine 1 side, and the same steps are repeated thereafter.

[0012]

As described above, according to the molded product take-out apparatus of the present invention, a low-strength molded product such as a molded product obtained by press-molding a sewage sludge molten slag crushed product is molded from a molding machine. It can be taken out without breaking. In addition, the apparatus for taking out a molded product of the present invention has an advantage that a complicated inversion mechanism as in the prior art is not required and that there is no fear of trouble due to spilled raw material. Therefore, the present invention has a great contribution to the industrial development as a molded product take-out device which solves the conventional problems.
