Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention has low strength such as a crushed product of sewage sludge molten slag immediately after pressure vibration molding for manufacturing a water permeable plate and a molded product of foundry sand. The present invention relates to a method for taking out a molded body.

(Prior Art) Conventionally, various aggregates obtained by crushing rock and crushed materials of sewage sludge molten slag are kneaded with a binder, pressure vibration molded, and the molded body is dried and fired to produce a water-permeable plate. However,
For example, a crushed product of sewage-melted sludge slag is kneaded with a binder, and the molded product obtained by pressure vibration molding has low shape retention and strength, so the molded product cannot be directly grabbed and sent to the drying process. The bottom plate and the bottom plate are removed from the mold so that they do not break, and they are sent to the drying process as they are. However, such a take-out method requires a very large number of bottom plates, and has the drawback that the bottom surface of the molded body that is in close contact with the metal bottom plate is difficult to dry.

For this reason, a method of manually inverting the molded body that has been removed from the mold together with the bottom plate and carefully placing it on the conveyor and removing the bottom plate is also performed, but this method has the drawback of being inefficient because it relies on manual labor.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the related art, and allows molding of a low-strength molded article to be automatically taken out from a molding die onto a conveyor without losing its shape. It has been completed to provide a method of body removal.

(Means for Solving the Problems) The first invention made to solve the above problems is to lift a molded body having low strength together with a bottom plate from a molding die, and contact a comb-shaped receiving plate on the upper surface thereof. While chucking the bottom plate, turn the molded product upside down and place the molded product on the receiving plate, and pass the receiving plate between the comb-shaped conveyors and lower it to take out only the molded product onto the conveyor. It is characterized by that.

A second occurrence made to solve the same problem is to lift a molded body having low strength together with a bottom plate from a molding die, bring a top plate into contact with a receiving plate made of a thin plate, and chuck the bottom plate. While the molded body is turned upside down, the molded body is placed on the receiving plate, and the receiving plate is rapidly opened at a position directly above the conveyor so that only the molded body is placed on the conveyor. .

Hereinafter, these inventions will be described in detail with reference to illustrated embodiments.

(Embodiment) FIG. 1 and FIG. 2 show an embodiment of the first invention.

In FIG. 1, (1) is a molded body formed inside the molding die (3) with poor shape retention and low strength, and (3) is a bottom plate for molding the bottom surface of the molded body (1). Is. (4) is a bottom plate lifting mechanism like a cylinder. First, the molded body (1) is shown in Fig. 1 (A).
Like the bottom plate (3), it is lifted from the mold (2).

(5) is a head for taking out the molded body, and this head (5)
Is a slide chuck for holding the bottom plate (3) from both sides.
It has a bottom plate holding arm (7) having (6) and a receiving plate (8).
A small cylinder is attached to the base of these bottom plate holding arms (7).
(9) is provided, and the receiving plate (8) can be moved up and down with respect to the bottom plate holding arm (7). Such a head (5) approaches horizontally from the side of the lifted compact (1),
(3) is chucked by the slide chuck (6) of the bottom plate holding arm (7). Along with this, the cylinder (9) supports
The (8) is brought into contact with the upper surface of the molded body (1). In the present invention, the backing plate (8) is not a flat plate but a tooth-like shape as shown in FIG. 2 (A).

In this way, the molded body (1) is attached to the bottom plate holding arm together with the bottom plate (3).
After sandwiching it from above and below with (7) and backing plate (8),
The head (5) is inverted about 0) to invert the molded body (1) upside down. At this time, the weight of the molded body (1) is in a state of being supported by the receiving plate (8). First in this state
Move the head (5) above the conveyor (11) as shown in Figure (B).

In the present invention, the conveyor (11) also has a tooth-like shape as shown in FIG. 2 (B). Therefore, as shown in FIG. 1 (B), the head (5) is moved to above the conveyor (11).

In the present invention, the conveyor (11) also has a tooth-like shape as shown in FIG. 2 (B). Therefore, when the backing plate (8) is lowered by the cylinder (9) from the state shown in Fig. 1 (B), the backing plate
(8) passes through the gap of the conveyor (11) and escapes to the lower side of the conveyor (11) as shown in Fig. 1 (C), and only the molded body (1) is on the comb-shaped conveyor (11). Be listed. At this time, the bottom plate (3) is chucked by the slide chuck (6) and is in its original position. Therefore, if the head (5) is allowed to escape horizontally as shown in Fig. 1 (D), only the molded body (1) separated from the bottom plate (3) is conveyed (1).
1) Will be taken over.

As described above, in the first aspect of the present invention, the molded body (1) is formed by using the comb-shaped receiving plate (8) and the conveyor (11) that can pass through each other.
After placing the base plate on the backing plate (8), the backing plate (8) is passed between the conveyors (11) and only the molded body (1) is taken out onto the conveyor (11). A compact having low shape retention and strength such as the compact (1) obtained by kneading the pulverized product of (1) with a binder and pressurizing vibration molding is lifted from the mold and the conveyor (11) ) Can be taken out automatically. The shapes of the receiving plate (8) and the conveyor (11) are not limited to those shown in the figure. Further, the conveyor (11) referred to here also includes a pedestal provided in the preceding step for transferring the molded body (1) to the conveyor.

FIG. 3 shows an embodiment of the second invention.

In the second aspect of the invention, instead of the comb-shaped receiving plate (8), a receiving plate (12) made of a thin plate that can be opened and closed to the left and right is used, and in place of the comb-shaped conveyor (11), it is normally formed. Conveyor
(13) is used.

Also in the second invention, the molded body (1) has the upper and lower support plates (1
It is sandwiched between 2) and the bottom plate holding arm (7) and turned upside down.
As shown in Figures (A) and (B), the molded body (1) is placed on the backing plate (12). This state corresponds to (B) in FIG. However, in the second aspect of the invention, the receiving plate (12) is moved to a position directly above the conveyor (13) so as to be in the state of FIG. 3 (C), and then the receiving plate (12) is incorporated into the head (5). It opens rapidly to the left and right by the open / close mechanism. The opening degree at this time is, for example, 500 mm / sec, and when the backing plate (12) is rapidly opened in this way, the molded body (1) falls a minute distance as it is, such as "Dharma drop", and the conveyor is moved. (13) Will be listed above. Since the backing plate (12) is a thin plate, the drop distance of the molded body (1) at this time is very small, and the molded body (1) will be taken out onto the conveyor (13) without any deformation. .

(Effects of the Invention) As described above, according to the first and second inventions of the present application, the molded body having low strength is lifted together with the bottom plate from the molding die, and the special receiving plate is brought into contact with the upper surface thereof to raise and lower It is possible to take out the molded product onto the conveyor by reversing and placing the molded product on the receiving plate and then passing the receiving plate below the conveyor, or by rapidly opening the receiving plate left and right. Therefore, according to these inventions, a strong force, an unreasonable force, or a local force does not act on the molded body at all, and even if the molded body has poor shape retention and low strength, the molded body does not have any shape. It can be automatically taken out on the conveyor without fear of collapse. Therefore, according to the present invention, it is not necessary to send the molded product together with the bottom plate to the drying step as in the prior art, and it is not necessary to manually remove the molded product.

Therefore, the present invention, as a method for taking out a molded product having a low strength that eliminates the conventional problems, has an extremely great contribution to the industrial development.
