４、(Field of Industrial Application) The present invention relates to a method for taking out molded bodies with low strength, such as crushed products of sewage sludge molten slag immediately after pressurized vibration molding for manufacturing water-permeable plates, etc., and molded bodies of foundry sand. It is something. (Prior technology) Conventionally, various types of aggregate made from crushed rocks and crushed sewage sludge molten slag are kneaded with a binder, subjected to pressure vibration molding, and this molded body is dried and fired to manufacture water permeable plates, etc. Although,
For example, the molded product obtained by kneading crushed sewage molten sludge slag with a binder and pressurized vibration molding has low shape retention and strength, so it is impossible to directly grasp the molded product and send it to the drying process. In order to avoid breaking the material, the bottom plate and rice cakes are removed from the mold and sent directly to the drying process. However, this extraction method requires an extremely large number of bottom plates, and has the disadvantage that the bottom surface of the molded product that is in close contact with the metal bottom plate is difficult to dry.For this reason, the molded product that has been removed from the mold along with the bottom plate must be manually removed. Another method is to invert the container and carefully place it on a conveyor without removing the bottom plate, but this method has the disadvantage of being inefficient because it requires manual labor. (Problems to be Solved by the Invention) The present invention solves the above-mentioned 1-1 drawback of the conventional technology, and provides a high-strength molded product that can automatically take out a low-strength molded product from a mold onto a conveyor without losing its shape. This was completed in order to provide a method for taking out molded bodies at a low cost. (Means for solving the problem) The first invention made to solve the above problem is to lift a molded body with low strength from the mold together with the bottom plate, and abut a comb-like receiving plate on the top surface of the molded body. At the same time, while chucking the bottom plate, turn the molded body upside down and place the molded body on the receiving plate, and by passing the receiving plate between the interdigitated conveyors and lowering it, only the molded body is taken out onto the conveyor. It is characterized by this. A second invention made to solve the same problem is to lift the molded body with low strength from the mold together with the bottom plate, and abut the receiving plate made of a thin plate that can be opened and closed on the upper surface of the molded body. The feature is that only the molded product is placed on the conveyor by flipping the molded product upside down while checking and placing it on the receiving plate, and then rapidly opening the receiving plate at a position directly above the conveyor. That is. These inventions will be explained in detail below with reference to illustrated embodiments. (Embodiment) FIGS. 1 and 2 show an embodiment of the first invention. In Figure 1, (1) is a molded body with poor shape retention and low strength molded inside the mold (3), and (3) is a bottom plate for molding the bottom surface of the molded body. . Reference numeral (4) is a cylinder-like bottom plate lifting mechanism, and the molded body is first lifted from the mold (2) together with the bottom plate (3) as shown in FIG. 1(A). (5) is a head for taking out the molded product, and this head (5) has a bottom plate holding arm (7) having slide chucks (6) for holding the bottom plate (3) from both sides, and a receiving plate (8).
It is equipped with In addition, a small cylinder (9) is provided at the base of these bottom plate holding arms (7), and a small cylinder (9) is provided at the base of these bottom plate holding arms (7).
) can be raised against the bottom plate holding arm (7). Such a head (5) approaches horizontally from the side in the raised molded body and holds the bottom plate (3) with the bottom plate holding arm (7).
Chuck it with the slide chuck (6). At the same time, the receiving plate (8) is brought into contact with the upper surface of the molded body by the cylinder (9). In addition, in the present invention, the receiving plate (8
) is not a flat plate, but has a comb-tooth shape as shown in No. 2 (A). After the inside of the molded body together with the bottom plate (3) is sandwiched from above and below between the bottom plate holding arm (7) and the receiving plate (8),
By inverting the head (5) about the horizontal axis 0Φ, the inside of the molded body is turned upside down. At this time, the weight of the molded body is supported by the receiving plate (8). In this state, the head (5) is moved to the side of the conveyor OD as shown in FIG. 1(B). In the present invention, the conveyor QD is also comb-shaped as shown in FIG. 2(B). Therefore, as shown in FIG. 1(B), the head (5) is moved above the conveyor (11).In the present invention, the conveyor (It) is also comb-like as shown in FIG. 2(B). It is. Therefore, Figure 1 (B
) When the receiving plate (8) is lowered by the cylinder (9), the receiving plate (8) passes through the gap in the conveyor (11) and is placed under the conveyor (11) as shown in Fig. 1 (C). The molded body is removed to the side and placed on the comb-shaped conveyor (11). At this time, the bottom plate (3) is chucked by the slide chuck (6) and is in its original position. Therefore, if the L head (5) is released in the horizontal direction as shown in FIG. 1(D), only the molded body separated from the bottom plate (3) will be taken out onto the conveyor (11). In this way, in the first invention, a comb-shaped receiving plate (8) that can pass between them and a conveyor θ1) are used, and the molded body is placed on the receiving plate (8) and then conveyed to the receiving plate. The plate (8) is passed between the conveyors Of) and only the inside of the molded body is conveyed to
Since it was made to be taken out on D, a molded body with low shape retention and strength, such as a molded body obtained by kneading crushed sewage sludge slag with a binder and pressurized vibration molding, was held from the mold, 1- and 2-2 can be automatically taken out onto the conveyor (II) without losing its shape. Note that the shapes of the receiving plate (8) and the conveyor (11) are not limited to those shown in the drawings. Furthermore, the conveyor (11) herein also includes a pedestal provided in a previous step for transferring the molded article to the conveyor. shall be. FIG. 3 shows an embodiment of the second invention. In the second invention, instead of the comb-shaped receiving plate (8), a receiving plate 02) made of a thin plate that can be opened and closed from side to side is used. , and instead of the comb-shaped conveyor (11), an ordinary conveyor is used. Also in the second invention, the upper and lower parts of the molded body are covered with receiving plates 0'.
The receiving plate 02) is sandwiched between the IJ running bottom plate holding arms (7) and turned upside down, and passes through the molded body as shown in Fig. 3 (A) and (B).
It is placed on top of the . This state corresponds to (B) in FIG. In the second invention, the receiving plate +121 is moved to a position directly above the conveyor (13) to be in the state shown in FIG. The opening/closing mechanism (opens rapidly from side to side).The opening speed at this time is, for example, 500
wn/second, and when the O force of the receiving plate is opened rapidly in this way, the molded object falls a very small distance like a "daruma drop" and is placed on the conveyor 03). Since the receiving plate surface is made of a thin plate, the falling distance in the molded product at this time is extremely small, and the molded product can be taken out onto the conveyor side without losing its shape at all. becomes. (Effects of the Invention) As explained above, according to the first and second inventions of the present application, the molded body with low strength is lifted from the mold together with the bottom plate, and a special receiving plate is brought into contact with the upper surface of the molded body. After turning the molded body upside down and placing it on the receiving plate, the V-shaped receiving plate can be passed below the conveyor, or the molded body can be taken out onto the conveyor by rapidly opening the receiving plate from side to side. can. Therefore, according to these inventions, there is no strong force, excessive force, or local force acting on the molded product, and even if the molded product has poor shape retention and low strength, it will not hold its shape at all. The molded product can be automatically taken out onto the conveyor without fear of collapse.Therefore, according to the present invention, there is no need to send the molded product together with the bottom plate to the drying process as in the conventional method, and there is no need to manually take out the molded product. Therefore, the present invention greatly contributes to the development of industry by providing a method for removing molded bodies with low strength that eliminates the conventional problems.4.
