Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block body forming apparatus capable of efficiently forming a block body such as a water permeable block from a granular raw material such as molten slag of sewage sludge incineration ash.

[0002]

2. Description of the Related Art In order to effectively utilize the sewage sludge incineration ash generated from a sewage treatment plant, etc., the sludge incineration ash is made into molten slag, which is molded into a block shape with an inorganic binder and fired to obtain a water permeability for paving. Attempts have been made to sex blocks. However, since the unfired block body formed from such a granular raw material has low strength, it cannot be taken out from the mold as it is. For this purpose, the conventionally molded block body is pushed up together with the bottom plate from the inside of the mold, a flat plate is applied to the upper surface of the block body, the block plate is lightly sandwiched between the bottom plate and this flat plate, and the block body is flipped upside down. The method is taken out with the bottom plate attached.

However, when such a molding method is adopted, it is necessary to separate the bottom plate from the block body taken out on the conveyor and return it again into the mold of the molding machine, and therefore the first molding is completed. Since a considerable interval was required from the second molding to the second molding, the molding speed could not be improved.

As shown in FIG. 4, this head 12 has a fork 13 on the lower side thereof, which is inserted into the lower surface of the bottom plate 3 pushed up from the molding die 1, and contacts the upper surface of the molded block body B on the upper side. A support 15 for the flat plate 14 is provided. The support 15 for the flat plate 14 can be moved closer to and away from the fork 13 by a small cylinder 16. The support 15 for the fork 13 and the flat plate 14 is provided with opening and closing claws 17 and 18 that can hold the bottom plate 3 and the flat plate 14 from both sides by a mechanism (not shown).

As shown in FIG. 1, in the reversing and taking-out mechanism 7, the flat plate 14 is brought into close contact with the upper surface of the block body B which is pushed upward from the molding die 1 together with the bottom plate 3 so that the block body B is provided between the block body B and the bottom plate 3. Lightly pinch, hydraulic torque actuator
The bottom plate 3 is turned upside down by 11 and is taken out onto the conveyor 6 with the bottom plate 3 facing upward. At this time, the open / close claws 18 of the flat plate 14 are opened, but the open / close claws 17 of the bottom plate 3 are kept closed. Therefore, as shown by the phantom line in FIG.
The bottom plate 3 is taken out onto the conveyor 6 while being placed on the
Remains held by the opening / closing claw 17.

As shown in FIG. 1, the bottom plate returning mechanism 19 receives the bottom plate 3 from the reversal take-out mechanism 7 on the lower side of the molding die 1, travels on the rail 20 and returns it to the inside of the molding die 1.
Is provided. As shown in FIG. 5, the bottom plate returning mechanism 19 includes a frame 21, a cylinder 22 and an arm 23 for causing the frame 21 to travel along the rail 20. The frame 21 is divided into two, and a small cylinder for moving the bottom plate 3 up and down is provided on the upper surface of each frame 21.
Three 24 are provided.

A bottom plate support plate 26 that is moved up and down by a cylinder 25 is provided directly below the rail 20. As shown in FIG. 5, this has a role of placing the bottom plate 3 held by the opening / closing claws 17 of the reversal take-out mechanism 7 on the frame 21 by moving up and down at the center of the frame 21 separated into two. .

Next, the operation of the above device will be described. First, when the molding is completed in the molding die 1, the bottom plate 3 is formed together with the block body B molded by the bottom plate push-up rod 5.

Next, the inversion take-out mechanism 7 makes the flat plate 14 adhere to the upper surface of the block body B, and the fork 1311 is inserted into the lower surface of the bottom plate 3 to lightly sandwich the block body B between the bottom plate 3 and the hydraulic torque actuator 11.
The block body B formed with the bottom plate 3 facing upward is taken out onto the conveyor 8 while being turned upside down. At this time, as described above, the opening / closing claw 18 of the flat plate 14 is opened, but the opening / closing claw 17 of the bottom plate 3 is kept closed. Therefore, the block body B is taken out onto the conveyor 6 while being placed on the flat plate 14. As a result, the bottom plate 3 remains held by the opening / closing claw 17 of the reversal take-out mechanism 7.

Next, the reversal take-out mechanism 7 returns the head 12 holding the bottom plate 3 to the position directly above the bottom plate support plate 26 while reversing the head 12 by 180 degrees, and the bottom plate support plate 26 is lifted by the cylinder 25 to receive the bottom plate 3. In this state, the opening / closing claw 17 of the reversal take-out mechanism 7 opens, and the bottom plate 3 moves from the reversal take-out mechanism 7 onto the bottom plate support plate 26. Next, the bottom plate support plate 26 descends to move the bottom plate 3
Is supported on the tip of the small cylinder 24 of the bottom plate returning mechanism 19.

Next, the small cylinder 24 of the bottom plate returning mechanism 19 slightly lifts the bottom plate 3 from the bottom plate supporting plate 26, and the arm 23 is rotated by the cylinder 22 to form the bottom plate returning mechanism 19 in the molding die 1.
Move down. At this time, the bottom plate 3 is in a state in which both sides are supported by the frame 21 which is separated into two parts.
The bottom plate push-up bar 5 is lowered to the lowest position. Then, when the bottom plate push-up bar 5 is raised, the bottom plate 3 on the frame 21 returns to the inside of the mold 1 from below the mold 1, and the next molding is performed.

As described above, in the first aspect of the invention, the bottom plate 3 returns to the inside of the molding die 1 from below the molding die 1. If a part of the granular raw material from the previous molding adheres to the side surface of the molding die 1. If left as it is, the quality of the block body B to be molded next time is deteriorated. Therefore, as shown in FIG. 7 or FIG.
A brush 30, a rubber packing, or the like is attached to the outer periphery of the bottom surface of the bottom plate or around the bottom plate push-up rod 5, and the brush 30 or the like is formed when the bottom plate 3 is pushed up from the molding die 1 and when the bottom plate push-up rod 5 is lowered again. It is preferable to have a structure for cleaning the side surface of the mold 1.

As described above, according to the first aspect of the invention, the bottom plate 3 taken out together with the block body B can be automatically returned to the inside of the molding die 1 from the lower side of the molding die 1. As compared with the conventional method in which the worker returns the bottom plate 3 to the inside of the molding die 1 from above the conveyor, the molding speed can be greatly improved.

FIG. 6 shows an embodiment of the second invention, in which the reversal take-out mechanism 7 is the same as that of the first invention,
The bottom plate returning mechanism 19 is provided on the side of the molding die 1, and the bottom plate returning mechanism 19 receives the bottom plate 3 from the reversal take-out mechanism 7 and returns it from the upper side of the molding die 1 to the inside of the molding die 1. Is different. In the second invention, since the returned bottom plate 3 descends inside the molding die 1, there is an advantage that the side surface of the molding die 1 is cleaned by the side surface of the bottom plate 3, and in particular, as shown in FIG. If a brush 30, a rubber packing or the like is attached around the lower surface of 3, the effect can be enhanced.
