DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a connecting block laid on a sidewalk or the like and an apparatus for manufacturing a connecting block.

[0002]

2. Description of the Related Art Conventionally, as a block laid on a sidewalk or a park, a connecting block in which a plurality of blocks are connected by a flexible connecting member has been used. According to this connecting block, a plurality of blocks can be laid at one time, and work efficiency can be improved.
Then, such a connecting block is supplied with a highly fluid member (for example, cement milk) in the same form in a state where the connecting member is disposed in the form, and then left as it is to be dried and hardened. It is manufactured by a so-called casting method.

[0003]

However, in the above-mentioned casting method, although the internal structure of the completed block can be made dense due to the high fluidity of the raw material, it takes time until the raw material poured into the mold is dried and hardened. There was a problem that it took. Further, when a large number of connecting blocks are to be manufactured in one day, a mold for the number of units of the connecting blocks to be molded is required, which increases the manufacturing cost and is extremely poor in manufacturing efficiency. was there.

On the other hand, when manufacturing a normal block,
Conventionally, a pressure molding method has been widely used. In this pressure molding method, after supplying a raw material having a relatively low fluidity (for example, a mortar of zero slump) to the raw material used in the casting method in a mold, the filled raw material is added to the raw material. This is a method in which pressure molding is performed and the molding is immediately solidified. Therefore, in the case of the pressure molding method, since the fluidity of the raw material is relatively low, there is a shape retaining force that does not collapse even if the mold is immediately removed after the pressure molding, and one mold is used. Therefore, there is an advantage that a large number of blocks can be continuously formed. However, in the above-mentioned connecting block, a manufacturing method by a pressure molding method has not been established, and no manufacturing apparatus exists. Therefore, the connecting block was not manufactured at all by the pressure molding method, but had to be manufactured by the casting method.

The present invention has been made in view of such problems existing in the prior art, and an object of the present invention is to enable a connecting block to be easily, quickly and efficiently manufactured by a pressure molding method. An object of the present invention is to provide a method of manufacturing a connecting block and a manufacturing apparatus thereof.

In this embodiment, the case where one connecting block 10 shown in FIG. 1 is manufactured is described. Also, in FIGS. 5 to 6 and FIG. 10, the pressing mold 54 is omitted for simplification.

First, as shown in FIG.
7. The supply device 42 and the clamp device 47 are moved to the positions at the time of each transfer. Then, the pallet 39 supplied from the loading device 40 is placed on the lifting table 37 by a pusher (not shown). After the pallet 39 is supplied, a new pallet 39 is on standby on the carry-in device 40 to manufacture the next connection block 10. Then, the connection member 20 is supplied from the supply device 42, and one end side (front end side) thereof is gripped and fixed by the clamp member 52 of the clamp device 47 as shown in FIG. At this time, the vibration generating device 36 is not operating, and thus the
Is not vibrating. Further, both supply boxes 25 and 27 are also waiting at the lower positions of the respective supply boxes 24 and 26.

Next, as shown in FIG.
0 in a horizontal state, the feeding device 4 is synchronized with the upward movement of the elevating table 37 to the position at the time of molding.
2 and the clamp device 47 are moved up to the position at the time of each molding. Then, the pallet 39 is brought into close contact with the lower side of the formwork 28 as shown in FIG. At this time, the net-shaped connecting member 20 is connected to the supply device 42 and the clamp device 47.
As a result of the synchronous movement of the mold 28, it moves upward while maintaining the horizontal state, and is inserted into the vertical insertion groove 34A and the horizontal insertion groove 35B formed in the formwork 28. Therefore, the connecting member 20 is arranged in the formwork 28, and when the material is supplied into the formwork 28 in the subsequent steps, the connecting member 20 is partially buried with the raw material. Will be.

Next, from the state shown in FIG. 6, the base material supply box 25, to which the base material has been supplied by the base material supply box 24, is moved forward to a position above the formwork 28 by a moving device (not shown). The material is started. And with the start of feeding,
The vibration generating device 36 is operated, and vibration is applied to the formwork 28 via the lifting table 37. Then, the supplied raw material becomes dense in the formwork 28 due to the vibration. The vibration by the vibration generating device 36 is continuously performed in the subsequent steps until the pressure is formed by the pressing mold 54 described later. When a predetermined amount of material is supplied from the base material supply box 25 and the supply for the base material 21 of the small blocks 11 to 19 is completed, the base material supply box 25 is moved by the moving device (not shown) to the base material supply box 25. It moves backward to the lower position of the material supply box 24.

Then, the surface material supply box 27 to which the raw material has been supplied by the surface material supply box 26 is moved forward to a position above the formwork 28 by a moving device (not shown), and the material supply is started. . When a predetermined amount of material is supplied from the surface material box 27 and the material supply for the surface layer 22 of the small blocks 11 to 19 is completed, the surface material box 27 is moved by the moving device (not shown) to the surface material box. It moves backward to the lower position of the material supply box 26.

Next, as shown in FIG. 7, the pressing mold 54 is moved downward after being positioned at the upper position of the mold frame 28 by a moving device (not shown), and the raw material filled in the mold frame 28 is pressure-formed. I do. Then, after a certain amount of pressure is applied by the pressing mold 54, the vibration by the vibration generator 36 is stopped. The pressing amount of the pressing mold 54 into the raw material is 1
It is about 0 to 20 mm. In addition, at the time of pressure molding by the pressing mold 54, a pattern is formed on the surfaces 11a to 19a of the small blocks 11 to 19 by the design surface.

Next, as shown in FIG.
When the supply device 42 and the clamp device 47 move down to the positions at the time of each transfer in synchronism with the downward movement to the position at the time of transfer of the pallet 7, the pallet 39 is detached from the lower side of the formwork 28 and the connecting block 10 is demolded. At this time, the pressing die 54 also moves downward in synchronization with the downward movement of the lifting table 37 to the position at the time of transport, thereby facilitating detachment of the pallet 39 from the formwork 28 and the semi-cured connection block 10. Is suppressed. Therefore, the connecting block 10 shown in FIG. 1 is held in a semi-cured state on the detached pallet 39. By synchronizing the lowering movement of the lifting table 37, the supply device 42, and the clamp device 47 to the respective transport positions, the semi-cured connection block 10 is torn by the connection member 20 embedded as described above. And other damage.

Then, after the pallet 39 is completely removed from the mold frame 28 downward, the pressing die 54 is moved upward by a moving device (not shown) and waits at a predetermined position. Also,
As shown in FIG. 9, the clamp device 47 releases the gripping state of the connecting member 20, and further moves down to the retracted position. Then, after the movement of the clamp device 47, the pallet 39 on the elevating table 37 is moved onto the unloading device 41 by a pusher (not shown) so as to pass over the clamp device 47 at a position indicated by a two-dot chain line in FIG. Move up to. At this time, since the connecting member 20 partially embedded in the connecting block 10 is not separated from the connecting member 20 wound around the roll 45 of the supply device 42, the connecting member 20 moves with the movement of the pallet 39. The roll 45 rotates. Therefore, when the connecting block 10 moves to the position shown by the two-dot chain line shown in FIG.
Above, the connecting member 20 has already been arranged for manufacturing the next connecting block 10.

Then, as shown in FIG. 10, when the movement of the connecting block 10 is completed, the clamp device 47 retracted to the retract position moves up again to the position at the time of transportation, and the connecting member 20 is moved by the clamp member 52. After the holding, the cutter member 53 cuts the connecting member 20. Therefore, the connecting member 20 partially buried in the connecting block 10 and the connecting member 20 wound around the roll 45 are in a separated state. Then, the connecting block 10 is transported by the unloading device 41 to a storage position (not shown). Thereafter, the connection block 10 is completely dried and hardened, and is removed from the pallet 39, so that the usable connection block 10 can be completed. Further, if the pallet 39 removed from the formwork 28 is moved onto the unloading device 41 and a new pallet 39 is set on the elevating table 37, the next connection block 10 can be manufactured continuously.

As described in detail above, according to the present embodiment, the following effects can be obtained. (1) The connection block 10 can be continuously manufactured using one mold frame 28 by the pressure molding method, and the manufacturing efficiency of the connection block 10 can be significantly improved.

(2) When removing the pallet 39 from the mold frame 28, the pallet 39 is synchronized with the downward movement of the lifting table 37,
Since the supply device 42 and the clamp device 47 are moved downward, the connecting member 2
With 0, the possibility of damaging the semi-cured connecting block 10 can be eliminated.

(3) Since the material is supplied while applying vibration to the formwork 28, the raw material supplied into the formwork 28 can be made dense, and the high-quality connection block 10 which does not cause cavitation can be provided. Obtainable.

(4) Pallet 3 detached from formwork 28
9 is moved to a predetermined position by the unloading device 41 and then the connecting member 20 is cut, so that the supply device 42 continuously arranges the connecting member 20 on the elevating table 37 as the pallet 39 moves. You can do it. Therefore, the process can be simplified and the manufacturing efficiency can be improved.
