Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention involves measuring concrete in advance according to the dimensions of the target product, moving it to the top of the formwork using a supply hopper with a shutter, and measuring the concrete into the formwork. ○ Related to a molding machine for composite concrete products that feeds and molds composite concrete products <Prior art> As a conventional technology of this invention,
Publication No. 7 is the closest one.

In this method, the four products shown in Fig. 13 are simultaneously laminated and molded using the formwork shown in Fig. 12 (plan view).

To explain this, the product M in Fig. 13 is a composite concrete product with an upper layer M' made of a different material, and each forming part l of the formwork 2 in Fig. 11 has a recess deeper than the total thickness of the product. It has become a department.

The required amount of material is dropped into each layer into the deep molding area, and the required size of the product is obtained by vibration and pressure.

Therefore, in the apparatus shown in FIG. 11, the formwork 2 is placed in the center, and material pressers 7.7 for the -F layer M' and the base layer M are placed on the left and right sides, respectively. Below each hopper 7, after filling the four measuring tubes 6a with materials in accordance with the arrangement of the molding section 1 in Fig. 12, the upper shutter 6c is closed and the lower shutter 6b is opened to drop the materials. A weighing device is attached, below which a conventional sliding hopper 10 also has four storage chambers 8.

111'' When the material falling from 6 enters each storage chamber of the sliding hopper 10, it moves onto the formwork 2, opens the shutter 9 and drops it into each molding section, and is vibrated by the vibrator 11. The press plate 4 is then flattened, inserted into each molding part 1, twisted, pressed, and pulled out.

Even if these steps are repeated and the base layer M and the upper layer M' are stacked, the top part of the mold forming part l is still empty, but the conveying pallet 3, which also serves as the bottom plate of the mold 1, is lowered and the As shown by the chain line in FIG. 11, the product is demolded downward, placed on a conveyor 41, and sent out.

<Problems to be Solved by the Invention> In the prior art as shown in FIG. It was unscrupulous, lacked sufficient precision to create thin layers of small products, and was troublesome to adjust.

In addition, when paving blocks with colorful surfaces are laminated and molded using conventional molding equipment, the irregularly shaped blocks E that form the edge of the road surface are many in variety and the number is extremely small. It takes more than an hour, and if the formwork is changed on the same day and different-shaped blocks are produced, the operating efficiency will be significantly reduced, so the various different-shaped blocks that will be installed at several different construction sites are molded all at once. There is.

For this reason, when the blocks were laid, the colorful colors covered in the inventory faded, and the color unevenness between the regular blocks and the irregular blocks became clear, and the image of the entire pavement surface was significantly impaired. Means for solving the problem> The laminated material feeding device for the molding machine of the present invention is provided with a weighing box 12 dedicated to each material, which has a hole 13 with a volume equal to the volume of each material to be laminated, and a shutter that closes the bottom surface of the hole 13. The above-mentioned measuring box for the bottom layer is connected to the above-mentioned sliding phone of the material concerned.
(- After applying the material directly below the sliding end and filling the hole with the material, move the weighing box directly above the formwork, open the shutter 9 and drop the material into the formwork to prevent vibrations. Then, in the same way, drop the upper layer materials one by one into the formwork and stack them, filling only the top layer material directly to the top of the formwork with a sliding hone. be.

In addition, in order to efficiently form many types of small-volume products such as irregularly shaped block E with the same rod, it is possible to separate the connection between the press plate 4 and press equipment #5 in order to simplify the exchange of press plates and molds. A mounting/detaching device 16 is provided for positioning the press plate with respect to the mold hole of the mold and assembling it on the mold, and a guiding device 25 for guiding the material to the mold and onto the molding area and a holding device for the mold are provided. This made it easier to replace the formwork and press plate.

<Function> A sliding hopper is placed from each parent hopper placed on the outside of the formwork and containing stacked dissimilar materials to -F of the weighing pan having a hole with a volume equal to the volume of the hopper. The material is weighed by moving it back and forth into each punched hole, and the material filled in this hole is moved while being held in the hole by a shutter, and when it reaches just above the formwork, the shutter is opened. The process of supplying the weighed material into the formwork, flattening it by vibration or press as necessary, and supplying the next material is repeated, and the top layer is directly filled to the top of the formwork with a sliding hopper for laminated molding. Yes 0 Also, when replacing the press plate and formwork, it is necessary to align the press plate accurately with the mold hole of the formwork, carry it from under the press machine to the opposite supply material and forming area, and then lower the press machine. ,
Raise the formwork to bring the press plate and press equipment close together,
The drive device is activated to connect the attachment/detachment devices provided on both sides, and the formwork is held in the material supply and molding area, thereby supplying material to the press plate and the molding machine, and connecting the mold hole of the formwork held in the molding area. The press plate and the mold can be installed in the molding machine at the same time by accurately aligning them in the vertical direction. shows.

Components with the same function as the conventional example in Fig. 11 are given the same reference numerals.In addition, the sliding hopper tOVi in Fig. 11 and the trailing horizontal plate that blocks the exit of the hopper 7 are the main parts (7 was not included, but this The sliding hopper 10 of the invention has the general shape shown in FIGS. 5 and 6.

The explanation of the operation of the embodiment shown in FIGS. 5 and 6 is based on the new metric p+
This is done first for the left side material (for M' in Fig. 1θ) using No. 12.

The operation begins by sliding the sliding hopper 10 from below the parent hopper 7 onto the weighing pan 12 directly below the sliding end, as shown in FIG. F indicates the sliding floor surface. The sliding hopper 10 immediately returns to its original position, and the weighing box 12, together with the attached shutter 9, slides on the sliding floor surface F' and reaches the top of the formwork 2, resulting in the state shown in FIG. Then, when the shutter 9 is opened, the material in the punch hole 13 of the weighing box 12 falls into the forming fffll of the formwork 2, as shown in FIG. Then, the vibrator 11 is activated to flatten the surface of the material, and if necessary, the press device 5 is also lowered to apply pressure.

Since this embodiment is intended for the product shown in FIG. 1O, after the lower layer material is filled into the formwork 2 through the above steps, the uppermost layer is immediately placed on top of it. For the uppermost layer, the molding section 1 of the formwork 2 only needs to be completely filled with material, so there is no need to use the weighing pan 12 to measure the material. Conventional sliding hopper 10
If the excess material than the required amount is advanced onto the formwork 2 and returned, the upper surface of the molding section 1 is filled with the material. The subsequent vibration, pressurization, and demolding processes are the same as before.

In the embodiment shown in FIGS. 5 and 6, the moving direction of the sliding hopper 10 that rides onto the weighing box 12 directly below the sliding end is the same as the moving direction of the weighing box 12 onto the formwork 2. The moving direction of can also be changed freely according to design conditions.

Next, a description will be given of an embodiment in which the formwork 2 and press plate 4 are replaced in order to mold the irregularly shaped blocks shown in FIG. 14 using the same batch of concrete.

To install the mold and press plate into the molding frame 19, the piston of the cylinder 32 is extended upward. As a result, the left and right rails 35 pass through the recess 37 and are lifted above the upper surface of the deck 22, so that they are at the same level as the left and right retaining portions 36 on the lower surface of the formwork carried on the conveying device 25.

Next, as described above, the left and right rods 48, 48 are advanced as far as possible, and the claws 49, 49 at their tips hook the left and right sides of the rear end plate of the formwork, and the rods are moved backward.

Due to this/''L, the formwork and the press die assembled thereon move backward together, and the engaging portion 36 slides into the left and right rails 35 from the rear end and transfers from the top of the conveying device to the left and right rails. In this way, when the formwork and the press die reach directly above the fitting part 38, this is detected by, for example, a limit switch, and the left and right rods 48 are temporarily stopped in the backward direction, and each of the left and right claw pieces 4
Push the rear end of 9 with a button 39 such as a piston cylinder/cylinder to open the pawl @2s''III (Fig. 2), and move the rod 48 backward to the most retracted position.

Next, once the formwork is connected to the fitting part 38 with the piston of the cylinder 32.
After lowering the press 37 on the bottom of the formwork into the upper end of the vibration table 17 and bringing the formwork and the press mold assembled on it into the correct position within the fitting part, the formwork and press mold are It is raised to the original loading position using the piston of the cylinder 32.

Then, the piston of the press device 5 is extended downward, and the later-described attachment/detachment device 16 on both the press device and the press mold is coupled with the drive device to attach the press mold to the press device, and the piston is pulled up to move the press mold into the formwork. The formwork is lowered into the fitting part 38 by the piston of the cylinder 32.

To transport the formwork and press mold onto the transport device 25 in order to exchange them, raise the piston of the cylinder 32, lift the formwork with the left and right rails 35 to a loading position above the deck, and then lower the press device. After assembling the press mold on the mold frame and releasing the attachment/detachment device 16 by the drive device 17, the left and right rods 48 are moved forward from the retreated position to the maximum. As a result, the front end of each rod 48 or the tip of the claw pieces 49, 49 pushes the rear end plate of the formwork, causing the engaging portion 36 of the formwork to escape from the left and right rails and transfer onto the conveying device 25. . To install the next formwork inside the molding frame, the left and right rods are moved backward a little and stopped, the guides 28 are advanced, the claws of the claw pieces 49 are opened, and the next formwork is placed on the conveying device. When it is brought in, move the left and right rods forward as far as possible, hook the left and right sides of the rear end plate of the formwork with your claws, and move the left and right rods backward. The rest is as described above.

To mold the product, use the piston of the cylinder 32 to move the recess 37 on the bottom of the mold a little upward from the top of the vibration table 31 in the lowered state, and place the previously molded product on the photographing table using the pallet feeder 40. The old bottom plate is pushed out onto the conveyor 41, and a new bottom plate is supplied onto the vibrating table.

To replace the press plate 4, when the press device 5 is lowered, the protruding piece 15 enters the hole 45 and protrudes onto the mounting plate, and the left and right threaded portions of the turnbuckle 46 enter the upwardly opening openings 44 of the protruding piece. The lower surface of the mounting plate 4' is the upper surface r of the board 14.
come into contact with

Therefore, the turnbuckle 46 is rotated in one direction by the drive device [17, the wedges 47 are moved on the mounting plate in a direction toward each other, and the wedges 47 are entered into the grooves of the left and right protruding pieces, respectively, and the wedges 47 are moved toward each other on the mounting plate. The H surface and the upper surface of the opening 44 of the protruding piece are wedged together to perform the connection.

To remove the coupling, the drive device 17 rotates the turnbuckle 46 in the opposite direction to remove the wedge 47 from the protruding piece. In this way, at the same time as replacing the formwork and press plate, the weighing box is also replaced with one having punched holes equal to the volume to be laminated.

After completing such preparatory work, in order to layer-mold a new product, the sliding hopper 10 is slid from below the parent hopper 7 onto the replaced weighing pan 12 directly below the sliding end, and the input amount is measured. .

In the following, each molding process is performed by moving the material to the molding section according to the molding procedure described above.

An example of molding products of different shapes from the same batch of concrete IJ-contact in the parent hopper has been described above, but in carrying out the present invention, without changing the gist of the invention, the design It is natural that various changes and applications will be made depending on the well-known technology of the person, especially the hole 13 of the weighing well 12.
The dimensions, shape, and arrangement are sufficient as long as they allow the required amount of material to fall into the forming part 1 of the formwork under its own weight. It may be changed as appropriate, such as increasing the size.

Note that the different materials to be composited may be of any material as long as they are compatible with Masuke Shun.

<Effects of the Invention> The forming machine of the present invention allows the press plate and formwork to be replaced in just a few minutes even when concrete is stored in the parent hopper, so it is possible to change the thickness by using concrete of the same punch without hardening the concrete. It is possible to mold products with different colors and shapes, and all the products needed during construction can have a uniform colored surface with no uneven color.

Also, since a special measuring box is used, the thickness of the laminated materials can be changed freely, so expensive composite materials can be easily changed as needed depending on the construction site.

In this way, this molding machine allows production according to made-to-order production.
Moreover, manufacturing costs have been significantly reduced.
