Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding patterned bricks, in which various inorganic and organic substances are adhered to the textured surface of the bricks along with uneven patterns, thereby continuously adding different patterns.

Conventionally, such bricks have been widely used as building materials for walls, floors, fences, etc., but generally the bricks have no pattern and therefore have a plain appearance.

Therefore, it is possible to add a pattern using a press mold with a predetermined pattern engraved on it, but since the pattern applied to each brick is the same, it lacks flavor. could not be manufactured.

In view of such drawbacks, the present invention provides a plurality of transfer rollers having various uneven patterns formed on the surface thereof, which are rotated in contact with each other on both sides of a molded material discharged from an extrusion molding machine, and at least those on the same side are rotated in contact with each other. Different diameters with no common divisors are set, and each transfer roller is used to continuously add uneven patterns to both sides of the molded material, such as obsidian, Shinju rock, glass, sand, chamotte, other inorganic materials, and wood chips. An attempt has been made to solve the above-mentioned drawbacks by providing a method for molding patterned bricks in which other organic substances, etc. are attached to both sides of the molded material before any transfer roller, and hereinafter, one embodiment of the present invention will be described. To explain an example based on the drawings, 1 is an extrusion molding machine, and a predetermined space is formed on both sides of a molded body 4 which is continuously extruded from a nozzle 2 of the extrusion molding machine 1 along a roller conveyor 3. frame 5 in position
．． A pair of upper and lower arm rods 6.6a, .・A support piece 7.7a... is fixed to the other end, and the support piece 7.
．． 7a... transfer rollers 9.9a... with various uneven patterns 8.8a... such as horizontal wrinkles, vertical wrinkles, geometric patterns, etc. formed on the surface between them are placed on the facing surfaces on both sides of the molding base 4. 10.1
A plurality of pairs are rotatably supported so as to face each other.

Note that at least the transfer rollers 9.9a and 9.9a provided on the same side
... are set to different diameters that have no common divisor.

Further, support shafts 11, lla, etc. are respectively pivotally attached to the distal ends of the arm rods 6.6a, extending between the upper and lower sides, and the support shafts 11.1.
1a... At the same time, fix one end of the screw punch 12.12a... to the approximate center of the screwdriver 1a... and screw in the nut 13.13a...
A compression coil spring 14.14a for tension is installed between the nut 13.13a... and the frame 5.58.
Press-fit the other end of the screw punch 12.12a into the frame 5.
．． 5a and latched with nuts 15.15a..., nuts 13.13a..., 15.15
The contact position of the transfer roller 9.9a with respect to the molded substrate 4 and the compression coil spring 1 are adjusted by adjusting the a...
4.14a...'s rebound force is adjustable.

Further, a hopper 16 is provided at an upper position in front of any transfer roller 9.9a, and a discharge port 17.17a is provided below the hopper 16.
Open the hopper 1 toward both sides of the molding base 4.
Obsidian, Shinju rock, glass, sand, chamotte and other inorganic substances, wood chips and other organic substances are supplied into the molding body 6 and are discharged and adhered to the facing surface 10.10a of the molding base 4.

Note that 18 is a chute for collecting falling obsidian and the like.

Next, the method for molding the patterned brick A according to the present invention will be explained. First, a plurality of pairs of transfer rollers 9.9a are provided to face the facing surfaces 10.10a on both sides of the molded material 4 discharged from the extrusion molding machine 1. Arm rod supporting 6.6a...
・ is rotated inwardly, and each transfer roller 9.9a...
Nuts 13.13a..., 15.15a... are brought into contact with a slight elastic force due to the action of a...
Adjust accordingly.

After that, when the extrusion molding machine 1 discharges the molded material 4, the molded material 4 first reaches the position of the first stage transfer roller 9 while moving forward on the roller conveyor 3, and the transfer roller 9 transfers the material to the molded material. Since it is adjusted so as to come into contact with the facing surface 10.10a of the transfer roller 9, it contacts and rotates as the molded base 4 moves forward, and accordingly, a predetermined uneven pattern 8.8a... is added to the surface of the transfer roller 9. It is.

Subsequently, the molded base material 4 is sequentially similarly shaped into a predetermined uneven pattern 8.8a by the second and third stage transfer rollers 98.9b.
... are added in layers, but each transfer roller 9.9a.
... are set to different diameters that do not have common divisors, so the pattern added in a complex manner by each transfer roller 9.9a ... does not appear repeatedly at a constant period, but becomes an almost infinitely different pattern. be.

Also, the uneven pattern 8.8a is created by the transfer roller 9.9a...
In the process of adding..., obsidian, sinju rock, glass, sand, chamotte and other inorganic substances, wood chips and other organic substances are discharged from the discharge ports 17.17a onto both sides of the molding base 4 by the omper 16. Obsidian and the like adhere to the molded base 4, and immediately after that, are pressed together with the addition of uneven patterns 8, 8a, . . . by transfer rollers 9b, 9c, thereby adding a more tasteful pattern.

In addition to the above-mentioned natural fall, the supply of sand, etc., can be forcibly blown with air, or blowers, pumps, rotary centrifuges, etc. can be used to adjust the strength, amount, and vertical, horizontal, and diagonal directions. The molded base 4 with the pattern added in this way is cut to a predetermined size, dried and fired, and during the firing process obsidian, Shinju rock, etc. Inorganic materials such as glass, sand, and chamotte can be exploded, melted, or remain as they are, and organic materials such as wood chips can be burned to form voids, creating natural patterns. It is.

In short, the present invention rotates in contact with a plurality of transfer rollers 9.9a on which various uneven patterns 8.8a... are formed on both sides of a molded base 4 discharged from an extrusion molding machine l, and At least those on the same side of the rollers 9.9a... are set to different diameters that do not have a common divisor, and each transfer roller 9.9a... creates an uneven pattern 8.8a... on both sides of the molded material 40. . . . are layered and added continuously, so that the uneven pattern 8.8a . . . of each transfer roller 9.9a .
. are added at different cycles due to the different diameters of the transfer rollers 9.9a..., so the overlapping uneven patterns 8.8a... are the same as the respective uneven patterns 8.8a...
The transfer rollers 9.9a...- can have different diameters that are slightly out of phase with each other, and since the diameters of the transfer rollers 9.9a...
The repetition period of . . . becomes very long, and the added uneven patterns 8.8a . . . can be made to be nearly infinitely different.

In addition, since obsidian, Shinju rock, glass, sand, chamotte and other inorganic substances, wood chips and other organic substances were adhered to both sides of the molding base 40 before any transfer roller 9, 9a..., immediately after that, the transfer roller 9 .9a...
During the firing of the molding base 4, inorganic materials such as obsidian, sandstone, glass, sand, and chamotte may explode, melt, or remain as they are; When the organic matter burns, voids are formed in the area, and different sizes and shapes are formed on the surface, which together with the uneven pattern created by the transfer roller 9.9a... produces bricks with slightly different tastes. It is possible to do so.

Therefore, according to the present invention, it is possible to continuously mechanically produce patterned bricks with different patterns that look like handmade bricks, which have great practical effects.
