Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for molding patterned bricks, which is capable of continuously adding different patterns to the facing surface of the bricks.

Such bricks are widely used as building materials for walls, floors, fences, etc., but they generally have no pattern on the surface, so they look plain.

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 this, the present invention aims to eliminate the above-mentioned drawbacks by providing a device that adds an almost infinite number of different patterns to the exposed surface of a brick using a plurality of pairs of rollers that do not have common divisors. Hereinafter, an example of the embodiment of the present invention will be explained based on the drawings.The patterned brick molding apparatus according to the present invention is a molded material that is continuously extruded from a nozzle 2 of an extrusion molding machine 1 along a roller conveyor 3. Frames 5, 5/ are provided at predetermined spacing positions facing both sides of frame 4, and a pair of abbreviated upper and lower arm rods 6, 6' are installed inside the frames 5, 5'.
. . . are arranged at predetermined intervals and pivotally supported at one end of each arm rod 6, 6' .
7'... and fix the support pieces 7, 7l.
. . . Transfer rollers 9, 9', between which various uneven patterns 8, 8', such as horizontal registration, vertical registration, and geometric patterns, are formed on the surface.・Molded base 4 with marking surfaces 10 on both sides.

A plurality of pairs are rotatably supported so as to face each other.

Furthermore, at least the transfer rollers 9, 9' provided on the same side...
... are set to different diameters that have no common divisors.

Further, support shafts 1 1 , 1 1 ′ ... are respectively pivotally attached to the distal ends of the arm rods 6, 6', . 1 Fix one end of the screw punch 12, 12'....... approximately in the center of 1'... and screw in the nuts 13, 13'.... 1 3, 1 3'... and frames 5, 5
/ A compression coil spring 14 for tension between.

Press in 14'... and screw punches 12, 12'...
...Insert the other end into the frame 5, 5' and hook it with nuts l5, 15'...
,13'...

Transfer roller 9 by adjusting 15.15'...
, 91 . . . to the molded base 4 and the elastic force of the compression coil springs 14 , 14' . . . can be adjusted.

Further, a hopper 16 is provided above the transfer rollers 9, 9', and its lower discharge ports 17, 17' are opened toward both sides of the molded material 4, so that sand, sand, etc.
Chamotte, wood chips, and other organic substances are supplied and deposited onto the facing surface 10, 10' of the molding base 4.

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

Next, to explain the operation of the patterned brick molding apparatus according to the present invention, the molded base 4 extruded by the extrusion molding machine 1
While moving forward on the roller conveyor 3, when it first reaches the position of the first stage transfer rollers 9, 9, the transfer rollers 9,
9 is adjusted so as to come into contact with the facing surface 10.10' of the molding base 4, so that it contacts and rotates as the molding base 4 moves forward.
Along with this, a predetermined uneven pattern 8° 8' . . . is added to the surface of the transfer rollers 9, 9.

Subsequently, the molded base material 4 is sequentially similarly shaped into a predetermined uneven pattern 8, by the second and third stage transfer rollers 9/, 9//.
8'... are added in an overlapping manner, but since each transfer roller 9, 9'... is set to a different diameter that does not have a common divisor, each transfer roller 9, 9'... 9'・
The patterns that are covered and added by ... do not appear repeatedly at a fixed period, but become nearly infinitely different patterns.

Also, uneven patterns 8, 8' are created by transfer rollers 9, 9/...
In the process of adding sand to the hopper 16,
Discharge chamotte, wood chips, and other organic matter through outlet 17°17'
By discharging the sand onto both sides of the molded material 4, the sand and the like adhere to the molded material 4, and immediately after that, the transfer roller 9
//, 9// uneven pattern 8, 8'...
As the material is added, it is crimped and an even more interesting pattern is added.

In addition to the above-mentioned natural fall, the supply of sand, etc. can be forcibly blown with air, blowers, pumps, rotary centrifuges, etc., depending on the strength, amount, and vertical, horizontal, and diagonal directions. If you do this, you will be able to achieve even greater effects of change.

The molded base material 4 to which the pattern has been added in this manner is cut into a predetermined size, dried, and then fired to form the patterned brick A.

In short, the present invention provides various uneven patterns 8, 8' on both sides of the molded material 4 discharged from the extrusion molding machine 1.
A plurality of pairs of transfer rollers 9, 9'...
Since the transfer rollers 9, 9', . 9, 9'... Surface unevenness pattern 8, 8'.
. . . can be applied continuously, and at least the transfer rollers 9, 9' . . . are provided on the same side.
・ are set to different diameters that do not have a common divisor, so each transfer roller 9゜9 that is added to the molding base 4
'..., uneven patterns 8, 8'... are added at different intervals, so the combined uneven patterns 8
, 8'... can be made to be nearly infinitely different.

Further, a hopper 16 to which sand, chamotte, wood chips, and other organic materials are supplied is provided at a position above and in front of the arbitrary transfer rollers 9//, 9//, and a discharge port 17.1 of the hopper 16 is provided.
By opening 7' on both sides of the molding base 4, sand, etc. can be attached to both sides of the molding base 4 and immediately pressed by the transfer rollers 9//, 9//, and such sand, etc. can be removed. During the firing of the molded base 4, sand or other particles of different sizes may be dug into or fallen off, and differences in size may occur on the surface, resulting in slight differences in the uneven pattern caused by the transfer roller 9. It is possible to produce bricks with a good taste.

Therefore, the present invention has great practical effects, such as being able to mechanically and continuously produce patterned bricks A with different patterns that look handmade.
