Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for molding patterned bricks in which an uneven pattern is continuously added to the surface of the bricks.

Bricks are widely used as building materials for walls, floors, fences, etc., but their surfaces are generally unpatterned, making them look plain and lacking in flavor.

Therefore, in order to add a predetermined pattern to the bricks,
Conventionally, patterns have been created by bringing uneven rollers into contact with the molded material during the molding stage, but it is not possible to create deep patterns with the contact action of the rollers alone, and if the contact pressure of the rollers is increased. This method has drawbacks such as the possibility that excessive force may act on the molded material, causing deformation of the molded material.

In view of these drawbacks, the present invention provides a press plate which is disposed above the advancing trajectory of the molded material discharged from an extrusion molding machine and has various uneven patterns formed on its lower surface, while the molded material discharged from the extrusion molding machine advances. Pressurized contact is made to the top surface of the molded material while moving it in synchronization with the speed,
It is an object of the present invention to solve the above-mentioned drawbacks by providing a method and apparatus for molding patterned bricks in which both sides of the molded material are guided by guide rollers while being pressurized by a pressing plate. One embodiment will be described based on the drawings. 1 is the main body of a patterned brick molding machine, frames 5, 5a are arranged on both sides of a conveyor 4 connected to a nozzle 3 of an extrusion molding machine 2, Guide shafts 7, 7a are provided above the conveyor 4 during the traveling trajectory of the molded material W via support legs 6, 6a...
are arranged parallel to the conveyor 4, and a base 8 is attached to the guide shafts 7, 7a so as to be slidable back and forth, and a feed cylinder operated by air or hydraulic pressure is installed between the ends of the guide shafts 7, 7a. 9 is attached, and a feeding mechanism 11 is provided, which connects the rod 10 of the feeding cylinder 9 to the rear end of the base 8, and by the action of the feeding mechanism 11, the base 8 is synchronized with the extrusion progress speed of the molded material W. It is designed to control the reciprocating movement.

It goes without saying that the feed mechanism 11 may be moved by a crank type or the like instead of the feed cylinder 9.

Further, a pressurizing cylinder 12 operated by air or hydraulic pressure is mounted vertically on the base 8, and a lifting mechanism 1 has a support plate 14 connected and supported by a rod 13 hanging downward from the pressurizing cylinder 12.
5, and the lower surface of the support plate 14 has horizontal wrinkles on the surface.
A press plate 17 on which various uneven patterns 16 such as vertical wrinkles and geometric patterns are formed is removably attached, and the press plate 17 is controlled up and down by the action of the pressurizing cylinder 12 to move the molded material W on the conveyor 4. A concavo-convex pattern 16 is applied under pressure to the upper surface of the plate.

The pressing plate 17 is made of natural weathered stone, plaster, plastic, gunmetal, cast iron, brass, or any other material suitable for pressing.

Further, the molded material W is placed on the frames 5, 5a corresponding to the pressure action range of the press plate 17 on the molded material W.
Guide roller 1 for contacting and guiding both sides of the
8, 18a... are arranged.

Further, between the main body 1 and the extrusion molding machine 2, a hopper 20 is disposed above the base end of the conveyor 4 via a support frame 19 erected on the frames 5, 5a. Powdered materials such as sand, shavings, wood chips, manganese, iron oxide, and other inorganic and organic materials are optionally loaded, and the molding material W is discharged through the discharge port 21 at the bottom of the hopper 20.
The opening position corresponds to the top surface of.

Next, the method for molding patterned bricks according to the present invention will be explained. In the process in which the molded material W is discharged from the nozzle 3 by the operation of the extrusion molding machine 2 and advances on the conveyor 4, it is pressed by the operation of the pressure cylinder 12. The conveyor 4 is moved by lowering the plate 17.
Pressure is applied to the upper surface of the molded material W, and in this state, the feed cylinder 9 is operated to maintain the pressurized state of the press plate 17 and perform a predetermined pitch follow-up operation in synchronization with the advancing speed of the molded material W. At least the uneven pattern 1 on the surface of the pressing plate 17 is formed on the molded base W.
6 is applied, and during this pressurizing action, the molded substrate W is guided and supported by guide rollers 18, 18a, etc. arranged at opposing positions on both sides, and then the pressurizing cylinder 12 is moved backward to move the press plate 17. At the same time, the feed cylinder 9
is moved backward to return the press plate 17 to its original position, and by repeating this operation, an uneven pattern 1 is formed on the molded material W being moved on the conveyor 4.
6 is applied continuously.

Note that the transfer pitch of the feed cylinder 9 is
By setting the length shorter than the length of the pressure plate 7, it is also possible to apply double or triple pressure from the pressure plate 17.

In another invention, the discharge port 2 of the hopper 20
1, sand, wood chips, wood chips, manganese, iron oxide, other inorganic substances, organic materials, etc. are spread and adhered as appropriate in advance, and then sand, wood chips, wood chips, manganese, iron oxide, etc. are spread together with the uneven pattern 16 by the subsequent pressurizing action of the pressing plate 17. , other inorganic substances, organic substances, etc. are embedded and adhered to the surface of the molding base W.

The molded base W to which the uneven pattern 16 etc. have been added in the manner described above is cut into predetermined dimensions, dried, and then fired to become patterned bricks.

In short, the present invention provides various uneven patterns 16 disposed above the traveling trajectory of the molded material W discharged from the extrusion molding machine 2 and on the lower surface thereof.
Since the press plate 17 on which is formed is brought into pressure contact with the upper surface of the molded material W while being moved in synchronization with the advancing speed of the molded material W, the pressurizing effect on the molded material W can be maintained for a long time. It is possible to ensure the attachment of the uneven pattern 16,
Further, the molded base material W is pressed by the pressing plate 17.
is guided on both sides by guide rollers 18, 18a, etc., so that it is possible to prevent the molded material W from being deformed in the lateral direction due to the pressing action of the pressing plate 17. Since the pressure action can be made strong, the uneven pattern 16 can be applied deeply and clearly to the molded material W.

In another invention, while the molded material W discharged from the extrusion molding machine 2 is moving, sand, shavings, wood chips, manganese, iron oxide, other inorganic substances, organic materials, etc. are scattered and adhered to the upper surface of the molded material W. Therefore, due to the pressurizing action of the press plate 17, these sands and the like adhere to the surface of the molded base W, and during the firing of the molded base W, these sands and the like dig in, fall off, or disappear due to firing. Together with the addition of the uneven pattern 16 by the pressing plate 17, it is possible to give the surface of the molded material W a pattern with a slightly different taste.

Therefore, the present invention has great practical effects, such as being able to continuously and automatically mechanically produce patterned bricks that have a natural flavor that looks handcrafted.
