Description

[Detailed Description of the Invention] This invention relates to a processing device for roughening the surface of concrete products, especially artificial stone.

The manufacturing method for artificial stone is to pour a pseudo-stone material mixed with materials such as white cement, fine stone, white citrus water, black citrus water, iron sulfate, yellow iron oxide, and red rosewood into a formwork, and then pour concrete into the pseudo-stone material. It is manufactured by pouring it on top of the .

In the artificial stone manufactured as described above, the surface of the artificial stone material is covered with cement paste, and it cannot give the impression of natural stone as it is.

For this reason, it is necessary to peel off the cement paste present on the surface of the pseudostone material and roughen the surface to give it the feel of natural stone.

Conventionally, in peeling off the cement paste as described above, an operator holds an air tool for peeling and strikes the surface of the pseudostone material with the tool to give it a rough surface finish.

However, manual work is not only inefficient, but also has the disadvantage that it is impossible to finish the entire surface with a uniform roughness.

This invention was developed to eliminate the above-mentioned drawbacks, and the purpose is to provide a surface processing device that can automatically and efficiently finish the surface of artificial stone into a uniform rough surface. be.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIG. 6, an example of the artificial stone 1 processed by the processing device of this invention is formed of two layers: a pseudo-stone material 2 and a concrete 3 underneath, and a chamfer 4 is formed around the surface of the pseudo-stone material 2. It may have been done.

The processing device of this invention can be adopted in two ways: a method in which the artificial stone is transported by a conveyor, and a cart method in which the processing device moves relative to the artificial stone.

First, a conveyor type processing device will be explained.

The processing device includes a belt conveyor 5 that conveys the artificial stone 1, a positioning mechanism 6 provided on the upper part of the conveyor 5 during the conveyance, and a position located ahead of the positioning mechanism 6 on the belt conveyor 5 in the conveyance direction of the conveyor 5. The conveyor 5 is constructed of a surface roughening machine 7 disposed at a position shown in FIG.

The positioning mechanism 6 includes, as shown in FIG. It is formed of a movable guide 11 that has elasticity for approaching the guide 9, and presses the artificial stone 1 passing between the guides 9 and 11 against the fixed guide 9, and performs positioning with the fixed guide 9 as a reference. It is.

As shown in FIG. 4, the surface roughening machine 7 includes a chisel 12 formed by bundling a large number of steel wires, and a drive machine that attaches the chisel 12 to its lower part and moves the chisel 12 up and down by supplying air. It is made up of 13.

The horizontal feed mechanism 8 is a frame 14 of the belt conveyor 5.
A rocking plate 1 whose rear end is supported by a pivot shaft 16 on a support stand 15 provided at
7, a support base 18 for attaching the roughening machine 7 to the tip of the swing plate 17, and a swing means 19 for swinging the swing plate 17.

The above-mentioned swinging means 19 shows an example in which a cylindrical cam is adopted, and a frame 1 is placed between the swinging table 17 and the bell I/conveyor 5.
4, a horizontal shaft 20 is rotatably supported, and although not shown, this horizontal shaft 20 is interlocked with a motor via a pulley or belt, and a cylindrical cam 21 is fixed to one end. .

An arm 22 parallel to the horizontal axis 20 is attached to the upper surface of the rocking table 17 so as to be movable in the longitudinal direction by being supported by a slide box 23 attached to the frame 14. A trochanter 24 is provided at the end of the arm 22. is the cam surface 2 of the cylindrical cam 21
1 a.

A link 25 is rotatably connected in the middle of the arm 22 with a pin 26, and the tip of the link 25 is inserted into a swing width adjustment groove 27 provided in the swing plate 17 via a bolt nut 28, so that the fixing position can be freely adjusted. are connected so that they can be

The movement stroke of the arm 22 given by the cylindrical cam 21 is always constant, but the link 25 that transmits the movement of the arm 22 to the swing plate 17 and the connecting position of the swing plate 17 are connected to a pivot 16 that serves as a swing fulcrum. The closer it gets to , the larger the amplitude can be.

Note that a return spring 29 is provided between the rocking table 17 and the frame 14, and the rocking plate 1 sent out by the cylindrical cam 21
7 is returned to its original state by the spring 29.

In the illustrated case, the surface roughening machine 7 is mounted on a support stand 18 so that its vertical height can be adjusted using a mounting bracket 30, as shown in FIG. The distance between the lower end surface of the chisel 12 and the surface of the artificial stone 1 placed on the conveyor 5 can be freely adjusted.

The surface roughening machine 7 is shown in which three units are installed side by side in the swinging direction, and the swinging plate 17 is moved by the cylindrical cam 21.
Oscillation is applied at an angle in which the amplitudes of adjacent chisels overlap.

An auxiliary frame 32 is attached around the artificial stone 1 to protect the chamfered portion during surface processing, and dust collection equipment may be used to improve the working environment.

The surface processing apparatus employing the belt conveyor system of this invention has the above-mentioned configuration, and the surface processing method will be explained next.

The artificial stone 1 which has been cured for a predetermined time and demolded is fed onto a belt conveyor 5 with the pseudo stone material 2 facing upward.

The artificial stone 1 is sent forward through the positioning mechanism 6, and at the same time as the conveyor 5 is running, the motor is activated to give rotation to the cylindrical cam 21, and the swing plate 17 swings back and forth through a predetermined angle. , air is supplied to the drive machine 13 of the surface roughening machine 7,
The chisel 12 moves up and down.

When the artificial stone 1 passes directly under the surface roughening machine 7, a chisel 12 that moves up and down strikes the surface of the pseudo-stone material 2.

The relationship between the artificial stone 1 and the chisel 12 is as shown in FIG. The chisel 12 roughens the surface of the pseudostone material 2 while moving in a zigzag pattern.

The above-described movement of the chisel 12 improves the peeling effect of the cement paste formed on the surface of the pseudostone material 2.

By passing directly under the roughening machine 7, the artificial stone 1
The entire surface of the pseudo-stone material 2 is processed to have a uniform rough surface, resulting in an artificial stone that is comparable to natural stone.

Next, Figures 7 and 8 show examples of the trolley system in which processing equipment moves.
This will be explained based on the diagram.

In this trolley system, the main parts of the above-mentioned conveyor transport system are attached to the trolley 41, and the equipment side is moved to the large artificial stone 1 that is difficult to transport by a conveyor. The same parts are given the same reference numerals and the explanation will be omitted.

The trolley 41 is formed in a hoof shape with respect to the artificial stone 1 FL
Screw shafts 42 are erected at the four corners of this truck 41, and a lifting platform 43 is installed between the front and rear fusion shafts 42 parallel to the moving direction of the truck 41 so that the vertical height can be adjusted. A surface roughening machine 7 and a transverse feed mechanism 8 are attached to the upper part of the machine, and a motor 44 of the transverse feed mechanism 8 is loaded on a lifting table 43.

The trolley system has the above-mentioned configuration, in which the trolley 41 is moved over the fixedly placed artificial stone 1, the motor 44 is started, pressurized fluid is supplied to the drive unit 13, and the chisel 12 is moved vertically and horizontally. The upper surface of the artificial stone 1 is processed into a uniformly rough surface by giving a reciprocating motion in the direction and moving the cart 41 at an appropriate speed in this state.

As described above, according to this invention, a plurality of drive units are installed side by side in the swing direction at the tip of a swing plate supported on a support base, and pressurized fluid can be supplied to each drive unit. A chisel that moves up and down is attached, an arm whose tip abuts a rotating cam placed on one side of the shaking plate is attached to the shaking plate, and the arm is constantly pressed against the rotating cam by a spring, and the chisel amplitude of the rotating cam and Since the spacing between the drive machines is set at an angle where the amplitudes of adjacent chisels overlap, when the rotary cam is rotated and pressurized fluid is supplied to the drive machines, the chisel performs a compound movement of vertical movement and rocking. , the top surface of the concrete product is struck, and since the amplitude of each chisel overlaps, there is no unbeaten area. Therefore, it is possible to automatically roughen the surface of concrete products and peel off cement paste from the surface of artificial stone. This greatly improves work efficiency.

In addition, since surface processing can be performed automatically, a uniform rough surface finish can be obtained over the entire surface, and it is effective in processing everything from the size that can be conveyed by a conveyor to large concrete products.
