Description

[Detailed Description of the Invention] The present invention enables the regulation of the amount of movement of stone to be processed to be changed accurately and quickly with a single touch operation in a stone polishing machine, a stone cutting machine, or the like.

In the conventional system, as shown in Fig. 1, a stone 1 on a traveling carriage is sandwiched between the projectors 3a and 2' placed on brackets 2 and 2', which are installed in a vertical position parallel to the traveling carriage.
While looking at the scale 5 on the brackets 2, 2', fix the sliders 4a, 4'a to which 3'a is attached, and the sliders 4b, 4'b to which receivers 3b, 3'b are attached, respectively. This was done by making adjustments, and the adjustment was troublesome and required a considerable amount of time.

The present invention aims to eliminate such drawbacks, and an example of the implementation of the present invention will be described below with reference to FIG. 2 and the subsequent drawings.

Reference numerals 10a, 10b and 10'a, 10'b are two pairs of regulating rods that face each other with the stones on the traveling truck in between, and their lower ends are rotated by bearings 11 so as to form a V-shape at one side position. Freely supported swing shaft 1
2, 12'. However, at the tip of one side of each regulating rod, there are projectors 13a, 13'a.
On the other hand, the opposite tip has a light receiver 13b, 1
3'b are provided so as to correspond to each other in each pair.

Reference numeral 14 denotes a support rod provided on the bearing 11 at a central internal position of the restriction rods 10a, 10'a, and is provided at a constant height position.
It is supported by a horizontal shaft 15 for moving 0'a and 10'b toward and away from each other at the same time. 1
Reference numeral 6 designates the bearing, a disc 17 is integrally attached to the shaft 15, and a cylindrical pipe 18 is provided in front of the disc 17.
is loosely fitted. Therefore, the disk 1 of the tube
A rotating plate 19 of the same size is integrally attached to the edge opposite to the lever 7, and a lever 20 is screwed into a threaded hole 21 at the other end. By screwing in, the horizontal shaft 15 can be fixed at a fixed position by pressing the horizontal shaft 15 with its tip.

On the other hand, cranks 23, 22' of equal length are rotatably attached to the rotating plate 19 via pins 22, 22' at symmetrical positions equidistant from the axis of the rotating plate 19. The other ends of the cranks 23, 23' are connected to the regulating rods 10.
a, 10'a are rotatably supported by bearings 24, 24' at fixed height positions.

The present invention is constructed as described above, and the lever 2
When the rotary plate 19 is rotated clockwise or counterclockwise by operating 0, that is, when it is rotated in the direction of arrow P in the state A as shown in FIG.
The regulating rods 10a and 10b are cranks 23, 23'
When it is pulled inward by the arrow P', the distance 1 is reduced and becomes as shown in B. On the other hand, when it is rotated in the direction of arrow P', it is pushed outward and the distance 1 is expanded and becomes as shown in C. This allows the control rods 10a, 10b and 10'
a and 10'b approach and move away from each other at the same time.

In this invention, each pair of regulating rods is equipped with a light projector and a light receiver, and light is constantly projected, and the direction of the traveling truck can be changed by blocking or receiving the light. It will be done. Therefore, when used as shown in Fig. 5B, with the distance 1 between them, the edge A of the stone 1 will be at a position where it passes through A' when the traveling carriage moves to the left or right. At this point, the running direction of the carriage can be immediately changed at the position where edge R passes through R'.
In the drawing, reference numeral 25 denotes a polishing whetstone, which polishes the surface of the stone 1 while rotating.When fixing the regulating rods by narrowing the interval l as described above, the polishing whetstone 25 is used when changing the direction of the cart. The edge of the stone material 1 comes to protrude from the edge of the stone material 1. On the other hand, when the interval l is expanded as shown in state C, the direction change positions of the cart are A'' and B'', and the polishing wheel 2 is
The polishing work is performed without the edge of stone 5 protruding from the edge of stone 1.

Considering the case of polishing the entire surface of the stone 1 to a uniform horizontal surface, one of the important points is how to change the direction of the cart during the polishing process and determine the amount of movement of the stone. According to Lever 2
By appropriately rotating the 0, it is possible to regulate the amount of stone movement as described above with a single touch operation, which is very convenient as it can be done quickly and accurately.

In carrying out the present invention, appropriate scales 26 and 26' are provided on the upper periphery of the disc 17 and the rotating plate 19, and when the lever 20 is rotated, the distance between the regulating rods for a certain rotation angle is determined. It is convenient to make it readable. In the illustrated example, the bearings of the swing shafts of the regulating rods are placed on the floorboard, and each regulating rod expands and contracts upward, but this is not the case for stone processing machines. It may be attached to the head side beam to which the polishing disk or cutting blade is attached, and may be provided in a downwardly hanging state, and this is within the scope of the implementation of the present invention. Furthermore, the operating means using the lever 20 described above may also be provided on the side of the regulating rods 10b, 10'b.
