Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tile cutting device for cutting a fired tile.

[0002]

2. Description of the Related Art There is known a tile cutting device which cuts a fired ceramic tile by rotating a disk cutter (for example, JP-A-11-19922).

[0003]

A so-called split-skin tile having a natural uneven surface is currently being produced. However, such a split-skin tile has irregular surface irregularities and a large thickness. Due to the large variation in the height, there is a special characteristic that it is difficult to arrange a large number of sheets in a line and stably fix them all. Needless to say, if the fixing of the tiles is insufficient, accurate cutting cannot be expected, and it has been difficult to cut the split-skin tiles accurately with a tile cutting device.

Further, a diamond cutter is used in a conventional tile cutting device, and the cutting direction of the diamond cutter is specified. Therefore, when the diamond cutter is reciprocated linearly to cut the tile, the work is performed only in the forward process and the return process is merely a movement. Naturally, the moving time of the return process is a large time loss.

[0005] However, when the inventor dared to perform a cutting test of the tile with the diamond cutter in the opposite direction to the designated direction, it was found that the tile could be cut and that it was sufficiently used for a long time. The unexpected result was that it could be tolerated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and a first object of the present invention is to provide a tile cutting device capable of cutting a split-skin tile accurately. Another object of the present invention is to provide a tile cutting device that can be cut efficiently using a diamond cutter.

Cutting unit, a rail member for movably supporting the cutting unit, and a drive unit for moving the cutting unit on the rail member, one end is aligned with the work support table with this plate and Set a plurality of tiles in a face-up state, press and fix the clamp piece on the upper surface of the tile through the plate, and move the disk cutter in the fixed state. Providing a tile cutting apparatus adapted to cut the tiles ahead by.

In this tile cutting device, the flat back surface of the tile is placed on a work support, and the clamp pieces have a high degree of freedom with respect to the uneven surface, that is, each clamp piece independently and flexibly responds to the uneven surface. Since the surface of the tile is pressed and fixed by means of a comb or a clamp having a keyboard structure, the tile having an uneven surface can be reliably fixed. Therefore, the tile of the split skin can be cut accurately. In addition,
If the rotating surface of the disc cutter can be inclined at an arbitrary angle by pivotally attaching the cutting unit to the drive unit as in claim 3, the cut surface of the tile of the split skin can be inclined at an arbitrary angle. can do.

In addition, if the distance from the contact plate to the tip of the clamp piece is made variable, it is possible to flexibly cope with both long and short tiles.

Further, in order to achieve the second object, the present invention provides a disk cutter which is a diamond cutter and a cutter driving means is a motor capable of rotating forward and reverse so that the diamond cutter can be rotated forward and reverse. Provided is a tile cutting device in which a unit is reciprocated along a rail member, and a rotating direction of a diamond cutter is reversed between a going process and a returning process.

In this tile cutting device, the tile can be cut both in the forward path and the return path of the cutting unit by rotating the diamond cutter in the normal and reverse directions, so that the tile can be cut efficiently using the diamond cutter. It is.

Accordingly, the clamping means of the tile T has a comb structure in which a large number of clamp pieces 8 are arranged side by side in a row (however, when the interval between the clamp pieces 8 is small, a keyboard structure similar to a keyboard of a piano or the like is obtained. .). One cylinder 9 is provided for each set of the clamp pieces 8, and the clamp pieces 8 swing about the pins 11 by the vertical movement of the rod 10 of the cylinder 9.

A wooden plate 13 is laid on the upper surface of the clamp table 4 to protect the cutting edge of a disk cutter 12 described later. As shown in FIG. 5, the contact plate 7 is attached to the clamp table 4 with a tightening screw 70 provided at the end, and the position on the crank table 4 is changed by loosening the tightening screw 70. 4 can be changed along the long hole 4h. That is, the distance from the contact plate 7 to the tip of the clamp piece 8 is variable. Of course, the contact plate 7 may be fixed and the clamp piece 8 may be made movable so that the distance from the contact plate 7 to the tip of the clamp piece 8 can be changed.

In FIGS. 1 and 2, reference numeral 14 denotes a portal frame that stands upright so as to surround the work support table 1. The portal frame 14 has two vertical frames 15,
15, a horizontal frame 16 is placed over the top, and a rail member 17 in the form of a prism is attached in parallel with the horizontal frame 16.

The rail member 17 includes a vertical frame 15,
15 are slidably mounted on elevating rails 18, 18 fixed to the front of the front frame 15, and screw upwardly projecting screw shafts 19, 19 at both ends onto screw receiving members 20, 20 integral with the horizontal frame 16. It is suspended and supported by matching. Then, a female screw cylinder (not shown) provided inside the screw receiving members 20 and 20 is rotated forward and reverse by a motor 21 on the horizontal frame 16 to vertically move a screw shaft 19 screwed to the female screw cylinder. Thus, the height of the rail member 17 can be adjusted.

The rail member 17 has a disk cutter 12 as a diamond cutter and cutter driving means 22.
Is mounted via a drive unit 24 for reciprocating the cutting unit 23 on the rail member 17.

The cutter driving means 22 includes a motor 25 capable of rotating forward and reverse, a cutter shaft 27 parallel to a motor shaft 26 of the motor 25, a motor shaft 26 and a cutter shaft 2.
An annular belt 28 spans the shaft end of the cutter shaft 7, and the disk cutter 12 is attached to the tip of the cutter shaft 27 in a replaceable state.

On the other hand, the drive unit 24 is composed of a front plate 29 and a rear plate 30 which are positioned at the front and rear sides of the rail member 17, and side plates 31 which are integrally provided on the left and right between lower ends of the front and rear plates 29 and 30. , 31, guide rollers 32, 32, which are supported by the front and rear plates 29, 30 and roll in contact with the peripheral surface of the rail member 17, and a reciprocating drive motor 33 installed in front of the front plate 29,
A pinion gear 36 meshes with a rack gear 35 fixed to the output shaft of the reciprocating drive motor 33 and fixed to the front surface of the rail member 17.

The cutting unit 23 includes a driving unit 24
Are completely fitted between the side plates 31, 31, and both are axially mounted on a shaft 37. The side plates 31, 31 and the cutting unit 23 are connected by an adjusting screw 38 with a handle. The rotation of the adjusting screw 38 causes the cutting unit 23 to change its inclination about the axis 37. The side plate 31 has a locking member 3 of a clamp type.
9, a part of the cutting unit 23 is clamped by the lock member 39, and the cutting unit 2
The position of the cutting unit 23 is locked by connecting the side plate 3 and the side plates 31 and 31 integrally.

In addition, reference numeral 40 in the figure denotes the cutting unit 23.
A water injection hose 41 is connected to the cover member 40, and the cover member 40
And water is poured into the rotating disk cutter 12.

Next, a method of using the tile cutting device will be described. First, each part is set. The first setting operation is to adjust the angle of the rotating surface of the disk cutter 12. The angle of the disk cutter 12 can be changed by loosening the lock members 39 on both sides of the drive unit 24 to release the lock of the cutting unit 23, and then turning the adjusting screw 38 to tilt the cutting unit 23. In this way, for example, the angle between the rotating surface on the back side of the disk cutter 12 and the vertical line is set to 45 °. Tighten the lock members 39, 39 in that state,
The cutting unit 23 is firmly locked with the bowing posture.

The second setting operation is to adjust the height of the disk cutter 12. The height adjustment of the disk cutter 12 is performed by changing the height of the rail member 17 by rotating the motor 21 of the portal frame 14 in either the forward or reverse direction. Is set so as to pass through a position slightly above the surface of the plate 13.

The third setting operation is to adjust the front and rear positions of the clamp table 4. The front-rear position adjustment of the clamp table 4 is performed by rotating the adjustment screw 6 in either the forward or reverse direction, and the disk is located at a position away from the end of the plate 7 of the clamp table 4 by a required tile size. The setting is made so that the blade edge of the cutter 12 faces.

After the above-mentioned setting operation is completed, the tiles T are arranged in a horizontal line with the ends of the tiles T aligned with the contact plate 7 of the clamp table 4 as shown by the two-dot chain line in FIG. At this time, the direction of the tile T is facing upward. Next, the rod 10 of the cylinder 9 is extended as shown by a two-dot chain line in FIG. 4 to lower the tip of the clamp piece 8, and the tile T is pressed against the plate 13 of the clamp table 4 through the contact plate 7 at the tip of the clamp piece 8. At this time, since the clamp piece 8 is bent by the leaf spring structure, the tile T can be pressed with an appropriate pressure. Also, the clamping means is formed by arranging a large number of clamp pieces 8, 8... In a horizontal line to form a comb tooth or a keyboard structure. Therefore, even if the surface of the tile T is uneven or has a variation in thickness, each clamp piece 8 is formed. , 8... Securely fix the tiles T according to the unevenness and the thickness. It is preferable to press one tile T with one or two clamp pieces 8, although it depends on the interval between the clamp pieces 8, 8,... And the width of the tile T.

The clamp means of the embodiment in which the clamp pieces 8 are arranged to form a comb-tooth structure is replaced with a clamp means of a single-plate structure which covers all of a plurality of tiles T to be fixed with one sheet. For example, when the thickness of the tiles T, T... Is uneven, the clamp piece hits the thick tile T and stops lowering, so that the fixing of the thin tile T becomes insufficient.

It should be noted that the tile T may be fired while being pressed, or may be fired after being formed into a block shape and then divided into two pieces in order to create a natural texture (see FIG. 6). The former has a flat surface and little variation in wall thickness, while the latter has an uneven surface and different wall thickness.

Next, the motor 25 of the cutting unit 23 is driven to rotate the disk cutter 12 in the forward direction (clockwise in FIG. 1), and at the same time, water is poured into the cover member 40.
At the same time, the cutting unit 23 is moved from the position indicated by the solid line in FIG. 1 to the position indicated by the two-dot chain line in FIG. 1 by the rotation of the reciprocating drive motor 33 of the drive unit 24. In this forward process, the disk cutter 12
Cuts the tile T on the work support 1. The cut edge of the cut tile T is as shown in FIG.
It becomes oblique due to the inclination of the rotating surface of No. 2.

Next, when the cutting unit 23 reaches the position shown by the two-dot chain line in FIG.
Is retracted and the tip of the clamp piece 8 is lifted.
In this state, the cut tile T and the cut tile piece T
x is collected from the clamp table 4 and the next tile T is set as described above. Then, the motor 25 of the cutting unit 23 is rotated in the opposite direction to rotate the disc cutter 12 in the reverse direction, water is poured into the cover member 40, and the reciprocating drive motor 33 is further rotated in the reverse direction to move the cutting unit 23 as indicated by the solid line in FIG. Return to start position. In this return process, the disk cutter 12 cuts the tile T of the work support 1. In addition,
Although the rotation of the disk cutter 12 in the return process is not in the normal cutting direction, the tile T can be cut without any trouble.

Next, the cut remaining tile piece Tx is set again on the clamp table 4, the tip is cut off obliquely in the manner described above, and the cut piece of the long tile T cut first is cut as shown in FIG. Glue. At this time, since the tile piece Tx is considerably shorter than the previously cut tile T, the plate 7 is slid to the front end side of the clamp piece 8 and fixed.
The distance between the clamp table 8 and the clamp table 4
Set to.

In the embodiment of the present invention, the work supporting table 1 is fixed, and the cutting unit 23 is suspended from the rail member 17 to be moved. Since the tiles T are arranged at a higher place than the water sprinkling point, even if the tiles T are cut while discharging water, a unique effect that no trouble occurs in the electric system is exhibited.

[0033]

According to the cutting device for tiles of the present invention, the flat back surface of the tile is placed on the work support, and the clamp pieces have high flexibility with respect to the uneven surface, that is, each clamp piece is independently formed in accordance with the uneven surface. Since the surface of the tile is pressed and fixed by means of flexible comb teeth or keyboard-type clamping means, many tiles with uneven surfaces and uneven thickness can be arranged in a row and securely fixed. Can be. Therefore, there is an effect that the tile of the split skin can be cut accurately. In addition, if the rotation surface of the disk cutter can be inclined at an arbitrary angle by pivotally attaching the cutting unit to the drive unit as in claim 3, the cut surface of the tile of the split skin can be formed at an arbitrary angle. Angle can be.

Further, if the distance from the contact plate to the tip of the clamp piece is made variable as in claim 2, it is possible to cope with both long tiles and short tiles widely, as shown in FIG. It is possible to handle so-called role tiles in which the ends of long and short tiles are cut diagonally and joined at right angles.

Further, the tile cutting device according to claim 4 can cut the diamond cutter even if the diamond cutter is turned in the opposite direction to the designated cutting direction, and can sufficiently withstand long-time use. Based on new knowledge,
Since the cutting unit is reciprocated and the diamond cutter is rotated forward and backward in accordance with the moving direction of the cutting unit, tiles can be efficiently cut on both the forward path and the backward path of the cutting unit.
