Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass sheet cutting machine for cutting a glass sheet using a high-pressure water stream, that is, a water jet.

[0002]

2. Description of the Related Art In a conventional glass sheet cutting machine, a cutting tool is linearly moved in two directions in a plane orthogonal to each other to position the cutting tool at a cutting portion of a glass sheet to be cut, or While moving the cutting tool in one direction in the plane, move the glass plate to be cut in the other direction in the plane orthogonal to the moving direction of the cutting tool, and cut at the cutting part of the glass plate to be cut The tool is positioned so that, for example, a thick glass sheet is cut.

[0003]

By the way, in the case of a glass plate cutting machine which uses a water jet jet head as a cutting tool, the water jet after cutting and passing the glass plate still has sufficient energy. In order to consume energy, a receiver for catching the water jet after passing through the glass plate is arranged opposite to the head. However, in a glass plate cutting machine in which a cutting tool as described above is linearly moved in two directions orthogonal to each other in a plane, the position of the water jet after passing through the glass plate is determined corresponding to the shape to be cut. Results,
The receiver also needs to be placed corresponding to the shape to be cut. Therefore, when constructing this kind of cutting machine with versatility so as to be able to cut glass sheets into various different shapes, it is necessary to place the receptor at a considerable portion within a plane defined by two directions orthogonal to each other. However, the machine becomes large-scaled and requires a large area.

Further, in the conventional glass plate cutting machine, it is difficult to shorten the cutting time because it is difficult to shorten the cutting time by providing a plurality of heads and sharing the cutting area with each head. It is not possible to obtain a large number of glass plates cut into a predetermined shape. In addition, it is difficult to provide a support mechanism that firmly supports the glass plate to be cut.

The above problems are caused by moving the cutting tool in one direction in the plane and moving the glass plate to be cut in the other direction in the plane orthogonal to the moving direction of the cutting tool to cut. It likewise occurs in a glass sheet cutting machine in which a cutting tool is positioned at the cutting portion of the glass sheet to be cut.

The present invention has been made in view of the above points, and an object thereof is to cut a glass plate in which a receiver for receiving a water jet after passing through the glass plate can be provided only in a specific region. To provide machines.

Another object of the present invention is to provide a glass plate cutting machine which can be provided with a plurality of heads, thereby shortening the cutting work time.

Still another object of the present invention is to provide a glass plate cutting machine capable of firmly fixing a glass plate and thereby accurately cutting the glass plate.

[0009]

According to the present invention, the above object is to provide a table on which a glass plate to be cut into a predetermined shape is placed, and a water jet for cutting the glass plate placed on the table.

First, the knobs 29 and 30 and the movable base 39
Etc. are rotated and moved to move the head 5 in the P and Q directions and in the X direction.
Direction, and the water jet 4 is initially set to be jetted to the initial cut portion of the glass plate 2 having the shape to be cut. When the glass plate 2 is cut in the direction orthogonal to the horizontal plane, the water jet 4 is jetted from the nozzle 18 on the extension line of the axis 9. When the glass plate 2 is cut in the orthogonal direction as described above, the turning device 10 does not have to turn the head 5.

At the same time, the water jet 4 is ejected onto the glass plate 2, and the glass plate 2 is cut into a predetermined shape by the water jet 4 mixed with the abrasive.

By the way, in the glass plate cutting machine 1 of this example, while the glass plate 2 is rotated in the R direction, the head 5 is linearly moved in the X direction so that the water jet 4 is relatively cut. Since it is moved along the glass plate 2, the opening 55 of the receiver 8 for receiving the water jet 4 after passing through the glass plate 2 and attenuating the energy of the water jet 4 may simply extend in the X direction, and thus may have various shapes. Even when the glass plate 2 is cut, it is not particularly necessary to prepare the receptacle 8 having an opening shape corresponding thereto, and it is not necessary to arrange the receptacle 8 over the entire area corresponding to the cut shape. Therefore, the machine can be downsized, and a glass plate cutting machine having a small occupied area can be provided.

The glass plate cutting machine 1 of the above-mentioned example is
Although one head 5 is provided to cut the glass plate 2 into a predetermined shape, the present invention is not limited to this, and multiple heads may be provided. That is, for example, as shown in FIG. 3, another head 70 is provided in addition to the head 5 so that the half of the predetermined shape to be cut by the head 5 and the remaining area of the head 70 are shared by the glass plate 2 and the head 5, respectively. The glass plate cutting machine 200 may be formed so as to cut the glass plate to shorten the working time.

In the glass plate cutting machine 200, a head 70 for jetting a water jet 71 to a cutting portion of the glass plate 2 to be cut, a nozzle 72 for jet jetting, and an on / off valve are used as in the head 5 side. The head 70 includes 500 kgf / cm ² to 50
Head 7 with ultra-high pressure water having a water pressure of 00 kgf / cm ^2.
0, a hose 75 for supplying the abrasive to the head 70 and a hose 76 for supplying a hydraulic pressure for controlling the on / off of the valve 73 so as to mix the abrasive with the super high pressure water.
Respectively, and connects the head 70 to the bracket 78 via an adjusting mechanism 77 that adjusts the position of the head 70 with respect to the P direction in the horizontal plane and the Q direction orthogonal to this P direction,
The adjustment mechanism 77 includes a slider 80 attached to a slider 79 so as to be movable in the P direction, and an adjustment knob 81 for adjusting the position of the slider 80 in the P direction with respect to the slider 79, and a bracket 78. The head 7 includes a slider 79 movably mounted in the Q direction and a Q direction adjusting mechanism having an adjusting knob 82 for adjusting the position of the slider 79 in the Q direction with respect to the bracket 78.
0 is attached to the slider 80 via the attachment 83, and the knob 8

For example, an air cylinder device as a pressing device is attached to the machine frame 35, and the fixing device 7 is provided at the tip of the piston rod of the air cylinder device. The glass plate 2 may be fixed to the center stand 13 by air-elastically pressing and sandwiching the glass plate between the pressing pad and the center stand 13. As described above, in the glass plate cutting machines 1 and 200, since the fixing device for pressing and sandwiching the glass plate 2 to be cut can be arranged in cooperation with the center stand 13, the glass plate 2 can be firmly fixed during cutting. , Whereby an exact cut can be made on the glass plate 2.

In addition, in the glass plate cutting machines 1 and 200,
When the glass plate 2 has an inclined cutting end surface,
The heads 5 and 77 are tilted so that the water jets 4 and 71 are ejected in an oblique direction. In this case, the water jet 4 is activated by operating the turning devices 10 and 120.
And 71 are to be jetted along the top of the curved shape.
