FIELD OF THE INVENTION The present invention relates to a cutter device, especially glass.
The present invention relates to a cutter device for cutting a plate or breaking a glass plate.

[0002]

2. Description of the Related Art From a raw glass plate to a window glass for a building,
When manufacturing window glass for automobiles, etc., in order to make the raw glass plate into a predetermined shape, a score line (main score line) along the predetermined shape is formed on the raw glass plate, and this main score line is formed. A glass plate splitting device that forms an end cutting line (auxiliary score line) on a glass plate on which is formed and also pushes the glass plate along the main score line and the auxiliary score line (hereinafter simply referred to as score score lines) Used. And such a glass plate breaking device is provided with a cutter device for forming a score line, and this cutter device has a mechanism for pressing the cutter blade against the glass plate or separating it from the glass plate. There is.

[0003]

By the way, in the conventional cutter device, when a mechanism for pressing the cutter blade against the glass plate or separating it from the glass plate is embodied by, for example, a pneumatic cylinder device, a score line is being formed. In, the aeroelastic force of the pneumatic cylinder device preferably acts on the cutter blade to form a desired score line, but at the start of score line formation or at the time of score line formation, the cutter blade may be pressed against the glass plate. It is relatively difficult to position the cutter blade when separating it from the glass plate, and especially when the cutter blade is lowered and pressed against the glass plate, the pneumatic cylinder device causes the cutter blade to collide with the glass plate and collide with the glass plate. It may cause cracks and chips.

[0004] The present invention was made in view of the above-described aspects, and its object, in descending mosquito jitter blade, it is possible to eliminate the excessive collision of the cutter blade to the glass plate, the cutter blade can be pressed against the glass plate with the elastic force of Nozomu Tokoro, cracked Thus, there is provided a cutter device capable of producing a glass sheet product with no chipping.

[0005]

According to the present invention, the object is to provide a base, a slider mounted on the base so as to be vertically movable, and a slider moving device for moving the slider up and down.
An elastic force generator mounted on the slider, a rotatable shaft connected to the elastic force generator so as to receive the elastic force from the elastic force generator, a shaft rotating device for rotating the shaft, and a shaft. And a cutter blade attached to the shaft, and the shaft rotating device includes an electric motor arranged concentrically with the shaft. The electric motor is splined to the shaft and arranged concentrically with the shaft. This is achieved by a cutter device that includes a rotor and a stator that is fixed to the base and that is arranged concentrically with the shaft.

[0006] In such a mosquito jitter device, in one preferred embodiment of a slider moving apparatus, an electric motor provided in the base, and a screw shaft provided rotatably screwed to the slider in the base And a rotation transmission mechanism connected to the screw shaft and the output rotation shaft to transmit the rotation of the output rotation shaft of the electric motor to the screw shaft.

When the elastic force generating device is embodied by a pneumatic cylinder device that generates a pneumatic elastic force, one end of the piston rod of the pneumatic cylinder device may be connected to the shaft. In this case, when one end of the piston rod of the pneumatic cylinder device and the shaft are connected via a bearing mechanism so that they can rotate relative to each other, the rotation of the shaft is not transmitted to the piston rod and is connected to the piston rod. Unnecessary wear of the seal ring of the piston of the pneumatic cylinder device can be avoided. As the elastic force generator, instead of or together with the pneumatic cylinder device,
It may be embodied by a coil spring device.

In one example, the rotor is coupled via a ball spline mechanism and is concentric with the shaft,
The ball spline mechanism includes spline grooves formed on the rotor and the shaft, respectively, and a large number of balls fitted in the spline grooves.

[0009]

[Action] In mosquito jitter apparatus of the present invention, slider actuation of slider moving apparatus is lowered, lowering of the slider is transmitted to the shaft via an elastic force generator. At the same time when the shaft is lowered, the cutter blade is also lowered, so that the cutter blade is brought into contact with the glass plate. For example, during the formation of the score line, the cutter blade is pressed against the glass plate by the elastic force of the elastic force generator, whereby the score line is formed on the glass plate. The cutter blade is directed in the direction in which the score line is to be formed by the rotation of the shaft by the shaft rotating device. When the formation of all the score lines is completed, the slider moving device is operated again to raise the shaft and the cutter blade, and the cutter blade is separated from the glass plate to a predetermined position.

The present invention will now be described in more detail based on the preferred embodiments shown in the drawings. The present invention is not limited to these specific examples.

The base 1 is moved in the X direction (FIG. 1) in a plane parallel to the surface of the glass plate 80 by an XY moving device (not shown).
(The direction perpendicular to the paper surface of FIG. 2) and the Y direction orthogonal thereto. Therefore, when the base 1 is moved in the XY direction, the cutter blade 7 is also parallel to the surface of the glass plate 80. Within, i.e. in the XY direction.

Cutter device 100 formed as described above
When, for example, a score line is formed on the glass plate 80 by the above, first, the slider moving device 3 is started when the score line is formed.

As described above, in the cutter device 100, the cutter blade 7 is lowered and raised by the slider moving device 3, and the cutter blade 7 is elastically pressed against the glass plate 80 by the pneumatic cylinder device 35. Therefore, it is possible to prevent a situation in which the cutter blade 7 collides with the glass plate 80 when the cutter blade 7 descends, and it is possible to manufacture a glass plate product having no cracks or chips. That is, if the pneumatic cylinder device 35 also causes the cutter blade 7 to descend and rise, the cutter blade 7 may collide with the glass plate 80 when the cutter blade 7 descends, but in the cutter device 100, such a possibility may occur. The cutter blade 7 can be precisely positioned with respect to the glass plate 80.
