The cutter holder is provided to rotate through rotation support means along a scribe line, and adopts a configuration in which pressure is applied to the cutter holder in a direction opposite to the scribe direction.

(Example)

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 are side views showing the cutter holder portion of the plate glass cutter in the first embodiment, wherein the supporting member 2 of the cutter holder 1 has already been cut. Lifting means consisting of a male screw which is reversibly driven by the operation of a servo motor and a female screw which is provided on the support member 2 and inserted into the male screw (not shown in the drawing). Slide in the vertical direction.

The support of the cutter holder 1 with respect to the support member 2 is provided so as to move up and down by suitable guide means 3.

The guide means 3 is, for example, a pair of links on both sides which are installed to support both ends of the support member 2 and the cutter holder 1 as shown in FIG. link) 5 (link 5 is not limited to the upper and lower stages, but may be one stage), and, for example, as shown in FIG. 2, a longitudinal guide rail installed in the supporting member 2 (guide) In some cases, the lifter may be lifted by a slider 7 installed on the rail 6 and the cutter holder 1 and engaged to slide on the guide rail 6.

In either case, the stopper 8 in contact with the link 5 or the slider 7 determines the position at which the cutter holder 1 descends and stops.

In addition, the cutter holder 1 is provided with a vertical force by the pressing means 9.

As the above-mentioned vertical force applying pressure means 9, for example, as shown in the drawing, a cylinder 11 is installed on the mounting seat 10 of the support member 2, and the piston rod 12 of the cylinder 11 The tip is brought into contact with the upper end of the cutter holder 1 via a pole.

In addition, a cutter wheel 13 is installed at the lower end of the cutter holder 1, and the support portion of the cutter wheel 13 is inclined in the direction in which the cutter wheel 13 is to move under a scribe state (by bearing). There is an axial support 14 which is installed to rotate freely.

The inclined shaft support 14 is inclined at an angle of approximately 30 degrees with respect to the vertical axis of the cutter holder 1 in the case shown in the drawing. However, the angle is not limited and the cutter wheel 13 moves. You can determine the optimal angle.

With the above configuration, after the plate glass A is placed (supplied) on the table of the glass cutter, the table or the cutter wheel 13 is positioned directly above the scribe starting point of the plate glass A. After one of the supporting members 2 is moved, the male screw is driven by the operation of the motor, and the supporting member 2 having the female thread is moved to the plate surface of the plate glass A (the upper surface of the one shown in the drawing). After contacting and contacting the cutter wheel 13, the support member 2 is slightly moved to stop the stopper 8 from the link 5 or the slider 7, and then the movement of the support member 2 is stopped.

Then, the plate glass A is scribed with the cutter wheel 13 by traveling on either the supporting member 2 side or the plate glass side.

In the above scribe, the vertical force P (the force for pressing the cutter wheel 13 against the plate glass A) by the pressing means 9 according to the inclination of the support portion of the cutter wheel 13 and the moving force F during scribing. The force that tries to move in the normal direction N acts by the simultaneous action, and the cutter wheel 13 tries to move with respect to the surface of the plate glass A.

On the other hand, reaction force S in plate glass A acts, and the vertical force P is returned.

In this way, the amplitude motion is caused by the synergistic effect of the vertical force P, the moving force F, the normal direction N, and the reaction force S in the plate glass A, and a deep vertical crack is obtained by the ordinary cutter wheel 13. Lose.

3 and 5 are side views showing the cutter holder portion of the plate glass cutter in the second embodiment, wherein the cutter holder 1 in the first embodiment rotates along a scribe line. It is installed to rotate through 21).

As the rotation supporting means 21, as shown in Fig. 3, a long hole 22 is formed at one end of the lower link 5 in the upper and lower two-stage links 5, and the cutter holder 11 is formed in the long hole 22. The cutter holder 1 can rotate within the range of the long hole 22 through the pin 4 on the side.

As another rotation support means 21, as shown in Fig. 5, the slider 7 provided on the lifting support member 23 slides with respect to the guide rail 6 provided on the support member 2, and the lifting support is also supported. The cutter holder 1 is inserted into the vertical groove 24 formed at the front face and the lower face of the member 23 so as to rotate the upper end side of the cutter holder 1 through the pin 25 in the elevating support member 23. The cutter holder 1 can be rotated with respect to the support member 23.

And the vertical force with respect to the cutter holder 1 makes the tip of the piston rod 12 of the cylinder 11 contact the upper end of the lifting support member 23 via a ball.

The cutter holder 1 is further provided with a pressure applying means 26 which pushes in the opposite direction to the scribe direction.

As the mounting method of the pressure applying means 26, as shown in Figs. 3 and 4, the lifting member is lifted on the opposite surface of the support member 2 and the cutter holder 1, and as shown in Figs. Concave holes 27 are formed on the opposing surfaces of the supporting member 23 and the cutter holder 1, and the coil springs 28 are coupled to the concave holes 27. For example, the same purpose may be achieved by rubber, cylinder, etc.).

The inclination (axial support portion 14) in the direction in which the cutter wheel 13 under the scribe condition of the lifting means, the guide means 2, the stopper 8, the pressing means 9 and the cutter wheel 1 of the support member 2 in the second embodiment is about to move, The same description as that in the first embodiment will be omitted.

In the above-described configuration, as in the first embodiment, the force which tries to move in the normal direction N by the simultaneous action of the vertical force P by the pressing means 9 and the moving force F when scribing is applied to the surface of the plate glass A. The cutter wheel 13 is about to move.

On the other hand, reaction force S in the plate glass acts and the vertical force P is returned.

On the other hand, the pressure applying means 26 acts on the pressing force P 'according to the compression.

As a result, when the vertical force P, the pressing force P ', and the moving force F are applied, a force that tries to move in the normal direction N acts, and the amplitude movement is caused by the synergistic effect of the reaction force S and the return force P' on the plate glass A. With this action, a deep vertical crack is smoothly obtained by the usual cutter wheel 13.

According to the cutter holder of the glass cutter of the present invention as described above, since the support portion of the cutter wheel is inclined, the force to move in the normal direction by the simultaneous action of the vertical force and the moving force by the pressing means is applied to the surface of the plate glass. The cutter wheel is about to move.

In response, the reaction force in the glass acts to return the normal force.

This causes amplitude movements due to the synergistic effects of vertical force, movement force, normal direction, and reaction force on the plate glass, resulting in a deep vertical crack by a normal cutter wheel, which, as is known, causes a significant increase in the price of the device. No special machining wheels or vibration generators are required.

In addition, the cutter holder is installed to rotate through the rotation support means along the scribe line, and the cutter holder is provided with a pressure to push the cutter holder in the opposite direction to the scribe direction. A force trying to move in the normal direction acts and the cutter wheel tries to move with respect to the face of the plate glass.

On the other hand, in addition to the reaction force in the glass to return the normal force, the pressure is compressed according to the movement of the cutter wheel, and the return force due to the compression acts. By this, deep vertical cracks are smoothly obtained.
