Brittle material brake device and brittle material brake method {BRITTLE MATERIAL BREAKING APPARATUS AND BRITTLE MATERIAL BREAKING METHOD}

The present invention relates to a brittle material brake device and a brittle material brake method capable of braking the lateral portions of the brittle material by continuously moving even a brittle material such as a glass plate in which a scribe line is formed substantially parallel to the moving direction.

After the scribe line is formed on a plate-shaped brittle material such as a glass plate, the brittle material can be braked along the scribe line by applying a predetermined weight to the brittle material.

For example, Patent Literature 1 discloses a brake that can move a blade operated by an actuator driven by a servo motor or the like up and down to cut brittle material such as a glass plate on which a scribe line is formed without any cracks, and skillfully cut it. An apparatus is disclosed. The brittle material is cut along the scribe line by moving the blade to a predetermined position and stopping by a slide table, and driving the blade downward in a fixed state.

However, in the brake device disclosed in Patent Document 1, it is necessary to stop and fix the brittle material once at the time of braking. Therefore, there is a problem that it is difficult to shorten the time required for the brake process as the number of glass plates to be braked increases in that it cannot continuously brake.

In addition, in order to brake correctly, it is necessary to precisely align the scribe line and the blade, and the mechanism of the entire apparatus becomes complicated and the cost becomes high, such as correcting the position by separately providing a positioning sensor such as a camera. There was also a problem.

It is done.

In addition, the brittle material brake device according to the second invention includes a sensor for detecting the presence of the brittle material in the first invention, and while the sensor detects the presence of the brittle material, It is characterized by being pressed down to the said brittle material side.

Moreover, in the brittle material brake apparatus which concerns on 3rd invention, in the 1st or 2nd invention, the said scribe line is formed in the surface of the said press roller side of the said brittle material, It is characterized by the above-mentioned.

Next, in order to achieve the above object, in the brittle material brake method according to the fourth invention, a plurality of moving rollers holding the brittle material from both sides is arranged in the moving direction of the brittle material, and is continuously moved by the moving roller. A brittle material braking method for braking a brittle material along a scribe line formed on a surface, wherein a width of the brittle material is wider than an interval in a direction substantially orthogonal to a traveling direction of the brittle material of the moving roller, The scribe line is formed at one end or both ends positioned outside the moving roller substantially in parallel with the advancing direction of the brittle material, and the scribe line outside the position where the moving roller contacts the brittle material by a pressure roller. On one or both ends of the formed brittle material It is possible to pressurize, and while the said brittle material exists in the area | region moved by the said some moving roller, it is characterized by pressing down the said press roller to the said brittle material side.

EMBODIMENT OF THE INVENTION Below, this invention is demonstrated in detail based on drawing which showed the embodiment. In the following description, the brittle material to be subjected to the brake is a glass plate, and scribe lines are formed in advance by a known scribe line forming apparatus or the like.

BRIEF DESCRIPTION OF THE DRAWINGS It is a side view seen from the rotating shaft direction of the moving roller which shows typically the structure of the brittle material brake apparatus which concerns on embodiment of this invention. As shown in FIG. 1, the brittle material brake device according to the present embodiment continuously moves a plate-shaped brittle material, for example, a glass plate 11, in the direction of an arrow 12. The glass plate 11 is pinched from both surfaces by a pair of upper movement roller 13 and lower movement roller 14 from a plurality of places, and the plurality of upper movement rollers 13, 13,... And lower movement roller 14, 14, ...) to move.

Two scribe lines are formed in the glass plate 11 along the moving direction. 2 is a plan view of the glass plate 11 showing a state of forming a scribe line. As shown in FIG. 2, two scribe lines 18 and 18 that are substantially parallel to the moving direction 12 are formed at both ends of the glass plate 11.

The pressure rollers 15 and 15 for returning to FIG. 1 and brake the glass plate 11 are the side of the advancing direction of the glass plate 11, and are arrange | positioned outside from the scribe lines 18 and 18. As shown in FIG. The pressure rollers 15 and 15 are located at a position slightly away from the position in which the glass plate 11 travels, rather than a position where the plurality of upper movement rollers 13, 13,... And the lower movement rollers 14, 14,... Is placed.

3 is a movement of the glass plate 11 which shows the positional relationship of the glass plate 11, the upper movement rollers 13, 13, ..., the lower movement rollers 14, 14, ..., and the pressure rollers 15 and 15, respectively. It is the front view seen from a direction. As shown in FIG. 3, the glass plate 11 is clamped from upper and lower sides by the upper moving rollers 13, 13, ..., and the lower moving rollers 14, 14, .... And the scribe lines 18 and 18 are formed along the advancing direction of the glass plate 11 on the upper surface of the glass plate 11. The scribe lines 18 and 18 are formed outside the position clamped from the upper and lower sides by the upper movement rollers 13, 13, ..., and the lower movement rollers 14, 14, ....

The pressure rollers 15 and 15 are arranged further outside than the scribe lines 18 and 18. When the pressure rollers 15 and 15 are pushed down by arrange | positioning in this way, the bending moment in the direction which pushes outward arises in the both ends of the glass plate 11, and the glass plate 11 along the scribe lines 18 and 18 is carried out. Can brake.

4 is a front view seen from the moving direction of the glass plate 11 when the pressure rollers 15 and 15 are pushed down. By pressing down the pressure rollers 15 and 15 as shown in Fig. 4 (arrow direction), the glass plate 11 is braked along the scribe lines 18 and 18, and the broken pieces fall downward and are recovered. .

The timing for pushing down the pressure rollers 15 and 15 is pushed down at least in a state where the front end portion of the glass plate 11 is located directly under the pressure rollers 15 and 15, and the rear end portion of the glass plate 11 is pressed by the pressure roller ( It is enough to return to the original position when passing through 15, 15). In order to control the vertical movement of the pressure rollers 15 and 15, the sensor 21 which detects whether the glass plate 11 has passed, the actuator 22 which moves the pressure rollers 15 and 15 up and down, and a sensor The control apparatus 23 which transmits the instruction | command signal of an up-and-down motion to the actuator 22 based on the signal detected by 21 is provided.

The sensor 21 is, for example, a photoelectric sensor, and is preferably a regression type photoelectric sensor capable of detecting the presence or absence of a transparent material such as the glass plate 11. The sensor 21 detects the presence of the glass plate 11 when the glass plate 11 is in a state of being pinched from the top and bottom by the upper moving rollers 13, 13,... And the lower moving rollers 14, 14,... It is so that the advancing direction side of the glass plate 11 is larger than the upper movement rollers 13, 13, ..., and the lower movement rollers 14, 14, ..., and is arrange | positioned in the substantially center of the width of the glass plate 11. Moreover, the position where the center of the up-down movement of the press roller 15 and 15 and the position which the sensor 21 detects substantially correspond, or the position which the sensor 21 detects is arrange | positioned in the position of the front of the advancing direction of a glass plate. It is desirable to install. In this way, a part of the glass plate 11 necessarily exists immediately below the pressure rollers 15 and 15 at the time when the sensor 21 detects the presence of the glass plate 11.

And when the sensor 21 detects the presence of the glass plate 11, the control apparatus 23 transmits an instruction signal so that the pressure rollers 15 and 15 may be pressed down on the actuator 22. As shown in FIG. The actuator 22 is a servo motor or the like, and pushes down the pressure rollers 15 and 15 by a predetermined amount in accordance with an instruction signal.

When the pressure rollers 15 and 15 are pushed down, it becomes the state of FIG. 4, and when the glass plate 11 is moved to the position where the pressure rollers 15 and 15 exist, the glass plate 11 brakes along a scribe line. do. By continuously moving the glass plate 11 in that state, it breaks along a scribe line one by one without performing especially complicated operation control, such as alignment.

When the sensor 21 detects that the glass plate 11 does not exist, the control device 23 transmits an instruction signal to raise the pressure rollers 15 and 15 to the actuator 22. The actuator 22 pulls up the pressure rollers 15 and 15 to their original positions in accordance with the instruction signal. That is, at the time when the sensor 21 detects that the glass plate 11 does not exist, the brake process is already completed, and the pressure rollers 15 and 15 are pulled up until the next glass plate 11 is moved. The braking process can be carried out continuously.

On the other hand, in order to return to FIG. 1 and to perform a brake process smoothly, the support rollers 16 and 16 paired with the pressure rollers 15 and 15 were provided, respectively, and the pressure roller 15 and the support roller 16 were supported. ) Is preferably connected with a flat belt 17 or the like. Similarly, in order to make the movement of the glass plate 11 smooth, you may connect the upper moving rollers 13, 13, ... and the lower moving rollers 14, 14, ... with the flat belts 19, 20, etc., mutually.

5 is a perspective view showing a schematic configuration of a brittle material brake device according to the present embodiment when a flat belt is used. In FIG. 5, the lower moving rollers 14, 14,... And the flat belt 20 are omitted, but the glass plate 11 includes the upper moving rollers 13, 13,... And the lower moving rollers 14, 14,... It moves in the direction of the arrow 12 by the rotation of the flat belts 19 and 20 which are caught up by.

Until the glass plate 11 is detected by the sensor 21 shown in FIG. 1, the flat belts 17 and 17 hung on the support rollers 16 and 16 paired with the pressure rollers 15 and 15 respectively. ) Is not in contact with the glass plate 11 in that the pressure rollers 15 and 15 are not pushed down. And when the sensor 21 detects the presence of the glass plate 11, the pressure rollers 15 and 15 are pushed down, and the flat belts 17 and 17 are made into the glass plate by making the support point rollers 16 and 16 the rotation centers. It is pressed down diagonally with respect to (11). And it functions so that the both ends of the glass plate 11, ie, the part which is outside from the part in which the scribe lines 18 and 18 are formed, can be pressed down sequentially from the front end of a movement direction.

By pressing down both ends of the glass plate 11 by the flat belts 17 and 17 in this way, not only the bending moment when braking with the pressure rollers 15 and 15 but also the shearing force can be imparted. It becomes possible to break along the scribe lines 18, 18.

As described above, according to the present embodiment, the pressure rollers 15 and 15 are pressed down or the flat belts 17 and 17 are pressed down to be surely bent at both ends of the scribe lines 18 and 18. Moments can be applied or shearing forces can be imparted along the scribe lines 18 and 18, making it possible to reliably brake along the scribe lines with a simple mechanism without precise positioning. Moreover, since it can brake without stopping the glass plate 11, it becomes possible to greatly shorten the time required for a brake process.

In addition, the brittle material is not limited to the glass plate 11, and any kind of brittle material may be formed as long as it is a brittle material that forms a scribe line when it breaks, and then performs a break step with high accuracy. Moreover, the kind of sensor 21 is not specifically limited, either, Any sensor which can detect the transparent glass plate 11 etc. may be sufficient. It goes without saying that various modifications, substitutions, and the like are possible within the scope of the gist of the present invention.
