JPS5836938A - Scoring device for glass plate - Google Patents

Abstract

PURPOSE:To provide a titled device which scores a glass plate approximately uniformly over the entire width while suppressing the generation of rubbing flaws over the entire width by providing a rotary supporting means which rolls on the rear surface of the glass plate along the travelling route of the scoring device in synchronization with the traveling of said device below the glass plate right under the scoring means provided on the front surface of the glass plate. CONSTITUTION:When a glass plate G traveling on ring rolls 1 comes to a prescribed position, a disclike scoring device 2 is moved downward onto one end part S1 on the plate G and while the plate G is held pressed with the tooth tip thereof, the means is rolled and run along the traveling line 3. On the other hand, while a rotary supporting means 4 provided in the position having a micro-spacing P downward from the rear surface of the plate G in the state wherein the means is fixed in the vertical position is kept located right under the means 2 at all time, the means 4 is run in synchronization with the traveling of the means 2 at the same speed as the traveling speed thereof. The spacing P is the size at which the plate G deflected by the pressure of the means 2 can be received by the means 4. When the traveling up to the other end S2 of the plate G is finished, the means 2 is moved upward to detach the same from the glass surface.

Description

[Detailed description of the invention] Primary cutting #fr in continuously conveyed glass ribbon
At Vc, the glass J moving on the conveyor roll runs on the surface of the ribbon in the direction of a cutter, which is called a cutter. A cutter runs in the width direction on the glass surface, which is brought to a predetermined position and is stationary, to create cuts in the width direction. Glass conveying means usually consists of a large number of conveying rolls that are driven in parallel. JR feeding rows have cylindrical rolls and ring rows.
However, mirror layer blanks and electronic equipment are especially sensitive to scratches on glass surfaces! In equipment for cutting glass for parts, ring rows, which have a small contact area with the glass surface, are often used from the viewpoint of preventing the occurrence of sliding. With a cutting device that uses a ring reel, the bottom surface of the glass is cut on the glass surface where it is supported by the ring and where it is not. - runs while applying a predetermined load, so if the glass is thin and has a small thickness, the glass will bend in places that are not supported by the ring.
Therefore, the cutter travels while repeating small upward and downward movements at the pitch of the ring (see Figure 8).The light cannot follow this upward and downward 1aK load, and the load applied to the tips of the cutter teeth changes. Since it is not possible to provide uniform cutting lines in the width direction of the glass, the sheet glass cannot be broken along the cutting lines when the glass is broken, and so-called cutting loss occurs frequently.

(9) If the load applied to the cutter is too hot to ensure that the cut line is applied, if the glass is thin, the cutter will easily break through the glass, creating so-called "discount tLa".
As a countermeasure against the above-mentioned cut cracks and side splits, a cylindrical socket is always installed under the cutter running line, so that the shoulder surface is in contact with the lower part of the cutter.
In the case of K-type holes, scratches occur on the bottom of the glass 11 (due to glass powder adhering to the surface).

It is an object of the present invention to rationally solve such problems and to make it possible to apply a uniform cut line on a hit while suppressing the generation of scratches and reducing the digging force.

The device for imparting zero cut lines to a glass plate according to the present invention applies cut lines to the surface of a glass plate (by running across the glass plate conveyance path from the outer edge of one gas plate to the horizontal narrow side JIK). In the case where a tool is provided, the glass plate J is placed below the glass plate directly under the cutting score imparting tool while receiving the glass plate.
[The rotary support tool that rolls on the surface is provided so that it runs along the travel route in synchronization with the travel of the cut score imparting tool at the same speed or almost the same speed as the zero travel speed.

That is, when not performing the scoring action, the rotary support tool is kept in a state separated from the back surface of the glass plate in the same way as the cutting tool (not only during standby at the home position, but also when the home position (including during the return movement to V＠￥), there is no need to create scratches on the back of the glass plate in this area). Note that the separation during standby may be one degree below the glass. It can also be placed outside the edge of the beach.

When I perform the incisor imparting action, I am, and only at this time @
Then, the rotating support supports the glass plate at the part K where the incision is applied. Since this support portion is displaced in accordance with the movement and ff of the incisor and rotational support, the contact area at each instant is an extremal value.

Therefore, it is possible to apply a uniform cut line in one hit while suppressing the occurrence of scratches to a minimum of 11.

Embodiments of the present invention will be described below.

As shown in Figure 11 or Figure 1, ring row A/(1
) When the glass plate O (in the case of this figure, a continuous glass ribbon) that is being conveyed is in the specified position, it will click! - Also called a disc-shaped cutting tool (one end of the glass plate
f) K descends and holds the glass plate part with the tips of the teeth and travels along the traveling line (1) K in the light state ゛1w1@support (4
) is installed in a fixed vertical position at the position where the cutter (3) is placed below the surface of the glass plate, and while always maintaining the position directly below the cutter (■), It travels at the same speed as the traveling speed.The minute gap (g) is the size where the glass plate (-) bent by the pressure of the descending cutter is received by the support (4).Other than the glass plate part When the cutter has finished traveling to the edge (IIm), the cutter rises and separates from the glass surface. Along with this, the deflection of the glass plate also returns to its original state, and the support A becomes horizontal.
It is separated from (4) by a minute gap (9).

By shifting the position of the running center line 111 of the support (4) by a slight distance (d) either forward or backward from the cutter running line (3), the impact when the cutter (K or P cutter) falls on the glass surface is softened. 4 hours when the glass no longer breaks through.
Moreover, the life of the cutter itself is also extended. (d) is 700%
The following is good, ko~30% is 11N! The running center line (11) and the running line (3) are parallel to each other. This cutter is a diagonal cutter.

The glass plate conveyance shield has a closing angle of inclination so that the cutting line is applied to the glass plate during conveyance in the direction that intersects the side edges of the glass plate. Stay connected.

The optical glass plate set with cut lines is breaking low A'
+Ill K breaks at the incision muscle.

Of course, the present invention is limited to the above-mentioned oblique cutter and is not limited to the above-mentioned diagonal cutter. It can also be applied to a secondary device that applies cuts in the width direction when the glass is stopped while being conveyed intermittently. An example of this is shown in Figure 6.
In this case, cutter (ri), support (
The running direction of 4) is determined to be orthogonal to the glass plate conveyance direction.

When cutting lines are to be applied to a glass plate being transported, it is desirable to drive and rotate the support so that the cutting edge of the support is equal to the transport speed. However, it may be in an idling state and can be rolled in a following direction. If the single rotation support (4) has a rotational axis perpendicular to the traveling direction, it must receive force from the glass plate in the conveying direction. become. Therefore, the omnidirectional angle K[! 1fE
It is desirable to use flexible spherical rollers (see Figure 6).

In the case of a direct cutter, this is not @9.

In the case of Figure 7, OK deflection of the glass plate is not determined.

That is, the rotation support (4) is waiting on the outside of the glass plate, and its height is exactly mKIII below the back of the glass plate when it moves horizontally. It is at a height that can be touched.

The synchronized cover (illustration may also be set at a height that just touches the top surface of the glass plate and creates a cutting line when it moves horizontally.
However, when returning, the former shall be lowered and the latter shall be raised so as to be away from the glass surface.
