Description

Description: TECHNICAL FIELD The present invention relates to a glass cutting machine for strips, and more particularly to a scriber and a scriber for scribing a glass plate and a breaker for cutting a scribed glass plate. The present invention relates to a body-shaped glass cutting machine.

<Conventional Technology> When a conventional glass plate is cut, it is common to make a scribe line on the glass plate with a scriber, and then cut along the scribe line with a breaker, which is another machine.

<Problem to be Solved by the Invention> In the conventional example as described above, the scriber and the breaker are separate machines, so the work is also separate work. Need time.

 Occasionally, it may take days to organize a process.

As a characteristic of ordinary glass, if a glass plate is left with a scribe line attached, cracks will progress from the scribe line in the direction of the surface of the glass. Is easy to occur,
There is a problem that the quality of the cut surface of the glass plate is deteriorated.

Further, since two machines, a scriber and a breaker, are required to cut the glass plate, there is also a problem that the installation space of the machines becomes large.

<Means for Solving the Problems> The present invention integrates a scriber and a breaker,
Further, by arranging the work feeding unit and the transport unit, the scribe to the glass plate and the cutting of the glass plate are performed in one process by one machine, so that the quality of the glass cut surface can be improved and An object of the present invention is to provide a glass cutting machine capable of reducing the installation space of the machine.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing an embodiment of a glass cutting machine of the present invention, and FIG. 2 is a schematic sectional side view of FIG.

In the figure, reference numeral 1 denotes a main body of a glass cutting machine, in which a power source and a control device for driving the glass cutting machine are built.

Reference numeral 2 denotes a mounting table provided on the upper surface of the base 1, and is configured such that when the glass plate is placed, the glass plate is fixed by vacuum suction or the like.

Reference numeral 3 denotes X on one end side of the mounting table 2 along the guide rail 4.
This is a scribe unit for making a scribe line on a glass plate slidably arranged in the direction, and the slide range in the X direction is regulated by the position detection sensors 5, 5 '.

Reference numeral 6 denotes a break unit disposed on the side surface of the stage 2 along the guide rail 7 so as to be slidable in the Y direction. Reference numeral 8 denotes an other end of the stage 2 slidably disposed in the Y direction. This is a work feed unit, which is controlled so as to be able to feed a predetermined amount of pitch by clamping an end face of a glass plate placed on the stage 2.

9 is a program loader for inputting and instructing the pitch feed amount of the work feed unit 8, and 10 is an operation panel for operating the glass cutting machine.

Reference numeral 11 denotes a transport unit, which is configured to automatically transport a glass plate cut to a predetermined width by a belt conveyor or the like and to a predetermined container (place) as described later.

In the present embodiment, the transport unit 11 is provided at the rear of the glass cutting machine. However, this installing location is arbitrarily installed in a place with good workability due to the layout of the installation location of the glass cutting machine. Needless to say, it may be removed if unnecessary. In the present invention, the break unit is slidable in the Y direction along the guide rail 7 in the present invention. However, the break unit does not hinder the operation of the scribe unit. Any configuration is acceptable.

Next, an operation of cutting a glass sheet by the glass cutting machine according to the embodiment of the present invention will be described.

First, after the glass plate is placed at a predetermined position on the stage 2, the work feed unit clamps the work, moves in the Y direction by a predetermined pitch, and places the glass plate on the stage by means such as vacuum suction. Fix to 2. When the fixing is completed, the scribe unit 3 moves along the guide rail 4 and starts to make a scribe line on the glass plate. When the scribe unit 3 moves while applying a scribe line to the glass plate and comes into contact with the position detection sensor 5, the scribe unit 3 is stopped by a signal from the position detection sensor 5.

Next, the break unit 6 moves along the guide rail 7 according to the signal of the position detection sensor 5 and stops when the break head of the break unit 6 moves to the above-described scribe line position. Disconnect. Although not shown, the stop position of the break unit 6 may be set by using a positioning sensor, or the movement amount may be set in advance.

When the glass plate is cut by the break unit 6,
Although not shown, the break unit 6 is reversed by a disconnection completion signal (the completion of the operation of the break head of the break unit 6 is detected and a signal may be generated, or another means may be used) built in the break unit 6. Move in the direction and stop at the original position.

Subsequently, the scribe unit 3 moves in the reverse direction, contacts the other position detection sensor 5 ', and stops. When the scribe unit 3 stops at the original position, the work feed unit 8 is activated by a stop signal (not shown), and feeds the glass sheet backward (Y direction) by a pitch amount set in advance by the program loader 9.

When the pitch feed is completed by the set pitch amount, the feed is stopped there. The stop signal activates the scribe unit 3, and the glass plate is automatically cut to a predetermined width by repeating scribe → break → pitch feed sequentially. .

Further, the glass plate cut into a predetermined width is transported by the transfer unit 11.
Is sent to a predetermined container (place).

In addition, as a method of sending the cut glass plates to the transfer unit 11, the glass plates sent by the work sending unit 8 may be received on a belt conveyor of the transfer unit 11, or one by one using a robot or the like. It may be taken out and sent to the transport unit. Furthermore, the transport unit
The robot 11 itself may be configured as a robot, and may be carried one by one to a predetermined container (place), which is free for the designer.

<Effects of the Invention> As described in detail above, according to the glass cutting machine of the present invention, the scribe unit, the break unit, the work feed unit, and the transfer unit are constituted by one machine, so that the scribe to the glass plate is performed. It has become possible to continuously perform a process of attaching a line, cutting, feeding a pitch by a predetermined glass width, and sending the cut glass plate to a predetermined container (place).

As a result, the time difference between the step of applying a scribe line to the glass plate and the step of cutting the glass plate along the scribe line is shortened, and the glass cut surface is free from shavings, frays, etc., and the squareness of the cut surface is reduced. , Bending and the like can be minimized, and the quality is very stable.

Further, since the cutting of the glass plate can be performed by one machine, there is also an effect that the installation space can be reduced.
