Generally, the wide chamfering (beveling) process includes the edge polishing process (edge cutting or edge grinding), chamfer cutting (bevel cutting with a diamond hole), and chamfer grinding (smoothing with a grindstone, etc.) to grind the chamfered surface. ,
It is necessary to go through various processes such as a polishing process to polish the chamfered and ground surface.

However, in each of these processes, it is necessary that the machining head, and ultimately the machining wheel, be provided with mechanical coordinate axes so as to run along the edge of the glass plate, and each of these axes must be numerically controlled.

By the way, in order to control all of the above-mentioned processes, there are many control axes, a large number of numerical control devices are required, a multi-layer high-level numerical control device is required, and the program for making control tape [1 gram is complicated, It becomes difficult.

Therefore, the present invention eliminates the mechanical connection of a large number of complicated control axes that govern the machining of each process, and allows simultaneous numerical control of the working motion of each process using a single or a small number of numerical control devices. .

Of course, the upper and lower limits of the conveyor device 10 are set by limit switches. Furthermore, the belts it and It for feeding the glass plates are sent by an accurate distance by an automatic control motor 1G, but this automatic control motor 16 is normally controlled by a numerical control system using the control tm axis (fourth axis) of a numerical control device. by. That is, a numerically controlled servo motor using one axis from a numerically controlled device is used.

That is, the slide stand 27 is attached to the curved surface of the cross stand 7,
The slide 28 is attached to the processing head stand 6, and the slide 2
8 is held on the slide stand 27 and moves linearly.

Each of the X-axis processing heads 5 is attached to a processing head stand 6 via a turning device 8, and is held by the processing head stand 6 so that it can freely rotate horizontally.

A plurality of, for example, five, processing heads 5 are installed on the processing head stand 6, and are arranged in rows in the order of process: an etching head 5B, a bevel cutting head 5A, a smoothing head 5C, and a polishing head 5D.

The etching head 5B simply controls the cutting or grinding (also referred to as edge grinding) of edges (end faces), and performs cylindrical cutting and grinding using a flat diamond wheel.

The bevel cutting head 5^ is in charge of chamfer cutting, and a cup type diamond wheel covers the glass plate and performs bevel grinding in an inclined position.

The smoothing head 5C performs bevel-cut surface grinding (also referred to as smoothing or abrasive),

Each turning device of the bevel cutting head, smoothing head 3C, and polishing head 3D uses the Z axis perpendicular to the linear control tII@XY as the rotation axis (C axis), so that these turning devices are collectively numerically controlled. The respective pivot shafts are collectively connected to a servo motor (C-axis control) at the upper part via a transmission means such as a bevel gear train shaft.

Axis of each of the above rotating devices (C axis, i.e. FIL@center line)
As shown in FIG. 4, each passes through a bevel cutting point P1, a bevel grinding point P, and a polishing point P, where etching is currently in progress.

Therefore, each wheel horizontally rotates around these current bevel cutting points P1, bevel grinding point P, and polishing point P (numerically controlled according to the shape change of the glass edge), and changes the shape of the glass plate edge. Regardless of the changes, each wheel should be cut, ground and polished while keeping the angle of cutting and grinding always the same. That is, each wheel should be centered around the cutting and grinding area as needed. While spinning under numerical control, cutting, grinding, and polishing are carried out.

The above numerical control method for the swing device may use, for example, linear-circular combined interpolation that combines linear interpolation and circular interpolation as programming.

That is, while performing the XY plane arc complement 11M, the rotation of the C axis is numerically controlled in proportion to the rotation angle of the arc.

To perform the chamfering process, first move the conveyor system @ 10 up and set the glass plate in the first processing section 9, then process the conveyor system 10, operate the vacuum pump, etc., and place the glass plate 1 on the fixing table 2. Fix it by suction.

Next, the numerical control device is operated to numerically control the entire processing section 9. At this time, only the first processed portion is processed.

When one cycle of operation is completed, the glass plate is separated from the fixed table at the same time as the conveyor 1vilo is moved up, and the glass plate is sent to the next processing section. The same movements are performed below, and the world processing is performed sequentially.

Once sent to the processing department, the processing (numerically controlled processing) is completed by the receiver. Therefore, the glass plate is transported by the conveyor device 10.
Sequentially - It is efficient because it is made into a straight line and sent to successive processing sections where it undergoes different processing and is finished. In addition, since the plurality of processing heads 5 are mechanically connected to perform simultaneous motion operations, automation can be performed using a single numerical control device.
Be efficient.

9 is non-coaxial, and one processing head 5 is a slide device capable of moving the processing wheel 37 in the - plane including the first and second directions with respect to the direction of cutting into the glass plate 1. It has 32. As described above, since the numerically controlled glass plate processing machine of the present invention has the configuration described above, the plurality of work heads are simultaneously controlled by the number (n data) and a series of glass plates are processed continuously at P4. [Application of the working tools mounted on each of the working heads]: Even if the relative positions of the working tools to the glass plate to be moved change depending on the working conditions, for example, due to wear, the relative positions of the working tools become uneven. The moving device can move each of the f'l work tools in the cutting direction and reposition them to the initial predetermined positions, and the relative positions of different work tools can be adjusted by moving each work tool individually. can be set at the optimal position,
Therefore, the processing of the glass plate is continuously repeated while maintaining the same relative position conditions without modifying the numerical data each time. 4.
