Description

  The present invention relates to a glass plate processing apparatus for cutting a glass plate for window glass of an automobile, a glass plate for other uses, etc. from a base plate glass plate and grinding a peripheral edge.

  In addition, the present invention connects a glass plate scribing device / folding / dividing device and a grinding device via an adsorption conveyance device, and supplies the glass plates continuously cut from the scribing device to the grinding device one after another. Further, the present invention relates to a glass plate processing apparatus that continuously grinds and takes out one after another.

  Furthermore, the present invention relates to a glass plate processing apparatus in which a scribe portion, a folding portion, a grinding processing portion, and a glass plate conveying device are operated under NC control.

  A glass plate processing apparatus is known from Patent Documents 1 and 2.

Japanese Examined Patent Publication No. 6-75819 Japanese Patent Laid-Open No. 8-231238

  The glass plate processing apparatuses described in Patent Documents 1 and 2 both connect the split-splitting device and the grinding device via an adsorption conveyance device, and sequentially grind the glass plates cut out continuously from the scribe device. It is supplied to the apparatus, continuously ground, and sequentially taken out.

  However, in such a processing apparatus, since there is only one work table corresponding to the grinding head, the grinding head separates from the work table every time grinding of the glass plate supplied and held on the work table is completed. Return to the point and stop waiting. When the work table glass plate is unloaded and the next glass plate is received, the grinding head advances toward the work table and starts grinding. As described above, every time the glass plate of the work table is delivered, the grinding process is interrupted, and the production speed cannot be increased.

  An object of the present invention is to provide a glass plate processing apparatus that eliminates the above-described defects and has a high production speed.

  At the grinding position, the grinding head fixed to the side of the glass plate conveyance path and the grinding plate fixed toward the conveyance path are arranged in series parallel to the glass plate conveyance direction, and the angle control rotation and the glass plate conveyance are performed independently of each other. Two grinding work tables that perform X-axis movement parallel to the direction and Y-axis movement perpendicular thereto, and the two grinding work tables alternately advance to corresponding positions of the grinding head, Plane polar coordinate movement is started, one grinding work table holds the glass plate and the grinding head and polar coordinate grinding work, while the other grinding work table moves away from the grinding head to carry out the glass plate, the next glass plate This is a glass plate processing apparatus in which the receiving operation is alternately repeated, and the grinding head continues grinding.

  In addition, two grinding work tables that are disposed under the glass plate conveyance path and rotate independently of each other by plane angle control are arranged along the conveyance direction independently of each other before and after the conveyance direction across the grinding head. The two grinding work tables are alternately moved to the corresponding positions of the grinding head and moved in plane polar coordinates with the grinding head, and one of the grinding work tables is made of glass. During the grinding process with the grinding head and polar coordinate control by adsorbing the plate, the other grinding work table alternately repeats the operation of carrying out the glass plate away from the grinding head and receiving the next glass plate, and the grinding head continues This is a glass plate processing device that continues grinding.

  The present invention is provided with two work tables at the grinding position, and these two work tables are NC controlled independently of each other, and are alternately moved by a common grinding head and NC controlled coordinates. Grinding is performed.

  For this reason, during the grinding process of the glass plate with one work table coordinated with the grinding head, the other work table stops at the origin and the glass plate is delivered, and the glass on the one work table is When the plate grinding process is completed, the other work table advances to the grinding head, and the grinding head continuously performs the grinding process. The grinding head alternates with the glass plates of the two worktables, and continues the grinding process continuously without stopping the grinding process. For this reason, there is no loss time and the production capacity is high.

  Further, since the glass plates of the two work tables are ground by one grinding head, there is no variation in the grinding dimensions of the glass plates of the two work tables, and the finish is constant.

  Further, since the two work tables are NC controlled independently of each other, the two work tables can grind glass plates having different sizes and shapes.

  Further, since the two work tables are moved under NC control, the glass plates can be transferred to the work table with high positional accuracy by cooperating with the glass plate transfer device that is also NC controlled and transfers the glass plates. Accurate delivery according to the contour line of grinding can be performed.
