Abstract

PURPOSE: To dispense with periodical correction for position of a positioning member by obtaining position of one edge crossing the other edge of a rectangular plate material with an edge detecting means so as to obtain the position of the rectangular plate material. CONSTITUTION: Pushing members 48, 50 abut on the upper edge 34A of a plate glass 34, and in this condition, when the plate glass 34 is pushed downward more, the lower edge 34B of the plate glass 34 contacts with reference stoppers 44, 46. A contact of an edge detecting means 42 is moved through a carrier 38 so as to abut on the plate glass 34. Movement of a shaft of the contact is thereby stopped. After the shaft is stopped, the carrier 38 is continuously moved, and a guide cylinder is moved, resisting the energizing force of a returning spring. When a micro switch arrives a stopper of the rear end of the shaft, the micro switch is turned on. At this stage, X-coordinate position of the carrier 8 is read, and the X-coordinate position of the left edge 34C of the plate glass 34 is obtained on the basis of this coordinates position.

断テーブルに載置する。Therefore, when the plate glass is cut by a glass cutting machine, the plate glass is positioned at a predetermined position by a plate glass positioning device provided on the cutting table, and then the plate glass is cut into a desired shape by a cutter of the glass cutting machine. In the conventional glass cutting machine, the positioning device projects from the cutting table that serves as the sheet glass conveying path. Therefore, when the sheet glass is slid, the protrusions become obstacles and the sheet glass cannot slide from the sheet conveying path to the cutting table. Therefore, the plate glass is adsorbed in front of the positioning device by using an adsorbing device or the like, and the adsorbed plate glass is lifted and placed on the cutting table from above the cutting table.

テーブル１６の表面上に突出する。As described above, in the conventional positioning device, the plate glass cannot be automatically slid from the conveying path to the cutting table, so that there is a problem that productivity cannot be improved. In order to solve this problem, the applicant of the present application has proposed a positioning device shown in FIG. 9 in Japanese Patent Laid-Open No. 3-32540. According to this positioning device, when the front surface 10A of the plate glass 10 conveyed in the direction of the arrow A from the conveyance path comes into contact with the first pressing member 12, the first pressing member 1
2 rotates around the pin 14 and is pushed downward from the surface side of the cutting table 16. The pressed first pressing member 12 automatically protrudes onto the surface of the cutting table 16 after the plate glass 10 passes through.

動するので生産性が向上する。Then, the first pressing member 12 protruding above the surface is moved in the direction of arrow A to move the front surface 10 of the plate glass 10.
By pressing B, the front surface 10A of the plate glass 10 is pressed against the first positioning member 18. In addition, the first pressing member 12 presses the front surface 10A of the plate glass 10 against the first positioning member and the second pressing member 20,
20 in the direction of arrow B, and the side surface 10C of the plate glass 10 is moved.
Press. As a result, the side surface 10D of the plate glass 10 is pressed by the second positioning members 22, 22, and the plate glass 10 is positioned at the cutting position. Therefore, the plate glass 10 slides on the conveying path and automatically moves to the cutting table 16, so that the productivity is improved.

Since the long actuators 26, 26 for moving in the B direction are required, there is a problem that equipment cost increases.

要があるという問題がある。In the conventional method of positioning the plate glass 10 by abutting it on the first and second positioning members,
Since the first and second positioning members wear while coming into contact with the edge of the plate glass 10, the positioning accuracy of the plate glass 10 gradually decreases. As a result, an error occurs in the glass product size cut out from the plate glass 10 over time. for that reason,
There is a problem that it is necessary to periodically correct the positions of the first and second positioning members.

ことができる。As described above, according to the method and apparatus for detecting the position of a plate-shaped body according to the present invention, one side of a rectangular plate-shaped body arranged on a table is brought into contact with a reference stopper by pressing means. The position of the other side orthogonal to one side of this rectangular plate is measured by the edge detecting means. In this way, since the step of positioning the rectangular plate-shaped body by the reference stopper and the pressing member can be reduced to only one side of the rectangular plate-shaped body, the number of long actuators for moving the pressing means can be reduced. it can. Further, it is not necessary to process the table with a notch for moving the pressing means. As a result, the device can be simplified, and the equipment cost can be reduced.
