Embodiment Construction

[0027] Hereinafter, typical embodiments of the present invention will be described with reference to the drawings.

[0028] like figure 2 As shown, in order to cut off the glass plate G conveyed in a wide band shape with a predetermined size, by pressing the wheel-shaped cutter head 29 of the cutter against the surface of the glass plate, the upper side surface of the glass plate is preliminarily cut. The conveying direction (longitudinal line 7) and the width direction (cross line 7') of the glass plate are given groove-shaped line 7 (refer to image 3 ). Thus, the glass sheet is separated by breaking along the widthwise scribe line 7 ′ by the break roller 40 provided on the downstream side, and is separated along the longitudinal scribe line 7 in a subsequent process not shown. break to separate. As a result, a glass plate of the target size can be obtained.

[0029] like figure 1 As shown, in a typical embodiment of the present invention, such as figure 2 As shown, ...

Abstract

The invention provides a cutting line on glass sheet providing apparatus. A device for scoring a glass sheet applies a score line for cutting to the glass sheet conveyed on conveyance rollers. The device has a cutter for applying a score line to a glass sheet, ball slide means capable of lifting and lowering the cutter while following vertical movement of the glass sheet conveyed and, when the cutter is pressed against the surface of the glass sheet, maintaining pressing force constant by absorbing excessive pressing force, a spring for applying appropriate cutter pressure to the surface of the glass sheet, and pressing means for pressing an arm to a position on the surface of the glass sheet, the arm supporting the ball slide means, the spring, and the cutter.

Description

technical field [0001] The present invention relates to a device for imparting kerf lines to glass sheets. The device is used for adding kerf lines to form and transport wide-width glass ribbons, especially thin-plate glass of 2 mm or less, in a predetermined size. By cutting, a uniform cut line is given without damaging the glass plate. Background technique [0002] The glass ribbon formed by the float method is transferred on the transfer rollers in the annealing process and the inspection process, and the required size positions in the vertical and horizontal directions are given notch lines, and the glass ribbon is broken by breaking, and the plate is harvested. However, the glass ribbon may be conveyed in a so-called undulating state that zigzags in the width direction and waves up and down due to various factors received during the conveyance process. [0003] In recent years, as a glass plate for display, a thin plate of 2 mm or less is required. In particular, sinc...
