[0087] like figure 1 as well as figure 2 As shown, the glass sheet manufacturing apparatus 1 according to the first embodiment of the present invention cuts a flexible glass ribbon G (for example, with a thickness of 700 μm or less) at predetermined lengths that is continuously formed by the down-draw method and conveyed downward. From this glass ribbon G, the glass plate Gx which is a cut-out part is cut out continuously by this. The manufacturing apparatus 1 of a glass plate is comprised so that the formation of the scribe line S to the surface Ga of the glass ribbon G (front and back Ga of the glass ribbon G, surface Ga of Gb) along the width direction (X-X direction), and performing repeatedly The breaking and cutting of the glass ribbon G performed by applying a bending stress to the scribe line forming part Gs in which the scribe line S was formed. It should be noted that, in figure 1 as well as figure 2 In , the illustration of some constituent elements of the man...

[0156] The glass plate manufacturing apparatus 1 according to the second embodiment of the present invention is mainly different from the glass plate manufacturing apparatus 1 according to the above-mentioned first embodiment in that the rotation of the arm body 20ba can be changed to The position of the axis 29 of the rotation center of the arm main body 20ba; the rotating arm main body 20ba can also rotate itself. In addition, also in this 2nd Embodiment, the rod body 40 and the lower end receiving rod 39 may be arrange|positioned similarly to 1st Embodiment.

[0157] like Figure 16 As shown, the glass sheet manufacturing apparatus 1 is provided with: a rotation mechanism 48 for rotating the arm body 20ba around a central axis 47 extending along the width direction of the glass ribbon G (X-X direction); and a moving mechanism 49 for rotating the arm body 20ba. By moving while supporting the rotating mechanism 48, the arm main body 20ba connected to the rotating mechanism 4...

Abstract

A manufacturing device (1) of a glass plate is provided with a scribing mechanism (2) for forming a scribe along the width direction on a surface (Ga) of a glass ribbon (G) which is continuously formed by a down-draw method and conveyed downward. line (S), wherein the glass sheet manufacturing apparatus (1) is provided with a deformation applying mechanism (4) that makes the glass ribbon (G) to be carried into the marking mechanism (2) along the width direction Curved so that the surface (Ga) side is convex. Thereby, the glass ribbon (G) can be carried in to the scribing mechanism (2) in the state maintained in the shape suitable for forming a scribing line (S).

Description

technical field [0001] The present invention relates to a glass sheet manufacturing apparatus that forms a score line on a glass ribbon continuously formed by a down-draw method, and breaks and cuts the glass ribbon by applying bending stress to the portion where the score line is formed . Background technique [0002] As is well known, glass plates are used as glass substrates for flat panel displays such as liquid crystal displays, plasma displays, organic EL displays, and field emission displays, and are assembled in various forms such as cover glasses for smartphones and tablet PCs. electronic equipment. [0003] As one of the manufacturing methods of the glass plate, the method of cutting the glass ribbon continuously formed by the down-draw method typified by the overflow down-draw method, the slot down-draw method, the re-draw method, etc. at predetermined lengths, A glass plate is thus cut out. Also, Patent Document 1 discloses an example of an apparatus used in s...
