[Problem] To provide a snapping device that, simultaneously with the formation of a scribe line during snapping processing, changes the rolling direction of a snapping cutter wheel to the direction in which a scribe line to be formed next is planned to extend in a peripheral edge area of a glass plate. [Solution] First and second snapping devices: cause a snapping jig to move from a scribe line formation start point 135a in the vicinity of the outer side of an outline cut line K1 toward an outer peripheral edge 56c of a glass plate 11; form a scribe line K2 extending in a predetermined direction in a scribe line-forming location of a peripheral edge area 56b of the glass plate 11; after a snapping cutter wheel has moved to a rolling direction-changing point 135c in the vicinity of the inner side of the outer peripheral edge 56c of the glass plate 11, cause the snapping jig to travel in parallel to an upper surface 12 of the peripheral edge area 56b of the glass plate 11 in a direction in which a scribe line K2 to be formed next on the upper surface 12 is planned to extend, while also causing the snapping cutter wheel, which is capable of rotating 360° around the central axis of a cutter holder in contact with the upper surface 12 of the peripheral edge area 56b of the glass 11, to rotate around the center axis of the cutter holder; and form a scribe line K2 to be formed next extending in a planned direction in the vicinity of the inner side of the outer peripheral edge 56b of the glass plate 11 while changing the rolling direction of the snapping cutter wheel to the direction in which the scribe line K2 is planned to extend.
A bend-breaking jig changes a rolling direction of a bend-breaking cutter wheel in bend-breaking processing. In first and second bend-breaking jigs, a cutter wheel axis extending in an up-down direction of the cutter wheel is eccentric radially outward with respect to a cutter holder center axis extending in an up-down direction of a bend-breaking cutter holder. The cutter wheel is rotatable by 360° in a direction around the cutter wheel axis with respect to the cutter holder. When the first and second bend-breaking jigs slightly travel on an upper surface of an edge part of a glass plate in a predetermined direction in parallel with the upper surface, the cutter wheel abutting on the upper surface of a glass plate edge part rotates in the direction around the cutter wheel axis, and a rolling direction of the cutter wheel becomes the same as a traveling direction of the bend-breaking jigs.
A bend-breaking system, after a cutter wheel forms an end cutting line at an edge portion of a glass plate, the cutter wheel is raised by a holder raising/lowering mechanism. A first pressing member is lowered by the first pressing member raising/lowering mechanism to sandwich a main body portion and the edge portion of the glass plate between the first pressing member and the first and second support members. A second support member is lowered by the second support member raising/lowering mechanism, and the second pressing member is lowered by the second pressing member raising/lowering mechanism to press the edge portion of the glass plate extending to an outer side of a contour cutting line downward while maintain the sandwiching of the main body portion and bend-breaks the edge portion. The bend-breaking system smoothly and reliably bend-breaks an edge portion of a glass plate to be processed in bend-breaking processing.
As a snapping device that, during a snapping process, can transmit snapping of a glass sheet from an external shape cutout line toward an end cutting line and can smoothly snap the entirety of a surrounding edge area outside of the external shape cutout line of the glass sheet, the present invention provides a device wherein a snapping jig is moved from an end cutting line formation starting point, which is in the vicinity of a peripheral area of the glass sheet, including a peripheral edge of the same, toward an end cutting line formation ending point, which is outside of and in the vicinity of the external shape cutout line, an end cutting line that extends from the end cutting line formation starting point toward the end cutting line formation ending point is formed in an end cutting line formation section of the surrounding edge area of the glass sheet, the end cutting line formation starting point is at the peripheral edge of the peripheral area of the glass sheet, or is a location that is removed from the peripheral edge of the peripheral area by a very short distance toward the inside, or is a location that is removed from the peripheral edge of the peripheral area by a very short distance toward the outside, and the end cutting line formation ending point is a location that is removed from the external shape cutout line by a very short distance toward the outside.
A glass plate processing system includes a first aligning means. When first and second glass plates different upper and lower surface areas are processed, the first aligning means aligns a first side edge extending in a front-rear direction on one side in a width direction of a first glass plate to be processed first with a first side edge extending in the front-rear direction on the one side in the width direction of a second glass plate to be processed later. The glass plate processing system causes the first aligning means to align the first side edge of the second glass plate at a position of the first side edge of the first glass plate to perform processing on the second glass plate. The glass plate processing system shortens a moving distance and arrival time for a processing device and shortens cycle time of processing.

[Problem] To provide a grinding system in which the main body of a glass plate can be firmly fixed and which, when the peripheral edges of the main body of the glass plate are ground by pressing the lateral surface (cylindrical portion) of the rotating grinding wheel of a grinder against the peripheral edges, can grind the peripheral edges of the main body of the glass plate while preventing the main body from sliding horizontally (shifting horizontally).

SNAPPINGLY DIVIDING SYSTEM AND SNAPPINGLY DIVIDING PROCESSING METHOD
[Problem] To provide a snappingly dividing system which can snappingly divide an edge part of a glass plate workpiece smoothly and reliably in snappingly dividing processing. [Solution] The snappingly dividing system 10a is configured such that: a snappingly dividing cutter wheel that is lowered in the vertical direction by means of a holder lifting and lowering mechanism (a first lifting and lowering mechanism) forms an end cutting line at an edge part of a glass plate; then the snappingly dividing cutter wheel is lifted by means of the holder lifting and lowering mechanism; then a first pressing member is lowered by means of a first pressing member lifting and lowering mechanism (a second lifting and lowering mechanism) so that the first pressing member and first and second supporting members sandwich a main body part and the edge part of the glass plate therebetween; subsequent to the sandwiching of the main body part and the edge part of the glass plate by the first pressing member a and the first and second supporting members, the second supporting member is lowered by means of a second supporting member lifting and lowering mechanism (a fourth lifting and lowering mechanism); and a second pressing member is lowered by means of a second pressing member lifting and lowering mechanism (a third lifting and lowering mechanism) while maintaining the sandwiching of the main body part of the glass plate by the first pressing member and the first supporting member, so that the edge part of the glass plate which extends to the outside of an outer shape cutting line is pressed in a downward direction. As a result, the edge part is snappingly divided.
[Problem] Provided are a cleaving system and a cleaving processing method which can cleave smoothly, and in an assured manner, an edge of a sheet glass to be cleaved in a cleaving process. [Solution] A cleaving system 10a operates such that: after a cleaving cutter wheel forms an edge cut line at an edge of a sheet glass, a first lifting mechanism vertically lifts the cleaving cutter wheel; after the lifting of the cleaving cutter wheel, a rotation mechanism causes the cleaving cutter wheel and first and second press members to rotate axially such that the first press member is positioned at the edge of the sheet glass extending at the outer side of the outer shape cutting line; upon positioning of the first press member at the edge of the sheet glass, a third lifting mechanism vertically lowers the second press member so that the second press member and first and second support members sandwich a body portion and the edge of the sheet glass; upon the sandwiching of the body portion and the edge by the second press member and the first and second support members, a fourth lifting mechanism vertically lowers the second support member; the second lifting mechanism vertically lowers the first press member while the body portion is kept sandwiched between the second press member and the first support member; and thereby, the edge of the sheet glass extending at the outer side of the outer shape cutting line is pressed downward, and the edge is cleaved.
[Problem] To provide a bend-breaking jig that, in a bend-breaking process, makes it possible to easily change the rolling direction of a bend-breaking cutter wheel to the direction in which an imaginary scribe line of an edge part of a glass plate extends, without the use of a θ axis servo motor or transmission member (pulley, belt, etc.). [Solution] In first and second bend-breaking jigs 83a, 83b, a cutter wheel axis O3 extending in the vertical direction of a bend-breaking cutter wheel 92 is eccentric in a radially outward direction with respect to a cutter holder center axis O2 extending in the vertical direction of a bend-breaking cutter holder 91, and the bend-breaking cutter wheel 92 is rotatable 360° about the cutter wheel axis O3 with respect to the bend-breaking cutter holder 91. The first and second bend-breaking jigs 83a, 83b, by travelling slightly in a prescribed direction on the upper surface of an edge part of a glass plate and in parallel with the upper surface, cause the bend-breaking cutter wheel 92 which contacts the upper surface of the edge part of the glass plate to rotate about the cutter wheel axis O3, such that the rolling direction of the bend-breaking cutter wheel 92 is the same as the travelling direction of the bend-breaking jigs 83a, 83b.
[Problem] To provide a cutting jig which can easily change, during a cutting process, the rolling direction of a cutting cutter wheel to a direction in which a virtual end cut line at an edge portion of a glass plate extends, without using a θ-axis servo motor or a transmission member (such as a pulley and a belt). [Solution] In each of a first and a second cutting jigs (cutting jig) according to the present invention, a vertically extending cutter wheel axis of a cutting cutter wheel decenters radially outward relative to a vertically extending cutter holder center axis of a cutting cutter holder, and the cutting cutter wheel is rotatable 360° around the cutter wheel axis with respect to the cutting cutter holder. Each of the first and second cutting jigs (cutting jig) slightly travels on the upper surface, at an edge portion, of a glass plate in parallel thereto and in a prescribed direction, whereby the cutting cutter wheel being in contact with the upper surface, at the edge portion, of the glass plate rotates around the cutter wheel axis, and the rolling direction of the cutting cutter wheel coincides with the travelling direction of the cutting jig.

In the glass plate machining system 10, the first matching means matches the side edge, extending in the front-back direction with respect to one width direction of the glass plate that has a surface area and is to be subsequently machined, with the position of the side edge extending in the front-back direction with respect to one width direction of the glass plate to be machined first, and the glass plate that has the different area and is to be subsequently machined is machined.
