[Problem to be solved by the invention] However, in such conventional breaking and breaking methods, fine glass chips are generated during bending and fracture, and the generated fine glass chips scatter, and the scattered fine glass chips adhere to On the surface of the brittle material board, the attached fine glass chips may cause defects in subsequent steps. The present invention was made in view of these viewpoints, and its object is to provide a method for breaking and breaking fine pieces of glass chips that are scattered on the glass surface and adhered to the glass plate during breaking after scribing, and Break off the breaking device. [Technical Means to Solve the Problem] The breaking and breaking method of the present invention sprays the mist (fine droplets) generated by the ultrasonic generator to the cutting line area of the brittle material plate, and blows the mist to the cutting line area while performing The brittle material board is broken at the cutting line. In addition, the breaking and breaking method of the present invention sprays the mist (fine droplets) generated by the ultrasonic generator and blows it to the cutting line area of the fragile material plate, and performs the fragile material plate while sucking and recovering the blown mist. Break off at the cutting line. The breaking and breaking device of the present invention is provided with: a spray outlet that sprays and blows the mist (fine droplets) generated by the ultrasonic wave generator to the cut line area of the brittle material plate that is scheduled to be broken and broken; the spray suction port, which Suction and recover the mist that is sprayed and blown onto the cutting line area. [Effects of the Invention] According to the present invention, since the sprayed spray generated by the ultrasonic generating device makes the area of the cutting line scheduled to be broken and divided into a wet state and covered, it is prevented from breaking and breaking the fine glass sheet The chips are scattered, and the fine glass chips produced are recovered together with the mist, so it can prevent adhesion to the surface of the brittle material board.

In FIGS. 1 and 2, a breaking and breaking device 1 according to an embodiment of the present invention is provided with a conveyor belt device 4 which horizontally supports a glass plate 3 as a brittle material plate with a cutting line 2 formed on the upper surface, and It is conveyed linearly along the conveying direction A; the breaking device 5 is arranged parallel to the conveying direction A of the glass plate 3. In this example, the cutting line 2 linearly extends from one edge of the glass plate 3 in the conveying direction A to the other edge of the glass plate 3 in the conveying direction A to be formed on the upper surface of the glass plate 3. The conveyor belt device 4 that horizontally supports the glass plate 3 and linearly conveys it in the conveying direction A is provided with a plurality of endless belts 6, which horizontally support the glass plate 3, and convey the glass plate in a straight line in the conveying direction A by winding 3; The driving device 7 makes the endless belt 6 circulate; and each endless belt 6 is horizontally erected and supported on each of the plurality of supports 8 in a freely circling manner. The breaking device 5 arranged along the conveyor belt device 4 in one side area 9 of the conveyor belt device 4 is provided with a support rod 10 which supports from below an edge of the glass plate 3 in the conveying direction A to the glass plate 3 in the conveying direction A The cutting line 2 of the glass plate 3 on the other edge; the spray device 11, which is above the support rod 10, is arranged parallel to the support rod 10; the spray suction device 12, which is adjacent to the spray device 11 and parallel to the spray The device 11 is set; the break-off rod 14 is set parallel to the support rod 10, and in the outer region 13 of the support rod 10, relative to the support rod 10 and the glass plate 3, it is set in the upper area. The spray device 11 is provided with a spray outlet body 16 which provides a spray outlet 15 for spraying mist (fine droplets) downward at the lower end; and a plurality of ultrasonic mist generating devices 17 connected to the mist spray outlet body 16. The spray device 11 is installed in the erection frame 31 via the bracket 32 in the mist spray outlet body 16. The spray outlet 15 which is arranged at the necessary height position above the glass plate 3 and opens over the entire length of the cutting line 2 in the conveying direction A is opened toward and along the support rod 10. The spray suction device 12 is provided with: a mist suction mouth body 19 with a spray suction port 18 opening at the lower end over the entire length of the cutting line 2 in the conveying direction A; and a dust collecting device 21 connected to a plurality of ducts 20 The mist suction port body 19; and the mist suction port 18 and the mist ejection port 15 are parallel and juxtaposed. In addition, the spray suction port 18 also faces the upper surface of the glass plate 3 and opens over the entire length of the support rod 10, in other words, opens over the entire length of the cutting line 2. The spray suction device 12 is installed in the erection frame 31 through the bracket 32 in the mist suction mouth 19. The support rod 10 is installed on the base frame 23 via the lifting device 22, and the lifting device 22 performs the lifting action. If the conveyed glass plate 3 reaches the breaking area, it is positioned and stopped, and the supporting rod 10 rises by the action of the lifting device 22, and supports the position of the cutting line 2 of the glass plate 3 scheduled to be broken from below. In addition, the breaking rod 14 is also installed on the frame 25 erected above the conveyor belt device 4 via the lifting device 24, and the lifting device 24 performs the lifting action. If the conveyed glass plate 3 reaches the breaking area, is positioned and stopped, the breaking rod 14 is lowered by the action of the lifting device 24, and the glass plate 3 is pressed downward due to the lowering, and the support rod 10 is used as a fulcrum to press and fold Bending the glass plate 3 causes the glass plate 3 to be broken from the cutting line 2. Below the breaking device 5, an oblique receiving table 28 is provided, which receives the broken glass scraps 26 and guides the glass scraps 26 to slide down obliquely; a collecting box 27 receives the glass scraps 26 of the oblique receiving table 28. In the breaking and breaking device 1, a glass plate 3 with a predetermined cutting line 2 for breaking and breaking is formed on the upper surface in advance, so that the cutting line 2 is located on the side area of the conveyor belt device 4 and is parallel to the conveying direction A and aligned The posture of the supporting rod 10 of the quasi-breaking device 5 is carried into the conveyor belt device 4, and the glass plate 3 in this posture is conveyed in the conveying direction by the action of the conveyor belt device 4. After conveying, the glass plate 3 is positioned in the area of the breaking device 5 And stop. When the glass plate 3 is positioned and stopped, the supporting rod 10 rises and stops. After the rising and stopping, the supporting rod 10 supports the cutting line 2 of the glass plate 3 below the cutting line 2. At the same time, the mist generated by the ultrasonic mist generating device 17 is sprayed from the upper direction to the glass plate 3 in the area of the cutting line 2 through the spray outlet 15. The glass plate 3 in the area of the cutting line 2 is wetted by spraying, and the area of the cutting line 2 is covered by the spray. In this state, the breaking rod 14 descends, and the lowered breaking rod 14 will support the lower part of the cutting line 2 The supporting rod 10 serves as a fulcrum to press and bend the glass plate 3, and break it at the cutting line 2. The fine flakes of glass flakes generated together with the glass flakes 26 generated by breaking and breaking are suppressed from scattering around by the wet film and the spray, and the fine flakes of glass flakes mixed in the spray are sucked together with the spray To the spray suction port 18, the spray suction port body 19 and the duct 20 are collected to the dust collector 21 and removed. As a result, it is possible to prevent the fine glass chips from adhering to the glass plate 3 which is the finished product after being broken.
