PLATE MATERIAL CUTTING UNIT, CUTTING DEVICE HAVING THE CUTTING UNIT, AND CUTTING FACILITY HAVING THE CUTTING DEVICE

摘要

A compact cutting apparatus capable of scribing and cutting plate materials, such as large thin glass plates, in a short amount of time without reducing the quality of the cut plate materials is provided. The cutting apparatus is equipped with a belt conveyor (2) that supports the bottom edge of a glass plate (G) in an upright state, a fluid guide (8) for applying fluid pressure on a surface of the glass plate (G) to support the glass plate (G) in a non-contact manner, and a pair of cutting units (11, 12) which are provided separated from each other in the conveyance direction of the glass plate (G). Each of the cutting units (11, 12) is equipped with a clamp (15), a scribe forming device (16), and a cutting device (17) in this order from the side thereof closest to the other plate material cutting unit (11, 12). The clamp (15) grips the glass plate from both sides. The scribe forming device (16) forms a scribe for cutting, by moving vertically along the surface of the glass plate (G) in the vicinity of the clamp (15). The cutting device is equipped with a cutting bar (25) for pressing a portion of the glass plate (G) opposite the scribe in a planar direction with respect to the portion of the glass plate (G) which is gripped by the clamp (15).
