2. Description of the Related Art Conventionally, in the case of cutting a thread surface or a square surface of a glass plate of furniture or the like having a large thickness and a large width, the glass plate is transported while being held between timing belts of upper and lower conveyors. Then, cutting and grinding were performed with a rotary grindstone from both sides.

[0003] However, recent glass plate processing has been used for electronic equipment and the like in a length of 25 mm, a width of 9 mm, and a thickness of 1.1 to 1.1 mm.
Highly accurate processing of extremely thin and short pieces of about 6.0 mm is required.

However, the vibration between the upper teeth of the timing belt and the pressing roller, which moves when the ultra-thin and short glass plates are conveyed while being held between the timing belts of the upper and lower conveyors, the pressing points of the pressing roller, and the like. Between the pressing points, the clamping pressure of the glass plate is raised and lowered, the ultra-short and small glass plate is damaged in the high pressure part, the vertical and horizontal displacement of the sandwiched glass plate is generated in the low pressure part, and the next cutting or grinding is meandering. There was a problem that it could not withstand processing.

[0005]

An upper holding synthetic resin guide 6 is slidably contacted with the upper teeth 2 "of the lower transition portion 2 'of the upper conveyor 2, and a relatively thick metal made of stainless steel is provided on the upper surface of the synthetic resin guide 6. The plate 7 is integrally layered with a bolt, an adhesive or the like, and the side guides 6 'of the lower transition portion 2' are vertically provided on both sides of the synthetic resin guide 6 at regular intervals.

A plurality of bearing projections 1 are provided on the upper surface of the metal plate 7.
0, 10 are provided, and upward grooved metal fittings 12, 12, 12 are provided at equally divided positions between the projections 10, 10, and the bending portion 8c of the main bending rod 8 is pivotally mounted at a plurality of positions of the machine frame 5 by a pivot 9 '. It is pivotally supported, and the lower end 8b of the operating rod 8 is supported on the bearing projection 10 by a supporting shaft 8 ". A plurality of sub-shapes having the same shape as the main bending operating rod 8 are provided at equally divided positions between the operating shafts 9 ', 9'. Bending Kong 8 ',
8 ′, 8 ′ bent portion 8c is pivotally supported 9 by a pivot 9 ′,
An engagement fitting 11 pivotally supported on the lower end 8b of the auxiliary bending operation rod 8 'is fitted into the upward groove fitting 12.

[0010] The main and sub bending arms 8, 8 'thus constructed

Not only is the gripper securely clamped between the lower transition portion and the clamping pressure is equally appropriate, but also the inclination processing direction (arrow b direction) of the lower end portion of the primary and secondary bending levers is the transition direction of the upper and lower transition portions (arrow direction). a), the lower end of the bending rod rotates counter to the inclined pressing direction (direction of arrow b) about the pivot axis even if the transition-side tip of the glass plate faces the direction of arrow b. The glass sheet moves to the side opposite to the inclined pressing direction, so that the resistance at the transition side end of the glass sheet is reduced, and the supplied glass sheet easily enters between the upper and lower transition parts. .

In addition, the upper and lower transition portions can be improved in both-side grinding accuracy of the sandwiched glass plate without a possibility of meandering.
