Abstract

PURPOSE:The movement range of the Y-rail and the Y-cursor is set with a positioning means and the blade angle of the cutter is allowed to coincide with the movement direction whereby a glass plate is efficiently cut into desired forms. CONSTITUTION:X-cursors 8, 10 are fixed to or released from X-rails 4, 6 by operating brake levers 130, 132, while Y-cursor 18 is fixed to or released from Y-rail 12 by operating brake lever 134. At this time, the movement end of the Y-rail 12 and the movement end or movement range of the Y-cursor 18 are set with index heads 80, 82. The cutting direction of the cutter 60 on the Y-cursor 18 is determined by the blade angle-changing mechanism which is composed of rotatable disk 32, index scale 40 and other parts. When cutter 60 is pressed onto the glass plate on its top, the Y-rail 12 coincides with the cutter 60 in their movement direction and the glass plate is cut.

Crimp and fix to the X rail 6. Next, the pin 106 is pushed up to release the engagement between the stopper shaft 104 and the index recess 92. In this case, by applying a strong pressing force to the Y rail 12 in the +X direction, the tip of the stopper shaft 1O-4 may be raised against the elasticity of the spring 110, and removed from the index recess 92. ! 82 is also fixed to the X rail 6 by the same method as above.

Set the moving end of the Y rail 12 in the +X direction.

The moving end or moving range of the Y cursor 14 in the 10-Y direction along the Y rail 12 can also be set by the same operation as described above. The Y rail 12 is manually moved along the X rails 4 and 6 by the operator, and the stopper device l! 84 reaches the index device v180, the stopper shaft 104 rides on the index recess forming surface of the index plate 90 and fits into the recess 92.

To cut the glass plate positioned on the mounting plate 2, the nut 36 is rotated to raise the nut 36 relative to the tubular member 34.

The lifting plate 22 is lowered by the weight applied thereto, and the tip of the cutter 60 is pressed against the glass plate. X the glass plate
When you want to cut in the direction, swing the lever 50 to release the engagement between the claw part 46a and the index recess 42, rotate the one-rotator 32 relative to the lifting plate 22, and move the claw part 46a to the index plate. 40 into the index recess 44. Thereby, the side surface of the cutter 60 becomes parallel to the X direction, and the cutting direction of the cutter 60 matches the moving direction of the cutter 60. When it is desired to cut a glass plate in the Y direction, as shown in FIG. 5, the index claw 46a is fitted into the index recess 42, and the side surface of the cutter 60 is set parallel to the Y direction. Cutter 60.

Own weight and the weight applied thereto, and X or Y of the cutter 60
Cutting the glass plate by interaction with the directional movement movement. When the cutter 60 is slightly removed from the glass plate, the cutter 60 cuts the rollers 74 or 76 on the glass plate.
The cutter 60 is supported by the cutter 60 to maintain an appropriate height position between the cutter 60 and the glass plate, thereby allowing the cutter 60 to be smoothly transferred from the edge of the glass plate onto the glass.

In this embodiment, a stopper shaft biased by a spring and an index plate are used as the x and y direction positioning means. Any device that locks movement along the rail 12 and whose locking position can be adjusted may be used, and a simple abutment member or the like may be used.
