(57) [Summary] [Purpose] Make a constant depth of cut into the glass sheet. [Structure] An end of an arm 10 is rotatably supported by a lifting / lowering body 6 in a plate glass cutting device, a cutter 5 is held at the tip of this arm, and a downward pressing force of an auxiliary cylinder 13 attached to the lifting / lowering body. Is applied to the upper surface of the tip of the arm to make the depth of cut constant.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate glass cutting device.

[0002]

[Prior art]

 In a conventional sheet glass cutting device, as shown in Japanese Utility Model Laid-Open No. 11034/1990, when a bar material is run along the surface of a plate glass placed on a table, the slider for the bar material is run before the bar material runs. Since the cutter provided on the lower part is lowered by the extension action of the cylinder, a cutting line (cut) is made in the plate glass.

[0003]

[Problems to be solved by the device]

 According to the above configuration, the cutter is first brought into contact with the surface of the plate glass while the elevating body is lowered by the extension action of one cylinder, and then the set pressure of the cylinder is applied to the cutter contacted with the plate glass. As a result, a downward pressure is applied to insert the cutting line, so the depth of cut in the plate glass is shallow from the time the cutter contacts the plate glass until the set pressure of the cylinder acts on the cutter, and then becomes deeper.

[0006] Therefore, a shallow cut having a certain length causes inconvenience when the plate glass is cut.

Therefore, an object of the present invention is to provide a plate glass cutting device in which a cutter is brought into contact with a plate glass and a set pressure is applied to the cutter at the same time.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a table on which a plate glass is placed, a traveling body provided so as to reciprocate along the surface of the plate glass placed on the table, and a cylinder on the traveling body. In the plate glass cutting device in which the cutter is moved up and down together with the lifting body, the end of the arm is rotatably supported by the lifting body and the cutter is held at the tip of the arm. In addition, a structure is adopted in which an auxiliary cylinder for exerting downward pressure is provided at the tip of the arm.

[0007]

[Action]

 After the plate glass is placed on the table, the traveling body travels in one direction, and the lifting and lowering body is lowered by the action of the cylinder to bring the cutter into contact with the surface of the plate glass. By the action, the tip of the arm is pushed down and the optimum pressing force is applied to the incision, so that the incision (cutting line) of a certain depth is made from the moment the cutter contacts the plate glass.

【Example】

 Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings.

A shown in FIG. 1 is a plate glass a cutting device.

The cutting device A for the plate glass a has a table 1 on which the plate glass a is placed, a rail 2 laid outside the opposite edge of the table 1, and a rolling ball at both ends built in the rail. A horizontal traveling body 3 with a reciprocating traveling function that allows a smooth traveling by fitting a sliding member (not shown), and an elevating body with a cutter 5 that is elevated by the action of a cylinder 4 provided on the traveling body 3. 6 and 6.

The traveling body 3 and the first traveling body that can reciprocate in the X-axis direction as shown in FIG. 1 and the first traveling body that can reciprocate in the Y-axis direction perpendicular to the X-axis direction. In addition to the combination with the second traveling body attached to the traveling body, one traveling body may be provided so as to be reciprocable. The reciprocating motion of the traveling body 3 employs a male screw driven by the operation of a reversible motor and a female screw screwed into the male screw.

In addition, a plurality of sliders 8 that run using the rails 7 provided along the longitudinal direction of the traveling body 3 as guides are arranged on the traveling body 3, and each of the sliders 8 has an elevating body with a cutter 5. 6 is provided, and the slider 8 is moved so that the cutter 5 is aligned with the cutting line, and then the slider 8 is stopped from sliding with respect to the rail 7 via a brake device (not shown) by the action of a solenoid. .

Further, as shown in FIGS. 2 and 3, the cutter 5 rotatably supports the end of the arm 10 on each lifting body 6 via a horizontal pin 9 and stops it at the tip of the arm 10. A holder 12 of the cutter 5 is attached via a screw 11, and an auxiliary cylinder 13 attached to the lifting / lowering body 6 exerts a downward pressing force suitable for cutting on the upper end surface of the arm 10.

The arm 10 includes a screw 15 that can be vertically moved by screwing on an upper protrusion 14 protruding from the arm 10, and an elevating body so that a lower end of the screw 15 is brought into contact with an upper surface thereof. The tip of the arm 10 is prevented from descending from a fixed position composed of the lower projecting piece 16 protruding from 6.

Reference numeral 17 in the figure denotes a lowering stop positioning device for the lifting body 6.

With the above configuration, the plate glass a is placed on the table 1 and then the traveling body 3 travels in one direction.

At this time, since the lifting / lowering body 6 is lowered by the action of the cylinder 4, the cutter 5 is brought into contact with the surface of the plate glass a, and the tip of the arm 10 is attached to the abutted cutter 5 by the action of the auxiliary cylinder 13. Since it is pressed down, the optimum pressing force for cutting acts almost simultaneously with the contact.

Therefore, a cut having a constant depth is made in the glass sheet a from the start to the end of the cut.

[0019]

【effect】

 As described above, in the plate glass cutting device according to the present invention, since the downward pressing force optimum for cutting is applied to the cutter by the auxiliary cylinder, from the time when the cutter is brought into contact with the plate glass to the end. Up to a certain depth of incision can be made.

Therefore, it is possible to eliminate the inconvenience at the time of cutting that is caused by the shallow cutting depth.
