Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scrap collecting device for a plate glass hole punching machine. More specifically, the lower half of the plate glass is cut by rotating the lower core drill upward and then the upper half of the plate glass is cut and penetrated by rotating downward. The present invention relates to a punched-dust collecting device for a plate glass hole puncher, which is adapted to collect short cylindrical punched scraps in the punching machine.

[Prior art]

 2. Description of the Related Art Conventionally, in various kinds of plate glass such as automobile window glass and display glass case, a hole having a predetermined diameter is opened at a predetermined position and a part or a device is attached to the plate glass as needed.

As a conventional plate glass drilling machine, a plate glass drilling machine of the type described below with reference to FIG. 1 is generally widely used because it hardly causes cracks or crevices at the open ends of the holes drilled. Has been prized.

First, as shown in FIG. 1A, the lower core drill 11 in which the lower shaft is raised and is rotated and raised is cut into a cylindrical hole 23 by cutting about half of the glass thickness, that is, the lower half at the hole H of the plate glass 4. To drill. Then, as shown in FIG. 1B, the lower shaft descends and the lower core drill 11 descends, and at the same time, the upper shaft simultaneously descends and the upper core drill 10 rotates and descends to cut and penetrate the upper half. Then, as shown in FIG. 1C, the scrap 20 is dropped downward.

[0005]

[Problems to be solved by the device]

 Therefore, when the upper core drill of the upper shaft cuts and penetrates the sheet glass, the scraps fall and collide with the lower core drill of the lower shaft rotating at high speed. When a collision occurs, the centrifugal force of the lower core drill causes the scraps to be blown off and scattered around, damaging the plate glass, etc., and causing various adverse effects such as damaging the work environment, and the collision causes the diamond abrasive grain surface of the core drill. There was a problem that scratches, chips, etc. occurred on the surface and the cutting ability deteriorated significantly.

[0006]

[Means for Solving the Problems]

 This invention was made in order to solve the above-mentioned problems, and the gist thereof is to rotate vertically and vertically ascend and descend along the vertical axis at the hole of the plate glass clamped horizontally to the frame. In a plate glass hole drilling machine equipped with upper and lower drill units equipped with corresponding upper and lower core drills, the shooter moves to a retracted position near the bottom of the drilled hole and moves directly below the drilled hole. And a means for retrieving the scraps received immediately below the punching place into the tray by retracting and moving the shooter. Is.

Next, the present invention will be described in detail with reference to the drawings with reference to the following embodiments.

[0008]

【Example】

 In FIG. 2, reference numeral 4 designates a plate glass horizontally clamped and fixed on the table 2 of the frame 1 by the clamp plate 3 of the slide bearing clamp unit 5. The slide bearings are provided on the vertical axis P at the hole H of the plate glass 4 above and below the vertical axis P so as to rotate and move up and down, the lower shafts 8 and 9 tips, and the lower core drills 10 and 11, respectively. The upper and lower drill units 6 and 7 are vertically fixed to the frame 1, respectively, and the lower core drill 11 is lifted to cut the lower half of the plate glass 4, and then the upper core drill 10 is lowered to move the upper half. A plate glass hole punching machine is constructed so that it can be cut through and drilled. In the upper drill unit 6, shaft lifting is air (built-in air cylinder), shaft rotation is electric (motor), and in the lower drill unit 7, shaft lifting is air (built-in cylinder), shaft rotation is air (air motor). (Because the lower shaft is splashed with water, an air motor is often used.) Each is designed to be operated. Further, 21 is a water tank, and 22 is a pump.

Reference numeral 12 denotes a supporting plate provided on the frame 1 in a portion for holding the lower drill unit 7, and an operating cylinder is provided on an upper portion of the supporting plate 12 at a position below the plate glass 4 to the left of the hole H. 13 is provided with a tip end pivotally supported by a pivot 14 so as to be swingable. A guide 18 formed of, for example, a trochanter or a support shaft is provided at a position slightly right of the pivot 14, and a wire net tray 19 is provided at the lower left of the guide 18. Further, a trough-shaped shooter 16 whose bottom is always supported by the guide 18 is pivotally connected to the tip end of the piston rod 15 of the operation cylinder 13 by a pivot pin 17. Has been done. Further, the operation cylinder 13 is connected and connected to a fluid pressure unit such as an air via a switching valve or the like. Then, by operating the operation cylinder 13, the shooter 16 repeats the retreat movement to the retreat point R position near the bottom of the perforation point H shown in FIGS. 3 and 5 and the movement immediately below the perforation point H shown in FIG. The scrap 20 (FIG. 4) received immediately below the hole H can be collected in the tray 19 by the retracting movement of the shooter 16 (FIG. 5).

[0010]

[Description of action]

 As shown in FIG. 3, the lower core drill 11 finishes the lower half cutting (piercing the cylindrical hole 23) of the plate glass 4 and descends, and at the same time, the operation cylinder 13 is operated to slide the shooter 16 in the direction of the arrow, as shown in FIG. Stand by just under the hole H. Then, as shown in FIG. 4, after the upper core drill 10 cuts and penetrates the upper half of the plate glass 4, the shooter 16 receives the punched dust 20 that has fallen as shown by the arrow. Then, as the upper core drill 10 rises, the operation cylinder 13 is operated to move the shooter 16 in the direction of the arrow shown in FIG. 5 so that the shooter 16 is inclined as shown in FIG. The reference numeral 20 automatically slides down and surely drops and collects into the lower tray 19.

[0011]

[Effect of device]

 The devised device is as described above, and the scraps that fall when the upper core drill cuts and penetrates the plate glass are caught by the shooter waiting immediately below the hole, and then the shooter is retracted by the retracting movement of the shooter. Inclination and scraps are collected in the tray, and the scraps are always reliably and automatically collected in the lower tray. Then, since the falling scraps do not collide with the lower core drill of the lower shaft that rotates at high speed, various adverse effects caused by the scraps that are blown away by the collision and the diamond abrasive grain surface of the core drill due to the collision It has an excellent effect of eliminating damage and deterioration of cutting ability.
