Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cutter width adjustment device in a cutting machine for sheet glass.

[Conventional technology]

As shown in FIG.
A required number of fitting parts 4 for the mounting fittings are provided by two notches 3 which are formed by making two cuts from one side edge of the glass plate 1 to reach the through hole 2 with a width smaller than the diameter of the glass plate 1.

As shown in FIG. 4, the cutter provided with the notch 3 is made by first fitting one side collar 6 onto the drive shaft 5 and fixing the side collar 6 to the drive shaft 5 by tightening bolts. Next, the cutter 7, the center collar 8, the cutter 9, and the remaining side collar 10 are fitted in order, and then the cutter 7, the center collar 8, and the remaining side collar 6 are fitted.
While pressing the cutter 9, the side collar is fixed to the drive shaft by tightening the bolt.

At this time, the spacing between the cutters 7 and 9 and the width of the notch 3 are made to match by the center collar 8.

[Problem that the invention attempts to solve]

When changing the width of the notch, a center collar with a width equal to the opposing spacing of the cutters is selected and used, so many center collars with different widths are required, and when replacing the center collar, disassembly and assembly are required. Since it is necessary, there was a problem that required a lot of effort.

[Means for solving problems]

In order to solve the above problems, this invention has a cylinder fitted on the outside of the drive shaft that freely rotates in a fixed position as it is operated, and a threaded part facing in the opposite direction from the center of the outer circumference of the cylinder to both ends. Further, the opposing ends are slidably fitted and engaged so as to rotate together, and a pair of cylindrical bodies are screwed into both of the threaded parts, and one of the cylindrical bodies and the drive shaft is connected to the above-mentioned cylindrical body. A transmission part is provided that transmits rotation from the drive shaft to the cylindrical body without obstructing the sliding of the cylindrical body, and two cutters are fixed in parallel to both cylindrical bodies, and a cutter remains in the threaded part. It is constructed by screwing in a nut that fixes one cylindrical body to the cylindrical body.

[Effect]

To adjust the width of the cutter, first loosen the nut, then rotate the cylindrical body, and slide both cylindrical bodies toward or away from each other using the threaded part of the cylindrical body. Adjust the width between the sliding cutters to the specified width.

After that, tighten the nut to fix the cylindrical body on the nut side to the cylindrical body.

〔Example〕

In the figure, A is a cutting machine for sheet glass.

As shown in FIG. 1, the above cutting machine A includes a pedestal 12 that slides forward and backward by the expansion and contraction action of a cylinder 11, and a pedestal 12 that is placed on the pedestal 12 while moving the pedestal 12 forward. It is composed of a pair of rotary cutters 13 and 14 that make two cuts from the edge of the glass plate into a fitting part provided in front of the glass plate.

The cutters 13 and 14 are installed on a movable body 16 that slides in the left-right direction using a rail 15 as a guide so as to be driven by a motor (not shown), and are attached to the movable body 16 by a male thread 17 with a handle. By screwing in a certain female screw 18 and rotating the male screw 17, the movable body 1
Slide cutter 1 into place while sliding cutter 6.
3 and 14 are stopped.

Further, a cylindrical body 21 is fitted into the drive shaft 19 of the cutters 13, 14, and is freely rotated in a fixed position by operating a camera 20 provided at the end.

The rotation of the cylindrical body 21 in a fixed position is performed by bringing the tip of the cylindrical body 21 into contact with the stepped portion 22 of the drive shaft 19, and then rotating the cylindrical body 21 so that it contacts the plate surface of the camera 20. This is done by fitting an E-ring 23 into the annular groove.

In addition, threaded portions 24 and 25 are provided in opposite directions from the center of the outer periphery of the cylinder 21 to both ends, and the opposing ends are slidably fitted into the threaded portions 24 and 25 and engaged to rotate together. Screw holes 28 and 29 provided in the end walls of the small-diameter cylindrical body 26 and the large-diameter cylindrical body 27 are screwed into them.

In the illustrated case, the engaging portion 33 is formed by a key and a keyway, but other methods may be used for the above-mentioned engagement.

Furthermore, two parallel cutters 13 and 14 are attached to both cylindrical bodies 26 and 27.

The cutters 13 and 14 described above are fixed by screws 30.

Further, the threaded portion 24 includes a cylindrical body 26 on the cylindrical body 21.
A nut 31 for fixing is screwed in.

Furthermore, the drive shaft 19 and the cylindrical body 27 include
A transmission section 32 that transmits rotation from the drive shaft 19 to the cylindrical body 27 is provided.

The above-mentioned transmission section 32 is configured to include a key and a keyway in the illustrated case.

The cutting machine according to this invention has the above configuration, and when the drive shaft 19 is driven by the motor, rotation is transmitted to the cylindrical body 27 by the transmission part 32, and the engagement part 33 is transferred from the cylindrical body 27. Since both the cylindrical bodies 26 are rotated, both the cylindrical bodies 2
The cutters 14 and 13 rotate together with the cutters 7 and 26.

When the plate glass 1 is placed on the pedestal 12 and the pedestal 12 is moved forward by the contraction action of the cylinder 11, the pedestal 12 is moved forward from the edge of the plate glass 1 to near the edge of the plate glass 1. Fitting part 4
Cutouts 3 are formed by making two cuts with cutters 13 and 14.

Next, when adjusting the width of the cutters 13 and 14,
First, after loosening the nut 31, rotate the cylinder 21 using the camera 20, and rotate the threaded part 2 of the cylinder 21.
4, 25 and screw holes 28, 29 to synchronize both cylindrical bodies 26, 27 with each other and slide them in the approaching direction or in the separating direction, while predetermining the width between the two cutters 13, 14 that slide together. Adjust so that the width is .

Thereafter, the nut 31 is tightened to fix the cylindrical body 26 to the cylindrical body 21.

〔effect〕

As described above, according to the cutter width adjustment device according to this invention, the left and right cylindrical bodies screwed into both threaded portions of the cylindrical body are synchronized while rotating the cylindrical body, and the left and right cylindrical bodies are moved in the approaching direction or toward each other. Since the width of the cutter attached to both the cylindrical bodies is adjusted by sliding in the direction of separation, the width of the cutter can be adjusted extremely easily and quickly.

In particular, after aligning the bisecting position between the cutters with the cut reference line, even if you adjust the width of the cutter while sliding the cutters in sync, the cut line made by the cutter will match the defined line. can be done.
