Description

[Detailed description of the invention] This invention relates to a gasket mounting jig.

Conventionally, when attaching a replaceable gasket made of rubber or synthetic resin to the periphery of a glass plate, this was done by hand or using a simple jig, and the gasket had to be attached to a part of the corner of the glass plate. The cuts are usually made using a blade separate from the jig, such as scissors.

However, this type of method has drawbacks such as it is not easy to make gasket cuts and it is not easy to make cuts at accurate positions.

This invention solves the above-mentioned conventional difficulties, and provides a cutting blade that can automatically actuate the guide body of the jig to form a cut in the gasket when the jig comes to a part of the corner of the glass plate. It is an object of the present invention to provide a gasket mounting jig that can automate the work of making cuts in gaskets, improve work efficiency, and ensure accurate cut positions.

Further, a guide body 4 movable along the edge of the glass plate 8 is provided at the end projecting downward.

This guide body 4 is formed of wheels.

Note that the guide body 4 and the sliding part do not need to be wheels, and may be fixed bodies as long as they are made of a material with low frictional resistance.

The thus configured connecting body 3 is urged upward by a spring 22 provided on the frame body 2, as shown in FIG.

A lever 13 is provided on the upper part of the frame 2 and is pivotally supported at the rear in the moving direction of the case 2 so as to be swingable by a required angle.

This lever 13 is pushed upward by the connecting body 3 which is biased by a spring 22.

Near the upper end of the guide part γ, the frame body 2 is provided with a grip part 15 that can move forward and backward in the lateral direction, and an adjustment member 14 is formed in this part.

A protrusion 13a is provided near the base of the grip portion 13c of the lever 13.

The gripping part 15 consists of a fixed part 15a fixed to the frame 2, and a sliding part 15b fitted into the fixed part 15a and movable back and forth along the fixed part 15a. The jig 1 is biased in the moving direction by a compression spring 16 interposed between the portion 15a and the sliding portion 15b.

A long hole 17 is provided in one side of the fixed part 15a along its longitudinal direction, and the long hole 1γ is provided in the sliding part 15b.
A screw 18 is provided opposite to the screw 18 , and the tip of the screw 18 is loosely fitted into the elongated hole 17 .

The long hole 17 and the screw 18 allow the sliding part 1 to
The sliding range of 5b is regulated.

The protrusion 13a of the lever 13 is located at the required position of the sliding portion 15b.
A recess 19 into which the lever 1 can be fitted is provided.

Note that the adjustment member 14 does not need to be provided at the grip, and may be provided at any location on the frame 2 as long as it regulates the swinging range of the lever and can make the swinging range variable. It doesn't have to be from .

In addition, 20 in the figure is a lip portion 6a formed by the guide portion 7, the presser roller, and the auxiliary plate 10.10.

This is a correction roller for bringing the gasket 6 with the widened gap 6a into close contact with the glass plate 8.

In such a configuration, when installing the gasket 6, first attach the gasket 6 to the guide portion γ and the auxiliary plate 10.
It is attached to the edge of the glass plate 8 via 10.

Next, the jig 1 is moved by grasping the gripping part 13c and the gripping part 15 of the lever 13 with one hand.

Then, the gasket 6 is successively attached to the edge of the glass plate 8 by the presser roller 9, and further straightened from both sides by the straightening rollers 20, 20 to ensure proper seasoning.

When the jig 1 reaches a part of the corner of the glass plate 8, the guide body 4 provided at the tip of the jig 1 in the direction of movement moves the glass plate 8 by the grip force of the hand that exceeds the biasing force of the spring 22.
The connecting body 3 moves from one side edge to the other continuous side edge, and the connecting body 3 swings upward against the spring 22.

Then, the cutting blade 5 descends together with the connecting body 3 as shown in FIG. A cut 21 as shown is formed.

This cut 21 is provided at a position where the cutting blade 5 is adjusted in advance so that the cut position by the cutting blade 5 is exactly located at a part of the corner of the glass plate 8, so it is precisely placed at a part of the corner of the glass plate 8. will be established.

When cutting the gasket 6 arranged in this way, 1
The jig 1 is moved at a corner part 1 of the glass plate 8.

In this state, the sliding portion 15b of the gripping portion 15 is pressed in the direction in which the jig 1 is retracted using an unused finger of the hand that is gripping the jig 1, for example, the index finger.

Then, the sliding part 15b moves and the recessed part of the sliding part 15b faces the protrusion 13a of the lever 13 so that it can fit therein, so in this state, the lever 13 is grasped so as to be operated toward the grip part 15. As a result, the lever 13 is operated sharply when the protrusion 13a of the lever 13 is fitted into the recess of the grip portion 15 and blocked.

Therefore, at this time, the coupling body 3 is also lowered together with the lever 13 and is attached to the coupling body.

The cutting blade 5 cuts the gasket 6.

After cutting the gasket 6, the jig 1 is moved forward along the edge of the glass plate 8, and the jig 1 is removed from the glass plate.

Then, as shown in FIG. 8, the installation of the gasket 6 is completed.

The present invention has the above-mentioned configuration, in which a guide body movable along the edge of a glass plate is swingably provided on the frame via a connecting body, a cutting blade is provided on the connecting body, and the cutting blade is provided with a guide body. When the body moves from one edge of the glass plate to the other continuous edge of the glass plate, the connecting body swings, so that the gasket passing through the frame can be cut or cut to the required depth. Therefore, the gasket cutting work, which was conventionally performed separately from the gasket capping work on the glass plate, can be performed continuously and at the same time as the gasket capping work, improving work efficiency. Accurate cutting position can be ensured.
