Structure. By rotating the adjustment knob 11 forward and backward by this structure, the right and left sealer application width adjusting caps 8a and 8b are moved in the direction of separating and approaching each other by the reverse screw lead of the screw shaft 10, thereby opening the sealer discharge port 5. The width, that is, the sealer application width B is adjusted to be longer or shorter.
[0008]
A positioning guide sleeve 12 is screw-fitted to one end of the right and left sealer application width adjusting caps 8a and 8b so as to be movable and adjustable in the axial direction. The positioning guide sleeve 12 has an outer diameter larger than the outer diameter of the sealer application width adjusting caps 8a and 8b, and is just like a flange of the sealer application width adjusting caps 8a and 8b.
[0009]
The method of using the apparatus of the present invention having the above structure, adjustment of the sealer coating width, coating position adjustment, and coating thickness adjustment will be described below. The method of use is shown in FIGS. As shown in FIG. 3, the operator grips the work grip 1 with his / her hand, abuts the inner surface of the guide sleeve 12 on the edge of the sealer application position of the work W, puts the fingertip on the knob 7, and opens the passage 3 by the shutter 6. The sealer S is discharged from the sealer discharge port 5 of the nozzle 4 and guided along the edge of the work W by the guide sleeve 12, and the entire apparatus is moved forward to perform sealing. In a free state in which the knob 7 is not pressed with a fingertip, as shown in FIG. 4A, the shutter 6 closes the passage 3, and the sealer S of the sealer filling unit 2 moves to the sealer discharge port 5 of the nozzle 4. 4B, when the knob 7 is pressed with a fingertip, the shutter 3 rises to open the passage 3 as shown in FIG. Is discharged from the sealer discharge port 5 to seal the work W at the application position. The amount of the sealer discharged from the sealer discharge port 5 of the nozzle 4 can be adjusted by adjusting the amount of pressing the knob 7.
[0010]
Depending on the work W, adjustment of the sealer application width may be required. The adjustment of the sealer application width will be described with reference to FIG. In order to increase the application width B1 shown in FIG. 5A, the sealer application width adjustment caps 8a and 8b are separated from each other via the screw shaft 10 by, for example, rotating the adjustment knob 11 forward. As a result, the left and right end portions of the sealer discharge port 5 closed by the sealer application width adjusting caps 8a and 8b are opened to adjust the application width to the large B1.
[0011]
In order to reduce the application width B2 shown in FIG. 5B, the sealer application width adjustment caps 8a and 8b approach each other via the screw shaft 10 by, for example, reversing the adjustment knob 11. Thus, the sealer application width adjusting caps 8a and 8b close the left and right ends of the sealer discharge port 5 of the nozzle 4 to shorten the opening length and adjust the application width to the small application width B2. Therefore, the sealer application width B can be arbitrarily adjusted within the range from the large application width B1 to the small application width B2 as needed.
[0012]
Next, adjustment of the application position of the sealer will be described with reference to FIG. The application position of the sealer is an application position C from the edge of the work W to the edge of the sealer S applied to the work W. For example, it is required to adjust the size of the position where the hemming portion of the work W shown in FIG. The guide sleeve 12 is used for adjusting the application position of the sealer. That is, by rotating the guide sleeve 12 forward and backward, the guide sleeve 12 moves forward or backward with respect to the sealer application width adjusting cap 8a or 8b into which the guide sleeve 12 is screwed, and the edge of the work W The position of the edge of the sealer S can be determined by the guide sleeve 12 which comes into contact with the seal sleeve S, and the application position C can be adjusted.
[0013]
Further, adjustment of the coating thickness of the sealer S will be described with reference to FIG. This is adjusted by the diameter of the sealer application width adjusting caps 8a and 8b. That is, when the sealer application width adjusting caps 8a and 8b have a large diameter in the radial direction and a large diameter, the distance between the surface of the work W and the sealer discharge port 5 of the nozzle 4 becomes large. Is adjusted thickly. In addition, the gap between the surface of the work W and the sealer discharge port 5 of the nozzle 4 is reduced by making the sealer coating width adjusting caps 8a and 8b thin and small in the radial direction. The coating thickness is adjusted to be thin. Accordingly, the sealer application width adjustment caps 8a and 8b having different radial thicknesses in the sealer application width adjustment caps 8a and 8b are easily prepared, and the sealer S application is performed by changing and using the caps as needed. The thickness can be adjusted.
