Here, the tightening roll 4 and the main support roll 5, the auxiliary rolls 6, 6 and the auxiliary support rolls 7, 7,
are arranged in pairs.

Cantilever brackets 8, 8 are formed extending from the fixed outer casing 2 in the front-rear direction, and the cantilever brackets 8, 8 are further provided with guide front wheels 9, 9 and guide rear wheels 9', 9. ' is rotatably supported. These guide wheels 9, 9' have flanges 9a, 9 on the outer edge along the shoulders of the outer enclosure to be tightened.
It is equipped with a′ in one piece. Reference numeral 10 denotes a motor mounted on the fixed outer casing 2, and the rotation of the motor 10 causes a gear 12 connected to the tightening roll 4 by a shaft 11 through a gear train, and a speed ratio of 1 to 1. :1, the gear 12' connected to the main support roll 5 by the shaft 11' is interlocked. 1
3, 14, and 15 are switches for normal rotation, stop, and reverse rotation of the motor 10. 16 is the fixed outer casing 2
Reference numeral 17 denotes a swinging arm that is swingably supported by a bracket 17a extending from the fixed outer casing 2. Reference numeral 17b denotes a press roller for pressing the rotatable outer casing 3 provided at the end of the swing arm 17.

Reference numeral 18 denotes a pressing roller that presses the horizontal surface of the clamping portion.

Next, the roll shapes of the tightening roll 4 and the main receiving roll 5 will be explained with reference to FIG. 4. Fourth
As shown in the figure, the tightening roll 4 has a small flange portion 4
a and a cylindrical portion 4d having an arcuate groove 4b formed thereunder and a bulging strip 4c provided at the upper end. The main receiving roll 5 has a small flange portion 5a and an arcuate groove 5b formed below the small flange portion 5a.

Next, the auxiliary rolls 6, 6 and the auxiliary receiving rolls 7, 7 disposed in pairs therewith will be explained with reference to FIG. The auxiliary roll 6 is integrally provided with a flange 6a on its lower edge, and has a tapered conical portion 6b forming a position regulating groove for regulating the position of the edge 20a of the upper ridge portion 20 of the outer envelope 19. The auxiliary support roll 7 paired with this is formed by forming a small flange portion 7a and an arcuate groove 7b below the small flange portion 7a.

Fastening machine 1 according to the present invention configured as described above
will be sandwiched between the upper part 20 and the lower part 21 of the outer enclosure 19 to be tightened, and the tightening operation will be explained.

In this tightening operation, as shown in FIGS. 3 to 5, the tightening machine 1 is mounted on the upper part of the outer enclosure 19 to be tightened. At this time, the tightening machine 1 is
The parts to be clamped are tightened in advance using a manual tightening tool (not shown). Then, with the arm 16, the tightening roll 4 and the auxiliary rolls 6, 6 of the fixed outer casing 2 are brought into contact with the upper part 20, and the guide wheels 9, 9, 9', 9' are moved around the outer enclosure 19. Place it along the shoulder. Next, the swinging arm 17 is rotated about the shaft 17c supported by the bracket 17a, and the swinging outer casing 3 is moved by the pressing roller 17b.
is fixed to the fixed outer casing 2. At the same time, the main receiving roll 5
The auxiliary support rolls 7, 7 are fitted onto the arcuate portion of the upper ridge portion 20.

In this way, after clamping the tightening machine 1 on the upper part of the outer enclosure 19, press the forward rotation switch 13 and start the motor 10.
is applied to rotate the tightening roll 4 and the main receiving roll 5 interlocked therewith.

With this, the tightening machine 1 has guide wheels 9,
9, 9', 9' while moving forward on the outer enclosure 19, the edge 20a of the upper part 20
The position of the auxiliary roll 6 is regulated and the material is sent to the rear tightening roll 4, and the tightening roll 4 and the main receiving roll 5 perform the tightening work.

The auxiliary roll 6 is capable of tightening the upper part even when the edge 20a of the upper part has been significantly deformed in the vertical direction due to variations in bending during forming, as shown by the broken line in FIG. This is to regulate and shape it to an appropriate position. The upper ridge part 20 and the lower ridge part 21 are pressed by the pressing roller 18, and are also pressed by the small flange 4a and the arcuate groove 4b of the tightening roll 4 and the main receiving roll 5.
It is watertightly tightened with the small tsuba part.

Although used in this way, the reversing switch 15
Of course, it can also be used by pressing , reversing the motor 10, and moving it backwards.

Although the locking machine according to the present invention was configured as described above,
Of course, the components such as the tightening roll and the auxiliary roll can be modified in various ways without changing the gist of the invention.

(Effects of the Invention) As explained in detail above, the locking machine according to the present invention is configured, so that the following effects can be obtained.

That is, since the small flange part and the arcuate grooves are formed in the cleat roll, the watertightness between the upper part and the lower part is higher than before when the upper part is tightened.

This eliminates the occurrence of a gap between the upper and lower parts, which could not be avoided simply by pressing the upper part with the large flange of the conventional catch roll.

An auxiliary roll is provided in front of the tightening roll in the traveling direction, and a position regulating groove for regulating the position of the edge of the upper ridge is formed in the auxiliary roll, so that the edge of the upper ridge can be prevented from dispersion during molding. Even if it deviates significantly from the designed position, it is properly positioned by the auxiliary roll, and the edge of the upper part is sent to the subsequent part tightening roll, so that the part tightening work can be carried out smoothly. This results in 1
The work was completed in just one turn, and work efficiency improved.

In this way, we have been able to provide a tightening machine with high practical value.
