Generally, methods for connecting pipes that transport fluids include butt welding, socket welding, flange joint, groove joint, and threaded joint. ), etc.

Among the above-mentioned piping connection methods, the screw-type connection method is used in areas where welding is not easy, and is mainly used to connect piping of 1.5 inches or less.

However, because the screw connection method has a relatively high risk of leakage, a sealing tape called 'Teflon tape' is wound and connected to the screw connection formed in pipes, etc.

In addition, when connecting fittings such as valves, nipples, and couplings that are connected to pipes, sealing tape is wound around the screw connections formed on the valves and fittings.

These sealing tapes are mainly rolled up by field workers in the field or in factories, etc. and provided to field workers.

However, the sealing tape wound in factories, etc. also had a problem of poor workability because it was wound manually by workers, and another problem was that the winding thickness of the sealing tape was different depending on the skill level of the workers.

The motor housing 128 is installed at the rear of the base 112 so that its front side faces the rear of the mounting frame 120 so as not to interfere with the sealing tape support 130 installed on the cross bracket 124.

Inside the motor housing 128 installed in this way, the winding motor 152 of the sealing tape winding unit 150 is installed, and the rotation axis 154 of the winding motor 152 penetrates the front side of the motor housing 128 and is mounted. It extends horizontally toward the opening 126 formed at the lower side of the frame 120.

Here, Figure 1 shows a state in which two sealing tape supports 130 are installed on the cross bracket 124, and similarly, a winding motor 152 of two sealing tape winding parts 150 is installed in the motor housing 128. The installed state is shown.

The sealing tape support portion 130 includes a support shaft 138 on which the bobbin (B) on which the sealing tape (S) is wound is rotatably inserted, and a support shaft housing ( 132).

The support shaft housing 132 is provided in a horizontally extending cylindrical shape, and the rear side of the support shaft housing 132 is fixedly installed on the front side of the cross bracket 124.

For this purpose, a connection flange 134 is integrally formed on the rear side of the support shaft housing 132 and is fixed to the cross bracket 124 via ordinary bolts and nuts.

Here, as anyone can see, the second contact flange 142 is formed to protrude to the outside of the support shaft 138 along the outer peripheral surface of the support shaft 138.

Meanwhile, an annular locking ring 144 is fitted to the rear end of the support shaft 138 extending to the rear of the cross bracket 124, and a ring-shaped locking ring 144 is installed on the rear end of the locking ring 144 to prevent the locking ring 144 from being separated. A fixing nut 146 is fastened to the rear end of the support shaft 137.

For this purpose, a male thread to which the female thread of the fixing nut 146 is fastened is formed on the outer peripheral surface of the rear end side of the support shaft 138.

Under the state of being inserted into the rear end side of the support shaft 138, the rear end side of the support shaft 138 is sequentially passed through the support shaft housing 132 and the cross bracket 124 to support the support shaft 138 on the support shaft housing 132.

Then, the fixing nut 146 is fastened to the support shaft 138 while the compression coil spring 148 and the locking ring 144 are sequentially inserted into the support shaft 138 extending to the rear of the cross bracket 124.

When the fixing nut 146 is fastened to the rear end of the support shaft 138, the compression coil spring 148 is compressed, and the support shaft 138 is connected to the cross bracket 124 by the restoring force of the compressed compression coil spring 148. ) moves to the rear side, whereby the rear and front surfaces of the bobbin (B) on which the sealing tape (S) is wound are elastically contacted with the first and second contact flanges (136, 142).

That is, since the back and front surfaces of the bobbin (B) on which the sealing tape (S) is wound around the first and second contact flanges (136, 142) are in elastic contact, the sealing tape is moved by the operation of the sealing tape winding unit (150). Even if (S) is released, the bobbin (B) can rotate without rolling or moving its position.

The sealing tape winding portion 150 is connected to the socket 160 into which the piping material (M) is inserted so that the screw connection portion (C) is exposed, and the sealing tape to the screw connection portion (C) of the piping material (M) inserted into the socket 160. The winding motor 152, which rotates the socket 160 so that (S) is wound, rotates the socket 160, that is, supports the end of the screw connection portion (C) exposed to the outside of the socket 160 when winding the sealing tape (S). It includes a tailstock 170 that does.

The winding motor 152 is installed in the motor housing 128 as described above, and the rotation axis 154 of the winding motor 152 penetrates the front side of the motor housing 128 and is formed in the lower part of the cross bracket 124. It extends horizontally toward the opening 126.

All or part of the remaining part of the piping material (M) excluding the screw connection part (C) is removably inserted into the holder hole 164 formed in this way, and the screw connection part (C) is exposed to the outside of the holder hole 164. faces the sealing tape (S) supported on the sealing tape support portion 130.

Here, the holder hole 164 is formed to have a cross-section corresponding to the outer shape of the piping material (M) excluding the screw connection portion (C). The holder hole 164 has a hexagonal cross-section as shown or a circular cross-section (not shown). It is formed to have.

In addition, a normal headless bolt (not shown) may be fastened to the holder 162 to secure the piping material (M) having a circular outer shape when inserting the piping material (M).

That is, in the case of the piping material (M) having a hexagonal outer shape like the head portion and nut of a normal bolt, when inserted into the holder hole 164 formed in a hexagon, it can rotate along the holder 162, but has a circular shape. In the case of the piping material (M) having an external shape, slip may occur when the holder (162) rotates, so it is necessary to secure the piping material (M) inserted into the holder hole (164) using a headless bolt.

Meanwhile, the shank coupler 166 is formed integrally with the rear end side of the holder 162 so as not to interfere with the holder hole 164, and the shank coupler 166 is formed on the rear end side of the holder 162. It extends horizontally to the outside of the rear end of.

At this time, in the shank coupler 166, a shank coupler hole 168 into which the shank 156 is detachably inserted is formed to be subducted from the rear end to the front end of the shank coupler 166, and the shank coupler hole 168 is formed at the shank coupler 166. It is formed to have a cross-sectional shape corresponding to the cross-sectional shape of (156).

That is, the socket 160 is detachably coupled to the shank 156 by the shank 156 and the ball plunger 158 inserted into the shank fastening hole 168.

The tailstock 170 includes a center 178 that supports the end of the screw connection part C when the sealing tape S is wound on the screw connection part C of the piping material M inserted into the socket 150, and a sealing tape. (S) When winding, the center (178) is supported at the end of the screw connection (C), and when separating the piping material (M) on which the sealing tape (S) is wound from the socket 160, the center (178) is held at the screw connection (C). ) includes a rotating arm 172 spaced apart from the.
