Description

  The present invention relates to a self-bonding tape winding tool for use by drawing out from a wound tape wound with a self-bonding tape that exerts an adhesive force when pulled, and in particular, an overhead electric wire, a sleeve cover, etc. The present invention relates to a self-bonding tape winding tool for winding and sticking a self-bonding tape around an object to be coated.

  The self-fusing tape that has been used in recent years does not stick in the state of being wound in the form of a roll even if there is no separator due to the formation of a thin film on the surface of butyl rubber. Is demonstrated. This self-bonding tape is excellent in properties such as insulation, waterproofness, and durability, and is also used as a wire wound around an overhead electric wire. The self-bonding tape exhibits an adhesive force when pulled to an intended state.

  However, the self-bonding tape changes slightly in summer and winter, and at the beginning and end when it is unwound from the wound state. The attached self-bonding tape may not be able to fully exhibit properties such as insulation and waterproofness. Therefore, when winding a self-bonding tape around an overhead electric wire, a hot wire tape winding tool that allows a quick and reliable winding operation while always applying a stable and constant tension to the self-bonding tape is disclosed in Patent Literature 1 is disclosed.

  This live wire tape winding tool includes a hollow rotator with an opening for inserting an electric wire that is freely rotatable by an insulating operation rod, a tape mounting shaft provided at an end of the hollow rotator via an attachment plate, and A guide roller and a friction roller attached to the guide roller via a swing arm are provided. Further, the swing arm is controlled to swing through a substantially bolt-shaped control shaft screwed into a required screw hole, its swing level is adjustable, and the control shaft has a swing. A biasing spring that biases the free end of the moving arm in the direction of the guide roller is provided.

  This live-line tape winding tool adjusts the swing level of the swing arm by adjusting the screwing amount of the control shaft into the screw hole, and biases the friction roller in the direction of the guide roller to back it to the self-bonding tape.

Thus, the second side plate 60 does not come into close contact with the contact plate 12 of the fixed body 10 and the base 42 of the combined body 40, and frictional force is prevented from acting.

  In this way, the tape roll 100 is held by the winding tool as shown in FIG. 3, and the self-bonding tape 101 is fed out. In order to use this winding tool, the tip of the self-bonding tape 101 fed out as shown in FIG. 1 is attached to the covering object A such as an overhead electric wire, and the winding tool is pulled down. When the covering object A is at a high place such as an overhead electric wire, it is operated by attaching the tip of the insulating operation rod to each of the attachment portions 32a and 42a of the connecting body 30 and the connecting body 40 of the winding tool. That is, when the winding tool is pulled downward by pulling the insulating operation rod, the self-bonding tape 101 is fed out while the tape winding body 100 and the fixed body 10 rotate. The self-bonding tape 101 receives a reaction force from the hooking body 70. In other words, the hooking body 70 acts as a stopper for the self-bonding tape 101, and the self-bonding tape 101 is fed out by a certain amount. Stop.

  Since the friction disk 20 is fitted into the annular groove 11 f of the fixed body 10 and the friction disk 20 is in contact with the first side plate 50, the friction force is applied to the friction plate 20 and the first side plate 50. In addition, the self-bonding tape 101 is pulled and stopped while a desired tension is applied. The self-bonding tape 101 is insulated when a desired tension is applied between the tip portion attached to the coating object A and the winding tool, and half-width wrapping is performed as shown in FIG. It is pasted so as to exhibit properties such as property, waterproofness and durability. When the self-bonding tape 101 of the tape roll 100 is used up, the winding tool is disassembled, and the new tape roll 100 is attached and used as described above.

  In addition, this invention can be variously changed within the range of the technical matter described in the claim, without being limited to the said embodiment. For example, this winding tool can be operated by hand without using an insulating operation rod, and in this case, it is not necessary to include the latching tool 70 that acts as a stopper. In this case, the first and second side plates 50 and 60 can be omitted. At this time, a frictional force is generated between the friction disk 20 and the base 32 of the coupling body 30.

  Further, as shown in FIG. 5, the winding tool can omit the coupling body 40 and the second side plate 60. In the winding tool in this case, a bulging portion 33 is provided at the tip of the coupling body 30 so that the friction disc 20 generates a predetermined frictional force.

  Further, as shown in FIG. 6, the winding tool can omit the coupling body 40, the second side plate 60, and the contact plate 12 of the fixed body 10. The winding tool in this case is such that the boss portion 11 a of the fixed body 10 has an outer diameter slightly larger than the inner diameter of the center hole 102 of the tape wound body 100, so that the tape wound body 100 does not pull out from the fixed body 10. At the same time, a bulging portion 33 is provided at the tip of the coupling body 30 so that the friction disc 20 generates a predetermined frictional force. 5 and 6 is attached with a collar 74 at the tip so that the fusion tape does not come off the roller 72.

  Further, the winding tool can be used not only for covering an overhead electric wire and a sleeve cover but also in various fields such as a golf grip and an ice hockey stick around which the self-bonding tape 101 is wound.
