Description

  The present invention relates to a commercially available tape rewinding device, and more particularly to a tape rewinding device capable of reducing the tape diameter.

  2. Description of the Related Art Conventionally, a slitter device that pulls out, cuts, and winds a roll-shaped tape to change the width of the tape is known (Patent Document 1, Patent Document 2). In short, such an apparatus prevents wasteful consumption of the tape and enables the tape to be attached to a fine place.

  By the way, there is a case where it is desired to change the diameter of the tape wound in a roll shape in an operation performed in the field such as an operation of winding a tape such as a cotape around a pipe such as a drain pipe of an air conditioner. For example, piping such as a drain pipe is often placed close to the outer wall of the building from the viewpoint of improving the aesthetics of the building, and the diameter of the commercially available tape has a gap between the building and the piping. In some cases, it is difficult to wind the tape around the pipe. Moreover, when piping is curving along the projecting corner or entering corner of a building, it is necessary to wind a tape along the curving, and the work may require skill.

  As a construction method to be carried out in the above case, a tape with a small remaining amount is set aside, and the roll core around which the tape is wound is deformed into an elliptical shape, so that the tape is placed in the gap between the building and the pipe. There is a method of winding by passing the roll. That is, if the remaining amount is small, the diameter of the tape becomes small, and the diameter of the short axis can be made smaller by deforming the roll core into an ellipse, and even when the gap between the building and the pipe is small, it is allowed to pass. It is possible to wind a tape around the pipe. When this method is used, it is troublesome because it is necessary to prepare a tape with a small remaining amount, and there is a problem of contamination and deterioration when storing a tape with a small remaining amount. In addition, because the remaining amount is small, it is necessary to work while joining the tape many times, the deterioration of the design due to subtle differences in the hue of the tape and the roll core deformed into an ellipse is restored and the outer wall of the building is restored There is also a risk of injury.

  As another method, there is a method in which the tape is pulled out from the roll core, and the tape itself is manually wound on site. In this case, since the tape is wound without a roll core, a roll having a small diameter can be obtained. However, it takes time to manually wind the tape, and the operator may touch the surface or adhesive surface of the tape, which may deteriorate the adhesiveness and durability of the tape. In addition, the number of tape joints is likely to cause moisture intrusion, and in the case of piping that requires heat insulation, moisture in the heat insulation may cause frost heave damage in winter, and in the case of metal piping, the rusting rate is high. There is a problem that increases and shortens the life of the equipment.

  Accordingly, an object of the present invention is to provide a tape rewinding device that can easily change the diameter of the tape without causing a problem in the performance of the tape itself.

  The tape rewinding device of the present invention includes a driven shaft that fixes a cylindrical roll core, a drive shaft that fixes a rewind core that is smaller in diameter than the roll core and winds the tape drawn from the roll core, And a connecting portion that connects driving means for rotating the driving shaft.
