Description

  The present invention relates to a tape winding device.

  Conventionally, a tape winding device capable of spirally winding an adhesive tape around a long member such as an electric wire has been known. For example, a tape winding device described in Patent Literature 1 below includes a rotating disk member that rotates around an electric wire with the electric wire introduced into the center. The rotating disk member is provided with a guide member for holding a part of the electric wire therebetween and an adhesive tape main body holding member for rotatably holding a roll portion of the adhesive tape. The pulled-out portion of the tape pulled out from the roll portion of the adhesive tape is inserted between the guide members with the adhesive surface facing the electric wire. The tape winding device includes an electric wire / tape fixing means for pressing and fixing the electric wire to the adhesive surface of the adhesive tape arranged along the guide member.

  The operation of winding a tape using such a tape winding device is as follows. First, the electric wire is introduced between the guide members of the tape winding device, the electric wire is pressed against the adhesive surface of the adhesive tape by the electric wire / tape fixing means, and is attached to the end of the adhesive tape. When the rotating disk member is rotated after the electric wire is attached to the adhesive tape, the drawn-out portion of the adhesive tape is pulled out, pulled out from the roll portion, and wound around the outer peripheral surface of the electric wire.

Next, an example of an operation of winding the adhesive tape 10 around the long member L using the tape winding device M of the present embodiment will be described.
First, a long member fixing step of fixing the long member L horizontally by the fixing means F is performed. At this time, the apparatus main body 20 is separated from the side of the long member L (a direction intersecting the length direction) and is on standby. The rotating part 21 of the apparatus main body 20 is set in an open state, and the opening part 27 of the housing part 26 is arranged at the same height position as the long member L and faces each other as shown in FIG. On the upper surface of the first facing portion 28F, the end of the drawer 12 of the adhesive tape 10 is placed.

  Next, a setting step of setting the apparatus main body 20 on the long member L is performed. The apparatus main body 20 is moved to the long member L side, and the long member L is introduced from the opening 27 into the housing 26. At this time, as shown in FIG. 5, when the long member L has entered the depth side from the predetermined position, the position adjustment unit 32 is pressed by the long member L, and the elastic portion 35 is elastically moved. It is in a state of shrinking. Then, the long member L is pushed back to the opening portion 27 side by a force (elastic force) of the elastic portion 35 to return to the original size, and is disposed at a predetermined position (see FIG. 6).

  Next, a tape fixing step of fixing the end of the adhesive tape 10 to the long member L is performed. The end of the drawer 12 arranged on the curved surface 31 is attached to the outer peripheral surface of the long member L arranged at a predetermined position by the position adjusting unit 32 (see FIG. 7). Here, as shown in FIG. 5, when the long member L is displaced farther than the predetermined position, the boundary between the curved surface 31 and the flat surface 34 contacts the long member L. Will be. For this reason, the drawn-out part 12 of the adhesive tape 10 may come into contact with the outer peripheral surface of the long member L as a point, and the area to which the adhesive tape 10 is attached may be insufficient. However, according to the tape winding device M of the present embodiment, since the long member L is arranged at a predetermined position by the position adjusting unit 32, as shown in FIG. Hit the surface. Thereby, the entire width of the adhesive tape 10 can be attached to the outer peripheral surface of the long member L over a sufficient length dimension, and thus, at the start of the tape winding, by the tensile force (extending force) acting on the drawer 12. The end of the drawer 12 can be prevented from peeling off. The feeding force of the adhesive tape 10 varies depending on the temperature in the use environment, the speed at which the drawer 12 is drawn out (the rotation speed of the rotary unit 21), and the like, and the size of the sticking area required at the start of tape winding is appropriately adjusted. There is a need. The operation of attaching the adhesive tape 10 (the operation of pressing the curved surface 31 against the outer peripheral surface of the long member L) is performed by raising the first facing portion 28F or lowering the second facing portion 28S. This can be performed, for example, by rotating the rotating portion 21 and pressing the first facing portion 28F against the long member L.

Next, a tape winding step of winding a tape around the long member L is performed. The apparatus main body 20 is moved in the longitudinal direction of the long member L while reciprocating around the long member L by the moving means, and the adhesive tape 10 is spirally wound around the outer peripheral surface of the long member L. When the adhesive tape 10 is wound over the predetermined length range of the long member L, the tape winding device M is stopped.

The long member L is arranged and wound around the outer peripheral surface of the long member L with the rotation of the rotating part 21, and when the long member L is set at a predetermined position between the pair of facing parts 28 </ b> F and 28 </ b> S. And a curved surface 31 having a shape curved along the outer peripheral surface of the long member L, and when the long member L is displaced from a predetermined position, presses the long member L to dispose it at a predetermined position. A position adjusting unit 32. .

  According to this configuration, when the long member L is displaced from the predetermined position, the long member L is pressed by the position adjustment unit 32 and arranged at the predetermined position, and the outer peripheral surface of the long member L follows the curved surface 31. In this state, the drawn-out portion 12 of the adhesive tape 10 arranged along the curved surface 31 can come into contact with the long member L. Therefore, it is possible to secure a sufficient area for applying the adhesive tape 10 at the start of tape winding.

  Further, the position adjusting section 32 includes an elastic section 35 that generates an elastic force by being pushed by a long member L shifted from a predetermined position. The elastic section 35 is a metal compression coil spring. Is provided at the distal end of the compression coil spring, and has a contact portion 36 made of a synthetic resin that contacts the long member L. According to this configuration, the distal end portion of the compression coil spring can be prevented from directly contacting the long member L, so that the long member L can be prevented from being damaged.

  In addition, the rotating portion 21 includes a U-shaped accommodation portion 26 that can accommodate a part of the long member L in the length direction, and a pair of opposed portions 28F and 28S are provided in the accommodation portion 26. The curved surface 31 is provided at a position closer to the open portion 27 side of the housing portion 26, and the position adjusting portion 32 is provided at the back wall portion 29 side of the housing portion 26 opposite to the open portion 27 side. ing.
