Description

  The present invention relates to an adhesive tape cutting device for cutting an adhesive tape to be attached to the outer periphery of a wound element in a winding device for forming an internal element such as an aluminum electrolytic capacitor.

  Conventionally, as this type of cutting device, for example, cutting is performed by rubbing a pair of cutter blades.

As prior art document information relating to this application, for example, Patent Document 1 is known.
JP-A-11-106103

  However, in the above conventional configuration, cutting failure due to adhesive paste adhering to the cutting blade portion of the cutter blade that cuts the adhesive surface when the adhesive tape is cut, or adhering adhesive enters between the cutting cutter blades. There is a problem that the operation failure of the cutter due to.

  The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to provide an adhesive tape cutting device free from problems caused by adhesion of adhesive on the adhesive tape.

  In order to achieve the above object, the present invention has the following configuration.

  In particular, the adhesive tape cutting device of the present invention rotates a disk-shaped cutter blade whose outer periphery has a shape as a blade at high speed, and makes contact with the surface opposite to the adhesive surface of the adhesive tape to cut. For this reason, it is possible to prevent the adhesive tape from adhering to the blade surface of the cutter due to the winding of the tape material.

  As described above, the pressure-sensitive adhesive tape cutting device of the present invention has the effect of preventing adhesion of the pressure-sensitive adhesive tape to the blade surface of the cutter and preventing cutting failure due to adhesion of the glue.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the configuration of an aluminum electrolytic capacitor element winding device provided with the adhesive tape cutting device of the present invention. Winding portion comprising a winding shaft 1 driven by a winding motor 3, a holding roller 4 for holding a winding element 2 (hereinafter referred to as winding element 2) wound up to a predetermined length, and an adhesive tape A dancer roll section 14 for applying tension between unwinding sections composed of hanging shafts 12 and 13 of a strip-shaped adhesive tape 15 (hereinafter referred to as adhesive tape 15) supplied in a reel shape driven by an unwinding motor 16. The tape chuck 6 attached to the table 7 (hereinafter referred to as the upper and lower table 7) that is driven up and down by the air that supplies the adhesive tape 15 to the winding unit, and the adhesive surface at the end of the supplied adhesive tape 15 A predetermined length is wound between the presser roller 5 (hereinafter referred to as the presser roller 5) that enters and exits by air that presses against the winding element 2 from the tape surface, and the tape chuck 6 and the winding part. By a disk-shaped cutter 8 that is driven to rotate by a drive belt 9 from a disk-shaped cutter drive motor 10 attached to a table 11 that is driven back and forth by air that cuts the adhesive tape 15 on the floor (hereinafter referred to as the front and rear table 11). It is a winding device provided with the constituted adhesive tape cutting device.

  FIG. 2 shows the state of the adhesive tape 15 and the disk-shaped cutter 8 when the adhesive tape 15 is cut. Since the disk-shaped cutter 8 that rotates at high speed with respect to the adhesive tape 15 is contacted and cut from the surface of the tape material opposite to the adhesive surface, the tape material warps in the direction opposite to the cutting direction due to the resistance of the tape material at the time of cutting. As a result, the adhesive is wound around the adhesive surface side to prevent the adhesive of the adhesive tape 15 from adhering to the blade surface of the disk-shaped cutter 8.

  Subsequently, the operation of the present embodiment will be described with reference to FIGS. The winding element 2 is wound around the winding shaft 1 driven by the winding motor 3 and wound at a predetermined length. Next, the adhesive tape 15 attached to and unwound from the hanging shafts 12 and 13 is applied with tension by the dancer roll unit 14, and a certain length is applied to the tape chuck 6 attached to the upper and lower tables 7. It is held in a state where it is raised above. At this time, the upper and lower tables 7 are in the lower position. The disk-shaped cutter 8 attached to the front and rear table 11 is waiting while rotating at high speed by the disk-shaped cutter driving motor 10. At this time, the front and rear table 11 is in the rear position. The presser roller 5 stands by in a retracted state.

  First, in order to supply the adhesive tape 15 to the winding unit, the tape chuck 6 holding the adhesive tape 15 is raised to a predetermined position by the upper and lower tables 7. At this time, the end surface of the adhesive tape 15 protruding above the upper surface of the tape chuck 6 is positioned on the right side of the winding element 2 attached to the winding shaft 1 driven by the winding motor 3. Next, the pressing roller 5 is pushed out by air, and the adhesive tape 15 is pressed against the side surface of the winding element 2. After confirming that the pressure-sensitive adhesive tape 15 is pressed against the winding element 2 by the pressing roller 5, the tape chuck 6 releases the holding of the pressure-sensitive adhesive tape 15 and descends to the lower position by the upper and lower tables. In this state, the winding element 2 is rotated counterclockwise by the winding motor 3 and the adhesive tape 15 is wound around the outer periphery of the winding element 2. After the adhesive tape 15 is wound around the outer periphery of the winding element 2 a predetermined number of times, the winding element 2 is stopped from rotating, and the adhesive tape 15 is held again by the tape chuck 6. After confirming the holding of the adhesive tape 15 by the tape chuck 6, the disk-shaped cutter 8 that is rotated at high speed by the disk-shaped cutter drive motor 10 is advanced by the front and rear tables 11, and from the surface opposite to the adhesive surface of the adhesive tape 15. Contact and cut. After cutting the adhesive tape 15, the disk-shaped cutter is moved backward by the front and rear tables 11. The winding element 2 is further rotated, and the remaining adhesive tape 15 is wound around the outer periphery of the winding element 2. Thereafter, the presser roller 5 moves backward, the holding roller 4 is also released, and the winding element 2 is taken out from the winding shaft 1.

  In this way, the disc-shaped cutter 8 that rotates at a high speed makes contact with the surface opposite to the adhesive surface of the adhesive tape 15 and cuts it, so that the cutting direction depends on the resistance of the tape material at the time of cutting as shown in FIG. Prevents the adhesive tape 15 from adhering to the blade surface of the disc-shaped cutter 8 due to the tape material being warped in the opposite direction, preventing cutting failure due to adhesive adhesion, and winding The element 2 can be reliably held and formed by the adhesive tape 15.

  The pressure-sensitive adhesive tape cutting device according to the present invention has an effect that the cutting surface of the cutter for cutting the pressure-sensitive adhesive tape can prevent cutting failure due to adhesion of the pressure-sensitive adhesive tape and can improve the operation of the winding device. This is useful as a winding device for forming an internal element such as an aluminum electrolytic capacitor.
