  By the way, in order to improve the work efficiency of the adhesive tape attaching operation, when the adhesive tape is attached to a member to be attached such as corrugated cardboard, the length corresponding to the entire length of the region where the adhesive tape is to be attached as described above. Without sticking out and sticking so that only the tip of the adhesive tape is attached to the adherend, and then moving the main body side holding the adhesive tape, the adhesive tape is moved You may want to paste the in the pasted area. When sticking the adhesive tape in this way, unlike the configuration of the prior art described above, it is desirable to arrange the cutting blade on the non-adhesive surface side that is the surface opposite to the adhesive surface of the adhesive tape. . However, if the cutting blade is simply disposed on the non-adhesive surface side of the adhesive tape, it is difficult to form a folded portion where the outer side is a non-adhesive portion, which is convenient when peeling off from the adherend member.

  The present invention has been made from the above-described actual state of the prior art, and its purpose is that a cutting blade can be disposed on the non-adhesive surface side of the adhesive tape, and the outside is non-adhesive to the cut end of the adhesive tape easily after cutting. An object of the present invention is to provide a tape cutter device capable of forming a folded portion composed of a surface.

In order to achieve this object, the present invention provides a storage unit capable of storing an adhesive tape having an adhesive surface on one side and a non-adhesive surface on the other side, and cutting for cutting the adhesive tape drawn from the storage unit. The cutting blade is fixed to a main body arranged to be rotatable in the pulling-out direction of the adhesive tape on the non-adhesive surface side of the adhesive tape drawn out from the storage portion.

  Based on these FIGS. 7-14, the sticking operation | work in this embodiment which sticks the adhesive tape 2 on the corrugated cardboard 14 which is a to-be-adhered member is demonstrated below.

  When affixing the adhesive tape 2 to the corrugated cardboard 14, for example, as shown in FIG. 7, the palm is brought into contact with the handle 13, and the rotating roller 11 is attached to the corrugated cardboard 14 with the adhesive tape 2 accommodated in the accommodating part 3 being sandwiched between them. The tip of the adhesive tape 2, that is, the vicinity of the base of the folded portion 2 c is attached to the corrugated cardboard 14 with the rotating roller 11. And as shown in FIG. 8, the main body 1 side is moved along the pasting plan area. During this time, the torsion coil spring 33 b mounted on the columnar body 33 a of the first guide portion 33 slides on the non-adhesive surface 2 b of the adhesive tape 2 by the operation of pressing the rotating roller 11 against the corrugated cardboard 14. The second torsion coil spring 34b slides on the non-adhesive surface 2b of the adhesive tape 2, and the frame body 5 rotates in the pulling-out direction of the adhesive tape 2 against the urging force of the torsion spring 30. The cutting blade 9 rotates in the direction to open against the biasing force of the torsion spring 30.

  During this period, the large-diameter second torsion coil spring 34 b of the second guide portion 34 tends to move downward relative to the small-diameter first torsion coil spring 34 a, so that the cutting edge of the cutting blade 9 is applied to the adhesive tape 2. Keep out of contact. In addition, the roller member 12 rotates in accordance with the movement of the main body 1 and the rotating roller 11 receives a braking force of the leaf spring 35 as a brake member while receiving a light sliding resistance by the restricting member 7. While rotating. The torsion spring 30, the torsion coil spring 33 a of the first guide part 33 and the second torsion coil spring 34 b of the second guide part 34 slide on the non-adhesive surface 2 b of the adhesive tape 2.

Is disconnected. At this time, as described above, tension is applied to the adhesive tape 2 with the first guide portion 33 and the second guide portion 34 and the rotating roller 11 as fulcrums, and the cutting blade provided integrally with the frame body 5 by this tension. The adhesive tape 2 is reliably cut by the cutting blade 9 in a state in which the 9 is wide open.

Immediately after the cutting, as shown in FIGS. 10 and 11, the cutting blade 9 provided integrally with the frame body 5 by the urging force of the torsion spring 30 tries to vigorously return in the direction opposite to the pulling-out direction of the adhesive tape 2. Suruga, by cut ends of the adhesive tape 2 to be pushed back to the rotating roller 11 side cutting edge, and while temporarily contacting the second torsion coil spring 34 b of the second guide portion 34 of the cutting blade 9, the rotating roller 11 and the cutting edge of the adhesive tape 2 positioned between the cutting blade 9 and the holding plate 32 and the supporting member 17 are so close that the side facing the holding plate 32 and the supporting member 17 is convex. Can be bent. By the subsequent rotation of the frame body 5 and the cutting blade 9, as shown in FIG. 12, the cut end portion of the adhesive tape 2 is bent so as to come into contact with the curved surface portion 32a of the presser plate 32. Further, FIGS. As shown in FIG. 2, the cut end portion of the adhesive tape 2 is sandwiched between the presser plate 32 and the rotary roller 11, and the adhesive surfaces 2a of the cut end portions of the adhesive tape 2 are joined together.

After the adhesive tape drawn out from the storage portion is cut by the cutting blade, the cutting blade and the presser plate are rotated in a direction opposite to the pulling-out direction of the adhesive tape, thereby cutting the adhesive tape. A tape cutter device, wherein an end portion is sandwiched between a curved surface portion of the pressing plate and an outer peripheral surface of the rotating roller, and a folded portion including the non-adhesive surface on the outer side is formed. In the invention of claim 1 ,
The charging mechanism includes the rotating roller and a brake member that applies a rotational load to the rotating roller. When the adhesive tape is pulled out from the storage unit, the charging mechanism is placed on the rotating roller subjected to the rotational load. A tape cutter device comprising: a device that charges the pressure-sensitive adhesive tape by rubbing the pressure-sensitive adhesive tape. In the invention according to claim 1 or 2,
The adhesive tape is stored in the storage unit in a wound state,
The charging mechanism includes a friction generating member that comes into contact with an outer peripheral surface of the adhesive tape that is wound around the storage unit, and the friction generating member is removed when the adhesive tape is pulled out from the storage unit. And a tape cutter device characterized in that the adhesive tape is charged by friction with the adhesive tape. In the invention according to any one of claims 1 to 3,
When the adhesive tape is pulled out, a guide portion that contacts the non-adhesive surface of the adhesive tape and rotates the cutting blade in the pulling-out direction of the adhesive tape against the urging force of the urging member. Provided,
The charging mechanism includes the guide part, and when the adhesive tape is pulled out from the storage part, the guide part rubs the non-adhesive surface of the adhesive tape to charge the adhesive tape. A tape cutter device comprising: In the invention of claim 4,
The tape cutter device according to claim 1, wherein the guide portion includes a synthetic resin torsion coil spring extending along a cutting edge of the cutting blade.
