Description

  The present invention relates to a tape cutter capable of forming a folded portion at a cut end of an adhesive tape when the adhesive tape is pulled out and cut.

  As a tape cutter capable of forming a folded portion at the end of the tape, the one disclosed in Patent Document 1 below has been proposed. In other words, as a configuration in which the adhesive surfaces are bonded together by bending the tip of the tape, when the working rod with the cutting blade attached pulls out the adhesive tape, the adhesive tape is pulled out to the cutting position and cut by the cutting operation. The collar is rotated by a spring to a roller on the tape side, to which the adhesive tape is attached, and a folded portion is formed at the tip of the tape. However, the adhesive tape is pulled out and the blade with the blade attached is pulled out to the cutting position. However, the adhesive tape may be cut unexpectedly during the extraction, and the tape may have a thin adhesive paste. The sliding blade may not rotate to the cutting position on the top.

  In the case of Patent Document 2, two tape adhesive parts, a fixed adhesive part and a swing plate that becomes a movable adhesive part, are provided between the adhesive tape mounted on the base and the tape cutter blade installed on the same base, and fixed. With the adhesive tape pulled out from the adhesive tape attached to the movable adhesive part urged by the adhesive part, pull it out to the cutting blade and move the adhesive tape stretched between the two adhesive parts with a spring after cutting By rotating the part to the original fixed attaching part, it is configured to form a tape ring with the adhesive surface of the adhesive tape inside.

  The tape pulled out in this way is affixed on the swinging plate, and the tape is pulled out to the cutting blade and cut, but it rotates with the tape sticking from the position on the tape side to the cutting blade. There is a problem that it is difficult to cut quickly.

  Further, when only the tape is cut without the need for the folded portion, the peristaltic plate is not fixed at the time of cutting, and there is a drawback that it is difficult to cut because it moves.

  The present invention solves the above-described problems and reliably provides a tape cutter with a folded portion formed at the end of the adhesive tape and a quick operation.

  A tape support part for supporting the adhesive tape on the support base and a cutting blade provided at the end are provided, and the upper end of the adhesive tape is arranged at a position where it can come into contact with the adhesive tape in the pulling process. A rotating plate is provided and a second rotating plate is provided closer to the cutting blade than the first rotating plate. The first rotating plate and the second rotating plate are connected by a connecting member and interlocked with each other. The positions of the rotation shafts of the two rotation plates are such that the movement distance of the upper end portion of the second rotation plate is larger than the movement distance of the upper end portion of the first rotation plate. And the upper end of the second rotating plate is configured so that the adhesive tape sticks during the cutting operation by the cutting blade, and either the first or second rotating plate is always on the adhesive tape side, That is, an urging means for urging in the direction opposite to the cutting blade is provided.

  By simply sticking the adhesive tape drawn out according to the present invention to the tip of the first rotating plate and cutting it by a cutting operation while pulling a small distance, it can be said that the folded portion can be automatically and quickly formed at the tip of the adhesive tape. There are advantages.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows the overall configuration. In the tape cutter of the present invention, a rotating shaft member 23 is provided at one end of a heavy support base 22 having a built-in weight (not shown) so as to be detachable and rotatable. The rotary shaft member 23 is a member to which the annular core 11 a of the adhesive tape 11 is detachably fitted, and is held at an intermediate portion in the length direction of the main body member 22.

  At the other end of the support base 22, a cutting blade 31 that cuts the adhesive tape 11 is erected on a standing part 24 that extends to a position slightly higher than the center position of the held rotary shaft member 23. A space between the cutting blade 31 and the adhesive tape 11 is a drawing path for drawing out the adhesive tape 11 to be cut to a desired length. The standing portion 24 holds a member described below necessary for forming the folded portion 12 at the cut end portion of the adhesive tape 11.

  2 and 3 show the configuration and operation of these members. A first rotating plate 33 is provided on the adhesive tape side, and a second rotating plate 34 is provided on the cutting blade 31 side. Although the lower end portion is connected by the connecting plate 30, the first rotating plate 33 has a first rotating shaft 37 above the center portion, and the tip end portion 32 of the rotating plate 33 is the cutting blade 31. Only by turning a small distance in the direction, the connecting shaft portion 39 at the lower end rotates the amplified distance by the position of the first turning shaft 37. This movement is transmitted to the second rotating plate 34 connected by the connecting plate 30 and the second connecting shaft 40, and as shown in FIG. The tip 36 is further rotated an amplified distance.

  The second rotation shaft 38 is provided with a torsion spring 35 that urges the distal end portion 36 toward the distal end portion 32 of the first rotation plate 33. Further, the distal end portions of the first rotating plate 33 and the second rotating plate 34 are bent inward at an appropriate angle over the entire width, and the distal end portion 36 of the second rotating plate is positioned at the distal end portion 32. A tip end portion 36 is formed so as to be located slightly below the portion 32.

  The tape cutter configured as described above is used as follows. The end of the adhesive tape 11 is pulled out, as shown by the phantom line in FIG. 4, the adhesive tape is pulled out, the adhesive tape is attached to the tip 32 of the first rotating plate 33, and the tape is further pulled out as shown in FIG. In this state, the tape is brought into contact with the cutting blade 31 at a desired length from the tip of the second, even though the tip 32 of the first rotating plate 33 has moved only a short distance. The front end portion 36 of the moving plate 34 is amplified and moved, hits the cutting blade 31 and stops at that position. In this state, when the front end portion of the tape is pulled down and cut by the cutting blade 31, the cut adhesive is cut. The tip end portion of the tape sticks to the tip end portion 32 of the second rotating plate 34, and the second rotating plate 34 rotates toward the first rotating plate 33 by the action of the torsion spring 35, and the tip end portion 36 rotates first. Stops in contact with the tip 32 of the plate 33 FIG. 7 shows this state, and when the tip 36 contacts the tip 32, the folded portion 12 is formed at the end of the adhesive tape. Since the portion 32 is rotated in the tape direction, the tape 25 is slightly slackened, thereby eliminating the fear that the adhesive tape attached to the tip end portion 32 will be peeled off, so that the folded portion 12 can be formed.

Next, another embodiment will be described with reference to FIG. 8. When the first rotating plate 33 is a non-ferrous metal, the iron plate 5 is pasted near the center, and the N pole of the magnet 50 is attached to the second rotating plate 34. The second rotating plate 34 is always attracted to the first rotating plate 33 side by a magnetic force by being attached so as to face the iron plate 51 side attached to the rotating plate 33. When the second rotating plate 34 is stopped by the cutting blade 31, the distance between the magnet 50 and the iron plate 51 is increased when the second rotating plate 34 is pulled out. The magnetic force returning to the one rotation plate 33 side becomes weak.

  That is, since the force to return is weakened, the surface of the magnet 50 facing the direction of the second magnet 52 is the S pole by sticking the S pole of the second magnet 52 to the magnet 50 on the inner surface of the standing part. Therefore, the S pole and the S pole face each other and the second rotating plate 34 is pushed back to the first rotating plate 33 side by the repulsive force of the magnetic force. In other words, these actions are the same as those of the torsion spring. There is an effect.

  The adhesive tape is mostly used as a temporary stopper, and when it is securely bonded, it is rarely used from the viewpoint of durability and reliability, that is, it can be easily peeled off. For example, the purpose of temporary fixing can be achieved, and it is possible to minimize damage and dirt when peeled off from affixed paper or articles, so that they can be reused.
