Description

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

As a tape cutter capable of forming a folded portion at the end of the tape, the following patent document has been proposed.
In the case of Patent Document 1, two tape adhesive parts, a fixed adhesive part and a swinging plate that becomes a movable adhesive part, are provided between the adhesive tape mounted on the pedestal and the tape cutter blade installed on the same pedestal. The adhesive tape pulled out from the tape is attached to the movable adhesive part biased to the fixed adhesive part side, pulled out to the cutting blade, and after cutting, the movable adhesive part of the adhesive tape stretched between the two adhesive parts Is rotated to the original fixed adhesive portion to form a tape ring with the adhesive surface of the adhesive tape as the inner side.

  If the cut tape does not require a folded part, pull the tape upward and pull the tape upward so that it does not touch the fixed or movable adhesive part. However, there is a problem that the operability is poor and the blade is always raised upward, which is not safe.

  In the case of Patent Document 2, when the tape is pulled out and pasted to the second rotating plate and pulled out to the stopper, the blade sticks to the first rotating plate immediately before coming to the stopper and at the same time the blade comes out above the second rotating plate. Can cut the tape. At the same time, the cutting blade is rotated to the first rotating plate side together with the second rotating plate by the torsion spring provided on the cutting blade, and the tape attached to the tip of the second rotating plate and the tip of the first rotating plate The part attached to the part abuts to form a ring-like folded part, but if you do not need the folded part at the end of the tape and want to cut only, the cutting blade will be There is a problem that it is inconvenient because it is in a state of being lowered below the tip of the two rotating plates.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows the overall configuration. The tape cutter of the present invention is provided with a rotating shaft member 23 that is held detachably and rotatably at one end of a heavy support base 22. The rotating shaft member 23 is held at the intermediate portion in the length direction of the support base 22 that is configured such that the annular core 11a of the adhesive tape 11 is detachably fitted.

  The other end of the support base 22 is formed with an upright portion 24 extending to a position slightly higher than the center position of the rotary shaft member 23, and the upright portion 24 is cut with a rotary blade 37 for cutting the adhesive tape 11. A stopper 39 as a position is provided. A space between the stopper 39 and the adhesive tape 11 is a drawing path for pulling out the adhesive tape 11 that is cut to a desired length.

  A first rotating plate 30 having an adherent portion 33 at the tip is provided together with the rotating shaft 31 on the adhesive tape 11 side of the rotating blade 37. Rotate a small distance between. The second rotating plate 34 is rotatably supported by the second rotating shaft 36 and rotates to the stopper 39. A rotating blade 37 is interposed between the second rotating plate 34 and the stopper 39. Since the torsion spring 40 is provided so as to be rotatably supported by the shaft 38 and always urges the rotating blade 37 toward the tape 11, the rotating blade 37 moves the second rotating plate 34. It is pressed against the tape 11 side.

  Reference numeral 420 denotes a return stopper for determining the return position of the second rotation plate 34. When the second rotation plate 34 is stopped by the return stopper 420, the cutting blade tip of the rotation blade 37 is turned to the second rotation. The plate 34 is configured to be positioned below the front end portion 35. The distal end portion 35 of the second rotation plate 34 is bent to the first rotation plate 30 side over the entire width, and the distal end portion 35 of the second rotation plate 34 is pulled out to the stopper 39 attached to the adhesive tape from which the distal end portion 35 is pulled out. When this is done, the cutting blade portion at the tip of the rotating blade 37 is configured to protrude above the tip 35 of the second rotating plate 35 by the amount necessary for cutting the tape.

The tape cutter configured as described above is used as follows.
As shown by a solid line in FIG. 2, when the adhesive tape 11 is pulled out and the adhesive tape is attached to the tip 35 of the second rotating plate 34 and pulled out to the stopper 39, the adhesive tape 11 is pulled out immediately before the stopper 39 is reached. Since the cut tape sticks to the first rotating plate 30 and the cutting blade at the tip of the rotating blade 37 comes out above the tip 35 of the second rotating plate 34, the adhesive tape is removed by the cutting operation. Can be cut.

Simultaneously with the cutting, the rotating blade 37 is rotated in the direction of the first rotating plate 30 by the torsion spring 40, and the second rotating plate 34 is also rotated in the direction of the first rotating plate 30. When the leading end 35 of the second rotating plate 34 approaches the return stopper 420, the leading end of the rotating blade 37 falls below the leading end 35 of the second rotating plate 34, and the second rotating plate 34 to which the tape is attached. The tip 35 is stopped by a return stopper 420. At this time, a slight gap is formed between the leading end portion 35 of the second rotating plate 34 to which the leading end portion of the tape is stuck and the leading end portion 33 of the first rotating plate 30, thereby forming a loop shape. No bent portion 120 is formed. At the same time, since the first rotating plate 30 slightly returns to the tape 11 side, the tape 25 is slightly slacked and the tension is lost, so that the adhesive tape attached to the tip 33 of the first rotating plate 30 is peeled off. It will be eliminated, and the bent part 120 can be made surely.
In this state, if a tape having a folded portion at the end is required, the folded portion 120 is pinched by the hand so that the adhesive surface at the tip of the tape sticks to the opposing adhesive surface, and the folded portion is If the tape is formed and pulled out as it is and then cut, a tape having a folded portion at the cut end can be obtained.
Further, if the tape is pulled out and cut while leaving the end portion of the tape as it is, it is possible to obtain a tape that does not turn back at the cut end portion.
In this way, with a simple operation, a tape with a turn-back portion at the end and a tape without a turn-back portion can be selected and obtained as necessary.

Next, a second embodiment in which the return stopper is a movable stopper will be described with reference to FIGS. 3, 4, 5, and 6. FIG. In these drawings, reference numeral 425 denotes a movable stopper, which is configured to move up and down along the elongated hole 430. FIG. 3 is a side view showing a state in which the movable stopper 425 is lowered. Since the configuration of the other parts is the same as the configuration of the embodiment shown in FIGS. 1 and 2, the same reference numerals are given and description thereof is omitted. The usage of the tape cutter of the second embodiment will be described below. When the drawn tape is affixed to the distal end portion 35 of the second rotating plate 34 and pulled out to the stopper 39, it is also adhered to the distal end portion 33 of the first rotating plate 30 immediately before cutting the rotating blade 37. The tape can be cut by the blade portion protruding above the tip portion 35 of the second rotating plate 34. Simultaneously with the cutting, the rotating blade 37 is rotated in the direction of the first rotating plate 30 by the torsion spring 40, and the tip 35 of the second rotating plate 34 to which the tape is attached is the rotating blade as shown by the dotted line in FIG. 37 and the front end 33 of the first rotating plate 30 are brought into contact with each other, whereby a folded portion is automatically formed at the end of the tape.
When the movable stopper 425 is raised upward as shown in FIG. 5, the second rotation is achieved by cutting the tape drawn at the same position as the regression stopper 420 of the first embodiment as shown by the solid line in FIG. The plate 34 is rotated in the direction of the first rotating plate 30 by the torsion spring 40, and the distal end portion 35 of the second rotating plate 34 is stopped by the movable stopper 425 together with the rotating blade 37, and as shown by a dotted line in FIG. A slight gap is formed between the tip end portion 33 of the first rotating plate 30 and the tape is bent, which can be used in the same manner as in the first embodiment.
7 and 8 show an example of a specific structure of the movable stopper 425. FIG. Reference numeral 440 denotes a knob for moving the movable stopper 425 up and down along the elongated holes 430 and 430A, and a means for restricting unnecessary movement by adding resistance to the movement of the movable stopper 425 is added as necessary. You can also. As another method, as shown in FIGS. 9 and 10, a screw 460 with a spring 470 interposed is provided on the front upper portion of the first rotating plate 30, so that when the screw 460 is tightened, the second rotating plate 34. A gap is formed between the front end portion 35 of the first rotation plate 30 and the front end portion 33 of the first rotation plate 30, and loosening causes the front end portion 35 of the second rotation plate 34 and the front end portion 33 of the first rotation plate 30 to contact each other. The same function as moving the movable stopper 425 up and down can be given.

  The adhesive tape is mostly used as a temporary fix, and when it is securely bonded, it is rarely used from the viewpoint of durability and reliability. If it can be applied, the purpose of temporary fixing can be further achieved, and scratches and dirt can be minimized when the attached wrapping paper is peeled off.

  In addition, there is a merit that leads to ecology such that they can be reused, and since the cutting blade does not come out on the surface when not in use, it is easy to operate by installing a cutting blade with high cutting ability and cutting well. Safe to use in any environment. If the folded portion is not required, it can be simply cut, and the operation method is the same, so that it can be easily selected depending on the usage.
