Abstract

PROBLEM TO BE SOLVED: To provide a tape cutter that, in a single operation, doubles a coil-side cut end of a pressure-sensitive adhesive tape and forces these two folds to stick to each other so that a tab-like portion is formed at the tape end. SOLUTION: Uncoiling a pressure-sensitive adhesive tape A rotatably supported on a core shaft 8 on a main body 2 and cutting the tape A with a cutting edge 3 leaves the coil-side cut end of the tape A stabbed with prongs 13. Operating a lever 6 to rotate a roller 4 first draws the prong-stabbed portion of the adhesive tape A in between the roller 4 and a tape receiver 5 where it doubles, and next presses a projection 14 on it to cause the two folds to stick to each other.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutter having a function of folding a coil-side cut end of a coil-wound adhesive tape so that an adhesive surface thereof overlaps and attaching the folded portions to each other.

[0002]

2. Description of the Related Art A tape cutter is designed to rotatably support a coil-wound adhesive tape with a core shaft passing through a coil center hole of the tape, and to feed out the adhesive tape to an appropriate length with a tape cutting blade attached to a main body arm. It is configured to cut into pieces. This tape cutter has a convenient function, such as one that presses the tape stuck to the target location sequentially with a roller while feeding out the tape, one where the cutting blade moves by one-touch operation, and the tape is cut. There are many.

[0003]

A conventional tape cutter,
Above all, the hand-held (so-called handy type) tape cutter attaches the cut end on the coil side to the tape supporting surface near the cutting blade when cutting the adhesive tape (hereinafter also referred to simply as tape), and the part that has been extended from there to the coil The tape end floats in the air to make it easier to pick up the end of the tape at the next use.However, this structure may cause the tape end to peel off from the tape support surface and adhere to the outer periphery of the coil again. The extension of the end is very hard.

[0004] The adhesive tape fed from the tape cutter adheres to the mating surface over the entire length. For example, in the case of a packaging adhesive tape having a strong adhesive force, it is not easy to pinch and peel off the tape if both ends of the tape adhere to the box when opening a box or the like sealed with the tape.

Therefore, it has been considered that the cut end on the coil side of the tape is folded in two, and the adhesive surfaces at that portion are adhered to each other. With this arrangement, the folded portion rises without adhering, so that the user can pick it up and perform the next tape feeding or peeling off of the pasted tape.

However, it is very troublesome to fold and cut the cut end on the coil side every time the tape is cut.
Loss of labor and time is not negligible when packing a lot.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tape cutter in which a coil-side cut end can be folded and attached by a one-touch operation.

[0008]

In order to solve the above-mentioned problems, in the present invention, a tape cutter is constituted as follows.

That is, it has a core shaft and an arm portion which protrudes radially outward from the core shaft installation portion. The core shaft is passed through a coil center hole of an adhesive tape wound with a coil, and the core shaft is used to form the adhesive tape. A main body that rotatably supports the coil, a tape cutting blade that is attached to the arm and provided in front of the adhesive tape in the feeding direction, and a core that is parallel to the core axis at the arm and rotatably supports the fixed position. A roller provided between the tape cutting blade, a tape receiver provided close to the roller and closer to the core shaft than the roller, a roller for driving the rotation of the roller attached to the main body, and a roller which is rotated by the lever. Biasing means for applying a return rotational force to the roller, a piercing needle that pierces the outer periphery of the roller near the coil-side cut end of the adhesive tape, and a ridge that hits the tape receiver at a position where the roller is rotated a predetermined angle from the original position. When the roller is rotated by the lever operation, the pin insertion portion of the adhesive tape is drawn between the roller and the tape receiver, and the cut end on the coil side of the adhesive tape with the adhesive surface up is folded in two. The tape was sandwiched between the ridge and the tape receiver.

The tape cutter may further include a means for locking the roller at a position where the ridge hits the tape receiver and locking the roller with a lever, a lever or an operating force transmitting portion between the lever and the roller. preferable.

[0011]

In the tape cutter of the present invention, when the tape is cut by the cutting blade, a protruding needle on the outer periphery of the roller sticks near the cut end of the tape on the coil side. When the lever is pulled in this state, the roller rotates, and the pin insertion portion of the tape is drawn between the roller and the tape receiver, whereby the tape end is folded in two. Then, the ridges on the outer periphery of the roller which are simultaneously displaced press the folded portion of the tape against the tape receiver, whereby the adhesive surfaces of the folded portion adhere to each other. Accordingly, the operation only requires pulling the lever, which is very convenient when the tape is repeatedly applied.

When the roller is in the original position, the protruding needle is dangerous because it protrudes outward. Therefore, when the cutter is not used, the roller is rotated to a position where the outer peripheral ridge hits the tape receiver, and the roller is stopped at that position to prevent rotation. Should be hidden.
