Description

The present invention relates to a tape cutter that cuts and divides a tape in the longitudinal direction.

Semi-conductive tapes (called C-tapes) are used for terminals of rubber or plastic insulated cables, treatment of internal conductive layers at connections, treatment of external conductive layers, and the like. In this C-tape winding operation, the tape is wound so that the inside of the adhesive surface overlaps by about 1/2 while pulling lightly so that the tape does not wrinkle.

For example, when the C tape 5 is wound around the connection portion 3 of the insulated cables 1 and 2 as shown in FIGS. 8A and 8B, C is formed in the regions 1a and 2a between the cables 1 and 2 and the crimp terminal 4. The tape 5 is wound around the entire connection portion 3 and the terminals of the insulating cables 1 and 2.

However, the tape width of the commercially available C tape 5 is determined by the standard, and depending on the condition of the target cable, it is appropriate to use scissors 6 or a cutter in the field as shown in FIG. 8 (c). It is used by cutting it to the width of the tape.

Further, depending on the type of the target cable, it may be necessary to wind the C tape 5 at a narrow pitch, and in this case as well, the C tape 5 is cut in order to narrow the tape width. Since this cutting work involves splitting the C tape 5 having a curl in the vertical direction (longitudinal direction) with scissors 6 or a cutter, there is a risk of cutting because it cannot be cut straight.

Therefore, for example, in Patent Document 1, an internal space for mounting the tape holder is provided in the housing, the cutter is held at the bottom of the internal space, and the tape holder is rotated while pressing the tape surface against the blade portion. The tape is cut in the longitudinal direction and divided.

Further, Patent Document 2 describes a tape cutter that presses a tape width blade portion against the outer circumference of a tape with an elastic member to cut and divide the tape width at a constant level.

In Patent Document 2, the pressing force of the elastic member is adjusted so that the contact portion of the feed member is always in contact with the tape to prevent the protruding amount of the cutting edge of the tape width blade portion from becoming greater than or equal to the tape thickness. The inner layer of the tape wound in multiple layers is not cut.

A slit-shaped tape guide portion that guides the tape pulled out from the tape mounting portion along the surface of the base, and a split blade portion that cuts the tape guided via the tape guide portion in the longitudinal direction. By providing, the above-mentioned problems have been solved.

In the above configuration, the tape pulled out from the tape mounting portion is guided along the surface of the base by the slit-shaped tape guide portion, and cut in the longitudinal direction by the split blade portion. Therefore, since the split blade portion cuts the drawn tape instead of the wound tape portion, it is not necessary to adjust the thickness of the tape in consideration, and it is easy to handle in the field. Moreover, it has a strong structure with few moving parts and parts.

Further, the tape mounting portion is a rotating shaft that is attached to the base and that inserts and rotates the core material or reel of the tape, thereby solving the above-mentioned problems.

According to such a configuration, since the core material or reel of the tape may be inserted into the rotating shaft, the tape can be easily attached.

Further, the split blade portion is a cutter blade arranged so as to project from the upper surface of the first member so as to cut the tape guided through the slit-shaped gap in the first member in the longitudinal direction. By having, the above-mentioned problems were also solved.

According to such a configuration, the tape can be cut in the longitudinal direction by a cutter blade protruding from the upper surface of the first member while reducing the number of parts.

In addition, by further providing a reinforcing filament tape attached to the surface of the base, the above-mentioned problems are also solved.

According to such a configuration, the base can be reinforced with filament tape to form a stronger configuration.

Further, the tape cutter according to the present invention is attached to the contact surface with the tape in the first member, the contact surface with the tape in the second member, and the contact surface with the tape in the split blade portion, respectively. By further providing a Teflon tape for preventing the tape from adhering, the above-mentioned problems are also solved.
