Description

[Detailed description of the invention] The present invention relates to a tape cutter that is useful for binding small stick-shaped items, bag openings, etc. with single-sided adhesive tape, and in particular, the free end of the single-sided adhesive tape pulled out from the tape holder. This prevents the tape from wrapping around the tape holder.

The tape cutter disclosed in Japanese Utility Model Application No. 54-128484 has a single-sided adhesive tape attached to the fuselage so that it can be pulled out to the front of the fuselage with the adhesive side facing up.
A roll of single-sided adhesive tape is rotatably supported,
A tape holder is disposed at a front position of the wound body,
A tape pressing member is provided on the lower side of the tape holder to press the back side of the single-sided adhesive tape pulled out from the rolled body to temporarily attach the adhesive side of the single-sided adhesive tape to the lower surface of the tape holder, A tape cutting blade is disposed facing upward at the front position of the tape holder.

According to this tape cutter, the tape can be pulled out to a desired length with the adhesive side facing up, so it is possible to attach the object to the adhesive side of the tape and then rotate the object. Wrapping the tape around the circumference of the object to be bound can now be performed by the natural movement of the worker's hand, eliminating the hassle of changing the tape or the object to be bound, making the tying work smoother. On the other hand, the free end of the tape extending from between the tape holder and the tape pressing member may bend upward, wrap around the tape holder, or even go over the outer circumference of the tape holder and pull out the tape midway. There are problems such as sticking to parts. In particular, when the tape is made of plastic, polypropylene, etc., static electricity is generated in the tape, which tends to cause the tape to warp easily.

An object of the present invention is to provide a tape cutter that can prevent the free end of the tape from wrapping around or sticking to the tape holder.

Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiments.

In FIGS. 1 to 3, reference numeral 1 denotes a fuselage body, and the fuselage body 1 has two side plates 2 and 3 that are parallel to each other. A horizontal support shaft 4 is installed in a cantilevered manner on the inside of one side plate 2, and the fuselage
A single-sided adhesive tape roll A is rotatably supported so that it can be pulled out to the front, that is, to the left, of the machine body 1 with the adhesive surface 5A side of the single-sided adhesive tape 5 facing up. The other side plate 3 has an opening 3A formed therein to facilitate attachment and detachment of the wound body A.

A tape holder 6 is disposed at a front position of the wound body A. This tape holder 6 has a horizontal support shaft 7
It is rotatably supported between the side plates 2 and 3 via. The tape holder 6 is preferably made of a material having excellent releasability to the adhesive surface 5A of the tape 5, such as polytetrafluoroethylene.

On the lower side of the tape holder 6, there is a tape pressing member 8 which presses the back surface 5B of the tape 5 pulled out from the rolled body A and temporarily attaches the adhesive surface 5A side of the tape 5 to the lower surface of the tape holder 6. It is provided. Here, the tape pressing body 8 is made of one springy filament, both end surfaces of the tape pressing body 8 are fixed to the side plates 2 and 3, respectively, and the intermediate portion 8A is the tape pressing body 8 itself. Tape holder 6 due to spring properties
It is in elastic contact with the bottom side of the. Note that the intermediate portion 8A of the tape pressing body 8 is positioned here so that it can come into elastic contact with the circumferential surface of the tape holder 6 slightly in front of the horizontal shaft 7 directly below.

A tape cutting blade 9 is provided at the front position of the tape holder 6.
is provided with the cutting edge facing upward. This cutting blade 9 is fixed between the side plates 2 and 3, and its cutting edge is located inside the side plates 2 and 3, so safety is high.

Reference numeral 10 denotes a warping prevention means for preventing the tape 5 from warping;
1, the proximal end of the filament member 11 is attached to one end of the support shaft 7 and fixed to the body 1, and the distal end 11A side of the filament member 11 extends upward. It extends horizontally above the holder 6, and the tip 11A is a free end. Note that this tip portion 11A may extend obliquely upward, or may have a curved shape.

When binding objects B such as rod-shaped small items and bag openings with the tape cutter having the above configuration, the tape 5 pulled out from the wound body A with the adhesive surface 5A facing up is placed between the tape holder 6 and the tape pressing body 8. and pull it further forward. Next, the objects B are placed on the adhesive surface 5A of the tape 5, and the drawn end of the tape 5 is pasted along the circumferential surface of the objects B.
The tape 5 is wound around the circumferential surface of the object B by rotating it one or more times. Thereafter, the object to be bound B is lowered in front of and below the cutting blade 9, and the tape 5 is cut by the cutting blade 9, thereby completing the binding, and the cut end of the tape 5 on the side of the wound body A is held by the tape. It is held between the body 6 and the tape pressing body 8, and the cut end is maintained in a free state protruding forward of the roller body 6. In this case, the cut end, that is, the free end of the tape 5 is warped upward, but because of the presence of the tape warp prevention means 10, it does not wrap around the tape holder 6 or stick to the middle part of the tape 6. Therefore, the next time the tape can be used easily.

Although one embodiment has been described above, the present invention is not limited to the above, but also includes, for example, the following modifications.

As shown in FIG. 3, an annular groove 12 is provided on the outer periphery of the approximately central portion of the tape holder 6, and a protrusion 13 that fits into the groove 12 is provided in the intermediate portion 8A of the tape presser 8.
The protrusion 13 and the groove 12 may constitute the tape warp prevention means 10.

In this example, due to the pressing action of the protrusion 13 on the groove 12, a deformed portion 5C extending in the longitudinal direction toward the free end of the tape 5 is formed approximately at the center thereof, so that the free end of the tape 6 is straight. This prevents the tape from being wrapped around the tape holder 6 due to warpage.

As shown in FIG. 4, the tape pressing body 8 side of the tape warping prevention means 10 may be constructed with an engaging piece 14 that fits into the groove 12 of the tape holder 6 instead of the protrusion 13. Note that the engagement piece 14 may be configured to rotate.

As shown in FIG.
The tape warping prevention means 10 may be configured by making the middle portion concave to accommodate this, and the drum-shaped outer circumferential surface 15 of the tape holder 6 and the concave portion 16 of the tape pressing body 8. This anti-curl means 10 forms a gentle curve at the cut end of the tape 5. Note that the relationship between the tape holder 6 and the tape presser 8 is such that even if the tape holder 6 has a concave central portion on its outer periphery in the shape of a drum, and the tape presser 8 has a convex intermediate portion, the same effect can be obtained. Of course. Further, the tape pressing body 8 may be simply two rod-shaped bodies without a continuous intermediate portion.

As shown in FIGS. 6A and 6B, the tape warpage prevention means 10 is constructed by fixing both ends of the filament member 17 to the body 1 and positioning the intermediate portion 17A above the cut end of the tape 5. You can.

As shown in FIG. 7, the side plates 2 and 3 of the fixed portion of the cutting blade 9 are extended upward, and a brush 18 made of highly elastic bristles fixed horizontally is provided inside the plates. The tape warp prevention means 10 may be configured to hold the cut tape 5 between the two ends. As a result, the tape 5 is prevented from warping and being wound around the tape holder 6, and there is no problem in cutting the tape 5.

As shown in FIG. 8, instead of the brush, the tape warp prevention means 10 may be constructed by fixing presser pieces 19 made of bent wire or the like above the cutting blade 9 on both sides. good.

In this example, the tape 5 is pressed down from between the presser pieces 19, 19, and the tape 5 is cut by the cutting blade 9.

As shown in FIG. 9, the support shaft 7 is a fixed shaft,
The tape warping prevention means 10 may be configured by providing a protrusion 20 projecting upward on the support shaft 7 and rotatably supporting the tape holder 6 on the support shaft 7 on both sides of the protrusion 20. .

Note that a plurality of protrusions 20 may be provided, and the tip portion thereof may have a T-shape or the like.

As shown in FIG.
It may be a tape support plate 21 extending between the three.

Although each embodiment has been described above, the present invention can of course be modified in other ways without departing from the gist of preventing the tape from being wrapped around the tape holder due to warpage.

Since the present invention has the above-mentioned configuration, the tip of the single-sided adhesive tape, which is pulled out from between the tape holder and the tape presser and supported in a free state, is warped and cut by the tape warp prevention means. The adhesive side of the end does not wrap around the roller body, and the tapes do not cross over the roller body and stick to each other, so that the next use can always be performed in an optimal state. Further, since the tape warp prevention means only requires processing some of the already provided parts or adding some simple parts, it has the advantage that it can be realized at low cost and is extremely economical.
