Abstract

PURPOSE:To easily form a tape having a desired width by pressing a blade part to the surface of a cylindrically wound tape to be stretched along the center line of said cylindrical body and cutting the tape in the direction orthogonal with the center line. CONSTITUTION:The cylindrical body 1 wound with the tape 2 around a frame body is housed into a cylindrical vessel 4 in such a manner that the tape can rotate freely around the center line. A 1st plate-shaped member 7 is mounted to the outside wall of the cylindrical vessel 4 along the center line thereof to support a 2nd plate-shaped member 18 and the blade part 9 is mounted to the upper part thereof. The blade part 9 is pressed to the desired position of the surface to be stretched along the center line of the cylindrical body 1. The tape is thereby cut in the direction orthogonal with the center line and the tape width along the center line is the desired size. The masking operation by the tape is thereby extremely facilitated.

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a tape cutter that can cut a cylindrically wound tape in a direction perpendicular to the center line of the circumferential body.

<Conventional technology> For example, when painting other parts of a floor while leaving a long straight line, if there is no masking tape with the same width as the straight line, conventional techniques Either apply tape with a width wider than the width of the straight section to the straight section and then cut off the excess tape, or apply tape with a width narrower than the width of the straight section to the straight section. A pasting method was used.

<Problems to be Solved by the Invention> In the above-mentioned conventional method, it took a long time to mask the linear portions, and the masking tape was wasted.

Means for Solving the Problems> In order to solve the above-mentioned conventional drawbacks, the present invention provides a cylindrical body (for example, a cylindrical body) formed by winding a tape around a center line (for example, the A-A line). a cylindrical body 1), and a support part (for example,
Container 4, middle cylinder 16.2B, frame 34.44, container 52)
and a blade part (e.g., blade part 9, blade part 64) that comes into contact with a desired position on a surface extending along the center line of the cylindrical body supported by the support part, The present invention provides a tape cutter configured to cut the tape in a direction perpendicular to the center line so that the tape width along the line becomes a desired dimension.

<Example> Hereinafter, the present invention will be described in detail with reference to the drawings.

In FIGS. 1(a) to (Q), 1 is a cylindrical body formed by winding a tape 3 around a frame 20, and is placed inside a cylindrical container 4 around a center line A-A. It is rotatably stored. Reference numeral 5 denotes a lid of the container 4, which is formed by a screw 6 screwed into the center of the container 4 so as not to come off from the container 4. Note that the cylindrical body 1 is aligned with the center line A within the container 4.
A ball bearing or the like may be interposed between the frame body 2 and the container 4 to facilitate rotation in the rotation direction of -A.

A first plate member 7 is attached to the outer wall of the cylindrical container 4 along the center line A-A. This plate-like member 7 has a second
A plate member 8 is supported.

The second plate-like member 8 is connected to A-A at both ends of the first plate-like member °1.
The plate member 8 is slidably engaged in a groove 71 extending along the line, and a blade portion 9 is attached to the upper surface of the plate member 8 . The blade portion 9 is composed of a blade body 91, a container 92 for storing the blade body, and a spring 93 for attaching a base portion 95 of the blade body 91 to the inner wall of the container. The spring 93 functions to press the blade 91 so that the tip of the blade 91 passes through the window 10 of the cylindrical container 4 and comes into contact with the cylindrical body 1 inside the container. Numeral 11 is a screw for fixing the second plate member 8 to the first plate member 7. 12 is a scale provided along the line A-A on the upper surface of the end of the first plate member 7 on the side of the container 4,
The dimension along the A-A line of the cylindrical body 1, that is, the tape 3
It represents the width dimension of.

Loosen the screw 11 and slide the second plate member 8 to remove the blade 9.
1 reaches a desired position on the scale 12, the screw 11 is tightened to fix the plate member 8 at that position. The tape is then pulled out through the window 10 as shown in FIG.

As shown in FIG. 2, if a stopper 94 is provided to maintain the blade 91 at a desired distance from the cylindrical body l,
This is convenient because it makes it easier to cut the tape. Note that 96 is a screw for fixing the stopper 94 to the container 92. 〇 Figure 3 shows a second embodiment of this invention 0 In the first embodiment described above, the cylindrical body l is fixed. Whereas the blade part 9 is configured to move along the line A-A, in the second embodiment, the blade part 9 is fixed and the cylindrical body 1 is moved along the line A-A. It is configured as follows.

In FIG. 3, the cylindrical body 1 is connected to the inner wall of the outer cylinder 14 and the inner wall of the inner cylinder 1.
It is rotatably stored around the center line A-A between the outer wall of No. 6 and the outer wall of No. 6. The lid is screwed onto the inner tube 16 and functions to confine the cylindrical body 1 between the outer tube 14 and the inner tube 16. The blade part 9 is fixedly attached to the outside of the outer cylinder 14 at a position where the tip of the blade body 91 can come into contact with the cylindrical body 1. An elongated groove 141 extending along line A-A is formed in the inner wall of the outer cylinder 14, and a protrusion 161 attached to the middle cylinder 16 is fitted into the groove. Due to the engagement between the groove 141 and the protrusion 161, the middle cylinder 16
can slide along the line A-A with respect to the outer cylinder 14, but cannot rotate around the line A-A. Note that the groove 141 and the protrusion 161 may be provided at one location on the outer periphery 14 and the inner periphery of the middle cylinder 16, or may be provided at several locations. A female thread is formed on the inner wall of the middle cylinder 16, and a cylinder body 20 having a male thread formed on the outer wall is screwed therein. This cylinder 20 is rotatably engaged with the outer cylinder 14 at its end, but the cylinder 20 is fixed to the outer cylinder 14 by tightening the screw 24.

When the screw 24 is loosened and the cylindrical body 20 is rotated around the A-A line, the middle cylinder 16 moves in the direction of the arrow 22 along the A-A line, so that the cylindrical body l also moves to the blade body 91. You will have to move against it. The amount of movement is measured by reading a scale (not shown) provided on the outer wall of the inner cylinder 16 through a window 26 provided in the outer cylinder 14, and when the desired amount has been moved, the screw 24 is tightened to tighten the cylinder 20. The inner cylinder 16 is fixed to the outer cylinder 14 and held at a desired position. Then, when the tape is pulled out from the cylindrical body 1, the amount of movement corresponds to the width of the tape to be cut, so that a tape with the desired tape width can be obtained.

FIG. 4 shows a third embodiment of the invention. This embodiment is slightly modified from the embodiment shown in FIG.
A male screw formed on the outer wall of the cylinder body 30 is engaged with a female screw formed on the inner wall of the cylinder body 30, and the middle cylinder 28 moves in the direction of the arrow 32. Other than these points, this embodiment is the same as the embodiment shown in FIG. Note that 281 is a protrusion on the middle cylinder 28, which corresponds to the protrusion 161 on the middle cylinder 16 in FIG.

FIG. 5 shows a fourth embodiment of the invention. This embodiment is suitable when the hollow inner diameter of the cylindrical body 1 formed by winding the tape is large. In FIGS. 5(a) and (b), 34 is a frame which sandwiches the cylindrical body l along the center line A-AK and extends in the circumferential direction of the cylindrical body l. It covers about A of the cylindrical body. A plate member 36 is attached to the frame 34 along line A-A, and a blade portion 9 is attached to the member so as to be slidable along line A-A. 38 is a screw for fixing the blade portion 9 to the plate member 36.

Loosen the screw 3 and move the blade part 9 along the A-A line,
The amount of movement is measured with a scale provided on the plate member 36, and when the desired value is reached, the screw 38 is tightened to fix the blade portion 9 to the plate member 36. Then, when the tape is pulled out from the cylindrical body 1, the amount of movement corresponds to the width of the tape to be cut, so that a tape having the desired tape width can be obtained.

FIGS. 6(a) and 6(b) show a fifth embodiment of the present invention, which is a modification of the frame 34 shown in FIG.

In this embodiment, the U-shaped member 40 and its lid member 42 constitute a frame 44 that covers approximately A of the cylindrical body 1, and the lid member 42 is attached to the U-shaped member 40 by a screw 46. . Rotatable rod-shaped bodies are disposed on the inner walls of both ends of the U-shaped member 40 and the lid member 42, so that the cylindrical body 1 can easily move inside the frame body 44. The rod-shaped body 4, which is a part of the inner wall of the U-shaped member 40, is configured to be movable relative to the cylindrical body 1 by rotation of the screw 50. This can be done by using tape etc.
This is to enable the rod-shaped body 48 to contact the cylindrical body l in an optimal state even if the thickness of the cylindrical body l changes.

7(a) and (bl) show a sixth embodiment of the present invention. Reference numeral 52 denotes a cylindrical container that accommodates a cylindrical body l rotatably around the center MA-A; A window 54 is formed in the opening 54 for pulling out the tape.

Further, a plate-shaped stand 56 is slidably attached to the outer surface of the container 52. This platform 56 is provided with a rotatable gear 58, which meshes with a groove 60 formed on the outer surface of the container 52 along line A--A.

When the knob 62 connected to the gear 5 is turned, the gear 58 moves along the groove 60, and thereby the platform 56 also moves along the line A--A. A blade 64 is rotatably attached to the tip of the stand 56, and the blade comes into contact with the cylindrical body l through the window 54 due to the pressing force of the spring 66.

A scale 68 provided on the outer surface of the container 52 indicates the width of the tape to be cut, so turn the knob 62 to move the table 56 to the desired scale position and pull out the tape at that position to cut the desired tape width. You will get a sticky tape.

In the above embodiment, either the blade or the cylindrical body is configured to move, but the mechanism for moving the blade or the cylindrical body is omitted to simplify the structure and make it disposable. Then, the positional relationship between the blade portion and the cylindrical body may be set in advance so as to obtain a specific tape width, and the two may be immovably fixed. For example, in the embodiment shown in FIG. 1, the sliding mechanism of the blade part 9 is omitted and the blade part 9 is
Alternatively, in the embodiments shown in FIGS. 5 and 7, the blade portion 9 and the base 56 may be fixed at desired positions on the plate member 36 and the container 52.

In addition, in the above embodiment, a single edge was used as the blade, but
A round blade, a needle-shaped blade, etc. may be used, or a plurality of blade bodies may be arranged in parallel. Furthermore,
In each of the above-described embodiments, a spring is used to press the blade against the cylindrical body l, but an elastic body such as rubber may also be used. Further, the strength of the spring 93.66 can be adjusted to adjust the pressing force of the blade 91.64 against the cylindrical body 1. Furthermore, Figures 3 and 4
In the illustrated embodiment, screws are used as means for fixing the outer tube 14 and the cylinder body 20.3o, but it goes without saying that various other fixing means can be used. The tape cutter of the present invention can be configured with various other structures, but further explanation will be omitted to avoid complexity.

<Effects of the Invention> As described above, the tape cutter of the present invention can easily form a tape with a desired tape width.Therefore, according to the present invention, masking work with tape can be easily performed. It becomes very easy to use, and wasteful use of tape is also eliminated.
