[0004]

[Problems to be solved by the device]

 To devise a tape cutter that can always cut the tape with the same length, if you devise a mechanism that allows the user to somehow know when pulling out the tape, that the same length is pulled out, Can be solved by conventional techniques.

Therefore, an object of the present invention is to provide a mechanism in which, when the tape is pulled out by the same length, it can be visually recognized visually and the pulling out of the tape is stopped.

[0006] Further, by simplifying the mechanism without using electric power or the like, the manufacturing cost can be reduced, anyone can easily use it with one hand, and the factor that causes a failure can be minimized.

[0007]

[Means for Solving the Problems]

 The main body (7) of the present invention machine is a removable tape holder (9) with a holder shaft (8), a leaf spring (10) for giving resistance to rotation of the holder shaft (8), a guide shaft, a plate. It incorporates a rotating plate (2) with a shaft and a pedestal (12) with a cutting blade (11).

The holder shaft (8) can be attached to and detached from the main body (7), and when the holder shaft (8) is attached to the main body (7), the leaf spring (10) constantly presses the holder shaft (8), 8) Resist the rotation.

The guide shaft (13) is fixed to the main body (7), the plate shaft (14) integral with the rotating plate (2) can be attached to and detached from the main body (7), and the plate shaft (14) can be attached to the main body (7). ), The position of the putt shaft (14) is located above the guide shaft (13) at an angle of about 30 degrees.

The rotating plate (2) is in a state where it can freely rotate about the plate shaft (14) and is in a position where it does not hit the guide shaft (13) when rotated.

The cutting table (12) with the cutting blade (11) is also in a position where it does not hit when the rotating plate (2) rotates, and the height of the upper surface of the cutting table (12) is the rotating plate (2). Is horizontal, it is at the same height as the bonding surface A (15) of the bonding stick (3) and the bonding surface B (16) of the bonding stick (4).

The rotating plate (2) includes a plate shaft (14), an adhesive rod (3) and an adhesive rod (4) having a circular cross section and the same thickness, a screw A (17), a screw B (18), A lock nut A (19), a lock nut B (20) and a length adjusting dial (21) are incorporated.

The screw A (17) and the screw B (18) are opposite to each other, and are integrated with the length adjusting dial.

The adhesive rod a (3) and the adhesive rod b (4) are incorporated in the rotating plate (2) so that they can move freely toward and away from each other, and the threaded portion A (22) A screw A (17) and a screw B (18) are screwed into the screw-in portion B (23), respectively.

Therefore, the adhesive rod (3) and the adhesive rod (4) of the rotating plate (2) are loosened by the lock nut A (19) and the lock nut B (20) and the length adjusting dial (21) is removed. When turned, they move closer to or further from each other depending on the direction of rotation.

The adhesive surface a (24) of the adhesive rod a (3) and the adhesive surface b (16) of the adhesive rod b (4) are at right angles to the plate axis (14) in order to facilitate the peeling of the tape. There are several grooves cut in the direction.

The tape (1) is used by mounting it on the main body (7) having the above-mentioned mechanism. The mounting method is as follows. First, mount the tape (1) on the tape holder (9) and then mount the tape (1). When the tape end (6) is pulled out, the holder shaft (8) is attached to the main body (7) so that the tape adhesive surface (5) faces downward.

The tape end (6) from the tape (1) mounted on the main body (7) is attached to the adhesive rod (3), the adhesive rod (4), and the cutting table (12) from the lower side of the guide shaft (13). The tape end (6) with the cutting edge (11).

With the rotating plate (2) horizontal, the tape adhesive surface is adhered without slack between the adhesive surface A (15) to the adhesive surface B (16) and the cutting blade (11). A (15), a bonding surface B (16), and the cutting table are bonded.

After the above-mentioned mounting, the tape (1) is always ready to be pulled out by the same length and cut, and then the tape middle portion (25) or the tape end (6) can be pinched with the fingers and the front side. When the tape is pulled out, the adhesive plate of the tape is always adhered to one or both ends of the rotating plate (2), and the rotating plate stops half a turn as the tape is pulled out.

By repeating this, as the rotating plate (2) stops half a turn and stops, the withdrawal of the tape also stops, so if the tape is pulled down at this time, the tape is cut and its length is It is always the same length.

[0022]

[Work]

 Loosen the lock nut A (19) and lock nut B (20) of the rotary plate (2) and turn the length adjustment dial (21) to enclose the adhesive stick (3) and the adhesive stick (4). The length of (26), that is, an elliptical length from the adhesive surface A (15) to the adhesive surface B (16), the adhesive surface b (27), and the adhesive surface a (24) to return to the adhesive surface A (15). Adjust so that the tape length is twice the length you want to cut, and tighten the lock nut A (19) and lock nut B (20).

When the tape end (6) is pulled out from the tape (1), the tape (1) with the tape holder (9) is attached to the main body (7) with the tape adhesive surface facing downward. .

The tape end (6) is pulled out from the lower side of the guide shaft (13) to the adhesive stick (3), the adhesive stick (4) and the upper side of the cutting table (12), and the tape end is cut (11). ).

With the rotating plate (2) horizontal, the tape is adhered to the adhesive surface A (15) to the adhesive surface B (16) to the cutting blade (11) without slack. The attachment surface A (15), the adhesion surface B (16), and the cutting table (12) are adhered.

The tape middle part (25) or the tape end (6) is grasped with a finger, the tape is lifted up, and peeled from the cutting table (12). At this time, the tape may be peeled from the adhesive surface B (16), but is not peeled from the adhesive surface A (15).

Next, when the tape is to be pulled out to the front upward, since the tape is adhered to the adhesive surface A (15), a force is applied to the adhesive surface A (15) in the tape pulling direction.

Since the adhesive surface B (16) has several grooves cut and the plate shaft (14) is above the guide shaft (13), the adhesive surface area of the adhesive surface B (16) with the tape is large. Is smaller than the adhesive area of the adhesive surface A (15) with the tape.

When a force for pulling out the tape is applied in a state where the tape is adhered to both the adhesive surface A (15) and the adhesive surface B (16), the force applied to the upper end of the adhesive rod a (3) is The resultant force of pulling out the tape and the reaction force from the upper end of the adhesive rod a (3) to the center of the plate shaft (14) and the force from the adhesive rod a (3) to the guide shaft (13) via the tape. become.

Since the force applied from the adhesive rod (3) to the guide shaft (13) via the tape is a resistance force within a certain range when the tape is pulled out through the guide shaft (13), , As the pulling force of the tape is increased, the resultant force applied to the upper end of the adhesive stick (3) is applied upward.

Therefore, when the pulling force of the tape is increased, the adhesive rod B (4) starts moving downward, the adhesive surface B (16) is peeled off from the tape, and the adhesive rod a (3) is fixed at the portion where the tape is attached. The tape is rotated in the direction in which the tape is pulled while moving to the adhesive surface a (24) side.

When the tape is further pulled, the adhesive portion between the tape and the adhesive rod (3) is completely moved to the adhesive surface a (24), and at the same time, the adhesive surface b (22) is also adhered to the tape.

From this point, when the tape is pulled down horizontally, the adhesive surface b (27), the adhesive surface a (24), and the cut table (12) become horizontal.

At this time, when the tape is lowered slightly downward, the tape adheres to the cutting table, the rotation of the rotary plate (2) is stopped, and when the tape is pulled further downward, the tape is cut by the cutting blade.

At this time, since the rotating plate (2) has rotated half a turn, the length of the drawn tape is the length of the elliptical shape (26) surrounding the adhesive rod (3) and the adhesive rod (4). Which is half the length of the cut tape.

Therefore, after the tape is cut, the tape end (6) or the tape middle portion (25) of the tape attached to the cutting table (12) is again pinched with a finger, and the tape is repeatedly drawn and cut. For example, the cut tapes will have the same length.

【Example】

 If the machine of the present invention is used as a conventional cutter such as cellophane tape, it can always cut to the same length.

In addition, if the mechanism is such that the cutting blade (11) of the cutting table (12) of the present invention machine is not attached, the tape having the same perforation from the beginning is cut for each perforation. Can be used for

Due to its mechanism, the machine of the present invention can be used for most of hard tapes such as metal tapes and tapes with one side or both sides having an adhesive surface, unless the tape is extremely thick and soft.

Depending on the tape, the leaf spring (10) and the cutting blade (11) of the cutting table (12) are unnecessary, and depending on the application, the mechanism for adjusting the rotating plate (2) may be omitted.

[0041]

[Effect of device]

 If the machine of the present invention is used, for example, to seal a large number of identical envelopes with tape, work efficiency is improved without having to measure the length of the tape to be cut each time the tape is cut.

The time and labor for cutting the tape that is too long and the waste of the tape associated therewith are eliminated, and since ordinary tape can be cut with one hand, the work efficiency is improved even when the cut tape is put on an article.

If the tape is always used for cutting with the same length, it can be used for various purposes.

Further, since it is a simple mechanism that does not use power such as electric power, the manufacturing cost can be reduced, and the cause of failure is extremely small.
