Description

[Detailed description of the invention] Industrial applications The present invention relates to an adhesive tape cutting device.

Conventional technology Traditionally, adhesive tapes used for pasting memo paper, etc.
It is mainly wound into a roll.

There are various types of adhesive tape cutting devices (not shown), but one that is placed on a tabletop has a spool that rotatably holds the adhesive tape, and a device that is placed at a certain distance from the spool. Some have a cutting part erected at the center.

In such a configuration, one turn of the adhesive tape is pulled out to a desired length and cut by the cutting section. At this time, the length of the adhesive tape to be drawn out can be arbitrarily determined by one operator, so that the adhesive tape can be cut to a desired length.

Problems to be Solved by the Invention The adhesive tape cutting device as described above is effective because it can cut adhesive tape to a desired length. Here, as a usage of such adhesive tape, for example, there are cases where it is assumed that it will be peeled off later, such as sealing a medicine bottle. In this case, the entire surface of the adhesive tape cut by the conventional adhesive tape cutting device as described above is stuck to the object, so it is not easy to peel it off. In many cases, the adhesive tape tears and a portion remains. Therefore, the adhesive material tends to remain on the surface of the object, which may make the object dirty.

Means for solving the problem A tape holding part is provided to rotatably hold the adhesive tape wound in a roll, and a tape cutting part is provided to cut the adhesive tape pulled out with the adhesive side facing down. A paper holder that holds the release paper so as to face the adhesive surface of the adhesive tape is biased upward by an elastic member so that it can be freely moved up and down. A paper cutting means is provided for cutting the paper in conjunction with the sinking of the paper holder, and a paper feeding means is provided for feeding the release paper a predetermined length onto the paper holder after cutting the release paper.

Function: A paper holder that holds a long and thin release paper so as to face the adhesive surface of the adhesive tape is biased upward by an elastic member so that it can be freely moved up and down. By providing a paper cutting means that cuts the release paper in conjunction with the sinking of the paper holder, it is possible to cut the release paper on the paper holder when attaching adhesive tape with the assumption that it will be peeled off later. When the edge of the adhesive tape is pressed, this release paper is cut with a part protruding from the side edge of the adhesive tape, resulting in an adhesive tape with release paper attached to one end, and this release paper After cutting the release paper, the next release paper is automatically prepared on the paper holder by providing a paper feeding means for feeding the release paper a certain length onto the paper holder.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 5. Note that the same names are used for the same parts as in the conventional example described above, and descriptions thereof will be omitted. First, the adhesive tape cutting device 1 of this embodiment includes a tape holder 2 which is a tape holding part made of synthetic resin or the like, a spool 4 which rotatably holds the adhesive tape 3, and a tape cutting device 1 for cutting and rolling the adhesive tape 3. It is comprised of a paper holder 6 and the like to which the release paper 5 wound around the paper is supplied. Therefore, this paper holder 6 will be explained. Here, the paper holder 6 is composed of a holder base 7, a slider 8 which is a paper holding section, an arm 9 which is a paper feeding means, the release paper 5, and the like. Therefore, the holder base 7 has a box-shaped slider guide part 10 erected on the side from which the adhesive tape 3 is pulled out, into which the slider 8 fits, and on the right side thereof, the release paper 5 is rotatably mounted on a shaft. A paper support section 11 is formed to support the paper. Further, on the right side of the upper surface of this slider guide section 10, the release paper 5 is connected to a paper cutter 12, which will be described later.
A horizontal platform-shaped bed portion 13 is formed to cut the sheet, and the paper cutter 12 and the bed portion 13 form a sheet cutting means. Therefore, the slider 8 is fitted into this slider guide portion IO via a spring 14 which is an elastic member. The upper surface of the slider 8 has a concave shape with paper guides 15 and 16 erected on the front and rear sides, and a saw blade-shaped tape cutter 17, which is a tape cutting section, is attached to the front surface of the paper guide 15. ing. Further, the upper right side of the slider 8 is formed into a frame shape, and the paper cutter 12 is attached to the left side of the slider 8, and a paper presser 18 facing the bed portion 13 is mounted on the inner side of the upper surface via a spring 19. installed. Furthermore, on the lower right side of this slider 8,
A cam 20 with an inclined lower surface is attached.

On the other hand, the arm 9 has a plate-shaped feed member 22 with a pointed lower edge attached obliquely to the inside of an opening 21 at the upper end formed in a frame shape. The release paper 5 is fed out only to the left. Furthermore, a cam lever 24 having a cam roller 23 attached to its tip is protruded from the lower left side of the arm 9.

The lower end of the arm 9 is pivotally supported by the lower part of the holder base 7, a spring 25 is obliquely attached between the right side surface of the arm 9 and the holder base 7, and the cam roller 23 is connected to the cam of the slider 8. While in contact with the lower edge of 20, it is biased to the left and can swing freely.

In addition, the arm 9 that has swung to the left is held, for example,
A delay device (not shown) is provided to open the adhesive tape 3 in conjunction with its movement.

In such a configuration, first, the roll-shaped release paper S rotatably attached to the paper holder 11 is pulled out,
For example, as illustrated in FIG. 3, the paper guide 15° 16 on the slider 8 is sequentially inserted through the gap between the opening 21 and the feeding member 22, the gap between the bed portion 13, the paper presser 18, and the paper cutter 12. Place it in between.

So, take the tip of the adhesive tape 3 that you pulled out.

It is pressed against the release paper 5 on the slider 8 to adhere it.

When the slider 8 is pressed downward against the elastic force of the spring 14, the release paper 5 is cut between the paper cutter 12 and the bed portion 13, and becomes a release paper piece 5'. At this time, the arm 9 swings to the right against the elastic force of the spring 25 due to the cam 20 of the slider 8 sliding downward and the cam roller 23 of the cam lever 24 being pressed. Here, since the release paper 5 is held between the bed section 13 and the paper presser 18, it can be slid relatively to the left between the opening 21 of the arm 9 and the feeding member 22. Become. Then, when the adhesive tape 3 is pulled out by the desired amount, the slider 8 loses the pressing force from above.
returns upwards. Then, the adhesive tape 3 is freely cut by the tape cutter 17 on the front surface of the slider 8. At this time, the arm 9 that had been swinging to the left also swings to the right and returns to the predetermined position, and in accordance with the amount of swing of the arm 9, a new release paper 5 of a predetermined length is moved onto the slider 8. It will be sent to the top. The adhesive tape 3 thus cut has a release paper piece 5' stuck to one end.

Further, after the above-described work is completed, the front edge of the adhesive tape 3 is stuck to the upper edge of the tape cutter 17, as illustrated in FIG.

Therefore, in order to attach the release paper 5 to the adhesive tape 3, it is sufficient to simply press the adhesive tape 3 from above. It will be affixed at a position 2 to 3 m+ away from the front edge of. Therefore, as illustrated in FIG. 5, the obtained adhesive tape 3 has an adhesive portion 3' on the end side of the release paper piece 5', and the release paper piece 5' may not float. It can be seen that it can be attached flatly to the object without any problems. And, such adhesive tape 3 is
