Abstract

PURPOSE:To facilitate the folding and cutting of the tape end section by forming a cutting section approachably or removably from a guide section so that the cutting section is located lower than the top edge of the guide section at the time of the approach. CONSTITUTION:A tape cutting device 10 integrally molded with an elastic member is formed in a reversed-U shape, a tape guide section 14 is formed on one end side, and a tape cutting section 18 is formed on the other end side. The guide section 14 and the cutting section 18 are made approachable or removable from each other using a base section 12a as a fulcrum so that a cutting edge 16 is located lower than the top edge of the guide section 14 when the cutting section 18 is pressed to approach the guide section 14. According to this constitution, when the cutting section 14 is pressed, the tape between the temporary lock section 20 of the cutting section 18 and the top edge 22 of the guide section 14 is expanded upward, and the tape end section can be simply folded by being picked and extracted. If no folding is required, the normal cutting may be performed without pressing the cutting section.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting device for tape-shaped bodies, and more specifically, it is suitable for cutting adhesive cellophane tape (hereinafter referred to as adhesive tape). This invention relates to a cutting device used for.

[Prior art and its problems]

Conventionally, as a means of cutting adhesive tape such as Sellotape (trade name) wound around a core, a cutter mechanism made of thin steel plate having a serrated blade in the radial direction of the wound adhesive tape is attached in a saddle-like manner. Then, there is a method of cutting the pulled out adhesive tape with a serrated blade, or a method of winding the tape around the core in the mounting groove of the base main body, which is formed by arranging the core mounting groove and the serrated blade with a predetermined distance apart. A widely used method is to attach the adhesive tape that has been removed, and then cut the pulled-out adhesive tape with a serrated blade in the same manner as described above.

However, such conventional cutting means only have a single function of cutting adhesive tape, so
For example, if adhesive tape needs to be removed after use, it is necessary to fold back the end of the adhesive tape in advance, but this folding process is complicated and troublesome. Was.

[Means for solving problems]

Therefore, the present invention includes a guide section perpendicular to the tape pulling direction, and a tape cutting section located in front of the guide section and having a cutting blade on the top edge, and the cutting section is set relative to the guide section. By forming the adhesive tape so that it can move toward and away from the guide, and by configuring the tape cutting section so that the cutting blade is located below the top edge of the guide when the tape cutting section is close to the guide section, folding and cutting operations of the adhesive tape to be pulled out can be performed. This allows the process to be performed continuously and smoothly.

In this case, if the guide part and the tape cutting part are integrally formed by bending an elastic plate member, the structure can be simplified and the manufacturing cost can be reduced. By forming a tape temporary fixing part on the inside of the cutting blade facing the guide part and slanting the top edge of the guide part downward in the direction opposite to the tape pulling direction, folding of the adhesive tape can be made easier. This is preferable because it can be achieved reliably.

[Effect]

In the tape cutting device according to the present invention, the adhesive tape pulled out through the guide part is cut by the cutting blade of the tape cutting part, and when this cutting part is pressed and brought close to the guide part, the cutting part and the guide The part of the adhesive tape located between the two parts bulges upward, and by pinching and pulling out this bulging part, the adhesive tape can be cut in a naturally folded state.

〔Example〕

Next, preferred embodiments of the tape cutting device according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, a tape cutting device 10 according to the present invention includes a main body 12 that is bent into a substantially U-shape using a highly elastic synthetic resin plate, and one end of this U-shaped main body 12 A tape guide part 14 that is perpendicular to the drawing direction of the adhesive tape A, which will be described later, is formed on one side, and a tape cutting part 18 having a sawtooth metal cutting blade 16 is provided oppositely to the other end part. The main body base 12
When the cutting blade 16 is pressed in the direction of the guide part 14 using a as a fulcrum and brought close to it, the cutting blade 16 touches the end of the guide part 14 (later-described locking part 2).
2 end edges).

In this case, the tape temporary fixing part 20 and the locking part 22 are formed by extending the edge parts of the cutting part 18 and the guide part 14 obliquely upward and downward, respectively.
A mounting piece 24 extends downward from the end of the tape cutting portion 18, and the waist portion of the tape cutting portion 18 is drawn or provided with an appropriate number of ribs 26 to improve elastic strength.

In the present embodiment, the main body 12 is made of a synthetic resin plate, but if a steel plate is used, the cutting blade 16 can be formed by making a serrated cut at a predetermined location of the tape cutting part 18 and standing it up. If the remaining portion is further bent diagonally upward to form the tape temporary fixing portion 20, it can be formed from a single plate member (see FIG. 3).

The tape cutting device Wlo according to the present invention configured as described above has a mounting piece 24 as shown in FIG. It is installed and fixed in use.

Next, the operation of the tape cutting device according to the present invention constructed as described above will be explained with reference to FIG. 4.

That is, the adhesive tape A wound around the core is attached to the temporary fixing part 2 of the cutting part 18 via the fixing part 22 of the tape guide part 14.
0 (see Figure 4a).

In this state, in order to cut the end of the adhesive tape A folded back to a desired length, press the cutting part 18 with your fingers in the direction of the guide part 14 with the base 12a as a fulcrum.
Since the temporary fixing part 20 extends diagonally upward and the cutting blade 16 including the temporary fixing part 20 is located below the edge of the fixing part 22, the temporary fixing part 20 and the fixing part 22 The tape portion a between the two bulges upward (see Figure 4b).

Next, this portion a is pinched and the cutting portion 18 is returned to its original position using its elasticity, that is, the position shown in FIG.
(See Figure C and Figure 4d).

If you just want to cut the end of the tape A to a desired length without folding it back, insert your finger into the space between the guide part 14 and the cutting part 18 and pull out part a and cut it with the cutting blade 16. (See Figure 5).

Further, FIG. 6 shows that the present invention is realized by forming an oblique locking part 22 at the top of the tape pull-out guide part 14 of the tape cutter main body 28 and extending the tape cutting part 18 from the lower part of this guide part 14. This is an embodiment in which the tape cutting device according to the above is configured as a part of the tape cutter, and in this case as well, it not only has the same effect as the above-mentioned embodiment, but also reduces manufacturing costs because it is built-in in advance. This makes it possible to easily handle the design as a whole.

〔Effect of the invention〕

As mentioned above, according to the tape cutting device according to the present invention, the end of the adhesive tape can be folded and cut continuously and smoothly, so there is no need to fold it again after cutting. It is possible to improve the efficiency of peeling work, and the structure is simple, so it can be manufactured at low cost.
Furthermore, it has various advantages such as being able to perform cutting as before, if necessary.

Although the preferred embodiments of the tape cutting device according to the present invention have been described above, the present invention is not limited to these embodiments (various design changes may be made without departing from the spirit of the present invention). Of course you can get it.
