Description

The present invention relates to a tape cutter for cutting a required amount of tape wound into a roll and having one side made of cloth-like surface and the other side made of release paper.

The above-mentioned tapes are usually made by laminating release paper so as to cover the adhesive of a cloth-like part with an integrated adhesive, and the cloth-like side of the cloth-like part opposite to the adhesive is the tape. A release paper covering the adhesive forms the other side of the tape. This tape is wound and held around a cylindrical winding shaft, and the required amount is cut out and used for medical or sports taping.
Conventionally, as a tape cutter for cutting out the necessary amount of such tape, there is one described in Patent Document 1, for example.

This tape cutter consists of upper and lower plates that face each other with a gap that allows the end of the tape wound around the winding shaft to be introduced, and a cutter that holds a cutting blade whose cutting edge is oriented toward the lower plate. The cutter section is configured to move along a guide section in the tape width direction formed with an opening in the upper plate section.

In this tape cutter, the required amount of the end of the tape is pulled out from the gap between the upper and lower plates, and in this state, the upper and lower plates sandwich the tape from both sides.
The tape is then cut in the width direction by moving the cutter section along the guide section of the upper plate section.

Japanese Patent Application Publication No. 2007-237327

However, in the above-mentioned tape cutter, although it is possible to cut the tape pulled out from the gap between the upper and lower plates by moving the cutter part along the guide part of the upper plate part, the tape cut by the upper and lower plates can be cut. If the tape is not held tightly, the cutting resistance will drag the tape against the cutting blade of the cutter that moves along the guide, causing the cut surface to become distorted, wavy, or fluffy. Ta.

In addition, when trying to firmly press the upper plate against the lower plate in order to securely hold the tape so that the cut surface is not distorted, the movement of the cutter along the guide section of the upper plate may cause the upper plate to This will be hindered by the fingers and palms that press the parts. In other words, the cutter section must be moved while changing the position where the upper plate is pressed, which makes the tape cutting operation complicated, and the cutter section is interrupted intermittently, making it difficult to obtain a sharp cut surface. There is a problem that it cannot be obtained, and solving this problem has been a conventional problem.

The present invention has been made to solve the above-mentioned conventional problems, and aims to provide a tape cutter that can easily cut the required amount of tape without distorting the cut surface. The purpose is

In order to solve the above problems, the present invention provides the following tape cutter.
That is, the first aspect of the present invention is a tape cutter for cutting a required amount of tape wound into a roll and having a cloth-like surface on one side and a release paper on the other side, a cutting blade part including a cutting blade for cutting, a tape mounting surface part having a tape mounting surface for placing one surface or another surface and receiving a cutting blade from the other surface or one surface side; a slide mechanism section disposed on the tape from the other side or one side of the tape and for sliding the cutting blade section in a direction substantially parallel to the winding axis of the tape; and a cutting blade section via the slide mechanism section. and a pressing eaves portion disposed in an eave-like manner from the slide mechanism side to the tape end side in order to press the tape against the other surface or one surface of the tape.

Further, in a second aspect of the present invention, the pressing eaves section further includes a shaping blade section having a shaping blade for shaping the cut tape.

Furthermore, the third aspect of the present invention is configured to further include a tape flow regulating part for flowing the tape into the center part of the tape mounting surface part.

<Embodiment 1>
<Summary>

The tape cutter of this embodiment includes a cutting blade section including a cutting blade, a tape mounting surface section having a tape mounting surface on which a tape is placed, and a tape cutter disposed on the tape placed on the tape mounting surface. It is equipped with a slide mechanism that slides the cutting blade in a direction approximately parallel to the winding axis of the tape. It is characterized by an eave-like arrangement on the end side.

The tape cutter of this embodiment utilizes the principle of leverage, and when you press the pressure eave part, which is the point of effort, with your fingertip, the cutting blade of the cutting blade part, which is the point of action, moves onto the tape via the slide mechanism part, which is the fulcrum. Since the tape is strongly pressed against the tape on the placement surface, the tape can be sharply cut by sliding the cutting blade in a direction substantially parallel to the winding axis of the tape using the slide mechanism in this state.
At this time, since the cutting blade is pressed simply by pressing the pressing eaves part with a fingertip, it is possible to smoothly slide the cutting blade part without being hindered by the finger pressing the pressing eaves part.
<Configuration>

The tape cutter according to this embodiment is used to cut out a required amount of tape that is wound and held around a cylindrical winding shaft.
As shown in FIG. 1A, this tape cutter 0100 has a base portion (tape mounting surface portion) 0110 attached to a tape roll body 0190 formed by winding a tape 0192 around a cylindrical winding shaft 0191, and a tape roll body 0190. A holding plate part 0120 that holds the pulled out tape 0192 together with the base part 0110, a cutting blade part 0130 for cutting the tape 0192, and a cutting blade part 0130 that is approximately parallel to the winding axis 0191 of the tape roll body 0190. A slide mechanism section 0150 for sliding in the direction (in the direction of the arrow in the figure) is provided.

The base portion 0110 is made of synthetic resin and has a horizontally elongated plate shape, and is set in the tape roll body 0190 so that its longitudinal direction, which exceeds the width dimension of the tape 0192, is aligned with the direction of the winding axis 0191.

Here, the tape 0192 is made by laminating a release paper so as to cover the adhesive on a cloth-like part in which the adhesive is integrated, and in this embodiment, the tape 0192 pulled out from the tape roll body 0190 The release paper (other side of the tape) 0194 on the opposite side of the cloth-like surface (one side of the tape) 0193 contacts the base portion 0110.

Therefore, as shown in FIG. 1B, by forming the illustrated upper surface of the base portion 0110 that contacts the release paper 0194 of the tape 0192 as a smooth tape mounting surface 0111, the tape 0192 pulled out from the tape roll body 0190 can be caught. I try to prevent it from happening. Note that the surface of the tape 0192 that is in contact with the tape mounting surface 0111 may be a cloth-like surface 0193.

At this time, as shown in FIG. 1C, the side edge of the tape loading surface 0111 on the tape introduction side (upper left side in FIG. 1B, left side in FIG. 1C) is on the tape ejection side (lower right side in FIG. 1B, right side in FIGS. 1A and C). ) is formed as a long inclined surface 0113 with a gentler slope than the inclined surface 0112 formed by chamfering the side edges.

In other words, by arranging a long inclined surface 0113 with a gentle slope on the tape introduction side of the tape mounting surface 0111, the tape 0192 that has just been pulled out from the tape roll body 0190 and is about to curl up can be made to fit into the tape mounting surface 0111. ing.

Furthermore, a groove 0114 into which a cutting edge of a cutting blade 0131 of a cutting blade part 0130 (to be described later) enters is formed along the longitudinal direction of the base part 0110 between both side edges of the tape mounting surface 0111 of the base part 0110.

The holding plate part 0120 that holds the tape 0192 together with the base part 0110 is made of synthetic resin and has a horizontally long plate shape, like the base part 0110.

In this embodiment, shaft holes 0121 extending in the longitudinal direction are formed at both ends of the holding plate part 0120 on the tape introduction side, while shaft holes 0121 are formed in the tape introduction side at both ends of the base part 0110 in the longitudinal direction. A support axis 0115 is formed along the axis.

This holding plate part 0120 can be freely rotated around the support shaft 0115 (in the direction of the arrow) with respect to the base part 0110 by fitting the shaft holes 0121 at both ends into the support shafts 0115 at both ends of the base part 0110. It has become.

Then, with the holding plate part 0120 opened with respect to the base part 0110 (the state shown by the imaginary line in FIG. 1B), the tape 0192 is placed on the tape mounting surface 0111 from the gap between the base part 0110 and the holding plate part 0120. The tape 0192 is held between the tape 0192 by closing the holding plate part 0120 in this state and stacking it on the base part 0110 (by setting it in the state shown in FIG. 1A).

As shown in FIG. 1C, the cutting blade section 0130 includes a cutting blade 0131 for cutting the tape 0192 and a holder 0140 made of synthetic resin. In this case, the cutting blade 0131 has a double-edged blade with a V-shaped cutting edge, as shown in FIG. 1D, and is held in a case 0132 made of synthetic resin.

On the other hand, the holder 0140 has a flat rectangular parallelepiped shape, and has a blade holding block 0142 integrally formed in a protruding manner at the lower part of the holder 0140. This blade holding block 0142 is open downward, and a case 0132 that holds the cutting blade 0131 is fitted and held in this blade holding block 0142.

The slide mechanism section 0150 for sliding the cutting blade section 0130 includes a bottomless slide groove 0151 formed along the longitudinal direction between both side edges of the holding plate section 0120. A blade holding block 0142 that holds the cutting blade 0131 of the cutting blade part 0130 via the blade holding block 0142 also serves as a component of the slide mechanism part 0150.

Specifically, the blade holding block 0142 is slidably fitted into the slide groove 0151 with the cutting edge of the double-edged cutting blade 0131 aligned along the longitudinal direction of the holding plate portion 0120.

That is, by moving the holder 0140 having the blade holding block 0142 along the slide groove 0151, the cutting blade 0131 of the cutting blade part 0130 is slid (reciprocating) in a direction substantially parallel to the winding axis 0191 of the tape roll body 0190. (move).

At this time, slide surfaces 0143, 0143 that slide on the curved surfaces 0122 formed on the upper surface of the presser plate part 0120 are formed on both sides of the blade holding block 0142 at the lower part of the holder 0140 (both side edges of the presser plate part 0120). This allows the holder 0140 to move smoothly and stably along the slide groove 0151.

In addition, guide grooves 0152, 0152 are formed on both sides of the slide groove 0151 in the curved surface 0122 of the holding plate part 0120, and guide grooves 0152, 0152 of the holding plate part 0120 are formed on the sliding surfaces 0143, 0143 of the holder 0140. By forming the protrusions 0145, 0145 that fit freely, the holder 0140 can move more smoothly and stably along the slide groove 0151.

Further, an operating knob 0146 is integrally arranged in a protruding manner on the upper part of the holder 0140, thereby making it possible to move the holder 0140 even more easily.

In this embodiment, the case 0132 of the cutting blade 0131 is attached to the blade holding block 0142 of the holder 0140 as follows. That is, as shown in FIG. 1E, the blade holding block 0142 of the holder 0140 is inserted into the slide groove 0151 of the holding plate part 0120 with the holding plate part 0120 opened with respect to the base part 0110. In this state, the case 0132 of the cutting blade 0131 is fitted into the opening of the blade holding block 0142 of the holder 0140 and joined by welding or adhesive.

Here, a horizontal collar 0133 is arranged at the lower end of the case 0132 of the cutting blade 0131 that fits through the opening of the blade holding block 0142 of the holder 0140. This prevents the slide groove 0151 from separating from the slide groove 0151.

Note that in order to allow the blade holding block 0142 to slide smoothly in the slide groove 0151 without rattling, at least one of the holding plate portion 0120 having the slide groove 0151 and the holder 0140 having the blade holding block 0142 is selected. On the other hand, it is desirable to use, for example, polytetrafluoroethylene as the synthetic resin.

Further, in this embodiment, a pressing eaves portion 0160 extending in an eave shape from the slide mechanism portion 0150 side toward the end side of the tape 0192 is disposed on the side edge of the presser plate portion 0120 on the tape discharge side. There is. The pressing eaves section 0160 is configured to press the cutting edge of the cutting blade 0131, which is the double edge of the cutting blade section 0130, against the cloth-like surface 0193 of the tape 0192 via the slide mechanism section 0150.

That is, in this embodiment, when the pressing eaves part 0160 is pressed with a fingertip, the support shaft 0115 of the base part 0110 that rotatably supports the pressing plate part 0120 becomes the fulcrum of the lever, and the pressing eaves part 0160 becomes the point of effort. Thus, the cutting edge of the cutting blade 0131, which is the point of action, penetrates the tape 0192 and enters the groove 0114 of the base portion 0110.

In the tape cutter 0100 according to this embodiment, when pulling out the tape 0192 from the tape roll body 0190 and cutting it, first, as shown in FIG. Set it in the direction of axis 0191.

Next, with the holding plate part 0120 opened with respect to the base part 0110, the tape 0192 is drawn onto the tape mounting surface 0111 from the gap between the base part 0110 and the holding plate part 0120.
Subsequently, in this state, the pressing plate part 0120 is closed and placed on the base part 0110 to sandwich the tape 0192 (the state shown in FIG. 1A). Note that in FIG. 1F, the guide groove 0152 of the holding plate part 0120, the cutting blade part 0130, and the slide mechanism part 0150 are all omitted.

In this clamped state, as shown in FIG. 1G, when the pressing eaves part 0160 of the holding plate part 0120 is pushed in the direction of the white arrow with a fingertip, the cutting blade 0131 of the cutting blade part 0130 is moved through the sliding mechanism part 0150. Since it is strongly pressed against the tape on the tape mounting surface 0111 of the base portion 0110, the cutting edge of the cutting blade 0131 penetrates the tape 0192 and enters the groove 0114 of the base portion 0110.

In this state, hold the operation knob 0146 of the holder 0140 of the cutting blade part 0130 with your fingers, and move the holder 0140 along the slide groove 0151 of the slide mechanism part 0150 from the state shown by a straight line to the state shown by a dashed-dotted line, and then the state shown by a dashed-dot line. If the tape 0192 is slid in the direction of the arrow shown in the figure until it reaches the state shown by , a distortion-free cut surface of the tape 0192 will be obtained.
In addition, in this embodiment, since the cutting blade 0131 is double-edged, cutting can be performed even if the holder 0140 is slid in the opposite direction to the above.

In particular, in this embodiment, the opening/closing axis of the holding plate part 0120 (supporting axis 0115 of the base part 0110) that holds the tape 0192 together with the base part 0110 is aligned in the width direction of the tape 0192 along which the cutting edge of the cutting blade 0131 moves. Therefore, as mentioned above, the cutting blade 0131 can be strongly pressed against the tape 0192 on the tape mounting surface 0111 in the entire width direction of the tape 0192 by the principle of leverage, and as a result, the tape 0192 is pressed against the cutting blade 0131. There is almost no chance of being dragged.

At this time, since the cutting blade 0131 is pressed simply by pressing the pressing eaves part 0160 with a fingertip, the cutting blade part 0130 can be smoothly slid without being hindered by the finger pressing the pressing eaves part 0160.

In addition, slide surfaces 0143, 0143 that slide on the curved surface 0122 formed on the upper surface of the holding plate portion 0120 are arranged on both sides of the blade holding block 0142 at the lower part of the holder 0140, so that the cutting blade portion 0130 Movement along the slide groove 0151 can be performed smoothly and stably.

Further, guide grooves 0152, 0152 are formed on both sides of the slide groove 0151 in the holding plate part 0120, and protrusions 0145, 0145 are formed on the holder 0140 to slidably fit into these guide grooves 0152, 0152. Therefore, the holder 0140 can be moved more smoothly and stably along the slide groove 0151.
<Effect>

According to this embodiment, the required amount of tape 0192 can be easily and sharply cut without distorting the cut surface, compared to the conventional technology.
