Description

  The present invention relates to a cutting tool for a wound belt provided with a tearing blade for a wound belt and a tearing blade for a wound belt, and a wound belt housing box.

The thin shape with respect to the planar expansion has flexibility in the thickness direction, so that it is wound up with a curl in the production, processing, distribution, storage, or consumption of articles ( In the following description, it is often handled as a winding. This is because, in general, wound articles are easy to handle because the volume occupied by the articles is small, and the exposed surface area is small, so that advantages such as reduction in quality and damage can be suppressed. It depends. Because of the above-mentioned advantages, there are a wide variety of articles to be rolled up, from materials such as woven fabrics, cloth woven fabrics, paper, resin films, metal thin plates, etc., to processed products such as various tapes and adhesive films. It is difficult to express the above-mentioned various types in a single word, but it is difficult to express them in one word. In the explanation of, the word “band” is used. Further, the term “winding shape” is used in the sense that the shape seen from the end of the winding shaft includes all flat shapes, those having a winding core, and those having no winding core.

As described above, the wound belt has advantages such as ease of handling and suppression of deterioration in quality, but the width of the belt is approximately the length of the winding shaft. The length of the band, which is the direction in which it is rolled up several times, is long. In other words, since the length of the band to be accommodated is long, it can be said that it is wound using the flexibility in the thickness direction of various articles. In the final situation such as consumption, the wound belt body is to unwind the winding body and cut the belt body into appropriate dimensions. At that time, the belt body is cut in a direction parallel to the winding axis. It is horizontal cutting that cuts the strip in a direction substantially orthogonal to the horizontal cutting direction. Each wound strip has a unique width, so if the desired width dimension is the width of the strip, the article can be cut by cutting in the same lateral direction as the winding axis direction of the strip. When the desired width dimension is smaller than the width of the strip, it is also cut in the longitudinal direction substantially perpendicular to the winding axis direction of the strip.

There are a wide variety of articles to be wound, but even if the original material is of high strength, such as metal, the one with a thin band is absolutely tough. Since it is small, for example, the band can be easily cut by moving it so as to tear it while keeping the band in contact with a simple blade provided in the storage box of the wound band. The simple blade illustrated here is called a tearing blade, and ranges from materials such as woven cloth, cloth woven cloth, paper, resin film, metal foil, etc., to processed products such as various tapes and adhesive films. It is widely used for transverse cutting of a wide variety of wound strips. For the tearing blade, in addition to the one with a simple linear tip, a substantially triangular notch is continuously formed on the cutting edge as seen on a tearing blade attached to a container for household wrap film. In addition, it has been widely known that the band body can be easily cut and an accident in which a person is injured with a sharp blade edge is considered.

As a conventional tearing blade, it is provided in a V-shaped blade provided in a carton for a wrap film disclosed in JP-A-5-338645 of Patent Document 1 and a film drawer container disclosed in JP-A-2001-240051 of Patent Document 2. There is a corrugated blade. The blade shown in Patent Document 1 is provided with a loose V-shaped blade having a fine comb-shaped cut at the edge of the blade, and is provided at a portion of the front of the wrap film box that overlaps, so a loose V-shaped blade. Although it can be seen that the center part slightly protrudes from the other part of the blade edge, it has only the function of cutting in the same lateral direction as the winding axis direction of the band, so the winding axis direction of the wound band It was impossible to cut in the vertical direction almost perpendicular to the line. The corrugated blade provided in the film drawing container shown in Patent Document 2 also has only a function of cutting in the horizontal direction, and the wound belt cannot be cut in the vertical direction.

Further, the wrap film storage box disclosed in Japanese Patent Application Laid-Open No. 7-61450 is provided with a pointed protrusion near the end of the carton as a cutting tool. However, the projection forms a hole-like or cut-like cutting point near the side edge of the film, and then cuts by tearing regardless of the blade, so the same as the winding axis direction of the wound belt It can be said that it is a cutting tool exclusively for transverse cutting.

Furthermore, the wrap film storage case disclosed in Japanese Patent Application Laid-Open No. 2003-81279 describes a cutter unit that slides in parallel with a winding shaft provided in the wrap film storage case, but the cutter unit is wound. Since it slides in the direction across the band, the band cannot be cut longitudinally. In addition, various types of film slitters are conventionally known, but these slitters are provided with a blade of a type different from the tearing blade, and can only cut a wound belt vertically. It has a structure. The conventional tearing blade has a function capable of cutting in the same horizontal direction as the winding axis direction of the band, but no one that can cut the wound band in the vertical and horizontal directions is known.

Since the wound strip has a specific width, if the desired width dimension is the width of the strip, it is sufficient to cut in the same lateral direction as the winding axis direction of the strip, but the desired width dimension is sufficient. As described above, when the width dimension is smaller than the width of the band, it is necessary to cut in the longitudinal direction substantially orthogonal to the winding axis direction of the band. Since the conventional tearing blade has only the function of cutting in the same transverse direction as the winding axis direction of the band, when it is necessary to cut in the vertical direction substantially perpendicular to the winding axis direction of the band, Separately, it was necessary to cut the strip in the vertical direction using a scissors or the like.

The present invention has been made to solve the above-described problems. Even when it is necessary to cut in the longitudinal direction substantially perpendicular to the winding axis direction of the belt body, the present invention can be simplified without using a separate hook or the like. It is to provide a tearing blade for a wound strip that can cut the strip in the vertical direction as well as in the horizontal direction, and cuts the strip not only in the horizontal direction but also in the vertical direction. An object of the present invention is to provide a cutting tool for a wound belt provided with a tearable cutting tool for a wound belt, and a wound belt housing box.

In order to achieve the above-mentioned problem, in a blade for cutting a wound belt, a sharp convex part is projected and molded on the cutting edge of a laterally cut blade that cuts the broken band in the same direction as the winding axis, The above-mentioned convex portion is a vertical cutting blade for cutting a band in a vertical direction substantially orthogonal to the cutting direction of the horizontal cutting blade.

Alternatively, in a cutting tool for cutting a wound belt, a sharp convex portion is protruded in the vicinity of the cutting edge of a horizontal cutting blade for cutting the broken strip in the same direction as the winding axis, and the convex portion is cut horizontally It is set as the tearing blade for wound strips characterized by using the longitudinal cutting blade which cuts a belt in the longitudinal direction substantially orthogonal to the cutting direction of a blade.

Further, the longitudinal cutting blade made of the convex portion is a tearing blade for a wound belt body that is movable along the cutting edge of the horizontal cutting blade, or all or the tip portion of the vertical cutting blade made of the convex portion. Is a tearing blade for a wound strip that can be stored toward the base of the transverse cutting blade.

Moreover, the winding strip | belt accommodation box provided with the cutting tool for winding strip | belt bodies provided with the tearing blade for winding strip | belt bodies described above, or the tear strip cutter for winding strip | belt strips is used.

Although the conventional tearing blade for a wound belt has only a function of cutting in the same lateral direction as the winding axis direction of the belt, the tearing blade for a wound belt of the present invention is A sharp convex part is projected on or near the cutting edge of a horizontal cutting blade for cutting the broken strip in the same direction as the winding axis, and the convex part is set in a vertical direction substantially perpendicular to the cutting direction of the horizontal cutting blade. By using a vertical cutting blade that cuts the belt, it is possible to provide a tearing blade for a wound belt that can cut the belt not only in the horizontal direction but also in the vertical direction without using additional rivets or the like. It is a thing. At the same time, it is intended to provide a wound strip cutting tool equipped with a tear strip for a wound strip that can cut the strip not only in the horizontal direction but also in the longitudinal direction, and a wound strip housing box. Is now possible.

The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a schematic explanatory view showing a main part of a torn cutting tool for a wound belt according to claim 1 of the present invention. In the figure, 1 is a tearing blade for a wound belt, 2 is a wound belt, 3 is a winding axis of the wound belt, and 4 is a broken belt. In the drawing, a cylindrical wound belt 2 is drawn behind the tearing blade 1 for a wound belt with the winding shaft 3 substantially horizontal. The torn cutting tool 1 for a wound belt body is a sharp projection that is formed by projecting on a cutting edge 6 of a transverse cutting blade 5 that cuts the unwound band 4 in the same direction as the winding shaft 3 and the cutting edge 6 of the transverse cutting blade 5. Consists of a portion 7, and the convex portion 7 functions as a vertical cutting blade 8 that cuts the broken strip 4 in a vertical direction substantially perpendicular to the cutting direction of the horizontal cutting blade 5. If the convex portion 7 is molded wide, the drag force when the strip 4 is cut in the longitudinal direction is increased, and a good cutting line may not be obtained depending on the material of the strip. The shape of the side cutting blade 5 protruding from the cutting edge is preferably formed into a sharp needle shape, a cone shape, a bowl shape, or the like. In addition, since the protrusion 7 is likely to be caught on a peripheral object if the distance by which the protrusion 7 protrudes from the cutting edge 6 of the horizontal cutting blade 5 becomes excessive, the protrusion 7 is formed in the case of a general winding band cutting tool 1. It is appropriate that the distance at which the horizontal cutting blade 5 protrudes from the cutting edge 6 is about 1 mm to 10 mm.

If the end of the band shown in FIG. 1 is held by hand and gently pulled downward, the wound band 2 will be unraveled, but if the direction of pulling the unfolded band 4 is slightly upward Then, the broken strip 4 comes into contact with the sharp convex portion 7 which is projected and formed on the cutting edge 6 of the horizontal cutting blade 5, and a hole is opened. Next, when the pulled strip 4 is further pulled with the convex portion 7 penetrating the strip 4, the strip 4 is substantially orthogonal to the winding shaft 3 by the convex portion 7. It is cut by the distance drawn in the vertical direction. After longitudinally cutting the strip body by a desired distance, when a force is applied with the direction of pulling the stripped strip 4 further upward, the stripped strip 4 comes into contact with the cutting edge 6 of the laterally cut blade 5, and the winding axis 3 is cut so as to be torn off in a lateral direction substantially parallel to 3.

On the other hand, when the end of the band is held by hand and pulled gently downward to unwind the wound band 2, if the direction in which the unfolded band 4 is pulled downwards, It is pulled out without contacting the sharp convex part 7. After the strip is pulled out by a desired distance, when a force is applied with the direction in which the strip 4 is pulled upward, the strip 4 is brought into contact with the cutting edge 6 of the horizontal cutting blade 5 and the conventional cutting blade is cut. As in the case of using, the transverse cutting of the strip 4 is completed. At the time of the horizontal cutting of the band, the broken band 4 contacts the sharp convex portion 7 that is projected and formed on the cutting edge 6 of the horizontal cutting blade 5, but the convex portion 7 originally has the cutting edge 6 of the horizontal cutting blade 5. Since it protrudes upward and is molded, a good cutting line can be obtained without the convex portion 7 becoming an obstacle to transverse cutting.

Although the cutting device 10 for wound strips of Example 5 shown in FIG. 12 is for an adhesive tape, in use, the frame 12 of the cutting device 10 for wound strips is pressed by hand, If the end of the band is held by hand and pulled gently downward, the wound band 2 is unwound. If the direction of pulling the band 4 unraveled at this time is slightly upward, the unwound band 4 Comes into contact with the sharp convex part 7 projectingly arranged near the cutting edge 6 of the horizontal cutting blade 5, and a hole is opened. Next, when the pulled strip 4 is further pulled with the convex portion 7 penetrating the strip 4, the strip 4 is substantially orthogonal to the winding shaft 3 by the convex portion 7. It is cut by the distance drawn in the vertical direction. After longitudinally cutting the strip body by a desired distance, when a force is applied with the direction of pulling the stripped strip 4 further upward, the stripped strip 4 comes into contact with the cutting edge 6 of the laterally cut blade 5, and the winding axis 3 is cut in a horizontal direction substantially parallel to 3 in the same manner as the above-described wound strip for cutting strip 1. In the wound strip cutting instrument 10 of Example 5 shown in the figure, the cutting in the vertical direction, which was impossible with a conventional adhesive tape cutting machine, can be performed with a simple operation. If you want to cut the strip 4 in the horizontal direction, you can use exactly the same operation as a conventional cutting machine for adhesive tapes using cutting blades, so it is necessary to have several types of adhesive tapes with a width that is not frequently used. There is no. .
