Description

[Detailed explanation of the idea] The present invention relates to a device for cutting off a strip-like member.

In recent years, synthetic resin bags such as polyethylene bags have been widely used as storage bags for various products or garbage bags. Some of these bags are made by cutting a rolled polyethylene bag along the perforations.
However, in these cases, it is inconvenient that the roll must be cut by holding it down with one hand and pulling it along the perforations with the other hand. Also,
Various storage boxes have been devised that can store roll bodies such as polyethylene bags and are provided with take-out ports from which polyethylene bags and the like can be taken out as appropriate.
However, since the shape of the outlet of such a storage box is a linear opening in a direction perpendicular to the longitudinal direction of a polyethylene bag such as a strip, it is necessary to The perforations come into contact with the entire surface of the outlet at the same time, and a large amount of force is required to cut the polyethylene, and since the surface of synthetic resins such as polyethylene bags is extremely slippery, it is actually difficult to cut them easily. It was something that could not be taken away. Such inconveniences occur not only in polyethylene bags but also in resin sheets and films, and not only in rolled strip members but also in laminated strip members.

The object of the present invention is to provide a belt-like member cutting device that can easily cut out belt-like members such as polyethylene bags, has a simple structure, and can be easily applied to containers that store belt-like members such as polyethylene bags. is to provide.

The present invention provides a slit which has a portion that is inclined with respect to the width direction of the band-like member and whose length is approximately equal to or slightly shorter than the width of the band-like member,
The above object is achieved by making the inclined portion of the slit incline to the same side regardless of the inclination angle, and by configuring the belt-like member to be inserted through the slit.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention applied to a storage box for polyethylene bags. In this figure, a slit 3 is provided on the top surface 2 of a storage box 1 serving as a storage container for the strip-like member, extending in one direction approximately diagonally from the top surface 2 and having a length slightly shorter than the width of the strip-like member. ing.
The entire slit 3 is uniformly inclined toward the same side with respect to the longitudinal edge of the upper surface 2, and
It is formed in a tapered shape so that the width becomes narrower from the left end to the right end in the figure, and a notch 4 communicating with the slit 3 is provided on one side of the approximately central portion in the longitudinal direction.

A roll body 5 of a polyethylene bag serving as a band-like member is stored in the storage box 1 so that its width direction is parallel to the longitudinal edge of the upper surface 2. This roll body 5 has perforations 6 and seals 7 at predetermined intervals.
are provided in the width direction of the roll body 5, and are configured so that a polyethylene bag 8 can be obtained by cutting from the perforation 6, and one end edge of the roll body 5 is inserted through the slit 3 and slightly exposed to the outside. It is prominent.

Next, the operation of this embodiment will be explained.

First, when one end edge of the roll body 5 slightly protruding from the slit 3 is grabbed and pulled out, the one end edge of the roll body 5 is taken out from the slit 3 to the outside of the storage box 1. At this time, since the length of the slit 3 is slightly narrower than the width of the polyethylene bag 8, the portion of the roll body 5 sandwiched by the slit 3 will be wrinkled, especially near both ends of the slit 3.

Furthermore, when one end edge of the roll body 5 is pulled in the direction of the arrow so as to almost follow the imaginary extension surface of the upper surface 2, the one end edge inside the slit 3 moves slightly to the right side in the figure; The location where the tensile force is concentrated will gradually shift from the middle left end to the right end. At this time, perforations 6 are provided at predetermined locations on the roll body 5, and in the slit 3 on the left side in the figure, one end edge of the roll body 5 is slightly wrinkled, and furthermore, the slit 3 on the right side in the figure Since the width of the roll body 5 is narrow, the one end edge within the slit 3 is prevented from shifting to the right side, so the roll body 5 is moved along the perforation from the left end to the right end in the figure. and become separated.
After the polyethylene bag 8 is completely cut off in this way, one new end edge of the roll body 5 remains, protruding from the slit 3 in a substantially triangular shape. Note that even if one end edge of the roll body 5 protruding from the slit 3 gets into the storage box 1,
When a finger is inserted through the notch 4 and one end edge of the roll body 5 is pulled out, the one end edge of the roll body 5 passes through the slit 3 and is taken out of the storage box 1.

This embodiment has the following effects.

The roll body 5 can be easily cut off along the perforations 6 by simply pulling one end piece of the roll body 5.
Moreover, since the structure is simple, it can be provided at low cost.

Further, even after the polyethylene bag 8 is cut off, the next new end edge of the roll body 5 remains through the slit 3 outside the storage box 1, making it easy to take out the polyethylene bag 8 next time. Furthermore, since the slit 3 is provided with the notch 4, even if one end of the roll body 5 is pulled back into the storage box 1, it is easy to take out the polyethylene bag 8 next time.

Furthermore, since the slit 3 is provided in a straight line, scratches in the drawing direction are less likely to occur on the surface of the drawn-out portion of the roll body 5 when the roll body 5 passes through the slit 3.

Furthermore, since the slit 3 is formed in a tapered shape that gradually becomes narrower toward the drawer side end,
One end line of the roll body 5 can be prevented from shifting toward the drawing end, and can be easily cut off by being caught in the tapered slit 3 during drawing.

In addition, in the above-mentioned embodiment, the belt-like member was explained as being a polyethylene bag, but it is not limited to this, and may be other synthetic resin bags, sheets, films, etc., or paper, etc. Good too.
Further, the belt-like member is not limited to a roll-like member, but may be a layered member that is sequentially folded. Further, even if the band-shaped member is folded along the longitudinal direction, it can be easily cut off.

Furthermore, although the slit 3 is formed into a straight line whose entire surface is uniformly inclined with respect to the width direction of the strip member, the slit 3 is not limited to this, and as shown in FIG. It may be formed parallel to the direction, or it may be a combination of multiple parts with the same inclination direction but different inclination angles as shown in Figure 3, or the inclination angle may change continuously. It may be formed in a curved shape such as a circular arc shape. In addition, although the slit 3 is formed in a tapered shape, it may be formed in a uniform width. Even if it is tilted, it can cut equally well. Furthermore, the length of the slit 3 is not limited to being slightly narrower than the width of the polyethylene bag 8, but may be approximately the same.
In short, it is sufficient that the side edges of the band-like member and the slit can come into contact with each other when being pulled out. However, forming as described above has the effect of making the cutting operation easier. Although it is not necessary to provide the notch 4, if the notch 4 is provided, it will be easier to take out the roll body 5 from a state where one end is in the storage box 1, such as when taking out the first end of the roll body 5. becomes.

Further, in the above description, the case where the present embodiment is applied to a storage container for a band-shaped member has been described, but the present invention is not limited to this. It may be something that is installed and used.

As described above, according to the present invention, it is possible to provide a belt-shaped member cutting device that can easily cut a belt-shaped member such as a polyethylene bag.
