Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter that manually cuts a substantially columnar or substantially cylindrical object in the radial direction.

[0002]

2. Description of the Related Art Conventionally, scissors, guillotine type cutters, or knives have been used to manually cut a substantially cylindrical or cylindrical object in the radial direction.

Conventionally, a pipe cutting tool disclosed in Japanese Patent Laid-Open No. 6-8034 and a Japanese Patent Laid-Open No. 2000-2791 have been proposed as those capable of easily cutting a pipe into small circles with a small force.
A cutter and the like described in Japanese Patent Publication No. 56 have been proposed.

[0004]

However, since the scissors and the guillotine type cutter are push-cut, not only a large force is required to cut the object to be cut, but also the cut surface is crushed. There was a problem of being lost.

On the other hand, when a knife is used, it does not require a large force for cutting because it can be pulled and cut, but there is a problem that a technique is required to cut the cut surface cleanly.

Further, since the pipe cutting tool described in Japanese Patent Laid-Open No. 6-8034 and the cutter described in Japanese Patent Laid-Open No. 2000-279156 are bound to a pipe having a predetermined diameter, their versatility is limited. There was a problem.

The present invention has been made in view of the above points, and it is possible to easily and manually cut a substantially cylindrical or substantially cylindrical object without requiring a large force, and it is versatile. The purpose is to provide a cutter.

[0008]

The invention according to claim 1 is
A cutter having a pair of opposing cutting blades, and a support mechanism that supports the cutting blades so that the distance between the pair of cutting blades can be changed, while sandwiching an object to be cut with the pair of cutting blades, The cutter is characterized in that the support mechanism and the object to be cut are moved relative to each other to cut the object to be cut in a pull-cut state.

According to the present invention, the object to be cut sandwiched between the pair of cutting blades is cut in the pull-cut state by moving relative to the support mechanism, so that a large force is not required and the cutting surface Is also clean, easy and safe.

The relative movement which should be in the pulling-off state is performed in a direction substantially orthogonal to the direction in which the cutting blade hits the object to be cut, and the support mechanism and the object to be cut are aligned with each other along the axis of the object to be cut. It includes rotating relative to each other as a center.

According to a second aspect of the present invention, in the cutter according to the first aspect, the pair of cutting blades are supported by the support mechanism at a predetermined interval so as to sandwich the object to be cut,
The support mechanism is a cutter including an elastic body that elastically deforms when the distance between the pair of cutting blades is narrower than the predetermined distance.

According to the present invention, even if the distance between the pair of cutting blades is narrowed to hold the object to be cut, the original distance is restored by the restoring force of the elastic body. No need to go back to.

Further, since the sandwiching force is reduced by the restoring force of the elastic body, it is easy to adjust the sandwiching force. In other words, if the force of pinching is too strong, it will be in a push-out state,
When the object to be cut is soft, the object to be cut may be deformed and it may be difficult to move the object relatively, but according to the present invention, it is easy to sandwich the object to be cut so as not to deform it.

The invention according to claim 3 is the cutter according to claim 1 or 2, wherein the pair of cutting blades are arranged in parallel.

According to the present invention, since the pair of cutting blades are arranged in parallel, the object to be cut can be reliably sandwiched.

That is, if the pair of cutting blades is not parallel, such as scissors, the object to be cut may slip in a direction in which the distance between the cutting blades is wide when sandwiching the object to be cut. According to this, slip is prevented.

A fourth aspect of the present invention is the cutter according to the first, second or third aspect, wherein the cutting blade is a replaceably fixed cutter.

According to the present invention, the cutting blade 2 can be replaced if necessary, so that if the cutting blade is deteriorated, the cutting effect can be maintained by maintaining the desired cutting effect by replacing the cutting blade appropriately. Can be used for.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.

The cutter of this embodiment is used to cut off a tip end portion of a mayonnaise tube type plastic container having a mouth.

Nowadays, there is an increasing demand for reduction of the amount of garbage, and the number of local governments that separates and collects plastic containers for recycling is increasing. When the mayonnaise collected after the expiration date has been collected, the contents are taken out at the time of recycling, and those suitable for use are provided for farmed fish or livestock food.For example, in the case of a mayonnaise container, the container has a mouth. Since it is small, the tip part is cut off with the cutter of this example to facilitate the taking out of the contents.

The configuration of the cutter of this example will be described below with reference to FIGS. 1 to 3.

The cutter 1 of this embodiment comprises a pair of cutting blades 2 and 3 facing each other in parallel, and a support mechanism 4 for supporting the pair of cutting blades 2 and 3 so that the distance between them can be changed. There is.

In the case of this example, the support mechanism 4 includes a pair of guide rails 5 provided in parallel, a movable cutting blade support portion 6 that slides on the guide rail 5, and a fixed portion provided at the end of the guide rail 5. The cutting blade support portion 7 is a component.

The movable cutting blade support portion 6 holds one cutting blade 2 by
The fixed cutting blade support portion 7 supports the other cutting blade 3, respectively. When the moving cutting blade support 6 slides on the guide rail 5, one cutting blade 2 moves in parallel, and the distance between the cutting blades 2 and 3 is changed.

The guide rail 5 has a slide groove 51 formed in the longitudinal direction of the cylinder and is formed in a C-shaped cross section.
A coil spring 8 is provided inside the slide groove 51 of the guide rail 5.

Sliding parts 61 for sliding in the slide grooves 51 of the guide rail 5 are provided at both left and right ends of the movable cutting blade support part 6. The sliding portion 61 is formed in a shape corresponding to the cross-sectional shape of the slide groove 51 of the guide rail 5, and the coil spring 8 is fixed to the lower end thereof.

The cutting blade 2 is fixed to the central portion of the movable cutting blade supporting portion 6 by a screw 63 together with the cutting blade pressing portion 62. If the screw 63 is loosened and removed, the cutting blade pressing portion 62
The cutting blade 2 can be removed, so that the cutting blade 2 can be replaced if necessary. Therefore,
If the cutting blade 2 deteriorates, it can be maintained for a desired cutting effect by replacing the cutting blade 2 as appropriate, and it can be used for many years.

Since the movable cutting blade support portion 6 is supported by the coil spring 8, the cutting blades 2 and 3 are supported at an interval such that the mayonnaise container, which is an object to be cut, can be sandwiched therebetween.

The fixed cutting blade support 7 is provided on the substrate 71,
A pair of holding portions 72 for holding the cutting blade 3 and the coil spring 8
And a pair of coil spring fixing portions 73 for fixing the.

One of the sandwiching portions 72 is fixed on the substrate 71, the other is removable, and the cutting blade 3 is fixed by screws 74. On the upper surface of the holding portion 72, a concave portion 7 corresponding to the tip portion of the mayonnaise container which is the object to be cut
5 are provided. Also in this case, the clamping portion 72 and the cutting blade 3 can be removed by loosening and removing the screw 74, and thus the cutting blade 3 can be replaced as needed.
Therefore, when the cutting blade 3 is deteriorated, by exchanging it appropriately, the desired cutting effect can be maintained and it can be used for many years.

The method of using the cutter of this example will be described below with reference to FIGS. 4 and 5.

First, the cutter 1 is held in one hand, the mayonnaise container 9 is held in the other hand, and the tip portion of the mayonnaise container 9 is inserted between the cutting blades 2 and 3 of the cutter 1.

Next, the movable cutting blade support portion 6 is pushed down to sandwich the mayonnaise container 9 between the cutting blades 2 and 3.

At this time, the coil spring 8 is elastically deformed by pushing down the moving cutting blade support portion 6.

Further, the cutting blades 2 and 3 may be used for the mayonnaise container 9.
When the mayonnaise container 9 is rotated around the axis line with the sandwiched between, the mayonnaise container 9 is cut by the cutting blades 2 and 3 in a pulled-out state.

Since the mayonnaise container 9 is made of flexible plastic, if the sandwiching force is too strong, the container will be deformed and it will be difficult to rotate it.
Since the force of pinching is reduced by the restoring force of, the amount of pinching can be adjusted easily.

As the cutting blade 3 bites into the mayonnaise container 9, the mayonnaise container 9 enters the recess 75, which prevents the mayonnaise container 9 from being deformed.

In this example, the concave portion 75 is provided only on the fixed cutting blade support portion 7, but it may be provided on both the fixed cutting blade support portion 7 and the moving cutting blade support portion 6.

When the cutting work is finished, the cutting blades 2 and 3 return to their original intervals by the restoring force of the coil spring 8 if the force of the hand is released, so that the cutting blades 2 and 3 can be used for the next cutting work. No need to go back to the original interval.

When the cutting blades 2 and 3 become less sharp, they can be replaced with new ones.

According to the cutter of this embodiment, since the cutter is cut in the pull-cut state, it does not require a large force as compared with the case of pushing and cutting with scissors or the like, and is simpler and safer than the case of pull-cutting with a knife. . The cut surface is also right at the right angle to the axis.

As a modification, the support mechanism 4 is composed of a pair of guide rails 5 provided in parallel and two moving cutting blade support portions 6 that slide on the guide rails 5, and these two moving cutting blade support portions are provided. The cutting blades 2 and 3 may be supported by 6, respectively.

As described above, the cutter of this embodiment sandwiches the object to be cut by the pair of cutting blades 2 and 3 and moves the support mechanism 4 and the object to be cut relative to each other to cut the object to be cut. Since it cuts, it does not require much force, the cut surface is clean, and it is simple and safe.

Further, the pair of cutting blades 2 and 3 are supported by the support mechanism 4 at a predetermined interval so as to sandwich the object to be cut,
Since the support mechanism 4 includes an elastic body that elastically deforms when the distance between the pair of cutting blades is narrower than the predetermined distance, even if the distance between the pair of cutting blades is narrowed in order to sandwich the object to be cut. The restoring force of the elastic body causes the cutting blade to return to the original distance, so that it is not necessary to return the cutting blade to the original distance after use, and it can be used for an object to be cut having a slightly different diameter.

Further, since the sandwiching force is reduced by the restoring force of the elastic body, it is easy to adjust the sandwiching force.
It is easy to pinch the object to be cut so as not to deform it.

Further, since the pair of cutting blades 2 and 3 are arranged in parallel, the object to be cut can be reliably sandwiched.

In the above-mentioned specific examples, the cutter of the present invention was described as an example in which the tip portion of the mayonnaise container was cut, but the present invention is not limited to such cutting of the container, but may be covered. The copper wire is reused by removing the outer coating of the electric wire, and is used for an appropriate object to be cut such as cutting a package of packaging coins in which a plurality of sheets are stacked.
