Description

The present invention is a technique for preventing the insertion of a foreign object that does not cut a finger, a part of clothes, a metal plate, or the like or inhibits a cutting function by bending the insertion path of the paper insertion portion for shredder cutting. It is about.

Currently, when cutting paper with a shredder, there are painful accidents such as a part of clothing accidentally getting caught, or a child inserting a finger and a finger that has been detected and cut by both hands. is happening. In addition, there are not a few accidents in which the blade of the cutter is damaged by the insertion of foreign matter such as a metal plate or hard plastic. In particular, accidents that cut fingers are a social problem.

These are all because the insertion path of the shredder cutting paper insertion part has been designed only to be suitable for paper insertion, and the shredder that constitutes a straight path suitable for paper insertion In many cases, ergonomic considerations for accident prevention are not made.

Problems to be solved by the invention

The present invention bends the insertion path of the above-mentioned paper insertion portion into a shape that prevents insertion of a finger or the like, thereby preventing the insertion material from going straight at the time of insertion, thereby preventing erroneous insertion action or insertion insertion of an inappropriate insertion material. It is to prevent.

Means for solving the problem

In order to solve the above-described problem, the shredder insertion path according to the present invention extends at least in parallel with the side of the paper or film that is to be cut toward the paper insertion portion, and the cutting paper insertion portion. When the direction of the surface spreading around is a plane direction, the paper insertion section path extends in the vertical direction with respect to the plane direction, and forms the paper insertion section path and the paper insertion section path. The cross-sectional shape showing the shape in the elevation direction of the provided paper guide wall is the opposite of the direction in which each of the plurality of curves swells the one paper guide wall in all or part of the paper insertion section path. And the other paper guide wall is similarly formed in a generally S-shaped curve, and the cross-sectional shape is formed along the extending direction of the paper insertion path. Extend and share In addition, the curved surface formed by continuously forming the width formed by the paper guide wall of the insertion path so as not to impair the prevention effect by bending is the first unsuitable material such as a fingertip, metal plate, hard The insertion of the second unsuitable material such as a plate is prevented, and this prevents the material from being carelessly cut.

Further, the shredder insertion path of the present invention described below has at least a paper insertion section path and a cross-sectional shape showing the shape in the elevation direction of the paper guide wall provided oppositely that forms the paper insertion section path. Are formed in a generally J-shape with a curve having the bulging direction in the same direction, and are continuous along the extending direction of the paper insertion path, so that the first and the first of the fingertip, metal plate, hard plate, etc. This prevents the unsuitable cutting of 2 from being inserted and prevents them from being cut unintentionally.

Further, the shredder insertion path of the present invention described below is the paper insertion section path of the paper guide wall provided oppositely, or a part of either one of the surfaces of the cutting paper, By providing an automatic paper feed roller for smooth insertion and delivery, it is possible to smoothly insert paper to be cut even in the winding paper insertion path. Further, in the present invention, even when the roller is actuated on the unsuitable material for cutting, the paper insertion section path is not delivered to prevent insertion, and safety is maintained.

The invention's effect

Since the conventional shredder insertion path is straight toward the cutting cutter as shown in Fig. 1, it has an efficient structure for cutting paper and the like, but there is a risk that the fingertips will be inserted by mistake. On the other hand, if the width of the insertion slot is narrowed to prevent erroneous insertion and the insertion is restricted, the number of sheets to be cut is reduced and the cutting efficiency is lowered.
The shredder insertion path of the present invention provides these disadvantages as a simple and inexpensive structure, and as a structure that prevents near-perfectness.
That is, among the first and second unsuitable materials for cutting, especially the finger plays the role of inserting the cut material into the insertion slot in most cases, but the risk prevention depends only on the attention of the inserting person. In the present invention, the finger is bent in one direction by the joint in the present invention, while the paper is bent flexibly, for example, in an S shape, so that an insertion path continuing from the insertion port is formed. As shown in FIGS. 2 to 5, the shape of the formed paper guide wall is a curved surface that is opposite to the insertion direction, so that the paper can be delivered to the cutting cutter while being bent. No matter which side is inserted from the left or right side of the insertion port, it cannot be delivered because it is blocked by one of the opposite curved surfaces as shown in FIG.
Further, as shown in FIG. 6, the shredder insertion path of the present invention forms an insertion path that continues from the insertion port, and has a cross-sectional shape that indicates the shape in the elevation direction of the paper guide wall that is provided oppositely. Is formed by a curve formed in the same direction, and is formed by continuing along the extending direction of the paper insertion portion path. The curved surface that bends papers and can be delivered to the cutting cutter has a fingertip, a metal plate. By preventing the unsuitable cutting material such as a hard plate from being inserted or making it difficult to reach, it is possible to prevent these from being cut unintentionally.
Further, the shredder insertion path of the present invention is for cutting on both sides of the paper guide wall provided oppositely or forming a part of one side of the paper guide path, which forms the insertion path continuing from the insertion port. An automatic paper feed roller for smoothly inserting and delivering paper is provided, and the feed rotation prevents the passage of paper and the like from staying on the curved surface of the paper guide wall, thereby facilitating delivery. In addition, since the paper guide walls are all curved and prevent insertion of the unsuitable material for cutting, even if the automatic paper feeding roller tries to send unsuitable material for cutting, the roller is idled and cannot be fed.
Needless to say, in the conventional shredder insertion path 20 as shown in FIG. 1, when the automatic paper feed roller is provided, it cannot be made impossible to feed.

The shredder insertion path is generally formed in the S-shape or the J-shape in order to prevent accidents in which the unsuitable materials for cutting, especially fingers, etc. are accidentally inserted and damaged, and the fingers are not delivered to the cutting cutter. By adopting a structure having an insertion path width dimension or an insertion path length dimension, it is possible to prevent insertion of an uncut object.
In addition, in the shredder insertion path, an automatic paper feed roller is arranged in the middle and the paper guide wall is forcibly fed, so that the paper guide wall is curved and prevents the insertion of the unsuitable material for cutting. By providing the automatic paper feed roller, it is possible to realize the performance of delivering papers and the like at the same level as the straight insertion path illustrated in FIG.

2 and 3 are views showing the configuration of the first embodiment of the shredder insertion path according to the present invention. In the figure, the paper insertion section path 21 extends in the elevation direction, forms a path width that does not allow a finger or the like to enter easily, and further forms a shape that prevents the first cutting inappropriate object such as a finger from passing through. is doing. This shape is formed and restricted by the opposing paper guide walls 21a and 21b. Each of the paper guide walls 21a and 21b has a curved surface that is generally S-shaped with a plurality of curves that are opposite to each other in the direction in which the paper guide walls swell, and the opposing paper guide walls are curved so as to maintain a constant interval. These intervals and the curved surface configuration prevent the finger 22 from reaching the cutting cutter 13, and the other finger 23 to be inserted from the opposite direction is similarly blocked at another portion of the curved surface.
Further, as shown in FIG. 3, the second unsuitable materials 24 and 25 such as a metal plate and a hard plate are blocked by the paper guide walls 21a and 21b regardless of whether they are inserted upright or obliquely. It is not delivered to the cutter 13.
Furthermore, when it is difficult to deliver paper or the like because it is generally S-shaped, an automatic paper feed roller 21c that rotates in the paper feed direction A is provided on one paper guide wall 21a as shown in FIG. The other paper guide wall 21b is provided with another automatic paper feed roller 21d that rotates in the paper feed direction B and is operated to smoothly deliver the paper. These automatic paper feed rollers may be disposed only on one of the paper guide walls 21a or 21b. Also, these automatic paper feed rollers achieve the desired performance by increasing the number according to the design conditions.
FIG. 5 is a view in which a paper guide wall, an automatic paper feed roller, and a cutting cutter are mounted. Reference numeral 2 denotes a part of a housing that includes them.

FIG. 6 shows the vertical direction shape of the second paper guide wall provided oppositely, in which the second shredder insertion path according to the present invention forms the paper insertion part path and the paper insertion part path. It shows that the cross-sectional shape shown is formed by a curve having the bulging direction in the same direction.
One second paper guide wall 26a is bent in a J-shape toward the second cutting cutter 13a, and the other second paper guide wall 26b is also bent in the same direction. The interval between the two second paper guide walls is an interval that prevents delivery of the first and second unsuitable materials while being suitable for insertion and delivery of paper or the like.
Due to these structures and shapes, the unsuitable insertion material is blocked by the second paper insertion path 22 and cannot be delivered to the second cutting cutter 13a. In addition, by providing the automatic paper feed roller on the second paper guide wall, it is possible to smoothly deliver the paper or the like.
FIG. 1 shows a conventional shredder insertion path, and a third paper insertion section path 20 is formed by a third paper guide wall 11a and another third paper guide wall 11b which are directed straight to the cutting cutter 13 and go straight. Since it is formed in a shape, it is impossible to prevent the insertion of the inappropriate insertion material.
