Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unnecessary sheet-like object to be cut (hereinafter referred to as waste paper, film, tape, etc.).
The present invention relates to a shredder provided with a space for cutting a cutting object) with a cutter and accommodating cutting waste generated by the cutting under the cutter.

[0002]

2. Description of the Related Art Unnecessary cuts as described above are usually
Although it is cut by the cutter in the shredder, a large amount of cutting waste is generated by cutting, so it is temporarily collected in the large-capacity storage box located below the cutter, and every time the cutting waste becomes full, or periodically. The storage box is removed, and only the internal cutting waste is disposed.

Every time cutting is performed in the shredder housing, cutting scraps represented by paper scraps and paper dusts are generated, and when the cutting scraps are accumulated in the shredder to some extent, the above-mentioned cutting scraps taking-out method is adopted. In the shredder,
Light cutting debris may fly up in the air flow that occurs when the storage box is removed. In addition, the lumps of cutting waste that have adhered to the cutter or the like and accumulated may sometimes fall naturally on the bottom plate of the shredder.

Therefore, in the above-mentioned shredder, cutting debris sometimes scatters on the floor inside and outside the shredder when the storage box is taken out. Therefore, not only is the storage box taken out and the cutting debris inside is discarded. In addition, the work of collecting scattered cutting scraps and cleaning the surrounding area is also added, and the actual situation is that the disposal work is extremely troublesome. Therefore, various efforts have been made to solve this problem.

For example, in the paper piece processing apparatus described in Japanese Patent Laid-Open No. 05-24647, a paper piece processing apparatus, which has been cut and removed from a continuous paper, is moved from the continuous paper processing apparatus to another place. Cut into short pieces and compress it, and in order to dispose of the compressed paper pieces without scattering paper dust, etc., the paper pieces such as the marginal part received by the suction hood are sucked into the shred blower and cut into short pieces. The paper pieces that have been cut into pieces and led to a cyclone and separated from the air and paper dust are dropped into a compression box and sequentially compressed by a compression ram, and when a predetermined amount is accumulated, they are discharged.
The air and paper dust separated from the paper pieces by the above-mentioned cyclone are introduced into a dust collector, the paper dust is removed by a filter, and the cleaned air is exhausted from the exhaust stack.

Further, in Japanese Patent Laid-Open No. 09-168749, "Shredder", it is possible to prevent dust from scattering outside the waste container box during operation of the shredder and to prevent spillage, and to prevent spillage of trash and trash when taking out the waste container box. In order to prevent this, a shredder is disclosed which is provided with a mechanism capable of raising and lowering a waste storage box and fixing the position in both the ascending and descending states. That is, when cutting, the storage box is raised to a position close to the cutting machine, and when taking out, the partition plate is lowered to a position away from the cutting machine.

Further, the invention described in Japanese Unexamined Patent Publication No. 09-141117, "Shredder scrap receiving plate" is provided with a shredding machine at the uppermost stage of a drawer type cabinet composed of a frame, and directly below the shredding machine. In a shredder with a drawer as a waste box, shredder scrapes that inevitably fly as the waste box is taken in and out are prevented from falling onto the floor and the storage box at the next stage of the waste box, and the shredded scrap that has spilled out. The purpose of the present invention is to provide a scrap catching plate that can be easily collected and cleaned. This scrap catching plate has a flat plate removably placed on the edge of the horizontal frame of the frame and the center of the horizontal frame is removed. The open part of is closed. Specifically, in the scrap receiving plate, a flat plate for closing the opening formed in the center is detachably placed on the horizontal frame edge of the frame, and the flat plate and the bottom plate of the scrap box are placed between the flat plate and the scrap receiving plate. To form a space portion, more specifically, the flat plate is a flat plate having a recess for fitting into an opening formed in the center of the horizontal frame of the frame, or
A flat plate with parallel ridges on the upper surface of the flat plate in the direction of drawing out the waste box is used.

[0008]

However, Japanese Patent Laid-Open No. 05-24647 and Japanese Patent Laid-Open No. 09-168749.
According to the technique described in Japanese Patent Publication No. JP-A-05-205, since a device becomes large because a special mechanism is required to be installed, which inevitably results in a high manufacturing cost, a model aiming at small size and low price. 24647 and Japanese Patent Laid-Open No. 09-16874.
It is not realistic to apply the technique of Japanese Patent No. 9 publication. Further, the technique described in Japanese Patent Laid-Open No. 09-141117 is
Although the cutting scraps can be prevented from flowing out by the action of the scrap receiving plate, it is necessary to take out the scrap receiving plate and discard the cutting scraps.

The present invention has been made in view of the above circumstances, and realizes a technique which can be applied to a shredder aiming at downsizing and low price while preventing scattering and outflow to the outside due to rising of cutting dust. With the goal.

It is another object of the present invention to provide a technique capable of preventing the cutting dust remaining on the cutter and attached to the shredder from dropping on the shredder bottom plate.

An opening (bag passage) is formed in the lower half portion of the front plate 2b, and the door 3 is provided at the upper end portion of the door 3 in the upper half portion of the front plate 2b by a known means so that the opening can be selectively opened and closed. It is supported.

The upper part of the inner space of the housing 2 is an installation space for the cutting machine or the cutter 4, and the lower part is for accommodating cutting waste 4a falling from the cutter 4 or the like during operation. It serves as a storage space for the storage container (bag-shaped body) 7, and between the upper part and the lower part,
It is a collecting space for the cutting waste 4a, and a collecting means described later is installed therein.

In this embodiment, mortar-shaped waste receivers 5 and 6 (collecting means) which are inclined downward toward the center are provided in two stages in the above-mentioned storage space and are vertically spaced apart from each other. There is. Each of the scrap receivers 5 and 6 has an opening 5a and 6a in the center, and the diameter thereof is the upper scrap receiver 5a.
The opening 5a is larger than the opening 6a of the lower scrap receiver 6. The opening 6 a of the lower scrap receiver 6 is smaller than the opening in the upper portion of the storage container 7. Therefore, most of the cutting dust 4a falling from the cutter 4 may enter the container 7, and some of the scattered cutting dust and paper dust may be collected on the upper and lower waste receivers 5 and 6. If it falls, it will surely enter the container 7.

The door 3 is suspended from the upper half of the front plate 2b as shown in FIG. 1 when the opening (bag passage) 9 formed in the front plate 2b is closed. ,

As a result, a partition wall is formed between the cutter 4 and the storage container 7, so that after the storage container 7 is taken out of the housing 2, the cutting debris 4a may fall into the space where the storage container 7 was scattered. Disappears.

Next, the bag setting device 8 is removed from the lower waste container 6, and the container 7 together with the bag setting device 8 is taken out of the housing 2. After that, if the bag installing device 8 is removed from the taken-out container 7 in the reverse order of the above, the cutting waste can be discarded together with the container 7. Needless to say, the container 7 may be repeatedly used without being discarded.

In the preferred embodiment described above, the upper and lower debris receivers 5, 6 which make up the collecting means are tilted at substantially the same angle, but the tilt angles may be different.
In this case, when the door 3 is in the open state, the inclination angle of the upper scrap receiver 5 is made larger than that of the lower scrap receiver 6 so that the cutting scrap does not drop on the door 3, and the door 3 is opened. It is preferable to drop the cutting scraps accumulated on the scrap receiver 5 at the upper part before reaching. Also, in the embodiment, the upper scrap receiver 5
Was provided, but this may be omitted. Furthermore, if the bag setting device 8 can be magnetically coupled to the lower waste container 6,
It may consist of only a ring. In this case, in order to mount the bag-shaped body 7, the opening edge portion is put inside the ring and then folded back to the outside, and then the ring is placed on the scrap receiver 6 at the bottom.
Magnetically coupled to.
