Description

[Detailed description of the invention] The present invention combines a mechanism for shredding confidential discarded documents and an opening mechanism for sealed items such as envelopes, and is lightweight and compact and has an opening mechanism that can be easily used on a tabletop. It is related to the cutting machine.

Conventionally, this type of document shredding machine has had to be large enough to be permanently installed in a fixed location due to its configuration, making it inconvenient to move or using it on a tabletop. It was also impossible. Furthermore, conventional machines were designed solely for shredding, and were not capable of dealing with desk-based office work, which has become particularly complex and fast in recent years.

In addition, some devices have been devised that have a simple opening mechanism, but the cutting blades of the opening mechanism are usually constructed so that they intersect with each other, similar to the cutting blades of the shredding mechanism. Since the envelopes and other items to be opened are manually fed, if the item to be opened is made of thin paper and the object is inserted too forcefully, the paper may get caught in the cross-section of the cutting blade. This puts a burden on the drive mechanism, which may reduce its lifespan and reliability.

In the present invention, the configuration of the device is simplified, and the device is made smaller and lighter in weight, making it suitable for tabletop placement and easy movement. It is an object of the present invention to provide a shredding machine that is fully adapted to modern office work that requires simplicity and speed, and is equipped with an opening mechanism that ensures safe and reliable operation without the risk of the blade biting and getting paper pieces caught when opening them. The purpose of

The second purpose is to shred the shredded material from two directions to reduce wasteful space in the storage case, since the size of the storage case for the shredded material is limited since it is for small tabletop use. The disadvantage is that the storage case quickly becomes full due to shredding in only one direction, which is the case with conventional small tabletop shredders of this type, and the shredded items must be disposed of each time. It solves the problem, and when pulled, it exhibits the perfect shredding effect on secret documents, etc.

The structure of the present invention is that the case has a shredded part insertion part, an opening for opening, and a removable shredded paper storage box, and the case has cutting blades arranged at regular intervals on the circumference. A vertical shredding mechanism consists of two rotary shredding rollers protruding from each other so that their respective cutting blades engage with each other, and a spiral shredding mechanism is provided behind the vertical shredding mechanism. A horizontal shredding mechanism consisting of a rotating roller having a plurality of blades, a fixed blade in contact with the rotating roller, a rotating blade with a sharp peripheral surface, and a rotating blade in contact with the cutting edge of the rotating blade. It consists of a blade receiving part having a blade receiving surface that cuts the sealing part by
The present invention relates to a shredding machine equipped with an unsealing mechanism in which a sealed part insertion part is opened to the outside other than the shredded object insertion part.

This will be explained as follows based on an embodiment shown in the drawings.

FIG. 1 is an external perspective view of the present invention, in which 1 is a shredding machine body equipped with an opening mechanism, and 2 is a shredded article storage that is removably fitted into the rear of the shredder body 1. It is a box and consists of a transparent case. 3 is a guide plate that guides objects to be shredded, such as documents and letters, to the shredding section; 4 is a rear part for inserting and melting into the opening mechanism; the opening mechanism is located below the opening 4;

Next, the internal mechanism will be explained based on FIGS. 2, 3, and 4. Reference numeral 5 in FIGS. 2 and 3 is a vertical shredding mechanism, in which two rotating rolls 5a and 5b come into rotational contact and cut the material on the guide plate 3 in the vertical direction. Book rotating roller 5
A and 5b each have cutting blades 5 at regular intervals.
a' and 5b' are provided in a protruding manner, and these cutting blades 5a' and 5b' are arranged oppositely so as to mesh with each other. Reference numeral 6 denotes a horizontal shredding mechanism located behind the vertical shredding mechanism 5, which shreds the material cut into multiple pieces by the vertical shredding mechanism 5 and sent out. It is meant to be shredded. Its structure consists of a rotating member 6 having a plurality of spiral cutting blades 6a protruding from its circumferential surface.
b, and a fixed blade 7 that contacts the cutting blade 6a of the rotating member 6b. Reference numeral 8 denotes an unsealing mechanism, in which two rotating members are brought into rotational contact, the peripheral surface of one of the rotating members 8a having a sharp cutting edge, and the cutting edge of the rotating member 8a making contact (contact) with the other rotating member 8b. ) As the blade receiving surface has a blade receiving surface, the engagement (crossing) of the cutting edge makes it easy for pieces of paper etc. to get caught due to loosening of the engagement of the blade due to long-term use.
This method does not cut by pressing the cutting edge against the surface. 9a and 9b are members for scraping off when paper pieces are clogged in the recesses other than the protruding parts of the cutting blades 5a' and 5b' of the rotating rolls 5a and 5b of the vertical shredding mechanism 5; 9a is located in a recess in the rotating roll 5a, and the other scraping member 9b also serves as the guide plate 3 and is located in the recess in the rotating roll 5b in the same way as the scraping member 9a described above to perform the scraping action. It is something that demonstrates the.

Furthermore, the driving state of this internal mechanism is determined by the motor 10.
Gears 11, 12, 13, 14, 15 are activated by the operation of
and a rotary roll 5 for longitudinal shredding via 16
b, 5a, and as shown in FIG. 4, the gear 20 is rotationally driven via the gears 12, 13, 14, and the horizontal shredding rotary member 6b is also rotationally driven. In addition, gears 18 and 19 are driven via the FES gear 17, and rotating members 8a and 8b for the opening mechanism 8 are driven.
It also rotates. Reference numeral 13 denotes legs for preventing slipping when the shredding machine is placed on a tabletop.

Next, an example of a usage state of a shredding machine equipped with the opening mechanism of the present invention having the above configuration will be described.

One side part of the sealed envelope is first inserted into the opening mechanism 8, and the sealed part is opened to make it easy to take out the contents. After looking through the contents of documents, letters, etc., if you think it is appropriate to shred the contents, insert the contents or opened envelopes into the main body 1 from the shredding guide plate 3. When inserted, it is first shredded by the vertical shredding mechanism 5,
The sent out shredded material is then shredded by a lateral shredding mechanism 6, and the shredded objects fall into small pieces into the shredded material storage box 2 and are stacked. When the shredded items are stored to the full capacity of the shredded storage box 2, remove and discard them, and return to the main body 1.
Insert and attach.

However, the shredding machine equipped with the opening mechanism of the present invention has an extremely convenient configuration for opening and shredding envelopes, small documents, etc. on a tabletop, and the shredding can be done by hand, scissors, etc. Opening operations can be carried out with peace of mind without the risk of damaging the contents, and there is no risk of chewing on pieces of paper such as envelopes and putting a strain on the drive system when opening them. Moreover, since the shredding machine according to the present invention is for small desktop use, it is necessary to reduce the size of the shredded material storage box. Therefore, the items to be shredded are shredded vertically and horizontally to create extremely small pieces of paper, reducing the amount of space left in the shredded item storage box, making it possible to store them very efficiently. Not only that, but it also satisfies the primary purpose of shredding confidential documents into as small pieces as possible when disposing of them.

According to the present invention, which exhibits the various effects described above, the efficiency of desk-top office processing can be further improved.
