DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration of a specific embodiment of the present invention will be described with reference to the accompanying drawings.

1 to 4, a cutter 10 for a document separator according to an embodiment of the present invention is included in a three-dimensional member 30 provided inside the body 20 of the document separator 100.

The document separator 100 includes a main body 20 having a mouth 21 through which a document 1 is inserted on a top surface thereof and a door 22 opened and closed at a side thereof, A collection container 40 for collecting a document 1 which is installed in the main body 20 and is cut out from the three-dimensional member 30; .

The main body 20 further includes a sensor for recognizing the document 1 to be inserted into the input port 21 and a controller for operating the cradle member 30 by receiving a signal transmitted from the sensor.

The three-dimensional member 30 includes a pair of support rods 31 fixedly installed at a predetermined distance in the main body 20 and two support rods 31 provided between the support rods 31, First and second rotating shafts 32 and 33 and first and second gears 32a and 33a coupled to one ends of the first and second rotating shafts 32 and 33, And a driving motor 34 having a first driving gear 32b coupled to the other end of the first driving gear 32 and a second driving gear 34a connected to the first driving gear 32b by a belt or a chain .

Here, the first and second gears 32a and 33a are connected to mesh with each other.

The three-dimensional member 30 includes a cutter 10 for a document separator which is assembled to the first and second rotary shafts 32 and 33 at regular intervals, A spacing plate 35 assembled to the two rotary shafts 32 and 33 and a fixing rod 36 fixed to the supporting rods 31 through the spacing plates 34.

The cutter 10 for each document assembler and the cutter 10 for each document assembler assembled to the second rotary shaft 33 assembled to the first rotary shaft 32 are arranged so as to intersect with each other .

Each of the spacing plates 35 maintains the spacing of the cutter 10 for each document separator even if the first and second rotating shafts 32 and 33 rotate. 32) 33 are rotated, the respective spacing plates 35 are prevented from moving.

The cutter for a document separating machine 10 includes a body 11 having a circular plate shape and formed with a shaft insertion hole 11a through which a first rotation shaft 32 or a second rotation shaft 33 is inserted, And a cradle blade 12 protruding radially from the edge of the body 11 with respect to the shaft insertion hole 11a.

A concave groove 13 is formed so as to be inclined at one corner of the edge of the body 11 and the edge face of the cradle blade 12 so that both ends A of the groove 13 are connected to each other. (B) is formed sharply.

An angle between the end B of the groove 13 at the farthest position from the shaft insertion hole 11a and the end A of the groove 13 nearest to the shaft insertion hole 11a ([theta]) is formed at 16 [deg.].

The operation and effect of the embodiment of the present invention will be described below.

As shown in FIGS. 1 to 4, when a plurality of documents 1 are inserted into the input port 21 of the document separator 100, the sensor recognizes the same and transmits a signal to the controller, And operates the driving motor 34 of the cradle member 30. [

Then, the first and second driving gears 32b and 34a connected to the belt or the chain are rotated by the operation of the driving motor 34, and at the same time, the first rotating shaft 32 rotates.

The first and second gears 32a and 33a engaged by the rotation of the first rotation shaft 32 rotate and the second rotation shaft 33 coupled with the second gear 33a .

That is, the cutter 10 for the document separator assembled to the first and second rotary shafts 32 and 33 rotates in directions opposite to each other.

Therefore, when a plurality of documents 1 are inserted between the cutter for document shredders 10 facing each other, the document 1 is in point contact with both ends A and B of the groove 13, (13).

Since the both ends A and B of the groove 13 are formed by the grooves 13 in a sharp manner, the document 1 is formed on the both ends A and B of the groove 13, So that the movement is limited more easily than in the prior art.

Since the groove 13 is formed continuously from the rim surface of the body 11 and the rim surface of the caterpillar 12 so that the caterpillar for the document 1 to be dismounted is formed on the rim of the caterpillar 12, (A) and (B) of the groove 13 formed on the edge face of the body 11 as well as both ends A and B of the groove 13 formed on the body 11.

That is, the document 1 can be trimmed with the entire edge surface of the cutter 10 for a document separator.

In other words. The document 1 to be discarded is faded by the saddle force of the cutter 10 for the document separator which is increased more than the conventional one.

Therefore, even if a large number of documents 1, which are larger than the conventional ones, are fed into the loading port 21 of the document separator 100, the stronger sedan of the separator 10 for the document separator facilitates the document 1).

In addition, since the load applied to the first and second rotary shafts 32 and 33 of the document shredder 100 according to the input of a large number of the documents 1 at a time is reduced, the vibration of the drive motor 34 is reduced The noise and vibration generated during the operation of the document 1 to be discarded as a sedan by point contact on both ends A and B of the groove 13 as well as the surface contact can be remarkably reduced.

When the document 1, that is, the chip, which is cut in the groove 13 having an angle θ of 16 ° between the both ends A and B is received in a compressed state, , The chip easily escapes from the groove 13 and is collected in the collection container 40 as shown in Fig.

The discarded document 1 collected in the collection container 40 can then be emptied from the collection container 40 through the door 22 of the document separator 100.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Various changes and modifications may be made by those skilled in the art.
