DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste paper processing apparatus,
The progress of the crushing can be visually confirmed.

[0002]

2. Description of the Related Art Used paper used in offices is discarded or recycled. In order to dispose or recycle the waste paper, it is necessary to crush the waste paper, and a waste paper processing device is used for that purpose.

[0003] Shredders have conventionally been used as used paper processing equipment. The main purpose of the shredder is to keep the information written on the used paper confidential.
Cut into small pieces of about 3 mm. For this reason, the fiber of paper is cut finely, and the crushed paper piece cannot be used as a raw material of recycled paper.

[0004] For this reason, there is a processing apparatus which does not cut the fiber of paper as shown in FIGS. 3 (a) and 3 (b). As shown in the figure, a pair of rotating shafts 1 and 2 extending in the horizontal direction are accommodated in the frame 6 in a state where they are arranged in parallel on a horizontal plane,
A plurality of rotary blades 3 and 4 are fixed to each rotary shaft 1 and 2 at equal intervals. The rotary blades 3 and 4 are provided so as to be alternately arranged in the axial direction, and so that the rotary blades 3 and the rotary blades 4 partially overlap each other when viewed from the axial direction.

[0005] All of the used waste paper is directly
In order to prevent the paper from moving downward from outside and being caught in the biting portion 5, fixed quantity feeding members 7 for feeding used paper by a fixed amount are arranged between every two adjacent rotary blades 3, 4.
It is connected to the frame 6 via bolts 8. The fixed-rate feed member 7 has a stopper portion that gradually reduces the interval between the blades of the rotary blades 3 and 4 when projected onto a plane perpendicular to the rotary shafts 1 and 2 along the rotation direction of the rotary blades 3 and 4. Round bar 9
a, 9b, and 9c are fixed to the fixed-quantity feeding member 7 in a state where their axes are orthogonal to the rotation shafts 1 and 2. Further, between the round bar 9c and the rotary blades 3 and 4, a fixed amount gap G that determines the amount of used paper fed is set.

[0006] When the used paper is crushed by the rotary blades 3 and 4,
Since the crushed waste paper is wrapped around the rotating shafts 1 and 2 and cannot be removed, the wrap preventing ring 1 is disposed between the adjacent rotating blades 3 and 4.
0 is provided.

[0007] Waste paper is fed from the upper part of the frame 6, and the structure of the loading port is as shown in Fig. 4 (a), the loading port 6a configured to feed the waste paper 11 vertically downward, As shown in FIG. 4 (b), an input port 6c or the like configured to input the waste paper 11 by horizontally moving it along the input table 6b or placing it on the input table 6b and pushing it out in the horizontal direction is conceivable. However, in the configuration shown in FIG. 4A, when an object other than used paper that does not need to be excerpted by mistake is dropped on the used paper processing device, the rotary blades 3 and 4 pass through the inlet 6a. 4B may be dropped to the top, and therefore, the structure shown in FIG.

Next, the operation of the used paper processing apparatus will be described.

In order to improve the efficiency of biting used paper,
As shown by changing the length of the arrow in FIG. 3B, the rotation speed of the rotary shaft 2 is set to be lower than that of the rotary shaft 1, and the waste paper enters the space between the rotary blade 4 and the fixed-rate feeding member 7. It is set as follows. While rotating the rotating blades 3 and 4 in the directions opposite to each other as shown by the arrows in FIG. 3B, when the used paper is put into the frame 6 from the input port 6c shown in FIG. It is mainly caught by the rotating blade 4 having a small number of rotations, turns downward from the outside of the rotating blade 4, moves to the engaging portion 5, and is crushed by the engaging portion 5 so as to be torn. Once the waste paper has entered between the fixed amount feeding member 7 and the rotary blade 4, the leading end of the waste paper of a certain amount or more hits the round bars 9a and 9b, so that the feeding of the waste paper is suppressed. The used paper is stopped by the round bars 9a, 9b and 9c in order from the one farthest from the rotary blade 4 and is sent in order from the closest one. Since it is set, a large amount of waste paper is not simultaneously sent to the biting portion 5 and is not overloaded.

[0010] When the paper is crushed and elongated, the waste paper is turned on the rotating shaft 1,
Although it may not be able to be wrapped around and become unremovable, and may eventually become a large load on the rotational force, a winding prevention ring 10 is provided between the adjacent rotary blades 3 and 4 so that the rotary shafts 1 and 2 are exposed. As a result, the winding of the used paper around the rotating shafts 1 and 2 is prevented.

[0011]

However, as shown in FIG. 5, the used paper on the loading table 6b is made of round bars 9a, 9
b, 9c, the waste paper 11 on the rotary blade 4 side
The leading edge of the waste paper comes first, and the waste paper on the side of the rotary blade 4 is sequentially pulled by the rotary blade 4, and the waste paper on the side of the anti-rotation blade 4 is finally crushed. Waste paper on the submission stage. 6b times
Since it is pulled in from the bottom by the rolling blade 4 and is torn off, there is a problem that it is difficult for an operator who puts in the used paper to visually confirm the progress of the crushing process.

It is an object of the present invention to solve the above-mentioned problem and to provide a waste paper processing apparatus capable of checking the progress of crushing by being sequentially drawn in from the upper waste paper.

[0013]

In order to achieve the above object, the present invention has a structure in which rotary blades are fixed to a pair of rotary shafts which are arranged substantially in parallel on a horizontal plane and are driven in mutually opposite directions. In a waste paper processing apparatus set so as to bite waste paper inserted from above the rotary blade from below, a loading table for placing the waste paper substantially horizontally is provided above one of the rotating shafts, and is inserted. A guide is provided which guides the used paper on the table in a substantially U-shape and guides the used paper from above between the pair of rotation shafts to above the one rotation shaft, and a fixed- rate feeding member is provided above the one rotation shaft.
And fix the tip of the fixed amount feeding member.
Protrude in the horizontal direction to form a protrusion, and
Below the protruding part of the material, there is a slide that controls the movement of waste paper.
A topper portion is formed .

[0014]

In the waste paper processing apparatus according to the first aspect, when the waste paper is placed on the loading table and fed little by little from the end, the waste paper is bent in a U-shape along the guide and is the outermost one near the rotary blade. It is sent in order from. That is, the waste paper is fed in order from the upper part on the input table, and the operator can visually confirm the progress of the crushing.

More specifically, the used paper is bent in a U-shape along the arc surface of the leading end of the fixed amount feeding member and fed in, and the leading end of the succeeding outer used paper is flipped up by the rotary blade to collide with the used paper. The leading end of the inner waste paper is caught by the stopper portion, and the succeeding waste paper is similarly flipped up the leading end of the preceding waste paper and caught by the stopper portion. For this reason, crushing is performed in order from the outermost, that is, the uppermost waste paper on the input table.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. In this embodiment, since a part of the conventional used paper processing apparatus is improved, the same parts as those in the related art are denoted by the same reference numerals, and description thereof will be omitted. Only different parts will be described.

FIG. 1 shows the configuration of a used paper processing apparatus according to the present invention. As shown in the figure, a fixed-rate feed member 7 is provided above the rotary blade 4 having a low rotation speed. In the present invention, the tip of the fixed-rate feed member 7 protrudes leftward from the position of the round bar 9a. The portion 7a is formed. An arc surface 7b is formed on the outer peripheral surface of the protruding portion 7a.

Above the fixed amount feeding member 7, a loading table 6b for placing the used paper 11 is fixedly provided on the frame 6, and the used paper 11 on the loading table 6b is moved between the fixed amount feeding member 7 and the rotary blade 4. A guide 6d is provided for guiding the feed port, and an input port 6c is formed between the input table 6b and the guide 6d. The loading table 6b is disposed above the fixed amount feeding member 7 because the lower waste paper 11 in a state where the loading table 6b is placed on the loading table 6b.
Is to enter between the fixed-rate feeding member 7 and the rotary blade 4 having a low rotation speed before the upper portion.

The reason why the protruding portion 7a is provided as described above is as follows. As shown in FIG. 2A, the used paper 11 is substantially U
When the waste paper 11 is turned around the rotary blade 4 and moves to the biting portion 5 when the used paper 11 is set so as to be bent and fed, the upper one is caught by the rotary blade 4 on the loading table 6b and the other. However, the waste paper 11 located on the lower side of the input table 6b is bent into an arc shape having a smaller radius dimension than that located on the upper side, so that the leading end of the waste paper 11 has another end. May precede the
As shown in (b), the used paper 11 on the anti-rotation blade 4 side is a round bar 9a.
When the used paper 11 on the side of the rotary blade 4 passes through the round bar 9a after passing through, the dozens of used papers rotate with the fixed amount feeding member 7 without the effect of suppressing the end of the used paper by the round bar 9a. It is bitten at the same time with the blade 4 and becomes overloaded. On the other hand, when the protruding portion 7a is formed, the leading end of the succeeding waste paper is flipped up by the rotary blade 4 to flip up the leading end of the preceding waste paper, and the waste paper at a position away from the rotary blade 4 is round bars 9a, 9
This is because the movement is restrained by b and 9c, and the paper is always fed in order from the waste paper close to the rotary blade 4.

Next, the operation of the used paper processing apparatus will be described. The rotating blades 3 and 4 are rotated in opposite directions, and the number of rotations of the rotating blade 4 is made lower than that of the rotating blade 3. Rotary blade 3
The reason why the rotating speed of the rotary blade 4 is made lower than that is that the waste paper formed into a band by crushing is peeled off from the rotating blade 3 having a high rotating speed by the rotating blade 4 having a low rotating speed, and the band-shaped waste paper is It is to move around. When the used paper 11 is placed on the loading table 6b and pushed out to the left little by little, the leading end of the used paper 11 is guided by the guide 6d and enters the space between the fixed amount feeding member 7 and the rotary blade 4 having a low rotation speed. At this time, the leading end of the lower waste paper 11 arrives at the rotary blade 4 in advance on the loading stand 6b, which is waste paper located at a position having a small radius of curvature. Then, when the waste paper 11 above the lower waste paper 11 reaches the rotary blade 4 after the lower waste paper 11, the leading end of the succeeding waste paper 11 is flipped upward by the rotary blade 4 at the point A in FIG. For this reason, the leading end of the preceding used paper 11 is flipped up by the leading end of the succeeding used paper 11 and hits the round bar 9a as indicated by B in FIG. 1B, and the feeding of the lower used paper 11 is suppressed.

Thereafter, the upper ones of the used papers 11 on the loading table 6b arrive at the rotary blade 4 in sequence, but as long as the used paper 11 that subsequently arrives at the rotary blade 4 exists, the round bar 9 is used.
In front of "a", it is flipped up and hits the round bar 9a, so that feeding is suppressed. When the subsequent waste paper 11 runs out, the outer waste paper 11 located at the position having the largest radius of curvature is hooked by the rotary blade 4 in order, passes through the round bar 9a, and moves to the round bar 9b. Also in this case, since the leading end of the used paper 11 is flipped up by the rotary blade 4, the used paper moves to the round bar 9c in order from the outer used paper in the same manner as the round bar 9a. Then, it moves to the biting portion 5 through the outside of the rotary blade 4 in order from the outside of the used paper 11 arriving here.

In other words, the input table 6
b. The used paper 11 placed on the b
a, 9b, 9c, and is fed into the biting portion 5. For this reason, the worker who puts the used paper can visually confirm the degree of crushing progress.

In addition, instead of providing a round bar as a stopper, the fixed-quantity feeding member may be directly formed in a stepped or saw-tooth shape.

[0024]

As can be seen from the above description, claim 1
According to the used paper processing apparatus according to the above, since the used paper is bent into a substantially U-shape and fed from the loading table, the waste paper is fed in order from the upper portion of the loading table, and the worker who inputs the recovered paper requires a crushing process. The degree can be confirmed visually.

That is, since a fixed-quantity feeding member having a stopper portion is provided above one of the rotation shafts and the tip thereof is projected in the horizontal direction, the waste paper fed into the U-shape bent substantially U-shape. The tip of the inner one is flipped up by the tip of the succeeding outer waste paper in order and is suppressed by the stopper ,
The bent outer waste paper, that is, the waste paper on the upper side of the loading table will be sent sequentially and crushed, and the operator who throws in the waste paper can visually check the progress of the crushing , feeling pyotropic I don't feel tired or tired.
