ない新規な文書処理装置を提供することにある。However, in recent years, there has been an increasing movement to promote the reuse of used paper due to environmental problems, resource problems, etc., and attention has been paid to the use of recycled paper. In the shredded waste paper, there is a problem that the fibers are fined by cutting the paper fibers, and the production yield of waste pulp from these shredded waste papers is reduced. Further, since the cutting direction of a waste document shredded in a dry state is constant, it is relatively easy to restore a state in which a shredded paper piece, particularly a strip-shaped shredded paper piece, to a state before shredding, and the waste document Was also an inevitable problem. Also, since the shredded paper pieces cut into such a band shape are bulkier and bulkier than the state of the documents before shredding, the storage of the shredded paper waste is much more than before shredding. There is also a problem that a large space is required and that it takes time to carry out processing such as transportation of the shredded paper pieces. Accordingly, an object of the present invention is to provide a novel document processing apparatus which is improved in the above-mentioned drawbacks of the prior art, is excellent in waste paper pulp production yield and secret leakage prevention properties, and has no bulky waste disposal documents. is there.

The production yield of waste paper pulp from documents can be increased. Further, since the document is defibrated underwater so that it cannot be restored, the risk of secret leakage from the discarded document is reduced. Further, the space for storing the waste after the disposal can be reduced, and processing such as transportation of the waste can be facilitated.

FIG. 1 is a cross-sectional view of the entire document processing apparatus according to the present invention, and FIG. 2 is a top view thereof.
1 in FIG. 1 is a casing of the document processing apparatus of the present invention,
Reference numerals 2a, 2b, and 2c denote outer walls of the water tank, and 2c also serves as an outer wall of the screw conveyor transport unit. First, the waste document paper put into the water tank absorbs water in water and swells. Next, the paper containing the water enters through a screw conveyer conveyance unit entrance 5 (shown in FIG. 2) in the water tank, and is conveyed obliquely upward by the rotating screw conveyer 4. At this time, the stirring and rotation of the screw blades of the screw conveyor 4 in the water tank, and the screw blades and the outer wall 2
Due to the friction between c and c, the waste document is partially "torn" and "fibrillated". The waste document paper thus transported arrives along with the water along the screw conveyor transport unit to reach the water removal unit 6 located above the screw conveyor transport unit, and the water contained in the waste document paper is removed by the water removal unit hole 6 ′. More drained. At this time, in order to efficiently squeeze only water from the suspension of the waste paper and water and drain the water from the water removing portion hole 6 ′, the pitch width of the screw conveyor 4 must be adjusted as shown in FIG. It becomes narrower (l 1 > l 2 ) toward the upper part, a fine hole is formed in the teeth of the screw conveyor in the axial direction of the screw conveyor (not shown), or the water removal part hole 6 ′ It is preferable to provide means such as providing a fine net (not shown).

The rotating body 11 in the defibrating unit 10 is coaxial with the screw conveyor 4 as shown in FIG. 3, and has a plurality of guide grooves 20 and teeth 21, and has a cone shape as shown in FIG. It is configured to engage with a housing 7 having an inner wall. In addition, as shown in FIG.
Is from the small diameter portion to the large diameter portion, h 1 > h 2 > 0
Further, the width of the guide groove 20 is a sector (extended end) such that W 2 > W 1 > 0 from the small diameter portion to the large diameter portion. Similarly, a plurality of teeth 22 are provided on the cone-shaped inner wall of the housing 7 as shown in FIG. 4, and a guide groove 23 is formed near the teeth 22. Each of these guide grooves 23 is
It is formed so as to become gradually deeper in the radial cross section toward the tooth portion 22 and to be tapered in the axial direction.

る。In the defibrating unit 10 having the above-described structure, the waste paper fed to the defibrating unit 10 by the screw conveyor 4 is first sent to the spaces of the grooves 20 and 23, Is rotated by the teeth 21 and 22 during the rotation of. During this time, the waste document paper and the defibrated material collide with the groove 23 due to centrifugal force and move inside the groove 23 in a diagonally upper left direction in FIG. 1 (left direction in FIG. 2). At this time, since the depth of the groove 23 is reduced along the axial direction,
The waste paper and its defibrated material are gradually fined as it moves in the axial direction. In the defibrating unit 10 , a function (action) of squeezing water out of the defibrated material is simultaneously performed, and the squeezed water is drained from the water removing unit hole 6 ′ of the water removing unit 6. The waste paper thus defibrated is shown in FIG.
After passing through the space 13 between the rotating body 12 and the housing 9 of the document processing apparatus, it is stored in the lower part of the document processing apparatus from the discharge cylinder 15 through the outlet passage 14. The discarded paper thus discarded is used as a raw material for waste paper pulp.

I can do it. In addition, since the waste documents are swollen and processed in water, the risk of secret leakage can be reduced as in the case of processing by the dry method, and the bulk of the paper after the waste processing is reduced. effective.
