Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for separating waste paper and binding strings.

[Prior art and its problems]

When recycled paper such as old newspapers and magazines is recycled at a used paper recycling factory, a particular problem is the vinyl or other strings that bind the used paper, and conventionally, they have to be removed manually before the recycling process begins. , removed by mechanical force during the regeneration process.

However, the method of manually removing the strings requires a huge amount of time and effort, and the method of removing the strings during the recycling process results in a decrease in the quality of recycled paper due to incomplete removal of the strings. there was.

An object of the present invention is to provide an apparatus for separating used paper and binding strings, which can easily and reliably separate the used paper and the strings binding the same with high efficiency.

A waste paper discharge port is provided in the center, and a string discharge port is provided downstream of the waste paper discharge port in the direction of movement of the waste paper, and the loose bundle means includes a horizontal first rotating shaft provided within the fixed drum; A pair of flanges fixed to the pair of first rotating shafts at a distance, and a plurality of chains twisted in the circumferential direction and stretched parallel to each other between the flanges, The bundling means includes a horizontal second rotating shaft provided in the rotating drum, and a plurality of unbundling blades attached at intervals to the outer surface of the second rotating shaft, and the repairing means includes: The discharging means comprises a plurality of bottles radially attached to the rotating drum at intervals along the circumferential direction of the rotating drum so that they can be freely moved in and out by their own weight, and the discharging means includes:
The present invention is characterized in that it includes a blade attached to the second rotation shaft for generating wind flowing in the direction of the paper discharge port of the rotary drum.

Next, one embodiment of the sorting device of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the sorting device of the present invention.

As shown in FIG. 1, the sorting device of the present invention includes a loosening means A for loosening the binding strings of used paper, and an unbundling means for separating the strings loosened by the loosening means A from the waste paper. B, a collecting means C for collecting the strings detached by the unbundling means B, a discharging means for discharging the strings collected by the collecting means C from the rotating drum, which will be described later; Fixed drum E for accommodating east means A and unbundling means B
, a rotating drum F for accommodating a collecting means C5 and a discharging means.

The fixed drum E has a hopper 1 for inputting waste paper at the upper part,
It is fixed horizontally on a pedestal 2.

The rotary drum F has a receiver provided on a pedestal 2 placed horizontally on a roller 3, and is rotatably connected to a fixed drum E. A sprocket 4 is fixed to the outer peripheral surface of the rotating drum F, and the tin rocket 4 is attached to a chain 5.
It is rotated by the motor 6 via the. The rotating drum F is
It has a plurality of slanted scrape puffs for sequentially transporting the used paper sent from the fixed drum E toward the used paper outlet 8, which will be described later. A string discharge port 9 is provided on the downstream side in the direction of waste paper movement.

The loose bundle means A comprises a horizontal first
A rotating shaft 10, a pair of flanges 11 identified at intervals on the first rotating shaft 10, and a plurality of flanges 11 twisted in the circumferential direction and stretched parallel to each other between the outer edges of the pair of flanges 11. It consists of a chain 12. The first rotating shaft 10 is rotated by a motor 13.

The unbundling means B is a horizontal second
It consists of a rotating shaft 14 and a plurality of unbundling blades 15 attached to the outer surface of the second rotating shaft 14 at intervals. The unbundling blade 15 is made of a metal ring that is partially cut off and has a gap S, and as shown in FIG.
The mounting fixed to the outer surface of the metal fitting 16 is movably fitted into the metal fitting 16. The second rotating shaft 14 is connected to the first rotating shaft 10 via a chain 17.

As shown in FIG. 3, the collecting means C consists of a plurality of pins 1B radially attached to the rotating drum F at intervals along its circumferential direction.

The pin 18 is loosely fitted into a hole 19 formed in the rotating drum F, and freely moves in and out of the rotating drum F due to its own weight. Both ends of the pin 80 are formed to be larger than the diameter of the hole 19 so that the pin 80 does not come out from the rotating drum F.

The discharge means is composed of a plurality of blades 20 attached to the downstream end of the second rotating shaft 14 in the direction of movement of the used paper. The blades 20 generate wind that flows in the direction of the string outlet 9 of the rotating drum F.

[Effect]

When waste paper bound with strings is thrown into the fixed drum F from the hopper 1, the waste paper collides with the chain 12 of the rotating loose bundling means A. This prevents the waste paper from falling apart and loosens the strings that hold it together. Since the waste paper whose string has become loose in this way is twisted and stretched around the rotating chain 12, it gradually moves toward the rotating drum F side. The waste paper transferred into the rotating drum F is gradually transferred in the direction of the waste paper discharge port 8 by the scraper 7, and in this process, the binding string is moved by the unbundling blade of the unbundling means B, which rotates in conjunction with the loosening means A. It enters the gap S of 15, is cut, and is separated from the waste paper. At this time, since the unbundling blade 15 is ring-shaped, the waste paper is not damaged. The used paper in the rotating drum F is sequentially discharged to the outside from the used paper discharge port 8. The string separated from the waste paper is moved toward the collection means C by the wind generated by the discharge means. As the rotating drum F rotates, the string is caught on a pin 18 that protrudes inside the rotating drum F due to its own weight. The string collected on the pin 18 in this way is in the process where the pin 1 protrudes outside the rotating drum F due to its own weight due to the rotation of the rotating drum F.
Leave from 8. In this way, the strings detached from the pins 18 are sequentially discharged to the outside from the string discharge port 9 of the rotating drum F by the wind generated by the discharge means.

〔Effect of the invention〕

As explained above, according to the present invention, the extremely useful effect of being able to easily and reliably separate waste paper and the strings binding them together with high efficiency is brought about.
