Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a waste compaction device for processing waste paper and the like.

[Technical background of the invention and its problems]

Conventionally, in order to dispose of waste paper, it is known that the paper is compressed to reduce its volume and then packaged and disposed of.

In this case, the waste is generally introduced into the compression chamber and the ram for the compression chamber is moved laterally to compress it.

However, when compressing loose waste such as paper cut from a shredder, the waste accumulates at the bottom and there is less at the top. It also has a lot of restoring force and tends to collapse as the ram retreats.

[Purpose of invention]

This invention attempts to improve the above points,
The object is to be able to sufficiently compress the waste as a whole to minimize its volume, and to make it difficult to collapse and to easily carry out the process of cutting the waste.

[Summary of the idea]

The present invention includes a waste input chamber, a waste compression chamber connected to the front of the input chamber, a gate that can be opened and closed at the front of the compression chamber, and a rear part of the input chamber. a compression cylinder device having a compression ram provided in the input chamber and movable from the input chamber to the compression chamber; and a storage opening located at the front of the compression chamber at an upper position and at a position facing the front of the compression chamber. a receiver box provided so as to be freely rotatable and reversible, and the compression ram has a curved sloped portion at the lower front thereof along a rotation locus of the edge of the storage opening of the receiver box. It is characterized by the fact that a protrusion is formed at the upper part of the front surface, and the waste is uniformly compressed in the compression chamber and taken out to the receiving box.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a waste input chamber having a horizontal rectangular tube shape, and a hopper 2 is provided above the top opening of the input chamber 1.

A waste compression chamber 3 having the same cross-sectional shape as the input chamber 1 is connected to the front opening of the input chamber 1, and a gate 4 is provided at the front opening of the compression chamber 3 so as to be movable up and down. The tips of a piston rod 6 of a gate cylinder device 5 erected on the outside between the compression chambers 3 are connected to the upper portions of both sides of the compression chamber 3 .

The gate 4 moves up and down through the forward and backward movement of the piston rod 6 by synchronized operation of the gate cylinder devices 5 on both sides, thereby opening and closing the front opening of the compression chamber 3.

A frame 7 having the same cross-sectional shape as the charging chamber 1 is connected to the rear opening of the charging chamber 1, and a compression cylinder device 8 is provided within the frame 7.
A compression ram 10 is attached to the tip of the piston rod 9 of the compression cylinder device 8, and an upper plate 11 extends from the rear upper part of the ram 10.

Further, a curved inclined portion 12 is formed at the lower front of the ram 10, and a protruding portion 13 is formed at the upper front.

The operation of the compression cylinder device 8 moves the ram 10 back and forth between the rear end of the charging chamber 1 and the front end of the compression chamber 3 through the movement of the piston rod 9.

A lower rear end of a receiving box 15 is provided on a support base 14 at a position in front of the compression chamber 3 so as to be rotatable and reversible around a support shaft 16 .

This receiving box 15 has a storage opening 17 formed on the top surface and an access opening 18 on one side.
A leg body 19 is provided at the lower part of the front end.

Further, a reversing cylinder device 2 is provided on the outer wall surface of the compression chamber 3.
The base of the reversing cylinder device 21 is rotatably attached to the base thereof, and the tip of the piston rod 22 of the reversing cylinder device 21 is rotatably attached to the outer surface of the other side wall of the receiving box 15.

Then, by the operation of the reversing cylinder 21, the receiving box 15 is rotated through the forward and backward movement of the piston rod 22, and the reversible box 15 is in a state with the storage opening 17 on the top surface facing upward, and a state in which the receiving box 15 is oriented sideways with the top surface facing upward. The storage opening 17 of the compression chamber 13 is rotated in a state opposite to the front end opening surface of the compression chamber 13.

Further, the curved inclined portion 12 of the compression ram 10 is formed into a curved surface along the rotation locus of the edge 15a of the storage opening 17 of the receiving box 15, that is, a curved surface centered on the support shaft 16. ing.

Note that a storage bag made of vinyl or the like is removably mounted inside the receiving box 15.

Next, the operation will be explained.

Normally, the ram 10 is at the A position at the front of the charging chamber 1 and the rear of the compression chamber 3, and when waste is charged into the hopper 2, this is detected by a phototube device and the compression cylinder device 8 is activated. Then, the ram 10 retreats to position B at the rear of the loading chamber 1.

At this time, the waste on the upper plate 11 of the ram 10 is
Scraped inside.

Then, the compression cylinder 8 is operated forward, and the ram 10 advances to position C, forcing the waste in the charging chamber 1 into the compression chamber 3 and compressing it.

At this time, since the front lower part of the ram 10 has a curved sloped part 12, the waste from the lower part is pushed forward and upward along the sloped part 12, and the protruding part 13 , the waste above is also strongly compressed.

This operation is repeated as the waste is input, and the waste is compressed against the gate 4 in the compression chamber 3. When the waste in the compression chamber 3 reaches a predetermined pressure, the pressure switch detects this and the ram 10 backs up slightly and waste gate 4
Release the pressure a little.

Then, the gate cylinder device 5 is actuated to open the gate 4.
rises and opens the front of the compression chamber 3.

After detecting that the gate 4 is fully opened, the compression cylinder device 8 is activated and the ram 10 moves forward from the compression chamber 3 to position D, where it is slightly inside the receiving box 15.
Push out the blocked waste in the receiving box 15
The container is stored by being pushed into the storage bag attached to the receiving box 15 through the storage opening 17 of the container.

In this way, by slightly inserting the ram 10 into the receiving box 15 and pushing it, the waste is further compressed by the restoring force.

Then, the ram 10 retreats to position C at the front of the compression chamber 3.
Further, the reversing cylinder device 21 is operated and the receiving box 15
is rotated and reversed by 90 degrees using the support shaft 16 as a fulcrum.

At this time, the edge 15a of the storage opening 17 of the receiving box 15 rotates upward along the curved inclined part 12 of the ram 10, and the receiving box 1
Waste within 5 will not spill.

In this state, the ram 10 retreats to position A, and the gate 4 descends.

Then, the bagged waste in the receiving box 15 is taken out from the access opening 18 on one side, a new storage bag is attached to the waist receiving box 15, and the receiving box 15 is rotated and reversed to pass through the gate 4. Connect to compression chamber 3.

In addition, in practice, the compression ram 10 may be formed into a substantially V-shape when viewed from above at the front, as shown in FIG. 5, so that the waste can be distributed and compressed to the left and right.

[Effect of idea]

According to the present invention, when compressing waste with a compression ram, the front lower part of the ram has a curved slope, so
The waste at the bottom is pushed forward and upward along the slope,
In addition, since the protruding part is provided above this inclined part, the waste above is also strongly compressed, and the waste can be sufficiently compressed overall. Moreover, the waste can be compressed in the compression chamber before being received. Since the waste is taken out into a box, it is possible to compress the waste into blocks, minimize the volume, and make it difficult to collapse.

Furthermore, when taking out the waste in the receiving box, the edge of the receiving box's storage opening rotates upward along the curved slope of the ram, preventing the waste in the receiving box from spilling out. Moreover, since the opening of the storage bag for compressed vinyl or the like is on the top surface, it is possible to easily tie the bags without scattering waste materials around them.

Furthermore, since the loading chamber and the unloading section that have been processed are on the same horizontal level, the height of the entire machine can be lowered by installing a separate hydraulic unit, etc. Therefore, the loading position is also low, making it easier to load garbage. Easy to use, shredder
It can also be easily connected to other pre-processing machines.
