Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized magnetic sorting machine for collected items, which has a function of automatically separating and collecting the collected items such as empty cans mainly containing iron and aluminum. .

[0002]

2. Description of the Related Art Conventionally, in an empty can collecting box installed at a specific place such as on a road or in a station, without separating the empty cans mixed with iron cans and aluminum cans from the inlets. There are many types that can be stored. In addition, such a magnetic sorting machine for collected materials used for separating the empty cans after collection is a relatively large-sized one that sucks and separates a large amount of collected materials in which magnetic materials and non-magnetic materials are mixed using a lifting magnet or the like. Industrial ones are commonly used.

[0003]

In the case of the above-mentioned empty can collection box, since the type in which iron cans and aluminum cans are stored without separation is generally the mainstream, separation work is separately performed after collection. This is inconvenient from the perspective of separate collection of empty cans.

In addition, since the magnetic sorter for collected materials has a function of sucking and separating the magnetic material of the collected materials by a single lifting magnet, if iron cans, aluminum cans and the like are mixed when collecting empty cans, for example There is a problem that both cans cannot be separated and collected functionally and efficiently because only the cans are separated by suction. In particular, the fact that aluminum cans cannot be separated efficiently is a drawback that makes it difficult to meet recent demands for resource reuse.

The present invention has been made to solve such a problem, and its technical problem is to be able to automatically and efficiently separate and collect recovered materials of a magnetic material and a non-magnetic material, and
An object of the present invention is to provide a magnetic sorting machine for collected materials that does not occupy an occupied space that can be easily installed in a specific place.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A magnetic sorter for collected materials according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a partially removed basic structure (structure of a main body part as a main part) of a magnetic sorter for collected materials according to an embodiment of the present invention.

This collected matter magnetic sorting machine has a drive drum 5 which is rotationally driven , and is parallel to the axial direction of the drive drum 5.
Rotatable with a certain distance from the drive drum 5
In the circumferential direction on the outer peripheral surface of the inner drum 1
Multiple units are installed along each
It extends in the axial direction of the ram 1 and one half is the N pole and the other
One half of the two is made S-pole, and the poles adjacent in the circumferential direction are paired.
A cylindrical non-magnetic body that is rotatably supported coaxially with respect to the internal drum 1 with a predetermined gap between the first magnets 2 and the plurality of first magnets 2 that are made to be poles. a driven drum comprising an external rotary drum 3, drive drum 5 and both the that scum communication on the outer peripheral surface of the non-magnetic outer rotatable drum 3 which are in the driven drum 3, the predetermined on the outer surface
A belt 4 provided with a plurality of partition plates 10 at intervals.
To form a magnetic gradient such that the magnetic attraction force acting on the outer surface of the lower traveling path of the belt 4 becomes weaker as it approaches the driving drum 5 and becomes stronger as it approaches the driven drum 3 . Belt 4 near driven drum 3
The one end close to the inner table surface of the lower running path, and a body portion and a second magnet 6 that the other end is arranged to be inclined so as to be separated from the inner surface toward the drive drum 5 side A frame 8 (only one side is shown) from both sides of each axis of the driving drum 5 and the driven drum 3 in the main body
The waterproof and dustproof cover 9 is provided along the moving direction of the belt 4 locally at a position slightly separated from the belt 4 and each partition plate 10 in the frame 8. It is configured so as to cover the gap with 4.

Of these, the second magnet 6 in the main body is fixedly attached to the support member 7 by adhesion, and the drive drum 5, the driven drum 3, and the belt 4 drive the drive drum 5 for rotation. And a drive device (not shown) for forming a belt conveyor.

In the case of this magnetic separator for collected materials, a collected material of magnetic material and non-magnetic material is provided between the partition plates 10 on the outer surface of the belt 4 provided with a plurality of partition plates 10. The belt 4 moves in the direction of the arrow as the drive drum 5 rotates in a state where, for example, an empty can made of iron and aluminum is dropped and placed. Therefore, when the empty can approaches each of the first magnets 2 on the driven drum, if it is an iron can made of a magnetic material, the magnetic attraction force of each first magnet 2 is applied to the outer surface of the belt 4. The non-magnetic rotary drum 3 is moved by being pushed by the partition plate 10 while being attracted to the magnetic disk, and receives the magnetic attractive force of the second magnet 6 attached to the support member 7 in the vicinity of the driven drum at a position where the non-magnetic rotary drum 3 is rotated about half a turn. The non-magnetic external rotating drum 3 moves from the outer peripheral direction to the horizontal direction without falling, but the second magnet 6 becomes weaker as the magnetic attraction force approaches the driving drum 5 and becomes stronger as it approaches the driven drum. Since it is arranged to have such a magnetic gradient, as the belt 4 advances, the magnetic attraction force gradually weakens, and the iron can becomes a belt 4 at a predetermined position.
On the outer surface of the.

On the other hand, if the empty can is an aluminum can made of a non-magnetic material, it does not receive any magnetic attraction force even when it approaches each of the first magnets 2 of the driven drum, so that the non-magnetic property of the driven drum is non-magnetic. It falls from the outer peripheral tip of the external rotation drum 3.

That is, the magnetic sorting machine for collected materials is
Of the magnetic material and the non-magnetic material (iron can, aluminum can) by changing the arrangement of the second magnet 6 and the second magnet 6 and adjusting the inclination of the magnetic gradient of the second magnet 6 respectively. The position can be set arbitrarily. In addition, since the frame 8 is provided with the waterproof and dustproof cover 9, the usage conditions may be, for example, soft drinks such as undrinked drinks left over, or dust or the like may not enter the inside of the belt conveyor. Operational stability is guaranteed over a long period of time.

By the way, such a magnetic sorter for collected materials stores the above-mentioned main body portion and a member having an input port for inputting the collected material by an iron can or an aluminum can in the storage portion, and then the main body. When a plurality of collection boxes for storing and collecting the separated each in the department are installed corresponding to the falling positions of the iron can and the aluminum can, the iron can and the aluminum can are installed. Can be efficiently and automatically separated and collected. Further, in the case of such a magnetic sorter for collected matter, the basic structure of the main body described above makes the entire structure a compact structure that does not occupy an occupied space, so that it can be attached to a general vending machine.

In the above-described embodiment, the magnetic separator for collected materials when the collected material is an empty can and the recovery box storing the magnetic sorting machine are described, but the recovered material is not limited to the empty can.

[0018]

As described above, according to the magnetic sorting machine for collected materials of the present invention, the basic structure of the driving drum and the driven drum in the driven drum on which the belt is stretched is improved to drive the driven drum. Parallel to the axial direction of the drum and away from the drive drum
Rotatable internal drum arranged at a distance constant, this
Multiple units are arranged along the circumferential direction on the outer peripheral surface of the internal drum of
Each extending in the axial direction of the internal drum
And one half is the north pole and the other half is the south pole.
The first magnets, which are arranged so that the poles adjacent to each other in the circumferential direction are opposite to each other , and the first magnets can be coaxially rotated with respect to the internal drum with a predetermined gap therebetween. after having a structure consisting of supported cylindrical non-magnetic body outside rotary drum, one end close with the driven drum near the inner <br/> table surface of the lower running path of the belt, and the other end driving the drum Towards the side
The magnetic attraction force acting on the outer surface of the lower traveling path of the belt becomes weaker as it approaches the drive drum and approaches the driven drum by the second magnet that is inclinedly arranged so as to be separated from the inner surface. On the outer surface of the belt, a magnetic gradient that becomes stronger in accordance with the above is formed , and the arrangement of the first magnet and the second magnet and the inclination of the magnetic gradient of the second magnet are changed to be adjustable. By arbitrarily setting the respective falling positions of the magnetic material and the non-magnetic material that are to be placed, the collected objects can be automatically and efficiently separated and collected. In particular,
In addition to storing the main body of the magnetic sorter for collected materials and the member having the inlet for charging collected materials in the storage unit,
By installing multiple recovery boxes for accommodating and recovering each of the separated materials in the main body part in correspondence with the falling position of each of the collected materials of magnetic material and non-magnetic material, the separated collection of collected materials can be performed. This is done automatically and becomes convenient. For example, if the collected product is an empty can, it can be reasonably sorted and collected even if it is an empty can containing both iron and aluminum. The convenience of collecting and reusing aluminum cans made of magnetic materials will contribute to recent demands for resource and energy conservation. Further, in the case of this magnetic sorter for collected materials, the whole body including the main body is constructed in a small scale and does not occupy an occupied space, so that it can be easily installed in a specific place such as on the road or on the premises of a station At the same time, it becomes possible to attach it to a vending machine that is generally installed in stores.
