Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing method and apparatus for reusing empty can resources such as aluminum materials.

[0002]

2. Description of the Related Art For the purpose of reusing the material of a can that has been used for a container such as juice, a used empty can is mechanically compressed and recovered in a state where its outer volume is reduced. Various processing machines have appeared.

When an empty can is compressed by such a processor,
In general, the empty can is crushed simply by applying a pressing force from the outside without any treatment.

[0004]

However, the above conventional compression processing of empty cans has the following problems. That is, the caulking portions (top edge and bottom edge) that form the high-strength portion of the empty can cannot be effectively crushed, and even if they are compressed once, their volume increases again due to the spring effect of the empty can material. Therefore, the volume of the empty can is reduced to about 1/5 before compression.

In addition, in today's juice cans and the like, the top surface portion having the drinking mouth is formed of aluminum material and the other portion is formed of steel material in order to reduce the cost of materials. Even a can is crushed as a whole, so it is not possible to separate and collect each type of material.

It is an object of the present invention to eliminate such a problem and to make it possible to rationally reuse an empty can resource.

[0007]

In order to achieve the above object, in the first processing method according to the present invention, as described in claim 1, the peripheral wall of the empty can is cut at a portion near the top surface. The top surface part is collected as it is, and the bottom side part is flattened and collected separately from the top surface part.

According to this treatment method, only the top surface material is separated and recovered, and the bottom side portion has a shape in which the top surface portion does not exist, so that the rigidity of the whole is reduced and it is relatively easy. Will be crushed by.

According to a second aspect of the present invention, as described in claim 2, an empty can rotation supporting means for rotating the empty can at a fixed position, a portion near the top surface and a bottom surface of the peripheral wall of the empty can. A cutting blade means that is simultaneously or selectively pressed against a nearby location is provided, and the cutting blade means cuts both the location near the top surface and the location near the bottom surface of the peripheral wall of the empty can during rotation, or one of these locations. It acts as if to do.

According to this processing apparatus, only the top surface portion or both the top surface portion and the bottom surface portion are separated from the empty can. At this time, both the top surface portion and the bottom surface portion are separated from the empty can. Then, the central cylindrical portion is left, but the cylindrical portion has a significantly reduced rigidity as compared with the empty can, and is easily crushed.

According to the third aspect of the present invention, the second processing device pushes to an empty can rotation supporting means for rotating the empty can at a fixed position and a position near the top surface and the bottom surface of the peripheral wall of the empty can. A cutting blade means to be applied is provided, and in this case, the empty can rotation supporting means includes a supporting roller for supporting the vicinity of the bottom surface and the vicinity of the top surface of the peripheral wall of the empty can, and a caulking portion around the bottom surface or the top surface. And a pressing roller for pressing the supporting roller, a pressing operation lever for pressing the pressing roller, and a driving means for rotationally driving the supporting roller or the pressing roller. Is equipped with a cutting blade that cuts a portion near the top surface of the peripheral wall while the empty can is rotating, and a cutting blade that also cuts a portion near the bottom surface of the peripheral wall.

According to this processing apparatus, the supporting roller and the pressing roller are in a state in which the caulking portion of the empty can is clamped by the operation of the pressing operation lever, and under this state, they are rotated manually or by the power of a motor or the like. It Then, this rotation causes the empty can to rotate with a strong force. The cutting blade is pressed against the peripheral wall of the empty can while it is rotating, and cuts a portion near the top surface or a portion near the bottom surface.

According to a third processing apparatus of the present invention, as described in claim 4, the peripheral wall of the empty can introduced from the opening is relatively located above the main body frame having the opening into which the empty can is introduced. A cutting treatment device for dividing the empty can into two parts, a top face part and a bottom side part, by cutting at a location near the top face, and a flattening treatment device for flattening the bottom side part. Further, below the cutting processing device and the flattening processing device, there is provided a recovery box having a partitioning section of the top surface portion and a partitioning section of the flattened bottom side portion.

According to this processing apparatus, the top surface portion and the bottom side portion of the empty can which is thrown in through the opening are automatically separated so that they can be housed in the respective compartments of the collection box independently. At this time, the bottom portion is flattened more easily than the empty can as described above, and the spring effect due to the empty can material is also reduced, so that the volume is greatly reduced.

Next, in the second processing method according to the present invention, as described in claim 5, the peripheral wall of the empty can is cut at a portion near the top surface and a portion near the bottom surface, and the top surface portion and the bottom surface portion are recovered as they are. On the other hand, the central cylindrical portion is flattened and then collected, and at this time, at least the top surface portion is collected separately from the bottom surface portion and the central cylindrical portion.

According to this treatment method, the top surface portion and the bottom surface portion are separated from the empty can, and the remaining central cylindrical portion has a drastically reduced rigidity as described above and can be crushed very easily.
Moreover, since the top surface portion is independently recovered, only the top surface material is separated.

According to a fourth processing apparatus of the present invention, as described in claim 6, the peripheral wall of the empty can introduced from the opening is provided at a relatively upper portion of the main body frame having the opening into which the empty can is introduced. A cutting device that cuts the empty can into three parts, a top surface part, a central cylindrical part, and a bottom surface part, by cutting near the top surface and near the bottom surface, and the center of the empty can manufactured by this cutting processing device. A flattening processing device for flattening the cylindrical portion is provided, and a cutting section of the top surface section and a flattening section of the flattened central cylindrical section and bottom surface section are further provided below the cutting processing apparatus and the flattening processing apparatus. It shall be provided with a recovery box provided.

According to this apparatus, the empty can introduced from the opening is divided into the top surface portion, the central cylindrical portion and the bottom surface portion, and these respective portions are accommodated independently in the respective compartments of the recovery box. In this case, the central cylindrical portion has a significantly reduced rigidity as compared with the empty can, is crushed very easily, and effectively reduces the volume, and only the top surface material is separated. .

1 and 2 are structural explanatory views of a processing apparatus according to a first embodiment of the present invention. The processing apparatus of the present embodiment comprises an empty can rotation supporting means for rotating the empty can w at a fixed position, and a cutting blade means for cutting the peripheral wall of the empty can w at a position near the top surface and a position near the bottom surface. Become.

The empty can rotation supporting means is as follows.

That is, reference numerals 1 and 2 denote rotating shafts arranged in parallel, and both ends of each shaft 1, 2 are rotatably supported at a fixed position by a plurality of bearings 3 ... Fixed to a stationary table (not shown). Has been done.

Two supporting rollers 1a and 1b, a gear 1c and a rotation operating handle 1d are fixed to one rotating shaft 1, and two supporting rollers 2 to the other rotating shaft 2.
a, 2b and the gear 2c are fixed. In this case, the supporting rollers 1a, 1b, 2a, 2b are not supposed to have their peripheral surfaces knurled, and the gears 1c and 2c are not necessary.
Are interlocked and coupled via an intermediate gear 4 mounted on a stationary table (not shown).

Reference numeral 5 denotes a shaft 6 arranged in parallel with the rotary shafts 1 and 2.
With a pressing operation lever provided so as to be swingable around, the support plate 9 on which the two pressing rollers 7a and 7b are pivotally mounted 8 and 8 is swingable around the coupling shaft 10 in the middle of its length. It is laid up. The pressing rollers 7a and 7b are set so as to come into contact with the supporting rollers 1b and 2b in a vertical relationship, and the peripheral surface is knurled.

The cutting blade means comprises a cutting blade 11 for cutting the peripheral wall of the empty can w near the top surface, and a cutting blade 12 for cutting the peripheral wall near the bottom surface. The tip of each of the cutting blades 11 and 12 is independently pressed against the peripheral wall of the empty can w through the spring force by operating the cutting blade operating lever. The cutting blades 11 and 12 may be rod-shaped fixed blades or disc blades that are rotatable as indicated by reference characters a1 and a2. It is preferable that the positions in the first and second directions can be changed and adjusted.

The apparatus of this embodiment constructed as described above is used as follows. The cutting blades 11 and 12 are retracted to the positions shown in FIG. 1 by operating a cutting blade operating lever (not shown), and then the empty can w is supported by the support rollers 1a, 1b, 2 and 2.
Place on a, 2b. At this time, the top surface portion of the empty can w (which is provided with the drinking spout and its tab) w1 is fitted on the supporting rollers 1b and 2b.

After the pressing operation lever 5 is retracted upward and the longitudinal position of the empty can w is accurately adjusted,
The caulking portion on the peripheral edge of the top surface portion w1 is located between the supporting rollers 1b and 2b and the pressing rollers 7a and 7b.

On the other hand, a cutting blade operating lever (not shown) is operated to press one cutting blade 12 against the peripheral wall of the empty can w in the direction of arrow f1 via a spring force and to keep the position of the cutting blade 12. Lock the position of the operating lever.

Thereafter, the rotation operation handle 1d is rotated while the pressing operation lever 5 is being pressed downward.

As a result, the supporting rollers 1b, 2b and the pressing rollers 7a, 7b are in a state in which the caulking portion of the empty can w is strongly sandwiched, and the rotation of the rotary shaft 1 is caused by the gears 1c, 4 ,.
It is transmitted to the other rotating shaft 2 via 2c. For this reason,
The empty can w is mainly rotated by the supporting rollers 1b and 2b and is rotated at a fixed position. During this rotation, the cutting blade 12 cuts a portion near the bottom surface.

Thus, after the bottom surface w2 is separated,
The rotation operation of the rotation operation handle 1d is stopped, and the cutting blade operating lever is operated to retract the cutting blade upward.

Then, by operating another cutting blade operating lever, the other cutting blade 11 is pressed against the peripheral wall of the empty can w in the direction of arrow f2 via the spring force in the same manner as described above, and is operated again in the same procedure as described above. As a result, the cutting blade 11 cuts a portion near the top surface. As a result, the top surface portion w1 is separated from the empty can main body portion, and the empty can w is eventually divided into three parts of the top surface portion w1, the central cylindrical portion w3, and the bottom surface portion w2.

After that, the operation lever is retracted upward and the cutting blade is retracted to the original position. Thereafter, the same operation is repeated for each empty can.

When only the top surface w1 of the empty can w thus obtained is made of a different material (aluminum material), only this material is separated and collected, and the central cylindrical portion w3 is flattened by an appropriate pressing device to make a bottom surface. Collect with Part w2. As a result, only the aluminum material portion of the empty can w is collected in a separated state. Further, since the rigidity of the central cylindrical portion w2 is remarkably reduced and is completely flattened and the influence of the spring effect of the empty can material is reduced, the outer volume of the entire empty can material is reduced to about 1/20 of the original volume. It is possible (this is a dramatic improvement compared to the conventional reduction of only about 1/5). When the whole empty can w is made of the same material, it is not necessary to separate the divided parts.

In the use of the apparatus of this embodiment, only one cutting edge 11 may be used to separate only the top surface w1 from the empty can w. Even in this case, only the top surface w1 can be separated and recovered, and the rigidity of the bottom portion is greatly reduced as compared with the state in which the top surface w1 is not separated, and the flattening is easily performed by the pressing device. Therefore, the outer volume of the whole empty can w after flattening is significantly reduced as compared with the conventional one.
