BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting structure for surely sorting iron cans and aluminum cans in an empty can processing machine for crushing empty cans and sorting and collecting them by iron can and aluminum can.

[0002]

2. Description of the Related Art With the spread of vending machines, the sales amount of soft drinks, drinks such as beer, and canned foods containing portable foods have increased remarkably. Used cans are sorted into iron cans and aluminum cans for the purpose of reusing resources, and they are collected in a crushed state to improve the efficiency of recovery work. In order to collect empty cans, an empty can processing machine is used that has the function of continuously crushing a large amount of empty cans and automatically sorting the crushed empty cans into iron cans and aluminum cans using a permanent magnet. . The selection of empty cans is performed before or after crushing. In the method of sorting before crushing, since the empty cans to be crushed have a large volume, the empty can transport mechanism and the sorting mechanism are large-scaled, and it is required to separately crush the sorted empty cans. The method of selecting after crushing has an advantage that the selecting mechanism and the like can be downsized, but the belt or the like for conveying the crushed empty cans is easily damaged.

As a method of selecting after crushing, for example, Japanese Utility Model Publication No. 61-38791 discloses an empty can processing machine shown in FIG. The movable compression plate 13 provided inside the empty can processor body 10 vibrates with a small amplitude and a short cycle as it goes downward due to the large and small cams 14 and 15 which are rotated by the driving force of the driving source 16. The empty can inserted between the fixed compression plate 12 and the movable compression plate 13 moves downward along the movable compression plate 13 by its own weight. At this time, since a large number of empty cans are shaken by the vibration of the movable compression plate 13, they are sequentially sent out downward without being entangled with each other. The empty can moved to the lower side of the movable compression plate 13 is adjusted to the gradually narrowing gap between the fixed compression plate 12 and the movable compression plate 13 while moving to the final end of the fixed compression plate 12 and the movable compression plate 13. It is gradually crushed. When the completely crushed empty can is discharged from the lower ends of the movable compression plate 13 and the fixed compression plate 12, it is gradually vibrated by the carrier plate 22 that vibrates in accordance with the movement of the movable compression plate 13 arranged below. Is sent downward to.

A semi-circular permanent magnet 25 rotatably attached is waiting under the carrier plate 22, and among the crushed empty cans, iron cans are attracted to the permanent magnets 25 and the guide plate 28. Sent to the side. The iron can sent to the guide plate 28 side travels along the guide plate 28 and falls into the storage container 29a standing by below. On the other hand, the permanent magnet 25
The aluminum cans that have not been adsorbed by the storage container 2 pass through the guide plate 27 located below from the lower end of the carrier plate 22.
It falls into 9b. Therefore, just by inserting a large amount of empty cans between the fixed compression plate 12 and the movable compression plate 13, the inserted empty cans are sequentially crushed by the vibration operation of the movable compression plate 13 and the crushed empty cans rotate. Since it is selected by the permanent magnets 25 arranged in this state, a large amount of empty cans can be processed in a short time without requiring manpower.

[0005]

In the empty can processing machine shown in FIG. 1, the movable compression plate 13 as a whole is vibrated in small steps by the large and small cams 14 and 15 which are rotated by the driving force of the driving source 16 so that the empty can processing is performed. Send a large amount of empty cans to the crushing side. Therefore, when a large amount of empty cans are pushed up by the small vibrations of the movable compression plate 13, a plurality of empty cans collide with each other and cause noise during empty can processing. Further, since the entire movable compression plate 13 is vibrated by the driving force of the drive source 16, it is necessary to consider the weight of the large number of empty cans that are thrown in in addition to the weight of the movable compression plate 13 itself. There is also a problem that it is necessary to increase the driving force of 16.

Therefore, the present inventors have developed an empty can processing machine capable of extremely reducing the noise generated by the collision of empty cans and also reducing the driving force required for empty can processing. Filed as -343224. In this type of empty can processor, it is important to completely separate iron cans and aluminum cans. For example,
When the iron can is mixed in the aluminum can, harmful Fe may be mixed as an impurity when the aluminum can is used as an aluminum resource. The present invention has been devised in order to solve such a problem, and by making the ability to sort empty cans into iron cans and aluminum cans adjustable, it is possible to ensure reliability even for empty cans of various sizes. The purpose is to carry out sorting work.

[0007]

In order to achieve the object, the sorting mechanism of the present invention forms an empty can that falls by its own weight from an empty can storage portion provided at an upper part of an empty can processing machine body between a fixed plate and a rotating plate. In an empty can processing machine that crushes in a crushing space and sorts and collects it into iron cans and aluminum cans, the direction from the crushing space to the fixing plate side rather than the surface extending vertically downward from the lower end of the fixing plate of the crushing part. A magnetic rotating body whose support shaft is offset, a roller body having a diameter smaller than that of the magnetic rotating body, the rotating body being disposed below the magnetic rotating body while maintaining the rotating shaft parallel to the supporting shaft, and the rotating body. It is characterized in that it is provided with a rubber belt stretched between the roller body. Here, the rotary shaft of the roller body is arranged so that its position can be adjusted in a range from a vertically lower position of the support shaft to a lower position of the rotating plate along an arc centered on the support shaft of the magnetic rotary body. Is also possible.

EXAMPLE As shown in FIG. 2, the empty can processor of the present embodiment is provided with a power switch 31, a processing operation start button 32 and a stop button 33 on the front surface of an empty can processor body 30. An open / close lid 34 is rotatably attached to the upper portion of the empty can processing machine main body 30 as shown in FIG. 3, and the empty can processing machine main body 30 is opened with the open / close lid 34 open.
A large amount of empty cans P are loaded from the upper part of. As shown in FIG. 4, a hopper type empty can accommodating portion 35 is provided above the inside of the empty can processor main body 30. The four side plates 36 to 39, which form the empty can housing portion 35, are arranged so that their respective inclination angles are different from each other. Since a large amount of empty cans P put into the empty can accommodating portion 35 can be stored in different postures by the side plates 36 to 39, the empty can accommodating portion can be made in a state in which a large number of empty cans in a stacked state are less entangled with each other. It is accommodated in 35.

A side plate 36 which is a part of the empty can housing portion 35.
Is rotatably attached to the frame member 40 via a shaft 41. On the lower surface side of the side plate 36, a rotating plate 43 having a plurality of protruding members 42 is rotatably attached via a shaft 44. As shown in FIG. 5, the side plate 36 is provided with holes 45 corresponding to the respective protruding members 42.
Each of the projecting members 42 advances and retracts from the hole 45 when the rotating plate 43 performs a contacting / separating operation with respect to the back side of the side plate 36. The lower ends of the side plate 36 and the rotating plate 43 are in contact with a supporting member 48 having a stopper piece 47 of the crush plate 46. Crush plate 4
The lower end of 6 is attached to a rotary arm 50 that rotates about a shaft 49 as a fulcrum. When the crush plate 46 rotates with the rotation of the rotary arm 50, the support member 4 for the crush plate 46 is provided.
8 is displaced, and the stopper piece 47 of the support member 48 moves the rotating plate 4
Push up the lower end of 3. When the rotating plate 43 is pushed up until it comes into contact with the back side of the side plate 36, the side plate 36 is pushed up from this position to the position indicated by the broken line in FIG.

As the side plate 36 rotates in accordance with the forward / backward movement of each protruding member 42 of the rotating plate 43, the empty can accommodating portion 3
The overlapping state of a large amount of empty cans P accommodated in 5 is not broken, and a large amount of empty cans P are not clogged in the empty can accommodating portion 35. Crushing plate 46 that constitutes the crushing portion of the empty can
Reinforcing iron plates 51 and 53 are attached to the opposing surface sides of the fixing plate 52 and the fixing plate 52, respectively. The crush plate 46 is the fixed plate 5.
2, the interval on the lower end side is narrower and that on the upper end side is wider. The empty can P is gradually crushed by the crush plate 46 and the fixed plate 52 as it moves downward due to its own weight. The lower ends of the crush plate 46 and the fixed plate 52 are separated from each other to form a slit-shaped discharge hole 54. A support member 56 that supports the drive motor 55 is provided in the middle of the inside of the empty can processor main body 30. The drive pulley 57 of the drive motor 55 is provided with a circular protrusion 59 that fits into a slide hole 58 provided at the end of the rotating arm 50. The circular protrusion 59 is displaced by the rotation of the drive pulley 57, and when the rotating arm 50 is rotated about the shaft 49 as a fulcrum, the crush plate 46 swings accordingly.

An internal frame 60 located below the crushed portion
Further, as shown in FIG. 6, support members 61 and 62 are provided. A support shaft 64 that supports the rotating body 63a and the receiving pulley 63b of the empty can separation mechanism 63A is rotatably provided between the support members 61 and 62. Rotating body 63a
Is a disk-shaped permanent magnet 63 and a disk-shaped non-magnetic material 63c.
Are alternately fixed to the support shaft 64. The support shaft 64 is located on the left side in FIG. 7 with respect to the plane extending vertically downward from the fixed plate 52, and is provided with a horizontal offset amount L. Arc-shaped grooves 61a and 62a centering on the support shaft 64 are formed in the lower portions of the respective support members 61 and 62. A support shaft 66 that supports a roller body 65 having a diameter smaller than that of the rotating body 63a is fitted into the arcuate grooves 61a and 62a, and is rotatably positioned at an appropriate position. A wide rubber belt 67 is wound in a V shape between the disk-shaped permanent magnet 63 and the roller body 65.

As for the positional relationship of the empty can separating mechanism 63A with respect to the slit-shaped discharge hole 54, the offset amount L is set to the support shaft 6
4 is located slightly to the left of the discharge hole 54. Further, the rotation direction of the rubber belt 67 is counterclockwise in FIG. As a result, the aluminum can discharged from the discharge hole 54 falls on the right circular arc portion of the rotating body 63a and on the wide rubber belt 67 near the lower portion thereof, so that it does not stick to the permanent magnet 63 and falls to the right. . On the other hand,
The iron can is attracted to the permanent magnet 63 and is transported to the left side.
A timing belt 68 is wound around the receiving pulley 63b and the drive pulley 57 of the drive motor 55. When the driving force of the drive motor 55 is transmitted to the receiving pulley 63b via the timing belt 68, the circular permanent magnet 63
And the wide rubber belt 67 also rotates. The storage container 71 below the inner frame 60 has a storage container 6
9, 70 are arranged. Iron cans and aluminum cans are separately stored in the storage containers 69 and 70, respectively.

Next, the operation of the empty can processor of this embodiment will be described. First, with the opening / closing lid 34 on the upper part of the empty can processor main body 30 opened, an empty can is loaded from the upper part of the empty can processor main body 30. The loaded empty cans are accommodated in a hopper type empty can accommodating portion 35. Since the inserted empty cans are oriented in various directions because the side plates 36 to 39 of the empty can processor main body 30 are arranged at different inclination angles from each other, the empty cans are accommodated with the entanglement of the empty cans minimized. It is accommodated in the part 35. When the power switch 31 provided on the front surface of the empty can processor main body 30 is turned on and then the processing operation start button 32 is pressed, the drive motor 55 is driven and the drive pulley 57 is rotated. Then, the circular protrusion 59 is displaced, and the rotating arm 50 rotates about the shaft 49 as a fulcrum. As a result, the rotating arm 5
The crush plate 46 having the lower end attached to 0 swings.

When the crush plate 46 swings toward the fixed plate 52,
The support member 48 provided on the upper end of the crush plate 46 is displaced in the same direction. With the displacement operation of the support member 48, the lower end portion of the side plate 36 is pushed up, and the side plate 36 rotates clockwise. With the displacement operation of the support member 48, the rotating plate 43
The lower end is pushed up and rotates in the same direction. Support member 48
Is further displaced in the same direction, the stopper piece 47 moves the rotating plate 4
It engages with the lower end portion of 3 and further rotates the rotating plate 43 in the same direction. When the crush plate 46 is rotated to the position shown by the chain double-dashed line in FIG. 4, the rotation operation of the side plate 36 and the rotation plate 43 is stopped. As the side plate 36 and the rotating plate 43 rotate, the plurality of protruding members 42 provided on the rotating plate 43 are gradually pushed out from the holes 45 of the side plate 36. The entangled state of a large amount of empty cans P accommodated in the empty can accommodating portion 35 is destroyed by the push-out operation of the side plate 36 from the hole 45 of each protruding member 42 together with the slight pivoting operation.

In this state, the empty can P located between the crush plate 46 and the fixed plate 52 has the reinforcing iron plates 51, 5 respectively.
It is crushed by 3. When the crushing operation of the empty can P is completed, the circular protrusion 59 is displaced in accordance with the rotation operation of the drive pulley 57, and the rotating arm 50 is swung about the shaft 49 as a fulcrum. As the rotating arm 50 swings, the crush plate 46
When is swung clockwise, the crush plate 46 separates from the fixed plate 52. Further, in response to the swaying movement of the crush plate 46 in the same direction, the pushing force of the stopper piece 47 to the lower end portion of the rotating plate 43 is released, and the side plate 36 is pushed back counterclockwise by the weight of the empty can P or the like. After the side plate 36 is pushed back to the home position, the rotating plate 43 further rotates counterclockwise and returns to the home position. At this time, the plurality of protruding members 42 of the rotating plate 43
Is in a state of not protruding upward from the hole 45 of the side plate 36.

As described above, the movement of the side plates 36 of the respective protruding members 42 of the rotating plate 43 from and into the holes 45 and the side plates 3 are performed.
By the rotating operation of 6, the entanglement due to the respective weights of the large amount of empty cans P accommodated in the empty can accommodating portion 35 is minimized, so that the empty cans P are sequentially delivered to the gap between the crush plate 46 and the fixing plate 52. . The empty can P crushed by the rocking motion of the crush plate 46 falls by its own weight from the slit-shaped discharge hole 54 provided at the lower ends of the crush plate 46 and the fixed plate 52, and moves to the empty can selection mechanism 63A side. . On the empty can sorting mechanism 63A side, the driving force of the driving motor 55 is applied to the receiving pulley 63b through the timing belt 68, and the driving force causes the rotating body 63 to rotate.
As a rotates, the roller body 65 also rotates through the wide rubber belt 67.

When the empty can P falls on the disk-shaped permanent magnet 63 attached to the rotating body 63a of the empty can selecting mechanism 63A, the aluminum can slides on the wide rubber belt 67 and drops to the storage container 70 side. On the other hand, the iron can has a permanent magnet 6
It is adsorbed by 3 and pulled in counterclockwise. Since the iron can is attracted to the permanent magnet 63 via the wide rubber belt 67, when the iron can moves to the roller body 65 side, the attraction force of the permanent magnet 63 is released and the iron can falls into the storage container 69 by its own weight. When the conventional sorting mechanism is used, an iron can dropped from the discharge hole 54 onto the rubber belt 67 may be sent to the storage container 70 against the magnetic force of the permanent magnet 63. When the iron can is mixed into the aluminum can, a horizontal offset amount L is provided between the fixed plate 52 and the support shaft 64, and the position of the roller body 65 is adjusted along an arc centered on the support shaft 64. It is suppressed by that.

When the support shaft 64 is horizontally displaced from the fixed plate 52 by the offset amount L, the empty can P that drops from the discharge hole 54 is provided on the winding portion of the rotating body 63a and the rubber belt 67 moving upward. It hits the inclined surface and is smoothly attracted to the permanent magnet 63. The iron can is also attracted to the permanent magnet 63 while sliding on the inclined surface of the rubber belt 67. The attracted iron can is conveyed by the rubber belt 67 running in the counterclockwise direction, goes around the permanent magnet 63, and drops to the storage container 69 side. On the other hand, since the non-magnetic aluminum can is not affected by the magnetic force, the non-magnetic aluminum can falls by its own weight along the rubber belt 67 or at a predetermined reflection angle and is fed into the storage container 70. The accuracy of sorting iron cans and aluminum cans is
Due to the size and weight of the product, it may differ each time the collection work is performed. In this respect, in the present embodiment, the sorting accuracy is adjusted by changing the turning angle θ (see FIG. 9) of the roller body 65 around the support shaft 64.

In a work environment in which an iron can easily mixes into an aluminum can, the turning angle θ is set to be large and the influence of the magnetic force acting on the iron can after crushing is set to be large. On the other hand, the turning angle θ can be reduced in a situation where the degree of mixing of the iron can is small.
In this way, by adjusting the turning angle θ, the sorting work is set according to the empty can collection location, and the sorting of aluminum cans and iron cans can be performed with high accuracy. The turning angle θ is adjusted within a range of, for example, 30 degrees or less so that the rubber belt 67 on the dropping side of the aluminum can tilts counterclockwise from the vertical line, although it depends on the diameter and the positional relationship between the rotating body 63a and the roller body 65. It is preferable. Then, by changing the turning angle θ according to the state of the empty can P to be sorted, the aluminum can and the iron can are reliably sorted.

[0020]

As described above, in the present invention, the magnetic rotating body and the small-diameter roller body of the sorting mechanism arranged below the crushing mechanism are arranged in the vertical direction, and the wide rubber belt is formed in the V shape. The upper end of the wound empty can sorting mechanism is positioned offset with respect to the discharge hole of the crushing portion. Therefore, the crushed empty cans are reliably sorted into aluminum cans and iron cans. Further, the sorting ability can be further improved by adjusting the positional relationship of the lower roller body with respect to the magnetic rotating body.
