DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can processing machine which has a function of crushing a large number of empty cans and separating them into iron cans and aluminum cans.

[0002]

2. Description of the Related Art Conventionally, collected empty cans have been classified into iron cans and aluminum cans from the viewpoint of reducing processing costs and the like, and then reused. When collecting empty cans, the empty cans are crushed by an empty can processor and then collected in order to efficiently collect the empty cans.

By the way, as such an empty can processing machine,
There is a type having a function of continuously crushing a large number of empty cans and automatically sorting the crushed empty cans into an iron can and an aluminum can using a permanent magnet. The cases where the empty cans are automatically sorted are roughly classified into those performed before the crushing process and those performed after the crushing process. However, since the former is intended for large empty cans to be crushed, the mechanism for transporting the crushed empty cans and the mechanism for separating them are large, and the separated cans are separately separated. There was a problem that it had to be processed. On the other hand, the latter has the advantage that the separation mechanism and the like can be miniaturized because the empty can is separated after being crushed, but the belt for transporting the crushed empty can is easily damaged. There was a problem.

In order to solve such a problem, Japanese Utility Model Publication No. 61-38791 discloses, for example,
An empty can processing machine as shown in FIG. 1 is disclosed. That is, as shown in the figure, the amplitude of the movable compression plate 13 provided inside the empty can processing machine main body 10 decreases as it goes down due to the large and small cams 14 and 15 rotated by the driving force of the driving source 16. It vibrates at a small and short cycle.

When a large number of empty cans are charged between the fixed compression plate 12 and the movable compression plate 13, these empty cans
It moves downward by its own weight along 3. In addition, since these empty cans are shaken by the vibration of the movable compression plate 13,
They are sequentially sent downward without being entangled with each other.

The empty can that has moved below the movable compression plate 13 gradually narrows 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 according to the gap. 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 disposed below the movable compression plate 1
The sheet is gradually sent downward by the transport plate 22 which vibrates in accordance with the movement of No. 3. A semi-circular permanent magnet 25 rotatably mounted is waiting below the transport plate 22. Of the crushed empty cans, the iron can is attracted to the permanent magnet 25 and is directed to the guide plate 28 side. Will be sent out. The iron can sent out to the guide plate 28 side falls along the guide plate 28 into the storage container 29a which is waiting below. On the other hand, the aluminum cans not attracted by the permanent magnet 25
2 and falls into the storage container 29b along the guide plate 27 located below.

[0007] In such an empty can processing machine, the fixed compression plate 1
Just by inserting a large amount of empty cans between the second and movable compression plates 13, the loaded empty cans are sequentially crushed by the vibration operation of the movable compression plate 13, and the crushed empty cans are rotated. Since the sorting is performed by the permanent magnets 25 provided, a large amount of empty can processing can be performed in a short time without requiring any manual operation.

[0008]

However, in the above-described conventional empty can processing machine, the movable compression plate 13 is driven by the large and small cams 14 and 15 which are rotated by the driving force of the driving source 16.
By vibrating the whole in small increments, a large number of empty cans that have been introduced are sent out to the side that will be crushed sequentially,
When a large amount of empty cans are pushed up by the tiny vibration of the movable compression plate 13, these empty cans collide with each other,
During empty can processing, there is a problem that it causes noise. Further, as described above, 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 have been input in addition to the weight of the movable compression plate 13 itself. Because there is, drive source 1
There was also a problem that it was necessary to increase the driving force of No. 6.

The present invention has been made in view of such circumstances, and it is possible to extremely reduce the generation of noise caused by collision between empty cans, and to reduce the driving force required for empty can processing. It is an object of the present invention to provide an empty can processing machine that can perform the processing.

[0010]

The empty can processing machine of the present invention comprises:
In order to achieve the above object, a hopper type empty can storage portion provided above the inside of the empty can processing machine main body and storing a large amount of empty cans, and provided below the empty can storage portion and dropped by its own weight An empty can crushing section for crushing the empty can, and an empty can separation mechanism provided below the empty can crushing section and separating the empty can crushed by the empty can crushing section into an iron can and an aluminum can. In the empty can processing machine comprising, at least a part of the side plate of the empty can storage portion performs a rotating operation in conjunction with the crushing operation of the empty can crushing portion, and interlocks with the crushing operation of the empty can crushing portion. Then, a plurality of protrusion members protrude and protrude from a part of the side plate.

[0011]

According to the empty can processing machine of the present invention, when a large amount of empty cans are charged into a hopper type empty can storage portion provided above the inside of the empty can processing machine main body, the charged empty cans lose their own weight. After being dropped by the empty can crushing section and crushed by the empty can crushing section, the iron can and the aluminum can are separated by the empty can separation mechanism. Further, at least a part of the side plate of the empty can storage portion performs a rotating operation in conjunction with the crushing operation of the empty can crushing portion, and a plurality of projections from a part of the side plate in conjunction with the crushing operation of the empty can crushing portion. When the members appear and disappear, the state in which the empty cans stacked in the empty can storage portion are entangled with each other by their respective weights is broken.

Therefore, the operation of breaking the state in which the empty cans are entangled with each other in the empty can storage portion is performed by rotating at least a part of the side plate of the empty can storage portion in conjunction with the crushing operation of the empty can crushing portion. Since the plurality of projecting members are made to protrude and retract from a part of the side plate in conjunction with the crushing operation of the empty can crushing portion, the empty can close to at least a part of the side plate in the empty can storage portion is moved by the plurality of projecting members. Therefore, the noise generated when the empty cans collide with each other is extremely small. In addition, since the operation of breaking the entangled state in the empty can storage portion is sufficient by moving only the empty can that is close to at least a part of the side plate in the empty can storage portion, a large amount of the empty container that has been charged as in the related art is sufficient. It is not necessary to consider the weight of the whole can, and the driving force of the driving source is reduced.

Even if the iron can does not separate, the iron can is separated downward with the movement of the rubber belt 67 by the claw body 63c.

Here, the positional relationship between the slit-shaped discharge hole 54 and the empty can separation mechanism 63A is such that the support shaft 64 is slightly shifted to the left with respect to the discharge hole 54 as shown in FIG. It has been. In addition, the rubber belt 6
The rotation direction of 7 is the counterclockwise direction in FIG.
Thereby, the aluminum can discharged from the discharge hole 54 is not attracted by the permanent magnet 63 and falls to the right in FIG. 4, whereas the iron can is attracted by the permanent magnet 63 and is conveyed to the left in the figure. Therefore, it is possible to separate the aluminum can from the iron can.

A timing belt 68 is wound between the receiving pulley 63b and the driving pulley 57 of the driving 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 rotates, and the wide rubber belt 67 also rotates. Storage containers 69 and 70 are stored in a storage section 71 below the internal frame 60. The storage container 69 stores an iron can, and the storage container 70 stores an aluminum can.

Next, the operation of the empty can processing machine having such a configuration will be described with reference to FIGS. First, with the opening / closing lid 34 provided on the upper part of the empty can processing machine main body 30 opened, empty cans are loaded from the upper part of the empty can processing machine main body 30. The empty cans that have been loaded are hopper type empty can storage units 3.
5 is accommodated. At this time, since each of the side plates 36, 37, 38, and 39 of the empty can processing machine main body 30 is disposed so that the inclination angles thereof are different from each other, the empty can storage portion 35 is provided.
Since the large number of empty cans put in the container are directed in various directions, the empty cans are stored in the empty can storage portion 35 in a state where the entanglement between the empty cans is minimized.

In this state, when the power switch 31 provided on the front surface of the empty can processing machine main body 30 is turned on and then the start button 32 for the processing operation is pressed, the drive motor 55 is driven. When the drive pulley 57 rotates by the drive of the drive motor 55, the circular protrusion 59 is displaced in accordance with the rotation, and the rotation arm 50 is rotated about the shaft 49 as a fulcrum.
When the rotation arm 50 rotates, the crush plate 46 having the lower end attached thereto swings.

When the crush plate 46 swings in the direction approaching the fixed plate 52, the support member 48 provided at the upper end of the crush plate 46 is displaced in the same direction. The lower end of the side plate 36 is pushed up by the displacement operation of the support member 48, so that the side plate 3
6 rotates clockwise. Further, with the displacement operation of the support member 48, the lower end of the turning plate 43 is pushed up, so that the turning plate 43 also turns in the same direction. When the support member 48 is further displaced in the same direction, the stopper piece 47 is engaged with the lower end of the turning plate 43, and in this state, the turning plate 43 is further turned in the same direction. When the crush plate 46 rotates to the position shown by the two-dot chain line in FIG. 4, the rotation of the side plate 36 and the rotation plate 43 stops.

At this time, a plurality of projection members 42 provided on the rotating plate 43 are gradually pushed out from the holes 45 of the side plate 36 with the rotating operation of the side plate 36 and the rotating plate 43. With the slight rotation of the side plate 36, the holes 45 of the respective projecting members 42 are formed.
The state in which the large number of empty cans P accommodated in the empty can accommodating portion 35 are entangled with each other by their own weights is extruded by the extruding operation.

In this state, the empty cans P located between the crushing plate 46 and the fixing plate 52 are respectively reinforced iron plates 51, 53.
Crushed by After the crushing of the empty can P by the crushing plate 46 is completed, the circular projection 59 is displaced in accordance with the rotation of the driving pulley 57, and the rotating arm 50 is swung about the shaft 49 as a fulcrum. When the crush plate 46 swings clockwise due to the swing of the rotating arm 50, the crush plate 46
Moves away from the fixing plate 52. Further, since the pushing force of the stopper piece 47 to the lower end of the rotating plate 43 is released by the swinging of the crush plate 46 in the same direction, 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 rotating plate 43
Are in a state where they do not protrude upward from the holes 45 of the side plate 36.

As described above, the reciprocating operation of each of the protrusion members 42 of the rotating plate 43 from the holes 45 of the side plate 36 and the side plate 3
6, the large number of empty cans P accommodated in the empty can accommodating portion 35 are entangled by the respective weights as much as possible, so that the empty cans P are located in the gap between the crush plate 46 and the fixed plate 52. Sent out in order.

On the other hand, when the empty can P crushed by the swinging operation of the crushing plate 46 falls by its own weight from a slit-shaped discharge hole 54 provided at the lower end of the crushing plate 46 and the fixed plate 52, It moves to the empty can separation mechanism 63A waiting downward. On the side of the empty can separation mechanism 63A, the driving force of the driving motor 55 is given to the receiving pulley 63b via the timing belt 68, and the driving force causes the rotating body 63a to rotate, and via the wide rubber belt 67. The roller body 65 also rotates.

When the empty can P falls on the circular permanent magnet 63 attached to the rotating body 63a of the empty can separation mechanism 63A, the aluminum can slides on the wide rubber belt 67 and falls to the storage container 70 side. On the other hand, the iron can has a permanent magnet 6
By being attracted by 3, it is drawn in a counterclockwise direction in FIG. Since the iron can is attracted to the permanent magnet 63 via the wide rubber belt 67, the iron can
When it moves to the fifth side, the attraction force of the permanent magnet 63 is released, so that it falls into the storage container 69 by its own weight.

At this time, if the iron can does not separate from the rubber belt 67 due to the attraction force of the permanent magnet 63, the claw 63c provided on the rubber belt 67 is used to scrape the iron can downward beyond the attraction force of the permanent magnet 63. It is. As described above, in the present embodiment, when a large amount of empty cans P are loaded into the hopper type empty can storage unit 35 provided above the inside of the empty can processing machine main body 30, the loaded empty cans P are removed. By its own weight, it falls to the side of the can crushing section composed of the crushing plate 46 and the fixed plate 52, is crushed by the can crushing section, and is separated into an iron can and an aluminum can by the can separating mechanism 63A. In addition, by rotating at least a part of the side plate of the empty can storage portion 35 in conjunction with the crushing operation of the empty can crushing portion, the side plates are stacked in the empty can storage portion 35, and a state in which they are intertwined by their respective weights. Collapsed.

Therefore, the operation of breaking the entangled state in the empty can storage portion 35 is rotated in conjunction with the crushing operation of the empty can crushing portion at least a part of the side plate of the empty can storage portion 35. Therefore, only the empty cans P adjacent to at least a part of the side plate in the empty can storage portion 35 are moved, so that noise generated when the empty cans collide with each other is extremely small. Further, the operation of breaking the entangled state in the empty can storage portion 35 is sufficient by moving only the empty can P close to at least a part of the side plate in the empty can storage portion 35. There is no need to consider the weight of the entire large number of empty cans, and the driving force of the driving motor 55 as a driving source is reduced.

[0032]

As described above, according to the empty can processing machine of the present invention, the operation of breaking the entangled state in the empty can storage portion is performed by at least a part of the side plate of the empty can storage portion. Since the rotating operation is performed in conjunction with the crushing operation of the crushing portion and the plurality of projecting members are protruded and retracted from a part of the side plate in conjunction with the crushing operation of the empty can crushing portion, Since only the empty cans adjacent to at least a part of the side plate are moved by the plurality of projecting members, the noise generated when the empty cans collide with each other can be extremely reduced. In addition, since the operation of breaking the entangled state in the empty can storage portion can be performed by moving only the empty can close to at least a part of the side plate in the empty can storage portion by a plurality of projecting members, the operation is performed as in the related art. It is not necessary to consider the weight of the entire large number of empty cans, and the driving force of the driving source can be reduced.
