BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a roll type empty can crusher.

[0002]

2. Description of the Related Art Roll type empty can crushers to which the present invention is applied are disclosed in Japanese Utility Model Laid-Open Nos.
No. 142767 is known. In particular, the latter is equipped with a magnet roll for separating a magnetic material (steel product) and a non-magnetic material (aluminum product) in the empty can.

[0003]

However, in the former Japanese Utility Model Application Laid-Open No. 51-33876, the empty can (12) rolls down the drop passage (14) and is rolled upside down in the horizontal position. (2a) and (3a), the cylindrical core wire of the empty can (12) and all rolls (2a).
a) The rotation axes of (3a), (2b), (3b), (2c), and (3c) are in parallel.

In addition, the rolls (2a) (3a) (2b)
(3b) The same convex ridge (15) is engraved on the body surface of (2c) and (3c), and the form of the convex ridge (15) is merely a simple isosceles triangle. Absent. That is, the ridge (15) only increases the friction coefficient, and the rolls (2a) (3a) (2b) (3b) (2c)
In consideration of the rotation direction of (3c), it is not sharply curved only in the feed direction as in the so-called stopping claw wheel, and does not apply a pulling force or a wedge action force to the empty can (12).

[0005] Therefore, the empty can (12) that has naturally rolled down from the drop passage (14) to between the two rolls (2a) and (3a) at the uppermost position, initially has the two rolls (2a) and (3).
In a state of being laid on the ridge (15) of the b), a dance phenomenon such as being accompanied by the two rolls (2a) and (3b) and spinning is generated, and it is not quickly and reliably drawn. In particular, since the steel product is hard, the steel product does not bite into the ridge (15) reliably and stably, and the above-mentioned problem becomes remarkable.

In order to apply a compressive force to the empty can (12), the uppermost rolls (2a) and (3b) are arranged in parallel at a fixed interval smaller than the diameter of the empty can (12). It is necessary, but if the certain interval is made too narrow, the above-mentioned dancing phenomenon of the empty can (12) becomes more intense and it becomes difficult to pull in the same. Must be set to Then, the number of stages until the empty can (12) is squashed into a flat plate increases, so that a large number of rolls are required and the machine itself must be enlarged.

On the other hand, the latter Japanese Utility Model Application Laid-Open No. 52-142767 has the same problem as described above because it is a charging system in which an empty can is rolled down. However, in the latter case, the crescent-shaped grooves (D) and (D) are formed on the body surfaces of both rolls (4) and (5) at the uppermost position.
And the claws (G) and (G), it can be said that it is easier to bite into the body surface of the empty can compared to the configuration of the above-mentioned known invention.

However, for that purpose, both rolls (4)
(5) must be accurately rotated synchronously to keep the grooves (D) and (D) symmetrical with each other. If the left and right pairs of the claws (G) and (G) do not bite into the empty can at once, the empty can inevitably causes a rolling phenomenon such as rolling, and in that sense, it is difficult to design the motion mechanism. Restrictions.

Furthermore, in the latter case, the magnet roll (1
6) is also equipped, but it is all rolls (4) (5)
(6) The diameter is much smaller than (7), (8) and (9), and the body surface is located at an eccentric position retreated to one of right and left from the vertical line of the falling of the empty can.

Therefore, the lowermost roll (8)
An empty can of magnetic material (steel product) falling from (9)
It is practically impossible to stably adsorb the magnet roll (16) to the body surface of the magnet roll (16) without leaking, and it is inferior in the effect of sorting the non-magnetic material (aluminum product). The contact area between the empty cans are from significantly small again.

[0011]

SUMMARY OF THE INVENTION The present invention is intended to solve such a problem. For this purpose, an empty can input shot opening on the upper surface of the machine housing and a vertical drop of the empty can falling from the input shot are provided. A pair of left and right large primary pressure rolls mounted on the upper position in the machine casing in a parallel state sandwiching the wire, and the primary pressure rolls in a parallel state sandwiching the falling vertical line of the empty can. And a pair of left and right small secondary pressure rolls mounted on a lower position of the second pressure roll and a lower pressure position of the secondary pressure roll paralleled to the lower position of the secondary pressure roll in order to select a magnetic material empty can and a non-magnetic material. With a single magnet roll,

The pair of left and right primary pressure rolls is maintained at a constant interval smaller than the diameter of the empty can, while the pair of left and right secondary pressure rolls is further narrower than the constant interval of the primary pressure rolls. While maintaining a constant interval, the above-mentioned primary and secondary pressure rolls and magnet rolls are driven by a single drive motor.
The empty can is driven to rotate in the feeding direction adapted to the falling of the empty can, and the empty can is crushed into an automatic stepped flat plate by a primary or secondary pressure roll having a difference in diameter. In a roll-type empty can crusher that separates into magnetic and non-magnetic materials by the magnetic force of the net roll,

[0013] A pair of left and right transmission gears that can be engaged with each other and are identical to each other are fixed on the respective rotating shafts of the primary and secondary pressure rolls. Between one of the transmission gears and the upper and lower one of the left and right transmission gears in the secondary pressure roll, a rotational power distribution gear from the drive motor is interposed in a meshing state,
A rotating power take-out chain or belt is wound between the upper and lower sides of one of the left and right rotation spindles of the secondary pressure roll and the rotation spindle of the magnet roll,

[0014] The empty can is put in the empty can for one or two empty cans.
The lower end of an empty can that is set upright on the upper surface of the above-mentioned casing so as to be able to fall along the vertical line of its fall while maintaining an upright posture orthogonal to the next pressure roll, and falling under the upright posture A large wedge claw sharply curved into a beak that can bite into the edge portion and be pulled in quickly, and is roughly cut into the body surface of the large-diameter primary pressure roll,

[0015] As a continued shut seizing engagement to the primary flat surface of the cans by the primary pressure roll, a sharp curved with a small Kusabitsume the beak of a can pull this, the diameter small secondary pressure roll finely engraved on cylinder surface, turned into further in diameter larger than the primary pressure roll the mug the net roll, the empty cans drop
While eccentric in the horizontal direction by a certain amount from the lower vertical line,
By allowing the body surface to block the falling vertical line of the empty can, the empty can of the above magnetic material is adsorbed to the magnet roll in a receiving state, while that of the non-magnetic material is laterally moved by the magnet roll. It is characterized in that it is determined to fly off.

[0016]

According to the above construction of the present invention, the empty can input shot is set upright on the upper surface of the machine casing so that the empty can can fall along the vertical line of its fall in the upright posture. A large wedge claw sharply curved into a beak shape that can bite into the lower edge of the empty can that falls in the upright posture and pull it in quickly is attached to the body surface of the large primary pressure roll. While being roughly engraved, the primary press roll continuously bites and locks the primary flat surface of the empty can, and the small wedge nail that is sharply curved into a beak shape that can be pulled in is pressed into a small secondary press. Since it is finely engraved on the body of the roll, the empty cans falling from the charging shout can be quickly and reliably drawn and pinched by the primary pressure roll, and crushed into a primary flat state. There is no risk of a rolling phenomenon.

At this time, the large wedge claw engraved on the body surface of the primary pressure roll has a sharply curved beak shape in a feed direction in which an empty can can be pulled in, and acts as a stopping claw wheel. its primary pressure roll is Te and durable large diameter products <br/>, I rotational peripheral speed of the fast Ikoto with or mutually俟, cans Suva
And phrases can be pressed surely draw today, nor emit a loud noise.

Also, the wedge claw engraved on the body surface of the secondary pressure roll has a sharply curved beak shape in the feed direction capable of pulling in an empty can, and is finely engraved as a small one. securely attached eating into flat surfaces has been turned into a wrinkling states of the cans by the primary pressure roll, I late have peripheral speed with phase俟the secondary pressure roll can be pressed strength Ku pull clamping, It can be crushed smoothly as the final flat plate shape.
Two stages of upper and lower secondary pressure rolls are sufficient, which is very useful for reducing the processing speed and reducing the size and size of the entire machine.

Further, a magnet roll for separating an empty can of a magnetic material (steel product) from that of a non-magnetic material (aluminum product) is further enlarged in diameter than the above-mentioned primary pressure roll. Moreover, since the barrel surface of its is faced to the positional relationship of blocking falling vertical line cans, the cans of magnetic material slowly falling from the flat plate shape crushed by the secondary pressure roll, its contact area Extremely large and the rotating peripheral speed of the magnet roll can be stably adsorbed and held in a reliable receiving state on the body surface of the slowest rotating peripheral speed. On the other hand, an empty can made of non-magnetic material is once received by the body surface of the magnet roll, Since it can be surely separated in the eccentric lateral direction, it can be remarkably excellent in its sorting effect.

The primary and secondary pressure rolls are also used as a transmission mechanism for rotating the primary and secondary pressure rolls and the magnet roll by a single drive motor in a feed direction adapted to the dropping of the empty can. A pair of left and right transmission gears that can be engaged with each other and are identical to each other are engraved on each of the rotary shafts, and either the left or right transmission gear of the primary pressure roll and the secondary pressure roll The rotational power distribution gear from the drive motor is interposed between the upper and lower one of the right and left transmission gears in a meshing state, and either the left or right rotation support shaft of the secondary pressure roll and the magnet roll Since the chain or belt for taking out the rotational power is wound between the upper and lower rotating shafts, the above-mentioned transmission mechanism can be significantly simplified. Tsuhoka, it also compatible phase 俟 of the transmission gear with the same size and shape, it is significantly advantageous in mass production effect as maintenance and inspection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The specific structure of the present invention will be described below in detail with reference to the illustrated embodiment. In FIGS. 1 and 2 showing the entire roll type empty can crusher, (10) is a rectangular parallelepiped casing. On the upper surface thereof, an empty can input short (11) is installed in an upright state. The charging shutter (11) has a guide function of allowing the empty can (M) to fall along its vertical line (HH) under an upright posture perpendicular to the first and second pressure rolls described later.

(12a) and (12b) are vertical lines (H-) of the empty cans (M) which fall from the charging shutter (11).
H) are a pair of left and right primary pressure rolls rotatably mounted on an upper position in the machine housing (10) in a parallel state sandwiching H), and are smaller than the diameter (D) of the empty can (M). By maintaining the constant interval (W1), the body surface of the empty can (M) is received and pressed, and the semi-finished product (M1) having a certain thickness (T) as shown in FIG. Primary flattening. The semi-finished product (M1) is still in a hollow state in which the body surface does not adhere.

(13a) and (13b) are also in a parallel state sandwiching the falling vertical line (HH) of the empty can (M).

The magnet roll (14) is also wound between the upper and lower parts, and is also rotated in the feed direction (F) by the drive motor (22).

The primary and secondary pressure rolls (12a) (12)
b), (13a), and (13b) have the following relations between them. That is, the primary pressure rolls (12a) and (12b) are
3b) are dimensioned in diameter larger than, based on its relatively not fast peripheral speed and the wide predetermined interval (W1), with pressure quickly securely clamping the empty cans (M), the noise generated when the (Shock noise) is suppressed to a small level.

In addition, the primary pressure roll (12a)
On the body surface of (12b), large wedge claws (31a) and (31b) sharply curved in a beak shape in the feed direction (F) are engraved in a parallel extending state along the axial direction. With the sharply curved toe in the feed direction (F), the lower end edge of the empty can (M) falling along the vertical line (H-H) from the above-mentioned input shout (11) is quickly bitten and locked,
This can be reliably pulled in.

On the other hand, the secondary pressure rolls (13a) (13)
Small wedge claws (32a) (32b) sharply curved in a beak shape in the feed direction (F) are also finely engraved on the body surface of b) in a parallel extending state along the axial direction thereof.
The sharply curved toe bites and engages the wrinkled flat surface of the primary crushed semi-finished product (M1), and engages it with the primary pressure rolls (12a) (12).
Based on the Slow peripheral speed than b), which is to ensure that retract so.

Further, the magnet roll (14) is
The diameter is larger than the next pressure rolls (12a) and (12b). Based on its slowest peripheral speed and large contact area, the magnetic material empty can (M), which is the final product (M2), can be reliably formed. While being stably sucked and held in the receiving state, the non-magnetic material can be slowly and surely bounced laterally by the body surface of the magnet roll (14) to improve its sorting performance.

During the installation and use of the empty can crusher, when the empty can (M) is put in from the empty can input shot (11) of the casing (10), the empty can (M) becomes 1
It is drawn between the next pressure rolls (12a) and (12b) and receives a primary squeezing action to form a semi-finished product (M1) as shown in FIG. It is flattened until (T).

At this time, as shown in FIG. 3 (A), the empty can (M) has its cylindrical core line of the primary and secondary pressure rolls (12a) (1) due to the guiding action of the charging shutter (11).
2b) (13a) (13b) It is kept in an upright posture and falls along the falling vertical line (HH), so that the empty can (M) does not have a fear of causing a rolling dance phenomenon.
3B, rough large beak-shaped wedge claws (31a) and (31b) of the primary pressure rolls (12a) and (12b) are provided at the lower end edge of the roller.
As soon as possible, it is securely fastened and locked, and its wedge claws (31
a) If it says (31b), it will be pulled in quickly as a control pawl.

In addition, the primary pressure rolls (12a) (12a)
b) is large in diameter, its rotational peripheral speed is high and rough
To have large beak-shaped wedge claws (31a) (31b)
The, hardly occurs the seizing locking mistake, and even the cans (M) is hard steel product (magnetic), without losing thereto, be nipping pull the cans quick (M) is Ku You can. In the case of an aluminum product (non-magnetic material), there is no separate lid at the bottom, so the diameter is not as large as the lower edge of the steel product, but the bottom is formed thinner than the body surface. Also, since it is softer than steel products, if it is dropped in its standing position, it will fit between the primary pressure rolls (12a) (12b) that keep a wide constant interval (W1), and will be securely inserted. , And the pressure is applied.

Thereafter, the semi-finished product (M1) is passed on to the secondary pressure rolls (13a) (13b), and the secondary pressure action by the secondary pressure rolls (13a) (13b) is performed. However, since the flat surface of the semi-finished product (M1) is in a wrinkled state, the secondary pressure roll (13a)
(13b) Fine and small beak-shaped wedge claws (32a) (32
b), the semi-finished product (M1) is securely bite-engaged with the flat surface of the semi-finished product (M1), and the wedge claws (32a) and (32b) are also used as stopping pawls to form the secondary pressure roll (13a). ) (13
By late have peripheral speed of b), can be pressed stably good Ku pull clamping, the final product as shown in FIG. 4 (B) to茲(M2)
As a result, the plate is flattened into a plate shape in which the body surface is in close contact.

Since the two-stage crushing operation is performed on the falling vertical line (HH) of the empty can (M), its own gravity can be effectively utilized, and the first and second pressure rolls ( The semi-finished product (M1) is converted to the final product (M2) by the difference in rotational peripheral speed between 12a, 12b, 13a, and 13b.
The empty can (M) crushed into
(14), it can be dropped slowly, so that the overall processing efficiency and the first and second pressure rolls (12a)
The durability of (12b), (13a) and (13b) can be significantly increased.

Then, the secondary pressure roll (13a)
Since the largest magnet roll (14) also faces the lower position of (13b), the final product (M2) after being crushed as described above is the magnet roll (14).
The magnetic material (steel product) is slowly dropped on the body surface of the magnet roll, and the magnetic material (steel product) is magnetized based on the low rotational peripheral speed and large contact area of the magnet roll (14). (14) The magnetic material collection box (1) is stably sucked and held on the magnetic material collection box (1) immediately below the rotation.
It is dropped and collected to 5). (33) shows the stopper for releasing the container, and it goes without saying that the stopper stops and falls into the collection box (15) upon hitting the stopper.

On the other hand, the above non-magnetic material (aluminum product)
Cans of (M) is also falls onto the barrel surface of the mug the net roll (14), which is spun off the I <br/> Riyukkuri and laterally the body surface that without its being adsorbed, Partition shot (1
Through the guide action of 6), the collection box for magnetic material (1)
It is dropped and collected into the collection box for non-magnetic material (17) in parallel with 5), and is separated by material by itself.

And sealed subsequently with eating engaging the primary flat surface of the cans (M) by a sharp curve in the beak of a can pull the small Kusabitsume (32a) (32 b) which, the smaller diameter second pressure roll ( 13a) and (13b) are finely carved on the body surface, and the magnet roll (14) is replaced with a primary pressure roll (12a).
(12b) further in diameter larger turned into and than, the empty cans (M)
Deviates laterally by a fixed amount (X) from the falling vertical line (HH)
While keeping in mind, the body surface is the falling vertical line of the empty can (M)
By face the (H-H) such that the blocking, while adsorbing the state receiving the magnetic cans (M) is to mug the net roll (14), it mug the net roll a non-magnetic material (14) is set so as to jump in the horizontal direction, so that there is an effect that all the problems of the well-known device described at the beginning can be improved.

That is, according to the configuration of the present invention, the empty can (S) can be dropped along the falling vertical line (HH) of the empty can (M) in the upright posture. It is set upright on the upper surface of the machine case (10), bites into the lower end edge of the empty can (M) that falls under its standing posture, locks quickly, and is sharply shaped like a beak that can be pulled in. The curved large wedge claws (31a) and (31b) are roughly engraved on the body surface of the large-diameter primary pressure rolls (12a) and (12b), and are formed by the primary pressure rolls (12a) and (12b). Continue to bite and lock the primary flat surface of the empty can (M),
