DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can collection process capable of automatically separating a magnetic can and a non-magnetic can, that is, a steel can and an aluminum can, after crushing an empty metal can into a flat shape. About the machine.

[0002]

2. Description of the Related Art Conventionally, various devices for flat crushing and collecting empty metal cans such as canned beverages have been provided on the market. In particular, aluminum cans having high reusable value are made of other metal cans. It is very preferable to perform separation / sorting with cans in a later recycling process. As a device for sorting / separating cans, for example, a can processing machine 50 as shown in FIG. 4 is known. I have.

[0003] This is an empty can from the inlet 51
The magnets 52 are held one by one by the ascending conveyor 53 and transferred, and the magnets linked to this conveyor 53 at the top thereof
By 54, first, the non-magnetic aluminum can 52 is taken out of the conveyor 53 by falling by its own weight, sent to the aluminum can compression section 55 through a gutter, and the magnetic steel can 52
Is held by the conveyor 53 by the attraction force of the magnet 54, and is further transported.When reaching the non-attached portion of the magnet 54, separation is performed by its own weight drop at the magnetic force release position, It is sent to the compression section 56 for steel cans and is subjected to processing such as pressing.

However, since this apparatus is configured to sort and separate a steel can and an aluminum can in advance before the can is crushed, the steel can is supplied in a normal state in which the outer shape of the can is not damaged. At this time, the can is transferred to a desired position by the attraction force of the magnet, but a deformed can, that is, a steel can that is depressed or distorted in outer shape, has the magnet attached to the can. Does not work well, and its suction surface has a very small contact area with the can, so it is separated from the conveyor without the suction force to hold it in the can. Since it is mixed in the compression section, inconvenience occurs in a later recycling step.

In addition, a plurality of compression units and conveyors are required, so that the apparatus is increased in size and cost, and cannot be easily installed and used near buildings in towns and vending machines for canned drinks. And other various problems.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and comprises a can compressing means corresponding to a lower side of a can input section and a can selecting means. The sorting means has a compact structure by attaching an inclined disk to the support shaft of the fuselage at the falling position of the crushed can and arranging an annular magnet behind the disk to suck and hold the crushed magnetic can. Accordingly, it is an object of the present invention to provide a can collection processor capable of easily and automatically sorting and separating a steel can and an aluminum can which are randomly inputted and crushed.

[0007]

Means of the present invention for achieving the above object is to provide a can input portion provided on the upper part of the fuselage and a flat can corresponding to the lower side of the input portion. Compressing means for crushing and dropping to the lower part, and sloping and rotatably provided at the falling position of the crushed can, sliding the non-magnetic can to one side, adsorbing and rotating the magnetic can to drop to the other side A sorting disk, which is rotatable in one direction by a driving device to a spindle supported by the fuselage, and a tilted disc attached at a low point on the slope corresponding to the falling position of the can. An annular magnet provided on the back side of the inclined disk to adsorb and hold the crushed magnetic can, and detaching means for linking the inclined disk to detach the adsorbed and crushed can from the disk surface. It is in the configuration of the can collection processing machine.

[0008]

The present invention configured as described above has the following effects.

The metal empty cans randomly supplied to the charging section are crushed flat by compression means and sent to the lower part.

Then, the crushed can falls on a low surface of the inclined disk continuously rotated at a predetermined speed from the end of the compression means. When the crushed can is an aluminum can, the crushed can is inclined. Since it is not affected by the magnetism of the annular magnet disposed on the back side of the disk, it slides down by its own gravity along the inclination of the disk and is collected in the aluminum can pool.

On the other hand, when the crushed can is a steel can,
As soon as the player falls on the inclined disk and gets on it, the disk is immediately affected by the magnetism of the disk and is attracted and held on the disk surface against the inclination.

Therefore, as the disk rotates, the crushable can is turned from a low place to a high place and further to a low place to make a detour, and the crushed can which has reached the low place again is separated from the inclined disk. By means, the can is separated from the board surface against the attraction force of the magnet or with the attraction force being gradually reduced, so that the can slides down the slope and is collected in the steel can pool.

By the above operation, the metal crush can is
The magnetic can and the non-magnetic can are automatically sorted and separated by the sorting means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a can recovery processing machine according to the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral A denotes a can collection processing machine, which randomly empty metal cans b such as canned beverages, for example, aluminum cans b as non-magnetic cans and steel cans b as magnetic cans. After crushing, these aluminum can b and steel can b
An apparatus for separating and collecting the cans, and an input section 1 for cans b;
It is basically constituted by the compression means 2 and the selection means 3.

The charging section 1 is connected to a charging port 5 at an upper portion of a body 4 formed in a box shape or the like, and is formed in a funnel shape which is narrowed down and extends downward. A charging path 6 is formed, one by one being sequentially fed downward.

The compression means 2 is for crushing the can b in a flat shape corresponding to the lower side of the charging section 1 and then dropping it to the lower part. (Right and left) A plurality of stages, for example, three stages of pressure rolls 7, 7, 8, 8, 9, 9 are supported by a rotating shaft 1
The rolls are arranged so as to gradually narrow as they go downward by 0, 10, and 11, 11 and 12, and are configured to be rotated at a predetermined speed by a driving member 13 described later. When the crushed can b reaches the lowermost stage, the pressing rolls 9 bring the final flat state.

The peripheral surfaces of the pressing rolls 7, 7 and 8, 8 and 9, 9 are provided with a large number of spaced-apart radially projecting ridges.
14, 14 and 15, 15 and 16, 16 are added to improve the crushing effect of the can b.

The rotary shafts 11 and 12 are provided with a retreating means 17 for preventing an excessive load on the driving member 13 caused by an excessive supply of the can b or a crushing failure due to mixing of foreign matter. And, at all times, ammunition to Axis 18, 19 of body 4
The rotating shafts 11, 12 are elastically attached by the 20, 21 so that the input path 6 is formed.
When an excessive load is applied to the shaft, the turning path 6 is pivoted outward around the pivots 18 and 19, so that the charging path 6 is largely opened and the circulation of the can b is facilitated.

The driving member 13 drives the motor 22 with a speed reducer by a chain 23 and an interlocking gear 24.
In the direction indicated by the arrow in FIG.
And 12,12, that is, the pressing rolls 7,7 and 8,8,9,
9 is continuously rotated.

The sorting means 3 is provided so as to be rotatable and inclined at the falling position of the can b crushed by the compressing means 2, so that the non-magnetic can b slides down to one side and the magnetic can b is adsorbed. Swivel and drop to the other side.
, A magnet 26, and a separation unit 27.

Of these, the inclined disk 25 is formed of a nonmagnetic material such as stainless steel or synthetic resin into a circular shape slightly larger than the pressing rolls 7, 7, 8, 8, 9, 9, 9 and has an inclined surface. , That is, the support shaft that is supported by the body 4 with the receiving position 28 corresponding to the falling position of the can b.
A receiving means 28 is rotatably mounted in one direction by a driving means 30 to the receiving position 29. The receiving position 28 is biased toward a center position on the rotation direction side below the inclined disk 25 divided into four equal parts.

Although not shown, the drive means 30 uses a motor which is directly or indirectly linked to the support shaft 27 of the inclined disk 25 supported by the body 4, as shown in FIG. As described above, the friction wheel 33 fixed to the output shaft 32 of the motor 31 is pressed against the outer peripheral edge of the inclined disk 25, and the inclined disk 25 is rotated by friction driving by rotation of the friction wheel 33. .

The magnet 26 is fixed to a support plate 34 attached to the body 4 by providing a gap on the back side of the inclined disk 25 on the upper surface of the disk 25 so as to give an attractive force to the can b. The crushed magnetic can b (steel can) is sucked and held at the receiving position 28 by arranging two pieces in a series of annular shapes with different polarities near the outer periphery of the inclined disk 25. With the rotation of the inclined disk 25, the steel can b thus turned pivotally moves from a low position to a high position, and then turns to a low position by reversing, and the other side of the receiving position 28, that is, the steel can The aluminum can b, which does not receive the magnetic force of the magnet 26 until it is transferred to the can b until it is transported to the delivery position 35 of the b, slides down from the inclined disk 25 at the receiving position 28. At the bottom of the aluminum can 36 It is recovered Te.

Although not shown, a large number of magnets 26 formed in a small circular or rectangular shape may be fixed to the support plate 34 in such a manner that the magnets 26 are continuously brought close to each other.

The separating means 27 separates the crushed can b sucked and held in association with the inclined disk 25 from the disk surface. As shown in FIG. 3, a magnet provided on the back side of the inclined disk 25 26 at a low point of inclination, and
Is gradually separated from the back surface of the inclined disk 25 as approaching the delivery position 35, whereby the magnetic force acting on the inclined disk 25 is gradually reduced. In order to attenuate the magnetic force of the magnet 26, the amount of the magnet 26 may be gradually reduced, or the polarity of the NS pole may be made the same at the position.

In the case shown in FIGS. 1 and 2, a guide 37 of a substantially b-shaped can b is attached to the body 4 above the inclined disk 25, and the magnet
If the upper surface of the magnet 26 is provided uniformly at the same interval with respect to the back surface of the disk 25 in the mounting mode of the disk 25, the magnet 26 detours upward from the receiving position 28 of the can b and reaches the sending position 35 on the other side. It receives a uniform magnetic force.

Therefore, at the delivery position 35, the movement of the can b is restrained by the guide plate 37 against the rotation of the inclined disk 25, whereby the can b contacting the guide plate 37 is scraped off. , Are collectively collected in a steel can pool 38 installed below the delivery position 35.

The guide body 37 also has a function of accurately guiding the aluminum can b falling from the compression means 2 to the aluminum can reservoir 36.

In FIG. 1 and FIG. 2, reference numeral 39 denotes a guide plate of a crushing can b provided between the compression means 2 and the sorting means 3, and the guide plate 39 moves to the receiving position 28 of the inclined disk 25 in the sorting means 3.
The crushing can b is made to fall smoothly.

[0031]

The present invention having the above-described structure has a simple structure in which the means for sorting the crushed cans is provided at the lower part of the compression means at the dropping position of the crushed cans. It can be installed easily even in a small space such as a city.

In particular, since the sorting of steel cans and aluminum cans is performed after the crushing of the cans, the cans are sufficiently flat and the contact area of the sorting means with the inclined disk is as large as possible. And the magnetic force of the magnet acts sufficiently on the crushed can, preventing the steel can from being mixed into the aluminum can due to mis-suction and holding, and improving the yield of highly reusable aluminum cans. Significantly improved. And so on.
