Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, various flat metal crushing apparatuses for collecting and crushing empty metal cans, such as canned beverages, have been provided on the market. Especially, aluminum cans of high reusability are made of other metal cans. It is extremely preferable to separate and sort the cans in the subsequent recycling process, and as a device for sorting and separating the cans therefor, for example, a can processor 50 as shown in FIG. 4 is known. There is.

This is an empty can inserted from the inlet 51.
The magnets 52 are held and transferred one by one by the ascending conveyor 53, and the magnets are linked to the conveyor 53 at the top thereof.
First, the non-magnetic aluminum can 52 is taken out from the conveyor 53 by its own weight by the 54 and sent to the compression unit 55 for the aluminum can through the gutter.
Is to be further carried while being held on the conveyor 53 by the attraction force of the magnet 54, and when it reaches the non-attachment portion of the magnet 54, the magnetic force releasing position causes separation due to its own weight drop, It was sent to the compression unit 56 for steel cans and subjected to processing such as pressing.

[0004] However, since this device has a structure in which a steel can and an aluminum can are sorted and separated in advance before the can is crushed, a steel can in a normal state in which the outer shape of the can is not damaged is supplied. In this case, the attraction force of the magnet acts to move the can to a desired position. However, a deformed can, that is, a steel can that is dented or distorted in its outer shape is In addition to its insufficient suction force, its suction surface also has a very small line contact area with the can, so it can be separated from the conveyor without the suction force to hold it in the can. Since it mixes in the compression part, inconvenience occurs in the subsequent recycling process.

Further, since a plurality of compression units and conveyors are required, the apparatus becomes large and the cost becomes high, and it cannot be easily installed and used in the vicinity of buildings and vending machines for canned drinks in the city. There were various problems such as.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and comprises a can compressing means and a can selecting means corresponding to the lower side of the can feeding section. The selecting means has a compact structure by attaching an inclined disk to the support shaft of the machine body at the falling position of the crushing can and disposing an annular magnet for attracting and holding the crushed magnetic can on the back side of the disk. Thus, it is an object of the present invention to provide a can collecting and processing machine that can easily and automatically sort and separate steel cans and aluminum cans that are randomly charged and crushed.

[0007]

The means of the present invention for achieving the above-mentioned object is to flatten the can in correspondence with the can input portion provided on the upper part of the machine body and the lower side of the input portion. The crushing means is dropped into the lower part and the crushed can is installed in a tilted and rotatable manner at the dropping position, the non-magnetic can slides down to one side, the magnetic cans adsorb and swirl down to the other side. The sorting means comprises a sorting means, which is rotatable in one direction by a driving means to a support shaft supported by the machine body, and which has a tilted disc attached so that a low point in the tilt corresponds to a drop position of the can. An annular magnet provided on the back side of the inclined disc for adsorbing and holding the crushed magnetic can, and a detaching means for releasing the crushed can adsorbed and held in association with the inclined disc from the disc surface. It is in the configuration of the can collection processor.

[0008]

The present invention having the above-described structure has the following functions.

The empty metal cans randomly supplied to the charging part are flattened by the compression means and sent to the lower part thereof.

Then, the crushed can drops from the end of the compression means onto the lower surface of the inclined disk that is continuously rotated at a predetermined speed. If the crushed can is an aluminum can, the can is inclined. Since it is not affected by the magnetism of the annular magnet arranged on the back side of the disk, it slides down along the inclination of the disk by its own gravity and is recovered in the aluminum can reservoir.

On the other hand, when the crushing can is a steel can,
When the vehicle falls on the inclined disk and gets on the disk, it is immediately affected by the magnetism of the magnet in the disk, and is attracted and held on the disk surface against the inclination.

Therefore, as the disc rotates, the disc circulates from the low place to the high place and then to the low place to make a detour movement. When the crushed can reaches the low place again, the crushed can is separated from the inclined disc. By the means, the can is separated from the board surface against the attracting force of the magnet or by gradually reducing the attracting force, so that the can slides down along the slope and is collected in the steel can reservoir.

By the above operation, the metal crush can is
The sorting means automatically sorts and separates magnetic cans and non-magnetic cans.

A charging path 6 is formed in which the respective pieces are sequentially fed downward.

The above-mentioned compression means 2 corresponds to the lower side of the charging section 1 and crushes the can b into a flat shape, and then drops it into the lower part. (Left and right) a plurality of stages, for example, three stages of pressure rolls supported by a pair, such as three stages of pressing rolls 7,
The rolls 0, 10 and 11, 11 and 12, 12 are arranged so that the distance between the rolls gradually narrows downward, and the rolls are rotated at a predetermined speed by a drive member 13 described later. When the crushed can b reaches the lowermost stage, the pressing rolls 9 and 9 bring the final flat state.

It should be noted that a large number of radially projecting ridges are formed on the peripheral surface of the pressing rolls 7, 7 and 8, 8 and 9 and 9 at intervals.
14, 14 and 15, 15 and 16, 16 are attached to improve the crushing effect of the can b.

Further, a retracting means 17 is attached to the rotating shafts 11 and 12 in order to prevent an excessive load on the driving member 13 caused by a crushing failure due to excessive supply of the can b or mixing of foreign matter. So, at all times, ammo to the pivots 18 and 19 of the fuselage 4
The rotary shafts 11 and 12 are elastically attached by 20 and 21 so that the charging path 6 is formed.
When an excessive load is applied to the cans b, they are pivoted outward about the pivots 18 and 19, so that the charging passage 6 is largely opened and the cans b are easily distributed.

The drive member 13 drives the motor 22 with a reduction gear by a chain 23, an interlocking gear 24, etc.
In the direction shown by the arrow in FIG. 1, the rotating shafts 10, 10 and 11, 11
And 12,12, that is, pressure rolls 7,7 and 8,8 and 9,
9 is continuously rotated.

The above-mentioned selecting means 3 is rotatably provided in an inclined shape at the dropping position of the can b crushed by the compressing means 2, the non-magnetic can b is slid to one side, and the magnetic can b is adsorbed. The tilted disc 25
And a magnet 26 and a detaching means 27.

Of these, the inclined disc 25 is formed of a non-magnetic material such as stainless steel or synthetic resin into a circular shape slightly larger than the pressure rolls 7, 7 and 8, 8 and 9, 9 and the inclination thereof is increased. At a low position, that is, the receiving position 28 corresponds to the dropping position of the can b, and the supporting shaft is supported by the machine body 4.

Although not shown, the driving means 30 may be a motor directly or indirectly linked to the spindle 27 of the inclined disk 25 supported by the machine body 4, as shown in FIG. As described above, the friction wheel 33 fixed to the output shaft 32 of the motor 31 is brought into pressure contact with the outer peripheral edge of the inclined disk 25, and the inclined disk 25 is rotated by frictional driving by the rotation of the friction wheel 33. .

The magnet 26 is fixed to the support plate 34 attached to the machine body 4 on the back side of the inclined disc 25 with a space provided on the upper surface of the disc 25 so as to give a suction force to the can b. The magnetic can b (steel can) that is crushed is adsorbed and held at the receiving position 28 by arranging two of them in a series of annular shapes with different polarities toward the outer circumference of the inclined disk 25. The formed steel can b is swung from the low position of the slope to the high position of the slope and further swung from the low position of the slope to the low position with the rotation of the inclined disk 25. The aluminum can b which exerts an attractive force on the can b until it is conveyed to the delivery position 35 of b, and which is not affected by the magnetic force of the magnet 26, slides down from the inclined disk 25 at the receiving position 28.

Is gradually separated from the back surface of the inclined disc 25 as it approaches the delivery position 35, the magnetic force acting on the inclined disc 25 is gradually reduced, and the suction holding force of the can b is lost at the delivery position 35 due to its own weight. As a structure for slipping off and for attenuating the magnetic action 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 location.

Further, in the case shown in FIGS. 1 and 2, a guide body 37 of a can b formed in a substantially V-shape is attached to the machine body 4 on the upper surface of the inclined disk 25, and the magnet is used.
When the mounting form of 26 is such that the upper surface of the magnet 26 is provided at the same uniform interval with respect to the back surface of the disk 25, it detours upward from the receiving position 28 of the can b and reaches the delivery position 35 on the other side. It receives a uniform magnetic force.

Therefore, by preventing the movement of the can b by the guide plate 37 against the rotation of the inclined disk 25 at the delivery position 35, the can b abutting the guide plate 37 is scraped off by this. , Are collectively collected in a steel can reservoir 38 installed under the delivery position 35.

The guide body 37 also serves to accurately guide the aluminum can b falling from the compression means 2 to the aluminum can reservoir 36.

In FIG. 1 and FIG. 2, 39 is a guide plate for the crushing can b provided between the compression means 2 and the sorting means 3 to the receiving position 28 of the inclined disk 25 in the sorting means 3,
The crushed can b is designed to drop smoothly.
