BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can recovery device for breaking aluminum or iron empty juice cans into small chips, sorting them into aluminum chips and iron chips, and recovering the chips.

0002

BACKGROUND OF THE INVENTION In recent years, resource recovery has become a major social issue from the perspective of environmental conservation, and recovery of empty juice cans is one such issue. Incidentally, empty juice cans and the like are collected by local governments as non-burnable garbage. Additionally, empty cans are also collected by installing an empty can slot in a vending machine selling juice and the like. On the other hand, resource reuse is also important in terms of securing inexpensive resources, and pressed empty aluminum cans are even imported from foreign countries.

[Problem to be solved by the invention]

[0003] The amount of empty cans collected by local governments and the like is small compared to the total amount. Moreover, there are so many types of items that are collected as non-combustible garbage that it is impossible to count them, and it is extremely difficult to separate and collect aluminum cans and iron cans. Less than 30% of it is recycled, and the rest is thrown away in landfills. Therefore, it is thought that the number of empty cans collected is less than 20% of the total.

[0004] Furthermore, the empty cans collected in the attached space of the vending machine are not subjected to any processing such as pressing, and the number of empty cans that can be collected there is limited. Furthermore, even though products in aluminum cans and products in iron cans are sold in the same vending machine, they are not separated at the time of collection.

[0005] An object of the present invention is to provide an empty can recovery device that can separate aluminum cans and iron cans and recover them in large quantities efficiently and in a highly usable state. .

[0006]

[Means for Solving the Problems] In order to achieve the above object, the empty can recovery device of the present invention includes an empty can breaking device having an empty can input port in the upper part and a breaking knife in the center, and It consists of a magnetic belt conveyor that attracts and separates the iron chips from the chips being removed, and each scraper that guides each separated chip into its own container.

[0007]

[Function] In the empty can recovery device configured as described above, the empty cans inputted from the empty can input port are broken into small chips by a breaking knife and dropped. Then, from among the chips, only the iron chips are attracted and separated by a magnetic belt conveyor, and each chip is discharged into a dedicated container by each scraper.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, a first embodiment of the empty can collection apparatus of the present invention will be described.

This empty can recovery device includes an empty can breaking device 1.
and a chip separation device 2.

The empty can breaking device 1 has a cylindrical shape with a breaking blade 3 in the central bulge and a metal sensor 4 at the upper end, and an empty can inlet 5 immediately below the metal sensor 4. was formed.

An example of the breaking knife 3 is shown in FIG. 1. In this system, two rotary blades each having several blades protruding radially from a horizontal axis are arranged in parallel, and the left rotary blade rotates clockwise and the right rotary blade rotates counterclockwise at high speed. In addition to this, the breaking knife 3 includes:
Any tool can be used as long as it can break a thin metal plate, such as a horizontally placed rotating disk with many blades protruding from the surface. Further, the breaking knife 3 is preferably installed at a distance so that even if a child puts his or her hand through the empty can inlet 5, it cannot be reached.

[0012] The metal detector 4 can be the same in principle as the metal detector used at airports and the like to check whether a person is in possession of a knife or the like. The breaking knife 3, the belt conveyor 6, and the magnetic belt conveyor 7, which will be described later, are as follows:
Driving is started upon receiving the signal from the metal sensor 4. Then, after a predetermined period of time has elapsed since the metal tip movement signal from a sensor (not shown) provided below the cutting blade 3 is stopped, the current is cut off and the cutting blade 3 is stopped. Instead of automatic operation in this manner, operation may be performed using a manual switch exclusively for driving and stopping.

The chip separating device 2 includes a belt conveyor 6 and an attached aluminum chip collecting section, and a magnetic belt conveyor 7 and an attached iron chip collecting section.

One end of the belt conveyor 6 is disposed directly below the lower end opening of the empty can breaking device 1, and conveys the metal chips to the left as indicated by the arrow. Its structure consists of belt pulleys at both ends and an endless belt made of rubber or plastic with a reinforcing layer of canvas or steel wire wrapped around it. At the other end of the belt conveyor 6,
A scrapper 8 is installed to receive the transported aluminum chips, and it extends to the container 10.

The magnetic belt conveyor 7 is arranged above the belt conveyor 6 at a predetermined interval and conveys metal chips in the opposite direction to the belt conveyor 6. Its structure is similar to that of the belt conveyor 6, except that magnetic powder is kneaded into the rubber or plastic layer. A scrapper 9 is installed at the end of the magnetic belt conveyor 7 to receive the transported iron chips, and extends to a container 11.

Next, referring to FIG. 2, the process of separating and recovering aluminum cans and iron cans in this empty can recovery apparatus will be explained.

When an aluminum or iron empty can is thrown into the empty can inlet 5 of the empty can breaking device 1, the metal sensor 4 detects it and the breaking blade 3, belt conveyor 6, and magnetic belt conveyor 7 are driven. The empty can is then broken into chips about the size of a 1 yen coin by the breaking knife 3. Then, the chips fall onto the belt conveyor 6 and are carried to the left side. During this time, the chips of the empty iron can are attracted to the lower side of the magnetic belt conveyor 7 and move to the left, and after passing the belt wheel at the left end, they move to the right and are passed onto the scraper 9. Then, it slides down the scrapper 9 and is stored in the container 11. On the other hand, chips from empty aluminum cans are not attracted to the magnetic belt conveyor 7, but continue along the belt conveyor 6, are passed onto the scrapper 8, and are then slid down the scraper 8 and stored in the container 10. Ru. Then, when a predetermined time elapses after the metal chip movement signal from the sensor below the breaking knife 3 is interrupted, the breaking knife 3, the belt conveyor 6, and the magnetic belt conveyor 7 stop.

In the first embodiment, a belt conveyor 6 and a magnetic belt conveyor 7 which are in the same conveying direction are arranged side by side in contact with each other, and the lower end opening of the empty can breaking device 1 is located above the upstream side of the belt conveyor 6 in the conveying direction. A change in the position of the . In this modified example, if the width of the belt conveyor 6 is not increased, the chips of empty iron cans that fall onto it will be sufficiently attracted to the magnetic belt conveyor 7, so the downstream side of each conveyor 6, 7 in the conveying direction is If a scraper is provided for each, chips of empty aluminum cans,
Chips from empty iron cans can be separated and collected.

Next, a second embodiment will be explained with reference to FIG.

This empty can recovery device also includes an empty can breaking device 1.
and a chip separating device 2, and the empty can breaking device 1 is exactly the same as the first embodiment, but the chip separating device 2
There is only one magnetic belt conveyor 7 similar to the first embodiment.

A scrapper 12 is provided downstream of the magnetic belt conveyor 7 in the conveying direction to receive falling aluminum chips and guide them into a container. A scraper 13 is provided to scrape off iron chips that are moving and guide them into a container. The process of separating and collecting aluminum cans and iron cans in this empty can collection device is also not much different from the first embodiment in principle. However, this empty can collection device is superior to the previous example in that it requires only one belt conveyor and is simple.

The empty can collecting apparatus of each of the embodiments described above is not very large, and can be accommodated in a vending machine for juice, etc., as shown by the dotted line in FIG. Furthermore, as shown by the dashed line in FIG. 4, it can be installed as an independent device beside the vending machine, or it can be installed completely independently of the vending machine. In particular, when installed in conjunction with a vending machine, a counter is installed to count the number of empty can input signals issued by the metal detector 4, and when the count exceeds a predetermined number, one can of juice, etc. is served. This will further improve collection efficiency.

[0023]

[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects.

That is, since empty cans are collected in the form of chips, a much larger amount of empty cans can be stored and collected than if they were collected as is. In particular, it is efficient and convenient to collect empty cans that are disposed of in large quantities at event halls, recreational areas, parks, etc. where large numbers of people gather, as the collected items are compact and do not take up much space.

[0025] Furthermore, compared to pressing an empty can as it is and then washing it with water, it is not only much easier to wash with water, but also easier to melt when reusing. Furthermore, aluminum cans and iron cans can be efficiently separated and recovered.

Furthermore, if it is attached to a vending machine for juice, etc., consumers can easily use it, and the efficiency of collecting empty cans is further improved.
