Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can collecting device that breaks into small chips of aluminum or iron juice or the like and separates and collects them.

[0002]

2. Description of the Related Art In recent years, the recovery of resources has become a major social problem from the viewpoint of environmental protection, and the recovery of empty cans such as juice is one of them. By the way, empty cans such as juice are collected as non-burnable garbage by local governments and the like. In addition, vending machines for juice and the like are also provided with empty can inlets for collection. On the other hand, the reuse of resources is also important in terms of securing inexpensive resources, and empty cans of aluminum are imported from pressed ones from foreign countries.

[Problems to be Solved by the Invention]

The number of empty cans collected by local governments is small in the total amount. Moreover, the types of articles collected as incombustible waste are so large that it is impossible to count them, and it is extremely difficult to separate and collect aluminum cans and iron cans from among them, which is a resource. Less than 30% is reused and the rest is abandoned in landfills. Therefore, the number of empty cans collected is less than 20% of the total.

The empty cans collected in the space attached to the vending machine are not processed by pressing or the like, and the number of empty cans that can be collected therein is limited. Moreover, although aluminum cans and iron cans are sold in the same vending machine, they are not sorted at the time of collection.

According to the present invention, an aluminum can and an iron can are separated from other containers and the like in large quantity and efficiently.
Further, it is an object of the present invention to provide an empty can collecting device that can collect the cans in a highly usable state.

[0006]

In order to achieve the above object, the empty can collecting device of the present invention has a guide passage having an input port, a delivery passage, and a non-metallic input material pushed out from the guide passage to the delivery passage. A pusher, a device for pressing a can arranged in the guide path, a cutter arranged below the cutter for cutting the press can into chips, and a chip conveying device arranged below the cutter.
It is composed of a magnet roller which is arranged at an interval at the conveying end thereof, and each container which accommodates each chip dropped by the chip conveying device and the magnet roller.

[0007]

[Operation] In the empty can collecting device configured as described above, if an empty can or the like is thrown in, and if it is a non-metallic one, the pusher operates to push it out from the guide passage to the dispensing passage, If it is also, go down the guideway and fall. The input is then pressed, cut into chips,
It is dropped onto the chip carrier and carried to the magnet roller side. The aluminum chips are dropped as they are into the container below them, and the iron chips are attracted to the magnet roller and dropped into the container below them.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the empty can collecting device of the present invention will be described with reference to FIGS.

This empty can collecting device is mainly composed of a guide path 2 having an opening 1 for empty cans, a chain belt 3 for preliminary pressing, a press roller 4, a cutter 5, a chip conveying belt 6, a magnet roller 7 and a pusher 8. Has been done. Reference numeral M in FIG. 1 is a motor for driving the chain belt 3, the press roller 4, the cutter 5, the chip conveying belt 6 and the magnet roller 7, and here, a motor of 100 V and 400 W is sufficient, and therefore, It can also be used for home use.

The input port 1 has a lid that can be opened by the hand of an inserter when inserting an empty can. The guide path 2 has a tubular shape in which the upper portion is upright and the lower portion is inclined. The upper and lower of the uprights, and the sensor S _1, S ₂ respectively provided, the sensor S ₁ is used to detect that the lid has been opened by the supplier who is closed, when closed The chain belt 3, the press roller 4, the cutter 5, the chip conveying belt 6 and the magnet roller 7 are driven by the signal emitted. Therefore, while the lid is open, they are not driven and it is safe to put your hand in the back. Further, the sensor S ₂ electrically detects whether the input is made of metal or non-metal, and a plurality of sensors S ₂ can be provided in the width direction. In the case of providing multiple glass bottles, when a glass bottle with a metal lid is thrown in, only some of the sensors will judge that it is made of metal. Make sure it is a metal input.

The chain belt 3 is endlessly stretched between the driving roller 3a and the driven roller 3b, and is arranged in the inclined portion of the guide path 2 closer to the bottom wall surface toward the downstream side. When the thrown-in empty can falls to the position of the chain belt 3, the empty can moves further downstream while being crushed by the chain belt 3 moving in the direction shown by the arrow in FIG.

The press roller 4 is located immediately downstream of the chain belt 3 in the inclined portion of the guide path 2 and is for fully pressing an empty can pre-pressed by the chain belt 3.

The cutter 5 is arranged on the downstream side of the press roller 4 in the inclined portion of the guide path 2, and a cutter as shown in FIG. 3 is raised as an example. This is because a plurality of circular rotary blades 51, 52 having different diameters are alternately stacked (the total thickness is about the length of the can), a portion driven by a motor M, and a receiving cutter 53 arranged in the vicinity thereof. It has become. As shown in FIG. 1, each of the circular rotary blades 51 and 52 has a saw-tooth shape, and the larger the number of rotary blades per unit length, the smaller the chip can be obtained.
The receiving cutter 53 includes circular rotary blades 51, 52 having different diameters.
Unevenness is formed along the outer contour of the. In addition to this, the cutter 5 may be any cutter as long as it can break a thin metal plate.

The chip conveyor belt 6 is a rubber or plastic endless belt which is placed below the cutter 5 and is stretched over belt wheels 6a and 6b at both ends and has a reinforcing layer of canvas or steel wire. , The metal chip is transported to the right side as shown by the arrow. A scraper 9 for removing the conveyed aluminum chips is installed on the lower left side of the chip conveyor belt 6, and a container 11 is arranged below the chip conveyor belt 6.

The magnet roller 7 is arranged on the right side of the chip carrying belt 6 with a predetermined space therebetween, and is driven to rotate in the direction opposite to the chip carrying belt 6. On the right side of the magnet roller 7, a scraper 10 for removing the iron chips adsorbed and conveyed is installed, and below the magnet roller 7, a container 12 is placed.

Each of the containers 11 and 12 is made of a mesh so that a liquid such as juice that adheres to the input material or remains therein can be permeated. Then, the liquid that has passed through the net of the container is discharged from the discharge port 13 at the lower part of the device to the external tray.

The pusher 8 is placed on the side of the upright portion of the guide path 2 and is guided by an electromagnetic solenoid when the sensor S _{2 determines} that the input is a non-metallic material (paper, glass bottle, etc.). It is a means for jumping out into the path 2 and pushing the input material into the payout path 14 provided separately from the guide path 2. At the end of the payout path 14, there is a payout opening 15 through which the non-metallic charge is discharged to the outside. Note that the non-metallic input material may be crushed in the apparatus and stored in the internal container without being discharged to the outside.

In the empty can collecting device having such a structure, the lid of the charging port 1 is opened, an empty can or the like is charged, and the charged material passes through the position of the sensor S ₂ and it is determined that it is a non-metallic one. Then, the pusher 8 is activated and the input material is discharged from the discharge path 14 to the discharge port 15. When it is determined that the input is made of metal, the pusher 8 does not work and advances along the guide path 2 and falls. Then, when the sensor S ₁ detects that the lid of the input port 1 is closed, the chain belt 3, the press roller 4, the cutter 5, the chip conveying belt 6 and the magnet roller 7 are driven. The input material is crushed by the chain belt 3 and the press roller 4 and cut into very small chips by the cutter 5 (the volume is 1/15 or less of the volume of the can before pressing). The chips are dropped onto the chip transport belt 6 and carried to the magnet roller 7 side. The aluminum chips move on the chip conveyor belt 6 as they are, come to the ends and drop, and are housed in the container 11. Even the hard-to-remove items are scraped off by the scraper 9 and finally stored in the container 11. The iron chips are adsorbed from the chip conveyor belt 6 to the magnet roller 7, conveyed to the position of the scraper 10 and scraped off there, and then the container 12
Housed in. Then, when the movement signal of the metal tip from a sensor (not shown) below the cutter 5 is cut off and a predetermined time elapses, the chain belt 3, the press roller 4, the cutter 5, the tip conveying belt 6 and the magnet roller 7 are provided.
Stops.

The empty can collecting device described above has a frontage, a depth and a height of 480 mm, 490 mm and 840 mm, respectively, and can be sufficiently stored in a vending machine for juice or the like. Of course, it can be installed as a stand-alone device beside the vending machine, or can be installed independently of the vending machine. In particular, when installing in association with an automatic vending machine, if a counter is provided and one can of juice or the like is serviced by counting a predetermined number of times or more, the collection efficiency is further improved.

[0020]

Since the present invention is constructed as described above, it has the following effects.

That is, the aluminum can and the iron can can be separated from other containers and collected efficiently. Even iron cans with aluminum lids can be reliably separated and collected. It is possible to store and collect a much larger number of empty cans as compared to those that are collected as they are without being made into chips. In particular, it is convenient to collect a large amount of empty cans at an event hall, a recreation area, a park, etc. where a large number of people gather, because the collected objects are compact, space saving, and efficient.

Even if each metal chip is discarded without being reused, the volume of the chip becomes 1/15 or less of the container, so that the period of use at the disposal site can be extended 15 times or more. In addition, when reused, it can be washed with water much more easily and melted more easily than the case where the empty can is pressed as it is and then washed with water.

Furthermore, since the device is small, if it is attached to a vending machine for juice or the like, it can be easily used by consumers and the empty can collection efficiency is further improved. Since it can be used with a household power supply, it can also be used easily at home.
