Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for compressing empty cans such as juice, cola and beer.

[0002]

2. Description of the Related Art Recently, empty cans of juice, cola, beer and the like have been collected for the purpose of reusing resources and preventing environmental pollution due to mass disposal. Then, a method of compressing empty cans is adopted as one of means for efficiently collecting the empty cans, and then storing, transporting, and reusing them. This is disclosed, for example, in JP-A-56-14097, JP-A-56-160595, and JP-A-57-1.
As described in Japanese Patent Publication No. 03798, etc., a pressing plate and a pressure receiving plate, which are arranged to face each other in a case, are pressed against each other by human power such as stepping or using a motor or the like as a drive source through a link mechanism or the like to sandwich an empty can. It is to be compressed into a plate with.

However, in many cases, the contents remain in the empty can which is compressed. Therefore, the residue adheres to the pressing plate, the pressure receiving plate, and the driving mechanism arranged in the case during the compression process. These adhered residues such as juice, cola, and coffee contain extremely large amounts of sugar, and these solids that evaporate and solidify are accumulated on the pressure plate, pressure plate, and the rotating parts of the drive mechanism. It Therefore, the operation of the processing machine becomes defective and it becomes unusable. Since this solidified sugar is organically bound such as crystallized, it is difficult to remove it by, for example, spray cleaning or brush cleaning that is usually performed, and it takes a lot of labor and time to repair and recycle the processing machine. There is also a problem that the residue such as juice, cola, beer, etc. that adheres to it will decompose or ferment over time to give off a bad odor and become a source of flies and the like, causing environmental pollution. In particular, these problems are likely to occur during the summer when the demand is high and a large number of empty cans are generated, because the temperature is high.

[0004]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that in the conventional processing method, the residue renders the processing machine unusable, and further, foul odors and flies occur.

[0005]

The present invention provides a method for compressing an empty can in which an empty can is sandwiched between a pressing plate and a pressure receiving plate which are arranged so as to face each other and compressed. A structure in which the cleaning liquid is jetted between the pressing plate and the pressure receiving plate, and the cleaning liquid is jetted from above between the pressing plate and the pressure receiving plate before the empty can is compressed, and then the cleaning liquid is again pressed between the pressing plate and the pressure receiving plate. As a means for solving the above-mentioned problem by a structure in which an empty can is compressed while being ejected from above between the plate, the processing machine is not disabled by the residue, and further, a foul odor or a fly is generated. (EN) An object of the present invention is to provide an empty can compression processing method.

[0006]

Function: The residue flowing out of the empty can during the compression is washed away with the cleaning liquid and prevented from adhering to the pressing plate, the pressure receiving plate and the drive mechanism arranged in the case. Also, before compression, press plate,
By pre-wetting the surfaces of the pressure receiving plate and the drive mechanism arranged in the case, the adhesion of the residue can be prevented more effectively.

EXAMPLE An example of the present invention will now be described. The figure shows an example of a foot-operated empty can compression processing machine for carrying out the present invention, which is similar to a conventional processing machine. A pressing plate 2 and a pressure receiving plate 3 are vertically arranged along a back plate 4 in a vertical case 1 in the shape of a case 1. The lower end of the pressing plate 2 is formed by a shaft 6 which is installed on the side plates 5 and 5. It is rotatably supported and disposed on the pressure receiving plate 3 so as to be freely opened and closed.

The driving mechanism for opening and closing the pressing plate 2 is a foot lever 9 having a pedal 8 protruding from the lower part of the front plate 7 of the case 1 and a boosting mechanism connected between the pressing plate 2 and the foot lever 9. And the link mechanism 10 constituting the.

Further, the pressure plate 2 and the pressure receiving plate 3 of the side plates 5 and 5 are arranged.
The liquid tank 12 is arranged along the lower surface of the top plate 11 at the upper part of the
Spray nozzles 14 and 14 are provided for spraying the cleaning liquid filled in the spray pump 13 with the spray pump 13. Jet pump 1
Reference numeral 3 is a reciprocating pump that is usually used for pumping liquid, and a piston is connected to the upper part of the side end surface of the pressing plate 2 and reciprocates in conjunction with the opening / closing operation of the pressing plate 2.

Reference numeral 15 in the drawing is a charging port for the empty can 16,
Reference numeral 17 is a discharge port of the compressed can 16 and reference numeral 18
Reference numeral 19 is a window for confirming the amount of liquid in the liquid tank 12 and the storage tank 18 from the outside of the case 1, and reference numeral 21 is a foot lever 9. It is an attached return spring.

In order to carry out the present invention using the empty can compression processor having the above-mentioned structure, first, the liquid tank 12 is filled with a cleaning liquid containing an odor preventive agent, an insect repellent agent and a surfactant, and a predetermined portion is filled. Install it. And empty can 1 to be processed
6 is charged from the charging port 15. The inserted empty can 16 falls between the pressing plate 2 and the pressure receiving plate 3. Then pedal 8
When the foot lever 9 is rotated by stepping on, the link mechanism 1
0 rotates the pressing plate 2 around the shaft 6 in the direction of the front plate 7, and the pressing plate 2 closes and comes into pressure contact with the pressure receiving plate, so that the empty can 16 is sandwiched and compressed into a plate shape.

At this time, although the residue in the empty can 16 flows out with the compression, the jet pump 13 is activated by the closing operation of the pressure receiving plate 3 to spray a certain amount of the cleaning liquid filled in the liquid tank 12. It spouts in a mist state from above between the pressure plate 3 and the pressure receiving plate 2 through the ports 14, 14. Therefore, the empty can 16, the pressing plate 3, and the pressure receiving plate 2 in which the cleaning liquid ejected in the form of mist is compressed
The residue flowing out from the empty can 16 that has been compressed on the surface of the case is washed away and is not accumulated on the pressing plate 3, the pressure receiving plate 2, and the turning portion of the driving mechanism such as the stepping lever 9 and the link mechanism 10 in the case. It collects in the storage tank 18 arranged in the lower part of the inside of 1. In particular, in this embodiment, since the cleaning liquid is sprayed in the form of a mist, it is possible to clean a wide area using a very small amount of the cleaning liquid, and maintenance such as replenishment and recovery of the cleaning liquid is extremely easy, but it is not always in the mist form. You don't need to squirt. Further, since the cleaning liquid contains the surfactant, the cleaning is sure and quick.

When the compression of the empty can 16 is completed, the stepping force on the pedal 8 is released, and the stepping lever 9 moves the spring 21.
As a result, the link mechanism 10 and the pressing plate 3 are also returned to their original open positions. Therefore, the compressed empty can 16 is discharged from the discharge port 17. The surface of the compressed empty can 16 is also washed with the washing liquid. When it is confirmed from the window that the cleaning agent containing a predetermined amount of residue has accumulated in the storage tank 18, the storage tank 18 is taken out from the case 1 and discarded. In the present embodiment, since the cleaning agent contains the deodorant and the insect repellent, even if the cleaning agent containing the residue is stored in the storage tank 18 for a long period of time, such as in hot and humid summer, a bad odor is generated or flies It is extremely easy to maintain because there is no concern about environmental pollution and no pests such as these occur.

As described above, the present invention can be carried out by adding a very simple apparatus to the conventional processing machine as in the present embodiment, and the residue in the empty can 16 is washed with a very small amount of cleaning liquid. Although the treatment can be performed efficiently, the pedal 8 is not first put into the pedal 8 and the cleaning liquid is sprayed to wet the surfaces of the pressing plate 3, the pressure receiving plate 2 and the drive mechanism arranged in the case 1. In that case, a greater cleaning effect can be exhibited as compared with the case where the cleaning liquid is sprayed only during compression as in the above-mentioned embodiment. This is because the interfacial activity between the residue and the surfaces of the pressing plate 3, the pressure receiving plate 2 and the drive mechanism arranged in the case 1 is significantly reduced.

Although the present embodiment shows a foot-operated empty can compression processor, it goes without saying that a mechanical empty can compression processor using an electric motor can be used in the same manner. Further, although the ejection pump 13 and the ejection port 14 are separate bodies, an ejection device in which these are integrated may be used. Further, in the present embodiment, the piston of the ejection pump 13 is connected to the pressing plate 2 to eject the ejection pump 13. Since it is configured to interlock with the opening / closing operation of the pressing plate 2, a special drive mechanism for operating the ejection pump 13 is not required, but the cleaning liquid may be ejected along with the closing operation of the pressing plate 2. It doesn't matter.

[0016]

According to the present invention, the cleaning liquid is jetted from above between the pressing plate and the pressure receiving plate when the empty can is compressed.
Since the residue in the empty can flowing out by the compression is washed away at the same time as the compression, the residue is not accumulated and solidified on the pressing plate, the pressure receiving plate and the rotating portion of the drive mechanism. Therefore,
The processing machine does not become unusable, no bad odor or flies are generated, and the surface of the compressed can is cleaned at the same time, so that the subsequent processing can be performed hygienically. Further, a high cleaning effect can be expected because the cleaning liquid is jetted from above onto the facing surfaces of the pressing plate and the pressure receiving plate before the empty can is compressed. Furthermore, when the cleaning liquid is sprayed in a mist state, it is possible to clean a wide area using a very small amount of cleaning liquid, and maintenance such as replenishment and recovery of the cleaning liquid is extremely easy. Furthermore, when the cleaning liquid contains a surfactant, the cleaning can be carried out more reliably and quickly, and when the cleaning liquid contains a deodorant or an insect repellent, even if the residue is stored, a bad odor is generated or fly or the like is generated. No pests are generated, there is no concern about environmental pollution, and maintenance is extremely easy.
