DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for processing empty cans of beverages such as juice, coffee and beer, and empty plastic bottles such as mineral water.

[0002]

2. Description of the Related Art In recent years, with the increase in consumption of beverage cans and drinks such as juice, coffee and beer, and beverages in plastic bottles such as mineral water, treatment of empty cans and empty bottles has become a major problem. Sorting process, of course,
Various countermeasures such as processing returned to the producer, processing at local governments, etc. are being studied, but after the contents are consumed, the inside is empty, so it is possible to deform it to reduce its own volume. However, the volume of the garbage can be remarkably reduced only by the implementation. Therefore, as an empty can press machine,
Devices that compress and reduce the volume have appeared.

For example, in Japanese Utility Model Laid-Open No. 55-98497, a concave-shaped empty can mounting table and a convex-shaped empty can presser are attached to a leg 2 and a lever 5, respectively. Some press the empty can by strongly closing both. Further, Japanese Utility Model Application Laid-Open No. 58-157297 discloses an apparatus in which a convex portion having a mountain shape is formed at the center of a pressure head and the can is folded in such a manner that the can is folded in half from the center. Japanese Unexamined Patent Publication No. Sho 60-176899 discloses an apparatus for crushing an empty can by providing a plurality of chevron-shaped projections on both the pressing plate and the pressing seat in a perpendicular manner.

[0004]

The problem common to these conventional devices is that they are all for empty cans, and no measures are taken for empty PET bottles. The processing of empty PET bottles having different shapes is not always successful, and there remains a problem in that a processing device provided with an angle cannot be commonly used. An object of the present invention is to solve such inconveniences and to provide an empty can / pet bottle crusher which can process not only empty cans but also empty plastic bottles or objects having an equivalent shape. I have.

[0005]
