DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for breaking a package or compressing and packing various wastes discharged from daily life and business activities around the body from a home or office. The present invention relates to a bag-breaking machine that releases a baler and removes contents, and more particularly to a bag-breaking machine that releases a baler or breaks and discharges waste in a bag.

[0002]

2. Description of the Related Art In recent years, the environment surrounding waste has changed,
Following the "Recycling Resource Promotion Act"
In June 1995, the Law Concerning the Separation and Collection of Containers and Packaging and Promotion of Recycling (Container and Packaging Recycling Law) was enacted and promulgated. It is becoming difficult to landfill easily. Separation of small and medium-sized materials to be treated, especially mixed wastes, resulting from crushing or the like due to such a change in living environment has become an important issue. Fortunately, lightweight materials such as paper, cloth, plastic, and wood are mostly flammable organic materials,
Since heavy materials such as stones contain many non-combustible inorganic substances, sorting by weight is often performed. Therefore, bagged waste discharged from the daily life and business activities of homes and business establishments is also being separated and reused as resources, and the contents are first taken out of the bags for later use in various sorters. There is interest in the development of bag breaking machines.

[0003] As shown in FIG.

And the casing 50A having the fixed side plate 53,
At its lower part, a bag-breaking rotor 50B, which is attached to the circumference of the cylindrical shaft 55 by displacing a long blade-shaped bag-breaking blade 54 in the circumferential direction by 90 ° in the axial direction, is mounted so as to rotate in the direction of arrow R, The inclined side plate 52 is configured to be elastically biased by a spring cylinder 56 to a position close to the long blade-shaped breaking blade 54. Therefore,
The long blade-shaped breaking blade 54 of the rotor 50B receives the dust bag between the resiliently biased small inclined side plate 52 and cuts it by rotation.

[0004]

The conventional bag breaking machine 50 as described above has a simple structure, has few failures, and has been well received. However, the waste discharged from homes and business establishments is garbage. Since various things are mixed from scraps and paper scraps to metal products such as pots and frying pans, small electric products such as toasters and small TVs, devices such as wall clocks and scales, and small jutans, the blades 54 A garbage bag containing hard metal parts or objects with no blades, or a flexible garbage bag consisting mostly of paper, cloth, or plastic sheets, is pushed between the elastically biased small inclined side plates 52. In some cases, it was pushed down without sufficiently breaking the bag.

[0005] The present invention has been devised in view of the above, and does not focus on biting waste in a bag.
Even if hard metal parts or objects with no blades are mixed in with the primary purpose of scraping the bag swelled with balers and garbage and removing the contents, on the contrary, the majority is only paper, cloth, plastic sheets Provide reliable bag-breaking machines that can easily cut and tear even small garbage bags, minimize blade damage, greatly increase the durability of the bag-breaking machine, enable continuous operation, and maintain easy operation.
