BACKGROUND OF THE INVENTION
The present invention relates to an automobile dismantling method for dismantling a discarded automobile.
[0002]
[Prior art]
Conventionally, when dismantling a discarded automobile, generally, only easily removable parts such as tires and batteries are removed, and then pressed and cut with a shredder to be treated as industrial waste. By the way, in recent years, from the viewpoint of effective use of resources and the like, it is required to collect and recycle metal parts and resin parts without treating the automobile to be discarded as industrial waste.
[0003]
Some parts attached to the car can be removed relatively easily, but for example, the outfitting resin parts such as seats, instrument panels or garnishes are attached to the interior of the car. The removal work was troublesome because of its poor nature.
[0004]
For this reason, an automobile disassembly method has been proposed in which the roof portion of the automobile is cut at the pillar portion to remove the roof portion, and parts can be easily removed in the vehicle interior with good workability (for example, Patent Documents). 1).

[Problems to be solved by the invention]
By the way, although only the separation / recovery of outfitting resin parts in the vehicle interior is described in Patent Document 1, in recent years, in addition to the separation / recovery of outfitting resin parts of automobiles, metal parts such as iron, aluminum, and copper are also separated / recovered. And are required to be recycled.
[0007]
However, in the above-mentioned Patent Document 1, the vehicle body lower structure portion including the front structure portion with the engine or the like after the outfitting resin parts in the vehicle interior are removed is cut by being cut by a shredder after being pressed. Since the resin parts and a large amount of metal parts were mixed together as waste, the metal purity was low and recycling was impossible.
[0008]
Moreover, in the structure which isolate | separates and separates only a roof part like the said patent document 1, when it is going to isolate | separate and collect metal parts, such as an engine (an engine accessory part is included) from the inside of the engine room of a vehicle body, Since the structural parts other than the roof part are provided without being separated as they are, for example, when working from the vehicle interior side, as shown in FIG. 8, the operator 102 sits on the seat 101 in the vehicle interior and places the instrument panel It was necessary to work from 103, and workability was poor.
[0009]
Therefore, the present invention can improve the separation and recovery rate of metal parts from a car to be dismantled with high purity, and further allows the metal parts and resin parts to be separated and recovered from the car to be dismantled with good workability. The purpose is to provide.
[0010]
[Means for Solving the Problems]
