There is no danger of getting dirty with falling fuel or oil. For this reason, the collection work of the collected parts that must be handled in a particularly polite and clean condition can be performed in a clean environment where the floor is not soiled with fuel or oil, and the limbs of the workers who perform the collection work are also stained with fuel or oil. As a result, the quality of the collected parts is good.

In the nibbler treatment process 5, using heavy equipment like nibbles, large parts that are difficult to handle manually, such as engines, mufflers, catalysts, undercarriages (forward and backward), radiators, harnesses, etc. Remove and collect. Because heavy equipment such as nibra is used, it is possible to remove heavy objects safely and efficiently with powerful force.
Further, in the nibbler processing step 5, a large dismantling is performed such that the vehicle body in a state where necessary large parts are removed is largely bent or crushed.

The final processing step 6 is a step of obtaining iron scraps by finely cutting the car body (mostly iron scraps) dismantled in the nibbler processing step 5 using a shredder or the like.
Non-volatile impurity elements (Trump elements) such as copper, tin, nickel, and chromium are carefully removed from the vehicle body that is shredded in each process described above, so that the purity of iron scrap is increased (93- 97%), which is a marked improvement in quality compared with the average purity of iron scrap obtained by the conventional recycling system of about 82 to 85%.

In the present invention, as shown in FIG. 2, the automobile parts / members to be collected (collected parts) are divided into 11 by manufacturer, 12 by displacement, and 13 by model, and each site (each process) is assigned according to the code. Then, the collected results are input to the computer as data management input 7, and the accumulation is constructed as a database. An example of how to use this database construction 8 is to provide information 9 to the work site. The inventory quantity of the recovered parts and the planned sales amount when the inventory is sold are displayed on the display screen for each site. It is possible to make it possible to display.
If such use is made, it becomes useful information as work information for field workers, can be used for improving work efficiency and preventing mistakes, and helps managers to make efficient management plans.
In addition, in collaboration with automobile manufacturers and parts manufacturers, it is possible to prepare for the development of more efficient separation and disassembly methods by pre-analyzing what precious metals and other valuable resources are used in recovered parts. Become.
