ES2241451A1 - Scrapped vehicles bodywork recycling plant, includes shot peening and robotized painting systems with automatic residues separation - Google Patents

Abstract

The scrapped vehicles bodywork recycling plant has a mechanical cleaning zone with an automatic paint fragments separator. A robotized painting and drying zone using phosphating antioxidant paint is also provided.

Description

Body recycling plant.

The process is developed through the following production units within the characteristics of the same that can be considered as a production line semi-automatic

1.- Arrival of pieces

They are stored in the specifically intended area For these pieces.

2.- Reception area and Selection of pieces

Only those pieces that have Affected parts that need repair. They will count on everything case with damages that are less than or equal to 5% of the total Of the piece. Higher than this established percentage of five percent in principle are excluded.

Therefore, a prior check by the person in charge of collecting and transporting the merchandise object of recycled, or where appropriate by the company supplying the material cousin.

Later the pieces go to the section of disassembly, leaving only the material to be recycled and are destined to the cleaning and decontamination zone.

3.- Shot Blasting Zone

Zone that allows the entry of up to ten pieces to undergo a pickling process.

The pieces are subjected to the pressure they exert certain injectors placed in different positions that they expel sand grit, under pressure leaving the pieces completely pickled.

Technical characteristics

It is a closed cab with closure perimeter based on sandwich panels assembled by female male systems.

Its dimensions are 3 x 3.30 meters

It will also have a roof based on panels modular and pedestrian access doors with locking devices to Adjustable pressure, according to current safety standards.

For input and output of materials you will have two galib of 1700 x 500 mm.

It will contain a shot blasting equipment with engine power 7 hp, and pipes for connection to the sanding grid that will be outside the cabin and where the remains will be collected after the shot blasting process.

4.- Blow zone

The doors may come with some particles or shot blasting impurities, so in this area the parts to a pressurized air cleaning process.

The extracted particles are recycled, being incorporated back into the blasting zone.

5.- Repair Zone

In this area, the pieces that so will be submitted require the necessary repairs (small repairs, since only damages for a maximum of 5% of the total of the piece).

Four workbenches will be located to repair and sand the parts that require it.

6.- Painted area

The pieces are hung on a production line and come into contact with a robot destined to paint each of the pieces.

The painting process is articulated through injection paint pumps with front and bottom sensors painting 95% of the piece. The painting process can also be made up to 100% of each piece, therefore having a complete finish

The employer chooses to consider as more convenient only to carry out 95% of the total, making 5% remaining manually. The option is chosen before the possibility of introducing in the whole process the recycling of "gates butts "which, having neither the same size nor design, do not They can paint the same way. The terminations would be made in the two cases manually, without this implying in any case that the product loses quality, in fact it has more control of quality when there is a person in charge of this phase who will review each piece and will touch up whatever is necessary.

You can choose to have the installation perform a 100% painted of the pieces (needing anyway a person to perform quality control) but this can be done incorporate in a second phase of project expansion, because in these moments are about diversifying considering less costs in machinery and ensuring that the quality control is perform without reducing the quality of the product.

In the same way, the application of ISO 9000: 2000 Quality Standards for this process recycling.
