If the search for new materials in the shipbuilding sector is playing an important role in the innovation of machines with a view to lightening them, earthmoving machines remain anchored to a primary objective: robustness which translates into their adaptability to different types of terrain and under different operating conditions.
For this reason, we had to interface with pieces exceeding 12.5 tons , but we also had to study a customized system capable of meeting the company’s needs in terms of high production cadence and optimization of workflows .
The result was an automatic painting system equipped with LESTA robots with self-learning for painting.
The automatic liquid painting system supplied by Eurotherm
The customer’s primary need was to obtain a finish that would guarantee the product high resistance to wear. Earthmoving machines in fact, they operate in extreme conditions and must be designed not only to withstand adverse environmental conditions, but also to meet increasingly demanding quality standards.
The painting system was thus designed based on the needs of the customer who required to transport counterweights of trucks, cranes, earthmoving machines weighing even more than 12.5 tons with a tact time of 30 minutes .
This is an automatic liquid painting line for heavy pieces, the system for transporting the pieces on trolleys linked to a roller conveyor has been studied according to the customer’s needs.
The complete painting cycle includes:
- manual loading on the piece transport trolley;
- automatic painting with a first layer of primer
- drying at 30°C;
- drying at 50°C;
- manual painting for finishing;
- withering;
- manual unloading of finished pieces.
