If necessary, saturated filter boxes can even be replaced during production.Īt the end of the painting process, the body surface is checked at a quality control station. Another benefit of the technology is how easy it is to use. The system uses inexpensive cardboard filter boxes to efficiently separate overspray. With the color change technology and the EcoBell Cleaner D2 for cleaning atomizers, paint loss during color changes and consumption of flushing agent and solvent are also minimized.ĭürr’s EcoDry X dry separation system, which doesn’t require water or chemicals, is another technology used in the new paint shops.

High-rotation atomizers with electrostatic charging use material efficiently. At the same time, the technology is more environmentally friendly. The robots enable Sinotruk to achieve the best possible painting results in terms of color shade, flow values and uniform layer thicknesses. Then, a base coat and clear coat in each paint shop are applied by 19 EcoRP painting robots, which are equipped with EcoBell3 high-rotation atomizers. Next, two EcoRS sealing robots from Dürr seal the inner seams, and another two apply liquid sound deadener in a fully automatic process. This saves resources and reduces operating costs. The immersion tanks for the rotational process are smaller than with a traditional pendulum conveyor, which means that less energy and chemicals are required. Each trolley has a conveying drive and a rotating drive, which enable horizontal and rotating movements to be controlled independently for each cab. Charging points are located where the AGVs are stationary for picking up or setting down truck bodies.Īt the beginning of the painting process, truck bodies pass through Dürr’s RoDip E rotational dip process, which enables engineers to individualize the pretreatment and cathodic electrocoating processes to optimize quality when running different cab models.Įach cab is transported through the pretreatment and electrocoating processes using a freely programmable trolley.

The AGVs are fully charged in just 1.5 minutes.

The fleet is intelligently controlled by DXQ control software, which ensures that all AGVs execute their transport assignments and are always on the move. The EcoProFleet AGVs can carry a maximum load of 1,000 kilograms. With the Sinotruk lines, the AGVs are being used to transport truck cabs for the first time.

The AGVs are specifically designed for use in paint shops and are already in use in passenger car production. The paint shops are being built in Laiwu and Zhangqiu in the eastern Chinese province of Shandong.ĭürr’s EcoProFleet line of AGVs will transport the vehicle bodies through the line, allowing for a flexible layout and enabling Sinotruk to expand the line or integrate new models in the future. Equipped with state-of-the-art technology, the paint shops will be used to coat and paint truck cabs and pickups for Sinotruk’s premium brands, Ji’nan Truck and Ji’nan Commercial Vehicle. The aim is to optimize the entire value chain using digitized processes and data flows with high transparency and predictability, short throughput times, low inventories, and high flexibility.ĪGVs Convey Truck Cabs in Automated Paint Linesĭürr is building two automated paint shops for Sinotruk, a Chinese manufacturer of heavy trucks. The autonomous AGVs are an integral part of Continental’s Industry 4.0 strategy.
