Eisenmann will showcase its E-Shuttle automated conveyor system, designed for pretreatment and e-coat systems in the automotive industry. It can be individually adapted to the specific process with regard to dipping curves, mode of operation or holding time in the process tanks, resulting in highly flexible production processes and high-quality finishing, the company says.
The E-Shuttle transports car bodies through the process tanks. Each shuttle has its own controller that allows a specific dip curve to be defined for each body and a different process time to be programmed for each process tank. Continuous position sensing coordinates all movements system-wide.
Three programmable axes (horizontal, lifting and turning) permit individually adjustable dipping curves and a variety of modes of operation, such as roof up, roof down or virtually any position in between. Bodies are immersed in the process tanks by the combination of lifting and rotation movement, enabling them to be turned through 360 degrees, including to a complete vertical position. This rotation enables quick filling and full drainage of the car bodies, reducing carry-over of process fluid, lowering chemical consumption, and creating fewer rejects and less need for reworking.
The programming of dip curves and process times also ensures that each car body is cleaned and coated evenly, and the rotation of the bodies causes the process fluid to move, minimizing the amount of air bubbles and flooding all cavities to the greatest extent possible.
