Thenew E-Shuttle from EISENMANN focuses on the vehicle bodies

The flexibility of the

production process for carmakers is clearly enhanced and

optimized by the new

E-Shuttle introduced by the internationally operating plant manufacturing

company EISENMANN.

Designed for body pretreatment and dip- coating processes, the E-Shuttle can be

individually adapted to the product with regard to dipping curves,

mode of operation or holding time in the process basin.

On the basis of tried- and-tested system

components, the plant manufacturing

specialists in Böblingen have developed anew system –the E-Shuttle – allowing operators to profit from

simple handling, compact design

and consequently from cost-cutting, energy-efficient plant technology.

The shuttle principle

E-Shuttle transports the bodies through the process basins in pretreatment and electrocoating (EC) zones on individual trolleys. Each E-Shuttle trolley has its own entrained controller to define the dipping curve of the transported body and monitor its holding time in the process basin. Both the dipping curves and the process times can be individually programmed by the plant operator for each body type and each process basin. This ensures optimum treatment for each body.Inaddition, certain basins can also be skipped in the pretreatment and EC process.

Continuous position sensing ensures that traverse movements by the overall system are carefully coordinated. All shuttles are coordinated with one another and collisions prevented by ahigher-ranking master control. All these features make E-Shuttle aflexible system which can be individually adapted to the body type and additionally permits model changes or conversions in the production process while maintaining the high quality of the coating.

Rotation cuts operating costs

The E-Shuttle has three freely programmable axes: atraversing axis, alifting axis and a turning axis. These axes permit individually adjustable dipping curves and every conceivable mode of operation, such as roof up, roof down or any position in between. Bodies are dipped in the basins by the combination of lifting and turning movement, with the result that they can be turned through 360° and even positioned completely vertical. The bodies can consequently be quickly flooded in the process basins and drained completely above them. This has apositive effect on bath entrainment and chemical consumption.

Intelligent combination of proven system components

When developing the E-Shuttle, the plant manufacturing company in Böblingen was able to draw on years of experience with dipping electric monorail systems (EMS), heavy-duty EMS and the EISENMANN VarioShuttle. The E-Shuttle is consequently based on components which have proved their value in these systems. The heavy-duty EMS serves as travel unit, used many times in automotive final assembly lines or dip-coating systems. The system also includes the control mentioned above, which has already been installed in more than 5,000 EMS trolleys. The lifting gear with which the bodies are dipped in the basins is also mounted on the EMS trolley –another system component which has already been extensively used in practice.

The VarioShuttle system provides the decisive empirical values benefiting the E-Shuttle. First marketed by the company in 2002, it superseded the rigid pendulum conveyor and also operates according to the shuttle principle outlined above. High flexibility and coating quality are consequently also characteristic of the VarioShuttle system.

System advantages

Predestined for plant updates or for transporting large bodies with apayload of more than 1,000 kg,the VarioShuttle is still included in EISENMANN's product portfolio. Due to its compact design, the new E-Shuttle is destined above all for new facilities in the motor car sector,asproved by contracts already placed by Volkswagen and Porsche. VW will use the E- Shuttle in its new US plant in Chattanooga, as well as in the Bratislava facility.Porsche's new paintshop at the company's headquarters in Zuffenhausen will also be equipped with the E- Shuttle. Space can be saved with this system, as the return line at the side for empty individual trolleys can also be used as abuffer in the event of malfunctions. The slender design of the over- all system is another space-saving factor.
