Actuators drive ground printing machines
Schaeffler report that its linear actuators are being used on ground printing machines to provide high repeat accuracy and to ensure high inherent rigidity of the support rail. German company Jochum Technology designs and manufactures a range of special purpose ground printing machines used in large format printing applications.
The machines are used to print advertising logos on soft and hard surfaces, including grass (sports stadium pitches), roads, carpet, film, truck tarpaulin sheets and frame coverings. The machines function in a similar way to inkjet printers, printing in multi-colour in a variety of media such as sprays or powders. The linear guidance system for the machine may also need to withstand other media such as water and fertiliser. The ground printing machines use Schaeffler's MLF125-ZR linear actuator with enclosed track roller guidance system and toothed belt drive.
This compact linear drive unit provides high repeat accuracy, low maintenance and high inherent rigidity of the support rail. Acceleration is up to 20m/s2. Speed is up to 4m/s and the stroke length of the linear guidance system is 1,700mm.
