Brushless pivoting frame operated via web browser

At this year's Interpack, Erhardt+Leimer will present a new pivoting frame with brushless drive technology for narrow-web applications which can be operated via a standard web browser: the DRB23 from the ELGUIDER product family.

Commissioning of the new unit couldn’t be easier. All the key parameters are already pre-set on delivery; if any adjustment should be required, a commissioning wizard guides the operator step-by-step through the additional input windows that need to be filled in. The unit is operated via a touch display (RT 4008). The installation situation is visualized for the customer on this display in exactly the same way as it presents itself to the operator on the actual machine. Optionally the device can be commissioned and operated from any location via its web interface. In the same way, it is possible to change parameters, display the network structure and access the connected sensors.

Thanks to the brushless drive the pivoting frame is maintenance-free. It is also quite a bit more compact than comparable competitor models. Reference runs are no longer required thanks to the integrated absolute value encoder, which also ensures that the current position is saved in the event of a power failure. The use of high-quality roller bearings instead of simple slide bearings effectively prevents stick-slip. In addition, all cable glands are secured with strain relief to prevent damage to the cables. The new unit also impresses in terms of control dynamics, with a control frequency of up to 8 Hz.

In addition to infrared sensors and ultrasonic sensors, the color line sensor FE 52 can also be used for web guiding. This sensor has a trigger mode, which means that there is no need for a continuous guiding criterion on the web.

Various roller surfaces are available to adapt the pivoting frame to the webs processed by the respective customer. As an option it is also possible to integrate a splice table with an adhesive roll and pneumatic web clamps.

Besides the new pivoting frame Erhardt+Leimer will showcase some more web guiders, the ELSCAN video system for print monitoring as well as different edge sensors at their stand A36 in hall 12.
