Side guides / screw downs

 

Task

Side guides are used to centre the metal strips upstream of the roll stands. In some cases, mechanical cam switches and/or absolute encoders are still used for position detection and control. Attachment to the available shaft end of the drive is a widespread solution. To improve control accuracy and as a consequence the quality of the material the customer desires a directly mounted, compact solution without downstream transfer box gearing (gear backlash). The same demands apply to adjusting the rolls for thickness control purposes.

 

Huebner Solution

The advantage of the modular system U-ONE® from Johannes Hübner Giessen is that just the universal basic device is mounted to the side-guide gearbox, while the functional modules are housed externally on the switchboard. A single fibre-optic cable is used to achieve the EMC-compliant connection, a solution that offers considerable savings with regard to cabling time and costs. The system is programmed via a central USB interface. The system is easily extended thanks to the series (side-by-side) plug-in function modules in conjunction with the low-cost of spare parts.
