Rieter A 12 UNIfloc That Prioritizes Safety, Flexibility And Energy Efficiency For Aircraft Cockpits

Rieter made a dazzling splash at the Techtextil India 2017 show with display of technology that has been revised over the years. It was originally introduced in 1978 before it became a hit with the technical textile industry especially aircraft cockpits.

The A 12 UNIfloc, an extremely robust and stable new development with a previously unmatched machine concept has hit the floors. The machine has been newly designed from scratch and offers the customer high productivity, flexibility and easy handling.

The story began way back in 1978 when Rieter revolutionized the principle of automatic bale opening and thus the blow room process with the A1 UNIfloc. Then for the first time bales were processed from above with a take-off unit mounted on a mobile tower. Since the Rieter has successively developed this machine in line with market requirements. The new A 12 UNIfloc sets new standards in terms of performance, stable construction, modern safety technology and energy efficiency.

The construction basis for the A 12 is the monocoque design. This was developed for the aircraft industry to allow a light, robust and torsion free construction. This method was used to build the cockpit of the Formula 1 vehicles, to reliably protect the pilots.

It has the feature of a self-supporting construction of the tower and the take-off unit. In comparison to the previous generation, the number of individual parts has been massively reduced. The focus was on a robust, maintenance-friendly machine designed for highest production.

The new A 12 design has realized a new control technique. Alongside the new servo-drive concept, it also includes an innovative and efficient bale profiling. The take-off unit determines the bale height and bale condition by means of scanning force measurement. This allows rapid equalization of bale laydown.

The UNIfloc with innovative bale scanning rapidly achieves high production after changing to a new bale group. With 2000 Kg/h line production, it reliably supplies the cards.

Furthermore, the multi-assortment operation provides flexibility by processing up to three different assortments simultaneously. In cotton processing, the VARIOset function on all Rieter cleaning machines allows a maximal raw material yield to be achieved, as every assortment is allotted an optimal machine setting. Therefore, the subsequent B 12 UNIclean pre-cleaner is automatically adjusted via VARIOset to the properties of the material type being fed.  

To fulfill the strictest energy standards, drives belonging to the highest efficiency class are used. The future oriented drive concept of the A 12 has been systematically developed on torque controlled servomotors. A servo unit with the latest technology enables energy to be recovered. So, for example, the brake power which is generated during reversal of the take-off roller is fed back into the electricity grid. This is a further refinement that makes the A 12 UNIfloc extremely energy efficient.

With the design of the new model, personal safety has been given high priority. Especially with the 2D scanner, significant progress has been achieved in terms of safety standards. The 2D scanner is immune to external influences such as temperature and air currents and immediately recognizes when a person enters the danger area.

The interplay between the scanning force measurement and the patented wobble disk take-off roller with 312 double teeth ensures a continuous extraction to small, uniform fiber tufts and the microtufts. Opening bales to microtufts is the basis for effective cleaning and dedusting by the subsequent blowroom process.

The new A 12 is the absolute highlight and innovation in the technology of automatic bale opening and offers Rieter quality right from the start of the production process.
