1. General information Your Benefit: -No readjusting of reversal points after spool change-No readjusting during winding -Easy to install -Low price The Uhing non-contact FA flange detectingsystem provides a cost-effective means to automate required corrections of rolling ring dri- ve reversing points tried and tested in conti- nuous industrial application.The traversing system incessantly distributingthe material between the spool flanges is only rarely regarded as a cost factor. This only occurs when a conversion to new material dia- meters or coil widths is necessary. The setting then...

Abb. / Fig. 1 Power requirements: Power supply:85 - 264 V A.C., 47 - 63 Hz Compressed Air:4 bar Funktion: Ein Sensor (Lichtschranke) erfat die Spulen- flansche und leitet die Bewegungsumkehr der Verlegung ein. Nimmt die Drehzahl der Verlege- welle mit zunehmendem F߼llgrad der Spule ab, verkrzt sich der Hub, da die Umschaltzeit kon- stant bleibt. Um diese Hubverkrzung auszu- gleichen, kann eine SPS mitgeliefert werden. Function: A sensor (light barrier) detects the coil flanges and trips the reversal of the traversing unit. When the speed of the traversing shaft decrea- ses proportional to...

3. Variants3.1 Usually the FA is operated at constant tra-versing speed 3.2 The traversing system is driven by the tra-versing shaft via a belt drive at during winding. This traversingsystem variant features a drive motor of its own and a bistable relay controller allowing the time between flange detection and reversing impulse to be adjusted. For notes on the relay controller refer to item 7.1. 2. Description 3.3 To prevent profiled material from droppinginto the gap between the last winding and the flange a brief stop of the traversing system before reversal is often useful. For this...

4.3 Mechanic (Fig. 3):Install the traversing system such that the swi-velarm shaft (1) of the light barrier (2) points towards the coil axis (3). Variant 3.2 also requires a connection between winding and traversing shaft by means of a toothed belt or similar. > 4.3 Mechanisch (Abb.3):Die Verlegung muss so eingebaut werden, dassdie Achse des Schwenkarms (1) der Licht- schranke (2) auf die Spulenachse (3) weist. Bei Variante 3.2 ist auerdem die Verbindung von Wickel- und Verlegewelle mittels Zahnriemen o.ߤ. erforderlich. > Abb. / Fig. 3 Abb. / Fig. 4 size="-1">

5. Function Control Establish all connections. Reversal system (6)and swivel arm (1) must switch over when the light beam (17) is interrupted.When the shaft rotates in the normal directionthe traversing system (5) must move into the direction of the swivel arm. In the adverse case you must swap the connec-tions of the swivel arm pneumatic cylinder after having unscrewed the clamping screws (16) and removed the slide (11). 6. Adjustments6.1 Basic setting Adjust the slide (11) so it matches the flange dia- meter (18) of the used spool. To do so loosen the clamping screw (16). Largest...

6.2 Fine adjustment Precise adjustment ofthe traversing stroke occurs by changing the angle (a) of the swivel arm (1) during winding. To do so turn the adju- sting screws (8) for each stroke direction accor- ding to the markings. Turning in +ԓ direction results in a stroke increase and morematerial being wound atthe flange. Use the sca- les (15) to verify the changes.To quickly find the optimum setting you mustcarefully observe the first layers in particular. Make small corrections at a time only as too great a change will cause oscillations around the ideal point and prolong the adjustment...
