IPC: B21C1/02
Filed: 1990-03-15
Abstract: Die Erfindung betrifft ein Verfahren zur automatischen Absenkung der Ziehgeschwindigkeit von Trommelziehmaschinen für Rohre oder dergleichen vor dem Ziehende einer Rohrlänge, wobei Jede von mehreren nacheinander gezogenen Rohrlängen nach einem Zug durch das Ziehwerkzeug in einem Aufnahmekorb gesammelt wird, der jeweils nach dem Ziehen der anderen Rohrlängen schrittweise in eine Ablaufstation transportiert wird, von wo aus ein weiterer von mehreren in gleicher Reihenfolge ablaufenden Ziehvorgängen eingeleitet wird. Um ein Verfahren und eine Vorrichtung zur automatischen Absenkung der Ziehgeschwindigkeit von Trommelziehmaschinen zu entwickeln, das bzw. die auf einfache Weise durch den Bedienungsmann beim ersten Zug eines jeden Ziehspiels aktiviert werden kann und dann für die weiteren Züge eben dieses Ziehspiels nicht mehr verändert wird, wird vorgeschlagen, daß die Länge des gezogenen Rohres jeder im Umlauf befindlichen Rohrlänge beim ersten Zug gemessen und registriert wird, daß beim zweiten Zug der ersten Rohrlänge die Ziehgeschwindigkeit gegen Ende des Zuges manuell abgesenkt wird und die Länge des bis zum Absenkzeitpunkt gezogenen Rohres gemessen und registriert wird, daß aus der Differenz des Meßwertes aus dem ersten Zug und dem Meßwert des zweiten Zuges ein Koeffizient als Maß für die gefahrene Verlängerung des Rohres und den aktuellen Werkzeugzustand errechnet wird, aus dem die Absenkpunkte für die Ziehgeschwindigkeit der nachfolgenden zweiten Züge der folgenden Rohrlängen errechnet werden. <IMAGE>

Abstract: The steps of the escalator move along a curved path which has a fixed constant radius when viewed in plan. The step chain also follows the constant radius path and thus its effective length must vary at different locations along its path of travel in order to keep the step rollers on their constant radius tracks. The effective length of the step chain is varied by using an eccentric cam (35) at chain link connections spaced along the chain whereby the degree of overlap of adjacent links (25,26) can be changed by controlling the path along which cam actuating rollers (41,42) travel. The cam actuating rollers (41,42) control operation of the eccentric cam (35) link connections.

Abstract: Values which can be correlated with the physical quality features of staple length or fibre damage (QB) respectively and, if appropriate, also nep number (QVIN) are determined by frequency analysis from optical brightness measurements which are carried out on-line on the card web (F), for example on the cylinder surface. The frequency analysis is conducted preferably by means of band-pass filters which filter out frequency bands from the frequency spectrum (A, B) of the measurement signal supplied by the optical sensors (11). The optical measurements are conducted on local and time-related samples of the web (F), and the values determined by the frequency analysis are averaged locally and in time. The output values of the frequency analysis, which are additionally processed if appropriate, are displayed and are used for the personal monitoring of the card. They can also be processed into alarm signals (16) and into control variables and can be used for an automatic control or regulation of the card parameters. Advantageously used for the optical measurements is a plurality of optical sensors (11.1, 11.2, 11.3, 11.4) which are arranged distributed over the web width and which are connected via a slow-acting multiplexer (40) together with a single electronic circuit for the further processing of the signals. <IMAGE>
