Description

Vorliegende Erfindung betrifft einen Fadenspanner insbesondere zur Ver­ wendung in der Textilindustrie, wie z. B. in der Hauptanmeldung P 37 33 690.8 beschrieben.The present invention relates to a thread tensioner, in particular for ver application in the textile industry, such as B. in the main application P 37 33 690.8 described.

Der Aufbau der Fadenspanner, aus preislichen Gründen bisher auf einfachen Blechplatten montiert, hat den Nachteil der Verschmutzung der freiliegenden Regelteile durch Flusen und Glasstaub, die die dauerhafte Funktion beein­ trächtigen sowie der leichten Verbiegbarkeit, wenn Anpreßrollen aufein­ ander wirken, deren Spaltbildung äußerst genau sein muß.The construction of the thread tensioner, for reasons of price so far on simple Mounted sheet metal plates has the disadvantage of contamination of the exposed Control parts through fluff and glass dust, which affect the permanent function pregnant and easy to bend when pressure rollers on one another act different, the gap formation must be extremely accurate.

Erfindungsgemäß wurde diese Blechform durch ein dickwandiges, stabil her­ gestelltes Gehäuse 1 ersetzt, das durch einen dichten Deckel verschlossen wird. Dieses Gehäuse 1 ist durch Gießen, Pressen oder Fräsen genau herzu­ stellen und besitzt die erforderliche Stabilität. Er ist ferner so ausge­ bildet, daß auch die Seitenwände mit Gewinde 5 für Halterungszwecke an den Spulmaschinen oder die Aufnahme von Fadenführern oder elektrischen Kabel bzw. Steckereinrichtungen 12 möglich ist. Der Innenraum, der die Feder­ spannung 6 der Anpreßrolle 7 sowie einen Verstärker 10 für den elektroni­ schen Fadenzugkraftmesser 13 mit Anzeiger 11 und gegebenenfalls weitere automatische Verstellteile enthält, z.B. Servomotor, Anzeigelampe bei Fadenbruch (nicht dargestellt), ist absolut staubdicht und betriebssicher ab­ geschlossen. Notwendige Schlitze für Achsverschiebungen sind durch große Scheiben oder Flansche abgedeckt.According to the invention, this sheet metal shape was replaced by a thick-walled, stably manufactured housing 1 , which is closed by a tight cover. This housing 1 can be made by casting, pressing or milling and has the required stability. It is also designed so that the side walls with thread 5 for mounting purposes on the winding machines or the inclusion of thread guides or electrical cables or plug devices 12 is possible. The interior, which contains the spring tension 6 of the pressure roller 7 and an amplifier 10 for the electronic thread tension meter 13 with indicator 11 and possibly further automatic adjustment parts, for example servo motor, indicator lamp for thread breakage (not shown), is absolutely dust-proof and reliable from closed. Necessary slots for axis displacements are covered by large disks or flanges.

Die Umlenkrolle 9 hat eine geschlitzte Achse 13, winkelverdreht gezeichnet, die bei Belastung durch den Fadenzug ein paralleles Ausweichen der Rolle er­ gibt, so daß der Faden nicht zum Rande verläuft. An den Biegestellen sind DMS 14 befestigt, die in einer Brückenverstärkerschaltung für die Anzeige verwendet werden. 15 gibt die resultierende aus der Kraftrichtung des Fadenverlaufes und der Auslenkung der Meßachse, dargestellt in Abb. 2, an.The deflection roller 9 has a slotted axis 13 , drawn rotated, which gives a parallel evasion of the roller when loaded by the thread, so that the thread does not run to the edge. Strain gauges 14 are attached to the bending points and are used in a bridge amplifier circuit for the display. 15 specifies the resulting from the direction of force of the thread course and the deflection of the measuring axis, shown in Fig. 2.
