Description
Uellen 14 der Spinnmaschine vorbei. Während dieser Bewegung der Reinigungsvorrichtung 10 tastet der elektrooptische Abiaster 42 den Faden 11 der betreffenden Spinnstelle 14 ab, um festzustellen, ob Fadenbrüche aufgetreten sind. Ist ein Faden 11 gerissen, wie es in F i g. 4 gezeigt, ist, so erzeugt der eiektrooptische Abt^ter 42 ein Signal, das ein elektromagnetisch gesteuertes Ventil betätigt, und der Druckhiftdüse 44 kurzzeitig ein Druckluftstrom zugeführt wild. Die Druckluftdüse 44 ist so angeonJnet, daß der von ihr abgegebene Druckluftstrom auf die Auslöseplatte 50 trifft. Nach F i g. 4 überwindet der Druckluftstrom die Haltekra ι der Feder 58 des Federraststifts 56 und verschwenkt die Auslöseplatte 50 im Uhrzeigersinn. Sobald der Federraststift 56 außer Eingriff mit dem Hals 60 steht, dreh; sich der halbzylindrische Abschnitt 46 der Fadenbremse 45 zusammen mit der Eingangsunterwalze 22, und die Vorderkante 62 des Abschnitts 46 wird in den Spalt zwischen den Eingangswalzen 20 und 22 eingeführt. Hierdurch wird die Eingangsoberwalze 20 von der sie antreibenden Eingangsunterwalze 22 abgehoben und so die Zufuhr weiterhin zu verarbeitenden Materials unterbrochen.Uellen 14 over the spinning machine. During this Movement of the cleaning device 10, the electro-optical Abiaster 42 scans the thread 11 of the relevant Spinning position 14 to determine whether thread breaks have occurred. If a thread 11 is broken, as shown in FIG. 4, the electro-optical Abt ^ ter 42 a signal that actuates an electromagnetically controlled valve, and the pressure shift nozzle 44 briefly a stream of compressed air supplied wild. The compressed air nozzle 44 is designed so that the compressed air flow emitted by it hits the trigger plate 50. According to FIG. 4 overcomes the Compressed air flow holds the spring 58 of the spring detent pin 56 and pivots the release plate 50 clockwise. Once the spring detent pin 56 is out of engagement with the neck 60, rotate; himself the semi-cylindrical portion 46 of the thread brake 45 together with the input lower roller 22, and the Leading edge 62 of section 46 is inserted into the nip between input rollers 20 and 22. As a result, the upper input roller 20 is lifted from the lower input roller 22 which drives it and so the supply of material to be processed is interrupted.
Die F i g. 7 bis 9 zeigen eine weitere Ausführung*- form der Erfindung mit einer anders ausgebildeten Fadenbremse 75. Nach F i g. 9 umfaßt die Fadenbremse 75 ebenfalls einen halbzylindrischen Abschnitt 46. an den sich ein federnder Arm 64 anschließt, von dem zwei Ansätze 66 und 68 ausgehen und eine Auslöseplatte 70 in den freien Endei* dieser Ansätze mit einem Lagerslift 72 drehbar gelagert ist. Der Arm 64 weist außerdem einen abgewinkelten Abschnitt 74 auf, der das Drehen der Auslöseplatte 70 gegen den Uhrzeigersinn verhindert. Das untere Ende "der Auslöseplatte 70 trägt einen FederraststiftThe F i g. 7 to 9 show a further embodiment * - form of the invention with a differently designed one Thread brake 75. According to FIG. 9, the thread brake 75 also comprises a semi-cylindrical section 46. to which a resilient arm 64 connects, from which two lugs 66 and 68 extend and a release plate 70 in the free end of these Approaches with a storage lift 72 is rotatably mounted. The arm 64 also has an angled one Section 74, which prevents the rotation of the trip plate 70 counterclockwise. The lower The end "of the release plate 70 carries a spring locking pin

Ebenso wie bei der Ausführungsform nach den Fig. 1 bis 6 kann bei Fadenbruch auf die Auslöseplatte 70 ein Druckluftstrorr. aus der Düse 44 gerichtet werden. Beim Auftreffen des Druckluftstroms auf die Auslöseplatte 70 wird diese unter Ausfedem des Armes 64 um den Lagerr'ft 72 im Uhrzeigersinn verschwenkt und der Fedeivartstift 76 gerät außer Eingriff mit dem Hals 60 der Eingangsoberwalze 20, so daß sich die Fadenbremse 75 zusammen mit der Eingangsunterwalze 22 gegen den Uhrzeigersinn drehen kann. Die Vorderkante 62 des Abschnitts 46 gerät nun in den Spalt des Eingangswalzenpaares 20, 22, hebt die Eingangsoberwalze 20 von der Eingan gsunterwalze 22 ab und unterbricht so die Zufuhr weiteren zu verarbeitenden Materials.As with the embodiment according to FIGS. 1 to 6, the release plate can be opened in the event of a thread breakage 70 a compressed air flow. directed from the nozzle 44. When the compressed air flow hits the release plate 70 is this under Ausfedem of The arm 64 is pivoted clockwise about the bearing rod 72 and the spring-loaded articulating pin 76 goes out of action Engage with the neck 60 of the input top roller 20, so that the thread brake 75 together with the Input lower roller 22 can rotate counterclockwise. The leading edge 62 of section 46 is device now in the gap of the input roller pair 20, 22, the input top roller 20 lifts from the input gsunterwalze 22 and interrupts the supply of further material to be processed.
