Description
Die Erfindung betrifft eine Ringspinnvorrichtung mit wenigstens einer Spinnstelle, die ein Streckwerk und eine Ringspindel enthält, wobei eine Falschdralleinrichtung für einen zu verdrehenden Faserverband zwischen Streckwerk und Ringspindel angeordnet ist, an die der Faserverband seitlich anlegbar ist.The invention relates to a ring spinning device with at least one spinning station, which includes a drafting system and a ring spindle, wherein a false twisting device is arranged for a twisting fiber structure between drafting and ring spindle, to which the fiber structure is applied laterally.
Eine derartige Ringspinnvorrichtung ist aus der
Die meisten Fadenbrüche entstehen beim Ringspinnen im Bereich unmittelbar im Anschluss an das Ausgangswalzenpaar des Streckwerks, wenn der zu verdrehende Faserverband die Ausgangsklemmlinie verlässt. Dort kann ein so genanntes Spinndreieck vorhanden sein, das eine Schwachstelle des Faserverbandes auf seinem Weg zur Ringspindel darstellt. Die Drehungsfortpflanzung in dem Faserverband wird, ausgehend von der Ringspindel, oftmals auch dadurch behindert, dass zwischen Ausgangswalze des Streckwerks und Ringspindel ein Fadenführer angeordnet ist. Dieser Fadenführer wird auch als "Sauschwänzchen" bezeichnet.Most yarn breaks occur in ring spinning in the area immediately following the pair of output rollers of the drafting system when the fiber strand to be twisted leaves the output clamping line. There, a so-called spin triangle may be present, which represents a weak point of the fiber structure on its way to the ring spindle. The rotation propagation in the fiber structure, starting from the ring spindle, often also hindered by the fact that a thread guide is arranged between the output roller of the drafting and ring spindle. This thread guide is also called "Sauschwänzchen".
Durch eine Falschdralleinrichtung zwischen Streckwerk und Ringspindel kann die Drehung des Faserverbandes unmittelbar im Anschluss an die Ausgangsklemmlinie, also insbesondere im Bereich eines Spinndreiecks, erhöht werden, so dass sich die Zahl der Fadenbrüche verringern lässt. Die aus
Es sind auch Falschdralleinrichtungen verschiedener Art bekannt, die ohne Unterdruckversorgung arbeiten. Diese Falschdralleinrichtungen weisen rotierende Elemente auf, die eine Öffnung für den Faserverband enthalten. Bei der Behebung eines Fadenbruchs muss der Faden durch die Öffnung der Falschdrallelemente hindurchgefädelt werden. Der Aufwand für die Behebung eines Fadenbruchs ist dadurch wesentlich erhöht. Insgesamt kann der Bedien- und Wartungsaufwand der Ringspinnmaschine durch derartige Falschdralleinrichtungen nicht verringert werden, selbst wenn sich die Anzahl der Fadenbrüche reduziert.There are also false twisting devices of various types known that work without vacuum supply. These false twist devices have rotating elements which contain an opening for the fiber structure. When eliminating a thread breakage, the thread must be threaded through the opening of the false twist elements. The cost of repairing a thread breakage is thereby substantially increased. Overall, the operating and maintenance costs of the ring spinning machine can not be reduced by such false-twisting devices, even if the number of yarn breaks is reduced.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Falschdralleinrichtung für eine Ringspinnvorrichtung zu schaffen.The invention has for its object to provide an improved false twist device for a ring spinning device.
Die Aufgabe gemäß Anspruch 1 gelöst.The object is achieved according to
Der zu verdrehende Faserband liegt auf der Reibfläche der rotierenden Scheiben auf und wird durch die Reibfläche um sich selbst verdreht und erhält dadurch einen Falschdrall. Im Vergleich zu einer pneumatischen Falschdralleinrichtung ist für die Falschdralleinrichtung wesentlich weniger Energieeinsatz erforderlich. Bei einer Behebung eines Fadenbruchs, also beim Anspinnen der Spinnstelle, ist kein erhöhter Arbeitsaufwand erforderlich. Der zu verdrehende Faserverband legt sich von selbst an die Reibfläche der rotierbaren Scheibe an. Es ist kein Einfädeln erforderlich. Die Reibfläche ist bevorzugt am Außenumfang der Scheibe angeordnet.The sliver to be twisted rests on the friction surface of the rotating disks and is rotated around itself by the friction surface and thus receives a false twist. Compared to a pneumatic false twist device much less energy input is required for the false twist device. When correcting a thread break, so when piecing the spinning station, no increased workload is required. The fiber strand to be twisted applies itself to the friction surface of the rotatable disc. There is no threading required. The friction surface is preferably arranged on the outer circumference of the disc.
Es ist vorteilhaft, dass die Rotationsrichtung der Scheibe so gerichtet ist, dass der Faserverband durch die Falschdralleinrichtung in der gleichen Drehrichtung gedreht wird, wie durch die Ringspindel. Die Drehung des Faserverbandes lässt sich temporär erhöhen, so dass die Gefahr eines Fadenbruchs sich verringert. Insbesondere lässt sich die Drehung des Faserverbandes in dem Bereich zwischen der Ausgangsklemmlinie des Streckwerks und der Falschdralleinrichtung erhöhen. Die Festigkeit des Faserverbandes in seinem schwächsten Bereich unmittelbar im Anschluss an die Ausgangsklemmlinie, wo sich auch das Spinndreieck befindet, wird dadurch erhöht.It is advantageous that the direction of rotation of the disc is directed so that the fiber structure is rotated by the false twist device in the same direction of rotation, as by the ring spindle. The rotation of the fiber structure can be temporarily increased, so that the risk of yarn breakage is reduced. In particular, the rotation of the fiber structure in the region between the output clamping line of the drafting system and the false twist device can be increased. The strength of the fiber structure in its weakest area immediately after the Ausgangsklemmlinie, where the spinning triangle is located, is thereby increased.
Es ist vorteilhaft, dass der Faserverband durch die zwei benachbarten Scheiben geführt wird, so dass solche mit einem Achsabstand angeordnet sind, der kleiner als der Scheibendurchmesser ist. Zwei benachbarte Scheiben überlappen sich, und es entsteht ein Keilspalt. Der Faserverband legt sich in den Keilspalt der beiden benachbarten Scheiben und wird dort sicher positioniert. Durch die Reibflächen der beiden Scheiben wird dem Faserverband eine Drehung erteilt. Die benachbarten Scheiben rotieren gleichsinnig.It is advantageous that the fiber bundle is passed through the two adjacent discs, so that those are arranged with an axial distance which is smaller than the disc diameter. Two adjacent disks overlap and a wedge gap is created. The fiber structure settles in the wedge gap of the two adjacent disks and is securely positioned there. Through the friction surfaces of the two discs, the fiber structure is given a rotation. The adjacent discs rotate in the same direction.
Um eine gute Auflage des Faserverbandes auf der Reibfläche und somit eine sichere Drehungserteilung zu gewährleisten, ist es vorteilhaft, dass die Falschdralleinrichtung so zwischen einer Ausgangsklemmlinie des Streckwerks und einem der Ringspindel vorgeordneten Fadenführer angeordnet ist, dass der Faserverband durch die Falschdralleinrichtung aus der kürzesten Verbindungslinie zwischen Ausgangsklemmlinie und Fadenführer ausgelenkt wird. Diese Anordnung ist insbesondere vorteilhaft, wenn der Faserverband in dem Keilspalt von den zwei benachbarten Scheiben geführt wird.In order to ensure a good circulation of the fiber structure on the friction surface and thus a reliable rotation distribution, it is advantageous that the false twisting device is arranged between an output clamping line of the drafting system and one of the ring spindle upstream yarn guide, that the fiber structure by the false twisting device from the shortest connecting line between Output terminal line and thread guide is deflected. This arrangement is particularly advantageous when the fiber structure in the wedge gap is guided by the two adjacent disks.
In Ausgestaltung der Erfindung kann es vorteilhaft sein, dass der Scheibendurchmesser der rotierbaren Scheiben größer ist als die Teilung der Ringspinnvorrichtung. Die Anzahl der Scheiben in der Ringspinnvorrichtung ist dann um eine Scheibe höher als die Anzahl der nebeneinander angeordneten Spinnstellen. Diese Ausgestaltung ist insbesondere dann vorteilhaft, wenn die Teilung der Ringspinnvorrichtung, also der Abstand von Spinnstelle zu Spinnstelle, sehr klein ist, wie es häufig bei der Verarbeitung von Kurzstapelfasern üblich ist.In an embodiment of the invention, it may be advantageous that the disk diameter of the rotatable disks is greater than the pitch of the ring spinning device. The number of discs in the ring spinning device is then one slice higher than the number of juxtaposed spinning stations. This embodiment is particularly advantageous if the Division of the ring spinning device, so the distance from spinning station to spinning station is very small, as is common in the processing of short staple fibers.

Der Ringspindel 5 ist ein Spinnring 11 und ein Ringläufer 12 zugeordnet. Der Ringspindel 5 ist ein Fadenführer 13 vorgeordnet, der auch als "Sauschwänzchen" bezeichnet wird. Der vom Streckwerk 3 gelieferte Faserverband 8 durchläuft den Fadenführer 13 und den Läufer 12 und wird auf den Kops aufgewunden. Dabei wird dem Faserverband 8 in an sich bekannter Weise seine Spindrehung erteilt. Die Spinndrehung läuft entgegen der Transportrichtung A bis zum Ausgangswalzenpaar 6,7 des Streckwerks 3 zurück. In dem Bereich unmittelbar im Anschluss an die Ausgangsklemmlinie 9 kann ein Spinndreieck vorhanden sein, das die schwächste Stelle des Faserverbandes zwischen Ausgangsklemmlinie 9 und Ringspindel 5 darstellt. Durch die Reibung des Faserverbandes 8 an dem Fadenführer 13 wird das Zurücklaufen der Spinndrehung zum Streckwerk 3 behindert.The
