Abstract

In the article draw-off device with pairs of draw-off rollers (15, 16) which are mounted on pivoting levers (17, 18), both the minimum distance between the two rollers and a prestress taking effect on the pivoting levers and on the draw-off rollers can be continuously adjusted separately from one another. <IMAGE>

Description

Die Erfindung betrifft eine Warenabzugsvorrichtung für Flachstrickmaschinen, mit parallel zueinander und zu den Nadelbetten verlaufenden, unterhalb des zwischen den Nadelbetten bestehenden Kammspaltes angeordneten Abzugswalzenpaaren, von denen mindestens eine Abzugswalze angetrieben ist und mindestens eine auf in Richtung auf die Gegenwalze unter Vorspannung stehenden Schwenkhebeln gelagert ist.The invention relates to a goods take-off device for flat knitting machines, with pairs of draw-off rollers arranged parallel to one another and to the needle beds, below the comb gap existing between the needle beds, at least one draw-off roller being driven and at least one being mounted on pivoting levers that are pretensioned in the direction of the counter-roller.

Warenabzugsvorrichtungen der vorstehend genannten Art sind in verschiedener Ausführungsform vorbekannt, auch eine aufwendige Konstruktion, mit welcher die Vorspannung einer Abzugswalze gegenüber einer Gegenabzugswalze veränderbar ist (EP-OS 421665). Keine der eingangs genannten Warenabzugsvorrichtungen ist jedoch in ausreichendem und befriedigendem Maße an unterschiedliche, auf der Flachstrickmaschine herstellbare Gestricke anpaßbar. Der Erfindung liegt daher die Aufgabe zugrunde, eine Warenabzugsvorrichtung der eingangs genannten Art in größerem Umfange als bisher bekannte Vorrichtungen an unterschiedliche Gestricke anpaßbar zu gestalten.Goods take-off devices of the type mentioned above are known in various embodiments, also a complex construction with which the pretensioning of a take-off roller can be changed compared to a counter-take-off roller is (EP-OS 421665). However, none of the goods take-off devices mentioned at the outset can be adequately and satisfactorily adapted to different knitted fabrics which can be produced on the flat knitting machine. The invention is therefore based on the object of making a goods take-off device of the type mentioned to a greater extent than previously known devices adaptable to different knitted fabrics.

Die gestellte Aufgabe wird mit der eingangs genannten Warenabzugsvorrichtung dadurch gelöst, daß sowohl der zwischen den beiden Abzugswalzen bestehende Mindestabstand als auch die bei dem Mindestabstand bestehende Ausgangs-Vorspannung des mindestens einen eine Abzugswalze tragenden Schwenkhebels verstellbar sind.The object is achieved with the goods take-off device mentioned at the outset in that both the minimum distance existing between the two take-off rolls and the initial pre-tension existing at the minimum distance of the at least one pivot lever carrying a take-off roll are adjustable.

Bei der erfindungsgemäß ausgebildeten Warenabzugsvorrichtung läßt sich also sowohl der Mindestabstand zwischen den Walzen der Walzenpaare, als auch die Vorspannung verändern, unter welcher die Walzen in dieser Abstandslage stehen. Vorteilhafterweise können dabei beide miteinander zusammenwirkenden Abzugswalzen eines Abzugswalzenpaares einstellbar sein und hierzu zweckmäßig am Ende von Schwenkhebeln gelagert sein, die zweiarmig ausgebildet sind und an ihrem anderen Ende einen verstellbaren, den Mindestabstand zur Gegenabzugswalze bestimmenden Anschlag aufweisen. Die verstellbaren Anschläge können hierbei vorteilhafterweise durch verstell- und feststellbare Exzenterscheiben gebildet sein, die mit gegenüber den Nadelbetten stationären Gegenflächen zusammenwirken. Diese Exzenterscheiben können auf einer allen Schwenkhebeln einer Vorrichtungshälfte gemeinsamen Stellwelle angeordnet sein.In the goods take-off device designed according to the invention, both the minimum distance between the rollers of the roller pairs and the pretension under which the rollers are in this distance position can be changed. Advantageously, both interacting take-off rollers of a pair of take-off rollers can be adjustable and, for this purpose, can be expediently mounted at the end of swivel levers which are designed with two arms and have an adjustable stop at their other end which determines the minimum distance from the counter-extraction roller. The adjustable stops can advantageously be formed by adjustable and lockable eccentric disks which cooperate with counter surfaces which are stationary with respect to the needle beds. These Eccentric discs can be arranged on an actuating shaft common to all pivot levers of one device half.

Die Einstellbarkeit der Vorspannung der Schwenkhebel und damit der an ihnen gelagerten Abzugswalzen kann in an sich bekannter Weise mittels einer Feder bewirkt sein. Diese Feder kann auf einfache Weise mit ihrem einen Ende an dem Schwenkhebel und mit ihrem anderen Ende an einem verstellbaren Widerlager angreifen. Es kann hier auch auf gesonderte Zug- oder Druckfedern verzichtet werden und die einstellbare Vorspannung durch einen elastisch biegbaren Arm des Schwenkhebels bewirkt sein, der mittels eines verstellbaren Spannkörpers, insbesondere einer bereits erwähnten Exzenterscheibe, beaufschlagbar ist.The adjustability of the pretension of the swivel levers and thus of the take-off rollers mounted on them can be effected in a manner known per se by means of a spring. This spring can easily engage with one end on the pivot lever and with its other end on an adjustable abutment. Separate tension or compression springs can also be dispensed with here and the adjustable pretension can be brought about by an elastically bendable arm of the pivoting lever, which can be acted upon by means of an adjustable tensioning body, in particular an already mentioned eccentric disk.

Durch die gesonderte Verstellbarkeit des gegenseitigen Mindestabstandes der Abzugswalzen und ihrer Vorspannung, und dies insbesondere für beide Walzen eines Abzugswalzenpaares, läßt sich die Warenabzugsvorrichtung gemäß der Erfindung sehr feinfühlig an unterschiedliche Gestrickarten anpassen und während des Betriebs der Flachstrickmaschine einjustieren.Due to the separate adjustability of the mutual minimum distance between the draw-off rollers and their pretension, and this in particular for both rollers of a pair of draw-off rollers, the goods take-off device according to the invention can be very sensitively adapted to different types of knitted fabrics and adjusted during operation of the flat knitting machine.

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Warenabzugsvorrichtung anhand der beiliegenden Zeichnung näher erläutert.An exemplary embodiment of a goods take-off device designed according to the invention is explained in more detail below with reference to the accompanying drawing.

Die Schnittdarstellung der Fig. 1 zeigt die Träger 10 und 11 für die beiden Nadelbetten einer Flachstrickmaschine, in denen die nicht dargestellten Nadeln in den durch strichpunktierte Linien 12 und 13 gekennzeichneten und sich kreuzenden Ebenen angeordnet sind. Unterhalb dieser beiden Ebenen 12 und 13 ist in dem als Kammspalt bezeichneten Zwischenraum 14 zwischen den beiden Nadelbetten eine Warenabzugsvorrichtung angeordnet, die in bekannter Weise aus mindestens einem Paar von parallel zueinander verlaufenden und mit einer profilierten Oberfläche versehenen, angetriebenen Abzugswalzen 15, 16 besteht. Das nicht dargestellte, mit den Nadeln der beiden Nadelbetten gefertigte Gestrick läuft zwischen die beiden Abzugswalzen 15, 16 ein, wird von ihnen erfaßt und nach unten unter Spannung abgezogen. Die beiden miteinander zusammenwirkenden Abzugswalzen 15 und 16 sind jeweils am einen Ende von zweiarmigen Schwenkhebeln 17 und 18 gelagert, die in ihrem Mittelteil jeweils um eine Achse 19 oder 20 auf einem Tragarm 21 oder 22 verschwenkbar sind, der auf der Unterseite eines Nadelbettträgers 10 oder 11 befestigt ist. An dem der Abzugswalze 15 oder 16 entgegengesetzten, in der Zeichnung unteren Ende der Schwenkhebel 17 und 18 ist jeweils eine Stellwelle 23 oder 24 gelagert, auf welcher eine Exzenterscheibe 25 oder 26 befestigt ist. Diese Exzenterscheibe 25 oder 26 bildet einen Anschlag des Schwenkhebels 17 oder 18, der mit einer Gegenanschlagsfläche 27 oder 28 an dem stationären Tragarm 21 oder 22 zusammenwirkt. Durch Drehen der Stellwellen 23 und 24, die über die ganze Länge der Nadelbetten durchgehende gemeinsame Stellwellen sein können, läßt sich ein erwünschter Mindestabstand zwischen den beiden Abzugswalzen 15 und 16 in Anpassung an die Stärke und die Art des abzuziehenden Gestrickes stufenlos einstellen. Anderseits lassen sich die beiden Abzugswalzen 15 und 16 auseinanderbewegen, jedoch nur gegen eine auf die Schwenkhebel 17 und 18 wirkende Federvorspannkraft. Die Vorspanneinrichtung ist in Fig. 1 aus Gründen der besseren Übersichtigkeit nicht dargestellt, jedoch aus Fig. 2 ersichtlich.The sectional view of FIG. 1 shows the carriers 10 and 11 for the two needle beds of a flat knitting machine, in which the needles, not shown, are arranged in the intersecting planes indicated by dash-dotted lines 12 and 13. Below these two planes 12 and 13, a goods take-off device is arranged in the space 14, which is referred to as a comb gap, between the two needle beds, which device consists, in a known manner, of at least one pair of driven take-off rolls 15, 16 running parallel to one another and provided with a profiled surface. The knitted fabric, not shown, made with the needles of the two needle beds runs between the two draw-off rollers 15, 16, is grasped by them and under tension downwards deducted. The two interacting take-off rollers 15 and 16 are each supported at one end by two-armed pivot levers 17 and 18, which in their central part can each be pivoted about an axis 19 or 20 on a support arm 21 or 22 which is on the underside of a needle bed carrier 10 or 11 is attached. An actuating shaft 23 or 24, on which an eccentric disk 25 or 26 is fastened, is respectively mounted on the lower end of the pivot levers 17 and 18 opposite the draw-off roller 15 or 16. This eccentric disc 25 or 26 forms a stop of the pivot lever 17 or 18, which cooperates with a counter stop surface 27 or 28 on the stationary support arm 21 or 22. By turning the control shafts 23 and 24, which can be continuous control shafts over the entire length of the needle beds, a desired minimum distance between the two take-off rollers 15 and 16 can be continuously adjusted to match the strength and the type of knitted fabric to be drawn off. On the other hand, the two take-off rollers 15 and 16 can be moved apart, but only against a spring biasing force acting on the pivot levers 17 and 18. The pretensioning device is not shown in FIG. 1 for reasons of better clarity, but can be seen from FIG. 2.

In Fig. 2 sind die beiden Schwenkhebel 17 und 18 und damit die in ihnen gelagerten Abzugswalzen 15 und 16 auseinandergeschwenkt. Die Vorspannkraft, die hierbei überwunden werden muß, wird bei dem in Fig. 1 und 2 dargestellten Ausführungsbeispiel durch eine Druckfeder 29 bewirkt, die bei dem Schwenkhebel 17 mit ihrem einen Ende 29.1 an dem die Stellwelle 23 tragenden unteren Arm dieses Schwenkhebels und mit ihrem anderen Ende 29.2 an einem Spannhebel 30 befestigt ist. Der Spannhebel 30 ist an dem Träger 21 um eine Achse 31 verschwenkbar gelagert und weist an seinem unteren Ende eine Rolle 32 auf, mit welcher er gegen eine Exzenterscheibe 33 anliegt. Die Exzenterscheibe 33 ist auf einer zweiten Stellwelle 34 befestigt, die wie die Stellwellen 23 und 24 über die Länge der Nadelbetten durchgehend und mehreren Spannhebeln gemeinsam sein kann. Durch Drehen der Stellwelle 34 und damit der Exzenterscheibe 33 läßt sich die Schwenklage des Spannhebels 30 verändern und dabei durch die Änderung der Entfernung der beiden Enden 29.1 und 29.2 der Spannfeder 29 deren auf den Schwenkhebel 17 im Uhrzeigersinne wirksame Vorspannkraft. Der die andere Abzugswalze 16 tragende Schwenkhebel 18 ist mit einer genau gleich aufgebauten Vorspanneinrichtung versehen, deren Teile mit den gleichen Bezugsziffern, ergänzt durch einen Indexstrich, bezeichnet sind.In Fig. 2, the two pivot levers 17 and 18 and thus the discharge rollers 15 and 16 mounted in them are pivoted apart. The biasing force that must be overcome here is effected in the embodiment shown in FIGS. 1 and 2 by a compression spring 29, which in the pivot lever 17 with one end 29.1 on the the actuating shaft 23 supporting lower arm of this pivot lever and is attached at its other end 29.2 to a clamping lever 30. The tensioning lever 30 is mounted on the carrier 21 so as to be pivotable about an axis 31 and has a roller 32 at its lower end with which it rests against an eccentric disk 33. The eccentric disk 33 is fastened on a second adjusting shaft 34 which, like the adjusting shafts 23 and 24, can be continuous over the length of the needle beds and can be common to several tensioning levers. By turning the adjusting shaft 34 and thus the eccentric disc 33, the pivoting position of the tensioning lever 30 can be changed and, by changing the distance between the two ends 29.1 and 29.2 of the tensioning spring 29, its pretensioning force acting on the pivoting lever 17 in the clockwise direction. The swivel lever 18 carrying the other take-off roller 16 is provided with a pretensioning device of exactly the same construction, the parts of which are designated by the same reference numbers, supplemented by an index line.

Fig. 3 zeigt teilweise eine Warenabzugsvorrichtung, die sich durch die Ausbildung ihrer Vorspanneinrichtung von der Ausführungsform nach Fig. 1 und 2 unterscheidet. Der eine Abzugswalze 35 tragende Schwenkhebel 37 ist wie der Schwenkhebel 17 zweiarmig ausgebildet und in seinem Mittelbereich um eine Achse 39 auf einem stationären Träger 41 gelagert. Wie der Schwenkhebel 17 trägt er an seinem unteren Ende eine mit einer Exzenterscheibe 45 versehene Stellwelle 43, und die Exzenterscheibe 45 bildet einen Anschlag des Schwenkhebels 37 an einer Gegenanschlagfläche 47 des Trägers 41. Der Schwenkhebel 37 weist als dritten Arm einen Federsteg 50 auf, auf dessen freien Endbereich als Spannorgan eine Exzenterscheibe 53 einwirkt, die auf einer zweiten Stellwelle 54, die der Stellwelle 34 beim Ausführungsbeispiel nach Fig. 1 und 2 entspricht, befestigt ist. Durch die Exzenterscheibe 53 läßt sich der Federsteg 50 elastisch ausbiegen und dadurch die auf die Abzugswalze 35 einwirkende Vorspannung verändern.FIG. 3 partially shows a goods take-off device which differs from the embodiment according to FIGS. 1 and 2 by the design of its pretensioning device. The pivot lever 37 carrying a take-off roller 35 is designed like the pivot lever 17 with two arms and is mounted on a stationary support 41 in its central region around an axis 39. Like the pivot lever 17, it carries at its lower end an adjusting shaft 43 provided with an eccentric disk 45, and the eccentric disk 45 forms a stop for the pivot lever 37 on a counter stop surface 47 of the carrier 41. The pivot lever 37 has a spring bar 50 as a third arm whose free end area acts as a tensioning member an eccentric 53 a second actuating shaft 54, which corresponds to the actuating shaft 34 in the exemplary embodiment according to FIGS. 1 and 2, is fastened. By means of the eccentric disc 53, the spring bar 50 can be elastically bent out and thereby change the pretension acting on the take-off roller 35.
