Abstract

In the tensioning device, the plurality of coaxial part rollers (14.x) of a material draw-off roller (14) can be coupled separately and selectively to a drive device (17/18). The draw-off force exerted by the individual part rollers (14.x) on a fabric web (12) depends on the prestress of a spring (20.x), the prestress of which can be varied at any time, even during the operation of the tensioning device, by means of an electrically actuable and therefore remotely controllable adjusting device (40.x). <IMAGE>

Description

Die Erfindung betrifft eine Abzugsvorrichtung für Flach­strickmaschinen, mit einer in mehrere koaxiale Teilwalzen unterteilten, mit einer Gegendruckwalze zusammenwirkenden Warenabzugswalze, wobei jede auf der gemeinsamen Achse nur in einer Richtung drehbar gelagerte Teilwalze über eine einstellbare Kupplung gesondert antreibbar und ihr ein durch einen umlaufenden Nockenstern als Antriebsorgan be­aufschlagbarer federbelasteter Schwenkhebel zugeordnet ist, der mit der Teilwalze über eine innerhalb der Teil­walze angeordnete Schlingfederkupplung in Abzugsrichtung drehfest verbunden ist.The invention relates to a take-off device for flat knitting machines, with a goods take-up roller which is divided into a plurality of coaxial partial rollers and cooperates with a counter-pressure roller, each partial roller rotatably mounted in one direction on the common axis being separately drivable via an adjustable clutch and being driven by a rotating cam star as a drive element Actuatable spring-loaded pivot lever is assigned, which is connected to the partial roller in a rotationally fixed manner in the take-off direction via a wrap spring clutch arranged within the partial roller.

Eine Abzugsvorrichtung der eingangs genannten Art ist in der DE-PS 32 17 395 vorgeschlagen worden. Bei dieser Abzugsvorrichtung kann die Vorspannung der den Schwenk­hebel einer Teilwalze belastenden Feder von Hand an der Abzugsvorrichtung selbst auf unterschiedliche Werte einge­ stellt werden. Diese Einstellung ist aber nur möglich, be­vor die Maschine in Betrieb genommen wird. Eine Verände­rung der Vorspannung während des Betriebs der Maschine ist nicht möglich.A trigger device of the type mentioned has been proposed in DE-PS 32 17 395. With this take-off device, the pretension of the spring loading the pivoting lever of a partial roller can be set to different values by hand on the take-off device itself be put. However, this setting is only possible before the machine is started up. It is not possible to change the preload while the machine is in operation.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Abzugsvorrichtung so auszubilden, daß die Vor­spannung einer jeden Teilwalze auch während des Betriebs der Flachstrickmaschine einstellbar ist.The invention is based on the object of designing the draw-off device mentioned at the outset in such a way that the pretensioning of each partial roller can also be set during operation of the flat knitting machine.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß an jeder Teilwalze die die Warenabzugskraft bestimmen­de Vorspannung der den Schwenkhebel belastenden Feder mit­tels einer fernsteuerbaren Verstellvorrichtung individuell und stufenlos einstellbar ist. Vorteilhafterweise kann hier ein elektrisch betriebenes und gesteuertes Verstell­organ eingesetzt werden, insbesondere ein Elektromotor, mit welchem ein Abstütz- oder Halteteil für die Feder ver­stellbar ist. Bei einer bevorzugten und in kleiner Bau­größe ausführbaren Ausführungsform kann der Elektromotor mit einer Gewindewelle verbunden sein, auf welcher ein mit dem Abstütz- oder Halteteil für die Feder gekoppeltes Schraubmutterteil drehfest angeordnet ist.The object is achieved according to the invention in that the pretension of the spring which loads the pivoting lever is individually and continuously adjustable on each partial roller by means of a remotely controllable adjusting device. Advantageously, an electrically operated and controlled adjusting element can be used here, in particular an electric motor, with which a support or holding part for the spring can be adjusted. In a preferred embodiment which can be carried out in a small size, the electric motor can be connected to a threaded shaft on which a screw nut part which is coupled to the support or holding part for the spring is arranged in a rotationally fixed manner.

Zur Verstellung der Abzugskraft der einzelnen Teilwalzen genügen leistungsarme kleine Regel- oder Steuermotoren, die nur zum Verstellen mit Strom versorgt werden, also nicht durch Strom dauerbelastet sind. Die Verstellstrecke des Verstellorganes kann so groß gewählt werden, daß auch eine vollständige Entspannung der Belastungsfeder und da­mit praktisch auch ein Stillsetzen der zugehörigen Teil­walze erreichbar ist.To adjust the pull-off force of the individual partial rollers, low-power small regulating or control motors are sufficient, which are only supplied with current for adjustment, and therefore are not permanently loaded by current. The adjustment distance of the adjustment element can be chosen to be so large that complete relaxation of the loading spring and thus practically also stopping of the associated partial roller can be achieved.

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

Im einzelnen zeigen:

  • Fig. 1 einen schematisierten Querschnitt durch eine V-Bett-Flachstrickmaschine mit der Abzugsvorrichtung;
  • Fig. 2 eine Seitenansicht von drei Teilwalzen der Abzugswalze, teilweise im Schnitt.
In detail show:
  • Figure 1 is a schematic cross section through a V-bed flat knitting machine with the take-off device.
  • Fig. 2 is a side view of three partial rollers of the take-off roller, partly in section.

Der schematisierte Querschnitt der Fig. 1 zeigt die beiden Nadelbetten 10 und 11 einer Flachstrickmaschine und eine auf dieser Flachstrickmaschine gefertigte Gestrickbahn 12, die sich vom Kammspalt 13 der Maschine nach unten zu einer Abzugswalze 14 erstreckt und weiter über eine Gegenwalze 15 nach unten abgeführt wird. Von der Abzugswalze 14 ist ihre Achse 16 und eine ihrer Teilwalzen 14.x ersichtlich. Die Antriebseinrichtung für die Warenabzugswalze 14 be­steht aus einer gemeinsamen Antriebswelle 17, die für jede Teilwalze 14.x einen Stern von hier durch eingesetzte Stifte 18 gebildeten Nocken aufweist, die auf einen auf der Achse 16 gelagerten zugeordneten Schwenkhebel 19.x einwirken, mit welchem eine die zugehörige Teilwalze 14.x über den Schwenkhebel 19.x in Abzugsrichtung vorspannende Druckfeder 20.x spannbar ist. Die Druckfeder 20.x ist mit ihrem in der Zeichnung oberen Ende indirekt mit dem Schwenkhebel 19.x gekoppelt, während ihr in der Zeichnung unteres Ende an einer Stützwandung 21 abgestützt ist.The schematic cross section of FIG. 1 shows the two needle beds 10 and 11 of a flat knitting machine and a knitted web 12 made on this flat knitting machine, which extends downward from the comb gap 13 of the machine to a take-off roller 14 and is further discharged downwards via a counter roller 15. Its axis 16 and one of its partial rollers 14.x can be seen from the take-off roller 14. The drive device for the goods take-off roller 14 consists of a common drive shaft 17 which, for each partial roller 14.x, has a star from cams 18 formed here by inserted pins 18, which act on an associated pivot lever 19.x mounted on the axis 16, with which one the associated partial roller 14.x can be tensioned in the pull-off direction by the compression spring 20.x via the swivel lever 19.x. The compression spring 20.x is indirectly coupled to the swivel lever 19.x with its upper end in the drawing, while its lower end in the drawing is supported on a support wall 21.

Fig. 1 zeigt noch einen Handspannhebel 23 mit einer Rück­stellfeder 24. Diese Teile gehören zu einer hier nicht dargestellten und auch nicht interessierenden Verstellvor­richtung für die gemeinsame Achse 16 aller Teilwalzen 14.x. Eine solche gemeinsame Verstelleinrichtung ist in der DE-PS 32 17 395 beschrieben.1 also shows a manual tensioning lever 23 with a return spring 24. These parts belong to an adjusting device, not shown here and also of no interest, for the common axis 16 of all the partial rollers 14.x. Such a common adjustment device is described in DE-PS 32 17 395.

In Fig. 1 ist außerdem eine Verstellvorrichtung 40.x im Schnitt dargestellt, von denen jeder Teilwalze 14.x eine eigene zugeordnet ist und mit welcher die Vorspannung der Druckfeder 20.x, welche das von der Teilwalze 14.x auf die Gestrickbahn 12 ausgeübte Warenabzugsmoment, also die auf die Gestrickbahn 12 ausgeübte Warenabzugskraft an der Teilwalze 14.x bestimmt, veränderbar ist. Die Stützwandung 21 ist am einen Ende eines zwischen zwei Wandungen 41 und 42 verdrehsicher geführten Hohlkörpers 43 ausgebildet, der in seinem anderen Ende mit einem Schraubmutterteil 44 ver­sehen ist. An den beiden Wandungen 41 und 42 ist ein Elek­tromotor 45, vorzugsweise ein Schrittmotor, befestigt, der eine Gewindewelle 46 aufweist. Die Gewindewelle 46 wirkt mit dem Schraubmutterteil 44 zusammen, so daß bei einer Drehung der Gewindewelle 46 in der einen oder anderen Richtung der Hohlkörper 43 mit der Stützwandung 21 in der Zeichnung nach oben oder unten bewegt wird. Durch die Ver­änderung der Lage der Stützwandung 21 wird die Vorspannung der Druckfeder 20.x verändert. Der Hohlkörper 43 und die Gewindewelle 46 sind mit ausreichender Länge gestaltet, so daß ein großer Verstellweg für die Stützwandung 21 gegeben ist, der so groß ist, daß die Druckfeder in der in der Zeichnung dargestellten Stellung der Verstellvorrichtung 40.x vollständig entspannt ist und daher kein Abzugsdreh­moment der Teilwalze 14.x bewirken kann.In Fig. 1, an adjusting device 40.x is also shown in section, of which each partial roller 14.x is assigned its own and with which the bias of the compression spring 20.x, which is exerted by the partial roller 14.x on the knitted web 12 Goods take-off torque, that is to say the goods take-off force exerted on the knitted web 12 on the partial roller 14.x, can be changed. The support wall 21 is formed at one end of a hollow body 43 which is guided between two walls 41 and 42 and is provided with a screw nut part 44 in its other end. An electric motor 45, preferably a stepper motor, is attached to the two walls 41 and 42 and has a threaded shaft 46. The threaded shaft 46 cooperates with the screw nut part 44, so that when the threaded shaft 46 rotates in one direction or the other, the hollow body 43 with the support wall 21 is moved up or down in the drawing. By changing the position of the support wall 21, the bias of the compression spring 20.x is changed. The hollow body 43 and the threaded shaft 46 are designed with sufficient length so that there is a large adjustment path for the support wall 21 which is so large that the compression spring is completely relaxed in the position of the adjustment device 40.x shown in the drawing and therefore no pull-off torque of the partial roller 14.x can cause.

Die Wirkung der vorgespannten Druckfeder 20.x auf die Teilwalze 14.x wird nachfolgend anhand der Fig. 2 be­schrieben. Sie zeigt drei der mit einer profilierten Ober­fläche, beispielsweise einem Gummibelag 25, versehenen Teilwalzen 14.1, 14.2 und 14.x, die ihnen zugeordneten Schwenkhebel 19.1, 19.2 und 19.x sowie die zugehörigen Nochensterne 18′ der gemeinsamen Antriebswelle 17. Jeder Schwenkhebel ist an seinem freien Ende mit einer verbrei­terten Anschlagfläche 37 für die Stifte 18 der Nocken­sterne 18′ der Antriebswelle 17 versehen und ist an seinem anderen Ende über Schrauben 26 mit einer auf der normaler­weise starr gehaltenen Achse 16 frei drehbar gelagerten Hülse 27 verbunden. Außerdem ist jeder Schwenkhebel mit einem zur Achse 16 konzentrischen Ringschild 28 verbunden, mit welchem der zwischen jeder Teilwalze 14.1 ... 14.x be­stehende Spalt 29 nach innen abgedeckt ist, um ein Ein­ziehen von Fäden in diesen Spalt zu vermeiden.The effect of the prestressed compression spring 20.x on the partial roller 14.x is described below with reference to FIG. 2. It shows three of the with a profiled surface, for example a rubber covering 25, provided partial rollers 14.1, 14.2 and 14.x, the swivel levers 19.1, 19.2 and 19.x assigned to them and the associated bone stars 18 'of the common drive shaft 17. Each swivel lever is on its free end with a widened stop surface 37 for the pins 18 of the cam stars 18 'of the drive shaft 17 and is connected at its other end via screws 26 to a sleeve 27 which is freely rotatably mounted on the axis 16 which is normally held rigidly. In addition, each pivot lever is connected to a ring shield 28 which is concentric with the axis 16 and with which the gap 29 existing between each partial roller 14.1... 14.x is covered on the inside in order to prevent threads from being drawn into this gap.

Jede Teilwalze 14.x ist durch Schrauben 30 mit einem inneren Fußring 31 fest verbunden, der auf der konzentri­schen Hülse 27 frei drehbar gelagert ist. Innerhalb jeder Teilwalze 14.1 ... 14.x befindet sich außerdem ein Kupp­lungsring 32, der über eine in eine Längsnut 33 der Achse 16 eingreifende Feder 34 drehfest mit der Achse 16 verbun­den ist.Each sub-roller 14.x is firmly connected by screws 30 to an inner foot ring 31 which is freely rotatably mounted on the concentric sleeve 27. Within each partial roller 14.1 ... 14.x there is also a coupling ring 32 which is connected to the axis 16 in a rotationally fixed manner via a spring 34 which engages in a longitudinal groove 33 of the axis 16.

Jede Teilwalze 14.x ist mit ihrem Fußring 31 einerseits über eine rechtsgängige Schlingfeder 35, die sich teils über den Fußring 31 und teils über die Hülse 27 erstreckt, mit der Hülse 27 und andererseits über eine linksgängige Schlingfeder 36, die sich teils über den Fußring 31 und teils über den Kupplungsring 32 erstreckt, mit dem Kupp­ lungsring 32 gekoppelt. Die Schlingfedern 35, 36 wirken in bekannter Weise als Einwegkupplungen. Die rechtsgängige Schlingfeder 35 bewirkt dabei, daß bei der durch die Nochensterne 17 bewirkten Verstellbewegung der Schwenk­hebel 19.1 ... 19.x im Gegenuhrzeigersinne die zugeordnete Teilwalze 14.1 ... 14.x nicht mitbewegt wird, während bei der Rückstellbewegung des Schwenkhebels 19.1 ... 19.x im Uhrzeigersinne unter dem Einfluß der vorgespannten Druck­feder 20.x die rechtsgängige Schlingfeder 35 ein Mitbewe­gen der zugeordneten Teilwalze 14.x bewirkt.Each partial roller 14.x is with its foot ring 31 on the one hand via a right-handed wrap spring 35, which extends partly over the foot ring 31 and partly over the sleeve 27, with the sleeve 27 and on the other hand via a left-hand wrap spring 36, which extends partly over the foot ring 31 and partially extends over the coupling ring 32, with the clutch tion ring 32 coupled. The wrap springs 35, 36 act in a known manner as one-way clutches. The right-hand wrap spring 35 causes the associated partial roller 14.1 ... 14.x not to be moved in the counterclockwise direction during the adjustment movement of the pivot levers 19.1 ... 19.x caused by the bone stars 17, while the return movement of the pivot lever 19.1 .. 19.x clockwise under the influence of the prestressed compression spring 20.x, the right-hand wrap spring 35 causes the associated partial roller 14.x to move along.
