Description
Die Erfindung bezieht sich auf eine Warenabzugseinrichtung an Flachstrickmaschinen, mit einer angetriebenen, aus mehreren Walzenelementen bestehenden Warenabzugswalze und mit den Walzenelementen zugeordneten Andruckrllen einer Warenandruckwalze, die auf einer gemeinsamen Schwenkwelle sitzen und einstellbar federnd gegen das jeweilige Walzenelement drückbar sind.The invention relates to a goods take-off device on flat knitting machines, with a driven goods take-off roller consisting of a plurality of roller elements and with the pressure elements of a material pressure roller assigned to the roller elements, which are seated on a common swivel shaft and can be pressed resiliently against the respective roller element.
Eine ähnliche Warenabzugseinrichtung, bei der jedoch die Warenabzugswalze einstückig ausgebildet ist, ist aus der DE-C- 651 296 bekannt. Ein Antrieb der einstückigen Warenabzugswalze ist dort nicht zu erkennen.A similar goods take-off device, in which, however, the goods take-off roller is made in one piece, is known from DE-C-651 296. A drive of the one-piece goods take-off roller cannot be seen there.
Weiter ist durch die FR-A- 972 602 bekannt geworden, einen von einer Jacquardeinrichtung intermittierend gesteuerten Elektromagneten vorzusehen, der im jeweils eingeschalteten Zustand über ein Hebelgestänge mehrere Andruckrollen gemeinsam von einer einstückigen Warenabzugswalze abhebt.It has also become known from FR-A-972 602 to provide an electromagnet which is intermittently controlled by a jacquard device and which, when switched on, lifts several pressure rollers together from a one-piece goods take-off roller via a lever linkage.
Die am häufigsten verwendeten Warenabzugseinrichtungen an Flachstrickmaschinen weisen im allgemeinen eine Warenabzugswalze und eine Warenandruckwalze auf. Das Gestrick, das von den Nadeln kommend zwischen den beiden Walzen hindurchläuft, wird von einer angetriebenen Warenabzugswalze gezogen. Die Warenandruckwalze hat die Aufgabe, das Gestrick an die Warenabzugswalze anzudrücken und den Umschlingungswinkel, den das Gestrick um die Warenabzugswalze durchläuft, festzulegen.The most frequently used goods take-off devices on flat knitting machines generally have a goods take-off roller and a goods pressure roller. The knitted fabric, which comes from the needles between the two rollers, is pulled by a driven goods take-off roller. The The material pressure roller has the task of pressing the knitted fabric onto the fabric take-off roller and of determining the wrap angle through which the fabric knits around the fabric take-off roller.
Damit der Warenabzug optimiert werden kann, besteht die Warenabzugswalze, wie beispielsweise aus der DE-PS 33 31 052 bekannt, aus einer der Nadelraumbreite entsprechenden Anzahl kurzer Walzenelemente, die unabhängig voneinander über einen bestimmten Drehwinkel federbelastet die Gestrickabzugskraft unterschiedlich beeinflussen. Die Warenandruckwalze weist ihrerseits federnd gegen die jeweiligen Walzenelemente drückbare Andruckrollen auf.So that the take-off can be optimized, the take-off roller, as is known for example from DE-PS 33 31 052, consists of a number of short roller elements corresponding to the width of the needle space, which independently of one another influence the knitted pull-off force in a spring-loaded manner over a certain angle of rotation. The goods pressure roller in turn has pressure rollers which can be pressed resiliently against the respective roller elements.
Um beim Stricken einen gleichmäßigen Gestrickabzug zu erhalten, müssen die Andruckrollen mehr oder weniger unterschiedlich in ihrer Andruckkraft justiert werden.In order to obtain a uniform knitted fabric pull-off, the pressure rollers have to be adjusted more or less differently in terms of their pressure force.
Die Justierung richtet sich nach dem zu verarbeitenden Garn und der Bindung des Gestricks, das abgezogen werden soll. Wenn die Andruckrollen so eingestellt sind, daß das Gestrick gleichmäßig abgezogen wird, wobei die Maschenreihen waagerecht ohne Bogen die Warenabzugseinrichtung verlassen, und anschließend die gesamte Andruckkraft gleichmäßig verändert werden muß, so müssen sämtliche Andruckrollen parallel verstellt und neu justiert werden.The adjustment depends on the yarn to be processed and the binding of the knitted fabric that is to be pulled off. If the pinch rollers are adjusted so that the knitted fabric is pulled off evenly, the rows of stitches leaving the goods take-off device horizontally without a bow, and then the total pressure force has to be changed evenly, all pinch rollers must be adjusted in parallel and readjusted.
Der Erfindung liegt die Aufgabe zugrunde, eine Warenabzugseinrichtung der eingangs beschriebenen Art zu schaffen, mit welcher ein automatisch einstellbarer, reproduzierbar gleichmäßiger Gestrickabzug erhalten wird.The invention has for its object to provide a goods take-off device of the type described in the introduction with which an automatically adjustable, reproducibly uniform knitted fabric take-off is obtained.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Andruckrollen elektromotorisch gemeinsam in variable Endstellungen einschwenkbar und aus diesen ausschwenkbar sind, und daß die Anpreßkraft jeder Andruckrolle einzeln elektromotorisch verstellbar ist.This object is achieved in that the pressure rollers can be pivoted together and pivoted out of variable end positions by means of an electric motor, and that the contact pressure of each pressure roller can be adjusted individually by means of an electric motor.
Weiterbildungen der Erfindung bestehen darin, daß die Drehachse der Schwenkrolle gegenüber der Mittelachse der Warenabzugswalze prallel zu zwei Koordinatenachsen horizontal und vertikal elektromotorisch verstellbar oder auf einem Kreisbogen um die Mittelachse der Warenabzugswalze schwenkbar ist. Hiermit läßt sich der Umschlingungswinkel α, den das Gestrick um die Warenabzugswalze durchläuft, den Abzugsverhältnissen angepaßt automatisch verstellen.Further developments of the invention consist in the fact that the axis of rotation of the swivel roller can be adjusted horizontally and vertically by an electric motor parallel to two coordinate axes parallel to the central axis of the goods take-off roller or can be pivoted on an arc around the central axis of the goods take-off roller. This allows the wrap angle α, which the knitted fabric passes through the material take-off roller, to be adjusted automatically in accordance with the take-off conditions.
Vorteilhaft sind weiter die Andruckrollen jeweils einzeln elektromotorisch antreibbar.Furthermore, the pressure rollers are advantageously each individually drivable by an electric motor.
Zum Ein- und Ausschwenken der Andruckrollen ist zweckmäßig ein an der Schwenkwelle axial angeordneter Elektromotor vorgesehen.To pivot the pressure rollers in and out, an electric motor axially arranged on the pivot shaft is expediently provided.
Weiter ist vorteilhaft zum Verstellen der Anpreßkraft der Andruckrollen jeweils ein auf je eine Druckfeder wirkender Schrittmotor vorgesehen.Furthermore, a stepping motor acting on one compression spring each is advantageously provided for adjusting the contact pressure of the pressure rollers.
Zum Parallelverstellen oder Schwenken der Schwenkwelle gegenüber der Warenabzugswalze ist zweckmäßig ein mit der Schwenkwelle verbundener Elektromotor vorgesehen.An electric motor connected to the swivel shaft is expediently provided for parallel adjustment or swiveling of the swivel shaft relative to the goods take-off roller.
Weiter sind zum Antreiben der Andruckrollen vorteilhaft einzelne Schrittmotoren vorgesehen.Furthermore, individual stepping motors are advantageously provided for driving the pressure rollers.
Der Elektromotor zum Ein- und Ausschwenken, der Schrittmotor zum Verstellen der Anpreßkraft, der Elektromotor zum Parallelverstellen oder Schwenken und/oder die Schrittmotoren zum Antreiben der Andruckrollen sind vorteilhaft über eine Maschinensteuerung der Flachstrickmaschine ansteuerbar.The electric motor for swiveling in and out, the stepper motor for adjusting the contact pressure, the electric motor for parallel adjustment or swiveling and / or the stepper motors for driving the pressure rollers can advantageously be controlled via a machine control of the flat knitting machine.

- Fig 3 eine gemäß der Erfindung ausgebildete Warenabzugseinrichtung in der Stellung wie in Fig 1 dargestellt.
- 1 shows a conventional goods take-off device with a goods pressure roller resting on the goods take-off roller, schematically in cross section,
- 2 shows a goods take-off device as in FIG. 1, but with the goods pressure roller pivoted out, and
- 3 shows a goods take-off device designed according to the invention in the position shown in FIG.
Die in den Fig 1 und 2 dargestellte Warenabzugseinrichtung weist eine aus mehreren Walzenelementen bestehende Warenabzugswalze 2 sowie eine aus mehreren Ändruckrollen 3 bestehende Warenandruckwalze auf. Ein Gestrick 1, das von den nicht dargestellten Nadeln kommend zwischen beiden Walzen hindurchläuft, wird von der angetriebenen Warenabzugswalze 2 abgezogen. Die Andruckrollen 3 der Warenandruckwalze haben die Aufgabe, das Gestrick 1 an die Warenabzugswalze 2 anzudrücken und den Umschlingungswinkel α, den das Gestrick 1 um die Warenabzugswalze 2 durchläuft, festzulegen. Damit der Warenabzug optimiert werden kann, besteht die Warenabzugswalze 2 aus einer der Nadelraumbreite entsprechenden Anzahl kurzer Walzenelemente, die unabhängig voneinander über einen bestimmten Drehwinkel federbelastet die Gestrickabzugskraft unterschiedlich beeinflussen. Jedem Walzenelement ist eine Andruckrolle 3 der Warenandruckwalze zugeordnet. Die Andruckrollen 3 sind auf einer mit einem Rasthebel oder Handgriff 4 versehenen, dreh- und rastbaren Schwenkwelle 5 so angebracht, daß sie den Walzenelementen der Warenabzugswalze 2 genau gegenüberstehen. Lager 6 der Andruckrollen 3 sind mit der Schwenkwelle 5 fest verbunden. Jede Andruckrolle 3 ist mit Hilfe einer Druckfeder 7 und einer Griffschraube 8 einstellbar federbelastet.The goods take-off device shown in FIGS. 1 and 2 has a goods take-off roller 2 consisting of several roller elements and a goods pressure roller consisting of several
Die Schwenkwelle 5, die drehbar gelagert ist, nimmt zwei Positionen ein. Die eine Position ist die in Fig 2 dargestellte ausgeschwenkte Lage, in der die Andruckrollen 3 nicht an der Warenabzugswalze 2 anliegen. Die andere Position ist die in Fig 1 dargestellte Lage, in der die Andruckrollen 3 an der Warenabzugswalze 2 anliegen und in dieser Stellung gerastet gehalten werden.The
Um beim Stricken einen gleichmäßigen Gestrickabzug zu erhalten, müssen die Andruckrollen 3 mehr oder weniger unterschiedlich in ihrer Andruckkraft justiert werden. Die Justierung richtet sich nach dem zu verarbeitenden Garn und der Bindung des Gestricks das abgezogen werden soll. Die Andruckrollen 3 werden so eingestellt, daß das Gestrick 1 gleichmäßig abgezogen wird. Dies ist bestens erkennbar bei Farbringeln, wobei die Maschenreihen waagerecht ohne Bogen die Warenabzugseinrichtung verlassen müssen. Soll anschließend die gesamte Andruckkraft gleichmäßig verändert werden, dann müssen sämtliche Andruckrollen 3 parallel verstellt und neu justiert werden.In order to obtain a uniform knitted pull-off when knitting, the
Das Aus- und Einschwenken der Andruckrollen 3 erfolgt mit Hilfe des Handgriffs 4, der auf der Schwenkwelle 5 verstiftet ist, und wird von Hand ausgeführt.The

Mittels eines an der Schwenkwelle 5 axial angeordneten Elektromotors 9 lassen sich die Andruckrollen 3 gemeinsam in variable eingeschwenkte Endstellungen, wie in Fig 3 dargestellt, elektromotorisch einschwenken, so daß die Basisstellung verschieden justierter Andruckrollen 3 am Gestrick 1 entsprechend verändert werden kann. Das Ausschwenken der Andruckrollen 3 erfolgt ebenfalls gemeinsam über den Elektromotor 9.By means of an
Weiter ist jeweils ein auf je eine Druckfeder 7 jeder einzelnen Andruckrolle 3 arbeitender Schrittmotor 11 vorgesehen, durch dessen Wirkung die Anpreßkraft der Andruckrollen 3 individuell verstellbar ist.Furthermore, a
Ein mit der Schwenkwelle 5 verbundener Elektromotor 13 ermöglicht es, die Drehachse 10 der Schwenkwelle 5 gegenüber der Mittelachse 14 der Warenabzugswalze 2 entweder in zwei Koordinatenachsen horizontal und vertikal motorisch parallel zu verstellen (Doppelpfeile A), oder die Schwenkwelle 5 motorisch auf einem Kreisbogen um die Mittelachse 14 der Warenabzugswalze 2 zu schwenken (Doppelpfeile B). Damit läßt sich der Umschlingungswinkel α den Abzugsverhältnissen angepaßt automatisch und motorisch verstellen.An
Um den Abzugsverhältnissen noch weiter anpaßbare Abzugskräfte erreichen zu können, kann mit jeder der Andruckrollen 3 ein einzelner Schrittmotor 12 zum Antreiben der Andruckrollen 3 vorgesehen sein.In order to be able to achieve trigger forces which can be adjusted even further, a single stepping
