Description

Die Erfindung betrifft ein Verfahren zum Vereinzeln von Textilflächen von einem Stapel und sie betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens (siehe BE-A-846 649).The invention relates to a method for separating textile areas from a stack and also relates to an apparatus for carrying out the method (see BE-A-846 649).

Bei der Herstellung von Strickwaren wie Pullovern auf Flachkulierwirkmaschinen (System Cotton) ist es erforderlich, die Rippränder oder Bündchen auf einer separaten Flach- oder Rundstrickmaschine herzustellen und an die Wirkmaschine maschengerecht zu übergeben. Bei Ripprändern handelt es sich in der Regel um zweiflächige Maschenware, die nur auf Maschinen mit zwei sich gegenüberliegenden Nadelfonturen herstellbar ist. Bekanntlich arbeiten Wirkmaschinen mit einer Nadelreihe und erzeugen demnach einflächige Maschenware.In the production of knitwear such as sweaters on flat knitting machines (System Cotton), it is necessary to produce the ribbed edges or cuffs on a separate flat or circular knitting machine and to hand them over to the knitting machine. Ribbed edges are usually double-sided knitwear that can only be produced on machines with two opposite needle contours. As is known, knitting machines work with a row of needles and therefore produce single-surface knitted fabrics.

Die Rippränder sind mit ihrer letzten gestrickten Maschenreihe auf einem Kamm aufgenadelt, d. h. die Schlinge jeder Masche der letzten gestrickten Maschenreihe hängt auf einer Nadel. Die Nadeln des Kamms werden mit den Wirknadeln der Wirkmaschine zusammengelegt und die Maschen auf diese übergestreift. Die Wirkmaschine strickt dann ab dieser übergebenen Maschenreihe weiter.The ribbed edges are needled on a comb with their last knitted course. H. the loop of each stitch in the last knitted course hangs on a needle. The needles of the comb are put together with the knitting needles of the knitting machine and the stitches are slipped onto them. The knitting machine then continues knitting from this transferred row of stitches.

In der Praxis wird auf dem Kamm aber nicht nur ein Ripprand angeordnet, da sonst für jeden Ripprand ein eigener Kamm erforderlich wäre. Hingegen werden die Rippränder zu mehreren auf einen Kamm aufgestoßen und von diesem Magazinrechen, auch Aufstoßrechen genannt, dann auf den einzelnen Strickstellen (Fonturen) in der Wirkmaschine zugeordnete ,Übertragungsrechen verteilt, während die Wirkmaschine noch an einem Strickstück arbeitet.In practice, however, not only a rib edge is arranged on the comb, since a separate comb would otherwise be required for each rib edge. On the other hand several of the rib edges pushed onto a comb and then transferred transfer rakes assigned by this magazine rake, also called push-up rake, to the individual knitting points (fonts) in the knitting machine while the knitting machine was still working on a knitted piece.

Nach Ablauf des Strickvorgangs werden für ein neues Strickstück die auf den Übertragungsrechen bereitliegenden Rippränder gleichzeitig an allen Fonturen an die Wirknadeln der Maschine übergeben.After the knitting process has been completed, the rib edges on the transfer rake are transferred to all knitting lines on the knitting needles of the machine for a new piece of knitting.

Das Übergeben der Rippränder vom Aufstoßrechen an die Übertragungsrechen der Maschine ist eine manuelle Tätigkeit, die relativ viel Zeit in Anspruch nimmt. Eine Automatisierung des Randübergebens scheiterte bisher daran, daß kein Verfahren zum Separieren der Rippränder auf dem Aufstoßrechen zur Verfügung stand, das erlaubte, jeweils nur den vorderen Ripprand eines Ränderstapels zu ergreifen und an den Übertragungsrechen zu übergeben.Passing the rip edges from the rake rake to the machine's transfer rake is a manual operation that takes a relatively long time. Automation of the edge handover has so far failed due to the fact that no method for separating the rib edges on the opening rake was available which allowed only the front rib edge of a stack of edges to be gripped and transferred to the transfer rake.

Die Schwierigkeiten beim Vereinzeln der als Stapel auf einem Rechen aufgenadelten Rippränder bestehen im wesentlichen darin, daß die freien Kanten der Rippränder in ihrer Lage weitgehend undefiniert sind, d. h. sie können wellig sein, sich in einer Richtung umlegen, wobei die Rippränder sich schuppenartig überlappen, auch können sich die Ecken der Rippränder einziehen. Diese genannten Unzulänglichkeiten behindern das Separieren von der freien Kante her, da sich keine Separierschneide zwischen die Rippränder einbringen läßt. Das Separieren von der Aufstoßrechenseite ist insofern nicht durchführbar als die Ränder zu dicht aufeinander liegen, was ein Ergreifen nur eines Randes mit einem Separierkamm erschwert.The difficulty in separating the rib edges needled as a stack on a rake consists essentially in the fact that the free edges of the rib edges are largely undefined in their position, i. H. they can be wavy, fold in one direction, the rib edges overlap like scales, and the corners of the rib edges can also contract. These shortcomings mentioned hinder the separation from the free edge, since no cutting edge can be inserted between the rib edges. It is not feasible to separate from the impact rake side insofar as the edges are too close together, which makes it difficult to grasp only one edge with a separating comb.

Die Aufgabe der Erfindung besteht darin, im Hinblick auf eine Automatisierung ein maschinelles und funktionssicher arbeitendes Verfahren zum Vereinzeln von Textilflächen von einem Stapel und eine Vorrichtung zur Durchführung des Verfahrens zu schaffen.The object of the invention is to provide, with regard to automation, a mechanical and functionally reliable method for separating textile surfaces from a stack and a device for carrying out the method.

Diese Aufgabe wird durch das Verfahren und durch die Vorrichtung mit den Merkmalen der Ansprüche 1 und 4 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the method and by the device with the features of claims 1 and 4. Advantageous refinements of the invention result from the subclaims.

Rippränder 1 für die Herstellung von Strickwaren auf Flachkulierwirkmaschinen (System Cotton) sind als Stapel auf Nadeln 2 eines Aufstoßrechens 2a aufgenadelt. Die Nadeln 2 haben einen U-förmigen Querschnitt und die offene Seite ist den Ripprändern abgewandt.Rib edges 1 for the production of knitwear on flat knitting machines (System Cotton) are needled as a stack on needles 2 of a push-up rake 2a. The needles 2 have a U-shaped cross section and the open side faces away from the rib edges.

Die Spitzen der Nadeln 2 des Aufstoßrechens 2a werden mit den Spitzen der Nadeln 3 eines Übertragungsrechens 3a der Flachkulierwirkmaschine überlappend zusammengelegt, wobei die Spitzen der jeweiligen Nadeln in die U-förmige Tasche der Gegennadeln eintauchen, so daß ein Überschieben der den Nadelschaft umschließenden Masche von einer Nadel auf die andere möglich wird.The tips of the needles 2 of the push-up rake 2a are overlapped with the tips of the needles 3 of a transfer rake 3a of the flat-knitting machine, the tips of the respective needles dipping into the U-shaped pocket of the opposing needles, so that the stitch surrounding the needle shaft is pushed over by one Needle on the other becomes possible.

Nach Zusammenlegen der Nadeln 2 des Aufstoßrechens 2a und der Nadeln 3 des Übertragungsrechens 3a werden in einer dem Nadelraster entsprechenden Reihe auf einem Träger 4a angeordnete Platinen 4 zwischen die Nadeln 2, 3 gegen den Stapel Rippränder 1 bewegt.After the needles 2 of the pushing rake 2a and the needles 3 of the transfer rake 3a have been folded together, boards 4 arranged on a carrier 4a in a row corresponding to the needle grid are moved between the needles 2, 3 against the stack of rib edges 1.

Die Platinen 4 sind mit Vorlaufkanten 5 und 5a sowie mit einem sich von diesen aus erstreckenden randoffenen Freiraum 6 versehen. An den Platinen 4 befindet sich ferner eine von der Vorlaufkante 5 und der Begrenzungskante des Freiraumes 6 gebildete Stechspitze 7.The boards 4 are provided with leading edges 5 and 5a and with an open space 6 which extends from them and is open at the edge. On the circuit boards 4 there is also a piercing tip 7 formed by the leading edge 5 and the boundary edge of the free space 6.

Mit der Bewegung der Platinen 4 gegen den Stapel Rippränder 1 werden diese von den Vorlaufkanten 5, 5a der Platinen 4 gegen einen hinter dem Stapel Rippränder 1 sich über die gesamte Länge des Aufstoßrechens 2a erstreckenden Anschlag 8 gefahren und zusammengepreßt. Dabei wird der vorderste Ripprand 1 in Längsrichtung ausgerichtet und aufgrund der inneren Elastizität des Ripprandes 1 in dem Freiraum 6 der Platinen 4 eine Welle 1a in der Fläche des Ripprandes 1 gebildet. Durch Vorbewegen der Platinen 4 gegen die Welle 1a dringt nun die Stechspitze 7 in den Wellenrand. (Figur 3a-c)With the movement of the plates 4 against the stack of rib edges 1, these are moved and pressed together by the leading edges 5, 5a of the plates 4 against a stop 8 extending behind the stack of rib edges 1 over the entire length of the opening rake 2a. The foremost rib edge 1 is aligned in the longitudinal direction and, due to the inner elasticity of the rib edge 1 in the free space 6 of the plates 4, a wave 1a is formed in the surface of the rib edge 1. By advancing the plates 4 against the shaft 1a, the piercing tip 7 now penetrates into the shaft edge. (Figure 3a-c)

Die geringe Breite des Freiraumes stellt sicher, daß sich nur der vorderste Ripprand 1 des Stapels in den Freiraum 6 vorwölbt und somit stets ein einzelner Ripprand 1 von den Stechspitzen 7 der Platinen 4 aufgenommen wird.The small width of the free space ensures that only the foremost rib edge 1 of the stack bulges into the free space 6 and thus a single rib edge 1 is always received by the piercing tips 7 of the plates 4.

Nach Einstechen der Stechspitzen 7 ist der Ripprand 1 zwischen diesen und den Nadeln 2 des Aufstoßrechens 2a gespannt und die Platinen 4 bewegen sich vom Stapel des Ripprandes 1 weg und ziehen den ergriffenen Ripprand 1 vom Stapel ab, wobei der Ripprand 1 auf den Nadeln 2 in Richtung der Nadeln 3 des Übertragungsrechens 3a unter Aufrechterhaltung der Spannung gleitet. (Figur 3d)After the piercing tips 7 are inserted, the rib edge 1 is stretched between them and the needles 2 of the opening rake 2a and the sinkers 4 move away from the stack of rib edge 1 and pull the gripped rib edge 1 off the stack, the rib edge 1 on the needles 2 in Direction of the needles 3 of the transfer rake 3a slides while maintaining the tension. (Figure 3d)

Nach einem definierten Abstand zum Stapel der Rippränder 1 bewegen sich die Platinen 4 entgegen ihrer Einstechrichtung aus dem Rand der Rippränder 1 bis ihre Kopfkanten eine Position unter den Aufstoßnadeln 2 erreicht haben. (Figur 3e)After a defined distance from the stack of the rib edges 1, the sinkers 4 move out of the edge of the rib edges 1 against their piercing direction until their head edges have reached a position under the pushing needles 2. (Figure 3e)

Die Platinen 4 fahren nun erneut in Richtung des Stapels der Rippränder 1 bis unter den Spalt zwischen Stapel und separiertem Ripprand 1, um danach mit ihrem Kopfteil in diesen Spalt zu tauchen, und zwar wegen der Funktionssicherheit nur so weit zwischen die Nadeln 2 des Aufstoßrechens 2a, daß die Stechspitzen 7 nicht in den Bereich der Randmaschen des Ripprandes 1 gelangen. (Figur 3f)The boards 4 now travel again in the direction of the stack of the rib edges 1 to below the gap between the stack and the separated rib edge 1, in order to then dip their head part into this gap, because of the functional reliability only so far between the needles 2 of the push-up rake 2a that the piercing tips 7 do not reach the area of the edge stitches of the rib edge 1. (Figure 3f)

Mit dem Rücken der Platinen 4 wird der Ripprand 1 durch eine Bewegung der Platinen 4 in Richtung Übertragungsrechen 3a verschoben, gleitet über die Nadeln 2, 3 hinweg bis zu einer definierten Position auf dem Übertragungs rechen 3a. (Figur 3g)With the back of the sinkers 4, the rib edge 1 is shifted by a movement of the sinkers 4 in the direction of the transfer rake 3a, slides over the needles 2, 3 to a defined position on the transfer rake 3a. (Figure 3g)

Es folgt das Trennen der Aufstoßnadeln 2 von den Übertragungsnadeln 3 und mittels eines Abweiselementes 9, das eine Leiste, ein Stab oder ein mit einer Reihe von Düsen versehenes Rohr sein kann, wird der übergebene Ripprand 1 von den Nadeln 3 des Übertragungsrechens 3a weggeklappt, um ein Verhaken an den Nadeln 3 des Übertragungsrechens 3a zu verhindern. (Figur 3h)This is followed by the separation of the push-on needles 2 from the transfer needles 3 and by means of a deflecting element 9, which can be a bar, a rod or a tube provided with a row of nozzles, the transferred rib edge 1 is folded away from the needles 3 of the transfer rake 3a to prevent snagging on the needles 3 of the transmission rake 3a. (Figure 3h)

Mit abnehmendem Stapel der Rippränder 1 verändern sich zwangsläufig dessen Federungseigenschaften und der letzte Ripprand eines Stapels hätte bei Anlage an einem festen Anschlag kaum einen Federweg. Dies ist jedoch notwendig, um den Ripprand 1 über seine gesamte Länge relativ gleichmäßig den Stechspitzen 7 der Platine 4 anbieten zu können. Die Rippränder 1 haben aufgrund ihres Herstellungsprozeßes leicht verdickte Vertikalkantenbereiche, was bei nicht vorhandenem Federweg dazu führt, daß sich die Platinen 4 über diesen Kantenbereich in den Rand eindrücken, während in der mittleren Zone dieses Eindrücken nicht sichergestellt ist. Um dies zu verhindern, ist der Anschlag 8, an dem sich der Stapel Rippränder 1 abstützt, aus einem elastischen Material gebildet, in das sich die verdickten Kanten des Ripprandes 1 etwas eindrücken.As the stack of rib edges 1 decreases, its springing properties inevitably change, and the last rib edge of a stack would hardly have any spring travel when resting against a fixed stop. However, this is necessary in order to be able to offer the rib edge 1 relatively uniformly to the piercing tips 7 of the circuit board 4 over its entire length. The rib edges 1 have slightly thickened vertical edge areas due to their manufacturing process, which, in the absence of spring travel, leads to the plates 4 pressing into the edge via this edge area, while this pressing is not ensured in the central zone. To prevent this, the stop 8, on which the stack of rib edges 1 is supported, is formed from an elastic material, into which the thickened edges of the rib edge 1 are somewhat pressed.

Figur 4 zeigt einen Übertragungswagen, der über Laufrollen 11 und Bahnen 12 verfahrbar und vor den einzelnen in Reihe angeordneten Strickstellen einer Flachkulierwirkmaschine positionierbar ist. In dem Wagen 10 befindet sich ein Magazin 13 zur Aufnahme der Aufstoßrechen 2a. Das Magazin 13 läßt sich zwischen einer Ausgangsstellung und einer Übergabestellung zum Zusammen führen der Nadeln 2 des Aufstoßrechens 2a und der Nadeln 3 des Übertragungsrechens 3a verschwenken. Vorzugsweise ist das Magazin mit zwei diametral angeordneten Halterungen 14, 15 mit zugehörigen Klemmelementen ausgerüstet, die durch eine Drehbewegung um eine Achse 16 wechselweise zum Einsatz gelangen.FIG. 4 shows a transfer vehicle which can be moved via rollers 11 and tracks 12 and can be positioned in front of the individual knitting points of a flat-knitting machine arranged in a row. In the carriage 10 there is a magazine 13 for receiving the pushing rake 2a. The magazine 13 can between an initial position and a transfer position for guiding together the needles 2 of the opening rake 2a and the needles 3 of the transmission rake 3a. The magazine is preferably equipped with two diametrically arranged brackets 14, 15 with associated clamping elements, which are used alternately by a rotary movement about an axis 16.

Die beiden Hebel 17 und 18 zur Erzeugung der Bewegung der Platinen 5 um Drehpunkte 19 und 20 werden über zwei voneinander unabhängige nicht dargestellte Antriebe betätigt.The two levers 17 and 18 for generating the movement of the plates 5 about pivot points 19 and 20 are actuated by two independent drives, not shown.

Nach Abzug des letzten Ripprandes 1 vom Aufstoßrechen 2a, was über eine Lichtschranke kontrolliert wird, schwenkt ein voller Rechen in Arbeitsposition und in der Parkposition des Wagens 10, die sich außerhalb der Strickstellen befindet, wird der leere Aufstoßrechen vom Maschinenbediener gegen einen mit Ripprändern 1 bestückten neuen Aufstoßrechen 2a ausgetauscht.After deduction of the last rib edge 1 from the opening rake 2a, which is controlled by a light barrier, a full rake swivels in the working position and in the parking position of the carriage 10, which is located outside of the knitting points, the empty opening rake is loaded by the machine operator against one with the rib edges 1 new rake rake 2a replaced.

Die Erfindung beschränkt sich nicht auf das Vereinzeln von auf Aufstoßrechen 2a aufgenadelten Ripprändern 1. Das Verfahren läßt sich auch zum Greifen von beliebigen Textilflächen verwenden. Dabei können die Platinen 4 gegenläufig auf Lücke zusammengefaßt in mehreren Greifmodulen arbeiten.The invention is not limited to the separation of rib edges 1 which have been needled onto push-up rakes 2a. The method can also be used for gripping any textile surface. In this case, the boards 4 can work in opposite directions to form a gap in several gripping modules.

Ferner ist die Erfindung nicht beschränkt auf das dargestellte und beschriebene Ausführungsbeispiel, sie läßt vielmehr zahlreiche Abwandlungen zu. So können die Funktionen Vereinzeln und Überstreifen mit getrennten Elementen ausgeführt werden oder die geometrische Lage der Funktionselemente kann anders gewählt sein.Furthermore, the invention is not limited to the exemplary embodiment shown and described, but rather permits numerous modifications. The functions of separating and slipping on can be carried out with separate elements or the geometric position of the functional elements can be selected differently.
