Description

Die Erfindung bezieht sich auf ein Verfahren zum Erzeugen einer Musterkette, bei dem unterschiedliche Fäden durch rotierende Fadenführer von einem synchron hiermit umlaufenden Drehgatter abgezogen und auf am Umfang einer drehfest gehaltenen Trommel angeordnete achsparallel verlaufende Transportbänder abgelegt werden, sowie auf eine Musterketten-Schärmaschine mit einer drehfest gehaltenen Trommel, an deren Umfang achsparallel verlaufende Transportbänder angeordnet sind, mit einem Drehgatter und mit synchron hiermit drehbaren Fadenführern, die Fäden von Drehgatter abziehen und auf den Transportbändern ablegen.The invention relates to a method for producing a sample chain in which different threads by rotating thread guides from a synchronous hereby revolving rotary gate deducted and on the circumference of a rotationally held drum arranged axially parallel running conveyor belts are stored, as well on a sample chain warping machine with a rotationally fixed held drum, axially parallel on the circumference Conveyor belts are arranged with a Rotary gate and with thread guides that can be rotated synchronously with it, pull the threads from the rotary gate and onto the Put the conveyor belts down.

Dieser Stand der Technik wird durch DE 196 05 924 A1 belegt. Bei der bekannten Musterketten-Schärmaschine trägt das Drehgatter acht Spulen, so daß gleichzeitig acht Fäden mittels der zugehörigen Fadenführer auf dem Trommelumfang abgelegt werden können. Dies erlaubt es, die Zeit zur Herstellung der gewünschten Musterketten kleinzuhalten. Allerdings sind die Musterungsmöglichkeiten beschränkt, weil sich das Muster nach jeweils acht Fäden wiederholt.This state of the art is described in DE 196 05 924 A1 busy. In the well-known warp warping machine the rotary gate carries eight coils, so that at the same time eight threads using the associated thread guides on the Drum circumference can be stored. This allows the time to produce the desired sample chains small injury. However, the pattern options are limited because the pattern changes every time eight threads repeated.

Eine nahezu unbegrenzte Musterungsvielfalt kann man dagegen mit einer auf dem Markt befindlichen Musterketten-Schärmaschine erzielen, bei der immer nur ein Faden von einem Fadenführer aus einem Vorratsmagazin aufgenommen, um die Trommel gewickelt und bei beendetem Bedarf im Vorratsmagazin wieder abgelegt wird. Es folgt dann der nächste Faden, der aus einem anderen Vorratsmagazin aufgenommen, um die Trommel gewickelt und dann wieder abgelegt wird. Hierbei ergeben sich aber längere Produktionszeiten.One can, however, an almost unlimited variety of patterns with a sample warping machine on the market achieve with only one thread at a time picked up by a thread guide from a storage magazine, wrapped around the drum and when needed is stored again in the storage magazine. It follows then the next thread, which comes from another storage magazine recorded, then wrapped around the drum is put down again. This results in longer ones Production times.

Der Erfindung liegt die Aufgabe zugrunde, eine höhere Musterungsvielfalt bei verkürzten Produktionszeiten zu erzielen.The invention has for its object a higher Variety of patterns with shortened production times achieve.

Diese Aufgabe wird verfahrensmäßig durch die Merkmale des Anspruchs 1 gelöst.This task is procedurally determined by the characteristics of claim 1 solved.

Dadurch, daß die nicht benötigten Fäden durch Klemmung mit ihrem Fadenführer verbunden und außerdem zwischen der Klemmstelle und der Trommel abgeschnitten werden, werden die Fäden weiter auf Rotation mitgenommen, nicht aber auf die Trommel aufgewickelt. Damit werden Kollisionen mit den für das Muster benötigten Fäden vermieden. Es kann also eine Auswahl von aus dem Drehgatter zur Verfügung stehenden Fäden gleichzeitig auf die Trommel aufgewickelt werden. Somit lassen sich beliebige Muster in kürzeren Zeiten als bisher erstellen. Soll der zeitweilig nicht benötigte Faden wieder zur Musterung aufgenommen werden, genügt es, daß freie Fadenende stationär festzuhalten und die Klemmung aufzuheben.The fact that the threads not required by clamping connected to their thread guide and also between the clamping point and the drum are cut off, the threads continue to be taken on rotation, not but wound up on the drum. This will make collisions avoided with the threads required for the pattern. So there can be a selection of from the rotary gate available threads simultaneously on the Drum. So any Create patterns in shorter times than before. Should the thread that is temporarily not needed again for patterning it is sufficient that the free end of the thread hold stationary and release the clamp.

Bei der Weiterbildung nach Anspruch 2 ergibt sich eine Musterung, bei der zwei oder mehr gleiche Fäden gleichzeitig gelegt werden können, was bei einer Vielzahl von Mustern eine erhebliche Arbeitserleichterung mit sich bringt.In the development according to claim 2, there is a Pattern in which two or more identical threads are used at the same time what can be laid at a variety of Pattern a significant ease of work with it brings.

Konstruktiv wird die gestellte Aufgabe durch die Merkmale des Anspruchs 3 gelöst. Mit Hilfe der umlaufenden Klemmstellen, der Schneidvorrichtung und der stationären Haltevorrichtung lassen sich die erforderlichen Verfahrensschritte durchführen.The task is constructive through the features of claim 3 solved. With the help of the rotating Clamping points, the cutting device and the stationary Holding device can be the required Perform procedural steps.

Bei der Weiterbildung nach Anspruch 4 ergeben sich Vereinfachungen, weil die einzelnen Schneidstellen zusammen mit den Klemmstellen betätigt werden können.Simplifications result from the further training according to claim 4, because the individual cutting points together can be operated with the clamping points.

Für das Schließen und Öffnen der rotierenden Klemmstellen gibt es verschiedene Möglichkeiten. Besonders empfehlenswert ist die Verwendung eines Malteserkreuzes nach Anspruch 5, weil dies durch eine stationäre Schaltvorrichtung aufgrund der Durchlaufbewegung die zur Betätigung erforderliche Drehung vollführt.For closing and opening the rotating clamping points there are different options. Highly recommended is the use of a Maltese cross according to claim 5, because this is by a stationary Switching device due to the continuous movement rotation required for actuation.

Alternativ kann die Klemmvorrichtung auch gemäß Anspruch 6 mit einem umlaufenden Luftzylinder oder gemäß Anspruch 7 mit einem umlaufenden Elektromagneten betätigt werden, wobei dann die pneumatischen oder elektrischen Signalleitungen über eine Verteilerstelle an der Nabe der Fadenführeranordnung geleitet werden können. Alternatively, the clamping device can also be according to claim 6 with a revolving air cylinder or according to Claim 7 operated with a rotating electromagnet be, then the pneumatic or electrical Signal lines via a distribution point at the Hub of the thread guide assembly can be directed.

Die Musterketten-Schärmaschine der Fig. 1 weist eine Trommel 1 auf, an deren Umfang achsparallele Transportbänder 2, die langsam in Richtung des Pfeiles 3 bewegt werden, und achsparallel Teilstäbe 4, 5 und 6 angeordnet sind, die je nach ihrer Funktion auch als Kreuz-oder Schneidstäbe bezeichnet werden können. Ein Drehgatter 7 weist einen Rotor 8 auf, der eine Mehrzahl von Spulen 9 trägt und durch eine Kardanwelle 17 angetrieben wird. An einem Ende der Trommel 1 befinden sich Fadenführer 11, welche synchron mit dem Rotor 8 des Drehgatters 7 angetrieben werden. Sie ziehen Fäden 12 vom Drehgatter 7 ab und legen sie auf die Transportbänder 2 und wahlweise auf oder unter die Teilstäbe 4, 5 und 6. Die Fäden 12 können alle unterschiedlich sein, bestehen aber vorzugsweise aus mehreren Gruppen 12a und 12b, die jeweils zwei oder mehr gleiche Fäden aufweisen. The pattern warping machine of FIG. 1 has one Drum 1 on the circumference of axially parallel conveyor belts 2, which slowly moves in the direction of arrow 3 are, and axially parallel rods 4, 5 and 6 arranged are, depending on their function, also as cross or Cutting bars can be called. A rotating gate 7 has a rotor 8 which has a plurality of Coils 9 carries and driven by a propeller shaft 17 becomes. Thread guides are located at one end of the drum 1 11, which is synchronous with the rotor 8 of the rotary gate 7 are driven. You pull threads 12 from Rotary gate 7 and place them on the conveyor belts 2 and optionally on or under the partial rods 4, 5 and 6. The threads 12 can all be different, consist but preferably from several groups 12a and 12b, the each have two or more identical threads.

Bei diesem Arbeitsgang ist die Trommel 1 drehfest gehalten, so daß sich eine in Richtung des Pfeiles 3 wandernde Fadenschicht ergibt. In einem zweiten Arbeitsgang werden dann mehrere Fäden gleichzeitig von der sich dabei drehenden Trommel 1 abgezogen, so daß man eine aus einer größeren Zahl von Fäden bestehende Musterkette erhält.In this operation, the drum 1 is held in a rotationally fixed manner, so that a wandering in the direction of arrow 3 Thread layer results. In a second step several threads are then removed from the deducting rotating drum 1, so that one a sample chain consisting of a large number of threads receives.

Fig. 2 zeigt, daß die Fadenführer 11 über einen Arm 13, der den Rand der Trommel 1 übergreift, an radialen Speichen 14 angebracht sind. Die Speichen sind in einer Nabe 15 gehalten, welche durch einen Motor 16 angetrieben ist und - unter Verzicht auf den Motor 10 in Fig. 1 - den Rotor 8 des Drehgatters 7 über eine Kardanwelle 17 mitnimmt. Es sei angenommen, daß sich die beschriebenen Teile im Uhrzeigergegensinn (vergleiche den Pfeil 18) drehen.Fig. 2 shows that the thread guide 11 via an arm 13, which overlaps the edge of the drum 1, on radial Spokes 14 are attached. The spokes are in one Hub 15 held, which is driven by a motor 16 is and - without the motor 10 in Fig. 1 - the rotor 8 of the rotary gate 7 via a propeller shaft 17 takes away. It is assumed that the described Parts clockwise (compare the arrow 18) turn.

Mit jedem Fadenführer 11 ist eine Klemmstelle 19 und eine Schneidstelle 20 verbunden, die in Abhängigkeit von einem vorgegebenen Musterungsprogramm betätigt werden, wenn der betreffende Faden 12 zeitweilig nicht benötigt wird. Wenn der Faden 12 abgeschnitten und festgeklemmt ist, rotiert er mit dem Fadenführer 11 weiter, ohne daß er auf der Trommel 1 abgelegt wird. Um den Faden 12 bei Bedarf wieder zu aktivieren, ist eine stationäre Haltevorrichtung 21 vorgesehen, welche nach Öffnen der Klemmstelle 19 das freie Fadenende 22 festhält, worauf dieser Faden 12 von seinem Fadenführer 11 auf die Trommel 1 aufgewickelt wird. Im vorliegenden Ausführungsbeispiel ist die stationäre Haltevorrichtung 21 durch eine Saugdüse 23 gebildet. Statt dessen oder zusätzlich kann auch eine stationäre Klemmvorrichtung 24 vorgesehen sein. With each thread guide 11 is a nip 19 and a cutting point 20 connected depending are operated by a specified sample program, if the thread in question 12 is temporarily not required becomes. When the thread 12 is cut and clamped he continues to rotate with the thread guide 11, without being placed on drum 1. Around the thread 12 reactivating if necessary is a stationary one Holding device 21 is provided, which after Opening the clamping point 19 holds the free thread end 22, whereupon this thread 12 from its thread guide 11 is wound on the drum 1. In the present The embodiment is the stationary holding device 21 formed by a suction nozzle 23. Instead, or in addition, a stationary clamping device 24 may be provided.

Zur Betätigung der Klemmstelle 19 und der Schneidstelle 20 ist eine Betätigungsvorrichtung 25 vorgesehen, die als Luftzylinder, Elektromagnet, o.dgl. ausgeführt ist und mit den Fadenführern 11 rotiert. Günstiger ist demgegenüber die Verwendung eines Malteserkreuz-Schaltgetriebes 26, dessen Malteserkreuz 27 an der Radialspeiche 14 drehbar gelagert ist. Eine durch einen Luftzylinder 28 betätigbare stationäre Schaltvorrichtung 29 besitzt ein Schaltelement 30, das wahlweise aus der gestrichelt gezeichneten Position in die vollausgezogene Position und damit in Eingriff mit dem Malteserkreuz 27 gebracht werden kann. Während des Vorbeilaufs der radialen Speiche 14 an der Schaltvorrichtung 29 kann daher das Malteserkreuz 27 gedreht werden, wodurch bei einer ersten Drehung um 90° die Klemmstelle 19 geschlossen und die Schneidstelle 20 betätigt wird und bei einer zweiten Drehung um 90° die Klemmstelle 19 wieder geöffnet wird, so daß das freie Fadenende 22 von der Haltevorrichtung 21 ergriffen werden kann.To actuate the clamping point 19 and the cutting point 20 an actuator 25 is provided, the as an air cylinder, electromagnet, or the like. is executed and rotates with the thread guides 11. In contrast, it is cheaper the use of a Maltese cross gearbox 26, whose Maltese cross 27 on the radial spoke 14 is rotatably mounted. One by an air cylinder 28 actuatable stationary switching device 29 has a switching element 30, which is optionally dashed from the drawn position in the fully extended Position and thus in engagement with the Maltese cross 27 can be brought. As the radial passes Spoke 14 on the switching device 29 can therefore the Maltese cross 27 are rotated, whereby at a first rotation of 90 °, the nip 19 closed and the cutting point 20 is actuated and with a second rotation of 90 °, the nip 19 is opened again so that the free thread end 22 of the holding device 21 can be gripped.
