Description

Gegenstand der Erfindung ist ein Verfahren zum Transportieren einer Stoffbahn in einer Stick- oder Steppmaschine gemäss Oberbegriff des Patentanspruches 1.The invention relates to a method for transporting a fabric web in an embroidery or quilting machine according to the preamble of patent claim 1.

Gegenstand der Erfindung ist auch eine Stick-oder Steppmaschine gemäss Oberbegriff der Patentansprüche 4 und 9.The invention also relates to an embroidery or quilting machine according to the preamble of claims 4 and 9.

Stick- und Steppmaschinen sind bekannt.Embroidery and quilting machines are known.

Bei der Steppmaschine nach der Europäischen Patentanmeldung 106810 erfolgt das Spannen und das Zurückführen des Stoffes im Bearbeitungsbereich mit Hilfe eines Walzenpaares, das den Stoff abzugseitig klemmt und einer Spannwalze (Tänzerrolle), die durch einen Zahnstangenantrieb beim Zurückführen des Stoffes den zurückgeführten Stoffabschnitt speichert und gleichzeitig gespannt hält. Mit dieser bekannten Maschine kann der Stoff nicht positionsgetreu vorwärts- und rückwärtstransportiert werden, weil beim Vorwärtstransportieren mit dem abzugsseitigen Walzenpaar die Zugspannung einlaufseitig vom jeweiligen Durchmesser und der Masse der Stoffvorratsrollen sowie von der Trägheit und der Genauigkeit, mit der die Tänzerrolle verschoben wird, abhängig ist; beim Rückführen um einen bestimmten Betrag hingegen wirkt nur die Spannwalze, deren Verschiebung aber unabhängig von den übrigen Parametern, wie Stoffqualität und Dicke, etc., erfolgt. Dadurch ändert sich die Spannung im Stoff innerhalb des Bearbeitungsbereiches, was zu Verschiebungen in den angefertigten Stickmustern führen kann.In the quilting machine according to European patent application 106810, the fabric is tensioned and returned in the processing area with the help of a pair of rollers that clamp the fabric on the take-off side and a tensioning roller (dancer roller) that, by means of a rack and pinion drive, stores the fabric section that is being returned and simultaneously tensioned holds. With this known machine, the fabric cannot be transported forward and backward in the correct position, because when it is transported forward with the pair of draw-off rollers, the tension on the inlet side depends on the respective diameter and the mass of the stock rolls as well as on the inertia and the accuracy with which the dancer roll is moved ; when returning by a certain amount, on the other hand, only the tensioning roller acts, but its displacement is independent of the other parameters, such as fabric quality and thickness, etc. This changes the tension in the fabric within the processing area, which can lead to shifts in the embroidery designs.

Bei der Steppmaschine nach der deutschen offenlegungsschrift 3002340 erfolgt der Vorwärts- und Rückwärtstransport des Stoffes durch einlaufseitig und auslaufseitig angeordnete Walzenpaare.In the quilting machine according to German published patent application 3002340, the fabric is transported forwards and backwards by pairs of rollers arranged on the inlet and outlet sides.

Beim Einziehen des Stoffes wird dessen Spannung durch die jeweilige Trägheit der Stoffvorratsrollen beeinflusst ; beim Rücktransport entfällt diese Spannung vollständig. Durch diese Spannungsunterschiede entstehen auch bei dieser Vorrichtung Fehler im Stepp- oder Stickmuster.When the fabric is drawn in, its tension is influenced by the inertia of the fabric supply rolls; this voltage is completely eliminated during the return transport. These voltage differences also result in errors in the stitching or embroidery pattern in this device.

Die Aufgabe der Erfindung besteht darin, auf der Liefer- und auf der Abzugseite des Bearbeitungsbereiches Verhältnisse zu schaffen, die ein exaktes Bewegen des Stoffes während der Bearbeitung ermöglichen. Insbesondere besteht die Aufgabe darin, die bei Beginn des Stofftransports auf die im Bearbeitungsbereich befindliche Stoffbahn wirkenden Trägheitskräfte auf ein Minimum zu reduzieren und in beiden Transportrichtungen exakt gleiche Verhältnisse zu schaffen.The object of the invention is to create conditions on the delivery side and on the take-off side of the processing area which enable an exact movement of the material during processing. In particular, the task is to reduce the inertial forces acting on the material web located in the processing area at the start of the material transport to a minimum and to create exactly the same conditions in both transport directions.

Eine weitere Aufgabe der Erfindung besteht darin, die im Bearbeitungsbereich angeordnete Nähvorrichtung massearm auszuführen, um ein exaktes, reproduzierbares Stickbild zu erhalten. Nach der Erfindung werden diese Aufgaben gemäss den kennzeichnenden Merkmalen der Patentansprüche 1, 4 und 9 gelöst.Another object of the invention is to design the sewing device arranged in the processing area with low mass in order to obtain an exact, reproducible embroidery image. According to the invention, these objects are achieved according to the characterizing features of claims 1, 4 and 9.

Die spiegelbildliche Anordnung und Ausführung der Walzenpaare und der diesen zugeordneten Tänzerrollen bewirkt während des Vor- und Rückwärtstransportes der Stoffbahn jeweils genau gleiche Verhältnisse, und zwar sowohl bezüglich Materialspannung als auch in Bezug auf die Massenträgheit der im Bearbeitungsbereich auf den Stoff einwirkenden Maschinenteile. Ausserdem werden alle Einflussfaktoren seitens der Stoffvorrats- oder Aufnahmerollen vollständig eliminiert.The mirror-image arrangement and design of the roller pairs and the dancer rollers assigned to them cause exactly the same conditions during the forward and backward transport of the fabric, both with regard to material tension and with respect to the inertia of the machine parts acting on the fabric in the processing area. In addition, all influencing factors on the part of the stock or intake roles are completely eliminated.

Die mit Einzelantrieben versehenen Nähköpfe und Greifervorrichtungen der Nähvorrichtung können mit elektronisch gesteuerten Antrieben mit der vorgegebenen Geschwindigkeit und synchron zueinander quer zur Stoffbahn bewegt und angetrieben werden, ohne dass dazu grosse Massen zu bewegen sind oder seitlich der Maschine ein Ausfahrraum für einen Nähmaschinenträger notwendig ist. Dabei ist es unerheblich, ob mit Doppelsteppstichen oder Kettenstichen genäht wird.The sewing heads and gripper devices of the sewing device, which are provided with individual drives, can be moved and driven with electronically controlled drives at the specified speed and synchronously with one another, transversely to the fabric web, without large masses having to be moved or without an extension space for a sewing machine carrier being necessary to the side of the machine. It is irrelevant whether you use double lockstitch or chain stitch.

In der Figur 1 ist eine Steppmaschine 1 mit einem Rahmen 3, Verbindungsrohren 4, je einem Antriebsmotor 11 für die beiden unter Federkraft aneinander anliegenden, in bekannter Weise zustellbaren Walzenpaare 7, 8 und 9, 10, einem Antriebsmotor 5 für die innenliegenden, ebenfalls in bekannter Weise zustellbaren Walzenpaare 13, 14 und 15, 16 (Figur 2), einem Antriebsmotor 17 zum Verschieben eines Nadelwerkes 19 und des dazugehörigen Greiferwerkes 21 quer zur Steppmaschine 1. Für das Nadelwerk 19 und das Greiferwerk 21 sind Antriebe 23 und 25, z. B. drehzahlgesteuerte Gleichstrommotoren, vorgesehen. Der Antrieb der Walzen 7,8 ; 9, 10 ; 13, 14 ; 15,16 kann kontinuierlich oder schrittweise erfolgen.FIG. 1 shows a quilting machine 1 with a frame 3, connecting tubes 4, one drive motor 11 for each of the two pairs of rollers 7, 8 and 9, 10 that are in contact with each other under spring force and can be adjusted in a known manner, a drive motor 5 for the internal ones, also in Known manner deliverable pairs of rollers 13, 14 and 15, 16 (Figure 2), a drive motor 17 for moving a needle unit 19 and the associated gripper unit 21 transversely to the quilting machine 1. For the needle unit 19 and the gripper unit 21 drives 23 and 25, z. B. speed controlled DC motors provided. The drive of the rollers 7,8; 9, 10; 13, 14; 15, 16 can be continuous or gradual.

Die zu steppenden Stoffbahnen 27 sind in bekannter Weise auf Stoffvorratsrollen 29 vor der Maschine 1 aufgewickelt.The webs of fabric 27 to be quilted are wound in a known manner on fabric supply rolls 29 in front of the machine 1.

Der Antrieb der Walzenpaare 7, 8 ; 9,10 und 13, 14 ; 15, 16 erfolgt formschlüssig mit Zahnriemen oder Ketten. Die Walzenpaare 13, 14 ; 15, 16 werden synchron angetrieben (Figuren 5 und 6).The drive of the roller pairs 7, 8; 9, 10 and 13, 14; 15, 16 takes place in a form-fitting manner with toothed belts or chains. The roller pairs 13, 14; 15, 16 are driven synchronously (Figures 5 and 6).

Zwischen den einlaufseitigen Walzenpaaren 7, 8 und 13, 14 und zwischen den auslaufseitigen Walzenpaaren 9, 10 und 15, 16 sind je eine Tänzerrolle 31 und 33 an Schwenkarmen 35 und 37 frei dreh- und schwenkbar aufgehängt. Die anfänglich einzeln in das einlaufseitige Walzenpaar 7,8 eingeleiteten drei Stoffbahnen 27 werden von dort gemeinsam durch die Maschine 1 geführt. Vom Walzenpaar 7,8 laufen die Stoffbahnen 27 nach unten um die Tänzerrolle 31, von dort nach oben in das Walzenpaar 13, 14. In den Beispielen liegen die Walzen 13, 14 nebeneinander. Selbstverständlich können diese auch übereinander angeordnet sein wie das Walzenpaar 7, 8.Between the inlet-side roller pairs 7, 8 and 13, 14 and between the outlet-side roller pairs 9, 10 and 15, 16, a dancer roller 31 and 33 are suspended on pivot arms 35 and 37 in a freely rotatable and pivotable manner. The three fabric webs 27, which are initially introduced individually into the pair of rollers 7, 8 on the inlet side, are guided together from there through the machine 1. From the pair of rollers 7, 8, the fabric webs 27 run downward around the dancer roll 31, from there upward into the pair of rollers 13, 14. In the examples, the rollers 13, 14 lie side by side. Of course, these can also be arranged one above the other like the pair of rollers 7, 8.

Das Walzenpaar 13,14 begrenzt zusammen mit dem Walzenpaar 15, 16 den Bearbeitungsbereich 39, in welchem die Stoffbahnen 27 miteinander versteppt werden. Wenn es sich um eine Stickmaschine handelt, erfolgt in diesem Bereich das Sticken.The pair of rollers 13, 14, together with the pair of rollers 15, 16, delimit the processing area 39 in which the panels 27 are quilted together. If it is an embroidery machine, embroidery takes place in this area.

Zwischen dem ausgangsseitigen Walzenpaar 15, 16 und dem Walzenpaar 9, 10 wird die Stoffbahn 27 un die Tänzerrolle 33 herumgeführt. Die fertig bearbeitete Stoffbahn 27 verlässt die Maschine 1 nach den Walzen 9, 10 und wird in bekannter, in Figur 3 dargestellter Weise, aufgerollt oder abgelegt.Between the pair of rollers 15, 16 on the output side and the pair of rollers 9, 10, the fabric web 27 is guided around the dancer roller 33. The finished fabric web 27 leaves the machine 1 after the rollers 9, 10 and is rolled up or deposited in a known manner, shown in FIG. 3.

Der Antrieb 23 für das Nadelwerk 19 und der Antrieb 25 für das Greiferwerk 21 sind mit einer Steuerung 41 verbunden, welche den synchronen Lauf der Nadel 43 und des Greifers (nicht sichtbar) steuert und zu Beginn der Arbeit die beiden Werke 19, 21 jeweils in eine Nullposition überführt. Dazu wird die Nadel 43 in die höchste Lage gebracht. Anschliessend wird der Greifer im Greiferwerk 21 synchronisiert. Beim Nähen werden die auf das Nadelwerk 19 und das Greiferwerk 21 durch die Stoffbahn 27, bzw. deren Dicke, Qualität, etc., unterschiedlich einwirkenden Kräfte kontinuierlich überwacht und jede Abweichung vom synchronen Lauf kompensiert.The drive 23 for the needle mechanism 19 and the drive 25 for the gripper mechanism 21 are connected to a controller 41 which controls the synchronous running of the needle 43 and the gripper (not visible) and at the beginning of the work the two mechanisms 19, 21 each in transferred a zero position. For this purpose, the needle 43 is brought into the highest position. The gripper is then synchronized in the gripper mechanism 21. When sewing, the forces acting on the needle mechanism 19 and the gripper mechanism 21 by the fabric web 27, or their thickness, quality, etc., are continuously monitored and any deviation from the synchronous running is compensated.

Die Verschiebung des Nadelwerkes 19 und des Greiferwerkes 21 quer zur Transportrichtung der Stoffbahnen 27 bzw. parallel zu den Klemmstellen in den Walzen 13, 14 ; 15, 16 erfolgt durch synchron vom Antriebsmotor 17 angetriebene Spindeln 45, 47, die in Führungsschienen 49, 51 oberhalb und unterhalb der Bearbeitungsfläche 39 angeordnet sind und das Nadelwerk 19 und das Greiferwerk 21 im wesentlichen spielfrei tragen. Anstelle von Spindeln 45, 47 können zum Verschieben des Nadelwerkes 19 und des Greiferwerkes 21 auch Stahlseile, -bänder oder Ketten verwendet werden (keine Abbildung).The displacement of the needle mechanism 19 and the gripper mechanism 21 transversely to the transport direction of the fabric webs 27 or parallel to the clamping points in the rollers 13, 14; 15, 16 is carried out by spindles 45, 47 driven synchronously by the drive motor 17, which are arranged in guide rails 49, 51 above and below the machining surface 39 and carry the needle mechanism 19 and the gripper mechanism 21 essentially without play. Instead of spindles 45, 47, steel cables, belts or chains can also be used to move the needle mechanism 19 and the gripper mechanism 21 (not shown).

Wie die Antriebe 23, 25 des Nadelwerkes 19 und des Greiferwerkes 21 wird auch der Antriebsmotor 17 für die Spindeln von der Steuerung 41 gesteuert.Like the drives 23, 25 of the needle mechanism 19 and the gripper mechanism 21, the drive motor 17 for the spindles is controlled by the controller 41.

Im folgenden wird die Arbeitsweise der Steppmaschine 1 näher erläutert. Die Stoffbahnen 27 sind, wie bereits oben beschrieben, in die Maschine 1 eingelegt und das fertig bearbeitete Ende an einer leeren Aufnahmerolle 53, die mit einem Antriebsmotor 55 und einer Rutschkupplung 57 verbunden ist, befestigt. Der sich im Bearbeitungsbereich 39 befindliche Abschnitt der Stoffbahn 27 wird von den beiden Walzenpaaren 13, 14 und 15, 16 gespannt gehalten und mit einer von der Steuerung 41 vorgegebenen Geschwindigkeit vorwärtstransportiert. Das Walzenpaar 7, 8 hält die von den Stoffvorratsrollen 29 komnenden Stoffbahnen 27 fest, so dass der in den Bearbeitungsbereich 39 nachgezogene Stoffbahnabschnitt aus der von der Tänzerrolle 31 gebildeten Schlaufe entnommen wird. Der aus dem Bearbeitungsbereich 39 hinaustransportierte Stoffbahnabschnitt vergrössert die Schlaufe zwischen den Walzenpaaren 15, 16 und 9, 10. Die Tänzerrolle 33 hält die Stoffbahn 27 in der Schlaufe gespannt derart, dass bei identischer Masse der Tänzerrollen 31, 33, die Spannung in beiden Schlaufen gleich ist. Dies bewirkt, dass beim Umkehren der Transportrichtung der Stoffbahn 27, d. h. beim Nähen in entgegengesetzter Richtung, gleiche Kräfte auf den zu bearbeitenden, sich im Bearbeitungsbereich 39 befindlichen Stoffbahnabschnitt einwirken. Die durch die Klemmstelle an den Walzenpaaren 13, 14 und 15, 16 hindurch sich teilweise auswirkenden Spannkräfte der Tänzerrollen 31 und 33 sind in beiden Transportrichtungen gleich ; einlaufseitig muss jeweils die Tänzerrolle 31 bzw. 33 beschleunigt werden, auslaufseitig entfällt diese Komponente. Beim kontinuierlichen Betrieb muss selbstverständlich der aus der Schlaufe bei der Tänzerrolle 31 abgezogene Stoff sporadisch ersetzt bzw. der sich in der Schlaufe bei der Tänzerrolle 33 angesanmelte Stoff abgeführt werden. Zu diesem Zweck ist über der Tänzerrolle 31 ein Schalter 59 angeordnet, mit dem der Antrieb der Walzen 7, 8 eingeschaltet und von den Stoffrollen 29 so viel abgewickelt werden kann, bis durch die Tänzerrolle 31 ein weiterer Schalter 61 aktiviert wird, der den Antrieb wieder ausschaltet oder bis durch ein Zeitrelais der Antrieb wieder ausgeschaltet wird. Entsprechende Schalter sind auch bei der Tänzerrolle 33 angebracht, wobei dort die Schaltungen mit umgekehrten Vorzeichen erfolgen, so dass auf der Auslaufseite die Walzen 9, 10 und die Rolle 53 jeweils dann angetrieben werden, wenn die Tänzerrolle 33 an der tiefsten Stelle angelangt ist und die Schlaufe nicht weiter vergrössert werden kann.The operation of the quilting machine 1 is explained in more detail below. As already described above, the fabric webs 27 are inserted into the machine 1 and the finished end is fastened to an empty take-up roll 53, which is connected to a drive motor 55 and a slip clutch 57. The section of the fabric web 27 located in the processing area 39 is held under tension by the two pairs of rollers 13, 14 and 15, 16 and transported forward at a speed predetermined by the controller 41. The pair of rollers 7, 8 hold the fabric webs 27 coming from the fabric supply rollers 29 so that the fabric web section drawn into the processing area 39 is removed from the loop formed by the dancer roller 31. The fabric web section transported out of the processing area 39 enlarges the loop between the roller pairs 15, 16 and 9, 10. The dancer roll 33 holds the fabric web 27 in the loop tensioned in such a way that with identical mass of the dancer rolls 31, 33, the tension in both loops is the same is. This causes that when the transport direction of the fabric web 27 is reversed, i. H. When sewing in the opposite direction, the same forces act on the fabric web section to be processed which is located in the processing area 39. The clamping forces of the dancer rollers 31 and 33, which partially act through the nip on the roller pairs 13, 14 and 15, 16, are the same in both transport directions; the dancer roll 31 or 33 must be accelerated on the inlet side, this component is omitted on the outlet side. In continuous operation, of course, the material drawn from the loop at the dancer roll 31 must be replaced sporadically or the material accumulated in the loop at the dancer roll 33 must be removed. For this purpose, a switch 59 is arranged above the dancer roll 31, with which the drive of the rollers 7, 8 can be switched on and processed by the fabric rolls 29 until a further switch 61 is activated by the dancer roll 31, which activates the drive again switches off or until the drive is switched off again by a time relay. Corresponding switches are also attached to the dancer roller 33, where the switching takes place with the opposite sign, so that the rollers 9, 10 and the roller 53 are driven on the outlet side when the dancer roller 33 has reached the lowest point and the Loop can not be enlarged.

In der Figur 4 sind zwei Steppmaschinen 1 in Serie geschaltet, wobei bei der zweiten Maschine die einlaufseitigen Walzen wegfallen können. Es könnte aber auch eine weitere Tänzerrolle zwischengeschaltet werden, um den Materialvorrat zwischen den beiden Maschinen zu vergrössern.In FIG. 4, two quilting machines 1 are connected in series, the rollers on the inlet side being eliminated in the second machine. Another dancer role could also be interposed in order to increase the material supply between the two machines.

Selbstverständlich können auch Maschinen für unterschiedliche Arbeitsvorgänge hintereinandergeschaltet werden, z. B. eine Maschine für Quernähte und eine für Längsnähte.Of course, machines can also be connected in series for different work processes, e.g. B. a machine for cross seams and one for longitudinal seams.
