Description

Die vorliegende Erfindung betrifft ein Verfahren zur Stichbildung einer Schifflistickmaschine, bei welchem der Vorderfaden beim Abziehen von der Spule eine Fadenwalze antreibt.The present invention relates to a method for stitch formation in a ship embroidery machine, in which the front thread drives a thread roller when it is pulled off the bobbin.

Im Werk von Schöner, Spitzen, Enzyklopädie der Spitzentechniken, VEB Fachbuchverlag Leipzig 1980, Seiten 320 bis 325 wird der Stichbildungsvorgang, wie er bei einer Schifflistickmaschine zur Anwendung gelangt, beschrieben. In Figur 1, welche dem zitierten Werk entnommen ist, wird der Stichbildungsvorgang in sechs Phasen a) bis f) dargestellt.In the work of Schönes, Spitzen, Encyclopedia of Lace Techniques, VEB Fachbuchverlag Leipzig 1980, pages 320 to 325, the stitch formation process as used in a Schifflistickmaschine is described. In Figure 1, which is taken from the cited work, the stitch formation process is shown in six phases a) to f).

Der Vorderfaden 11, auch Nadelfaden genannt, führt von der Fadenspule 12 über die Fadenwalze 13 zum kleinen Fadenleiter 14 und von dort über den grossen Fadenleiter 15 zur Nadel 16. Der Hinterfaden 21, der von der Bobine 22 im Schiffchen 23 geliefert wird, wird bei der Stichbildung durch eine Schlaufe 24 des Vorderfadens 11 hindurchgeführt (Phase c) und d)) und vom Vorderfaden 11 festgezogen (Phase e)).The front thread 11, also called the needle thread, leads from the thread spool 12 via the thread roller 13 to the small thread guide 14 and from there via the large thread guide 15 to the needle 16. The rear thread 21, which is supplied by the bobbin 22 in the shuttle 23, is at the stitch formation through a loop 24 of the front thread 11 passed (phase c) and d)) and tightened by the front thread 11 (phase e)).

In der Phase a) bewegt sich das Gatter (nicht dargestellt) mit dem Stickboden 18 und zieht den Faden entsprechend der Stichlänge von der Fadenspule 12 ab. Der kleine Fadenleiter 14 beginnt seinen Ausschlag in Richtung zum Stickboden 18 hin und zieht dabei weiter Faden von der Spule 12 ab (Phase b)). Da der Faden um die Fadenwalze 13 geschlungen ist, wird diese beim Abziehen des Fadens in Bewegung gesetzt.In phase a) the creel (not shown) moves with the embroidery base 18 and pulls the thread from the thread spool 12 according to the stitch length. The small thread conductor 14 begins its deflection in the direction of the embroidery base 18 and continues to pull thread from the spool 12 (phase b)). Since the thread is wrapped around the thread roller 13, it is set in motion when the thread is pulled off.

In den letzten Jahren ist die Geschwindigkeit, mit welcher Schifflistickmaschinen arbeiten, ständig gesteigert worden. Moderne Schifflistickmaschinen arbeiten nun mit mehr als zweihundert Stichen pro Minute. Mit den erhöhten Stickgeschwindigkeiten ist jedoch auch die Tendenz zu Fadenbrüchen gestiegen.In recent years, the speed at which Schiffli embroidery machines work has increased steadily. Modern ship embroidery machines now work with more than two hundred stitches per minute. However, with the increased embroidery speeds, the tendency for thread breaks has increased.

Es ist Aufgabe der vorliegenden Erfindung, ein rasches Arbeiten von Schifflistickmaschinen zu ermöglichen, ohne dass es dabei zu vermehrten Fadenbrüchen kommt.It is an object of the present invention to enable Schiffli embroidery machines to work quickly without increasing thread breaks.

Ein Verfahren zur Stichbildung bei einer Schifflistickmaschine, bei welcher der Vorderfaden beim Abziehen von der Spule eine Fadenwalze antreibt ist erfindungsgemäss dadurch gekennzeichnet, dass beim Abziehen des Vorderfadens die Bewegung der Fadenwalze durch eine Antriebsvorrichtung unterstützt wird. Es hat sich gezeigt, dass durch eine solche Anfahrtshilfe für die Fadenwalze die Tendenz zu Fadenbrüchen auch bei schnellaufender Maschine stark gesenkt wird. Dies erlaubt es, auch Garne mit relativ geringer Reissfestigkeit mit grosser Geschwindigkeit zu verarbeiten.A method for stitch formation in a Schiffli embroidery machine, in which the front thread drives a thread roller when it is pulled off the bobbin, is characterized in that the movement of the thread roller is supported by a drive device when the front thread is removed. It has been shown that such a start-up aid for the thread roller significantly reduces the tendency for thread breaks even when the machine is running at high speed. This allows yarns with a relatively low tensile strength to be processed at high speed.

Eine zweckmässige Ausbildung des Verfahrens sieht vor, dass das durch die Antriebsvorrichtung auf die Fadenwalze ausgeübte Drehmoment entsprechend den Bedürfnissen der Stichbildung eingestellt wird.An expedient embodiment of the method provides that the torque exerted on the thread roller by the drive device is adjusted according to the needs of stitch formation.

Die Erfindung betrifft auch eine Vorrichtung zur Stichbildung bei einer Schifflistickmaschine, bei welcher der Vorderfaden über die Fadenwalze zur Nadel verläuft und beim Abziehen des Vorderfadens von der Spule für den Antrieb der Fadenwalze sorgt und dadurch gekennzeichnet ist, dass zusätzlich eine Antriebsvorrichtung zur Unterstützung des Antriebs der Fadenwalze vorgesehen ist. Zweckmässigerweise ist die Antriebsvorrichtung über eine Kupplung mit der Fadenwalze kuppelbar. Dabei ist es zweckmässig, wenn die Kupplung eine Einstellung des zu übertragenden Drehmoments erlaubt. Ein vorteilhaftes Ausführungsbeispiel der Erfindung sieht daher vor, dass die Kupplung ein Differenzialgetriebe mit einem ersten und einem zweiten Sonnenrad und einem Planetenrad aufweist, wobei der Antriebsstrang von der Antriebsvorrichtung zur Fadenwalze über das erste Sonnenrad, das Planetenrad zum zweiten Sonnenrad verläuft, dass das Planetenrad drehbar auf einer um eine Achse drehbare Scheibe angeordnet ist und dass eine Bremsvorrichtung vorgesehen ist, mit welcher eine Bremskraft auf die drehbare Scheibe ausgeübt werden kann. Dies erlaubt es, durch Betätigung der Bremsvorrichtung, ein Drehmoment auf die Fadenwalze zu übertragen. Vorteilhaft weist die Bremsvorrichtung Mittel zur Regelung der Bremskraft auf. Dies erlaubt es durch Einstellung der Bremskraft das Drehmoment, welches auf die Fadenwalze übertragen wird, zu regulieren.The invention also relates to a device for stitch formation in a Schifflistickmaschine, in which the front thread runs over the thread roller to the needle and provides for driving the thread roller when the front thread is pulled from the bobbin and is characterized in that in addition a drive device for supporting the drive of the Thread roller is provided. The drive device can expediently be coupled to the thread roller via a clutch. It is useful if the clutch allows adjustment of the torque to be transmitted. An advantageous embodiment of the invention therefore provides that the clutch has a differential gear with a first and a second sun gear and a planet gear, the drive train running from the drive device to the thread roller via the first sun gear, the planet gear to the second sun gear, so that the planet gear rotates is arranged on a disc rotatable about an axis and that a braking device is provided with which a braking force can be exerted on the rotatable disc. This allows torque to be transmitted to the thread roller by actuating the braking device. The braking device advantageously has means for regulating the braking force. This allows the torque that is transferred to the thread roller to be regulated by adjusting the braking force.

Die in den Figuren 2 und 3 dargestellte Vorrichtung besteht im wesentlichen aus der Antriebsvorrichtung 25 und der Kupplung 27. Mittels der Kupplung 27 kann die Welle 29 über eine Freilaufnabe 28 in einer Richtung angetrieben werden. Von der Welle 29 erfolgt die Kraftübertragung über die Kegelräder 30,31 auf die Antriebswelle 33 der Fadenwalze 13. Beim dargestellten Ausführungsbeispiel umfasst die Antriebsvorrichtung 25 einen Motor 35, z.B. einen Schrittschaltmotor, welcher über die kleine Riemenscheibe 37 und den Zahnriemen 39 die grosse Riemenscheibe 41 antreibt. Die grosse Riemenscheibe 41 ist mittels der Bolzen 43 mit dem Zahnrad 45 verbunden. Das Zahnrad 45 stellt das erste Sonnenrad eines Differenzialgetriebes dar. Das Planetenrad 47 besteht aus zwei Zahnrädern 48,49, die fest miteinander verbunden sind. Das Zahnrad 48 ist mit dem ersten Sonnenrad 45 und das Zahnrad 49 mit dem zweiten Sonnenrad 51 im Eingriff, welches über die Freilaufnabe 28 die Welle 29 antreiben kann.The device shown in FIGS. 2 and 3 essentially consists of the drive device 25 and the clutch 27. By means of the clutch 27, the shaft 29 can be driven in one direction via a freewheel hub 28. Power is transmitted from the shaft 29 via the bevel gears 30, 31 to the drive shaft 33 of the thread roller 13. In the exemplary embodiment shown, the drive device 25 comprises a motor 35, for example a stepping motor, which, via the small pulley 37 and the toothed belt 39, the large pulley 41 drives. The large pulley 41 is connected to the gear 45 by means of the bolts 43. The gear 45 represents the first sun gear of a differential gear. The planet gear 47 consists of two gear wheels 48, 49, which are firmly connected to one another. The gear 48 is in engagement with the first sun gear 45 and the gear 49 with the second sun gear 51, which can drive the shaft 29 via the freewheel hub 28.

Der Antriebsstrang von der Antriebsvorrichtung 25 verläuft also über die Riemenscheibe 37, den Zahnriemen 39, die Riemenscheibe 41, das erste Sonnenrad 45, das Planetenrad 47, das zweite Sonnenrad 51, die Freilaufnabe 28, die Welle 29, die Kegelräder 30,31 und die Antriebswelle 33 zur Fadenwalze 13.The drive train from the drive device 25 thus runs over the pulley 37, the toothed belt 39, the pulley 41, the first sun gear 45, the planet gear 47, the second sun gear 51, the freewheel hub 28, the shaft 29, the bevel gears 30, 31 and Drive shaft 33 to thread roller 13.

Die Antriebsvorrichtung 25, die Kupplung 27 mit der Bremsvorrichtung 53 sind auf einer Support-Platte 54 gelagert. Wie Figur 2 zeigt, befindet sich in der Support-Platte 54 eine Büchse 55. Die Welle 29 ist in dieser Büchse mittels der beiden Kugellager 56,57 drehbar gelagert. Die Riemenscheibe 41 ist auf der Büchse 55 mittels der Kugellager 59,60 drehbar gelagert. Auf der Nabe 61 der Riemenscheibe ist mittels der Kugellager 63,64 eine Scheibe 65 drehbar gelagert, welche die Bremsscheibe der Bremsvorrichtung 53 darstellt und zugleich das Planetenrad 47 trägt, welches sich um die Achse 67 drehen kann, welche mit dem Schraubenbolzen 69 auf der Scheibe 65 befestigt ist. Auf die Peripherie der Bremsscheibe 65 kann die Bremsbacke 52 der Bremse 53 einwirken. Mit der Stellschraube 71 kann die Feder 73 mehr oder weniger stark vorgespannt und so der Druck der Bremsbacke 52 auf die Bremsscheibe 65 verstellt werden.The drive device 25, the clutch 27 with the brake device 53 are mounted on a support plate 54. As FIG. 2 shows, there is a bush 55 in the support plate 54. The shaft 29 is rotatably mounted in this bush by means of the two ball bearings 56, 57. The pulley 41 is rotatably supported on the bush 55 by means of the ball bearings 59, 60. On the hub 61 of the pulley, a disk 65 is rotatably supported by means of the ball bearings 63, 64, which represents the brake disk of the braking device 53 and at the same time carries the planet gear 47, which can rotate about the axis 67, which is located on the disk with the screw bolt 69 65 is attached. The brake shoe 52 of the brake 53 can act on the periphery of the brake disk 65. With the adjusting screw 71, the spring 73 can be biased to a greater or lesser extent and the pressure of the brake shoe 52 on the brake disk 65 can thus be adjusted.

Die Vorrichtung arbeitet wie folgt:The device works as follows:

Sobald beim Stickvorgang Faden von der Spule 12 abgezogen werden muss, treibt die Antriebsvorrichtung 35 über den Zahnriemen 39, die Kupplung 27 und das Winkelgetriebe 30,31 die Antriebswelle 33 der Fadenwalze 13 an. Das auf die Fadenwalze ausgeübte Drehmoment kann mit der Bremse 53 eingestellt werden. Zu diesem Zweck wird mit der Stellschraube 71 die Feder 73 mehr oder weniger stark eingestellt. Die Freilaufnabe 28 ermöglicht auch eine Weiterbewegung der Fadenwalze 13 durch den Fadenzug, wenn von der Antriebsvorrichtung 35 kein Drehmoment mehr auf die Fadenwalze übertragen wird.As soon as thread has to be withdrawn from the bobbin 12 during the embroidery process, the drive device 35 drives the drive shaft 33 of the thread roller 13 via the toothed belt 39, the coupling 27 and the angular gear 30, 31. The torque exerted on the thread roller can be adjusted with the brake 53. For this purpose, the spring 73 is more or less adjusted with the adjusting screw 71. The freewheel hub 28 also allows the thread roller 13 to move further through the thread pull when the drive device 35 no longer transmits torque to the thread roller.

Es sind verschiedene Aenderungen möglich, ohne vom Erfindungsgedanken abzuweichen. So könnte beispielsweise der Antrieb statt durch einen Motor 35 auch durch die Hauptantriebswelle erfolgen. Dazu kann ein Schrittschaltgetriebe, z.B. ein Maltesergetriebe dienen.Various changes are possible without deviating from the inventive concept. For example, the Drive instead of a motor 35 also take place through the main drive shaft. A stepper transmission, for example a Geneva transmission, can be used for this.
