Abstract

The embroidery machine, and especially a shuttle embroidery machine, is for the attachment of sequins, pearls, stones and the like, carried on a ribbon. The ribbon is advanced by a peg wheel, with an intermittent drive. The ribbon guide (25) is a swing lever, with a magnet (27) at its free end, to hold the lever in the closed position at a ferromagnetic limit stop (37). When the lever is open, the ribbon can be moved easily into the machine without a shaft (17) rotation. In operation, the ribbon is advanced in steps to bring each sequin opening into position in front of the needle (11) for the needle to penetrate through and the sequin is detached (31) from the ribbon by a beating plate. On a blockage, the swing lever is moved away from the peg wheel.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung für Stickmaschinen, insbesondere Schifflistickmaschinen, zum Ansticken von Pailletten oder dergleichen, die in Form eines Bandes zuführbar sind, mit einem intermittierend antreibbaren Warzenrad zum Vorschub des Bandes, einer das Warzenrad teilweise umgreifenden Führung für das Band und einer Trennvorrichtung, um jeweils eine Paillette vor dem Ansticken vom Band abzutrennen. Die Erfindung betrifft ferner eine Stickmaschine mit einer Vielzahl solcher Vorrichtungen.The present invention relates to a device for embroidery machines, in particular Schifflitickmaschinen, for embroidering sequins or the like, which can be fed in the form of a belt, with an intermittently driven Warzenrad for advancing the tape, the Warzenrad partially encompassing guide for the tape and a separator, to separate one sequin from the band before embroidering. The invention further relates to an embroidery machine with a plurality of such devices.

Vorrichtungen zum Ansticken von Verzierungsmaterialien gibt es schon seit rund hundert Jahren. So beschreibt beispielsweise die DE 174 086 das Aufnähen von sogenannten Flittern oder Schuppen auf Stoffe, wobei der Nadel die Flitter, auch Pailletten genannt, aus einem rohrförmigen Behälter einzeln zugeführt werden. Die Nadel sticht dabei durch ein in jeder Flitter vorgesehenes Loch und befestigt sie so auf den Stoff.Devices for embroidering decorative materials have been around for a hundred years. Thus, for example, DE 174 086 describes the sewing of so-called flakes or scales on fabrics, wherein the needle the baubles, also called sequins, are fed individually from a tubular container. The needle pierces through a hole provided in each bauble and attaches it to the fabric.

In neueren Vorrichtungen wird das Verzierungsmaterial in Form eines Bandes zugeführt. So zeigt die WO 9300468 ein Verfahren und eine Vorrichtung zum Ausführen von Stickereien mit Perlen, bei der ein Perlenband zugeführt und vor dem Ansticken jeweils eine Perle vom Band abgeschnitten wird. Entsprechende Vorrichtungen zum Ansticken von Pailletten oder dergleichen werden durch die US 3,390,650 und US 5,562,057 beschrieben. Bei diesen bekannten Vorrichtungen wird das Band von über den Nadelstösseln angeordneten Bandspulen über ein Förderband, z.B. ein Warzenrad, der Nadel zugeführt. Zum Einführen des Bandes kann eine Führung in Form eines Schwenkhebels oder Blattfeder entgegen der Federkraft vorn verschwenkt werden. Im Betrieb der Vorrichtung steht die Führung mit der Hinterseite des Bandes in Kontakt, d.h. mit derjenigen Seite, die nach dem Ansticken der Paillette auf dem Stoff aufliegt.In newer devices, the decorative material is supplied in the form of a belt. Thus, WO 9300468 shows a method and apparatus for performing bead embroidery in which a beaded tape is fed and one bead is cut from the tape prior to picking. Corresponding devices for embroidering sequins or the like are described by US 3,390,650 and US 5,562,057. In these known devices, the band of tape reels arranged over the needle tappets is fed to the needle via a conveyor belt, for example a warp wheel. To insert the tape, a guide in the form of a pivot lever or leaf spring against the spring force can be pivoted forward. In the operation of the device is the Guide in contact with the back of the band, ie the side that rests on the fabric after embroidering the sequin.

Als Nachteil dieser Vorrichtungen erweist sich der grosse Umschlingungswinkel. Wenn die Teilgenauigkeit, d.h. der Abstand von Paillette zu Paillette ungenau ist, kann das Band nicht richtig erfasst und werden und kann sich verklemmen. Nachteilig ist auch der relativ lange und für eine Inspektion unzulängliche Führungskanal. Dadurch wird die Gefahr, dass das Band geknickt wird, erhöht. Ein langer Kanal verursacht nicht nur eine grössere Reibung, sondern ist auch anfälliger für eine Verstopfung durch Rückstände und Schmutz. Bei einem Verklemmen des Bandes besteht die Gefahr eines Nadelbruchs und einer Beschädigung der Vorrichtung. Als nachteilig hat sich auch das komplizierte Einführen des Paillettenbandes erwiesen. Dieses muss zwischen Warzenrad und Führung eingeführt und dann durch Drehen des Warzenrades zur Trennvorrichtung gefördert werden. Dies erweist sich als besonders umständlich, weil bei einer Stickmaschine eine Vielzahl von Paillettenbändern eingelegt werden muss.The disadvantage of these devices is the large wrap angle. If the part accuracy, i. the distance from sequin to sequin is inaccurate, the band can not be properly grasped and become jammed. Another disadvantage is the relatively long and insufficient for an inspection guide channel. This increases the risk of the belt kinking. A long channel not only causes greater friction but is also more susceptible to clogging by debris and dirt. When jamming the tape there is a risk of needle breakage and damage to the device. A disadvantage has also proved the complicated introduction of the sequin tape. This must be introduced between the worm wheel and guide and then be promoted by turning the paddle wheel to the separator. This proves to be particularly cumbersome, because in an embroidery machine a variety of sequin tapes must be inserted.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung der eingangs erwähnten Gattung zu schaffen, welche das Einführen des Paillettenbandes erleichtert und die Gefahr eines Verklemmens des Paillettenbandes, eines Nadelbruchs und einer Beschädigung der Vorrichtung praktisch ausschliesst.It is therefore an object of the present invention to provide a device of the type mentioned, which facilitates the insertion of the sequin strip and virtually eliminates the risk of jamming of the sequin strip, a needle breakage and damage to the device.

Erfindungsgemäss wird dies dadurch erreicht, dass die Führung von der Vorderseite des Bandes und vom Warzenrad weg beweglich ausgestaltet ist und dass ein Kraftelement vorgesehen ist, welches die Führung im Betrieb der Vorrichtung in Führungslage hält, aber beim Auftreten einer vorbestimmten Gegenkraft unwirksam wird, so dass die Führung vom Warzenrad abgehoben wird. Im Gegensatz zum bekannten Stand der Technik steht bei dieser Vorrichtung die Führung im Betrieb nicht mit der Hinterseite, sondern mit der Vorderseite des Bandes in Kontakt, also der Seite, an welcher beim Ansticken die Nadel in das Loch der jeweiligen Paillette eindringt.According to the invention, this is achieved in that the guide is designed to be movable from the front side of the band and from the warp wheel and that a force element is provided which keeps the guide in a guiding position during operation of the device, but becomes ineffective when a predetermined counterforce occurs, so that the guide is lifted off the worm wheel. In contrast to the known prior art is in this device, the leadership in operation not with the rear side, but with the Front side of the tape in contact, so the side at which the needle penetrates into the hole of the respective sequin when embroidering.

Diese Vorrichtung ermöglicht es, das Band von vorn einzuführen, indem vor dem Einführen des Bandes die Führung vom Warzenrad abgehoben wird. Nach dem Einführen des Bandes wird aber die Führung durch das Kraftelement in der Führungslage gehalten. Sollte sich im Betrieb das Band verklemmen, so wird die Führung vom Band abgehoben, was auch zur Folge hat, dass das Warzenrad das Band nicht mehr fördert. Dadurch wird eine Beschädigung der Vorrichtung und der Nadel verhindert. Ferner kann durch das Abheben der Führung eine Alarmvorrichtung betätigt werden.This device allows the tape to be inserted from the front by lifting the guide from the worm wheel before inserting the tape. After insertion of the tape but the guide is held by the force element in the guiding position. Should the belt jam during operation, the guide will be lifted off the belt, which also results in the warp wheel no longer supporting the belt. This prevents damage to the device and the needle. Furthermore, an alarm device can be actuated by lifting the guide.

Zweckmässigerweise ist ein Anschlag vorgesehen, an welchem die Führung in der Führungslage anschlägt. Dadurch wird verhindert, dass die Führung durch das Kraftelement gegen das Band gedrückt wird.Conveniently, a stop is provided on which the guide strikes in the guide position. This prevents that the guide is pressed by the force element against the tape.

Vorteilhaft ist die Führung als Schwenkhebel ausgebildet. Dies ermöglicht ein bequemes Verschwenken der Führung zum Einführen des Bandes. Vorteilhaft ist der Schwenkhebel unterhalb des Warzenrades verschwenkbar gelagert. Dies ermöglicht eine einfache Konstruktion und der Umschlingungswinkel kann klein gehalten werden. Als Kraftelement kann ein Magnet dienen. Die Verwendung eines Magneten hat den Vorteil, dass die Führung nur in der Führungslage mit einer relativ grossen Kraft festgehalten wird. Bei einem Verklemmen des Bandes wird daher die Führung vom Warzenrad abgehoben und verbleibt in der abgehobenen Lage. Zweckmässigerweise ist der Magnet durch eine Schraube verstellbar am freien Ende des Schwenkhebels angeordnet. Durch Verdrehen der Schraube kann der Spalt zwischen dem Warzenrad und der Führung eingestellt werden.Advantageously, the guide is designed as a pivot lever. This allows a comfortable pivoting of the guide for inserting the tape. Advantageously, the pivot lever is pivotally mounted below the Warzenrades. This allows a simple construction and the wrap angle can be kept small. As a force element can serve a magnet. The use of a magnet has the advantage that the guide is held only in the guide position with a relatively large force. In a jamming of the tape, therefore, the guide is lifted from the warp wheel and remains in the off-hook position. Conveniently, the magnet is arranged by a screw adjustable at the free end of the pivot lever. By turning the screw, the gap between the Warzenrad and the guide can be adjusted.

Zweckmässigerweise wird eine stationäre Führung in Förderrichtung des Bandes dem Warzenrad nachgeschaltet, um das Band der Trennvorrichtung zuzuführen.Conveniently, a stationary guide in the conveying direction of the belt is followed by the cam follower in order to feed the belt to the separating device.

Die Erfindung betrifft auch eine Stickmaschine mit einer Vielzahl von Vorrichtungen der beschriebenen Art, wobei die Warzenräder auf einer gemeinsamen Welle angeordnet sind, welche an ein von der Maschinensteuerung steuerbares Antriebsorgan, zum Beispiel einen Servomotor, gekoppelt ist. Dabei ist es vorteilhaft, den Antrieb der Welle in der Mitte vorzunehmen, so dass die Torsion der Welle klein gehalten werden kann.The invention also relates to an embroidery machine with a plurality of devices of the type described, wherein the cam followers are arranged on a common shaft, which is coupled to a controllable by the machine control drive member, for example a servo motor. It is advantageous to make the drive of the shaft in the middle, so that the torsion of the shaft can be kept small.

Es gibt verschiedene Möglichkeiten, die Trennvorrichtung zu gestalten. Vorteilhaft weist die Trennvorrichtung eine stationäre Abschlagkante und eine bewegliche Schlagplatte auf, wobei die bewegliche Schlagplatte durch den Nadelstössel betätigbar ist. Die Schlagplatte kann auch am Nadelstössel angeordnet sein. Dies ergibt eine besonders einfache und kostengünstige Konstruktion.There are several ways to design the separator. Advantageously, the separating device has a stationary knock-off edge and a movable striking plate, wherein the movable striking plate can be actuated by the needle plunger. The striking plate can also be arranged on the needle plunger. This results in a particularly simple and inexpensive construction.

Wie die Figuren 1 und 2 zeigen, sind auf einer Stickmaschine, welche eine Vielzahl von Stickstellen mit Nadeln 11 aufweist, eine Anzahl von Vorrichtungen 12 zum Ansticken von Pailletten 13 mit Löchern 16 angeordnet. Die Pailletten 13 werden von Spulen 14 in Form von Bändern 15 den Nadeln 11 zum Ansticken zugeführt. Die Vorrichtungen 12 zum Ansticken der Pailletten besitzen eine gemeinsame Antriebswelle 17 für die Warzenräder 19. Der Antrieb der Antriebswelle 17 erfolgt durch einen Servomotor 21 über ein Zahnriemengetriebe 23.As shown in FIGS. 1 and 2, a number of devices 12 for embroidering sequins 13 with holes 16 are arranged on an embroidery machine having a multiplicity of needles 11. The sequins 13 are fed by spools 14 in the form of ribbons 15 to the needles 11 for embroidering. The devices 12 for embroidering the sequins have a common drive shaft 17 for the Warzenräder 19. The drive of the drive shaft 17 is effected by a servo motor 21 via a toothed belt transmission 23rd

Wie die Figuren 2 bis 6 zeigen, besteht die Vorrichtung 12 zum Ansticken von Pailletten im wesentlichen aus dem Warzenrad 19 zum Vorschub des Bandes 15, einer das Warzenrad 19 teilweise umgreifenden beweglichen Führung 25, einem Kraftelement 27, welches die Führung 25 im Betrieb der Vorrichtung in der in Figur 4 gezeigten Führungslage hält, und einer Trennvorrichtung 31 (Fig. 5).As shown in Figures 2 to 6, the device 12 for embroidering sequins consists essentially of the Warzenrad 19 for advancing the belt 15, a Warzenrad 19 partially encompassing movable guide 25, a force element 27, which the guide 25 during operation of the device in the guiding position shown in FIG. 4, and a separating device 31 (FIG. 5).

Wie aus den Figuren 3 und 4 ersichtlich ist, wird bei diesem Ausführungsbeispiel das jeweilige Warzenrad 19 durch die Hohlwelle 17 gebildet, in welcher Stifte 33 eingelassen sind, welche die Warzen 33 bilden.As can be seen from FIGS. 3 and 4, in this exemplary embodiment the respective cam wheel 19 is formed by the hollow shaft 17, in which pins 33 are embedded, which form the warts 33.

Die bewegliche Führung 25 ist als Schwenkhebel ausgebildet, welcher mittels eines Stifts 35 unterhalb des Warzenrads 19 verschwenkbar gelagert ist. Eine Stange 37 aus ferromagnetischem Material dient als Anschlag für den Schwenkhebel 25 in der in Figur 4 gezeigten Führungslage.The movable guide 25 is designed as a pivot lever which is pivotably mounted by means of a pin 35 below the cam wheel 19. A rod 37 made of ferromagnetic material serves as a stop for the pivot lever 25 in the guide position shown in FIG.

Als Kraftelement 27 kann ein Magnet dienen, der mittels einer Schraube 39 am freien Ende des Schwenkhebels 25 verstellbar angeordnet ist. Es wäre aber auch möglich, den Magneten 27 an der Stange 37 anzuordnen, in welchem Fall die Führung 25 aus ferromagnetischem Material besteht.As a force element 27 may serve a magnet which is arranged adjustable by means of a screw 39 at the free end of the pivot lever 25. But it would also be possible to arrange the magnet 27 on the rod 37, in which case the guide 25 is made of ferromagnetic material.

Dem Warzenrad 19 ist in Förderrichtung des Bandes 15 eine stationäre Führung 41 nachgeschaltet, um das Band 15 der Nadel 11 bzw. der Trennvorrichtung 31 zuzuführen.The warp wheel 19 is followed by a stationary guide 41 in the conveying direction of the belt 15 in order to feed the belt 15 to the needle 11 or the separating device 31.

Wie Fig. 5 zeigt, besteht die Trennvorrichtung 31 beispielsweise aus der stationären Abschlagkante 43 und der beweglichen Schlagplatte 45, die am Nadelstössel 47 angeordnet ist.As shown in FIG. 5, the separating device 31 consists for example of the stationary knock-off edge 43 and the movable striking plate 45, which is arranged on the needle tappet 47.

Es ist aus Fig. 3 ersichtlich, dass bei der beschriebenen Vorrichtung das Paillettenband 15 mit Leichtigkeit von vom eingeführt werden kann, wenn sich der Schwenkhebel 25 in der geöffneten Lage befindet. Beim Schliessen des Schwenkhebels 25 liegt dieser an der Vorderseite des Paillettenbandes 15 an, also an der Seite, an welcher die Nadel 11 beim Ansticken in das Loch 16 der Paillette 13 eindringt.It can be seen from Fig. 3 that in the described device, the sequin belt 15 can be inserted with ease from of when the pivot lever 25 is in the open position. When closing the pivot lever 25, this is applied to the front of the sequin strip 15, ie on the side at which the needle 11 penetrates when picking in the hole 16 of the sequin 13.

Im Betrieb der Stickmaschine werden die Paillettenbänder 15 gesteuert von der Steuerung der Stickmaschine intermittierend vom Servomotor 21, der die Antriebswelle 17 antreibt, vorgeschoben, so dass jeweils eine Paillette 13 über die Abschlagkante 43 hinaus in die Stellung vorgeschoben wird, in welche die Nadel 11 in das Loch 16 eindringen kann. Die Paillette 13 wird dann bei der weiteren Bewegung des Nadelstössels 47 durch die Schlagplatte 45 abgetrennt. Durch Stiche der Nadel 11 ausserhalb der Peripherie der Paillette wird diese auf dem Stoff weiter befestigt, worauf die nächste Paillette in gleicher Weise vorgeschoben, abgetrennt und befestigt wird, usw..In operation of the embroidery machine, the sequin belts 15 are fed intermittently under the control of the embroidery machine by the servo motor 21 which drives the drive shaft 17, so that a sequin 13 is fed beyond the tee edge 43 into the position in which the needle 11 in the hole 16 can penetrate.
