Description

Die vorliegende Erfindung betrifft ein Gatter gemäss Oberbegriff des Patentanspruches 1.The present invention relates to a gate according to the preamble of claim 1.

Gatter der genannten Gattung sind bekannt und bestehen aus zwei die Enden eines streifenförmigen Stickereigrundes aufnehmenden Stoffwellen, welche mit Rätschenkupplungen versehen sind, die beim Spannen des Stikkereigrundes ein Zurückdrehen der Wellen verhindern. (Zum Beispiel US-A-3 183 866). Bei diesen Vorrichtungen wird der zu bestickende Bereich des Stickgrundes vor die Sticknadeln geführt und anschliessend werden die beiden Stoffwellen soweit gedreht, bis der Stickereigrund die gewünschte Spannung aufweist. Beim Spannen kann aber nicht verhindert werden, dass sich der zu bestickende Bereich verschiebt. Vom Bedienungspersonal wird deshalb sehr viel Geschicklichkeit bei dieser sich nach jedem Stichdurchgang wiederholenden Arbeit verlangt.Gates of the type mentioned are known and consist of two fabric shafts receiving the ends of a strip-shaped embroidery base, which are provided with ratchet couplings which prevent the shafts from turning back when the embroidery base is stretched. (For example, US-A-3 183 866). In these devices, the area of the embroidery base to be embroidered is guided in front of the embroidery needles and the two fabric shafts are then rotated until the embroidery base has the desired tension. When tensioning, however, the area to be embroidered cannot be prevented from shifting. A great deal of skill is therefore required from the operating personnel in this work, which is repeated after each stitch pass.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Vorrichtung zu schaffen, mit welcher der Stickgrund gleichmässig gespannt werden kann und dies unabhängig von der Teilung des Klinkenrades an der Stoffwelle.The object of the present invention is therefore to provide a device with which the embroidery base can be stretched uniformly, regardless of the pitch of the ratchet wheel on the fabric shaft.

Diese Aufgabe wird nach der Erfindung gemäss den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausführungsformen sind in den abhängigen Ansprüchen beschrieben.This object is achieved according to the invention according to the characterizing features of patent claim 1. Further advantageous embodiments are described in the dependent claims.

Durch die Verwendung eines an beiden Stoffwellen gleichzeitig angreifenden Zugmittels mit einem vom Gatter unabhängig gelagerten Antrieb kann der Stickereigrund auch in gespanntem Zustand verschoben werden, d.h. entweder von der oberen auf die untere oder von der unteren auf die obere Stoffwelle gewickelt werden. Bei bereits vor dem Spannen in den Stickereigrund eingesteckten Nadeln, bzw. beim Nachspannen ermöglicht der frei verschiebbare Antrieb eine absolut gleichmässige Verteilung der Spannkräfte beidseitig der Nadeln.By using a traction device that acts on both material shafts at the same time and has a drive that is mounted independently of the creel, the embroidery base can also be moved in a tensioned state, i.e. either from the top to the bottom or from the bottom to the top fabric shaft. When the needles are inserted into the embroidery base before tensioning or when tensioning, the freely displaceable drive enables an absolutely even distribution of the tension forces on both sides of the needles.

Sehr vorteilhaft wirkt sich die Trennung der Stoffwellen von den Antriebsscheiben mittels einer Klinkenkupplung aus, weil dadurch die Stoffwellen bei entspanntem Stickereigrund frei drehbar sind.The separation of the material shafts from the drive pulleys by means of a ratchet coupling has a very advantageous effect because the material shafts can be freely rotated while the embroidery is relaxed.

Beim Verkürzen der Zugmittel, d.h. beim Spannen derselben rasten die Klinken an den vom Zugmittel umschlungenen Scheiben sofort an den Verzahnungen an den Stoffwellen ein und zwar unabhängig von deren momentanen Stellung.When shortening the traction means, i.e. When the same is tensioned, the pawls on the disks wrapped in the traction means snap into place on the toothing on the material shafts, regardless of their current position.

Anhand eines illustrierten Ausführungsbeispieles wird die Erfindung näher beschrieben. Es zeigen:

  • Figur 1 eine Ansicht eines Gatters für eine Schiffchenstickmaschine,
  • Figur 2 einen Schnitt längs Linie 11-11 in Figur 1 mit ungespanntem Stickereigrund,
  • Figur 3 einen Schnitt längs Linie II-II in Figur 1 mit gespanntem Stickereigrund.
The invention is described in more detail using an illustrated embodiment. Show it:
  • FIG. 1 shows a view of a gate for a shuttle embroidery machine,
  • FIG. 2 shows a section along line 11-11 in FIG. 1 with the embroidery base unstressed,
  • 3 shows a section along line II-II in FIG. 1 with the embroidery base stretched.

An einem aus zwei Säulen 1 und einer Querstrebe 2 bestehenden herkömmlichen Gatterrahmen 3 sind oben und unten je eine Stoffwelle 5 drehbar gelagert. Um die beiden Stoffwellen 5 ist der Stickereigrund oder -stoff 6 gelegt, wobei auf die untere Stoffwelle 5 der bestickte Stoff 6 aufgewickelt und von der oberen Stoffwelle 5 der zu bestickende Stoff 6 abgewickelt wird. Die strichpunktierte Linie A bezeichnet die Ebene, in der die Nadeln einer Stickmaschine (nicht dargestellt) zu liegen kommen. Auf dem rechtsliegenden Ende der Stoffwellen 5 sind je eine Antriebsscheibe 8 zur Aufnahme eines um diese gewickelten Drahtseiles oder eines Stahlbandes 9 koaxial aufgesetzt. Die beiden Seile oder Bänder 9 sind durch ein Spannaggregat, z. B. einem mit einer Spindel 11 versehenen Antriebsmotor 12 und einer auf der Spindel 11 aufgesetzten Spindelmutter 14 verbunden.On a conventional gate frame 3 consisting of two columns 1 and a cross strut 2, a fabric shaft 5 is rotatably supported at the top and bottom. The embroidery base or fabric 6 is placed around the two fabric shafts 5, the embroidered fabric 6 being wound onto the lower fabric shaft 5 and the fabric 6 to be embroidered being unwound from the upper fabric shaft 5. The dash-dotted line A denotes the plane in which the needles of an embroidery machine (not shown) come to rest. On the right-hand end of the fabric shafts 5, a drive pulley 8 for receiving a wire rope or a steel band 9 wound around it is placed coaxially. The two ropes or straps 9 are by a tensioning unit, for. B. connected to a spindle 11 drive motor 12 and a spindle nut 14 placed on the spindle 11.

In den Querschnitten nach den Figuren 2 und 3 ist die Säule 1 ebenfalls sichtbar. Davor liegen die Scheiben 8 mit den diese peripher umschlingenden Drahtseilen 9 sowie dem Stoff 6 auf den Stoffwellen 5.Column 1 is also visible in the cross sections according to FIGS. 2 and 3. In front of this, the disks 8 with the wire ropes 9 which surround them peripherally and the material 6 lie on the material waves 5.

Die Stoffwellen 5 weisen stirnseitig eine Verzahnung 13 in Gestalt eines Zahnkranzes auf, in den eine an der Scheibe 8 schwenkbar befestigte Klinke 15 eingreifen kann. In Figur 2 ist das rückwärtige Ende 19 der Klinke 15 ausser Kontakt mit einer am Drahtseil 9 befestigten Platte 21, wenn diese und damit auch der Stoff 6 gespannt sind.The material shafts 5 have a toothing 13 in the form of a toothed ring in the end, into which a pawl 15 pivotably attached to the disk 8 can engage. In Figure 2, the rear end 19 of the pawl 15 is out of contact with a plate 21 attached to the wire rope 9 when the latter and thus the fabric 6 are tensioned.

Bei ungespannten Seilen 9, d.h. ausgefahrener Spindel 11 und damit losem Stoff 6, kommt das rückwärtige Ende 19 der Klinke 15 in Anlage mit der Platte 21, wodurch die Klinke 15 aus der Verzahnung 13 ausrastet und die Stoffwellen 5 frei drehbar sind (Figur 3). Eine Feder 39 in der Scheibe 8 dreht diese, wenn kein Zug an den Seilen 9 wirkt, derart, dass die Seile 9 auf die Scheiben 8 aufgewickelt werden. Ein Drebereich der Scheiben 8 von ca. 90 bis 100° ist ausreichend.With untensioned ropes 9, i.e. extended spindle 11 and thus loose material 6, the rear end 19 of the pawl 15 comes into contact with the plate 21, whereby the pawl 15 disengages from the toothing 13 and the material shafts 5 are freely rotatable (FIG. 3). A spring 39 in the disk 8 rotates the latter when there is no tension on the ropes 9 in such a way that the ropes 9 are wound onto the disks 8. A rotation range of the disks 8 of approximately 90 to 100 ° is sufficient.

Der Motor 12 und die Spindelmutter 14, die mit den Seilen 9 verbunden sind, sind in einer an der Säule 1 angebrachten Führung 17, z. B. einer Nut, frei längsverschiebbar, jedoch gegen Verdrehung gesichert geführt. Mit einer Klemmvorrichtung 20, z. B. einem Jaccardhebel, am Motor 12 kann dieser an jeder beliebigen Stelle längs der Führung 17 arretiert werden.The motor 12 and the spindle nut 14, which are connected to the ropes 9, are in a guide 17 attached to the column 1, for. B. a groove, freely longitudinally displaceable, but secured against rotation. With a clamping device 20, for. B. a Jaccard lever on the motor 12, this can be locked at any point along the guide 17.

Zwischen dem Seil 9 und der Spindelmutter 14 ist vorzugsweise ein Spannungsmessgerät 22 eingesetzt, mit dem bei Erreichen der eingestellten Spannung der Antriebsmotor 12 ausgeschaltet werden kann. Das Spannungsmessgerät 22 kann beispielsweise aus einem Tellerfederpaket 23 bestehen, das in einer Hülse 27 eingesetzt ist. Die Hülse 227 weist stirnseitig eine Öffnung 29 auf, durch welche das Ende einer an der Spindelmutter 14 befestigten Zugstange 30 hindurchgeführt ist. Mit einer auf das Ende der Zugstange 30 aufgesetzten Scheibe 31 wird das zwischen der Scheibe 31 und dem stirnseitigen Ende der Hülse se 27 liegende Tellerfederpaket 23 gespannt.Between the cable 9 and the spindle nut 14, a tension measuring device 22 is preferably used, with which the drive motor 12 can be switched off when the set tension is reached. The tension measuring device 22 can consist, for example, of a plate spring assembly 23 which is inserted in a sleeve 27. The end of the sleeve 227 has an opening 29 through which the end of a pull rod 30 fastened to the spindle nut 14 is passed. With a disc 31 placed on the end of the pull rod 30, that between the disc 31 and the front end of the sleeve se 27 lying plate spring assembly 23 tensioned.

Radial von der Scheibe 31 abstehend und durch einen Längsschlitz 35 in der Hülse 27 hindurchragend ist ein Gewindebolzen 33 vorgesehen. Auf dem Gewindebolzen 33 sitzt eine Stellmutter 37 mit konischer Mantelfläche und Skala. Unterhalb der Stellmutter 37 ist ein Endschalter 25 an der Hülse 27 befestigt. Ist die Stellmutter 37 bis nahe an die Hülse 27 eingeschraubt, so ist der Federweg, der zurückgelegt werden muss, bis der Endschalter 25 berührt wird grösser, als wenn die Stellmutter 37 nur wenig eingeschraubt ist. Die Spannung in den Drahtseilen 9, bzw. dem Stoff 6 kann entsprechend der Lage der Stellmutter 37 eingestellt werden.A threaded bolt 33 is provided projecting radially from the disk 31 and projecting through a longitudinal slot 35 in the sleeve 27. An adjusting nut 37 with a conical lateral surface and scale sits on the threaded bolt 33. A limit switch 25 is attached to the sleeve 27 below the adjusting nut 37. If the adjusting nut 37 is screwed in close to the sleeve 27, the spring travel that must be covered until the limit switch 25 is touched is greater than if the adjusting nut 37 is screwed in only a little. The tension in the wire cables 9 or the fabric 6 can be adjusted according to the position of the adjusting nut 37.

Die Funktionsweise der Vorrichtung wird im folgenden beschrieben:

  • Von Hand oder mit einem in den Figuren nicht dargestellten Antrieb wird die obere oder die untere Stoffwelle 5 solange gedreht, bis der zu bestickende Bereich des Stoffes 6 ungefähr vor den Nadeln in der Ebene A liegt.
The operation of the device is described below:
  • The upper or lower fabric shaft 5 is rotated by hand or with a drive (not shown in the figures) until the area of the fabric 6 to be embroidered lies approximately in front of the needles in plane A.

Nun kann der Motor 12 in Gang gesetzt und mit der Spindel 11 die Spindelmutter 14 näher an den Motor 12 herangeführt werden. Die Seillänge zwischen den beiden Scheiben 8 wird dadurch verkürzt. Bei diesem Vorgang entfernen sich die beiden Platten 21 von den Enden 19 der Klinken 15. Die Klinken 15 schwenken unter dem Einfluss der auf sie wirkenden Federkraft und gelangen in Eingriff mit der Verzahnung 13 der Stoffwellen 5 und drehen diese mit. Die untere Stoffwelle 5 bewegt sich dabei im Uhrzeigersinn, die obere im Gegenuhrzeigersinn: der Stoff 6 wird gespannt. Wenn das Tellerfederpaket 23 so weit zusammengedrückt ist, dass die Stellmutter 37 in Kontakt mit dem Endschalter 25 gelangt, wird der Motor 12 ausgeschaltet.Now the motor 12 can be started and the spindle nut 14 can be brought closer to the motor 12 with the spindle 11. This shortens the rope length between the two disks 8. In this process, the two plates 21 move away from the ends 19 of the pawls 15. The pawls 15 pivot under the influence of the spring force acting on them and come into engagement with the toothing 13 of the material shafts 5 and rotate them. The lower fabric shaft 5 moves clockwise, the upper one counterclockwise: the fabric 6 is stretched. When the plate spring assembly 23 is compressed so far that the adjusting nut 37 comes into contact with the limit switch 25, the motor 12 is switched off.

Weil der Motor 12 frei längsverschiebbar angebracht ist und mit den Drahtseilen 9 eine Relativbewegung d zum Gatter 3 ausführen kann, wird der Stoff 6 auf beiden Stoffwellen 5 gleichmässig angespannt und - falls die Nadeln bereits in den Stoff eingesteckt sind, ergibt sich ober- und unterhalb der Nadeln genau die gleiche Spannung im Stoff 6.Because the motor 12 is freely displaceable longitudinally and can perform a relative movement d to the gate 3 with the wire cables 9, the fabric 6 is tensioned evenly on both fabric shafts 5 and - if the needles are already inserted into the fabric, the result is above and below the needles have exactly the same tension in the fabric 6.

Sind die Nadeln nicht eingesteckt, so kann der Stoff 6 in gespanntem Zustand absolut genau an die richtige Stelle vor die Nadeln gebracht werden. Je nach der freien Seillänge oberhalb des Spannungsmessgerätes 22, bzw. unterhalb des Motors 12 kann der Stoff 6 ohne entspannt zu werden in der Höhe eingestellt werden.If the needles are not inserted, the fabric 6 can be brought absolutely exactly in the correct position in front of the needles in the tensioned state. Depending on the free rope length above the tension measuring device 22 or below the motor 12, the material 6 can be adjusted in height without being relaxed.

Während des Stickens wird der Motor 12 mit der Klemmvorrichtung 20 festgestellt und damit auch der Stoff 6 unverrückbar gehalten.During the embroidery, the motor 12 is locked with the clamping device 20 and thus the fabric 6 is held immovably.

Stellt sich während des Stickens heraus, dass die Spannung im Stoff 6 zu gering ist, kann am Spannungsmessgerät 22 eine höhere Spannung eingestellt und der Motor 12 eingeschaltet werden.If it turns out during embroidery that the tension in the fabric 6 is too low, a higher tension can be set on the tension measuring device 22 and the motor 12 can be switched on.

Zum Entspannen, bzw. für den Weitertransport der bestickten Bereiche des Stoffes 6 werden die Seile 9 durch Rückwärtsdrehen der Spindel 11 entlastet. Infolge der Spannung im Stoff 6 und wegen der Rückstellkraft der Feder 39 in den Scheiben 8 werden die Seile 9 aufgewickelt. Gleichzeitig kehren die Klinken 15 an den Ausgangspunkt zurück und werden dort von den Platten 21, die sich den Scheiben 8 nähern, verschwenkt und ausgerastet. Die Stoffwalzen 5 sind dann in beiden Richtungen frei drehbar.To relax, or for the further transport of the embroidered areas of the fabric 6, the ropes 9 are relieved by turning the spindle 11 backwards. As a result of the tension in the fabric 6 and because of the restoring force of the spring 39 in the disks 8, the ropes 9 are wound up. At the same time, the pawls 15 return to the starting point and are pivoted and disengaged there by the plates 21 which approach the disks 8. The fabric rollers 5 are then freely rotatable in both directions.
