Description

Gegenstand der Erfindung ist ein Verfahren zum Besticken von rohrförmigem Nähgut gemäss Oberbegriff des Patentanspruches 1 und eine Vorrichtung zum Besticken von rohrförmigem Nähgut gemäss Oberbegriff des Patentanspruches 3.The invention relates to a method for embroidery of tubular sewing material according to the preamble of Claim 1 and a device for embroidering tubular sewing material according to the preamble of Claim 3.

Es ist bekannt, an Nähmaschinen Stick-Vorrichtungen anzubauen, um die Nähmaschine auch als Stickmaschine mit gesteuertem Stickrahmen nutzen zu können. Im Deutschen Gebrauchsmuster DE-29614512 U1 ist der Stickrahmen am Stickrahmenträger einer derartigen Stickvorrichtung in X- und Y-Richtung verschiebbar gelagert. Die Stickvorrichtung ist als Baueinheit ausgebildet, weist einen im wesentlichen L-förmigen Grundriss auf und liegt sowohl rückseitig der Nähmaschine als auch stirnseitig satt am Freiarm an und ist mit diesem lösbar verbunden. Die Oberfläche der Stickvorrichtung und die Oberfläche des Freiarmes bilden eine gemeinsame geschlossene Arbeitsfläche.It is known to embroider devices on sewing machines to use the sewing machine as an embroidery machine controlled embroidery hoop. In German utility model DE-29614512 U1 is the Embroidery frame on the embroidery frame holder of such Embroidery device can be moved in the X and Y directions stored. The embroidery device is as a unit formed, has an essentially L-shaped Floor plan and is both on the back of the sewing machine as well as on the face of the free arm and is with this releasably connected. The surface of the embroidery device and the surface of the free arm form a common one closed work surface.

Aus der japanischen Patentanmeldung 04-354969 ist eine weitere Stickvorrichtung bekannt, die ebenfalls L-förmig ausgebildet ist und an der Vorderseite sowie der Stirnseite des Freiarmes lückenlos anliegt und fest mit der Maschine verbunden ist. Die Zuführung der elektrischen Energie und der Steuersignale erfolgt über eine freiliegende flexible Leitung.
Mit den bekannten Vorrichtungen können auf flächenförmigen Stoffen Stickmuster erzeugt werden. Nicht möglich ist allerdings die Bestickung von rohr- oder schlauchförmigen Textilien wie Blusenärmel oder Ärmel von T-Shirts und dergleichen. Dies ist nachteilig.From the Japanese patent application 04-354969 a further embroidery device is known, which is also L-shaped and rests seamlessly on the front and the front of the free arm and is firmly connected to the machine. The electrical energy and the control signals are supplied via an exposed flexible line.
With the known devices, embroidery patterns can be created on sheet-like fabrics. However, embroidery of tubular or tubular textiles such as blouse sleeves or sleeves of T-shirts and the like is not possible. This is a disadvantage.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Verfahrens und einer Vorrichtung, mit denen sowohl das Besticken von flächenförmigen als auch von rohrförmigen Gebilden möglich ist.The object of the present invention is therefore to create a method and a device with which both embroidery of flat as well as of tubular structures is possible.

Gelöst wird diese Aufgabe durch ein Verfahren gemäss den Merkmalen des Patentanspruches 1 sowie durch eine Vorrichtung gemäss den Merkmalen des Patentanspruches 3. This task is solved by a procedure according to Features of claim 1 and by a Device according to the features of claim 3.

Vorteilhafte Ausgestaltungen der Erfindungen sind in den abhängigen Ansprüchen definiert.Advantageous embodiments of the inventions are in the dependent claims defined.

Überraschenderweise gelingt es durch die Ausbildung eines Zwischenraumes zwischen dem Freiarm und der Stickvorrichtung, ungehindert rohrförmige Textilien und dergleichen in einen Stickrahmen zu spannen und über den Freiarm zu ziehen, um sie mit Stickereien zu versehen. Durch den Einsatz eines Distanzhalters wird genügend Raum geschaffen, um die rohrförmigen Teile leicht einführen und während des Stickens bewegen zu können. Am Distanzhalteelement sind Befestigungsmittel vorgesehen, welche eine stabile mechanische Verbindung zwischen der Stickvorrichtung und der Grundplatte der Nähmaschine herstellen. Die für die Steuerung des Stickrahmens erforderliche elektrische Verbindung zwischen Nähmaschine und Stickvorrichtung, welche üblicherweise über eine flexible Leitung erfolgt, bleibt unverändert.Surprisingly, it can be done by training one Space between the free arm and the Embroidery device, unhindered tubular textiles and the same in a hoop and over the Pull free arm to embroider them. By using a spacer there is enough space created to easily insert the tubular parts and to be able to move while embroidering. At the Spacers are provided with fasteners, which is a stable mechanical connection between the Embroidery device and the base plate of the sewing machine produce. The one for controlling the embroidery hoop required electrical connection between sewing machine and embroidery device, which usually has a flexible management takes place, remains unchanged.

Die in Figur 1 dargestellte Nähmaschine 2 wird im einzelnen nicht näher erläutert, da deren Aufbau aus dem Stand der Technik hinlänglich bekannt und für den Erfindungsgegenstand unerheblich ist. Es werden zudem nur die für die Erläuterung der Erfindung notwendigen Teile der Nähmaschine 2 bezeichnet und näher erläutert. Mit dem Bezugszeichen 1 ist das Nähmaschinengehäuse bezeichnet, welches auf einer Grundplatte 5 aufgesetzt ist und eine im wesentlichen L-förmige Gestalt aufweist. Am vertikalen Schenkel 4 des Maschinengehäuses 1 ist mit Abstand zur Grundplatte 5 der Freiarm 3 ausgebildet. In dessen freiem Ende ist, nicht sichtbar, unterhalb des Stichlochs 7 der Greifer antreibbar gelagert. Oberhalb des Stichlochs 7 ist an der Nadelstange 9 eine Nadel 11 eingesetzt. Auf der der Bedienungsperson zugekehrten Frontseite des Maschinengehäuses 1 ist ein Bildschirm 13 schematisch als Rechteck dargestellt. Alternativ könnte auch eine anders ausgebildete Anzeige- oder Bedienungseinheit vorgesehen werden. Ebenfalls am Maschinengehäuse 1 ist auf der gleichen Seite eine Rollkugel 15 vorgesehen. Die zugeordneten Betätigungstasten sind mit 16 bezeichnet. Eine weitere Tastenreihe 17 dient dazu, Sonderfunktionen anzuwählen. Sämtliche für die Fadenführung notwendigen Elemente und der Faden sind nicht näher bezeichnet oder dargestellt, weil sie für die Beschreibung der Erfindung und deren Verständnis nicht notwendig sind und deren Ausbildung auf die Erfindung keinen Einfluss hat.
An das vordere Ende 19 des Freiarms 3 schliesst eine Stickvorrichtung 21 an. Letztere liegt auch satt an der Rückseite 23 des Freiarms 3 bündig an und ist durch nicht dargestellte Mittel mit der Maschine 2 mechanisch verbunden. Auf der Stickvorrichtung 21 ist ein Stickrahmenträger 25 in X-Richtung verschiebbar gelagert. Am Stickrahmenträger 25 ist in Y-Richtung verfahrbar ein Stickrahmen 27 befestigt. Eine mögliche Ausbildung der Antriebsorgane für den Stickrahmen 27 ist im Deutschen Gebrauchsmuster 29614512 U1 beschrieben. Die Antriebsmittel für die X-/Y-Bewegungen eines Stickrahmens sind aus dem Stand der Technik hinlänglich bekannt und müssen daher nicht im Detail erläutert werden. Durch eine entsprechend ausgebildete, nicht näher beschriebene oder dargestellte Steuerung kann der Stickrahmen 27 in bekannter Weise auf einer programmierbaren Bahn verfahren werden. Dementsprechend können mit der Nähmaschine 2 freiprogrammierbare Muster auf einem textilen Gebilde, das im Stickrahmen 27 eingespannt ist, erzeugt werden. Die gegenseitige Lage zwischen der Stickvorrichtung 21 und dem Freiarm 3 der Nähmaschine, wie sie in den Figuren 1 und 2 dargestellt ist, entspricht dem Stand der Technik.The sewing machine 2 shown in FIG. 1 is not explained in detail, since its structure is well known from the prior art and is irrelevant to the subject matter of the invention. In addition, only the parts of the sewing machine 2 necessary for the explanation of the invention are designated and explained in more detail. The reference numeral 1 denotes the sewing machine housing, which is placed on a base plate 5 and has an essentially L-shaped shape. The free arm 3 is formed on the vertical leg 4 of the machine housing 1 at a distance from the base plate 5. In its free end, not visible, the gripper is drivably mounted below the tap hole 7. A needle 11 is inserted above the tap hole 7 on the needle bar 9. On the front side of the machine housing 1 facing the operator, a screen 13 is shown schematically as a rectangle. Alternatively, a differently designed display or control unit could also be provided. A trackball 15 is also provided on the machine housing 1 on the same side. The assigned actuation keys are designated 16. Another row of keys 17 is used to select special functions. All the elements necessary for the thread guide and the thread are not designated or shown in detail because they are not necessary for the description of the invention and its understanding and their design has no influence on the invention.
An embroidery device 21 connects to the front end 19 of the free arm 3. The latter also lies flush against the rear side 23 of the free arm 3 and is mechanically connected to the machine 2 by means not shown. An embroidery frame carrier 25 is mounted on the embroidery device 21 so as to be displaceable in the X direction. An embroidery frame 27 is attached to the embroidery frame carrier 25 so as to be movable in the Y direction. A possible design of the drive elements for the embroidery frame 27 is described in German utility model 29614512 U1. The drive means for the X / Y movements of an embroidery frame are well known from the prior art and therefore do not have to be explained in detail. The embroidery frame 27 can be moved in a known manner on a programmable path by means of a correspondingly designed control, not described or shown in detail. Accordingly, freely programmable patterns can be produced with the sewing machine 2 on a textile structure which is clamped in the embroidery frame 27. The mutual position between the embroidery device 21 and the free arm 3 of the sewing machine, as shown in Figures 1 and 2, corresponds to the prior art.

In der erfindungsgemässen Anordnung gemäss den Figuren 3 und 4 liegt die Stickvorrichtung 21 sowohl in X- als auch Y-Richtung unter Bildung eines Zwischenraums in einem Abstand a bzw. b zur Stirnfläche 19 bzw. Rückseite 23 des Freiarms 3. Zwischen der Grundplatte 5 der Nähmaschine 2 und der Stickvorrichtung 21 ist ein Distanzhalter 29 eingefügt. Dieser ist fest mit der Grundplatte 5 der Nähmaschine 2 und einem geeignet ausgebildeten Sockel 31 der Stickvorrichtung 21 verbunden. Die Höhe h des Distanzhalters 29 entspricht in etwa der Höhe der Grundplatte 5, so dass der freie Zugang zum Einführen von rohrförmigem Nähgut über das freifliegende Ende 19 des Freiarms 3 gewährleistet ist.In the arrangement according to the invention according to FIGS. 3 and 4 is the embroidery device 21 in both X and Y direction to form a space in one Distance a and b to the end face 19 and rear 23 of the Free arm 3. Between the base plate 5 of the sewing machine 2 and the embroidery device 21 is a spacer 29 inserted. This is fixed to the base plate 5 of the Sewing machine 2 and a suitably designed base 31 the embroidery device 21 connected. The height h of the Spacer 29 corresponds approximately to the height of the Base plate 5 so that free access to insert tubular sewing material over the free-flying end 19 of the Freiarms 3 is guaranteed.

Der Distanzhalter 29 umfasst mechanische Halte- und Zentriermittel, welche eine positionsgenaue Verbindung der Stickvorrichtung 21 mit der Grundplatte 5 bzw. mit der Nähmaschine 2 ermöglichen. Als Befestigungs- und Zentriermittel dienen ein rippenartiger, horizontaler Nocken 33 und ein zylindrischer Nocken 35 mit vertikaler Achse, welche am Distanzhalter 29 ausgebildet sind. Die beiden Nocken 33 und 35 greifen in entsprechend gestaltete Ausnehmungen 37 und 39 an der Grundplatte 5 ein (Figur 5). Die Verbindung zwischen der Stickvorrichtung 21 und dem Distanzhalter 29 erfolgt analog. Somit kann mit den gleichen Mitteln auch eine direkte Verbindung zwischen der Stickvorrichtung 21 und der Nähmaschine 2 hergestellt werden, wenn flächenförmige Textilien bestickt werden sollen. Ein Nocken 41, der die Oberfläche des Distanzhalters 29 vertikal überragt und durch eine Ausnehmung 43 von unten in das Gehäuse der Stickvorrichtung 21 eingreift, wirkt mit einem Tastmittel 45 zusammen, um das Vorhandensein des Distanzhalters 29 abzutasten. Wenn die Stickvorrichtung 21 mittels Distanzhalter 29 an der Nähmaschine 2 befestigt ist, löst das Tastmittel 45 ein Signal an die Steuervorrichtung aus, so dass diese nur noch Stickmuster-Steuerdaten für einen eingeschränkten Stickbereich freigibt. Das Tastmittel 45 besteht vorzugsweise aus einer Lichtschranke, welche durch den als Blende wirkenden Nocken 41 betätigt wird. Die elektrischen Leistungs- und Steuerungsverbindungen zwischen der Stickvorrichtung 21 und der Nähmaschine 2 können in herkömmlicher Weise über ein aussengeführtes Kabel (nicht dargestellt) oder durch ebenfalls nicht dargestellte Steckverbindungen erstellt werden. Die Steckverbindungen können derart ausgebildet sein, dass sie gleichzeitig mit dem Zusammenstecken des Distanzhalters 29 mit der Grundplatte 5 der Nähmaschine 2 und mit der Stickvorrichtung 21 verbunden werden.The spacer 29 includes mechanical holding and Centering means, which a precise connection of the Embroidery device 21 with the base plate 5 or with the Allow sewing machine 2. As a fastening and Centering means serve a rib-like, horizontal Cam 33 and a cylindrical cam 35 with a vertical Axis, which are formed on the spacer 29. The both cams 33 and 35 engage in appropriately designed Recesses 37 and 39 on the base plate 5 (Figure 5). The connection between the embroidery device 21 and the Spacer 29 is carried out analogously. Thus, with the same means also a direct connection between the Embroidery device 21 and the sewing machine 2 produced when embroidering sheet-like textiles should. A cam 41 that the surface of the Spacer 29 projects vertically and through a Recess 43 from below in the housing of Embroidery device 21 engages, acts with a probe 45 together to determine the presence of the spacer 29 to feel. If the embroidery device 21 by means of Spacer 29 is attached to the sewing machine 2, releases the feeler 45 sends a signal to the control device, so this is just embroidery control data for one restricted embroidery area. The feeler 45 consists preferably of a light barrier, which through the cam 41 acting as an aperture is actuated. The electrical power and control connections between the embroidery device 21 and the sewing machine 2 can in a conventional manner via an outside Cable (not shown) or through also not shown plug connections are created. The Plug connections can be designed such that they simultaneously with the plugging of the spacer 29 with the base plate 5 of the sewing machine 2 and with the Embroidery device 21 are connected.

Wenn die Stickvorrichtung 21 mit Hilfe des Distanzhalters 29 mit der Nähmaschine 2 verbunden ist, liegt die Stickvorrichtung 21 nicht mehr am Freiarm 3 an, sondern ist gegenüber diesem um die Abstände a, bzw. b verschoben (Fig. 4). Dadurch ergibt sich eine eingeschränkte Nutzung der Stickfläche gegenüber der Anwendung der Stickvorrichtung 21 gemäss Fig. 1 und 2. Dementsprechend ist die Verwendung eines speziellen Stickrahmens 27a erforderlich, welcher mit Mitteln zum Überbrücken des zwischen Freiarm 3 und Stickvorrichtung 21 gebildeten Zwischenraums ausgestattet ist. Diese Mittel bestehen aus einem Brückenteil 30, welcher vorzugsweise einstückig mit dem Stickrahmen 27a ausgebildet ist. Der Stickrahmen 27a wird in bekannter Weise mit dem Stickrahmenträger 25 verbunden, wobei Mittel zum Indentifizieren des Stickrahmens gemäss dem Deutschen Gebrauchsmuster DE 29612102 U1 vorgesehen sein können.
Wie bereits erwähnt wird bei der Verwendung der Stickvorrichtung 21 mit Distanzhalter 29 ein Signal ausgelöst, welches bewirkt, dass die X-/Y-Steuervorrichtung für den Stickrahmen 27a nur noch Bewegungen in einem eingeschränkten Bereich zulässt, welcher den Grössenverhältnissen des speziellen Stickrahmens 27a entspricht.When the embroidery device 21 is connected to the sewing machine 2 with the aid of the spacer 29, the embroidery device 21 is no longer in contact with the free arm 3, but is shifted relative to it by the distances a or b (FIG. 4). This results in a limited use of the embroidery area compared to the use of the embroidery device 21 according to FIGS. 1 and 2. Accordingly, the use of a special embroidery frame 27a is necessary, which is equipped with means for bridging the space formed between the free arm 3 and the embroidery device 21. These means consist of a bridge part 30, which is preferably formed in one piece with the embroidery frame 27a. The embroidery hoop 27a is connected in a known manner to the embroidery hoop carrier 25, whereby means for identifying the embroidery hoop can be provided in accordance with German utility model DE 29612102 U1.
As already mentioned, when using the embroidery device 21 with the spacer 29, a signal is triggered, which has the effect that the X / Y control device for the embroidery frame 27a only permits movements in a restricted area which corresponds to the size relationships of the special embroidery frame 27a.

Alternativ zu den beschriebenen mechanischen Verbindungsmitteln können selbstverständlich auch anders ausgebildete geeignete Andock- und Distanzhalterelemente eingesetzt werden.As an alternative to the described mechanical Lanyards can of course be different trained suitable docking and spacer elements be used.
