Description

Gegenstand der Erfindung ist eine Vorrichtung zum Besticken von flächenförmigem Nähgut gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for Embroidery of sheet-like sewing material according to the generic term of claim 1.

Es ist bekannt, mit Nähmaschinen, insbesondere Haushaltnähmaschinen, Stickmuster zu erzeugen. Zu diesem Zweck wird das flächenförmige Nähgut, d.h. die Stickunterlage, in einen Stickrahmen eingespannt und der Stickrahmen wird von einem Antrieb, der den Stickrahmen in X- und Y-Richtung bewegen kann, entsprechend dem zu erzeugenden Stickmuster bewegt. Der Antrieb des Stickrahmens befindet sich in einem an den Freiarm der Nähmaschine andockbaren Gehäuse. Dieses ist an der Rückseite mit dem Freiarm und/oder Grundplatte durch eine Kupplung, welche die mechanische Verbindung bildet, verbunden. Der vom Antrieb bewegbare Stickrahmen weist üblicherweise eine Breite auf, welche etwa dem Abstand zwischen dem Nähmaschinenständer und der Nadel entspricht und eine Länge, die allenfalls das Doppelte der Breite ausmacht. Diese verhältnismässig kleine und durch die Gegebenheiten der Nähmaschine eingeschränkte Stickfläche eignet sich nicht für grössere zusammenhängende Stickmuster; sie ist vor allem bestimmt zum Sticken von Monogrammen oder Einzelsujets.
Bei Einzweck-Stickmaschinen und bei Spezialnähmaschinen, welche einen integrierten Antriebsteil für den Stickrahmen im Bereich des Maschinenständers aufweisen, ist es bekannt, Stickrahmen mit zwei oder vier Stickfeldern zu verwenden. Diese Stickrahmen weisen jeweils zwei nebeneinander liegende Rahmenkupplungen auf, mit denen der rechteckige Stickrahmen an zwei nebeneinander liegenden Punkten mit der Stickmaschine bzw. dem Stickrahmenantrieb verbunden werden kann; der quadratische Stickrahmen mit vier Stickfeldern weist vier Kupplungen auf und kann folglich an vier Stellen zur jeweiligen Bearbeitung eines Quadranten angekuppelt werden. Alternativ können die Aufnahmen auch stufenlos entlang des Stickrahmens verschieb- und einstellbar sein.It is known to produce embroidery patterns with sewing machines, in particular household sewing machines. For this purpose, the sheet-like sewing material, ie the embroidery pad, is clamped in an embroidery frame and the embroidery frame is moved by a drive which can move the embroidery frame in the X and Y directions in accordance with the embroidery pattern to be produced. The drive of the embroidery frame is located in a housing that can be docked onto the free arm of the sewing machine. This is connected at the back to the free arm and / or base plate by a coupling that forms the mechanical connection. The embroidery frame that can be moved by the drive usually has a width that corresponds approximately to the distance between the sewing machine stand and the needle and a length that is at most twice the width. This relatively small embroidery area, which is limited by the conditions of the sewing machine, is not suitable for larger, coherent embroidery patterns; it is primarily intended for embroidering monograms or single subjects.
With single-purpose embroidery machines and with special sewing machines which have an integrated drive part for the embroidery frame in the area of the machine stand, it is known to use embroidery frames with two or four embroidery fields. These embroidery frames each have two adjacent frame couplings, with which the rectangular embroidery frame can be connected to the embroidery machine or the embroidery frame drive at two adjacent points; the square embroidery hoop with four embroidery fields has four couplings and can therefore be coupled at four points for processing a quadrant. Alternatively, the recordings can also be moved and adjusted continuously along the embroidery frame.

Aufgabe der vorliegenden Erfindung ist die Schaffung eines Stickrahmenantriebs für Sockel- und Freiarm-Nähmaschinen, mit dem Stickrahmen mit ein- bis mehrfacher Normstickfläche angetrieben werden können. The object of the present invention is to create a Embroidery hoop drives for plinth and free arm sewing machines, with the embroidery hoop with one or more Standard embroidery area can be driven.

Gelöst wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1.This problem is solved by a device with the Features of claim 1.

Die Zwischenschaltung eines Distanzadapters zwischen den Freiarm oder den Sockel der Nähmaschine und die Stickvorrichtung mit dem darin angeordneten Stickrahmenantrieb ermöglicht es, den zur Verfügung stehenden Raum zwischen der Nadelachse und dem Ständer der Nähmaschine, an welchem der Freiarm befestigt ist, in seiner vollen Grösse als Manövrierraum des Stickrahmens zu nutzen. In einer bevorzugten Ausgestaltung der Erfindung bildet die Zubehörbox, in welcher die Nähutensilien untergebracht werden können und welche, wenn keine engen rohrförmigen Teile bearbeitet werden, am Unterarm befestigt ist, den Distanzadapter. Es müssen folglich keine zusätzlichen Maschinenteile aufbewahrt oder zugekauft werden, um aus der Nähmaschine und einer Stickvorrichtung eine solche zu machen, mit der um ein mehrfaches grössere Stickflächen bearbeitet werden können.The interposition of a distance adapter between the Free arm or the base of the sewing machine and the Embroidery device with the arranged therein Embroidery hoop drive makes it available standing space between the needle axis and the stand of the Sewing machine to which the free arm is attached in its full size as the maneuvering space of the embroidery hoop use. In a preferred embodiment of the invention forms the accessory box in which the sewing utensils can be accommodated and which if not tight tubular parts are machined on the forearm is attached, the distance adapter. So it must no additional machine parts are kept or to be bought out from the sewing machine and one Embroidery device to make one with the order of one multiple larger embroidery areas can be processed.

An das vordere Ende 19 des Freiarms 3 schliesst eine Stickvorrichtung 21 an. Letztere liegt auch satt an der Rückseite 23 des Freiarms 3 an und ist durch nicht dargestellte Kupplungsmittel mit der Maschine 2 mechanisch verbunden. Auf der Stickvorrichtung 21 ist ein Stickrahmenträger 25 in X-Richtung antreibbar gelagert. Am Stickrahmenträger 25 ist weiter in Y-Richtung verfahrbar ein Stickrahmen 27 befestigt. Eine mögliche Ausbildung der Antriebsorgane für den Stickrahmen 27 ist im Deutschen Gebrauchsmuster 29614512 Ul beschrieben. Verschiedene weiter Antriebsmittel für die X-/Y-Bewegungen eines Stickrahmens sind aus dem Stand der Technik hinlänglich bekannt und werden daher nicht im Detail erläutert. 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 2, wie sie in den Figuren 1 bis 3 dargestellt ist, entspricht dem Stand der Technik.One closes at the front end 19 of the free arm 3 Embroidery device 21. The latter is also full of Back 23 of the free arm 3 and is not through Coupling means shown with the machine 2 mechanically connected. On the embroidery device 21 is a Embroidery frame support 25 drivably mounted in the X direction. At the Embroidery frame support 25 can be moved further in the Y direction an embroidery frame 27 attached. A possible education of Drive elements for the embroidery frame 27 is in German Utility model 29614512 Ul described. Various further drive means for the X / Y movements of a Embroidery frames are adequate from the prior art known and are therefore not explained in detail. By an appropriately trained, not described in detail or shown control, the embroidery hoop 27 in move in a known manner on a programmable path become. Accordingly, the sewing machine 2 freely programmable patterns on a textile structure, the is clamped in the hoop 27 are generated. The mutual position between the embroidery device 21 and the Free arm 3 of the sewing machine 2, as shown in Figures 1 to 3 corresponds to the prior art.

In den schematischen Darstellungen in den Figuren 4 bis 11 sind nur noch die für die Erfindung wesentlichen Teile bzw. die Umrisse der Nähmaschine 2 und der Stickvorrichtung 21 dargestellt.In the schematic representations in FIGS. 4 to 11 are only the parts essential to the invention or the outlines of the sewing machine 2 and the Embroidery device 21 shown.

In Figur 4, welche die erfinderischen Merkmale aufweist, ist nun zwischen die Stickvorrichtung 21 und den Freiarm 3 ein Distanzadapter 29 eingesetzt, welcher bewirkt, dass die Stickvorrichtung 21 in Längsrichtung des Freiarms 3, d.h. in X-Richtung beabstandet vor der Nähmaschine 1 zu liegen kommt. Diese Verschiebung um den Betrag R1 erlaubt es, einen Stickrahmen 27 von doppelter Kantenlänge wie derjenige in Figur 2 auf die Stickvorrichtung 21 aufzusetzen. Die Nadel 11 kann bei dieser Stellung bis in der Mitte der Stickfläche innerhalb des Stickrahmens 27 einstechen und, in Y-Richtung gesehen, den gesamten Quadranten A bearbeiten. Der Stickrahmen 27 ist für die Bearbeitung des ersten Quadranten "A" an der Stelle KI durch eine Rahmenkupplung 28 mit der Stickvorrichtung verbunden (Figur 7). Für die Bearbeitung des zweiten Quadranten "B" wird der Stickrahmen 27 an der Stelle KII befestigt (Figur 8). Dadurch ergibt sich eine Verschiebung des Stickrahmens 27 in Y-Richtung. Figur 9 zeigt die Situation, in welcher der Stickrahmen 27 um 180° um dessen Zentrum gedreht ist und die Bearbeitung des dritten Quadranten "C" erfolgt. Nun ist der Stickrahmen 27 an der Befestigungs- oder Kupplungsstelle KIII mit der Stickvorrichtung 21 verbunden. Zur Bearbeitung des vierten Quadranten "D" erfolgt die Verbindung des Stickrahmens 21 an der Stelle KIV (Figur 10). Die Justierung des Stickrahmens 27 unter der Nadel 11 nach dem Umkuppeln erfolgt auf elektronischem Weg durch die Steuerung oder durch eine mechanische Justage.In FIG. 4, which has the inventive features, a spacer adapter 29 is now inserted between the embroidery device 21 and the free arm 3, which causes the embroidery device 21 to lie in front of the sewing machine 1 in the longitudinal direction of the free arm 3, ie in the X direction is coming. This shift by the amount R1 allows an embroidery frame 27 of twice the edge length as that in FIG. 2 to be placed on the embroidery device 21. In this position, the needle 11 can penetrate into the center of the embroidery area within the embroidery frame 27 and, viewed in the Y direction, machine the entire quadrant A. The embroidery frame 27 is connected to the embroidery device for processing the first quadrant "A" at the point K I by a frame coupling 28 (FIG. 7). For the processing of the second quadrant "B", the embroidery frame 27 is attached at the point K II (FIG. 8). This results in a displacement of the embroidery frame 27 in the Y direction. FIG. 9 shows the situation in which the embroidery frame 27 is rotated by 180 ° around its center and the third quadrant “C” is processed. The embroidery frame 27 is now connected to the embroidery device 21 at the fastening or coupling point K III . To process the fourth quadrant "D", the embroidery frame 21 is connected at the point K IV (FIG. 10). The adjustment of the embroidery frame 27 under the needle 11 after the coupling is done electronically by the control or by a mechanical adjustment.

In der Ausgestaltung der Erfindung gemäss Figur 5 wird die Stickvorrichtung 21 durch den Distanzadapter 29 in X-Richtung um den Betrag R2 vom Freiarm 3 entfernt befestigt. Es besteht nun kein direkter Kontakt zwischen der Stickvorrichtung 21 und dem Freiarm 3. Der Distanzadapter 29 umfasst den Freiarm 3 auf drei Seiten. Durch diesen zusätzlichen seitlichen Abstand kann ein entsprechend noch grösserer Stickrahmen 27 verwendet werden.In the embodiment of the invention according to FIG. 5, the embroidery device 21 is fastened by the distance adapter 29 in the X direction by the amount R 2 from the free arm 3. There is now no direct contact between the embroidery device 21 and the free arm 3. The distance adapter 29 comprises the free arm 3 on three sides. Due to this additional lateral distance, a correspondingly larger embroidery frame 27 can be used.

In der Ausgestaltung der Erfindung nach Figur 6 erfolgt sowohl eine Distanzierung der Stickvorrichtung 21 vom Freiarm 3 sowohl in X- als auch in Y-Richtung um die Beträge R1 und S1. In the embodiment of the invention according to FIG. 6, the embroidery device 21 is distanced from the free arm 3 both in the X and Y directions by the amounts R 1 and S 1 .

Der Distanzadapter 29 wird mittels ersten Kupplungsmitteln am Freiarm 3 und/oder an der Grundplatte und mittels zweiten Kupplungsmitteln mit der Stickvorrichtung 21 vorzugweise formschlüssig verbunden. Die beiden Kupplungsmittel sind nicht sichtbar. Die Energiezufuhr für die Antriebe in der Stickvorrichtung 21 kann durch die besagten Kupplungsmittel oder über ein Kabel der Stickvorrichtung 21 erfolgen.The distance adapter 29 is by means of first coupling means on the free arm 3 and / or on the base plate and by means of second coupling means with the embroidery device 21st preferably positively connected. The two Coupling agents are not visible. The energy supply for the drives in the embroidery device 21 can by said coupling means or via a cable of the Embroidery device 21 take place.

In einer besonders vorteilhaften Ausgestaltung der Erfindung dient der Distanzadapter 29 gleichzeitig als Zubehörbox, bzw. die üblicherweise mit der Nähmaschine 2 gelieferte Zubehörbox, deren Oberfläche - verbunden mit dem Freiarm 3 - die Nähfläche vergrössert, dient als Distanzadapter 29. Auf diese Weise muss einzig die Zubehörbox mit den Kupplungsmitteln für die Stickvorrichtung bestückt werden bzw. der Distanzadapter 29 muss einen Deckel, eine Schub- oder eine Drehlade aufweisen und im Innern die entsprechenden Halterungen für die Zubehörteile enthalten.In a particularly advantageous embodiment of the Invention serves the distance adapter 29 as a Accessory box, or usually with the sewing machine 2 supplied accessory box, its surface - connected with the free arm 3 - the sewing area increases, serves as Distance adapter 29. In this way, only the Accessory box with the coupling means for the Embroidery device or the distance adapter 29 must have a lid, a drawer or a rotating drawer have and inside the appropriate brackets for the accessories included.

In Figur 11 liegt die Stickvorrichtung auf einer seitlich am Distanzadapter 29 angeordneten Aufnahmeplatte 29'. Dies ermöglicht es, die Stickvorrichtung 21 auch an Nähmaschinen 1 anzufügen, bei denen die Stichplatte höher liegt als die Oberfläche der (herkömmlichen Standard)Stickvorrichtung 21. In Figure 11, the embroidery device is on one side on the distance adapter 29 arranged mounting plate 29 '.
