Description

Technisches Gebiettechnical field

Die Erfindung betrifft eine Nähmaschine mit einer Bestückungseinrichtung für insbesondere paillettenartige Funktionselemente, wie sie beispielsweise benötigt wird, um Funktionselemente einem beispielsweise für eine Kleidung dienenden Stoff bzw. Textil zuzuführen. Weiterhin betrifft die Erfindung ein Verfahren zum Verbinden eines Funktionselements mit einem Textil, insbesondere mittels einer erfindungsgemäßen Bestückungseinrichtung.The invention relates to a sewing machine with an assembly device for, in particular, sequin-like functional elements, as is required, for example, in order to supply functional elements to a fabric or textile used, for example, for clothing. Furthermore, the invention relates to a method for connecting a functional element to a textile, in particular by means of an assembly device according to the invention.

Stand der TechnikState of the art

Eine Bestückungseinrichtung ist aus der DE 10 2010 020 623 A1 bekannt. Die bekannte Bestückungseinrichtung weist im Wesentlichen zwei Ausführungsformen auf. Bei einer ersten Ausführungsform sind die Elemente in Art einer Endloskette durch Verwendung eines Trägerelements miteinander verbunden. Bei einer zweiten Ausführungsform ist ein schachtartiges Magazin mit einer Abgabeseite vorgesehen. In dem Magazin sind die Elemente vereinzelt und übereinandergestapelt angeordnet. Das Überführen jeweils eines Elements von dem Gurt bzw. dem Magazin zu der Stelle, an der das Element mit dem Stoff bzw. dem Textil verbunden wird, erfolgt bei beiden Ausführungsformen mittels einer Transfereinrichtung, die einen um eine Achse schwenkbaren Arm aufweist. In einer Übernahmeposition des Arms übernimmt dieser jeweils ein Element aus dem Magazin bzw. der Kette und schwenkt anschließend in eine Übergabeposition, die mit der gewünschten Befestigungsposition des Elements am Textil ausgerichtet ist. Eine derartige Ausbildung der Transfereinrichtung mit einem schwenkbaren Arm setzt eine exakte Positionierung bzw. Ausrichtung des Arms zu den Elementen und dem Stoff bzw. Textil voraus, damit diese sicher entnommen und positionsgenau abgesetzt werden können. Darüber hinaus liegt die Schwenkachse des Arms oberhalb des Stoffs bzw. Textils in einem Bereich zwischen den bevorrateten Elementen und beispielsweise einer Nähnadel o.ä. der Nähmaschine. Somit nimmt der Arm der Transfereinrichtung oberhalb des Stoffs bzw. Textils einen relativ großen Bauraum ein, was die Zugänglichkeit zu anderen Elementen der Nähmaschine ggf. erschwert.A placement device is from the DE 10 2010 020 623 A1 known. The well-known placement device essentially has two embodiments. In a first embodiment, the elements are connected to one another in the manner of an endless chain by using a carrier element. In a second embodiment, a shaft-like magazine is provided with a delivery side. In the magazine, the elements are arranged individually and stacked one on top of the other. In both embodiments, the transfer of an element from the belt or the magazine to the point at which the element is connected to the fabric or the textile takes place by means of a transfer device which has an arm pivotable about an axis. When the arm is in a take-over position, it takes one element from the magazine or the chain and then pivots into a transfer position, which is aligned with the desired fastening position of the element on the textile. Such a design of the transfer device with a pivotable arm requires exact positioning or alignment of the Arms to the elements and the fabric or textile so that they can be safely removed and set down in the correct position. In addition, the pivot axis of the arm is located above the fabric or textile in an area between the stored elements and, for example, a sewing needle or the like of the sewing machine. The arm of the transfer device thus takes up a relatively large amount of space above the fabric or textile, which may make it difficult to access other elements of the sewing machine.

Offenbarung der ErfindungDisclosure of Invention

Die erfindungsgemäße Nähmaschine mit einer Bestückungseinrichtung für insbesondere paillettenartige Funktionselemente mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass sie eine gegenüber dem Stand der Technik besonders vorteilhafte Ausbildung der Transfereinrichtung aufweist. Insbesondere ermöglicht es die erfindungsgemäße Gestaltung der Transfereinrichtung, die Baugröße und Bauhöhe der Transfereinrichtung bzw. den Raumbedarf oberhalb des Stoffs bzw. Textils zu minimieren, um dadurch eine verbesserte Zugänglichkeit zu erzielen.The sewing machine according to the invention with an assembly device for, in particular, sequin-like functional elements with the features of claim 1 has the advantage that it has a configuration of the transfer device that is particularly advantageous compared to the prior art. In particular, the design of the transfer device according to the invention makes it possible to minimize the size and height of the transfer device or the space requirement above the fabric or textile, in order to thereby achieve improved accessibility.

Hierzu sieht es die Lehre der Erfindung vor, dass die Transfereinrichtung ein linearbeweglich angeordnetes Transferelement mit wenigstens einer Aufnahme für ein Funktionselement aufweist. Es lässt sich somit eine den Bauraum der Transfereinrichtung vergrößernde Rotationsbewegung des Transferelements vermeiden.For this purpose, the teaching of the invention provides that the transfer device has a linearly movable arranged transfer element with at least one receptacle for a functional element. A rotational movement of the transfer element that increases the installation space of the transfer device can thus be avoided.

Vorteilhafte Weiterbildungen der erfindungsgemäßen Bestückungseinrichtung für insbesondere paillettenartige Funktionselemente sind in den Unteransprüchen aufgeführt.Advantageous developments of the assembly device according to the invention, in particular for sequin-like functional elements, are listed in the dependent claims.

Unter Funktionselementen werden nicht nur zu rein der optischen Ausschmückung bzw. Aufwertung dienenden Elementen solche, insbesondere paillettenartigen Funktionselemente verstanden, die eine elektrische bzw. elektronische Funktionalität aufweisen, wie sie beispielsweise erforderlich ist, um eine Spannungsversorgung zu einem Sensor, einem Leuchtelement o.ä. auszubilden. Auch können derartige Funktionselemente als Träger einer elektronischen Schaltung in Form eines integrierten Schaltung (ICs) o.ä., beispielsweise als Bestandteil einer Sensoreinrichtung dienen. Unter einer Nähmaschine wird dabei im Rahmen der Erfindung jede Maschine verstanden, die dazu ausgebildet ist, Funktionselemente unter Verwendung eines insbesondere fadenförmigen, besonders bevorzugt elektrisch leitfähigen Fadens, Garns oder ähnlichem mit dem angesprochenen Stoff bzw. Textil zu verbinden. Es sind somit jegliche Maschinen gemeint, die dazu dienen können, Stick-, Web-, Knüpf- oder ähnliche Verbindungstechniken auszuführen.Functional elements are understood not only as elements serving purely for visual decoration or upgrading, in particular sequin-like functional elements that have an electrical or electronic functionality such as is required, for example, to supply a voltage to a sensor, a light-emitting element or the like. to train. Functional elements of this type can also serve as carriers of an electronic circuit in the form of an integrated circuit (ICs) or the like, for example as part of a sensor device. Within the scope of the invention, a sewing machine is understood to be any machine that is designed to connect functional elements to the material or textile in question using a particularly thread-like, particularly preferably electrically conductive thread, yarn or the like. This means any machine that can be used to carry out embroidery, weaving, knotting or similar connection techniques.

In einer konstruktiv besonders bevorzugten Ausgestaltung des Transferelements ist es vorgesehen, dass das Transferelement als eine in einer Führung angeordnete Leiste und die wenigstens eine Aufnahme für das Funktionselement als Durchgangsöffnung in der Leiste ausgebildet ist.In a structurally particularly preferred embodiment of the transfer element, it is provided that the transfer element is designed as a bar arranged in a guide and the at least one receptacle for the functional element is designed as a through-opening in the bar.

Um eine positions- bzw. winkelgenaue Ausrichtung des Funktionselements bei seiner Befestigung auf dem Stoff bzw. Textil zu ermöglichen, sieht es eine weitere Ausgestaltung der Erfindung vor, dass die wenigstens eine Aufnahme eine der Außenkontur des Funktionselements angepasste Innenkontur aufweist, sodass das Funktionselement in der Aufnahme des Transferelements in einer definierten Position angeordnet ist.In order to enable the functional element to be aligned with a precise position or angle when it is attached to the fabric or textile, a further embodiment of the invention provides that the at least one receptacle has an inner contour adapted to the outer contour of the functional element, so that the functional element in the Recording of the transfer element is arranged in a defined position.

Um beispielsweise auf ein (verstellbares) Element zur Blockierung bzw. zum Fixieren des Funktionselements in der Aufnahme des Transferelements beim Überführen des Funktionselements in Richtung der Übergabeposition verzichten zu können, ist erfindungsgemäß vorgesehen, dass das Transferelement zwischen der Übernahmeposition und der Übergabeposition nahezu spaltfrei oberhalb einer Oberfläche eines mit dem Funktionselement zu verbindenden Textils angeordnet ist. Das Textil bzw. die Oberfläche des Textils wirkt somit gleichzeitig in Art eines Bodens für das Transferelement bzw. das Funktionselement, sodass das Funktionselement innerhalb der Aufnahme in vertikaler Richtung gehalten ist und bei seiner Überführung nicht aus der Aufnahme des Transferelements herausfällt.In order to be able to do without, for example, an (adjustable) element for blocking or fixing the functional element in the receptacle of the transfer element when transferring the functional element in the direction of the transfer position, the invention provides that the transfer element is arranged almost without a gap above a surface of a textile to be connected to the functional element between the transfer position and the transfer position. The textile or the surface of the textile thus simultaneously acts as a kind of base for the transfer element or the functional element, so that the functional element is held in the vertical direction within the receptacle and does not fall out of the receptacle of the transfer element when it is transferred.

In einer ganz besonders bevorzugten Ausgestaltung der Erfindung, die es ermöglicht, mit geringem Handlingsaufwand unterschiedliche Funktionselemente ohne Umrüstzeiten verarbeiten zu können, ist es vorgesehen, dass mehrere Speicherelemente vorgesehen sind, die in Ausrichtung mit der Position der wenigstens einen Aufnahme des Transferelements positionierbar sind.In a very particularly preferred embodiment of the invention, which makes it possible to process different functional elements with little handling effort and without changeover times, it is provided that several storage elements are provided, which can be positioned in alignment with the position of the at least one receptacle of the transfer element.

Eine weitere bevorzugte konstruktive Ausgestaltung der Erfindung sieht vor, dass das Transferelement in der Übergabeposition zum Freistellen des Funktionselements aus seiner Aufnahme im Transferelement senkrecht zur Ebene der Aufnahme in dem Transferelement beweglich angeordnet ist.A further preferred constructional embodiment of the invention provides that the transfer element is movably arranged in the transfer position for releasing the functional element from its receptacle in the transfer element perpendicular to the plane of the receptacle in the transfer element.

Eine besonders kompakte und konstruktiv vorteilhafte Ausgestaltung der Führung für das Transferelement wird erzielt, wenn die Führung für das Transferelement an einem Trägerelement angeordnet ist, wobei das Trägerelement gleichzeitig der Halterung des wenigstens einen Speicherelements dient.A particularly compact and constructively advantageous configuration of the guide for the transfer element is achieved when the guide for the transfer element is arranged on a carrier element, with the carrier element simultaneously serving to hold the at least one storage element.

Zur möglichst flexiblen Verwendung des Trägerelements mit unterschiedlichen Magazinen bzw. Funktionselementen sieht es eine Weiterbildung des zuletzt gemachten Vorschlags vor, dass das wenigstens eine Speicherelement an dem Trägerelement austauschbar angeordnet ist.For the most flexible use of the carrier element with different magazines or functional elements, a development of the last proposal provides that the at least one storage element is arranged on the carrier element in an exchangeable manner.

Eine weitere konstruktive Anordnung bzw. Ausbildung der Bestückungseinrichtung, bei der ein unbeabsichtigtes Herausfallen eines Funktionselements aus dem Speicherelement vermieden wird, sieht vor, dass eine Abgabeseite des Speicherelements von dem Transferelement, außer in der Übernahmeposition, versperrt ist. Eine derartige Ausbildung ermöglicht es auch insbesondere bei nur einem Speicherelement ggf. auf ein separates Sperrelement für die Funktionselemente an dem Speicherelement zu verzichten.A further structural arrangement or design of the fitting device, in which a functional element is prevented from accidentally falling out of the storage element, provides that a delivery side of the storage element is blocked by the transfer element, except in the transfer position. Such training also makes it possible in particular if there is only one storage element, to dispense with a separate blocking element for the functional elements on the storage element.

Zum Vereinzeln von Funktionselementen aus den Speicherelementen ist es darüber hinaus bevorzugt vorgesehen, dass dem Speicherelement eine Sperrelement zum Freigeben eines Funktionselements in die Aufnahme des Transferelements zugeordnet ist.In order to separate functional elements from the storage elements, provision is also preferably made for the storage element to be assigned a blocking element for releasing a functional element into the receptacle of the transfer element.

Weiterhin betrifft die Erfindung ein Verfahren zum Verbinden eines Funktionselements mit einem Textil, insbesondere mittels einer erfindungsgemäßen Bestückungseinrichtung.Furthermore, the invention relates to a method for connecting a functional element to a textile, in particular by means of an assembly device according to the invention.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnungen.Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawings.

Gleiche Elemente bzw. Elemente mit gleicher Funktion sind in den Figuren mit den gleichen Bezugsziffern versehen.Identical elements or elements with the same function are provided with the same reference numbers in the figures.

In den Fig. 1 bis 4 sind jeweils paillettenartige Funktionselemente 1a bis 1d dargestellt, wie sie dazu vorgesehen sind, mit einem in den Fig. 4 bis 8 erkennbaren, vorzugsweise aus einem zumindest bereichsweise elektrisch leitenden Textil 100 mittels eines insbesondere elektrisch leitfähigen Fadens oder Garns 2 (Fig. 2, 8) verbunden zu werden. Die Funktionselemente 1a bis 1d weisen in Draufsicht unterschiedliche äußere Konturen 4a bis 4d auf, wobei die Kontur 4a quadratisch, die Kontur 4b dreiecksförmig, die Kontur 4c kreisrund und die Kontur 4d trapezförmig ausgebildet ist. Selbstverständlich sind auch andere Konturen denkbar.In the Figures 1 to 4 are each sequin-like functional elements 1a to 1d shown as intended, with a in the Figures 4 to 8 recognizable, preferably made of an at least partially electrically conductive textile 100 by means of an in particular electrically conductive thread or yarn 2 ( 2 , 8th ) to be connected. The functional elements 1a to 1d have different outer contours 4a to 4d in plan view, the contour 4a being square, the contour 4b triangular, the contour 4c circular and the contour 4d trapezoidal. Of course, other contours are also conceivable.

Die Funktionselemente 1a bis 1d bestehen beispielsweise aus einem Substrat 5 in Form einer Leiterplatte mit elektrisch leitfähigen Durchgangsbohrungen 3, über die die Funktionselemente 1a bis 1d mittels des Garns 2 mit dem Textil 100 verbindbar sind, wie dies in der Fig. 4 vereinfacht dargestellt ist. Die Verbindung zwischen dem Funktionselement 1a bis 1d und dem Textil 100 erfolgt durch Sticken, Nähen, Knüpfen oder ähnliche Verbindungstechniken mittels einer Nähmaschine 1000. Unter einer im Einzelnen nicht dargestellten Nähmaschine 1000 wird somit jegliche Maschine verstanden, die dazu vorgesehen ist, mittels des geeigneten Verbindungsverfahrens das Funktionselement 1a bis 1d mit dem Textil 100 zu verbinden.The functional elements 1a to 1d consist, for example, of a substrate 5 in the form of a printed circuit board with electrically conductive through-holes 3, via which the functional elements 1a to 1d can be connected to the textile 100 by means of the yarn 2, as is shown in FIG 4 is shown in simplified form. The connection between the functional element 1a to 1d and the textile 100 is made by embroidering, sewing, knotting or similar connection techniques using a sewing machine 1000. A sewing machine 1000, not shown in detail, is therefore understood to mean any machine that is intended for this purpose using the appropriate connection method to connect the functional element 1a to 1d to the textile 100.

Auf der Oberfläche des Substrats 5 sind beispielhaft mit den Durchgangsbohrungen 3 verbundene Leiterbahnen 6 sowie ein mit den Leiterbahnen 6 kontaktiertes elektronisches Bauteil 7, beispielsweise ein IC oder ähnliches, vorgesehen. Dies ist jedoch lediglich am Ausführungsbeispiel gemäß der Fig. 4 bei dem Funktionselement 1d dargestellt. Das Funktionselement 1a bis 1d ist - wie an sich bekannt - beispielsweise als Sensor, als Sendeeinrichtung oder ähnliches bzw. als Teil der genannten Elemente ausgebildet.On the surface of the substrate 5 , for example, conductor tracks 6 connected to the through-holes 3 and an electronic component 7 , which makes contact with the conductor tracks 6 , for example an IC or the like, are provided. However, this is only the embodiment according to 4 shown in the functional element 1d. The functional element 1a to 1d is--as is known--embodied, for example, as a sensor, as a transmitting device or the like, or as part of the elements mentioned.

Zur Zuführung des Funktionselements 1a bis 1d an eine Befestigungsstelle an dem Textil 100 dient eine in den Fig. 5 bis 9 dargestellte Bestückungseinrichtung 10. In der Fig. 5 ist erkennbar, dass die Bestückungseinrichtung 10 ein Trägerelement 12 aufweist, das im Wesentlichen schienen- oder plattenförmig ausgebildet ist. Das Trägerelement 12 weist mehrere Funktionen auf: Zum einen ist an der Oberseite des Trägerelements 12, d.h. auf der dem Textil 100 abgewandten Seite, mit dem Trägerelement 12 ein magazinartiges Speicherelement 14 austauschbar verbunden, das bei dem in den Fig. 5 bis 8 dargestellten Ausführungsbeispiel jeweils der Bevorratung von Funktionselementen 1a dient, die innerhalb des Speicherelements 14 übereinandergestapelt angeordnet sind.To feed the functional element 1a to 1d to a fastening point on the textile 100 is used in the Figures 5 to 9 assembly device shown 10. In the figure 5 it can be seen that the placement device 10 has a carrier element 12 which is essentially in the form of a rail or plate. The carrier element 12 has several functions: On the one hand, on the top side of the carrier element 12, ie on the side facing away from the textile 100, a magazine-like storage element 14 is interchangeably connected to the carrier element 12 Figures 5 to 8 illustrated embodiment serves to store functional elements 1a, which are arranged stacked on top of one another within storage element 14.

Im Bereich des Speicherelements 14 weist das Trägerelement 12 eine Durchgangsöffnung 16 zur Aufnahme des Speicherelements 14 auf. Weiterhin dient das Trägerelement 12 der Führung eines Transferelements 20 als Bestandteil einer Transfereinrichtung. Hierzu sind beispielsweise an dem Trägerelement 12 lediglich in der Fig. 5 erkennbare Führungselemente 21 oder ähnliches angeordnet, die eine Linearbewegung des Transferelements 20 in Richtung des Doppelpfeils 22 ermöglichen. Hierzu dient ein in den Figuren nicht dargestellter, weil an sich nicht erfindungswesentlicher Antrieb für das Transferelement 20.In the area of the storage element 14 , the carrier element 12 has a through-opening 16 for receiving the storage element 14 . Furthermore, the carrier element 12 serves to guide a transfer element 20 as part of a transfer device. For this purpose, for example, on the carrier element 12 only in the figure 5 recognizable guide elements 21 or the like arranged, which allow a linear movement of the transfer element 20 in the direction of the double arrow 22. A drive for the transfer element 20, which is not shown in the figures because it is not essential to the invention, is used for this purpose.

Wie anhand der Darstellung der Fig. 5 erkennbar ist, ist das Transferelement 20, das in Form einer Leiste 23 ausgebildet ist, unmittelbar oberhalb der Oberfläche des Textils 100 angeordnet. Weiterhin weist das Transferelement 20 bzw. die Leiste 23 eine Durchgangsöffnung 24 zur Ausbildung einer Aufnahme 30 für ein Funktionselement 1a auf. Die Durchgangsöffnung 24 hat eine Innenkontur 25, die der Außenkontur 4a bis 4d des jeweiligen Funktionselements 1a bis 1d angepasst ist. Die Dicke d der Leiste 23 entspricht der Höhe h des jeweiligen Funktionselements 1a bis 1d bzw. ist etwas größer als diese.As per the representation of figure 5 As can be seen, the transfer element 20, which is designed in the form of a strip 23, is arranged directly above the surface of the textile 100. Furthermore, the transfer element 20 or the strip 23 has a through opening 24 for forming a receptacle 30 for a functional element 1a. The through opening 24 has an inner contour 25 which is adapted to the outer contour 4a to 4d of the respective functional element 1a to 1d. The thickness d of the bar 23 corresponds to the height h of the respective functional element 1a to 1d or is slightly larger than this.

Weiterhin ist dem Speicherelement 14 auf einer dem Transferelement 20 zugewandten Abgabeseite 26 des Speicherelements 14 ein Sperrelement 28 zugeordnet, das in an sich bekannter Art und Weise dem Freigeben bzw. Sperren des jeweils untersten Funktionselements 1a bis 1d in dem Speicherelement 14 dient. Zuletzt wird erwähnt, dass das Trägerelement 12 zusammen mit dem Speicherelement 14 und dem Transferelement 20 senkrecht zur Richtung des Doppelpfeils 22 in Richtung des Doppelpfeils 29 mittels eines nicht gezeigten Antriebs höhenverstellbar angeordnet ist, derart, dass aus der in der Fig. 5 dargestellten Position, bei der sich das Transferelement 20 unmittelbar oberhalb der Oberfläche des Textils 100 befindet, das Transferelement 20 bzw. das Trägerelement 12 in einer Position anhebbar ist, in der das Funktionselement 1a bis 1d zum Verbinden des Funktionselements 1a bis 1d mittels des Garns 2 oder ähnlichem für einen Nähkopf oder ähnliches der Nähmaschine 1000 freigestellt bzw. zugänglich ist.Furthermore, the storage element 14 has a blocking element 28 on a delivery side 26 of the storage element 14 facing the transfer element 20 assigned, which is used in a manner known per se to enable or disable the respective lowermost functional element 1a to 1d in the memory element 14. Finally, it is mentioned that the carrier element 12 together with the storage element 14 and the transfer element 20 is arranged vertically adjustable in the direction of the double arrow 22 in the direction of the double arrow 29 by means of a drive, not shown, such that from the figure 5 shown position, in which the transfer element 20 is located directly above the surface of the textile 100, the transfer element 20 or the carrier element 12 can be raised in a position in which the functional element 1a to 1d is used to connect the functional element 1a to 1d by means of the yarn 2 or the like is released or accessible for a sewing head or the like of the sewing machine 1000 .

In den Fig. 6 bis 8 sind die wesentlichen Positionen bei der Verarbeitung von Funktionselementen 1a mittels der Bestückungseinrichtung 10 dargestellt. In der Fig. 6 ist erkennbar, dass die Aufnahme 30 des Transferelements 20 in einer Übernahmeposition unterhalb der Abgabeseite 26 des Speicherelements 14 in Ausrichtung mit dem Speicherelement 14 angeordnet ist. Weiterhin befindet sich bereits ein Funktionselement 1a in der Aufnahme 30. Anschließend wird entsprechend der Fig. 7 das Transferelement 20 linear in eine Übergabeposition zum Textil 100 verfahren, derart, dass sich das Funktionselement 1a unmittelbar oberhalb des Textils 100 an einer Soll-Position befindet. Dabei überdeckt das Speicherelement 14 die Abgabeseite 26 des Speicherelements 14 bzw. versperrt diese.In the Figures 6 to 8 the essential positions in the processing of functional elements 1a by means of the placement device 10 are shown. In the 6 it can be seen that the receptacle 30 of the transfer element 20 is arranged in a transfer position below the delivery side 26 of the storage element 14 in alignment with the storage element 14 . Furthermore, there is already a functional element 1a in the receptacle 30. Then, according to the 7 move the transfer element 20 linearly into a transfer position to the textile 100 in such a way that the functional element 1a is located directly above the textile 100 at a target position. In this case, the storage element 14 covers the delivery side 26 of the storage element 14 or blocks it.

Anschließend (nicht dargestellt) wird die Bestückungseinrichtung 10 bzw. das Transferelement 20 vertikal angehoben, um das Funktionselement 1a aus der Aufnahme 30 freizustellen. In der Fig. 8 ist der Zustand dargestellt, bei der anschließend das Transferelement 20 zusammen mit dem Trägerelement 12 in einer horizontal zurückversetzten sowie wieder auf das Textil 100 abgesenkten Position angeordnet ist. Weiterhin ist erkennbar, dass das Funktionselement 1a bereits mittels des Garns 2 mit dem Textil 100 verbunden wurde. Anschließend wiederholen sich die Vorgänge zur Bestückung des nächsten Textils 100 mit einem Funktionselement 1a wie beschrieben.Subsequently (not shown), the placement device 10 or the transfer element 20 is raised vertically in order to release the functional element 1a from the receptacle 30 . In the 8 the state is shown in which the transfer element 20 is then arranged together with the carrier element 12 in a horizontally set-back position and again lowered onto the textile 100. Furthermore, it can be seen that the functional element 1a has already been connected to the textile 100 by means of the yarn 2 . The processes for equipping the next textile 100 with a functional element 1a are then repeated as described.

Zuletzt ist in der Fig. 9 eine Bestückungseinrichtung dargestellt, bei der das Trägerelement 12a dazu ausgebildet ist, beispielhaft drei Speicherelemente 14a bis 14c aufzunehmen, wobei die Speicherelemente 14a bis 14c austauschbar an dem Trägerelement 12a angeordnet sind. Die Speicherelemente 14a bis 14c dienen jeweils entweder der Aufnahme gleicher Funktionselemente 1a bis 1d, oder aber, wie dargestellt, beispielhaft der Aufnahme von Funktionselementen 1a, 1b und 1c. Weiterhin ist erkennbar, dass das Transferelement 20a ebenfalls drei Aufnahmen 30a, 30b und 30c aufweist, deren (Innen-)Kontur 25a, 25b, 25c der Außenkontur 2a bis 2c der Funktionselemente 1a bis 1c angepasst ist. Zum Überführen der unterschiedlichen Funktionselemente 1a bis 1c mittels des Transferelements 20a wird die jeweilige Aufnahme 30a bis 30c in Überdeckung mit der jeweiligen Abgabeseite 26 des Speicherelements 14a bis 14c gebracht. Die soweit beschriebene Bestückungseinrichtung 10 kann in vielfältiger Art und Weise abgewandelt bzw. modifiziert werden, ohne vom in den Ansprüchen 1 bis 10 definierten Gegenstand abzuweichen.Last is in the 9 an assembly device is shown, in which the carrier element 12a is designed to accommodate, for example, three memory elements 14a to 14c, the memory elements 14a to 14c being arranged on the carrier element 12a in an exchangeable manner. The storage elements 14a to 14c each serve either to hold the same functional elements 1a to 1d or, as shown, to hold functional elements 1a, 1b and 1c, for example. It can also be seen that the transfer element 20a also has three receptacles 30a, 30b and 30c, the (inner) contour 25a, 25b, 25c of which is adapted to the outer contour 2a to 2c of the functional elements 1a to 1c. In order to transfer the different functional elements 1a to 1c by means of the transfer element 20a, the respective receptacle 30a to 30c is brought into overlap with the respective delivery side 26 of the storage element 14a to 14c. The mounting device 10 described so far can be modified in many ways without deviating from the subject matter defined in claims 1 to 10.
