Description

Die Erfindung betrifft eine Nähanlage mit einer Nähmaschine und mit einer Nähgut-Nähtransporteinrichtung zum Transportieren von Nähgut von einem Zuführ-Bereich hin zu einem Stichbildungsbereich und vom Stichbildungsbereich hin zu einem Ablege-Bereich.The invention relates to a sewing machine with a sewing machine and with a sewing material-transporting device for transporting sewing material from a feed area towards a stitch formation area and from the stitch formation area to a laying area.

Eine derartige Nähanlage ist durch offenkundige Vorbenutzung der Klasse 911-210 der Dürkopp Adler AG bekannt. Die DE 10 2007 001 666 A1 offenbart eine Nähanlage mit einer ersten Transporteinheit zur Verlagerung von Nähgutteilen von einer Vorbereitungsstation hin zu einer Nähstation und mit einer zweiten Transporteinheit zur Verlagerung der Nähgutteile von der Nähstation hin zu einer Ablagestation. Die DE 10 2009 038 602 A1 offenbart eine Nähanlage mit einem ersten Roboter zur Entnahme jeweils eines Obermaterialteils und eines Untermaterialteils und zum Transport hin zu einer Einlegestation und Anordnung in einem Nähguthalter und mit einem zweiten Roboter zur Entnahme eines Nähguthalters aus der Einlegestation und zur Zuführung des Nähguthalters hin zu einer ersten Nähstation. Im Betrieb erfordert diese Nähanlage eine Mehrzahl von Nähguthaltern.Such a sewing unit is known by public prior use of class 911-210 Dürkopp Adler AG. The DE 10 2007 001 666 A1 discloses a sewing unit with a first transport unit for moving workpieces from a preparation station to a sewing station and with a second transport unit for moving the workpieces from the sewing station to a storage station. The DE 10 2009 038 602 A1 discloses a sewing machine with a first robot for removing respectively an upper part and a lower material part and for transport to an insertion station and arrangement in a workpiece holder and with a second robot for removing a workpiece holder from the insertion station and for feeding the Nähguthalters towards a first sewing station. In operation, this sewing unit requires a plurality of material holders.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Nähanlage der eingangs genannten Art derart weiterzubilden, dass eine Effizienz des Nähprozesses erhöht ist.It is an object of the present invention to further develop a sewing unit of the type mentioned in the introduction such that an efficiency of the sewing process is increased.

Diese Aufgabe ist erfindungsgemäß gelöst durch eine Nähanlage mit den im Anspruch 1 angegebenen Merkmalen.This object is achieved by a sewing unit with the features specified in claim 1.

Erfindungsgemäß wurde erkannt, dass es möglich ist, mit genau einem einzigen, nähgutspezifischen Halterahmen zu arbeiten und gleichzeitig einen zeitlichen Überlapp zwischen Nähtransport und Versorgungstransport des Nähguts herbeizuführen. Es ist nicht erforderlich, dass bei Benutzung genau eines Halterahmens die Bedienperson wartet, bis der gesamte Nähprozess abgearbeitet ist, und dann manuell diesen Halterahmen mit neuem Nähgut bestückt. Aufgrund des erfindungsgemäßen zeitlichen Überlapps ist somit die zeitliche Effizienz des Nähprozesses erhöht. Zudem benötigt die erfindungsgemäße Nähanlage keine Mehrzahl von nähgutspezifischen Halterahmen, was die Rüstkosten der Nähanlage vermindert. Es kann während des gesamten Nähprozesses mit genau einem Halterahmen gearbeitet werden.According to the invention, it has been recognized that it is possible to work with exactly one single, property-specific holding frame and at the same time bring about a temporal overlap between the sewing transport and the supply transport of the sewing material. It is not necessary that when using exactly one holding frame, the operator waits until the entire sewing process is completed, and then manually equipped this holding frame with new material. Due to the temporal overlap according to the invention thus the temporal efficiency of the sewing process is increased. In addition, the sewing unit according to the invention does not require a plurality of material-specific holding frames, which reduces the setup costs of the sewing unit. It can be worked with exactly one holding frame during the entire sewing process.

Ein Greifroboter nach Anspruch 2 lässt sich flexibel an die Erfordernisse verschiedener Nähguttypen anpassen.A gripper robot according to claim 2 can be flexibly adapted to the requirements of different types of sewing material.

Ein Greifroboter nach Anspruch 3 vereint elegant die Versorgungstransportfunktion zum Zuführen des Nähguts mit derjenigen zum Abführen des Nähguts.A gripper robot according to claim 3 elegantly combines the supply transport function for feeding the material with that for discharging the material.

Bei einer Nähanlage nach Anspruch 4 findet ein zeitlicher Überlapp beim Nähgut-Transport einerseits zwischen einem Zuführ-Versorgungstransportbereich und einem Nähtransport-Bereich und andererseits zwischen dem Nähtransport-Bereich und einem Ablege-Versorgungstransportbereich statt. Die zeitliche Effizienz beim Abarbeiten des Nähprozesses ist somit nochmals erhöht.In a sewing unit according to claim 4, there is a temporal overlap in the material transport on the one hand between a feed supply transport area and a Nähtransport area and on the other hand between the Nähtransport area and a deposit supply transport area. The time efficiency when processing the sewing process is thus increased again.

Ein vollautomatischer Nähprozess nach Anspruch 5 ist besonders effizient.A fully automatic sewing process according to claim 5 is particularly efficient.

Ein Ausführungsbeispiel wird nachfolgend anhand der Zeichnung näher erläutert. Die einzige Fig. zeigt schematisch eine Nähanlage 1 einer Ansicht von oben, wobei hauptsächlich die verschiedenen Nähgut-Arbeitsbereiche bei der Verarbeitung durch die Nähanlage 1 dargestellt sind.An embodiment will be explained in more detail with reference to the drawing. The single FIGURE schematically shows a sewing unit 1 of a view from above, wherein mainly the different work fabric work areas are shown during processing by the sewing unit 1.

Die Nähanlage 1 hat eine Nähmaschine 2 zum Vernähen zweier Nähgutteile. Dies ist in der Fig. am Beispiel einer Manschette 3 gezeigt. Die Nähmaschine 2 vernäht das Nähgut 3 in einem Stichbildungsbereich 4 durch Ausbilden mindestens einer Naht 5. Zum Transportieren des Nähguts 3 von einem Zuführ-Bereich 6 hin zum Stichbildungsbereich 4 und zum Transportieren des Nähguts 3 vom Stichbildungsbereich 4 hin zu einem Ablege-Bereich 7 dient eine Nähgut-Nähtransporteinrichtung 8. Letztere hat genau einen Halterahmen 9, dessen Randkontur auf eine Kontur der auszubildenden Naht 5 abgestimmt ist. Der Halterahmen 9 ist geführt gehalten von einer Linearführung 10 der Nähgut-Transporteinrichtung 8. Die Linearführung 10 erstreckt sich zwischen dem Zuführ-Bereich 6 über den Stichbildungsbereich 4 bis hin zum Ablege-Bereich 7. Diese drei Bereiche 4, 6 und 7 stellen einen Nähtransport-Bereich 11 dar.The sewing unit 1 has a sewing machine 2 for sewing two Nähgutteile. This is shown in the figure using the example of a sleeve 3. The sewing machine 2 sews the fabric 3 in a stitch formation region 4 by forming at least one seam 5. For transporting the fabric 3 from a supply region 6 toward the stitch formation region 4 and for transporting the fabric 3 from the stitch formation region 4 toward a deposition region 7 a Nähgut-Nähtransporteinrichtung 8. The latter has exactly one holding frame 9, the edge contour is tuned to a contour of the seam 5 to be formed. The support frame 9 is held guided by a linear guide 10 of the fabric transport device 8. The linear guide 10 extends between the feed area 6 on the stitch formation area 4 to the depositing area 7. These three areas 4, 6 and 7 provide a Nähtransport Area 11

Zum Bewegen des Halterahmens 9 zwischen dem Zuführbereich 6 (vgl. die Momentanstellung der Fig.) und dem Ablege-Bereich 7 dient ein Nähtransport-Antrieb 12. Letzterer beinhaltet einen in an sich bekannter Weise ausgeführten, gesteuert antreibbaren x-y-Koordinatentisch zur Erzeugung der Kontur der Naht 5 beim Nähen.For moving the holding frame 9 between the feed area 6 (see the instantaneous position of Fig.) And the storage area 7 is a Nähtransport drive 12. The latter includes a running in a known manner, controlled drivable xy-coordinate table for generating the contour the seam 5 when sewing.

Die Nähanlage 1 hat weiterhin eine Nähtgut-Versorgungstransporteinrichtung 13. Letztere dient zum Transportieren des Nähguts 3 von einem Nähgut-Zuführ-Stapelbereich 14 hin zum Zuführ-Bereich 6 der Nähgut-Nähtransporteinrichtung 8 sowie zum Transportieren des Nähguts 3 vom Ablege-Bereich 7 der Nähgut-Nähtransporteinrichtung 8 hin zu einem Nähgut-Ablege-Stapelbereich 15. Die Nähgut-Versorgungstransporteinrichtung 13 transportiert das Nähgut 3 also einerseits in einem Zuführ-Versorgungstransportbereich 16 und in einem Ablege-Versorgungstransportbereich 17. Der Zuführ-Versorgungstransportbereich 16 beinhaltet den Nähgut-Zuführ-Stapelbereich 14 und den Zuführ-Bereich 6. Der Ablege-Versorgungs-Transportbereich 17 beinhaltet den Ablege-Bereich 7 und den Nähgut-Ablege-Stapelbereich 15.The sewing unit 1 further has a Nähtgut supply transport device 13. The latter is used to transport the material 3 from a material feed stacking area 14 to the feed area 6 of the Nähgut-transporting 8 and for transporting the material 3 from Laying area 7 of the sewing material-transporting device 8 toward a fabric-depositing-stacking area 15. The fabric supply transport device 13 thus transports the material 3 on the one hand in a feed supply transport area 16 and in a deposit supply transport area 17. The feed supply transport area 16 includes the cloth feeding pile portion 14 and the feeding portion 6. The laying feed conveying portion 17 includes the laying portion 7 and the cloth laying pile portion 15.

Die Nähgut-Versorgungstransporteinrichtung 13 ist als Greifroboter ausgebildet und beinhaltet eine Roboter-Basiseinheit 18, die über eine Gelenkverbindung 19 mit einem Nähgutgreifer 20 verbunden ist und diesen ansteuert. Beim dargestellten Ausführungsbeispiel ist ein und derselbe Greifroboter 13 einerseits zum Transportieren des Nähguts 3 innerhalb des Zuführ-Versorgungstransportbereichs 16 und andererseits innerhalb des Ablege-Versorgungstransportbereichs 17 ausgebildet.The fabric supply transport device 13 is designed as a gripper robot and includes a robot base unit 18 which is connected via a hinge connection 19 with a Nähgutgreifer 20 and controls it. In the illustrated embodiment, one and the same gripper robot 13 is formed, on the one hand, for transporting the material 3 within the feed supply transport region 16 and, on the other hand, within the depositing supply transport region 17.

Die Nähgut-Nähtransporteinrichtung 8 einerseits und die Nähgut-Versorgungstransporteinrichtung 13 andererseits sind so ausgebildet, dass sie im Betrieb der Nähanlage 1 das Nähgut 3 zeitlich überlappend transportieren. Hierbei findet im Betrieb der Nähanlage 1 ein zeitlicher Überlapp sowohl beim Transportieren des Nähguts 3 in Zuführ-Versorgungstransportbereich 16 als auch beim Transportieren des Nähguts 3 im Ablege-Versorgungstransportbereich 17 mit dem Transportieren des Nähguts 3 innerhalb des Nähtransport-Bereichs 11 statt. Die Nähanlage 1 ist dabei so ausgelegt, dass ein Nähprozess vom Transportieren des Nähguts 3 vom Nähgut-Zuführ-Stapelbereich 14 hin zum Zuführ-Bereich 6 der Nähgut-Nähtransporteinrichtung 8 bis zum Transportieren des Nähguts 3 vom Ablege-Bereich 7 der Nähgut-Nähtransporteinrichtung 8 bis hin zum Nähgut-Ablege-Stapelbereich 15 automatisch erfolgt.On the other hand, the sewing material transporting device 8 on the one hand and the sewing material supply transporting device 13 on the other hand are designed such that they transport the sewing material 3 overlapping in time during operation of the sewing unit 1. Here, during operation of the sewing unit 1, a temporal overlap takes place both during transport of the material 3 in the supply supply transport area 16 and during transport of the material 3 in the deposit supply area 17 with the transport of the material 3 within the transport area 11. The sewing unit 1 is designed so that a sewing process from the transporting of the material 3 from the material feed stacking area 14 to the feed area 6 of the sewing material transporting device 8 to transport the material 3 from the storage area 7 of the sewing material-Nähtransporteinrichtung 8 up to the fabric-depositing stack area 15 is done automatically.

Nachfolgend wird der Nähprozess beispielhaft erläutert: Zur Vorbereitung des Nähprozesses wird ein Stapel des Nähguts 3, also ein Stapel Manschetten, im Nähgut-Zuführ-Stapelbereich 14 angeordnet. Der Greifroboter 13 wird so angesteuert, dass der Nähgutgreifer 20 die oberste Manschette 3 dieses Stapels im Nähgut-Zuführ-Stapelbereich 14 ergreift und hin zum Zuführ-Bereich 6 der Nähgut-Nähtransporteinrichtung 8 überführt (vgl. Richtungspfeil 21). Anschließend wird die Manschette 3 vom Halterahmen 9 der Nähgut-Nähtransporteinrichtung 8 erfasst und das Nähgut bzw. die Manschette 3 wird mit dem Halterahmen 9 hin zum Stichbildungsbereich 4 überführt, wo durch synchronisierte x-y-Ansteuerung des Nähtransportantriebs 12 die gewünschte Kontur der Naht 5 durch die Nähmaschine 2 im Stichbildungsbereich 4 erzeugt wird. Anschließend wird das Nähgut 3 mit dem Halterahmen 9 mittels der Nähgut-Nähtransporteinrichtung 8 hin zum Ablege-Bereich 7 überführt. Während des Nähens im Stichbildungsbereich 4 kann der Greifroboter 13 die nächste Manschette 3 vom Nähgutstapel im Nähgut-Zuführ-Stapelbereich 14 hin zum Zuführ-Bereich 6 der Nähgut-Nähtransporteinrichtung 8 überführen. Nach dem Ablegen des Nähguts 3 im Ablege-Bereich 7 fährt der Halterahmen 9 zurück zum Zuführ-Bereich 6 und erfasst dort die nächste Manschette 3, so dass der Nähvorgang für das nächste Stück Nähgut 3 zur Erzeugung der Naht 5 folgen kann. Während der Halterahmen 9 diese nächste Manschette 3 im Zuführ-Bereich 6 erfasst, kann der Greifroboter 13 zeitlich überlappend die fertig genähte Manschette 3 vom Ablege-Bereich 7 hin zum Nähgut-Ablege-Stapelbereich 15 überführen, wobei die fertig genähte Manschette 3 wiederum vom Nähgutgreifer 20 erfasst wird (vgl. Richtungspfeil 22). Die vorstehend geschilderten, zeitlich überlappenden Vorgänge finden so lange statt, bis der gesamte Stapel Nähgut 3 verarbeitet wurde und fertig genäht im Nähgut-Ablege-Stapelbereich 15 gestapelt vorliegt. Dieser ganze Vorgang findet vollautomatisch statt.In the following, the sewing process is explained by way of example: To prepare the sewing process, a stack of the material 3, that is to say a stack of sleeves, is arranged in the material feed stack area 14. The gripping robot 13 is activated such that the material gripper 20 grips the topmost sleeve 3 of this stack in the material feed stacking area 14 and transfers it to the feed area 6 of the material handling device 8 (see directional arrow 21). Subsequently, the cuff 3 is detected by the holding frame 9 of the sewing material-transporting device 8 and the sewing material or the cuff 3 is transferred to the holding frame 9 towards stitch formation area 4, where by synchronized xy-driving the Nähtransportantriebs 12 the desired contour of the seam 5 through the Sewing machine 2 in the stitching area 4 is generated. Subsequently, the sewing material 3 is transferred to the holding frame 9 by means of the sewing material-Nähtransporteinrichtung 8 towards the deposit area 7. During sewing in the stitch formation area 4, the gripper robot 13 can transfer the next cuff 3 from the fabric stack in the fabric feed stack area 14 to the feed area 6 of the fabric sewing transport 8. After placing the material 3 in the storage area 7 of the holding frame 9 moves back to the feed area 6 and detects there the next cuff 3, so that the sewing process for the next piece of fabric 3 to produce the seam 5 can follow. While the holding frame 9 detects this next cuff 3 in the feed area 6, the gripping robot 13 can overlap the finished sewn cuff 3 from the depositing area 7 to the fabric depositing stack area 15 in overlapping time, with the finished sewn cuff 3 in turn coming from the material gripper 20 is detected (see directional arrow 22). The above-described, temporally overlapping processes take so long instead of until the entire stack of sewing material 3 has been processed and finished sewn in the fabric storage stacking area 15 is present stacked. This whole process takes place fully automatically.
