Description

Verfahren und Anordnung zur Übermittlung garnspezifischer Method and arrangement for the transmission of yarn-specific
Daten bei Umspulvorgängen für die Herstellung von dokumentationspflichtigen DoppelsteppstichnähtenData during rewinding operations for the production of lockstitch seams that require documentation
Die Erfindung betrifft ein Verfahren zur Übermittlung garn- spezifisσher Daten bei Umspulvorgängen für die Herstellung von dokumentationspflichtigen Doppelsteppstichnähten sowie eine Anordnung zu seiner Durchführung.The invention relates to a method for the transmission of yarn-specific data during rewinding processes for the production of lockstitch seams requiring documentation and an arrangement for its implementation.
Im Rahmen zunehmender qualitätssichernder Maßnahmen in allen Bereichen der modernen Technik ist die Kenntnis der Fertigungsdaten bei der Herstellung eines Produktes unerläßlich. Bei der abschließenden Dokumentation des Herstellungsprozesses werden diese Daten zusammen mit Daten der am Produktionsprozeß beteiligten Komponenten in einem Datensatz zusammengefaßt, der dem jeweiligen Produkt zugeordnet wird und mittels einer Schlüsselnummer oder ähnlichem jederzeit abgefragt werden kann.As part of increasing quality assurance measures in all areas of modern technology, knowledge of the manufacturing data is indispensable when manufacturing a product. In the final documentation of the manufacturing process, this data is summarized together with data of the components involved in the production process in a data record which is assigned to the respective product and can be queried at any time by means of a key number or the like.
Im Zusammenhang mit der Fertigung von Reißnähten an Nähgutteilen muß dabei neben anderen Komponenten auch der Unterfaden bei Doppelsteppstichnähten dokumentiert werden. Da die Unterfadenspule für den Herstellungsprozeß der Doppel steppstichnaht einerseits unerläßlich ist, andererseits ihr Fassungsvermögen aber stark begrenzt ist, dient sie nur als Zwischenträger für das Unterfadengarn.In connection with the production of tear seams on sewing material parts, the lower thread for double lockstitch seams must be documented in addition to other components. Because the bobbin for the manufacturing process of the double lockstitch is indispensable on the one hand, but on the other hand its capacity is very limited, it only serves as an intermediate carrier for the bobbin thread.
Daraus ergibt sich das Problem, daß die das Garn für die Bildung des Unterfadens betreffenden Informationen, wie beispielsweise Artikel- oder Chargennummer während des Spulvorganges nicht auf die Unterfadenspule übertragen werden können. Ist die Unterfadenspule bespult und der herkömmlichen Spulstation entnommen, besteht somit keine Möglichkeit mehr, den aufgespulten Faden zu identifizieren und Detailinformationen über ihn zu speichern. Somit besteht auch keine Möglichkeit, den als Reißfaden ausgelegten Unterfaden in der Dokumentation zu berücksichtigen.This results in the problem that the information relating to the yarn for the formation of the lower thread, such as, for example, article or batch number, cannot be transferred to the lower thread bobbin during the winding process. Once the bobbin has been wound and removed from the conventional winding station, there is no longer any possibility of identifying the wound thread and storing detailed information about it. There is therefore no possibility of taking the bobbin thread, which is designed as a tear thread, into account in the documentation.
Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung des vorstehend genannten Nachteils eine lückenlose Dokumentation der den Unterfaden in Doppelsteppstichnähten betreffenden Daten im Zusammenhang mit anderen Daten über den Herstellungsprozeß eines genähten Produktes zu ermöglichen.The object of the invention is to enable complete documentation of the data relating to the lower thread in lockstitch seams in connection with other data about the manufacturing process of a sewn product while avoiding the disadvantage mentioned above.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die den Faden aufnehmende Spule, insbesondere Unterfadenspule mit einer eindeutigen Spulenkennung versehen wird, daß in einer Spulstation, in der Garn für den Unterfaden von einem Garnvorrat auf die Unterfadenspule aufgespult wird, die Spulenkennung erfaßt, und zusammen mit einem das Garn und den Spulvorgang kennzeichnenden ersten Datensatz in einem Datenspeicher gespeichert werden, daß nach dem Einsetzen der Unterfadenspule in eine Nähmaschine die Spulenkennung erfaßt wird, daß anhand der Spulenkennung der zusammen mit dieser gespeicherte erste Datensatz ermittelt und einem den Nähvorgang und/oder das Nähgut betreffenden zweiten Datensatz zugeordnet wird und daß die so gebildete Datenmenge gespeichert wird.This object is achieved in that the bobbin receiving the thread, in particular the bobbin is provided with a unique bobbin identifier, that in a bobbin station in which the yarn for the bobbin thread is spooled from a yarn supply onto the bobbin, the bobbin identifier is recorded, and together with a first data set characterizing the yarn and the winding process are stored in a data memory, so that after the lower thread bobbin is inserted into a sewing machine, the bobbin identification is detected, that the first data set stored together with this is determined on the basis of the bobbin identification number and the sewing process and / or the material to be sewn is assigned to the relevant second data record and that the amount of data thus formed is stored.
Durch die eindeutige Kennzeichnung der Unterfadenspulen ist es möglich, eine bestimmte Garnlänge des eindeutig gekenn- zeichneten Garnvorrates einer bestimmten Naht eines Produktes zuzuordnen und damit die Garndaten des Unterfadens in einem die Herstellung eines Produktes kennzeichnenden Datensatz zu erhalten. Die Spulenkennung spielt für den endgültigen Datensatz keine Rolle. Sie dient lediglich dazu, die Verbindung zwischen dem ersten Datensatz und dem zweiten Datensatz herzustellen.The clear identification of the bobbin makes it possible to determine a specific length of yarn of the clearly to assign the drawn yarn supply to a specific seam of a product and thus to obtain the yarn data of the lower thread in a data record which characterizes the manufacture of a product. The coil identifier is irrelevant for the final data set. It only serves to establish the connection between the first data record and the second data record.
Um die Unterfadenspulen immer wieder verwenden zu können, wird erfindungsgemäß die Zuordnung des ersten Datensatzes zur Spulenkennung nach dem Verbrauch des Unterfadens und dem Entfernen eines eventuellen Restfadens von der jeweiligen Unterfadenspule in der Spulstation gelöscht, bevor ein neuer Faden auf die Unterfadenspule aufgespult wird.In order to be able to use the lower thread bobbins again and again, the assignment of the first data record to the bobbin identification after the consumption of the lower thread and the removal of any residual thread from the respective lower thread bobbin in the winding station is deleted before a new thread is wound onto the lower thread bobbin.
Die Erfindung betrifft ferner eine Anordnung zur Übermittlung garnspezifischer Daten bei Umspulvorgängen für die Herstellung von dokumentationspflichtigen Doppelsteppstichnähten in Doppelsteppstichmaschinen mit mindestens einer Nähmaschine und einer Spulstation, in der Garn für den Unterfaden von einem Garnvorrat auf in die Nähmaschine einzusetzende Unterfadenspule gespult wird. Diese Anordnung ist erfindungsgemäß dadurch gekennzeichnet, daß die Unterfadenspulen jeweils mit einer eindeutigen Spulenkennung versehen sind, daß die Spulstation und die Nähmaschine jeweils einen Sensor zum Erfassen der Spulenkennung der jeweils eingesetzten Unterfadenspule haben und daß die Sensoren mit einer Datenverarbeitungseinrichtung verbunden sind, welche die von dem Sensor der Spulstation erfaßte Spulenkennung einem den Unterfaden und den Spulvorgang kennzeichnenden ersten Datensatz zuordnet und zusammen mit diesem in einem Datenspeicher speichert und welche anhand der von dem Sensor der Nähmaschine erfaßten Spulenkennung den zugehörigen ersten Datensatz ermittelt, einem den Nähvorgang und/oder das Nähgut kennzeichnenden zweiten Datensatz zuordnet und zusammen mit diesem speichert. Bei einer bevorzugten Ausführungsform der Erfindung ist die Spulenkennung in Form eines Barcodes auf mindestens einem der Flansche der Unterfadenspule aufgebracht, wobei die Sensoren in der Spulstation und der Nähmaschine Barcode-Leser sind.The invention further relates to an arrangement for the transmission of yarn-specific data during rewinding operations for the production of lockstitch seams that require documentation in lockstitch machines with at least one sewing machine and a winding station in which yarn for the lower thread is wound from a thread supply onto the lower thread bobbin to be inserted into the sewing machine. This arrangement is characterized in that the lower thread bobbins are each provided with a unique bobbin identifier, that the bobbin station and the sewing machine each have a sensor for detecting the bobbin identifier of the bobbin thread used in each case, and that the sensors are connected to a data processing device which by the Sensor of the bobbin station detects a bobbin identifier assigned to a first data set which characterizes the bobbin thread and the bobbin winding process and stores it together with this in a data memory and which uses the bobbin identifier acquired by the sensor of the sewing machine to determine the associated first data set, a second characterizing the sewing process and / or the material to be sewn Assigns data record and saves it together with it. In a preferred embodiment of the invention, the coil identification is in the form of a bar code on at least one of the Flanges of the bobbin are applied, the sensors in the winding station and the sewing machine are barcode readers.
Das erfindungsgemäße Verfahren ist nicht auf das Umspulen eines Fadens auf die Unterfadenspule einer Doppelsteppstichmaschine beschränkt, sondern für alle Umspulvorgänge verwendbar.The method according to the invention is not limited to the rewinding of a thread onto the lower thread spool of a lockstitch machine, but can be used for all rewinding operations.
Die folgende Beschreibung erläutert in Verbindung mit der beigefügten Zeichnung die Erfindung anhand eines Ausführungsbeispiels. Es zeigen:The following description in conjunction with the accompanying drawings explains the invention using an exemplary embodiment. Show it:

Fig. 1 zeigt eine zum Einsetzen in eine Doppelsteppstichnähmaschine bestimmte Unterfadenspule 10, die auf der Außenseite ihres einen Flansches 12 ein Feld 14 hat, auf dem eine die jeweilige Unterfadenspule 10 eindeutig kennzeichnende Identitätsnummer 16 in Form eines Barcodes aufgedruckt ist. Es kann selbstverständlich auch eine andere maschinenlesbare Form der Codierung gewählt werden.1 shows a bobbin 10 intended for insertion into a lockstitch sewing machine, which has a field 14 on the outside of its one flange 12, on which an identity number 16 which uniquely identifies the respective bobbin 10 is printed in the form of a barcode. Another machine-readable form of coding can of course also be selected.
Fig. 2 zeigt eine Mehrzahl von schematisch dargestellten Doppelsteppstichnähmaschinen 18, die jeweils über einen PC 20 gesteuert werden. Über eine Daten- und Steuerleitung 22 stehen die PC's der einzelnen Nähstationen mit einer zentralen Datenverarbeitungseinrichtung 24 in Verbindung. Ferner sind die PC's der einzelnen Nähstationen und/oder die Datenverar- beitungseinrichtung 24 über eine Leitung 25 mit einem PC 26 verbunden, der eine Spulstation 28 steuert. Unter der Leitung 25 ist jedes Mittel zu verstehen, das einen Informationsfluß zwischen dem PC 26 und der Datenverarbeitungseinrichtung 24 ermöglicht.2 shows a plurality of schematically illustrated lockstitch sewing machines 18, which are each controlled by a PC 20. The PCs of the individual sewing stations are connected to a central data processing device 24 via a data and control line 22. Furthermore, the PCs of the individual sewing stations and / or the data processing beitungseinrichtung 24 connected via a line 25 to a PC 26 which controls a winding station 28. The line 25 is to be understood as any means that enable information to flow between the PC 26 and the data processing device 24.
Die Spulstation 28 dient dazu, einen zur Bildung eines Unterfadens bestimmten Garnabschnitt von einer Garnkone 30 auf eine Unterfadenspule 10 aufzuspulen. Die Spulstation 28 hat einen ersten schematisch dargestellten Sensor oder Barcode- Leser 31 zum Lesen eines an der Garnkone 30 vorgesehenen Barcodes und einen schematisch dargestellten zweiten Sensor oder Barcode-Leser 32, der in der Lage ist, den Barcode 16 auf dem Flansch 12 der in der Spulstation 28 eingesetzten Unterfadenspule 10 zu lesen. Die so erfaßte Identitätsnummer der gerade in die Spulstation 28 eingesetzten Unterfadenspule 10 wird im PC 26 oder der Datenverarbeitungseinrichtung 24 einem ersten Datensatz zugeordnet, der die Garnkone 30 (beispielsweise Artikel- und Chargennummer) kennzeichnet und in den PC 26 eingegeben oder automatisch mittels des Sensors 31 in der Spulstation erfaßt wurde. Ferner umfaßt der erste Datensatz Daten über den Spulvorgang wie Datum des Spulvorganges und Länge des aufgespulten Fadens. Der erste Datensatz wird zusammen mit der Identitätsnummer der Unterfadenspule 10 in der Datenverarbeitungseinrichtung 24 gespeichert. Damit ist der auf einer bestimmten Unterfadenspule zwischengespeicherte Unterfadenvorrat eindeutig identifiziert.The winding station 28 serves to wind a section of yarn intended to form a lower thread from a thread cone 30 onto a lower thread bobbin 10. The winding station 28 has a first schematically illustrated sensor or barcode reader 31 for reading a barcode provided on the yarn cone 30 and a schematically illustrated second sensor or barcode reader 32 which is capable of reading the barcode 16 on the flange 12 of FIG the bobbin 10 used to read the bobbin station 28. The identity number of the lower thread bobbin 10 just inserted into the winding station 28 is assigned in the PC 26 or the data processing device 24 to a first data record which identifies the yarn cone 30 (for example article and batch number) and is entered into the PC 26 or automatically by means of the sensor 31 was recorded in the winding station. The first data record also includes data about the winding process, such as the date of the winding process and the length of the thread being wound. The first data record is stored together with the identity number of the bobbin 10 in the data processing device 24. The bobbin thread store temporarily stored on a specific bobbin is thus clearly identified.
Die Doppelsteppstichnähmaschinen 18 haben ebenfalls einen Sensor oder Barcode-Leser 34, welcher die Identitätsnummer 16 auf dem Spulenflansch 12 der jeweiligen eingesetzten Unterfadenspule 10 lesen kann. Die so ermittelte Identitätsnummer der Unterfadenspule 10 wird der Datenverarbeitungseinrichtung 24 zusammen mit einem über den Nähvorgang und/oder das Nähgut enthaltenden zweiten Datensatz übermittelt. Die Datenverarbeitungseinrichtung 24 kann anhand der übermittelten Spulenkennung 16 den bereits abgespeicherten ersten Datensatz mit dem von der Nähmaschine übermittelten zweiten Datensatz zusammenführen, so daß der gesamte Datensatz nun auch die den Unterfaden kennzeichnenden Daten enthält. Damit ist die Aufgabe der Spulenkennung erfüllt. Sie fällt aus dem Datensatz heraus. Die Unterfadenspule kann wieder neu verwendet werden.The lockstitch sewing machines 18 also have a sensor or barcode reader 34, which can read the identity number 16 on the bobbin flange 12 of the respective bobbin 10 used. The identity number of the lower thread bobbin 10 determined in this way is transmitted to the data processing device 24 together with a second data record containing the sewing process and / or the sewing material. The data processing device 24 can be based on the transmitted Bobbin identifier 16 merge the already stored first data record with the second data record transmitted by the sewing machine, so that the entire data record now also contains the data identifying the bobbin thread. The coil identification task is thus accomplished. It falls out of the data set. The bobbin can be used again.
Es versteht sich, daß gewährleistet werden muß, daß jede Unterfadenspulen-Identitätsnummer jeweils nur einmal vergeben wird. Die Existenz von Barcode-Dubletten muß zwingend ausgeschlossen werden.It is understood that it must be ensured that each bobbin bobbin identity number is only assigned once. The existence of duplicate barcodes must be ruled out.
Man kann durch Änderungen an der Unterfadenspule und an dem Aufsteckmechanismus für die Unterfadenspulen an der Spulstation sicherstellen, daß die erfindungsgemäßen Unterfadenspulen nicht an einem herkömmlichen Spulapparat bespult werden können. Durch zusätzliche farbliche Markierungen und Hinweisschilder an den entsprechenden Nutzungsorten kann das Bedienungspersonal auf die besondere Funktion der erfindungsgemäßen Unterfadenspulen hingewiesen werden.It can be ensured by changes to the lower thread bobbin and to the plug-on mechanism for the lower thread bobbins at the winding station that the lower thread bobbins according to the invention cannot be wound on a conventional winder. Additional colored markings and signs at the appropriate places of use can be used to draw the attention of the operating personnel to the special function of the bobbin under the invention.
Die Figuren 3a und 3b zeigen die Verfahrensschritte beim Erstellen der Zuordnung zwischen dem ersten Datensatz und der Unterfadenspulenkennung an der Spulstation 28, bzw. beim Auslesen der Zuordnung an der jeweiligen Nähmaschine 18. In beide Verfahrensabläufe ist jeweils ein Prüfschritt eingebaut, nachdem das Verfahren abgebrochen werden kann. An der Spulstation 28 wird geprüft, ob die aufgesetzte Garnkone 30 für den Verbrauch freigegeben wurde. Das Garn wird vor dem Umspulvorgang auf die geforderte Qualität hin überprüft. Sind die Prüfkriterien erfüllt, wird dies auf der Garnkone 30 vermerkt und von dem Barcode-Leser 31 in der Spulstation 28 erfaßt. Fehlt ein solcher positiver Prüfvermerk, wird der Umspulvorgang nicht gestartet.FIGS. 3a and 3b show the method steps when creating the association between the first data set and the lower thread bobbin identifier at the winding station 28, or when reading out the association on the respective sewing machine 18. A test step is built into both method sequences after the method has been terminated can. At the winding station 28 it is checked whether the attached thread cone 30 has been released for consumption. The yarn is checked for the required quality before the rewinding process. If the test criteria are met, this is noted on the yarn cone 30 and detected by the barcode reader 31 in the winding station 28. If such a positive test note is missing, the rewinding process is not started.
In Fig. 3b wird geprüft, ob der Faden auf der eingesetzten Unterfadenspule für die jeweilige Nähaufgabe geeignet ist. Auch hier wird der Nähvorgang nicht gestartet, wenn diese Prüfung negativ ausfällt. In Fig. 3b it is checked whether the thread on the lower thread spool used is suitable for the respective sewing task. Here, too, the sewing process is not started if this test is negative.
