Description

Die vorliegende Erfindung betrifft eine Hilfsvorrichtung an einer Nähmaschine zur Sicherung gegen das Anbringen eines einer bestimmten Maschineneinstellung nicht zugeordneten, auswechselbaren Nähfußes. Im allgemeinen sind Nähfüße einer Nähmaschine austauschbar an einem Schaft oder direkt an der Stoffdrückerstange der Maschine befestigt. Diese Nähfüße sind Zubehörteile, welche zur Ausführung bestimmter Näharbeiten benötigt werden und entsprechend gestaltet sind. Je nach Art und Ausstattung der Nähmaschine variiert die Anzahl der beigeordneten Nähfüße und es ist oft recht schwierig, die verschiedenen Füße voneinander zu unterscheiden. Es sind daher verschiedene Vorkehrungen bekanntgeworden, um die Unterscheidung zu erleichtern, wie Ziffern, Zeichen, Farbcodes und dergleichen. Wenn jedoch die Bedienungsperson trotzdem einen falschen Nähfuß an der Maschine anbringt, sind keine Vorkehrungen getroffen, um sie auf diesen Umstand aufmerksam zu machen.The present invention relates to an auxiliary device on a sewing machine for securing against the attachment of a replaceable presser foot that is not assigned to a specific machine setting. In general, presser feet of a sewing machine are interchangeably attached to a shaft or directly to the presser bar of the machine. These sewing feet are accessories that are required to carry out certain sewing work and are designed accordingly. Depending on the type and equipment of the sewing machine, the number of associated sewing feet varies and it is often quite difficult to distinguish between the different feet. Various arrangements have therefore become known to facilitate the differentiation, such as numbers, characters, color codes and the like. However, if the operator attaches a wrong presser foot to the machine, no precautions are taken to alert them to the fact.

Aus der US-PS-3 926 133 ist eine Nähmaschine mit einer Sicherungsvorrichtung bekannt, bei welcher das Anbringen einer bestimmten, für den Zick-Zack-Betrieb nicht geeigneten Stichplatte den Zick-Zack-Mechanismus der Maschine außer Betrieb setzt, um Schaden zu vermeiden. Jedoch unterscheidet die Maschine lediglich zwei Zustände voneinander und es wird kein Vergleich zwischen dem eingesetzten Element und einer bestimmten Maschineneinstellung vorgenommen, um das Anbringen eines richtigen oder falschen Elementes anzuzeigen.From US-PS-3 926 133 a sewing machine with a securing device is known, in which the attachment of a certain stitch plate which is not suitable for the zigzag operation disables the zigzag mechanism of the machine in order to avoid damage . However, the machine only distinguishes two states from one another and no comparison is made between the element used and a specific machine setting in order to indicate the fitting of a correct or incorrect element.

Es ist das Ziel vorliegender Erfindung, Mittel vorzusehen, welche das Einsetzen eines falschen Nähfußes anzeigen und/oder verhindern, bzw. die Inbetriebnahme der Maschine verhindern, wenn dadurch ein Schaden entstehen könnte (Nadelbruch, Beschädigung des Nähfußes). Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß die Nähmaschine erste Mittel, welche beim Einsetzen eines Nähfußes eine dem eingesetzten Nähfuß entsprechende Information liefern, zweite Mittel, welche eine der Maschineneinstellung entsprechende Information liefern und elektronische Mittel aufweist, welche mit den ersten und zweiten Mitteln verbunden sind, um die Informationen, welche von den ersten und zweiten Mitteln stammen, zu vergleichen und um festzustellen, ob der eingesetzte Nähfuß der Maschineneinstellung entspricht, wobei Anzeigemittel, welche durch die elektronischen Mittel gesteuert werden und am Nähmaschinengehäuse angebracht sind zur Anzeige über das Einsetzen eines richtigen oder falschen Nähfußes vorgesehen sind.It is the aim of the present invention to provide means which indicate and / or prevent the insertion of the wrong presser foot, or prevent the machine from being started up if damage could result (needle breakage, damage to the presser foot). This aim is achieved according to the invention in that the sewing machine has first means which, when a presser foot is inserted, provide information corresponding to the presser foot used, second means which provide information corresponding to the machine setting and electronic means which are connected to the first and second means to compare the information coming from the first and second means and to determine whether the presser foot used corresponds to the machine setting, display means which are controlled by the electronic means and are attached to the sewing machine housing for indicating the insertion of a correct one or wrong presser foot are provided.

Es wird damit möglich, das Einsetzen eines falschen Nähfußes optisch und/oder akustisch anzuzeigen, das vollständige Einsetzen oder Befestigen eines falschen Nähfußes zu sperren oder die Stromzufuhr zum Motor zu unterbrechen, wenn ein falscher Nähfuß eingesetzt ist.This makes it possible to visually and / or acoustically indicate the insertion of a wrong presser foot, to block the complete insertion or fastening of a wrong presser foot or to interrupt the power supply to the motor if a wrong presser foot is inserted.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt eine Teilhinteransicht einer Nähmaschine,
  • Fig. 2 zeigt eine Teilseitenansicht derselben,
  • Fig. 3 ist eine schematische Darstellung der Hilfsvorrichtung und
  • Fig. 4 zeigt den Nähfuß allein in Seitenansicht.
The invention is explained in more detail below with reference to an embodiment shown in the drawing.
  • 1 shows a partial rear view of a sewing machine,
  • 2 shows a partial side view of the same,
  • Fig. 3 is a schematic representation of the auxiliary device and
  • Fig. 4 shows the presser foot alone in side view.

Am Gestell 1 der Nähmaschine ist in üblicher Weise eine Nadelstange 2 mit der Nadel 3 beweglich gelagert, und neben der Nadelstange befindet sich die Nähfußstange 4. An der Nähfußstange 4 ist der Nähfuß 5 mit seinem Schaft 6 und einem Kupplungsteil 7 befestigt und mittels eines schwenkbaren Hebels 8, dessen Nase 9 unter einen Nocken 10 des Nähfußes greift, am Kupplungsteil 11 der Näßfußstange 4 gesichert. Durch Hochschwenken des Hebels 8 kann der Nähfuß entriegelt und aus dem Kupplungsteil 11 der Nähfußstange 4 entfernt werden, um nachträglich einen anderen, einer vorgewählten Maschineneinstellung entsprechenden Nähfuß anzubringen.On the frame 1 of the sewing machine, a needle bar 2 is movably mounted with the needle 3 in a conventional manner, and the presser foot bar 4 is located next to the needle bar. The presser foot 5 is fastened to the presser foot bar 4 with its shaft 6 and a coupling part 7 and by means of a pivotable one Lever 8, the nose 9 engages under a cam 10 of the presser foot, secured to the coupling part 11 of the wet foot rod 4. By swiveling the lever 8 up, the presser foot can be unlocked and removed from the coupling part 11 of the presser foot rod 4 in order to subsequently attach another presser foot corresponding to a preselected machine setting.

Wie die Fig. 3 und 4 zeigen, weist der Kupplungsteil 7 des Nähfußes auf einer Seite einer erhöhte Rippe 12 auf, die mit Nocken 13 an wenigstens vier bestimmten Stellen versehen ist. Im Kupplungsteil 11 der Nähfußstange 4 ist je einem der Nocken 13 gegenüber ein Schalter 14 angeordnet. Wie in Fig. 3 angedeutet, sind diese Schalter normalerweise offen, werden aber geschlossen, wenn ein ihnen zugeordneter Nocken 13 beim vollständigen Einsetzen der Nähfußkupplung 7 in die Nähfußstangenkupplung 11 den Schalter betätigt. Beim dargestellten Ausführungsbeispiel sind alle Stellen mit Nokken 13 besetzt. Es können aber beliebige Kombinationen von Nocken vorhanden sein, was insgesamt 16 verschiedene Kombinationen erlaubt. Es könnten also 16 verschiedene Nähfüße mit individuell zugeordneten Nockenkombinationen gekennzeichnet werden. Werden 5 Nockenstellen vorgesehen, erhöht sich die Zahl der Kombinationsmöglichkeiten auf 25 usw.3 and 4 show, the coupling part 7 of the presser foot has on one side a raised rib 12 which is provided with cams 13 at at least four specific points. In the coupling part 11 of the presser foot rod 4, one of the cams 13 is arranged opposite a switch 14. As indicated in FIG. 3, these switches are normally open, but are closed when a cam 13 assigned to them actuates the switch when the presser foot coupling 7 is fully inserted into the presser foot rod coupling 11. In the illustrated embodiment, all positions are occupied by cams 13. However, any combination of cams can be present, which allows a total of 16 different combinations. So 16 different sewing feet could be identified with individually assigned cam combinations. If 5 cam positions are provided, the number of possible combinations increases to 25, etc.

Alle Schalter 14 sind mit einer elektronischen Steuerschaltung 15, beispielsweise einem Mikroprozessor verbunden. Mittels einer Eingabevorrichtung 16 kann der Steuerschaltung 15 eine codierte Information zugeführt werden, welche einer bestimmten Einstellung der Nähmaschine für eine bestimmte Näharbeit entspricht. Durch Vergleich in der Steuerschaltung 15 dieser Information mit der durch die Schalter 14 gelieferten Information, kann ermittelt werden, ob der eingesetzte Nähfuß der Einstellung der Nähmaschine bzw. der vorgewählten Näharbeit entspricht oder nicht. Je nachdem, ob Entsprechung gegeben ist oder nicht, wird über Ausgänge der Steuerschaltung 15 eine grüne Anzeigelampe 17 oder eine rote Anzeigelampe 18, die am Nähmaschinengehäuse über der Nähfußstange 4 angeordnet sind, aktiviert. Die grüne Lampe zeigt dabei an, daß der richtige Nähfuß eingesetzt ist, während die rote Lampe anzeigt, daß ein falscher Nähfuß eingesetzt ist. Die Bedienungsperson kann dementsprechend den falschen Nähfuß entfernen und den richtigen aussuchen. Jedenfalls wird die Bedienungsperson darauf aufmerksam gemacht, daß etwas nicht übereinstimmt, d. h. die rote Warnlampe leuchtet immer dann auf, wenn entweder ein falscher Nähfuß zum gewünschten Arbeitsprogramm gewählt wird oder wenn die Maschine für dieses Arbeitsprogramm nicht korrekt eingestellt worden ist. Es kann also jedenfalls korrigiert werden, bis die grüne Lampe aufleuchtet und damit Übereinstimmung des gewählten Programms bzw. der gewählten Einstellung mit dem gewählten Nähfuß anzeigt. Durch die übliche Anordnung der roten Warnlampe über der grünen Lampe können auch farbenblinde Bedienungspersonen die Anzeige korrekt interpretieren.All switches 14 are connected to an electronic control circuit 15, for example a microprocessor. Using an input device 16, the control circuit 15 can be supplied with coded information which corresponds to a specific setting of the sewing machine for a specific sewing work. By comparing this information in the control circuit 15 with the information provided by the switches 14, it can be determined whether the presser foot used corresponds to the setting of the sewing machine or the preselected sewing work or not. Depending on whether there is correspondence or not, a green indicator lamp 17 or a red indicator lamp is output via the control circuit 15 18, which are arranged on the sewing machine housing above the presser foot rod 4, are activated. The green lamp indicates that the correct presser foot is inserted, while the red lamp indicates that the wrong presser foot is inserted. Accordingly, the operator can remove the wrong presser foot and choose the right one. In any case, the operator is made aware that something does not match, ie the red warning lamp lights up whenever either a wrong presser foot is selected for the desired work program or if the machine has not been correctly set for this work program. In any case, it can be corrected until the green lamp lights up, indicating that the selected program or setting matches the selected presser foot. Due to the usual arrangement of the red warning lamp above the green lamp, color-blind operators can correctly interpret the display.

Vorzugsweise kann die bisher beschriebene Hilfsvorrichtung an einer Nähmaschine angewendet werden, welche ohnehin elektronische Mittel zur Anzeige von Anweisungen zur korrekten Einstellung und Ausrüstung der Nähmaschine entsprechend einem gewünschten Programm bzw. den Bedingungen einer bestimmten Näharbeit aufweist. Eine solche Nähmaschine ist in der GB-A-2051152 der Anmelderin beschrieben. Wie Fig. 2 zeigt, sind über der Nadelstange 2 bzw. über der Nähfußstange 4 die Symbole der Nadel bzw. des Nähfußes angebracht und diesen Symbolen sind Anzeigefelder 19 bzw. 20 und 21 zugeordnet, an welchen die erforderlichen Nadeln bzw. Nähfüße anzeigende Ziffern erscheinen. Diese Ziffern befinden sich auch auf den Nähfüßen, was bereits die Auswahl des richtigen Nähfußes erheblich erleichtert. Die oben beschriebene Vorrichtung dient dazu, trotzdem noch auftretende Irrtümer anzuzeigen und damit unerwünschte Nähvorgänge oder Beschädigungen der Nadel oder des Nähfußes zu vermeiden.The previously described auxiliary device can preferably be used on a sewing machine, which anyway has electronic means for displaying instructions for correct setting and equipping the sewing machine in accordance with a desired program or the conditions of a specific sewing work. Such a sewing machine is described in the applicant's GB-A-2051152. As shown in FIG. 2, the symbols of the needle and the presser foot are attached above the needle bar 2 and above the presser foot rod 4 and these symbols are assigned display fields 19, 20 and 21, on which the numbers indicating the required needles or presser feet appear . These digits are also on the presser feet, which makes the selection of the right presser foot considerably easier. The device described above is used to indicate errors that still occur and thus to avoid undesired sewing processes or damage to the needle or the presser foot.

Beim dargestellten Ausführungsbeispiel erfolgt ausschließlich eine optische Anzeige darüber, ob der richtige oder ein falscher Nähfuß eingesetzt sei. Es könnte zusätzlich eine akustische Anzeige erfolgen, wenn ein falscher Nähfuß eingesetzt ist, um die Bedienungsperson noch eindrücklicher auf den Fehler aufmerksam zu machen. Es könnte aber außerdem eine eigentliche Sperrvorrichtung vorgesehen sein, welche entweder das definitive Einsetzen oder Befestigen des Nähfußes verhindert oder aber bei eingesetztem, falschem Nähfuß den Antrieb der Nähmaschine sperrt. Beim dargestellten Ausführungsbeispiel könnte eine elektromechanische Sperrvorrichtung vorgesehen sein, welche die endgültige Befestigung des Nähfußes durch Herunterschwenken des Hebels 8 verhindert.In the illustrated embodiment, there is only a visual display of whether the right or wrong presser foot is used. There could also be an acoustic signal if a wrong presser foot is inserted to make the operator more aware of the error. However, an actual locking device could also be provided, which either prevents the definitive insertion or fastening of the presser foot or blocks the drive of the sewing machine when the wrong presser foot is inserted. In the illustrated embodiment, an electromechanical locking device could be provided, which prevents the final attachment of the presser foot by pivoting the lever 8 down.

Anstelle der dargestellten Mittel zum (dentifizieren des eingesetzten Nähfußes können andere geeignete Fühler, beispielsweise induktive, kapazitive oder piezoelektrische Wandler vorgesehen sein. Entsprechend können am Kupplungsteil 7 des Nähfußes andere Geber angeordnet sein, auf welche die Fühler im Kupplungsteil der Nähfußstange 4 ansprechen.Instead of the means shown (for diagnosing the sewing foot used, other suitable sensors, for example inductive, capacitive or piezoelectric transducers, can be provided. Correspondingly, other sensors can be arranged on the coupling part 7 of the sewing foot, to which the sensors in the coupling part of the sewing foot rod 4 respond.
