Description
Die Erfindung betrifft eine Nähmaschine, umfassend ein Nähmaschinenoberteil mit einem Rahmen, einer Nadelstange und einer Nähfußstange, die parallel zueinander in dem Gehäuse hin- und herbewegbar geführt sind, und einer Antriebseinrichtung für die Nadelstange und den Nähfuß.The invention relates to a sewing machine comprising a sewing machine upper part a frame, a needle bar and a presser foot bar that are parallel to each other are guided back and forth in the housing, and a drive device for the needle bar and the presser foot.
Bei herkömmlichen Nähmaschinen werden die Nadelstange und der Nähfuß sowie gegebenenfalls auch der Fadenziehhebel von einer gemeinsamen Welle her angetrieben, deren Rotationsbewegung jeweils über eine Kurbel oder einen Exzenterantrieb in eine lineare Hin- und Herbewegung der Nadelstange und des Nähfußes umgesetzt wird. Dies hat nicht nur den Nachteil, dass relativ viele Einzelteile benötigt und relativ große Massen bewegt werden müssen, sondern dass auch die Bewegungsphasen der Nadelstange und des Nähfußes innerhalb eines Zyklus' praktisch nicht verändert werden können. Der Hub der Stangen ist durch eine Verstellung des Exzenters zwar in der Regel in begrenztem Umfange veränderbar, jedoch muss für die Verstellung des Hubes der Nähantrieb unterbrochen werden. In conventional sewing machines, the needle bar and the presser foot as well if necessary also the thread pull lever from a common shaft driven, the rotational movement of each via a crank or a Eccentric drive in a linear reciprocating movement of the needle bar and the Presser foot is implemented. Not only does this have the disadvantage of being relatively many Individual parts needed and relatively large masses have to be moved, but that also the movement phases of the needle bar and the presser foot within one Cycle 'can practically not be changed. The stroke of the bars is through a Adjustment of the eccentric can generally be changed to a limited extent, however, the sewing drive must be interrupted to adjust the stroke.
Aus der DE 198 27 846 A1 ist bereits eine Industrienähmaschine bekannt, bei welcher die Nadelstange mittels eines elektromagnetischen Linearantriebes linear hin- und herbewegt wird. Durch entsprechende Ansteuerung der entlang des Nadelstangenweges angeordneten Elektromagneten kann die Nadelstange entsprechend einem vorgebbaren Geschwindigkeits- bzw. Beschleunigungsprofil bewegt werden. Neben dem beträchtlichen Aufwand für die Ansteuerung der Vielzahl der Elektromagneten haftet dieser Lösung vor allem der Nachteil an, dass die für eine qualitätsgerechte Stichbildung erforderliche Genauigkeit der Endlagen des Nadelstangenhubes nur bei sehr geringen Arbeitsgeschwindigkeiten erreicht werden kann. Darüber hinaus ist dieses Antriebsprinzip nur für geradlinige Bewegungen anwendbar und kann daher nicht problemlos auf andere Bewegungsformen, beispielweise die rotatorische Bewegung eines Umlaufgreifers übertragen werden.An industrial sewing machine is already known from DE 198 27 846 A1, at which linearly the needle bar by means of an electromagnetic linear drive is moved back and forth. By appropriate control of the along the Needle bar path arranged electromagnet can the needle bar according to a predeterminable speed or acceleration profile be moved. In addition to the considerable effort for controlling the large number the electromagnet of this solution has the particular disadvantage that the for a quality-appropriate stitch formation required accuracy of the end positions of the Needle bar stroke can only be achieved at very low working speeds can. In addition, this drive principle is only for straight-line movements applicable and can therefore not easily be used for other forms of movement, for example, the rotary movement of a rotary gripper can be transmitted.
Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu beseitigen und eine Nähmaschine der eingangs genannten Art anzugeben, die eine höhere Flexibilität bei der Steuerung der Bewegung von Nadelstange und Nähfuß, insbesondere bei der Einstellung des Nadelhubes unter Beibehaltung einer höchstmöglichen Präzision gewährleistet. Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Anspruch 1 angegebenen Merkmalen. Zweckmäßige und vorteilhafte Weiterbildungen sind in den Unteransprüchen 2 bis 8 wiedergegeben.The invention has for its object to eliminate the disadvantages mentioned and to specify a sewing machine of the type mentioned, the higher Flexibility in controlling the movement of the needle bar and presser foot, especially when setting the needle stroke while maintaining a guaranteed the highest possible precision. This task is solved according to the invention with the features specified in claim 1. expedient and advantageous developments are in the subclaims 2 to 8 played.
Kern der erfindungsgemäßen Lösung ist, dass die Nadelstange und die Nähfußstange jeweils mit einer Zahnstange gekoppelt sind, die jeweils im Eingriff mit einem Antriebszahnrad steht, das von einem eigenen programmgesteuerten Elektromotor antreibbar ist.The essence of the solution according to the invention is that the needle bar and the Presser foot rack are each coupled to a rack, each of which engages with a drive gear, which is controlled by its own program Electric motor can be driven.
Nadelstange und Nähfußstange können bei der erfindungsgemäßen Lösung völlig unabhängig voneinander mit hoher Präzision auf- und abbewegt werden. Es kann nicht nur das Geschwindigkeits- und/oder Beschleunigungsprofil separat eingestellt und gegebenenfalls verändert werden, sondern es kann auch der Nadelhub während des Nähbetriebes je nach Wunsch verändert werden. Dies ist insbesondere für Tuftingmaschinen und Nähgut von Bedeutung, dessen Materialstärke sich kontinuierlich oder sprunghaft ändert. Hier ist es wichtig, den Nadelhub entsprechend der Materialstärke zu verändern, um eine saubere Stichbildung zu erreichen. Gleichzeitig kann der Nähfuß solange gegen die Oberfläche des Nähgutes gedrückt werden, wie dies für das Herausziehen der Nadel aus dem Nähgut und das Festhalten des Fadens in dem Nähgut erforderlich ist, da die Bewegung des Nähfußes unabhängig von der Bewegung der Nadelstange steuerbar ist. Die Nähgeschwindigkeit kann ohne Mühe an die Materialstärke und den Nadelhub angepasst werden.Needle bar and presser foot bar can completely in the solution according to the invention can be moved up and down independently of each other with high precision. It can not only set the speed and / or acceleration profile separately and changed if necessary, but it can also be the needle stroke during of the sewing company can be changed as required. This is especially for Tufting machines and sewing material of importance, the material thickness of which changes continuously or by leaps and bounds. Here it is important to adjust the needle stroke accordingly change the material thickness to achieve a clean stitch formation. At the same time, the presser foot can be pressed against the surface of the sewing material be like this for pulling the needle out of the fabric and that Sticking the thread in the material is required because the movement of the Presser foot is controllable regardless of the movement of the needle bar. The Sewing speed can be easily adjusted to the material thickness and the needle stroke be adjusted.
Vorzugsweise sind die Nadelstange und die Nähfußstange einstückig mit der jeweiligen Zahnstange ausgebildet, d.h. die Nadelstange und die Nähfußstange können selber eine entsprechende Zahnung ausweisen.The needle bar and the presser foot bar are preferably integral with the respective rack, i.e. the needle bar and the presser foot bar can identify a corresponding toothing themselves.
Bei einer bevorzugten Ausführungsform der Erfindung sind die Nadelstange und die Nähfußstange zusammen mit mindestens den Antriebsrädern an einem Schlitten angeordnet, der in dem Gehäuse parallel zur Nährichtung verschiebbar geführt und mittels eines separaten programmgesteuerten Schlittenantriebes verstellbar ist. Diese Ausführung ermöglicht eine Bewegung der Nadelstange und der Nähfußstange in bzw. entgegen der positiven Nährichtung. Hierdurch ist es möglich, die gesamte Nähmaschine kontinuierlich mit einem hierfür geeigneten Manipulator, z.B. einem Industrieroboter entlang der vorgesehenen Nahtlinie zu bewegen. Eine bei Industrienähmaschinen übliche und wegen der ständigen Beschleunigung und Abbremsung die Arbeitsgeschwindigkeit begrenzende intermittierende Relativbewegung zwischen Nähgut und Nähmaschine ist somit nicht erforderlich. Wichtig ist hierbei, dass das Bewegungsgesetz für die Schlittensteuerung so generiert wird, dass weder die Nadel noch der Nähfuß eine Bewegung in Nährichtung relativ zum Nähgut ausführen, solange sich eines dieser Nähwerkzeuge mit dem Nähgut in Kontakt befindet.In a preferred embodiment of the invention, the needle bar and the Presser foot bar together with at least the drive wheels on one slide arranged, which is guided in the housing parallel to the sewing direction and is adjustable by means of a separate program-controlled slide drive. This design allows the needle bar and the Presser foot bar in or against the positive sewing direction. This makes it possible the entire sewing machine continuously with a suitable manipulator, e.g. an industrial robot to move along the intended seam line. A usual in industrial sewing machines and because of the constant acceleration and Decelerating intermittent relative movement limiting working speed between the material and the sewing machine is therefore not necessary. Important is here that the motion law for the slide control is generated in such a way that neither the needle nor the presser foot move relative to the sewing direction Execute the sewing material as long as one of these sewing tools is in the sewing material Contact.
Bei der erfindungsgemäßen Lösung ist vorzugsweise auch der Fadengeber durch einen separaten programmgesteuerten Stellmotor antreibbar. Beispielsweise kann der Fadengeber einen an einer Zahnstange angeordneten Fadenziehhebel haben, wobei die Zahnstange mit einem durch den Stellmotor angetriebenen Zahnrad im Eingriff steht. Dadurch kann auch die Zufuhr des Fadens zur Nadel von der Nadelbewegung selbst entkoppelt und für den jeweiligen Nähvorgang optimiert werden. Die Fadenspannung kann durch eine Fadenbremse mit programmgesteuert einstellbarer Bremswirkung eingestellt werden.In the solution according to the invention, the thread feeder is preferably also through a separate program-controlled servomotor can be driven. For example the thread take-up device has a thread pulling lever arranged on a toothed rack, the rack with a gear driven by the servomotor in Intervention stands. This also allows the thread to be fed to the needle from the Decoupled needle movement itself and optimized for the respective sewing process become. The thread tension can also be program-controlled by a thread brake adjustable braking effect can be set.
Dem Nähmaschinenoberteil kann ein Unterteil mit mindestens einem rotierenden oder oszillierenden Greifer zugeordnet sein, der von einem separaten programmgesteuerten Motor antreibbar ist, so dass auch andere Sticharten wie beispielsweise ein Kettenstich durchführbar sind.The lower part of the sewing machine can have at least one rotating part or oscillating gripper can be assigned that of a separate program-controlled Motor can be driven, so that other stitch types such as a chain stitch can be carried out.
