Description

Die Erfindung betrifft eine Nähvorrichtung mit einer Nähmaschine, die einen Nähkopf aufweist, unter dem eine zu vernähende Stoffbahn mit einer veränderbaren Geschwindigkeit V2 hindurchführbar ist, und mit einer neben der Nähmaschine angeordneten Auflage für die Stoffbahn (siehe US-A-4 327 653 ).The invention relates to a sewing apparatus with a sewing machine, which has a sewing head, under which a fabric web to be sewn with a variable speed V 2 can be passed, and arranged with an adjacent to the sewing machine pad for the fabric (see US-A-4,327,653 ).

Nähvorrichtungen der genannten Art sind seit langem bekannt und dienen dazu, die Stoffbahn entweder mit einem weiteren Stoffteil oder beispielsweise unter Bildung eines Umschlages oder eines Saumes mit sich selbst zu vernähen. Der Nähkopf weist eine motorisch angetriebene auf und ab bewegte Nadel auf, die in bekannter Weise einen Nähfaden durch die Stoffbahn treibt. Bei der nähenden Bewegung der Nadel wird gleichzeitig die Stoffbahn unter dem Nähkopf hindurchtransportiert, wobei die Geschwindigkeit der Nadel und entsprechend die Transportgeschwindigkeit der Stoffbahn von dem Benutzer üblicherweise mittels eines Fußpedals variiert werden kann.Sewing devices of the type mentioned have long been known and serve to sew the fabric either with another piece of fabric or, for example, to form an envelope or a hem with itself. The sewing head has a motor driven up and down moving needle, which drives a sewing thread through the fabric in a known manner. During the sewing movement of the needle, at the same time, the fabric is transported under the sewing head, whereby the speed of the needle and, correspondingly, the transport speed of the fabric can be varied by the user, usually by means of a foot pedal.

Um die auszubildende Naht an der Stoffbahn mit hoher Präzision auszubilden, ist es sinnvoll oder sogar notwendig, dass die Stoffbahn möglichst glatt ausgelegt ist und während des Nähvorgangs keinen übermäßigen Verwerfungen ausgesetzt ist. Zu diesem Zweck ist neben dem Nähkopf eine Auflage für die Stoffbahn ausgebildet. Eine relativ kleine Stoffbahn kann üblicherweise auf der Auflage flach aufgenommen und somit gut vernäht werden. Dies ist jedoch für eine sehr lange Stoffbahn schwierig.To form the seam to be formed on the fabric with high precision, it is useful or even necessary that the fabric is designed as smooth as possible and during sewing is not subject to excessive distortion. For this purpose, a support for the fabric is formed next to the sewing head. A relatively small fabric can usually be taken flat on the support and thus well sewn. However, this is difficult for a very long fabric.

Bei industriellen Näharbeiten müssen viele relativ große Stoffbahnen nacheinander vernäht werden. Es ist zu diesem Zweck bekannt, die Stoffbahnen in einem Stapel aufeinanderzulegen und auf der neben dem Nähkopf ausgebildeten Auflage abzulegen. Der Benutzer vernäht zunächst die obere Stoffbahn des Stapels und schlägt diese dann um, um Zugriff auf die darunterliegende Stoffbahn zu erhalten und diese zu vernähen. Dieses Vorgehen wird so oft wiederholt, bis alle Stoffbahnen des Stapels vernäht sind. Da die Stoffbahnen des Stapels zusammen ein relativ großes Gewicht haben und sich nur schwer handhaben lassen, ist es schwierig, alle Stoffbahnen in gewünschter Ausrichtung unter dem Nähkopf hindurchzuführen.In industrial sewing, many relatively large lengths of fabric need to be sewn one after the other. It is known for this purpose, superimpose the panels in a stack and store on the trained next to the sewing head pad. The user first sews the top panel of the stack and then knocks it over to gain access to and sew the underlying panel. This procedure is repeated until all panels of the stack are sewn. Since the webs of the stack together have a relatively large weight and are difficult to handle, it is difficult to pass all the webs in the desired orientation under the sewing head.

Der Erfindung liegt die Aufgabe zugrunde, eine Nähvorrichtung der genannten Art zu schaffen, mit der sich auch große Stoffbahnen in vorbestimmter Ausrichtung unter dem Nähkopf hindurchführen lassen.The invention has for its object to provide a sewing device of the type mentioned, with which can be pass even in a predetermined orientation under the sewing head and large lengths of fabric.

Diese Aufgabe wird erfindungsgemäß durch eine Nähvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die Auflage, auf der die Stoffbahn oder der Stapel von Stoffbahnen liegt, an einem Traggestell ausgebildet ist, das relativ zur Nähmaschine mit einer veränderbaren Geschwindigkeit V1 verfahren werden kann. Während des Vernähens der Stoffbahn wird diese nicht nur unter dem Nähkopf hindurchgeführt, sondern gleichzeitig wird durch Verfahren der Auflage die gesamte Stoffbahn in die gleiche Richtung mitbewegt, so dass übermäßige Verwerfungen der Stoffbahn vermieden werden können. Dieses Vorgehen ist insbesondere sinnvoll und hilfreich, wenn die zu vernähende Stoffbahn Teil eines aus vielen übereinander liegenden Stoffbahnen aufgebauten Stapels ist.This object is achieved by a sewing device with the features of claim 1. It is provided that the support on which the fabric or the stack of fabric webs is formed on a support frame which can be moved relative to the sewing machine with a variable speed V 1 . During the sewing of the fabric, this is not only under the Sewing head passed, but at the same time by moving the support the entire fabric web moves in the same direction, so that excessive distortions of the fabric can be avoided. This procedure is particularly useful and helpful if the fabric to be sewn part of a stack constructed of many superimposed panels is.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Geschwindigkeit V1 des Traggestells und somit der auf der Auflage liegenden Stoffbahn und die Geschwindigkeit V2 des Nähkopfes bzw. der Stoffbahn unterhalb des Nähkopfes miteinander synchronisiert sind. Wenn der Benutzer der Nähvorrichtung durch Betätigung beispielsweise der Fußpedale die Geschwindigkeit der Nadel und somit der Stoffbahn am Nähkopf erhöht, erhöht sich in gleicher Weise auch die Geschwindigkeit der Bewegung des Traggestells und somit der darauf aufliegenden Stoffbahn. Eine Unterbrechung des Nähvorgangs und somit ein Anhalten der Bewegung der Nadel führt in gleichartiger Weise zu einem Anhalten des Traggestells. Auf diese Weise ist sichergestellt, dass die auf der Auflage des Traggestells liegende Stoffbahn in gleichbleibender Ausrichtung unter dem Nähkopf hindurchgeführt wird.In a preferred embodiment of the invention, it is provided that the speed V 1 of the support frame and thus the lying on the support panel and the speed V 2 of the sewing head or the fabric below the sewing head are synchronized with each other. If the user of the sewing device increases the speed of the needle and thus of the fabric at the sewing head by actuating, for example, the foot pedals, the speed of movement of the support frame and thus of the fabric resting on it increases in the same way. An interruption of the sewing process and thus stopping the movement of the needle leads in a similar manner to a stop of the support frame. In this way it is ensured that the lying on the support of the support frame fabric is passed in a constant orientation under the sewing head.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Geschwindigkeit V1, mit der das Traggestell bewegt wird, gleich der Geschwindigkeit V2 ist, mit der die Stoffbahn unter dem Nähkopf hindurchgeführt wird und die von dem Benutzer eingestellt und verändert werden kann.In a preferred embodiment of the invention it is provided that the speed V 1 , with which the support frame is moved, equal to the speed V 2 , with which the fabric is passed under the sewing head and can be adjusted and changed by the user.

Das Traggestell kann mit einem Fahrwerk versehen und mit einem Antriebsmotor ausgerüstet sein, wobei es sich vorzugsweise um einen Servomotor handelt. In bevorzugter Ausgestaltung der Erfindung ist jedoch vorgesehen, dass das Traggestell auf einer Bühne angeordnet ist, die mittels eines Antriebs, beispielsweise mittels eines Servomotors, mit der Geschwindigkeit V1 verfahren wird. Diese Ausgestaltung hat den Vorteil, dass die Stoffbahn oder der aus mehreren Stoffbahnen gebildete Stapel auf der Auflage des Traggestells vorbereitet und dann auf die Bühne gefahren werden kann. Zu diesem Zweck kann die Bühne eine Rampe aufweisen, über die das Traggestell auf die Bühne aufschiebbar und von dieser herunterfahrbar ist.The support frame can be provided with a chassis and be equipped with a drive motor, which is preferably is a servomotor. In a preferred embodiment of the invention, however, it is provided that the support frame is arranged on a stage which is moved by means of a drive, for example by means of a servo motor, at the speed V 1 . This embodiment has the advantage that the fabric or the stack formed of several panels can be prepared on the support of the support frame and then driven onto the stage. For this purpose, the stage may have a ramp over which the support frame can be pushed onto the stage and lowered by the latter.

Eine definierte Bewegungsrichtung des Traggestells bzw. der Bühne relativ zu der vorzugsweise ortsfest angeordneten Nähmaschine ist gegeben, wenn die Bühne oder das Traggestell längs einer stationären Führung verfahren werden.A defined direction of movement of the support frame or the stage relative to the preferably stationary arranged sewing machine is given when the stage or the support frame are moved along a stationary guide.

Zur Synchronisation der Geschwindigkeit des Nähkopfes bzw. der Stoffbahn unterhalb des Nähkopfes sowie des Traggestells bzw. der darauf befindlichen Stoffbahn kann eine Steuervorrichtung vorgesehen sein. Die Steuervorrichtung erfasst die Geschwindigkeit V2 der Stoffbahn am Nähkopf, was entweder durch Erfassung der Stellung der Fußpedale und/oder durch Erfassung der Geschwindigkeit der Nadel geschieht. Auf Grundlage der festgestellten Geschwindigkeit V2 wird der Antrieb des Traggestells oder der Bühne entsprechend angesteuert, so dass die Geschwindigkeit V1 der Bühne oder des Traggestells der ermittelten Geschwindigkeit V2 entspricht.For synchronization of the speed of the sewing head or the fabric below the sewing head and the support frame or the fabric thereon, a control device may be provided. The controller detects the speed V 2 of the fabric at the sewing head, either by detecting the position of the foot pedals and / or by detecting the speed of the needle. Based on the detected speed V 2 , the drive of the support frame or the stage is driven accordingly, so that the speed V 1 of the stage or the support frame of the determined speed V 2 corresponds.

Weitere Einzelheiten und Merkmale der Erfindung sind aus der folgenden Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung ersichtlich, wobei die einzige Figur eine schematische perspektivische Darstellung der erfindungsgemäßen Nähvorrichtung zeigt.Further details and features of the invention will become apparent from the following description of an embodiment with reference to the drawing, wherein the only Figure shows a schematic perspective view of the sewing device according to the invention.

Eine Nähvorrichtung 10 umfasst ein ortsfestes Podest 13, auf dem ein Tisch 14 angeordnet ist, auf dessen Oberseite eine Nähmaschine 11 üblicher Bauart befestigt ist. Die Nähmaschine 11 besitzt einen Nähkopf 12, der eine motorisch angetriebene, nicht näher dargestellte Nadel aufweist, die in üblicher Weise auf und ab bewegt wird. Eine zu vernähende Stoffbahn S kann bei Aktivierung der Nähmaschine 11 mit einer Geschwindigkeit V2 unter dem Nähkopf 12 hindurchgeführt werden, wie es durch den Pfeil M2 angedeutet ist.A sewing apparatus 10 comprises a stationary pedestal 13, on which a table 14 is arranged, on the upper side of which a sewing machine 11 of conventional design is fastened. The sewing machine 11 has a sewing head 12, which has a motor-driven, not shown needle, which is moved in the usual way up and down. When the sewing machine 11 is activated, a fabric S to be sewn can be passed under the sewing head 12 at a speed V 2 , as indicated by the arrow M 2 .

Neben dem Podest 13 ist eine Bühne 21 vorgesehen, auf deren Oberseite 23 ein Traggestell 18 über einen Rampe 22 aufgeschoben werden kann. Das Traggestell 18 umfasst ein Fahrwerk 20 sowie einen oberen Auflagerkörper 19, der eine Auflage 17 für eine oder mehrere Stoffbahnen S bildet.In addition to the pedestal 13, a stage 21 is provided, on the upper side 23 of which a support frame 18 can be slid over a ramp 22. The support frame 18 includes a chassis 20 and an upper support body 19 which forms a support 17 for one or more panels S.

Die Bühne 21 ist mittels eines nicht dargestelltem Antriebs längs einer Führung motorisch verfahrbar, wie es durch den Doppelpfeil M1 angedeutet ist, wobei die Bewegungsrichtung M1 der Bühne 21 und des darauf befindlichen Traggestells 18 parallel zu der Bewegung M2 der Stoffbahn während des Nähvorgangs ist.The stage 21 is motor-driven by means of a not shown drive along a guide, as indicated by the double arrow M 1 , wherein the direction of movement M 1 of the stage 21 and the supporting frame 18 thereon parallel to the movement M 2 of the fabric during the sewing process is.

Die Geschwindigkeit der Nadel des Nähkopfes 12 und die damit einhergehende Geschwindigkeit V2 der Stoffbahn unterhalb des Nähkopfes 12 während des Nähvorganges wird erfasst und über eine Leitung 15 einer Steuervorrichtung 16 zugeleitet, die daraus die für die Bühne 21 geeignete Geschwindigkeit V1 berechnet und den Antrieb der Bühne 21 entsprechend über eine Leitung 24 ansteuert. Auf diese Weise kann die Bühne 21 mit dem darauf befindlichen Traggestell 18 und der auf der Auflage 17 befindlichen Stoffbahn S während des Nähvorgange mit der gleichen Geschwindigkeit unmittelbar an der Nähmaschine 11 vorbeigefahren werden, die der Geschwindigkeit V2 entspricht, mit der die Stoffbahn S von dem Benutzer der Nähvorrichtung 10 unter dem Nähkopf 12 hindurchgeführt wird.The speed of the needle of the sewing head 12 and the associated speed V 2 of the fabric below the sewing head 12 during the sewing process is detected and fed via a line 15 to a control device 16, which calculates the speed suitable for the stage 21 V 1 and the drive the stage 21 accordingly via a line 24 drives. This way you can the stage 21 with the support frame 18 thereon and the fabric S on the support 17 are passed directly past the sewing machine 11 during the sewing process at the same speed, which corresponds to the speed V 2 with which the fabric S is conveyed by the user of the sewing apparatus 10 is passed under the sewing head 12.

Sobald die Stoffbahn S vernäht ist, kehrt die Bühne 21 in die Ausgangsstellung zurück. Der Benutzer kann dann im Falle eines Stapels von Stoffbahnen die obere Stoffbahn umschlagen und die darunter liegende Stoffbahn in gleicher Weise vernähen. Alternativ ist es möglich, das Traggestell 18 über die Rampe 22 von der Bühne 21 herunterzufahren und ein anderes Traggestell mit einer anderen Stoffbahn oder einem anderen Stoffbahn-Stapel auf die Bühne 21 zu schieben und mit dem Vernähen dieser Stoffbahn in genanntem Sinne zu beginnen.Once the fabric S is sewn, the stage 21 returns to the starting position. The user can then turn over in the case of a stack of panels the upper panel and sew the underlying fabric in the same way. Alternatively, it is possible to lower the support frame 18 via the ramp 22 from the stage 21 and to push another support frame with another fabric or other fabric stack on the stage 21 and to begin sewing this fabric in the sense mentioned.
