Abstract

The sewing machine has a laying surface for the fabric, which holds it stationary and in place by suction, while a sewing head (16) is moved along the stitching line. The fabric laying surface (11) is perforated, for suction at the under side to hold the fabric at its upper side through the perforations (20). The laying surface (11) is a perforated plate. An air-permeable cushion is under the laying surface (11), of an open-cell foam material. The laying surface (11) can also be the upper cover (21) of a cassette unit (23), with an under pressure within its interior. A projector, independently over the sewing machine and unaffected by vibrations, projects a line (26) on to the fabric, to show the seam sewing path line and a further line to show the fabric cutting line. The projector is a laser.

Description

Die Erfindung betrifft eine Nähmaschine mit zumindest einem in einer vorbestimmten Lage gehaltenen Stoffzuschnitt und einem längs einer am Stoffzuschnitt auszubildenden Naht verfahrbaren Nähkopf (Siehe US-A-3 839 973).The invention relates to a sewing machine with at least a fabric blank held in a predetermined position and one along one to be trained on the fabric cut Seam movable sewing head (see US-A-3 839 973).

Nähmaschinen finden bekanntlich Verwendung, um entweder einen Stoffzuschnitt umzunähen oder mehrere Stoffzuschnitte mittels einer Naht zu verbinden. Dabei werden insbesondere im privaten Bereich in der Regel Nähmaschinen verwendet, bei denen der Nähkopf feststeht und der Stoffzuschnitt entweder manuell oder mittels eines Antriebs unter dem Nähkopf hindurchgeführt wird, wobei der Nähkopf vom Stoffzuschnitt abhebbar und auf diesen absenkbar ist. Darüber hinaus finden insbesondere in der industriellen Fertigung zum Vernähen von relativ großen Stoffzuschnitten auch Nähmaschinen Verwendung, bei denen der oder die Stoffzuschnitte auf einem Auflagetisch aufliegen und auf diesem in vorbestimmter Lage gehalten sind, wobei der Nähkopf auf einem Wagen angeordnet ist, der entlang einer Führung längs dem Auflagetisch verfahrbar ist. Nachdem die Stoffzuschnitte auf dem Auflagetisch positioniert sind, läuft der eigentliche Nähvorgang bei gleichzeitigem Verfahren des Wagens im wesentlichen selbsttätig ab.As is well known, sewing machines are used to either to sew over a fabric cut or several fabric cuts to connect by means of a seam. In doing so usually sewing machines, especially in the private sector used, where the sewing head is fixed and the Fabric cutting either manually or using a drive is passed under the sewing head, the Sewing head can be lifted off the fabric cut and lowered onto it is. In addition, especially in the industrial manufacturing for sewing relatively large Fabric cuts also use sewing machines where the fabric cut or cuts on a support table lie on and held on it in a predetermined position the sewing head is arranged on a carriage, which can be moved along a guide along the support table is. After the fabric cuts on the support table the actual sewing process runs with simultaneous movement of the car essentially automatically.

Um einen exakten Nahtverlauf zu erhalten, ist es notwendig, die Stoffzuschnitte auf dem Auflagetisch sicher zu positionieren. Bei den bekannten Nähmaschinen geschieht dies dadurch, daß die Stoffzuschnitte von der Oberseite mit Hilfe einer Vielzahl von Stempeln gegen den Auflagetisch gespannt werden. Zusätzlich oder alternativ dazu können auch Klammern Verwendung finden, mit denen die Stoffzuschnitte ergriffen und gehalten werden. Es hat sich gezeigt, daß die Verwendung von Stempeln oder Klammer insbesondere bei dünnen, druckempfindlichen Stoffen zu einer Beschädigung führen kann, da die relativ hohen Haltekräfte konzentriert auf kleinen Flächen auf die Stoffzuschnitte einwirken. Darüber hinaus sind die Stoffzuschnitte mittels der Stempel oder Klammer nur punktuell gehalten, so daß es in den zwischen den Haltepunkten liegenden Abschnitten zu Verformungen kommen kann, wodurch die genaue Positionierung nachteilig beeinflußt ist.In order to obtain an exact seam course, it is necessary the fabric cuts on the support table securely position. Happens in the known sewing machines this in that the fabric cuts from the top with the help of a variety of stamps against the support table be excited. Additionally or alternatively brackets can also be used with which the Fabric cuts are taken and held. It has it has been shown that the use of stamps or brackets especially with thin, pressure-sensitive fabrics can cause damage because the relatively high Holding forces concentrated on the small areas Work on fabric cuts. In addition, the fabric cuts only punctually using the stamp or clip held so that it is in between the breakpoints lying sections can come to deformation, whereby the exact positioning adversely affects is.

Der Erfindung liegt die Aufgabe zugrunde, eine Nähmaschine der genannten Art zu schaffen, bei der eine schonende Halterung des Stoffzuschnittes zuverlässig gewährleistet ist.The invention has for its object a sewing machine to create the kind mentioned, with a gentle Reliability of the fabric cutting guaranteed is.

Diese Aufgabe wird erfindungsgemäß bei einer Nähmaschine der genannten Art dadurch gelöst, daß der Stoffzuschnitt mittels Unterdruck in seiner vorbestimmten Lage gehalten ist. Infolge des Unterdrucks wird der Stoffzuschnitt im wesentlichen vollflächig auf den Auflagetisch gesaugt, wodurch die Haltekräfte nicht punktuell, sondern über eine große Fläche auf den Stoffzuschnitt einwirken, so daß Spannungsspitzen und daraus resultierende Beeinträchtigungen des Stoffes vermieden sind.This object is achieved in a sewing machine of the type mentioned solved in that the fabric cut held in its predetermined position by means of negative pressure is. Due to the negative pressure, the fabric cut in the essentially sucked all over the support table, whereby the holding forces are not selective, but over affect a large area on the fabric cut, so that voltage spikes and resulting impairments of the substance are avoided.

Vorzugsweise ist eine perforierte Auflagefläche für den Stoffzuschnitt vorgesehen, die auf ihrer Unterseite mit einem Unterdruck beaufschlagt ist. Die perforierte Auflagefläche, bei der es sich beispielsweise um ein Lochblech handeln kann, besitzt eine ausreichende Stabilität, um die Stoffzuschnitte in vorgewünschter Position zu tragen. Desweiteren kann über die Anzahl und das Rastermaß der Perforationen der Auflagefläche die den Stoffzuschnitt auf die Auflagefläche saugende Haltekraft eingestellt und variiert werden. Insbesondere kann vorgesehen sein, daß die perforierte Auflagefläche auswechselbar ist, so daß die Nähmaschine hinsichtlich der Haltekraft für den Stoffzuschnitt auf der Auflagefläche in einfacher Weise an unterschiedliche Einsatzbedingungen und Stoffarten angepaßt werden kann.A perforated support surface for the Fabric cutting provided on the underside with a negative pressure is applied. The perforated contact surface, which is, for example, a perforated plate can act has sufficient stability to to carry the fabric cuts in the desired position. Furthermore, the number and pitch of the Perforations of the support surface which cut the fabric holding force set on the support surface and can be varied. In particular, it can be provided that the perforated support surface is interchangeable, so that the sewing machine with regard to the holding force for the Fabric cut on the support surface in a simple way to different conditions of use and types of fabrics can be adjusted.

Um über die gesamte Auflagefläche und somit an allen Perforationen bzw. Löchern eine möglichst gleichmäßigen Unterdruck zu erhalten, kann unterhalb der Auflagefläche ein Druckausgleichselement beispielsweise in Form eines luftdurchlässigen Polsterkörpers angeordnet sein, der in bevorzugter Ausgestaltung der Erfindung aus einem offenzelligen Schaumstoff besteht.In order to cover the entire contact area and therefore everyone Perforations or holes as uniform as possible Obtaining negative pressure can be below the contact surface a pressure compensation element, for example in the form of a air-permeable cushion body may be arranged, which in preferred embodiment of the invention from an open cell There is foam.

Ein konstruktiv einfacher Aufbau der Auflagefläche läßt sich erreichen, wenn diese die obere Abdeckung einer Kassette oder eines kassettenartigen Auflagetisches ist, deren bzw. dessen Innenraum mittels einer bekannten Saugpumpe auf dem Unterdruck gehalten ist.A structurally simple structure of the contact surface leaves reach themselves when this covers the top one Cassette or a cassette-like support table, whose or its interior by means of a known Suction pump is kept at the negative pressure.

Zum Vernähen von zwei Stoffzuschnitten werden diese in gewünschter Weise auf der Auflagefläche positioniert. Bei bemusterten Stoffen ist es notwendig, daß die Muster der miteinander zu vernähenden Stoffzuschnitte glatt bzw. kontinuierlich ineinander übergehen, was von einer Bedienperson bei der Positionierung der beiden Stoffzuschnitte überprüft wird. Für die Bedienperson ist es bei der gegenseitigen Ausrichtung der Muster der Stoffzuschnitte sehr hilfreich, wenn der genaue Verlauf der Naht bekannt und wahrnehmbar wäre. Um dies zu ermöglichen, ist in Weiterbildung der Erfindung vorgesehen, daß oberhalb der Nähmaschine eine Projektionseinrichtung insbesondere in Form eines Laserprojektors angeordnet ist, die auf die Stoffzuschnitte eine 1. Linie entsprechend dem Nahtverlauf projiziert. Zusätzlich dazu kann auch mittels eines Lasers eine 2. Linie auf die Stoffzuschnitte projiziert werden, die den Verlauf der Schnittkante nach dem Vernähen der Stoffzuschnitte anzeigt. Um die Projektionseinrichtung vor Vibrationen der Nähmaschine zu schützen, sollte sie unabhängig von dieser an der Decke des Raums angebracht sein, in dem die Nähmaschine betrieben wird.To sew two fabric cuts, these are cut in positioned as desired on the support surface. at patterned fabrics it is necessary that the pattern of the fabric blanks to be sewn together smooth or continuously merge into what an operator when positioning the two fabric cuts is checked. For the operator it is at the mutual alignment of the patterns of the fabric blanks very helpful if the exact course of the seam would be known and perceptible. To make this possible in further development of the invention provided that above the sewing machine in particular a projection device is arranged in the form of a laser projector, which on the Fabric cuts a 1st line according to the seam course projected. In addition to this, you can also use a second line on the fabric cuts are projected following the course of the cutting edge shows the sewing of the fabric cuts. To the projection device against vibrations of the sewing machine should protect them independently of this on the ceiling the room in which the sewing machine is operated becomes.

Nach dem gegenseitigen Ausrichten der Stoffzuschnitte wird die Saugpumpe aktiviert, wodurch die beiden Stoffzuschnitte mittels Unterdruck von oben auf die Auflagefläche gespannt werden. Anschließend wird der eigentliche Nähvorgang ausgelöst, bei dem der auf einem Wagen angeordnete Nähkopf entlang einer Führung am Rand des Auflagetisches entlangfährt und die dort liegenden, miteinander zu verbindenden Kanten der Stoffzuschnitte vernäht.After mutually aligning the fabric blanks the suction pump is activated, causing the two fabric cuts by means of negative pressure from above onto the support surface be excited. Then the real one Sewing process triggered, in which the arranged on a carriage Sewing head along a guide on the edge of the table drives along and the lying there, together sewn edges of the fabric blanks to be connected.
