Description

Gegenstand der Erfindung ist eine Nähmaschine mit einem einstellbaren Kopf-Modul gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a sewing machine with a adjustable head module according to the preamble of Claim 1.

Nähmaschinen mit modularem Aufbau sind bekannt. Sie bestehen üblicherweise aus verschiedenen Baugruppen, welche dezentral gefertigt und anschliessend zusammengebaut werden. Der Zusammenbau der verschiedenen Baugruppen erfordert aufwendige Einstellarbeiten und zudem eine sehr präzise Ausbildung der Verbindungsstellen zwischen den einzelnen Baugruppen. Im weiteren ist die Justierung zwischen der die Nadel tragenden Baugruppe und der den Greifer aufnehmenden Baugruppe schwierig. Eine nicht optimale Einstellung dieser beiden Baugruppen kann zu Fehlstichen und Nadelbrüchen und selbstverständlich zu einer nicht einwandfreien Stichbildung führen.
Eine modular aufgebaute Nähmaschine ist beispielsweise aus der DE-C2-34 21 995 bekannt. Diese umfasst ein Gehäuse mit einer Arbeitsstück-Tragplatte und einem Tragarm, der oberhalb der Arbeitsstück-Tragplatte angeordnet ist. Die Arbeitsstück-Tragplatte nimmt den Greifer und den Arbeitsstück-Vorschubmechanismus auf, im Tragarm ist die Nadelstange, der Drückerfussantrieb und die Fadenspannvorrichtung untergebracht. Im Gehäuse sind der Antriebsmotor, die Antriebswelle und die Antriebselemente, welche die Nadelstange, die Drückerfussstange sowie den Greifer und die Nähguttransportvorrichtung antreiben, eingesetzt. Die Verbindung der drei Baugruppen erfolgt durch Schrauben und - da keine Justiereinrichtungen vorhanden sind - werden an die Genauigkeit in der Fertigung der Verbindungselemente für die drei Baugruppenteile äusserst hohe Anforderungen gestellt. Eine ähnliche Vorrichtung ist aus der US-A 4,590,875 bekannt, wo ebenfalls an ein die Antriebe aufnehmendes Gehäuse am Tragarm eine Baugruppe mit dem Nadelstangen- und dem Stoffdrückerantrieb und darunter eine Baugruppe mit dem Greifer sowie mit dem Nähguttransportmitteln anschraubbar ist. Auch bei dieser Vorrichtung werden an die Präzision der einzelnen Baugruppen äusserst hohe Anforderungen gestellt, da eine Justierung der einzelnen Baugruppen nicht oder nur in geringem Umfange und mit zeitlichem Aufwand möglich ist. Sewing machines with a modular structure are known. They usually consist of different assemblies, which are manufactured decentrally and then assembled. The assembly of the different assemblies requires complex adjustment work and also a very precise formation of the connection points between the individual assemblies. Furthermore, the adjustment between the assembly carrying the needle and the assembly receiving the gripper is difficult. A less than optimal setting of these two assemblies can lead to skipped stitches and needle breaks and, of course, to incorrect stitch formation.
A modular sewing machine is known for example from DE-C2-34 21 995. This comprises a housing with a work piece support plate and a support arm, which is arranged above the work piece support plate. The work piece support plate receives the gripper and the work piece feed mechanism, the needle bar, the presser foot drive and the thread tensioning device are housed in the support arm. The drive motor, the drive shaft and the drive elements which drive the needle bar, the presser foot bar as well as the gripper and the material transport device are inserted in the housing. The three assemblies are connected by screws and - since there are no adjustment devices - extremely high demands are placed on the accuracy in the manufacture of the connecting elements for the three assembly parts. A similar device is known from US-A 4,590,875, where an assembly with the needle bar and the presser drive and also an assembly with the gripper and with the material transport means can also be screwed onto a housing receiving the drives on the support arm. This device also places extremely high demands on the precision of the individual assemblies, since adjustment of the individual assemblies is not possible, or is possible only to a small extent and in a time-consuming manner.

Aufgabe der vorliegenden Erfindung ist die Schaffung einer Nähmaschine mit einem einstellbaren Kopf-Modul, das kostengünstig und unabhängig vom Maschinengehäuse herstellbar und auf letzterem nach dessen Befestigung leicht bezüglich der Greifereinrichtung justierbar ist.The object of the present invention is to create a Sewing machine with an adjustable head module that inexpensive and independent of the machine housing producible and on the latter after its attachment is easily adjustable with respect to the gripper device.

Gelöst wird diese Aufgabe durch eine Nähmaschine gemäss den Merkmalen des Patentanspruchs 1.This task is solved by a sewing machine according to the features of claim 1.

Das erfindungsgemässe Kopf-Modul lässt sich am Maschinenkörper sowohl in Nährichtung als auch quer zu letzterer auf einfache Weise justieren und in der exakt justierten Position arretieren. Die Justierung ermöglicht eine exakte Einstellung von Nadel bezüglich des Greifers, ohne dass die zu verbindenden Maschinenteile oder Baugruppenteile vorab eine zusätzliche Bearbeitung der beispielsweise aus Druckgruss bestehenden Kontaktflächen benötigen; sie können in rohem Zustand zusammengebaut werden. Der Maschinenkörper kann folglich ohne Nachbearbeitung mit der Tragplatte des aus einem ebenfalls nicht nachgearbeiteten Stanz-/Biegeteil bestehenden Kopf-Moduls verbunden werden.The head module according to the invention can be on Machine body both in the sewing direction and across adjust the latter in a simple way and in the exact Lock adjusted position. The adjustment enables an exact setting of the needle with respect to the hook, without the machine parts to be connected or Assembly parts in advance an additional processing of the for example, contact areas made of pressure casting need; they can be assembled in raw condition become. The machine body can therefore without Post-processing with the support plate from one as well not reworked stamped / bent part existing head module get connected.

Die Ausbildung der Antriebsmittel für die Nadelstange 13 und das Greifersystem 7 sind aus dem Stand der Technik bekannt; sie werden folglich nicht näher beschrieben und nur schematisch dargestellt.With reference number 1 in Figure 1 is the machine housing a sewing machine 2 shown in broken lines, which is a machine body 3 at least partially surrounds. The housing 1 can be made of metal or plastic be made. The machine body 3 is preferably made of Die-cast manufactured and carries one inside Drive motor M with drive means 5 for driving a a gripper 7 of the gripper system 8 and overdrive means 9 and 11 for driving the needle bar 13 with the needle 14. The formation of the drive means for the needle bar 13 and the gripper system 7 are from the prior art known; they are therefore not described in detail and only shown schematically.

Am vorderen stirnseitigen Ende 17 des Tragarms 19 der Nähmaschine 2 ist ein Kopf-Modul 21 befestigt, welches die Nadelstange 13, die Nähfussstange 15 und deren Führungen sowie die Lüftungsvorrichtung für die Nähfussstange 15 (nur Hebel 23 sichtbar) enthält.
Dem Kopf-Modul 21 gegenüberliegend kann ein Handrad 25 zum manuellen Bewegen der Nadelstange 13 angeordnet sein. Am vorderen Ende 29 einer Arbeitsstück-Tragplatte 27 ist ein Greifersystem-Modul 31 mit der Stichplatte 33 befestigt.At the front end 17 of the support arm 19 of the sewing machine 2, a head module 21 is attached, which contains the needle bar 13, the presser foot bar 15 and their guides as well as the ventilation device for the presser foot bar 15 (only lever 23 visible).
A handwheel 25 for manually moving the needle bar 13 can be arranged opposite the head module 21. A gripper system module 31 is attached to the throat plate 33 at the front end 29 of a work piece support plate 27.

Das Kopf-Modul 21, in den Figuren 2,3 und 5 vergrössert dargestellt, umfasst eine Tragplatte 35, welche als Stanz/Biegeteil konzipiert ist, und die notwendigen Ausnehmungen und Bohrungen zur Führung von Maschinenteilen und für deren Befestigung enthält. Die Tragplatte 35 hat im wesentlichen eine L-förmige Gestalt mit einem oberen horizontal verlaufenden ersten Schenkel 37 und einem vertikal verlaufenden zweiten Schenkel 39. Am horizontalen ersten Schenkel 37 sind zwei horizontal verlaufende, nach aussen gerichtete Sicken 41 ausgebildet. Im zentralen Teil der Sicken 41 ist ein, die Sicken 41 in zwei Abschnitte trennendes, Langloch 43 angebracht, durch welches je eine Schraube 45 in Gewindebohrungen 47 am Maschinenkörper 3 eindrehbar ist. Im vertikalen Schenkel 39 ist eine weitere vertikal verlaufenden Ausnehmung 48 ausgestanzt, durch welche der Nähfusslüfterhebel 23 hindurchführbar ist. Seitlich der Ausnehmung 48 ist eine Gewindebohrung 49 ausgebildet, in welche eine Justierschraube 51 eindrehbar ist, die am Maschinenkörper 3 in einer Bohrung 59 gehalten ist. The head module 21, enlarged in FIGS. 2, 3 and 5 shown, comprises a support plate 35, which as a stamped / bent part is designed and necessary Recesses and bores for guiding machine parts and contains for their attachment. The support plate 35 has essentially an L-shaped shape with an upper one horizontally extending first leg 37 and one vertical second leg 39. On the horizontal first legs 37 are two horizontally extending, after beads 41 formed on the outside. In the central part the beads 41 is one, the beads 41 in two sections separating, elongated hole 43 attached, through which one Screw 45 in threaded holes 47 on the machine body 3 can be screwed in. In the vertical leg 39 is another vertically extending recess 48 punched out which the presser foot lifting lever 23 can be passed through. A threaded bore 49 is located to the side of the recess 48 formed, into which an adjusting screw 51 can be screwed which is held on the machine body 3 in a bore 59 is.

Zwischen den beiden Sickenpaaren 41 kann ein weiterer vertikal verlaufender Schlitz 53 in der Tragplatte 35 ausgebildet sein, in welchen der Kopf eines Exzenterstifts 55 eingreift, welcher in einer Bohrung 57 im Maschinenkörper 3 drehbar gelagert ist. Durch Drehen des Exzenterstifts 55 kann das Kopf-Modul 21 in Richtung der Pfeile B justiert werden.
Am Maschinenkörper 3, von dem in Figur 4 nur die Vorderseite 4 und ein Teil der Deckfläche 6 sichtbar sind, sind seitlich der beiden Gewindebohrungen 47 für die Schrauben 45 Rippen 61 ausgebildet, welche von hinten in die Sicken 41 einzugreifen bestimmt sind, wenn das Kopf-Modul 21 am Maschinenkörper 3 befestigt ist.A further vertically extending slot 53 can be formed in the support plate 35 between the two pairs of beads 41, in which the head of an eccentric pin 55 engages, which is rotatably mounted in a bore 57 in the machine body 3. By turning the eccentric pin 55, the head module 21 can be adjusted in the direction of the arrows B.
On the machine body 3, of which only the front 4 and part of the top surface 6 are visible in FIG. 4, ribs 61 are formed on the side of the two threaded bores 47 for the screws 45, which ribs are intended to engage in the beads 41 from behind when the head -Module 21 is attached to the machine body 3.

In der Frontansicht des Kopf-Moduls 21 gemäss Figur 5, auf der auch der Maschinenkörper 3 sichtbar ist, ist oben ein Querschnitt durch eine der Sicken 41 veranschaulicht, in welcher von hinten der Scheitel der Rippe 61 eingreift. Die Tragplatte 35 liegt folglich nur auf dem Scheitel der Rippe 61 am Maschinenkörper 3 an. Der Scheitel der Rippe 61 bildet somit ein Schwenklager, um das das Kopf-Modul 21 durch die Justierschraube 51 in Richtung der Pfeile A schwenkbar ist. Die Befestigungsschrauben 45 halten dabei die Tragplatte 35 anfänglich mit geringem Auflagedruck auf den Rippen 61 fest. Auf dem zweiten Schenkel 39 der Tragplatte 35 greift die Justierschraube 51 in die Gewindebohrung 49 an der Tragplatte 35 ein. Eine Feder 63, deren eines Ende an der Rückseite der Tragplatte 35 aufliegt und deren anderes Ende am Maschinenkörper 3 abgestützt ist, drückt die Tragplatte 35 vom Maschinenkörper weg. Die Schraubenfeder 63 ist vorzugsweise auf dem Schraubenschaft der Justierschraube 51 aufgesetzt. Um der Feder 63 axial genügend Raum zu bieten, kann der Maschinenkörper 3 im Bereich der Führungsbohrung 59 für die Justierschraube 51 mit einer Vertiefung 65 versehen sein.In the front view of the head module 21 according to FIG which is also the machine body 3 is visible at the top Cross section through one of the beads 41 illustrated in FIG which engages the apex of the rib 61 from behind. The support plate 35 is therefore only on the apex of the Rib 61 on the machine body 3. The vertex of the rib 61 thus forms a pivot bearing around which the head module 21 by adjusting screw 51 in the direction of arrows A is pivotable. The fastening screws 45 hold the support plate 35 initially with low contact pressure the ribs 61 firmly. On the second leg 39 the Support plate 35 engages the adjusting screw 51 in the Threaded bore 49 on the support plate 35. A spring 63, one end of which is at the rear of the support plate 35 rests and the other end of it on the machine body 3 is supported, presses the support plate 35 from Machine body away. The coil spring 63 is preferably on the screw shaft of the adjusting screw 51 put on. Enough space around the spring 63 axially offer, the machine body 3 in the area of Guide bore 59 for the adjusting screw 51 with a Depression 65 may be provided.

Im folgenden wird die Montage des Kopf-Moduls 21 am Tragarm 19 erläutert. Die Tragplatte 35 wird mit den beiden Schrauben 45 mit dem Tragarm 19 verbunden, ohne die Schrauben 45 von Anfang an festzuziehen. Gleichzeitig wird die Justierschraube 51 in die Gewindebohrung 49 an der Tragplatte 35 eingedreht. Mit der Exzenterschraube 55 erfolgt nun die Justierung des Kopf-Moduls 21 quer zur Nährichtung (Pfeile B) und anschliessend mit der Justierschraube 51 in Nährichtung (Pfeile A). Sobald die Lage des Kopf-Moduls 21 bzw. der Nadel 14 bezüglich des Greifersystems 7 exakt festgelegt ist, werden die beiden Befestigungsschrauben 45 angezogen. Auf diese Weise lässt sich das Kopf-Modul 21 bzw. die Nadel 14 mit einer Genauigkeit von Hundertstel-Millimetern justieren.In the following, the assembly of the head module 21 on Support arm 19 explained. The support plate 35 is with the two screws 45 connected to the support arm 19 without the Tighten screws 45 from the start. At the same time the adjusting screw 51 in the threaded bore 49 on the Support plate 35 screwed in. With the eccentric screw 55 the head module 21 is now adjusted transversely to Sewing direction (arrows B) and then with the Adjusting screw 51 in the sewing direction (arrows A). As soon as the Location of the head module 21 or the needle 14 with respect to the Gripper system 7 is precisely defined, the two Fastening screws 45 tightened. That way the head module 21 or the needle 14 with a Adjust the accuracy of hundredths of a millimeter.
