The rotating cutting blade (5) of the cutting attachment, has at least two cutting edges (7), equidistant around the rotating blade axis. The rotating blade (5) has a quadratic plan shape, with four cutting edges (7) along the sides of the quadrilateral.

Description

Die Erfindung bezieht sich auf eine Zusatzvorrichtung für Nähmaschinen zum Beschneiden des Nähgutes mit einem ein Messer und ein Gegenmesser umfassenden Schneidwerkzeug, das in Abhängigkeit vom intermittierenden Nähgutvorschub antreibbar und mit seiner Schneidebene vorschubparallel ausgerichtet ist.The invention relates to an additional device for sewing machines Trimming the material with a knife and a counter knife Cutting tool that depends on the intermittent material feed drivable and aligned with its cutting plane parallel to the feed is.

Um im Zuge eines Nähvorganges das Nähgut ordnungsgemäß in Vorschubrichtung beschneiden zu können, darf das Schneidwerkzeug nur dann zur Wirkung kommen, wenn das Nähgut auf Grund des intermittierenden Vorschubes für den Einstich der Nähnadel stillgehalten wird, wodurch Schoppungen u. dgl. des Nähgutes und damit verbundene Unregelmäßigkeiten des Schnittes verhindert werden. Die Schneidwerkzeuge bestehen deshalb auch bisher durchwegs aus normal zur Vorschubrichtung auf- und abbewegbaren Hubmessern, die mit stehenden Gegenmessern zusammenarbeiten und während eines Vorschubstillstandes gleichzeitig mit einem Nadelhub ihren das Nähgut schneidenden Arbeitshub ausführen, beim Rückhub hingegen das Nähgut für die schrittweise Vorschubbewegung freigeben. Diese Schneidwerkzeuge sind allerdings recht träge und begrenzen die mögliche Nähgeschwindigkeit, sie sind mit einem beträchtlichen Bauaufwand und Platzbedarf verbunden und beeinträchtigen mit ihrem den unteren Gegenmesser zugeordneten, über den Nähtisch hochragenden und hubbewegbaren oberen Hubmessern die Nähgutführung.To properly sew the material in the feed direction during a sewing process To be able to cut, the cutting tool may only be effective come when the sewing material due to the intermittent feed for the Puncture of the sewing needle is kept still, whereby Schoppungen u. The like Sewing material and related irregularities in the cut are prevented become. The cutting tools have therefore consistently been made up to now Lifting knives that can be moved up and down normally to the feed direction standing counter knives work together and during a feed standstill their working stroke cutting the sewing material simultaneously with a needle stroke on the return stroke, however, the material for the gradual feed movement release. However, these cutting tools are quite sluggish and limit the possible sewing speed, they are with a considerable Construction effort and space requirements and interfere with your assigned to the lower counter knife, protruding above the sewing table and stroke movable upper lifting knives the material guide.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Zusatzvorrichtung der eingangs geschilderten Art zu schaffen, die sich durch ihr vergleichsweise einfaches, platzsparendes und in der Schneidgeschwindigkeit auch auf hohe Nähgeschwindigkeiten abstimmbares Schneidwerkzeug auszeichnet.The invention is therefore based on the object of an additional device to create the kind described above, which is characterized by its comparative simple, space-saving and high cutting speed Sewing speeds adjustable cutting tool distinguishes.

Die Erfindung löst diese Aufgabe dadurch, daß das Schneidwerkzeug ein um eine zur Schneidebene normale Drehachse antreibbares Rotationsmesser aufweist, das wenigstens eine sich nur über einen Teil des Messerumfanges erstreckende, in ihrem Verlauf von einem Kreisbogen um die Drehachse abweichende Schneide bildet und mit einer an den Nähgutvorschub indirekt proportional zur Schneidenanzahl angepaßten Drehzahl umläuft. Durch die Ausbildung einer von einem Kreisbogen abweichenden Schneide auf einem Rotationsmesser läßt sich bei einem Zusammenwirken dieser Schneide mit einem geeigneten Gegenmesser ein ziehender, scherenähnlicher Schnitt vorgegebener, durch die Relativbewegung der Messerschneide entlang der Gegenschneide bestimmter Schnittlänge erreichen, wobei das Nähgut auf Grund der Scherwirkung zwischen Messerschneide und Gegenschneide festgehalten wird, dann aber das Nähgut wieder frei beweglich ist und seinen Vorschubschritten unterworfen werden kann. Mit einer auf den Nähvorschub abgestellten, zu den Vorschubschritten synchronisierten Drehzahl kann daher ein Rotationsmesser als Teil des Schneidwerkzeuges eingesetzt werden, das nicht nur zu einer rationellen und aufwandsarmen Konstruktion führt, sondern auch mit praktisch beliebiger Schnittgeschwindigkeit funktionssicher arbeitet. Da für jeden Schnitt eine Messerschneide der Gegenschneide des Gegenmessers entlanggleiten muß, kann die Drehzahl des Rotationsmessers durch die Anzahl der vorhandenen Schneiden in Abhängigkeit vom Vorschub bzw. von der Stichzahl der Nähnadel beeinflußt werden, wobei die Drehzahl mit zunehmender Schneidenanzahl sinkt. Die Schneiden selbst sind vorzugsweise geradlinig, sie könnten aber auch bogenförmig verlaufen, um spezielle Schnittbedingungen zu berücksichtigen, und auch das Gegenmesser kann unterschiedliche, an die Messerschneiden angepaßte Gegenschneiden bilden sowie als festes Gegenmesser, aber auch als gegensinnig zum Rotationsmesser drehendes Gegenmesser vorgesehen sein. Wegen des einfachen neuen Schneidwerkzeugkonzeptes ist es problemlos möglich, das feste Gegenmesser oberhalb und das Rotationsmesser unterhalb des Nähtisches anzuordnen, so daß störende Hindernisse für das Nähgut im Nähtischbereich vermieden sind und die Nähgutführung unbeeinträchtigt bleibt. Auch eine umgekehrte Messer-Gegenmesseranordnung oder ein drehendes Gegenmesser bringt wegen der fehlenden Hubbewegung kaum Schwierigkeiten hinsichtlich der Anordnung im Vorschubbereich des Nähgutes mit sich.The invention solves this problem in that the cutting tool a rotary knife that is drivable to the cutting plane has at least one only over part of the knife circumference extending, deviating in its course from a circular arc around the axis of rotation Cutting edge forms and with a indirectly proportional to the material feed speed adjusted to the number of cutting edges. Through training a cutting edge deviating from a circular arc on a rotary knife can interact with this cutting edge with a suitable one Counter knife a pulling, scissor-like cut specified by which Relative movement of the knife edge along the counter knife certain Reach cutting length, the sewing material between due to the shear effect Knife edge and bedknife is held, but then the sewing material is freely movable again and can be subjected to its feed steps. With a synchronized to the feed steps on the sewing feed Speed can therefore be a rotary knife as part of the cutting tool can be used, not only for a rational and low-effort Construction leads, but also with practically any cutting speed works reliably. As a knife edge for each cut Counter knife of the counter knife must slide along, the speed of the Rotation knife depending on the number of cutting edges available be influenced by the feed or the number of stitches of the sewing needle, the Speed decreases with increasing number of cutting edges. The cutting edges themselves are preferably straight, but they could also run in an arc to to consider special cutting conditions, and also the counter knife can have different counter cutting edges adapted to the knife edges form as well as a fixed counter knife, but also as opposite to the rotary knife rotating counter knife can be provided. Because of the simple new one Cutting tool concept, it is easily possible, the fixed counter knife above and to arrange the rotary knife below the sewing table, see above that disturbing obstacles for the sewing material in the sewing table area are avoided and the sewing material guidance remains unaffected. Also an inverted knife counter knife arrangement or a rotating counter knife brings because of lack of lifting movement hardly any difficulties with regard to the arrangement in the Feed area of the material with itself.

Schneid- und vorschubtechnisch günstige Bedingungen ergeben sich, wenn das Rotationsmesser wenigstens zwei um die Drehachse gleichmäßig verteilt angeordnete Schneiden aufweist. Es entstehen Flügel- oder Scheibenmesser, die symmetriebedingt zu keinen Unwuchten führen und pro Drehzahl der Schneidenanzahl entsprechend viele Schnitte gewährleisten, wodurch ein störungsfreier, schwingungsarmer Betrieb zustande kommt.Favorable conditions in terms of cutting and feed technology arise if that Rotary knife at least two arranged evenly distributed around the axis of rotation Has cutting. There are wing or disc knives that Due to symmetry, do not lead to imbalance and the number of cutting edges per speed ensure a corresponding number of cuts, which ensures a trouble-free, low-vibration operation comes about.

Weist das Rotationsmesser eine quadratische Grundform und vier den Quadratseiten entlang verlaufende Schneiden auf, werden auf rationelle Weise bestens auf einen Nähvorgang abgestimmte Schnittbedingungen hinsichtlich Schneidenführung, Schnittlänge, Schnitt- und Öffnungstakte u. dgl. eingehalten.The rotary knife has a square basic shape and four sides of the square cutting edges running along, are best in a rational way cutting conditions matched to a sewing process with regard to cutting edge guidance, Cutting length, cutting and opening cycles u. The like.

Um in einem Arbeitsgang auf einer Nähmaschine 1 Nähgut nähen und in Vorschubrichtung V Beschneiden zu können, gibt es in Vorschubrichtung vor der Stichplatte 2 des Nähtisches 3 eine Zusatzvorrichtung 4, die ein mit ihrer Schneidebene S vorschubparallel ausgerichtetes Schneidwerkzeug aus einem gegenüber dem Nähtisch 3 unteres, um eine zur Schneidebene S normale Drehachse D antreibbares Rotationsmesser 5 und ein oberes festsitzendes Gegenmesser 6 umfaßt. Das Rotationsmesser 5 weist eine quadratische Grundform auf und bildet vier den Quadratseiten entsprechende Schneiden 7, die mit der Gegenschneide 8 des Gegenmessers 6 zusammenwirken. Das Rotationsmesser 5 steht über eine Messerwelle 9 mit einem nur angedeuteten Getriebe 10 und einer nicht weiter dargestellten Antriebswelle der Nähmaschine 1 in Antriebsverbindung und ist in seiner Drehzahl indirekt proportional zur Schneidenanzahl an den intermittierenden Nähgutvorschub angepaßt, entspricht also beispielsweise dem vierten Teil der Schnittfrequenz des Vorschubes und damit dem vierten Teil der Stichfrequenz der Nähnadel. Durch diese Abstimmung zwischen Messerdrehzahl und intermittierendem Vorschub wird das Nähgut immer nur in der Stillhaltephase für den Nadelstich zwischen Messerschneide 7 und Gegenschneide 8 schneidend festgehalten, während nach jedem Schnitt vor dem Wirksamwerden der folgenden Schneide das Nähgut freigegeben ist und den nächsten Vorschubschritt vorwärtsbewegt werden kann.To sew 1 sewing material in one step on a sewing machine and in the feed direction V To be able to prune is in the feed direction in front of the Throat plate 2 of the sewing table 3 an additional device 4, one with its Cutting plane S cutting tool aligned parallel to feed opposite the sewing table 3 lower, about a normal to the cutting plane S axis of rotation D driven rotary knife 5 and an upper fixed counter knife 6 includes. The rotary knife 5 has a square basic shape and forms four edges 7 corresponding to the square sides, which with the Counter cutting edge 8 of the counter knife 6 cooperate. The rotary knife 5 stands over a knife shaft 9 with a gear 10 and only indicated a drive shaft of the sewing machine 1, not shown, in drive connection and its speed is indirectly proportional to the number of cutting edges adapted the intermittent material feed, so corresponds for example the fourth part of the cutting frequency of the feed and thus the fourth part the stitch frequency of the sewing needle. Through this coordination between knife speed and intermittent feed, the material is only ever in the standstill phase for the needle stitch between knife edge 7 and counter knife 8 held cutting while after each cut before taking effect the following cutting edge the material is released and the next one Feed step can be moved forward.

Es entsteht eine aufwandsarme und platzsparend unterzubringende Zusatzvorrichtung 4, deren Schneidwerkzeug ein funktionssicheres Beschneiden des Nähgutes ohne Beeinträchtigung der Nähgutführung und mit bestens an die möglichen Nähgeschwindigkeiten anpaßbarer Schnittgeschwindigkeit und einwandfreien Schnittbedingungen erlaubt.A low-cost and space-saving additional device is created 4, the cutting tool a reliable trimming of the Sewing material without impairing the guidance of the sewing material and with the best possible sewing speeds, adjustable cutting speed and perfect cutting conditions allowed.
