Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Zungenöffnung an Strickvorrichtungen, kurz Verfahren und Vorrichtung genannt.The The invention relates to a method and a device for tongue opening Knitting devices, short called method and device.
Stand der Technik:State of the art:
Bei Strickvorrichtungen müssen die Zungen der Nadeln stets geöffnet sein, damit ein Faden eingelegt werden kann. Insbesondere während des Ingangsetzens und auch während des stationären Betriebes und einer möglichen Störung ergibt sich das Problem, die Zungen offen zu halten.at Knitting devices need the tongues of the needles always open so that a thread can be inserted. Especially during the Starting and also while of the stationary Operation and possible disorder the problem arises of keeping the tongues open.
Es sind mehrere Lösungen bekannt geworden. Bei langsam laufenden Strickvorrichtungen wie beispielsweise Flachstrickmaschinen werden die Zungen durch pinselartige Gebilde aufgestoßen.It are several solutions known. For slow running knitting devices such as Flat knitting machines become the tongues by brush-like structures pushed.
Bei schneller laufenden Strickvorrichtungen kommen mechanisch wirkende Zungeöffner mit Haken zum Einsatz, welche die Zungen durch Eingriff im Bereich im Bereich des Nadelkopfes öffnen.at faster running knitting devices come mechanically acting Zungeöffner used with hooks which engage the tongues in the area open in the area of the needle head.
Es ist weiter bekannt geworden, die Zungen durch Preßluft aufzublasen.It is further known to inflate the tongues by compressed air.
Kritik am Stand der Technik:Criticism of the state of the art:
Die Öffnung der Zungen mit pinselartigen Gebilden versagt bei höheren Arbeitsgeschwindigkeiten. Der Verschleiß ist hoch und die baulichen Gegebenheiten bei Strickvorrichtungen mit einer hohen Systemzahl sind für dies Lösung nicht geeignet.The opening of the Tongues with brush-like formations fail at higher working speeds. The wear is high and the structural conditions in knitting with a high number of systems are for this solution not suitable.
Zungenöffner welche die Zungen durch einen Haken öffnen funktinonieren weitgehend ausreichend, greifen aber die Zungen an. Das kann zu Folgebrüchen an den Nadeln führen. So beschränkt man sich in der Praxis auf einige am Umfang angebrachte Zungenöffner.Tongue opener which open the tongues with a hook funktinonieren largely sufficient, but attack the tongues. This can lead to subsequent breaks lead to the needles. So limited in practice, on some circumferentially attached tongue openers.
Die Zungenöffnung durch Preßluft ist sehr wirkungsvoll, aber im Betrieb zu teuer. Da das Ereignis „Zungenöffnen" sehr selten ist, konnte sich die Preßluftmethode nicht durchsetzen.The latch opening by compressed air is very effective, but too expensive in operation. Because the event "opening the tongue" is very rare, could the compressed air method do not enforce.
Aufgabe:Task:
Die Erfindung hat sich die Aufgabe gestellt ein Verfahren und eine Vorrichtung vorzuschlagen, welche berührungslos und energetisch günstig eine Zungenöffnung bewirkt, die so preisgünstig herstellbar ist, daß sie an jeder Strickstelle installiert werden kann.The Invention has the object of a method and an apparatus to propose which contactless and energetically favorable a tongue opening causes, the so cheap it can be produced that they can be installed at every knitting point.
Zweck:Purpose:
Die Erfindung dient dem Zweck der Zungenöffnung beim Anafahren des Strickvorganges und während des stationären Betriebes.The Invention serves the purpose of the tongue opening when Anafahren the knitting process and while of the stationary Operation.
Am ansteigenden Ast der Nadelkurve zwischen dem tiefsetn Punkt und dem Fadenführer wird ein Magnetfeld angelegt. Die Zungen aus magnetischem Material durchlaufen das Magnetfeld und richten sich an den Feldlinien aus, was die Öffnung bewirkt.At the rising branch of the needle curve between the deepset point and the thread guide a magnetic field is applied. The tongues of magnetic material go through the magnetic field and align with the field lines, what the opening causes.
Um die Öffnungswirkung zu verstärken wird vorzugsweise nur die Zunge aus magentischem material gefertigt. Die umliegenden Bauteile sind unmagnetisch.Around the opening effect to reinforce Preferably, only the tongue is made of magentic material. The surrounding components are non-magnetic.
Eine besondere Ausführung besteht darin, im Berührungsbereich der Zunge mit einem Nadelhaken ein unmagnetisches Material an der Zunge, am Nadelhaken oder an beiden Bauteilen anzuornden. Dadurch wird der Magnetfluß zwischen der Zunge und Nadelhaken unterbrochen, wodurch die Öffnungssicherheit steigt.A special design is in the touch area the tongue with a needle hook a non-magnetic material at the Tongue, needle hook or on both components anzuornden. Thereby the magnetic flux is between the tongue and needle hooks are interrupted, thereby increasing the opening increases.
