Description
Vorrichtung zum pneumatischen Suchen des Fadenendes auf einer sich bildenden Spule bei automatischen Spulmaschinen Die Erfindung betrifft eine Vorrichtung zum pneumatischen Suchen des Fadenendes auf einer sich bildenden Spule bei automatischen Spulmaschinen mit Hilfe eines in Richtung zur Spuloberfläche mündenden unbeweglichen Absaugrohres0 Bei automatischen Kettspulmaschinen ist es im Falle eines Fadenbruches oder eines Abapulens des Kopses notwendig, das Fadenende auf der sich bildenden Spule zu suchen und dieses zum Knotenbinder zu bringen, Zu diesem Zweck wird ein AbZ saugrohr benützt, welches an einen Zentralkanal angeschlossen ist, der in Richtung zur Spuloberfläche mündet und in dem Unterdruck herrscht. Kommt es zum Fadenbruch oder zur Abspulung des Kopses, so wird die sich bildende Spule durch den Impuls eines Fadenwächters in langsame Umdrehungs gebracht, die im entgegengesetzten Sinne zu den beim Spuivorgang üblichen Umdrehungssinn verlaufen. Gleichzeitig wird ein Absaugrohr in Tätigkeit gesetzt, welches das eine Fadenende unter Einwirkung des Unterdruckes auf der sich bildenden Spule sucht und zum Knotenbildner bringt. Diesem legen gleichzeitig andere Organe auch das andere Fadenende vom Kops vor, wonach es zum Zusammenbinden oder Verknüpfen beider loser Fadenenden und zum nachfolgenden Spulen kommt. Dies alles ist bereits bekannt. Dabei zstdas Absaugrohr unbeweglich, denn eine schwenkbare Ausführung des Absaugrohres ist wesentlich komplizierter. Weil es zu Fadenbrüchen, gegebenenfalls zum Abspulen der Kopse während des Spulens von Kettspulen, das ist während der Wickelbildung vom kleinsten bis um größten Durchmesser kommt, ist bei unveränderlicher Lage des Absaugrohres dessen Wirkung bei kleinem Durchmesser der sich bildenden Spule geringer und erhöht sich erst mit wachsendem Spulendurchmesser.Device for the pneumatic search of the thread end on one forming bobbin in automatic winding machines The invention relates to an apparatus for the pneumatic search of the thread end on a forming bobbin with automatic Winding machines with the help of an unmovable opening in the direction of the winding surface Absaugrohres0 With automatic warp winding machines it is in the case of a thread break or Abapulens the cop necessary, the thread end on the forming To find a coil and bring it to the knot, a AbZ uses a suction pipe, which is connected to a central duct that runs in the direction of opens to the bobbin surface and prevails in the negative pressure. If the thread breaks or to unwind the cop, the coil that forms is caused by the impulse of a thread monitor in slow rotation, which in the opposite sense to the usual ones in the case of the haulage process Sense of rotation. Simultaneously a suction tube is put into action, which acts on one end of the thread of the negative pressure on the spool that is being formed and brings it to the knot former. At the same time, other organs also present the other end of the thread from the head to this, after which it is for tying or tying both loose thread ends and for the subsequent one Bobbins is coming. All of this is already known. The suction tube is immobile, because a swiveling design of the suction tube is much more complicated. Because it leads to thread breaks, possibly to the unwinding of the bobbin during winding of warp bobbins, that is during the lap formation from the smallest to the largest diameter comes, if the position of the suction pipe remains unchanged, its effect is small The diameter of the coil being formed is smaller and only increases as it increases Spool diameter.
Die vorliegende Erfindung vermeidet diese Nachteile. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, nit einfachen Mitteln eine gleich große Saugwirkung auf die sich bildende Spule ohne Rücksicht auf den sich bildenden Spulendurchmesser 4U erreichen.The present invention avoids these disadvantages. The present The invention is based on the object of providing an equally large suction effect with simple means on the coil being formed regardless of the coil diameter being formed Reach 4U.
Das Hauptmerkmal der vorliegenden Erfindung besteht darin, daß auf der Mündung eines Absaugrohres ein Ansatz angeordnet ist, welcher mit dem abklappbaren Halter der sich bildenden Spule beweglich verbunden ist.The main feature of the present invention is that on the mouth of a suction tube is arranged an approach, which with the hinged Holder of the forming coil is movably connected.
Ein Ausführungsbeispiel der vorliegenden Erfindung ist schematisch auf den beiliegenden Zeichnungen dargestellt0 Es zeigen: Fig. 1 - eine Seitenansicht der sich bildenden Spule von kleinem Durchmesser, Fig. 2 - eine Seitenansicht der sich bildenden Spule von großem Durchmesser und Fig. 5-eine Draufsicht auf die Vorrichtung der Fig. 1 und 2.An embodiment of the present invention is schematic shown in the accompanying drawings: Fig. 1 - a side view of the small diameter coil forming, Fig. 2 is a side view of the large diameter coil forming; and Fig. 5 is a plan view of the device of FIGS. 1 and 2.
Ein abklappbarer Halter 1 einer sich bildenden Spule 2 ist schwenkbar in Lagern 3 des Maschinenrahmens 4 angeordnet und mit einem Hebel 5 versehen, welcher mit Hilfe einer Zugstange 6 mit einem Arm 7 eines um einen Zapfen 8 eines Absaugrohres 9 schwenkbar gelagerten doppelarmigen Hebels verbunden ist.A retractable holder 1 of a spool 2 that is being formed can be pivoted arranged in bearings 3 of the machine frame 4 and provided with a lever 5, which with the help of a pull rod 6 with an arm 7 of a pin 8 of a suction pipe 9 pivotally mounted double-armed lever is connected.
Der andere Arm 10 dieses doppelarmigen Hebels ist mit einem Zapfen 11 eines Ansatzes 12 gelenkig verbunden. Mit einem weiteren Zapfen 13 des Ansatzes 12 ist ein Arm 14 gelenkig verbunden, welcher um einen Zapfen 15 des Absaugrohres 9 schwenk~ bar gelagert ist. Der Ansatz 12 hat beim gegebenen Ausführungsbeispiel die Form einer Leiste, welche den Raum zwischen der sich bildenden Spule 2 und der oberen Wand 16 des Äbsaugrohres 9 verdeckt und damit sozusagen die obere Wand 16 in ihrer Länge variabel und an den Spulendurchmesser anpaßbar macht. Die untere Wand des Absaugrohres 9 reicht in unveränderbarer Länge in den Zwischenraum zwischen die sich bildende Spule 2 und Fadenführungstrommel 17. Der Ansatz 12 bildet mit den Armen 10 und 14 ein Parallelogramm, welches die gleichlaufende Lage des Ansatzes 12 mit der Bgntellinie A-D der sich bildenden Spule 2 sichert.The other arm 10 of this double-armed lever is with a pin 11 of an approach 12 articulated. With another pin 13 of the approach 12, an arm 14 is articulated, which around a pin 15 of the suction tube 9 is pivotable. The approach 12 has in the given embodiment the shape of a bar, which the space between the forming coil 2 and the The upper wall 16 of the suction tube 9 is covered, and thus the upper wall 16, so to speak makes variable in length and adaptable to the coil diameter. The lower one The wall of the suction pipe 9 extends in an unchangeable length into the space between the forming bobbin 2 and thread guide drum 17. The extension 12 forms with the arms 10 and 14 a parallelogram, which the parallel position of the approach 12 with the Bgntellinie A-D of the forming Coil 2 secures.
Es ist selbstverständlich, daß bei einem weiteren Ausführungsbeispiel gemäß der Erfindung zur Übertragung der Bewegung des Halters 1 auf den Ansatz 12 andere geeignete Mittel verwendet werden können und daß auch der Ansatz 12 eine andere passende Form haben kann.It goes without saying that in a further embodiment according to the invention for transmitting the movement of the holder 1 to the extension 12 other suitable means can be used and that also the approach 12 a may have other suitable shape.
Vergrößert sich während des Spulvorganges der Durchmesser der sich bildenden Spule 2, welche bekannterweise mit Hilfe einer Leit- oder Fadenführungstrommel 17 angetrieben ist, wird der abklappbare Halter 1 in Richtung nach oben ausgeschwenkt. Diese Bewegung wird mittels der bereits angeführten Organe 52 6, 7, 10 und 14 auf den Ansatz 12 derart überführt, daß sich die wirksame Mündung des Absaugrohres 9, welches teilweise oder gänzlich durch den Absatz 12 gebildet wird, in konstanter Entfernung von der sich bildenden Spule 2 befindet und gegenüber den Spulenmantel in wesentlichen eine parallele Lage einnimmtThe diameter of the itself increases during the winding process forming coil 2, which is known with the help of a guide or thread guide drum 17 is driven, the foldable holder 1 is pivoted in the upward direction. This movement is carried out by means of the organs 52 6, 7, 10 and 14 already mentioned the approach 12 transferred in such a way that the effective mouth of the suction tube 9, which is partially or entirely formed by paragraph 12, in constant Distance from the forming coil 2 is located and opposite the coil jacket essentially occupies a parallel position
