Bei Kettehstühlen geschieht der Abzug der Ware von den Nadeln auf. den Warenbaum in der bei Textilmaschinen ganz allgemein üblichen Weise, daß der Warenbaum mit einer Riemen- oder Kettenscheibe versehen wird, über die ein an seinem Ende durch ein Gewicht belastetes Zugorgan geschlungen ist. Solange das Gewicht freischwebend an dem Riemen oder der Kette zieht, erfolgtIn the case of chain chairs, the goods are withdrawn from the needles. the goods tree in the manner that is generally customary in textile machines that the goods tree is provided with a belt or chain pulley is looped over which a tensile element loaded by a weight at its end is. As long as the suspended weight pulls on the belt or chain, it takes place

ίο der Warenabzug in gewünschter Weise regelmäßig. Oft kömmt es aber vor, daß die die Maschine bedienende Person vergißt, zur rechten Zeit das Abzugsgewicht wieder emporzudrehen. Wenn daher in diesem Falle das Gewicht auf dem Fußboden auf ruht, so hört der Abzug naturgemäß auf und, da der Kettenstuhl trotzdem weiter arbeitet, so findet ein Verfitzen und vollständiges Verderben der Ware an ihrer Entstehungsstelle, d. h. bei der Nadelreihe, statt.ίο the withdrawal of goods in the desired manner on a regular basis. But it often happens that the person operating the machine forgets to turn the trigger up again at the right time. Therefore, if in this case the weight rests on the floor, the deduction naturally stops and, since the Chain chair continues to work anyway, so there is a mistake and complete ruin of the Goods at their place of origin, d. H. at the row of needles instead.

Diesen Übelstand zu vermeiden, ist die vorliegende Erfindung bestimmt, welche eine vollkommen selbsttätig wirkende Warenabzugseinrichtung zum Gegenstand hat und daher völlig unabhängig von der etwaigen Vergeßlichkeit irgendeiner Person ist.To avoid this inconvenience, the present invention is determined to be which one has as its subject matter a fully automatic goods take-off device and therefore is completely independent of any person's forgetfulness.

Ein Ausführungsbeispiel des Erfindungsgegenstandes zeigt die beiliegende Zeichnung. Fig. ι ist eine Seitenansicht, Fig. 2 eine Vorderansicht derjenigen Teile eine's Kettenstuhles, welche für das Verständnis der Erfindung in Frage kommen.The accompanying drawing shows an exemplary embodiment of the subject matter of the invention. Fig. 1 is a side view, Fig. 2 is a front view those parts of a chain chair which are necessary for the understanding of the invention come into question.

Der Warenbaum 1 ruht drehbar gelagert in den beiden aufrechtstehenden Lagerträgern 2, 3, deren unteres Ende starr befestigt auf der schwingbar gelagerten Welle 4 ruht. Am rechten Ende des Warenbaums 1 ist mit ihm starr verbunden das Schneckenrad 5 angeordnet, welches mit einer Schnecke 6 in Eingriff steht. Letztere ist drehbar gelagert in dem Gehäuse 7, welches selbst um eine feststehende Achse 8 schwingbar gelagert ist, so daß die Schnecke 6 nach Bedarf aus den Zähnen des Schneckenrades 5 ausgehoben und wieder in sie eingesenkt werden kann. Die Schnecke 6 empfängt ihren Antrieb durch Vermittlung der Winkelrädchen 9 und 10, wovon 9 mit der Schnecke 6 auf gemeinsamer Welle 11 befestigt ist, während das Rädchen 10 auf der Welle 8 steckt und durch diese mit der Schnurrolle 12 zu einem starren Ganzen vereinigt ist. In dem Gehäuse 7, welches um die Welle 8 schwingen kann und worin die Schneckenwelle 11 gelagert ist, ist auch ein kleines Exzenter 13 angeordnet. Wenn man dieses mittels eines Handrädchens 14 verdreht, so rückt man damit die Schnecke 6 aus den Zähnen des Schneckenrades 5 aus.The tree 1 rests rotatably mounted in the two upright bearing supports 2, 3, the lower end of which rests on the pivotably mounted shaft 4 in a rigid manner. At the right end of the tree 1, the worm wheel 5 is rigidly connected to it, which with a worm 6 in Engagement is. The latter is rotatably mounted in the housing 7, which itself around a fixed axis 8 is pivotably mounted so that the screw 6 as required from the The teeth of the worm wheel 5 can be excavated and sunk back into them. The worm 6 receives its drive through the mediation of the angular wheels 9 and 10, 9 of which is attached to the screw 6 on a common shaft 11, while the Wheel 10 is stuck on the shaft 8 and through this with the cord roller 12 to a rigid Whole is united. In the housing 7, which can oscillate around the shaft 8 and in which the worm shaft 11 is supported, a small eccentric 13 is also arranged. If you twist this by means of a handwheel 14, you move the Worm 6 from the teeth of the worm wheel 5.

Auf der Hauptantriebswelle 15 des Ketten-Stuhls sitzt die große Schnurrolle 16, von welcher aus die Schnurrolle 12 mittels der Schnur 17 angetrieben wird. Die Schnur läuft außerdem über die Leitrollen 18 und 19. ν Der Lagerträger 20, in welchem die kleine Welle 8 drehbar ruht, bildet mit dem um die Welle 4 schwingbaren Lagerträger 3 ein starres Ganzes, so daß also nicht nur derOn the main drive shaft 15 of the chain chair sits the large line roller 16, from which is driven from the line roller 12 by means of the line 17. The string also runs over the guide rollers 18 and 19. ν The bearing bracket 20, in which the small Shaft 8 rests rotatably, forms a bearing bracket 3, which can swing around shaft 4 rigid whole, so that not only the

Warenbaum ι, but also the small shaft 8 in the arc of a circle around the shaft 4 can carry out an oscillation, even if only a small one. An oscillation in this sense takes place for the purpose of being able to tension the drive cord 17 as required and to be able to loosen it again. If it is tensioned when the tree 1 swings out in the direction of the arrow 21, the friction of the tensioned cord 17 on the circumference of the cord disc 12 causes the entrainment in the direction of the arrow 22, and it then takes place through the intermediary of the angle wheels 10, 9 and the Screw engagement 6, 5 pulling off the item 24 coming from the needles 23 onto the tree 1 instead. The transmission ratio of the angular wheels 10, 9 and the worm drive 6, 5 is chosen so that the removal of the goods is faster than the goods on the needles 23 arise. As a result, while the wheels 5, 6, 9, 10 are working, the whole mechanism, which is swingable about the shaft 4, will straighten up because the tension of the goods 24 pulls it backwards in the direction of the arrow 25. As a result, however, the drive cord 17 becomes loose again and finally begins to slip on the circumference of the disk 12. As a result, the drive of the goods take-off is interrupted, which lasts until enough goods have again been delivered by the needles 23 that the drive cord 17 is tensioned as a result of repeated oscillation of the mechanism in the direction of the arrow. This is followed by the removal of the goods for a few moments, and so the game repeats itself over and over again without the need for the slightest supervision.

Ρλτεντ claim:

Self-acting fabric take-off device for warp knitting chairs, thereby characterized in that the tree of goods transversely to its longitudinal direction from the row of needles (23) mounted so that it can move again and again towards it and with a friction drive is inevitably connected in such a way that when a movement of the goods tree (1) as a result of removal of the goods takes place away from the needles (23), the friction drive (12, 17) of the tree (1) Activated by pressing the rubbing surfaces, but immediately is interrupted again when the goods (24) to be withdrawn are wound onto the goods tree (1) and come closer of the fabric tree after the needles (23) and thus the loosening of the drive friction surfaces takes place again.
