Die Zangen der Heilmannschen Kämmaschinen erhalten bisher zwei Arten von Bewegungen. Entweder bleibt die Zange dicht neben der Kämmtrommel während der Kämmperiode unbeweglich stehen, bewegt sich dann zu den Abzugswalzen, um daselbst während der Abzugsperiode wieder in der geeigneten Lage stehenzubleiben, und bewegt sich dann zu der Kämmtrommel zurück, oder bei der anderen Bewegungsart wird die Zange ununterbrochen zwischen der Kämmstelle und den Abzugswalzen mit Hilfe einer Kurbel, eines Exzenters oder einer Kurvenscheibe hin und her bewegt. Bei der erstgenannten unterbrochenen Bewegungsart der Zange spielt die von der Zange durchlaufene Bahn zwischen den beiden festen Lagen keine besondere Rolle. In dem zweiten Falle aber ist der von der Zange durchlaufene Weg von großer Bedeutung und war bisher eine gerade Linie oder ein Kreisbogen oder annähernd eines von beiden. The tongs of Heilmann's combing machines have so far received two types of movements. Either the tongs remain immovable close to the combing drum during the combing period and then move towards the Take-off rollers to be in the appropriate position again during the take-off period stop and then move back to the combing drum, or the other The type of movement is uninterrupted between the combing point and the take-off rollers with the help of a crank, one Eccentric or a cam moves back and forth. In the case of the former, interrupted The type of movement of the tongs does not play a special role in the path traversed by the tongs between the two fixed positions. In the second case, however, the path taken by the forceps is of great importance and so far it has been a straight line or an arc of a circle or approximately one of both.

In den schematischen Fig. ι und 2 der Zeichnung stellt A einen Teil der Kämmtrommel dar. Mit 9 ist eine der Abzugswalzen bezeichnet, während C die Kämmstelle und D die Abzugsstelle darstellen. Die Zange bewegt sich von der Kämmstelle C zur Abzugsstelle D entweder in der aus Fig. 1 ersichtlichen geradlinigen Bahn C, D oder in der aus Fig. 2 ersichtlichen Kreisbogenbahn C, D. In beiden Fällen ist die Zangenbahn eine solche, daß die Zange sich während der Kämmperiode nicht in einer gleichbleibenden Entfernung von den Trommelnadeln befindet, wenn die Zange das hintere Ende ihrer Bahn in der Nähe der Stelle C durchläuft. Außerdem ist die Länge der von der Zange durchlaufenen Bahn beträchtlich, da-sie von den Durchmessern der Kämmtrommel und der Abzugswalzen bestimmt wird.In the schematic FIGS. 1 and 2 of the drawing, A represents part of the combing drum. 9 is one of the take-off rollers, while C represents the combing point and D the take-off point. The forceps moves from the Kämmstelle C for withdrawal point D, either in the manner shown in Fig. 1 rectilinear path C, D or in the manner shown in Fig. 2 arcuate path C, D. In both cases, the pliers web is such that the clamp is is not at a constant distance from the drum needles during the combing period when the tongs pass through the rear end of their path near point C. In addition, the length of the path traversed by the tongs is considerable, since it is determined by the diameters of the combing drum and the take-off rollers.

Der Hauptzweck der vorliegenden Erfindung besteht darin, die von der schweren Zange zu durchlaufende Bahn abzukürzen und sie für ihre Arbeit zweckentsprechender zu gestalten. Die Bahn kann viel kürzer gemacht werden als die geradlinige oder kurvenförmige Bahn C, D (Fig. 1 und 2), und außerdem kann die Zange an der Kämmstelle C in gleichbleibender Entfernung von den Nadeln gehalten werden.The main purpose of the present invention is to shorten the path to be traversed by the heavy tongs and to make it more suitable for its work. The path can be made much shorter than the straight or curved path C, D (Figs. 1 and 2), and in addition the forceps can be held at the combing point C at a constant distance from the needles.

Gemäß vorliegender Erfindung ist die Lagerung des Zangengestelles der Heilmannschen Kämmaschine mit ununterbrochen schwingender Zange unabhängig von der Schwingung selbsttätig veränderlich eingerichtet, um durch eine mit der Schwingung gleichzeitig bewirkte Änderung der Höhenlage des Gestelles die Zangenklemmstelle zwischen den Kämm- und Abzugsöffnungen in jeder gewünschten Bahn hin und her führ,en zu können. Das Zangengestell wird von einer feststehenden, den gewünschten Höhenlagen entsprechend gestalteten Führung und außerdem von einem beliebig schwingbaren Gelenkhebel getragen.According to the present invention, the mounting of the tong frame is Heilmann's Combing machine with continuously oscillating tongs independently of the oscillation set up to be changeable to by a change in the height of the frame caused by the vibration at the same time Pliers clamping point between the combing and take-off openings in any desired path to be able to lead back and forth. The tong frame is made of a fixed, the desired Heights appropriately designed guide and also carried by any pivotable articulated lever.

Claims

Fig. 6 schematically illustrates a particularly advantageous path for the pincer point. In Fig. 3, one end of the tong frame ι is hinged to a pin 2, the is attached to a lever 3 adjustable within certain limits on the shaft 4. The wave 4 is in the usual way by a crank, an eccentric or a cam in the back and oscillation set. Near the other end of the tong frame is a Pin 5 is provided, which is used to carry a ball 6, and around the also for the upper jaw provided tong arm 7 can swing out.

A guide 8, on which the ball 6 runs when the tongs move back and forth. The guide 8 could also be immovable it is clear in which case the ball 6 would have to be adjustable to the pincer point to be able to adjust at the correct distance from the cylinder needles. Possibly the underside of the frame could also be designed accordingly and on an adjustable ball carried by the machine frame as it moves back and forth on rest.

The guide 8 can be given any desired shape, so that the pincer point through the guide can be forced in conjunction with the movement of the pivot 2, to go through any desired path. For example, the pincer point can be the one shown in FIG dotted trajectory, in the rear part of which it corresponds to the circumference of the Combing drum follows, while he is more or less immediately at the front end of the web is guided to the point of contact of the take-off rollers 9 and 10. In this way can be the entire, between the combing and take-off points of the guided back and forth Pliers traversed path can be significantly reduced.

Fig. 4 shows another guide for the pincer point. There is a joint on pin 5 here 11 attached, which by pivot pin 12 with a lever 13 of a shaft 14 is connected in the required manner is set in reciprocation so that in conjunction with the reciprocating motion of the frame 1, the pincer point moves back and forth in any desired path can be.

If you want to let the pincer point follow the circumference of the combing drum during the entire length of the path traversed by it, this can be done in the manner shown in FIG Can wear joint 15, which can also be swung out about pin 16 with the same radius of lever 3. If the pincer point is then perpendicularly above the center point of the combing drum, while at the same time the center points of 5 and 2 are perpendicularly above the center points of 16 and 4, then the pincer point will describe a path c, d running concentrically to the combing drum.

The upper tong arm 7 (Fig. 3) carries a pin 17 which extends from the slotted end the rod 18 is encompassed. The latter carries an adjustable finger 19 through which the slot provided on the upper part, the rod 20 freely engages therethrough. This pole 20 is articulated to the rod 21 attached to the machine frame. Between the finger 19 and the rod 21, the rod 20 is surrounded by a helical spring 22, and at the rear of the rod 18 an adjustable stop 23 is provided.

If the frame 1 moves to the right and takes its arm 7 with it, then as soon as the pliers are closed, the stop 23 is moved away from the rear rod 21 and the spring 22 is compressed, 'whereby the pliers jaws are pressed firmly together. On the other hand, if the frame 1 moves to the left, and the stop 23 is against the rods 21 come to rest, then the upper end of the pin 17 supporting Arm held while the pin 5 is moved further through the frame, as a result, the pliers will open. The pressure exerted by the spring 22 against the finger 19 holds the rod 18 firmly on the pin 17, but allows easy lifting of the Rod 18 from arm 7 when you swing the whole pliers backwards wants to have free access to the needle segments of the combing drum from above.

For the sake of simplicity, the pricking comb, which can be swung out around pin 24, and the feed roller, all of which are of the usual type, are not shown. the individual machine parts can be designed differently, without deviating from the essence of the Invention deviate; in particular one could guide the pliers in any Bahn use other means, or the end of the tong frame remote from the tong point could be used in another Way, as indicated in the drawing, be carried and made to swing.
