Description

Die Erfindung bezieht sich auf ein Oberzangenmesser gemäss dem Oberbegriff des Patentanspruchs 1 (siehe z.B. EP-A-0 368 060).The invention relates to an upper pliers knife according to the preamble of claim 1 (see e.g. EP-A-0 368 060).

Uebliche Kämmaschinen enthalten in jedem Kämmkopf ein Zangenaggregat mit einem Zangenrahmen, der eine Unterzangenplatte trägt und in dem ein Speisezylinder gelagert ist, und mit Oberzangenarmen, die mit dem Zangenrahmen schwenkbar verbunden sind und ein Oberzangenmesser tragen. Im Betrieb wird das Zangenaggregat zwischen einer hinteren und einer vorderen Endlage hin- und herbewegt. In der hinteren Endlage drückt der mit einer Faserablenklippe versehene untere Rand des Oberzangenmessers eine Watte, von der ein Faserbart durch einen rotierenden Rundkamm ausgekämmt wird, gegen einen vorderen Rand der Unterzangenplatte.Common combing machines are included in each combing head a pliers unit with a pliers frame, which is a pliers plate carries and in which a feed cylinder is stored and with tongs arms that are connected to the tongs frame are pivotally connected and carry a pair of pliers knives. In operation, the pliers unit is between a rear and a front end position back and forth. In the the rear end position presses with a fiber deflector provided cotton wool bottom edge of the top pliers knife, of which a fiber beard through a rotating circular comb is combed out against a front edge of the pliers plate.

Die Belastung der Teile, welche das Zangenaggregat hin- und herbewegen, ist abhängig von der Zahl der Hin- und Herbewegungen pro Zeiteinheit - Kammspielzahl - und von der Masse des Zangenaggregates. Um die Kammspielzahl erhöhen zu können, ist man bestrebt, die Masse des Zangenaggregates möglichst gering zu halten.The load on the parts that make up the pliers moving back and forth depends on the number of Back and forth movements per unit of time - number of combs - and the mass of the pliers unit. The number of combs to be able to increase the mass of the To keep the pliers aggregate as low as possible.

Im Hinblick auf dieses Ziel besteht die Aufgabe der Erfindung darin, das eingangs angegebene Oberzangenmesser derart auszubilden, dass seine Masse kleiner ist als diejenige von bekannten Oberzangenmessern, dass es aber trotzdem in der Lage ist, eine Watte mit einem Liniendruck der erforderlichen Grösse und Gleichmässigkeit auf eine Unterzangenplatte zu klemmen.The task exists with this aim in mind the invention in the above-mentioned pliers knife trained in such a way that its mass is smaller than that of known pliers knives that it but is still able to print a cotton ball with a line the required size and uniformity to clamp on a pliers plate.

Die Aufgabe wird erfindungsgemäss mit dem im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmal gelöst. Die Ausnehmung bzw. Ausnehmungen führen zu der geforderten Reduktion der Masse der Platte. Da die Ausnehmungen jedoch nur zwischen den beiden Längsrändern der Platte vorgesehen sind, nicht aber im Bereich der Längsränder selbst, kann die Platte trotzdem - ähnlich wie ein T-Balken bzw. C-Balken - eine ausreichende Steifigkeit aufweisen, so dass sie mit ihrem mit der Faserablenklippe versehenen Längsrand den Liniendruck der erforderlichen Grösse und Gleichmässigkeit ausüben kann. Ueberdies besteht die Möglichkeit, die Ausnehmung bzw. Ausnehmungen so auszubilden und anzuordnen, dass die Steifigkeit der Platte im Bereich ihrer Längsmitte höher ist als im Bereich ihrer Enden. Dadurch kann eine weitere Verbesserung der Gleichmässigkeit des von der Platte ausgeübten Liniendrucks erzielt werden.The object is achieved with the im characterizing part of claim 1 specified Feature solved. The recess or recesses lead to the required reduction in the mass of the plate. Since the However, recesses only between the two longitudinal edges the plate are provided, but not in the area of Longitudinal edges themselves, the plate can still - similar to a T-beam or C-beam - sufficient rigidity have so that they with their with the fiber deflecting cliff provided longitudinal edge the line pressure of the required Can exercise size and uniformity. Moreover, there is the possibility of the recess or recesses so train and arrange that the rigidity of the Plate in the area of its longitudinal center is higher than in the area of their ends. This can be a further improvement the uniformity of the line pressure exerted by the plate be achieved.

    • Gemäss Fig. 1 enthält ein Kämmkopf zwei Abreisszylinder 1 und 2, eine Rundkammwelle 3 und eine Zangenwelle 4, die alle in einem nicht dargestellten Maschinengestell gelagert sind. Auf der Zangenwelle 4 sitzen Zangenkurbeln 5, an denen das hintere Ende eines Zangenrahmens 6 angelenkt ist. Das vordere Ende des Zangenrahmens 6 ist an Vorderstützen 7 angelenkt, die um die Achse der Rundkammwelle 3 schwenkbar sind. Der Zangenrahmen 6 trägt eine Unterzangenplatte 8. Ein Oberzangenmesser 9 ist von Oberzangenarmen 10 getragen, die mit dem Zangenrahmen 6 um eine Achse 11 schwenkbar verbunden sind. Im Betrieb wird der Zangenrahmen 6 von der Zangenwelle 4 hin- und herbewegt. In der dargestellten hinteren Endlage des Zangenrahmens 6 drückt der untere Rand des Oberzangenmessers 9 eine Watte W, von der ein Faserbart durch ein auf einer rotierenden Rundkammwalze 12 angeordnetes Rundkammsegment 13 ausgekämmt wird, gegen den vorderen Rand der Unterzangenplatte 8. Am unteren Rand 9.1 des Oberzangenmessers 9 ist, wie aus Fig. 4 zu ersehen ist, eine Faserablenklippe 9.2 ausgebildet, die den auszukämmenden Faserbart in die Benadelung des Rundkammsegmentes 13 lenkt.1, a combing head contains two tear-off cylinders 1 and 2, a round comb shaft 3 and a pliers shaft 4, all in a machine frame, not shown are stored. Pliers cranks are located on the pliers shaft 4 5, on which the rear end of a pliers frame 6 is articulated. The front end of the tong frame 6 is on Front supports 7 articulated about the axis of the round comb shaft 3 are pivotable. The tong frame 6 carries one Lower clamp plate 8. An upper clamp knife 9 is of upper clamp arms 10 worn with the pliers frame 6 around an axis 11 are pivotally connected. In operation the tong frame 6 is moved back and forth by the tong shaft 4. In the illustrated rear end position of the pliers frame 6 presses the lower edge of the top pliers knife 9 Cotton wool, of which a fiber beard by rotating on a Round comb roller 12 arranged round comb segment 13 is combed out against the front edge of the pliers plate 8. At the lower edge 9.1 of the top pliers knife 9, 4, a fiber deflecting cliff 9.2 trained, the to be combed the beard in the Needling the circular comb segment 13 steers.

    Das Oberzangenmesser 9, das in den Fig. 2 bis 4 für sich allein dargestellt ist, besteht aus einer langgestreckten Platte, in der Regel aus Metall, insbesondere Stahl. Um die Masse der Platte zu verringern, enthält diese zwischen dem unteren Längsrand 9.1 und dem diesem gegenüberliegenden oberen Längsrand 9.3 eine Ausnehmung in Form einer in der Rückseitenfläche der Platte ausgebildeten Längsnut 9.4. Die Längsnut 9.4 erstreckt sich mit gleichbleibender Tiefe und gleichbleibender Breite von einem Ende der Platte 9 bis zum anderen Ende, also praktisch über die ganze Länge der Platte.The upper pliers knife 9, which in FIGS. 2 to 4 shown on its own consists of an elongated Plate, usually made of metal, in particular Stole. To reduce the mass of the plate contains this between the lower longitudinal edge 9.1 and this opposite upper longitudinal edge 9.3 a recess in Form one formed in the back surface of the plate Longitudinal groove 9.4. The longitudinal groove 9.4 extends with constant depth and width of one end of the plate 9 to the other end, so practical over the entire length of the plate.

    Damit der untere Rand 9.1 der Platte 9 im Betrieb einen ausreichend gleichförmigen Liniendruck auf die Watte W ausüben kann, kann es wünschbar sein, die zwischen den beiden Längsrändern 9.1 und 9.3 der Platte vorgesehene Ausnehmung so auszubilden, dass die Platte 9 im Bereich ihrer Längsmitte eine höhere Steifigkeit aufweist als im Bereich ihrer Enden. Beispielsweise kann man die Längsnut 9.4 so ausbilden, dass ihre Tiefe und/oder ihre Breite von der Längsmitte der Platte 9 gegen deren Enden hin zunimmt.So that the lower edge 9.1 of the plate 9 in operation a sufficiently uniform line pressure on the cotton W can exercise, it may be desirable to move between the provided both longitudinal edges 9.1 and 9.3 of the plate Form the recess so that the plate 9 in the area their longitudinal center has a higher rigidity than in Area of their ends. For example, you can use the longitudinal groove 9.4 so that their depth and / or width of the longitudinal center of the plate 9 increases towards the ends.

    Als Beispiel zeigen die Fig. 5 bis 7 eine langgestreckte Platte 19 mit einer zwischen dem unteren Längsrand 19.1 und dem oberen Längsrand 19.3 vorgesehenen Längsnut 19.4, die eine von der Längsmitte zu den Enden der Platte hin zunehmende Tiefe aufweist. As an example, FIGS. 5 to 7 show an elongated one Plate 19 with one between the lower longitudinal edge 19.1 and the upper longitudinal edge 19.3 provided Longitudinal groove 19.4, the one from the longitudinal center to the ends the plate has increasing depth.

    Anstelle der beschriebenen Längsnuten, wie den Nuten 9.4 oder 19.4, oder zusätzlich zu denselben, kann eine ein Oberzangenmesser bildende Platte auch andere Ausnehmungen zwischen ihren Längsrändern aufweisen. So zeigt Fig. 8 eine Platte 29, die zwischen ihren Längsrändern 29.1 und 29.3 zwei schlitzförmige Ausnehmungen 29.4 und 29.5 aufweist, welche sich von den beiden Enden der Platte aus je über einen Teil der Länge der Platte erstrecken. Die Schlitze 29.4 und 29.5 verringern nicht nur die Masse der Platte 29, sondern haben auch zur Folge, dass die Steifigkeit der Platte 29 im Bereich ihrer Längsmitte höher ist als bei den Enden im Bereich der Schlitze 29.4 und 29.5.Instead of the described longitudinal grooves, such as the Grooves 9.4 or 19.4, or in addition to the same, can a plate forming an upper knife also others Have recesses between their longitudinal edges. So Fig. 8 shows a plate 29 between its longitudinal edges 29.1 and 29.3 two slot-shaped recesses 29.4 and 29.5, which extends from the two ends of the plate each over part of the length of the plate extend. The slots 29.4 and 29.5 do not narrow only the mass of the plate 29, but also result in that the rigidity of the plate 29 in the area of its longitudinal center is higher than at the ends in the area of the slots 29.4 and 29.5.

    Die Fig. 9 zeigt noch ein Oberzangenmesser in Form einer langgestreckten Platte 39 aus Metall, die zwischen ihren Längsrändern 39.1 und 39.3 von den beiden Enden ausgehende kurze Schlitze 39.4 und 39.5 aufweist. Zusätzlich sind zwischen den Längsrändern 39.1 und 39.3 weitere Ausnehmungen in Form von Durchbrechungen 39.6 vorhanden. Die Formen und Abmessungen der Durchbrechungen 39.6 und ihre Verteilung sind so gewählt, dass die Steifigkeit der Platte 39 im Bereich ihrer Längsmitte höher ist als im Bereich der Enden der Platte. Um der Gefahr zu begegnen, dass sich in den Durchbrechungen 39.6 oder in den Schlitzen 39.4, 39.5 Staub und Faserflug ansammelt, können alle oder einige derselben mit leichtem Füllstoff ausgefüllt sein. Der Füllstoff kann aus einem Kunststoff bestehen, welcher z.B. in die Durchbrechungen eingeschäumt werden kann.Fig. 9 shows an upper pliers knife in Form of an elongated plate 39 made of metal, the between their longitudinal edges 39.1 and 39.3 of the two Outgoing short slots 39.4 and 39.5. In addition, between the longitudinal edges 39.1 and 39.3 further recesses in the form of openings 39.6 available. The shapes and dimensions of the openings 39.6 and their distribution are chosen so that the rigidity the plate 39 higher in the area of its longitudinal center than in the area of the ends of the plate. To the danger encounter that in the openings 39.6 or in the slots 39.4, 39.5 accumulate dust and fiber fly, can all or some of the same with light filler to be filled out. The filler can be made of a plastic which e.g. foamed into the openings can be.
