Description

Bekanntlich wird bei der Verwendung von sogenannten Konusschermaschinen - die zu scherende Kette in eine Anzahl Bänder geteilt und diese Bänder werden nebeneinander auf die Schertrommel aufgewickelt. Das Aufwikkeln der Bänder geschieht zur Verhinderung des Abfallens der einzelnen Schichten eines Bandes in Parallelogrammform, wobei das erste Band sich mit seiner einen schrägen Seite an die schräge Fläche der Schertrommel anlegt. Von dem ersten genauen Scheren des ersten Bandes hängt naturgemäß die gleichmäßige Spannung der. Kettfäden auf den Webebaum zum Teil ab.It is known that when using so-called cone shearing machines - the too The shearing chain is divided into a number of ribbons and these ribbons are placed next to each other wound the shear drum. The winding of the tapes is done for prevention of the falling off of the individual layers of a strip in the form of a parallelogram, whereby the the first band is attached to the inclined surface of the shear drum with one inclined side applies. The uniform shear of the first band naturally depends on the first precise shearing Tension the. Part of the warp threads on the loom.

!5 Bei den Schermaschinen der vorgenannten Art geschieht das Verlegen der einzelnen Schichten durch einen Scherkamm, der mittels zwangläufigen Antriebes von der Schermaschine seitlich verschoben wird. Wenn sich nun hierbei der Scherkamm allzu schnell nach der Seite — beispielsweise nach rechts — bewegt, so findet rechts an der Schräge der Schertrommel ein Anstauen der Kettfäden statt, was zur Folge hat, daß die einzelnen Schichten nicht mehr parallel zur Schertrommel liegen und infolge des größeren Durchmessers die rechts liegenden Kettfäden eine größere Länge haben, wodurch die Kette ungleichmäßig geschoren wird.! 5 With the clippers of the aforementioned Art happens the laying of the individual layers by a shaving comb, which means inevitable drive is shifted laterally by the shearing machine. If now move the shaving comb too quickly to the side - for example to the right - so there is a damming of the warp threads on the right side of the incline of the shear drum, with the result that the individual Layers no longer lie parallel to the shear drum and due to the larger diameter the warp threads on the right are longer, which makes the warp uneven is sheared.

Die veränderte Lage der Kettfädenschichten ist beispielsweise in Fig. 1 strichpunktiert angedeutet. The changed position of the warp thread layers is indicated by dash-dotted lines in FIG. 1, for example.

Um diesen beim Scheren von Kettfäden auftretenden Übelstand zu umgehen, ist man bisher immer nur auf die Geschicklichkeit und Gewissenhaftigkeit des Arbeiters angewiesen.In order to avoid this inconvenience that occurs when shearing warp threads, one is hitherto only dependent on the skill and conscientiousness of the worker.

; Um sich nun von dieser Geschicklichkeit und Gewissenhaftigkeit des Arbeiters unabhängig zu machen, gleichzeitig after den aus der unrichtigen Lage der Fäderischichten herrührenden Fehler schon im Augenblick seines Entstehens kenntlich zu machen, soll die 'den Gegenstand der Erfindung bildende Anzeige- \Orrichtung dienen, die vollkommen selbständig das genaue Scheren der Kette angibt.; To get away from this skill and Conscientiousness of the worker to make independent, at the same time after the wrong Position of the federic layers already originating in the moment of its occurrence to make identifiable, should the 'the subject of the invention display \ Orrichtung who serve completely independently indicates the exact shear of the chain.

Das Neue und Eigentümliche der Anzeigevorrichtung gemäß der Erfindung besteht darin, daß zwei an räumlich voneinander entfernten Punkten gegen die auf der Schertrommel aufgewickelte Kette anliegende Tastorgane durch den beim Aufwickeln der Kette sich etwa ergebenden Höhenunterschied: selbsttätig und derart verstellt werden, daß unter Vermittlung von Hebelmechaüismen die. Bewegung der Tastorgahe auf einen Zeiger übertragen wird und dieser durch Ausschlagen aus seiner Mittelstellung den genannten Höhenunterschied sichtbar erkennen läßt. Die Tastorgane können aus Rollen, Tastern, Preß-' fingern o. dgl. gebildet sein.The new and peculiarity of the display device according to the invention consists in that two at spatially distant points against the one on the shear drum wound chain touching organs by the when winding the chain any resulting height difference: automatically and adjusted in such a way that under Mediation of lever mechanisms. Movement of the Tastorgahe on a pointer is transmitted and this by knocking out of its middle position the named Height difference can be seen visibly. the Touch organs can be formed from rollers, buttons, press fingers or the like.

Die Anzeigevorrichtung von der vorstehend gekennzeichneten Anordnung ist in der Zeichnung beispielsweise dargestellt.The display device of the arrangement indicated above is in the drawing for example shown.

Die auf einer Grundplatte α montierte Anzeigevorrichtung ist am Gestell der Schermaschine derart befestigt, daß die auf der obersten Kettschicht aufliegenden Tastorgane auf den höchsten Punkt der Schertrommel b auflaufen. Genannte Organe sind vorzugsweise aus den beiden Rollen C₁ c gebildet, vonThe display device mounted on a base plate α is attached to the frame of the shearing machine in such a way that the tactile elements resting on the uppermost warp layer run up to the highest point of the shearing drum b. Said organs are preferably formed from the two roles C ₁ c , of

Claims

each of which is mounted at the lower end of a measuring spindle d. The measuring spindles are guided in the bearings e, are secured against rotation in the same and are provided with incisions at their 5 upper ends in which the one-armed levers g, rotatable about the stationary pins f, rest. As can be seen from Fig. 2, the levers g are bent out in such a way that they can pass one another with their free ends. These free lever ends are connected to the upper end of a pointer i by pivot rods h attached to them, which is guided by a pin k attached to the base plate α when it swings out of its central position. Instead of the rollers c resting on the top warp layer, differently shaped organs, e.g. B. find those on the type of presser foot or fabric backer in sewing machines use. The mode of operation of the display device described is as follows: If the chain or the first band of the chain on the shearing drum b is correct, i. H. Sheared in the parallelogram cross-section, both rollers c are raised evenly, consequently the levers g resting on the upper ends of the measuring spindles d also make the same deflections und1 adjust the pointer in the vertical direction without the lower end of the pointer i moving from its central position . The pointer does not move to either side. If, on the other hand, the shearing of the chain does not take place parallel to the shearing drum b, but rather higher to the right as a result of excessive movement of the shaving comb (as indicated by dash-dotted lines in Fig. 1), the measuring spindle d on the right is raised higher than the spindle on the left. As a result, the right-hand lever g will deflect more than the left-hand lever; The upper end of the pointer i is knocked out to the right by the articulated rod h located on the left. Pin k deflects with its lower end to the left. But as soon as the pointer executes a visible deflection to the right or left, the worker operating the shearing machine recognizes that the shearing of the chain is no longer parallel to the shearing drum b; he can therefore immediately initiate proper shearing by changing the lateral movement of the shaving comb. In order to make yourself completely independent of the attention of the worker operating the machine, current connection bars can be attached to both soaps of the pointer i, which, when the pointer deflects of a certain size, close a circuit to make an electric bell sound. The regulation of the displacement of the shear comb by determining a mechanism that is activated when the electrical circuit is formed, i.e. to allow it to take place automatically, is also not excluded. By suitable choice of the lengths of the levers inserted between the measuring spindles and the pointer, a transmission ratio of about 1:10 can be achieved, so that, for example, with a height difference of 0.5 mm on the rollers c, the pointer i causes a deflection of 5 mm ..
