Description
Vorrichtung zum messen der Dicke von Papier- bzw. Pappebähnen mit einer auf der Bahn ruhenden, auf einen Zeiger wirkenden Fühlrolle Die Erfindung betrifft eine Vorrichtung zur Feststellung der Dicke von Papier- oder Pappebahnen mittels einer auf der Bahnaufliegenden FühlTolle, die einen Zeiger einstellt. Man hat bei: derartigen Vorrichtungen bisher die Anzeigevorrichtung in einem Träger angeordnet, der am Maschinen gestell festgieschraubt ist. Diese Anordnung ist mangelhaft; denn bei Benutzung angeschraubter Träger zittert der Zeiger fast ständig, da die Erschütterungen der Maschine auf ihn übertragen werden. Ein genaues Ablesien ist dabei kaum möglich.Device for measuring the thickness of paper or cardboard sheets a feeler roller resting on the track and acting on a pointer. The invention relates to a device for determining the thickness of paper or cardboard webs by means of a FühlTolle lying on the track, which adjusts a pointer. Man has so far in such devices the display device in a carrier arranged, which is firmly screwed to the machine frame. This arrangement is flawed; because when using screwed-on brackets, the pointer trembles almost constantly because the Machine vibrations are transmitted to him. An accurate reading is hardly possible.
Nach der Erfindung soll eine ruhige und richtige Zeigereinste11ung dadurch herbeigeführt werden., daß die Anzeigevorrichtung in einem auf - den freien Enden der Walz ruhenden Träger angeordnet wird. Die Anzeigevorrichtung und der Schaft der Fühlrolle sind beispielsweise in einem. senkrecht verschiebbaren. Träger angebracht, der sich mit Laufrollen auf die freien. Enden der Walze stützt. Um dabei zu verhindern, daß die Fühlrolle auch bei der Herstellung dicker Pappein. ständig umläuft, wird zweckmäßig der Schaft der Rolle mit einem Bund auf einer Platte des Trägers abgestützt. Man, kann. dabei die Anordnung so treffen, daß die tiefste Lage dex Fühlrolle veränderlich ist.According to the invention, a smooth and correct pointer setting be brought about. That the display device in an on - the free Ends of the roller resting beam is arranged. The indicator and the stem the feeler roller are, for example, in one. vertically movable. Carrier attached, the one with castors on the free. Ends of the roller supports. In order to prevent that the feeler role is also used in the production of thick cardboard. is constantly going around the shaft of the roller is expediently supported with a collar on a plate of the carrier. One can. make the arrangement in such a way that the lowest position dex feeler roller can be changed is.
In der Zeichnung ist eine Ausführung der Vorrichtung dargestellt. Es zeigen: Abb. i .eine Vorderansicht und teiilweisen Schnitt, Abb. 2 eine Seitenansicht und teilweisen S chnitt, und Abb.3 einen wagerechten Schnitt nach S'chnitdinüe A-B durch die Führung @des@ Trägers.In the drawing, an embodiment of the device is shown. They show: Fig. 1 a front view and partial section, Fig. 2 a side view and partial section, and Fig. 3 a horizontal section according to S'chnitdinüe A-B through the leadership @ of the @ carrier.
Der Träger b, welcher die Anzeigevurrichtunga des Dickenmessers ienthMt, ruht mief zwei Laufrollen d unmittelbar auf der Pappenwalzee. Diese trägt in. ihrem mittleren Teil die Pappebahn f, und auf dieser läuft in bekannter Weise die Fühlrolle c, welche auf die Anzeigevorrichtung a einwirkt. Der Träger besitzt außerdem seitliche Führungsstücke, die in den senkrechten Führungen ä gleiten. Wenn sich die Walze e hebt oder senkt, so heben oder senken sich in gleicher Weise sowohl die Laufrollen d als auch die Fühlwalze c. Das Heben und Senken der Walze übt somit keinen Einfluß auf die An.zeigevorrichtunga aus. Ändert sich dagegen. die Stärke der Papp,ebahu f, so wird die Fühlwalze c gegenüber den Laufrollend angehoben und damit der Zeiger verstellt. Die Unterschiede in der Stärke der Pappebahn werden somit unbeeinflußt von Erschütterungen der Maschine von dem Zeiger angegeben.The carrier b, which ienthMt the display device a of the thickness meter, two rollers d rests directly on the cardboard roller. This carries in middle part the cardboard web f, and on this the feeler roller runs in a known manner c, which acts on the display device a. The carrier also has lateral Guide pieces that slide in the vertical guides ä. When the roller e raises or lowers, so both raise and lower the rollers in the same way d as well as the feeler roller c. The raising and lowering of the roller therefore has no effect on the display device a. Changes against it. the strength of the cardboard, ebahu f, the feeler roller c is raised with respect to the roller end and thus the pointer adjusted. The differences in the thickness of the cardboard web are thus unaffected of vibrations of the machine indicated by the pointer.
Die Übertragung der Bewegung der Fühlrolle auf den Zeiger erfolgt in beliebiger bekannter Weise, beispielsweise dadurch, daß eine an dem Schaft h angebrachte Zahnstange-nicht gezeichnet-in ein auf der Zeigerwelle sitzendes Ritzel eingreift. Damit bei .der Herstellung dicker Pappe die Fühlrolle c- nicht von. Anfang an über die Pappe zu laufen braucht, wird die Bewegung der Rolle nach unten hin. begrenzt. Der Schaft h stützt sich mittels eines Bundes i auf eine Brücke k, die in verschiedenen Höhenlagen festschraubbar ist. Die Anzeigevorrichtung tritt erst in Wirkung, wenn die Pappe so-,dick wird, daß sie unter die Rolle c drückt und dabei den Bund! von der Brücke abhebt.The movement of the feeler roller is transferred to the pointer in any known manner, for example in that a on the shaft h attached rack - not shown - in a pinion seated on the pointer shaft intervenes. So that when thick cardboard is produced, the feeler roller c- does not come from. Beginning needs to run across the cardboard, the movement of the roll is downwards. limited. The shaft h is supported by means of a collar i on a bridge k which can be screwed on at different heights. The display device only appears in effect when the cardboard is so thick that it presses under the roller c and thereby the covenant! lifts off the bridge.
