Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um beim Antriebe von Schüttelsieben, Sortirmaschinen u. dgl. durch Pleuelstangen die Stöfse zu vermindern, bringt man an den Pleuelstangen federnde Zwischenglieder an. Diese bestehen aus einem Rahmen mit gegen einander gespannten Federn, die entsprechend der in der Pleuelstange wechselnden Kraftrichtung abwechselnd zur Wirkung kommen. Bisher wurde dieses federnde Glied zwischen den beiden Enden der Pleuelstange eingeschaltet (vergl. die Patentschrift 30279), so dafs der Schwerpunkt des schweren Federrahmens innerhalb der Pleuelstangenenden lag. Der Schwerpunkt macht daher nicht blos die hin- und hergehenden Bewegungen des gerade geführten Pleuelstangenendes, sondern auch in einem der Entfernung von diesem Ende der Pleuelstange entsprechenden Mafse die durch den Kurbelantrieb bedingten Schwingungen senkrecht zur Bewegungsrichtung dieses Pleuelstangenendes mit. Dadurch entstanden bei der Umkehr dieser Schwingbewegung unter der Einwirkung der Masse des Federrahmens Stöfse senkrecht zur Bewegungsrichtung des gerade geführten Pleuelstangenendes, die auf den Sieb-, Sortiro. dgl. Procefs schädlichen Einflufs hatten. Diese Stöfse sollen nach der vorliegenden Erfindung dadurch vermindert werden, dafs der Schwerpunkt des Federrahmens in den gerade geführten Endpunkt der Pleuelstange oder in dessen Nähe verlegt wird.In order to drive vibrating sieves, sorting machines and the like by connecting rods To reduce jolts, resilient links are attached to the connecting rods. These consist of a frame with springs that are tensioned against each other the alternating direction of force in the connecting rod come into effect. So far, this resilient member was switched on between the two ends of the connecting rod (See the patent specification 30279), so that the center of gravity of the heavy spring frame within the connecting rod ends. The center of gravity therefore does not just make the to and fro Movements of the straight end of the connecting rod, but also at a distance from this end of the connecting rod corresponding measure the vibrations caused by the crank drive perpendicular to the Direction of movement of this connecting rod end with. This resulted in repentance this oscillating movement under the action of the mass of the spring frame Stöfse perpendicular to the direction of movement of the straight end of the connecting rod, which is directed to the sieve, Sortiro. Like. Procefs had harmful influence. These plugs are intended according to the present invention be reduced by the fact that the center of gravity of the spring frame in the straight end point of the connecting rod or in the vicinity of which is relocated.

Die Federn sind in der Form von Schraubenfedern Z2 an Führungsstangen Z1 in einem Rahmen r untergebracht. Zwischen den Federn /2 sitzt auf den Führungsbolzen Z1 ein Querhaupt t, an welches die in dem Rahmen r verschiebbar gelagerte Pleuelstange D1 angeschlossen ist. Der Rahmen selbst ist mittels seiner seitlichen Zapfen r1 (Fig. 2) drehbar in Augen E gelagert, welche unterhalb des Gestelles des Siebes o. dgl. befestigt sind. Das letztere wird durch die Kreissectorschwingen F in bekannter Weise wagerecht geführt.The springs are housed in the form of helical springs Z 2 on guide rods Z 1 in a frame r. Between the springs / 2 sits on the guide pin Z 1 a crosshead t, to which the connecting rod D 1, which is slidably mounted in the frame r, is connected. The frame itself is rotatably mounted in eyes E by means of its lateral pins r 1 (FIG. 2), which are fastened below the frame of the sieve or the like. The latter is guided horizontally by the circular sector swing arms F in a known manner.

Durch die Hin- und Herbewegung der Pleuelstange D : und des mit dieser verbundenen Querhauptes t werden die Federn Z2 abwechselnd ge- und entspannt und nehmen somit die Stöfse beim Vor- und Rückwärtsgange der Siebvorrichtung auf.Due to the back and forth movement of the connecting rod D : and the crosshead t connected to it, the springs Z 2 are alternately tensioned and relaxed and thus absorb the jolts when the screening device moves forwards and backwards.

Da der Federrahmen r hierbei um den Schwerpunkt schwingt, so giebt er zu Stöfsen senkrecht zur Base der Zapfen r1 keine Veranlassung. Die gröfsere Anzahl der Schraubenfedern Z2 gestattet, ihren Durchmesser und somit die Höhe des Rahmens r verhältnifsmäfsig klein zu machen, so dafs der Abstand der Zapfen r1 von der Unterfläche des Siebgestelles nur gering zu sein braucht.Since the spring frame r here swings around the center of gravity, it does not give rise to impacts perpendicular to the base of the pin r 1 . The larger number of helical springs Z 2 allows their diameter and thus the height of the frame r to be made relatively small, so that the distance between the pin r 1 and the lower surface of the sieve frame need only be small.
