Description
Die Erfindung betrifft eine Vorrichtung zum Eindosieren von insbesondere pulverförmigen Füllgutes gemäß Oberbegriff des Patentanspruches 1.The invention relates to a device for metering in, in particular, powdery filling goods.
Eine Vorrichtung der gattungsgemäßen Art ist bspw. nach der DE-A- 35 43 507 bekannt. Diese bekannte Vorrichtung arbeitet zwar einwandfrei, hat aber insofern den Nachteil, daß in der Trommel nur zwei sich gegenüberstehende Zylinderreihen angeordnet werden können, die Hubverstellung im Inneren der Trommel erfolgen muß und daß die Trommel, da sie wegen der Stelltraversen keine tragende Welle aufweist, einer Trommelumfangslagerung bedarf. Der Leistung einer solchen Dosiervorrichtung sind insofern Grenzen gesetzt, als hierbei immer nur oben gefüllt und unten entleert werden kann, und es einer halben Umdrehung der Trommel bedarf, um leere Zylinder wieder in Füllstellung und um gefüllte Zylinder in Entleerungsstellung zu bringen. Dosiervorrichtungen mit Zentralwelle sind nach den US-A-3 154 117 und 4 052 836 bekannt. Um die Kolben dieser Vorrichtungen in den sich drehenden Trommeln einerseits bewegen und andererseits auch bezüglich ihrer Dosierhübe einstellen zu können, sind mechanisch recht aufwendige Verstell- und Bewegungselemente erforderlich, weshalb bei beiden Vorrichtungen nur Zylinder/Kolbenanordnungen auf einer Umfangslinie der relativ schmalen Trommel vorgegeben sind. Wollte man mehrere Reihen von Zylinder/Kolbenanordnungen nebeneinander vorsehen, so wäre dies nur durch Nebeneinanderanordnung mehrerer solcher Vorrichtungen möglich, wobei noch darauf geachtet werden müßte, daß die Verstellelemente, sofern dies überhaupt möglich ist, für eine Verstellung zugänglich bleiben. Eine solche relativ dichte Nebeneinanderanordnung ist aber durchaus von Interesse, wenn Behälter oder Näpfchen in Reihe nebeneinander angeordnet gefüllt werden sollen, wie dies bei der Vorrichtung nach der DE-A- 35 43 507 vorgesehen ist.A device of the generic type is known, for example, from DE-A-35 43 507. This known device works perfectly, but has the disadvantage that only two opposing rows of cylinders can be arranged in the drum, the stroke adjustment must take place inside the drum and that the drum, because it has no supporting shaft because of the adjusting crossbars, one Circumferential drum storage required. The performance of such a metering device is limited insofar as it can only be filled at the top and emptied at the bottom, and it takes half a revolution of the drum to bring empty cylinders back into the filling position and around filled cylinders into the emptying position. Central shaft metering devices are known from US-A-3 154 117 and 4 052 836. In order to be able to move the pistons of these devices in the rotating drums on the one hand and to adjust their metering strokes on the other hand, mechanically quite complex adjustment and movement elements are required, which is why in both devices only cylinder / piston arrangements are specified on a circumferential line of the relatively narrow drum. If one wanted to provide several rows of cylinder / piston arrangements next to one another, this would only be possible by arranging several such devices next to one another, care still being taken to ensure that the adjustment elements, if this is possible at all, remain accessible for adjustment. Such a relatively dense side-by-side arrangement is of interest, however, if containers or cups are to be filled in a row next to one another, as is provided in the device according to DE-A-35 43 507.
Ausgehend von der gattungsgemäßen Vorrichtung nach der DE-A-35 53 507 liegt der Erfindung die Aufgabe zugrunde, diese trotz der Verwendung von Kolbenbetätigungstraversen, dahingehend zu verbessern, daß mehr als zwei Reihen sich diametral gegenüberstehender Zylinder an der Trommel vorgesehen werden können, wobei zudem der Saug- bzw. Dosierhub unabhängig vom Ausstoßhub einstellbar sein soll.Starting from the generic device according to DE-A-35 53 507, the invention is based on the object, in spite of the use of piston actuating traverses improve that more than two rows of diametrically opposed cylinders can be provided on the drum, the suction or metering stroke should also be adjustable independently of the exhaust stroke.
Diese Aufgabe ist mit einer Vorrichtung der gattungsgemäßen Art nach der Erfindung dadurch gelöst, daß die Trommel beidendig mittels einer geraden und der Anzahl der Zylinderreihen entsprechenden Anzahl von mindestens vier radialen Speichen auf einer zentrisch die Trommel durchgreifenden Welle gelagert und an den Speichen eines Speichenpaares jeweils eine Kolbenbetätigungstraverse verschieblich geführt ist und daß im Stellweg der Traversenrollen quer zur Welle ein den vollen Ausstoßhub bewirkender Stellhebel und ein weiterer, den Saughub bewirkender Stellhebel angeordnet sind, wobei die Hebelverstellungen bewirkende drehbare Stellkurven zur Synchrondrehung miteinander gekoppelt sind und die den Saughub bewirkende Stellkurve in bezug auf den betreffenden Stellhebel verstellbar angeordnet ist.This object is achieved with a device of the generic type according to the invention in that the drum is supported on both ends by means of a straight number of at least four radial spokes corresponding to the number of rows of cylinders on a shaft which passes centrally through the drum and one each on the spokes of a pair of spokes Piston actuating crossmember is displaceably guided and that in the travel of the crossbeam rollers transverse to the shaft a control lever effecting the full ejection stroke and a further control lever causing the suction stroke are arranged, the lever adjustments causing rotating control curves for synchronous rotation being coupled to one another and the control curve causing the suction stroke with respect to the relevant control lever is arranged adjustable.
Abgesehen davon, daß bei dieser erfindungsgemäßen Ausbildung die Trommel von einer normal zu lagernden Zentralwelle getragen wird und mindestens vier Reihen von Zylindern vorgesehen werden können und damit die Durchsatzleistung entsprechend erhöht werden kann, ergibt sich durch die im einzelnen noch näher zu erläuternde Einstell- und Betätigungsmechanik, daß auf einfache Weise und völlig unabhängig vom Entleerungshub der Saug- bzw. Dosierhub eingestellt werden kann. Wesentlicher Grundgedanke ist dabei, das Stellelement, das den Entleerungshub bewirkt, immer den vollen Hubausschlag ausführen zu lassen, und zwar unabhängig davon, auf welche Dosierhubeinstellung die Kolben vorher eingestellt worden sind, was noch näher erläutert wird.Apart from the fact that in this configuration according to the invention the drum is carried by a central shaft to be supported normally and at least four rows of cylinders can be provided and thus the throughput can be increased accordingly, results from the adjusting and actuating mechanism to be explained in more detail below that the suction or metering stroke can be set in a simple manner and completely independently of the emptying stroke. The main basic idea here is to have the actuating element which effects the emptying stroke always carry out the full stroke deflection, regardless of the metering stroke setting to which the pistons have previously been set, which will be explained in more detail below.
Um die Stellmechanik nur auf einer Seite anordnen zu müssen, dabei aber eine gleichmäßige und verkantungsfreie Hub- und Senkbewegung der Kolbenbetätigungstraversen über deren ganze Länge zu gewährleisten, sind die mindestens vier Kolbenbetätigungstraversen mit Kugelführungshülsen an den Speichen geführt.In order to only have to position the actuating mechanism on one side, but to ensure a smooth and tilt-free lifting and lowering movement of the piston actuating crossbeams over their entire length, the at least four piston actuating crossbeams are guided on the spokes with ball guide sleeves.
Trotz der vom Entleerungshub unabhängigen Einstellbarkeit des Saughubes können die notwendigen Stellkurven vorteilhaft für beide Vorgänge in gleicher Form und Größe und Exzentrizität ausgebildet sein, da die Saughubeinstellung nicht durch eine abweichende Kurvenkonfiguration erreicht wird, sondern diese Saughubeinstellung lediglich durch eine Distanzverstellung der Saughubkurve zur jeweiligen in Wirkstellung befindlichen Kolbenbetätigungstraverse erfolgt. Im übrigen können diese Stellkurven als einfache exzentrische Kreisscheiben ausgebildet werden. Diese Distanzverstellung könnte an sich dadurch verwirklicht werden, daß die Drehachse der Stellkurve für den Saughub in geeigneter Weise verstellbar am Vorrichtungsgestell gelagert wird. Vorteilhaft ist jedoch seine Ausbildung derart vorgesehen, daß dem den Saughub bewirkenden Stellhebel ein zweiter, am entgegengesetzten Ende schwenkbar gelagerter Stellhebel mit entgegengesetzter Erstreckungsrichtung übergeordnet ist, dessen über dem Schwenklager des Stellhebels befindliches Ende in bezug auf das Schwenklager des anderen Stellhebels distanzverstellbar ausgebildet und am übergeordneten Stellhebel die auf das Ende des darunter befindlichen Stellhebels wirkende Stellkurve angeordnet ist.Despite the fact that the suction stroke can be adjusted independently of the emptying stroke, the necessary positioning curves can advantageously be designed for both processes in the same shape and size and eccentricity, since the suction stroke setting is not achieved by a different curve configuration, but this suction stroke setting is only achieved by adjusting the distance of the suction stroke curve to the respective active position located piston actuation crossbar. Otherwise, these control curves can be designed as simple eccentric circular disks. This distance adjustment could be realized per se by the fact that the axis of rotation of the positioning curve for the suction stroke is mounted in an appropriately adjustable manner on the device frame. However, its design is advantageously provided in such a way that the control lever causing the suction stroke is superimposed on a second control lever pivotally mounted at the opposite end with the opposite direction of extension, whose end located above the pivot bearing of the control lever is designed to be distance-adjustable with respect to the pivot bearing of the other control lever and on the parent Actuating lever is arranged on the actuating curve acting on the end of the actuating lever located below.
Dies führt zu einer noch näher zu erläuternden linearen Verstellbarkeit. Der zweite, übergeordnete Stellhebel kann auf der gleichen Achse wie die den Entleerungshub bewirkende Stellkurve gelagert sein und es muß keine Rücksicht auf die erforderliche Synchronkopplung der beiden Stellkurven genommen werden, der sonst durch eine entsprechend gekurvte Schlitzführung am Vorrichtungsgestell für die Lagerung und Führung der den Saughub bewirkenden Stellkurve Rechnung getragen werden müßte.This leads to a linear adjustability to be explained in more detail. The second, higher-level control lever can be mounted on the same axis as the control curve causing the emptying stroke and there is no need to take into account the required synchronous coupling of the two control curves, which would otherwise be achieved by a correspondingly curved slot guide on the device frame for the storage and guidance of the suction stroke effecting curve should be taken into account.
Was die Betätigung der Kolben für den Ausstoßhub betrifft, so ist dafür der den Ausstoßhub bewirkende Stellhebel ein zweiarmiger, im wesentlichen mittig schwenkbar gelagerter Winkelhebel, dessen einer Arm mit seinem Ende an der Stellkurve anliegt und dessen anderer Arm am Ende mit einem von den Traversenrollen unterfahrbaren Querfortsatz versehen ist.As far as the actuation of the pistons for the ejection stroke is concerned, the actuating lever causing the ejection stroke is a two-armed, essentially pivotable angular lever, one end of which rests against the cam and the other arm at the end of which is traversable by one of the truss rollers Transverse process is provided.
Die an einer Seite aller Traversen angeordneten Rollen laufen bei Schrittdrehung der Trommel von unten gegen den den Saughub bewirkenden Stellhebel und der am anderen, den Ausstoßhub bewirkenden Stellhebel angeordnete Querfortsatz wird von den von oben in Schrittdrehung kommenden Rollen unterfahren.The rollers arranged on one side of all traverses run from below against the actuating lever causing the suction stroke when the drum is rotated, and the transverse extension arranged on the other actuating lever causing the ejection stroke is driven under by the rollers coming from above in incremental rotation.

Die Vorrichtung besteht aus einer unter einer Produktaufgabeeinrichtung 1 drehbar angeordneten Trommel 2 mit nach außen offenen Produktaufnahmegefachen in Form sich radial gegenüberstehender Zylinder 3 mit bezüglich ihres Hubes einstellbaren Kolben 4 und Kolbenstangen 5, wobei die Kolben 4 einer Zylinderreihe 3' mit ihren Kolbenstangen 5 jeweils an einer sich im Inneren der Trommel 2 erstreckenden Kolbenbetätigungstraverse 6 befestigt sind, die außerhalb der Trommel 2 über Rollen 7 mit Hubbewegungselementen in Wirkverbindung bringbar sind. Die Trommel 2 ist natürlich mindestens auf der Seite, auf der sich die gefüllten Zylinder 3 nach unten bewegen, mit einger geeigneten Abdeckung A versehen.The device consists of a
Für eine solche Vorrichtung ist nun wesentlich, daß die Trommel 2 beidendig mittels einer geraden und der Anzahl der Zylinderreihen 3' entsprechenden Anzahl von mindestens vier radialen Speichen 8 auf einer zentrisch die Trommel 2 durchgreifenden Welle 9 gelagert und an den Speichen 8 eines Speichenpaares 8' jeweils eine Kolbenbetätigungstraverse 6 verschieblich geführt ist. Ferner sind dabei im Stellweg der Traversenrollen 7 quer zur Welle 9 ein den vollen Ausstoßhub bewirkender Stellhebel 10 und ein weiterer, den Saughub bewirkender Stellhebel 11 angeordnet, wobei die Hebelverstellungen bewirkende drehbare Stellkurven 12, 12' zur Synchrondrehung miteinander gekoppelt und die den Saughub bewirkende Stellkurve 12' in bezug auf den Stellhebel 11 verstellbar angeordnet ist.For such a device it is now essential that the
Bei dem dargestellten Ausführungsbeispiel sind insgesamt (siehe Fig. 1, 2) vierundzwanzig Zylinder 3 mit Kolben 4 und Kolbenstangen 5 vorhanden, wobei jeweils vier Zylinder in Reihe (siehe Fig. 2) angeordnet sind und jeder Reihe ein Speichenpaar 8' mit zugehöriger Betätigungstraverse 6 zugeordnet ist. Jede Traverse 6 ist an ihren Enden mittels Kugelführungshülsen 13 an den zugehörigen Speichen 8 geführt, wobei alle Speichen 8 die Welle 9 in der Längsmittelachse der Trommel 2 halten.In the illustrated embodiment, there are a total of (see FIGS. 1, 2) twenty-four
Unter Verweis auf Fig. 4 sind die Stellkurven 12, 12' bspw. in Form von exzentrisch gelagerten Kreisscheiben 14 ausgebildet. Ebenfalls unter Verweis auf Fig. 4 ist der den Ausstoßhub bewirkende Stellhebel 10 ein zweiarmiger, im wesentlichen mittig schwenkbar gelagerten Winkelhebel, dessen einer Arm 10' mit seinem Ende an der Stellkurve 12 anliegt und dessen anderer Arm 10'' am Ende mit einem von den Traversenrollen 7 unterfahrbaren Querfortsatz 15 versehen ist (siehe auch Fig. 3).With reference to FIG. 4, the
Bei der bevorzugten Ausführungsform der Verstellmechanik gemäß Fig. 4 ist dem den Saughub bewirkenden Stellhebel 11 ein zweiter, am entgegengesetzten Ende schwenkbar gelagerten Stellhebel 11' mit entgegengesetzter Erstreckungsrichtung übergeordnet, dessen über dem Schwenklager 16 des Stellhebels 11 befindliches Ende 17 in bezug auf das Schwenklager 16 distanzverstellbar ausgebildet ist. Dabei ist am Stellhebel 11' die auf das Ende des darunter befindlichen Stellhebels 11 wirkende Stellkurve 12' angeordnet.In the preferred embodiment of the adjustment mechanism according to FIG. 4, a
Die bspw. als exzentrisch gelagerte Kreisscheiben 14 ausgebildeten Stellkurven 12, 12' stehen bspw. mit einem Kettentrieb 14' in Verbindung, drehen also im Schrittakt synchron, wobei diese Scheiben 14 bzgl. ihrer Exzentrizität und bei Anordnung der Stellhebel wie dargestellt um 90° versetzt angeordnet sind. Außerdem ist der übergeordnete Stellhebel 11' mit seinem Schwenklagerende 18 auf der gleichen Achse 19 wie die drehbare Stellkurve 12 für den Stellhebel 10 gelagert, d.h., bei Distanzverstellung der beiden Stellhebel 11, 11' mittels einer Stellspindel 20 wird der Stellhebel 11' in Pfeilrichtung P um die Achse 19 verschwenkt und damit auch die Stellkurve 12 angehoben.The
Der Stellhebel 11 steht dabei immer in Höchststellung, d.h., der Stellung, bei der die Kolben 4 einer Reihe 3' bei Erreichen der Füllstellung unter der Produktaufgabeeinrichtung 1 die Zylinder 3 nach oben abschließen. Jenachdem wie nun der Stellhebel 11' eingestellt ist, ergibt sich bei Drehung der Stellkurve 12' ein mehr oder weniger tiefer Saughub der Kolben 4. Da sich dabei auch die andere Stellkurve 12 mitdreht, erfolgt in der darunter befindlichen Zylinderreihe via Winkelhebel 10, Querfortsatz 15, Rolle 7 und zugehöriger Traverse 6 der Entleerungshub. Die Kolben 4 sind dabei in ihren Zylindern 3 straff geführt, so daß diese ihre vom Stellhebel 11 vorgegebene Dosiereinstellung beibehalten. Da der Winkelhebel 10 mit dem Querfortsatz 15 immer die volle Hubhöhe ausführt, ist es für den Entleerungshub unwesentlich, in welcher Höhe die unterfahrene Rolle 7 steht, da diese immer vom Querfortsatz bis zur Endstellung mitgenommen wird. Der Stellhebel 11 und der Arm 10' des Stellhebels werden mit Federn F an den Stellkurven 12, 12' in Kontakt gehalten, wobei die Federn F am nicht näher dargestellten Vorrichtungsgestell verspannt sind.The
