Description

Die Erfindung betrifft zwanggeführte Schwing förderrinnen, die mittels mehrerer verschieden großer und mit unterschiedlicher Frequenz umlaufender Unwuchten erregt werden. The invention relates to positively driven vibrating conveyor troughs by means of several unbalances of different sizes and rotating at different frequencies get excited.

Eine durch Unwuchten in Schwingung versetzte Rinne größerer Länge fördert dadurch, daß sie auf schräg gestellten Lenkerfedern oder auf Schxvinghebeln gelagert ist. Diese Zwangführung verhindert jedes Flattern der erregten Rinne. Aus der horizontalen Erregungskraft wird durch die Zwangführung eine schräg aufwärts gerichtete Komponente abgeleitet, die eine wurfartige Förderbewegung des Rinnengutes zur Folge hat. Gleichzeitig entsteht dabei aber auch eine schräg abwärts gerichtete Kraftkomponente, die eine entsprechend schwere Ausbildung des Fundamentes erfordert. Das Ausmaß der vom Fundament aufzunehmenden Kräfte kann mehrere tausend Kilogramm betragen. A channel of greater length set in vibration by imbalances promotes by the fact that they are on inclined trailing arms or on Schxvinghebeln is stored. This forced guidance prevents any fluttering of the excited channel. the end the horizontal excitation force is inclined upwards due to the forced guidance Directed component derived, which a litter-like conveying movement of the channel material has the consequence. At the same time, however, there is also a downward slope Force component that requires a correspondingly heavy construction of the foundation. The extent of the forces to be absorbed by the foundation can be several thousand kilograms be.

Der Erfindung liegt die Aufgabe zugrunde die vom Fundament aufzunehmende Kraftkomponente bei zwanggeführten Schwingförderrinnen mit Unwuchterregern dadurch zu vermeiden, daß auf die vertikale Bewegungskomponente verzichtet wird. The invention is based on the object to be taken up by the foundation Force component in forcibly guided vibratory feeders with unbalance exciters as a result to avoid that the vertical movement component is foregone.

Kennzeichnend für die Schwingförderrinne nach der Erfindung ist demnach, ,daß die Wirkungsl-inie ihres Schwingungserregers mit der Längsrichtung der Förderrinne zusammenfällt und daß dessen NeJbenerregungsunwuchten mit der doppelten Drehzahl umlaufen, wie die mit ihnen formschlüssig gekuppelten Grunderregungsunwuchten und ein Viertel von deren statischem Massenmoment aufweisen.Characteristic for the vibratory conveyor trough according to the invention is therefore, that the active line of your vibration exciter with the longitudinal direction of the conveyor trough coincides and that its secondary excitation imbalances with double the speed circulate, such as the basic excitation unbalances and have a quarter of their static moment of inertia.

Mit dem erfindungsgemäßen Erreger werden also eine Grundschwingung sowie höherharmonische Schwingungen erzeugt und miteinander überlagert, wodurch sich nichtharmonische, jedoch gleichförmige, periodische Schwingungen ergeben.With the exciter according to the invention, a fundamental oscillation is thus established as well as higher harmonic vibrations generated and superimposed on each other, whereby non-harmonic, but uniform, periodic oscillations result.

Da die Erregung und der Schwingweg ausschließlich horizontal verlaufen, kann man an Stelle senkrechter Lenkerfedern für die Abstützung der Förderrinne vorteilhafterweise Schraubenfedern. Since the excitation and the oscillation path are exclusively horizontal, can be used in place of vertical trailing arms to support the conveyor trough advantageously Coil springs.

Rollen od.,dgl., selbst eine einfache Gleitlagerung verwenden. Zu beachten ist lediglich, daß die gewählte Art der Lagerung einer horizontalen Bewiegung keine wesentlichen Kräfte entgegensetzt.Rollers or the like, even use a simple plain bearing. to The only thing to note is that the type of storage chosen is a horizontal movement does not oppose any essential forces.

An Hand der Zeichnung wird der Erfindungsgegenstand näher erläutert. The subject matter of the invention is explained in more detail using the drawing.

In Abb. I i;st eine auf Lenkerfedern F zwanggeführte Förderrinne R schematisch veranschaulicht. Der Erreger besteht aus den gegensinnig umlaufenden Unwuchtmassen G (Grunderreger), die mit dem größten statischen Massenmoment und der Drehzahl » (Grundfrequenz) die Grunderregung erzeugen, sowie aus den gegensinnig umlaufenden Unwuchtmassen N (Nebenerreger), die mit der Drehzahl 2n und je ein Viertel des statischen Massenmomentes einer Grundunwuchtmasse G ausgerüstet, durch Überlagerung mit der Grunderregung die nichtharmonische Schwingung hervorrufen. In Fig. I i; is a conveyor trough forcibly guided on trailing arm springs F. R illustrated schematically. The pathogen consists of those rotating in opposite directions Imbalance masses G (basic exciter), those with the largest static mass moment and the speed »(basic frequency) generate the basic excitation, as well as from the opposite directions revolving unbalanced masses N (secondary exciters), each with a speed of 2n and a quarter of the static mass moment of a basic unbalanced mass G equipped by superposition cause the non-harmonic oscillation with the basic excitation.

Praktische Versuche haben ergeben, daß es im allgemeinen genügt, die Schwingungen von einem Grund- und nur einem Nebenerreger zu überlagern um einen hinreichenden Fördereffekt von beispielsweise 5 m und mehr in der Minute zu erzielen. Je nach der Drehrichtung des Antriebsmotors für die Erreger kann die Förderrichtu-ng sowohl nach links als auch nach rechts gewählt werden. Practical tests have shown that it is generally sufficient to superimpose the vibrations of one basic and only one secondary exciter by one To achieve a sufficient conveying effect of, for example, 5 m and more per minute. Depending on the direction of rotation of the drive motor for the exciters, the conveying direction can can be chosen to the left as well as to the right.

Aus Abb. 2, welche die Geschwindiglçeitsverhältnisse einer erfind,ungsgemäßen Förderrinne wiedergibt, erhellt, daß im Verlauf einer Schwingungsperiode die Geschwindigkeit (-v) der Förderrinne gemäß Abb. 1 nach rechts, {dargestellt durch die negative Ordinate, länger wirksam ist, als die Geschvindigkeit (+v) nach links, die durch die positive Ordinate des Diagramms dargestellt ist. From Fig. 2, which shows the speed ratios of an invented, appropriate Conveyor channel reproduces, it is clear that in the course of a period of oscillation the speed (-v) of the conveyor trough according to Fig. 1 to the right, {represented by the negative ordinate, is effective longer than the speed (+ v) to the left caused by the positive Ordinate of the diagram is shown.

Die Fördergeschwindigkeit stellt sich so ein, daß die Relativgeschwindigkeit des Fördergutes in bezug auf die Förderrinne gleich lang nach rechts und links gerichtet ist. In diesem Fall sind dlann Verzögerung und Beschleunigung infolge der Reibung gleich lang wirksam, so daß die Geschwindigkeit zu Ende der Periode genau so groß ist wie zu Beginn der Periode. Das Fördergut wird demnach nach rechts bewegt. The conveying speed adjusts itself so that the relative speed of the material to be conveyed is directed to the right and left with the same length in relation to the conveyor trough is. In this case, the deceleration and acceleration are due to friction effective for the same time, so that the speed at the end of the period is just as great is like the beginning of the period. The conveyed material is accordingly moved to the right.
