Description

Die Erfindung betrifft eine Einspeisevorrichtung für Schneckenmaschinen mit einem in einem Aufgabebehälter antreibbar gelagerten Einspeiserad, durch welches das Gut einer ebenfalls im Aufgabebehälter gelagerten Schnecke zugeführt wird.The invention relates to a feed device for Screw machines with one in a feed container drivable mounted feed wheel, through which the Well one also stored in the feed container Snail is fed.

Schneckenmaschinen werden bevorzugt zum Fördern und Homogenisieren von pasteusen, körnigen oder feucht­ fasigeren und pulvrigen Gutes verwendet. Solange pasteuse Güter, die durch eigenes Fließen den Einzugsraum der Schneckenmaschine füllen, gefördert werden, ist es nicht erforderlich, in dem Aufgabebehälter spezielle Einspeisevorrichtungen anzubringen. Bei backendem Gut hingegen muß dies geschehen. Backende Güter neigen dazu, an den Wänden des Aufgabebehälters hängen zu bleiben und durch Brückenbildung den Materialfluß aufzuhalten. Dadurch entsteht ein ungleichmäßiger Materialfluß in der Schnecke, der sich bei der Weiterverarbeitung des geförderten und homogenisierten Gutes unangenehm auswirken kann. Diese Einspeisehemmungen werden auf verschiedene Weise bekämpft. So sind z. B. elektromagnetisch oder pneumatisch angetriebene Vibratoren bekannt, die die gesamte Einfüllöffnung in Schwingung versetzen. Vielfach angwandt werden auch Hilfsschnecken, die senkrecht zu den Schnecken der Schneckenmaschine angeordnet sind und das Gut von oben sanft in diese eindrücken. Diese Hilfsschnecken sind meist konisch ausgebildet und rotieren in dem Aufgabebehälter, der eine Beschickungsöffnung besitzt. Weiterhin werden bevorzugt wegen der einfachen Bauweise Einspeiseräder benutzt, bei denen die Bügel eng an der Wand des Aufgabebehälters herstreichen und welche bei jeder Umdrehung eine dosierte Menge in die Fördergänge der Schnecke einstreichen soll. Die Praxis hat nun gezeigt, daß immer wieder Unregelmäßigkeiten in der Beschickung der Schnecke auftreten. Es wurde beobachtet, daß dies insbesondere darauf zurückzuführen ist, daß die Zwischenräume der Schnecke unterschiedlich stark mit Material gefüllt werden.Screw machines are preferred for conveying and Homogenize pasteuses, granular or moist more fibrous and powdery good used. As long as pasteuse goods that flow through the Fill the feed area of the screw machine, conveyed it is not necessary in which Feed container special feed devices to attach. With baking goods, however, this must be done happen. Baking goods tend to stick to the walls of the Feed hopper get stuck and through Bridging to stop the flow of material. Thereby creates an uneven material flow in the Snail, which is in the processing of the promoted and homogenized good uncomfortable can impact. These feed restrictions are on fought in different ways. So z. B. electromagnetically or pneumatically driven Vibrators known that the entire filler opening in Move vibration. They are also often used Auxiliary screws, the perpendicular to the screws of the screw machine are arranged and the goods gently into them from above  push in. These auxiliary screws are mostly conical trained and rotate in the feed container, the has a loading opening. Continue to be preferred because of the simple construction feed-in wheels used, where the bracket close to the wall of the Make feed container and which one for each Turn a metered amount into the conveying channels To snail. Practice has now shown that there are always irregularities in the feed the snail occur. It has been observed that this is particularly due to the fact that the Interspaces of the snail with different degrees Material to be filled.

Der vorliegenden Erfindung liegt daher das Problem zugrunde, eine Einspeisevorrichtung für Schneckenmaschinen der eingangs näher bezeichneten Art derart auszubilden, daß die einem Einspeiserad zugeordnete Schnecke stets gleichmäßig mit Material beladen wird. Dies wird erfindungsgemäß dadurch erreicht, daß die Drehrichtung des Einspeiserades veränderbar ist. Auf diese Weise wird nämlich der Förderschnecke Gut von beiden Seiten her zugeführt, so daß die Fördergänge der Schnecke stets von beiden Seiten her gefüllt werden.The present invention therefore has the problem based on a feed device for Screw machines of the type specified in the introduction to train such that the one feed wheel assigned snail always evenly with material is loaded. This is according to the invention achieved that the direction of rotation of the feed wheel is changeable. In this way, namely Screw conveyor Well fed from both sides, see above that the conveying paths of the screw are always from both sides be filled here.

Weiter vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen näher definiert.Further advantageous embodiments of the invention are defined in more detail in the subclaims.

Im folgenden soll die Erfindung anhand eines Ausführungsbeispieles und mehrer dieses schematisch darstellender Figuren näher erläutert werden. Dabei zeigt:In the following the invention is based on a Embodiment and several of this schematically performing figures closer are explained. It shows:

Fig. 1 eine Einspeisevorrichtung für eine Schneckenmaschine in der Seitenansicht, Fig. 1 is a feed device for a screw machine in side view,

Fig. 2 die in Fig. 1 dargestellte Einspeisevorrichtung in der Seitenansicht sowie den Schnitt der Linie II-II in Fig. 1 und Fig. 2 shows the feed device shown in Fig. 1 in side view and the section of line II-II in Fig. 1 and

Fig. 3 die in Fig. 1 dargestellte Einspeisevorrichtung gemäß der Linie III-III in Fig. 1. Fig. 3, the feeding device shown in FIG. 1 according to the line III-III in Fig. 1.

Mit 1 ist ein trogförmiger Aufgabebehälter bezeichnet, welcher stirnseitig durch zwei Platten 2 geschlossen ist. Dieser Aufgabebehälter 1 weist eine Beschickungsöffnung 3 auf. In den beiden Stirnplatten 2 des Behälters 1 ist eine Achse 4 gelagert, die aus einer der beiden Stirnplatten 2 nach außen hervorragt. Auf dieses nach außen hervorragende Ende 5 ist ein Hebel 6 fest aufgesetzt, der über eine Kurbelstange 7 mit dem Kurbelzapfen 8 eines Reversierantriebes 9 verbunden ist. Auf diese Weise kann die Achse 4 oszilierend angetrieben werden. Mit der Achse 4 sind mehrere Flügel 10 fest verbunden, wobei die die Flügel 10 als U-förmig gebogene Rahmenausgebildet sind. (Fig. 1) Die Flügel 10 bilden zusammen mit der Achse 4 das eigentliche Einspeiserad 11. Durch dieses Einspeiserad wird das über die Beschickungsöffnung 3 in den Aufgabebehälter 1 eingebrachte Fördergut in die Schneckengänge 12 der Schnecke 13 eingestrichen. Da die Achse 4 parallel zur Schnecke 3 verläuft wird aufgrund der wechselnden Drehrichtung des Einspeiserades 11 die Schnecke 13 von beiden Seiten bestrichen, so daß die Schneckengänge 12 stets gleichmäßig gefüllt werden und gleichzeitig eine Brückenbildung zerstört wird. Die Schnecke 13 ist, wie die Fig. 1 zeigt, über einen Motor 14 angetrieben, dessen Drehzahl bedarfsweise verändert werden kann. In bekannter Weise besteht dabei die Schnecke 13 aus einem wendelförmig gebogenen Draht. Das in Pfeilrichtung A aufgrund unserer Erfindung nun stets in gleicher Menge pro Zeiteinheit bei konstanter Schneckendrehzahl austretende Material gelangt dann zu einer Fülleinrichtung. 1 with a trough-shaped feed container is designated, which is closed at the end by two plates 2 . This feed container 1 has a loading opening 3 . In the two end plates 2 of the container 1 , an axis 4 is mounted, which protrudes outwards from one of the two end plates 2 . A lever 6 , which is connected via a crank rod 7 to the crank pin 8 of a reversing drive 9 , is firmly attached to this outwardly projecting end 5 . In this way, the axis 4 can be driven oscillating. A plurality of wings 10 are fixedly connected to the axis 4 , the wings 10 being designed as a U-shaped frame. ( Fig. 1) The wings 10 together with the axis 4 form the feed wheel 11 . By means of this feed wheel, the conveyed material introduced into the feed container 1 via the loading opening 3 is brushed into the screw flights 12 of the screw 13 . Since the axis 4 runs parallel to the screw 3 , the screw 13 is coated from both sides due to the changing direction of rotation of the feed wheel 11 , so that the screw flights 12 are always filled uniformly and at the same time a bridge formation is destroyed. The screw 13 is, as shown in FIG. 1, driven by a motor 14 whose speed can be changed as needed. In a known manner, the worm 13 consists of a helically bent wire. The material now emerging in the direction of arrow A due to our invention always in the same quantity per unit of time at constant screw speed then reaches a filling device.
