Abstract

The filling apparatus for a powdery product, especially for a freeze-dried food product, has a container conveyor for a plurality of containers, a measuring device and a plurality of filling funnels which are placed in the containers. The container conveyor has an entrance portion with a feed belt, a filling zone adjoining it and a delivery belt. A plurality of filling funnels is attached to a continuously circulating chain conveyor and guided in the conveying direction on the forwardly moving strand of a chain conveyor above and close to the container conveyor. A conveying screw driven synchronously with the chain conveyor is located in the entrance portion of the conveying belt. Its conveying helix engages the containers laterally so that the containers are movable with a feed speed corresponding to the conveying speed of the chain conveyor and can be spaced as defined in the spacing between the outlets of the filling funnels. A feeder-weigher used as the measuring device is located in the vicinity of the filling zone above the container conveyor. A continuous product flow is fed to the containers moving past with the conveying speed.

Description

Die Erfindung bezieht sich gattungsgemäß auf eine Abfüllvorrichtung für pulverförmige Produkte, insbesondere für gefriergetrocknete Lebensmittel, - mit Transportbahn für Behälter, Dosiereinrichtung sowie auf die Behälter aufsetzbaren Fülltrichtern, wobei die Transport­bahn einen Einlaufbereich mit Transportband, eine daran anschließende Füllzone sowie ein Abtransportband aufweist.The invention generally relates to a filling device for powdery products, in particular for freeze-dried food, with a transport path for containers, dosing device and filling funnels which can be placed on the containers, the transport path having an inlet area with a conveyor belt, an adjoining filling zone and a discharge belt.

Die aus der Praxis bekannte gattungsgemäße Abfüllvorrichtung ist mit pneumatisch absenkbaren Fülltrichtern ausgebildet und arbeitet taktweise. Als Dosiereinrichtungen sind zumeist Behälterwaagen eingesetzt. Die Füllgeschwindigkeit ist im Rahmen der bekannten Maßnahmen unbefriedigend, und zwar auch dann, wenn - wie in der Praxis üblich - eine Mehrzahl von Behältern gleichzeitig mit einer Produktmenge gefüllt werden. Auch hinsichtlich der Steuerung sind die bekannten Vorrichtungen aufwendig.The generic filling device known from practice is designed with pneumatically lowerable filling funnels and operates in cycles. Container scales are mostly used as dosing devices. The filling speed is unsatisfactory in the context of the known measures, even if - as is usual in practice - a plurality of containers are filled with a product quantity at the same time. The known devices are also complex in terms of control.

Die Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Abfüllvorrichtung für pulverförmige Produkte anzugeben, mit der ein Abfüllen bei kontinuierlichem Durchlauf der Behälter möglich ist.The invention has for its object to provide a generic filling device for powdered products, with which a filling is possible with a continuous flow of the container.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß eine Vielzahl von Fülltrichtern an einem kontinuierlich umlaufenden Kettenförderer angeschlossen und im Vorlauftrum des Kettenförderers dicht an dicht oberhalb der Transportbahn in Transportrichtung geführt sind, daß im Einlaufbereich der Transportbahn ein mit dem Kettenförderer synchron betriebener Schneckenförderer angeordnet ist, dessen Transportwendeln die Behälter seitlich fassen, wobei die Behälter mit einer der Transportgeschwindigkeit des Kettenförderers entsprechenden Vorschubgeschwindigkeit mitführbar und nach Maßgabe des Abstandes zwischen den Austrittsöffnungen der Fülltrichter distanzierbar sind, daß die von den Fülltrichtern gebildete Bahn und die Transportbahn im Einlaufbereich sowie im Bereich des Abtransportbandes schräg zueinander angeordnet sind, wobei die Fülltrichter bei kontinuierlicher Transportbewegung mit der Austritts­öffnung in die Behälter einführbar sowie schließlich wieder ausführbar sind, daß oberhalb der Transportbahn im Bereich der Füllzone eine Bandwaage als Dosiereinrichtung angeordnet ist, wobei ein kontinuierlicher Produktstrom auf die mit der Transportgeschwindigkeit vorbeigeführten Behälter aufgebbar ist. Es versteht sich, daß die Bandwaage regel- und steuerungstechnische Einrichtungen enthält, die den Produktstrom entsprechend einem vorgebbaren Sollwert steuern. Im Rahmen der Erfindung liegt es, daß die Band­waage an eine Steuerung angeschlossen ist, die den Füllgrad in den Behältern überwacht und bei Abweichungen den Sollwert entsprechend korrigiert. Ebenso liegt es im Rahmen der Erfindung, daß die Steuerung den Sollwert für den Produktstrom mit der Transport­geschwindigkeit des Kettenförderers koppelt und auf diese Weise eine Synchronisierung herstellt. Nach bevorzugter Ausführungsform der Erfindung weist der Kettenförderer eine horizontal um Kehren geführte Kette auf, an die die Fülltrichter einseitig angeschlossen sind. In diesem Falle ist die Transportbahn im Einlaufbereich sowie im Bereich des Abtransportbandes um einen Einlauf- sowie Auslaufwinkel schräg angeordnet. Die genaue Einhaltung äquidistanter Abstände zwischen den Austrittsöffnungen der Fülltrichter ist insbe­sondere gegeben, wenn die Fülltrichter sich gegeneinander abstützen. Zweckmäßigerweise ist an den Rücklauftrum des Kettenförderers eine Rüttelvorrichtung angeschlossen, um durch Vibration die Fülltrichter von anhaftenden Produktresten zu reinigen. Es empfiehlt sich fernerhin, die Transportbahn im Bereich der Füllzone als eine mit Unwuchtantrieb ausgebildete Vibrationsstrecke auszuführen. Auf diese Weise kann eine gute Verdichtung des in die Behälter eingefüllten Produktes und hohes Schüttgewicht erreicht werden. Im Rahmen der Erfindung liegt es, die Vibrationsstrecke auch zwei oder mehrteilig mit individuell regelbaren Abschnitten auszubilden. Bei der praktischen Ausführung sollte der Kettenförderer schließlich auch eine Abdeckung aufweisen mit einer die Fülltrichter im Bereich der Füllzone freigebenden Aussparung. Die oberhalb des Kettenförderers angeordnete Produktzufuhr und Dosiereinrichtung kann dabei zumindest ein Teil der Abdeckung darstellen. Es versteht sich fernerhin, daß der Antrieb der Abfüllvorrichtung zweckmäßigerweise über einen stufenlos regelbaren Zentralantrieb erfolgt. Schließlich kann der Abfüllvorrichtung eine Weiche nachgeschaltet sein, die über eine Steuerung betätigbar ist und bei jedem Maschinenanlauf die ersten, nicht gefüllten Behälter ausschleust.The solution to this problem is according to the invention that a large number of filling funnels are connected to a continuously rotating chain conveyor and are guided in the forward run of the chain conveyor close to just above the transport path in the transport direction, that a screw conveyor operated synchronously with the chain conveyor is arranged in the inlet region of the transport path, whose helices transport the container laterally, whereby the containers can be carried along at a feed speed corresponding to the transport speed of the chain conveyor and can be spaced apart in accordance with the distance between the outlet openings of the filling funnels, that the path formed by the filling funnels and the transport path are arranged obliquely to one another in the infeed area and in the area of the removal belt, the filling funnels at Continuous transport movement with the outlet opening can be introduced into the container and finally can be carried out again in that a belt weigher is arranged as a metering device above the transport path in the area of the filling zone, a continuous product flow being able to be applied to the containers carried past at the transport speed. It goes without saying that the belt scale contains regulating and control technology devices which control the product flow in accordance with a predefinable setpoint. It is within the scope of the invention that the belt scale is connected to a controller that monitors the degree of filling in the containers and corrects the target value accordingly in the event of deviations. It is also within the scope of the invention for the control to couple the setpoint for the product flow to the transport speed of the chain conveyor and to establish a synchronization in this way. According to a preferred embodiment of the invention, the chain conveyor has a chain which is guided horizontally around bends and to which the filling funnels are connected on one side. In this case, the transport path in the infeed area and in the area of the discharge belt is arranged obliquely by an infeed and outfeed angle. The exact observance of equidistant distances between the outlet openings of the filling funnels is given in particular if the filling funnels are supported against one another. A vibrator is expediently connected to the return run of the chain conveyor in order to vibrate the Clean funnel from adhering product residues. It is also advisable to design the transport path in the area of the filling zone as a vibration path designed with an unbalance drive. In this way, good compression of the product filled into the container and high bulk density can be achieved. It is within the scope of the invention to design the vibration path in two or more parts with individually controllable sections. In the practical embodiment, the chain conveyor should finally also have a cover with a recess which exposes the filling funnels in the region of the filling zone. The product feed and metering device arranged above the chain conveyor can represent at least part of the cover. It also goes without saying that the filling device is expediently driven by a continuously variable central drive. Finally, a switch can be connected downstream of the filling device, which can be actuated by a control and which ejects the first, non-filled containers each time the machine is started up.

Die Vorteile der Erfindung sind darin zu sehen, daß aufgrund des kontinuierlichen Durchlaufs der zu füllenden Behälter durch die Abfüllvorrichtung eine hohe Füllgeschwindigkeit erreichbar ist, und zwar ohne aufwendige, beispielsweise mit pneumatischen Bauteilen versehene, Steuerung.The advantages of the invention can be seen in the fact that, due to the continuous passage of the containers to be filled through the filling device, a high filling speed can be achieved, and indeed without complex control, for example provided with pneumatic components.

Im folgenden wird die Erfindung anhand einer lediglich ein Ausfüh­rungsbeispiel darstellenden Zeichnung ausführlicher erläutert. Es zeigen in schematischer Darstellung

  • Fig. 1 eine erfindungsgemäße Abfüllvorrichtung in der Draufsicht, jedoch ohne Dosiereinrichtung,
  • Fig. 2 eine Seitenansicht gemäß A in Fig. 1,
  • Fig. 3 eine Seitenansicht gemäß B in Fig. 1.
In the following, the invention will be explained in more detail with reference to a drawing showing only one embodiment. They show a schematic representation
  • 1 is a top view of a filling device according to the invention, but without a metering device,
  • 2 is a side view according to A in Fig. 1,
  • 3 shows a side view according to B in FIG. 1.

Die in den Figuren dargestellte Abfüllvorrichtung ist für pulverförmige Produkte, insbesondere für gefriergetrocknete Lebensmittel, bestimmt. Zum grundsätzlichen Aufbau der Abfüllvorrichtung gehören eine Transportbahn 1 für Behälter 2, eine Dosiereinrichtung 3 sowie auf die Behälter 2 aufsetzbare Fülltrichter 3. Die Transportbahn 1 weist einen Einlaufbereich E mit Transportband 5, eine daran anschließende Füllzone F sowie ein Abtransportband 6 auf. Die Fülltrichter 4 sind an einen kontinuierlich umlaufenden Kettenförderer 7 angeschlossen und im Vorlauftrum 8 des Kettenförderers 7 dicht an dicht oberhalb der Transportbahn 1 in Transportrichtung geführt. Der Kettenförderer 7 ist im Ausführungsbeispiel horizontal angeordnet und weist eine um Kehren 9 geführte Kette 10 auf, an die die Fülltrichter 4 mit Anschlußstutzen 11 einseitig angeschlossen sind. Dabei stützen sich die Fülltrichter 4 im Vorlauftrum 8 gegeneinander ab. Es versteht sich, daß der Kettenförderer motorisch antreibbar ist von einem nicht dargestellten Antriebsaggregat.The filling device shown in the figures is intended for powdery products, in particular for freeze-dried foods. The basic structure of the filling device includes a transport path 1 for containers 2, a metering device 3 and filling funnels 3 which can be placed on the containers 2. The filling funnels 4 are connected to a continuously rotating chain conveyor 7 and are guided in the forward run 8 of the chain conveyor 7 close to each other above the transport path 1 in the transport direction. The chain conveyor 7 is arranged horizontally in the exemplary embodiment and has a chain 10 guided around bends 9, to which the filling funnels 4 with connecting pieces 11 are connected on one side. The filling funnels 4 are supported against each other in the forward run 8. It is understood that the chain conveyor can be driven by a motor drive unit, not shown.

Aus einer vergleichenden Betrachtung der Fig. 1 und 2 erkennt man, daß im Einlaufbereich E der Transportbahn 1 ein mit dem Kettenförderer 7 synchron betriebener Schneckenförderer 12 angeordnet ist, um die dicht an dicht ankommenden Behälter 2 auf den in der Füllzone F einzuhaltenden Abstand a zu bringen. Man erkennt, daß die Transportwendeln 13 des Schneckenförderers 12 die Behälter 2 seitlich fassen. Dadurch sind die Behälter 2 mit einer der Transportge­schwindigkeit v des Kettenförderers 7 entsprechenden Vorschubgeschwin­ digkeit mitführbar und nach Maßgabe des Abstandes a zwischen den Austrittsöffnungen 14 der Fülltrichter 4 distanzierbar. Wie aus der Fig. 2 ersichtlich, ist die Transportbahn 1 im Einlaufbereich E um einen Einlaufwinkel α schräg angeordnet. Durch die Einlaufschräge sind die Fülltrichter 4 bei kontinuierlicher Transportbewegung mit der Austrittsöffnung 14 in die Behälter 2 einführbar. Es versteht sich, daß die Austrittsöffnungen 14 der Fülltrichter 4 als Zentrierungen ausgebildet sind. Der Fig. 3 entnimmt man, daß die Transportbahn 1 auch im Bereich des Abtransportbandes 6 um den Winkel α schräg angeordnet ist und durch das Absenken des Abtransportbandes 6 in Transportrichtung die nunmehr gefüllten Behälter 2 im kontinuier­lichen Lauf aus den Zentrierungen der Fülltrichter 4 herausführbar sind.From a comparative view of FIGS. 1 and 2 it can be seen that a screw conveyor 12 operated synchronously with the chain conveyor 7 is arranged in the inlet region E of the transport path 1 in order to close the tightly arriving containers 2 to the distance a to be observed in the filling zone F. bring. It can be seen that the transport coils 13 of the screw conveyor 12 grip the containers 2 laterally. As a result, the containers 2 are at a feed rate corresponding to the transport speed v of the chain conveyor 7 can be carried along and can be spaced apart in accordance with the distance a between the outlet openings 14 of the filling funnel 4. As can be seen from FIG. 2, the transport path 1 is arranged obliquely in the entry area E by an entry angle α. Through the inlet slope, the hopper 4 can be inserted into the container 2 with the outlet opening 14 during a continuous transport movement. It is understood that the outlet openings 14 of the hopper 4 are designed as centering. 3 shows that the conveyor track 1 is also arranged obliquely in the region of the conveyor belt 6 by the angle α and that by lowering the conveyor belt 6 in the direction of transport the now filled containers 2 can be guided out of the centering of the hopper 4 in a continuous run.

Im Bereich der Füllzone F ist oberhalb der Transportbahn 1 eine Bandwaage 3 als Dosiereinrichtung angeordnet (Fig. 2). Mit der Bandwaage 3 ist ein kontinuierlicher Produktstrom auf die mit der Transportgeschwindigkeit v vorbeigeführten Behälter 2 mit aufgesetzten Trichtern 4 aufgebbar. Die Bandwaage 3 ist in bekannter Weise mit Steuerungs- und Regelungseinrichtungen ausgerüstet, die den Produktstrom entsprechend einem vorgebbaren Sollwert steuern. Zweckmäßigerweise ist die Bandwaage 3 fernerhin an eine Steuerung angeschlossen, die den Füllgrad in den Behältern überwacht und bei Abweichungen von einem vorgegebenen Wert den Sollwert für den Produktstrom entsprechend korrigiert. Die Transportbahn 1 ist im Bereich der Füllzone F im übrigen als eine mit Unwuchtantrieb ausgebildete Vibrationsstrecke 15 ausgeführt, und zwar mit zwei individuell einstellbaren Streckenabschnitten 15a, 15b. Durch die Vibrationsstrecke 15 ist eine gute Verdichtung des in die Behälter 2 eingefüllten Produktes erreichbar. Schließlich erkennt man aus Fig. 1, daß an den Rücklauftrum 16 des Kettenför­ derers 7 eine Rüttelvorrichtung 17 - im Ausführungsbeispiel durch ein Blechgehäuse verkleidet - angeschlossen ist, um die Fülltrichter von anhaftenden Produktresten zu befreien.In the area of the filling zone F, a belt scale 3 is arranged as a metering device above the conveyor track 1 (FIG. 2). With the belt scale 3, a continuous product stream can be fed onto the containers 2 with the funnels 4 placed on at the transport speed v. The belt scale 3 is equipped in a known manner with open-loop and closed-loop control devices which control the product flow in accordance with a specifiable setpoint. Conveniently, the belt scale 3 is also connected to a controller that monitors the degree of filling in the containers and corrects the target value for the product flow accordingly in the event of deviations from a predetermined value. In the area of the filling zone F, the transport path 1 is also designed as a vibration path 15 designed with an unbalance drive, with two individually adjustable path sections 15a, 15b. A good compression of the product filled into the container 2 can be achieved by the vibration path 15. Finally, it can be seen from Fig. 1 that the return run 16 of the chain conveyor 7 of which a vibrating device 17 - in the exemplary embodiment covered by a sheet metal housing - is connected in order to free the filling funnel from adhering product residues.
