Description

Die Erfindung betrifft ein Verfahren zum Öffnen und Verschließen eines Behälters.The invention relates to a method for opening and closing a container.

Ein derartiges Verfahren ist aus der FR-A-2 260 522 bekannt und arbeitet gänzlich nach dem Schwerkraftprinzip. Will man ein derartiges Verfahren z. B. in die Materialversorgung von Kunststoffspritzgießmaschinen integrieren, so ist daran nachteilig, daß die Verschlußklappe häufig nicht vollständig schließt, insbesondere wenn sich das Fließverhalten der Materialien problematisch gestaltet.Such a method is known from FR-A-2 260 522 and works entirely according to the Principle of gravity. If you want such a method z. B. in the material supply of Integrating plastic injection molding machines, it is disadvantageous that the closure flap often does not close completely, especially if the flow behavior of the materials changes designed problematic.

Weiter ist ein derartiges Verfahren aus der DE-C-462 875 bekannt und arbeitet über eine Zwangskopplung an ein nachgeordnetes Förderband.Such a method is also known from DE-C-462 875 and works via a Forced coupling to a downstream conveyor belt.

Man könnte nun eine aufwendige Funktionssteuerung über Sensoren und Antriebe vorsehen. Dies ist aber kostenaufwendig, es würde das Verfahren verteuern.One could now provide complex function control via sensors and drives. However, this is costly and would make the process more expensive.

Es ist somit Aufgabe der Erfindung, ein Verfahren bzw. eine Vorrichtung zur Durchführung desselben der eingangs genannten Art dahingehend zu verbessern, daß ein einfach anzuwendendes, billiges und sicher arbeitendes Verfahren bzw. eine Vorrichtung zur Durchführung geschaffen wird.It is therefore an object of the invention to provide a method and an apparatus for carrying it out the same of the type mentioned to improve that a simple to be used, cheap and safe working method or an apparatus for Implementation is created.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine an wenigstens einem Hebelmechanismus befestigte Klappe durch ein am entgegengesetzten Ende des Hebelmechanismus angebrachtes Gegengewicht in Schließstellung gebracht wird, wobei wenigstens ein an der den Hebelmechanismus lagernden Welle angebrachtes Antriebselement mittels eines an einem Ende der Welle angebrachten Teilfreilaufs bzw. einer bedingten Zwangsführung das Verschließen unterstützt, wenn die Klappe die Schließstellung noch nicht erreicht hat, nach Beendigung der Befüllung des Behälters gibt der Teilfreilauf bzw. die bedingte Zwangsführung über das Antriebselement den Weg zum Öffnen des Behälters frei, so daß durch das auf der Klappe liegende Material die Klappe geöffnet wird.According to the invention, this object is achieved in that one on at least one Lever mechanism attached by a flap at the opposite end of the Lever mechanism attached counterweight is brought into the closed position, whereby at least one drive element attached to the shaft supporting the lever mechanism by means of a partial freewheel attached to one end of the shaft or a conditional one Positive guidance supports the closing if the flap is not yet in the closed position has reached, after completing the filling of the container, the partial freewheel or the conditional guidance via the drive element clears the way to open the container, so that the flap is opened by the material lying on the flap.

Der Bewegungsmechanismus der Klappe wird hauptsächlich durch die Schwerkraft des im Behälter befindlichen Fördergutes bzw. des Gegengewichtes betätigt. Sollte durch Materialrückstände auf der Klappe das Schließen nicht restlos erfolgen, so wirkt das Antriebselement über die bedingte Zwangsführung unterstützend am Schließvorgang mit. Sollten Materialrückstände ein vollständiges Abdichten des Behälters verhindern, so wirkt die bedingte Zwangsführung samt Antriebselement unterstützend am Rückhalten des Materials im Behälter mit.The movement mechanism of the flap is mainly caused by the gravity of the Conveyed material located in the container or the counterweight actuated. Should by Material residues on the flap are not completely closed, this is how it works Drive element via the conditional positive guidance to support the closing process. If material residues prevent the container from being completely sealed, this will work conditional guidance including drive element to support the retention of the material in the container with.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Schaltung des Antriebselements parallel zu einem Funktionsventil geschieht.An advantageous development of the invention provides that the circuit of the Drive elements happens parallel to a function valve.

Ein derartiges vorhandenes Funktionsventil (Quetschventil, Umschaltventil oder Abreinigungsventil), das im Ablauf z. B. der Förderung von Material in den Behälter beteiligt ist, verursacht keine Extrakosten, und dessen Ansteuersignal kann in einfacher Weise dazu benutzt werden, besagtes Antriebselement zu steuern.Such an existing function valve (pinch valve, changeover valve or Cleaning valve), the z. B. involved in the promotion of material in the container causes no extra costs, and its control signal can easily be added are used to control said drive element.

Eine Vorrichtung zur Durchführung des Verfahrens wird in Anspruch 3 insoweit aufgezeigt, daß sie wenigstens einen Hebelmechanismus aufweist, an dessen einem Ende eine Klappe angebracht ist, und daß wenigstens ein Antriebselement an einem Ende der den Hebelmechanismus lagernden Welle angebracht ist, wobei die den Hebelmechanismus lagernde Welle einen Teilfreilauf bzw. eine bedingte Zwangsführung aufweist. An apparatus for performing the method is shown in claim 3 to the extent that that it has at least one lever mechanism, at one end a flap is attached, and that at least one drive element at one end of the Lever mechanism bearing shaft is attached, which is the lever mechanism bearing shaft has a partial freewheel or a conditional positive control.

Eine vorteilhafte Weiterbildung sieht vor, daß am der Klappe entgegengesetzten Hebelmechanismus ein verstellbares Gegengewicht angebracht ist.An advantageous development provides that on the flap opposite lever mechanism an adjustable counterweight is appropriate.

Der Vorteil hierbei liegt in der Möglichkeit, verschiedenartige Stellkräfte zu realisieren.The advantage here is the possibility of different types Actuators to realize.

Weiterhin kann man in vorteilhafter Weise vorsehen, daß die Welle über einen Teilfreilauf bzw. eine bedingte Zwangsführung mit dem Antriebselement verbunden ist.Furthermore, one can advantageously provide that the shaft via a partial freewheel or a restricted positive guidance with the Drive element is connected.

Dies gewährleistet eine hundertprozentige Durchführungssicherheit. Neigt das Fördermaterial nicht zu Brückenbildungen etc., so arbeitet die Vorrichtung nach dem Schwerkraftprinzip, sollten sich Fließverhaltensstörungen mit dem Ergebnis einstellen, daß Materialreste auf der Klappe liegenbleiben, so sorgt das Antriebselement über seinen Teilfreilauf bzw. seine bedingte Zwangsführung, daß in entsprechenden Zeitabschnitten das Fließen bzw. das Öffnen garantiert ist.This ensures one hundred percent Execution security. The material is not sloping Bridge formation etc., so the device works according to the Gravity principle, should flow behavior disorders with the Set result that material remains on the flap remain there, the drive element takes care of its Partial freewheel or its conditional forced operation that in corresponding periods of time flow or opening is guaranteed.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous further developments result from the Subclaims.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor.

Die Halterungsplatine 1 befestigt Hebelmechanismus 2, der verbunden ist mit Teilfreilauf bzw. Zwangsführungselement 3 und 4 sowie Bolzen 8 und Antriebselement 9, am Behälter 5.The mounting plate 1 attaches lever mechanism 2, the is connected to partial freewheel or positive guide element 3 and 4 and bolt 8 and drive element 9 on the container 5.

Klappe 7, die am Hebelmechnismus 2 befestigt ist, wird über Gegengewicht 6 durch Schwerkraft geschlossen. Zum öffnen der Klappe 7 dreht das Antriebselement 9 voraneilend das Teilfreilaufs- bzw. bedingte Zwangsführungselement 3 in eine Stellung, in der die Klappe 7 mittels Hebelmechanismus 2 durch das ansteigende Gewicht von gefördertem Granulat auf der Klappe 7 wiederum nach dem Schwerkraftprinzip das Granulat freigibt. Danach schließt sich die Klappe wiederum nach dem Schwerkraftprinzip über das am Hebelmechanismus 2 befestigte Gegengewicht 6. Sollten nun Granulatreste u. ä. auf der Klappe ein restloses Verschließen verhindern, so unterstützt das Antriebselement 9, welches über ein im Prozeß verwendetes Funktionsventil (Quetsch-, Umschalt- oder Abreinigungsventil) parallel geschaltet wird, über Teilfreilauf bzw. Zwangsführungselemente 3 und 4 den Schließvorgang.Flap 7, which is attached to the lever mechanism 2, is about Counterweight 6 closed by gravity. To open the Flap 7 rotates the drive element 9 leading Partial freewheel or conditional guidance element 3 in one Position in which the flap 7 by means of lever mechanism 2 the increasing weight of conveyed granules on the flap 7 again releases the granules according to the principle of gravity. Then the flap closes again after the Gravity principle on the attached to the lever mechanism 2 Counterweight 6. If granulate remains u. on the flap Preventing a complete closure, this helps Drive element 9, which has a used in the process Function valve (pinch, changeover or cleaning valve) is switched in parallel, via partial freewheel or Forced guidance elements 3 and 4 the closing process.
