Abstract
Description
Die Erfindung betrifft eine Füllmaschine zum Füllen von offenen Großsäcken mit einem Füllstutzen, an dessen unteren Randbereich der zu füllende Großsack ansetzbar ist, dass im unteren Bereich des Füllstutzens wenigstens ein Verschließelement angeordnet ist, welches mittels eines steuerbaren Stelltriebes in eine die Durchströmöffnung des Füllstutzens freigebende und verschließende Stellung bringbar ist.The invention relates to a filling machine for filling open large sacks with a filler neck, at the bottom of which the large bag to be filled can be attached is that in the lower region of the filler neck at least one closing element is arranged, which by means of a controllable actuator into a through-flow the filling nozzle releasing and closing position can be brought.
Die mittels der in Rede stehenden Füllmaschine zu füllenden Großsäcke werden in der Branche auch als Big Bags bezeichnet. Sie sind aus einem hoch belastbaren Material gefertigt, vorzugsweise aus einem Bändchengewebe. Im Normalfall werden die Großsäcke mit 1000 kg eines Füllgutes gefüllt. Die Abmessungen der Großsäcke richten sich nach dem spezifischen Gewicht bzw. der Wichte des Füllgutes. Es ist nicht zu verhindern, dass sich, vorzugsweise bedingt durch eine statische Aufladung, Füllgut an der Innenfläche des Füllkanals absetzt. Nach Ende des Füllvorganges kommt es während des Abnehmens und Verschließens des Großsackes zu Erschütterungen des Füllstutzens. Die an der Innenfläche des Füllkanals anhaftenden Füllgutpartikel werden dann gelöst, so dass sie auf den noch darunter stehenden Sack fallen. Das nachrieselnde Füllgut kann durchaus ein Gewicht von mehreren Kilogramm ausmachen. Es werden jedoch heute hohe Anforderungen gestellt, insbesondere werden saubere Säcke verlangt. The to be filled by means of the filling machine in question bulk bags are in the industry also referred to as big bags. They are made of a heavy duty material manufactured, preferably from a ribbon fabric. In the normal case will be the large bags filled with 1000 kg of a filling. The dimensions of the large bags depend on the specific weight or the weight of the filling material. It is not to prevent, preferably due to a static charge, Filling material deposits on the inner surface of the filling channel. After the end of the filling process it comes during the removal and closing of the large bag to shock of the filler neck. The adhering to the inner surface of the filling channel Filled particles are then released, so that they are on the still below Sack falling. The nachrieselnde contents can quite a weight of several Make out kilograms. However, there are high demands today, in particular clean bags are required.
Es ist deshalb schon durch die EP 0 709 291 eine Füllmaschine mit den Merkmalen des Oberbegriffs des Anspruchs 1 vorgeschlagen.It is therefore already proposed by EP 0709291 a filling machine with the features of the preamble of claim 1.
Bei dieser Ausführung ist jedoch nicht zu verhindern, dass die Kolbenzylindereinheiten sehr stark mit Staub und Schmutz beaufschlagt werden, da sie ungeschützt angeordnet sind. Bei der vorbekannten Füllmaschine ist deshalb davon auszugehen, dass die Lebensdauer der Kolbenzylindereinheiten gegenüber anderen Einsatzfällen verkürzt wird, da die Dichtelemente durch Staub- und Schmutzeinwirkung einem erhöhten Verschleiß unterliegen.In this embodiment, however, can not prevent the piston-cylinder units be very heavily contaminated with dust and dirt, as they are unprotected are arranged. In the prior art filling machine is therefore assumed that the life of the piston-cylinder units over other applications is shortened, since the sealing elements by dust and dirt a subject to increased wear.
Ausgehend von einer durch die EP 0 709 291 A2 vorbekannten Füllmaschine liegt der Erfindung die Aufgabe zugrunde, die Füllmaschine so zu gestalten, dass die empfindlichen Linearantriebe in einem Bereich angeordnet werden, der nicht besonders hoch mit Staub und Schmutz beaufschlagt wird.Starting from a previously known by EP 0 709 291 A2 filling machine The invention has for its object to make the filling machine so that the sensitive linear actuators are placed in a range that is not particularly highly charged with dust and dirt.
Die gestellte Aufgabe wird gelöst, indem zumindest das Abtriebsglied des Stelltriebes horizontal montiert und über durch den Ringkanal geführte Schwenkgestänge mit dem Verschließelementen antriebstechnisch verbunden ist.The stated object is achieved by at least the output member of the actuator horizontal mounted and guided through the annular channel pivot linkage with the closing elements drive technology is connected.
Der Füllstutzen ist nunmehr doppelwandig ausgebildet, so dass sich an dem Durchströmkanal ein Ringkanal anschließt, wobei in diesem Ringkanal der Stelltrieb bzw. die Stelltriebe angeordnet sind. Dieser Ringkanal dient gleichzeitig zum Absaugen der aus dem sich füllenden Großsack entweichenden Luft. The filler neck is now double-walled, so that at the flow channel an annular channel connects, wherein in this annular channel of the actuator or the adjusting drives are arranged. This ring channel also serves for suction the air escaping from the filling large bag.
In bevorzugter Ausführung kommt als Stelltrieb eine pneumatisch betätigbare Kolbenzylindereinheit in Frage. Da diese im Abstand zur Ausströmöffnung des Füllstutzens stehen, das heißt, sie sind im oberen Bereich des Füllstutzens angeordnet, sind sie so gut wie möglich gegen Staub und Schmutz geschützt.In a preferred embodiment comes as actuator a pneumatically actuated piston-cylinder unit in question. Since these are at a distance from the discharge opening of the filling nozzle stand, that is, they are located in the upper part of the filling nozzle, they are as well protected as possible against dust and dirt.
Jedes Verschließelement besteht zweckmäßigerweise aus zwei Verschlussklappen, die um zwei horizontale, parallel und im Abstand zueinander stehende Achsen verschwenkbar sind. Das aus zwei Verschlussklappen bestehende Verschließelement bietet den Vorteil, dass in bevorzugter Ausführung durch jede Verschlussklappe nur die halbe Auslauföffnung bzw. der halbe Querschnitt des Durchströmkanals verschlossen werden muss, so dass die Verschlussklappen auch dann noch oberhalb des Füllgutspiegels im geöffneten Zustand stehen, wenn das Gewicht des Sackes erreicht ist, da eine bestimmte Länge für den Verschluss des gefüllten Großsackes notwendig ist. Der Durchströmkanal des Füllstutzens ist in bevorzugter Ausführung kreisrund. Sofern das Verschlusselement aus zwei Verschlussklappen besteht, ist es sinnvoll, wenn diese von der Größer her gleich oder annähernd gleich sind und dass sie demzufolge halbkreisförmig oder annähernd halbkreisförmig gestaltet sind.Each closing element expediently consists of two closing flaps, the two horizontal, parallel and spaced axes are pivotable. The closing element consisting of two flaps offers the advantage that in a preferred embodiment by each flap only half the outlet opening or half the cross section of the flow channel must be closed, so that the flaps still stand above the level of the contents in the opened state, if the weight of the Sackes is reached as a certain length for the closure of the filled large bag necessary is. The flow channel of the filler neck is in a preferred embodiment circular. If the closure element consists of two flaps, does it make sense if they are the same or almost the same in size? and that they are therefore semicircular or approximately semicircular are.
Damit kein Material durch die Fuge im geschlossenen Zustand der Verschlussklappen fällt, ist vorgesehen, dass sich die den Stelltrieben abgewandten Kanten ein klein wenig überlappen. Dies lässt sich konstruktiv in einfachster Weise durchführen, wenn an eine der Verschlussklappen eine Leiste angesetzt ist, die gegenüber der Ebene der Verschlussklappe verspringt. Sofern der Füllstutzen mit zwei Verschlussklappen ausgerüstet ist, ist vorgesehen, dass jedes Verschließelement mittels eines eigenen Stelltriebes, vorzugsweise mittels eines Linearantriebes, betätigbar ist. Vorteilhaft ist, wenn die äußere Wandung des Füllstutzens zumindest im unteren Bereich als ein mit Druckluft beaufschlagbarer Blähschlauch ausgebildet ist. Nach dem Anlegen des oberen Randes des Großsackes wird dieser Blähschlauch dann mit Druckluft beaufschlagt und aufgeweitet, so dass der obere Sackrand gegen eine die Sackschnalle enthaltendes Widerlager gedrückt wird. Zum Abnehmen des gefüllten Sackes wird der Blähschlauch entlüftet und die Sackschnalle geöffnet.So no material through the joint in the closed state of the flaps falls, it is provided that the actuators facing away from the edges little bit overlapping. This can be constructively carried out in the simplest way, if at one of the flaps a bar is attached, the opposite the level of the flap leaps. If the filler neck with two flaps is equipped, it is provided that each closing element means a separate actuator, preferably by means of a linear actuator, operable is. It is advantageous if the outer wall of the filler neck, at least in the lower Range is designed as a pressurizable air pressure inflatable tube. After applying the upper edge of the large bag, this inflatable tube then pressurized with air and expanded, so that the upper edge of the bag against a sack buckle containing abutment is pressed. To lose weight filled bag, the inflatable tube is vented and the bag buckle opened.
Zweckmäßigerweise ist der Füllstutzen um eine Horizontalachse schwenkbar, die im Abstand zur Ausströmöffnung des Füllstutzens steht. Dadurch kann der zu füllende Großsack sinngemäß seitlich und von unten auf den Füllstutzen aufgesteckt und mittels der Sackschnalle festgelegt werden. Damit eine Schwenkbewegung ungehindert durchgeführt werden kann, ist vorgesehen, dass die Horizontalachse seitlich neben dem Füllstutzen liegt, vorzugsweise angrenzend an die Außenwand. Der Bedienkomfort wird noch wesentlich erhöht, wenn der Füllstutzen mittels eines Stelltriebes schwenkbar ist. Dieser Stelltriebe enthält wenigstens eine Kolbenzylindereinheit. Die Schwenkbewegung kann in Abhängigkeit von der Stellung der Verschlussklappen erfolgen. So könnte der Füllstutzen in die Schrägstellung gefahren werden, wenn die Verschlussklappen geschlossen sind. Sobald der Großsack mittels der Sackschnalle festgelegt ist, könnte der Füllstutzen wieder in die normale vertikale Füllstellung gefahren werden. Conveniently, the filler neck is pivotable about a horizontal axis, the is at a distance to the discharge opening of the filler neck. This allows the to be filled Large bag is attached laterally and from below onto the filler neck and be fixed by means of the bag buckle. So that a pivoting movement unhindered can be performed, it is provided that the horizontal axis laterally adjacent to the filler neck, preferably adjacent to the outer wall. Of the Ease of use is significantly increased when the filler neck by means of a Stelltrieb is pivotable. This actuator includes at least one piston-cylinder unit. The pivoting movement may be dependent on the position of the shutters respectively. So the filler neck could be driven into the oblique position when the flaps are closed. Once the big bag by means of the sack buckle is fixed, the filler neck could return to the normal vertical Filling be driven.

Der in der Figur 1 dargestellte Füllstutzen 10 enthält einen Durchströmkanal 11, der
im Querschnitt kreisrund ausgebildet ist. Das Füllgut wird von einer nicht dargestellten,
oberhalb des Füllstutzens 10 angeordneten Waage ausgeschüttet. Der Füllgutstrom
wird von einer nicht dargestellten Dosiereinrichtung gesteuert. Der Füllstutzen
10 ist mit einer den Durchströmkanal 11 begrenzenden Innenwandung 12
und einer Außenwandung 13 begrenzt, wobei zwischen der Innenwand 12 und der
Außenwand 13 ein Ringkanal 14 liegt. Am unteren, der Ausströmöffnung des
Durchströmkanals 11 zugeordneten Seite sind zwei um horizontale Achsen 15, 16
schwenkbare Verschlußklappen 17, 18 montiert. Die Verschlußklappen sind von
der in der Figur 1 dargestellten Offenstellung mittels Stelltriebe bildenden Kolbenzylindereinheiten
19, 20 in eine Verschlußstellung schwenkbar. Dies erfolgt unmittelbar
nach Ende des Füllvorganges und vor dem Abnehmen des nicht dargestellten
gefüllten Großsackes. Die Ausströmöffnung wird dadurch vollständig verschlossen,
so dass durch Erschütterungen sich von der Innenwand 12 lösendes Füllgut durch
die Verschlußklappen 17, 18 zurückgehalten wird. Damit im mittleren Bereich keine
Fuge entsteht, ist gemäß der Ausführung nach der Figur 1 die in der Darstellung
linke Verschlußklappe 17 an der Außenseite mit einer Leiste 21 ausgestattet, die die
Trennfuge im geschlossenen Zustand der Verschlußklappen 17, 18 übergreift. Die
Steuerung der Kolbenzylindereinheiten 19, 20 muß darauf abgestimmt sein, das
heißt, die in der Darstellung rechte Verschlußklappe 18 muß ein klein wenig früher
in die Verschlußlage geschwenkt werden. Im dargestellten Ausführungsbeispiel
sind die Kolbenzylindereinheiten 19, 20 so montiert, dass die Kolbenstangen in
unmittelbarer Nähe der horizontalen Achsen 15, 16 stehen. Entgegen der Darstellung
ist es zweckmäßig, wenn die Kolbenzylindereinheiten 19, 20 im oberen Bereich
des Füllstutzens 10 montiert werden, da sie dann nicht einer so hohen Belastung
durch die Staubentwicklung ausgesetzt werden. Die Verbindung mit den Verschlußklappen
17, 18 erfolgt dann über entsprechend ausgelegte Gestänge.The
Im dargestellten Ausführungsbeispiel ist der untere Bereich der äußeren Wandung
13 als Blähschlauch 13a ausgebildet, der nach dem Anlegen des leeren Großsackes
durch Beaufschlagung mit Druckluft aufgeweitet wird, so dass der Sackrand gegen
ein ringförmiges Widerlager 22 gedrückt wird, welches auch die Sackschnalle 23
enthält. Durch die Aufweitung des Blähschlauches 13a wird der Sack in Verbindung
mit dem Widerlager 22 festgelegt. Die Verschlußklappen 17, 18 werden bevorzugt
in die Offenstellung geschwenkt, nachdem der an den Füllstutzen 10 angehängte
Großsack aufgeblasen wurde, da die Verschlußklappen 17, 18 das Aufblasen
begünstigen. Die Verschlußklappen 17, 18 werden in die Schließstellung geschwenkt,
nachdem entweder der Blähschlauch 13a drucklos ist oder wenn die
Sackschnalle geöffnet wird. Entgegen der Darstellung nach der Figur 1 können die
Stelltriebe 19, 20 bzw. die Kolbenzylindereinheiten auch im oberen Bereich oder
auch oberhalb des Füllstutzens 10 angeordnet werden. Zweckmäßigerweise werden
sie dann horizontal montiert. Sie sind über eine allgemein bekanntes Schwenkgestänge
antriebstechnisch mit den Verschlußklappen 17, 18 verbunden. Die Stelltriebe
19, 20 sind dann so gut wie es möglich ist, gegen eine Staub- und Schmutzbelastung
geschützt.In the illustrated embodiment, the lower portion of the
