Definitions
- the invention relates to a device for filling sacks with the initially flat sacks in the region of the side edges of their opening edges, with clamping devices which engage on opposite sides in the region of the opening edges and pull them up and with a filler neck.
- the object of the invention is therefore to provide a device of the type specified at the outset in which the adherence of dust-like filling material to the sack walls in the region of the attack of the suction devices is avoided.
- this object is achieved in a device of the generic type in that at least underneath the suction device or the eggs on each side of the suction device carriers there is a transverse strip made of elastomeric material, which presses the opened edge regions of the bags sealingly against the side walls of the filling funnel .
- the suction cup carriers are thus assigned a double function, namely that of carrying and moving the suction cups and, on the other hand, that of the carrier for transverse sealing strips.
- the suction cups provided with the sealing strips are controlled and moved by their drives after the sack edges have been opened by the suction cups in such a way that the sealing strips are pressed against the walls of the filler neck after it has been retracted.
- the sealing strips thus protect the inner walls in the area on which the suction cups have attacked or have been attacked from rising dust-like filling material, so that this cannot accumulate on the areas of the bag walls which are electrostatically charged by the elevator process.
- the sealing strips are wider than the suction cups and the suction cups are arranged in a recess in the strips.
- the sealing strip completely surrounds the suction cups, so that the areas of the bag wall, on which the suction cups have or have attacked, can be pressed against the walls of the filling funnel and thus also protected against the entry of dusty filling material ascending are when the sealing strips with the remaining parts of the hopper should not completely seal the filling opening of the sack.
- filling funnels of the type known, for example, from EP-OS 82 955 with filling funnel halves which can be pivoted in opposite directions about axes parallel to one another and transversely to the line connecting the clamping devices, of which each filling funnel half has a U-shaped cross-section and which through which U-legs formed and parallel to their swivel plane side walls overlap each other in their swung-out position, provided according to the invention that the strips in the area of the edges of the overlapping side walls of the filling funnel halves are provided with steps such that the drawn-up edge regions of the bags through the strips close to the overlapping side walls of the hopper halves can be pressed.
- the filling funnel can be connected closely to the opening edge of the sacks to be filled due to the pivoting-out filling funnel halves.
- a gap can still form between the overlapping edge regions of the side walls of the filling funnel halves, emerge through the dust-like filling material and can accumulate on the areas of the bag wall which are statically charged by the suction movements. If the sealing strips do not have sufficient elasticity and resilience to bridge the steps formed by the overlapping edge regions of the side walls of the filling funnel halves, a better sealing is achieved by the sealing strips provided with the steps.
- the filler neck 1 in Figure 1 is provided with a hopper 2, which consists of two mutually movable hopper halves 3, 4. These can be stored and designed in the manner known from EP-OS 82 955.
- FIG. 2 The structure of the suction device itself is shown in Figure 2. From this figure it is clear that the tube 5 is welded to a flange 15, which flange has a bore corresponding to the outer diameter of the tube 5. This flange 15 closes a recess 16 which is provided in a steel plate 17. The bottom of this recess 16 penetrate two through bores 18 which are inserted into pipe sockets 19 which protrude from the plate 17 on the side opposite the pipe 5. On the outstanding ends of the pipe socket 19 support rings 20 are placed, each carrying a plate-shaped suction rubber 21. On the plate 17, a rubber strip 22 corresponding to the plate 17 is glued in its outer dimensions, which has an oval cutout 23, so that the two suction rubbers 21 from the rubber strip are completely surrounded.
- the rubber strip 22 Since the two filling funnel halves 3 and 4 laterally overlap in the open position, a shoulder 24 is formed. So that no good can escape in this area, the rubber strip 22 has a step 25 corresponding to this paragraph 24, so that the bag 14 through the rubber strip 22 density can be pressed.
- the right side of the suction device shown in Figure 2 differs from the left only in that instead of two suction rubbers only a single plate-shaped suction rubber 21 'is used. Instead of a recess 15, the plate 17 'has a bore 26 into which the tube 6 is inserted. Of course, the cutout 23 'is circular according to the use of only one suction rubber 21'.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Befüllen von Säcken mit die zunächst flachen Säcke im Bereich der Seitenkanten ihrer Öffnungsränder haltenden Klemmeinrichtungen, mit an gegenüberliegenden Seiten im Bereich der Öffnungsränder angreifenden und diese aufziehenden Saugern und mit einem Einfüllstutzen.The invention relates to a device for filling sacks with the initially flat sacks in the region of the side edges of their opening edges, with clamping devices which engage on opposite sides in the region of the opening edges and pull them up and with a filler neck.
Bei derartigen, beispielsweise aus der EP-A-82 955, der US-A-38 30 266 sowie der GB-A-691 916 bekannten Vorrichtungen wurde beobachtet, daß an den Innenseiten der Sackwandungen aus thermoplastischem Material in den Bereichen, in denen außen die Sauger angreifen, staubförmige Füllgüter haften bleiben. Dies ist darauf zurückzuführen, daß während des Aufziehens der Sackwandungen die Sauger relativ zu diesen Bewegungen ausführen, so daß dadurch in dem Angriffsbereich der Sauger an den Sackwandungen aus thermoplastischem Material elektrostatische Aufladungen erzeugt werden, die dann staubförmige Füllgüter anziehen. Da die Verschlußschweißnähte üblicherweise später gerade in den Bereichen angebracht werden, an denen die Sauger zuvor die Säcke zum Einfahren des Einfüllstutzens aufgezogen haben, kann das anhaftende staubförmige Füllgut die Qualität der Verschlußschweißnähte beeinträchtigen oder zu undichten Verschweißungen führen.With such devices, for example known from EP-A-82 955, US-A-38 30 266 and GB-A-691 916, it was observed that on the inside of the bag walls made of thermoplastic material in the areas in which the outside attack the suction cups, dust-like contents stick. This is due to the fact that during the opening of the sack walls the suction cups perform relative to these movements, so that in the area of attack the suction cups are generated on the sack walls from thermoplastic material, which then attract dust-like filling goods. Since the sealing seams are usually made later in the areas where the suction cups have previously opened the bags to retract the filler neck, the adhering dusty filling material can impair the quality of the sealing seams or lead to leaky welds.
Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, bei der ein Anhaften von staubförmigem Füllgut an den Sackwandungen im Bereich des Angriffs der Sauger vermieden wird.The object of the invention is therefore to provide a device of the type specified at the outset in which the adherence of dust-like filling material to the sack walls in the region of the attack of the suction devices is avoided.
Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß mindestens unterhalb des oder der Sauger eiier jeden Seite an den Saugerträgern je eine quer verlaufende Leiste aus elastomerem Material vorgesehen ist, die die aufgezogenen Randbereiche der Säcke dichtend gegen die Seitenwände des Fülltrichters andrückt. Bei der erfindungsgemäßen Vorrichtung wird somit den Saugerträgern eine doppelte Funktion zugewiesen, nämlich einmal die des Tragens und Bewegens der Sauger und zum anderen die des Trägers für quer verlaufende dichtende Leisten. Dabei werden die mit den dichtenden Leisten versehenen Saugerträger durch ihre Antriebe nach dem Aufziehen der Sackränder durch die Sauger so gesteuert und bewegt, daß die dichtenden Leisten nach dem Einfahren des Einfüllstutzens gegen dessen Wandungen angedrückt werden. Die Dichtleisten schützen somit die Innenwandungen in dem Bereich, an dem außen die Sauger angreifen oder angegriffen haben, vor aufsteigenden staubförmigem Füllgut, so daß sich dieses nicht an die durch den Aufzugsvorgang elektrostatisch aufgeladenen Bereiche der Sackwandungen anlagern kann.According to the invention, this object is achieved in a device of the generic type in that at least underneath the suction device or the eggs on each side of the suction device carriers there is a transverse strip made of elastomeric material, which presses the opened edge regions of the bags sealingly against the side walls of the filling funnel . In the device according to the invention, the suction cup carriers are thus assigned a double function, namely that of carrying and moving the suction cups and, on the other hand, that of the carrier for transverse sealing strips. The suction cups provided with the sealing strips are controlled and moved by their drives after the sack edges have been opened by the suction cups in such a way that the sealing strips are pressed against the walls of the filler neck after it has been retracted. The sealing strips thus protect the inner walls in the area on which the suction cups have attacked or have been attacked from rising dust-like filling material, so that this cannot accumulate on the areas of the bag walls which are electrostatically charged by the elevator process.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die dichtenden Leisten breiter ausgebildet sind als die Sauger und die Sauger in einer Ausnehmung der Leisten angeordnet sind. Bei dieser Ausgestaltung faßt die Dichtleiste die Sauger vollständig ein, so daß die Bereiche der Sackwandung, an denen die Sauger angreifen oder angegriffen haben, dichtend gegen die Wandungen des Fülltrichters angedrückt werden können und dadurch gegen den Zutritt aufsteigenden staubförmigen Füllguts auch dann geschützt sind, wenn die dichtenden Leisten mit den übrigen Teilen des Einfülltrichters keine vollständige Abdichtung der Einfüllöffnung des Sackes bewirken sollten.In a further embodiment of the invention it is provided that the sealing strips are wider than the suction cups and the suction cups are arranged in a recess in the strips. In this embodiment, the sealing strip completely surrounds the suction cups, so that the areas of the bag wall, on which the suction cups have or have attacked, can be pressed against the walls of the filling funnel and thus also protected against the entry of dusty filling material ascending are when the sealing strips with the remaining parts of the hopper should not completely seal the filling opening of the sack.
Nach einer erfinderischen Weiterentwicklung ist bei Füllstutzen der beispielsweise aus der EP-OS 82 955 bekannten Art mit um zueinander parallele und quer zu der die Klemmeinrichtungen verbindenden Linie angeordnete Achsen gegensinnig verschwenkbaren Fülltrichterhälften, von denen jede Fülltrichterhälfte einen U-förmigen Querschnitt aufweist und deren durch die U-Schenkel gebildeten und zu deren Schwenkebene parallelen Seitenwände in deren ausgeschwenkten Stellung einander überlappen, erfindungsgemäß vorgesehen, daß die Leisten im Bereich der Kanten der überlappenden Seitenwände der Fülltrichterhälften derart mit Stufen versehen sind, daß die aufgezogenen Randbereiche der Säcke durch die Leisten dicht an die einander überlappenden Seitenwände der Fülltrichterhälften andrückbar sind. Grundsätzlich läßt sich zwar bei der aus der EP-A-0 82 955 bekannten Vorrichtung der Fülltrichter aufgrund der ausschwenkbaren Fülltrichterhälften dicht an den Öffnungsrand der zu befüllenden Säcke anschließen. Zwischen den einander überlappenden Randbereichend der Seitenwände der Fülltrichterhälften kann sich aber noch immer ein Spalt ausbilden, durch den staubförmiges Füllgut austreten und sich an die durch die Saugerbewegungen statisch aufgeladenen Bereiche der Sackwandung anlagern kann. Sollten die dichtenden Leisten keine ausreichende Elastizität und Nachgiebigkeit besitzen, um die durch die überlappenden Randbereiche der Seitenwände der Fülltrichterhälften gebildeten Stufen zu überbrücken, wird durch die mit den Stufen versehenen Dichtleisten eine bessere Abdichtung erreicht.According to an inventive further development, filling funnels of the type known, for example, from EP-OS 82 955, with filling funnel halves which can be pivoted in opposite directions about axes parallel to one another and transversely to the line connecting the clamping devices, of which each filling funnel half has a U-shaped cross-section and which through which U-legs formed and parallel to their swivel plane side walls overlap each other in their swung-out position, provided according to the invention that the strips in the area of the edges of the overlapping side walls of the filling funnel halves are provided with steps such that the drawn-up edge regions of the bags through the strips close to the overlapping side walls of the hopper halves can be pressed. Basically, in the device known from EP-A-0 82 955, the filling funnel can be connected closely to the opening edge of the sacks to be filled due to the pivoting-out filling funnel halves. However, a gap can still form between the overlapping edge regions of the side walls of the filling funnel halves, emerge through the dust-like filling material and can accumulate on the areas of the bag wall which are statically charged by the suction movements. If the sealing strips do not have sufficient elasticity and resilience to bridge the steps formed by the overlapping edge regions of the side walls of the filling funnel halves, a better sealing is achieved by the sealing strips provided with the steps.
Auch bei dieser Ausgestaltung sind die Sauger an dem mit den Dichtleisten versehenen Träger oberhalb der Dichtleisten angeordnet oder sie sind in Ausnehmungen der Dichtleisten eingebettet. Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigt

Der Füllstutzen 1 in Fig.1 ist mit einem Fülltrichter 2 versehen, der aus zwei gegeneinander beweglichen Fülltrichterhälften 3,4 besteht. Diese können in der Weise gelagert und ausgestaltet sein, wie sie aus der EP-OS 82 955 bekannt sind.The
Der Aufbau der Sauger selbst ist in Figur 2 dargestellt. Aus dieser Figur wird deutlich, daß das Rohr 5 mit einem Flansch 15 verschweißt ist, wobei dieser Flansch eine dem Außendurchmesser des Rohres 5 entsprechende Bohrung aufweist. Dieser Flansch 15 verschließt eine Ausnehmung 16, die in einer Stahlplatte 17 vorgesehen ist. Den Boden diser Ausnehmung 16 durchsetzen zwei Durchgangsbohrungen 18, die in Rohrstutzen 19 eingesetzt sind, welche auf der dem Rohr 5 gegenüberliegenden Seite der Platte 17 aus dieser hervorragen. Auf die hervorragenden Enden der Rohrstutzen 19 sind Tragringe 20 aufgesetzt, welche je ein tellerförmiges Sauggummi 21 tragen. Auf die Platte 17 ist eine der Platte 17 in ihren äußeren Abmessungen entsprechende Gummileiste 22 aufgeklebt, die einen ovalen Ausschnitt 23 aufweist, so daß die beiden Sauggummis 21 von der Gummileiste vollständig umgeben sind. Da sich die beiden Fülltrichterhälften 3 und 4 in geöffneter Stelle seitlich überlappen, entsteht ein Absatz 24. Damit in diesem Bereich kein Gut austreten kann, weist die Gummileiste 22 entsprechend diesem Absatz 24 eine Stufe 25 auf, so daß der Sack 14 durch die Gummileiste 22 dichten angepreßt werden kann.The structure of the suction device itself is shown in Figure 2. From this figure it is clear that the
Die rechte Seite der in Figur 2 dargestellten Saugeinrichtung unterscheidet sich von der linken nur dadurch, daß statt zwei Sauggummis nur ein einziges tellerförmiges Sauggummi 21′ verwendet wird. Statt einer Ausnehmung 15 weist dabei die Platte 17′ eine Bohrung 26 auf, in die das Rohr 6 eingesetzt ist. Selbstverständlich ist der Ausschnitt 23′ entsprechend der Verwendung nur eines Sauggummis 21′ kreisrund ausgebildet.The right side of the suction device shown in Figure 2 differs from the left only in that instead of two suction rubbers only a single plate-shaped suction rubber 21 'is used.
