In order to guarantee a simple construction of such a device, it is envisaged that the removing device (12) has arranged after it a stop (22) which can be brought into contact with at least one longitudinal side of a bag (2) and is movable transversely to the direction of transport of the bags (2) and which interacts with a further stop (22) which runs parallel to the direction of transport of the bag and against which the bag (2) can be brought into contact. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Entnahme von Säcken und dergleichen aus einem Magazin und Zufuhr zu einer Verarbeitungsposition, z.B. einer Position von der aus die Säcke von einer Fülleinrichtung erfaßbar sind, bei der eine Entnahmeeinrichtung für die Säcke und eine dieser zuge­ordnete Transporteinrichtung zur Beförderung der aus dem Maga­zin gehobenen Säcke zu der vorgegebenen Position, bei der das Magazin eine die Breite eines Sackes erheblich übersteigende Breite aufweist und zur Aufnahme eines Stapels von in Quer­richtung gegeneinander versetzter Säcke bestimmt ist.The invention relates to a device for removing sacks and the like from a magazine and feeding them to a processing position, e.g. a position from which the bags can be detected by a filling device, in which a removal device for the bags and a transport device associated therewith for transporting the bags lifted out of the magazine to the predetermined position, in which the magazine has a width which considerably exceeds the width of a bag has and is intended for receiving a stack of bags offset in the transverse direction.

Bei bekannten Einrichtungen ist meist ein Magazin vorgesehen, dessen Breite jener der Säcke im wesentlichen entspricht in denen die Säcke Kante auf Kante gestapelt eingeschlichtet sind. Bei diesen Einrichtungen erfolgt der Transport der aus dem Magazin entnommenen Sacke im wesentlichen geradlinig zu der vorgesehen Verarbeitungs- oder Übergabeposition, wobei, da auf die Säcke praktisch keine Seitenkräfte einwirken, auf eine seitliche Führung der Säcke verzichtet wird.In known devices, a magazine is usually provided, the width of which essentially corresponds to that of the sacks in which the sacks are stacked edge-to-edge. With these devices, the transport of the sack removed from the magazine takes place essentially in a straight line to the intended processing or transfer position, since since the sacks have practically no lateral forces, the sacks are not guided laterally.

Der Nachteil dieser Lösungen besteht im wesentlichen darin, daß, insbesondere bei Säcken deren Seitenwände mit einer Falte versehen sind, der im Magazin befindliche Stapel von leeren Säcken an seinen Seitenrändern wesentlich höher ist als in seinem Mittelbereich. Diese führt aber nicht nur zu einer Ver­schwendung von Magazinraum sonderen auch zu Problemen bei der Handhabung der gestapelten Säcke und bei der Entnahme der Säcke aus dem Magazin.The disadvantage of these solutions consists essentially in the fact that, particularly in the case of sacks whose side walls are provided with a fold, the stack of empty sacks located in the magazine is considerably higher on its side edges than in its central region. However, this not only leads to a waste of magazine space, but also to problems when handling the stacked bags and when removing the bags from the magazine.

Weiters wurde durch die DE-AS 25 49 264 eine Einrichtung der eingangs erwähnten Art bekannt, bei der das Magazin eine die Breite der Säcke übersteigende Breite aufweist, wobei vorge­sehen ist, die Pakete von Säcken gegeneinander versetzt im Ma­gazin zu stapeln. Die Entnahme der einzelnen Säcke erfolgt bei dieser bekannten Einrichtung mittels Saughebern, die einen mit einer Saugleitung oder Atmosphäre verbindbaren Saugkopf auf­weisen, der den obersten Sack ansaugt um diesen aufgrund einer entsprechenden Druckdifferenz zu halten, wobei die Saugheber aus einer horizontalen Ebene in eine vertikale Ebene ver­schwenkbar sind, aus welcher Stellung die einzelnen Säcke mit­tels eines weiteren Förderers in eine Endstellung gebracht werden, von der aus sie zu einer Füllstation überführbar sind.Furthermore, from DE-AS 25 49 264 a device of the type mentioned was known, in which the magazine has a width exceeding the width of the sacks, it being provided that the packages of sacks are stacked offset in the magazine. The individual bags are removed from this known device by means of suction lifters, which have a suction head which can be connected to a suction line or atmosphere and which sucks the top sack in order to hold it due to a corresponding pressure difference, the suction lifters being pivotable from a horizontal plane into a vertical plane, from which position the individual Bags are brought into an end position by means of a further conveyor, from which they can be transferred to a filling station.

Der Nachteil dieser bekannten Einrichtung liegt in deren kom­pliziertem Aufbau.The disadvantage of this known device is its complicated structure.

Ziel der Erfindung ist es eine Einrichtung der eingangs er­wähnten Art vorzuschlagen, bei der diese Nachteile vermieden sind und die sich durch einen einfachen Aufbau und einen ein­fachen Betriebsablauf auszeichnet.The aim of the invention is to propose a device of the type mentioned at the outset in which these disadvantages are avoided and which is distinguished by a simple structure and a simple operating sequence.

Erfindungsgemäß wird dies dadurch erreicht, daß der Ent­nahmeeinrichtung ein an mindestens einer Längsseite eines Sackes zur Anlage bringbarer und quer zur Transportrichtung der Säcke beweglicher Anschlag nachgeordnet ist, der mit einem parallel zur Tansportrichtung des Sackes verlaufenden wei­teren, gegebenenfalls durch zwei in Transportrichtung der Säcke voneinander distanzierten Fingern gebildeten Anschlag zusammenwirkt, an den der Sack zur Anlage bringbar ist.According to the invention, this is achieved in that the removal device is followed by a stop which can be brought into abutment on at least one longitudinal side of a sack and is movable transversely to the direction of transport of the sack, and which has a further stop running parallel to the direction of transport of the sack, optionally separated by two in the direction of transport of the sack Interacts fingers formed stop against which the sack can be brought to rest.

Durch diese Maßnahmen ist es auf sehr einfache Weise möglich die gegeneinander versetzt gestapelten Säcke in eine Lage zu bringen, von der aus sie auf einfache Weise zu einer Füllsta­tion weitertransportiert werden können. Praktisch ändert sich trotz des breiteren Magazins im Hinblick auf die vorgebene Verarbeitungs- oder Übergabeposition nichts, da es mit dem be­weglichen Anschlag möglich ist, jeden Sack in die gleiche Position in Bezug auf einen seitlichen Abstand von einem vor­gegebenen ortsfesten Punkt zu bringen.These measures make it possible in a very simple manner to bring the sacks which are stacked offset from one another into a position from which they can be easily transported on to a filling station. In practice, despite the wider magazine, nothing changes with regard to the specified processing or transfer position, since it is possible with the movable stop to bring each sack into the same position with respect to a lateral distance from a predetermined fixed point.

Außerdem ist es auch möglich bestehende Einrichtungen für in ihrer Breite den aufzunehmenden Säcken entsprechenden Magazi­nen, bei denen die Säcke aus dem Magazin angehoben und zu einem Übergabetisch gebracht werden möglich, diese gemäß der Erfindung umzurüsten, wobei es lediglich erforderlich ist ent­ sprechend breitere Magazine einzusetzen und den Übergabetisch mit den antsprechenden Anschlägen zu versehen.In addition, it is also possible for existing facilities for magazines corresponding in width to the sacks to be picked up, in which the sacks are lifted out of the magazine and brought to a transfer table, to convert them in accordance with the invention, it being only necessary ent use wider magazines and to provide the transfer table with the appropriate stops.

Nach einem weiteren Merkmal der Erfindung kann vorgesehen sein, daß beide Anschläge quer zur Förderrichtung des Sackes bewegbar gehalten sind.According to a further feature of the invention, it can be provided that both stops are movably held transversely to the conveying direction of the sack.

Auf diese Weise ist es möglich den seitlichen Verschiebeweg für die einzelnen Säcke klein zu halten und in jedem Falle auszurichten.In this way it is possible to keep the lateral displacement for the individual bags small and to align them in any case.

Dabei kann weiters vorgesehen sein, daß die beiden Anschläge gegenläufig zueinander bewegbar und von einem gemeinsamen An­trieb her angetrieben sind. Dies ermöglicht ein besonders exaktes Ausrichten der Säcke.It can further be provided that the two stops can be moved in opposite directions to one another and are driven by a common drive. This enables the bags to be aligned particularly precisely.

Bei einer bevorzugten Ausführungsform der Erfindung kann vor­gesehen sein, daß die Anschläge durch je zwei Paare von Fin­gern gebildet sind die Schlitze der Unterstützung der Säcke von unten her durchsetzten und die schwenkbar gehalten und über exzentrisch an einer antreibbaren Exzenterscheibe an­gelenkte Stangen mit dieser verbunden sind.In a preferred embodiment of the invention it can be provided that the stops are formed by two pairs of fingers, the slots of the support of the sacks penetrate from below and are held pivotably and are connected to this by rods eccentrically connected to a drivable eccentric disc.

Auf diese Weise ergibt sich ein in konstruktiver Hinsicht sehr einfacher Aufbau der Einrichtung.In this way, the construction of the device is very simple in terms of construction.

Um die Einrichtung auf einfache Weise auf verschiedenen Sack­breiten einstellen zu können, kann weiters vorgesehen sein, daß die Finger im wesentlichen L-förmig gebogen sind und mit deren einen Schenkel verstell- und feststellbar in einem schwenkbar angeordneten Arm gehalten sind, der mit der Exzen­terscheibe über eine angelenkte Stange verbunden ist.In order to be able to adjust the device in a simple manner to different sack widths, it can further be provided that the fingers are bent essentially L-shaped and with one leg are held in an adjustable and lockable manner in a pivotably arranged arm which is connected to the eccentric disk a hinged rod is connected.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 eine schematische Seitenansicht im Schnitt gemäß der Linie I-I in der Fig. 2 einer erfindungsgemäßen Einrichtung,
  • Fig. 2 eine Draufsicht auf die erfindungsgemäße Einrichtung und
  • Fig. 3 einen Schnitt entlang der Linie III-III in der Fig. 2.
The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 is a schematic side view in section along the line II in Fig. 2 of a device according to the invention,
  • Fig. 2 is a plan view of the device according to the invention and
  • 3 shows a section along the line III-III in FIG. 2nd

In dem Magazin 1 sind die Säcke 2 gestapelt, wobei die einzel­nen Säcke 2 oder kleinere Pakete von Säcken seitlich versetzt angeordnet sind, wie dies aus der Fig. 2 zu ersehen ist, in der die eingedrückten Falten 3 der Seitenwände der Säcke 2 mit kurz strichlierten Linien und die Seitenkanten 4 der versetzt liegenden Säcke mit lang strichlierten Linien angedeutet sind.In the magazine 1, the bags 2 are stacked, the individual bags 2 or smaller packages of bags being arranged laterally offset, as can be seen from FIG. 2, in which the pressed-in folds 3 of the side walls of the bags 2 are shown with a short dash Lines and the side edges 4 of the offset sacks are indicated with long dashed lines.

Der Stapel der Sacke 2 ist mittels des heb- und senkbaren Bo­dens 5 stets in einer Lage haltbar, in der sich der oberste Sack 2 in einer Lage nahe dem oberen Ende des Magazins 1 be­findet.The stack of sack 2 can always be held in a position by means of the bottom 5 which can be raised and lowered, in which the top sack 2 is located in a position near the upper end of the magazine 1.

Um das Magazin läuft ein Kettenrost 6 über Umlenkräder 11 um, von denen eines, bzw. ein Paar angetrieben ist. Dieser Ketten­rost 6 dient zum Transport der Säcke 2 in Richtung der vorge­gebenen Übergabeposition 7 und ist mit Rostfeldern 8, in denen die beiden Ketten mit Roststäben 10 verbunden sind, versehen die voneinander durch Abschnitte 9, in denen keine Rost­stäbe 10 angeordnet sind, getrennt sind. Dabei sind diese Ab­schnitte 9 zweckmäßigerweise länger als das Magazin in Trans­portrichtung des Kettenrostes 6 bemessen.A chain grate 6 runs around the magazine via deflection wheels 11, one or a pair of which is driven. This chain grate 6 serves to transport the bags 2 in the direction of the predetermined transfer position 7 and is provided with grate fields 8, in which the two chains are connected with grate bars 10, which are separated from one another by sections 9, in which no grate bars 10 are arranged. These sections 9 are expediently dimensioned longer than the magazine in the transport direction of the chain grate 6.

Oberhalb des Magazins ist eine Entnahmeeinrichtung 12 angeord­net, die im wesentlichen durch einen mittels einer Zylinder-­Kolbeneinrichtung bewegbaren Winkelhebel gebildet ist, der an seinem freien Ende einen Saugkopf 13 trägt. Dabei erfolgt die Steuerung der Entnahmeinrichtung 12 in der Weise, daß der Win­kelhebel mit seinem Saugkopf 13 durch den Kettenrost 6 hin­durch greift, während ein Abschnitt 9 ohne Roststäbe unterhalb der Entnahmeeinrichtung 12 vorbeiläuft.A removal device 12 is arranged above the magazine and is essentially formed by an angle lever which can be moved by means of a cylinder-piston device and which carries a suction head 13 at its free end. The removal device 12 is controlled in such a way that the angle lever engages with its suction head 13 through the chain grate 6, while a section 9 passes underneath the removal device 12 without grate bars.

Mit diesem Saugkopf 13 kann der oberste Sack 2 des Magazins 1 angehoben und mit seinem einen Ende in eine oberhalb des Ket­tenrostes 6 liegende Position gebracht werden.With this suction head 13, the top sack 2 of the magazine 1 can be raised and brought with its one end into a position above the chain grate 6.

Das nachfolgende Rostfeld 8 hebt, wie aus der Fig. 1 zu er­sehen ist, den an seinem einen Ende angehobenen Sack 2 über dessen gesamte Länge an, wonach der Saugkopf 13 entspannt wird, sodaß das Ende des Sackes 2 auf den Kettenrost fällt und von diesem mitgenommen wird.The subsequent grate field 8 lifts, as can be seen from FIG. 1, the sack 2 raised at its one end over its entire length, after which the suction head 13 is relaxed, so that the end of the sack 2 falls onto the chain grate and from it is taken away.

Der Kettenrost 6 schiebt den Sack 2 zu einer weiteren Trans­porteinrichtung 14, die im wesentlichen durch mehrere um­ laufende Riemen 15 gebildet ist, deren eine Trume knapp ober­halb eines Tisches 16 verlaufen. Der Antrieb dieser Riemen 15 erfolgt intermittierend durch einen gesteuerten Antrieb 17 der von einem Lagensensor 18 gesteuert ist. Dabei ist vorgesehen, daß der Antrieb nach einer vorbestimmten Verzögerungskurve stillgesetzt wird, sobald der Lagensensor 18 die Vorderkante eines Sackes 2 erfaßt und der wieder aktiviert wird, sobald der Lagensensor, der z.B. als Lichtschranke ausgebildet sein. kann, erfaßt hat, daß die Hinterkante des Sackes über diesen Bereich hinweggegangen ist.The chain grate 6 pushes the sack 2 to a further transport device 14, which is essentially by several running belt 15 is formed, one of which runs just above a table 16. These belts 15 are driven intermittently by a controlled drive 17 which is controlled by a position sensor 18. It is provided that the drive is stopped after a predetermined deceleration curve as soon as the position sensor 18 detects the front edge of a sack 2 and is activated again as soon as the position sensor, which is designed, for example, as a light barrier. can, has detected that the rear edge of the sack has passed over this area.

Auf diese Weise ist sichergestellt, daß der Sack 2 an einer bestimmten Stelle 7 zu liegen kommt, an der er von der Zuführ­einrichtung 19 z.B. einem verschließbaren Fülltrichter 20 er­faßt werden kann.In this way it is ensured that the sack 2 comes to rest at a certain point 7, at which it is e.g. a closable hopper 20 can be detected.

Bei dem dargestellten Ausführungsbeispiel sind in dem Tisch 16 vier quer zur Transportrichtung der Säcke verlaufende Schlitze 21 angeordnet, die von zwei Paaren von Anschlägen 22, 22′ durchsetzt sind.In the illustrated embodiment, four slots 21 are arranged in the table 16 transversely to the transport direction of the bags, which are penetrated by two pairs of stops 22, 22 '.

Diese Anschläge sind, wie sich aus der Fig. 3 ergibt gegenläu­fig zueinander bewegbar. Dabei sind schwenkbar gehaltene Arme 23, 23′ vorgesehen, an deren freien Enden im wesentlichen L-förmig gebogene Finger 24, 24′ verstell- und feststellbar gehalten sind. Dies ermöglicht eine Einstellung des zwischen den Anschlägen 22, 22′, bei deren größter Annäherung verblei­benden Abstandes und damit eine Einstellung auf die Breite der zusammengefalteten Säcken.As can be seen from FIG. 3, these stops are movable in opposite directions to one another. In this case, pivotally held arms 23, 23 'are provided, at the free ends of which fingers 24, 24' which are essentially L-shaped are held so that they can be adjusted and locked. This enables an adjustment of the distance between the stops 22, 22 ', at their greatest approximation remaining distance and thus an adjustment to the width of the folded bags.

Die Arme 23, 23′ sind über Stangen 25 gelenkig mit einer Ex­zenterscheibe 26, die in wechselnden Richtungen um einen be­stimmten Winkelbetrag verschwenkbar ist, verbunden, wobei die Anlenkpunkte der Stangen 25 um 180° gegeneinander versetzt sind.The arms 23, 23 'are articulated on rods 25 with an eccentric disc 26, which can be pivoted in alternating directions by a certain angular amount, the articulation points of the rods 25 being offset from one another by 180 °.

Gelangt nun ein Sack 2 vom Kettenrost 6 mit seiner Vorderkante in den Bereich der Transporteinrichtung 14, so wird er von dieser weiterbefördert und wird durch die Führungsbleche 27 allenfalls vorgerichtet. Dabei befinden sich die Anschläge 22, 22′ in deren äußersten Lage, sodaß der Sack ungehindert nach vorne in Richtung zur Position 7 hin bewegt werden kann.If a sack 2 now comes from the chain grate 6 with its front edge into the region of the transport device 14, it is conveyed further by this and is at most prepared by the guide plates 27. The stops 22, 22 'are in their outermost position, so that the sack can be moved freely in the direction of position 7.

Gelangt der Sack 2 in den Bereich des Lagensensors 18, so wird der Antrieb der Riemen 15 stillgesetzt und der Sack kommt in der Position 7 zum Stillstand, wonach die Exzenterscheibe 26 verschwenkt und dadurch die Anschläge 22, 22′ gegeneinander bewegt werden und der Sack auf diese Weise in eine Mittelposi­tion gebracht wird, aus der er von der Zuführeinrichtung 19 des verschließbaren Fülltrichters 20 ordnungsgemäß erfaßt werden kann.If the sack 2 gets into the area of the position sensor 18, the drive of the belt 15 is stopped and the sack comes to a standstill in position 7, after which the eccentric disk 26 is pivoted and the stops 22, 22 'are moved towards one another and the sack is opened is brought into a central position from which it can be properly gripped by the feed device 19 of the closable hopper 20.
