Description

Die Erfindung betrifft eine Vorrichtung zum Stapeln und Verpacken von flachen Gegenständen, insbesondere von Flachbeutelpackungen, in einen Sammelbehälter der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a device for stacking and packaging flat objects, in particular flat bag packs, in a collecting container of the type specified in the preamble of claim 1.

Es ist eine Vorrichtung dieser Art bekannt (DE-OS 1 786 161), bei der die Zuführeinrichtung im Bereich einer Umlenkstrecke mit waagerechter Achse, in der benachbarte Wände der Zellen radial zur Achse liegen, derart mündet, daß die zugeführten Gegenstände in einer sich radial zur Achse nach außen weitenden Zelle gestapelt und beim Überführen in die waagerecht angeordnete gerade Förderstrecke aufgerichtet werden. Bei Beuteln mit fließfähiger füllung tritt beim Aufrichten innerhalb des Beutels durch Absetzen der Füllung eine Volumenverlagerung und dadurch im unteren Bereich eine Packungsverbreiterung auf. Dies führt dazu, daß zum Verpakken dieser Beutel mehr Volumen und damit auch mehr Verpackungsmaterial benötigt wird, als wenn die Beutel eine gleichmäßige Dicke aufweisen würden. Ein weiterer Nachteil der bekannten Vorrichtung besteht darin, daß die Pakkung mit ihrem gesamten Gewicht auf ihrer meist biegeweichen Unterkante aufstehen, so daß sich in diesem Bereich eine Verstauchung der Kante ergibt, die einmal ein unschönes Aussehen und zum anderen eine zusätzliche Vergrößerung des Packungsvolumens zur Folge haben kann. Hinzu kommt, daß der Ausschieber der bekannten Vorrichtung nur im oberen Bereich einen durchgehenden Steg aufweist, der bezüglich der beim Ausschieben an den Packungen angreifenden Kräfte außermittig angeordnet ist. Dadurch kann sich ein Moment ergeben, das die Packungen einseitig anheben kann, wodurch die Gefahr entsteht, daß die außenliegenden Pakkungen sich zwischen den Vorsprüngen des Schiebers und den benachbarten Zellenwänden verklemmen. Der zum Sammelbehälter führende Austrittskanal besteht dort aus zwei schräg zusammenlaufenden Einführblechen, die zwar eine gewisse Verdichtung der aus den Zellen herausgeschobenen Packungen auf das Verpackungsmaß hervorrufen, ohne die genannten Volumenverlagerungen jedoch rückgängig machen zu können.A device of this type is known (DE-OS 1 786 161), in which the feed device opens out in the region of a deflection section with a horizontal axis, in which adjacent walls of the cells lie radially to the axis, in such a way that the objects fed in a radially stacked towards the axis of the cell widening outwards and erected when being transferred into the horizontally arranged straight conveyor line. In the case of bags with a flowable filling, when the bag is erected, the volume is shifted when the filling is set down, thus widening the pack in the lower area. This means that more volume and thus more packaging material is required for packaging these bags than if the bags had a uniform thickness. Another disadvantage of the known device is that the package with its entire weight stand on its usually flexible lower edge, so that there is a sprain in this area, which results in an unattractive appearance and an additional increase in the package volume may have. In addition, the push-out device of the known device has a continuous web only in the upper region, which is arranged off-center with respect to the forces acting on the packs when pushing out. This can result in a moment that can lift the packs on one side, which creates the risk that the outer packings get stuck between the projections of the slide and the adjacent cell walls. The outlet channel leading to the collecting container there consists of two inclined entry plates which, although they cause a certain compression of the packs pushed out of the cells to the packaging dimensions, without being able to reverse the volume shifts mentioned.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Verpackungsvorrichtung der im Oberbegriff angegebenen Art zu schaffen, bei der Volumenverlagerungen innerhalb der Einzelpackungen während des Stapel- und Verpackungsvorgangs vermieden werden und damit Verpackungsmaterial eingespart und eine höhere Packungsdichte bei der Sammelverpackung erzielt wird, und bei der außerdem eine Verstauchungsgefahr im Bereich der Packungsunterkanten während des Ausschiebevorgangs vermieden wird.In contrast, the invention has for its object to provide a packaging device of the type specified in the preamble in which volume shifts within the individual packs are avoided during the stacking and packaging process and thus packaging material is saved and a higher packing density is achieved in the bulk packaging, and in addition a risk of spraining in the area of the lower edge of the pack during the pushing-out process is avoided.

Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Further advantageous refinements and developments of the invention result from the subclaims.

Die erfindungsgemäße Lösung geht von dem Gedanken aus, daß die gegebenenfalls zuvor in einer Egalisierungsvorrichtung flachgedrückten Packungen jeweils flachliegend in den Zellen abgelegt, zur Schiebeeinrichtung gefördert und in den Sammelbehälter geschoben werden, um eine möglichst hohe Packungsdichte bei der Sammelverpackung zu erzielen. Dadurch ergeben sich erhebliche Einsparungen sowohl beim Verpackungsmaterial als auch beim Transport-und Lagerraumbedarf.The solution according to the invention is based on the idea that the packs, which may have previously been flattened in a leveling device, are placed flat in the cells, conveyed to the pushing device and pushed into the collecting container in order to achieve the highest possible packing density in the bulk packaging. This results in considerable savings both in the packaging material and in the transport and storage space requirements.

Die Geradförderstrecke der erfindungsgemäßen Fördereinrichtung ist als Vertikalförderstrecke ausgebildet, in der das flachliegende Verpackungsgut schrittweise von einer obenliegenden Eintrittsstelle zu einer untenliegenden Austrittsstelle gefördert wird. Die Vertikalförderstrecke enthält zwei einander mit ihren abstehenden Wänden unter Bildung der Zellenböden ergänzende gegensinnig umlaufende Endlosförderer. Die einzeln ankommenden Packungen werden in die Zellen in einer vorgegebenen Stückzahl eingeführt. Nach Erreichen dieser Stückzahl wird jeweils ein Schrittschaltgetriebe angesteuert, das das Zellensystem um eine Zellenhöhe nach unten bewegt. Die Zählung der einzelnen Packungen erfolgt dabei zweckmäßig automatisch mit Hilfe eines Lichtsensors.The straight conveyor section of the conveyor device according to the invention is designed as a vertical conveyor section, in which the flat-lying packaged goods are conveyed step by step from an overhead entry point to a bottom exit point. The vertical conveyor section contains two endless conveyors which rotate in opposite directions and complement one another with their protruding walls, forming the cell bottoms. The individually arriving packs are introduced into the cells in a predetermined number of pieces. After reaching this number, a stepper transmission is actuated, which moves the cell system down one cell height. The individual packs are expediently counted automatically with the aid of a light sensor.

Die im unteren Bereich auf der Rückseite der Vertikalförderstrecke angeordnete Schiebeeinrichtung wird automatisch vorgeschoben, wenn eine bestimmte Anzahl Zellen gefüllt und in der richtigen Position vor den zugehörigen Schieber gebracht ist. Die Schieberplatte weist zweckmäßig einen zentralen senkrechten Steg und beidseitig symmetrisch überstehende Vorsprungreihen auf, die beim Schiebervorschub kammartig in die benachbarten Zellenteile eingreifen. Die zentrale Anordnung des Stegs gewährleistet. daß keine Momentenkräfte an den Packungen angreifen, die ein Verkanten verursachen könnten. Die Schieberplatte kann dabei eine mehr oder weniger große Anzahl von Zellen erfassen, je nachdem, wie viele Einzelpackungen mit einem Schiebervorschub herausgeschoben werden sollen. Bei kürzeren Schieberplatten befinden sich zwischen der Eingabestelle und den für die Ausgabe vorgesehenen Zellen vorder- und rückseitige Anschläge, die verhindern, daß aus den dazwischenliegenden Zellen Packungen nach vorn oder hinten herausgleiten können.The pusher located in the lower area on the back of the vertical conveyor line is automatically advanced when a certain number of cells are filled and placed in the correct position in front of the associated pusher. The slide plate expediently has a central vertical web and rows of protrusions protruding symmetrically on both sides, which engage like a comb in the adjacent cell parts when the slide is advanced. The central arrangement of the bridge ensures. that no momentary forces act on the packs that could cause them to tilt. The slide plate can capture a more or less large number of cells, depending on how many individual packs are to be pushed out with a slide feed. In the case of shorter slide plates, there are stops on the front and rear sides between the input point and the cells provided for the output, which prevent packs from sliding forward or backward from the cells in between.

Die beiden vorzugsweise als Kettenpaare ausgebildeten Endlosförderer können seitlich relativ zueinander verschoben werden, so daß innerhalb bestimmter Grenzen eine Anpassung auf unterschiedliche Packungsformate möglich ist. Die beiden Kettenpaare können außerdem um eine untenliegende Achse so nach außen geschwenkt werden, daß z. B. im Störungsfall ein einfacher Zugriff zu den einzelnen Zellen möglich ist.The two endless conveyors, which are preferably designed as chain pairs, can be laterally displaced relative to one another, so that adaptation to different pack formats is possible within certain limits. The two pairs of chains can also be pivoted outwards about an underlying axis so that, for. B. easy access to the individual cells is possible in the event of a fault.

Die von den Endlosförderern abstehenden Wände bilden zweckmäßig den einen Schenkel eines Winkelstücks, dessen anderer, dazu senkrechter Schenkel im Bereich der Vertikalförderstrecke nach oben weist und eine seitliche Zellenbegrenzung bildet. Für höhere Packungsstapel können auch abwechselnd je ein Winkelstück und ein Flachstück übereinander angeordnet werden, die insgesamt eine größere Teilung bilden.The walls protruding from the endless conveyors expediently form the one leg of an angle piece, the other leg of which, perpendicular to it, points upward in the region of the vertical conveying path and forms a lateral cell boundary. For higher pack stacks, an angle piece and a flat piece can alternately be arranged one above the other, which form a larger division overall.

Die in der Zeichnung dargestellte Sammelverpackungsmaschine besteht im wesentlichen aus einer aus zwei im Abstand an einem Maschinengestell 10 angeordneten, aus je einem Kettenpaar bestehenden Endlosförderern 12, 14 gebildeten, durch an den Kettenpaaren angelenkte Winkelstücke 16 in einzelne Zellen 18 unterteilten, vertikal verlaufenden geraden Förderstrecke 20, einer von oben in die oberste Zelle der Vertikalförderstrecke einmündenden, das flache Verpackungsgut 22 nacheinander flachliegend in die Zellen 18 ablegenden und zu Gruppen aufeinanderstapelnden Zuführeinrichtung 24 und einer unterhalb der Zuführeinrichtung 24 angeordneten mehrere Zellen 18 überdeckenden Schiebeeinrichtung 26 zum gruppenweisen Ausschieben des Verpackungsguts aus mehreren Zellen über einen Austrittskanal 28 in einen nicht dargestellten Sammelbehälter.The collective packaging machine shown in the drawing essentially consists of a vertically extending straight conveyor line 20, which consists of two endless conveyors 12, 14 arranged at a distance from a machine frame 10, each consisting of a pair of chains, and divided into individual cells 18 by angle pieces 16 hinged to the chain pairs , a from above into the uppermost cell of the vertical conveyor line, the flat packaged goods 22 lying one after the other lying flat in the cells 18 and stacked in groups and a stacking device 24 and a slide device 26 arranged below the feed device 24 and covering several cells 18 for group-wise pushing out of the packaged goods from several cells via an outlet channel 28 into a collecting container, not shown.

Die Winkelstücke 16 sind an den Kettenpaaren 12, 14 in gleichen Abständen voneinander angelenkt und begrenzen im Bereich der Vertikalförderstrecke 20 jeweils paarweise die Zellen 18. Die senkrecht über die Kettenpaare 12, 14 überstehenden Winkelschenkel 30 ergänzen sich dabei jeweils zu einem Zellenboden, während die parallel zum betreffenden Kettentrum 32 nach oben weisenden Schenkel 34 der Winkelstücke eine Seitenbegrenzung der Zellen 18 bilden. Um eine genaue Ausrichtung der Winkelstücke 16 sowohl entlang der Vertikalförderstrecke 20 als auch auf der übrigen Umlaufbahn zu gewährleisten, ist jedes Winkelstück 16 mit einem zur Schwenkachse parallelen Führungszapfen 35 in einer Führungsnut einer nicht dargestellten, maschinengestellfesten Platte geführt. Im Bereich der gerade verlaufenden Bewegungsstrecken verläuft die Führungsnut ebenfalls gerade, während sie im Bereich der oberen und unteren Umlenkung einen vorzugsweise kreisförmig gekrümmten Verlauf aufweist. Im oberen Bereich in der Nähe der Zuführeinrichtung 24 kann jedoch auch ein anders gekrümmter Kurvenverlauf vorgesehen werden, beispielsweise um eine etwas steilere Anstellung der abstehenden Winkelschenkel 30 zu erzielen, damit sie eine größere Beschickungsöffnung freigeben.The angle pieces 16 are articulated on the chain pairs 12, 14 at equal distances from one another and delimit the cells 18 in pairs in the area of the vertical conveyor path 20. The angle legs 30 projecting vertically above the chain pairs 12, 14 complement each other to form a cell floor, while the parallel form a side boundary of the cells 18 with respect to the relevant chain center 32, the leg 34 of the angle pieces pointing upward. In order to ensure a precise alignment of the angle pieces 16 both along the vertical conveying path 20 and on the remaining orbit, each angle piece 16 is guided with a guide pin 35 parallel to the pivot axis in a guide groove of a plate (not shown) fixed to the machine frame. The guide groove also runs straight in the region of the straight movement paths, while it has a preferably circularly curved course in the region of the upper and lower deflection. In the upper area in the vicinity of the feed device 24, however, a differently curved course of the curve can also be provided, for example in order to achieve a somewhat steeper inclination of the protruding angle legs 30 so that they open up a larger loading opening.

Die Zellenbreite kann durch Verstellen des Abstands zwischen den beiden Kettenpaaren 12, 14 dem jeweiligen Verpackungsgut angepaßt werden. Dies erfolgt relativ einfach durch gemeinsames Verschieben der beiden Kettenpaare in entgegengesetzter Richtung mit Hilfe einer Spindelanordnung 36 mit Rechts- und Linksgewinde durch Betätigen des Handrads 38.The cell width can be adapted to the respective packaged goods by adjusting the distance between the two pairs of chains 12, 14. This is done relatively simply by moving the two pairs of chains together in the opposite direction with the aid of a spindle arrangement 36 with right-hand and left-hand threads by actuating the handwheel 38.

Die beiden Kettenpaare sind synchron über einen Schrittmotor 40 und ein Zahnradgetriebe 42 sowie je eine Gelenk- und Teleskopwelle 44, die den Querverschiebungen der Kettenpaare folgen kann, durch Antrieb der unteren Kettenräder 46 so angetrieben, daß sich die Zellen 18 im Bereich der Vertikalförderstrecke 20 von der Eintrittsstelle zur Austrittsstelle schrittweise nach unten bewegen. Der Schrittmotor 40 wird dabei über eine nicht gezeigte Zentralsteuerung nach Maßgabe der Anzahl der von der Zuführeinrichtung 44 in die jeweils oberste Zelle 18 abgelegten Packungen 22 angesteuert. Die auf dem Zuführband ankommenden Einzelpackungen 22 werden über einen Lichtsensor 48 in der Zentralsteuerung gezählt und mit einem individuell für jede Zelle der Vertikalförderstrecke 20 einstellbaren Sollwert verglichen.The two chain pairs are synchronously driven by a stepper motor 40 and a gear wheel 42 and a universal joint and telescopic shaft 44, which can follow the transverse displacements of the chain pairs, by driving the lower chain wheels 46 so that the cells 18 in the area of the vertical conveyor path 20 from gradually move the entry point down to the exit point. The stepper motor 40 is controlled via a central control (not shown) in accordance with the number of packs 22 deposited by the feed device 44 in the uppermost cell 18. The individual packs 22 arriving on the feed belt are counted by a light sensor 48 in the central control and compared with a target value that can be set individually for each cell of the vertical conveyor path 20.

Die Zuführeinrichtung 24 enthält ein umlaufendes Förderband, auf das die Packungen 22 hintereinander entweder von Hand oder automatisch aufgelegt werden. Um das Füllgut innerhalb der Einzelpackungen gleichmäßig zu verteilen, ist über dem Zuführband ein auf die ankommenden Packungen unter Ausübung eines Drucks einwirkendes Egalisierungsband 50 angeordnet.The feed device 24 contains a rotating conveyor belt on which the packs 22 are placed one behind the other either by hand or automatically. In order to distribute the filling material evenly within the individual packs, a leveling belt 50 acting on the incoming packs while exerting pressure is arranged above the feed belt.

Die Schiebeeinrichtung 26 ist stirnseitig mit einer Schieberplatte 52 versehen, die im Falle des in den Fig. 1 bis 4 gezeigten Ausführungsbeispiels einen mittleren, sich über drei Zellen 18 erstreckenden Steg 54 sowie nach beiden Seiten symmetrisch überstehende Vorsprünge 56 aufweist, die beim Ausschiebevorgang kammartig in die benachbarten Zellenteile eingreifen. Das genannte Ausführungsbeispiel, bei dem die Winkelstücke 16 unmittelbar hintereinander an den Kettenpaaren angeordnet sind, ist vor allem für Flachbeutelpackungen, wie Vierseiten-Siegelrandbeutel oder Schlauchbeutel mit relativ geringer Dicke bestimmt.The sliding device 26 is provided on the end face with a slide plate 52 which, in the case of the exemplary embodiment shown in FIGS. 1 to 4, has a central web 54 which extends over three cells 18 and protrusions 56 which protrude symmetrically on both sides and which comb-like in the push-out process intervene in the neighboring cell parts. The exemplary embodiment mentioned, in which the angle pieces 16 are arranged one behind the other on the chain pairs, is primarily intended for flat bag packs, such as four-sided sealed edge bags or tubular bags with a relatively small thickness.

Für etwas dickere Beutel mit sperrigerem Füllgut, wie Bonbonbeutel, werden etwas höhere Zellen 18' benötigt, wie sie beispielsweise in Fig. 5 gezeigt sind. Bei dieser Anordnung befindet sich zwischen jedem Winkelstück 16 noch ein Flachstück 58, das einen Teil der seitlichen Zellenbegrenzung bildet. Diese Unterteilung der Zellenbegrenzung wird gewählt, weil an den gekrümmten Umlenkstellen 60 nur verhältnismäßig kurze Schenkellängen der Winkelstücke 16 zugelassen sind, wenn ein zuverlässiger Betriebsablauf gewährleistet sein soll. Außerdem kann der Zellenvorschub und der Füllvorgang bei einer derart unterteilten Zelle 18' in zwei Taktschritten erfolgen, was gleichfalls zur Erhöhung der Betriebszuverlässigkeit beiträgt.For somewhat thicker bags with bulky contents, such as candy bags, somewhat higher cells 18 'are required, as shown for example in FIG. 5. In this arrangement there is still a flat piece 58 between each angle piece 16, which forms part of the lateral cell boundary. This subdivision of the cell boundary is chosen because at the curved deflection points 60 only proportionately short leg lengths of the elbows 16 are permitted if a reliable operation is to be guaranteed. In addition, the cell feed and the filling process can take place in two clock steps in the case of a cell 18 ′ divided in this way, which likewise contributes to increasing the operational reliability.

Wie ein Vergleich zwischen den Fig. 4 und 5 zeigt, ist die Umrißgestalt der Schieberplatte 52 der gewählten Zellenkonfiguration und -größe angepaßt.As a comparison between FIGS. 4 and 5 shows, the outline shape of the slide plate 52 is adapted to the selected cell configuration and size.

Die von der Schieberplatte 52 nicht erfaßten Zellen 18 der Vertikalförderstrecke 20 werden zweckmäßig mit nicht dargetellten vorder- und rückseitigen Begrenzungsflächen gegen ein versehentliches Herausgleiten der darin befindlichen Packungen geschützt.The cells 18 of the vertical conveying path 20, which are not gripped by the slide plate 52, are expediently protected with front and rear boundary surfaces (not shown) against inadvertent sliding out of the packs therein.

Auf der der Schiebeeinrichtung 26 gegenüberliegenden Seite der Vertikalförderstrecke 20 befindet sich der trichterförmige Austrittskanal 28 mit rechteckigem Querschnitt, an dessen Austrittsöffnung ein Sammelbehälter zur Aufnahme des herausgeschobenen Packungsstapels angelegt werden kann. Der Austrittskanal besteht aus vier Winkelblechen 62,64,66,68, deren Schenkel sich an den jeweiligen Seitenflächen paarweise überlappen und deren Biegekanten 70 die Kanalkanten bilden. Die Winkelbleche 62,64 und 66,68 sind paarweise um gestellseitig angeordnete vertikale Achsen 72 unter Erweiterung der Austrittsöffnung entgegen der Kraft einer Feder 74 gegeneinander verschwenkbar. Zusätzlich sind auch noch die oberen Winkelbleche 62, 66 um eine gemeinsame horizontale Achse gegenüber den unteren Winkelblechen 64, 68 nach oben verschwenkbar. Das Verschwenken der Winkelbleche um die betreffenden Achsen erfolgt dabei unter der Einwirkung der aus den Zellen 18 herausgeschobenen Packungen, die auf diese Weise in ihrer Bewegung gebremst und im Stapel zusammengehalten werden. Die hinter dem herausgeschobenen Stapel wieder in ihre Ausgangsstellung zurückklappenden Winkelbleche verhindern ferner ein Zurückgleiten der Packungen aus dem Sammelbehälter.The funnel-shaped outlet channel 28 with a rectangular cross section is located on the side of the vertical conveyor section 20 opposite the sliding device 26, at the outlet opening of which a collecting container for receiving the pushed-out stack of packs can be placed. The outlet channel consists of four angle plates 62, 64, 66, 68, the legs of which overlap in pairs on the respective side faces and the bending edges 70 of which form the channel edges. The angle plates 62, 64 and 66, 68 can be pivoted in pairs against each other about vertical axes 72 arranged on the frame side, with the outlet opening being widened, against the force of a spring 74. In addition, the upper angle plates 62, 66 can also be pivoted upward about a common horizontal axis relative to the lower angle plates 64, 68. The pivoting of the angle plates about the axes in question takes place under the action of the packs pushed out of the cells 18, which in this way are slowed down in their movement and held together in the stack. The angle plates which fold back into their initial position behind the stack pushed out further prevent the packs from sliding back out of the collecting container.
