Des weiteren betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for the progressively graded grouping of products, such as the stacking of packaged goods units from the bottom up to a packaged goods stack to be fed to a multi-packer, in which the packaged goods units running along a transport path to the end of a grouping station are arranged in rows by processes in the transverse direction with step-like subgroups of packaged goods units are brought together and the subgroups are carried along by one step and then all packaged goods units traveling in the transverse direction are transported together in the longitudinal direction by one step length. Furthermore, the invention relates to a device for performing the method.

In einer bekannten Vorrichtung zum Stapeln von Packguteinheiten in fortschreitenden Stufen von unten nach oben zu einem Packgutstapel, bestehend aus einer bestimmten Anzahl von Gegenständen, die anschlie­ßend in eine Sammelpackmaschine überführt werden, laufen die Packgut­einheiten auf einer Förderstrecke in geschlossenen Reihen gegen ei­ nen Anschlag und werden dann reihenweise von einer Hubeinrichtung un­ter die zu einer Stufenformation gestapelten Teilstapel verbracht und mit diesen gemeinsam angehoben, nachdem zuvor die Teilstapel stützenden Rückhalteelemente aus der Bewegungsbahn der sich aufwärts bewegenden Packguteinheitenreihe gefahren wurden. Nach dem Zusammen­führen der Reihe Packguteinheiten mit den stufenförmig aufgebauten Teilstapeln und Wiederabstützen der gestapelten Packguteinheiten wer­den diese um eine Stufenlänge mittels eines die einzelnen Stufen hin­tergreifenden Stufenschiebers weitergetaktet und letztlich der fer­tiggestellte Packgutstapel am Ende der Stapelreihe von einem Quer­schieber in die Sammelpackmaschine geschoben.In a known device for stacking packaged goods in progressive stages from the bottom up to a pack of packaged goods consisting of a certain number of objects which are then transferred to a multi-packer, the packaged goods run on a conveyor line in closed rows against egg NEN stop and are then brought in rows by a lifting device under the stacked sub-stacks and raised together with these after the sub-stack supporting retaining elements have been moved out of the path of the upward moving packaged goods row. After merging the row of packaged goods units with the step-by-piece partial stacks and re-supporting the stacked packaged goods units, these are clocked by a step length by means of a step shifter that grips behind the individual steps, and finally the finished packaged goods stack is pushed by a cross slide into the multi-packer at the end of the stack row.

Voraussetzung für das fortschreitend stufenförmige Stapeln ist das Vorhandensein der sich aus Teilstapeln zusammensetzenden Stufenforma­tion am Anfang des Stapelvorgangs.A precondition for the progressive step-like stacking is the existence of the step formation composed of partial stacks at the beginning of the stacking process.

Der Aufbau der Stufenformation zu Beginn des Stapelverfahrens sowie der Abbau der Stufenformation, d. h. das Bilden von kompletten Pack­gutstapeln aus den verbleibenden Teilstapeln am Ende des Stapelvor­gangs, erfolgte bisher von Hand.The formation of the step formation at the beginning of the stacking process and the dismantling of the step formation, i. H. The formation of complete stacks of packaged goods from the remaining partial stacks at the end of the stacking process has previously been done by hand.

Hier setzt die Erfindung ein, deren Aufgabe darin besteht, bei einem Verfahren und einer Vorrichtung der genannten Gattung den Aufbau der Stufenformation von Teilgruppen am Anfang des Gruppiervorgangs und den Abbau der Stufenformation am Ende des Gruppiervorgangs zu automa­tisieren.This is where the invention comes in, the object of which is to automate the construction of the step formation of subgroups at the beginning of the grouping process and the dismantling of the step formation at the end of the grouping process in a method and a device of the type mentioned.

Ausgehend von einem Verfahren der eingangs genannten Gattung sieht das Verfahren nach der Erfindung hierzu vor, daß zum automatischen Aufbau der Stufenformation eine einzelne Packguteinheit, dann Reihen aus zwei, drei und mehr Packguteinheiten jeweils nacheinander bis zum Ende der Gruppierstation, vorzugsweise bis zu einem Anschlag, zu­geführt und in Querrichtung verfahren werden, daß zum automatischen Abbau der Stufenformation alle in Querrichtung verfahrenen Packgut­einheiten gemeinsam in Längsrichtung um eine Stufenlänge weitertrans­portiert und jeweils soviele Packguteinheiten bis zum Ende der Grup­pierstation, vorzugsweise bis zum Anschlag, zugeführt und in Quer­richtung verfahren werden wie Teilgruppen vorhanden sind. Dabei kön­nen die Packguteinheiten in Querrichtung von unten nach oben verfah­ren und in der angehobenen Position gehalten werden.Proceeding from a method of the type mentioned at the outset, the method according to the invention provides that for the automatic formation of the step formation a single packaged goods unit, then rows of two, three and more packaged goods units, one after the other, up to the end of the grouping station, preferably up to a stop, fed and moved in the transverse direction that for automatic Dismantling the step formation, all packaged goods moving in the transverse direction are transported together in the longitudinal direction by a step length and as many packaged goods are fed to the end of the grouping station, preferably up to the stop, and moved in the transverse direction as there are subgroups. The packaged goods can be moved in the transverse direction from bottom to top and held in the raised position.

Die Vorrichtung zur Durchführung des Verfahrens geht aus von einer solchen mit einer Transportbahn, auf der die Packguteinheiten zur Bildung von Reihen aus Packguteinheiten in einer Gruppierstation ge­gen einen Anschlag laufen, mit einer die einzelnen Reihen Packgutein­heiten von der Transportbahn in Querrichtung wegführenden und mit stufenförmig aufgebauten Teilgruppen von Packguteinheiten zusammen­führenden Querfördereinrichtung und mit einem die stufenförmig ange­ordneten Packguteinheiten hintergreifenden und diese in Längsrich­tung um eine Stufenlänge weitertransportierenden Stufenschieber und ist gekennzeichnet durch eine der Querfördereinrichtung vorgeordnete Zufuhreinrichtung, die nach einer Programmsteuerung in zeitlicher Ab­stimmung mit der Hubbewegung der Querfördereinrichtung derart im Sin­ne einer Freigabe von Packguteinheiten betätigbar ist, daß zum auto­matischen Aufbau der Stufenformation eine einzelne Packguteinheit, dann Reihen aus zwei, drei und mehr Packguteinheiten jeweils nachein­ander der Gruppierstation zugeführt werden und zum automatischen Ab­bau der Stufenformation jeweils soviele Packguteinheiten zugeführt werden wie Teilgruppen nach dem Weitertransport der Packguteinheiten in Längsrichtung durch den Stufenschieber vorhanden sind.The device for carrying out the method is based on one with a transport path on which the packaged goods units run against a stop to form rows of packaged goods units in a grouping station, with a subgroup leading the individual rows of packaged goods units away from the transport track in the transverse direction and with step-like subgroups of packaging material units bringing together and with a step shifter engaging behind the step-wise arranged packaging material units and transporting them further in the longitudinal direction by a step length and is characterized by a feeding device arranged upstream of the cross conveyor device, which according to a program control in time coordination with the lifting movement of the cross conveyor device in such a way as to release packaging material units it can be actuated that for the automatic build-up of the step formation a single packaged goods unit, then rows of two, three and me HR packaged goods units are fed one after the other to the grouping station and as many packaged goods units are fed for automatic dismantling of the step formation as there are subgroups after the packaged goods units have been transported in the longitudinal direction by the step shifter.

Beim fortschreitend stufenförmigen Stapeln von Packguteinheiten zu Packgutstapeln zum anschließenden Überführen in eine Sammelpackma­schine laufen die einzelnen Packguteinheiten von einer Transportbahn kommend in eine Stapelstation und werden von hier durch reihenweises Anheben mit stufenförmig aufgebauten in einer höheren Ebene gehalte­nen Teilstapeln zusammengeführt, wobei diese gleichzeitig um eine Stufenhöhe mitangehoben werden. Der bei dieser von unten nach oben fortschreitenden Stapelbildung am Ende der Teilstapelreihe fertigge­stellte Packgutstapel sowie alle Teilstapel werden jeweils nach Been­digung des Stapelvorgangs gemeinsam in Längsrichtung mit Hilfe eines hinter die Stufen greifenden Stufenschiebers vorgetaktet. Der Vor­teil dieses stufenförmigen Stapelverfahrens liegt bekanntlich darin, daß die Stapelbildung vom Einlauf der Packguteinheiten bis zum Weg­führen der fertigen Stapel in einem kontinuierlichen Durchlauf bei geringer Taktfolge aller erforderlichen Transportmittel erfolgen kann, was eine schonende Behandlung der Packgüter und eine funktions­sichere Arbeitsweise ermöglicht.In the progressively step-by-step stacking of packaged goods units to packaged goods stacks for subsequent transfer into a multi-packer, the individual packaged goods units come from a transport path into a stacking station and are brought together from here by lifting in rows with step-by-part partial stacks held at a higher level, which are simultaneously lifted by one step height will. The stack of goods to be finished, which progresses from bottom to top at the end of the row of partial stacks, as well as all partial stacks are each pre-timed together in the longitudinal direction after the end of the stacking process with the aid of a step shifter reaching behind the steps. As is well known, the advantage of this step-by-step stacking process is that the stack formation from the infeed of the packaged goods to the removal of the finished stacks can take place in a continuous cycle with a short cycle of all the necessary means of transport, which enables gentle handling of the packaged goods and a functionally reliable method of operation.

Voraussetzung für das fortschreitend stufenförmige Stapeln von in ei­ner Reihe zugeführten Packguteinheiten ist das Vorhandensein einer Stufenformation am Anfang des Stapelvorgangs.A prerequisite for the progressive step-by-step stacking of packaged goods fed in a row is the existence of a step formation at the beginning of the stacking process.

Das automatische Aufbauen dieser Stufenformation, wie es die Erfin­dung vorsieht, wird nachfolgend anhand der Figuren 1 bis 5 beschrie­ben.The automatic construction of this step formation, as provided by the invention, is described below with reference to FIGS. 1 to 5.

Die erfindungsgemäße Vorrichtung setzt sich im wesentlichen zusammen aus einer umlaufend angetriebenen Fördereinrichtung 5, die einer Transportbahn 3 nachgeordnet und zwischen einer unteren Aufnahmestel­lung und oberen Abgabestellung entsprechend der Pfeilrichtung ver­fahrbar ist, aus die Packguteinheiten 1a in einer angehobenen Posi­tion durch seitliches Unterstützen übernehmende Rückhalteflächen 7 (Fig. 12), die in die Vertikalbewegungsbahn der Packguteinheiten 1a und zurückschwenkbar sind, und aus einer vor der Fördereinrichtung 5 installierten Packguteinheitensperre 4, die im Sinne einer Freigabe und Sperrung des Durchlasses von einem programmierbaren Zählwerk aus steuerbar ist.The device according to the invention essentially consists of a revolving driven conveying device 5, which is arranged downstream of a transport path 3 and which can be moved between a lower receiving position and an upper delivery position in the direction of the arrow, from the packaged goods units 1a in a raised position by means of lateral support elements 7 (FIG . 12), which can be pivoted back and forth into the vertical movement path of the packaged goods units 1a, and from a packaged goods unit lock 4 installed in front of the conveying device 5, which can be controlled from a programmable counter in the sense of releasing and blocking the passage.

Die auf der Transportbahn 3 kontinuierlich zugeführten von der Pack­guteinheitensperre 4 freigegebenen Packguteinheiten 1a gelangen auf die Fördereinrichtung 5, werden von dieser aneinanderliegend unter seitlicher Ausrichtung an Leitblechen 10 (Fig. 12) gegen einen end­seitig der Fördereinrichtung 5 positionierten Anschlag 6 transpor­tiert, von der Fördereinrichtung 5, nachdem diese von einer Licht­schrankensteuerung als Kontrolleinrichtung 16 den Befehl zum Anheben erhalten hat, angehoben und von den seitwärts in die Bewegungsbahn der Packguteinheiten 1a schwenkbaren Rückhalteflächen 7 unter seit­licher Ausrichtung an Leitblechen 10a (Fig. 12) übernommen, worauf die Fördereinrichtung 5 in ihre Ausgangsposition zurückkehrt.The packaged goods units 1a released continuously from the packaged goods unit lock 4 on the transport path 3 reach the conveying device 5, are transported by the conveying device 5 lying against one another with lateral alignment on guide plates 10 (FIG. 12) against a stop 6 positioned at the end of the conveying device 5 after it has received the command to lift it from a light barrier control as control device 16, it is lifted and taken over by the retaining surfaces 7 which can be pivoted sideways into the movement path of the packaged goods units 1 a and aligned laterally on guide plates 10 a (FIG. 12), whereupon the conveying device 5 is in its starting position returns.

Dabei wird die Packguteinheitensperre 4 über die Zähleinrichtung der­art betätigt, daß in einem ersten Arbeitsschritt eine Packguteinheit 1a freigegeben wird, gegen den Anschlag 6 läuft, angehoben und in dieser Position von den Rückhalteflächen 7 gehalten wird (Fig. 1 und 2).The packaged goods unit lock 4 is actuated via the counting device in such a way that in a first step a packaged goods unit 1a is released, runs against the stop 6, is lifted and is held in this position by the retaining surfaces 7 (FIGS. 1 and 2).

In einem zweiten Arbeitsschritt werden zwei Packguteinheiten 1a frei­gegeben, gegen den Anschlag 6 transportiert, angehoben und von den Rückhalteflächen 7 gehalten, wobei die in Zulaufrichtung vorn liegen­de Packguteinheit 1a die in der angehobenen Position gehaltene Pack­guteinheit mitanhebt (Fig. 2 und 3).In a second step, two packaged goods units 1a are released, transported against the stop 6, raised and held by the retaining surfaces 7, the packaged goods unit 1a lying in the feed direction also lifting the packaged goods unit held in the raised position (FIGS. 2 and 3).

In einem dritten Arbeitsschritt werden drei Packguteinheiten 1a frei­gegeben und gegen den Anschlag 6 transportiert, angehoben und in Po­sition gehalten, wobei die beiden in Zulaufrichtung vorn liegenden Packguteinheiten 1a die in der angehobenen Position gehaltenen Pack­guteinheiten mitanheben (Fig. 3 und 4). Hiermit ist die Vorausset­zung für den sich anschließenden fortschreitend stufenförmigen Sta­pelvorgang von Packguteinheiten 1a geschaffen.In a third step, three packaged goods units 1a are released and transported against the stop 6, lifted and held in position, the two packaged goods units 1a lying in the feed direction also lifting the packaged goods units held in the raised position (FIGS. 3 and 4). This creates the prerequisite for the subsequent progressively step-by-step stacking process of packaged goods units 1a.

In dem folgenden Arbeitsschritt gelangt dann eine vollständige Reihe aus vier Packguteinheiten 1a nach Freigabe durch die Sperre 4 gegen den Anschlag 6, wird angehoben mit den Teilstapeln unter Mitnahme derselben zusammengeführt und in Position gehalten (Fig. 4 und 5).In the following work step, a complete row of four packaged goods units 1 a comes after release by the lock 4 against the stop 6, is raised and brought together with the partial stacks, and held in position (FIGS. 4 and 5).

Figur 5 zeigt einen fertiggestellten Packgutstapel 1, der gemäß Pfeilrichtung mittels eines in Längsrichtung vor und zurück verfahr­baren Stufenschiebers 8 in eine nachfolgende strichpunktiert gezeich­nete Position auf einen Ausfuhrtisch 9 verbracht wird, wozu sich Mit­nehmer 8a-8d des Stufenschiebers 8 hinter die jeweilige Stapelstufe legen. Gemeinsam mit dem Herausführen des fertigen Stapels 1 werden alle Teilstapel um eine Stufenlänge weitergetaktet.FIG. 5 shows a finished stack of packaged goods 1, which is moved in the direction of the arrow by means of a step shifter 8 which can be moved back and forth in the longitudinal direction into a subsequent position shown in dash-dot lines on an exit table 9, for which purpose drivers 8a-8d of the step shifter 8 lie behind the respective stacking step. Together with the removal of the finished stack 1, all partial stacks are clocked on by one step length.

Durch den in Längsrichtung vor- und zurückbewegbaren Ausfuhrtisch 9 kann der herausgeführte Packgutstapel 1 auf einen definierten Ab­stand zum nachfolgenden Packgutstapel 1 gebracht werden, was ein stö­rungsfreies Zuführen des Packgutstapels in eine nachgeschaltete Sam­melpackmaschine sicherstellt.By means of the export table 9, which can be moved forwards and backwards in the longitudinal direction, the packaged goods stack 1 that is brought out can be brought to a defined distance from the subsequent packaged goods stack 1, which ensures a trouble-free feeding of the packaged goods stack into a downstream bulk packaging machine.

Wie im einzelnen aus der Figur 12 ersichtlich ist, befindet sich der Stufenschieber 8 an einem Wagen 11, der auf vom Maschinenrahmen 12 getragenen Führungsstangen 13 über nicht dargestellte Antriebsmittel in Längsrichtung vor und zurück verfahrbar ist.As can be seen in detail from FIG. 12, the step shifter 8 is located on a carriage 11, which can be moved back and forth in the longitudinal direction on guide rods 13 carried by the machine frame 12 via drive means, not shown.

Anhand der Figuren 6 bis 11 soll nachfolgend das automatische Ab­bauen der Stufenformation gemäß der Erfindung beschrieben werden.The automatic dismantling of the step formation according to the invention will be described below with reference to FIGS. 6 to 11.

Nach Fertigstellen eines Packgutstapels 1 wird dieser gemeinsam mit den Teilstapeln mittels des Stufenschiebers 8 um eine Stufenlänge weitergetaktet. Zum automatischen Abbau der Stufenformation wird die Packguteinheitensperre 4 über die programmierte Zählvorrichtung nun derart betätigt, daß der Fördereinrichtung 5 jeweils soviele Packgut­einheiten 1a zugeführt werden wie Teilstapel vorhanden sind.After completion of a stack of packaged goods 1, this is clocked together with the partial stacks by means of the step shifter 8 by a step length. To automatically break down the step formation, the packaged goods unit lock 4 is now actuated via the programmed counting device in such a way that as many packaged goods units 1a are supplied to the conveying device 5 as there are partial stacks.

Nach Herausführen eines fertiggestellten Packgutstapels 1 mittels des Stufenschiebers 8 verbleiben drei Teilstapel in der Stapelsta­tion, folglich werden von der Packguteinheitensperre 4 drei Packgut­einheiten 1a freigegeben, gegen den Anschlag 6 transportiert und an­gehoben, wobei die in der angehobenen Position gehaltenen Teilstapel mitangehoben werden (Fig. 6 und 7).After a finished packaged goods stack 1 has been brought out by means of the step shifter 8, three partial stacks remain in the stacking station; consequently, three packaged goods units 1a are released by the packaged goods unit lock 4, transported against the stop 6 and raised, the partial stacks held in the raised position also being lifted (FIG. 6 and 7).

Nach Fertigstellen eines weiteren Packgutstapels 1 und Heraustakten aus der Stapelstation verbleiben zwei Teilstapel und von der Sperre 4 werden nun zwei Packguteinheiten 1a freigegeben, bis zum Anschlag 6 weitertransportiert, angehoben, mit den Teilstapeln unter Mitnahme derselben zusammengeführt und in Position gehalten (Fig. 8 und 9).After completing another stack of packaged goods 1 and clocking out of the stacking station, two partial stacks remain and the lock 4 now releases two packaged goods units 1 a, is transported to the stop 6, raised, brought together with the partial stacks while taking them along and held in position (FIGS. 8 and 9).

Die Figuren 10 und 11 zeigen letztlich das Zuführen bis zum Anschlag 6, Anheben und Zusammenführen einer letzten Packguteinheit 1a mit dem verbleibenden letzten Teilstapel und Heraustakten aus der Stapel­station.FIGS. 10 and 11 ultimately show the feeding up to the stop 6, lifting and bringing together a last packaged goods unit 1 a with the remaining last partial stack and clocking out of the stacking station.

Um das erforderliche Hintergreifen der Teilstapel sowie jeweils des herauszuführenden Packgutstapels 1 zu ermöglichen, müssen die Mitneh­mer 8b-8d des Stufenschiebers 8 höhenverfahrbar sein. Hierzu werden diese am Wagen 11 in Führungsbahnen über einzelne Pneumatikzylinder 15 verschoben.In order to enable the required stacking of the partial stacks as well as the packaged goods stack 1 to be removed, the drivers 8b-8d of the step shifter 8 must be height-adjustable. For this purpose, they are moved on the carriage 11 in guideways via individual pneumatic cylinders 15.

Wie aus den Zeichnungen ersichtlich, sind oberhalb der Fördereinrich­tung 5 Lichtschranken 16 installiert, die den jeweiligen Stapelplät­zen zugeordnet sind, wobei die Lichtschranken als Kontrolleinrich­tung dienen und die Hubbewegung der Fördereinrichtung 5 derart steu­ern, daß diese erst dann einsetzt, nachdem die Packguteinheiten 1a die entsprechende Lichtschranke passiert haben und der Lichtstrahl unterbrochen ist.As can be seen from the drawings, 5 light barriers 16 are installed above the conveyor device, which are assigned to the respective stacking places, the light barriers serving as a control device and controlling the lifting movement of the conveyor device 5 in such a way that it only starts after the packaged goods units 1 a have the corresponding light barrier have passed and the light beam is interrupted.

In einer abgewandelten konstruktiven Ausgestaltung kann die Querför­dereinrichtung 5 als Rollenbahn mit angetriebenen Rollen sowie mit einem zwischen die Rollen fahrbaren Hubmittel ausgebildet sein.In a modified constructive embodiment, the cross conveyor 5 can be designed as a roller conveyor with driven rollers and with a lifting device that can be moved between the rollers.

Ein zweites Ausführungsbeispiel der erfindungsgemäßen Vorrichtung zeigt Figur 13, in der Flaschen als Packguteinheit 1b fortschreitend stufenförmig zu Packgutgruppen zusammengeführt werden. Der Stufen­schieber 8 befindet sich in dieser Ausführung in einer um 90° gekipp­ten Position über einer Plattform 20, auf welche die Flaschen 1b mit­tels eines Schiebers 21 von einer umlaufend angetriebenen Förderein­richtung 22 gemäß Pfeilrichtung abgeschoben werden.FIG. 13 shows a second exemplary embodiment of the device according to the invention, in which bottles are progressively brought together as packaged goods unit 1b to form packaged goods groups. In this embodiment, the step slide 8 is in a position tilted by 90 ° above a platform 20 onto which the bottles 1b are pushed by means of a slide 21 from a rotatingly driven conveyor 22 in the direction of the arrow.

Die Arbeitsweise entspricht dem Auf- und Abbau der Stufenformation in Vertikalebene, d. h. zum automatischen Aufbau der Stufenformation werden eine einzelne Flasche 1b, dann Reihen aus zwei, drei und mehr Flaschen jeweils nacheinander nach Freigabe von der Zuführeinrich­tung 3, 4 unter seitlicher Ausrichtung an einer außen liegenden orts­festen Begrenzungsschiene 23 und einer inneren ortsfesten zum Ab­schieben absenkbaren Begrenzungsschiene 24 über die Fördereinrich­tung 22 bis zum Anschlag 6 zugeführt und mittels des Schiebers 21 in Querrichtung um jeweils eine Stufe abgeschoben.The method of operation corresponds to the assembly and disassembly of the step formation in the vertical plane, ie for the automatic build-up of the step formation are a single bottle 1b, then rows of two, three and more bottles, one after the other, after release from the feed device 3, 4 with lateral alignment on an external stationary limiting rail 23 and an internal stationary limiting rail 24 which can be pushed down via the conveyor 22 to Stop 6 fed and pushed by one slide in the transverse direction by means of the slider 21.

Zum automatischen Abbau der Stufenformation werden dann alle in Quer­richtung verschobenen Flaschen 1b gemeinsam in Längsrichtung um eine Stufenlänge weitertransportiert und jeweils soviele Flaschen 1b bis zum Anschlag 6 zugeführt und in Querrichtung verschoben wie Teilgrup­pen vorhanden sind.For automatic dismantling of the step formation, all bottles 1b displaced in the transverse direction are then transported together in the longitudinal direction by a step length, and in each case as many bottles 1b are fed up to the stop 6 and displaced in the transverse direction as subgroups are present.

Im Hinblick auf eine funktionssichere Arbeitsweise sind die Flaschen 1b sowohl beim Abschieben von der Fördereinrichtung 22 als auch beim Weitertransport in Längsrichtung um eine Stufenlänge durch den Stu­fenschieber 8 im Bereich der Flaschenhälse zwischen Führungsschienen 25 geführt. Diese befinden sich gemeinsam an einem Tragteil und wer­den über nicht dargestellte Antriebsmittel mit der Bewegung des Stu­fenschiebers 8 synchron angetrieben. Gemäß der durch Pfeile angedeu­teten Umlaufbahn 26 bewegen sich die Führungsschienen 25 im Anschluß an das Vortakten in Längsrichtung aufwärts, zurück und abwärts in ihre Ausgangslage. Der Schieber 21 ist zudem als Formelement mit den Flaschenkonturen angepaßten Ausformungen 21a versehen, was ebenfalls einem funktionssicheren Transport der Flaschen 1b beim Querschieben zweckdienlich ist. Hierbei ist zu berücksichtigen, daß sich der Schieber 21 beim Einlauf der Flaschen 1b in einer den freien Zulauf ermöglichenden seitlichen Ausgangsposition befindet.With regard to a functionally reliable method of operation, the bottles 1b are guided by a step length through the step shifter 8 in the region of the bottle necks between guide rails 25 in the region of the bottle necks both when pushing away from the conveying device 22 and during further transport. These are located together on a support part and are driven synchronously with the movement of the step shifter 8 via drive means, not shown. According to the orbit 26 indicated by arrows, the guide rails 25 move upwards, backwards and downwards into their starting position following the pre-clocking. The slider 21 is also provided as a shaped element with the bottle contours adapted formations 21a, which is also useful for a functionally reliable transport of the bottles 1b during transverse sliding. It must be taken into account here that the slide 21 is in a lateral starting position allowing the free inlet when the bottles 1b enter.

Wie bereits eingangs im ersten Ausführungsbeispiel erwähnt, sind die Mitnehmer des Stufenschiebers 8 auch bei diesem Ausführungsbeispiel in Richtung auf den Schieber 21 verfahrbar, um die Flaschen 1b beim automatischen Abbau hintergreifen zu können, wozu die Mitnehmer 8b-8f auf Führungsbahnen 19 eines Aufnahmeteiles greifen und über nicht dargestellte Pneumatikzylinder betätigt werden.As already mentioned at the beginning in the first exemplary embodiment, the drivers of the step slide 8 can also be moved in this exemplary embodiment in the direction of the slide 21 in order to hold the bottles 1b to be able to reach behind automatic dismantling, for which purpose the drivers 8b-8f grip guideways 19 of a receiving part and are actuated via pneumatic cylinders (not shown).

Anstelle der dargestellten Führungsschienen 25 können selbstverständ­lich auch andere Elemente zum Halten der Flaschen 1b Verwendung fin­den, wie Bürstenanordnungen oder zwischen den Flaschenreihen angeord­nete Profilleisten.Instead of the guide rails 25 shown, other elements for holding the bottles 1b can of course also be used, such as brush arrangements or profile strips arranged between the rows of bottles.

In einer abgewandelten Arbeitsweise kann der automatische Aufbau der Stufenformation auch derart durchgeführt werden, daß eine einzelne Packguteinheit 1a, 1b bis in die erste Gruppierstufe zugeführt, in Querrichtung verfahren, ggf. in der angehobenen Position gehalten, und in Längsrichtung um eine Stufenlänge weitertransportiert wird, daß danach Reihen aus zwei, drei und mehr Packguteinheiten 1a, 1b bis jeweils in die zweite, dritte und weitere bis hin zur letzten Gruppierstufe zugeführt, in Querrichtung verfahren, mit den Teilgrup­pen zusammengeführt ggf. in der angehobenen Position gehalten und in Längsrichtung um eine Stufenlänge weitertransportiert werden. Dabei kann die Fördereinrichtung 5 oder 22 in den jeweiligen Gruppierstu­fen angehalten werden oder in den Gruppierstufen können einsteuer­bare Anschläge vorgesehen sein.In a modified mode of operation, the automatic formation of the step formation can also be carried out in such a way that a single packaged goods unit 1a, 1b is fed into the first grouping step, moved in the transverse direction, possibly held in the raised position, and transported in the longitudinal direction by a step length. that rows of two, three and more packaged goods units 1a, 1b are then fed into the second, third and further up to the last grouping stage, moved in the transverse direction, brought together with the subgroups, if necessary held in the raised position and in the longitudinal direction by a step length be transported further. The conveyor 5 or 22 can be stopped in the respective grouping stages or controllable stops can be provided in the grouping stages.
