Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verpacken von Reihen von Rollen, insbesondere von Papierrollen, die beispielsweise einen hohlen Kern aufweisen.The invention relates to a method and an apparatus for packaging rows of rolls, in particular paper rolls, which have, for example, a hollow core.

Beim Verpacken von Rollen besteht grundsätzlich ein erhöhter Platzbedarf, da der Platz zwischen den tangential aneinander anliegenden Rollen leer bleibt. Bei Rollen aus verformbaren Material ist es möglich, durch Anwendung von Druck die Rollen so zu verformen, daß ihr Querschnitt sich einem Quadrat oder Rechteck annähert. In diesem Fall verringert sich der freibleibende Raum zwischen den einzelnen Rollen.When packing rolls, there is basically an increased space requirement, since the space between the rolls lying tangentially against one another remains empty. In the case of rolls made of deformable material, it is possible to deform the rolls by applying pressure in such a way that their cross section approaches a square or rectangle. In this case, the free space between the individual roles is reduced.

Es ist bereits bekannt, Rollen für eine Verpackung dadurch zu komprimieren, daß zu einer Verpackungseinheit zusammengefaßte Reihen von Rollen von einer Seite her gegen einen Anschlag gedrückt werden.It is already known to compress rolls for packaging by pressing rows of rolls combined into a packaging unit from one side against a stop.

Da sich hierbei die Querabmessung der Rollen ändert, werden die äußeren Rollen von den inneren seitlich nach außen gedrückt. Hierbei kann es vorkommen, daß die Rollen dann im Endergebnis nicht mehr exakt ausgerichtet sind. Handelt es sich bei den Rollen um solche mit einem hohlen Kern, also beispielsweise um Rollen von Toilettenpapier oder Haushaltspapier, so tritt zusätzlich das Problem auf, daß dieser Kern unkontrolliert zusammengedrückt wird, wobei ggf. auch nach innen gerichtete Knicke auftreten. Da die Rollen hauptsächlich in dünne Kunstoffolie eingepackt werden, ergeben sich unschön aussehende Verpackungseinheiten, die vom Verbraucher nicht akzeptiert werden. Zusätzlich tritt bei den falsch zusammengedrückten Kernen das Problem auf, daß diese sich nur mit Mühe vom Verbraucher wieder zurückverformen lassen, was für die gängigen Papierrollenhalter aber notwendig ist.Since the transverse dimension of the rollers changes, the outer rollers are pushed laterally outwards by the inner ones. It can happen that the roles are no longer exactly aligned in the end result. If the rolls are those with a hollow core, for example rolls of toilet paper or household paper, then the problem additionally arises that this core is compressed in an uncontrolled manner, with inward creases possibly also occurring. Since the rolls are mainly packed in thin plastic film, there are unsightly looking packaging units that are not accepted by the consumer. In addition, the problem arises with the incorrectly compressed cores that they can only be deformed by the consumer with difficulty, which is necessary for the common paper roll holders.

Es ist bereits eine Vorrichtung zum Komprimieren von Reihen gleichförmiger Gegenstände in einen kompakten rechteckigen Block bekannt (US-A-2 962 848). Hierbei erfolgt die Komprimierung zwischen konvergierenden Seitenwänden, über die ein Riemen gespannt ist, der sich mit der gleichen Geschwindigkeit bewegt, mit der die zu komprimierenden Gegenstände weiterbewegt werden. Die Gegenstände weisen einen rechteckigen Querschnitt auf.An apparatus for compressing rows of uniform objects into a compact rectangular block is already known (US-A-2,962,848). The compression takes place between converging side walls, over which a belt is stretched, which moves at the same speed with which the objects to be compressed are moved on. The objects have a rectangular cross section.

Ebenfalls bekannt ist ein Mehrfachgebinde mit mehreren Hygienepapier-Rollen (DE-GM 91 05 053), bei dem die Papierrollen so verformt sind, daß die innere Papphülse unverändert bleibt, der Außenumfang sich aber einem viereckigen Querschnitt annähert. Zur Herstellung dieser Deformation sind zwei umflaufende Bänder vorgesehen, deren Abstand sich über ihre Längserstreckung verringert. Zwischen diese Bänder wird eine Papierrolle eingebracht, die von den Bändern transportiert und verformt wird. Da die Kernhülse jedoch nicht verformt, insbesondere nicht eingedrückt wird, spielt die Frage einer Ausrichtung der zusammengedrückten inneren Hülse keine Rolle.Also known is a multiple container with several hygienic paper rolls (DE-GM 91 05 053), in which the paper rolls are deformed in such a way that the inner cardboard sleeve remains unchanged, but the outer circumference approximates a square cross section. To produce this deformation, two circumferential bands are provided, the spacing of which decreases over their longitudinal extent. A paper roll is inserted between these belts, which is transported and deformed by the belts. However, since the core sleeve is not deformed, in particular is not pressed in, the question of an alignment of the compressed inner sleeve is irrelevant.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, bei der die verformten Rollen in ihrer Verpackungseinheit ein ordentliches Aussehen aufweisen. Bei Rollen mit einem hohlen Kern soll auch der hohle Kern gleichmäßig und in der gleichen Richtung zusammengedrückt sein, damit sich die Rollen durch einfaches Drücken auf ihre Stirnseiten wieder aufrichten, so daß sie in entsprechende Halter eingesetzt werden können.The invention has for its object to provide a method and an apparatus of the type mentioned, in which the deformed rollers have a neat appearance in their packaging unit. In the case of rolls with a hollow core, the hollow core should also be uniform and in the same Direction to be compressed so that the rollers straighten up again by simply pressing on their end faces so that they can be inserted into appropriate holders.

Zur Lösung dieser Aufgabe schlägt die Erfindung ein Verfahren mit den Merkmalen des Anspruchs 1 und eine Vorrichtung mit den Merkmalen des Anspruchs 8 vor. Weiterbildung der Erfindung sind Gegenstand der Unteransprüche.To achieve this object, the invention proposes a method with the features of claim 1 and a device with the features of claim 8. Further development of the invention are the subject of the dependent claims.

Durch die Beibehaltung der Ausrichtung während des Komprimierens und durch die seitliche Bewegung der Rollen wird dafür gesorgt, daß die Rollen immer in ihrer Reihe bleiben. Bei mit hohlen Kernen versehenen Rollen erfolgt ein Zusammendrücken dieser hohlen Kerne, so daß im Endzustand die Kerne als flache Hülsen vorhanden sind, die alle in einer Richtung senkrecht zu der Stauchrichtung ausgerichtet sind.Maintaining alignment during compression and moving the rollers sideways ensures that the rollers stay in line. In the case of rollers provided with hollow cores, these hollow cores are pressed together, so that in the final state the cores are present as flat sleeves which are all oriented in a direction perpendicular to the compression direction.

In Weiterbildung der Erfindung kann vorgesehen sein, daß mehrere Reihen von Rollen nebeneinander gebildet werden. Die Ausrichtung der einzelnen Reihen führt dazu, daß auch die mehreren Reihen ausgerichtet bleiben. Insbesondere kann vorgesehen sein, daß die Stauchung bei jeder Reihe von Rollen zu einem unterschiedlichen Zeitpunkt beginnt.In a development of the invention it can be provided that several rows of roles are formed side by side. The alignment of the individual rows means that the multiple rows remain aligned. In particular, it can be provided that the compression begins at a different point in time for each row of rolls.

Hierzu kann vorgesehen sein, daß während des Stauchens alle Reihen unterschiedliche Länge aufweisen.For this purpose it can be provided that all rows have different lengths during upsetting.

Die Erfindung schlägt in Weiterbildung vor, daß die Stauchung an der in Bewegungsrichtung vorderen Reihe der Rollen beginnen kann.The invention proposes in a further development that the compression can begin at the front row of the rollers in the direction of movement.

Aufgrund des unterschiedlichen Zeitpunkts des Beginns des Stauchens wirken sich die beim Stauchen auftretenden Verformungen gleichmäßiger aus, so daß das zu verpackende Endprodukt aus mehreren Reihen von Rollen ein sauberes Aussehen aufweist.Due to the different time of the beginning of the upsetting, the deformations occurring during the upsetting have a more uniform effect, so that the end product to be packaged has a clean appearance from several rows of rollers.

Erfindungsgemäß ist vorgesehen , daß die Verkürzung der Reihe dadurch bewirkt wird, daß sie zwischen zwei konvergierenden Seitenwänden hindurchbewegt wird. Der Grad der Konvergenz der beiden Seitenwände bestimmt das Ausmaß an Stauchung.It is provided according to the invention that the shortening of the row is brought about by moving it between two converging side walls. The degree of convergence of the two side walls determines the amount of compression.

Um während des Stauchens eine schonende Behandlung der Rollen zu gewährleisten, ist erfindungsgemäß vorgesehen , daß die Oberfläche der Seitenwände mit der Reihe mitbewegt wird. Dies kann beispielsweise dadurch geschehen, daß die Seitenwände insgesamt mit der Reihe mitbewegt werden, wozu Führungen vorgesehen sein können.In order to ensure that the rollers are treated gently during upsetting, the invention provides that the surface of the side walls is moved along with the row. This can be done, for example, by moving the side walls together with the row, for which purpose guides can be provided.

Erfindungsgemäß kann jedoch auch vorgesehen sein, daß ein sich über die Seitenwände erstreckendes Band mit der Reihe von Rollen mitbewegt wird. In diesem Fall können die Seitenwände können dann ortsfest angeordnet werden.According to the invention, however, it can also be provided that a belt extending over the side walls is moved along with the row of rollers. In this case, the side walls can then be arranged in a stationary manner.

Zur seitlichen Verschiebung wird erfindungsgemäß ein Schieber verwendet, der bei mehreren Reihen an der letzten Reihe angreift. Der Schieber kann insbesondere durch eine Stange gebildet werden.According to the invention, a slide is used for lateral displacement, which acts on the last row in several rows. The slide can in particular be formed by a rod.

Erfindungsgemäß ist vorgesehen , daß die Oberflächen der Seitenwände mit einer von der Schiebergeschwindigkeit verschiedenen Geschwindigkeit bewegt werden. Da der Schieber bei mehreren Reihen von Rollen an einer Reihe angreift und sich die in Bewegungsrichtung gemessene Querabmessung der Rollen aufgrund der Stauchung ändert, kann auf diese Weise das Ausrichten und das Beibehalten der gewünschten Form unterstützt werden. Dies gilt insbesondere dann, wenn die Reihen aus relativ vielen Rollen bestehen.According to the invention it is provided that the surfaces of the side walls are moved at a speed different from the slide speed. In this way, since the slide engages one row in the case of several rows of rollers and the transverse dimension of the rollers measured in the direction of movement changes due to the compression, the alignment and the maintenance of the desired shape can be supported. This is especially true if the rows consist of a relatively large number of roles.

Erfindungsgemäß kann vorgesehen sei, daß der Schieber durch einen Längsschlitz der Seitenwände hindurch verschoben wird, so daß es möglich wird, daß er mittig an den Rollen angreifen kann.According to the invention it can be provided that the slide is moved through a longitudinal slot in the side walls, so that it is possible that it can engage the rollers in the middle.

Die von der Erfindung vorgeschlagene Vorrichtung ist insbesondere zur Durchführung des Verfahrens geeignet. Sie enthält eine Ausrichteinrichtung, die die Rollen zu Reihen zusammenfaßt und diese gegenüber einer Linie ausrichtet. Es kann sich dabei vorzugsweise um eine Gerade handeln. Die Staucheinrichtung staucht die einzelnen Rollen, so daß sich die Reihen verkürzen. Die Transporteinrichtung bewegt die Rollen quer zur Stauchrichtung. Insbesondere kann vorgesehen sein, daß die Vorrichtung eine ebene Auflagefläche aufweist, auf der die Rollen mit ihren ebenen Seitenflächen aufliegen. Beim Transport werden die Rollen über diese Auflagefläche geschoben. Hierzu dient ein Schieber. Dieser Schieber kann sowohl die Ausrichtung als auch den Transport übernehmen.The device proposed by the invention is particularly suitable for carrying out the method. It contains an alignment device, which combines the rollers into rows and aligns them with a line. It can preferably be a straight line. The upsetting device upsets the individual rolls so that the rows are shortened. The transport device moves the rollers transversely to the compression direction. In particular, it can be provided that the device has a flat support surface on which the rollers rest with their flat side surfaces. The rollers are pushed over this support surface during transport. A slide is used for this. This slide can take care of the alignment as well as the transport.

Erfindungsgemäß ist vorgesehen, daß
die Staucheinrichtung zwei konvergierend angeordnete Seitenwände aufweist. Auf diese Weise läßt sich eine progressiv zunehmende Stauchung mit relativ einfachen Mitteln durchführen. Insbesondere ist dabei vorgesehen , daß sich über die Seitenwände ein angetriebenes Band erstreckt, beispielsweise in Form eines Riemens. Dieser vermindert die Reibung zwischen den jeweils letzten Rollen einer Reihe und den Seitenwänden. Insbesondere kann das Band auch dazu verwendet werden, die Ausrichtung und die Form der Reihe zu korrigieren, wozu es vorgesehen ist , daß die Geschwindigkeit des Bands der Seitenwände von der Geschwindigkeit des Schiebers abweicht.
According to the invention it is provided that
the upsetting device has two converging side walls. In this way, a progressively increasing compression can be carried out with relatively simple means. In particular, it is provided that a driven belt extends over the side walls, for example in the form of a belt. This reduces the friction between the last rolls in a row and the side walls. In particular, the tape can also be used to correct the alignment and shape of the row, for which it is intended that the speed of the tape of the side walls deviate from the speed of the slider.

Damit der Schieber etwa mittig an den Rollen angreifen kann, kann erfindungsgemäß vorgesehen sein, daß die Seitenwände zweiteilig zur Bildung eines Längsschlitzes ausgebildet sind, durch den der Schieber hindurchgeht.So that the slide can engage approximately centrally on the rollers, it can be provided according to the invention that the side walls are formed in two parts to form a longitudinal slot through which the slide passes.

Die zu verpackenden Papierrollen 1 werden der Vorrichtung in Reihen mit Hilfe eines Förderbands 2 zugeliefert, in denen die Rollen koaxial ausgerichtet sind. In dieser Orientierung kommen die Papierrollen von der Fertigung, da die Papierrollen als lange Rollen hergestellt und anschließend zerschnitten werden. Mit Hilfe eines Sternrads 3 werden die einzelnen Rollen aufgerichtet, d. h. in eine Position gebracht, in der die Achse der Rolle 1 vertikal verläuft. Das Sternrad 3 weist zwei Scheiben 4 auf, die beide parallel zueinander mit einem gewissen Abstand angeordnet sind. Die einzelnen Aufnahmepositionen 5 des Sternrads 3 enthalten jeweils eine radial verlaufende Auflagefläche 6, die der zylindrischen Mantelfläche der Rollen 1 zugeordnet ist, sowie eine senkrecht hierzu verlaufende Auflagefläche 7, die der ebenen Seitenfläche 8 der Rollen 1 zugeordnet ist.The paper rolls 1 to be packed are supplied to the device in rows by means of a conveyor belt 2, in which the rolls are aligned coaxially. In this orientation, the paper rolls come from production, since the paper rolls are produced as long rolls and then cut. With the help of a star wheel 3, the individual rollers are erected, ie brought into a position in which the axis of the roller 1 runs vertically. The star wheel 3 has two disks 4, both of which are arranged parallel to one another at a certain distance. The individual receiving positions 5 of the star wheel 3 each contain a radially running support surface 6, which is assigned to the cylindrical outer surface of the rollers 1, and a perpendicularly running support surface 7, which is assigned to the flat side surface 8 of the rollers 1.

Zwischen den beiden Scheiben 4 erstreckt sich im oberen Bereich des Sternrads ein Förderband 9, das über zwei Walzen 10 herumgeführt ist. Eine Walze 10 ist angetrieben. Sobald eine einzelne Rolle 1 aufgerichtet ist, gelangt sie auf das an dieser Stelle angeordnete Förderband 9, das die Rolle 1 dann horizontal weiterverschiebt, bis sie außerhalb des Umfangs des Sternrads 3 angeordnet ist. Das Förderband 9 schiebt die Rolle 1 dann soweit wie möglich bis auf eine ebene Auflagefläche 11.A conveyor belt 9 extends between the two disks 4 in the upper region of the star wheel and is guided around over two rollers 10. A roller 10 is driven. As soon as a single roller 1 is erected, it arrives at the conveyor belt 9 arranged at this point, which then moves the roller 1 horizontally further until it is arranged outside the circumference of the star wheel 3. The conveyor belt 9 then pushes the roller 1 as far as possible up to a flat contact surface 11.

Um die grade auf die Auflagefläche 11 aufgesetzte Rolle 1 weiterzubefördern, ist ein erster Schieber 12 vorgesehen. Dieser Schieber 12 enthält beidseits der Bewegungsbahn zwei umlaufende Riemen, Ketten oder dgl. 13, die um zwei Räder 14 herumgelegt ist. Zwischen den beiden Ketten 13 erstreckt sich eine Stange 15, die also senkrecht zur Papierebene verläuft. Bei Antreiben eines der beiden Räder 14 in Richtung des Pfeiles 16 bewegt sich die Stange 15 so, daß sie an der in Fig. 1 rechten Mantelfläche der Rolle 1 angreift und diese weiter auf die Auflagefläche 11 aufschiebt. Der Schieber 15 kann die Rolle 1 bis in den Bereich der folgenden Staucheinrichtung 17 schieben.A first slide 12 is provided in order to further convey the roller 1 which has just been placed onto the bearing surface 11. This slide 12 contains two circumferential belts, chains or the like 13 on both sides of the movement path, which is placed around two wheels 14. A rod 15 extends between the two chains 13 and thus runs perpendicular to the plane of the paper. When driving one of the two wheels 14 in the direction of arrow 16, the rod 15 moves so that it engages the right lateral surface of the roller 1 in FIG. 1 and pushes it further onto the contact surface 11. The slider 15 can push the roller 1 into the area of the following upsetting device 17.

Das Stirnrad 3 liefert die Rollen 1 mit Abstand hintereinander an. Die Vorrichtung enthält, wie im folgenden noch dargestellt werden wird, mehrere derartige Stirnräder 3, so daß der Staucheinrichtung 17 auch mehrere Rollen 1 zugeführt werden, die jeweils senkrecht zur Papierebene verlaufende Reihen von Rollen bilden.The spur gear 3 delivers the rollers 1 at a distance one behind the other. The device contains, as will be shown in the following, a plurality of such spur gears 3, so that the upsetting device 17 is also supplied with a plurality of rollers 1, which each form rows of rollers running perpendicular to the plane of the paper.

Sobald beispielsweise vier Reihen von Rollen 1 auf der Auflagefläche 11 nebeneinander angeordnet sind, und jetzt eine Stauchung dieser zu einer Verpackung gehörenden Reihen durchgeführt werden soll, tritt ein zweiter Schieber 18 in Funktion, der in ähnlicher Weise aufgebaut ist wie der Schieber 12. Beidseits der Bewegungsbahn sind also Ketten, Riemen oder dgl. 19 angeordnet, die sich über zwei Zahnräder, Riemenscheiben 20 oder dgl. erstrecken. Zwischen beiden Ketten erstreckt sich an der gleichen Stelle quer zur Papierebene eine das Angriffselement des Schiebers 18 bildende Stange 21. Sobald die Stange längs des Riemens 19 zu der in Fig. 1 rechten Riemenscheibe 20 gelangt ist und dort nach oben geführt wird, schiebt sie die mehreren Reihen von Rollen in die Staucheinrichtung 17 ein. Dabei erfolgt eine Ausrichtung an der Stange 21 selbst. Die nun mehreren Reihen von Rollen 1 werden von der Stange 21 des Schiebers 18 zwischen zwei Seitenwänden 22 hindurchgeschoben, von denen der Schnitt der Fig. 1 nur eine Seitenwand 22 zeigt. Die Seitenwände 22 enthalten einen oberen Teil 22a und einen unteren 22b, zwischen denen ein Längsschlitz 23 gebildet ist. Der Längsschlitz 23 verläuft in Bewegungsrichtung parallel zu der Auflagefläche 11, so daß die Stange 21 über die gesamte Länge der Seitenwände 22 bewegt werden kann.As soon as, for example, four rows of rollers 1 are arranged next to one another on the support surface 11 and a compression of these rows belonging to a package is to be carried out, a second slide 18 comes into operation, which is constructed in a similar manner to the slider 12. Chains, belts or the like. 19 are thus arranged on both sides of the movement path, which extend over two toothed wheels, pulleys 20 or the like. Between the two chains extends at the same point transversely to the plane of the paper a rod 21 forming the engagement element of the slider 18. As soon as the rod has reached along the belt 19 to the right pulley 20 in FIG. 1 and is guided up there, it pushes it a plurality of rows of rollers in the upsetting device 17. An alignment takes place on the rod 21 itself. The now several rows of rollers 1 are pushed by the rod 21 of the slide 18 between two side walls 22, of which the section of FIG. 1 shows only one side wall 22. The side walls 22 include an upper portion 22a and a lower portion 22b, between which a longitudinal slot 23 is formed. The longitudinal slot 23 runs in the direction of movement parallel to the bearing surface 11, so that the rod 21 can be moved over the entire length of the side walls 22.

Am Ende der Staucheinrichtung 17 ist ein Anschlag 24 angeordnet, der mit Hilfe einer umlaufenden Kette 25 oder eines Riemens wegbewegt werden kann.At the end of the upsetting device 17 there is a stop 24 which can be moved away with the aid of a circulating chain 25 or a belt.

In Fig. 2 ist die Aufsicht auf die Vorrichtung zu sehen. Zunächst wird auf die rechte Hälfte der Fig. 2 verwiesen, wo ein Förderband 2 dargestellt ist, das zum Heranfördern der Rollen 1 dient. Auf dem dargestellten Förderband ist noch Platz für zwei weitere Reihen von Rollen, so daß insgesamt vier Reihen von Rollen 1 angeliefert werden. Für jede Reihe von Rollen 1 auf dem Förderband 2 ist ein Sternrad 3 vorgesehen, von denen in Fig. 2 nur eins dargestellt ist. Die Bewegung des Sternrads 3 erfolgt um eine Achse 26, die auch für die anderen Sternräder dienen kann. Damit ist eine Synchronisierung der Bewegung der Sternräder 3 gegeben.The top view of the device can be seen in FIG. First, reference is made to the right half of FIG. 2, where a conveyor belt 2 is shown, which is used to convey the rollers 1 up. On the conveyor belt shown there is still space for two further rows of rolls, so that a total of four rows of rolls 1 are delivered. A star wheel 3 is provided for each row of rollers 1 on the conveyor belt 2, of which only one is shown in FIG. 2. The movement of the star wheel 3 takes place about an axis 26, which also can serve for the other star wheels. The movement of the star wheels 3 is thus synchronized.

Ebenfalls aus Fig. 1 ist zu sehen der Abstand der beiden das Sternrad 3 bildenden Scheiben, zwischen denen das Förderband 9 zu sehen ist.1 also shows the distance between the two disks forming the star wheel 3, between which the conveyor belt 9 can be seen.

Das Sternrad 3 und das Förderband 9 sammeln die einzelnen Rollen 1 und befördern sie zusammen mit dem Schieber 12 auf die ebene Auflagefläche 1. Sobald dort beispielsweise vier Reihen von Rollen 1 vorhanden sind, werden sie von dem Schieber 18 übernommen und zwischen die Seitenwände 22 eingeschoben. Die Seitenwände 22 weisen sowohl in ihrem oberen Teil 22a als auch in ihrem unteren Teil 22b ein umlaufendes Band 27 auf, das beispielsweise über einen Kern abgestützt ist.The star wheel 3 and the conveyor belt 9 collect the individual rollers 1 and convey them together with the slider 12 onto the flat support surface 1. As soon as, for example, four rows of rollers 1 are present, they are taken over by the slider 18 and inserted between the side walls 22 . The side walls 22 have a circumferential band 27 both in their upper part 22a and in their lower part 22b, which is supported, for example, by a core.

In Fig. 2 ist die Stange 21 des Schiebers 18 in einer Position dargestellt, in der die unmittelbar an der Stange 21 anliegende Reihe von Rollen 1 noch unverformt ist. Die weiteren insgesamt beispielsweise vier Reihen von Rollen sind nicht dargestellt, da sich das Komprimieren bzw. Stauchen auch an einer Reihe darstellen läßt. Die Rollen 1 werden nun von der Stange 21 zwischen den Seitenwänden 22 seitlich verschoben, wozu sowohl die Riemen 19 als auch die Bänder 27 angetrieben werden. Die Reihe wird verkürzt und die Rollen 1 gestaucht. Dabei vergrößert sich die Querabmessung der Rollen in Richtung der Bewegung. Am Ende der konvergierenden Seitenwände 22 nimmt die Reihe von Rollen 1 dann die links dargestellte Stellung ein, bei der sich der Umfang der Rollen 1 einem abgerundeten Rechteck annähert und die die hohlen Kerne bildenden Hülsen 28 zusammengedrückt sind. Die flachen Hülsen 28 sind alle in der gleichen Richtung ausgerichtet. An dem links in Fig. 2 angeordneten Abgabeende der Vorrichtung im Bereich der engsten Stelle zwischen den beiden Seitenwänden 22 kann jetzt eine Überführung in einen Beutel erfolgen, der die Verpackung bildet.In Fig. 2 the rod 21 of the slide 18 is shown in a position in which the row of rollers 1 lying directly on the rod 21 is still undeformed. The other four rows of rolls, for example, are not shown, since the compression or compression can also be shown on one row. The rollers 1 are now moved laterally by the rod 21 between the side walls 22, for which purpose both the belts 19 and the belts 27 are driven. The row is shortened and the rolls 1 are compressed. The transverse dimension of the rollers increases in the direction of movement. At the end of the converging side walls 22, the row of rollers 1 then assumes the position shown on the left, in which the circumference of the rollers 1 approximates a rounded rectangle and the sleeves 28 forming the hollow cores are compressed. The flat sleeves 28 are all aligned in the same direction. At the dispensing end of the device arranged on the left in FIG. 2 in the area of the narrowest point between the two side walls 22 now transfer into a bag that forms the packaging.

Fig. 3 zeigt eine der Fig. 2 ähnliche Aufsicht auf eine Vorrichtung, bei der sich an die durch die konvergierenden Seitenwände 22 gebildete Staucheinrichtung noch eine weitere Einrichtung anschließt, bevor die verformten Papierrollen 1 verpackt werden können. An das noch in Fig. 2 zu sehende Ende der Staucheinrichtung schließen sich zwei parallel zueinander verlaufende Aufreihbänder 30 an, deren Länge so bemessen ist, daß gerade zwei Reihen von verformten Papierrollen 1 zwischen ihnen gehalten werden können. Diese beiden Reihen entsprechen beispielsweise gerade einer Verpackungseinheit.FIG. 3 shows a plan view similar to that of FIG. 2, in which a further device is connected to the upsetting device formed by the converging side walls 22 before the deformed paper rolls 1 can be packed. At the end of the upsetting device, which can still be seen in FIG. 2, there are two parallel rows 30, the length of which is such that just two rows of deformed paper rolls 1 can be held between them. For example, these two rows correspond to one packaging unit.

An die beiden Aufreihbänder 30 schließen sich in geradliniger fluchtender Verlängerung zwei Überleitbänder 31 an, die dazu dienen, einen Stapel in die eigentliche Verpackungseinrichtung überzuleiten. Die Verpackungseinrichtung kann in Verlängerung der Überleitbänder 31 nochmals eine stationäre Presse aufweisen, falls die verformten Papierrollen 1 nochmals weiter komprimiert werden sollen. Dies kann dann durch einfaches Aufbringen von Druck erfolgen, da die hohlen Kerne 28 zu diesem Zeitpunkt bereits zusammengeklappt und ausgerichtet sind. Dieser Teil der Vorrichtung wird daher nicht weiter beschrieben.Two transfer belts 31, which serve to transfer a stack into the actual packaging device, adjoin the two aligning belts 30 in a rectilinear, aligned extension. In extension of the transfer belts 31, the packaging device can again have a stationary press if the deformed paper rolls 1 are to be compressed further. This can then be done by simply applying pressure, since the hollow cores 28 are already folded and aligned at this point in time. This part of the device is therefore not described further.

Die Aufreihbänder 30 und die Überleitbänder 31 sind in ähnlicher Weise aufgebaut wie die Seitenwände 22, siehe insbesondere Fig. 2, so daß also auch dort durch einen Längsschlitz die Querstange 32 eines Schiebers 33 hindurchgeschoben werden kann, um die Stapel von Papierrollen zusammen mit den umlaufenden Bändern korrekt zu transportieren. Der Schieber 33 enthält wiederum, ähnlich wie der Schieber 18, umlaufende Ketten, zwischen denen sich die Stange 32 ertreckt.The aligning belts 30 and the transfer belts 31 are constructed in a similar manner to the side walls 22, see in particular FIG. 2, so that the transverse rod 32 of a slide 33 can also be pushed through a longitudinal slot there in order to stack the paper rolls together with the rotating ones Transport belts correctly. The slider 33 in turn contains, like the slider 18, revolving chains, between which the rod 32 extends.

Beispielsweise kann der Schieber 33 eine obere Stabförderkette aufweisen, damit die beiden Stabförderer nicht in Konflikt gelangen.For example, the slider 33 can have an upper bar conveyor chain so that the two bar conveyors do not come into conflict.

Bei der Art der Stauchung der Rollen, wie sie von der erfindungsgemäßen Vorrichtung nach dem erfindungsgemäßen Verfahren durchgeführt wird, können die sich verkürzenden und verbreiternden Reihen von Rollen ihre gegenseitige Ausrichtung beibehalten.With the type of compression of the rollers, as is carried out by the device according to the invention by the method according to the invention, the shortening and widening rows of rollers can maintain their mutual alignment.
