So that additional labels can be applied, an intermediate cylinder (7) is arranged between an application folding tongs cylinder (9) which applies the labels and the accepting folding cylinder (6) and together with the application folding tongs cylinder (9) forms a nip into which labels torn from a second web of material (10) along perforated lines pass and which delivers the labels torn from the first and the second webs of material to the continuous web or the moving workpieces (12), the said labels at least partly overlapping one another. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Aufbringen vorzugsweise beleimter Zettel oder Schlauchstücke auf eine laufende Bahn oder auf durchlaufende Werkstücke, vorzugsweise auf die aufgezogenen und noch offenen Böden von Säcken, mit Vorzugsrollenpaaren für eine Materialbahn und Einrichtungen zum Perforieren und Abreißen oder Einrichtungen zum Abtrennen der Zettel oder Schlauchstücke von der Materialbahn und mit einem Übernahmefalzzangenzylinder zur Übernahme und anschließenden Abgabe der Zettel oder Schlauchwerkstücke.The invention relates to a device for applying preferably glued pieces of paper or tubular pieces to a running web or to continuous workpieces, preferably to the opened and still open bottoms of sacks, with pairs of preferred rollers for a material web and devices for perforating and tearing off or devices for separating the papers or Pieces of hose from the material web and with a takeover plier cylinder for taking over and then delivering the notes or hose workpieces.

Werden die Zettel auf die aufgezogenen und noch offenen Böden von Säcken aufgebracht, handelt es sich um Verschlußriegel oder Verstärkungszettel oder Ventile. Eine aus der DE-PS 11 79 087 bekannte Vorrichtung der eingangs angegebenen Art zieht gleichzeitig von zwei Vorratsrollen eine Papierbahn und eine Kunststoffbahn in übereinanderliegender Form ab, wobei die zweilagige Bahn durch perforierende Messer im Abstand der Zettel mit Querperforationen versehen wird. Eine Bahn wird anschließend durch eine Leitrolle abgehoben und unter Versatz wieder auf die andere Bahn aufgelegt. Von der Bahn werden dann relativ zueinander versetzte Doppelblätter dadurch abgerissen, daß das vordere Ende der Doppelbahn von Falzzangen des Übernahmefalzzangenzylinders erfaßt und die Bahn hinter den Perforationslinien festgehalten wird. Die von dem Übernahmezangenzylinder transportierten Zettel werden dann von einer Klebstoffauftragswalze einer Klebstoffauftragsvorrichtung formatmäßig mit Leimaufträgen versehen und anschließend werden die Zettel von dem Übernahmefalzzangenzylinder auf die tangential zu diesem durchlaufenden geöffneten Böden aufgebracht. Durch Zulegen der Böden bildet sich an jedem Boden dann ein Einfüllventil, wobei die Kunststofflage der Doppelzettel weiter in das Innere des Sackes hineinragt als die Papierlage, so daß das nach innen vorstehende Ende des Kunststoffschlauchstücks sich unter dem Fülldruck zusammenlegen und seine Dichtfunktion ausüben kann.If the notes are applied to the opened and still open bottoms of sacks, they are locking bolts or reinforcement labels or valves. A known from DE-PS 11 79 087 device of the type mentioned simultaneously pulls from two supply rolls a paper web and a plastic web in a superimposed form, the two-layer web by perforating knife at a distance from the slip with cross perforations is provided. A web is then lifted off by a guide roller and placed on the other web with an offset. Double sheets which are offset relative to one another are then torn off from the web in that the front end of the double web is gripped by folding pliers of the take-over plier cylinder and the web is held behind the perforation lines. The notes transported by the take-over plier cylinder are then formatted with glue applications by an adhesive application roller of an adhesive application device, and then the notes are applied by the take-over plier cylinder to the open floors which pass tangentially to it. By adding the bottoms, a filling valve is then formed on each bottom, the plastic layer of the double label protruding further into the inside of the sack than the paper layer, so that the inwardly projecting end of the piece of plastic tube can collapse under the filling pressure and perform its sealing function.

Es gibt Anwendungsfälle, in denen es erforderlich ist, zusätzlich zu dem von einer Bahn abgerissenen Zettel oder dem von einer doppelt liegenden Bahn abgerissenen Doppelzettel einen weiteren Zettel oder Schlauchstück aufzubringen, um anderen Fertigungsanforderungen gerecht zu werden.There are applications in which it is necessary, in addition to the sheet torn off a sheet or the double sheet torn off a double-lying sheet, to apply another sheet or piece of hose in order to meet other production requirements.

Beispielsweise besteht in der Praxis das Bedürfnis, auf die auf den Boden aufgebrachten Zettel ein zusätzliches Schlauchstück aufzubringen, das kürzer ist als die Zettel und im zugelegten Zustand des Bodens nach außen hin vorsteht, so daß nach dem Befüllen des Sackes die Möglichkeit geschaffen ist, diesen durch Verschweißen oder Verkleben des nach außen über den Boden überstehenden Schlauchstücks dicht zu verschließen.For example, in practice there is a need to apply an additional piece of tubing to the notes attached to the floor, which is shorter than the notes and protrudes outwards when the bottom is closed, so that after filling the bag the possibility is created of this to be sealed tightly by welding or gluing the piece of hose projecting beyond the floor to the outside.

In anderen Fällen ist es erforderlich, die Ventile mit einer Entlüftungseinrichtung zu versehen, so daß in dem Sack eingeschlossene Luft entweichen kann. Dies geschieht dadurch, daß das Ventil zumindest teilweise von einem Vliesstreifen eingehüllt wird, der ein Entweichen von Luft gestattet.In other cases it is necessary to provide the valves with a venting device so that air trapped in the sack can escape. This happens because the valve is at least partially enveloped by a fleece strip that allows air to escape.

Um einen zusätzlichen Zettel oder ein Schlauchstück auf den oder die Ventilzettel aufzubringen oder um das aus den Ventilzettel geformte Füllventil mit einer der Entlüftung dienenden Vlieslage zu umgeben, ist es bei der bekannten Vorrichtung erforderlich, in Durchlaufrichtung des Sackbodens gesehen, dieser eine weitere Einrichtung nachzuschalten, durch die von einer Schlauchbahn einzelne Stücke abgetrennt und in den offenen Boden auf die bereits aufgebrachten Zettel aufgelegt werden, oder aber der Vorrichtung eine Einrichtung vorzuschalten, die beispielsweise der Entlüftung dienende Vliesstreifen aufbringt. Um also die bekannte Vorrichtung in der beschriebenen Weise zu erweitern, müssen zusätzliche Aggregate vorgesehen werden, die die Baulänge der Anlage verlängern und die Anlage verteuern. Weiterhin ist es bei der bekannten Vorrichtung nur mit einem unvertretbaren Aufwand möglich, diese in der Weise nachzurüsten, daß dieser Einrichtungen zum Aufbringen zusätzlicher Zettel oder von Vliesstreifen vor- und/oder nachgeschaltet sind.In order to apply an additional piece of paper or a piece of tubing to the valve label (s) or to surround the filling valve formed from the valve label with a non-woven layer serving for ventilation, it is necessary in the known device, in the direction of passage of the bag bottom, to connect it to a further device, by separating the individual pieces from a tube sheet and placing them in the open floor on the pieces of paper that have already been applied, or to connect the device with a device which, for example, applies non-woven strips for ventilation. In order to expand the known device in the manner described, additional units must be provided which extend the overall length of the system and make the system more expensive. Furthermore, it is only possible with an unacceptable effort in the known device to retrofit it in such a way that these devices are connected upstream and / or downstream for applying additional notes or fleece strips.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich in wirtschaftlicher Weise zusätzliche Zettel, Schlauchstücke oder Vlieseinlagen auf Werkstücke und insbesondere Böden von Säcken aufbringen lassen. Dabei soll die Vorrichtung so ausgestaltet sein, daß sich deren Baulänge grundsätzlich nicht vergrößert. Weiterhin soll die Möglichkeit geschaffen werden, bereits bestehende Vorrichtungen und Anlagen mit einem vertretbaren Aufwand nachzurüsten.The object of the invention is therefore to provide a device of the type specified at the outset, with which additional notes, pieces of tubing or fleece inserts can be applied economically to workpieces and in particular to the bottom of sacks. The device should be designed so that its overall length does not increase in principle. Furthermore, the possibility is to be created to retrofit existing devices and systems with reasonable effort.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß zwischen einem die Zettel und/oder Schlauchstücke aufbringenden Aufbringefalzzangenzylinder und dem Übernahmefalzzylinder ein Zwischenzylinder angeordnet ist, der mit dem Aufbringefalzzylinder einen Walzenspalt bildet, in den von einer zweiten Materialbahn längs Perforationslinien abgerissene oder abgetrennte Zettel oder Schlauchstücke einlaufen, und der die von der ersten und der zweiten Materialbahn abgerissenen oder abgetrennten Zettel oder Schlauchstücke ineinander zumindest teilweise überlappender Form an die durchlaufenden Werkstücke bzw. Böden abgibt. Bei der erfindungsgemäßen Vorrichtung sind zum Aufbringen zusätzlicher Zettel, Schlauchstücke oder Einlagen komplette Aufbringevorrichtungen vermieden, da die zusätzlichen Zettel, Schlauchstücke oder Einlagen bereits vor dem Aufbringen auf die Böden oder Werkstücke miteinander zu aufzubringenden Einheiten vereinigt werden, die dann formatrichtig durch einen Arbeitsschritt gemeinsam aufgebracht werden. Die erfindungsgemäße Vorrichtung führt daher nicht nur zu einer Verkürzung der Baulänge, sondern insbesondere auch zu einer Einsparung von Auftragswalzen, da zwei Zettellinien auf einen gemeinsamen Aufbringefalzzangenzylinder arbeiten.According to the invention, this object is achieved in a device of the generic type in that an intermediate cylinder is arranged between an application folder plier cylinder applying the pieces of paper and / or hose pieces and the take-over folder cylinder, which forms a nip with the application folder cylinder, in the longitudinal direction of a second material web Lines of perforation torn or separated pieces of paper or hose run in, and which delivers the pieces of paper or hose pieces torn or separated from one another in the at least partially overlapping form to the continuous workpieces or floors. In the device according to the invention, complete application devices are avoided for the application of additional notes, hose pieces or inserts, since the additional notes, hose pieces or inserts are combined with one another to be applied to units to be applied before application to the floors or workpieces, which units are then applied together in the correct format by one work step . The device according to the invention therefore not only leads to a shortening of the overall length, but in particular also to a reduction in the number of application rollers, since two scoring lines work on a common applicator folding cylinder.

Nach einer vorteilhaften Ausgestaltung ist vorgesehen, daß der Zwischenzylinder mit einer Nadelreihe o.dgl. zur Übernahme der Zettel o.dgl. von dem Übernahmezylinder versehen ist.According to an advantageous embodiment it is provided that the intermediate cylinder or the like with a row of needles. to take over the notes or the like. is provided by the takeover cylinder.

An den Zwischenzylinder kann ein Leimauftragswalze eines Beleimwerkes angestellt sein, die die Zettel o.dgl. mit formatmäßigen Leimaufträgen versieht.On the intermediate cylinder, a glue application roller of a gluing plant can be employed, which the like or the like. with format-based glue applications.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß der Zwischenzylinder in Drehrichtung vor der Nadelreihe mit einer Falzleiste o.dgl. versehen ist, die das vorauslaufende Ende des von der zweiten Materialbahn abgerissenen oder abgetrennten Zettels o.dgl. in eine Falzzange des Aufbringezylinders einschiebt. Beim weiteren Durchlauf kommt dann der auf dem Zwischenzylinder gehalterte Zettel oder Doppelzettel mit seinem Leimauftrag mit dem von der zweiten Materialbahn abgerissenen Zettel o.dgl. in Berührung und verklebt mit diesem, so daß er von dem auf dem Aufbringezylinder durch die Falzzangen gehalterten Zettel o.dgl. mitgenommen und zusammen mit diesen auf das Werkstück oder den offenen Boden aufgebracht wird.According to an advantageous embodiment of the invention it is provided that the intermediate cylinder or the like in the direction of rotation in front of the row of needles with a folding strip. is provided, or the like, the leading end of the piece of paper torn or separated from the second material web. into a folding pliers of the application cylinder. During the further run, the slip or double slip held on the intermediate cylinder then comes with its glue application with the slip or the like torn off from the second material web. in contact and glued to it so that it or the like from the note held on the application cylinder by the folding pliers. taken along with them is applied to the workpiece or the open floor.

Zweckmäßigerweise ist an dem Aufbringezylinder eine Leimauftragswalze eines zweiten Beleimwerkes angestellt, die die Zettel, Schlauchstücke oder Einlagen, die von der zweiten Materialbahn abgerissen oder abgetrennt worden sind, formatmäßig mit Leimaufträgen versieht.A glue applicator roller of a second gluing unit is expediently attached to the application cylinder, which provides the adhesive, format, or adhesive strips that have been torn off or separated from the second material web.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur eine Vorrichtung zum Aufbringen von kombinierten Zettel- und/oder Schlauchstückpaketen, deren Zettel und/oder Schläuchestücken von getrennt zugeführten Materialbahnen abgerissen worden sind, auf die aufgezogenen Sackböden schematisch in Seitenansicht dargestellt ist, näher erläutert.An embodiment of the invention is shown below with reference to the drawing, in the single figure of which a device for applying combined note and / or tube packs, the notes and / or tube pieces of which have been torn off from separately fed material webs, is shown schematically in side view on the sack bottoms that have been pulled up , explained in more detail.

Eine zweilagige Bahn 1, deren eine Lage aus Papier und deren andere Lage aus Kunststoff besteht, die von nicht dargestellten Vorratsrollen abgezogen werden, werden von dem Vorzugswalzenpaar 2 vorgezogen. Dem Vorzugswalzenpaar 2 ist ein weiteres Vorzugswalzenpaar 3 nachgeordnet, wobei zwischen den beiden Walzenpaaren 2 und 3 die Querperforationseinrichtung 4 sowie Umlenkrollen 5 angeordnet sind, durch welche die Kunststoffbahn gegenüber der Papierbahn in Längsrichtung versetzt wird. Das Abreißen der einzelnen zweilagigen Bahnstücke findet zwischen dem Vorzugswalzenpaar 3 und dem Falzzangenzylinderpaar 6 statt, von denen der mit den Falzzangen versehene Zylinder den Weitertransport des Doppelblattes übernimmt. Bis hierher ist die Vorrichtung mit der aus der DE-PS 11 79 087 bekannten Vorrichtung vergleichbar.A two-layer web 1, one layer of which is made of paper and the other of which is made of plastic, which are drawn off from supply rolls, not shown, are preferred by the pair of feed rollers 2. The preferred pair of rollers 2 is followed by a further pair of preferred rollers 3, the transverse perforation device 4 and deflection rollers 5 being arranged between the two pairs of rollers 2 and 3, by means of which the plastic web is offset in the longitudinal direction with respect to the paper web. The tearing off of the individual two-layer web pieces takes place between the pair of preferred rollers 3 and the pair of folding pliers cylinders 6, of which the cylinder provided with the folding pliers takes over the further transport of the double sheet. So far, the device is comparable to the device known from DE-PS 11 79 087.

Der Falzzangenzylinder des Zylinderpaares 6 übergibt dann das Doppelblatt an einen als Zwischenzylinder ausgestalteten Übergabezylinder 7. Dieser führt das Blatt bzw. Doppelblatt an einer Beleimeinrichtung 8 vorbei, durch die dann die Innenseite der Zettel formatmäßig mit einem Leimauftrag versehen wird.The folding pliers cylinder of the pair of cylinders 6 then transfers the double sheet to a transfer cylinder 7 designed as an intermediate cylinder. This leads the sheet or double sheet past a gluing device 8, through which the inside of the slip is then sized with a glue application.

Der Übernahme- oder Zwischenzylinder 7 ist zum Zwecke der Übernahme der Zettel bzw. Doppelzettel mit einer Nadelreihe versehen, vor der in Umlaufrichtung gesehen eine Falzleiste oder ein Falzschwert angeordnet ist. Der von dem Falzzangenzylinderpaar 6 abgerissene Doppelzettel wird von der nicht dargestellten Nadelreihe des Übernahme- oder Zwischenzylinders 7 gehalten.The take-over or intermediate cylinder 7 is provided with a row of needles for the purpose of taking over the slips or double slips, in front of which a folding bar or a folding sword is arranged, as seen in the direction of rotation. The double label torn off from the pair of folding pliers 6 is held by the row of needles, not shown, of the takeover or intermediate cylinder 7.

Bei weiterer Drehung des Zwischenzylinders 7 gelangt dann die der Nadelreihe vorgeordnete Falzleiste in Kontakt mit der an dem Aufbringefalzzangenzylinder 9 angebrachten Falzzange, so daß das vorauslaufende Ende einer Schlauchbahn 10 von der Falzzange gehalten und dadurch von dieser ein Schlauchstück längs einer Querperforationslinie abgerissen wird. Die Zuführung der Schlauchbahn 10 wird nachstehend noch näher beschrieben. Dieses Schlauchstück verklebt sodann mit der zuvor auf der Innenseite der Doppelzettel aufgebrachten Beleimung, so daß diese Doppelzettel von dem auf dem Aufbringefalzzangenzylinder gehalterten Schlauchstück mitgenommen werden. Bei dem weiteren Umlauf des Aufbringefalzzangenzylinders läuft das Zettel-Schlauchstückpaket an dem Leimwerk 11 vorbei, durch das dieses formatmäßig mit einem Leimauftrag versehen wird. Das so vorbereitete und beleimte Zettel-Schlauchstück-Paket wird anschließend auf den noch offenen Boden 12 eines Sackes durch den Aufbringefalzzangenzylinder 9 aufgedrückt.When the intermediate cylinder 7 rotates further, the fold bar arranged upstream of the needle row comes into contact with the folding pliers attached to the applicator plier cylinder 9, so that the leading end of a tubular web 10 is held by the folding pliers and thereby a piece of hose is torn off along a transverse perforation line. The feeding of the tubular web 10 is described in more detail below. This piece of tubing is then glued to the glue previously applied to the inside of the double label, so that these double labels are carried along by the tube piece held on the applicator cylinder. During the further circulation of the application folding pliers cylinder, the piece of piece of hose and tube runs past the glue unit 11, by means of which this is provided with a glue application in terms of format. The so prepared and glued slip piece of tube package is then pressed onto the still open bottom 12 of a sack by the application folder cylinder 9.

Anschließend wird der Boden in bekannter Weise zugelegt, so daß sich aus den Doppelzetteln ein doppellagiger Ventilschlauch bildet, in den zusätzlich ein weiteres von der Schlauchbahn 10 abgerissenes Schlauchstück eingelegt ist.The bottom is then increased in a known manner, so that a double-layer valve tube is formed from the double sheets, in which a further piece of tube torn off from the tube sheet 10 is inserted.

Die Schlauchbahn 10 wird zunächst als Flachbahn 14 von einer nicht dargestellten Vorratsrolle abgezogen. Sie wird dann über die Rollen 15,16 und 17 einer Schlauchbildeeinrichtung 18 zugeführt, in der die Flachbahn zu einer Schlauchbahn 10 zusammengelegt wird. Der so gebildete Schlauch 10 kann die Breite des späteren Bodens aufweisen. Er kann aber auch wesentlich schmaler ausgebildet sein.The tubular web 10 is first drawn off as a flat web 14 from a supply roll, not shown. It is then fed via the rollers 15, 16 and 17 to a tube forming device 18, in which the flat web is folded into a tube web 10. The hose 10 formed in this way can have the width of the subsequent base. But it can also be much narrower be trained.

Weiterhin besteht die Möglichkeit, die Schlauchbahn 10 im flachgelegten Zustand breiter als den fertigen Boden auszubilden, so daß durch Zulegen des Bodens die Ränder der Schlauchbahn beidseits zur Verstärkung mitumgefaltet und umgelegt werden.Furthermore, there is the possibility of making the tubular web 10 wider than the finished floor in the flat state, so that the edges of the tubular web are folded over and folded over on both sides for reinforcement by adding the floor.

Der Vorzug der Schlauchbahn 10 erfolgt durch ein Vorzugswalzenpaar 19 und 20, wobei die Bahn durch die Einrichtung 21 zwischen den beiden Vorzugswalzenpaaren 19 und 20 durch die Perforiereinrichtung 21 mit Querperforationen versehen wird.The tubular web 10 is preferred by a pair of preferred rollers 19 and 20, the web being provided with transverse perforations by the device 21 between the two pairs of preferred rollers 19 and 20 by the perforating device 21.

Mit der vorstehend beschriebenen Vorrichtung ist es auch möglich, die Bahn 14 als einlagige oder doppellagige Bahn auszubilden und auf die Schlauchbildestation 18 zu verzichten, so daß ein zusätzlicher Zettel auf den von dem Zwischenzylinder 7 transportierten Zettel oder Doppelzettel aufgebracht wird. Die Bahn 1 kann auch als Vliesbahn ausgebildet sein, so daß nach der Bodenbildung ein von einer Vliesbahn umgebenes Einfüllventil durch Zulegen des Bodens gebildet wird.With the device described above, it is also possible to design the web 14 as a single-layer or double-layer web and to dispense with the tube-forming station 18, so that an additional slip is applied to the slip or double slip transported by the intermediate cylinder 7. The web 1 can also be designed as a nonwoven web, so that after the bottom has been formed, a filling valve surrounded by a nonwoven web is formed by covering the bottom.

Im Bedarfsfalle kann auf die Umlenkwalzen 5 zum Versatz einer doppellagigen Bahn verzichtet werden.If necessary, the deflection rollers 5 to offset a double-layer web can be dispensed with.
