Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen eines mehrlagigen Schlauches aus in gleichen Abständen mit Querperforationen versehenen Papierbahnen, von dem zur Sackherstellung Schlauchabschnitte abgerissen werden,

  • mit mindestens einem im Maschinengestell gelagerten, an einer rotierenden Welle befestigten Perforiermesser, das die Papierbahnen mit Querperforationen versieht und dessen radialer Abstand zu der Welle zur Formateinstellung veränderbar ist,

  • mit einer die seitlich versetzt zueinander liegenden Ränder der über Leitrollen zusammengeführten Papierbahnen vor ihrer Faltung zu einem Schlauch mit einem die Längsklebenaht bildenden Klebstoffauftrag versehenden Längskleberolle.
  • The invention relates to a device for producing a multi-layer hose from paper webs provided at equal intervals with transverse perforations, from which hose sections are torn for sack production,
  • with at least one perforating knife mounted in the machine frame and fastened to a rotating shaft, which provides the paper webs with transverse perforations and whose radial distance from the shaft can be changed for setting the format,
  • with cross-gluing cylinders mounted in the machine frame, provided with cross-gluing strips and interacting with glue application devices, and
  • with one of the laterally offset edges of the paper webs brought together via guide rollers before they are folded into a tube with a longitudinal adhesive roller providing the longitudinal adhesive seam.
  • Papiersäcke, beispielsweise zur Verpackung von Zement oder anderen pulver- oder granulatförmigen Stoffen mit hoher Festigkeit, werden aus mehrlagigen Schlauchabschnitten hergestellt, deren einzelne Lagen bei der Schlauchbildung an ihren Rändern miteinander verklebt sind und an deren Enden die einzelnen Lagen mit fluchtend übereinander liegenden Schnittkanten (Glattschnitt) oder vorzugsweise einander nur teilweise überlappend in gestaffelter Formation liegen, so daß auch bei der Bodenbildung die einzelnen Lagen einzeln verklebt werden.Paper bags, for example for packaging cement or others powdery or granular substances with high strength, are made from multilayer hose sections, the individual layers of tubing along their edges are glued and at the ends of the individual layers cut edges aligned one above the other (smooth cut) or preferably only partially overlapping each other in staggered Formation lie, so that the bottom formation individual layers can be glued individually.

    Rationelle Maschinenausrüstungen machen es erforderlich, daß mit einer Anlage Schlauchabschnitte mit gestaffelter Anordnung der einzelnen Papierlagen unterschiedlicher Formate hergestellt werden können. Um diese gewünschte Formatvariabilität der sogenannten "Schlauchmaschinen" zu erreichen, müssen sich die die Schlauchabschnittlängen bestimmenden Abstände der Querperforationen in den einzelnen Papierlagen verändern und auch die Abstände der quer verlaufenden Querklebestreifen entsprechend anpassen lassen.Rational machine equipment requires that with a system of hose sections with a staggered arrangement of individual layers of paper of different formats can be produced can. To achieve this desired format variability of the so-called To reach "hose machines", they have to Distances of the cross perforations determining the length of the tube section change in the individual layers of paper and also the distances Adjust the transverse adhesive strips accordingly to let.

    Während es unschädlich ist, wenn zwischen der Umfangsgeschwindigkeit der Querklebeleisten und der Laufgeschwindigkeit der Papierbahnen gewisse Unterschiede bestehen, so daß es aufgrund der Relativgeschwindigkeit zu einem gewissen Verschmieren der Klebstoffaufträge kommt, können derartige Unterschiede der Umfangsgeschwindigkeit der Perforiermesser und der Papierbahnen nicht in Kauf genommen werden, weil hier Relativgeschwindigkeiten zu einem Ausreißen der Querperforationen und damit zu einem Abriß der Papierbahn führen können.While it is harmless if between the peripheral speed the cross adhesive strips and the running speed of the paper webs certain differences exist so that it is due to the relative speed some smearing of the adhesive application comes, such differences in peripheral speed the perforating knife and the paper webs not be accepted because here relative speeds increase a tearing out of the transverse perforations and thus to a tear the paper web can lead.

    Um Papierbahnen in Schlauchmaschinen in einem veränderlichen Abstand mit Querperforationen versehen zu können, ist es bekannt, die rotierenden Perforiermesser über Ungleichförmigkeitsgetriebe in der Weise anzutreiben, daß die Papierbahn in dem Bereich, in dem sich das Perforiermesser nicht im Eingriff mit der Papierbahn befindet, mit einer von der Umfangsgeschwindigkeit des Perforiermessers abweichenden Geschwindigkeit vorgezogen wird, während die Umfangsgeschwindigkeit des Perforiermessers im Zeitpunkt des Eingriffes mit der Papierbahn mit deren Laufgeschwindigkeit im wesentlichen gleich ist. Derartige Ungleichförmigkeitsgetriebe bestehen aus Kurbelschleifengetrieben, die wegen ihrer Ungleichförmigkeit großen Beschleunigungen und Verzögerungen bei ihrem Umlauf unterliegen, so daß wegen der dadurch entstehenden Massenkräfte die Maschine nur mit einer geringeren Leistung laufen kann, um die entstehenden Massenkräfte innerhalb zulässiger Grenzen zu halten.To paper webs in tube machines at a variable distance to be able to provide cross perforations, it is known the rotating perforating knives via non-uniform gears in such a way that the paper web in the area in which the perforating knife does not engage with the paper web is located, with one of the peripheral speed of the perforating knife different speed is preferred while the circumferential speed of the perforating knife at the time the engagement with the paper web at its running speed is essentially the same. Such non-uniformity gears consist of crank loop gearboxes because of their irregularities, great accelerations and decelerations subject to their circulation, so that because of the resulting Inertial forces the machine only with a lower output can run to the emerging mass forces within to keep permissible limits.

    Aus der US-PS 2,013,086 ist eine Schlauchmaschine der eingangs angegebenen Art bekannt, bei der die die Querperforationen anbringenden Perforiermesser an Armen befestigt sind, die in radialer Richtung zu den diese tragenden Wellen verstellbar sind. Diese in radialer Richtung verstellbaren Perforiermesser lassen sich durch entsprechende Änderung auch der Achsabstände der die Perforiermesser tragenden Wellen mit ständig gleicher Umfangsgeschwindigkeit wie der Laufgeschwindigkeit der Papierbahnen antreiben, so daß keine Ungleichförmigkeiten in dem Antrieb vorhanden sind, die aufgrund von Massenkräften die Laufgeschwindigkeit der Schlauchmaschine begrenzen könnten. Der Einstellung der Formate sind jedoch der bekannten Maschine dadurch Grenzen gesetzt, daß bei einer Verringerung der Abstände der Querperforationen die die Perforationsmesser tragenden Arme nur so weit radial nach innen verstellt werden können, daß deren die Wellen überragenden, rückwärtigen Enden nicht an die Papierbahn anstoßen und diese beschädigen. Die bekannte Schlauchmaschine erlaubt daher eine Formatvariabilität nur in einem Umfang, bei dem die größten Abschnittlängen etwa doppelt so groß sind wie die kleinsten, weil bei einer weiteren Verringerung der Abständen die nicht mit einem Perforierwerkzeug besetzten Enden der Arme in den Weg der durchlaufenden Papierbahnen geraten würden. Die bekannte Schlauchmaschine genügt daher den heutigen Anforderungen an die Formatvariabilität nicht, da es gefordert wird, Schlauchabschnitte herzustellen, deren kleinste Längen etwa einem Sechstel bis einem Achtel der größten Längen entsprechen.From the US-PS 2,013,086 is a hose machine of the beginning specified type known, in which the cross perforations attaching Perforating knives are attached to arms in radial Direction to which these supporting shafts are adjustable. This Leave perforating knife adjustable in the radial direction by changing the center distances of the Perforating knife-carrying shafts with constant circumferential speed like driving the running speed of the paper webs so that there are no irregularities in the drive are the walking speed due to mass forces limit the hose machine. The setting of the formats however, there are limits to the known machine, that with a decrease in the spacing of the cross perforations the arms carrying the perforation knives only so far radially can be adjusted inwards so that their waves, Do not bump the rear ends against the paper web and damage them. The known hose machine therefore allows format variability only to the extent that the largest section lengths are about twice as large as the smallest, because with a further reduction in the distances ends of the arms not studded with a perforating tool would get in the way of the continuous paper webs. The well-known The hose machine therefore meets today's requirements not to the format variability, since hose sections are required produce, the smallest lengths of about a sixth correspond to one eighth of the greatest lengths.

    Aufgabe der Erfindung ist es daher, eine Schlauchmaschine der eingangs angegebenen Art zu schaffen, auf der sich bei hoher Leistung und einfacher Umrüstung Schlauchabschnitte herstellen lassen, deren Längen in einem großen Bereich variiert werden können.The object of the invention is therefore a hose machine to create the type specified at the beginning, at high performance and easy retrofitting to produce hose sections, whose lengths can be varied over a wide range.

    Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß an der Welle in gleichen Winkelabständen vier Träger für wahlweise an diesen befestigbare Perforiermesser angeordnet sind, die Einrichtungen zur Verstellung ihres radialen Abstandes von der Welle besitzen. Bei der erfindungsgemäßen Schlauchmaschine läßt sich der größte Abstand der Querperforationen in den Papierbahnen dadurch einstellen, daß die Träger auf ihren größten radialen Abstand von der diese tragenden Welle ausgefahren und nur an einem Träger ein Perforiermesser befestigt wird. Soll der kleinstmögliche Abstand der Querperforationen eingestellt werden, werden die vier Träger nach innen auf ihren geringsten radialen Abstand zur Welle eingestellt und sämtliche vier Träger mit Perforiermessern besetzt. In einer mittleren Einstellung der Träger lassen sich an einander gegenüberliegenden Trägern Perforiermesser befestigen. Zwischen dem kleinsten und dem größten einstellbaren Abstand der Querperforationen lassen sich sämtliche Formate durch entsprechendes Aus- und Einfahren der Träger und/oder Anordnung von einem, zwei oder vier Perforiermessern an den Trägern einstellen. Da also bei der erfindungsgemäßen Schlauchmaschine auf Ungleichförmigkeitsantriebe verzichtet worden ist und sich die Laufgeschwindigkeit der Papierbahnen jeweils an die Umfangsgeschwindigkeit der Perforiermesser anpassen läßt, kann die erfindungsgemäße Vorrichtung mit einer Formatvariabilität in weiten Grenzen mit hoher Leistung betrieben werden.According to the invention, this object is achieved in a device of the generic type Kind solved in that on the shaft in the same Angular distances four supports for attachable to these Perforating knives are arranged, the devices for adjustment have their radial distance from the shaft. In the Hose machine according to the invention can be the greatest distance adjust the cross perforations in the paper webs, that the carrier is at its greatest radial distance from this carrying shaft extended and only one perforating knife on one carrier is attached. Should the smallest possible distance of the Cross perforations are set, the four straps adjusted inwards to their smallest radial distance to the shaft and all four straps are set with perforating knives. In a medium setting the straps can be attached to each other Fasten perforating knife on opposite supports. Between the smallest and the largest adjustable distance of the All formats can be cross-perforated by appropriate Extension and retraction of the carrier and / or arrangement of adjust one, two or four perforating knives on the straps. So since in the tube machine according to the invention on non-uniformity drives has been waived and the Running speed of the paper webs to the peripheral speed the perforating knife can be adjusted, the invention Device with a wide format variability Limits are operated with high performance.

    Vorstehend ist eine Ausführungsform der Erfindung beschrieben worden, bei der die einzelnen durch die Papierbahnen gebildeten Lagen bereits vor ihrer Querperforation zu einem Schlauch gebildet worden sind, da von dem Schlauch Schlauchabschnitte abgetrennt werden sollen, die an ihren Enden fluchtend übereinander liegende Schnittkanten aufweisen. Um von dem mehrlagigen Schlauch mit glatten Schnitten versehene Schlauchabschnitte abreißen zu können, müssen die Perforationen der einzelnen Lagen genau übereinander liegen, so daß nur ein einziges Perforiermesser vorgesehen ist, das sämtliche bereits zu einem Schlauch zusammengelegte Lagen durchgehend perforiert.An embodiment of the invention is described above in which the individual formed by the paper webs Layers were already formed into a tube before their transverse perforation have been cut off from the hose hose sections are supposed to be aligned at their ends one above the other have horizontal cut edges. To get from the multilayer Tear off hose sections with smooth cuts To be able to, the perforations of the individual layers lie exactly one above the other so that only a single perforating knife it is provided that all of them are already folded into a tube Layers perforated throughout.

    Mit besonderem Vorteil läßt sich die Erfindung aber bei Vorrichtungen zur Herstellung sogenannter Staffelsäcke verwirklichen, bei denen die einzelnen Lagen des mehrlagigen Schlauchabschnittes zusätzlich auch in Längsrichtung einander nur teilweise überlappend liegen. Nach einer bevorzugten Ausführungsform der Erfindung ist daher vorgesehen, daß im Maschinengestell für jede der getrennt voneinander über Leitwalzen laufenden Papierbahnen mindestens ein an einer rotierenden Welle befestigtes Perforiermesser vorgesehen ist, das die Papierbahnen mit in Längsrichtung versetzt zueinander liegenden Querperforationen versieht, und daß an den Wellen in gleichen Winkelabständen 4 Träger für wahlweise an diesen befestigbare Perforiermesser angeordnet sind, die Einrichtungen zur Verstellung ihres radialen Abstandes von jeder Welle besitzen.However, the invention can be used with particular advantage in the case of devices for the manufacture of so-called season sacks, where the individual layers of the multi-layer hose section additionally also only partially overlapping one another in the longitudinal direction lie. According to a preferred embodiment of the invention it is therefore provided that in the machine frame for each of the paper webs running separately over guide rollers at least a perforating knife attached to a rotating shaft is provided that the paper webs in the longitudinal direction staggered transverse perforations, and that on the shafts at equal angular intervals 4 carriers for optional perforating knives that can be attached to them are arranged, the devices for adjusting their radial distance from own every wave.

    Obwohl bei Schlauchmaschinen ein gewisses Ausstreichen oder Verschmieren der aufgetragenen Querklebstoffstreifen in Kauf genommen werden kann, darf dieses Verschmieren aufgrund der Relativgeschwindigkeit der Papierbahnen und der Querklebeleisten ein zulässiges Maß nicht überschreiten. Nach einer erfinderischen Weiterbildung ist daher vorgesehen, daß die Querklebezylinder in gleichen Winkelabständen mit vier Aufnahmen für Querklebeleisten versehen sind, die in gleicher Anzahl wie die Perforiermesser angebracht werden. Durch geeignete Wahl des Durchmessers des Querklebezylinders läßt sich dadurch sicherstellen, daß entsprechend der Anzahl der zum Einsatz kommenden Perforiermesser eine gleiche Anzahl von Querklebeleisten vorgesehen wird, so daß ohne aufwendige Veränderung des Durchmessers des Querklebezylinders ein Ausstreichen der quer verlaufenden Klebstoffstreifen lediglich in einem geringen und in Kauf zu nehmenden Ausmaß erfolgt. Bei der Umrüstung der Schlauchmaschine auf ein anderes Format brauchen die Querklebezylinder lediglich mit einer der Anzahl der Perforiermesser entsprechenden Anzahl von Querklebeleisten versehen zu werden, was sich in einfacher Weise schnell bewirken läßt.Although some streaking or smearing in hose machines of the applied cross adhesive strips this smearing may occur due to the relative speed of the paper webs and the cross-adhesive strips is a permissible one Do not exceed dimension. After inventive training it is therefore provided that the cross-glue cylinder in equal angular distances with four holders for cross-adhesive strips are provided in the same number as the perforating knife be attached. By suitable choice of the diameter of the Cross-glue cylinder can be ensured by doing so one of the number of perforating knives used same number of cross-adhesive strips is provided, so that without complex change in the diameter of the cross-gluing cylinder spreading out the transverse adhesive strips only is carried out to a small and acceptable extent. When converting the tube machine to a different format the cross-glue cylinders only need one of the number the number of cross-adhesive strips corresponding to the perforating knife to be provided, which can be done quickly in a simple manner leaves.

    Zweckmäßigerweise entspricht der Abstand gegenüberliegender Aufnahmen des Querklebezylinders dem mittleren, einstellbaren Abstand gegenüberliegender Träger der Perforiermesser.Appropriately, the distance between opposite recordings corresponds of the cross-glue cylinder the mean, adjustable distance opposite carrier of the perforating knife.

    Um die von dem Schlauch abgerissenen Schlauchabschnitte störungsfrei durch das Anformen von Böden zu Säcken verarbeiten zu können, müssen die gestaffelt angeordneten Lagen an den Enden der Schlauchabschnitte frei von Klebstoffaufträgen sein. In weiterer Ausgestaltung der Erfindung ist daher vorgesehen, daß die Längskleberolle konstanten Durchmessers über ihren Unmfang mit vier wahlweise schließbaren Aussparungen versehen ist, die Klebstoffaufträge auf die mit Querperforationen versehenen Randbereiche der Papierbahn verhindern. Auch bei dieser Längskleberolle kann eine gewisse Relativgeschwindigkeit zwischen deren Umfang und der Papierbahn in Kauf genommen werden, solange sichergestellt ist, daß die Aussparungen mit jeweils die mit Querperforationen versehenen Randbereiche der Papierbahnen überbrücken.Around the hose sections torn off the hose without interference to be able to process them into sacks by molding the staggered layers at the ends of the Hose sections must be free of adhesive. In another Embodiment of the invention is therefore provided that the longitudinal adhesive roll constant diameter over its circumference with four optionally lockable recesses is provided, the adhesive applications on the edge areas with cross perforations prevent the paper web. This longitudinal adhesive roll can also a certain relative speed between their circumference and the paper web can be accepted as long as ensured is that the recesses are each with cross perforations bridge the edge areas of the paper webs.
