Abstract

1. Feed unit for a paper-bag and/or plastic-bag machine, comprising a separating apparatus (22, 27) arranged downstream, characterized in that it consists of an arrangement of guide members (6, 7, 8, 17) arranged on an inner arc, and of counter-pressure members (11, 12, 13, 14, 15, 16) arranged on the outside of the arc, which arrangement deflects the arriving bag (1) in the opposite direction in an arc.

Description

Die Erfindung betrifft eine Vorzugseinheit für eine Papier- und/oder Folienschlauchmaschine mit einer nach­geordneten Trennvorrichtung.The invention relates to a preferred unit for a paper and / or film tube machine with a downstream separating device.

Bei Papier- oder Folienschlauchmaschinen ist es üblich, die Vorzugseinheit entsprechend der gerad­linien Führung des Papier- oder Folienschlauchs gerad­linig auszubilden, d. h. die an der Warenbahn angreifen­den Transportelemente im wesentlichen in einer gerad­linigen Ebene anzuordnen. Eine solche Anordnung hat zur Folge, daß vergleichsweise hohe Anpreßkräfte über die Vorzugsorgane aufgebracht werden müssen. Das Auf­bringen hoher Anpreßkräfte über die Vorzugsorgane ist nicht nur erforderlich, um den Vorzug selbst sicher­zustellen, sondern auch deshalb, um im Falle einer Vorperforation und einer nachgeschalteten Abreißein­richtung ein Durchrutschen des transportierten Material­schlauchs durch die Vorzugseinheit mit allen daraus resultierenden negativen Folgen zu verhindern.In the case of paper or film tube machines, it is customary to design the preferred unit in a straight line in accordance with the straight line guidance of the paper or film tube, ie to arrange the transport elements engaging on the material web essentially in a straight plane. Such an arrangement has the consequence that comparatively high contact forces have to be applied via the preferred members. The application of high contact forces via the preferred elements is not only necessary to ensure the preference itself, but also to prevent the transported material hose from slipping through the preferred unit in the event of a pre-perforation and a subsequent tear-off device, with all the resulting negative consequences.

Als besonders nachteilig hat es sich dabei erwiesen, daß bei einem Durchrutschen des Materialschlauchs nicht nur im Bereich der Vorzugseinheit unprogrammge­mäß abgerissen wird, sondern daß eine Trennung der vorperforierten Materialbahnen sogar bis in den Schlauch­bildungsbereich und in den Bereich der Perforations­messer möglich ist.It has proven to be particularly disadvantageous that if the material hose slips through, not only is the program torn off in the area of the preferred unit, but that the pre-perforated material webs can even be separated into the area of the hose formation and into the area of the perforation knife.

Ausgehend von diesem Stand der Technik liegt der Er­findung die Aufgabe zugrunde, eine Vorzugseinheit der als bekannt vorausgesetzten Art so auszubilden, daß auch bei vergleichsweise geringen Andruckkräften der Mitnahmeorgane einerseits ein besonders schonender Vor­zug der Schlauchbahn möglich ist und daß andererseits auch durch den Ruck beim Abreißen vorperforierter Schlauchabschnitte eine Durchrutschen ausgeschlossen ist.Based on this prior art, the invention has for its object to design a preferred unit of the type presumed to be known so that a particularly gentle preference of the tubular web is possible on the one hand, even with comparatively low pressing forces of the entrainment members, and on the other hand, is perforated by the jerk when torn off Slipping through the hose sections is excluded.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß da­durch, daß die Vorzugseinheit aus einer den ankommenden Schlauch in einem Bogen in Gegenrichtungen umlenkenden Anordnung von auf einem Bogen innen angeordneten Führungsorganen und auf der Außenseite des Bogens und des Schlauchs angeordneten Gegendruckorganen besteht.This object is achieved according to the invention in that the preferred unit consists of an arrangement deflecting the incoming hose in a bend in opposite directions, of guide members arranged on the inside of a bend and counter-pressure members arranged on the outside of the bend and the hose.

Bei der erfindungsgemäßen Vorzugseinheit kann der An­preßdruck der Gegendruckorgane oder Mitnehmerorgane im Gegensatz zu eben ausgebildeten Vorzugseinheiten, bei denen Rollen oder Förderbänder im Vorzugsbereich stark aufeinander gepreßt werden müssen, relativ gering sein. Bereits durch die bogenförmige Umleitung des an­kommenden Schlauchs und das Straffhalten der zulaufenden Warenbahn durch Bahnspannungskontrollen wird eine sehr gute Friktion zwischen dem bogenförmig umgeleiteten Schlauch und den Gegendruckorganen sichergestellt. Dies hat zur Folge, daß mit der erfindungsgemäßen Vorzugs­einheit auch besonders empfindliche Materialsorten, wie beispielsweise stark dehnbare Papiere, einwand­frei verarbeitet werden können. Die erfindungsgemäße Vorrichtung läßt sich aber auch mit großem Vorteil bei der Verarbeitung unproblematischer Materialarten einsetzen.In the preferred unit according to the invention, the contact pressure of the counterpressure elements or driver elements can be relatively low, in contrast to the previously formed preferred units, in which rollers or conveyor belts in the preferred area must be pressed strongly against one another. Simply by redirecting the incoming hose and keeping the incoming hose taut Material tension through web tension controls ensures a very good friction between the curved tube and the counter pressure elements. The consequence of this is that the preferred unit according to the invention can also be used to process particularly sensitive types of material, such as, for example, highly stretchable paper. However, the device according to the invention can also be used with great advantage in the processing of unproblematic types of material.

Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben. Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung im einzelnen beschrieben. Es zeigen:

  • Figur 1 - eine schematische Seitenansicht der Vor­zugseinheit mit Abreißeinrichtung,
  • Figur 2 - eine Draufsicht auf die in Figur 1 darge­stellte Vorrichtung.
Preferred embodiments of the invention are described in the subclaims. A preferred embodiment of the invention is described in detail below with reference to the drawing. Show it:
  • FIG. 1 shows a schematic side view of the preferred unit with a tear-off device,
  • Figure 2 - a plan view of the device shown in Figure 1.

Ein Papierschlauch oder Folienschlauch 1 wird in einer Schlauchbildungsstation gebildet. Formbleche 3 dienen zur Bildung der Seitenfalten. Mit 4 ist die Lauf­richtung des Papier- oder Folienschlauchs bezeichnet.A paper tube or film tube 1 is formed in a tube forming station. Shaped sheets 3 are used to form the gussets. With 4 the direction of the paper or film tube is designated.

Der Schlauch läuft über eine Walze 5 und dann auf ein endloses Förderband 17.The hose runs over a roller 5 and then onto an endless conveyor belt 17.

Das endlose Förderband 17 kann in einzelne, nebenein­ander angeordnete Abschnitte unterteilt sein, die mit Abstand voneinander angeordnet sind. Das Förderband 17 läuft über eine Umlenkwalze 6 sowie zahlreiche auf der Innenseite eines Bogens angeordnete innere Walzen 8 sowie über eine weitere Umlenkwalze 7.The endless conveyor belt 17 can be divided into individual sections arranged next to one another, which are arranged at a distance from one another. The conveyor belt 17 runs over a deflection roller 6 and numerous inner rollers 8 arranged on the inside of a sheet and via a further deflecting roller 7.

An der Außenseite des Bogen ist ein äußeres Förder­band 16 angeordnet, das über Umlenkwalzen 9, 10 und 11 verläuft sowie über Gegendruckwalzen 12, 13, 14 und 15.An outer conveyor belt 16 is arranged on the outside of the sheet and runs over deflection rollers 9, 10 and 11 and over counter-pressure rollers 12, 13, 14 and 15.

Der Schlauch 1 wird nach dem Verlassen der bogen­förmigen Vorzugseinheit, welche von den beiden Förder­bändern 17 und 16, sowie den zugehörigen Walzen und Rollen gebildet wird, über ein Abreißorgan geführt. Der aus der Vorzugseinheit austretende Schlauch wird nicht geradlinig über die Abreißeinrichtung 22 ge­führt, sondern nach oben geneigt. Hierdurch wird das Abreißen mit Hilfe der Abreißstation 27 erleichtert. Die Abreißstation 27 besteht aus Förderbändern 24 und 25, die über Umlenkwalzen und Andruckrollen geführt werden.After leaving the arcuate preferred unit, which is formed by the two conveyor belts 17 and 16 and the associated rollers and rollers, the hose 1 is guided over a tear-off element. The hose emerging from the preferred unit is not guided in a straight line over the tear-off device 22, but is inclined upward. This makes tearing off easier with the help of tear-off station 27. The tear-off station 27 consists of conveyor belts 24 and 25 which are guided over deflection rollers and pressure rollers.

Die oberen inneren drei Walzen sind fest gelagert, während die unteren, auf Lücke angeordneten Walzen so­genannte Druckwalzen sind, die mit Hilfe eines Exzenters 26 zum Abreißen angehoben werden können. Die Förder­bänder 24 und 25 laufen mit Voreilung gegenüber den Förderbändern 16 und 17. Beim Anpressen der unteren Druckwalzen erfolgt das Abreißen an der Abreißeinrich­tung 22, die das Abreißen an der perforierten Stelle erleichtert.The upper inner three rollers are fixed, while the lower rollers arranged on a gap are so-called pressure rollers, which can be lifted off with the aid of an eccentric 26. The conveyor belts 24 and 25 run ahead of the conveyor belts 16 and 17.

Abreißstationen, wie sie bei 27 dargestellt sind, ge­hören zum Stand der Technik.Tear-off stations, as shown at 27, belong to the prior art.

Hinter der Abreißstation werden die getrennten Schlauchabschnitte in üblicher Weise zu weiteren Stationen gefördert.After the tear-off station, the separate hose sections are conveyed to further stations in the usual way.
