Description

Die Erfindung betrifft eine Vorrichtung zum Ausrichten einer Wicketer-Stapelstation in bezug auf die Kante einer Kunststoffschlauch- oder -halbschlauchbahn, bei der die Wicketer-Stapelstation aus einem längsverschieblichen Wicketergestell mit um eine Welle rotierenden Transportarmen zur Übernahme von von der Kunststoffschlauch- oder -halbschlauchbahn abgeschweißten Beuteln, einem auf einem Grundrahmen längsverschieblichen Endgestell, welches über einen Träger mit dem Wicketergestell verbunden ist, und einer zwischen dem Wicketergestell und dem Endgestell verlaufenden durch einen Endlosförderer gebildeten Stapelstrecke besteht, die intermittierend angetriebene Zugmittel mit Stapelstiftpaaren aufweist, auf welche die mit eingestanzten Positionierlöchern versehenen Beutel aufgenadelt werden, wobei die Vorrichtung eine Stelleinrichtung zum Querverschieben der Wicketer-Stapelstation entsprechend einer gemessenen Kantenabweichung aufweist und das Wicketergestell mit mindestens einer auf Rollen oder Gleitflächen eines Tragrahmens abgestützten Querschiene versehen ist.The invention relates to a device for aligning a Wicketer stacking station with respect to the edge of a plastic tube or semi-tubular web, in which the Wicketer stacking station consists of a longitudinally displaceable winder frame with transport arms rotating about a shaft for taking over welded welded from the plastic tube or semi-tubular web Bags, a longitudinally displaceable end frame on a base frame, which is connected to the winder frame via a carrier, and a stacking section running between the winder frame and the end frame and formed by an endless conveyor, which has intermittently driven traction means with pairs of stacking pins, onto which those provided with stamped-in positioning holes Bags are needled, the device having an adjusting device for moving the Wicketer stacking station according to a measured edge deviation and the wicking frame with at least one cross rail supported on rollers or sliding surfaces of a supporting frame.

Sogenannte Wicketer-Stapelstationen werden üblicherweise hinter Kunststoffbeutel von Kunststoffschlauch- oder halbschlauchbahnen durch Querschweißtrennähte abschweißenden Schweißstationen derart angeordnet, daß diese mit ihren paarweise angeordneten und mit Saugern oder Greifeinrichtungen versehenen Transportarmen die Beutel übernehmen und nach Drehung um 180° zum Zwecke ihrer Stapelung auf Stapelstiftpaare eines Endlosförderers einer Stapelstrecke aufnadeln. Um die einzelnen Beutel zu ihrer Stapelung aufnadeln zu können, sind diese mit entsprechenden Positionierlöchern versehen, die bereits vor der Schweißstation in die noch zusammenhängende Bahn eingestanzt werden. Beim Stapeln kann es dadurch zu Störungen kommen, daß die Bahn relativ zu der Wicketer-Stapelstation aus ihrer Richtung verläuft, so daß die einzelnen abgeschweißten Beutel von den Transportarmen nicht mehr lagerichtig übernommen werden und die Positionierlöcher nicht die aufragenden Stapelstiftpaare treffen, so daß die Beutel nicht mehr beim Stapeln von den Transportarmen abgenommen werden.So-called Wicketer stacking stations are usually placed behind plastic bags of plastic tubular or semi-tubular webs arranged by means of transverse welding separating welding stations arranged in such a way that these, with their transport arms arranged in pairs and equipped with suction devices or gripping devices, take over the bags and, after rotation by 180 °, stack them onto pairs of stacking pins of an endless conveyor of a stacking section. In order to be able to needle the individual bags for their stacking, they are provided with corresponding positioning holes which are punched into the still connected web before the welding station. When stacking, there may be malfunctions in that the web runs in its direction relative to the Wicketer stacking station, so that the individual welded bags are no longer taken over in the correct position by the transport arms and the positioning holes do not hit the upstanding stacking pin pairs, so that the bags can no longer be removed from the transport arms when stacking.

Die Funktionsweise einer Wicketer-Stapelstation ist beispielsweise aus der GB-A-2 094 765 bekannt. Eine Ausrichtung der Wicketer-Stapelstation auf die Bahnkante bei Bahnverzug ist hier jedoch nicht vorbeschrieben.The operation of a Wicketer stacking station is known for example from GB-A-2 094 765. Alignment of the Wicketer stacking station with the web edge in the event of web delay is not described here, however.

Aus der US-A-4 371 365 ist es bekannt, daß eine mit Stapelstiften versehene Stapelstrecke an die Stapellöcher von auf diese Stapelstifte aufgenadelten Beuteln angepaßt wird. Hier ist eine besondere Ausgestaltung der Stapelstation und der Stapelstrecke vorbeschrieben, die nicht unter Einsatz eines Wicketers arbeitet.From US-A-4 371 365 it is known that a stacking section provided with stacking pins is adapted to the stacking holes of bags needled onto these stacking pins. Here, a special configuration of the stacking station and the stacking section is described, which does not work using a winder.

Aus der DE-A-24 28 113 ist es bekannt, ein Gestell mit einer Wickelwalze zum Aufwickeln einer Warenbahn querverschieblich zur Längsausrichtung der Warenbahn zu verschieben, um ein kantengerades Aufwickeln dieser Warenbahn zu ermöglichen.From DE-A-24 28 113 it is known to move a frame with a winding roller for winding up a web so as to be displaceable transversely to the longitudinal alignment of the web in order to enable this web to be wound up in a straight line.

Gemäß dieser Schrift ist das Gestell einer Wickelwalze zum Aufwickeln einer Warenbahn schwenkbar auf einer Zwischenplatte gelagert, die auf einer Grundplatte querverschieblich geführt ist, wobei das Gestell mit einem Schwenkantrieb und die Zwischenplatte mit einem Antrieb zum Querverschieben versehen sind, die über eine Kante der Warenbahn abtastende Fühler derart gesteuert sind, daß die Warenbahn kantengerade auf den Wickel aufläuft.According to this document, the frame of a winding roller for winding a web is pivotally mounted on an intermediate plate which is guided on a base plate so that it can be moved, the frame being provided with a pivoting drive and the intermediate plate being provided with a drive for transverse displacement which scans over an edge of the web Sensors are controlled in such a way that the web runs straight on the winding.

Bei einer vorbenutzten Wicketer-Stapelstation der eingangs beschriebenen Art ist es zur lagerichtigen Übergabe der abgeschweißten Beutel durch die Transportarme des Wicketers auf die Stapelstiftpaare bekannt, die gesamte Wicketer-Stapelstation einschließlich des Wicketergestells, des Endgestells und der Stapelstrecke um den Betrag des gemessenen Versatzes der Bahn in Querrichtung zu verschieben, so daß die Positionierlöcher der Beutel die Stapelstiftpaare treffen. Das Querverschieben der gesamten Wicketer-Stapelstation einschließlich der Stapelstrecke ist jedoch verhältnismäßig aufwendig und wegen der großen zu bewegenden Massen schwerfällig.In a previously used Wicketer stacking station of the type described at the outset, it is known for the correct transfer of the welded bags through the transport arms of the wicketer to the stacking pin pairs, the entire Wicketer stacking station including the wicket frame, the end frame and the stacking distance by the amount of the measured offset of the web to move in the transverse direction so that the positioning holes of the bags meet the stacking pin pairs. Moving the entire Wicketer stacking station, including the stacking section, is relatively complex and cumbersome because of the large masses to be moved.

Aufgabe der Erfindung ist es daher, eine einfachere und feinfühligere Anpassung der Wicketer-Stapelstation mit Stapelstrecke an einen Versatz der Bahn zu ermöglichen.The object of the invention is therefore to enable a simpler and more sensitive adaptation of the Wicketer stacking station with a stacking section to an offset of the web.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der eingangs angegebenen Art dadurch gelöst, daß die Stelleinrichtung ausschließlich an dem Wicketergestell angreift, daß das Endgestell auf längsverlaufenden Schienen seines Grundrahmens durch Laufrollen derart abgestützt ist, daß es um kleine Winkel auf dem Grundrahmen drehbar ist, daß der das Wicketergestell mit dem Endgestell verbindende Träger biegesteif ausgeführt ist und daß das Wicketergestell mit dem Endgestell zusätzlich durch einen Mittelträger der Stapelstrecke verbunden ist. Die erfindungsgemäße Vorrichtung ermöglicht eine schnelle und feinfühlige Anpassung der Wicketer-Stapelstation einschließlich der Stapelstrecke an einen Versatz der Bahn durch Verlaufen, da lediglich das Wicketergestell um den Betrag des Versatzes querverschoben wird. Dabei führt das Wicketergestell eine leichte Drehung um eine vertikale Achse, die sich im Bereich des Endgestells befindet, aus, so daß nur durch Querverschiebung des Wicketergestells die gewünschte Anpassung an den Bahnversatz erreicht wird.According to the invention this object is achieved in a device of the type mentioned above in that the actuating device only acts on the wicket frame, that the end frame is supported on longitudinal rails of its base frame by rollers so that it can be rotated through small angles on the base frame so that the the winder frame with the end frame connecting carrier is designed to be rigid and that the winder frame is additionally connected to the end frame by a central girder of the stacking section. The device according to the invention enables Fast and sensitive adjustment of the Wicketer stacking station including the stacking section to an offset of the web by running, since only the wicket frame is shifted by the amount of the offset. The winder frame makes a slight rotation about a vertical axis, which is located in the area of the end frame, so that the desired adaptation to the web offset is achieved only by transverse displacement of the winder frame.

Die Querverschiebung kann durch Druckmittel-Kolben-Zylindereinheiten erfolgen. Zweckmäßigerweise ist zur Querverschiebung jedoch die Querschiene mit einer Zahnstange versehen, mit der ein von einem Schrittmotor oder dergleichen angetriebenes Ritzel kämmt, dessen Welle auf dem Tragrahmen gelagert ist.The transverse displacement can take place by means of pressure-piston-cylinder units. For transverse displacement, however, the transverse rail is expediently provided with a toothed rack with which a pinion driven by a stepping motor or the like meshes, the shaft of which is mounted on the support frame.

Der Tragrahmen der Wicketergestells kann mit Rollen oder Rädern versehen sein, die auf zur Stapelstrecke parallelen Schienen eines Grundrahmens geführt sind. Das Endgestell ist auf längsverlaufenden Schienen seines Grundrahmens durch Laufrollen abgestützt, so daß die Wicketer-Stapelstation und die Stapelstrecke leicht zu Reparatur- und Wartungszwecken in Längsrichtung verschoben werden können. Während des Betriebes sind das Wicketer- und das Endgestell jedoch relativ zu dem Grundrahmen verriegelt.The support frame of the winder frame can be provided with rollers or wheels which are guided on rails of a base frame parallel to the stacking section. The end frame is supported on longitudinal rails of its base frame by rollers, so that the Wicketer stacking station and the stacking section can easily be moved in the longitudinal direction for repair and maintenance purposes. During operation, however, the wicketer and end frames are locked relative to the base frame.

In den Seitenteilen 1, 2 des Wicketergestells 3 ist eine mit einem nicht dargestellten Antrieb versehene Welle 4 gelagert, die die paarweise angeordneten und mit Saugern oder Greifeinrichtungen versehenen Transportarme 5 trägt. Vor dem Wicketergestell 3 ist die Querschweißtrenneinrichtung 6 angeordnet. Diese besteht aus dem intermittierend angetriebenen Transportwalzenpaar 7 zum Vorschub der Kunststoffschlauch- oder -halbschlauchbahn 10 um jeweils eine Beutelbreite oder -länge. Das Schweißwerkzeug besteht aus einem oberen mit einer Schneide versehenen heb- und absenkbaren Schweißbalken 8 und einer unteren Schweißrolle 9, die den Gegenbacken bildet. Zum Abtasten einer Seitenkante der Bahn ist vor den Transportwalzen 7 die Fühleinrichtung 11 angeordnet. Vor der Fühleinrichtung ist eine Stanzeinrichtung angeordnet, die in den Rand der Bahn im vorgesehenen Abstand von der Seitenkante die Positionierlöcher einstanzt, deren Abstand dem Abstand der Stapelstiftpaare 12, 13 entspricht.In the side parts 1, 2 of the winder frame 3, a shaft 4, which is provided with a drive (not shown), is mounted carries the transport arms 5 arranged in pairs and provided with suction devices or gripping devices. The cross welding separating device 6 is arranged in front of the winder frame 3. This consists of the intermittently driven pair of transport rollers 7 for advancing the plastic tube or half tube web 10 by one bag width or length. The welding tool consists of an upper, with a cutting edge, lifting and lowering welding bar 8 and a lower welding roller 9, which forms the counter jaws. The sensing device 11 is arranged in front of the transport rollers 7 for scanning a side edge of the web. A punching device is arranged in front of the sensing device and punches the positioning holes in the edge of the web at the intended distance from the side edge, the distance of which corresponds to the distance between the stacking pin pairs 12, 13.

Die Stapelstiftpaare 12, 13 sind auf Platten einer endlosen Förderkette oder eines Zahnriemens 14 angeordnet, die über das vordere Umlenkrad 15, das im Wicketergestell 3 gelagert ist, und das hintere Umlenkrad 16, das im Endgestell 17 gelagert ist, umlaufen.The stacking pin pairs 12, 13 are arranged on plates of an endless conveyor chain or a toothed belt 14, which rotate over the front deflection wheel 15, which is mounted in the winder frame 3, and the rear deflection wheel 16, which is supported in the end frame 17.

Das Wicketergestell 3 ist mit dem Endgestell 17 durch einen längsverlaufenden biegesteifen Träger 18 verbunden. Weiterhin ist ein Mittelträger 19 der Stapelstrecke sowohl mit dem Wicketergestell 3 als auch mit dem Endgestell 17 verbunden, so daß eine weitere aussteifende Verbindung zwischen beiden Gestellen geschaffen ist.The wicket frame 3 is connected to the end frame 17 by a longitudinally rigid support 18. Furthermore, a center girder 19 of the stacking section is connected both to the winder frame 3 and to the end frame 17, so that a further stiffening connection is created between the two frames.

Die unteren Kanten der die Seitenteile 1, 2 des Wicketergestells 3 verbindenden Querträger 20, 21 bilden Querschienen, die auf den zylindrischen Mänteln von Rollen 23 abgestützt sind, die an Querholmen eines Tragrahmens 22 um waagerechte und zu der Stapelstrecke parallele Achsen drehbar gelagert sind. In dem Tragrahmen 22 ist ein über ein Getriebe 24 von einem Schrittmotor angetriebenes Ritzel 25 gelagert, das mit einer Zahnstange 26 kämmt, die in einem Fenster des Querträgers 20 parallel zu dessen Unterkante angeordnet ist.The lower edges of the cross members 20, 21 connecting the side parts 1, 2 of the winder frame 3 form cross rails which are supported on the cylindrical shells of rollers 23 which are rotatably mounted on cross bars of a support frame 22 about horizontal axes parallel to the stacking section. In the support frame 22 is a via a gear 24 from a stepper motor Driven pinion 25 mounted, which meshes with a rack 26 which is arranged in a window of the cross member 20 parallel to the lower edge.

Der Tragrahmen 22 ist weiterhin mit Laufrollen 27 versehen, die um Querachsen drehbar gelagert sind und auf parallel zur Stapelstrecke verlaufenden Schienen 28 eines Grundrahmens 29 geführt sind.The support frame 22 is further provided with rollers 27 which are rotatably mounted about transverse axes and are guided on rails 28 of a base frame 29 running parallel to the stacking section.

Das Endgestell 17 ist mit vier um Querachsen gelagerte Laufrollen 30 versehen, die auf parallel zur Stapelstrecke verlaufender Schienen 31 seines Grundrahmens 32 geführt sind.The end frame 17 is provided with four rollers 30 mounted about transverse axes, which are guided on rails 31 of its base frame 32 running parallel to the stacking section.

Das in dem Endgestell 17 gelagerte Umlenkrad 16 ist mit einem intermittierenden Antrieb 33 für das mit den Stapelstiften 12, 13 versehene Stapelband versehen.The deflection wheel 16 mounted in the end frame 17 is provided with an intermittent drive 33 for the stacking belt provided with the stacking pins 12, 13.

Sobald die Fühler 11 einen Querversatz der Bahn 10 messen, wird entsprechend dieses Versatzes über eine nicht dargestellte Steuereinrichtung der Schrittmotor eingeschaltet, so daß das Wicketergestell 3 über das Ritzel 25 über den gemessenen Versatz nachgestellt wird.As soon as the sensors 11 measure a transverse offset of the web 10, the stepping motor is switched on in accordance with this offset via a control device, not shown, so that the winder frame 3 is adjusted via the pinion 25 via the measured offset.

Entsprechend dem gemessenen Versatz wird durch eine ebenfalls nicht dargestellte Einrichtung auch die Stanzeinrichtung zum Stanzen der Positionierlöcher nachgestellt, so daß der Abstand der Positionierlöcher zur Kante der Bahn 10 gleich bleibt.Corresponding to the measured offset, the punching device for punching the positioning holes is also adjusted by a device, also not shown, so that the distance between the positioning holes and the edge of the web 10 remains the same.

Bei einer Querverschiebung des Wicketergestells 3 führt dieses mit der Stapelstrecke eine leichte Drehung um das Endgestell 17, das geringfügig mitverdreht wird, aus. Diese Drehung des Endgestells vermag dieses über seine auf den Schienen des Grundgestells 32 abgestützten Laufrollen 30 mitzumachen.In the event of a transverse displacement of the winder frame 3, it makes a slight rotation with the stacking section about the end frame 17, which is also rotated slightly. This rotation of the end frame is able to do this via its rollers 30 supported on the rails of the base frame 32.
