Abstract

A device for applying reinforcement patches provided with glue to a web provided with transverse perforations comprises a means for tearing off the sections connected to one another by the transverse- perforation lines. Provided above the deflection roller (4) on the inlet side of a band conveyor consisting of mutually spaced continuous conveyor belts is a supply roller (6) which presses the incoming web (3) against the deflection rollers (4). A roller (7) supporting the conveyor belts (5) of the upper side is mounted with a spacing behind the deflection rollers (4) on the inlet side, this spacing being smaller than the spacing between the transverse-perforation lines of the web. The supporting roller (7) forms the counter-pressure roller for a rotating segment (8) with cylindrical circumferential surface which transports and holds a reinforcement patch (14). The radius and the speed of the circumferential surface of the segment (8) are so matched to the section lengths of the web (3) that this surface rolls between in each case two conveyor belts over part of each section while the web (3) is pressed against the counter-pressure roller (7). In this arrangement, the circumferential speed of the segment (8) and of the counter-pressure roller (7) is greater than the conveying speed of the band conveyor, so that the section (16) is torn off from the web during gluing of the patch (14) to a section.

Description

Die Erfindung betrifft eine Vorrichtung zum Aufbringen von mit einem Leimauftrag versehenen Verstärkungszetteln auf eine mit Querperforationen versehen Bahn, vorzugsweise auf eine Bahn aus über die Querperforationen miteinander verbundenen Beuteln, mit einer Einrichtung zum Abreißen der durch die Querperforationen miteinander verbundenen Abschnitte oder Beutel von der Bahn.The invention relates to a device for applying reinforcement sheets provided with a glue application to a web provided with transverse perforations, preferably to a web of bags connected to one another via the transverse perforations, with a device for tearing off the sections or bags connected to one another by the transverse perforations from the web.

Kunststoffolienbeutel werden beispielsweise ausgehend von einer flach liegenden Schlauchbahn aus thermoplastischem Kunststoff dadurch hergestellt, daß die Schlauchbahn mit Querschweißnähten und neben diesen mit Querperforationslinien versehen wird, so daß sich die einzelnen Beutel von der Bahn längs der Querper­forationslinien abreißen lassen. Sollen aus den Beuteln Beutel­stapel gebildet werden, müssen die einzelnen Beutel maschinell abgerissen und gestapelt werden. Zusätzlich ist es häufig erforderlich, die Bahn bzw. die einzelnen Beutel mit Verstärkungszetteln zu bekleben, die beispielsweise Grifflochver­stärkungen oder Aufhängelaschen bilden können.Plastic film bags are made, for example, starting from a flat-lying tubular web made of thermoplastic material in that the tubular web is provided with cross-weld seams and next to these with transverse perforation lines, so that the individual bags can be torn off the web along the transverse perforation lines. If stacks of bags are to be formed from the bags, the individual bags must be torn off and stacked by machine. In addition, it is often necessary to glue reinforcement labels to the web or the individual bags, which can form grip hole reinforcements or hanging tabs, for example.

Um eine Vorrichtung der eingangs angegebenen Art zu verwirklichen, können schneller als die Bahn laufende Abreiß­walzen und die aufzuklebenden Zettel aufdrückende Segmente vorge­sehen werden. Eine derartige Vorrichtung wäre jedoch verhältnis­mäßig aufwendig.To a device of the type specified at the beginning Realize can be provided faster than the web running tear-off rollers and the segments to be glued on pieces of paper. However, such a device would be relatively expensive.

Aufgabe der Erfindung ist es daher, eine einfach aufgebaute und daher wirtschaftlich herstellbare Vorrichtung der eingangs angegebenen Art zu schaffen.The object of the invention is therefore to provide a simply constructed and therefore economically producible device of the type specified.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der gattungsgemäßen Art dadurch gelöst, daß oberhalb der einlauf­seitigen Umlenkrollen eines aus im Abstand voneinander angeordneten endlosen Förderriemen bestehenden Förderbandes eine die einlaufende Bahn gegen die Umlenkrollen andrückende Förderwalze angeordnet ist, daß eine die Förderriemen des Obertrums stützende Walze in einem Abstand hinter den einlauf­seitigen Umlenkwalzen gelagert ist, der kleiner ist als der Abstand der Querperforationslinien der Bahn voneinander, daß die stützende Walze die Gegendruckwalze für ein die Verstärkungs­zettel halterndes und transportierendes rotierendes Segment mit zylindrischer Umfangsfläche bildet, daß der Radius und die Umfangsgeschwindigkeit der Umfangsfläche des Segments derart auf die Abschnittlängen der Bahn abgestimmt sind, daß diese unter Andruck der Bahn gegen die Gegendruckwalze zwischen zwei Förder­riemen auf einem Teil eines jeden Abschnitts abrollt und daß die Umfangsgeschwindigkeit des Segments und der Gegendruckwalze größer ist als die Fördergeschwindigkeit des Förderbandes, so daß unter Aufkleben des Zettels auf einen Abschnitt dieser von der Bahn abgerissen wird.According to the invention, this object is achieved in a device of the generic type in that above the inlet-side deflection rollers of a conveyor belt consisting of spaced-apart endless conveyor belts, a conveyor roller pressing the incoming web against the deflection rollers is arranged in that a roller supporting the conveyor belts of the upper run is in one Distance is stored behind the inlet-side deflection rollers, which is smaller than the distance of the transverse perforation lines of the web from one another, that the supporting roller forms the counter-pressure roller for a rotating segment with a cylindrical peripheral surface that supports and transports the reinforcement labels, such that the radius and the peripheral speed of the peripheral surface of the segment are matched to the section lengths of the web in such a way that it rolls on a part of each section under pressure of the web against the counter-pressure roller between two conveyor belts d that the peripheral speed of the segment and the counter-pressure roller is greater than the conveying speed of the conveyor belt, so that when the piece of paper is stuck to a section it is torn off the web.

Bei der erfindungsgemäßen Vorrichtung übernimmt somit das rotierende Segment eine Doppelfunktion. Einmal drückt es den aufzuklebenden Zettel auf die mit diesen zu beklebenden abzureißenden Abschnitte der Bahn und zum anderen wirkt das Segment als intermittierend an der Bahn angreifendes Abreiß­element. Da zwischen den einlaufseitigen Umlenkrollen und der mit diesem zusammenwirkenden Förderwalze die mit Förderband­geschwindigkeit geförderte Bahn festgehalten wird, reißt das mit höherer Umfangsgeschwindigkeit rotierende und mit der Gegendruck­walze zusammenwirkende Segment die einzelnen Abschnitte längs den Querperforationslinien ab.In the device according to the invention, the rotating segment therefore performs a double function. On the one hand it presses the sticky note onto the sections of the web to be torn off and on the other hand it works Segment as an intermittent tear-off element on the web. Since the web conveyed at the conveyor belt speed is held between the inlet-side deflection rollers and the conveyor roller interacting with it, the segment rotating at a higher peripheral speed and interacting with the counter-pressure roller tears off the individual sections along the transverse perforation lines.

Um einen gleichmäßigen Abriß zu gewährleisten, können neben dem die Zettel aufklebenden Segment weitere Segmente vorgesehen sein, die jedoch nur Andruckfunktion haben.In order to ensure a uniform tear-off, other segments can be provided in addition to the segment which sticks the notes on, but these have only a pressure function.

Selbstverständlich können auch mehrere zettelaufklebende Segmente vorhanden sein.Of course, there can also be several sticky segments.

Zweckmäßigerweise ist das Segment zur Halterung der beleimten Zettel in seiner Umfangsfläche mit Saugluftöffnungen oder mindestens einem Saugluftkanal versehen. Die Saugluft kann den Saugluftdüsen oder Saugluftschlitzen in der Umfangsfläche in der üblicherweise durch sogenannte Drehdurchführungen zugeführt werden.The segment for holding the glued papers is expediently provided with suction air openings or at least one suction air duct in its peripheral surface. The suction air can be supplied to the suction air nozzles or suction air slots in the circumferential surface, usually by means of so-called rotary unions.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß im Bereich der nachlaufenden Kante der Umfangsfläche des Segments eine Messerschneide angeordnet ist, die mit einer rotierenden Gegenschneide zum Abtrennen der Zettel von einer zugeführten Zettelbahn zusammenwirkt.In a further embodiment of the invention it is provided that in the region of the trailing edge of the circumferential surface of the segment a knife edge is arranged which interacts with a rotating counter-edge for separating the notes from a supplied sheet of paper.

Häufig ist es erforderlich, daß die Zettel mit Griffloch­öffnungen oder Stapellöchern versehen sind. In weiterer Ausgestaltung der Erfindung ist daher vorgesehen, daß die Umfangsfläche des Segments mit einem mit gleicher Geschwindigkeit rotierenden Stempel einer Stanzeinrichtung zusammenwirkt.It is often necessary for the notes to be provided with grip hole openings or stack holes. In a further embodiment of the invention it is therefore provided that the peripheral surface of the segment interacts with a punch of a punching device rotating at the same speed.

Sollen die Zettel beispielsweise der Stapelung dienende Laschen bilden, können diese im Bereich des nachlaufenden Endes eines jeden Abschnitts in der Weise aufgedrückt werden, daß diese die durch den Abriß gebildete Kante überlappen.If, for example, the notes are to form tabs serving for stacking, they can be pressed on in the region of the trailing end of each section in such a way that they overlap the edge formed by the tear.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß an das Förderband ein mit seinem Untertrum fördernder Saugband­förderer anschließt, unterhalb von dem ein Stapelbandförderer angeordnet ist, auf dessen intermittierend fortgeschalteten Stapelstifte ein heb- und absenkbarer Stempel die Abschnitte in der Weise aufnadelt, daß die Stapelstifte die Zettel in den in diese eingestanzten Stapellöcher durchsetzen.In a further embodiment of the invention, it is provided that a suction belt conveyor conveying with its lower run connects to the conveyor belt, below which a stacking belt conveyor is arranged, on the intermittently advanced stacking pins of which a stamp which can be raised and lowered is needled into the sections in such a way that the stacking pins pin Insert the slip of paper into the punched holes.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur eine Vorrichtung zum Aufbringen vom Verstärkungszetteln auf von einer Bahn abzureißende Abschnitte in Seitenansicht schematisch dargestellt ist, näher erläutert.An embodiment of the invention is explained in more detail below with reference to the drawing, in the single figure of which a device for applying reinforcement notes to sections to be torn off from a web is schematically illustrated in a side view.

In einer Abwickelvorrichtung 1 ist eine Wickelrolle 2 drehbar gelagert. Von dieser Wickelrolle 2 wird die Bahn 3 abgezogen, und zwar durch mehrere untere mit Abstand nebeneinander liegende über Rollen 4 geführte Endlosbänder 5 sowie durch obere auf einer Achse mit Abstand nebeneinander liegende Rollen 6. Die Bahn 3 selbst besteht aus einer Kette von Windelbeuteln, die miteinander über nicht dargestellte Perforationslinien verbunden sind. Im Bereich der Zwischenräume zwischen den Endlosbändern 5 sind Gegenwalzen 7 vorgesehen, die mit einem Segment 8 zusammen­wirken. Letzteres weist zum einen einen Saugkanal 9 und zum anderen eine Messerschneide 10 auf. Diese Messerschneide 10 wirkt mit einem rotierenden Gegenmesser 11 derart zusammen, daß von einer über ein Saugband 12 zugeführten beleimten Endlosbahn 13 einzelne Zettel 14 abgetrennt und vom Saugkanal 9 gehalten werden. Wie aus der Figur zu ersehen, ist dem Segment 8 nicht nur das rotierende Messer, sondern ebenfalls noch eine rotierende Stanzeinrichtung 15 zugeordnet, durch in die einzelnen Zettel 14 jeweils Löcher eingestanzt werden. Während der weiteren Drehbewegung des Segmentes 8 in Pfeilrichtung A werden die einzelnen Zettel 14 jeweils auf einen Windelbeutel 16 im Zusammenwirken mit den Gegenwalzen 7 aufgepreßt. Da die Walzen 7 und die parallel mit abstand zueinander angeordneten Segmente 8 in dem Moment, in dem die Segmente 8 in Berührung mit der Bahn 3 kommen, schneller laufen als die Bahn selbst, wird von der Bahn durch die Segmente 8 jeweils ein Windelbeutel 16 abgerissen. Die Segmente 8 dienen folglich zum einen dem Abreißen einzelner Windelbeutel 16 von der Windelbeutelketten­bahn 3 und zum anderen dem Anpressen von beispielsweise Verstärkungszetteln auf einzelne Windelbeutel. Die mit dem Zettel 14 beklebten Windelbeutel 16 werden dann von der Bänder­führung 5 über ein oberes Saugband 17 abgenommen und durch einen Niederdrücker 18 auf die Stifte 19 eines Stapelbandes 20 in an sich bekannter Weise abgelegt.In a unwinding device 1, a winding roll 2 is rotatably mounted. From this winding roll 2, the web 3 is drawn off, namely through a plurality of lower endless belts 5, which are spaced next to one another and guided by rollers 4, and by upper rollers 6, which are spaced apart on an axis. The web 3 itself consists of a chain of diaper bags which are connected to one another via perforation lines, not shown. In the area of the gaps between the endless belts 5, counter-rollers 7 are provided which interact with a segment 8. The latter has a suction channel 9 on the one hand and a knife edge 10 on the other. This knife edge 10 interacts with a rotating counter knife 11 in such a way that individual slips 14 are separated from a glued endless web 13 fed via a suction belt 12 and held by the suction channel 9 will. As can be seen from the figure, not only the rotating knife but also a rotating punching device 15 is also assigned to the segment 8, through which holes are punched into the individual pieces of paper 14. During the further rotation of the segment 8 in the direction of arrow A, the individual pieces of paper 14 are each pressed onto a diaper bag 16 in cooperation with the counter-rollers 7. Since the rollers 7 and the segments 8 arranged parallel and at a distance from one another run faster than the web itself at the moment when the segments 8 come into contact with the web itself, a diaper bag 16 is torn off the web through the segments 8 . The segments 8 consequently serve, on the one hand, to tear off individual diaper bags 16 from the diaper bag chain track 3 and, on the other hand, to press reinforcement sheets onto individual diaper bags, for example. The diaper bags 16 stuck with the note 14 are then removed from the tape guide 5 via an upper suction tape 17 and deposited by a depressor 18 onto the pins 19 of a stacking tape 20 in a manner known per se.
