Description

Die Erfindung betrifft eine Vorrichtung zum Bilden und Stapeln von von einer Folienschlauchbahn oder einer Materialbahn abgetrennten Abschnitten oder abgeschweißten Beutel-oder Sackwerkstücken mit einer von der intermittierend voranbewegten Materialbahn Abschnitte abtrennenden oder abschweißenden Querschneid- oder Querschweißeinrichtung und einer den jeweils abgetrennten Abschnitt festklemmenden Einrichtung, mit einem die abgetrennten Abschnitte übernehmenden Saugbandförderer, dessen Bänder in einem Abstand, der größer ist als die Länge der Abschnitte, mit Sauglöchern versehen sind, und mit einer im Takt der Lüftung der festhaltenden Einrichtung gegen das Aufgabeende des Saugbandförderers bewegbaren und abhebbaren Andrückwalze, deren Andrückbewegung mit dem Durchlauf der Sauglöcher derart synchronisiert ist, daß jeder Abschnitt mit seinem hinteren Bereich von den Sauglöchern angesaugt wird.The invention relates to a device for forming and stacking sections or welded bag or bag workpieces separated from a film tube web or a material web, with a cross cutting or cross welding device that cuts off or welds off the intermittently moving material web sections and a device that clamps the respectively separated section the separated sections take over suction belt conveyor, the belts of which are provided with suction holes at a distance which is greater than the length of the sections, and with a pressure roller which can be moved and lifted in time with the release of the holding device against the feeding end of the suction belt conveyor, the pressure movement of which with the Passage of the suction holes is synchronized in such a way that each section with its rear area is sucked in by the suction holes.

Bei einer aus der DE-OS 29 15 689 bekannten Vorrichtung dieser Art wird der jeweilige Abschnitt im Bereich seines hinteren Endes von dem Untertrum eines Saugbandförderers angesaugt, wobei der vordere Bereich des Abschnitts von einem zu dem Abgabeende des oberen Saugbandförderers hin spitzwinkelig ansteigenden und mit höherer Fördergeschwindigkeit umlaufenden Saugbandförderer straff gehalten wird und zur Stapelbildung hinter dem Abgabeende beider Förderer eine die Abschnitte an ihrem vorderen Ende aufnadelnde Trommel vorgesehen ist, die im Takt der Zuführung der Abschnitte mit der Fördergeschwindigkeit des oberen Saugbandförderers umläuft.In a device of this type known from DE-OS 29 15 689, the respective section in the region of its rear end is sucked in by the lower run of a suction belt conveyor, the front region of the section rising from an acute angle to the discharge end of the upper suction belt conveyor and with a higher one conveying speed orbiting S is held taut and augbandförderer for stack formation behind the delivery end of a conveyor of both the sections is provided at its front end aufnadelnde drum, which rotates in step with the feed of the sections with the conveying speed of the upper suction belt conveyor.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der bekannten Art derart abzuwandeln, daß sich Stapel aus Abschnitten, insbesondere aus leichtem, empfindlichem und knitterndem Material, ohne Aufnadelung durch aufeinander erfolgendes Ablegen bilden lassen.The object of the present invention is to modify a device of the known type in such a way that stacks of sections, in particular of light, sensitive and creasing material, can be formed without needling by depositing them successively.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der mit seinem Obertrum fördernde Saugbandförderer in seinem Endbereich teilweise von einem zweiten, die Abschnitte übernehmenden und diese mit seinem Untertrum fördernden Saugbandförderer überdeckt ist, dessen Bänder ebenfalls in einem Abstand, der größer ist als die Länge der Abschnitte, mit Sauglöchern versehen ist, die die von dem ersten Saugbandförderer zugeführten Abschnitte in ihrem vorderen Bereich ansaugen, und daß unter dem zweiten Saugbandförderer ein intermittierend angetriebener Stapelbandförderer angeordnet ist, auf den die Abschnitts durch eine diese zu dem zweiten Saugbandförderer abziehende Einrichtung abgelegt werden. Die erfindungsgemäße Vorrichtung ermöglicht die Bildung von Stapeln aus Abschnitten, auch aus dünnem, leichtem und knitterndem Material, weil die Abschnitte beginnend mit ihrer Trennung von der Materialbahn ständig.von Halteeinrichtungen lagerichtig festgehalten, während ihres Transports fixiert und durch besondere Abzieheinrichtungen abgelegt werden.According to the invention, this object is achieved in that the suction belt conveyor conveying with its upper strand is partially covered in its end region by a second suction belt conveyor which takes over the sections and conveys these with its lower strand, the belts of which are also at a distance which is greater than the length of the sections , is provided with suction holes which suck in the sections fed from the first suction belt conveyor in its front region, and that an intermittently driven stacking belt conveyor is arranged under the second suction belt conveyor, on which the sections are deposited by a device pulling them off to the second suction belt conveyor. The device according to the invention enables the formation of stacks of sections, also of thin, light and creasing material, because the sections, starting with their separation from the material web, are constantly held in the correct position by holding devices, fixed during their transport and deposited by special pulling devices.

Aus der DE-AS 12 99 515 ist eine Vorrichtung zum Stapeln von dünnwandigen Folienabschnitten bekannt, bei der die Folienabschnitte von dem Untertrum eines Saugbandförderers intermittierend über den sich bildenden Stapel bzw. die Ablagestelle transportiert und dort während des Stillstandes der Abschnitte von einem Niederschläger von dem Saugband gelöst werden. Bei dieser bekannten Vorrichtung ist nicht nur die Stapelgeschwindigkeit durch den intermittierenden Antrieb des die Abschnitte zur Stapelstation führenden Saugbandes begrenzt, eine lagegenaue Fixierung der Abschnitte auf dem Saugbandförderer ist weiterhin auch nicht gewährleistet.From DE-AS 12 99 515 a device for stacking thin-walled film sections is known, in which the film sections are intermittently transported from the lower run of a suction belt conveyor over the stack that is being formed or the storage location, and from where a section of a precipitate is stopped by a precipitate Suction tape can be released. In this known device, not only is the stacking speed limited by the intermittent drive of the suction belt leading the sections to the stacking station, an exact position of the sections on the suction belt conveyor is also not guaranteed.

Aus der DE-AS 28 32 660 ist es an sich bekannt, von dem Untertrum eines Saugbandförderers an den vorderen Enden angesaugte Abschnitte zu einer Stapelstation zu fördern.From DE-AS 28 32 660 it is known per se to convey sections sucked in from the lower run of a suction belt conveyor at the front ends to a stacking station.

Zweckmäßigerweise besteht die abziehende Einrichtung aus durch die zwischen den Bändern gebildeten Spalte greifenden Stempeln, die die losen hinteren Enden der Abschnitte gegen eine Unterlage, den Stapelbandförderer oder auf den sich bildenden Stapel drücken. Die vorderen Enden der Abschnitte legen sich sodann nach ihrem Abfallen oder Abziehen von den Sauglöchern lagerichtig auf den Stapel.The pulling device expediently consists of punches, which extend between the gaps formed between the belts and press the loose rear ends of the sections against a support, the stacking belt conveyor or on the stack which is being formed. The front ends of the sections then lie in the correct position on the stack after they have fallen off or been pulled off from the suction holes.

Die Unterlage kann aus einer Saugleiste bestehen, die die Lage des ersten Abschnitts eines Stapels sichert.The base can consist of a suction bar, which secures the position of the first section of a stack.

Zweckmäßigerweise ist im vorderen Bereich des zweiten Stapelbandförderers ein durch die Spalte greifender absenkbarer Rechen angeordnet, der den jeweils letzten Abschnitt eines jeden Stapels auf diesen drückt, mit diesem beim intermittierenden Vorzug des Stapelbandförderers verfahrbar ist und nach jedem Vorzug in seine Bereitschaftsstellung zurückkehrt. Der absenkbare Rechen fixiert die Stapel vor ihrem intermittierenden Abtransport und führt zu einer sauberen Trennung des letzten Abschnitts des letzten Stapels und des ersten Abschnitts des sich neu bildenden Stapels.A lowerable rake reaching through the gaps is expediently arranged in the front area of the second stacking belt conveyor, which presses the last section of each stack on it, can be moved with it during the intermittent preference of the stacking conveyor and returns to its ready position after each preference. The lowerable rake fixes the stacks before their intermittent removal and leads to a clean separation of the last section of the last stack and the first section of the newly forming stack.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur eine schematische Seitenansicht der Vorrichtung zum Bilden und Stapeln von Abschnitten darsgestellt 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 schematic side view of the device for forming and stacking sections is shown.

Eine von einer nicht dargestellten Vorratsrolle kommende Folienschlauchbahn 1 wird durch Vorzugsrollen 2 intermittierend vorgezogen und zwischen die geöffneten Backen einer Schweißeinrichtung 3 sowie durch die Klemmbacken einer Klemmeinrichtung 4 hindurchgeführt. Zum gestreckten Vortransport des vorderen Endes der Schlauchfolienbahn 1 sind zwei Blasdüsen 5, 6vorgesehen, die einen das vordere Ende der Folienschlauchbahn tragenden Luftstrom erzeugen. Sobald die Schlauchfolienbahn 1 die aus der Zeichnung ersichtliche Lage erreicht hat, wird durch nicht dargestellte Steuereinrichtungen der Vorzug ausgeschaltet und die Schweißeinrichtung betätigt, wobei sich gleichzeitig die Backen der Klemmeinrichtung 4 schließen. Nach dem Abtrennen eines Abschnitts wird die Schweißeinrichtung 3 wieder geöffnet.A film tube web 1 coming from a supply roll (not shown) is intermittently advanced by preferential rolls 2 and passed between the open jaws of a welding device 3 and through the clamping jaws of a clamping device 4. For the forward conveying of the front end of the tubular film web 1, two blowing nozzles 5, 6 are provided, which generate an air flow carrying the front end of the tubular film web. As soon as the tubular film web 1 has reached the position shown in the drawing, control devices (not shown) switch off the preference and actuate the welding device, the jaws of the clamping device 4 simultaneously closing. After a section has been severed, the welding device 3 is opened again.

Mit dem Absenken der von einer Kolen-Zylinder-Einheit betätigten Andrückwalze 7 öffnen sich auch die Backen der Klemmeinrichtung 4, so daß der Abschnitt in Kontakt mit dem oberen Trum des Saugbandförderers 8 gebracht und von diesem abgefördert wird. Der Saugbandförderer 8 besteht aus mehreren nebeneinander angeordneten endlosen Förderbändern, die über unter der Ebene der Unterseite des Obertrums angeordnete Saugkästen-laufen. Die einzelnen Förderbänder weisen Löcher 10, 11 auf, deren Abstand voneinander größer ist als die größte Beutellänge. Die einzelnen Löcher 10, 11 der Förderbänder bilden quer zur Förderrichtung verlaufende Sauglochreihen. Der Antrieb des Saugbandförderers 8 erfolgt in Abhängigkeit von der Kurbelwelle der Schweißeinrichtung 3, und zwar derart, daß jeweils bei einer Umdrehung der Kurbelwelle der Schweißeinrichtung eine Sauglochreihe um eine Teilung vorrückt. Die Vorrichtung ist derart gesteuert, daß sich die Andrückwalze 7 unter gleichzeitiger öffnung der Klemmeinrichtung 4 zu einem Zeitpunkt auf den Abschnitt absenkt, in dem die Entfernung der Andrückwalze 7 zu dem hinteren Ende des Abschnitts der Entfernung bis zu der nächsten Sauglochreihe entspricht, so daß das hintere Ende des Abschnitts mit dieser Sauglochreihe zur Deckung gebracht wird. Auf diese Weise wird jeweils nur das hintere Ende des auf dem Saugbandförderer 8 liegenden Abschnitts 12 festgehalten, während der übrige Bereich des Abschnitts 12 frei auf dem Saugbandförderer 8 aufliegt. Das Abgabeende des Saugbandförderers 8 ist von dem Untertrum eines zweiten Saugbandförderers 13 überdeckt, der ebenfalls aus mehreren nebeneinander angeordneten schmalen endlosen Bändern besteht.With the lowering of the pressure roller 7 actuated by a piston-cylinder unit, the jaws of the clamping device 4 also open, so that the section comes into contact with the upper run brought of the suction belt conveyor 8 and is transported away from this. The suction belt conveyor 8 consists of a plurality of endless conveyor belts arranged side by side, which run over suction boxes arranged below the level of the underside of the upper run. The individual conveyor belts have holes 10, 11 whose spacing from one another is greater than the greatest bag length. The individual holes 10, 11 of the conveyor belts form rows of suction holes running transversely to the conveying direction. The suction belt conveyor 8 is driven as a function of the crankshaft of the welding device 3, in such a way that one row of suction holes advances each time the crankshaft of the welding device rotates. The device is controlled in such a way that the pressure roller 7, while simultaneously opening the clamping device 4, descends to the section at a time in which the distance of the pressure roller 7 to the rear end of the section corresponds to the distance to the next row of suction holes, so that rear end of the section is made to coincide with this row of suction holes. In this way, only the rear end of the section 12 lying on the suction belt conveyor 8 is held in place, while the rest of the section 12 lies freely on the suction belt conveyor 8. The discharge end of the suction belt conveyor 8 is covered by the lower run of a second suction belt conveyor 13, which also consists of several narrow endless belts arranged side by side.

Die Bänder des Untertrums laufen ebenfalls über Saugkästen 4. Auch die Bänder des zweiten Saugbandförderers 13 sind in entsprechender Weise wie der Saugbandförderer 8 mit Sauglochreihen 15 versehen, deren Abstände denen des Saugbandförderers 8 entsprechen. Die Sauglochreihen der beiden Saugbandförderer 8, 13 sind derart aufeinander abgestimmt, daß die Sauglochreihen 15 die auf den Saugbandförderer 8 geförderten Abschnitte 12 an ihren vorderen Enden ansaugen. Auf diese Weise werden die Abschnitte 12 sowohl an ihren vorderen als auch an ihren hinteren Enden durch die Sauglochreihen gehalten. Nachdem sich der Abschnitt 12 während seines weiteren Transportes durch den Saugbandförderer 13 von der Sauglochreihe 11 oder 12 gelöst hat, wird es frei hängend von der Sauglochreihe 15 weitertransportiert, bis sich der Abschnitt 12 oberhalb des zu bildenden Stapels befindet. In dieser Stellung liegt das hintere Ende des Abschnitts 12 oberhalb einer Saugleiste 16. Sowie der Abschnitt 12 diese Stellung erreicht hat, fahren die Stempel 17 eines Niederschlägers 18 aus, greifen zwischen die Bänder des Saugbandförderers 13 und drücken das hintere Ende des Abschnitts 12 auf die Saugleiste 16 bzw. den sich gerade bildenden Stapel. Dadurch, daß der Abschnitt 12 durch die Stempel 17 an seinem hinteren Ende festgehalten wird, wird das vordere Ende des Abschnitts 12 von der Sauglochreihe 15 abgezogen. Nach dieser Ablage des Abschnitts 12 wird der Stempel 17 wieder zurückgezogen.The belts of the lower run also run over suction boxes 4. The belts of the second suction belt conveyor 13 are provided in the same way as the suction belt conveyor 8 with rows of suction holes 15, the spacing of which corresponds to that of the suction belt conveyor 8. The rows of suction holes of the two suction belt conveyors 8, 13 are matched to one another such that the rows of suction holes 15 contact the sections 12 conveyed onto the suction belt conveyor 8 suck their front ends. In this way, the sections 12 are held by the rows of suction holes at both their front and rear ends. After the section 12 has detached from the suction hole row 11 or 12 during its further transport by the suction belt conveyor 13, it is transported freely suspended from the suction hole row 15 until the section 12 is above the stack to be formed. In this position, the rear end of the portion 12 is located above a suction bar 16 and the section 12 has reached this position, the stamp drive 17 of a low-bat 18, grab between the bands of the S augbandförderers 13 and push the rear end of the portion 12 the suction bar 16 or the stack being formed. Characterized in that the section 12 is held by the punch 17 at its rear end, the front end of the section 12 is withdrawn from the suction hole row 15. After this storage of section 12, the stamp 17 is withdrawn again.

Unterhalb der Saugleiste 16 befindet sich ein Stapelbandförderer 20, auf dem die Stapelbildung erfolgt. Ist ein Stapel mit der gewünschten Abschnittzahl gebildet worden, senkt sich ein im Bereich des Abgabeendes des Saugbandförderers 13 angeordneter Fingerrechen 19 nach unten ab und drückt den gebildeten Stapel auf das Stapelförderband 20. Mit derselben Fördergeschwindigkeit,; mit der das Stapelförderband 20 den zuletzt gebildeten Stapel intermittierend um die Strecke x in Richtung des Pfeils A befördert, bewegt sich der Finderrechen 19 mit diesem. Zu diesem Zweck ist der Absenkzylinder 21 des Fingerrechens 19 in einer Konsole gelagert, die ihrerseits an einer Führung 22 befestigt ist, die an ihrem Ende eine Zahnstange 23 aufweist. Die Zahnstange 23 kämmt mit einem Ritzel 24 eines Elektromotors 25, der gleichzeitig den intermittierenden Antrieb des Stapelförderbandes 20 dient.Below the suction bar 16 there is a stacking belt conveyor 20 on which the stacking takes place. If a stack with the desired number of sections has been formed, a finger rake 19 arranged in the area of the discharge end of the suction belt conveyor 13 lowers and presses the stack formed onto the stack conveyor belt 20. With the same conveying speed; with which the stacking conveyor belt 20 intermittently conveys the last stack formed by the distance x in the direction of arrow A, the finder rake 19 moves with it. For this purpose, the lowering cylinder 21 of the finger rake 19 is mounted in a console, which in turn is fastened to a guide 22 which has a toothed rack 23 at its end. The rack 23 meshes with a pinion 24 of an electric motor 25, which at the same time serves the intermittent drive of the stacking conveyor belt 20.

Nachdem das Stapelförderband 20 die Stapel um die Strecke x in Richtung des Pfeils A voranbewegt hat, wird es wieder ausgeschaltet, der.Zylinder 21 eingefahren und der Fingerrechen in seine aus der Zeichnung ersichtliche Ausgangsstellung zurückgefahren.After the stack conveyor belt has x above 20 moves the stack by a distance in the direction of arrow A, it is switched off again, retracted der.Zylinder 21 and the F inger rake in its apparent from the drawing starting position retracted.

Während des Laufs des Stapelbandförderers 20 hat der Saugbandförderer 13 bereits wieder Abschnitte 12 herantransportiert und diese durch den Stempel 17 auf die Saugleiste 16 gedrückt. Die Saugleiste 16 hält den ersten auf diesem abgelegten Beutel fest, so daß zum einen durch den abzuführenden Beutelstapel der erste von der Saugleiste 16 festgehaltene Stapel geglättet und zum anderen ein Verrutschen der weiter auf die Saugleiste 16 abgelegten Abschnitte verhindert wird.During the course of the stacking belt conveyor 20, the suction belt conveyor 13 has already transported sections 12 back and pressed them onto the suction bar 16 by the punch 17. The suction bar 16 holds the first bag placed on it, so that on the one hand the first stack held by the suction bar 16 is smoothed by the stack of bags to be discharged and on the other hand slipping of the sections further deposited on the suction bar 16 is prevented.

Bei einem Formatwechsel ist es lediglich erforderlich, die Sauglochreihen der Saugbandförderer 8 und 13 durch Verdrehen der Bänder auf das neue Format einzustellen.When changing the format, it is only necessary to adjust the suction hole rows of the suction belt conveyors 8 and 13 to the new format by rotating the belts.
