Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 und eine Vorrichtung nach dem Oberbegriff des Anspruchs 3.The invention relates to a method according to the preamble of Claim 1 and a device according to the preamble of the claim 3rd

Ein solches Verfahren und eine solche Vorrichtung sind aus der DE 12 99 548 A1 und der DE 24 50 373 A1 bekannt. Dort sind unterhalb eines Spalts, der eine erste und eine zweite Förderstrecke voneinander trennt, eine Zange und ein Schlagmesser angeordnet, welches entweder ein gesondertes, durch die geöffnete Zange hindurch bewegbares Bauteil sein (DE 12 99 548 A1) oder zugleich einen Zangenbacken bilden kann (DE 24 50 373 A1). Jeder Arbeitszyklus beginnt damit, daß das untere Ende einer senkrecht von oben nach unten zugeführten Folienbahn in der Zange festgeklemmt wird, ehe ein zu umwickelnder Quader gegen die Folienbahn gedrückt wird. Bei der weiteren Bewegung des Quaders gleitet dessen Unterseite über die Folienbahn und diese wird über die Vorderseite und über die Oberseite des Quaders von oben her nachgezogen. Sobald der Quader vollständig über den Spalt hinwegbewegt worden ist, wird ein bis dahin oberhalb des Quaders liegend angeordneter, die Folienbahn führender Ziehbalken oder Mitnehmer hinter dem Quader durch den Spalt hindurch abgesenkt, wobei er die Folienbahn mitnimmt, so daß diese die Rückseite des Quaders bedeckt und sich schließlich unterhalb davon mit dem noch in der Zange festgehaltenen ersten Ende der Folienbahn überlappt, mit diesem verschweißt und dann mittels des Schlagmessers abgetrennt wird. Das dadurch freiwerdende untere Ende der von oben kommenden Folienbahn wird vorübergehend zwischen dem Mitnehmer und einer Anpreßleiste festgeklemmt, dann weiter nach unten geführt und von der Zange festgehalten. Sodann kehrt der Mitnehmer in seine obere Endstellung zurück und gibt den Weg frei für den nächsten zu umhüllenden Quader. Such a method and such a device are known from the DE 12 99 548 A1 and DE 24 50 373 A1 are known. There are below a gap, the first and a second conveyor line separates from each other, a pair of pliers and a fly knife arranged, which is either a separate, through the open Forceps that can be moved through the pliers (DE 12 99 548 A1) or can simultaneously form a pair of pliers jaws (DE 24 50 373 A1). Each cycle begins with the bottom of one vertically from top to bottom fed film web in the Pliers are clamped before a cuboid to be wrapped against the film web is pressed. With the further movement of the Cubers slides its underside over the film web and this is over the front and over the top of the cuboid pulled from above. Once the cuboid is completely over the gap has been moved one up to then of the cuboid arranged drawing bar leading the film web or driver behind the cuboid through the gap lowered, taking the film web with it, so that it covered the back of the cuboid and finally below of which with the first end still held in the pliers the film overlap, welded to it and then is separated by means of the fly knife. That which frees up the lower end of the film web coming from above becomes temporary clamped between the driver and a pressure bar, then continued down and off the pliers captured. The driver then returns to its upper end position back and clears the way for the next one to be wrapped Cuboid.

Die auf diese bekannte Weise zum Umhüllen von Quadern verwendete Folie besteht aus Kunststoff wie PVC oder PE und ist somit hinreichend glatt und reißfest, um in der beschriebenen Weise über die Unterseite, Vorderseite und Oberseite jedes Quaders gleiten zu können, wobei die Relativgeschwindigkeit zwischen Folie und Quader an dessen Unter- und Vorderseite ebensogroß, an dessen Oberseite jedoch doppeltsogroß wie die Bewegungsgeschwindigkeit des Quaders ist. Die dabei entstehenden Reibungswiderstände sind nur dann beherrschbar, wenn der Quader selbst ebenso wie die Folie glatt ist. Unabhängig davon lassen sich nur solche Folien verwenden, die entlang der zwischen der Unterseite und der Rückseite des Quaders gebildeten Kante eine hinreichend feste aber doch nicht abstehende Schweißnaht bilden. Zum Umwickeln von Quadern mit rauherem, weniger reißfestem und nicht in einer schmalen Naht verschweißbarem Bahnmaterial wie beispielsweise Packpapier eignen sich die beschriebene bekannte Verfahrensweise und Vorrichtung nicht.The one used in this known way for enveloping cuboids Foil is made of plastic such as PVC or PE and is therefore sufficiently smooth and tear-resistant to in the manner described across the bottom, front, and top of each box to be able to slide, the relative speed between Foil and cuboid on the underside and front just as big, on the top, however, twice as large as the speed of movement of the cuboid. The resulting frictional resistances are only manageable if the cuboid even as the film is smooth. Leave regardless only use foils that run along the line between the Underside and back of the cuboid formed an edge form a sufficiently firm but not protruding weld seam. For wrapping cuboids with rougher, less tear-resistant and not in a narrow seam weldable web material such as wrapping paper, the known ones described are suitable Procedure and device not.

Aus der DE 11 70 859 A1 ist eine Vorrichtung zum Umwickeln von Quadern bekannt, die drei hintereiander angeordnete, von den Quadern nacheinander zu durchlaufende Fördertunnel aufweist. Der erste Fördertunnel weist einen querliegenden Spalt auf, durch den hindurch von oben her eine Bahn aus Einwickelmaterial derart zugeführt wird, daß ihr unteres Ende unterhalb einer Bodenplatte des Tunnels, und ihr beim Durchtrennen der Bahn freiwerdendes oberes Ende oberhalb einer Deckplatte des Tunnels angeordnet ist. Sodann wird ein zu umhüllender Quader im ersten Fördertunnel vorwärts bewegt, so daß er sich mit seiner Vorderseite an den Bahnabschnitt anlegt und diesen mitnimmt, so daß er Schenkel bildet, die sich auch an die Unterseite und an die Oberseite des Quaders anlegen und nach hinten überstehen. Am Übergang zwischen dem ersten und dem zweiten Fördertunnel weisen die Deckplatte und die Bodenplatte Lücken auf, durch die hindurch zunächst ein Mitnehmer eines endlosen oberen Förderers von oben her in den zweiten Fördertunnel eintaucht und dabei den oberen Überstand der Bahn gegen die Rückseite drückt, und dann in entsprechender Weise ein mit einem unteren endlosen Förderer umlaufenden Mitnehmer von unten her in den zweiten Fördertunnel eingreift und den unteren Überstand der Bahn ebenfalls gegen die Rückseite des Quaders drückt. Dabei wird der Quader zunächst von dem Mitnehmer des oberen Förderers und dann von dem Mitnehmer des unteren Förderers vorwärts geschoben. Damit letzterer den Quader erreichen kann, muß der untere Förderer zeitweise mit erhöhter Geschwindigkeit angetrieben werden.DE 11 70 859 A1 describes a device for wrapping around Cuboids known, the three arranged one behind the other of the Having cubes of conveying tunnels to be passed through one after the other. The first production tunnel has a transverse gap, through which a sheet of wrapping material passes from above is fed such that its lower end below one Bottom plate of the tunnel, and her cutting the track The free upper end above a cover plate of the tunnel is arranged. Then a cuboid to be encased in the first Production tunnel moves forward so that it is with its front puts on the track section and takes it, so that it forms thighs that also extend to the underside and to the Place the top of the cuboid and protrude to the rear. At the Transition between the first and second production tunnels have gaps in the cover plate and the base plate through which initially a driver of an endless upper conveyor immersed in the second conveyor tunnel from above while doing so presses the top of the web against the back, and then correspondingly one with a lower endless Conveyor rotating carrier from below into the second Production tunnel intervenes and the lower overhang of the railway also pushes against the back of the cuboid. The Cuboid first from the driver of the upper conveyor and then pushed forward by the driver of the lower conveyor. So that the latter can reach the cuboid, the lower conveyor must temporarily driven at increased speed.

Mit dieser bekannten Vorrichtung lassen sich auch Quader umwickeln, die nicht besonders glatt sind, und dazu läßt sich auch nicht besonders reißfestes Einwickelmaterial, beispielsweise Packpapier verwenden; die Vorrichtung ist aber aufwendig und beansprucht viel Platz.With this known device, cuboids can also be wrapped, which are not particularly smooth, and can be also not particularly tear-resistant wrapping material, for example Use wrapping paper; the device is complex and takes up a lot of space.

Eine weitere Vorrichtung zum Umwickeln von Ballen ist aus dem Prospekt "Wrapper Applying Machine Type ERA" der Sunds Defibrator AB, S-85194 Sundsvall, Schweden (Druckereivermerk E-06/85) bekannt. Dort sind die beiden Förderstrecken im rechten Winkel zu einem Hauptförderer angeordnet, der von Isolierstoffballen gebildete Quader heranfördert. Die erste Förderstrecke ist heb- und senkbar, um bei jedem Maschinenzyklus einen Quader vom Hauptförderer zu übernehmen und in Richtung zur zweiten Förderstrecke zu fördern. Die zweite Förderstrecke ist als Ganzes in Richtung zur ersten Förderstrecke hin und von dieser weg verstellbar, und die Förderrichtung beider Förderstrecken ist umkehrbar. Als Einwickelmaterial dienendes Papier wird von einer Rolle abgezogen und unterhalb der zweiten Förderstrecke in einen Bereich unterhalb des zwischen den beiden Förderstrecken gebildeten Spalts gefördert. Die Maschine hat ein Paar seitlich neben dem Spalt angeordnete Ständer, in denen ein als Wickelrolle ausgebildeter Mitnehmer gelagert und auf- und abbeweglich geführt ist.Another device for wrapping bales is out the brochure "Wrapper Applying Machine Type ERA" from the Sunds Defibrator AB, S-85194 Sundsvall, Sweden (printer's note E-06/85) known. The two conveyor lines are there arranged at right angles to a main conveyor which is of Insulated bales of cuboids. The first Conveyor line can be raised and lowered to every machine cycle to take over a cuboid from the main conveyor and into To promote direction to the second conveyor line. The second conveyor line is as a whole towards the first conveyor line adjustable to and from this, and the conveying direction of both Conveyor routes are reversible. As wrapping material serving paper is pulled from a roll and below the second conveyor line in an area below the promoted gap formed between the two conveyor lines. The machine has a pair located to the side of the gap Stand in which a driver designed as a winding roll stored and guided up and down.

Ehe der von der ersten Förderstrecke übernommene Quader den Spalt erreicht, taucht der Mitnehmer der bekannten Vorrichtung durch den weit geöffneten Spalt hindurch nach unten, erfaßt das dort bereitgehaltene Ende der Bahn, wickelt einen Bahnabschnitt auf und kehrt in seine obere Endstellung zurück. Sodann wird die Bahn unterhalb des Spalts abgetrennt, sodaß sie vom Mitnehmer lose durch den Spalt nach unten hängt. Die zweite Förderstrecke nähert sich der ersten, um den von dieser heranbewegten Quader zu übernehmen. Dessen Vorderseite stößt gegen den senkrecht herabhängenden Bahnabschnitt, der bei der Fortbewegung des Quaders allmählich vom Mitnehmer abgewickelt wird. Sobald der Quader den Spalt passiert hat, wird dieser wieder weit geöffnet und der Mitnehmer taucht mit dem noch von ihm festgehaltenen Bahnende durch den Spalt hindurch nach unten, wo er das Bahnende freigibt. Sodann wird die Fördereinrichtung beider Förderstrecken umgekehrt und die zweite Förderstrecke nähert sich der ersten, so daß diese den Quader wieder übernimmt. Bei der Rückwärtsbewegung des Quaders auf der ersten Förderstrecke gelangt das bisher vom Greifer festgehaltene Bahnende an die Unterseite des Quaders und überlappt sich mit dem entgegengesetzten Bahnende. Schließlich wird der Ballen wieder vom Hauptförderer übernommen, und erst dann kann ein neuer Maschinenzyklus stattfinden, bei dem der nächste vom Hauptförderer herangebrachte Quader umwickelt wird. Dieses bekannte Verfahren und die zu seiner Durchführung verwendete Vorrichtung haben für das Umwickeln jedes Ballens vorallem wegen dessen notwendiger Hin- und Herbewegung einen erheblichen Zeitbedarf.Before the cuboid taken over from the first conveyor line When the gap is reached, the driver of the known device dips through the wide open gap down, grasp that End of the web held there, winds a web section and returns to its upper end position. Then will the web separated below the gap, so that it from the driver hanging loosely through the gap. The second conveyor line approaches the first one by the one it is moving towards Take over cuboid. Its front side bumps into the vertically hanging track section, which is used for locomotion of the cuboid is gradually handled by the driver. As soon as the cuboid has passed the gap, it will again wide open and the driver dives with him trapped web end down through the gap where he releases the end of the web. Then the conveyor is both Conveyor lines reversed and the second conveyor line approaches the first so that it takes over the cuboid again. At the backward movement of the cuboid on the first conveyor line the web end previously held by the gripper reaches the Underside of the cuboid and overlaps with the opposite Web end. Finally, the bale is back from the main conveyor and only then can a new machine cycle be started take place where the next one brought in from the main sponsor Cuboid is wrapped. This known method and the device used to carry it out for Wrapping each bale mainly because of the necessary round-trip Movement a considerable amount of time.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Umwickeln von Quadern, insbesondere Isolierstoffballen, mit einer Bahn aus Einwickelmaterial, insbesondere Papier, derart zu gestalten, daß bei gegebenen Abmessungen der Quader kürzere Bearbeitungszeiten erreichbar sind und der Vorrichtungsaufwand verringert wird.The invention has for its object a method and a device for wrapping cuboids, in particular bales of insulating material, with a web of wrapping material, in particular Paper to be designed so that given Dimensions of the cuboid shorter machining times can be achieved are and the device effort is reduced.

Oberhalb der zweiten Förderstrecke 13 ist eine waagerechte Andrückplatte 20 angeordnet, die mittels einer Scherenanordnung 21 am Gestell 10 aufgehängt und mittels eines Stelltriebs 22 parallel zu sich selbst verstellbar ist, um sich unterschiedlichen Höhen der Quader 1 anzupassen.Above the second conveyor section 13 is a horizontal pressure plate 20 arranged by means of a scissor assembly 21 suspended on the frame 10 and by means of an actuator 22 parallel to itself is adjustable to be different Adjust the heights of the cuboid 1.

Auf dem Gestell 10 ist ein Magazin 23 mit zwei Lagerböcken 24 für je eine Papierrolle 25 angeordnet. Von jeder dieser Rollen 25 läßt sich Papier in einer Bahn 2 abziehen, wobei die Wahl besteht, jeweils eine der Rollen 25 als Ersatzrolle bereitzuhalten oder das Papier von beiden Rollen 25 gleichzeitig abzuziehen, wenn eine zweilagige Bahn zum Umwickeln der Quader 1 verwendet werden soll. Es ist auch möglich, auf den beiden Rollen 25 Bahnen 2 unterschiedlicher Breite bereitzuhalten.On the frame 10 there is a magazine 23 with two bearing blocks 24 arranged for one roll of paper 25 each. From each of these roles 25 paper can be drawn off in a web 2, the choice being consists of keeping one of the rollers 25 available as a replacement roller or pull the paper from both rolls 25 at the same time, if a two-layer web for wrapping the cuboid 1 should be used. It is also possible on the two Rolls 25 sheets 2 of different widths ready.

Die Bahn 2 läuft entweder über eine Umlenkrolle 26 an einem der Lagerböcke 24 oder direkt nach oben zu einem ersten Portal 27 über eine dort gelagerte zweite Umlenkrolle 28, durch einen ebenfalls an diesem Portal 27 gelagerten, rahmenförmigen Tänzer 29 hindurch über eine an diesem gelagerte dritte Umlenkrolle 30. Der Tänzer 29 ist mit dem ersten Portal 27 durch einen regelbaren Stelltrieb 31 verbunden, der es ermöglicht, in der Bahn 2 eine vorgewählte Spannung aufrechtzuerhalten. Von der dritten Umlenkrolle 30 erstreckt sich die Bahn 2 wieder nach oben zu einem zweiten Portal 32 und um eine dort angeordnete Umlenkung 33, die ebenfalls eine Umlenkrolle sein kann. Senkrecht unterhalb dieser Umlenkung 33 ist eine Antriebswalze 34 angeordnet, die zusammen mit einer zweiten Antriebswalze 35 einen Walzenspalt bildet, durch den die Bahn 2 senkrecht nach unten hindurchgeführt wird. Sämtliche Umlenkrollen und Antriebswalzen haben waagerechte, in bezug auf die Förderrichtung 9 querliegende Achsen.The web 2 either runs over a deflection roller 26 on one of the Bearing blocks 24 or directly up to a first portal 27 via a second deflection roller 28 mounted there, by a also on this portal 27 frame-shaped dancers 29 through a third deflection roller mounted thereon 30. The dancer 29 is adjustable with the first portal 27 Actuator 31 connected, which makes it possible in the web 2nd maintain a preselected tension. From the third Deflection roller 30, the web 2 extends upwards again a second portal 32 and around a deflection arranged there 33, which can also be a pulley. Vertical below this deflection 33, a drive roller 34 is arranged, which together with a second drive roller 35 a nip forms, through which the web 2 is passed vertically downwards becomes. All pulleys and drive rollers have horizontal, 9 transverse to the direction of conveyance Axes.

Der Walzenspalt zwischen den Antriebswalzen 34 und 35 liegt senkrecht über dem Spalt 14 zwischen den beiden Förderstrecken 11 und 13. Unmittelbar unterhalb dieses Walzenspalts ist eine querliegende Schiene 36 angeordnet, an der eine Klebstoffauftrage- und Trennvorrichtung 37 entlangbewegbar ist. In geringem Abstand hinter der senkrechten Ebene, die durch die Umlenkung 33 und den Walzenspalt zwischen den Antriebswalzen 34 und 35 definiert ist, befindet sich der Arbeitsbereich eines Mitnehmers 38. Der Mitnehmer 38 ist ein waagerechtes Rohr, das sich quer zur Förderrichtung 9, also parallel zur Umlenkung 33 und den Antriebswalzen 34 und 35 erstreckt, eine perforierte Mantelfläche hat und intermittierend evakuierbar ist, wodurch die Bahn 2 an den Mitnehmer 38 ansaugbar und von ihm mitnehmbar ist.The nip is between the drive rollers 34 and 35 vertically above the gap 14 between the two conveyor lines 11 and 13. Immediately below this nip is one Transverse rail 36 is arranged, along which an adhesive application and separating device 37 can be moved. In a little Distance behind the vertical plane caused by the redirection 33 and the nip between the drive rollers 34 and 35 is defined, the work area of a driver is located 38. The driver 38 is a horizontal tube that transversely to the conveying direction 9, that is to say parallel to the deflection 33 and the drive rollers 34 and 35, a perforated Has lateral surface and can be evacuated intermittently, whereby the web 2 can be sucked onto the carrier 38 and can be carried by it is.

Der Mitnehmer 38 bildet den unteren Rand einer kufenartig gewölbten Bahnführung 39, die durch ein in ihrem oberen Drittel angeordnetes Gelenk 40 mit waagerechter, in bezug auf die Förderrichtung 9 querliegender Gelenkachse A mit einem Lenker 41 verbunden ist. Dieser ist durch ein Gelenk 42 mit ebenfalls waagerechter, in bezug auf die Förderrichtung 9 querliegender Gelenkachse B an der Andrückplatte 20 gelagert. Der Lenker 41 ist rahmenartig gestaltet und weist etwa in seiner Mitte eine Lagerstelle 43 auf, die durch einen Stelltrieb 44 mit einem oberen Endbereich der Bahnführung 39, und durch einen weiteren Stelltrieb 45 mit der Andrückplatte 20, verbunden ist. The driver 38 forms the lower edge of a skid-like arch Web guide 39 by a in its upper third arranged hinge 40 with horizontal, with respect to the conveying direction 9 transverse joint axis A with a link 41 connected is. This is also by a joint 42 horizontal, with respect to the conveying direction 9 transverse Hinge axis B mounted on the pressure plate 20. The handlebar 41 is designed like a frame and has one in the middle Bearing 43 on which by an actuator 44 with a upper end region of the web guide 39, and by another Actuator 45 is connected to the pressure plate 20.

Unterhalb des zwischen den beiden Förderstrecken 11 und 13 gebildeten Spalts 14 beginnt ein nach unten führender Kanal 46, der kreisbogenförmig nach vorne, in Förderrichtung 9, gebogen ist, sich über die gesamte Breite des Spalts 14 erstreckt und nach vorne hin allmählich enger wird. Der Kanal 46 ist an einer Traverse 47 angeordnet, die den Spalt 14 nach vorne hin begrenzt. An der Traverse 47 ist eine Klappe 48 mittels eines Gelenks 49 mit waagerechter, querliegender Achse C gelagert. Die Klappe 48 ist mit dem Gestell 10 durch einen Stelltrieb 50 verbunden; dadurch ist sie aus einer Ruhestellung, in der sie in der Ebene der zweiten Förderstrecke 13 liegt, in eine Andrückstellung schwenkbar, in der sie vom Gelenk 49 senkrecht nach oben ragt.Below that formed between the two conveyor lines 11 and 13 Gap 14 begins a channel 46 leading downwards, the arc-shaped forward, in the conveying direction 9, bent is, extends over the entire width of the gap 14 and gradually narrows towards the front. Channel 46 is on one Traverse 47 arranged, which limits the gap 14 towards the front. On the traverse 47 is a flap 48 by means of a Joint 49 mounted with a horizontal, transverse axis C. The flap 48 is connected to the frame 10 by an actuator 50 connected; thereby it is from a rest position in which it lies in the plane of the second conveyor section 13, in a pressing position pivotable, in which it vertically from the hinge 49 protrudes above.

Die Arbeitsweise der in Fig.1 bis 6 dargestellten Vorrichtung wird nun anhand der Fig.7 bis 12 näher erläutert:The operation of the device shown in Fig.1 to 6 is now explained in more detail with reference to FIGS. 7 to 12:

In Fig.7 nehmen der Schieber 12 und der Mitnehmer 38 ihre Ruhestellung ein. Nun setzt eine nicht dargestellte Zubringevorrichtung üblicher Bauart einen Quader 1 vor dem Schieber 12 ab, und der Mitnehmer 38 wird unter Vakuum gesetzt, so daß er das Ende der Bahn 2 ansaugt. Anschließend wird der Lenker 41 von seinem Stelltrieb 45 abwärts geschwenkt und der Stelltrieb 44 bewirkt eine geringfügige Korrekturbewegung der Bahnführung 39, so daß der Mitnehmer 38 ungefähr senkrecht abwärts bewegt wird. Die Bahn 2 wird von den Antriebswalzen 34 und 35 nach unten gefördert, sodaß sie sich zusammen mit der Bahnführung 39, an dieser anliegend, abwärts bewegt. Alternativ kann auf das Ansaugen der Bahn 2 durch den Mitnehmer 38 verzichtet werden und dieser kann samt Bahnführung 39 schon seine untere Stellung gemäß Fig.8 erreicht haben, wenn die Antriebswalzen 34 und 35 beginnen, die Bahn nach unten zu fördern. In jedem Fall wird die Bahn 2 von den Antriebswalzen 34 und 35 soweit nach unten gefördert, daß sie durch den Spalt 14 hindurch in den Kanal 46 eintritt, während der Mitnehmer 38 wieder aufwärts in seine Ruhestellung bewegt wird.In Figure 7, the slide 12 and the driver 38 take their rest position a. Now a feed device, not shown, sets customary construction from a cuboid 1 in front of the slide 12, and the driver 38 is placed under vacuum so that it End of web 2 sucks. Then the handlebar 41 of its actuator 45 is pivoted downward and the actuator 44 causes a slight correction movement of the web guide 39, so that the driver 38 is moved approximately vertically downwards. The web 2 is driven down by the drive rollers 34 and 35 promoted so that they together with the web guide 39, this adjacent, moved down. Alternatively, on the suction the web 2 can be dispensed with by the driver 38 and This can already be in its lower position together with web guide 39 8 have reached when the drive rollers 34 and 35th start conveying the web down. In any case the web 2 from the drive rollers 34 and 35 as far down promoted that they pass through the gap 14 into the channel 46th occurs while the driver 38 back up into his Rest position is moved.

Wenn der in Fig.9 abgebildete Zustand erreicht ist, wird der Schieber 12 nach links bewegt, so daß er den Quader 1 vorwärts schiebt. Dessen Vorderseite 3 drückt infolgedessen gegen den senkrecht herabhängenden Abschnitt der Bahn 2, wobei diese sich zunächst an die Vorderseite 3 und dann an die Oberseite 4 sowie gleichzeitig an die Unterseite 5 des Quader 1 anlegt, während dieser gemäß Fig.10 über den Spalt 14 hinweggeschoben wird. Dabei gleitet der untere Abschnitt der Bahn 2 über die waagerecht liegende Klappe 48, die einen gewissen Reibungswiderstand auf die Bahn ausübt. Die Antriebswalzen 34 und 35 sind während der in Fig.10 abgebildeten Vorwärtsbewegung des Quaders 1 unwirksam; der Tänzer 29 wirkt jedoch bremsend auf die Bahn 2. Infolgedessen wird die Bahn 2 straff über die Oberseite 4 und über die Unterseite 5 gezogen.When the state shown in Fig. 9 is reached, the Slider 12 moves to the left so that it moves the cuboid 1 forward pushes. Its front 3 consequently presses against the vertically depending section of the web 2, this being itself first to the front 3 and then to the top 4 as well simultaneously applies to the underside 5 of the cuboid 1, while this is pushed over the gap 14 according to FIG. The lower section of the web 2 slides horizontally lying flap 48 which has a certain frictional resistance exercised on the web. The drive rollers 34 and 35 are during the forward movement of the cuboid 1 shown in FIG. 10 is ineffective; however, the dancer 29 acts as a brake on the web 2. As a result the web 2 is taut over the top 4 and pulled over the bottom 5.

Sobald der Schieber 12 den Quader 1 vollständig über den Spalt 14 und zumindest im wesentlichen auch über die Klappe 48 hinweggeschoben hat, wird die Andrückplatte 20 gemäß Fig.11 abgesenkt, sodaß sie den Quader 1 festklemmt. Dann wird der Schieber 12 zurückgezogen und unmittelbar darauf wird die Klappe 48 nach oben geschwenkt, so daß sie das Ende der Bahn 2 an die Rückseite 6 des Quaders 1 anlegt. Gleichzeitig wird der Mitnehmer 38 gemäß Fig.11 abwärts bewegt, ohne jedoch unter Vakuum gesetzt zu werden. Infolgedessen gleitet der Mitnehmer 38 über die Bahn 2 und legt sie von oben nach unten an die Rückseite 6 des Quaders 1 an, während dieser weiterhin durch die von der Andrückplatte 20 auf ihn ausgeübte, nach unten gerichtete Kraft festgeklemmt wird.As soon as the slide 12 the cuboid 1 completely over the gap 14 and at least essentially pushed over the flap 48 the pressure plate 20 is lowered according to FIG. 11, so that it clamps the cuboid 1. Then the slider 12 withdrawn and immediately thereafter the flap 48 pivoted upwards, so that they the end of the web 2 to the Rear 6 of cuboid 1 creates. At the same time, the driver 38 moved downwards according to FIG. 11, but without being placed under vacuum to become. As a result, the driver 38 slides over lane 2 and lay it from top to bottom on the back 6 of the cuboid 1, while this continues by the of the Pressure plate 20 exerted on him downward force is clamped.

Im Verlauf der Abwärtsbewegung des Mitnehmers 38 wird die Bahn 2 von der Vorrichtung 37 durchtrennt, nachdem sie unmittelbar unterhalb der Trennstelle mit Klebstoff bestrichen oder besprüht worden ist. Der um den Quader 1 herumgewickelte Bahnabschnitt hat nun zwei Enden, die vom Mitnehmer 38 in eine überlappende Lage gemäß Fig.12 gebracht und miteinander verklebt werden. Anschließend wird die Andrückplatte 20 wieder aufwärts bewegt, so daß sie den Quader 1 freigibt und dieser von den Bandförderern 15 längs der zweiten Förderstrecke 13 weiterbewegt wird. Gleichzeitig werden der Mitnehmer 38 nach oben und die Klappe 48 nach unten in die Ruhestellung gemäß Fig.7 bewegt.In the course of the downward movement of the driver 38, the web 2 severed by device 37 immediately after it Brushed or sprayed below the separation point with adhesive has been. The web section wrapped around the cuboid 1 now has two ends that overlap from the driver 38 Position as shown in Fig.12 and glued together. Then the pressure plate 20 is moved up again, so that it releases the cuboid 1 and this from the belt conveyors 15 is moved along the second conveyor section 13. At the same time the driver 38 and the flap 48 moved down into the rest position according to Figure 7.
