Description

Die Erfindung betrifft eine Vorrichtung zum Transport von durch eine Banderole umgebenen Stapeln mit folgenden Merkmalen:

  • a) die Stapel sind auf einem Stapelförderer mit Abstand voneinander förderbar,
  • b) es ist ein Trennmesser vorgesehen, an dem die Stapel zum Durchtrennen der Banderolen an der Unterseite des Stapels vorbeibewegbar sind.
The invention relates to a device for transporting stacks surrounded by a band with the following features:
  • a) the stacks can be conveyed on a stack conveyor at a distance from one another,
  • b) a separating knife is provided, on which the stacks can be moved past the underside of the stack to cut through the banderoles.

Zuschnitte für Packungen werden vielfach in einem getrennten Arbeitsgang vorgefertigt und als Zuschnitt-Stapel der Verpackungsmaschine zur Verfügung gestellt. Diese Handhabung ist vor allem bei Zuschnitten für Klappschachteln (Hinge-Lid-Packungen) zur Aufnahme von Zigaretten üblich.Blanks for packs are often prefabricated in a separate operation and made available to the packaging machine as a stack of blanks. This handling is particularly common for blanks for hinged boxes (hinge-lid packs) to hold cigarettes.

Um den Zuschnitt-Stapeln einen besseren Halt zu geben, werden diese neuerdings vielfach mit einer Banderole aus Papier oder Folie versehen. Diese umgibt den Zuschnitt-Stapel aus langgestreckten, etwa rechteckigen Zuschnitten im Bereich von Längsseiten. Die Banderole muß vor der Verarbeitung der Zuschnitte beseitigt werden. Zu diesem Zweck wird die Banderole von Hand oder maschinell mit einem Trennmesser durchtrennt. Der von der Banderole befreite Zuschnitt-Stapel wird nun in ein Zuschnitt-Magazin der Verpackungsmaschine eingegeben.In order to give the stack of blanks a better hold, they are now often provided with a band made of paper or film. This surrounds the blank stack of elongated, approximately rectangular blanks in the area of the long sides. The band must be removed before processing the blanks. For this purpose, the band is cut by hand or by machine with a cutting knife. The stack of blanks freed from the banderole is now inserted into a blank magazine of the packaging machine.

Aus der EP-A-0 381 097 ist eine Vorrichtung zum Transport von durch Banderolen gehaltenen Stapeln gemäß dem Oberbegriff des Anspruchs 1 bekannt. Die Banderolen werden während einer relativen Transportbewegung des Stapels von einem ortsfesten Trennmesser durchtrennt.EP-A-0 381 097 discloses a device for transporting stacks held by banderoles according to the preamble of claim 1. The banderoles are cut by a stationary cutting knife during a relative transport movement of the stack.

Der Erfindung liegt die Aufgabe zugrunde, Maßnahmen vorzuschlagen, durch die ein Durchtrennen und Beseitigen der Banderolen auf einfache Weise und ohne Unterbrechung des Transportflusses für die Zuschnitt-Stapel sowie unter Einsatz einfacher maschinentechnischer Organe möglich ist.The invention has for its object to propose measures by which cutting and removing the banderoles in a simple manner and without interruption of the transport flow for the blank stack and using simple mechanical engineering organs is possible.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung durch folgende Merkmale gekennzeichnet:

  • c) der Stapelförderer ist ein Gurtförderer, auf dessen Fördergurt Stapel aus langgestreckten Zuschnitten aufliegen mit einer Förderrichtung quer zur Längserstreckung der Zuschnitte und mit einer Anordnung der Banderolen quer zur Längserstreckung der Zuschnitte,
  • d) seitlich neben dem Stapelförderer ist ein Zuschnitt-Magazin angeordnet,
  • e) zwischen dem Stapelförderer und dem Zuschnitt-Magazin ist das Trennmesser angeordnet, so daß die Banderolen während des Abschiebens der Zuschnitt-Stapel vom Stapelförderer in Richtung auf das Zuschnitt-Maganzin, d. h. in Richtung der Längserstreckung der Zuschnitte, durch das Trennmesser durchtrennbar sind.
To achieve this object, the device according to the invention is characterized by the following features:
  • c) the stack conveyor is a belt conveyor, on the conveyor belt of which lie stacks of elongated blanks with a conveying direction transverse to the longitudinal extension of the blanks and with an arrangement of the banderoles transverse to the longitudinal extension of the blanks,
  • d) a blank magazine is arranged to the side of the stacking conveyor,
  • e) the separating knife is arranged between the stacking conveyor and the blank magazine, so that the banderoles can be severed by the separating knife while the stack of blanks is being pushed off the stacking conveyor in the direction of the blanking magazine, ie in the direction of the longitudinal extent of the blanks.

Bei der Erfindung wird demnach der Vorgang des Durchtrennes der Banderole mit dem notwendigen Transport der Zuschnitt-Stapel zum Zuschnitt-Magazin in Einklang gebracht. Während eines Endabschnitts des Transports wird der Zuschnitt-Stapel an einem feststehenden Trennmesser vorbeibewegt, welches an der Unterseite des Zuschnitt-Stapels die Banderole durchtrennt. Die frei gewordene Banderole wird nach einer weiteren Ausgestaltung der Erfindung durch Absaugen beseitigt.In the invention, the process of severing the banderole is accordingly brought into line with the necessary transport of the blank stacks to the blank magazine. During an end section During transport, the stack of blanks is moved past a fixed cutting knife, which cuts the banderole on the underside of the stack of blanks. According to a further embodiment of the invention, the band which has become free is removed by suction.

Die Zuschnitt-Stapel werden durch einen als Bandförderer ausgebildeten Zuförderer angeliefert, und zwar mit ihrer Längserstreckung quer zur Förderrichtung. Von dem Zuförderer werden die Zuschnitt-Stapel durch einen als quergerichteten Magazin-Förderer wirkenden Schieber abgeschoben bis auf Tragorgane oberhalb des Zuschnitt-Magazins. Zwischen dem Zuförderer und dem Zuschnitt-Magazin ist das ortsfeste Trennmesser unterhalb der Bewegungsbahn der Zuschnitt-Stapel angeordnet.The stacks of blanks are delivered by a feed conveyor designed as a belt conveyor, with their longitudinal extension transverse to the conveying direction. The stack of blanks is pushed off the feed conveyor by a slide acting as a transverse magazine conveyor, except for the support members above the blank magazine. The stationary separating knife is arranged between the feed conveyor and the blank magazine below the movement path of the blank stack.

Die Tragorgane für die Zuschnitt-Stapel oberhalb des Zuschnitt-Magazins sind als in horizontaler Ebene bewegbare Tragplatten ausgebildet, die zur Einführung des Zuschnitt-Stapels in das Zuschnitt-Magazin auseinander bewegt werden.The support members for the stack of blanks above the blank magazine are designed as support plates which can be moved in the horizontal plane and which are moved apart for the introduction of the stack of blanks into the blank magazine.

Weiterhin ist von Bedeutung, daß die Zuschnitt-Stapel vor dem Abschieben von dem Zuförderer, also vor Durchführung des Trennschnitts, ausgerichtet werden durch Richtorgane, die an den Längsseiten des Zuschnitt-Stapels zur Anlage kommen.It is also important that the stack of blanks are aligned before being pushed off the feed conveyor, that is to say before the separating cut is carried out, by straightening members which come to rest on the long sides of the stack of blanks.

Ausgestaltungen der Erfindung beziehen sich auf konstruktive Einzelheiten der Förderer, des Trennmessers, der Richtorgane, der Tragplatten und von Absaugorganen.Refinements of the invention relate to structural details of the conveyors, the separating knife, the straightening members, the support plates and suction members.

Das in den Zeichnungen dargestellte Ausführungsbeispiel befaßt sich mit der Handhabung von Zuschnitten 10 zum Herstellen von Klappschachteln (Hinge-Lid-Packungen) für Zigaretten oder dergleichen. Zuschnitte 10 dieses Typs sind langgestreckt und annähernd rechteckig mit den für diese Packung typischen Konturen. Die Zuschnitte 10 werden in einer Verpackungsmaschine 11 verarbeitet, von der in Fig. 1 Teile schematisch dargestellt sind. Eine Mehrzahl von Zuschnitten 10 befindet sich für die Einzelentnahme in einem Zuschnitt-Magazin 12. Dieses wiederum besteht aus zwei nebeneinanderliegenden Magazin-Schächten 13 und 13a.The embodiment shown in the drawings deals with the handling of blanks 10 for the production of hinged boxes (hinge-lid packs) for cigarettes or the like. Blanks 10 of this type are elongated and approximately rectangular with the contours typical of this pack. The blanks 10 are processed in a packaging machine 11, parts of which are shown schematically in FIG. 1. A plurality of blanks 10 are located in a blank magazine 12 for individual removal. This in turn consists of two adjacent magazine shafts 13 and 13a.

Die Zuschnitte 10 werden übereinanderliegend als Zuschnitt-Stapel 14 angeliefert. Jeder Zuschnitt-Stapel 14 ist von einer Banderole 15 aus Papier oder einem anderen geeigneten Werkstoff umgeben. Die Banderole 15 befindet sich etwa im mittleren Bereich des Zuschnitt-Stapels 14 mit einer Oberwandung 16, Seitenwandungen 17 und 18 und einer Unterwandung 19. Die Seitenwandungen 17 und 18 erstrecken sich im Bereich von langgestreckten Seitenflächen 20 und 21 des Zuschnitt-Stapels 14.The blanks 10 are delivered one above the other as a blank stack 14. Each blank stack 14 is surrounded by a banderole 15 made of paper or another suitable material. The band 15 is located approximately in the central region of the blank stack 14 with an upper wall 16, side walls 17 and 18 and a lower wall 19. The side walls 17 and 18 extend in the region of elongated side surfaces 20 and 21 of the blank stack 14.

In dieser Weise ausgebildete Zuschnitt-Stapel 14 werden durch einen Zuförderer 22 angeliefert, der im vorliegenden Fall als Bandförderer ausgebildet ist. Die Zuschnitt-Stapel 14 sind in einer fortlaufenden Reihe mit geringen Abständen voneinander auf einem oberen Fördertrum des Zuförderers 22 gelagert, und zwar mit ihrer Längserstreckung quer zur Förderrichtung (in Fig. 1 von links nach rechts).Blank stacks 14 designed in this way are delivered by a feed conveyor 22, which in the present case is designed as a belt conveyor. The blank stack 14 are mounted in a continuous row with small distances from one another on an upper conveyor run of the feed conveyor 22, with their longitudinal extension transverse to the conveying direction (from left to right in FIG. 1).

Die Zuschnitt-Stapel 14 werden durch den Zuförderer 22 taktweise einem Hubförderer 23 übergeben. Dieser besteht bei dem vorliegenden Ausführungsbeispiel aus einer auf- und abbewegbaren Plattform 24. Diese nimmt jeweils einen Zuschnitt-Stapel 14 auf und transportiert ihn auf das Niveau eines anschließenden Stapelförderers 25. Dieser befindet sich auf einer Ebene, die das Einführen der Zuschnitt-Stapel 14 in das Zuschnitt-Magazin 12 von oben her ermöglicht.The blank stacks 14 are cyclically transferred by the feed conveyor 22 to a lifting conveyor 23. In the present exemplary embodiment, this consists of a platform 24 that can be moved up and down. This receives a blank stack 14 in each case and transports it to the level of a subsequent stack conveyor 25. This is located on a level that the insertion of the blank stack 14 allows in the blank magazine 12 from above.

Der Stapelförderer 25 ist hier ebenfalls ein Gurtförderer mit einem einzelnen Fördergurt 26, der eine Breite aufweist, die etwas geringer ist als die Länge der Zuschnitte 10 bzw. der Zuschnitt-Stapel 14. Diese werden an einem Aufgabeende einzeln, nacheinander durch ein hin- und herbewegbares Schuborgan 27 auf den Stapelförderer 25 aufgeschoben, derart, daß die aufeinanderfolgend transportierten Zuschnitt-Stapel 14 einen größeren Abstand voneinander aufweisen, nämlich etwa entsprechend dem Abstand der beiden Magazin-Schächte 13 und 13a voneinander. Der Stapelförderer 25 wird zu diesem Zweck mit entsprechend höherer Geschwindigkeit angetrieben.The stack conveyor 25 is here also a belt conveyor with a single conveyor belt 26, which has a width that is slightly less than the length of the blanks 10 or the blank stack 14. These are separated at one end of the task, one after the other by a back and forth Movable push member 27 pushed onto the stack conveyor 25 such that the successively transported blank stacks 14 are at a greater distance from one another, namely approximately according to the distance between the two magazine shafts 13 and 13a from one another. For this purpose, the stack conveyor 25 is driven at a correspondingly higher speed.

Die Zuschnitt-Stapel 14 werden durch den Stapelförderer 25 bis vor die Magazin-Schächte 13, 13a des Zuschnitt-Magazins 12 gefördert. Im Bereich einer Übergabestation 28 werden die Zuschnitt-Stapel 14 auf den zugeordneten Magazin-Schacht 13, 13a ausgerichtet und sodann quer zum Stapelförderer 25 in eine Position oberhalb einer Einfüllöffnung 29 des einen oder anderen Magazin-Schachts 13, 13a gefördert.The blank stacks 14 are conveyed by the stack conveyor 25 up to the magazine shafts 13, 13a of the blank magazine 12. In the area of a transfer station 28, the blank stacks 14 are aligned with the associated magazine chute 13, 13a and then conveyed transversely to the stack conveyor 25 into a position above a filling opening 29 of one or the other magazine chute 13, 13a.

Die Übergabe der Zuschnitt-Stapel 14 an die zugeordneten Magazin-Schächte 13, 13a erfolgt durch einen Querförderer, der die Zuschnitt-Stapel 14 vom Fördergurt 26 abschiebt und bis zur exakten Position über dem Magazin-Schacht 13, 13a fördert. Dieser Querförderer ist bei dem vorliegenden Ausführungsbeispiel ein Schieber 30, der den Zuschnitt-Stapel 14 im Bereich einer schmalen Seite, im vorliegenden Falle im Bereich von vorstehenden Kragen-Innenlappen 31 der Zuschnitte 10 erfaßt. Der Schieber 30 ist soweit querbewegbar, bis der Zuschnitt-Stapel 14 die in Fig. 4 gezeigte Position erreicht hat. Der Schieber 30 ist im vorliegenden Falle über einen Schieberarm 32 mit einem Antrieb oberhalb der Übergabestation 28 verbunden. Es handelt sich hier um einen langgestreckten Druckmittelzylinder 33 mit seitlich austretendem Ansatz 34 zur Verbindung mit dem Schieberarm 32 (Fig. 3).The blank stacks 14 are transferred to the assigned magazine shafts 13, 13a by a cross conveyor which pushes the blank stacks 14 off the conveyor belt 26 and conveys them to the exact position above the magazine shafts 13, 13a. In the present exemplary embodiment, this cross conveyor is a slide 30 which grips the blank stack 14 in the region of a narrow side, in the present case in the region of projecting inner collar tabs 31 of the blanks 10. The slider 30 can be moved transversely until the blank stack 14 has reached the position shown in FIG. 4. In the present case, the slide 30 is connected to a drive above the transfer station 28 via a slide arm 32. This is an elongated pressure medium cylinder 33 with a laterally emerging extension 34 for connection to the slide arm 32 (FIG. 3).

Auf der (kurzen) Transportstrecke des Zuschnitt-Stapels 14 vom Fördergurt 26 zum Magazin-Schacht 13, 13a wird die Banderole 15 durchtrennt, und zwar durch ein ortsfestes Trennmesser 35. Dieses ist im Bereich zwischen Stapelförderer 25 und Zuschnitt-Magazin 12 angeordnet. Das Trennmesser 35 wird an der Unterseite des Zuschnitt-Stapels 14 wirksam und durchtrennt hier etwa mittig die Banderole 15 (Fig. 6), also im Bereich der Unterwandung 19.The banderole 15 is severed on the (short) transport path of the blank stack 14 from the conveyor belt 26 to the magazine shaft 13, 13a, specifically by a stationary separating knife 35. This is arranged in the area between the stack conveyor 25 and the blank magazine 12. The separating knife 35 is effective on the underside of the blank stack 14 and cuts the band 15 (FIG. 6) approximately in the middle, that is to say in the region of the lower wall 19.

Das Trennmesser 35 ist in besonderer Weise ausgebildet, nämlich hakenförmig mit einer innenliegenden bzw. nach unten gerichteten Schneide 36. Das Trennmesser 35 bildet durch diese Gestalt einen innenliegenden Spalt bzw. Schlitz 37. In diesen tritt die Banderole 15, nämlich deren Untenwandung 19, während des Schneidvorgangs ein. Die Schneide 36 ist leicht schräggerichtet.The separating knife 35 is designed in a special way, namely hook-shaped with an internal or downward-facing cutting edge 36. The separating knife 35 forms an internal gap or slot 37 through this shape. The banderole 15, namely its bottom wall 19, enters this while of the cutting process. The cutting edge 36 is directed slightly obliquely.

Um einen zuverlässigen Trennschnitt zu gewährleisten, ist das Trennmesser 35 auf- und abbewegbar, bei dem vorliegenden Ausführungsbeispiel durch einen Kurzhub-Zylinder 38. Dieser ist so gesteuert, daß das Trennmesser 35 aus einer unteren Ausgangsstellung angehoben wird, sobald sich der Zuschnitt-Stapel 14 oberhalb des Trennmessers 35 befindet. Dieses wird sodann mit leichtem Druck gegen den unteren Zuschnitt 10 des Zuschnitt-Stapels 14 gedrückt. Dadurch wird ein gewisser Hohlraum zwischen dem Zuschnitt-Stapel 14 und der Unterwandung 19 der Banderole 15 gebildet. In diesem Bereich kann nun das Trennmesser 35 bei der Durchführung des Trennschnitts entlanggleiten, wobei der Zuschnitt-Stapel 14 relativ zum Trennmesser 35 bewegt wird.In order to ensure a reliable separating cut, the separating knife 35 can be moved up and down, in the present exemplary embodiment by a short-stroke cylinder 38. This is controlled in such a way that the separating knife 35 consists of one lower starting position is raised as soon as the blank stack 14 is above the separating knife 35. This is then pressed against the lower blank 10 of the blank stack 14 with slight pressure. As a result, a certain cavity is formed between the blank stack 14 and the bottom wall 19 of the band 15. In this area, the cutting knife 35 can now slide along when performing the cutting cut, the blank stack 14 being moved relative to the cutting knife 35.

Der Zuschnitt-Stapel 14 gelangt mit der durchtrennten Banderole 15 in den Bereich oberhalb des Magazin-Schachts 13, 13a. Hier wird die Banderole 15 durch (zwei) Sauger 39 erfaßt, und zwar im Bereich der Oberwandung 16. Bei der anschließenden Absenkbewegung des Zuschnitt-Stapels 14 in den Magazin- Schacht 13, 13a wird die Banderole 15 von den Saugern 39 weiterhin gehalten und kommt dadurch von dem Zuschnitt-Stapel 14 frei.The cut stack 14 reaches with the severed banderole 15 in the area above the magazine chute 13, 13a. Here, the banderole 15 is gripped by (two) suction devices 39, specifically in the region of the upper wall 16. During the subsequent lowering movement of the stack of blanks 14 into the magazine chute 13, 13a, the banderole 15 is still held by the suction devices 39 and comes thereby free from the blank stack 14.

Zur vollständigen Beseitigung der Banderole 15 wird diese abgefördert, und zwar abgesaugt. Zu diesem Zweck mündet ein ausreichend dimensionierter Saugkanal 40 im Bereich oberhalb des Magazin- Schachts 13, 13a. Jeder Saugkanal 40 ist mit einer Unterdruckquelle verbunden und führt zu einem gemeinsamen Sammelbehälter, nämlich einem Sack 41, zur Aufnahme der Banderolen 15. Der Saugkanal 40 wird jeweils an einer Seitenwandung 17 bzw. 18 der Banderole 15 wirksam. Diese wird durch den Unterdruck in den Saugkanal 40 gezogen und in den Sack 41 gefördert.To completely remove the banderole 15, it is removed and sucked off. For this purpose, a sufficiently dimensioned suction channel 40 opens in the area above the magazine chute 13, 13a. Each suction channel 40 is connected to a vacuum source and leads to a common collecting container, namely a sack 41, for receiving the banderoles 15. The suction channel 40 is effective on a side wall 17 and 18 of the banderole 15, respectively. This is drawn into the suction channel 40 by the negative pressure and conveyed into the bag 41.

Um einen präzisen Transport der Zuschnitt-Stapel 14 im Bereich der Übergabestation 28 zu gewährleisten, wird jeder Zuschnitt-Stapel 14 auf dem Stapelförderer 25 ausgerichtet. Hierzu sind plattenförmige Ausrichter 42, 43 vorgesehen, die an den langgestreckten Seitenflächen 20, 21 des Zuschnitt-Stapels 14 Anlage erhalten. Die Breite der Ausrichter 42, 43 ist nur geringfügig kleiner als die Länge der Zuschnitt-Stapel 14.In order to ensure a precise transport of the blank stacks 14 in the area of the transfer station 28, each blank stack 14 is aligned on the stack conveyor 25. For this purpose, plate-shaped aligners 42, 43 are provided, which are attached to the elongated side surfaces 20, 21 of the blank stack 14. The width of the aligners 42, 43 is only slightly smaller than the length of the blank stack 14.

Die Ausrichter 42, 43 haben vorrangig die Aufgabe, den Zuschnitt-Stapel 14 exakt auf die Einfüllöffnung 29 des Magazin-Schachts 13 oder 13a auszurichten, so daß eine geradlinige Querbewegung zu einer genauen Positionierung des Zuschnitt-Stapels 14 über der jeweiligen Einfüllöffnung 29 führt. Die Ausrichter 42, 43 sind zu diesem Zweck schwenkbar gelagert, und zwar jeweils in einem oberhalb des Zuschnitt-Stapels 14 gebildeten Drehlager. Dieses besteht bei dem vorliegenden Ausführungsbeispiel aus einer in Längsrichtung des Zuschnitt-Stapels 14 liegenden Drehstange 44, 45. Die Enden der Drehstange 44, 45 sind drehbar in ortsfesten Halterungen des Maschinengestells gelagert. Ein Betätigungsorgan, nämlich ein Betätigungszylinder 46, 47, ist über einen quergerichteten Hebel 48 mit der Drehstange 44, 45 verbunden. Hin- und hergehende Drehbewegungen werden so durch den Betätigungszylinder 46, 47 auf die Ausrichter 42, 43 übertragen.The aligners 42, 43 primarily have the task of aligning the blank stack 14 exactly with the filling opening 29 of the magazine shaft 13 or 13a, so that a straight transverse movement leads to an exact positioning of the blank stack 14 over the respective filling opening 29. For this purpose, the aligners 42, 43 are pivotably mounted, in each case in a rotary bearing formed above the blank stack 14. In the present exemplary embodiment, this consists of a rotating rod 44, 45 lying in the longitudinal direction of the blank stack 14. The ends of the rotating rod 44, 45 are rotatably mounted in stationary mounts of the machine frame. An actuating member, namely an actuating cylinder 46, 47, is connected to the rotary rod 44, 45 via a transverse lever 48. Back and forth rotary movements are thus transmitted to the aligners 42, 43 by the actuating cylinders 46, 47.

Die Arbeitsweise der Ausrichter 42, 43 ist so eingerichtet, daß ein auf dem Stapelförderer 25 ankommender Zuschnitt-Stapel 14 gegen den in Förderrichtung zweiten Ausrichter 43 läuft. Dieser befindet sich demnach in der aufrechten Position und dient als Anschlag für den ankommenden Zuschnitt-Stapel 14. Der andere, in Förderrichtung erste Ausrichter 42 befindet sich während dieser Phase in einer oberen bzw. horizontalen Position (strichpunktiert in Fig. 5). Der Zuschnitt-Stapel 14 kann demnach ungehindert an diesem Ausrichter 42 vorbeilaufen.The mode of operation of the aligners 42, 43 is set up in such a way that a blank stack 14 arriving on the stack conveyor 25 runs against the second aligner 43 in the conveying direction. Accordingly, this is in the upright position and serves as a stop for the incoming blank stack 14. The other aligner 42, which is the first in the conveying direction, is in an upper or horizontal position during this phase (dash-dotted lines in FIG. 5). The blank stack 14 can therefore pass this aligner 42 unhindered.

Nach Anlage eines Zuschnitt-Stapels 14 an dem Ausrichter 43 wird der Ausrichter 42 in die untere bzw. aufrechte Ausrichtposition (Fig. 5) bewegt. Beide Ausrichter 42, 43 erhalten dabei Anlage an den Seitenflächen 20, 21, und zwar über die volle Höhe des Zuschnitt-Stapels 14. Dieser wird dabei auch hinsichtlich der Relativstellung der einzelnen Zuschnitte 10 vor der Übergabe an das Zuschnitt-Magazin 12 ausgerichtet.After a stack of blanks 14 has been placed on the aligner 43, the aligner 42 is moved into the lower or upright alignment position (FIG. 5). Both aligners 42, 43 receive contact on the side surfaces 20, 21, namely over the full height of the blank stack 14. This is also aligned with respect to the relative position of the individual blanks 10 before transfer to the blank magazine 12.

Für den Abtransport des Zuschnitt-Stapels 14 zum Zuschnitt-Magazin 12 werden beide Ausrichter 42, 43 von den Seitenflächen 20, 21 des Zuschnitt-Stapels 14 zurückgezogen.For the removal of the blank stack 14 to the blank magazine 12, both aligners 42, 43 are withdrawn from the side surfaces 20, 21 of the blank stack 14.

Die Übergabestationen 28 für die beide Magazin-Schächte 13, 13a werden durch den gemeinsamen Stapelförderer 25 versorgt. Die Übergabestationen 28 sind in Förderrichtung nacheinander gebildet. Wenn die in Förderrichtung zweite Übergabestation 28 beschickt werden soll (Magazin-Schacht 13a) werden beide Ausrichter 42, 43 des Magazin-Schachts 13 aus der Bewegungsbahn der Zuschnitt-Stapel 14 herausbewegt, nämlich durch Verschwenken, so daß der betreffende Zuschnitt-Stapel 14 zu der in Förderrichtung zweiten Übergabestation 28 transportiert werden kann.The transfer stations 28 for the two magazine shafts 13, 13a are supplied by the common stacking conveyor 25. The transfer stations 28 are formed one after the other in the conveying direction. If the second transfer station 28 is to be loaded in the conveying direction (magazine shaft 13a), both aligners 42, 43 of the magazine shaft 13 are moved out of the movement path of the blank stack 14, namely by pivoting, so that the blank stack 14 in question is closed which can be transported in the conveying direction of the second transfer station 28.

Der als aufrechter Steg ausgebildete Schieber 30 wird im Bereich einer besonderen Gestaltung des Fördergurts 26 des Stapelförderers 25 wirksam. Der Fördergurt 26 wird in diesem Bereich über drei Umlenkrollen 49, 50, 51 geführt. Die mittlere Umlenkrolle 51 liegt unterhalb der oberen Umlenkrollen 49, 50. Es wird dadurch eine Schleife im Fördergurt 26 gezogen. Diese wiederum bewirkt einen Spalt 52 in der oberen Transportebene für die Zuschnitt-Stapel 14. Der Schieber 30 wird im Bereich dieses Spalts 52 wirksam und kann dadurch den Zuschnitt-Stapel 14 zuverlässig über die gesamte Höhe erfassen bzw. unten geringfügig über den Zuschnitt-Stapel 14 hinwegragen (Fig. 5).The slider 30 designed as an upright web is effective in the area of a special configuration of the conveyor belt 26 of the stacking conveyor 25. The conveyor belt 26 is guided in this area over three deflection rollers 49, 50, 51. The middle deflection roller 51 lies below the upper deflection rollers 49, 50. A loop is thereby drawn in the conveyor belt 26. This in turn creates a gap 52 in the upper transport plane for the blank stack 14. The slider 30 is effective in the area of this gap 52 and can thereby reliably detect the blank stack 14 over the entire height or slightly below the blank stack 14 protrude (Fig. 5).

Im Bereich des Zuschnitt-Magazins 12 bzw. der Magazin-Schächte 13, 13a sind oberhalb der Einfüllöffnungen 29 Seitenführungen 53, 54 ortsfest als Teil des Maschinengestells gebildet. Die Seitenführungen 53, 54 zu beiden Seiten jeder Einfüllöffnung 29 nehmen in einer Ausnehmung Tragorgane für den in den Magazin-Schacht 13, 13a einzuführenden Zuschnitt-Stapel 14 auf. Es handelt sich dabei um zu beiden Seiten der Einfüllöffnung 29 angeordnete Tragschenkel 55, 56. Diese dienen zur zeitweiligen Auflage eines Zuschnitt-Stapels 14 exakt über der Einfüllöffnung 29. Die Tragschenkel 55, 56 erfassen den Zuschnitt-Stapel 14 an der Unterseite im Bereich von Längsrändern des jeweils unteren Zuschnitts 10.In the region of the blank magazine 12 or the magazine shafts 13, 13a, 29 side guides 53, 54 are formed in a stationary manner above the filling openings as part of the machine frame. The side guides 53, 54 on both sides of each fill opening 29 receive in a recess supporting members for the blank stack 14 to be inserted into the magazine shaft 13, 13a. These are support legs 55, 56 arranged on both sides of the filling opening 29. These serve for temporary support a stack of blanks 14 exactly above the filling opening 29. The support legs 55, 56 grip the stack of blanks 14 on the underside in the region of longitudinal edges of the respective lower blank 10.

Die Tragschenkel 55, 56 sind an seitlichen Tragorganen angebracht, nämlich an Haltewänden 57, 58. Die Tragschenkel 55, 56 sind zur Übergabe eines Zuschnitt-Stapels 14 an einen Magazin-Schacht 13, 13a querbewegbar, und zwar in der Ebene der unteren Begrenzung des Zuschnitt-Stapels 14. Zu diesem Zweck sind im vorliegenden Falle die Haltewände 57, 58 oberhalb der Magazin-Schächte 13, 13a verschiebbar gelagert. Ein quergerichtetes Haltestück 59, 60 ist auf zwei im Abstand voneinander angeordneten Tragstangen 61, 62 verschiebbar gelagert. Die Tragschenkel 55, 56 können dadurch - mit den Haltewänden 57, 58 - in Richtung zueinander bewegt werden in eine Tragposition (Fig. 6) und auseinander in eine Stellung, in der die Einfüllöffnung 29 freigegeben ist.The support legs 55, 56 are attached to lateral support members, namely on retaining walls 57, 58. The support legs 55, 56 are transversely movable for transferring a stack of blanks 14 to a magazine slot 13, 13a, in the plane of the lower limit of the Blank stack 14. For this purpose, the holding walls 57, 58 are slidably mounted above the magazine shafts 13, 13a in the present case. A transverse holding piece 59, 60 is slidably supported on two spaced-apart support rods 61, 62. The support legs 55, 56 can thereby - with the retaining walls 57, 58 - be moved in the direction of one another into a carrying position (FIG. 6) and apart into a position in which the filling opening 29 is opened.

Die Betätigung der Tragschenkel 55, 56 über die Haltewände 57, 58 und die Haltestücke 59, 60 erfolgt mit einem gemeinsamen Stellzylinder 63. Dieser ist im vorliegenden Falle unmittelbar mit einem Haltestück 60 verbunden. Dieses wird demnach durch den Stellzylinder 63 unmittelbar auf den Tragstangen 61, 62 hin- und herbewegt. Diese Bewegung wird über ein Verbindungsgetriebe mit gegenläufiger Richtung auf das andere Haltestück 59 und damit auf den anderen Tragschenkel 55 übertragen. Das Verbindungsgetriebe besteht hier aus den Lenkern 64 und 65 sowie einem in der Mitte angeordneten zentralen Drehstück 66. Letzteres ist auf einem Verbindungsstück 67 für die beiden Tragstangen 61, 62 mittig oberhalb der Einfüllöffnung 29 drehbar gelagert. Die Lenker 64, 65 sind schwenkbar auf gegenüberliegenden Seiten einer Drehachse des Drehstücks 66 mit diesem verbunden. Dadurch kommt es zu einer exakten, aufeinander abgestimmten und gegenläufigen Bewegung der Tragschenkel 55, 56 aufgrund der Betätigung durch einen gemeinsamen Stellzylinder 63.The actuation of the support legs 55, 56 via the holding walls 57, 58 and the holding pieces 59, 60 takes place with a common actuating cylinder 63. In the present case, this is connected directly to a holding piece 60. Accordingly, this is moved back and forth by the actuating cylinder 63 directly on the support rods 61, 62. This movement is transmitted via a connecting gear in the opposite direction to the other holding piece 59 and thus to the other support leg 55. The connecting gear consists here of the links 64 and 65 and a central rotating piece 66 arranged in the middle. The latter is rotatably mounted on a connecting piece 67 for the two supporting rods 61, 62 centrally above the filling opening 29. The links 64, 65 are pivotally connected to the rotating piece 66 on opposite sides of an axis of rotation thereof. This results in an exact, coordinated and opposite movement of the support legs 55, 56 due to the actuation by a common actuating cylinder 63.

Der Saugkanal 40 tritt bei dem vorliegenden Beispiel durch die eine Haltewand 57 im Bereich einer Ausnehmung 68 hindurch.In the present example, the suction channel 40 passes through the one holding wall 57 in the region of a recess 68.
