Description

Die Erfindung betrifft eine Einrichtung zum automatischen Befüllen eines im wesentlichen vertikalen Magazinschachtes zur Aufnahme eines Stapels von Kartonzuschnitten, insbesondere für Zigarettenpäckchen, aus dem die Kartonzuschnitte bodenseitig entnehmbar sind, mit einem Förderer, der mit seinem Abgabeende am Magazinschacht endet und eine horizontale Förderstrecke zur Aufnahme von mehreren Vorratsstapeln von Kartonzuschnitten aufweist sowie mit einem Antrieb versehen ist, der über einen Abtaster für die Oberkante des im Magazinschacht befindlichen Stapels einschaltbar und nach Positionierung eines Vorratsstapels im Bereich des Magazinschachtes abschaltbar ist, und mit einer in den Bereich des Magazinschachtes von einer Seite einschwenkbaren Auflage für einen vom Förderer in den Bereich des Magazinschachtes beförderten Vorratsstapel.The invention relates to a device for automatically filling a substantially vertical magazine shaft for receiving a stack of cardboard blanks, in particular for cigarette packs, from which the cardboard blanks can be removed on the bottom, with a conveyor which ends at the discharge end of the magazine shaft and a horizontal conveyor line for receiving has several stacks of cardboard blanks and is provided with a drive that can be switched on via a scanner for the upper edge of the stack located in the magazine shaft and can be switched off after positioning a stack of stacks in the area of the magazine shaft, and with a support that can be pivoted into the area of the magazine shaft from one side for a stack of supplies carried by the conveyor into the area of the magazine shaft.

In der Verpackungsindustrie werden Magazine zur Aufnahme von Kartonzuschnitten in Stapelform verwendet, die nach Entnahme aus dem Magazin in entsprechenden Verpackungslinien um zu verpackende Gegenstände gefaltet werden. Das Füllen der Magazine erfolgt üblicherweise manuell, indem ein Stapel von Kartonzuschnitten aus einem entsprechenden Vorrat entnommen und in das Magazin eingelegt wird. Da die Verpackungsgeschwindigkeiten jedoch sehr hoch sind und die Magazinschächte nicht beliebig hoch gemacht werden können, ist ein sehr häufiges Nachfüllen erforderlich, wodurch die Bedienungsperson stark beansprucht wird, obwohl gewöhnlich auch noch andere Nachfüll- bzw. Verpackungsvorgänge von der Bedienungsperson vorzunehmen bzw. zu beobachten sind. Daher kann es häufiger passieren, daß ein derartiges Magazin leer läuft, wodurch die gesamte Verpackungslinie zum Stillstand kommt.In the packaging industry, magazines are used to hold cardboard blanks in stack form, which, after removal from the magazine, are folded into corresponding packaging lines around objects to be packed. The magazines are usually filled manually by taking a stack of cardboard blanks from a corresponding supply and inserting them into the magazine. However, since the packaging speeds are very high and the magazine chutes cannot be made arbitrarily high, a very frequent refilling is required, which places a great strain on the operator, although other refilling or packaging processes are usually also to be carried out or observed by the operator . It can therefore happen more often that such a magazine runs empty, causing the entire packaging line to come to a standstill.

Aus der DE-C-2 423 885 ist bereits eine Einrichtung der eingangs genannten Art bekannt, bei der die jeweiligen Stapel aus Kartonzuschnitten mittels entsprechender Organe horizontal und vertikal geführt werden, die komplizierte und aufeinander abgestimmte Betätigungsmechanismen erfordern, so daß die Konstruktion dementsprechend aufwendig ist und einen entsprechend großen Raumbedarf erfordert.From DE-C-2 423 885 a device of the type mentioned is already known, in which the respective stacks of cardboard blanks are guided horizontally and vertically by means of corresponding organs that require complicated and coordinated actuation mechanisms, so that the construction is correspondingly complex and requires a correspondingly large amount of space.

Aus der US-A-4 046 370 ist eine Einrichtung zum automatischen Befüllen eines Magazinschachtes zur Aufnahme eines Stapels von Prospekteinlagen für Zeitungen bekannt, wobei ein Vorratsstapel auf einem Förderband plaziert und mit diesem auf eine hin- und herbewegliche Auflageplatte befördert wird, von der der Stapel um eine ganze Stapelhöhe in den Magazinschacht fällt. Beim Wegziehen der Auflageplatte biegen sich dabei die Zeitungseinlagen nach einer Seite hin abwärts, was insbesondere bei der vorgesehenen Fallhöhe zu Störungen und damit Maschinenstillständen führen kann.From US-A-4 046 370 a device for the automatic filling of a magazine slot for receiving a stack of brochure inserts for newspapers is known, wherein a stack of stocks is placed on a conveyor belt and is transported with it to a reciprocating platen, from which the Stack falls into the magazine slot by an entire stack height. When the platen is pulled away, the newspaper inserts bend downwards to one side, which can lead to malfunctions and machine downtimes, especially when the height of fall is envisaged.

Aufgabe der Erfindung ist es daher, eine Einrichtung zum automatischen Befüllen eines Magazinschachtes der eingangs genannten Art zu schaffen, die konstruktiv einfach ist.The object of the invention is therefore to provide a device for automatically filling a magazine shaft of the type mentioned, which is structurally simple.

Diese Aufgabe wird dadurch gelöst, daß der Magazinschacht an der dem Abgabeende des Förderers benachbarten Seite durch eine am Abgabeende beginnende Führungswand und auf der gegenüberliegenden Seite durch eine um mindestens die Stapelhöhe über das Abgabeende hochragende Wand begrenzt ist, wobei der Abtaster in einer Höhe geringfügig unter der horizontalen Förderstrecke des Förderers angeordnet ist, die Auflage und eine weitere, von der anderen Seite einschwenkbare Auflage quer zur Förderrichtung des Förderers verschwenkbar sind und die Auflagen nach Erreichen der hochragenden Wand durch einen vom Förderer in den Bereich des Magazin- schachtes geförderten Vorratsstapel aus dem Bereich des Magazinschachtes herausschwenkbar sind.This object is achieved in that the magazine shaft is delimited on the side adjacent to the discharge end of the conveyor by a guide wall beginning at the discharge end and on the opposite side by a wall which rises above the discharge end by at least the stack height, the scanner being slightly below in height the horizontal conveying path of the conveyor is arranged, the support and a further support which can be swiveled in from the other side can be pivoted transversely to the conveying direction of the conveyor and the supports after reaching the towering wall by a stack of stock conveyed by the conveyor into the area of the magazine shaft Area of the magazine shaft can be swung out.

Hierdurch ist es möglich, einen größeren Vorrat an Kartonzuschnitten für den Magazinschacht bereitzustellen und bei Bedarf in diesen automatisch einzufüllen, so daß eine Bedienungsperson dem Füllstand des Magazinschachtes bzw. dem verfügbaren Zuschnittvorrat weit weniger Aufmerksamkeit zu schenken braucht und dann Zeit hat, sich anderen Aufgaben zu widmen. Außerdem ist die Einrichtung konstruktiv einfach und ohne Aufwand mit einem üblichen Magazinschacht zu koppeln. Insbesondere ist eine derartige Einrichtung für Zigarettenverpackungsmaschinen und die dabei verwendeten Magazinschächte geeignet.This makes it possible to provide a larger supply of cardboard blanks for the magazine shaft and to fill them automatically if necessary, so that an operator needs to pay far less attention to the filling level of the magazine shaft or the available blank supply and then has time to do so to devote to other tasks. In addition, the device is structurally simple and easy to couple with a conventional magazine shaft. Such a device is particularly suitable for cigarette packaging machines and the magazine shafts used in the process.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand des in der beigefügten Abbildung schematisch dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to the embodiment shown schematically in the accompanying figure.

Der dargestellte Magazinschacht 1 ist in dem Ausführungsbeispiel als Doppelmagazinschacht mit einer vertikalen Mittelwand 2 und mit Abstand entsprechend der Breite von aufzunehmenden Kartonzuschnitten 3 dazu angeordneten, vertikalen, seitlichen Führungen 4 versehen. Die Mittelwand 2 und die seitlichen Führungen 4 besitzen am unteren Entnahmeende des Magazinschachtes 1 Unterstützungskanten 5 für den jeweiligen Stapel 6 von Kartonzuschnitten 3. Außerdem sind frontseitig sich vertikal erstreckende Führungen 7 mit Abstand zwischen der Mittelwand 2 und den seitlichen Führungen 4 vorgesehen, während rückseitig eine Rückwand 8 vorgesehen ist, die auch durch den Maschinenrahmen der Verpackungsmaschine, für die der Magazinschacht gebraucht wird, gebildet werden kann. Auf diese Weise wird der Magazinschacht 1 gebildet, der den Stapel 6 aufnimmt, aus dem die Entnahme der Kartonzuschnitte 3 bodenseitig erfolgt, in dem die Kartonzuschnitte 3 unter Schwerkrafteinwirkung entsprechend der Entnahme nachrutschen und der von oben nachzufüllen ist.The illustrated magazine shaft 1 is provided in the exemplary embodiment as a double magazine shaft with a vertical middle wall 2 and vertical, lateral guides 4 arranged at a distance corresponding to the width of cardboard blanks 3 to be accommodated. The middle wall 2 and the side guides 4 have at the lower removal end of the magazine shaft 1 support edges 5 for the respective stack 6 of cardboard blanks 3. In addition, vertically extending guides 7 are provided on the front at a distance between the middle wall 2 and the side guides 4, while on the back one Rear wall 8 is provided, which can also be formed by the machine frame of the packaging machine for which the magazine shaft is used. In this way, the magazine shaft 1 is formed, which receives the stack 6, from which the carton blanks 3 are removed from the bottom, in which the carton blanks 3 slide under the action of gravity in accordance with the removal and which has to be refilled from above.

Benachbart zum Magazinschacht 1 ist an jeder Seite hiervon ein horizontaler Gurtförderer 9 angeordnet, der einen um Rollen 10 geführten Gurt 11 aufweist, wobei eine der Rollen 10 über einen Motor 12 und eine Kupplung 13 antreibbar ist. Der Obertrum des Gurtes 11 läuft über eine Unterstützungsplatte 14. Die seitliche Führung 4 endet im wesentlichen tangential zum Gurt 11 bzw. der Rolle 10, die sich benachbart zum Magazin 1 befindet, so daß ein vom Gurtförderer 9 zugeführter Vorratsstapel 6' am Gurt 11 und einer Abschrägung 15 der Führung 4 entlang in den Magazinschacht 1 rutscht.Adjacent to the magazine shaft 1, a horizontal belt conveyor 9 is arranged on each side thereof, which has a belt 11 guided around rollers 10, one of the rollers 10 being drivable via a motor 12 and a clutch 13. The upper run of the belt 11 runs over a support plate 14. The lateral guide 4 ends essentially tangentially to the belt 11 or the roll 10, which is located adjacent to the magazine 1, so that a stack of stock 6 'fed by the belt conveyor 9' on the belt 11 and a bevel 15 slides along the guide 4 into the magazine shaft 1.

Die Rückwand 8 des Magazinschachtes 1 erstreckt sich auch über die Länge des Gutförderers 9 mit einer Höhe mindestens entsprechend einer vorgesehenen maximalen Stapelhöhe oberhalb des Obertrums des Gurtes 11. Dementsprechend können Vorratsstapel 6', 6'' von einer Bedienungsperson auf dem Gurt 11 nebeneinander gestapelt werden, wobei die Vorratsstapel 6', 6'' durch Andrücken gegen die Rückwand 8 entsprechend zum Magazinschacht 1 ausgerichtet werden.The rear wall 8 of the magazine shaft 1 also extends over the length of the material conveyor 9 with a height at least corresponding to an intended maximum stack height above the upper strand of the belt 11. Accordingly, an operator can stack stacks 6 ', 6' 'on the belt 11 side by side , the supply stacks 6 ', 6' 'being aligned with the magazine shaft 1 by pressing against the rear wall 8.

Vorderseitig besitzt der Magazinschacht 1 in seinem oberen Bereich ebenfalls eine Wandung 16, die sich etwa von der Höhe des Untertrums des Gurtes 11 bis zur Höhe der Oberkante der Rückwand 8 und über die Magazinschachtbreite erstreckt, so daß sie zusammen mit der Mittelwand 2 und der Rückwand 8 einen zum Gurtförderer 9 hin offenen Schacht bildet, dessen Größe derart ist, daß ein Vorratsstapel 6' hiervon aufgenommen werden kann.On the front side, the magazine shaft 1 also has a wall 16 in its upper region, which extends approximately from the height of the lower run of the belt 11 to the height of the upper edge of the rear wall 8 and over the width of the magazine shaft, so that it together with the middle wall 2 and the rear wall 8 forms a shaft open to the belt conveyor 9, the size of which is such that a supply stack 6 'can be received therefrom.

In Höhe des Obertrums des Gurtes 11 sind die beiden im wesentlichen im Abstand einer Stapelbreite angeordneten Wandungen 8, 16 mit einem waagerechten Schlitz 17 versehen, während außenseitig auf den Wandungen 8, 16 jeweils Lagerbuchsen 18 für eine Welle 19 angeordnet sind. Die beiden Wellen 19 tragen jeweils einen Hebel 20. Die beiden Hebel 20 besitzen am freien Ende Auflageplatten 21, die durch die Schlitze 17 in das Innere des Magazinschachtes 1 eintauchen können und sich jeweils über einen Teil der Schachttiefe, beispielsweise über ein Drittel hiervon erstrecken. Die Wellen 19 sind über einen entsprechenden (nicht dargestellten) Antrieb hin- und herdrehbar, um die Auflageplatten 21 in den Magazinschacht 1 bzw. wieder aus diesem heraus zu schwenken. Im eingeschwenkten Zustand der Auflageplatten 21 bilden diese eine Auflage für einen Vorratsstapel 6' aus Kartonzuschnitten 3 in Höhe des Obertrums des Gurtes 11, so daß vom Gurt 11 ein Vorratsstapel 6' auf die Auflageplatten 21 gefördert werden kann. Durch Ausschwenken der Auflageplatten 21 aus dem Magazinschacht 1 fällt der darauf befindliche Vorratsstapel 6' vertikal und ausgerichtet auf den bereits im Magazinschacht 1 befindlichen Stapel 6.At the height of the upper run of the belt 11, the two walls 8, 16 arranged essentially at a distance from one another are provided with a horizontal slot 17, while bearing bushes 18 for a shaft 19 are arranged on the outside of the walls 8, 16. The two shafts 19 each carry a lever 20. The two levers 20 have support plates 21 at the free end, which can penetrate through the slots 17 into the interior of the magazine shaft 1 and each extend over part of the shaft depth, for example over a third thereof. The shafts 19 can be rotated back and forth via a corresponding drive (not shown) in order to pivot the support plates 21 into the magazine shaft 1 or out of it again. In the pivoted-in state of the support plates 21, these form a support for a supply stack 6 'of cardboard blanks 3 at the height of the upper run of the belt 11, so that a supply stack 6' can be conveyed onto the support plates 21 by the belt 11. By swiveling the support plates 21 out of the magazine shaft 1, the supply stack 6 ′ located thereon falls vertically and aligned onto the stack 6 already located in the magazine shaft 1.

Ein optischer Abtaster 22 ist in einer Höhe geringfügig unterhalb der Höhe des Obertrums des Gurtes 11 derart angeordnet, daß er feststellen kann, ob die Oberkante 23 des im Magazinschacht 1 befindlichen Stapels 6 unter die Höhe des optischen Abtasters 22 gefallen ist oder nicht. Der optische Abtaster 22 ist mit dem Motor 12 gekoppelt und setzt diesen in Gang, wenn ersteres der Fall ist. Hierdurch werden die auf dem Gurtförderer 9 befindlichen Vorratsstapel 6', 6'' in Richtung zur Mittelwand 2 des Magazinschachtes 1 auf die Auflageplatten 21 befördert und der Vorratsstapel 6' gelangt schließlich in Anlage an die Mittelwand 2 sowie nach Zurückziehen der Auflageplatten 21 aus dem Magazinschacht 1 auf den im Magazinschacht 1 befindlichen Stapel 6.An optical scanner 22 is arranged at a height slightly below the height of the upper run of the belt 11 such that it can determine whether the upper edge 23 of the stack 6 located in the magazine shaft 1 has fallen below the height of the optical scanner 22 or not. The optical scanner 22 is coupled to the motor 12 and starts it when the former is the case. As a result, the supply stacks 6 ′, 6 ″ located on the belt conveyor 9 are conveyed in the direction of the central wall 2 of the magazine shaft 1 onto the support plates 21 and the supply stack 6 ′ finally comes into contact with the central wall 2 and after the support plates 21 have been withdrawn from the magazine shaft 1 on the stack 6 located in the magazine shaft 1.

Der Motor 12 kann über ein Zeitglied ansteuerbar sein, dessen Zeitkonstante derart bemessen ist, daß der Vorratsstapel 6' bis zur Mittelwand 2 befördert wird. Stattdessen kann aber auch ein weiterer optischer Abtaster 24 feststellen, ob der Vorratsstapel 6' die Mittelwand 2 erreicht hat und in diesem Moment den Motor 12 abschalten.The motor 12 can be controlled via a timing element, the time constant of which is dimensioned such that the supply stack 6 'is conveyed up to the middle wall 2. Instead, another optical scanner 24 can also determine whether the supply stack 6 'has reached the middle wall 2 and switch off the motor 12 at this moment.

Da zwischen den Vorratsstapeln 6', 6'' unterschiedlich große Abstände bestehen können, da die Vorratsstapel 6', 6'' manuell auf den Gurtförderer 9 aufgelegt werden, ist es zweckmäßig, den Motor 12 über das eine Zeitglied solange zu betreiben, bis der mögliche Abstand zum nächsten Vorratsstapel 6'' überwunden ist, um dann den Motor 12 über ein zweites Zeitglied in umgekehrter Richtung anzutreiben, damit der Vorratsstapel 6'' in eine definierte Ausgangsstellung zurückgeführt wird.Since there can be different distances between the supply stacks 6 ', 6' ', since the supply stacks 6', 6 '' are manually placed on the belt conveyor 9, it is expedient to operate the motor 12 via the one timing element until the possible distance to the next supply stack 6 ″ has been overcome, in order to then drive the motor 12 in the opposite direction via a second timing element, so that the supply stack 6 ″ is returned to a defined starting position.

Stattdessen kann auch ein weiterer optischer Abtaster 25 für den Zwischenraum zwischen den Vorratsstapeln 6', 6'' vorgesehen sein, der dazu dient, dann, wenn der optische Abtaster 24 anzeigt, daß der Vorratsstapel 6' die Mittelwand 2 erreicht hat, den Motor 12 erst dann anzuhalten, wenn der nächste Vorratsstapel 6'' sein Gesichtsfeld erreicht hat.Instead, a further optical scanner 25 can also be provided for the space between the supply stacks 6 ′, 6 ″, which is used when the optical scanner 24 indicates that the supply stack 6 ′ has reached the middle wall 2, the motor 12 only stop when the next stack of 6 '' has reached its field of vision.

Da die Entnahme der Kartonzuschnitte 3 aus dem Magazin 1 mit sehr hoher Geschwindigkeit erfolgen kann (mehrere hundert pro Minute), wird hierdurch sichergestellt, daß die von dem in den Magazinschacht 1 geförderten Vorratsstapel 6' zu überwindende Fallhöhe, über die sich die Wandung 16 zweckmäßigerweise mindestens nach unten erstreckt, bis zum Erreichen der Oberkante 23 des Stapels 6 minimal gehalten wird, damit Störungen vermieden werden.Since the removal of the cardboard blanks 3 from the magazine 1 can take place at a very high speed (several hundred per minute), this ensures that the drop height to be overcome by the stack 6 'conveyed into the magazine shaft 1, via which the wall 16 expediently extends extends at least downwards until the upper edge 23 of the stack 6 is kept to a minimum so that faults are avoided.

Außerdem kann ein weiterer optischer Abtaster 26 in dem Bereich, in dem sich normalerweise ein Vorratsstapel 6' in Wartestellung zum Hineinfördern in den Magazinschacht 1 befindet, angeordnet sein, der bei fehlendem Vorratsstapel 6' ein akustisches und/oder optisches Signal für die Bedienungsperson abgibt um anzuzeigen, daß der Gurtförderer 9 mit neuen Vorratsstapeln 6', 6'' aufzufüllen ist.In addition, a further optical scanner 26 can be arranged in the area in which there is normally a supply stack 6 'in the waiting position for conveying into the magazine shaft 1, which emits an acoustic and / or optical signal for the operator when there is no supply stack 6' indicate that the belt conveyor 9 is to be filled with new storage stacks 6 ', 6' '.

Die Zwischenräume zwischen den Führungen 7 und der Mittelwand 2 und den Führungen 4 dienen dazu, ein leichtes manuelles Füllen des leeren oder nahezu leeren Magazinschachtes 1 zu ermöglichen, ohne daß sich einzelne Kartonzuschnitte 3 verklemmen oder verkanten.The spaces between the guides 7 and the middle wall 2 and the guides 4 serve to enable easy manual filling of the empty or almost empty magazine shaft 1 without individual cardboard blanks 3 jamming or jamming.

Anstelle eines Gurtförderers 9 läßt sich auch ein Schiebeförderer verwenden, der beispielsweise eine Reihe von Schieberwänden aufweist, die jeweils an einem Vorratsstapel 6', 6'' angreifen, wenn sie zwischen diese eingeführt sind. Hierbei würde sich der optische Abtaster 25 erübrigen, da immer nur ein bestimmter Hub ausgeführt wird.Instead of a belt conveyor 9, it is also possible to use a sliding conveyor which, for example, has a series of sliding walls, each of which engages a supply stack 6 ', 6' 'when they are inserted between them. This would make the optical scanner 25 superfluous, since only a certain stroke is carried out.

Statt der an den Hebeln 20 befindlichen Auflageplatten 21 können in den Magazinschacht 1 ein- bzw. aus diesem ausklappbare Tragleisten für den jeweiligen Vorratsstapel 6' verwendet werden, deren Breite kleiner als der Abstand zwischen der Unterseite des Vorratsstapels 6' und der Oberkante 23 des Stapels 6 bei der Freigabe des Vorratsstapels 6' sein muß.Instead of the support plates 21 located on the levers 20, support strips which can be folded in or out of the magazine shaft 1 can be used for the respective storage stack 6 ', the width of which is smaller than the distance between the underside of the storage stack 6' and the upper edge 23 of the stack 6 must be 6 'when the supply stack is released.
