Description

Die Erfindung betrifft ein Faltschachtel-Magazin in einer Verpackungsmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a folding box magazine in a packaging machine according to the preamble of claim 1.

Bei Betrieb einer Verpackungsmaschine ist es notwendig, die anfangs in flach zusammengelegtem Zustand befindlichen Faltschachteln aufzurichten und stetig der eigentlichen Verpackungseinheit zuzuführen. Zu diesem Zweck werden Faltschachteln mittels eines Zuführbandes einem in der Regel schräg nach unten geneigten, als Zwischenlager dienenden Magazinschacht zugeführt, in dem sie in gestapelter Form aufgenommen werden. Der Magazinschacht ist unterseitig offen, so daß die jeweils untere Faltschachtel des Stapels mittels eines Greifers erfaßt und aus dem Magazinschacht entnommen werden kann. Der Greifer ist Teil einer umlaufenden Übergabevorrichtung, mit der die Faltschachteln unter gleichzeitiger Aufrichtung auf einer weiterführenden Transportvorrichtung, üblicherweise der sogenannten Faltschachtelkette, abgelegt werden können.When operating a packaging machine, it is necessary to those initially in a flat state Folding boxes to erect and steady the actual one Supply packaging unit. To this end folding boxes into a by means of a feed belt usually inclined downwards, as an intermediate storage serving magazine shaft in which they are stacked in Form to be included. The magazine slot is open on the underside, so that the respective lower folding box of the stack by means of a gripper and from the Magazine shaft can be removed. The gripper is Part of a rotating transfer device with which the Folding boxes with simultaneous erection on one advanced transport device, usually the so-called folding box chain, can be stored.

Die zuverlässige Funktion des Faltschachtel-Magazins und der Übergabevorrichtung ist wesentlich davon abhängig, daß die Abmessungen und Positionen der einzelnen Bauteile in Abhängigkeit von dem Format der zu handhabenden Faltschachtel genau aufeinander abgestimmt sind. Da in einer Verpackungsmaschine Faltschachteln unterschiedlichen Formats verarbeitet werden sollen, ist es notwendig, die einzelnen Bauteil bei einem Formatwechsel relativ zueinander zu verstellen. Zu diesem Zweck ist es bekannt, einerseits die Übergabevorrichtung zusammen mit dem Magazinschacht relativ zu der weiterführenden Faltschachtelkette vertikal auszurichten und andererseits den Magazinschacht relativ zu der Entnahmeposition des Greifers der Übergabevorrichtung einzustellen. Darüber hinaus kann der Magazinschacht in seiner Breite auch an die Breite der zusammengelegten Faltschachtel angepaßt werden. Die Verstellbewegungen der Übergabevorrichtung und des Magazinschachtes führen dazu, daß auch das Zuführband neu positioniert werden muß. Dies geschieht üblicherweise über mehrere Spindeltriebe, mit denen das Zuführband jeweils an seinem vorderen, dem Magazinschacht zugewandten Ende sowie seinem hinteren Ende höhenverstellbar ist und in Richtung des Magazinschachts sowie in Gegenrichtung verlagert werden kann. Diese vielfachen Einstellbewegungen an beiden Enden des Zuführbandes sind sehr mühsam und zeitaufwendig, wodurch eine Formatumstellung relativ lange dauert. Darüber hinaus ist der konstruktive Aufwand für die Verstellvorrichtungen des Zuführbandes relativ groß und somit teuer.The reliable function of the folding box magazine and the transfer device is essentially dependent on that the dimensions and positions of each component depending on the format of the folding box to be handled are precisely coordinated. There in one Packaging machine folding boxes different Format to be processed, it is necessary to individual component when changing formats relative to each other to adjust. For this purpose it is known on the one hand the transfer device together with the Magazine slot relative to the continuing folding box chain to align vertically and on the other hand the Magazine shaft relative to the removal position of the gripper adjust the transfer device. Furthermore the width of the magazine slot can also be Width of the folded folding box can be adjusted. The adjustment movements of the transfer device and of the magazine shaft also cause the feed belt must be repositioned. This usually happens via several spindle drives with which the feed belt each on its front, facing the magazine slot End and its rear end is adjustable in height and in the direction of the magazine shaft and in the opposite direction can be relocated. These multiple adjustments at both ends of the feed belt are very troublesome and time consuming, making format change relative takes long. In addition, the design effort for the adjusting devices of the feed belt relative large and therefore expensive.

US-A-3 429 570 offenbart einen Magazin schacht, der starr mit einem Zuführband verbunden ist.US-A-3 429 570 discloses a magazine chute that is rigid with a feed belt connected is.

Der Erfindung liegt die Aufgabe zugrunde, ein Faltschachtel-Magazin der genannten Art zu schaffen, bei der sich das Zuführband bei einem Formatwechsel in einfacher und schneller Weise verstellen läßt.The invention has for its object a folding box magazine of the type mentioned, in which the feed belt when changing the format in simple and can be adjusted more quickly.

Diese Aufgabe wird erfindungsgemäß bei einem gattungsgemäßen Faltschachtel-Magazin durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention in a generic folding box magazine by the characterizing features of claim 1 solved.

Erfindungsgemäß wird von der Überlegung ausgegangen, für das Zuführband keine eigenen, individuell einstellbaren Verstelleinheiten vorzusehen, sondern die Verstellung des Zuführbandes an die Verstellbewegungen der Übergabevorrichtung bzw. des Greifers sowie des Magazinschachtes, die durch die erste und zweite Verstellvorrichtung bewirkt werden, zu koppeln. Zu diesem Zweck ist das Zuführband an seinem vorderen Ende in dem ersten Lager mittelbar oder unmittelbar an dem Magazinschacht gelenkig gelagert. Wenn der Magazinschacht durch die Einstellbewegungen der ersten und zweiten Verstellvorrichtung eine vertikale und/oder horizontale Verlagerung erfährt, wird auch das erste Lager des Zuführbandes entsprechend verlagert. Dies führt dazu, daß auch das hintere Ende des Zuführbandes einer Verlagerung in horizontaler und/oder vertikaler Richtung unterliegt. Da das hintere Ende des Zuführbandes in dem zweiten Lager über die Steuerkurve zwangsgeführt ist, ist zu jeder Position des ersten Lagers eine eindeutige Position des zweiten Lagers vorbestimmt, so daß für den möglichen Verstellbereich der ersten und zweiten Verstellvorrichtung geeignete Ausrichtungen des Zuführbandes vorgegeben werden können. Auf diese Weise stellt sich das Zuführband selbsttätig in die geeignete Position, wenn die erste und/oder zweite Verstellvorrichtung aktiviert werden. Separate Antriebe oder Verstelleinheiten sind somit für das Zuführband nicht notwendig, wodurch der konstruktive Aufwand gering gehalten werden kann. Dabei ist die Steuerkurve so ausgestaltet, daß das Zuführband entweder horizontal ausgerichtet ist oder in Transportrichtung leicht nach unten geneigt verläuft.According to the invention, the consideration is assumed for the feed belt does not have its own, individually adjustable Adjustment units to provide, but the adjustment of the Feed belt to the adjustment movements of the transfer device or the gripper and the magazine shaft, caused by the first and second adjustment device are going to couple. For this purpose the feed belt is indirectly at its front end in the first camp or articulated directly on the magazine shaft stored. If the magazine shaft by the adjustment movements the first and second adjustment device experienced vertical and / or horizontal displacement the first bearing of the infeed belt has also been shifted accordingly. This means that the rear end of the Feed belt of a shift in horizontal and / or vertical direction. Since the rear end of the Feed belt in the second warehouse on the control curve is forced to any position of the first Predetermined a clear position of the second camp, so that for the possible adjustment range first and second adjustment suitable orientations of the feed belt can be specified. On in this way, the feed belt sets itself in the suitable position when the first and / or second adjustment device to be activated. Separate drives or Adjustment units are therefore not for the feed belt necessary, which keeps the design effort low can be. It is the control curve designed so that the Feed belt is either aligned horizontally or in Transport direction is inclined slightly downwards.

Die Ausrichtung des Zuführbandes in den einzelnen Positionen wird maßgeblich durch die am zweiten Lager wirksame Steuerkurve bestimmt. Vorteilhafterweise ist vorgesehen, daß das Zuführband in seinem zweiten Lager ebenfalls gelenkig gelagert ist und mittels der Steuerkurve horizontal und vertikal verlagert werden kann.The orientation of the feed belt in the individual positions becomes decisive through the effective at the second camp Control curve determined. It is advantageously provided that that the feed belt also in its second warehouse is articulated and by means of the control curve can be moved horizontally and vertically.

Eine kreisbogenförmige Steuerkurve läßt sich in einfacher Weise dadurch erreichen, wenn das zweite Lager, das als Schwenklager ausgebildet ist, das eine endseitige Lager einer Pendelstütze bildet, die an ihrem anderen Ende gelenkig und unverschieblich an der Verpackungsmaschine bzw. deren Gestell gelagert ist. Dabei liegt der gestellfeste Lagerpunkt der Pendelstütze vorzugsweise genau unter oder oberhalb des Zuführbandes, so daß die Schwenkbewegung der Pendelstütze im wesentlichen in der Längsmittelebene des Zuführbandes erfolgt.An arc-shaped control curve can be done in a simpler way Way by reaching if the second camp that as Swivel bearing is formed, the one end bearing a pendulum support that forms at its other end flexible and immovable on the packaging machine or whose frame is stored. The frame is fixed Bearing point of the pendulum support preferably exactly below or above the feed belt so that the pivoting movement the pendulum support essentially in the longitudinal median plane of the feed belt.

Die beiden Lager der Pendelstütze sollten in allen Einstellpositionen in Richtung des Magazinschachtes gegeneinander versetzt sein, so daß bei der Verstellung eine stetige Aufwärts- oder Abwärtsbewegung gewährleistet ist.The two bearings of the pendulum support should be in all setting positions towards each other in the direction of the magazine shaft be offset so that when adjusting a steady upward or downward movement is guaranteed.

Für die Verstellung der Übergabevorrichtung sowie des Magazinschachtes ist vorzugsweise vorgesehen, daß ein den. Magazinschacht tragendes Trägerteil über die zweite Verstellvorrichtung an einem die Übergabevorrichtung lagernden Grundteil verstellbar gelagert ist und daß das erste Lager des Zuführbandes an dem Trägerteil ausgebildet ist. Dabei kann mit der ersten Verstellvorrichtung eine lineare, vertikale Verstellbewegung auf das Grundteil aufgebracht werden, während mit der zweiten Verstellvorrichtung auf das Trägerteil eine lineare Verstellbewegung in einer Richtung aufbringbar ist, die parallel zur Ebene der unteren Faltschachtel des im Magazinschacht befindlichen Stapels verläuft.For the adjustment of the transfer device and the Magazine shaft is preferably provided that the. Carrier part supporting the magazine shaft over the second Adjustment device on a the transfer device underlying base is adjustable and that the first bearing of the feed belt is formed on the carrier part is. You can use the first adjustment device a linear, vertical adjustment movement on the base part be applied while using the second adjustment device a linear adjustment movement on the carrier part can be applied in a direction that parallel to the level of the lower folding box of the im Magazine stack located runs.

Ein in Figur 1 dargestelltes Faltschachtel-Magazin 10 besitzt einen in einer Verpackungsmaschine fest montierten Lagerblock 16, in dem eine vertikale Verstellspindel 15 gelagert ist, die mit einem Zwischenteil 11a derart in Eingriff steht, daß dieses entlang einer Führung 17 vertikal auf und ab verstellbar ist, wie durch den Doppelpfeil V1 angedeutet ist.A folding box magazine 10 shown in FIG. 1 has a bearing block 16 which is fixedly mounted in a packaging machine and in which a vertical adjusting spindle 15 is mounted which engages with an intermediate part 11a in such a way that it can be adjusted vertically up and down along a guide 17 , as indicated by the double arrow V 1 .

An dem Zwischenteil 11a ist ein Grundteil 11 befestigt, an dem eine Übergabevorrichtung 13, die nur schematisch angedeutet ist, gelagert ist. Die Übergabevorrichtung 13 besitzt einen Greifer 14, der in einer in oder parallel zur Zeichenebene liegenden vertikalen Ebene umläuft, wobei die Bewegungsbahn des Greifers 14 eine Hypozykloidenbahn Z mit vier Umkehrpunkten ist, die in herkömmlicher Weise mittels eines Planetengetriebes erzeugt wird.A base part 11 is fastened to the intermediate part 11a, on which a transfer device 13, which is only schematic is indicated, is stored. The transfer device 13 has a gripper 14 in one in or in parallel to the vertical plane lying around the drawing plane, where the path of movement of the gripper 14 is a hypocycloid path Z is with four reversal points, which in conventional Generated by means of a planetary gear becomes.

An dem Grundteil 11 sowie dem Zwischenteil 11a ist desweiteren eine Basis 11b fest montiert, die eine Verstellspindel 18 drehbar lagert, die mit einem an einem Tragteil 20 ausgebildeten Eingriffsteil 19 in Eingriff steht. Am oberen Ende des Tragteils 20 ist ein von beabstandeten Seitenwänden 22 und 23 gebildeter Magazinschacht 31 angeschlossen, in dem Faltschachteln in Form eines Stapels aufgenommen werden können. Die Seitenwände 22 und 23 sind über eine Querleiste 24 in ihrem Abstand veränderbar, wie der Doppelpfeil V3 andeutet.Furthermore, a base 11b is fixedly mounted on the base part 11 and the intermediate part 11a, which rotatably supports an adjusting spindle 18 which engages with an engagement part 19 formed on a support part 20. At the upper end of the support part 20, a magazine shaft 31 is formed, formed by spaced side walls 22 and 23, in which folding boxes in the form of a stack can be received. The distance between the side walls 22 and 23 can be changed via a cross bar 24, as the double arrow V 3 indicates.

Wie Figur 1 zeigt, erstreckt sich der Magazinschacht 31 unter einem Winkel von ca. 45° schräg nach unten, wobei sich die Verstellspindel 18 entsprechend schräg nach oben und parallel zu der durch die untere Faltschachtel des im Magazinschacht 31 befindlichen Stapels gebildeten Ebene erstreckt. Wie durch den Doppelpfeil V2 angedeutet ist, kann durch Aktivierung der Verstellspindel 18 eine schräg nach oben oder unten gerichtete Verstellbewegung des Tragteils 20 und somit des Magazinschachtes 31 in der Zeichenebene relativ zu dem Grundteil 11 erreicht werden.As FIG. 1 shows, the magazine shaft 31 extends obliquely downwards at an angle of approximately 45 °, the adjusting spindle 18 extending accordingly obliquely upwards and parallel to the plane formed by the lower folding box of the stack located in the magazine shaft 31. As indicated by the double arrow V 2 , by activating the adjustment spindle 18, an adjustment movement of the support part 20 and thus of the magazine shaft 31 in the plane of the drawing relative to the base part 11 can be achieved.

In dem oberen linken Umkehrpunkt der Hypozykloidenbahn Z kommt der Greifer 14 mit der unteren Faltschachtel des im Magazinschacht 31 befindlichen Stapels in Anlage, ergreift diese und entnimmt sie dem Magazinschacht 31. Bei der Bewegung entlang der Hypozykloidenbahn Z wird die Faltschachtel in nicht dargestellter Weise aufgerichtet und im gegenüberliegenden, gemäß Figur 1 rechten unteren Umkehrpunkt an eine weiterführende Transportvorrichtung, insbesondere die Faltschachtelkette 32, abgegeben. Durch Aktivierung der Verstellspindel 15 kann das Zwischenteil 11a zusammen mit dem Grundteil 11 und der daran gelagerten Übergabevorrichtung 13 sowie dem Basisteil 11b, dem Tragteil 20 und dem Magazinschacht 31 vertikal relativ zu der Faltschachtelkette 32 verstellt werden.In the upper left reversal point of the hypocycloid path Z comes the gripper 14 with the lower carton in Magazine stack 31 located in the plant, takes hold this and removes it from the magazine shaft 31 the movement along the hypocycloid path Z becomes the Folding box erected in a manner not shown and in the opposite, lower right according to Figure 1 Turning point to a further transport device, in particular the folding box chain 32, delivered. By Activation of the adjusting spindle 15 can be the intermediate part 11a together with the base part 11 and the one mounted thereon Transfer device 13 and the base part 11b, the Support member 20 and the magazine shaft 31 vertically relative to the folding box chain 32 can be adjusted.

Im oberen Bereich des Tragteils 20 ist nahe dem Magazinschacht 31 ein Traggestell 25 eines Zuführbandes 26 über ein erstes Lager 21 gelenkig angeschlossen. Das Zuführband 26 ist als endlos umlaufender Zahnriemen ausgebildet, der über zwei endseitige Zahnriemenscheiben 27a und 27b verläuft und im wesentlichen in der Zeichenebene umläuft. Nahe dem hinteren, dem Magazinschacht 31 abgewandten Ende ist das Lagerteil 25 über ein zweites Schwenklager 28 an das obere Ende einer Pendelstütze 29 angeschlossen, die an ihrem unteren Ende in einem Schwenklager 30 gestellfest in der Verpackungsmaschine gehalten ist. Das untere Lager 30 liegt unterhalb des Zuführbandes 26 und ist gegenüber dem oberen zweiten Lager 28 in Richtung des Magazinschachtes 31 versetzt, so daß für das zweite obere Lager 28 durch die Pendelstütze 29 eine Zwangsführung auf einem um das untere Lager 30 verlaufenden Kreisbogen in der Zeichenebene gegeben ist.In the upper area of the support part 20 is near the magazine shaft 31 a support frame 25 of a feed belt 26 via a first bearing 21 connected in an articulated manner. The feed belt 26 is designed as an endlessly rotating toothed belt, the over two end toothed pulleys 27a and 27b runs and essentially in the plane of the drawing circulates. Near the rear, facing away from the magazine shaft 31 End is the bearing part 25 via a second Swivel bearing 28 at the upper end of a pendulum support 29 connected at its lower end in one Swivel bearing 30 fixed to the frame in the packaging machine is held. The lower bearing 30 is below the Feed belt 26 and is opposite the upper second Bearing 28 offset in the direction of the magazine shaft 31, see above that for the second upper bearing 28 by the pendulum support 29 a positive guidance on a around the lower bearing 30 running circular arc is given in the drawing plane.

Mittels des Zuführbandes 26 können auf dessen Obertrum liegende Faltschachteln in den Magazinschacht eingeführt und dort gestapelt werden.By means of the feed belt 26 can on the upper strand horizontal folding boxes inserted into the magazine shaft and stacked there.

Wenn das Faltschachtel-Magazin auf ein anderes Faltschachtelformat umgestellt werden soll, wird zunächst über die die erste Verstellvorrichtung bildende vertikale Verstellspindel 15 die vertikale Position der Übergabevorrichtung 13 sowie des Magazinschachtes 31 relativ zur Faltschachtelkette 32 verändert. Eine veränderte Einstellung ist in Figur 2 dargestellt, wobei in dem gezeigten Ausführungsbeispiel die Übergabevorrichtung 13 und der Magazinschacht 31 abgesenkt wurden. Gleichzeitig kann durch Aktivierung der Verstellspindel 18 eine Verstellung der Relativposition zwischen dem Greifer 14 in seiner Übernahmeposition und der unteren Faltschachtel des im Magazinschachtes 31 befindlichen Stapels verändert werden. Desweiteren wird der Abstand der Seitenwände 22 und 23 des Magazinschachtes 31 auf das neue Faltschachtelformat eingestellt. Infolge der Verstellungen der Verstellspindeln 15 und 18 erfährt das erste Lager 21 des Zuführbandes 26 eine Verlagerung, die zu einer Verlagerung des hinteren zweiten Lagers 28 entlang der von der Pendelstütze 29 vorgegebenen Kreisbahn führt. Die sich dabei einstellende Position des Zuführbandes 26 ist in Figur 2 dargestellt. Aufgrund der vorderen, am Tragteil 20 ausgebildeten Schwenklagerung des Zuführbandes 26 und seiner hinteren pendelnden Lagerung ist es möglich, daß das Zuführband 26 den durch die Verstellspindeln 15 und 18 vorgegebenen Verstellbewegungen selbstätig folgt, ohne daß weitere Einstellungen vorgenommen werden müssen.If the folding box magazine is on a different folding box format will be changed first over the vertical forming the first adjustment device Adjustment spindle 15 the vertical position of the transfer device 13 and the magazine shaft 31 relative to Folding box chain 32 changed. A changed attitude is shown in Figure 2, wherein in the shown Embodiment the transfer device 13 and Magazine shaft 31 were lowered. At the same time by activating the adjusting spindle 18 an adjustment the relative position between the gripper 14 in its Takeover position and the lower folding box of the im Magazine shaft 31 stack can be changed. Furthermore, the distance between the side walls 22 and 23 of the magazine slot 31 to the new folding box format set.
