Definitions
- the invention is based on a magazine for stacking and individually dispensing flat objects, in particular flat-lying folding boxes according to the preamble of claim 1.
- the delivery shaft adjoins the horizontal conveyor at an angle of approximately 45 °, so that the folding boxes which are conveyed into the delivery shaft and lie transversely therein Are inclined to the vertical. They are supported with the one trailing edge on the wall of the discharge shaft near the conveyor, so that the slipping in the discharge shaft is subject to frictional forces.
- the leading edge of the obliquely conveyed folding boxes comes to rest with the higher area near the other edge of the folding boxes stacked in the delivery chute, so that the folding boxes pushed forward by the conveying device load the folding boxes stacked in the chute on one side, since between the a gap in the form of a wedge is formed in the delivery chute entering and the folding boxes already stacked there, the tip of which lies in the region of the leading edge of the folding boxes.
- frictional forces act on the folding boxes in the discharge shaft and pressure is exerted on the one hand, which is transferred to the lowest folding box in the discharge shaft, the removal or removal of the lowest folding box from the discharge shaft is made more difficult, namely unevenly depending on the respective delivery pressure and of the respective friction conditions.
- a magazine is known from EP-A-100 143, in which parallel guide rails adjoin the horizontal conveying device and delimit an inclined discharge chute in which the inserted folding boxes are arranged at a relatively steep angle.
- the folding boxes stand with their lower edges on the lower rails and are supported with their upper edges on the upper rails.
- the folding boxes which are fed on the conveyor at a relatively flat incline, are erected steeply by the inclination of the guide rails.
- the disadvantage here is that the upper edge areas of the folding boxes are pressed strongly against each other when they are placed in the steep position, so that the foremost folding box in the delivery shaft is under a relatively high pressing pressure.
- this pressure is not constant, but depends on the respective stock of folding boxes on the conveyor.
- a feed device for cardboard blanks in which a vertical discharge shaft connects to a horizontal conveyor belt.
- the flat blanks set up on the conveyor belt lean against a driven stop roller in a very steep inclined position with their upper edge areas with a slight overhang over the discharge chute.
- the conveying device is being driven, the foremost blank slides with its lower edge on the front deflection section of the conveyor belt into the delivery shaft, the rotation of the stop roller supporting the downward movement of the blank.
- the cut-to-size cut in this way which is in a steep inclined position, then tilts into the delivery chute.
- a touch device on the delivery chute controls the drive of the conveyor device in order to achieve a minimum height of the stack of blanks in the delivery chute.
- the magazine according to the invention with the characterizing features of claim 1 has the advantage that constant removal conditions are created for the constant removal of folding boxes by the constant stack height in the delivery shaft and that the magazine can be refilled with folding boxes by the operator at an easily accessible working height. Furthermore, the relatively slight tilting of the foremost folding box from the conveyor into the discharge shaft results in a high level of operational safety.
- FIG. 1 shows a first exemplary embodiment of a folding box magazine in a simplified side view
- FIG. 2 shows the transition of a conveying device into a delivery shaft of the magazine according to FIG. 1 in a diagrammatic representation.
- the magazine for holding a supply of folding boxes 1 and for dispensing one folding box each has a conveyor device 10 and a delivery slot 11.
- the conveyor device 10 has, for example, two parallel, endless conveyor belts 12, 13, the upper of which Lie dummies 15 on a table 16.
- the table 16 and the upper run 15 extend essentially in a horizontal plane, preferably they rise slightly towards the end of the conveyor belts 12, 13.
- the conveyor belts 12, 13 are guided around deflection rollers 17, which are driven by a motor 18 via a chain drive 19.
- the conveyor belts 12, 13 designed as toothed belts have sawtooth-shaped teeth 14 on their outside, the tips of which point in the conveying direction.
- the discharge shaft 11 adjoins at a great incline, preferably in a vertical orientation. It is essentially formed from opposite vertical guide walls or rails 21, 22, which have projecting retaining lugs 23 at their lower ends lying in a common plane.
- a height-adjustable button 24 is arranged on the side of the discharge shaft 11, which detects the absence or sinking of folding boxes 1 in the discharge shaft 11 and controls the electric motor 18 for the conveying device 10 for filling up the shaft with folding boxes.
- the lower, open end of the delivery chute 11 is assigned a movable suction head 25, which in each case pulls the bottom folding box 1 resting on the holding lugs 23 downward from the delivery chute 11 and transfers it to a conveyor device, not shown, of a packaging machine.
- the folding boxes 1 to be processed are placed in stacks on the table 16 or the upper runs 15 of the conveyor belts 12, 13 running thereon by an operator, in an inclined position in which the folding boxes 1 with their upper edges in the conveying direction of the conveyor belts 12, 13 are inclined in an angular range of 30 ° to 60 °.
- the folding boxes 1 In the area of the transition from the conveying device 10 into the discharge shaft 11, the folding boxes 1 successively tilt downwards from their inclined position into a horizontal position onto the upper end of the stack of folding boxes formed in the discharge shaft 11.
- the height of the folding box stack in the delivery shaft 11 is monitored by the button 24, which switches on the motor 18 of the conveyor 10 when the stack sinks, so that the conveyor belts 12, 13 push the folding box stack in the direction of the receiving shaft 11.
- a plurality of rollers 30 are arranged at the conveying end of the conveying device 10, coaxially with the axis of the deflecting rollers 17 for the conveyor belts 12, 13, which are firmly connected to the deflecting rollers 17 and whose radius is greater than that of the deflecting rollers 17 , preferably equal to the sum of the radius of the deflection rollers 17 and the greatest thickness of the conveyor belts 12, 13, so that the folding boxes 1 lying in the deflection region of the conveyor belts 12, 13 lying on the circumference of the rollers 30 out of engagement with the teeth 14 of the conveyor belts 12, 13 reach.

Description
Die Erfindung geht aus von einem Magazin zum gestapelten Aufnehmen und einzelnen Abgeben von flachen Gegenständen, insbesondere von flachliegenden Faltschachteln nach der Gattung des Anspruchs 1.The invention is based on a magazine for stacking and individually dispensing flat objects, in particular flat-lying folding boxes according to the preamble of claim 1.
Bei einem beispielsweise aus der FR-A 25 64 065 (Figur 4) bekannten Magazin dieser Art schließt sich der Abgabeschacht an die horizontale Fördereinrichtung in einem Winkel von etwa 45° geneigt an, so daß die in den Abgabeschacht geförderten und darin quer liegenden Faltschachteln in Schräglage zur Senkrechten angeordnet sind. Dabei stützen sie sich mit der einen, nacheilenden Kante auf der der Fördereinrichtung nahen Wand des Abgabeschachtes ab, so daß das Nachrutschen im Abgabeschacht Reibungskräften unterliegt. Ferner kommt beim Einlaufen in den Abgabeschacht zunächst die vorauseilende Kante der schrägliegend geförderten Faltschachteln mit dem höherliegenden Bereich nahe der anderen Kante der im Abgabeschacht aufgestapelten Faltschachteln zur Anlage, so daß die von der Fördereinrichtung vorgeschobenen Faltschachteln die im Schacht gestapelten Faltschachteln einseitig belasten, da zwischen den in den Abgabeschacht einlaufenden und den dort bereits gestapelten Faltschachteln eine Lücke in Form eines Keils gebildet ist, dessen Spitze im Bereich der vorauseilenden Kante der Faltschachteln liegt. Dadurch daß auf die Faltschachteln im Abgabeschacht einerseits Reibungskräfte einwirken und andererseits Druck ausgeübt wird, was auf die unterste Faltschachtel im Abgabeschacht übertragen wird, wird die Entnahme bzw. das Abziehen der untersten Faltschachtel aus dem Abgabeschacht erschwert, und zwar ungleichmäßig in Abhängigkeit vom jeweiligen Förderdruck und von den jeweiligen Reibungsverhältnissen.In a magazine of this type, known for example from FR-A 25 64 065 (FIG. 4), the delivery shaft adjoins the horizontal conveyor at an angle of approximately 45 °, so that the folding boxes which are conveyed into the delivery shaft and lie transversely therein Are inclined to the vertical. They are supported with the one trailing edge on the wall of the discharge shaft near the conveyor, so that the slipping in the discharge shaft is subject to frictional forces. Furthermore, when entering the delivery chute, the leading edge of the obliquely conveyed folding boxes comes to rest with the higher area near the other edge of the folding boxes stacked in the delivery chute, so that the folding boxes pushed forward by the conveying device load the folding boxes stacked in the chute on one side, since between the a gap in the form of a wedge is formed in the delivery chute entering and the folding boxes already stacked there, the tip of which lies in the region of the leading edge of the folding boxes. Because frictional forces act on the folding boxes in the discharge shaft and pressure is exerted on the one hand, which is transferred to the lowest folding box in the discharge shaft, the removal or removal of the lowest folding box from the discharge shaft is made more difficult, namely unevenly depending on the respective delivery pressure and of the respective friction conditions.
Ferner ist aus der EP-A-100 143 ein Magazin bekannt, bei dem sich an die horizontale Fördereinrichtung parallele Führungsschienen anschließen, die einen geneigten Abgabeschacht begrenzen, in dem die eingebrachten Faltschachteln in einem relativ steilen Winkel angeordnet sind. In dem Abgabeschacht stehen die Faltschachteln mit ihren unteren Kanten auf den unteren Schienen auf und stützen sich mit ihren oberen Kanten an den oberen Schienen ab. Beim Einlaufen in den Abgabeschacht werden die Faltschachteln, die auf der Fördereinrichtung relativ flach geneigt zugeführt werden, durch die Neigung der Führungsschienen steil aufgerichtet. Nachteilig dabei ist, daß die oberen Kantenbereiche der Faltschachteln beim Anstellen in die Steillage stark aufeinandergepreßt werden, so daß die vorderste Faltschachtel im Abgabeschacht unter einem relativ hohen Preßdruck steht. Dieser Preßdruck ist jedoch nicht konstant, sondern hängt vom jeweiligen Vorrat an Faltschachteln auf der Fördereinrichtung ab.Furthermore, a magazine is known from EP-A-100 143, in which parallel guide rails adjoin the horizontal conveying device and delimit an inclined discharge chute in which the inserted folding boxes are arranged at a relatively steep angle. In the delivery chute, the folding boxes stand with their lower edges on the lower rails and are supported with their upper edges on the upper rails. When entering the delivery chute, the folding boxes, which are fed on the conveyor at a relatively flat incline, are erected steeply by the inclination of the guide rails. The disadvantage here is that the upper edge areas of the folding boxes are pressed strongly against each other when they are placed in the steep position, so that the foremost folding box in the delivery shaft is under a relatively high pressing pressure. However, this pressure is not constant, but depends on the respective stock of folding boxes on the conveyor.
Außerdem ist aus der DE-A 23 21 771 eine Zuführvorrichtung für Kartonzuschnitte bekannt, bei der sich an ein waagrechtes Förderband ein senkrechter Abgabeschacht anschließt. Die flachen, auf dem Förderband aufgestellten Zuschnitte lehnen sich in sehr steiler Schräglage mit ihren oberen Kantenbereichen mit leichtem Überhang über den Abgabeschacht an einer angetriebenen Anschlagrolle an. Beim Vortrieb der Fördereinrichtung rutscht jeweils der vorderste Zuschnitt mit seiner unteren Kante an der vorderen Umlenkstrecke des Förderbandes in den Abgabeschacht ab, wobei die Drehung der Anschlagrolle die Abwärtsbewegung des Zuschnitts unterstützt. Der so freigestellte, in steiler Schräglage sich befindende Zuschnitt kippt darauf in den Abgabeschacht. Auch hier steuert eine Tasteinrichtung am Abgabeschacht den Antrieb der Fördereinrichtung, um eine Mindesthöhe des Zuschnittstapels im Abgabeschacht zu erzielen. Obwohl bei dieser bekannten Vorrichtung ein Entnehmen des untersten Zuschnitts im Abgabeschacht wegen kleiner, gleichbleibender Drücke gewährleistet ist, ist das Überführen der Zuschnitte vom Förderband in den Abgabeschacht wegen der steilen Schräglage der Zuschnitte sehr problematisch.In addition, from DE-A 23 21 771 a feed device for cardboard blanks is known, in which a vertical discharge shaft connects to a horizontal conveyor belt. The flat blanks set up on the conveyor belt lean against a driven stop roller in a very steep inclined position with their upper edge areas with a slight overhang over the discharge chute. When the conveying device is being driven, the foremost blank slides with its lower edge on the front deflection section of the conveyor belt into the delivery shaft, the rotation of the stop roller supporting the downward movement of the blank. The cut-to-size cut in this way, which is in a steep inclined position, then tilts into the delivery chute. Here, too, a touch device on the delivery chute controls the drive of the conveyor device in order to achieve a minimum height of the stack of blanks in the delivery chute. Although in this known device the removal of the lowest blank in the delivery chute is ensured because of the small, constant pressures, the transfer of the cuttings from the conveyor belt into the delivery chute is very problematic because of the steep inclined position of the blanks.
Das erfindungsgemäße Magazin mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, daß durch die konstante Stapelhöhe im Abgabeschacht gleichbleibende Entnahmebedingungen für die ständige Entnahme von Faltschachteln geschaffen werden und daß das Magazin von der Bedienungsperson in einer leicht erreichbaren Arbeitshöhe mit Faltschachteln nachgefüllt werden kann. Ferner ergibt sich durch das verhältnismäßig geringfügige Abkippen der vordersten Faltschachtel von der Fördereinrichtung in den Abgabeschacht eine hohe Betriebssicherheit.The magazine according to the invention with the characterizing features of claim 1 has the advantage that constant removal conditions are created for the constant removal of folding boxes by the constant stack height in the delivery shaft and that the magazine can be refilled with folding boxes by the operator at an easily accessible working height. Furthermore, the relatively slight tilting of the foremost folding box from the conveyor into the discharge shaft results in a high level of operational safety.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Anspruchs 1 angegebenen Magazins möglich. Dadurch wird ein besonders einfaches und reibungsloses Übergeben von Faltschachteln aus dem Bereich der Fördereinrichtung in den Abgabeschacht ermöglicht.Advantageous further developments and improvements of the magazine specified in claim 1 are possible through the measures listed in the subclaims. This enables a particularly simple and smooth transfer of folding boxes from the area of the conveyor into the discharge shaft.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden in der nachfolgenden Beschreibung näher erläutert. Es Zeigen Figur 1 ein erstes Ausführungsbeispiel eines Faltschachtel-Magazins vereinfacht in Seitenansicht und Figur 2 den Übergang einer Fördereinrichtung in einen Abgabeschacht des Magazins nach Figur 1 in schaubildlicher Darstellung.Exemplary embodiments of the invention are shown in the drawing and are explained in more detail in the following description. 1 shows a first exemplary embodiment of a folding box magazine in a simplified side view, and FIG. 2 shows the transition of a conveying device into a delivery shaft of the magazine according to FIG. 1 in a diagrammatic representation.
Das Magazin zum Aufnehmen eines Vorrats an Faltschachteln 1 und zum Abgeben jeweils einer Faltschachtel hat eine Fördereinrichtung 10 und einen Abgabeschacht 11. Die Fördereinrichtung 10 weist beispielsweise zwei parallel verlaufende, endlose Förderbänder 12, 13 auf, deren obere Trumme 15 auf einem Tisch 16 aufliegen. Der Tisch 16 und die oberen Trumme 15 erstrecken sich im wesentlichen in waagrechter Ebene, vorzugsweise steigen sie zum Förderende der Förderbänder 12, 13 leicht an. Am Förderende sind die Förderbänder 12, 13 um Umlenkrollen 17 geführt, die von einem Motor 18 über einen Kettentrieb 19 angetrieben werden. Die als Zahnriemen ausgebildeten Förderbänder 12, 13 haben auf ihrer Außenseite sägezahnförmige Zähne 14, deren Spitzen in Förderrichtung zeigen.The magazine for holding a supply of folding boxes 1 and for dispensing one folding box each has a
An das Förderende der Förderbänder 12, 13 schließt sich der Abgabeschacht 11 nach unten mit großer Neigung, vorzugsweise in senkrechter Ausrichtung an. Er wird im wesentlichen aus gegenüberliegenden senkrechten Führungswänden oder -schienen 21, 22 gebildet, welche an ihren unteren, in einer gemeinsamen Ebene liegenden Enden vorstehende Haltenasen 23 haben. Am Abgabeschacht 11 ist seitlich ein Taster 24 höhenverstellbar angeordnet, der das Fehlen bzw. Absinken von Faltschachteln 1 im Abgabeschacht 11 feststellt und den Elektromotor 18 für die Fördereinrichtung 10 zum Auffüllen des Schachtes mit Faltschachteln ansteuert. Dem unteren, offenen Ende des Abgabeschachtes 11 ist ein bewegbarer Saugkopf 25 zugeordnet, der jeweils die unterste, auf den Haltenasen 23 aufliegende Faltschachtel 1 nach unten aus dem Abgabeschacht 11 herauszieht und an eine nicht dargestellte Fördereinrichtung einer Verpackungsmaschine übergibt.At the conveying end of the
Die zu verarbeitenden Faltschachteln 1 werden in Stapeln auf den Tisch 16 bzw. die darauf verlaufenden oberen Trumme 15 der Förderbänder 12, 13 von einer Bedienungsperson aufgelegt und zwar in einer Schräglage, in der die Faltschachteln 1 mit ihren oberen Kanten in Förderrichtung der Förderbänder 12, 13 geneigt sind und zwar in einem Winkelbereich von 30° bis 60°. Dadurch ergibt sich am Übergang der Fördereinrichtung 10 in den Abgabeschacht 11 ein Abbrechen des Faltschachtel-Stapels, so daß zwischen dem auf den Förderbändern 12, 13 liegenden Stapel von Faltschachteln 1 und dem in dem Abgabeschacht 11 befindlichen Stapel von Faltschachteln 1 eine keilförmige Lücke gebildet wird, wobei die vordersten Faltschachteln 1 des auf der Förderbändern 12, 13 und dem Tisch 16 ruhenden Stapels am Übergang von der Fördereinrichtung 10 in den Abgabeschacht 11 deren oberen, vorauseilenden Kanten in den Abgabeschacht 11 vorstehen. Im Bereich des Übergangs von der Fördereinrichtung 10 in den Abgabeschacht 11 kippen die Faltschachteln 1 nacheinander aus ihrer Schräglage nach unten in eine waagrechte Lage auf das obere Ende des im Abgabeschachts 11 gebildeten Stapels von Faltschachteln. Die Höhe des Faltschachtel-Stapels im Abgabeschacht 11 wird vom Taster 24 überwacht, der den Motor 18 der Fördereinrichtung 10 einschaltet, wenn der Stapel absinkt, so daß die Förderbänder 12, 13 den Faltschachtel-Stapel in Richtung Aufnahmeschacht 11 nachschieben.The folding boxes 1 to be processed are placed in stacks on the table 16 or the
Bei dem Ausführungsbeispiel nach den Figuren 1 und 2 sind am Förderende der Fördereinrichtung 10 gleichachsig zur Achse der Umlenkrollen 17 für die Förderbänder 12, 13 mehrere Rollen 30 angeordnet, die mit den Umlenkrollen 17 fest verbunden sind und deren Radius größer ist als der der Umlenkrollen 17, vorzugsweise gleich der Summe des Radius der Umlenkrollen 17 und der größten Dicke der Förderbänder 12, 13, so daß die Faltschachteln 1 im Umlenkbereich der Förderbänder 12, 13 auf dem Umfang der Rollen 30 aufliegend außer Eingriff mit den Zähnen 14 der Förderbänder 12, 13 gelangen. Dadurch wird der von den Förderbändern 12, 13 durch Formschluß ausgeübte Vorschub aufgehoben, so daß die vordersten Faltschachteln 1 des waagrechten Stapels, die nun in den Abgabeschacht 11 abkippen, lediglich von den nachfolgenden Faltschachteln 1 vollends von den Rollen 30 in den Abgabeschacht 11 geschoben werden. Dabei unterstützen ihre nacheilenden Kantenbereiche die nachfolgenden Faltschachteln 1, die vom Gewicht und vom Druck der daran sich anschließenden Faltschachteln 1 in Schräglage gehalten werden, so daß die vordersten Faltschachteln 1 des waagrechten Stapels die oben beschriebene Lücke bilden. Bei diesem Unterstützen der nachfolgenden Faltschachteln 1 im waagrechten Stapel wird der ausgeübte Druck oder das Gewicht nicht auf die Faltschachteln 1 im Abgabeschacht 11 übertragen, sondern von den Rollen 30 aufgenommen, so daß lediglich das Gewicht der im Abgabeschacht 11 liegenden Faltschachteln 1 für den Druck an den Haltenasen 13 maßgebend ist.In the exemplary embodiment according to FIGS. 1 and 2, a plurality of
