Description

Die Erfindung betrifft eine Vorrichtung zum Entnehmen von Gegenständen von einem Stapel derartiger Gegenstände mit einer den Stapel tragenden Stapelauflage und einem mit wenigstens einem Mitnehmer versehenen Entnahmeförderer, dessen Mitnehmer zum Entnehmen von Gegenständen vom Stapel in das Stapelprofil eingreift.The invention relates to a device for removing objects from a stack of such objects with a stack support supporting the stack and a removal conveyor provided with at least one driver, the driver of which engages in the stack profile for removing objects from the stack.

Regelmäßig geformte Gegenstände wie Schreibhefte, Blöcke aus Papier oder anderem Blattmaterial, eingeschlagene Papierstapel, Schachteln, Pakete und dergl., werden zum Weiterverarbeiten oder Verpacken gewöhnlich in einem Stapel derartiger Gegenstände bereitgehalten, der auf einer Stapelauflage ruht. Mit einem Schieber werden die jeweils zu verarbeitenden Gegenstände einzeln oder in Gruppen von mehreren aufeinanderliegenden Gegenständen dem Stapel entnommen, indem sie über die Stapelauflage seitwärts unter dem Stapel herausgeschoben werden. Die entnommenen Gegenstände werden zur Weiterverarbeitung beispielsweise einer Verpackungsmaschine zugeführt.Regularly shaped objects such as exercise books, blocks of paper or other sheet material, wrapped stacks of paper, boxes, packages and the like are usually kept ready for further processing or packaging in a stack of such objects which rests on a stacking support. The objects to be processed are removed from the stack individually or in groups of several objects lying on top of one another by means of a slide, in that they are pushed out sideways under the stack via the stack support. The removed items are fed to a packaging machine for further processing.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art anzugeben, mit der dieser Vorgang zuverlässig und mit geringem Aufwand realisierbar ist.The invention has for its object to provide a device of the type described above, with which this process can be implemented reliably and with little effort.

Gelöst wird dieser Aufgabe bei einer Vorrichtung der eingangs beschriebenen Art dadurch, daß die Greifhöhe des Mitnehmers relative zur Stapelauflage einstellbar ist. Die Greifhöhe der Mitnehmer kann also bei der erfindungs­gemäß vorgeschlagenen Vorrichtung auf die Höhe der dem Stapel zu entnehmenden Gegenstände eingestellt werden, was insbesondere dann von Bedeutung ist, wenn Gruppen mehrerer aufeinanderliegender Gegenstände dem Stapel ent­nommen werden sollen oder wenn leicht deformierbare Gegenstände zu behandeln sind. Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Entnahmeförderer als ein mit wenigstens einem Mitnehmer versehener, parallel zur Stapelauflage umlaufender Endlosförderer ausgebildet. In Fortführung der Erfindung ist die Stapel­auflage stationär angeordnet, und es sind Stellmittel vor­gesehen, mit denen der Entnahmeförderer relativ zur Stapel­auflage zum Zwecke der Einstellung der Greifhöhe der Mitnehmer verstellbar ist. Der besondere Vorteil dieser Anordnung ist, daß die Einstellung der Greifhöhe der Mit­nehmer mit geringem Zeit- und Personalaufwand durchführbar ist, weil alle Mitnehmer gemeinsam eingestellt werden.This object is achieved in a device of the type described in the introduction in that the gripping height of the driver is adjustable relative to the stack support. The gripping height of the drivers can thus be adjusted to the height of the objects to be removed from the stack in the device proposed according to the invention, This is particularly important when groups of several objects lying on top of one another are to be removed from the stack or when easily deformable objects are to be treated. According to a preferred embodiment of the invention, the removal conveyor is designed as an endless conveyor provided with at least one driver and rotating parallel to the stack support. In continuation of the invention, the stacking support is arranged in a stationary manner and adjusting means are provided with which the removal conveyor can be adjusted relative to the stacking support for the purpose of adjusting the gripping height of the drivers. The particular advantage of this arrangement is that the adjustment of the gripping height of the drivers can be carried out with little expenditure of time and personnel, because all drivers are set together.

Ein konstruktiv besonders günstige Ausgestaltung der Vor­richtung nach der Erfindung ergibt sich dadurch, daß der Entnahmeförderer unterhalb der Stapelauflage angeordnet ist und daß die Mitnehmer des Entnahmeförderers durch Schlitze in der Stapelauflage hindurch in das Stapelprofil eingreifen. Der Entnahmeförderer ist dabei an einem zur Stapelauflage verstellbar angeordneten Tragrahmen gelagert, was die Einstellung der Greifhöhe der Mitnehmer besonders einfach gestaltet. Als Stellmittel für die Verstellung der Lage des Entnahmeförderers zur Stapelauflage können ein motorischer Antrieb oder auch ein Handantrieb vorge­sehen sein.A structurally particularly advantageous embodiment of the device according to the invention results from the fact that the removal conveyor is arranged below the stack support and that the drivers of the removal conveyor engage through slots in the stack support in the stack profile. The removal conveyor is mounted on a support frame that is adjustable with respect to the stack support, which makes the adjustment of the gripping height of the drivers particularly simple. A motorized drive or also a manual drive can be provided as adjusting means for adjusting the position of the removal conveyor relative to the stack support.

Um die dem Stapel entnommenen Gegenstände in einem Förder­vorgang unmittelbar einer Verarbeitungsmaschine zuführen zu können, sieht eine weitere Ausgestaltung der Erfindung vor, daß die Stapelauflage in Entnahmerichtung der Gegen­stände mit einer die Stapelauflage mit einer Verarbeitungs­ maschine verbindenden Führungsbahn verbunden ist und daß der Entnahmeförderer als Fördermittel auch der Führungs­bahn zugeordnet ist. Als Verarbeitungsmaschine kann bei­spielsweise eine Folieneinschlagmaschine vorgesehen sein, in welcher die Gegenstände einzeln oder in Gruppen auf­einanderliegend in eine Kunststoffolie eingehüllt werden.In order to be able to feed the objects removed from the stack directly to a processing machine in a conveying process, a further embodiment of the invention provides that the stack support in the removal direction of the objects with one processing support machine connecting guideway is connected and that the removal conveyor is also assigned to the guideway as funding. A film wrapping machine can be provided as the processing machine, for example, in which the objects are wrapped individually or in groups lying one on top of the other in a plastic film.

Gemäß einer besonders vorteilhaften Fortführung der Erfin­dung ist oberhalb der Stapelauflage in der Entnahmerich­tung der Gegenstände ein höhenverstellbarer Rückhalte­anschlag vorgesehen, der es ermöglicht, die Entnahme von Gegenständen vom Stapel zu dosieren. Durch Einstellung der Höhedes Rückhalteanschlags und der Mitnehmer des Entnahmeförderers kann die Höhe von dem Stapel zu ent­nehmenden Teilstapeln bzw. Gegenstandsgruppen auf ein­fache Weise vorgegeben werden.According to a particularly advantageous embodiment of the invention, a height-adjustable retention stop is provided above the stacking support in the removal direction of the objects, which makes it possible to dose the removal of objects from the stack. By adjusting the height of the restraint stop and the drivers of the removal conveyor, the height of the partial stacks or groups of objects to be removed from the stack can be predefined in a simple manner.

Die Vorrichtung nach der Erfindung bietet eine sehr ein­fache Möglichkeit, die Mitnehmer des Entnahmeförderers auf verschiedene Produkte bzw. Gegenstandshöhen einzu­stellen. Dabei erfolgt die Einstellung aller Mitnehmer gemeinsam mit einem einzigen Verstellmittel, so daß die Umrüstung der Vorrichtung für die Behandlung unterschied­licher Produkte mit geringem Zeit- und Personalaufwand möglich ist. Die Verstellbarkeit der Höhe der Mitnehmer sowie die Einstellmöglichkeit des Rückhalteanschlags gestatten eine Dosierung der Entnahme von Gegenständen vom Stapel. Auf diese Weise läßt sich bei zu entnehmenden Teilstapeln bzw. von Gruppen aufeinanderliegender Gegen­stände jeweils die Anzahl der zu entnehmenden Gegenstände vorgeben. Die Einstellbarkeit der Mitnehmerhöhe ist auch dann von Vorteil, wenn die folgende Verarbeitungsmaschine eine in der Höhe beschränkte Einlaßöffnung aufweist. Hinzu kommt, daß die Vorrichtung nach der Erfindung konstruktiv sehr einfach gestaltet ist und im Betrieb leicht zu handhaben ist.The device according to the invention offers a very simple possibility of adjusting the drivers of the removal conveyor to different products or item heights. All drivers are adjusted together with a single adjusting means, so that the device can be converted for the treatment of different products with little expenditure of time and personnel. The adjustability of the height of the carriers as well as the adjustment option of the restraint stop allow dosing of the removal of objects from the stack. In this way, the number of objects to be removed can be specified in the case of partial stacks to be removed or of groups of objects lying one on top of the other. The adjustability of the driver height is also advantageous if the following processing machine has an inlet opening that is limited in height. In addition, the device according to the invention is structurally very simple and easy to operate.

Auf einer Stapelauflage 1 ruht ein Stapel 2 aus Gegen­ständen 3, die nacheinander als Teilstapel 4 dem Stapel 2 entnommen und in Richtung eines Pfeiles 6 einer Weiterverarbeitungs­maschine 7 zugeführt werden sollen. Der Stapel 2 liegt in einer Stapelaufnahme, deren vordere und hintere Begren­zungen durch Wände 8 und 8a gebildet sind. Der untere Abschnitt 8b der vorderen Begrenzungswand 8 dient dabei als Rückhalteanschlag für die beim Ausschieben eines Gegenstandes im Stapel zurückbleibenden Gegenstände. Die Begrenzungswand 8 ist höhenverstellbar, wozu sie in der Darstellung der Fig. 1 mit einem Spindeltrieb 9 und einem Antrieb 11 verbunden ist.A stack 2 of objects 3 rests on a stack support 1 and is to be removed from the stack 2 as a partial stack 4 and fed to a further processing machine 7 in the direction of an arrow 6. The stack 2 lies in a stack holder, the front and rear boundaries of which are formed by walls 8 and 8a. The lower section 8b of the front boundary wall 8 serves as a retention stop for the objects remaining in the stack when an object is pushed out. The boundary wall 8 is adjustable in height, for which purpose it is connected to a spindle drive 9 and a drive 11 in the illustration in FIG. 1.

Als Weiterverarbeitungsmaschine ist im dargestellten Aus­führungsbeispiel eine Folieneinschlagmaschine vorgesehen, deren Produkteinlauf mit Führungsrollen 12 und 12a zum Zu­führen einer Unterfolie 13 und einer Oberfolie 13a sowie einer Formschulter 14 zum Herumformen der Oberfolie um den zu verpackenden Teilstapel 4a herum angedeutet ist.In the exemplary embodiment shown, a film wrapping machine is provided as a further processing machine, the product inlet of which is indicated with guide rollers 12 and 12a for feeding a lower film 13 and an upper film 13a and a shape shoulder 14 for shaping the upper film around the partial stack 4a to be packaged.

Unterhalb der Stapelauflage 1 sind an einem Tragrahmen 16 Umlenkrollen 17 gelagert, um welche als Entnahmeförderer ein Endlosförderer 18,beispielsweise in Gestalt einer umlaufenden Kette, mit Mitnehmern 19 geführt ist. Wie die Fig. 2 zeigt, weist die Stapelauflage 1 in Förderrichtung 6 parallel verlaufende Schlitze 21 auf, durch welche die Mitnehmer 19 nacheinander in das Stapelprofil des Stapels 2 hineinragen. Der Antrieb des Endlosförderers 18 erfolgt über einer Riementrieb 22, der über Umlenkrollen 22a sowie eine Antriebsrolle 22b geführt ist. Der Antrieb erfolgt mittels eines Motors 23. Der Tragrahmen 16 ruht auf Stützen 24, die im Maschinengestell 26 höhenverstellbar geführt sind. An Querträgern 27 des Tragrahmens 16 sind Betätigungsstangen 28 angebracht, deren untere Enden als Zahnstangen 28a ausgebildet sind. Mit den Zahnstangen 28a stehen Ritzel 29 in Eingriff, die über eine Achse 31 gemeinsam von einem Motor 32 angetrieben werden. Bei ent­sprechender stabiler Ausführung der Betätigungsstangen 28 können diese auch gleichzeitig die Führungsfunktionen der Stützen 24 übernehmen, so daß auf diese verzichtet werden kann und der Tragrahmen 16 von den Betätigungs­stangen 28 getragen wird. Andererseits ist es auch möglich, die seitlichen Stützen 24 für die Höhenverstellung des Tragrahmens zu nutzen, so daß separate Betätigungsstangen 28 entfallen können. Dies ist in Fig. 2 durch ein einer der Stützen 24 zugeordnetes Ritzel 29a angedeutet.Below the stack support 1, 16 deflection rollers 17 are mounted on a support frame, around which an endless conveyor 18, for example in the form of a revolving chain, is guided with drivers 19 as a removal conveyor. As FIG. 2 shows, the stack support 1 has slots 21 running parallel in the conveying direction 6, through which the drivers 19 successively protrude into the stack profile of the stack 2. The endless conveyor 18 is driven by a belt drive 22, which is guided via deflection rollers 22a and a drive roller 22b. The drive takes place by means of a motor 23. The support frame 16 rests Supports 24, which are guided in a height-adjustable manner in the machine frame 26. Actuating bars 28 are attached to cross members 27 of the supporting frame 16, the lower ends of which are designed as toothed bars 28a. Pinions 29 are in engagement with the toothed racks 28a and are driven jointly by an engine 32 via an axis 31. With a correspondingly stable design of the actuating rods 28, they can also assume the guiding functions of the supports 24 at the same time, so that they can be dispensed with and the support frame 16 is carried by the actuating rods 28. On the other hand, it is also possible to use the side supports 24 for the height adjustment of the support frame, so that separate actuating rods 28 can be omitted. This is indicated in FIG. 2 by a pinion 29a assigned to one of the supports 24.

Durch einfaches Verstellen der Höhe des Tragrahmens 16 mit dem Endlosförderer 18 mittels des Antriebes 32 relativ zur stationären Stapelauflage 1 kann die Greifhöhe der Mitnehmer 19 oberhalb der Stapelauflage auf eine gewünschte Gegenstandshöhe eingestellt werden. Im vorliegenden Aus­führungsbeispiel ergreifen die Mitnehmer 19 Teilstapel 4 mit jeweils vier aufeinanderliegenden Gegenständen 3 und schieben sie unter der als Rückhalteanschlag 8b dienenden Unterseite der Begrenzungswand 8 hindurch zur Folienein­schlagmaschine 7. Der Rückhalteanschlag 8b ist mittels des Antriebs 11 so eingestellt, daß er den gewünschten Teilstapel 4 passieren läßt, den daraufliegenden nächsten Gegenstand 3 aber zurückhält. Durch Verstellung der vor­deren Begrenzungswand 8 und der Greifhöhe der Mitnehmer 19 ist also eine gezielte Dosierung der Entnahme vom Stapel 2 möglich. Die Höhenverstellbarkeit der Mitnehmer 19 erlaubt es auch, diese so einzustellen, daß sie un­mittelbar in den Einlaufbereich der anschließenden Verarbeitungsmaschine hineinbewegt werden können, auch wenn dort höhenbegrenzende Führungen, wie beispielsweise die Formatschulter 14 in der Darstellung der Fig. 1, vorgesehen sind.By simply adjusting the height of the support frame 16 with the endless conveyor 18 by means of the drive 32 relative to the stationary stack support 1, the gripping height of the drivers 19 above the stack support can be adjusted to a desired object height. In the present exemplary embodiment, the drivers 19 take partial stacks 4, each with four superimposed objects 3, and push them under the underside of the boundary wall 8, which serves as a retaining stop 8b, to the film wrapping machine 7 lets pass, but holds back the next object 3 lying thereon. By adjusting the front boundary wall 8 and the gripping height of the driver 19, a targeted metering of the removal from the stack 2 is possible. The height adjustability of the driver 19 also allows it to be set so that it directly into the inlet area of the subsequent Processing machine can be moved, even if there are height-limiting guides, such as the format shoulder 14 in the illustration of FIG. 1, are provided.

Zur Darstellung der Höhenverstellbarkeit des Tragrahmens 16 mit dem Endlosförderer 18 sind hier Zahnstangen und Ritzel beschrieben. Es ist selbstverständlich, daß für die Höhenverstellung des Tragrahmens und die Greifhöhen­einstellung der Mitnehmer beliebige andere Verstellmittel eingesetzt werden können. Die Erfindung ist von diesen Verstellmitteln nicht abhängig. Anstelle der motorischen Antriebe 11 und 32 können natürlich auch handbetätigte Antriebe benutzt werden.To illustrate the height adjustability of the support frame 16 with the endless conveyor 18 racks and pinions are described here. It goes without saying that any other adjustment means can be used for the height adjustment of the support frame and the gripping height adjustment of the drivers. The invention is not dependent on these adjustment means. Instead of the motor drives 11 and 32, of course, manually operated drives can also be used.
