Abstract

An apparatus for the stack formation is described, by means of which a practically continuous individual stack formation is possible from a stream of slices produced by means of a cutting apparatus. For this purpose a partial stack is formed by means of a stack receiver, and is transferred for the further stack formation to a portioning band, so that, during the continuation of the stack formation on the portioning band, a return guidance of the stack receiver can take place into a position from which it can be shot anew into the stream of slices for the formation of a next partial stack.

Description

Die Erfindung betrifft eine Vorrichtung zur Bildung von Stapeln von in schneller Folge scheibenförmig aufgeschnittenen Produkten, insbesondere Lebensmittelprodukten wie Schinken, Wurst, Käse und dergleichen, mit einem einer Schneideinrichtung, insbesondere einem Slicer zugeordneten Portionierband und einem den jeweils fertigen Stapel vom Portionierband übernehmenden Transportband.The invention relates to a device for forming stacks of sliced in rapid succession Products, especially food products such as ham, Sausage, cheese and the like, with a cutting device, in particular a portioning belt assigned to a slicer and one each of the finished batches from the portioning belt receiving conveyor belt.

Es ist bekannt, Lebensmittelprodukte mittels Slicern, das heißt Schneidevorrichtungen mit hoher Schnittfrequenz, zu Scheibenstapeln aufzuschneiden, wobei in Abhängigkeit von dem sich bildenden Stapel die Fallhöhe der einzelnen vom Produkt abgetrennten Scheiben unterschiedlich ist. Diese unterschiedliche Fallhöhe führt dazu, daß kein ausreichend exakt ausgerichteter Vertikalstapel entsteht, sondern bezogen auf das den Stapel im Regelfall aufnehmende und während der Stapelbildung stillstehende Transportband ein Versatz in Transportbandrichtung sowie ein seitlicher Versatz auftritt. Dem in Transportbandrichtung auftretenden Versatz kann durch entsprechende Steuerung des Transportbandes entgegengewirkt werden, aber der seitliche Versatz, der von einer an der jeweiligen Scheibe durch das Schneidmesser mitgeteilten Bewegungskomponente herrührt, läßt sich nicht oder nur unter Inkaufnahme anderweitiger Nachteile kompensieren.It is known to slicer food products that means cutting devices with a high cutting frequency Slice up slices, depending on the forming pile the drop height of each from the product separated slices is different. This different Fall height means that no one is sufficiently precise aligned vertical stack is created, but related to the one that normally picks up the stack and during the stack formation stationary conveyor belt an offset in the conveyor belt direction as well as a lateral offset occurs. The offset occurring in the direction of the conveyor belt can be compensated for by appropriate Control of the conveyor belt can be counteracted, but the lateral offset from one to the other Slice of motion component communicated by the cutting knife originates, can not or only with acceptance compensate for other disadvantages.

Es ist bereits bekannt, zur Erzielung einer im wesentlichen konstanten Fallhöhe der Einzelscheiben die Stapelbildung auf einem absenkbaren Portionierband vorzunehmen. Da das Portionierband nach Übergabe eines fertigen Stapels an das Transportband zur Bildung des nächsten Stapels erst wieder in seine messernahe Ausgangsposition zurückgefahren werden muß, ergeben sich zwischen den einzelnen Stapelbildungsvorgängen vergleichsweise lange Zeitspannen, in denen Leerschnitte ausgeführt werden müssen, was zu erheblichen Leistungseinbußen führt.It is already known to achieve one essentially constant drop height of the individual slices on the stack formation a lowerable portioning belt. Because the portioning belt after handing over a finished stack to the conveyor belt to form the next stack again in his knife-near starting position must be returned between the individual stacking processes comparatively long periods of time in which empty cuts are carried out need to be, causing significant performance degradation leads.

Ferner ist es bereits bekannt, sogenannte Paddelanordnungen zur Stapelbildung zu verwenden, die während der Stapelbildung abgesenkt werden und den jeweils fertigen Stapel auf ein Transportband übergeben. Die bekannte Paddelanordnung ist konstruktiv aufwendig und nicht geeignet, die Anforderungen an die hohen Arbeitsgeschwindigkeiten und Arbeitsgenauigkeiten bei den immer leistungsfahiger werdenden Slicern zu erfüllen.Furthermore, it is already known, so-called paddle arrangements to use for stacking during stacking be lowered and the respective finished stack on one Hand over the conveyor belt. The well-known paddle arrangement is structurally complex and not suitable, the requirements to the high working speeds and working accuracy to meet with the increasingly powerful slicers.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs angegebenen Art in der Weise auszubilden, daß auch bei sehr hohen Schnittgeschwindigkeiten eine kontinuierliche Stapelbildung ermöglicht und während der Stapelbildung ein seitlicher Versatz zumindest weitestgehend vermieden wird.The object of the invention is a device of the beginning specified type in such a way that even with very high cutting speeds a continuous stack formation allows and during stacking a side Offset is at least largely avoided.

Gelöst wird diese Aufgabe nach der Erfindung dadurch, daß zwischen der Schneideinrichtung und dem Portionierband ein während der Bildung eines Teilstapels absenkbarer und nach Übergabe des Teilstapels auf das Portionierband in eine schneidmessernahe Warteposition rückführbarer Stapelaufnehmer vorgesehen ist, daß das Portionierband entsprechend der weiteren Stapelbildung und zumindest zwischen der Teilstapel-Übernahmeposition und einer Fertigstapel-Übergabeposition absenkbar ist, und daß der Stapelaufnehmer zur Bildung des jeweils nächsten Teilstapels aus der Warteposition in den von der Schneidvorrichtung erzeugten Scheibenstrom einschießbar ist.This object is achieved according to the invention in that between the cutting device and the portioning belt during the formation of a partial stack lowerable and after Transfer of the partial stack to the portioning belt in a Waiting position traceable stack picker near the cutting knife it is provided that the portioning belt according to the other Stack formation and at least between the partial stack transfer position and a finished stack transfer position can be lowered is, and that the stack sensor to form the respective next partial stack from the waiting position in the of the slice current generated by the cutting device is.

Aufgrund der mittels des Stapelaufnehmers erfolgenden Teilstapelbildung und die nach Übergabe des Teilstapels auf das Portionierband erfolgende Rückführung des Stapelaufnehmers in eine Position, aus der er zu einem vorgebbaren Zeitpunkt blitzschnell in den Scheibenstrom einschießbar ist und damit die Bildung eines neuen Teilstapels erfolgt, muß im Zusammenhang mit der aufeinanderfolgenden Stapelbildung kein für die Rückführung des Stapelaufnehmers erforderlicher Zeitverlust in Kauf genommen werden, was Voraussetzung dafür ist, daß die Stapelbildung bevorzugt leerschnittfrei durchgeführt werden kann. Eine leerschnittfreie Stapelbildung hat auch zur Folge, daß die Schneidvorrichtung optimal betrieben werden kann und kein Anhalten des Produktvorschubs bzw. kein teilweises Rückziehen des Produkts bezüglich der Schneidebene erfolgen muß.Because of the partial stack formation that takes place by means of the stack pickup and after handing over the partial stack to the Portioning belt of the batch sensor in a position from which he is at a predetermined time can be shot into the disk stream at lightning speed and thus the formation of a new sub-stack must be related with the sequential stacking no for the Return of the batch sensor required loss of time be accepted, which is a prerequisite for the Stack formation should preferably be carried out free of empty cuts can. An empty cut-free stack formation also has the consequence that the cutting device can be operated optimally and no stopping of the product feed or no partial Retract the product with respect to the cutting plane got to.

Von Bedeutung ist auch, daß mittels der erfindungsgemäßen Vorrichtung problemfrei für alle Einzelscheiben eine gleiche Fallhöhe gewährleistet werden kann und dabei die Fallhöhe minimal wählbar ist, da die über den Stapelaufnehmer erfolgende Teilstapelbildung unmittelbar angrenzend der tiefsten Position der Schneidkante des Messers erfolgen kann.It is also important that by means of the invention Device problem-free for all individual panes the same Fall height can be guaranteed and the fall height minimal is selectable because the one that takes place via the stack pickup Partial stack formation immediately adjacent to the lowest position the cutting edge of the knife can be done.

Bevorzugt ist das Portionierband, auf das der mittels des Stapelaufnehmers gebildete Teilstapel übergeben wird, als Riemenband ausgebildet, in das der entsprechend angepaßt rechenartig ausgebildete Stapelaufnehmer eintauchen und während dieses Eintauchvorgangs den Teilstapel auf das Portionierband übergeben kann. Die weitere Stapelbildung erfolgt bis zur Fertigstellung des endgültigen Stapels durch entsprechendes Absenken des Portionierbandes, wobei die Absenkbewegungen von Stapelaufnehmer und Portionierband einander entsprechen, so daß sich während der Gesamtstapelbildung keine Veränderung der Fallhöhe der Einzelscheiben ergibt.The portioning belt onto which the by means of the Stack pickup formed part stack is passed as Strap formed into which the appropriately adapted rake-like immerse trained stackers and while this immersion process the partial stack on the portioning belt can pass. The further stacking takes place until Completion of the final stack by the corresponding Lowering the portioning belt, the lowering movements of Stack picker and portioning belt correspond to each other, see above that there is no change during the overall stack formation the drop height of the individual panes.

Die Portionierbandabsenkung ist bevorzugt so gestaltet, daß das Portionierband zur Vergrößerung der Einschußlücke für den Stapelaufnehmer bei Erreichen der dem Fertigstapel entsprechenden Position kurzzeitig beschleunigt absenkbar ist. Das Ausmaß dieser beschleunigten Absenkung kann dabei gering sein, da der Stapelaufnehmer beispielsweise über einen Spindeltrieb mit programmierbarem Bewegungsverlauf innerhalb von Millisekunden aus der Warteposition in die aktive Position überführt werden kann.The portioning belt lowering is preferably designed so that the portioning belt to enlarge the bullet gap for the Stack picker when the one corresponding to the finished stack is reached Position can be lowered quickly accelerated. The The extent of this accelerated lowering can be small be because the stack pickup, for example, via a spindle drive with programmable movement within Milliseconds from the waiting position to the active position can be transferred.

Besonders vorteilhaft ist es ferner, wenn der Absenkhub des Stapelaufnehmers fest und der Absenkhub des Portionierbandes in Abhängigkeit von der jeweils geforderten Stapelhöhe einstellbar ist, da auf diese Weise der Gesamt-Bewegungsverlauf des Stapelaufnehmers fest vorgegeben werden kann und dennoch hinsichtlich der Stapelbildung die erforderliche Variabilität gegeben ist.It is also particularly advantageous if the lowering stroke of the Stack sensor and the lowering stroke of the portioning belt adjustable depending on the stack height required is because in this way the overall course of movement the stack picker can be fixed and still the required variability in terms of stack formation given is.

Weitere besonders vorteilhafte Merkmale der Erfindung sind in den Unteransprüchen angegeben.Further particularly advantageous features of the invention are in specified in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung erläutert, wobei die Figuren 1 bis 7 in schematischer Weise zum einen den prinzipiellen Grundaufbau der erfindungsgemäßen Vorrichtung und zum anderen den Vorgang der Stapelbildung in der Reihenfolge der aufeinanderfolgenden Betriebszustände der Vorrichtung erkennen lassen.An embodiment of the invention is described below Explained with reference to the drawing, wherein the figures to 7 in a schematic way on the one hand the principle Basic structure of the device according to the invention and on the other the process of stacking in the order of successive Show operating conditions of the device.

Figur 1 zeigt in schematischer Weise eine Schneidvorrichtung 1 mit einem rotierenden Sichelmesser oder einem rotierenden und gleichzeitig planetarisch umlaufenden Messer 8 sowie einem über eine herkömmliche Produktzuführung der Schneidebene zugeführten, aufzuschneidenden Produkt 7. Mittels einer derartigen, auch als Slicer bezeichneten Schneidvorrichtung, die eine Schneidleistung von weit über tausend Schnitten pro Minute besitzen kann, wird aus dem aufzuschneidenden Produkt ein Strom von nach unten fallenden Einzelscheiben erzeugt. Aus diesen Einzelscheiben müssen in vielen Fällen Scheibenstapel gebildet werden, wobei die Scheiben im Stapel möglichst exakt gegenseitig ausgerichtet sein sollen, so daß sich keine Stapelschiefstellungen ergeben.Figure 1 shows a cutting device in a schematic manner 1 with a rotating sickle knife or a rotating one and at the same time planetary revolving knife 8 as well one via a conventional product feed of the cutting plane supplied, to be sliced product 7. By means of a such a cutting device, also called a slicer, which have a cutting performance of well over a thousand cuts per minute can be cut from the Product generates a stream of single disks falling down. In many cases, these individual disks must Disc stacks are formed, with the discs in the stack should be aligned with one another as precisely as possible, so that there are no stacking misalignments.

Unterhalb der Schneidvorrichtung 1 ist ein Portionierband 2 vorgesehen, das im Regelfall aus einem sogenannten Riemenband, das heißt einem aus einer Mehrzahl gegenseitig beabstandeter, um Umlenkrollen geführter Einzelriemen besteht. Auf diesem Portionierband 2 muß der jeweilige Stapel von Scheiben gebildet werden. Das Portionierband 2 ist in seiner Höhenlage verstellbar ausgebildet und auch mit einem Antrieb zum Abtransport eines fertigen Stapels versehen. Auf das Portionierband 2 folgt ein Transportband 5, das fertige Stapel vom Portionierband 2 übernimmt.Below the cutting device 1 is a portioning belt 2 provided that usually consists of a so-called belt band, that is, one of a plurality of mutually spaced individual belts guided around deflection rollers. On this portioning belt 2, the respective stack of Discs are formed. The portioning belt 2 is in his Height adjustable and also with a drive provided for the removal of a finished stack. On the Portioning belt 2 is followed by a conveyor belt 5, the finished stack from portioning belt 2.

Zwischen der Schneidvorrichtung 1 und dem Portionierband 2 ist ein Stapelaufnehmer 6 vorgesehen, der als rechenartiges Organ ausgebildet und dabei so bemessen ist, daß er zwischen die Einzelbänder des Portionierbandes 2 eintauchen kann.Between the cutting device 1 and the portioning belt 2 a stack pickup 6 is provided, which is a rake-like Organ trained and is dimensioned so that he between the individual belts of the portioning belt 2 can be immersed.

Der Stapelaufnehmer 6 ist entsprechend einer vorgebbaren Bewegungsbahn verfahrbar, was im einzelnen noch bei der Funktionsbeschreibung erläutert wird.The stack sensor 6 is in accordance with a predeterminable movement path movable, which is still in the functional description is explained.

In Figur 1 nehmen der Stapelaufnehmer 6 und das Portionierband 2 ihre jeweilige Grundstellung ein, wobei sich der Stapelaufnehmer 6 voll in der Bewegungsbahn der vom Produkt 7 abgetrennten Scheiben befindet und mit seinem messerseitigen Ende in unmittelbarer Nähe der tiefsten Position der Schneidkante des Messers 8 gelegen ist. Mit Beginn des Aufschneidevorgangs wird der Stapelaufnehmer 6 in Richtung des Portionierbandes 2 abgesenkt, und zwar mit solcher Geschwindigkeit, daß die Fallhöhe der Einzelscheiben zumindest im wesentlichen konstant bleibt. Dabei wird auf dem Stapelaufnehmer 6 - wie dies in Figur 2 gezeigt ist - ein Teilstapel 3 gebildet. In Figure 1, the stack pickup 6 and the portioning belt take 2 their respective basic position, the stack pickup 6 fully in the trajectory of the product 7 severed washers and with its knife-side End in the immediate vicinity of the lowest position of the cutting edge the knife 8 is located. At the beginning of the slicing process the stack pickup 6 in the direction of the portioning belt 2 lowered, and at such a speed, that the drop height of the individual discs at least essentially remains constant. It is on the stack 6 - how this is shown in Figure 2 - a partial stack 3 is formed.

Die Größe des Teilstapels ist vorgebbar, und die Teilstapelbildung ist dann beendet, wenn entsprechend der Darstellung in Figur 2 der Stapelaufnehmer 6 den Teilstapel 3 auf das Portionierband 2 übergibt, damit vom Teilstapel 3 frei wird und in Richtung des in Figur 2 gezeigten Pfeils unter dem Teilstapel weggezogen werden kann. Von diesem Moment an erfolgt die weitere Stapelbildung auf dem Portionierband 2, das nunmehr mit entsprechender Geschwindigkeit abgesenkt wird, um die Fallhöhe der Einzelscheiben konstant zu halten. Während der Fortführung der Stapelbildung auf dem Portionierband 2 wird - wie dies in Figur 4 gezeigt ist - der Stapelaufnehmer 6 in Richtung einer Warteposition geführt, die in Figur 5 gezeigt ist. In dieser Position kann der Stapelaufnehmer 6 zur Ruhe kommen, wobei ersichtlich ist, daß für die Rückführung des Stapelaufnehmers 6 in diese Ruheposition während der weiteren Stapelbildung ausreichend Zeit zur Verfügung steht.The size of the partial stack can be specified and the partial stack formation is finished when according to the representation in Figure 2, the stack pickup 6, the partial stack 3 on the Portioning belt 2 passes so that the partial stack 3 is free and in the direction of the arrow shown in Figure 2 under the Partial stack can be pulled away. From that moment onwards the further stack formation on the portioning belt 2, the is now lowered at the appropriate speed to keep the drop height of the individual panes constant. While the continuation of the stack formation on the portioning belt 2 becomes - as shown in Figure 4 - the stack pickup 6 in the direction of a waiting position, which is shown in FIG is shown. In this position, the stack pickup 6 come to rest, whereby it can be seen that for the return of the stack pickup 6 in this rest position during the sufficient time is available for further stack formation.

In Figur 6 ist der Zeitpunkt gezeigt, zu dem der Fertigstapel 4 auf dem Portionierband 2 vorliegt und der Stapelaufnehmer 6 entsprechend dem gezeigten Pfeil mit sehr hoher Geschwindigkeit in den Scheibenstrom eingeschossen wird und innerhalb von Millisekunden in die in Figur 8 gezeigte Position gelangt, die auch bereits in Figur 1 dargestellt ist und dem Beginn der nächsten Teilstapelbildung entspricht.FIG. 6 shows the time at which the finished stack 4 is present on the portioning belt 2 and the stack pickup 6 according to the arrow shown at very high speed is injected into the disk stream and within of milliseconds to the position shown in FIG arrives, which is also already shown in Figure 1 and the Corresponds to the beginning of the next partial stack formation.

Während dieser Teilstapelbildung kann der fertige Stapel 4 vom Portionierband 2 auf das Transportband 5 übergeben werden, das sich mit seinem portionierbandseitigen Ende entsprechend dem Portionierband nach unten bewegt hat, so daß eine problemfreie Übergabe des fertigen Stapels 4 auf das Transportband 5 möglich ist.During this partial stack formation, the finished stack 4 transferred from the portioning belt 2 to the conveyor belt 5, the corresponding with its portion conveyor end the portioning belt has moved down so that a problem-free transfer of the finished stack 4 to the conveyor belt 5 is possible.

Der Stapelbildungsvorgang wiederholt sich dann in der beschriebenen Weise. The stacking process is then repeated in the described Wise.

Je nach den in der Praxis vorliegenden Gegebenheiten kann die Stapelbildung leerschnittfrei erfolgen, aber es ist natürlich auch möglich, zwischen der Beendigung einer Stapelbildung und dem Beginn einer neuen Teilstapelbildung einen Leerschnitt oder wenige Leerschnitte zwischenzuschalten. Dies ändert nichts an dem vorteilhaften Grundprinzip der vorliegenden Erfindung, das im besonderen Zusammenwirken von Stapelaufnehmer und Portionierband zu sehen ist.Depending on the circumstances in practice, the Stacking can be done with no gaps, but it is natural also possible between the completion of a batch and an empty cut at the start of a new partial stack formation or interpose a few empty cuts. This is changing nothing about the advantageous basic principle of the present invention, that in particular the interaction of the stack sensor and portioning belt can be seen.
