Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren nach dem Oberbegriff
des Anspruchs 1 und eine Vorrichtung nach dem Oberbegriff des Anspruchs
5. Ein solches Verfahren und eine solche Vorrichtung sind aus
der US-A-4 709 535 bekannt.The present invention relates to a method according to the preamble
of
Bei üblichen Wurstschneide- und Verpackungsmaschinen werden Lebensmittelprodukte wie Wurst, Fleisch, Käse usw. zunächst mittels einer Schneideeinheit, einem sogenannten Slicer, aufgeschnitten und in vorbestimmten Portionen auf einem Förderband abtransportiert. Da die Schnittgeschwindigkeit solcher Slicer sehr hoch ist, werden die Stapel zur weiteren Verpackung mittels eines Querverteilers im Wechsel an mehrere parallel zueinander verlaufende Gruppierbänder übergeben, auf denen sie dann in einer Reihe nebeneinanderliegend weitertransportiert werden. Von den parallel laufenden Gruppierbändern werden die Stapel gegebenenfalls unter Zwischenschaltung von Pufferbändern an ein breites Einlegeband übergeben, auf dem sie in Reihen nebeneinanderliegend zu einer Verpackungsmaschine transportiert werden, wo sie in nebeneinanderliegende Tiefziehverpackungen eingelegt werden, die in ihrer Anzahl der Anzahl nebeneinanderliegender Stapel entsprechen.In conventional sausage cutting and packaging machines, food products are used such as sausage, meat, cheese etc. first using a Cutting unit, a so-called slicer, cut open and in predetermined portions transported away on a conveyor belt. Since the Cutting speed of such slicers is very high, the stacks alternately for further packaging using a cross distributor hand over several grouping tapes running parallel to each other, on which it is then transported in a row next to each other become. From the grouping tapes running in parallel the stacks, if necessary, with the interposition of buffer belts handed over to a wide inlay tape on which they lie side by side in rows be transported to a packaging machine where they are placed in thermoformed packaging next to each other, which correspond in number to the number of adjacent stacks.
Das Einlegen der aufgeschnittenen Produkte in die Tiefziehverpackungen ist unproblematisch, wenn die aufgeschnittenen scheibenförmigen Produkte in geschindelter Form, das heißt mit Versatz übereinanderliegend, transportiert und verpackt werden. Es treten jedoch Schwierigkeiten auf, wenn die Scheiben der aufgeschnittenen Produkte als senkrecht übereinanderliegende Stapel verpackt werden sollen. Dies liegt zum einen daran, daß es nur sehr schwer möglich ist, die zu verpackenden Produktstapel der Verpackungsmaschine auf dem Einlegeband genau nebeneinanderliegend zu positionieren, so daß sie der Verpackungsmaschine mit Versatz zugeführt werden. Weiterhin liegt beim Einlegen solcher Stapel der Boden der entsprechenden Tiefziehverpackungen relativ weit unterhalb der Zuführkante des Einlegebandes, so daß der Fallweg des Produktes relativ hoch ist. Dies ist insofern problematisch, als die Fallbewegung nicht genau gesteuert werden kann, so daß die Einlegebewegung ungenau wird.The insertion of the cut products into the thermoformed packaging is not a problem if the sliced disc-shaped Products in shingled form, i.e. with an overlapping offset, transported and packed. However, difficulties arise on when the slices of the sliced products as vertical stacked stack should be packed. This is because on the one hand because it is very difficult to pack the Product stack of the packaging machine on the loading belt to be positioned exactly next to each other so that the packaging machine be fed with offset. Furthermore lies with Insert such stacks of the bottom of the appropriate thermoformed packaging relatively far below the feed edge of the insert tape, see above that the fall distance of the product is relatively high. This is problematic in that when the falling movement cannot be controlled precisely, so that the insertion movement becomes inaccurate.
Im Ergebnis ist ein Einlegen von Stapeln von scheibenförmigen Lebensmittelprodukten nur möglich, wenn die Verpackungen ausreichend groß gewählt sind, das heißt hinreichend viel Spielraum gelassen wird, um Positionierungenauigkeiten ausgleichen zu können. Dies führt jedoch zu hohen Materialkosten.As a result, stacks of disc-shaped food products are inserted only possible if the packaging is sufficient are large, that is, there is sufficient scope, to be able to compensate for positioning inaccuracies. However, this leads at high material costs.
Aus der DE-A-30 49 606 ist eine Beschickungsvorrichtung zum Einlegen mehrerer Stapel eines aufgeschnittenen Nahrungsmittels bekannt, bei der die Scheibenstapel von einem Rollenförderer auf eine Ladeplattform gelangen, um anschließend von einem Transportwagen in eine Beschickungsposition zwischen zwei Seitenführungen gebracht zu werden, bevor ein Pneumatikzylinder nach unten fährt und die Scheibenstapel in eine Packungsöffnung drückt. DE-A-30 49 606 describes a loading device for insertion several stacks of a sliced food known in which the disc stack from a roller conveyor to a loading platform then move from a trolley to a loading position to be brought between two side guides before a pneumatic cylinder moves down and the stack of disks presses into a package opening.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Vorrichtung anzugeben, welche die Vermeidung der genannten Nachteile ermöglichen und es gestatten, nebeneinanderliegende Stapel von scheibenförmigen Lebensmittelprodukten in Mulden einer Verpackungsmaschine mit hoher Genauigkeit einzulegen.The object of the present invention is a method and an apparatus specify which of the avoidance of the disadvantages mentioned enable and allow stacked disc-shaped stacks Food products in troughs of a packaging machine insert with high accuracy.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale der Ansprüche 1
und 5. This object is achieved by the features of
Die zugeführten Produktstapel werden zunächst auf Haltern einer Aufnahmeeinrichtung abgelegt. Die Halter der Aufnahmeeinrichtung können dabei dicht unter der Zuführkante des Einlegebandes positioniert werden, wodurch bereits eine hohe Positioniergenauigkeit erreicht wird. Durch die anschließende Zentrierung der Produktstapel auf den Haltern mittels der Zentriereinrichtung nehmen die Stapel eine definierte Lage gegenüber den unter den Aufnahmebereichen positionierten Mulden ein, so daß eine hohe Einlegegenauigkeit erzielt wird, wenn die Stapel nach unten fallen gelassen werden.The product stacks are fed first placed on holders of a receiving device. The holder of the receiving device can be tight be positioned under the feed edge of the insert tape, which already achieves high positioning accuracy becomes. By then centering the product stack on the holders by means of the centering device Stack a defined position in relation to that under the receiving areas positioned troughs, so that a high insertion accuracy is achieved when the stacks fall down be left.
Wenn die Fallbewegung durch Druckelemente einer Einschubeinrichtung unterstützt wird, das heißt die Druckelemente mit einer höheren Geschwindigkeit als die Fallgeschwindigkeit abgesenkt werden und dabei die Produktstapel in die Mulden stoßen, kann verhindert werden, daß die Stapel während der Fallbewegung kippen, wodurch die Einlegegenauigkeit weiter erhöht wird.If the falling movement by pressure elements of an insertion device is supported, i.e. with the printing elements a higher speed than the falling speed are lowered and the product stacks into the troughs bump can be prevented from stacking during the Tilt the fall motion, thereby further increasing the insertion accuracy is increased.
Aufgrund der hohen Einlegegenauigkeit des erfindungsgemäßen Verfahrens sind lediglich kleine Toleranzen erforderlich, so daß die Verpackungen, in die die Stapel eingelegt werden, klein gehalten werden können.Because of the high insertion accuracy of the invention The process only requires small tolerances, so that the packaging in which the stacks are placed can be kept small.
Um die Ablegegenauigkeit noch zu erhöhen, können die Zentrierelemente in vorteilhafter Weise bis an die Oberkante der Mulden verfahren werden, so daß sie eine seitliche Führung für die Produktstapel während der Einlegebewegung bilden, wobei die Reibung des Produktes an den Zentrierelementen eine Kippbewegung von diesem verhindert.The centering elements can be used to increase the placement accuracy advantageously up to the top of the Troughs are moved so that they have a side guide form for the product stack during the insertion movement, whereby the friction of the product on the centering elements prevents a tilting movement of this.

liegt und von dem Einlegeband 8 zugeführte Produktstapel an
dem vorderen Rand der Aufnahmebereiche 13 zum Liegen kommen.
Dann wird der Schlitten 18 parallel zu dem Einlegeband 8 und
mit gleicher Geschwindigkeit entlang der Führung 20 bewegt,
um die Produktstapel vollständig auf den Haltern 14 abzulegen.
Der Vorgang wird für die zweite Reihe von Aufnahmebereichen
13 wiederholt.The
Anschließend wird der Schlitten 18 in seine Entladestellung
gebracht, in der die Aufnahmebereiche 13 direkt oberhalb der
Mulden 10 der Verpackungsmaschine 11 und mittig unterhalb
der ihnen zugeordneten Zentrierstangen 22 und den zwischen
diesen liegenden Einschubteller 28 liegen (vergleiche
Figur 7).Then the
Das Erreichen der Entladestellung wird durch einen nicht dargestellten
Sensor erfaßt, der ein Signal an eine Steuereinrichtung
der Zentriereinrichtung 21 zuführt, woraufhin der
Träger 24 mit den Zentrierstangen 22 und den Einschubtellern
28 abgesenkt wird, bis die an der Tragstange 23 vorgesehene
Justierschraube 25 und die Anschlagsfläche 26 der
Steuereinrichtung aneinanderstoßen. In dieser Stellung liegen
die unteren Enden der Zentrierstangen 22 im Bereich der
Oberkanten der Mulden 10.Reaching the unloading position is indicated by a not shown
Sensor detects a signal to a control device

Auf ein Signal der Steuereinrichtung hin werden die Produktstapel
auf den Haltern 14 ausgerichtet, indem die Zentrierstangen
22 aus ihrer zuvor beschriebenen gekippten Stellung
über die Betätigungseinrichtung und die Tragestange 23 in
die vertikale Stellung geschwenkt werden, in der sie an den
Produktstapeln anliegen und diese zwischen sich zentrieren.Upon a signal from the control device, the product stacks become
aligned on the
Anschließend werden die Halter 14 aus ihrer Haltestellung,
in der sie horizontal in die Aufnahmebereiche 13 hineinragen,
über die Stelleinrichtung 32 und die Stangen 17 nach
unten in die Freigabestellung geschwenkt, in der sie nicht
mehr im Bereich der Aufnahmebereiche 13 liegen. Gleichzeitig
drückt die Zylinder/Kolben-Anordnung 30 das Verbindungselement
29 mit den Einschubtellern 28 relativ zu dem Träger
24 mit einer solchen Geschwindigkeit nach unten, so daß
die Produktstapel beim Wegschwenken der Halter 14 unter seitlicher
Führung durch die Zentrierstangen 22 in die darunterliegenden
Mulden 10 hineingestoßen werden (vergleiche
Figur 9).The
Das Wegschwenken der Halter 14 und das Absenken der Einschubteller
28 braucht nicht zwangsweise gleichzeitig zu erfolgen,
die Einschubteller 28 können beispielsweise auch erst
bis an die Oberkante der Produktstapel abgesenkt werden, bevor
die Halter 14 betätigt werden. Wesentlich ist, daß die
Produktstapel nicht frei fallen, sondern durch die ringförmige
Anlagefläche der Einschubteller 28 an ihrer Oberseite
geführt werden, so daß ein Kippen der Produktstapel beim
Einlegen in die Mulden 10 verhindert wird.The pivoting away of the
Anschließend werden die gefüllten Mulden 10 durch leere ersetzt,
die Einschubteller 28 mittels der Zylinder/Kolben-Anordnung
30 angehoben, die Zentrierstangen 22 nach außen gekippt
und der Träger 24 in seine obere Endstellung bewegt,
so daß der Schlitten 18 in seine Ausgangsstellung unterhalb
des Einlegebandes 8 zurückkehren kann, um neue Produktstapel
auf den in die Haltestellung zurückgebrachten Haltern 14 ablegen
