Description

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung einer Verpackung mit einer Verpackungsmulde, in die ein Verpackungsgut einfüllbar und die mit einem Deckel verschlossen ist, wobei mindestens eine formschlüssige Verbindung die Verpackungsmulde mit dem Deckel verbindet und die Verbindung aus einem ersten und einem zweiten Verbindungsmittel besteht.The present invention relates to a method and an apparatus for producing a packaging with a packaging tray into which a packaged product can be filled and which is closed with a lid, wherein at least one positive connection connects the packaging tray with the lid and the connection of a first and a second Connecting means exists.

Verpackungen bestehen in der Regel aus einer Verpackungsmulde, in die das Verpackungsgut, beispielsweise Lebensmittel, einfüllbar ist. Diese Verpackungsmulde wird dann mit einem in der Regel vorgeformten Deckel verschlossen. Um die Abzugskraft des Deckels von der Verpackungsmulde nach dem erstmaligen Öffen zu erhöhen, ist es für die Wiederverschließbarkeit von Vorteil, wenn zwischen dem Deckel und der Verpackungsmulde mindestens eine formschlüssige Verbindung vorhanden ist. Diese formschlüssige Verbindung besteht aus zwei Verbindungselementen, beispielsweise einer Nut und einer Feder, wobei die Feder in die Nut eingeführt wird.Packaging usually consists of a packaging tray, in which the packaged, such as food, can be filled. This packaging tray is then closed with a usually preformed lid. In order to increase the pull-off force of the lid from the packaging tray after the first opening, it is advantageous for the reclosability if at least one positive-locking connection is present between the lid and the packaging tray. This positive connection consists of two connecting elements, for example a groove and a spring, wherein the spring is inserted into the groove.

Derzeit werden die Verbindungselemente beim Tiefziehen in den Deckel bzw. in die Verpackungsmulde eingeformt. Da der Deckel bzw. die Verpackungsmulde jedoch nach dem Tiefziehen wieder aus dem jeweiligen Tiefziehwerkzeug entformbar und ein Verbindungselement in das andere einführbar sein muss, ist man bei diesem Verfahren bezüglich der Form der Verbindungselemente sehr stark eingeschränkt.Currently, the fasteners are formed during deep drawing in the lid or in the packaging tray. However, since the lid or the packaging tray must again be removed from the respective thermoforming tool after deep drawing and a connecting element must be inserted into the other, one is very limited in this method with respect to the shape of the connecting elements.

Verpackungen, bei denen die formschlüssige Verbindung zwischen dem Deckel und der Verpackungsmulde nach dem Verschließen der Verpackungs mulde mit dem Deckel eingeformt wird, sind aus der US 1.709 , 196 , der DE 1461797 , der EP 0791538A1 und der EP 1493683 bekannt.Packaging in which the positive connection between the lid and the packaging tray after closing the packaging trough is molded with the lid, are from the US 1,709 . 196 , of the DE 1461797 , of the EP 0791538A1 and the EP 1493683 known.

Es war deshalb die Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zur Herstellung solcher Verpackungen zur Verfügung zu stellen.It was therefore the object of the present invention to provide a method and an apparatus for producing such packages.

Die Verpackung besteht aus einer Verpackungsmulde, in die das Verpackungsgut einfüllbar ist,und einem Deckel. Vorzugsweise sind sowohl die Verpackungsmulde als auch der Deckel aus einem Kunststoffmaterial gefertigt und jeweils tiefgezogen. Das Kunststoffmaterial kann vergleichsweise steif und/oder geschäumt sein. Zwischen dem Deckel und der Verpackungsmulde ist mindestens eine, vorzugsweise jedoch mehrere, formschlüssige Verbindungen angeordnet, wobei der Formschluss so wirkt, dass die Kraft, die benötigt wird, um den Deckel von der Verpackungsmulde zu lösen, erhöht wird. Die formschlüssigen Verbindungen können beliebig über den Umfang der Verpackung verteilt sein. Des weiteren können die formschlüssigen Verbindungen mit einem Gelenk kombiniert werden, wobei mindestens eine formschlüssige Verbindung dann gegenüber dem Scharnier(Gelenk) angeordnet ist. Des weiteren können die formschlüssigen Verbindungen auch als Schnappverbindungen für den Wiederverschluss der Verpackungen verwendet werden. Die formschlüssige Verbindung besteht aus einem ersten und einem zweiten Verbindungsmittel, die ineinander greifen und somit die formschlüssige Verbindung bewirken. Als Verbindungselemente kommen alle dem Fachmann geläufigen Verbindungselemente in Frage, mit denen es möglich ist, einen Formschluss zwischen der Verpackungsmulde und dem Deckel zu erzielen. Vorzugsweise handelt es sich bei dem Verbindungselement jedoch um eine Nut-Feder-Verbindung oder um zwei Kugelteilschalen, die ineinander greifen. Vorzugsweise erstreckt sich die Verbindung parallel zur Transportrichtung der Folienbahn, aus der die Verpackungsmulde hergestellt wird. Diese Ausführungsform der vorliegenden Erfindung vereinfacht die Werkzeuge bzw. deren Anordnung in einer Verpackungsmaschine, die benötigt werden, um die Verbindungselemente der formschlüssigen Verbindung in die Verpackungsmulde bzw. den Deckel einzuformen.The packaging consists of a packaging tray, in which the packaged goods can be filled, and a lid. Preferably, both the packaging tray and the lid are made of a plastic material and each deep-drawn. The plastic material may be comparatively stiff and / or foamed. At least one, but preferably a plurality of form-fitting connections are arranged between the cover and the packaging trough, wherein the positive connection acts in such a way that the force required to release the lid from the packaging trough is increased. The positive connections can be distributed as desired over the circumference of the package. Furthermore, the positive connections can be combined with a joint, wherein at least one positive connection is then arranged opposite the hinge (hinge). Furthermore, the positive connections can also be used as snap connections for the reclosure of the packages. The positive connection consists of a first and a second connecting means, which engage in one another and thus effect the positive connection. As connecting elements all known in the art connecting elements in question, with which it is possible to achieve a positive connection between the packaging tray and the lid. Preferably, however, the connecting element is a tongue and groove connection or two partial ball shells, which engage in each other. Preferably, the connection extends parallel to the transport direction of the film web, from which the packaging tray is made. This embodiment of the present invention simplifies the tools or their arrangement in a packaging machine, which are needed to mold the connecting elements of the positive connection in the packaging tray or the lid.

Die Verpackung weist mindestens eine, vorzugsweise jedoch zwei oder mehrere, formschlüssige Verbindungen auf.The packaging has at least one, but preferably two or more, form-fitting connections.

Vorzugsweise sind der Deckel und die Verpackungsmulde im Bereich einer Siegelebene aneinander gesiegelt. Vorzugsweise ist diese Siegelung peelbar, so dass die Verpackung mittels der formschlüssigen Verbindung wieder verschließbar ist.Preferably, the lid and the packaging tray are sealed together in the region of a sealing plane. Preferably, this seal is peelable, so that the packaging can be closed again by means of the positive connection.

Die Verbindungen sind, vorzugsweise durch Thermoformen in die Verpackungsmulde eingebracht. Vorzugsweise erfolgt das Einbringen der Verbindung von Innen nach Außen; d.h. im Bereich der Verbindung vergrößert sich der Umfang der Verpackung. Diese Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass die Fläche, durch die das Verpackungsgut entnommen werden kann durch die Einformungen nicht reduziert wird oder dass zusätzliche Ausbuchtungen hergestellt werden müssen, in die die Verbindungen dann eingeformt werden, wie es beispielsweise in der EP 0 367 603 A2 offenbart ist.The compounds are introduced, preferably by thermoforming in the packaging tray. Preferably, the introduction of the compound takes place from inside to outside; ie in the area of the connection, the size of the packaging increases. This embodiment of the present invention has the advantage that the area through which the packaged goods can be removed by the recesses is not reduced or that additional bulges must be produced, in which the compounds are then molded, as for example in the EP 0 367 603 A2 is disclosed.

Vorzugsweise befindet sich die Einformung in den Seitenwänden der Verpackungsmulde.Preferably, the indentation is located in the side walls of the packaging tray.

Vorzugsweise ist der Deckel an die Verpackungsmulde gesiegelt. Diese Siegelung ist vorzugsweise peelbar, so dass die Verbindung nach erstmaligem Öffen der Verpackung als Wiederverschluss dient. Vorzugsweise ist der Deckel entlang einer im wesentlichen horizontalen Siegelebene an die Verpackungsmulde gesiegelt.Preferably, the lid is sealed to the packaging tray. This seal is preferably peelable, so that the connection serves as a reclosure after first opening the packaging. Preferably, the lid is sealed to the packaging tray along a substantially horizontal sealing plane.

Bei den Verpackungen kann es um beliebig geformte Verpackungen handeln. Vorzugsweise welsen die Verpackungen jedoch im wesentlichen eine viereckige oder runde Grundfläche auf.The packaging may be any shaped packaging. Preferably, however, the packages essentially whip up a square or round base.

Gelöst wird die Aufgabe mit einem Verfahren nach Patentanspruch 1.The problem is solved by a method according to claim 1.

Mit dem erfindungsgemäßen Verfahren ist es möglich, Verpackungen herzustellen, die beliebig geformte formschlüssige Verbindungen zwischen der Verpackung und dem Deckel aufweist. Das erfindungsgemäße Verfahren ist einfach und kostengünstig durchzuführen.With the method according to the invention, it is possible to produce packages having arbitrarily shaped form-fitting connections between the packaging and the lid. The inventive method is simple and inexpensive to perform.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird der Deckel an die Verpackungsmulde gesiegelt, bevor die formschlüssige Verbindung hergestellt worden ist. Vorzugsweise ist die Siegelung peelbar.In a preferred embodiment of the inventive method, the lid is sealed to the packaging tray before the positive connection has been established. Preferably, the seal is peelable.

Vorzugsweise erfolgt die Herstellung der Verpackung taktweise; d.h. immer ein Format bestehend aus mehreren Verpackungen werden taktweise entlang einer Verpackungsmaschine transportiert. Das Einformen der Verbindungen erfolgt dann während eines Stillstandes der herzustellenden Verpackungen. Dafür wird vorzugsweise ein Werkzeug vertikal verschoben, das mindestens ein, vorzugsweise mehrere Prägemittel aufweist. Mit diesen Prägemitteln werden die Verbindungen hergestellt.Preferably, the production of the packaging takes place cyclically; i.e. always a format consisting of several packages are transported intermittently along a packaging machine. The shaping of the compounds then takes place during a standstill of the packaging to be produced. For this purpose, a tool is preferably moved vertically, which has at least one, preferably a plurality of embossing means. With these embossing agents, the compounds are produced.

Zur eigentlichen Herstellung der Verbindungen werden die Prägemittel dafür vorzugsweise quer zur Transportrichtung der Verpackungen entlang der Verpackungsmaschine verschoben und formen dadurch die Verbindung in die Verpackungsmulde bzw. den Deckel ein. Nach der Herstellung werden die Prägemittel wieder eingezogen und vertikal nach oben bewegt, so dass die Verpackungen um einen Takt weitertransportiert werden können.For the actual production of the compounds, the embossing means for this are preferably displaced transversely to the transport direction of the packaging along the packaging machine and thereby form the connection into the packaging trough or the lid. After production, the embossing means are retracted and moved vertically upwards, so that the packages can be transported by one clock.

Erfindungsgemäß wirken die Prägemittel mit einem Gegenlager zusammen, beispielsweise um zu vermeiden, dass sich die Verpackung beim Einformen der Verbindung verzieht.According to the invention, the embossing means cooperate with an abutment, for example in order to avoid that the packaging warps when forming the compound.

Die Gegenlager sind vertikal verschiebbar angeordnet. Sobald sich die Verpackungen unterhalb der Prägemittel befinden, werden die Gegenlager hochgefahren, so dass die an den Verpackungsmulden anliegen. Bevor die Verpackungen weitertransportiert werden, werden die Gegenlager wieder abgesenkt.The counter bearings are arranged vertically displaceable. As soon as the packages are below the embossing means, the counter bearings are raised so that they rest against the packaging troughs. Before the packages are transported on, the counter bearings are lowered again.

Erfindungsgemäß werden die Gegenlager vor dem Absenken verdreht. Weiterhin wird die Aufgabe durch eine Verpackungsmaschine nach Anspruch 4 gelöst.According to the counter-bearings are rotated before lowering. Furthermore, the object is achieved by a packaging machine according to claim 4.

Vorzugsweise ist das Prägemittel quer zur Transportrichtung der Folienbahn verschiebbar gelagert, so dass es reversibel in Eingriff mit der Verpackungsmulde bzw. dem Deckel bringbar ist. Weiterhin ist es vertikal verschiebbar angeordnet, damit es nach dem Einformen der Verbindung aus dem Bereich der Verpackung entfernt werden kann.Preferably, the embossing means is displaceably mounted transversely to the transport direction of the film web, so that it can be brought reversibly into engagement with the packaging trough or the lid. Furthermore, it is arranged vertically displaceable, so that it can be removed after molding of the compound from the region of the package.

Vorzugsweise arbeitet die erfindungsgemäße Verpackungsmaschine taktweise. Die Verpackungen eines Formates werden dabei immer um eine gewisse Wegstrecke taktweise weitertransportiert. Die Bearbeitung der Verpackung wie auch das Einformen der Verbindung erfolgt während des Stillstands der Verpackungen.Preferably, the packaging machine according to the invention operates intermittently. The packages of a format are always transported intermittently by a certain distance. The processing of the packaging as well as the molding of the connection takes place during the stoppage of the packaging.

Weiterhin weist die erfindungsgemäße Verpackungsmaschine Gegenlager auf, mit denen die Prägemittel zusammenwirken. Durch diese Ausführung der vorliegenden Erfindung können die Verbindungselemente der formschlüssigen Verbindung schneller und exakter in die Verpackungsmulde bzw. in den Deckel eingeformt werden. Des weiter wird ein Verziehen der Verpackung während der Herstellung der Verbindung vermieden.Furthermore, the packaging machine according to the invention has counter bearings with which the embossing means interact. Through this embodiment of the present invention, the connecting elements of the positive connection can be formed faster and more accurately in the packaging tray or in the lid. Further, distortion of the package during manufacture of the connection is avoided.

Diese Gegenlager sind vertikal verschiebbar angeordnet. Erfindungsgemäß werden die Gegenlager vor dem Absenken um eine vertikale Achse gedreht, bis eine in dem Gegenlager vorhandene Ausnehmung deckungsgleich mit der eingeformten Verbindung ist. Sodann ist ein problemloses Absenken der Gegenlager möglich.These abutments are arranged vertically displaceable. According to the invention, the counter bearings are rotated about a vertical axis before lowering, until a present in the abutment recess coincides with the molded Connection is. Then a problem-free lowering of the counter bearing is possible.

In Figur 1 ist eine Verpackung dargestellt, die aus einer Vorpackungsmulde 2 und einem Deckel 3 besteht. In die Verpackungsmulde 2 kann ein Verpackungsgut, beispielsweise Lebensmittel, eingelegt werden. Die Vorpackungsmulde 2 wird sodann mit dem Deckel 3 verschlossen. Nachdem die Verpackungsmulde mit dem Deckel verschlossen worden ist, wird die formschlüssige Verbindung 4 in den Deckel und/oder in die Verpackungsmulde eingeformt. Im vorliegenden Fall wird die formschlüssige Verbindung sowohl in den Deckel 3 als auch in die Verpackungsmulde 2 eingeformt. Die Verpackung wird auf einer Verpackungsmaschine hergestellt, wobei die Verpackungsmulde und der Deckel entweder als fertig geformte Teile in die Verpackungsmaschine eingelegt oder beispielsweise durch Tiefziehen in eine plane Folienbahn eingeformt werden. In jedem Fall werden die Verpackungen entlang der durch den Pfeil dargestellten Laufrichtung Innerhalb der Verpackungsmaschine, vorzugsweise taktweise, transportiert. Der Fachmann erkennt, dass in dem vorliegenden Fall die formschlüssige Verbindung 4 parallel zu der Laufrichtung der Verpackungsmaschine angeordnet ist, was die Gestaltung der Verpackungsmaschine erheblich vereinfacht, was anhand der Figuren 3 und 4 näher erläutert wird. Der Deckel und die Verpackungsmulde werden im Bereich der Siegelebene peelbar aneinander gesiegelt, bevor die formschlüssige Verbindung in die Verpackung eingeformt worden ist.In FIG. 1 a package is shown, which consists of a Vorpackungsmulde 2 and a lid 3. In the packaging tray 2, a packaged goods, such as food, are inserted. The Vorpackungsmulde 2 is then closed with the lid 3. after the Packaging tray has been closed with the lid, the positive connection 4 is formed in the lid and / or in the packaging tray. In the present case, the positive connection is formed both in the lid 3 and in the packaging tray 2. The packaging is produced on a packaging machine, wherein the packaging tray and the lid are either inserted as finished molded parts in the packaging machine or molded for example by deep drawing in a flat film web. In any case, the packages are transported along the direction of travel represented by the arrow within the packaging machine, preferably in cycles. The skilled artisan will recognize that in the present case, the positive connection 4 is arranged parallel to the direction of the packaging machine, which greatly simplifies the design of the packaging machine, which is based on the Figures 3 and 4 is explained in more detail. The lid and the packaging tray are peelably sealed together in the region of the sealing plane before the positive connection has been molded into the packaging.

In Figur 2 sind zwei mögliche Gestaltungsformen der formschlüssigen Verbindung dargestellt. In der linken Darstellung ist eine spitz zulaufende Nut gezeichnet, die sich In und aus der Papierebene erstreckt. Dadurch, dass die formschlüssige Verbindung erst in den Deckel bzw. die Verpackungsmulde eingeformt wird, nachdem der Deckel auf die Verpackungsmulde aufgesetzt worden ist, lassen sich Formen der formschlüssigen Verbindung realisieren, die gemäß dem Stand der Technik nicht möglich waren. Beispielsweise war es nicht möglich, eine in der linken Darstellung gezeichnete derart spitze Nut bzw. Feder herzustellen, ohne dass diese entweder nicht mehr entformbar gewesen wäre oder beim Zusammenfügen des Deckels und der Verpackungsmulde nicht beschädigt worden wäre.In FIG. 2 Two possible designs of the positive connection are shown. The left-hand illustration shows a tapered groove extending in and out of the plane of the paper. Characterized in that the positive connection is formed only in the lid or the packaging tray after the lid has been placed on the packaging tray forms of positive connection can be realized, which were not possible according to the prior art. For example, it was not possible to produce such a sharp groove or tongue drawn in the left-hand illustration, without these either no longer being demouldable or not damaged during the assembly of the lid and the packaging tray.

Im rechten Teil der Abbildung 2 ist eine halbkugelförmige Ausgestaltung der formschlüssigen Verbindung dargestellt. Der Fachmann versteht, dass vorteilhafter Welse über den Umfang der Verpackungsmulde verteilt mehrere derartige kugolförmige Formschlussverbindungen angeordnet sind. Im übrigen wird auf die Ausführung zu der linken Ausführungsform gemäß Figur 2 verwiesen.In the right part of the Figure 2 is shown a hemispherical configuration of the positive connection. The person skilled in the art understands that advantageous catfish are distributed over the circumference of the packaging trough and that a plurality of such coaxial positive-fit connections are arranged distributed. Incidentally, the embodiment according to the left embodiment according to FIG. 2 directed.

In Figur 3 ist das Prägemittel einer Verpackungsmaschine dargestellt. Die mit einem Deckel verschlossene Verpackungsmulde (nicht dargestellt) wird in die Papierebene hinein transportiert und in den Aussparungen 12 des Werkzeuges 8 kurzzeitig angehalten. Sobald sich die Verpackung innerhalb der Aussparung 12 in einer stationären Lage befinden, werden die Prägemittel 5, 6, die sich an Verschiebemitteln 9, 10 befinden, abgesenkt und nach rechts bzw. nach links verschoben, so dass sie mit der Verpackung in Eingriff geraten und die jeweiligen Verbindungselemente im wesentlichen gleichzeitig in den Deckel bzw. in die Verpackungsmulde einformen. Während des Einformens wirken die Prägemittel 5, 6 mit Gegenlagem 7, die an dem Werkzeug 8 angeordnet sind, zusammen. Sobald die Verbindungselemente der formschlüssigen Verbindung hergestellt worden sind, werden die Werkzeuge wieder zurückbewegt und die so fertig gestellten Verpackungen werden um einen Takt weiter transportiert. Die Bewegung der Verstellelemente 9, 10 ist durch die beiden Doppelpfeile dargestellt. Die Prägemittel 5, 6 können beheizbar ausgeführt werden.In FIG. 3 the embossing agent of a packaging machine is shown. The sealed with a lid packaging tray (not shown) is transported into the plane of the paper and stopped briefly in the recesses 12 of the tool 8. Once the package is within the recess 12 in a stationary position, the embossing means 5, 6, which are located on displacement means 9, 10, lowered and shifted to the right or to the left, so that they engage with the packaging and molding the respective connecting elements essentially simultaneously into the cover or into the packaging recess. During the shaping, the embossing means 5, 6 interact with abutments 7, which are arranged on the tool 8. As soon as the connecting elements of the positive connection have been produced, the tools are moved back again and the packages thus finished are transported one cycle further. The movement of the adjusting elements 9, 10 is represented by the two double arrows. The embossing means 5, 6 can be made heatable.

Figur 4 entspricht im wesentlichen Figur 3 , wobei in dem vorliegenden Fall noch die Schläuche 11 dargestellt sind, mit denen die Verschiebung der Verstellmittel 9, 10 quer zur Transportrichtung der Folienbahn bewirkt wird. FIG. 4 corresponds essentially FIG. 3 , wherein in the present case, the tubes 11 are still shown, with which the displacement of the adjusting means 9, 10 is effected transversely to the transport direction of the film web.

Figur 5 zeigt ein zweireihiges Format mit jeweils vier Gegenlagem 7 zur Herstellung der erfindungsgemäßen Verbindungselemente an Verpackungen, die in einem ontsprechenden Format angeordnet sind. Diese Gegenlager 7 weisen jeweils eine Nut 13 auf, die mit dem Prägemittel (nicht dargestellt) zusammenwirkt, um das Orfindungsgemäße Verbindungselement in die Seitenwand der Verpackungsmulde und In den Deckel einzuprägen. Des weiteren weist das erfindungsgemäße Gegenlager vier Ausnehmungen 14 auf, an denen die Nut unterbrochen ist und die bis zu dem oberen Rand des Gegenlagers 7 reichen. Zwei geheizte Prägemittel (nicht dargestellt) werden quer zu der mit dem Pfeil dargestellten Transportrichtung nach außen gedrückt und prägen dadurch die formschlüssige Verbindung in dem Deckel bzw. die Seitenwand der Verpackungsmulde. Sodann werden die Prägemittel wiederzunickgezogen und zeitgleich oder kurz danach die Gegenmittel mittels eines Antriebs im oder gegen den Uhrzeigersinn um 45° gedreht, bis die Ausnehmungen 14 deckungsgleich mit den formschlüssigen Verbindungen in den Verpackungen sind. Danach können die Gegenlager 7 abgesenkt werden, ohne die formschlüssige Verbindung zu beschädigen und die mit der formschlüssigen Verbindung versehenen Verpackungsmulden können um einen Takt weitertransportiert werden. Zwischen zwei Takten werden die Gegenlager wieder um 45° in ihre ursprüngliche Lage zurückgedreht und können, sobald der Weitertransport der Verpackungsmulden beendet ist, mit einem weiteren Format von Verpackungen in Eingriff gebracht werden, um formschlüssige Verbindungen in die Verpackung einzufügen. FIG. 5 shows a double-row format, each with four counter-bearings 7 for producing the connecting elements according to the invention to packaging, which are arranged in an ontsprechenden format. These abutment 7 each have a groove 13 which cooperates with the embossing means (not shown) to impress the Orfindungsgemäße connecting element in the side wall of the packaging tray and in the lid. Furthermore, the counter bearing according to the invention has four recesses 14, on which the groove is interrupted and which extend to the upper edge of the counter bearing 7. Two heated embossing means (not shown) are pressed transversely to the direction of transport shown with the arrow to the outside and thereby shape the positive connection in the lid or the side wall of the packaging tray. Then the embossing agents wiederzunickgezogen and at the same time or shortly thereafter, the antidote by means of a drive in the counterclockwise direction or rotated by 45 ° until the recesses 14 are congruent with the positive connections in the packaging. Thereafter, the abutment 7 can be lowered without damaging the positive connection and provided with the positive connection packaging troughs can be transported by one clock. Between two cycles, the counter bearings are rotated back 45 ° to their original position and, once the further transport of the packaging trays is completed, can be brought into engagement with another format of packaging to insert positive connections in the package.

In Figur 6 ist ein Schnitt durch eine Reihe von Gegenlagem 7 sowie eine Vergrößerung B dargestellt. Deutlich ist zu erkennen, dass die Gegenlager 7 um eine vertikale Achse 15 drehbar sind. Die Verdrehung erfolgt im vorliegenden Fall jeweils um 45° im und gegen den Uhrzeigersinn mittels eines Zahnriemens 17, der jeweils mit einem Zahnrad 16 in Eingriff steht. Der Fachmann versteht, dass auch jeder andere Antrieb in Frage kommt. Der Fachmann versteht, daß die Einformung der Verbindungen nicht quer zur Transportrichtung erfolgen muß, sondern auch an jeder anderen Stelle angeordnet sein kann.In FIG. 6 is a section through a series of counter-7 and a magnification B shown. It can be clearly seen that the counter-bearings 7 are rotatable about a vertical axis 15. The rotation takes place in the present case in each case by 45 ° clockwise and counterclockwise by means of a toothed belt 17, which is in each case with a gear 16 in engagement. The skilled person understands that every other drive comes into question. The skilled person understands that the formation of the compounds does not have to be transverse to the transport direction, but can also be arranged at any other location.

Der Antrieb des Zahnriemens 17 ist in Figur 7 dargestellt. Dieser erfolgt in dem vorliegenden Fall durch einen Pneumatikzylinder 18, der einen Hebel 19 im und gegen den Uhrzeigersinn abwechselnd antreibt. Dieser Antrieb wird durch den Zahnriemen 17 auf alle zehn Zahnräder 16 übertragen und treibt diese synchron an. Der Fachmann versteht, dass auch jeder andere Antrieb in Frage kommt.The drive of the toothed belt 17 is in FIG. 7 shown. This takes place in the present case by a pneumatic cylinder 18 which alternately drives a lever 19 clockwise and counterclockwise. This drive is transmitted through the toothed belt 17 to all ten gears 16 and drives them synchronously. The skilled person understands that every other drive comes into question.
