Description
Die Erfindung betrifft eine Vorrichtung zum Formen von tiefgezogenen Behältern nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for forming thermoformed containers according to the preamble of claim 1.
Eine derartige Vorrichtung ist aus der US 4,562,717 bekannt. Bei der bekannten Vorrichtung wird zum Vermeiden von Unregelmäßigkeiten in der Becherwand, insbesondere von Falten, ein aus einem elastischen Material bestehender Stempelkörper verwendet. Der Stempelkörper, der mit einer konisch ausgebildeten Matrize, die die Außenform des Bechers bestimmt zusammenwirkt, weist hierbei eine Schräge zwischen 0 Grad und 20 Grad auf. Ferner weist der Stempelkörper eine zentrisch angeordnete Ausnehmung auf, deren Form kegelstumpfförmig ist, wobei in der Ausnehmung zusätzlich ein zylindrisch geformter Aufnahmestift angeordnet ist. Beim Tiefziehen des Behälters ist in der Endstellung des Stempelkörpers, bei der der Stempelkörper vollständig in der Matrize eingetaucht ist, der Freiraum zwischen dem zylindrisch geformten Stift und dem Stempelkörper durch eine Verformung des Stempelkörpers vollständig ausgefüllt. Weiterhin liegt der Stempelkörper an seinem Außenumfang vollständig an der Materialbahn im Bereich der Matrize an.Such a device is known from US 4,562,717 known. In the known device to avoid irregularities in the cup wall, in particular of folds, an existing of an elastic material punch body is used. The punch body, which cooperates with a conically shaped die, which determines the outer shape of the cup, in this case has a slope between 0 degrees and 20 degrees. Further, the punch body has a centrally arranged recess whose shape is frustoconical, wherein in the recess additionally a cylindrically shaped receiving pin is arranged. During deep drawing of the container is in the end position of the punch body, in which the punch body is completely immersed in the die, the space between the cylindrically shaped pin and the punch body completely filled by a deformation of the punch body. Furthermore, the punch body lies on its outer circumference completely against the material web in the region of the die.
Es hat sich herausgestellt, dass mit einer derart ausgebildeten Vorrichtung sich zwar die angesprochenen Unregelmäßigkeiten bzw. Falten in der Wand des Behälters vermeiden lassen, dass jedoch die Stapelfähigkeit der Behälter relativ schlecht ist. Hierbei wird unter einer guten Stapelfähigkeit der Behälter die Eigenschaft verstanden, dass ineinander eingesetzte Behälter an deren umlaufendem Behälterrand möglichst vollständig anliegen, so dass sich bei einer bestimmten Stapelhöhe möglichst viele Behälter ineinander stapeln lassen und der Stapel gleichzeitig eine möglichst vertikale Ausrichtung aufweist. Ist dies nicht der Fall, wird sowohl bei der Verarbeitung der Behälter in einer Verpackungsmaschine, die die Behälter füllt und verschließt, als auch bei der Handhabung der Behälter, insbesondere beim Austrennen einzelner Behälter aus einem Behälterstapel in einem Bevorratungsmagazin ein erhöhter Aufwand erforderlich.It has been found that with such a device, although the mentioned irregularities or wrinkles in the wall of the container can be avoided, however, that the stackability of the container is relatively poor. Here, a good stackability of the container is understood the property that nestled containers as completely as possible rest against the peripheral edge of the container, so that at a certain stack height as many containers stack each other and the stack has the same vertical orientation as possible. If this is not the case, both in the processing of the container in a packaging machine, which fills the containers and closes, as well as in the handling of the container, especially when removing individual containers from a container stack in a storage magazine, an increased effort required.
Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Formen von tiefgezogenen Behältern nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass deren Stapelfähigkeit verbessert wird. Diese Aufgabe wird bei einer Vorrichtung zum Formen von tiefgezogenen Behältern mit den Merkmalen des Anspruchs 1 gelöst.Based on the illustrated prior art, the invention has the object, a device for forming deep-drawn containers according to the preamble of claim 1 such that their stackability is improved.

Es hat sich nämlich herausgestellt, dass dadurch beim Herausfahren des Stempelkörpers aus der Matrize bzw. beim Entformen der Behälter diese im Bereich der Öffnung des Behälters, welcher den Bereich des Becherrandes bildet, eine sehr hohe, gleichbleibende Genauigkeit bzw. Konizität aufweisen. Dadurch wird die Stapelfähigkeit der Behälter deutlich erhöht bzw. verbessert.The invention is based on the idea that in the end position of the plunger body, in which this is in its lowest position in the die, between the plunger body and the container wall in the region of the opening portion of the container, a free space is formed.

Vulkanisierte Stempelkörper 10 können durch Schwefel- oder Peroxyd-Behandlung vulkanisiert sein. Die Trägerplatte 18 kann aus z.B. nitriertem oder einsatzgehärtetem oder einsatzgehärtetem nitriertem Stahl sein. Hierbei weist die aus Metall bestehende Trägerplatte 18 in etwa einen Außendurchmesser auf, der dem Außendurchmesser des Stempelkörpers 10 entspricht.The stamp body 10 described so far can be vulcanized onto a carrier element or a carrier plate 18. This can be done by a solvent-based two-component or one-component system or by means of a water-soluble binding system. Vulcanized stamper bodies 10 may be vulcanized by sulfur or peroxide treatment. The support plate 18 may be made of e.g. nitrided or case hardened or case hardened nitrided steel. Here, the metal carrier plate 18 has approximately an outer diameter which corresponds to the outer diameter of the punch body 10.
In der Fig. 2 ist ein zweiter Stempelkörper 20 dargestellt. Der zweite Stempelkörper 20 unterscheidet sich von dem ersten Stempelkörper 10 im Wesentlichen durch die Verwendung eines in der Bohrung 21 angeordneten metallischen Einsatzkörpers 22. Der Einsatzkörper 22 weist einen zylindrischen Bereich 23 auf, der sich auf der der Trägerplatte 24 gegenüberliegenden Seite im Durchmesser erweitert. Die Oberseite 25 des Einsatzkörpers 22 kann hierbei als Prägeplatte ausgebildet sein, welche beispielhaft einen erhöhten, radial umlaufenden Prägerand 27 aufweist, der eine entsprechende Vertiefung im Bodenbereich eines Behälters 1 ausbildet (Fig. 3).In the Fig. 2 a second punch body 20 is shown. The second plunger body 20 differs from the first plunger body 10 essentially by the use of a metal insert body 22 arranged in the bore 21. The insert body 22 has a cylindrical region 23 which widens in diameter on the side opposite the support plate 24. The upper side 25 of the insert body 22 may in this case be formed as an embossing plate, which by way of example has an elevated, radially surrounding embossing edge 27, which forms a corresponding recess in the bottom region of a container 1 ( Fig. 3 ).
In der Längsachse des Einsatzkörpers 22 ist noch eine Aufnahmebohrung 28 ausgebildet, in der eine nicht dargestellte Schraube angeordnet werden kann, welche den Einsatzkörper 22 mit der Trägerplatte 24 verschraubt bzw. verspannt, und welche eine Belüftungsbohrung aufweisen kann. Die Befestigung des Stempelkörpers 20 mit der Trägerplatte 24 erfolgt über den mit der Trägerplatte 24 verschraubten Einsatzkörper 22, so dass auf eine Vulkanisierung des Stempelkörpers 20 verzichtet werden kann. Der Außendurchmesser bzw. die Form des Einsatzkörpers 22 ist derart, dass zwischen dem Außenumfang des Einsatzkörpers 22 und dem Innenumfang des zweiten Stempelkörpers 20 ein ringförmiger Freiraum 29 ausgebildet ist.In the longitudinal axis of the insert body 22, a receiving bore 28 is still formed, in which a screw, not shown, can be arranged, which screwed the insert body 22 with the support plate 24 or braced, and which may have a ventilation hole. The attachment of the punch body 20 with the support plate 24 via the screwed to the support plate 24 insert body 22, so that can be dispensed with a vulcanization of the punch body 20. The outer diameter or the shape of the insert body 22 is such that an annular clearance 29 is formed between the outer circumference of the insert body 22 and the inner circumference of the second punch body 20.

Die Länge l entspricht der Länge L weniger der doppelten Wanddicke t ± 5 mm. Die Breite B entspricht der inneren Breite des Behälters ± 3 mm. Weiterhin beträgt die Innenbreite b der Breite B weniger der doppelten Wanddicke t ± 5 mm. Der äußere Radius R beträgt zwischen 2 mm und 40 mm, während der innere Radius r etwa zwischen 0,5 mm und 30 mm beträgt. Die Höhe H entspricht der Höhe der Behälter. Auch hier kann der der Trägerplatte 31 abgewandte Bereich des Stempelkörpers 30 gegenüber dem der Trägerplatte 31 zugewandten Bereich entsprechend den beiden Stempelkörpern 10, 20 vergrößert ausgebildet sein (nicht dargestellt). Auch kann, entsprechend dem Stempelkörper 20, der Stempelkörper 30 auch unter Verwendung eines Einsatzes ausgebildet sein. Weiterhin kann die Außenform des Stempelkörpers 30 entweder zylindrisch sein, oder einen Konizitätswinkel α3 von 0 Grad bis zu etwa 8 Grad aufweisen.In the 4 and 5 a third punch body 30 is shown for forming approximately octagonal containers. Here, the length L of the inner length of the container corresponds to ± 3 mm. The length l corresponds to the length L less twice the wall thickness t ± 5 mm. The width B corresponds to the inner width of the container ± 3 mm. Furthermore, the inner width b of the width B is less than twice the wall thickness t ± 5 mm. The outer radius R is between 2 mm and 40 mm, while the inner radius r is approximately between 0.5 mm and 30 mm. The height H corresponds to the height of the containers. Here, too, the region of the plunger body 30 facing away from the carrier plate 31 can be enlarged relative to the region facing the carrier plate 31 corresponding to the two punch bodies 10, 20 (not shown). Also, according to the punch body 20, the punch body 30 may be formed using an insert. Further, the outer shape of the punch body 30 may be either cylindrical, or have a taper angle α3 of 0 degrees to about 8 degrees.

An allen vorstehend genannten Behältern kann ein Rollrand 5 vorgesehen werden mit einem Durchmesser von etwa 1 bis 2,5 mm. Die Behälter können einen Siegelflansch aufweisen. Der Siegelflansch, der nachfolgend auch als Rollrand 5 bezeichnet wird, ist zweckmässig ein endloser Siegelflansch, und kann beispielsweise 2,5 bis 5,0 mm breit sein. Der Seitenwandwinkel kann zwischen 1 und 20° betragen.In all the above-mentioned containers, a rolling edge 5 can be provided with a diameter of about 1 to 2.5 mm. The containers may have a sealing flange. The sealing flange, the hereinafter also referred to as a rolled edge 5 is suitably an endless sealing flange, and may for example be 2.5 to 5.0 mm wide. The side wall angle can be between 1 and 20 °.
Das Verfahren mit vorliegender Vorrichtung lässt eine Produktionsgeschwindigkeit von beispielsweise 50 bis 150 und insbesondere von 70 bis 130 Takten/min zu. Es hat sich dabei als vorteilhaft erwiesen, wenn die Materialbahn 2 bei der Verarbeitung in der Vorrichtung 40 mit einer Schicht aus geeignetem Schmierstoff, bzw. Öl oder Fett, versehen ist. Hierbei haben sich Schichtmengen von 300 bis 800mg/m2, insbesondere von 400 bis 600mg/m2 als vorteilhaft erwiesen.The method with the present device allows for a production rate of, for example, 50 to 150 and in particular from 70 to 130 cycles / min. It has proved to be advantageous if the material web 2 is provided during processing in the device 40 with a layer of suitable lubricant, or oil or grease. In this case, layer quantities of 300 to 800 mg / m 2 , in particular from 400 to 600 mg / m 2 have proved to be advantageous.
Die Vorrichtung 40 weist eine die Außenform des Behälters 1 bestimmende Matrize 41 aufweist, die beispielhaft mit dem Stempelkörper 10 zusammenwirkt. Hierbei weist die Innenwand 42 der Matrize 41 einen Konizitätswinkel α4 von 1 Grad bis 20 Grad, insbesondere von 5 Grad bis 12 Grad auf, welcher das Entformen aus der Matrize 41 und ein Ineinanderstapeln von Behältern 1 ermöglicht bzw. verbessert. Weiterhin weist der Stempelkörper 10 auf der der Matrize 41 zugewandten Seite eine etwas geringere Größe auf als die Matrize 41 im Bereich ihres Öffnungsquerschnitts 45.The device 40 has a die 41 which determines the outer shape of the container 1 and interacts with the stamp body 10 by way of example. Here, the inner wall 42 of the die 41 has a Konizitätswinkel α4 of 1 degree to 20 degrees, in particular from 5 degrees to 12 degrees, which allows the removal from the die 41 and a nesting of containers 1 or improved. Furthermore, the stamp body 10 has a slightly smaller size on the side facing the die 41 than the die 41 in the region of its opening cross section 45.
Beispielhaft wird zum Tiefziehen der Behälter 1 die Matrize 41 der Vorrichtung 40 in Richtung des Pfeils 43 nach unten gegen den starr angeordneten, und mit der Matrize 41 in dessen Längsachse ausgerichteten Stempelkörper 10 bewegt, wobei die Materialbahn 2 mittels nicht dargestellter Klemmmittel in bekannter Art und Weise eingespannt wird. Hierbei wird beim Eintauchen des Stempelkörpers 10 in die Matrize 41 der Stempelkörper 10 sowohl axial als auch radial komprimiert, wobei zwischen dem Bereich 13 des Stempelkörpers 10 und der Innenwand 42 die Materialbahn 2 gezogen wird, ohne dass es einen Freiraum zwischen dem Bereich 13 des Stempelkörpers 10 und der Innenwand 42 sowie zwischen der Innenwand 42 und der Matrize 41 gibt. Dadurch wird die Seitenwand 4 des Behälters 1 ausbildet.By way of example, for deep drawing of the container 1, the die 41 of the device 40 in the direction of arrow 43 down against the rigidly arranged, and aligned with the die 41 in the longitudinal axis aligned punch body 10, wherein the web 2 by means not shown clamping means in a known manner and Way is clamped. Here, when the plunger body 10 is dipped into the die 41, the plunger body 10 is compressed both axially and radially, whereby the material web 2 is drawn between the area 13 of the plunger body 10 and the inner wall 42, without leaving any clearance between the area 13 of the plunger body 10 and the inner wall 42 and between the inner wall 42 and the die 41 are. As a result, the side wall 4 of the container 1 is formed.
Wie man insbesondere anhand der Fig. 8 erkennt, bei der der Stempelkörper 10 seine Endposition in Bezug auf die Matrize 41 hat, ist zwischen der Seitenwand 4 und dem Bereich 14 des Stempelkörpers 10 ein Abstand bzw. Freiraum 44 ausgebildet. Dieser Freiraum 44 besteht hierbei insbesondere im Bereich des späteren Becherrandes 5.How to particular on the basis of Fig. 8 recognizes, in which the punch body 10 has its end position with respect to the die 41 is between the side wall 4 and the region 14 of the punch body 10th a distance or clearance 44 is formed. This clearance 44 in this case consists in particular in the area of the later cup rim 5.
Am Ende des Tiefziehvorgangs wird der Materialbahnzuschnitt des Behälters 1 im Bereich seines Behälterrandes geformt, so dass sich der Rollrand 5 ausbildet (Fig. 9).At the end of the deep-drawing process, the material web blank of the container 1 is formed in the region of its container edge, so that the rolled edge 5 is formed ( Fig. 9 ).
Wie man am Besten anhand der Fig. 9 erkennt ist dabei wesentlich, dass durch die spezielle Ausbildung des Stempelkörpers 10 die Seitenwände 4 der Behälter 1 mit einer sehr hohen geometrischen Genauigkeit bzw. Reproduzierbarkeit hergestellt werden können. Dadurch lässt sich eine gute Stapelbarkeit der Behälter 1 ermöglichen, d.h., dass bei mehreren ineinander gestapelten Behältern 1 diese symmetrisch zu einer Längsachse 46 angeordnet sind, wobei die Rollränder 5 der Behälter 1 über ihren gesamten Umfang gesehen aufliegen.How best to use the Fig. 9 it is essential that the side walls 4 of the container 1 can be produced with a very high geometric accuracy or reproducibility by the special design of the stamp body 10. This makes it possible to achieve a good stackability of the containers 1, ie that, in the case of several containers 1 stacked one inside the other, they are arranged symmetrically to a longitudinal axis 46, the rolling edges 5 of the containers 1 resting over their entire circumference.
