Description

Die Erfindung betrifft eine Vorrichtung zum Einschieben von Produkten in ein Verpackungsbehältnis in einer Verpackungsmaschine, mit einem über eine gewisse Strecke parallel zu den Produkten geführten Einschubstößel und einer Abdeckzunge, die mittels einer 1. Bewegungssteuerung oberhalb der Produkte vorpositionierbar und mittels einer 2. Bewegungssteuerung auf die Produkte absenkbar ist, wobei der Einschubstößel und die Abdeckzunge zusammen eine die Produkte in das Behältnis einführende Einschubbewegung ausführen.The invention relates to a device for inserting Products in a packaging container in a packaging machine, with one over a certain distance parallel to slide-in ram guided by the products and a cover tongue, which by means of a 1st movement control above the Products can be pre-positioned and by means of a second movement control can be lowered onto the products using the slide-in ram and the cover tongue together a the products Carry out insertion movement into the container.

Vorrichtungen des genannten Aufbaus finden im allgemeinen bei kontinuierlich arbeitenden Verpackungsmaschinen Verwendung, die beispielsweise mit einer Produktkette ausgerüstet sind, auf der die zu verpackenden Produkte wie Tuben, Flaschen oder auch Stapel von Blisterpackungsstreifen befördert werden. Parallel zur Produktkette werden Behältnisse, wie Faltschachteln, geführt, in die die Produkte gegebenenfalls zusammen mit einem Prospekt einzuschieben sind. Dies geschieht mit Hilfe von Einschubstößeln, die in Hauptförderrichtung mittels eines Kettenförderers ebenfalls parallel zur Produktkette bewegt werden und zum Einschieben eine Einschubbewegung senkrecht zu ihrer Hauptförderrichtung ausführen.Devices of the stated structure are generally found use in continuously operating packaging machines, for example equipped with a product chain on which the products to be packaged such as tubes, bottles or also transported stacks of blister pack strips become. In parallel to the product chain, containers, such as folding boxes, into which the products may be must be inserted together with a prospectus. This happens with the help of slide-in plungers in the main conveying direction also parallel by means of a chain conveyor be moved to the product chain and to insert one Insertion movement perpendicular to their main conveying direction To run.

Insbesondere beim Einschieben eines Stapels von Blisterpackungsstreifen ist es notwendig, den Stapel von dem Einschieben in geringem Maße zusammenzudrücken und dadurch zu stabilisieren. Zu diesem Zweck ist es aus der DE 43 06 170 C1 bekannt, eine Abdeckzunge vorzusehen, die in einer angehobenen Ausrichtung über den Stapel von Packungsstreifen verfahren und dann auf diesen abgelegt wird. Die Abdeckzunge führt dann zusammen mit dem Einschubstößel eine aufeinander abgestimmte Einschubbewegung aus, wobei die Abdeckzunge so lange in Anlage mit dem Stapel von Packungsstreifen bleibt, bis dieser in dem Verpackungsbehältnis aufgenommen ist.Especially when inserting a stack of blister pack strips it is necessary to insert the stack from the to compress to a small extent and thereby to stabilize. For this purpose it is from DE 43 06 170 C1 known to provide a cover tongue, which in a raised alignment over the stack of packing strips proceed and then placed on it. The cover tongue then leads one together with the slide-in ram coordinated insertion movement, the cover tongue so long in plant with the stack of packing strips remains until it is in the packaging container is recorded.

Dabei ist es wesentlich, daß der Bewegungsablauf der Abdeckzunge exakt auf die Größe der einzuschiebenden Produkte abgestimmt ist. Wenn die Abdeckzunge zu früh auf dem Stapel von Packungsstreifen abgelegt wird und auf dessen Oberseite unter Druck verschoben wird, ohne daß der Stapel seitlich abgestützt ist, kann es passieren, daß der obere Packungsstreifen verschoben wird, wodurch die gewünschte Stapelform nicht mehr gegeben ist und der Stapel nicht mehr in das Behältnis eingeschoben werden kann. Die Höhenlage der Abdeckzunge bzw. deren Absenk- und Anhebbewegung wird über eine in einem verstellbaren Rahmenteil ausgebildete Kurvenbahn gesteuert, in der eine um eine horizontale Achse drehbare, die Höhenlage der Abdeckzunge bestimmende Kurvenrolle umläuft. Bei Erreichen eines vertikal tieferliegenden Abschnitts der Kurvenbahn wird die Kurvenrolle und somit auch die Abdeckzunge abgesenkt. In einem vertikal ansteigenden Abschnitt der Kurvenbahn wird die Abdeckzunge dementsprechend über die Kurvenrolle angehoben. It is essential that the movement of the cover tongue exactly to the size of the products to be inserted is coordinated. If the tongue is on the pile too soon is put down by packing strips and on its top is pushed under pressure without the stack laterally is supported, it can happen that the upper packing strip is moved, creating the desired stack shape no longer exists and the stack is no longer in the container can be inserted. The height of the cover tongue or their lowering and lifting movement is via a curved track formed in an adjustable frame part controlled, in which a rotatable around a horizontal axis, the cam roller determining the height of the cover tongue rotates. When reaching a vertically lower section the cam track becomes the cam roller and thus also the cover tongue lowered. In a vertically rising Section of the cam track becomes the cover tongue accordingly raised above the cam roller.

Bei einem Wechsel der zu verpackenden Produkte muß das Rahmenteil, in dem die Steuerkurve ausgebildet ist, in seiner Gesamtheit vertikal angehoben oder abgesenkt werden. Dieses vorgehen ist sehr mühsam und zeitaufwendig und somit kostenintensiv.When changing the products to be packaged, the frame part, in which the control curve is formed, in its The whole can be raised or lowered vertically. This proceeding is very tedious and time-consuming and therefore costly.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, die eine präzise Ablage der Abdeckzunge sicherstellt und eine einfache Umstellung auf unterschiedliche Produktformate ermöglicht.The invention has for its object a device of the type mentioned to create a precise filing of the Cover tongue ensures and a simple switch to allows different product formats.

Diese Aufgabe wird erfindungsgemäß bei einer Vorrichtung zum Einschieben von Produkten in ein Verpackungsbehältnis dadurch gelöst, daß die 2. Bewegungssteuerung eine im wesentlichen vertikale Steuerfläche und ein die Steuerfläche abgreifendes und dabei horizontal verstellbares Element aufweist, wobei die horizontale Verstellbewegung des Elementes über eine Umsetzvorrichtung in die vertikale Absenkbewegung der Abdeckzunge umsetzbar ist.This object is achieved in a device for inserting products into a packaging container solved in that the 2nd movement control is essentially one vertical control surface and a control surface Tapping and horizontally adjustable element has, the horizontal adjustment movement of the element via a transfer device into the vertical lowering movement the cover tongue can be implemented.

Die Erfindung geht ebenfalls von der grundsätzlichen Überlegung aus, das Zustellen der Abdeckzunge zu den Produkten, d.h. die Positionierung oberhalb des Produktstapels einerseits und die Absenkbewegung der Abdeckzunge auf den Produktstapel andererseits durch unabhängige Bewegungssteuerungen durchzuführen. Da bei einer Formatänderung sich in der Regel nur die Höhe des Produktstapels ändert, während die zustellbewegung zumindest annähernd gleichbleibt, muß bei einem Formatwechsel lediglich in die zweite Bewegungssteuerung eingegriffen werden.The invention is also based on the fundamental consideration off, the covering tongue for the products, i.e. the positioning above the product stack on the one hand and the lowering movement of the cover tongue onto the product stack on the other hand through independent movement controls perform. Since a format change in usually just changes the height of the product stack while the delivery movement remains at least approximately the same in the case of a format change, only in the second motion control be intervened.

Durch die Trennung der Zustell- bzw. Vorpositionierungsbewegung der Abdeckzunge und deren Absenkbewegung können die beiden Bewegungen jeweils unabhängig voneinander optimal an die zu verpackenden Produkte und auch die baulichen Gegebenheiten innerhalb der Maschine angepaßt werden, wodurch eine hohe Funktionssicherheit der Maschine erreicht ist.By separating the infeed or prepositioning movement the cover tongue and its lowering movement can both movements optimally independently of each other the products to be packaged and also the structural conditions be adjusted within the machine, whereby a high level of functional reliability of the machine is achieved.

Die Absenk- und Anhebbewegung der Abdeckzunge wird erfindungsgemäß nicht durch einen sich vertikal ändernden Verlauf einer horizontalen Steuerfläche, sondern durch einen sich horizontal ändernden Verlauf einer vertikalen Steuerfläche erreicht. Durch die vertikale Steuerfläche wird das die Steuerfläche abgreifende Element, bei dem es sich um eine Kurvenrolle handeln kann, die um eine vertikale Achse drehbar ist, horizontal verstellt. Diese horizontale Verstellbewegung der Kurvenrolle wird über die Umsetzvorrichtung insbesondere in Form eines einfachen Getriebes in eine vertikale Absenk- und Anhebbewegung der Abdeckzunge umgesetzt. Diese Ausgestaltung hat den Vorteil, daß es bei einer Formatverstellung somit lediglich notwendig ist, die Steuerfläche in der Maschine horizontal entlang einer Führung zu verschieben, was sich für einen Benutzer wesentlich einfacher erreichen läßt als eine vertikale Anhebung eines gesamten Rahmenteils. Darüber hinaus kann die Steuerfläche auch durch seitliches Herausziehen aus der Maschine ausgebaut und ausgewechselt werden.The lowering and lifting movement of the cover tongue is according to the invention not by a vertically changing course a horizontal control surface, but by one horizontally changing course of a vertical control surface reached. The vertical control surface will element controlling the control surface, which is a cam roller can act on a vertical axis is rotatable, horizontally adjusted. This horizontal adjustment movement the cam roller is over the transfer device especially in the form of a simple gear in a vertical lowering and lifting movement of the cover tongue implemented. This configuration has the advantage that it is Format adjustment is therefore only necessary Control surface in the machine horizontally along a guide to postpone what is essential for a user easier to achieve than a vertical lifting of a entire frame part. In addition, the control surface also removed by pulling it sideways out of the machine and be replaced.

Eine besonders einfache konstruktive Ausgestaltung der Steuerfläche ist gegeben, wenn diese an einer zur Formatänderung verstellbaren Verstellplatte ausgebildet ist, deren Oberfläche bzw. Oberflächenstruktur mittels der Kurvenrolle abgegriffen wird. Bei einer Formatänderung muß somit lediglich die Verstellplatte verstellt werden.A particularly simple design of the Control surface is given if this is on a format change adjustable adjustment plate is formed, the Surface or surface structure using the cam roller is tapped. If you change the format, you only have to the adjustment plate can be adjusted.

Um eine sichere Anlage der Kurvenrolle an der Steuerfläche zu gewährleisten, sollte diese mittels einer Feder gegen die Steuerfläche vorgespannt sein. To ensure that the cam roller fits securely on the control surface to ensure this should be countered by a spring the control surface is biased.

Als besonders vorteilhaft hat es sich erwiesen, wenn die Umsetzvorrichtung eine schräge Linearführung aufweist, die insbesondere von einem gegenüber der Horizontalen sowie der Vertikalen geneigten Führungsstab gebildet sein kann.It has proven to be particularly advantageous if the Transfer device has an oblique linear guide, the in particular one from the horizontal as well as the Vertical inclined guide rod can be formed.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, daß die zweite Bewegungssteuerung ein Steuerteil aufweist, das zusammen mit der Abdeckzunge als Einheit vertikal verstellbar und relativ zu dieser horizontal verschiebbar ist, und daß an dem Steuerteil die die Steuerfläche abgreifende Kurvenrolle gelagert ist. Die im wesentlichen horizontale Zustellbewegung der Abdeckzunge in die Position oberhalb des Produktstapels kann somit durchgeführt werden, ohne daß das Steuerteil bewegt wird, da dieses relativ zu der Abdeckzunge horizontal verschieblich ist. Das Steuerteil steuert die vertikale Absenkbewegung der Abdeckzunge und greift zu diesem Zweck mittels der Kurvenrolle die Steuerfläche ab. Aufgrund der schrägen Linearführung kann das Steuerteil der horizontalen Formgebung der Steuerfläche bzw. der Verstellplatte folgen und erfährt dabei gleichzeitig eine vertikale Verstellung, wodurch sich die Ausgangsposition für die Absenkbewegung des Steuerteils und somit der Abdeckzunge verändern läßt. Über den Winkel des geneigten Führungsstabes läßt sich das Verhältnis zwischen der horizontalen und der vertikalen Verstellbewegung des Steuerteils vorgeben, wobei vorzugsweise ein Winkel von 45° vorgesehen ist, so daß die beiden Verstellbewegungsanteile gleich sind.In a preferred embodiment of the invention, that the second movement control has a control part, that can be adjusted vertically together with the cover tongue as a unit and can be moved horizontally relative to it, and that on the control part the tapping the control surface Cam roller is mounted. The essentially horizontal Infeed movement of the cover tongue into the position above of the product stack can thus be carried out without the control part is moved because it is relative to the cover tongue is horizontally displaceable. The control section controls the vertical lowering movement of the cover tongue and grips the control surface by means of the cam roller from. Due to the oblique linear guide, this can Control part of the horizontal shape of the control surface or follow the adjustment plate and learns at the same time a vertical adjustment, which changes the starting position for the lowering movement of the control part and thus the cover tongue can be changed. About the angle of the inclined The relationship between the horizontal and vertical adjustment of the Specify control section, preferably an angle of 45 ° is provided so that the two adjustment movements are the same.

Für die erste Bewegungssteuerung, die die Zustell- bzw. Vorpositionierungsbewegung der Abdeckzunge steuert, ist ein in Richtung der Produkte verschieblicher Voreinschubwagen vorgesehen, der über eine Steuerkurve bewegbar ist und eine vertikale Führungsstange trägt, an der die Abdeckzunge und das Steuerteil vertikal verstellbar gelagert sind.For the first motion control, which the delivery or Pre-positioning movement of the cover tongue is a Slide-in trolleys that can be moved in the direction of the products provided that is movable via a control cam and a vertical guide rod on which the cover tongue and the control section is vertically adjustable.

Die Abdeckzunge soll sich in genannter Weise von oben auf das Produkt bzw. den Stapel von Verpackungsstreifen auflegen und diesen mit einer geeigneten, in der Regel relativ geringen Druckkraft beaufschlagen. Diese Druckkraft kann entweder durch das Eigengewicht der Abdeckzunge hervorgerufen werden, gegebenenfalls kann jedoch auch vorgesehen sein, daß die Abdeckzunge in die auf den Produkten aufliegende Position mittels einer Feder vorgespannt ist.The cover tongue should be on from above place the product or the stack of packaging strips and this with a suitable, usually relative apply low pressure. This pressure force can either caused by the weight of the cover tongue can be provided, if necessary be that the cover tongue in the lying on the products Position is biased by a spring.

An dem Steuerteil 16 ist eine um eine vertikale Achse D drehbare Kurvenrolle 17 gelagert, die auf einer im wesentlichen vertikalen Steuerfläche 24a abrollt, die an einer vertikalen Verstellplatte 24 ausgebildet ist. Die Kurvenrolle 17 ist mittels der auf dem schrägen Führungsstab 23 angeordneten Zug-Feder 27 gegen die Steuerfläche 24a gespannt. Die Verstellplatte 24 ist entlang einer horizontalen Führungsstange 25, die an einem vertikalen Ständer 26 gehalten ist, verstellbar.On the guide rod 9 is a longitudinally or vertically displaceable Sled 8 arranged, the one in Arm 21 extending in the direction of the product transport chain 3 carries, at its front free end a flexible cover tongue 6 is arranged. By sliding the carriage 8 along the vertical guide rod 9, the arm 21 and with it the cover tongue 6 raised and lowered vertically become. A roller 7 is rotatably mounted on the carriage 8, which engages in a horizontal guide groove 15, the is formed in a control part 16 which is longitudinally displaceable sits on the oblique guide rod 23 and by means of a Tension spring 27 biased downward on this is. On the control part 16 is around a vertical axis D rotatable cam roller 17 mounted on a substantially vertical control surface 24a that rolls on a vertical adjustment plate 24 is formed. The cam roller 17 is by means of the on the oblique guide rod 23 arranged tension spring 27 tensioned against the control surface 24a. The adjustment plate 24 is along a horizontal Guide rod 25 attached to a vertical stand 26 is held, adjustable.

An dem horizontal Führungsstab 19 ist desweiteren ein axial verschieblicher Einschubwagen 12 vorgesehen, der ebenfalls eine Führungsrolle 12a aufweist, die mit einer nicht dargestellten Steuerkurve in Anlage steht. An dem Einschubwagen 12 ist ein sich bis zur Produkttransportkette 3 erstreckender Einschubstößel 13 gelagert. Der Einschubstößel 13 durchgreift nahe seinem freien Ende eine Führung in dem Lagerblock 20 und trägt an seinem vorderen, freien Ende ein Einschubstück 5, dessen Höhe im wesentlichen mit der Höhe der zu verpackenden Produkte 4 übereinstimmt.On the horizontal guide rod 19 is also an axial Slidable slide-in cart 12 is also provided has a guide roller 12a, which with a not shown Control curve is in plant. On the slide-in car 12 is an extending up to the product transport chain 3 Insert plunger 13 mounted. The plunger 13 passes through a guide in the bearing block near its free end 20 and registers at its front, free end Insert piece 5, the height of which essentially corresponds to the height of the products to be packaged 4 matches.

Im folgenden wird ein Einschubzyklus anhand der Figuren 1 und 2 erläutert. In der in Fig. 1 dargestellten, zurückgezogenen Stellung befinden sich der Arm 21 und die daran ausgebildete Abdeckzunge 6 in einer zurückgezogenen Position, in der die Rolle 7 innerhalb der Führungsnut 15 nahe dem den Produkten 4 abgewandten Ende angeordnet ist und die Kurvenrolle 17 auf der Außenseite der Verstellplatte 24, d.h. der Steuerkurve 24a anliegt, wobei die Abdeckzunge 6 oberhalb der Produkte 4 sowie zurückgezogen von diesen angeordnet ist. The following is a slide-in cycle based on FIGS. 1 and 2 explained. In the withdrawn shown in Fig. 1 Position are the arm 21 and those on it trained cover tongue 6 in a retracted position, in which the roller 7 within the guide groove 15 close the end facing away from the products 4 and the Cam roller 17 on the outside of the adjustment plate 24, i.e. of the control curve 24a, the cover tongue 6 arranged above the products 4 and withdrawn from them is.

Bei Durchlaufen der Verpackungsmaschine wird zunächst der Voreinschubwagen 11 entlang dem horizontalen Führungsstab 19 gemäß den Figuren nach links, d.h. in Richtung der Produkttransportkette 3 verschoben, wodurch auch der Arm 21 mit der Abdeckzunge 6 nach links verschoben wird, wobei die Rolle 7 in der horizontalen Führungsnut 15 entlangrollt und den Arm 21 und die Abdeckzunge 6 dabei oberhalb der Produkte 4 hält. Der Voreinschubwagen 11 wird soweit verschoben, bis die Abdeckzunge 6 oberhalb der Produkte 4 angeordnet ist.When passing through the packaging machine, the Slide-in carriage 11 along the horizontal guide rod 19 according to the figures to the left, i.e. towards the product transport chain 3 shifted, whereby the arm 21st is moved to the left with the cover tongue 6, the Roll 7 rolls in the horizontal guide groove 15 and the arm 21 and the cover tongue 6 above the products 4 holds. The slide-in carriage 11 is moved so far until the cover tongue 6 is arranged above the products 4 is.

Bei dem weiteren Durchlaufen der Verpackungsmaschine gelangt die Kurvenrolle 17 in einen eine Vertiefung 24b aufweisenden Abschnitt der Steuerfläche 24a der Verstellplatte 24, wodurch das Steuerteil 16 aufgrund der Vorspannung der Feder 27 eine gemäß Fig. 1 nach rechts gerichtete Bewegung ausführen will. Der schräge Führungsstab 23 stellt jedoch eine lineare Zwangsführung für das Steuerteil 16 dar, so daß die nach rechts gerichtete, horizontale Bewegung gleichzeitig zu einer vertikal nach unten gerichteten Bewegung führt. Diese vertikale Absenkung des Steuerteils 16 führt zu einer entsprechenden Absenkung der Rolle 7, wodurch der Schlitten 8 entlang der vertikalen Führungsstange 9 nach unten bewegt wird. Dies führt dazu, daß der mit dem Schlitten 8 verbundene Arm 21 soweit abgesenkt wird, daß die Abdeckzunge 6 sich auf die Produkte 4 von oben auflegt und diese stabilisiert. Dieser Zustand ist in Fig. 2 dargestellt. Bei sehr empfindlichen Produkten kann auch vorgesehen sein, daß die Abdeckzunge 6 unmittelbar oberhalb der Produkte 4 gehalten wird, ohne auf diese eine Druckkraft auszuüben.When passing through the packaging machine the cam roller 17 into a recess 24b Section of the control surface 24a of the adjustment plate 24, whereby the control part 16 due to the bias of the Spring 27 a rightward movement according to FIG. 1 wants to execute. The oblique guide rod 23, however, provides a linear positive guidance for the control part 16, so that the rightward horizontal movement at the same time as a vertically downward movement leads. This vertical lowering of the control part 16 leads to a corresponding lowering of the roller 7, whereby the carriage 8 along the vertical guide rod 9 is moved down. This leads to the fact that with the Carriage 8 connected arm 21 is lowered so far that the cover tongue 6 is placed on the products 4 from above and stabilized it. This state is shown in Fig. 2. With very sensitive products can also be provided be that the cover tongue 6 immediately above the Products 4 is held without this compressive force exercise.

Bei weiterem Durchlaufen der Verpackungsmaschine wird nun über die nicht dargestellte Kurvenbahn die Führungsrolle 12a des Einschubwagens 12 verlagert, wodurch der Einschubwagen 12 entlang dem horizontalen Führungsstab 19 in Richtung der Produkttransportkette 3 und somit der Faltschachteltransportkette 1, d.h. gemäß den Figuren nach links bewegt wird. Gleichzeitig erfährt auch der Voreinschubwagen 11 eine entsprechende Bewegung, wodurch die Abdeckzunge 6 und das Einschubstück 5 in aufeinander abgestimmter Weise verschoben werden und die Produkte 4 unter Mitnahme des Prospekts 18 in die Faltschachtel 2 einführen. Anschließend werden der Voreinschubwagen 11 und der Einschubwagen 12 zurückgezogen und die Kurvenrolle 17 tritt aus der Vertiefung 24b der Steuerfläche 24a der Verstellplatte 24 heraus, so daß wieder die in Fig. 1 dargestellte Ausgangsposition erreicht ist.If the packaging machine continues to run, the guide roller over the cam track, not shown 12a of the slide-in carriage 12 is shifted, which causes the slide-in carriage 12 along the horizontal guide rod 19 in the direction the product transport chain 3 and thus the folding box transport chain 1, i.e. moved to the left according to the figures becomes. At the same time, the pre-insertion carriage also experiences 11 a corresponding movement, as a result of which the covering tongue 6 and the insert 5 in a coordinated manner be moved and the products 4 taking the Insert prospectus 18 into folding box 2. Subsequently the pre-insertion carriage 11 and the insertion carriage 12 are withdrawn and the cam roller 17 comes out of the recess 24b of the control surface 24a of the adjustment plate 24, see above that again the starting position shown in Fig. 1 is reached is.

Wie aus den vorstehenden Ausführungen ersichtlich ist, ergibt sich die Höhenlage der Abdeckzunge 6 in ihrer oberhalb der Produkte befindlichen Ausgangsstellung aus der Position der verstellplatte 24, während sich die vertikale Absenkbewegung der Abdeckzunge 6 aus der Tiefe der Vertiefung 24b der Verstellplatte 24 im Zusammenwirken mit der Kurvenrolle 18 sowie dem schrägen Führungsstab 23 ergibt. Eine Formatumstellung kann dadurch erreicht werden, daß die Verstellplatte 24 entlang der Führungsstange 25 horizontal verlagert wird. Dadurch wird die Höhenposition der Abdeckzunge 6 in ihrer Ausgangslage verstellt. Wenn die Verstellplatte 24 nicht ausgewechselt wird, bleibt das Maß der vertikalen Absenkung der Abdeckzunge 6 unverändert. Eine Darstellung nach erfolgter Formatumstellung durch Verlagern der Verstellplatte 24 ist in Figur 3 dargestellt, wobei zusätzlich das Einschubstück 5 durch ein anders dimensioniertes Einschubstück 5a ausgetauscht ist.As can be seen from the above, results the height of the cover tongue 6 in its above the starting position of the products from the position the adjustment plate 24 while the vertical lowering movement the cover tongue 6 from the depth of the recess 24b the adjustment plate 24 in cooperation with the cam roller 18 and the oblique guide rod 23 results. A format change can be achieved in that the adjustment plate 24 horizontally displaced along the guide rod 25 becomes. As a result, the height position of the covering tongue 6 adjusted in their starting position. If the adjustment plate 24 the degree of vertical reduction remains the cover tongue 6 unchanged. A depiction after the format has been changed by moving the adjustment plate 24 is shown in Figure 3, in addition the insert 5 by a differently dimensioned insert 5a is replaced.
