Wird
in einer einer Siegelstation nachgeordneten Qualitätskontrolle
ein fehlerhaftes Arbeiten eines Siegelfaches festgestellt, ist es
erforderlich, die Schalensiegelmaschine unverzüglich abzuschalten, und
das fehlerhafte Bauteil, beispielsweise eine beschädigte
Schneide eines die Folienbahn schneidenden Messers, auszutauschen.
Vom Abschalten der Schalensiegelmaschine sind jedoch nachteilig
auch die noch funktionsfähigen Siegelfächer betroffen.
Um die damit einhergehenden Produktionsausfälle zu minimieren,
wurde bereits in der Übersetzungsschrift
Der Erfindung liegt daher die Aufgabe zugrunde, einen Werkzeugsatz zum Versiegeln von Verpackungsbehältern aufzuzeigen, mit dem Produktionsausfälle nachhaltig verringert sind.Of the Invention is therefore the object of a tool set for Seal packaging containers show with the Production losses are sustainably reduced.
Diese Aufgabe ist erfindungsgemäß durch einen Werkzeugsatz mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den auf den Patentanspruch 1 rückbezogenen Unteransprüchen angegeben.These Task is according to the invention by a tool set solved with the features of claim 1. advantageous Further developments of the invention are in the on the claim 1 returned dependent claims specified.
Der erfindungsgemäße Werkzeugsatz zeichnet sich dadurch aus, dass jeder Arbeitskolben wenigstens ein in seinem Hubweg stellbeweglich geführtes Sperrglied aufweist. Mit seiner Stellbeweglichkeit kann das Sperrglied zwischen wenigstens einer Arbeitsstellung, in welcher der Arbeitskolben seine ihm zugedachte Arbeitsbewegung verrichten kann, und wenigstens einer Sperrstellung, in welcher der Arbeitskolben an der Ausführung seiner Arbeitsbewegung gehindert ist, wahlweise hin- und hergestellt werden. Im Volllastbetrieb des erfindungsgemäßen Werkzeugsatzes befinden sich die Sperrglieder sämtlicher Arbeitskolben in ihrer Arbeitsstellung. Im Teillastbetrieb befindet sich das Sperrglied wenigstens eines der Arbeitskolben in seiner Sperrstellung. Mit den stellbeweglich geführten Sperrgliedern ist somit vorteilhaft erreicht, dass bei einer vorzugsweise pneumatischen Ansteuerung der Arbeitskolben über die gemeinsame Steuerleitung lediglich diejenigen Arbeitskolben eine Arbeitsbewegung ausführen können, deren Sperrglieder sich in der Arbeitsstellung befinden. Im Falle eines fehlerhaften Arbeitens eines einzelnen Siegelfaches kann damit zunächst einmal nur der Arbeitskolben des fehlerhaften Siegelfaches verriegelt werden. Nachfolgend kann die Bestückung des fehlerhaften Siegelfaches mit Verpackungsbehältern über die Steuerung einer der Versiegelungsstation vorgeordneten Sammelstation ausgesetzt werden. Führungsflächen ausbildende Siegeleinsätze sind vorteilhaft unbeweglich ausgeführt, so dass ein Verunglücken von Verpackungsbehältern beim Hindurchführen durch fehlerhafte Siegelpakete zuverlässig verhindert ist. Der erfindungsgemäße Werkzeugsatz kann somit bis zu einem Schichtende oder einem geplanten Wartungsintervall im Teillastbetrieb weiter gefahren werden, so dass Produktionsausfälle nachhaltig verringert sind.Of the inventive tool set is characterized from that each piston at least one adjustable in its stroke having guided locking member. With his adjustable mobility the locking member between at least one working position, in which of the working pistons can perform its intended working movement, and at least one blocking position, in which the working piston hindered in the execution of his labor movement, optionally back and forth. In full load operation of the invention Tool set are the locking members of all Working piston in its working position. In partial load operation is the locking member at least one of the working piston in his Blocking position. With the adjustable movable locking members is thus advantageously achieved that in a preferably pneumatic Control of the working piston via the common control line only those working pistons perform a working movement can, whose locking members are in the working position. In case of a faulty working of a single sealed compartment can thus initially only the working piston of the faulty Sealed fold locked. Subsequently, the equipment of the defective seal compartment with packaging containers the control of a collecting station upstream of the sealing station get abandoned. Guiding surfaces forming Sealing inserts are advantageously designed immovable, so that an accident of packaging containers when passing through faulty seal packages reliably is prevented. The tool set according to the invention can thus be up to the end of a shift or a planned maintenance interval be continued in partial load operation, so that production losses are sustainably reduced.
Nach einer ersten Weiterbildung der Erfindung ist jedes Sperrglied stellbeweglich in einer Drehführung gehalten, deren Drehachse konzentrisch zur Drehachse des dem Sperrglied jeweils zugeordneten Arbeitskolbens ausgebildet ist. Mit der Drehführung können die Stellbewegungen des Sperrgliedes besonders raumsparend und betriebssicher ausgeführt werden. Grundsätzlich liegt es jedoch im Rahmen der Erfindung, die Stellbewegung mittels Gerad- oder Kurvenführungen zu realisieren.To a first embodiment of the invention, each locking member is adjustable held in a rotary guide whose axis of rotation concentric to the axis of rotation of the locking member respectively associated working piston is trained. With the rotation guide, the Actuating movements of the locking member particularly space-saving and reliable be executed. Basically, it is in the context of the invention, the adjusting movement by means of straight or curved guides to realize.
Nach einer nächsten Weiterbildung der Erfindung weist jedes Sperrglied und der ihm jeweils zugeordnete Arbeitskolben kämmend miteinander in Eingriff bringbare Sperrzähne auf. Dabei erlaubt die kämmende Anordnung der Sperrzähne eine besonders gleichmäßige Kräfteverteilung der vom Sperrglied ausgehenden Sperrkräfte im Arbeitskolben. Die Anzahl der Sperrzähne ist mit Vorteil so gewählt, dass bauteilbeanspruchende Lastspitzen vermieden sind.According to a next development of the invention, each locking member and its associated each working piston meshingly engageable with each other locking teeth. The meshing arrangement of the ratchet teeth allows a particularly uniform distribution of forces from the barrier limb outgoing blocking forces in the working piston. The number of ratchet teeth is advantageously chosen so that component-stressing load peaks are avoided.
Nach einer besonders vorteilhaften Weiterbildung der Erfindung weisen die Sperrzähne jedes Sperrgliedes und die Sperrzähne jedes Arbeitskolbens quer zum Hubweg des jeweiligen Arbeitskolbens ausgerichtete Sperrflächen auf. Erlauben die Sperrflächen dem gesperrten Arbeitskolben eine eingeschränkte Arbeitsbewegung, fungieren die Sperrflächen als Anschlagsflächen. Dabei können die Sperrflächen sowohl einen rechtwinkligen, geneigten oder sogar konischen Verlauf zum Hubweg des Arbeitskolbens aufweisen.To a particularly advantageous embodiment of the invention the ratchet teeth of each locking member and the ratchet teeth each working piston transversely to the stroke of the respective working piston aligned blocking surfaces. Allow the restricted areas the locked piston a limited working movement, the blocking surfaces act as stop surfaces. The blocking surfaces can be both a right-angled, inclined or even conical course to the stroke of the working piston exhibit.
Nach einer weiteren besonders vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Sperrzähne jedes Sperrgliedes und die Sperrzähne jedes Arbeitskolbens längs zum Hubweg des jeweiligen Arbeitskolbens ausgerichtete Gleitflächen aufweisen, mit denen die Drehführung des jeweiligen Sperrgliedes ausgebildet ist. Die Drehführung gewährleistet dabei den passgenauen Eingriff der einander kämmenden Sperrzähne von Sperrglied und Arbeitskolben. Die Gleitflächen sind vorzugsweise jeweils inmitten einer an einem Sperrzahn ausgebildeten Sperrfläche angeordnet, so dass jeder Sperrzahn einen Absatz erhält, dessen Höhe der Breite der Gleitfläche entspricht. Um eine sichere und besonders einfache Übertragung der Kolbenbewegungen auf die anderen Funktionsteile der den Arbeitskolben jeweils zugeordneten Siegelpakete zu gewährleisten, ist jedes Sperrglied als Sperrring ausgebildet, durch welchen die Kolbenstange des ihm jeweils zugeordneten Arbeitskolbens hindurchgeführt ist. Die Rückstellbewegungen der Arbeits kolben veranlassende Kolbendruckfedern sind mit Vorteil ebenfalls durch die als Sperrringe ausgebildeten Sperrglieder hindurchgeführt. Die am Sperrglied ausgebildeten Sperrzähne weisen mit Vorteil eine Teilung auf, die der Teilung der am Arbeitskolben angeordneten Sperrzähne entspricht.To a further particularly advantageous embodiment of the invention is provided that the ratchet teeth of each locking member and the ratchet teeth of each working piston along aligned to the stroke of the respective working piston sliding surfaces have, with which the rotary guide of the respective locking member is trained. The rotation guide ensures while the precise engagement of the meshing ratchet teeth of locking member and working piston. The sliding surfaces are preferably in each case in the middle of a trained on a ratchet tooth Locking surface arranged so that each ratchet has a paragraph receives, the amount of the width of the sliding surface equivalent. For a safe and very easy transmission the piston movements on the other functional parts of the working piston respectively Associated seal packages is to ensure each locking member designed as a locking ring, through which the piston rod of him each associated working piston is passed. The return movements of the working piston inducing piston compression springs are also advantageous by trained as locking rings Passed locking members. The locking teeth formed on the locking member Advantageously have a pitch, the division of the working piston arranged ratchet teeth corresponds.
Nach einer anderen Weiterbildung der Erfindung ist jeder Drehführung ein Stellorgan zugeordnet, das mit dem Sperrglied des der Drehführung jeweils zugeordneten Arbeitskolbens über eine Evolventenverzahnung in Eingriff steht. Vorzugsweise weist das Stellorgan ein Ritzel auf, das mit einem am Sperrglied angeordneten Zahnkranzabschnitt in Eingriff steht. Die Drehachse des Ritzels und die Drehachse der Drehführung sind rechtwinklig zueinander angeordnet, so dass die Evolventenverzahnung dann als Kegelradverzahnung ausgebildet ist.To Another development of the invention is any rotary guide an actuator associated with the locking member of the rotary guide respectively associated working piston via an involute toothing engaged. Preferably, the actuator has a pinion on, with a arranged on the locking ring sprocket section engaged. The axis of rotation of the pinion and the axis of rotation of Rotary guide are arranged at right angles to each other, so that the involute toothing then formed as bevel gear teeth is.
Um ein unbeabsichtigtes Verstellen des Sperrgliedes zu verhindern, ist jedes Stellorgan über eine federbelastete Verriegelungsmechanik verdrehsicher im Oberwerkzeug gehalten. Mit der Verriegelungsmechanik ist insbesondere verhindert, dass während des Betriebes einer Schalensiegelmaschine auftretende Vibrationen und Stöße zu einem unbeabsichtigten Verdrehen des Stellorganes führen. Vorzugsweise ist das Stellorgan bzw. die daran angeordnete Verriegelungsmechanik von Hand bzw. manuell betätigbar ausgebildet.Around to prevent unintentional adjustment of the locking member is each actuator via a spring-loaded locking mechanism held against rotation in the upper tool. With the locking mechanism in particular, prevents during operation a tray sealing machine occurring vibrations and shocks lead to unintentional rotation of the actuator. Preferably, the actuator or the locking mechanism arranged thereon designed by hand or manually operated.
Eigenständiger Schutz wird für ein Oberwerkzeug begehrt, das für den erfindungsgemäßen Werkzeugsatz zum Versiegeln von Verpackungsbehältern geeignet ist. Das erfindungsgemäße Oberwerkzeug ist insbesondere ein bekanntes mit Sperrgliedern nachgerüstetes Oberwerkzeug oder es ist als Austauschteil für einen bekannten Werkzeugsatz geeignet.standalone Protection is sought for a top tool that is for the tool set according to the invention for sealing of packaging containers is suitable. The invention Upper tool is in particular a known retrofitted with locking members Upper tool or it is as a replacement part for a known Tool set suitable.
