Abstract

The stamp (11) has a tool bar (12) with a lengthwise-running tool retaining groove (13), in which a separating cutter (14) and a seal strip (15) are held in mutually parallel arrangement. The separating cutter and the seal strip are held in the tool bar in longitudinal direction of the tool bar in tension-free and length-flexible manner. The separating cutter and/or the seal strip are exclusively and axially fixed at a longitudinal end in the tool bar, and are held at another longitudinal end in the tool bar by a tap slotted hole arrangement in an axially displaceable manner.

Description

Die Erfindung betrifft einen Trennschweißstempel für eine Trenn- und Siegelvorrichtung zum parallelen Trennen und Siegeln von aufeinanderliegenden Folienbahnen, insbesondere für Folienverpackungsmaschinen, mit einem Werkzeugbalken, der eine längsverlaufende Werkzeugaufnahmenut aufweist, in der eine Trennschneide und zumindest eine Siegelleiste in zueinander paralleler Anordnung gehalten sind. Derartige balkenförmige Trennschweißstempel werden im Betrieb auf die Schweißtemperatur der zu behandelnden Folienbahnen gebracht und auf eine Unterlage oder einen Auflagerbalken, über die die Folienbahnen geführt werden, abgesenkt. Hierbei entsteht durch die zumindest eine Siegelleiste eine Breitnaht und durch die parallel verlaufende Trennschneide eine Trennstelle, so daß die Folienbahnen gemeinsam quer getrennt werden und zumindest auf einer Seite der Trennstelle miteinander verbunden werden.The The invention relates to a separating welding punch for a separating and sealing device for parallel separation and sealing of superimposed film webs, especially for Film wrapping machines, with a tool bar, which is a longitudinal Tool holding groove, in which a cutting blade and at least a sealing strip are held in a parallel arrangement. Such bar-shaped Separating welding dies are in operation to the welding temperature of the treated Sheets brought and placed on a base or a support beam, over the led the film webs be lowered. This results from the at least one sealing strip a wide seam and through the parallel cutting edge a separation point, so that the Film webs are separated transversely and at least on one Side of the separation point are interconnected.

Ein Anwendungsgebiet derartiger Trennschweißstempel sind Folienverpackungsmaschinen, bei denen Packgutstücke zwischen zwei Folienbahnen eingeschlossen werden sollen. Hierbei wird zwischen einzelnen Packgutstücken, die im Durchlauf durch die Folienverpackungsmaschine aufeinanderfolgen, ein Trennen der Folienbahnen und beidseitig der Trennstelle ein gleichzeitiges doppeltes Schweißen oder Siegeln erforderlich, während an den seitlichen Rändern der Folienbahnen zu beiden Seiten der Packgutstücke jeweils nur ein einfaches Schweißen und gegebenenfalls ein Abtrennen von ungleichmäßigen Überständen erforderlich ist. Die vorgenannten Vorgänge, d. h. sowohl das Siegeln oder Schweißen als auch das Trennen erfolgen thermisch-mechanisch, jeweils unter unmittelbarem mechanischem Kontakt der Trennschneide und der Siegelleisten mit den Folienbahnen, wobei zum Trennen eine hö here Temperatur als zum Siegeln erforderlich ist.One Field of application of such separating welding dies are film packaging machines, in which packaged goods to be enclosed between two film webs. in this connection is between individual packaged goods that pass through following the film wrapping machine, separating the film wrapping machine Film webs and on both sides of the separation point a simultaneous double welding or seals required while at the side edges the film webs on both sides of Packgutstücke each only a simple welding and optionally a separation of uneven supernatants is required. The aforementioned operations, d. H. both the sealing or welding and the separation take place thermo-mechanical, each under direct mechanical contact the cutting edge and the sealing strip with the film webs, wherein to separate a hö here Temperature is required for sealing.

Die Trennschneide, die sich in die elastische Unterlage eindrückt, steht hierbei über die zumindest eine Siegelleiste vor, die sich im wesentlichen nur auf die Unterlage auflegt.The Trennschneide, which presses into the elastic pad, stands over here the at least one sealing strip in front, which is essentially only hangs on the pad.

Bei bekannten Trennschweißstempeln werden die Werkzeuge, nämlich Trennschneide und Siegelleisten über der Länge des Werkzeugsbalkens mehrfach miteinander und mit diesem verschraubt. Da die Vorrichtung üblicherweise bei Umgebungstemperatur montiert wird und die einzelnen Werkzeuge im Betrieb sowohl zwei verschiedene Temperaturen aufweisen sollen als auch gegebenenfalls aus unterschiedlichen Metallen bestehen, kann es im Betrieb im Trennschweißstempel zu mechanischen Verspannungen kommen, die sich nachteilig auf die Dauerhaltbarkeit der Werkzeuge auswirken und gegebenenfalls zu einer verminderten Qualität der Schweiß- und Siegelnähte führen.at known Trennschweißstempeln be the tools, namely Cutting edge and sealing strips over the length of the tool bar several times with each other and bolted to it. There the device usually is mounted at ambient temperature and the individual tools should have two different temperatures during operation and optionally of different metals, It can cause mechanical tension during operation in the separating welding punch come, which is detrimental to the durability of the tools and possibly lead to a reduced quality of the welded and sealed seams.

Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, einen Trennschweißstempel der eingangs genannten Art bereitzustellen, bei dem die vorgenannten Nachteile vermieden werden. Die Lösung hierfür besteht darin, daß die Trennschneide und die zumindest eine Siegelleiste jeweils in ihrer Längsrichtung spannungsfrei längendehnbar im Werkzeugbalken gehalten sind. Hiermit werden Verspannungen auch für den Fall vermieden, daß bei Erreichen der Betriebstemperatur die Trennschneide und die zumindest eine Siegelleiste und gegebenenfalls auch der Werkzeugbalken selber aufgrund verschiedener Werkstoffe und/oder verschiedener Temperaturen jeweils unterschiedlichen Längendehnungen ausgesetzt sind. Das Gesamtwerkzeug bleibt somit spannungsfrei, so daß die Linearität und Parallelität von Trennschneide und der zumindest einen Siegelleiste sichergestellt ist.Of these, Based on the object of the present invention, a separating welding punch to provide the aforementioned type, in which the aforementioned Disadvantages are avoided. The solution for this is that the cutting edge and the at least one sealing strip in each case in their longitudinal direction stretch-free stretchable held in the tool bar. This will also tension for the Case avoided that at Reaching the operating temperature, the cutting edge and the at least a sealing strip and possibly also the tool bar itself due to different materials and / or different temperatures each different length expansions are exposed. The entire tool thus remains tension-free, So that the linearity and parallelism ensured by cutting edge and the at least one sealing strip is.

Die Umsetzung dieser erfindungsgemäßen Lösung ist auf verschiedene Weise möglich. Nach einer ersten Ausgestaltung ist vorgesehen, daß die Trennschneide und/oder die zumindest eine Siegelleiste ausschließlich in ihrer Längsmitte axial im Werkzeugbalken fixiert sind. Damit ist eine ortsfeste Halterung nur in der Längsmitte des jeweiligen Werkzeuges gegeben, das sich bei Erwärmung von hier aus in beide Richtungen gleichmäßig dehnen kann.The Implementation of this solution according to the invention is possible in different ways. According to a first embodiment, it is provided that the separating blade and / or the at least one sealing strip exclusively in their longitudinal center are fixed axially in the tool bar. This is a stationary bracket only in the longitudinal center given of the respective tool, which is heated by can stretch evenly in both directions here.

Nach einer zweiten Ausgestaltung ist vorgesehen, daß die Trennschneide und/oder die zumindest eine Siegelleiste ausschließlich an einem Längsende axial im Werkzeugbalken fixiert ist und am anderen Längsende axial verschieblich, insbesondere mittels einer Zapfen-Langloch-Anordnung im Werkzeugbalken gehalten ist. Hiermit erfolgt die Wärmedehnung von einem festgelegten Ende aus, wobei das andere Ende mit Führungsmitteln gehalten sein muß. Hierfür ist insbesondere ein Zapfen der ein horizontal verlaufendes Langloch durchsetzt, als einfache Umsetzung möglich.To a second embodiment, it is provided that the separating blade and / or the at least one sealing strip exclusively at one longitudinal end axially fixed in the tool bar and at the other longitudinal end axially displaceable, in particular by means of a pin slot arrangement in Tool bar is held. Hereby the thermal expansion takes place from a fixed end, the other end with guide means must be held. Therefor In particular, a pin is a horizontally extending slot interspersed, as a simple implementation possible.

Nach einer dritten Möglichkeit ist vorgesehen, daß die Trennschneide und/oder die zumindest eine Siegelleiste an ihren beiden Längsenden begrenzt axial verschieblich, insbesondere mittels zweier Zapfen-Langloch-Anordnungen im Arbeitbalken gehalten ist. Die Längsverschieblichkeit muß hierbei nur das Maß der Wärmedehnung überschreiten. Auch hier kann die Zapfen-Langloch-Anordnung gewählt werden, während jedoch andere Längsführungsmittel, durch die die Werkzeuge in der Werkzeugaufnahmenut gehalten werden, nicht ausgeschlossen sind.To a third possibility is provided that the Trennschneide and / or the at least one sealing strip on their both longitudinal ends limited axially displaceable, in particular by means of two pin-slot arrangements is held in the working bar. The longitudinal displacement here only the measure of Exceed thermal expansion. Also Here, the pin-slot arrangement can be selected while, however other longitudinal guide means, by which the tools are held in the tool holder groove, are not excluded.

Es ist möglich, die einzelnen Werkzeuge auf unterschiedliche Weise gemäß den vorgeschlagenen Ausführungsformen festzulegen; vorteilhaft ist jedoch die Anwendung gemeinsamer gleichartiger Befestigungsmittel für alle einzelnen Werkzeuge, d. h. die Trennschneide und die zumindest eine Siegelleiste.It is possible to differentiate the individual tools according to the proposed Define embodiments; However, it is advantageous to use common similar fastening means for all individual tools, ie the cutting edge and the at least one sealing strip.

Da die Werkzeuge im Einsatz quer zu ihrer Längserstreckung von unten auf Druck belastet werden, ist es sinnvoll, die Befestigungsmittel im wesentlichen querkraftfrei zu halten, indem die Trennschneide und die zumindest eine Siegelleiste mit ihren Rückenstegen am Grund der Werkzeugaufnahmenut anliegen. Damit werden die Kräfte gleichmäßig auf den Werkzeugbalken verteilt und in diesen eingeleitet.There the tools in use transversely to their longitudinal extent from below Pressure be charged, it makes sense to fastener in the to keep substantial lateral force free by the cutting edge and the at least one sealing strip rest with their back ribs on the bottom of the tool holder. This will be the forces evenly on the Tool bars distributed and initiated in this.

Besonders vorteilhaft ist es, die Trennschneide und die zumindest eine Siegelleiste mit einem Querspiel von insbesondere 0,2 mm in der Werkzeugaufnahmenut einzusetzen; auch dies dient dazu und trägt dazu bei, nachteilige Verformungen infolge von Wärmedehnungen an den Werkzeugen auszuschließen.Especially It is advantageous, the cutting edge and the at least one sealing strip with a transverse play of in particular 0.2 mm in the tool holder groove use; this too serves and contributes to adverse deformations due to thermal expansion to exclude from the tools.

Für die Trennschneide kann bevorzugt Stahl ausgewählt werden, während die zumindest eine Siegelleiste aus Aluminium bestehen kann und insbesondere Teflon beschichtet sein kann. Durch diese unterschiedliche Werkstoffauswahl sind die gewünschten unterschiedlichen Betriebstemperaturen bei Einsatz einer einheitlichen Beheizungsvorrichtung möglich. Hierzu ist im Werkzeugbalken in vorteilhafter Weise eine längsverlaufende Aufnahmekammer vorgesehen, in die zumindest eine elektrische Heizpatrone eingesetzt werden kann.For the cutting edge For example, steel may be selected be while the at least one sealing strip can be made of aluminum and in particular Teflon may be coated. Through these different Material selection are the desired different operating temperatures when using a uniform Heating device possible. For this purpose, in the tool bar advantageously a longitudinal Receiving chamber provided in the at least one electric heating cartridge can be used.

Die Unterlage bzw. Unterstempel ist bevorzugt aus elastischem Material wie Silikon oder einem Elastomer darzustellen, so daß sich die Trennschneide in die Unterlage eindrücken kann, ohne daß die Schärfe der Trennschneide leidet und ohne daß die Unterlage in ihrer Qualität über längere Zeiträume gemindert wird.The Pad or lower punch is preferably made of elastic material such as silicone or an elastomer, so that the Cutting edge can press into the pad without the sharpness of the Trennschneide suffers and without the pad reduced in quality over long periods becomes.

Die Betätigung des Trennschweißstempels kann mit bekannten Mitteln erfolgen, indem der Trennschweißstempel in einem Portal geführt wird und mit einem oder mehreren pneumatischen Zylindern höhenverstellbar ausgestaltet wird. Jeweils mit dem Trennschweißstempel gekoppelt, aber diesem voreilend kann ein Paar Niederhalterleisten angeordnet sein, die die Folienlagen auf dem Unterstempel oder der Unterlage fixieren, bevor die Trennschneide und die Siegelleisten zum Schweißen aufsetzen.The activity the Trennschweißstempels can done by known means by the Trennschweißstempel guided in a portal is height adjustable and with one or more pneumatic cylinders is designed. Each paired with the Trennschweißstempel, but leading the way may be arranged a pair of hold-down strips that the film layers fix on the lower punch or the base before the cutting edge and the sealing strips for welding put on.
