Abstract

A packing machine packs the material (2) in a continuous length of flattened tube (1) made from a flexible material. The material (2) is apced evenly along the flattened tube which is passed between two rollers (5,6). Each roller has four radial arms with the end face of each arm forming part of a cylindrical surface which is co-axial with the rotational axes of the roller. The end face of each arm has a number of parallel grooves and ridges formed on its surface. The rollers are so positioned that the ridges of one roller fit into the grooves of the other roller. As the flattened tube passes between the rollers theses ridges and grooves form longitudinal corrugations in the tube and blades (9) attached to the upper roller cut the tube transversely to form separate packets (15). USE/ADVANTAGE - The packets are embossed and cut in one operation.

Description

Die Erfindung betrifft eine Vorrichtung zum gleichzeitigen Trennschneiden und Verprägen, insbesondere von schlauch­ förmiger Verpackungsfolie, die einzelne, zueinander beab­ standete Gegenstände umhüllt. Dabei erfolgt das Trenn­ schneiden und Verprägen in den Lücken zwischen den Gegen­ ständen, so daß letztlich einzeln verpackte Gegenstände anfallen.The invention relates to a device for simultaneous Cutting and stamping, especially of hose shaped packaging film, the individual, spaced apart stood objects wrapped. The separation takes place cut and emboss in the gaps between the counter stand, so that ultimately individually packaged items attack.

Bekannte Vorrichtungen dieser Art bestehen aus zwei Walzen, die aufeinander abrollende Prägebackenpaare tragen. Zwischen den Prägebackenpaaren der einen Walze ist ein Trennmesser angeordnet, zwischen den Prägebackenpaaren der anderen Walze befindet sich eine gehärtete Amboß­ fläche, die als Gegenwerkzeug des Trennmessers dient.Known devices of this type consist of two Rollers that carry pairs of coining dies. There is a between the pairs of stamping jaws of one roller Separating knife arranged between the pairs of stamping jaws the other roller has a hardened anvil surface that serves as the counter tool for the cutting knife.

Nachteilig an dieser hart gegen hart schneidenden Vor­ richtung ist es, daß die Einstellung des Messers äußerst exakt zu erfolgen hat. Geringste Maßänderungen, wie sie durch Messerverschleiß, Temperaturänderung oder ge­ wünschte Veränderungen des Prägedrucks auftreten können, erzwingen bereits eine Korrektur der Messereinstellung.Disadvantage of this hard against hard cutting front The direction is that the setting of the knife is extreme has to be done exactly. Smallest dimensional changes, like them due to knife wear, temperature change or ge desired changes in the embossing pressure can occur, already force a correction of the knife setting.

Aufgabe der Erfindung ist es daher, eine Vorrichtung zum gleichzeitigen Trennschneiden und Verprägen derart aus­ zubilden, daß die Schneidleistung unabhängig von den hier in Frage kommenden Maßänderungen wird. The object of the invention is therefore a device for simultaneous cutting and embossing form that the cutting performance regardless of the dimensional changes in question here.  

Gelöst wird diese Aufgabe der Erfindung dadurch, daß Trennmesser und/oder Gegenwerkzeug über die Präge­ backenpaare hinausragen und daß das Trennmesser aus einem harten, verschleißfesten, das Gegenwerkzeug aus einem weichen, das beschädigungsfreie Eindringen des Trennmessers erlaubenden, Werkstoff besteht.This object of the invention is achieved in that Cutting knife and / or counter tool over the embossing Jaw pairs protrude and that the cutting knife out a hard, wear-resistant, the counter tool a soft, the damage-free penetration of the Cutting knife permitting, material is made.

Der Vorteil dieser Ausgestaltung der Vorrichtung zum gleichzeitigen Trennschneiden und Verprägen liegt darin, daß Maßänderungen der Walzen oder des Trennmessers, wie sie durch Verschleiß oder Temperatur- oder Anpreßdruck­ änderung zustande kommen, ohne Einfluß auf das Schneid­ ergebnis bleiben.The advantage of this design of the device for simultaneous cutting and embossing is that dimensional changes of the rollers or the cutting knife, such as them due to wear or temperature or contact pressure change occur without affecting the cutting remain result.

Weitere Merkmale des Gegenstandes der Erfindung gehen aus den Unteransprüchen sowie aus der nachfolgenden Be­ schreibung eines bevorzugten Ausführungsbeispiels einer Vorrichtung zum gleichzeitigen Trennschneiden und Ver­ prägen von schlauchförmiger Verpackungsfolie, die einzelne, zueinander beabstandete Gegenstände umhüllt, die in den Fig. 1, 2 und 3 der Zeichnung dargestellt ist, hervor.Further features of the object of the invention go from the subclaims and from the following description of a preferred embodiment of a device for simultaneous cutting and Ver embossing tubular packaging film which encases individual, spaced objects, which in FIGS. 1, 2 and 3 of the Drawing is shown.

In der Zeichnung zeigen:The drawing shows:

Die als Ausführungsbeispiel der Erfindung gezeigte Vor­ richtung zum gleichzeitigen Trennschneiden und Verprägen ist einer Maschine zur Herstellung von Damenbinden nach­ geschaltet und stellt dort einen Bestandteil einer An­ lage zur Einzelverpackung dieser Binden dar. In einer dem Erfindungsgegenstand vorgeschalteten und hier nicht dargestellten Einrichtung werden die Binden zunächst in einer Folie eingehüllt. Der dadurch entstehende Schlauch 1 mit den darin enthaltenen, gegenseitig be­ abstandeten Binden 2 wird über eine Transportein­ richtung, bestehend aus den Gurten 3 und 4 den Werk­ zeugen zum gleichzeitigen Verprägen und Trennschneiden zugeführt. Diese bestehen aus zwei Prägewalzen 5 und 6, die jeweils vier beheizbare Prägebackenpaare 7, 7′ und 8, 8′ tragen. Der Bereich zwischen den Prägebackenpaaren 7 und 7′ bzw. 8 und 8′ ist als Nut ausgebildet und dient, im Falle der oberen Prägewalze 5, zur Aufnahme eines Messers 9 im Falle der unteren Walze 6 zur Auf­ nahme eines Gegenwerkzeuges 10, das durch eine weiche, gummiartige Leiste gebildet wird. Das Messer 9 ist aus verschleißfestem, gehärteten Stahl gefertigt und weist, wie aus Fig. 3 ersichtlich, eine gezahnte Klinge auf. Aus fertigungstechnischen Gründen sind die zur Werk­ zeugaufnahme dienenden Nuten in beiden Prägewalzen 5 und 6 gleich breit hergestellt. Das Gegenwerkzeug 10 ist in seiner Breite der aufnehmenden Nut ange­ glichen, das schmale Messer 9 ist zwischen Leisten 11 und 12 gehalten, die die fehlende Breite des Messers ergänzen. Sowohl Messer 9 als auch Gegenwerkzeug 10 sind durch Schrauben 13 in ihren Nuten fixiert. Aus­ gangseitig der Prägewalzen 5 und 6 ist eine weitere Transporteinrichtung 14 zur Abfuhr der nunmehr einzeln verpackten Binden 2′ angeordnet.The device shown as an embodiment of the invention for simultaneous cutting and embossing is connected to a machine for the production of sanitary napkins and there is part of a system for the individual packaging of these sanitary napkins. In a device upstream of the subject of the invention and not shown here, the sanitary napkins are first wrapped in a foil. The resulting hose 1 with the contained, mutually be spaced bandages 2 is supplied via a Transportein direction consisting of the straps 3 and 4 testify to the work for simultaneous stamping and cutting. These consist of two embossing rollers 5 and 6 , each carrying four heatable pairs of embossing jaws 7 , 7 'and 8 , 8 '. The area between the pairs of embossing jaws 7 and 7 'or 8 and 8 ' is formed as a groove and, in the case of the upper embossing roller 5 , for receiving a knife 9 in the case of the lower roller 6 for receiving a counter tool 10 by a soft, rubber-like bar is formed. The knife 9 is made of wear-resistant, hardened steel and, as can be seen in FIG. 3, has a toothed blade. For manufacturing reasons, the grooves used for the tool holder in both embossing rollers 5 and 6 are made the same width. The counter tool 10 is compared in its width of the receiving groove, the narrow knife 9 is held between strips 11 and 12 , which complement the missing width of the knife. Both the knife 9 and the counter tool 10 are fixed in their grooves by screws 13 . From the output side of the embossing rollers 5 and 6 , a further transport device 14 for removing the now individually wrapped bandages 2 'is arranged.

Die Wirkungsweise der soweit in ihren wesentlichen Be­ standteilen beschriebenen Vorrichtung zum gleichzeitigen Trennschneiden und Verprägen ist folgende: Die von einem Folienschlauch 1 umhüllten, gegenseitig beabstandeten Binden 2 werden zwischen den Gurten 3 und 4 den Prägewalzen 5 und 6 zugeführt. Drehzahl und Phasenlage der Prägewalzen sind so gewählt, daß die Prägebackenpaare 7, 7′ und 8, 8′ jeweils mittig im Be­ reich der zwischen den Binden 2 vorhandenen Lücken auf­ einander treffen. Dabei wird nicht nur der Folien­ schlauch 1 querversiegelt, sondern er wird auch gleich­ zeitig quer durchtrennt, da das gezackte Messer 9 wäh­ rend des Abrollvorganges zunächst mit seinen Spitzen und dann zunehmend über seine Gesamtlänge durch den Folienschlauch hindurchstößt und in das als weiche Gummileiste ausgebildete Gegenwerkzeug 10 eindringt. Bei diesem kombinierten Präge/Schneidvorgang ent­ stehen kissenartige Einzelpakete 15, jeweils bestehend aus einer mit Folie umhüllten Einzelbinde. Die aus­ gangseitig der Prägewalzen 5 und 6 angeordnete Trans­ porteinrichtung 14 übernimmt diese Einzelpakete 15 und führt sie einer, hier nicht dargestellten nach­ geschalteten Einrichtung, z. B. einer Verpackungs­ maschine, zu.The operation of the device described so far in its essential components for simultaneous cutting and embossing is as follows: The wrapped by a film tube 1 , mutually spaced bandages 2 are fed between the belts 3 and 4, the embossing rollers 5 and 6 . The speed and phase position of the embossing rollers are selected so that the pairs of embossing jaws 7 , 7 'and 8 , 8 ' each meet in the center of the area between the gaps 2 which are present. Not only is the film tube 1 cross-sealed, but it is also cut transversely at the same time, since the serrated knife 9 during the rolling process first pierces with its tips and then increasingly over its entire length through the film tube and into the counter tool designed as a soft rubber strip 10 penetrates. This combined embossing / cutting process creates cushion-like individual packages 15 , each consisting of an individual bandage wrapped in film. The arranged on the output side of the embossing rollers 5 and 6 trans port device 14 takes over these individual packages 15 and leads them to a switched device, not shown here, for. B. a packaging machine.
