Abstract

A device is proposed for producing expanded flat material, comprising a cutting and expanding device and a coiling device, the starting material for which is a foil web, the expanding device having toothed belt pairs or the like conveyor means guided over partially driven deflection rollers, which conveyor means hold the foil web at the edges and makes it advance and gives the expanded strip a uniform structure over the entire width. This is characterized in that the expanding device on both sides of the foil web has respectively one toothed belt pair that guides the foil web vertically upwards with one lateral edge, starting from the horizontal plane, via hinged, optionally rigid, sliding blocks arranged in the interior area of the toothed belts, while the other lateral edge of the foil web is guided vertically downwards in the same manner, i.e., forming a scissor movement, and an expansion of the foil web is formed across the resulting diagonal.

Description

Die Erfindung betrifft eine Einrichtung zur Herstellung von ebenflächigem Streckmaterial, bestehend aus einer Schneid- und Streckeinrichtung sowie einer Aufrolleinrichtung, dessen Ausgangsmaterial eine Folienbahn ist, die zwischen übereinandergelagerten, aus einzelnen oberen glatten und unteren durch wechselweise Ausnehmungen im Schnittbereich die Schnittlänge bildende Schneidmesser erstellten Schneidwalzen geführt sind, wobei die Streckeinrichtung über teilweise angetrieben Umlenkrollen geführte Zahnriemenpaare oder dgl. Fördermittel verfügt, die die Folienbahn an den Rändern festhält und für den Vortrieb sorgt.The invention relates to a device for the production of planar stretched material, consisting of a cutting and stretching device and a retractor, the starting material is a film web, which led between superimposed, made of individual upper smooth and lower by alternate recesses in the cutting area forming the cutting length cutting blade created cutting rollers are, wherein the stretching device via partially driven pulleys guided toothed belt pairs or the like. Funding has, which holds the film web at the edges and provides the propulsion.

Es ist nach US-A 4 102 024 eine Einrichtung bekannt geworden, die sich mit der Herstellung von Streckmaterial befasst. Hierbei werden eine große Anzahl von Stanzmessern auf die Folienbahn gedrückt und diese gleichzeitig schrittweise nach außen geführt, so dass ein Streckband entsteht. Ein Führungsrad dient zur Zentrierung des Streckbandes. Nachteilig ist, dass eine Seitenhaltung nicht gegeben ist und damit ebene Lagen infolge der Längendifferenzen mit den Rändern nicht erzielbar sind.It is after US-A 4,102,024 a device has become known which deals with the production of expanded material. In this case, a large number of punching blades are pressed onto the film web and at the same time guided stepwise to the outside, so that a stretch band is formed. A guide wheel serves to center the stretch band. The disadvantage is that a lateral position is not given and thus even layers due to the differences in length with the edges are not achievable.

Weiters ist in der US-A 4 486 927 eine Einrichtung zur Herstellung von Streckmaterial aufgezeigt, aus der Schneidwalzen zur Erzielung der Perforation eingesetzt werden. Eine Streckeinrichtung drückt mit einer Anzahl von Streckrädern die Folienbahn schrittweise nach unten, so dass ein Streckband in V-Form entsteht. Auch hier gilt, dass ein ebenflächiges Materialband nicht herstellbar ist.Furthermore, in the US-A 4,486,927 a device for the production of expanded material shown, are used by the cutting rollers to achieve the perforation. A stretching device presses with a number of stretch wheels, the film web gradually down, so that a stretch band in V-shape is formed. Again, it is true that a planar material band can not be produced.

Auch wurde nach EP-A-0 669 176 ein Verfahren und Vorrichtung zur Herstellung von formbeständigen, kugelförmigen Körpern vorgeschlagen, in dem ebenfalls eine Streckeinrichtung vorgesehen ist, um eine Folienbahn zu einem Streckband auszubilden. Hierbei wird ein korrespondierendes oberes und unteres Zahnriemenpaar verwendet, das die Folienbahn an den Rändern festhält und transportiert, wobei zwischen den Riemenpaaren ein nach oben gerichteter Bügel vorgesehen ist, der die Streckung der Folienbahn ermöglicht. Da ein solcher Streckbügel den Nachteil hat, Staubteilchen durch Abrieb zu erzeugen, ist man dazu übergegangen, an Stelle des Streckbügels eine bewegliche Rolle einzusetzen.Also became after EP-A-0 669 176 a method and apparatus for the production of dimensionally stable, spherical bodies proposed in which also a stretching device is provided to form a film web into a stretch band. Here, a corresponding upper and lower timing belt pair is used, which holds and transports the film web at the edges, wherein between the belt pairs an upwardly directed bracket is provided, which allows the stretching of the film web. Because such a Stretch iron has the disadvantage of producing dust particles by abrasion, it has gone over to use a movable role instead of the drawbar.

Um ein gleichmäßiges Stecken zu erzielen, wurde die Rolle zweigeteilt und axial verstellbar ausgebildet. Als Mangel wurde empfunden, dass zwar die Abriebteilchen reduziert wurden, aber in Mitte des Streckbandes Ungleichheiten entstanden sind, d.h. eine gleichmäßige Ausbildung des Streckbandes über die gesamte Breite war nur schwer erzielbar.In order to achieve a uniform insertion, the role was divided into two and made axially adjustable. It was felt to be a shortcoming that, although the debris particles were reduced, but inequalities were created in the middle of the stretched tape, i. a uniform formation of the stretch band over the entire width was difficult to achieve.

Ferner sind aus den Patentschriften US 4 621 397 A , US 4 305 187 A und US 5 088 170 A ähnliche Einrichtungen zu entnehmen, die jedoch nicht auf den Anmeldungsgegenstand zutreffen.Further, from the patents US Pat. No. 4,621,397 A . US Pat. No. 4,305,187 A and US 5 088 170 A similar arrangements, but which do not apply to the subject-matter of the application.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zu Grunde, eine Einrichtung zur Herstellung von ebenflächigem Streckmaterial zu schaffen, die eine Streckeinrichtung enthält, die dem Streckband über die gesamte Breite eine gleichmäßige Struktur verleiht. Erfindungsgemäß wird das Ziel dadurch erreicht, dass die Streckeinrichtung beidseitig der Folienbahn über je ein Zahnriemenpaar verfügt, das die Folienbahn von der Horizontalebene aus, über gelenkig, gegebenenfalls starr ausgebildete, im Innenbereich der Zahnriemen angeordnete Gleitschuhe, mit einem Seitenrand senkrecht nach oben führt, während der andere Seitenrand der Folienbahn in gleicher Weise senkrecht nach unten, d.h. eine Scherenbewegung bildend, geführt ist und eine Streckung der Folienbahn über die entstandene Diagonale gebildet ist.Based on this prior art, the invention was based on the object to provide a device for the production of planar stretched material, which includes a stretching device, which gives the stretch ribbon over the entire width of a uniform structure. According to the invention, the aim is achieved in that the stretching device on both sides of the film web has a respective pair of toothed belts, the film web from the horizontal plane, via articulated, possibly rigid trained, arranged in the inner region of the timing belt shoes, with a side edge vertically upwards, while the other side edge of the film web in the same way vertically downwards, ie forming a scissor movement, is guided and an extension of the film web is formed on the resulting diagonal.

Dadurch wird erreicht, dass ein ebenes Streckband herstellbar ist, das frei von inneren Spannungen ist.This ensures that a flat stretch band can be produced, which is free of internal stresses.

Es ist von Vorteil, wenn die Gleitschuhe Gelenke aufweisen und diese höhenverstellbar sind. Damit kann man unterschiedliche Streckbreiten einstellen.It is advantageous if the sliding blocks have joints and these are adjustable in height. This allows you to set different stretch widths.

Auch ist von Vorteil, wenn der obere Gleitschuh senkrecht zur Zahnriemeninnenseite verschiebbar ausgebildet ist. Hierbei ist es möglich, auf die Materialstärke des Streckbandes Rücksicht zu nehmen.It is also advantageous if the upper slide shoe is designed to be displaceable perpendicular to the toothed belt inner side. It is possible on the Material thickness of the stretch band to take into account.

Auch ist vorteilhaft, wenn die Gleitflächen des oberen Gleitschuhes und des unteren Gleitschuhes im äquidistanten Abstand als gerade Ebenen, bzw. gegebenenfalls mit einem Radius versehene Flächen ausgebildet sind, die einen allmählichen Übergang in die Strecklage zur Folienbahn bilden. Dies ist insofern wichtig, damit die Zahnriemen den Rand der Folienbahn über die gesamt Länge festhalten.It is also advantageous if the sliding surfaces of the upper sliding shoe and the lower sliding shoe are formed at equidistant spacing as straight planes, or optionally provided with a radius surfaces which form a gradual transition into the extended position to the film web. This is important so that the timing belt hold the edge of the film web over the entire length.

Die Fig. 1 zeigt schematisch eine Einrichtung zur Herstellung von Streckbändem, bei der die erfindungsgemäße Streckeinrichtung 10 angeordnet ist. Von einer Vorratstrommel 2, auf der als Ausgangsmaterial ein Folienband 1 aufgewickelt ist, wird dieses zur Schneideinrichtung 3 geführt. Diese Schneideinrichtung 3 besteht im Wesentlichen aus einer übereinandergelagerten oberen Schneidwalze 4 und einer unteren Schneidwalze 5. Die obere Schneidwalze 4 ist als glatte Walze mit Schneidmitteln ausgebildet, während die untere Walze 5 wechselweise Ausnehmungen im Schnittbereich, die Schnittlänge bildend, aufweist. Nachdem die Folienbahn 1 beim Durchlaufen in gleichmäßigen Abständen Schlitze erhalten hat, wird diese an eine Spannvorrichtung 6 geführt. Diese weist eine eingangs angeordnete Umlenkrolle 7 auf, wobei die Folienbahn 1 nach unten zu einer Spannrolle 6 gebracht und hernach nach oben durch Umlenkrolle 8 wieder in horizontale Lage gebracht wird, um dann in die Streckeinrichtung 10 geführt zu werden.Fig. 1 shows schematically a device for the production of drawstrings, in which the stretching device 10 according to the invention is arranged. From a storage drum 2, on which a film strip 1 is wound up as starting material, this is led to the cutting device 3. This cutting device 3 consists essentially of a superimposed upper cutting roller 4 and a lower cutting roller 5. The upper cutting roller 4 is formed as a smooth roller with cutting means, while the lower roller 5 alternately recesses in the cutting area, forming the cut length has. After the film web 1 has received slots when passing through at regular intervals, it is guided to a tensioning device 6. This has an initially arranged deflection roller 7, wherein the film web 1 is brought down to a tensioning roller 6 and then brought up again by deflection roller 8 in a horizontal position, to then be guided into the stretching device 10.

Die Streckeinrichtung 10 enthält an jeder Seite im Wesentlichen ein Zahnriemenpaar 18,19, das über eine Reihe von Umlenkrollen 11 bis 17 geführt und an den Rändern der Folienbahn 1 positioniert ist. So ist der obere Zahnriemen 18 um die Umlenkrollen 11,13 und 15 geführt, wobei nach außen die Zähne der Zahnriemenseite 20 weisen. Die Zahnriemenseite 21 hingegen ist glatt und liegt an der Innenseite. Desgleichen ist der untere Zahnriemen 19 über die Umlenkrolle 12,14 und 16,17 geführt. Auch hier ist der Zahnriemen 19 nach außen verzahnt, während die Innenseite wiederum glatt ausgebildet ist. Die Zahnriemenpaare 18,19 stehen zwischen den Umlenkwalzen 11,12 und 13,14 im Eingriff und halten an den Rändern die Folienbahn 1 fest. An Stelle der Zahnriemen können auch Zahnketten oder dgl. Fördermittel verwendet werden. In Mitte der Streckeinrichtung 10 befindet sich ein oberer Gleitschuh 22 und ein unterer Gleitschuh 23. Der obere Gleitschuh 22 weist eine Führung auf, die mit einer geraden Ebene, gegebenenfalls einem Radius R, den Rand der Folienbahn 1 von der Umlenkrolle 11 zur Umlenkrolle 13 führt.The stretching device 10 includes on each side substantially a toothed belt pair 18,19, which is guided over a series of deflection rollers 11 to 17 and positioned at the edges of the film web 1. Thus, the upper toothed belt 18 is guided around the pulleys 11,13 and 15, wherein outwardly the teeth of the Have toothed belt side 20. The toothed belt side 21, however, is smooth and lies on the inside. Similarly, the lower toothed belt 19 is guided over the deflection roller 12,14 and 16,17. Again, the timing belt 19 is toothed to the outside, while the inside is again smooth. The toothed belt pairs 18,19 are between the guide rollers 11,12 and 13,14 in engagement and hold the film web 1 at the edges. In place of the toothed belt, toothed chains or the like can be used. In the middle of the stretching device 10 is an upper shoe 22 and a lower shoe 23. The upper shoe 22 has a guide that leads with a straight plane, optionally a radius R, the edge of the film web 1 of the guide roller 11 to the guide roller 13 ,

Im äquidistanten Abstand ist die Führung auch im unteren Gleitschuh 23 vorhanden, derart, dass die beiden Zahnriemen 18,19 im Eingriff stehen und dazwischen der Rand der Folienbahn 1 liegt. Eine der Umlenkrollen, z.B. 11, ist als Antriebsrolle ausgebildet.In the equidistant distance, the guide is also present in the lower sliding shoe 23, such that the two toothed belts 18, 19 are in engagement and the edge of the film web 1 lies therebetween. One of the pulleys, e.g. 11, is formed as a drive roller.

Vorteilhaft ist auch die untere Umlenkrolle 12 als Antriebsrolle auszubilden, um einen gleichmäßigen Zug der Riemenpaare 18,19 zu gewährleisten. Der obere Gleitschuh 22 hat noch eine Verstelleinrichtung 24, um diesen senkrecht zur Innenseite des Zahnriemens 18 auszurichten und den Anpressdruck variieren zu können.It is also advantageous to form the lower deflection roller 12 as a drive roller in order to ensure a uniform pull of the belt pairs 18, 19. The upper sliding shoe 22 still has an adjusting device 24 in order to align it perpendicular to the inside of the toothed belt 18 and to be able to vary the contact pressure.

Der untere Zahnriemen 19 läuft nun über die bereits erwähnte Umlenkrolle 12, die als Antriebsrolle ausgebildet sein kann und wird über die Umlenkrollen 14,16,17 geführt. Es ist aber auch möglich, den Antrieb über ein Ritzel 33 auf die Zahnriemenseite 20 zu übertragen, weil man dadurch nur einen Antriebsstrang braucht. Im Bereich des oberen Gleitschuhes 22 ist nun der untere Gleitschuh 23 starr am Maschinenrahmen befestigt.The lower toothed belt 19 now runs over the already mentioned deflection roller 12, which may be formed as a drive roller and is guided over the deflection rollers 14,16,17. But it is also possible to transfer the drive via a pinion 33 on the timing belt side 20, because you only need a drive train. In the area of the upper sliding shoe 22, the lower sliding shoe 23 is now fixed rigidly to the machine frame.

An der gegenüberliegenden Seite der Streckeinrichtung 10 - in der Zeichnung zum besseren Verständnis strichliniert angegeben - ist in gleicher Weise ein Zahnriemenpaar 18,19 angeordnet, das nun an den Rand der anderen Seite der Folienbahn 1 eingreift. Der Unterschied besteht aber darin, dass der Rand der Folienbahn 1 nach unten geführt wird. Die Anordnung der Umlenkrollen ist zwar gleich, jedoch auf den Kopf gestellt. Desgleichen gilt für die Gleitschuhe 22,23. Am Eingang der Streckeinrichtung 10 ist die Folienbahn 1 eben, wird durch Zahnriemen 18,19 ergriffen und mit der einen Seite durch die Gleitschuhe 22,23 und die Anordnung der Umlenkwalzen 13,14 nach oben geführt. An der gegenüberliegenden Seite wird das Riemenpaar 18,19 durch die Lage der Umlenkrollen 31,32 nach unten geführt. Durch den Eingriff der Zahnriemenpaare 18,19 wird an den Rändern eine zahnartiges Profil erstellt, das bei der seitlichen Dehnung des Folienbandes 1 die Längenänderung bei der Streckung ausgleicht und somit ein ebenes Streckband ergibt. Die aus der Streckeinrichtung 10 herausgeführte Folienbahn 1 a kommt nun auf eine Umlenkung 25, die aus einem übereinandergelagerten glatten Walzenpaar 26,27 besteht. Diese ist insofern wichtig, damit die Restspannungen eliminiert werden. Hernach kommt die gestreckte Folienbahn 1 a auf eine Aufnahmetrommel 28.On the opposite side of the stretching device 10 - indicated by dashed lines in the drawing for ease of understanding - a toothed belt pair 18,19 is arranged in the same way, now to the edge of the other side of the Film web 1 engages. The difference, however, is that the edge of the film web 1 is guided downwards. Although the arrangement of the pulleys is the same, but upside down. The same applies to the sliding blocks 22,23. At the entrance of the stretching device 10, the film web 1 is flat, is gripped by toothed belts 18,19 and guided with one side by the sliding blocks 22,23 and the arrangement of the guide rollers 13,14 upwards. On the opposite side of the belt pair 18,19 is guided by the position of the pulleys 31,32 down. Through the engagement of the toothed belt pairs 18,19 a tooth-like profile is created at the edges, which compensates for the lateral expansion of the film strip 1, the change in length during stretching and thus results in a flat stretch band. The led out of the stretching device 10 film web 1 a now comes to a deflection 25, which consists of a superimposed smooth pair of rollers 26,27. This is important in that the residual stresses are eliminated. Afterwards, the stretched film web 1a comes onto a take-up drum 28.

Gemäß Schnitt A - A der Fig. 1 ist in Fig. 2 die Vorderansicht der Streckeinrichtung 10 aufgeführt. In Mitte ist die Folienbahn 1, wie sie in die Steckeinrichtung 10 eingebracht wird. Durch die Anordnung der Zahnriemenpaare 18,19 und der damit erforderlichen Umlenkrollen sowie der Gleitschuhe 22,23 wird der Rand der Folienbahn 1 nach oben gedrückt und in gleicher Weise an der anderen Seite des Randes nach unten gebracht. Durch diese Breitenänderung werden die in der Folienbahn 1 eingebrachten Schlitze erweitert. Vorteilhafterweise beträgt dies Streckung das 5-fache, vorzugsweise das 3-fache der ursprünglichen Breite. Dies hängt in erster Linie von der Materialbeschaffenheit, aber auch von der gewählten Schnittlänge der Folienbahn 1 ab. Hierbei sind die Umlenkrollen 13,14,17 sowie die Gleitschuhe 22,23 für den nach oben geführten Rand der Folienbahn 1 angeordnet, während für den nach unten geführten Rand die Umlenkrollen 31,32 dienen.According to section A - A of FIG. 1, the front view of the stretching device 10 is shown in FIG. In the middle, the film web 1, as it is introduced into the plug-in device 10. Due to the arrangement of the toothed belt pairs 18,19 and the deflection rollers and the sliding blocks 22,23 thus required, the edge of the film web 1 is pushed up and brought in the same way on the other side of the edge down. As a result of this change in width, the slits introduced in the film web 1 are widened. Advantageously, this stretch is 5 times, preferably 3 times, the original width. This depends primarily on the material properties, but also on the selected cutting length of the film web 1 from. Here, the pulleys 13,14,17 and the sliding blocks 22,23 are arranged for the upwardly led edge of the film web 1, while for the guided down edge the pulleys 31,32.

Die Fig. 3 zeigt eine Variante der Streckeinrichtung 10, deren Gleitschuhe 30 durch ein Gelenk 29 gemäß Pfeile beweglich ausgebildet sind. Diese können sich gut an die Führung der Zahnriemenpaare 18,19 angleichen. Im Übrigen gelten die gleichen Bezugszeichen für die Umlenkrollen wie schon in Fig. 1 erwähnt. Für den oberen Zahnriemen 18 sind die Umlenkrollen 11,13,15, zuständig, während die Umlenkrollen für den unteren Zahnriemen 19 die Bezugszeichen 12,14,16 und 17 im Bewegungsrichtung gesehen, haben. Desgleichen gilt für die andere Seite, die dann für den nach unten geführten Rand über die Umlenkrollen 31,32 laufen. Auch hier ist die andere Seite der Streckeinrichtung strichliniert angegeben.Fig. 3 shows a variant of the stretching device 10, the sliding blocks 30 are designed to be movable by a hinge 29 according to arrows. These can be adapted well to the guidance of the timing belt pairs 18,19. Incidentally, the same reference numerals for the pulleys apply as already mentioned in Fig. 1. For the upper one Timing belt 18 are the pulleys 11,13,15, responsible, while the pulleys for the lower toothed belt 19, the reference numerals 12,14,16 and 17 seen in the direction of movement, have. The same applies to the other side, which then run over the deflection rollers 31, 32 for the edge guided downwards. Again, the other side of the stretching device is indicated by dashed lines.

Die Fig. 4 zeigt die Ausbildung und Lage der Zahnriemen 18,19, die an der Stelle mit der Bezeichnung B in Fig. 1 angeordnet sind. Die Zähne sind im gegenseitige Eingriff und dazwischen liegt die Folienbahn 1, die nun die Zahnform annimmt. Die äußeren Seiten der Zahnriemen 18,19 sind mit glatter Zahnriemenseite 21 versehen.Fig. 4 shows the formation and position of the timing belt 18,19, which are arranged at the location with the name B in Fig. 1. The teeth are in mutual engagement and in between is the film web 1, which now assumes the tooth shape. The outer sides of the toothed belts 18, 19 are provided with a smooth toothed belt side 21.

Der wesentliche Vorteil dieser Streckeinrichtung 10 besteht darin, dass diese einfach im Aufbau ist, variabel anpassbar und darüber hinaus eine gleichmäßige Struktur über die gesamte Breite der gestreckten Folienbahn 1 a ergibt. Dies ist aber die Voraussetzung für den vielseitigen Einsatz solcher Streckbänder.The essential advantage of this stretching device 10 is that it is simple in construction, variably adaptable and moreover results in a uniform structure over the entire width of the stretched film web 1 a. But this is the prerequisite for the versatile use of such stretch bands.
