Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Auflegen von Bandmaterial auf einen Arbeitstisch, bestehend aus einem dem Arbeitstisch entlang hin- und herverfahrbaren Legeschlitten, der mit einem Materialspender zur Aufnahme drehbar gelagerter Bandrollen, einer Klemmeinrichtung zum Festhalten eines von einer Bandrolle abziehbaren Bandes und einer Schneideinrichtung zum Ablängen des von einer Bandrolle abgezogenen und auf den Arbeitstisch aufgebrachten Bandes ausgerüstet ist und gegebenenfalls mit einer zum Legeschlitten relativverfahrbaren Halterungseinrichtung zum Niederhalten des Bandanfanges bei Abzugsbeginn zusammenwirkt.The invention relates to a device for placing tape material on a work table, consisting of a laying slide which can be moved back and forth along the work table, which with a material dispenser for receiving rotatably mounted tape rolls, a clamping device for holding a tape that can be pulled off a tape roll, and a cutting device for cutting to length the tape pulled off a tape roll and applied to the work table and optionally cooperating with a holding device which can be moved relatively to the laying slide to hold down the beginning of the tape at the start of the take-off.

Um Bandmaterial, wie Stoffe, Folien od. dgl., maschinell bearbeiten, beispielsweise zuschneiden zu können, muß es auf einen Arbeitstisch aufgelegt werden, wozu es, wie aus der US-A 4 514 246 hervorgeht, bereits eine spezielle Auflegevorrichtung gibt, die sich aus einem einerends des Arbeitstisches vorgesehenen, ein oder zwei Bandrollen aufnehmenden Materialspender und einem über den Arbeitstisch verfahrbaren Legeschlitten zusammensetzt. Der Legeschlitten ist mit einer Klemmeinrichtung ausgerüstet, die den Anfang des aufzulegenden Bandes erfaßt, so daß durch ein Verfahren des Legeschlittens das Band von der jeweiligen Bandrolle abgewickelt und auf den Arbeitstisch gezogen werden kann, wobei eine am Tischende montierte Schneideinrichtung zum Ablängen des abgezogenen Bandes dient. Durch mehrmaliges Hin- und Herfahren des Legeschlittens lassen sich auch mehrere Bandlagen auf dem Arbeitstisch aufschichten und es können auch die Bänder beider Bandrollen gemeinsam aufgelegt werden. Da hier jedoch das Bandmaterial zum Auflegen auf den Arbeitstisch zu ziehen ist und daher über die Tischfläche oder eine untere Materiallage gleiten muß, kommt es häufig zu Schwierigkeiten und vor allem das Auflegen mehrlagiger Materialschichten wird beeinträchtigt und verlangt meist ein Mitverlegen einer Kunststoff-Schutzfolie.In order to machine strip material, such as fabrics, foils or the like, for example to be able to cut it, it must be placed on a work table, for which, as is apparent from US-A 4,514,246, there is already a special laying device which can be used composed of a material dispenser provided at one end of the work table and holding one or two tape rolls and a laying slide that can be moved over the work table. The laying carriage is equipped with a clamping device which detects the beginning of the tape to be placed, so that by a method of Laying slides, the tape can be unwound from the respective tape roll and pulled onto the work table, a cutting device mounted at the end of the table serving to cut the tape that has been pulled off. By repeatedly moving the laying carriage back and forth, several layers of tape can be stacked on the work table and the tapes of both tape rolls can be placed together. However, since here the tape material has to be pulled onto the work table and therefore has to slide over the table surface or a lower layer of material, difficulties often arise and, above all, the application of multilayer material layers is impaired and usually requires the addition of a plastic protective film.

Es sind auch schon verschiedene Auflegevorrichtungen bekannt, bei denen der Legeschlitten selbst den Materialspender aufnimmt und die zum Bandlegen erforderlichen zusätzlichen Einrichtungen, wie Klemmen, Messer, Halterungen u. dgl. trägt, so daß beim Verfahren des Legeschlittens mit einem gleichzeitigen Abwickeln des Bandmaterials ein Bandlegen ohne Zieh- und Gleitbewegungen durch Aufrollen möglich ist. Gemäß der US-A 3 332 681 wurde dabei auch schon ein Materialspender mit mehreren drehbar gelagerten Bandrollen vorgeschlagen, welche Bandrollen der Höhe nach versetzt und hintereinandergereiht am Legeschlitten sitzen und mit an einem oder beiden Legeschlittenenden angeordneten Bandführungseinrichtungen zusammenwirken. Dadurch können zwar den Bandrollen entsprechend viele Bänder gleichzeitig verlegt werden, doch nur als gemeinsame mehrschichtige Lage, und ein Verlegen einzelner Bänder erfordert jeweils ein eigenes händisches Einlegen des Bandes in die Führungseinrichtung, was umständlich und zeitraubend ist. Außerdem ist vor allem bei mehreren Bandrollen ein beträchtlicher Platzbedarf für den Legeschlitten und damit eine entsprechende Überlänge der ganzen Vorrichtung in Kauf zu nehmen.Various laying devices are also known, in which the laying carriage itself receives the material dispenser and the additional devices required for band laying, such as clamps, knives, holders and the like. Like. Carries, so that in the process of laying slides with simultaneous unwinding of the band material, band laying is possible without pulling and sliding movements by rolling up. According to US Pat. No. 3,332,681, a material dispenser with a plurality of rotatably mounted tape rolls has already been proposed, which tape rolls are offset in height and are lined up one behind the other on the laying slide and interact with tape guiding devices arranged on one or both ends of the laying slide. As a result, a large number of tapes can be laid at the same time for the tape rolls, but only as a common multilayered layer, and laying individual tapes requires the tape to be inserted into the guide device by hand, which is cumbersome and time-consuming. In addition, a considerable amount of space for the laying slide and thus a corresponding excess length of the entire device must be accepted, especially in the case of several belt rolls.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Vorrichtung der eingangs geschilderten Art zu schaffen, die auf verhältnismäßig aufwandsarme, rationelle Weise ein schnelles und funktionssicheres Auflegen von Bändern auch unterschiedlichen Materials gewährleistet.The invention is therefore based on the object of eliminating these deficiencies and of creating a device of the type described at the outset which, in a relatively inexpensive and rational manner, ensures that tapes of different materials can be applied quickly and reliably.

Die Erfindung löst diese Aufgabe dadurch, daß der Materialspender eine dreh- und antreibbar im Legeschlitten gelagerte Magazintrommel od. dgl. mit Aufnahmen für wenigstens zwei, vorzugsweise drei Bandrollen umfaßt, wobei die Magazintrommel für jede Bandrolle eine eigene, dieser lagefest zugeordnete Klemme aufweist und durch Drehverstellung jeweils eine Bandrolle und Klemme in eine Abgabestellung schwenkt, in der die im Nahbereich der Arbeitstischfläche sich befindende Klemme das von der zugehörenden Bandrolle abzuziehende Band spitzwinkelig zur Arbeitstischfläche hin ausrichtet und daß die Schneideinrichtung in Abziehrichtung hinter der Abgabestellung der Klemmen am Legeschlitten sitzt und am Legeschlitten zusätzlich eine aus einer Arbeits- in eine Ruhestellung bewegbare, auf das abgezogene Band aufsetzbare Andrückrolle vorgesehen ist. Durch die Kombination von Legeschlitten und Bandmagazin können je nach Bestückung des Magazins große Bandmengen gleichen Materials oder auch unterschiedlichste Bänder ohne Unterbrechung durch einen Bandrollenwechsel aufgelegt und/oder übereinander geschichtet werden. Die betreffenden Bandrollen des Magazins lassen sich dabei durch eine einfache, entsprechend gesteuerte Drehbewegung der Magazintrommel jeweils in die Abgabestellung bringen, aus der dann das Bandmaterial im Maße der Legeschlittenbewegung von der jeweiligen Bandrolle abgewickelt und gleichzeitig auf den Arbeitstisch aufgelegt wird. Das verschiebefreie Auflegen des Bandmaterials auf den Arbeitstisch erlaubt es, Bandmaterial verschiedenster Oberflächenbeschaffenheit und der damit zusammenhängenden Reibungs- und Haftverhältnisse problemlos in ein- oder mehrlagigen Schichten aufzulegen, wobei die Andrückrolle ein sattes, faltenfreies Ablegen der Bänder garantiert und für einen ordnungsgemäßen Abwickelvorgang des abzulegenden Bandes von der jeweiligen Bandrolle sowie gleichzeitig für das rutschsichere Auflegen des Bandes auf der gegebenen Unterlage sorgt. Da jeder Bandrolle eine entsprechende Klemme zugeordnet ist, die den Bandanfang dieser Rolle bis zum eigentlichen Auflegevorgang festhält, kommen zwangsweise durch die Positionierung der jeweiligen Bandrolle in der Abgabestellung auch die Klemme und damit der Bandanfang in eine entsprechende Abgabestellung, so daß nach einem Öffnen der Klemme das Band der in Abgabestellung liegenden Bandrolle freigegeben und durch die offene Klemme auch noch einwandfrei zur Arbeitsfläche hin geführt wird. Um einen störungsfreien Beginn des Bandabzuges sicherzustellen, kann eine Halterungseinrichtung vorgesehen sein, die den Bandanfang nach dem Lösen der Klemme so lange am Arbeitstisch niederhält, bis die Andrückrolle, die anfangs in einer Ruhestellung liegt, sich in Arbeitsstellung auf das Band aufsetzen und niederdrücken läßt. Da die Halterungseinrichtung zum Legeschlitten relativverschiebbar angeordnet und die Schneideinrichtung am Schlitten montiert ist, können Beginn und Ende des jeweiligen Bandauflegevorganges am Arbeitstisch frei gewählt und damit Lage und Länge der aufgelegten Bänder rationell vorbestimmt werden. Der feste Abstand zwischen Schneideinrichtung und der sich in Abgabestellung befindenden Klemmen bringt nach dem Ablängen des Bandes auch stets einen gleichbleibenden Überstand des dann wieder in der Klemme festgehaltenen Bandes und damit zwangsweise auch einen den Beginn eines neuerlichen Ablegevorganges begünstigenden, frei über die Klemme vorkragenden Bandanfang mit sich. Durch die drehverstellbare Magazintrommel entsteht darüber hinaus eine kompakte, aufwandsarme Konstruktion, wobei diese drehbare Magazintrommel sogar den Bandrollenwechsel erleichtert, weil durch eine Trommeldrehung jede Bandrolle geschickt in die geeignetste Wechselposition zu bringen ist.The invention solves this problem in that the material dispenser comprises a magazine drum or the like which is rotatably and driveably mounted in the laying slide and has receptacles for at least two, preferably three, reels, the magazine drum having its own clamp, which is assigned to this position, and by Rotary adjustment pivots a belt roll and clamp into a delivery position, in which the clamp located in the vicinity of the work table surface aligns the belt to be removed from the associated belt roll at an acute angle to the work table surface and that the cutting device sits on the laying carriage and on the laying carriage behind the delivery position of the clamps In addition, a pressure roller which can be moved from a working position into a rest position and can be placed on the pulled-off band is provided. The combination of a laying carriage and a band magazine means that large quantities of the same material or different tapes can be placed and / or stacked on top of each other without interruption by changing the reel, depending on the magazine. The relevant tape reels of the magazine can be brought into the delivery position by a simple, appropriately controlled rotary movement of the magazine drum, from which the tape material is then unwound from the respective tape reel in the amount of the laying slide movement and simultaneously placed on the work table. The shift-free placement of the band material on the work table allows a wide variety of band material Surface quality and the associated friction and adhesion conditions can be easily applied in single or multi-layer layers, whereby the pressure roller guarantees a full, wrinkle-free depositing of the tapes and for a proper unwinding of the tape to be deposited from the respective tape roll and at the same time for the non-slip application of the tape of the given document. Since each reel is assigned a corresponding clamp that holds the beginning of the reel in place until the actual laying process, the positioning of the respective reel in the dispensing position also forces the clamp and thus the beginning of the band into a corresponding dispensing position, so that after opening the clamp the tape of the tape roll lying in the delivery position is released and is also properly guided to the work surface by the open clamp. In order to ensure a trouble-free start of the tape take-off, a holding device can be provided which keeps the beginning of the tape at the work table after releasing the clamp until the pressure roller, which is initially in a rest position, can be placed on the tape and pressed down in the working position. Since the mounting device for the laying slide is arranged to be relatively displaceable and the cutting device is mounted on the carriage, the beginning and end of the respective tape laying process on the work table can be freely selected and the position and length of the tapes placed on it can be rationally predetermined. The fixed distance between the cutting device and the clamps in the delivery position always results in a constant protrusion of the strip that is then held in the clamp after the strip has been cut to length, and thus also inevitably promotes the beginning of a new laying process that freely projects beyond the clamp yourself. The rotatable magazine drum also creates a compact, low-effort design, whereby this rotatable magazine drum even makes changing the reel easier, because each reel can be skillfully brought into the most suitable changing position by rotating the drum.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist wenigstens einer Bandrolle eine dreh- und antreibbar gelagerte Wickeltrommel zum Aufwickeln einer Deckfolie des Bandmaterials od. dgl. zugeordnet, so daß gleichzeitig mit dem Abwickeln des Bandes während des Bandauflegens auf den Tisch eine vorhandene Deckfolie abgezogen und auf die Wickeltrommel aufgewickelt werden kann. Es läßt sich daher auch klebendes, mit einer Schutzfolie abgedecktes Bandmaterial problemlos auflegen und durch das Abziehen der Schutzfolie beim Übereinanderlegen auch gleich miteinander verkleben, was insbesondere beim Auflegen von sogenannten Prepregs oft zweckmäßig ist. Um die Deckfolie od. dgl. aufwickeln zu können, genügt es, zu Beginn die Deckfolie vom Bandmaterial händisch abzuziehen und in die Wickeltrommel einzuspannen, und bei einem Auflegen des Bandes erfolgt dann zwangsweise durch die Aufwickelbewegung der Wickeltrommel das Abziehen der Deckfolie, wobei selbstverständlich der Antrieb der Wickeltrommel an die Abwickelgeschwindigkeit des Bandes angepaßt sein muß.According to a particularly advantageous embodiment of the invention, a rotatable and drivably mounted winding drum for winding up a cover sheet of the strip material or the like is assigned to at least one tape roll, so that an existing cover sheet is pulled off and onto the table while the tape is being unwound while the tape is being laid on the table the winding drum can be wound up. It is therefore also easy to put on adhesive tape material covered with a protective film and, by pulling off the protective film, can also be glued to one another, which is often expedient, particularly when so-called prepregs are put on. In order to be able to wind up the cover film or the like, it is sufficient to pull off the cover film by hand from the tape material and to clamp it in the winding drum, and when the tape is put on, the winding film is then forcibly pulled off the cover film, of course the Drive of the winding drum must be adapted to the unwinding speed of the tape.

Ist die Andrückrolle mit unterschiedlicher Anpreßkraft beaufschlagbar und lagert sie vorzugsweise über Schwenkarme schwenkverstellbar im Legeschlitten, kann sie in ihrer Wirkung an den jeweiligen Vorgang, sei es ein Einzelauflegen eines Bandes oder ein Übereinanderschichten von Bändern, abgestimmt werden und die Schwenkverstellung ermöglicht nicht nur eine einfache Kraftbeaufschlagung der Andrückrolle über einen mit den Schwenkarmen verbundenen Hebel od. dgl., sondern erlaubt es auch, die Andrückrolle aus ihrer Arbeitsstellung in eine den Ablegebereich großräumig freigebende Ruhestellung wegzubewegen.If the pressure roller can be loaded with different contact pressure and is preferably mounted on the swivel arm so that it can be pivoted in the laying carriage, its effect can be coordinated with the respective process, whether it is a single application of a tape or a stacking of tapes, and the swivel adjustment not only enables simple application of force the pressure roller via a lever or the like connected to the swivel arms, but also allows the pressure roller to be removed from its working position to move away to a rest position that releases the storage area.

Günstig ist es weiters, wenn erfindungsgemäß die Halterungseinrichtung aus einer über Auslegerarme schwenkverstellbar an einem Zusatzschlitten od. dgl. angelenkten Halteleiste od. dgl. besteht, die durch Relativverfahren von Lege- und Zusatzschlitten bis in den Ablegebereich zwischen Schneideinrichtung und Abgabestellung der Klemmen vorschiebbar ist. Die Auslegerarme bieten der Halterungseinrichtung eine entsprechende Reichweite, so daß die Halteleiste bei Beginn des Ablegevorganges schwierigkeitslos den über die Klemme vorragenden Bandanfang erfassen und am Arbeitstisch festklemmen kann. Sobald dann das Band durch ein entsprechend weites Verfahren des Legeschlittens soweit abgezogen und abgelegt ist, daß die Andrückrolle in Arbeitsstellung das abgelegte Band erfassen kann, setzt die Andrückrolle auf das Bandmaterial auf und übernimmt die Aufgabe der Halterungseinrichtung, deren Halteleiste durch die Weiterbewegung des Legeschlittens den Ablegebereich verläßt. Beim Fixieren des Bandanfanges bleibt die Halterungseinrichtung gegenüber dem Arbeitstisch ortsfest, sie kann aber je nach Wahl des Auflegebeginns dem Arbeitstisch entlang entsprechend verschoben werden, wozu sie auf einem Zusatzschlitten sitzt.It is also expedient if, according to the invention, the holding device consists of a holding bar or the like articulated on an additional slide or the like which can be pivoted by means of cantilever arms and which can be pushed forward by relative methods of laying and additional slides into the depositing area between the cutting device and the delivery position of the clamps. The cantilever arms offer the holder a corresponding range, so that the holding bar can easily grasp the beginning of the tape protruding from the clamp at the start of the laying process and clamp it on the work table. As soon as the tape is pulled off and put down by a correspondingly wide process of the laying slide so that the pressure roller can grasp the deposited tape in the working position, the pressure roller puts on the tape material and takes over the task of the holding device, the holding strip of which by the further movement of the laying slide Leaves storage area. When fixing the start of the tape, the holding device remains stationary with respect to the work table, but it can be moved along the work table depending on the choice of the starting point, for which purpose it sits on an additional slide.

Ist erfindungsgemäß die Andrückrolle beim Einsatz der Halterungseinrichtung auf die in den Ablegebereich vorragende Halteleiste od. dgl. aufdrückbar, kann die Haltekraft der Halterungseinrichtung über die Andrückrolle aufgebracht werden, welche Andrückrolle dabei außerdem, bedingt durch die Relativbewegung zwischen Lege- und Zusatzschlitten beim Legevorgang, in Drehung versetzt wird und von der Halteleiste auf das abzulegende Band hinüberrollt, so daß eine Störung der Bandablage durch das Aufsetzen der Andrückrolle ausgeschlossen ist.If, according to the invention, the pressure roller can be pressed onto the holding bar or the like protruding into the depositing area when the holding device is used, the holding force of the holding device can be applied via the pressure roller, which pressure roller also depends on the relative movement between the laying and additional slides during the laying process Rotation is offset and rolls over from the holding strip onto the belt to be put down, so that a disturbance of the belt deposit due to the placement the pressure roller is excluded.

Als Zusatzschlitten eignet sich jeder am Arbeitstisch geführte und wunschgemäß positionierbare Schlitten, wobei günstigerweise ein vorhandener Werkzeugschlitten für die Bandbearbeitung als Zusatzschlitten dienen kann. Es ist aber durchaus auch möglich, einen eigenen, über eine längenverstellbare Kupplungseinrichtung am Legeschlitten anhängbaren Zusatzschlitten vorzusehen, so daß Zusatzschlitten und Legeschlitten ein einheitliches Aggregat bilden, aber durch die längenverstellbare Kupplungseinrichtung die erforderliche Relativverschiebung zwischen Lege- und Zusatzschlitten während des Einsatzes der Halterungseinrichtung durchführbar ist.Any slide that is guided on the work table and that can be positioned as desired is suitable as an additional slide, it being possible for an existing tool slide for strip processing to serve as an additional slide. However, it is also entirely possible to provide a separate additional slide which can be attached to the laying slide by means of a length-adjustable coupling device, so that additional slides and laying slides form a unitary unit, but the length-adjustable coupling device can be used to carry out the required relative displacement between laying and additional slides during use of the holding device .

Nach einer vorteilhaften Ausgestaltung der Erfindung können in der Magazintrommel den Klemmen nachgeordnete Führungsschienen vorgesehen sein, die jeweils in Abgabestellung als Querführung für die Schneideinrichtung dienen. Für die Schneideinrichtung läßt sich daher eine zweckmäßige seitliche Warteposition einrichten, in der kein zum Bandverlegen oder Trommeldrehen wertvoller Platz verstellt wird, aus der sie dann aber entlang der jeweiligen Führungsschiene gemäß der Vorschubbewegung zum Ablängen einwandfrei verfahrbar ist. Die Führungsschienen sind wie die Klemmen den Bandrollen fest zugeordnet, so daß unabhängig von der jeweiligen Bandrolle stets gleichbleibende Ablängbedingungen bestehen.According to an advantageous embodiment of the invention, guide rails arranged downstream of the clamps can be provided in the magazine drum, each serving in the delivery position as a transverse guide for the cutting device. For the cutting device it is therefore possible to set up an appropriate lateral waiting position in which no space valuable for laying the tape or rotating the drum is adjusted, but from which it can then be moved along the respective guide rail in accordance with the feed movement for cutting to length. The guide rails, like the clamps, are permanently assigned to the tape rolls, so that there are always constant cutting conditions regardless of the respective tape roll.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise an Hand eines schematischen Längsschnittes durch eine erfindungsgemäße Vorrichtung näher veranschaulicht.In the drawing, the subject matter of the invention is illustrated in more detail, for example, using a schematic longitudinal section through a device according to the invention.

Um Bandmaterial 1 rationell auf einem Arbeitstisch 2 ein- oder mehrlagig auflegen zu können, gibt es einen dem Arbeitstisch 2 entlang verfahrbaren Legeschlitten 3, in dem ein Materialspender 4, der aus einer dreh- und antreibbar gelagerten Magazintrommel 5 zur Aufnahme von drei Bandrollen 6 besteht, sitzt. Die Bandrollen 6, auf denen das Bandmaterial 1 aufgewickelt ist, lagern drehbar in der Magazintrommel 5 und für jede der Bandrollen 6 ist in der Magazintrommel 5 eine eigene Klemme 7 zum Festhalten des jeweiligen Bandanfanges 1a vorgesehen. Durch eine entsprechende Ansteuerung des Drehantriebes 8 für die Magazintrommel 5 läßt sich wunschgemäß jede der drei Bandrollen 6 in eine Abgabestellung A drehen und dort fixieren, in welcher Abgabestellung A die jeweilige Bandrolle 6 im Nahbereich der Arbeitstischfläche 2a liegt und die Klemme 7 das Band 1 spitzwinkelig zu dieser Arbeitsfläche 2a hin ausrichtet.In order to be able to rationally place tape material 1 on a work table 2 in one or more layers, there is one Working table 2 along movable carriage 3, in which a material dispenser 4, which consists of a rotatably and drivably mounted magazine drum 5 for receiving three tape rolls 6, is seated. The tape rolls 6, on which the tape material 1 is wound, are rotatably supported in the magazine drum 5 and for each of the tape rolls 6 a separate clamp 7 is provided in the magazine drum 5 for holding the respective tape start 1a. By correspondingly controlling the rotary drive 8 for the magazine drum 5, each of the three tape rolls 6 can be rotated into a delivery position A and fixed there, in which delivery position A the respective tape roll 6 is in the vicinity of the work surface 2a and the clamp 7 the tape 1 at an acute angle aligned to this work surface 2a.

Der Legeschlitten 3 nimmt zusätzlich zum Materialspender 4 eine Schneideinrichtung 10 auf, die in Abziehrichtung hinter der Abgabestellung A der Bandrollen 6 angeordnet ist und ein entlang von Führungsschienen 9 quer zur Bandrichtung mittels eines Querschlittens 11 verschiebbares Schneidwerkzeug 12 umfaßt. Die jeder Klemme 7 nachgeordneten, in der Magazintrommel 5 abgestützten Führungsschienen 9 bewegen sich mit der Magazintrommel mit und dienen nur jeweils in der Abgabestellung als Querführung für das Schneidwerkzeug 12, so daß dieses Schneidwerkzeug 12 nach einem Schneidvorgang in eine seitliche Warteposition verfahren werden und die Schneideinrichtung 10 weder die Magazintrommelbewegung noch den Bandablegevorgang stören kann.In addition to the material dispenser 4, the laying slide 3 receives a cutting device 10, which is arranged in the pull-off direction behind the delivery position A of the tape rolls 6 and comprises a cutting tool 12 which can be displaced along guide rails 9 transversely to the tape direction by means of a cross slide 11. The guide rails 9, which are arranged downstream of each clamp 7 and are supported in the magazine drum 5, move with the magazine drum and serve only in the delivery position as a transverse guide for the cutting tool 12, so that this cutting tool 12 is moved into a lateral waiting position after a cutting process and the cutting device 10 can neither interfere with the magazine drum movement nor the tape laying process.

Weiters trägt der Legeschlitten 3 eine Andrückrolle 13, die über Schwenkarme 14 schwenkverstellbar gelagert ist und sich aus einer vom Arbeitstisch 2 abgehobenen Ruhestellung in eine Arbeitsstellung schwenken läßt, in der sie knapp hinter der sich in der Abgabestellung A befindenden Klemme 7 auf das abzulegende Band 1 aufgesetzt und gegen die Arbeitstischfläche 2a mit einstellbarer Kraft andrückbar ist.Furthermore, the laying carriage 3 carries a pressure roller 13, which is pivotably mounted via swivel arms 14 and can be swiveled from a rest position lifted from the work table 2 into a working position in which it is placed just behind the clamp 7 in the dispensing position A on the belt 1 to be deposited and can be pressed against the work table surface 2a with an adjustable force.

Um auch den jeweiligen Beginn eines Bandauflegens einwandfrei zu beherrschen, gibt es außer der Andrückrolle 13 noch eine Halterungseinrichtung 15 zum Niederhalten des Bandanfanges 1a, die aus einer über Auslegerarme 16 schwenkverstellbar an einem Zusatzschlitten 17, beispielsweise dem Werkzeugschlitten eines Schneidaggregates 18, angelenkten, in Form eines Führungsbleches ausgebildeten Halteleiste 19 besteht, die durch ein Relativverfahren von Legeschlitten 3 und Zusatzschlitten 17 bis in den Auflegebereich des Bandes 1 vorschiebbar ist, wozu selbstverständlich die Andrückrolle 13 ihre Arbeitsstellung verlassen muß.In order to master the respective beginning of a tape laying perfectly, there is in addition to the pressure roller 13 a holding device 15 for holding down the beginning of the tape 1a, which is articulated in a pivotable manner from an extension arm 16 to an additional slide 17, for example the tool slide of a cutting unit 18 of a guide plate formed retaining strip 19, which can be advanced by a relative movement of the laying slide 3 and additional slide 17 into the lay-up area of the belt 1, for which purpose the pressure roller 13 must of course leave its working position.

Ist das Bandmaterial 1 mit einer Deckfolie 1b versehen, kann diese Deckfolie 1b gleichzeitig beim Auflegen des Bandes 1 abgezogen werden, wenn der jeweiligen Bandrolle 6 in der Magazintrommel 5 eine dreh- und antreibbare Wickeltrommel 20 zugeordnet ist, so daß die gegebenenfalls in die Wickeltrommel 20 vor Ablegebeginn eingespannte Deckfolie 1b durch die angetriebene Wickeltrommel 20 während des Bandauflegens abgezogen und auf die Wickeltrommel aufgewickelt wird und ein deckfolienfreies Band auf den Arbeitstisch 2 aufgelegt werden kann.If the band material 1 is provided with a cover film 1b, this cover film 1b can be removed at the same time when the band 1 is placed on it, if the respective band roll 6 in the magazine drum 5 is assigned a rotatable and drivable winding drum 20, so that the winding drum 20, if appropriate before the start of laying, the cover film 1b which has been clamped is pulled off by the driven winding drum 20 during the laying of the tape and wound onto the winding drum and a tape free of a covering film can be placed on the work table 2.

Zum Bestücken des Materialspenders 4 wird die Magazintrommel 5 entsprechend verdreht, so daß die zu wechselnde oder zu erneuernde Bandrolle 6 problemlos, beispielsweise von oben durch eine Ladeöffnung 21 mittels eines Hebezeuges, ausgetauscht und der jeweilige Bandanfang 1a der neuen Bandrolle in die zugehörende Klemme 7 eingespannt werden kann. Ist der Materialspender bestückt, läßt sich das gewünschte Bandmaterial automatisch auf den Arbeitstisch 2 auflegen, wozu der Legeschlitten 3 in die gewählte Startposition des Auflegevorganges fährt. Die Andrückrolle 13 ist in Ruhestellung, die gewünschte Bandrolle 6 wird in die Abgabestellung A gebracht und die Halterungsvorrichtung 15 vorgeschoben, bis die Halteleiste 19 den Bandanfang 1a erfassen und gegen die Arbeitstischfläche 2a niederdrücken kann. Nun öffnet die Klemme 7 der in der Abgabestellung A liegenden Bandrolle 6 und durch Vorwärtsfahren des Legeschlittens 3 wird das durch die Halterungseinrichtung 15 an der Arbeitstischfläche 2a festgehaltene Band 1 von der Bandrolle 6 abgewickelt und auf die Arbeitstischfläche 2a aufgelegt. Sobald der Legeschlitten 3 genügend weit für den Einsatz der Andrückrolle 13 gefahren ist, schwenkt die Andrückrolle 13 in ihre Arbeitsstellung und übernimmt von der Halterungsvorrichtung 15 die Andrückfunktion beim Auflegen des Bandes 1. Es ist aber auch möglich, die Andrückrolle 13 schon früher in Arbeitsstellung zu bringen und sie dadurch auf die Halteleiste 19 abzusenken, so daß die Haltekraft der Halterungseinrichtung verstärkt oder überhaupt von der Andrückrolle aufgebracht wird und außerdem die Andrückrolle bei Bewegungsbeginn bereits mitgedreht werden und ohne Gleitgefahr auf das Band überrollen kann. Durch das Verfahren des Legeschlittens 3 wird nun das Band 1 unter gleichzeitigem Abwickeln von der Bandrolle 6 ordnungsgemäß im Maße der Schlittenbewegung auf die Arbeitstischfläche 2a aufgelegt, wobei Führungswalzen 7a im Bereich der Klemmen 7 einen vom jeweiligen Rollendurchmesser unabhängigen, gleichmäßigen Bandabzug gewährleisten.To load the material dispenser 4, the magazine drum 5 is rotated accordingly, so that the tape roll 6 to be changed or renewed can be easily replaced, for example from above through a loading opening 21 by means of a hoist, and the respective tape start 1a of the new tape roll clamped in the associated clamp 7 can be. If the material dispenser is equipped, this can be done Place the desired strip material automatically on the work table 2, for which purpose the laying carriage 3 moves into the selected starting position of the laying process. The pressure roller 13 is in the rest position, the desired tape roll 6 is brought into the delivery position A and the holding device 15 is pushed until the holding bar 19 can grip the tape start 1a and press it down against the work table surface 2a. Now the clamp 7 of the tape reel 6 lying in the delivery position A opens and by moving the laying slide 3 forward, the tape 1 held by the holding device 15 on the work table surface 2a is unwound from the tape reel 6 and placed on the work table surface 2a. As soon as the laying carriage 3 has moved sufficiently far for the use of the pressure roller 13, the pressure roller 13 swivels into its working position and takes over the pressure function from the holding device 15 when the tape 1 is put on. However, it is also possible to close the pressure roller 13 earlier in the working position bring and thereby lower them on the holding bar 19, so that the holding force of the holding device is increased or applied at all by the pressure roller and, moreover, the pressure roller can also be rotated at the start of movement and can roll over onto the belt without risk of sliding. By moving the laying slide 3, the tape 1 is now properly laid on the work table surface 2a while simultaneously unwinding from the tape roll 6, with guide rollers 7a in the area of the clamps 7 ensuring a uniform tape take-off which is independent of the respective roller diameter.

Soll außerdem eine eventuell vorhandene Deckfolie 1b vom aufzulegenden Band 1 entfernt werden, wird die Deckfolie 1b, die vor Auflegebeginn händisch abgehoben und in die Wickeltrommel 20 eingespannt wurde, dem Bandabzug gemäß auf die entsprechend schnell angetriebene Wickeltrommel 20 aufgewickelt.If, in addition, any cover film 1b that may be present is to be removed from the tape 1 to be placed, the cover film 1b, which was manually lifted before the start of the laydown and clamped in the winding drum 20, is removed in accordance with the tape take-off wound on the correspondingly rapidly driven winding drum 20.

Ist die gewünschte Bandlänge auf den Arbeitstisch 2 aufgelegt, stoppt der Legeschlitten 3, die Klemmen 7 fixieren das Band 1, die Andrückrolle 13 schwenkt aus der Arbeitsstellung in die Ruhestellung zurück und das Schneidwerkzeug 12 der Schneideinrichtung 10 kann durch eine Querbewegung das aufgelegte Band 1 vom restlichen ablängen, so daß über die Klemme 7 wieder der für den nächsten Auflegevorgang erforderliche Bandanfang 1a vorragt. Nun kann der Legeschlitten für eine Bearbeitung des aufgelegten Bandes in eine Parkposition gefahren oder zum Auflegen mehrlagiger Schichten zur Wiederholung des Auflegevorganges in die Startposition zurückgefahren werden, wobei je nachdem welche Bandrolle 6 in die Abgabestellung A gebracht wird, das gleiche oder ein anderes Band auflegbar ist.If the desired tape length is placed on the work table 2, the laying carriage 3 stops, the clamps 7 fix the tape 1, the pressure roller 13 swivels back from the working position to the rest position and the cutting tool 12 of the cutting device 10 can move the tape 1 from it by a transverse movement Cut the rest to length so that the band start 1a required for the next laying process protrudes again via the terminal 7. The laying carriage can now be moved into a parking position for processing the laid-on band or moved back to the starting position for repeating the layering process to repeat the laying process, the same or a different band depending on which band roll 6 is brought into the delivery position A. .

Durch die freie Verfahrbarkeit des Legeschlittens 3 und des Zusatzschlittens 17 lassen sich der Beginn und auch das Ende des Bandauflegens wunschgemäß wählen, so daß in Lage und Länge, in Materialart und Zahl der aufeinandergeschichteten Lagen beliebiges Bandmaterial auf den Arbeitstisch 2 aufgebracht werden kann. Dabei ist es auch möglich, den Legeschlitten 3 mit einem nur angedeuteten Geräteschlitten 22 zur Aufnahme von Zusatzgeräten od. dgl. auszurüsten und beispielsweise nicht nur zum Auflegen des Bandmaterials, sondern gleichzeitig auch als Trägerschlitten für eine Markierungs- oder Etikettiereinrichtung zum gewünschten Bezeichnen der aufgelegten Bandmaterialien zu nützen.Due to the free travel of the laying carriage 3 and the additional carriage 17, the beginning and the end of the band laying can be chosen as desired, so that any band material can be applied to the work table 2 in position and length, in the type of material and in the number of layers stacked on top of one another. It is also possible to equip the laying carriage 3 with an only indicated device carriage 22 for receiving additional devices or the like and, for example, not only for laying on the strip material, but at the same time also as a carrier slide for a marking or labeling device for the desired identification of the placed strip materials to use.
