Die vorliegende Erfindung betrifft eine Sägemaschine zum Zersägen zumindest eines plattenförmigen Werkstücks, in Form einer Platte oder eines Plattenstapels, mit einer, entlang einer, insbesondere geraden, Schnittlinie verfahrbaren Sägeeinrichtung zum Durchtrennen des auf einem Maschinentischbereich der Sägemaschine aufliegenden plattenförmigen Werkstücks und mit zumindest einer Vorschubeinrichtung zum Transport des plattenförmigen Werkstücks auf dem Maschinentischbereich in zumindest einer Richtung parallel zu einer hin zur Schnittlinie gerichteten Transportrichtung.The present invention relates to a sawing machine for sawing at least one plate-shaped workpiece, in the form of a plate or a stack of plates, with a, along a straight, cutting line movable sawing device for severing the lying on a machine table area of the sawing machine plate-shaped workpiece and with at least one feed device for Transport of the plate-shaped workpiece on the machine table area in at least one direction parallel to a directed towards the cutting line transport direction.
Gattungsgemäße Sägemaschinen werden auch häufig als sogenannte Plattenaufteilanlagen bezeichnet. Mit ihnen können plattenförmige Werkstücke aus unterschiedlichstem Material wie Holz, Kunststoff, Metall und diversen Verbundmaterialien zersägt werden. Beim plattenförmigen Material kann es sich um Einzelplatten aber auch um Plattenstapel handeln. Eine gattungsgemäße Sägemaschine ist z.B. in der
Aufgabe der Erfindung ist es, einen Vorschlag zu machen, wie Sägemaschinen der eingangs genannten Art verbessert werden können, um vielfältiger einsetzbar zu sein.The object of the invention is to make a proposal as sawing machines of the type mentioned can be improved to be more versatile.
Erfindungsgemäß wird dies erreicht, indem die Sägemaschine zumindest einen zusätzlichen Maschinentischbereich mit zumindest einer zusätzlichen Vorschubeinrichtung für zumindest ein, vorzugsweise stangen- oder rohrförmiges, sonstiges Werkstück aufweist, wobei eine maximale Vorschublänge der zusätzlichen Vorschubeinrichtung, gemessen parallel zur Transportrichtung zwischen der Schnittlinie und einer von der Schnittlinie maximal entfernten Betriebsstellung der zusätzlichen Vorschubeinrichtung, größer ist als eine maximale Vorschublänge der Vorschubeinrichtung, gemessen parallel zur Transportrichtung zwischen der Schnittlinie und einer von der Schnittlinie maximal entfernten Betriebsstellung der Vorschubeinrichtung.According to the invention this is achieved by the sawing machine has at least one additional machine table area with at least one additional feed device for at least one, preferably rod or tubular, other workpiece, wherein a maximum feed length of the additional feed device, measured parallel to the transport direction between the cutting line and one of the Cutting line maximum remote operating position of the additional feed device, is greater than a maximum feed length of the feed device, measured parallel to the transport direction between the cutting line and a maximum of the cutting line remote operating position of the feed device.
Die Erfindung schlägt somit eine Art Kombinationssäge vor, mit welcher sowohl plattenförmige Werkstücke als auch sonstige, vorzugsweise stangen- oder rohrförmige, Werkstücke zersägt werden können. Die genannten Arten von Werkstücken werden dabei von der Vorschubeinrichtung und auch von der zusätzlichen Vorschubeinrichtung derselben Schnittlinie und damit auch derselben Sägeeinrichtung zugeführt. Man könnte somit auch von einer gemeinsamen Schnittlinie bzw. einer gemeinsamen Sägeeinrichtung sprechen. Dabei sei darauf hingewiesen, dass erfindungsgemäße Sägemaschinen grundsätzlich auch mehrere Schnittlinien und mehrere Sägeeinrichtungen aufweisen können. Die genannte Schnittlinie bzw. gemeinsame Schnittlinie ist dann die, bei der mittels Vorschubeinrichtung und zusätzlicher Vorschubeinrichtung die entsprechenden Werkstücke zu eben jener Schnittlinie zuführbar sind.The invention thus proposes a kind of combination saw, with which both plate-shaped workpieces and other, preferably rod-shaped or tubular, workpieces can be sawn. The said types of workpieces are supplied from the feed device and also from the additional feed device of the same cutting line and thus also the same sawing device. One could therefore also speak of a common cutting line or a common sawing device. It should be noted that sawing machines according to the invention can in principle also have a plurality of cutting lines and a plurality of sawing devices. The said cutting line or common cutting line is then the one in which the corresponding workpieces can be fed to just that cutting line by means of feed device and additional feed device.
Die Erfindung bietet sich insbesondere dann an, wenn man einerseits die genannten plattenförmigen Werkstücke zersägen bzw. in kleinere Teilplatten aufteilen muss und andererseits aber auch besonders lange, insbesondere stangen- oder rohrförmige, Werkstücke zersägen muss. Diese stangen- bzw. rohrförmigen Werkstücke können Dank der Erfindung wesentlich länger sein, als die größte Kantenlänge des größten plattenförmigen Werkstücks, für die der Maschinentischbereich der Sägemaschine ausgelegt ist.The invention is particularly suitable when one has to saw the said plate-shaped workpieces on the one hand or divide them into smaller part plates on the other hand but also has to saw workpieces of particularly long, in particular rod-shaped or tubular ones. This rod or tubular Workpieces can be much longer thanks to the invention, as the largest edge length of the largest plate-shaped workpiece, for which the machine table area of the sawing machine is designed.
Der Vollständigkeit halber wird darauf hingewiesen, dass erfindungsgemäße Sägemaschinen somit zumindest zwei Maschinentischbereiche, eben den Maschinentischbereich und den zusätzlichen Maschinentischbereich und zumindest zwei Vorschubeinrichtungen, eben die Vorschubeinrichtung und die zusätzliche Vorschubeinrichtung aufweisen. Insofern könnte der Maschinentischbereich, der der Auflage und dem Transport der plattenförmigen Werkstücke dient, auch als erster Maschinentischbereich und die Vorschubeinrichtung, die die plattenförmigen Werkstücke auf diesem ersten Maschinentischbereich bewegt, auch als erste Vorschubeinrichtung bezeichnet werden.For the sake of completeness it is pointed out that sawing machines according to the invention thus have at least two machine table areas, namely the machine table area and the additional machine table area and at least two feed devices, precisely the feed device and the additional feed device. In this respect, the machine table area which serves to support and transport the plate-shaped workpieces could also be referred to as the first feed device as the first machine table area and the feed device which moves the plate-shaped workpieces on this first machine table area.
Zur Transportrichtung sei darauf hingewiesen, dass es sich dabei um die Richtung handelt, in der die auf dem Maschinentischbereich aufliegenden plattenförmigen Werkstücke und auch die im zusätzlichen Maschinentischbereich aufliegenden sonstigen Werkstücke mittels der jeweiligen Vorschubeinrichtung zum Zersägen hin zur Schnittlinie transportiert werden. Vor oder nach dem Sägevorgang, welcher in der Regel orthogonal zur Transportrichtung entlang der Schnittlinie erfolgt, werden die dann zersägten plattenförmigen und/oder sonstigen Werkstücke in Transportrichtung weiter, dann eben von der Schnittlinie weg, transportiert. Die Vorschubeinrichtung und die zusätzliche Vorschubeinrichtung haben also dieselbe Transportrichtung bzw. zumindest zueinander parallele und in dieselbe Richtung weisende Transportrichtungen. Der Maschinentischbereich und auch der zusätzliche Maschinentischbereich sind in Transportrichtung gesehen vor der Schnittlinie angeordnet. In Transportrichtung gesehen hinter der Schnittlinie befindet bzw. befinden sich vorzugsweise ein oder mehrere Ablagetische, auf denen das oder die hinter die Schnittlinie transportierte bzw. transportierten Werkstücke zu liegen kommen.Regarding the transport direction, it should be noted that this is the direction in which the plate-shaped workpieces lying on the machine table area and also the other workpieces resting in the additional machine table area are transported by means of the respective feed device for sawing up to the cutting line. Before or after the sawing process, which is usually orthogonal to the transport direction along the cutting line, the then sawed plate-shaped and / or other workpieces in the transport direction, then just away from the cutting line transported. The feed device and the additional feed device thus have the same transport direction or at least parallel to each other and pointing in the same direction transport directions. The machine table area and also the additional machine table area are arranged in the transport direction before the cutting line. As seen in the transport direction behind the cutting line is or are preferably one or more delivery tables on which come or lie behind the cutting line transported or transported workpieces.
Die Maschinentischbereiche, auf denen die plattenförmigen und/oder sonstigen Werkstücke aufliegen, sind günstigerweise, wie an sich bekannt, mit geeigneten Einrichtungen zur Reduzierung der beim Transport mittels der Vorschubeinrichtungen auftretenden Reibungskräfte ausgerüstet. Dies können Rollen, Walzen, Luftkissen und dergleichen sein. Hierzu sind beim Stand der Technik verschiedene Varianten bekannt, die alle im Rahmen von erfindungsgemäßen Sägemaschinen angewendet bzw. realisiert werden können.The machine table areas on which rest the plate-shaped and / or other workpieces are conveniently, as is known, equipped with suitable means for reducing the friction forces occurring during transport by means of the feed devices. These may be rollers, rollers, airbags and the like. For this purpose, various variants are known in the prior art, all of which can be applied or realized in the context of sawing machines according to the invention.
Um zusätzlich zu den plattenförmigen Werkstücken auch entsprechend lange sonstige Werkstücke zersägen zu können, sehen bevorzugte Ausgestaltungsformen der Erfindung vor, dass die maximale Vorschublänge der zusätzlichen Vorschubeinrichtung zumindest 1,5 mal, vorzugsweise zumindest 2 mal, so groß ist, wie die maximale Vorschublänge der Vorschubeinrichtung.In order to be able to saw other workpieces correspondingly long in addition to the plate-shaped workpieces, preferred embodiments of the invention provide that the maximum feed length of the additional feed device is at least 1.5 times, preferably at least 2 times, as large as the maximum feed length of the feed device ,
Grundsätzlich ist es denkbar, dass der Maschinentischbereich mit der Vorschubeinrichtung und der zusätzliche Maschinentischbereich mit der zusätzlichen Vorschubeinrichtung getrennt voneinander ausgeführt sind. In der Regel sind dann der Maschinentischbereich und der zusätzliche Maschinentischbereich parallel zueinander nebeneinander angeordnet.In principle, it is conceivable that the machine table area with the feed device and the additional machine table area with the additional feed device are designed separately from one another. As a rule, the machine table area and the additional machine table area are then arranged parallel to one another next to one another.
Bevorzugte Ausgestaltungsformen der Erfindung sehen jedoch vor, dass der Maschinentischbereich in einer Querrichtung orthogonal zur Transportrichtung gesehen einen Arbeitsbereich aufweist, innerhalb dem das plattenförmige Werkstück auf den Maschinentischbereich anordenbar und von der Vorschubeinrichtung transportierbar ist, wobei der zusätzliche Maschinentischbereich gegenüber dem Maschinentischbereich in Richtung parallel zur Transportrichtung verlängert ist und innerhalb des Arbeitsbereichs des Maschinentischbereichs liegt.However, preferred embodiments of the invention provide that the machine table area has a working area in a transverse direction orthogonal to the transport direction, within which the plate-shaped workpiece can be arranged on the machine table area and transported by the feed device, wherein the additional machine table area relative to the machine table area in the direction parallel to the transport direction is extended and within the working range of the machine table area.
Dabei ist günstigerweise vorgesehen, dass der Arbeitsbereich der Vorschubeinrichtung und ein zusätzlicher Arbeitsbereich der zusätzlichen Vorschubeinrichtung sich, in Querrichtung orthogonal zur Transportrichtung gesehen, überlappen. Beim Arbeitsbereich und auch beim zusätzlichen Arbeitsbereich handelt es sich letztendlich um die maximal mögliche Arbeitsbreite, mit der die jeweilige Vorschubeinrichtung, also die Vorschubeinrichtung bzw. die zusätzliche Vorschubeinrichtung die plattenförmigen Werkstücke oder die sonstigen Werkstücke im Maschinentischbereich bzw. zusätzlichen Maschinentischbereich bewegen können. Die jeweiligen Arbeitsbereiche bzw. Arbeitsbreiten werden orthogonal zur Transportrichtung, also in Querrichtung bestimmt. Nachdem in diesen Ausgestaltungsformen auch zumindest zwei Arbeitsbereiche, nämlich der Arbeitsbereich und der zusätzliche Arbeitsbereich vorhanden sind, könnte der Arbeitsbereich der Vorschubeinrichtung bzw. ersten Vorschubeinrichtung analog zu oben auch als erster Arbeitsbereich bezeichnet werden. Besonders günstige Ausgestaltungsformen dieser Art sehen vor, dass der zusätzliche Arbeitsbereich der zusätzlichen Vorschubeinrichtung in einem Randbereich des Arbeitsbereichs der Vorschubeinrichtung angeordnet ist.It is advantageously provided that the working range of the feed device and an additional working range of the additional feed device, in the transverse direction orthogonal to the transport direction seen, overlap. The work area and also the additional work area is ultimately the maximum possible working width with which the respective feed device, ie the feed device or the additional feed device can move the plate-shaped workpieces or other workpieces in the machine table area or additional machine table area. The respective work areas or working widths are determined orthogonal to the transport direction, ie in the transverse direction. Since in these embodiments, at least two work areas, namely the work area and the additional work area are available, the work area of the feed device or first feed device could also be referred to as the first work area analogous to above. Particularly favorable embodiments of this type provide that the additional working area of the additional feed device is arranged in an edge area of the working area of the feed device.
Damit die Vorschubeinrichtungen, also die Vorschubeinrichtung und die zusätzliche Vorschubeinrichtung, das jeweilige Werkstück greifen, transportieren und auch z.B. während des Sägevorgangs festhalten können, sehen bevorzugte Ausgestaltungsformen der Erfindung vor, dass die Vorschubeinrichtung eine oder mehrere Greifeinrichtungen zum Greifen eines plattenförmigen oder eines sonstigen Werkstücks und/oder die zusätzliche Vorschubeinrichtung eine oder mehrere Greifeinrichtungen zum Greifen eines plattenförmigen oder eines sonstigen Werkstücks aufweist bzw. aufweisen. Solche Greifeinrichtungen zum Greifen eines Werkstücks sind beim Stand der Technik an sich bekannt und müssen daher eigentlich nicht näher erläutert werden. Die Greifeinrichtungen können z.B. einen unteren und einen oberen Klemmfinger aufweisen, wobei die Klemmfinger relativ zueinander verfahrbar sind, sodass zwischen den Klemmfingern das zu transportierende und zu zersägende Werkstück eingeklemmt werden kann.Thus, the feed devices, so the feed device and the additional feed device, the respective workpiece grip, transport and also, for example. During the sawing process, preferred embodiments of the invention provide that the feed device has or have one or more gripping devices for gripping a plate-shaped or other workpiece and / or the additional feed device one or more gripping devices for gripping a plate-shaped or other workpiece , Such gripping means for gripping a workpiece are known per se in the prior art and therefore do not actually need to be explained in detail. The gripping devices may e.g. have a lower and an upper clamping finger, wherein the clamping fingers are movable relative to each other, so that between the clamping fingers, the workpiece to be transported and to be sawn can be clamped.
In diesem Zusammenhang sei aber auch darauf hingewiesen, dass Vorschubeinrichtungen nicht zwangsläufig Greifeinrichtungen haben müssen. Auch hier sind Alternativen beim Stand der Technik bekannt. Soweit sinnvoll, können diese auch im Zuge der Realisierung der Erfindung angewendet werden.In this context, it should also be noted that feed devices do not necessarily have to have gripping devices. Also Here are alternatives known in the art. If appropriate, they can also be used in the course of implementing the invention.
Soweit entsprechende Greifeinrichtungen vorhanden sind, ist es jedenfalls günstig, wenn die Vorschubeinrichtung, in Querrichtung orthogonal zur Transportrichtung gesehen, einen Arbeitsbereich aufweist und die Greifeinrichtung(en) der zusätzlichen Vorschubeinrichtung in diesen Arbeitsbereich der Vorschubeinrichtung eingreifen können. Entsprechend ist es auch günstig, wenn die zusätzliche Vorschubeinrichtung, in Querrichtung orthogonal zur Transportrichtung gesehen, einen zusätzlichen Arbeitsbereich aufweist und die Greifeinrichtung(en) der Vorschubeinrichtung in diesen zusätzlichen Arbeitsbereich der zusätzlichen Vorschubeinrichtung eingreifen können. Damit die Vorschubeinrichtungen samt Greifeinrichtungen auch über auf dem jeweiligen Maschinentischbereichen aufliegende Werkstücke hinwegfahren können, sehen bevorzugte Ausgestaltungsformen der Erfindung wie an sich bekannt vor, dass die Greifeinrichtung oder die Greifeinrichtungen heb- und senkbar über dem Maschinentischbereich und/oder dem zusätzlichen Maschinentischbereich angeordnet sind.As far as appropriate gripping devices are present, it is in any case favorable if the feed device, viewed in the transverse direction orthogonal to the transport direction, has a working area and the gripping device (s) of the additional feed device can engage in this working area of the feed device. Accordingly, it is also advantageous if the additional feed device, viewed in the transverse direction orthogonal to the transport direction, has an additional working area and the gripping device (s) of the feed device can engage in this additional working area of the additional feed device. So that the feed devices including gripping devices can also travel over workpieces resting on the respective machine table areas, preferred embodiments of the invention provide, as is known per se, for the gripping device or gripping devices to be raised and lowered above the machine table area and / or the additional machine table area.
Weiters ist es günstig, wenn eine, mehrere oder alle der Greifeinrichtungen in Querrichtung entlang der Vorschubeinrichtung verschiebbar gelagert sind. Dieses Verschieben in Querrichtung entlang der Vorschubeinrichtung kann erfolgen, um die Lage der Greifeinrichtung(en) in Querrichtung an die Lage bzw. die Größe des zu transportierenden plattenförmigen und/oder sonstigen Werkstücks anpassen zu können. Diese Verschiebung kann manuell, aber auch von einem Motor erfolgen.Furthermore, it is favorable if one, several or all of the gripping devices are mounted displaceably in the transverse direction along the feed device. This displacement in the transverse direction along the feed device can take place in order to be able to adapt the position of the gripping device (s) in the transverse direction to the position or the size of the plate-shaped and / or other workpiece to be transported. This shift can be done manually, but also by a motor.
Sogenannte Druckbalken, welche das zu zersägende Werkstück im Bereich der Schnittlinie auf die Oberfläche des Maschinentischbereiches andrücken, sind beim Stand der Technik an sich bekannt. Sie dienen dazu, einen möglichst sauberen und vibrationsarmen Sägevorgang bzw. Schnitt entlang der Schnittlinie durchführen zu können. In diesem Zusammenhang sei darauf hingewiesen, dass günstigerweise auch erfindungsgemäße Sägemaschinen zumindest einen Druckbalken zum Andrücken zumindest eines plattenförmigen und/oder sonstigen Werkstücks auf den Maschinentischbereich und/oder den zusätzlichen Maschinentischbereich bei der Schnittlinie aufweist.So-called pressure bars, which press the workpiece to be sawn in the area of the cutting line on the surface of the machine table area, are known per se in the prior art. They serve to carry out a clean as possible and low-vibration sawing or cutting along the cutting line. In this context, it should be noted that favorably sawing machines according to the invention at least one pressure bar for Having pressing at least one plate-shaped and / or other workpiece on the machine table area and / or the additional machine table area at the cutting line.
Wenn die vertikale Ausdehnung, also die Dicke des plattenförmigen Werkstücks und des gleichzeitig zu zersägenden sonstigen Werkstücks unterschiedlich sind, kann es günstig sein, wenn der Druckbalken gleichzeitig in verschiedenen Bereichen entlang der Schnittlinie unterschiedlich weit absenkbar ist. Dies kann helfen, um während eines einzigen Schnitt- bzw. Sägevorgangs ein dickeres sonstiges Werkstück und ein dünneres plattenförmiges Werkstück oder ein dickeres plattenförmiges Werkstück und ein dünneres sonstiges Werkstück in gleicher Weise fest gegen die Oberfläche des jeweiligen Maschinentischbereichs drücken zu können.If the vertical extent, ie the thickness of the plate-shaped workpiece and the other workpiece to be simultaneously sawn, are different, it may be favorable if the pressure bar can be lowered at different depths along the cutting line at the same time. This may help to be able to press firmly against the surface of the respective machine table area in a similar manner during a single cutting or sawing a thicker other workpiece and a thinner plate-shaped workpiece or a thicker plate-shaped workpiece and a thinner other workpiece.
Bei der Sägeeinrichtung kann es sich, wie an sich bekannt, um eine heb- und senkbar ausgeführte Unterflurkreissäge handeln. Diese ist bevorzugt in einem Sägewagen entlang der Schnittlinie verfahrbar. Z.B. um den Schnitt entlang der Schnittlinie durchführen zu können.As is well known, the sawing device may be a raised-bottomed lowerable circular saw. This is preferably movable in a saw carriage along the cutting line. For example, to make the cut along the cutting line.
Grundsätzlich ist es möglich, die zu zersägenden oder bereits zersägten Werkstücke per Hand für einen weiteren Sägevorgang zu drehen. Beim Stand der Technik sind aber auch Dreheinrichtungen in Form von sogenannten Drehtischen bekannt. Auch diese können günstigerweise bei erfindungsgemäßen Sägemaschinen eingesetzt werden. So kann vorgesehen sein, dass die Sägemaschine, vorzugsweise in einem Bereich in Transportrichtung gesehen hinter der Schnittlinie, eine Dreheinrichtung zum Drehen des plattenförmigen und/oder sonstigen Werkstücks, vorzugsweise um eine vertikale Achse, aufweist. Natürlich können entsprechende Dreheinrichtungen auch in Transportrichtung gesehen im Bereich vor der Schnittlinie angeordnet sein.In principle, it is possible to turn the workpieces to be sawn or already sawn by hand for another sawing operation. In the prior art but also rotating devices in the form of so-called rotary tables are known. These can also be conveniently used in sawing machines according to the invention. Thus, it can be provided that the sawing machine, preferably seen in a region in the transport direction behind the cutting line, a rotating device for rotating the plate-shaped and / or other workpiece, preferably about a vertical axis having. Of course, corresponding rotating devices can also be arranged in the region in front of the cutting line, as seen in the transport direction.
Für die Zuführung der plattenförmigen und/oder sonstigen Werkstücke zur Sägemaschine bzw. deren Maschinentischbereiche gibt es verschiedene Möglichkeiten. Z.B. kann vorgesehen sein, dass das plattenförmige Werkstück, in Transportrichtung gesehen, von einem Bereich hinter der Schnittlinie aus in Richtung entgegen der Transportrichtung über die Schnittlinie hinweg und/oder, in Transportrichtung gesehen, im Bereich vor der Schnittlinie von zumindest einer Seite her in einer Querrichtung orthogonal zur Transportrichtung zuführbar ist. Weiters kann vorgesehen sein, dass das sonstige Werkstück, in Transportrichtung gesehen, von einem Bereich hinter der Schnittlinie aus in Richtung entgegen der Transportrichtung über die Schnittlinie hinweg und/oder, in Transportrichtung gesehen, im Bereich vor der Schnittlinie aus einem Bereich vor der zusätzlichen Vorschubeinrichtung der zusätzlichen Vorschubeinrichtung zuführbar ist. Bevorzugte Ausgestaltungsformen der Erfindung sehen auch vor, dass das sonstige Werkstück, in Transportrichtung gesehen, im Bereich vor der Schnittlinie, vorzugsweise im Bereich vor dem Maschinentischbereich, von zumindest einer Seite her in einer Querrichtung orthogonal zur Transportrichtung der zusätzlichen Vorschubeinrichtung zuführbar ist.There are various possibilities for feeding the plate-shaped and / or other workpieces to the sawing machine or their machine table areas. For example, it can be provided that the plate-shaped workpiece, viewed in the transport direction, from an area behind the cutting line in the direction opposite to the transport direction over the cutting line and / or, seen in the transport direction, in the region in front of the cutting line from at least one side in a transverse direction orthogonal to the transport direction can be fed. Furthermore, it can be provided that the other workpiece, viewed in the transport direction, from an area behind the cutting line in the direction opposite to the transport direction over the cutting line and / or, seen in the transport direction, in the area in front of the cutting line from a region in front of the additional feed device the additional feed device can be fed. Preferred embodiments of the invention also provide that the other workpiece, viewed in the transport direction, in the region in front of the cutting line, preferably in the area in front of the machine table area, from at least one side in a transverse direction orthogonal to the transport direction of the additional feed device can be fed.

Zunächst wird nun anhand der schematisierten Draufsicht gemäß
Die Sägemaschine 1 des ersten Ausführungsbeispiels weist einen Maschinentischbereich 4 und eine diesem zugeordnete Vorschubeinrichtung 5 auf. Die Vorschubeinrichtung 5 kann mit ihren Greifeinrichtungen 15, hier strichliert in verschiedenen möglichen Lagen dargestellte, plattenförmige Werkstücke 2, welche im Maschinentischbereich 4 auf dem Maschinentisch 29 aufliegen, greifen und in Transportrichtung 6 der Schnittlinie 3 zuführen. Nachdem erfindungsgemäß auch ein zusätzlicher Maschinentischbereich 7 mit einer zusätzlichen Vorschubeinrichtung 8 für sonstige, insbesondere stangen- bzw. rohrförmige, Werkstücke 9 vorhanden ist, können der für die plattenförmigen Werkstücke 2 vorgesehene Maschinentischbereich 4 und die diesem zugeordnete Vorschubeinrichtung 5 auch als erster Maschinentischbereich und als erste Vorschubeinrichtung bezeichnet werden. Der Maschinentischbereich bzw. erste Maschinentischbereich 4 ist in seiner Größe durch die maximale Vorschublänge 11 und den Arbeitsbereich bzw. ersten Arbeitsbereich 13 definiert. In diesem Maschinentischbereich 4 können die plattenförmigen Werkstücke 2 von der Vorschubeinrichtung 5 bewegt und auch festgehalten werden. Die Größe des Maschinentischbereichs 4 ist in der Regel auf die größte Kantenlänge der zu bearbeitenden plattenförmigen Werkstücke 2 ausgerichtet. Wie eingangs erläutert, können die plattenförmigen Werkstücke 2 in Form von Einzelplatten aber auch von Plattenstapeln verarbeitet werden. In den
Der zusätzliche Maschinentischbereich 7, auf dem die sonstigen Werkstücke 9 von der zusätzlichen Vorschubeinrichtung 8 bewegt werden können, weist erfindungsgemäß eine größere maximale Vorschublänge 10 auf. In

Der in Transportrichtung 6 gesehen hinter der Schnittlinie 3 angeordnete Bereich 17 ist ebenso eingezeichnet, wie der in Transportrichtung 6 gesehen vor der Schnittlinie 3 angeordnete Bereich 18. Weiters eingezeichnet ist auch der, in Transportrichtung 6 gesehen, vor der zusätzlichen Vorschubeinrichtung 8 angeordnete Bereich 21, wie auch der in Transportrichtung 6 gesehen vor dem Maschinentischbereich 4 angeordnete Bereich 22. Die Transportrichtung 6 ist sowohl vor als auch hinter der Schnittlinie 3 eingezeichnet.The
Im Betrieb der erfindungsgemäßen Sägemaschine 1 können plattenförmige Werkstücke 2 im Maschinentischbereich 4 von der Vorschubeinrichtung 5 in Transportrichtung 6 der Schnittlinie 3 zugeführt und dort zersägt werden. Anschließend erfolgt der Weitertransport in Transportrichtung 6 z.B. auf die Ablagetische 24. Die sonstigen, insbesondere längeren Werkstücke 9, z.B. in Form von Stangen oder Rohren, Aluprofilen und dergleichen können im zusätzlichen Maschinentischbereich 7 in Transportrichtung 6 von der zusätzlichen Vorschubeinrichtung 8 ebenfalls der Schnittlinie 3 zugeführt werden, um dort zersägt und dann entsprechend auf die Ablagetische 24 weitertransportiert zu werden. Diese Sägevorgänge an plattenförmigen Werkstücken 2 und sonstigen Werkstücken 9 können getrennt voneinander stattfinden. Es ist aber genauso gut möglich, dass, wenn bei den plattenförmigen Werkstücken 2 im Maschinentischbereich 4 ein entsprechender Platz freigelassen ist, gleichzeitig plattenförmige Werkstücke 2 und sonstige Werkstücke 9 der Schnittlinie 3 zugeführt werden, um dann gleichzeitig zersägt zu werden.During operation of the sawing machine 1 according to the invention, plate-shaped
Um einen qualitativ möglichst hochwertigen vibrationsarmen Schnitt bzw. Sägevorgang durchführen zu können, ist im gezeigten Ausführungsbeispiel der Erfindung ein Druckbalken 16 vorgesehen, welcher an den Seitenständern 28 so gelagert ist, dass der Druckbalken 16 vor dem Schnitt bzw. Sägevorgang auf die Maschinentischbereiche 4 und 7 abgesenkt werden kann und das jeweilige Werkstück 2 und/oder 9 im Bereich der Schnittlinie 3 auf den jeweiligen Maschinentischbereich 4 und/oder 7 zu drücken. Ist der Schnitt bzw. Sägevorgang erfolgt, so wird der Druckbalken 16 entlang der Seitenständer 28 wieder angehoben, sodass ein Weitertransport der Werkstücke 2 und 9 in Transportrichtung 6 möglich ist. Solche Druckbalken 16 sind beim Stand der Technik an sich bekannt und müssen hier nicht zwingend weiter erläutert werden. Wie eingangs bereits darauf hingewiesen wurde, weisen allerdings bevorzugte Ausgestaltungsformen solcher Druckbalken 16 entlang der Schnittlinie 3 unterschiedliche Abschnitte auf, die einzeln bzw. getrennt voneinander und unterschiedlich weit in Vertikalrichtung, also zum plattenförmigen Werkstück 2 bzw. 9 hin und von diesem wieder weg bewegt werden können. Dies ist günstig, wenn ein plattenförmiges Werkstück 2 und ein sonstiges Werkstück 9, welche eine unterschiedliche Dicke bzw. Vertikalerstreckung aufweisen, gleichzeitig zersägt werden sollen. Günstigerweise erstreckt sich somit in Horizontalrichtung, also entlang der Schnittlinie 3, ein erster solcher Bereich des Druckbalkens 16 im zusätzlichen Arbeitsbereich 14 und ein zweiter solcher Teil des Druckbalkens 16 im nicht vom zusätzlichen Arbeitsbereich 14 abgedeckten restlichen Teil des Arbeitsbereichs 13.In order to carry out a qualitative high-quality low-vibration cutting or sawing, in the illustrated embodiment of the invention, a
Als hier nicht im Detail dargestellte Sägeeinrichtung kann z.B. eine beim Stand der Technik bekannte heb- und senkbare Unterflurkreissäge verwendet werden. Diese kann für den Sägevorgang durch die Schnittlinie 2 hindurch über das Niveau der Oberfläche der Maschinentischbereiche 4 und 7 angehoben werden und für Rücktransporte unter diese Ebene abgesenkt werden. Natürlich können im Zuge der Erfindung auch andere Sägeeinrichtungen realisiert werden. Im gezeigten Ausführungsbeispiel ist die Sägeeinrichtung jedenfalls im in

Um die plattenförmigen Werkstücke 2 für die Ausrichtung und den Sägevorgang dem Maschinentischbereich 4 zuzuführen, kann vorgesehen sein, dass die zu zersägenden plattenförmigen Werkstücke 2 im Bereich 17 hinter der Schnittlinie 3 hier auf den Ablagetisch 24 aufgelegt, dort von den Greifern 15 der Vorschubeinrichtung 5 gegriffen und über die Schnittlinie 3 hinweg entgegen der Transportrichtung 6 in den Maschinentischbereich 4 eingezogen und dort positioniert werden. Genauso gut ist es, wie in
