Description

Die Erfindung betrifft eine Sägeeinrichtung zum Aufteilen plattenförmiger Werkstücke mit den Merkmalen des Oberbegriffes von Patentanspruch 1.The invention relates to a sawing device for splitting plate-shaped workpieces with the features of the preamble of claim 1.

Derartige Sägeeinrichtungen sind aus der WO 02/26452 A1 bekannt. Mit ihrer Hilfe können plattenförmige Werkstücke, insbesondere Holz- oder Kunststoffplatten, aufgeteilt werden, wobei die Sägeschnitte sowohl parallel oder senkrecht zu einer Längskante der Werkstücke als auch schräg zur Längskante ausgeführt werden können. Die Vornahme des Sägeschnittes erfolgt mittels einer Sägeeinheit, die an einem Sägewagen gehalten ist, welcher zur Vornahme des Sägeschnittes entlang einer Sägelinie verfahrbar ist. Die Werkstücke können mittels einer Vorschubvorrichtung in Höhe der Sägelinie positioniert werden. Hierzu umfaßt die Vorschubvorrichtung zumindest eine Klemmvorrichtung zum Erfassen der Werkstücke, so daß diese reproduzierbar positioniert werden können. Während der Vornahme des Sägeschnittes werden die Werkstücke mittels der Niederhaltevorrichtung zuverlässig am Auflagetisch gehalten. Als Niederhaltevorrichtung kann beispielsweise ein in vertikaler Richtung verstellbar gehaltener Druckbalken zum Einsatz kommen.Such sawing devices are known from WO 02/26452 A1. With their help, plate-shaped workpieces, in particular wood or plastic plates can be divided, wherein the saw cuts can be performed both parallel or perpendicular to a longitudinal edge of the workpieces as well as obliquely to the longitudinal edge. The saw cut is carried out by means of a saw unit, which is held on a saw carriage, which can be moved along a saw line to make the saw cut. The workpieces can be positioned by means of a feed device at the level of the saw line. For this purpose, the feed device comprises at least one clamping device for detecting the workpieces, so that they can be positioned reproducibly. During the performance of the saw cut, the workpieces are reliably held on the support table by means of the hold-down device. As a hold-down device, for example, a vertically adjustable held pressure bar can be used.

Zur Vornahme schräg zu einer Längskante verlaufender Sägeschnitte sind bei der aus der WO 02/26452 A1 bekannten Sägeeinrichtung mehrere Anschlagelemente vorgesehen, an die die aufzuteilenden Werkstücke angelegt werden können. Ein erstes Anschlagelement ist in Form einer Anschlagleiste an der Vorschubvorrichtung angeordnet. Ein zweites Anschlagelement ist unverschiebbar am Auflagetisch gehalten, und ein drittes Anschlagelement ist an einer plattenförmigen Auflagevorrichtung angeordnet, die parallel zur Sägelinie verstellbar am Maschinengestell gelagert ist. Durch Verstellen der plattenförmigen Auflagevorrichtung kann das dritte Anschlagelement relativ zum zweiten Anschlagelement bewegt werden, so daß an die beiden Anschlagelemente anzulegende Werkstücke relativ zur Sägelinie unterschiedliche Orientierungen einnehmen können. Ein manuelles Einrichten der Werkstücke bezüglich der Sägelinie kann dadurch entfallen. Der Einsatz einer plattenförmigen Auflagevorrichtung, die verstellbar am Maschinengestell gehalten ist, kann allerdings eine Störungsempfindlichkeit der bekannten Sägeeinrichtung zur Folge haben und ist mit nicht unbeträchtlichen Herstellungskosten verbunden.To carry out obliquely to a longitudinal edge extending saw cuts several stop elements are provided in the sawing device known from WO 02/26452 A1, to which the workpieces to be split can be created. A first stop element is arranged in the form of a stop bar on the feed device. A second stop element is held immovably on the support table, and a third stop element is arranged on a plate-shaped support device which is parallel to the saw line is mounted adjustable on the machine frame. By adjusting the plate-shaped support device, the third stop element can be moved relative to the second stop element, so that to be applied to the two stop elements workpieces relative to the saw line can take different orientations. A manual setup of the workpieces with respect to the saw line can be omitted. The use of a plate-shaped support device which is adjustably held on the machine frame, however, can cause a disturbance sensitivity of the known sawing device and is associated with not inconsiderable manufacturing costs.

Aufgabe der vorliegenden Erfindung ist es, eine Sägeeinrichtung der eingangs genannten Art derart weiterzubilden, daß sie einen konstruktiv einfacheren und störungsunempfindlicheren Aufbau aufweist.Object of the present invention is to provide a sawing device of the type mentioned in such a way that it has a structurally simpler and störungsunempfindlicheren structure.

Diese Aufgabe wird bei einer Sägeeinrichtung der gattungsgemäßen Art erfindungsgemäß dadurch gelöst, daß das erste Anschlagelement einen Anschlagwinkel umfasst mit zwei winklig zueinander ausgerichteten Anschlagschenkeln, die einen Eckbereich der Werkstücke zwischen sich aufnehmen, wobei der Anschlagwinkel schwenkbar an der Vorschubvorrichtung gehalten und die Schwenkachse des Anschlagwinkels senkrecht zur Vorschubrichtung und senkrecht zur Sägelinie ausgerichtet ist, und daß am Sägewagen ein zweites Anschlagelement positioniert ist, an das die Werkstücke seitlich anlegbar sind.This object is achieved in a sawing device of the generic type according to the invention that the first stop element comprises a stop angle with two angularly aligned stop legs, which receive a corner region of the workpieces between them, the stop angle pivotally held on the feed device and the pivot axis of the stop angle perpendicular is aligned to the feed direction and perpendicular to the saw line, and that on the saw carriage, a second stop element is positioned, to which the workpieces are applied laterally.

Mittels der ersten und zweiten Anschlagelemente kann den aufzuteilenden Werkstücken eine eindeutige Ausrichtung bezüglich der Sägelinie vorgegeben werden, wobei der zusätzliche Einsatz einer verstellbaren plattenförmigen Auflagevorrichtung entfallen kann. Um sicherzustellen, daß die ersten und zweiten Anschlagelemente je nach gewünschtem Sägeschnitt die erforderliche Positionierung relativ zueinander einnehmen können, ist erfindungsgemäß vorgesehen, daß das zweite Anschlagelement am Sägewagen positioniert ist. Der Sägewagen ist entlang der Sägelinie reproduzierbar verfahrbar am Maschinengestell gelagert, und diese Verfahrbarkeit wird gemäß der vorliegenden Erfindung auch zur Ausrichtung des zweiten Anschlagelementes herangezogen. Somit kann das zweite Anschlagelement vorgebbar jede beliebige Stellung entlang der Sägelinie einnehmen.By means of the first and second stop elements, the workpieces to be split can be given a clear alignment with respect to the saw line, with the additional use of an adjustable plate-shaped Pad device can be omitted. To ensure that the first and second stop elements can take the required positioning relative to each other depending on the desired saw cut, the invention provides that the second stop element is positioned on the saw carriage. The saw carriage is mounted reproducibly movable on the machine frame along the saw line, and this movability is also used according to the present invention for the alignment of the second stop element. Thus, the second stop element can predeterminarily take any position along the saw line.

Das erste Anschlagelement ist an der Vorschubvorrichtung angeordnet, die reproduzierbar quer zur Sägelinie hin- und herbewegbar ist. Damit kann das erste Anschlagelement bezogen auf die Vorschubrichtung in vorgebbarer Weise jede beliebige Position relativ zum zweiten Anschlagelement einnehmen. Aufgrund der Verfahrbarkeit der ersten und zweiten Anschlagelemente können die aufzuteilenden Werkstücke in beliebiger Orientierung in Bezug auf die Sägelinie ausgerichtet werden, indem sie an die Anschlagelemente angelegt werden, die entsprechend des gewünschten Sägeschnittes positionierbar sind.The first stop element is arranged on the feed device, which is reproducibly back and forth transversely to the saw line. Thus, the first stop element based on the feed direction in a predeterminable manner assume any position relative to the second stop element. Due to the mobility of the first and second stop members, the workpieces to be split can be oriented in any orientation with respect to the saw line by being applied to the stop members, which are positionable according to the desired saw cut.

Erfindungsgemäß umfaßt das erste Anschlagelement einen Anschlagwinkel mit zwei winklig zueinander ausgerichteten Anschlagschenkeln, die einen Eckbereich der Werkstücke zwischen sich aufnehmen, wobei der Anschlagwinkel schwenkbar an der Vorschubvorrichtung gehalten und die Schwenkachse des Anschlagwinkels senkrecht zur Vorschubrichtung und senkrecht zur Sägelinie ausgerichtet ist. Durch den Anschlagwinkel kann dem aufzuteilenden Werkstück eine eindeutige Ausrichtung bezogen auf das erste Anschlagelement vorgegeben werden, indem das Werkstück mit einem der Sägelinie abgewandten Eckbereich an die beiden Anschlagschenkel angelegt wird. Der Anschlagwinkel ist senkrecht zur Vorschubrichtung und senkrecht zur Sägelinie verschwenkbar und kann damit unterschiedliche Orientierungen bezogen auf die Sägelinie annehmen.According to the invention the first stop element comprises a stop angle with two angularly aligned stop legs, which receive a corner portion of the workpieces between them, wherein the stop angle is pivotally supported on the feed device and the pivot axis of the stop angle is aligned perpendicular to the feed direction and perpendicular to the saw line. Due to the stop angle, the workpiece to be split can be given an unambiguous orientation relative to the first stop element by the workpiece facing away from the saw line Corner is applied to the two stop legs. The stop angle is perpendicular to the feed direction and perpendicular to the saw line pivoted and can thus assume different orientations with respect to the saw line.

Weitere vorteilhafte Ausführungsformen sind den abhängigen Ansprüchen 2 bis 14 zu entnehmen.Further advantageous embodiments can be found in the dependent claims 2 to 14.

Das zweite Anschlagelement kann beispielsweise als Anschlagbolzen ausgestaltet sein, der zur Ausrichtung eines aufzuteilenden Werkstückes in eine korrespondierende Aufnahme des Sägewagens eingesteckt werden kann. Nach erfolgter Ausrichtung des Werkstückes kann dann das zweite Anschlagelement wieder vom Sägewagen entfernt werden, um anschließend das Werkstück mittels der Niederhaltevorrichtung zuverlässig am Auflagetisch zu halten und den Sägewagen zur Vornahme des Sägeschnittes entlang der Sägelinie zu verfahren.The second stop element may for example be designed as a stop pin, which can be inserted to align a workpiece to be split into a corresponding receptacle of the saw carriage. After alignment of the workpiece then the second stop element can be removed again from the saw carriage to then the workpiece To hold reliably by means of the hold-down device on the support table and to move the saw carriage to make the saw cut along the saw line.

Alternativ kann vorgesehen sein, daß das zweite Anschlagelement zwischen einer Anschlagstellung, in der es über eine Tischebene des Auflagetisches übersteht, und einer Freigabestellung, in der es unterhalb der Tischebene positioniert ist, bewegbar am Sägewagen gehalten ist. Das zweite Anschlagelement kann somit in vertikaler Richtung hin- und herbewegt werden. Zur Vornahme eines schräg verlaufenden Sägeschnittes wird der Sägewagen entlang der Sägelinie auf eine gewünschte Position verfahren und das zweite Anschlagelement in seine Anschlagstellung bewegt, so daß die aufzuteilenden Werkstücke seitlich daran angelegt werden können. Anschließend kann die Niederhaltevorrichtung betätigt werden, um die Werkstücke zuverlässig zu halten, so daß dann das zweite Anschlagelement in seine Freigabestellung bewegt werden kann, ohne daß die Gefahr besteht, daß die Orientierung der Werkstücke verändert wird. Während der Vornahme des Sägeschnittes ist somit das zweite Anschlagelement am Sägewagen gehalten, allerdings nimmt es eine Position unterhalb der Tischebene des Auflagetisches ein, so daß durch das zweite Anschlagelement das Aufteilen der Werkstücke nicht beeinträchtigt wird.Alternatively it can be provided that the second stop element between a stop position in which it projects beyond a table level of the support table, and a release position in which it is positioned below the table level, is movably held on the saw carriage. The second stop element can thus be reciprocated in the vertical direction. To make an oblique saw cut the saw carriage is moved along the saw line to a desired position and moves the second stop element in its stop position, so that the workpieces to be split can be applied laterally thereto. Subsequently, the hold-down device can be actuated to hold the workpieces reliably, so that then the second stop element can be moved to its release position, without the risk that the orientation of the workpieces is changed. During the operation of the saw cut, the second stop element is thus held on the saw carriage, but it assumes a position below the table level of the support table, so that the splitting of the workpieces is not affected by the second stop element.

Es kann vorgesehen sein, daß die vertikale Bewegung des zweiten Anschlagelementes manuell erfolgt, beispielsweise mittels einer Handkurbel. Günstig ist es allerdings, wenn dem zweiten Anschlagelement eine motorische Antriebseinrichtung zugeordnet ist zum Bewegen des zweiten Anschlagelementes. Als Antriebseinrichtung kann beispielsweise ein Elektro- oder Druckluftmotor zum Einsatz kommen.It can be provided that the vertical movement of the second stop element is done manually, for example by means of a hand crank. It is favorable, however, if the second stop element is associated with a motor drive device for moving the second stop element. As a drive device, for example, an electric or pneumatic motor can be used.

Bei einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Sägeeinrichtung umfaßt die Antriebseinrichtung ein pneumatisch oder hydraulisch betätigbares Kolben-Zylinder-Aggregat. Dies gibt die Möglichkeit, daß zweite Anschlagelement beispielsweise als Anschlagbolzen auszugestalten, der an einer Kolbenstange gehalten ist, die durch Beaufschlagen eines zugeordneten Zylinders mit einem Druckmedium, beispielsweise mit Druckluft, in vertikaler Richtung hin- und bewegbar ist.In a particularly preferred embodiment of the sawing device according to the invention, the drive means comprises a pneumatically or hydraulically actuated piston-cylinder unit. This gives the possibility that second stop element, for example, as a stop pin to design, which is held on a piston rod, the back by applying an associated cylinder with a pressure medium, for example, with compressed air, in the vertical direction and is movable.

Wie eingangs erläutert, können die aufzuteilenden Werkstücke mittels der Vorschubvorrichtung relativ zur Sägelinie positioniert werden. Hierzu umfaßt die Vorschubvorrichtung mindestens eine Klemmvorrichtung, mit deren Hilfe die aufzuteilenden Werkstücke erfaßt werden können. Bei einer bevorzugten Ausführungsform ist vorgesehen, daß die Klemmvorrichtungen jeweils einem ersten Anschlagelement zugeordnet sind zum Erfassen der Werkstücke im Bereich der ersten Anschlagelemente. Dadurch wird sichergestellt, daß die Werkstücke zuverlässig am ersten Anschlagelement festlegbar sind. Dies gibt die Möglichkeit, zur Vornahme eines schräg verlaufenden Sägeschnittes die Vorschubvorrichtung zunächst in eine vordere, der Sägelinie benachbarte Position zu bewegen, um in dieser Position die aufzuteilenden Werkstücke an das erste Anschlagelement anzulegen. Die Werkstücke können dann von der zugeordneten Klemmvorrichtung erfaßt werden, so daß sie unverschiebbar am ersten Anschlagelement gehalten sind. Anschließend kann die Vorschubvorrichtung entsprechend der Länge der aufzuteilenden Werkstücke nach hinten in eine zur Sägelinie beabstandete Position verfahren werden, wobei die Werkstücke nach hinten verschoben werden. Gleichzeitig lassen sich die Werkstücke seitlich an das am Sägewagen angeordnete zweite Anschlagelement anlegen, so daß sie bezogen auf die Sägelinie die gewünschte Orientierung einnehmen.As explained above, the workpieces to be split can be positioned by means of the feed device relative to the saw line. For this purpose, the feed device comprises at least one clamping device by means of which the workpieces to be split can be detected. In a preferred embodiment it is provided that the clamping devices are each assigned to a first stop element for detecting the workpieces in the region of the first stop elements. This ensures that the workpieces are reliably fixed to the first stop element. This makes it possible to carry out an oblique saw cut the feed device initially in a front, the saw line adjacent position to apply in this position, the workpieces to be split to the first stop element. The workpieces can then be detected by the associated clamping device, so that they are held immovably on the first stop element. Subsequently, the feed device can be moved according to the length of the workpieces to be split backwards in a position spaced apart from the sawing line, wherein the workpieces are moved backwards. At the same time, the workpieces can be attached laterally Apply the arranged on the saw carriage second stop element, so that they occupy the desired orientation relative to the saw line.

Besonders vorteilhaft ist es, wenn die jeweils einem ersten Anschlagelement zugeordneten Klemmvorrichtungen zusammen mit dem jeweiligen ersten Anschlagelement um eine Schwenkachse verschwenkbar an der Vorschubvorrichtung gehalten sind, wobei die Schwenkachse senkrecht zur Vorschubvorrichtung und senkrecht zur Sägelinie ausgerichtet ist. Durch die Verschwenkbarkeit der ersten Anschlagelemente und der zugeordneten Klemmvorrichtungen wird die Ausrichtung der aufzuteilenden Werkstücke vereinfacht.It is particularly advantageous if the clamping devices respectively assigned to a first stop element are held together with the respective first stop element so as to be pivotable about a pivot axis on the feed device, wherein the pivot axis is aligned perpendicular to the feed device and perpendicular to the saw line. Due to the pivotability of the first stop elements and the associated clamping devices, the alignment of the workpieces to be split is simplified.

Die Klemmvorrichtungen sind vorzugsweise zangenartig ausgestaltet und umfassen mindestens eine Spannbacke, die um eine senkrecht zur Schwenkachse der Klemmvorrichtungen ausgerichtete Drehachse drehbar gehalten ist. Die Spannbacke ist bevorzugt mit einem Spannzylinder gekoppelt, der mit einem Druckmedium, beispielsweise mit Druckluft, beaufschlagbar ist zum Erfassen der aufzuteilenden Werkstücke.The clamping devices are preferably configured like pliers and comprise at least one clamping jaw, which is rotatably supported about a rotational axis aligned perpendicular to the pivot axis of the clamping devices. The clamping jaw is preferably coupled to a clamping cylinder, which can be acted upon by a pressure medium, for example compressed air, for detecting the workpieces to be split up.

Es kann beispielsweise vorgesehen sein, daß die Spannbacke als zweiarmiger Hebel ausgestaltet ist, der mit einem ersten Ende an ein Werkstück anlegbar ist und dessen zweites Ende mit dem Spannzylinder gekoppelt ist.It can be provided, for example, that the clamping jaw is designed as a two-armed lever, which can be applied with a first end to a workpiece and the second end is coupled to the clamping cylinder.

Das Anlegen der aufzuteilenden Werkstücke am ersten Anschlagelement wird bei einer bevorzugten Ausführungsform dadurch vereinfacht, daß dem ersten Anschlagelement ein vorzugsweise plattenförmig ausgestaltetes Stützglied zugeordnet ist zum Abstützen des am ersten Anschlagelement anliegenden Bereiches der Werkstücke, wobei die Werkstücke zwischen das Stützglied und die zugeordnete Klemmvorrichtung einspannbar sind. Das Stützglied dient somit zum einen der Abstützung der aufzuteilenden Werkstücke, zum anderen bildet das Stützglied ein Widerlager für die Klemmvorrichtung, so daß die Werkstükke im Bereich des ersten Anschlagelementes zwischen die Klemmvorrichtung und das Stützglied eingespannt werden können.The application of the workpieces to be split on the first stop element is simplified in a preferred embodiment in that the first stop element is assigned a preferably plate-shaped ausgestaltetes support member for supporting the voltage applied to the first stop element region of the workpieces, wherein the workpieces between the support member and the associated clamping device can be clamped. The support member thus serves, on the one hand, to support the workpieces to be split up; on the other hand, the support member forms an abutment for the clamping device, so that the workpieces can be clamped in the area of the first stop element between the clamping device and the support member.

Von Vorteil ist es, wenn das Stützglied einen Drehteller umfaßt, an dem das erste Anschlagelement sowie die zugeordnete Klemmvorrichtung gehalten sind, wobei der Drehteller um eine senkrecht zur Vorschubrichtung und senkrecht zur Sägelinie ausgerichtete Drehachse drehbar an der Vorschubvorrichtung gehalten ist. Das erste Anschlagelement und die Klemmvorrichtung können somit durch Drehen des Drehtellers gemeinsam ausgerichtet werden.It is advantageous if the support member comprises a turntable on which the first stop element and the associated clamping device are held, wherein the turntable is held about a perpendicular to the feed direction and perpendicular to the saw axis aligned rotation axis of the feed device. The first stop element and the clamping device can thus be aligned together by turning the turntable.

Günstig ist es, wenn zumindest ein Anschlagschenkel des ersten Anschlagelementes federnd gehalten ist. Dies gibt die Möglichkeit, die beiden Anschlagschwenkel spitzwinklig zueinander auszurichten, so daß auch spitzwinklig ausgestaltete Eckbereiche der aufzuteilenden Werkstücke reproduzierbar an das erste Anschlagelement anlegbar sind, wobei die Anschlagschenkel aufgrund ihrer federnden Halterung derart verschwenkbar sind, daß sie in einander abgewandte Richtungen verschwenkt werden können zur Aufnahme beispielsweise rechtwinklig ausgerichteter Eckbereiche der Werkstücke.It is advantageous if at least one stop leg of the first stop element is resiliently held. This makes it possible to align the two Anschlagschwenkel acute angle to each other, so that even acute-angled corner portions of the workpieces to be split are reproducibly applied to the first stop element, the stop legs are so pivotable due to their resilient support that they can be pivoted in opposite directions to Recording, for example, rectangular aligned corner areas of the workpieces.

Die federnde Halterung der Anschlagschenkel kann mittels eines federnden Elementes, beispielsweise mittels einer Blattfeder erfolgen.The resilient mounting of the stop leg can be done by means of a resilient element, for example by means of a leaf spring.

Vorzugsweise erfaßt die dem ersten Anschlagelement zugeordnete Klemmvorrichtung die Werkstücke im Bereich zwischen den beiden Anschlagschenkeln.Preferably, the clamping device associated with the first stop element detects the workpieces in the area between the two stop legs.

Zur Vereinfachung der Handhabung ist bei einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Sägeeinrichtung vorgesehen, daß die Sägeeinrichtung eine Steuervorrichtung umfaßt mit einem Eingabeelement zur Eingabe der Abmessung der aufzuteilenden Werkstücke sowie des Winkels, den der Sägeschnitt bezogen auf eine Kante der Werkstücke einnehmen soll, und mit einer Recheneinheit zur Berechnung von Positionsdaten für die ersten und zweiten Anschlagelemente entsprechend den eingegebenen Daten zur Vornahme des gewünschten Sägeschnittes und daß die ersten und zweiten Anschlagelemente den berechneten Positionsdaten entsprechend positionierbar sind. Bei einer derartigen Ausgestaltung der Sägeeinrichtung müssen vom Benutzer lediglich die Abmessung, also die Länge und die Breite der aufzuteilenden Werkstücke, sowie der gewünschte Winkel, den der Sägeschnitt bezogen auf eine Kante der Werkstücke einnehmen soll, eingegeben werden. Die Eingabe kann beispielsweise mittels einer Tastatur erfolgen. Aufgrund der eingegebenen Daten berechnet die Rechnereinheit die erforderlichen Positionen der ersten und zweiten Anschlagelemente, wobei die Position des ersten Anschlagelementes durch dessen Abstand von der Sägelinie vorgegeben wird, während die Position des zweiten Anschlagelementes durch dessen Abstand vom ersten Anschlagelement bezüglich der Sägelinie definiert wird. Die beiden Anschlagelemente werden kann entsprechend der berechneten Positionsdaten positioniert. Durch die so positionierten Anschlagelemente wird die Orientierung der aufzuteilenden Werkstücke eindeutig vorgegeben, die folglich in einfach handhabbarer Weise aufgeteilt werden können.To simplify the handling of the sawing device according to the invention is provided in a particularly preferred embodiment, that the sawing means comprises a control device with an input element for inputting the dimension of the workpieces to be split and the angle to take the saw cut relative to an edge of the workpieces, and with a Arithmetic unit for calculating position data for the first and second stop elements according to the input data for making the desired saw cut and that the first and second stop elements are positioned according to the calculated position data. With such an embodiment of the sawing device, the user only has to refer to the dimension, that is to say the length and the width of the workpieces to be split, as well as the desired angle which the saw cut relates to on an edge of the workpieces should be entered. The input can be made for example by means of a keyboard. Based on the input data, the computer unit calculates the required positions of the first and second stopper members, the position of the first stopper member being set by the distance from the sawing line, while the position of the second stopper member is defined by the distance from the first stopper member with respect to the sawing line. The two stop elements can be positioned according to the calculated position data. By thus positioned stop elements, the orientation of the workpieces to be split is clearly specified, which can thus be divided into an easily manageable manner.

In vielen Fällen werden zwei plattenförmige Werkstücke derart aufgeteilt, daß sie anschließend unter einem vorgegebenen Winkel aneinander gefügt werden können. Hierzu müssen überstehende Bereiche der Werkstücke durch Vornahme schräg zu den Längskanten der Werkstücke ausgerichteter Sägeschnitte abgetrennt werden. Der hierzu erforderliche Winkel der Sägeschnitte bezogen auf die Längskanten der Werkstücke ist davon abhängig, welchen Winkel die beiden Werkstücke anschließend zueinander einnehmen sollen und welche Breite die jeweiligen Werkstücke aufweisen. Kommen zwei Werkstücke mit gleicher Breite zum Einsatz, die anschließend senkrecht zueinander ausgerichtet werden sollen, so hat der Sägeschnitt unter einem Winkel von 45° zu den Längskanten der Werkstücke zu erfolgen. Sind unterschiedliche Breiten vorgesehen, so ist der Winkel des Sägeschnittes bezogen auf eine Längskante des Werkstückes an die entsprechenden Breiten anzupassen. Zur Vereinfachung der hierfür erforderlichen Berechnungen und Orientierungen ist bei einer vorteilhaften Ausführungsform vorgesehen, daß zum Zusägen von zwei Werkstücken, die im Winkel zueinander zusammengefügt werden sollen, die Längen und Breiten der beiden Werkstücke sowie der Winkel, den die beiden Werkstücke zueinander einnehmen sollen, in die Steuervorrichtung eingebbar sind und daß die Anschlagelemente mittels der Steuervorrichtung den erforderlichen Sägeschnitt entsprechend positionierbar sind. Der Benutzer der Sägeeinrichtung hat somit lediglich die Längen- und Breitenmaße der beiden Werkstücke sowie den Winkel, den die beiden Werkstücke beim Zusammenfügen zueinander einnehmen sollen, einzugeben. Anschließend werden die ersten und zweiten Anschlagelemente mittels der Steuervorrichtung selbsttätig so positioniert, daß die beiden Werkstücke zur Vornahme des jeweiligen Sägeschnittes eine derartige Orientierung relativ zur Sägelinie einnehmen, daß sie anschließend im gewünschten Winkel zueinander zusammengefügt werden können.In many cases, two plate-shaped workpieces are divided so that they can then be joined together at a predetermined angle. For this purpose, projecting areas of the workpieces must be separated by making oblique to the longitudinal edges of the workpieces aligned saw cuts. The required angle of the saw cuts relative to the longitudinal edges of the workpieces is dependent on what angle the two workpieces should then take each other and which width the respective workpieces have. If two workpieces of equal width are used, which are then to be aligned perpendicular to one another, the saw cut must be made at an angle of 45 ° to the longitudinal edges of the workpieces. If different widths are provided, then the angle of the saw cut with respect to a longitudinal edge of the workpiece is to be adapted to the corresponding widths. To simplify the calculations and orientations required for this purpose, it is provided in an advantageous embodiment that for the sawing of two workpieces, which are to be joined at an angle to each other, the lengths and widths of the two workpieces and the angle to which the two workpieces should occupy each other, are entered into the control device and that the stop elements by means of the control device the required saw cut are positioned accordingly. The user of the sawing device thus has to enter only the length and width dimensions of the two workpieces as well as the angle which the two workpieces are to occupy to one another during assembly. Subsequently, the first and second stop members are automatically positioned by means of the control device so that the two workpieces assume such an orientation relative to the saw line to make the respective saw cut that they can then be joined together at the desired angle.

In der Zeichnung ist eine erfindungsgemäße Sägeeinrichtung in Form einer insgesamt mit dem Bezugszeichen 10 belegten Druckbalkensäge schematisch dargestellt. Diese umfaßt ein Maschinengestell 12, das einen Auflagetisch 14 ausbildet mit einem Sägespalt 16. Unterhalb des Sägespaltes 16 ist ein Sägewagen 18 entlang einer durch den Sägespalt 16 vorgegebenen Sägelinie 20 (siehe Figur 2) linear verfahrbar am Maschinengestell 12 gehalten. Zum Verfahren und Positionieren des Sägewagens 18 kommt ein in der Zeichnung nicht dargestellter, an sich bekannter Antriebsmotor zum Einsatz. Der Sägewagen 18 trägt zwei Sägeeinheiten in Form einer Vorritzsäge 22 und einer Kreissäge 24, die jeweils ein an sich bekanntes und deshalb in der Zeichnung nicht dargestelltes Antriebsaggregat sowie ein Sägeblatt 26 bzw. 28 aufweisen, das mittels der zugeordneten Antriebsaggregate zur Vornahme eines Sägeschnittes zu einer Drehbewegung antreibbar ist. Die Sägeeinheiten 22, 24 sind in üblicher Weise in vertikaler Richtung verstellbar am Sägewagen 18 gehalten, so daß die zugeordneten Sägeblätter 26 bzw. 28 in einer oberen Stellung der Sägeeinheiten 22, 24 den Sägespalt 16 durchgreifen zur Vornahme eines Sägeschnittes während sie in einer unteren Stellung der Sägeeinheiten 22, 24 unterhalb des Sägespaltes 16 angeordnet sind.In the drawing, a sawing device according to the invention in the form of a total occupied by the reference numeral 10 pressure beam saw is shown schematically. This includes a machine frame 12 which forms a support table 14 with a sawing gap 16. Below the sawing gap 16, a saw carriage 18 is held linearly displaceable on the machine frame 12 along a sawing line 20 (see FIG. 2) provided by the sawing gap 16. For the method and positioning of the saw carriage 18 is a not shown in the drawing, known per se drive motor is used. The saw carriage 18 carries two sawing units in the form of a scoring saw 22 and a circular saw 24, each having a known per se and therefore not shown in the drawing drive unit and a saw blade 26 and 28, by means of the associated drive units for making a saw cut to a Rotary movement is driven. The sawing units 22, 24 are held in a customary manner vertically adjustable on the saw carriage 18, so that the associated saw blades 26 and 28 in an upper position of the saw units 22, 24 pass through the sawing gap 16 for performing a saw cut while in a lower position the sawing units 22, 24 are arranged below the sawing gap 16.

An einander gegenüberliegenden Stirnseiten trägt das Maschinengestell 12 jeweils einen Druckbalkenturm 30 bzw. 32, der jeweils eine Führungsanordnung 34 bzw. 36 aufnimmt. Mittels der Führungsanordnungen 34, 36 ist an den Druckbalkentürmen 30 und 32 eine Niederhaltevorrichtung in Form eines Druckbalkens 38 in zur Tischebene des Auflagetisches 14 senkrechter Richtung verstellbar gehalten. Der Druckbalken 38 weist in üblicher Weise ein ungefähr C-förmiges Profil auf mit einer dem Sägespalt 16 zugewandten schlitzförmigen Öffnung, in die bei der Vornahme eines Sägeschnittes die verstellbar am Sägewagen 18 gehaltenen Sägeblätter 26 und 28 eintreten können.At opposite end faces, the machine frame 12 carries a respective pressure beam tower 30 and 32, each receiving a guide assembly 34 and 36 respectively. By means of the guide assemblies 34, 36 is at the pressure beam towers 30 and 32, a hold-down device in the form of a Pressure bar 38 held adjustable in the direction perpendicular to the table level of the support table 14 direction. The pressure bar 38 has in the usual way an approximately C-shaped profile with a slit 16 facing slit-shaped opening, in which when making a saw cut the saw blade 26 held adjustable saw blades 26 and 28 can occur.

Die Führungsanordnungen 34 und 36 der beiden Druckbalkentürme 30, 32 umfassen in üblicher und deshalb in der Zeichnung nicht dargestellter Weise druckmittelbeaufschlagbare Zylinder, mittels denen der Druckbalken 38 angehoben und abgesenkt werden kann.The guide assemblies 34 and 36 of the two pressure beam towers 30, 32 include in conventional and therefore not shown in the drawing manner druckmittelbeaufschlagbare cylinder, by means of which the pressure bar 38 can be raised and lowered.

Die Druckbalkensäge 10 weist zwei parallel zueinander und senkrecht zur Sägelinie 20 ausgerichtete Führungsschienen 40, 42 auf, an denen eine Vorschubvorrichtung in Form eines Transportschlittens 44 verschiebbar gehalten ist, wobei der Transportschlitten 44 mittels eines an sich bekannten und deshalb in der Zeichnung nicht dargestellten Antriebes entlang der Führungsschienen 40, 42 in einer durch den Doppelpfeil 46 in Figur 1 veranschaulichten Vorschubrichtung definiert hin- und herbewegbar ist.The pressure beam saw 10 has two parallel to each other and perpendicular to the saw line 20 aligned guide rails 40, 42 on which a feed device in the form of a transport carriage 44 is slidably held, wherein the transport carriage 44 by means of a known per se and therefore not shown in the drawing along drive the guide rails 40, 42 can be reciprocated in a defined by the double arrow 46 in Figure 1 feed direction.

Am Transportschlitten 44 sind mehrere an sich bekannte und deshalb in Figur 2 nur schematisch dargestellte Greifzangen 48 gehalten, mit denen ein plattenförmiges Werkstück, vorzugsweise eine Holzplatte, mit parallel zu den Führungsschienen 40, 42 ausgerichteter Längskante (in der Zeichnung nicht dargestellt) erfaßt und in Vorschubrichtung 46 verschoben werden kann. Die Greifzangen 48 sind in Figur 1 zur Erzielung einer besseren Übersichtlichkeit nicht dargestellt.On the transport carriage 44 are several known per se and therefore only shown schematically in Figure 2 gripper tongs 48, with which a plate-shaped workpiece, preferably a wooden plate, aligned parallel to the guide rails 40, 42 aligned longitudinal edge (not shown in the drawing) and in Feed direction 46 can be moved. The grippers 48 are not shown in Figure 1 to achieve a better clarity.

Zusätzlich zu den Greifzangen 48 trägt der Transportschlitten 44 zwei zueinander beabstandete erste Anschlagelemente 50, 52, die identisch ausgebildet und vergrößert in den Figuren 3 und 4 dargestellt sind.In addition to the gripping tongs 48, the transport carriage 44 carries two spaced-apart first stop elements 50, 52, which are of identical design and enlarged in FIGS. 3 and 4.

Die ersten Anschlagelemente 50 und 52 sind jeweils an einem starr mit dem Transportschlitten 44 verbundenen Ausleger 54 gehalten, an dessem freien Ende ein Drehteller 56 drehbar gelagert ist, wobei die Drehachse 58 des Drehtellers 56 senkrecht zur Vorschubrichtung 46 und senkrecht zur Sägelinie 20 ausgerichtet ist. Am Drehteller 56 ist eine Konsole 60 festgelegt, die ein U-förmiges Profil aufweist und in ihrem dem Drehteller 56 abgewandten Endbereich einen über eine in der Zeichnung nicht dargestellte, an sich bekannte Druckleitung mit Druckluft beaufschlagbaren Spannzylinder 62 aufnimmt, in dem ein Spannkolben (in der Zeichnung nicht dargestellt) verschiebbar gelagert ist. Am Spannkolben ist eine aus dem Spannzylinder 62 austretende Kolbenstange 64 festgelegt, die mit ihrem dem Spannzylinder 62 abgewandten Ende an einem Spannbacken 66 anliegt, der als verschwenkbarer, zweiarmiger Hebel ausgestaltet ist und an einem an der Konsole 60 festgelegten Lagerbock 68 verschwenkbar gehalten ist, wobei die Schwenkachse 70 der Spannbacke 66 senkrecht zur Drehachse 58 des Drehtisches 56 ausgerichtet ist.The first stop elements 50 and 52 are each held on a rigidly connected to the transport carriage 44 boom 54, at whose free end a turntable 56 is rotatably mounted, wherein the axis of rotation 58 of the turntable 56 is oriented perpendicular to the feed direction 46 and perpendicular to the saw line 20. On the turntable 56, a console 60 is fixed, which has a U-shaped profile and facing away from the turntable 56 end portion via a not shown in the drawing, known per se pressure line with compressed air acted upon clamping cylinder 62, in which a clamping piston (in the drawing is not shown) is slidably mounted. On the clamping piston exiting from the clamping cylinder 62 piston rod 64 is fixed, which abuts with its end facing away from the clamping cylinder 62 to a clamping jaw 66, which is designed as a pivotable, two-armed lever and is pivotally mounted on a bracket 60 fixed to the bracket 68, wherein the pivot axis 70 of the clamping jaw 66 is aligned perpendicular to the axis of rotation 58 of the turntable 56.

An ihrem der Kolbenstange 64 abgewandten Ende trägt die Spannbacke 66 eine frei drehbare Stützrolle 72, mit der die Spannbacke 66 auf die Oberseite eines aufzuteilenden Werkstückes 74 aufsetzbar ist. Das Werkstück 74 kann hierbei durch Druckbeaufschlagung des Spannzylinders 62 zwischen die Spannbacke 66 und den Drehteller 56 eingespannt werden.At its end facing away from the piston rod 64, the clamping jaw 66 carries a freely rotatable support roller 72 with which the clamping jaw 66 can be placed on the upper side of a workpiece 74 to be split up. The workpiece 74 can in this case be clamped by pressurizing the clamping cylinder 62 between the clamping jaw 66 and the turntable 56.

Die ersten Anschlagelemente 50 und 52 umfassen zwei Anschlagschenkel 76, 78, die zusammen einen Anschlagwinkel 80 ausbilden und jeweils mittels einer Blattfeder 82 bzw. 84 am Lagerbock 68 gehalten sind. Die beiden Anschlagschenkel 76 und 78 können einen Eckbereich 86 des Werkstückes 74 zwischen sich aufnehmen, wobei sie aufgrund ihrer federnden Halterung elastisch aufgespreizt werden können.The first stop members 50 and 52 comprise two stop legs 76, 78, which together form a stop angle 80 and are each held by a leaf spring 82 and 84 on the bearing block 68. The two stop legs 76 and 78 can accommodate a corner portion 86 of the workpiece 74 between them, where they can be spread elastically due to their resilient support.

Die Druckbalkensäge 10 umfaßt außerdem ein zweites Anschlagelement 88, das am Sägewagen 18 angeordnet ist. Es ist in Form eines Anschlagbolzens ausgestaltet und mittels einer Antriebsvorrichtung 90 senkrecht zur Sägelinie 20 und senkrecht zur Vorschubrichtung 46 verstellbar. Mittels der Antriebsvorrichtung 90, die vorzugsweise als druckmittelbeaufschlagbares Kolben-Zylinder-Aggregat ausgestaltet ist, kann das zweite Anschlagelement 88 zwischen einer über die Tischebene des Auflagetisches 14 überstehenden Anschlagstellung und einer Freigabestellung, in der das zweite Anschlagelement 88 unterhalb der Tischebene positioniert ist, hin- und herbewegt werden.The pressure beam saw 10 also includes a second stop member 88 disposed on the saw carriage 18. It is designed in the form of a stop pin and by means of a drive device 90 perpendicular to the saw line 20 and perpendicular to the feed direction 46 adjustable. By means of the drive device 90, which is preferably configured as a piston-cylinder unit which can be pressurized, the second stop element 88 can be positioned between a stop position projecting beyond the table plane of the support table 14 and a release position in which the second stop element 88 is positioned below the table plane. and be moved.

Die Steuerung der Antriebe des Transportschlittens 44, des Sägewagens 18 und des zweiten Anschlagelementes 88 erfolgt mittels einer Steuervorrichtung 92, die über in der Zeichnung nicht dargestellte, an sich bekannte Steuerleitungen mit den Antrieben in Verbindung steht.The control of the drives of the transport carriage 44, the saw carriage 18 and the second stop element 88 by means of a control device 92, which is not shown in the drawing, known control lines with the drives in combination.

Am Maschinengestell 12 sind auf der dem Transportschlitten 24 abgewandten Vorderseite 3 zueinander benachbarte Stützplatten 94 gehalten, die sich über schräg zur Vertikalen ausgerichtete Traversen 96 am Maschinengestell 12 abstützen. Die Stützplatten 94 und die Traversen 96 sind hohl ausgestaltet und definieren jeweils einen in der Zeichnung nicht dargestellten Luftkanal, über den von einem zentralen Gebläse (in der Zeichnung nicht dargestellt) eine Luftströmung zu auf der Oberseite der Stützplatten 94 angeordneten Luftaustrittsdüsen 98 geführt werden kann. Auf die Stützplatten 94, die sich lediglich am Maschinengestell 12, nicht aber auf einer Aufstandfläche der Druckbalkensäge 10 abstützen, kann ein über die Sägelinie 20 überstehender Bereich der aufzuteilenden Werkstücke aufgesetzt werden, wobei sich zwischen den Werkstücken und den Stützplatten 94 durch die Luftzufuhr ein Luftpolster ausbilden läßt, so daß die Werkstücke mit geringem Kraftaufwand verschoben werden können.On the machine frame 12, mutually adjacent support plates 94 are held on the front side facing away from the transport carriage 24, which are supported on the machine frame 12 via cross members 96 oriented obliquely to the vertical. The support plates 94 and the trusses 96 are hollow and define each one not shown in the drawing air duct over from a central fan (not shown in the drawing) an air flow to the top of the support plates 94 arranged air outlet nozzles 98 can be performed. On the support plates 94, which are supported only on the machine frame 12, but not on a contact surface of the pressure beam saw 10, over the saw line 20 projecting portion of the aufzuteilenden workpieces are placed, wherein between the workpieces and the support plates 94 by the air supply an air cushion training, so that the workpieces can be moved with little effort.

Soll ein plattenförmiges Werkstück, beispielsweise eine Holzplatte, mit schräg zu einer Längskante des Werkstückes verlaufendem Sägeschnitt mittels der Druckbalkensäge 10 aufgeteilt werden, so gibt der Benutzer zunächst die Abmessungen des Werkstückes sowie den Winkel, den der Sägeschnitt bezogen auf eine Längskante des Werkstückes einnehmen soll, über eine Tastatur 100 der Steuervorrichtung 92 ein. Diese umfaßt eine in Figur 2 schematisch dargestellte Recheneinheit 102, die die erforderlichen Positionsdaten für ein erstes Anschlagelement, beispielsweise das Anschlagelement 52, und das zweite Anschlagelement 88 berechnet und dem Benutzer die erforderliche Orientierung des Werkstückes schematisch auf einem Bildschirm 104 der Steuervorrichtung 92 anzeigt. Anschließend wird der Transportschlitten 44 mit dem Anschlagelement 52 nach vorne in eine der Sägelinie 20 benachbarte Stellung verfahren, so daß der Benutzer der Druckbalkensäge 10 den hinteren Eckbereich 86 des Werkstückes an die Anschlagschenkel 76 und 78 des ersten Anschlagelementes 52 anlegen kann. Die den Anschlagschenkeln 76 und 78 zugeordnete Spannbacke 66 wird dann mittels des Spannzylinders 62 betätigt, so daß der Eckbereich 86 des aufzuteilenden Werkstückes zwischen die Spannbacke 66 und den Drehteller 56 eingespannt wird.If a plate-shaped workpiece, for example, a wooden plate, with an obliquely to a longitudinal edge of the workpiece extending saw cut by means of the pressure beam saw 10 are divided, the user first gives the dimensions of the workpiece and the angle to take the saw cut relative to a longitudinal edge of the workpiece, via a keyboard 100 of the control device 92 a. This includes a computing unit 102 shown schematically in Figure 2, which calculates the required position data for a first stop element, for example, the stop element 52, and the second stop element 88 and the user the required orientation of the workpiece schematically on a screen 104 of the control device 92. Subsequently, the transport carriage 44 is moved with the stop element 52 forward in a sawing line 20 adjacent position so that the user of the pressure beam saw 10 can create the rear corner portion 86 of the workpiece to the stop legs 76 and 78 of the first stop element 52. The stop legs 76 and 78 associated jaw 66 is then actuated by means of the clamping cylinder 62, so that the Corner region 86 of the workpiece to be split between the jaw 66 and the turntable 56 is clamped.

In einem weiteren Verfahrensschritt wird der Transportschlitten 44 soweit nach hinten in die der Sägelinie 20 abgewandte Richtung verfahren, bis das erste Anschlagelement 52 die berechnete Position, also den berechneten Abstand a2 zur Sägelinie 20, eingenommen hat. Gleichzeitig wird der Sägewagen 18 mit abgesenkten Sägeeinheiten 22, 24 soweit entlang der Sägelinie 20 verfahren, bis das am Sägewagen 18 angeordnete zweite Anschlagelement 88 seine vorberechnete Position, nämlich den berechneten Abstand a1 zum ersten Anschlagelement 52 bezogen auf die Sägelinie 20, eingenommen hat. Das zweite Anschlagelement 88 wird dann mittels der Antriebsvorrichtung 90 nach oben in seine Anschlagstellung bewegt, so daß das aufzuteilende Werkstück zusammen mit dem ersten Anschlagelement 52 soweit um die Drehachse 58 verschwenkt werden kann, daß es mit einer Längskante am zweiten Anschlagelement 88 anliegt. Das Werkstück nimmt nun relativ zur Sägelinie 20 die erforderliche Orientierung ein, um den gewünschten schräg verlaufenden Sägeschnitt vornehmen zu können. Hierzu wird der Druckbalken 38 mittels der Führungsanordnungen 34 und 36 in Richtung auf den Auflagetisch 14 verfahren, so daß das aufzuteilende Werkstück unverschieblich am Auflagetisch 14 gehalten ist. Das zweite Anschlagelement 88 wird nun in seine Freigabestellung bewegt, und der Sägewagen 18 wird seitlich des aufzuteilenden Werkstückes positioniert. Anschließend werden die in vertikaler Richtung verstellbar am Sägewagen 18 gehaltenen Vorritz- und Kreissägen 22, 24 zur Vornahme des Sägeschnittes in vertikaler Richtung ausgefahren, so daß die zugeordneten Sägeblätter 26 bzw. 28 den Sägespalt 16 des Auflagetisches 14 durchgreifen und anschließend das Werkstück aufgetrennt werden kann. Hierbei wird der Sägewagen 18 entlang der Sägelinie 20 verfahren, und nach erfolgtem Sägeschnitt wird der Druckbalken 18 in seine zum Auflagetisch 14 beabstandete Stellung zurückbewegt.In a further method step, the transport carriage 44 is moved backwards in the direction away from the saw line 20 until the first stop element 52 has assumed the calculated position, that is to say the calculated distance a 2 to the saw line 20. At the same time, the saw carriage 18 with lowered saw units 22, 24 moves as far along the saw line 20 until the saw carriage 18 arranged second stop element 88 has its pre-calculated position, namely the calculated distance a 1 to the first stop element 52 with respect to the saw line 20, assumed. The second stop element 88 is then moved by means of the drive device 90 upwards into its stop position, so that the workpiece to be split together with the first stop element 52 can be pivoted so far about the axis of rotation 58 that it rests with a longitudinal edge on the second stop element 88. The workpiece now takes relative to the saw line 20 the required orientation to make the desired oblique saw cut can. For this purpose, the pressure bar 38 is moved by means of the guide assemblies 34 and 36 in the direction of the support table 14, so that the workpiece to be split is held immovably on the support table 14. The second stop member 88 is now moved to its release position, and the saw carriage 18 is positioned laterally of the workpiece to be split. The pre-scoring and circular saws 22, 24 held adjustably on the saw carriage 18 in the vertical direction are then extended in the vertical direction so that the associated saw blades 26 and 28 pass through the saw gap 16 of the support table 14 and subsequently the workpiece can be separated , Here is the Saw carriage 18 along the sawing line 20 method, and after sawing the pressure bar 18 is moved back to its position spaced from the support table 14 position.

Sollen mittels der Druckbalkensäge 10 zwei plattenförmige Werkstücke derart zugesägt werden, daß sie anschließend in einem vorgebbaren Winkel zueinander zusammengefügt werden können, so ist es hierzu lediglich erforderlich, daß der Benutzer die Abmessungen der beiden Werkstücke, also die jeweilige Länge L und Breite B, sowie den Winkel α, den die Werkstücke beim Zusammenfügen zueinander einnehmen sollen, mittels der Tastatur 100 in die Steuervorrichtung 92 eingibt. Die Recheneinheit 102 berechnet dann aufgrund der eingegebenen Daten die Winkel, den die Sägeschnitte der Werkstücke jeweils zu einer Längsseite einnehmen müssen. Auf dem Bildschirm 104 wird dann dem Benutzer schematisch die jeweils erforderliche Orientierung der beiden Werkstücke in der Druckbalkensäge 10 angezeigt. Dies ist in Figur 5 rechts dargestellt. Anschließend lassen sich die beiden Werkstücke wie voranstehend beschrieben mittels der ersten und zweiten Anschlagelemente positionieren und mit den erforderlichen schräg verlaufenden Sägeschnitten aufteilen.If by means of the pressure beam saw 10 two plate-shaped workpieces are to be sawn so that they can then be joined together at a predeterminable angle to each other, so it is only necessary that the user the dimensions of the two workpieces, ie the respective length L and width B, and the angle α, the workpieces are to take when mating to each other, by means of the keyboard 100 enters the control device 92. The arithmetic unit 102 then calculates, based on the data entered, the angle that the saw cuts of the workpieces each have to take to a longitudinal side. On the screen 104, the user then schematically displays the respectively required orientation of the two workpieces in the pressure beam saw 10. This is shown on the right in FIG. Subsequently, the two workpieces as described above can be positioned by means of the first and second stop elements and split with the required oblique saw cuts.
