Description

Die Erfindung betrifft eine Plattensäge mit aufrechtem Gestell gemäß Oberbegriff von Anspruch 1.The invention relates to a panel saw with an upright frame according to the preamble of claim 1.

Zum Ausführen von senkrechten Sägeschnitten ist es bei diesen Plattensägen bekannt, den Führungsbalken mit einer Rastvorrichtung mit dem Gestell zu verriegeln. An der Stelle des Sägeschnitts weisen dann die Auflageorgane, also z.B. die Auflageleisten des Auflagerostes, Einschnitte auf, in die das Sägeblatt beim Senkrechtschnitt eintauchen kann. Allerdings ist es bei diesen bekannten Plattensägen auch bei nicht verriegeltem Führungsbalken möglich, die Kreissäge in Richtung der Auflageorgane zu verschieben, so daß diese also bei fehlerhafter Bedienung der Maschine beschädigt werden könnte. Der Bedienungsmann muß also darauf achten, daß er die Kreissäge erst in ihre Eintauchstellung bringt, nachdem der Führungsbalken mit dem Gestell verriegelt ist.In order to make vertical saw cuts, it is known with these panel saws to lock the guide beam with the frame using a locking device. At the point of the saw cut, the support members, e.g. the support strips of the support grate, incisions into which the saw blade can plunge when making a vertical cut. However, in the case of these known panel saws, even when the guide bar is not locked, it is possible to move the circular saw in the direction of the support members, so that this could be damaged if the machine is operated incorrectly. The operator must therefore ensure that he only brings the circular saw into its immersion position after the guide bar has been locked to the frame.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung einer Plattensäge, bei der bei Senkrechtschnitten eine Beschädigung der Auflageorgane sicher vermieden wird.The object of the present invention is therefore to provide a panel saw in which damage to the support members is reliably avoided in the case of vertical cuts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein zusammen mit der Rastvorrichtung betätigbares erstes Sperrorgan vorgesehen ist, das in einer Sperrstellung in den Verschiebeweg der Kreissäge senkrecht zur Auflagefläche eingreift.This object is achieved in that a first locking element which can be actuated together with the latching device is provided and which, in a locking position, engages in the displacement path of the circular saw perpendicularly to the contact surface.

Damit läßt sich also die Kreissäge nur eintauchen, wenn der Führungsbalken mit dem Gestell sicher verriegelt ist. Eine Beschädigung der Auflageorgane ist ausgeschlossen und wegen der erfindungsgemäßen Zwangsverriegelung wird der Bedienungsmann entlastet.So that the circular saw can only be immersed if the guide bar is securely locked to the frame. Damage to the support members is excluded and the operator is relieved because of the forced locking according to the invention.

Greift gemäß Unteranspruch bei Eintauchstellung der Kreissäge ein mit dieser verbundenes zweites Sperrorgan in den Verschiebeweg des ersten Sperrorgans ein, dann läßt sich die Kreissäge erst wieder austauchen, also in ihre Ruhestellung verbringen, nachdem die Entriegelung zwischen Führungsbalken und Gestell gelöst ist. Die bedeutet, daß sich der Führungsbalken bei eingetauchter Kreissäge nicht seitlich verschieben läßt, so daß auch hier wieder eine Beschädigung der Auflageorgane sicher vermieden wird.If a second locking element connected to the circular saw engages in the displacement path of the first locking element when the circular saw is immersed, then the circular saw can only be replaced again, that is, spend in its rest position after the unlocking between the guide bar and frame has been released. This means that the guide bar cannot be moved laterally when the circular saw is immersed, so that damage to the support members is again reliably avoided.

Wird das Sperrorgan weiterhin erfindungsgemäB durch ein am Führungsbalken angeordnetes Schaltorgan zusammen mit der Rastvorrichtung betätigt, so ergibt sich eine besonders einfache Anordnung mit bequemer Bedienung über einen Schalthebel. Dieser kann in eine Ruhestellung bewegt werden, in der sich die Rastvorrichtung in Freigabestellung und das Sperrorgan in Sperrstellung befindet. In einer Raststellung des Schalthebels wird der Führungsbalken über die Rastvorrichtung mit dem Gestell verriegelt, während sich das Sperrorgan in Freigabestellung befindet. Die Kreissäge kann somit von Hand oder über einen kraftbetriebenen Antrieb eingetaucht werden.If, according to the invention, the locking member is further actuated by a switching member arranged on the guide bar together with the latching device, this results in a particularly simple arrangement with convenient operation via a shift lever. This can be moved into a rest position in which the latching device is in the release position and the locking member is in the locking position. In a latched position of the shift lever, the guide bar is locked to the frame via the latching device, while the locking member is in the release position. The circular saw can thus be submerged by hand or by a power drive.

Eine besonders vorteilhafte Anwendung kann die Erfindung bei Plattensägen mit Schwenkbarem Sägeblatt zur Ausführung von senkrechten und waagrechten Sägeschnitten finden. Bei diesen Plattensägen ist eine Klemmvorrichtung vorgesehen, mit der zur Ausführung von waagrechten Sägeschnitten der Schlitten am Führungsbalken festgeklemmt werden kann. ZweckmäBigerweise wird diese Klemmvorrichtung ebenfalls mit dem bereits vorhandenen Schalthebel betätigt, der von der Nullstellung in eine Klemmstellung bewegt werden kann. Bei dieser Klemmstellung befindet sich die Rastvorrichtung in Freigabestellung und das Sperrorgan in Sperrstellung. Da die Kreissäge jedoch in ihre waagrechte Schnittstellung verschwenkt ist, kann das Sperrorgan in diesem Fall nicht in den Verschiebeweg der Kreissäge eingreifen. Dazu dient ein Sperrhebel gemäß DE-A-27 13 520, der mit der Klemmvorrichtung zusammenwirkt. Dieser Sperrhebel bewirkt, daß bei waagrechtem Sägeschnitt ein Eintauchen erst nach Betätigung der Klemmvorrichtung möglich ist. Mit der Klemmvorrichtung kann weiterhin in bekannter Weise ein Ausweichrost so betätigt werden, daß die Auflageorgane bei waagrechten Sägeschnitten nicht beschädigt werden.The invention can find a particularly advantageous application in panel saws with a pivotable saw blade for executing vertical and horizontal saw cuts. In these panel saws, a clamping device is provided, with which the slide can be clamped to the guide beam in order to carry out horizontal saw cuts. This clamping device is also expediently actuated with the switching lever already present, which can be moved from the zero position into a clamping position. In this clamping position, the locking device is in the release position and the locking member is in the locking position. However, since the circular saw is pivoted into its horizontal cutting position, the locking element cannot intervene in the displacement path of the circular saw in this case. For this purpose, a locking lever according to DE-A-27 13 520, which interacts with the clamping device. This locking lever means that with a horizontal saw cut, immersion is only possible after the clamping device has been actuated. With the clamping device, an alternative grate can be operated in a known manner so that the support members are not damaged in horizontal saw cuts.

Die vorliegende Erfindung bietet also zusammen mit bereits bekannten Sperrvorrichtungen eine universelle Sicherung gegen Beschädigung der Auflageorgane und eine wesentliche Entlastung des Bedienungsmannes.The present invention, together with known locking devices, thus offers universal protection against damage to the support members and a substantial relief for the operator.

Im folgenden ist ein Ausführungsbeipiel der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.An exemplary embodiment of the invention is described in more detail below with reference to the drawings.

Die Fig. 1 und 2 zeigen ein leicht gegen die Senkrechte geneigtes Gestell 1. an dem die waagrechten Auflageorgane 2 eines Ausweichrostes höhenverschiebbar gelagert sind. An einem oberen Querträger 3 und einem unteren Querträger4 ist ein Führungsbalken 5 waagrecht verschiebbar gelagert. Er trägt einen Schlitten 6, der sich längs des Führungsbalkens 5 in Höhenrichtung verschieben läßt.1 and 2 show a frame 1 which is slightly inclined against the vertical and on which the horizontal support members 2 of an alternative grate are mounted so as to be vertically displaceable. On an upper cross member 3 and a lower cross member 4, a guide beam 5 is mounted horizontally. He carries a carriage 6, which can be moved along the guide beam 5 in the height direction.

Wie auch Fig. 3 zeigt, is an einer Führungsstange7 eine Kreissäge 8 gelagert, deren Sägeblatt 9 von einem Elektromotor 10 über einen Riementrieb 11 antreibbar ist.As also shown in FIG. 3, a circular saw 8 is mounted on a guide rod 7, the saw blade 9 of which can be driven by an electric motor 10 via a belt drive 11.

Mit Schlitten 6 ist eine Führungslasche 12 verbunden, die mit einer Führungsnut 13 versehen ist.A guide tab 12 is connected to the slide 6 and is provided with a guide groove 13.

Kreissäge 8 ist in Fig. 3 in ausgetauchter Stellung dargestellt, in der sowohl Führungsbalken 5 als auch Schlitten 6 frei verschoben werden können. Zur Ausführung eines senkrechten Sägeschnitts wird die Kreissäge 8 in Richtung der Auflageorgane 2 verschoben, die zusammen eine Auflagefläche 14 für ein nicht dargestelltes plattenförmiges Werkstück bilden (Fig. 4).Circular saw 8 is immersed in FIG. 3 Position shown, in which both the guide bar 5 and the carriage 6 can be moved freely. To carry out a vertical saw cut, the circular saw 8 is moved in the direction of the support members 2, which together form a support surface 14 for a plate-shaped workpiece (not shown) (FIG. 4).

Um bei eingetauchter Stellung des Sägeblatts 9 eine Beschädigung der Auflageorgane 2 zu verhindern, sind diese mit Einschnitten 15 versehen. Die Eintauchbewegung der Kreissäge 8 kann entweder von.Hand oder mittels eines kraftbetriebenen Antriebs erfolgen.In order to prevent damage to the support members 2 when the saw blade 9 is immersed, these are provided with incisions 15. The circular saw 8 can be immersed either by hand or by means of a power drive.

Zur Verriegelung zwischen Führungsbalken 5 und Gestell 1 ist am Führungsbalken 5 eine Rastvorrichtung 16 angeordnet, die einen oberen Rastbügel 17 und einen unteren Rastbügel 18 aufweist. Rastbügel 17 und Rastbügel 18 sind durch eine Raststange 19 miteinander verbunden.For locking between the guide bar 5 and frame 1, a latching device 16 is arranged on the guide bar 5, which has an upper latching bracket 17 and a lower latching bracket 18. Locking bracket 17 and locking bracket 18 are connected to each other by a locking rod 19.

Rastbügel 17 ist in einer Bohrung 20 im Oberwagen 21 an Führungsbalken 5 in Höhenrichtung verschiebbar geführt und umgreift in Raststellung Rastzapfen 22, die im oberen Querträger3 befestigt sind,Locking bracket 17 is guided in a bore 20 in the superstructure 21 on guide beams 5 so as to be displaceable in the vertical direction and, in the locking position, engages around locking pins 22 which are fastened in the upper cross member 3,

Der untere Rastbügel 18 wirkt in ähnlicher Weise mit Rastzapfen 23 zusammen, die im unteren Querträger 4 befestigt sind.The lower locking bracket 18 cooperates in a similar manner with locking pins 23 which are fastened in the lower cross member 4.

Raststange 19 ist in einem Schaltrohr 24 gelagert, das den Schlitten 6 durchdringt und gegenüber diesem durch einen Schalthebel 25 verdreht werden kann.Locking rod 19 is mounted in a switching tube 24 which penetrates the carriage 6 and can be rotated relative to the latter by a switching lever 25.

Eine am oberen Ende von Schaltrohr 24 angeordnete Hubplatte 26 ist mit geneigten Lappen 27 versehen, die auf eine Rolle 28 von Rastbügel 17 einwirken.A lifting plate 26 arranged at the upper end of the switching tube 24 is provided with inclined tabs 27 which act on a roller 28 of the locking bracket 17.

Wie Fig. 3 zeigt, weist das Schaltrohr 24 einen viereckigen Querschnitt auf und wird von einer Schalthülse 29 umfasst, die im Schlitten 6 drehbar gelagert ist. An Vorderwand 30 von Schlitten 6 ist weiterhin ein Sperrorgan 31 gegen Wirkung einer Druckfeder 32 waagrecht verschiebbar gelagert. Ein Schaltfinger33, der an einer Lasche 34 an Schalthülse 29 befestigt ist, greift in den in Fig. 3 und 4 gezeigten Stellungen in eine Nut 35 von Sperrorgan 31 ein.As shown in FIG. 3, the switching tube 24 has a square cross section and is encompassed by a switching sleeve 29 which is rotatably mounted in the carriage 6. On the front wall 30 of the carriage 6, a locking member 31 is furthermore mounted horizontally displaceably against the action of a compression spring 32. A shift finger 33, which is fastened to a tab 34 on the shift sleeve 29, engages in a groove 35 of the locking member 31 in the positions shown in FIGS. 3 and 4.

In der Vorderwand 30 von Schlitten 6 ist ein Durchbruch 36 vorgesehen, der in der in Fig. 3 gezeigten Stellung des Sperrorgans 31 von diesem nach innen überdeckt wird.In the front wall 30 of carriage 6, an opening 36 is provided, which in the position of the blocking member 31 shown in FIG. 3 is covered by this inward.

Mit der Kreissäge 8 ist ein zweites Sperrorgan 37 in Form einer Fingerplatte verbunden, das beim Eintauchen der Kreissäge 8 in den Durchbruch 36 eintritt. Das erste Sperrorgan 31 verhindert jedoch eine Weiterbewegung der Kreissäge 8 in Richtung Auflagefläche 14.A second locking member 37 in the form of a finger plate is connected to the circular saw 8 and enters the opening 36 when the circular saw 8 is immersed. The first locking member 31, however, prevents the circular saw 8 from moving further in the direction of the support surface 14.

Zur Ausführung von senkrechten Sägeschnitten muß zunächst der Führungsbalken 5 so verschoben werden, daß die Rastbügel 17 und 18 mit den entsprechenden Rastzapfen 22 und 23 fluchten. Wird jetzt Schalthebel 25 in die in Fig. 4 gezeigte Raststellung verschwenkt, dann nimmt die Schalthülse 29 das Schaltrohr 24 mit und die Hubplatte 26 verschiebt den oberen Rastbügel 17 nach unten,_bis er den Rastzapfen 22 umgreift. Gleichzeitig verschwenkt Raststange 19 den unteren Rastbügel 18 ebenfalls in Raststellung.To make vertical saw cuts, the guide bar 5 must first be moved so that the locking brackets 17 and 18 are aligned with the corresponding locking pins 22 and 23. If the shift lever 25 is now pivoted into the latching position shown in FIG. 4, the shift sleeve 29 takes the shift tube 24 with it and the lifting plate 26 moves the upper latching bracket 17 downward until it engages around the latching pin 22. At the same time locking rod 19 pivots the lower locking bracket 18 also in the locking position.

Beim Verschwenken von Schalthülse 29 wird jedoch auch Schaltfinger33 mitgenommen, der somit das erste Sperrorgan 31 in seine in Fig. 4 gezeigte Freigabestellung verschiebt. Damit wird Durchbruch 36 freigegeben und die Kreissäge 8 kann ungehindert gegen die Auflagefläche 14 verschoben werden. Dabei gelangt das zweite Sperrorgan 37 durch den Durchbruch 36 so vor das erste Sperorgan 31, daß dieses nicht mehr in seine Sperrstellung verschoben werden kann. Erst wenn nach Ausführung des senkrechten Sägeschnitts die Kreissäge 8 wieder völlig ausgetaucht ist, gibt das zweite Sperrorgan 37 den Verschiebeweg des ersten Sperrorgans 31 frei und Schalthebel 25 kann wieder in seine in Fig. 3 gezeigte Ruhestellung verschwenkt werden, wobei die Verriegelung zwischen Führungsbalken 5 und Gestell 1 gelöst wird.When pivoting the switching sleeve 29, however, the shift finger 33 is also carried, which thus moves the first locking member 31 into its release position shown in FIG. 4. This opens breakthrough 36 and the circular saw 8 can be moved freely against the bearing surface 14. The second locking member 37 passes through the opening 36 in front of the first locking member 31 so that it can no longer be moved into its locked position. Only when the circular saw 8 has been completely immersed again after the vertical saw cut has been made, does the second locking member 37 release the displacement path of the first locking member 31 and shift lever 25 can be pivoted back into its rest position shown in FIG. 3, the locking between guide bars 5 and Frame 1 is solved.

Bei einer vorteilhaften Ausführungsform der Erfindung wirkt Schalthülse 29 so auf eine Klemmvorrichtung 38 ein, daß Schlitten 6 am Führungsbalken 5 festgeklemmt wird, wenn Schalthebel 25 in die in Fig. 3 strichpunktiert gezeichnete Klemmstellung verschwenkt wird. Dabei wird Schaltfinger 33 aus der Nut 35 vom ersten Sperrorgan 31 ausgehoben, Sperrorgan 31 deckt also Durchbruch 36 nach innen ab.In an advantageous embodiment of the invention, the switching sleeve 29 acts on a clamping device 38 such that the slide 6 is clamped on the guide bar 5 when the switching lever 25 is pivoted into the clamping position shown in broken lines in FIG. 3. The shift finger 33 is lifted out of the groove 35 by the first locking member 31, so locking member 31 thus covers opening 36 toward the inside.

Die Klemmvorrichtung 38 wird jedoch nur dann betätigt, wenn waagrechte Sägeschnitte ausgeführt werden sollen. Dazu wird die Kreissäge 8 in die in Fig. 1 strichpunktiert gezeichnete Stellung verschwenkt, wobei das zweite Sperrorgan 37 mit der Führungsnut 13 fluchtet und beim Eintauchen der Kreissäge 8 der genauen Führung dieser Kreissäge dient. Vor dem Eintauchen muß allerdings in bekannter Weise ein Sperrhebe) 39 mit dem Schalthebel 25 in die in Fig. 1 strichpunktiert gezeichnete Freigabestellung verschwenkt werden.However, the clamping device 38 is only actuated when horizontal saw cuts are to be carried out. For this purpose, the circular saw 8 is pivoted into the position shown in dot-dash lines in FIG. 1, the second locking member 37 being aligned with the guide groove 13 and serving for the precise guidance of this circular saw when the circular saw 8 is immersed. Before immersion, however, a locking lever 39 must be pivoted in a known manner with the shift lever 25 into the release position shown in broken lines in FIG. 1.

Die Schalthülse 29 kann weiterhin in bekannter Weise dazu dienen, über ein nicht dargestelltes Kupplungselement beim waagrechten Sägeschnitt die Auflageorgane 2 aus der Bahn des Sägeblatts 9 herauszubewegen.The switching sleeve 29 can also serve in a known manner to move the support members 2 out of the path of the saw blade 9 in a horizontal saw cut via a coupling element (not shown).

Der Bedienungsmann ist also mit einem einzigen Schalthebel 25 in der Lage, bei senkrechten Sägeschnitten den Führungsbalken zu verriegeln und die Sperre für die Eintauchbewegung der Kreissäge 8 aufzuheben und bei. waagrechten Sägeschnitten in einer weiteren Klemmstellung den Schlitten 6 am Führungsbalken 5 festzuklemmen und, soweit gegeben, die Auflageorgane 2 aus der Bahn des Sägeblattes 9 auszuheben. Diese Einhandbedienung über einen einzigen Schalthebel entlastet den Bedienungsmann und erlaubt eine schnellere und bequemere Handhabung der Plattensäge.The operator is therefore in a position with a single shift lever 25 to lock the guide bar in the case of vertical saw cuts and to remove the lock for the immersion movement of the circular saw 8 and at. horizontal saw cuts in a further clamping position to clamp the carriage 6 on the guide beam 5 and, if given, lift the support members 2 out of the path of the saw blade 9. This one-hand operation via a single switch lever relieves the operator and allows faster and more convenient handling of the panel saw.
