PATENTANSPRUCH Werkstückbezogene Vorschubwegbegrenzung eines fahrbaren Sägeaggregates einer Plattensäge mit Werkstückvorschubeinrichtung, die mit Spanneinrichtungen für das Werkstück ausgestattet ist, dadurch gekennzeichnet, dass die Spanneinrichtung (5) mit Schaltern versehen und den Spanneinrichtungen (5) gegenüber am Maschinenbett weitere Schalter (7) angeordnet sind, wobei bei eingespanntem Werkstück diejenigen Schalter der zum Festspannen des Werkstückes (6) nicht benötigten Spanneinrichtungen (5) die ihnen gegenüberliegenden Schalter (7) aktivieren, derart, dass sie den Weg des längs einer Schnittlinie (2) fahrenden Sägeaggregates begrenzen. PATENT CLAIM Workpiece-related feed path limitation of a mobile saw unit of a panel saw with workpiece feed device, which is equipped with clamping devices for the workpiece, characterized in that the clamping device (5) is provided with switches and further switches (7) are arranged opposite the clamping devices (5) on the machine bed, wherein when the workpiece is clamped, those switches of the clamping devices (5) not required for clamping the workpiece (6) activate the switches (7) opposite them in such a way that they limit the path of the saw unit traveling along a cutting line (2). Die Erfindung betrifft eine werkstückbezogene Vorschubwegbegrenzung eines fahrbaren Sägeaggregates einer Plattensäge mit Werkstückvorschubeinrichtung, die mit Spanneinrichtung für das Werkstück ausgestattet ist. Bei Plattensägen mit fahrbarem Sägeaggregat ist es notwendig, den Fahrweg des Sägeaggregates entsprechend der Grösse des zu sägenden Werkstückes, zur Erreichung einer optimalen Leistung und Vermeidung von toten Fahrzeiten zu bestimmen.The invention relates to a workpiece-related feed path limiter for a mobile saw unit of a panel saw with a workpiece feed device that is equipped with a clamping device for the workpiece. In the case of panel saws with a mobile sawing unit, it is necessary to determine the travel path of the sawing unit according to the size of the workpiece to be sawed in order to achieve optimum performance and avoid dead travel times. Dies wird mit entsprechenden Einstellvorrichtungen über einstellbare Endschalter oder verstellbare mechanische Stoppeinrichtungen erreicht. Solche Einrichtungen müssen jeweils vor dem Start der Säge entsprechend der Werkstückgrösse positioniert werden. Dies ist insbesondere dann, wenn die Werkstücke in ihrer Grösse laufend wechseln, ein umständlicher und zeitaufwendiger Vorgang, der ausserdem immer von der Sorgfalt des Bedienungsmannes abhängig ist und darüberhinaus kostspielige mechanische Einrichtungen für die Verschiebung solcher Vorrichtungen erforderlich macht.This is achieved with appropriate setting devices via adjustable limit switches or adjustable mechanical stop devices. Such devices must be positioned according to the workpiece size before starting the saw. This is particularly when the workpieces are constantly changing in size, a cumbersome and time-consuming process, which also always depends on the care of the operator and, moreover, requires expensive mechanical equipment for moving such devices. Der Erfindung liegt deshalb die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Vorschubwegbegrenzung zu schaffen, bei der eine Positionierung der Stoppeinrichtungen entsprechend der Werkstückgrösse entfällt.The invention is therefore based on the object of avoiding these disadvantages and of creating a feed path limitation in which there is no need to position the stop devices according to the size of the workpiece. Erfindungsgemäss wird dies dadurch erreicht, dass die Spanneinrichtungen mit Schaltern versehen und den Spanneinrichtungen gegenüber am Maschinenbett weitere Schalter angeordnet sind, wobei bei eingespanntem Werkstück die-5 jenigen Schalter der zum Festspannen des Werkstückes nicht benötigten Spanneinrichtungen die ihnen gegenüberliegenden Schalter aktivieren derart, dass sie den Weg des längs einer Schnittlinie fahrenden Sägeaggregates begrenzen. Dabei wird der Weg durch die Grösse des aufgelegten Werk-10 stückes ohne jegliche vorherige Einstellung bestimmt.According to the invention, this is achieved in that the clamping devices are provided with switches and further switches are arranged opposite the clamping devices on the machine bed, with the workpiece being clamped, those switches of the clamping devices not required for clamping the workpiece activate the switches opposite them in such a way that they Limit the path of the saw unit traveling along a cutting line. The path is determined by the size of the workpiece placed on it without any previous setting. Eine schematische Darstellung dieser Einrichtung gibt die Figur der beiliegenden Zeichnung in einer Draufsicht. Im.Maschinenbette einer Plattensäge 1 fährt ein fahrbares Sägeaggregat mit hochtauchendem Sägeblatt, welches hier 15 nicht näher dargestellt worden ist. Das Werkstück 6 wird in die Spannvorrichtung 5 der Werkstückvorschubeinrichtung 4 eingeschoben und durch den programmierbaren Werkstückvorschub in die gewünschte Schnittposition gebracht. Sobald das Werkstück eingelegt und in den Spannvorrich-20 tungen gespannt ist, werden durch die entsprechende Werkstückgrösse nicht benützten Spannvorrichtungen 5, die gegenüberliegenden Schaltelemente 7 funktionstüchtig gemacht. Beim Sägeschnitt läuft das Sägeaggregat entsprechend der Pfeilrichtung 8 vor, sägt das Werkstück durch und wird das 25 Schaltelement 7 nach beendetem Schnitt gestoppt. Das Sägeaggregat muss so die jeweils der Werkstückgrösse entsprechende Länge bei seinem Vorlauf zurücklegen. Nach Schnittende senkt das Sägeblatt ab und fährt unter dem Tisch wieder zurück, während dieser Zeit schiebt der Werkstückvor-30 schub in den Führungsbahnen 3 das Werkstück in die nächste Schnittposition.A schematic representation of this device is given in the figure of the accompanying drawing in a plan view. In the machine bed of a panel saw 1 moves a mobile saw unit with a high-cut saw blade, which has not been shown in detail here. The workpiece 6 is pushed into the clamping device 5 of the workpiece feed device 4 and brought into the desired cutting position by the programmable workpiece feed. As soon as the workpiece is inserted and clamped in the clamping devices, the clamping devices 5 that are not used and the opposite switching elements 7 are made functional by the corresponding workpiece size. During the saw cut, the saw unit advances in the direction of the arrow 8, saws through the workpiece and the switching element 7 is stopped after the cut is complete. In this way, the sawing unit has to cover the length corresponding to the size of the workpiece during its advance. After the end of the cut, the saw blade lowers and moves back under the table. During this time, the workpiece feed in the guideways 3 pushes the workpiece to the next cutting position. Das gleiche System kann auch für die Bestimmung des Auftauchpunktes der Säge verwendet werden. In diesem Fall fährt das Sägeaggregat entgegengesetzt der Pfeilrichtung 35 8 und wird beim Rücklauf, nach erfolgtem Schnitt durch das Schaltelement 7 gestoppt, so dass beim nächsten Schnitt der Start- und Auftauchpunkt unmittelbar an der Kante des Werkstückes liegt.The same system can also be used to determine the emergence point of the saw. In this case, the sawing unit moves in the opposite direction of the arrow 35 8 and is stopped by the switching element 7 on the return run after the cut has been made, so that the start and emergence point for the next cut is directly at the edge of the workpiece. vv 1 Blatt Zeichnungen1 sheet of drawings
