Description

Die Erfindung betrifft eine Tischsäge gemäß dem Oberbegriff des Anspruchs 8, sowie einen Schiebestock dafür gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a table saw according to the preamble of claim 8, and a push stick therefor according to the preamble of claim 1.

Tischsägen der gattungsgemäßen Art weisen einen Maschinentisch auf, der von einem motorbetriebenen Sägeblatt durchgriffen wird. Werkstücke werden dabei auf dem Maschinentisch abgelegt und zum Sägeblatt hin geschoben, wo dann das Sägeblatt in Angriff an das Werkstück gelangt und es bei weiterem Vorschub zersägt.Table saws of the generic type have a machine table, which is penetrated by a motor-driven saw blade. Workpieces are placed on the machine table and pushed towards the saw blade, where then the saw blade comes into attack on the workpiece and sawed it on further feed.

Arbeiten an solchen Tischsägen, beispielsweise Tischkreissägen oder auch an Tischbandsägen sind mit erheblichen Gefahren verbunden. Insbesondere die das zu sägende Werkstück führende Hand des Maschinenbedieners ist dabei der Gefahr ausgesetzt, unbeabsichtigt über das Sägeblatt geführt und dabei schwer verletzt zu werden.Working on such table saws, such as table saws or table band saws are associated with significant risks. In particular, the hand of the machine operator leading the workpiece to be sawn is exposed to the danger of being inadvertently guided over the saw blade and being seriously injured.

Zum Schutz des Maschinenbedieners und insbesondere seiner das Werkstück führenden Hand sind daher bereits verschiedene Vorrichtungen bekannt. So zeigt die US 4,370,909 eine Handschutzvorrichtung, deren Handgriff ein Vorbeiführen des Werkstücks am Sägeblatt erlaubt, ohne dass die dafür benutzte Hand in Kontakt mit dem Sägeblatt kommen kann. Dabei ist ein Totmann-Schalter am Hangriff vorgesehen, bei dessen Loslassen der Motor der Säge abgeschaltet wird.For the protection of the machine operator and in particular his hand leading the workpiece are therefore already known various devices. That's how it shows US 4,370,909 a hand guard whose handle allows the workpiece to pass the saw blade without the hand used to come into contact with the saw blade. In this case, a deadman switch is provided on the hangriff, when it is released, the motor of the saw is turned off.

Ähnliches zeigt die US-Patentschrift US 7,989,718 B1 , bei der an dem Handgriff der Handschutzvorrichtung ein Schalter zum Ein- und Ausschalten der Stromversorgung der Kreissäge vorgesehen ist und zusätzlich eine Anzeigenleuchte, die den Zustand des Schalters angibt.The same shows the US Pat. No. 7,989,718 B1 in which a switch for switching on and off the power supply of the circular saw is provided on the handle of the hand protection device and in addition a Indicator light indicating the state of the switch.

Weiterhin ist in der Gebrauchsmusterschrift DE 20 2005 010 656 U1 ein Parallelanschlag für eine Tischkreissäge zu entnehmen, welche eine Vorschubklinge aufweist, die durch einen Handgriff in Schnittrichtung bewegt wird, um das Werkstück an der Säge vorbeizuführen. An den Enden des Verfahrweges der Vorschubklinge sind dabei Kontaktschalter vorgesehen.Furthermore, in the utility model DE 20 2005 010 656 U1 to take a rip fence for a table saw, which has a feed blade which is moved by a handle in the cutting direction to pass the workpiece on the saw. At the ends of the travel of the feed blade while contact switch are provided.

Gemäß der Norm EN62841-3-1 muss jede Tischkreissäge mit einem sog. Schiebestock versehen sein. Ist die Breite des zu sägenden Werkstückes kleiner als 10 cm, soll bereits der Schiebestock verwendet werden, um eine versehentliche Berührung des Sägeblatts durch die Hand zu vermeiden. Ein solcher Schiebestock ist dem Gebrauchsmuster DE 20 2010 004 458 U1 zu entnehmen, wobei dort zusätzlich eine Schutzhaube über dem Sägeblatt und eine Sensorik an der Tischkreissäge vorgesehen ist, mit der ein Körperteil eines Benutzers erfasst wird.According to the standard EN62841-3-1 each table saw must be equipped with a so-called push stick. If the width of the workpiece to be sawn is less than 10 cm, the push stick should already be used in order to avoid accidental contact of the saw blade with the hand. Such a push stick is the utility model DE 20 2010 004 458 U1 can be seen, where there is additionally provided a protective cover over the saw blade and a sensor on the table saw, with a body part of a user is detected.

Gemäß der Norm EN61029-2-5 bzw. EN1807 sind auch Tischbandsägen mit einem Schiebestock auszurüsten.According to the EN61029-2-5 or EN1807 standard, table-top saws must also be equipped with a push stick.

Ein solcher Schiebestock der gattungsgemäßen Art weist an seinem einen Ende eine Greifmöglichkeit für den Maschinenbediener und auf seinem anderen Ende eine Ecknut bzw. eine Einkerbung oder Werkstückangriffskerbe auf, um an dem Werkstück anzugreifen. Dazu hat die Werkstückangriffskerbe zwei zueinander unter einem vorzugsweise rechten Winkel angeordneten Flächen, eine in Vorschubrichtung des Werkstücks weisenden Schiebefläche und eine von oben auf das Werkstück drückenden Niederhaltefläche.Such a push stick of the generic type has at its one end a gripping possibility for the machine operator and on its other end a Ecknut or a notch or workpiece engaging notch to attack on the workpiece. For this purpose, the workpiece engaging notch has two surfaces arranged at a preferably right angle to one another, a sliding surface pointing in the feed direction of the workpiece, and a hold-down surface pressing from above onto the workpiece.

Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, die Arbeit an einer mortorbetriebenen Tischsägen, wie beispielsweise an einer Tischkreissäge oder einer Tischbandsäge mit einfachen Mitteln sicherer zu machen.On this basis, it is an object of the present invention to make safer work on a mortor-driven table saws, such as a table saw or a band saw with simple means.

Diese Aufgabe wird hinsichtlich eines Schiebestocks mit den Merkmalen des Anspruchs 1 gelöst, hinsichtlich einer Tischkreissäge mit den Merkmalen des Anspruchs 8.This object is achieved in terms of a sliding stick with the features of claim 1, with respect to a table-top circular saw with the features of claim 8.

Ausgehend von einem gattungsgemäßen Schiebestock weist der erfindungsgemäße Schiebestock somit eine Greifmöglichkeit für einen Maschinenbediener an seinem bedienerseitigen Ende auf, und ferner an seinem davon beabstandeten, werkstückseitigen Ende eine zum Angriff an das Werkstück geeignete Werkstücksangriffskerbe, welche eine in Werkstückvorschubrichtung weisende Schiebefläche und eine davon oberseitig unter einem Winkel vorspringende Niederhaltefläche aufweist. Erfindungsgemäß weist der Schiebestock nun ferner eine Erfassungseinrichtung auf, welche erfasst, ob die Schiebefläche und die Niederhaltefläche plan an dem Werkstück anliegen, sowie eine Signalgebereinrichtung, welche im Ansprechen darauf, ob die Erfassungseinrichtung eine solche Plananlage der Schiebefläche und der Niederhaltefläche erfasst oder nicht, ein entsprechendes Plananlage-Signal gibt, welches also signalisiert, ob die Schiebefläche und die Niederhaltefläche plan an dem Werkstück anliegen oder nicht. Dabei wird der Winkel, unter dem die Niederhaltefläche von der Schiebefläche vorspringt, in der Regel ein rechter Winkel sein, da die zu sägenden Werkstücke in der Regel Bretter mit rechtwinklig aneinander grenzenden Seitenkanten sind. Für Spezialanwendungen könnte jedoch auch ein anderer Winkel vorgesehen sein.Starting from a generic push stick, the push stick according to the invention thus has a gripping possibility for a machine operator at its operator end, and also at its spaced, workpiece side end suitable for attacking the workpiece workpiece engaging notch, which pointing in the workpiece feed direction sliding surface and one of the upper side below Having an angle projecting hold-down surface. According to the invention, the push stick now further comprises a detection device, which detects whether the sliding surface and the hold-down surface rest flush against the workpiece, and a signaling device, which in response to whether the detection device detects such a plane system of the sliding surface and the hold-down surface or not corresponding plan contact signal is, which therefore signals whether the sliding surface and the hold-down plane abut the workpiece or not. In this case, the angle at which the hold-down surface protrudes from the sliding surface, is usually a right angle, since the workpieces to be sawn are usually boards with right angles adjacent side edges. For special applications, however, another angle could be provided.

Die erfindungsgemäße Tischsäge ist entsprechend mit einem solchen Schiebestock ausgerüstet. Die erfindungsgemäße Tischsäge kann dabei ein einen Maschinentisch durchgreifendes, motorbetriebenes Sägeblatt aufweisen und kann beispielsweise als Tischkreissäge oder als Tischbandsäge ausgebildet sein.The table saw according to the invention is accordingly equipped with such a push stick. The table saw according to the invention can in this case have a motor-driven saw blade which passes through a machine table and can be designed, for example, as a table-top circular saw or as a table-top saw.

Dadurch, dass nun erfasst und signalisiert wird, ob sowohl die Schiebefläche als auch die Niederhaltefläche plan an dem Werkstück aufliegen, kann ein Abrutschen des Schiebestocks während der Werkstückzufuhr zum Sägeblatt vermieden werden. Ein eine zusätzliche Gefahrenquelle darstellendes nach vorne Beugen des Maschinenbedieners zur visuellen Überprüfung, ob beide Flächen plan auf dem Werkstück aufliegen, kann somit entfallen. Vielmehr erhält der ja am anderen Ende des Schiebestocks zugreifende Maschinenbediener erstmals die Möglichkeit, mit Sicherheit festzustellen, ob Plananlage am Werkstück vorherrscht oder nicht.The fact that now detected and signaled whether both the sliding surface and the hold-down surface rest flat against the workpiece, slipping of the push stick can be avoided during the workpiece feed to the saw blade. An additional source of danger is forward bending the machine operator for visual inspection, whether both surfaces rest flat on the workpiece, can thus be omitted. On the contrary, the machine operator accessing the other end of the sliding stick for the first time has the opportunity to ascertain with certainty whether or not there is a contact surface on the workpiece.

Vorteilhafte Weiterbildungen sind Gegenstand der übrigen Unteransprüche.Advantageous developments are the subject of the remaining dependent claims.

So kann die Erfassungseinrichtung an der Schiebefläche und an der Niederhaltefläche jeweils zumindest einen versenkten Tastschalter aufweisen, welcher angibt, ob die jeweilige Fläche an dem Werkstück anliegt oder nicht. Die Tastschalter sind dabei weiter bevorzugt gegenüber der Schiebefläche bzw. der Niederhaltefläche versenkt angebracht, und zwar vorteilhaft so versenkt, dass eine Betätigung des jeweiligen Tastschalters nur erfolgt, wenn die jeweilige Fläche plan an dem Werkstück aufliegt.Thus, the detection device on the sliding surface and on the hold-down surface each have at least one recessed push-button switch, which indicates whether the respective surface is applied to the workpiece or not. The key switches are further preferred sunk relative to the sliding surface or the hold-down, and advantageously so sunk that actuation of the respective key switch only takes place when the respective surface rests flat on the workpiece.

Die Taster bzw. Tastschalter können dabei als Mikrotaster ausgebildet sein. Sind die beiden Taster vorteilhaft in einem UND-Gatter geschaltet, so dass die Erfassungseinrichtung eine Plananlage nur dann erfasst, wenn beide Mikrotaster durch den per Werkstück ausgeübten Druck betätigt werden, so ergibt sich ein einfacher und zuverlässiger Aufbau.The buttons or push buttons can be designed as a micro-probe. If the two buttons are advantageously connected in an AND gate, so that the detection device only detects a plane contact when both micro buttons are actuated by the pressure exerted by the workpiece, the result is a simple and reliable construction.

Alternativ oder ergänzend kann die Erfassungseinrichtung auch eine elektrooptische oder elektroakkustische Abtastvorrichtung aufweisen, welche erfasst, ob die Schiebefläche und die Niederhaltefläche plan an dem Werkstück aufliegen.Alternatively or additionally, the detection device can also have an electro-optical or electroacoustic scanning device, which detects whether the sliding surface and the hold-down surface lie flat against the workpiece.

Die Signalgebereinrichtung kann dagegen eine LED oder eine andere Leuchte umfasst, welche bei Plananlage leuchtet, also beispielsweise dann, wenn das UND-Gatter durch einen vom Werkstück auf die beiden Mikrotaster an der Schiebefläche und der Niederhaltefläche ausgeübten Druck geschlossen ist. Alternativ oder ergänzend wäre selbstverständlich auch eine andere Art von Signalgeber, beispielsweise ein akustischer Alarm bei nicht gegebener Plananlage oder ein entsprechendes Vibrationsfeedback, denkbar.On the other hand, the signaling device may comprise an LED or another light which illuminates when the installation is flat, for example when the AND gate is closed by a pressure exerted by the workpiece on the two micro-buttons on the sliding surface and the hold-down surface. Alternatively or additionally, of course, would be another type of Signal generator, such as an audible alarm when not given plan system or a corresponding vibration feedback, conceivable.

Weist die Signalgebereinrichtung eine drahtgebundene oder vorzugsweise drahtlose Kommunikationsschnittstelle auf, wie beispielsweise eine Bluetooth- oder Wifi-Schnittstelle, über welche das Plananlage-Signal übertragbar ist, und die Maschinensteuerung der Tischsäge eine entsprechende, zugeordnete Kommunikationsschnittstelle, so kann das Plananlage-Signal auch maschinenseitig ausgewertert werden.If the signaling device has a wired or preferably wireless communication interface, such as, for example, a Bluetooth or Wifi interface via which the scheduling signal can be transmitted, and the machine control of the table saw has a corresponding, assigned communication interface, then the scheduling signal can also be evaluated on the machine side become.

So kann die Maschinensteuerung allgemein ein Stellglied und eine Betätigungseinrichtung für das Stellglied umfasst, welche das Stellglied im Ansprechend darauf betätigt, ob das Plananlage-Signal signalisiert, ob die Schiebefläche und die Niederhaltefläche plan an dem Werkstück anliegen oder nicht. Als Stellglied kommt dabei hauptsächlich ein AN/AUS-Schalter für den Antrieb des Sägeblatts in Frage, um eine Anschalten der Tischkreissäge nur bei per Schiebestück plan geführtem Werkstück zu erlauben. Denkbar als Stellglied wäre auch ein Notauss-Schalter, oder sogar eine bremse für das Sägeblatt, um das Sägeblatt möglichst schnell anzuhalten, wenn keine Plananlage mehr gegeben ist.Thus, the machine controller may generally include an actuator and an actuator actuator that actuates the actuator in response to whether or not the faceplate signal indicates whether or not the sliding surface and the holddown surface are planar against the workpiece. As an actuator is mainly an ON / OFF switch for driving the saw blade in question, to allow turning on the table saw only when planed by sliding piece workpiece. Conceivable as an actuator would be an emergency stop switch, or even a brake for the saw blade to stop the saw blade as soon as possible, if no more plan system is given.

Zur Auswertung des von den Tastern der Erfassungseinrichtung abgegebenen Plananlage-Signals ist dabei vorteilhaft eine Entprelleinrichtung zum Entprellen des Plananlagesignals vorgesehen, wobei die Entprelleinrichtung vorzugsweise einen Tiefpassfilter, ein Flip-Flop und/oder einen Mikrocontroller mit Entprellsoftware aufweist. Die Entprelleinrichtung kann dabei Teil der Signalgebereinrichtung am Schiebestock oder Teil der Maschinensteuerung an der Tischsäge sein.To evaluate the output from the probes of the detection device Plananlage signal is advantageously a Entprelleinrichtung for debouncing the Plananlagesignals provided, the debounce preferably has a low-pass filter, a flip-flop and / or a microcontroller with Entprellsoftware. The debouncing device may be part of the signaling device on the push stick or part of the machine control on the table saw.

Weiterhin vorteilhaft ist zur Stromversorgung der Erfassungseinrichtung und der Signalgebereinrichtung am Schiebestock eine Knopfzellenaufnahme vorgesehen, in die eine Knopfzelle eingelegt ist. Insbesondere bei einer kabelgebundenen Plansignalübertragung wäre aber auch eine kabelgebundene Stromversorgung denkbar.Further advantageous for the power supply of the detection device and the signaling device on the push stick a button cell receptacle is provided, in which a button cell is inserted. Especially with a wired Planetsignalübertragung but also a wired power supply would be conceivable.

Im Folgenden wird anhand der beiliegenden Zeichnungen eine vorteilhafte Ausführungsform der Erfindung näher erläutert. Es zeigen:

Figur 1
eine Seitenansicht einer vorteilhaften Ausführungsform eines Schiebestocks;
Figur 2
eine perspektivische Frontansicht des in Figur 1 Schiebestocks; und
Figur 3
ein Schaltbild des in den Figuren 1 und 2 gezeigten Schiebestocks.
In the following an advantageous embodiment of the invention will be explained in more detail with reference to the accompanying drawings. Show it:
FIG. 1
a side view of an advantageous embodiment of a push stick;
FIG. 2
a front perspective view of the FIG. 1 Stocks Slide; and
FIG. 3
a diagram of the in the FIGS. 1 and 2 shown sliding sticks.

Zunächst wird Bezug genommen auf die Figuren 1 und 2, welche einen Schiebestock 3 zeigen, der an seinem in der Figur 1 rechten Ende von einem Maschinenbediener einer Tischkreissäge oder Tischbandsäge ergriffen werden kann, um mit seinem in der Figur 1 linken Ende an einer dort vorgesehenen Werkstückangriffskerbe in Angriff an ein an einem Sägeblatt der Tischkreissäge/Tischbandsäge vorbei zu schiebenden Werkstück gebracht werden kann. Die Werkstückangriffskerbe weist dazu eine Schiebefläche 1 und eine davon oberseitig im rechten Winkel zum Werkstück hin vorspringende Niederhaltefläche 2 auf, so dass der Schiebestock 3 mit seiner Schiebefläche 1 und seiner Niederhaltefläche 2 plan an einem beispielsweise als Brett mit rechtwinklig aneinander grenzenden Seitenflächen ausgebildeten Werkstück angesetzt werden kann.First, reference is made to the FIGS. 1 and 2 , which show a push stick 3, at his in the FIG. 1 Right end can be grasped by a machine operator of a table saw or band saw to work with his in the FIG. 1 left end can be brought to a provided there on a workpiece engaging notch in attack on a saw blade of the table saw / table band saw to be pushed workpiece. For this purpose, the workpiece engagement notch has a sliding surface 1 and a hold-down surface 2 protruding therefrom at right angles to the workpiece, so that the push stick 3 with its sliding surface 1 and its hold-down surface 2 is attached flat to a workpiece formed, for example, as a board with side faces that are perpendicular to one another can.

An der Schiebefläche 1 und an der Niederhaltefläche 2 des Schiebestocks 3 befinden sich versenkt zwei Mikrotaster bzw. Mikroschalter 4. Die Abtastung könnte anstelle oder ergänzend zu diesen elektromechanischen Komponenten auch durch eine elektrooptische oder elektroakustische Abtastung erfolgen, solange die dadurch gebildete Erfassungseinrichtung 4 erfasst, ob die Schiebefläche 1 und die Niederhaltefläche 2 plan an dem Werkstück anliegen.On the sliding surface 1 and on the hold-down surface 2 of the sliding stick 3 are located two sunk microswitch or microswitch 4. The sampling could be done instead of or in addition to these electromechanical components by an electro-optical or electro-acoustic scanning, as long as the detection device 4 formed thereby detects whether the sliding surface 1 and the hold-down surface 2 rest flat against the workpiece.

Weiterhin weist der Schiebestock 3 eine LED 5 auf, welche als Signalgebereinrichtung 5 dient, die im Ansprechen darauf, ob die durch die beiden Mikrotaster 4 gebildete Erfassungseinrichtung 4 die Plananlage der Schiebefläche 1 und der Niederhaltefläche 2 an dem Werkstück erfasst oder nicht, ein Plananlage-Signal gibt, welches signalisiert, ob die Schiebefläche 1 und die Niederhaltefläche 2 plan an dem Werkstück anliegen oder nicht. Im Ausführungsbeispiel leuchtet die LED 5 also bei Plananlage. Es könnte natürlich auch so sein, dass die LED 5 als Warnleuchte dann leuchtet, wenn keine beiderseitige Plananlage gegeben ist. Ferner könnte die Signalgebereinrichtung 5 alternativ oder ergänzend zu der LED 5 auch einen anderen Signalgeber aufweisen, beispielsweise einen akustischen Signalgeber oder einen Vibrationsalarm. Weiterhin wäre es denkbar, dass die Signalgebereinrichtung über ein Kommunikationsmodul bzw. eine Kommunikationsschnittstelle verfügt, beispielsweise einen Bluetooth- oder WLAN-Sender/Empfänger, über welchen sie mit einer Maschinensteuerung der Tischkreissäge verbunden ist. So wäre es dann beispielsweise möglich, dass die Tischkreissäge nur dann in Betrieb genommen werden kann, wenn die Schiebefläche 1 und die Niederhaltefläche 2 des Schiebestocks 3 plan am Werkstück an- bzw. aufliegen.Furthermore, the push stick 3 has an LED 5, which serves as a signaling device 5 which, in response to whether the detection device 4 formed by the two micro-probes 4 detects the plane contact of the sliding surface 1 and the hold-down surface 2 on the workpiece or not, a Plananlage- Signal indicates, which signals whether the sliding surface 1 and the hold-down surface 2 flat against the workpiece or not. In the exemplary embodiment, the LED 5 is therefore illuminated when the system is flat. Of course, it could also be the case that the LED 5 lights as a warning light when there is no mutual plan system. Furthermore, the signaling device 5 could alternatively or in addition to the LED 5 also have a different signal generator, such as an acoustic signal generator or a vibration alarm. Furthermore, it would be conceivable that the signaling device has a communication module or a communication interface, for example a Bluetooth or WLAN transmitter / receiver, via which it is connected to a machine control of the table saw. So it would be possible, for example, that the table saw can only be put into operation when the sliding surface 1 and the hold-down surface 2 of the sliding stick 3 plan on the workpiece or rest.

Figur 3 zeigt den Schaltplan des Schiebestocks 3 und damit die elektrische Verbindung der Mikrotaster 4 mit der LED 5 und der als Stromversorgung vorgesehenen Knopfzelle 7, welche in eine in der Figur 1 gezeigten Knopfzellenhalterung 8 eingesetzt ist. Die beiden Mikrotaster 4 sind dabei als UND-Gatter geschaltet, d. h. die LED 5 leuchtet nur, wenn beide Mikrotaster 4 betätigt werden, wenn also beide Flächen 1, 2 plan auf dem Werkstück aufliegen. Somit zeigt die leuchtende LED 5 dem den Schiebestock 3 benutzenden Maschinenbediener an, dass das Werkstück mit größtmöglicher Sicherheit dem Sägeblatt der Tischkreissäge zugeführt werden kann. FIG. 3 shows the circuit diagram of the push stick 3, and thus the electrical connection of the micro-probe 4 with the LED 5 and provided as a power button cell 7, which in a in the FIG. 1 shown button cell holder 8 is inserted. The two micro-switches 4 are connected as an AND gate, ie, the LED 5 lights only when both micro-switches 4 are actuated, so if both surfaces 1, 2 rest flat on the workpiece. Thus, the luminous LED 5 indicates to the operator using the push stick 3 that the workpiece can be fed to the saw blade of the table saw with the greatest possible safety.

Um das von den beiden Mikrotastern 4 abgegebene Plananlage-Signal auch für empfindliche Signalverarbeitungseinrichtungen nutzen zu können, beispielsweise an der Maschinensteuerung der Kreissäge, ist es dabei vorteilhaft, die Mikrotaster 4 zu entprellen. Dies kann beispielsweise durch einen Tiefpassfilter, ein Flip-Flop oder durch einen Mikrocontroller mit entsprechender Software geschehen.In order to be able to use the plane contact signal emitted by the two micro-buttons 4 also for sensitive signal processing devices, for example on the machine control of the circular saw, it is advantageous to debounce the micro-push-buttons 4. This can be done for example by a low-pass filter, a flip-flop or by a microcontroller with appropriate software.

Abwandlungen und Modifikationen der gezeigten Ausführungsformen sind möglich, ohne den Rahmen der Erfindung zu verlassen.Modifications and modifications of the illustrated embodiments are possible without departing from the scope of the invention.
