Abstract
Description
Die Erfindung betrifft eine Sicherheitseinrichtung für Werkzeugmaschinen gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren gemäß dem Oberbegriff des Anspruchs 6.The The invention relates to a safety device for machine tools according to the preamble of claim 1 and a method according to the preamble of the claim 6th
Aus Produktion oder Werkstätten ist bekannt, dass bei Werkzeugmaschinen mit schnell drehenden Teilen besondere Arbeitsschutzmaßnahmen eingehalten werden müssen. So gibt es beispielsweise berufsgenossenschaftliche Bestimmungen bzw. Musterbetriebsanweisungen, nach denen die Bedienung von Bohrmaschinen nur ohne Handschuhe erfolgen darf, da sich ein Handschuh im Bohrfutter/Werkzeug verfangen und es so zu Arbeitsunfällen kommen könnte. Andererseits sind Handschuhe für andere Tätigkeiten, wie beispielsweise bei der Verwendung von scharfkantigen Werkstücken oder Schneidwerkzeugen, vorgeschrieben. Bei einem schnellen Wechsel zwischen den verschiedenen Arbeiten kann es daher dazu kommen, dass der Werker vergisst, die Handschuhe an- bzw. auszuziehen.Out Production or workshops is known to be used in machine tools with fast-rotating parts, special occupational safety measures complied with Need to become. For example, there are Berufsgenossenschaftliche Determinations or model operating instructions according to which the operation of drills may only be done without gloves, as a Glove caught in the drill chuck / tool and so come to work accidents could. On the other hand, gloves are for others Activities, such as when using sharp-edged workpieces or cutting tools, prescribed. For a quick change between the different jobs It can therefore happen that the worker forgets the gloves put on or take off.

Es ist Aufgabe der Erfindung, ein Verfahren und eine Sicherheitseinrichtung für Werkzeugmaschinen dahingehend weiterzuentwickeln, dass die Arbeitssicherheit zuverlässig erhöht ist.It Object of the invention, a method and a safety device for machine tools to further develop that the safety at work is reliably increased.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The Task is according to the invention with the features of claim 1.
Vorteilhafte Ausgestaltungen ergeben sich aus den Merkmalen der Unteransprüche.advantageous Embodiments result from the features of the subclaims.
Erfindungsgemäß ist vorgesehen, dass eine Sicherheitseinrichtung eine Sende- und Empfangseinheit umfasst, deren Auswerteschaltung ein Signal erzeugt, sobald ein Werker mit seinem Handschuh, der erfindungsgemäß mit einem Signaltransponder ausgerüstet ist, in einen von der Sende- und Empfangseinheit definierten Kontrollbereich gelangt. Zur laufenden Überwachung der Funktionsfähigkeit der Sicherheitseinrichtung ist ein Kontrolltransponder vorgesehen, der permanent mit der Sende- und Empfangseinheit in Verbindung steht. Dabei überwacht die Sende- und Empfangseinheit zwei verschiedene Kennungen, von denen eine auf den Kontrolltransponder und die andere auf den Signaltransponder am Handschuh abgestimmt ist. Durch die laufende Überwachung der Funktionsfähigkeit der Sicherheitseinrichtung kann es zu keiner fehlerbehafteten Abschaltung der Werkzeugmaschine kommen. Gerade bei Bohrmaschinen ist es besonders gefährlich, diese mit Handschuhen zu bedienen. Kommt ein Werker mit seinen Handschuhen in den Kontrollbereich, registriert die Sende- und Empfangseinheit den am Handschuh befestigten Signaltransponder mit seiner speziellen Kennung. Die Auswerteschaltung erzeugt daraufhin ein adäquates Signal, das weiter verarbeitet werden kann.According to the invention provided that a safety device a transmitting and receiving unit includes, whose evaluation circuit generates a signal as soon as Worker with his glove according to the invention with equipped with a signal transponder, in one of the Transmitting and receiving unit defined control area. For continuous monitoring of functionality the safety device is provided with a control transponder, which is permanently connected to the transmitting and receiving unit. The transmitting and receiving unit monitors two different identifiers, one on the control transponder and the other on the control transponder Signal transponder is matched to the glove. Through the ongoing monitoring the functionality of the safety device can there is no faulty shutdown of the machine tool. Especially with drills, it is particularly dangerous with these Gloves to use. Comes a worker with his gloves into the control area, registers the transmitting and receiving unit the attached to the glove signal transponder with its special ID. The evaluation circuit then generates an adequate Signal that can be processed further.
Vorzugsweise kann das von der Auswerteschaltung erzeugte Signal eine Unterbrechung der Stromzufuhr der Werkzeugmaschine bewirken. Der Vorteil dabei ist, dass die Maschine nicht mehr bedient werden kann, solange der Werker seine Handschuhe trägt. Der Werker muss also die Handschuhe ausziehen und die Maschine manuell wieder in Betrieb nehmen.Preferably the signal generated by the evaluation circuit may be interrupted cause the power supply of the machine tool. The advantage here is that the machine can not be operated as long as the Worker wears his gloves. The worker must therefore the Take off the gloves and put the machine back into operation manually to take.
Es kann vorgesehen sein, dass für die Transponder passive RFID-Transponder eingesetzt werden, da diese günstig in der Anschaffung sind. Von Vorteil dabei ist, dass die Transponder selber nicht senden, so dass keine Stromzufuhr notwendig ist. RFID-Transponder sind sehr klein und daher auch gut integrierbar in Handschuhe.It can be provided that passive for the transponder RFID transponders are used as these are cheap in of the purchase. The advantage here is that the transponder do not send yourself, so no power supply is necessary. RFID transponder are very small and therefore easy to integrate in gloves.
Um eine gegenseitige Beeinflussung von mehreren erfindungsgemäßen Sicherheitseinrichtungen zu vermeiden, sollte sich der Kontrollbereich nur im Rahmen des notwendigen Aktionsradius rund um die Werkzeugmaschinen erstrecken und diesen nicht wesentlich überschreiten.Around a mutual influence of several inventive Safety devices should be avoided, the control area only within the scope of the necessary range of action around the machine tools extend and do not significantly exceed this.
Um metallische Einflüsse auszuschließen, kann vorgesehen werden, die Sende- und Empfangseinheit entsprechend abzuschirmen.Around Excluding metallic influences can be provided to shield the transmitting and receiving unit accordingly.
Neben der Sicherheitseinrichtung selbst ist erfindungsgemäß ein Verfahren zur Sicherheitsabschaltung einer Werkzeugmaschine mit schnell drehenden Teilen, insbesondere eine Bohrmaschine, vorgesehen, bei dem eine Sende- und Empfangseinheit wenigstens zwei Kennungen sendet und empfängt. Die Auswerteschaltung kann je nach detektierter Kennung ein Signal erzeugen, sobald ein Handschuh mit einem Signaltransponder in einen Kontrollbereich der Sende- und Empfangseinheit gelangt. Aus Sicherheitsgründen und zur Kontrolle, ob die Sicherheitseinrichtung zuverlässig arbeitet, steht ein Kontrolltransponder permanent mit einer vom Signaltransponder verschiedenen Kennung in Verbindung mit der Sende- und Empfangseinheit.Next the safety device itself is according to the invention Method for safety shutdown of a machine tool with fast rotating parts, in particular a drill, provided, in which a transmitting and receiving unit has at least two identifiers sends and receives. The evaluation circuit can vary depending on Detected identifier generate a signal as soon as a glove with a signal transponder in a control area of the transmitting and Receiving unit passes. For security reasons and for Checking that the safety device is working reliably, a control transponder is permanently connected to one of the signal transponders different identifier in connection with the transmitting and receiving unit.
