Abstract

The safety mechanism for an emergency line breaker in machines and manufacturing systems prevents undesired switching off. The emergency line breaker (7) is surrounded by a circular projecting protective ring (2). The diameter of this ring (2) is such that it is possible to switch off the machine if desired by the fist or elbow. The protective ring (2) is preferably see-through and divided into two differently coloured areas (5,6) corresponding to the on and off states. The on and off states may be lit by different coloured lamps or can be indicated by an acoustic output.

Description

Die Erfindung betrifft eine Sicherheitsvorrichtung für Not­ ausschalter bei Maschinen- und Fertigungsanlagen zur Vermei­ dung unerwünschter Abschaltungen.The invention relates to a safety device for emergency switch for machine and manufacturing systems to avoid unwanted shutdowns.

Maschinen und Fertigungslinien sind an verschiedenen Stellen durch Notausschalter abgesichert. Es kommt immer wieder vor, daß diese zum Beispiel durch Aufstützen und Anlehnen an die Maschinen unbeabsichtigt ausgelöst werden. Ein ungewolltes Abschalten einer Fertigungslinie bedeutet meist einen großen Schaden, besonders wenn die Linie nicht innerhalb kürzester Zeit wieder angefahren wird. Die üblichen Mittel zur Vermei­ dung, wie Verbote, Hinweise und Absperrungen sind unzurei­ chend.Machines and production lines are in different places secured by an emergency stop switch. It always happens that, for example, by supporting and leaning against the Machines are triggered unintentionally. An unwanted one Shutting down a production line usually means a big one Damage, especially if the line is not within shortest Time is started again. The usual means of avoidance such as bans, notices and barriers are inadequate chatting.

Aufgabe der vorliegenden Erfindung ist es daher, eine Schutz­ vorrichtung für Notausschalter bei Maschinen und Fertigungs­ anlagen zu schaffen, durch die eine unbeabsichtigte Betäti­ gung vermieden wird.The object of the present invention is therefore to provide protection Device for emergency stop switches in machines and manufacturing to create systems through which an unintended actuation is avoided.

Zur Lösung dieser Aufgabe wird die Sicherheitsvorrichtung gemäß der Erfindung derart ausgebildet, daß der Notausschal­ ter von einem ihn überragenden kreisförmigen Schutzring umge­ ben ist, dessen Durchmesser so dimensioniert ist, daß eine gewünschte Abschaltung per Faust oder Ellbogen möglich ist.To solve this problem, the safety device formed in accordance with the invention such that the emergency stop ter of a circular protective ring towering over him ben, whose diameter is dimensioned so that a desired switch-off by fist or elbow is possible.

Durch diese Maßnahmen kann trotz eines Schutzes vor unbeab­ sichtigter Betätigung eine gewollte Auslösung weiterhin in einfacher Weise erfolgen.Through these measures, despite protection against unavoidable when actuated, a desired release continues in done easily.

Eine weitere Verbesserung ergibt sich wenn der Betriebszu­ stand des Notausschalters direkt vor Ort am Schalter ersicht­ lich ist, da dann in den meisten Fällen wieder kurzfristig angefahren werden kann und der Schaden durch den Stillstand begrenzt wird. Eine solche Anzeige kann auf einfache Art durch mechanisch/optische Weise beispielsweise durch unter­ schiedliche Farbgestaltung der Aus- und Einschaltbereiche, bei durchsichtigem Sicherheitsring über die Stellung des Auslöseknopfes erfolgen oder auch durch optisch/elektrische oder akustisch/elektrische Anzeige.A further improvement results when the company closes stand of the emergency stop switch directly on site at the counter is, since then in most cases again at short notice can be started and the damage from the standstill  is limited. Such a display can be done in a simple manner by mechanical / optical way, for example by under different colors of the switch-on and switch-on areas, with a transparent safety ring about the position of the Trigger button done or by optical / electrical or acoustic / electrical display.

Anhand des Ausführungsbeispiels nach der Figur wird die Er­ findung näher erläutert. Sie zeigt ein Schaltergehäuse 4, aus dem der Notausschalter 7 herausragt. Er trägt an seiner Ober­ seite den Auslöseknopf 1, der in der Figur im Betriebszustand mit durchgezogener Linie dargestellt ist. Wird auf den Auslöseknopf 1 Druck ausgeübt, so rastet er in die Ausstel­ lung - die strichpunktiert angedeutet ist - ein und kann erst durch eine Drehbewegung 3 wieder entriegelt werden. Um ein ungewolltes Auslösen des Notausschalters zu vermeiden ist um den Notausschalter der Schutzring 2 angebracht, der so dimen­ sioniert ist, daß er über den Notausschalter vorsteht und zugleich einen Durchmesser aufweist, daß noch bequem mit der Faust oder dem Ellbogen eine Betätigung erfolgen kann. Die unterschiedliche Stellung des Notausschalters kann optisch dadurch angezeigt werden, daß entweder der Schutzring durch­ sichtig ausgebildet und zusätzlich in Bereiche 5, 6 einge­ teilt ist, die unterschiedliche Farben, beispielsweise grün im eingeschalteten und rot im ausgeschalteten Zustand, auf­ weisen. Es kann aber auch der Auslöseknopf selbst je nach Schaltzustand rot oder grün aufleuchten bzw. durch zwei am Schaltgehäuse befestigte mit unterschiedlicher Farbe ausge­ statteten Lämpchen der Schaltzustand des Notausschalters an­ gezeigt werden oder es besteht die Möglichkeit, durch ein akustisches Signal auf den Aus-Zustand des jeweiligen Not­ schalters hinzuweisen.Based on the embodiment of the figure, the invention is explained in more detail. It shows a switch housing 4 from which the emergency stop switch 7 protrudes. It carries on its upper side the release button 1 , which is shown in the figure in the operating state with a solid line. If pressure is exerted on the release button 1 , it snaps into the exhibition - which is indicated by dash-dotted lines - and can only be unlocked again by a rotary movement 3 . In order to avoid an unwanted triggering of the emergency stop switch, the protective ring 2 is attached to the emergency stop switch, which is dimensioned such that it protrudes beyond the emergency stop switch and at the same time has a diameter that can still be actuated conveniently with the fist or elbow. The different position of the emergency stop switch can be optically indicated by the fact that either the protective ring is clearly formed and additionally divided into areas 5 , 6 , which have different colors, for example green when switched on and red when switched off. However, depending on the switching status, the trigger button itself can light up red or green, or the switching status of the emergency stop switch can be indicated by two lamps attached to the switch housing with different colors, or there is the possibility of an acoustic signal to indicate the OFF status of the to point out the respective emergency switch.
