Problems solved by technology

[0005] The problem in this safety device may be that the operator can be brought into a position in such a way that although the RFID system still signals the closed position of the safety door, the blocking bolt still comes out of the receiving part of the operator.

Embodiment Construction

[0034] Figures 1 to 3 Various embodiments of a safety device 1 according to the invention are shown, which have a safety switch 2 and an actuator 3 that is movable relative to the safety switch 2 .

[0035] The safety device 1 is used, for example, to secure a safety door as an access to a danger zone. The operator 3 can be arranged on the protective door, and the safety switch 2 can be arranged on the frame limiting the opening of the door.

[0036] On the one hand, the closed position of the protective door is controlled by the safety device 1 , wherein the protective door is in its closed position when the actuating element 3 is in the corresponding closed position on the safety switch 2 . Furthermore, the locking of the safety door in its closed position is brought about by the safety device 1 .

[0037] according to Figures 1 to 3 The exemplary embodiment of FIG. 2 shows the actuator 3 in its closed position, in which the actuator 3 is opposite the safety switch 2 . ...

Abstract

The invention relates to a safety device (1) having a safety switch (2) and an actuator (3) arranged movably relative to the safety switch. A transponder (5) is arranged in the operator (3) and a reading unit (4) is arranged in the safety switch (2). The closed position of the operator (3) is controlled by sensing the transponder signal of the transponder (5) in the read unit (4). The safety switch (2) has a blocking element (6) with an influencing element (12). The manipulator (3) has a sensor (11) coupled to the transponder (5). In the closed position of the actuator (3), the blocking element (12) can be inserted into the receptacle (7) of the actuator (3). This results in a blocking of the manipulator (3). This blocking is controlled in that the influencing element ( 12 ) is in the area of ​​influence of the sensor ( 11 ) only when the blocking element ( 6 ) is introduced into the receptacle ( 7 ). The sensor generates a sensor signal by means of which the transponder signal sent by the transponder (5) is changed. The changed transponder signal is sensed in the read unit (4).

Description

technical field [0001] The invention relates to a safety device. Background technique [0002] Such a safety device comprises a safety switch and an operator which is arranged movably relative to the safety switch. Safety devices constructed in this way are generally used in the field of safety technology. An example of such a use in the field of safety technology is an access safety device to a hazardous area, in which the access can be closed with a protective door. In this case, the operator is typically arranged on the guard door, while the safety switch is arranged on the frame structure delimiting the access. [0003] Known safety switches have an RFID system with a transponder integrated in the operator and a reading unit integrated in the safety switch. The closing position of the protective door can be controlled by this RFID system. Only when the door is in the closed position is the transponder in the operator spatially assigned to the read unit in the safety ...
