Component mounting machine and safety device thereof

摘要

The safety device comprises an opening/closing cover 9, 12 which shuts off a takeout part 8c and an accommodating part 8a of a component feeder unit 8 from each other and which has a sensor for detecting a closed state, the component feeder unit 8 comprising the component accommodating part 8a, a feed-out part 8b and the takeout part 8c, and sensors 18, 19 for transmission through voids 81 common to the plurality of set component feeder units 8. Upon a detection of any one of the sensors during the operation of the machine, the machine is halted. For replacement of the component feeder units 8, a changeover switch 20 is pressed, by which the detecting function is halted for a specified time period. Thus, a safety device which allows the component feeder units 8 to be replaced even during the operation of the machine can be obtained.
