Road, the circuits S11-S21, when either signal circuit disconnects, being responsible for the safety relay of monitoring emergency stop switch will act,
The internal circuits 24-23, the circuits 34-33, the circuits 14-13 will be switched off.Signal is fed back in addition to the circuits 14-13 on these circuits
PLC does signal and shows outer, and 24-23, the circuits 34-33 will make third intermediate relay KA3, KA4 lose power supply, to make KA3,
Normally-closed contact on KA4 disconnects.The normally-closed contact of KA3, KA4 will be sealed in safety relay signal output end to safety door,
Control KA7, KA8 intermediate relay finally acted on.That is, when emergency stop switch 9 is taken, dot matrix marking equipment will be unable to move
Make, the motions such as servo-driver can not also act, and from achieving the purpose that safeguard protection, and only, associated loop signal is being just
Chang Hou can just be reset, and equipment could continue to produce.
Therefore, when the protection grating 5 of the dot matrix marking equipment either safety door that is blocked is opened or 9 quilt of emergency stop switch
When taking, the executing agency of dot matrix marking equipment, telecontrol equipment can not act.Also, the action of relevant device stops, and
The instruction not sent out by control elements such as PLC or PC acts relevant device stopping in equipment source, this situation
Under, even if PLC, PC of dot matrix marking equipment break down, or by the case of unconscious shielding, associated safety protective loop
Also it can work normally, ensure the processing safety of whole dot matrix marking equipment.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
