In to reel 9 status detection, we have adopted infrared electrooptical device.Owing to open breach on the reel 9 by the angle five equilibrium, if therefore reel rotates, when the barbed portion on the reel is passed through the light-emitting zone of electrooptical device, the infrared light that the electrooptical device luminous component sends will arrive receiving-member by wheel, make the electrooptical device output low level.And when the other parts of reel 9 turn over, it will stop infrared light, make high level of the final output of electrooptical device.As long as reel constantly rotates, will form the level that constantly changes, just a pulse signal like this at the output of electrooptical device.And if reel 9 stops operating, then infrared ray or by breach does not perhaps pass through, and therefore infrared receiving terminal will export one or height, or low fixed level.
Next, we need signal is carried out shaping and collection.By appended principle as can be seen: nine pin positions on corresponding the embroidery machine, we need gather and handle nine road signals.But this nine road signal is not all to work simultaneously, but at synchronization, has only one of them in work.Just it is just started working when corresponding this pin position signal comes.In view of the situation, we have adopted a kind of gate circuit that has shaping feature to come it is gathered.Its effect has two, and the one, shaping is carried out in the pulse of electrooptical device; The 2nd, as long as the arbitrary road output pulse in nine road electrooptical devices of front, it also will export pulse, if pulse is not all exported in front nine tunnel, it will export a fixed level.
The result that will gather delivers in the circuits for triggering 83 of back again.The function of these circuits for triggering is: if there is pulse the front, just reel 9 is when changeing, and it will export high level, and keeps a period of time; If in a period of time, still there is not pulse to come (just bottom line has broken, in reel 9 does not change), it is with output low level.Like this, we become the level signal of a correspondence just the disconnected and continuous situation of bottom line.
Carry out anti-phase with 84 pairs of signals of transistor amplifier again and driving, the signal after driving and original detection signal of reaching the standard grade are sent into the CPU processing through the burn out detection plate together.After CPU detects disconnection signal, will make respective reaction, as: embroidery machine stops, and disconnect lamp 10 is bright, head electromagnetic actuation etc.
So far, the bottom line testing is finished.
