As shown in Figure 3, the counting circuit of the present embodiment comprises U1 ~ U6 six CD40110 chips and SEG1 ~ SEG6 six charactron 5101AS, and 42 360 Ω resistance R1 and 2 10k Ω resistance R2, and its circuit connecting relation is as figure.The Count+_1 end of counting circuit and Count+_2 end connect the normally opened contact S1-1 two ends of the time relay S1 of above-mentioned steel billet direction of transfer recognition device respectively, and the Count-_1 end of counting circuit and Count-_2 end connect the normally opened contact S2-1 two ends of the time relay S2 of above-mentioned steel billet direction of transfer recognition device respectively.
When the steel billet auto-counter of the present embodiment is installed, phototransistor RG1 near heating furnace direction, phototransistor RG2 near rolling system direction, when namely ensureing that steel billet forward transmits first after phototransistor RG1 through phototransistor RG2.Phototransistor RG1 and RG2 is for detecting steel billet through out-of-date sent high light.
In conjunction with reference to figure 2, transport through for steel billet forward, the course of work following (in the technical program, the time relay chooses to obtain electric time lagged type or power cut off delay type, and the present embodiment is described for the power cut off delay type time relay) of the steel billet auto-counter of the present embodiment:
Phototransistor RG1 do not receive illumination namely do not sense steel billet arrive in, NPN type triode VT11 and PNP type triode VT12 conducting, relay K 1 coil obtains electric, and its normally closed contact K1-1 disconnects, time relay S1 coil must not be electric, and its normally opened contact S1-1 disconnects; In like manner, time relay S2 must not be electric, and its normally opened contact S2-1 disconnects.
When there being steel billet to be normally conveyed through steel billet auto-counter, first steel billet front end reaches phototransistor RG1, phototransistor RG1 receives the light that steel billet sends, the resistance of phototransistor RG1 declines, cause a point drops, so NPN type triode VT11 ends, then resistance R11, the circuit of R12 and NPN type triode VT11 composition disconnects, PNP type triode VT12 also ends, then relay K 1 coil losing electricity, its normally closed contact K1-1 closes, so time relay S1 coil obtains electric, its normally opened contact S1-1 closes, the normally closed contact S1-2 of the time relay S1 in time relay S2 wire loop disconnects, so, phototransistor RG2 is reached after steel billet front end moves the distance of phototransistor RG1 to RG2, when phototransistor RG2 receives the light that steel billet sends, S2 coil is " locked " and can not obtains electric, its normally opened contact S2-1 is failure to actuate.When phototransistor RG1 is left in steel billet rear end first, relay K 1 coil obtains electric, its normally closed contact K1-1 disconnects, time relay S1 coil losing electricity, disconnect after the setting delay time of its normally opened contact S1-1 elapsed time relay S1, closed after the setting delay time of its normally closed contact S1-2 elapsed time relay S1, this setting delay time regulates according to steel billet transfer rate, ensure that steel billet transmitting range is greater than the distance of phototransistor RG1 to RG2 in this setting delay time, therefore before also not leaving phototransistor RG2 after phototransistor RG1 is left in steel billet rear end, normally closed contact S1-2 still remains open state, the normally closed contact K2-1 of relay K 2 is made still to be in closure state even if also do not leave phototransistor RG2 due to steel billet rear end, S2 coil still keeps being " locked " and can not obtaining electric, its normally opened contact S2-1 keeps being failure to actuate.
When steel billet oppositely transports through, the course of work of the steel billet direction of transfer recognition device of the present embodiment and said process, according to the first sensor circuit and the second sensor circuit, the first executive circuit and the second executive circuit full symmetric, have not just repeated at this.
Known by the above-mentioned course of work, the normally opened contact S1-1 of original state time relay S1 and the normally opened contact S2-1 of time relay S2 is all in off-state; When steel billet forward transports through, the normally opened contact S1-1 of time relay S1 closes, and the normally opened contact S2-1 of time relay S2 remains open; When steel billet oppositely transports through, the normally opened contact S2-1 of time relay S2 closes, and the normally opened contact S1-1 of time relay S1 remains open; Steel billet is complete pass through after, restPose.
During the steel billet auto-counter work of the present embodiment, the course of work of counting circuit transports through for steel billet forward, and in conjunction with reference to figure 3, the course of work is as follows:
The Count+_1 end of counting circuit and Count+_2 hold the normally opened contact S1-1 two ends of tie-time relay S1, and when Count+_1 and Count+_2 conducting, represent that steel billet forward passes through, CD40110 chip carries out adding counting; The Count-_1 end of counting circuit and Count-_2 hold the normally opened contact S2-1 two ends of tie-time relay S2, when Count-_1 and Count-_2 conducting, expression steel billet back through, CD40110 chip carries out subtracting counting." Clear " end in counting circuit can connect switch, realizes counter O reset.Charactron 5101AS shows current count value.
It should be noted that above cited embodiment is only specific embodiment of the utility model.Obvious the utility model is not limited to above embodiment, and the similar change thereupon made or distortion are that those skilled in the art can directly draw from content disclosed in the utility model or be easy to just associate, and all should belong to protection domain of the present utility model.
