Description of drawings
Fig. 1 is the switching circuit schematic diagram of the single signal controlling of induction type.
Embodiment
Embodiment 1:
One, circuit structure and function
Physical circuit is as shown in Figure 1, comprises three parts: power unit, test section and switching circuit portion.
1. power unit
Comprise circuit breaker (DZ1) and Switching Power Supply (KD), Switching Power Supply (KD) connects AC power through circuit breaker (DZ1).Circuit breaker (DZ1) is used to be switched on or switched off power supply.Switching Power Supply is used for alternating current is become direct current, is about to alternating current 220V and becomes direct current 24V (safe voltage), guarantees Electrical Safety.
2. test section
The test section comprises detecting sensor (JK) and signal output relay (KA1); Detecting sensor (JK) is connected in parallel between two outputs of Switching Power Supply (KD), and signal output relay (KA1) is connected in parallel between the middle output and positive source of detecting sensor (JK).Detecting sensor (JK) is responsible for detecting the left and right sides of workpiece, produces a pulse when detecting the right side edge part, makes signal output relay (KA1) accomplish a make and break process.Produce a pulse when detecting workpiece left side edge part once more, make signal output relay (KA1) accomplish make and break process for the second time.
Through the contact of signal output relay (KA1), control follow-up switching circuit.
3. switching circuit portion
Switching circuit portion comprises switch relay (KA2), indicator light (HL), the time relay (KT1) and auxiliary relay (KA3).Switch relay (KA2) is connected in parallel between two outputs of Switching Power Supply (KD) respectively with after the normally opened contact (KA1-1) of the normally-closed contact (KT1-1) of the normally-closed contact (KA3-1) of auxiliary relay (KA3), the time relay (KT1) and signal output relay (KA1) is connected; Indicator light (HL) be connected in parallel between two outputs of Switching Power Supply (KD) after the normally opened contact (KA2-1) of switch relay (KA2) is connected; The time relay (KT1) be connected in parallel between two outputs of Switching Power Supply (KD) after another normally opened contact (KA2-2) of switch relay (KA2) is connected; Auxiliary relay (KA3) is connected in parallel between two outputs of Switching Power Supply (KD) respectively with after another normally opened contact (KA1-2) of the normally opened contact (KT1-2) of the time relay (KT1) and signal output relay (KA1) is connected.Be connected drawing between contact KT1-1 and the KA3-1 between the normally opened contact (KA2-1) of single line and indicator light (HL) and switch relay (KA2).Be connected drawing between contact KA1-1 and the KT1-1 between single line and contact KA2-2 and the time relay (KT1) coil.
Two, the basic principle of circuit
Circuit breaker (DZ1) closure, circuit gets into operating state.Workpiece moves with production line from left to right, and detecting sensor (JK) detects workpiece right side edge part back and produces a pulse, makes signal output relay (KA1) accomplish a make and break process.The normally opened contact KA1-1 of relay this moment (KA1) is closed, and it is electric that relay (KA2) coil is got, and its normally opened contact KA2-1 is closed, forms self-hold circuit.KA2-2 is closed simultaneously, and time relay KT1 coil gets electric, and its contact KT1-1, KT1-2 deferred action have so just guaranteed make and break process of relay (KA1) completion, and KA3 must not be electric, and KA2 is kept.Contact by KA2 is controlled, and accomplishes the work of spray mark.
Along with moving from left to right of workpiece, detecting sensor (JK) produces a pulse after detecting workpiece left side edge part once more, makes signal output relay (KA1) accomplish make and break process again one time.Because the deferred action of time relay contact, when making relay (KA1) accomplish make and break process for the second time, relay K A3 gets electric, guarantees that simultaneously KT1 gets.Because it is electric that relay K A3 gets, normally-closed contact KA3-1 breaks off, the KA2 outage.
The core of above-mentioned course of action is exactly the left and right edges part through the detection workpiece, accomplishes the break-make control to switch relay (KA2), thereby accomplishes the mark work of spraying automatically.
