Brief description of the drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Specific embodiment

As shown in figure 1, a kind of new cigarette machine mouth rod supply electromagnetic clutch drive circuit described in the utility model, bag Include Programmable Logic Controller 1, the first relay 2, the second relay 3, electromagnetic clutch Y, piezoresistor R, diode V, electric capacity C With inductance approach switch B, the coil K3 of the coil K2 of the first relay 2 and the second relay 3 is connected on programmable control respectively In two output loops of device processed 1, i.e. one end of the coil K3 of one end of the coil K2 of the first relay 2 and the second relay 3 The line of two output ends of Programmable Logic Controller, the other end of the coil K2 of the first relay 2 and the second relay 3 is connected respectively The other end for enclosing K3 connects the common port of Programmable Logic Controller.One end connection 24V of the normally-closed contact K21 of the first relay 2 is straight Stream power supply, the positive pole of the other end connection diode V of the normally-closed contact K21 of the first relay 2, the normally opened of the first relay 2 touches One end connection 32V AC powers of point K22, the positive pole of the other end connection diode V of the normally opened contact K22 of the first relay 2, The negative pole of diode V passes sequentially through the coil connection dc source of the normally opened contact K31 and electromagnetic clutch Y of the second relay 3 Negative pole, the negative pole of diode V also connects DC power cathode by electric capacity C, and piezoresistor R is connected in parallel on electromagnetic clutch Y's Coil two ends, inductance approach switch B is arranged on the station side of electromagnetic clutch Y, and the output end of inductance approach switch B connects Connect the input of Programmable Logic Controller 1.

Operation principle of the present utility model is：During cigarette machine startup optimization, the coil K2 and the second relay of the first relay 2 The coil K3 of device 3 provides 24V DC voltages by the output end of Programmable Logic Controller simultaneously, then the normally-closed contact of the first relay 2 K21 disconnects, normally opened contact K22 closures, while the normally opened contact K31 closures of the second relay 3,32V AC powers are by two poles Pipe V and electric capacity C power to electromagnetic clutch Y.Due to diode V and the collective effect of electric capacity C, according to rectification circuit principle, electricity Hold the DC voltage that 32*1.414=45V is produced on C, i.e. the coil two ends of electromagnetic clutch Y added with 45V DC voltages, it is now electric The torque of magnet clutch Y is about 180Nm, and resistance can be overcome accurately to engage in place.When setting time delay using Programmable Logic Controller 1 Between, 45V DC voltages maintain 800ms after Programmable Logic Controller 1 control the first relay 2 coil K2 dead electricity, then first after The normally opened contact K22 of electrical equipment 2 is disconnected, and normally-closed contact K21 closures, 24V dc sources are supplied by diode V to electromagnetic clutch Y Electricity, now the torque of electromagnetic clutch Y be about 100Nm.If cigarette machine is shut down, the supply clutch of technological requirement mouth rod is disengaged, then Programmable Logic Controller 1 controls the coil K3 dead electricity of the second relay 3, then the normally opened contact K31 of the second relay 3 disconnects, electromagnetism Unnecessary electric energy on the coil of clutch Y is discharged by piezoresistor R, will not be to whole equipment control system and related electric Element produces impact with interference.

The operating position of inductance approach switch B monitoring electromagnetic clutch Y of the present utility model, in the first relay 2 After the coil K3 energizations 2s of coil K2 and the second relay 3, if inductance approach switch B does not sense electromagnetic clutch Y In place, then the control of Programmable Logic Controller 1 cigarette machine is shut down, and provides warning message and abort situation in man-machine interface for action.Together Reason, when the coil K3 dead electricity of the second relay 3, when technological requirement electromagnetic clutch Y returns to initial position, if inductance type is close opening Close B and sense electromagnetic clutch Y still in the location of workpiece, then cigarette machine can not normally start, while Programmable Logic Controller 1 is in people Warning message and abort situation are provided on machine interface.Software program involved by Programmable Logic Controller of the present utility model 1 is this The known technology in field, not within the protection domain of the application.
