Embodiment:
The present invention is described in detail below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4.
But a kind of single interlocking line block diagram of motor forward/backward rotation timing automatic conversion operation control as shown in Figure 1, motor forward/backward rotation control main loop circuit figure as shown in Figure 2, the on-delay time relay self is inner one group often opens, the normally-closed contact connection layout as shown in Figure 3, motor forward/backward rotation control loop circuit diagram is as shown in Figure 4.In Fig. 1, timing control unit is made of the on-delay time relay, the motor forward/backward rotation control loop is realized with the routine techniques means, it is controlled switching on and off of different contactor main contactss and realizes that control Motor Control major loop prograde circuit or circuit for reversing are switched on or switched off, single interlock circuit by a group of the on-delay time relay self inside often open, normally-closed contact forms.Fig. 2 is conventional motor forward/backward rotation control main loop circuit.Fig. 3 be the present invention require the on-delay time relay self inner one group should have often open, the structure of normally-closed contact, wherein side a and b maintains static, the C end is common port and removable, C holds or shift to the A end makes A-C be communicated with (this moment, B-C disconnected), C holds or shift to the B end makes B-C be communicated with (this moment, A-C disconnected), the situation that A-C and B-C are communicated with simultaneously will not occur, single interlock circuit of the presently claimed invention by one group shown in Figure 3 often have open, the structure of normally-closed contact consists of.Fig. 4 is motor forward/backward rotation control loop circuit diagram, and single interlock circuit just is included among Fig. 4.But a kind of single interlocking line of motor forward/backward rotation timing automatic conversion operation control is made of Fig. 2 and Fig. 4.
In Fig. 4, SB1 and SB2 are push-button switches, and KM1 and KM2 are contactor coils, KM3 is relay coil, and KT1 and KT2 are the on-delay time relay coils, and FU1 is fuse, FR is the control contact of thermal relay among Fig. 2, and physical circuit connects as follows: see that summary of the invention is described.
The specific works mode is as follows:
Such as Fig. 2, shown in Figure 4, suppose KM1(KM2) motor forward (counter-rotating) during the main contacts adhesive of contactor, before actuating motor rotating operation, set first the delay time of time relay KT1 and KT2.Slightly stop a moment after pressing the button SB2, then unclamp the SB2 button, close in the KM3-1 of KM3 relay, two contacts of KM3-2, the KM3 relay coil keeps energising, and contactor KM1 coil electricity, motor begin the forward power supply, KT1 coil electricity and KT1 begin regularly, the KM1-1 contact disconnects, KT2 coil blackout, KM2 coil blackout; When the KT1 timing then, the KT1-1 contact disconnects first, then KT1-2 closes the contact, the KM1 coil cuts off the power supply first, and then contactor KM2 coil switches on, and motor stops to begin the counter-rotating power supply after the forward power supply, KM1-1 closes the contact, and KT2 coil electricity, KT2 begin regularly; When the KT2 timing then, the KT2-1 contact disconnects first, the KT1 coil blackout also makes KT1 reset to initial condition, the KT1-2 contact disconnects first, and then KT1-1 closes the contact, and the KM2 coil cuts off the power supply first, then the KM1 coil switches on, motor stops to begin the forward power supply after the counter-rotating power supply, and the KM1-1 contact disconnects, and the KT2 coil blackout also makes KT2 reset to initial condition, KT2-1 closes the contact, the KT1 coil is switched on again, and KT1 begins again regularly to repeat the process of front; Motor is constantly carrying out rotating and reverse operation according to KT1 and KT2 timing.When the needs motor is out of service, press the button and slightly stop behind the SB1 a moment, then unclamp the SB1 button and get final product.
In Fig. 4, two contacts of KT1-1 and KT1-2 are serially connected in respectively in the separately branch road of KM1 coil and KM2 coil, because closed simultaneously phenomenon can not occur in KT1-1 and two contacts of KT1-2, see Fig. 3, so KM1 coil and KM2 coil just the simultaneously phenomenon of energising can not occur, therefore, the phenomenon of Motor Control major loop short circuit can not occur all any time, thereby, utilize two contacts of KT1-1 and KT1-2 can realize the interlocked of KM1 coil and KM2 coil electricity is used.
But single interlocking line of a kind of motor forward/backward rotation timing automatic conversion operation control of the present invention except can be used for motor forward/backward rotation timing automatic conversion operation control, also can be used for through simple process the unidirectional operation control of motor.
