Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Automatic feeding device embodiment
Automatic feeding device comprises feeding mechanism, feeding motor, and the control of drawing-in device is mainly reflected in to the control to feeding motor.Be respectively as shown in Figure 1 and Figure 2 main circuit and the control circuit of the utility model feeding motor.
Main circuit mainly comprises feeding motor M1, its control contactor KM1, overcurrent protector FR1, circuit breaker Q S1, the phase-sequence detector KA1 of isolating switch outlet.
Control circuit mainly comprises:
The startup branch road of feeding motor, comprises the coil of feeding motor control contactor KM1 and a normally opened contact of starting contactor KA3 that string is established, and the coil of a first timing relay KT2 in parallel with feeding motor control contactor KM1.At KM1 coil, obtain when electric, KT2 coil also simultaneously electric, so as other embodiment, KM1 coil and KT2 coil also can adopt cascaded structure.
The delay power branch road of approach switch SQ1, comprises the second time closing contact (KT2:1,3) of approach switch SQ1 and first timing relay of series connection.
Approach switch time delay branch road, comprises the coil of the second timing relay KT3 of energising when closed in the second time closing contact of the first timing relay (KT2:1,3); As Fig. 2, in the delay power branch road of approach switch SQ1, string is provided with the coil of an auxiliary reclay KA2, connect with the coil of the second timing relay KT3 in the contact of this auxiliary reclay KA2, to realize coil energising when closing contact (KT2:1,3) is closed of above-mentioned KT3.
Disorderly closedown branch road, comprises the coil of starting contactor KA3 and a time delay break contact (KT3:5,8) of the second timing relay of series connection; As other embodiment, can add various malfunctioning nodes, as shown in Figure 2, the corresponding contact of phase-sequence detector KA1 and overcurrent protector FR1, and a limit switch SQ2 who detects feeding motor fault all goes here and there and is located in described disorderly closedown branch road.
Warning branch road, comprises a normally closed contact and an alarm of the starting contactor (KA3) of series connection.
The utility model is divided into automatically and manual two kinds of patterns, and two kinds of patterns are corresponding with the startup branch road of feeding motor; The startup branch road of feeding motor comprises manual part and automatic part in parallel, and manual part, automatic part respectively correspondence are provided with change-over switch SA1, and manually partly string is provided with starting switch S1, and automatic part string is provided with delay switch KT1.
As also comprised a Switching Power Supply G in the control circuit of Fig. 2, be used to the direct current device power supplies such as SQ1, KA2, KA3.
The course of work is described in detail as follows:
Under manual mode: by the indicating positions sensing " manually " of SA1 and by QS1, now KA1 work, relay indicating light lights respectively, and 5,6 contacts of KA1 are become the while close point from battle, and 7,8 contacts will become battle from close point.
QS3 is closed, and because 5,6 contacts of KA1 are closed respectively, the contact of 95,96 contacts of FR1,5,8 contacts of KT3, SQ2 is normally closed, and KA3 starts working, and 5,9 contacts of KA3 are become close point from normal battle.
Press start button S1, due to 5,9 points of KA3,11,12 points of S2,13,14 closures of SA1, KM1, KT2 starts working, M1 entry into service.After reaching the time delay of KT2 setting, 1,3 of KT2 are become close point from normal battle.
When SQ1 is triggered (and maintenance), KA2 work, 5,9 closings of contact of KA2, KT3 starts working, after reaching the time delay of KT3 setting, 5,8 contacts of KT3, to become battle from normally closed, so KA3 will quit work, 5,9 contacts of KA3 will disconnect, now KT2, KM1 will quit work, and M1 will shut down.HA will start working, and carry out sound and light alarm.
Automatic mode and manual mode are basic identical, and difference is only, do not need manually by S1, and set delay time by KT1, reach setting-up time, KT1 1 and 2 by closure.
About the embodiment of control circuit, because control circuit is completely contained in above-mentioned material loading, drawing-in device, so repeat no more.
