Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Automatic charging device embodiment
Automatic charging device comprises feed mechanism, drives the material loading motor of said mechanism, and the control of feeding device is mainly reflected in to the control to material loading motor.Be respectively as shown in Figure 1 and Figure 2 main circuit and the control circuit of the utility model material loading motor.
Main circuit mainly comprises material loading motor M 2, its control contactor KM2, overcurrent protector FR2, circuit breaker Q S2, the phase-sequence detector KA4 of isolating switch outlet.
Control circuit mainly comprises:
The startup branch road of material loading motor M 2, comprises the coil of material loading electric motor control contactor KM2 and a normally opened contact of starting contactor KA3 that string is established.
Approach switch time delay branch road, comprises the coil of timing relay KT3 of an energising when approach switch SQ1 triggers.Approach switch SQ1 connects with the coil of an auxiliary reclay KA2, connects with the coil of described timing relay KT3 in the contact of this auxiliary reclay KA2.
Disorderly closedown branch road, comprises the coil of starting contactor KA3 and a time delay break contact of timing relay KT3 of series connection.As other embodiment, can add various malfunctioning nodes, as shown in Figure 2, the corresponding contact of phase-sequence detector KA4, overcurrent protector FR2 is all gone 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 QS2 is closed, now KA4 work, relay indicating light lights respectively, and 5,6 contacts of KA4 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 KA4 are closed respectively, the normally closed KA3 in contact of 95,96 contacts of FR2,5,8 contacts of KT3, SQ2 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, KM2 starts working, M2 entry into service.
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, will become battle from normally closed, so KA3 will quit work, 5,9 contacts of KA3 will disconnect, 4,12 by closure, and now KM2 will quit work, and M2 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.
The utility model is set the time that starts material loading, and the in the situation that of energising, after time of arrival, three phase electric machine is started working, by driving soft auger to start material loading.Feed link piping flows on Measuring glass or feeder, after material is full.In the continuous 5S of sensor, material detected and will disconnect three-phase electricity, three phase electric machine is quit work.Realize light current and control forceful electric power, three phase electric machine this material loading that quits work just finishes.Delay switch has 8 groups of timers, can meet the material loading at different time.
About the embodiment of control circuit, because control circuit is completely contained in said apparatus, so repeat no more.
