Middle charging control cylinder 24, essence charging control cylinder 25, the cylinder state of concussion charging cylinder 26
Represent with XV001, XV002, XV003 respectively, be to be closed mode when 0, be to be on when 1
State.
Detailed description of the invention:
One, start, PLC brings into operation, and enters init state, it is judged that XV001/XV002/XV003
Whether it is 0 closed mode, if it is, at this moment accompanying drawing 1 cylinder 24,25,26 is in accompanying drawing 3 and initiates
State, obtain electric after, peeling, until Weighing module Weight is shown as 0, at this moment enter the state that feeds greatly；
Two, entering and feed greatly state, XV001/XV002/XV003 obtains electric when being 1 state, accompanying drawing 2
In 24,25,26 cylinders shrink, to accompanying drawing 4 state, at this moment start to feed greatly, until reach to set
When determining weight S1 value, XV001 dead electricity, XV002 obtains electric, and XV003 obtains electric, in accompanying drawing 2 in add
Material controls cylinder 24 and is elongated to initial state, essence charging control cylinder 25, concussion 26, cylinder of charging
Putting motionless, such as accompanying drawing 5, feed at this moment entering state；
Three, until reaching setting weight S2 value time, XV001/XV002/XV003 dead electricity, it is judged that be
No arrival setting weight S3 value, if it is, XV001/XV002/XV003 dead electricity, returns to initial state,
Terminate feed；If it does not, XV001 dead electricity, XV002 dead electricity, XV003 obtains electric, and at 0.5 second
Interior XV003 circulates electric, dead electricity, makes 26 concussion charging cylinders in accompanying drawing 2 produce continuous and adjustable,
Play concussion effect, prevent from material blanking operation produces building bridge, during until reaching setting weight S3 value,
XV001/XV002/XV003 dead electricity, cylinder stop motion, return to initial state, such as accompanying drawing 3.
S3 is target weight setting value, can require to set according to user, reach desired value, cylinder
Quit work, return to initial state.
Fig. 6 is the flow chart of the accuracy control method that feeds intake of described feed precision control device, and Fig. 7 is institute
State the layout of feed precision control device, by the two figure, it can be seen that the flow process signal of operation,
First initializing three groups of cylinders, making three groups of cylinders is all closed mode, and now, three groups of cylinder extruding are medical
Silica gel is flexible coupling so that it is be internally formed taper, the nethermost concussion charging soft company of the locked medical silica-gel of cylinder
Connect；Entering the state that feeds greatly, three groups of cylinders are all turned on, until falling material reaches setting weight S1
During value, middle charging control cylinder is closed, and other two groups of cylinders are opened, and feed in entrance state；Add in
In material state, during until falling material reaches setting weight S2 value, close three groups of cylinders；Pass through electronics
The information that scale returns judges that now whether falling material arrives setting weight S3 value, reaches, and makes three groups of gas
Cylinder returns to initial state, terminates feed；It is not reaching to, controls concussion charging cylinder when fixing interval
Between circulation open, close, until it reaches setting weight S3 value.
