Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, packed polymer automatic charging is mainly by lifting, pushing away bag, cut the process group such as bag, batch turning, output, transmission
Into.Master operation is：1. pocket lifting is arrived by specified altitude assignment by elevator；2. push away bag cylinder is pushed into broken bag mechanism by pocket
In；3. bag cutting mechanism breaks pocket from centre；It is 4. by the upset of batch turning mechanism that dry powder is most；5. empty bag falls on sky automatically
In bag processing unit, by empty bag processing unit by outside empty bag ejecting device；6. polymer falls into big material bin bottom, pass through a left side
Right two conveying worms are transported to two note consor producing lines.
Packed polymer automatic charging device control system is divided into automatically and manually two states.Automatically as operative employee just
Normal charging is used, and is used manually as in debugging and abnormal conditions processing.When automatically controlling, if if elevator is not most lower
End, presses start button, and elevator will first run to bottom, and at this moment, feeding pallet stretches out, and pocket is put into feeding pallet receives
Return, elevator is begun to ramp up.When being re-lowered to bottom Deng elevator, feeding pallet is stretched out, and puts the next bag of people, and feeding pallet is received
Return, elevator rises, so repeatedly.When being in an emergency, scram button is pressed, automatic/hand knob is beaten in manual gear,
Each knob is adjusted according to actual conditions, device is returned to normal condition.Big material bin has material, and left small feed bin is not full, and left-hand screw is defeated
Machine is sent to work;Big material bin has material, and right small feed bin is not full, the work of right-hand screw conveyer;Big material bin is expired, then the full indicator lamp of big material bin
It is bright, while buzzer rings, system temporarily ceases work.For the interference of each functional part of anti-locking apparatus, when cutting knife moves, material
Bag upset must must be in the state of stretching in retracted state and jaw;During empty bag export, it is necessary to first open side door, when empty bag goes out
After storehouse push pedal returns, then side door closed.
Such as Fig. 2, the atmospheric control of packed polymer automatic charging device mainly has air compressor, pneumatic three
Part, 7 manifold valves equipped with two-position five-way solenoid directional control valve, flow speed control valve and various cylinders composition, in order that each executive component is transported
Dynamic steady, each cylinder is equipped with flow speed control valve.
The course of work of atmospheric control is as follows:In each magnetic valve of the original state of work all in power failure state.YAO
It is electric when, feeding pallet is stretched out, and pocket is put in people's feeding pallet, YAO dead electricity, and feeding pallet is withdrawn, and pocket is made a gift to someone lifting
In machine.When pocket lifting is arrived specified altitude assignment by elevator, YA2 obtains electric, front door opening, and YA1 obtains electric, pocket warehouse entry cylinder stretching
By in pocket Tui Ren broken bags mechanism, YA1 dead electricity, pocket warehouse entry cylinder is resetted, and YA2 dead electricity front door is closed, and elevator declines.YA4
Must be electric, jaw is stretched out, and pocket is caught on.YA6 obtain it is electric, cutting knife stretch out, pocket is broken from centre, YA6 dead electricity, cutting knife withdraw.
YAS obtains electric, and pocket tumble cylinder is stretched out, and polymer starts to fall, when polymer to the greatest extent when, YA4 dead electricity, jaw is withdrawn, empty bag
Freely fallen to material mechanism.YA5 dead electricity, pocket tumble cylinder are withdrawn.YA3 obtains electric, side door opening, empty bag processing mechanism general
Outside empty bag ejecting device.YA3 dead electricity, side door are closed.And so on circulate.
Such as Fig. 3, the start and stop of packed 7 motors of polymer automatic charging device electric control system major control and each electricity
The commutation of magnetic reversal valve.Lift portion is realized by hoist engine, when relay KA6 coils obtain electric, KA6 2 normally opened contacts
Closure, elevator is begun to ramp up, when relay KA7 coils obtain electric, KA7 2 normally opened contacts closure, under elevator starts
Drop.Empty bag processing unit is realized by the rotating of 1 threephase asynchronous, when contactor KM2 coil obtains electric, KM3
The main electric shock closure of coil losing electricity, at this moment contactor KM2, motor, which rotates forward, drives push pedal by outside empty bag ejecting device；KM3's
When coil obtains electric, KM2 coil losing electricities, motor reversal drives push pedal to return to initial position.The start and stop of remaining each motor are also all leaned on
The state of the normally opened contact of relay carrys out the coil of control contactor, to reach the purpose of controlled motor start and stop.Solenoid directional control valve
The coil of solenoid directional control valve is directly controlled to control the commutation of magnetic valve to act each several part cylinder by PLC output point.
PLC is the core of packed polymer automatic charging device control system.Required according to the specific control of device.PLC
29 input signals, 22 output signals are needed altogether.Therefore select the DC/DC/DC PLC 24 of S7-200 CPU 226 to enter 16 and go out, directly
24 V power supplies are flowed, and are provided out 24V outputs, extension enters the 8 digital quantity I/O expansion modules EM223 gone out for one 8.
Such as Fig. 4, in the work of reality, conventional software implementation method mainly has experience design method, Logic based method.Root
Order functional approach is used according to the control requirement of packed polymer automatic charging device control system, and passes through V4.0STEP 7
MicroWIN SP6 programming softwares carry out the PLC programmings of manually and automatically two states.
Point-to-point control is realized in control mainly by the button in guidance panel and touch-screen manually, and an input corresponds to
One output；When automatically controlling, start button is pressed, system completes all functions according to automatic control program in sequence.
In manual mode, the auxiliary reclay in all automatic subroutines is resetted, during auto state, to reset in manual subprogram
Auxiliary reclay.
