As shown in Fig. 4 program circuit.If single pallet weight is about 15kg, be 25 lattice according to the shape of pallet and large young pathbreaker stress and strain model of mating formation, then arrange every lattice weight by dividing, required weight of material is 16.4kg altogether.
Initialization:
1, arrange 1#-10# to weigh hopper analog quantity parameter and address.Total start button 1SB1 is set; Always stop button 1SB0; Total startup indicator lamp 1HL1 address.
2, work automatic/hand way selection knob SA1 address is set.Hand signal indicator lamp 1HL2 is set, machine ringing indicator lamp 1HL3 address.
Manual mode:
Working mode selection knob 1SA1 is placed in manual position, the rotating forward of uniform unloader, the reversion of uniform unloader is controlled respectively with corresponding start button, stop button, the startup that belt motor, 1#, 2#, 3# material roller motor, 1# ~ 10# screw motor, dolly of mating formation rotate forward, dolly of mating formation reverses and stopping, weigh hopper door electromagnetic valve cylinder YV1, YV2, and mat formation dolly valve electromagnetic valve cylinder YV3, YV4 close and open.
Which can detect the motor of each equipment by stand-alone debugging, and whether valve opening and closing normal operation, demarcates weighing instrument, guarantee that its displayed value is consistent with actual value.
Automated manner:
According to technological requirement, the parameter such as gravimetric value, screw motor running frequency of each wood shavings needed for grid of mating formation is set in man-machine interface.
Working mode selection knob SA1 is placed in automated location, press auto-start button SB2,1#, 2#, 3# material roller motor runs at interval of sequence starting in 2 seconds, afterwards, interval 2-3 starts belt motor operation second, carries the material of front one applying glue operation to enter feed bin; Interval 2 starts uniform unloader and rotates forward after second, when travel switch 2SQ1 is met in rotating forward, connect the time relay time delay of PLC programming after 2 seconds, uniform unloader reversion runs, the time relay time delay that connection PLC when meeting travel switch 2SQ2 that reverses programmes 2 seconds, uniform unloader rotates forward operation again, and so forth.
When meeting bin-level of mating formation higher than low material level 2SQ5, dolly of mating formation moves to A position 1SQ1 entrance point and connects, time delay 2 seconds, and electromagnetic valve cylinder YV1 works, close 1#-10# hopper door, start the operation of 1#-10# screw motor simultaneously and material in feed bin is pushed dolly A position of mating formation; When the real-time displayed value of weight of hopper of weighing equal 1#-10# weight is set time, screw motor stops blanking, and electromagnetic valve cylinder YV2 works, and opens hopper door of weighing; Relatively 1#-10# Hopper Weight is until when material discharges all, and dolly of mating formation moves to B position 1SQ2, and circulate charging of weighing, and weighs until complete 1SQ3, D position, C position 1SQ4, E position 1SQ5.
