Between 6mm. Have before grey drawknife detect the capacitance type sensor that cloth seams. When close drawknife of seam of join having cloth, requirement drawknife and grey open a paragraph of space quickly, make an appointment with 40-60mm. Primary system uses air cylinder to open, shut. Because air cylinder is inherent characteristic, make control effect not ideal. We eat rubber roll of electric machinery drive through the pace, undertake clearance is adjusted achieve ideal result. 2, the system forms grey to need two sides processing, fluctuation two sides is blown at the same time except protuberant fiber. Two drawknife and two glue axis cooperate to make two jobs rod, it is axis of A, B respectively. Two end have every axis respectively one the gait o fan actor or actress in Beijing opera enters electric machinery, a machine and B machine. Below systematic graph: Technological process sketch map every the gait o fan actor or actress in Beijing opera has a drive into electric machinery, in all 4 driver, driver is controlled by PLC. Electric machinery take-off outputs rubber roll via decelerate machine. Because great majority PLC has two high speed to output a mouth only, controallable two the gait o fan actor or actress in Beijing opera take electric machinery drive. Also can use a lead plane to add high speed to locate module finishs the control to 4 electric machinery, but cost of fixed position module is higher. This system used two stages to amount to DVP14ES PLC. The stage amounts to DVP series PLC to input output the smallest for 8 into / 6. Because the price is reasonable, this system uses 2 lead plane, still add fixed position module than other brand type appropriate, and input, configuration giving an amount is more reasonable also. The Y0 of high speed pulse of a PLC, Y1 controls 2 the gait o fan actor or actress in Beijing opera to take the traversal speed of driver, its Y4, Y5 controls a pace to take the locomotive way of driver respectively, the pace asks to input speed signal and directional signal into electric machinery driver. 3, working principle 3.

1 drawknife and rubber roll parallel are adjusted. As a result of some reason, the likelihood brings about drawknife and rubber roll rough travel, namely both sides of an axis left and right sides and drawknife space size are abhorrent. Can adjust an electric machinery in working axis, make its rise or drop make drawknife and rubber roll parallel. After adjusting parallel, can make this rubber roll investment is used normally. On man-machine interface the design has the hand of machine of A of control A axis and machine of B axis A to use button. Clearance is measured by feet of a place of strategic importance. 3.

2 workshop are adjusted unoccupied placely. Before investment is used automatically, must undertake adjustment to clearance. There are two kinds of methods to be able to come true on the interface. One kind is the dot uses control, another kind is set moving data undertakes controlling. The dot moves control to apply to when knowing rubber roll and drawknife clearance the first time adjust clearance. Move control to make rubber roll and drawknife clearance are with the dot above all 0, namely zero. Next again the set on man-machine interface opens clearance to measure. When changing grey breed, require a basis only difference of ply of two kinds of grey, the clearance that set should change is measured can. Nextpage 3.

The design of 3 man-machine interface. Interface of a man-machine is linked together through RS485 communication line and 2 PLC. In man-machine interface programming, can use the macroinstruction that PWS offers, a pushbutton control the auxiliary relay M20 of two PLC, namely automatic pushbutton. When M20 is ON, the working status of two PLC is automatic mode. It is OK to be returned on man-machine interface the drawknife when set moves automatically opens space. Respectively two numerical value input pushbutton, write into two PLC, classics count occupies commutation, enter the pulse sendout of electric machinery controller as the pace. After zero job is finished, adjust working space, make M20 buy is ON next, investment moves automatically. 3.

4 paces enter the setting of electric machinery driver. The pace is into the fractionize setting of electric machinery driver 0.

72, namely PLC output takes electric machinery drive to the pace every 500 pulse, the pace rotates into electric machinery take-off a week. The high speed of fractionize value and PLC outputs a command to close suitably. Because load is big,the electric machinery when fractionize is too big is met and lose a condition, fractionize too hour, when moving automatically, open a space insufficient and make cloth is seamed be blown. Control system pursues 4, applied effect and problem pass for some time move, it is normal to prove the system moves, achieved design requirement. In programming, when using high speed to output command PLSY, electric machinery loses a condition when quicken, cause control flabby, instead uses PLSR order later. When using PLSR to command, must have installed increase slowdown time. After instead PLSR commands, go on a long journey stable and reliable. Because use two PLC, operating mode of its control object is same, just the same of two PLC program, the program is debugged handy. CNC Milling
