Commonly used in copper platoon processing machine installation a grating ruler, to replace the traditional positioning block and the photoelectric sensor, its main 'relative motion of the distance by cable to the programmable controller (PLC). According to the grating ruler linear movement of distance and molded parts the mathematical relationship between the bending Angle of PLC programming.

　　當(dāng)用戶輸入要求折彎的角度，PLC可計(jì)算出光柵的理論位移。當(dāng)折彎油缸動(dòng)作，帶動(dòng)光柵尺付尺動(dòng)作，光柵尺之讀數(shù)（即主付尺相對(duì)移動(dòng)之距離）與光柵的理論位移一致時(shí)，PLC會(huì)命令電磁閥反向動(dòng)作，折彎油缸返回，完成折彎成型動(dòng)作。

When the user input requirements of bending Angle, the PLC can calculate the displacement of the theory of grating. When bending cylinder action, lead pay scale grating ruler, the grating ruler reading (i.e., the main pay scale of relative movement distance) consistent with the theory of grating displacement, the PLC will command the electromagnetic valve reverse action, bending cylinder returns, complete bending forming.

　　由此可見，采用PLC加光柵尺構(gòu)成的閉環(huán)控制，銅排加工機(jī)只需更改內(nèi)部程序即可實(shí)現(xiàn)不同的折彎角度及折彎生產(chǎn)過程自動(dòng)化，控制系統(tǒng)具有較高的智能化、柔性化功能，而且相比采用數(shù)字控制的折彎機(jī)而言，又具有良好的性價(jià)比。

Thus, PLC and grating ruler constitute a closed loop control, copper platoon processing machine can be realized only need to change the internal program of bending Angle and bending of the production process automation, control system with high intelligence, flexible function, and compared with adopting digital control bending machine, and has good cost performance.
