The application of rotary encoder in cord cutting machine

xwc-1500 horizontal cutting machine is one of the necessary equipment in the tire industry, and its anti fading ability is better than that of non-metallic materials. This machine cuts the rubber hung fiber cord or canvas into a certain width and angle for the molding process. This machine can cut the cloth for bias and radial tires. The materials of the cut curtain canvas can be nylon, polyester, China Zhongwang also made an important breakthrough in rayon or cotton fiber

the machine is composed of a guide and storage device, a deviation correction device, a cutting device, a conveying device, an angle measurement and adjustment device, an air pipeline and an electrical part. Among them, conveying and angle measurement and adjustment are the key devices of the equipment, which directly determine the width and angle of the curtain canvas. Our company adopts the incremental rotary encoder (trd-n2500-rz) of Guangyang company to control the width of curtain canvas, and the absolute rotary encoder (trd-na1024nw5m) to control the angle of curtain canvas, which fully meets the accuracy required by users

conveyor: the cord conveyor of the horizontal cutting machine is driven by AC servo motor, which is used in conjunction with the incremental encoder and PLC of Japan Guangyang company, so that the cord conveyor can carry out high-precision stepless speed regulation within a certain range, and has stable positioning accuracy. The cutting length is set by touching the reality unit. When the cord fabric is running, the length measuring wheel drives the rotary encoder to rotate, and the photoelectric signal sent is counted by the built-in counter of PLC. After PLC calculation and comparison, the instantaneous threshold and stop of the motor speed of the conveyor are controlled to achieve the purpose of accurate positioning. The curtain canvas may have backlash in the actual operation of the conveyor belt device, so we use two-phase rotary encoder to ensure the accuracy of measurement

angle device:

the whole ruling device is installed here, which can rotate around a vertical spindle to adjust the cutting angle. The spindle is driven by an AC motor, and the center is equipped with an absolute photoelectric encoder produced by Japan Guangyang company. When the motor Jinan experimental machine factory 2017 welcomes you to drive the spindle to rotate, the photoelectric signal is sent to PLC for conversion processing, that is, gray code is converted into binary code and BCD code to obtain the corresponding angle, This angle is compared with the angle set by the PLC and the touch screen display unit. First, judge the forward or reverse rotation of the motor, stop after rotating to the set angle, and complete the automatic adjustment of the angle by positioning the cylinder lock

to facilitate the installation of the encoder, set the angle adjustment value on the touch screen. The significance of this value is as follows: when installing the equipment, first adjust the angle frame to the absolute zero point of the machine, and then install the absolute rotary encoder for angle measurement, so that the angle measurement value displays a small positive value, fix the encoder, and complete the installation of the encoder. At this time, look at the value displayed in the angle setting measurement value window, Take the negative value and write it into the angle setting zero adjustment value. At this time, the data in the actual value of the angle setting will be displayed as zero. In this way, the electrical angle zero and the mechanical angle. As mentioned earlier, the stability of this type of model is completely coincident with the relevant zero of the sample. When the angle frame is rotated inside, the rotation angle value will be completely consistent with the angle you set

conclusion:

through practical application, we know that the two encoders have accurate measurement and high precision, which fully meet the needs of users, and have also been recognized by users. (end)
