用于蛋白肠衣定长剪切的光电检测系统

为了解决目前肠衣企业生产线上胶原蛋白肠衣运行速度不均匀、套缩前后长度变化大,以及因切刀剪切位置缺少识别标志而产生误差等问题,采用了一种新的胶原蛋白肠衣定长检测法——喷码检测,设计了一套高精度的胶原蛋白肠衣定长剪切的光电检测系统。系统以现有的内存（TM4C123GH6PM）为微控制单元,以光电旋转编码器、喷码机、数字型彩色光纤传感器为主要元件,结合企业现有的肠衣套缩装置,对肠衣定长剪切生产过程进行了理论分析和实验验证。结果表明,肠衣的测量精度高达0.1mm,切割误差由±0.3m减少到±0.05m,平均每根肠衣可减少4%的生产成本。此光电检测系统非常适用于工业应用,可极大地提高企业竞争力。

Photoelectric detection system for cutting collagen casing with the fixed length

In order to solve the problem of non-uniform running speed of collagen casing production line, length change before and after retraction, and error caused by the lack of identification marks in cutting position of the cutter, a new collagen casing length detection method, spraying mark detection, was used, and a set of high-precision photoelectric detection system was designed to cut the fixed-length collagen casing.Based on microcontroller unit TM4C123GH6PM and using electro-optic rotary encoder, inkjet printer and digital color-sensing fiber sensor as the main devices, and utilizing the casings stretching facility in factory, the system makes the theoretical and experimental verification during the process of the cutting fixed-length collagen casing.The results show that the measurement accuracy of casing reaches 0.1mm, and the error cutting reduces from ±0.3m to ±0.05m.The average cost of produce for each casing can be reduced by 4%.The photoelectric detection system is suitable for industrial applications and can greatly enhance the competitiveness of enterprises.
