用于蛋白肠衣定长剪切的光电检测系统

Photoelectric detection system for cutting collagen casing with the fixed length

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。

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 TM4C123GH6 PM 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 ±0.05 m.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.
