本发明涉及白砂糖全自动包装生产装置的技术领域，具体是一种白砂糖全自动包装生产线的重袋检测系统。The invention relates to the technical field of a fully automatic packaging production device for white sugar, in particular to a heavy bag detection system for a fully automatic white sugar packaging production line.
背景技术Background technique
白砂糖根据品质的不同分为精制糖、优级糖、一级糖和二级糖。国内常见的日产1200吨中小型精糖厂日产值约为800万元、年产值约为25亿元；日产4000吨的大型精糖厂日产值约为2700万元、年产值约为80亿元。糖厂的白砂糖是在甲膏分蜜后得到，得到白砂糖后，还需经过干燥-磁选-筛选-检验-定量包装-入库，才向市场销售。然而在定量包装过程中，传统的包装是采用人工包装，效率极低。为了提高生产效率，很多制糖厂都采用了白砂糖全自动包装生产线，白砂糖全自动包装生产线，主要由PLC控制系统，以及受控的袋仓、取袋送袋机、上袋机、高速定量称、白砂糖填充机、折边缝包机、糖包输送机等精密执行单元组成，实现无人干预完成白砂糖装包生产。采用的白砂糖袋在进行糖袋移库仓储及发运到用户过程中，造成折叠、重压粘连问题糖袋，如果在取袋机吸取糖袋前，糖袋分离不好，当这样的糖袋进入自动包装线，取袋机就可能一次吸取多只糖袋，造成重袋被送至自动上袋机，开袋口机构误将重袋当是一个糖袋执行开袋口操作，致使错误打开重袋，糖袋口未能真正套入卸糖口，而套入卸糖口却是两个糖袋之间，造成白砂糖装包填充时糖撒出袋外，影响机械电气设备安全和生产能力，以及糖的损失。White granulated sugar is divided into refined sugar, high-grade sugar, primary sugar and secondary sugar according to the quality. The daily output value of a small and medium-sized sugar refinery with a daily output of 1,200 tons is about 8 million yuan, and the annual output value is about 2.5 billion yuan; the daily output value of a large sugar refinery with a daily output of 4,000 tons is about 27 million yuan, and the annual output value is about 8 billion yuan. The white granulated sugar from the sugar factory is obtained after the nectar is separated from the first paste. After the white granulated sugar is obtained, it needs to go through drying-magnetic separation-screening-inspection-quantitative packaging-warehousing before it can be sold to the market. However, in the quantitative packaging process, the traditional packaging is manual packaging, which is extremely inefficient. In order to improve production efficiency, many sugar factories have adopted automatic white sugar packaging production line, which is mainly controlled by PLC system, as well as controlled bag warehouse, bag taking machine, bag feeding machine, high-speed Quantitative weighing, white sugar filling machine, folding sewing machine, sugar bag conveyor and other precision execution units, to achieve unmanned intervention to complete the production of white sugar packaging. The white granulated sugar bags used in the process of moving the sugar bags to storage and shipping to the user will cause folding, heavy pressure and adhesion problems. Entering the automatic packaging line, the bag taking machine may absorb multiple sugar bags at a time, causing the heavy bag to be sent to the automatic bag loading machine, and the bag opening mechanism mistakenly regards the heavy bag as a sugar bag to open the bag, resulting in wrong opening Heavy bags, the sugar bag mouth is not actually inserted into the sugar discharge port, but the sugar discharge port is placed between two sugar bags, causing the sugar to spill out of the bag when the white sugar bag is filled, affecting the safety and production of mechanical and electrical equipment capacity, and loss of sugar.
发明内容Contents of the invention
本发明的目的是提供一种白砂糖全自动包装生产线的重袋检测系统，避免白砂糖全自动包装生产线在上袋过程中出现重袋，造成白砂糖装包填充时糖撒出袋外，影响机械电气设备安全和生产能力，以及白砂糖的掉落损失。The purpose of the present invention is to provide a heavy bag detection system for the automatic white sugar packaging production line, so as to avoid the occurrence of heavy bags during the bagging process of the white sugar automatic packaging production line, causing the sugar to spill out of the bag when the white sugar is packed and filled, affecting Safety and production capacity of mechanical and electrical equipment, and loss of white granulated sugar.
过去采用的白砂糖袋在进行糖袋移库仓储及发运到用户过程中，容易造成折叠、重压粘连问题糖袋，如果在上袋过程，糖袋分离不好，当这样的糖袋进入自动包装线，取袋机就可能一次吸取多只糖袋，造成重袋被送至自动上袋机，开袋口机构误将重袋当是一个糖袋执行开袋口操作，致使错误打开重袋，糖袋口未能真正套入卸糖口，而套入卸糖口却是两个糖袋之间，造成白砂糖撒出糖袋外。经发明人观察分析，集思广益，认为在取袋前后工序加强管理，把糖袋问题反应给生产厂家的同时，有必要结合自动包装线进行改造，增设重袋检测识别及剔除装置。The white granulated sugar bags used in the past are easy to cause folding, heavy pressure and adhesion problems during the sugar bag transfer storage and delivery to the user. If the sugar bags are not well separated during the bagging process, when such sugar bags enter the automatic In the packaging line, the bag taking machine may absorb multiple sugar bags at a time, causing the heavy bag to be sent to the automatic bag loading machine. The bag opening mechanism mistakenly regards the heavy bag as a sugar bag and executes the bag opening operation, resulting in opening the heavy bag by mistake. , The mouth of the sugar bag is not really inserted into the sugar discharge port, but it is placed between the two sugar bags, causing the white sugar to spill out of the sugar bag. After observation and analysis by the inventor, and brainstorming, it is believed that it is necessary to strengthen the management of the process before and after bag taking, and to reflect the problem of sugar bags to the manufacturer. At the same time, it is necessary to combine the automatic packaging line for transformation and add heavy bag detection, identification and removal devices.
白砂糖全自动包装生产线生产能力为每小时800包，每道工序都连续完成，而且机械结构精密紧凑。白砂糖袋是由聚丙稀丝带编织而成，具有半透光物理特征，厚度一致性好。综合多种解决方案，拟定选取光电传感器作重袋检测识别。The production capacity of the white sugar automatic packaging production line is 800 packs per hour, each process is completed continuously, and the mechanical structure is precise and compact. The white sugar bag is woven from polypropylene ribbon, which has semi-transparent physical characteristics and good thickness consistency. Combining various solutions, it is planned to select photoelectric sensors for heavy bag detection and identification.
光电传感器作重袋检测原理为：光波照射经半透光物后亮度下降的物理现象，而且下降多少与厚度有关，同理，单只糖袋和重袋透光量必定不同，只要检测光波照射经白砂糖袋亮度下降量多少，即可判断是否重袋。我们随机抽取多组糖袋样品，用亮度测量仪，进行糖袋透光测量实验，测量单只糖袋和两只的重袋的透光亮度，测得两组数值均符合单只糖袋较大，重袋较小的规律，而且单袋与重袋透光亮度数值分辨力好，重现性好，从实验证实光电传感器作重袋检测识别是可行的。The principle of photoelectric sensor for heavy bag detection is: the physical phenomenon that the brightness decreases after light waves irradiate through semi-transparent objects, and how much the decrease is related to the thickness. Similarly, the light transmission of a single sugar bag and heavy bag must be different, as long as the light wave is irradiated Whether the bag is heavy can be judged by how much the brightness of the white sugar bag drops. We randomly selected multiple groups of sugar bag samples, and used a brightness measuring instrument to conduct a sugar bag light transmittance measurement experiment to measure the light transmittance brightness of a single sugar bag and two heavy bags. Large and heavy bags are smaller, and the single bag and heavy bag have good resolution and reproducibility of light transmission brightness values. Experiments have proved that photoelectric sensors are feasible for heavy bag detection and identification.
