Description

System and method for cigarette product or filter rod quality detection

Technical field

The present invention relates to a detection system and method, and more particularly to a quality inspection system and method for a cigarette article or filter rod.

Background technique

Current modern cigarette manufacturing machines produce processed filter cigarettes at speeds in excess of 20,000 pcs per minute, and filter rod forming machines can produce filter rods at speeds in excess of 1000 meters per minute. In the cigarette production workshop, multiple product manufacturing machines are usually used in parallel to obtain large-scale production. In order to meet the requirements of high-quality production conditions, the manufacturing machine can process products that meet the quality standards, such as cigarettes or filter rods, and can detect the resistance, ventilation, weight and physical shape characteristics (such as length, circumference, roundness, etc.). To meet the process specifications, it is common to use a manual or automated sampling system to take the sample out of the manufacturing machine and send it to the measurement system for measurement to determine if the quality specifications of the sample meet the process requirements.

At present, the manual sampling detection method has not been fundamentally improved and replaced. The reason is that the technical defects of the automatic measurement system and the research of the conventional automatic sampling technology can be summarized into two categories: one type is one-to-one system configuration. That is, one sampling measurement system performs the product process quality detection and control corresponding to one of the manufacturing machines; the other is a one-to-many system configuration, that is, one measurement system corresponds to multiple remote samplers, and samples are taken through the pipeline. Launched into the measurement system for inspection and process control, but these two methods have the following deficiencies:

1. One-to-one system structure, one manufacturing machine needs to be equipped with an independent measurement and sampling system. For workshops with dozens of manufacturing machines, the system cost is high, multiple The measurement system brings a large amount of system calibration, management and maintenance work, and more importantly, the measurement results are uncertain due to multiple sets of measurement systems. Therefore, it is still necessary to retain the final evaluation basis for product quality after manual sampling inspection.

2, one-to-many system structure, one measuring system corresponds to a plurality of remote samplers, the sample is transmitted to a shared measuring system through a pneumatic pipe to complete the measurement, the disadvantage is that a fixed sampler and a conveying pipe need to be installed in the production workshop. The system structure is complex, the operation and maintenance and construction cost are high, and the current pneumatic pipeline transmission technical solution is only applicable to the transmission of the filter rod. For the cigarette product, the pneumatic emission will lead to sample damage or process index change, and the current one-to-many measurement system and The ambient temperature at which the machine is placed may cause parameter measurement errors such as sample suction resistance and ventilation that are affected by changes in ambient temperature, and may not truly reflect the test results.
