Description

Description
Quality Inspection System and Method for Cigarette Products or Filter Tips Technical Field
The present invention relates to an inspection system and method, and in particular to a quality inspection system and method for cigarette products or fdter tips.
Background
Today, modem cigarette manufacturing machines can yield fdter-tipped cigarettes at a high rate of over 20,000 cigarettes per minute, and filter tip forming machines are capable of producing filter tip at a rate of 1,000 meters per minute. In an effort to realize massive production, multiple product manufacturing machines are typically used for concurrent production in cigarette workshops. To achieve the purpose that manufacturing machines can produce, under high-speed production conditions, products meeting quality standards such as cigarettes or filter tips, and to gain the capability of inspecting whether their draw resistance, ventilation degree, weight and external physical characteristics (e.g. length, circumference, roundness, etc.) are consistent with technical indices, the common practice is to take a sample out of the manufacturing machine using a manual or automatic sampling system and then transport the sample to measurement systems for measurement to determine whether the quality indices of the sample conform to technological requirements.
To date, inspection methods featured by manual sampling have yet to be thoroughly improved or replaced on account of the presence of technical defects in automatic measurement systems. The conventional automatic sampling technologies that are being studied generally can be divided into two categories: one is one-to-one system configuration in which the technical quality of products is inspected and controlled on the premise that one sampling and measurement system corresponds to one of the manufacturing machines; and the other appears in the form of one-to-many system configuration, which is to say, one measurement system corresponds to a plurality of remote samplers, and samples are transported through pipelines to measurement systems for purposes of inspection and technical control. Yet, there are still shortcomings in these two approaches: 1. As for the one-to-one system structure, it is imperative that one manufacturing machine is equipped with a set of independent measurement and sampling systems, and therefore there are high system costs for those workshops where as many as several tens of manufacturing machines are applied, and multiple measurement systems also lead to large workloads in system calibration, management and maintenance. More importantly, multiple sets of measurement systems will bring influence factors such as indefinite measurement results. As a consequence, to form an ultimate inspection basis for the quality of products, manual random inspection is still required. 2. In case of the one-to-many system structure, one measurement system corresponds to multiple remote samplers, and samples are transported to shared measurement systems through pneumatic pipelines to finish measurement. Its drawback lies in the fact that there are complex system structures and high operating, maintenance and construction costs since stationary samplers and transportation pipelines need to be mounted inside production workshops. What’s more, the current pneumatic pipelines transportation technologies are only applicable for transportation of filter tips. Damages to the sample or changes in technical indices occur when cigarette products are subjected to pneumatic transportation. Furthermore, different environmental temperatures at which the existing one-to-many measurement systems and manufacturing machines are kept will result in measurement errors of parameters affected by changes in environmental temperature, such as draw resistance and ventilation degree of the sample, as a result of which a true reflection of the inspection results cannot be offered.
In view of the above-mentioned problems existing in the prior art, the present invention provides an innovative quality inspection system for cigarette products or filter tips and a realization method thereof.
