An on-line visual detection device and detection method for missing rods in a carton packing machine

Abstract

The invention relates to an on-line visual pack absence detection device and a detection method for a cigarette pack cartoning machine. A visual unit collects images during the cigarette pack cartoning process, and is connected with a data management system via an Ethernet switch for data communication. A barcode scanner and a control module collect cigarette carton barcode information and transmit the cigarette carton barcode information to the data management system. An input and output control module receives rejecting signals of the visual unit, and outputs the rejecting signals to a warning and rejecting module. The method comprises the steps of initializing the detection device; judging whether a cigarette pack of a certain layer in the cartoning machine is in place; if in place, processing, analyzing and transmitting images of the cigarette pack of the layer to the data management system; judging whether the cigarette pack of the layer has any defect; if so, emitting warming and rejecting signals. The invention prevents the radioactive pollution caused by radioactive substances in the measurement process and the contact pollution caused by artificial weighing measurement, reduces the system complexity, and avoids huge industrial control computer chassis or huge system control cabinets.

Description

technical field [0001] The invention relates to a detection equipment in the tobacco industry, in particular to an on-line visual detection device and detection method for missing rods of a cigarette case packing machine. Background technique [0002] Carton packing is the last process in the cigarette production process. When packing cartons, the carton packing machine sometimes works chaotically, especially when the carton packing machine has a large production flow or insufficient incoming materials. There will be abnormalities in the work of cigarettes, resulting in the lack of cigarettes. Although this phenomenon is a small probability event, once such missing cigarette boxes enter the market, it will cause unnecessary economic legal disputes among cigarette manufacturers, dealers and consumers. Disputes, and even seriously affect the reputation of the company, so the importance of missing strip detection and elimination control of cigarette boxes is self-evident. At p...
