Sheet material imaging device and sorter using the same

Abstract

The invention discloses an imaging device for flaky materials and a sorting machine. The imaging device for the flaky materials comprises a belt conveying unit, an imaging unit and a locating suction disc sucking the flaky materials. A single set of belt of the belt conveying unit penetrates through the position between the locating suction disc and the imaging unit. The locating suction disc and the imaging unit are fixedly mounted on the two sides of the single set of belt of the belt conveying unit respectively in an opposite mode. A space allowing the flaky materials to pass through is reserved between the imaging unit and the single set of belt of the belt conveying unit. Air flow through holes allowing air flow to pass through are formed in the locating suction disc in the moving direction of the single set of belt of the belt conveying unit, and suction holes communicated with the air flow through holes are formed in the side, close to the imaging unit, of the locating suction disc in the direction perpendicular to the air flow through holes. According to the imaging device for the flaky materials and the sorting machine, other suction devices are omitted, the occurrence of the situations of skew, shaking and unevenness of the flaky materials in the transmission process can be avoided, the flaky materials can be flattened, shaking can be reduced, and the requirements of image detection can be met.

Description

technical field [0001] The invention relates to a sheet material imaging device used in a sorting machine, and also relates to a sorting machine using the sheet material imaging device, belonging to the technical field of financial equipment. Background technique [0002] With the rapid development of the economy, the circulation of currency is increasing. In the past, banknotes were sorted by manual sorting, which was time-consuming, labor-intensive, and cumbersome. In recent years, with the development and progress of technology, banknote sorting machines have been used more and more widely as special sorting equipment for financial companies and professional banks. [0003] The sorting machine is a financial machine used for counting and sorting banknotes. It uses its internal image recognition technology and counterfeit currency identification technology to detect the authenticity of banknotes. Nowadays, there are many types of sorting machines on the market, which mai...

Problems solved by technology

However, this detection method often has the following defects: once one side of the banknote is stained, it will cause the sorter to fail to recognize it, which will affect the overall detection efficiency

At this time, the sheet material is supported by a single set of belts, and it is prone to jitter, especially when the depth of field of the camera is small, the slight up and down jitter has a great influence on the effect of high-quality programs; in addition, the sheet material (banknote) The unevenness of itself will also affect the imaging quality of the camera
