Device and method for automatically detecting redried tobacco strip identification and box core temperature based on visual identification

Abstract

The invention discloses a device and a method for automatically detecting redried tobacco strip identification and box core temperature based on visual identification. A visual identification tobacco strip identification unit is located above a tobacco box conveying roller way, a discharging baffle is automatically opened after a tobacco box enters a main body device, the feeding baffle is lifted after the position of a box body is positioned, a lifter descends to the height of an identification position, when the light source is turned on, an industrial camera takes a picture and then rises to an initial position, visual identification software system acquires, identifies and analyzes information of the picture to automatically identify a smoke box needing temperature measurement, after the infrared locator finds the position accurately, the rotator descends to the surface of the smoke box and rotates according to the size of a central opening gap of the smoke box, the drilling device moves to the center of the surface of the box body for descending drilling, the drilling shaft moves forwards and backwards after ascending, a temperature measuring rod descends to a deep hole after being automatically positioned and automatically returns after temperature measurement is finished, the feeding baffle and the discharging baffle descend at the same time, and the smoke box is discharged out of the main body device. According to the device and the method, the actual requirements of modern equipment on identification and temperature detection of the flue-cured tobacco lamina on a production line are met.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a device and method for automatically detecting the mark of re-cured sheet tobacco based on visual recognition and box core temperature. Background technique [0002] In the leaf threshing and redrying production process, the temperature of the off-line finished tobacco box is an important quality technical index. The quality technical requirement for this index in the redrying industry is 35°C~45°C (YC / T 147-2010). At present, the temperature detection of the finished cigarette box is based on customer requirements, and the detection method is mainly in different specifications of the box (length * width * height = 1136mm * 720mm * 725mm, length * width * height = 1136mm * 690mm * 725mm) Drill a hole with a depth of about 500mm in the center of the front, and then quickly insert a plunger thermometer to measure the temperature. After the temperature value is stable, read the tem...

At present, the temperature detection of the finished cigarette box is based on customer requirements, and the detection method is mainly in different specifications of the box (length * width * height = 1136mm * 720mm * 725mm, length * width * height = 1136mm * 690mm * 725mm) Drill a hole with a depth of about 500mm in the center of the front, and then quickly insert a plunger thermometer to measure the temperature. After the temperature value is stable, read the temperature value, record it manually on site, and enter it into the system. The complete steps of manual temperature measurement are completed. The process takes a long time; the verification method of cigarette labels is mainly to check the content of the labels on both sides of the cigarette box online at a certain frequency.

[0003] At present, in the process of detecting the temperature of the smoke box, there are shortcomings such as high drilling labor intensity, long temperature measurement time, and low detection efficiency; the number of off-line smoke boxes is large, the frequency of the identification verification process is low, and the verification information content is large. The content is wrong and not found in time, which directly leads to the unqualified appearance of the product
