Description

Technical Field

[0001] The present invention relates to the field of cigarette detection, and more specifically, to a cigarette detection device and a cigarette detection method. Background Art

[0002] During the tobacco manufacturing process, cigarettes are sorted and packaged into cartons. A 32-bit digital code is printed on the outer wall of the cartons, and the digital code needs to be entered before the product leaves the factory. However, the existing code position is uncertain, resulting in most of the entry method being to manually find the coding area first, and then place the coding area on the corresponding recognition area of ​​the scanning machine, and then remove it after entry. The entire process requires manual operation, and there is still room for improvement in production efficiency.

[0003] In the existing technology, Chinese utility model patent CN203392306U discloses a "cigarette carton confirmation control device in a cigarette sorting system", which was published on January 15, 2014. An electric control box for controlling the operation of the cigarette sorting system and a cigarette bin group for storing cigarette carton are provided on one side of the sorting frame. The cigarette bin group is provided with a mixed bin for storing two or more cigarette carton specifications and a single bin for storing a single cigarette carton specification. A cigarette carton conveyor belt is installed on the sorting frame, and a cigarette outlet of the mixed bin is provided with a cigarette outlet confirmation plate connected to the cigarette carton conveyor belt. A barcode scanner for detecting cigarettes on the cigarette outlet confirmation plate is provided on the sorting frame. In this solution, a barcode scanner is set on the sorting rack, and the barcode scanner is matched with the cigarette output confirmation plate of the mixed bin or the cigarette output guide plate of the single bin for corresponding scanning, so that confirmation and control can be performed when there is an error in the cigarette output from the cigarette bin. However, the barcode scanner is only set in one direction. If the barcode on the cigarette carton is not facing the barcode scanner or the cigarette carton is placed at an angle, the barcode scanner cannot effectively scan the cigarette carton and cannot obtain the cigarette carton information.

S4: When the cigarette cartons are transferred to the position of the cigarette pushing mechanism, the cigarette pushing mechanism pushes the cigarette cartons onto the supporting plate. The third camera photographs both sides of the cigarette cartons, and the image processor makes a judgment. If normal digital codes are detected, they are recorded, and subsequent photographing and detection are not required, and the cigarette pushing mechanism is started to send the cigarette cartons back onto the conveyor belt again. If incorrect digital codes are detected, subsequent detection is not required, and they are directly pushed off the supporting plate. If no digital code is detected, subsequent detection continues. S5: When no result is obtained from the previous detections, the fourth camera photographs the bottom surface of the cigarette cartons in two steps. First, the fourth camera takes a photograph once, and the image processor makes a judgment. If normal digital codes are detected, they are recorded, and subsequent photographing and detection are not required, and the cigarette pushing mechanism is started to send the cigarette cartons back onto the conveyor belt again. If no digital code is detected or the digital code is partially incomplete, a second photograph is taken. The fourth camera photographs the bottom surface of the cigarette cartons again, and the image processor makes a judgment. If normal digital codes are detected, they are recorded and the cigarette pushing mechanism is started to send the cigarette cartons back onto the conveyor belt again. If no digital code is detected or the digital code is partially incomplete, they are directly pushed off the supporting plate.
