And the second scanner 13 is used for completing scanning of codes on all the monomers in the whole box once after the monomers are boxed, numbering all the data sequentially from small to large according to the sequence of rows and columns of the monomers in the whole box, completing secondary numbering, and uploading the data obtained by the secondary scanning to the upper computer 11.
The upper computer 11 is configured to perform the deficiency according to the data obtained by the primary scanning when the data obtained by the secondary scanning is missing, specifically perform the deficiency according to the consistency of the primary number, the secondary number and the boxing sequence, and take the data after the deficiency as the code acquisition result of the box monomer.
In a specific implementation, for example: the first scanner 12 scans the single bottle code and numbers M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16, M17, M18, M19, M20, and stores the data in the upper computer data queue memory.
And (3) according to the conventional boxing sequence of the existing assembly line, when the single bodies are boxed, the single bodies are boxed according to the scanning sequence of the single bodies.
When the second scanner 13 scans the whole beer, and when the bottle cap data is not read, the data which is not scanned is calculated by using the sequence in the read data queue of the first scanner 12. For example, the data Read by the second scanner 13 are M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16, M17, no Read, M19, M20. Then, no Read data, M18 can be calculated and verified based on this data being the next data of M17 and the last data of M19, resulting in completed data M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16, M17, M18, M19, M20.

In a specific implementation, for example: the first scanner scans the single bottle codes and is numbered as M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16, M17, M18, M19 and M20, and stores the data into the upper computer data queue memory.
And (3) according to the conventional boxing sequence of the existing assembly line, when the single bodies are boxed, the single bodies are boxed according to the scanning sequence of the single bodies.
When the second scanner scans the whole beer box and the bottle cap data cannot be read, the data which cannot be scanned is calculated by utilizing the sequence in the data reading queue of the first scanner. For example, the data Read by the second scanner are M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16, M17, no Read, M19, M20.
