Description

Technical Field

[0001] The present invention belongs to the technical field of labeling, and particularly relates to an irregular package automatic labeling system. Background Art

[0002] At present, when domestic cross-border logistics packages are warehoused, it is necessary to manually weigh and read the codes of the packages, and then take the two parameters of weight and bar code to foreign carriers to apply for new waybills. There are also situations where the same package requires one waybill and one customs declaration form. At the same time, there are also some situations such as charged items and dangerous and prohibited items. For different package situations, there is a corresponding set of disposal processes, resulting in a slow manual input speed, generally 400 tickets / hour; a high error rate, averaging about fifteen per ten thousand, ultimately leading to wrong shipment of packages, causing user complaints and company compensation. With the company's daily processing volume of 1.2 million tickets, it compensates customers about 186,000 yuan / week, resulting in increased costs. Summary of the Invention
