Vacuum reversion information checking system based on radio frequency identifications and error prevention method

Abstract

The invention discloses a vacuum reversion information checking system based on radio frequency identifications and an error prevention method. The radio frequency identifications are arranged on multiple vacuum reversion material boxes used for containing cut tobaccos, a first radio frequency identification reading and writing device used for writing cut tobacco information into the radio frequency identifications is arranged on the loading area of a circular conveying channel used for conveying the vacuum reversion material boxes, and a radio frequency identification code reader and a second radio frequency identification reading and writing device are arranged on the discharging area of the circular conveying channel; in addition, a controller in communication interaction with the first radio frequency identification reading and writing device, the radio frequency identification code reader and the second radio frequency identification reading and writing device is further included and is connected with a power device of the circular conveying channel in a control manner. The automation manner is adopted in the whole system for checking whether information of the cut tobaccos contained in the material boxes after vacuum reversion treatment is the same with the information of cut tobaccos in materials producing in the downstream procedure or not, the happening of tobacco mixing is reduced, and manual cost is saved.

Description

technical field [0001] The invention relates to the technical field of control of a vacuum dampening machine on a tobacco shred production line, in particular to a vacuum dampening information verification system and an error prevention method based on an electronic label. Background technique [0002] In recent years, the tobacco shredded production line and its control technology have made great progress. Both the production control accuracy and the information level have been greatly improved. However, the hidden dangers of quality accidents, especially the hidden dangers of major quality accidents, have not been eliminated; for example, mixed smoke (also known as "mixed brand") accidents, refers to different batches, different brands of tobacco leaves (or shredded tobacco) mixing accidents occurred where they should not be mixed; Sometimes it may even lead to the scrapping of the entire batch of materials, causing significant economic losses to the enterprise.

Problems solved by technology

[0002] In recent years, the tobacco shredded production line and its control technology have made great progress, both the production control accuracy and the level of informatization have been greatly improved, but the hidden dangers of quality accidents, especially major quality accidents, have not been eliminated; for example, mixed smoke (also known as "mixed brand") accidents, refers to different batches and different grades of tobacco leaves (or shredded tobacco) mixed accidents where they should not be mixed; Sometimes it may even lead to the scrapping of the entire batch of materials, causing significant economic losses to the enterprise

[0003] At present, in the production line of vacuum moisture treatment for shredded tobacco, the material box containing shredded tobacco is sent to the downstream process for product production after the vacuum moisture conditioning machine is used for vacuum moisture conditioning. Different times and grades, it is likely to cause mixed smoke during the production process of downstream products; Afterwards, the on-site operators will carefully patrol and other methods to reduce the occurrence of such failures, but this can only partially solve the accidents visible to the naked eye, and is also affected by factors such as the quality and fatigue of the on-site operators, and most of these accidents only discovered after the fact
