Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

In order to improve the accurate traceability of the cigarette quality of the enterprise, the embodiment provides a method for improving the unique identification and traceability of cigarette packs. The method of "one code for one item" is used to carry out a two-dimensional code on the trademark pack at the supplier link. Pre-printing, integrates the defect detector of packs and cigarettes with QR code data collection in the production process, and associates it with the No. 1 engineering code on the existing cigarettes. Therefore, for the first time in the tobacco industry, the online activation of the QR code during the production process of cigarettes has been realized, and the three-level association of "pack-condition-piece" of cigarettes has been established, which can only be traced back to "machine-team-day" from the past. Up to now, it can be traced back to "machine-team-time", which has greatly improved the accuracy of cigarette enterprises when tracing back faulty cigarettes, and greatly reduced the range of cigarettes scrapped due to faulty cigarettes, reducing the production cost of enterprises. The level of refined management and efficiency of the enterprise have been improved.

The method for improving the accuracy of unique identification and traceability of cigarette pack rods specifically includes the following steps:

Step 1: Code in the printing process of the trademark box.

The widely used QR two-dimensional code is selected as the information carrier for the unique identification of cigarette packs, the black code style is used on a white background, the fault tolerance rate is 15%, and 1-2mm blanks are reserved around. According to the packaging situation of cigarettes, hard-pack cigarettes, thin cigarettes, and stick cigarettes use "one item, one code + internal verification code", and soft-pack cigarettes use "one item, one code" because there is no flip cover. QR code size of cigarette pack: ≥8mm*8mm, QR code size of hard pack/soft pack: ≥10mm*10mm, QR code size of bar cigarette: ≥12mm*12mm.

Step 2: Activate the package strip of the QR code in the production process of the roll package.

When the packs and bars of cigarettes are activated online, the pack defect detector (referred to as pack CCD) and bar defect detector (referred to as bar CCD) on the existing packaging machine are upgraded, and the detection of appearance defects and the identification of QR codes are integrated into one. In the production process, the automatic collection, identification and storage of the two-dimensional code on the cigarette pack and the strip is realized, and the linkage elimination is realized. The specific measures are to install the probe part for QR code data acquisition on the basis of the mechanical structure of the appearance inspection system including CCD and strip CCD. The probe can effectively collect QR code information without affecting the normal detection and use of the original equipment. First, the single chip microcomputer in the IO control box judges that the cigarette pack on the packaging machine is in place according to the signal of the laser synchronization mechanism, controls the LED light source to light up, and then sends a pulse signal to the smart camera or decoder, and the smart camera or decoder collects the current QR code parsed after the image. If the two-dimensional code information is successfully parsed, the complete two-dimensional code information will be sent to the industrial computer, and the industrial computer will process and record the corresponding information, and upload the two-dimensional code information to the cigarette two-dimensional code data center through Ethernet; If the code analysis is unsuccessful, the IO signal is sent to the single-chip control board, and the single-chip computer notifies the rejection valve to perform real-time tracking and rejection according to the failure signal.

Step 3: Collect the "condition-condition" associated data of the QR code in the package production process. The "condition-condition" association is to upgrade the existing packing equipment. At the bottom of the cigarette production, where the cigarettes enter the boxing machine, a separation device is installed to ensure that each cigarette enters the collection field of view at intervals and does not stick to each other, and networking technology is used. Add the two-dimensional code collection and scanning equipment for cigarettes, that is, the networked code reader 1 and the networked code reader 2, and through the transformation of the linkage elimination, the elimination device is used to realize the linkage elimination of the unreadable two-dimensional code bar cigarettes. By docking with the No. 1 project code collection equipment in the tobacco industry, the information of the No. 1 project code of the smoke box is obtained, and the relationship between "conditions and conditions" is established according to 50:1. In order to ensure the accuracy of the packing sequence, an end verification collector is added at the end of the strip conveyor and at the entrance of the packing machine. When the box is full, the boxer sends a full box signal, and the end verification collector collects the QR code of the last cigarette. , and determine the current queuing order. If it is an integer multiple of 50 of the number of cigarettes in the whole box, it means that the packing sequence is correct, and the data is correlated and uploaded; otherwise, it will alarm and stop or remind the workers to check the relationship between the cigarettes and the box, and correct the corresponding "conditions-conditions" "relation. At present, the vertical case packing machine, horizontal case packing machine and horizontal (slim cigarette) case packing machine of cigarette enterprises are all applicable to this method.

Step 4: Three-level association of cigarette "pack-condition-condition". Through the collected two-dimensional code data of the pack, the three-level association of "pack-condition-condition" of cigarettes is established. According to the online QR code activation data for packs and bars of cigarettes in the packaging process, the production physical queue or time series can be used for logical calculation to form a 10:1 "pack-bar" relationship, and the production time can also be obtained; The precise correlation data of the condition of 50:1 at the sealing machine can calculate the 500:50:1 third-level data correlation relationship in the "package-condition-condition".

Step 5: Track and trace cigarettes. According to the established "package-condition-condition" three-level correlation data, the forward and reverse traceability of the problem cigarettes is carried out.

Forward tracing: Get a pack of cigarettes, obtain the QR code information of the cigarettes and the No. 1 engineering code information on the cigarettes according to the associated data through the QR code information on the cigarettes, so that the information can be accurately The recovery of the cigarettes in question. Reverse tracing: get the No. 1 engineering code information, obtain the QR code data of the cigarettes and packs of cigarettes according to the associated data, and use this information to obtain the production time, machines, teams, etc. Analysis and precision of the scrapping of problematic cigarettes.

Compared with the original "five-digit steel stamp", the method for improving the unique identification and traceability accuracy of cigarette packs can be traced back to the cigarette machine, team and production date, which is significantly narrowed to the machine, team and production time, which further satisfies the current situation. The requirements of accurate quality traceability and refined management have good application and promotion value in cigarette manufacturers in the tobacco industry.

The above-mentioned specific embodiments describe in detail the technical solutions and beneficial effects of the present invention. It should be understood that the above-mentioned embodiments are only the most preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, additions and equivalent substitutions made within the scope shall be included within the protection scope of the present invention.
