Description

A system and method for automatic proofreading of two-dimensional codes in the packaging process

technical field

The invention relates to the technical field of appearance detection equipment for cigarette packaging equipment, in particular to a two-dimensional code automatic proofreading system and method during the packaging process.

Background technique

With the increasing maturity of two-dimensional code technology, two-dimensional codes can enable barcodes to express more information in a limited geometric space and meet the needs of detailed descriptions of individual items. Technology favorite. Print the unique two-dimensional code logo pattern on the cigarette packaging box, so that the two-dimensional code cigarette packaging box has mobile terminal functions such as anti-counterfeiting, publicity, points, and redemption, and it will correspond to the background database one by one after the consumer scans the code. Activation can directly obtain consumers' first-hand information data and consumption feedback. After digital assistance and marketing drive, it can realize the organic interaction between the two parties and the accurate transmission of information, which will help to realize the promotion of brand value and consumer loyalty. However, due to the many links in cigarette production, the printing, transportation, warehousing and packaging production process of box skins are affected by many factors such as manpower and equipment, and the final cigarette database has low accuracy. Cigarette production continues to increase, and these invalid QR codes increase the burden on database operations and directly affect cigarette production management and marketing activities.

Contents of the invention

In order to ensure that the unique QR code on the cigarette package corresponds to the data in the background one by one and can be activated accurately. In the production line of cigarette packaging equipment, it is necessary to use the two-dimensional code detection and proofreading system to verify and input the two-dimensional code data of the packaging box, and to remove repeated codes, unrecognizable codes and two-dimensional codes with defective surface quality to ensure the integrity of the two-dimensional code correctness.

The invention discloses a system for automatic proofreading of two-dimensional codes in the packaging process. The physical distance from the electronic sensor eye to the shooting point of the camera, and from the camera to the box, the electronic sensor eye installed on the conveyor belt senses the cigarette and sends the information that the cigarette box has entered the detection area to the main detector, and the main detector passes The high-speed LAN is connected to the local data center server in the production workshop. The main detector is delayed to turn on the main camera to take two-dimensional code images. The main detector is used for data comparison and sends the detection results to the reject signal box, and the waste signal box is delayed. Start the fee-removing device to remove unqualified cigarette packs;

Further, a backup camera and a backup detection machine are also included.

The present invention also provides a method for automatic proofreading of two-dimensional codes during the packaging process, comprising the following steps,

S1, the cigarette box starts to enter the area to be detected with the transmission belt;

S2, the electronic sensor eye senses whether the cigarette case has entered the detection range, and sends information to the detection machine;

S3, the detector is ready to start the camera to shoot after receiving the information sent by the electronic sensor eye;

S4, the camera captures the two-dimensional code image on the cigarette package and scans the scanned two-dimensional code information at the same time and returns it to the detection machine;

S5, the detection machine receives the information, and calls the two-dimensional code database information in the local server;

S6, the detector compares the captured two-dimensional code information with the two-dimensional code database information provided by the server;

S7, judging whether the two-dimensional code information is consistent;

S8, consistent is the qualified product, enter the next process;

S9, when the two-dimensional code information is inconsistent, the detection machine notifies to kick the waste signal box;

S10, the waste kicking signal box controls the opening of the waste rejecting port according to the delay signal of the encoder, and kicks out unqualified cigarette packs;

When the smoke waste rate of the batch exceeds the set upper limit, the system will send out an alarm.

The beneficial effect of the present invention is that it can proofread and inspect the last pass of the two-dimensional code logo printing on the small box and carton of cigarette packaging to ensure the uniqueness and accuracy of the two-dimensional code on the small box and carton. Each batch of valid two-dimensional codes collected by the computer processor is transferred to the two-dimensional code data processing server for backup and packaging. Thereby ensuring that the QR code on each pack and cigarette entering the market is unique, true and effective.

Detailed ways:

As shown in Figures 1 and 2, it is a system for automatic proofreading of two-dimensional codes in the packaging process according to the present invention, including an encoder 1, an electronic sensor eye 2, a main camera 3, a main detector 4, a server 5, and a kicker Waste signal box 6, rejecting device 7, when the cigarette box starts to enter the detection area with the transmission belt, the electronic sensor eye 2 installed on the conveyor belt detects the cigarette, and informs the main detection machine that the cigarette box has entered the detection area 4. The main detector 4 delays turning on the main camera 3 according to the preset distance (the encoder 1 can accurately calculate the physical distance from the electronic sensor eye to the shooting point of the main camera 3, and the physical distance from the main camera 3 to the rejecting device 7) Take the image of the QR code on the cigarette case, and after the main detector 4 obtains the image information, it will decode and compare the data immediately, and send the detection result and the serial number information of the product to the reject signal box 6, when the product reaches the reject port If it is an unqualified product, then turn on the rejecting device 7 to reject the waste, otherwise the cigarette box will pass through the rejecting port smoothly. When the waste rate of the batch of cigarettes exceeds the set upper limit, the system will send an alarm.

In order to ensure the accuracy of data collection, two cameras are designed in the detection area, one is the main camera 3 and the other is the backup camera 8. Under normal circumstances, only the main camera 3 is normally detecting the cigarettes on the packaging line, but once the main camera 3. If there is a problem, the server 6 will automatically enable the backup camera 8 to work. In this way, it can be guaranteed that in the case of any failure of a detection terminal, no manual participation is required, and the system will automatically ensure that the factory’s cigarettes will not affect production. The boxes are in one-to-one correspondence with the data in the two-dimensional code database.

The beneficial effect of the present invention is that: the last checkpoint of the printing process can be checked and checked for the two-dimensional code mark on the small box and carton of cigarette packaging, so as to ensure the uniqueness and accuracy of the two-dimensional code on the small box and carton, and at the same time Each batch of valid two-dimensional codes collected by the detector processor is transferred to the two-dimensional code data processing server for backup and packaging. Thereby ensuring that the QR code on each pack and cigarette entering the market is unique, true and effective.
