The actual position can be the position where the product code is actually located in the product picture, the preset position can be a preset product code identification position, and the identification rate of the product code on the preset position is high.
Specifically, the actual position of the product code in the product picture can be compared with the preset position, the horizontal distance between the actual position and the preset position is determined, and the time length of exposure time delay can be adjusted according to the horizontal distance, so that the actual position of the product code in the new product picture is located at the preset position. For example, the central area of the photo is set to a preset position, and when the product code is shifted to the right, the product is beyond the sampling area on the production line, so the time interval from the sampling trigger signal to the sampling start time, that is, the exposure delay, is shortened; the left side indicates that the product does not go to a sampling area on a production line, and the time interval from the sampling trigger signal to the sampling start time is prolonged, namely the exposure time delay.
Illustratively, taking the association of a product code and a package code that are not wet by urine on a production line as an example, the product association method in the embodiment of the present invention includes the steps of: 1. the method comprises the steps of spraying one object to one code on the diaper, namely the product code, wherein the code spraying position needs to be determined firstly, and the production line speed of the diaper industry is about 400 pieces/minute, 800 pieces/minute and 1200 pieces/minute. The production line speed is extremely fast, and in order to realize the jet printing of a thing sign indicating number to guarantee that the effect of jet printing needs to satisfy OCR discernment's standard typeface, needs shower nozzle speed be greater than or equal to production line speed, consequently need purchase the UV ink jet numbering machine that high-speed spouts the sign indicating number or other ink jet numbering machines that can reach this jet printing speed. In the method, one-object one-code spray printing position is selected at the waist tape position of the diaper product, the diaper product is formed by multiple materials, the production line speed of each material is different, the running speed of the waist tape material is one tenth of the production line speed, a medium-configuration code spraying machine can be selected, and therefore cost is remarkably reduced. Wherein, the one-object-one-chip code is composed of 16 digits, and the generation rule is that two rows of 12 digits on the left side are year, month, day, hour, minute and second, and two rows of 4 digits on the right side are a production line identifier and a sequence number of 0-20. The font of the one-object-one-code should be a standard printing font so as to facilitate the recognition of the camera algorithm.
The waist tape is made of rectangular material, and is formed by combining a roll of waist tape raw material with a diaper product after each sheet is cut on a production line by a cutter. The speed of the code spraying machine is 100 meters within 1 minute, the movement speed of the waist tape is less than or equal to the maximum spray printing speed of the code spraying machine, when the spray printing position on the waist tape is not aligned, the position of the spray head can be adjusted, and when the spray printing position on the waist tape is close to the left, the spray head is rotated anticlockwise; the spray head is clockwise rotated when the spray printing position on the waist paste is close to the right.
2. After the one-object-one code is sprayed on each diaper, the digital record of the one-object-one code needs to be identified to the system, and then the digital record is associated with the two-dimensional packaging code after the digital record is packaged. Because the production line has a plurality of procedures, and the diaper product is always positioned in the production line equipment, the equipment cannot be used for shooting the identification code. Therefore, in the method, a high-speed shutter camera is placed between an entrance and an exit of a packaging machine where products enter from production line equipment, the complete products can be exposed, for example, a 400-piece/minute production line is used, the speed of the products is about 7 pieces/second, after the high-speed camera takes a picture, the data of the picture code on the picture is analyzed by using an OCR (optical character recognition) technology or a deep learning algorithm, and after the data is analyzed successfully, the data is sent to industrial control; if the parsing is unsuccessful, a placeholder data is generated, and the placeholder data can be messy codes.
3. The correlation system of the upper computer can identify the recorded data sequence of the algorithm according to the number of the pieces (one pack of n pieces) of the product specification and the number of n/2 or n as a basis (determined according to the packing of 1 pack or 2 packs of one pack of products), and can judge whether to keep data or discard partial data according to the signal of a counter, wherein the counter can be arranged in a production line or a packing machine. When the correlation system keeps n data according to the signal of the counter, the correlation system packs and temporarily stores the part of the data X1 and accumulates the number of n again. When the packaging two-dimensional code Y1 is identified, X1 and Y1 are correlated, and the correlation time is recorded. The correlation system automatically adjusts the basic quantity of the temporary storage data according to the number of the selected pieces with different product specifications, thereby realizing the correct correlation of the different product specifications.
Further, there may be a waste disposal process flow in the association system:
the first waste disposal condition: one of the paddles of the packaging machine is empty.
The related system needs to synchronously remove the data of the waste products, for example, 40 pieces/package and 2 groups in one package, when the number of the current passing pieces of the point counter point is 16 pieces and the 17 th blade position is empty, the system ignores the first 17 pieces of data, and lists the 18 th piece of data as the next first piece, and when 20 pieces of data are met, the data are temporarily stored.
Waste discharge treatment condition two: the packaging machine is abnormal.
After the worker eliminates the abnormity of the packaging machine, the worker needs to select 1 group or 2 groups of products taken from the packaging machine, presses the corresponding button, and the association system rejects the corresponding amount of data. Or, a camera is added in the packaging machine, a photo is taken when the production line is stopped, a photo is taken when the production line is started, and the data of 1 group number is rejected by the correlation system by comparing the changes of products in the packaging machine with two photos, for example, 1 group in the packaging machine is reduced.
And (3) waste discharge treatment condition three: and associating successful product rejections.
The package code is selected to be released in the correlation system, the two-dimension code on the package can be scanned by using a fixed wired code reader, and the correlation relationship between the two-dimension code and the chip code is released in the correlation system.
Further, on the basis of the embodiment of the invention, the association system of the upper computer can perform system resetting, and if the reset data is selected in the association system, the system rejects the recorded data which are not associated yet, and all products on the production line need to be taken on the turntable of the packaging machine and in the channel.
The upper computer in the embodiment of the invention can acquire the diaper photo shot by the high-speed camera, acquire the code spraying characters in the diaper photo through image analysis, generate individual character segment information, transmit the individual character segment information to the industrial personal computer software through a Programmable Logic Controller (PLC) communication protocol, if induction triggering exists, but code spraying is not carried out (the code spraying is not exposed in a shooting area due to too large vibration displacement of the diaper), also generate empty space occupying data (messy codes), and the industrial personal computer associated software can store the received data character segments into the database in sequence. And the PLC receives the push rod signal, performs sectional combination and packaging on the acquired data according to the set number of the pieces according to the push rod signal, and the packaged data segment enters a secondary cache to wait for reading and storing of the two-dimensional code of the packaging bag. And when the chip code and the package code are accurately acquired, the association system automatically associates and binds the chip code and the package code and stores the association and binding into a background database so that a user can perform code scanning identification at any time and realize the final function of data.
The diaper can be inserted into the rotating disc paddle after being shot by the camera, if the diaper is taken out by a worker in the rotating disc process or other reasons cause empty blades of the paddle, the section of the diaper which is not enough for setting the number of the blades can be automatically blown and removed in the subsequent equipment, the system can also automatically detect and calculate the number of the section of the abnormal diaper and the number of the empty blades, and the corresponding digital character sections in the system are synchronously removed. Thereby ensuring the accuracy of the associated positions of the package code and the chip code.
If abnormal conditions such as package blocking and the like occur during the interruption of the packaging machine, workers are required to enter the packaging machine to take out the diapers of the corresponding group, then the information removing button is pressed, the system can automatically remove two combined and packaged character information sections, and then the following data association is continuously realized.
The association system can also be provided with the functions of sampling inspection, verification, resetting, unbinding and the like. The correlation system has a function of reminding the selective examination at set time intervals, the software interface can jump out of a selective examination reminding window when the set time intervals are reached, and the three-color alarm lamp can flash the yellow alarm lamp to remind workers to go to a production line to take down the diaper package for the selective examination. The workman can utilize the yard rifle of sweeping of workstation to acquire outsourcing two-dimensional code, the assigned position of input inquiry interface, the correlation system can present package code of automatic display and the piece code that corresponds, the workman can open this bag, take out the diaper wherein and read the piece code and compare, according to date time and serial number on the piece code, can compare one by one, it is mainly whether unanimous with the array sequence that shows in the system to compare the position around in the diaper place wrapping bag, if exceed half on corresponding, can regard as to realize that data association is successful. If the difference is large and the package is wrong, the production line needs to be stopped immediately, the computer end point clicks a reset button, the system can empty all the data which are recorded but are not bound, and the software system is reset. Meanwhile, workers need to empty all diapers in the packaging machine, all mechanical rods such as the push arm and the like reset to the original point, then the production line is restarted, and sampling inspection is performed again. Thereby maintaining accurate association of the system.
