Background
Blow-by is a business with the ultimate goal of profitability. The intentional sales of the dealer across the sales area covered by the dealer and in other areas is a blow-by behavior, also called as a flushing, which is a malignant marketing phenomenon that a company branch or an intermediate in a business network is driven by benefits to sell the distributed product across areas, causing market rolling and price confusion, and seriously affecting the reputation of a manufacturer. The current method for preventing the fleeing goods mainly comprises the step of adding carriers carrying product traceability information, such as one-dimensional codes, two-dimensional codes and the like, on product packages.
For domestic canned products, the common production mode of the tracing anti-channeling means is as follows: when the tank packaging material is in a flat state, the tracing anti-channeling codes such as the two-dimensional codes are printed on the surface of the material in a printing stage. The method can only be applied to canned products made of metal materials, and is not applicable to canned products made of plastic materials formed by injection molding. However, after the flat metal material is sprayed with the code, operations such as can body rolling, repair coating and the like still need to be performed, and the identification effect of the tracing anti-channeling code such as the two-dimensional code can be affected to a certain extent. The production method is as follows: and (3) manufacturing a label containing a two-dimensional code and other traceable anti-channeling codes in a printing factory, and then attaching the label to a can body of a canned product in a product production stage. Although the method can be suitable for canned products made of all materials, the label is easy to tear and replace, and the safety is not strong. Furthermore, neither method is applicable to canned products that have been made into finished products, such as imported products.

Example 1
Fig. 1 is a flow chart of a method for producing a traceable and anti-channeling code for a canned product according to an embodiment of the present invention, which is applicable to the production of the traceable and anti-channeling code for a finished canned product. As shown in fig. 1, a method for producing a traceable and anti-channeling code for canned products according to an embodiment of the present invention includes:
s110, acquiring two-dimensional code image information of the finished canned product.
Specifically, the finished canned product refers to a ready-made canned product that is available for use or sale. Two-dimensional codes are also called two-dimensional bar codes (2-dimensional bar Code), the most common form is QR Code (Quick Response Code), and the two-dimensional codes are distributed alternately in black and white on a plane (in two-dimensional directions) according to a certain rule through a certain specific geometric figure so as to record data symbol information. The two-dimensional code has the characteristics of large storage capacity, high confidentiality, high traceability and the like, and at present, a plurality of factories paste two-dimensional code labels on commodities, and the two-dimensional code is used for preventing, channeling and tracing.
Further, the barcode images for tracing and preventing the channeling of the commodity are collectively called a tracing and preventing channeling image, such as a two-dimensional code image, a micro graphic unit image and the like. The content contained in the traceable anti-channeling image is called traceable anti-channeling image information, and generally comprises a product query link and a code value, wherein the product query link is used for querying product information displayed by the traceable anti-channeling image, the code value is equivalent to an identity of the traceable anti-channeling image, and different traceable anti-channeling images have different code values. The two-dimensional code image information is content contained in the two-dimensional code image and comprises a first product query link of the two-dimensional code image and a first code value of the two-dimensional code image, and the two-dimensional code image information, namely the first product query link of the two-dimensional code image and the first code value, is obtained.
In this embodiment, the two-dimensional code image information may be obtained by scanning the two-dimensional code image with a dedicated two-dimensional code acquisition camera. The two-dimensional code image can be a two-dimensional code image on a two-dimensional code label which is already stuck on the finished canned product by a supplier of the finished canned product, or can be a two-dimensional code image generated after the merchant carries out secondary processing on the finished canned product which is not provided with the two-dimensional code image. For example, a domestic supplier of a finished canned product typically attaches a two-dimensional code label to the finished canned product, and a foreign imported finished canned product may not typically attach a two-dimensional code label, so that secondary processing is required for the imported finished canned product, and the two-dimensional code label is attached to the surface of the finished canned product, so that two-dimensional code image information can be obtained.
S120, generating a micro graphic unit image according to the two-dimensional code image information.
Specifically, the microscopic graphic unit image refers to a microscopic coding image with a code point diameter of about 30-60 microns, and the microscopic graphic unit image not only can record a large amount of data, but also is extremely difficult to copy, and a plurality of identifiable units exist in a certain area, and even if the microscopic graphic unit image is damaged in a large area, information can still be effectively read, so that a good anti-counterfeiting and anti-channeling effect can be achieved, and the microscopic graphic unit image has great advantages in tracing and anti-channeling application.
Further, the micro graphic unit image also has micro graphic unit image information including a second product query link of the micro graphic unit image and a second code value of the micro graphic unit image.
Generating a second code value according to a first code value of the two-dimensional code image, generating a second product query link according to a first product query link of the two-dimensional code image, and generating a micro-graphic unit image comprising the second code value and the second product query link by adopting a special micro-graphic unit image generation algorithm according to the second code value and the second product query link.
Further, according to the generation process of the micro graphic unit image, the first product query link is consistent with the second product query link, and the first code value is consistent with the second code value. The first code value being consistent with the second code value means that the first code value is consistent with the second code value or that the first code value matches the second code value. For two-dimensional code images, the first code value can comprise numbers or letters, and for microscopic graphic unit images, the second code value is purely digital, so that when the first code value only comprises numbers, the correspondingly generated second code value can be consistent with the first code value; when the first code value contains letters, the letters in the first code value need to be converted according to a conversion rule (for example, the letters are converted into numbers, or the letters are deleted), and then a corresponding second code value which does not contain letters is generated, so that the first code value and the second code value are matched.
S130, performing first coding operation on the micro graphic unit image so as to endow the micro graphic unit image with the product traceability information of the finished canned product.
In general, product coding refers to a process of giving a carrier which can carry information and serve as a unique product identifier to a product or a product package and writing basic product information, traceability information and the like into the carrier, and the product coding is an important link in the traceability and anti-channeling application of the product. In this embodiment, the coding operation refers to a process of writing basic information, tracing information, and the like of a product into a carrier serving as a unique identifier of the product, and the first coding operation refers to writing tracing information of the product of the finished canned product into a micro-graphic unit image. The product traceability information refers to related information of the finished canned products, which has the traceability and channeling prevention functions, and comprises, but is not limited to, product basic information (such as product names, use instructions, ingredients, specifications, validity periods, production enterprises and the like), production information (such as production factories, production lines, production teams, production dates, product batches and the like), logistics distribution information and the like.
Typically, the product traceability information is stored in a certain address in the server, and the product traceability information of the finished canned product is given to the micro graphic unit image, that is, the product traceability information of the finished canned product is written into the micro graphic unit image, that is, the storage address of the product traceability information in the server is associated with the second product query link of the micro graphic unit image.
And S140, printing the coded microscopic graphic unit image on the first preset position of the finished canned product through a invisible ink code spraying process.
Specifically, the invisible ink code spraying process refers to the use of invisible ink for printing, for example, infrared invisible ink with specific wavelength can be used for code spraying, so that the microscopic graphic unit images have good adhesiveness and strong concealment. The first preset position is a preset position of the spray-printed micro graphic unit image, for example, the first preset position is a position of a tank side wall of the finished canned product. The device for performing the spray printing operation is called a code spraying device, and the first preset position can be adjusted by adjusting the direction of the finished canned products on the production line facing the code spraying device. Optionally, a code spraying device with a code spraying resolution of not less than 300 x 300dpi (Dots Per Inch) should be used for the code spraying operation, preferably, the code spraying device should use a code spraying device with a code spraying resolution of 600 x 600dpi or more, and the size of the micro graphic unit image is 15 x 15mm or more, so that even if the micro graphic unit image is damaged in a large area, the information can be effectively read by the remaining 10% of the area (about 3 x 3 mm).
The microcosmic graphic unit images after coding are sprayed and printed at the first preset position of the finished canned products through the invisible ink coding process, so that the sprayed and printed microcosmic graphic unit images are invisible to human eyes, the attractiveness of the existing patterns on the original finished canned products is not affected, the masking performance is achieved, the original patterns are not prone to being damaged by people, and the tracing and channeling prevention effects are enhanced.
The method for producing the traceable and anti-channeling code of the canned product provided by the embodiment of the invention ensures that the traceable and anti-channeling code of the canned product comprises two-dimensional codes (plain codes) and microscopic graphic unit images (secret codes) which are printed by using a invisible ink code spraying process, and the traceable and anti-channeling effect of the canned product is further enhanced and the safety of the canned product is improved through the combination of the plain codes and the secret codes. In addition, the production method of the traceable and anti-channeling code of the canned products can directly carry out the traceable and anti-channeling processing on finished canned products which are processed, so that the application of the traceable and anti-channeling technology on imported finished canned products is greatly expanded, and the efficiency and accuracy of the inspection of the finished canned products in channeling are improved.
Example two
Fig. 2A is a schematic flow chart of a method for producing a traceable anti-channeling code for canned products according to a second embodiment of the present invention, which is a further refinement of the foregoing embodiment. As shown in fig. 2A, the method for producing the traceable and anti-channeling code for the canned product provided by the second embodiment of the present invention includes:
s210, sticking a two-dimensional code label at a second preset position of the finished canned product.
Specifically, the two-dimensional code label refers to a printed matter including a two-dimensional code for identifying related instructions of canned products, and a printing factory specially producing the two-dimensional code label is provided, so that the two-dimensional code label can be produced in advance by the printing factory and then stuck to a finished canned product. The second preset position refers to a position on the finished canned product, where the two-dimensional code label is visible to human eyes, so as not to affect the can body pattern and the aesthetic property of the original finished canned product, and the second preset position may be a position on the finished canned product that is hidden or a position that does not affect the can body pattern of the original finished canned product, for example, the second preset position is a can bottom position of the finished canned product.
Further, pasting the two-dimensional code label can be accomplished through automatic labeling machine, places finished canned product tank bottoms up on automatic circulation's production line, and when finished canned product flowed through automatic labeling machine, automatic labeling machine just can paste the two-dimensional code label in the bottom of finished canned product from the top. Optionally, in order to better collect the two-dimensional code image information later, the two-dimensional code image size on the two-dimensional code label is 15 x 15mm best, and is generally not lower than 10 x 10mm.
In an alternative embodiment, attaching the two-dimensional code label at the second preset position of the finished canned product may be replaced by: and engraving a two-dimensional code image at a second preset position of the finished canned product. The two-dimensional code image can be directly engraved on the finished canned product through the laser engraving machine, a label is not required to be stuck, paper is saved, and the method is more environment-friendly.
S220, acquiring the two-dimensional code image information on the two-dimensional code label.
And S230, if the acquisition is successful, performing a second coding operation on the two-dimensional code image on the two-dimensional code label so as to endow the two-dimensional code image with the product traceability information of the finished canned product.
Specifically, the step of acquiring the two-dimensional code image information refers to identifying a first product query link and a first code value of a two-dimensional code image through a special two-dimensional code acquisition camera. The acquisition of two-dimensional code image information needs to use special acquisition device, such as a two-dimensional code acquisition camera. When the two-dimensional code acquisition camera can acquire a first product query link and a first code value of the two-dimensional code image, the acquisition is successful, otherwise, the acquisition fails, and the two-dimensional code image may be damaged or the two-dimensional code label is not pasted in place.
For the two-dimensional code image before successful acquisition, at this time, the first product inquiry link is not usually associated with any product information, which is equivalent to that the two-dimensional code is null and does not store any real-time content, so that the two-dimensional code image information needs to be acquired, a second coding operation is performed on the two-dimensional code image, and the product tracing information of the finished canned product is endowed to the two-dimensional code image, namely, the first product inquiry link of the two-dimensional code image is associated with the storage address of the product tracing information in the server. Only through coding operation, the product tracing information of the finished canned product can be obtained when the two-dimension code image is scanned.
S240, if acquisition fails, entering a first exception handling flow.
Specifically, the failure in acquisition refers to that any one of the first product query link and the first code value of the two-dimensional code image cannot be acquired by the two-dimensional code acquisition camera, and the reason for the occurrence of such a situation may be that the two-dimensional code image is damaged or the two-dimensional code label is not pasted in place, for example, the two-dimensional code label of the automatic labeling machine is not replaced in time after being used up, so that the finished canned product on the production line is not pasted with the two-dimensional code label although flowing through the automatic labeling machine, and the two-dimensional code image information cannot be acquired naturally. If the acquisition of the two-dimensional code image information fails, the finished canned product with the failed acquisition of the two-dimensional code image information can be placed into a first exception handling area through the removing device and enter a first exception handling flow, so that the acquisition of the two-dimensional code image information can be successful.
Further, as shown in fig. 2B, the first exception handling flow includes steps S241 to S243.
S241, acquiring the two-dimensional code image information on the two-dimensional code label again through a two-dimensional code handheld scanning gun.
Specifically, for the finished canned product with failed acquisition of the two-dimension code image information, a worker can determine whether a two-dimension code label is stuck on the finished canned product through visual inspection, if the two-dimension code label is not stuck on the finished canned product, the finished canned product can be put back to the production line again, so that the step S210 is performed again to stick the label. If the two-dimensional code label is stuck on the finished canned product, a worker can scan the two-dimensional code image on the two-dimensional code label through the two-dimensional code handheld scanning gun, and the two-dimensional code image information is acquired again.
