Detailed Description
The principles and features of the present application are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the application and are not to be construed as limiting the scope of the application.
The embodiment provides a marking device, and marking identification codes are marked on an aluminum foil (aluminum film) and a tinned sheet by adopting the marking device, so that the purposes of facilitating consumer identification and anti-counterfeiting are achieved.
Referring to fig. 1-2, the marking device provided in this embodiment may be understood as a marking assembly line, and the marking assembly line specifically includes a conveying line 100, and a first marking machine 10, a first visual inspection machine 20, a laminating machine 30, a second marking machine 40, and a second visual inspection machine 50 are sequentially disposed beside the conveying line 100.
The first marking machine 10, the first visual inspection machine 20, the laminator 30, the second marking machine 40, and the second visual inspection machine 50 here are sequentially arranged along the transport direction of the transport line 100, so that the upper cover of the milk container (finished product of tin-plated sheet and aluminum film) is finished.
In this aspect, the first marking machine 10 is provided configured to enable simultaneous inscription of the inner code and the proof mark on the tin-plated sheet; i.e. the tinplate is transported to the position of the first marking machine 10, the first marking machine 10 marks both the inner code and the calibration mark on the surface of the tinplate according to preset information requirements.
The first visual inspection machine 20 is configured to simultaneously inspect the internal code and the calibration standard on the tin-plated sheet to determine whether the internal code and the calibration standard are of a preset same specification; the calibration mark is a string of characters, a pair of digital combinations or a section of letter combinations which are internally formulated and have relevance to the internal code, and can also be a bar code or a two-dimensional code, and the first visual inspection machine 20 detects whether the internal code and the calibration mark of the mark accord with the preset or not and whether errors occur or not.
Optionally, the calibration marks are marked in a manner which is not easily perceived by human eyes, namely, the naked eyes cannot directly and intuitively see the calibration marks marked on the tinned sheet; but the calibration standard will be very easily detected under the detection of an industrial vision detector.
The laminator 30 is configured to attach an aluminum film to the tin-plated sheet and to cause the internal code in the tin-plated sheet to be covered and the calibration standard to be exposed; the mode of coating is the key point in the application, and in order to achieve the anti-counterfeiting purpose, the inner code in the tinned sheet is covered by the aluminum film so that the inner code is hidden; thus, only if the aluminum film is torn off, the internal code is displayed; the consumer can also effectively verify by checking the inner code.
The second marking machine 40 is configured to inscribe an external code identical to the internal code information on the external surface of the aluminum film; and the second vision inspection machine 50 is configured to simultaneously inspect the external code on the aluminum film and the calibration standard on the tin-plated thin plate, and to perform the correlation comparison of the external code and the calibration standard.
The upper cover (the finished products of the tinned sheet and the aluminum film) of the final milk tank presents an external code to the outside, a consumer can verify the source of the external code, and in order to prevent the product from being a counterfeit product, the consumer respectively detects the external code and the internal code after tearing off the aluminum film and judges whether the presented information is the same; if the information is the same, the source quality is normal, and if the information is different, the product can be considered to be counterfeit.
The provided calibration marks are important marks for connecting whether the information of the outer code and the information of the inner code are consistent, and refer to fig. 2-3, because in the processing of the scheme, if the calibration marks are not provided, the second visual inspection machine 50 can only detect the outer code under the condition that the inner code is covered by an aluminum film, and in the production process, whether the information of the inner code and the information of the outer code are the same or not can not be judged, and whether the outer code is wrought or not is wrong or not; thus assisted here by the use of calibration marks; namely, the first marking machine 10 marks the external code and the calibration mark in the tinned sheet at the same time, the first visual inspection machine 20 detects whether the external code and the calibration mark have marking errors, and if no error exists, the calibration mark at the moment becomes the key for associating the external code with the internal code; the film laminating machine 30 is used for covering the aluminum film on the tinned sheet and completely shielding the internal code, the calibration marks at the moment are still in an exposed state, and after the second marking machine 40 is used for marking the external code on the aluminum film, the second visual inspection machine 50 can be used for simultaneously verifying the external code on the aluminum film and the calibration marks on the tinned sheet; by the scheme of the calibration standard, the information between the inner code and the outer code before the product leaves the factory has strong correlation, so that the external counterfeiting is effectively avoided, and the anti-counterfeiting verification accuracy is further improved.
Optionally, a stamping press 60 is further included, where the stamping press mainly processes the tin-plated sheet, and the stamping press 60 is located beside the conveyor line and in a station before the film coating machine 30, where the stamping press 60 is configured to perform a horse-cut stamping on the tin-plated sheet, i.e. the stamping process should be performed before the film coating process is performed on the tin-plated sheet.
In this embodiment, a marking die is provided on the conveyor line 100, and a tin-plated sheet may be placed in the marking die to gradually complete the inscription of the inner code, the calibration mark, and the attachment of the aluminum film. Specifically, the marking die comprises die cavities 101 arranged side by side, each die cavity 101 comprises an outer groove and a horse-head groove, the outer grooves are round, and the horse-head grooves are positioned at the bottoms of the outer grooves and are recessed downwards.
The following describes the detailed steps for marking with the present device, see fig. 4:
s1, blanking.
S2, starting up the first marking machine 10 and selecting a corresponding marking template, wherein product information to be marked is recorded in the marking template.
And S3, starting transportation of the whole conveying line, and when the tinned sheet is transported to the lower part of the first marking machine 10, carrying out internal code and calibration marking on the tinned sheet in the die cavity 101 by the first marking machine 10, wherein the specific marking position is that the internal code is marked on the middle lower position of the tinned sheet, and the calibration marking is marked on the edge of the tinned sheet.
S4, detecting the tinned sheet in the step S3 by adopting a first visual detector 20, wherein the detected content comprises whether the carved internal code and the calibration mark are accurate or not, and detecting that the internal code and the calibration mark have associated preset corresponding specifications; if the detection is OK, the next station is released; if any problem occurs in the detection, the tinned sheet is directly selected into a waste removing station.
S5, enabling the qualified tinned thin plate to flow into the position of the film laminating machine 30, attaching an aluminum film on the tinned thin plate by the film laminating machine 30, wherein the specific attaching position is shown as follows: the inner code on the tinned sheet is completely covered by the aluminum film, and the calibration standard is normally exposed.
S6, enabling the coated tinned sheet to flow into the position of the second marking machine 40, and marking an external code at the center of the aluminum film by the second marking machine 40, wherein the external code information is required to be completely consistent with the coated internal code information.
S7, the second visual inspection machine 50 detects the tinned sheet finished in the step S6, and detects whether the presented external code and the information displayed by the calibration standard are completely consistent with the information displayed by the internal code and the calibration standard in the step S3; if the marking is consistent, finishing marking and carrying out the next process; if the tin plating thin plates are inconsistent, the tin plating thin plates are directly selected into a waste material removing station.
Optionally, before the coating in step S5, that is, before the coating machine 30 attaches the aluminum film to the tin-plated sheet, there is a step of performing a horse-cut stamping on the tin-plated sheet, which may be between any of steps S2 to S4.
In this embodiment, the stamping operation is preferably placed between steps S1-S2, or between steps S4-S5; the impact of stamping on marking detection is reduced.
Of course, in the above operation steps, we also propose a second set of processing steps scheme, which is different from the scheme described above in terms of the main difference, in that the process steps after completion of step S4, we can replace the steps of S5 to S7 described above with the steps of S5-1 to S7-1 below, in particular as follows, see fig. 5:
s5-1, independently setting a second marking machine 40, providing an aluminum film for the second marking machine 40, and engraving an external code on the center position of the aluminum film in advance by the second marking machine 40, wherein the external code information is completely consistent with the internal code information of the tinned sheet.
S6-1, enabling qualified tinned sheets to flow into the position of the film laminating machine 30, and enabling the film laminating machine 30 to attach the aluminum film carved with the external codes in the step S5-1 to the tinned sheets, wherein the specific attaching position is shown as follows: the inner code on the tinned sheet is completely covered by the aluminum film, while the outer code on the calibration standard and the aluminum film is normally exposed.
S7-1, detecting the tinned sheet finished in the step S6-1 by a second visual detector 50, and detecting whether the presented information of the external code and the calibration standard is completely consistent with the information of the internal code and the calibration standard in the step S3; if the marking is consistent, finishing marking and carrying out the next process; if the tin plating thin plates are inconsistent, the tin plating thin plates are directly selected into a waste material removing station.
The second scheme (the outer code is firstly engraved and then the aluminum film is attached) is adopted for marking, so that the same product effect as the first scheme (the aluminum film is firstly attached and then the outer code is engraved) is generated.
According to the technical scheme, the method for synchronously marking the inner code and the calibration mark on the tinplate (tinplate) and marking the outer code on the aluminum foil is adopted. The anti-counterfeiting code is automatically generated and encrypted through the data of the inner code and the calibration standard, and then the calibration standard is compared with the outer code to form the association of the inner code and the outer code, so that the problems of difficult verification and anti-counterfeiting are fundamentally avoided.
The foregoing description of the preferred embodiments of the application is not intended to limit the application to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the application are intended to be included within the scope of the application.
