    Description
    Title of the invention: ONLINE DATA VALIDOR OF A PRINTING UNIT
    The invention relates to a data validator of a printing unit, and more particularly to a compact two-dimensional on-line data validator covering an integrated printing and verification system for measuring and correcting a print quality of bar code.
    [0002] Products often include coded labels, such as barcodes, that can be used to identify and track products in stores, supermarkets, warehouses, and other commercial and industrial products. Currently, barcodes have become an important requirement in the commodity supply chain of various industries, and have received a lot of attention in payments, finance and consumer services. Stationary or mobile bar code scanners may be used to read the barcode image data and report the contents of the barcode to the outside through an output of a dice unit. printing for analysis and processing as a verifier or validator. In general, the verifier is used to measure bar codes (bar width / space, black / white contrast and other parameters) and to evaluate bar codes (quantifiable value based on measurement data); in addition, the validator also has the functions to validate barcodes and compare read data with the expected printed data. The two-dimensional in-line data validator (0DV2D) of the present invention measures and evaluates bar codes as the verifier but does not need to be strictly limited by all aspects of the ISO 15426 verifier requirements. Code technology An existing online bar that is integrated into print units and is available on the market today has the following problems.
    [0003] First, an existing technology can use third bar code scanners (or readers) mounted on the front of the printing unit. Some autonomous scanning device technologies do not measure or evaluate bar codes, they can only read bar code values. In addition, the complementary module approach often leads to performance limitations such as printing the entire label before scanning, restricting the location at which the bar code is to be printed on the label so that it is It can be scanned, long setup procedures to identify barcode locations for each new label, and there may be limitations in being able to save and overprint a label when a non-barcode readable is detected.
    [0004] Secondly, existing technology can use single point-of-row (CDD) contact scanning devices (charge coupled device) that are mounted in front of the printing unit. This technology requires label contact that can lead to accumulated dirt and debris from the print unit power supplies, and thus impact bar code measurement and evaluation. The ability to integrate with the target print unit will depend on the print unit performance capabilities and necessary interfaces that could impact the ability to perform certain functions such as overprinting of labels. In addition, this technology may require a laptop or external desktop computer to process the data, which not only adds cost but also increases system clutter.

    The following new technologies associated with this invention provide capabilities that are otherwise unavailable in the market today.
    The on-line data validator according to the present invention is fully integrated into the target print unit system to reduce clutter and enable features such as backup and overprinting of labels with bad bar codes.
    The target printing unit system according to the present invention is capable of extracting the location of the barcodes when the host data stream is processed and providing these locations and symbols to the validator of the present invention. online data in advance to alleviate the need for static time-consuming identification and configuration procedures.
    The on-line data validator of the present invention can scan, measure and evaluate 1D (one-dimensional) barcodes in both palisade and ladder orientation as well as 2D barcodes.
    The on-line data validator according to the present invention is mounted remote from the printed label and thus does not capture dirt and debris from the labels, and facilitates easy loading of media and ribbon, and different technologies. printing (such as thermal, inkjet or laser).
    The on-line data validator of the present invention scans the label when it is printed to create data tapes representing the printed format, and thus is not forced to "see" the entire label before measurement and evaluation.
    On the basis of the above new technologies, the on-line data validator according to the present invention can particularly provide many advantages, such as: [0034] The online data validator according to the present invention provides a new technology for online barcode verification when used with thermal or other printing technologies. The purpose of the system is to measure, report, and serve to enable printing units to self-correct bar code print quality problems. The benefits of an on-line barcode verification system on a printing unit are documented in US Patent No. 6,535,299.
    The on-line data validator according to the present invention provides a concept of folded mirrors causing the mirrors to form a folded optical path which allows the validator to be mounted closer to the printed label and economically produced in a very small volume.
    The on-line data validator of the present invention provides a low cost means for generating high intensity illumination sources from a network of low cost light sources, such as LEDs (light emitting diodes). ), for controlling the driving of the light sources so as to compensate for an illumination variance in the imaging system, for controlling the spatial distribution of light sources so as to produce a uniform illumination field due to their position in the network, and to use low cost optical elements to further smooth illumination across the field of view, to overcome typical illumination sources that do not inherently produce uniform illumination without additional optics and often complex (expensive) and unstable over time.
    The on-line data validator according to the present invention provides its own integrated control device which is dedicated to processing the scanned data and sending the results to the printing unit, to overcome the existing technology that can Require a laptop or external desktop computer to process the data.
    The on-line data validator according to the present invention attached to the front of the printing unit not only provides the ability to read bar code data but also to eliminate the accumulation of dust or dirt and thus will not impact a bar code measurement and evaluation, overcoming the existing technology with which the scan head makes direct contact with the printed label, and then, any excess paper dust or any adhesive may be deposited on the scanning head. This or this in turn prevents the sensor elements from reading data from the tag and prevents barcode validation.
    The on-line data validator according to the present invention provides an extension of an existing capability to ID ladder barcodes and 2D barcodes, to overcome the existing printing and code verification technology to bars that is based on a verification instrument and can only check for ID palisade barcodes.
    The on-line data validator according to the present invention applies a high-speed digital image acquisition system by using a camera technology whereby a narrow image (nominally of a width of 10 pixels) is synchronously taken with the print unit motor driver (which moves the labels through the print station). These narrow images (or tapes) are buffered and processed in real time when the image is captured. This means that the analysis occurs during printing rather than waiting for the entire label to be printed.
    [0041] The online data validator according to the present invention provides a function of reconstructing subframe images in line from a moving target by synchronously taking narrow images (nominally of a width of 5 μm). pixels or 10 pixels) with a paper movement and sending to a buffer where the entire printed image is reconstructed in the binary image of a label. When the image is built, the software scans the image for barcodes, regardless of their type or orientation, to overcome the existing technology that requires printing the entire label before scanning and limits the location of printing and scanning.
    The on-line data validator of the present invention provides a coordinate tracking instruction system with the printing unit controller which examines the incoming data for each bar code printing instruction comprising information such as barcode type, barcode data and point coordinates. In addition to printing instructions, incoming graphic images are analyzed to determine which bar codes are present and where they are located. Once collected, the information is sent to the online data validator control device to search for a bar code and which barcode data should be here, to solve the problem that it takes a long time to process programs. identification and tuning in which the type of bar code, data and coordinates are unknown.
    In addition, by application of the present invention, bar codes can be printed in any orthogonal orientation (with respect to the printing direction), and can still be detected, measured and compensated for print quality. on the basis of an auditor's instrument.
    To better illustrate the object of the present invention will be described below, by way of illustration and not limited to, a preferred embodiment, with reference to the accompanying drawings.
    In these drawings: [0046] [fig.l] is a schematic diagram of a sectional view of a printing unit with an on-line data validator according to a preferred embodiment of the present invention, and [0047] [Fig. 2] is a schematic diagram of a sectional view of the on-line data validator of Fig. 1 according to the present invention.
    The present invention provides an on-line data validator 2 to fully integrate into a printing unit 1 which may be a thermal printer used in US Patent No. 6,535,299 or other commercially available printers. such as an inkjet printer or laser printer, to print barcodes.
    Referring to Figure 1, it can be seen that there is shown a schematic diagram of a sectional view of a printing unit 1 with the online data validator 2 according to the preferred embodiment of the present invention. The on-line data validator 2, via a medium 5, is mounted on the printing unit 1 with screws (not shown) inserted at mounting holes 51 in the holder 5 disclosed in the original US Pat. No. 6,535,299 and integrated on the front side of the printing unit 1. An output 56 of the printing unit 1 is installed on the same side near the on-line data validator 2 such that a scan line beam 59 issued by the on-line data validator 2 scans the width of a tag 32 on a scan target 70 near the output 56 for bar code verification. The tag 32 (such as 1D barcodes in both palisade and ladder orientation, 2D barcodes, and other targets), for example, may be formed from a support 16 (such as paper, plastic or other materials). When the support 16 which is provided by a coil 10 and a heat-sensitive printing ribbon 46 which is provided by a coil 42 passes over a thermal print head 54 from a turntable 57, the printed label 32 is formed on the support 16.
    [0050] The printing modes of the thermal printer usually use thermal transfer printing technologies, meaning that a material with a specific formulation is used to form the printed image on the label 32 as a result of Heat pulses from the print head 54. One of the print modes may use the ribbon 46 with a wax / resin, all-wax, or entirely heat-sensitive resin formulation. An alternative printing mode supported by the same system of the printing unit 1 is a direct thermal printing which uses the support 16 with dyes impregnated in the fibers of the support 16, and which become black when heated. In this printing mode, the printing unit 1 can play the same effect without the use of the ribbon 46.
    Referring to Figure 2, it can be seen that there is shown a schematic diagram of a sectional view of the online data validator 2 in Figure 1 according to the present invention. The on-line data validator 2 is a digital imaging system integrated on the front side of the printing unit 1, the output 56 of the printing unit 1 being installed on the same side near the validator of online data 2 for printed label images 32 on a medium 16 emerging therefrom. The output 56 may further include limiters 12 such as rollers or bars to constrain the printed labels 32 near the scanning target 70 to improve scan accuracy.
    The on-line data validator 2 comprises a control device 20, a camera comprising optical components of a camera module 30 and a mirror module 40, a light source module 50 and a loudspeaker 60. The camera module 30 comprises a sensor PCB 31 and an optical lens 35, the sensor PCB 31 containing a camera sensor 33. The optical lens 35 is disposed between the camera sensor 33 and the camera sensor 33. mirror module 40. The mirror module 40 comprises two mirrors disposed between the camera module 30 and the light source module 50. The light source module 50 comprises a light bar 52, a light bar PCB 53, a Fresnel lens 55 and a transparent element 58. The enclosure 60 has a window 61 at a distance closest to the output 56 of the printing unit 1.
    The controller 20 facilitates communication with a print unit controller 24 (refer to Figure 1) which dominates the overall operation of the print unit 1 and controls the operation of the functions. The controller 20 groups data from the camera sensor 33, controls the stroboscopic effect of the light bar 52, finds, decodes, and evaluates the bar codes embedded in scanned data at a time. from the camera sensor 33, and send back results to the printing unit 1. The camera sensor 33 of the camera module 30 is a high-speed 2D digital imager for taking pictures of the printed labels 32. The optical lens 35 of the camera module 30 receives the scanned image from the printing unit print line 1 and converts the resolution to be compatible with the camera sensor The mirror module 40 reflects the scanned image of the scanning line 39 to the optical lens 35, allowing a reduced-space enclosure 60.
    The light source module 50 provides internal light sources illuminating the scanning target 70 on the support 16 leaving the output 56. The light bar 52 electronically connected to the lightbar PCB 53 of the source module. The light 50 provides illumination necessary to ensure proper scanning of the printed labels 32. The Fresnel lens 55 of the light source module 50 is placed between the light bar 52 and the transparent member 58 within the enclosure 60 and is used to channel the stray light sources into a narrow, uniform scanning line beam 59 directly on the scanning target 70. The transparent element 58 seals the window 61 of the enclosure 60 and may be made of glass or other transparent materials, which allows the scanning line beam 59 and incoming graphic images to pass but prevents a contaminant from entering the coatings. Optical components of the camera and that may otherwise impact the evaluation. The enclosure 60 receives the controller 20, the camera module 30, the mirror module 40 and the light source module 50 therein, which uses a support 5 with screws inserted at mounting holes. 51 for integration on the printing unit 1.
    This invention relates to digital imaging systems that need to be calibrated for absolute reflectance values over a field of view. Such systems need to have a high degree of control over the illumination source and it is highly desirable to have the illumination as uniform as possible over the field of view. Typical illumination sources do not inherently produce uniform illumination without additional and often complex (expensive) optics. In addition, some sources of illumination are not stable over time. This invention creates an illumination source from a network of low cost light sources, such as LEDs, for controlling the control of the light sources so as to compensate for a variance of illumination in the system due to their positions in the network, and to use low-cost optical elements, such as the Fresnel lens 55, to further channel and flatten the network of the spatial distribution of LED light sources in a narrow scan line beam, The light bar 52 of the light source module 50 becomes the LED array forming a LED light bar electronically connected to an LED light bar PCB.
    A shading cover 45 is installed around the light bar 52 as an illumination guide to ensure that the scanning line beam 59 on the scanning target 70 directly through the Fresnel lens 55 does not interfere with the scanned images of the scanning line 39 to the optical lens 35.
    The light source module bar 50 of light source 50 is electronically connected to the control device 20. Thus, the stroboscopic effect of the light bar 52 can be synchronized with the camera sensor 33 and managed by the device as a master.
    The mirror module 40 comprises a first mirror 40a and a second mirror 40b shown in FIG. 2 to illustrate a concept of folded mirrors. The two mirrors are arranged with their reflection surfaces facing each other obliquely so as to ensure that the images of the printed labels 32 scanned from the scanning target 70 on the mobile support 16 emerging from the output 56 after being reflected by these two mirrors are directed through the optical lens 35 to the camera module 30. On the basis of the requirement that the optical lens 35 is to be directed to the reflection direction of the second mirror 40b, the relative position and orientation of the camera module 30 with respect to the mirror module 40 depends on those of the arrangement of the two mirrors. An embodiment shown in Figure 2 indicates that the image of the tag 32 on the carrier 16 is reflected from the first mirror 40a to the second mirror 40b and then reflected through the optical lens 35 and into the camera sensor 33 of the camera. camera module 30 oriented vertically to improve compactness in the longitudinal direction. As a result, the mirror module 40 is located between the camera module 30 and the light source module 50. The same concept can also be applied to the situation that requires more than two mirrors. In this way, the mirror module 40 of the camera comprises at least two mirrors, the optical lens 35 being oriented towards the direction of reflection which is finally emitted from the mirror module 40. Thus, a folded optical path formed in the mirror Mirror module 40 allows online data validator 2 to be designed to be mounted closer to the printed label 32 and economically produced in a small volume. Compared to existing technology such as US Patent No. 6,535,299 which requires the tester to be mounted 8 inches from the printed label 32, the compactness of the present invention allows the online data validator 2 to be designed to be mounted about 3 inches from the printed label 32.
    As a result, the optical lens 35 of the camera module 30 and the mirror module 40 work together to direct the image of the printed label 32 to the camera sensor 33, while the media 16 leaves the output 56 of the printing unit 1. The camera sensor 33 of the camera module 30 is electronically connected to the sensor PCB 31, which is a 2D image sensor processor for transforming the image received by the image sensor. camera 33 in computer readable information. The camera sensor 33 may be a CMOS image sensor (semiconductor complementary to the metal oxide) or other commercial products. The computer-readable information is then sent to the controller 20 and used for checking whether or not correct information is printed on the medium 16. The optical lens 35 converts the resolution of the image to be compatible with the camera sensor 33 of the camera module 30.
    The folded optical path formed in the mirror module 40 makes the on-line data validator 2 fully integrated into the printing unit 1, reducing the overall size and allowing features such as backup and overprinting of the images. printed labels 32 with wrong barcodes, where the barcode is not recognizable as a barcode, or where the data encoded in the barcode is incorrect compared to the data sent to the printer, or the The barcode has ratings that are lower than operator-configured thresholds, or the barcode has dimensional parameters below thresholds set by the barcode standards. The printing unit 1 is able to extract the location of the barcodes when the host data stream and / or a graphic are processed and to provide these locations and symbols to the online data validator 2 to in advance to relieve the need for static time-consuming identification and configuration procedures. Thus, the online data validator 2 can scan, measure and evaluate ID barcodes in both palisade and ladder orientation as well as 2D barcodes. In addition, the on-line data validator 2 is mounted remote from the printed labels 32 and thus does not capture dirt and debris from the label 32 and facilitates easy loading of the ribbon 46 and the holder 16, and different technologies. printing (such as thermal, inkjet or laser). Finally, the on-line data validator 2 scans the tag 32 when it is printed to create data tapes representing the printed format, and thus is not constrained to have to see the entire tag 32 before measurement and evaluation.
    This invention relates to digital imaging systems that require precise alignment of the imager (i.e., the 2D digital camera sensor 33) on the targets (i.e., the labels 32) to be imaged. For such systems, it is often necessary to position the camera sensor 33 at a precise location in three dimensional axes as well as to control the pitch, roll, and yaw of the camera sensor 33 around the three axes. To be economically viable, this process needs to be easy for the operator to achieve, to quickly get the focus requirements of the system and to lead to a system that is stable over time. This invention teaches a method of obtaining the desired alignment of the imager on tag 32 scanned from scan target 70 by a two-step process, the first step being the internal alignment of optical components of the camera and the second step being the mechanical alignment of the camera on the label 32.
    Specifically, the first step, in one embodiment, is to manually configure the mirror alignment using adjustment screw adjustments based on an image processing system and an image processing equipment. alignment to provide feedback to the operator on real-time alignment status. In another embodiment, the alignment is automatically adjusted using closed-loop servo control techniques.
    The second step is to configure the camera alignment on the label 32 by means of a mounting bracket 5 with adjustment screw adjustments that control the pitch, yaw and roll of the camera relative to the camera. This technique can also be further optimized by using the closed-loop servocontrol described in the first step.
    The online data validator 2 comprises a verification system from which users of the printing unit 1 can see in real time whether or not the desired information has been correctly printed on the medium 16. The verification starts with the camera which is initiated to capture the image on the medium 16 coming out of the output 56 of the printing unit 1. The image of the scanning target 70 is then analyzed to see if the medium 16 represents or not the correct label 32.
    Specifically, the verification system can extract the correct bar code information from the database and compare it to the image received by the camera sensor 33 of the camera module 30. If there is a match, then the printing unit 1 will retain the impression, on the contrary, if the verification system finds that the information printed on the medium 16 is incorrect or does not satisfy the international bar code standard, the Targeted area of support 16 will be marked and it will be implemented a backup and overprint of the labels 32 with the wrong bar codes.
    While the preferred embodiments of the invention have been presented for the purpose of disclosure, they are not the limitations of the invention, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may come to the mind of those skilled in the art.
