Description

  The present invention mainly relates to an environmental history display for managing environmental conditions during transportation and storage, transportation of data, storage, a data reading processing apparatus for processing the display data, a data reading processing method, and The present invention relates to a quality control method and a quality control system for articles.

  Some articles that are transported from the manufacturing location to the consumption location require appropriate management of environmental conditions such as temperature, humidity, vibration, gas, and atmospheric pressure. For example, there are foods that become unconsumable due to spoilage or changes in taste when placed in a high or low temperature environment. In addition, there are foods in which quality degradation occurs when placed in a high humidity environment or in an environment where oxygen at atmospheric level exists. In addition, there is an article that breaks when a vibration more than expected is applied.

  In order to manage properly under such conditions, when transporting and storing the target items, define the management range and transport it using an air conditioner that is put in a sealed container to fit within the range Measures such as temperature management, humidity management, and vibration management of containers, transport trucks and storage rooms are implemented.

  However, there is a case where the management range is deviated due to a failure of the apparatus or a management leak. In order to determine whether or not a deviation has occurred, there are the following apparatuses and methods.

  Patent Document 1 discloses a method in which a temperature indicating member that changes color according to temperature is applied to an article to be managed, and a code represented by an adjacent barcode and a color of the temperature indicating member are read by a reading device. Furthermore, a method for estimating the temperature history by analyzing the read code and color data is disclosed. A method for realizing a temperature indicating member that changes color depending on temperature is also disclosed.

JP 2001-91368 A

  In the method disclosed in Patent Document 1, the temperature history can be estimated by analyzing the read color data. Since an analysis is necessary to estimate the temperature history, it is difficult to grasp the temperature history just by visual observation and determine whether or not there is a deviation from the management range. In addition, the time of exposure to a specific temperature environment is estimated using the intensity of reflected light. For this reason, the intensity varies depending on the state of the ambient light such as the illumination of the color data reading place, and there is a possibility that the error of the estimation time is increased.

  An object of the present invention is to provide an environment history display object that can easily grasp a storage environment history including time.

  In order to solve the above problems, the environmental history display object according to the present invention is an environment history display object capable of determining whether or not there is a deviation from the management environment, and is a plurality of irreversibly discolored colors outside the set environmental range. There are a plurality of display units having the mark, and the plurality of marks have different times from the time when they deviate from the environmental range until they change color, and the environmental range is different for each display unit.

  According to the environmental history display object according to the present invention, it is possible to easily grasp the environmental history including time.

  Embodiments will be described below with reference to the drawings.

<Environmental history display>
FIG. 1 is a top view of the environmental history display object according to the first embodiment. The environmental history display object can determine whether or not there is a deviation from the management environment, and includes a plurality of display units (21, 22, 23,...) On the base material 1. Each display unit is composed of a plurality of environmental change marks that irreversibly discolor when they are out of the set environment range, and the plurality of environment change marks have different times until they change color from outside the set environment range. . For example, the display unit 21 includes a plurality of environment change marks (31a, 31b,...) That irreversibly discolor when outside the set environment range, and the display unit 22 includes the environment change marks (32a, 32b,. ...). In addition, the environment range set for the plurality of environment change marks differs for each display unit.

  In FIG. 1, the display unit is provided on the base material 1, but the display unit may be directly printed or pasted on an article such as a product without using the base material 1.

  In addition to the display section having the environmental change mark, the environmental history display object further includes a character string 41 indicating the temperature corresponding to the row, a character string 42 indicating the period corresponding to the column, an arrow and a character string indicating the difference in the vertical direction 43, an arrow indicating a difference in the horizontal direction and a character string 44 are displayed. Note that the character strings 41 to 44 are not essential. In FIG. 1, the environment change marks are arranged in 6 rows and 6 columns in the vertical and horizontal directions, but the present invention is not limited to this number of rows and columns.

  Hereinafter, the function of the environmental history display object using the environmental change mark that changes color due to temperature change will be described. In FIG. 1, the environment change marks 31a and 31b have the same environment (temperature) causing the color change, but have different time (sensitivity) from the time of reaching the temperature to the color change. The environment change mark 31a and the environment change mark 32a are different in the environment (temperature) causing the color change, but the time until the color changes after reaching the temperature is substantially the same.

  For example, when exposed to an environment of 26 ° C., a mark is set with a condition that the mark 32a changes color after 3 days and the mark 32b changes color after 4 days. In addition, when exposed to an environment of 26 ° C. for 4 days, the marks 32a and 32b and the mark below it change color, but the mark of the row of 30 ° C. and the mark of the columns of 6, 7, and 8 days do not change color.

  In this way, multiple marks that have different time to color change when exposed to the same temperature environment and multiple marks that cause the presence or absence of color change when exposed to the same temperature and different temperature environment coexist. Therefore, it is possible to grasp the quality deterioration state that combines the storage environment and time. As a result, by checking whether the environmental change mark is discolored, it is possible to manage the storage environment in combination with the expiration date (expiration date, etc.).

  In the present embodiment, a mark that changes color depending on temperature is used, but a mark that changes color depending on other environments such as humidity, vibration, pressure, etc. may be used. In this embodiment, an example in which marks are arranged in a matrix is shown, but the present invention does not limit the arrangement method. For example, an oblique matrix may be used, or a design that is not regular and combined with an illustration may be integrated.

  Hereinafter, the environment change mark will be described in detail.

(Environmental change mark)
The environmental change mark is made of, for example, a temperature indicating material (thermochromic ink or the like) that changes irreversibly when it deviates from a set temperature.

  The set temperature and the time from the departure from the set temperature to the color change can be adjusted, for example, by changing the type of the temperature indicating material for each mark. FIG. 2 shows an example of a cross-sectional view of the display unit. By using different temperature indicating materials 51, 52, and 53 for each environment change mark, the time until the color changes is adjusted. For example, when an ink containing a leuco dye, a developer, and a color erasing agent is used as the temperature indicating material, the time from deviating from the set temperature range to the color change depends on the type of color erasing agent and the addition to the ink. It can adjust by changing the quantity of an agent.

  The environment change mark may be composed of a temperature indicating material and a heat conductive layer. FIG. 3 is a cross-sectional view of a display unit including a heat conductive layer. The heat conductive layers 61, 62, and 63 are disposed between the temperature indicating material 50 and the base material 10, respectively. Although the same temperature indicating material is used for all marks, the thermal conductivity layers 61, 62, and 63 have different thermal conductivities. By disposing the heat conductive layers having different heat conductivities between the thermochromic ink and the base material in this way, it is possible to control the time from the departure from the set temperature to the color change at each mark.

  The time from the departure from the set temperature range to the color change may be adjusted by changing the thickness of the heat conductive layer. FIG. 4 shows a cross-sectional view of an environmental history display object in which the thickness of the heat conductive layer is changed. As shown in FIG. 4, in each mark, the temperature indicating material 50 and the heat conductive layer 60 are the same, but the thickness of the heat conductive layer is changed. The thicker the heat conductive layer, the longer the time from the departure from the set temperature range to the color change.

(Indication material)
As the temperature indicating material, it is preferable to use an ink composed of a leuco dye, a developer, and a decoloring agent. The leuco dye is composed of an electron donating compound, and conventionally known dyes for pressure-sensitive copying paper and heat-sensitive recording paper can be used. For example, triphenylmethane phthalide, fluoran, phenothiazine, indolyl phthalide, leucooramine, spiropyran, rhodamine lactam, triphenylmethane, triazene, spirophthalanthanthene, naphtholactam, An azomethine type | system | group etc. are mentioned. Specific examples of such leuco dyes include 9- (N-ethyl-N-isopentylamino) spiro [benzo [a] xanthene-12,3′-phthalide], 2-methyl-6- (Np -Tolyl-N-ethylamino) -fluorane 6- (diethylamino) -2-[(3-trifluoromethyl) anilino] xanthene-9-spiro-3'-phthalide, 3,3-bis (p-diethylaminophenyl) -6-dimethylaminophthalide, 2'-anilino-6 '-(dibutylamino) -3'-methylspiro [phthalide-3,9'-xanthene], 3- (4-diethylamino-2-methylphenyl) -3 -(1-Ethyl-2-methylindol-3-yl) -4-azaphthalide, 1-ethyl-8- [N-ethyl-N- (4-methylphenyl) amino] -2,2,4-trime Le-1,2-dihydro-spiro [11H-chromeno [2,3-g] quinoline -11,3'- phthalide and the like. Two or more leuco dyes can be used in combination.

  The developer that is an electron acceptor can be colored by changing the structure of the leuco dye by contacting with the electron-donating leuco dye. As the developer, a publicly known developer can be used for heat-sensitive recording paper or pressure-sensitive copying paper. Specific examples of such a developer include benzyl 4-hydroxybenzoate, 2,2'-biphenol, 1,1-bis (3-cyclohexyl-4-hydroxyphenyl) cyclohexane, 2,2-bis (3 -Phenols such as -cyclohexyl-4-hydroxyphenyl) propane, bisphenol A, bisphenol F, bis (4-hydroxyphenyl) sulfide, paraoxybenzoic acid ester, gallic acid ester and the like. The developer is not limited to these and may be any compound that is an electron acceptor and can change the color of the leuco dye. Also, metal salts of carboxylic acid derivatives, salicylic acid and salicylic acid metal salts, sulfonic acids, sulfonates, phosphoric acids, phosphate metal salts, acidic phosphate esters, acidic phosphate metal salts, phosphorous acids, phosphorous acid Metal salts and the like may be used. In particular, those having high compatibility with leuco dyes and decoloring agents described later are preferable, and organic developers such as 2,2′-bisphenol, bisphenol A, and gallic acid esters are preferable.

  Two or more of these color developers may be combined, and further, the color density at the time of coloration of the leuco dye can be adjusted by combining them. The amount of developer used is selected according to the desired color density. For example, what is necessary is just to select within the range of about 0.1-100 weight part with respect to 1 weight part of above-mentioned leuco pigment | dye normally.

  A decolorizer is a compound that can dissociate the bond between the leuco dye and the developer, and is a compound that can control the color temperature between the leuco dye and the developer. Generally, in the temperature range in which the leuco dye is colored, the decolorizer is solidified in a phase-separated state. Further, in the temperature range where the leuco dye is in a decolored state, the decolorizer is melted and a function of releasing the bond between the leuco dye and the developer is exhibited. The coloring and erasing temperature of the leuco dye used in the ink of the present invention depends on the freezing point and melting point of the erasing agent. Therefore, it is desirable that there is a temperature difference between the freezing point and the melting point of the decolorizer. Further, the melting point or the temperature of the freezing point depends on the target temperature management range. Specifically, there are fatty acid ester compounds such as isopropyl myristate, isopropyl palmitate, tricaprylin, tricaprin, trilaurin, and trimyristin, and these compounds are included from the viewpoint of compatibility with leuco dyes and developers. Is preferred. Two or more of these decolorizers may be combined, and in this case, the freezing point and the melting point can be adjusted. Of course, it is not limited to these compounds, For example, other ester, alcohols, ethers, ketones, amides, azomethines, fatty acids, hydrocarbons etc. can be mentioned.

  The present invention does not limit the type and configuration of these materials and penetrants, and any material that changes color with a change in temperature may be used.

  Inks containing leuco dyes, developers, and decolorizers can be used by uniformly dispersing in inks, paints, synthetic resins, etc., as with normal dyes and pigments. It is desirable that they are independently encapsulated by microcapsules made of a resin film. By microencapsulating, as described above, environmental resistance to humidity and the like of the composition is improved, and storage stability, discoloration characteristics, and the like can be achieved. In addition, it is possible to suppress the influence of the leuco dye, the developer, and the color erasing agent from other resin agents, additives, and the like when the ink is prepared into an ink or a paint by microencapsulation.

  Various known techniques can be applied to the microencapsulation. For example, an emulsion polymerization method, a suspension polymerization method, a coacervation method, an interfacial polymerization method, a spray drying method and the like can be mentioned, but the invention is not limited to these. Two or more different methods may be combined.

  Resin coatings used for microcapsules include urea resin coatings composed of polyamines and carbonyl compounds, melamine / formalin prepolymers, methylol melamine prepolymers, melamine resin coatings composed of methylated melamine prepolymers, polyisocyanates and polyol compounds. Urethane resin coatings, amide resin coatings composed of polybasic acid chlorides and polyvalent amines, vinyl-based resin coatings composed of various monomers such as vinyl acetate, styrene, (meth) acrylic acid esters, acrylonitrile, and vinyl chloride. However, it is not limited to these. Furthermore, additional treatments such as improving the dispersion stability of the microcapsules can be performed by performing a surface treatment on the formed resin film and adjusting the surface energy when forming ink or paint.

  The diameter of the microcapsule is preferably in the range of about 0.1 to 100 μm, more preferably in the range of 0.1 to 1 μm, because apparatus compatibility, storage stability, and the like are problems.

  When printing ink using a charge control type ink jet printer, an ink solution in which the ink is dispersed in a solvent is required. The ink solution contains a resin, a colorant, an additive having a polydimethylsiloxane chain, an additive having an alkoxysilane group, a solvent, and the like, and these materials are stirred with an overhead stirrer or the like to dissolve or disperse each other. Is formed. When the ink resistance is high, a conductive agent described later is also added.

  Further, it is preferable to add a conductive agent to the ink solution. When the resistance of the ink solution is high, the ink particles do not fly straight but tend to bend at the ink ejection portion in the charge control type ink jet printer. Therefore, the resistance needs to be approximately 2000 Ωcm or less. The composition of the ink is mainly an organic solvent, resin and pigment mainly composed of 2-butanone and ethanol. Since these are low in conductivity, the resistance is as high as about 5000 to several tens of thousands of Ωcm when ink is formed only by this, and it becomes difficult to perform desired printing with a charge control type ink jet printer. It is preferable to use a complex as the conductive agent. The conductive agent must be dissolved in the solvent used, and it is also important that the color tone is not affected. In general, a conductive agent having a salt structure is used. It is presumed that this has high electrical conductivity because it has a charge bias in the molecule. A substance having a non-salt structure is not appropriate to be added to the ink of the present invention because the resistance does not become 2000 Ωcm or less unless added in a considerable proportion.

  As a result of examination from the above viewpoint, it was found that the conductive agent has a salt structure and the cation has a tetraalkylammonium ion structure. The alkyl chain may be linear or branched, and the greater the carbon number, the better the solubility in the solvent. However, the smaller the carbon number, the lower the resistance with a small addition rate. The realistic carbon number when used for ink is about 2 to 8.

  As the anion, hexafluorophosphate ion, tetrafluoroborate ion, and the like are preferable because of high solubility in a solvent.

  Although perchlorate ions are also highly soluble, they are explosive and are not practical to use in ink. In addition, chlorine, bromine and iodine ions may be mentioned, but these are not preferable since they tend to corrode when they come into contact with metals such as iron and stainless steel.

  From the above, preferred conductive agents are tetraethylammonium hexafluorophosphate, tetrapropylammonium hexafluorophosphate, tetrabutylammonium hexafluorophosphate, tetrapentylammonium hexafluorophosphate, tetrahexylammonium hexafluorophosphate, tetraoctylammonium. Hexafluorophosphate, tetraethylammonium tetrafluoroborate, tetrapropylammonium tetrafluoroborate, tetrabutylammonium tetrafluoroborate, tetrapentylammonium tetrafluoroborate, tetrahexylammonium tetrafluoroborate, tetraoctylammonium tetrafluoroborate, etc. .

  When using an ink containing a leuco dye, a developer, and a decolorizer, the type of decolorizer should be changed for the time from when the ink contained in the temperature indicator deviates from the set temperature range until the color changes. Can be adjusted.

  Note that the present invention is not limited to the charge control type ink jet printer. Therefore, the composition of the ink solution or the like is not limited to the above.

  Furthermore, instead of ink, it may be realized with a semiconductor element or the like. For example, a semiconductor element having a similar appearance can be configured by combining a temperature sensing portion, a plurality of display portions, and a control portion. The object to be sensed is not limited to temperature, but may be humidity, light, vibration, etc., or a combination of each. The present invention does not limit the method for realizing the part for sensing the environmental state and the part for displaying.

  In the second embodiment and below, only the differences from the first embodiment will be described. FIG. 5 is an environment history display object including an index 70 indicating the range of the management environment. The index 70 divides a plurality of marks from marks that change color when deviating from the management environment of the management history display item and other marks. The situation that leads to quality degradation can be grasped only by the environmental change mark, but it is difficult to judge the presence or absence of deviation. When such a division is made, if any of the marks in the upper right from this line is discolored, it means that the management environment has been deviated. It can be determined immediately.

  In the second embodiment, the environment history display object displaying a line as the index 70 is shown. However, the index indicating the range of the management environment can be changed by, for example, changing the color of the background, changing the size of the mark, or the mark before or after the color change. It may be expressed by a method such as changing the color.

  FIG. 6 shows an environment history display object expressing an index indicating the range of the management environment by changing the size of the mark. FIG. 7 shows an environment history display object expressing an index indicating the range of the management environment by expressing the environment change mark using characters, symbols, and the like.

  In the third embodiment, an environment history display object that allows a reader to mechanically deviate from the management environment will be described. FIG. 8 shows an environment history display object including a two-dimensional code 80 in addition to the display unit 21 having a plurality of environment change marks. The two-dimensional code 80 is provided in the vicinity of the display unit 21. In the two-dimensional code, character strings such as numerals and alphabets are expressed by patterns. In this embodiment, the character string includes data relating to the presence / absence, number, type, position, and the like of the environment change mark. However, the two-dimensional code 80 in FIG. 8 merely shows the existence of the two-dimensional code, and the pattern does not represent an actual character string according to the present embodiment. Details of the character string targeted in this embodiment will be described later. In FIG. 2, the code having information on the presence / absence, number, type, position, etc. of the environment change mark is a two-dimensional code, but a one-dimensional code such as a barcode can also be used. There are various standards depending on the difference in the code expression method, but the present invention does not depend on these standards. Various conversion processes are performed when patterning a character string, but the present invention does not depend on the processing method. When the code and the environment change mark are written together, it is preferable that the code and the mark are easily captured as an image at the time of data reading. For example, it is preferable that the code and the environment change mark are arranged in the vicinity. The shape of the environmental change mark is not particularly limited, such as a square, rectangle, circle, ellipse, and rounded rectangle.

  For the environmental history display object according to the second embodiment, a two-dimensional code may be used in combination. FIG. 9 includes a plurality of display units having a plurality of environment change marks, an index 70 indicating the range of the management environment, and a two-dimensional code 80. The environmental change mark or the like may be printed directly on the product, or may be printed on a sticker and pasted on the product. The character string represented by the code may be printed in the form of characters in the vicinity. The one-dimensional code and the two-dimensional code are usually expressed by symbolizing the product type, the production date, the production location, and the like. By using the environment change mark in combination, it becomes easier to read the environmental history after the manufacture with a reader, collect it as data, and use it for quality control. In this embodiment, an example is shown in which data relating to the presence / absence, number (number of columns, number of rows), type, position, and the like of environmental change marks is included in a character string represented by a two-dimensional code.

  The simplest method is a method in which the presence / absence, number, type, position, and the like of an environmental change mark are directly represented as a character string in addition to a code representing a product in the character string. For example, the character string is “012345789; DATE3, 4, 5, 6, 7, 8, TEMP10, 15, 20, 23, 26, 30, X1.1Y0W0.15H0.2”. “01234456789” is a code representing a product, and a commonly used code is used as it is. “DATE 3, 4, 5, 6, 7, 8” has 6 columns of environmental change marks, and each of them changes color when 3, 4, 5, 6, 7, 8 days have passed since the environment changed. Represents that. “TEMP10, 15, 20, 23, 26, 30” indicates that there are six rows of environmental change marks, which change at 10, 15, 20, 23, 26, and 30 ° C., respectively. “X1.2Y0.1” represents that the position of the upper left mark serving as a reference among the plurality of environment change marks is 1.2 in the horizontal direction and 0.1 in the vertical direction. Finally, “W0.15H0.2” indicates that the mark interval is 0.15 in the horizontal direction and 0.2 in the vertical direction. The position can be expressed by an actual length such as mm, but is preferably a relative position using the reference position of the two-dimensional code. In this example, assuming a coordinate system in which the upper left reference point of the two-dimensional code is the origin, the upper right reference point is 1 in the horizontal direction, and the lower left reference point is 1 in the vertical direction, the position and the mark interval are expressed. ing. When this method is used, the environment change mark can be read even if it is arranged at an arbitrary position and at an arbitrary scale. Details of the coordinates will be described in the fifth embodiment.

  In the above method, the character string displayed in the two-dimensional code portion becomes long, and the area necessary for displaying the two-dimensional code becomes wide. This problem can be solved by shortening the expression content. For example, “DATE3, 4, 5, 6, 7, 8” is changed to “D3-8”.

  If such a way of thinking is further advanced, a method of using the product code itself as a code representing the environmental change mark can be considered. For example, the first two characters of the product code represent the vertical and horizontal numbers of the environmental change mark, and the second character and the third character represent the number of days and the temperature. Since it is somewhat difficult to represent the position in the product code, it is also preferable to determine the standard position. That is, if there is no designation, such as a position, if there is a designation, the designated position. If this is all determined in advance as standard, it is not necessary to explicitly include data on the environmental change mark in the character string. That is, if a standard is defined for all products or for each product code, the number, position, and the like of the environmental change mark are determined simply by reading the product code.

  In the above example, the first part of the character string is only the product code, but a URL for accessing a specific site, for example, “http: //www.***.com/code.aspx? ID = 0123456789; DATE3 4, 5, 6, 7, 8, TEMP10, 15, 20, 23, 26, 30, X1.1Y0W0.15H0.2 ". How to display these displays is not limited in the present invention.

  Data relating to the position of the line that divides a mark that can be discriminated for the first time when it deviates from the management range and other marks may be added to the character string of the code. By using this data, it is easy to determine the deviation of the management range when the data is read.

  When a two-dimensional code is used in combination, the two-dimensional code printed on the product and the environmental change mark are read by the reader based on the operation of the person handling the product at the stage of manufacture, distribution, consumption, etc. Recorded or transmitted. Details of the reading method and the reading processing method will be described in a fifth embodiment. In general, a character string of a code is first read, and data related to a product code, the presence / absence of an environmental change mark, the number, type, position, and the like are extracted from the character string. Next, the color data of the environmental change mark is read based on the latter, and the product code and the color data are recorded and transmitted to the memory. Data transmitted from a plurality of readers is collected and recorded. From the recorded data, the corresponding data can be searched on the condition of the level of environmental change, a specific period, a specific location, a specific product code, a specific reader number and the like. The search results can be displayed in the form of a list, graph, map or the like. In the list, detailed measurement data can be referred to, and the aggregated value can be referred to as many as possible for each condition. Aggregated values can also be referenced in a graph. The environmental change value, period, place, product classification, number of data, etc. can be selected on the vertical axis. Moreover, if the data of the data reading location is used, it is possible to refer to the regional spread by plotting the number of points where the data of the specific condition is read at the corresponding location on the map. By referring to and analyzing these search results, it is possible to know the relationship between the environment where the product is placed and the deviation level, which can be used to improve the quality control method.

  In addition, if the color of the environment change mark has a characteristic that does not return to the original value once changed, it is possible to know a deviation state in the middle of reading a plurality of times. In addition, if data related to color determination is held in advance in the reading device, quality control quality can be determined at the time of reading without data transmission, and in such cases, a warning is displayed and a warning sound is generated. Can do. It is also possible to include a determination value in the character string represented by the code and perform determination using the value.

  In the fourth embodiment, as shown in FIG. 10, among a plurality of environment change marks (31a, 31b, 32c,...), A mark that changes color only when it deviates from the management range is distinguished from other marks. Only the marks near the index 70 are extracted and displayed. It can be seen that the environmental history display object on which only the extracted mark is displayed deviates from the management range in a state where one environmental change mark is discolored.

  FIGS. 11A to 11F are environment history display objects that display the extracted marks. It is not always necessary to arrange a plurality of marks in a line, and they may be arranged in a matrix as shown in FIGS. 11B and 11E, or as shown in FIGS. 11C and 11F. It may be arranged in an L shape. The present invention does not depend on these arrangement methods. Moreover, you may use a code | cord | chord together like Example 1. FIG.

  When it is desired to grasp only the presence or absence of deviation, the method of the fourth embodiment is preferable because the display area can be reduced. However, the method of the first embodiment is preferable when it is desired to grasp that the environment has deteriorated to the vicinity of the departure and the environment level after the departure. It can be used properly according to the purpose.

  FIG. 12 is a configuration diagram of the data reading processing apparatus 100 that reads the environment change mark of the environment history display object including the one-dimensional code or the two-dimensional code described in the third embodiment as data.

  The data reader 100 captures a one-dimensional code or two-dimensional code and an environment change mark, reads an image, an image input device 110, a storage device 130 that stores various data, an arithmetic device 120, and an input device 115. And an output device 120.

  The image input device 110 is a so-called camera that inputs an image, captures an image of a code portion and an environment change mark, and reads image data. The image data is recorded in the image data storage unit 131 in the storage device 130.

  The arithmetic device 140 processes the data input from the image input device 110 and the input device 115 and the data stored in the storage device 130, and outputs the result to the output device 120 or records the result in the storage device 130. It consists of the following processing units.

  The input control unit 141 is a part that performs processing of dividing data input from the image input device 110 or the input device 115 into commands, data, and the like, and transferring the data to each unit of the storage device or the arithmetic device. In particular, as main data, image data including a code and an environment change mark is transferred to the image data storage unit 131.

  The code position recognition unit 142 is a part that recognizes the code position from the image image data recorded in the image data storage unit 131 and records the recognition result in the code position data storage unit 132. Image data is usually composed of hundreds to thousands of dots both vertically and horizontally, and there is no data indicating which part is a code in the image itself. Therefore, the color data of each dot is analyzed to recognize which portion of the image data the code reference position corresponds to. The display form and number of reference positions differ depending on the code standards, but the present invention is not limited to these standards. The recognition result is preferably represented by a coordinate value such as the dot position of the image data, that is, the number from left to right and the number from top to bottom.

  The code recognizing unit 143 recognizes the character string data represented by the code from the image image data recorded in the image data storage unit 131 by using the position data recorded in the code position data storage unit 132. This is a part to be recorded in the code data storage unit 133.

  The environment change portion arrangement determination unit 144 determines the arrangement of the environment change mark using the code position data recorded in the code position data storage unit 132 and the character string data recorded in the code data storage unit 133. This is a part recorded in the environment change part arrangement data storage unit 134. The character string data recorded in the code data storage unit 133 includes information on the product code, the number, type, and position of the environment change mark, and the reading position is determined using these. The most preferable method is a method of calculating the position of the environment change mark using a coordinate system based on the reference position of the code. FIG. 13 shows an image of image data. A two-dimensional code 80 and an environmental change mark are recorded in a memory in which dots are arranged in a matrix of a vertical direction 1400 and a horizontal direction 1500. The three reference positions 81, 82, and 83 of the two-dimensional code are the dot positions of the image data, which are horizontal 100 and vertical 120, horizontal 900 and vertical 120, horizontal 100 and vertical 920, respectively. At this time, if the coordinates of the upper left mark 31a among the plurality of environment change marks are expressed as a horizontal direction 1.2 and a vertical direction 0.1 in the character string in the two-dimensional code, the horizontal direction of the environment change mark Can be calculated as (900−100) × 1.2 + 100 = 1060 and the vertical direction is (920−120) × 0.1 + 120 = 200. Also, assuming that the interval between marks is 0.15 in the horizontal direction and 0.2 in the vertical direction and is arranged in 6 columns and 6 rows in the vertical and horizontal directions, using these data, The position on the image data can be calculated. Here, for the sake of simplification, the case where the coordinates of the reference position of the code and the direction of the coordinates of the image data are the same has been described. However, if the directions are different, they can be converted by rotating them. Further, here, the example of only the center position of the environment change mark has been described, but it is possible to change the number of dots of the image to be read, the image range, and the like. In addition, although an example in which a plurality of marks are arranged in a matrix is described here, even if they are arranged randomly, the position of each mark is included by a method such as including in the character string recorded in the code. Can be decided.

  The color recognition unit 145 extracts the color data of the environment change mark from the image image data recorded in the image data storage unit 131 based on the arrangement data recorded in the environment change partial arrangement data storage unit 134, and the data Is recorded in the environmental change partial color data storage unit 135. As described above, if the arrangement data is expressed as the dot position of the image data, it can be processed simply by reading the dot data corresponding to the mark position. That is, it is a process of reading the color data of dots in the horizontal direction 1060 and the vertical direction 200. In order to remove noise data, it is also preferable that the size of the environment change mark is made larger than the dot interval, and data such as several points are read and averaged. Note that the color data can be processed in binary, such as black and white, but may be multi-tone or color having intermediate colors.

  The data recording unit 146 is a part that combines the character string data recorded in the code data storage unit 133 and the color data recorded in the environment change partial color data storage unit 135 and records them in the read data storage unit 136. is there. In general, in order to grasp the environmental change status of a product, it is desirable to have information on when, where and what happened. Therefore, it is preferable to record the date and time when the reading process is performed, the location, the reading device number, and the like in addition to the character string data and the color data. Note that the location and the number of the reading device do not change sequentially, so these may be assigned at the time of data output processing to be described later. Also, it is not necessary to include in the record parts that are not necessary for grasping the environment change situation, such as parts that represent the arrangement of the environment change mark. The location may be a pre-registered address or postal code, but it is preferable to record the measured longitude and latitude data using a reader with a GSP sensor.

  The output control unit 147 is a part that outputs the data recorded in the read data storage unit 136 to the output device 120. When the output destination is a screen or the like, it is preferable to output a result every time a reading operation is performed. At this time, it is preferable to determine whether the environmental condition is good or not from the color of the environmental change mark using the separately provided determination reference data, and output the result. When the output destination is a communication destination or the like, the output process may be performed each time a reading operation is performed, or may be processed by collecting several times of data, or at a predetermined time.

  Processing performed by the data reading processing apparatus 100 will be described. The data reader reads the one-dimensional code or the two-dimensional code, extracts information related to the arrangement of a plurality of marks from the information included in the read one-dimensional code or the two-dimensional code, and extracts the information related to the extracted arrangement of the plurality of marks. Based on this, information on the color change of the plurality of marks is read, and information on the color change of the plurality of marks is recorded.

  FIG. 14 shows a flow of processing performed by the data reading processing device 100. First, based on a command from the input control unit 141, image data including a code and an environment change mark is input from the image input device 110, and the data is recorded in the image data storage unit 131 (procedure 1201).

  Next, the image image data recorded in the image data storage unit 131 is transferred to the code position recognition unit 142, the reference position of the code is recognized, and the result is recorded in the code position data storage unit 132 (procedure 1202). ).

  Further, the image image data recorded in the image data storage unit 131 and the position data recorded in the code position data storage unit 132 are transferred to the code recognition unit 143, and character string data represented by the code based on the position data is transmitted. The result is recognized, and the result is recorded in the code data storage unit 133 (step 1203).

  Next, the presence / absence of an environmental change mark is determined from the character string data recorded in the code data storage unit 133, and only when there is, processing of the following procedure 1205 and procedure 1206 is performed (procedure 1204).

  When the environment change mark exists, the position data recorded in the code position data storage unit 132 and the character string data recorded in the code data storage unit 133 are first transferred to the environment change part arrangement determination unit 144, and the environment change mark Is determined, and recorded in the environment change partial arrangement data storage unit (134 (procedure 1205). The arrangement position determination method is as described above.

  Next, the arrangement data recorded in the environment change partial arrangement data storage unit 134 and the image image data recorded in the image data storage unit 131 are transferred to the color recognition unit 145, and the arrangement data in the image image are transferred. Is extracted, and the data is recorded in the environment change partial color data storage unit 135 (step 1206).

  The next processing is performed regardless of the presence or absence of the environment change mark. The character string data recorded in the code data storage unit 133 and the color data recorded in the environment change partial color data storage unit 135 are transferred to the data recording unit 146, and are combined and combined. Is recorded in the read data storage unit 136 (step 1207). In this compositing process, when there is no environmental change mark, in accordance with a predetermined format, combine the data indicating "None" or simply empty the data part of the environmental change mark color. It is processed as

  Finally, the data recorded in the read data storage unit 136 is transferred to the output control unit 147 and output to the output device 120 (procedure 1208).

  When the data is output, the image data recorded in the image data storage unit 131 becomes unnecessary, but it can be left as evidence or transmitted for recording in another device. Further, not all images may be recorded and transmitted, but may be recorded and transmitted only when they deviate from the management range.

  The apparatus according to the present embodiment is preferably a general-purpose smartphone having a camera, a screen, and a communication device, and executes a program that realizes the method described above. However, the present invention is not limited to this form.

  According to the data processing method, the following effects can be obtained. (1) It is possible to read the environmental change status of articles having different presence / absence, number, type, position, etc. of the environmental change mark with one type of reading device or reading method. (2) According to the product quality control method that records the read data and creates a database in a searchable form, it is possible to grasp the status of environmental changes during the transportation and storage of goods. (3) By using the above results, it is possible to find out where inappropriate management has been performed, and it is easy to improve the management method.

  As a simpler method than the present embodiment, the number and specifications of environment change marks are determined in advance, and if a reference mark that facilitates positioning is arranged in the vicinity of the environment change mark, a code is not used. Data can be collected only with the environmental change mark. A reference mark similar to that used in the two-dimensional code may be used as the reference mark, but is not limited thereto. Also, the reference mark may be formed by the environmental change mark itself.
