BACKGROUND OF THE INVENTION
The present invention , Made of solid PTP packaging machine having a function of inspecting agent and Solid Has the function of testing agents Parcel Related to the machine.
[0002]
[Prior art]
Conventional tablets are printed with a manufacturer's symbol or a number or alphabet representing the type of tablet, and the symbol printed on the tablet is used to identify the varieties of bare tablets that are not stored in the packaging container. In addition to figures and numbers, specialists made appraisals based on experience based on shape and color. However, the appraisal work was very laborious. In addition, since numbers or alphabets are represented on small tablets, only three digits of information can be represented at most. Many types of tablets commercialized by thousands or tens of thousands of pharmaceutical companies, All could not be distinguished by this display. Therefore, there are many cases where identification is difficult even by expert evaluation. Also, it is difficult for humans to check these small numbers continuously in large quantities, while the numbers on these tablets are not for processing by an image processing device. It was also difficult to read by a processing device. Even if it was read, it was not enough to identify the model. Furthermore, since information such as the production time, lot, expiration date, and production location cannot be displayed, there was no reason to know when and where the tablets were made or whether they were within the expiration date. Therefore, it is impossible to confirm the expiration date of the tablet given to the patient in a hospital or the like. Further, even if an abnormality of a tablet is found in a subsequent process, such as a packaging process, it is not easy to specify the lot, making it difficult to deal with the abnormality.
[0003]
This means that every single dose taken at a pharmacy or hospital Parcel Do Parcel In the work, picking or Parcel It has also been very difficult to confirm whether the tablets supplied from the tablet supply unit of the machine (hereinafter referred to as “tablets that have been picked, etc.”) are correct. While it is impossible for a person to read a large number of various kinds of tablets while reading small characters printed on the tablets, it has also been considered to use an image processing device, but the orientation of picked tablets etc. is constant Therefore, it is very difficult for the image processing apparatus to read the alphabets and numbers written on the tablets, and the determination is made based on the color and shape. Therefore, tablets with similar colors and shapes could not be distinguished.
[0004]
Also, in the PTP packaging machine, mixing of different varieties is a serious defect that leads to wrong use, so it is required to inspect the mixing of different varieties in the packaging process or after packaging. Parcel Not only the orientation of the tablets is not fixed as in the case of the machine, but thousands of tablets are processed per minute, so it is impossible to inspect by human eyes, and the image processing apparatus also makes judgments based on color and shape Was only proposed. Therefore, tablets with similar colors and shapes could not be distinguished.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the solid preparation according to the first embodiment represents a two-dimensional code that is a code suitable for image processing representing at least a variety on the surface of a tablet 1 that is a solid preparation. Code suitable for image processing can be processed by binarization, and even if the scanning direction does not coincide with the X-axis or Y-axis of the code, the existence, position and range of the code can be easily known It is a code that can. For example, since characters such as Arabic numerals are recognized by pattern matching, if the X-axis, Y-axis, and size do not match completely, it cannot be recognized that they are numbers, so it is suitable for image processing. However, generally used barcodes are processed by the ratio of the white part to the black part even if the angle is slightly shifted, so for example by searching the data in the image memory from 3 to 5 directions The presence and range of the barcode can be confirmed. Although not shown in the figure, the same code is also shown on the opposite side of the tablet. In this embodiment, the tablet is white with a sugar coating, and has a cylindrical shape as shown in FIG. 1 which is a front view of the tablet 1 and FIG. 2 which is a side view. FIG. 3 shows a two-dimensional code represented almost at the center of the tablet. As proposed in Japanese Patent Laid-Open No. 10-214317, the two-dimensional code is a cell in which data represented by a binary code is arranged and arranged as a two-dimensional matrix pattern. And a control code area and a data area which are used for detecting the coordinates of the data cell and which indicate the size information or format information of the two-dimensional code. The two-dimensional code in this embodiment is printed with black ink, and is represented by black ink and white which is the background color of the tablet.
[0021]
As shown in FIG. 3, the positioning symbol 3 in the present embodiment is a figure formed by concentrically overlapping similar rectangles, and when the image is taken by a CCD camera, the light / dark component ratio of the scanning line crossing the center thereof Is dark: bright: dark: bright: dark = 1: 1: 3: 1: 1. This is the same ratio no matter what angle is scanned as long as the center is crossed. Therefore, whether or not there is a portion having a ratio of dark: bright: dark: bright: dark = 1: 1: 3: 1: 1 in the video signal for each line imaged by the CCD camera, The presence or absence of a 2D code can be determined, and no matter what direction the 2D code is installed, the 2D code can be quickly and easily just by scanning in a certain direction without processing the video signal between each line. It is possible to specify the presence or absence and the position thereof. In this embodiment, after specifying the positioning symbol 3, the positioning symbol 3 is arranged at the apex of the rectangular two-dimensional code so that it is easy to specify the range of the entire two-dimensional code.
[0022]
The control code area of the two-dimensional code in this embodiment is composed of timing cells 4 and 5 and format information 6, and the timing cells 4 and 5 have the positioning symbol 3 of the two-dimensional code as a vertex as shown in FIG. On two sides, black, white, black, black cells, and white cells are arranged alternately from the position separated by one cell from the positioning symbol 3, and detection of the coordinates of the data cell or two-dimensional code It is used to detect the size of The format information 6 is arranged along the positioning symbol 3 at a position separated by one cell from the positioning symbol 3 as shown in FIG. In the data area 7, data is arranged according to the format information 6 in an inverted L-shaped area between the timing cell 4 and the timing cell 5. The data represented in the data area 7 represents product type information, information such as date of manufacture, lot or expiration date, or combination information thereof.
[0023]
In this embodiment, since the tablets that are solid preparations are provided with a code suitable for image processing representing at least the product type, the product type of the tablet can be easily known using an image processing apparatus, for example, a packaging process or In a hospital or pharmacy Parcel In the process, it is possible to easily inspect whether there is an error in the product type using an image processing apparatus. In addition, by including the date of manufacture or the expiration date in the code, it is possible to confirm whether or not an old tablet is mixed in the packaging process, and the reliability of the expiration date printed on the package later increases. Moreover, even if it is a naked tablet taken out from the packaging container, the expiration date can be confirmed.
[0024]
In addition, by including a lot number in the code, even when an abnormal tablet is found later, the lot can be easily identified, and handling of the abnormality can be facilitated. Further, since the code is a two-dimensional code in which data represented by a binary code is converted into a cell and arranged as a two-dimensional matrix pattern, a large amount of information can be expressed without difficulty even in a small tablet. . Accordingly, many types can be easily distinguished, and information other than the types, for example, information such as date of manufacture, lot, and expiration date can be expressed. Further, since the two-dimensional code has a positioning symbol that can obtain the same frequency component in a scanning line that crosses the center at any angle, the position of the two-dimensional code can be easily specified in the image processing apparatus. it can. Therefore, packaged tablets on PTP packaging machines, Parcel By machine Parcel The two-dimensional code attached to the tablet can be easily specified even in a state where the orientation of the tablet is not fixed as in the case of the prepared tablet.
[0025]
In addition, since the positioning symbol is provided at the apex of the two-dimensional code, it is easy to specify the range of the two-dimensional code. Further, since the positioning symbol is arranged only at one position of the vertex of the two-dimensional code and is a rectangular two-dimensional code as a whole, the position can be easily identified and a large amount of information can be expressed in a small area. Further, since the code is located at the approximate center of the tablet, the position of the code can be specified from the shape of the tablet, and the processing is accelerated. In addition, a lens lock or the like can obtain an image with relatively little distortion when imaged from above, and the processing by the image processing apparatus becomes easy.
[0026]
In addition, since codes are provided on both sides of the tablet, for example, even after tablets are PTP-wrapped with a light-impervious lid film, images of the tablets are always inspected by imaging from the transparent container film side. can do. Moreover, since the tablet is a sugar-coated tablet, the surface of the tablet can be smoothed, so that a fine code can be displayed. In addition, since the color of the code attached to the tablet is black and the color of the tablet is white, even if the surface of the tablet such as a lens tablet is not a simple flat surface, even if the image processing apparatus does not perform shading correction, it is binary. It is easy to read the code.
[0027]
The present invention is not limited to this example, and the solid preparation may be a capsule as long as it can represent a code. The tablet is not limited to a cylindrical shape, and may be a lens shape. Moreover, the color of the code | symbol attached | subjected to the tablet and the tablet may be other colors as long as the code can be read with the tablet as a background.
[0028]
The tablet is not limited to a sugar-coated tablet, and may be a plain tablet or the like if the code can be expressed by printing or the like. In addition, the code is not limited to printing. The code is expressed not only by printing, but by expressing the color of the lower layer on the surface by, for example, destroying the surface of the tablet with a two-layer structure with different colors with a laser or the like. Alternatively, a layer that is discolored by a laser may be provided on the surface of the tablet, and the layer may be discolored by irradiation with a laser. The code attached to the tablet may be a decodable code that can easily specify the position, orientation, range, and size of the code by the image processing apparatus, that is, a code suitable for image processing. As shown in FIG. 5, it may be a one-dimensional code generally called a barcode. However, in the case of a barcode, information that can be displayed in the same area is less than that of a two-dimensional code.
[0029]
Also, the two-dimensional code can be easily specified by the image processing apparatus, and the code position, orientation, range, and size can be specified. It may be. For example, as shown in FIG. 6, if the two-dimensional code is rectangular as a whole and positioning symbols are provided at the three vertices, the three vertices are identified from the positioning symbols, thereby obtaining the two-dimensional code. This range can be easily specified. Further, there is no need to separately provide a code representing the size of the two-dimensional code.
[0030]
Next, a tablet inspection apparatus for inspecting the solid preparation or the code attached to the tablet described above will be described below with reference to the drawings. As shown in FIG. 7, the tablet inspection apparatus in the present embodiment includes an illumination 16 that irradiates a tablet 1 that is a solid preparation, an imaging device 10 that images the tablet 1, and an image that processes a video signal output from the imaging device 10. The processing apparatus 11 is comprised.
[0031]
The tablet 1 is affixed with information such as the type and, if necessary, the date of manufacture, production lot or expiration date. In the present embodiment, as shown in FIG. 1, a case where a code is attached to the surface of the tablet 1 in the form of a two-dimensional code will be described below. The two-dimensional code has a rectangular shape and has one positioning symbol at one location of the vertex of the two-dimensional code.
[0032]
The image processing device 11 receives a video signal from the imaging device 10 and decodes the code including the tablet type information displayed on the tablet 1. The product type setting sets and stores the information of the tablet type that should be originally stored. The means 14, the kind information of the kind setting means 14 and the kind information of the tablet 1 outputted from the decoding means 12 are compared to judge whether or not the kind is correct, and the kind information is outputted from the decoding means 12. The display unit 17 for displaying the decoded data, the determination result output from the different product type determination unit 13 or the setting content of the product type setting unit 14, and the output unit 15 for outputting to the outside as necessary.
[0033]
The decoding procedure of the decoding means 12 will be described with reference to the flowchart of FIG. First, in step 1 (hereinafter referred to as S1), a video signal obtained by imaging a tablet input from the image processing apparatus 10 is binarized.
[0034]
Next, in S2, a two-dimensional code is specified. The two-dimensional code is specified by specifying a positioning symbol. In the case of the two-dimensional code of this embodiment, as shown in FIG. 4, a constant frequency component (dark: bright: dark: bright: dark = 1: 1: 3) can be scanned from any angle as long as the center of the symbol passes. : 1: 1), a positioning symbol is generated. Therefore, a positioning symbol can be easily specified by searching for its frequency component in the direction along the scanning row, for example. If the positioning symbol can be specified, the two-dimensional code can be easily specified because the rectangle having two sides consisting of the positioning symbol and the timing cell is the two-dimensional code.
[0035]
If the two-dimensional code can be specified, next, in S3, the two-dimensional code is decoded. In the decoding of the two-dimensional code, first, the coordinate of the two-dimensional code is converted so that the two points of the timing cell are parallel to the X axis or the Y axis with the point where the positioning symbol is the vertex of the two-dimensional code as the origin. Then, 1 and 0 of each cell arranged in a matrix are specified according to the timing cell. Next, the format information is read from the cell representing the format information, and the information of each cell is read according to the format information. The information decoded in this manner includes information such as the type of tablet and the date of manufacture, lot, and expiration date if necessary.
[0036]
The operation of the tablet inspection apparatus shown in the present embodiment will be described below. First, the tablet 1 to be inspected is prepared at the imaging position of the imaging device 10. One or more tablets may be imaged at a time. Also, a plurality of the same type of tablets may be used, and a plurality of different types of tablets may be used. The video signal of the tablet 1 output from the imaging device 10 is sent to the decoding means 12 of the image processing device 11 as a multi-value signal. The decoding means 12 identifies and decodes the two-dimensional code attached to the tablet 1. On the other hand, the kind setting means 14 stores the kind or kind of tablets that should be originally present and the number thereof. The different kind discriminating means 13 compares the data of the kind or kind of the tablet 1 and the number thereof output from the decoding means 12 with the data of the kind or kind and the number outputted from the kind setting means 14 so as to match. If it matches, the fact that it is correct is displayed, and if it does not match, it is displayed on the display means 17 which tablet is wrong and how many tablets, and the output means 15 outputs it.
[0037]
In this embodiment, since the image processing apparatus includes a decoding unit that decodes the code attached to the tablet, necessary information attached to the tablet can be recognized. For example, it is possible to accurately specify various complex varieties. Further, since the code attached to the tablet is a two-dimensional code, and the decoding means decodes the two-dimensional code, a large amount of information can be read accurately and stably even in a small tablet. Therefore, for example, many varieties can be easily distinguished, and information other than the varieties, for example, information such as date of manufacture, lot, and expiration date can be expressed on the tablet and can be read.
[0038]
Further, since the two-dimensional code has a positioning symbol that can obtain the same frequency component in a scanning line that crosses the center at any angle, the position of the two-dimensional code can be easily specified in the image processing apparatus. it can. Therefore, packaged tablets on PTP packaging machines, Parcel By machine Parcel The two-dimensional code attached to the tablet can be easily specified even in a state where the orientation of the tablet is not fixed as in the case of the prepared tablet.
[0039]
In addition, since the positioning symbol is provided at the apex of the two-dimensional code, it is easy to specify the range of the two-dimensional code. Further, since the positioning symbol is arranged only at one position of the vertex of the two-dimensional code and is a rectangular two-dimensional code as a whole, the position can be easily identified and a large amount of information can be expressed in a small area.
[0040]
In addition, since the code attached to the tablet includes at least information for identifying the type of the tablet, and the decoding means decodes at least the type of the tablet, it is possible to accurately and reliably distinguish many types. Further, since the image processing apparatus has a different kind discriminating means for discriminating whether or not the kind of the tablet decoded by the decoding means is a different kind, for example, a tablet of a kind different from the designated kind is erroneously detected. Even if it is, it can be easily understood and accidents caused by accidentally taking tablets of different varieties can be prevented.
[0041]
The present invention is not limited to this example, and the tablet may be a solid preparation such as a capsule as long as it can represent a code. The code attached to the tablet is a decodable code that can easily identify the position and range of the code by the image processing apparatus, that is, a code suitable for image processing, for example, as shown in FIG. A one-dimensional code generally called a bar code may be used. Also, the two-dimensional code can be easily specified by the image processing apparatus, and the code position, orientation, range, and size can be specified. It may be. For example, as shown in FIG. 6, if the two-dimensional code is rectangular as a whole and positioning symbols are provided at the three vertices, the three vertices are identified from the positioning symbols, thereby obtaining the two-dimensional code. This range can be easily specified. Further, there is no need to separately provide a code representing the size of the two-dimensional code.
[0042]
In addition, the image processing apparatus 11 is provided with a manufacturing date discriminating unit, which captures a code including the manufacturing date attached to the tablet 1 and decodes it by the decoding unit 12, and a manufacturing date setting unit. By comparing the production dates set to, it is possible to remove tablets that are different from the production dates. For example, if this inspection apparatus is provided in the packaging process, products with different production dates or extremely old products will not be mixed in one packaging container. In addition, the image processing apparatus 11 is provided with an expiration date determining unit, and the expiration date attached to the tablet 1 is picked up, and the expiration date decoded by the decoding unit 12 is compared with the expiration date set in the expiration date setting unit. As a result, it is possible to remove a tablet that is about to expire. For example, pharmacies Parcel If this inspection apparatus is provided in the process, it is possible to remove tablets that are about to expire.
[0043]
The two-dimensional code may be specified by searching for the tablet after specifying the tablet. In particular, if a code is provided including the center of the tablet, the code can be easily detected by obtaining the center of the tablet. In addition, if the code is provided with the center of the code and the center of the tablet, or the center of the tablet and one vertex of the code are provided, the center or the vertex of the code is obtained by obtaining the center of the tablet. Can do. Also, by displaying the decoded product information directly on the display means 17 or by outputting it from the output means 15, for example, it is possible to identify the kind of the bare tablet not stored in the packaging container or to check the expiration date. You can also do it.
[0044]
Next, a PTP packaging machine according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 9, the PTP packaging machine in the present embodiment is equipped with the above-described tablet inspection apparatus in the PTP packaging machine 30, thereby providing a solid preparation with the code described above in the PTP packaging machine 30. For example, tablet inspection is performed.
[0045]
First, the PTP packaging machine 30 that performs tablet inspection will be briefly described. The PTP packaging machine 30 automatically wraps a solid preparation (tablet in this embodiment) on a PTP sheet. Specifically, first, a container film 40 such as polypropylene or PVC is fed into a heating plate 50 and a molding plate 51 with a film feed roll 33 and tension rolls 31 and 32, and a pocket filled with the tablet 1 is formed into a container film. . When the container film 40 having the pockets 41 is sent to the bottom of the tablet insertion shutter 52, the tablet insertion shutter 52 automatically fills the pockets with the tablets 1.
[0046]
Furthermore, the lid film 42 made of aluminum is fed through the tension rolls 34 and 35 onto the container film 41 in which the tablets 1 are filled in the respective pockets, and fixed by the pair of seal rolls 36. Thus, a film-like PTP sheet 43 in which the tablet 1 is filled in each pocket is manufactured. The film-like PTP sheet 43 is cut into a sheet shape, and then sequentially sent to a defective sheet discharge mechanism, a PTP sheet stacking mechanism, and the like (not shown).
[0047]
At the position of the fixed roll 37, the image of the tablet 1 filled in the pocket of the container film 41 and sealed by the lid film 42 is imaged through the container film 41 by the imaging device 10a constituting the above-described tablet inspection device. Similarly, the video signal is sent to the image processing device 11 constituting the tablet inspection device, and the code attached to the tablet 1 is decoded and whether or not the product set by the product setting means 14 matches the product type is determined. In FIG. 2, the tablet is discriminated for each tablet, and the tablet sheet containing the different varieties and the tablet sheet not containing the tablets are discharged in the later defective discharge mechanism.
