The first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram illustrating the configuration of a solid preparation printing machine according to Embodiment 1 of the present invention. FIG. 2 is a diagram illustrating a printing device portion of the solid preparation printing machine according to the first embodiment of the present invention. FIG. 3 is a diagram for explaining an example of printing defect in the first embodiment of the present invention.

As shown in FIG. 1, the solid preparation printer 100 according to the first embodiment of the present invention includes a disk 11, a disk 12, a disk 13, a parts feeder 14, a solid preparation input unit 15, a printing device 21, a printing device 31, and an imaging device. 41, an imaging device 51, a correction printing device 61, a correction printing device 71, a reprint sorting device 16, a storage box 17, a reprinting storage box 18, and the like. The disk 11 is provided with the main surface vertical, the disk 12 is provided vertically so as to be orthogonal to the disk 11 and the side surfaces are close to each other, and the disk 13 is horizontal so as to be orthogonal to the disk 12 and the side surfaces are close to each other. Is provided. The disk 11, the disk 12, and the disk 13 include a plurality of adsorption holes on the side surface circumference, and the solid preparation T can be adsorbed and held in the adsorption holes.

Next, the operation of the solid preparation printing machine 100 will be described. First, the solid preparation T is supplied to the parts feeder 14 from the solid preparation input unit 15. The solid preparation T thrown into the parts feeder 14 is gradually aligned in the horizontal direction by the vibration or rotation of the parts feeder 14. The aligned solid preparations T are adsorbed on the side surfaces of the plurality of adsorbing holes provided on the circumference of the side surface of the disk 13 at the final end of the parts feeder 14. The solid preparation T adsorbed and held in the adsorption holes on the side circumference of the disk 13 is horizontally rotated so as to approach the disk 12 as the disk 13 rotates counterclockwise. Then, the solid preparation T that has moved close to the disk 12 starts to be adsorbed to the adjacent adsorption holes in the disk 12, and the adsorption of the adsorption holes of the disk 13 is released, so that the first surface of the solid preparation T is Adsorb to adsorption holes. The disk 12 rotates in the vertical direction so that the solid preparation T adsorbed and held approaches the disk 11 by rotating clockwise. Then, the solid preparation T that has moved close to the disk 11 starts to be adsorbed to the adsorbing holes adjacent to the disk 11, and the adsorption of the adsorbing holes on the disk 12 is released so that the side surface of the solid preparation T is Adsorption is held in the adsorption hole. The solid preparation T adsorbed and held on the disk 11 is vertically rotated in the counterclockwise direction as the disk 11 rotates.

Next, the printing of characters and the like of the solid preparation T adsorbed on the disk 11, print inspection, and correction printing will be described in detail with reference to FIGS. The disk 11 is received by adsorbing the side surface of the solid preparation T in an upright position from the disk 12, and adsorbs and holds the solid preparation T in an upright position. When the disk 11 rotates counterclockwise, the solid preparation T adsorbed and held is rotated and moved counterclockwise. When the solid preparation T is rotated and moved to a position where the printing device 21 and the printing device 31 can print, the solid preparation T is detected by a sensor (not shown), and the printing device 21 prints characters or the like on the first surface of the solid preparation T. Then, characters or the like are printed on the second surface of the solid preparation T by the printing device 31. Both the printing device 21 and the printing device 31 are constituted by an inkjet printer, and the solid preparation T that is rotating and moving is ejected from a plurality of nozzles arranged in a line in a direction substantially orthogonal to the rotation direction of the disk 11. A predetermined character or the like can be printed on the screen. Characters and the like are stored in advance in a print data storage device (not shown), and a control device (not shown) appropriately instructs print data such as predetermined characters to control the printing device 21 and the printing device 31.

The nozzle rows in the printing device 21 and the printing device 31 are not limited to one row, and may have a plurality of nozzle rows. The printing device 21 and the printing device 31 are not limited to the ink jet printer, and may be a laser printer, a tampo printing device, or a screen printing device.

The printed solid preparation T is further rotated by the disk 11 further rotating counterclockwise. When the solid preparation T is rotated and moved to a position where the image pickup apparatus 41 and the image pickup apparatus 51 can pick up an image, the solid preparation T is detected by a sensor (not shown), and the image pickup apparatus 41 moves the first surface of the solid preparation T being rotated. The imaging device 51 images the second surface of the solid preparation T that is rotating and moving. The imaging device 41 and the imaging device 51 are both configured by CMOS sensors, and use an electronic shutter and a strobe to take an image so as not to shake the solid preparation T that is rotating and moving. The images picked up by the image pickup device 41 and the image pickup device 51 are sent to an inspection device (not shown) to inspect characters printed on each surface. At that time, the inspection apparatus receives the print data used for printing the characters of the solid preparation T from the control device, and compares the print data used for printing the solid preparation T with the print characters. To inspect. And an inspection apparatus specifies the defect content and defect location of the solid formulation T judged to be a printing defect.

That is, the print data used for printing the solid preparation T and the captured image such as the printed characters are overlapped and compared to determine whether there is any defect such as chipping, bleeding, or misalignment. That is, when there is a lack of printing in a part of the print character or the like, the content of the print defect is determined as a lack defect and a defective part is specified. In addition, when there is an extra print location in a portion other than the print data, the print failure is determined to be a bleeding failure and the bleeding failure location is specified. Further, when the position where the print character or the like should be printed is greatly deviated, it is determined that the print defect is a misalignment and the misalignment location is specified. In addition, when there are a plurality of defect contents, the defect contents and the defect locations for all the existing defect contents are specified.

In the first embodiment, a case where there is a chipping defect will be described in detail. FIG. 3A shows print data. As a result of printing based on this print data, it is assumed that an image such as a print character as shown in FIG. The inspection apparatus calculates the difference image by superimposing the captured image such as the print character and the image of the print data. FIG. 3C shows an example of the difference image. If the print character or the like is correctly printed by the print data, the difference image is controlled to display zero, that is, a white image. However, if there are different portions in the captured image such as the print character and the image of the print data, the different portion is displayed in black in the difference image. The number of pixels in the area displayed in black is counted, and if it is equal to or greater than a preset threshold value, it is determined as defective. If the black display portion equal to or greater than this threshold is within the area of the character to be printed, the defective content is determined to be defective. In addition, a black display area having the number of defective pixels, that is, the number of pixels equal to or greater than a threshold value is specified as a defective portion. However, an area composed of the number of pixels that are black but less than the threshold value is changed to white display. This is to prevent the inspection from becoming too strict. And the image which shows the defective part of the said black display area is memorize | stored in a control apparatus as a defective part image.

After the print inspection, the solid preparation T is rotated and moved to a position where the correction printing device 61 and the correction printing device 71 can print. However, the solid preparation T that has not been determined to be defective is further rotated without correction printing. And stored in the storage box 17.

The solid preparation T determined to be defective in printing is subjected to correction printing by the correction printing device 61 and the correction printing device 71. That is, when the solid preparation T is rotated and moved to a position where the correction printing apparatus 61 and the correction printing apparatus 71 can print, the solid preparation T is detected by a sensor (not shown), and the solid preparation T is determined to be defective in printing. If so, the correction printing device 61 performs correction printing on the first surface of the solid preparation T being rotated, and the correction printing device 71 performs correction printing on the second surface of the solid preparation T being rotated. Both the correction printing device 61 and the correction printing device 71 are constituted by an ink jet printer that can eject two different colors. Specifically, the modified printing device 61 and the modified printing device 71 are each configured by two inkjet printers, and are configured to be capable of selectively ejecting two types of ink, such as characters and the same color as the solid preparation T, respectively.

In Example 1, when the defective solid preparation T is rotated and transported, ink of a color or the like is ejected onto the solid preparation T only in the black display area of the defective portion image stored in the control device. Then refill the missing part with ink. As a result, ink is replenished to the chipped portion of the solid preparation T, the chipping disappears, and the solid preparation T can be relieved. The rescued solid preparation T is stored in the storage box 17 in the same manner as the solid preparation T that was not determined to be defective in printing.

In Example 1, the devices are arranged in the rotational movement direction of the solid preparation T, such as the printing device 21 and the printing device 31, the imaging device 41 and the imaging device 51, the modified printing device 61, and the modified printing device 71. The solid preparation T that has become defective in printing is remedied. However, the present invention is not necessarily limited to this, and can be appropriately changed depending on the convenience of the solid preparation printing machine. For example, the printing apparatus 21, the printing apparatus 31, the imaging apparatus 41, and the imaging apparatus 51 are provided, and after the defective solid preparation T is discharged, the solid preparation printing machine 100 is loaded again, and the printing apparatus 21 In addition, the printing apparatus 31 may be positioned as a correction printing apparatus so as to perform correction printing.

In Example 1, the printing device 21 and the printing device 31 print characters or the like on both surfaces of the solid preparation T, and the imaging device 41 and the imaging device 51 capture both surfaces of the solid formulation T to perform a print inspection. However, the present invention is not limited to this, and can be appropriately changed depending on the convenience of the solid preparation printing machine. For example, it may be configured such that characters or the like are printed on only one of the surfaces, and the printed inspection is performed only on the printed surface, so that correction printing is performed. Moreover, you may make it perform the external appearance inspection of the solid formulation T before printing. Furthermore, you may comprise so that the external appearance test | inspection may be carried out by imaging the side surface of the solid preparation T in which the 1st surface is adsorbed by the disk 12 with an imaging device.

In Example 1, since the solid preparation T adsorbed and held with the rotation of the disk 11 does not shift with respect to the disk T, the black portion of the defective portion image stored in the control device is displayed in the black display area. Based on this, the correction printing device 61 and the correction printing device 71 are configured to perform correction printing by discharging ink. Further, when the solid preparation T is transported by a drum or a magazine, the position is hardly shifted, so that correction printing can be performed with the same configuration. However, since the position may be shifted when the solid preparation T is conveyed by the conveyor, the position of the solid preparation T is recognized before the correction printing, and the position of the solid preparation T or the defective portion image is corrected. You may comprise so that correction printing may be performed.

As described above, the first embodiment of the present invention is a solid preparation printing method for printing characters or the like on the surface of a solid preparation, printing characters or the like with a printing apparatus, performing print inspection with an inspection apparatus and printing. A defective solid preparation is identified by a solid preparation printing method, wherein a defective content and a defective portion in a defective solid preparation are identified, and correction printing is performed on the defective portion with the correction printing apparatus according to the defective content. Even so, it can be remedied without wasting it.

Moreover, it is a solid preparation printing machine that prints characters on the surface of a solid preparation, a printing device that prints letters etc. on the solid preparation, and inspection of the printed characters etc. An inspection device that identifies the defective portion, a correction printing device that performs correction printing according to the content of the defect, and a control device that controls the printing device, the inspection device, and the correction printing device. With the solid preparation printing machine characterized in that, even a solid preparation with poor printing can be remedied without being wasted.

The second embodiment of the present invention is different from the first embodiment in that the printing defect content is a bleeding defect. Hereinafter, Example 2 will be described with reference to FIG. FIG. 4 is a diagram for explaining an example of a print blur defect in the second embodiment of the present invention. FIG. 4A shows print data, FIG. 4B shows an example of a picked-up image with poor bleeding, and FIG. 4C shows an example of a difference image between the print data and a defective blot image.

Operation | movement of the solid formulation printing machine 100 in Example 2 is demonstrated with reference to FIG. 1, FIG. Similar to the first embodiment, the disk 11 receives the side surface of the solid preparation T in the upright posture from the disk 12 and adsorbs and holds the solid preparation T in the upright posture. When the disk 11 rotates counterclockwise, the solid preparation T adsorbed and held is rotated and moved counterclockwise. When the solid preparation T is rotated and moved to a position where the printing apparatus 21 and the printing apparatus 31 can print, the solid preparation T is detected by a sensor (not shown), and the printing apparatus 21 causes the first surface of the solid preparation T being rotated to move. Characters and the like are printed, and the characters and the like are printed on the second surface of the solid preparation T that is being rotationally moved by the printing device 31. Both the printing device 21 and the printing device 31 are constituted by an ink jet printer, and by discharging ink from a plurality of nozzles arranged in a line in a direction substantially orthogonal to the rotation direction of the disk 11, a predetermined character or the like is formed into a solid preparation. Can be printed on T. Characters and the like are stored in advance in a print data storage device (not shown), and a control device (not shown) appropriately instructs print data such as predetermined characters to control the printing device 21 and the printing device 31.

The printed solid preparation T is continuously rotated as the disk 11 further rotates counterclockwise. When the solid preparation T is rotated and moved to a position where the image pickup apparatus 41 and the image pickup apparatus 51 can pick up an image, the solid preparation T is detected by a sensor (not shown), and the image pickup apparatus 41 moves the first surface of the solid preparation T being rotated. The imaging device 51 images the second surface of the solid preparation T that is rotating and moving. The imaging device 41 and the imaging device 51 are both configured by CMOS sensors, and use an electronic shutter and a strobe to take an image so as not to shake the solid preparation T that is rotating and moving. The images picked up by the image pickup device 41 and the image pickup device 51 are sent to an inspection device (not shown) to inspect characters printed on each surface. At that time, the inspection apparatus receives the print data used for printing the characters of the solid preparation T from the control device, and compares the print data used for printing the solid preparation T with the print characters. To inspect. And an inspection apparatus specifies the defect content and defect location of the solid formulation T judged to be a printing defect. In addition, the rotational movement is continued without doing anything for the solid preparation T that has not been determined to be defective in printing.

That is, the print data used for printing the solid preparation T is compared with the print characters and the like, and it is determined whether there is any defect such as chipping, bleeding or displacement. In the second embodiment, a case where there is a bleeding defect will be described. The inspection apparatus overlaps the captured image such as the print character and the image of the print data and calculates a difference image (see FIG. 4C). If the print character or the like is correctly printed by the print data, the difference image is controlled to display zero, that is, a white image. However, if there are different portions in the captured image such as the print character and the image of the print data, the different portion is displayed in black in the difference image. The number of pixels in the area displayed in black is counted, and if it is equal to or greater than a preset threshold value, it is determined as defective. If the black display portion equal to or greater than this threshold is outside the area of the printed character or the like, the defective content is determined to be blurred. In addition, a portion where the bleeding is defective, that is, a black display region having the number of pixels equal to or greater than the threshold is specified as a defective portion. However, an area composed of the number of pixels that are black but less than the threshold value is changed to white display. This is to ensure that the inspection is not too strict. And the image which shows the defective part of the said black display area is memorize | stored in a control apparatus as a defective part image.

Following the print inspection, the solid preparation T is rotationally moved to a position where the correction printing device 61 and the correction printing device 71 can print. If the solid preparation T is rotated and moved to a position where the correction printing apparatus 61 and the correction printing apparatus 71 can print, the solid preparation T is detected by a sensor (not shown), and the solid preparation T is determined to be defective in printing. For example, the correction printing device 61 performs correction printing on the first surface of the solid preparation T being rotated, and the correction printing device 71 performs correction printing on the second surface of the solid preparation T being rotated. Both the correction printing device 61 and the correction printing device 71 are constituted by an ink jet printer that can eject two different colors. Specifically, the modified printing device 61 and the modified printing device 71 are each configured by two inkjet printers, and are configured to be capable of selectively ejecting two types of ink, such as characters and the same color as the solid preparation T, respectively.

When the solid preparation T with poor bleeding is rotated and moved, the same color ink as that of the solid preparation T is ejected only in the black display area of the above-described defective portion image, and the ink is superimposed on the bleeding portion for correction printing. Controlled by the control device. Thereby, the bleeding part in the said solid formulation T becomes the same as the color of the solid formulation T, a blur disappears, and the said solid formulation T which was a printing defect can be relieved. The rescued solid preparation T is controlled by the control device so that the solid preparation T is stored in the storage box 17 in the same manner as the solid preparation T that has not been determined to be defective in printing.

When it is determined that the solid preparation T has a defect in addition to a bleeding defect, both the defect content and the defect location are specified. Then, the corrected printing device 61 and the corrected printing device 71 are controlled so that ink of the same color as the solid preparation T is ejected to the bleeding defect portion, and ink of characters or the like is ejected to the missing portion. Thereby, the bleeding defect and the chipping defect are relieved.

As described above, in Example 2, the defective content is specified as a bleeding defect and the defective portion is specified, and correction printing is performed by overlaying the same color ink as the solid preparation T on the bleeding portion, thereby blurring characters and the like. Even a printed solid preparation can be saved without being wasted. Also, stains that do not affect the quality can be remedied by performing the same correction printing.

The third embodiment of the present invention is different from the first and second embodiments in that the print defect content is misalignment. Hereinafter, Example 3 will be described with reference to FIG. FIG. 5 is a diagram for explaining an example of misalignment in the third embodiment of the present invention. FIG. 5A shows print data, FIG. 5B shows an example of a captured image with poor displacement, and FIG. 5C shows a difference image between the print data and the defective displacement image. Since this misalignment defect is a defect content in which the printed characters and the like are largely deviated from the positions to be originally printed, once the ink of the same color as the solid preparation T is corrected and printed on the misaligned portion and discharged, the solid preparation again Relief by putting it in the printing press and reprinting.

Operation | movement of the solid formulation printing machine 100 in Example 3 is demonstrated with reference to FIG. 1, FIG. Similar to the first embodiment, the disk 11 receives the side surface of the solid preparation T in the upright posture from the disk 12 and adsorbs and holds the solid preparation T in the upright posture. When the disk 11 rotates counterclockwise, the solid preparation T adsorbed and held is rotated and moved counterclockwise. When the solid preparation T is rotated to a position where the printing apparatus 21 and the printing apparatus 31 can print, the solid preparation T is detected by a sensor (not shown), and characters or the like are formed on the first surface of the rotating solid preparation T by the printing apparatus 21. Are printed on the second surface of the rotating solid preparation T by the printing device 31. Both the printing device 21 and the printing device 31 are constituted by an ink jet printer, and by discharging ink from a plurality of nozzles arranged in a line in a direction substantially orthogonal to the rotation direction of the disk 11, a predetermined character or the like is formed into a solid preparation. Can be printed on T. Characters and the like are stored in advance in a print data storage device (not shown), and a control device (not shown) appropriately instructs print data such as predetermined characters to control the printing device 21 and the printing device 31.

The printed solid preparation T is continuously rotated as the disk 11 further rotates counterclockwise. When the solid preparation T is rotated and moved to a position where the image pickup apparatus 41 and the image pickup apparatus 51 can pick up an image, the solid preparation T is detected by a sensor (not shown), and the image pickup apparatus 41 picks up the first surface of the rotating solid preparation T. Then, the imaging device 51 images the second surface of the rotating solid preparation T. The imaging device 41 and the imaging device 51 are both configured by CMOS sensors, and take an image using an electronic shutter and a strobe so as not to blur. The images picked up by the image pickup device 41 and the image pickup device 51 are sent to an inspection device (not shown) to inspect characters printed on each surface. At that time, the inspection device receives the print data used for printing the character of the solid preparation T from the control device, and compares the print data used for printing the solid preparation T with the print character, etc. Perform an inspection. And an inspection apparatus specifies the defect content and defect location of the solid formulation T judged to be a printing defect. For the solid preparation T that has not been determined to be poor printing, the rotational movement is continued without doing anything here.

That is, the print data used for printing the solid preparation T and the captured image such as the printed characters are overlapped and compared to determine whether there is any defect such as chipping, bleeding, or misalignment. In the third embodiment, a case where there is a misalignment will be described. The inspection apparatus calculates a difference image by superimposing the captured image such as the print character and the image of the print data and comparing them (see FIG. 5C). If the print character or the like is correctly printed by the print data, the difference image is controlled to display zero, that is, a white image. However, if there are different portions in the captured image such as the print character and the image of the print data, the different portion is displayed in black in the difference image. The number of pixels in the area displayed in black is counted, and if it is an area having a preset threshold value or more, it is determined as defective. If the black display area above the threshold is outside the area of the character to be printed and the size of the black display area approximates the size of the character to be printed, the defective content is misaligned. Judge. In addition, the black display area having the number of pixels that is equal to or larger than the threshold is specified as the defective portion. However, the area that is black but is less than the threshold is changed to white. This is to ensure that the inspection is not too strict. And the image which shows the defective part of the said black display area is memorize | stored in a control apparatus as a defective part image.

Following the print inspection, the solid preparation T is rotationally moved to a position where the correction printing device 61 and the correction printing device 71 can print. When the solid preparation T is rotated to a position where the correction printing device 61 and the correction printing device 71 can print, the correction printing device is detected if the solid preparation T is detected by a sensor (not shown) and determined to be defective. 61, correction printing is performed on the first surface of the rotating solid preparation T, and correction printing is performed on the second surface of the rotating solid preparation T by the correction printing apparatus 71. Both the correction printing device 61 and the correction printing device 71 are composed of two ink jet printers that can eject two different colors. Specifically, it is configured such that two types of ink of the same color of the character and the like and the same color of the solid preparation T can be selectively ejected.

When the misaligned solid preparation T is rotated and moved, the ink of the same color as that of the solid preparation T is ejected onto the solid preparation T based on the above-described defective portion image, and the ink is superimposed on the misaligned portion for correction printing. This can be performed by the control device controlling so that ink is ejected only to the black display portion of the defective portion image stored in the control device described above. As a result, the misaligned portion becomes the same as the color of the solid preparation T, so there is no misalignment, and the solid preparation T is relieved. That is, it is possible to return to the same initial state that is not printed. The control device controls the reprint sorting device 16 to store the solid formulation T that has returned to the initial state in the reprint storage box 18. The solid preparation T stored in the reprinting storage box 16 is input again into the solid preparation printing machine 100 at an arbitrary timing, and printing, inspection, and correction printing are performed as necessary. In FIG. 2, the description of the reprint sorting device 16 is omitted.

In Example 3, the solid preparation T with poor displacement is ejected with ink of the same color as the solid preparation T and overlaid on the misaligned portion for correction printing, and then stored in the reprint storage box 18. In this case, it is again put in the solid preparation printing machine 100 to perform printing, inspection, and correction printing as necessary. However, the present invention is not necessarily limited to this, and can be appropriately changed depending on the convenience of the solid preparation printing machine. . For example, another printing device may be disposed downstream of the corrected printing device 61 and the corrected printing device 71 in the rotational direction of the solid preparation to print characters or the like on the relieved solid preparation T.

If it is determined that there are a chipping defect and a bleeding defect in addition to the shift defect, the defect content and the defect location of all the defects are specified. Then, the correction printing device 61 and the correction printing device 71 are controlled so that ink of the same color as the solid preparation T is discharged to the misalignment defective portion and the poor bleeding portion, and ink of a color such as a character is discharged to the missing portion. . As a result, misalignment, bleeding failure, and chipping failure are remedied.

As described above, in Example 3, the defect content is specified as misalignment, the defect location is identified, and after the correction printing is performed by overlaying the same color ink as that of the solid preparation T on the misalignment portion, characters, etc. Can be relieved even if it is a solid preparation T printed with characters or the like shifted.
