Description

  TECHNICAL FIELD The present invention relates to a quality confirmation system for confirming the quality of tablets contained in a blister sheet, and a blister packaging system including the system and a blister packaging machine.

  A blister sheet such as a PTP sheet is known which is composed of a container film having a pocket portion for accommodating tablets and a cover film attached to the container film so as to seal the opening side of the pocket portion. There is.

  The blister sheet is a pocket portion forming means for forming a pocket portion on a strip-shaped container film, a filling means for filling a tablet in the pocket portion, an attaching means for attaching a cover film to the container film, and a cover for the container film. It can be manufactured by a blister packaging machine having a separating means for separating a strip-shaped blister film to which a film is attached to obtain a blister sheet.

  Further, in the manufacturing process of the blister sheet, various inspection devices are provided along the transport path of the container film. The inspection device is manufactured by inspecting a portion that will finally become a blister sheet, for example, by performing an inspection regarding damage to tablets, inclusion of foreign matter in a pocket portion, a sealing state of a cover film with a container film, and the like. Determine the quality of the blister sheet. The blister sheet determined to be defective (defective sheet) is discharged by a predetermined discharging unit and stored in a hopper for defective products.

  By the way, a defective tablet may be contained in the discharged defective sheet. If such a defective sheet containing a non-defective tablet is discarded as it is, the non-defective tablet may be wasted, resulting in an increase in production cost. Therefore, there is a case where a non-defective tablet is taken out from the defective sheet and collected. The tablets are taken out and collected manually, for example. Further, in order to confirm whether or not the inspection by the inspection device is normally performed, the operator visually identifies the defect content in the tablet of the defective sheet, and the identified defect content and the inspection. In some cases, the result of the device determination may be compared with the quality determination result.

  Here, in order to perform various operations on tablets, such as taking out and collecting non-defective tablets and comparing the content of defects identified by visual inspection with the quality determination result by the inspection device, It is necessary to know individually whether each tablet contained in the sheet is good or bad. Conventionally, as a device for knowing whether each tablet is good or bad, the defective sheets are stacked and stored in a predetermined storage device, and when the defective sheets are taken out from the storage device, the defective sheets taken out by the predetermined display device are taken out. There has been proposed a device for displaying the quality judgment result of each tablet (see, for example, Patent Document 1). Further, there is also a device for displaying a pass / fail judgment result for each tablet of the defective sheet being conveyed by the conveying device in a state in which the conveying device for conveying the defective sheet is covered with a cover capable of displaying information. It is known (see, for example, Patent Document 2). According to these devices, the quality of each tablet on the defective sheet can be known relatively easily.

JP, 2008-21759, A JP, 2017-1698, A

  However, in both of the above-mentioned devices, after the defective sheet is taken out from the storage device or the cover, it is not possible to know the pass / fail judgment result from the taken-out defective sheet itself. Therefore, it is necessary to perform various operations for tablets while checking the displayed quality determination result, which may take time and effort. Further, when the position for displaying the quality determination result and the position for performing the work are separated from each other, it becomes impossible to perform the work while checking the quality determination result. Further, since the blister sheet is usually bilaterally symmetrical, depending on the orientation of the defective sheet at hand, it is not possible to accurately grasp the correspondence between the tablet of the defective sheet and the quality judgment result displayed. This may result in trouble in the work.

  The present invention has been made in view of the above circumstances, and an object thereof is to more easily confirm the quality of tablets contained in a blister sheet, and to more accurately grasp the quality of tablets. It is to provide a quality confirmation system and the like that can

  Hereinafter, an embodiment will be described with reference to the drawings. First, the structure of a PTP sheet as a blister sheet will be described in detail.

  As shown in FIGS. 1 and 2, the PTP sheet 1 has a container film 3 having a plurality of pockets 2 and a cover film 4 attached to the container film 3 so as to close the pockets 2. ing.

  The container film 3 in the present embodiment is formed of a transparent thermoplastic resin material such as PP (polypropylene) or PVC (polyvinyl chloride). On the other hand, the cover film 4 is made of an opaque material (for example, an aluminum foil) provided with a sealant made of polypropylene resin or the like on its surface. Of course, the materials for the films 3 and 4 are not limited to these, and other materials may be used.

  The PTP sheet 1 is manufactured by punching a strip-shaped PTP film 6 (see FIG. 4) formed from the strip-shaped container film 3 and the strip-shaped cover film 4 into a sheet shape, and has a substantially rectangular shape in a plan view. It is formed in a shape. On the PTP sheet 1, two pocket rows, each of which is composed of five pocket portions 2 arranged along the longitudinal direction, are formed in the lateral direction. That is, a total of 10 pocket portions 2 are formed. One tablet 5 is stored in each pocket 2. The tablet 5 can be visually recognized from the outside through the pocket 2 from the protruding side of the pocket 2 (see FIG. 3. Note that the tablet 5 is not shown in FIG. 1). In this embodiment, the PTP film 6 corresponds to a blister film.

  Further, as shown in FIGS. 1 and 3, an identification tag is provided on the surface of the cover film 4 that is attached to the container film 3 and corresponding to the vicinity of the edge of the PTP sheet 1. Information 7 is attached. The identification tag information 7 is visible through the container film 3. The identification tag information 7 is different for each PTP sheet 1 and is used to identify the PTP sheet 1. In the example shown in FIGS. 1 and 3, the identification tag information 7 is composed of a predetermined character (for example, the character “ABC”) and a predetermined number (for example, the number “123” in FIGS. 1 and 3). ing. In the present embodiment, the predetermined character is commonly attached to each PTP sheet 1, and the predetermined number is incremented by one in the order of manufacturing the PTP sheet 1. Note that the identification tag information 7 may be any information that enables the PTP sheet 1 to be identified, and may be information other than letters and numbers (for example, a barcode). The identification tag information 7 can be printed and formed by, for example, an inkjet printing machine, an offset printing machine, a letterpress printing machine, a flexographic printing machine, or the like.

  Next, referring to FIG. 5, a blister including a PTP packaging machine 10 for manufacturing the PTP sheet 1 and a quality confirmation system 60 for confirming the quality of the tablets 5 in the manufactured PTP sheet 1. The configuration of the packaging system 100 will be described. In this embodiment, the PTP packaging machine 10 corresponds to a blister packaging machine. First, the schematic configuration of the PTP packaging machine 10 will be described.

  As shown in FIG. 5, on the most upstream side of the PTP wrapping machine 10, the band-shaped container film 3 is wound in a roll shape. The withdrawal end side of the container film 3 wound in a roll shape is guided by the guide roll 13. The container film 3 is mounted on the intermittent feed roll 14 on the downstream side of the guide roll 13. The intermittent feed roll 14 is connected to a motor that rotates intermittently, and conveys the container film 3 intermittently.

  A heating device 15 and a pocket portion forming device 16 are sequentially arranged between the guide roll 13 and the intermittent feed roll 14 along the transport path of the container film 3. Then, when the container film 3 is heated by the heating device 15 and the container film 3 is relatively flexible, the pocket part forming device 16 forms a plurality of pocket parts 2 at predetermined positions on the container film 3. The pocket portion 2 is formed during the interval between the transport operations of the container film 3 by the intermittent feed roll 14.

  The container film 3 delivered from the intermittent feed roll 14 is loaded on a tension roll 18, a guide roll 19 and a film receiving roll 20 in this order. The film receiving roll 20 is connected to a motor that rotates at a constant speed, and therefore conveys the container film 3 continuously and at a constant speed. The tension roll 18 is in a state of being pulled to the side where the container film 3 is tensioned by the elastic force, and prevents the slack of the container film 3 due to the difference in the transport operation between the intermittent feed roll 14 and the film receiving roll 20. The film 3 is always kept in tension.

  A tablet filling device 21, a first inspection device 22, and a second inspection device 23 are sequentially arranged between the guide roll 19 and the film receiving roll 20 along the transport path of the container film 3.

  The tablet filling device 21 has a function as a filling unit that automatically fills the pocket 2 with the tablets 5. The tablet filling device 21 drops the tablets 5 by opening the shutter at predetermined intervals in synchronization with the operation of transporting the container film 3 by the film receiving roll 20, and each pocket portion in association with this shutter opening operation. 2 is filled with tablets 5.

  The first inspection device 22 and the second inspection device 23 determine whether or not there is an abnormality in the inspection target by using a portion such as the tablet 5 or the container film 3 (sheet portion) that finally becomes the PTP sheet 1 as the inspection target. A more detailed structure of the inspection devices 22 and 23 will be described later.

  On the other hand, the original fabric of the cover film 4 formed in a strip shape is wound in a roll shape on the most upstream side. Identification tag information 7 is attached to the cover film 4 in advance at regular intervals. The pull-out end of the cover film 4 wound in a roll shape is guided toward the heating roll 25 by the guide roll 24.

  The heating roll 25 can be pressed against the film receiving roll 20, and the container film 3 and the cover film 4 are fed between the rolls 20 and 25. Then, the container film 3 and the cover film 4 pass between the rolls 20 and 25 in a heat-pressed state, so that the cover film 4 is attached to the container film 3 and the pocket 2 is closed by the cover film 4. . As a result, the strip-shaped PTP film 6 in which the tablets 5 are housed in the pockets 2 is manufactured. In the present embodiment, the film receiving roll 20 and the heating roll 25 constitute an attaching means.

  It should be noted that the cover film 4 and the container film 3 are aligned by a not-shown alignment means or the like, so that when the cover film 4 is attached to the container film 3, it corresponds to the vicinity of the edge of the PTP sheet 1. The identification tag information 7 is provided at an appropriate position.

  The PTP film 6 delivered from the film receiving roll 20 is loaded on the tension roll 27 and the intermittent feed roll 28 in this order. Since the intermittent feed roll 28 is connected to the motor that rotates intermittently, the PTP film 6 is intermittently transported. The tension roll 27 is in a state of being pulled to the side where the PTP film 6 is tensioned by the elastic force, and prevents the PTP film 6 from loosening due to a difference in transport operation between the film receiving roll 20 and the intermittent feed roll 28. The PTP film 6 is always kept in a tensioned state.

  A third inspection device 26 is provided between the film receiving roll 20 and the tension roll 27 along the transport path of the PTP film 6. The third inspection device 26 determines whether or not there is an abnormality in the inspection target by using a portion such as the tablet 5 or the PTP film 6 (sheet portion) that finally becomes the PTP sheet 1 as the inspection target. The more detailed structure of the third inspection device 26 will be described later.

  The PTP film 6 delivered from the intermittent feed roll 28 is loaded on the tension roll 31 and the intermittent feed roll 32 in this order. Since the intermittent feed roll 32 is connected to the motor that rotates intermittently, the PTP film 6 is intermittently transported. The tension roll 31 is in a state of being pulled to the side where the PTP film 6 is tensioned by the elastic force, and prevents the PTP film 6 from loosening between the intermittent feed rolls 28 and 32.

  A slit forming device 33 and a marking device 34 are sequentially arranged between the intermittent feed roll 28 and the tension roll 31 along the transport path of the PTP film 6. The slit forming device 33 has a function of forming a slit for separation at a predetermined position of the PTP film 6. Further, the marking device 34 has a function of marking at a predetermined position on the PTP film 6 (for example, a position avoiding the identification tag information 7). Note that, in FIG. 1 and the like, the illustration of the slits for separation and the markings is omitted.

  The PTP film 6 delivered from the intermittent feed roll 32 is wound on the downstream side of the tension roll 35 and the continuous feed roll 36 in this order. A sheet punching device 37 is arranged between the intermittent feed roll 32 and the tension roll 35 along the conveyance path of the PTP film 6. The sheet punching device 37 has a function of punching the outer edge of the PTP film 6 in units of PTP sheets. The sheet punching device 37 constitutes the separating means in this embodiment.

  The PTP sheet 1 obtained by punching the PTP film 6 by the sheet punching device 37 is conveyed by the conveyor 39 and is temporarily stored in the finished product hopper 40. However, the PTP sheet 1 determined to be a defective product by at least one of the inspection devices 22, 23, and 26 is not sent to the finished product hopper 40, but is separately discharged by the defective sheet discharge mechanism 45, and It is stored in the good quality hopper 44. The operator can take out the defective PTP sheet 1 from the defective hopper 44.

  A cutting device 41 is disposed downstream of the continuous feed roll 36. Then, the unnecessary film portion 42 forming the residual material portion (scrap portion) remaining in a strip shape after punching by the sheet punching device 37 is guided to the tension roll 35 and the continuous feed roll 36, and then guided to the cutting device 41. . The continuous feed roll 36 is in pressure contact with the driven roll, and carries out the conveying operation while sandwiching the unnecessary film portion 42. The cutting device 41 cuts the unnecessary film portion 42 into a predetermined size. The unnecessary film portion 42 (scrap) that has been cut is stored in the scrap hopper 43 and then separately discarded.

  The rolls 14, 20, 28, 31, 32 and the like have a positional relationship in which the roll surface and the pocket portion 2 face each other, but the pocket portion 2 is provided on the surface of the intermittent feed roll 14 or the like. Since the concave portion to be accommodated is formed, the pocket portion 2 does not collapse. Further, the feeding operation is performed while the pocket portion 2 is accommodated in each concave portion such as the intermittent feeding roll 14, so that the intermittent feeding operation and the continuous feeding operation are reliably performed.

  Next, a more specific configuration of the inspection devices 22, 23 and 26 will be described with reference to FIG. Each of the inspection devices 22, 23, and 26 includes an illumination device 50, an inspection camera 51 as an inspection image pickup unit, and a pass / fail determination device 52 as a pass / fail determination unit.

  The illuminating device 50 uses a predetermined light (for example, near-infrared light) from the opening side or the protruding side of the pocket portion 2 to a portion (inspection target) that finally becomes the PTP sheet 1, such as the container film 3 and the PTP film 6. Light or visible light).

  The inspection camera 51 images the light emitted from the illumination device 50 to the inspection target. In the present embodiment, as the inspection camera 51, a CCD camera having sensitivity in the wavelength region of the light emitted from the illumination device 50 is adopted. Not limited to this, a CMOS camera may be adopted. A color CCD camera is used as the inspection camera 51 of the second inspection device 23 so that colors can be identified.

  Then, the image data (luminance image data or color image data) obtained by the image pickup of the inspection camera 51 is converted into a digital signal inside the inspection camera 51, and then is passed to the pass / fail judgment device 52 in the form of a digital signal. Is entered.

  The pass / fail judgment device 52 is configured as a so-called computer system including a CPU as an arithmetic unit, a ROM for storing various programs, and a RAM for temporarily storing various data such as arithmetic data and input / output data. . The quality determination device 52 includes an image memory 53, an inspection result storage device 54, a determination memory 55, an image / inspection condition storage device 56, a camera timing control device 57, a CPU, and an input / output interface 58.

  The image memory 53 stores the image data obtained by the inspection camera 51. The inspection is executed based on the image data stored in the image memory 53. Of course, the image data may be processed during the inspection. For example, it is conceivable to perform masking processing, shading correction, or other processing. The shading correction is for correcting variations in the lightness of light caused by the difference in position, because it is technically limited to uniformly illuminate the entire imaging range of the container film 3 or the like with the light of the illumination device 50. is there. The binarized image data obtained by performing binarization processing on the image data is also stored in the image memory 53.

  The inspection result storage device 54 stores the data of the quality judgment result, the statistical data obtained by statistically processing the data, and the like. The inspection result storage device 54 stores the quality determination result of the inspection target and the serial number for specifying the inspection target, which is set by the CPU and the input / output interface 58, in association with each other. In the present embodiment, each inspection device 22, 23, 26 determines whether each of the 10 tablets 5 contained in the PTP sheet 1 (tablet 5 for one PTP sheet) is good or bad. In 54, the pass / fail judgment results of each of the 10 tablets 5 and the serial numbers corresponding to these tablets 5 are stored in association with each other (see FIG. 7 and the like). Furthermore, when the tablet 5 is determined to be defective, the inspection result storage device 54 stores the inspection item that caused the defect determination.

  The judgment memory 55 is for storing various information used for judgment. Various types of information include criteria for determining quality (for example, a threshold value), a binarization threshold value for performing a binarization process, and data for defining an inspection target range (for example, tablets in image data. Information for identifying the five parts, design data regarding the relative positional relationship between the outer edge of the PTP sheet 1 and the pocket portion 2, and the like are included.

  Further, the determination memory 55 of the third inspection device 26 stores information for recognizing the identification tag information 7 attached to the PTP film 6.

  The image / inspection condition storage device 56 is composed of, for example, a hard disk device, and stores the date and time of defect determination, the inspection conditions used for the inspection, and the like.

  The camera timing control device 57 controls the imaging timing of the inspection camera 51. The image pickup timing is controlled based on a signal from an encoder (not shown) provided in the PTP packaging machine 10, and the inspection camera 51 takes an image every time the container film 3 or the like is fed by a predetermined amount.

  The CPU and the input / output interface 58 govern various controls in the inspection devices 22, 23, and 26. The CPU and the input / output interface 58 can transmit and receive signals to and from the constituent devices of the PTP packaging machine 10. This makes it possible to control the defective sheet discharge mechanism 45 and the like described above.

  In addition, the CPU and the input / output interface 58 set a serial number for each inspection target (the part that finally becomes the PTP sheet 1), and the set serial number is stored in the inspection result storage device 54 together with the quality determination result of the tablet 5 and the like. It is supposed to be remembered. The serial number is in such a manner that it increases by one toward the upstream side in the transport direction of the container film 3 and the PTP film 6.

  Further, the CPU and the input / output interface 58 can wirelessly send and receive signals to and from the integrated system 70. In the present embodiment, the CPU and the input / output interface 58 transmit the quality determination result of the tablets 5 and the serial numbers corresponding to these tablets 5 to the integrated system 70 each time the quality determination is performed. Further, the CPU and the input / output interface 58 can transmit information such as the pass / fail judgment result and the imaging data of the inspection camera 51 used when obtaining the pass / fail judgment result to the integrated system 70.

  The quality determination device 52 configured as described above performs quality determination of the inspection target based on the image data obtained by the inspection camera 51. The pass / fail determination device 52 performs, for example, binarization processing on the image data and block processing on the binarized image data, and determines the pass / fail of the inspection target based on various information stored in the determination memory 55.
