Description

  The present invention relates to an inspection system having an inspection unit that inspects an inspection object that finally becomes a PTP sheet, and a PTP packaging machine including the inspection system.

  A PTP sheet is comprised from the container film in which the pocket part in which the contents, such as a tablet, were filled was formed, and the cover film attached so that the opening side of a pocket part might be sealed with respect to the container film.

  The PTP sheet has a pocket portion forming means for forming a pocket portion on a belt-like container film, a filling means for filling the pocket portion with contents, and a sealing means for attaching a cover film to the container film. Manufactured by the machine.

  The pocket portion forming means includes, for example, a female mold having a molding recess, and sucks the container film that has become relatively flexible by heating by a predetermined suction means, and adsorbs the container film to the forming surface of the molding recess. This forms the pocket. Usually, the number of pocket portions corresponding to a plurality of PTP sheets is formed at a time by the pocket portion forming means.

  The filling means includes, for example, a drum having a plurality of recesses on the outer periphery and rotating in accordance with the transport speed of the container film. The drum is provided immediately above the container film, and the contents are sequentially filled into the pocket portions by rotating the drum containing the contents in the recesses.

  The sealing means includes, for example, a film feed roll having a plurality of depressions on the outer periphery, and a heating roll that is pressed against the film feed roll. In the sealing means, the cover film is attached to the container film by allowing the container film and the cover film to pass between both rolls while accommodating the pocket portion in the recess.

  Further, in the process of manufacturing the PTP sheet, an inspection unit is provided along the conveyance path of the container film. The inspection object that will eventually become a PTP sheet is inspected by the inspection means. In the inspection means, for example, inspection regarding abnormal appearance of the tablet or sheet portion such as cracks or chipping of a tablet or the like, mixing of foreign matter, sealing quality or the like is performed. Then, the quality of the inspection object is determined based on the determination result by the inspection means. The inspection object (PTP sheet) determined to be defective is discharged as a defective product by a predetermined discharging means.

  As a conventional inspection system, there is known a system that stores a defect occurrence time and a defect content when it is determined to be defective by inspection (see, for example, Patent Document 1).

JP 2006-220448 A

  By the way, in the said pocket part formation means, the situation where a damage | wound will arise in the specific position of a container film, for example due to the presence of a foreign material or a crack on a mold surface, etc. may occur.

  Further, for example, in the filling means, the clogging occurs in a specific concave portion provided in the drum, so that the content cannot be stored in the concave portion, and thus the specific pocket portion cannot be filled. Things can happen.

  Furthermore, for example, in the sealing means, a specific pocket portion may be crushed due to a foreign object or the like being clogged in the specific recess portion.

  Defects resulting from the abnormalities of each device as described above occur for every fixed number of inspection objects along the transport path. That is, the defect of the inspection target due to the abnormality of each device occurs periodically.

  However, in the inspection system for storing the above-described defect occurrence time and defect content, it is difficult to grasp the occurrence of periodic defects in the inspection object from the stored defect time and defect content, and an abnormality occurs in the apparatus itself. It may not be possible to recognize what is being done, or it may take time to recognize.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily grasp visually whether or not the occurrence of defects is periodic, and thus manufacture a PTP sheet. It is an object of the present invention to provide an inspection system and a PTP packaging machine that can more reliably and easily recognize an abnormality in a device for the purpose.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. In the manufacturing process of the PTP sheet in which the contents are stored in the pocket portion formed in the container film and the cover film is attached to the container film so as to close the pocket portion, Transport means for sequentially transporting the inspection object,
Inspecting at least one inspection item for each of the inspection objects, and inspection means for determining the quality of the inspection object in the inspection items;
An inspection system including a discharge unit that is provided downstream of the inspection unit along the conveyance path of the inspection target and discharges the inspection target that has been determined to be defective by the inspection unit;
Storage means for storing a pass / fail determination result of the inspection target in the inspection item;
Display means capable of displaying information indicating the pass / fail judgment result stored in the storage means;
In the display means,
Information indicating the pass / fail determination result of each inspection target is displayed in an order corresponding to the transport order of the inspection target, and is shifted and displayed along the arrangement direction of the information according to the transport position of the inspection target. ,And,
The inspection system is configured to shift-display the information to be inspected after passing the discharging means together with the inspection object before passing the discharging means.

  Examples of the “inspection item” include the presence or absence of abnormality in the contents and the cover film, the quality of the seal, and the presence or absence of foreign matter. The inspection item may be for only one element (for example, contents), or may be for a plurality of elements (for example, contents and foreign objects). In addition, “shift display” means that the information displayed on the display means is aligned in a predetermined direction at a predetermined time (for example, every predetermined period or every time a test object is conveyed by a predetermined amount). This means that the images are displayed in a staggered manner.

  According to the above means 1, the information indicating the pass / fail determination result of the inspection object is arranged in the order corresponding to the conveyance order of the inspection object, and not only the inspection object before passing the discharging means but also the discharging means in the display means. The inspection object after passing is also displayed. Therefore, it is possible to easily grasp visually whether or not a periodic defect has occurred in the inspection target. As a result, it is possible to more reliably and more easily recognize the presence / absence of an abnormality of the apparatus itself that induces periodic defects.

  Information indicating the pass / fail determination result of the inspection target is displayed so as to shift (flow) so as to correspond to the transport position of the inspection target. For this reason, it is possible to confirm the state of conveyance of the inspection object (where the inspection object is located in the conveyance path) and to more easily grasp the presence or absence of periodic defects in the inspection object.

  Furthermore, when a periodic defect has occurred, the occurrence cycle of the defect can be easily grasped. Therefore, by obtaining in advance a unique (or peculiar) defective product generation cycle when an abnormality occurs in each device, it is relatively easy to identify the device in which the abnormality has occurred based on the grasped failure generation cycle. be able to. As a result, it is possible to quickly take appropriate measures for the device in which an abnormality has occurred.

  “A plurality of inspection items are provided” means a case where there are a plurality of inspection items by one inspection means, or a case where a plurality of inspection means for inspecting at least one inspection item is provided. Moreover, it is good also as inspecting about multiple types of test | inspection content in each test | inspection item. For example, if the inspection item is abnormal in the contents (for example, tablets), for example, “tablet cracking”, “tablet fragment mixture”, “missing tablet”, “tablet shape / size difference”, “tablet missing” ”And“ tablet surface peeling ”are inspection contents (the inspection contents will be described later). Furthermore, in each inspection item, the inspection content may be different or may overlap. For example, the inspection related to one inspection content may be performed by one inspection means, and the inspection related to the same or related inspection content may be performed by an inspection means different from the first inspection means. .

  According to the means 2, information indicating the pass / fail determination result of each inspection item is displayed for each inspection target. Therefore, it is possible to easily recognize visually the contents of defects (inspection items in which defects have occurred) occurring in each inspection object.

  In addition, when an abnormality occurs in a certain apparatus for manufacturing a PTP sheet, a certain content defect may occur. Therefore, there is a case where it is possible to more easily identify the device causing the failure by grasping the content of the failure and examining / analyzing the occurrence of the failure.

  Further, for example, the apparatus A and the apparatus B used for manufacturing the PTP sheet are provided in this order along the conveyance path to be inspected, and if an abnormality occurs in the apparatus A, it is downstream of the apparatus A. The inspection means C makes a defect determination for a certain inspection item (for example, whether there is an abnormality in the contents). If an abnormality occurs in the apparatus A or B, the inspection means D downstream of the apparatus B There is a case where an equipment configuration is adopted in which a defect is determined for an inspection item that is the same as or related to the certain inspection item. In such a case, if an abnormality occurs in the apparatus A, a failure determination is made in both the inspection means C and D, and if an abnormality occurs in the apparatus B, a failure determination is made only in the inspection means D. According to the means 2, it is possible to easily grasp at which stage the defect determination occurs by viewing the information indicating the pass / fail determination result of each inspection item displayed in alignment for each inspection target. . Therefore, it is possible to more easily identify a device in which an abnormality has occurred. For example, in the above example, if periodic defect determination is made in both of the inspection means C and D, an abnormality has occurred in the apparatus A, and if periodic defect determination is made only in the inspection means D. The device B can be easily identified as having an abnormality.

  Means 3. The means 1 or 2 is characterized in that the display means is configured to be able to display the information indicating the pass / fail judgment result of each inspection object by dividing it into a predetermined number along the arrangement direction. Inspection system.

  According to the means 3, information indicating the pass / fail determination result is displayed in a predetermined number of pieces. For this reason, when a predetermined number is made to correspond to a predetermined defect occurrence cycle, when a defect corresponding to the cycle occurs, it can be understood very easily. As a result, it is possible to more easily grasp that an abnormality has occurred in the predetermined device itself.

Means 4. Control means for controlling display contents in the display means;
Input means connected to the control means,
The control means sets the predetermined number to a value based on the information input to the input means, and classifies information indicating the pass / fail judgment result of each inspection object on the display means based on the set value. The inspection system according to the above-mentioned means 3, wherein the inspection system is configured to be able to display.

  According to the means 4, the information indicating the pass / fail determination result of each inspection target can be displayed by being divided by an arbitrary number. For this reason, it is possible to display information corresponding to the defect occurrence period corresponding to each device. Therefore, it is possible to more easily catch the occurrence of periodic defects in the inspection target.

  Means 5. A PTP packaging machine comprising the inspection system according to any one of the above means 1 to 4.

  According to the means 5, the same operational effects as the means 1 and the like can be obtained.

  Hereinafter, an embodiment will be described with reference to the drawings.

  First, the PTP sheet 1 will be described. As shown in FIGS. 1A to 1C, the PTP sheet 1 includes a container film 3 having a plurality of pocket portions 2 and a cover film attached to the container film 3 so as to close the pocket portions 2. 4.

  The container film 3 is made of, for example, a transparent or translucent thermoplastic resin material that is relatively hard and has a predetermined rigidity, such as PP (polypropylene) or PVC (polyvinyl chloride). The cover film 4 is made of an opaque material (for example, an aluminum foil or the like) having a sealant made of, for example, a polyester resin applied on the surface.

  The PTP sheet 1 is formed in a substantially rectangular shape in a plan view, and two pocket rows composed of five pocket portions 2 arranged along the longitudinal direction of the sheet are formed in the lateral direction of the sheet. That is, a total of 10 pocket portions 2 are formed. Each pocket portion 2 contains one tablet 5 as the contents (see FIG. 1C).

  The PTP sheet 1 is manufactured into a sheet shape by punching a strip-shaped PTP film 6 (see FIG. 1B) formed from the strip-shaped container film 3 and the cover film 4.

  Next, an outline of the PTP packaging machine 11 for manufacturing the PTP sheet 1 will be described with reference to FIG.

  On the most upstream side of the PTP wrapping machine 11, the raw material of the strip-shaped container film 3 is wound in a roll shape. The drawer end side of the container film 3 wound in a roll shape is guided by a guide roll 13. The container film 3 is hooked 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 transports the container film 3 intermittently.

  Between the guide roll 13 and the intermittent feed roll 14, a heating device 15 and a pocket portion forming device 16 are sequentially arranged along the conveyance path of the container film 3. The pocket forming device 16 includes, for example, a female die (not shown) having a plurality of molding recesses (not shown) having a shape corresponding to the pocket portion 2 and the molding recesses via an exhaust passage communicating with the molding recess. A suction means (not shown) for sucking the container film 3 is provided. And in the state which the container film 3 was heated with the heating apparatus 15 and this container film 3 became comparatively flexible, the container film 3 is adsorbed by the said suction means to the formation surface of the said shaping | molding recessed part, A plurality of pocket portions 2 are formed at predetermined positions 3. In addition, formation of the pocket part 2 is performed in the interval between conveyance operations of the container film 3. Moreover, the pocket part 2 for several sheets (for example, six sheets) is formed at once by one process. The heating device 15 and the pocket portion forming device 16 constitute the pocket portion forming means in this embodiment.

  The container film 3 sent out from the intermittent feed roll 14 is hung in the order of the tension roll 18, the guide roll 19, and the film receiving roll 20. Since the film receiving roll 20 is connected to a motor that rotates at a constant speed, the container film 3 is transported continuously and at a constant speed. The tension roll 18 is in a state in which the container film 3 is pulled to the side where the container film 3 is tensioned by an elastic force, and prevents the container film 3 from being bent due to the difference in the transport operation between the intermittent feed roll 14 and the film receiving roll 20. The container film 3 is always kept in a tension state.

  A tablet filling device 21 is disposed between the guide roll 19 and the film receiving roll 20 along the conveyance path of the container film 3. The tablet filling device 21 has a function as a filling means for automatically filling the tablet 5 in the pocket portion 2. The tablet filling device 21 includes, for example, a drum (not shown) that rotates in synchronization with the transport operation of the container film 3 by the film receiving roll 20. The drum has a plurality of receiving recesses capable of storing the tablets 5 on its outer periphery, and the tablets 5 are dropped and stored one by one into the receiving recesses by opening a shutter (not shown) at predetermined intervals. . And the tablet 5 is sequentially filled into the pocket part 2 by the said drum which accommodated the tablet 5 in the accommodation recessed part rotating.

  Further, a pre-seal inspection section 22 is provided between the tablet filling device 21 and the film receiving roll 20. The pre-seal inspection section 22 is provided with a first inspection device T1, a second inspection device D, and a third inspection device A as inspection means in order from the upstream side. By these inspection devices T1, D, A, abnormalities relating to the tablet 5 and the container film 3 (sheet portion) are inspected. A more detailed configuration of each inspection apparatus T1, D, A will be described later.

  On the other hand, the original film of the cover film 4 formed in a band shape is wound in a roll shape on the most upstream side.

  The drawing 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. And the container film 3 and the cover film 4 pass between both the rolls 20 and 25 in a heating-pressing state, the cover film 4 is stuck to the container film 3, and the pocket part 2 is block | closed with the cover film 4. . Thereby, the PTP film 6 with which the tablet 5 was filled in each pocket part 2 is manufactured. The film receiving roll 20 and the heating roll 25 constitute a sealing means in this embodiment.

  The PTP film 6 sent out from the film receiving roll 20 is hung in the order of the tension roll 27 and the intermittent feed roll 28. Since the intermittent feed roll 28 is connected to a motor that rotates intermittently, the PTP film 6 is intermittently conveyed. The tension roll 27 is in a state in which the PTP film 6 is pulled toward the side to be tensioned by the elastic force, and prevents the PTP film 6 from being bent due to the difference in the transport operation between the film receiving roll 20 and the intermittent feed roll 28. The PTP film 6 is always kept in tension.

  A post-seal inspection unit 29 is provided between the film receiving roll 20 and the tension roll 27 along the transport path of the PTP film 6. The post-seal inspection section 29 is provided with a fourth inspection apparatus E and a fifth inspection apparatus S as inspection means in order from the upstream side. By these inspection devices E and S, abnormality relating to the tablet 5 and the PTP film 6 (sheet portion) is inspected. A more detailed configuration of each inspection apparatus E, S will be described later.

  The PTP film 6 sent out from the intermittent feed roll 28 is hooked in the order of the tension roll 31 and the intermittent feed roll 32. Since the intermittent feed roll 32 is connected to an intermittently rotating motor, the PTP film 6 is intermittently conveyed. The tension roll 31 is in a state in which the PTP film 6 is pulled toward the side to be tensioned by an elastic force, and prevents the PTP film 6 from being bent between the intermittent feed rolls 28 and 32.

  Between the intermittent feed roll 28 and the tension roll 31, a slit forming device 33 and a marking device 34 are sequentially arranged 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. The marking device 34 has a function of marking a predetermined position (for example, a tag portion) of the PTP film 6.

  The PTP film 6 sent out from the intermittent feed roll 32 is wound on the downstream side in the order of the tension roll 35 and the continuous feed roll 36. A sheet punching device 37 is disposed between the intermittent feed roll 32 and the tension roll 35 along the transport path of the PTP film 6. The sheet punching device 37 has a function as a sheet punching unit that punches the outer edge of the PTP film 6 in units of one PTP sheet.

  The PTP sheet 1 punched by the sheet punching device 37 is conveyed by a take-out conveyor 38 and temporarily stored in a finished product hopper 39. When a defect is determined by any one of the inspection devices T1, D, A, E, and S, a defective product signal is sent to a defective sheet discharge mechanism 40 as a discharge unit provided along the conveyance path of the take-out conveyor 38. Will be sent. Thereby, the PTP sheet 1 determined as defective is separately discharged by the defective sheet discharge mechanism 40 and transferred to a defective hopper (not shown).

  A cutting device 41 is disposed on the downstream side of the continuous feed roll 36. Then, the unnecessary film portion 42 constituting the remaining material portion (scrap portion) remaining in a strip shape after being punched 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. It is burned. The continuous feed roll 36 is in pressure contact with a driven roll, and performs a conveying operation while sandwiching the unnecessary film portion 42. The cutting device 41 has a function of cutting the unnecessary film portion 42 into a predetermined size and scrapping. The scrap is stored in the scrap hopper 43 and then disposed of separately.

  Each of the rolls 14, 19, 20, 28, 31, 32 and the like has a positional relationship in which the roll surface and the pocket portion 2 face each other. Since the recessed part which accommodates is formed, the pocket part 2 is not crushed fundamentally. Further, the feeding operation is performed while the pocket portion 2 is accommodated in the recesses such as the rolls 14, so that the intermittent feeding operation and the continuous feeding operation are performed reliably. The rolls 14, 20, 28, 31, 32 and the take-out conveyor 38 constitute the transport means of this embodiment.

  The PTP packaging machine 11 includes a main control device 60 and a display device 61 in addition to the various devices (means).

Various information (image data, inspection conditions, information on pass / fail judgment results, etc.) stored in the unit 29 (each inspection apparatus E, S) can be displayed.

  The display unit of the display device 61 is configured by a touch panel that functions as display means and input means, and is configured so that various information can be input to the main control device 60 therefrom. Of course, instead of or in addition to this, a configuration including a keyboard, a mouse, or the like as the input means may be adopted.

  Further, as shown in FIG. 6A, information indicating the pass / fail determination result of each inspection target is displayed in the order corresponding to the transport order of the inspection target and displayed on the display unit of the display device 61. As shown in FIG. 6B, the information is shifted and displayed one by one along the arrangement direction of the information in accordance with the transport position to be inspected. In this embodiment, “shift display” means that the information displayed on the display unit is displayed in a predetermined direction (in the drawing) at every predetermined timing or every time a test object is conveyed by a predetermined amount. The display is shifted by one column along the left direction. Further, the information is shifted and displayed for the inspection object before passing the defective sheet discharging mechanism 40 and the inspection object after passing the defective sheet discharging mechanism 40. Further, in the present embodiment, as “information”, coloring information using the first to third colors is adopted as described later.

  The display contents in the display unit will be described in detail. The numerical values arranged in the X direction (left and right direction in the figure) are the objects to be inspected (the container film 3 or the PTP film that becomes one PTP sheet by being punched before punching) 6 indicates an inspection area that corresponds to the punched PTP sheet 1 after punching), and a smaller numerical value indicates an inspection object positioned upstream in the conveyance direction. As shown in FIG. 15, in the display unit, the inspection target indicated by the numerical value “1” is located at the installation location of the first inspection apparatus T1, and the inspection target indicated by the numerical value “5” 2 The inspection object indicated by the numerical value “7” located at the installation location of the inspection apparatus D is located at the installation location of the third inspection apparatus A, and the inspection object indicated by the numerical value “13” is the fourth inspection.

Not limited to this, a CMOS camera may be employed. Note that a color CCD camera is adopted as the camera 51 of some inspection apparatuses such as the third inspection apparatus A so that the colors can be identified.

  The image data (luminance image data or color image data) captured by the camera 51 is converted into a digital signal inside the camera 51 and then input to the processing execution device 52 in the form of a digital signal.

  The processing execution device 52 is configured as a so-called computer system, similar to the main control device 60, and can execute various processes such as image processing.

  The processing execution device 52 includes an image memory 53, an inspection result storage device 54 as a storage unit, a determination memory 55, an image / inspection condition storage device 56, a camera timing control device 57, and a CPU and an input / output interface 58. Therefore, various image processing such as binarization processing and lump processing, defect determination processing (inspection processing), and the like can be performed.

  The image memory 53 stores two-dimensional image data (image data) of a captured image output from the camera 51. An inspection is executed based on the image data stored in the image memory 53. Of course, when the inspection is executed, the image data may be processed. For example, it is conceivable to perform processing such as masking processing or shading correction. The shading correction is for correcting variations in light brightness caused by a difference in position because there is a technical limit to uniformly illuminating the entire imaging range such as the container film 3 with the light of the illumination device 50. is there. Note that binarized image data obtained by performing binarization processing on image data at the time of inspection, masking image data subjected to masking processing, and the like are also stored in the image memory 53.

  The inspection result storage device 54 stores data such as coordinates relating to image data, quality determination result data for an inspection object, statistical data obtained by probabilistically processing the data, and the like. The quality determination result data and statistical data can be displayed on the display device 61 based on the control by the main control device 60. Further, the CPU and the input / output interface 58 can send a control signal to the main controller 60 based on these data.

  Further, as shown in FIGS. 10A to 10E, each inspection device T1, D, A, E, S is stored in the inspection result storage device 54 of each inspection device T1, D, A, E, S. Is stored together with the serial number (see FIG. 11) for specifying the inspection object. 10A to 10E illustrate only the storage state of the pass / fail judgment result in the inspection target to which the serial numbers LB1, LB2,... Are given, but in reality, the serial numbers LA1, LA2,. The pass / fail judgment result of the inspection target is also stored in the inspection result storage device 54 in the same manner.

  Returning to FIG. 3, the determination memory 55 stores determination values (threshold values, etc.) used for inspection. The determination value is set for each inspection content. The determination values used for the inspection include, for example, the dimensions of the PTP sheet 1, the pocket portion 2, the tablet 5, the shapes and dimensions of various window frames for demarcating various inspection regions, the threshold value for binarization processing, and the area determination Determination values, color reference values for color identification inspection, and the like. In addition, among the determination values, there are determination values that are determined by statistically measuring inspection measurement results for items determined to be non-defective items in past inspections, such as determination values for inspecting tablet area values.

  The image / inspection condition storage device 56 is constituted by, for example, a hard disk device. In the image / inspection condition storage device 56, the inspection contents such as “missing tablet” and “foreign matter on sheet” regarding the PTP sheet 1 (inspection target) determined to be defective by the inspection, date and time of defect determination, image data, and inspection are stored. The used inspection conditions are stored.

  The camera timing control device 57 controls the imaging timing of the camera 51. Such imaging timing is controlled based on a signal from an encoder (not shown) provided in the PTP packaging machine 11, and imaging by the camera 51 is performed every time a predetermined amount of the container film 3 or the PTP film 6 is sent.

  The CPU and the input / output interface 58 manage various controls in the inspection apparatuses T1, D, A, E, and S. For example, it has a function of executing various processing programs and transmitting / receiving various signals to / from the main control device 60. As a result, the main control device 60 can control the defective sheet discharge mechanism 40 and the like. In addition, the CPU and the input / output interface 58 specify a portion to be inspected in the container film 3 and the PTP film 6 based on the positions of the pocket portion 2 and the tablet 5 in the image data. And the said serial number according to a conveyance order is set with respect to the specified test object. The serial numbers to be inspected are increased one by one toward the upstream side in the transport direction.

  In the fourth inspection apparatus E, inspection is performed for the presence or absence of foreign matter and the presence or absence of abnormality in the tablet 5 (inspection item 4). Inspection items 4 include “tablet powder on sheet”, “hair on tablet”, “foreign matter on tablet”, “tablet cracking”, “tablet fragment contamination”, “hair on sheet”, “foreign matter on sheet”, Inspection contents such as “missing tablet”, “difference in tablet shape / size”, and “tablet missing” are included.

  In the fifth inspection apparatus S, an inspection is performed for sealing quality (inspection item 5). The inspection item 5 includes inspection contents such as “non-seal / wrinkle”.

  Here, each inspection content will be described. First, the inspection content regarding the presence or absence of abnormality in the tablet 5 is as follows.

  “Tablet cracking” is an inspection of whether or not the tablet 5 is cracked.

  The “missing tablet” is an inspection of whether or not the tablet 5 is filled in the pocket portion 2.

  The “tablet shape / size difference” is an inspection of whether or not the shape and size of the tablet 5 are compatible with the production type.

  “Tablet chipping” is an inspection of whether or not chipping has occurred in the tablet 5.

  “Tablet surface peeling” is an inspection of whether or not the surface layer of the tablet 5 is peeled.

  The “foreign matter on sheet” is an inspection of whether or not a large foreign matter having a size of several mm (for example, 5 mm) or more exists on the container film 3 or the PTP film 6.

  Note that “non-seal / wrinkle”, which is an inspection content relating to sealing quality, is an inspection of whether or not the cover film 4 is properly attached to the container film 3.

  Next, the inspection process performed in each inspection apparatus T1, D, A, E, S will be described based on the flowchart of FIG. This process is executed by the CPU and the input / output interface 58.

  First, in step S100, an inspection is performed on a predetermined inspection object. More specifically, based on the image data stored in the image memory 53, an abnormality or the like of the tablet 5 filled in the pocket portion 2 is inspected using a preset determination value.

  In the subsequent step S101, the result of the inspection is stored in each inspection result storage device 54 together with the serial number for specifying the inspection object (see FIGS. 10A to 10E).

  Next, display control processing of the display device 61 performed by the main control device 60 will be described based on the flowchart of FIG. The display control process is executed at regular time intervals.

  First, in step S200, a display control signal is output to the display device 61. The display control signal designates information indicating the pass / fail determination result of the inspection target received from each of the inspection devices T1, D, A, E, and S and the order of the pass / fail determination results set based on the table. Information. When the display control signal is output, in the display unit of the display device 61, for each numerical value arranged in the X direction, information on the pass / fail determination result in the inspection target indicated by the pointer information having the same number as the numerical value is obtained. The inspection items 1 to 5 are displayed side by side in the Y direction.

  Next, in step S201, it is repeatedly determined whether or not the inspection object has been conveyed by a predetermined amount until the inspection object is conveyed by a predetermined amount (for example, one sheet). The conveyance amount to be inspected is specified by a signal from an encoder (not shown).

  If it is determined that the inspection object has been conveyed by a predetermined amount (S201: YES), in the subsequent step S202, the serial number in the table [see FIGS. 9A to 9D] is updated. That is, as described above, for the pointer information “1”, a serial number that is one larger than the serial number set immediately before is newly set, and the pointer information one previous to the other pointer information is set. The serial number set for is shifted and set. Thus, when the next display control signal output (S200) is executed, the information indicating the pass / fail judgment result is displayed by being shifted by one in the X direction on the display unit of the display device 61.

  Next, display examples of pass / fail judgment results when an abnormality occurs in each device will be described with reference to FIGS.

  For example, in the heating device 15 and the pocket portion forming device 16, when an abnormality occurs in which the container film 3 is damaged due to the devices 15, 16, a predetermined number (for example, 5 Periodic flaws may occur in the container film 3 for each inspection object. When the container film 3 is scratched, the third inspection apparatus A, the fourth inspection apparatus E, and the fifth inspection apparatus S that inspect the sheet portion make a defect determination on the inspection items 3 to 5. Therefore, on the display unit of the display device 61, as shown in FIG. 7 (a), a display is made so that a predetermined number of inspection targets for which inspection items 3 to 5 are determined are periodically generated. The Thereby, the operator who confirmed the display can estimate that some abnormality has occurred in the heating device 15 and the pocket portion forming device 16.

  In addition, for example, when an abnormality such as foreign matter entering one recess occurs in the intermittent feed roll 14 positioned downstream of the heating device 15 and the pocket portion forming device 16, a predetermined number along the conveying direction. Some crushing may occur in the pocket portion 2 for every (for example, 12) inspection objects. When the pocket portion 2 is crushed, the tablet 5 filled in the crushed pocket portion 2 is inclined more than the normal pocket portion 2 filled. Therefore, the inspection devices T1, D, A, and E that inspect the tablet 5 are determined to be defective particularly in terms of “tablet shape / size difference”, and the inspection items 1 to 4 are determined as defective. Therefore, in the display unit of the display device 61, as shown in FIG. 7 (b), the inspection object for which the defect determination is made for the inspection items 1 to 4 corresponds to the passage timing of one recess of the intermittent feed roll 14. Thus, it is displayed that a predetermined number is periodically generated. Thereby, the operator who confirmed the display can presume that some abnormality has occurred in the intermittent feed roll 14.

  Furthermore, for example, when an abnormality occurs in the shutter of the tablet filling device 21, breakage such as a crack may occur in the tablet 5 for every predetermined number (for example, six) of inspection objects along the conveyance direction. When the tablet 5 is broken, the inspection items T1, D, A, and E for performing the inspection on the tablet 5 are judged as defective for the inspection items 1 to 4. Therefore, in the display unit of the display device 61, as shown in FIG. 8A, the inspection target for which the defect determination is made for the inspection items 1 to 4 corresponds to the passage timing of the shutter of the tablet filling device 21. , It is displayed as if it occurred periodically by a predetermined number. Thereby, the operator who confirmed the display can estimate that some abnormality has occurred in the tablet filling device 21.

  Further, for example, when foreign matter adheres to the film receiving roll 20 or the heating roll 25 (sealing means), a sealing failure is caused for every predetermined number (for example, 20) of inspection objects along the transport direction. Can occur. If a seal failure occurs, the fifth inspection device S makes a defect determination for the inspection item 5. Therefore, in the display unit of the display device 61, as shown in FIG. 8B, the inspection target for which the inspection item 5 is determined to be defective is the portion of the rolls 20, 25 where foreign matter adheres. Corresponding to the contact timing for the inspection object, a predetermined number of pieces are displayed periodically. Thereby, the operator who confirmed the display can estimate that some abnormality has occurred in the film receiving roll 20 and the heating roll 25.

  As described above in detail, according to the present embodiment, in the display device 61, the coloring information indicating the pass / fail determination result of the inspection target is arranged in the X direction in the order corresponding to the transport order of the inspection target, and the defective sheet Not only the inspection object before passing the discharge mechanism 40 (indicated by numerical values “1” to “20”) but also the inspection object after passing the defective sheet discharging mechanism 40 (indicated by numerical values after “21”). Stuff) is also displayed. Therefore, it is possible to easily grasp visually whether or not a periodic defect has occurred in the inspection target. As a result, it is possible to more reliably and more easily recognize the presence / absence of abnormalities in the devices (pocket portion forming device 15, film receiving roll 20, tablet filling device 21, etc.) that induce periodic defects. it can.

  In addition, since the information indicating the pass / fail determination result of the inspection target is displayed shifted (flowing) one by one in the X direction according to the transport position of the inspection target, the transport status of the inspection target (the inspection target is in the transport path) It is possible to confirm the presence or absence of a periodic defect in the inspection object.

  Furthermore, when a periodic defect has occurred, the occurrence cycle of the defect can be easily grasped. Therefore, by obtaining in advance a unique (or peculiar) defective product generation period at the time of occurrence of an abnormality in each apparatus, an apparatus in which an abnormality has occurred (such as the pocket portion forming device 15 or the like) Film receiving roll 20, tablet filling device 21 and the like) can be identified relatively easily. As a result, it is possible to quickly take appropriate measures for the device in which an abnormality has occurred. Further, by grasping the content of the defect and examining / analyzing the occurrence of the defect, it may be possible to more easily identify the device causing the defect.

  In addition, information indicating the pass / fail determination results of the respective inspection items 1 to 5 is displayed for each inspection target. Therefore, it is possible to easily recognize visually the contents of defects (inspection items in which defects have occurred) occurring in each inspection object.

  Furthermore, it is possible to easily grasp at which stage the defect determination occurs by looking at the information indicating the pass / fail determination result of each inspection item displayed in alignment for each inspection target. Therefore, it is possible to more easily identify a device in which an abnormality has occurred.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the case where the content is the tablet 5 is specified, but the type, shape, and the like of the content are not particularly limited. For example, food, electronic parts, and the like are used as the content. The structure filled may be sufficient.

You may comprise. In this case, if a predetermined number is made to correspond to a predetermined defect occurrence cycle, when a defect corresponding to the cycle occurs, it can be very easily grasped. As a result, it is possible to more easily grasp that an abnormality has occurred in the predetermined device itself.

  Further, for example, by inputting a numerical value to a predetermined input means (for example, a numeric keypad) connected to the main control device 60, the main control device 60 causes the display unit of the display device 61 to input each numerical value. You may comprise so that the information which shows the said quality determination result may be divided and displayed. In this case, the information indicating the pass / fail judgment result of each inspection object can be displayed by being divided by an arbitrary number, and information corresponding to the defect occurrence period corresponding to each apparatus can be displayed. Therefore, it is possible to more easily catch the occurrence of periodic defects in the inspection target.

You may comprise so that the information which shows a result may be divided and displayed. Specifically, for the main controller 60, for example, “5” for “pocket formation”, “6” for “tablet filling”, and “intermittent feed roll 14” For “12” and “seal”, an item button is associated in advance with a cycle in which a defect occurs in an inspection target when an abnormality occurs in the device indicated by the item button, such as “20”. Remember. When the item button KB is selected, the main controller 60 sets a numerical value corresponding to the selected item button from the stored contents (for example, when “pocket formation” is selected). Is set to “5”), and as shown in FIG. 13B, the display unit displays the information indicating the pass / fail judgment result of the inspection object in units of the set numerical values.

  In such a configuration, at the time of selection, by specifying an item button with a classification display that best matches the generation cycle of the defect in the inspection target, it is possible to determine which apparatus is the cause of the defect in each apparatus. Even a person who does not have knowledge about specific information (particularly, the occurrence cycle of a defect at the time of abnormality) can be identified easily and early.

  In FIGS. 12 and 13, the segmented display is performed by configuring the hatched regions and the regions that are not so as to alternately appear, but the segmented display method is not limited to this. . For example, the display may be performed by color classification, or the information indicating the pass / fail determination result may be displayed separately by displaying a predetermined number of pieces of information along the X direction.
