Description

  The present invention relates to an inspection apparatus that does not cause a work error caused by a human error in an inspection process performed manually, and an inspection method using the inspection apparatus.

  In many cases, the product production line has an inspection process in which a product is inspected after a packaging process in which the manufactured product is put in a packaging box. This inspection process, for example, inspects the product type and quantity, the presence / absence and type of labels to be affixed to the packaging box, and the presence / absence of accessories to be included, before removing the defective product. Is. This prevents defective products from leaking into the market.

  Patent Document 1 discloses an article packaging apparatus in which a packaging process and an inspection process are configured by a series of lines. The article wrapping apparatus includes a transport means such as a belt conveyor for transporting the packaging box, and a fitting means for fitting the top surface flap extending from the top cover of the packaging box into the packaging box and closing the packaging box, Tape attaching means for sealing the top surface flap and sealing inspection means for detecting the presence / absence of a label are provided. According to this article packaging apparatus, since the machine performs the packaging process and the inspection process continuously like a flow operation, it is possible to shorten the operation time in these steps and improve the production efficiency. Such an automated article packaging apparatus is suitable for mass production of each product type.

  On the other hand, when an article packaging apparatus such as Patent Document 1 is used for a packaging process or an inspection process in small-quantity multi-variety production in which a variety of products are produced in small quantities while producing a small amount of product per product, it corresponds to individual varieties. Equipment jigs and programs must be changed for each product type. Such an article wrapping device is poor in versatility, so that the man-hours required for changing jigs and the like increase, or errors due to the jigs accompanying the change occur, and the production efficiency and yield decrease on the contrary. Invite you. For this reason, the packaging process and the inspection process in the low-volume, multi-product production line are often performed manually by the operator. As a product that is produced in small quantities and many varieties, for example, there are ethical drugs, pharmacy drugs, or over-the-counter drugs that contain the same active ingredient but have different active ingredient contents and different capacities. Can be mentioned.

  However, manual packaging and inspection processes may result in defective products such as unapplied tapes, incorrect selection of the type of tape to be applied, and misaligned tapes. A so-called human error is likely to occur. In particular, in the inspection process, if an operation mistake that misses a defective product occurs, the defective product may flow out to the market. Since human errors occur due to human error and misunderstandings, it is difficult to avoid the occurrence of defective products and to investigate the cause of such errors compared to the case of defects caused by automated manufacturing equipment. is there.

JP-A-8-295301

  The present invention has been made to solve the above-mentioned problems, and has versatility suitable for small-quantity, multi-product production, and does not depend only on the visual inspection of the operator even in the inspection process performed manually. An object of the present invention is to provide an inspection apparatus and an inspection method using the inspection apparatus that can quickly and easily follow up the cause of defective products without causing work errors due to human errors.

  The inspection device of the present invention made to achieve the above object is a box in which a container in which contents are enclosed is accommodated and a kind display corresponding to the kind of the contents and a sealing tape are provided on the outer surface. An imaging unit for imaging the product type display and the sealing tape, and a storage for storing the captured image data of the imaging and the image reference data for each product type A comparison unit for comparing the photographed image data and the image reference data, and determining whether the photographed image data is within an allowable range of the image reference data for the product type display and the sealing tape, and determining the product type and the sealing tape. Appropriateness of appearance items selected from the presence / absence, type and position deviation, and the type of box corresponding to the product type, and / or pass all of them and pass, and at least one non-conformity fails A determination unit that determines whether or not the appearance of the test object is acceptable, and outputs at least one of the appearance results of the suitability of each appearance item according to the determination and the pass / fail of the test object appearance as a pass or fail signal And an informing unit for informing the appearance result by the signal.

  The inspection device includes, for example, a capturing unit that captures information for identifying the product type, and the storage unit extracts and stores the captured image data of the product type display image data and the sealing tape image data from the imaging. An imaging extraction storage unit, and a reference data storage unit that stores the image reference data of the product display reference data and the sealing tape reference data, and the product display image data and the product display reference data corresponding to the information The sealing tape image data and the sealing tape reference data corresponding to the information, and the determination unit detects a coincidence point of the read data, according to the coincidence level, Judgment of suitability of appearance items and / or judgment of acceptance / rejection of the test object appearance, and the output unit determines the appearance result for each suitability of each appearance item and the acceptance / rejection of the test object appearance. Flip, the said signal, and outputs, the notification unit is configured to broadcast differently the appearance results in response to the signal.

  The inspection apparatus further includes a weighing unit for measuring the weight of the test object, which is used for inspecting the weight of the test object containing the container enclosing the buffer material and the attachment. The storage unit stores the measured weight data and the permissible weight range for each product type, the comparison unit compares the weight data and the permissible weight range, and the determination unit determines that the weight data is the weight data. Judging whether the content is within or outside the allowable weight range, the weight selected from the excess or deficiency of the content and the variety, the presence or absence of an attachment, the presence or absence of cushioning material, the inclusion of another content in the content or the presence or absence of misencapsulation Judgment of suitability of items and / or judgment of pass / fail of specimen weight that passes with all conformance and fails with at least one nonconformity, and the output unit determines each weight item according to the judgment And at least the pass / fail of the test object weight Or outputs the weight result pass or as a fail signal Re, the notification unit, it is preferable that notifies the weight result of the signal.

  This inspection apparatus has, for example, a take-in unit that takes in information that identifies the product type, and the storage unit stores a weight storage unit that stores the weight data, an allowable weight range of the test object, and a buffer material missing weight range A reference data storage unit that stores the allowable weight range that is the weight range of the missing attachment and / or the buffer material / attachment missing weight, and reads the allowable weight range corresponding to the weight data and the information. Determining whether the data is within the range of the read data, determining the suitability of the weight item, and / or determining whether the test object weight is acceptable, and the output unit, The signal is output according to the weight result for each weight item suitability and the test object weight pass / fail, and the notification unit notifies the weight result differently according to the signal. .

  In the inspection device, for example, in accordance with the signal, the inspecting unit includes at least a sound generator that emits a sound, a vibrator that emits a vibration, a signal or a display represented by a display or a display change. Either.

  The inspection apparatus preferably includes a mounting table on which the test object is placed, and a discharge tool that pushes the test object out of the mounting table in response to the rejection.

  The inspection apparatus may have a counter that counts the number of the test objects that are accepted.

  The inspection method of the present invention is to inspect the inspection object using the inspection apparatus.

  In this inspection method, for example, by using an inspection apparatus having a counter, the total number of the specimens that are accepted by the counter and the number of the specimens that are rejected by the counter is the number of specimens subjected to the inspection. The inspection is terminated when the total number of inspections matches.

  Whether the inspection device of the present invention is a match between the photographed image data generated by the photographing unit and the reference image data based on the object information captured by the capturing unit that can be completely matched or allowed by the determination unit. Judging, it has the simple structure that the notification part reports the pass or failure of the appearance of the test object. Therefore, in the inspection process in small-quantity, high-mix production, which is often performed manually, inspection that does not rely only on the operator's visual inspection can be performed accurately and easily, and oversight of defective products due to human errors can be prevented. At the same time, there is no need to replace or update jigs or programs for each type of test object to be inspected, and it can be used for inspection of new products simply by updating reference image data.

  Since the inspection device compares the photographed image data with the reference image data and reports the acceptance or non-existence of the appearance of the test object, the operator is more accurate than visually observing the test object, and the appearance of the test object is defective. Recognize that it exists, and quickly investigate the cause of the failure. In addition, the inspection device can determine the failure every time the image data does not match, as a difference in the type of the test object, a missing seal tape, a different seal tape type, a misalignment of the seal tape, and a box type difference. Since the determination result is output, the operator can quickly and accurately recognize which of these causes the appearance defect.

  If the inspection device has a weighing unit, it will be possible to start from a single measurement of the weight data of the object to be tested. Since the presence / absence of the material can be determined and the determination result is output, the operator can quickly and accurately recognize which of these causes the weight defect. In addition, since the test object can be inspected based on two different standards of the weight data of the test object generated thereby and the captured image data generated by the imaging unit, a more reliable inspection can be performed. In addition, it is versatile because it can handle inspection of new products only by updating the allowable weight range.

  The captured image data is obtained by extracting feature points of data such as product type image data, tape image data, and tape position data from the imaging generated by the imaging unit, and the data generated by the weighing unit is specimen weight data. In addition, for each type of specimen, the storage unit has a product type reference image, a tape reference image, a tape position reference image, an allowable weight range for the specimen, a weight range for missing attachments, a weight range for missing cushioning materials, The inspection device can notify the operator of a number of causes of defects from the two types of data, image data and weight data, if the attached document missing weight range is stored.

  When the inspection apparatus has a mounting table and a discharge tool that moves the test object from the mounting table to the outside and pushes it out, a non-defective product and a defective product are determined depending on whether the determination unit passes or fails. Since it can be reliably separated, it is possible to reliably prevent a defective product from being mixed into a good product group.

  If the inspection device has a pass number counter, it can be compared with the actual number of inspection items passed to the shipping packaging box such as corrugated cardboard, and the excluded inspection non-passing actual number, so there is an over- and under-delivery of specimens in the shipping packaging box Can be detected.

  According to the inspection method of the present invention, the appearance of the test object, for example, the canopy surface or one side surface of the box is simply inspected by the suitability of a plurality of appearance items, and the plurality of test objects are only measured by measuring the weight. Depending on the suitability of the weight item, the test object can be inspected, and it is possible to accurately and reliably detect which item is non-conforming, visually, audibly and tactilely. In addition, the operator counts the non-defective product determined by the inspection device separately from the defective product, and determines whether or not it matches the total number of counters of the inspection device. You can proceed to the process.

  Next, each configuration will be described more specifically.

  Examples of the medicine 71 enclosed in the container 72 include solid medicines such as tablets, capsules, pills, troches, granules, and powders enclosed in a bottle-like container. The patch may be sealed in a bag-like container, or may be a liquid, extract, emulsion, syrup, or ointment sealed in a solid bottle-like or tube-like container. For example, if these medicines are tablets, there is tolerance for each tablet, but the tolerance of a predetermined quantity to be enclosed, for example, 100 tablets or 1000 tablets, becomes smaller as the number of tablets increases. The package insert is a so-called package insert, which is a manual that contains important information such as “indications / effects, usage / dose, precautions”. Further, the container 72, the buffer material 73, and the attachment 74 have almost no tolerance.

  The take-in unit 10 is a scanner 11 (for example) that can read a barcode or a QR code (registered trademark) representing the contents of the object information j such as the type, quantity, and lot number of the container 70 with a medicine container. (See FIG. 3). The capturing unit 10 may be a numeric keypad or a keyboard for inputting the object information j. An operator in the inspection process causes the acquisition unit 10 to acquire the inspection object information j. The capturing unit 10 outputs the test object information j to the information calling unit 51 in response to the call.

Reference data storage unit 20 is a memory capable of storing image reference data D ₁ and the weight data D ₂ as reference data D for each breed of pharmaceutical 71 for pharmaceutical accommodates bottles enter the carton 70. Specifically, the reference data D is subdivided into more detailed data for each inspection item of the carton 70 containing a medicine container. The image reference data D ₁ is created so that the reference image can be matched with the entire imaging of the product display image data p ₁ to be compared and the sealing tape image data p ₂ and the feature points of the image data. It is. Varieties display image data p ₁ and the sealing tape image data p ₂ as appropriate, the standard pattern character dictionary needed for pattern analysis, those prepared in advance as a standard pattern image.

  The photographing unit 30 is a digital camera 31 (see FIG. 3) that can photograph the external appearance of the medicine container carton 70. The digital camera 31 has a semiconductor imaging device that converts incident light into electric charges, such as CCD (Charged-Coupled Devices) and CMOS (Complementary Metal-Oxide-Semiconductor). As a result, the digital camera 31 can display the characters, symbols, figures, colors, the outline of the edge of the box 75, the shape of the sealing tape 76, the label, etc. as the product type display 75b attached to the outer surface of the medicine container carton 70. Characters, symbols, figures, contours, inflection points, line diagrams, and colors can be discriminated, recognized, or collated as the type display 76b and the pasting position.

The imaging unit 30 generates captured image data P and outputs it to the imaging extraction storage unit 35. Accordingly, the imaging extraction storage unit 35 performs digital processing on the entire imaging or a part of the imaging or digital processing for extracting feature points as necessary, and stores them as product display image data p ₁ and sealing tape image data p _2. It is. The imaging extraction storage unit 35 outputs the product type display image data p ₁ and the sealing tape image data p ₂ to the storage reading unit 52 as digital data.

The imaging extraction storage unit 35 extracts the product display image data p ₁ and the sealing tape image data p ₂ that are the captured image data P as image data of the entire imaging, or the characteristics of the entire imaging or the product display part or the sealing tape part. It is a memory that extracts and stores points, for example, characters, symbols, graphics, contours, contour inflection points, diagrams, colors, and combinations thereof. Such feature points are for pattern analysis. For example, the image is scanned, the layout is analyzed, the outline of the lid 75a of the taken medicine container containing carton 70, the box type display 75b as the character area, the reference line 75c as the ruled line area, the sealing tape 76 The contour and product type display 76b are determined, and feature points are extracted as characters, symbols, figures, contours, contour inflection points, line diagrams, colors, and combinations thereof. If necessary, the feature points are normalized with respect to size, inclination, blurring, and crushing, and feature parts such as start point, end point, inflection point, and color tone are re-extracted.

  The weighing unit 40 is a weight scale 41 (see FIG. 3) having a mounting table 42. The measuring unit 40 generates the weight data w by measuring the weight of the carton 70 containing the medicine container. The weighing unit 40 digitizes the weight data w as necessary and outputs the digitized data to the weight storage unit 45. The weight storage unit 45 outputs the weight data w to the memory reading unit 52 as digital data.

  The weight storage unit 45 is a memory capable of sequentially or sequentially storing weight data w for each individual of the medicine container-containing carton 70.

  These memories may be non-volatile memories such as hard disk drives, solid state drives, flash memories, and optical disks.

  The processing unit 50 includes an arithmetic information processing device such as a central processing unit (CPU) and a volatile memory such as a dynamic random access memory (DRAM) and a static random access memory (SRAM). Yes. A program for executing inspection is input in advance to the central processing unit. Further, the central processing unit controls the capturing unit 10, the reference data storage unit 20, the imaging unit 30, the imaging extraction storage unit 35, the weighing unit 40, and the weight storage unit 45. The processing unit 50 is programmed so that the information calling unit 51, the memory reading unit 52, the comparison unit 53, the determination unit 54, and the output unit 55 are sequentially driven by this program.

This program includes photographic image data P that is product type display image data p ₁ and sealing tape image data p ₂ , and image reference data D ₁ that is product type display reference data d _1-1 and sealing tape reference data d _1-2. Is for pattern analysis. In this program, the comparison by the comparison unit 53 and the determination by the determination unit 54 are performed by detecting matching points of data by pattern matching according to characters, symbols, figures, contours, inflection points, diagrams, and colors. It is determined whether or not the coincidence level is a complete coincidence or an allowable range. For example, optical character recognition portion of the varieties display image data p ₁ and the sealing tape image data p ₂ is compared with the standard pattern character dictionary if characters (OCR: Optical Character Recognition), a standard pattern as long as it is a non-character Pattern matching is performed with the image, and it is determined whether it is a complete match or an allowable range depending on whether the main points are common.

In this way, the presence or absence of the sealing tape 76, the position where the sealing tape 76 is applied, the characters of the product type indications 75b and 76b, etc. are discriminated or recognized by the processing unit 50 based on the imaging of the digital camera 31 of the imaging unit 30. Or For example, the product display image data p ₁ from the characters of the product display 75 b is the tape image data based on the appearance of the sealing tape 76, the tape position data based on the relative position between the outline of the sealing tape 76 and the reference line 75 c, and the sealing. sealing tape image data p ₂ containing tapes varieties image data based on the varieties display 76b attached to the tape 76, are respectively generated. These image data p ₁ and p ₂ are compared with the product display reference data d _1-1 and the sealing tape reference data d _1-2 of the image reference data D 1 by the comparison unit 53 as photographed image data P, and the determination unit 54 Suitability and / or appearance pass / fail is determined. Such comparison / judgment can be performed using a commercially available program.

This program also includes weight data w, test object allowable weight range _d2-1, buffer material missing weight range _d2-2, package missing weight range _d2-3, and cushioning material / attachment missing weight range. for the weight data D ₂ is d _2-4, or one that the determination by the comparison, and the determination unit 54 by the comparison unit 53 calculates and compares whether the range or is within the allowable range It is to judge whether or not.

  This program is programmed as follows. The determination unit 54 reads the reference data D matching the reference information D output from the capture unit 10 from the reference data storage unit 20 and temporarily stores it. Further, the determination unit 54 compares the captured image data P and the weight data w and the reference data D output from the imaging unit 30 and the weighing unit 40, respectively, so that they match or do not match, and are within the reference weight range. Whether or not the medicine containing carton 70 is accepted or rejected is determined each time. Further, the determination unit 54 determines which item is appropriate for the appearance result such as the suitability of each appearance item and the appearance result such as pass / fail of the test object, and the suitability of each weight item and the weight result such as pass / fail of the test object weight. It is output to the output unit 55 as an electrical signal that can be discriminated as to whether the item is determined to be acceptable or unacceptable.

  In accordance with the signal, the notifying unit 60 provides sound, for example, a buzzer, a warning sound, and a warning message indicating failure for the suitability of each appearance item and the appearance of the test object, the suitability of each weight item, and the test object weight. A sound generator such as a speaker 61, a ringer exemplified by a vibrator such as a vibrator for notifying with a vibration or vibration sound indicating failure, and / or a display panel 62 displaying an inappropriate item or failure. Or an indicator such as an indicator lamp 63 that lights up inappropriate items and failures separately (see FIG. 3). It is preferable that the sound emitted from the notification unit 60 and the display thereof are different depending on whether the determination by the determination unit 54 is acceptable or unacceptable for the medicine containing carton 70. Rather than displaying suitability / pass / fail, it is preferable from the viewpoint of the operator's cognition to notify the user of any of the items by the suitability or the failure of the test object. Such an informing unit 60 allows the worker in the inspection process to quickly recognize whether or not each item of the medicine container containing carton 70 is appropriate or not by hearing or vision.

  As shown in FIG. 1, for example, as shown in FIG. 1, the medicine-containing bottle-containing carton 70 is a bottle that is a container that encloses a granular medicine 71 that is a content and a cushioning material 73 that prevents breakage during transportation. 72 and a paper attachment 74 describing the medicine 71 are stored in the carton 75.

  The carton 75 is a rectangular parallelepiped paper box, and a lid 75 a extending on one side of the upper end of the carton 75 closes the top surface of the carton 75 so that it can be opened. A product type display 75b is attached to the outer surface of the lid 75a, which is a part of the carton 75, by printing. The type display 75b of the carton 75 is a combination of letters, numbers, and / or illustrations and colors, and shows, for example, the name, active ingredient content, and quantity of the medicine 71. A sealing tape 76 sealing the lid 75a across the lid 75a and one side surface of the carton 75 is stuck along a sticking reference line 75c indicating a tape sticking position. On the surface of the sealing tape 76, a product type display 76b which is the same as or a part of the product type display 75b is shown in a simplified manner. The product type display 75b may be attached only to the side surface of the carton 75.

  Note that the lid 75a may be extended at the opposite upper end sides of the carton 75 and overlapped or abutted on the top surface of the carton 75. In this case, the sealing tape 76 is affixed across the lid 75a and the side surface of the carton 75 so as to straddle the upper end sides of the carton 75 facing each other. The sticking reference line 75c may be a thin line or a broken line printed on the carton 75, or may be a perforation cut intermittently. The bottle 72 is preferably made of resin. The variation in individual weights of resin bottles is extremely small compared to glass bottles.

In the medical container bottle carton 70, the cushioning material 73 and the attachment 74 are manually put into the bottle 72 and the carton 75, respectively. In order to surely find those forgotten defects caused by human error in the inspection process, the weight data w generated by the weighing unit 40 and the test object allowable weight range d ₂ of the weight reference data D ₂ which is the reference data D. _-1 , buffer material missing weight range d _2-2 , attachment missing weight range d _2-3 , and buffer material / attachment missing weight range d _2-4 are compared by the determination unit 54.

The test object allowable weight range d _2-1 is a weight value having upper and lower limits. The buffer material missing weight range d _2-2 is the difference between the upper and lower limit values of the test object allowable weight range d _2-1 and the weight of the buffer material 73. The attachment missing weight range d _2-3 is This is the difference between the upper and lower limit values of the inspection allowable weight range d _2-1 and the weight of the attachment 74. Specifically, the upper limit value of the test object allowable weight range d _2-1 is represented by X + a when the median value is X and the tolerance is a, and the lower limit value is represented by X−a. The upper limit value of the buffer material missing weight range d _2-2 is expressed by X + a−Y when the buffer material weight Y (Y> 2a), and the lower limit value thereof is expressed by Xa−Y. The upper limit of the accompanying specification missing weight range d _2-3, when the ANNEX wt Z (provided that Z ≧ 2Y), represented by X + a-Z, the lower limit of which is represented by X-a-Z . Further, the upper limit value of the cushioning material / attachment missing weight range d _2-4 that the cushioning material 73 and the attachment 74 are absent is the buffering material missing weight range d _2-2 and the attachment missing weight range d _2-3. Is represented by X + a−Y−Z, and its lower limit is represented by X−a−Y−Z. Each weight range is shown in Table 1.

The tolerance of the weight of the buffer material and the tolerance of the weight of the attachment are almost 0 g, whereas the tolerance a of the test object is expressed as a variation of the entire content due to the weight variation of the contents, for example, tablets. Therefore, each weight range does not overlap because the test object allowable weight range d _2-1 (X ± a), the buffer material weight (Y), and the attached weight (Z) are in the above relationship. . For example, when X = 100 g, a = 1 g, Y = 3 g, and Z = 6 g, the test object allowable weight range d _2-1 is 101 to 99 g, and the buffer material missing weight range d _2-2 is 96 to 98 g. The missing weight range d _2-3 of the attachment is 93 to 95 g, and the missing weight range d _2-4 of the cushioning material / attachment is 90 to 92 g.

  The cause of the defect in the invisible carton 75 is specified only by the determination unit 54 determining whether the weight data w is within or outside each weight range. Specifically, the determination unit 54 determines that the buffer material 73 is missing when “X−a−Y ≦ w ≦ X + a−Y”, and when “X−a−Z ≦ w ≦ X + a−Z”. It is determined that the attachment 74 is missing or not. Further, the determination unit 54 determines a failure that both the cushioning material 73 and the attachment 74 are missing when “X−a−Y−Z ≦ w ≦ X + a−Y−Z”.

It is preferable that X> a + Y + Z, Y> 2a, Z ≧ 2Y (where a, X, Y, and Z are positive numbers). Accordingly, the allowable weight range d _{2-1 for} the test object, the deficient weight range d _{2-2 for} the buffer material, the deficient weight range d _{2-3 for} the attachment, and the deficient weight range d _2-4 for the shock absorbing material / attachment do not overlap. Therefore, it is possible to distinguish which of the weight items is inappropriate. Although the case of the weight of the cushioning material (Y) and the weight of the attachment (Z) has been shown, the weight of the attachment (Y) and the weight of the cushioning material (Z) may be used. By setting in this way, just by measuring the weight data w, it is possible to determine a plurality of items such as excess or deficiency in the quantity of contents, mixing or miscontainment of different contents, presence or absence of attachments, and presence or absence of cushioning materials. It becomes possible to do.

  The operation processes of the processing unit 50 and the notification unit 60 will be described with reference to FIG. FIG. 2 is a flowchart showing data processing in the inspection process using the inspection apparatus 1.

  In step S <b> 1, the capturing unit 10 captures the specimen information j by the scanner 11, for example, and outputs it to the storage / reading unit 52. Next, the memory reading unit 52 reads the reference data D corresponding thereto from the reference data storage unit 20 based on the object information j in step S2. The operator only needs to read the object information j using the scanner 11 for each type of the medicine container 70 to be inspected, change the jig or parts of the inspection apparatus 1, or change the program. No complicated work is required.

  First, in step S3, the algorithm is initially reset, and the past data of the test object is reset.

When the medicine container containing carton 70 is placed on the placing table 42, the photographing unit 30 photographs the top surface lid 75 a with the digital camera 31 and obtains imaging data. The imaging data is output from the imaging unit 30 to the imaging extraction storage unit 35, and the entire imaging is extracted as image data, or the feature points of the entire imaging or the type display part or the sealing tape part are extracted. stores the image data P of the display image data p ₁ and the sealing tape image data p _2. In addition, the measuring unit 40 measures the medical container-containing carton 70 and acquires the weight data w. Weight data w is output from the weighing unit 4, and the weight data w is stored in the weight storage unit 45.

  When the medicine container containing carton 70 is not on the mounting table 42, the captured image data P and the weight data w are not generated. Therefore, in step S4, the determination unit 54 determines whether the captured image data P and the weight data w can be read. The memory reading unit 52 determines that the carton 70 with the medicine container is placed on the placement table by reading the captured image data P and the weight data w, and proceeds to step S5. On the other hand, if the captured image data P and the weight data w cannot be read, the memory reading unit 52 determines that the medicine container containing carton 70 is not placed on the mounting table, and performs Step S3 again.

In step S5, the comparing unit 53 and determination unit 54, captured image data cultivars display image data p ₁ in P, and compare and contrast the varieties display reference data d _1-1 in the reference data D, both Match or mismatch is determined. When the determination unit 54 determines that the two match, the inspection apparatus 1 proceeds to step S6.

  The coincidence of the image data is not limited to being completely the same, and may be any as long as the determination unit 54 can determine, recognize, and collate the product type display. For example, defects that inevitably occur in the printing process and packaging process, such as slight misalignment of the product type display 75a, blurring, shading of colors, and adhesion of stains, are allowed and determined to be coincident. However, differences in feature points such as relative size differences, shape differences, and character differences are determined to be inconsistent.

  In step S5, when the determination unit 54 cannot determine the coincidence between the two, the determination unit 54 outputs, to the notification unit 60, a rejection of the difference in the type of the test object that the medical container containing carton 70 is different from the type to be inspected. To do. Thereby, the alerting | reporting part 60 alert | reports to a worker the different kind of medical container bottled carton 70 by step Sa5. When the operator removes the medicine container containing carton 70 on the mounting table, the inspection apparatus 1 returns to step S3.

In step S6, the determination unit 54 determines whether to load the sealing tape image data p ₂ in the captured image data P as the sealing tape. Determining unit 54 determines that the tape is attached to the lid 75a of the carton 75 by the load sealing tape image data p ₂ as sealing tape, the process proceeds to step S7. On the other hand determining unit 54, if not read the sealing tape image data p ₂ as sealing tape, it is determined that the sealing tape 76 to the carton 75 is not attached, the output unit 55 the failure of sealing tape missing, the notification unit 60 Output to. Thereby, the alerting | reporting part 60 alert | reports a sealing tape missing of the medicine container containing carton 70 to an operator by step Sa6. When the operator removes the medicine container containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3. When the test object is a medicine container containing carton 70 having a plurality of sealing tapes 76, not only the presence / absence of the sealing tape 76 but also the lack of the sealing tape 76 is determined by the determination unit 54 in step S <b> 6. The inspection device 1 may be configured.

In step S7, the determination unit 54 determines that the sealing tape image data p ₂ in the captured image data P, and comparing the sealing tape reference data d _1-2 in the reference data D match or mismatch therebetween. When the determination unit 54 determines that the two match, the inspection apparatus 1 proceeds to step S8.

  The coincidence of the image data is not limited to being completely the same, and it is sufficient that the determination unit 54 can determine, recognize, and collate a prescribed sealing tape. For example, defects that are inevitably generated in the printing process and packaging process, such as slight misalignment of the sealing tape 76, blurring of its kind display 76b, shading of color, and adhesion of dirt, are allowed and determined to be coincident. The However, the difference in the feature points such as the size of the sealing tape 76 and the type display 76b character thereof is determined to be inconsistent.

  In step S7, when the determination unit 54 determines a mismatch between the two, the determination unit 54 determines the rejection of the sealing tape type difference that is different from the type to which the sealing tape 76 is to be applied, and this is determined by the output unit 55. The information is output to the notification unit 60. The notification unit 60 notifies the operator of the different types of sealing tape 76 in step Sa7. When the operator removes the medicine container-containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3.

In step S8, the determination unit 54, a sealing tape image data p ₂ in the captured image data P, and comparing the sealing tape reference data d _1-2 in the reference data D, a predetermined range in the example patch baseline 75c It is determined whether it is within. Thereby, whether the sealing tape 76 in a position range tolerated the sealing tape reference data d _1-2 is attached is determined. If the allowable position range of the sticking position of the sealing tape 76 is determined, the inspection apparatus 1 proceeds to step S9.

  When it is determined in step S <b> 8 that the sealing tape 76 sticking position is outside the allowable position range, the determination unit 54 determines a failure of the sealing tape 76 sticking position deviation, and the output unit 55 notifies the notification unit 60. Is output. The notification unit 60 reports this failure to the worker in step Sa8. When the operator removes the medicine container-containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3.

Determining unit 54 at step S9, it is determined whether the weight data w is within the buffer material missing weight range d _2-2. If the weight data w by the determination unit 54 is determined to be missing weight range d _2-2 outside the buffer material, the checking apparatus 1 goes to step S10. On the other hand, when the determination unit 54 determines that the weight data w is within the buffer material missing weight range d _2-2 , the determination unit 54 determines that the buffer material is missing and outputs the result to the notification unit 60 by the output unit 55. Thereby, the alerting | reporting part 60 alert | reports to an operator that the insertion of the buffer material 73 is forgotten in step Sa9. When the operator removes the medicine container-containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3.

In step S10, the determination unit 54 determines whether or not the weight data w is within the accompanying specification missing weight range d _2-3. If the weight data w is determined with the accompanying specification missing weight range d _2-3 outside the judging unit 54, the inspection apparatus 1 goes to step S11. On the other hand, when the determination unit 54 determines that the weight data w is within the attachment missing weight range d _2-3 , the determination unit 54 determines that the attachment is missing, and outputs it to the notification unit 60 by the output unit 55. Thereby, the alerting | reporting part 60 alert | reports to a worker that the attachment 74 is forgotten in step Sa10. When the operator removes the medicine container-containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3.

In step S <b _> 11, the determination unit 54 determines whether the weight data w is within the cushioning material / attachment missing weight range d _2-4 . When the determination unit 54 determines that the weight data w is outside the buffer material / attachment missing weight range d _2-4 , the inspection apparatus 1 proceeds to step S12. On the other hand, if the determination unit 54 determines that the weight data w is within the buffer material / attachment missing weight range d _2-4 , the determination unit 54 determines a failure of the buffer material / attachment missing, and the output unit 55 notifies the notification unit 60 of the failure. Is output. Thereby, the alerting | reporting part 60 alert | reports to a worker that the buffer material 73 and the attachment 74 are forgotten to put in step Sa11. When the pharmaceutical container containing carton 70 on the mounting table 42 is removed by the operator, the process returns to step S3.

In step S12, the determination unit 54 determines whether or not the weight data w is within the test object allowable weight range d _2-1 . When the determination unit 54 determines that the weight data w is within the test object allowable weight range d _2-1 , the determination unit 54 determines whether the medicine container containing carton 70 is acceptable, and the process proceeds to step S13. In step S <b> 13, this pass is output by the output unit 55 to the notification unit 60. Further, the notification unit 60 reports a non-defective product in the medicine container containing carton 70, and the inspection is completed. On the other hand, when the determination unit 54 determines that the weight data w is out of the test object allowable weight range d _2-1 , the determination unit 54 determines a disqualification such as a difference in medicine such as a variety of medicine 71 or an excess or shortage, Is output to the notification unit 60. Thereby, the alerting | reporting part 60 alert | reports a pharmaceutical difference to an operator by step Sa12. When the operator removes the medicine container-containing carton 70 on the mounting table 42, the inspection apparatus 1 returns to step S3.

  In this way, the inspection apparatus 1 repeats steps S1 to S13 for each medicine container-containing carton 70. The operator simply repeats the simple operation of placing or removing the medicine container containing carton 70 as the test object on the mounting table 42, and the inspection device 1 enters the medicine container after passing through steps S1 to S13. Since the pass or fail of the carton 70 is determined, a human error such as an oversight or a mistake is not generated, and a defective product is not mixed into the non-defective product group. Furthermore, since the inspection apparatus 1 semi-automates the inspection process performed manually, the burden on the operator can be reduced.

  In addition, the inspection device 1 acquires two data of the captured image data P and the weight data w of the medical container containing carton 70 on the mounting table 42 at the same time, and compares this with the reference data D, so that the medical container bottle is obtained. Different types of input cartons 70, forgetting to attach sealing tape 76, different types of sealing tape 76, misalignment of sealing tape 76, missing cushioning material 73, missing attachment 74, missing cushioning material 73 and attachment 74, and medicine Eight items of cause of defects such as 71 different types and excess and deficiency can be specified by only two types of image shooting and weight measurement. In particular, since the inspection device 1 can identify the deficiency of the cushioning material 73 and / or the attachment 74 that is difficult to identify by the appearance, the weight of the medicine-containing bottle carton 70 can be used to investigate the cause of these defects. There is no need to re-measure or to open the carton 75. The inspection device 1 improves the productivity by preventing the recurrence of defects by helping the operator to quickly perform the inspection work, as well as assisting in the prompt investigation of the cause of defects in the product production line and the planning of countermeasures. Contribute to.

  In addition, step S5-S12 is not restricted to the order shown in FIG. 2, The order before and after each step can be replaced. Further, a step may be omitted or a new step may be provided depending on the item to be inspected. Although only steps S5 to S8 for comparing image data may be included, reliability is improved if steps S5 to S12 for comparing the image data and the weight allowable range are included.

  An example of the appearance of such an inspection apparatus 1 is shown in FIG. The inspection device 1 includes a scanner 11 as a take-in unit 10, a digital camera 31 as a photographing unit 30, a weight scale 41 as a weighing unit 40, a speaker 61 as a notification unit 60, a display panel 62, and an indicator lamp 63, A personal computer 80 in which a nonvolatile memory as the reference data storage unit 20 and a CPU and a volatile memory as the determination unit 54 are combined is integrated on the work table 90.

  The work table 90 is a general-purpose one having legs welded to four corners of an upper shelf 92 and a lower shelf 93, respectively. A caster 91 is attached to the lower end of the leg. Thus, the operator can easily move the inspection apparatus 1 to a place suitable for performing the inspection process in the factory by pushing or pulling the work table 90. On the upper shelf 92 of the work table 90, a weight scale 41, an elevator 94 that supports the digital camera 31 disposed immediately above it, and a display box 81 are fixed and aligned with the weight scale 41. A work instruction sheet 96 is placed. The scanner 11 is housed in a holder attached to the side of the upper shelf 92 beside the work instruction sheet 96. A personal computer 80 is fixed to the lower shelf 93 of the work table 90.

  The elevator 94 includes an elevating shaft 94a that is rotatably supported from the upper end to the lower end of the vertically long frame, and a handle 94b that is connected to the elevating shaft 94a at the upper end of the frame and rotates it. The elevating shaft 94a and the stay 94c to which the digital camera 31 is attached are screwed together. When the handle 94b is turned, the elevating shaft 94a rotates and the digital camera 31 can be moved in the vertical direction. As a result, the distance from the medicine container containing carton 70 on the mounting table 42 is increased or decreased, and the focus of the digital camera 31 is adjusted to the lid 75a. The digital camera 31 may be attached to the stay 94 so that one side of the box 75 can be photographed together with the lid 75a or instead of the lid 75a. The digital camera 31 is electrically connected to a display panel 62 fixed to the display unit box 81 and a personal computer 80 via a cable.

  The mounting table 42 of the weighing scale 41 has a rectangular shape, and an L-shaped positioning tool 43 is mounted along the side on the elevator 94 side and the side on the central part side of the upper shelf 92 adjacent to this side. 42 is erected. The operator simply slides and places the medicine container bottle carton 70 along the positioning tool 43 on the mounting table 42 so as to contact the L-shaped right-angled portion, and the medicine container container carton 70 is attached to the digital camera 31. It is positioned directly below. The weight scale 41 is electrically connected to a weight display 44 fixed to the personal computer 80 and the display box 81 via a cable.

  The display box 81 has a rectangular parallelepiped shape, and a display panel 62, a weight display 44, and a counter 95 are fixed to the front surface thereof, and a speaker 61 and an indicator lamp 63 are fixed to the top surface thereof. The counter 95 indicates the cumulative number of cartons 70 containing medicine containers that have been passed by the determination unit 54, that is, determined to be non-defective products. The weight display 44 displays the weight of the medicine container containing carton 70 measured by the weighing scale 41.

  The speaker 61 rings according to the pass or fail of the medicine container containing carton 70 determined by the determination unit 54. The tone emitted from the speaker 61 is not particularly limited, and examples thereof include a buzzer sound, an electronic sound, music, a voice of a person telling that the product is a good product or a defective product. More preferably, the human voice is a word that conveys the type of failure that is the cause of failure, such as “tape is not applied”. The indicator lamp 63 is, for example, a laminated indicator lamp in which a green lamp, a yellow lamp, and a red lamp are laminated, and it is preferable to determine that the inappropriateness of each item is displayed according to each lighting.

  The display panel 62 displays various information related to the inspection work. For example, the image photographed by the digital camera 31, the object information j read by the scanner 11, the execution status of each step S1 to S13, and the display of the cause of failure in each step Sa5 to Sa12 can be mentioned. The inspection apparatus 1 may be configured to collectively display information indicated by the weight indicator 44 and the counter 95 on the display panel 62. The display panel 62 may be a touch panel that can input the object information j. According to this, since the take-in unit 10 is configured by the display panel 62 instead of the scanner 11, the inspection device 1 is made to read the inspection object information j by the operator pressing the display panel 62 with a fingertip and operating it. be able to.

  Since the notification unit 60 includes the speaker 61, the display panel 62, and the indicator lamp 63, it is possible to notify the worker acoustically and visually about the pass or fail of the medicine container containing carton 70 in particular. it can. In particular, the notification unit 60 has a different type of carton 70 containing a medicine container, forgetting to attach the sealing tape 76, a different type of the sealing tape 76, a deviation in the applied position of the sealing tape 76, no buffer material 73, no attachment 74, buffer material. 73 and attachment 74 missing, and the dissatisfaction that the medicine 71 is different or excessive or insufficient, that is, for each cause of failure, a different sound is generated, a different screen is displayed, or blinking and lighting with different colors and timings. The worker can recognize the cause of the defect only by listening to the sound emitted from the speaker 61 or by looking at the display panel 62 or the indicator lamp 63. In addition, it is preferable that the alerting | reporting part 60 does not stop operation | movement of the alerting | reporting part 60 unless the medicine container bottle carton 70 made disqualified is removed.

  As described above, the inspection device 1 can be easily and inexpensively manufactured by simply attaching necessary parts to the general-purpose workbench 90 and introduced into the inspection process. Further, the inspection apparatus 1 is small in size because all the components can be concentrated on the work table 90, and contributes to the effective use of the space in the factory. As a result, the inspection device 1 is rich in versatility that eliminates the need for a large-scale device such as a belt conveyor or a dedicated device for each type of product, and can improve the production efficiency of a small number of products.

  The inspection method of the present invention using this inspection apparatus 1 will be described.

  The operator can move the inspection apparatus 1 to a place suitable for performing the inspection process by pushing or pulling the work table 90 in the factory. An operator can store a product container (not shown) in which a carton 70 containing one hundred lots to several thousands of medicine container bottles, an empty good container for storing good products, and a defective product for storing defective products. An empty defective container is placed beside the work table 90. Each container preferably has a different color and shape. This prevents human errors such as mistakes in the container 70 containing the pre-inspection medicine container bottle 70, the non-defective medicine container bottle carton 70, and the defective medicine container bottle carton 70, and ensures that they are mutually connected. Can be isolated.

  Next, the worker holds the scanner 11 over the object information j attached to the work instruction sheet 96 and causes the inspection apparatus 1 to read the object information j. Thereby, the inspection apparatus 1 executes steps S1 and S2.

  The operator takes out the medicine container containing carton 70 from the container and lightly presses it against the positioning tool 43 of the mounting table 42. The inspection apparatus 1 executes steps S3 to S12 in order. Thereby, the determination part 54 of the inspection apparatus 1 determines the pass of the medicine container containing carton 70, and the alerting | reporting part 60 reports a non-defective product. The counter 95 counts the number of good products and displays the accumulated number. By receiving this notification visually and audibly, the operator recognizes the end of the non-defective product and the inspection of the medicine containing carton 70, and then removes the medicine containing carton 70 from the mounting table 42, Put in a container.

  On the other hand, when the notifying unit of the inspection device 1 reports any failure of the medical container containing carton 70 in any one of Sa5 to Sa12, the worker recognizes the defective product in the medical container containing carton 70 and the end of the inspection. Then, it is removed from the mounting table 42 and placed in a defective container.

  By repeating the above operation, the inspection of all the medicine container containing cartons 70 accommodated in the product container is completed. The worker counts the number of medicine container bottles 70 stored in the non-defective container, compares this number with the total number displayed on the counter 95, and the inspection process is performed only when both match. Exit. On the other hand, if the two do not match, the operator can recognize the possibility that the defective or uninspected pharmaceutical container containing carton 70 is mixed into a non-defective container, or vice versa, so that the defective product does not flow out to the next process.

  As described above, according to the inspection method of the present invention, determination of each non-defective product in the carton 70 containing the medical container using the inspection device 1, and the accumulated number determined as the non-defective product and the medical container bottle in the non-defective container. By comparing with the count of the input carton 70, it is possible to reliably prevent work errors caused by human errors and prevent defective products and uninspected products from flowing out to the market.

  FIG. 4 shows a partially omitted perspective view of another aspect of the inspection apparatus 1. As shown in FIG. 2A, the inspection apparatus 1 has an actuator 97 at the lower end of the elevator 94. The actuator 97 is a discharge tool that pushes and moves the medicine container containing carton 70 on the mounting table 42 out of the mounting table 42. The actuator 97 includes a piston 97a having a flat surface facing the mounting table 42, a piston rod 97b connected to the piston 97a, and a cylinder 97c that accommodates the piston rod 97b in a removable manner. Yes. The cylinder 97c is fixed to the elevator 94 on the work table 90 via a fixture 98 by screwing.

  A pump (not shown) that allows fluid such as air and oil to flow into and out of the cylinder 97 c is connected to the actuator 97. As the fluid enters and leaves the cylinder 97c, the piston rod 97b protrudes toward the mounting table 42 or is stored in the cylinder 97c. Accordingly, the piston 97a can reciprocate across the mounting table 42.

  When the inspection apparatus 1 determines that the medicine containing bottle carton 70 is rejected, as shown in FIG. 4B, the piston rod 97b protrudes from the cylinder 97c and the piston 97a comes into contact with the side surface of the medicine containing bottle containing carton 70. . When the piston rod 97b further protrudes, the medicine containing carton 70 is pushed away from the actuator 97, and finally pushed out of the mounting table 42 and dropped to be removed. The dropped carton-filled carton 70 is stored in a defective container (not shown) placed at the dropping point. On the other hand, when the inspection device 1 determines that the medicine containing carton 70 is acceptable, the actuator 97 does not operate.

  As described above, the inspection apparatus 1 has the actuator 97 that operates in response to the acceptance or rejection of the medicine container jar 70, so that only when the medicine container jar 70 is judged to be unacceptable. The non-defective medicine container containing carton 70 is automatically removed from the mounting table 42. Thereby, since the separation between the non-defective product and the defective product does not depend on the work of the worker, the inspection device 1 can more reliably prevent the occurrence of the work error due to the human error.

  The inspection apparatus and inspection method of the present invention are used to inspect an object to be inspected such as a carton containing a medicine container in an inspection process at a production site, and to determine whether it is a non-defective product or a defective product.
