Description

  The present invention relates to a weight sorter that is installed on a production line and weighs and sorts articles to be inspected while being transported.

  Weight sorters are installed in production lines for various products. In production lines for packed foods and the like, for example, a combination line, a packaging machine, a metal detector, and a weight sorter May be configured.

  The combination weigher performs a combination operation so that articles such as candy and snacks are in an appropriate weight range, and discharges the articles in the appropriate weight range, and the packaging machine wraps the articles discharged from the combination weigher in a packaging material. And carry it out as a package. The metal detector checks whether metal is mixed in the package carried out of the packaging machine.The weight sorter determines that the weight of the package passing the metal detector is good or defective within the specified weight range. The presence or absence of a defective product and a defective product out of the predetermined weight range and a defective product mixed with metal are removed to the outside of the transport line by a sorting device at a later stage.

  In such a production line, if a failure occurs in any one of the devices constituting the production line, the entire production line may have to be stopped. In order to bring a stopped production line into operation early, it is necessary to identify the cause of the failure immediately and take appropriate measures.

  Patent Literature 1 discloses that an abnormality in a seal of a packaging machine in a preceding stage of a weight sorter is detected based on excess or deficiency of a weighed value measured by a weight sorter (weight checker) so that appropriate measures can be taken at an early stage. Is described.

JP 2000-229611 A

  However, Patent Literature 1 discloses that a seal abnormality of a packaging machine in a preceding stage of a weight sorter is detected based on excess or deficiency of a weighing value, but does not disclose detection of other defects. However, it can only deal with a limited number of problems.

  As described above, various devices such as a combination weigher, a packaging machine, and a metal detector are installed in the preceding stage of the weight sorter, so that various problems occur after the operation of the production line. Therefore, in the weight sorter, an abnormality may occur in which many of the inspected articles are sorted as defective.

  As described above, when an abnormality such that many of the inspected articles are sorted out as defective products by the weight sorter due to various inconveniences of the apparatus at the preceding stage occurs, various inconveniences can be easily dealt with. It is desired.

  The present invention has been made in view of the above points, and when an abnormality occurs such that many of the articles to be inspected are selected as defective products by a weight sorter, the abnormality is dealt with. The purpose is to make it easy to deal with.

  In order to achieve the above object, the present invention is configured as follows.

(1) The weight sorter of the present invention is a weight sorter that weighs articles to be inspected while transporting them, and sorts them into good products within a predetermined weight range and defective products outside the predetermined weight range.
A storage unit in which the weight value change pattern outside the predetermined weight range is stored in advance as an abnormal pattern;
An input operation unit configured to input coping information for coping with the abnormal pattern, which is stored in the storage unit in association with the abnormal pattern,
A determination unit that determines whether the pattern of the weight value change of the inspected article to be weighed is the abnormal pattern,
By the determination unit, when it is determined that the failure pattern, the address information associated with the abnormal pattern, when stored in the storage unit, and its possible broadcast to address notification unit Prepared,
The abnormal pattern is a pattern of a change in the weight value of the article to be inspected, which is caused by a failure of a device at a preceding stage disposed on the upstream side in the transport direction of the article to be inspected from the weight sorter,
The coping information is information for coping with the problem of the preceding device .

  The abnormal pattern may be any pattern of weight change outside the predetermined weight range, and the pattern of the weight change is an arbitrary pattern. Since the weight value is a non-defective product, it is preferable to use a weight value change pattern to be reported as abnormal.

  The number of abnormal patterns may be one, but it is preferable that the number of abnormal patterns is plural, and when there are plural abnormal patterns, it is preferable that the coping information is individual coping information for each abnormal pattern.

  The coping information for coping with the abnormal pattern is information for coping so that the abnormal pattern does not occur.

  According to the weight sorter of the present invention, a pattern of a weight value change outside a predetermined weight range to be sorted out as a defective product is stored in the storage unit in advance as an abnormal pattern to be reported as an abnormal condition, and is measured by the determining unit. If the pattern of the change in the weight value of the inspected article is determined to be an abnormal pattern, that is, if an abnormality has occurred, a notification is issued when the handling information for the abnormal pattern is stored in the storage unit. The unit can notify the coping information. Thereby, the worker who performs maintenance or the like can take appropriate measures based on the notified countermeasure information, and can easily cope with the occurrence of an abnormality as compared with the case where there is no countermeasure information.

  When the handling information is not stored in the storage unit, for example, when the handling information is not stored in the storage unit, for example, at the beginning when the weight sorter is installed and the first operation is started, an abnormality occurs. However, it is not possible to notify the coping information, and the worker who performs maintenance or the like cannot take appropriate measures based on the coping information.

  In this case, when the worker can identify the cause of the abnormality and take appropriate measures to prevent the abnormality from occurring, the appropriate measures are input as the response information to deal with the abnormal pattern. The input can be made by operating the operation unit and stored in the storage unit.

  Therefore, after that, when the same abnormal pattern occurs due to the same cause, since the coping information is stored in the storage unit, the coping information can be notified, and the worker can notify the coping information to be notified. Based on this, it can be easily dealt with.

Thus, initially, even if the coping information is not stored in the storage unit, when an abnormal pattern occurs and a worker performing maintenance or the like can identify the cause and take appropriate measures, By operating the input operation unit and storing the appropriate measures in the storage unit as coping information, the coping information can be enhanced as the weight sorter is used, and when an abnormal pattern occurs Is easier to deal with.
Further, when an abnormal pattern occurs, when the handling information for dealing with the abnormal pattern is stored in the storage unit, the notifying unit can notify the handling information, so that the worker is notified. Based on the coping information, it is possible to solve the problem of the preceding device.

In a preferred embodiment of the weight sorter (2) present invention, in the storage unit, together with the failure pattern, the address information is stored in advance in association with the abnormal pattern.

  According to this embodiment, for example, when the manufacturer of the weight sorter has grasped the handling information for dealing with the abnormal pattern, the storing unit stores the handling information together with the abnormal pattern in advance. By doing so, the handling information can be used from the beginning when the weight sorter is installed and the first operation is started.

( 3 ) The weight sorter of the present invention is a weight sorter that weighs an article to be inspected while transporting the same and sorts it into a non-defective product within a predetermined weight range and a defective product outside the predetermined weight range,
A storage unit in which the weight value change pattern outside the predetermined weight range is stored in advance as an abnormal pattern;
An input operation unit configured to input coping information for coping with the abnormal pattern, which is stored in the storage unit in association with the abnormal pattern,
A determination unit that determines whether the pattern of the weight value change of the inspected article to be weighed is the abnormal pattern,
When the determination information is determined to be the abnormal pattern, when the response information associated with the abnormal pattern is stored in the storage unit, a notification unit that can report the response information. Prepared,
The abnormal pattern is a pattern of a change in the weight value of the article to be inspected, which is caused by a failure of a device at a preceding stage disposed on the upstream side in the transport direction of the article to be inspected from the weight sorter,
The input operation unit is capable of inputting the type of the preceding device, and the response information is response information corresponding to the type of the preceding device.

  Since the abnormality occurrence pattern is caused by a malfunction of the preceding device, according to this embodiment, by inputting the type of the preceding device by the input operation unit, when the abnormal pattern occurs, the abnormality of the preceding device is prevented. It is possible to notify appropriate countermeasure information according to the type.

( 4 ) In another embodiment of the weight sorter of the present invention, the storage unit stores in advance a pattern of a weight value change within the predetermined weight range as a warning pattern to be warned before an abnormality occurs. The input operation unit is for inputting warning handling information for dealing with the warning pattern stored in the storage unit in association with the warning pattern, and wherein the determination unit is configured to The pattern of the change in the weight value of the inspected article is to determine whether or not the pattern is the warning pattern. If the determining unit determines that the pattern is the warning pattern, the warning is issued. When the warning handling information associated with the pattern is stored in the storage unit, the warning handling information can be notified.

  According to this embodiment, a pattern of a weight value change within a predetermined weight range that is not abnormal, but causes an abnormality if left as it is, is stored in the storage unit in advance as a warning pattern to be warned before the occurrence of the abnormality. If the determination unit determines that the pattern of the change in the weight value of the inspected article to be measured is a warning pattern, that is, if a warning should be issued, a warning countermeasure for addressing the warning pattern is issued. When the information is stored in the storage unit, the notification unit can notify the warning handling information, so the worker, based on the notified warning handling information, before the abnormality occurs, Appropriate measures can be taken.

  According to the present invention, the pattern of the weight value change outside the predetermined weight range that is selected as a defective product is stored in advance in the storage unit as an abnormal pattern to be reported as abnormal, and the inspected product is measured by the determining unit. When it is determined that the pattern of the weight value change is an abnormal pattern, that is, when an abnormality has occurred, a notification is issued when the storage unit stores information on how to deal with the abnormal pattern. The department can report the response information, so that the worker performing maintenance or the like can take appropriate measures based on the reported response information, When a problem occurs, it is easy to deal with it.

  When the handling information is not stored in the storage unit, the handling information cannot be notified even if an abnormal pattern occurs, and the worker cannot take an appropriate measure based on the handling information.

  In this case, when the worker can identify the cause of the abnormality and take appropriate measures to prevent the abnormality from occurring, the operator can use the input operation as response information to deal with the abnormality pattern. The user can operate the unit to input and store it in the storage unit.

  Therefore, after that, when the same abnormal pattern occurs due to the same cause, since the coping information is stored in the storage unit, the coping information can be notified, and the worker can notify the coping information to be notified. Based on this, it can be easily dealt with.

  In this way, even if the response information is not stored in the storage unit at first, when an abnormal pattern occurs and the cause is specified and appropriate measures are taken, the appropriate measures are stored in the storage unit as the response information. Since the information can be stored, the coping information can be increased as the weight sorter is used, and coping with the occurrence of the abnormal pattern is further facilitated.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a production line including a weight sorter according to an embodiment of the present invention. This production line is a system for weighing and packing articles and inspecting and sorting.

  The system includes a combination weigher 1 that weighs articles (not shown) and discharges articles in an appropriate weight range, a packaging machine 2 that packages the articles discharged from the combination weigher 1, and a conveyer that is unloaded from the packaging machine 2. A metal detector 4 for inspecting whether or not metal is mixed in the packaged inspected article 3; a weight sorter 5 for inspecting whether the weight of the inspected article 3 is within a predetermined weight range; A sorting device 6 for sorting the inspection articles 3 into non-defective products and defective products is provided. The sorting device 6 includes a sorting conveyor 7 that transports the articles 3 to be inspected, and a sorting arm 8 that sorts the articles 3 to be inspected on the sorting conveyor 7.

  The combination weigher 1 is supplied with articles from a supply device (not shown) to a dispersion feeder 9 at the upper center thereof, and the supplied articles are dispersed and conveyed by the dispersion feeder 9 to a plurality of linear feeders 10 therearound. The articles conveyed to the plurality of linear feeders 10 are conveyed linearly and supplied to the plurality of supply hoppers 11, respectively, and further supplied to the plurality of weighing hoppers 12 therebelow. The weight of the article supplied to each weighing hopper 12 is detected by a weight sensor 14 such as a load cell housed in the center base 13, and a combination calculation for selecting a combination of the weighing hoppers 12 having an appropriate weight range is performed. . The articles are discharged from the weighing hoppers 12 of the appropriate combination selected by the combination calculation, and put into the packaging machine 2 via the collecting chute 15.

  The articles are supplied from the supply hopper 11 to the empty weighing hopper 12 after the articles are discharged. Further, the empty supply hopper 11 is supplied with articles from the linear feeder 10 above the empty supply hopper 11, and is further supplied with articles from the dispersion feeder 9 to the linear feeder 10.

  The packaging machine 2 wraps the loaded articles in an appropriate weight range with a packaging material and carries them out. The package conveyed from the packaging machine 2 is conveyed by the conveyor 16 to the infeed conveyor 17 of the weight sorter 5 as the article 3 to be inspected.

  The metal detector 4 is installed on the infeed conveyor 17. The metal detector 4 is disposed, for example, so that the feeding conveyor 17 penetrates a hollow portion of the detection coil, and the detection coil has a transmission coil and two reception coils wound in a substantially rectangular shape. It has a known configuration housed in a state. When a high-frequency current is applied to the transmission coil, the metal detector 4 takes out the difference between the voltages induced in the two reception coils as an output signal, and based on the output signal, the metal is mixed into the article 3 to be inspected. It is determined whether or not metal is mixed, and if a metal is mixed, a detection signal is output to a control unit 18 of the weight sorter 5 described later.

  The weight sorter 5 includes the feed conveyor 17, the weighing conveyor 19, a weight sensor 20 such as a load cell that detects the weight of the article 3 to be inspected on the weighing conveyor 19, a control device 21 that controls each unit, and an operation setting display. A vessel 22 is provided.

  The feed conveyor 17, the weighing conveyor 19, and the sorting conveyor 7 are driven by drive motors (not shown).

  The weight sorter 5 sends the inspected articles 3 one by one to the weighing conveyor 19 by the infeed conveyor 17, measures the weight of the inspected articles 3 on the weighing conveyor 19, and moves the inspected articles 3 within a predetermined weight range. Is determined to be a non-defective product or a defective product outside a predetermined weight range.

  The control device 21 includes an A / D conversion unit 23 that converts an analog load signal from the weight sensor 20 into a digital load signal, the control unit 18 including, for example, a microcomputer, and the conveyors 17, 19, and 7. And a distribution arm drive circuit 25 for driving the distribution arm 8 of the distribution device 6. The control unit 18 includes a CPU and a storage unit 27 including a RAM, a ROM, and the like. The storage unit 27 includes a program memory for storing a control program, a data memory for storing data necessary for calculation, data set by operating the operation setting display 22, and other memories.

  The control section 18 is provided with a detection output of an article detection sensor 26 composed of a photoelectric sensor or the like that detects the article 3 to be inspected immediately before being sent to the weighing conveyor 19. Further, the detection signal from the metal detector 4 is given as described above.

  The operation setting display 22 is, for example, a touch panel type. By touching a key displayed on the display screen, the operation setting display 22 displays start / stop of the operation of the weight sorter 5 and information on coping with an abnormal pattern described later. It has a function as an input operation unit for inputting. Further, the operation setting display 22 has a function as a notification unit that displays a display of a driving result, coping information, and the like.

  The control unit 18 controls the operation of the weight sorter 5 according to a control program stored in the memory of the storage unit 27. The controller 18 calculates the weight value of the inspected article 3 on the weighing conveyor 19 based on the digital load signal from the A / D converter 23, and calculates the weight value of the inspected article 3 as a predetermined weight. It is determined whether it is a non-defective product or a defective product depending on whether or not it is within the range.

  The control unit 18 sets the detection output of the article detection sensor 26 that detects the carry-in of the article 3 to the weighing conveyor 19 as a predetermined reference time point, acquires the weight value of the article 3 to be inspected, and determines whether the article is good or bad. Do.

  If the result of the determination is that the defective product is not a non-defective product, that is, a defective product, the control unit 18 transmits a distribution command to the distribution arm drive circuit unit so that the defective product can be distributed when the defective product reaches the distribution position of the distribution conveyor 6. 25. In this way, when the defective product reaches the distribution position on the distribution conveyor 7, the distribution device 6 removes the defective product out of the transport line by the distribution arm 8 and distributes the defective product.

  Further, when a detection signal indicating the inspected article 3 containing metal is given from the metal detector 4, it is determined to be defective and is similarly removed outside the transport line by the distribution arm 8 of the distribution device 6. And sort.

  When the inspected article 3 is a non-defective product, there is no necessity of distribution, so that the distribution command is not output to the distribution arm drive circuit unit 25, and the non-defective product is conveyed downstream without being distributed by the distribution device 6.

  The above configuration is basically the same as the conventional example.

  The weight sorter 5 of this embodiment is a device at the upstream stage which is a device on the upstream side of the weight sorter 5 in the transport direction of the inspected article 3, specifically, the combination weigher 1, the packaging machine 2, and the metal detector In the case where various troubles occur in step 4, the following is performed so that the troubles can be easily dealt with.

  As described above, when various problems occur in the preceding apparatus, the weight sorter 5 may have an abnormality in which many of the inspected articles 3 are sorted as defective.

  Therefore, a pattern of a change in weight value outside the predetermined weight range is stored in the storage unit 27 of the control unit 18 as an abnormal pattern to be reported as abnormal. It is preferable to store a plurality of weight value change patterns outside the predetermined weight range to be stored as abnormal patterns.

  As the weight value change pattern outside the predetermined weight range, various weight value change patterns to be regarded as abnormal can be adopted. For example, various weight value change patterns can be regarded as abnormal patterns based on the frequency of defective products such as the continuous number of defective products or the percentage of defective products with respect to the whole, or the weight value range of defective products. Furthermore, an abnormal pattern can be formed by combining the frequency of occurrence of defective products and the weight value range of defective products.

  As an abnormal pattern based on the weight range of the defective product, for example, all of the inspected articles 3 selected as defective products by the weight sorter 5 are defective products of “insufficient” less than the lower limit weight value that defines the predetermined weight range. An abnormal pattern, an abnormal pattern in which all of the inspected articles 3 selected as defective products are “excessive” defective products exceeding an upper limit weight value defining a predetermined weight range, or an inspected product selected as defective products An abnormal pattern in which all of the articles 3 are extremely out of the predetermined weight range and extremely small, and are extremely “insufficient” (hereinafter referred to as “super-insufficient”), and all of the inspected articles 3 that are selected as defectives have the predetermined weight. There is an abnormal pattern such as an extreme "excess amount" (hereinafter referred to as "excess amount") which is extremely large outside the range.

  In addition, as an abnormal pattern based on the frequency of occurrence of defective products, for example, the inspected articles 3 weighed by the weight sorter 5 are continuously selected as defective products by a certain number or more. When the first predetermined number of the test articles 3 is selected and the second predetermined number is defective, the ratio of the second predetermined number to the first predetermined number is equal to or more than the third predetermined number. Such as patterns.

  These abnormal patterns are preferably stored in the storage unit 27 of the control unit 18 in advance by the manufacturer, but may be input by the user and stored in the storage unit 27. Partly, for example, the above-mentioned fixed number in an abnormal pattern which is continuously selected as a defective product by a certain number or more, or when the first predetermined number of inspected articles 3 are selected by the weight sorter 5, the second When the predetermined number is defective, the user inputs a numerical value such as the third predetermined number in an abnormal pattern in which the ratio of the second predetermined number to the first predetermined number is greater than or equal to a third predetermined number. You may make it memorize | store in the memory | storage part 27.

  The control unit 18 determines whether or not the weight value change pattern of the inspected article 3 weighed while being conveyed by the weighing conveyor 19 is an abnormal pattern stored in the storage unit 27 in advance, that is, when an abnormality occurs. It has a function as a judging unit 28 for judging whether or not there is.

  The control unit 18 determines that an abnormality has occurred when the determination unit 28 determines that the pattern of the change in the weight value of the inspected article 3 to be measured is the abnormal pattern stored in the storage unit 27 in advance. In some cases, a message to that effect is displayed on the operation setting display 22 as a notification unit to notify the user.

  When a worker performing maintenance or the like recognizing that an abnormality has occurred on the display is able to identify the cause of the failure of the device at the preceding stage of the weight sorter 5 and take appropriate measures to prevent the abnormality from occurring. Then, the operator operates the operation setting display 22 as an input operation unit, and inputs what appropriate measures have been taken for the abnormal pattern reported by the operation as the handling information.

  Thereby, the control unit 18 stores the input coping information in the storage unit 27 in association with the notified abnormal pattern.

  After that, when the determining unit 28 determines that the abnormal pattern in which the coping information is stored in association with the countermeasure information has been generated again, the control unit 18 notifies the operation setting display 22 of the occurrence of the abnormal pattern and associates the abnormal pattern. And display the action information.

  This enables the worker to take a measure based on the measure information displayed on the operation setting display 22, and solves the problem of the device at the preceding stage compared to the first time when the measure information was not displayed. It will be easier.

  If the manufacturer has previously grasped the handling information for the abnormal pattern, the handling information is grasped based on, for example, past data obtained by installing and operating the weight sorter on the production line in the past. If it is possible, the coping information is stored in advance in the storage unit 27 together with the abnormal pattern in association with the abnormal pattern. The coping information for the abnormal pattern is different depending on what kind of device is installed in the preceding stage of the weight sorter 5, that is, the trouble that occurs depending on the type of the former device is different, and the coping information is different. Therefore, it is preferable that individual handling information be stored in the storage unit 27 in advance for each type of the preceding device. Thus, by inputting the type of the device at the preceding stage constituting the production line on the user side, it is possible to notify appropriate countermeasure information according to the type of the device at the preceding stage when an abnormal pattern occurs.

  As described above, the handling information for the abnormal pattern is stored in advance on the manufacturer side, and the control unit 18 determines in the determining unit 28 that the pattern of the change in the weight value of the inspected article 3 to be measured is the abnormal pattern. When it is determined that the handling information associated with the abnormal pattern is stored in the storage unit 27 in advance, the handling information is displayed on the operation setting display 22. The worker can easily take appropriate measures based on the displayed coping information.

  In the above example of the abnormal pattern, for example, the following measures are assumed.

  In other words, if all of the inspected articles 3 selected as defectives by the weight sorter 5 have an abnormal pattern of “insufficient” defectives less than the lower limit weight value that defines the predetermined weight range, the weight sorter 5 5 includes a combination weigher, for example, the discharge gate of the weighing hopper selected for the appropriate combination may not be open / closed due to a failure. When the apparatus is included, there is a possibility that powdery or liquid articles are leaking in the packaging machine or the filling apparatus, and it is necessary to check these.

  In the case where all of the inspected articles 3 selected as defectives are abnormal patterns of “excessive” defectives exceeding an upper limit weight value that defines a predetermined weight range, a combination weigher is included in the preceding apparatus. If it is, there may be a hopper with the discharge gate left open, and if the preceding device includes a filling device, a failure of the filling device is assumed and these need to be checked.

  Further, if all of the inspected articles 3 to be selected as defectives are abnormal patterns in which the number of defectives is extremely short or excessive, if the apparatus at the preceding stage includes a combination weigher, the combination weigher may fail. Is assumed, and if the preceding device includes a filling device, it is assumed that the filling device is defective, and it is necessary to check these.

  As described above, depending on what kind of device is arranged in front of the weight sorter 5, the trouble that occurs is different, and the coping information when the abnormal pattern occurs is also different.

  In this embodiment, prior to the operation operation, the operator operates the operation setting display 22 to set and input the type of the device constituting the production line.

  FIG. 2 is a diagram showing an example of the setting input screen of the operation setting display 22.

  The devices constituting the production line are set and displayed on the four rectangular display keys 29a to 29d at the top of the screen.

  First, the “change / completion” key 30 on the right side of the center of the screen is touch-operated to highlight and display. One of the four display keys 29a to 29d at the top of the screen is touch-operated to highlight and display, and among the device keys 31a to 31e indicating various devices on the left side of the center of the screen, the device key 31a constituting the production line When a touch operation is performed on the display keys 31a to 31e and a touch operation is performed on the "set" key 32 on the right side of the center of the screen, the devices constituting the production line are set and displayed on the highlighted display keys 29a to 29d at the top of the screen.

  To delete a device that has already been set, touch the display key for deleting the device among the four display keys 29a to 29d at the top of the screen to highlight it, and press the "Delete" key on the right side in the center of the screen. 33 is touch-operated.

  The device display screen 34 displaying the device keys 31a to 31e can be scrolled by touching the up key 35 and the down key 36 to display another type of device.

  When the “change / completion” key 30 on the right side of the center of the screen is touched, the setting is completed. When the “return” key 37 on the right side at the bottom of the screen is touched, the screen returns to the screen that called the main setting input screen.

  Next, a more detailed description will be given of a display by the operation setting display 22 when an abnormal pattern occurs after the start of the operation operation, and an operation when the handling information for coping with the abnormal pattern is input to the operation setting display 22. I do.

  FIG. 3 shows an example of weight defect data after the start of the operation and a display screen for notifying the data. On the four display keys 29a to 29d at the top of the screen, a combination weigher, a packaging machine, a metal detector, and a weight sorter constituting a production line are displayed.

  In a rectangular weight change display section 38 at the center of the screen, a change in the weight value of the inspected article 3 measured by the weight sorter 5 is displayed as a reference weight value serving as a reference of a predetermined weight range, a lower limit of the predetermined weight range, and The lower limit weight value and the upper limit weight value that is the upper limit of the predetermined weight range are displayed. Further, a super upper limit weight value and a super lower limit weight value extremely separated from the predetermined weight range are displayed. The super upper limit weight value and the super lower limit weight value are automatically set in accordance with a predetermined weight range set by the user, and how to set them are stored together with the abnormal pattern. It is stored in the unit 27 in advance. The super upper limit value and the super lower limit value may be set by the user.

  In FIG. 3, after detecting the inspected articles 3 having a weight less than the lower limit weight value, the weight values of the ten inspected articles 3 are obtained. As a result, three of the ten inspected articles 3 are defective. The defective products are all defective products having a weight lower than the lower limit weight value. The example in FIG. 3 corresponds to an abnormal pattern in which all of the defective products of the inspected article 3 are “deficient” defective products that are less than the lower limit weight value that defines the predetermined weight range.

  Below the weight change display section 38, there is provided an abnormality display section 39 for displaying the content of the abnormal pattern, and the content of the abnormal pattern, for example, a display such as "The weight defective is only lighter than the lower limit weight value." Is done. On the right side of the weight change display section 38, a message display key 40 for displaying coping information or the like corresponding to the abnormal pattern as an error message is provided.

  By touching the message display key 40, the message screen of FIG. 4 or 5 is displayed and notified.

  FIG. 4 shows an example of a message display screen when the coping information is not stored in the storage unit 27 of the control unit 18.

  An abnormal display section 39 for displaying the contents of the abnormal pattern is provided, and displays the contents of the abnormal pattern, for example, such as "the weight defective is only lighter than the lower limit weight value."

  Below the abnormality display section 39, an information display section 41 for displaying a message of coping information and the like is provided. In the example of FIG. 4, since no coping information is stored, “No data” is displayed. Further, in the absence of coping information, the cause of the abnormality is identified, and appropriate measures are taken to determine the cause of the preceding device. When the problem can be solved, that is, when the problem is solved, the weight error message No. corresponding to the abnormal pattern is obtained. X, a message prompting the user to input as a measure information what action was taken to solve the problem, for example, "If the problem is solved, the data is written in the weight error message No. X. Please enter. "Is displayed.

  FIG. 5 shows an example of a message display screen when the handling information is stored in the storage unit 27 of the control unit 18.

  The information display unit 41 displays a weight failure error message No. identifying the abnormal pattern. Along with the X, the corresponding information, for example, "Please check the operation failure of the discharge gate of the weighing hopper of the combination weigher" is displayed.

  In this way, a worker who performs maintenance or the like checks the operation failure of the discharge gate of the weighing hopper of the combination weigher according to the handling information, and adjusts the weighing hopper so that the weighing hopper operates normally if the operation is not normal. . In this case, if the worker makes an adjustment or the like different from the countermeasure information, the operator corrects or adds the countermeasure information as described later.

  As another embodiment of the present invention, a message such as coping information may be displayed without touching the message display key 40. For example, the message may be displayed together with the weight failure data display screen of FIG. You may do so.

  As shown in FIG. 4 described above, in a state where the coping information is not stored in the storage unit 27 of the control unit 18 and there is no coping information, the worker specifies the cause of the abnormality, takes appropriate measures, and FIG. 6 shows an example of a screen for inputting coping information when the problem of the device can be solved, that is, when the problem is solved.

  In the input screen of FIG. 6, the error message No. of the weight failure corresponding to the abnormal pattern is displayed. Message No. X is displayed. A display unit 42 is provided, and a worker who has solved the problem operates the up key 43 and the down key 44 to display the error message No. designated in FIG. Is displayed. The operator operates a key (not shown) in the key input area 46 to input the coping information as a message on the Japanese input screen 45 displayed below the pop-up. The input coping information is information indicating what measures have been taken to solve the problem. The coping information includes the cause of the occurrence of the abnormal pattern specified by the operator, the type of the article 3 to be inspected. And the date and time when the abnormal pattern occurred.

  As a result, the input coping information corresponds to the error message No. corresponding to the abnormal pattern. It is stored in the storage unit 27 of the control unit 18 in association with the X abnormal pattern.

  Therefore, when the same abnormal pattern occurs thereafter, the message "Check the operation of the discharge gate of the weighing hopper of the combination weigher in the combination weigher" in the information display section 41 in FIG. The message entered on the input screen is displayed as the action information.

  Next, based on the flowchart, the processing of detecting the pattern of the change in the weight value, determining whether or not the pattern is an abnormal pattern, and displaying the coping information will be described in further detail.

  FIG. 7 is a flowchart showing the overall processing of the weight sorter 5.

  First, various settings and operation parameters are set (step S1), and it is determined whether or not the operation is turned on (step S2). When the operation is turned on, normal operation processing is performed (step S3). Is stored (step S4), the weighing data is displayed (step S5), and a pattern of the change in the weight value of the inspected article 3 weighed while being transported is detected. The pattern detection program is executed (step S6), and it is determined whether or not the operation is turned off (step S7). If the operation is turned off, the process proceeds to step S8, and if not, the process returns to step S3.

  In step S8, the above-mentioned coping information is updated / added, and it is determined whether or not the power is turned off (step S9). When the power is turned off, the power is turned off and the process is terminated. If not, the process returns to step S2.

  In FIG. 7, the operation information is updated / added after the operation is turned off. However, the update / addition of the operation information may be performed during the operation. In step S4 of FIG. 7, not only the measured weight value (measured value) of the inspected article 3 but also data such as the type, date and time of the inspected article 3, and the elapsed time from the start of production are stored. For example, if necessary, it may be displayed together with, for example, the weight data shown in FIG. Thus, the type, time, and the like when the abnormal pattern occurs can be grasped, and when the response information is input, data on these types, time, and the like may be included in the response information as described above. .

  FIG. 8 is a flowchart showing an example of the processing of the pattern detection program for detecting the pattern of the change in the weight value of the inspected article 3 in step S6 in FIG.

  In FIG. 8, when a defective product whose weight value is out of a predetermined weight range that is equal to or greater than the lower limit weight value and equal to or less than the upper limit weight value occurs in the inspected article 3 to be measured, the pattern detection flag is set and the weight is measured. The number of inspected articles 3 is counted by various counters built in the control unit 18 according to the range of the weight value of the inspected article 3. If the weight value of the inspected article 3 is significantly deviated from the lower limit weight value and is on the minus side, the weight is counted by the super shortage counter. Similarly, counting is performed by a shortage counter, an excess amount counter, and an excess amount counter according to which weight range the weight value of the inspected article 3 to be weighed belongs to. When a defective product is generated and the pattern detection flag is set as described above, the inspected articles 3 carried in thereafter are counted a predetermined number of times, for example, 10 times by the various counters according to the weight value. I do. The predetermined number of times is counted by a pattern detection counter.

  Specifically, as shown in FIG. 8, it is determined whether or not the pattern detection flag is ON (step S10). If the flag is ON, the process proceeds to step S14. If not, the process proceeds to step S11. Move on to

  In step S11, it is determined whether or not the measured weight value (measured value) kn of the inspected article 3 is in a predetermined weight range not less than a lower limit weight value and not more than an upper limit weight value. That is, if the product is good, the process is terminated. If the product is not in the predetermined weight range, it is determined that the product is defective. The middle flag is turned on, and the process proceeds to step S14 (step S13).

  In step S14, it is determined whether the measured weight value kn of the inspected article 3 is extremely small as compared with the lower limit weight value, that is, whether or not the weight is too short. The count value of the shortage counter is incremented and the process proceeds to step S16 (step S15). When the measured value is not excessively short, the measured weight value of the inspected article 3 is not extremely small as compared with the lower limit weight value. It is determined whether the value is less than the value (Step S20). If the value is insufficient, the count value of the lack counter is incremented and the process proceeds to Step S16 (Step S21). If not, the process proceeds to Step S22.

  In step S22, it is determined whether the measured weight value kn of the inspected article 3 is extremely large as compared with the upper limit weight value, that is, whether or not the excess amount is exceeded. The count value of the quantity counter is incremented, and the process proceeds to step S16 (step S23). If the quantity is not an excess, the measured weight value kn of the inspected article 3 is not extremely large as compared with the upper limit weight value. It is determined whether or not the excess amount exceeds the weight value (step S24). If the excess amount is exceeded, the count value of the excess amount counter is incremented and the process proceeds to step S16 (step S25). If not, the process proceeds to step S16.

  In step S16, the count value of the pattern detection counter is incremented, and the process proceeds to step S17. In step S17, it is determined whether the count value of the pattern detection counter has reached a predetermined value, for example, 10 times. After the defective flag has been set and the pattern detection flag has been set, the process proceeds to step S18 assuming that the weighing of the inspected articles 3 for the predetermined number of times has been completed. If the weighing has not reached the predetermined value, the process ends. In step S18, a process of determining whether the detected pattern of the weight value change of the inspected article 3 is an abnormal pattern, a process of displaying an error message when the detected pattern is an abnormal pattern, and turning off the pattern detection flag are turned off. Then, the process ends (step S19).

  FIGS. 9 and 10 are flowcharts showing an example of the process of determining an abnormal pattern and displaying an error message in step S18 in FIG.

  As shown in FIG. 9, the count value of the pattern detection counter (pattern detection) is obtained by adding the count value of the super shortage counter (the number of super shortage counters) and the count value of the excess amount counter (the number of excess counters). It is determined whether or not the value obtained by dividing by (counter number) and multiplying by 100 is equal to or greater than a predetermined number, that is, whether or not the following equation (1) holds (step S30).

[(Count value of super shortage counter + count value of excess amount counter) / (count value of pattern detection counter)] × 100 (%) ≧ predetermined number (%) (1)
In the equation (1), the ratio (%) of the number of defective products obtained by adding the super-defective defective products and the excess defective products to the predetermined number of times counted by the pattern detection counter is the predetermined number (%). This indicates that this is the case.

  That is, after detecting a defective product, when the inspected product 3 is weighed a predetermined number of times counted by the pattern detection counter, for example, 10 times, the super-deficient and excess defective products occupying the 10 times are added. This indicates that the ratio (%) of the number of defective products is equal to or more than a predetermined number (%).

  Therefore, if this formula (1) is satisfied, there will be many super-deficient defective products and excessive defective products that greatly deviate from the predetermined weight range. Is an error message No. to be described later, depending on what ratio is. 1 to No. It is determined which of the four abnormal patterns corresponding to No. 4 is the abnormal pattern.

  When the above equation (1) holds, the process proceeds to step S31, and when the above equation (1) does not hold, the process proceeds to step S41 in FIG.

  In step S41 of FIG. 10, the count value of the super shortage counter (the number of super shortage counters), the count value of the shortage counter (the number of shortage counters), the count value of the excess amount counter (the number of excess counters), and the total value of the excess amount counter are calculated. Whether the value obtained by dividing the addition count value obtained by adding the numerical value (excess amount counter number) by the count value of the pattern detection counter (number of pattern detection counters) and multiplying by 100 is equal to or greater than a predetermined number, It is determined whether the following equation (2) is satisfied.

[(Count value of super shortage counter + count value of shortage counter + count value of excess amount counter + count value of excess amount counter) / (count value of pattern detection counter)] × 100 (%) ≧ predetermined number (%)・ ・ (2)
The formula (2) is a ratio of the number of defective products obtained by adding the super-defective defective product, the insufficient defective product, the excessive defective product, and the excessive defective product to the predetermined number counted by the pattern detection counter ( %) Is equal to or more than a predetermined number (%).

  In other words, when the inspected article 3 is weighed a predetermined number of times counted by the pattern detection counter after detecting a defective product, for example, 10 times, the shortage, the shortage, the excessive amount, and the excess amount occupy 10 times. This indicates that the ratio (%) of the number of defective products obtained by adding the non-defective products is equal to or more than a predetermined number (%).

  Therefore, if this equation (2) is satisfied, there will be many defective products. In this case, an error described below will occur depending on the proportion of defective products with a super shortage, a shortage, an excess amount, and an excess amount. Message No. 5-No. It is determined which of the four abnormal patterns corresponding to No. 8 is the abnormal pattern.

  When the above equation (2) is satisfied, the process proceeds to step S42, and when the above equation (2) is not satisfied, it is determined that the pattern is not an abnormal pattern, and the process ends.

  In step S31 of FIG. 9, it is determined whether the defective product is only a super-defective defective product. If the defective product is only a super-defective defective product, it is determined that the defective product is the first abnormal pattern. Error message No. corresponding to the first abnormal pattern. 1 is set, and the routine goes to Step S33 (Step S32).

  If it is determined in step S31 that the defective product is not only a super-defective defective product, the process proceeds to step S35, where it is determined whether the defective product is only an excess defective product. In some cases, it is determined that the pattern is the second abnormal pattern, and the error message No. corresponding to the second abnormal pattern is determined. 2 is set, and the routine goes to Step S33 (Step S36).

  If it is determined in step S35 that the defective product is not only the excess defective product, the process proceeds to step S37, in which it is determined whether the number of super-defective defective products is greater than the number of excess defective products. If the number of non-defective products is larger than the number of excess defective products, it is determined that the pattern is the third abnormal pattern, and the error message No. corresponding to the third abnormal pattern is determined. 3 is set and the process moves to step S33 (step S38).

  In step S37, when the number of super-deficient defective products is not larger than the number of defective products in excess amount, it is determined to be the fourth abnormal pattern, and the error message No. corresponding to the fourth abnormal pattern is determined. 4 is set, and the routine goes to Step S33 (Step S).

  In step S42 of FIG. 10, it is determined whether the defective product is only a super-deficient or insufficient defective product. If the defective product is only a super-deficient or insufficient defective product, a fifth abnormal pattern is used. It is determined that there is an error message No. corresponding to the fifth abnormal pattern. 5 is set and the process proceeds to step S33 (step S43). If the defective products are not only super-deficient or insufficient defective products, the process proceeds to step S44. In step S44, it is determined whether or not the defective product is only the excess and excess defective products. If the defective product is only the excess and excessive defective products, it is determined that the defective pattern is the sixth abnormal pattern. And the error message No. corresponding to the sixth abnormal pattern. 6 is set and the process proceeds to step S33 (step S45). If the defective product is not only an excess amount and an excessive amount of defective product, the process proceeds to step S46.

  In step S46, it is determined whether or not the number of insufficient defective products is larger than the number of excessive defective products. When the number of insufficient defective products is larger than the number of excessive defective products, the seventh abnormal pattern is determined. And the error message No. corresponding to the seventh abnormal pattern. 7 is set, and the process proceeds to step S33 (step S47). If the number of insufficient defective products is not larger than the number of excessive defective products, it is determined to be the eighth abnormal pattern and the eighth abnormal pattern is determined. Error message No. corresponding to. 8 is set, and the routine goes to Step S33 (Step S48).

  In step S33 of FIG. 9, the error message No. set in accordance with the determined abnormal pattern. It is determined whether or not there is data to be displayed. That is, it is determined whether or not the coping information associated with the determined abnormal pattern is stored in the storage unit 27 of the control unit 18. When the coping information is stored, an error is generated according to the operation of the worker. The response information is displayed and notified as a message (step S34). Based on the response information displayed as the error message, the worker adjusts and repairs the equipment that composes the production line to resolve the problem, but the adjustment differs from the content of the response information displayed as the error message.・ Repair may be performed. Therefore, in step S34, if necessary, a message prompting the user to correct and add the coping information, for example, "Please correct and add data if necessary" is displayed, and the process ends.

  In step S33, when the coping information associated with the determined abnormal pattern is not stored in the storage unit 27 of the control unit 18, there is no coping information data, and the operator himself specifies the cause of the abnormality. When appropriate measures are taken to solve the problem of the preceding device, that is, when the problem is solved, a message that prompts the user to input the appropriate action as data for handling, for example, "No data. If resolved, input data. "Is displayed and the process ends (step S40).

  Although not shown in the flowcharts of FIGS. 9 and 10, when the inspected articles 3 having a weight defect frequently occur and the above error messages are displayed, the weight sorter 5 is connected to a communication line (not shown). The production line is stopped by sending a signal to each device such as the combination weigher 1 constituting the production line, and the operator adjusts and repairs the device constituting the production line.

  According to the present embodiment, the pattern of the weight value change outside the predetermined weight range is stored in advance in the storage unit 27 as an abnormal pattern to be notified of the abnormality, and the determination unit 28 determines the When it is determined that the pattern of the weight value change is an abnormal pattern, when the countermeasure information for coping with the abnormal pattern is stored in the storage unit 27, the countermeasure information is displayed on the operation setting display 22. Can be displayed, so that a worker performing maintenance or the like can take appropriate measures based on the displayed countermeasure information, and can easily cope with the occurrence of an abnormality.

  Further, even if the handling information is not stored in the storage unit 27, if the operator can identify the cause of the abnormality and take appropriate measures, the appropriate measures are displayed on the operation setting display 22. Can be input and stored in the storage unit 27.

  Therefore, if a similar abnormal pattern occurs for the same reason thereafter, the handling information stored in the storage unit 27 can be displayed on the operation setting display 22. Based on the information, it can be easily dealt with.

  As described above, even if the handling information is not initially stored in the storage unit 27, when an abnormal pattern occurs and the cause is specified and appropriate measures are taken, the appropriate action is taken as the handling information. 27, and furthermore, the handling information can be modified, so that as the weight sorter 5 is used, the handling information can be updated to one suitable for the actual production line, The action to be taken when an abnormal pattern occurs becomes more appropriate.

  The worker adjusts the malfunctioning device based on the handling information displayed on the operation setting display 22. Therefore, even if the worker is different, the worker adjusts the device in the same manner based on the handling information. It can be performed.

  The abnormal pattern pre-stored in the storage unit 27 can be added or corrected by upgrading the software. Therefore, the abnormal pattern and the handling information for coping with the abnormal pattern can also be added and corrected. Even if an abnormality occurs due to various inconveniences, appropriate measures can be taken at an early stage. Accordingly, when the production line must be stopped due to a failure of the device at the preceding stage of the weight sorter 5, the production line can be operated with appropriate measures at an early stage, and the production loss time can be reduced. be able to.

  In the above embodiment, when it is determined that the pattern of the change in the weight value of the inspected article 3 to be measured is an abnormal pattern out of the predetermined weight range, the malfunction of the preceding device causing the occurrence of the abnormal pattern is determined. However, as another embodiment of the present invention, in addition to the configuration of the above-described embodiment, when an abnormality is assumed to occur, a warning is issued, and a warning countermeasure for coping with the warning is issued. Information may be notified.

  That is, when the weight value of the inspected article 3 to be weighed is within the predetermined weight range, if the state is continued, a large number of defective products out of the predetermined weight range are generated, that is, there is a possibility that an abnormality may occur. Then, a warning is issued, and warning handling information for improving the state is reported.

  For example, a warning can be given to a state where good products slightly larger than the lower limit weight value or slightly smaller than the upper limit weight value continue, and warning handling information for improving the state can be notified. It is to be.

  In this embodiment, a pattern of a weight value change within a predetermined weight range is stored in the storage unit 27 of the control unit 18 in advance as a warning pattern to be warned before the occurrence of an abnormality. Also, by operating the operation setting display 22 as an input operation unit, warning handling information for dealing with the warning pattern is input in association with the warning pattern and stored in the storage unit 27. The determination unit 28 determines whether the pattern of the change in the weight value of the inspected article 3 to be measured is a warning pattern, and when it is determined that the pattern is a warning pattern, a warning associated with the warning pattern When the handling information is stored in the storage unit 27, the warning handling information is displayed on the operation setting display 22 to notify the user.

  FIG. 11 is a view showing an example of a weight data warning screen according to this embodiment, which corresponds to FIG. 3 of the above embodiment, and corresponding parts are denoted by the same reference numerals.

  In a rectangular weight change display section 38a at the center of the screen, a change in the weight value of the inspected article 3 measured by the weight sorter 5 indicates a reference weight value serving as a reference of a predetermined weight range, a lower limit of the predetermined weight range, and The lower limit weight value and the upper limit weight value that is the upper limit of the predetermined weight range are displayed. Further, a warning lower limit weight value and a warning upper limit weight value are displayed in a predetermined weight range. The warning lower limit weight value and the warning upper limit weight value are automatically set when a predetermined weight range is set by the user, and how to set them together with the warning pattern is stored. It is stored in the unit 27 in advance. The warning lower limit weight value and the warning upper limit weight value may be set by the user.

  In FIG. 11, after detecting the non-defective inspected articles 3 having a weight less than the warning lower limit weight value, the weight values of ten non-defective inspected articles 3 are obtained. As a result, the ten non-defective inspected articles 3 are obtained. Indicate that all of the weight values are good products with a weight lower than the reference weight value. The example of FIG. 11 shows a warning pattern in which all of the weight values of non-defective inspected articles 3 are smaller than the reference weight value (minus side).

  Below the weight change display section 38a, a warning display section 39a for displaying the content of the warning pattern is displayed, and the content of the warning pattern, for example, a display such as "the weight value is on the minus side with respect to the reference weight value." Is done. On the right side of the weight change display section 38a, a message display key 40a for displaying warning handling information or the like corresponding to the warning pattern as an error message is provided.

  By touching the message display key 40a, a screen corresponding to FIG. 4 or FIG. 5 of the above embodiment is displayed.

  FIG. 12 is a flowchart illustrating an example of processing of a pattern detection program for detecting a pattern of a change in weight value of the inspected article 3 to be measured, and is a flowchart corresponding to FIG.

  First, it is determined whether or not the pattern detection flag is ON (step S50). If the flag is ON, the process proceeds to step S54, and if not, the process proceeds to step S51.

  In step S51, it is determined whether or not the measured weight value kn of the inspected product 3 is in a weight range that does not require a warning that is not less than the warning lower limit weight value and is not more than the warning upper limit weight value. If not, the warning is terminated.If the warning is not in the unnecessary weight range, a warning shortage counter for counting non-defective products below the lower warning weight value, a warning excess amount counter for counting non-defective products exceeding the warning upper weight value, a pattern for counting a predetermined number of times. The detection counter is initialized (step S52), the flag during pattern detection is turned on, and the process proceeds to step S54 (step S53).

  In step S54, it is determined whether or not the weighed value kn of the inspected article 3 is a non-defective item less than the lower warning lower limit value. The value is incremented and the process moves to step S56 (step S55).

  In step S60, it is determined whether or not the weighed value kn of the inspected article 3 is a non-defective product exceeding the warning upper limit value. If the measured weight value kn is a non-defective product exceeding the warning upper limit value, the count value of the warning excess amount counter is incremented. Then, the process proceeds to step S56 (step S61). If the product is not a non-defective product exceeding the warning upper limit, the process proceeds to step S56.

  In step S56, the pattern detection counter is incremented, and it is determined whether or not the count value of the pattern detection counter has reached a predetermined value, for example, 10 times (step S57). When the count value has reached the predetermined value, the process proceeds to step S58. If it is not the predetermined value, the process ends. In step S58, a determination process of determining whether the detected pattern of the change in the weight value of the inspected article 3 is a warning pattern and a display process of a warning message when the detected pattern is a warning pattern are performed. Is turned off and the process is terminated (step S59).

  FIG. 13 is a flowchart showing an example of the process of determining a warning pattern and displaying a warning message in step S58 of FIG.

  First, the counted value obtained by adding the count value of the warning shortage counter (the number of warning excess counters) and the count value of the warning excess amount counter (the number of warning excess counters) is divided by the count value of the pattern detection counter (the number of pattern detection counters). Then, it is determined whether or not the value multiplied by 100 is equal to or more than a predetermined number, that is, whether or not the following equation (3) is satisfied (step S70).

[(Count value of warning shortage counter + count value of warning excess counter) / (count value of pattern detection counter)] × 100 (%) ≧ predetermined number (%) (3)
In this equation (3), the ratio (%) of the number of non-defective products obtained by adding the non-defective products with insufficient warning and the non-defective products with excessive warning to the predetermined number counted by the pattern detection counter is equal to or more than the predetermined number (%). It is shown that.

  When the above equation (3) is satisfied, the process proceeds to step S71, and when the above equation (3) is not satisfied, it is determined that the pattern is not a warning pattern and the process ends. In step S71, it is determined whether or not there are only non-defective products with insufficient warning. If only non-defective products with insufficient warning are determined, the first warning pattern is determined and the warning message No. corresponding to the first warning pattern is determined. . The value 1 is set and the process proceeds to step S73 (step S72). In step S75, it is determined whether there is only a non-defective product with an excessive amount of warning. If only a non-defective product with an excessive warning amount is determined, a second warning pattern is determined, and a warning message No. corresponding to the second warning pattern is determined. . The value 2 is set, and the process proceeds to step S73 (step S76).

  In step S78, it is determined whether or not the number of non-defective products with insufficient warning is greater than the number of non-defective products with excess warning. If the number of non-defective products with insufficient warning is greater than the number of non-defective products with excessive warning, the third warning pattern is used. And a warning message No. corresponding to the third warning pattern. 3 is set and the process proceeds to step S73 (step S79). If the number of non-defective products with insufficient warning is not larger than the number of non-defective products with excessive warning, it is determined to be the fourth warning pattern, and the fourth warning pattern is determined. Warning message No. corresponding to 4 is set, and the routine goes to Step S73 (Step S80).

  In step S73, the set warning message No. It is determined whether or not there is warning handling information as display data in the message, and if there is display data, the warning message is displayed. Further, if necessary, a display prompting to correct or add data is displayed. If there is no warning handling information as display data, there is no data, and if the problem is solved, a message prompting the user to input data is displayed and the process ends (step S77).

  Even if it is determined to be a warning pattern and a warning message is displayed, it is not necessary to stop the production line because the inspected article 3 is not a defective product. Without stopping the production line, it is also possible to make adjustments while operating the devices constituting the production line.

  When an abnormal pattern occurs, an error message such as information on handling the abnormal pattern is displayed prior to the warning pattern.

  In each of the above embodiments, the handling information is displayed and notified by the operation setting display 22. However, the handling information is not limited to the display and may be notified by printing or voice.

  In each of the above embodiments, when it is determined that the pattern is an abnormal pattern or a warning pattern, it is displayed and notified by the operation setting display 22, but is notified by a notification sound or voice of a buzzer or the like, or lighting by a display lamp. You may.
