[The problem to be solved by the invention]

In the equipment used to manufacture goods, various abnormalities may occur during the operation of the equipment that require handling by the operator. In order to eliminate the abnormality, it is necessary to explore the location of the abnormality, investigate the cause, and take countermeasures. In such a treatment, it is necessary to repeatedly stop the operation of the equipment during the treatment. Compared with the continuous operation, the assumed quantity (that is, the estimated manufacturing quantity) will be reduced. On the other hand, when the manufacturing capacity (that is, the manufacturing quantity per unit time) is reduced due to an abnormality of the equipment, the recovery of the manufacturing capacity can be expected by the treatment, but an increase in the imagined quantity can be expected. Therefore, the inventors of this case, when deciding whether to deal with the abnormality of the equipment, considered many conditions such as the estimation of the time required for the treatment or the expectation of the amount of recovery of the manufacturing capacity caused by the treatment. Automatically determine which situation is more advantageous and the required system, and conduct repeated discussions.

Also, in the case of manufacturing articles, the deadline and planned quantity are generally set based on the contract with the consignor or own business goals. Therefore, the inventors of this case thought that it would be ideal to design a system that takes into account the deadline or the number of plans in addition to the many conditions mentioned above when automatically determining whether or not to deal with the abnormality of the equipment. By such a design, it can be prevented, for example, that if the equipment continues to operate, the planned number can be reached by the deadline, but because of a misjudgment, the operation of the equipment is stopped and the disposal is performed, which instead leads to failure. On the contrary, it can be prevented that if the equipment abnormality is eliminated, the manufacturing capacity can be restored and the planned quantity can be achieved. However, due to a misjudgment, the abnormal operation is allowed to continue, and the result is not reached.

Furthermore, the inventors of this case also thought that when dealing with equipment abnormalities, it is sometimes very important to judge how much time is left before proceeding to deal with the planned quantity before the deadline. of. With such a design, for example, while the abnormality of one equipment A is being handled, an abnormality also occurs to another equipment B, and it must be handled by the same operator. In this case, should the equipment A continue to be handled? For disposal, the disposal of equipment A should be temporarily interrupted and the disposal of equipment B should be given priority. This can be clearly judged if the remaining time for each treatment can be known. In addition, in the case where the equipment is abnormal in the time zone when the operator is absent, it is also the case to determine whether the operator needs to be called urgently, and the information of the remaining time can be useful.

The present invention is in view of the above-mentioned problem, and its object is to provide a system, method, and computer program that automatically determine the timing of the operator's handling of abnormalities in equipment required to manufacture articles. [Means to solve the problem]

In one aspect, the present invention provides a system for determining the timing of equipment abnormality handling for automatically determining the timing of the handling of abnormalities of equipment required for the manufacture of articles by the operator. The equipment abnormality handling sequence determination system has: an abnormality occurrence rate judging unit, which judges the ratio of the abnormal value of the current state index for each of more than one state index about the equipment, that is, the abnormal occurrence rate, whether the abnormal occurrence rate exceeds that of the current The threshold value determined by the state indicator to establish a connection. The equipment abnormality handling sequence determination system further includes a treatment content determination unit that determines the content of the treatment that the operator should perform when the abnormality occurrence rate determination unit determines that the abnormality occurrence rate exceeds the threshold value, that is, the treatment content. The equipment abnormality handling sequence determination system also has: a comparison unit for the assumed quantity after the treatment and the undisposed quantity, which determines the quantity of items that are estimated to be manufactured by the prescribed time limit if the operator starts the treatment immediately according to the content of the treatment. That is, the assumed quantity after disposal, whether it exceeds the number of items that are estimated to be manufactured by the deadline without disposal, is also the undisposed quantity. The equipment anomaly handling sequence determination system also has: the first post-treatment imagined quantity vs. plan comparison unit, when the post-treatment imagined quantity exceeds the unprocessed imagined quantity in the post-disposal vs. unprocessed imagined quantity comparison part, After judging whether the assumed quantity is exceeded, the quantity of items set as the target to be manufactured by the deadline is the planned quantity. The equipment abnormality handling time sequence determination system also has a handling time sequence determining unit that determines the time sequence at which the operator should start handling, that is, the handling time sequence. The equipment abnormality handling sequence determination system also has an output unit that outputs the handling sequence together with the handling content.

The processing sequence determination unit determines that the processing sequence is determined by the post-processing scenario-to-plan comparison section when the post-processing scenario-prepared volume exceeds the planned volume. The operator must determine the processing sequence based on the post-processing scenario and the plan. The difference in the quantity is calculated within the margin time to start processing. The processing sequence determination unit determines that the post-processing scenario does not exceed the planned number in the first post-processing scenario comparison unit when the scenario number does not exceed the planned volume, and the operator must immediately start the process.

In one embodiment, the equipment abnormality handling sequence determination system also has: a second post-treatment post-treatment scenario-to-plan comparison unit, which determines that the post-treatment scenario volume does not exceed the post-treatment scenario comparison unit. When the imaginary quantity is not processed, it is determined whether the imaginary quantity after the disposal exceeds the planned quantity. In one embodiment, the equipment abnormality handling sequence determination system also has: a post-treatment and non-treatment scenario benefit comparison unit, and the second post-treatment scenario-to-plan comparison unit determines that the post-treatment scenario has exceeded the plan. In the case of quantity, it is judged whether the assumed benefit of the operator in the case of disposing according to the disposal content is the post-disposal post-disposal benefit, and whether it exceeds the pre-determined benefit in the case of no disposal, which is the non-disposal pre-determined benefit. In one embodiment, the disposal sequence decision unit determines that the post-disposition scenario benefit exceeds the non-disposal scenario profit after the disposal in the non-disposal scenario profit comparison unit, and the processing sequence is determined, and the operator must immediately Start disposal.

In one embodiment, the processing content determination unit has: a list storage unit that stores the judgment basis determined for each state index as the judgment basis list of the components and the judgment basis is established as the corresponding operation content. The work content list for the components; and the judgment basis verification department, which is based on the judgment basis in the judgment basis list, and extracts those that meet the current situation. In one embodiment, the processing content determination unit determines the priority for each of the extracted judgment bases when the judgment basis extracted from the verification unit is determined to exist, and at least based on the priority Select one or more judgment basis from the extracted judgment basis, and determine the selected judgment basis as the processing content based on the corresponding work content. In one embodiment, the treatment content determination unit determines all the work content in the work content list to be the treatment content when the judgment basis extracted from the verification unit is determined to be non-existent.

In one embodiment, the processing content determination unit, if the judgment basis extracted from the verification unit is judged to exist, then for each of the extracted judgment basis, it is assumed that the cause of the current judgment basis has been The effect at the time of elimination is based on at least the priority and the effect that has been estimated, and more than one judgment basis is selected from the judgment basis that has been extracted, and the judgment that has been selected is determined based on the corresponding work content Become disposal content.

In one aspect, the present invention provides a method for determining the timing of equipment abnormality handling required to automatically determine the timing of the handling of abnormalities of equipment required for the manufacture of articles by the operator. In addition, the present invention, in one aspect, provides a computer program that can be executed on a computer system that contains commands required for the computer to execute the steps of the method for determining the timing of handling equipment abnormalities. [Effects of the invention]

By using the equipment abnormality processing timing determination system described in one aspect of the present invention, the operator will automatically determine the necessity, content, and timing of the processing of equipment abnormalities required to manufacture items. . At this time, depending on the processing content determined from the state of the equipment, whether the improvement of the manufacturing quantity by the deadline can be expected by the processing, and if the processing is performed, whether the planned quantity can be achieved by the deadline, These judgments will be made. Based on the results of the judgment, it will be decided whether the disposal should be carried out, what should be done, in order to reach the planned quantity before the deadline, how much time is left before the disposal starts, or whether it needs to start immediately Disposal. In one embodiment, the system will also determine whether the improvement of benefits can be expected under the condition of the disposal, and this will be reflected in the decision of whether the disposal is necessary or not.

In one embodiment, the appropriate action content is determined based on the priority of eliminating the cause of the abnormality and the estimated effect when the cause of the abnormality is eliminated.

The following describes the implementation of the system for determining the timing of equipment abnormality handling according to the present invention with reference to the drawings.

FIG. 1 is a block diagram of a schematic configuration of a system 100 for determining an equipment abnormality handling sequence according to an embodiment of the present invention. The equipment abnormality handling sequence determination system 100 is based on the information 151 about the status index of the equipment P, and when it is judged that it is necessary to deal with the abnormality, it outputs the information 152 of the time sequence and the handling content that must be handled from the output unit 130 .

In one embodiment, the equipment abnormality treatment sequence determination system 100 includes: an abnormality occurrence rate determination unit 111, a treatment content determination unit 112, a post-treatment vs. non-treatment scenario comparison unit 113, and a first post-treatment scenario vs. plan The comparison unit 114 and the treatment sequence determination unit 115. In one embodiment, the treatment content determination unit 112 includes a list storage unit 121 storing a judgment basis list 122 and a work content list 123, and a judgment basis verification unit 118. In one embodiment, the equipment abnormality handling sequence determination system 100 further includes a post-treatment scenario-to-plan comparison unit 116 and a post-process vs. non-treatment scenario-based profit comparison unit 117.

FIG. 2 illustrates the configuration of an exemplary computer hardware of the equipment abnormality handling timing determination system 100 according to an embodiment of the present invention. The equipment abnormality handling timing decision system 100 can be used, and has: a central processing unit (CPU), a memory device such as RAM, ROM, and hard disk drive (HDD) that stores various programs or data executed by the central processing unit, A general-purpose computer that connects these devices to each other can be realized. Furthermore, the timing of equipment abnormality handling determines the system 100, and the system 100 can be connected according to needs: a drive device, keyboard or mouse for data input and output between external memory media such as CD-ROM or DVD-ROM, etc. The input device, the output device of CRT, liquid crystal display or printer, etc., the communication interface required for communication with other computers or networks.

FIG. 3 is a diagram illustrating a processing flow 300 executed in order to determine the timing at which an abnormality must be handled in the equipment abnormality handling timing determination system 100 according to the first embodiment of the present invention.

The processing flow 300 starts at step 301. The equipment abnormality handling sequence determination system 100 may also be configured to start the process 300 whenever the information 151 of the status indicator is received from the equipment P. Alternatively, the equipment abnormality handling timing determination system 100 may also be configured to repeatedly start the process 300 in a regular or continuous manner, and each time it is executed, it will obtain status indicators from the equipment P Information 151.

The status index is an index indicating the status of the device P, and can be appropriately determined according to the type of the device P. For example, if the device P is an RTP device, as illustrated in the leftmost column of FIG. 6, "adhesive accuracy", "adhesion of foreign matter", "occurrence of bubbles", and "occurrence of defects and ruptures" can be used as state indicators, respectively. In the RTP method, in the manufacturing process of liquid crystal display devices, etc., from a strip-shaped optical film laminate supported by a plurality of sheet-shaped optical films via an adhesive layer on a strip-shaped release film, only defects are free. The normal sheet-like optical film, together with the adhesive layer, is successively peeled from the release film, and laminated with the rectangular panel through the adhesive layer, thereby continuously manufacturing liquid crystal display devices. The continuous manufacturing system for the liquid crystal display device in this way is different from the previous device that realizes the individual bonding method in which the pre-cut optical film sheet is bonded to the rectangular panel, and is called "continuous bonding" or " RTP (Roll to Panel)" device. "RTP" and "Roll to Panel" are registered trademarks of Nitto Denko Corporation. In this case, the so-called "adhesion accuracy" refers to the state index indicating the error of the actual position of the optical film relative to the target position on the panel when the optical film is attached to the panel. The so-called "adhesion of foreign matter" refers to the The state indicator for detecting the adhesion of foreign matter in the panel laminated with the optical film. The so-called "occurrence of bubbles" refers to the state indicator that the bubbles can be detected in the optical film that has been laminated to the panel. The so-called "defect, "Broken" is an indicator of the state in which defects or cracks can be detected in the panel.

In step 302, for each of the status indicators, it is determined whether the ratio of the current status indicator showing abnormal values, that is, the abnormal occurrence rate, exceeds the threshold determined by establishing a relationship with the current status indicator. Here, the so-called abnormal value can be defined as a value that represents the state of the device P represented by the state index, and is a value that is the main cause of a decrease in manufacturing capacity (that is, the number of manufacturing per unit time). For example, in the case of an RTP device, the so-called "sticking accuracy" is an abnormal value that can be determined as a value where the position error exceeds the predetermined allowable error range. In this case, the panel where the optical film is bonded to the position exceeding the allowable error range is a defective product, which will reduce the yield, which is the main cause of the reduction in manufacturing capacity. In addition, the so-called "attachment of foreign matter" is an abnormal value, which can be determined as the detection of attachment of foreign matter. The abnormal occurrence rate may be based on the nature of the article being manufactured by the equipment P or the state index, and set the ratio of the number of times the state index exhibits an abnormal value, or the number of occurrences of the abnormal value per unit time, etc. If the abnormal occurrence rate exceeds the threshold determined in connection with the current state index (for example, the abnormal value is 5 out of the last 100 times), the process proceeds to step 303. On the other hand, if the occurrence rate of abnormality does not exceed the threshold, it is determined that the treatment is not necessary at the current point, the information 152 of the treatment sequence and the treatment content will not be output, and the process proceeds to step 311.

In step 303, the content of the treatment that the operator should perform, that is, the content of the treatment, is determined. Here, referring to FIG. 4, a specific example of the processing for determining the treatment content will be described. The process 400 of processing content determination starts at step 401. In step 402, from the judgment basis list 122 stored in the list storage unit 121, the judgment basis corresponding to the status indicator and conforming to the current situation is extracted. For example, if the device P is an RTP device and the judgment basis list 620 shown in FIG. 6 is used, if the status index of the abnormal occurrence rate exceeding the threshold is "adhesive accuracy", it will be placed in the judgment basis list 620 in the "recent change" Among the four judgement bases of "parameters", "recently replaced rolls", "feed roller replacement time has approached or exceeded", and "sticking roller replacement time has approached or exceeded", those that meet the status quo will be selected. The status quo is, for example, the recognition based on the information 153 of the treatment input by the operator and the operation other than the treatment, or the information 154 that can be obtained from the equipment P, etc.

Next, in step 403, it is judged whether there is a judgment basis that has been extracted. If it is determined that more than one has been extracted based on the existence of more than one, proceed to step 404. In step 404, for each of the extracted judgment basis, the effect when the reason for the judgment basis has been eliminated is estimated. Then, in step 405, the priority is determined for each of the extracted judgment basis. After that, in step 406, based on the priority and the effect that has been estimated, select more than one judgment basis from the judgment basis that has been extracted, and determine the work content in the corresponding work content list. Become disposal content. For example, in the case of using the judgment basis list 620 and the work content list 630 illustrated in FIG. 6, the judgment basis for the state index of "adhesive accuracy" has been selected if it is "the replacement period of the feed roller is approaching or exceeding", Then the corresponding operation content, that is, "feed roller replacement" is determined to be the disposal content.

On the other hand, in step 403, if the judgment basis that has been extracted is that there is not even one of them, the process proceeds to step 409. In step 409, from the judgment basis list 122, all judgment basis corresponding to the status indicator are selected. Then, the estimation of the effect and the priority of each of the judgment bases are not determined, and the operation contents corresponding to each of the judgment bases are all determined as the processing contents. For example, if the equipment P is an RTP device, and the judgment based on the list 620 and the work content list 630 shown in Figure 6 are used, for the status indicator of "adhesive accuracy", if "parameters have been changed recently" and "reels have been changed recently" Any one of "the replacement time of the feed roller is approaching or exceeding" "the replacement time of the sticking roller is approaching or exceeding" does not meet the status quo, then the corresponding "parameter correction", "parameter adjustment", and "feeding" All of "roller replacement" and "adhesive roller replacement" are determined to be the contents of disposal.

Returning to FIG. 3, in step 304, assuming that the operator immediately starts the treatment in accordance with the treatment content determined in step 303 (that is, the treatment content determination process flow 400), it is presumed that it will be met by the predetermined time limit. The quantity of manufactured items is the assumed quantity after disposal, and the quantity of items estimated to be manufactured by the deadline without disposal, which is the undisposed quantity, will be compared. If it is determined that the assumed number after the treatment does not exceed the assumed number before the treatment, it is determined that the treatment should not be performed, the information 152 of the treatment sequence and the content of the treatment is not output, and the process proceeds to step 311.

On the other hand, in step 304, if it is determined that the post-treatment scenario exceeds the non-treatment scenario, the process proceeds to step 305. In step 305, the assumed quantity after the treatment is compared with the quantity set as the target to be manufactured by the deadline, that is, the planned quantity. In the case where it is determined that the assumed quantity after the treatment exceeds the planned quantity, that is, if the treatment is assumed to start immediately, the planned quantity is expected to be achieved, in step 306, the treatment sequence will be determined as: The operator must start the treatment within the margin time calculated based on the difference between the planned quantity and the planned quantity after the disposal. On the other hand, when it is judged that the imaginary quantity after the disposal does not exceed the planned quantity, that is, even if the disposal is started immediately, it is expected that the planned quantity cannot be achieved, and there is no room for time at all, in step 307 As the processing sequence will be determined, the operator must start the processing immediately. In either case, in step 310, the information 152 of the treatment sequence and the treatment content will be output and notified to the operator. The operator who has been notified of the information 152 of the processing sequence and the content of the processing shall deal with the abnormality of the equipment P, and record the processing and operation information other than the processing.

In step 311, the processing flow 300 ends.

The graphs (1) to (4) of Fig. 5 show four modalities regarding the relationship between the assumed quantity at the time of non-treatment and the assumed quantity after the treatment and the planned quantity. In each graph, the horizontal axis represents time, tc represents current point, and te represents deadline. The vertical axis represents the manufacturing quantity, and the p represents the planned quantity. The solid line portion A on the left side of the current point tc indicates the change in the actual production quantity up to the current point. The solid line B on the right side of the current point tc indicates the transition of the estimated manufacturing quantity without treatment. The height of the solid line B on the time limit te represents the expected quantity when it is not disposed of. The dashed part C indicates the transition of the estimated manufacturing quantity in the process when the process is assumed to start immediately. Since the operation of the equipment P will be stopped during the treatment, no article will be manufactured, so the dashed part C is a horizontal line. The solid-line part D indicates the estimated transition of the manufacturing quantity after the treatment, assuming that the treatment is performed immediately. The height of the solid line part D on the time limit te represents the assumed quantity after disposal.

In the mode of (1), the imaginary quantity after disposal does not exceed the imaginary quantity when not disposed, nor does it reach the planned quantity p. In this case, in step 304, it is determined whether the post-treatment assumed number does not exceed the non-processed assumed number, so the information 152 of the treatment sequence and the content of the treatment will not be output.

In the mode of (2), the imaginary quantity after disposal, although it does not exceed the imaginary quantity at the time of non-disposal, but it reaches the planned quantity p. In this case, as in the modal of (1), it is determined in step 304 whether the post-treatment assumed quantity does not exceed the non-processed pre-determined quantity, so the information 152 of the processing sequence and the content of the processing will not be output . In addition, the mode of (1) and the mode of (2) can be distinguished in the second embodiment of the present invention described later.

In the mode of (3), the imaginary quantity after disposal, although it exceeds the imaginary quantity when not disposed, it does not reach the planned quantity p. In this case, in step 304, it is determined that the post-treatment scenario exceeds the unprocessed scenario, and in step 305, it is determined that the post-processing scenario does not exceed the planned number, so in step 307, it is treated as a treatment The timing will be determined, and the operator must start processing immediately.

In the mode of (4), the post-disposal imaginary quantity is more than the non-disposal imaginary quantity, and the planned quantity p is reached. In this case, in step 304, it is determined that the post-processing scenario exceeds the unprocessed scenario, and in step 305, it is determined that the post-processing scenario exceeds the planned number. Therefore, in step 306, it is treated as a treatment The time sequence will be determined so that the operator must start the treatment within the margin calculated based on the difference between the planned amount and the planned amount after the treatment.

In the mode of (4), as an example, the margin time system can be calculated as follows. The slope of the solid line B (that is, the estimated manufacturing capacity without treatment (that is, the number of production per unit time)) and the slope of the solid line D (that is, the The estimated manufacturing capacity after disposal) is respectively assumed to be constant, so that the slope of the solid line part B is b and the slope of the solid line part D is d. Specifically, b can be regarded as the manufacturing capacity from the most recent point in the past when the abnormality is considered to have occurred to the present, and d is the manufacturing capacity in the stable period before the abnormality, for example, just after the start of manufacturing. Generally speaking, treatment is performed in order to restore manufacturing capacity, so d>b. Also, let the difference between the assumed quantity after the disposal and the planned quantity p be ε. At this time, the margin time can be calculated as ε/(d-b). Assuming that the treatment is started at the end of the surplus time, the expected manufacturing quantity by the deadline te is consistent with the planned quantity p, which can be determined by calculation.

FIG. 7 is a diagram illustrating a processing flow 700 that is executed in order to determine the timing at which the abnormality must be handled in the equipment abnormality handling timing determination system 100 according to the second embodiment of the present invention. The steps of the processing flow 700 are the same as the steps of the processing flow 300 described in the first embodiment, except for step 708 and step 709. Therefore, the second embodiment will be described below with respect to the differences from the first embodiment.

In step 704, if it is determined that the post-treatment scenario does not exceed the unprocessed scenario (for example, in the case of (1) and (2) in Figure 5), then in step 708, the post-processing scenario The number of paintings will be compared. When it is judged that the assumed quantity after the treatment does not exceed the planned quantity (for example, in the case of (1) in Fig. 5), it is judged that the treatment should not be performed, and the information 152 of the treatment sequence and the content of the treatment will not be output, and go to step 711 forward. On the other hand, when it is determined that the post-treatment assumed quantity exceeds the planned quantity (for example, in the case of (2) in FIG. 5), in step 709, the operator is subjected to the treatment in accordance with the treatment content. The imaginary benefit is the imaginary benefit after disposal, and the imaginary benefit without disposal, that is, the imaginary benefit before disposal, will be compared. Here, the so-called benefit can be, for example, the benefit caused by reaching the planned quantity earlier than the deadline, or the benefit caused by the manufacture of more items within the deadline, or the replacement cost of parts due to replacement of parts. The negative benefits involved are calculated by converting the conceivable positive and negative benefits, for example, into amounts or points, and then adding them up. If it is determined that the imaginary benefit after the treatment does not exceed the imaginary benefit before the treatment, it is determined that the treatment should not be performed, the information 152 of the treatment sequence and the content of the treatment is not output, and step 711 is performed. On the other hand, if it is determined that the post-treatment imaginary benefit exceeds the non-disposed pre-determined benefit, proceed to step 707. Here, as in step 307, it is determined that the operator must immediately start the treatment as the treatment sequence. Then, in step 710, the information 152 of the processing time sequence and the processing content will be output and notified to the operator. The operator who has been notified of the information 152 of the processing sequence and the content of the processing shall deal with the abnormality of the equipment P, and record the processing and operation information other than the processing.

Although the first and second embodiments of the present invention have been described above, the present invention described in the scope of the patent application is not limited to these embodiments and can be modified in various ways, but it should be easily understood by those in charge. .
