  Next, processing executed by the part ordering support apparatus 100 configured as described above will be described.

  FIG. 6 is a flowchart of processing executed by the parts ordering support apparatus 100.

  First, the part ordering support apparatus 100 calculates the remaining part life and registers the calculated remaining part life in the parts table 105a stored in the database unit 105 (step S101). Next, the part ordering support apparatus 100 calculates a part replacement time by using the remaining part life registered in the parts table 105a (step S102). Finally, the parts ordering support apparatus 100 displays information on parts that are assumed to have reached the end of their service life within a predetermined period, using the calculated replacement time (step S103).

  Details of the flowchart shown in FIG. 6 will be described below with reference to FIGS.

  FIG. 7 is a detailed flowchart of the process (step S101 in FIG. 6) relating to the registration of the remaining part life.

  First, the operating time acquisition unit 106a selects one component mounter 200 from the plurality of component mounters 200 (step S201). Subsequently, the operating time acquisition unit 106a selects one part from a plurality of parts constituting the selected component mounter 200 (step S202). Specifically, for example, the operating time acquisition unit 106a refers to the part table 105a stored in the database unit 105 to select one device ID from among a plurality of device IDs included in the part table 105a. . The operating time acquisition unit 106a selects one product number from a plurality of product numbers corresponding to the selected device ID.

  Then, the operation time acquisition unit 106a calculates the operation time (actual operation time) for each day when the component mounter 200 is actually operated from when the selected part is attached to the component mounter 200 to the present time. Obtained from the selected component mounter 200 (step S203).

  Next, the part remaining life calculation unit 106d refers to the consumable load rate table 105b stored in the database unit 105, and the part selected in step S202 and the actual operation time for each day acquired in step S203. Is acquired (step S204). Then, the remaining part life calculation unit 106d corrects the actual operating hours for each day acquired in step S203 using the acquired wear load factor (step S205).

  Specifically, for example, when the operation time acquisition unit 106a acquires “8 hours” as the actual operation time of a part with the part number “A” on one day, the remaining part life calculation unit 106d displays the consumption shown in FIG. By referring to the load factor table 105b, the consumption load factor “0.8” corresponding to the product number “A” and the actual operation time “8 hours” is acquired. Then, the part remaining life calculation unit 106d calculates the corrected actual operation time “6.4 hours” by multiplying the actual load operation time “8 hours” by the consumption load factor “0.8”.

  Next, the part remaining life calculation unit 106d refers to the part table 105a stored in the database unit 105 to obtain the part life of the part selected in step S202 (step S206). Specifically, for example, when the part of the product number “A” is selected, the remaining part life calculation unit 106d acquires “1000 hours” as the part life by referring to the part table 105a shown in FIG. To do.

  Next, the part remaining life calculation unit 106d calculates the part remaining life by calculating the difference between the sum of the actual operating hours for each day corrected in step S205 and the part life acquired in step S206. (Step S207).

  Specifically, for example, it is assumed that the day of the actual operating time “8 hours” is 20 days and the day of “24 hours” is 3 days. In this case, the part remaining life calculation unit 106d uses the corrected actual operation time “6.4 hours” and “24 hours” to calculate the part remaining life of the part “A” as “800 hours”. (= 1000− (6.4 × 20 + 24 × 3)).

  Next, the part remaining life registration unit 106e registers the calculated part remaining life in the parts table 105a stored in the database unit 105 (step S208).

  Then, the operating time acquisition unit 106a determines whether or not all the parts to be exchanged constituting the selected component mounter 200 have been selected (step S209). Here, when all the parts have not been selected (No in Step S209), the operation time acquisition unit 106a has not yet been selected from the plurality of parts constituting the selected component mounter 200. One part is selected (step S202). On the other hand, when all the parts to be replaced are selected (Yes in Step S209), the operating time acquisition unit 106a determines whether all of the plurality of component mounters 200 have been selected (Step S210).

  Here, when all the component mounting machines 200 have not been selected (No in step S210), the operation time acquisition unit 106a again mounts one component mounting that has not yet been selected from the plurality of component mounting machines 200. The machine 200 is selected (step S201). On the other hand, when all the component mounters 200 have been selected (Yes in step S210), the parts ordering support apparatus 100 executes the process in step S102 in FIG.

  FIG. 8 is a detailed flowchart of the process (step S102 in FIG. 6) relating to the calculation of the part replacement time.

  First, the operating time acquisition unit 106a selects one component mounter 200 from the plurality of component mounters 200 (step S301). Subsequently, the operating time acquisition unit 106a selects one part from among a plurality of parts to be replaced that configure the selected component mounter 200 (step S302). Specifically, for example, the operating time acquisition unit 106a refers to the part table 105a stored in the database unit 105 to select one device ID from among a plurality of device IDs included in the part table 105a. . The operating time acquisition unit 106a selects one product number from a plurality of product numbers corresponding to the selected device ID.

  Subsequently, the operating time acquisition unit 106a acquires the operating time per day of the component mounter 200 from the component mounter 200 selected in Step S301 (Step S303).

  Next, the replacement time calculation unit 106b refers to the consumable load rate table 105b stored in the database unit 105, so that the part selected in step S302 and the operation time per day acquired in step S303 are obtained. The corresponding consumption load factor is acquired (step S304). Then, the replacement time calculation unit 106b corrects the operating time per day acquired in step S303 using the acquired consumption load rate (step S305).

  Specifically, for example, when the operation time acquisition unit 106a acquires “8 hours” as the operation time per day for the part of the product number “A”, the replacement time calculation unit 106b displays the wear load shown in FIG. By referring to the rate table 105b, the wear load rate “0.8” corresponding to the product number “A” and the operating time “8 hours” is acquired. Then, the replacement time calculating unit 106b calculates the corrected operating time “6.4 hours” by multiplying the operating load “8 hours” by the consumption load factor “0.8”.

  Next, the replacement time calculation unit 106b refers to the part table 105a stored in the database unit 105 to acquire the remaining part life of the part selected in step S302 (step S306). Specifically, for example, when the part of the product number “A” is selected, the replacement time calculation unit 106b acquires the remaining part life “800 hours” by referring to the parts table 105a shown in FIG. .

  Next, the replacement time calculation unit 106b calculates the replacement time using the operation time per day corrected in step S305 and the remaining part life obtained in step S306 (step S307). Specifically, the replacement time calculation unit 106b calculates, as the replacement time, a value obtained by dividing the acquired remaining part life by the corrected operating time per day.

  More specifically, for example, it is assumed that the operating time acquisition unit 106a acquires the operating time “24 hours” per day of the component mounter 200 whose device ID is “MA”. In this case, referring to the consumable load factor table 105b shown in FIG. 4, the replacement time calculation unit 106b acquires “1” as the consumable load factor of the part of the product number “A”. Further, the replacement time calculation unit 106b reads “800 hours” as the remaining part life corresponding to the product number “A” from the parts table 105a shown in FIG. Then, the replacement time calculation unit 106b sets the replacement time of the part of the product number “A” attached to the component mounter 200 with the device ID “MA” as “33.3 days” (= 800 / (24 × 1)). And calculate.

  Further, for example, it is assumed that the operating time acquisition unit 106a acquires the operating time “8 hours” per day of the component mounter 200 with the device ID “MD”. In this case, referring to the consumable load factor table 105b shown in FIG. 4, the replacement time calculation unit 106b acquires “1” as the consumable load factor of the part of the product number “A”. Further, the replacement time calculation unit 106b reads “800 hours” as the remaining part life corresponding to the product number “A” from the parts table 105a shown in FIG. Then, the replacement time calculation unit 106b sets the replacement time of the part of the product number “A” attached to the component mounter 200 with the device ID “MD” as “125 days” (= 800 / (8 × 0.8)). And calculate.

  Next, the operating time acquisition unit 106a determines whether or not all the parts to be replaced that constitute the selected component mounter 200 have been selected (step S308). Here, when all the parts to be exchanged have not been selected (No in step S308), the operation time acquisition unit 106a again selects from the plurality of parts constituting the selected component mounter 200 again. One part that has not been selected is selected (step S302). On the other hand, when all the parts to be replaced are selected (Yes in step S308), the operating time acquisition unit 106a determines whether all of the plurality of component mounters 200 have been selected (step S309).

  Here, when all the component mounters 200 have not been selected (No in step S309), the operation time acquisition unit 106a again selects one component mounter that has not yet been selected from the plurality of component mounters 200. The machine 200 is selected (step S301). On the other hand, when all the component mounters 200 have been selected (Yes in step S309), the parts ordering support apparatus 100 executes the process in step S103 in FIG.

  FIG. 9 is a detailed flowchart of the processing related to the display of part information (step S103 in FIG. 6).

  First, the part order support unit 106c acquires a period for determining a part to be displayed (step S401). For example, the part ordering support unit 106 c acquires the period input by the user via the input unit 103. Note that the part ordering support unit 106c may hold a predetermined period. Subsequently, the part ordering support unit 106c extracts parts whose replacement time is included in the acquired period (step S402).

  Next, the part order support unit 106c refers to the part table 105a and the inventory management table 105c stored in the database unit 105, thereby acquiring the extracted part quantity, inventory quantity, and remaining order quantity (step S403). . Finally, the parts ordering support unit 106c causes the display unit 102 to display information on parts including the acquired quantity, the number of stocks, and the remaining number of orders (Step S404).

  Next, screens displayed by the parts ordering support apparatus 100 will be described with reference to FIGS. 10 and 11.

  FIG. 10 is a diagram illustrating an example of a repair part extraction screen.

  As shown in FIG. 10, the user inputs the operating status of each component mounter 200 on the repair part extraction screen. Then, the user presses a parts extraction button for specifying a period for extracting the parts and starting extraction of the parts.

  Thus, after the user presses the part extraction button, the operating time acquisition unit 106a acquires the operating time set on the screen. Then, the replacement time calculation unit 106b calculates the replacement time based on the acquired operating time. Furthermore, the part ordering support unit 106c extracts a part whose replacement time is included within a period designated by the user. Then, the parts ordering support unit 106c displays the extracted parts information on a repair parts ordering screen as shown in FIG.

  FIG. 11 is a diagram illustrating an example of a repair parts ordering screen.

  As shown in FIG. 11, on the repair part ordering screen, information on parts including a replacement time within a specified period is displayed. The part information includes the product number, part name, quantity, inventory quantity, remaining order quantity, and replacement time. The quantity displayed here is the number of parts whose replacement time is included within the specified period. The user inputs the number of arrangements while referring to the part information displayed on the screen. Then, the user places an order for the entered number of parts to the manufacturer by pressing the part order button.

  In addition, the part ordering support apparatus 100 according to the present embodiment can calculate the remaining part life more accurately by calculating the remaining part life based on the past actual operation status of the component mounter 200. Then, by calculating the part replacement time using the part remaining life calculated in this way, the part ordering support apparatus 100 can calculate a more accurate replacement time.

  In addition, the parts ordering support apparatus 100 according to the present embodiment is more accurate by using the actual operation time corrected according to the characteristics related to the wear of parts, such as parts that promote deterioration when continuously operated. The remaining part life can be calculated.

  Hereinafter, a specific example of the effect of the part ordering support apparatus 100 according to the present embodiment will be described with reference to FIG.

  FIG. 12A is a view for explaining the quantity of parts displayed on the repair part ordering screen by the conventional parts ordering support apparatus. FIG. 12B is a view for explaining the quantity of parts displayed on the repair parts ordering screen by the parts ordering support apparatus 100 according to the present embodiment.

  In FIG. 12A and FIG. 12B, there are six component mounters A to F, which are parts ordering targets. Each of these six component mounters 200 has six parts A attached thereto. The remaining life of these parts A is all “800 hours”.

  In the case of a conventional parts ordering support apparatus, as shown in FIG. 12A, the parts replacement time is assumed on the assumption that all the component mounting machines 200 are operated 24 hours a day (full operation). Was calculated. Therefore, the number of parts A that need to be replaced within two months (the number of replacements) was calculated to be 36, which is the same as the number of parts A attached to all the component mounting machines 200.

  On the other hand, in the case of the parts ordering support apparatus 100 according to the present embodiment, as shown in FIG. 12B, the replacement time is calculated based on the operating time per day of each component mounter 200. In the case of parts that promote deterioration when continuously operated or parts that reduce deterioration when the continuous operation time is short, the operation time depends on the length of operation time per day. It is corrected. As a result, the number of parts A that need to be replaced within two months (the number of replacements) is the number of parts A attached to the three component mounting machines 200 of the component mounting machines A to C that are in full operation. Is calculated.

  As described above, the parts ordering support apparatus 100 according to the present embodiment calculates the replacement time of the parts according to the operating time per day of the component mounting machine 200, so it must be replaced within the designated period. It is possible to avoid presenting information of parts having no part to the user.

  The parts ordering support apparatus according to the present invention has been described based on the embodiments. However, the present invention is not limited to these embodiments. Unless it deviates from the meaning of this invention, what made the various deformation | transformation which those skilled in the art conceivable to this Embodiment is also contained in the scope of the present invention.

  For example, in the above embodiment, the operation time per day acquired by the operation time acquisition unit 106a has been described mainly in the case where the operation time acquisition unit 106a is the same for all days. Different operating hours per day may be obtained. In that case, the replacement time calculation unit 106b corrects the operating time per day for each day. Then, when the corrected operation time for each day is integrated in time series, the replacement time calculation unit 106b calculates the time when the integrated time exceeds the remaining part life as the replacement time. Further, the repair part extraction screen shown in FIG. 10 is a screen on which the operating status can be set for each day.

  Further, in the above embodiment, the part remaining life calculation unit 106d does not consider whether or not the maintenance work is performed on the parts attached to the component mounting machine 200 when calculating the part remaining life. However, the remaining part life may be calculated in consideration of whether maintenance work is being performed. In other words, the part remaining life calculation unit 106d allows the parts remaining life to be shorter when the maintenance work is not performed on the parts attached to the component mounter 200 than when the maintenance work is performed. The remaining life may be calculated. In this case, the part remaining life calculation unit 106d acquires information regarding the maintenance work from the component mounter 200. Then, when it is determined that the maintenance work is not performed based on the acquired information, the part remaining life calculation unit 106d corrects the part remaining life to be shortened. As a result, the remaining part life can be calculated based on the maintenance status of the parts attached to the component mounter 200, and thus a more accurate part remaining life can be calculated. The maintenance work is a work performed to maintain the performance of the parts, for example, replenishment of lubricant such as grease to the parts, cleaning of the parts, and the like.

  In the above embodiment, the operating time and the actual operating time acquired by the operating time acquisition unit 106a are the operating time and the actual operating time per day, but are not necessarily the operating time and the actual operating time per day. Need not be. For example, the operating time acquisition unit may acquire operating time per week or actual operating time. In this case, the consumable load factor table 105b stores consumable load factors corresponding to operating hours per week.

  In the above embodiment, the consumable load factor is set so that the value increases as the operating time per day is longer. However, in the case of a part or the like whose deterioration is accelerated by repeated starting and stopping. Alternatively, the value may be set to be smaller as the operating time per day is longer. Further, the consumable load factor is not necessarily stored in the table in association with the operation time. For example, the parts ordering support apparatus may store a mathematical formula for calculating the wear load rate using the operation time per predetermined period. In this case, the replacement time calculation unit 106b and the part remaining life calculation unit 106d correct the operating time using the stored mathematical formula.

  Further, in the above embodiment, the case where the production apparatus is the component mounting machine 200 has been described. It is not limited to a mounting machine. For example, the production apparatus may be a screen printing machine, an adhesive application machine, a reflow machine, an inspection machine, or the like.

  The present invention accurately calculates the replacement time of the parts that make up the production equipment, and supports the user's ordering of parts using the calculated replacement time, thereby contributing to a reduction in the inventory of parts that need replacement due to their service life. It can be applied to a parts ordering support device that can be used.
