  The maintenance management support device 1 accepts the input of the production data A at the time of the latest production (S1 in FIG. 4), and each data of the production data A corresponds to the product information DB 7a of the production information DB 7 and the corresponding item of the process information DB 7b. Record as data.

  Further, the maintenance management support apparatus 1 uses the component information DB 6a and the failure mode DB 6b of the facility information DB 6 to obtain the part number 101, year / form 114, failure date 102, failure mode 103, and failure cause 104 of each part of the printing press. , Failure data 105, occurrence condition 115, last maintenance date 116, countermeasure method 106, required time 108, required number of persons 109, labor cost 110, part unit price 111, damage amount 112, damage amount contribution rate 117 (FIG. 6 (b)) is read (S2).

  Then, the maintenance management support device 1 calculates the input quantity at the time of the latest product production as the sum of the production quantity 122 and the waste paper 123 as the product production status from the production data A, and calculates the operation amount as the operation time. 126 and the operation speed 127 (S3).

  Next, the maintenance management support apparatus 1 refers to the risk information DB 8 and determines whether there is data corresponding to the part number 101 of each part of the equipment data B (S4).

  The maintenance management support apparatus 1 uses the risk data C (FIG. 6C) corresponding to the part number 101 from the risk information DB 8 for the part (S4; Yes) whose data corresponding to the part number 101 is in the risk information DB 8. As reference), part number 101, failure date 102, failure mode 103, previous maintenance date 116, countermeasure method 106, damage amount 112, production quantity 122, waste paper 123, operation time 126, operation speed 127, maintenance cost 129 Obtain (S5).

  Then, the input quantity after the previous maintenance date is calculated from the production quantity 122 and the waste paper 123 of the risk data C, and the input quantity at the time of the latest product production calculated in S3 is added thereto. Similarly, the operation amount after the previous maintenance date is calculated from the operation time 126 and the operation speed 127 of the risk data C, and the operation amount at the time of the latest product production calculated in S3 is added thereto. Further, the operation time 126 of the latest product production is added to the operation time 126 of the risk data C (S6). The input quantity, operation amount, and operation time calculated in this way are used for comparison in S8 described later.

  On the other hand, the maintenance management support device 1 does not perform the processing of S5 and S6 above for the parts (S4; No) for which the data corresponding to the part number 101 of the equipment data B is not in the risk information DB 8, and the input calculated in S3. The quantity, the operation amount, and the operation time 126 of the production data A are used in the comparison of S8 described later.

  Next, the maintenance management support apparatus 1 determines whether or not the failure mode DB 6b has a failure occurrence condition 115 corresponding to the component number 101 of each component in the equipment data B (S7).

  For a component that does not have the generation condition 115 (S7; No), the processing is terminated as it is. On the other hand, for the part having the generation condition 115 (S7; Yes), the generation condition 115 (input quantity, operation amount, operation time) is compared with the calculated input quantity, operation amount, operation time (S8). .

  If any of the calculated input quantity, operation amount, or operation time exceeds the generation condition 115 (S9; Yes), the maintenance management support apparatus 1 assumes that the part may be in failure, and the condition excess data D As shown in FIG. 6D, the part number 101 and the failure mode 103 corresponding to the occurrence condition 115 are recorded. In this way, the risk evaluation target parts are extracted, and the part number 101 and the failure mode 103 are recorded as the excess condition data D (S10).

  On the other hand, if the calculated input quantity, operation amount, and operation time are all equal to or lower than the generation condition 115 (S9; No), the process is terminated without setting the part as a risk evaluation target.

  As described above, the possibility of failure of each part is diagnosed, and the part extracted as the condition excess data D becomes a risk evaluation target thereafter. Here, the risk information DB 8 can be updated together. That is, when there is data corresponding to the part number 101 of the equipment data B in the risk information DB 8, the production quantity 122, the waste paper 123, the operation time 126, and the operation speed 127 indicate the latest production time indicated by the production data A. The production quantity 122, the waste paper 123, the operation time 126, and the operation speed 127 are added and updated. If there is no data corresponding to the part number 101 of the equipment data B, necessary information is acquired from the production data A, equipment data B, etc., and data corresponding to the part number 101 is newly created. .

(2-2. Risk assessment procedure)
In the present embodiment, when the above condition excess data D is input, the maintenance management support apparatus 1 accepts the input of the condition excess data D (S21 in FIG. 5) and manages it from the product information DB 7a and the process information DB 7b. Production data A including number 100, customer 118, product name 119, production date 120, lot 121, production quantity 122, waste paper 123, material 124, specification 125, operation time 126, operation speed 127, and sensor data 128 is acquired. (S22).

  Then, the maintenance management support apparatus 1 determines that between the data of the most recent production date 120 in the acquired production data A and the data of the previous production date 120 of the latest production date 120 having the same product name 119 as the data. Then, the waste paper 123 and the operation speed 127 are compared (S24).

When the amount of the latest damaged paper 123 is larger than the previous lost paper 123 and the latest operating speed 127 is lower than the previous operating speed 127 (S25; Yes), the damaged paper 123 is obtained by the following equation (1). Is calculated (S26), and the efficiency loss due to the decrease in the driving speed 127 is calculated by the following equation (2) (S27).
Amount of damaged paper = (the latest loss paper 123-the previous loss paper 123) x unit price x damage contribution ratio (1)
Efficiency damage amount = (previous driving speed 127-latest driving speed 127) x latest driving time 126 x unit price x damage contribution rate (2)

  Here, the unit price of equation (1) is the unit price of paper, and the unit price of equation (2) is the amount of damage per unit decrease in driving speed, and is stored in the storage unit 12 in advance. Further, as the damage contribution ratios of the equations (1) and (2), the sum of the damage contribution ratios 117 of the respective parts in the condition excess data D is used.

  Note that, in the determination of S24, if the latest damaged paper 123 is equal to or lower than the previous damaged paper 123 or the latest operating speed 127 is equal to or higher than the previous operating speed 127 (S25; No), the process will be described later in S28. Move on.

  In S28, the maintenance management support device 1 refers to the risk information DB 8, adds up the maintenance costs 129 of all the part numbers 101 of the condition excess data D, and calculates the total maintenance cost (S28).

  Further, the maintenance management support device 1 calculates the sum of the sum 112 of the damage amount 112 of all the part numbers 101 of the excess condition data D, the calculated lost paper damage amount, and the efficiency loss amount, and the excess condition data D The total damage amount due to all the parts with the part number 101 of (S29).

  Then, the maintenance management support apparatus 1 compares the calculated total damage amount with the total maintenance cost (S30).

  When the total damage amount is larger than the total maintenance cost (S30; Yes), the maintenance management support device 1 acquires necessary information from the condition excess data D, the risk information DB 8, etc. , Part number 101, failure mode 103, damage amount 112, maintenance cost 129, countermeasure method 106, maintenance part data E (see FIG. 6 (e)) is created, and the contents of maintenance part data E are stored. A warning to the effect that the proper maintenance timing of parts has been reached is displayed by displaying it on the display unit 14 or the like (S31).

  Further, the maintenance management support apparatus 1 writes each piece of maintenance part data E in the countermeasure status DB 9 (S32), erases and resets the data corresponding to the part number 101 etc. in the risk information DB 8 (S33), Terminate the process.

  On the other hand, if the total damage amount is equal to or less than the total maintenance cost in S30 described above (S30; No), the processing is terminated as it is because the maintenance timing is not yet reached.

  After this, the operator performs maintenance such as replacement of parts by referring to the warning of S31, and regarding the parts that have been maintained, the part number 101, failure occurrence date 102, failure mode 103, failure cause 104, failure indication 105, countermeasures The method 106, the execution date 107, the required time 108, the required number of people 109, the labor cost 110, the part unit price 111, the damage amount 112, the post-measurement situation 113, and the like are input as the maintenance data F (see FIG. 6 (f)). .

  When the maintenance management support apparatus 1 accepts the input of the maintenance data F, it records this in the maintenance information DB 5 and records data of items corresponding to the maintenance data F in the parts information DB 6a and the failure mode DB 6b. Further, the maintenance management support apparatus 1 compares the maintenance data F with the countermeasure status DB 9, and if there is data corresponding to the part number 101 of the maintenance data F in the countermeasure status DB 9, it is deleted and reset.

  It should be noted that each data in the countermeasure status DB 9 for which maintenance has not been performed may be continuously displayed on the display unit 14 of the maintenance management support apparatus 1 to warn that it is the maintenance timing of the parts.

  According to the maintenance management support device 1 of the present embodiment described above, it is possible to present an appropriate timing for maintenance from the viewpoint of maintenance cost and damage amount (risk) based on the result of failure diagnosis in consideration of the production status of the product. It is also applicable to the production of different types. In addition, by grasping the production status of the same product, it becomes possible to present a timing that takes into account the balance between the decline in equipment capacity and maintenance costs.

  Further, in the present embodiment, since the input quantity, the operation amount, and the operation time are compared with the failure conditions in S8, the possibility of component failure can be suitably diagnosed based on the relationship with the production status. However, the present invention is not limited to this, and only one of them may be used for comparison, and other factors than the above can be used for comparison as long as they indicate the production status of products.

  Also, in this embodiment, at the time of risk evaluation, pay attention to the waste paper and the operating speed as the production status, and compare with the maintenance cost of the parts in consideration of the amount of damage due to the increase in the waste paper and the decrease in the operating speed. Considering the risk due to the decline in equipment capacity, it is possible to present a suitable maintenance timing by comparing with the maintenance cost. Note that the production status in this case is not limited to the above-mentioned broken paper and the operation speed, but it is only necessary to pay attention to factors that cause damage due to the change.

  In addition, although the maintenance management support apparatus 1 of the present embodiment has been described with reference to an example applied to a printing press, the same technique can be applied to various production facilities. However, in the printing field, since the production status frequently changes depending on various types of printed items, it is particularly important that the maintenance management support apparatus 1 of the present embodiment can appropriately grasp the maintenance timing under such a situation.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
