[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-365052 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-83002 [Patent Document 3] Japanese Patent Application Laid-Open No. 2006-84378 [Patent Document 4] Japanese Patent Application Laid-Open No. 2002-193224 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional technology, the replacement timing of a part is generally determined from a durability test of the part, and the above-mentioned reference value is calculated based on this replacement timing. Therefore, in conventional technology, there is a problem that the maintenance timing cannot be notified unless the part has been subjected to a durability test in advance.

[0005] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide a management device that can notify the timing of maintenance even if the useful life of a part is unknown, such as in the case of parts or items that have not undergone durability testing and are products of other companies. [Means for solving the problem]

[0006] The gist of one embodiment of the management device is a management device that notifies the next maintenance date for a device having multiple parts, and is equipped with a registration unit that registers the date and time when the part was repaired or replaced as the current maintenance date and time, and a calculation unit that, when registering the current maintenance date and time, if the previous maintenance date and time has been registered, calculates the next maintenance date and time based on the time difference from the previous maintenance date and time to the current maintenance date and time. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a management device that can notify the maintenance timing even for parts that have not undergone durability testing. [Brief explanation of the drawings]

[0009] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description of the drawings, identical or similar parts are designated by identical or similar reference numerals. However, it should be noted that the drawings are schematic, and the dimensional ratios and the like may differ from those of the actual parts. Therefore, specific dimensions and the like should be determined with reference to the following description. Furthermore, parts in the drawings may have different dimensional relationships and ratios. In this specification and the drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant description, and elements not directly related to the present invention are not shown.

[0010] (First embodiment) A management device 10 according to a first embodiment of the present invention will be described below with reference to Figures 1 to 5. Figure 1 is a diagram showing an example of the overall configuration of a production line managed by the management device 10 according to this embodiment, Figure 2 is a diagram showing an example of functional blocks of the management device 10 according to this embodiment, Figure 3 is a diagram showing an example of maintenance dates and times registered in the registration unit 12 of the management device 10 according to this embodiment, and Figures 4 and 5 are diagrams showing examples of screens displayed on the display unit 15 of the management device 10 according to this embodiment.

[0011] As shown in Fig. 1, the production line 1 according to this embodiment includes a weighing and packaging device 2 that packs the combined and weighed products into bags, an X-ray inspection device 3, a weight inspection device (weight checker) 4, a bag thickness / seal inspection device 5, and a boxing device 6. Note that the production line 1 does not necessarily have to include all of the devices 2 to 6, and may include other devices.

[0012] Here, the weighing and packaging device 2 is a device that manufactures bagged products (hereinafter referred to as "items") with a fixed content by placing a bag-making and packaging device below a combination weighing device that combines and weighs items to a predetermined weight. The X-ray inspection device 3 is a device that generates X-ray images of such items while transporting them and inspects the items based on the X-ray images (for example, inspection of the number of items contained, inspection of foreign matter contamination, inspection of missing items, inspection of cracks and chips, etc.). The weight inspection device 4 is a device that weighs the items while transporting them and inspects for excess or deficiency of contents. The bag thickness / seal inspection device 5 is a device that inspects the thickness and seal condition of the item bags. The boxing device 6 is a device that packs the bagged items into cardboard boxes after these inspections have been completed.

[0013] The management device 10 is connected to each of the devices 2 to 6 via a network and acquires various information such as operating conditions, operating status, and operation history from each of the devices 2 to 6. It also acquires information such as the maintenance status of the device on which maintenance was performed and whether or not parts have been replaced from a tablet or PC carried by the worker. The management device 10 manages each of the devices 2 to 6 based on the acquired maintenance information and notifies each of the devices 2 to 6 of the next maintenance date.

[0014] As shown in FIG. 2, the management device 10 includes an acquisition unit 11, a registration unit 12, a calculation unit 13, and a display unit 14.

[0015] The acquisition unit 11 acquires maintenance information for each of the devices 2 to 6 that has undergone maintenance from a personal computer or the like of the maintenance worker. For example, the acquisition unit 11 may acquire the date and time of repair or replacement of parts when maintenance was performed on each of the devices 2 to 6. Furthermore, when maintenance information is uploaded to a predetermined server from a tablet or the like of the worker, the acquisition unit 11 may acquire various information related to the devices 2 to 6 from the predetermined server.

[0016] The registration unit 12 registers, as the date and time of this maintenance, the date and time when a part of each of the devices 2 to 6 was repaired or replaced. For example, the registration unit 12 may register the date and time of this maintenance based on the information acquired by the acquisition unit 11.

[0017] 3, the registration unit 12 may also manage past maintenance dates and times (dates and times of the previous maintenance) and the timing of the next maintenance. In the example of FIG. 3, the date and time of the second maintenance is the date and time of the previous maintenance, the date and time of the third maintenance is the date and time of the current maintenance, and the date and time of the fourth maintenance is the date and time of the next maintenance. Note that in the example of FIG. 3, the registration unit 12 does not manage the date and time of the first maintenance. Also, in FIG. 3, only the year, month, and day are listed as the maintenance dates and times, but the time may also be listed as necessary. For this reason, the date and time are used here.

[0018] When registering the current maintenance date and time, if the previous maintenance date and time has been registered, the calculation unit 13 calculates the next maintenance time based on the time difference (part usage period) from the previous maintenance date and time to the current maintenance date and time.

[0019] With this configuration, even if the introduction date and time of a part is not managed because it is made by another company, if the date and time of the previous maintenance of the part in question is registered, the next maintenance date and time of the part can be appropriately determined.

[0020] In addition, the calculation unit 13 may calculate the next maintenance date and time based on the time difference between the previous maintenance date and time and the current maintenance date and time, and may determine the period from the calculated next maintenance date and time to a specified date and time as the next maintenance time.

[0021] The management device 10 can notify the maintenance target device of the next maintenance period at a predetermined timing (for example, a predetermined date and time before the start date and time of the next maintenance period).

[0022] Here, the management device 10 may notify the worker performing the maintenance by sending an email to the tablet or personal computer of the worker performing the maintenance with information about the maintenance performed so far and the time when the next maintenance will be performed, or may notify the worker by displaying the arrival of the maintenance time on the screen of the target device, etc.

[0023] With this configuration, the maintenance worker and the manufacturer of the target device can know the next maintenance date in advance, so that maintenance (repair, replacement, etc.) of the target part can be performed at the appropriate time. This makes it possible to avoid unexpected situations such as a sudden stoppage of a device that constitutes a manufacturing line during operation.

[0024] In addition, when the date and time of the second previous maintenance and the date and time of the previous maintenance are registered in the registration unit 12, the calculation unit 13 may determine the next maintenance time based on the average of the time difference (parts usage period) between the date and time of the second previous maintenance and the date and time of the previous maintenance and the date and time of the current maintenance (parts usage period).

[0025] Alternatively, the calculation unit 13 may determine the next maintenance timing based on the average of the usage periods of all parts up to the present time.

[0026] The display unit 14 displays the registered maintenance information on various screens.

[0027] For example, a maintenance worker can identify the equipment to be maintained using a tablet or PC, check the maintenance status up to now, and when the replacement of parts or repairs of the equipment is completed, enter the maintenance details, including the date and time of this maintenance, on the "New Repair Details Registration Screen (see Figure 4)."

[0028] On the "New Repair Content Registration Screen" shown in Figure 4, "Equipment Serial Number" is an item for entering identification information for the target device, "Repair Equipment Part" is an item for entering (identifying) the part that underwent maintenance, and "Repair Date" is an item for entering the date and time of this maintenance.

[0029] When the maintenance information thus input is input to the acquisition unit 11 of the management device 10 via the Internet, the registration unit 12 registers the date and time of the current maintenance based on the input maintenance information, and if the date and time of the maintenance before last and the date and time of the previous maintenance have been registered, the calculation unit 13 may determine the time of the next maintenance based on the average of the time difference (parts usage period) between the date and time of the previous maintenance and the date and time of the previous maintenance and the date and time of the current maintenance (parts usage period).

[0030] Furthermore, by operating the worker's tablet or PC, for example, the "Past Repair History Search List Display Screen" shown in Figure 5 can be displayed, making it possible to check the details of past maintenance work even if the maintenance worker is replaced.

[0031] The registration unit 12 may also manage the daily operating hours of the device (component). In this case, the calculation unit 13 may determine the next maintenance timing by taking into account the operating hours in addition to the above-mentioned time difference. Furthermore, if the next replacement dates and times are registered for a plurality of parts, the notification may be made according to the earliest replacement date and time.

[0032] Furthermore, the calculation unit 13 may determine the next maintenance timing by taking into consideration the environment in which the device is used in addition to the above-mentioned time difference.

[0033] According to the above embodiment, it is possible to notify the maintenance timing even for parts that have not undergone durability testing.

[0034] Although the present invention has been described in detail using the above-described embodiments, it is clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is intended to be illustrative and explanatory and does not have any limiting meaning on the present invention. [Explanation of symbols]
