[0028] A production management device according to one embodiment of the present disclosure includes: an acquisition unit that acquires production data and progress data, the production data indicating a production plan for producing a plurality of mounting substrates on which one or more components are respectively assembled on substrates by a production system, and the progress data indicating the production progress of the production system; and a plan processing unit that creates a production change adjustment plan for one or more component supply units that supply components respectively assembled on substrates by the production system based on the production plan indicated by the production data and the production progress indicated by the progress data, the production change adjustment plan indicating whether the production change adjustment respectively performed on the one or more component supply units is an internal production change adjustment or an external production change adjustment, the internal production change adjustment being a production change adjustment of components performed on a component supply unit loaded on a device body included in the production system, and the external production change adjustment being a production change adjustment of components performed on a component supply unit removed from the device body. In addition, the device body mentioned above is, for example, a body of a component assembly device.

[0029] Thus, based on the production progress in the production system, a production change adjustment plan is created, indicating whether the production change adjustment of each of the one or more component supply units is an internal production change adjustment or an external production change adjustment. Therefore, whether the production progress in the production system is later than the production plan or earlier than the production plan, an appropriate production change adjustment plan corresponding to the production progress can be created. In other words, the production change adjustment can be appropriately managed.

[0030] Specifically, in the production management device of the above-mentioned patent document 1, when planning production, the production change adjustment of the component supply unit is planned. However, sometimes the production does not proceed according to its production plan. As a result, from the perspective of the operating efficiency of the component assembly device, the originally planned production change adjustment may be inappropriate. Therefore, in a production management device involved in one embodiment of the present invention, in addition to the production plan, the production progress is also considered to create a plan for internal production change adjustment or a plan for external production change adjustment, thereby reducing the operating loss of the production system compared to the past.

[0031] In addition, it may also be that the production plan includes an initial production change adjustment plan for the one or more component supply units, and the plan processing unit further performs the following processing: judging whether the production progress at the processing time is ahead of the production plan; if the production progress is ahead of the production plan, judging whether the production change adjustment scheduled to be later than the processing time in the initial production change adjustment plan, that is, the subsequent production change adjustment, is the internal production change adjustment; if the subsequent production change adjustment is the internal production change adjustment, calculating the time when the internal production change adjustment is completed, that is, the internal production change adjustment completion time, based on the production progress at the processing time; and in the case of changing the subsequent production change adjustment from the internal production change adjustment to the external production change adjustment, calculating the time when the external production change adjustment is completed, that is, the external production change adjustment completion time, based on the production progress at the processing time, in creating the production change adjustment plan, the subsequent production change adjustment represented by the initial production change adjustment plan is changed from the internal production change adjustment to the external production change adjustment based on the production plan, the internal production change adjustment completion time and the external production change adjustment completion time, thereby creating the production change adjustment plan. The processing time is an arbitrary time, for example, an arbitrary time when production is performed by the production system, and the production change adjustment plan is created at the processing time.

[0032] Thus, when the production progress is ahead of the production plan, that is, when the production progress is fast, the subsequent production change adjustment included in the initial production change adjustment plan is changed from the internal production change adjustment to the external production change adjustment. In addition, the change is made based on the production plan, the internal production change adjustment completion time, and the external production change adjustment completion time, so that the production change adjustment plan that further improves the production efficiency relative to the advanced production progress can be created.

[0033] For example, when production progress is ahead of the production plan, the cart of the component supply unit loaded on the component assembly device of the production system can be returned to the production change adjustment area earlier than originally planned. At this time, depending on the production progress, there is a situation where the internal production change adjustment planned in the production plan can be changed to an external production change adjustment. By changing the internal production change adjustment with the operation loss of the component assembly device to the external production change adjustment without the operation loss, the operation loss of the component assembly device can be reduced.

[0034] In addition, it may be that the plan processing unit determines whether the completion time of the internal production change adjustment is later than the completion time of the external production change adjustment during the creation of the production change adjustment plan, and if the completion time of the internal production change adjustment is later than the completion time of the external production change adjustment, the subsequent production change adjustment is changed from the internal production change adjustment to the external production change adjustment.

[0035] As a result, the completion time of subsequent production change adjustment can be advanced, and production efficiency can be improved.

[0036] In addition, it may be that the plan processing unit, in creating the production change adjustment plan, determines whether the production completion time of the multiple mounting substrates is delayed compared to the production plan due to the change of the subsequent production change adjustment, and when the production completion time is not delayed, changes the subsequent production change adjustment from the internal production change adjustment to the external production change adjustment.

[0037] This can suppress the delay in the production completion timing of the plurality of mounting substrates caused by the change in the subsequent production changeover adjustment.

[0038] In addition, it may also be that the production plan includes an initial production change adjustment plan for the one or more component supply units, and in the case where the production change adjustment scheduled to be later than the processing time in the initial production change adjustment plan, that is, the subsequent production change adjustment, is the external production change adjustment performed on the component supply unit in units of groups in order to produce the mounting substrates of each of the multiple varieties included in the group, the plan processing unit further performs the following processing: judging whether the production progress at the processing time is later than the production plan; and in the case where the production progress is later than the production plan, judging whether the completion time of the external production change adjustment on the unit of groups becomes later than the production start time of the mounting substrate of the group included in the production plan, and in the creation of the production change adjustment plan, in the case where it is judged that the completion time of the external production change adjustment on the unit of groups becomes after the production start time, the production change adjustment for at least one variety included in the group is maintained as the external production change adjustment, and the production change adjustment of at least one other variety included in the group is changed from the external production change adjustment to the internal production change adjustment, thereby creating the production change adjustment plan.

[0039] For example, when production progress is later than the production plan, the subsequent production change adjustment on a group basis may not be in time before the production of the mounting substrate of the group starts. However, in a production management device involved in one embodiment of the present disclosure, when the subsequent production change adjustment on a group basis is not in time, the production change adjustment is changed from external production change adjustment to internal production change adjustment on a variety basis. Thus, for a variety included in the group, for example, the first production, the production change adjustment of the variety can be made in time before the production of the variety starts. As a result, it is possible to suppress the production stop due to the incomplete production change adjustment, that is, it is possible to suppress the occurrence of non-operating periods of the production system.

[0040] For example, by changing at least the external production changeover of the item scheduled to be produced last in the group to the internal production changeover, production of the item scheduled to be produced first can be started earlier, thereby reducing the operation loss of the production system.

[0041] In addition, it may be that, in creating the production change adjustment plan, the planning processing unit maintains the production change adjustment for the variety of the mounting substrate produced initially in the group, i.e., the first variety, as the external production change adjustment, and changes the production change adjustment of each of the remaining at least one variety included in the group except the first variety from the external production change adjustment to the internal production change adjustment, thereby creating the production change adjustment plan.

[0042] This can further suppress the occurrence of non-operation periods, that is, can further reduce the operation loss of the production system.

[0043] In addition, it may also be that the plan processing unit further performs the following processing: judging whether the external production change completion time of the external production change of the first variety in the created production change adjustment plan is later than the previous production completion time when the production of the mounting substrate performed before the group production is completed; in the case where it is judged that the external production change completion time is later than the previous production completion time, judging whether there is a second variety in the remaining at least one variety other than the first variety whose external production change takes a shorter time than the first variety; and in the case where it is judged that the second variety exists, swapping the production order of the first variety and the second variety, changing the production change of the first variety from the external production change to the internal production change, and changing the production change of the second variety from the internal production change to the external production change, thereby updating the created production change adjustment plan.

[0044] For example, even if the production change adjustment of the first variety included in the group is an external production change adjustment, and the production change adjustment of all other varieties included in the group is an internal production change adjustment, the production change adjustment of the first variety may not be in time before the production of the first variety starts. However, in a production management device involved in one embodiment of the present invention, when the production change adjustment of the first variety is too late, the production order of the first variety and the second variety is swapped. The external production change adjustment of the second variety takes less time than that of the first variety. Therefore, by changing the production change adjustment of the first variety and the production change adjustment of the second variety whose production order is swapped into an internal production change adjustment and an external production change adjustment, respectively, the production change adjustment of the second variety can be made in time before the production of the second variety starts. As a result, the occurrence of non-operating periods can be further suppressed.

[0045] Furthermore, the external production change adjustment in groups may include production change adjustment of at least one component commonly used in production of a plurality of varieties included in the group, that is, common production change adjustment.

[0046] This makes it possible to efficiently perform production changeover adjustments.

[0047] Furthermore, the production management device may further include a display unit that displays the created production change adjustment plan.

[0048] As a result, the operator of the production system can perform production change adjustments according to the created production change adjustment plan, thereby improving production efficiency.

[0049] Hereinafter, the embodiments will be described in detail with reference to the drawings.

[0050] In addition, the embodiments described below all represent general or specific examples. The numerical values, shapes, materials, structural elements, configuration positions of structural elements, connection methods, steps, and the order of steps shown in the following embodiments are examples, and their purpose is not to limit the present disclosure. In addition, for the structural elements in the following embodiments that are not recorded in the independent technical solutions that represent the highest level concept, they are described as arbitrary structural elements.

[0051] In addition, each figure is a schematic diagram and may not necessarily be a strictly illustrated figure. In addition, in each figure, the same symbol is marked for the same structural member. In addition, in the following embodiments, expressions such as approximately parallel are used. For example, approximately parallel not only means completely parallel, but also means substantially parallel, that is, including, for example, an error of several percent. In addition, approximately parallel means parallel within the range that can exert the effect based on the present disclosure. The same is true for other expressions using "approximately".

[0052] (Implementation Method)

[0053] [Production system]

[0054] Figure 1 This is a diagram showing an example of the configuration of a production system in this embodiment.

[0055] The production system 1 in the present embodiment includes, for example, two production lines L1 and L2 and a production management device 100 .

[0056] The lines L1 and L2 are each an example of a mounting substrate production facility, and produce mounting substrates by performing solder printing, component mounting, and reflow operations on substrates carried in from the upstream side, and carry out the produced mounting substrates to the downstream side.

[0057] The production management device 100 generates and outputs production data for producing mounting substrates for production lines L1 and L2, respectively. In addition, the production management device 100 can also communicate with these production lines L1 and L2 via wireless or wired communication. The wireless communication can be Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or a specific low-power wireless communication.

[0058] The production line L1 is equipped with a substrate supply device M1, a substrate handover device M2, a solder printing device M3, component assembly devices M4 and M5, a reflow device M6, and a substrate recovery device M7. In addition, the devices included in the production line L1 are arranged in the order of the substrate supply device M1, the substrate handover device M2, the solder printing device M3, the component assembly devices M4 and M5, the reflow device M6, and the substrate recovery device M7, and are connected in series. In addition, these devices are referred to as operating devices below. In addition, the production line L1 only needs to include the substrate supply device M1, at least one component assembly device and the substrate recovery device M7, and may not include all of the above-mentioned operating devices. In addition, in addition to the above-mentioned operating devices, the production line L1 may also include a solder coating device for coating solder on the substrate, a component insertion machine for mounting radial components or axial components on the substrate, and the like.

[0059] The substrate supply device M1 supplies the substrate for mounting substrates produced by the production line L1 to the solder printing device M3 via the substrate delivery device M2. The solder printing device M3 performs the above-mentioned solder printing operation. That is, the solder printing device M3 screen-prints solder on the substrate delivered from the substrate delivery device M2.

[0060] The component assembly devices M4 and M5 respectively perform the above-mentioned component assembly operation of assembling at least one component on the substrate. In addition, the production line L1 is equipped with two component assembly devices M4 and M5. However, the number of components is not limited to two, and can be one or more than three. In addition, it can be said that the mounting substrate is substantially produced by the component assembly operation performed by these component assembly devices M4 and M5.

[0061] The reflow soldering device M6 performs the above-mentioned reflow soldering operation. That is, the reflow soldering device M6 heats the substrate on which the components are assembled and brought in from the component assembly devices M4 and M5, solidifies the solder on the substrate, and joins the electrode portion of the substrate and the components. Specifically, the reflow soldering device M6 heats according to a given heating curve, thereby melting and solidifying the solder used for joining the components. Thus, the components are joined to the substrate by solder. The substrate recovery device M7 recovers the substrate on which the solder joint is performed from the reflow soldering device M6.

[0062] The production line L2 also has the same structure as the production line L1. In addition, in the present embodiment, the production lines L1 and L2 have the same structure, but they may have different structures from each other.

[0063] [Component assembly device]

[0064] Figure 2: is a diagram showing an example of the structure of the component assembly device M4. In the present embodiment, the component assembly device M5 also has the same structure as the component assembly device M4. In addition, in the present embodiment, the conveying direction of the substrate B is referred to as the X-axis direction, and the direction perpendicular to the X-axis direction is referred to as the Y-axis direction. The X-axis direction and the Y-axis direction are directions along the horizontal plane. Furthermore, the direction perpendicular to the X-axis direction and the Y-axis direction is referred to as the Z-axis direction. The positive side and the negative side in the X-axis direction are the downstream side and the upstream side in the conveying direction of the substrate B, respectively, and the positive side and the negative side in the Y-axis direction are the rear side (or the inner side) and the front side (or the front side) in the front-to-back direction, respectively. The positive side and the negative side in the Z-axis direction are the upper side and the lower side in the up-down direction, respectively. Figure 2 , the upper surface of the component mounting device M4 is shown.

[0065] The component mounting device M4 includes a base 4 , a substrate transport mechanism 5 , two component supply units 6 , two X-axis beams 9 , a Y-axis beam 8 , two mounting heads 10 , two component recognition cameras 11 , and two substrate recognition cameras 12 .

[0066] The substrate transport mechanism 5 includes two rails along the X-axis direction and is disposed at the center of the base 4. The substrate transport mechanism 5 transports the substrate B carried in from the upstream side and positions and holds the substrate B at a position for performing component mounting work.

[0067] The two component supply units 6 are arranged to sandwich the substrate conveying mechanism 5 in the Y-axis direction. In each component supply unit 6, a plurality of feeders 7 are arranged side by side along the X-axis direction. The feeders 7 feed the component tape containing the components at intervals in the tape feeding direction, thereby supplying the components to a position (hereinafter referred to as a component removal position) where the mounting head 10 removes the components.

[0068] In addition, a tray feeder, a rod feeder, or a bulk feeder may be arranged in the component supply unit 6. A tray feeder supplies components from a tray containing components. A rod feeder supplies components from a rod container containing components. A bulk feeder supplies components from a bulk container containing components.

[0069] The Y-axis beam 8 is disposed along the Y-axis direction on one side of the upper surface of the base 4 in the X-axis direction ( Figure 2 The two X-axis beams 9 are connected to the Y-axis beam 8 in a state along the X-axis direction and in a manner that allows free movement in the Y-axis direction.

[0070] The mounting head 10 is mounted on the two X-axis beams 9 so as to be movable in the X-axis direction. The mounting head 10 has a plurality of suction units 10a that can be raised and lowered while suctioning and holding the components. A suction nozzle 10b is provided at the front end of each suction unit 10a (see Figure 3).

[0071] The two mounting heads 10 are respectively moved in the X-axis direction and the Y-axis direction by driving the Y-axis beam 8 and the X-axis beam 9. Thus, the two mounting heads 10 respectively absorb and take out components from the component taking-out position of the feeder 7 of the component supply unit 6 corresponding to the mounting head 10 by the suction nozzle 10b, and mount them at the mounting point (or mounting position) of the substrate B positioned by the substrate conveying mechanism 5.

[0072] The two component recognition cameras 11 are respectively arranged between one of the two component supply units 6 and the substrate conveying mechanism 5. When the mounting head 10 that has taken out a component from the component supply unit 6 moves above the component recognition camera 11, the component recognition camera 11 photographs the component. In other words, the component recognition camera 11 photographs the component held by the mounting head 10, thereby recognizing the holding posture of the component.

[0073] The substrate recognition camera 12 is mounted on the plate 9a on which the mounting head 10 is mounted. Therefore, the substrate recognition camera 12 moves integrally with the mounting head 10. Such a substrate recognition camera 12 moves to the upper side of the substrate B positioned by the substrate conveying mechanism 5 along with the movement of the mounting head 10, and photographs a substrate mark (not shown) provided on the substrate B to recognize the position of the substrate B. In the process of mounting components on the substrate B by the mounting head 10, the mounting position is corrected based on the recognition result of the component by the component recognition camera 11 and the recognition result of the position of the substrate B by the substrate recognition camera 12.

[0074] Figure 3 is partially shown Figure 2 The component mounting device M4 has a function of mounting the component P on the substrate B.

[0075] like Figure 3 As shown, the component supply unit 6 includes a feeder base 13a, a plurality of feeders 7 mounted on the feeder base 13a, and a carriage 13 that supports the feeder base 13a.

[0076] The trolley 13 is configured to be freely loaded and unloaded relative to the respective main bodies of the component assembly devices M4 and M5, and is also provided with a cassette holder 15. The cassette holder 15 is configured to be capable of holding a plurality of component reels C. The component reel C accommodates the component tape 14 in a wound state. The plurality of component reels C are respectively held at the upper holding position Hu or the lower holding position Hd of the cassette holder 15. The component tape 14 pulled out from the component reel C held by the cassette holder 15 is assembled to the feeder 7. In addition, the feeder 7 may be arranged on a feeder base 13a provided on the base 4 instead of using the trolley 13. In addition, the component reel C may be held by the trolley 13 instead of the cassette holder 15.

[0077] In this way, the component supply unit 6 in this embodiment is loaded or unloaded relative to the main body of the component assembly devices M4 and M5 included in the production system 1. In addition, the main body of the component assembly devices M4 and M5 is also called the device main body, which includes the structure other than the component supply unit 6 of the component assembly devices M4 and M5.

[0078] In addition, in the present embodiment, as described above, the component mounting devices M4 and M5 have the same structure, but they may have different structures from each other.

[0079] [Functional structure of production management device and production line]

[0080] Figure 4 1 is a block diagram showing the functional configuration of the production management device 100 and the production lines L1 and L2.

[0081] The production management device 100 includes a control unit 101 , a data generation unit 102 , a plan processing unit 103 , a display unit 106 , an input / output unit 107 , an acquisition unit 108 , a production data storage unit DB1 , and a setting data storage unit DB2 .

[0082] The production data storage unit DB1 is a recording medium for storing production data indicating a production plan. The production plan is a plan for producing a plurality of mounted substrates each of which has one or more components mounted thereon by the production system 1.

[0083] The setting data storage unit DB2 is a recording medium for storing setting data for creating a production plan. The setting data indicates, for example, the number of production lines included in the production system 1, the number of carts 13 that can be used for production, the time required for production of mounting substrates, and the number of mounting substrates produced.

[0084] For example, the recording medium such as the production data storage unit DB1 and the setting data storage unit DB2 is a hard disk, RAM (Read Only Memory), ROM (Random Access Memory), or semiconductor memory, etc. In addition, such a recording medium may be volatile or nonvolatile.

[0085] The display unit 106 displays the production data stored in the production data storage unit DB1 and the setting data stored in the setting data storage unit DB2. Specific examples of the display unit 106 include a liquid crystal display, a plasma display, or an organic EL (Electro-Luminescence) display, but are not limited thereto.

[0086] The input / output unit 107 receives input data based on operations performed by an operator of the production system 1, for example, and outputs the input data to the control unit 101. Such an input / output unit 107 includes, for example, a keyboard, a touch sensor, a touch panel, or a mouse. In addition, the input / output unit 107 outputs data to the production lines L1 and L2 and inputs data from the production lines L1 and L2.

[0087] The data generation unit 102 generates production data and stores it in the production data storage unit DB1. For example, the data generation unit 102 generates production data based on the setting data stored in the setting data storage unit DB2. The data generation unit 102 sends the generated production data to the production lines L1 and L2 via the input / output unit 107.

[0088] As described above, the production data represents a production plan. The production plan includes the operation plans of the production lines L1 and L2 and the production change adjustment plans of the production lines L1 and L2. Here, the production data generated by the data generation unit 102 represents the initial production plan. Hereinafter, such an initial production plan is referred to as an initial production plan, and the above-mentioned production change adjustment plan included in the initial production plan is referred to as an initial production change adjustment plan. The production change adjustment plan includes the period for performing the production change adjustment, etc. The production change adjustment is an operation of replenishing one or more components for the component supply units 6 of the production lines L1 and L2, or replacing the components loaded in the component supply units 6, or extracting the components from the component supply units 6. For example, the replenishment, replacement, extraction, etc. of the components are performed in units of the feeder 7.

[0089] The acquisition unit 108 acquires production data from the production data holding unit DB1. Furthermore, the acquisition unit 108 acquires progress data from the production lines L1 and L2 respectively via the input / output unit 107. The progress data is data indicating the production progress of the production system 1. For example, the progress data indicates the type of mounting substrate produced when the progress data is generated, the number of mounting substrates produced up to this point, and the number of mounting substrates that have not been produced. In addition, the progress data may also indicate the respective states of the production lines L1 and L2 when the progress data is generated, such as in production or production stopped. Then, the acquisition unit 108 outputs the acquired production data and progress data to the planning processing unit 103.

[0090] The plan processing unit 103 changes the production plan represented by the production data, and replaces the production data held in the production data holding unit DB1 with the changed production data. Furthermore, the plan processing unit 103 transmits the changed production data to the production lines L1 and L2 via the input / output unit 107 .

[0091] For example, the planning processing unit 103 changes the initial production plan represented by the production data. That is, the planning processing unit 103 changes the initial production change adjustment plan based on the initial production plan and production progress represented by the production data and progress data. Thus, the initial production plan is changed and the changed production change adjustment plan is created.

[0092] In other words, the planning processing unit 103 creates a production change adjustment plan for one or more component supply units 6 that supply components that are respectively assembled on the substrate by the production system 1, based on the production plan and production progress represented by the production data and progress data. Here, the production change adjustment plan indicates whether the production change adjustment performed on the one or more component supply units 6 is an internal production change adjustment or an external production change adjustment. The internal production change adjustment is a production change adjustment of components performed on the component supply unit 6 loaded on the main body of the component assembly device M4 or M5 included in the production system 1. The external production change adjustment is a production change adjustment of components performed on the component supply unit 6 removed from the main body of the component assembly device M4 or M5.

[0093] Furthermore, the production change adjustment plan created by the plan processing unit 103 and the initial production change adjustment plan represented by the production data generated by the data generating unit 102 are displayed by the display unit 106 .

[0094] The control unit 101 controls various components other than the control unit 101 included in the production management device 100. For example, the control unit 101 controls various components based on input data of an operator received by the input / output unit 107.

[0095] The production line L1 includes an operation control unit 211 , an input / output unit 212 , a display unit 213 , an operation mechanism 214 , a progress data storage unit DB3 , and a production data storage unit DB4 .

[0096] The input / output unit 212, like the input / output unit 107 of the production management device 100, receives input data based on the operation performed by the operator of the production system 1, and outputs the input data to the operation control unit 211. Such an input / output unit 212 may also include, for example, a keyboard, a touch sensor, a touch panel, or a mouse. In addition, the input / output unit 212 outputs data to the production management device 100 and inputs data from the production management device 100. For example, the input / output unit 212 obtains the production data whenever the production data is sent from the production management device 100, and saves the production data in the production data storage unit DB4.

[0097] The display unit 213 displays the production data stored in the production data storage unit DB4, etc. The display unit 213 also displays the progress data stored in the progress data storage unit DB3, etc. Specific examples of the display unit 213 include a liquid crystal display, a plasma display, or an organic EL display, but are not limited thereto.

[0098] The operation mechanism 214 includes mechanisms such as the mounting head 10 and the feeder 7 for producing the mounting substrate.

[0099] The operation control unit 211 controls various components other than the operation control unit 211 included in the production line L1. For example, the operation control unit 211 controls various components based on input data of an operator received by the input / output unit 212. For example, the operation control unit 211 causes the operation mechanism 214 to perform at least one of the above-mentioned solder printing operation, component assembly operation, and reflow operation based on the production data stored in the production data storage unit DB4.

[0100] In addition, the operation control unit 211 generates or updates progress data indicating the production progress of the production line L1, and saves the generated or updated progress data in the progress data storage unit DB3. For example, if the progress data is not saved in the progress data storage unit DB3, the operation control unit 211 generates the progress data. However, the operation control unit 211 periodically updates the progress data saved in the progress data storage unit DB3. Furthermore, when the progress data is generated and when the progress data is updated, the operation control unit 211 sends the progress data to the production management device 100 via the input / output unit 212. Such progress data is, for example, periodically sent to the production management device 100.

[0101] The progress data storage unit DB3 is a recording medium for storing the above-mentioned progress data indicating the progress of production. The production data storage unit DB4 is a recording medium for storing the above-mentioned production data. For example, these recording media are hard disks, RAM, ROM, or semiconductor memories. In addition, such recording media can be volatile or non-volatile.

[0102] Thus, in the present embodiment, a production change adjustment plan is created to indicate whether the production change adjustment of each of the one or more component supply units 6 is an internal production change adjustment or an external production change adjustment based on the production progress in the production system 1. Therefore, whether the production progress in the production system 1 is later than the production plan or earlier than the production plan, an appropriate production change adjustment plan corresponding to the production progress can be created. In other words, the production change adjustment can be appropriately managed.

[0103] Specifically, in the production management device of the above-mentioned patent document 1, when planning production, the production change adjustment of the component supply unit is planned. However, sometimes the production is not carried out according to its production plan. As a result, from the perspective of the operating efficiency of the component assembly device, the production change adjustment originally planned is inappropriate. Therefore, in the production management device 100 of the present embodiment, in addition to the production plan, the production progress is also considered to create a plan for internal production change adjustment or a plan for external production change adjustment, so that the operating loss of the production system 1 can be reduced compared with the past.

[0104] In addition, in the present embodiment, the production management device 100 includes a display unit 106 for displaying the created production change adjustment plan. Therefore, the operator of the production system 1 can perform production change adjustment according to the created production change adjustment plan, and production efficiency can be improved.

[0105] [Change external production change adjustment to internal production change adjustment]

[0106] Figure 5 1 is a diagram showing an example of a process in which the production management device 100 changes an external production change adjustment to an internal production change adjustment. Figure 5 (a) represents the initial production plan. Figure 5 (b) shows a comparative example for comparison with the production plan after the change in this embodiment. Figure 5 (c) shows an example of a production plan changed by the production management device 100 in this embodiment.

[0107] like Figure 5 As shown in (a) of FIG. 1 , the data generation unit 102 generates production data representing the initial production plan and stores the production data in the production data storage unit DB1. Figure 5As shown in (a) of FIG. 1 , the initial production plan created by the data generating unit 102 includes initial operation plans of the production lines L1 and L2 and initial production changeover adjustment plans of one or more component supply units 6 .

[0108] The initial operation plan indicates the production period for producing the group, for example, for each group of mounting substrates including one or more varieties. In addition, although the group includes mounting substrates of one or more varieties, it can also be said that the group includes one or more varieties.

[0109] Specifically, the initial operation plan of production line L1 includes the production period of group 1 and the production period of group 2. Figure 5 In the example shown in (a), the end time of the production period of group 1 coincides with the start time of the production period of group 2. During the production period of group 1, one or more types of mounting substrates included in group 1 are produced by the operation of production line L1. In addition, during the production period of group 2, one or more types of mounting substrates included in group 2 are produced by the operation of production line L1.

[0110] The initial operation plan of production line L2 includes the production period of group 3 and the production period of group 4. Figure 5 In the example shown in (a), the end time of the production period of group 3 coincides with the start time of the production period of group 4. In the production process of group 3, one or more types of mounting substrates included in group 3 are produced by the operation of production line L2. In addition, in the production process of group 4, one or more types of mounting substrates included in group 4 are produced by the operation of production line L2.

[0111] The initial production adjustment plan indicates, for example, for each group, the production adjustment period for production adjustment for the group, the type of the production adjustment, and the relationship between the production adjustment and the initial operation plan. The types of production adjustment include the internal production adjustment and the external production adjustment mentioned above.

[0112] Specifically, the initial production change adjustment plan includes the production change adjustment period of the group 4 that performs external production change adjustment and the production change adjustment period of the group 2 that performs external production change adjustment. Figure 5 In the example shown in (a), the production change adjustment period of group 2 is later than the production change adjustment period of group 4.

[0113] During the production change adjustment period of the group 4, the production change adjustment of the group 4 is performed as an external production change adjustment. That is, during the production change adjustment period of the group 4, in a state where the trolley 13 of the component supply unit 6 is removed from the main body of the component assembly device M4 or M5, one or more feeders 7 required for the production of the group 4 are configured for the trolley 13.

[0114] During the production change adjustment period of group 2, the production change adjustment of group 2 is performed as an external production change adjustment. That is, during the production change adjustment period of group 2, after the production of group 3 executed by production line L2 is completed, the trolley 13 of the component supply unit 6 is unloaded from the main body of the component assembly device M4 or M5 of the production line L2. Then, one or more feeders 7 required for the production of group 2 are configured for the trolley 13. If the production change adjustment of group 2 is completed, the trolley 13 configured with the one or more feeders 7, that is, the component supply unit 6, is loaded on the main body of the component assembly device M4 or M5 of production line L1. Then, in production line L1, the production of group 2 starts.

[0115] In this way, the initial production change adjustment plan indicates whether the production change adjustment to be performed on one or more component supply units 6 is an internal production change adjustment or an external production change adjustment.

[0116] The production data indicating such an initial production plan is sent to the production lines L1 and L2, respectively. Then, the production lines L1 and L2 start production of one or more mounting substrates according to the initial production plan indicated by the production data. After the production starts, the production lines L1 and L2 periodically send progress data indicating the production progress to the production management device 100.

[0117] Here, the production progress in the production lines L1 and L2 may be behind the initial production plan. In such a case, the plan processing unit 103 of the production management device 100 changes the initial production plan based on the progress data transmitted from the production lines L1 and L2.

[0118] For example, Figure 5 As shown in (b), the initial production plan is changed according to the progress of production, which sometimes generates a non-operating period in the production system. Specifically, when the production progress of group 3 is late, the production completion time of group 3 in production line L2 is changed from time t1 to time t2. As a result, for the production adjustment of group 2, since the trolley used in the production of group 3 is required, the production adjustment period of group 2 is shifted backward. In addition, for the production of group 2, a component supply unit that has performed the production adjustment of group 2 is required. Therefore, the production period of group 2 is shifted backward. As a result, a non-operating period is generated between the production period of group 1 and the production period of group 2 in production line L1.

[0119] However, in the production management device 100 according to the present embodiment, the occurrence of the non-operating period can be suppressed.

[0120] Specifically, the plan processing unit 103 acquires the progress data via the acquisition unit 108 at the processing time. The processing time is the time when the production plan change process is performed. Figure 5 In the example shown, it is any time between time t0 and time t1 when the production of the group 3 is performed in the initial production plan. The plan processing unit 103 determines whether the production progress at the processing time is later than the initial production plan based on the progress data.

[0121] If the production progress is judged to be later than the initial production plan, the plan processing unit 103 changes the initial operation plan of the production line L2 included in the initial production plan according to the progress data. In other words, the plan processing unit 103 changes the production completion time of the group 3 in the production line L2 from time t1 to time t2.

[0122] As a result, the planning processing unit 103 further changes the initial production change adjustment plan included in the initial production plan. That is, since the production change adjustment of group 2 requires the trolley 13 used in the production of group 3, the planning processing unit 103 shifts the production change adjustment period of group 2 to a later time.

[0123] Here, the plan processing unit 103 determines whether the subsequent production change adjustment, which is a production change adjustment scheduled to be later than the processing time in the initial production change adjustment plan, is an external production change adjustment in groups. The external production change adjustment in groups is an external production change adjustment performed on the component supply unit 6 in order to produce the mounting substrates of each of the plurality of varieties included in the group.

[0124] exist Figure 5 In the case of example (c), the subsequent production change adjustment is an external production change adjustment of group 2 including mounting substrates of each of type D, type E, and type F. Therefore, in this case, the plan processing unit 103 determines that the subsequent production change adjustment is an external production change adjustment in groups. As a result, the plan processing unit 103 further determines whether the completion time t4 of the external production change adjustment in groups, that is, the completion time t4 of the external production change adjustment of group 2, becomes later than the production start time t3 of the mounting substrates of group 2 included in the initial production plan.

[0125] When the plan processing unit 103 determines that the completion time t4 of the external production change adjustment of the group 2 is after the production start time t3, it changes the initial production change adjustment plan of the component supply unit 6, thereby creating a production change adjustment plan. That is, the plan processing unit 103 maintains the production change adjustment for at least one product included in the group 2 as the external production change adjustment, and changes the production change adjustment of at least one other product included in the group 2 from the external production change adjustment to the internal production change adjustment.

[0126] For example, Figure 5As shown in (c), the planning processing unit 103 maintains the production change adjustment for the product D included in the group 2 as the external production change adjustment, and changes the production change adjustment for the products E and F included in the group 2 from the external production change adjustment to the internal production change adjustment. That is, the planning processing unit 103 maintains the production change adjustment for the product D, which is the product of the mounting substrate produced first in the group 2, as the external production change adjustment, and changes the production change adjustment for each of the remaining products E and F included in the group 2 except the product D from the external production change adjustment to the internal production change adjustment, thereby creating a production change adjustment plan. In addition, the product D is an example of the first product, and the products E and F are examples of at least one remaining product included in the group 2 except the first product. In addition, if the production change adjustment for each of the products E and F is, for example, an operation of simply loading 1 to 3 feeders 7 on the trolley 13, then when these production changes are performed by internal production change adjustment, the time required for the production change adjustment is shorter than when these production changes are performed by external production change adjustment that requires the trolley 13 to move. Therefore, even if the production changeover adjustment of each of the item E and the item F is changed from the external production changeover adjustment to the internal production changeover adjustment, the occurrence of a delay in the production completion time can be suppressed.

[0127] In this way, Figure 5 In the example shown, when the production progress is later than the initial production plan, the subsequent production change adjustment on a group basis may not be in time before the production of the mounting substrate of the group starts. However, in the production management device 100 in this embodiment, when the subsequent production change adjustment on a group basis is not in time, the production change adjustment is changed from external production change adjustment to internal production change adjustment on a variety basis. Thus, for variety D, which is included in the group and is produced initially, for example, the production change adjustment of variety D can be made in time before the production of variety D starts. As a result, it is possible to suppress the production stop due to the incomplete production change adjustment, that is, it is possible to suppress the occurrence of non-operation period of the production system 1. For example, by changing the external production change adjustment of at least variety F, which is scheduled to be produced last in the group, to an internal production change adjustment, it is possible to start the production of variety D, which is scheduled to be the first, earlier. Thus, the operation loss of the production system 1 can be reduced.

[0128] [Production adjustment and re-change processing]

[0129] Figure 6 This is a diagram showing an example of a process in which the production management device 100 re-changes the changed production change adjustment.

[0130] For example, Figure 5 As shown in (c) of FIG. 1 , even if the production adjustment of each of the product E and product F of group 2 is changed from external production adjustment to internal production adjustment, a non-operation period may occur. Figure 6As shown in (a), when the external production change adjustment completion time t5 of the product D is completed later than the production completion time t3 of the group 1, a non-operation period occurs in the production line L1. In addition, the production completion time t3 of the group 1 is the production completion time of the group 1 produced before the group 2, so it is also referred to as the previous production completion time t3 below.

[0131] Therefore, the plan processing unit 103 in this embodiment performs the following steps: Figure 5 In the case of a change in the production change adjustment shown in (c), it is determined whether the external production change adjustment completion time t5 is later than the production completion time t3 of group 1 in the production change adjustment plan created by the change. That is, the plan processing unit 103 determines whether the external production change adjustment completion time t5 of the first product, i.e., product D, is later than the previous production completion time t3 of the production completion of the mounting substrate performed before the production of group 2.

[0132] Then, when the planning processing unit 103 determines that the external production change adjustment completion time t5 is later than the previous production completion time t3, it determines whether there is a second variety among the remaining varieties E and F except variety D, which takes a shorter time than variety D for external production change adjustment. Here, when it is determined that there is such a second variety, the planning processing unit 103 switches the production order of variety D, which is the first variety, and the second variety. For example, the second variety is variety E.

[0133] That is to say, Figure 6 As shown in (b), the planning processing unit 103 swaps the production order of the first variety D and the second variety E. Specifically, the planning processing unit 103 swaps the production order of the variety D and the variety E in the group 2 shown in the operation plan of the production line L1. Then, the planning processing unit 103 changes the production change adjustment of the variety D as the first variety from the external production change adjustment to the internal production change adjustment, and changes the production change adjustment of the variety E as the second variety from the internal production change adjustment to the external production change adjustment. As a result, the initial production change adjustment plan is changed twice, thereby creating the final production change adjustment plan.

[0134] In this way, Figure 6In the example shown, even if the production change adjustment of the first variety included in the group is an external production change adjustment, and the production change adjustment of all other varieties included in the group is an internal production change adjustment, the production change adjustment of the first variety may not be in time before the production of the first variety starts. However, in the production management device 100 in this embodiment, when the production change adjustment of the first variety is too late, the production order of the first variety and the second variety is swapped. The external production change adjustment of the second variety takes less time than the first variety. Therefore, by changing the production change adjustment of the first variety and the production change adjustment of the second variety whose production order is swapped into an internal production change adjustment and an external production change adjustment, respectively, the production change adjustment of the second variety can be made in time before the production of the second variety starts. As a result, the occurrence of non-operating periods can be further suppressed.

[0135] Figure 7 This is a diagram showing an example of a common production change adjustment.

[0136] External production change adjustment based on a group can also include: production change adjustment of at least one component commonly used in the production of multiple varieties included in the group, that is, public production change adjustment. Figure 7 As shown, the production changeover of group 2 includes production changeover of at least one component commonly used in the production of variety E, variety D, and variety F, that is, common production changeover. More specifically, in the common production changeover, the feeder 7 commonly used in the production of variety E, variety D, and variety F is loaded on the trolley 13 as an external production changeover. Thus, production changeover can be performed efficiently.

[0137] [Change internal production change adjustment to external production change adjustment]

[0138] Figure 8 1 is a diagram showing an example of a process in which the production management device 100 changes the internal production change adjustment to the external production change adjustment. Figure 8 (a) represents the initial production plan. Figure 8 (b) shows an example of a production plan changed by the production management device 100 in this embodiment.

[0139] like Figure 8 As shown in (a) of FIG. 1 , the initial production plan created by the data generation unit 102 includes initial operation plans and initial production changeover adjustment plans for the production lines L1 and L2 .

[0140] The initial operation plan of the production line L1 indicates the production period of group 1, the production period of group 2, the production period of group 3, and the production period of group 7. Figure 8In the example shown in (a), the end time of the production period of group 2 coincides with the start time of the production period of group 3. During the production period of each of group 1, group 2, group 3, and group 4, one or more types of mounting substrates included in the group are produced by running the production line L1.

[0141] The initial operation plan of production line L2 indicates the production period of group 4, group 5, and group 6. During the production period of each of group 4, group 5, and group 6, one or more types of mounting substrates included in the group are produced by the operation of production line L2. Here, between the production period of group 5 and the production period of group 6, a period for internal production change adjustment of group 6 is set.

[0142] The initial production changeover plan indicates production changeover periods of Group 2, Group 5, Group 3, and Group 7 that respectively perform external production changeover, and a production changeover period of Group 6 that performs internal production changeover.

[0143] During the production change adjustment period of each of the groups 2, 5, 3 and 7, the production change adjustment of the group is performed as an external production change adjustment. That is, during the production change adjustment period of the group, in a state where the trolley 13 of the component supply unit 6 is unloaded from the main body of the component assembly device M4 or M5, one or more feeders 7 required for the production of the group are arranged for the trolley 13.

[0144] Specifically, during the production change adjustment period of group 2, the external production change adjustment for the production of group 2 is performed on the component supply unit 6. Then, if the production of group 1 in production line L1 is completed, the component supply unit 6 used for the production of group 1 is removed from the main body of the component assembly device M4 or M5 of production line L1. Then, the component supply unit 6 that has undergone the production change adjustment during the production change adjustment period of group 2 is loaded on the main body of the component assembly device M4 or M5 for the production of group 2.

[0145] During the production changeover of the group 5 , external production changeover for the production of the group 5 is performed on the component supply unit 6 used for the production of the group 1 and removed from the main body of the component mounting device M4 or M5 of the line L1 .

[0146] Then, when the production of group 4 in production line L2 is completed, the component supply unit 6 used for the production of group 4 is removed from the main body of the component assembly device M4 or M5 of production line L2. Thereafter, the component supply unit 6 that has been adjusted during the production adjustment period of group 5 is loaded on the main body of the component assembly device M4 or M5 for the production of group 5.

[0147] During the production changeover of the group 3, external production changeover for the production of the group 3 is performed on the component supply unit 6 used for the production of the group 4 and removed from the main body of the component mounting device M4 or M5 of the line L2.

[0148] Then, when the production of group 2 in production line L1 is completed, the component supply unit 6 used for the production of group 2 is removed from the main body of the component assembly device M4 or M5 of production line L1. Thereafter, the component supply unit 6 that has been adjusted during the production adjustment period of group 3 is loaded on the main body of the component assembly device M4 or M5 for the production of group 3.

[0149] During the production changeover of the group 7 , external production changeover for the production of the group 7 is performed on the component supply unit 6 used for the production of the group 2 and removed from the main body of the component mounting device M4 or M5 of the line L1 .

[0150] Then, when the production of group 3 in production line L1 is completed, the component supply unit 6 used for the production of group 3 is removed from the main body of the component assembly device M4 or M5 of production line L1. Thereafter, the component supply unit 6 that has been adjusted during the production adjustment period of group 7 is loaded on the main body of the component assembly device M4 or M5 for the production of group 7.

[0151] On the other hand, during the production change adjustment period of group 6, internal production change adjustment is performed. That is, during the production change adjustment period of group 6, internal production change adjustment for the production of group 6 is performed for the component supply unit 6 of the main body of the component assembly device M4 or M5 used for the production of group 5 and loaded on the production line L2. Therefore, during the production change adjustment period of group 6, the production of production line L1 is sometimes stopped. Such internal production change adjustment of group 6 is performed, for example, when the trolleys 13 are insufficient. That is, when there is no trolley 13 that can be used for the production change adjustment of group 6 except the trolley 13 of the component assembly device M4 or M5 loaded on the production line L2, the production change adjustment of group 6 is performed as internal production change adjustment. Then, if the production change adjustment of group 6 is completed, the production of group 6 is started in production line L1.

[0152] Here, the production progress of one or more mounting substrates executed by the lines L1 and L2 may be ahead of the initial production plan. In such a case, the plan processing unit 103 of the production management device 100 changes the initial production plan based on the progress data sent from the lines L1 and L2.

[0153] For example, Figure 8As shown in (b), the production progress of group 1 and group 2 executed by production line L1 is sometimes earlier than the initial production plan. In such a case, the plan processing unit 103 in this embodiment determines whether the internal production change adjustment shown in the initial production change adjustment plan can be changed to an external production change adjustment. Specifically, as described below.

[0154] The planning processing unit 103 acquires progress data from the production line L1 via the acquiring unit 108 at the processing time of the production of the group 1 or the group 2. The planning processing unit 103 determines whether the production progress at the processing time is ahead of the initial production plan based on the progress data.

[0155] Then, if the planning processing unit 103 determines that the production progress is ahead of the initial production plan, it changes the initial operation plan of the production line L1 included in the initial production plan according to the progress data. That is, the planning processing unit 103 changes the production completion time of the group 2 of the production line L1 from the time t13 to the time t11. For example, the planning processing unit 103 calculates the production time of the remaining one or more unproduced mounting substrates included in the group 2 based on the number of mounting substrates produced by the group 2 indicated by the progress data after the start of the production of the group 2 and the production time of each mounting substrate. Then, the planning processing unit 103 adds the calculated production time to the processing time, thereby calculating the production completion time t11 of the group 2.

[0156] Furthermore, when the plan processing unit 103 determines that the production progress is ahead of the initial production plan, it determines whether the subsequent production adjustment scheduled to be later than the processing time in the initial production adjustment plan is an internal production adjustment. Figure 8 In the example shown in (b), the planning processing unit 103 determines that the production change adjustment of the group 6 as the subsequent production change adjustment is an internal production change adjustment.

[0157] Then, if the subsequent production change adjustment is an internal production change adjustment, the planning processing unit 103 calculates the time when the internal production change adjustment is completed based on the production progress at the processing time, that is, the internal production change adjustment completion time when the production change adjustment of group 6 is completed. Figure 8 In the example shown, the production progress of group 4 and group 5 executed by production line L2 is carried out as per the initial production plan. Therefore, the planning processing unit 103 calculates the internal production changeover completion time as time t14 as per the initial production plan.

[0158] Furthermore, when the subsequent production change adjustment is changed from internal production change adjustment to external production change adjustment, the planning processing unit 103 calculates the time when the external production change adjustment is completed, that is, the external production change adjustment completion time, based on the production progress at the processing time. Figure 8In the example shown, the production completion time of group 2 is changed from time t13 to time t11, so the planning processing unit 103 determines that the component supply unit 6 used for the production of group 2 can be used for the external production change adjustment of group 6. Therefore, the planning processing unit 103 adds the time required for the external production change adjustment of group 6 to the production completion time t11 of group 2 calculated based on the production progress at the processing time, thereby calculating the external production change adjustment completion time t12. The time required for the external production change adjustment of group 6 is, for example, the sum of the conveyance time of the trolley 13 of the component supply unit 6 and the feeder preparation time required for replacement, unloading, loading, etc. of the feeder 7 of the trolley 13. The conveyance time and the feeder preparation time of each feeder 7 can also be saved in advance in the setting data holding unit DB2, for example.

[0159] Then, the plan processing unit 103 changes the subsequent production change indicated by the initial production change adjustment plan from internal production change adjustment to external production change adjustment based on the initial production plan, the internal production change adjustment completion time t14 and the external production change adjustment completion time t12, thereby creating a production change adjustment plan.

[0160] For example, the plan processing unit 103 determines whether the internal production change adjustment completion time t14 is later than the external production change adjustment completion time t12. Then, if the internal production change adjustment completion time t14 is later than the external production change adjustment completion time t12, the plan processing unit 103 changes the production change adjustment of the group 6 as the subsequent production change adjustment from the internal production change adjustment to the external production change adjustment.

[0161] Thus, in the present embodiment, when the production progress is ahead of the initial production plan, that is, when the production progress is early, the subsequent production change adjustment included in the initial production change adjustment plan is changed from the internal production change adjustment to the external production change adjustment. In addition, this change is made based on the initial production plan, the internal production change adjustment completion time t14, and the external production change adjustment completion time t12, so that a production change adjustment plan that further improves production efficiency relative to the advanced production progress can be created. In other words, the non-operation period of the production line L2 for the internal production change adjustment scheduled in the initial production plan can be saved. In addition, the completion time of the subsequent production change adjustment can be advanced, and production efficiency can be improved.

[0162] For example, when production progress is ahead of the production plan, the cart 13 of the component supply unit 6 loaded on the component assembly device M4 or M5 of the production system 1 can be returned to the production change adjustment area earlier than originally planned. At this time, depending on the production progress, there is a case where the internal production change adjustment planned in the initial production plan can be changed to an external production change adjustment. By changing the internal production change adjustment with the operation loss of the component assembly device M4 or M5 to the external production change adjustment without the operation loss, the operation loss of the component assembly device M4 or M5 can be reduced.

[0163] Here, even if the internal production change adjustment completion time t14 is later than the external production change adjustment completion time t12, the planning processing unit 103 may not change the production change adjustment of the group 6 when the production completion time indicated in the initial production plan is delayed. On the other hand, when the production completion time is not delayed, the planning processing unit 103 may change the production change adjustment of the group 6 as described above.

[0164] Specifically, in Figure 8 In the initial production plan shown in (a), the component supply unit 6 used for the production of group 2 is used for the external production adjustment of group 7. However, if Figure 8 As shown in (b), if the production changeover of group 6 is changed from internal production changeover to external production changeover, the component supply unit 6 used for the production of group 2 is used for the external production changeover of group 6. That is, for the external production changeover of group 7, the component supply unit 6 originally planned cannot be used, that is, the component supply unit 6 used for the production of group 2 cannot be used. As a result, the production completion time in the production line L1 may be delayed.

[0165] Therefore, if Figure 8 As shown in (b), the planning processing unit 103 searches for the component supply unit 6 that can be used for the external production change adjustment of the group 7. Then, the planning processing unit 103 finds the component supply unit 6 used for the production of the group 5 performed by the production line L2 as the component supply unit 6 that can be used for the external production change adjustment of the group 7.

[0166] Next, the planning processing unit 103 calculates the production completion time of group 7 when the component supply unit 6 used for the production of group 5 is used for the external production adjustment of group 7. Figure 8In the case shown in (b), even if the production change adjustment of group 6 is changed, the production change adjustment of group 7 will be completed before the production start time of group 7 executed by production line L1 shown in the initial production plan. Therefore, the planning processing unit 103 calculates the original time of the plan, that is, the time shown in the initial production plan, as the production completion time of the above-mentioned group 7. As a result, even if the production change adjustment of group 6 is changed, the planning processing unit 103 will determine that the production completion time of group 7 executed by production line L1 is not delayed than the originally scheduled production completion time in the initial production plan. Therefore, the planning processing unit 103 changes the production change adjustment of group 6 from internal production change adjustment to external production change adjustment.

[0167] In this way, the plan processing unit 103 in this embodiment determines whether the production completion time of the plurality of mounting substrates included in the initial production plan is delayed due to, for example, the production change adjustment of the group 6, that is, the change of the subsequent production change adjustment. Then, if the production completion time is not delayed, the plan processing unit 103 changes the subsequent production change adjustment from the internal production change adjustment to the external production change adjustment. In this way, the delay of the production completion time of the plurality of mounting substrates caused by the change of the subsequent production change adjustment can be suppressed.

[0168] In addition, as described above, the plan processing unit 103 in this embodiment determines whether the production completion time is delayed from the initial production plan, but such a determination may not be performed. That is, when the internal production change adjustment completion time t14 is later than the external production change adjustment completion time t12, the plan processing unit 103 may change the subsequent production change adjustment from the internal production change adjustment to the external production change adjustment regardless of the delay in the production completion time.

[0169] [Overall processing flow]

[0170] Fig. 9 This is a flowchart showing an example of overall processing of the production management device 100 .

[0171] The production management device 100 transmits production data to the production lines L1 and L2 respectively, thereby causing the production lines L1 and L2 to start production based on the initial production plan indicated by the production data (step S1 ).

[0172] Next, the acquisition unit 10g of the production management device 100 acquires progress data from each of the production lines L1 and L2 (step S2).

[0173] Then, the planning processing unit 103 of the production management device 100 determines whether the production progress represented by the progress data of the production lines L1 and L2 obtained in step S2 deviates from the initial production plan (step S3). Here, if the planning processing unit 103 determines that the production progress deviates from the initial production plan ("Yes" in step S3), Figures 5 to 8 On the other hand, if the plan processing unit 103 determines that the production progress has not deviated from the initial production plan ("No" in step S3), the plan change processing in step S4 is not executed.

[0174] Next, the planning processing unit 103 waits for a given time (step S5). For example, the given time may be 10 minutes, or 20 minutes, or may be the sending cycle of the progress data sent from the production lines L1 and L2. Then, the control unit 101 of the production management device 100 determines whether the production performed by the production lines L1 and L2 respectively has been completed (step S6). Here, if the control unit 101 determines that the production is not completed ("No" in step S6), the acquisition unit 108 and the planning processing unit 103 are caused to repeatedly perform the processing starting from step S2. In addition, when repeatedly performing the processing of step S3, if the initial production plan is changed, then in this step S3, it is determined whether the production progress deviates from the production plan that is the changed initial production plan. That is, when steps S3 to S5 are repeatedly performed, Figures 5 to 8 The initial production plan shown is replaced by the production plan before the change. In addition, hereinafter, the initial production plan and the production plan before the change are simply referred to as production plans.

[0175] On the other hand, when the control unit 101 determines that the production is completed (YES in step S6 ), it ends the processing related to the production plan.

[0176] [Plan change processing flow]

[0177] Fig.10 1 is a flowchart showing an example of the plan change processing performed by the plan processing unit 103. Fig.10 It is shown in detail Fig. 9 Flowchart of the processing of step S4 in .

[0178] First, the planning processing unit 103 determines whether the production progress is earlier than or ahead of the production plan (step S41). Here, if the planning processing unit 103 determines that the production progress is earlier than or ahead of the production plan ("Yes" in step S41), Figure 8 As in the example of , the change process from internal production change adjustment to external production change adjustment is performed (step S42).

[0179] On the other hand, if the planning processing unit 103 determines that the production progress is later than the production plan ("No" in step S41), it determines whether the subsequent production adjustment, which is scheduled to be processed later than the current time, is an external production adjustment of the group including the first product (step S43). Figure 5In the case of the example, the planning processing unit 103 determines that the subsequent production change adjustment is an external production change adjustment of the group 2 including the product D as the first product.

[0180] Then, if the planning processing unit 103 determines that the subsequent production change adjustment is an external production change adjustment of a group including the first variety ("Yes" in step S43), it further determines whether the completion of the external production change adjustment of the group is later than the start of production of the first variety (step S44). Figure 5 In the example of , the plan processing unit 103 determines whether the completion time t4 of the external production changeover adjustment of the group 2 becomes later than the production start time t3 of the mounting substrate of the group 2 included in the initial production plan.

[0181] Here, if the planning processing unit 103 determines that the completion of the external production change adjustment of the group is later than the start of production of the first variety ("Yes" in step S44), the production change adjustment of at least one variety in the group is changed from external production change adjustment to internal production change adjustment (step S45). In other words, the planning processing unit 103 maintains the production change adjustment of the first variety in the group as external production change adjustment, and changes the production change adjustment of at least the last variety in the group from external production change adjustment to internal production change adjustment. Figure 5 In the example of , the planning processing unit 103 maintains the production change adjustment for variety D included in group 2 as external production change adjustment, and changes the production change adjustment for variety E and variety F included in group 2 from external production change adjustment to internal production change adjustment.

[0182] Then, the planning processing unit 103 determines whether the external production change adjustment completion time of the first product is later than the previous production completion time (step S46). The previous production completion time is the time when the production of the previous product that was carried out before the production of the first product was completed. Figure 6 In the case of example (a), the planning processing unit 103 determines that the external production adjustment completion time t5 of the first product D is completed after the previous production completion time t3. The previous production completion time t3 is the time when the production of group 1 is completed before the production of group 2.

[0183] Here, if the planning processing unit 103 determines that the external production change adjustment completion time of the first product is later than the previous production completion time ("Yes" in step S46), Figure 6 The production change adjustment and re-change processing within the group is performed as in the example (b) (step S47).

[0184] [Change process from internal production change adjustment to external production change adjustment]

[0185] Fig.111 is a flowchart showing an example of a change process from internal production change adjustment to external production change adjustment performed by the planning processing unit 103. Fig.11 It is shown in detail Fig.10 Flowchart of the processing of step S42 in .

[0186] First, the plan processing unit 103 determines whether there is an internal production change adjustment in the production change adjustment plan that is later than the processing time (step S421). In addition, when the plan change processing is initially performed, the production change adjustment plan is the initial production change adjustment plan. That is, the plan processing unit 103 determines whether the production change adjustment scheduled to be later than the processing time in the initial production change adjustment plan, i.e., the subsequent production change adjustment, is an internal production change adjustment. Figure 8 In the example of (a), the planning processing unit 103 determines that the production change adjustment of the group 6 as the subsequent production change adjustment is an internal production change adjustment.

[0187] Here, if the planning processing unit 103 determines that there is an internal production change adjustment ("Yes" in step S421), it calculates the time when the internal production change adjustment is completed based on the production progress, that is, the internal production change adjustment completion time (step S422). Figure 8 In the example of , the planning processing unit 103 calculates the internal production change adjustment completion time t14 of the group 6.

[0188] Furthermore, when the internal production change adjustment is changed to an external production change adjustment, the planning processing unit 103 calculates the time when the external production change adjustment is completed based on the production progress, that is, the external production change adjustment completion time (step S423). Figure 8 In the example of , the planning processing unit 103 calculates the external production changeover adjustment completion time t12 of the group 6.

[0189] Then, the planning processing unit 103 determines whether the completion time of the external production change adjustment calculated in step S423 is earlier than the completion time of the internal production change adjustment calculated in step S422 (step S424). In other words, the planning processing unit 103 determines whether the completion time of the internal production change adjustment calculated in step S422 is later than the completion time of the external production change adjustment calculated in step S423. Here, if the planning processing unit 103 determines that the completion time of the external production change adjustment is earlier than the completion time of the internal production change adjustment ("Yes" in step S424), it further determines whether the production completion time is delayed due to changes in subsequent production change adjustments (step S425). Figure 8 In the case of the example, the planning processing unit 103 determines whether the production completion time of group 7 is delayed due to the change of production adjustment of group 6.

[0190] Here, if the planning processing unit 103 determines that the production completion time is not delayed (“No” in step S425), for example Figure 8The production change adjustment of group 6 shown, that is, the subsequent production change adjustment, is changed from internal production change adjustment to external production change adjustment (step S426).

[0191] In addition, if it is determined in step S421 that there is no internal production change adjustment, if it is determined in step S424 that the completion time of the external production change adjustment is not earlier than the completion time of the internal production change adjustment, and if it is determined in step S425 that the production completion time is delayed, no subsequent production change adjustment is performed.

[0192] In addition, Fig.11 In the example shown, although step S425 is included in the change process from internal production change adjustment to external production change adjustment, it may not be included. In this case, when it is determined in step S424 that the external production change adjustment completion time is earlier than the internal production change adjustment completion time ("Yes" in step S424), the process of step S426 is performed.

[0193] [Production adjustment and re-change processing flow]

[0194] Fig.12 1 is a flowchart showing an example of the production change adjustment and re-change processing performed by the planning processing unit 103. Fig.12 It is shown in detail Fig.10 Flowchart of the processing of step S47 in .

[0195] First, the plan processing unit 103 determines Fig.10 In steps S43 to S46, it is determined whether there is a second variety in the group including the first variety that can be adjusted for external production in a shorter time than the first variety (step S471). Figure 6 In the example of , the planning processing unit 103 determines whether there is a second variety that takes a shorter time than variety D for external production changeover adjustment among the remaining varieties E and F except for variety D which is the first variety.

[0196] Here, if the planning processing unit 103 determines that there is a second type ("Yes" in step S471), the production order of the first type and the second type is switched (step S472). Figure 6 In the example of (b), the planning processing unit 103 switches the production order of the first variety D and the second variety E. Then, the planning processing unit 103 changes the external production change adjustment of the first variety to the internal production change adjustment (step S473), and changes the internal production change adjustment of the second variety to the external production change adjustment (step S474).

[0197] As described above, in the production management device 100 of the present embodiment, a production change adjustment plan indicating whether the production change adjustment of each of the one or more component supply units 6 is an internal production change adjustment or an external production change adjustment is created based on the production progress in the production system 1. Therefore, whether the production progress in the production system 1 is later than the production plan or earlier than the production plan, an appropriate production change adjustment plan corresponding to the production progress can be created. In other words, the production change adjustment can be appropriately managed.

[0198] (Other Modifications)

[0199] The above is a description of a production management device and a production management method involving one or more embodiments based on an embodiment, but the present disclosure is not limited to the embodiment. As long as it does not depart from the main purpose of the present disclosure, the products obtained by implementing various modifications that a person skilled in the art can also be included in the scope of the present disclosure.

[0200] In addition, in the above-mentioned embodiment Figures 5 to 8 In the example of , an example of changing the initial production plan including the initial operation plan and the initial production change adjustment plan is shown, but the same change as the example of changing the initial production plan can also be made from the production plan that is the changed initial production plan.

[0201] In addition, in the above-mentioned embodiment, there are cases where the production change adjustment is changed from the external production change adjustment to the internal production change adjustment and cases where the production change adjustment is changed from the internal production change adjustment to the external production change adjustment. In the internal production change adjustment, the trolley 13 is loaded on the component assembly device M4 or M5, so the feeder preparation time spent on the replacement, unloading, loading, etc. of the feeder 7 may become longer than the external production change adjustment. In addition, in the internal production change adjustment, the content of the internal production change adjustment is limited, for example, whether to stop the production of the component assembly device M4 or M5 having the component supply unit 6 for the internal production change adjustment. For example, in the internal production change adjustment, it is sometimes limited to the loading of the feeder 7. On the other hand, in the external production change adjustment, it is necessary to unload the component supply unit 6, that is, the trolley 13 from the component assembly device M4 or M5 and transport it to the place where the production change adjustment is performed. Then, it is necessary to transport and load the trolley 13 that has undergone the production change adjustment to the component assembly device M4 or M5. Therefore, the production efficiency of either the internal production change adjustment or the external production change adjustment is not always high, and the type of production change adjustment with high production efficiency varies depending on the production conditions. For example, when all the feeders 7 of the trolley 13 need to be replaced, the production efficiency of the external production change adjustment is higher than that of the internal production change adjustment. If the number of feeders 7 loaded on the trolley 13 is small, the production efficiency of the internal production change adjustment is higher than that of the external production change adjustment. In the above embodiment, the type of production change adjustment with high production efficiency can be selected according to the above production conditions that change over time.

[0202] In addition, in the above-mentioned embodiment, the display unit 106 of the production management device 100 displays the production plan including the operation plan and the production change adjustment plan, but the production plan may also be displayed by the display unit 213 of each of the production lines L1 and L2.

The production management method also includes: Determining whether the production progress is ahead of the production plan at the processing time; In the case where the production progress is ahead of the production plan, determining whether the production change adjustment scheduled to be later than the processing time in the initial production change adjustment plan, i.e., the subsequent production change adjustment, is the internal production change adjustment; In a case where the subsequent production change adjustment is the internal production change adjustment, calculating the time when the internal production change adjustment is completed, that is, the internal production change adjustment completion time, based on the production progress at the processing time; and When the subsequent production change adjustment is changed from the internal production change adjustment to the external production change adjustment, the time when the external production change adjustment is completed, that is, the external production change adjustment completion time, is calculated based on the production progress at the processing time. In the creation of the production changeover adjustment plan, The subsequent production change adjustment represented by the initial production change adjustment plan is changed from the internal production change adjustment to the external production change adjustment based on the production plan, the internal production change adjustment completion time, and the external production change adjustment completion time, thereby creating the production change adjustment plan.

10. The production management method according to claim 9, wherein: In the creation of the production changeover adjustment plan, Determine whether the internal production change adjustment completion time is later than the external production change adjustment completion time, When the internal product change adjustment completion time is later than the external product change adjustment completion time, the subsequent product change adjustment is changed from the internal product change adjustment to the external product change adjustment.

11. The production management method according to claim 9, wherein: In the creation of the production changeover adjustment plan, determining whether the production completion time of the plurality of mounting substrates is delayed from the production plan due to the change of the subsequent production change adjustment, When the production completion time is not delayed, the subsequent production change adjustment is changed from the internal production change adjustment to the external production change adjustment.

12. The production management method according to claim 9, wherein: In the case where the subsequent production changeover is the external production changeover performed on a group basis on a component supply unit in order to produce mounting substrates for each of a plurality of items included in the group, The production management method also includes: determining whether the production progress at the processing time is later than the production plan; and In a case where the production progress is later than the production plan, it is determined whether the completion time of the external production change adjustment in units of groups becomes later than the production start time of the mounting substrate of the group included in the production plan, In the creation of the production changeover adjustment plan, When it is determined that the completion time of the external production change adjustment based on the group becomes after the production start time, the production change adjustment for at least one variety included in the group is maintained as the external production change adjustment, and the production change adjustment for at least one other variety included in the group is changed from the external production change adjustment to the internal production change adjustment, thereby creating the production change adjustment plan.

13. The production management method according to claim 12, wherein: In the creation of the production changeover adjustment plan, The production change adjustment for the variety of mounting substrates produced initially in the group, i.e., variety 1, is maintained as the external production change adjustment, and the production change adjustment for each of at least one remaining variety included in the group except the variety 1 is changed from the external production change adjustment to the internal production change adjustment, thereby creating the production change adjustment plan.

14. The production management method according to claim 13, wherein: The production management method also includes: Determining whether, in the created production change adjustment plan, the external production change adjustment completion time of the first product is later than the previous production completion time of the mounting substrate production completed before the group production; When it is determined that the external production change adjustment completion time is later than the previous production completion time, determining whether there is a second variety among the remaining at least one variety other than the first variety for which the external production change adjustment takes a shorter time than the first variety; and When it is determined that the second variety exists, the production order of the first variety and the second variety is swapped, the production change adjustment of the first variety is changed from the external production change adjustment to the internal production change adjustment, and the production change adjustment of the second variety is changed from the internal production change adjustment to the external production change adjustment, thereby updating the created production change adjustment plan.

15. The production management method according to claim 12, wherein: The external production change adjustment based on groups includes: production change adjustment of at least one component commonly used in the production of multiple varieties included in the group, that is, public production change adjustment.

16. The production management method according to any one of claims 9 to 15, wherein: The production management method also includes: The created production change adjustment plan is displayed.
