Japanese Patent Application Laid-Open No. 2020-129161

In machining systems, it is desirable to manage workpiece machining schedules. In machining systems, workers perform a variety of tasks. For example, workers replenish the machining system with resources consumed in workpiece machining.

If resource replenishment for a machining system is delayed, workpiece processing will come to a halt. As a result, workpiece production plans may fall behind schedule. Therefore, there is a need for technology that can provide advance warning of resource shortages in machining systems.

One example of the present disclosure provides a management device for managing processing schedules for multiple processing systems. The management device includes a control unit. The control unit performs the following processes: acquires resource information that specifies, for each of the multiple processing systems, the remaining amount of resources required to process workpieces; when receiving input of a production plan that specifies at least the type of workpiece to be produced and the quantity of the workpieces to be produced, allocates the processing of the quantity of the workpieces to the multiple processing systems and sends a processing order to the destination processing system that indicates the type of workpiece to be processed and the quantity of the workpieces; and determines, based on the remaining amount of the resource in the destination processing system and the processing order, whether the resource will be insufficient in the destination processing system; and, if it is determined that the resource will be insufficient, outputs a warning indicating the resource will be insufficient.

In one example of the present disclosure, the sending process is performed before the output process.

In one example of the present disclosure, the warning includes at least an identifier indicating the processing system in which the resource shortage will occur and the expected time when the resource shortage will occur.

In one example of the present disclosure, the resources include at least one of a tool used to machine a workpiece, a raw workpiece before machining, and a coolant that is dispensed onto the workpiece during machining.

In one example of the present disclosure, the multiple processing systems include a first processing system that processes a first workpiece but not a second workpiece, and a second processing system that processes the first workpiece and the second workpiece. The resource information defines at least a first remaining amount of a resource held by the first processing system that is consumed when processing the first workpiece, and a second remaining amount of a resource held by the second processing system that is consumed when processing the first workpiece. The production plan includes the quantity of the first workpieces and the quantity of the second workpieces. If the first remaining amount and the second remaining amount are depleted in the process of processing the quantity of the first workpieces defined in the production plan, the control unit outputs the warning for the first processing system that is not responsible for processing the second workpiece.

Another example of the present disclosure provides a management system for managing processing schedules for multiple processing systems. The management system includes a management device and multiple processing systems capable of communicating with the management device. The management device performs the following processes: acquires resource information that specifies, for each of the multiple processing systems, the remaining amount of resources required to process workpieces; when receiving input of a production plan that specifies at least the type of workpiece to be produced and the quantity of the workpieces to be produced, allocates the processing of the quantity of the workpieces to the multiple processing systems and sends a processing order to the destination processing system that indicates the type of workpiece to be processed and the quantity of the workpieces; and determines, based on the remaining amount of the resource in the destination processing system and the processing order, whether the resource will be insufficient in the destination processing system; and, if it is determined that the resource will be insufficient, outputs a warning indicating the resource will be insufficient.

Another example of the present disclosure provides a management method for managing processing schedules in multiple processing systems. The management method includes the steps of: acquiring resource information that specifies, for each of the multiple processing systems, the remaining amount of resources required to process workpieces; when receiving input of a production plan that specifies at least the type of workpiece to be produced and the quantity of the workpieces to be produced, allocating the processing of the quantity of the workpieces to the multiple processing systems and sending a processing order that indicates the type of workpiece to be processed and the quantity of the workpieces to be processed to the processing destination processing system; and determining, based on the remaining amount of the resource in the processing destination processing system and the processing order, whether the resource will be insufficient in the processing destination processing system; and, if it is determined that the resource will be insufficient, outputting a warning indicating the resource will be insufficient.

In another example of the present disclosure, a management program for managing processing schedules in multiple processing systems is provided. The management program causes a computer to perform the following processes: acquire resource information that specifies, for each of the multiple processing systems, the remaining amount of resources required to process workpieces; when receiving input of a production plan that specifies at least the type of workpiece to be produced and the quantity of the workpieces to be produced, allocate the processing of the quantity of the workpieces to the multiple processing systems and send a processing order specifying the type of workpiece to be processed and the quantity of the workpieces to be processed to the processing destination processing system; and determine, based on the remaining amount of the resource in the processing destination processing system and the processing order, whether the resource will be insufficient in the processing destination processing system, and, if it is determined that the resource will be insufficient, output a warning indicating the resource will be insufficient.

Embodiments of the present invention will now be described with reference to the drawings. In the following description, identical parts and components are designated by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of these will not be repeated. Note that the embodiments and variations described below may be selectively combined as appropriate.

<A. Management System 5>
First, the device configuration of the management system 5 will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the management system 5.

As shown in FIG. 1, the management system 5 includes an information processing device 10, a management device 100, a processing system 200, and a user terminal 300.

The information processing device 10 is, for example, a notebook or desktop PC (Personal Computer), a tablet terminal, or other computer with communication capabilities.

Note that although the example in Figure 1 shows one information processing device 10, the number of information processing devices 10 that make up the management system 5 may be two or more.

The management device 100 is configured to be able to communicate with the information processing device 10 via the network NW1. The management device 100 is, for example, a notebook or desktop PC, a tablet device, a smartphone, a wearable device, or any other computer with communication capabilities.

The management device 100 is configured to be able to communicate with the processing system 200 via network NW2. Network NW2 may be a different network from network NW1, or may be the same network as network NW1.

The management device 100 may be, for example, a notebook or desktop PC, a tablet device, a smartphone, a wearable device, or any other computer with communication capabilities.

Note that although the example in Figure 1 shows one management device 100, the number of management devices 100 that make up the management system 5 may be two or more.

The machining system 200 is configured to be able to communicate with the management device 100 via the network NW2. The machining system 200 is a system capable of machining workpieces. The machining system 200 includes at least one machine tool. The machining system 200 may also include a workpiece transport robot, a cleaning machine, etc. Specific examples of the machining system 200 will be described later.

The processing system 200 is configured to be able to communicate with the management device 100 via network NW2. Network NW2 may be a different network from network NW1, or may be the same network as network NW1.

In addition, in the example of Figure 1, three processing systems 200A to 200C are shown as being managed by the management device 100, but the number of processing systems 200 that make up the management system 5 may be one, or two or more.

Hereinafter, when no particular distinction is made between the processing systems 200A to 200C, the processing systems 200A to 200C will also be referred to as processing system 200.

The machining system 200 is a system equipped with the function of machining a workpiece. There are no particular limitations on the devices that make up the machining system 200. In the example of Figure 1, the machining systems 200A and 200B each include a controller, a machine tool, a robot, and a washer. The machining system 200C includes a machine tool.

The controllers provided in the machining systems 200A and 200B control the subordinate equipment, such as machine tools, robots, and cleaning machines. The controllers periodically send information such as the status of each subordinate device to the management device 100.

The user terminal 300 may be, for example, a notebook or desktop PC, a tablet device, a smartphone, a wearable device, or any other computer with communication capabilities.

The user terminal 300 is configured to be able to communicate with the management device 100 and the processing system 200 via the network NW2. As an example, a worker can access the management device 100 via the user terminal 300 and check the progress status of the processing system 200.

The number of user terminals 300 constituting the management system 5 may be one or more. The number of user terminals 300 used depends on the number of managers and workers, for example.

<B. Machining System 200>
Next, an example of the processing system 200 shown in Fig. 1 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a diagram showing the processing system 200 as an example.

As shown in FIG. 2, the processing system 200 includes one or more storage sections 220, one or more transport devices 230, one or more machine tools 240, and one or more work stations 250.

The storage unit 220 is one of the destinations for the pallet PT by the transport device 230, and is a place for storing the pallet PT. A pallet PT is a platform on which a workpiece to be machined is fixed. The storage unit 220 can store multiple pallets PT. The storage unit 220 stores empty pallets PT before a workpiece is attached, pallets PT on which a workpiece is attached before being machined, pallets PT on which a workpiece in the middle of being machined is attached, and pallets PT on which a workpiece that has completed machining is attached.

The transport device 230 transports a specified pallet PT to a specified location. More specifically, the transport device 230 includes rails 232 and a dolly 234. The dolly 234 has a fork unit 236 that is configured to be driven in a direction perpendicular to the rails 232 (i.e., a direction perpendicular to the traveling direction of the dolly 234). The dolly 234 is configured to be movable along the rails 232 by a drive mechanism such as a servo motor. The dolly 234 moves along the rails 232 to the position of the pallet PT to be transported, and uses the fork unit 236 to place the pallet PT to be transported onto the dolly 234. The dolly 234 then moves along the rails 232 to the specified destination, and uses the fork unit 236 to deliver the pallet PT to the destination.

Note that while the example in Figure 2 shows a transport device 230 that moves on rails 232, examples of the transport device 230 are not limited to this. As an example, the transport device 230 may be a two- to three-axis driven Cartesian robot (autoloader), a four- to seven-axis driven articulated robot, or a self-propelled robot.

The machine tool 240 is one of the destinations to which the pallet PT is transported by the transport device 230. The machine tool 240 processes the workpiece attached to the transported pallet PT according to a pre-designed machining program. Once the workpiece machining is complete, the pallet PT in the machine tool 240 is transported by the transport device 230 to the storage section 220 or the work station 250.

Note that while the example in Figure 2 shows the machining system 200 being composed of one machine tool 240, the machining system 200 may also be composed of multiple machine tools 240.

Work station 250 is one of the destinations to which pallets PT are transported by transport device 230. At work station 250, workers perform various tasks on the pallets PT that have been brought in so as not to interrupt processing in processing system 200.

As one example, a worker attaches the workpiece to be processed to the loaded pallet PT at work station 250. As another example, the worker changes the attachment position of the workpiece on the pallet PT, or removes the workpiece from the pallet PT after processing has been completed. As yet another example, once the worker has completed work on the pallet PT, the worker performs an operation on a terminal (not shown) in work station 250 to indicate that the work is complete.

As another example, a worker performs the task of replenishing the machining system 200 with resources required for machining the workpiece. A resource is, for example, an object consumed by machining the workpiece on the machine tool 240.

One example of a resource consumed in machining a workpiece is the tools used to machine the workpiece. Tools wear out as the workpiece is machined. As a result, workers must replace old tools that have reached the end of their lifespan with new tools.

Another example of a resource consumed by processing a workpiece is raw material workpieces. Raw material workpieces are the raw materials from which product workpieces are made. Workers must replenish the processing system 200 with the raw material workpieces needed to produce the product workpieces.

Another example of a resource consumed by machining a workpiece is coolant. When machine tool 240 machines a workpiece, heat is generated. To reduce this heat generation, machine tool 240 sprays coolant onto the workpiece. The coolant sprayed onto the workpiece evaporates, so the coolant inside machine tool 240 gradually decreases. Therefore, the operator needs to replenish coolant in machine tool 240.

Note that "resources" as used in this specification are not limited to objects consumed in the machining of workpieces. Resources are a concept that includes various objects necessary for the machining of workpieces. Resources can include not only tools, raw workpieces, and coolant, but also the above-mentioned pallets PT.

<C. Sequence Flow>
If the resource replenishment work for the machining system 200 is delayed, the machining of the workpieces will come to a halt. As a result, the workpiece production plan may fall behind schedule. Therefore, the management system 5 notifies the worker of a resource shortage in the machining system 200. This allows the worker to replenish the machining system 200 with new resources before the resources run out. As a result, the workpiece production plan proceeds as scheduled.

The following provides an overview of the resource shortage warning function, with reference to Figures 3 and 4. Figure 3 is a diagram showing an example of the data flow between the information processing device 10, the management device 100, the processing system 200, and the user terminal 300.

In step S10, the manager inputs a work production plan via the information processing device 10. The production plan includes at least the type of work to be produced and the quantity of work to be produced. The information processing device 10 transmits the production plan input by the manager to the management device 100.

In step S12, the management device 100 receives resource information from each of the processing systems 200 under management based on receiving the production plan from the information processing device 10. The resource information is data that includes at least the resources held by the processing system 200 and the remaining amount of those resources. Specific examples of resource information will be described later. In the example of Figure 3, the management device 100 receives resource information from each of the processing systems 200A and 200B.

In step S20, the management device 100 allocates processing tasks for the quantity of workpieces specified in the production plan to the processing systems 200A and 200B. As an example, the management device 100 preferentially allocates processing tasks to the processing system 200 that has sufficient resources required to produce that quantity of workpieces. Next, the management device 100 generates processing orders for each allocated processing task. The processing order specifies, for example, the type of workpiece to be processed and the quantity of that workpiece. Note that the information specified in the processing order is not limited to this and may also include the time to start processing the workpieces, etc.

In step S22, the management device 100 transmits the processing order generated in step S20 to the processing system 200. Upon receiving the processing order, the processing system 200 processes the workpiece in accordance with the processing order.

In step S30, the management device 100 determines whether the destination processing system 200 is short of resources based on the remaining resources in the destination processing system 200 and the processing order generated in step S20.

In step S32, if the management device 100 determines that there will be a resource shortage in the destination processing system 200, it outputs a warning indicating the resource shortage in association with the processing schedule related to the production plan. The warning can be output to any destination. In the example of Figure 3, the warning is sent to the user terminal 300.

In step S40, the user terminal 300 displays the warning received from the management device 100. Figure 4 shows an example of an output screen IM1 that warns of a resource shortage.

The output screen IM1 includes a processing schedule SCA related to the production plan input in step S10. The processing schedule SCA is displayed in association with an identifier indicating the processing system 200 at the processing destination. In the example of FIG. 4, this identifier indicates processing system 200A. In addition, in the example of FIG. 4, the processing schedule SCA indicates the time period TA1 during which workers are scheduled to attach workpieces to pallets, and the time period TA2 during which processing system 200A is scheduled to process the workpieces.

The output screen IM1 also includes a resource bar RB. As an example, the resource bar RB indicates a time period TR1 in which resources are sufficient and a time period TR2 in which a resource shortage will occur. The time period TR2 in which a resource shortage will occur is displayed as a warning WR, thereby indicating the time when a resource shortage is expected to occur.

The warning WR is displayed in association with an identifier indicating the processing system 200 in which a resource shortage will occur. "Displayed in an associated state" refers to an output format that allows the user to recognize that the warning WR is linked to the processing system 200 in which a resource shortage will occur. In the example of Figure 4, the warning WR is associated with processing system 200A. This allows the worker to know when resources will run out in processing system 200A, and to replenish new resources in advance. When the worker replenishes resources, the warning WR display disappears.

Preferably, a time bar CT indicating the current time is displayed on the output screen IM1. The time bar CT is configured to be linked to the current time. This allows the worker to recognize how much time they have before a resource shortage occurs.

As described above, the management device 100 sends a processing order to the destination processing system 200 regardless of whether a resource shortage will occur. In other words, the management device 100 executes the processing order transmission process in step S22 before the warning output process in step S32. As a result, the destination processing system 200 will begin processing the workpiece in accordance with the processing order. Therefore, the suspension of processing is postponed as long as possible. On the other hand, by checking the warning WR, the worker can recognize that a resource shortage will occur in the destination processing system 200 while the production plan is proceeding.

<D. Functional configuration of management device 100>
Next, the functional configuration of the management device 100 will be described with reference to Figures 5 to 9. Figure 5 is a diagram showing an example of the functional configuration of the management device 100.

As shown in FIG. 5, the management device 100 includes, as its functional components, a schedule generation unit 152 and an output unit 160. These components will be described in order below.

Note that, although the example in Figure 5 shows an example in which the schedule generation unit 152 and the output unit 160 are implemented in the management device 100, at least one of the schedule generation unit 152 and the output unit 160 may be implemented in another device.

(D1. Schedule Generation Unit 152)
First, the function of the schedule generating unit 152 shown in FIG. 5 will be described with reference to FIGS.

The schedule generation unit 152 generates the processing schedules SCA and SCB shown in FIG. 9 based on the production plan 123 shown in FIG. 6, the work information 124 shown in FIG. 7, and the resource information 125 shown in FIG. 8.

Figure 6 is a diagram showing an example of the data structure of the production plan 123. The production plan 123 is registered by an administrator, for example, in the above-mentioned information processing device 10 or the above-mentioned management device 100. The information registered by the administrator includes, for example, the type of work to be produced and the quantity of work to be produced.

In the example of Figure 6, a production plan PP1 for two workpieces WA and a production plan PP2 for two workpieces WB are registered. Production plan PP1 and production plan PP2 may be registered at the same time or at different times.

Figure 7 shows an example of the data structure of work information 124. Work information 124 specifies the requirements for producing product work.

As an example, work information 124 associates product work information 124A, raw work information 124B, machining program information 124C, machining time information 124D, tool information 124E, mounting time information 124F, and removal time information 124G.

Product work information 124A specifies the type of product work. A product work is a work that is a finished product after processing. The type of product work is specified by an identifier such as the work name or ID (Identification), for example.

Material work information 124B specifies the type of material work required to produce the associated product work. Material work is work before or during processing. The type of material work is specified by an identifier such as the work name or ID. Material work information 124B is registered by a worker, for example, in the above-mentioned management device 100 or the above-mentioned processing system 200.

The machining program information 124C specifies the machining program to be executed when machining the associated material workpiece. The method for generating the machining program is arbitrary. As an example, some machining systems 200 have a function that automatically generates a machining program by having the operator answer questions in an interactive format. The machining program is generated, for example, by this function. Alternatively, the machining program may be designed by the operator writing program code.

Processing time information 124D specifies the time required to process the associated material workpiece. This processing time is, for example, input in advance by the worker. Alternatively, this processing time may be calculated from past processing results for the material workpiece.

Tool information 124E specifies the type of tool used to machine the associated raw workpiece. There may be one or more tools associated with the raw workpiece. The type of tool is specified by an identifier such as the tool name or ID. The type of tool may be entered in advance by the operator, or may be extracted from a description in the machining program.

The mounting time information 124F specifies the time required to mount the associated material workpiece on the pallet. This mounting time is, for example, input in advance by the worker. Alternatively, this mounting time may be calculated from past performance data on the time required to mount the material workpiece on the pallet.

Removal time information 124G specifies the time required to remove a machined workpiece from a pallet. This removal time is input in advance by the worker, for example. Alternatively, the mounting time may be calculated from past performance data on the time required to mount and remove a workpiece from a pallet.

Figure 8 is a diagram showing an example of the data structure of resource information 125. Resource information 125 is information that defines the resources held by the machining system 200 and the remaining amount of those resources for each machining system 200. Resource information 125 includes, for example, tool information 126A, raw workpiece information 126B, and coolant information 126C.

Tool information 126A specifies the type of tool held by machining system 200 and the lifespan of each tool. Tool life is monitored, for example, by machining system 200. More specifically, machining system 200 monitors machining program 422 of machine tool 400 and counts the amount of use of each tool in machine tool 400 from when it was new to the present. "Amount" here is a concept that includes number of times, time, and distance. "Tool usage amount" includes, for example, the total number of times a tool has been used in machining from new to the present, the total time it has been used in machining from new to the present, and the total distance traveled during machining from new to the present.

The machining system 200 reduces the tool's lifespan based on the counted usage. This lifespan is periodically transmitted to the management device 100. The management device 100 updates the tool information 126A specified in the resource information 125 based on the lifespan received from the machining system 200.

Material work information 126B specifies the types of material work held by processing system 200 and the remaining quantity of each material work. The remaining quantity of material work is monitored, for example, by processing system 200. This remaining quantity is periodically transmitted to management device 100. Management device 100 updates material work information 126B specified in resource information 125 based on the remaining quantity received from processing system 200.

The coolant information 126C specifies the remaining amount of coolant held by the machining system 200. The remaining amount of coolant is detected, for example, by a liquid level sensor provided in the machining system 200. The detected remaining amount of coolant is periodically transmitted to the management device 100. The management device 100 updates the material workpiece information 126B specified in the resource information 125 based on the remaining amount received from the machining system 200.

Figure 9 shows an example of processing schedules SCA and SCB generated by the schedule generation unit 152.

The machining schedules SCA and SCB are generated based on the production plans PP1 and PP2 (see Figure 6). More specifically, the schedule generation unit 152 first references the work information 124 to identify the raw workpiece W1 and tool T1 required to produce the workpiece WA specified in the production plan PP1. Next, the schedule generation unit 152 references the resource information 125 to determine the machining system 200A that possesses the identified raw workpiece W1 and tool T1 as the machining destination.

Similarly, the schedule generation unit 152 references the work information 124 to identify the raw workpiece W2 and tool T2 required to produce the workpiece WB specified in the production plan PP2. Next, the schedule generation unit 152 references the resource information 125 to determine the processing destination as the processing system 200A that possesses the identified raw workpiece W2 and tool T2.

The schedule generation unit 152 then references the work information 124 to determine the processing time and work time required to produce the two workpieces WA, and also determines the processing time and work time required to produce the two workpieces WB. The schedule generation unit 152 then generates processing schedules SCA and SCB that enable the two workpieces WA and two workpieces WB to be produced efficiently.

In the example of Figure 9, the processing schedule SCA includes time periods TA1 to TA6. Time periods TA1, TA3, TA4, and TA6 indicate time periods during which workers are scheduled to perform work. Time periods TA2 and TA5 indicate time periods during which processing is scheduled by processing system 200A.

More specifically, time period TA1 indicates the time period during which the worker plans to load the first workpiece WA into location α on the pallet PT. Time period TA2 indicates the time period during which the processing system 200A plans to process the first workpiece WA. Time period TA3 indicates the time period during which the worker plans to remove the first workpiece WA from location α on the pallet PT. Time period TA4 indicates the time period during which the worker plans to load the second workpiece WB into location β on the pallet PT. Time period TA5 indicates the time period during which the processing system 200A plans to process the second workpiece WA. Time period TA6 indicates the time period during which the worker plans to remove the second workpiece WA from location β on the pallet PT.

The processing schedule SCB also includes time periods TB1 to TB6. Time periods TB1, TB3, TB4, and TB6 indicate work time periods by workers. Time periods TB2 and TB5 indicate planned processing time periods by processing system 200A.

More specifically, time period TB1 indicates the time period during which the worker plans to load the first workpiece WB into location α on the pallet PT. Time period TB2 indicates the time period during which the processing system 200A plans to process the first workpiece WB. Time period TB3 indicates the time period during which the worker plans to remove the first workpiece WB from location α on the pallet PT. Time period TB4 indicates the time period during which the worker plans to load the second workpiece WB into location β on the pallet PT. Time period TB5 indicates the time period during which the processing system 200A plans to process the second workpiece WB. Time period TB6 indicates the time period during which the worker plans to remove the second workpiece WB from location β on the pallet PT.

Preferably, the schedule generation unit 152 generates the processing schedules SCA and SCB so that the work times of the workers are continuous. In the example of FIG. 9, the processing schedules SCA and SCB are generated so that the time periods TA3 and TA4 for work on the workpiece WA are continuous with the time period TB1 for work on the workpiece WB. Also, in the example of FIG. 9, the processing schedules SCA and SCB are generated so that the time period TA6 for work on the workpiece WA is continuous with the time periods TB3 and TB4 for work on the workpiece WB. This consolidates the work processes performed by the workers, improving work efficiency.

(D2. Output section 160)
Next, still referring to FIG. 9, the function of the output unit 160 shown in FIG. 5 will be described.

The output unit 160 outputs the processing schedules SCA and SCB generated by the schedule generation unit 152 in various forms.

The screen output destination may be the display of the information processing device 10, the display of the management device 100, the display of the processing system 200, or the display of the user terminal 300.

As another example, the output unit 160 transmits a processing order OD1 related to the processing schedule SCA and a processing order OD2 related to the processing schedule SCB to the processing system 200A at the processing destination.

Note that processing orders OD1 and OD2 only need to specify the type of workpiece to be processed and the quantity of that workpiece, and do not need to be exactly the same as processing schedules SCA and SCB. Preferably, processing orders OD1 and OD2 also specify the start time of processing.

<H. Specific Examples>
Next, a specific example of a case where a warning about a lack of resources is output will be described with reference to FIGS.

Figure 13 is a diagram that shows an overview of the processing in step S101. In step S101, it is assumed that production plan 123A is input to management device 100. Production plan 123A specifies that 30 workpieces WA should be produced.

Based on receiving the production plan 123A, the management device 100 acquires resource information 125 for the subordinate processing system 200. In the example of FIG. 13, resource information 125A related to processing system 200A and resource information 125B related to processing system 200A are shown.

Resource information 125A specifies the types of resources held by machining system 200A and the remaining amounts of those resources. In the example of Figure 13, resource information 125A indicates that machining system 200A holds tools T1 and T2 and raw workpieces W1 and W2.

The remaining amount of resources for tools T1 and T2 is indicated, for example, by the number of times they can be used. In the example of Figure 13, the number of times tool T1 held in machining system 200A can be used is 50. The number of times tool T2 held in machining system 200A can be used is 80.

The remaining amount of resources related to material workpieces W1 and W2 is indicated, for example, by the remaining number. In the example of Figure 13, the remaining amount of material workpieces W1 held in processing system 200A is 150 pieces. The remaining amount of material workpieces W2 held in processing system 200A is 100 pieces.

Resource information 125B specifies the types of resources held by machining system 200B and the remaining amounts of those resources. In the example of Figure 13, resource information 125B indicates that machining system 200B holds tools T1 and T3 and raw workpieces W1 and W3 as resources.

In the example of Figure 13, the remaining number of times that tool T1 held in processing system 200B can be used is 25 times. The remaining number of times that tool T3 held in processing system 200B can be used is 150 times. The remaining number of raw material workpieces W1 held in processing system 200B is 100 pieces. The remaining number of raw material workpieces W3 held in processing system 200B is 200 pieces.

The management device 100 references the above-mentioned work information 124 (see FIG. 7) and identifies the raw workpiece W1 and tool T1 as the resources required to produce the workpiece WA specified in the production plan 123A. Next, the management device 100 calculates the amount of resources required to produce the 30 workpieces WA specified in the production plan 123A. In this example, the required amount of resources is 30 or more times the remaining number of times tool T1 can be used, and 30 or more pieces of raw workpieces W1.

Because the remaining number of times tool T1 held by machining system 200B can be used is fewer than 30 times, management device 100 selects machining system 200A, which has sufficient remaining resources, as the machining destination for workpiece WA. Next, management device 100 generates a machining order ODA to instruct the machining of 30 workpieces WA, and sends this machining order ODA to the machining system 200A that is the machining destination.

The management device 100 then determines whether the processing order ODA will cause a resource shortage. In the example of FIG. 13, the management device 100 predicts that the remaining number of times that tool T1 held in processing system 200A can be used will decrease from 50 to 20, and predicts that the remaining quantity of material workpieces W1 held in processing system 200A will decrease from 150 to 120. In this case, because the remaining quantity of each resource is zero or greater, the management device 100 determines that the processing order ODA will not cause a resource shortage.

Figure 14 is a diagram that outlines the processing in step S102, which follows step S101.

In step S102, it is assumed that production plan 123B is input to management device 100. Production plan 123B specifies that 10 workpieces WB and 50 workpieces WC should be produced.

The management device 100 references the above-mentioned work information 124 and identifies the raw workpiece W2 and tool T2 as the resources required to produce the workpiece WB specified in the production plan 123B. Next, the management device 100 calculates the amount of resources required to produce 10 workpieces WB. In this example, the amount of resources required is 10 or more times for the remaining number of uses of tool T2 and 10 or more for the number of raw workpieces W2.

Since processing system 200B does not have the resources necessary to process workpiece WB, management device 100 determines that processing system 200A, which has the resources necessary to process workpiece WB, will be the processing destination for workpiece WB. Management device 100 then generates a processing order ODB to instruct the processing of 10 workpieces WA and sends this processing order ODB to processing system 200A.

The management device 100 then determines whether a resource shortage will occur based on the processing order ODB. In the example of Figure 14, the management device 100 predicts that the remaining number of times tool T2 held in processing system 200A can be used will decrease from 80 to 70, and predicts that the remaining quantity of raw material workpieces W2 held in processing system 200A will decrease from 100 to 90. In this case, because the remaining quantity of each resource is zero or greater, the management device 100 determines that a resource shortage will not occur based on the processing order ODB.

Furthermore, the management device 100 references the above-mentioned work information 124 and identifies the raw workpiece W3 and tool T3 as the resources required to produce the workpiece WC specified in the production plan 123B. Next, the management device 100 calculates the amount of resources required to produce 50 workpieces WC. In this example, the amount of resources required is 50 or more times for the remaining number of uses of tool T3, and 50 or more for the number of raw workpieces W3.

Since processing system 200A does not have the resources necessary to process the workpieces WC, management device 100 determines that processing system 200B will be the processing destination for the workpieces WC. Management device 100 then generates a processing order ODC to instruct the processing of 50 workpieces WC and sends this processing order ODC to processing system 200B.

The management device 100 then determines whether the processing order ODC will cause a resource shortage. In the example of Figure 14, the management device 100 predicts that the remaining number of times tool T3 held in processing system 200B can be used will decrease from 150 to 100, and predicts that the remaining quantity of material workpieces W3 held in processing system 200B will decrease from 200 to 150. In this case, because the remaining quantity of each resource is zero or greater, the management device 100 determines that the processing order ODC will not cause a resource shortage.

Figure 15 is a diagram that outlines the processing in step S103, which follows step S102.

In step S103, it is assumed that production plan 123C is input to management device 100. Production plan 123C specifies that 50 workpieces WC and 80 workpieces WA should be produced.

The management device 100 references the above-mentioned work information 124 and identifies the raw workpiece W3 and tool T3 as the resources required to produce the workpiece WC specified in the production plan 123C. Next, the management device 100 calculates the amount of resources required to produce 50 workpieces WC. In this example, the amount of resources required is 50 or more times for the remaining number of uses of tool T3, and 50 or more for the number of raw workpieces W3.

Since processing system 200A does not have the resources necessary to process the workpieces WC, management device 100 determines that processing system 200B will be the processing destination for the workpieces WC. Management device 100 then generates a processing order ODD to instruct the processing of 50 workpieces WC and sends this processing order ODD to processing system 200B.

Then, the management device 100 determines whether a resource shortage will occur due to the processing order ODD. In the example of FIG. 15, the management device 100 predicts that the remaining number of times that tool T3 held in processing system 200B can be used will decrease from 100 to 50, and predicts that the remaining quantity of material workpieces W3 held in processing system 200B will decrease from 150 to 100. In this case, because the remaining quantity of each resource is zero or greater, the management device 100 determines that a resource shortage will not occur due to the processing order ODD.

Furthermore, the management device 100 references the above-mentioned work information 124 and identifies the raw workpiece W1 and tool T1 as the resources required to produce the workpiece WA specified in the production plan 123C. Next, the management device 100 calculates the amount of resources required to produce 80 workpieces WA. In this example, the amount of resources required is 80 or more times for the remaining number of uses of tool T1 and 80 or more for the number of raw workpieces W1.

Here, processing system 200A has resources remaining to process 20 workpieces WA, and processing system 200B has resources remaining to process 25 workpieces WA. At this time, processing system 200B has already been assigned a processing order ODD to process workpieces WC, so processing system 200A will become available before processing system 200B. Therefore, management device 100 assigns processing of 55 workpieces WA, including the missing 35 (= 80 - 20 - 25), to processing system 200A. As a result, management device 100 generates a processing order ODE to instruct processing system 200A to process 55 workpieces WA, and a processing order ODF to instruct processing system 200B to process 25 workpieces WA. Management device 100 then sends the processing order ODE to processing system 200A and the processing order ODF to processing system 200B.

The management device 100 then determines whether the processing order ODE will cause a resource shortage. In the example of FIG. 15, the management device 100 predicts that the remaining number of times that tool T1 held in processing system 200A can be used will decrease from 20 to -35, and predicts that the remaining number of raw material workpieces W1 held in processing system 200A will decrease from 120 to 65. In this case, because the remaining number of times that tool T1 can be used is less than zero, the management device 100 determines that the processing order ODE will cause a resource shortage. In this case, the management device 100 outputs a warning indicating a resource shortage, associated with the processing order ODE.

Preferably, the management device 100 predicts when a resource shortage will occur in the processing system 200A. More specifically, the management device 100 references the above-mentioned work information 124 to identify the processing time per workpiece WA. Next, the management device 100 multiplies the identified processing time by the number of workpieces WA that can be processed with the current remaining resources of the processing system 200A (i.e., 20 pieces). The management device 100 then adds the result of this multiplication to the start time of the processing order ODE, and predicts the time indicated by the result of this addition as the time when a resource shortage will occur.

The management device 100 also determines whether a resource shortage will occur due to the processing order ODF. In the example of FIG. 15, the management device 100 predicts that the remaining number of times that tool T1 held in processing system 200B can be used will decrease from 25 to 0, and predicts that the remaining quantity of material workpieces W1 held in processing system 200A will decrease from 100 to 75. In this case, the remaining number of times that tool T1 can be used will become zero, but processing system 200B will not stop until a new processing order using tool T1 is input to processing system 200B. Therefore, the management device 100 determines that a resource shortage will not occur due to the processing order ODF.

As described above, assume that both processing systems 200A and 200B are responsible for processing workpiece WA (first workpiece), and processing system 200B is responsible for processing workpiece WC (second workpiece), and production plan 123C is input to produce workpieces WA and WC. In this case, if the remaining resources of both processing system 200A and processing system 200B become depleted in the process of processing the quantity of workpiece WA indicated in production plan 123C, management device 100 outputs a resource shortage warning for processing system 200A, which is not responsible for processing workpiece WC. In other words, management device 100 does not output a resource shortage warning for processing system 200B.

Note that, although the above description has been given of an example in which no warning is output when the remaining amount of resources is zero, the manner in which a warning is output is not limited to this. When the remaining amount of resources is zero, the management device 100 may output a warning indicating a shortage of resources. Furthermore, when the remaining amount of resources is a predetermined amount or less, the management device 100 may output a warning indicating that the remaining amount of resources is low.

<I. First Modification>
Next, a management system 5 according to a first modified example will be described with reference to Fig. 16. Fig. 16 is a diagram showing an output screen IM2 according to this modified example.

On the output screen IM1 described above (see Figure 4), a warning WR indicating a resource shortage was displayed as a resource bar RB. In contrast, on the output screen IM2 according to this modified example, a warning WRA indicating a resource shortage is displayed as text.

The warning WRA shown in this modified example includes, for example, the identifier of the processing system 200 in which a resource shortage will occur, the identifier of the resource that will be in short supply, the expected date and time when the resource shortage will occur, and the time remaining until the resource shortage will occur. By checking the warning WRA, workers can easily recognize what, where, and when the shortage will occur.

Note that output screens IM1 and IM2 may be configured to be transitionable between each other. In this case, the user can switch the display from output screen IM1 to output screen IM2 by pressing a specific button provided on output screen IM1. Also, the user can switch the display from output screen IM2 to output screen IM1 by pressing a specific button provided on output screen IM2.

<J. Second Modification>
Next, a management system 5 according to a second modified example will be described with reference to Fig. 17. Fig. 17 is a diagram showing an output screen IM3 according to this modified example.

The above-mentioned output screen IM1 (see Figure 4) displayed the processing schedule SCA and resource bar RB. In contrast, the output screen IM3 according to this modified example further displays performance information XA indicating processing performance and work performance.

Actual performance information XA indicates the actual performance related to the workpiece machining process. As an example, the management device 100 periodically acquires the actual performance related to the machining process from the machining system 200 that executes the production plan. The actual performance includes, for example, information on the actual machining time period during which the machining system 200 processed the workpiece, and information on the actual working time period during which workers worked on the pallet. The actual performance also includes stoppage performance information that indicates that machining in the machining system 200 has stopped. The stoppage performance information is issued, for example, when some kind of abnormality occurs in the machining system 200.

The performance information XA is updated in conjunction with the time bar CT, which indicates the current time. The performance information XA contains performance XA1, which indicates the work performance corresponding to time slot TA1 in the processing schedule SCA. As mentioned above, time slot TA1 was the time slot during which the worker was scheduled to attach the first workpiece WA to location α on the pallet PT, and the example in Figure 17 shows that this attachment work was completed as scheduled.

Actual results XA2 included in actual results information XA indicates the processing results corresponding to time period TA2 in the processing schedule SCA. As described above, time period TA2 was the time period during which processing system 200A was scheduled to process the first workpiece WA attached to pallet PT, but the example in Figure 17 shows that processing system 200A is proceeding with processing workpiece WA as scheduled.

By taking into account the performance information XA and checking the warning WR that indicates a resource shortage, workers can more accurately predict when a resource shortage will occur.

The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
