Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional production management system such as Patent Document 1, the work entity (worker or manufacturing equipment) and the method of obtaining performance information are fixed to a certain extent, and these are premised on application to a mass production line where they are fixed to a certain extent. For this reason, the conventional production management system cannot be applied to a production line where the skills required of workers and the types of manufacturing equipment to be used differ for each product, and thus the work entity and the method of obtaining performance information differ for each product, such as a prototype production line or a production line for small-lot production of multiple product types.

Means for Solving the Problems

[0005] The present disclosure can be realized in the following forms. According to one aspect of the present disclosure, a production instruction system that issues production instructions based on a formulated production plan is provided. This system includes a setting reception unit that receives, for a plurality of operations for realizing the production plan, setting of an instruction destination that is a destination of an instruction for the operations included in the plurality of operations, and an operation instruction unit that instructs the operation by transmitting instruction information indicating the instruction for the operation to the set instruction destination. The setting reception unit further receives setting of a transmission destination device of the instruction information, and the operation instruction unit instructs the operation to the set instruction destination by transmitting the instruction information to the set transmission destination device. The setting reception unit further receives setting of an achievement input device for inputting the achievement of the operation, and the production instruction system further includes an achievement acquisition unit that acquires the achievement input from the set achievement input device. The operation instruction unit transmits information indicating the set achievement input device, included in the instruction information, to the transmission destination device. The setting reception unit receives setting of a start achievement input device for inputting the start achievement of the operation and a completion achievement input device for inputting the completion achievement of the operation as the achievement input device. The achievement acquisition unit acquires the start achievement from the set start achievement input device and acquires the completion achievement from the set completion achievement input device. The production instruction system includes an operation identification unit that identifies the operation corresponding to the acquired start achievement or completion achievement, and an achievement notification unit that transmits information indicating the operation identified by the operation identification unit and the achievement to a production plan formulation unit that formulates the production plan, and a determination unit that determines whether or not the achievement acquired by the achievement acquisition unit has been acquired. The determination unit records the achievement as the error log when it determines that the achievement has been acquired, and the achievement notification unit transmits the information indicating the operation and the achievement to the production plan formulation unit when the determination unit determines that the achievement has not been acquired.

[0006] (1) According to one embodiment of the present disclosure, a production instruction system is provided. The production instruction system is a production instruction system that gives production instructions based on a formulated production plan, and for a plurality of operations to realize the production plan, a setting reception unit that receives setting of an instruction destination which is a destination of an instruction for an operation included in the plurality of operations, and an operation instruction unit that instructs the operation by transmitting instruction information indicating the instruction for the operation to the set instruction destination. According to the production instruction system of this embodiment, for a plurality of operations to realize the production plan, there are provided a setting reception unit that receives setting of an instruction destination which is a destination of an instruction for an operation included in the plurality of operations, and an operation instruction unit that instructs the operation by transmitting instruction information indicating the instruction for the operation to the set instruction destination. Therefore, even in a production line where the skills required of workers and the manufacturing equipment to be used differ for each product, such that the working entity differs for each product, like a prototype production line or a production line for small-lot production of multiple product types, it is possible to specify a destination and give an operation instruction to an appropriate destination, as compared to a configuration where the instruction destination is fixed. (2) In the production instruction system of the above embodiment, the setting reception unit may further receive setting of a transmission destination device of the instruction information, and the operation instruction unit may instruct the operation to the set instruction destination by transmitting the instruction information to the set transmission destination device. According to the production instruction system of this embodiment, since the setting reception unit further receives setting of a transmission destination device of the instruction information, for example, when the instruction destination is a worker and such worker may use a plurality of devices, it is possible to transmit the instruction information to an appropriate device. (3) In the production instruction system of the above-described form, the setting reception unit further receives the setting of a result input device for inputting the results of the work, and the production instruction system further includes a result acquisition unit that acquires the results input from the set result input device. The work instruction unit may transmit information indicating the set result input device to the destination device included in the instruction information. According to the production instruction system of this form, since the setting reception unit further receives the setting of a result input device for inputting the results of the work, and the work instruction unit transmits information indicating the set result input device to the destination device included in the instruction information, it is possible to instruct the input of results from an appropriate device. Further, since the production instruction system further includes a result acquisition unit that acquires the results input from the set result input device, even in a production line where the skills required of the operator and the types of manufacturing facilities to be used differ for each product, such as a prototype production line or a production line for small-lot production of multiple product types, and thus the method of acquiring result information differs for each product, it is possible to acquire the results from an appropriate result input device. (4) In the production instruction system of the above-described form, the setting reception unit receives the setting of a start result input device for inputting the start result of the work and a completion result input device for inputting the completion result of the work as the result input device, and the result acquisition unit may acquire the start result from the set start result input device and acquire the completion result from the set completion result input device. According to the production instruction system of this form, since the setting reception unit receives the setting of the start result input device and the completion result input device, and the result acquisition unit acquires the start result from the set start result input device and acquires the completion result from the set completion result input device, it is possible to acquire the start result and the completion result from appropriate devices. In particular, when the set start result input device and the completion result input device are different devices, it is possible to acquire the start result and the completion result from appropriate devices respectively. (5) In the production instruction system of the above form, for the above work, a work master table in which a plurality of combination patterns of the instruction destination, the transmission destination device, the start result input device, and the completion result input device are associated in advance with pattern identification information is further provided. In the production plan, the pattern identification information is recorded together with the content of the work. The setting reception unit may receive the setting of the instruction destination, the transmission destination device, the start result input device, and the completion result input device for the work when the production plan in which the pattern identification information is recorded is input. According to the production instruction system of this form, for the work, a work master table in which a plurality of combination patterns of the instruction destination, the transmission destination device, the start result input device, and the completion result input device are associated in advance with pattern identification information is further provided. In the production plan, the pattern identification information is recorded together with the content of the work. Therefore, one item of pattern identification information can be input rather than four items of the instruction destination, the transmission destination device, the start result input device, and the completion result input device being input respectively. For this reason, by such a simple method, the setting reception unit can receive the setting of the instruction destination, the transmission destination device, the start result input device, and the completion result input device. (6) In the production instruction system of the above form, the work instruction unit has an instruction information transmission unit that transmits the instruction information to the transmission destination device. The transmission destination device has a display unit. The instruction information transmission unit transmits, as the instruction information, information indicating instruction content that can be understood by an operator when displayed on the display unit to the transmission destination device, and the display unit may display the information indicating the instruction content. According to the production instruction system of this form, when the information indicating the instruction content is displayed on the display unit of the transmission destination device, the operator can understand the information indicating the instruction content. (7) In the production instruction system of the above-described form, the start achievement includes information indicating the start achievement input device, information indicating the number of objects to be worked on, and identification information. The completion achievement may include information indicating the completion achievement input device, information indicating the number of objects to be worked on, and identification information. According to the production instruction system of this form, since the start achievement or the completion achievement includes information indicating the start achievement input device or the completion achievement input device, it is possible to identify on which device the start achievement or the completion achievement was transmitted. Also, since the start achievement or the completion achievement includes information indicating the number of objects to be worked on, it is possible to identify the number of objects to be worked on. (8) In the production instruction system of the above-described form, it may further include a work identification unit that identifies the work corresponding to the obtained start achievement or completion achievement, and an achievement notification unit that transmits information indicating the work identified by the work identification unit and the achievement to the production plan formulation unit that formulates the production plan. According to the production instruction system of this form, the achievement notification unit transmits information indicating the work identified by the work identification unit, in other words, information indicating the planned work, and the achievement to the production plan formulation unit, so that it becomes possible to use the work achievement in the production plan formulation unit. (9) According to another form of the present disclosure, a production instruction system is provided. This production instruction system is a production instruction system that gives production instructions based on a formulated production plan. In the production plan, for a plurality of operations to realize the production plan, a result input device for inputting the results of the plurality of operations is preset. The result acquisition unit acquires the input result and device identification information that can identify the result input device from the result input device. The work identification unit is provided, which identifies the work corresponding to the obtained result using the obtained result and the device identification information. According to the production instruction system of this form, a performance acquisition unit that acquires the input performance and device identification information capable of identifying the performance input device from the performance input device, and a work identification unit that identifies the work corresponding to the performance using the acquired performance and device identification information are provided. Therefore, even in a production line where the types of manufacturing equipment to be used differ for each product, such as a prototype production line or a production line for small-lot production of multiple product types, and thus the method for acquiring performance information differs for each product, performance information can be appropriately collected. (10) In the production instruction system of the above form, the performance acquisition unit may acquire the completion performance as the performance from a completion performance input device that inputs the completion performance of the work. According to the production instruction system of this form, the completion performance of the work can be acquired as the performance. Therefore, based on the acquired completion performance of the work, the identification accuracy of the work corresponding to the performance is improved. (11) In the production instruction system of the above form, the performance acquisition unit may further acquire the start performance as the performance from a start performance input device that inputs the start performance of the work. According to the production instruction system of this form, the start performance of the work can be further acquired as the performance. Therefore, based on the further acquired start performance of the work, the identification accuracy of the work corresponding to the performance is further improved. (12) In the production instruction system of the form (9) above, the performance input device may be any one of a PLC, a signal tower, an information code reader, and a tablet. According to the production instruction system of this form, it is possible to handle different types of performance input devices.

Mode for Carrying Out the Invention

[0008] A. First Embodiment: A1. Schematic Configuration of Production Instruction System: FIG. 1 is a schematic block diagram showing the configuration of a production instruction system 100 according to an embodiment of the present disclosure. The production instruction system 100 is a system that gives production instructions based on a formulated production plan. The production instruction system 100 is used together with a production line (not shown). The production instruction system 100 is applicable to a mass production type production line, but is not limited to the mass production type and is also applicable to a multi-variety small-lot type production line. As shown in FIG. 1, the production instruction system 100 includes an operation instruction / result processing device 10, devices 30A, 30B, 30C, 30D, and a production plan device 40. The operation instruction / result processing device 10 and the production plan device 40 are communicatively connected to each other by a local area network 1 (hereinafter referred to as "LAN1"). In the present embodiment, LAN1 is configured by a wired LAN (Local Area Network) defined by IEEE802.3 or the like. Note that, instead of the wired LAN, any other type of network such as a wireless LAN (Local Area Network) defined in IEEE802.11 may be used.

[0009] The operation instruction and performance processing device 10 and the devices 30A to 30D are communicatively connected to each other by a local area network 2 (hereinafter referred to as "LAN2"). In the present embodiment, LAN2 is configured by a wireless LAN (Local Area Network) defined in IEEE802.11. Note that, instead of the wireless LAN, any other type of network such as a wired LAN (Local Area Network) defined by IEEE802.3 or the like may be used. Note that LAN1 and LAN2 may belong to the same segment or may be independent segments.

[0010] Figure 2 is a block diagram showing the configuration of the operation instruction and performance processing device 10. The operation instruction and performance processing device 10 is a device that issues operation instructions and processes the performance of such operations. The operation instruction means an instruction for each operation included in a plurality of operations for realizing a production plan. In the present embodiment, the "performance" has a start performance and a completion performance, which will be specifically described later. As shown in Figure 2, the operation instruction and performance processing device 10 is configured by a computer including a CPU (Central Processing Unit) 11, a storage unit 22, and an input / output interface 24. The storage unit 22 has a ROM (Read Only Memory) and a RAM (Random Access Memory). The input / output interface 24 is used to input and output command values and output values between the operation instruction and performance processing device 10 and the outside.

[0011] The CPU 11 functions as an operation instruction unit 12, a performance acquisition unit 14, an operation identification unit 16, a determination unit 18, and a performance notification unit 20 by executing a control program stored in advance in the storage unit 22.

[0012] The operation instruction unit 12 instructs operations for a plurality of operations to achieve the production plan, according to the instruction destination which is the destination of the operation instruction included in such a plurality of operations and the destination device of the instruction information indicating the operation instruction. Note that the instruction destination and the destination device are set by a setting reception unit 44 described later. In the present embodiment, the destination device is any one of the devices 30A to 30D shown in FIG. 1. The devices 30A to 30D are devices that receive operation instructions and input results. For example, the devices 30A to 30D are each constituted by, for example, any one of a tablet, a QR reader, a PLC (Programmable Logic Controller), and a signal tower. The operation instruction unit 12 includes an instruction information transmission unit 12A. The instruction information transmission unit 12A transmits instruction information to any one of the destination devices 30A to 30D. Note that the devices 30A to 30D are not limited to any one of a tablet, a QR reader, a PLC, and a signal tower, and may be constituted by any other type of device as long as the effects of the present embodiment are achieved.

[0013] The result acquisition unit 14 acquires the start result from the set start result device and acquires the completion result from the set completion result device. The operation identification unit 16 identifies the operation corresponding to the acquired start result and completion result. The determination unit 18 determines whether or not there is a match by collating the result device of the operation master table described later with the device of the input result.

[0014] The result notification unit 20 transmits information indicating the operation identified by the operation identification unit 16 and the result to a production plan formulation unit 42 described later. The description of the processing performed by each of the above functional units 12 to 20 will be given later.

[0015] FIG. 3 is a block diagram showing the configuration of the production planning apparatus 40. The production planning apparatus 40 is an apparatus that schedules a production plan.

[0016] As shown in FIG. 3, the production planning device 40 is configured by a computer including a CPU 41, a storage unit 50, and an input / output interface 52. The storage unit 50 has a ROM (Read Only Memory) and a RAM (Random Access Memory). In the storage unit 50, pattern identification information is stored together with the content of the work as a formulated production plan. The input / output interface 52 is used to input and output command values and output values between the production planning device 40 and the outside.

[0017] By executing a control program stored in advance in the storage unit 50, the CPU 41 functions as a production plan formulation unit 42 and a setting reception unit 44.

[0018] The production plan formulation unit 42 schedules the production plan made by humans. Specifically, the production plan formulation unit 42 sets the time schedule for each work of the production plan. For example, the production plan formulation unit 42 sets the timing when the finished product is completed and the time schedule for each work according to such timing so as to meet the set delivery date.

[0019] FIG. 4 is a diagram showing an example of production plan information. The administrator creates the production plan information shown in FIG. 4 using the production planning device 40 and stores such production plan information in the storage unit 50 in advance. The "Process No." shown in FIG. 4 is a number indicating the order assigned to each work. The "Equipment Name" is the name of the equipment for which the work is performed. The "Work Name" is the name of the work. The "Classification" is a classification of whether it is "manual work" performed by humans or "equipment production" in which the equipment performs the work. The "Pattern" is information for uniquely identifying the work instruction method and the like, and such pattern will be described later.

[0020] An illustrative description will be given of the uppermost row in FIG. 4. In this uppermost row, for the operation of Process No. "010", in the equipment with the equipment name "AA1234", the operation of "tool changeover" is performed manually, and it is set that the pattern of the operation instruction method and the like is "1". The same setting is made for each operation in each row. The thick arrow shown in FIG. 4 indicates the process order, showing that the operation progresses from the upper row to the lower row. In the present embodiment, the finished product is completed after the "inspection" in the lowermost row of FIG. 4.

[0021] FIG. 5 is a diagram showing a setting example of an operation master table. The operation master table means a table in which the operation instruction method and the actual result input method for each operation are associated. The operation master table is generated by the administrator using the production planning device 40 and stored in the storage unit 50 in advance. For example, the setting example of the operation master table shown in FIG. 5 is stored in the storage unit 50 in advance. In the two operations shown in FIG. 5, four combination patterns of the operation instruction method and the actual result input method are set respectively.

[0022] The "Operation Name" shown in Fig. 5 is the same as the "Operation Name" in Fig. 4. Also, the "Standard Destination" indicates whether it is "Manual Work" performed by a person or "Equipment Production" performed by equipment, which is the same as the "Classification" shown in Fig. 4. The "Pattern" is also the same as in Fig. 4. The "Destination" in the operation instruction method indicates the recipient of the operation instruction. The "Instruction Device" means the destination device for transmitting information indicating the operation instruction (hereinafter referred to as "instruction information"). When the operation is performed by a person, the destination is the operator, and the instruction device corresponds to a device that gives instructions to such an operator (for example, a device that displays instructions). In this case, for example, when information indicating the instruction content is displayed on the tablet that the operator has received the instruction information, the operator will perform the instructed operation by looking at such information. When the operation is performed by equipment, the "destination" is the equipment or the operator, and the "instruction device" corresponds to the same equipment (for example, a PLC), or a device that gives instructions to the operator (for example, a device that displays instructions). The "Start Performance Device" in the performance input method means the device for inputting that the operation has started, and the "Completion Performance Device" means the device for inputting that the operation has been completed.

[0023] The part surrounded by the thick line in Fig. 5 shows the operation instruction method and the performance input method in the uppermost row of Fig. 4. For example, for the "Manual Work" of "Fixture Changeover", in the case of Pattern 1, the destination is the "Operator", the instruction device is the "Tablet", the start performance device is the "Tablet", and the completion performance device is the "Tablet". In this case, the operation instruction for the "Manual Work" of "Fixture Changeover" is sent to the "Tablet" of the operator who performs such work. Note that a user interface for inputting start and completion performance is displayed on the tablet. The operator touches the "Start" button on the display part of such a tablet at the start of the operation and then starts the operation, and touches the "Completion" button on the display part of such a tablet after the completion of the operation.

[0024] As shown in the second - stage pattern 2 of FIG. 5, when the start achievement device is a "QR reader", the operator to whom the work instruction for jig change - over is sent to the display unit of the tablet uses the QR reader to read the QR code (registered trademark) attached to the jig. Reading such a QR code corresponds to the input of the start achievement. Since the "QR code" attached to the jig is read and the work is started, the mistake in the jig to be exchanged is suppressed. Also, as shown in the third - stage pattern 3 of FIG. 6, when both the start achievement device and the completion achievement device are "QR readers", the QR code attached to the jig is read for start and completion, so the mistake in the jig is further suppressed. As shown in the fourth - stage pattern 4 of FIG. 5, the case where the "completion achievement device" is not set corresponds to, for example, the case of exchanging a general - purpose jig that can be attached with one touch. In this case, the types of general - purpose jigs are few and the jig exchange often ends in a short time. In such a case, since there are almost no mistakes, the completion achievement is set as not required to be acquired.

[0025] As shown in FIG. 4, after the "fixture changeover" operation, the "bottom surface processing" operation is performed by the equipment. As shown in FIG. 5, in the case of Pattern 1 in the "bottom surface processing" operation, the instruction destination, the instruction device, the start achievement device, and the completion achievement device are all "PLCs". In the present embodiment, the "PLC" is a computer inside the equipment. In the case of this Pattern 1, since the "PLC" inside the equipment is directly instructed by a program and the start and completion are automatically performed, the "bottom surface processing" operation is performed without manual intervention. Also, in the case of Pattern 2 in the "bottom surface processing" operation, it differs from Pattern 1 only in the work instruction method. Specifically, Pattern 2 is a pattern in which a work instruction is sent to the operator's tablet, and such an operator presses the equipment start button. When the equipment is started, a series of operations are performed by a ladder program or an NC program, etc., and the start achievement is transmitted by the PLC at the start of the operation, and the completion achievement is transmitted by the PLC at the completion. Pattern 3 is a pattern where both the start achievement device and the completion achievement device are signal towers. This is a case where a signal tower is used more simply without using the equipment's PLC for transmission. In the case of this Pattern 3, a signal tower is installed adjacent to the equipment, and such a signal tower lights green when the equipment is not operating and lights yellow when the equipment is operating. When an operator presses the equipment start button to start the equipment, the lighting color of the signal tower changes from green to yellow. When a series of operations of the equipment are completed, such a color change is reversed. Triggered by these color changes, the signal tower transmits the start achievement or the completion achievement, and the achievement acquisition unit 14 acquires such an achievement. Also, in the case of Pattern 4, both the start achievement device and the completion achievement device are "tablets". When transmission from a signal tower like Pattern 3 is not possible, the operator's tablet becomes the achievement input device. Such cases include, for example, when there is a new piece of equipment that is not connected to a network and exists alone, and when direct instruction to the equipment is not possible. In the case of Pattern 4, although the "bottom surface processing" operation is performed by the equipment, the start achievement input and the completion achievement input are performed by the operator using a tablet.

[0026] The setting reception unit 44 shown in FIG. 3 receives settings for the instruction destination, the instruction device, the start achievement device, and the completion achievement device. In the present embodiment, these settings are received by receiving an input of a production plan. Details of such setting reception will be described later.

[0027] A2. Production instruction and achievement processing: FIG. 6 is a flowchart showing the procedure of production instruction and achievement processing. In the present embodiment, when scheduling is performed in the production plan creation unit 42 of the production planning apparatus 40 shown in FIG. 3, the production instruction and achievement processing shown in FIG. 6 is executed. Specifically, when the production plan creation unit 42 performs time scheduling using the production plan and the work master table stored in advance in the storage unit 50, the production instruction and achievement processing is executed. The production instruction and achievement processing is processing for performing production instruction and achievement acquisition based on such time scheduling.

[0028] As shown in FIG. 6, the setting reception unit 44 receives settings for the instruction destination, the instruction device, the start achievement device, and the completion achievement device (step S10). As described above, in this embodiment, pattern identification information is recorded in the production plan. And this pattern identification information indicates a combination pattern of the instruction destination, the instruction device, the start achievement device, and the completion achievement device in the work master table. Therefore, in this embodiment, inputting a production plan in which pattern identification information is recorded is equivalent to receiving settings for the instruction destination, the instruction device, the start achievement device, and the completion achievement device. For example, in the "fixture changeover" work, which is the topmost work in the production plan shown in FIG. 4, pattern identification information "1" is set. Referring to the work master table shown in FIG. 5, for such pattern identification information "1", "worker" is set as the instruction destination, "tablet" is set as the instruction device, "tablet" is set as the start achievement device, and "tablet" is set as the completion achievement device. Therefore, by inputting the production plan, these settings are received. The setting reception unit 44 transmits the work instruction information and the identification number of the production plan to the work instruction / achievement processing device 10 via the input / output interface 52.

[0029] The work instruction unit 12 acquires the work instruction information and the identification number of the production plan via the input / output interface 24 and stores them in the storage unit 22. The work instruction information is instruction information including the work name, the standard instruction destination, the instruction destination, the instruction device, the start achievement device, and the completion achievement device. The work instruction information is specifically based on the information set by the setting reception unit 44. Note that the identification number of the production plan is preset by the administrator and stored in the storage unit 50. In the case of process No. "010", the work instruction unit 12 refers to the instruction information of the pattern identification information "1" of the "fixture changeover" work. Specifically, the work instruction unit 12 refers to the instruction destination "to the worker", the instruction device "to the tablet", the start achievement device "from the tablet", and the completion achievement device "from the tablet" shown in the topmost row of FIG. 5.

[0030] As shown in FIG. 6, the instruction information transmission unit 12A issues a work instruction by transmitting the instruction information together with the identification number of the production plan to the instruction device (step S12). For example, in the transmission of the "fixture change work" of process No. "010", the instruction information transmission unit 12A transmits, as the instruction information, information indicating the instruction content understandable by the operator when displayed on the display unit of the tablet, to the operator's tablet. Specifically, the instruction information transmission unit 12A may send the portion enclosed by the thick line at the uppermost stage of FIG. 5 as it is to the operator's tablet, or the work instruction method and the actual result input method may be listed item by item, or it may be expressed in words such as "Please perform the fixture change work and touch 'Start' or 'Completion' on the display unit of the tablet to notify the actual result.", and not limited to these, any method may be used as long as the operator can understand the instruction content on the display unit of the tablet.

[0031] When the operator starts the work, the operator touches "Start". Also, when the operator completes the work, the operator touches "Completion". Such a touch becomes the input of the actual result. Thus, when the operator touches "Start" or "Completion" on the display unit of the tablet, the actual result acquisition unit 14 acquires "start actual result" or "completion actual result" from the tablet. Specifically, the actual result acquisition unit 14 acquires "start actual result" or "completion actual result" via the input / output interface 24 and stores it in the actual result reception area of the storage unit 22 together with the identification number of the production plan (step S14). At this time, "start actual result" or "completion actual result" is stored in the reception area for the tablet of the storage unit 22 together with the identification number of the production plan.

[0032] The work identification unit 16 identifies the work corresponding to the "start actual result" or "completion actual result" stored in the storage unit 22 in step S14 (step S16). For example, the work identification unit 16 uses the identification number of the production plan to collate the instruction information of the "fixture change" work pre-stored in the storage unit 22 with the "start actual result" or "completion actual result" in the reception area for the tablet of the storage unit 22, and identifies the "fixture change" work for which the actual result acquisition is scheduled to correspond.

[0033] The determination unit 18 collates the "start achievement device" or "completion achievement device" in the work master table of FIG. 5 with the "start achievement device" or "completion achievement device" acquired and stored in the storage unit 22 (step S18). The determination unit 18 determines whether or not the two match as a result of the collation (step S20). In the present embodiment, when the achievement devices do not match (step S20: No), the determination unit 18 records the achievement information acquired and stored in the storage unit 22 in the storage unit 22 as an error log (step S26).

[0034] When the achievement devices match (step S20: Yes), the determination unit 18 determines whether or not the achievement has been acquired (step S22). Specifically, the determination unit 18 refers to the achievement collection area of the storage unit 22 to determine whether or not the achievement of the target work has been acquired. When it is determined that the achievement has been acquired (step S22: Yes), the determination unit 22 records the achievement information acquired and stored in the storage unit 22 in the storage unit 22 as an error log (step S26).

[0035] When it is determined that the achievement has not been acquired (step S22: No), the achievement notification unit 20 performs achievement feedback (step S24). Specifically, the achievement notification unit 20 transmits information indicating the "fixture changeover" work specified by the work specifying unit 16 and the start achievement or completion achievement to the production plan formulation unit 42. Such achievement includes not only information indicating the tablet that is the achievement transmission source device, but also information indicating the number of objects targeted for the "fixture changeover" work, identification information, and time information such as the start time or completion time. Thereby, in the production plan formulation unit 42, the number of objects targeted for the work and the achievement time can be utilized. For example, these pieces of information may be used to improve the production plan. After step S24, the process returns to step S10.

[0036] The "instruction device", "start achievement device", and "completion achievement device" in the first embodiment respectively correspond to the "transmission destination device", "start achievement input device", and "completion achievement input device" in the present disclosure.

[0037] According to the production instruction system 100 of the first embodiment described above, for a plurality of operations to realize a production plan, there are provided a setting reception unit 44 that receives setting of an instruction destination which is a destination of an instruction for an operation included in the plurality of operations, and an operation instruction unit 12 that instructs an operation by transmitting instruction information indicating the instruction for the operation to the set instruction destination. Therefore, even in a production line where the skills required of workers and the manufacturing facilities to be used differ for each product, such that the working entity differs for each product, like a prototype production line or a production line for multi-variety and small-batch production, compared to a configuration where the instruction destination is fixed, it is possible to specify a destination and give an operation instruction to an appropriate destination.

[0038] Also, since the setting reception unit 44 further receives setting of an instruction device for the instruction information, for example, when the instruction destination is a worker and such a worker may use a plurality of devices, it is possible to transmit the instruction information to an appropriate device.

[0039] Also, the setting reception unit 44 further receives setting of an achievement input device for inputting the achievement of the operation, and the operation instruction unit 12 includes information indicating the set achievement input device in the instruction information and transmits it to the instruction device. Therefore, it is possible to instruct achievement input from an appropriate device. Further, since the production instruction system further includes an achievement acquisition unit 14 that acquires the achievement input from the set achievement input device, even in a production line where the skills required of workers and the types of manufacturing facilities to be used differ for each product, such that the method of acquiring achievement information differs for each product, like a prototype production line or a production line for multi-variety and small-batch production, it is possible to acquire the achievement from an appropriate achievement input device.

[0040] In addition, the setting reception unit 44 receives the settings of the start achievement device and the completion achievement device, and the achievement acquisition unit 14 acquires the start achievement from the set start achievement device and the completion achievement from the set completion achievement device. Therefore, the start achievement and the completion achievement can be acquired from appropriate devices. In particular, when the set start achievement device and the completion achievement device are different devices, the start achievement and the completion achievement can be acquired from appropriate devices respectively.

[0041] Furthermore, for the work, there is further provided a work master table in which a plurality of combination patterns of the instruction destination, the instruction device, the start achievement device, and the completion achievement device are associated in advance with pattern identification information respectively. Since the pattern identification information is recorded in the production plan together with the content of the work, rather than the four items of the instruction destination, the instruction device, the start achievement device, and the completion achievement device being input respectively, one item of pattern identification information can be input. For this reason, by such a simple method, the setting reception unit 44 can receive the settings of the instruction destination, the instruction device, the start achievement device, and the completion achievement device.

[0042] In addition, the work instruction unit 12 has an instruction information transmission unit 12A that transmits instruction information to the instruction device. The instruction device has a display unit. The instruction information transmission unit 12A transmits, as the instruction information, information indicating the instruction content that can be understood by the operator when displayed on the display unit to the instruction device. The display unit displays the information indicating the instruction content. Therefore, when the information indicating the instruction content is displayed on the display unit of the instruction device, the operator can understand the information indicating the instruction content.

[0043] In addition, since the start achievement includes information indicating the start achievement device and information indicating the number of objects or identification information, it is possible to specify in which device the start achievement was transmitted. Also, it is possible to specify the object or the number of objects that were the target of the work. In addition, since the completion achievement includes information indicating the completion achievement device and information indicating the number of objects or identification information, it is possible to specify in which device the completion achievement was transmitted, and also to specify the object or the number of objects that were the target of the work.

[0044] Also, the performance notification unit 20 transmits information indicating the work specified by the work specifying unit 16, in other words, information indicating the planned work, and the performance to the production plan formulation unit 42, so that the production plan formulation unit 42 can utilize the work performance.

[0045] B. Second Embodiment: The schematic configuration of the production instruction system 100 of the second embodiment is the same as that of the production instruction system 100 of the first embodiment. Thus, the same reference numerals are assigned to the same components, and detailed descriptions thereof are omitted. FIG. 7 is a flowchart showing the procedure of performance processing in the second embodiment. The procedure of performance processing in the second embodiment differs from the procedure of production instruction and performance processing in the first embodiment in that the reception of settings and the processing of work instructions are not performed. In the production instruction system 100 of the second embodiment, the input of performance from the performance input device may be autonomously performed without being triggered by the processing of work instructions in the first embodiment. Other procedures in the procedure of performance processing in the second embodiment are the same as the procedures of production instruction and performance processing in the production instruction system 100 of the first embodiment. Thus, the same reference numerals are assigned to the same procedures, and detailed descriptions thereof are omitted. Note that in the production instruction system 100 of the second embodiment, instructions based on the production plan are separately sent to the workers.

[0046] In the second embodiment, when performance is input from the performance input device, the performance process shown in FIG. 7 is executed. The performance acquisition unit 14 acquires, via the input / output interface 24, the "start performance" or "completion performance" input from the performance input device and device identification information capable of identifying the performance input device (step S14). The device identification information corresponds to, for example, the number of the facility, the serial number of the target product, etc. Here, the number of the facility means, for example, the manufacturing number of the facility, the model number of the facility, etc. The target product means the product to be processed. The work identification unit 16 identifies the corresponding work using the acquired "start performance" or "completion performance" and the device identification information. Note that in the production plan, a performance input device for inputting the performance of the work for realizing the production plan is preset for each work.

[0047] In the second embodiment, the performance acquisition unit 14 acquires, from a facility (for example, a PLC), the completion performance of the work, the number of the facility, the serial number of the target product, etc. Such completion performance of the work, the number of the facility, the serial number of the target product, etc. are used for collation with the performance input device and the device identification information preset in the production plan. As described above, the processing after step S14 is the same as that in the first embodiment.

[0048] According to the production instruction system 100 of the second embodiment described above, there are provided a performance acquisition unit 14 that acquires the input performance and device identification information capable of identifying the performance input device from the performance input device, and a work identification unit 16 that identifies the work corresponding to the performance using the acquired performance and device identification information. Therefore, even in a production line where the types of manufacturing facilities to be used differ for each product, such as a prototype production line or a production line for multi-variety and small-batch production, and thus the method for acquiring performance information differs for each product, performance information can be appropriately collected.

[0049] In addition, the performance acquisition unit 14 can acquire the completion performance of the work as a performance. Therefore, based on the acquired completion performance of the work, the identification accuracy of the work corresponding to the performance is improved. Further, the performance acquisition unit 14 can acquire the start performance of the work as a performance. Therefore, based on the further acquired start performance of the work, the identification accuracy of the work corresponding to the performance is further improved.

[0050] C. Other embodiments: (C1) In the production instruction system 100 of the above embodiment, the work master table shown in FIG. 5 may be omitted. In such a configuration, at the time of production plan formulation, the instruction destination, the instruction device, the start performance device, and the completion performance device may be set. Also in this configuration, by inputting a production plan in which the instruction destination, the instruction device, the start performance device, and the completion performance device are explicitly set, the setting of the instruction destination, the instruction device, the start performance device, and the completion performance device can be accepted.

[0051] (C2) In the above embodiment, the pattern identification information was set in advance as part of the production plan, but the present disclosure is not limited to this. At the time of formulating the production plan, the pattern identification information and each parameter defining the work instruction method and the performance input method such as the "instruction destination" are not included in the production plan, and these parameters may be set later. Specifically, in the production plan device 40 or the work instruction / performance processing device 10, a user interface for accepting the input of each parameter such as the instruction device, the start performance device, and the completion performance device may be provided, and each parameter input from such a user interface may be stored in the storage unit 22 in association with the production plan.

[0052] (C3) In the production instruction system 100 of the above embodiment, the work instruction unit 12 instructs the work according to the set instruction destination, the instruction device, and the performance input device, but such a performance input device may not be provided. Specifically, the work instruction unit 12 may instruct the work only according to the set instruction destination. Also, the work instruction unit 12 may instruct the work according to the set instruction destination and the instruction device.

[0053] (C4) In the production instruction system 100 of the second embodiment, the performance input device was a PLC, but it is not limited to a PLC, and it may be any one of a signal tower, an information code reader, or a tablet. According to the production instruction system of this form, it is possible to support different types of performance input devices. When the performance input device is a signal tower, as described above in the first embodiment, taking the change in the color of the signal tower as an opportunity, the signal tower inputs the start performance or the completion performance and the equipment number, etc. of the equipment where the signal tower is installed, and the performance acquisition unit 14 acquires such performance and the equipment number, etc. of the equipment. Also, when the performance input device is an information code reader, the information code reader simultaneously reads the start performance or the completion performance and the number, etc. of the equipment, and the performance acquisition unit 14 acquires such performance and the number, etc. of the equipment.

[0054] (C5) In the production instruction system of the above embodiment, the QR reader was one of the performance input devices, but it is not limited to a QR reader, and it may be an information code reader that reads any two-dimensional code. Also, it is not limited to a two-dimensional code, and it may be an information code reader that reads any one-dimensional code.

[0055] The present disclosure is not limited to the above-described embodiments, and can be realized in various configurations without departing from the gist thereof. For example, the technical features of the embodiments corresponding to the technical features in each form described in the summary of the invention can be appropriately replaced or combined in order to solve part or all of the above-described problems, or to achieve part or all of the above-described effects. Also, if the technical feature is not described as essential in this specification, it can be appropriately deleted.
