Calculated by T1 + YT11 (step S004). Specifically, the work detection unit 126 refers to the production plan 201 and the work master 115 for the post-internal setup work Y11 specified in step S003, and sets the attributes of the product of the work step Y1 as the pretreatment attribute 115w and the work. The attributes of the product in step Y2 are associated with the attribute 115x to specify the setup conditions that match the combination, and the standard working time 115y related to the combination is specified as the working time YT11 for the post-internal setup. Then, the work detection unit 126 calculates the time T2 at which the equipment X becomes available by T1 + YT11.

Next, the work detection unit 126 performs the work Y21 of the front inner setup of the work step Y2 when continuing from the work step Y1 in the equipment X to the next work step Y2, and the work Y22 of the front outer setup and the front outer setup. The work time YT22 of the work Y22 is specified (step S005). Specifically, the work detection unit 126 refers to the work master 115 and specifies the front inner setup work Y21 and the front outer setup work Y22 of the setup work 115j of the equipment X. Then, the work detection unit 126 refers to the production plan 201 and the work master 115 for the front outer setup work Y22, and sets the attributes of the product of the work process Y1 as the pretreatment attribute 115w and the attributes of the product of the work process Y2. The setup conditions matching the combination are specified in association with the attribute 115x, and the standard working time 115y related to the combination is specified as the working time YT22 of the front outer setup. When the inventory of parts and raw materials is insufficient in the setup work, the work detection unit 126 calculates the time required for transportation from the storage location to the equipment according to the transportation speed and the transportation distance, and sets up the front and outer parts. The working time may be added to YT22.

Next, the work detection unit 126 calculates the scheduled start time T3 of the front outer setup work of the next work step Y2 in the equipment X by T2-YT22 (step S006). Specifically, the work detection unit 126 calculates the scheduled start time T3 of the front outer setup work of the next work step Y2 of the equipment X by T2-YT22.

Next, the work detection unit 126 adds the rear inner setup work Y11, the rear outer setup work Y12, the front inner setup work Y21, and the front outer setup work Y22 in the equipment X to the work list (step S007).

The above is the flow of the setup work extraction process. According to the setup work extraction process, the time required for the setup work can be determined in detail according to the combination of the attributes of the previous and next processes, so that it is possible to provide a work instruction device having a shorter waiting time. ..

FIG. 13 is a flowchart showing an example of the work instruction creation process. First, the work instruction creation unit 127 specifies a free time zone for each work subject (step S101). Specifically, the work instruction creation unit 127 refers to the production plan 201 and the main body state table 112, and specifies a time zone in which the work is in charge and a time zone in which the work is not in charge for each work main body.

Then, the work instruction creation unit 127 performs the processes of step S102 and step S103, which will be described later, for each of the setup work to which the work subject in the work list has not been assigned.

The work instruction creation unit 127 sorts and assigns the work subject in the free time zone according to the priority of the required ability of the setup work (step S102). Specifically, the work instruction creation unit 127 extracts work entities whose work entity is not in charge of the work during the unallocated setup work time zone, and gives priority to the work entity that satisfies the required ability of the setup work. Sort according to the degree and assign as the work subject in order by the number of requests. For example, the work that can be in charge and the priority 116b is paint replacement priority is "1", cutting priority is "2", painting machine operation priority is "3", and transportation priority is "4". Person A800 and worker C820 whose assembly work priority is "1", painter operation priority is "2", and paint replacement priority is "3" are the work subjects in the free time zone. In the process of allocating the setup work for paint replacement, the work instruction creating unit 127 assigns the worker A800, which has a higher priority of paint replacement, “1” to the person in charge of the setup work.

Not limited to this, the work instruction creation unit 127 may refer to the instruction master 116 and use the second sort key 116f to the nth sort key 116g to prioritize the work subject and assign it to the person in charge of the work. good. For example, if the "priority" of the first sort key 116e does not make a difference in the order of priority, the work subject's current position is closer to the work equipment by using the second sort key 116f "distance from the equipment". You may give priority to the allocation.

The work instruction creation unit 127 creates a work instruction using the work instruction template 116h of the instruction master 116 (work subject, distribution method specification) (step S103). Specifically, the work instruction creation unit 127 reads the work instruction template 116h of the instruction master 116 related to the setup work, dynamically embeds the parameters related to the equipment, the time, and the work content in the text, and the work subject and the distribution method. And create work instructions. In addition, depending on the availability of the equipment, the work instruction creation unit 127 sets the transport destination of the parts from the equipment that produces the parts used in the unprocessed process to the equipment of the next process, or makes a predetermined provisional provision. Specify whether to use it as a storage place, and give work instructions to the worker including the destination.

The above is the flow of the work order creation process. According to the setup work extraction process, the work subject required for the setup work can be appropriately determined by using the work priority, so that the work can be instructed to the work subject more efficiently.

FIG. 14 is a flowchart showing an example of work instruction distribution processing (periodic execution). The work instruction distribution process (periodic execution) is executed periodically, for example, every 30 minutes. First, the work instruction distribution unit 128 performs the processes of steps S201 to S203, which will be described later, for each of the undelivered work instructions.

The work instruction distribution unit 128 determines whether or not the work instruction distribution date and time is before the current processing date and time (step S201). If the work instruction distribution date and time is not before the processing current date and time (when "No" in step S201), the work instruction distribution unit 128 advances control to the next undelivered work instruction.

When the work instruction distribution date and time is before the processing current date and time (when "Yes" in step S201), the work instruction distribution unit 128 distributes the work instruction to the work subject according to the distribution method (step S202). Then, the work instruction distribution unit 128 determines that the work instruction has been distributed (step S203). That is, the work instruction distribution unit 128 distributes the post-setup work regardless of before or after the start time of the unprocessed process.

The above is the flow of work instruction distribution processing (periodic execution). According to the work instruction distribution process (periodic execution), the work instruction can be periodically distributed for the work whose work order distribution date and time is before the processing current date and time.

FIG. 15 is a flowchart showing an example of work instruction distribution processing (event execution). In the work instruction distribution process (event execution), for example, when one of the workers notifies the manufacturing record management device 210 of the work completion status from the worker terminal 220, the work instruction device 100 manages the manufacturing record as the record information 211. It is executed when it is delivered from the device 210. First, the work instruction distribution unit 128 processes each of the undelivered work instructions in steps S301 to S305 described later.

First, the work instruction distribution unit 128 identifies the undelivered work instruction of the work subject with the minimum date and time (step S301).

Then, the work instruction distribution unit 128 determines whether or not the undelivered work instruction can be specified (step S302). If the work order cannot be specified (in the case of "No" in step S302), the work order distribution unit 128 causes the work order creation unit 127 to recreate the work order (step S303), and returns control to step S301. ..

When the work instruction can be specified (in the case of "Yes" in step S302), the work instruction distribution unit 128 distributes the work instruction to the work subject according to the distribution method (step S304). Then, the work instruction distribution unit 128 determines that the work instruction has been distributed (step S305).

The above is the flow of work instruction distribution processing (event execution). According to the work instruction distribution process (event execution), the work instruction can be distributed at the timing when the work state is changed for the work whose work order distribution date and time is before the processing current date and time. That is, it is possible to provide a work instruction device having a shorter waiting time.

[Second Embodiment] Next, the work instruction system according to the second embodiment of the present invention will be described. In the second embodiment, when the work instruction device 100 receives the work refusal from the worker device 220 after delivering the work instruction to the worker device 220, the work instruction creation unit 127 cancels and rejects the work order. The work subject is excluded and the work subject is reassigned, and the work instruction distribution unit 128 distributes each time.

As described above, according to the work instruction device 100 according to the second embodiment, the waiting time until the work that occurs when the work instruction is given to the work subject who is in a state where the work cannot be started becomes a state where the work can be started. It is possible to provide a work instruction device with a shorter waiting time because it is possible to reduce the number of work instructions and give flexible work instructions according to the actual situation.
