<Embodiment 1>
For products with a strong design aspect such as crafts and clothing, some of the work for manufacturing the product may require manual work, that is, human work, which is the work carried out by humans. Here, the work and the process are substantially the same, and the same applies to the following description.

As an example that requires human work, it is assumed that the basic parts of a plurality of products are manufactured in common by machining, but some parts of each product are individually manufactured by human work. As another example, most processes can be realized by machining, but some processes require delicate manual work, or processes with little work record or unclear acceptance criteria. There are cases where the quality control process is performed manually.

Conventionally, various problems have arisen in the consignment production of products that require human labor. For example, when all processes are outsourced to an outsourcer, the outsourcer needs technology to carry out human work, so the outsourcer cannot be found, or the outsourced cost increases by the amount of that technology. There was a problem. In addition, for example, if parts and work-in-process manufactured by a contractor are mailed to the contractor and only human work is performed by the contractor, not only transportation costs are incurred but also the manufacturing period becomes longer. There was a problem that it would end up.

It is considered that the above problems can be solved if the outsourcer can carry out human work at the outsourcee by remote control such as work instructions. Especially in recent years, with the development of design digitization technology such as CAD (Computer Aided Design), it is possible to give work instructions for complicated shaped objects, and processing technology based on work instructions such as digital data of 3D printers etc. With the development, the processing range of the machine is expanding. In addition, with the development of ICT (Information and Communication Technology), progress confirmation of manufacturing process from remote location, confirmation of work quality at remote location by real-time communication such as image and voice, setting of robot master and slave The range of application of remote-controlled work with real-time characteristics, such as work input to manufacturing equipment via a network and direct instructions to workers, is expanding. In the future, it is expected that the consignment production of products that require human labor will expand by utilizing these technologies.

On the other hand, since the manufacturing equipment (production equipment) such as processing equipment used by the contractor is expensive, the contractor needs to contract from a plurality of contractors and operate the manufacturing equipment efficiently. In the manufacture of products whose design is controlled including the manufacturing process, the working time of each process is generally estimated in advance, and it is rare that the work fails in each process.

However, when the manufacturing of a product involves human work, for example, when the manufacturing of a product with a strong design aspect involves human work, if a defect occurs by human work, it is required to rework or remanufacture the work target. Therefore, it is not possible to properly estimate the work time of human work in advance. Furthermore, there may be restrictions on production resources such that human work can only be realized by full-time workers of the consignor because of high technical requirements or unclear work methods and work requirements quality.

Therefore, it is appropriate to prioritize human work in order to efficiently manufacture products that require human work by the consignor giving work instructions directly to the subcontractor's manufacturing equipment by remote control. Production scheduling is required. Therefore, the work instruction device according to the first embodiment described below can realize appropriate production scheduling in the manufacture of products that require human work.

FIG. 1 is a block diagram showing a schematic configuration of a work instruction device according to the first embodiment. The work instruction device of FIG. 1 is a device that gives a manufacturing work instruction to a manufacturing device such as a manufacturing facility that manufactures a product. The work instruction device of FIG. 1 includes a work plan input unit 1, a human work extraction unit 2, a connection work group setting unit 3, a work time estimation unit 4, a work order registration unit 5, and a connection work registration confirmation unit 6. And an automated work registration unit 7 and a work transmission unit 8. The work plan input unit 1 is included in the concept of the work plan acquisition unit, and the work order registration unit 5, the connection work registration confirmation unit 6, and the automated work registration unit 7 are included in the concept of the registration unit.

The work plan input unit 1 captures and acquires the work plan of the product. The work plan includes manufacturing information which is information on manufacturing of products, and the manufacturing information includes information for realizing each work (each process) and the like.

FIG. 2 is a diagram showing an example of a work plan according to the first embodiment. In the example of FIG. 2, a work plan of three types of products including a first product, a second product, and a third product is shown. Each work plan of the first product and the second product includes nine work processes (work), and the work plan of the third product includes seven work processes (work).

In the example of FIG. 2, the work processes of each product are shown in a row in a tentative order. However, if there is no order constraint between one work process and another work process, the order of one work process and another work process may be changed as appropriate, and one work process and another work may be changed as appropriate. It may be carried out in parallel with the process. For example, when two types of parts of a certain product are assembled in the front-end process and then the parts are combined in the back-end process, it can be treated as if there is no order restriction between the front-end processes of the two types of parts. can.

Information for realizing each work is necessary for carrying out the work, for example, part design information, part assembly information, inspection method, work procedure, and whether or not the work is human work. Includes information such as However, when the information for realizing each work includes the information indicating the human work, it is not necessary to include the information other than the information indicating the human work.

The human work extraction unit 2 of FIG. 1 extracts human work from the work plan imported into the work plan input unit 1. As described above, the work plan taken into the work plan input unit 1 includes information indicating whether or not the work is manual work. As for human work, for example, work performed by the consignor remotely because the work cannot be described as appropriate manufacturing information when consigning the work, or the worker of the consignee cannot perform the work based on the work information. Applies. Such work includes, for example, delicate adjustment or inspection in processing and painting, and work in which design information and inspection standards are unclear and the contractor makes a judgment based on actual images. Is assumed. The human work extraction unit 2 extracts all the human work included in the work plan.

FIG. 3 is a diagram showing an example of the result of extracting human work by the human work extraction unit 2. In the example of FIG. 3, the work marked with $, that is, work 1-2, work 1-6, work 2-7, work 1-7, and work 3-7 are extracted as human work.

Here, the work plan may include work that needs to be carried out before carrying out a certain work, such as a pre-process. For example, in the work of combining a plurality of parts, it is necessary to process the parts to be combined in advance.

The connection work group setting unit 3 of FIG. 1 extracts such work from the human work extracted by the human work extraction unit 2. That is, the connection work group setting unit 3 extracts the work that needs to be performed before the human work is performed from the work plan. Then, the connection work group setting unit 3 sets the connection work group of human work based on the extraction result.

The work that needs to be performed before performing the manual work may include only the direct work that needs to be performed directly before performing the manual work, or the direct work and the manual work are performed. It may include both indirect work that needs to be done indirectly before. The number of direct work may be one or more, and the number of indirect work may be one or more. For example, when the number of direct work is one and the number of indirect work is one, the work that needs to be performed before the manual work is performed is chained (serially) before the manual work is performed. ) Will include multiple tasks to be carried out. For example, when the number of direct work is multiple or the number of indirect work is multiple, the work that needs to be performed before performing the manual work is branched (parallel) before performing the manual work. It will include multiple tasks to be performed.

FIG. 4 is a diagram showing an example of the result of setting the connection work group by the connection work group setting unit 3. In the example of FIG. 4, the work marked with & is set as the connection work group. For the sake of simplification of the following description, for example, it is indicated that work 1-5 is a work that needs to be performed directly before performing work 1-6, and that work 1-5 is an input of work 1-6. It is sometimes written that it is a work that becomes.

In FIG. 4, for example, when work 1-1 is a work that is an input of human work 1-2, work 1-1 is set as a connection work group of human work 1-2. For example, when work 1-5 is an input for human work 1-6 and work 1-4 is an input for work 1-5, work 1-4 and work 1-5 are humans. It is set as a connection work group of work 1-6. For example, when work 2-3 and work 2-6 are operations for inputting manual work 2-7 and work 2-5 is work for inputting work 2-6, work 2-3, 2- 5 and 2-6 are set as a connection work group of manual work 2-7. In this way, the connection work group setting unit 3 sets the connection work group by performing the above extraction for each human work extracted by the human work extraction unit 2.

In the example of FIG. 4, human work 1-2, 1-6 are not in an input relationship with each other. That is, one man work 1-2 and man work 1-6 do not need to be carried out before the other man work is carried out, and one man work is a connection of the other man work. Not included in the work group. Therefore, the order of the manual work 1-2 and the manual work 1-6 can be changed as appropriate, and the manual work 1-2 and the manual work 1-6 can be performed in parallel. .. In the first embodiment, for the sake of simplicity, an example in which one man's work and the other man's work are not in an input relationship with each other will be described.

In addition, each connection work group described in the following description does not mean each of a plurality of works in one connection work group, but means the whole of a plurality of works in one connection work group. And. Further, the plurality of connection work groups described in the following description does not mean a plurality of works in one human work connection work group, but means a connection work group of a plurality of human work. ..

The work time estimation unit 4 of FIG. 1 calculates the work time of the connection work group and the work group instruction plan that defines the work order in the connection work group for each connection work group set by the connection work group setting unit 3. do. Since human work is not included in each connected work group in the first embodiment, the work time estimation unit 4 uses a predetermined work time calculation method to total the work time of each connected work group and the work group. The instruction plan can be calculated. As a predetermined work time calculation method, for example, there is a method of diverting the standard work time of each work known in advance, a method of estimating the work time with a simulator or the like, and the like.

In the first embodiment, when the same production resource such as the same machine or the same worker is used in a plurality of connected work groups, the work time estimation unit 4 produces the product among the plurality of connected work groups. The work time and work group instruction plan of each connection work group are calculated without considering the allocation of resources. On the other hand, when the same production resource is used in a plurality of operations in one connected work group, the work time estimation unit 4 considers the allocation of the production resource among the plurality of operations and considers the one. Calculate the working time of two connected work groups. For example, when the same machine is used in the plurality of operations even if the plurality of operations included in one connection work group are not in an input relationship with each other, the work time estimation unit 4 may perform the plurality of operations. The work time and work order are calculated on the condition that the work cannot be executed at the same time.

The work order registration unit 5 registers the work group instruction plan and the human work of the connected work group in the work instruction plan based on the work time calculated by the work time estimation unit 4. The work instruction plan is a plan that defines the order of work instructions to be transmitted to the manufacturing apparatus, that is, a plan that defines the work order. The work order registration unit 5 registers the connection work group in such a work instruction plan based on the work time calculated by the work time estimation unit 4, and thereby, the connection work included in the work instruction to the manufacturing apparatus. Order group instructions and manual work instructions.

In the work order registration unit 5 according to the first embodiment, the instruction of the connected work group having the shortest work time calculated by the work time estimation unit 4 and the instruction of the subsequent manual work are preferentially transmitted to the manufacturing apparatus. As such, the work group instruction plan and the human work of the connection work group are registered in the work instruction plan. When there are a plurality of connected work groups having the same work time, the work order registration unit 5 selects the connected work group based on a predetermined selection method and registers it in the work instruction plan. By repeating and, the instructions of a plurality of connection work groups are ordered. As a predetermined selection method, for example, there is a production scheduling method such as a method of preferentially registering a connected work group having a large margin of production resources.

The connection work registration confirmation unit 6 confirms whether all the connection work groups set by the connection work group setting unit 3 are registered in the work instruction plan. When the connected work group not registered in the work instruction plan remains, the work time estimation unit 4 recalculates the work time and the work group instruction plan of the connected work group not registered in the work instruction plan. Hereinafter, the work of the connection work group already registered in the work instruction plan will be described as "registered connection work group", and the work of the connection work group not registered in the work instruction plan will be described as "unregistered connection work group". do.

In the first embodiment, as described above, when the same production resource such as the same machine or the same worker is used in a plurality of connection work groups, the work time estimation unit 4 is used for the plurality of connection work groups. The work time and work group instruction plan are calculated without considering the allocation of production resources between them. Therefore, the work time estimation unit 4 calculates the work time and the work group instruction plan of the unregistered concatenated work group on the premise that the execution of the unregistered concatenated work group does not affect the execution of the registered concatenated work group. .. For example, on the premise that the production resources used in the registered concatenation work group during the execution of the registered concatenation work group cannot be used in the unregistered concatenation work group, the work time estimation unit 4 works on the unregistered concatenation work group. Calculate time and work group instruction plan.

Whether or not to order the execution of the unregistered concatenated work group that uses the same production resources as the registered concatenated work group before the execution of the registered concatenated work group depends on the work time and the calculation method of the work group instruction plan. For example, when calculating the work time and the work group instruction plan in consideration of the allocation of production resources of a plurality of concatenated work groups, the execution of the registered concatenated work group is performed on the premise that the execution of the registered concatenated work group is not hindered. Prior to that, the execution of unregistered concatenated work groups using the same resource may be ordered.

After the unregistered concatenated work group is confirmed by the concatenated work registration confirmation unit 6 and the processing returns to the work time estimation unit 4, the work order registration unit 5 performs the same processing as described above to generate the unregistered concatenated work group. Register in the work order plan. This series of processes is repeated until there are no unregistered concatenated work groups, that is, until there are no concatenated work groups registered in the work instruction plan. When the connection work registration confirmation unit 6 confirms that all the connection work groups are registered in the work instruction plan, the process shifts to the automation work registration unit 7. Hereinafter, the work other than the connection work group and the human work will be described as "remaining work".

The automation work registration unit 7 ranks the remaining work instructions included in the work instructions to the manufacturing apparatus by registering the remaining work in the work instruction plan based on a predetermined evaluation index. Predetermined evaluation indexes include, for example, well-known indexes such as the order in which work plans are registered, the order in which the time until all products are completed is the shortest, or the order in which production resources are available.

In the case of the first product of FIG. 4, the automation work registration unit 7 ranks the instructions of unconnected work 1-3, 1-7, 1-8, 1-9 without a $ mark or & mark. As a result, all the work included in the work plan is registered in the work instruction plan.

The work transmission unit 8 transmits a work instruction to the manufacturing apparatus based on the work instruction plan. The work transmission unit 8 basically transmits work instructions to the manufacturing apparatus in the order registered in the work instruction plan, but if specific conditions are given to the transmission timing, the work transmission unit 8 follows the conditions. For example, when there is another work that is an input of a certain work, the work transmission unit 8 waits for the completion of the other work and then transmits the work instruction of the certain work. For example, even if one work is waiting for work instruction transmission for another work registered earlier in the work instruction plan, the work transmission unit 8 can execute one work and another work in parallel. The work instruction of a certain work may be sent in advance.

In the first embodiment, when the work to be transmitted is a human work, the work transmission unit 8 notifies the consignor or the like of the work content and prompts the execution of the human work. The work transmission unit 8 gives a work instruction to the contracted worker for the work performed by the worker instead of the machine among the non-manual work.

The manufacturing equipment and workers of the contractor who received the work instruction carry out the work according to the work instruction from the work instruction device. When the work is completed, the work of the work plan is advanced by notifying the work instruction device of the work completion information. When all the work included in the work plan is completed, the work instruction device notifies the upper management system (not shown) that the work plan is completed and completes the process.

<Summary of Embodiment 1>
According to the work instruction device according to the first embodiment as described above, it is necessary for the human work extraction unit 2 to extract the human work from the work plan and to perform the work before the connection work group setting unit 3 performs the human work. A concatenation work group is set based on the extraction result of a certain work. With such a configuration, it is possible to give an appropriate work instruction to the manufacturing apparatus. For example, a series of work related to human work can be selected, and work instructions can be sent to prioritize the execution of those works. Therefore, it is difficult to estimate the work time, and the work that can be performed. It is possible to prioritize the work of people with limited personnel.

<Modified example of the first embodiment>
In the first embodiment, the work instruction of each work is transmitted after all the works included in the work plan are registered in the work instruction plan, but the work instructions are registered in the work instruction plan without waiting for the registration completion of all the works. Work instructions for the work may be sent. Such a configuration is realized with the same configuration as that of the first embodiment, except that the work transmission unit 8 is changed to transmit a work instruction before the registration of all the works is completed.

However, it may be more efficient to register (order) work instructions after monitoring the progress of work or the balance with other work plans. For example, when the progress of a specific work is delayed due to a work failure or the like and the work resource plan is deviated, it may be better to give priority to the work unrelated to the specific work. Therefore, the work time estimation unit 4 and the work order registration unit 5 may carry out the process based on the progress of the work. That is, instead of registering (ordering) all work instructions in advance, the work time estimation unit 4 and the work order registration unit 5 perform processing after waiting for registration in the work instruction plan until an appropriate timing. You may.

Appropriate timing for registration in the work instruction plan is, for example, when the number of human work waiting to be executed is less than or equal to the threshold value, when the number of work being executed is less than or equal to the threshold value, or when the work instruction is registered. In some cases, the number of works for which work instructions have not been sent in the plan is less than or equal to the threshold value.

Further, in addition to these operations, when the connection work group setting unit 3 or the like also performs an operation in which the work time is taken into consideration, the work time estimation unit 4 may treat the work time of the already completed work as 0. .. Further, an operation of appropriately deleting some untransmitted works among the works registered in the work instruction plan from the work instruction plan may be performed.

By the way, in the first embodiment, one man's work is not included in the other man's work connection work group, but one man's work may be included in another man's work connection work group. For example, when the connection work group includes human work, there is a method in which the work order registration unit 5 performs the same processing as in the first embodiment while substituting the work time of the human work with an appropriate time. As a method of setting an appropriate time as an alternative to the work time of human work, for example, a method in which a reference time is input in advance, or a work instruction device is based on the time of past actual work similar to human work. There is a method of setting an alternative time by AI learning or the like. When one person's work is included in another person's work connection work group, after the work time of one person's work is set by the above method, one person's work and the connection work group are of another person's work. The connection work group setting unit 3 resets the connection work group so that it can be used as the connection work group.

<Embodiment 2>
Depending on the work plan, it may be desirable to prioritize the work of a specific person over the work of another person. For example, there may be cases where one wants to perform manual work on another product after performing manual work to finish one product, or there is a case where one wants to perform manual work that is likely to fail before other human work. Therefore, in the work instruction device according to the second embodiment, the priority is set for the human work, and the connected work group of the human work is configured to be executed according to the priority.

FIG. 5 is a block diagram showing an outline configuration of the work instruction device according to the second embodiment. Hereinafter, among the components according to the second embodiment, the same or similar components as those described above will be designated by the same or similar reference numerals, and different components will be mainly described.

The configuration of the second embodiment is the same as the configuration in which the priority setting unit 11 is added to the configuration of the first embodiment (FIG. 1). The priority setting unit 11 sets the human work priority, which is the priority of the human work, for the human work extracted by the human work extraction unit 2. As this setting method, for example, a method in which a human work priority is set in advance in a work plan, or a method in which a work instruction device sets a human work priority from the order of past actual work by AI learning or the like. be. In order to prioritize the manufacture of a certain product, the human work priority may be set to be equal and high for multiple human work of a certain product, or to collectively carry out the same multiple human work of different products. , The human work priority may be set equally for those human work.

The work order registration unit 5 ranks the instructions of the connection work group included in the work instructions based on the human work priority and the work time of the connection work group described in the first embodiment. For example, the work order registration unit 5 first sends the instruction of the connection work group of the human work having a high priority of the human work and the instruction of the human work to the manufacturing apparatus with priority. Register the manual work in the work instruction plan. However, as in the first embodiment, the work order registration unit 5 gives an instruction to the connection work group having the shortest work time and a person following it to the human work having the same human work priority and the connection work group. The work instruction plan is registered so that the work instructions are preferentially sent to the manufacturing equipment.

According to the work instruction device according to the second embodiment as described above, the consignor sets the priority of the human work, so that the consignor preferentially executes the specific human work that the consignor wants to execute. be able to.

<Embodiment 3>
Since the work other than the human work can be carried out independently by the outsourcer, the priority is lower than the human work in which the outsourcer is restrained, and there is little problem even if the time to complete the work is long. Therefore, the manpower and its connection work group are carried out with a relatively large amount of production resources so that they are executed in parallel by a plurality of machines or workers, and the remaining work other than the manpower work and the connection work group is carried out with a relatively small production resource. The flexibility of production resources may be enhanced by such means as being carried out in.

FIG. 6 is a block diagram showing a conceptual configuration of the work instruction device according to the third embodiment. Hereinafter, among the components according to the third embodiment, the same or similar components as those described above will be designated by the same or similar reference numerals, and different components will be mainly described.

The configuration of the third embodiment is the same as the configuration in which the resource limit setting unit 12 is added to the configuration of the first embodiment (FIG. 1). The resource limit setting unit 12 sets a resource limit for limiting the allocation of production resources to the remaining work for the remaining work other than the human work and the connected work group extracted from the work plan.

The automated work registration unit 7 ranks the remaining work instructions included in the work instructions based on the resource limit degree. For example, the automation work registration unit 7 registers the remaining work in the work instruction plan so as to limit the instruction of the remaining work having a high resource limit more than the instruction of the remaining work having a low resource limit. For example, the automation work registration unit 7 limits resources so that the number of remaining work whose resource limit is equal to or higher than the threshold value and the number of human work other than the remaining work and the connection work group executed at the same time is equal to or less than the threshold value. The remaining work whose degree is equal to or higher than the threshold value is registered in the work instruction plan. As a result, the work transmission unit 8 is restricted from transmitting work instructions having a high degree of resource limitation.

According to the work instruction device according to the third embodiment as described above, the production resources are set by setting the resource limit while preferentially executing the human work and the connection work group as in the first embodiment. It can be used effectively.

<Embodiment 4>
Since the number of human work that can be performed at the same time is limited, there is little advantage if the manual work instructions are concentrated at a specific time and the number of human work waiting to be performed increases. It is desirable to formulate a work instruction plan with excellent other indicators such as the margin of production resources, while the appropriate number of work waiting to be carried out is secured. Therefore, the work time of the human work is predicted, and the instruction of the human work is ordered and the instruction of the connection work group is ordered so that the connection work group is completed by the time the predicted work time obtained by the prediction work time is completed. May be associated with.

FIG. 7 is a block diagram showing a conceptual configuration of the work instruction device according to the fourth embodiment. Hereinafter, among the components according to the fourth embodiment, the same or similar components as those described above will be designated by the same or similar reference numerals, and different components will be mainly described.

The configuration of the fourth embodiment is the same as the configuration in which the work margin setting unit 13 is added to the configuration of the first embodiment (FIG. 1). The work margin setting unit 13 predicts the work time of the human work extracted by the human work extraction unit 2, and sets the work margin, which is the predicted work time obtained by the prediction. As this setting method, for example, the work time is set in advance in the work plan, or the work instruction device sets the predicted work time from the past actual work time similar to the human work by AI learning or the like. There are methods and so on.

The work order registration unit 5 associates the ordering of human work instructions included in the work order with the ordering of the connected work group included in the work order based on the work margin. For example, assume that the man-operated work includes a first man-operated work and a second man-operated work to be instructed after the first man-operated work. In this case, the work order registration unit 5 sets the first according to the work margin of the first person work so that the connection work group of the second person work is completed by the completion time of the predicted work time of the first person work. The instruction of the manual work and the instruction of the connection work group of the second human work are associated and registered in the work instruction plan.

If the connection work group of the second person work cannot be completed by the completion time of the predicted work time of the first person work, the work order registration unit 5 sets the work time of the connection work group as in the first embodiment. Based on this, the instructions of the connection work group are ordered. That is, the work order registration unit 5 registers the connection work group having the shortest work time in the work instruction plan. When there is a connected work group of a plurality of man-made works having the same work time, the work order registration unit 5 sets the connected work group as a work instruction plan so that other indicators such as the margin of production resources are improved. To register with.

According to the work instruction device according to the fourth embodiment as described above, by setting the work margin, which is the predicted work time, the production resources are effectively utilized without affecting the human work of the consignor as much as possible. can do.

<Other variants>
