Abstract

PURPOSE:To automatically alter manufacture priority by always monitoring a progress advance situation including a waiting state in the respective processes of respective products and automatically treating the order of the waiting state in accordance with the sudden alteration of manufacture priority. CONSTITUTION:The respective products which are sequentially inputted to a manufacture line move the respective processes of A, B and C in an inputted order in a state where a manufacture priority alteration request is not inputted from a priority alteration input terminal 2. When a system moves from the waiting state to a starting state, the progress advance situation of the product concerned in a process progress advance situation memory 8 is updated. When the product priority alteration element of one product is inputted in such a state, a priority alteration request reception means 4 retrieves the progress advance situation of the product concerned. Then, the waiting priority of the product concerned in a process supply waiting product memory 6 is altered from low priority to high priority based on the retrieval. Thusd, the troublesome reconsideration of a plan before and after the product line supply of the product can be eliminated.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention, when production control of each process is performed in a production line such as a factory, changes in manufacturing priority order among products due to changes in order status or convenience of manufacturing site. The present invention relates to a manufacturing priority order changing device capable of automatically responding to the request under optimum conditions.

[0002]

2. Description of the Related Art Generally, one product is manufactured through a plurality of processes. Since the work content and the processing content are different in each process, the required time spent in each process does not match in each process, and when products with the same specifications are continuously input to the manufacturing line. Not necessarily. Therefore, for a process with a long required time, a plurality of products to be put into the corresponding process are in a waiting state. Further, when a process with a short required time is positioned after a process with a long required time, the process is placed in a product input waiting state.

Therefore, process control is performed so that each product input to the manufacturing line does not enter the waiting state before the process and each process does not enter the product input waiting state. In particular, in manufacturing plants, it is the highest priority to manufacture products on time and deliver them to customers.To achieve this, we have introduced a computer for production control and have made more detailed process control to secure delivery times. Need to do.

By the way, in recent years, when a disturbance factor that does not fit the original production plan occurs, such as a delivery time change request that suddenly occurs due to the customer's convenience or a revision of the production plan after the trouble of the equipment system at the manufacturing site occurs, There is a strong demand for swift and accurate response and the manufacture of products on time.

In response to this request, the current production line is
For products whose delivery time has been drastically shortened and which have not yet been put on the production line, re-establish the production plan. In addition, if the relevant product has already been put into the manufacturing line, the human system should know which process it is currently manufacturing, and give priority to the next process for other products. I have to. Moreover, even after the treatment of a sudden trouble in the equipment system, the operation of reassembling the manufacturing plan is performed on the spot by the judgment of the administrator.

[0006]

However, as described above, a production plan for each product is prepared in advance, and if the delivery date or the like changes after the actual production is started, the plan can be reconstructed or each process can be performed. The following problems occur in the method of changing the priority order of input by manual operation.

That is, it is necessary to completely reconfigure the plan before the product whose delivery date has been changed is introduced into the manufacturing line. However, this total reassembling work requires a great deal of time and labor and is urgent. There is a concern that it will not be in time.

Further, after the relevant product has been introduced into the manufacturing line, the plan change of the product after the introduction of the manufacturing line is executed according to the judgment of the manager of the manufacturing line. Also, the best choice is not always performed. Therefore, the accuracy of the judgment is insufficient, and it may not be possible to read the impact on the product to be changed and it may not be possible to secure the delivery date of the product, or the product may be mischievously made too quickly, resulting in other products. There is a concern that it will adversely affect the delivery time for.

The present invention has been made in view of such circumstances, and constantly monitors the progress status including the waiting state in each process of each product put on the manufacturing line to suddenly change the manufacturing priority order. By automatically rearranging the order of the waiting states in response to, it is possible to eliminate the complicated review of the plan before and after the product manufacturing line is introduced, and in consideration of the consistency with other plans, it is easy, accurate, and short time. It is an object of the present invention to provide a manufacturing priority order changing device capable of automatically changing the manufacturing priority order.

[0010]

In order to solve the above-mentioned problems, in the manufacturing priority changing apparatus of the present invention, a process input is performed in which each product on the manufacturing line is awaiting input for each process and is stored in the order of input. Waiting product memory, process in-process product memory that stores each product under process for each process, process progress status memory that stores process progress status including waiting status for each product, and each process is underway Process completion input terminal that outputs a completion notification when the process processing of the product is completed and also outputs a notification when the next product is started for the process, and the completion from the process completion input terminal In response to the notification and the input of the start notification, the progress status of the corresponding product in the process progress memory is updated. In the case of a completion notification, the progress information updating means for moving the relevant product from the in-process product memory to the next process in the process input waiting product memory and the product manufacturing priority change request are sent. A priority change input terminal to be inputted, and a priority change request receiving means for searching the process progress memory for the current progress status of the product corresponding to the manufacturing priority change request inputted from the priority change input terminal, The priority order change request receiving means detects the process progress status of the corresponding product and the priority order change registering means for changing the order of introduction of the corresponding products in the process introduction waiting product memory based on the priority order request. It is a thing.

[0011]

According to the manufacturing priority changing apparatus configured as described above, the products in the waiting state for the corresponding process are ranked and stored in the process waiting product memory for each process constituting the manufacturing line. Has been done. Similarly, the product under process in each process is stored in the product under process process memory.
Further, the progress status of the process including the waiting state for each product is stored in the process progress status memory.

In each step of the actual manufacturing line, when the processing step for one product is completed, the corresponding product is sent out and conveyed to the final position of each product waiting to be input in the next step. Then, the frontmost product, that is, the product with the waiting order of 0, which is lined up at the input waiting position of its own process, is taken in and the process processing is started.

The process arrival completion input terminal, for example, a manual device or an automatic operation from each process, notifies the completion of the processing process for one product for each process and a new product for each process. The start notification indicating that the processing step is started is output.

When the progress information updating means receives the completion notification designating the product from the process completion input terminal, the progress information updating means moves the corresponding product from the product memory in process start to the final order of the next process in the process waiting product memory. Further, when the notice of the start of designating the product is received, the corresponding product is moved from the process-waiting product memory to the same process in the process-starting product memory. Further, the progress information updating means updates the progress status of each product in the process progress status memory based on the completion notification and the start notification.

That is, which process is currently under way for each product inserted in the manufacturing line, which process is waiting to be loaded, and when it is in the waiting state, what is the order of loading? The condition of the turn is always known.

When a manufacturing priority change request for a product is input through the priority change input terminal, the priority change request receiving means retrieves the progress status of the product. Based on the retrieved progress status, the waiting order of the corresponding products in the process-waiting product memory is changed from, for example, lower order to higher order.

As a result, the corresponding product overtakes other products and is taken into the process first to start the processing process. Therefore, the waiting time is shortened, and as a result, the time required for the entire manufacturing of the corresponding product is shortened. In some cases, the priority may be intentionally lowered to intentionally lengthen the manufacturing period.

As described above, if the priority change request is input without artificially revising the complicated plan before and after the product is put into the line, it can be accurately and easily matched with other plans. In addition, it is possible to quickly change the priority order of the product group to be manufactured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the schematic arrangement of a manufacturing priority order changing apparatus of the embodiment. The manufacturing priority changing apparatus of this embodiment is roughly divided into a computer system 1 for executing various kinds of information processing, a priority changing input terminal 2 including a keyboard and a CRT, and a keyboard and a CRT. And the process completion input terminal 3.

In the computer system 1, three memories including a process-waiting product memory 6, a process-in-process product memory 7 and a process progress status memory 8 are configured by a hard disk device, for example. Furthermore, the priority order change request receiving means 4, 4 can be obtained by a software method such as a control program.
Priority change registration means 5 and progress information update means 9 3
Each means is configured.

For simplification of explanation, the manufacturing line to which this manufacturing priority changing apparatus is applied is divided into three processes, "process A", "process B", and "process C", as shown in FIG. It is assumed that the steps 10a, 10b, and 10c are arranged in order.

As shown in FIG. 2, in the process-waiting product memory 6, a product-waiting product region 6a is waiting for each process 10a, 10b, 10c to wait for the order of the process 10a to 10c. , 6b. 6c is formed, and the product number of each product is stored in each of the product-waiting product areas 6a to 6c. Specifically, for “process A”, three products are in the waiting state for loading. Then, when a plurality of products are in a waiting state, the “process A” is started in order from the product at the higher position. Therefore, in FIG. 2, the product with the product number "0006" is started in the "process A" with the highest priority (priority 0).

Similarly, in the product memory 7 under process start,
As shown in FIG. 2, in-process product areas 7a, 7b, and 7c are formed for each of the processes 10a, 10b, and 10c to store the products that are actually in process of the processes 10a to 10c. And in this Example, each process 10a-1
For 0c, the processing steps are executed on only one product at the same time, so that 1 is set in each of the in-process product areas 7a to 7c.
Only individual products are stored. For example, in the “process A”, the product with the product number “0005” is underway.

In the actual device, as shown in FIG. 3, the process-waiting product memory 6 and the process-in-process product memory 7 are put together into one memory area for each product number. Types of the processes 10a to 10b, a status indicating whether the process is in the waiting state (0) or in the process of starting (1), manufacturing information indicating a detailed processing procedure for the corresponding product, and 0 to 9 in the waiting state. The priority is stored.

In the process progress status memory 8, as shown in FIG. 4, for each product number of each product, a symbol indicating the process 10a to 10c to which the corresponding product currently belongs and the corresponding product in the process. The status indicating whether it is in the insertion waiting state (0) or in the process of starting (1) is stored. That is, the progress status of each product is stored in the process progress status memory 8.

Then, in each of the steps 10a to 10c of the manufacturing line having three steps shown in FIG. 2, when the processing step for one product is completed, the corresponding product is sent out, and each of the waiting steps for the next step is waited for. Transport to the final position of the product. Then, the frontmost product, that is, the product with the priority 0 is lined up at the input waiting position of its own process, and the process processing is started.

The process arrival completion input terminal 3 sends a completion notice designating a product in the computer system 1 when a processing process for one product is completed in each process by, for example, a manual device or an automatic operation from each process. To the progress information updating means 9. Further, the process completion input terminal 3 sends a completion notification designating a product to the progress information updating means 9 when the process starts a processing process for a new product in each of the processes 10a to 10c.

When the progress information updating means 9 receives the completion notice and the start notice from the process finish input terminal 3, the progress information updating means 9 changes the process start product memory 7 and the process introduction waiting product memory 6 according to the flowchart shown in FIG. Run.

First, the progress status of the relevant product is checked from the process progress status memory 8 (step S1). Then, the process to which the corresponding product belongs and whether it is in the process of starting or in a waiting state are confirmed. Next, the type of the input notification is checked (S2).

In the case of the completion notification, the product memory 7 under process start
In-process product areas 7a-7 of the corresponding steps 10a-10c
The relevant product is cleared from b, and the final product is stored in the final product position 6a to 6c in the product standby product memory 6 for the next process (S3 to S7).

Further, in the case of the start notification, the product waiting product area 6a of the corresponding process 10a to 10c of the product product waiting to be processed 6a.
Clear the corresponding products from ~ 6c, and start the process memory 7
In-process product areas 7a to 7 of the same process 10a to 10c
It is stored in b (S4 to S8).

Thereafter, the progress status of each product in the process progress status memory 8 is updated based on the completion notification and the start notification (S9). That is, when the completion notification is received, the process of the corresponding product in the process progress status memory 8 is advanced to the next process, and the status is changed from the start of 1 to the standby status of 0. Further, when the notification of the start of work is received, the status of the corresponding product in the process progress status memory 8 is changed from the wait for the input of 0 to the start of 1.

Therefore, the contents stored in the process progress memory 8 are always updated in accordance with the change in the operating state of one process 10a to 10c. That is, the latest process progress status is always stored.

A manufacturing priority change request designating a product from an external host computer is a priority change input terminal 2
When input to the priority order change request receiving unit 4 of the computer system 1 via the, the priority order change request receiving unit 4 determines from the process progress memory 8 to which process the corresponding product belongs, and in the corresponding process. Search for the progress status indicating whether it is in a waiting state or in a starting state. Then, the input manufacturing priority order change request and the progress status of the searched corresponding product are sent to the priority order variation registration means 5.

The priority change registering means 5 stores the product number of the corresponding product stored in the product waiting product areas 6a to 6c of the searched process in the process waiting product memory 6 based on the retrieved progress status. The waiting order is changed from, for example, lower rank to higher rank. It should be noted that the order may be lowered if necessary. Further, the priority order change registration means 5 may change the product number stored in the product memory 7 under process start, if necessary.

According to the manufacturing priority changing apparatus configured as described above, when the manufacturing priority changing request is not input from the priority changing input terminal 2, as shown in FIG. The products that are sequentially input move in the order in which the processes 10a to 10c of "process A", "process B", and "process C" are input. Then, even if each product is in the same process as the process, the progress status of the corresponding product in the process progress status memory 8 is updated when the product moves from the waiting state to the in-progress state.

Then, in this state, when a manufacturing priority change request for one product is input through the priority change input terminal 2, the priority change request receiving means 4 retrieves the progress status of the product. .. Based on the retrieved progress status, the waiting priority order of the corresponding products in the process-waiting product memory 6 is changed from, for example, lower order to higher order.

As a result, when the process of one product is completed in the corresponding process and the process of the next product is started, the corresponding product overtakes other products and is taken into the process first. Therefore, the waiting time is shortened, and as a result, the time required for the entire manufacturing of the corresponding product is shortened. In some cases, when the shipping time is postponed and the storage space for finished products cannot be sufficiently secured, the priority may be appropriately lowered to intentionally lengthen the manufacturing period.

As described above, as long as a manufacturing priority change request is input without the need for a human system to review a complicated plan before and after the introduction of a product into a line, it can be accurately and easily performed in conformity with other plans. In addition, it is possible to quickly and quickly change the priority order of the product group to be manufactured.

[0041]

As described above, according to the manufacturing priority changing apparatus of the present invention, the delivery schedule change request that occurs suddenly due to the customer's convenience, the review of the manufacturing plan after the trouble of the equipment system occurring at the manufacturing site, etc. Even if a disturbance factor that does not match the original manufacturing plan occurs, you want to change the manufacturing priority order without changing the complicated review plan before and after the product is put into the manufacturing line by the administrator. As long as the change request is input, it is possible to change the priority order of the product group to be manufactured accurately, easily and promptly in conformity with the production plan for other products.

Therefore, the change in the product plan after the introduction of the production line, which has occurred in the current production line due to the change in the production priority of the products, is not accurate due to the human judgment of the production line. It is possible to prevent the occurrence of problems such as being unable to read the impact on the products that are not subject to change and not being able to secure the delivery date of the products, or making the products too quickly than necessary.
