Abstract

PURPOSE:To make it possible to display a work instruction without inputting a finish of the work into a work record collection device in a previous process by providing the work record collection device with both a means for obtaining an earliest arrival time of a product and an arrival time table. CONSTITUTION:Contents of a card are inputted into a work record collection device 9 which checks a memory media 7 of an entire work process contents for existence of both a product code and a process code, and if they exist, existence of a process with which the inputted product is to be worked is checked. In case the result of the check shows that a next process is a subject of a process control, an earliest arrival time is made to be a total sum of minimum work times which have not been subjects of the progress control before plus a work finish time inputted first. Next, this earliest arrival time is transmitted to a device of the progress control to finish a handling. Then a work progress control device 8, receiving the information, corrects an arrival time table based on the earliest arrival time received.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a work progress management system, and particularly relates to a work progress management system suitable for managing work progress based on the collection results of work completion records. .

[Conventional technology]

In workplaces in the production sector of the manufacturing industry, such as machining workplaces, the order of processes or standard working hours often differ depending on the work involved, and the flow of workpieces is complex, making it extremely difficult to manage production. is difficult.

Therefore, conventionally, a work progress management device for collecting work results and issuing work instructions has been installed in every work process as described in Japanese Patent Laid-Open No. 59-45505.

The above-mentioned conventional technology has a problem in that when the production site is large and the number of work processes increases, the number of work progress management devices required increases and a huge amount of investment is required.

An object of the present invention is to provide a work progress management system that can reduce the number of work progress management devices while maintaining the same level of progress management function as when work progress management devices are installed in all work processes. 〇 [Means for solving the problem] The above purpose is to calculate the earliest arrival time to the subsequent process from the work completion record, minimum work time, and order in which the work is performed, and to use the arrival time table as a work record. The above object can be achieved by providing the work progress management device with means for displaying the products included in the arrival time table as ready for work at a time before the work instruction request time in addition to being provided in the collection device.

[Effect]

Based on the completion record of work processes input in predetermined time units, from the work order of completed products and the minimum work time in each process, from the work order of the product and the minimum work time in each process,
Next, the earliest arrival time to the process where the work progress management device is located is calculated and sent to the work progress management device to rewrite the contents of the arrival time table. As a result, when there is a request for work instructions in the work progress management device, products whose arrival time table has a time earlier than the time of the request are displayed as ready to start, so the work progress management device There is no need to increase the number of vehicles.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a block diagram showing one embodiment of the present invention.

A network provided in the local area network 12.

Each of the communication control devices 10 is connected to a work progress management device 8 and a work record collection device 9, respectively.

Both devices 8 and 9 are constructed using microcomputers, and work progress management device 8 includes an arrival time table 6 on memory.

The work progress management device 8 is a low force Lueriane,) Work 1
2, a control processing device 2 that controls each device in the device 8, a main storage device 3 that stores programs, and an output device 4 that displays processing contents on a CRT or the like.
, an input device 5 such as a keyboard, and an arrival time table 6
and an all-process work content storage medium 7 for storing the work content of all processes.

Further, the work record collection device 9 has the same configuration as the work progress management device 8 except for the arrival time table 6.

In FIG. 1, for convenience of explanation, two work progress management devices 8 and one work record collection device 9 are connected to a communication control device 10.
Although an example is shown in which mutual communication is performed between the devices M8 and M9, the number of devices can be arbitrary.

Next, an example of the processing of the work record collection device 9 will be explained based on the flowchart shown in FIG.

Several times a day, workers themselves or production site managers
Results are collected in real time.

Is it a card with work record information (product code, end time, work process code, etc.) completed in a work process other than the process? The operator then goes to the work record collection device 9 and inputs the work record. The process of collecting work results is as follows.

First, the device 9 that manually enters the contents of the card into the work record collection device 9 (step 21) checks whether the product code and process code exist in the all-process work content medium 7 (step 22). If not, return to input. next,
The product subjected to intervention in step 23 checks whether there is a next process to be performed, and if there is no next process, the process ends.

Car judgment that the next process is subject to progress management (
In the case of step 24), the process goes to step 27.

If not, go to step 25. In step 25, the minimum working time of the next process is added, the next process is replaced with the process for which the actual results have been input, and the process returns to step 25. In other words, investigate the next step.

If the next process is subject to progress management (step 24), the sum of the minimum work times for processes that have not been subject to progress management so far plus the work completion time input first The earliest arrival time for the process targeted for progress management is determined (step 27). Next, in step 28, the earliest arrival time is transmitted to the progress management process device, and the process is terminated.

The progress management device 9 that receives the information modifies the arrival time table based on the received earliest arrival time (step 29).

Next, an example of the processing of the work progress management device 8 will be explained based on the flowchart of FIG. 3.

First, as in the case of the work result collection device 9, results are collected (step 31).O Also, as a progress display function, progress by product and progress by process are displayed in step 32. Furthermore, for all products, compare the time in the arrival time table in the current work progress management device with the current time (
Step 33) If the current time is later,
Assuming that the product already exists, it is judged that it can be started (Step 34) 0 Among the products that can be started, it is output in the order of the closest delivery date or the shortest standard work time (Step 35) Then, the worker finally decides what to start. In other words, if the product has not arrived according to the contents of the arrival time table 6, work will be started on the product at that location.Information is transmitted to collect work results several times a day, such as 0 or more. By adding a function that predicts the arrival time of products in advance, it is possible to make it appear as if information and objects are synchronized and flowing as one. As a result, it is possible to obtain the same effect as collecting performance information in real time in all processes.

〔Effect of the invention〕

According to the present invention, by placing a work progress management device and a communication control device only in work processes that must be controlled for progress management, the number of devices can be reduced and the cost of the entire system can be reduced.

In addition, by introducing the product's earliest arrival time calculation method and arrival time table, work instructions can be displayed without inputting the completion of work in the previous process into the work record collection device.
Functions similar to those provided by providing a work progress management device for all processes can be achieved.
