FIG. 3 is a block diagram showing an electrical configuration of the work information collecting terminal 1. Reference numeral 10 denotes a key input unit including the above-described work key 5 and other various keys 6 to 9;
1 controls the operation of each part and measures and
CPU for performing calculations, 12 is a ROM for storing operation programs of the CPU 11, etc., 13 is a RAM for storing collected work information data, and 14 is a card for writing work information data to the memory card 3 (FIG. 1). The reader / writer 4 is the display unit described above. The CPU 11 constitutes an operation unit, and the ROM 12 and the RAM 13 constitute a storage unit.

FIG. 4 is a list showing an example of work contents, showing work items of a large classification, work items of a small classification included therein, and the contents thereof. The work items of the large classification are the work items displayed on the work key 5, and include “general work”, “process management”, “material management”, “preparation work”, “adjustment work”, “inspection work”, “incoming work”, and “trouble”. It consists of nine types of work of "equipment management". The work item of the small category is an item representing each work included in the work item of the large category, and includes various work contents as shown in the figure.

FIG. 5 is a diagram showing a data area in the RAM 13. In the RAM 13, corresponding to FIG.
An area is provided in which work items of the major category and the minor category are stored, and an area is provided in which the work time for each work item in the minor category and the total time thereof are recorded. However, the RAM 13 does not need to have all the work items as the area as described above, and may store only the input work item and the work time corresponding thereto individually.

Next, a procedure for collecting work information in the above system will be described. FIG. 6 is a flowchart showing a schematic procedure of work information collection in the work information collection terminal 1. First, the power of the work information collecting terminal 1 is turned on (step S1), and the memory card 3 is mounted on the slit 1a of the terminal 1 (step S2). The work information collection terminal 1 and the memory card 3 are given for each worker, and the memory card 3 has an ID number (for example, a name code) of the worker set in the memory 3a in advance. Thereby, it is possible to identify which worker the work data recorded on the memory card 3 belongs to. Instead of setting an ID number on the memory card 3, a numeric key composed of numeric keys may be provided on the work information collecting terminal 1, and an operator may input an ID number using this numeric key.

When starting the work, the worker presses the work key 5 corresponding to the work, selects a work item, and inputs a work item by performing an operation described later (step S3). After the work is started, each time one work is completed and the next work is performed, a work item is input.
4; NO) Repeat. In this process, the CPU 11 measures the time from one operation to the next operation, and automatically calculates the operation time. When the end key 8 is pressed after all the work in one day is finished (step S4; YES), the data of the work item and the work time are written in the memory 3a of the memory card 3 (step S5). Thereafter, the memory card 3 is removed from the slit 1a (step S6), and the collection of the work information for one day is completed. Here, the data is written to the memory card 3 when all the work is completed, but the data may be written in work units.

FIG. 7 is a flowchart showing details of step S3 in FIG. 6, and shows a procedure executed by the CPU 11. The CPU 11 monitors whether or not the work key 5 has been pressed (step S11).
Is pressed (step S11; YES), a large category of work item corresponding to the pressed work key 5 is displayed on the display unit 4 (step S12). FIG. 8 shows a display example at this time, in which the work item 4a of “inspection work” is displayed on the display unit 4 by pressing the work key 5 of “inspection work”. The display unit 4 also displays the current time 4b.

Next, it is determined whether or not the scroll key 6 has been pressed (step S13). If the scroll key 6 has been pressed (step S13; YES), the display unit 4 includes the work items of the large classification. The work items of the small classification to be performed are displayed one by one (step S14). FIG. 9 shows a display example at this time, in which the work item 4c of the first item, "acceptance inspection", among the small classification items included in the "inspection operation", is displayed. The display unit 4 also displays the work items 4d of the large classification.

Next, it is determined whether the scroll key 6 has been pressed again (step S15). Scroll key 6
Is pressed (Step S15; YES), Step S15
Returning to 14, the second work item of the small classification (for example, “stability check”) is displayed on the display unit 4. Thereafter, each time the scroll key 6 is pressed once, the work items of the small classification are sequentially updated and displayed on the display unit 4. Step S
If the scroll key 6 is not pressed in step 15 (step S15; NO), it is determined whether or not the input key 7 is pressed (step S16). If the input key 7 is not pressed (step S16; NO), It returns to S15.

Although the work items of the small classification are switched and displayed by operating the scroll key 6, the work items of the small classification corresponding to the work key are sequentially pressed by repeatedly pressing the work key 5. It may be displayed. In this case, when the work key 5 is first pressed, the work item of the large classification is displayed, and when the work key 5 is pressed again, the first work item of the small classification is displayed, and the work key 5 is pressed again. Then, the second work item of the small classification is displayed. Similarly, each time the work key 5 is pressed, the work item of the small classification is sequentially displayed. According to this, the scroll key 6 can be omitted, and the number of keys can be reduced.

The operator switches the display on the display unit 4 as described above, and selects a small classification work item corresponding to the work to be started. When the corresponding item is displayed, the user presses the input key 7 to input a work item. When the input key 7 is pressed (step S16; YES), the work item is determined, and the CPU 11 automatically measures the work time of the work from this point. This measurement is performed by, for example, CP
This is performed by a counter stored in U11. Alternatively, instead of this, the time at which the input key 7 is pressed may be monitored, and the work time may be measured from the difference between the times.

Thus, the CPU 11 measures the time from the input of a work item to the input of the next work item, and calculates the work time based on this time (step S17). The data of the calculated work time is stored in the area of the RAM 13 shown in FIG. 5 (step S1).
8). In this case, the work time data is stored in the work time area corresponding to the work item of the small classification. Also, the work times of the small categories are totaled, the work times of the large categories are calculated, and stored in the total time area.

As described above, in this embodiment, since the CPU 11 calculates the time from the input of a work item to the input of the next work item, the work item is selected when a new work is started. By simply pressing the input key 7, the operation time is automatically calculated and the operation becomes extremely simple. Here, the input key 7 is pressed at the start of each work, but the input key 7 may be pressed at the end of each work. In this case, a start key operated at the time of starting the first operation may be provided.

Although an example in which the operation time is calculated on the terminal side has been described here, this may be performed on the computer side. For example, in the work information collecting terminal 1, only the time at the time when the input key 7 is pressed is recorded as data relating to the work time, and the computer 2 which has received the data calculates the work time from the time difference. You may do so.

In the above example, work items of a small category are always input as work items. However, for example, in a manufacturing department, adjustment work and inspection work have a high weight, and process management and process control have to be performed. Since the specific gravity of material management and the like is low, there is little need to perform a detailed work analysis on such low specific gravity work. On the other hand, uniformly collecting detailed data even for work having a low specific gravity imposes an unnecessary burden on the worker. Therefore, instead of inputting the work items only in the small categories, the work items may be input in the large categories. According to this, efficient data collection according to the actual situation of the department can be performed. in this case,
In the work information collection terminal 1, for each of the major categories,
It is preferable to set in advance whether or not input is possible in the large classification. Further, this setting may be changed by key operation. Note that the work time when input is made in the large category is stored in the total time area in FIG.

The work item and work time data collected by the work information collection terminal 1 as described above are written into the memory card 3 as described above.
Is input to the computer 2 as a medium. FIG.
4 is a flowchart illustrating a procedure of data processing in the computer 2. First, the power is turned on to start the computer 2 (step S21), and then the memory card 3 is inserted into a card insertion slot (not shown) of the computer 2 (step S22). After the memory card 3 is set, the computer 2 reads the data recorded on the memory card 3 (Step S23), and performs a predetermined data operation based on the data (Step S24).
Then, a chart of the behavior analysis is created based on the calculation result (step S25). This chart can be easily created using, for example, commercially available spreadsheet software. The created chart is displayed on the monitor screen of the computer 2, printed by a printer (not shown) connected to the computer 2, and output as a report (step S26).

FIGS. 11 and 12 show examples of charts displayed or printed as described above. FIG. 11 is a behavior analysis graph (Pareto chart) relating to work items of a large classification, and shows the total time for each work of the entire section and the cumulative ratio. This graph is created by summing up the total time data obtained in FIG. 5 for all the workers. FIG. 12 is a table showing work time data for each of the work items classified into large categories, which is created based on the total time data obtained in FIG.

FIG. 11 shows an example of a behavior analysis graph in the manufacturing department. Since the ratio of “general business”, which should be low in the manufacturing department, is considerably high, the contents of this general business are not shown. Detailed analysis needs to be performed. Therefore, when the analysis result is output by the computer 2, by specifying an item that requires detailed data among the work items of the large classification, the work data of the small classification item included in the large classification is output. I have to. FIG.
3 is an example of the behavior analysis graph for the small classification items output in this way. Here, the total time and the cumulative ratio of the individual sub-categories included in the “general business” are represented in the same format as in FIG. Also, FIG.
The work time for each individual in the small classification is represented in the same format as in FIG. As described above, the work items are configured in two stages of the large classification and the small classification, and when detailed analysis is required, the work data of the small classification can be output, so that the optimum data according to the actual situation of the department can be obtained. Data is obtained.

FIG. 15 is a schematic configuration diagram showing another embodiment of the present invention. Here, a work information collection terminal 20 having a communication function is used, and the work information collection terminal 20 is connected to the computer 2 by a wireless LAN. 2
Reference numeral 1 denotes an antenna provided in the work information collecting terminal 20, 22
Is a communication device connected to the computer 2. The communication device 22 may be built in the computer 2.

FIG. 16 is a block diagram showing the electrical configuration of the work information collecting terminal 20. In the figure, the same parts as those in FIG. Here, instead of the card reader / writer 14 of FIG.
A communication unit 23 for communicating with the communication device 22 is provided. Reference numeral 21 denotes the above-described antenna.

According to this embodiment, the data collected by the work information collecting terminal 20 can be transferred to the computer 2 in real time via the wireless LAN. Also,
When a trouble occurs on a production line or the like, or when an abnormally long time is spent on a specific operation, it is possible to immediately send an alarm from the computer 2 to the operation information collecting terminal 20.

Further, as another embodiment of the present invention, it is conceivable to download data relating to the work schedule from the computer 2 to the work information collecting terminals 1 and 20 in advance. According to this, by comparing the collected work information with the work schedule, data (plan and actual data) indicating the schedule and the actual result can be created, and the management including the schedule can be performed. The data on the work schedule may be stored in the computer. In this case, the computer 2 creates forecast data.

In the above embodiment, the case where the system of the present invention is used for the purpose of grasping what kind of work the person has performed by paying attention to the person has been described as an example. Focusing on the product, it can also be used for the purpose of grasping what kind of work has been performed on the product. For example, in assembling an analyzer, the work information collecting terminals 1 and 20 of the present invention are installed beside the analyzer, and input to the work information collecting terminals 1 and 20 each time the analyzer is assembled. Then, using the collected data, a process analysis of the assembly of the product can be performed later.

Various embodiments of the present invention other than those described above are conceivable. For example, work information collection terminals include those that input data to a computer using a memory card or wireless LAN, those that are connected to the computer by a cable, and those that themselves are adapters and are directly attached to the computer. For example, various types of terminals can be employed.
