[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a standard work combination table creation system.
[0002]
[Prior art]
Conventionally, in factories, companies, etc., in order to standardize and manage various operations on product production lines, each work process is broken down into multiple work units, and the work time required for each work unit is combined. The standard work combination table displayed in the Gantt chart format is created.
[0003]
FIG. 2 is a diagram showing a conventional standard work combination table.
[0004]
In this case, one work process is divided into a plurality of work units, for example, 10 work units, arranged in the order of work, the work time required for each work unit is described, and the work time is displayed in the form of a Gantt chart. It is like that. Here, at the left end of the standard work combination table, a number indicating the order of each work unit, the contents of each work unit, and the required time of each work unit are displayed in the form of a table. In addition to the time required for manual work performed by the operator, the required time includes the time required for these operations as an automatic feed in the case of operations of assembly machines, processing machines, transport machines, etc. It is. Furthermore, when the worker needs to move to change the work place, the time required for the movement is included as walking.
[0005]
The required time is set in units of minutes or seconds based on experiments conducted in advance, past experience, or the like. In the standard work combination table shown in the figure, it is set in units of seconds.
[0006]
In addition, when creating a Gantt chart, a work bar that displays the required time for each work unit in length is described. First, in a row corresponding to the first work unit, a work bar having a length corresponding to the required time (2 seconds) of the work unit starting from 0 is described. Next, in the row corresponding to the second work unit, the position of the end point of the work bar corresponding to the first work unit is set as the starting point, and the time required for the second work unit (1.5 seconds) is handled. A working bar having a length is described. Then, by repeating the above-described operation, a Gantt chart as shown in the figure is created.
[0007]
If the time required for movement is included between each work unit, the movement is required between the end point of the work bar corresponding to the preceding work unit and the start point of the work bar corresponding to the subsequent work unit. Make sure to leave as much space as possible for the appropriate time. In addition, a remarks column is provided on the right side of the Gantt chart so that notes for each unit of work can be entered.
[0008]
With such a standard operation combination table, it is possible to accurately grasp the details of various operations in the product production line up to details. Therefore, it can be effectively used as basic data for rationalizing, reviewing and improving the work on the product production line.
[0009]
[Problems to be solved by the invention]
However, since the conventional standard work combination table is created manually by an operator, it takes a long time to create it. For this reason, when there is a change in the work content, or there is a change in the tact time as a take-up time per work in the subsequent work process, and it becomes necessary to recreate the standard work combination table, A person must spend a long time to re-create the standard work combination table, and overall, work efficiency is reduced.
[0010]
In addition, when the work contents are complicated, it is difficult to create an accurate standard work combination table by manual work. Therefore, an incorrect standard work combination table may be created in time.
[0011]
For example, in the case where the work includes an automatic work by an automatic machine that requires a reservation activation, a cycle time of a work unit performed by an operator and a cycle time of the automatic work by the automatic machine are shifted, It may take time from the start of work until the two cycle times are synchronized. Here, the automatic work by the automatic machine that requires the reservation activation is, for example, a processing station that automatically processes the workpiece on one side, and the worker mounts the workpiece at a position rotated 180 degrees from the processing station. This is an automatic operation by an automatic machine including a rotary table provided with a work mounting station. In this case, when the worker loads the workpiece at the workpiece loading station and presses the reservation start button, the rotary table rotates 180 degrees when automatic workpiece machining at the machining station ends, and the next workpiece Automatic machining starts.
[0012]
Here, at the time when the production line of the product starts operation, such as at the start of operation of the factory, there is no work in the processing station, so the worker attaches the first work and presses the reservation start button. When pressed, the rotary table immediately rotates 180 degrees and automatic machining of the workpiece is started. However, when the worker mounts the second workpiece, the automatic machining has not yet been completed, so even if the operator presses the reservation start button, it takes time to complete the automatic machining of the first workpiece. Take it. Therefore, the start of automatic machining of the second workpiece is delayed. That is, the cycle time of the automatic operation by the automatic machine is shifted. The cycle time is the time from the start time (end time) in one work process cycle regarding each work unit to the start time (end time) in the next work process cycle.
[0013]
On the other hand, the work unit at the work mounting station of the worker is usually the work detachment, and the previous automatically processed work is removed before the work unit for mounting the work is executed. For this reason, if the cycle time of the automatic work by the automatic machine is deviated, the operator cannot execute the unit of work in the work mounting station and waits, so the cycle time of manual work is deviated. End up. In addition, if the cycle time of the manual operation is shifted and the workpiece is quickly attached / detached, the automatic processing of the cycle is not completed yet, so the rotary table cannot be rotated, and the automatic machine The cycle time of automatic work will shift.
[0014]
As described above, when manual work by an operator and automatic work by an automatic machine are mixed in one work process, some work process cycles immediately after the start of operation of the production line are in an unsteady state. The cycle time for units continues to fluctuate. Moreover, since the shift of the cycle time of the unit of work by the manual operation and the shift of the cycle time of the automatic operation influence each other, the fluctuation of the cycle time has a complicated aspect and follows a simple gradual decrease curve. Not only when it converges.
[0015]
By the way, when creating the standard work combination table, the end point of the work bar of one work unit is set as the start point of the work bar of the next work unit, that is, the work time of each work unit is accumulated. To create. Therefore, it is normally created based on the start time of the first work unit of the first cycle immediately after the start of operation of the production line.
[0016]
However, as described above, when manual work by an operator and automatic work by an automatic machine are mixed in one work process, since several work process cycles immediately after the start of operation of the production line are in an unsteady state, It is difficult to create an accurate standard work combination table.
[0017]
The present invention solves the above-mentioned conventional problems, creates a standard work combination table for a plurality of work process cycles, and extracts a standard work combination table for work process cycles in a steady state. It is an object of the present invention to provide a standard work combination table creation system capable of creating a standard work combination table of contents easily and in a short time.

[0028]

The client 11 and the server 12 are communicably connected via the network 13.
[0029]
Here, the standard work combination table is for standardizing and managing various operations in the production line of the factory product, but in addition to this, research institutions, construction sites, shops, offices, financial In all organizations and private establishments such as institutions, schools, clinics, government agencies, local governments, companies, etc., prototype production, equipment testing, building construction, budget creation, inventory, accounting, purchasing, delivery, It can be used to manage all kinds of work such as document preparation, investigation, cleaning, etc. In the present embodiment, a standard operation combination table used for standardizing and managing various operations in a product production line in a factory will be described.

Further, the client 11 and the server 12 may be integrally configured. Further, the server 12 may be a single server or a distributed server in which a plurality of servers are organically coupled.
[0031]
Next, the standard work combination table will be described.
[0032]
FIG. 1 is a diagram showing a standard work combination table according to the embodiment of the present invention, and FIG. 4 is a diagram showing movements of workers on the production line according to the embodiment of the present invention.
[0033]
Generally, a product production line is composed of a plurality of work process cycles that are repeatedly executed, and each of the work processes is composed of a plurality of work units. In the present embodiment, as shown in FIG. 4, a work process cycle composed of six work units will be described. In the figure, the layout of the work stage in the work process is shown, the positions (1) to (6) indicate the place where each work unit is executed, and the number is executed for each work unit. Represents the order. A line connecting (1) to (6) is a trajectory where the worker walks and moves. Furthermore, XX256, XX2081, ◯ Δ1210, and △ Δ1280 are names of the respective work stages.
[0034]
Here, in order to standardize and manage various operations on the product production line, the standard operation combination table breaks down each operation process into a plurality of operation units, and combines the required operation time for each operation unit. Displayed in the form of a Gantt chart. The standard work combination table shown in FIG. 1 corresponds to the work process shown in FIG. In this case, the work process is divided into a plurality of, for example, six work units and arranged in the order of the work, and the required time in each work unit is described, and a length bar corresponding to the required time ( The bar is displayed in the form of a Gantt chart.
[0035]
On the left side of the standard work combination table, a number indicating the order of each work unit, the contents of each work unit, and the time required for each work unit are displayed in the form of a table. In addition to the manual work time required for the manual work performed by the operator, if the required time includes processing, transport, etc. by an automatic machine, the time required for the processing, transport, etc. is automatically sent. If the worker needs to move to change the work place, the time required for the movement is included as walking.
[0036]
The required time is set in units of minutes or seconds based on experiments conducted in advance, past experience, or the like. In the standard work combination table shown in FIG. 1, it is set in units of seconds.
[0037]
In the Gantt chart as the standard work combination table, a work bar is described as a bar for displaying the required time of each work unit in length. Here, in the Gantt chart, the horizontal axis is a time axis and the vertical axis is an axis representing a work unit. In the figure, each of the work bars is represented by a thick line extending in the horizontal direction. In this case, first, a work bar having a length corresponding to a required time (2.0 seconds) of the work unit starting from 0 is described in a row corresponding to the first work unit. Next, in the row corresponding to the second work unit, the second work unit is required with the position on the time axis corresponding to the end point of the work bar corresponding to the first work unit as the starting point on the time axis. A work bar having a length corresponding to time (2.0 seconds) is described. Then, by repeating the above-described operation, a Gantt chart as shown in the figure is constructed. Therefore, when the time required for movement is included between work units, the position obtained by adding the time necessary for the movement to the position on the time axis corresponding to the end point of the work bar is the time axis of the next work bar. Is the starting point.
[0038]
Here, when the time required for movement is included between the work units, the movement is necessary between the end point of the work bar corresponding to the preceding work unit and the start point of the work bar corresponding to the subsequent work unit. Make sure to leave as much space as possible for the appropriate time. For example, between the work unit (1) and the work unit (2), the worker moves from the work stage XX256 to the work stage XX2081. Therefore, the interval corresponding to the walking time (1.0 second) Try to free up. The walking time is represented by a bar composed of a dotted line extending in an oblique direction in the figure.
[0039]
Furthermore, the automatic feed time required for automatic feed by the automatic machine is represented by a bar consisting of a dotted line extending in the horizontal direction in the figure. In addition, the waiting time as the time for the worker to wait until the workpiece is transferred to the work stage by the automatic machine is represented by a bar composed of arrows extending in the horizontal direction in the figure.
[0040]
Here, it can be seen from the Gantt chart that the work stages ○ × 2081 and ○ Δ1210 include automatic work by an automatic machine that requires a reservation activation. The automatic work by an automatic machine that requires reservation activation is, for example, a work station in which a work station for automatically machining a work is provided on one side, and a worker mounts the work at a position rotated 180 degrees from the work station. This is an automatic operation by an automatic machine provided with a rotary table provided with a mounting station. In this case, when the worker loads the workpiece at the workpiece loading station and presses the reservation start button, the rotary table rotates 180 degrees when automatic workpiece machining at the machining station ends, and the next workpiece Automatic machining starts.
[0041]
In the work stage ○ Δ1210, the cycle time of the unit of work performed by the worker and the cycle time of the automatic operation by the automatic machine are shifted, so there is a waiting time for the time indicated by the arrow. I understand that.
[0042]
In the upper part of FIG. 1, a department code AA510 for identifying the department in charge of the work process, a line code BB1234 for identifying the production line, a part number 1234-567-890A for identifying the workpiece, and a part name XXXXX be written. Furthermore, the number of production per day is 1000, the number of production per shift in the case of shift work is 500, the take-up time per work in the subsequent work process, that is, the takt time is 40 seconds, The time required for one cycle of the work process is described as a cycle time of 40 seconds.
[0043]
With such a standard work combination table, it is possible to accurately grasp the details of the work process in the production line of the product up to details. Therefore, it can be effectively used as basic data for rationalizing, reviewing and improving the work on the product production line.
[0044]
Next, the operation of the standard work combination table creation system configured as described above will be described.
[0045]
FIG. 5 is a diagram showing a standard work combination table regarding a plurality of cycles of work processes from the start of operation of the production line in the embodiment of the present invention, and FIG. 6 shows the overall operation of the standard work combination table creating system in the embodiment of the present invention. FIG. 7 is a first flowchart showing the macro operation of the standard work combination table creation system in the embodiment of the present invention, and FIG. 8 is the macro operation of the standard work combination table creation system in the embodiment of the present invention. It is the 2nd flowchart which shows.
[0046]
First, a production line worker, administrator, etc. operate the client 11 to open a standard work combination table file, set variables such as scale intervals, and input a tact time. Next, the worker, administrator, etc. confirm the number of rows of the standard work combination table to be created, and confirm the sheet size of the worksheet for inputting the data of the standard work combination table.
[0047]
Subsequently, the workers, managers, etc. input data such as the order of each work unit, the contents of each work unit and the time required for each work unit, the time for automatic feeding, the time for walking, etc. into the worksheet. When the data input is completed, the button for starting the creation of the standard work combination table is pushed.
[0048]
Then, a command for starting creation of a standard work combination table is transmitted to the server 12 via the network 13, and the server 12 starts creating a standard work combination table. First, the tact time is input from the client 11 to the server 12, and then the data is fetched to start a cycle operation for creating a standard work combination table.
[0049]
First, the server 12 calculates a Gantt chart for the first work process cycle based on the start time of the first work unit of the first work process cycle immediately after the start of the production line operation. I do. In this case, the server 12 calculates the coordinates of the work bar in the Gantt chart corresponding to the start and end of the hand waiting time, the manual work time, the automatic feed time, and the walking time for the first work unit. Next, the server 12 determines whether or not the worker performs another work during automatic feeding by the automatic machine, and when the other work is performed, the automatic work by the automatic machine is further scheduled and started. It is determined whether or not the request is made. And when it is a request | requirement of reservation starting, the coordinate in the Gantt chart corresponding to the start and completion | finish of the said automatic feed time is calculated again.
[0050]
If the server 12 does not request reservation activation, the server 12 determines whether or not the automatic work by the automatic machine requires two workpieces to be attached. If it is required to attach two workpieces, the coordinates in the Gantt chart corresponding to the start and end of the automatic feed time are calculated again. Further, when it is not required to mount two workpieces, the server 12 determines whether or not the automatic operation by the automatic machine includes a special process. If the process includes a special process, the coordinates in the Gantt chart corresponding to the start and end of the automatic feed time are calculated again.
[0051]
Then, when the calculation for the first work unit is completed, the server 12 stores the result of the calculation and repeats the above-described operation to perform the calculation for the second and subsequent work units. In this case, the start and end coordinates of the work bar having a length corresponding to the required time of the second work unit are calculated starting from the position of the end point of the bar corresponding to the first work unit. Then, by repeating the above-described operation, the work bar of the Gantt chart as shown in FIG. 5 is determined.
[0052]
If the time required for the movement is included between the work units, the time required for the movement between the end point of the bar corresponding to the preceding work unit and the start point of the bar corresponding to the subsequent work unit. Leave only the corresponding length. For example, between the work unit (1) and the work unit (2), the worker moves from the work stage XX256 to the work stage XX2081, so that an interval corresponding to the walking time is provided. Since the walking time is represented by a dotted line extending in an oblique direction in FIG. 5, the start and end coordinates of the dotted line are calculated. .
[0053]
Furthermore, since the automatic feeding time by the automatic machine is represented by a dotted line extending in the horizontal direction in FIG. 5, the coordinates of the start and end of the dotted line are calculated. Further, the waiting time as the time for the worker to wait until the workpiece is transferred to the work stage by the automatic machine is represented by arrows extending in the horizontal direction in FIG. Coordinates are calculated.
[0054]
In the present embodiment, as shown in FIG. 5, the work process is composed of six work units, and therefore, the calculation is repeated until the calculation for the sixth work unit is completed. As described above, when the Gantt chart is created, the end point of the work bar of one work unit is set as the start point of the work bar of the next work unit. In other words, the work time of each work unit is accumulated to be created. Therefore, a Gantt chart is created with reference to the start time of the first work unit in the first cycle immediately after the start of operation of the production line.
[0055]
When the calculation for creating the Gantt chart for the first work process cycle is completed, the server 12 repeats the above-described operation to create the Gantt charts for the second and subsequent work process cycles. Perform the operation. In the calculation for creating the Gantt chart for the second and subsequent work process cycles, the server 12 performs the calculation based on the previous work process cycle. That is, the cycle time of each work process cycle is accumulated and created.
[0056]
When the calculation for one work process cycle is completed, the server 12 determines the coordinates in the Gantt chart corresponding to the start and end of all work units in the work process cycle in the previous work process cycle. It is compared with the coordinates to determine whether they are the same. If they are not the same, the calculation for the next work process cycle is performed, and if they are the same, the cycle calculation is terminated.
[0057]
By the way, at the start of factory operation or when restarting operation after a break, when an operator attaches the first workpiece to an automatic machine that requires reservation activation and presses the reservation activation button, for example, a rotary table The workpiece is automatically turned by rotating 180 degrees. However, since the automatic work is not yet finished when the worker mounts the second workpiece, it takes time until the automatic machining of the first workpiece is finished even if the worker presses the reservation start button. It takes. Therefore, the start of the automatic work of the second work is delayed. That is, the cycle time of the automatic operation by the automatic machine is shifted.
[0058]
On the other hand, the manual operation as a unit of work at the work station of the worker is usually detachment of the work, and the work that has been automatically machined one time before is removed before the work is mounted. For this reason, if the cycle time of the automatic operation by the automatic machine is deviated, the operator cannot perform the manual operation at the work station and waits, so the cycle time of the manual operation is deviated. . In addition, if the cycle time of the manual operation is shifted and the workpiece is quickly attached / detached, the automatic processing of the cycle is not completed yet, so the rotary table cannot be rotated, and the automatic machine The automatic feed cycle time will shift.
[0059]
As described above, in the calculation for creating the Gantt chart for the second and subsequent work process cycles, the cycle time of each work process cycle is accumulated and created. Therefore, when manual work by an operator and automatic work by an automatic machine are mixed in one work process, some work process cycles immediately after the start of operation of the production line are in an unsteady state, and each work unit is related to each work unit. The cycle time continues to fluctuate.
[0060]
In addition, since the shift in the manual cycle time and the shift in the automatic feed cycle time influence each other, the variation in the cycle time has a complex aspect and converges along a simple declining curve. Not only when. Therefore, as shown in FIG. 5, in order for a work process cycle to be in a steady state, a work process of several cycles or more is required from the start of operation of the production line.
[0061]
In the example shown in FIG. 5, since the work process cycles after the eighth cycle are the same, it can be said that the work process cycle is in a steady state in 8 cycles, but 10 or more work process cycles have elapsed. It may not be in a steady state until after.
[0062]
However, in the present embodiment, as described above, the coordinates in the Gantt chart corresponding to the start and end of all work units in one work process cycle are the coordinates in the previous work process cycle and the coordinates in the previous work process cycle. Repeat the calculation until they are identical. That is, the calculation is terminated when the contents of the standard work combination table for two consecutive work process cycles become the same. Therefore, when the coordinates in the Gantt chart corresponding to the start and end of all work units in one work process cycle are the same as those in the previous cycle, the work process cycle is in a steady state. The calculation is terminated when it is determined. In the example shown in FIG. 5, the calculation is completed in the ninth work process cycle, and the display device or printing device as the output device outputs the Gantt chart.
[0063]
As a result, manual work by an operator and automatic work by an automatic machine coexist in one work process, and even if a shift in the cycle time of manual work and a shift in the cycle time of automatic feeding influence each other, Thus, a Gantt chart for a steady-state work process cycle can be created.
[0064]
When the cycle calculation is completed, the server 12 displays the standard work combination table on the screen of the display device based on the result of the cycle calculation for the last work process cycle, that is, the work process cycle in a steady state. Or start a drawing process for printing on a medium such as paper. In this case, for the first work unit, the server 12 plots lines representing manual work time, automatic feed time, walking time, etc. on a table having a preset format, and performs the drawing process.
[0065]
Subsequently, when the drawing process for the first work unit is completed, the server 12 repeats the above-described operation to perform the drawing process for the second and subsequent work units. In the present embodiment, as shown in FIG. 1, the work process is composed of six work units, and therefore, the process is repeated until the drawing process for the sixth work unit is completed.
[0066]
When the drawing process for the work process cycle in the steady state is completed, the server 12 transmits the result to the client 11. Then, the worker, the manager, or the like displays the standard work combination table for the drawn work process cycle in a steady state on the screen of the display device of the client 11 or prints it on a medium such as paper. Can be output and used.
[0067]
