Here, FIG. 10 shows a business plan processing flow according to the first embodiment. The business plan process is executed by the business management device 2 or the terminal 3. In step 31, the arrangement data is read. Specifically, the processing unit 21 of the business management device accesses the storage unit 26 of the business management device and reads the arrangement data created by executing the arrangement data creation program. In the first embodiment, when the arrangement data is created, the arrangement data is set to be automatically read. In addition, you may accept the instruction operation to read the arrangement data and read the arrangement data.

In step 32, the processing unit 21 of the business management device creates a business plan in which the arrangement data is assigned to the line based on the actual data which is an example of the actual information of the present invention, and displays it on the business plan screen. Data (attendance data, line data, product data, etc.) necessary for the above are appropriately read, and the created business plan is displayed on the display unit 24 of the business management device. FIG. 11 shows an example of the business plan screen according to the first embodiment.

First, the business plan for each line displayed at the bottom of the business plan screen of FIG. 11 will be described. A business plan is created by assigning arrangement data to a line based on actual data. Specifically, when the arrangement data is read, the processing unit 21 of the business management device accesses the actual data, and based on the product number of the arrangement data, the read arrangement data is lined (in FIG. 11 in FIG. 11). 1, 2A, 2B, etc.) are assigned. In the first embodiment, the product number and the line are associated with each other on a one-to-one basis, and when the arrangement data is read, the read arrangement data is assigned to the line according to the order in which the arrangement data is read and the delivery date. The arrangement data corresponds to a plurality of rectangular squares arranged at the bottom of the screen in FIG. 11, and is displayed vertically arranged for each line arranged in the horizontal direction. The product number and the line may be associated with each other on a one-to-many basis. In this case, the priority of the line is set, the arrangement data is first assigned to the line of the first priority, it is judged whether the delivery date is exceeded in the assigned line, and if it is exceeded, the arrangement is made to the line of the second priority. Data may be assigned. Whether or not the delivery date is exceeded can be determined by accumulating the estimated processing time for each arrangement data, calculating the estimated completion time, and comparing it with the delivery date. Alternatively, the arrangement data may be assigned to a plurality of lines, the estimated completion time of the product on the assigned line may be calculated, and the arrangement data may be finally assigned to the line having the earliest estimated completion time.

The line is arranged horizontally, and the worker in charge of the line, today's overtime hours of the worker, and the estimated time of the product in production are displayed at the upper part of the line. The worker's attendance data (attendance information) is recorded in the storage unit 26 of the business management device (not shown), and today's work time of the worker is displayed based on the attendance data. Today's overtime hours for workers are calculated by subtracting the estimated processing time (calculated based on actual data) for products scheduled to be produced today from today's working hours calculated from attendance data. When the overtime hours exceed the specified hours, for example, they are displayed in red, for example, in distinction from other areas of overtime hours (see line 3). The predicted time is calculated by subtracting the actual working time (time obtained by subtracting the current time from the production start time) from the machining predicted time calculated based on the actual data. When the predicted time exceeds the machining predicted time calculated based on the actual data, it is displayed in red, for example, in distinction from other predicted time regions (see line 1). In addition, for example, when a worker is absent, a planned suspension is displayed (see line 4A). When a plurality of workers are engaged in the line, for example, a plurality of workers may be displayed, or only a representative may be displayed. The number of lines is not particularly limited, and if the number of lines does not fit in the screen, it can be displayed by scrolling a scroll bar (not shown) in the horizontal direction.

The rectangular mass is an example of the arrangement small area of the present invention, corresponds to the arrangement data and the arrangement card, and includes the product number (product number), quantity, delivery date, start time (production start time), and the like. The rectangular squares are displayed vertically side by side for each line (for each production lane). The completion mass (an example of the completion arrangement small area) at the top is the product data of the product whose production has been completed. Product data of products whose production has been completed is accumulated, and the completed cells can be displayed by scrolling a scroll bar (not shown) in the vertical direction. The second mass in production (an example of a small area arranged in production) from the top is product data in production. The third and subsequent planned masses (scheduled small areas) are the product data of the products to be produced. Further, in the first embodiment, an interrupt data mass is provided (see line 4A). The interrupt data mass is a mass that can be arbitrarily set when it is desired to discontinue production on the line or when an urgent order is received. The interrupt data mass has a machining prediction time of 2 hours. By making it possible to arbitrarily set such a mass, it is possible to add a mass even when you want to stop production on the line or when an urgent order occurs, and the estimated processing time for each arrangement data for each line. Can be accumulated. The planned cell can also be displayed by scrolling a scroll bar (not shown) in the vertical direction.

The completed cells, the production cells, the planned cells, and the interrupt data cells are made so that they can be easily distinguished from each other, for example, the completed cell is gray, the producing cell is orange, and the interrupt data cell is black. The squares are displayed in different colors. In addition, a check box indicating whether or not the picking work is completed is displayed in each cell. When the picking work is completed and the barcode of the arrangement card (“parts arrangement card and receipt”) is read by the barcode reader 4, the check box is checked. For example, if there are two picking operations, two check boxes can be displayed. In addition, the selected cell is displayed in blue, for example, so that it can be easily distinguished from other cells (see the mass in production in lane 1). In addition, "plurality" in the square indicates that the square corresponds to two or more arranged cards. In addition, the colors of the characters displayed on the squares are also displayed separately. For example, black is standard, blue is multiple, and red is commented. Also, when the button for additional data today is selected, the vertically long area around the checkbox is displayed in, for example, emerald green so that the cells added today can be easily distinguished from other cells.

The detailed data of the selected square is displayed on the upper side of the line and near the center of the screen. When a cell is selected, the processing unit 21 of the business management device accesses line data, product data, etc., and as detailed data of the selected cell, the status, the movement line after stop, remarks, completion prediction, current time, The number of times of processing, the movement line after processing, the picking quantity, and the estimated processing time are displayed on the display unit 24 of the business management device. The status can display the current status of the line of the selected cell, for example, "0:", "1: Production stop (line stop)", "Production stop (improvement)" ( The display is omitted in FIG. 8). "0:" is the normal state, "1: Production stop (line stop)" is the instruction to stop the line and move to another line for production, and "Production stop (improvement)" is the line stop. Can be displayed. As for the movement line after stop, when the state is "1: Production stop (line stop)", the line after movement is displayed. As for the remarks, if additional information is set in the arrangement data, the additional information is displayed. The completion forecast is the date and time when the production of the product corresponding to the selected cell is completed. When the completed cell is selected, the date and time when the production is completed is displayed, when the mass being produced is selected, the date and time when the estimated machining time is added to the start time is displayed, and when the scheduled cell is selected, the current The date and time when the estimated machining time of the mass being produced and the estimated machining time of the scheduled mass are added to the time, in other words, the cumulative time of the estimated machining time since the production of the selected mass is displayed. When the estimated completion time exceeds the delivery date, it is displayed in red, for example, so that it can be distinguished from normal (for example, blue). The current time is the current time. The number of processes is the number of production processes for one production card. In the first embodiment, the arrangement card and the production process are usually in a one-to-one relationship, that is, one arrangement card product is produced on one line, but two arrangement card products are produced. It may be produced across lines. The number of times of processing is to call attention to such a case, and when the arrangement card and the production process are 1: 1, for example, "0/1" is displayed, and when the arrangement card and the production process are 1: 2. For example, "1/2" is displayed. As for the post-processing movement line, when the arrangement card and the production process are 1: 2, the line to perform the next production process is displayed. The picking quantity is the quantity of products of the selected order card for which the picking operation is performed. The number of cards is the number of arranged cards corresponding to the selected squares. Normally, there is a one-to-one relationship between a square and an arrangement card, but there may be one-to-many, and in the case of one-to-many, the number of arrangement cards corresponding to the square is displayed. In FIG. 8, "2 cards" is displayed in the number of sheets, and the total picking quantity of the two arranged cards is displayed in the picking quantity. The estimated machining time is calculated based on the past working hours of the product in the selected mass. When the estimated machining time exceeds the specified time (for example, 2 hours), it is displayed in red, for example, so that it can be distinguished from the case where it does not exceed the specified time.

Further, the processing unit 21 of the business management device further includes a number (NO.), A product number (product number), a product name, a control number, a processing number, a picking quantity, a shortage number, a delivery date, a completion prediction, a processing time, a picking standard, and the like. The work standard, part number master, configuration master, past tiger, daily report, and remarks are displayed on the display unit 24 of the business management device. In FIG. 11, since two arrangement cards are associated with the selected square, a product number or the like is displayed for each arrangement card. The number is the number of arranged cards. The product number is the product number of the product of the selected mass. The product name is the product name of the selected mass product. The control number is the identification number of the arrangement card. The number of processes is the quantity of products to be produced. The picking quantity is the quantity of products of the selected order card for which the picking operation is performed. The shortage number is the number of picking shortages, and is calculated by subtracting the picking quantity from the number of processed pieces. The delivery date is the delivery date of the selected mass product. The completion forecast is the date and time of the completion forecast of the product of the selected mass. The processing time is the working time of the product of the selected mass. The picking standard displays or prints the specifications of the picking operation for the product of the selected mass. When the picking standard display is selected, the picking work specifications of the product of the selected mass are displayed, and when the picking standard print is selected, the picking work specifications of the product of the selected mass are printed. Will be done. The work standard displays or prints specifications for work on the product of the selected mass (eg, product assembly work). When the display of work standard is selected, the work specifications of the product of the selected mass are displayed, and when printing of the work standard is selected, the work specifications of the product of the selected mass are printed. .. The product number master is information on the product of the selected mass. When the product number master is selected, information on the parts that make up the product in the selected mass is displayed. The part information includes the part number, part name, and the like of the part. The configuration master is detailed information on the parts that make up the product of the selected mass. The detailed information of the part includes the part number, the part name, the material, the thickness, the width, the length, and the like of the part. When the configuration master is selected, detailed information on the parts that make up the product in the selected mass is displayed. The past tiger is information about troubles when producing a product of the selected mass. When a past tiger is selected, information about troubles when producing the product of the selected mass is displayed. It is also possible to display detailed information including images and the like. The daily report is the daily production report of the selected mass product. The remarks are additional information on the product of the selected mass, for example, "100% inspection" is displayed if 100% inspection is required.

In addition to the above, at the top of the business plan screen, complete, delete, execute, move, expand, combine, interrupt data creation, display, picking, picking 2, details, product name display, non-payment list, attendance, shortage list , In-production daily report creation, search, latest, etc., instruction buttons are displayed to accept instructions such as changes in business plans. When these instruction buttons are selected, the processing unit 21 of the business management device executes the function assigned to the instruction buttons. Each button is configured to execute a function by being selected after a cell for giving an instruction (change, etc.) is selected. The Finish button completes the square in production. The delete button deletes the selected square. The execute button executes the instruction. The move button moves the selected square. The expand button expands the selected square. The join button joins the selected square with other squares. The interrupt data creation button creates interrupt data. The display button returns to the state before the instruction. If the automatic update process is checked, the state before the instruction is automatically returned after 1 minute has passed. The automatic update time can be changed as appropriate. Picking displays a barcode reading screen. Picking 2 is used when there are two pickings (two stages). For details, the display of detailed information is omitted, and the vertical display area of the square is increased. In the product name display, the product name is displayed in the square. In this case, the display of the start time is omitted. The non-payment list displays a list of non-payment products. Attendance is editable by displaying an attendance calendar with working day dates, and when a date is selected, the lines, workers, and overtime hours on the selected date are displayed. The shortage list displays parts that are expected to be out of stock (parts that make up the product). In this case, the person in charge of operations in the previous process (for example, a material production factory) is notified. The daily in-production report produces a daily report of the products in production for the selected mass. The daily report is automatically created (for example, at 0 o'clock) when the work is completed (when the mass is completed), but when the work spans days, the daily report is created by selecting the daily report during production. Is possible. The search is to search the mass data by the control number, product number, etc. The latest is to update the business plan. If the automatic update process is turned on, the business plan is automatically updated, for example, at 1-minute intervals.

Further, below the above instruction button, automatic update processing, daily report automatic creation scheduled time, rest, all line today load, all line today capacity, line width initialization, and today additional data are displayed. If you check the check box, the automatic update process will be automatically updated and the automatically updated time will be displayed. The scheduled time for automatic daily report creation is the scheduled time for automatic daily report creation. For the holidays, the workers who are on holidays today are displayed. All line today load indicates today's all line load. The load for all lines today is displayed by subtracting (counting down) the time with the passage of time from the total machining time consisting of the estimated machining time. Today's ability for all lines indicates the ability for all lines for today, and is displayed by subtracting (counting down) the time from the total of today's attendance time with the passage of time. When the capacity for all lines today exceeds the load for all lines today, it is displayed in red, for example, so that it can be distinguished from normal (for example, blue). The width of the square can be adjusted arbitrarily, but if you select initialize line width, the width of the square will be initialized. Also, if you select the data added today, the data added today will be displayed.

In step 33, the processing unit 21 of the business management device accepts the change of the business plan. For example, when the instruction button is selected on the business management screen, the processing unit 21 of the business management device executes the function assigned to the instruction button. For example, by selecting the move button, selecting the square to move, and selecting the execute button, it is possible to move the selected square to an arbitrary line. Further, for example, by selecting the join button, selecting a plurality of squares to be joined, and selecting the execute button, the selected squares can be joined. "Multiple" is displayed for the combined cells, in other words, the cells to which multiple arrangement data are associated. Also, by selecting the expand button, selecting the cells that have already been combined, and selecting the execute button, the combined cells can be expanded. When a change is made to the square such as the movement of the square, the completion prediction is calculated based on the position of the changed square.

<Optimization process>
In the optimization process, the "time / piece" of the actual data used when calculating the estimated machining time is optimized. Specifically, when a predetermined number of actual data is accumulated, the processing unit 21 of the business management device repeats the optimization process of the actual data for selecting and correcting the actual data, and is based on the optimized actual data. To calculate the estimated completion time of the product. For example, when 10 "time / piece" of actual data are accumulated for the same product number, the processing unit 21 of the business management device selects 5 approximate "time / piece" values, in other words. Five values are grouped, and the average value of the selected (grouped) "time / piece" values is calculated. The "time / piece" used to calculate the average value is flagged as unusable. Next, when 10 "time / piece" of the actual data are accumulated including the average value of the "time / piece" value, 5 similar "time / piece" values are selected in the same manner. In other words, 5 values are grouped and the average value of the selected (grouped) "time / piece" values is calculated. After that, this process is repeated. The average value of the accumulated values is calculated until 10 "time / piece" of the actual data are accumulated. As mentioned above, the "time / piece" used to calculate the average value is flagged as unusable, but until 10 "time / piece" of the actual data are accumulated, the unusable flag is set. not stand. Further, when the processing unit 21 of the business management device improves the "time / piece" of the actual data by a predetermined ratio (for example, 5%) or more with respect to the current state as a result of performing the above optimization processing, the processing estimated time is set. Rewrite the "time / piece" of the actual data used when calculating. When the "time / piece" of the actual data is rewritten, the business management device 2 and the terminal 3 are notified. Further, when the "time / piece" of the actual data is reduced by a predetermined ratio (for example, 15%) or more with respect to the current state as a result of performing the above optimization processing, the business management device 2 and the terminal 3 are notified.

<Notification processing>
In the notification process, when a specific event occurs, the business management device 2 and the terminal are notified. Specifically, when the processing unit 21 of the business management device receives an order for the first product, receives an order for a product after a long time, a line abnormality occurs, receives an order for a past trouble product, or corrects attendance data. When the estimated processing time is rewritten, the business management device 2 and the terminal 3 are notified. In addition, the attendance data and the shortage list can be notified regularly (the attendance data is in the morning, and the shortage list is in the morning, noon, evening, etc.). Further, if a delay occurs in the business plan, for example, the next morning may be notified. As a result, further delay in business can be prevented. In addition, if there are any products that are due on the same day in the daytime and evening, notification may be given. As a result, it is possible to thoroughly prevent business delays. In addition, all-line today's load and all-line today's capacity can be notified on a regular basis (morning, noon, evening). As a result, it is possible to thoroughly prevent business delays.

<Effect>
According to the business management system 1 according to the first embodiment, a business plan is automatically created by the processing unit 21 of the business management device or the processing unit 31 of the terminal, in other words, the computer, so one paper order form is required. Compared to the case of manually making a business plan while checking one, the burden on the manager who makes a business plan can be reduced. Further, according to the business management system 1 according to the first embodiment, the cells corresponding to the arrangement card are displayed side by side in association with the line. Therefore, information such as whether the product has been produced, whether the product is in production, or when the product is produced can be easily grasped visually or intuitively by associating it with the line. In other words, the business plan and operating status of the line can be easily grasped visually or intuitively. In addition, since it becomes easier to make a shipping plan in the shipping business, which is the next process of the production business, the burden on the business of shipping the product can be reduced. Further, after the business plan is automatically created, the business plan can be manually changed as needed, so that the business plan can be changed according to the situation. In addition, the business plan can be changed by a simplified operation such as moving the mass.

In addition, the presence / absence of picking, the presence / absence of a product after a long absence, and the presence / absence of past tigers are displayed on the mass. By displaying the presence / absence of picking, it is possible to easily grasp the presence / absence of completion of the picking work. In addition, by displaying the presence or absence of products after a long time, it is possible to recognize products that are expected to be delayed in work compared to products that are regularly produced, and as a result, delays in work and mistakes can be detected. Can be reduced. In addition, by displaying the presence or absence of past tigers, it is possible to prevent the recurrence of troubles.

In addition, the business plan can be grasped by calculating the estimated completion time of the product based on the actual data. Further, by repeating the optimization process, it is possible to calculate a more accurate estimated completion time of the product, and as a result, it is possible to grasp a more accurate business plan.

In addition, it is possible to prevent work delays and troubles that may occur when receiving an order for these products by notifying the case of receiving an order for the first product, receiving an order for a product after a long time, or receiving an order for a troubled product in the past. In addition, by notifying when a line abnormality occurs, the business plan can be changed at an early stage, and work delays and troubles can be prevented. By notifying when the attendance data is corrected (for example, absenteeism or change in working hours), the work plan can be changed at an early stage, and work delays and troubles can be prevented. By notifying when the estimated processing time is rewritten, it is possible to inform that the productivity has been improved.

Further, the business management device 2 and the terminal 3 are connected to each other via the network N, and the business management device 2 and the terminal 3 have the same functions. Therefore, anyone with access authority can check and operate at any time to select a location. The terminal 3 can also be installed at the site. As a result, the worker's awareness of the work plan can be improved. In addition, the work efficiency of the worker who performs the next process (for example, shipping work) and related work (for example, picking work) can be improved.

In the optimization process, when a predetermined number of actual data are accumulated, the process of selecting and correcting the actual data is automatically repeated, but the optimization process may be performed by designating a period. Specifically, the period for which the optimization process is desired is manually specified. When the period is specified, the processing unit 21 of the business management device extracts 10 "time / piece" of old actual data in the specified period and selects 5 values of "time / piece" to be approximated. In other words, 5 values are grouped, and the average value of the selected (grouped) "time / piece" values is calculated. The "time / piece" used to calculate the average value is flagged as unusable. Next, the processing unit 21 of the business management device extracts 10 "time / piece" of the actual data newer than the previously extracted actual data, including the average value of the "time / piece" values, and similarly. Five similar "time / piece" values are selected, in other words, the five values are grouped, and the average value of the selected (grouped) "time / piece" values is calculated. After that, this process is repeated within the specified period.

Workers and equipment may change on the line. Therefore, for example, by designating the period after the change and calculating the estimated completion time calculated by performing the optimization process on the actual data after the change, a more accurate estimated completion time of the product can be calculated. As a result, it is possible to grasp a more accurate business plan. Further, for example, the expected completion time calculated by performing optimization processing on the past accumulated actual data and the estimated completion time calculated by performing optimization processing on the actual data in a manually specified period. It is also possible to compare.

Further, the arrangement data may include the presence or absence of the product after a long time in the process in addition to the presence or absence of the product after a long time. The product after a long time of the process is an example of the interval information of the present invention, and is information on whether or not the work interval of the worker has passed a predetermined period (for example, one month or more). The predetermined period can be set as appropriate. Further, the presence or absence of the product after a long time in the process can be displayed in the square displayed on the display unit 24 of the business management device or the display unit 34 of the terminal. Further, when an order is received for a product that has not been in the process for a long time, the business management device 2 and the terminal 3 may be notified. By displaying the presence or absence of products that have not been in the process for a long time, it is possible to recognize products that are expected to be delayed in work compared to products that are regularly produced, and as a result, work delays and mistakes are reduced. can.

The relay processing device 7 is connected to the production machine 5 and the Andon 6 and is connected to the network N to control the production machine 5 and the Andon 6 (for example, ON / OFF). Further, the relay processing device 7 functions as an edge computer that processes data (operation information (for example, ON / OFF information, welding gas pressure information, compressor pressure information)) from the production machine 5 and Andon 6. The relay processing device 7 can be configured by a computer, for example, a single board computer (for example, a raspberry pie) equipped with an ARM processor. Further, the relay processing device 7 stores an operating system and a program necessary for connecting to the business management device 2 and a plurality of terminals 3 to control the production equipment 5 and the Andon 6 and to realize data processing. ..

For example, the relay processing device 7 connected to Andon 6 acquires signals related to "part request", "supervisor call", and "picking error". More specifically, the relay processing device 7 connected to Andon 6 has ON / OFF signals (ON) of each hard button corresponding to "parts request", "supervisor call", and "picking error" installed on the line. -OFF information) is acquired, and the acquired ON / OFF information is transmitted to the processing unit 21 of the business management device or the processing unit 31 of the terminal. The button corresponding to "parts request" is a button for requesting a part when a part is insufficient. The button corresponding to "Call supervisor" is a button for calling a supervisor. "Picking mistake" is a button for notifying when there is a picking mistake. When these hard buttons are turned on, Andon's predetermined location lights up (not shown), and the display unit 24 of the business management device indicates that there was a "parts request", "supervisor call", or "picking error". Is displayed on the display unit 34 of the terminal. The indication that there was a "parts request", "call supervisor", or "picking error" will be described later.

Further, for example, the relay processing device 7 connected to the production machine 5 includes "welding operation" (an example of ON / OFF information), "CO ₂ (gas pressure)" (an example of welding gas pressure information), and "air (an example of welding gas pressure information). (Compressor pressure) ”(an example of compressor pressure information) is acquired, and each of the acquired information is transmitted to the processing unit 21 of the business management device or the processing unit 31 of the terminal. "Welding operation" is ON / OFF information of welding equipment. "CO ₂ (gas pressure)" is pressure information _{of gas (CO 2) of welding equipment.} "Air (compressor pressure)" is the pressure information of the compressor used in the welding equipment. When such information is acquired, the acquired information is displayed on the display unit 24 of the business management device and the display unit 34 of the terminal.

Here, FIG. 13 shows an example of the business plan screen according to the second embodiment. Hereinafter, the differences from the business plan screen according to the first embodiment will be mainly described. On the business plan screen according to the second embodiment, on a rectangular mass (an example of a small area arranged by the present invention), today's total operating rate for each line (31% in the leftmost example), current production. Equipment utilization rate of products (24% in the leftmost example), progress of current products (28/60 in the leftmost example), equipment operation display (fire in the leftmost example) "Mark), parts request, supervisor call, picking mistake information is displayed.

Today's total operating rate for each line is the operating time (elapsed time of work) of the equipment calculated from the welding operation signal acquired by the relay processing device 7 connected to the production machine 5, for example. Calculated and displayed by dividing. The equipment operating rate of the currently produced product is obtained by dividing the operating time of the equipment calculated from the welding operation signal acquired by the relay processing device 7 by the operating time (elapsed time of work) for the product being produced. Calculated and displayed. The progress of the current product is calculated and displayed by dividing the elapsed time by the estimated time for the product in production. The progress status of the currently produced product may be calculated and displayed by dividing the number of ON / OFF times by the quantity of the product to be produced based on the ON / OFF information of the equipment. On the equipment operation display, a "fire" mark (indicating that the welding equipment is operating) is displayed when the equipment is in operation, and a "hand" mark (manual work is in progress) when the equipment is stopped. Represents) is displayed. The mark can be changed as appropriate according to the equipment. Parts requests are indicated by a mark representing the cart. The component request changes color when there is a component request and blinks in green based on the signal acquired by the relay processing device 7 connected to the Andon 6. The supervisor call is indicated by a mark representing the supervisor. The supervisor call changes color when there is a supervisor call based on the signal acquired by the relay processing device 7 connected to Andon 6, and blinks in red. Picking mistakes are displayed with warning marks indicating picking mistakes. The picking error changes its color when there is a picking error based on the signal acquired by the relay processing device 7 connected to the Andon 6, and blinks in yellow. When a part request, a supervisor call, or a picking error is displayed blinking in each color, the line number also blinks in the same color. It should be noted that today's total operating rate for each line, the equipment operating rate of the current product, and the progress of the current product can be updated, for example, at 1-minute intervals. On the other hand, parts requests, supervisor calls, and picking mistakes are updated in real time.

In addition, gas and air are displayed in the upper right corner of the business plan screen. The gas is the pressure information of the gas (CO _{2) of the welding equipment.} Air is the pressure information of the compressor used in the welding equipment. For gas and air, green is displayed when it is normal, and red is displayed when it is not normal. If it is not normal, the business management device 2 and the terminal 3 are notified to that effect. The color is not limited as long as the condition of the equipment can be distinguished. In addition, the status of the equipment may be displayed in more detail in stages. Further, information other than gas and air may be displayed depending on the equipment.

In addition, "operation data" is displayed below the gas and air. When "Operation data" is selected, the operation waveform and operation history (log) of the selected line are displayed. The operation waveform and operation history are acquired by the relay processing device 7 connected to the Andon 6, signals related to "part request", "supervisor call", and "picking error", and the relay processing device connected to the production machine 5. It is composed of data based on signals related to "welding operation" (an example of ON / OFF information) acquired by 7. Here, FIG. 14 shows an example of the operating waveform according to the second embodiment. FIG. 14 shows the waveform and history of the operating status of the welding equipment. In the operating waveform, the horizontal axis represents time and the vertical axis represents ON (1) / OFF (0). The region (time zone) where the waveform interval is constant indicates that the welding equipment is turned on and off at a constant rhythm, and the work is proceeding smoothly. On the other hand, a region (time zone) where the waveforms are spaced apart indicates that a break or trouble has occurred. In the history, the line, welding equipment (operation / stop), value (ON / OFF), and time are displayed. By changing the "extraction condition" displayed on the upper left of the screen where the waveform is displayed, any of "part request", "supervisor call", "picking error", and "welding operation" can be performed on the selected line. The operating waveform and history are displayed. A threshold value may be set for the operation waveform and history, and when the threshold value is exceeded, the business management device 2 and the terminal 3 may be notified to that effect.

The business management system 1a according to the second embodiment can also obtain the same effect as the business management system 1 according to the first embodiment. Further, the business management system 1a according to the second embodiment is further provided with the production machine 5, Andon 6, and the relay processing device 7, so that the total operating rate for each line today, the equipment operating rate of the current product, and the current product are provided.

For example, the business management system 1a according to the second embodiment may further include an outside air temperature sensor that acquires the air temperature outside the factory building and an inside air temperature sensor that acquires the air temperature inside the factory building. Based on the air temperature information acquired by the outside air temperature sensor or the inside air temperature sensor, the estimated completion time calculated based on the estimated processing time or the estimated processing time may be adjusted. For example, in the case of summer, it is expected that the outside air temperature and the inside air temperature will be higher than in winter, and the working time will be longer. Therefore, for example, when the temperature is high, the processing prediction time and the completion prediction time may be longer than when the temperature is low. Further, for example, a variable for adjusting the machining prediction time and the completion prediction time may be set according to the season, and the variable may be multiplied by the calculated machining prediction time and the completion prediction time according to the season. .. This makes it possible to consider variations in productivity during the seasons (spring, summer, autumn, and winter). Further, as a result, the excessive work load of the worker can be reduced. In addition to outside air temperature and inside air temperature, information on humidity, atmospheric pressure, oxygen concentration, odor, dust, dust, welding fume, etc. is acquired by various sensors, and the state inside the factory is specified according to this information. Variables for adjusting the estimated machining time and the estimated completion time may be set according to the specified state in the factory. This makes it possible to consider variations in productivity depending on the conditions inside the factory. Further, as a result, the excessive work load of the worker can be reduced.

Furthermore, based on information such as temperature, humidity, atmospheric pressure, oxygen concentration, odor, dust, dust, welding fume, etc. in the factory, automatic opening and closing of ducts in the factory, automatic cleaning of ducts, automatic opening and closing of ducts and automatic cleaning of ducts May be recorded. Then, the status of automatic opening and closing of the duct and the status of automatic cleaning of the duct may be displayed on the display unit 24 of the business management device or the display unit 34 of the terminal. As a result, it is possible to easily visually or intuitively grasp the opening / closing status of the duct and the automatic cleaning status of the duct in relation to the progress status of the work. Further, when opening and closing the duct, when automatically cleaning the duct, the business management device 2 and the terminal 3 may be notified.

Further, the business management system 1a according to the second embodiment may further include a blood pressure monitor, a thermometer, and the like. This makes it possible to manage the physical condition of the worker together with the product at that time. Further, the business management system 1a according to the second embodiment may further include a smart watch. According to the smart watch, it is possible to acquire the operator's pulse, body temperature, blood pressure, position information, and the like. In addition, it is possible to notify the smart watch of the presence or absence of a product after a long absence. By providing a smart watch, it becomes possible to easily manage the physical condition of the worker together with the product at that time.

Further, the business management system 1a according to the second embodiment may further include an AR device. The AR device preferably has functions such as barcode reading, AR, a camera, voice recognition, and a motion sensor. For example, by displaying the standard document, the standard document can be made paperless. As a result, quality and productivity can be improved by making mistakes in standard documents and making them wearable. Further, by equipping the AR device, when a trouble occurs, the operator can give a remote work instruction. Further, if a defective product occurs, an image may be acquired by the camera and the same defect may be notified by image recognition. As a result, the occurrence of defective products can be suppressed.

Further, the business management system 1a according to the second embodiment may include a mold, a pallet, an IC tag fixed to the actual product slip, and an IC tag reader that reads the IC tag. The IC tag may be a metal IC tag. As a result, for example, an IC tag reader can simultaneously recognize a plurality of actual product slips, which saves labor and improves accuracy. Further, the position information may be acquired from the IC tag to manage the mold, the pallet, the shipment, and the like. Further, the layout diagram may be displayed for the mold, the pallet, etc. based on the position information. Further, by adopting the IC tag as an internal embedding type, it is possible to protect the IC tag from dirt on the outer surface and the like. The IC tag may be embedded in the worker's name tag or employee card. As a result, the position information of the worker can be acquired, and the arrangement status and the movement history of the worker can be managed.

In addition, the arrangement data can further include the first process newcomer, the second process newcomer, and the third process newcomer, in addition to the presence or absence of the product after a long absence. The first process rookie to the third process rookie are information on the number of times the worker has experienced producing the corresponding product. In addition to the presence or absence of products for the first time in a long time, the first process rookie to the third process rookie can be displayed on the display unit 24 of the business management device or the display unit 34 of the terminal. Further, when receiving an order for a product from the first process rookie to the third process rookie, for example, the business management device 2 and the terminal 3 may be notified at the start of work.

In addition, the arrangement data may include unofficial data, which is order data several months ahead. The unofficial data is created from the order data several months ahead, in other words, the provisional order data before the issuance of the purchase order, and can be distinguished from the arrangement data created based on the purchase order. The unofficial data is distinguished from the arrangement data in that it is provisional data, but basically contains the same information as the arrangement data. When there is a change in the provisional order data, the unofficial data may be changed (overwritten) based on the change in the provisional order data. If the contents of the purchase order and the provisional order data are different, the arrangement data may be changed based on the purchase order. The unofficial data includes the order date, product number, delivery date, quantity, issue classification, customer code, ordering party code, delivery date, quantity, issue date, presence / absence of a long-time product, presence / absence of past tigers, and the like. Then, the unofficial data can be created by executing basically the same processing as the arrangement data creation process for creating the arrangement data. For example, as the unofficial information data, the text data of the product number, the delivery date, and the quantity is extracted from the text file of the temporary order data, and is recorded as the unofficial information data in the storage unit 26 of the business management device. Further, as the unofficial data, the issue classification, the customer code, the arranger code, the issue date, the presence / absence of the product after a long time, the presence / absence of the past tiger, and the like are recorded in the storage unit 26 of the business management device. By including the unofficial data in the arrangement data, it is possible to easily visually or intuitively grasp the information such as the load and the overtime hours of the worker by associating it with the line even for several months ahead when the purchase order does not exist. ..

In addition to the business plan screen, the load and overtime hours may be displayed for each date and line. FIG. 15 shows an example of the prediction screen according to the second embodiment. FIG. 15 shows a part of the prediction screen. On the prediction screen, the load and overtime hours are displayed for each line, corresponding to the date. The load on the prediction screen is the work prediction time per day of the line, and is calculated based on the processing prediction time of the product to be produced. When the number of products to be produced is two or more, the estimated processing time of each product is added and calculated. The overtime hours on the prediction screen are the overtime hours per day of the line. The overtime hours on the prediction screen are calculated by subtracting the load, in other words, the estimated processing time of the product scheduled to be produced on the predetermined day, from the working hours on the predetermined day calculated from the attendance data. This makes it possible to visually and intuitively grasp the load and overtime hours for each line several months ahead. In addition, by selecting a cell that displays the load and overtime hours, the product number, product name, number of processes, picking quantity, shortage number, delivery date, and completion forecast are displayed at the top of the prediction screen as detailed information on the selected cell. Etc. are displayed. On the forecast screen, for the period in which the order data exists (for example, 1 to 2 weeks ahead), the attendance data, the load calculated based on the order data, and the overtime hours are displayed, and the order data does not exist and is unofficially shown. For the period in which the data exists (for example, 2 to 3 months ahead), the attendance data and the load and overtime hours calculated based on the unofficial data are displayed. In addition, the processing unit 21 of the business management device converts the delivery date, man-hours, and quantity from the past results into weekly and daily units, and in order to level the load for each line, the unofficial data is the experience value of the product to be produced. It is also possible to automatically distribute to the lines of the second to third candidates. Further, the overtime hours averaged over a certain period may be displayed in the mass in a visually easy-to-understand manner. In addition, it is preferable to calculate the overtime hours so as not to exceed the delivery date. Regarding the load, for the distribution line, for example, the priority of priority 1 to 3 is set, and the load is distributed to priority 1 first. If priority 1 has a higher load than others, priority 2 and 3 candidates It may be distributed to the line. The load displayed on the prediction screen and the overtime hours may be updated, for example, at 1-minute intervals. However, it is preferable that the attendance of the previous day is set to be delivered in advance, and in this case, the attendance data used for updating may be up to the information related to the attendance of the day before the previous day. If the load exceeds the predetermined threshold as a result of standardizing the load for each line and automatically distributing the load, the mass may be displayed in red, for example, and a notification that the load exceeds the predetermined threshold may be displayed. .. Further, for example, a day other than a working day (for example, Saturday) is set as a candidate day for an additional working day in the storage unit 26 of the business management device, and when the load exceeds a predetermined threshold value, the processing unit 21 of the business management device , The candidate date of the additional working day that does not exceed the delivery date may be selected, and the business management device 2 and the terminal 3 may be notified of the candidate date of the selected additional working day together with the fact that the load exceeds the predetermined threshold value. When a new working day is set, the processing unit 21 of the business management device may allocate the unofficial data to the new working day. Further, as a result of averaging the overtime hours for each line, if the overtime hours exceed the predetermined threshold value, the square may be displayed in red, for example, and a notification that the overtime hours exceed the predetermined threshold value may be displayed. ..

When the load and overtime hours are calculated based on the unofficial data, for example, the overtime hours based on the unofficial data are displayed as a part of the information of the attendance calendar. For example, when attendance is selected on the business plan screen, an attendance calendar in which the dates of working days are lined up is displayed. When a date is selected, the lines, workers, and overtime hours on the selected date are displayed and editable. In the displayed attendance calendar, for the period in which the order data exists (for example, 1 to 2 weeks ahead), the overtime hours calculated based on the order data are displayed, the order data does not exist, and the unofficial data exists. The overtime hours calculated based on the unofficial data are displayed for the period (for example, 2 to 3 months ahead).

Although the embodiments of the present invention have been described above, the business management devices and the like according to the present invention are not limited to these, and these can be combined as much as possible.

Further, in the embodiment, the process of creating the arrangement data and the process of the business plan are executed separately, but the process of creating the arrangement data may be incorporated into the process of the business plan.

Further, in the embodiment, the present invention has been described as an example in which the work of assembling work is managed in an automobile parts (product) assembly factory. It can also be applied to business management.
