DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work progress management method for supporting a work progress schedule and saving labor and rationalizing production management work, for example, in printing of packaging materials.

[0002]

2. Description of the Related Art Printing of packaging materials usually involves a variety of operations in which a printing process and a processing process are inseparably intertwined, and many of them are made-to-order and extremely diverse. The number of processes varies depending on the order (item), and the degree of difficulty in processing also varies. However, many machines are used in common and many materials are used in common.

[0003] In order to efficiently print such packaging materials and the like, each delivery time of incoming ordered products is satisfied while taking into account the production capacity of each section of the factory and the status of material arrival. It is necessary to create a schedule for each machine (horizontal split) by making a schedule. Conventionally, this set of progress schedules is called a stacking type, and based on a slip for each product name that printed out the order data, each department uses a computer to pile up data on the time axis,
It was common practice to shift the screen beyond the capabilities of the machine by moving the screen forward (landfall), and to create a horizontal schedule by hand based on that.

[0004]

[0006] As described above, when a set of scheduled progresses in printing of packaging materials and the like is performed in a piled manner, and a machine-specific schedule is created manually, it is necessary to use a slip once printed out. It takes time and effort to re-input data to each department's computer, and there is a problem that considerable skill is required for the pile-up and the subsequent relocation of the overflow (sloping down). There is a problem that it takes time and errors easily occur.
In addition, printing of packaging materials, etc., is a work with a very special character as described above, and there is a limit to the general method of stacking, and it is easy to manage the progress of vertical splitting for each item. Due to problems such as inability to perform, it is not possible to flexibly respond to a wide variety of user needs.

[0005] The present invention has been made in view of the above-mentioned problems, and it is possible to automatically make a scheduled progress set by utilizing order data of an existing system as it is.
It is another object of the present invention to provide a work progress management method capable of easily managing the vertical progress of each item in accordance with the schedule correction and capable of easily and efficiently creating an optimum progress schedule.

[0006]

A work progress management method according to the present invention comprises the steps of: taking out order data from an order data file comprising order-related data in the form of a quote detail;
Extracting the process data corresponding to the customer / item in the received order data from a process data file storing data such as process order, progress machine number, and the number of days required between processes for each customer / item; If there is no process data corresponding to the customer / item in the process, newly creating process data corresponding to the customer / item and putting the process data in the process data file, and storing the process data in the machine-specific operation data file Extracting the operation data for each machine, performing a scheduled assembly calculation based on the received order data, the process data, and the operation data for each machine to create the scheduled assembly data, and putting the created scheduled assembly data into the schedule data file It is characterized by comprising steps.

Here, the step of preparing the scheduled set data by performing the scheduled set calculation based on the received order data, the process data, and the machine-specific operation data includes the step of executing the first process by going back the required number of days from the scheduled delivery date. A first process start date setting stage in which a start date is calculated and a workable time frame closest to the start date is applied, and a first process start date set in the first process is set.
The steps in the second process start date setting step of calculating the second process start date by adding the travel time from the process to the second process and applying the closest workable date after the start date, and the methods in the above steps are repeated. In this way, it is possible to configure each stage of setting the start date of the third step and thereafter to set the start date of each step from the third step to the final step.

Further, in the work progress management method according to the present invention, the scheduled set data stored in the schedule table data file is taken out, and the scheduled set data after the correction is corrected by screen interactive format. A step can be added to put the data back into the schedule data file.

[0009]

According to the present invention, order data is taken out from an order data file consisting of order-related data in the form of quote details, and then data such as the order of processes, the machine numbers in progress, and the number of days required between processes for each customer / item. The process data corresponding to the customer / item in the received order data is extracted from the process data file containing the data, and if the process data corresponding to the customer / item does not exist in the process data file, the process data is newly added. Process data corresponding to the customer / item is created and put into the process data file, then the machine-specific operation data stored in the machine-specific operation data file is taken out, and then the order data and the process data And the above-mentioned machine-specific operation data, a scheduled assembly calculation is performed to create scheduled assembly data, and then the created schedule Set data is placed in the calendar data file.

Here, in the scheduled set calculation for creating the scheduled set data, as an example, the start date of the first process is calculated by going back the required number of days from the scheduled delivery date, and the closest work after the start date is possible. The time frame is applied, then
The moving time from the first process to the second process is added to the set start date of the first process to calculate the second process start date, and the closest workable date after the start date is applied, and then, The start date of each process from the third process to the final process is set by repeating the method of each stage.

Further, in the case where the schedule set data is changed, the scheduled set data stored in the schedule table data file is taken out and modified in a screen interactive manner, as an example. The schedule data is put back into the schedule data file.

FIG. 1 is a schematic diagram of a work progress management system in a printing section for producing food containers according to an embodiment of the present invention. This system supports a work progress schedule set by a work progress schedule set computer based on information such as order data received from a host computer. Do.

First, data necessary for a scheduled set such as order data is received from a host computer every day.

The host computer stores order data (order number, head / complete delivery date, product name, quantity, etc.), production data (production results, etc.), paper data (arrival date, etc.), cylinder data (plate cylinder management data). Various data are input by the existing system of production management. Then, the data from the existing system is transferred as it is online to a scheduled computer.

The scheduled computer processes the received order data and the like, and prints out various lists such as a section-specific hand-held list, a process file mismatch list, and a process file unregistered list.

The section-by-section hand-held list displays the hand-held items for each process in the order of the customer and the product name, thereby calculating and grasping the hand-held quantity, confirming the progress of the previous process, and checking the cylinders. Check the presence or absence of (plate cylinder), check the scheduled printing plate date, check the paper arrangement, check the paper arrival date, and review the operation plan.

The process file mismatch list is a list of reprint orders for items for which a process file has already been registered, and there are items (eg, the number of processes) in the contents of the registered process file that do not match the current order contents. Is displayed in comparison with the contents of the process file, and is used as a process file change registration input form when the process file is created.

The process file unregistered list is a list that displays the process order, the progress machine number, the number of aging days, and the like for a new order item for which a process file has not been registered.
After adding and correcting as necessary, it is used as a process file registration input form.

FIG. 2 shows an example of a process file unregistered list. The process file unregistered list shows items that are automatically set from order data and the like for each order item. As shown in the figure, the order number, customer, and product name (# numbers indicate what Indicates whether it is the first order received, eg, # 01 is a new product order), process number (010, 020,...), Process name (eg, GR
L: gravure printing), progress machine number, instruction (procedure) for the next process, aging days (ripening days), etc. are displayed. Here, the blank in the column of the aging days means that one day is left until the next step for the aging process. For example, if this column is 3,
4 days (1 day plus 3 days) before the next process. Further, when X is displayed in the X / Y column, the step and the next step (060 and 07 in the case of the example of FIG. 2) are performed.
0 means that two types of bonding AB and CD) are performed together by one machine. In this case, in the aging days column, the previous step (060) (zero aging days) is treated as having no column itself, and the aging days until the next step are displayed based on the subsequent steps (070). On the other hand, X /
When Y is displayed in the Y column, it simply means that the step and the next step are collectively performed without leaving for one day. In this case as well, it is assumed that there is no aging day column for the preceding process, and the aging process up to the next process is displayed based on the subsequent process. In the case of X display, for example, if the processing amounts of the two processes are each 1000 m, the total processing amount is also 1000 m. On the other hand, in the case of Y display, the work progress is different. If the processing amount of each process is 1000 m, the total processing amount is 1000 m
It becomes 2000m by x2.

Next, for a new product ordered item and a reprint ordered item with a partially changed order content, a process file for each item is created by inputting the progress machine number, process sequence, aging days, and the like.

This process file is created by screen input based on the above-mentioned process file mismatch list and the process file unregistered list which are added and corrected as necessary.

FIG. 3 is an example of a maintenance screen showing the contents of a process file. The meaning of each item in this screen display is the same as that in the process file unregistered list in FIG. These process files are managed by, for example, 15-digit numbers of the customer name code “9999001” and the product name code “888888888” shown in FIG.

Next, a vertically scheduled set calculation is performed for a new order or a reprint order. That is, using the process file, read the data on the efficiency of the machine and work from the machine file and machine-specific work file,
Based on the start date calculated backward from the delivery date of each item, the scheduled date and time of each process is set by searching for the existing gap.

In the case of this embodiment, the vertical division schedule calculation is as follows.
This is an automatic calculation process by a computer. An example of the specific procedure will be described based on the flowchart of FIG. S1 to S11 show each step of this flow.

Step S1 is a data reading step. First, newly received order data is read.

Next, steps S2 and S3 are steps for calculating man-hours. First, in S2, the required work time of each process is calculated and stored, and in S3, the required travel time between each process is calculated and stored.

Next, steps S4 to S6 are steps for calculating the first process temporary start date. First, in S4, the required number of days from the delivery date is traced back to the first process temporary start date by referring to the operation plan table of the production machine. In S5, it is determined whether the first process provisional start date is later than the last day of the range in which the schedule is already determined. The process proceeds to the step of setting the process start date. If the calculated temporary start date is before the last day of the scheduled confirmation range, the first in S6
The process provisional start date is set on the day following the final day of the schedule determination range, and the process proceeds to the first process start date setting step.

Next, step S7 is a step of setting the first process start date (scheduled work date). The process is referred to in the work schedule of the first process production machine, and the first process start date is set to one or more times. Search and apply the closest workable time frame (unscheduled frame).

Next, step S8 is a step of setting a second process provisional start date, in which the first process to the first process start date are set.
The temporary start date of the second step is calculated by adding the required travel time of the second step.

Next, step S9 is a step of setting a second process start date (scheduled work date). The step S9 refers to the work schedule of the second process production machine, and is set to one after the second process temporary start date. Search and apply the closest workable time frame (unscheduled frame).

Next, step S10 is a step for setting a start date (scheduled work date) of each step from the third step to the final step. By repeating the above steps S8 to S9, each step until the final step is performed. Set the start date for.

Next, step S11 is a step of setting a deliverable date, in which a required delivery work time is added to a scheduled final work day to calculate a deliverable date.

The scheduled date and time automatically set as described above are printed out as a list of date and time (temporary horizontal schedule) for each machine. This tentative schedule is used as a check sheet for correcting the schedule described later. Therefore, the planned printing date, the scheduled arrival date of the paper, etc. are displayed together for reference of the schedule correction work. If the delivery is expected to be delayed, a warning mark is displayed.

Next, the delivery date and the like are checked based on the tentative schedule, and a correction based on the check result, or a change due to intentional replacement of the progress schedule order or the machine number is performed in an interactive manner on the schedule correction screen.

Here, it is assumed that the schedule modification screen can display a horizontal split graph in which each man-hour of the existing schedule is arranged along the time axis for each machine as shown in FIG. Operations such as changing the scheduled progress order are performed by searching for an empty space in this graph. In addition, the schedule correction screen displays the provisional schedule of the machine number to be corrected, as well as reference information necessary for the schedule correction (scheduled plate date, paper arrival date, scheduled date of the previous process, progress results, etc.). Can be called and displayed on the same screen. Further, if there is a step that does not correctly enter between the pre-process scheduled date and the post-process scheduled date, a warning is issued by a change in display color.

After performing the above-mentioned schedule correction, a schedule table is called on the screen for the scheduled correction item, and the schedule table is printed out as a vertical division progress check table to check whether the process order is reversed or not. I do. Then, if reverse rotation or the like has occurred, the correction is performed again.

The above-mentioned schedule correction is performed for a fixed period (for example, for one week) by batch processing. If there is no problem in the vertical split progress check, a horizontal split schedule as shown in FIG. 6 is printed out as the main schedule, and work is performed according to the progress schedule. The progress schedule table shown in FIG. 6 displays the progress schedule in the order of the scheduled date and time by arranging three gravure printing machines.

In the above-described embodiment, the vertical division is performed by a computer, but the present invention is not necessarily limited to this.

[0039]

The present invention is configured as described above, and the order data of the existing system is utilized as it is by data transfer, and a process file is created for each item to enable a scheduled progression. The progress schedule can be automatically set, the schedule can be corrected in the interactive screen format, and the vertical progress management of each item can be easily performed, so that the optimum progress schedule can be created easily and efficiently.
