[Embodiment] An embodiment of a processing schedule creation device according to the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of a processing schedule creation device according to the present invention.

In FIG. 1, the processing schedule creation device according to the present invention is provided with a keyboard as input means 1 and a CRT as display means 7, and a processing schedule creation means 2, a first storage means 3, 2 The storage means 4, the comparing means 5, and the processing schedule adjusting means 6 are built in.

FIG. 2 is a block diagram of a processing schedule creation device according to the present invention.

An embodiment of the machining schedule creation device according to the present invention according to claim 3 according to claim 2 will be described.

The human power means 1 is, for example, the above-described keyboard, touch panel, or the like. Using this input means 1, the operator inputs a processing schedule.

The processing schedule creating means 2 creates a processing schedule which is not adjusted, but at least shows the working time zone of the worker. Here, the time zone includes the start time, the end time, and the time therebetween. When an NC machine tool processes a workpiece, the workpiece is attached to a jig, and further, the workpiece and the jig are attached to a pallet. The setup time of the setup work, which is the work of attaching the processing component, jig and pallet, the transfer time for transferring the processing component, jig and pallet to the NC machine tool, There is an exchange time for an exchange operation for exchanging a machined part with a conveyed machined part, and a machining time for an NC machine tool to machine the machined part. Of these times, the working time for the worker to perform work includes the setup time in the present embodiment. The transfer time is excluded from the worker's work time as work by the automatic carrier, and the replacement time is excluded from the work time for automatic replacement by the APC attached to the NC machine tool. Was excluded from the worker's work time as the work by automatic processing. It should be noted that it does not matter if the work time of the worker is delayed in the transport time, or the working time of the worker may be the work time. As shown in FIG. 3, this processing schedule indicates at least the working time zone of the worker. Specifically, 1
The transfer time zone, the work time zone of the operator, and the processing time zone of the jig and the processing component attached to the pallet are described in order. Next, when a machining schedule is created by the machining schedule creating means 2, the fourth
As shown in the figure, a first storage element included in the processing schedule creation means 2 in accordance with the processing scheduled order of the processing component,
The processing schedule creating means 2 creates a processing schedule with reference to the second storage element and the third storage element. As shown in FIG. 5, the first storage element stores a relationship between a jig attached to a pallet and a processed part attached to the pallet and the jig. As shown in FIG. 6, one pallet, one jig, and a work time attached to the pallet are stored. More specifically, focusing on the pallets, the exchange time of the transport time for each pallet and the work time of the worker is stored. Here, attention is paid to the pallet so that a plurality of jigs may be attached to one pallet. However, in the present embodiment, generally, only one jig can be attached to one pallet, so that is the case. As shown in FIG. 7, the third storage element stores the setup time and the processing time of the worker's work time for each processed part. Here, not all of the processing components that can be mounted on one jig are processed. This is because not all processing components that can be mounted on one jig are necessarily mounted. Therefore, the setup time and the processing time of the worker's work time are stored for each processing component without storing the worker's operation time and processing time for each pallet or jig. The processing time has some allowance.

The first storage means 3 stores the processing schedule created by either input by the operator using the input means 1 or use of the processing schedule creation means 2 for creating a processing schedule. , Specifically, RAM.

As shown in FIG. 8, the second storage means 4 stores the rest period of the worker.
It is. If the rest period varies from day to day, for example, a rest period per day for one month may be stored.

The comparing means 5 compares the working time zone of the worker of the machining schedule stored in the first storage means 3 with the rest time zone stored in the second storage means 4.

The processing schedule adjusting means 6 pays attention to the first overlapping time zone based on the comparison result by the comparing means 5 when the resting time zone and the work time zone of the worker overlap at a plurality of places, and calculates the overlapping time. The working schedule of the worker of the first working schedule and the subsequent working schedule is shifted after the break end time of the first overlapping break time zone, and the new working schedule of the worker of the working schedule adjusted once is adjusted. The work time period is compared with the rest time period stored in the second storage means 4. If the new work time period and the rest time period overlap, the work time period of the worker for the overlap time and the subsequent work time period The processing schedule is adjusted again by shifting the processing schedule after the break end time of the overlapping rest period, and the worker of the adjusted processing schedule is adjusted again. It is intended to adjust the schedule of working until there is no overlap with the break time zone and working time zone.

The display means 7 displays the processing schedule adjusted by the processing schedule adjusting means 6. Specifically, for example, the display on the CRT7 shown in FIG.
Alternatively, the operator is notified by printing with a printer.

Next, the operation of one embodiment of the machining schedule creation device according to the present invention according to claim 3 will be described.

First, the storage of the processing schedule in the first storage means 3 may be based on the input of the processing schedule by the operator using the input means 1. In this case, the operator creates a processing schedule and stores the result input by the input unit 1. In some cases, the processing schedule is stored in the first storage unit 3 by the processing schedule generation unit 2 generating the processing schedule. To explain this case, first, the operator inputs the planned processing order of the processed parts shown in FIG. Then, the processing schedule creating means 2 pays attention to the processing part number (5) of the first processing part in the scheduled processing order shown in FIG. 4, and the processing schedule creating means 2 has the first processing part shown in FIG. From the information that stores the relationship between the jig attached to the pallet and the processed parts attached to the pallet and the jig of the storage element, the jig to which the processed part of the processed part number (5) of interest is mounted To find out that the processed part with the processed part number (5) is attached to the jig with the jig number (1).
From the first storage element, the pallet to which the jig of the jig number (1) is attached is also the pallet number (1001).
Know that Next, processing schedule creation means 2
However, the processing component to be attached to the jig of the jig number (1) is checked from the processing components in the order of the processing scheduled input by the operator, and if there is a processing component to be attached, the component is attached. Specifically, the processing schedule creation means 2
It is known from the information of the first storage element shown in FIG. 5 that the processed part having the processed part number (5), (4), or (6) is attached to the jig of the jig number (1). By referring to the input result by the input means of the operator shown in FIG. 4, it is known that the processing part of the processing part number (4) can be attached, and the processing part of the processing part number (4) is first It will be attached together with the machined part of the machined part number (5) of interest. Then, from the information of the second storage element shown in FIG. 6 provided in the processing schedule creating means 2, the jig and the pallet number of the jig number (1) to which the processing part numbers (4) and (5) are attached Know the transfer time of 20 minutes and the replacement time of 10 minutes for the pallet of (1001). next,
From the information of the third storage element shown in FIG. 7 provided in the processing schedule creating means 2, the work time of the worker of the work part of the work part number (4) and the work part of the work part number (5) is obtained. Know that the setup time is 20 minutes each and the processing time is 10 minutes and 20 minutes respectively. When organized, the processing schedule creation means 2 processes the processing part number (4),
It is known that the processed part (5) is attached to the jig of the jig number (1) and is attached to the pallet of the pallet number (1001). Further, the processing schedule creating means 2 integrates the processing parts of the processing part numbers (4) and (5), the jig of the jig number (1), and the pallet of the pallet number (1001) from the above-mentioned time information. , Work time and processing time are calculated. In this case, specifically, the processing schedule creation means 2 first sets the processing time with the processing part numbers (4) and (5) (since 40 minutes and the replacement time is 10 minutes). Work time is 50 minutes in total. Further, the processing schedule creation means 2 sets the processing time to the processing part number (4),
The processing time of (5) is added to calculate 30 minutes.
Since the processing schedule creation means 2 has calculated the transport time (α), the worker's operation time (β), and the processing time (γ), the processing schedule is allocated to the processing schedule as shown in FIG. I do. Since the machined part with the machined part number (4) is machined together with the machined part with the machined part number (5), the machined part is removed from the input machining order. Also, if there is the same processing part in the processing order,
Give priority to the one with the earliest processing schedule. Then, the processing schedule creating means 2 focuses on the processing part (5) in the next scheduled processing order, performs the same calculation, and thereafter similarly creates the processing schedule shown in FIG. Subsequently, the processing schedule creating means 2 stores the processing schedule in the first storage means 3. Thus, the processing schedule is stored in the first storage unit 3.

Next, the comparing means 5 stores the working time zones of the respective workers in the machining schedule shown in FIG. 3 stored in the first storing means 3 and the second working means which are stored in the second storing means 4. Compare with the rest period shown in FIG. Specifically, as shown in FIG. 9 (a), the comparing means 5 compares the work time zone of each worker with the rest time zone. Then
You can see overlapping time zones. Then, based on the comparison result of the comparing means 5, the processing schedule adjusting means 6 determines that the rest time zone and the working time zone of the worker overlap at a plurality of places.
Focusing on the first overlapping time zone, the processing schedule is adjusted by shifting the worker's working time zone for the overlapping time and the subsequent machining schedule after the break end time of the first overlapping rest time zone. . Specifically, the processing schedule adjusting unit 6 focuses on the first overlapping time period of the plurality of overlapping time periods shown in FIG. 9A, which is the comparison result of the comparing unit 5. That is, as shown in FIG. 9 (a), the rest time zone (1) from 12:00 to 13:00, which is the first overlapping time zone, and 12:40
Attention is paid to a time zone in which the working time zone of the worker of the third processing unit from minutes to 14:00 overlaps, that is, from 12:40 to 13:00. The reason for focusing on the first overlapping time zone is that by adjusting the first overlapping time zone, it is conceivable that subsequent overlapping time zones will be resolved.
Here, the processing unit is the time required for the entire processing of one pallet, one jig, and the processing parts attached thereto, including the transport time, the working time, and the processing time. The first and second are attached
The order of the processing unit is shown. Next, as shown in FIG. 9 (b), the worker's working time zone for the overlapped time, that is, for 20 minutes from 12:40 to 13:00, and the subsequent processing schedule are shown in FIG. Shift after the break time). In this case, the start time of the working time zone of the worker of the third processing unit was 12:40, but the break time zone (1)
Start from 13:00 after the end of the break time. Then, the subsequent processing schedule is also shifted. Thereby, the processing schedule is adjusted. Next, the new working time zone (FIG. 9 (b)) of the worker of the once adjusted machining schedule is compared with the rest time zone stored in the second storage means 4, and the new working time zone of the worker is compared. When the work time period and the rest time period overlap, the work schedule is adjusted again by shifting the worker's work time period and the subsequent work schedule for the overlap time after the break end time of the overlapped break time period. That is, comparing the machining schedule after the first adjustment shown in FIG. 9 (b) with the rest time zone stored in the second storage means 4, the work time zone of the worker of the fourth machining unit and the rest time zone are compared. The time zone (2) and the working time zone of the worker of the fifth processing unit overlap with the rest time unit (3). Next, if attention is paid to the fourth processing unit and the rest time period (2), which are the first overlapping time periods, the transport time period does not require the worker's work as described above.
It doesn't matter if it's a break. Therefore, although the transport time zone of the fourth processing unit also overlaps with the break time zone (2), the transport time zone of the worker of the fourth processing unit overlaps with the break time zone (2). Yes, from 15:10
By setting the break time until 15:30 and shifting the work time zone of the worker for the overlap time and the subsequent processing schedule so as to start the work after the break end time of this break time zone (2), 9 As shown in FIG.
The processing schedule adjusting means 6 adjusts the processing schedule. Next, the work time zone of the worker in the processing schedule after the second adjustment shown in FIG. 9C is compared with the rest time zone stored in the second storage means 4. Then, there is still an overlapping time zone between the worker's working time zone from 17:00 or 15:00 to 18:00 of the fifth processing unit and the rest time zone (3) from 17:00 to 17:30. Therefore, the processing schedule adjusting means 6 determines the time between 17:15 and 17:30.
The worker's work time zone for the overlapping time of the minute and the subsequent processing schedule are shifted to the break end time of the break time zone (3), thereby adjusting as shown in FIG. 9 (d). Then, the work time zone of the operator and the rest time zone of the processing schedule after the third adjustment shown in FIG. 9D are compared again. Then, since the overlapping time zone is eliminated this time, the adjustment by the processing schedule adjusting means 6 ends.

Next, the ninth, adjusted by the processing schedule adjusting means 6,
The display means 7 displays the processing schedule shown in FIG. Specifically, the worker is notified by, for example, the display on the CRT 7 shown in FIG. 1 described above or the printing by a printer. In this embodiment, the processing schedule is adjusted for one day. However, the processing schedule may be, for example, three days or one week. Further, in the present embodiment, the rest period of one day is set to three times, but may be one time or another number of times. Further, in the present embodiment, the processing unit has the order of the transport time, the operation time, and the processing time, but may be the order of the operation time, the transport time, and the processing time. In addition, the first adjustment may cause a new overlap at a time when there was no overlap initially,
The duplication can be eliminated as described above.

The present invention according to claim 1 compares the rest time zone stored in the second storage means 4 with the work time zone of the operator of the machining schedule created by the machining schedule creating means 2 by comparing In the case where parts overlap, the working schedule of the worker for the overlapping time and the subsequent working schedule are shifted after the break end time of the overlapping resting time zone, so that the working schedule can be adjusted. is there.

Further, according to the third aspect of the present invention, when the working time zone and the resting time zone of the worker overlap at one place, the overlapping time zone is adjusted after eliminating the overlapping time zone. This is an invention in the case where the adjusted processing schedule is compared and adjusted again when it occurs, and the comparison and adjustment are performed until there is no overlap.

The present invention according to claim 2 is an invention in a case where, when a work time zone of a worker and a rest time zone overlap at a plurality of locations, the adjustment is made by paying attention to the first overlapping time zone.

The processing schedule creation means 2, the comparison means 5, and the processing schedule adjustment means 6 may be realized by software using a microcomputer.
It can also be realized by a dedicated hardware circuit.
