[Embodiment] An embodiment of the 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 machining schedule creation device according to the present invention is equipped with a keyboard as input means 1, a CRT as display means 7, and includes machining schedule creation means 2, first storage means 3, and 2 storage means 4,
Comparison means 5 and processing schedule adjustment 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 third aspect of the present invention, which is dependent on claim 2, will be described.

The input means 1 is, for example, the aforementioned keyboard, touch panel, or the like. The operator inputs a machining schedule using this input means 1.

The machining schedule creation means 2 creates a machining schedule that is not adjusted but at least allows the worker's work time zone to be known. Here, the time period includes its start time, its end time, and the time period between them. When an NC machine tool processes a machined part, the machined part is attached to a jig, and the machined part and the jig are further attached to a pallet. The installation of processed parts, jigs, and pallets in this way is work.The setup time for the setup work, the transportation time for transporting the processed parts, jigs, and pallets to the NC machine tool, and the installation time on the table of the NC machine tool. There is an exchange time for exchanging the machined part that is being processed and a machined part that has been transported, and a processing time for the NC machine tool to machine the machined part. Among these times, in this example, the setup time is given as the work time for the worker to perform the work. The transportation time is excluded from the worker's work time as work by an automatic guided vehicle, and the exchange time is N.
The processing time was excluded from the working time because it was automatically replaced by the APC attached to the C machine tool, and the machining time was excluded from the worker's working time because it was performed automatically by the NC machine tool. still,
It does not matter if the transport time overlaps with the worker's work time, and it does not matter if the processing time overlaps with the worker's work time.

As shown in FIG. 3, this machining schedule indicates at least the working time period of the worker.

Specifically, if one jig is attached to one pallet, you can focus on either one pallet or one jig, but in short, the transportation of the jig attached to one pallet and the processed parts The time zone, the worker's working time zone, and the processing time zone are listed in order. Furthermore, when one jig and one machined part are attached to one pallet, the machined part may be focused on and the machining schedule for the machined parts may be created.

In that case, it can also be said to indicate the worker's working time zone. Next, when the machining schedule creation means 2 creates a machining schedule, the machining schedule creation means 2 selects a The machining schedule creation means 2 creates a machining schedule by referring to the memory element, the second memory element, and the third memory element. As shown in FIG. 5, this first memory element stores the relationship between the jig attached to the pallet and the processed parts attached to the pallet and the jig. , as shown in FIG. 6, stores the transportation time for one pallet, one jig, and the processing parts attached thereto, as well as the replacement time within the worker's working time. Specifically, focusing on pallets, the transportation time for each pallet and the replacement time within the worker's working time are stored. Here, the reason why we focused on the pallet is to allow a plurality of jigs to be attached to one pallet. However, in this embodiment, since generally only one barrette jig can be attached, this is done.

As shown in FIG. 7, the third memory element stores the setup time and machining time of the worker's working time for each workpiece. Here, not all of the workpieces attached to the 5l jig are machined. This is because not all processed parts can be attached to one jig. Therefore, the operator's working time and machining time are not stored for each bullet or jig, but the setup time and machining time of the worker's working time are stored for each machined part. Also, the machining time is determined with some leeway.

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

As shown in FIG. 8, the second storage means 4 stores the break time period of the worker.
It is. Note that if this break time period differs from day to day, the break time period may be stored for each day of the first month, for example.

The comparison means 5 compares the working time period of the worker in the machining schedule stored in the first storage means 3 and the break time period stored in the second storage means 4.

Based on the comparison result by the comparing means 5, the processing schedule adjusting means 6 focuses on the first overlapping time period and calculates the amount of the overlapping time when the break time period and the worker's work time period overlap at multiple locations. The machining schedule is adjusted by shifting the working time period and subsequent machining schedule of the worker after the break end time of the first overlapping break period, and then the new machining schedule of the worker with this once adjusted machining schedule is The work time period is compared with the break time period stored in the second storage means 4, and if the new work time period and the break time period overlap, the work time period of the worker corresponding to the overlapping time and the subsequent time period are determined. The machining schedule is adjusted again by shifting the machining schedule after the end of the break of the overlapping break time period 411, and the overlap between the worker's work time period and the break time period in this re-adjusted machining schedule is eliminated. This is to adjust the machining schedule.

The display means 7 displays the machining schedule adjusted by the machining schedule adjustment means 6. Specifically, the operator is notified by, for example, the display on the CRT 7 shown in FIG. 1, or by printing on a printer.

Next, the operation of an embodiment of the machining schedule creation apparatus according to the third aspect of the present invention which is dependent on the second aspect will be described.

First, the first ilI[l! The processing schedule may be stored in the storage means 3 by inputting the processing schedule using the input means 1 by the operator. In this case, the operator creates a machining schedule and inputs the result using the input means 1, and stores the result. Further, the machining schedule may be stored in the first storage means 3 by creating the machining schedule by the machining schedule creating means 2. To explain this case, first, the operator inputs the scheduled order of machining of the parts to be machined, as shown in FIG. Then, the machining schedule creation means 2 focuses on the Kaloe part number (5) of the first workpiece in the order of scheduled machining shown in FIG. From the information in the memory element that stores the relationship between jigs that are attached to pallets and processed parts that are attached to the pallets and jigs, the jig to which the processed part with the focused processing part number (5) is attached is determined. As a result, we learn that the machined part with machined part number (5) is attached to the jig with jig number (1). Then, from this first memory element, this jig number (1
) is installed, and the pallet also has pallet number (1
001). Next, the machining schedule creation means 2 checks the machining parts that can be installed on the jig with this jig number (1) from among the machining parts in the scheduled machining order input by the operator, and if there are machining parts that can be installed, they are installed. That's it. Specifically, the machining schedule creation means 2 sets the jig number (1) to the first jig shown in FIG.
From the information of the memory element, the machined part numbers (5), (4), (
By knowing that the machined part 6) will be installed, and by referring to the input result by the operator's input means shown in Figure 4, it is known that the machined part number (4) will be installed, and this machined part The machined part number (4) is to be attached together with the machined part number (5), which is the first object of interest. Then, from the information in the second memory element shown in FIG. 6 provided in the machining schedule creation means 2, the machining part numbers (4) and (5) are installed, the jig number (1) is fixed, and the pallet number. (1001
), the transport time is 20 minutes and the exchange time is 10 minutes. Next, from the information in the third memory element shown in FIG. The setup time in each hour is 20
We know that the processing time is 10 minutes and 20 minutes, respectively. To summarize, the machining schedule creation means 2 determines that the machined parts with machined part numbers (4) and (5) are jig number (1).
It is known that it is attached to the jig of , and that it is attached to the pallet of pallet number (1001). Further, the machining schedule creation means 2 integrates the machining parts with machining part numbers (4) and (5), the jig with jig number (1), and the pallet with pallet number (1001) from the above-mentioned time information. , calculate working time, machining time. In this case, specifically,
The machining schedule creation means 2 first calculates the machining part number (
Adding the setup time of 4) and (5) (40 minutes, and 10 minutes of changeover time), the total work time for the worker is 50 minutes. Further, the processing schedule creation means 2
The machining time is calculated as 30 minutes by adding up the machining time of each of machining part numbers (4) and (5). Since the processing schedule creation means 2 has calculated the transportation time (α), the worker's working time (β), and the processing time (γ), the processing schedule is allocated with time as shown in FIG. I do. Note that the machined part with machined part number (4) is machined together with the machined part with machined part number (5),
Remove from the input machining schedule order. Furthermore, if there are identical machined parts in the machining order, priority is given to the one with the earliest scheduled machining order. Then, the machining schedule creation means 2 performs similar calculations focusing on the next machining component (5) to be machined, and subsequently creates the machining schedule shown in FIG. 3 in the same manner. Subsequently, the machining schedule creation means 2 stores this machining schedule in the first storage means 3. Thus, the machining schedule is stored in the first storage means 3.

Next, the comparing means 5 compares the working time period of each worker in the machining schedule shown in FIG. 8
Compare with the rest period shown in the figure. Specifically, the comparing means 5 compares the working time period and the rest time period of each worker, as shown in FIG. 9(a). Then, you can see the overlapping time periods. Then, based on the comparison result of the comparison means 5, the processing schedule adjustment means 6 focuses on the first overlapping time period and selects the The machining schedule is adjusted by shifting the worker's work time zone and subsequent machining schedule for the overlapping time period to after the break end time of the first overlapping break time zone. in particular,
The processing schedule adjustment means 6 focuses on the first overlapping time period of the plurality of overlapping time periods shown in FIG. 9(a), which is the comparison result of the comparison means 5. That is, as shown in FIG. 9(a), 1, which is the first overlapping time period,
Break time (1) from 2:00 to 13:00 and 12:40
We will focus on the time period that overlaps with the working time period of the worker of the third processing unit from 12:40 to 13:00. Note that by focusing on the first overlapping time period, by adjusting the first overlapping time period,
This is because it is conceivable that subsequent overlapping time periods will be resolved. Here, the processing unit is 1 bullet, 1 tool,
And the transportation time of the processed parts attached to them,
It refers to the time required for the entire process including work time and machining time, and the words ``first'' and ``second'' added in front of a process unit indicate the order of the process unit. Next, the worker's working time period for the focused overlap time, that is, the 20 minute period from 12:40 to 13:00 and the subsequent machining schedule are as shown in FIG. 9(b). ) after the end of the break time. In this case, the start time of the work time zone for the worker in the third processing unit was 12:40, but the start time of the break time zone (1) is set at 13:00 after the end of the break time. Then, the subsequent Kanisukeshi 1-rules are also shifted. The processing schedule is thereby adjusted. Next, this 1
The new working time period of the worker in the adjusted machining schedule (FIG. 9(b)) is compared with the break time period stored in the second storage means 4, and the new working time period and break time period of the worker are compared. If the time zones overlap, the machining schedule is adjusted again by shifting the worker's working time zone and subsequent machining schedule for the overlapping time period to after the break end time of the overlapping break time zone. That is, when the machining schedule after the first adjustment shown in FIG. 9(b) is compared with the break time period stored in the second storage means 4, it is found that the work time period and break time period of the worker of the fourth processing unit are There is a time period in which the work time period of the worker in the time period (2) and the fifth processing unit overlaps with the break time unit (3). Next, if we focus on the first overlapping time period, the 4th processing unit and the rest period (2), as mentioned above, the transportation period does not require any work by the worker, so it becomes the rest period. It doesn't matter though. Therefore, the transport time period of the fourth processing unit is also the break time period (2).
1, which is the time period in which the work time period of the worker of the fourth processing unit and the break time period (2) overlap, regardless of whether it overlaps with
The break period is from 5:10 to 3:30 p.m., and the workers' working hours and subsequent machining schedules are shifted by the overlapping time so that work starts after the break end time of this break period (2). As a result, the machining schedule adjusting means 6 adjusts the machining schedule again, as shown in FIG. 9(C). Next, the working time period of the worker in the machining schedule after the second adjustment shown in FIG. 9(C) is compared with the rest time period stored in the second recording means 4. Then, the working hours of workers in the 5th processing unit from 17:15 to 18:00 and from 17:00 to 17:03 are still
There is an overlapping time period as the rest period (3) up to 0 minutes. Therefore, the processing schedule adjusting means 6 adjusts the worker's working time period and subsequent processing schedule for the 15-minute overlap from 17:15 to 17:30 to the break end time of the break period (3). By shifting, the adjustment is made as shown in FIG. 9(d). and,
Again, the working time period and rest time period of the worker in the machining schedule after the third adjustment shown in FIG. 9(d) will be compared. Then, since there are no overlapping time slots, the adjustment by the processing schedule adjustment means 6 ends.

Next, the processing schedule was adjusted by the processing schedule adjustment means 6.

The display means 7 displays the processing schedule shown in FIG. 9(d). Specifically, the operator is notified by, for example, the display on the CRT 7 shown in FIG. 1, or by printing on a printer. In this embodiment, the processing schedule is adjusted for one day, but the processing schedule may be for example three days or one week. In addition, in this example, there were three break periods per day, but one
It may be once, or it may be several other times. Further, in this embodiment, the processing time may be arranged in the order of transport time, work time, and processing time, or may be arranged in the order of work time, transport time, and processing time. Furthermore, due to the first adjustment, a new overlap may occur in a time period that did not initially have an overlap, but the overlap can be resolved as described above.

In addition, the present invention of claim 1 compares the break time period stored in the second storage means 4 with the working time period of the worker in the machining schedule created by the machining schedule creation means 2, An invention that makes it possible to adjust the machining schedule by shifting the worker's work time zone and subsequent machining schedule for the overlapping time period after the break end time of the overlapping break time period when there are overlapping parts. It is.

Further, the present invention as claimed in claim 3 which is dependent on claim 1 provides that, when the worker's work time period and rest time period overlap in one place, after adjusting to eliminate the overlapping time period, further adjustment is made. This invention is for the case where, when an overlap occurs, the adjusted machining schedules are compared and adjusted again, and the comparison and adjustment are continued until there is no overlap.

Claim 20 The present invention is an invention in which, when a worker's work time period and rest time period overlap at a plurality of locations, adjustment is made by focusing on the first overlapping time period.

Note that the machining schedule creation means 2, the comparison means 5, and the machining schedule adjustment means 6 may be realized by software such as a microcomputer, but they can also be realized by a dedicated hardware circuit.

[Effects of the Invention] Claim 1.2.30 The present invention provides a machining schedule created by an operator and input using an input means, or a machining schedule created by using a machining schedule creation means for creating a machining schedule. Since the machining schedule adjustment means adjusts the machining schedule in consideration of the break time period, there is an effect that there is no discrepancy between the machining schedule and the actual work.
