It is judged whether or not, i.e., whether the stop state signal output from the control device 17 is input to the operation panel 2 after the sewing machine is stopped (step S9). Here, if it is determined that the sewing machine is not in the stopped state (step S9; NO), the CPU 21 proceeds to step S3 and executes the subsequent processing, so that the rotational speed information is sewing record data D at a predetermined time. ) To save.

On the other hand, if it is determined in step S9 that the sewing machine is in the stopped state (step S9; YES), that is, the thread is cut at the end of sewing and the sewing machine is in the stopped state, or once the sewing machine is stopped during sewing, the CPU 21 acquires the time when the stop state signal is input from the timer 27, and stores sewing machine stop information in the sewing record data D of the SRAM 24 in correspondence with the time (step S10). Subsequently, the CPU 21 reads the graph display control program from the ROM 22 and expands it to the RAM 23, and in accordance with the graph display control program, the graph display processing (described later in detail: step S11; see Fig. 8). ).

In the state where the operation state graph G is displayed on the display 25, the CPU 21 executes a predetermined determination program, for example, for operation by an operator such as the left or right movement switch R, L, or the like. On the basis of this, it is determined whether or not the display portion switching instruction has been input (step S12). Here, if it is determined that the display portion switching instruction has been input (step S12; YES), the CPU 21 reads the switching display control program from the ROM 22 and expands it to the RAM 23, in accordance with the switching display control program. Then, the graph switching display processing is executed (described in detail later: step S13; see Fig. 9).

If it is determined in step S12 that the display portion switching display is not input (step S12; NO), the CPU 21 proceeds to step S1 and executes the processing thereafter.

Next, the graph display processing will be described with reference to FIG.

In the graph display processing of the present embodiment described below, the operation status graph G is displayed on the basis of the start of sewing.

As shown in Fig. 8, first, the CPU 21 reads the sewing write data D from the SRAM 24 based on the execution of the graph display control program, and cuts the latest actual cutting of the sewing write data D. A process of searching for information is performed (step S21). Next, the CPU 21 performs a process of obtaining a time range that can be displayed in the display area 25a, based on the range of the horizontal axis of the display area 25a set in advance (step S22).

Based on the sewing record data D, the CPU 21 performs a process of searching for the oldest sewing start information from the time of the actual cutting with respect to the latest actual cutting information among the information corresponding to the displayable time range ( Step S23). As a result of the search, when there is sewing start regarding the sewing start information within the displayable time range (step S24; YES), the CPU 21 responds to the sewing start at the sewing start (S; for example, Fig. 4A). Control to display the operation state graph G on the display 25 so that the corresponding portion S1 at the start of sewing is aligned with the reference display position 25b (for example, the left end) of the display area 25a. (Steps S25, S27). On the other hand, when there is no sewing start regarding the sewing start information within the displayable time range (step S24; NO), the CPU 21 references the portion S corresponding to the latest sewing start as a reference to the display area 25a. Control is performed to display the operation state graph G on the display unit 25 so as to match the display position 25b (steps S26 and S27).

In this way, the indicator 25 of the operation panel 2 can be displayed with the operating state graph G on the basis of the start of sewing of the sewing machine.

Next, with reference to FIG. 9, the graph switching display process is demonstrated.

In the graph switching display processing of the present embodiment described below, the operation status graph G is switched and displayed on the basis of sewing start.

As shown in Fig. 9, first, the CPU 21 determines whether or not the pressurized operation time of the operated left or right movement switch R, L is longer than a predetermined time, based on the execution of the graph change display control program. (Step S31).

Here, when it is determined that the pressurization operation time is longer than the predetermined time ("long press") (step S31; YES), the CPU 21 determines whether the operated switch is the left shift switch L or the right shift switch ( A process of determining whether or not it is R) is performed (step S32).

If it is determined in step S32 that the left shift switch L is pressed for a long time, the CPU 21 based on the sewing recording data D, the reference display position 25b of the display 25 in the operation status graph G. ), The process of searching for sewing start information corresponding to the start of sewing start thereafter (step S33) is performed, and the portion S corresponding to the retrieved sewing start information is set as the reference display position ( The display position is switched to fit 25b) to display the operation status graph G (step S35).

On the other hand, when it is determined in step S32 that the right shift switch R is pressed for a long time, the CPU 21 based on the sewing record data D, the reference display position 25b of the display 25 in the operation status graph G. Is closest to the portion corresponding to the above), and processing for searching for sewing start information corresponding to the previous sewing start is performed (step S34), whereby the portion S corresponding to the retrieved sewing start information is selected as the reference display position ( The display position is switched to fit 25b) to display the operation status graph G (step S35).

In this way, on the display 25 of the operation panel 2, on the basis of the start of sewing of the sewing machine, the graph display portion displayed in the display area 25a of the display 25 of the operation status graph G is displayed. The operation status graph G may be displayed by switching along the time axis.

In addition, when it is determined in step S31 that the pressurization operation time is shorter than the predetermined time (step S31; NO), the CPU 21 determines whether the operated switch is the left shift switch L or the right shift switch R. A process of determining whether or not is performed (step S36).

Here, when it is determined that the left shift switch L has been operated, the CPU 21 performs a process of moving and displaying the operation status graph G to the left by one dot of the display 25 (step S37), and then moving to the right. If it is determined that the switch R has been operated, a process of moving and displaying the operation status graph G to the right by one dot of the display 25 is performed (step S38).

In this manner, the display position of the operation state graph G displayed on the display 25 can be finely adjusted in units of 1 dot.

As described above, according to the sewing recording apparatus 100 of the sewing machine of the present embodiment, the graph display processing is executed in the sewing machine stopped state, and at the start of sewing in the operation status graph G with reference to the sewing start time.

That is, the operation state graph so that the display position of the operation state graph G is aligned with the portion S corresponding to the start of sewing to the reference display position 25b of the display 25 without performing a predetermined alignment operation or the like. (G) can be displayed appropriately, and therefore, the operating state of the sewing machine can be grasped easily and appropriately based on the operation state graph (G).

In the graph display switching processing, whenever the display portion switching instruction outputted by the operation of the left and right movement switches L and R is input to the CPU 21, the operation status graph G is performed on the basis of the start of sewing. ), The graph display portion displayed in the display area 25a can be switched along the time axis, so that the operating state of the sewing machine can be grasped more appropriately.

In addition, when the CPU 21 of the operation panel 2 displays the operation status graph G in the graph display processing and the graph display switching processing, the operation status graph G together with the operation status graph G is displayed. The operating rate (W) and the average rotational speed (A) of the sewing machine in the thread cutting section from the first thread cutting time to the latest thread cutting time in the range indicated in the display area 25a of the indicator 25 are displayed. can do.

That is, the CPU 21 reads the operation rate calculation program from the ROM 22 and expands it to the RAM 23, and calculates the operation rate W of the sewing machine in the thread cutting section based on the execution of the operation rate calculation program. Run the process. Further, the CPU 21 reads out the average rotational speed calculation program from the ROM 22 and expands it to the RAM 23, and based on the execution of the average rotational speed calculation program, the average rotational speed of the main axis in the actual cutting section. The process of calculating (A) is executed. The CPU 21 controls the display 25 to perform a process of displaying the operation rate W and the average rotational speed A of the sewing machine together with the operation status graph G. FIG.

Accordingly, for example, when the average rotational speed A is low even if the sewing machine operation rate W is high, the worker's work efficiency can be judged to be poor, so that the manager can more easily grasp the sewing work situation. In this way, the operating status of the sewing machine can be more easily analyzed.

In addition, the range in which the operation rate W and the average rotational speed A of the sewing machine are calculated is not limited to the thread cutting section from the earliest thread cutting to the latest thread cutting. For example, it may be changed by appropriately setting any one of sewing start, sewing machine stop, sewing machine start and thread cutting.

Since only the section data relating to the section of D can be extracted and obtained, and the obtained section data can be recorded on the recording medium M, only the information of the desired section is extracted from the sewing record data D, and is different from the SRAM 24. It can record on the recording medium M as a means, and the recording capacity of the recording medium M can be saved.

In addition, when the section data recorded on the recording medium M is read out and displayed on the display unit 25, the operation state graph G according to the desired section can be displayed, so that another operation state graph G is displayed. It can be conveniently used for comparison and contrast, and it is easy to grasp the operation status of the sewing machine or analyze the work efficiency.

In addition, since the recording medium M is detachably attached to the operation panel 2, the display section 25 reads predetermined section data recorded on the recording medium M with a sewing recording device of another sewing machine or the like. The operation state graph G regarding the section data can be displayed on the screen, so that the operation state of the sewing machine and the analysis of the work efficiency can be easily performed.

In addition, the recording medium M may be such that, for example, the operation panel 2 and the recording medium M are connected by a wired or wireless communication line to transmit and receive data by a predetermined communication method. That is, section information transmission means for transmitting desired section data of the sewing recording data D is provided on the operation panel 2, and section information reception for receiving section data transmitted from the section information transmission means on the recording medium M is performed. A means may be provided.

Accordingly, the section data can be easily transmitted and received between the operation panel 2 and the recording medium M, and the handleability of the section data can be further improved.

In the above embodiment, the section data is acquired so that a predetermined range is selected and set based on the operation of the predetermined operation switch 26 on the operation status graph G displayed on the indicator 25 of the operation panel 2. It is made, but it is not limited to this. For example, during the sewing operation of the sewing machine, the sewing start time detected by the CPU 21 immediately after the recording start switch (not shown) is operated at a predetermined timing, and the like as the start point of the interval data. Section data whose end point is the point of time determined as the latest actual cutting time at the time of operation) may be taken out.

Further, in the above embodiment, the section data is to be recorded on the recording medium M, which is a recording means different from the SRAM 24, but the present invention is not limited thereto. For example, sewing recording data D is recorded in the SRAM 24. A predetermined recording area different from the area to be provided may be provided so that the section data can be recorded in the recording area.

Further, in the above embodiment, the setting means (e.g., the setting time point) that can set any one of the start points of the sewing machine, the sewing machine stop, and the sewing machine start during the operation of the sewing machine on the basis of the operation as a reference time in the graph display process (for example , Operation switch 26, etc.) may be provided.
