At this time, specifying may be a combination of a plurality of continuous sewing data or a combination of one or a plurality of continuous sewing data and one or a plurality of individual sewing data.

The control means starts sewing according to the continuous sewing data or the individual individual sewing data in the specified order while referring to the storage means. The sewing needle and the cloth are moved by the moving means so that the sewing is performed at each needle drop position specified in the individual individual sewing data or in the case of continuous sewing data, or at the needle drop position specified in the sewing data included therein. Relatively positioning and at the same time the lowering operation of the sewing needle is performed by the drive means.

In the case where the object of sewing is continuous sewing data, sewing by a plurality of sewing data contained therein is performed while the cloth pressing means continues the pressing state in order.

In the above configuration, whenever the sewing is performed on the individual sewing data or the continuous sewing data, it is necessary to press the cloth again by the cloth pressing means. Therefore, the control means stops sewing operation once each sewing data or continuous sewing data is sewn, waits for the pressing of the cloth pressing means again, and then sewing based on the next single sewing data or continuous sewing data is performed. Is done.

Further, the pressing by the cloth pressing means may input the completion of the pressing again after the user of the sewing machine performs the pressing operation again.

The control unit 100 processes various programs stored in the ROM 102 through the RAM 103, and the CPU 101 processes the continuous sewing data and the single sewing data related to the sewing pattern (sewing data included in the continuous sewing data). In order to be distinguished from the above, sewing data for which sewing is individually performed is referred to as single sewing data), and sewing control is executed based on each of these setting data.

Here, the setting input method of the continuous sewing data by the control means 100 will be described.

In the present invention, it is assumed that various sewing data are registered as initial values in advance in the RAM 103 or the nonvolatile memory.

(Creation processing of continuous sewing data)

The control means 100 having the above configuration performs the following various processes in accordance with various programs. Each process is explained in order.

Here, a case where setting and inputting continuous sewing data in combination with sewing patterns No. 1 and No. 2 is illustrated.

First, the CPU 101 displays the continuous sewing data setting screen G1 (FIG. 6) on the operation panel 20 based on the image data recorded in the ROM 102. The display M1 in the continuous sewing data setting screen G1 indicates the continuous sewing pattern No. The sewing data candidate display button B1 is displayed below the display M1. Upon detecting the input of the sewing data candidate display button B1, the CPU 101 performs a process of converting the display to the sewing data candidate selection screen G2 (Fig. 7).

In the sewing data candidate selection screen G2, a plurality of registered sewing data selection buttons B2 serving as candidates are displayed at the bottom thereof. Next to it, a scroll button B3 for displaying an undisplayed sewing data selection button B2 is displayed. When the input of one of the sewing data selection buttons B2 is detected, a process of converting the button B2 to the inverted black and white display is performed. In this state, the selection is still indeterminate tentative selection, and at the top, various set values of the sewing data selected tentatively in the lower stage and the definite selection button B4 of the tentative selection are displayed.

On the sewing data candidate selection screen G2, when sewing data selection button B2 of sewing pattern No. 1 is input and input of the confirmation button B4 is detected, the CPU 101 again displays on the continuous sewing data setting screen G1 (Fig. 8). The process of converting is performed. In this step, the sewing pattern No. is displayed on the sewing data candidate display button B1 described above on the continuous sewing data setting screen G1. Next to the sewing data candidate display button B1, the simple parameter display M2 of sewing pattern No. 1 is displayed.

Then, below the sewing data candidate display button B1 and the simple parameter display M2, a display of the feed amount setting button B5 along the front and rear directions to the sewing pattern to be sewn next is performed.

Upon detecting the input of the feed amount setting button B5, the CPU 101 performs the display processing of the numerical input subscreen G3 (Fig. 9). In the numerical input sub-screen G3, the numerical increase / decrease button B6 for changing the numerical value of the conveyed amount and the numerical confirmation button B7 for confirming the conveyed amount value are displayed.

When the feed amount value is set and input in the numerical input sub-screen G3 and the input of the confirmation button B7 is detected, the CPU 101 erases the display of the numerical input sub-screen G3, and the continuous sewing data setting screen G1 (Fig. 10). A process of displaying is performed. In this step, the feed amount set in the above-mentioned feed amount setting button B5 of the continuous sewing data setting screen G1 is displayed. The sewing data candidate display button B1 of the sewing pattern for which sewing is performed for the second time is displayed below the feed amount setting button B5. When the input of the sewing data candidate display button B1 is detected, the CPU 101 performs a process of converting the display to the sewing data candidate selection screen G2 (Fig. 11) as in the previous time.

The sewing data candidate selection screen G2 displays a plurality of registered sewing data selection buttons B2 that are candidates at the bottom. When the sewing data selection button B2 of sewing pattern No. 2 is input and the input of the confirmation button B4 is detected again, the CPU 101 again performs a process of converting the display to the continuous sewing data setting screen G1 (Fig. 12). In this step, the sewing pattern No. is displayed on the second sewing data candidate display button B1 of the continuous sewing data setting screen G1, and the simple parameter display M2 of the sewing pattern No. 2 is displayed next to the sewing data candidate display button B1. Display is performed.

Each time the sewing data of the sewing pattern is newly selected, the CPU 101 updates and registers the continuous sewing data in the RAM 103 or the nonvolatile memory.

Therefore, the continuous sewing data which consists of sewing patterns No. 1 and No. 2 is formed by the said process. Such continuous sewing data is registered as continuous sewing pattern No. 1.

In addition, when applying a sewing pattern again, the process of FIGS. 9-12 may be repeated.

(Setting input data reception conversion processing)

Here, the processing for converting which setting input from among combination data, continuous sewing data, and single sewing data which combines a plurality of continuous sewing patterns or a single sewing pattern is received will be described.

In the case of performing such various data settings, in any one screen display state, the data for setting input can be selected by inputting the mode conversion switch W1 in the fixed switch described above.

Upon detecting the input of the mode conversion switch W1, the CPU 101 performs a process of converting the display to the setting data selection screen G4 (Fig. 13). In the setting data selection screen G4, the setting data selection button B8 is displayed. The setting data selection button B8 itself displays three types of data (single sewing data, combination data, and continuous sewing data) that receive setting inputs, respectively, at the upper and lower ends, and at the same time, the coloring of the data stages that can be accepted. Is done.

That is, in Fig. 13, a state in which the setting input of the continuous sewing data at the lower end is possible is selected, and the coloring display position and the inputtable data are switched each time an input operation is performed on the setting data selection button B8. FIG. 14 shows a state in which two input operations are performed from the state of FIG. 13, and setting input of the combination data is enabled.

When data for which setting input is to be performed is selected in this way, the mode conversion switch W1 is input again to convert to the setting input screen of each data.

(Combination data creation processing such as continuous sewing data and single sewing data)

Here, the case of setting and inputting the combination data which consists of combining three continuous sewing patterns No. 1 is shown.

When the selection and confirmation of the combination data is detected by the above-described setting input data reception conversion process, the CPU 101 sets the combination data setting screen G5 on the operation panel 20 based on the image data recorded in the ROM 102 (Fig. 15). ).

At the top of the combination data setting screen G5, the combination pattern conversion button B9 showing the current combination as the pattern number and the sewing position display M3 performed by each data included in this combination data are displayed. In this sewing position display M3, a button cursor is displayed during the current setting input, and a process of converting the display to a rounded numbered icon in the sewing order is performed (see Fig. 18).

When the input of the combination pattern conversion button B9 is detected, the CPU 101 displays a selection screen (not shown) of another combination pattern and receives a selection.

At the bottom of the screen, the sewing data selection button B10 is displayed at the center thereof, and the cursor display position change button B11 is displayed in each of the up, down, left and right directions centering on the button B10. This cursor display position change button B11 is used only for changing the display position of the button cursor in the sewing position display M3, and does not participate in the actual sewing position.

Upon detecting the input of the sewing data selection button B10, the CPU 101 performs a process of converting the display to the single sewing data candidate selection screen G6 (Fig. 16).

In this single sewing data candidate selection screen G6, a plurality of registered sewing data selection buttons B12 serving as candidates are displayed at the bottom thereof. Next to it, a scroll button B13 for displaying another sewing data selection button B12, which is not displayed, is displayed. When the input of the sewing data selection button B12 is detected, the provision of the black and white inverted display is made to the button B12, and various set values of the selected sewing data and the confirmation button B14 of the temporary selection are displayed at the top. When the input of the confirmation button B14 is detected, the single sewing data selected in the combination data is assembled.

The sewing data type conversion button B15 is displayed at the top of the single sewing data candidate selection screen G6. Upon detecting the input of button B15, the CPU 101 performs a process of converting the display to the continuous sewing data candidate selection screen G7 (Fig. 17).

In the continuous sewing data candidate selection screen G7, a plurality of registered continuous sewing data selection buttons B16 serving as candidates are displayed at the bottom thereof. Next to it, a scroll button B17 for displaying another non-displayed continuous sewing data selection button B16 is displayed. When the input of the continuous sewing data selection button B16 is detected, the B black display display is temporarily selected for this button B16, and at the top, the set value of the various kinds of sewing data at the head of the selected continuous sewing data and the definite selection button B18. Is displayed. When the input of the confirmation button B18 is detected, the continuous sewing data selected in the combination data is assembled.

According to the above-described example, upon detecting the selection of the continuous sewing pattern No. 1 and the confirmation input on the continuous sewing data candidate selection screen G7, the CPU 101 performs a process of converting the display to the combination data setting screen G5 (Fig. 18) again. Do it. In the sewing position display M3 of the combination data setting screen G5, since the continuous sewing data of the first continuous sewing pattern No. 1 is assembled in advance, the rounded number one showing the first data registration of the combination at the original button cursor position is shown. The icon is displayed. And a button cursor is displayed below it.

In the case of registering the second and third continuous sewing patterns No. 1 according to an example, the same operation as the registration of the first continuous sewing pattern No. 1, namely (1) input of sewing data selection button B10, (2 In the single sewing data candidate selection screen G6, input of sewing data type conversion button 15 and (3) continuous sewing data candidate selection screen G7 are repeated twice.                     

When the second and third consecutive sewing patterns No. 1 are registered, the continuous sewing data of three continuous sewing patterns No. 1 is assembled in the sewing position display M3 of the combination data setting screen G5 (Fig. 19). As indicated by three data registrations, three icons of round numbers 1, 2, and 3 are displayed side by side.

Although a button cursor is displayed below it, in this combination data creation process, it is updated by overwriting (overwriting) each time new continuous sewing data or single sewing data is applied, and thus it is not necessary to finally enter a confirmation. In other words, the registration data of the combination of three continuous sewing patterns No. 1 as the combination pattern No. 1 is already completed at this stage.

(Description of operation of buttonhole sewing machine)

20 is a flowchart showing the sewing operation processing of the buttonhole sewing machine 10 executed by the CPU 101 of the control means 100 in accordance with a program stored in the ROM 102. FIG. 21 shows the sewing screen G8 converted from the combination data setting screen G5 (see FIG. 19) in which the combination pattern No. 1 is selected by the input of the sewing start switch W2 in the fixed switch of the operation panel 20. FIG.

Upon detecting the input of the sewing start switch W2, the CPU 101 sets a count value n for counting the number of sewing data (the continuous sewing data or the individual sewing data is counted as one) registered in the combination data to 1 ( Step S1).

As described above, the CPU 101 displays the sewing screen G8 (Fig. 21). At the top of the sewing screen G8, the current sewing data display M4 is displayed. In the current sewing data display M4, a plurality of rounded number icons are displayed side by side according to the number of sewing data registered in the combination data. In combination pattern No. 1, since three consecutive sewing data are registered, round number icons are displayed from 1 to 3. In addition, each round-numbered icon displays richer colors than other icons for the icon of the sewing data currently being sewn.

In the lower part of the sewing screen G8, when the sewing data currently being sewn is the single sewing data, detailed setting values of this sewing data are displayed. When the sewing data currently being sewn is continuous sewing data, detailed setting values of the sewing data for which the current sewing is performed are also displayed in the continuous sewing data.

The CPU 101 then refers to the combination data for sewing and recognizes the number of sewing data registered therein. Specifically, in the combination pattern No. 1, since three pieces of continuous sewing data of the continuous sewing pattern No. 1 are registered, the number of sewing data for discriminating and recognizing this is automatically set. Then, the number of recognition sewing data 3 and the above-described count value n are compared and judged, and when the number exceeds 3 (n> 3), the sewing end processing is performed (step S2: YES).

In step S2, in this step, it is before the start of continuous sewing or single sewing, and since n = 1 (step S2: NO), the set waits for the cloth to the sewing position (step S3). In this step, the user of the sewing machine arranges the sewing start position of the cloth to be the lower side of the sewing needle 11 and at the same time instructs the lowering operation of the cloth pressing frame 42 by the input pedal 44b to raise the pressing portion of the CPU. The detection means added to the 101 detects this, and the CPU 101 performs operation control for starting the drive of the sewing machine motor 32.

By driving the sewing machine motor 32, the CPU 101 refers to sewing data registered at the nth of the combination data according to the current count value n and performs sewing along this data (step S4). Specifically, when sewing is performed according to the continuous sewing data of the continuous sewing pattern No. 1, sewing is performed according to the sewing data of the sewing pattern No. 1 included therein. In addition, according to the button hole to be formed, the female drive solenoid 74 is driven one to many times, and the button hole is formed on the cloth.

At this time, the present continuous sewing pattern No. and the sewing pattern No. currently sewn in this way are included. And a sewing screen G8 (Fig. 21) displaying the contents thereof.

In addition, when sewing of sewing pattern No. 1 included in the continuous sewing pattern No. 1 is finished, the sewing machine motor 32 is stopped and driven by the transfer motor 53 according to the set feed amount up to the next sewing pattern No. 2. The cloth is pressed by the cloth pressing frame 42 (step S5).

When the cloth is sent, the driving of the sewing machine motor 32 is resumed, and the CPU 101 performs sewing according to the sewing data of the sewing pattern No. 2 included in the continuous sewing data of the continuous sewing pattern No. 1 having the current count value 1. It performs (step S6).

At this time, the present continuous sewing pattern No. 1 and also the sewing pattern No. currently contained therein are sewn. 2 and a sewing screen G8 (Fig. 22) displaying the contents are displayed.

When sewing of sewing pattern No. 2 included in the continuous sewing pattern No. 1 is finished, the sewing machine motor 32 is stopped and the cloth pressing frame 42 is moved upward by driving the lifting solenoid 44 (step S7). . Thereby, sewing of the 1st continuous sewing pattern No. 1 is completed. The CPU 101 then adds 1 to the count value n (step S8).

As described above, the CPU 101 displays the sewing screen G8 (Fig. 23). In the round number icon of the current sewing data display M4 displayed on the top of the sewing screen G8, the second round number icon corresponding to the count value n is displayed in thick color.

At the lower end, sewing from this means that the sewing pattern No. 1 of the continuous sewing pattern No. 1 of the continuous sewing data is displayed and the various set values are displayed.

The CPU 101 returns the processing to step S2 and compares the count value n with the number of sewing data of the combination pattern No. 1.

If the count value does not exceed 3, which is the prescribed value, the new positioning and pressing of the input pedal for pressing the cloth for sewing in accordance with the continuous sewing data of the continuous sewing pattern No. 1, the second sewing data registered in the combination data. Input standby (step S3).

In the same manner as described above, the processes to steps S4 to S8 are performed, and the processes to steps S2 to S8 are repeated again in the same manner. Then, count value n = 4, and sewing is finished by the process of step S2.

In addition, in the above embodiment, the example of repeating the continuous sewing pattern for sewing two sewing patterns consecutively three times is shown that the pressing shape (shape or size of the cloth pressing frame 42) can continuously sew the two sewing patterns. Because it is formed to be.

For example, when the pressing shape can sew three sewing patterns continuously, three sewing patterns can be set in the continuous sewing pattern. In this case, the continuous sewing data in which three sewing data are registered in the same manner as described above is registered as the continuous sewing pattern No. 3, and at the time of sewing, the continuous sewing pattern No. 3 is detected and the sewing pattern of S4 in FIG. It is also possible to automatically set the CPU 102 to execute the processing as repeating means for repeating the formation and repeating the transfer process of S5 three times.

In this way, the number of sewing patterns for continuous sewing is 4, 5, 6. Can be arbitrarily increased.

When the continuous sewing and the single sewing are mixed, the number of repetitions by the processing of the CPU 102 as the repetition means is detected, and in the case of the continuous sewing, the number of sewing patterns is detected and the number of sewing patterns of 2-3 or more is determined. It is possible to sew by setting the number of repetitive patterns to 1 and sewing alone.

The invention described in Claims 1 and 2 is inputted and stored in advance for a combination of a plurality of continuous sewing data or a combination of a continuous sewing data and a single sewing data, and is pressed again by a cloth pressing means for each continuous sewing data or individual sewing data. By detecting, it is possible to shift to sewing by the next sewing data. Therefore, every time the fabric is pressed again by the cloth pressing means, there is no need for setting input or next operation instruction input as in the prior art. Sewing can be performed.

In addition, the sewing process can be executed as a series of processes by a large number of continuous sewing data that has not been performed in the past, so that the sewing work can be made more efficient and faster.

Even if there are many sewing processes based on continuous sewing data or single sewing data to be performed on another cloth, these can be collectively set and inputted as a series of sewing data groups so that setting input frequency can be reduced and sequential work can be performed. Because of this, it is possible to speed up work and increase efficiency.

The invention of claim 3 includes a display means, and the display means specifies and displays the continuous sewing data currently being sewn and the sewing data or single sewing data contained therein. It is possible to recognize. Moreover, since the sewing data which was sewn up until just before pressing can be recognized again, the pressing position with respect to the cloth can be prevented from being mistaken even when pressing again by the cloth pressing means.

(Effect of Example)

The buttonhole cutting sewing machine 10 inputs a combination of a plurality of continuous sewing data or a combination of continuous sewing data and individual sewing data and stores it in the RAM 103 or the like by input setting processing of the operation control 100 in advance. In order to shift the set position of the cloth to the sewing machine for each continuous sewing data or individual sewing data, the operation of the pedal 44b for pressing the pressing portion again by the cloth pressing frame 42 of the cloth pressing means 40 is detected. In this case, it is possible to shift to the sewing process by the next sewing data. Therefore, each time the cloth is pressed again by the cloth pressing means, it is not necessary to perform the setting input or the next operation instruction input. Can be done.

In addition, a combination of a plurality of continuous sewing data or single sewing data, which has not been conventionally performed, can be performed as a series of sewing processes that have been divided into a plurality of times, and the sewing work can be made highly efficient and speedy.

In addition, even when there are many sewing processes based on continuous sewing data or single sewing data to be performed on one cloth, the input setting processing by the CPU 102 can be set and inputted together as a series of sewing data groups at once. In addition, since it can be registered in the RAM 103 or the like, the setting input frequency can be reduced, the work can be continued, and the work can be made faster and more efficient.

In addition, the CPU 101 can identify, on the display unit 22 of the operation panel 20, whether the continuous sewing data currently being sewn, sewing data contained therein, or registered data of a single sewing data, in accordance with the processing of the program. In order to display and specify various setting values for each sewing data, the operator of the sewing machine can immediately recognize the current sewing pattern and its contents. In addition, since the type and content of the sewing data to be executed from now on are displayed immediately before the pressing operation again, even when the pressing by the cloth pressing frame 42 of the cloth pressing means 40 is performed again, the sewing data is changed from this to the fabric by misrecognition. The accuracy of the work can be maintained by avoiding the mistake of the push position.

In addition, in this embodiment, the buttonhole sewing machine is exemplified, but the present invention may be applied to other sewing machines in which sewing data is created in units of one sewing pattern, and sewing is performed for each sewing data. For example, you may apply this invention to the shape sewing machine which forms sewing patterns for every various shape, and performs sewing in the unit.

In the above embodiment, only the case where only a plurality of continuous sewing data is made as the combination data is illustrated, but the continuous sewing data and the individual sewing data may be combined.

As the lifting operation means, other actuators such as a pulse motor and an air cylinder may be used instead of the solenoid.
