The drive mechanism 30 has: an upper shaft 31 rotatably supported inside the sewing machine head 2a in a state along the front-rear direction; a sewing machine motor 32 connected to one end of the upper shaft 31; The crank mechanism 33, and the needle bar 34 at the front end of the sewing machine head 2a and through which the crank mechanism 33 transmits the vertical driving force.

The needle bar 34 holds the needle 11 at its lower end, and the needle bar 34 is supported on the upper portion of the sewing machine head 2a by the moving mechanism 50 so that it can swing flexibly around the front-back direction.

Further, the driving mechanism 30 is configured to drive the vertical movement of the needle 11 at the same frequency as the output rotation speed of the sewing machine motor 32 .

The cloth pressing mechanism 40, as shown in FIG. 2 , has: a cloth holding plate 41 that can move forward and backward and is placed on the sewing machine bottom plate 2b; a presser foot frame 42 that clamps the cloth from above the cloth holding plate 41; The frame supporting body 43 arranged on the presser foot frame 42, the presser foot lifting solenoid 44 (lifting action mechanism, refer to Fig. 5).

The above-mentioned presser foot frame 42 is a rectangular frame, and the inner side of the presser foot frame 42 penetrates up and down, and buttonhole sewing can be performed in the inner area of the frame. That is, the needle 11 is arranged inside the presser frame 42 and moves up and down. Similarly, a later-described cutter 71 of the cutter mechanism 70 is also arranged inside the presser frame 42 so that it can move up and down. In addition, the presser frame 42 of various lengths in the front-rear direction can be exchanged. The presser frame 42 in this embodiment has an elongated shape in the front-back direction capable of forming a plurality of buttonhole stitches in the front-back direction.

In addition, since the cloth is clamped by the presser foot frame 42 and the cloth holding plate 41 , a through hole through which the needle 11 and the cutter 71 pass downward is formed in the cloth holding plate 41 .

Also, the presser frame 42 is supported by a support arm 51 of a moving mechanism 50 described later so as to be able to move up and down, and a presser lift solenoid 44 imparts a lift motion to the presser frame 42 in the supported state.

Therefore, the cloth pressing frame 42 on the front end side can be raised and lowered relative to the cloth holding plate 41, and the holding of the cloth can be switched. and lifted.

In addition, the presser foot frame 42 and the cloth holding plate 41 can be moved and positioned in the front-rear direction by the same movement amount by the above-mentioned support arm 51 and the support body 52 . In addition, the needle bar support body 55 supporting the needle bar 34 swings around the front-rear direction, and moves and positions the front end of the needle 11 in the left-right direction. Therefore, the needle 11 can drop the needle at any position on the plane of the cloth held by the cloth press frame 42 and the cloth holding plate 41 .

The rotary hook mechanism 60 has: a vertical shaft 61 arranged in the vertical body part 2c and transmitting torque from the upper shaft 31 through a bevel gear; The lower shaft 62 and the rotary hook 63 driven to rotate at the front end of the lower shaft 62 . The rotary hook 63 is driven to rotate synchronously with the vertical motion cycle of the machine needle 11, and utilizes the cooperative action of the machine needle 11 and the rotary hook 63 to form stitches on the cloth. In addition, since the rotary hook 63 is the same as a conventionally well-known structure, its structure will not be described in detail.

FIG. 3 is an exploded perspective view of the cutter mechanism 70 . As shown in this FIG. 3 , the cutter mechanism 70 has: a cutter 71 for forming a buttonhole on the cloth, a cutter 71 held by its lower end and supported on the front end of the sewing machine head 2a in a vertically movable manner. Holder 72 , extension spring 73 that applies constant tension upward to cutter holder 72 , and cutter drive solenoid 74 that moves cutter holder 72 downward against the tension of extension spring 73 by its drive energy.

In this knife mechanism 70, the knife driving solenoid 74 drives the knife holder 72 downward under the control of the operation control mechanism 80 described later, and lowers the knife 71 to the inner area of the presser frame 42, and the The cutter 71 pierces the held cloth to form a buttonhole. Moreover, since the presser frame 42 can be moved and positioned in the front-back direction by the moving mechanism 50, the buttonhole formation position can be positioned in the front-back direction.

The buttonhole sewing machine 10 has an operation panel 20 as an input means shown in FIG. 4 for an operator to perform various settings and operations necessary for sewing. FIG. 4 is an external front view of the operation panel 20 . The operation panel 20 and the sewing machine body are connected by a wired or wireless line not shown. As shown in FIG. 4 , the operation panel 20 has a display unit 22 as display means for displaying various settings and operation states of the sewing machine. The display unit 22 is a so-called touch panel switch, and various setting inputs described later can be performed using displayed buttons. Also, below the display unit 22 of the operation panel 20, fixed switches 21 for inputting various settings and operations are provided, and each fixed switch 21 has a certain function irrespective of display switching.

The main parameters set by the operation panel 20 include the width of the cutter (the cutter 71 can be replaced and input the width of the currently installed cutter 71), the size of the presser foot frame 42 (the presser foot frame 42 can be replaced by the front and rear direction different sizes and input the width of the currently installed presser foot frame 42), various settings of continuous sewing data composed of a plurality of sewing data that determine various sewing patterns are performed, and are performed according to various sewing data. The interval of each sewing pattern, the sewing machine speed (the number of revolutions of the sewing machine motor 32 ), etc. during sewing.

In this case, the sewing pattern refers to a pattern for buttonhole-locking one buttonhole.

More specifically, regarding the sewing data, it is possible to specify the width of the buttonhole in the front-back direction, the length of the backtack in the front-back direction, the sewing pitch, the stitch width in the left-right direction, the pitch of the backing seam, and the buttonhole and its left and right side lines respectively. The gap width of the trace of the trace. These parameters are individually set by the user of the sewing machine, and can be recorded in RAM 103 or a nonvolatile memory described later as individual sewing data including sewing patterns formed by inputting the settings. In addition, the individual sewing data configured by setting each of the above-mentioned parameters in advance may be stored in RAM 103 or a nonvolatile memory from the outside.

In addition, various sewing data are assigned a sewing pattern No. at the time of registration, and are stored together with the sewing pattern No. In addition, the sewing pattern No. can be used for reading.

In addition, the continuous sewing data includes a plurality of data when sewing with a plurality of sewing patterns is performed within the range that can be sewn in the state where the presser foot frame 42 is lowered (without changing the presser position) The combined configuration of sewing data also includes data on the sewing order and sewing interval (cloth feed amount) using each sewing data. These parameters are individually set by the user of the sewing machine, selected from sewing data groups stored in RAM 103 or non-volatile memory, combined, and re-registered as one continuous sewing data. In addition, the continuous sewing data formed by setting each parameter of the continuous sewing data in advance may be registered in RAM 103 or a nonvolatile memory in advance from the outside.

In addition, the so-called sewing data is data for forming an individual sewing pattern, and the "individual sewing data" is independent sewing data, and is also included in the sewing data when it is combined with the combination data described later. It is necessary to correct the sewing data of the presser cloth of the presser foot frame 42 before and after its sewing during sewing. That is, the sewing data included in the continuous sewing data and the structure of the data are not changed, but are defined for convenience of description.

In addition, various sewing data are assigned a sewing pattern No. at the time of registration, and are stored together with the sewing pattern No. In addition, the sewing pattern No. can be used for reading.

Moreover, the buttonhole sewing machine 10 is characterized in that a plurality of continuous sewing data or continuous sewing data are combined with individual sewing data, and each continuous sewing data or continuous sewing data and sewing data , Sewing is carried out by continuously clamping the cloth pressing mechanism 40 for correcting the cloth pressing operation (the work of changing and adjusting the cloth pressing position).

FIG. 5 is a control system of the buttonhole sewing machine 10 . As shown in FIG. 5 , the buttonhole sewing machine 10 is connected to the sewing machine motor 32 , the swing motor 57 , the cloth feed motor 53 , the cutter drive solenoid 74 , the presser foot lift input pedal 44 b , and the operation panel 20 . The control mechanism 100. The control mechanism 100 controls the rotation speed of the sewing machine motor 32, the driving timing and swing width of the swing needle motor 57, the cloth feeding amount by the cloth feeding motor 53, the lifting and lowering switching of the presser foot frame 42, the lowering timing of the cutter 71, etc. . The motion control mechanism 100 has a CPU 101 , a ROM 102 , a RAM 103 , and an I/O interface 104 . A ROM 102, a RAM 103, and an I/O interface 104 are connected to the CPU 101 via bus lines.

The sewing machine motor 32 is connected to the I/O interface 104 via the sewing machine motor driver 32a. An encoder 32b for detecting the number of revolutions of the sewing machine motor 32 is connected to the sewing machine motor driver 32a, and feedback control can be performed.

Further, a needle up position sensor 32c for detecting the rise of the needle 11 is connected to the sewing machine motor driver 32a. In this way, the number of stitches when the needles 11 form stitches can be counted by the control unit 100 .

In addition, a cloth feed motor 53 is connected to the I/O interface 104 via a cloth feed motor driver 53a. In addition, the cutter drive solenoid 74 is connected to the I/O interface 104 via the cutter drive circuit 74a.

Furthermore, the lift solenoid 44 is connected to the I/O interface 104 via the presser lift drive circuit 44 a, and the presser lift input pedal 44 b is connected to the I/O interface 104 .

For the control unit 100, the CPU 101 uses the RAM 103 to process various programs stored in the ROM 102 to receive continuous sewing data and individual sewing data related to the sewing pattern (in order to distinguish it from the continuous sewing data included in the continuous sewing data). The sewing data for performing individual sewing is referred to as individual sewing data) and the setting input is performed and sewing control is performed based on the setting data.

Here, a method of setting continuous sewing data by the motion control mechanism 100 will be described.

In addition, in this description, various sewing data are registered in RAM103 or a nonvolatile memory as an existing initial value.

(Continuous sewing data creation process)

The motion controller mechanism 100 configured as described above performs the following processes according to various programs. Each process will be described in order.

At this time, the case of setting and inputting continuous sewing data of a combination of sewing patterns No. 1 and No. 2 is taken as an example.

First, CPU101 displays continuous sewing data setting screen G1 (FIG. 6) on operation panel 20 based on the image data stored in ROM102. And, the display M1 on the continuous sewing data setting screen G1 shows the continuous sewing pattern No. A sewing data candidate display button B1 is shown below the display M1. When the input of the sewing data candidate display button B1 is detected, the CPU 101 performs a process of switching the display to the sewing data candidate selection screen G2 ( FIG. 7 ).

On the sewing data candidate selection screen G2, a plurality of sewing data selection buttons B2 registered as candidates are displayed on the lower stage. Moreover, the screen scroll button B3 which can display the other sewing data selection button B2 which is not displayed is displayed beside it. When the input of any one of the above-mentioned sewing data selection buttons B2 is detected, the button B2 is displayed in reverse black and white. In this state, the selection is a provisional selection state that has not yet been determined, and in the upper stage, various setting values of the sewing data temporarily selected in the lower stage and a confirmation button B4 for provisional selection are displayed.

On the sewing data candidate selection screen G2 mentioned above, when the sewing data selection button B2 of sewing pattern No. 1 is input and the input of the OK button B4 is detected, the CPU 101 switches the display to the continuous sewing data setting again. Processing of screen G1 (Fig. 8). At this stage, the sewing pattern No. is displayed on the above-mentioned sewing data candidate display button B1 on the continuous sewing data setting screen G1. In addition, beside the sewing data candidate display button B1, the simple parameter display M2 of the sewing pattern No. 1 is displayed.

Then, below the sewing data candidate display button B1 and the simple parameter display M2, a cloth feed amount setting button B5 in the front-rear direction until the next sewing pattern to be sewn is displayed.

When the CPU 101 detects the input of the cloth feed amount setting button B5, it performs display processing of the numerical value input sub-screen G3 (FIG. 9). On the numerical value input sub-screen G3, numerical value increase/decrease buttons B6 for changing the numerical value of the cloth feed amount and numerical value determination buttons B7 for determining the value of the cloth feed amount are displayed.

On the numerical input sub-screen G3, when the cloth feed amount value is set and input and the input of the numerical determination button B7 is detected, the CPU 101 cancels the display of the numerical input sub-screen G3, and displays the continuous sewing data setting screen Processing of G1 (Fig. 10). At this stage, the cloth feed amount set by the above-mentioned cloth feed amount setting button B5 is displayed on the continuous sewing data setting screen G1. In addition, below the cloth feed amount setting button B5, the sewing data candidate display button B1 of the sewing pattern to be sewn is displayed for the second time. When the input of this sewing data candidate display button B1 is detected, COU101 performs the process of switching display to sewing data candidate selection screen G2 (FIG. 11) similarly to the previous time.

On the sewing data candidate selection screen G2, a plurality of sewing data selection buttons B2 registered as candidates are displayed on the lower stage. And, when the sewing data selection button B2 of sewing pattern No. 2 is input and the input of the OK button B4 is detected, the CPU 101 switches the display to the continuous sewing data setting screen G1 ( FIG. 12 ) again. deal with. At this stage, 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 sewing pattern is displayed next to the sewing data candidate display button B1. The simple parameter of No.2 shows M2.

When the sewing data of a new sewing pattern is selected, CPU101 updates and stores continuous sewing data in RAM103, a nonvolatile memory, etc.

Therefore, according to the above processing, continuous sewing data consisting of sewing patterns No. 1 and No. 2 are formed. This continuous sewing data is registered as continuous sewing pattern No. 1.

In addition, what is necessary is just to repeat the process of FIG. 9 - FIG. 12, when adding a sewing pattern further.

(Set the acceptance switching process of input data)

Hereinafter, the switching process of whether to accept any setting input of a plurality of continuous sewing patterns or combination data combining individual sewing patterns, continuous sewing data, and individual sewing data will be described.

When setting these various data, in any screen display state, the data to be set and input can be selected by inputting the mode switching switch W1 in the above-mentioned fixed switch.

When this input is detected, CPU101 performs the process of switching display on setting data selection screen G4 (FIG. 13). On this setting data selection screen G4, a setting data selection button B8 is displayed. The setting data selection button B8 displays three kinds of data (individual sewing data, combination data, and continuous sewing data) which accept setting input in the upper, middle and lower segments respectively, and the acceptable data segment is colored and displayed.

That is, in FIG. 13 , the state in which the continuous sewing data of the lower stage can be set and input is selected, and the colored display position and the input data can be switched for each input operation of the setting data selection button B8. Fig. 14 is the second input operation from the state of Fig. 13, and the state of input combination data can be set.

In this way, when the data to be set and input is selected, the setting input screen of each data can be switched by using the input mode selector switch W1 again.

(Continuous sewing data, individual sewing data, etc. combined data creation process)

Here, it is taken as an example to input the combination data of three combinations for the continuous sewing pattern No. 1 setting.

When it is detected that the combination data is selected and confirmed by the above-mentioned setting input data acceptance switching process, the CPU 101 displays the combination data setting screen G5 ( FIG. 15 ) on the operation panel 20 based on the image data stored in the ROM 102 . .

Then, on the upper stage of the combination data setting screen G5, a combination pattern switching button B9 indicating the current combination pattern No. and a sewing position display M3 using each data included in the combination data are displayed. The sewing position display M3 displays button cursors during the current setting input, and the determined cursors are switched and processed into circle numeral icons in accordance with the sewing order (refer to FIG. 18 ).

Moreover, when the input of combined-pattern switching button B9 is detected, CPU101 displays the selection screen (illustration omitted) of another combined pattern, and accepts selection.

In addition, in the lower half of the screen, a sewing data selection button B10 is displayed at the center, and cursor display position change buttons B11 are displayed in the directions of up, down, left, and right around the button B10. The cursor display position changing button B11 is used only for changing the display position of the button cursor on the sewing position display M3, and has nothing to do with the actual sewing position.

When the input of the sewing data selection button B10 is detected, the CPU 101 switches the display to the individual sewing data candidate selection screen G6 ( FIG. 16 ).

In the individual sewing data candidate selection screen G6, a plurality of sewing data selection buttons B12 registered as candidates are displayed in the lower half. Moreover, the screen scroll button B13 which shows the other sewing data button B12 which is not displayed is displayed beside it. When the input of any one of the above-mentioned sewing data selection buttons B12 is detected, the button B12 is made to be in the temporary selection state of black and white reverse display, and various setting values and temporary selection values of the temporarily selected sewing data are displayed on the upper section. Select the OK button B14. When the input of the OK button B14 is detected, the selected individual sewing data are combined with the combined data.

Moreover, the sewing data type switching button B15 is displayed on the upper stage of the individual sewing data candidate selection screen G6. When the input of this switching button B15 is detected, CPU101 performs the process of switching display to continuous sewing data candidate selection screen G7 (FIG. 17).

On the continuous sewing data candidate selection screen G7, a plurality of continuous sewing data selection buttons B16 registered as candidates are displayed on the lower stage. Moreover, the screen scroll button B17 which can display the other continuous sewing data selection button B16 which is not displayed is displayed beside it. When the input of any one of the above-mentioned continuous sewing data selection buttons B16 is detected, the button B16 is made to be in the temporary selection state of black and white reverse display, and each of the sewing data at the head of the temporarily selected continuous sewing data is displayed on the upper stage. Confirm button B18 for setting values and temporary selection. When the input of the determination button B18 is detected, the selected continuous sewing data are combined with the combined data.

According to the above-mentioned example, when the continuous sewing pattern No. 1 selection and confirmation input are detected on the continuous sewing data candidate selection screen G7, the CPU 101 performs the display transition again to the combined data setting screen G5 (Fig. 18). processing. On the sewing position display M3 of the combination data setting screen G5, since the continuous sewing data of the first continuous sewing pattern No. The circled number 1 icon for data registration. And, a button cursor is displayed below it.

In addition, according to the example, when registering the second and third continuous sewing pattern No.1, the same operation as the registration of the first continuous sewing pattern No.1 is repeated twice, that is, (1) Input Sewing data selection button B10, (2) input sewing data type switching button B15 on the individual sewing data candidate selection screen G6, (3) input sewing pattern No.1 on the continuous sewing data candidate selection screen G7 Select and confirm.

When registering the second and third continuous sewing pattern No.1, three continuous sewing pattern No. Since the continuous sewing data of 1 is displayed, three icons of circle numbers No. 1, No. 2 and No. 3 can be displayed in parallel.

In addition, although the button cursor is displayed below it, since it is overwritten and updated when new continuous sewing data or individual sewing data is added in this combined data creation process, final confirmation input is not required. . That is, at this stage, as combined pattern No. 1, the registration of combination data combining three continuous sewing patterns No. 1 has already been completed.

(Description of buttonhole sewing machine operation)

FIG. 20 is a flowchart of the sewing operation process of the buttonhole sewing machine 10 executed by the CPU 101 of the control mechanism 100 according to the program stored in the ROM 102 . In addition, FIG. 21 shows the sewing screen switched from the combination data setting screen G5 (refer to FIG. 19 ) in which the combination pattern No. 1 is selected, and the sewing start switch W2 in the fixed switch of the operation panel 20 is input. G8.

When the input of the above-mentioned sewing start switch W2 is detected, the COU101 sets the count value n for counting the number of sewing data registered in the combination data (both continuous sewing and individual sewing data are counted as one). is 1 (step S1).

Moreover, COU101 performs display of sewing screen G8 (FIG. 21) as mentioned above. On the upper stage of the sewing screen G8, the current sewing data display M4 is displayed. On this current sewing data display M4, a plurality of circular number icons corresponding to the number of sewing data registered in the combination data are displayed in parallel. Since three continuous sewing data are registered in combination pattern No. 1, 1 to 3 are displayed as circle number icons. In addition, each circular number icon displays the sewing data icon currently being sewn in a darker color than other icons.

On the lower stage of the sewing screen G8, when the sewing data currently being sewn is individual sewing data, detailed setting values of the sewing data are displayed. In addition, when the sewing data currently being sewn is continuous sewing data, detailed setting values of the sewing data currently being sewn are also displayed in the continuous sewing data.

Then, the combination data to be sewn is referred to by the CPU 101 to know the number of sewing data registered therein. Specifically, since three continuous sewing data of continuous sewing pattern No. 1 are registered in combination pattern No. 1, the number of sewing data to be judged and confirmed is automatically set to three. Then, compare and judge that the sewing data number 3 is confirmed with the above-mentioned count value n, and when it exceeds 3 (n>3), the process of ending sewing is performed (step S2: "Yes").

In step S2, because at this stage, continuous sewing or individual sewing is before starting, since n=1 (step S2: "No"), so wait for the cloth to be placed on the sewing position (step S3). At this stage, when the user of the sewing machine arranges the sewing start position of the cloth under the machine needle 11 and instructs the lowering operation of the presser foot frame 42 by using the presser foot lift input pedal 44b, the CPU 101 detects it, and Operational control to start driving the sewing machine motor 32 is performed.

By driving the sewing machine motor 32, the CPU 101 refers to the sewing data registered in the nth number of combination data based on the current count value n, and performs sewing according to the data (step S4). Specifically, when sewing is performed according to the continuous sewing data of continuous sewing pattern No. 1, sewing is performed according to the sewing data of sewing pattern No. 1 contained therein. Also, the cutter driving solenoid 74 is driven once to a plurality of times in accordance with the buttonholes to be formed to form buttonholes on the cloth.

In addition, at this time, the current continuous sewing pattern No. is displayed, and the sewing screen G8 ( FIG. 21 ) that also displays the currently sewn sewing pattern No. included therein and its content is displayed.

And, when the sewing of the sewing pattern No. 1 included in the continuous sewing pattern No. 1 is finished, the sewing machine motor 32 is stopped, and the sewing machine motor 32 is driven to follow the setting to the next sewing pattern No. 2. The cloth feed amount value is fixed, and the cloth is moved by the presser foot frame 42 (step S5).

Then, when the cloth is conveyed, the sewing machine motor 32 is driven again, and the COU 101 sews according to the sewing data of the sewing pattern No. 2 included in the continuous sewing data of the continuous sewing pattern No. 1 which is the current count value 1. (step S6).

At this time, a sewing screen G8 ( FIG. 22 ) showing the current continuous sewing pattern No. 1 and the sewing pattern No. 2 currently being sewn included therein and its content is displayed.

When the sewing of the sewing pattern No. 2 included in the continuous sewing pattern No. 1 is completed, the sewing machine motor 32 is stopped, and the presser foot frame 42 is moved upward by the drive of the presser foot lifting solenoid 44 (step S7). In this way, the sewing of the first continuous sewing pattern No. 1 is completed. And CPU101 adds 1 to the counter value n (step S8).

Moreover, CPU101 performs display of sewing screen G8 (FIG. 23) as mentioned above. The current sewing data displayed on the upper stage of the sewing screen G8 shows the circle number icon of M4, and the second circle number icon consistent with the count value n is displayed in a dark color.

In addition, the meaning of the continuous sewing pattern No. 1 as the continuous sewing data of the subsequent sewing and its various setting values are displayed in the lower stage.

And CPU101 returns a process to step S2, and compares count value n and the number of sewing data of combination pattern No. 1.

If the count value does not exceed the specified value 3, wait for the new sewing data for the material to be sewn according to the continuous sewing data of the second continuous sewing pattern No. 1 registered in the combination data. The input of the positioning and presser foot lifting input pedal (step S3).

Hereinafter, the processing of steps S4 to S8 is performed in the same manner as above, and the processing of steps S2 to S8 is repeated in the same manner again. Then, the count value n=4, and the process of step S2 ends sewing.

In addition, in the above-mentioned embodiment, it is an example of a continuous sewing pattern in which two sewing patterns are continuously sewn three times. For the sake of making two sewing patterns.

For example, when the shape of the presser foot is formed so that three sewing patterns can be continuously sewn, three sewing patterns can be set on the continuous sewing pattern. The continuous sewing data of the sewing data is regarded as continuous sewing pattern No.3, and when sewing, it can also be automatically set to detect the continuous sewing pattern No.3, and form S4 sewing in Figure 20 on the CPU102. Pattern making and execution are the processing as a repeating mechanism that repeats the S5 repeated cloth feeding process three times.

By utilizing the shape of the presser foot in this way, the number of sewing patterns for continuous sewing can be arbitrarily increased to 4, 5, 6....

In addition, when continuous sewing and individual sewing are mixed, the number of sewing patterns can be set to 2 to 3 or more according to the number of sewing patterns detected during continuous sewing, and the number of repeated patterns for individual sewing can be set. As a method of 1, the number of repetitions processed by the CPU 102 as the above-mentioned repetition mechanism is sewn.
