[Disclosure of Invention]

[Problems to be solved by the invention]

However, in the conventional sewing machine, the continuous operation can be performed only within a range in which a cloth does not have to be replaced by the cloth pressing means, that is, in the case where a plurality of buttonhole stitches are formed in the frame without pressing up the sewing cloth. For this reason, in the case of a sewing operation in which the buttonhole of a first button (in a topmost position) in a direction perpendicular to a buttonhole-arranging direction (a vertical direction) and subsequently a buttonhole in a vertical direction from a second button to a fifth button For example, as formed in a polo shirt, the conventional sewing machine performs a series operation by setting a continuous sewing operation from the buttonhole of the second button to that of the fifth button and can not perform continuous operation for the buttonhole of the first button and the remaining buttonholes. When the suturing means are raised to change the fabric after the buttonhole of the first button is formed, it is necessary to perform a new data input operation to perform a next continuous sewing operation. Therefore, it is a disadvantage that sewing can not be carried out efficiently and quickly enough.

It is an object of the invention to efficiently and quickly perform a sewing job including a continuous sewing operation.

[Means for Solving the Problems]

A first aspect of the invention is directed to a sewing machine according to claim 1.

With the structure, data for generating the sewing data may be set and input by the input means, or present sewing data may be previously inputted to the storage means by the input means or other means. Further, the same operation can be performed also for the continuous sewing data.

The input means specifies the continuous sewing data or the individual sewing data together with the sewing order. To At this time, the combination of a plurality of continuous sewing data may be specified or the combination of at least one continuous data value and at least one sewing data value may be specified.

The control means starts the sewing operation in accordance with the continuous sewing data or the individual sewing data in a specified order, referring to the storage means. The needle and the cloth are successively positioned by the moving means relative to each other, and the descending operation of the needle is performed by the driving means to obtain a needle locating designated by the individual sewing data for execution of the sewing operation or needle localization which is indicated by the sewing data included in the continuous sewing data.

Further, in the case where a sewing object forms the continuous sewing data, a sewing operation based on a plurality of sewing data included therein is performed in order with the sewing-presser means continuously set in a pressing state.

In the structure, every time the sewing operation is carried out in accordance with the individual sewing data or the continuous sewing data, it is necessary to re-press the cloth by the cloth pressing means. Accordingly, each time the sewing operation is performed based on the individual sewing data or the continuous sewing data, the control means once stops sewing and resumes the repressurization of the squeeze-pressing means and executes the sewing operation based on the next individual sewing data or continuous sewing data , With respect to the repressurization performed by the squeeze-pressing means, the user of a sewing machine can perform re-pressing of the workpiece, and then can input the completion of the re-pressing, or a sensor for detecting the pressing of the squeeze-pressing means can be provided.

A second aspect of the invention has the same structure as that of the first aspect of the invention, and further comprises display means according to claim 2.

With the structure, the same function as that of the first aspect of the invention can be obtained, and further, a display for specifying the continuous sewing data used for the sewing operation and a display for specifying any of the continuous sewing data values used for the sewing operation are obtained on the display means in the case where the sewing operation is performed based on any of the continuous sewing data. In the case where the sewing operation is performed based on any of the individual sewing data values, moreover, a display for specifying the individual sewing data on the display means used for the sewing operation is obtained.

Advantage of the Invention

According to the first aspect of the invention, the combination of a plurality of continuous sewing data or the combination of the continuous sewing data with the individual sewing data is previously input and stored, and a transition to sewing based on the next sewing data can be made when the re-depression the suture presser means is detected for each one of the continuous sewing data values or individual sewing data values. As a result, unlike the prior art, it is not necessary to input a sentence and to input an instruction for a next process each time the cloth is depressed by the cloth pressing means. Thus, the sewing process can be performed quickly and efficiently.

Furthermore, a sewing operation may be performed as a serial operation based on a plurality of continuous sewing data which conventionally can not be performed. As a result, sewing can be done more efficiently and more quickly.

Also, in the case where there are a large number of sewing steps based on the continuous sewing data, or when individual sewing data needs to be performed for a sewing material, it is still possible to collectively set and input them collectively as a series sewing data group. Thus, it is possible to lower the frequency of setting and inputting and to carry out the work continuously. Thus, the work can be done faster and more effectively.

According to the second aspect of the invention, display means are provided, and the display means specify and represent the continuous sewing data used for the sewing operation, as well as the sewing data included therein or the individual sewing data. Therefore, the worker on the sewing machine can immediately recognize a step which is performed for the sewing operation. Further, it is possible to use the sewing data used for the sewing immediately before repressing detect. Therefore, even if the repressing is performed by the squeeze pressing means, it is possible to avoid the generation of an error in a squeeze pushing position.

The buttonhole sewing machine 10 has an operating panel 20 on that one in 3 illustrated input means in which an operator performs various settings and operations that are required for the sewing process. 4 is a front view showing the appearance of the operation panel 20 , The operating panel 20 and the sewing machine body are connected to each other by a cable or a radio circuit, which is not shown. As in 3 shown is the operating panel 20 with a display part 22 provided, which forms a display means for displaying various setting and operating conditions of the sewing machine. The display part 22 is a so-called touch panel, and various setting inputs described below are executed by means of various buttons that are displayed. Furthermore, it is also under the display part 22 the operating panel 20 a fixed switch 21 for input various settings and operations provided. Each fixed switch 21 performs a constant function, regardless of the circuit of the display.

Each main parameter, by the operating panel 20 is set includes: the width of a knife (the knife 71 is interchangeable and the width of the attached knife 71 is entered), the size of the Nähdrückdrückerrahmens 42 (the squeeze frame 42 can be replaced with respect to a frame with a different size in the longitudinal direction, and the width of the attached Nähdrückdrückerrahmens 42 is inputted, various sets of continuous sewing data having a plurality of sewing data for determining various sewing patterns, an interval between the sewing patterns in the execution of sewing in accordance with various sewing data, and a sewing machine speed (the number of revolutions of the sewing machine motor 32 ).

Here, the sewing pattern indicates a pattern for forming a buttonhole seam for a buttonhole.

More specifically, with respect to the sewing data, a width in the longitudinal direction of a buttonhole to be made, a length in the longitudinal direction of a seam lock, a stitch pitch, a needle pivot width in a transverse direction, the stitch pitch of a seam lock portion, and the width of a space between the buttonhole and every stitch on both left and right sides. The user of the sewing machine sets these parameters individually and can register them as individual sewing data for each sewing pattern by setting and inputting to a RAM 103 what will be described below or in a non-volatile recording memory. Further, the present individual sewing data, each obtained by presetting the parameters, can be externally stored in RAM 103 or the non-volatile recording memory.

Various sewing data have sewing pattern numbers respectively specified in the registry and are stored together with the sewing pattern numbers. In addition, the reading is made in accordance with the sewing pattern numbers.

Further, the continuous sewing data is formed from a combination of a plurality of sewing data in the case where the sewing operation is to be performed based on a plurality of sewing patterns within a range in which the sewing operation is performed with the sewing material presser frame down 42 (without changing a fabric presser position), and also include data in the sewing order based on each sewing data value and a sewing interval (a feeding amount). The user of the sewing machine set these parameters individually and selects them beforehand from a sewing data group stored in RAM 103 or the non-volatile recording memory, and combines and registers them again as a continuous sewing data value. Further, the present continuous sewing data with each parameter of the preset continuous sewing data can be previously stored out of RAM 103 or registered in non-volatile recording memory.

It is assumed that the sewing data indicates data for forming a single sewing pattern, and "individual sewing data" indicates individual sewing data and sewing data indicating re-depression of the cloth presser frame 42 require sewing data before and after sewing in the sewing process when they are included in combined data, which will be described below. More specifically, the same data is similar to the sewing data included in the continuous sewing data in terms of the structure of the data, and such a definition is assumed to be given for better explanation.

Further, various continuous sewing data have continuous sewing pattern numbers respectively specified in the registry and are stored together with the continuous sewing data numbers. Furthermore, the reading is made in accordance with the continuous sewing data numbers.

The buttonhole sewing machine 10 is characterized in that a plurality of continuous sewing data are combined with each other or the continuous sewing data and the individual sewing data are combined, and the sewing operation is continuously performed by interposing a work of re-squeezing work (a pressing position change regulating work) by the squeeze pressing means 40 with each continuous sewing data value or all continuous sewing data and sewing data.

5 shows the control system of the buttonhole sewing machine 10 , As in 5 shown, the buttonhole sewing machine 10 control means 100 on, which are connected to the sewing machine motor 32 , the needle pivot motor 57 , the feed motor 53 , the knife driving electromagnet 74 , the pusher-up input pedal 44b and the operating panel 20 , The control means 100 control the rotational speed of the sewing machine motor 32 , the drive timing and the swivel range of the Needle swing motor 57 , the feed amount of a sewing material by the feed motor 53 , the switching of the upward and downward movements of the Nähdrückdrückerrahmens 42 and the timing of the downward movement of the knife 71 , The control means 100 close a CPU 101 one, a ROM 102 , the ram 103 and an input / output interface 104 , The ROM 102 , the ram 103 and the I / O interface 104 are over a bus with the CPU 101 connected.

The sewing machine motor 32 is with the input / output interface 104 via a sewing machine motor driver 32a connected. An encoder 32b for detecting the number of revolutions of the sewing machine motor 32 is with the sewing machine motor driver 32a connected, so that a feedback control can be performed.

Further, a sensor 32c for the upper position of the needle to determine that the needle 11 is raised with the sewing machine motor driver 32a connected. As a result, the number of stitches in forming a seam through the needle 11 through the control part 100 counted.

Furthermore, the feed motor 53 with the input / output interface 104 via a feed motor driver 53a connected. Next to it is the knife drive electromagnet 74 with the input / output interface 104 via a knife drive circuit 74a connected.

In addition, the up / down solenoid is 44 with the input / output interface 104 via a drive circuit 44a and the pusher-up input pedal is also connected to the "pusher up" 44b with the input / output interface 104 connected.

The CPU 101 works different, in ROM 102 saved programs using the RAM 103 so that the control means 100 accept the setting and input of the continuous sewing data and the individual sewing data on the sewing pattern (sewing data, on the basis of which the sewing operation is performed individually, are referred to as single sewing data to make a distinction from the sewing data included in the continuous sewing data), and it continues to execute sewing control based on all set data.

A description will be given of a method of setting and inputting the continuous sewing data by the control means 100 , In the invention, it is assumed that various sewing data is already used as the initial value in the RAM 103 or stored in non-volatile memory.

(Process of continuous sewing data acquisition)

The control means 100 With the structure described above, the following various operations perform in accordance with various programs. Each of the operations is described in order.

Here, the case will be described in which continuous sewing data is set and input with a combination of sewing patterns No. 1 and No. 2.

First of all, the CPU shows 101 on the operating panel 20 a continuous sewing data setting screen G1 ( 6 ), based on image data stored on the ROM 102 are recorded. A display M1 in the continuous sewing data setting screen indicates a continuous sewing pattern number. A button B1 for a sewing data waiting or sewing data pre-selection display is displayed below the display M1. When the input of the button B1 for displaying a sewing data preselection or waiting is detected, the CPU performs 101 a switching operation of the display on a Nähdatenwartschafts selection screen G2 ( 7 ).

On the sewing data waiting selection screen G2, in a lower screen area, a plurality of sewing data selection buttons B2 registered as an entitlement are displayed. Further, on one side of the screen, a scroll button B3 is displayed to represent another Nähdatenauswahlknopfes B2, not shown. When the input of any of the sewing data selection buttons B2 is detected, an operation of performing a circuit on a black-and-white inversion display is performed via the button B2. In this state, the selection is still set in a provisional selection state which is not decided, and in a top screen area, various set values of sewing data preliminarily selected in the lower area and a tentative selection decision button B4 are displayed.

In the sewing data waiting selection screen G2, the sewing data selection button B2 having the sewing pattern number 1 is input. When the input of the decision making button B4 is detected, the CPU performs 101 Further, a process of turning on a display on the continuous Nähdateneinstellschirm G1 again ( 8th ). In this state, the sewing pattern number is displayed on the sewing data waiting display button B1 of the continuous sewing data setting screen G1. Further, a simple parameter display M2 having the pattern number 1 is displayed next to the sewing data waiting display button B1.

Then, a feed amount adjusting knob B5 in a longitudinal direction to a sewing pattern to be used in a next sewing operation is displayed below the sewing data expectation display button B1 and the simple parameter display M2.

When the input of the feed amount adjusting knob B5 is detected, the CPU performs 101 a process of displaying a numerical value input sub-screen G3 ( 9 ). On the numerical value input sub-screen G3, there are shown a numerical value increase / decrease button B6 for changing the numerical value of the feed amount and a decision button B7 for a numerical value for deciding the value of the amount of feed.

In the numerical value input screen G3, when the value of the feed amount is set and input, and further, the decision button B7 input is detected, the CPU clears 101 the display of the input sub-screen G3 of the numerical value and performs a process of displaying the continuous sewing data setting screen G1 ( 10 ). In this state, the feed amount set on the feed amount setting button B5 on the continuous sewing data setting screen G1 is displayed. Further, the sewing data pre-selection display button B1 having such a sewing pattern to be sewed secondly is shown under the feed amount adjusting knob B5. When the input of the sewing data waiting indication button B1 is detected, the CPU performs 101 an operation of switching the display to the sewing data waiting selection screen G2 in the same manner as the last time (FIG. 11 ).

The sewing data preset selection screen G2 displays a plurality of sewing data selection buttons B2 registered as a candidate in the lower screen area. Then, the sewing data selection button B2 is input with the sewing pattern number 2. When the input of the decision button B4 is detected, the CPU performs 101 continue to turn on the display of the continuous sewing data setting screen G1 (FIG. 12 ). In this state, the sewing pattern number is displayed on the second sewing-data-waiting display button B1 of the continuous sewing data setting screen G1, and the simple parameter display M2 with the sewing pattern No. 2 is displayed next to the sewing-data-waiting display button B1.

Each time the sewing data is newly selected with the sewing pattern, the CPU updates and registers 101 the continuous sewing data in RAM 103 or in the non-volatile memory.

Accordingly, the continuous sewing data with the sewing patterns No. 1 and No. 2 are formed by the process. This continuous sewing data is registered as the continuous sewing pattern No. 1.

In the case where a sewing pattern is still added, it suffices that the processes in 9 to 12 be repeated.

(Process of setting and inputting the data accepting circuit)

A description is given of a process of switching acceptance acceptance of setting and inputting any combined data obtained by combining a plurality of continuous sewing patterns with a single sewing pattern and continuous sewing data with individual sewing data.

In the case where various data setting operations have to be performed, it is possible to select, in each of the display states, data set and input by the input of a mode changeover switch W1 in the fixed switch.

When the input of the mode changeover switch W1 is detected, the CPU performs 101 an operation of switching the display to a setting data selection screen G4 ( 13 ). On the setting data selection screen G4, a setting data selection button B8 is shown. The setting data selection button B8 displays three types of data (the individual sewing data, the combined data and the continuous sewing data) for the purpose of accepting the setting and input by itself in upper, middle and lower screen areas, respectively, and further provides a colored display for one Level of data that is acceptable.

More in detail is in 13 the state enabling the setting and input of the continuous sewing data is selected in the lower area, and a coloring display position and data which can be input are switched at each input operation for the setting data selection button B8. 14 shows a state in which the input operation is in the state of 13 is executed twice, and the combined data can be set and input.

Thus, when the data to be set and entered is selected, it is possible to generate a circuit for each data set and input. Switch screen by re-entering the mode changeover switch W1.

(Process of obtaining combined data from continuous sewing data and individual sewing data)

The case in which the combined data obtained by combining three continuous sewing pattern numbers 1 are set and input will be described.

When the selection and decision of the combined data by the switching operation of acceptance of the set and input data is detected, the CPU shows 101 on the operating panel 20 a combined data setting screen G5 based on image data stored in the ROM 102 are recorded ( 15 ).

Then, in the upper stage of the combined data setting screen G5, a combination pattern switching button B9 representing a current combination pattern number and a sewing position indication M3 to be executed by all the data included in the combined data are displayed. With reference to the sewing position display M3, a knob cursor is displayed during the setting and input, and the data which is decided is subjected to a process of performing switching to the display of a numerical circular image icon in accordance with the sewing order (see FIG 18 ).

When the input of the combination pattern switch button B9 is detected, the CPU shows 101 also selects another combination pattern selection screen (not shown) and accepts a selection.

Further, in the center of the lower stage of the screen, a sewing data selection button B10 is displayed, and a cursor change position button B11 is displayed around the button B10 for each vertical and lateral direction. The cursor display position change key B11 is used only to change the display position of a button cursor in the sewing position display M3 and is not related to an actual sewing position.

When the input of the sewing data selection button B10 is detected, the CPU performs 101 a switching operation of the display on a selection screen G6 for an individual sewing data expectancy ( 16 ).

On the prospective selection screen G6 for individual sewing data, a plurality of sewing data selection buttons B12 registered as a candidate are displayed in the lower area thereof. Further, on one side of the screen, a scroll button B13 for displaying another sewing data selection button B12 not shown is displayed. When the input of any of the sewing data selection buttons B12 is detected, the button B12 is set in the preliminary selection state of a black and white display, and various set values of the preliminary selected sewing data and a tentative selection decision button B14 are displayed in an upper screen area. When the input of the decision button B14 is detected, the selected individual sewing data is included in the combined data.

Further, in the upper stage of the individual sewing data waiting or preselection selection screen G6, a sewing data type button B15 is shown. When the input of button B15 is detected, the CPU performs 101 a switching operation on the display on a selection screen G7 concerning a continuous sewing data pre-selection ( 17 ).

At the continuous sewing data pre-selection selection screen G7, at a lower stage thereof, a plurality of continuous sewing data selection buttons B16 registered as a candidate are displayed. Further, on a screen side, a scroll button B17 for displaying another continuous sewing data selection button B16, not shown, is shown. When the input is detected from any one of the continuous sewing data selection buttons B16, the button B16 is set in the preliminary selection state of a black-and-white inversion display, and various set values of the main sewing data of the continuous sewing data, which have been preliminarily selected, and a tentative selection decision button B18 are set in FIG an upper screen area shown. When the input of the decision button B18 is detected, the selected continuous sewing data is included in the combined data.

When the input of the selection and decision of the continuous sewing pattern No. 1 is made on the continuous sewing data pre-selection selecting screen G7 in accordance with the example described above, the CPU performs 101 an operation to switch the display back to the combined data setting screen G5 ( 18 ). Referring to the sewing position representation M3 of the combined data setting screen G5, continuous sewing data having a first continuous sewing pattern No. 1 has already been included. As a result, in an original button cursor position, an icon with a numeric circle number 1, which indicates a first data registration of a combination. A button cursor is displayed in a lower part.

In the case where second and third continuous sewing patterns No. 1 are to be registered in accordance with the embodiment, the same operations as the registration of the first continuous sewing pattern No. 1, that is, the first sewing pattern No. 1 will be registered. H. (1) the input of the sewing data selection button B10, (2) repeats the input of the sewing data type button B15 on the prospective selection screen G6 for the individual sewing data; and (3) the input of the selection and decision of the sewing pattern No. 1 on the selection screen G7 for the continuous sewing data pre-selection twice ,

When the second and third continuous sewing patterns No. 1 are registered, three picture symbols with numbering circles Nos. 1, 2 and 3 are arranged and shown in three data registrations as shown, since the continuous sewing data with three continuous sewing patterns No. 1 in the sewing position display M3 of the combined data setting screen G5 are included ( 19 ).

Then the button cursor is displayed in a lower part. In this combined data acquisition process, an overwriting and updating is performed each time new new sewing data or sewing data is added. Therefore, it is not necessary to finalize the decision. In other words, in the present step, the combined data obtained by combining three continuous sewing patterns No. 1 are already registered as a combination pattern No. 1.

(Explanation of the operation of the buttonhole sewing machine)

20 FIG. 10 is a flow chart showing the procedure of sewing the buttonhole sewing machine. FIG 10 which of the CPU 101 the control means 100 in accordance with a program to be executed in ROM 102 is stored. Further shows 21 a sewing screen G8 which is turned on by the input of a sewing start switch W2 in the fixed switch of the operation panel 20 starting from the combined data setting screen G5 (see 19 ) in which the combination pattern No. 1 was selected.

When the input of the sewing start switch W2 is detected, the CPU stops 101 a count value n for counting the number of sewing data registered in the combined data to 1 (step S1) (counting each of the continuous sewing data and the individual sewing data as one).

As described above, the CPU shows 101 also the sewing screen G8 ( 21 ). A continuous sewing data display M4 is obtained at the top of the sewing screen G8. On the continuous sewing data display M4, a plurality of number-circle image symbols are arranged and displayed in accordance with the number of sewing data registered in the combined data. With the combination pattern No. 1, three continuous sewing data are registered. As a result, the number circle icons 1 to 3 are displayed. Furthermore, each of the number-circle image symbols performs a more color-containing representation than other image symbols of the sewing data, due to which the sewing operation is performed.

In the case where the sewing data on which the sewing operation is performed is individual sewing data, each of the detailed set numerical values of the same sewing data is displayed in the lower portion of the sewing screen G8. Further, in the case where the sewing data on which the sewing operation is performed is the continuous sewing data, each of the detailed numerical values of the continuous sewing data on which the sewing operation is to be performed is further displayed.

The CPU 101 refers to the combined data on the basis of which the sewing operation is to be performed, and recognizes the number of sewing data that is registered. More specifically, three continuous sewing data are registered with the continuous pattern No. 1 with the combination pattern No. 1. Therefore, 3 is automatically set to the number of sewing data to be discriminated and recognized. Then, the recognized sewing data number 3 and the counted value n are compared with each other and thus determined, and a process for finishing the sewing operation is executed when 3 is exceeded (n> 3) (step S2: YES).

In the step S2, the continuous sewing or the single sewing is not started yet, and n = 1 is set in the present state (step S2: NO). As a result, the cloth is caused to wait for the setting of a sewing position (step S3). When the user of the sewing machine has a sewing sewing start position under the needle 11 provides and an instruction for the lowering process of the Nähdrückdrückerrahmens 42 in this state by means of the pusher-on input pedal 44b enters, sets the CPU 101 determines the input of the instruction and controls a process for starting the drive of the sewing machine motor 32 ,

By the driving process of the sewing machine motor 32 refers to the CPU 101 n-th registered sewing data of the combined data in accordance with the consecutively counted value n and executes the sewing operation in accordance with this data (step S4). More specifically, the sewing operation in the case where the sewing operation is carried out in accordance with the continuous sewing data with the continuous sewing pattern No. 1 is carried out in accordance with the sewing data with the sewing pattern No. 1 included therein. Further, the knife driving electromagnet becomes 74 At least once driven according to a buttonhole to be formed, and the buttonhole is formed on the fabric.

At this point the sewing screen G8 ( 21 ) for displaying a continuous continuous sewing pattern number, a sewing pattern number enclosed therein with which the sewing operation is performed, and contents thereof.

When the sewing operation with the sewing pattern No. 1 included in the continuous sewing pattern No. 1 is finished, the sewing machine motor will continue to be 32 stopped and the fabric is from the Nähgutdrückerrahmen 42 in accordance with a set feed amount value by the drive operation of the feed motor 53 to a next sewing pattern number 2 (step S5).

When the cloth is shifted, the driving operation of the sewing machine motor becomes 32 restarted and the CPU 101 performs the sewing operation in accordance with the sewing data with the sewing pattern No. 2 included in the continuous sewing data with the continuous sewing pattern No. 1, with a consecutively counted value of 1 (step S6).

At this time, the sewing screen G8 is displayed ( 22 ) for mapping the continuous continuous pattern number 1, the pattern number 2 enclosed therein, and with which the sewing is performed, as well as their contents.

When the sewing operation with the sewing pattern No. 2 included in the continuous sewing pattern No. 1 is finished, the sewing machine motor becomes 32 stopped and the Nähdrückdrückerrahmen 42 is due to the driving process of the up / down electromagnet 24 moved upward (step S7). As a result, the first sewing operation with the continuous sewing pattern number 1 is completed. Then the CPU adds 101 to the count value n 1 (one) (step S8).

As described above, the CPU shows 101 continue to attach the sewing screen G8 ( 23 ). With reference to a number-circle image symbol for the continuous sewing data display M4 obtained at the top of the sewing screen G8, a second number-circle image symbol coinciding with the counted value n is displayed in a rich color.

Further, the content that a sewing operation to be performed has the sewing pattern No. 1 of the continuous sewing pattern No. 1 of the continuous sewing data, and various setting values thereof are shown in the lower portion.

Then the CPU performs 101 returns the process to step S2 and compares the count value n with the number of sewing data having the combination pattern No. 1.

If the count value does not exceed 3, which is to be a previously defined value, it is waited for the input of a new cloth positioning and pusher input pedal for performing the sewing operation in accordance with the continuous sewing data using the continuous sewing pattern No 1, which is a second sewing data registered in the combined data (step S3).

The operations of steps S4 to S8 are carried out in the same manner as described above, and further, the operations of steps S2 to S8 are similarly repeated once more. Thereafter, a count value n = 4 is set, and the sewing operation is ended by the process of step S2.

While the example in which the continuous sewing pattern for continuously sewing two sewing patterns is repeated three times in the embodiment is described here, the reason is that the pusher shape (the shape or size of the fabric presser frame 42 ) is taken in such a way that the two sewing patterns can be sewn continuously.

For example, in the case where the pusher shape is such that three sewing patterns can be continuously sewn, it is possible to set three sewing patterns to the continuous sewing pattern. In this case, the continuous sewing data registering three sewing data are registered as the continuous sewing pattern number 3 in approximately the same operation as described above, and the continuous sewing pattern No. 3 is detected in the sewing process, and the CPU 102 can also be automatically set to the process flow of repetition means to repeat the formation of the sewing pattern from S4 and the feed operation from S5 in 20 to exercise three times.

Thus, the number of sewing patterns for the continuous sewing can optionally be increased to 4, 5, 6 ... depending on the pusher shape.

In addition, in the case where the continuous sewing and the single sewing are mixed with each other, the number of sewing patterns is judged, and the number of sewing patterns of 2, 3 or more is the number of times in the process flow of the CPU 102 are set to be the repeating means in the continuous sewing operation, and the number of repeating patterns is set to 1 in the simple sewing operation. Thus, the sewing process can be performed.

(Advantage of the embodiment)

At the buttonhole sewing machine 10 For example, the combination of a plurality of continuous sewing data or the combination of the continuous sewing data with the individual sewing data are input in advance and in the RAM 103 stored by the input and setting operation control 100 , and the set position of the sewing material on the sewing machine is shifted at each continuous sewing data value or individual sewing data values. When pressing the pusher-on pedal 44b is determined, therefore, the renewed depression of the Nähdrückdrückerrahmens 42 of the Nähgutdrückermittels 40 to proceed to the sewing process based on the next sewing data. For this reason, it is not necessary to carry out adjustment and input as well as operation instruction input each time the re-squeezing of the suturing material is performed by the squeeze pressing means unlike the prior art. As a result, the sewing process can be performed quickly and efficiently.

Further, it is possible to perform a sewing process as a serial process, which is performed several times by a plurality of continuous sewing data and the combination of the continuous sewing data with the individual sewing data, which has conventionally not been carried out. As a result, it is possible to do the sewing work more efficiently and quickly.

Also, in the case where there are a large number of sewing steps based on the continuous sewing data or the individual sewing data to be performed across a fabric, it is still possible to collectively process them as a standard sewing data group simultaneously by the input and output stitches Setting process of the CPU 102 set and enter, and they in RAM 103 hold. As a result, the frequency of setting and inputting can be reduced, and the work can be carried out continuously. Thus, it is possible to perform the work faster and more effectively.

It also specifies and shows the CPU 101 distinguishably all the registration data in the continuous sewing data for a continuous sewing, and the sewing data included therein or the individual sewing data on the display part 22 the operating panel 20 in accordance with the execution of a program, and further sets various set values related to each sewing data. As a result, the operator of the sewing machine can immediately recognize the running sewing pattern and its contents. Furthermore, the kind and contents of the sewing data to be executed are displayed immediately before the repressing operation. Even if the re-pressing of the Nähdrückdrückerrahmen 42 the Nähgutdrückermittel 40 Therefore, it is possible to avoid a situation in which a press position for the cloth is erroneously adjusted due to erroneous recognition of the sewing data, thereby maintaining the accuracy of work.

Although the buttonhole sewing machine has been described in the embodiment, the invention is applicable to other sewing machines for obtaining sewing data on a sewing block unit and sewing for all stitching data. For example, the invention can be applied to a pattern sewing machine for forming seam patterns in various patterns and for performing the sewing operation on this unit.

Although the description has been made for the case where the combined data is constituted by a plurality of continuous sewing data in the embodiment, it is also possible to combine the continuous sewing data with the individual sewing data.

The up / down actuating means may also be implemented by a further actuator, for example a pulse motor or an air cylinder, instead of the electromagnet.
