Description

HEMSTITCH SEWING MACHINE AND HEMSTITCH FORMING METHOD}

The present invention relates to a coiling sewing machine and a coiling needle stitch forming method.

Conventionally, the coiling sewing machine includes a cloth conveying mechanism for conveying a processed cloth, a sewing mechanism for forming needle stitches in the processed cloth, a pair of zigzag needle stitches and a pair of bartack needle stitches by controlling the cloth conveying mechanism and the sewing mechanism. And a control device for forming a stitch needle stitch. Then, a button hole forming mechanism including a cutter for forming a button hole in the fabric is provided, the button hole forming mechanism is controlled by a control device, and the stitch needle stitch is subjected to a series of operations including the formation of the stitch needle stitches. In some cases, a button hole is formed inside.

In addition, the sewing mechanism is basically a needle bar, a needle mounted on the lower end of the needle bar and mounted with an upper thread extending from the upper thread source, a needle bar vertical movement mechanism for driving the needle bar up and down, and a needle bar rocking mechanism for oscillating left and right. And a bobbin attached to the lower side of the needle plate (transport stand) and the lower thread wound, and an upper thread in the vicinity of the needle moving up and down from the lower side of the needle plate to entangle the lower thread extending from the bobbin. It has a real ring capture | collector.

By the way, with respect to the stitch needle stitches (for example, a square stitch needle stitch) formed on the fabric by the stitching sewing machine, for example, as in the stitch stitch stitch 70 of FIG. The width of 74 is wider than the width of the zigzag needle stitches 71 and 72, and most of the needle stitch pitches of the bartack needle stitches 73 and 74 (distance from the needle drop point to the next needle drop point; for example, 3.5 mm). Is longer than the needle stitch pitch (for example, 1.5 mm) of the zigzag needle stitches 71 and 72.

In this way, most of the needle stitch pitches of the bartack needle stitches are so long that when sewing the bartack needle stitches, the processing cloth near the bartack needle stitches is pulled by the thread and is likely to crumble and wrinkle. That is, it is difficult to form neat entangling needle stitches, and the above problem becomes more remarkable when the bartack needle stitches are formed on a processed cloth made of a material having high elasticity or a thin cloth thickness.

Here, it is conceivable to reduce the tension applied to the upper thread through the balance and the thread conditioner when sewing the bartack needle stitch so that the processed fabric near the bartack needle stitch is pulled by the thread and not wrinkled. Bartack needles will not be able to tighten properly.

In addition, when the bartack needle sweat is formed on the processed cloth made of brushed material such as knit, the bartack needle sweat easily penetrates deeply into the lower side of the brushed part of the processed cloth, and the aesthetic appearance of the bartack needle sweat also deteriorates. .

And when forming the zigzag needle stitch of the needle stitch which is wound around processing cloth having high elasticity and thin cloth thickness, the processing cloth of the zigzag needle stitch is pulled up by a thread, and it is easy to crumble and wrinkle, There is also a risk of not forming needle stitches.

As a technique for solving this problem, there is a needle stitch processing method described in JP-A-54-38838. In this method, as shown in Fig. 1, a plurality of reinforcing needle stitches 301 are formed in a straight line on each of the left and right pairs of zigzag needle stitch formation scheduled portions to reinforce the fabric, and then the zigzag needle stitches 302 are continuously formed. To form.

However, in this method, only a plurality of reinforcing needle stitches 301 are formed and reinforced in the zigzag needle stitch formation scheduled portion, and the bartack needle stitch formation scheduled portion is not reinforced at all. It is easy to be pulled by and shriveled up and wrinkled, and it is difficult to form neat entangling stitches.

Moreover, in the conventional stitching machine, after the formation of the stitching needle stitch or during the formation of the stitching stitch stitch, the inside of the stitching stitch stitch (between the zigzag stitches on the right and left of the stitching stitch stitch) based on the cutter drive position data. Lower the cutter to form the buttonhole.

However, in the case where the lower thread is consumed during the formation of the stitch needle stitches, the button hole is formed by the button hole forming mechanism in a state in which a defective stitch stitch is formed.

In this way, when the buttonhole is formed by the buttonhole forming mechanism in a state in which the defective stitching stitches are formed in the processed fabric, if the stitching stitch is formed again without performing any processing on the fabric, in particular, the buttonhole When forming the zigzag needle stitches of the needle stitches on both sides of the fabric, the processing cloth may be easy to move, and the processing cloth may be pulled by the thread, causing the crease to crease, and the button hole is also easy to expand in the width direction. Can't form neat entwine stitches.

In the case of forming the stitching needle stitches in the processed fabric made of brushed material such as knit, the stitching needle stitches easily penetrate into the lower side of the brushed portion of the processed cloth, and there is a problem that the aesthetics of the stitching needle stitches is deteriorated. In order to solve this problem, it is possible to consider measures to form the stitch needle stitch after polymerizing cloth or paper on the site where the stitch needle stitch is to be formed, but there is a possibility that the workload becomes large, the work efficiency is reduced, and the aesthetic appearance is also deteriorated. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for forming a stitching machine and forming stitching needle stitches, to easily and surely form the bartack needle stitches of the neat stitching stitch stitches, and to form the bartack needle stitches by appropriately tightening them. Enhancing the aesthetics of the bartack needle stitches formed on the processed fabric made of brushed material, reinforcing a pair of bartack needle stitch formation scheduled portions to enable the formation of neat bartack needle stitches, and having a defective stitching stitch on the fabric Even when the buttonhole is formed in the state of forming the shape, the neat stitch stitch is simply and reliably formed after that, and the aesthetic appearance of the stitch stitch formed on the processed cloth made of the raised material is improved.

Each variable (for example, the zigzag pitch of the number "04") can be set within a setting range (0.20 to 2.00 mm), and 1 of the up-down key 99 of the operation panel 4 when the setting is performed. Increase / decrease by one step (0.05 mm) by one push operation. Moreover, the initial value (0.35 mm in the zigzag pitch of number "04") of each variable is set. The setting range data, step data, and initial value data are stored in the R0M 5b of the control device 5 corresponding to the numbers of the plurality of variables.

Here, as shown in Fig. 13, the stitch stitch shape of the number “01” includes (a) a square, (b) a radial, and (c) an annular shape, and although not shown, there are a plurality of arbitrary forms. In the case of setting the stitch stitch shape, as shown in Fig. 9, after switching to the program mode using the operation panel 4, for example, the display unit 98 is displayed in a state where &quot; 01 &quot; If "0" is displayed on the display, it is possible to set it to the square of (a). 15, a is a cutter dimension of number "02", b is a zigzag pitch of number "04", c is a zigzag width of number "05", d is a front bartack length of number "20", e Represents the rear bartack length of the number "30".

In particular, as the plurality of variables for sealing, as shown in Fig. 11, the number of sewing stitches with the number "45", the number of mountain-shaped seals with the number "46", the number of rectangular sewings with the number "47",. And number of gabon bartack Y needles (valid only for mountain Gabon) with the number "54", and corresponding to the number of these variables, the setting range data, the step data and the initial value data are R0M (5b) of the control device 5. It is stored in.

Here, among the plurality of variables shown in Figs. 9 to 12, most of variables other than those of the numbers "45" to "54" in Fig. 11, specifically, the numbers "01" to "11", "20" to "23" "," 30 "to" 33 "," 40 "to" 44 "," 55 "to" 58 ", and" 63 "to" 67 "are the shape and size of the needle stitches to the control device 5 Are a plurality of variables (hereinafter, referred to as buttonhole stitches).

In addition, the variable "45" is a variable regarding the setting of the sewing stitch, and when sewing the zigzag needle stitch 85, the number of sewing stitches of the number "45" is set to (1), and (0) Set to).

In this way, when suture sewing is performed with the variable "45" set to (1), a part of the stitching needle stitch variable that defines the shape and size of the stitching needle stitch (specifically, numbers "02", "05", Variables of "07", "20", "22", "30" and the numbers "49" to "52" define the shape and size of the zigzag needle stitch 85 with respect to the control device 5. It functions as a plurality of variables (hereinafter referred to as gaussian variables). In this manner, a part of the stitching stitch sweat parameter is utilized as the gaussian variable.

On the other hand, the variable "46" is a variable for setting the mountain type gabon, and when the reinforcement needle stitches 185 and 186 and the stitching needle stitches 187 and 188 are subjected to the sealing, the number of mountain type gabons of the number "46" is (1). If not set, the value is set to (0).

As described above, in the case of performing mountain-type gabon with the variable "46" set to (1), a part of the wiping needle stitch variable (specifically, numbers "02", "05", "07", "20", "22") ”,“ 30 ”) and the variables“ 49 ”to“ 54 ”in Fig. 11 are a pair of reinforcing needle stitches 185 and 186 and a pair of needle stitches 187 for the control device 5. , 188), which functions as a plurality of variables (which correspond to the Gaussian variable) defining the shape and size of the 188 element. As such, even in this case, a part of the stitch stitch variable is utilized as the gaussian variable.

The variable &quot; 47 &quot; is a variable for setting the rectangular gabon, and is provided to the plurality of reinforcing needle stitches and the bartack needle stitch forming portions 73a and 74a in each of the zigzag needle stitch forming scheduled portions 71a and 72a. In this case, when stitching a plurality of needle stitches for stitching, the number of times of rectangular stitching with the number "47" is set to any one of (2-5), and is set to (0) when not performing the rectangular stitching with the number "47". . 31 (a) to (d), the number of rectangular stitches of the number "47" is set to (3), and the three reinforcing needle stitches 285a are formed in the zigzag needle stitch forming scheduled portions 71a and 72a. 285c, 287a-287c, and the case where three hook stitches 286a-286c, 288a-288c are performed at each bartack needle-formation formation part 73a, 74a are shown.

As described above, in the case of performing rectangular sewing by setting a number other than (0) to the variable "47" (particularly, numbers "02", "05", "07", and "20") , "22", "30" variable, and the numbers "47", "49" to "52" are for the reinforcing needle stitches 285a to 285c, 287a to 287c, It functions as a plurality of variables (hereinafter referred to as gamma line parameters) that define the shape and size of the needle stitches 286a to 286c and 288a to 288c. As such, even in this case, a part of the stitch stitch variable is utilized as the gaussian variable.

Next, the control executed by the control device 5 will be described with reference to the flowchart in FIG.

In this case, no sewing is performed, and the case of sewing the stitching needle of the square in Fig. 15 will be described as an example.

This control is started at the same time as the power supply of the winding sewing machine M, the initial setting S1 is performed, and then the variable setting processing S2 is performed. In this variable setting process, for example, immediately after the power is turned on, an initial value stored in the R0M 5b is set to a plurality of variables shown in Figs. 9 to 12. As described above, a plurality of variables are used using the operation panel 4 as described above. It can be reset by changing the setting value of the variable. Here, in order not to form the zigzag needle stitches 85, the number of stitchings of the number "45" is set to (0), and the number of types of stitchings of the mountain "46" and the number of "47" are also used so as not to perform other sewing. Set the number of rectangular stitches to (0).

Next, when the "ENTER" key 100 is operated to finish setting the variables (S3; YES), the set values of the plurality of variables are read (S4), and the stitch stitches 70 are wound based on these set values. Sewing data (needle drop data) is calculated (S5), cutter drive position data for lowering the cutter 61 is calculated (S6), and these data are recorded in the RAM 5c.

In S5 and S6, sewing data and cutter drive position data are created specifically as follows.

Here, the stitch stitch formation scheduled portion is defined based on the stitch stitch stitch parameters as shown in FIG. In the figure, a is cutter dimension "02", b is zigzag pitch "04", f is cutter X space "06", c is zigzag width "05", d is front bartack length "20", e Is the rear bartack length `` 30 '', g is the front bartack pitch `` 21 '', h is the rear bartack pitch `` 31 '', i is the cutter Y space `` 07 '', j is the zigzag width `` 05 '' + front bartack Width correction "22" and k are prescribed | regulated by zigzag-shaped width "05" + rear bartack width correction "32".

In addition, the home position (0, 0) is defined in the center of the front end of the stitching needle stitch, and assumes a rectangular coordinate system having an X axis in the needle drop direction and a Y axis in the cloth feed direction. The region of the y-coordinate 0 to d is the front bartack needle sweat formation part 73a, and the region of the y-coordinate d to (d + a + 2i) is the zigzag needle stitch formation part 71a, 72a, and y The region whose coordinates are (d + a + 2i) to (d + a + 2i + e) is the rear bartack needle stitch formation scheduled portion 74a.

Therefore, the data of the left zigzag needle stitches 71 indicates that the needle stitches are on the left end portion (x coordinate:-f / 2) of the cutter hole forming portion 71a and the left end portion of the left zigzag needle stitch forming portion 71a. x coordinate:-f / 2-c), they are created so as to be formed side by side as pitch b in the y direction alternately.

Similarly, the data of the right zigzag needle stitches 72 shows that the needle stitches are on the right end portion (x coordinate: f / 2) of the cutter hole forming portion scheduled portion and the right end portion (x coordinate: f /) of the right zigzag needle stitch forming portion 72. On 2 + c), they are created such that they are alternately also formed side by side as pitch b in the y direction.

Further, the data of the rear bartack portion 74 indicates that the needle stitches are on the left end portion (x coordinate: -f / 2-k) and the right end portion (x coordinate: f / 2 + k) of the rear bartack needle stitch formation scheduled portion 74a. ) Are alternately formed side by side as pitch h in the y direction.

The data of the front bartack portion 73 indicates that the needle stitches are on the left end portion (x coordinate: -f / 2 -j) and the right end portion (x coordinate: f / 2 + j) of the needle bar forming portion 73a. ), So as to alternately form side by side as the pitch g in the y direction.

The cutter drive position data indicating the cutter drop position is formed by the needle stitch position on the right end (x coordinate: f / 2) of the cutter hole formation scheduled portion, among the data of the right zigzag needle stitch 72. Therefore, whenever the needle reaches the right end of the cutter hole formation scheduled portion, the cutter is driven to form a hole.

Subsequently, when the pedal 3 is depressed (S7; YES), the cloth transfer mechanism 10 and the sewing mechanism 30 are driven and controlled based on the sewing data stored in the RAM 5c to perform sewing processing (S8). ) Is executed. In addition, the sewing process may be executed while calculating the sewing data up to the number of needle stitches, or the sewing process may be started after all the sewing data has been calculated.

Thereafter, based on the cutter drive position data stored in the RAM 5c, when the cutter 61 reaches the cutter drop position at the stage where the cutter 61 forms zigzag needle stitches 71 and 72 on both sides of the fabric to be conveyed. After the sewing is temporarily stopped (S10), the cutter 61 is driven to descend by the button hole forming mechanism 60 (S1l), so that the button hole 80 is formed. The driving position of the cutter 61 is a predetermined position during or immediately after the formation of the right zigzag needle stitch 72.

After that, when sewing is not finished (Sl2; no), the process returns to S7, and when the pedal 3 is depressed (S7; yes), sewing is resumed in the sewing process of S8, and the stitch needle stitch ( 70 is finished (S12; YES), the process returns to S2.

By performing the above operation, the stitch needle stitch 70 of Fig. 15 is formed.

By the way, in the case where the lower thread is consumed during the formation of the stitch stitch 70, for example, as shown in Fig. 17, the buttonhole 80 is formed in a state where the stitch stitch 70a having a defect is formed in the fabric. ) Is formed.

In this case, the sewing is finished, or by forced termination, the process proceeds to the variable setting processing of S2, where the zigzag needle stitches 85 are formed (sealed) on both sides of the button hole 80 and then wound. The setting process of the variable can be performed again to again form the needle stitches 70.

That is, in this time variable setting process S2, using the operation panel 4, the number of sealing stitches of the number "45" is changed to (1), and it resets. The set values of the variables of the numbers "46" to "52" may be reset from the initial values to the desired values within the setting range. At this time, although the setting values of variables other than the numbers "45" to "54" can be changed and reset, since the button hole 80 is already formed, the size of the stitch stitch 70 is particularly relevant. It is preferable not to change the setting value of a variable, and it shall also do so in this embodiment.

Next, after the variable setting processing (S2), when the "ENTER" key 100 is operated to set the variable (S3; YES), the set values of the plurality of variables of numbers "45" to "52" Read (S4), and then in S5, a plurality of variables (corresponding to the seam line variable, which define the shape and size of the zigzag needle stitches 85 formed by the suture sewing rod, the plurality of numbers "45" to "52"). Sewing data of the zigzag needle stitches 85 of FIG. 18 is calculated based on the setting values of the parameters of the zigzag needle stitches 85 of FIG. . Incidentally, the calculated sewing data is used for the sewing data of the stitch needle 70 in FIG. 19, and the calculated cutter drive position data is used in S6.

Here, about the sewing data of the zigzag stitches 85, the formation of the zigzag stitches 85 is started from the formation scheduled portion of the front bartack stitches 73 near the sewing start point of the stitch stitch 70. The scheduled portion of the rear bartack needle stitch 74 is repeatedly formed along the button hole 80 to form a zigzag needle stitch 85 in a reciprocating manner and is calculated on sewing data ending at the sewing start point.

Here, as shown in Fig. 20, the pitch of the zigzag needle stitches 85 is obtained by dividing the length in the front-back direction of the portion scheduled to form the stitch needle stitches by a predetermined integer (8 in this example).

Therefore, the data of the zigzag stitches 85 is alternately pitched in the y direction on the left end of the stitch stitch formation scheduled portion and the right end of the stitch formation scheduled portion [in this example, (d + a + 2i + e) / 8].

The x-coordinate of the left end of the stitch stitch formation scheduled portion is-f / 2-c in the left zigzag needle stitch formation scheduled portion 71a,-f / 2-k in the rear bartack formation scheduled portion 74a, and the front side. In the bartack formation scheduled part 73a, it is -f / 2-j. In addition, the x-coordinate of the right end of the winding formation scheduled portion is f / 2 + c in the right zigzag needle stitch formation scheduled portion 72a, f / 2 + k in the rear bartack formation scheduled portion 74a, and front bartack formation. In the predetermined part 73a, it is f / 2 + j.

In addition, the needle stitch data of the zigzag needle stitches 85 may be created so that the zigzag needle stitches are formed slightly inside of the scheduled portion for forming the stitching needle stitches. In this manner, by forming the zigzag stitches in the sewing area of the stitch stitches, the zigzag stitches can be covered with the stitch stitches.

Subsequently, when the pedal 3 is depressed (S7; YES), in the sewing process of S8, first, based on the sewing data of the zigzag stitches 85 stored in the RAM 5c, the stitch stitches 70 are wound. The cloth transfer mechanism 10 starts to form the zigzag needle stitches 85 from the vicinity of the sewing start point, and forms the zigzag needle stitches 85 in a reciprocating manner along the buttonhole 80 and ends at the sewing start point. And the sewing mechanism 30 are driven to control the zigzag needle stitch 85 of FIG.

After the formation of the zigzag stitches 85, the pedal 3 is depressed (S7; YES), and the cloth transfer mechanism 10 is based on the sewing data of the wound stitches 70 stored in the RAM 5c. ) And the sewing mechanism 30 are driven to control the sewing process (S8), and the formation of the stitch stitch 70 is performed again as shown in FIG. After the formation of the wound needle stitch 70 again performed, the cutter of the button hole forming mechanism 60 is cut based on the cutter drive position data in order to cut the portion crossing the button hole 80 among the zigzag stitches 85. Drive control 61).

The action and effect of performing the said sealing temporary sealing are demonstrated.

As described above, the buttonhole is formed by the buttonhole forming mechanism 60 in the state in which the defective stitch stitch 70a is formed in the fabric, such as when the lower thread is consumed during the formation of the stitch stitch 70. When the 80 is formed, the cloth transfer mechanism 10 and the sewing mechanism 30 are controlled by the control device 5 to form a zigzag needle stitch 85 covering both sides of the button hole 80. Then, the formation of the wound needle stitch 70 can be performed again.

That is, even when the buttonhole 80 is formed in a state where the defective stitching stitches 70a are formed in the fabric, the stitching stitches 70 (in particular, the buttonholes in the stitching stitches 70) are formed on the fabric. When the zigzag needle stitches 71 and 72 formed on both sides of the 80 are again formed, the zigzag needle stitches 85 are formed after the zigzag needle stitches 85 are formed. It can be pulled out to prevent wrinkles. Therefore, the button hole 80 also becomes difficult to expand in the width direction, and finally, the neat stitching stitches 70 can be simply and reliably formed.

In addition, in the case of the processing cloth which consists of raising materials, such as knitted fabric, since the raised part of the processing cloth can be knocked down to some extent by the zigzag-shaped needle stitch 85, the stitching needle stitch 70 raises the raised cloth in that part. It becomes difficult to dig into the lower side of the negative part, and the aesthetics of the stitching stitch 70 which is performed again is further improved.

After the formation of the rewind needle stitch 70, the button hole forming mechanism 60 is controlled by the control device 5, and in the zigzag needle stitch 85 by dropping the cutter inside the rewind needle stitch 70. The part crossing the buttonhole 80 can be cut | disconnected. In other words, by effectively using the button hole forming mechanism 60, the portion of the zigzag needle stitch 85 that crosses the button hole 80 can be reliably cut, and finally the button hole 80 can be reliably opened. Will be.

When the control device 5 controls the cloth transfer mechanism 10 and the sewing mechanism 30 to form the zigzag needle stitch 85, the front bartack needle stitch 73 near the sewing start point of the stitch needle stitch 70 is formed. ), The formation of the zigzag needle stitches 85 is started from the scheduled to be formed, and the zigzag needle stitches 85 are reciprocated to be reciprocated by folding back the site for forming the rear bartack needle stitches 74 along the button hole 80. In order to finish at the sewing start point, the zigzag needle stitches 85 can be formed over the entire lengthwise direction of the button hole 80, and further, after the zigzag needle stitches 85 are formed, they are continuously wound. Needle stitches 70 can be formed.

Using the operation panel 4, a plurality of variables (gap line variable; variables of numbers '49' to '52', etc.) that define the shape and size of the zigzag needle stitches 85 can be set. Since the plurality of twist stitch needle variables defining the shape and size of 70 are utilized as the stitch line variable, the setting number can be easily performed by reducing the number of newly set settings of the stitch line variable. The shape and size of the zigzag needle stitches 85 corresponding to 70 can be easily set.

Next, the modification of the suture temporary rod is demonstrated.

1) In the wound sewing machine M, the button hole (before starting sewing of the wound needle stitch 70 by controlling the cloth feed mechanism 10 and the sewing mechanism 30 by the control device 5). The zigzag stitches 85 may be formed on both sides of the portion to be formed 80.

In this case, using the operation panel 4, the number of sewing stitches of the number &quot; 45 &quot; is set to (1) from the beginning, and the shape and size of the stitch stitch 70 and the zigzag stitches 85 are prescribed. This can be done by setting the variable to be used and depressing the pedal 3.

In addition, after formation of the stitch needle 70, the button hole forming mechanism 60 is controlled, and the zigzag needle stitch 85 is dropped by dropping the cutter in the formation scheduled portion of the button hole inside the stitch needle 70. The button hole 80 can be formed at the same time as the site | part which cut | disconnects the button hole formation plan part of the middle is cut | disconnected.

Here, the step of forming the zigzag needle stitches 85 on both sides of the scheduled portion of the button hole 80 corresponds to the first step, and the wiping needle stitches 70 on the zigzag needle stitches 85 are formed. The forming step corresponds to the second step.

This makes it possible to reinforce the processed fabric by the zigzag stitches 85, which is advantageous for preventing the fabric from being deformed and forming the neat stitching stitches 70. When the processed cloth is a processed cloth made of brushed material such as knit, Since the raised part of the processing cloth can be knocked down to some extent by the zigzag stitching 85, it is difficult for the enveloping needle stitch 70 to dig into the lower side of the raising part of the processing cloth, and the enveloping needle stitch 70 I can improve the aesthetics of.

2) In addition, in the above description, if the pedal 3 is continuously pressed in, the zigzag stitches 85 formed on both sides of the button hole 80 are formed, and then the formation of the stitch stitches 70 is continuously repeated. Although it is comprised, you may comprise so that the selection and sewing of the stitching needle stitch 70 and the zigzag needle stitch 85 may be performed independently.

3) The sewing data of various stitch stitches, sewing data of zigzag stitches, and also various cutter drive position data are stored in advance, and among them, the sewing data of desired stitch stitches and sewing stitches of zigzag stitches and The cutter drive position data may be selected and set to drive control the cloth feed mechanism, the sewing mechanism, and the button hole forming mechanism.

4) The zigzag needle stitches 85 can be applied to various zigzag needle stitches, including known three-point zigzag needle stitches and four-point zigzag needle stitches, without being limited to two-point zigzag needle stitches that form needle stitches alternately from side to side. In this case, a plurality of zigzag needle stitches may be prepared, so that the desired zigzag needle stitches can be set by parameter determination.

Next, before sewing the square stitching stitches 70 of FIG. 15, the control in the case of performing the mountain-shaped gabon forming the reinforcing stitches 185 and 186 and the stitching stitches 187 and 188 in FIG. do.

In this case, in the variable setting process (S2; Fig. 14), the number of mountain-type stitching with the number &quot; 46 &quot; is set to (1) in order to perform stitching of the reinforcing needle stitches 185 and 186. In addition, the set values of the variables "48" to "54" can also be set back to desired values within the setting range. Here, the number of stitching stitches with the number "45" and the number of rectangular stitches with the number "47" is set to (0) so as not to perform other stitching.

For this reason, in S5, sewing data of the stitching needle stitch 70 is calculated based on a plurality of variables that define the size and shape of the stitching needle stitch 70, and a plurality of variables of the numbers "45" to "54". And a pair of reinforcing needle stitches (185, 186) and a pair of striking needle stitches (187, 188) based on a gaussian variable consisting of a portion of the stitching needle stitch variable that defines the shape and size of the stitching needle stitch 70 (70). ) Sewing data is calculated.

Here, in S5, first, as shown in Figs. 21 and 22, sewing needle stitch 187, reinforcing needle stitch 186, hanging needle stitch 188, and reinforcing needle stitch 185 are sewn in this order. Sewing data is calculated so that a portion of the front bartack needle stitch 73 of the stitching needle stitch 70, the left zigzag needle stitch 71, the rear bartack needle stitch 74, and the right side as shown in FIG. Sewing data is calculated to sew the remaining portions of the zigzag stitches 72 and the front bartack stitches 73 in this order. That is, the sewing data of the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188 starts sewing from the vicinity of the sewing start point of the stitching needle stitch 70 and then sewing at the sewing start point. It is calculated on the sewing data to end.

Here, as shown in Fig. 24, the distance between the stitching needle stitches 187 and 188 and the length in the left and right directions of the reinforcing needle stitches 186 and 185 are, for example, the left and right zigzag needle stitch forming portions 71a, It is determined at a predetermined ratio with respect to the width in 72a).

In addition, the length of the front-back direction of the reinforcement needle stitches 186 and 185 can be calculated | required as the predetermined ratio of the corresponding front bartack length d, and the predetermined ratio of the rear bartack length e, respectively.

The pitch of the front and rear reinforcement needle stitches 186 and 185 can be obtained by dividing the length in the left and right directions in the front and rear reinforcement needle stitches 18b and 185 by a predetermined constant (8 in the present embodiment).

That is, the data of the stitch stitch 187 for stitching is created so that the stitch stitches are lined up in order at the sealing pitch "49" on a straight line extending in the y direction at the x coordinate:-f / 2-c (predetermined ratio).

Similarly, the data of the stitching needle stitches 188 are also created so that the stitches are lined up in order at the sealing pitch "49" on a straight line extending in the y direction at the x coordinate: f / 2 + c · (predetermined ratio).

Further, the data of the reinforcing needle stitch 186 indicates that the needle stitch is between the x coordinate:-f / 2-c · (prescribed ratio) and the x coordinate: f / 2 + c · (prescribed ratio). ) On the front end (y coordinate: d + a + 2i) and the rear end [y coordinate: d + a + 2i + e · (predetermined ratio)] on the scheduled to be formed, the pitch [for example, in the x direction] is alternately , (2 · c · (predetermined ratio) + f) / 8].

Similarly, the data of the reinforcing needle stitch 185 indicates that the needle stitch is between the x coordinate:-f / 2-c · (predetermined ratio) and the x coordinate: f / 2 + c · (predetermined ratio). ) On the rear end (y coordinate: d) and the front end [y coordinate: d-d · (predetermined ratio)] on the scheduled to be formed, the pitch [for example, [2 · c · (predetermined)] is alternately in the x direction. Ratio) + f) / 8].

Here, the said predetermined ratio is a number smaller than 1 (for example, 0.8 etc.), and is fixed beforehand. Therefore, the ridge gamma line is formed in the winding needle stitch formation scheduled portion.

Accordingly, in S8, as shown in Figs. 21, 22, and 23, the needle stitch 187 for reinforcement, the needle stitch 186 for reinforcement, the needle stitch 186 for reinforcement, the needle stitch 185 for reinforcement, and the stitch needle stitch 70 (70). Sewing is successively performed in order of) (left zigzag needle stitch 71, rear bartack needle stitch 74, right zigzag needle stitch 72, and front bartack needle stitch 73).

More specifically, after S5 and S6, when the pedal 3 is depressed (S7; YES), the sewing process of S8 is performed, and as shown in Figs. 21 to 22, the ridged seams 185 to 188 are shown. Is formed. After that, when the pedal 3 is depressed (S7; YES), the sewing process S8 is executed again, and the stitch stitch 70 is formed as shown in Fig. 23, and the buttonhole 80 is formed. (S11).

The effect | action and effect which perform said mountain-shaped gabon are demonstrated.

The cloth conveyance mechanism 10 and the sewing mechanism 30 are controlled by the control apparatus 5, and it is set to the formation plan part 73a, 74a of the bartack needle stitches 73 and 74 of the wound needle stitch 70. After forming the reinforcing needle stitches 185 and 186 intersecting with the tack needle stitches 73 and 74, the bartack needle stitches 73 and 74 can be formed on the reinforcing needle stitches 185 and 186.

That is, since the bartack needle stitch forming portions 73a and 74a of the fabric are reinforced by the reinforcing needle stitches 185 and 186, the bartack needle stitches 73 and 74 are placed on the reinforcing needle stitches 185 and 186. At the time of forming, the processed fabric near the bartack needle stitches 73 and 74 is pulled out by the thread, making it difficult to wrinkle. Therefore, the bartack needle stitches 73 and 74 of the neat zipping stitches 70 can be formed simply and reliably, and furthermore, the bartack needle stitches 73 and 74 can be formed by appropriately tightening, and particularly, the elasticity is high. It becomes effective when the bartack needle stitches 73 and 74 are formed in the workpiece | work which consists of a raw material and a thin material.

In addition, in the case of the processing cloth which consists of raising materials, such as a knit, it is possible to knock down the raised part of the processing cloth to some extent by the reinforcement needle stitches 185 and 186, and in that part, the bartack needle stitches 73 and 74 are It becomes difficult to dig into the lower side of the raised part of the processing cloth, and the aesthetics of the bartack needle stitches 73 and 74 improve further. Since the reinforcing needle stitches 185 and 186 are formed in the bartack needle stitch forming portions 73a and 74a, the reinforcing needle stitches 185 and 186 can be covered with the bartack needle stitches 73 and 74, so that the bar The good appearance of the tack needles 73 and 74 is not impaired.

By using the operation panel 4, a plurality of variables defining the shape and size of the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188. ? &Quot; to &quot; 54 &quot;, but since the plurality of twist stitch needle variables defining the shape and size of the stitch stitch 70 are utilized as the stitch line variable, a setting for newly setting the stitch line variable The setting operation can be easily performed by reducing the number, and the shape and size of the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188 corresponding to the stitching needle stitches 70 are easy. Setting is possible.

Further, a pair of reinforcing needle stitches 185 and 186 formed in the pair of bartack needle stitch forming portions 73a and 74a, respectively, and a pair of zigzag needle stitch forming portion 71a without cutting the thread. , 72a), a pair of stitching needle stitches 187 and 188 respectively formed in succession can be formed continuously, and the work of forming a pair of reinforcing needle stitches 185 and 186 can be simplified. Further, in order to start the formation of these reinforcing needle stitches 185 and 186 and the stitching needle stitches 187 and 188 from the vicinity of the sewing starting point of the winding needle stitch and end at the sewing starting point, the reinforcing needle stitches and the stitching needle stitches After the formation is continued, the stitching stitches 70 can also be formed continuously.

Modifications of the above-mentioned mountain Gabon will be described.

1) Before forming the bartack needle stitches 73 and 74 of the wound needle stitch 70, the pair of scheduled needle stitches 187 and 188 is not formed, and the scheduled part of the bartack stitches 73 and 74 is formed. The reinforcing needle stitches 185 and 186 intersecting with the bartack needle stitches 73 and 74 may be formed at the 73a and 74a. In this case, the bartack needle stitches 73 and 74 may be discontinuously sewn.

2) In the above description, if the pedal 3 is continuously pressed in, the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188 are formed, and then the formation of the wound needle stitch 70 is formed. Although it is configured to continuously perform the step, the sewing of the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188 and the stitching of the stitching needle stitch 70 may be performed independently. good.

3) In the above description, the pair of reinforcing needle stitches 185 and 186 and the pair of stitching needle stitches 187 and 188 are formed, and then the stitching needle stitch 70 is formed. (Or 186), the bartack needle stitch 73 (or 74) may be continuously formed on the reinforcing needle stitch 185 (or 186).

4) The sewing data of various stitch stitches, reinforcement stitch stitches and stitch stitch stitch data, or various cutter drive position data are stored in advance, and among them, desired stitch stitches and reinforcing stitch stitches and stitch stitch stitches are stitched. Data and cutter drive position data may be selected and set to drive control the cloth feed mechanism, the sewing mechanism, and the button hole forming mechanism.

5) Other Modifications of Mount Gabon

Next, another modification of the mountain Gabon will be described.

In this modification, in addition to the mode in which the reinforcing needle stitches 185 and 186 are not formed before the bartack needle stitches 73 and 74 are formed in the bartack needle stitch formation scheduled portions 73a and 74a, as shown in FIG. As shown in Fig. 26 (or Fig. 28), the first mode of forming the reinforcing needle stitches 185 and 186 on both of the bartack needle stitch formation scheduled portions 73a and 74a as shown in Fig. 26 (or Fig. 28). It is comprised so that setting is possible in any one of the 2nd modes which form the reinforcement needle stitch 185 (or 186) only in the formation plan part 73a (or 74a).

In the first mode, the control device 5 is formed in a pair of bartack needle stitch forming portions 73a and 74a, respectively, as shown in Figs. The cloth conveying mechanism (185, 186) and the pair of stitching needle stitches 187, 188 formed to terminate the pair of zigzag needle stitch forming scheduled portions 71a, 72a, respectively, are continuously formed. 10) and the sewing mechanism 30 are configured.

In the second mode, when the reinforcing needle stitches 186 are formed only in the rear bartack needle stitch forming portions 74a among the pair of bartack needle stitch forming portions 73a and 74a (see Fig. 26), the front bar Any method may be set in the case where the reinforcing needle stitches 185 are formed only in the tack needle stitch forming portion 73a (see Fig. 28).

When the reinforcing needle stitches 186 are set to be formed only in the rear bartack needle stitch forming portion 74a, as shown in Figs. 26 and 27, the control device 5 is the rear bartack needle stitch forming portion 74a. A reinforcing needle stitch 186 formed in the upper portion, a stitch needle stitch 110 formed to cross the front bartack needle stitch forming portion 73a, and a pair of zigzag needle stitch forming portions 71a and 72a, respectively. The cloth transfer mechanism 10 and the sewing mechanism 30 are controlled to continuously form a pair of needle stitches 187 and 188 formed to terminate.

Further, when the reinforcing needle stitches 185 are formed only in the front bartack needle stitch forming portion 73a, as shown in FIG. 28, the control device 5 is attached to the front bartack needle stitch forming portion 73a. Terminate the reinforcing needle stitch 185 formed, the stitch needle stitch 111 formed to cross the rear bartack needle stitch formation schedule portion 74a, and the pair of zigzag needle stitch formation schedule portions 71a and 72a, respectively. The cloth conveyance mechanism 10 and the sewing mechanism 30 are controlled to continuously form a pair of needle stitches 187 and 188 formed so as to be continuous.

Therefore, as shown in FIG. 25, as the variable of the number "46", instead of the "mount of gabon times" of the mountain gabon, a variable of "mount gabon" (corresponding to a variable for reinforcing needle stitches) is provided and controlled. By the setting processing program stored in the R0M 5b of the apparatus 5, this "mountain gabon" variable can be set using the operation panel 4 and can be set alternatively to the first and second modes, and the like. It is supposed to be. The plurality of variables other than the number "46" are basically the same as the plurality of variables in FIGS. 9 to 12 of the above embodiment.

In other words, if the reinforcement needle stitches are not formed before sewing the stitching stitches 70 on the fabric with respect to the variable "mountain gabon", (0) is set, the reinforcing needle stitches 186 only on the rear bartack side. ) Is set (see Fig. 26), and (2) is set when the reinforcing needle stitches 185 are formed only on the front bartack side (see Fig. 28). (3) is set when the reinforcing needle stitches 185 and 186 are formed on the side (see Fig. 22).

After setting a plurality of variables including the variable "mountain gabon", the stitch stitch stitches are based on the plurality of stitch stitch stitches by the data calculation processing program stored in the R0M 5b of the control device 5. When the sewing data of 70 is computed and the variable "mountain gabon" is set to any one of (1) to (3), that is, when the first or second mode is set, the plurality of gabons Sewing data for sewing, including reinforcing needle stitches, is calculated based on the line parameters.

In addition, when the cloth transfer mechanism 10 and the sewing mechanism 30 are controlled by the control apparatus 5 based on these sewing data, for example, the variable of "mountain gabon" becomes (1), FIG. As shown in FIG. 26, sewing is continuously performed in order of the stitch stitch 187, the stitch stitch 186 for the reinforcement, the stitch stitch 188 for the stitches, and the stitch stitch 110 for the stitches. In the same manner, sewing of the stitch needle 70 is performed in the order of the left zigzag needle stitch 71, the back bartack needle stitch 74, the right zigzag needle stitch 72, and the front bartack needle stitch 73 in this order.

By the way, the back bartack is formed at the front bartack needle stitch formation scheduled portion 73a at the start of sewing and at the end of the sewing of the stitch needle 70, but when the reinforcing needle stitch 185 is formed in addition to the needle stitches of the backtack, the needle stitch number ( Since the number of needle drops) increases, thereafter, needle flow interruption (phenomena where the needles do not bend and interfere with the needle stitches and do not fall to a predetermined needle drop position) or needle bending occurs when the front bartack needle stitches 73 are formed. There is a fear that the aesthetics of the bartack needle stitch 73 deteriorates.

According to the twist sewing machine of this modified example, the variable of "mountain gabon" is set to (1) (set to the second mode), and the reinforcing needle stitches only in the rear bartack needle stitch forming portion 74a in which no backtack is formed ( 186 can be formed, thereby suppressing the number of needle stitches formed in the front bartack needle stitch scheduled portion 73a, and preventing needle flow interruption and needle bending when forming the front bartack needle stitch 73, and It is possible to form the front bartack needle sweat 73 neatly so as to form a neat entangling needle sweat 70 as a whole.

Then, when set to the second mode, the stitch needle 110 (or reinforcing needle stitch 185) and the rear bartack needle stitch formed on the front bartack needle stitch formation scheduled portion 73a without cutting the thread. Reinforcement needle stitches 186 (or stitching needle stitches 111) formed in the formation scheduled portion 74a, and a pair of stitching stitches respectively formed in the pair of zigzag needle stitch forming portions 71a and 72a ( 187 and 188 can be formed continuously, and the formation work of the reinforcing needle stitch 185 (or 186) can be simplified.

Further, the formation of the reinforcing needle stitches 185 (or 186) and the stitching needle stitches 110 (or 111), 187, and 188 starts from the vicinity of the sewing start point of the wiping needle stitches 70 and ends at the sewing start point. In order to achieve this, after stitching, the stitching stitches 70 can also be continuously formed. When the first mode is set, the same operation as in the above embodiment can be obtained.

By the way, as shown in Fig. 29, there are angular, radial, circular, flow, and straight types as the front bartack needle stitches. As shown in Fig. 30, angular, radial, circular, and eyelet stitches are the types of rear bartack needle stitches. There is a brother. Incidentally, a plurality of types of constitutions of the arbitrary types of wiping needle stitches are formed by the combination of the front bartack needle stitches of FIG. 29 and the rear bartack needle stitches of FIG. 30, in addition to the stitching needle stitches of FIGS. 13A to 13C. can do. In addition, the shape of the back and forth needle bartack needles is square in Fig. 13A, the radial is in Fig. 13B, and the round is the entangling stitch in Fig. 13C.

Incidentally, depending on the shape of the bartack needle stitch, there may be a case where the formation of the reinforcing needle stitches 185 and 186 corresponding thereto is effective or invalid. Particularly, in the radial and straight lines of the plurality of types of front bartack needle stitches of FIG. 29, and the radial and eyelets of the plurality of types of rear bartack needle stitches of FIG. 30, at least a part of the stitches is wound in the longitudinal direction of the needle stitch 70. Since it is formed in the direction including the component, there is an effect such as suppressing the stretching in the longitudinal direction without forming the reinforcing needle stitches (185, 186), daring to form the reinforcing needle stitches (185, 186) front bartack You don't have to make your needle sweat look bad.

According to this modification, the reinforcing needle stitches 185 and 186 are not formed or the reinforcing needle stitches 186 are formed only on the rear bartack side according to the shape of the front bartack needle stitch and the shape of the rear bartack needle stitch. Whether to form the reinforcing needle stitches 185 only on the front bartack side, or to form the reinforcing needle stitches 185 and 186 on both the front and back bartack sides, it can be set appropriately anyway.

Further, according to the shape of the front bartack needle stitch of FIG. 29 and the shape of the rear bartack needle stitch of FIG. 30, the control device 5 does not form the reinforcing needle stitches 185, 186 or only on the rear bartack side. Either forming the reinforcing needle stitches 186, or forming the reinforcing needle stitches 185 only on the front bartack side, or forming the reinforcing needle stitches 185 and 186 on both front and back bartack sides, somehow, to be set automatically. You may comprise.

In this case, as described above, when the front bartack needle stitches are radial and straight, so as not to form the reinforcing needle stitches 185 in the front bartack needle stitch formation scheduled portion 73a, and when the rear bartack needle stitches are radial and eyelet type. It is set automatically so as not to form the reinforcing needle stitches 186 in the rear bartack needle stitch forming portion 74a.

In this case, a setting item (for example, 4) for automatic setting is provided in the variable for reinforcing needle stitches (mountain Gabon of number &quot; 46 &quot;), and the shape of the front bartack needle stitches is set only when this setting item is set. The reinforcing needle stitch may be automatically set according to the shape of the rear bartack needle stitch. Alternatively, the variable does not have to be set automatically so as to be set. In other words, even when the reinforcement needle stitch is formed to be formed in the bartack needle stitch formation scheduled portion by setting the variable of the mountain-type Gabon with the number "46", the setting is set in the case of the shape of the bartack needle stitch (radiation, etc.). It may be made to switch automatically so that it may invalidate and not form reinforcement needle stitch in the bartack needle stitch formation scheduled part.

In addition, you may apply the modified example 1)-4) of the acid type Gabon which were already described to this modification 5).

Next, at the time of forming the stitching needle stitches 70, as shown in Fig. 31 (c) prior to the formation of the stitching needle stitches 70, three sets of two (6 in total) of straight lines are formed. The control in the case of performing the rectangular sewing which forms the reinforcing needle stitches 285a to 285c and 287a to 287c and the three sets of two stitches (total 6) for the stitching stitches 285a to 285c and 287a to 287c will be described.

In this case, in the variable setting process (S2; Fig. 14), the number &quot; 47 &quot; is used to add and reinforce the needle stitches 285a to 285c and 287a to 287c and the stitch stitches 285a to 285c and 287a to 287c. Set the number of rectangular stitches to (3). In addition, the set values of the variables "48" to "52" can also be set again to desired values within the setting range. Here, in order not to perform other provisioning, the number of stitching stitches of the number "45" and the number of peaks of the mountain-shaped stitching of the number "46" are set to (0).

Therefore, in S5, sewing data of the stitch stitch 70 is calculated based on the stitch stitch stitch variable defining the size and shape of the stitch stitch, and a plurality of variables 47 and 52 and the stitch are wound. The reinforcing needle stitches 285a to 285C, 287a to 287c and the striking needle stitches 285a to 285c and 287a based on the gaussian parameters, which are part of a plurality of stitching needle stitch variables that define the shape and size of the stroke stitches 70. Sewing data from 287c to 287c is calculated and recorded in the RAM 5c.

Here, in S5, first, the reinforcing needle stitches 285a and the stitching needle stitches are arranged in the centers in the width direction of the zigzag needle stitch forming portions 71a and 72a and the longitudinal centers of the bartack needle stitch forming portions 73a and 74a. (286a), reinforcing needle stitches 287a, and stitching needle stitches 288a are sewn in this order (see Fig. 31 (a)), and then zigzag needle stitch forming portions 71a and 72a and bartack needle stitches. The reinforcement needle stitches 285b, the stitching needle stitches 286b, and the reinforcing needle stitches in the vicinity of the button hole formation scheduled portion side (for example, a position that is 0.5 mm from the button hole formation scheduled portion) among the formation scheduled portions 73a and 74a. (287b), the stitching needle stitches 288b are sewn in this order (see Fig. 31 (b)), and finally, the zigzag stitch stitch forming portions 71a and 72a and the bartack needle stitch forming portions 73a and 74a. In the vicinity of the end portion opposite to the button hole formation scheduled portion side (for example, a position 0.5 mm from the opposite end portion), STEEL stitch (285c), make immersion stitch (286c), [see (c) of FIG. 31; the reinforcing stitch (287c), so as to make the immersion sewing stitch (288c) in this order, and the sewing data is calculated.

Here, sewing starts from the vicinity of the sewing start point of the needle stitch 70 by wiping the front backtack of the reinforcing needle stitch 285a, and the sewing starting point of the stitching needle stitch 70 by winding the sewing of the stitch stitch 288c. It is calculated on sewing data ending at.

Further, subsequent to the calculation of sewing data of the reinforcing needle stitches 285a to 285c and 287a to 287c and the stitching needle stitches 285a to 285c and 287a to 287c, the front bartack needle stitch 73 of the stitching needle stitch 70 is carried out. Part of the left side, the left zigzag stitches 71, the rear bartack stitches 74, the right zigzag stitches 72, and the remaining portions of the front bartack stitches 73 in this order (Fig. 31 (d)). Reference], sewing data is calculated.

More specifically, as shown in Fig. 32, the rectangular needle stitch data is created to alternately create a straight line extending in the y direction and a straight line extending in the x direction. Here, the x-coordinate position of the straight line extending in the y direction and the y-coordinate position of the straight line extending in the x direction are obtained from the rectangular number of stitches, the gauss line variable, and the stitch stitch variable.

That is, for example, of the four straight lines 285a, 286a, 287a, and 288a for creating the first loop with respect to the rectangular number of stitches 3, the left y-direction straight line 285a has the x coordinate (-f / 2). -C / 2) extend the image, the right y-direction straight line 287a extends the x coordinate (f / 2 + c / 2) image, and the back x-direction straight line 286a is the y coordinate (d + a + 2i + e / 2), and the front x-direction straight line 288a extends the y-coordinate (d / 2) image.

Of the four straight lines 285b, 286b.287b, and 288b for creating the second loop, the left y-direction straight line 285b extends on the x coordinate (-f / 2-c / 4), and the right y-direction straight line. (287b) extends the x coordinate (f / 2 + c / 4) image, and the back side x-direction straight line 286b extends the y coordinate (d + a + 2i + e / 4) image and the front side x The direction straight line 288b extends on the y coordinate 3d / 4.

Of the four straight lines 285c, 286c, 287c, and 288c for creating the third loop, the left y-direction straight line 85c extends on the x coordinate (-f / 2-3C / 4) and the right y-direction straight line. (287c) extends the x coordinate (f / 2 + 3c / 4) image, the rear side x-direction straight line 286c extends the y coordinate (d + a + 2i + 3e / 4) image, and the front side x The direction straight line 288c extends on the y coordinate d / 4.

The needle stitch data is formed so that the needle stitches are lined up one after another at a sealing pitch "49" on each straight line.

Therefore, in S8, three straight reinforcing needle stitches 285a to 285c and 287a which are formed by moving in the width direction of the zigzag needle stitches 71 and 72 to the pair of zigzag needle stitch forming portions 71a and 72a, respectively. 287c and three hook stitches 286a to 286c and 288a to 288c respectively formed on the pair of bartack needle forming portions 73a and 74a, respectively, in a continuous loop shape three times in succession. Is formed.

In this way, as shown in Figs. 31A to 31C, three reinforcing needle stitches 285a to 285c and 287a to 287c are formed in each of the zigzag needle stitch forming portions 71a and 72a. It is formed at equal intervals in the width direction of (71, 72), and three hook stitches 285a to 285c and 287a to 287c are formed on the bartack needle stitch forming portions 73a and 74a, respectively. Are formed at equal intervals in the longitudinal direction.

More specifically, after S5 and S6, when the pedal 3 is depressed (S7; YES), the sewing process of S8 is performed, and a rectangular temporary seam line as shown to Fig.31 (a)-(c) is carried out. 285 to 288 are formed. Thereafter, when the pedal 3 is depressed (S7; YES), the sewing process S8 is executed again, and the stitch stitch 70 is formed as shown in Fig. 31D, and the buttonhole 80 This is formed (S11).

The effect | action and effect which perform the said rectangular temporary sealing are demonstrated.

The cloth transfer mechanism 10 and the sewing mechanism 30 are controlled by the control device 5, and at the time of forming the stitch needle 70, a pair of zigzags precedes the formation of the stitch needle 70. A plurality of straight reinforcing needle stitches 285a to 285c, 287a to 287c, which are formed by moving in the width direction of the zigzag needle stitches 71 and 72, respectively, on the needle stitch formation forming portions 71a and 72a, and a pair of bars. The plurality of needle stitches 285a to 285c and 287a to 287c, which are formed in the tack needle stitch forming portions 73a and 74a, respectively, are formed in a continuous shape of a plurality of times in a continuous loop without forming unnecessary needle stitches. can do.

Since the plurality of reinforcing needle stitches 285a to 285c and 287a to 287c are formed by moving in the width direction of the zigzag needle stitches 71 and 72, the zigzag needle stitches are formed in the zigzag needle stitch forming scheduled portions 71a and 72a. The predetermined portions 71a and 72a can be reinforced in a wide range, and after the reinforcement, when the zigzag needle stitches 71 and 72 are formed in the scheduled portions 72a and 72a, the zigzag needle stitches 71 72) The processed fabric in the vicinity can be pulled out by the thread, making it difficult to crease and wrinkles, thereby forming neat zigzag needle stitches 71 and 72. In addition, the zigzag needle stitch forming portions 71a and 72a are formed in a wide range by a plurality of reinforcing needle stitches 285a to 285c and 287a to 287c formed at equal intervals in the zigzag needle stitch forming portions 71a and 72a. It can be reinforced substantially evenly and becomes effective in forming the neat zigzag needle stitch 70.

In particular, since a plurality of stitch stitches 285a to 285c and 287a to 287c are formed in the pair of bartack needle stitch formation scheduled portions 73a and 74a, respectively, a pair of zigzag needle stitch formation scheduled portions 71a and 72a are formed. The plurality of reinforcing needle stitches 285a to 285c and 287a to 287c respectively formed on the pair of needle stitches 286a to 286c and 288a to 288c respectively formed on the pair of bartack needle stitches 73a and 74a, respectively. Since it can form continuously and the sewing operation can also be performed smoothly continuously, the load of a sewing machine is reduced.

That is, in the conventional case of Fig. 1, since the needle stitches 301 for reinforcing left and right positioned with the button hole interposed are not formed continuously, the sewing operation is discontinuous and is not performed smoothly. Therefore, the load of the sewing machine which repeats starting and stopping of a sewing operation became large. In contrast, in the present embodiment, the load of the sewing machine is reduced by performing the sewing operation continuously.

In addition, since the bartack needle stitch formation scheduled portions 73a and 74a can be reinforced by the plurality of hook stitches 285a to 285c and 287a to 287c, the bartack needle stitch formation scheduled portions 73a and 74a are reinforced after the reinforcement. When the bartack needle stitches 73 and 74 are formed, the processing cloth near the bartack needle stitches 73 and 74 is pulled by the thread, making it difficult to crumble and form the neat bartack needle stitches 73 and 74. It becomes possible. Further, since the needle stitches formed by moving the plurality of stitching stitches formed on the pair of bartack needle stitch formation portions 73a and 74a respectively, the bartack needle stitch formation portions 73a and 74a can be reinforced in a wide range. Can be effective in forming a neat zigzag needle stitch 70.

Reinforcement needle stitches 285a to 285c and 287a to 287c of shapes and sizes corresponding to the zigzag stitches 71 and 72 of the stitching needle stitch 70 by setting the plurality of gamma line parameters by operating the operation panel 4. ) And straddling needle stitches 285a to 285c and 287a to 287c, and the plurality of stitching needle stitches parameters may be set to form the stitching needle stitches 70 having a desired shape and size. Since a part of the plurality of stitch stitch variables is used as the Ga line variable, the number of settings for setting the Ga line variable newly can be reduced, so that the setting operation can be easily performed, which corresponds to the zigzag stitches 71 and 72. The shape and size of the reinforcing needle stitches 285a to 285c and 287a to 287c can be easily set.

Also, a plurality of reinforcing needle stitches 285a to 285c and 287a to 287c and a plurality of stitching stitches 285a to 285c and 287a to 287c are paired with zigzag stitches 71 and 72 and a pair of bartack stitches. (73, 74), respectively. Furthermore, in the case of the processing cloth which consists of raising materials, such as knitted fabric, the processing cloth is made of the plurality of reinforcing needle stitches 285a to 285c and 287a to 287c and the plurality of stitching stitches 285a to 285c and 287a to 287c. Since the raised part can be considerably knocked down, the bartack needle stitches 73 and 74 are less likely to penetrate into the lower side of the raised part of the processed fabric, and the aesthetic appearance of the bartack needle stitches 73 and 74 can be further improved.

Next, a modification of the rectangular gabon is described.

1) As shown in FIG. 33, at the time of formation of the stitch needle stitch 70, for example, 3 formed in the bartack needle stitch formation scheduled portion 74a prior to the formation of the stitch needle stitch 70. Of the two needle stitches 289a to 289c, one stitch needle 289a is formed of a needle stitch including a needle stitch which intersects the bartack needle stitch, and the other two stitch stitches 289b and 289c are formed into a sentence pattern. You may form with needle stitches. In this case, the bartack needle stitch formation scheduled part 74a can be reinforced more reliably, and it becomes effective in forming the neat zigzag needle stitch 70.

Further, the plurality of stitch stitches may be formed of stitch stitches including ridge stitches. Although not shown, among at least one stitch stitch 289a formed in the front bartack needle stitch formation scheduled portion 73a, at least one stitch stitch 289a is a needle stitch including a cross stitch stitch that crosses the bartack stitch stitch. You may form.

2) At the time of formation of the stagger stitches 70, prior to the formation of the stagger stitches 70, the zigzag needle stitches 71 and 72 are respectively provided in the pair of zigzag stitches to be formed 71a and 72a. Two or more linear reinforcing needle stitches 285a to 285c and 287a to 287c formed by moving in the width direction of and two pairs formed on the pair of bartack needle stitch forming portions 73 and 74, respectively. Alternatively, four or more stitching stitches 285a to 285c and 287a to 287c may be formed in a continuous loop in a plurality of times.

3) The plurality of reinforcing needle stitches formed in the zigzag stitches forming scheduled portions 71a and 72a may be formed by moving in the width direction of the zigzag stitches 71 and 72, and the zigzag stitches 71 and 72. It is not necessary to form at equal intervals in the width direction.

4) Forming procedures of the plurality of reinforcing needle stitches 285a to 285c and 287a to 287c and the plurality of stitching needle stitches 285a to 285c and 287a to 287c are shown in FIGS. The present invention is not limited thereto, and the plurality of reinforcing needle stitches 285a to 285c and 287a to 287c and the plurality of stitching needle stitches 286a to 286c and 288a to 288c are formed in a continuous shape in a plurality of continuous loops. It is possible to do in the order of.
