Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a button sewing machine, and more particularly to a control device for a button sewing machine for a gentleman's body and a female body.

[Conventional technology]

FIG. 5 shows a state in which a cloth, for example, a men's body, is attached to a conventional button sewing machine, 1 is a button-attached sewing machine main body, 2 is a button feeder, 3 is a right side cloth set plate, 4
Is a left side fabric set plate, 5 is a fabric, 6 is a positioning gauge for the fabric 5 on the left side fabric set plate 4, 7 is a reciprocating fabric transport table, 8 is a clamping means for the fabric 5 with respect to the transport table 7, 8a Reference numerals 8b are the clamp elements.

In such a conventional button sewing machine, when a button is attached to the cloth 5, for example, a men's body, as shown in FIG. 5, the men's body is placed on the cloth conveying table 7, and the side on the button side is attached. Left and right fabric set plates
The upper end of the men's body is positioned on the cloth conveying table 7 by the positioning gauge 6 on the left cloth setting plate 4, and the start button (not shown) is pressed to clamp one side of the clamping means 8. The men's body is temporarily fixed by the element 8a, and in this state, the entire side on the button attachment side is reworked so as to be properly contacted with the left and right fabric set plates 4 and 3.

Next, when the start button is released, the other clamp element 8b of the clamp means 8 completely clamps the men's body,
At this position, the button sewing machine main body 1 starts the button attaching work, and the buttons (not shown) supplied from the button feeder 2 are sewn on the body of the gentleman.

When sewing of one button is completed, the cloth transport table 7
The body of the sewing machine with buttons is automatically attached by the sewing machine body 1
5 is moved by a predetermined distance in the direction of the arrow in FIG. 5, and the button sewing work similar to the above is performed, and all the buttons from the upper end to the lower end of the men's body are repeated by repeating such a process. When the sewing is finished, the men's body is discharged to the storage section and the button attaching work is completed.

When attaching a button to the body of a woman, place the body of the woman on the cloth conveying table 7 as shown in FIG. 6, and contact the sides of the button with the left and right cloth set plates 4 and 3, After positioning the lower end of the female body by the positioning gauge 6 on the left cloth setting plate 4 on the fabric conveying table 7, press the start button and temporarily clamp the female body by the clamp element 8a of the kun lamp means 8, and press the button. After the entire sides of the attachment side have been properly brought into contact with the left and right fabric set plates 4 and 3, the same sewing work as in the case of the men's body is performed.

[Problems to be Solved by the Invention]

As described above, in the conventional button sewing machine, when the button is sewn on the female body, the female body to which the button is sewn is on the opposite side of that of the men's body. When the button sewing machine shown in the figure is used as it is, the buttons are sequentially sewn from the lower end to the upper end of the body.

In such a case, it is not preferable because an error in the button attachment position due to the influence of sewing, especially shrinkage of the fabric after the perforation, appears largely at the upper end of the body which is easily noticed by the human eye.

The present invention eliminates such drawbacks.

[Means for solving the problem]

A button sewing machine control device of the present invention includes a button sewing machine main body, a button feeder, right and left cloth setting plates, and a reciprocating cloth conveying table to sew a plurality of buttons to a body at predetermined intervals. In a possible sewing machine with buttons, a switch for setting whether the body to be sewn is a body for a gentleman or a body for a woman, and a control means for switching the transport direction of the cloth transport table by the setting of this switch The women's body is also characterized by sewing from the upper end of the body.

[Work]

In the control device for a button sewing machine of the present invention, the buttons to be sewn on are sequentially performed from the upper end of the body of both men and women, so that the buttoning position of the upper end becomes accurate.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, a female positioning gauge 6'is provided on the right side fabric set plate 3, and
As shown in FIG. 2, the operation box A is provided with a switch B for setting whether the body to which the button is sewn is a body for a gentleman or a body for a woman. Further, the first to third switches 9 are arranged from the left to the right on a fixed plate (not shown), which are sequentially spaced apart in the moving direction at a position corresponding to the intermediate portion of the moving stroke of the cloth conveying table 7. ~ 11 and the first of these three
~ Left detection of a predetermined length provided at the left end of the cloth transport table 7 so that the two first and second switches 9 and 10 from the left of the third switches 9 to 11 can be turned on Board 12
And an origin discriminating means 14 composed of a right side detection plate 13 of a predetermined length provided at the lower right end of the cloth transport table 7 so that all of the first to third switches 9 to 11 can be turned on. Set up.

The left side detection plate 12 and the right side detection plate 13 are arranged such that when the cloth transport table 7 moves to the right in FIG. When the switches 9 and 10 are turned on, but the right side detection plate 13 does not turn on any of the first to third switches 9 to 11, and the cloth transport table 7 is moved to the leftmost position in FIG. As shown in FIG. 4, the left side detection plate 12 does not turn on any of the first to third switches 9 to 11, but the right side detection plate 13 does not turn on.
Set the length and layout so that all the switches 9 to 11 can be turned on. Next, the operation will be described. When the power switch (not shown) is turned on after setting the body for men's or the body for women with the switch B, the CPU (not shown) reads the setting of the switch B, and the gentleman who has set the cloth transport table 7 It is determined whether or not it is at the origin position of the body or lady's body, and if it is not at the origin position, it moves to the origin position and waits in a state where button work is possible. That is, in the case where the switch B is set to the body for a gentleman, when only the first and second switches 9 and 10 are turned on by the left side detection plate 12 in the origin determining means 14, the button sewing machine is operated by the CPU. When it is determined that the men's body is at the origin position, the buttoning work of the men's body is started, and when the switch B is set to the women's body, the origin discriminating means 14 uses the right side detection plate 13 to determine the first to When all the third switches are turned on, it is determined that the button sewing machine is located at the origin of the woman, and the button attaching work for the body of the woman is started.

Next, the body is placed on the cloth conveying table 7, the start button is pressed and the body is temporarily fixed by one clamp element 8a. Then, when the start button is released, the other clamp element 8b is clamped and the CPU of the switch B By the control means that switches the transport direction of the fabric transport table by setting,
The feeding direction is reversed between the gentleman's body and the ladies' body, and a predetermined length is sequentially stopped from the upper end of each body to the lower end, and a plurality of button attaching operations are sequentially performed.

〔The invention's effect〕

Since the control device for the button sewing machine of the present invention has the above-mentioned configuration, the movement direction of the cloth transport table is changed between the men's body and the woman's body, and a plurality of bodies are formed at predetermined intervals from the upper end to the lower end of the body. Since the buttoning can be performed, the buttoning position error due to the influence of shrinkage of the cloth does not occur at the upper end of the body which is easily noticed by human eyes.
