Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for manufacturing shoulder pads that are attached to the shoulders of clothes.

[Conventional technology]

Conventionally, for example, as shown in FIG. 11, an upper cloth 20 and a lower cloth 2
1, a plurality of layers of pa-sodo material 22 made of cotton material,
A standard type shoulder pad 12 having a substantially semicircular shape when viewed from above is formed by suturing with the center core 23 interposed therebetween, and this standard type shoulder pad 12 is attached to the shoulder portion of clothes 26. It is known that the line from the shoulders to the sleeves is adjusted. That is, the standard type shoulder nod 12 is formed to be thick at the center of the string-side end, and gradually become thinner as it reaches the arc-side end, so that the string-side end is connected to the armhole of clothes 26. By attaching it to the side, that is, on the outer end side of the shoulder, the line from the shoulder to the sleeve is arranged in a straight line.

In recent years, in place of the square shoulder design in which the line from the shoulder to the sleeve is arranged in a straight line as described above, as shown in FIG. A natural shoulder where the shoulder part is naturally continuous, as shown in Figure 13,
For mounting the sleeve 27, a drop shoulder style, in which the sleeve part is positioned lower than usual, is often used.

For this reason, the cotton of the pad material 22 located at the string side end (outer end) of the shoulder pad 12 is manually removed to reduce the thickness of the string side end, or the thickness of the pad material 22 is reduced from the shoulder to the sleeve in advance. By using a shoulder pad with a curved end on the string side to match the line, the line from the shoulder to the sleeve is rounded.

[Problem to be solved by the invention]

If the cotton that makes up the padding material of the shoulder pads is manually removed as described above, the work is complicated and it is difficult to set the appropriate amount of cotton to remove. There is a problem with sleeve attachments that the line of the sleeve tends to be unbalanced from left to right.

Furthermore, if the ends of the shoulder pads are configured to be curved in advance to match the line of the shoulder to sleeve section as described above, the manufacturing work of the shoulder pads becomes complicated and mass production is difficult. Because the ends of the shoulder pads are curved, it is difficult to attach the shoulder pads, and it is also difficult to properly set the amount of protrusion of the string-side ends that protrude laterally from the armholes of clothing. There is.

In addition, in order to prevent left and right imbalances in the sleeve part lines, after attaching the shoulder pads to the shoulders of the clothes, cut the outer ends of the shoulder pads that protrude sideways from the armholes of the clothes with scissors. It is also possible to cut the shoulder pad diagonally, but in this case, it is necessary to make the diagonal cut using a pair of scissors while the shoulder pad is attached to the clothes, which makes the work complicated. Because the cut line is easy to bend, there are problems with sleeve attachment, such as unevenness in the part line.

The present invention was made in order to solve the above problems, and the outer end of the shoulder pad can be cut off without any complicated work, thereby making it possible to cut off the outer end of the shoulder pad that is attached to the armhole. It is an object of the present invention to provide a method and apparatus for manufacturing a shoulder pad that can have rounded lines and that can be properly and easily attached to the shoulders of clothes.

[Means to solve the problem]

The method for manufacturing a shoulder pad according to the invention according to claim 1 is to form a standard pad by interposing an appropriate pad material between an upper cloth and a lower cloth, and then place the outer end surface of this standard pad on a workbench. By bringing the standard pad into contact with the contact part of the installed positioning member, the outer end of the standard pad is positioned with respect to the lower blade disposed below it, and the lower part of the outer end of the standard pad is positioned. With the standard pad locked by the cutting depth regulating part and the upper part of the outer end of the standard pad retracted laterally by the guide member, the upper blade is lowered to cut the lower part of the outer end of the standard pad. The upper and lower blades are used to cut the area.

The shoulder pad manufacturing apparatus according to the invention according to claim 2 includes a lower blade fixed to a workbench, an upper blade installed at a position facing the lower blade so as to be able to rise and fall freely, and the upper blade and the lower blade. It has a positioning member that positions the lower outer end of the standard pad to be removed, and a guide member that retracts the upper outer end of the standard pad to its inner side. It is provided with an abutting part that the end surface abuts, and a regulating part that locks the lower part of the outer end of the standard pad and regulates the depth of the cut.

[For production]

According to the present invention having the above configuration, by installing the standard pad on the workbench and bringing the outer end of the standard pad into contact with the abutting part of the positioning member, the standard pad to be cut by the lower blade and the upper blade can be cut by the lower blade and the upper blade. The horizontal cutting length is set to an appropriate value, and the lower portion of the outer end of the standard pad is locked by the regulating portion of the positioning member, so that the cutting depth is regulated to an appropriate value. In addition, by retracting the upper part of the outer end side of the standard pad to the side by the guide member, the upper blade can be lowered to move the lower part of the outer end side of the standard pad without being obstructed by the upper part of the outer end side. can be excised.

It is configured to be driven up and down together with the needle bar.

The positioning member 5 includes a mounting portion 9 screwed onto the workbench 1 at the front portion of the discharge hole 2, an abutment portion 10 extending downward from the tip thereof, and a protruding portion from the upper end thereof. As will be described later, the outer end lower part 13 of the standard pad 12, that is, the part on the upper cloth 20 side of the string side end, is positioned by the abutting part 10, as will be described later. The horizontal cutting depth is set to l, and the regulating portion 11 locks the lower outer end portion 13 to regulate the cutting depth to h. Also,
The positioning member 5 is attached to a long hole 1 formed in the portion 9.
It is attached to the workbench 1 by screws 15 that pass through 4,
By sliding this screw 15 on the workbench 1 in a loosened state, its installation position can be changed within the range of the elongated hole 14, thereby creating a cut in the lower part 13 of the outer end side of the standard pad 12. It is configured to adjust the horizontal depth of cut l.

The guide member 6 also includes a presser foot 17 that is attached to a presser bar 16 of the sewing machine, and that descends when cutting into the standard pad 12 to press the upper surface of the lower outer end portion 13 of the standard pad 12, and its sides. It has a guide plate 18 attached to the section. This guide plate 18 is made of a plate material whose upper part is inclined in the direction away from the installation position of the lower blade 3 and the upper blade 4, and when cutting the standard pad 12, the outer end side upper part 19, that is, the positioning member 5 is It is configured such that a portion on the upper cloth 20 side located above the outer end side upper portion 13 locked by the regulating portion 11 is retracted to the inner side portion of the standard pad 12.

As shown in FIG. 3, the standard pad 12 includes an upper cloth 20 and a lower cloth 21 made of cloth or the like, a plurality of layers of padding material 22 made of cotton or the like disposed between them, and this padding material. a core 23 disposed at a predetermined position inside the core 22;
These are joined together by means such as suturing or adhesion to form a substantially semicircular shape when viewed from above. By sequentially changing the size and thickness of each pad material 22, the standard pad 12 is thickest at the center of the string-side end disposed on the outer end of the shoulder of the clothes, and thickest at the arc-side end. It is formed so that the thickness becomes thinner as it reaches .

Standard pad 12 is manufactured by the shoulder pad manufacturing apparatus having the above configuration.
A method of manufacturing a shoulder pad by cutting off the string-side end of the shoulder pad will be described below. First, as shown by the imaginary line in FIG. 2, after retracting the guide member 6 upward, the string-side end, that is, the outer end, of the standard pad 12 in an inverted state is introduced below.
The end face thereof is brought into contact with the contact portion 10 of the positioning member 5 for positioning. That is, the positioning member 5 is set so that the distance between the contact portion 10 and the lower blade 3 corresponds to the horizontal cutting amount l of the standard pad 12, and the standard pad 12 is attached to the contact portion 10. By bringing the outer end surfaces of the standard pad 12 into contact with each other, the horizontal cutting amount l of the standard pad 12 becomes an appropriate value and the standard pad 12 is positioned.

Further, the protruding position is set in advance so that the installation height of the regulating part 11 corresponds to the cutting depth h of the standard pad 12, and the regulating part 11 is inserted into the pad material 22 of the standard pad 12. By locking the lower outer end portion 13 of the standard pad 12, the cutting depth h of the standard pad 12 is regulated. In addition, since the center core 23 of the standard pad 12 is previously arranged at a position corresponding to the cutting depth h, it is located above the entry point of the regulating part 11 of the positioning member 5 in the above positioning state. Become.

Next, while holding the upper outer end portion 19 of the standard pad 12 by hand and displacing it toward the inner side of the standard pad 12, the guide member 6 is lowered as shown by the solid line in FIG.
7 is brought into contact with the upper surface of the lower outer end portion 13 to press it downward. Thereafter, when the hand holding the standard pad 12 is released, the upper outer end portion 19 comes into contact with the guide plate 18 and is held in a laterally retracted state.

In the above state, the sewing machine is driven, and while the standard pad 12 is automatically fed by the feed dog (not shown) of the sewing machine installed below the presser foot 17, the upper blade 4 is lowered to the side of the standard pad 12. The lower end portions 13 are sequentially removed. That is,
With the standard pad 12 being held between the presser part 17 of the guide member 6 and the feed dog of the sewing machine, by driving the feed dog, the standard pad 12 is advanced in stages while the drive part of the sewing machine The cutter shaft 8 is moved up and down through the upper blade 4 to raise and lower the upper blade 4, and when the upper blade 4 is lowered, the lower blade 3
and the upper blade 4, the outer end side lower part 13 of the standard pad 12 is
Cut it out by cutting it off.

The cut chips fall into the chip discharge hole 2 and are discharged to the outside via a discharge duct (not shown) or the like.

By cutting out the entire length of the lower outer end portion 13 of the standard pad 12 as described above, the amount of horizontal cut can be made as shown in FIG. A shoulder pad 25 is formed having a notch 24 having a rectangular cross section and a depth of h.
It is attached to the shoulder part of the clothes 26 based on . The thickness of the shoulder pad 25 at the end of the shoulder pad 25 is reduced in some cases due to the formation of the notch 24, so that it can be used for clothes 2.
The sleeve 27 is sewn from the shoulder of the garment 26 to the armhole, and the line from the shoulder to the armhole is rounded, so that the shoulder of the garment 26 and the sleeve 27 can be connected in a natural manner.

In this way, the abutting part 10 and the regulating part 1 of the positioning member 5
1 is the horizontal cutting amount of the above cutting depth 24! Since the lower part 13 of the outer end side of the standard pad 12 is cut by the upper blade 4 and the lower blade 3 while the cutting depth h is set to an appropriate value, a cut 24 of a predetermined size can be easily and uniformly cut. can be formed into Therefore, it is possible to effectively prevent a left-right imbalance in the line of the armhole due to variations in the size of the cuts 24. Further, the installation position of the positioning member 5 may be adjusted within the range of the elongated hole 14, or the regulating portion 1 may be adjusted.
By replacing the positioning member 1 with another positioning member with a different installation height, the horizontal cutting amount of the shoulder pad 25 can be changed! and the depth of cut h can be easily changed.

Furthermore, since the upper outer end portion 19 of the standard pad 12 is configured to be retracted laterally by the guide plate 18 of the guide member 6, the upper blade 4 can be lowered without being obstructed by the upper outer end portion 19. lower part 1 on the outer end side of the standard pad 12
3 can be removed. Further, in the above embodiment, since the center core 23 of the standard pad 12 is arranged at a position corresponding to the cutting depth h, the regulating portion 11 of the positioning member 5 is adjusted according to the position of the center core 23. The lower outer end portion 13, which is locked by the guide plate 18, and the upper outer end portion 19, which is retracted laterally by the guide plate 18, are easily separated, and the standard pad 12 is placed on the workbench 1 in an appropriate state. The advantage is that it can be done.

Further, as in the above embodiment, the upper blade 4 is attached to the cutter shaft 8 of the sewing machine, the guide member 6 is attached to the presser bar 16 of the sewing machine, and the above-mentioned cutting operation is automated using the drive section of the sewing machine. In this case, there is an advantage that this cutting operation can be performed quickly and easily. Note that the shoulder pad manufacturing method and manufacturing apparatus according to the present invention does not necessarily need to perform automatic cutting and automatic feeding using the drive unit of the automatic thread trimming sewing machine with a knife, but can raise and lower the upper blade 4 by manual operation. Alternatively, the standard pad 12 placed on the workbench 1 may be manually advanced.

Further, in the above embodiment, the outer end side lower part 1 of the standard pad 12 is
Although the case where the notch 24 having a rectangular cross section is formed in the cutout 3 has been described, the shape of the notch 24 is not limited to the above embodiment and can be modified in various ways. For example, as shown in FIG. 5, a regulating part 28 having a triangular cross section on which the outer end of the standard pad 12 is placed, and an abutting part 29 projecting obliquely upward from the base end thereof are connected to each other by a positioning member. 5, the outer end surface of the standard pad 12 is brought into contact with the abutting part 29 to set the horizontal cutting amount l, and the regulating part 28
By placing the outer end portion of the standard pad 12 on top and tilting the outer end side lower portion 13, this outer end side lower portion 13
The cutting angle of the upper blade 4 relative to the cutting angle may be regulated. In this way, as shown in FIG. 6, it is possible to form a shoulder pad 25 having a trapezoidal notch 24 formed by inclining the end surface 24b at a predetermined angle.

-15= Furthermore, in the above embodiment, the notch 24 is formed on the upper cloth 20 side at the end of several examples of the shoulder pad 25 by installing the standard pad 12 upside down on the workbench 1. However, by installing the standard pad 12 on the workbench 1 with the back surface facing downward, as shown in FIG. The length! A notch 24 having a rectangular cross section and a cutting depth set to h is formed, or, as shown in FIG. It may be formed as follows.

Furthermore, as shown in FIG. 9, after forming a first cut 24α with a cutting depth hl at the end of several examples of the standard pad 12, as shown in FIG. By forming the second cut 24β with the cut depth h2, the thickness of the end portion of the shoulder pad 25 is gradually reduced in some cases.
can also be formed. In this case, the above 1. It is desirable that the center cores 23 are disposed at positions corresponding to the cutting depths hl and h2 of the second cuts 24α and 24β, respectively.

〔Effect of the invention〕

As explained above, the present invention allows cuts of a predetermined size to be formed accurately and uniformly on the outer edge of a standard pad, so that the sleeve attachment can be made naturally without causing left-right imbalance or unevenness in the part line. There is an advantage that the shoulder pad that forms the line of the rounded shoulder to sleeve part, such as shoulder and drop shoulders, can be easily formed.
