Description

TECHNICAL FIELD The present invention relates to a method and an apparatus for manufacturing a shoulder pad attached to a shoulder of clothes.

[Conventional technology]

Conventionally, for example, as shown in FIG. 11, an upper cloth 20 and a lower cloth 2
A standard type shoulder pad 12 formed in a substantially semi-circular shape when viewed from above by stitching a plurality of layers of pad material 22 made of cotton material and a core 23 between them and It is known that the standard type shoulder pad 12 is formed and attached to the shoulder portion of the clothes 26 so that the line from the shoulder to the sleeved portion is arranged. That is, the upper standard type shoulder pad 12 is formed such that the central portion of the chord side end portion is thickened and gradually becomes thinner toward the arc side end portion, and the chord side end portion is formed in the armhole of the clothes 26. It is configured so that the line from the shoulder to the sleeved portion is linearly arranged by being mounted on the side, that is, on the outer end side of the shoulder portion.

And in recent years, as shown in FIG. 12, instead of the scare shoulder in which the line from the shoulder to the sleeved portion is linearly arranged, as shown in FIG. As shown in Fig. 13, a natural shoulder where the shoulder part continues in a natural shape,
Drop shoulders and the like in which the mounting portion of the sleeve 27 is located lower than usual are often used. Therefore, the chord side end (outer end) of the shoulder pad 12
To reduce the thickness of the above chord side end by manually removing the cotton of the pad material 22 located at, or to use a shoulder pad with the chord side end curved in advance to match the shoulder to sleeve line. This has made the line from the shoulder to the sleeve part rounded.

[Problems to be Solved by the Invention]

When the cotton that composes the pad material of the shoulder pad is manually extracted as described above, the work is complicated and it is difficult to set the amount of cotton to be extracted properly. There is a problem that left and right imbalance is likely to occur in the attachment line. Further, as described above, in the case where the end portion of the shoulder pad is configured to be curved in advance in accordance with the line from the shoulder to the sleeved portion, the production work of the shoulder pad becomes complicated, and mass production is difficult, Since the end part of the shoulder pad is curved, it is difficult to attach the shoulder pad, and it is difficult to properly set the protrusion amount of the string side end part that protrudes sideways from the armhole of the clothes. is there.

In order to prevent left-right imbalance in the sleeve attachment line, after attaching the shoulder pad from the shoulder of the clothes, the outer end of the shoulder pad protruding laterally from the armhole of the clothes is sheared. For example, it is possible to cut diagonally, but in this case, with the shoulder pad attached to the clothes, it is necessary to perform the diagonal cut using the sandwich, and the work is complicated, Since the cut line is easily bent, there is a problem that irregularities occur in the sleeve attachment line.

The present invention has been made in order to solve the above-mentioned problems, and the outer end portion of the shoulder pad can be cut off without requiring complicated work, whereby the shoulder to the sleeve attachment portion attached to the armhole can be cut off. An object of the present invention is to provide a method and apparatus for manufacturing a shoulder pad that can make a line round and can be properly and easily attached to a shoulder portion of clothes.

[Means for Solving the Problems]

And a guide plate 18 attached to the section. The guide plate 18 is made of a plate material whose upper portion is inclined in a direction away from the installation positions of the lower blade 3 and the upper blade 4, and when the standard pad 12 is cut, the upper end portion 19 of the standard pad 12, that is, the positioning member 5 is formed. The upper cloth 20 side portion located above the outer end side upper portion 13 locked by the restricting portion 11 is configured to be 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 a cloth material, a plurality of layers of a pad material 22 made of a cotton material and the like arranged between them, and the pad material. A core 23 disposed at a predetermined position inside 22;
They are formed into a substantially semi-circular shape when viewed from above by integrally joining them by means such as stitching or adhering. The standard pad 12 has the thickest central portion of the chord side end portion disposed on the outer end side of the clothes shoulder portion by changing the size and thickness of each pad material 22 in sequence, and the arc side end portion. It is formed so that the thickness becomes thinner as it reaches.

The standard pad 12 is manufactured by the shoulder pad manufacturing apparatus having the above structure.
A method of manufacturing the shoulder pad for cutting off the chord side end of the above will be described below. First, as shown by the phantom line in FIG. 2, after the guide member 6 is retracted upward, the chord side end portion, that is, the outer end portion, of the standard pad 12 in the reversed state is introduced below the guide member 6, and the end surface is positioned. The member 5 is brought into contact with the contact portion 10 and positioned. That is, the positioning member 5 is set so that the distance between the abutting portion 10 and the lower blade 3 corresponds to the horizontal cut amount l of the standard pad 12, and the abutting portion 10 has the standard pad 12 therebetween. The horizontal cut amount l of the standard pad 12 is set to an appropriate value by abutting the outer end surface thereof.

Further, the projecting position is preset so that the installation height of the restriction portion 11 corresponds to the cutting depth h of the standard pad 12, and the restriction portion 11 enters the pad material 22 of the standard pad 12. By locking the lower portion 13 on the outer end side thereof, the cut depth h of the standard pad 12 is regulated. Since the center pad 23 of the standard pad 12 is arranged in advance at a position corresponding to the cutting depth h, it should be positioned above the entry portion of the restricting portion 11 of the positioning member 5 in the above-described positioning state. Become.

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

The sewing machine is driven in the above state, and the standard pad 12 is automatically fed by the feed dog (not shown) of the sewing machine installed below the pressing portion 17, while the upper blade 4 is lowered to move the standard pad 12 side. The lower end portion 13 is sequentially cut off. That is,
While the standard pad 12 is sandwiched between the holding portion 17 of the guide member 6 and the feed dog of the sewing machine, the feed dog is driven to move the standard pad 12 stepwise, while the drive portion of the sewing machine is moved. The cutter shaft 8 is moved up and down to raise and lower the upper blade 4, and when the upper blade 4 descends, the lower blade 3 and the upper blade 4 cut out the lower portion 13 on the outer end side of the standard pad 12 to cut it. To do. The cut chips fall into the chip discharge hole 2 and are discharged to the outside through a discharge duct (not shown).

Is attached to the shoulder of the clothes 26. Since the shoulder pad 25 has the thickness of the chord side end portion reduced by forming the notch 24, the clothes 26
By rounding the line from the shoulder to the attachment portion of the sleeve 27 sewn to the armhole, the shoulder portion of the clothes 26 and the sleeve 27 can be connected in a natural shape.

In this way, the contact portion 10 of the positioning member 5 and the restriction portion 1
Since the outer edge side lower portion 13 of the standard pad 12 is cut off by the upper blade 4 and the lower blade 3 in a state in which the horizontal cutting amount 1 and the cutting depth h of the cutout 24 are set to proper values by 1, the predetermined value is set. It is possible to easily and uniformly form the notches 24 having a size of. Therefore, it is possible to effectively prevent the left and right imbalances from occurring in the line of the sleeve attachment portion due to the variation in the size of the cut 24. In addition, the setting position of the positioning member 5 is adjusted within the range of the elongated hole 14, or the regulating portion 1
The horizontal cut amount 1 and the cut depth h of the shoulder pad 25 can be easily changed by replacing it with another positioning member having a different installation height.

In addition, since the guide plate 18 of the guide member 6 of the outer end side upper portion 19 of the standard pad 12 is configured to retreat laterally, the upper blade 4 is lowered without being obstructed by the outer end side upper portion 19. The lower part 13 of the standard pad 12 on the outer end side can be cut off. Further, in the above-described embodiment, since the center pad 23 of the standard pad 12 is arranged at the position corresponding to the cutting depth h, depending on the position of the center core 23, the regulating portion 11 of the positioning member 5 engages. The outer end side lower portion 13 to be stopped and the outer end side upper portion 19 which is retracted laterally by the guide plate 18 are easily separated, and the standard pad 12 is provided.
Can be installed on the workbench 1 in an appropriate state.

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 cutting operation is automated by using the drive portion of the sewing machine. In this case, there is an advantage that the cutting operation can be performed quickly and easily.

For example, as shown in FIG. 5, a positioning member having a restricting portion 28 having a triangular cross section on which the outer end portion of the standard pad 12 is placed and an abutting portion 29 projecting obliquely upward from the base end portion thereof. 5, the outer end surface of the standard pad 12 is brought into contact with the abutting portion 29 to set the horizontal cut amount l, and the regulating portion 2 is provided.
By mounting the outer end portion of the standard pad 12 on 8 and inclining the outer end portion side lower portion 13, the outer end side lower portion 1
The cutting angle of the upper blade 4 with respect to 3 may be regulated. By doing so, as shown in FIG. 6, it is possible to form the shoulder pad 25 provided with the trapezoidal notch 24 in which the end face 24b is inclined at a predetermined angle. The case where the notch 24 is formed on the upper cloth 20 side of the chord side end of the shoulder pad 25 by installing 12 on the workbench 1 in the inverted state has been described, but the back surface of the standard pad 12 faces downward. As shown in FIG. 7, the cutting length is set to 1 and the cutting depth is set to h on the lower cloth 21 side of the chord side end of the shoulder pad 24 by installing it on the workbench 1 in this state. The cutout 24 having a rectangular cross section may be formed, or as shown in FIG. 8, the cutout 24 having a trapezoidal cross section may be formed on the lower cloth 21 side of the chord end of the shoulder pad 25. .

Further, as shown in FIG. 9, after forming a first notch 24α having a notch depth h1 at the chord side end portion of the standard pad 12, as shown in FIG. By forming the second cut 24β having the cut depth h2, the shoulder pad 25 in which the thickness of the chord side end portion is gradually reduced
Can also be formed. In this case, it is desirable to dispose the cores 23 at positions corresponding to the cut depths h1 and h2 of the first and second cuts 24α and 24β, respectively.
