Description

  The present invention sews a shoulder yoke cloth on the front part or the back body which is a constituent part of a shirt or the like, or a back part or a front part corresponding to the shoulder yoke cloth sewn on the front part or the back part. The present invention relates to a shoulder yoke cloth sewing device and a sewing method for clothing to be worn.

  Conventionally, in a shirt or the like, a shoulder yoke cloth is sewn on the front part or the back part, which is a component part thereof, or a back part or a front part corresponding to the shoulder yoke cloth sewn on the front part or the back part is sewn. For example, as shown in Patent Document 1, the outer yoke cloth and the front body or the back body and the inner yoke cloth are placed so as to be adjacent to each other, and the front body or the back body is inverted and folded, and between the folded portions. After inserting the heat-adhesive strip, flip the inner yoke cloth so that it overlaps itself, fold it, sew the folded part of the outer yoke cloth, the heat-adhesive strip, the outer yoke, the front or back and the inner yoke cloth. There is known a method for sewing a shoulder yoke cloth in which an outer yoke cloth is joined by a heat-adhesive strip that is melted by hot-pressing a stitched portion after being worn.

However, the method of sewing the shoulder yoke cloth shown in Patent Document 1 is the work of turning the inner yoke cloth and the outer yoke cloth inwardly and turning them back inward, or between the folded inner edges of the folded inner yoke cloth and outer yoke cloth. Alternatively, since the operation of sewing with the back of the body sandwiched is performed manually, it takes time and effort to perform these operations, resulting in poor sewing work efficiency.

In addition, in order to overlap the inner yoke cloth and the outer yoke cloth as described above, or to insert and overlap the front and back edges between the inner yoke cloth and the outer yoke cloth, the edges of the inner yoke cloth and the outer yoke cloth are overlapped in a short time. Must be aligned and overlapped so that they match each other, requiring a high level of skill for the operator, and also having the problem of poor productivity.

Furthermore, in order to sew the front or back body between the inner yoke cloth and the outer yoke cloth folded inward, the inner yoke cloth and the outer yoke cloth, the front body and the back body, etc. It is necessary to prepare various processing tools such as clothing component parts, irons, and heat-adhesive strips side by side, which causes a problem that workability in the work table is narrowed and workability is deteriorated.

The front and rear moving members 61 are driven to move closer to each other, and the knob 55 and the folding member 63 are moved to the front of the sewing line SL with respect to the traveling frame 35.

Further, at the timing synchronized with the above operation or the timing at which the knob member 55 and the folding member 63 move forward from the sewing line SL, the fourth longitudinally moving member 67 and the third vertically moving member 71 are operated so that the respective rods extend. Then, the folding member 63 is separated from the knob member 55 and is swung so as to be positioned at the upper front position.

Next, the outer shoulder yoke cloth 77 folded back in the above state is folded forward and set so as to be flat on the ruler plate 9, and the inner shoulder yoke cloth is folded rearward. 79. (See Figure 8)

Next, the first vertical movement member 45 is operated in the direction in which the rod extends to move the pressing body 41 downward, and the inner shoulder yoke cloth 79 whose front end edge is folded backward at the rear position from the sewing line SL; In a state in which the outer shoulder yoke cloth 77 folded back into a flat shape is pressed and the positional deviation is restricted, the third longitudinally moving member 61 is driven in the reverse direction so that the knob member 55 moves in a direction approaching the pressing body 41 and the pressing body. 41, a part of the front end edge of the outer shoulder yoke cloth 77 is clamped. (See Figure 9)

Next, in the above state, the first vertical movement member 45 is operated in the direction in which the rod is contracted to move the folding overlap means 22 upward, and the first longitudinal movement member 21 is operated in the direction in which the rod is contracted. The folding overlapping means 22 is moved rearward to open the space around the ruler plate 9 and secure a working space. In addition, the fourth longitudinally moving member 67 and the third vertically moving member 71 are actuated in the direction in which the respective rods are contracted at the timing parallel to the above operation or after the above operation, and the folding member 63 is swung in the direction close to the knob member 55. When moved, the front end edge of the outer shoulder yoke cloth 77 that hangs downward by the folding plate 65 entering the lower surface side of the pressing body 41 and the knob member 55 is folded and held inward. In this state, the front body 81 is set to overlap with the folded end of the inner shoulder yoke cloth 79 adsorbed and held on the work table 4 so that the shoulder side ends thereof coincide with each other. (See Figure 10)

Next, the first longitudinally moving member 21 is operated in the direction in which the rod extends, and the front end of the pressing body 41 of the folding and overlapping means 22 moves forward toward the sewing line SL and the rod moves the first vertically moving member 45. The front folded portion of the inner shoulder yoke cloth 79 is superposed on the front folded portion of the outer shoulder yoke cloth 77 which is operated in the extending direction and is held by the pressing body 41, the gripping member 55 and the folded member 63 of the folded overlapping means 22. Overlap the edge of 81.

The folding member 63 is separated from the knob member 55 by operating the fourth longitudinally moving member 67 and the third vertically moving member 71 in the direction in which the respective rods extend in a timing parallel to the above operation or a timing after the above operation. Then, the folded plate 65 is extracted from between the folded edge of the outer shoulder yoke cloth 77 which is swung so as to be positioned at the upper position on the front side and the front body 81 and separated. (See Figure 11)

After the above operation, the fourth longitudinally moving member 67 and the third vertically moving member 71 are actuated in the direction in which the respective rods are contracted to swing so that the folding member 63 comes close to the knob member 55, 3. The longitudinally moving member 61 is driven to move the knob member 55 and the folding member 63 rearward from the sewing line SL. Also, the outer shoulder yoke overlapped by operating the second longitudinally moving member 51 in the direction in which the rod contracts at the timing parallel to the above operation or the timing after the above operation to move the clamping body 49 to the pressing body 41 side. After the cloth 77 and the inner shoulder yoke cloth 79 are clamped and held in cooperation with the pressing body 41, the negative pressure suction of the inner shoulder yoke cloth 79 and the back body 75 by the suction hole 4a and the opening 4b is released. (See Figure 12)

After the above operation, the holding by the lowered pressing body 41 and the suction by the suction hole 3a in the state of being held by the pressing body 41 and the holding body 49 that are close to each other are released, and then the electric motor 39 is driven and superposed. The sewing machine 5 is driven while the front edge of the front body 81, the outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79 are moved along the sewing line SL, and a predetermined amount is required from the folded end of the outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79.

A cloth detector (not shown) incorporating a light emitting member and a light receiving member is provided in front of the needle position of the sewing machine 5, and a reflective tape (not shown) is provided on the work table 4 facing the cloth detector. ) And the cloth detector controls to stop sewing when the cloth is not detected, while driving the sewing machine 5 so as to sew when the cloth is detected.

When the front end edge of the front body 81, the outer shoulder yoke cloth 77, and the inner shoulder yoke cloth 79 are moved to the left in the drawing of the work table 4 as the sewing progresses, the pressing body 41 against the upper surface of the work table 4 is moved. Is gradually released, and the holding of the front end edge of the front body 81 and the outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79 is released, but the holding state is continued by the clamping by the pressing body 41 and the clamping body 49.

When the folding overlap means 22 is moved above the stack bar 73 at the end of sewing on the front edge of the front body 81 and the outer shoulder yoke cloth 77 and inner shoulder yoke cloth 79, the rod extends the second longitudinally moving member 51. The outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79 are released from the pressing body 41 and the holding body 49, and are dropped onto the stack bar 73 and accumulated.

In this embodiment, when the outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79 sewn on the back body 75 are set on the work table 4, the folding overlap means 22 is detached from the main body tape 3. By moving to the position and waiting, the work area can be widened, and the set work can be performed efficiently.

Further, when the front end edge of the front body 81 is overlaid on the folded edge of the folded inner shoulder yoke cloth 79, the working area can be widened by moving the folding overlapping means 22 backward and waiting. It is possible to perform the matching work efficiently.

Furthermore, the front edge of the inner shoulder yoke cloth 79 and the outer shoulder yoke cloth 77 is folded back inward and the front or back edge of the body sandwiched between the two is automatically sewn, requiring a high level of skill. Therefore, the work of sewing the shoulder yoke cloth can be performed efficiently, and the productivity of the clothes can be improved.

In the above description, the front edge of the overlapped front yoke cloth 77 and inner shoulder yoke cloth 79 sewn in a folded state with a desired width on the front and back of the shoulder edge of the back body 75 are folded inward with a desired width to the front body. 81, the shoulder edges of the back body 75 are sewn by folding the rear end edges of the outer shoulder yoke cloth 77 and the inner shoulder yoke cloth 79 inward with a desired width. Even if it is, it can be implemented.
