The bite member 12 is composed of left and right arms 15 and 15 provided with a pair of left and right bite plates 13, 13 and 14, 14, and a pair of left and right bite plates is arms 15 and 15. The opening and closing operations of the carrier 11 allow the carriers 11 to reciprocally rotate so as to open along the circumferential orbit of the carrier 11 and the upper and lower bite plate pairs can be pressed and separated from each other.

The biting member 12 is moved in the clockwise direction (arrow direction) in FIG. 4 by the movement of the carrier 11 along the circumferential orbit line.
Work station I installed on the circular orbit line
Through VI.

The first work station I comprises a bite member 1
It is the apparatus position of the materials S ₁ and S 2 with respect to ₂ , and the materials S ₁ and S ₂ are manually attached to the upper bite plate pairs 13 and 13 and the lower bite plate pairs 14 and 14, respectively.

Then, while the bite member 12 to which the materials S ₁ and S ₂ are attached moves from the second work station II to the third work station III, first an appropriate positioning device 16 (for example, Japanese Patent Publication No. No. -47234), the waist band 1 of the materials S ₁ and S ₂ attached to the upper and lower biting plate pairs 13, 13 and 14, 14 and the garter line (or Langard line) that becomes the boundary line between the panty portion 2 and the leg portion 3. ) 5 is positioned at a predetermined position on each pair of bite plates so as to be aligned with the upper and lower sides, and after positioning, the pair of upper and lower bite plates, which have been separated so far, are pressed against each other to form the materials S ₁ , S ₂ And the cutting member 17 at the third work station III.
The inner crotch portion of the panty portion 2 is cut by the above, and the pair of left and right bite plates are expanded from the parallel state to the circumferential orbit line until reaching the fourth work station IV, and the materials S ₁ and S in the overlapped bite state are opened. ₂
The inner crotch cutting edge of is exposed to the outside.

Next, while the bite member 12 is moved from the fifth work station V to the sixth work station VI in the expanded state, the inner crotch portion cutting edges of the exposed materials S ₁ and S ₂ are removed. When the sewing machine 18 is sewn and the bite member 12 further moves to the sixth work station VI, the pressed state of the bite member is released and the material after sewing is taken out,
The pair of left and right bite plates of the bite member returns from the expanded state to the original parallel state and moves to the first work station I again.

As described above, when the pantyhose is sewn using the pair of materials S ₁ and S ₂ , both materials S ₁ and S ₂ are respectively placed on the upper and lower bite plates of the bite member as the first preparatory work. It must be mounted, but this mounting work is performed manually by the worker.

The conventional materials S ₁ and S ₂ shown in FIG.
In that case, since the entire circumference of the panty portion 2 is formed by the same knitting structure, the operator simply attaches the pair of materials S ₁ and S ₂ to the pair of upper and lower bite plates and the width direction ( It is possible to perform the work without paying attention to the directionality in the (circumferential direction), and the mounting work can be performed easily and quickly.

By the way, in recent years, panty hose are high-class product oriented products by supporting to cope with changes in yarn usage and zocchi, and high value-added products by differentiation to cope with changes in knitting structure, and composite products of these products. Production has become particularly prominent these days.

8 and 10 show examples of those products. That is, FIG. 8 shows a three-dimensional panty hose 20 with a bulge in the hip portion at the knitting stage, and the material S
C ₁ and SC ₂ (see FIG. 7) are formed from the waist band 1, the panty portion 2, the leg portion 3 and the toe portion 4 similarly to the conventional materials S ₁ and S _2, and the panty portion 2 thereof. Is different from the conventional one, it is composed of a front part 22 of mesh knitting and a hip part 23 of plain knitting through a boundary line 21, and the hip part 23 has a three-dimensional knitting shape having a bulge.

Correct position and panty section 2
It is necessary to dispose a predetermined portion of the above at a predetermined position on the bite plate pair.

That is, one of the materials SC ₁ and SC ₂ has a boundary line 21, and the other materials SB ₁ and SB ₂ have marks 31 and 32.
By matching up and down at the positions on the center line of the pair of left and right bite plates, cutting the matching portions, and sewing, to obtain the pantyhose 20 and 30 shown in FIGS. 8 and 10. If these boundaries 2
1. If the marks 31 and 32 are displaced from the positions on the center line of the pair of left and right bite plates, or do not match up and down, the left and right knitting structures of the panty portion 2 around the stitch 6 are symmetrical. However, either the left side or the right side is shifted to one side, which has no commercial value as panty hose, and causes defective products.

Therefore, in the materials SC ₁ and SC ₂ , as shown in FIG. 11, the panty portion 2 of _one material SC ₁ mounted between the upper bite plate pairs 13 in a tensioned state is The boundary line 21 is arranged at a position on the center line between the bite plate pairs 13, 13 and the lower bite plate pair 14, 14

[0021]

However, the above-mentioned mounting work accompanied by the work for correcting the position of the material in the width direction occurs between the material mounted in a tension state and both side surfaces of the pair of left and right bite plates. Due to the large friction resistance, the work requires a long time and the work efficiency is extremely poor, which is a factor that greatly deteriorates the performance of the crotch sewing machine.

Further, if the material used for threading is a material having a strong tightening force (power) such as a support or a crocodile, the frictional resistance is further increased, and the palm is rubbed against the material to correct the position. A considerable amount of force (grip strength) is required for the work, and as a result, the degree of fatigue of the worker is extremely large, and there is a problem in continuing the work for a long time.

Therefore, in order to solve the above-mentioned problems, the present invention partially improves each bite plate pair of the bite member so that the bite plate pair and the bite plate pair are attached thereto. The pantyhose material in which the frictional resistance with the material is made as small as possible so that the position correction work in the width direction of the material can be easily and quickly performed and the burden on the operator is significantly reduced. It is an object of the present invention to provide a mounting device for the.

[0024]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a rotation rotatably supported on the outer surface of each of a pair of left and right upper and lower bite plates which constitutes a bite member. The configuration is such that the members are arranged over substantially the entire length of the pair of bite plates in the length direction.

Further, the rotating member is arranged so as to be divided into at least two or more parts in the front and rear direction with respect to the lengthwise direction of the bite plate pair.

[0026]

The operator holds the open part of the waist band made of a pair of materials by hand, and attaches the part from the open part to the panty part to the respective predetermined positions of the upper and lower bite plate pairs. Next, the attached panty portion is moved in the width direction on the pair of biting plates in the upper and lower directions, and the boundary line or mark formed on the panty portion is arranged at the position on the center line of the pair of biting plates. Alternatively, the position is corrected so that the marks are vertically aligned.

This position correcting work facilitates the panty portion, which is attached to the biting plate pair in a tensioned state, in the width direction thereof by the rotating action of the rotating member provided on the outer surface of the biting plate pair. In addition, it can be moved quickly, and as a result, it is possible to reduce the work of mounting work accompanied by position correction and improve efficiency by shortening the time.

[0028]

Embodiments of the present invention will be described below with reference to the drawings. The basic structure of the bite member of the present invention is

1 to 3, the bite member 12 of the present invention comprises left and right arms 15 and 15 having a pair of left and right bite plate pairs 13, 13 and 14, 14 and a pair of left and right sides. The pair of bite plates is supported by the arms 15 and 15 so as to be reciprocally rotatable so as to expand from the state parallel to each other along the circumferential orbit line of the carrier 11 (see FIG. 4) of the crotch sewing machine. In addition, the pair of upper and lower bite plates are configured so as to be capable of press contact and separation.

Then, the above-mentioned pair of left and right upper and lower biting plates 1
Rotating members 50, 50 and 60, 60 having the same shape and structure are arranged on the outer side surface of each of 3, 13, 14 and 14 over substantially the entire length of the pair of bite plates.

As shown in FIGS. 2 and 3, the bite plate pair 1
A concave portion 51 is formed by cutting the outer side surface of each of the outer peripheral surfaces 3 and 13 except the front portion 13a and the rear portion 13b over the entire length in the remaining length direction in a semicircular shape in cross section. The hollow rotating member 50 is fitted in (state of FIG. 3).

The front part 13a and the rear part 13b of the pair of bite plates 13 and 13 are provided with through holes 52 and 53 such that the axes thereof coincide with the axis of the rotary member 50 fitted in the recess 51, Then, the hollow shaft 54 is inserted between the through holes 52 and 53 to fix both ends of the hollow shaft 54 in the through holes.

To insert the hollow shaft 54 into the through hole, the first through hole 53 is inserted first, and then the other through hole 52 is inserted through the hollow of the rotary member 50. The member 50 is rotatably supported by the hollow shaft 54 while being fitted in the concave portions 51 of the bite plate pairs 13, 13.

In the hollow of the hollow shaft 54, as shown in FIG.
Both ends of the flexible guide rod 55 are inserted as shown in FIG.

Although the above description has described the structure of the rotary member 50 arranged on the upper left and right bite plate pairs 13, 13, the rotary member arranged on the lower left and right bite plate pairs 14, 14 is described. The structure of 60 is exactly the same as that described above, and as shown in FIG. 3, the rotating member 60 is fitted in the recess 61 formed in the outer surface of the bite plate pair 14, 14 and the hollow shaft 64 It is pivotally supported.

The pantyhose material mounting apparatus of the present invention is constructed as described above, and the operator holds the bite member 1 at the first work station I (FIG. 4) of the crotch sewing machine.
It is located in front of 2, and of the pair of materials, one material is mounted between the upper left and right bite plate pairs 13 and 13 and the other material is mounted between the lower left and right bite plate pairs 14 and 14, respectively. . At the time of this mounting, the material is guided from the inside by the guide rod 55, so that the mounting work can be performed smoothly.

When the work of mounting the material between the pair of upper and lower bite plates is completed, the operator next checks whether or not the panty portion of the mounted material is placed at a predetermined position on the pair of bite plates. After confirming in step 1, if it is deviated from the predetermined position, position correction work will be performed.

This position correction work is carried out by moving the panty portion of the material mounted on the pair of bite plates in the width direction (circumferential direction).
Since 0 (60) is arranged, the operator only needs to rotate the rotating member while gently pressing it with the palm of the hand, and what is the movement of the panty portion in the width direction with respect to the bite plate pair? It is extremely easy to carry out without any resistance.

Then, the above-mentioned three-dimensional materials SC ₁ and S
If C _2, the boundary line 21 formed in the panty portion 2 as shown in FIG. 11, also bikini type of material SB _1,
If it is SB ₂ , as shown in FIG.
Is moved in the width direction so as to be arranged at the position on the center line between the pair of upper and lower right and left bite plates, and the position is corrected so that the boundary line 21 and the marks 31, 32 of each material match vertically. .

The total length of the panty portion of the material attached to the pair of bite plates is about 300 to 350 mm, which is a considerable length, and the panty portion is moved in the width direction at a time to perform position correction work. That is the front part (waistband side)
And the rear part (garter line side) may be difficult to match. This is especially difficult when the stitches of the material are twisted.

Therefore, in the present invention, the rotating member 50 (6
0) is divided into at least two or more parts (not shown) in the front-back direction with respect to the length direction, so that the position correction work in the width direction of the panty parts attached to the bite plate pair is performed as the front part. It can be carried out separately in the rear part, whereby the above-mentioned problems can be solved.

[0042]

As described above, according to the present invention, rotatable rotary members are arranged on the outer side surfaces of the pair of upper and lower biting members and the pair of left and right biting members of the biting member. By mounting the material to be mounted so as to cover this rotating member, the position correction work by moving the material mounted on the pair of bite plates in the width direction is extremely effective without any resistance due to the rotating operation of the rotating member. It can be carried out easily, and as a result, the work efficiency of the mounting work can be reduced by reducing the work time.

Further, even if the panty portion is a long material or a twisted material of stitches, the rotary member is divided into front and rear parts and the position correction work of the material is divided into the front part and the rear part. The position correction work can be performed easily and quickly.
