Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fabric setting device for a sewing machine that sews together cylindrical fabrics of a skirt outer material and a lining book.

[Prior art] For example, in order to sew a zipper to a sewn product such as a skirt,
It is customary to sew the lining, to which the zipper has already been sewn, to the outer material.

In this step, the operator first inserts the cylindrical lining into the fabric placing table as shown in FIG.
1 to position and fix it, and then place the cylindrical outer material on the cloth mounting table T. ! Cover the wl, outer material w2
After positioning the fastener attachment part and the lining wl, a cloth setting operation is performed in which both the cloths are held between the cloth holding plates P.

After setting the cloth, the clamping plate is pulled out from the cloth table T, the cloth is placed and fixed together with the clamping plate P on the sewing machine, and the fastener attachment part is sewn in a U-shape to complete the sewing work.

[Problems to be solved by the invention] By the way, 1. With a normal cloth at table T, a worker or a worker stands in front of the table and places his or her hand comfortably near the seam of the set cloth. The length is set so that it can be held in place, and the width is set so that the fabric can be easily inserted through it.

Therefore, in the case of a fabric with a certain length and diameter, such as a skirt, the part of the fabric supported on the table T is only a small part around the seam, and the other part is at the rear end of the table T. It will hang downward from the front and side edges. Therefore, when covering the outer material W2 over the lining material Wl set on the Iat table T, the operator must tuck the drooping part W l a of the lining material into the opening of the outer material W2 while covering it with the outer material W2. However, since this work is troublesome, work efficiency is significantly reduced and production costs are increased. On the other hand, the weight of the tucked lining Wl is added to the outer material W2, and the presser member P etc. ! ! When fixing W2, attach the outer material W
The positioning work in step 2 became difficult to perform, which adversely affected setting performance.

This invention was made by focusing on the above-mentioned problem, and
To provide a fabric setting device for a sewing machine for sewing cylindrical fabrics, which can smoothly and easily cover a lining fabric with an outer fabric on a mounting table T.

[Means for Solving the Problems] The present invention is provided with a moving means for vertically moving a predetermined holding member below the cloth mounting table.

[Function] In this invention, after the lining is set, if the holding member is raised by the moving means, the hanging portion of the lining is lifted upward by the holding member and is supported near the bottom surface of the fabric placement table. Therefore, the outer material can be easily applied! ! It can be placed over the lining on the stand, and when the outer material is fixed, the weight of the drooping part of the lining is not applied to the outer material, and the outer material does not shift.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to FIGS. 1 to 3.

In the figure, l is one cloth aW supported by a support column 2 on the floor F, and a fastener locking pin IC is attached to the front upper surface of the cloth aW.
Inverted U-shaped members 1a and 1b are fixed to the lower surface as protrusions projecting downward. Reference numeral 3 denotes a cloth holding plate provided on the upper surface of the front part of the cloth holding table l so as to be openable and closable, and 4 denotes a mounting base, which is located in front of the support column 2. 5 is a four-bar link mechanism rotatably connected to the mounting base 4. This four-bar link mechanism 5 has one end attached to the mounting base 4 with a shaft 5a,
Two long first and second links 51 pivoted at 5b
．． 52, and a dogleg-shaped third link 53 which is pivotally attached to the other ends of both links 51 and 52 by shafts 5c and 5d. 6a
, 6b are two wooden rods serving as supporting members, one end of which is fixed to one end of a rotating member 7, and the central portion of this rotating member 7 is rotatably connected to a shaft 5d. Reference numeral 8 denotes a cylinder whose one end is rotatably connected to the end of the third link 53 and the other end to the end of the rotating member 7 by shafts 8a and 8b, and is expanded and contracted by a drive device (not shown). . 9 has one end attached to the support stand 10 and the other end attached to the first link 51, respectively, with shafts 9a and 9.
The cylinders are rotatably connected at b, and, like the cylinder 8, are expanded and contracted by an external drive device.

Based on the above configuration, the operation will be explained next.

As in the conventional case, the outer material W2 of the skirt is inserted through the cloth mounting table l, and fixed by engaging the locking pin 1c with the hole of the slider f1 of the fastener f. After this, when the worker operates a pedal outside the section, the cylinder 9 extends from the state shown in FIG. 1 and pushes the first link 51 backward, moving the entire four-bar link 5 from the position shown in FIG. Move it to the position shown in Figure 2. As a result, the rods 6a and 6b move below the inverted U-shaped members la and lb, respectively (see FIG. 2(b)), and come into contact with the hanging portion W1a of the lining Wl. At this point, the cylinder 8 is in an extended state similar to the initial state shown in FIG. 1, and the rods 6a and 6b are tilted downward with respect to the cloth placing table l.

Next, when the operator depresses the pedal again, the cylinder 8, which had been in an extended state, contracts and rotates the rotating member 7 and the rods 6a, 6b in the direction of arrow B about the shaft 5d. As a result, the hanging portion W 1 a of the lining Wl is lifted by the rods 6a, 6b, and finally each rod 6a
, 6b are inserted into the inverted U-shaped members 1a, lb, thereby being folded into an E-shape as shown in FIGS. 3(a) and 3(b).

After that, one worker opens the opening of the outer material W2 and covers the lining material W1, but at this time, the drooping portion W of the lining material Wl is
Since 1a is folded into the inverted U-shaped members 1a and 1b, it can be easily placed over the lining Wl without any modification. Moreover, when the outer material W2 is fixed by the presser member 3, the weight of the drooping portion of the lining material wl is not applied to the outer material W2, so there is no problem of the outer material being displaced after being positioned.

After firmly fixing the outer material W2 with the presser member 3, when the pedal is depressed, the cylinder 9 first contracts and moves the four-bar linkage mechanism 5 in the direction of arrow C, leaving the rods 6a and 6b in a horizontal state. It is pulled out from the lining Wl. Then, the cylinder 8 is extended and the rotating member 53 is rotated in the direction of the arrow.
The rods 6a and 6b are rotated in the same direction to return to the initial state. However, in the above embodiment, the two rods 6
a and 6b, and by inserting these into the inverted U-shaped members la and lb, the outer material Wl can be folded into an E-shape, or depending on the size of the fabric, the rods and the inverted U-shaped members can be folded. Two or more may be provided, or the lining storage effect may be slightly inferior compared to the above embodiment, or the supporting member may be simply a plate-like member instead of a rod. It is possible to achieve the initial objective of the present invention without forming a protrusion on the lower surface, and the present invention is not particularly limited to the above embodiment.

In addition, in the above embodiment, a four-bar link mechanism is used as a moving means, and the presser member (rods 6a, 6b) is operated to be pulled out from the lining Wl after fixing the fabric. It is also possible to apply other means of transportation.

[Effects of the Invention] As explained above, 39, according to the present invention, when setting the lining and the outer fabric on the cloth mounting table, the outer fabric can be smoothly and easily covered with the set lining,
While the work efficiency is significantly improved, when fixing the outer material, the weight of the 1A drooping part is not added to the outer material, and it can be set accurately at RT, resulting in low-priced and high-quality sewn products. You can get it.
