Abstract

PURPOSE:To improve the productivity by automatically performing a series of work in which left and right selvages of a raw fabric are cut off, measuring and cutting takes place after bottom stitching and chain stitching are carried out, an edge of the cut-out fabric is bottom stitched and the other edge is sewed together with a lining. CONSTITUTION:A raw fabric 1 wound in a roll-shape is held by a raw fabric holder 2 and led to selvage serging devices 5a and 5b via a raw fabric pool 4 and both selvages are cut and serged. Then, both selvages are processed by a selvage sewing machine where both selvages are folded double or triple and chain stitched. Then, the curtain fabric is pulled out onto a table 8 and its front edge is inserted into a lateral conveyer 10 and the curtain fabric is pulled out. At this time, the length of the fabric pulled out is measured by a measuring roller. The curtain fabric is pulled out by a specified length and cut by a cutting device. Then, its one edge bottom stitched by a bottom stitching machine 21 and the other edge is sewed together with a lining by a lining sewing machine 22.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the perspective view of FIG. 1, a curtain sewing machine according to the present invention includes a raw fabric holding portion 2 for holding a raw fabric 1 wound in a roll shape, and a raw fabric 1 for replenishing the raw fabric 1. The anti-splicing device 3 that splices the anti-spindle 1, the raw fabric pool 4 that pools a fixed amount of the original fabric 1 in a zigzag shape so that the stable supply can be performed even during the anti-splicing work, and the raw fabric. Binaural surging device that cuts the left and right ears of the ears, and then performs overedging in order to stop the unraveling of the warp threads and remove the slings.
It is equipped with a series of devices for processing ears, which are a and 5b and binaural sewing devices 6a and 6b for performing chain stitching by winding three ears or folding them in two.

A cloth pool 7 for stably supplying the raw material 1 having the ears processed to the next step, and a necessary amount of the raw material material is spread to visually check for scratches, misalignment, etc. Is a table 8 for obtaining the dimensions required for pattern matching, and the required length, repeat length, based on the data obtained on this table 8.
The measuring device 81 for inputting the required number of sheets, and this measuring device 81
It is provided with a series of devices including a cutting device 9 having a rotary blade that cuts each of the predetermined lengths (lengths) sent out based on the data input in.

There is provided a lateral conveying device 10 for laterally feeding the curtain material 1a thus cut to a predetermined length in a direction parallel to the cut surface.

As shown in the side view of FIG. 2, in the lateral transfer device 10 surrounded by the frame body 11, a measuring roller 82 for measuring the length of the cloth 1a and a measuring length for a predetermined length are measured. In addition to a cutting device 9 composed of a rotary blade for cutting the woven fabric 1a, the woven fabric 1a is installed in parallel in the frame body 11 at intervals, and the front and rear ends of the woven fabric 1a are grasped in the lateral direction (direction perpendicular to the paper surface). ), A pair of lateral feed conveyors 12a and 12b, a holding device 13 that holds the tip of the dough 1a and places it on one of the conveyors 12b, and a feed roller 14 that sends the dough 1a with the dough held therebetween. .

Material cut by the lateral conveying device 10
A hem sewing device 21 (Fig. 1) that double-stitches the hem by winding the hem three times while transferring 1a in the horizontal direction, and at the same time while transferring in the horizontal direction, fold the top and sew while sandwiching the core tape. And a centering and sewing device 22 (FIG. 1) for performing attachment.

Next, the operation of the thus constructed curtain sewing machine will be described.

As shown in the perspective view of FIG. 1, an original fabric 1 wound in a roll shape is held by an original fabric holding portion 2, and the original fabric 1 is passed through a raw fabric pool 4 to a binaural surging device 5a, 5b. Guide, cut the left and right ears of the material, at that time, stop the warp,
After performing overedging to remove the slings,
In the both-ear sewing devices 6a and 6b, both ears are wound three times or folded in two, and chain stitches are applied to process the ears.

The dough 1a whose ears have been treated in this way
Is pulled out onto the table 8 through the dough pool 7 and visually inspected for flaws in the dough, and the tip of the dough 1a is inserted into the lateral transfer device 10.

When the original 1 held in the original holding unit 2 is consumed and runs out, while the original stored in the original pool 4 exists, the next original is supplied and spun back. The devices 3 are spliced together and the supply of the original fabric is continued.

In the lateral conveying device 10, as shown in FIGS. 2 (a) to 2 (j), (a) the feed roller 14 is moved to the origin while being opened, and the holding device 13 is also used as a measuring roller.
(B) The material extruded by the measuring roller 82 and the driving roller 83 while being advanced to the exit of the 82 and the driving roller 83.
The tip of the lapping device 13 is clamped by the clamping device 13, and (c) the clamping device 13 is fed at a speed lower than the speed at which the dough 1a is extruded by the measuring roller 82 and the drive roller 83.
After retreating to the origin outside the b, the feed roller 14 is also retracted to the inside of the lateral feed conveyor 12a, (d) the feed roller 14 is closed to sandwich the material 1a, and (e) the feed roller 14 pushes it out. The dough 1a is pulled out, and the dough 1a is loosened between the lateral feed conveyors 12a and 12b.

(F) When the measuring roller 82 detects that the fabric 1a having a predetermined length has been fed, the feeding roller 14 is opened, (g) the feeding roller 14 is returned to the origin, and then the lateral feeding conveyors 12a, 12b. Down the pressing members 15a, 15b,
(H) The guide 91 is lowered and the cutting device 9 including a rotary blade
To cut the cloth 1a.

(I) Air is jetted from the nozzle 16 to give a cloth
Both ends of 1a are aligned with the horizontal feed conveyors 12a and 12b, and (j) the cloth 1a is provided between the horizontal feed conveyors 12a and 12b and the pressing members 15a and 15b.
The fabric 1a is conveyed in a direction perpendicular to the paper surface with the paper sandwiched therebetween.

As shown in FIG. 1, the material 1a, which is cut and fed laterally, is double-stitched by winding the hem three times by the hem sewing device 21 while being conveyed in the lateral direction. The sewn device 22 is used to sew while bending the top and sandwiching the core tape.

When a flaw is found in the cloth 1a on the table 8, after passing through the steps (a) to (e), the portion where the flaw exists is passed through the cutting device 9 and then cut. The device 9 is operated to cut the dough, and the holding device 13 and the feed roller 14 are opened to remove the dough.
