Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a stride sewing stacker for automatically and continuously folding and hanging trouser fabrics after the stride sewing.

<Conventional technology and its problems> Conventionally, when sewing trousers with long legs, the fabric is sewn with a large stitch using a sewing machine, and the sewing thread is not cut but is placed in a continuous state on the sewing machine table. 1. The sewing worker and another worker picked it up, cut the seam thread, separated the adjacent pieces of trouser fabric, and folded and collected them all. , which are usually piled up at appropriate locations, making the work extremely complicated, resulting in poor work efficiency and requiring a lot of manpower, which is a bottleneck in converting this type of sewing process into an automated line.

Means for Solving the Problems> The present invention is intended to solve these problems, and is intended to be used as a stacker for long stitches that automatically removes the stitches from the sewing machine table after the automatic sewing machine finishes sewing long strides. A first phototube is supported to face the drooping position of the trousers fabric that is fed out forward so as to hang down, and detect the position of the advancing front end of the fabric; a second photocell for detecting the position of the advancing rear end; and a second phototube that is erected in advance in a backward tilted state from the stacker installation base on the work floor so that it can automatically receive the position near the front end of the dough hanging from the table. , and a fabric transfer arm that is operated so as to be tilted forward about an assembly pivot at its lower end with respect to the installation base; additionally pivoted at a mid-height position of the transfer arm; and based on the position detection of the advancing front end by the first phototube, the cloth is tilted backward in order to press and clamp the hanging cloth at a position near the front end between it and the transfer arm. The first dough holding arm is also attached to the transfer arm at a mid-height position, and based on the position detection of the advancing rear end by the second phototube, the position near the rear end of the hanging dough is detected. , a second fabric presser arm which is also operated in a rearward tilted state to hold and clamp the fabric between the first fabric presser arm; The dough hanging stand facing from the rear at approximately the mid-height position of the dough is suspended from the installation base at a position forward of the receiving stand, and the dough is clamped by the second dough holding arm. After that, in order to clamp and fix the fabric at approximately the middle position between it and the receiving stand, the lower end of the fabric is assembled to the installation base. The hanging table, together with the receiving table, clamps and fixes the fabric at approximately the middle position, and then the fabric transfer arm intersects with the hanging table in an X-shape when viewed from the side. In order to operate the fabric in a reverse tilted state and to release the clamped state of the fabric at the position near the front end and the position near the rear 51, both fabric presser arms are moved relative to the transfer arm. The first feature is that the fabric is transferred from the transfer arm to the hanging table in a hanging half-folded state by operating the sewing machine in the forward tilting and unfolding state. Using an automatic sewing machine, the trouser fabric is sewn in a wide-legged state with the entire leg open, with the hem on one leg serving as the leading edge, and the remaining hem on the other leg being used as the trailing edge. In order to feed the dough forward so that it hangs down from the front end of the table, there is a dough feed roller installed on the table so as to be able to rise and fall freely, and a dough feed roller that is supported at the hanging position of the dough and feeds the dough forward so as to hang down from the front end of the table.

Action> To explain in detail the present invention configured as described above, the trouser fabric (M) that has been subjected to the stitching action of the sewing machine (11) on the table (10) has the hem portion of one leg The front end (a) is the hem of one leg, and the hem of the remaining leg is the rear end (a).
As shown in b), the fabric is fed forward in the direction of the arrow (P) by the fabric feeding roller (14) and automatically hangs down from the front end of the tee pull (10). The stacker, which receives the hanging fabric (M) from below, is initially waiting in the posture shown in Figure 1.2.5.

Therefore, the position of the pre-advancing part (a) of the drooping fabric (M) is first detected by the first phototube (24), and based on the detection action, the first fabric first pile presser arm (42) is activated. , tilted backward by the air cylinder (45) so as to come into contact with the land transfer 7-m (37)! S Nikosaku UJ
Then, as shown in Figure 6, both arms (37) (42
), press and clamp the fabric (M) near the front end. At that time, the fabric (M) was still sewn by the sewing machine (1
1), and is still being advanced forward by the feed roller (14), so the front end of the clamped material is suspended from a part of the horizontal bar of the first material presser arm (42). At the bottom, the fabric (M>) gradually hangs down from its waist (e) as shown in Figure 7.8.

Eventually, when the long stride sewing of the fabric (M) is completed, the sewing thread (12) is automatically cut by the thread cutting knife (13) of the sewing machine (11), and the trailing edge (b) of the fabric (M) is cut automatically. The position is detected by the second phototube (25). Then, based on the detection action, the rotation of the feed roller (14) is stopped, and the second fabric presser arm (43) is moved backward so as to come into contact with the first fabric presser arm (42), as shown in FIG. The air cylinder (46) is operated to clamp the fabric (M) at a position near the 1&end between the front and rear of the presser arms (42) and (43) so that the presser arm (42) is in a tilted state. On the other hand, at the same time as this action or immediately after, the fabric feed roller (14) is moved 19 away from the sewing machine table (10) to free the fabric (M) from sagging on the trailing edge side, and to The fabric (M) is maintained so that it can be inserted into the roller (14) or sewing machine (11).

Next, the fabric hanging table (28) is operated by its air cylinder (33) to change its posture to a rearward tilted state where it comes into contact with the receiving table (27) as shown in FIG.
Therefore, the drooping fabric (M) is clamped and fixed at approximately the middle position between the front and rear of the lilies (27) and (28). At that time, the fabric pinching arm (30) attached to the hanging stand (28) is
1), it is activated in advance to the opposite forward tilting state as shown in FIG.

Then, while the fabric (M) is held and fixed at approximately the middle position, the fabric transfer arm (37) is then moved to the hanging table (28) using the air cylinder (39) as shown in Fig. 11. The transfer arm (37) is operated to tilt forward so as to intersect in an X-shape when viewed from the side, and as soon as the transfer arm (37) is (43), as shown in Fig. 12, as if expanding the
Release the clamp state near the front end T and the position near the back end of the fabric (M) above, and hang the fabric (M) on the hanging table (
28) in an almost perfectly half-folded shape.

In that case, after releasing the clamped state by both presser arms (42) and (43), the fabric clamping arm (30) attached to this is brought into contact with the fabric hanging stand (28).
As shown in FIG. 13, the cloth (M) is made to tilt backward by an air cylinder (31), and the hanging cloth (M) is stably clamped and fixed.

Finally, by operating the air cylinder (33), the hanging table (23) on which the fabric (M) is hung is lifted from the receiving table (27) as shown in Fig. 14. By returning to the front and keeping it in its original upright position, by repeating this I-cycle operation, the trouser material (M) that has been sewn over the stride is successively
The fabric can be hung and stacked on the fabric hanging stand (28).

When the hanging trigram is completed on the hanging stand (28), as suggested from Figures 2 and 14,
Both hem portions (Ll) (b) and waist portion (C) of the pants fabric (M) overlap correctly, and are folded in half into a +51 vertical U-shape from approximately the midpoint of the overall length. . Incidentally, the time required for the 1'' cycle is about 18 to 22 seconds, and about 25 pairs of pants (12 oz denim) can be hung and stacked on the fabric hanging stand (28). It goes without saying that the above one cycle operation is automatically controlled by a sequence circuit including switches and a timer.
