The present invention relates to a cloth delivery auxiliary guide device for a sewing machine, which is provided on a sewing machine main body to guide the forced delivery of the cloth. The sewing machine main body is provided with a cloth delivery device that folds, for example, a cloth cut into an unfolded shape of a sleeve portion of underwear. , Forcing the double-folded fabric to be forcedly distributed in the predetermined sewing direction along the length direction of the linear end edge portion of the upper and lower cloth portions overlapping each other; and the sewing section forcibly being distributed in the predetermined sewing direction by the fabric distribution device The thread-shaped sewing end edge portion of the cloth is cut (cut into pieces) such that the thread-shaped sewing end edge portion has a predetermined shape, and the thread-shaped sewing end edge portion after the cutting is sewn.

FIG. 10 shows, for example, a cloth W cut into the expanded shape of the sleeve in order to form a sleeve. When the sleeve is actually formed using the cloth W, the cut cloth W is folded in half along the line shown by the dotted line in FIG. 10. When the half-folded cloth W is set on the cloth plate of the main body of the sewing machine and forcedly delivered in a predetermined sewing direction by a cloth distributing device, the upper and lower cloth portions W1 and W2 respectively overlap the linear end edges W1e, W2e guides compulsory delivery by sequentially moving in the direction of the predetermined sewing progress direction, thereby cutting the extra protrusions of the linear end portions W1e, W2e, etc. with a cutter, and using the sewing section on the main body side of the sewing machine to cut After cutting, the linear end edges W1e and W2e of the upper and lower cloth portions W1 and W2 are sewn. Thereby, a sleeve portion having a predetermined shape is formed.

When the sleeve is formed, when only the cut fabric W is folded in half, and the sewing operator directly holds the folded fabric W with his hand to guide the forced delivery, not only the sewing operator is required to have a high degree of proficiency, but also Even if it is a highly skilled sewing operator, it is difficult to stably maintain the delivery positions of the linear end edges W1e and W2e due to the effects of hand vibration or mechanical vibration. Therefore, the cutting position of the cutter is deviated or meandered, and a cutting fabric of a predetermined shape cannot be obtained. In addition, the sewing position is also unstable during sewing after cutting. Therefore, the sewing products such as the sleeves are easily shaped. Indecent and poorly processed defective products.

As a means of suppressing the occurrence of this defective product, conventionally, as shown in Figs. 11A and 11B, a compulsory delivery of the cloth is guided by a jig called a guide plate. The guide plate T is configured to switch a pair of upper and lower plastic mold plates T1 and T2 having a shape similar to the upper and lower cloth portions W1 and W2 of the folded cloth W to the following two states: One end portion in the width direction serves as a bending fulcrum and is expanded into a flat state as shown in FIG. 11A; and a state where it is folded into two pieces as shown in FIG. 11B. In addition, a cloth edge positioning plate P is installed on the lower surface of the lower template T2 so that the position can be changed to two positions in the width direction by swinging the lower template T2. The two positions are: the cloth edge A position where the end edge Pe of the positioning plate P protrudes more outwardly than the end edge T2e of the lower profile plate T2; and a position retracted more inward than the end edge T2e of the lower profile plate T2.

Then, as shown in FIG. 11A, in a state where the above-mentioned pair of upper and lower profiles T1 and T2 are unfolded into a flat shape, the cloth W cut into the expanded shape of the sleeve is placed on the pair of profiles T1 and T2. On the unfolded plane. At this time, the cloth edge positioning plate P is changed to a position protruding more outward than the edge T2e of the lower profile T2, so that the position of the edge W2e of the cloth W and the edge T2e of the lower profile T2 are aligned. .

In this state, by folding the pair of profile plates T1 and T2 above and below the guide plate T as shown in FIG. 11B, the above-mentioned cloth W is folded in half, so that the upper and lower cloth portions W1 and W2 are overlapped and held. Between the upper and lower pair of profiles T1 and T2. The linear edge portions W1e and W2e of the upper and lower cloth portions W1 and W2 of the half-folded cloth W held and held are slightly exposed to the outside compared to the edge T1e of the upper profile T1 and the edge T2e of the lower profile T2. Of the state.

As described above, when the cloth W that is folded in half is clamped and held by the guide plate T between the pair of upper and lower profiles T1 and T2 to guide the forced delivery of the cloth W, the sewing cloth is directly held by the sewing operator with the hand Compared with the case of W, it is easier to handle, and it can stably guide the delivery position of the linear end edge of the cloth to prevent deviation or meandering of the cutting position. On the other hand, it is necessary to keep the guide firmly by hand. As for the plate T, it is still unavoidable that the cutting position and the sewing position are deviated or meandered due to the influence of hand vibration or mechanical vibration. As a result, there is a problem that a properly shaped and well-processed sewing product cannot be obtained.
