Description

[Detailed Description of the Invention] [Industrial field of application] In this invention, in a sewing machine for bead sewing, a bead cloth is set in a predetermined bending state on a body cloth placed on a sewing machine table. The present invention relates to a woven cloth setting device.

[Conventional technology]

Generally, a sewing machine for bead sewing has a cloth W on the body cloth W _1.
An automatic cloth setting device for setting ₂ in the state shown in FIG. 9 is provided.

FIG. 8 is a diagram showing an example of a conventional automatic edge setting device.

As shown, the body fabric W ₁ placed on the sewing machine table M is pressed by a pair of body clamp 1 which is arranged via a predetermined welting patch placed intervals. Further, the pad cloth W ₁ is sent out one by one to the pad cloth receiving plate 3 for each set operation by a pad cloth feeding device (not shown), and the cross section of the pad cloth W ₂ has a substantially inverted T shape at the center thereof. Lower the binder 4 of the bottom plate 4
Are bonded onto the bedding W ₁ . On the lower surface of the bottom plate portion 4a, a cloth holding needle (not shown) is provided so as to be retractable, and is held by this needle. After that, the binder 4 is moved forward (in the direction of arrow A) as shown in FIG. 8 and the held cloth is positioned above the pair of body clamps 1 and 2 described above. Descends vertically. As a result, the cloth cloth W ₂ held by the binder 4 descends between the body clamps 1 and 2, and thereafter, the body clamps 1 and 2 are clamped.
Provided retractably fabric folding plates 1a, 2a is towards the inwardly projecting, side portions W _{2 a} of the welting patch W ₂ which is held, W
_{2 b} is in the folded along the bottom plate portion 4a of the binder 4 ideally so that the set state as shown in FIG. 9 is obtained.

[Problems to be solved by the device]

However, in the above-mentioned conventional cloth setting device,
When the woven cloth W ₂ has a soft cloth quality, both sides W ₂ a and W ₂ b of the woven cloth W ₂ held by the binder hang down in a nearly vertical state, and thus when the binder 4 descends. As shown in FIG. 11, the both side portions W ₂ a and W ₂ b are crushed between the body material W ₁ and the binder bottom plate portion 4a,
There was the inconvenience that proper setting could not be performed.
As shown in FIG. 10, a rod 5 protruding forward is provided on the lower surface of the pad cloth receiving plate 3, and the left side portion W ₂ a of the held pad cloth W ₁ is held.
It is also proposed that the left side portion W ₂ a is prevented from hanging down by hooking. However, in this device, although the setting failure of the left side portion W ₂ a of the pad cloth can be prevented to some extent, the setting failure similar to that of FIG. 11 occurs in the right side portion W ₂ b. Therefore,
In the welting patch set device including a rod 5 as described above, targeted set of only the left portion W _{2 a} ball cloth W _2, is effective for the so-called strip Welt, It cannot be applied to the beading W ₂ for both bead edges as described above. Also, regarding the left side portion W ₂ a of the pad cloth W ₂ , when the width is narrow or the cloth quality is low, the left side portion W ₂ a slips down before the binder 4 descends to some extent, There is a risk that the product may hang down and a set defect may occur, so a sufficient set defect prevention effect could not be expected.

This invention was made in view of the problems of the above-mentioned conventional device, and a bedding set device capable of properly and reliably setting a bead on the body cloth in forming both bead and one bead. For the purpose of providing.

[Means for Solving the Problems]

In this invention, a pad cloth gripping member having a substantially inverted T-shaped cross section which can be gripped so as to be freely released is moved laterally and downward from a pad cloth receiving plate to press the cloth cloth gripping member against the body cloth. In this automatic cloth setting device, the pad cloth gripping member is lowered between the first body clamp that presses the body cloth and the second body clamp that is juxtaposed with the first body clamp. On the lower surface of the pad cloth receiving plate, a pad cloth drip prevention plate projecting from one side of the receiving plate is provided, and at least the first pad cloth receiving plate of the body clamp is collapsed with a predetermined height from the upper surface thereof. A preventive plate is provided, and air injection means is provided for injecting air obliquely upward from the first body clamp to the second body clamp side between the first body clamp and the bedding fall prevention plate provided above the first body clamp. is there.

[Action]

In the present invention, the lining cloth on the lining cloth receiving plate is gripped by the lining cloth gripping member, and then moves laterally and downward together with the lining cloth gripping member, so that the first garment body clamp and the second garment body clamp are connected. Descend in between. At this time, when the grasped woven fabric is a woven fabric for both edges, one end portion of the woven fabric is lowered together with the woven fabric holding plate, and the woven fabric dripping prevention plates provided in the upper and lower two stages. The one side portion of the pad cloth does not hang downward from the bottom plate portion of the pad cloth holding plate during the setting operation, and is properly bent by the cloth folding plate after descending to the body cloth. Further, the other side portion of the cloth may hang downward from the cloth holding member at the beginning of the descent, but when it descends to some extent, it is jetted upward by the air jetted obliquely upward from the air jetting means.

Therefore, the proper set state can be obtained also on the other side portion.
