This invention relates to an automatic frame feeding device for an autosetter.

[Conventional technology]

Conventionally, one-point embroidery on the side of the leg of socks has been performed with high efficiency using a multi-head embroidery machine. In order to load socks into the embroidery machine, as shown in Fig. 10, a piece of paper P, an oblong upper frame X and a lower frame Y are required.
The sides of the legs of the sock S are held between the legs and the fabric surface on which the embroidery is to be applied is held under tension. The paper piece P is a core-like piece for beautifully applying embroidery to a stretchable knitted fabric. Such sheet and frame setting is performed by an autosetter.

As shown in FIG. 11, this conventional autosetter has six radial arms 42 fixed to a rotating shaft 41 and rotates intermittently as a whole (see the direction of the arrow in FIG. 11). There is a piece of paper P on the tip of
At position B, feed the bottom frame Y overlapping the pieces of paper, at position C, insert the sock S through the opening, and at position D, supply the upper frame X and combine it with the bottom frame Y. The sock and piece of paper are held between each other, and at position E, the part of the sock outside the frame is pushed in by an automatic device inside the flanges of both frames, and the sock is moved onto the conveyor 44 by the swinging arm 43 and automatically discharged into the receiving box 45. Such work is repeated.

[Problem that the invention attempts to solve]

However, in this automatic sock embroidery setter, the worker who supplies the piece of paper P at the position A, and the worker who supplies the piece of paper P at the position A,
A large number of workers are required, including a worker who supplies the lower frame Y at position C, a worker who sets socks at position C, and a worker who supplies the upper frame X at position D, resulting in high labor costs. There was a request for an automatic feeding device for our lower and upper frames.

[Means for solving problems]

This invention was developed to solve the above-mentioned problems, and includes a frame storage cylinder that rotates at an angle of inclination, a conveyor that loads the frames sent out from the cylinder into a sock embroidery autosetter, and a feeder, the cylindrical body is provided with a spiral plate on the inner circumferential surface in order to move the frame upward in a line;
The width of this spiral plate is gradually narrowed as it goes upwards.One frame can be placed at the end, and the upper end of the spiral plate serves as a frame delivery port, and the conveyor is equipped with a pair of guide rollers. A frame changing device and a frame sensing operation switch are provided, and the feeder attracts and moves the frames on the conveyor and automatically loads them into the sock embroidery autosetter in sequence.

[Effect]

According to this invention, a large number of frames placed in an inclined cylinder are agitated as the cylinder rotates, slide on a spiral plate, and gradually move upward (see Figure 6). Since the width of the spiral plate becomes narrower as it goes upward, excess frames are shaken off, and finally they are lined up in a row and sent out one by one from the upper end frame delivery port to the conveyor. On the conveyor, the frames are aligned in the same direction by the frame changing device (see Figure 7), are lifted by the suction cup of the reciprocating feeder, and are automatically fed to predetermined positions of the intermittently rotating arm of the sock embroidery autosetter. .
