Description

[Detailed explanation of the invention] [Industrial field of application] This invention sets an upper frame and a lower frame that sandwich the sock and the embroidery paper piece when performing one-point embroidery on the side of the leg of a sock using an embroidery sewing machine. This invention relates to an automatic sheet 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. To load socks into the embroidery sewing machine, as shown in Fig. 6, use a piece of paper P and an oval upper frame The surface is kept under tension. The paper piece P is a firm core-like material for beautifully applying embroidery to a stretchable knitted fabric. In this way, the pieces of paper and the frame are set by an autosetter.

As shown in FIG. 7, in this conventional autosetter, six radial arms 42 are fixed to a rotating shaft 41, and the whole unit rotates intermittently (see the direction of the arrow in FIG. 5). A rectangular piece of paper P is supplied to the tip, a lower frame Y is stacked on top of the paper piece at position B, a sock S is inserted through the opening at position C, and an upper frame X is supplied at position D. Then, the socks and pieces of paper are sandwiched between the lower frame Y, and at position E, the part of the socks outside the frame is pushed into the brim of both frames by an automatic device, and moved onto the conveyor 44 by the swinging arm 43, and automatically placed in the receiving box. 45 is being discharged repeatedly.

[Problem that the invention attempts to solve]

However, in this automatic sock embroidery setter, feeding the paper strips P at position A is done manually by the operator, and there has been a demand for an automatic paper strip feeding device that mechanizes this process to save labor.

[Means for solving problems]

This idea was developed to solve the above-mentioned problems, and includes a pair of rollers that intermittently feed paper tape from a paper roll, a paper cutter installed close to this pair of rollers, and a It consists of a feeder that supports cut pieces of paper and supplies the pieces of paper to a predetermined location on the arm of the autosetter. It consists of a suction cup that is detachably supported and supplies it to the autosetter.

[Effect]

According to this invention, a paper tape is fed out from a paper roll by a pair of intermittently rotating rollers, and is cut in a timely manner by a paper cutter into pieces of paper of the required size, which are sucked and supported by a suction cup connected to a vacuum pipe. It is automatically supplied sequentially to a predetermined position on the arm of the autosetter via a rail.

〔Example〕

1 to 5 show examples of this invention. The automatic paper strip feeding device of this sock embroidery autosetter is installed at position A of the autosetter as shown in FIGS. A pair of rubber rollers 2 to be fed out, a scissor-shaped automatic paper cutter 3 installed close to the pair of rubber rollers 2 in the exit direction, and an end portion of an arm 42 of the autosetter that supports a piece of paper P cut to a required size. A feeder 5 that supplies paper pieces P to the oblong recess 4 of
The feeder 5 consists of a rail 6 that extends between the paper cutter and the arm 42 of the autosetter, and a suction cup 7 that reciprocates along this rail 6 and supports the paper piece P in a detachable manner. It's summery.

The paper tape 1 fed out from the paper roll is held between a pair of rubber rollers 2 via a guide roller 8.
It is fed out to a required length, for example, 120 mm, stops, and is automatically cut with a paper cutter 3 at a good timing to become a piece of paper P and left on the table 9. This piece of paper P is
A suction pipe 10 is connected to the suction cup 7, which moves up and down by an air cylinder, and is sucked and supported on the lower surface of a suction cup 7 which moves reciprocally along the rail 6 by an air cylinder, and is left after being supplied to the recess 4 of the arm 42. and,
It comes to be attracted to a small hole 11 connected to a hollow pipe installed in the recess 4.

As shown in FIGS. 3 to 5, the arm 42 of the auto setter has a hollow pipe 12 connected to the small hole 11 for adsorbing paper pieces attached to the center thereof, and this hollow pipe 12 is bent on the lower surface of the rotating shaft 41. It's open. Furthermore, a vacuum joint member 13 (see details in FIGS. 4 and 5) is fixed to the top surface of the base 46 and is in surface contact with the bottom surface of the rotating shaft 41, so that a vacuum joint member 13 (see details in FIGS. 4 and 5) is fixed only between positions A and B. Manku pipe 1 with arm 42 on the pump
2 are arranged in a row.

The true joint member 13 has an arcuate groove 14 concentric with the rotating shaft 41 in its upper half, and a groove 14 in the center of its lower half.
4 is buried therein, and an oval rubber packing ring 16 is fixed to the periphery of the groove 14 on the top surface, so that airtightness is maintained even when the rotary shaft 41 slides into surface contact with the lower surface of the rotating shaft 41. .

Note that since the piece of paper P is pressed by the supplied lower frame Y at the position B, there is no need to vacuum-adsorb it through the small hole 11 from the position C onwards.

When using the automatic paper strip feeding device of the automatic sock embroidery setter of this invention, a paper roll wrapped with a long paper tape is loaded onto the spindle, and the tip of the drawn paper tape is caught between the pair of rubber rollers 2. ,
By simply pressing the ON button of the auto setter's drive switch, the paper pieces P can be automatically fed one by one into the recess 4 of the arm 42 that rotates intermittently.

〔effect〕

As described above, according to the automatic paper strip feeding device for the autosetter for sock embroidery according to this invention, the paper strips that serve as a core for beautifully embroidering the stretchable sock knitted fabric are automatically fed to the arm of the autosetter. A of the conventional auto setter
This has the effect of being able to omit the need for a worker in this position, greatly contributing to labor savings.
