Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock inverting device for inverting a tubular sock cloth.

[0002]

2. Description of the Related Art Generally, a tubular sock cloth knitted in a sock factory by a circular sock knitting machine in a face-up state is generally sewn with an overedging machine at the leading edge of the sock cloth in the next step. Therefore, it is necessary to turn it over. If this inside-out process is carried out manually, the sock fabric is easily damaged and the work efficiency is poor. Therefore, a socks-up device equipped with a plurality of sock-reversing cylinders on the turntable (actual fair 2-26).
No. 957) or the like was used, socks were inserted into the cylinder, and the socks were turned over.

[0003] In such a sock-reversing device, by simply inserting a cylindrical sock into a sock reversing cylinder, the cloth can be automatically returned to either the front or back surface without damaging the cloth. Although the efficiency is increased as compared with the case where the sock is returned, the insertion of the tubular sock into the cylinder is done by hand, and the workability thereof has been demanded to be improved. In addition, the inventor of the present application is the Japanese Patent Application No. 3-108.
In No. 42, we proposed a sock insider-out device that can improve the above-mentioned work, but since the number of parts is large and the operation is complicated,
The improvement was demanded.

[0004]

SUMMARY OF THE INVENTION As described above, according to the present invention, the step of manually inserting the sock cloth after knitting by the circular sock knitting machine into the sock inverting cylinder is an obstacle to improving the work efficiency. Solve the problem of becoming
An object of the present invention is to directly knit a knitted tubular sock cloth directly and continuously without manual work, and to do this by a device having a relatively simple structure.

[0005]

In order to solve the above-mentioned problems, according to the present invention, a cloth sock knitting machine of a circular type sock knitting machine is equipped with an upper end opening having an intake hole in a peripheral wall midway in the axial direction. A cylinder is arranged. This inner cylinder is rotatable about its axis and can be moved up and down in the axial direction. An intake pipe is connected to the lower end of the cylinder. The upper opening of the inner cylinder is closed and rotated at the upper position of the inner cylinder. A rotating shaft with a plug for transmitting power is arranged, an outer cylinder is attached to the outside of the inner cylinder, and a support ring for supporting the lower end of the cloth is fixedly provided in the middle of the outer cylinder. A structure in which a cylindrical airtight chamber that airtightly covers the outer peripheral wall of the inner cylinder is formed inside the lower outer cylinder is adopted.

[0006]

In the sock inverting device according to the present invention, the tubular sock material knitted by the circular sock knitting machine with the inner cylinder being raised is placed between the outer peripheral surface of the inner cylinder and the inner peripheral surface of the outer cylinder. Since it is pulled downward by the flowing intake air, sock fabric is inserted into the inner cylinder at the same time as knitting. At this time, the tubular sock fabric is rotated by the knitting operation of the circular sock knitting machine, but the inner cylinder rotates in the same direction in conjunction with the stopper-equipped rotating shaft at the raised position, so that it is entangled with it. It doesn't. After knitting, when the sock fabric is separated from the knitting machine and the inner cylinder is lowered, the rotation of the inner cylinder stopped from the rotation axis stops, and the intake holes on its peripheral wall are located in the cylindrical airtight chamber inside the outer cylinder. Since it is closed in, the intake air is taken from the upper end opening of the inner cylinder. At this time, the sock cloth is supported at its lower end by the support ring and is prevented from moving downward,
As the inner cylinder descends, the inner cylinder is drawn into the upper end opening from its upper part, turned inside out, and transferred in the suction pipe.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, in the embodiment, an inner cylinder 3 having a long hole-shaped intake hole 2 in a peripheral wall midway in the axial direction is rotated around an axis in a shuttle 1 of a circular sock knitting machine. A rotary shaft with a plug, which is provided so as to be freely movable up and down in the axial direction, connects an intake pipe 4 to a lower end of the inner cylinder 3, and seals an upper end opening 3a at a rising position of the inner cylinder 3 and transmits rotational power above the shuttle 1. 5 are arranged.
An outer cylinder 6 is attached to the outer side of the inner cylinder 3, a support ring 7 supporting a tubular sock cloth A is fixed in the middle of the outer cylinder 6, and the inner side of the outer cylinder 6 below the support ring 7 is fixed. A cylindrical airtight chamber 8 that hermetically covers the outer peripheral wall of the inner cylinder 3 is formed therein.

The inner cylinder 3 has a length of the required sock material A of about 2
It is formed with a double length, and a plurality of intake holes 2 are arranged at equal intervals in the circumferential direction so as to penetrate the peripheral wall in the middle thereof. As shown in FIGS. 1 and 2, the lower end of the inner cylinder 3 has a connecting ring 9
Further, the thrust bearing 10 and the hose joint 11 are connected in this order to the intake pipe 4 to enable intake in a rotatable state around the axis. The intake pipe 4 is made of a flexible synthetic resin or a pipe 4a having a bellows structure, and can follow up and down movements of the inner cylinder 3. The end of such an intake pipe 4 is connected to a vacuum pump 14, a sock discharge box 15 is installed in the middle of the pipe, and a sock cloth A is taken out by appropriately opening a bottom plate 15a thereof. .

As shown in FIG. 3, a crown-shaped projection 12 is formed on the upper end opening 3a of the inner cylinder 3 which is moved up and down, and at its raised position, a disc 5a having a multi-row key groove 13 on the boss portion. The rotary shaft 5 with a stopper is engaged in an airtight state. Such a rotary shaft 5 with a plug is fixed to a housing (not shown) or the like, and rotational power corresponding to a rotational speed suitable for knitting the sock fabric A is input only to the inner cylinder 3 in the raised position. .

Further, as shown in FIG. 1, the outer cylinder 6 is the inner cylinder 3
And the upper half is made to have a small diameter upper part 6a to approach the outer peripheral surface of the inner cylinder 3 to improve the efficiency of sucking the sock cloth A. In the lower half thereof, as a large-diameter lower portion 6b, a lid 16, a support ring 7 and a seal ring 17 are attached to the inner upper portion, and a guide tube 18 also serving as a seal is attached to the inner lower portion to form a tubular airtight chamber 8. A large number of small holes 7a are formed on the bottom surface of the support ring 7 so that the lower end of the sock cloth A to be sucked can be received when the intake hole 2 of the inner cylinder 3 is positioned below. The inside of the upper end edge of the guide tube 18 is in airtight sliding contact with the inner tube 3 via a radial bearing 19 that rotatably guides, and the lower end edge is in airtight contact with the inner tube 3 via a connecting ring 9. Further, a flange 22 for attaching the base end of the rodless cylinder 21 is formed on the outer side of the guide cylinder 18.

The rodless cylinder 21 is driven by an actuator (not shown), and a slide ring 23 that moves up and down is connected to the lower end of the inner cylinder 3 via a hose joint 11.

The operation of the above embodiment will be described with reference to FIGS.

First, as shown in FIG. 1, a tubular sock fabric A knitted inside a shuttle 1 of a circular sock knitting machine has a support ring 7 and an air intake hole 2 from between an inner cylinder 3 and an outer cylinder 6. It is pulled downward by the descending airflow flowing into the intake pipe 4 through and is inserted into the rotating inner cylinder 3 without being entangled.

Next, as shown in FIG. 4, after the knitting, the separated sock material A is lowered onto the support ring 7. At this time, when the inner cylinder 3 is lowered by the rodless cylinder 21, the intake hole 2 passes through the seal ring 17 and enters the cylindrical airtight chamber 8 inside the outer cylinder 6, so that the intake air from the intake hole 2 is cut off. Instead, intake is performed from the upper end opening 3a released from the rotary shaft 5 with a plug. In this way, the sock cloth A is drawn into the upper end opening 3a in order from the upper part to the lower part, and is turned inside out.

The rodless cylinder 2 of the above embodiment
The base end of No. 1 and the guide tube 18 may be attached to a base (not shown) fixed separately, and the type of fluid cylinder can be selected and used without limitation. Further, the outer cylinder 6 may be appropriately changed in upper and lower diameters, and the volume of the cylindrical airtight chamber 8 is formed as small as possible so that the large diameter lower portion 6b and the required portion of the inner cylinder 3 are slidably contacted with each other. Of course it's good.

[0017]

As described above, the sock inverting device of the present invention does not require the knitted tubular sock cloth to be manually inserted into the reversing cylinder (inner cylinder), and the inner cylinder can be knitted at the same time as knitting. The dough can be transferred to the next step in a state of being smoothly turned inside out by pulling the dough into the inner cylinder from the upper part only by the operation of inserting and lowering the inner cylinder. Therefore, the device having a small number of parts and a relatively simple structure can dramatically improve the efficiency of the manufacturing work of the tubular sock cloth, and can be said to be highly useful in industry.
