BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock turning device for turning over cylindrical sock fabric.

0002

[Prior art and its problems] Generally, cylindrical sock fabric is knitted face up by a circular sock knitting machine in a sock factory, and in the next process, the opening edge of the sock fabric is sewn with an overcut sewing machine. Therefore, it is necessary to turn it over. If this turning process is carried out manually, the sock material will be easily damaged and the work efficiency will be poor.
No. 957), etc., by inserting a sock into the cylinder and turning it inside out.

[0003] Such a shoe turning device can automatically turn a cylindrical sock to either the front or back side without damaging the fabric by simply inserting the cylindrical sock into the sock turning cylinder. Although this method improves efficiency compared to the case where the cylinder is turned by hand, inserting the cylindrical sock into the cylinder is done by hand, and there has been a need to improve the workability. In addition, the inventor of this application is
In No. 2, a sock turning device was proposed that could improve the above-mentioned work, but since the number of parts was large and the operation was complicated, improvements were needed.

0004

[Problems to be Solved by the Invention] As described above, the present invention solves the problem that the process of manually inserting the sock fabric after knitting with the circular sock knitting machine into the sock reversing cylinder is an obstacle to improving work efficiency. We have solved the problem of
The object of the present invention is to directly and continuously turn knitted cylindrical sock fabric without manual labor, and to do this using a device with a relatively simple structure.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a fabric inserting device with an upper end opening having an air intake hole in the circumferential wall in the middle in the axial direction, inside the pot of a circular sock knitting machine. A cylinder is arranged, and this inner cylinder is rotatable around the axis and can be raised and lowered in the axial direction, and an intake pipe is connected to the lower end of the inner cylinder. A rotating shaft with a stopper that transmits power is arranged, an outer cylinder is attached to the outside of the inner cylinder, and a support ring is fixedly provided in the middle of the inside of the outer cylinder to support the lower end of the fabric. A configuration is adopted in which a cylindrical airtight chamber is formed inside the lower outer cylinder to airtightly cover the outer circumferential wall of the inner cylinder.

[0006]

[Operation] The sock turning device according to the present invention turns the cylindrical sock fabric knitted by the circular sock knitting machine between the outer circumferential surface of the inner tube and the inner circumferential surface of the outer tube with the inner tube raised. Since it is pulled downward by the flowing intake air, the sock fabric can be knitted and inserted into the inner tube at the same time. At this time, the cylindrical sock fabric is being rotated by the knitting operation of the circular sock knitting machine, but since the inner tube rotates in the same direction in conjunction with the rotating shaft with a stopper in the raised position, it becomes entangled with this. It's fleeting. After knitting, when the sock fabric is separated from the knitting machine and the inner cylinder is lowered, the rotation of the inner cylinder away from the rotation axis stops, and the air intake hole on its peripheral wall is located inside the cylindrical airtight chamber inside the outer cylinder, making it airtight. Since the inner cylinder is closed, air is taken in from the upper end opening of the inner cylinder. At this time, the lower end of the sock fabric is supported by the support ring and is prevented from moving downward, so as the inner tube descends, it is pulled from the upper part into the upper opening and turned inside out, causing suction. transported inside the pipe.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples 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 an elongated intake hole 2 in the circumferential wall in the middle in the axial direction is installed inside a pot 1 of a circular sock knitting machine and rotates around an axis. An intake pipe 4 is connected to the lower end of the inner cylinder 3, and a rotating shaft with a plug is provided above the pot 1 to seal the upper end opening 3a in the raised position of the inner cylinder 3 and transmit rotational power. 5 is placed. An outer cylinder 6 is attached to the outside of the inner cylinder 3, and a support ring 7 for supporting the cylindrical sock fabric A is fixed to the middle of the inside of the outer cylinder 6. A cylindrical airtight chamber 8 is formed which airtightly covers the outer peripheral wall of the inner cylinder 3.

[0009] The inner cylinder 3 has a length of about 2 times the length of the required sock fabric A.
It is formed to have double the length, and a plurality of intake holes 2 are arranged at equal intervals in the circumferential direction by penetrating 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
It is connected to the intake pipe 4 via a thrust bearing 10 and a hose joint 11 in this order, so that air can be taken in while being rotatable around an axis. The intake pipe 4 is made of flexible synthetic resin or a pipe 4a having a bellows structure, and is capable of following the rise and fall of the inner cylinder 3. The end of the suction pipe 4 is connected to a vacuum pump 14, and a sock discharge box 15 is installed in the middle of the pipe, and the sock fabric A is taken out by opening the bottom plate 15a as appropriate. .

As shown in FIG. 3, a crown-shaped protrusion 12 is formed at the upper end opening 3a of the inner cylinder 3 that moves up and down, and at the raised position, a disk 5a having multiple rows of key grooves 13 is formed in the boss part. The rotating shaft 5 with a stopper is engaged with the rotary shaft 5 in an airtight manner. Such a rotary shaft 5 with a plug is fixed to a housing (not shown), etc., and inputs rotational power corresponding to a rotational speed suitable for knitting the sock fabric A only to the inner cylinder 3 in the raised position. .

Further, as shown in FIG. 1, the outer cylinder 6 is connected to the inner cylinder 3.
The upper half is made to have a small diameter upper part 6a and is brought close to the outer peripheral surface of the inner cylinder 3 to improve the efficiency of sucking the sock fabric A. Further, the lower half forms a cylindrical airtight chamber 8, with a lid 16, a support ring 7, and a seal ring 17 attached to the inner upper part, and a guide cylinder 18 which also serves as a seal, as a large-diameter lower part 6b. A large number of small holes 7a are formed in the bottom of the support ring 7 so as to receive the lower end of the sock fabric A that is sucked when the air intake hole 2 of the inner tube 3 is positioned downward. The inside of the upper end edge of the guide cylinder 18 is in airtight sliding contact with the inner cylinder 3 via a radial bearing 19 that guides the guide cylinder 18 so as to be rotatable, and the lower end edge is in airtight sliding contact with the inner cylinder 3 through a connecting ring 9. Further, a flange 22 is formed on the outside of the guide tube 18 to which the base end of the rodless cylinder 21 is attached.

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 explained based on FIGS. 1 and 4.

First, as shown in FIG. 1, a cylindrical sock fabric A is knitted inside a pot 1 of a circular sock knitting machine, and a support ring 7 and an air intake hole 2 are inserted between an inner tube 3 and an outer tube 6. It is pulled downward by the descending airflow that flows into the intake pipe 4 through the inner cylinder 3, and is inserted into the rotating inner cylinder 3 without getting entangled with it.

Next, as shown in FIG. 4, the cut-off sock fabric A is lowered onto the support ring 7 after knitting. 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 the intake air from the intake hole 2 is cut off. Instead, air is taken in from the upper end opening 3a released from the rotary shaft 5 with a stopper. In this way, the sock fabric A is sequentially drawn into the upper end opening 3a from the upper part to the lower part, and is turned inside out.

Note that the rodless cylinder 2 of the above embodiment
1 and the guide tube 18 may be attached to a separately fixed base (not shown), and the type of fluid cylinder can be selected and used without limitation. Further, the diameter of the upper and lower portions of the outer cylinder 6 may be changed appropriately, and the volume of the cylindrical airtight chamber 8 may be formed as small as possible, and the large diameter lower part 6b and the required portion of the inner cylinder 3 may be slidably contacted. Of course it's good.

[0017]

[Effect] As explained above, the sock turning device of the present invention eliminates the need to manually insert the knitted cylindrical sock fabric into the reversing cylinder (inner cylinder), By simply inserting the fabric into the inner cylinder and lowering the inner cylinder, the fabric can be drawn into the inner cylinder from the upper part, turned over smoothly, and transferred to the next process. Therefore, a device with a small number of parts and a relatively simple structure can dramatically improve the efficiency of manufacturing cylindrical sock fabric, and can be said to be of high industrial value.
