[0005]

In order to solve the above-mentioned problems, according to the present invention, an inner cylinder for cloth insertion for upper end opening having an intake hole in a lower peripheral wall is arranged inside a shuttle of a circular sock knitting machine. Then, a suction pipe is connected to the lower end of this inner cylinder, and the inner cylinder is attached to the base so as to be rotatable around the axis and movable up and down in the axial direction, and the upper end opening is sealed above the inner cylinder above the shuttle. And a rotary shaft with a plug that transmits rotary power is placed,
An outer cylinder is attached to the outer circumference of the inner cylinder via a vertically movable support cylinder, and a support ring for supporting the lower end of the cloth is provided on the support cylinder.
In addition, a structure is adopted in which a ventilation path is provided that connects the intake hole and the upper part of the support cylinder when the air cylinder descends.

[0006]

In the sock inverting device according to the present invention, the sock fabric knitted by the circular sock knitting machine is pulled downward by the intake air flow flowing into the ventilation passage between the outer peripheral surface of the inner cylinder and the inner peripheral surface of the outer cylinder. , Insert the sock cloth at the same time as knitting along the outer circumference of the inner cylinder. At this time, the inner cylinder is interlocked with the rotating shaft with the stopper in the raised position,
Since the fabric rotates with the fabric, the fabric is not entangled with the fabric and does not hinder the knitting. After knitting, the sock cloth is separated from the knitting machine, the inner cylinder is lowered, and the support cylinder is further raised.When the rotation power from the rotary shaft is cut off, the rotation of the inner cylinder is stopped and the intake air from the ventilation passage is removed. After stopping, air is taken in from the upper end opening of the inner cylinder. At this time, since the lower end portion of the sock cloth is lifted by the support cylinder along the inner cylinder, the sock cloth is smoothly drawn into the inner cylinder from the upper side and turned inside out, and is 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 an elongated hole-like intake hole 2 in a lower peripheral wall is arranged inside a shuttle 1 of a circular sock knitting machine, and a suction is made at a lower end of the inner cylinder 3. In addition to connecting the pipe 4, the inner cylinder 3 is attached to the base 5 via the radial bearing 6 so as to be rotatable and movable up and down by the fluid cylinder 7, and the rotary shaft 8 with a plug is arranged above the shuttle 1. On the outer periphery, an outer cylinder 11 is externally mounted via a support cylinder 10 supported by a magnetic body 9 so as to be able to move up and down.

As shown in FIG. 2, the inner cylinder 3 is in airtight sliding contact with a mounting hole 12 penetrating the base 5 via an O-ring 13 and is rotatable about its axis via radial bearings 6 and 14. Yes, it can be moved up and down by the fluid cylinder 7 connected to the radial bearing 14. The lower end of the inner cylinder 3 is attached to the suction pipe 4 via the bellows 15 so as to be able to move up and down. However, the suction pipe 4 as a whole has flexibility, or a well-known slidable structure is used together or the bellows 15 is provided. Instead of this, it may be lifted and lowered. As shown in FIG. 1, the end of the suction pipe 4 is connected to a vacuum pump 16, a sock discharge box 17 is installed in the middle of the pipe, and a bottom plate 17a thereof is installed.

8, a small diameter portion 20 having a peripheral wall formed with a communication hole 19 communicating with the intake hole 2 of the inner cylinder 3, and a support ring 21 having a circular groove-shaped notch 21a at the peripheral edge. If the above-mentioned communication hole 19 is formed to have a large area that is at least twice as large as the opening area of the intake hole 2, both holes can be surely matched. Also,
The lower ring 18 is provided with a diameter that allows the outer peripheral surface of the inner cylinder 3 and the inner peripheral surface of the outer cylinder 11 to be in sliding contact with each other in an airtight manner. The support cylinder 10 is
When it is mounted between the inner cylinder 3 and the outer cylinder 11, it is slidable and can be raised and lowered, and the air passage that passes through the communication hole 19 and the upper part of the support cylinder 10 by the clearance due to the diameter difference between the small diameter portion 20 and the outer cylinder 11. 10a (see FIG. 2) is formed.

It is preferable that the outer cylinder 11 is made of a non-magnetic material such as stainless steel or a synthetic resin material so that the lower ring 18 can be smoothly moved up and down, and an elevating ring 22 having a plurality of magnetic bodies 9 attached to its outer circumference. Exterior. Such an elevating ring 22 is connected to a fluid cylinder 23 fixed to the base 5 via an arm 24, and holds the supporting cylinder 10 by magnetic force to elevate it appropriately (see FIG. 1 or FIG. 2).

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

First, as shown in FIG. 4 (a), the tubular sock fabric A hanging inside the shuttle 1 of the circular sock knitting machine has a ventilation passage 10a and an intake air from between the inner cylinder 3 and the outer cylinder 11. It is knitted while being pulled downward by the descending airflow flowing into the suction pipe 4 through the hole 2 and rotating together with the inner cylinder 3.

Next, as shown in FIG. 4 (b), after knitting,
The separated sock material A descends on the support cylinder 10.
At this time, when the inner cylinder 3 is lowered by the fluid cylinder 7, the intake hole 2 and the communication hole 19 are separated from each other, and the ventilation passage 10a is cut off by coming into contact with the inner peripheral surface of the mounting hole 12 or the outer peripheral surface of the inner cylinder 3, respectively. Instead of this, intake is performed from the upper end opening 3a released from the rotary shaft 8 with a plug.

Then, as shown in FIG. 4 (c), when the fluid cylinder 23 is driven to raise the support cylinder 10 by magnetic force, the sock cloth A is smoothly drawn into the inner cylinder 3 through the upper end opening 3a. It will be turned over.

In the above embodiment, the support cylinder 10 is moved up and down from the outside of the outer cylinder 11 by the magnetic force of the permanent magnet, but it is needless to say that an electromagnet may be used.
Known lifting means such as pulling 0 with a linear member may be adopted.
