The injection pipe is provided with a required number of injection holes for compressed air formed so as to face the knitting yarn running surface and the yarn guide of the knitting yarn supply device.

In the knitting machine, compressed air required for knitting in its function is introduced. Therefore, by connecting a part of the compressed air introduced into the knitting machine to one end of the injection pipe via a branch hose or a valve, the fly waste removing device of the present invention does not require a large-scale auxiliary device. , Can be configured as an extremely inexpensive device.

The injection of compressed air from the injection hole is performed by controlling the opening and closing of the valve.
In this case, it is possible to control by setting a time limit by a timer or to control based on an electric command from the knitting machine. However, in order to reduce costs, in the present invention, a timer or the like is not newly used. The valve is controlled to open and close based on an electric command from the knitting machine.

Although the numerical value is not particularly limited, as a result of repeated experiments by the present inventor using the fly waste removing apparatus of the present invention, the time interval for opening the valve and injecting compressed air from the injection hole ( Cycle time) is about 1 to 3 minutes, the injection time is 2 to 5 seconds, and the injection pressure is 0.8 to 2.0 kg / c.
The result shows that it is preferable to set m.

That is, during the operation of the knitting machine, the knitting yarn supply is controlled by controlling the compressed air of 0.8 to 2.0 kg / cm to be injected from the injection holes at intervals of about 1 to 3 minutes for 2 to 5 seconds. The amount of fly waste accumulated in the device is extremely small, it can be blown off easily and instantly without sticking, the consumption of compressed air is small, and there is no adverse effect on the running knitting yarn or knitting machine side. In addition, the fluff and the like that are blown off are also scattered outside the machine.

Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show various knitting yarn supply devices.
A tension control device for a knitting yarn is illustrated, and an embodiment in which the fly waste removing device of the present invention is attached to the tension control device will be described below.

In FIGS. 1 and 2, a tension control device 10 for a knitting yarn Y includes a yarn guide
3 and a fixing plate 14 and a pressing plate 15 which are disposed between the yarn guides 12 and 13 and face each other on both sides connecting the center lines (travel paths of the knitting yarn Y) of the yarn guides 12 and 13. I have.

As shown in FIG. 1, the pressing plate 15 is mounted on a rotating member 16 formed in a C-shape so as to come into contact with the fixed plate 14 via a spring 17 so that the pressing plate 15 is attached. By adjusting the force with the nut 18, the contact pressure of the pressing plate 15 with respect to the fixed plate 14 (tension application to the knitting yarn Y) can be arbitrarily set.

The tension control device 10 constructed as described above
Then, the knitting yarn Y fed out from the bobbin is supplied from the top to the bottom in the drawing, that is, first passes through the yarn guide 12, then passes through the space between the fixed plate 14 and the pressing plate 15, reaches the yarn guide 13, and is supplied to the knitting machine side. Will be done.

As a result, a predetermined tension is applied to the knitting yarn Y supplied to the knitting machine by the surface pressure action of the fixed plate 14 and the pressing plate 15 which come into contact with each other by the urging force of the spring 17. .

On one side of the base 11 of the tension control device 10, an injection pipe 21 composed of a single hollow pipe is attached at a position very close to the running path of the knitting yarn Y.

As shown in FIG. 2, a plurality of (three in this embodiment) injection holes 22 are formed in the injection pipe 21.
These injection holes 22 are arranged so as to be directed toward the upper ends of the yarn guides 12 and 13 of the tension controller 10 and the fixed plate 14 and the pressing plate 15 (in the direction of the arrow in FIG. 2).

That is, in the tension control device of this embodiment, the knitting yarn Y travels from the top to the bottom in the drawing, and this travel causes the yarn guides 12 and 13 and the respective portions between the fixing plate 14 and the pressing plate 15 to move. The fly is most likely to collect at the upper end. Therefore, the injection holes 22 are arranged so as to be directed to a portion where the fly waste is most likely to accumulate.

The injection pipe 21 has one end closed and the other end connected to a compressed air introduction pipe (not shown) supplied to the knitting machine via a hose 23 via a branch pipe or the like. The hose 23 is provided with a valve 24 at an appropriate position.

The valve 24 is controlled to open and close based on an electric command from the knitting machine. When the valve 24 is opened, compressed air is blown out from the injection hole 22.

The fly waste removing apparatus of the present invention has the above-described configuration. To remove fly waste and the like adhering to each part of the tension control device 10, first, the valve 24 is opened and the waste cotton is introduced into the knitting machine. The compressed air that has flowed into the injection pipe 21 through the hose 23 and then the compressed air is injected from the injection holes 22 formed in the injection pipe 21, so that the wind accumulated in each part of the tension control device 10 is controlled. Cotton and the like are instantly blown off and are scattered outside the knitting machine.

The opening and closing of the valve 24 is controlled by transmitting an electric command from the knitting machine, for example, every time the knitting operation of one pair of socks is completed, to open the valve 24 and to close the valve 2 to 5 seconds after the opening. What is necessary is just to control.

[0027]
