Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting yarn supply device, and more particularly, a knitting machine in which knitting yarns wound on a large number of bobbins mounted on a creel stand are individually passed through a tube by a jetting force of compressed air. The present invention relates to a knitting yarn supply device adapted to be fed to the side.

[0002]

2. Description of the Related Art When a knitting yarn is fed to a knitting machine, particularly a circular knitting machine, a creel stand (hereinafter referred to as "creel") is generally installed adjacent to the knitting machine, and a bobbin is attached to the creel. A large number of knitting yarns are mounted, and the knitting yarns wound on these bobbins are individually supplied to the knitting machine side via a yarn guide and a tension control device.

By the way, in the knitting yarn supplied from the creel to the knitting machine side, the fly yarn generated during the traveling of the knitting yarn is scattered to deteriorate the working environment in the factory, or the scattered fly yarn. In addition to the dust and the like in the factory, this adheres to the running knitting yarn, which causes a knitting failure in the knitting machine.

Therefore, conventionally, in order to prevent the fly cotton from scattering due to the running of the knitting yarn, a tube (hollow thin tube) for individually feeding the knitting yarn between the creel and the knitting machine is used. The knitting yarn is passed through the tube and supplied from the creel to the knitting machine side.

As described above, in order to provide the knitting yarn between the creel and the knitting machine and to feed the knitting yarn through the tube to the knitting machine side, the knitting yarn is first passed through the tube as the first preparation work for knitting Is required.

For this reason, conventionally, a special air gun or the like having a groove for guiding the knitting yarn at the tip thereof is used, and the operator himself presses this air gun against one end of the tube to inject compressed air from the air gun. The knitting yarn is passed through the tube.

[0007]

However, the diameter (caliber) of the tube is only a few millimeters, while the length is several to several tens of meters and the tube is bent, so that the end of the tube is bent. Compressed air does not flow accurately in the tube due to the deviation of the pressing angle of the air gun to be pressed or a slight gap is created, and as a result, the work requires a considerable amount of time and a skilled worker. There was a problem that I could not do it otherwise.

Moreover, the work of passing the knitting yarn through the tube is one
In the first preparatory work, not in a book or two, it is necessary to pass several tens of knitting yarns through the tube for one knitting machine, and when a yarn breakage occurs during knitting, each time It is necessary to perform the threading operation quickly, and therefore, it is the current situation that the operator strongly desires the appearance of a device that can easily thread the thread.

The present invention has been made in view of the above problems of the prior art. An operator sets a knitting yarn on the supply device by attaching the knitting yarn supply device of the present invention to the tube end located on the creel side. It is an object of the present invention to provide a knitting yarn supply device that can reliably and quickly supply a knitting yarn through the tube to the knitting machine side simply by performing a simple and simple operation of pressing a switch.

[0010]

In order to achieve the above object, the present invention comprises a single housing having a compressed air supply part and a compressed air discharge part, in which a compressed air introduction chamber is provided. And a lead-out chamber are provided, and a switch is provided between the lead-in chamber and the lead-out chamber to manually switch both chambers from the closed state to the open state, and the lead-out chamber is supported on its lower surface side by an elastic material, An injection nozzle is provided so that the upper surface side is in close contact with a thread guide having a knitting thread insertion groove, and when the knitting thread is set in the insertion groove of the thread guide, the injection nozzle interposes an elastic material. It adopts a structure that sinks into the lead-out room.

As shown in FIG. 2, the knitting yarn Y is set by the operator holding the yarn ends A and B with both hands and pushing in the direction of the arrow through the gap between the jet nozzle 23 and the yarn guide 26. Is sunk downward through the elastic material 25, and as a result, the knitting yarn Y can be set in the insertion groove 28 of the yarn guide 26 quickly and easily.

As described above, the knitting yarn Y is set in the insertion groove 28 of the yarn guide 26 even if the upper surface of the jet nozzle 23 and the lower surface of the yarn guide 26 are in close contact with each other. The injection nozzle 23 should be sunk into the outlet chamber 16 by the thickness (thread diameter) of the knitting yarn through the elastic material 25 simply by pushing inward through the gap formed in the outer peripheral portion of both. When the knitting yarn Y is set in the insertion groove 28, the elastic material 25 restores the jet nozzle 23 and the yarn guide 2.
6 will be returned to the close contact state again.

As described above, when the knitting yarn Y is set in the insertion groove 28 of the yarn guide 26 on the upper surface of the jet nozzle 23,
Next, the operator pushes the head portion 20a of the switch 20 protruding outside the housing 11 to eject the compressed air from the jet nozzle 24, and the jet air feeds the knitting yarn Y to the knitting machine 31 side through the tube 33. I will send it.

That is, the pushing operation of the switch 20 by the operator causes the introduction chamber 15 and the discharge chamber 1 which have been in the closed state until then.
6 is opened and compressed air is allowed to flow out to the outlet chamber 16 side. The compressed air that has flowed out into the outlet chamber 16 is then ejected from the ejection hole 24 of the ejection nozzle 23 through the hollow hole of the elastic material 25, and further from the hole 27 of the yarn guide 26 through the tube 33. By flowing in the machine 31 direction, the knitting yarn Y set in the insertion groove 28 of the yarn guide 26 is fed to the knitting machine 31 side through the tube 33 along the flow of the compressed air. .

The feeding operation of the knitting yarn Y in the tube by the compressed air is continued while the operator is pressing the switch 20, and the knitting yarn Y is fed to the end of the tube 33 located on the knitting machine 31 side. The work is completed by stopping the pushing operation of the switch 20 at the time of sending.

When the pushing operation of the switch 20 is stopped, the partition plate 21 of the switch 20 is returned to the original position by the force of the coil spring 22, and the introduction chamber 15 and the discharge chamber 16 are returned.
And are returned to the closed state.

In this way, when one knitting yarn Y has been supplied to the knitting machine 31 side through the tube 33, the operator pays out the knitting yarn Y from the next bobbin, and repeats the above operation. The knitting yarns Y are sequentially supplied to the knitting machine 31 side through the tube 33.

[0031]

As described above, according to the present invention, the operator unwinds the knitting yarn from the bobbin by an appropriate amount, sets the yarn end in the insertion groove of the yarn guide, and then pushes the switch. Only by this, the knitting yarn is fed in the tube by the flow of the compressed air jetted from the jet nozzle, and is instantly fed to the knitting machine side. As a result, the work of supplying the knitting yarn through the tube can be significantly speeded up and simplified as compared with the conventional one, and the efficiency therefor and the burden on the worker engaged in the work can be significantly reduced. .

When the compressed air is jetted from the jet nozzle, the jet nozzle and the yarn guide are in close contact with each other,
As a result, the compressed air that is ejected does not leak to the outside,
It accurately flows in the tube and reliably feeds the knitting yarn along the tube to the knitting machine side.
