Description

[Detailed description of the invention] The present invention relates to a super ring spinning machine.

In other words, the present invention relates to a ring spinning machine characterized by extremely high performance.

As is well known, a conventional ring spinning machine surrounds the outer periphery of a bobbin 2 supported on a spindle 1 shown in FIG.
a ring 6 and a try 2 supported on the ring
4 exists.

Therefore, when installing the well-known "suction twisted pipe S including air vortex generating means" according to the inventor's previous invention to this ring spinning machine, first, There is the trouble of having to insert the spun yarn Y into the trapella,
Furthermore, it dawned on me that there was a difficult problem in having to wind the end of the inserted spun yarn Y onto the bobbin 2 on the spindle.

In other words, as a result of the existence of this troublesome and difficult problem becoming clear to the mind, the problem of installing the above-mentioned suctioned twisted pipe S into a ring spinning machine has continued to be solved by the inventor of the present application. There was no one to consider.

However, recently, the inventor of the present application once again became interested in the above-mentioned problem, and as a result of conducting a detailed study on the advantages and disadvantages of putting this problem into practice, he I am now able to confirm that most of the labor and challenges are nothing more than frustration.

To further explain the reason in detail with reference to embodiments shown in the accompanying drawings, a front roller button 11 of a well-known ring spinning machine and
Between the extension center line ＼X2 above the spindle, there is a suction twisted tube S (i.e., a funnel-shaped inner tube a at the head) including a means for generating an air vortex according to the previous invention of the present inventor. A combination of an outer pipe surrounding the outer circumference with a required gap of c%H is provided, and compressed air is fed from an air inlet 11.d that communicates with the gap C from a tangential direction. By,
The front roller 1 is attached thereto by providing an air vortex generating means (including means for generating an air vortex to swirl around the gap and to pass through the narrowed end of the funnel-shaped inner tube a while being narrowed).
It was found that the drafted slipper F to be delivered from 0.11 contains a white spinning principle in the air vortex of the suction twisted tube.

In other words, this spinning machine sucks the drafted slipper F sent out from the front roller button 11 of the drafting device into the suction twisted pipe S that includes means for generating an air vortex. As a result, if fibers tend to adhere to the outer surface of the front roller 10.11 and tend to get wound up in the tray.

It was also found that the fibers were immediately automatically sucked into the air vortex in the sucking and twisting tube, and were narrowly bundled together with the group of fibrils of the sliver F to form a thread.

In other words, if there is a tendency for the fibers to become entangled, which would cause yarn breakage, to occur, the suction force of the air vortex of the suction twisted tube is used to immediately prevent the entanglement. It has been found that there are significant effects that can be achieved.

The fact that the occurrence of yarn breakage during spinning can be prevented beforehand, rather than being a simple trick, also means that the troubles and difficulties that the inventor of the present application feared at the beginning did not exist at all. Therefore, it can be said that in addition to incorporating the spinning principle of high-quality spinning, a super ring spinning machine with revolutionary superior performance has been constructed, with no fear of yarn breakage during spinning. .

-Ro- Furthermore, compared to the well-known ring spinning machine that is commonly used both domestically and internationally, this super ring spinning machine has a relatively simple mechanism and its manufacturing cost is low. It is sufficient to attach the suction control pipe S, and it has the feature that it can produce the remarkable effects as described above.

Therefore, the normal rotational speed of the spindle will be reduced by at least 30% in the future.
It is believed that the above-mentioned increase in performance, combined with the above-mentioned increase in performance, will result in significant labor savings.

In other words, the present invention relates to a ring spinning machine characterized by extremely high performance. As shown in the accompanying drawings, a conventional ring spinning machine has a ring 3 surrounding the outer periphery of a bobbin 2 supported on a spindle 1, and a traveler 4 supported on the ring.
exists. Therefore, for this ring spinning machine, the present inventor's previous invention "suction twisted pipe S including an air vortex generating means" was applied.
'', there is the difficult problem of having to wind the end of the thread Y onto the bobbin 2 on the spindle. In other words, as a result of the existence of this troublesome and difficult problem becoming clear to the mind, the inventor of the present application, of course, was unable to solve the problem of installing the above-mentioned suctioned twisted pipe S in a ring spinning machine. There was no one to consider. However, recently, the inventor of the present application regained a new interest in the above-mentioned problem when he had a chance to lose his job, and after doing a detailed study on the advantages and disadvantages of putting this problem into practice, he found that We have come to the conclusion that most of the difficult problems are nothing more than a bummer. To further explain the reason in detail with reference to an embodiment shown in the accompanying drawings, there is a structure between the front roller 10.11 of the known ring spinning machine and the extended center lines X, A suction twisted tube S (i.e., a combination of a funnel-shaped inner tube a at the head and an outer tube surrounding the outer periphery with a gap C of a required degree), which includes the air vortex generating means according to the invention
In addition, an air inlet pipe d is provided which communicates with the gap C from a tangential direction, and the gap is rotated and narrowed by the action of the compressed air to be injected from the air inlet pipe. The drafted slipper F to be sent out from the front roller 10.11 is attached thereto (including means for generating an air vortex to be spirally flowed by scooping the narrowed end of the funnel-shaped inner tube a). Spinning principle of high-quality spun yarn (see Patent No. 940517), which automatically sucks into the air vortex of the suction twisted tube, narrowly focuses it, and turns it into a yarn form. It was found to contain. In other words, in this spinning machine, the drafted slipper F sent out from the front roller button 11 of the tensioning device is sucked into the suction twisted pipe S containing the air vortex generating means. As a front roller 10.
When fibers are tightly attached to the outer surface of the sliver 11 and try to be wound into the fibers, the fibers are immediately sucked by the air vortex in the suction twisted tube S and return to the fibril flow of the sliver F. +! Together, they narrowly converge and form a thread. That is, when a phenomenon occurs in which the fibers that are wound up and become the cause of yarn breakage occur, the fibers are immediately corrected in their posture by the suction force of the air vortex of the suction twisted tube, and It has now been found that this method has a remarkable effect in preventing winding curls. Needless to say, the ability to prevent yarn breakage during spinning also means that the troubles and difficulties that the inventor of the present application feared at the beginning did not exist at all. Coupled with the above-mentioned features including the spinning principle of high-quality spun yarn, it can be said that we have been able to provide a super ring spinning machine with groundbreakingly excellent performance. In contrast to the well-known ring spinning machine, which is commonly used in non-rotating machines at home and abroad, we have developed a suction twisted tube S, which has a relatively simple mechanism and low manufacturing cost. It is sufficient to attach it, but it has the feature that it can produce the remarkable effects as mentioned above. Therefore, the normal rotational speed of the spindle will be reduced by at least 30% in the future.
In addition to being able to increase the efficiency by about 50%, in conjunction with the above-mentioned increase in performance, it is thought that a significant increase in efficiency should be realized. 4.
