Abstract

PURPOSE:To eliminate the necessity of a running body such as a tape or belt, by engaging a rotor with a hollow support shaft supported between two pais of stepped pulleys, providing a stator for rotating the rotor in a specific state, and passing a high-frequency current through the stator. CONSTITUTION:The base part of a hollow support shaft and a protruding support shaft 2' passing protrusively through the hollow support shaft are supported between mutually adjacent left and right stepped pulleys 8, 8, 9 and 9, thereon. A rotor (R) is engaged with the hollow shaft, and a stator (S) is provided to rest at a position eccentric to the rotor (R). A high-frequency current is passed through the stator (S).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for increasing the speed of an open-end spinning frame, etc. In recent years, the well-known order has been asked.

However, this rotating means is not necessarily easy from a technical standpoint. In particular, regarding the developments of the present inventor in recent years,
When rotating the spindle of a draftable open-end spinning frame that includes inner and outer rotors, the diameter of the hollow spindle of the outer rotor of the spinning unit will inevitably increase slightly. It seems difficult to apply it immediately.

The purpose of the present invention is not only to increase the speed of the well-known open-end spinning frame described above, but also to easily apply it to the speed-up of such a new open-end spinning frame.
Furthermore, the present invention aims to dramatically improve the functionality of open-end spinning machines and the like by providing a method that makes it possible to rotate at ultra-high speeds exceeding 10,000 revolutions per minute.

The present invention will be explained below with reference to embodiments shown in the accompanying drawings, but the means for rotating the spindle of the rotor in the above-mentioned well-known open-end spinning machine are based on the present invention. It is possible to explain the new open-end spinning machine, which requires a special type of spinning machine, i.e., one that requires dual inner and outer rotors, as it becomes clear on its own. The explanation will be omitted and will mainly focus on this new open-end spinning frame.

In FIG. 1, reference numeral 1 indicates a rotor in a well-known open-end spinning frame, 2 indicates a spindle thereof, and R indicates a rotor to be fitted onto the spindle. In FIG. 2, 5 is the outer rotor, 4 is its hollow support shaft, 5 is the inner rotor, 6 is the inner wall surface of the outer rotor, and S is the opened fiber to be received on the inner wall surface. Fiber, S! indicates a sliver to be formed at the maximum diameter portion of the inner wall surface.

To explain this FIG. 2 in more detail, the base 4' of the hollow support shaft 4 and the protruding support shaft 2' that can protrude through it are placed between the adjacent left and right stepped pulleys 8.9. The rotor R is fitted onto the hollow support shaft 4, and a high frequency current is applied to the stator in order to rotate the rotor R. While the base 4 of the shaft and the protruding support shaft 2 are crimped to the middle of the left and right stepped pulleys 8.9 having larger diameters, the rotor R is also in contact with the rotor R. This allows it to rotate at extremely high speeds without causing any problems.

Therefore, there is a tape for rotating it,
Or, there is no need for a running body such as a belt, and as a result, it enhances the agility of the open-end spinning machine, and at the same time,
There is a significant effect that can be achieved by simplifying the mechanism.

FIG. 1 of the accompanying drawings shows an embodiment of the present invention for a single spindle in a known open-end spinning frame. In addition, Figure 2 shows a new open-end spinning machine with dual inner and outer rotors, or a method for increasing the speed of a twisting machine, etc.
The names of the elements or members shown in each drawing and the corresponding symbols are as follows.
