Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is a rotary rail changer that is disposed at a corresponding disconnection between a first rail and a second rail running in parallel to switch the track between the two rails. It relates to a warping machine, and is used, for example, to change the track of a rail that guides and supports a cassette creel used in a warping machine.

(Prior Art) As the track switching device at the discontinuous portion of both rails, it is easy to consider adopting a conventionally used slide type rail changer.

FIG. 6 shows an example of this, in which three types of connection rails b, c, and d are arranged on a slide stand a, and when the slide stand a is located at the position shown in the figure, the first rail The respective disconnected portions of the rails e and the second rails f are connected by a first connecting rail (rail pair) b. On the other hand, by sliding the slide table a in the V direction and setting the position, the first rail e
One broken end g of the second rail f and the other broken end h of the second rail f can be connected by the second connecting rail c, and by sliding the slide platform a in the W direction to set the position, the second rail f can be connected to the other broken end g of the second rail f. One broken end i and the other broken end j of the first rail e are connected to a third connecting rail d.

When set in the connection position shown in Figure a, the first rail 7
and the second rail 8 are each connected to a pair of connecting rails 2
1 and 21. Moreover, when the second surface of the rotor 20 is set at the connection position shown in FIG. 2b,
One broken end 7g of the first rail 7 and the second rail 8
is connected to the other disconnected end 8h by a connecting rail 22. Furthermore, when the third surface of the rotor 20 is set to the position shown in FIG. .

The switching of the connection rails described above is performed using the rotor 20.
This is done quickly by the rotation of the According to this rotary type rail changer, the width of the rotor 20 can be set to be approximately the same as the spacing between the first rail 7 and the second rail 8, and the width of the rotor 20 can be set to be approximately the same as the distance between the first rail 7 and the second rail 8, and the width of the rotor 20 can be set to be approximately the same as the spacing between the first rail 7 and the second rail 8. Space can be significantly reduced.
