Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for attaching and detaching a ring holder to and from a ring rail.

[Prior Art] In a ring spinning machine and a ring twisting machine, a ring holder in which a ring is fitted is fixed on a ring rail. When removing and replacing the ring fitted in the ring holder due to wear or other reasons, first remove the ring holder with the ring still fitted from the ring rail, and then remove the ring from the ring holder. Is normal.

For fixing the ring holder to the ring rail, for example, as shown in Japanese Patent Publication No. 26-948, it is common to use at least two screws for each ring holder and screw the ring holder to the ring rail. . Therefore, it is necessary to rotate a large number of screws when performing simultaneous replacement of all rings for one spinning machine or twisting machine, and after removing the ring holder from the ring rail, removing the ring from the ring holder. Not only is it necessary to attach a new ring to the ring holder and to attach the ring holder to the ring rail, the ring centering adjustment work for the ring holder and the ring holder centering adjustment work for the ring rail are also required. A great deal of labor was added, and it took a long time to replace, which was extremely inefficient.

As a means to improve such problems, Japanese Examined Patent Publication No. 63-54811
As shown in No. 6, the ring holder fitted with the ring is horizontally rotated on the ring rail about the center axis of the ring, and the ring holder and the ring rail are rotated with respect to the rotationally symmetrical position about the center axis. There is a structure in which the ring holder is attached to and detached from a plurality of engaging means installed over the ring rail, and the ring holder is attached to the ring rail or detached from the ring rail. Depending on the direction of rotation of the traveler traveling on the vehicle, loosening may occur due to the influence of the frictional force between the traveler and the ring.

[Problems to be solved by the device]

An object of the present invention is to provide a device for attaching / detaching a ring holder to / from a ring rail in which the attachment / detachment of the ring holder to / from the ring rail can be performed with one touch, and even if the ring holder does not loosen after being fixed once.

[Means for Solving the Problems]

A ring holder having a concave groove on the peripheral surface of the pin tip protruding from the bottom surface and a fitting insertion hole for closely fitting the pin tip of the ring holder are provided, and a part of the spherical surface is formed by the biasing force of the spring. A ring rail provided with an engaging member made of a steel ball facing the fitting hole, the pin tip of the ring holder is press-fitted into the fitting hole of the ring rail, and the steel ball is inserted into the groove of the ring holder. Was inserted into the groove to release the steel ball from the groove by the pulling force, and the two pieces were separated from each other.

[Action]

When fixing the ring holder to the ring rail, align the tip of the pin with the fitting hole of the ring rail and pressurize the ring holder firmly to firmly fix it. Also, remove the ring holder from the ring rail. At this time, they can be separated by strongly separating them.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show the first embodiment of the ring holder attaching / detaching device of the present invention.
FIG. 3 is a diagram showing an embodiment of the present invention, in which a pin 3 is screwed into a screw hole 2 provided in a ring holder 1. The tip of the pin 3 penetrates the ring holder 1 and projects to the bottom surface, and a concave groove 5 whose groove surface is curved in an arc shape is formed on the peripheral surface of the tip portion 4.

On the other hand, on the ring rail 6 to which the ring holder 1 is fixed, a fitting insertion hole 7 into which the tip portion 4 of the pin 3 screwed into the ring holder 1 is densely inserted, and the fitting insertion hole 7 are orthogonal to each other. An engaging member 12 having a spring 11 interposed between two steel balls 9 and 10 is provided in the hole 8 to be formed, and one steel ball 9 is urged by the urging force of the spring 11.
It is formed so that a part of its spherical surface faces the fitting insertion hole 7.

Therefore, when fixing the ring holder 1 to the ring rail 6, the tip 4 of the pin 3 is made to match the fitting hole 7 of the ring rail 6 and the ring holder 1 is strongly pressed.
Is once pushed back by the peripheral surface of the tip portion 4 of the pin 3 and temporarily retracts into the hole 8 against the biasing force of the spring 11, and then springs in the groove 5 provided on the peripheral surface of the tip portion 4 of the pin 3. The ring holder 1 is firmly fixed on the ring rail 6 by being projected and fitted by the urging force of 11.

Further, when the ring holder 1 is removed from the ring rail 6, the steel balls 9 projectingly fitted into the concave groove 5 are pressed by the peripheral surface of the tip end portion 4 of the pin 3 by strongly separating them from each other.
The ring holder 1 can be easily removed from the ring rail 6 because it retracts into the hole 8 against the biasing force of the spring 11 and disengages from the groove 5.

In the first embodiment, the ring holder 1 is described as the one in which the pin 3 is screwed into the screw hole provided in the ring holder 1. However, as shown as the second embodiment in FIG. Even if a tip portion 4a having the same shape as the tip portion 4 is integrally formed as a part of the ring holder 1, or as shown as a third embodiment in FIG. 5, a tip portion having the same shape as the tip portion 4 of the pin 3 is formed. It is permissible to screw the pin 3a provided with 4b from the bottom side of the ring holder 1, and the engagement member 12 provided on the ring rail 6 also has a spring as shown in FIG.
One end of 11a is locked to the wall surface of the hole 8 formed in the ring rail 6, the other end is provided with a steel ball 9a, and a part of the spherical surface of the steel ball 9a is exposed to the fitting insertion hole. May be.

[Effect of device]

As described in detail above, the ring holder attaching / detaching device of the present invention is a ring holder having a concave groove on the peripheral surface of the pin tip protruding from the bottom surface, and a fitting insert for closely fitting the pin tip of the ring holder. A ring rail provided with an engaging member made of a steel ball having a hole, and a spherical surface of which faces the fitting insertion hole by a biasing force of a spring. Since it is press-fitted into the fitting insertion hole, the steel ball is fitted into the groove of the ring holder to fix them, the fitting of the steel ball into the groove is released by the pulling force, and both are separated. When fixing the ring holder to the ring rail, align the tip of the pin with the fitting hole of the ring rail and pressurize the ring holder firmly to firmly fix it. Also, remove the ring holder from the ring rail. Since they can be separated by strongly pulling them apart, it is possible to easily attach and detach with a single touch in an extremely short time, and many screws can be attached while requiring precise centering as in the past. It does not require a great deal of labor such as turning, installation and removal, and the stop time for ring maintenance of the ring spinning machine and the ring twisting machine can be greatly shortened. Further, since the ring holder is pressed and fixed from the direction perpendicular to the ring rail, the ring holder may be loosened regardless of whether the traveler traveling on the ring rotates counterclockwise or clockwise. It has excellent characteristics such as "no".
