Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to a spinning machine such as a ring spinning machine and a ring twisting machine, which is fitted to a lower portion of a ring to prevent a ring detachably fitted to a ring plate from coming off. The present invention relates to a ring fixing spring attaching / detaching tool used for attaching / detaching a ring fixing spring to be worn.

[Prior Art] In this type of spinning machine, in order to detachably fix the ring to the ring rail, the ring 3 is generally inserted into the fitting hole 2 formed in the ring plate 1 as shown in FIG. A ring fixing spring 5 is fitted in an annular locking groove 4 formed in the lower portion of the ring 3. Then, when the ring fixing spring 5 is attached to or detached from the ring 3, the worker holds the ring fixing spring 5 in a state of pushing it out against the spring force with a fingertip and inserts it into a predetermined position of the ring 3 or It was supposed to be removed from the specified position.

[Problems to be Solved by the Invention] If the number of ring fixing springs 5 is small, it is not a problem even if an operator pushes and expands the ring fixing springs 5 with his or her fingertips when attaching or detaching them. There is no. However, there are as many as 200 rings 3 on one side of the spinning machine, and the work of pushing and spreading a large number of ring fixing springs 5 with fingertips not only makes the operator's fingertips tired, but also causes fingertip pain and reduces work efficiency. There is an inconvenience to do.

In order to eliminate the above-mentioned inconvenience, Japanese Utility Model Publication No. 35-16024 discloses that, as shown in FIG. 5, annular portions 5a are formed at both ends of the ring fixing spring 5, and the annular portion is formed at the tip as shown in FIG. It is disclosed that the tool 7 having a pair of protrusions 6 corresponding to 5a is used to attach and detach the ring fixing spring 5 to and from the ring. However, in this case, there is a problem that machining of the ring fixing spring 5 becomes troublesome.

The present invention has been made in view of the above problems,
An object of the present invention is to provide a ring fixing spring attachment / detachment tool for a spinning machine, which facilitates attachment / detachment of the ring fixing spring to / from the ring when a ring fixing spring that is easy to process is used.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, a pair of opening / closing members including an operating portion and an operating arm portion extending in opposite directions with respect to a rotation center are made rotatable. An engaging groove engageable with an end portion of a ring fixing spring, which is attached to a shaft and serves to prevent the ring from slipping out and inserted into the ring plate, is provided outside the operating portions of the opening and closing members, and extends from the tip end to the base end. Was formed so as to extend.

[Operation] The tool of the present invention is operated by gripping the operation arm.
The action part is opened and closed. When the action portion is opened with both ends of the ring fixing spring engaged with the engagement grooves formed on the outer sides of the pair of action portions, the ring fixing spring is expanded. Also, when the action portion is closed, the ring fixing spring returns to its original state due to its spring force.

[Embodiment] An embodiment embodying the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the tool 7 is rotatably mounted with a pair of opening / closing members 10 each including an operating portion 8 and an operating arm portion 9 extending in opposite directions with respect to the center of rotation. Engagement grooves 11 extending from the distal ends toward the proximal ends are formed on the outer sides of the action portions 8 of both the opening and closing members. In addition, both operating arms 9
A compression spring 12 is attached to the inner side of each of the opening / closing members 10, so that both opening / closing members 10 are always held in a state in which both acting members 11 are closed.

As shown in FIG. 2, the ring fixing spring 5 is formed by bending a wire made of spring steel into a substantially triangular shape so that the wire comes into contact with the ring at three points, and its both ends are slightly bent so that the locking portion is formed. 5b is formed.

When the work for attaching the ring fixing spring 5 to the ring 3 is performed, the operating arm portion 9 of the tool 7 is held by one hand and the acting portion 8 is inserted between the both locking portions 5b of the ring fixing spring 5. At the same time, the operating arm 9 is compressed with a compression spring.
Tighten against 12 spring forces. As a result, the action portion 8 of the tool 7 is opened and the engaging groove of the action portion 8 is opened during the opening.
The locking portion 5b of the ring fixing spring 5 engages with 11, and the ring fixing spring 5 is pushed and spread against the spring force as the acting portion 8 is opened. As shown in FIG. 3 in a state where the ring fixing spring 5 is expanded, the ring fixing spring 5 is fitted into the ring plate 1 and is fitted into a predetermined position of the ring 3 protruding to the back side of the ring plate 1,
At that position, the grip force of the operation arm portion 9 is relaxed. When the gripping force is released, the opening / closing member 10 is rotated by the spring force of the compression spring 12 in the direction in which the action portion 8 is closed, and the action portion 8 is closed, and the engagement groove 11 and the engagement portion 5b of the ring fixing spring 5 are engaged. Is canceled. Then, the ring fixing spring 5 is fitted into a locking groove (not shown) of the ring 3. Also, when removing the ring fixing spring 5 fitted to the ring 3, the operating arm portion 9 is operated in the same manner as described above to push and expand the ring fixing spring 5 to release the fitting state with the ring 3. , Can be removed from the ring 3.

The present invention is not limited to the above embodiment,
For example, the compression spring 12 may be omitted, and the operator may perform both the opening and closing operations of the opening / closing member 10. Alternatively, the action portion 8 in which the engaging groove 11 is formed may be formed as a separate member to form the opening / closing member 10. It may be configured to be detachably attached with a screw.

[Effects of the Invention] As described in detail above, by using the tool of the present invention, it becomes easy to attach and detach the ring fixing spring to and from the ring fitted in the ring plate, and the end portion of the ring fixing spring is made special. It has an excellent effect that the conventional ring fixing spring can be used as it is without having to process it into a shape.
