The present invention relates to a switch of a textile machine, and more particularly, to a switch for a textile machine such as a loom consisting of a switch member having a mechanical contact and an "actuator" member for operating the switch member. BACKGROUND OF THE INVENTION There are various methods for detecting the rotational phase of a rotating member in a textile machine. For example,

(A) A method of installing a "dog" for operating a switch on a rotating member and hitting the limit switch fixedly installed by the "dog".

(B) A method of installing a "dog" for operating a switch on a rotating member and operating a non-contact contact switch (so-called proximity switch) by the "dog".

(C) The "dog" may be made of magnets, and the reed switch may be operated by such magnets.

However, the method of (a) has a problem that the limit switch is always hit by the "dog" during operation of the textile machine such as a loom, so that the mechanical life of the limit switch is insufficient.

On the other hand, the method of (b) is preferable because the mechanical life is long and it is difficult to be affected by the privates received on the textile machine, but there is a problem that a special amplification device is required, the device is complicated, and the device cost is high. .

Also, in the method of (c), it is difficult to be affected by the editorial, etc., which accompanies the textile machine, as in the method of (b). There is a problem that the mechanical life of the reed switch is insufficient because it is operated by. In particular, a loom is a serious problem in a device that performs a high-speed winding such as a jet loom. The object of the present invention is to solve the problems associated with the conventional apparatus as described above, and to provide a switch of a textile machine having a relatively low structure cost and a long mechanical life due to a relatively simple structure.

Referring to the configuration of the subject innovation is as follows.

The present invention is a textile machine switch comprising a switch member having a mechanical contact and an "actuator" member for operating the switch member, wherein the relative position of the electrical switch member and the "actuator" member is movable. The above object is achieved by a switch for a textile machine that can selectively take a switch operating state and a switch non-operating state.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing examples of the present invention.

1 shows an embodiment in which the present invention is implemented to control the rotation of an auxiliary motor of a loom. A mechanical clutch member 10, 1 capable of engaging and disengaging a pair of engagement and disengagement between the primary shaft 11 and the driven shaft 12 is provided. . In other words, the clutch member 10 is integrally installed on the primary shaft 11, and the clutch member 1 is " spline " coupled to the axial direction of the driven shaft 12 on the other hand. The clutch member 1 is integrally formed with the tooth 4, and a groove is formed between the clutch member 1 and the tooth 4 in the circumferential direction, and the tip of the clutch shaft lever 7 is engaged with the groove.

The clutch shaft lever 7 is rotatable around the support shaft 13, and the other end is connected to the pneumatic cylinder 8, and the compressed air supplied to the pneumatic cylinder 8 has a shaft 4 of the driven shaft 12 along with the gear 4 in the clutch section. Direction to engage or disengage the clutch member 10 and the clutch member 1 from each other. In normal operation, the clutch member 10 and the clutch member 1 are engaged with each other as shown in FIG. 3 so that rotation of the main motor (not shown) is transmitted from the driving shaft 11 to the driven shaft 12 via the clutch member 10. On the other hand, during abnormal operation, as shown in FIG. 2, the clutch member 1 is separated from the clutch member 10, the gear 4 is engaged with the gear 5 mounted on the output shaft of the auxiliary motor 6, and the driven shaft 12 is connected to the auxiliary motor 6. It rotates via gear 4 and 5.

In this case reference numeral 2 is a magnet, which is one embodiment of the "actuator" member of the present invention.

In order to control the rotation of the auxiliary motor, a magnet 2 installed on the main surface of the clutch member 1 is installed, and the reed switch of the reed switch 3 fixed to the expected side by the magnet 2 is operated. Input signal 3 to control box 9.

In this embodiment, as shown in FIG. 2 and FIG. 3, the installation position of the jid switch 3 is not operated by the magnet 2 in the normal operation of the reed switch 3 (FIG. 3), and in the abnormal operation. 2 reliably takes the position (FIG. 2) which operates the reed switch 3 by magnetic force. As a result, since the reed switch 3 is operated by the magnet 2 only in abnormal operation, the life of the mechanical contact of the reed switch 3 is greatly extended.

A second embodiment of the present invention is shown in FIG. In this embodiment, the brake 14 is operated by the pneumatic cylinder 16, and the rotating member 15 is stopped at a predetermined angle position. The magnet 2 is projected on the main surface of the rotating member 15 and the reed relay of the reed switch 3 is operated by the magnet 2. It works.

In the embodiment shown in FIG. 4, the reed switch 3 is fixed to the lever 17 that can be rotated around the support shaft 18. As shown in FIG.

This lever 17 is normally separated from the rotating member 15 in the normal direction by the action of the spring 20. On the other hand, the reed switch 3 in which the electromagnetic solenoid 19 acts is positioned near the rotating member 15 so that the reed switch 3 is operated by the magnet 2 protruding on the main surface of the rotating member 15.

In this embodiment, in normal operation, the electronic solenoid 19 is turned off to separate the reed switch 3 from the rotating member 15 so that the reed switch 3 is not operated.

When the rotating member 15 is stopped, the solenoid 19 is turned on to place the reed switch 3 near the rotating member 15 to detect the magnet 2 protruding from the main surface of the rotating member 15 by the reed switch 3 and brake the pneumatic cylinder 16. 14 can be controlled to stop the rotating member 15 at a predetermined angle position. As a result, since the reed switch 3 is operated by the magnet 2 only at the stop, the life of the mechanical contact of the reed switch 3 is greatly extended.

Another embodiment of the present invention is shown in FIGS. 5 and 6, in the above-described embodiment, the reed switch 3 is installed to be movable, but in the present embodiment, the reed switch 3 is positioned at the expected side of the rotating member 15. It is fixed to the position and makes the magnet 2 mounted on the rotating member 15 movable. That is, the guide 22 or the like enables the magnet 2 to be movable in the radial direction of the rotating member 15, and the magnet 2 is pressed against the rotation center of the rotating member 15 by the spring 21. In the low speed rotation of the rotating member 15, the centrifugal force acting on the magnet 2 is small, and the magnet 2 is located on the central axis of rotation of the rotating member 15 by a spring 21.

On the other hand, when the rotating member 15 rotates at high speed, the magnet 2 moves radially outward from the center of the rotating member 15 against the spring force of the spring 21 by centrifugal force.

Therefore, when the reed switch 3 is desired to be operated by the magnet 2 only at low speed rotation of the rotating member 15 according to the function of the reed switch 3, as shown in FIG. Reed switch 3 is fixed near the center of rotation of rotating member 15 so as to

As a result, when the rotating member 15 rotates at high speed, the magnet 2 deviates from the reed switch 3, and thus the contact life of the reed switch 3 can be extended.

If the reed switch 3 is to be operated by the magnet 2 only when the rotating member 15 is rotated at high speed, the reed switch 3 is fixedly mounted away from the rotating member 15 during the high speed rotation so that the magnet 2 faces the reed switch 3. Let's do it.

Accordingly, when the rotational member 15 rotates at a low speed, the magnet 2 deviates from the reed switch 3, thereby extending the contact life of the reed switch 3.

The invention is relatively simple in structure, low in cost of equipment, long in mechanical life, and very suitable as a switch for a high speed winding device such as a textile machine, especially a loom.
