Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement in a power supply and a transmission part formed by a slip ring and a brush for supplying electric power or transmitting a rotation speed signal in a turret type winder. It is a thing.

(Prior Art and Problems Thereof) Generally, in a synthetic fiber yarn spun from a spinning machine, a turret board 2 having spindles 4a and 4b for bobbin mounting as shown in FIG. Power is supplied to a rotary shaft 3 that is freely mounted and is integrally attached to the turret board 2, and power is supplied to an electric motor installed in the spindle through a transmission unit 5, and a rotation speed detector 6a, A turret type winder configured to transmit the signal from 6b to the control device 7 is used.

Then, the conventional power supply / transmission unit 5 has, for example, slips necessary for power supply to the spindle driving electric motor, power supply to the turret disc turning device, transmission of a detection signal from the rotation speed detector, and the like. A ring and a brush are installed, and as shown in detail in FIG. 4, a slip ring 9 is attached to the rotary shaft 3 via an insulating ring 8 and a brush 21 is attached to the machine casing 1. It is movably mounted on the frame body 20 and is brought into contact with the peripheral surface of the slip ring 9 by a spring 22 with a predetermined surface pressure. or,
The slip ring 9 has a conductor 14 whose end is connected to an electric motor (not shown) and a terminal of the rotation speed detector 6, and the brush 21 has a conductor connected to a terminal of the controller 7 at one end.
23 are connected respectively. One brush 21 is installed for each slip ring 9.

Therefore, if the brush is damaged, or the vibration generated during the winding operation exceeds the allowable vibration amount of the spring, contact failure will occur temporarily and power supply will be interrupted, or the detected rotation speed There is a problem that a signal cannot be transmitted and accurate rotation control cannot be performed.

(Purpose) An object of the present invention is to solve the above-mentioned problems and to reliably transmit electric power, a detection signal, or the like even when vibration occurs in the winder.

(Means for Solving Problems) The turret-type winder of the present invention slips power supply to an electric motor for driving a spindle rotatably mounted on a turret board and / or transmission of a rotation speed signal of the spindle. In a winding machine using a ring and a brush, a plurality of slip rings are attached to the rotary shaft of the turret board, and a plurality of brushes having different contact pressures are arranged on each slip ring.

(Embodiment) 1 of the power feeding and transmitting section in the turret type winder of the present invention
The configuration of the embodiment will be described with reference to FIGS. 2 and 3.

A brush 11 is movably mounted on a frame body 10 mounted on the machine frame 1, and two brushes 11 are installed on one slip ring 9 mounted on the rotating shaft 3 via an insulating ring 8. Has been done. Then, each brush 11 is brought into contact with the peripheral surface of the slip ring 9 by springs 12 and 13 having different pressing forces. Further, the brush 11 is connected to a conductor 15 whose end is connected to the control device 7.

(Effect of the Invention) The turret type winder of the present invention supplies power to an electric motor for driving a spindle rotatably mounted on a turret board and / or transmits a rotation speed signal of the spindle through a slip ring and a brush. In the winder to be carried out as described above, a plurality of slip rings are attached to the rotary shaft of the turret board, and a plurality of brushes having different contact pressures are arranged on each slip ring. Even if vibration occurs, it is possible to prevent contact failure of all the brushes that are in contact with one slip ring at the same time, and it is possible to reliably supply power or transmit a signal.
