Therefore, even if a winder is enlarged and sped up, speedy yarn setting work can be performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spindle drive type yarn winding device, and more particularly to improvement of a spindle drive type yarn winding device provided with a forcibly driven roller bale.

[0002]

2. Description of the Related Art Generally, a spindle drive type winding machine is provided so that a roller bale is brought into contact with a winding layer formed on a bobbin mounted on a spindle, and the winding layer is not collapsed by the contact pressure of the roller bale. I am trying to arrange the shape. Further, by detecting the number of rotations of the roller bale, the drive source of the spindle is controlled so that the peripheral speed of the wound yarn layer is maintained constant.

In recent years, the spindle drive type winder has been increased in size and speed in order to improve productivity, and accordingly, the roller bale has also been increased in size and actively driven. However, when a yarn is wrapped around the roller bale due to a failure in thread switching or a break in the middle of the yarn, it is necessary to wait until the rotation of the roller bale stops before removing the yarn, and then performing the thread hooking work. As the size of the roller bale increases, the inertia of the roller bale increases, so that it takes 20 to 30 minutes before the roller bale stops, which causes a significant decrease in productivity.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a spindle drive type yarn winding device which enables a quick yarn hooking operation even if the winding machine becomes large in size and operates at high speed. .

[0005]

According to the present invention to achieve the above object, a forcibly driven spindle and a forcibly driven roller bale are installed in parallel, and the roller bale is wound on a bobbin mounted on the spindle. While contacting the thread layer,
In the spindle drive type yarn winding device adapted to move in the radial direction as the wound yarn layer grows, braking means is provided on the roller bale.

By thus providing the braking means on the roller bale, even when the roller bale of the winder becomes large and the inertia becomes large, the roller bale is shortened when the yarn breakage occurs or the yarn switching fails. It can be stopped in time and the thread hooking work can be done quickly. In the present invention, electric braking means is preferable as the braking means, and if the electric braking means is provided with a controller for supplying a regenerative current or a reverse phase current to the motor for driving the roller bale, it is compact. The configuration allows for a short outage. Further, it is preferable that the electric braking means by the controller is operated by a thread breakage detection signal provided with a thread breakage detector.

The present invention will be described below based on the embodiments shown in the drawings. 1 and 2 show a spindle drive type yarn winding device according to an embodiment of the present invention. In the figure, 1
Is a support box, 2 and 2 are a pair of spindles, and 3 is a roller bale. A turret board 4 is supported on the side surface of the support box 1, and the turret board 4 is placed around a horizontal rotation shaft (not shown)
It is designed to rotate intermittently by 80 °. A pair of spindles 2 and 2 are attached to the turret board 4 so as to extend horizontally at an interval of 180 ° with respect to the center of rotation, and an induction motor 5 for rotation drive is provided at each spindle end. 5 are connected.

Each of the pair of spindles 2 and 2 has 4
Each bobbin 6, ..., 6 is mounted, and the spindle 2 positioned on the upper side performs winding, and the spindle 2 positioned on the lower side is made to stand by for the next winding. The spindle 2 on the upper side (winding position) winds the yarn Y supplied from above onto the bobbin 6 while traversing the yarn Y laterally by the traverse device 8 to form a yarn layer 7 (package). When the winding layer 7 on the bobbin 6 at the winding position is fully wound, the turret board 4 is rotated by 180 ° so that the position of the spindle 2 on the standby side is switched and the yarn is switched.

The roller bale 3 is provided so as to face the bobbin 6 mounted on the spindle 2 at the winding position, and comes into contact with the winding layer 7 on the bobbin 6. The roller bale 3 has its shaft ends supported by the elevating box 10 via bearings 9 and 9, and has a drive induction motor 11 directly connected to one shaft end. The elevating box 10 is supported by the supporting box 1 so as to be movable up and down, and is moved upward together with the roller bale 3 as the winding layer 7 grows.

A speed sensor 12 for detecting the surface speed (winding speed) of the roller bale 3 is provided in the elevating box 10.
Is provided. The detection signal of the speed sensor 12 is sent to the controller 13, and the controller 13 controls the frequency of the inverter 14 based on the detection signal so that the surface speed of the winding layer 7 and the surface speed of the roller bale 3 are substantially. The induction motor 5 is driven so as to coincide with each other.

On the other hand, the induction motor 11 for driving the roller bale 3 has a controller 16 through an inverter 15.
Is connected. A thread break detector 17 and a setter 18 are connected to the controller 16, and when a thread breakage signal is input from the thread break detector 17, the regenerative current set by the setter 18 flows to the induction motor 11 and the roller bale 3 Is designed to brake.

As the braking control by the controller 16, the induction motor 11 may be switched to a reverse phase and braking may be performed by supplying a reverse phase current. Alternatively, both regenerative braking and anti-phase braking may be activated. That is, first apply a regenerative current to apply regenerative braking,
Next, control may be performed such that a reverse-phase current is passed to apply reverse-phase braking.

According to the winding device of the present invention, since the roller bale 3 is provided with the braking means as described above, when the yarn is wound around the roller bale 3 due to occurrence of yarn breakage or failure of yarn switching. First, the roller bale 3 is stopped by the operation of the braking means, the yarn is removed in a short time, and the next yarn hooking operation can be performed. For example, a bobbin with a total length of 1200 mm is mounted on the spindle, and the diameter is 9
When a winder equipped with a roller bale made of solid steel of 5 mm x 1250 mm in total length is operated at a winding speed of 6000 m / min, until the rotation of the free-running roller bale is stopped with a conventional winder. It takes about 20 to 30 minutes to wait, but with the winding machine of the present invention provided with the electric braking means, the wound yarn can be removed by stopping in about 5 minutes. Therefore, the next thread hooking operation can be performed within a short time after the occurrence of thread breakage or failure in thread switching, which can greatly contribute to improvement in productivity.

Further, since the braking means used in the present invention is an electric braking means, compared to mechanical braking means typified by a general disc brake, abrasion powder such as metal is not generated, so that the package is soiled. Can be prevented.

[0015]

As described above, in the spindle drive type yarn winding device of the present invention, by providing the driving type roller bale with the braking means, the roller bale becomes large and the inertia becomes large. Even if there is a yarn breakage or a yarn switching failure, the roller bale can be stopped in a short time, and a quick yarn hooking operation can be performed. Therefore, as a result, productivity can be significantly improved. In addition, product defects such as package dirt can be reduced.
