Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a hollow fiber winding device used by being loaded in a body fluid treatment device or the like.

[0002]

2. Description of the Related Art Conventionally, hollow fibers have been wound up on a polygonal drum or a flat plate, but when the winding speed of the hollow fibers is increased, the tension changes greatly and the hollow fibers break or break. The cracks and the like tended to occur and the performance of the yarn was likely to deteriorate. Therefore, the present inventor has arrived at the next invention as a result of extensive studies to solve the above problems.

[0003]

That is, the present invention provides a hollow fiber feeding means, a hollow fiber conveying means, a hollow fiber tension maintaining means, a hollow fiber feeding speed automatic control means, and a hollow fiber feeding means. The present invention provides a winding device including a winding means, a driving means for the feeding means and the winding means, and a control means for the respective means.

FIG. 1 is a schematic view of the winding device 1 of the present invention.
FIG. 2 is a right side view of FIG. The winding device 1 includes a feeding unit 8 as a hollow fiber feeding means, a guide roller-2 as a hollow fiber conveying means, and a gravity-type dancer roller-3 as a hollow fiber tension maintaining means. An optical sensor 4 for tension control as an automatic control means of the feeding speed of the hollow fiber, a take-up conveyor 5 as a take-up means of the hollow fiber, and a servo mechanism as a driving means of the feeding means and the take-up means. And a control box 7 as a control means for the above-mentioned means.

The feeding unit 8 is a hollow fiber raw roll 9
Is set, and the hollow fiber is fed out by the servo motor 6a in synchronization with the winding speed. The guide roller-2 is for carrying through the hollow fiber fed from the feeding unit 8. Gravity dancer
A weight 3a is attached to the roller 3, and the tension of the hollow fiber can be kept constant by controlling the feeding speed of the hollow fiber raw roll 9.

The tension controlling optical sensor 4 detects the position of the gravity type dancer roller 3 and automatically controls so that the feeding speed of the hollow fiber is within a certain range. The take-up conveyor 5 is, for example, a road yarn type conveyor-5a (a conveyor for winding a hollow fiber around the first yarn 12 and winding it) shown in FIG. 4, and a belt conveyor 5b shown in FIG. Can be used by fixing the tape with a tape 14 or the like and winding it up.

The servo motor 6a for the feeding means is attached to each hollow fiber raw roll, and the feeding speed is set so that the position of each gravity type dancer roller-3 falls within a certain range. To control. Take-up conveyor service
The controller 6b can be rotated by the set program.
Start (initial winding speed: 0 to 5 m / min) → high speed winding (linear speed: 1,000 to 1,700 m / min) →
This is a slow-down operation (final winding speed: 5 to 0 m / min) to wind a required amount.

Next, the operation method of the winding device 1 will be described with reference to FIG.
Will be described with reference to the block diagram of FIG. Slow start (initial winding speed: 0-5 m / min) → high-speed winding (linear speed: 1,0) according to the program set by the CPU
(00 to 1,700 m / min) → slow-down (final winding speed: 5 to 0 m / min), and at the speed set in the winding speed setting device 10 and the winding length setting device 11, Take up a specified length.

In order to feed each hollow fiber raw roll, the independent position of the dancer roller-3 is read by an optical sensor 4 for tension control, and the servo is controlled so that it is within a certain position range. It is controlled by the switch 6a.

[0010]

As described above, according to the present invention, almost no fluctuation in tension is generated, and abrupt fluctuations in linear velocity can be eliminated, and a uniform and high quality hollow fiber bundle can be manufactured, resulting in high performance and dispersion. A small body fluid treatment device can be manufactured. If the length between the winding rollers is set to be long, a larger number of hollow fiber bundles than one bundle can be removed without waste, and the slagging portion is almost eliminated, thereby reducing the cost. Winding is also completed in a linear form, enabling automation of post-processes such as "wrapping" and "bundle cutting".
