Abstract

PURPOSE:To wind up a superconductive wire material while the tension of the wire material is precisely made to be coincident with a set value, by comparing a measured tension of the superconductive wire material with a previously set value, and by moving a movable pulley in a direction in which the tension is increased, if the measured value is larger (smaller) than the previously set value. CONSTITUTION:A tension of a superconductive wire material 3 is measured by a load cell 11 and is compared with set value. Then, a movable pulley 5 which arranged between a supply drum 1 and a wind-up drum 2 is moved. Accordingly, the tension of the wire material 3 can be appropriately held always.

[Prior Art] In the coil winding process when manufacturing a superconducting magnet coil, it is necessary to wind the wire while applying tension to the wire. Conventionally, as shown in FIG. 2, fixed pulleys 4a and 4b and a movable pulley 5 are used to apply tension to the wire 3 with a weight 6, or as shown in FIG.
There is a method of applying tension to the wire rod 3 by applying a static torque with a brake 8 or the like and winding the wire rod 3 with a rotational torque exceeding that torque with the winding drum 2. In addition, in FIGS. 2 and 3, 7 is a brake mechanism, 9 is a current control electric circuit, and 10 is a control line.

In the case of the weight-type tension generator shown in FIG. 2, as long as the weight 6 has a constant load, only a constant tension can be obtained. If the wire rod 3 wound around the superconducting magnet coil can have a constant tension, the above device can be said to be the simplest and cheapest device. However, in the case of layered winding (pancake winding), it is necessary to reduce the tension each time the number of winding stages increases. It is necessary to adjust the brake mechanism 7 each time.

Further, in the method of applying a static torque to the supply drum 1 using the electromagnetic brake 8 as shown in FIG. 3, the tension can be adjusted relatively easily, but there is a problem that "torque-tension" is not achieved. In other words, with this method, truly accurate tension can be obtained by (1) changes in braking force due to wear of the electromagnetic brake, etc., and (2) changes in wire tension due to changes in the diameter of the wire wound around the supply tram. This is difficult and can only be used as an empirical guideline.
