Abstract

PURPOSE:To apply bonding agent on a piece of wire uniformly, by turning a bonding-agent coater with the tension of the wire, aligning a die in the direction of the wire, thereby passing the wire without single-side touching with a die hole even if the angle of the wire is changed. CONSTITUTION:A piece of wire 5 is positioned with a positioning roller 10 in the vicinity of a tangential line with a winding core 1. Tension is applied to the wire 5 with a brake, and a driving motor is rotated. Then the winding core 1 is rotated, and the wire 5 is wound. With the wire 5 being wound around the winding core 1, the positioning roller 10 is moved at a suitable speed. Then the wire 5, on which a bonding agent 7 is applied, is positioned with the positioning roller 10. Thus the wire is wound. When the single side of the wire 5 is contacted with the hole of a die 16, a bonding-agent coater is turned with the tension of the wire 5. The direction of the hole of the die 16 is aligned with the angle of the wire 5. When the winding in the first layer is finished and the winding in the second layer is carried out, the bonding-agent coater is turned into the direction so as to eliminate single-side touching, by the tension of the wire. Thus the hole of the die 16 is aligned with the angle of the wire 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a superconducting magnet winding machine for winding a superconducting magnet by applying an adhesive to a wire.

[Conventional technology]

Figures 1 and 1 show how adhesive is applied in a conventional winding machine of this type. ) are combined. +71 is a driven bearing for supporting the winding core. The drive device (2) is provided with a drive motor (g). Adhesive is applied to the wound wire (5) with a brush (6). (7) shows the adhesive applied with a brush (6).

The wire 1s) of the superconducting magnet needs to be wound with a predetermined number of turns between predetermined dimensions, and the wires must be fixed together with an adhesive to prevent electromagnetic force.

The above conventional method of applying adhesive is to use a brush (6) with adhesive (wa) applied from the top of the wound wire (sl) to the multi-core wire (1).
Drive device (2), driven bearing (3), drive motor (4 =
1, manually rotate the winding core (1).
) was painted.

[Problem to be solved by the invention 3. The method of applying adhesive in conventional superconducting magnets as described above is not mechanized. In addition, the adhesive applied between the wires requires special adhesive to withstand extremely low temperatures. The problem was that it was difficult to spread between the wire rods due to its high viscosity. Therefore, in order to mechanize this process and ensure that the adhesive was completely applied between the wires, a method was adopted in which the wires were passed through a container containing the adhesive, the wires were dipped in adhesive, and the wires were wound up.

At this time, a die was provided at the outlet of the container to determine the amount of adhesive applied. A positioning roll is used to wind the wire while determining the position of the wire. For example, //
When changing the m-th and second layers, the operating direction of the positioning roll is reversed, and the angle of the wire before winding changes.
When the wire rod passing through the hole in the die has an unchanging positional relationship between the die and the positioning roll, it causes a one-sided contact 9 in the die, and (
al Adhesive is not applied uniformly to the wire.

(b) Depending on the hardness of the die, the wire may be damaged.

(cl The die wears out and the amount of adhesive attached to the wire increases.

There were problems such as:

” This invention was made to solve the above-mentioned problems, and allows the wire to pass through the die hole without unevenly touching the die hole even if the angle of the wire changes, and allows the adhesive to be applied uniformly to the wire. The object of the present invention is to obtain a winding machine for superconducting magnets that can be attached.

[Means for solving problems]

The winding machine for superconducting magnets according to the present invention includes a positioning roller for positioning a wire on a multicore winding, a positioning drive device for this positioning roller, and an adhesive container mounting plate on the center line of both of the side rollers. and a rotary shaft that rotatably supports the.

[For production]

In this invention, the path of the die is aligned with the center line connecting the rotating shaft and the positioning roller.

Even if the angle of the wire rod changes depending on the direction of movement of the positioning roll, the adhesive applicator rotates due to the tension of the wire rod, and the die is aligned in the direction of the wire rod, so that the wire rod is attached to the die without touching one piece. Go inside. At this time, the amount of adhesive applied to the wire is determined by the diameter of the die. Furthermore, when the diameter of the positioning roll decreases due to wear, and the angle of the wire changes, the adhesive applicator rotates as appropriate to change its posture.
