Description

TECHNICAL FIELD The present invention relates to a continuous impregnation apparatus with a hanger horizontal mechanism.

[Prior Art and Problems Thereof] Varnish impregnation of electric equipment coils such as transformers and stator coils is shifting from batch impregnation to highly efficient continuous impregnation. However, in the case of continuous impregnation treatment, all the steps are automated, so that so-called high impregnation accuracy in millimeter units cannot be obtained. Therefore, continuous impregnation treatment is not adopted for electric equipment coils, such as transformers with pins and stator coils with terminals, which are particularly susceptible to adhesion of varnish to varnish-free portions because high impregnation accuracy is required. In order to solve this problem, attempts have been made to improve the shape accuracy of the hanger that holds the object to be processed of the continuous impregnation processing apparatus, or adjust the rising speed of the impregnation tank to increase the impregnation accuracy. However, in any case, if the hanger immersed in the varnish liquid in the impregnation tank loses the horizontal state, there is a problem that a high impregnation accuracy in millimeter units cannot be obtained at all. In particular, the horizontal state of the hanger greatly depends on the arrangement state of the object to be processed even if the shape accuracy of the hanger is increased. Moreover, if the object to be processed is arranged while always keeping the hanger in a horizontal state, there is a problem that workability is extremely deteriorated.

[Means for solving problems]

The present invention relates to an impregnation tank that opens the above to accommodate a varnish solution, an elevator that moves the impregnation tank up and down, a hanger locking rod provided above the impregnation tank, and a floor on which a target object is placed. And a horizontal plate protruding from the engaging arm, the hanger being suspended by engaging the engaging part of the engaging arm erected on the mounting floor with the hanger engaging rod. The horizontal impregnation device with a hanger horizontal mechanism, which is provided below the horizontal plate so as to be able to move up and down, and has a horizontality adjusting plate that abuts against the horizontal plate, and an elevating function of the horizontality adjusting plate.

[Action]

According to the continuous impregnation apparatus with a hanger horizontal mechanism according to the present invention, just before immersing the hanger whose level is lost with all the objects to be treated placed in the impregnation tank, the horizontal level of the horizontal plate protruding from the hanger is The horizontal state of the hanger is restored by abutting the adjusting plate.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an embodiment of the present invention, and FIG.
It is a side view of the same Example. In the figure, 1 is an impregnation tank filled with the varnish solution 2. The upper part of the impregnation tank 1 has an opening so that a hanger 4 (described later) holding the object to be processed 3 can be immersed in the varnish solution 2. The impregnation tank 1 is provided with a receiving portion 5 for receiving the overflowed varnish liquid 2 by immersing the object 3 in the varnish liquid 2 and only its volume. The impregnation tank 1 is placed on an elevator 6 and is moved up and down. Above the impregnation tank 1, a hanger 4 that holds the object 3 to be processed is placed on the floor. The hanger 4 is suspended by engaging an engaging portion of an engaging arm 7 which is erected on the mounting floor with a hanger engaging rod 8. A horizontal plate 9 is provided on the outer surface of the engagement arm 7 so as to project therefrom. Below the horizontal plate 9, a horizontal degree adjusting plate 10 that abuts against the horizontal plate 9 is provided so as to be movable up and down by an elevator mechanism (not shown).

Continuous impregnation device with hanger horizontal mechanism configured in this way
According to FIG. 20 , as shown in FIG. 3 (A), even if a plurality of objects 3 to be processed are placed on the floor of the hanger 4 and the hanger 4 loses its horizontal state, FIG. 3 (B) As shown in FIG. 6, by raising the horizontal degree adjusting plate 10 and abutting the horizontal plate 9 against each other, the horizontal state of the hanger 4 can be correctly set immediately before the impregnation process. For this reason, the hanger 4 holding the object 3 to be processed is always immersed in the varnish liquid 2 while keeping the predetermined horizontal state without the shape accuracy of the hanger 4 affecting the arrangement state area of the object 3. You can For this reason, it is possible to control the ratio of the object 3 to be dipped in the varnish liquid 2 very accurately and perform the impregnation treatment in millimeter units. As a result, it is possible to perform continuous impregnation of the varnish on the coil of electric equipment such as a pin type transformer with high accuracy and significantly improve the productivity.

〔The invention's effect〕

As described above, according to the continuous impregnation device with the hanger horizontal mechanism according to the present invention, the varnish impregnation treatment can be performed with a high impregnation accuracy of millimeter unit without being influenced by the mounting state of the object to be treated on the hanger. It is possible.
