Description

[Detailed Description of the Invention] The present invention relates to an improvement in the shape of the hook hanging hole of a discharge lamp ballast.

Generally, the assembled ballast is hung from a hook fixed to the support rod of the insulation treatment equipment, and is impregnated with insulation treatment agent stored in a tank etc. to improve the insulation effect. The hole for hooking the hook formed on the ballast is located at the base 1' of the ballast 1 as shown in Figures 1 and 2.
A hole 3 was formed in the circular hook adjacent to the mounting hole 2 to the main body of the instrument.

Therefore, the hook 4 and the hole 3 come into point contact when the stabilizer 1 is hooked on the hook 4, so there is a problem that the posture of the stabilizer 1 is difficult to stabilize.

Therefore, as an attempt to automate the production of ballasts, a plurality of ballasts 1 suspended from hooks 4 arranged horizontally on a support rod are placed on a drum or conveyor synchronized with the moving speed of the hooks 4 after insulation treatment is completed. Touch the suspended stabilizer 1 from below, control the support rod to change the height and direction of the hook 4, and turn the hook 4 so that the stabilizer 1 is horizontal, and hook it from the hole 3. When considering an automatic removal mechanism that pulls out the stabilizer, it is necessary to align the orientation of each stabilizer 1, otherwise they will not interact with each other when suspended from the hook 4 or automatically removed from the hook 4. This is not preferable because contact may lead to uneven varnish treatment, mutual adhesion due to varnish, etc., resulting in uneven quality, sloping in the process, etc.

In view of the drawbacks of the prior art described above, the present invention aims to stabilize the hanging posture of the stabilizer by changing the hole shape of the hook of the stabilizer.

Specific examples thereof will be described in detail below with reference to FIGS. 3 to 7.

3 and 4 show an embodiment of the present invention, and as shown in the figures, the hook 4 formed on the base 11 of the stabilizer 1 has a hole 3a having a triangular shape. , when the stabilizer 1 is suspended from the hook 4, the hook 4 is caught in the hole A of the hole 3a.

They are designed to touch at two points on the B side.

Therefore, the attitude of the stabilizer 1 is controlled within a narrow variation range in a certain direction, and the automatic removal mechanism can also perform the removal operation reliably and easily.

In addition, as shown in FIGS. 5 and 6, the hook is in the hole 3b.
, 3e are formed wide so that they are hung on the hook 4, it becomes easier to automate the work of hooking and removing the hook 4.

Further, as shown in FIG. 7, the hook hook can be formed so that the hook 4 contacts the hole 3d at three points, or can be contacted at more than three points.

As is clear from the above explanation, in the present invention, the hole shape of the hook hook is formed so that it contacts the hook at multiple points, so there is no variation in the hanging posture of the stabilizer, and moreover, the hook hook can be easily hooked to the hook. This makes removal work easier and is suitable for automated mechanisms.
