Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a supply device for ballasts that are assembled into lighting equipment, and in particular provides a supply device that is optimal for simultaneously supplying a plurality of ballasts during automatic assembly of lighting equipment. That is.

Generally, lighting equipment is equipped with a ballast. Usually, an appropriate number of ballasts are provided depending on the number of lamps attached to the lighting equipment. For example, a lighting fixture that is equipped with two annular fluorescent lamps, which is often used in general households, is a nearly cylindrical body with a bottom, two ballasts attached, two glow lamp sockets, and one safety lamp. A ball socket, a switch, etc. are installed, these parts are electrically connected to a ballast and a power line, and a reflector is attached, and a plurality of lamp holders are attached to the periphery of the reflector.

Conventionally, such annular fluorescent lamp lighting fixtures have been assembled by workers manually supplying and assembling each component on a suitable jig. As a result, workability was extremely poor and productivity was low.

Therefore, automatic assembly through mechanization is preferable to improve the productivity of lighting equipment, but automation has been difficult because it is difficult to direct parts when supplying them and to position each part relative to each other. In particular, this type of lighting equipment has a narrow component storage space in the equipment body, and the individual parts must be arranged efficiently.If multiple ballasts are installed, the arrangement is important. The supply direction and positioning were problems.

In view of the above-mentioned problems associated with the automation of the assembly of lighting equipment, this invention has been developed to improve and eliminate these problems.The ballast is positioned using positioning pin holes formed at both ends of the ballast frame. This is a ballast feeding device that holds the ballast in this position, transfers it, and feeds it onto the assembly jig, and is ideal for efficiently and automatically feeding multiple ballasts to predetermined positions. The present invention provides a supply device that provides a convenient supply system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a case where an embodiment of the present invention is applied to a lighting fixture equipped with two annular fluorescent lamps will be described with reference to the drawings.
