Abstract

The assembly of a typewriter requires repeated plugging and unplugging of the power cord during the assembly process at different work stations and test stands. In order to eliminate the need for repeated plugging and unplugging of the power cord and the elimination of the need for isolation transformer power supplies at each assembly and test bench, an isolation power supply may be incorporated into the carrier used on the conveyor system. The isolation power supply consists of a primary coil 1 mounted on the handling system or conveyor 2. A secondary coil 3 and power receptacle 4 are mounted in a non-metallic handling container 5. At the start of the assembly process, the typewriter line cord is plugged into receptacle 4 and can remain plugged during the entire assembly process.

Electrical Isolation Power Supply for Typewriter Assembly Conveyor Systems

The assembly of a typewriter requires repeated plugging and unplugging of the power cord during the assembly process at different work stations and test stands. In order to eliminate the need for repeated plugging and unplugging of the power cord and the elimination of the need for isolation transformer power supplies at each assembly and test bench, an isolation power supply may be incorporated into the carrier used on the conveyor system. The isolation power supply consists of a primary coil 1 mounted on the handling system or conveyor
2. A secondary coil 3 and power receptacle 4 are mounted in a non-metallic handling container 5. At the start of the assembly process, the typewriter line cord is plugged into receptacle 4 and can remain plugged during the entire assembly process. As handling container 5 is moved into a processing station, a sensing device 6 turns power on to the primary coil 1. The magnetic field created by the primary coil, pulls the secondary coil down, which is held up by bias springs 7, in contact with the primary coil and induces power through the secondary coil to power receptacle 4. When operation is completed, power is shut-off to the primary coil, the secondary coil's bias springs pull the coil back up, and the handling container can be moved to next station.
