  • Component feeding system
    Patent number: 5729892
    Abstract: A first printed board transferred from a prior process on an inlet conveyer is placed on a moving unit at a first switching position. The moving unit moves to a second switching position while mounting the first printed board with electronic components from a component feeding section. During this process, a second printed board stands by at the second switching position via the inlet conveyer, a transit path and an intermediate conveyer. At the second switching position, the second printed board is placed on the moving unit while shunting out the first printed board onto an outlet conveyer for transfer to a subsequent process. The moving unit moves to the first switching position while mounting the second printed board with the electronic components from the component feeding section.
