Abstract:
1. An electronic-component feeding device for feeding a plurality of chip-type electronic components, comprising: a pipe group being formed by a plurality of rectangular pipes arranged in parallel and in a high density, each of said rectangular pipes having an inner passage formed in conformity to an outer shape of said chip-type electronic component and allowing two or more of said chip-type electronic components to be aligned in a line along said inner passage; a component extraction portion formed in a first end of each rectangular pipe of said pipe group; and component feed means disposed at a second, opposite, end of each rectangular pipe of said pipe group, and adapted to feed the chip-type electronic component to a corresponding one of said component extraction portions wherein said component feed means comprises; a hopper group consisting of a plurality of hoppers each connected to a corresponding one of the second ends of said rectangular pipes, and adapted to store the chip-type electronic components in a bulk state; a hopper driven mechanism adapted to vertically move at least either one of said hopper group and each of said second ends of said rectangular pipes so as to supply the chip-type electronic components in said hopper group to each of the inner passages of said rectangular pipes; and shift means adapted to shift the chip-type electronic components in each of the inner passages of said rectangular pipes to a corresponding one of said component extraction portions; wherein said shift means is designed to supply positive pressure air intermittently, by synchronizing with the driving operation of said hopper drive mechanism, to said hopper group so as to shift the chip-type electronic components in each of the inner passages of said rectangular pipes to a corresponding one of said component extraction portions.
