Abstract

PROBLEM TO BE SOLVED: To reduce the feed time for electronic components to improve the production efficiency by feeding the components directly to an electronic component-mounting machine from a tray pallet and transferring them one by one to a take-up shaft to feed to the mounting machine. SOLUTION: A tray pallet-housing case 17 is lifted up by a lifting means to the height of tray pallet drawers 3, 4, a tray pallet 11 is drawn out to the tray pallet drawer 3 by a drawing unit to directly chuck electronic components from the pallet 11 through a chucking unit 7 mounted on a take-up shaft 5 of an electronic component-mounting machine. The components are transferred onto an electronic component-mounting unit 9 moving on an electronic component-transfer unit 6 and carried to a chucking position 2 at the end of the transfer unit 6, thereby enabling the supplement/replacement of electronic components. Thus electronic components mounted on the pallet 11 can be efficiently fed.
