Title:
IMPROVED FEEDER FOR ELECTRICAL COMPONENT FEEDING TAPE
Document Type and Number:
Japanese Patent JPS6486598
Kind Code:
A
Abstract:
PURPOSE: To prevent a part from falling from an open pocket by covering the pocket with a shutter during movement of a tape and opening a pickup region by moving the shutter after each index step thereby giving access to a part in the pocket. CONSTITUTION: When a drive link turns clockwise, a drive roller 52 rides over the cam of a shutter litter to lift a shutter 74 in the direction receding from a tape 2. The drive roller 52 is engaged with the surface 62 of a shutter link 60 which is thereby turned clockwise and a shutter arm 70 is displaced from a pickup region. Consequently, the motion of a shutter 74 entirely takes place before the tape 2 is advanced. The tape 2 is advanced only when the shutter 74 is located above the pickup region and when the tape 2 is advanced by one index step, the pocket 6 of the tape passes underside of the shutter 74 with an upper cover 8 being stripped from the pocket 6. Consequently, a part is held constantly in the pocket when the tape is advancing and when the pocked is opened.
