A screw feeder adapted for rapid changeover of screw types. The feeder has a collator section having a floor with slots to collate random screws into rows and an enclosure about the floor for retaining random screws on the floor. The screws are collated by tilting the floor in the slotted direction to raise and lower the upstream end relative to the downstream end and are fed downstream along the slots into slots in a dispensing section. The collator section enclosure has a gate closure at the upstream end of the floor and the slots on the floor extend completely to the upstream end so that, with the gate open and the collator section oscillated to tilt the slots downward toward the upstream end, the screws in the slots will slide to the upstream end and out of the enclosure.
A tray to tube manual exchanger is disclosed herein. The manual exchanger includes a tray-fastening module and a bi-axle-rotating module. The tray-fastening module includes a tray-fastening member, a buffer-rail substrate, and a tube-inserting member. The buffer-rail substrate having a plurality of rails is disposed under the tray-fastening member, and the tube-inserting member is disposed at the outlets of the plurality of rails for respectively receiving tubes. The bi-axle-rotating module is pivotally connected to the tray-fastening module. The tray-fastening module clips a tray carrying a plurality of packaged semiconductor devices at a horizontal position, followed by rotating 180 degrees around a second rotating axle of the bi-axle-rotating module, thereby falling the packaged semiconductor devices of each row of the tray onto each rail. Subsequently, the tray-fastening module is inclined to a specified angle around a first rotating axle of the bi-axle-rotating module to make the packaged semiconductor devices of each rail slide into tubes inserted to the tube-inserting member.
Apparatus for handling and feeding of groups of fasteners such as screws to an applicator or applicators for applying workpieces such as hinges to a base at a series of worksites. A dispenser at a charging site receives from a fastener feeder a charge of the groups of fasteners needed at all of the worksites of the series and then moves consecutively to each of the worksites to dispense a group of fasteners to an applicator at each worksite. A plurality of passageways extend from a fastener receiving side at the top to a fastener discharge side at the bottom of the dispenser, one passageway for each fastener to be dispensed. The discharge ends of the passageways register with receiving apertures at the applicator at each site. A series of gates at positions along the passageways selective hold and release groups of fasteners at their respective positions.
