Abstract

A technique is described whereby a fixture automatically unloads finished print wheels and packs them into cartons or sends them to required assembly areas. It also provides a method of transporting reject parts. The fixture provides four distinct functions: Function 1 - Removes rejected print wheels. Function 2 - Unloads accepted print wheels from an inline machine to a rotary buffer. Function 3 - If print wheels are needed in printer assembly operations, it unloads accepted print wheels and places them on a vibratory linear feeder track. Function 4 - Loads finished print wheels into single cartons as required. The fixture consists of the following units: 1.Pick and place device with a rotating vacuum head. 2.

Fixture to Automatically Unload and Pack Finished Print Wheel Assemblies

A technique is described whereby a fixture automatically unloads finished print wheels and packs them into cartons or sends them to required assembly areas. It also provides a method of transporting reject parts. The fixture provides four distinct functions: Function 1 - Removes rejected print wheels.

Function 2 - Unloads accepted print wheels from an inline

machine to a rotary buffer.

Function 3 - If print wheels are needed in printer assembly

operations, it unloads accepted print wheels and places them

on a vibratory linear feeder track.

Function 4 - Loads finished print wheels into single cartons

as required. The fixture consists of the following units:
1.Pick and place device with a rotating vacuum head. 2. Motorized conveyor belt mounted to a conveyor linear air operated transporter. 3. Proximity sensor for reading the flag on the fixture. 4. Rotary turret buffer with six holding fixtures

mounted on 60o center lines. Turret is mounted to the

base of an inline assembly machine. 5. Vibratory linear conveyor for removing parts that are diverted to printer assembly areas. 6. Pick and place head with equalizing mechanical clamping jaws mounted to the fixed center plate of the rotary

table buffer. 7. A stand-alone automatic single carton packer mounted

adjacent to the rotary table buffer. The automatic operation takes place on an inline assembly machine equipped with forty-two fixtures spaced on twelve-inch centers. The fixtures are indexed by an over- and under-conveyor system. As the fixture is indexed into a station position, a proximity sensor senses a flag located on the fixture. If the flag has been set in any previous station due to a fault, the flag will be picked up by the proximity sensor indicating a reject part is at the station. A pick and place head equipped with a 90o rotating vacuum head advances downward to pick up the part from the fixture. However, the rotating vacuum head does not rotate when a reject part was indicated. The motorized conveyor assembly is moved forward by the air-operated conveyor transport and positions itself under the retracted vacu...
