Systems and methods for handling multiple container types

A rotary container starwheel comprising:

• a. an upper starwheel;
• b. a lower starwheel;
• c. one or more self-adjusting v-shaped container supports radially adjustable to accommodate differing container diameters;
• and
• d. one or more grabber arms, each of said grabber arms comprising:
• i. a leading grabber and a trailing grabber having mating spur gears formed there between configured to coordinate movement of the leading grabber with the trailing grabber;
• ii. a spring configured to actuate the grabber arm to a closed, container grabbing position;
• and
• iii. a fixed mechanical cam comprised of a cam wheel having one or more cam lift surfaces configured to contact any one of the leading or trailing grabber arms to actuate opening of the grabber arms.

A rotary multi-feed can lid assembly comprising;

• a. a series of vertical can lid silos
• b. an upper rotating indexing plate configured to rotatably support each vertical silo in an indexing hole formed on the upper rotating indexing plate;
• c. one or more spring loaded ball detents affixed to rotate with the upper rotating indexing plate on a pivot bearing;
• and
• d. a fixed lower indexing plate, positioned between the upper rotating indexing plate and a lid dispenser;
• said fixed lower indexing plate formed with a series of indents, aligned radially with the ball detents to allow extension of the spring loaded ball detents as the ball detents rotate with the upper rotating indexing plate, such that when the ball detent extends into the recesses, then one of the can lid silos are aligned with a single hole machined in the fixed lower indexing plate such that can lids can pass through the lower plate to the lid dispenser.

A system for processing a stream of multiple container types, said system comprising:

• a. an indexing assembly comprising:
• an indexing wheel;
• a conveyor chain configured for receiving a stream of multiple container types from the indexing wheel;
• and a series of container indexing arms arranged for movement with the conveyor chain, said container indexing arms each configured for indexing a container by its centerline, wherein each of said indexing wheel, conveyor chain and series of container indexing arms are arranged having a fixed spatial relationship to one another other at linear and non-linear speeds;
• b. a first starwheel, for receiving the stream of multiple container types from the indexing assembly, said starwheel comprising:
• an upper starwheel;
• a lower starwheel;
• one or more self-adjusting v-shaped container supports radially adjustable to accommodate differing container diameters;
• and one or more grabber arms, each of said grabber arms comprising:
• i) a leading grabber and a trailing grabber having mating spur gears formed there between configured to coordinate movement of the leading grabber with the trailing grabber;
• ii) a spring configured to actuate the grabber arm to a closed, container grabbing position;
• and iii.) a fixed mechanical cam comprised of a cam wheel having one or more cam lift surfaces configured to contact any one of the leading or trailing grabber arms to actuate opening of the grabber arms;
• c. a filling machine for receiving the stream of multiple container types from the first starwheel and filling the stream of multiple container types;
• d. a second starwheel positioned at an outfeed to the filling machine for receiving the stream of filled, multiple container types;
• e. a multi-feed can lid assembly, for receiving cans of the stream of filled, multiple container types from the second starwheel for applying can lids to the can;
• the multi-feed can lid assembly comprising:
• a series of vertical can lid silos;
• an upper rotating indexing plate configured to rotatably support each vertical silo in an indexing hole formed on the upper rotating indexing plate;
• one or more spring loaded ball detents affixed to rotate with the upper rotating indexing plate on a pivot bearing;
• and a fixed lower indexing plate, positioned between the upper rotating indexing plate and a lid dispenser;
• said fixed lower indexing plate formed with a series of indents, aligned radially with the ball detents to allow extension of the spring loaded ball detents as the ball detents rotate with the upper rotating indexing plate, such that when the ball detent extends into the recesses, then one of the can lid silos are aligned with a single hole machined in the fixed lower indexing plate such that can lids can pass through the lower plate to the lid dispenser;
• f. a universal closing turret, for receiving cans from the multi-feed can lid assembly and for receiving remaining types of containers from the second starwheel, said universal closing turret comprising multiple, varying closure applicators for different types of containers including cans and bottles, removably connectable to the turret to allow rearrangement of an order of closure applicators based on an order of types of containers to be closed, wherein the closure applicators are for closures selected from can lids, crimped crown closures, screw cap style closures and combinations thereof;
• and
• g. a third starwheel, positioned at an outfeed to the filling machine for receiving the stream of filled, closed multiple container types.

A method for processing a stream of multiple container types, said method comprising the steps of:

• a. feeding a stream of multiple container types to an indexing assembly comprising:
• an indexing wheel;
• a conveyor chain configured for receiving a stream of multiple container types from the indexing wheel;
• and a series of container indexing arms arranged for movement with the conveyor chain, said container indexing arms each configured for indexing a container by its centerline, wherein each of said indexing wheel, conveyor chain and series of container indexing arms are arranged having a fixed spatial relationship to one another other at linear and non-linear speeds;
• b. feeding the stream from the indexing assembly to a filler machine by a first starwheel comprising:
• an upper starwheel;
• a lower starwheel;
• one or more self-adjusting v-shaped container supports radially adjustable to accommodate differing container diameters;
• and one or more grabber arms, each of said grabber arms comprising:
• i) a leading grabber and a trailing grabber having mating spur gears formed there between configured to coordinate movement of the leading grabber with the trailing grabber;
• ii) a spring configured to actuate the grabber arm to a closed, container grabbing position;
• and iii.) a fixed mechanical cam comprised of a cam wheel having one or more cam lift surfaces configured to contact any one of the leading or trailing grabber arms to actuate opening of the grabber arms;
• c. filling the stream of multiple container types;
• d. receiving the filled, stream of multiple container types by a second starwheel, and feeding cans of the filled, stream of multiple container types to a multi-feed can lid assembly comprising:
• a series of vertical can lid silos;
• an upper rotating indexing plate configured to rotatably support each vertical silo in an indexing hole formed on the upper rotating indexing plate;
• one or more spring loaded ball detents affixed to rotate with the upper rotating indexing plate on a pivot bearing;
• and a fixed lower indexing plate, positioned between the upper rotating indexing plate and a lid dispenser;
• said fixed lower indexing plate formed with a series of indents, aligned radially with the ball detents to allow extension of the spring loaded ball detents as the ball detents rotate with the upper rotating indexing plate, such that when the ball detent extends into the recesses, then one of the can lid silos are aligned with a single hole machined in the fixed lower indexing plate such that can lids can pass through the lower plate to the lid dispenser;
• e. feeding cans from the multi-feed can lid assembly and a remaining stream of multiple container types from the second starwheel to a universal closing turret comprising multiple, varying closure applicators for different types of containers including cans and bottles, removably connectable to the turret to allow rearrangement of an order of closure applicators based on an order of types of containers to be closed, wherein the closure applicators are for closures selected from can lids, crimped crown closures, screw cap style closures and combinations thereof;
• and
• f. feeding the filled and closed stream multiple of container types by a third starwheel.
