Lid Feed System
The lid feeder uses a pneumatic separator with a pneumatic feeder. Each time a Can is
sensed on the machine, a lid is dropped by the separator and then fed by the arm to
the Seam position under the seaming chuck. It is then picked up by the Can when it
moves upward to be seamed.
Sensors are provided at the Lid drop position and at the Seam Position. A Lid will be
dropped and fed to the Seam position whenever a Can is first sensed at the Indexer
input station. The
The blades used on the separator are made according to the Lid height and no
adjustments are required, unless there is a change in dimensions.
Note that the Lid Separator / Feeder are highly sensitive to dimensional variations. All
dimensions are to be maintained within 0.10mm of the original. Any deviation may
cause the Lid Feeder to Jam and malfunction.
A sensor is provided at the Lid Stack to ensure sufficient lids are always in the stack. In
the event that the number of lids goes below the minimum required, the machine will be
put OFF and an Alarm will be given on the Display.
The Lid Separator and Feed Pneumatic Cylinders are provided with speed control
valves. Adjust the speed so that both operations are carried out smoothly
without any jerks.
