Sequence of Operation
1) The Can is brought to the input position on the Indexing Table.
2) A sensor detects the Can and:
a. Indexes the Can One station forward
b. The Lid sensor checks for the presence of a Lid. If a Lid is not present, One
is dropped and Fed to the seam station.
3) When the next Can is brought to the indexer Input station, it is further indexed one
position and the above condition regarding the Lid is checked.
4) Each time a new Can is brought to the indexing station, the indexer moves forward
one position at a time. Initially it is rapidly moved forward until a Can is brought
under the Seam station.
At the Seam Station
1) Once a Can is detected at the Seam Station (Can Sensor), it is lifted by means of
the pneumatic cylinder (Figure 1, P1) to the Chuck. At the top position a Limit
Switch (Figure 1, L2) is depressed indicating the Can is lifted. The Clutch is
engaged by means of the Pneumatic Cylinder (Figure 1, P3) and the Seam
operation begins. (refer to the section on Roller setting to understand the
operation).
Note: After engaging the clutch, the pneumatic cylinder retracts. It does not need to
hold the Clutch in the engaged position. The clutch disengages mechanically after
the Seam cycle is completed
2) After Seaming is completed, the clutch disengages. The Limit Switch (Figure 1, L3)
at the rear is pressed to denote completion of the Seam Cycle.
3) The Can is brought down and as soon as the Lifter Limit Switch (L2) is released,
the Ejector (Figure 1, P2) is brought Down to ensure the Can is released from the
Seaming Chuck.
4) A previously separated and dropped Lid is Fed to the Seam position by the Lid
Feed rotary pneumatic cylinder (Figure 1, P5)
5) Provided there is a Can at the Input Station of the Indexing wheel, the Seamed Can
is indexed one station forward.
6) If the Can gets Jammed to the Seaming chuck and the Ejector is unable to press
the limit switch (Figure 1, L4), an Alarm is given and the machine is turned OFF.
The Indexer will not move forward in this condition.
