TYPICAL SEQUENCE OF OPERATION
1. Old Coil End is stopped in the shear area of the QM.
2. Exit Side Guide closes, centering the Old Coil End.
3. Exit Weld Clamp Closes.
4. New Coil End is stopped in the shear area of the QM.
5. Entry Side Guide closes, centering the New Coil End.
6. Entry Weld Clamp closes.
7. Camber Compensation of the New Coil End.
8. The Double Cut Shear cuts both Coil Ends simultaneously.
9. Entry Weld Clamp positively positions (overlaps) New
Coil End with the Old Coil End. At the same time, the Exit
Clamp tilts up and down, assuring that the overlap occurs.
10. Weld and Planish Wheels pass across the overlapped
joint, welding the ends together.
11. QM resets and the process line can restart.
MAIN OPTIONS
A. Full Automation - The machine operates automatically,
and all weld parameters are determined automatically
from strip data obtained from the PLC.
B. Hole Punch - Used to identify, track, and locate the
weld as it passes through the process line.
C. Strip Edge Notcher - Used to notch the weld start and
stop areas off the joined coil ends. It is also used to
remove the "wings" when welding a new wide coil end to
a narrow old coil end. These are also used for Side Trimmer
insertion and removal.
D. Preload Station - This allows the QM to operate as fast
as possible. The new coil end is placed into the special
entry weld clamp while the old coil is still running. It
includes thread tables, strip retractors, and side guides
for each passline.
Guild International has a complete line of Coil End Welders
for almost any application.
