2. The gantry moves to its home position, which is in the far reverse position, where the gantry is in the
picking position.
Homing is initiated by placing the Mode selector switch to Auto and then pressing the Home Machine
button on the touch screen Main screen.
B - Find Stack
Once the machine is Homed, or when a new stack is placed in the feeder, stack height should always be
checked.
Pressing the Find Stack button on the Main screen of the touch screen will cause the carriage beam to
begin lowering in search of the top of the stack.
When the plunger sensor detects the top of the stack, the stack height is recorded, and the carriage
beam returns to Home position.
Feeder Sequence of Operation
1.
Pick Board Command
a.
Table communicates “Pick Board” to the i-BF, or
b.
Set the mode selector switch to Auto. Then from the touch screen press menu item "Pick Board"
once and then within 2 seconds a second time to acknowledge the action.
2.
The Carriage Beam moves quickly down to a position just above the media stack.
3.
The Carriage Beam moves slowly down until the plunger sensor detects the stack.
4.
The Carriage Beam continues to move downward to the “Pick Sheet Additional Travel” distance.
a.
The additional travel distance is useful when running warped materials as it allows all of the
suction cups to contact the board to be picked by lowering the beam until all cups touch the
board.
5.
The Carriage Beam dwells for the “Delay to Build Vacuum Time” which allows vacuum to build at the
suction cups contacting the board to be lifted.
6.
Once the “Delay to Build Vacuum Time” elapses, the carriage moves upward to the “Pick Pause”
distance, at the set Raise to Pick Pause velocity.
a.
Raising slowly to the Pick Pause position helps separate the media from the stack.
7.
Once at the Pick Pause position, the i-BF checks to see that the vacuum level is above the “Low
Vacuum Set Point”.
If no, the i-BF will fault with “Fail to Pick Board” fault. Then check the cause why there is low
vacuum. If yes, then the carriage moves upward with the board.
8.
Shaker Mode Option.
The Shaker Mode option is enabled on the touch screen. When enabled the gantry will make several
up/down oscillations as set in the shaker mode parameters on the touch screen.
The shaker mode is helpful during picking in separating some media types.
9.
The Carriage Beam moves upward with the board to the upper Home position.
