Robotiq Screwdriving Solution - Instruction Manual
screw present
between the
singulator plates
2. Check for sensor error using the LED error codes(refer to
the ScrewFeeder Behavior section).
3. Validate if the singulator stops at the screw picking position
when the bottom sensor isobstructed. If so, screw head
height may be out of the device’s range.
Singulator does not
go to the screw
picking position or
to the rail position
The singulator moves but does
not complete the full movement
between the rail and the screw
picking position.
The LED indicator flashes red.
1. Check for blockages, and screwsthat might have fallen in
unwanted positions.
2. Check the head clearance adjustment. A loose head clear-
ance plate can cause the screw to tilt into the singulator
without fully engaging.
Screwscannot
board the rail
The screws are circulating
through the reclaiming wheel,
but are not traveling forward on
the rail.
1. Check the rail width adjustment; a rail gap that istoo nar-
row can prevent screwsfrom entering.Check for blockage; a
screw blocked on the rail can result in accumulation at the
reclaiming wheel unloading area, preventing screws from
moving forward.
2. Make sure the device islevel.
3. Make sure the screwsare within the required specifications.
Screwscannot
board the
reclaiming wheel
There are screwsin the chamber
but they are not going up the
reclaiming wheel.
1. Make sure the machine islevel.
2. Add screws in the Screw Feeder’schamber. Most of the
time, the difficulty for screws to go in the reclaiming wheel
results from an insufficient number of screws in the cham-
ber.
Screwscannot
move forward on
the rail or move
slowly
There are screwsgetting in the
rail and the reclaiming wheel is
operating normally, but the
screwsare not moving down the
rail, or are moving very slowly.
1. Check for blockage; a screw blocked on the rail can alter or
stop the vibration.
2. Make sure the machine islevel and resting on all four shoes
(rubber pads).
3. Review the Screw Feeder’sadjustments; an overtightened
rail, singulator plate or head clearance plate can prevent
the screwsfrom traveling appropriately.
4. Check that the chamber iscorrectly filled; too many screws
(over the max fill line) can prevent the rail from vibrating
properly.
5. Verify that the rail knob isclear from any interference, such
asa wall or a vertical surface; since this component vibrates
along with the rail, an external impediment can prevent the
screwsfrom moving forward.
Incorrect screws are
coming out of the
rail system
Incorrectly positioned screwsare
not sorted by the Screw Feeder
and are fed to the singulator.
1. Verify the Screw Feeder’sadjustments. A too low or too
high brush or head clearance plate can cause incorrectly
positioned screwsto travel to the singulator.
2. Verify that your screw iswithin the specified range.
