Corner Transfer/Overpass Conveyor
The REL Corner Transfer/Overpass Conveyor is built to either feed the first board flipper or
by-pass the first flipper and feed the second board flipper. The overpass portion of this
conveyor consists of a stationary lineshaft driven roller bed that moves the board over the
top of the corner transfer portion of this conveyor to feed the second board flipper. The
corner transfer portion of this conveyor consists of a stationary lineshaft driven roller bed,
and pop-up belt transfer with an integral vacuum system. The function of the corner transfer
portion is to take board moving down the line and change its direction, exiting at a right angle
to the infeed flow and depositing the board on the first board flipper. As the board enters
the infeed end on the roller bed, sensors indicate position up against the stop fence. The belt
bed then raises by way of a rotary servo motor, lifting the board off the rollers and
transferring it off the conveyor. The vacuum assist on the belt bed helps in maintaining good
contact with the conveyor belts to prevent slipping as the board accelerates.
Board Flipper #1 & #2 Conveyors
The REL Board Flipper Conveyors are built to flip the board from a face up orientation to a
face down orientation. Flipper #1 consists of an infeed driven belt bed that transfers the
board to the flipper arms that perform the flipping process, and an out-feed driven belt bed
that transfers the board to the corner transfer conveyor. As the board enters the infeed end
on the belt bed, sensors detect the position of the board and stop the infeed belts when the
leading edge of the board reaches the pivot point of the flipper arm mechanism. The lifting
arm side of the flipper tilts the board to approximately 90 degrees allowing the board to
transfer to the lowering arm side of the flipper. The lowering arm then pivots down to the
horizontal position and leaves the board on the outfeed belt bed which moves the panel on
to the corner transfer conveyor. Flipper #2 is similar to flipper #1 with the exception that it
does not incorporate an infeed belt bed. The lifting flipper arms nest with the rollers on the
overpass conveyor.
Although the primary purpose of the this line is to paint the back side of the board, a
secondary function is to apply a third coat of paint to the front side of the board. In this mode
all board will travel through Flipper #1, but will not be flipped. The board will simply pass
through on the belt conveyors.
Corner Transfer Conveyor
The REL Corner Transfer Conveyor consists of a stationary line shaft driven roller bed, and
pop-up belt transfer with an integral vacuum system. The function of the corner transfer
conveyor is to take board moving down the line and change its direction, exiting at a right
angle to the infeed flow. As the board enters the infeed end on the roller bed, sensors indicate
position up against the stop fence. The belt bed then raises by way of a rotary servo motor,
lifting the board off the rollers and transferring it off the conveyor. The vacuum assist on the
belt bed helps in maintaining good contact with the conveyor belts to prevent slipping as the
board accelerates.
The two high speed transfer conveyors on the outfeed side of the flippers work as the traffic
control conveyors for metering the two product streams back into one flow going into the
board accumulator.
