BTRS Return Conveyor for Straight-Line & Gang Rip Saws
Doucet BTRS is a rip-saw-specific return conveyor family offered as BTRS-68, BTRS-70 and BTRS-71. Adjustable receiving and return conveyor speeds are 40–120 ft/min, the perpendicular belt-transfer speed is fixed at 180 ft/min, the receiving conveyor is 5 feet, and each model retains its own return geometry.

Production problem
Boards exiting a straight-line or gang rip saw need a controlled route back to the operator without repeated manual carrying around the saw.
Machine mechanism
End-of-board detection triggers receiving-roller retraction; perpendicular transfer belts move the board to powered return rollers.
Model geometry
BTRS-68, -70 and -71 have different receiving/return widths, return lengths and transfer widths; BTRS-70 uniquely uses canted return rollers.

Start with the production problem
Return ripped stock to the operator while preserving the saw's feed path and board orientation.
BTRS is designed around rip-saw outfeed geometry, with receiving, perpendicular transfer and return stages matched to the selected layout.
Detection
Detect end of board
End-of-board detection triggers receiving-roller retraction.
Transfer
Transfer perpendicular
Belts move the board perpendicular to the saw feed toward the return rollers.
Return
Return to operator
Motorized return rollers bring material back on the selected BTRS geometry.
Application fit
Best fit: straight-line rip saw and gang rip saw cells that need a dedicated operator-side return.
The product page explicitly names both host-machine types and says the three BTRS models cover different widths and lengths to suit ripping applications.

Machine architecture / work cycle
Receive → detect → retract → lift/transfer perpendicular → powered return.
The perpendicular belt transfer moves vertically using pneumatic-cylinder actuation.
Receive
1 — Receive
Board exits the rip saw onto individually driven PVC receiving rollers.
Retract
2 — Detect / retract
End-of-board detection initiates receiving-roller retraction.
Transfer
3 — Transfer
Perpendicular belts move vertically via pneumatic-cylinder actuation and carry the board to the return rollers.
Return
4 — Return
Motorized return rollers carry the board back to the operator.
Model comparison
BTRS-68 / 70 / 71 dimensions.
Each dimensional value remains tied to the named model.
BTRS geometry
All three models support a one-operator workflow, but the conveyor geometry changes materially.
BTRS-68 returns material beside the table two inches below table height; BTRS-70 returns onto the table at table height; BTRS-71 returns beside the table at table height.
BTRS-70 may require rip-saw table modification when indicated distance “A” exceeds 18 inches.

Configuration note: 40–120 ft/min applies to the receiving and return conveyors. 180 ft/min applies only to perpendicular belt transfer. BTRS-70 canted return rollers are specific to BTRS-70.
BTRS-68
Side return, two inches below rip-saw table height.
BTRS-68 returns material to the operator beside the saw table.
BTRS-68 geometry
29-inch receiving width, 24-inch return width, 11-foot return length and 78-inch transfer width.
29-inch receiving width, 24-inch return width, 11-foot return length and 78-inch transfer width are specific to BTRS-68.
BTRS-68 returns material beside the rip-saw table, two inches below table height.
BTRS-70
Return onto the rip-saw table at table height, with canted return rollers.
BTRS-70 uses canted return rollers and returns stock onto the rip-saw table at table height.

Ownership / service / changeover
Keep the selected BTRS geometry tied to the host rip-saw cell.
Keep pneumatic, drive and safeguarding service tied to the installed BTRS and host-saw procedures.
Configuration
Model records
Document whether the installation is BTRS-68, -70 or -71 and any length extensions.
Ownership
Roller / belt condition
Receiving rollers, transfer belts and return rollers are the core material-flow surfaces.
Changeover
Caster / quick-release package
Record mobility options because they affect setup and line access.
Safety
Qualified service
Pneumatic, electrical and powered-conveyor service follows installed-machine documentation.
Production-cell integration
The rip saw defines return height, receiving position and model choice.
BTRS-70 in particular can involve saw-table interface considerations, so layout review belongs before final configuration.
Rip-saw outfeed
Board exits onto 5-foot receiving conveyor.
End-of-board detect
Receiving rollers retract.
Perpendicular transfer
Pneumatic vertical belt system moves the board sideways.
Model-specific return
BTRS-68/-70/-71 return geometry determines side/table relationship.
Operator receives
Motorized rollers return stock for the next handling step.
Business-case framework
Measure rip-saw outfeed handling and operator travel instead of assigning generic savings.
Build the business case from measured handling time, operator travel, saw waiting and the selected return geometry.
