The BL Series belt drive stage is a low cost, durable and surprisingly quiet positioning stage that is well suited for both open and closed loop operation. The
stage is capable of very slow speeds (< 0.001inches per second) to speeds greater than 100 inches per second. Stages are offered with travel lengths up to 134
inches (3400 mm). The BL stage offers a pulley system designed for long service life and dependable operation. An optional external cable carrier is offered for
easy integration of cables and hoses. There are provisions for a linear encoder, which allow for dual loop operation in applications requiring precise positioning.
The carriage is supplied with tapped holes for easy mounting of your payload.
Stages can operate either horizontally or vertically and can be supplied in compound configurations for multi-axis applications.
The BL stage is offered with a bellows option (folded way covers) with a 12:1 extension to compression ratio. The bellows help to protect the belt and pulley
mechanisms from contamination in dirty environments.
Advantages:
· Quiet running, high speed
· Low cost
· Long life, low maintenance
· Linear encoder option
· Cable carrier option
· Bellows option
· Two bearing options
· Motor mounts directly to the stage, no motor mounts required
Applications:
· Pick and Place
· Parts Transfer
· Water Jet Cutting Machines
· Laser Cutting/Etching Machines
· Hi Speed Sewing Machines
The BL positioning stage incorporates the latest in linear motion technology:
· Motors: Depending on the system
requirements, stepper, DC brush and
brushless AC motors are available.
· Bearings: The table is supported by a
standard guide wheel type linear
bearing. A sealed recirculation ball
linear bearing option is available for
applications requiring precise motion of
heavier payloads.
· Encoders: The stage can be supplied
with an optional magnetic linear
encoder with quaderature output.
· Limit Switches: Optional end of travel
limit switches are available. The
switches can be used to shut down the
amplifier or to signal the controller that
an error has occurred.
· Cable Carriers: For management of
hoses and cables, a cable carrier option
is offered.
· Bellows: Neoprene / nylon bellows with
Mylar stiffeners are offered as an option
and provide protection in harsh
environments.
· Hard Stops: Hard stops are
incorporated into the ends of the stage to
prevent over travel damage in the event
of system runaway.
Required Electronics:
Depending on the type of motor selected, a stepper indexer/driver can be utilized for open loop step motor operation or a servo amplifier and programmable
motion controller can be utilized for closed loop servo motor operation.
Environmental Considerations:
The stage is offered with bellows, however care should be taken to protect the stage from contamination and moisture. The stage is designed for ambient
temperatures to 45 š C.
Mounting:
The stage should be mounted to a flat and rigid surface. Mounting slots are provided on the sides of the stage to allow for mounting to the customers platform.
The moving table assembly has threaded holes on the top surface for attaching the payload. The stage may be mounted in any orientation. When mounting the
stage with the table moving in a vertical direction, it should be noted that the stage will be required to generate additional force due to gravity and that the stage
will slide down to the bottom hard stop when power fails. A motor brake is available.
