RACK: As in a curve, to bend the frame racks down in order
that the discharge elevation is lower than the infeed elevation.
RECEIVING END: The end of a conveyor from which the products
move toward you.
RETURN IDLER: A roller that supports the return run of the
belt.
REVERSIBLE: A conveyor that is designed to move product in
either direction.
ROLLER: A round part free to revolve about its outer surface.
The face may be straight, tapered or crowned. Rollers may also serve
as the rolling support for the load being conveyed.
ROLLER BED: A series of rollers used to support a conveying
medium.
ROLLER CENTERS: The distance measured along the carrying run
of a conveyor from the center of one roller to the center of the
next roller.
ROLLER CONVEYOR: A series of rollers supported in a frame
over which objects are advanced manually, by gravity or by power.
SET HIGH: Vertical spacing that allows the rollers to be
mounted above the frame rails.
SET LOW: Vertical spacing that allows the roller to be
mounted below the top of the frame rails.
SHAFT: A bar usually of steel, to support rotating parts or
to transmit power
SHEAVE: A grooved pulley wheel for carrying a v-belt.
SIDE CHANNELS: Members that support the rollers on the side
of the conveyor.
SIDE MOUNTED DRIVE: A drive assembly mounted to the side of
the conveyor, normally used when minimum elevations are required.
SIDE TABLES: Steel tables attached to either side of conveyor
bed to provide working surface close to conveyor.
SINGULATION MODE: Mode where packages are automatically
separated while traveling down the conveyor.
SKATEWHEEL CONVEYOR: A type of wheel conveyor making use of
series of skatewheels mounted on common shafts or axles, or mounted
on parallel spaced bars on individual axles.
SLAT CONVEYOR: A conveyor that uses steel or wooden slats
mounted on roller chain to transport the product.
SLAVE DRIVE: A conveyor drive powered from another conveyor
instead of having its own prime power source.
SLIDER BED: A stationary surface on which the carrying run of
a belt conveyor slides.
SLUG MODE: Allows all packages to be released simultaneously.
SNUB IDLER: Any rollers used to increase the arc of contact
between a belt and drive pulley.
SORTATION CONVEYOR: A conveyor that is able to sort different
packages or products to specific take-away lines. (SC, ProSort)
SPEED REDUCER: A power transmission mechanism designed to
provide a speed for the driven equipment less than that of the prime
mover. They are generally totally enclosed to retain lubricant and
prevent the entry of foreign material.
SPOOL CONVEYOR: A conveyor where power to the rollers is
accomplished by o-rings driven by spools on a rotating shaft.
(138-SP, 190-SP, 25l4-SP)
SPUR: A conveyor section to switch unit loads to and from the
mainline.
SUPPORT: Arrangement of members used to maintain the
elevation or alignment of the conveyors. Supports can take the form
of hangers, floor supports, or brackets and can be either stationary
or portable.
SWITCH: (1) Any device for connecting two or more contiguous
package conveyor lines; (2) An electrical control device.
