Troughed Bed Belt Conveyors
This slider bed belt conveyor includes a built-in side guard with its troughed frame design. Perhaps the most popular use of this conveyor is to convey “trash” or “scrap” to dumpsters or other containers for disposal (or recycling!) It is also commonly utilized containers for handling scrap cardboard, packing materials, and steel slugs. These units can easily be modified with a higher integral frame depth which will provide higher built-in guarding.
Slider Bed Belt Conveyors
The most popular of all powered conveyors remains the slider bed belt conveyor. This unit is very versatile, able to convey a wide variety of products. Many objects carried by the slider bed belt conveyor have uneven or difficult surfaces to convey for a live roller conveyor or may be very small or a various group of sizes — again presenting a challenge for a live roller conveyor to transport. Typical applications for the slider bed include packing, testing, inspecting, sorting, transportation and assembly.
Roller Bed Belt Conveyors
The roller bed is most commonly used for transporting heavier unit loads with low horsepower requirements. The decreased belt-to-transport-surface friction is much lower on roller bed belt conveyors than slider bed belt conveyors. (5% on roller beds compared to 30% on slider beds). Typical applications for the roller bed are packing, testing, inspecting, transportation and assembly. NOTE: Two rollers are required under the product at all times.
Inclined Floor-To-Floor Belt Conveyors
Floor-to-floor belt conveyors are used to transport a product up or down at 0 to 30 degrees. The maximum degree a product will convey is determined by the height, length and bottom conveying surface of the product. Single or double nose-overs are standard components. Chain driven feeders offer package separation or metering since it is slave driven from the inclined portion. Integral feeders are generally easier to track than chain driven feeders. Always add feeder when transferring product from gravity conveyors onto the inclined belt unit. Feeder length is normally equivalent to the longest product conveyed.
Belt Driven Live Roller Conveyors
Belt driven live roller conveyors are ideally suited for horizontal conveying of items where transfers, side loading, unloading, or temporary accumulation is required. Belt driven live rollers may be used when conveying heavier product loads. Also, a product slides across a roller much easier than a belt when loading or unloading from the side of a conveyor (assuming no transfer device is utilized) A number of 90 degree transfers may be mounted into belt driven live rollers to accommodate removal of products into operator work areas or onto perpendicular spur lines for accumulation, for example.
Belt Driven Live Roller Curves/Spurs
Belt driven live roller curves and spurs handle light and medium loads. These units are most commonly “slave-driven” from belt driven live roller conveyors to minimize number of drives required. The rollers on these units are driven by a tough B-section V-Belt. Curves are standard in both 45 degrees and 90 degree, but are also available in various other configurations – 30, 60 and 180 degrees are common. Curve/spur combination units provide merging/diverging capability for delivery to or from spur lines and are available in 45/45 degree and 60/30 degree. The 60/30 degree unit is desirable to use as a converging spur with its 30 degree spur.
Belt Driven Live Roller Minimum Pressure Accumulators
Belt driven live roller minimum pressure accumulators offer both transportation and accumulation features. Pneumatic or manual roller stops are used to stop the product flow while packages accumulate. The stops are used to stop the product flow while packages accumulate. The design of minimum pressure accumulators allows the drive belt tension to be variably adjusted so that the amount of back pressure is decreased. Minimum pressure accumulators work most effectively in temporary situations with long lines of accumulation, zero pressure accumulation conveyors should be utilized. Minimum pressure accumulators are ideal for use with belt driven live roller curves/spurs and when packages have to be stopped temporarily for assembly line operations.
Line Shaft Driven Live Roller Conveyors
The line shaft driven live roller conveyor is designed to conveyor, accumulate and transport relatively light products. Many sections and acessesories may be coupled to one drive which reduces the overall number of drives required and also, eliminates many electrical controls. A maximum drive capacity of 15 lbs. per roller is a quick method to immediately decide whether line shaft conveyor is a candidate for a particular application. In addition, line shaft should NOT be used when very slow speeds are required (less than 15 fpm. Roach is the only line shaft conveyor manufacturer to implent use of flexible jaw coupling and hytrel inserts which have drastically reduced installation and maintance time on this popular unit.
Line Shaft Driven Live Roller Curves/Spurs/Gates
Line shaft driven live roller curves and accessories are designed to convey, accumulate and transport relatively light products. These accessories may be coupled to one drive section thus reducing the overall number of drives required to operate. Like straight line shaft sections, drive capacity is 15 lbs. per roller. The standard durometer of line shaft bands i 85 durometer. In certain instances, drive bands are changed in order to provide additional driving force for line shaft conveyors.
