A direct-drive roller conveyor is a transport system designed to provide continuous movement of loads of various weights and sizes over a specified distance. Its key feature is the presence of a gear motor that drives the entire structure..
The powered roller conveyor (roller table) is designed for transporting unit loads with a flat bottom, such as boxes, pallets, wooden blanks, trays with products, and similar items. It is used to move goods within a workshop or between workshops and warehouses. These conveyors are widely utilized across various industries and help reduce labor costs associated with storage and material handling operations.
A powered roller conveyor is equipment that allows loads to be moved either horizontally or at an incline to a certain height. Unlike belt conveyors, roller conveyors can transport significantly heavier loads—up to 1500 kg/m³—making them suitable for demanding industrial applications.
Visually, the powered roller conveyor features a frame structure with a specific number of rollers fixed to it. The conveyor rollers are cylindrical in shape and are mounted on stationary shafts, rotating with the help of ball bearings. The rollers are driven by a motor-reducer, which is connected to them via a chain or belt transmission system.
The spacing between rollers can vary depending on the application; however, it is recommended that the distance does not exceed 1/3 of the length of the transported item to ensure stable and smooth movement.
Thanks to its ability to transport loads not only horizontally but also at a slight upward angle (up to 7° for heavy loads and up to 12° for lighter ones), the powered roller conveyor enables the automation of cargo movement throughout a warehouse or production facility. It also allows for the design of routes with virtually any geometry, making it a versatile solution for streamlining internal logistics.
Driven Rollers
Driven rollers consist of a housing, spindle, bearing, and drive element. The roller shaft is connected to the power transmission component, which may be a sprocket or a pulley. Driven rollers receive torque through a shaft with a keyway input, for example, from a gear motor mounted directly to the sides of the conveyor. In this way, further power transmission from one roller to another within the conveyor is possible using a chain or belt.
A roller conveyor can be powered in various ways. When selecting a drive system, it is important to consider the following:
Grooved rollers provide power transmission using belts manufactured to a standard with two grooves spaced 30 mm apart for roller-to-roller power transmission, or a single groove for transmitting power from a shaft positioned perpendicular to the rollers. In the latter case, it is recommended to use special rings on the shaft to increase the belt's turning diameter, maintain its perpendicular position relative to the rollers, and ensure sufficient friction — all these elements significantly extend the lifespan of the belts.
In the case of stainless steel rollers, to prevent deformation of the tube in the grooves — especially in rollers with a diameter of no more than 50 mm — polyamide-headed rollers are used for power transmission with belts (suitable for use in the food industry).
Rollers with heads for power transmission using poly-V belts offer significantly higher efficiency compared to round belts. This type of transmission allows energy to be transferred from one motor roller to up to five rollers when using poly-V belts, making them particularly attractive for conveyor system applications.
Rollers with sprockets. Another method of power transmission is the use of a roller chain, which enables the movement of heavy loads. These rollers are available with single or double sprockets, providing power transmission using a standard roller chain.
