Norpak Handling Ltd.’s selection of material-handling solutions includes a line of incline belt conveyors. These products are ideal for efficient conveying, which is why they are a crucial part of many plants and warehouses. Both incline and steep incline conveyors are proficient in moving unit loads on inclined planes.
Several factors should be taken into consideration when designing an incline belt conveyor, as Norpak discusses in a recent blog post.
Length and height of products
First, the designer should consider spatial constraints if any exist. Traditional incline conveyors may need ample space and length to achieve the perfect angle at which items can be transported without slippage, depending on angle and functionality. The next crucial factor is the angle of the incline: most incline units can function effectively only up to a specific angle, typically 25-to-30 degrees, after which slippage is more likely. Incline angle also determines the capacity of the power feeder.
The most fundamental factor to consider is the product dimensions, including length, height, and the load weight and its centre of gravity. Norpak points out that the latter two are vital to determine if the load is vulnerable to rolling or toppling. Slipping and toppling are preventable in most cases by selecting a conveyor belt that is most appropriate for an inclined plane: users should pick belts that can grip items firmly, counteracting other forces.
Other factors that may contribute to product toppling include belt speed, vibration, humidity, and temperature. The user must determine the maximum possible angle of inclination, denoted as δmax. To calculate this angle, place the item and belt onto a support structure (length denoted as LT), and tilt the structure slowly until the item begins to slide. The gradient at which this happens is represented as HT. In other words: δmax ≤ arc sin HT/LT. External forces like heat, temperature, and humidity will heavily influence the value of δmax too. As a result, the effective angle of incline will always be less than δmax.
Considering all of the above factors should result in the most suitable incline conveyor. Contact the experts at Norpak for guidance and assistance on designing and selecting an incline/decline conveyor for your system.
