A Method for Determining the Maximum Permissible Speed of a Pallet on a Gravity Roller Conveyor

Gravity roller conveyors are widely used in warehouse intralogistics for moving pallets. Pallets with loads of various weights are accelerated to the maximum permissible speed and hit a pallet separator rest. An original method is proposed for determining the maximum permissible speed of a pallet on a gravity roller conveyor, based on Cox’s impact theory and providing safe operation of the pallet separator rest. The method is developed in a generalized form and can be used for determining the maximum permissible speed of pallets on the conveyor taking into account design parameters of the separator rest. The article presents an example of calculations for most commonly used pallets measuring 800х1200 mm and 1000х1200 mm, and a separator rest represented as a square tube with a welded plate. The calculation results are in a good agreement with the data by foreign manufacturers where the pallet speed is 0.2…0.3 m/sec.
