US 12,502,783 B2 · Method and a device for picking and placing items

Abstract

A method for picking and placing items includes the steps of: providing a picking conveyor transporting items to be picked; providing a placing conveyor to which the items are to be placed; and providing a plurality of robots configured to move the items from pick positions on the picking conveyor to place positions on the placing conveyor. For at least one of the plurality of robots there is defined an actual work area Aac that fulfils the condition Aac<Ath−(Aol+Aex), wherein Ath is a theoretical work area, Aol is an overlapping work area and Aex is an excessive work area of the respective robot. By limiting the actual work area Aac of the robots more than what is done conventionally, the total workload between the robots in pick and place systems may be balanced.
