Description

Method and System for Transporting Tote The present disclosure relates to a tote transfer method and a system thereof. In a logistics warehouse, items are stored in totes, and the items in the totes can be packed on the packing line by a manager or packing device. In the process of packing goods, the stacked totes are each transported to the packing line via a conveyor. At this time, depending on the condition of the tote or the condition of the conveyor, the position of the tote on the conveyor may not be accurately controlled, and a slip phenomenon may occur where the tote slides on the conveyor. For example, at conveyor branching points, merging points, spirals, sorters, etc., a tot may not stop precisely at the location where it is supposed to stop. As another example, if a tot needs to stop and then move again for merging or branching at conveyor branching points, merging points, spirals, or sorters, the tot may not move at the correct time and location. During the process of transporting totes, slippage can cause collisions between totes, which may result in the suspension of transport or damage to the items contained within the totes. Therefore, regarding the transfer method of totes, a new approach is required to prevent such slipping phenomena and provide an optimized warehouse management system.
