ROBOTIC PICK UP AND DELIVERY SYSTEM

摘要

A pick up and delivery system for use with mobile robots (12) which have a body with a horizontal upper surface and at least one vertical side. The robot has at least one shelf (24) each of which contains a stop bar (26) containing a retaining device (30). The system further uses multiple stations (14), each of which contains at least one pallet retaining surface (18) to contain at least two pallets (20). The pallet retaining surfaces are provided with a holding device (28) at the pick up area and a holding device (29) at the delivery area. Pallets are used to retain the items being transferred with each of the pallets having a securing device (46, 48) that interacts with the holding device and retaining device. The strength of the holding device at the pick up area is less than the holding device at the delivery area, with the robot's retaining device having a strength between the strength of the holding devices. The mobile robot picks up a pallet from a first station, and delivers the pallet to a second station.
