System of handling containers
System for handling containers and a method for supplying inventory items to a fulfilment station in a warehouse or in any other location where fulfilment of orders or delivery of orders, for example grocery orders, is taking place. The system includes at least one mobile inventory carrier for storing containers, a mini load system including a gripping mechanism for picking up or releasing a container from the mobile inventory carrier and autonomous mobile robotic units, wherein the mini load system, the mobile inventory carrier and the autonomous mobile robotic unit(s) are distinct units and operate independently from each other.
1 . A system for handling containers comprising:
at least one mobile inventory carrier for storing containers;
a mini load system including a gripping mechanism for picking up or releasing a container from the at least one mobile inventory carrier; and
at least one autonomous mobile robot unit;
wherein the mini load system, the at least one mobile inventory carrier and the at least one autonomous mobile robot are distinct units and operate independently from each other, the mini load system including:
a pedestal, the at least one mobile inventory carrier being attached on said pedestal; and
wherein the at least one autonomous mobile robot unit is configured to move together the mini load system and the at least one mobile inventory carrier within a workplace.
2 . The system according to claim 1 , wherein the at least one autonomous mobile robot unit is configured to transport the at least one mobile inventory carrier within a workplace.
3 . The system according to claim 1 , wherein the at least one mobile inventory carrier comprises:
one or more wheels.
4 . The system according to claim 1 , wherein the at least one mobile inventory carrier comprises:
a pedestal.
5 . The system according to claim 4 , wherein the pedestal comprises:
rails and one or more wheels coupled to the rails.
6 . The system according to claim 1 , wherein the autonomous mobile robot unit is wireless and comprises:
an integrated rechargeable battery.
7 . The system according to claim 6 wherein the battery of the at least one autonomous mobile robot unit is configured and arranged to provide power to the mini load system.
8 . The system according to claim 1 , wherein the at least one mobile inventory carrier is configured to be freely mounted in a workplace; and
wherein the at least one autonomous mobile robot unit is configured to lift and/or rotate the mobile inventory carrier.
9 . The system according to claim 8 , wherein the at least one mobile inventory carrier comprises:
one or more wheels.
10 . The system according to claim 9 , wherein the mini load system comprises:
a gantry system including a frame, a pair of gantry joints and a container handler.
11 . The system according to claim 10 , wherein the at least one mobile inventory carrier comprises
a pedestal.
12 . The system according to claim 11 , wherein the autonomous mobile robot unit is wireless and comprises:
an integrated rechargeable battery.
13 . The system according to claim 1 , wherein the mini load system comprises:
a gantry system including a frame, a pair of gantry joints and a container handler.
14 . The system according to claim 13 , wherein the frame is fixedly attached to a pedestal.
15 . The system according to claim 13 , wherein the gripping mechanism of the mini load system comprises:
at least one camera; and
at least one lighting means.
16 . The system according to claim 15 wherein the gripping mechanism is configured to identify angular and/or linear deviations of the mobile inventory carrier and thereby guide movements of the pair of the gantry joints and of the container handler.
17 . The system according to claim 15 wherein the at least one camera and the at least one lighting means are configured to generate a stream video that is configured to be processed by software means and to dictate the gripping mechanism to fetch a target container.
18 . A method for supplying inventory items to a fulfilment station, the method comprising:
a) transporting a first mobile inventory carrier with one or more filled donor containers by a first autonomous mobile robot unit from an inventory area of a fulfilment center to an exchange point;
b) loading the one or more containers of the first mobile inventory carrier by a mini load system to a second mobile inventory carrier, the second mobile inventory carrier being empty before loading;
c) repeating steps a) and b), until the second mobile inventory carrier is fully loaded with containers;
d) transporting the fully loaded second mobile inventory carrier by an autonomous mobile robot unit to a picking station of a fulfilment center;
e) transferring the second mobile inventory carrier onto a pedestal of a mini load system at the picking station;
f) selecting a first donor container from the second mobile inventory carrier and delivery of the first donor container to an operator location; and
g) selecting at least one item from the first donor container and placing of the item into an order container, wherein steps f) and g) are repeated until selected items from all the donor containers are placed them into the order container.
19 . The method according to claim 18 , comprising:
causing an autonomous mobile robot unit to arrive at the picking station of a fulfilment center,
placing the second mobile inventory carrier on a pedestal of a mini load system and lifting the second mobile inventory carrier via the autonomous mobile robot unit; and
returning, via the autonomous mobile robot unit, the second mobile inventory carrier to the inventory area of the fulfilment center, and placing it on a pedestal of a mini load system.
20 . The method according to claim 19 , comprising:
moving the autonomous mobile robotic unit to a charging station automatically to be recharged, when it is not involved in a process or when the battery is in a low level.
