Parcel sorting system, method and a container therefor
A parcel sorting system is disclosed having bags located within rigid containers to form nested containers. The bags are configured to enable the bag to conform to an inner surface area of the rigid container. The resultant nested container can provide more efficient packing of packages and parcels for transportation.
1. A parcel sorting system, comprising:
at least one collapsible flexible parcel holder and at least one rigid container, the at least one collapsible flexible parcel holder including deployable elements, the at least one collapsible flexible parcel holder being locatable in a rigid container, said deployable elements being arranged so as to ensure external surfaces of the at least one collapsible flexible parcel holder substantially conforms to internal surfaces of the rigid container in which it is located, so as to create a combined, nested container, the nested container being configured and adapted so as to receive parcels in such a manner that packing density of parcels within the nested container is maximized,
wherein the nested container includes a removable lid portion attached to the at least one collapsible flexible parcel holder, the removable lid portion having a fastening means which is configured to couple to a fastening means of the at least one collapsible flexible parcel holder and a structural means which increases the stiffness of the at least one collapsible flexible parcel holder wherein the removable lid portion seals the at least one collapsible flexible parcel holder such that the contents of the at least one collapsible flexible parcel holder may be retained within the at least one collapsible flexible parcel holder, and
wherein the sealed at least one collapsible flexible parcel holder may be removed from the rigid container after one or more parcels have been received within the at least one collapsible flexible parcel holder and the removable lid portion has been attached to the at least one collapsible flexible parcel holder.
2. A parcel sorting system according to claim 1 , in which each nested container comprises:
parcels and packages for onward transportation to a discrete geographical location.
3. A parcel sorting system according to claim 1 , wherein the rigid container includes a fixing means which can engage with the deployable elements of the at least one collapsible flexible parcel holder so as to engage confirmation of the outer surfaces of the at least one collapsible flexible parcel holder with the inner surfaces of the rigid container.
4. A parcel sorting system according to claim 1 , comprising:
a presentation portion arranged so as to present the at least one collapsible flexible parcel holders to rigid containers to create separable nested containers;
a filling portion arranged so as to feed parcels and packages in to said nested containers;
a sealing and securing portion arranged so as to substantially seal and secure said parcels and packages within the flexible parcel holder within the nested containers; and
a separating portion arranged so as to remove said sealed and secured flexible parcel holders from said containers.
5. A parcel sorting system according to claim 1 comprising:
a grid-based storage system arranged so as to store at least one of said rigid containers and nested containers in stacks within a framework, the framework having a series of tracks or rails mounted thereon forming a grid pattern above the stacks of containers, the containers occupying a footprint of one grid space of the tracks or rails, the tracks or rails having operable thereon at least one robotic load handling device arranged so as to lift and retain one container and transport said container to a predetermined output port of the storage system.
6. A nested container configured and adapted for use in combination with the parcel sorting system of claim 1 , the nested container comprising:
a rigid outer container;
an inner flexible container, the inner container comprising deployable fixing means so as to enable conformation of the outer surfaces of the inner flexible container with the inner surfaces of the outer rigid container, and
a removable lid portion for attaching to the inner collapsible flexible container, the removable lid including:
a fastening means which is configured to couple to a fastening means of the inner flexible container; and
a structural means which increases the stiffness of the inner flexible container,
wherein the removable lid seals the inner flexible container such that the contents of the inner flexible container may be retained within the inner flexible container.
