Abstract

The present example of transferring and organizing articles from a shelf into a container, (or “controlled transfer and packing”) also allows a warehouse distribution system to be provided that receives items from a manufacturer or distributor, and boxes or packages the items to produce a shipment to another reseller, or customer, according to a received order in a way that may be efficient than current methods. In particular, the system makes use of a specialized floor plan and equipment that aids in processing the order according to the pricing methods described. The processing also provides an example of transferring and organizing articles from a shelf into a container that controls article tumble when loading the article into a container that tends to increase packing efficiency. Loading of items to be packed into magazines to aid transferring of articles from a shelf into a container is also described.

Claims

1. An autonomous apparatus for transferring and organizing articles from a shelf surface into a container in response to an order from a single customer, the apparatus comprising:

a bulk storage shelf located in a first area, the bulk storage shelf including a planar shelf surface for storing the articles in bulk;

a rack shelf located in a second area separate from the first area, the rack shelf including a tilted shelf surface, opposed first and second ends, and opposed first and second sides each having lateral rails mounted thereon between the first and second ends;

a clip trolley vehicle mounted to the rails for lateral movement thereon across the rack shelf between the first and second ends, the clip trolley vehicle carrying transfer channel clips loaded with transferred articles transferred from the bulk storage shelf, and the clip trolley vehicle for loading the transfer channel clips onto the tilted shelf surface of the rack shelf;

each transfer channel clip includes a flooring surface, parallel walls, an end wall, an open transferring edge opposed from the end wall, and a screw assembly operatively coupled to a push-up surface for pushing articles in the transfer channel clip toward the transferring edge;

a pick trolley vehicle mounted to the rails for lateral movement thereon across the rack shelf between the first and second ends, the pick trolley vehicle including a container and a coupler configured to engage with the screw assembly on one of the transfer channel clips to advance the push-up surface toward the transferring edge in response to activation of the coupler on the pick trolley vehicle, thereby pushing one of the articles in the one of transfer channel clips toward the container in the pick trolley vehicle; and

a first sensor on the pick trolley vehicle configured to detect receipt of the article in the container on the pick trolley vehicle;

wherein the pick trolley vehicle moves along the rails of the rack shelf in response to the first sensor detecting the receipt of the article in the container on the pick trolley vehicle.

2. The apparatus of claim 1, wherein:

the coupler on the pick trolley vehicle advances toward the one of the transfer channel clips to engage with the screw assembly on the one of the transfer channel clips and engages with the screw assembly to advance the push-up surface; and

the coupler on the pick trolley vehicle retracts from the one of the transfer channel clips to disengage with the screw assembly in response to the first sensor on the pick trolley vehicle detecting receipt of the article in the container on the pick trolley vehicle.

3. The apparatus of claim 1, further comprising a second sensor, located on the pick trolley vehicle, determines the number of articles remaining on the transfer channel clip on the rack shelf.

4. The apparatus of claim 1, further comprising:

a camera on the pick trolley vehicle which captures images of each article on the rack shelf as the pick trolley moves laterally across the rack shelf; and

a computer operatively coupled to the pick trolley vehicle compares the images of each article to a database of the articles and rack shelf locations for the articles.

5. The apparatus of claim 1, wherein:

a conductor bar is mounted to the rails and delivers power to the pick trolley vehicle;

a rack is mounted to the rails and engages with a pinion carried on the pick trolley vehicle to drive the pick trolley vehicle across the rails; and

the conductor bar includes spaced-apart conductors extending between the first and second ends of each of the rails to provide power to the pick trolley vehicle between the first and second ends.

6. The apparatus of claim 1, further comprising:

turning turrets disposed at the opposed first and seconds ends of the rack shelf;

the turning turrets convey the clip trolley vehicles and the pick trolley vehicles between the rails mounted on the first and second rails.

7. The apparatus of claim 1, wherein the container carried by the pick trolley vehicle defines a shipping container for the articles received in the container.

8. The apparatus of claim 1, further comprising:

a clip loading area located in a third area separate from the first and second areas;

each transfer channel clip moves between a loading condition, a storage condition, and a transfer condition;

in the loading condition of each transfer channel clip, the transfer channel clip is disposed in the clip loading area to be loaded with separated articles separated from the articles in bulk on the bulk storage area;

in the storage condition of each transfer channel clip, the transfer channel clip is disposed on the tilted shelf surface of the rack shelf available to be picked from by the pick trolley vehicle; and

in the transfer condition, the clip trolley vehicle carries the transfer channel clip from the clip loading area in the third area to the rack shelf in the second area.
