Abstract

An automated apparatus suitable for transporting containers arranged in a row of stacks or partial stacks includes an overhead gantry system. The overhead gantry system has a moveable support for supporting at least one stack or partial stack of containers and moving them along the row. The gantry system also has an engagement device such as arms which are moveable transverse to the row independently of the support between a first position in which the engagement device can engage with a required container in the row, and a second position in which the engagement device and antcontainers engaged therewith are above the support to allow the containers to be placed either on the support or on another partial stack supported by the support. The support can travel along the row when the engagement device is in the second position.

Claims

1. Automated apparatus suitable for transporting containers arranged in a first row, the apparatus comprising an overhead gantry system,

the overhead gantry system comprising:

a moveable support for supporting at least one stack or partial stack of said containers, the support operable to move the at least one stack or partial stack of containers thereon along the first row;

engagement means moveable independently of said support in a direction transverse to the row between a first position in which the engagement means can engage with any selected container or containers from a selected stack or partial stack of containers in the first row, wherein the selected stack or partial stack comprises a plurality of containers, and a second position in which to engagement means, any container or containers engaged with the engagement means and any containers located on top of the container or containers engaged with the engagement means arc above said support; and

wherein the engagement means is moveable along the first row when the engagement means is in the second position, and can move the container or containers engaged with the engagement means vertically, thereby allowing a container or containers engaged with the engagement means to be placed either on the support or on partial stack supported by said support.

2. The apparatus of claim 1, wherein the second position is defined as any location between the first row and a second row extending substantially parallel to the first row, wherein the engagement means can travel along the first and second rows and wherein the apparatus is operable to move the engagement means transverse to the second row, between a third position where the engagement means can engage with any selected container or containers from a selected one of the stacks or partial stacks in the second row, and the second position.

3. The apparatus of claim 2, including conveying means to convey containers to the engagement means and receive containers from the engagement means and convey containers away from the engagement means, the conveying means extending into a gap along the length of said second row.

4. The apparatus of claim 1, including a guide that in use aligns a first partial stack located beneath the engagement means with a second partial stark engaged with the engagement means so as to allow the engagement means to release the second partial stack onto The first partial stack.

5. The apparatus of claim 1 suitable for transporting containers arranged on a floor in one or more rows of spaced apart stacks or partial stacks, wherein the engagement means includes at least one arm that is located in the space between stacks or partial stacks in the row or rows when the engagement means is in the first position.

6. The apparatus of claim 5, wherein the engagement means includes at least two anus spaced apart by either one or two columns in a row.

7. The apparatus of claim 5 suitable for transporting containers arranged on a floor in at least two adjacent rows of spaced apart stacks or partial stacks, wherein the at least one arm is dimensioned to be able to engage with containers across two or more rows.

8. The apparatus of claim 1, wherein the engagement means spans two or more stacks along a row and is engageable with at least one container in each of said two or more stacks.

9. The apparatus of claim 1, further including a conveyor extending along said row, wherein the engagement means is operable to retrieve and place stacks or partial stacks from or onto said conveyor respectively.

10. A container store including space to hold one or more rows of stacks of containers and the apparatus as claimed in claim 1, adjacent to said one or more rows, and wherein the container store includes in the line of at least one of said one or more rows of stacks a plurality of shelves for holding partial stacks, wherein the shelves are located, shaped and dimensioned so that the engagement means of said apparatus can engage with containers held on the shelves.

11. The container store of claim 10, wherein each shelf holds only a single container.

12. The container store of claim 10, further including one or more tails areas in which mixed containers of product are made by picking product from containers and placing picked product into a required container, wherein said apparatus is operable to retrieve mixed containers of product from the one or more tails areas and supply containers said one or more tails areas.

13. The apparatus of claim 1 wherein the moveable support is a moveable platform.

14. The apparatus of claim 13 wherein the moveable platform is adapted to support a plurality of stacks or partial stacks.

15. The apparatus of claim 13 wherein the moveable platform is adapted to support three stacks or partial stacks.
