Abstract

A storage system having at least first, second and third storage sections, each configured for storing containers in multiple storage cells arranged in multiple rows at various horizontal levels with respect to ground. Storage cells in each row are arranged in multiple parallel lines extending in a first horizontal direction. Container carriages are moved in the first horizontal direction along parallel paths corresponding to the lines of the storage cells. The container carriage having a frame and a board for carrying containers is configured to position the board at different horizontal levels with respect to the frame. The container carriage is enabled to load containers onto its board in a desired sequence by taking a selected container from a storage cell in one row of the storage section when the board is positioned at one horizontal level, and placing the selected container to a storage sell in another row when the board is positioned at another horizontal level.

Claims

1. A storage system comprising:

multiple storage sections, each configured for storing containers in multiple storage cells arranged in multiple rows at various horizontal levels with respect to ground, the storage cells in each row being arranged in multiple parallel lines extending in a first horizontal direction, the storing sections being arranged so as to provide at least first and second passages between the storage sections; and

a plurality of container carriages configured for moving in the first horizontal direction along respective parallel paths corresponding to the lines of the storage cells,

a container carriage of the plurality of container carriages having a frame and a board for carrying containers, the container carriage being configured to position the board at first, second and third horizontal levels with respect to the frame,

the container carriage being further configured to move between the first and second passages under the storage cells arranged in a first row of the storage sections when the board is positioned at the first horizontal level,

the container carriage being further configured for loading containers onto the board in a desired sequence by taking a selected container from a storage cell in a second row of the storage section when the board is positioned at the third horizontal level, and placing the selected container to a storage sell in the first row when the board is positioned at the second horizontal level, a transition of the board between the second and third horizontal levels being provided when the container carriage is positioned in a passage between the storage sections.

2. The system of claim 1, wherein the container carriage is configured for taking containers loaded onto the board from storage sections separated by another storage section.

3. The system of claim 1, wherein the container carriage is configured to move along one or more first rails extending in the first horizontal direction.

4. The system of claim 1, further comprising at least one lifting transportation device provided in each of the first and second passages and configured for moving along a pair of second rails extending along a passage in a second horizontal direction substantially perpendicular to the first horizontal direction so as to have access to the storage cells arranged in the storage sections from both sides from the passage, the lifting transportation device including a container access mechanism movable in a vertical direction with respect to the pair of second rails so as to take one or more containers stored in the storage sections and make the one or more containers available for the container carriage by placing the one or more containers to one or more storage cells in the second row of the storage sections.

5. The system of claim 4, wherein the lifting transportation devices and the container carriages are configured for moving in different horizontal planes with respect to the ground so as to avoid interferences between the lifting transportation devices and the container carriages.

6. The system of claim 5, wherein the pair of second rails is arranged at a horizontal level above the horizontal level corresponding to the second row of the storage sections.

7. A method of loading containers in a desired sequence onto boards of container carriages movable along parallel paths in a first horizontal direction in a storage system having first, second and third storage sections configured for storing containers in multiple storage cells arranged in multiple rows including first and second rows at various horizontal levels with respect to ground, the storage cells in the first and second rows being arranged in multiple parallel lines extending in the first horizontal direction and corresponding to the paths of the container carriages, the storage sections being arranged so as to provide passages between adjacent storage sections, the method comprising:

selecting first, second and third containers held in the first, second and third storage sections, respectively, for loading onto a board of a selected container carriage,

positioning the board of the selected container carriage at a lower horizontal position to enable the selected container carriage to move under a respective line of the storage cells in the first row of the second storage section,

positioning the board of the selected container carriage at an upper horizontal position to enable the selected container carriage to take first, second and third selected containers of the desired sequence of containers from the second row of the first, second and third storage sections, respectively,

positioning the board of the selected container carriage at an intermediate horizontal position higher than the lower position but lower than the upper position, to enable the selected container carriage to place at least one of the first, second and third selected containers into the first row of at least one of the first, second and third storage sections, a transition between the upper position and the intermediate position being performed in a passage between the storage sections, and

controlling the selected container carriage to place the first, second and third selected containers in the desired sequence on the board.

8. The method of claim 7, wherein the board of the selected container carriage is positioned at the intermediate horizontal position to place at least one of the first, second and third selected containers into the first row of the second storage section arranged between the first storage section and the third storage section.

9. The method of claim 7, wherein the container carriages are configured to move in parallel along first rails extending in the first horizontal direction.

10. The method of claim 7, wherein the first, second and third selected containers are placed into the second row of the first, second and third storage sections by lifting transportation devices, each lifting transportation device being moved along a pair of second rails extending along a passage between the storage sections in a second horizontal direction substantially perpendicular to the first horizontal direction so as to access the storage cells arranged in the storage sections from both sides from the passage, the lifting transportation device includes a container access mechanism movable in a vertical direction with respect to the pair of second rails so as to take the first and second selected containers stored in the storage sections and place the first and second selected containers to the second row of the storage sections.

11. The method of claim 10, wherein the lifting transportation devices and the container carriages are moved in different horizontal planes with respect to the ground so as to avoid interferences between the lifting transportation device and the container carriages.

12. The method of claim 10, wherein the pair of second rails is arranged at a horizontal level above the horizontal level corresponding to the second row of the storage sections.
