Abstract

Claims (34)

1. A method of distributing a plurality of articles made by serial production into a storage unit, comprising:

distributing a first article of the plurality of articles onto an article conveyor on a transport platform of an article distributing apparatus, the article conveyor being positioned in a start position above a storage area within the storage unit, the transport platform being in a first orientation;

driving the transport platform in a horizontal transport direction;

actuating the article conveyor to transport the first article in a first direction and off the transport platform so that the first article falls onto a floor of the storage area or onto at least one previously stacked article;

driving the transport platform back to the start position to receive a second article to be distributed into the storage area;

distributing the second article onto the article conveyor;

rotating the transport platform relative to the horizontal transport direction, so that the transport platform is in a second orientation, wherein the second orientation is coplanar with the first orientation in the horizontal transport direction; and

actuating the article conveyor to transport the second article in a second direction and off the transport platform, so that the second article falls onto the floor of the storage area or onto at least one previously stacked article, wherein the second direction is perpendicular to the horizontal transport direction.

2. The method of claim 1 , wherein each article of the plurality of articles is a bag of ice received from an ice making and bagging machine and the storage area comprises a temperature controlled storage unit.

3. The method of claim 2 , further comprising positioning each bag received on the transport platform in a horizontal orientation with a first face of the bag upwards prior to driving the transport platform in the horizontal transport direction.

4. The method of claim 3 , wherein the step of positioning each bag comprises driving the article conveyor in a predetermined direction as the bag is received onto the transport platform so as to rotate the bag into the horizontal orientation.

5. The method of claim 3 , wherein the step of transporting the bag off the transport platform comprises partially rotating the bag so that it rotates into a reverse orientation with a second face upwards as it falls from the transport platform.

6. The method of claim 1 , further comprising selecting a storage position for each of the first and second articles in the storage area from a plurality of storage positions in at least one row extending along the storage area beneath the article conveyor.

7. The method of claim 6 further comprising:

monitoring the fill level of the plurality of storage positions;

selecting a storage position for a third article from the plurality of storage positions, if the storage area is not full after distributing the second article into the storage area;

distributing the third article to the selected storage position for the third article in the storage area which is not full; and

continuing to distribute successive articles into successively selected storage positions from the plurality of storage positions in the storage area until all storage positions are full.

8. The method of claim 6 , wherein the storage area comprises at least two side-by-side rows of storage positions and the step of selecting a storage position comprises selecting at least one of the storage positions for the first, second, and third articles in a first or second row of the side-by-side rows.

9. The method of claim 8 , wherein, when the transport platform is in the first orientation, at least one end of the transport platform is located above the first row and wherein, when the transport platform is in the second orientation, at least one end of the transport platform is located above the second row.

10. The method of claim 9 , wherein the transport platform is positioned in the first or second orientation above the row in which the selected storage position is located prior to conveying at least one of the first, second, and third articles off the transport platform.

11. The method of claim 6 , further comprising monitoring the fill level of articles at each storage position in the storage area as the transport platform is driven back and forth in the horizontal transport direction over the storage positions and storing the current fill levels, wherein the step of selecting a storage position comprises analyzing the current stored fill levels and selecting a storage position which is not filled to capacity.

12. The method of claim 11 , wherein the selection of a storage position is based on a predetermined article distributing sequence for the plurality of storage positions and the current fill levels at each storage position.

13. The method of claim 6 , wherein the storage position for the first article is different from the storage position for the second article.

14. The method of claim 1 , wherein the first direction is aligned with the horizontal transport direction.

15. The method of claim 1 , wherein the second direction is perpendicular to the first direction.

16. A method of distributing a plurality of articles made by serial production into a storage unit, comprising:

distributing a first article of the plurality of articles onto an article conveyor on a transport platform of an article distributing apparatus positioned in a start position above a storage area within the storage unit, wherein the storage area comprises at least two side-by-side rows of a plurality of adjacent storage positions;

selecting a storage position from the plurality of adjacent storage positions in a first or second row of the at least two side-by-side rows;

driving the transport platform in a horizontal transport direction to a location above the selected storage position;

moving the transport platform between at least two different article distributing positions relative to the horizontal transport direction including a first article distributing position in which at least one end of the transport platform is located above the first row and a second article distributing position in which at least one end of the transport platform is located above the second row, wherein the transport platform is positioned in the first or second article distributing position above the row in which the selected storage position is located prior to conveying the article off the transport platform, wherein the step of moving comprises rotating the transport platform between at least two different article distributing orientations, and wherein the first article distributing position comprises an orientation aligned with the horizontal transport direction and the second article distributing position comprises an orientation which is transverse to the horizontal transport direction;

actuating the article conveyor to transport the article off the platform, whereby the article falls onto a floor of the storage area at the selected storage position or onto at least one previously stacked article at the selected storage position;

driving the transport platform back to the start position to receive a subsequent article to be distributed into the storage area; and

repeating the foregoing steps to distribute the plurality of articles one by one to selected storage positions in the storage area.
