Abstract

A method for shifting goods in which goods arranged in a predetermined manner within a container having an opening portion are taken out of the container in such a manner as to correspond to the arrangement of the storing state of the goods. The method comprising the steps of superposing a goods take-out tool including partitions which are formed in such a manner as to correspond to the arrangement of the storing state of the goods on the opening portion of the container, and inverting the superposed container and goods take-out tool. The goods in the container can be taken into the goods take-out tool without changing the arrangement of the storing state of the goods.

Claims

1. A method for shifting goods arranged in a predetermined manner within a container having an opening portion in which the goods are taken out of the container in such a manner as to correspond to the arrangement of a storing state of the goods which are standing in the container, the method comprising the steps of:

superposing a goods take-out tool over the container in which the goods are standing, the goods take-out tool including partitions which correspond to the arrangement of the storing state of the goods;

inserting a foremost end portion of the goods take-out tool into the opening portion of the container, the foremost end portion including end portions of the partitions;

inverting the container and superposed goods take-out tool;

removing the goods from the container into the goods take-out tool without changing the arrangement of the storing state of the goods, said goods being guided by the end portions of the partitions inserted into the container as said goods move into the goods take-out tool;

providing a shutter in the goods take-out tool, said shutter initially blocking movement of the goods from the goods take-out tool when the container and goods take-out tool are inverted, and

sliding the shutter out of the goods take-out tool to permit at least a portion of the goods to be removed therefrom.

2. The method as recited in claim 1, further comprising the step of temporarily storing the goods within the goods take-out tool after the goods are removed from the container.

3. The method as recited in claim 1, wherein during the step of removing, the goods moving into the take-out tool are first only partially held within the take-out tool while remaining within the container and are thereafter released by the take-out tool to thereby be removed from both the container and the take-out tool.

4. The method as recited in claim 3, wherein the shutter is provided with a plurality of sections, and wherein the goods are standing in the container in a plurality of rows and columns, each of the sections of shutters generally having the same width as one row of goods, the method further comprising the steps of:

moving one of the sections of shutters in a first direction to sequentially discharge each of the goods in one of the rows of goods; and

sequentially moving each of the sections of shutters to thereby discharge each of the columns of goods.

5. The method as recited in claim 1, further comprising the steps of:

passing the goods from the goods take-out tool to a goods drop-out device; and

sequentially removing the goods from the goods drop-out device.

6. The method as recited in claim 5, wherein the goods are standing in the container in a plurality of rows and columns and wherein the goods continue to stand in a plurality of rows and columns when positioned in the goods take-out tool, the method further comprising the steps of:

providing a sectional shutter beneath the goods drop-out device, each section of the shutter generally having the same width as one row of goods;

moving each of the sections of shutters in a first direction to sequentially discharge each of the goods in one of the rows of goods during the step of sequentially removing the goods from the goods drop-out device; and

sequentially moving each of the sections of shutters to thereby discharge each of the columns of goods during the step of sequentially removing the goods from the goods drop-out device.

7. A method for taking out goods, by a desired number, from a container containing a plurality of goods therein, the container having a plurality of partitions dividing the goods into different rows and columns, said method comprising the steps of:

separating the goods within the container by a goods take-out tool, said goods take-out tool including partitions which correspond to the arrangement of the partitions between the goods in a storing state when the goods are standing in the container; and

removing such separated goods, by a desired number, by moving a shutter positioned beneath the goods separated by the goods take-out tool, the shutter being moved to sequentially release goods from the different rows and columns according to a goods take-out command.

8. The method as recited in claim 7, further comprising the steps of:

placing the goods take-out tool over a goods drop-out device, said goods drop-out device having a plurality of goods storing positions corresponding to the partitions of the goods take-out tool;

removing the goods from the goods take-out tool and placing the goods in the goods drop-out device;

providing the shutter with a plurality of sections, each section generally having the same width as one row of goods whereby movement of one section results in sequential removal of goods from a particular row of goods; and

sequentially moving each of the sections of shutters to thereby remove all of the columns of goods.

9. The method as recited in claim 8, wherein the plurality of sections of the shutters are sequentially moved by sliding in a generally horizontal plane.

10. The method as recited in claim 8, wherein the plurality of sections of shutters are sequentially pivoted during the step of sequentially moving and further comprising the steps of:

providing a plane shutter for covering at least a portion of the bottom of the goods drop-out device, said plane shutter having the plurality of sections of pivotable shutters positioned along an edge thereof; and

moving the plane shutter after the plurality of sections of shutters have pivoted discharging a row of goods to thereafter position said plurality of sections of shutters beneath a different column of goods to be discharged.

11. The method as recited in claim 7, further comprising the steps of:

providing a goods drop-out device with the shutter which comprises a plane shutter and a caterpillar shutter, said plane shutter being movable in a first direction for release of goods in a column and said caterpillar shutter being movable in a second direction for release of goods in a row; and

moving the plane shutter and caterpillar shutter to thereby remove the goods from the goods drop-out device.

12. A method for taking goods from goods storing positions arranged in a matrix shape by shutters which open and close an opening portion of the goods storing portions, a desired number of goods being taken out by moving the shutters, said method comprising the steps of:

determining a total number of positions in one row of the matrix shape and a total number of positions in one column of the matrix shape;

determining the total number of positions within the matrix shape, said total number of positions corresponding to a total number of goods to be taken out;

converting each of the positions of the matrix shape to an n-ary number, the n-ary number having a first and second digit, the first digit representing an X location of the position in the matrix shape and the second digit representing a Y location of the position in the matrix shape;

selecting a desired amount of goods to be taken out;

converting the number of desired goods to an n-ary number;

moving one of the shutters with reference to the first digit of the converted n-ary number;

moving another one of the shutters with reference to the second digit of the converted n-ary number; and

discharging the selected amount of goods upon the moving of the shutters.

13. The method as set forth in claim 12, wherein the desired amount of goods is less than the total number of goods in the matrix shape, further comprising the steps of:

selecting a second desired amount of goods to be taken out;

converting the second desired amount of goods to a second n-ary number, the second n-ary number being based on the previously converted n-ary number of the first desired goods;

moving the one shutter with reference to the first digit of the second converted n-ary number;

moving the another shutter with reference to the second digit of the second converted n-ary number; and

discharging the second selected amount of goods upon the moving of the shutters.
