Method for assembling rack and rack
A rack includes a plurality of floors each of which stores a plurality of bins for containing items, and allows a transportation robot to run along a surface thereof; and a plurality of support columns supporting the floors. Each of the floors includes a plurality of floor modules making up part of each of the floors, and each of the floor modules is detachably supported by the support column. This method for assembling a rack includes steps of: assembling each of the floors from a lower floor to an upper floor by attaching the floor module to the support column; and detaching the at least one floor module from the support column on each of the floors to secure a route for an operator to go down to the floor of the lower floor from the upper floor in the assembling step.
1 . A rack comprising:
a plurality of floors each of which stores a plurality of bins for containing items, and allows a transportation robot to run along a surface thereof; and
a plurality of support columns supporting the floors, each of the plurality of support columns having a main body, an insertion plug at one end of the main body and an accommodation plug at another end of the main body opposite to the insertion plug,
wherein each of the plurality of floors includes a plurality of floor modules making up part of each of the floors, and each of the floor modules is detachably supported by the accommodation plug with a floor reception part;
wherein at least one of the floor modules is detachable from the support columns of each floor to secure a route for an operator to go down to a lower floor from an upper floor of the plurality of floors.
2 . The rack according to claim 1 , wherein the floor module can be detached upward from the support column.
3 . The rack according to claim 1 , wherein each of the support columns extends between at least mutually neighboring ones of the floors, and each support column can be coupled to another of the support columns in a vertical direction.
4 . The rack according to claim 1 , wherein one of the support columns supports corner portions of the plurality of floor modules.
5 . The rack according to claim 1 , wherein at least one floor module is attachable to the support column on each floor to close the route after the operator goes down to the lower floor from the upper floor.
6 . The rack according to claim 1 , wherein the surface of each of the plurality of the floors is defined with movement routes for the transportation robots to run.
7 . The rack according to claim 1 , comprising a picking station at an edge of one of the floors,
wherein, the picking station is configured to pick the item from the plurality of bins transported by the transportation robot.
8 . The rack according to claim 7 , wherein the picking station is defined with picking positions at which the transportation robots transporting the bins are simultaneously aligned to enable the operator to pick work of the item from the bin.
9 . The rack according to claim 1 , wherein each of the plurality of floors is defined with a plurality of charging spots adapted to charge a battery of the transportation robot.
10 . The rack according to claim 1 , wherein each of the plurality of floors defines a plurality of sections.
11 . The rack according to claim 10 , wherein each of the plurality of sections is configured to create an outline adapted to receive the transportation robot and the bin.
12 . The rack according to claim 10 , wherein each of the plurality of floors defines a storage area including the section.
13 . A method for assembling the rack according to claim 9 , the method comprising steps of:
assembling each of the floors from a lowest floor to an uppermost floor by attaching the floor modules to the support columns; and
detaching the at least one floor module from the support columns on each of the floors to secure the route for the operator to go down to the lowest floor from the uppermost floor in the assembling step.
14 . The method for assembling the rack according to claim 13 , further comprising a step of closing the route by the detached floor module on the uppermost floor when the operator goes down from the uppermost floor to the lowest floor when assembly of all of the floors is completed.
15 . The method for assembling the rack according to claim 13 , wherein a position of the detached floor module is displaced in a horizontal direction from a position of the floor module detached on the respective floor above the uppermost floor.
16 . The method for assembling the rack according to claim 15 , wherein the displacement in the horizontal direction corresponds to a space of the one floor module.
17 . The method for assembling the rack according to claim 15 , wherein the route is formed in a step-like shape.
18 . The method for assembling the rack according to claim 13 , wherein the floor module can be detached upward from the support column.
19 . The method for assembling the rack according to claim 13 , wherein each of the support columns extends between at least mutually neighboring ones of the floors, and each support column can be coupled to another of the support columns in a vertical direction.
20 . The method for assembling the rack according to claim 13 , wherein each support column supports corner portions of the plurality of floor modules.
