pack, tie up, bale
梱 centers on securing items together for transport or storage: packing, tying up, or making a bale.
梱 combines 木 (tree, wood) with 困, which likely contributes the sound コン and may suggest the idea of enclosing or binding. The character likely originally referred to wooden materials used for tying or packing.
A tree 木 is surrounded and tied up 困, like wooden planks being bound together into a tight pack or bale.
For コン, imagine a con artist tying up wooden crates to pack them for a scam: con -> コン, and the wood is bound tight.
