1. A bending tool storage device (1) for storing bending tools (2), the bending tool storage device (1) comprising:
a rack (3) on which a plurality of storage locations (4) for the bending tools (2) are arranged, each of the plurality of storage locations (4) for storing therein at least a respective one of the bending tools (2),
at least one supply path (10) in the form of a supply path tool guide (11), the at least one supply path (10) for supplying the bending tools (2) to a bending press (27) and/or for retrieving the bending tools (2) from the bending press (27),
at least one first transfer device (5) for transferring the bending tools (2) between the plurality of storage locations (4) and a transfer point (6),
wherein the bending tool storage device (1) comprises, between the transfer point (6) and the at least one supply path (10), a rotating installation (7) for orienting the bending tools (2),
wherein the rotating installation (7) comprises at least one tool guide (9) rotatable about a rotation axis (8), said at least one tool guide (9) being in aligned orientation with the at least one supply path (10) in a first rotational position and pointing towards the transfer point (6) in a second rotational position,
wherein the plurality of storage locations (4) are arranged in at least two vertically spaced planes,
wherein each storage location (4) of the plurality of storage locations (4) has a respective longitudinal axis,
wherein for a first group (22) of storage locations of the plurality of storage locations, the longitudinal axes of two horizontally adjacent storage locations (4) of the first group (22) of storage locations extend parallel to one another,
wherein the at least one first transfer device (5) further comprises a tool holder (15) for holding a given bending tool (2) of the bending tools (2), the tool holder (15) being displaceable both horizontally and vertically,
wherein the plurality of storage locations (4) and the transfer point (6) can be approached by the at least one first transfer device (5),
wherein the storage device (1) further comprises at least one second transfer device (20) that is configured to move the given bending tool (2) of the bending tools (2) along the supply path tool guide (11), and
wherein the rotating installation (7) is supported by the rack (3) such that the rotating installation (7) is arranged in a shelf compartment of the rack (3).
