Tool storage system, production plant and method for manipulating with such a tool storage system

The invention relates to a tool storage system (32) as well as to a production facility (1) for free-form bending of workpieces (2) made from a metal sheet, by means of a bending press (3), comprising a tool storage unit (30), a tool manipulation unit (31), and a provisioning unit (55) having provisioning rails (56, 57). The tool storage unit (30) has an upper and lower storage rail (34, 35), which are disposed spaced apart from one another at a vertical distance, as well as locally fixed in place relative to one another. The tool manipulation unit (31) has tool manipulation devices (36, 37), wherein each of the same comprises a working rail (38, 42), an auxiliary rail (39, 43), a drawing-in device (40, 44), as well as a pushing-out device (41, 45). Each of the tool manipulation devices (36, 37) can be displaced laterally next to the storage rails (34, 35), along a longitudinal guide arrangement (46, 47). Furthermore, the invention also comprises a method for manipulation of at least one bending tool (4) in such a tool storage system (32).
