Method for automatically exchanging a sleeve of a printing tool

Abstract

A method is provided for automatically exchanging a sleeve (18a) of a printing tool (14, 16, 18, 22, 24) mounted in a printing machine (12), in particular a flexographic printing machine, by means of a printing tool handling unit (28) comprising a coupling interface (36). In one step of the method the printing tool handling unit (28) is temporarily coupled to a coupling interface (46) located at the end of a shaft (54, 56, 58, 60) of the printing tool (14, 16, 18, 22, 24) with its coupling interface (36). In a further step, the printing tool handling unit (28) transports the printing tool (14, 16, 18, 22, 24) to a separation unit (78) comprising at least one clamping device (80, 82, 84) and places the printing tool (14, 16, 18, 22, 24) in the clamping device (80) of the separation unit (78). The printing tool (14, 16, 18, 22, 24), in particular a sleeve (18a) of the printing tool (14, 16, 18, 22, 24), is clamped by the clamping device (80), and the printing tool handling unit (28) separates the shaft (54, 56, 58, 60) from the sleeve (18a) by pulling the shaft (54, 56, 58, 60) out of the sleeve (18a) while the sleeve (18a) is clamped in the clamping device (80).
