  • the transport unit 10 is displaced along the rails 33 of the frame 30, preferably linearly, so that the pressure sleeve 2 can be conveyed to the intended working position 4 in the printing machine 6.
  • the operator 9 can grip, for example, the grip means 13 on a first and a second grip section 13.1, 13.2, each with one hand, in particular in one plane, and thereby adjust the transport unit 10 at least partially manually with both hands.
  • FIG. 4a shows an orientation of the transport unit 10 with the receiving means 11 at the working position 4, wherein the receiving means 11 is aligned with a sleeve receptacle 6.1.
  • the transport unit 10 can preferably be finely adjusted via the operating element 32 by the drive means 31 being controlled and causing a vertical movement of the receiving means 11.
  • a transfer 105 of the closure unit 20 from the security state I carried out in the delivery state III so that the pressure sleeve 2 the receiving means 11 in the direction of the working position 4 can be removed.
  • two pivot portions 23 of the second closure element 22 of the closure unit 20 are pivoted so that the receiving means 11 is released from the second closure element 22 and here the pressure sleeve 2 is accessible.
  • the pressure sleeve 2 can thus be removed on the delivery side 10.2 of the transport unit 10.
  • the pressure sleeve 2 can be pushed by the receiving means 11 onto the sleeve receptacle 6.1 of the printing machine 6 in accordance with a removal 106 of the printing sleeve 2.
  • the pressing sleeve 2 is partially supported by the receiving means 11 and partially through the sleeve receptacle 6.1 of the printing machine 6. Then, the method can be repeated accordingly for the next printing sleeve 2 on the trolley 8.
  • FIG. 5 shows a transport unit 10 of a system 5 in a partial view with a pressure sleeve 2, which is mounted on a receiving means 11 and wherein the receiving means 11 is supported by a second closure element 22 of a closure unit 20.
  • the transport unit 10 has a positioning aid 12, which is in particular an optical positioning aid.
  • a light beam in particular a laser beam, is emitted by the positioning aid 12, so that a relative relationship of the transport unit 10 or the receiving means 11 to a sleeve receptacle 6.1 of a printing press 6 in a working position 4 can be determined.
  • an operator 9 has a simple orientation aid in order to be able to estimate geometrically the removal of the pressure sleeve 2 from the receiving means 11 and in particular the supply of the pressure sleeve 2 to the sleeve receptacle 6.1 of the printing machine 6.
  • FIG. 6 shows a first end 11.1 of a receiving means 11 in a schematic representation, wherein the first end 11.1 of the receiving means 11 by two pivot portions 23 of a first closure element 21 of a closure unit 20 is encompassed.
  • the pivoting sections 23 each have a guide region 23.1 through which the first end 11.1 of the receiving means 11 can be gripped by the first closure element 21 even if the receiving means 11 tilts on one side and thus a receiving region of the closure unit 20 is not concentric with the first end 11.1 the receiving means 11 is.
  • the guide region 23.1 in each case has a curved or oblique shape, so that the first end 11.1 is guided until it is preferably completely received by the first closure element 21.
  • the Figure 7a further shows a receiving means 11, which is designed as a receiving mandrel and thus has a rod-like longitudinal extent.
  • a pressure sleeve 2 rests with a lateral surface 2.2, a passage opening 2.1 of the pressure sleeve 2 on the receiving means 11, so that an outer region of the pressure sleeve 2 is not contacted by the receiving means 11.
  • the receiving means 11 further has a Einfädelungs Scheme 11.4, which is at least partially formed obliquely, so that the pressure sleeve 2 is easier pushed onto the receiving means 11. Furthermore, in particular an exact positioning of the receiving means 11 may not be necessary.
  • the receiving means 11 has a slide coating 11.3, by which a frictional resistance between the pressure sleeve 2 and the receiving means 11 is reduced, so that pushing the pressure sleeve 2 on the receiving means 11 and a removal of the pressure sleeve 2 from the receiving means 11 for an operator 9 facilitates is.
  • FIG. 7b further shows a transport unit 10 with a receiving means 11, wherein a closure unit 20 of the transport unit 10 is shown in a supply state II.
  • the receiving means 11 is supported by a second closure element 22, wherein the second closure element 22 acts as a moment support for the receiving means 11.
  • the receiving means 11 tilts under its own weight along a direction of inclination 11.5 on one side downwards, since a first closure element 21 of the closure unit 20 is released from the receiving means 11.
  • the receiving means 11 accordingly tilts along a bending line.
  • the inclination along the inclination direction 11.5 is correspondingly greater when a pressure sleeve 2 rests on the receiving means 11 and thus also contributes by its weight at least partially to the bending line.
  • the first and / or the second closure element 21, 22 are corresponding to the Embodiment of FIG. 6 formed to compensate for the inclination of the receiving means 11 when the closure unit 20 closes.
  • FIG. 8 further shows a setup method 100 in a schematic representation of method steps in a further embodiment.
  • a transfer 101 of a closure unit 20 of a transport unit 10 from a security state I to a delivery state II is initially provided.
  • a receiving means 11 is closed by the closure unit 20 and in the feed state II a recording of a pressure sleeve 2 by the receiving means 11 is possible.
  • an application 102 in particular by pushing, the printing sleeve 2 from a feed position 3 on the receiving means 11 of the transport unit 10 and a transfer 103 of the closure unit 20 from the supply state II to the security state I.
  • the movement 104 comprises an alignment of the receiving means 11 at the feed position 3 and / or an alignment of the receiving means 11 at the working position 4.
  • a checking 105 of the closure unit 20 from the security state I to a delivery state III can take place, in which the pressure sleeve 2 in the receiving means 11 can be removed so that removal 106 of the pressure sleeve 2 can take place from the receiving means 11 and the pressure sleeve 2 are moved to the working position 4 can.
