The Hubarmeinrichtung 14 allows a displacement of the removable roller 1 between a working position I and a storage position III.

The roll changing device further comprises a storage device 17 for mounting the Hubarmeinrichtung 14 in a pivotable manner about a pivot axis S, which is substantially parallel to the axis of rotation of the roller to be changed 1 is aligned. The pivot axis S passes through an intermediate region, which is located in the vertical direction between the working position I and the storage position III of the removable roller.

The storage facility 17 for mounting the Hubarmeinrichtung 14 is on the side frame of the printing press 13 assembled. The left lift arm structure 15 and the right lift arm structure 16 are formed such that the radial distance of the exchange roller 1 from the pivot axis S can be changed by appropriate control of the roll changing device.

The pivot axis S is located above the working position I of the changing roller I. For lifting the removable roller 1 become the two Hubarmstrukturen 15 . 16 retracted, so that the change roller 1 the pivot axis S approaches.

After complete retraction of the removable roller 1 can the Hubarmstruktur 15 . 16 be pivoted about the pivot axis S, so that the Changing roller here comes into positions II or IV. In these positions II or IV, the changing roller can optionally be treated automatically, in particular cleaned.

Lifting the removable roller 1 takes place by being grasped in the region of its axial ends. The lifting arm structures 15 . 16 For this purpose, they are provided in the area of their outer ends with gripping structures for gripping the replacement roller.

The lifting arm structures 15 . 16 can form part of a multi-arm lifting arm star. The Hubarmstrukturen are executed in the embodiment shown as a telescopic cylinder.

The sheet-fed press equipped with the aforementioned roll changing device 13 is in the area of the bearing point of the removable roller 1 provided with a clamping device which can be selectively brought into a clamping position and in a release position. In the clamping position is the removable roller 1 secured in that working position I in a rotatably movable manner.

It is possible to design and arrange the cylinder so that it passes through the pivot axis S and rearwardly over the hub area 15N protrudes. The projection can be dimensioned so that this almost the radial distance of the tip of the gripping head 18 from the pivot axis S in the retracted state corresponds.

In 3b is a two-armed variant of the Hubarmsystems shown. The lifting arms 15A . 15B are arranged diametrically opposite each other.

3c shows a three-armed variant. The lifting arms 15A . 15B and 15C are at the same circumferential pitch at the hub area 15N appropriate. It is possible to otherwise define the pitch and thus correlate certain rotational positions of the Hubarmsystems and positions of transfer and possibly treatment stations.

In 3d is a three-armed variant shown. In particular, in this variant, the Hubarmsystem can act as an intermediate magazine, in which three rollers can be stored and still a Hubarmpaar for lifting the roller from the working position is available.

In 4 is sketchy the position of a Einarmsystems after 3a displayed within a printing press. The lifting arms adjacent to the A and B side frames 15 . 16 are over a crossbeam 19 connected with each other. The crossbar 19 is here designed as a relatively torsionally rigid structure and extends concentrically to the pivot axis S. The cross-beam 19 can also be designed as a bow-like structure, in this case on a lifting arms 15 . 16 opposite side extends offset towards the rear relative to the pivot axis.

It is possible in the crossbeam 19 to incorporate a pivot drive, via which, for example via a torsion cylinder, a required to pivot the Hubarmportals drive torque can be applied.

The inventive device is particularly suitable for the use in sheet-fed rotary printing presses with flexographic printing or Coater in chamber doctor blade / screen rolling technology. It is suitable furthermore in particular for Sheet-fed offset printing presses with upstream, downstream and intermediate coating or Flexowerken for inline finishing on or before a pre-coating.
