Definitions
- the invention relates to a device for changing a pressure cylinder sleeve in a printing press with a frame that has a drive side and an operator side and in which a pressure cylinder sleeve receiving cylinder core is mounted so that the pressure cylinder sleeve axially to the operating side pull off, and arranged with a on the drive side of the frame Ejector and / or arranged on the drive side of the frame Retracting claw, releasably in a recess at the edge of the pressure cylinder sleeve intervenes.
- the clichés are on a printing cylinder sleeve or a so-called sleeve, which is detachable on a pressure cylinder core is deferred.
- the change can of the sleeve in the machine frame, so that the pressure cylinder core in the frame can remain.
- the sleeve only needs to be removed removed the bearing for the cylinder core located on the operating side become.
- the cylinder core is then cantilevered by that on the opposite Page held camp held.
- EP-A-0 053 791 describes a device for attaching a sleeve on a pressure cylinder core and for releasing the sleeve from the cylinder core, at an ejector acts on the end face of the sleeve.
- the object of the invention is to provide a device which allows the replacement the printing cylinder sleeve further facilitated.
- the bearings for the pressure cylinder core are mounted on slides that allow it. to turn on the impression cylinder to the impression cylinder.
- the ejector and / or the remindziehkralle is in relation to the machine frame in a position arranged on or near one through the axis of the cylinder core going and parallel to the trajectory of the carriage running Straight line lies.
- For the change of the printing cylinder sleeve can then be the cylinder core position it with the aid of the carriage so that the end face of the Pressure cylinder sleeve comes in a position opposite to the ejector.
- Different diameters of the cylinder core and / or the pressure cylinder sleeve can then bill by appropriate positioning of the carriage be worn so that it is possible, the ejector or the remindziehkralle stationary to be arranged on the machine frame.
- drive side in this application is the side of the printing press frame referred to, which is opposite to the operating side. Usually on this page also the drive for the various cylinders of the printing press arranged. However, this is not a necessary feature of the invention.
- Figure 1 shows a view on the operating side of a flexographic printing machine, i. on the side from which operating operations such as replacing a printing cylinder sleeve can be made.
- the printing press has a frame 10 which is formed by two side parts 12 and 14, In Figure 1, only the side part 12 can be seen. Between the side parts 12 and 14, a counter-pressure cylinder 16 is mounted, on the circumference of several inking units 18 are arranged.
- Each inking unit 18 includes a printing cylinder 20 and an applicator roller 22.
- a solid 24 recessed, through which the ends of the printing cylinder 20 and the applicator roll 22 are accessible.
- the impression cylinder 20 and the applicator rollers 22 are single stored in carriages 26 and 28, which are independently longitudinal guide rails 30 are movable.
- the guide rails 30 are each below the associated window 24 on the inside of the side part 12 and 14th appropriate.
- On the operator side are the bearings for the impression cylinder 20 and the Mandatory rollers 22 designed as a folding bearing or removable bearings.
- Figures 1 and 2a show the printing press in the state in which the printing cylinder 20 is employed at the periphery of the impression cylinder 16 and the Application roller 22 is employed at the periphery of the printing cylinder 20.
- FIG 2b the printing cylinder 20 and the applicator roller 22 by means of the carriage 26th and 28 have been returned to their parked positions.
- the diameter of the printing cylinder 20 varies according to the respective one Print job prescribed print length.
- the drives for the slides 26 are based on the known diameter of the printing cylinder 20 so controlled, that the outer peripheral edge of the printing cylinder on the applicator roll 22 facing side always with the ejection and retraction device 32nd is aligned.
- the bearing for the printing cylinder 20 on the operating side (on the side part 12) axially of the Axis of the printing cylinder has been deducted, so that it with the help of the carriage 26 can be moved to the side, as Figure 2c shows.
- the printing cylinder is then due to the dual storage on the opposite side cantilever-like held on the side part 14.
- the printing cylinder 20 has a cylinder core 36, on which a clichés carrying pressure cylinder sleeve 38th is deferred.
- the pressure cylinder sleeve 38 is removed with the aid of the ejection and retractor 32 a piece moved on the Zylinderkem 36 been so that they are conveniently accessible on the operating page in the window 24 and then easily by hand or with the help of a robot can pull off completely from the cylinder core 36.
- An actuating cylinder 40 is fixedly mounted on the console 34.
- the free end of the Piston rod of this actuating cylinder 40 forms an ejector 42 for the printing cylinder sleeve 38.
- a retracting claw 44 is hinged to the ejector 42 and pivotable by means of a smaller actuating cylinder 46. If the ejector 42 abuts against the end face of the pressure cylinder sleeve 38 and the actuating cylinder 46 is extended, the pull-back claw 44 engages with its hook-shaped cranked end in a hole 48, the near the edge in the pressure cylinder sleeve 38 is formed.
- the impression cylinder 20 is arranged with respect to the ejector 42 that this only the pressure cylinder sleeve 38 but not the cylinder core 36 acted upon. If the printing cylinder sleeve 38 is to be removed from the cylinder core, so is first in a known manner, the interior of the cylinder core 36 with compressed air applied. The pressure acts through holes 50 in the cylinder core on the inside the pressure cylinder sleeve 38, so that it is slightly widened and can be moved easily on the cylinder core. Subsequently, with Help the actuating cylinder 40 of the ejector 42 extended so that he the pressure cylinder sleeve a piece far away from the cylinder core 36, as shown in Figure 4 is. However, the remindziehkralle 44 remains in the dissolved state, so that The cylinder sleeve can be further pulled off by hand.
- FIG. 5 schematically shows an interior view of the side part 14 of the frame 10. It recognizes a part of the window 24 and a portion of the guide rail 30, on which the carriage 26 is guided.
- the Double bearing 52 mounted for the printing cylinder.
- the cylinder core 36 and the Pressure cylinder sleeve 38 are shown in phantom.
- the ejection and retractor 32 is on the same Height as the axis defined by the double bearing 52 axis of the printing cylinder.
- the drive of the carriage 26 is by means of an electronic control unit 54, in which the diameter of the impression cylinder is entered, so controlled that the ejector 42, the pressure cylinder sleeve 38 is applied but not the End face of the cylinder core 36.
- the ejector and retractor could 32 also arranged at the top or bottom vertex of the printing cylinder his. In this case, however, it would have to be adjustable in height to to allow adaptation to different diameters of the printing cylinder.
