Definitions
- the invention relates to a protective device of a cylinder of a printing press according to the preamble of claims 1 or 9.
- DE 196 03 666 C2 discloses a protective device on forme cylinders, which is designed to be pivotable by rotating the eccentric bearing bushes.
- the invention has for its object to provide a protective device for a cylinder of a printing press.
- the advantages which can be achieved with the invention consist in particular in protecting against inadvertent contact with rotating cylinder parts when changing the printing plate.
- the protective device is not connected to eccentric bushings, so that no corresponding gear is required to compensate for different swiveling movements.
- FIG. 1 is a side view of a printing unit in a basic representation with two removable and adjustable plate cylinders, in which the first plate cylinder is in a print-down position and the associated cover is open;
- FIG. 2 shows an illustration analogous to FIG. 1, but the first plate cylinder is in the print-on position when the cover is closed;
- FIG. 3 is an illustration analogous to FIG. 1, but the second plate cylinder is in a print-down position, the associated cover being open;
- FIG. 4 shows a section IV-IV of the first plate cylinder according to FIG. 3, an upper spacer 22 and the associated holding roller 17 being omitted;
- Fig. 5 shows a section V - V of FIG. 2 in an enlarged partial view.
- a printing unit e.g. B. for flexographic printing, consists of two cylinders 01 each equipped with printing plates; 02, e.g. B. printing or forme cylinders 01; 02, which together or separately on a cylinder 03, z. B. an impression cylinder 03 and a roller 04, z. B. anilox roller 04 are adjustable.
- the predominantly separate employment of the forme cylinder 01; 02 is carried out by means of eccentric bearing bushes 06 (Fig. 4). This results in a pressure-on position A or a pressure-off position B of the forme cylinder 01; 02.
- the anilox roller 04 is connected to an inking device, not shown. All cylinders 01; 02; 03 and roller 04 are separate, e.g. B. driven by means of drive motors, not shown.
- a protective device 07 for the forme cylinder 01 or 02 consists of a rotatable ring 08, to which a jacket-shaped or channel-shaped cover 09 is attached.
- the cover 09 envelops approximately half the circumference of the forme cylinder 01 or 02.
- the ring 08 carries the jacket-shaped cover 09 on its inner circumference 11.
- the ring 08 has two annular beads 13; 14, between which, as seen in the circumferential direction of the ring 08, a toothing 16 or the like is arranged.
- the ring 08 is used by several, e.g. B. four approximately evenly arranged on the circumference of the ring 08 holding rollers 17.
- the outer edges of the ring bead 13 act; 14 against a groove-like tread 18 on the circumference of the holding rollers 17, side walls 19; 21 secure the respective ring 08 against axial displacement.
- the holding rollers 17 are, for. B. at the free end of a spacer 22 is mounted on a side frame 23.
- the periphery of the forme cylinder 01 or 02 is in a parked state, i.e. in print-down position B at a minimum distance c and in an engaged state, d. H. removed in the print-on position A at a maximum distance d from the cover 09 (FIG. 3).
- the ring 08 can be rotated manually or by means of a pinion 24 which engages in the toothing 16 and which is driven by a drive motor 26 which is fixed to the side frame. H. is twisted.
- Each cover 09 of the protective device 07 can be rotated in two positions: cover 09 "open in position E or cover 09" closed “in position F, as seen from the operating side.
- the second forme cylinder 02 is in the print-down position B, the cover 09 being in the "up” position E.
- a plate change can take place, etc.
- the cover 09 can only be turned to the open position B in position E “up”.
- the cover 09 has its own actuator, which independently of an actuator for starting and stopping a cylinder 01; 02 can be actuated.
- the cover 09 in a gap between two cylinders 01, 03; 02, 03 or in a gap between a cylinder and a roller 01, 04; 02; 04 are brought.
- two blanket cylinders can each work according to the imprinter principle against a counter-pressure cylinder, one for each blanket cylinder swiveling form cylinder belongs.
- each rubber igniter has an analog protective device 07. This can be rotated so that when the molded igniter 01; 02 and rotating rubber cylinder each rubber cylinder in the handling area is covered.
- Each cover 09 is expediently supported at both ends, that is to say from both sides, with a ring 08 and the associated holding rollers 17 which are fixed to the side parts.
