Definitions

the present invention relates to a printing unit mounted on a machine frame and comprising a back pressure cylinder, a printing cylinder adjustably spaced from said back pressure cylinder, and an inking roller included in an inking device and adjustably spaced from said printing cylinder, said printing cylinder and said inking roller being mounted in bearing brackets resting upon an arm on the machine frame and urgeable, by interposition of exchangeable gauge blocks, into pressure contact with a machine frame surface and the printing cylinder bearing brackets, respectively, by means of a power unit.
DE Patent 27 46 878 where the pressure contact is established during operation of the printing unit by means of a cylinder assembly hingedly connected to the machine frame arm and actuating a lever which, in its turn, is pivotally mounted in said arm and hingedly connected to a guide.
the guide can be clamped by means of a clamping device to a bar connected to the rear ends of the bearing brackets of the inking roller.
this object is achieved in that the contact pressure exerted by the power unit has its contact points in the machine frame within the region of the machine frame surface.
a back pressure cylinder 1 is rotatably mounted in a machine frame 2 which has an arm 3 carrying bearing brackets 4 for a printing cylinder 5 rotatably mounted in said bearing brackets 4. Further bearing brackets 6 are mounted on the machine frame arm 3 to carry the inking device of the printing unit.
the printing unit comprises an inking roller 7 cooperating with the printing cylinder 5 and engaging, in its turn, a fountain roller which dips into an ink container 9.
the fountain roller 8 is mounted in the bearing brackets 6 by means of swivel arms 28.
the web of material 10 travels'between the back pressure cylinder 1 and the printing cylinder 5.
the machine frame 2 has a frame surface 11 against which the bearing brackets 4 of the printing cylinder can be urged by interposition of gauge blocks 12 corresponding to the diameters of the cylinders 1 and 5, said bearing brackets 4 being displaceably carried on the machine frame arm 3.
the bearing brackets 6 of the inking roller 7, on their part, can be urged against the bearing brackets 4 by interposition of gauge blocks 13 corresponding to the diameters of the printing cylinder 5 and the inking roller 7, said bearing brackets 6 also being displaceably carried on the arm 3.
each chain 15 is adjustably clamped at one end in the machine frame 2 by means of a self-locking eccentric lock 16.
the other end of each chain 15 is connected to one-arm of a lever 17 pivotally mounted in the machine frame 2 and having its other arm hingedly connected to the-piston rod of a pneumatic or hydraulic cylinder 18, the cylinder end of which is hingedly connected to the machine frame 2.
each chain 15 is passed around the bearing brackets 4 and 6 via upper and lower guide pulleys 19 and 20 rotatably mounted on the bearing brackets 6 of the inking roller 7.
the lower guide pulley 20 is mounted in an eccentric bush 21 which can be rotated to permit adjustable tensioning of the associated chain 15.
the chain 15 is tensioned via the lever 17 around the guide pulleys 19 and 20.
the contact pressure exerted by the cylinder 18 has its contact points in the machine frame 2 within the region of the frame surface 11, such that the arm 3 is entirely relieved of the contact pressure, and the bearing brackets 4 and 6 will be entirely independent of any support by the arm 3.
the nominal spacings between the rollers and the cylinders 1, 5 and 7 can be set exactly by means of the gauge blocks 12 and 13 in combination with the contact pressure of the bearing brackets 4 and 6 against one another and against the machine frame surface 11.
the printing cylinder 5 and the inking roller 7 are mounted in eccentric bushes 22 and 23 connected each to one lever 24 and 25.
the free ends of said levers 24 and 25 are hingedly connected to adjusting devices 26 and 27 with micrometer screws for precise adjustment.
a further advantage of the printing unit according to the invention is that its printing cylinder can be readily exchanged for another printing cylinder of different diameter.
the eccentric lock 16 is unlocked by means of a suitable tool, whereupon the chain 15 is slackened by the required amount.
the return movement made possible by the cylinder stroke can be adjusted by means of the eccentrically mounted guide pulley 20.
the so-called minus stroke of the cylinder 18 is set, via the guide pulley 20, to maximum value.
the eccentric lock 16 is opened.
the adjusting device 26 is removed from the machine frame 2, and the bearing brackets 4 and 6 can then be pulled back. If then also the adjusting device 27 is removed, the printing cylinder 5 with its bearing brackets 6 sits loosely on the machine frame arm 3 and can easily be dismounted. If the roller or cylinder diameter is changed, different gauge blocks must be mounted. After that, the bearing brackets are again moved together until the inherent springiness of the bearing brackets 4 begins to resist.
the eccentric lock 16 is locked and the cylinder 18 is moved in the opposite direction. Also the eccentrically mounted guide pulley 20 is turned to tension the chain 15. Using this guide pulley 20 to limit-the stroke of the cylinder 18 is expedient in order to ensure that the spring force in the released position of the printing cylinder 5, when the machine is inoperative, can keep the bearing brackets 4 in position.
