Definitions

  • the invention relates to a printing unit for rotary printing presses according to the preamble of claim 1.
  • the lateral pins of the forme cylinder and the blanket cylinder of an offset printing machine with roller bearings are mounted in side frames. Outside the latter, races (bearer rings) are attached to the pins, while support rings are mounted on the pins inside the walls, which do not follow the rotation of the cylinders.
  • the main bearings are arranged in bushes with an eccentric outer surface, which form the power-operated device and can be rotated in the sense of turning the cylinder on and off and can be fixed in a position in which the desired preload force results. In this device, however, a gap adjustment after touching the support body is not possible.
  • the purpose of such a printing unit training should therefore only be to provide a support for printing unit cylinders which fulfills a function corresponding to the bearer ring operation, but offers better repair conditions.
  • a printing machine which has an adjusting device for an offset cylinder in order to bring it into working contact with a forme cylinder and a printing cylinder one after the other.
  • the offset cylinder is supported by roller bearings on an axis on which cam disks are attached on both sides of the cylinder.
  • Each cam disc is held in the operating position by means of a pressure roller in contact with two fixed rollers which are supported by eccentric pins fastened in the side walls of the machine frame.
  • the axis on which the cam disks are seated can be rotated by means of an adjusting device by specific, predetermined angular amounts.
  • the adjustment device contains a rotatable cam, which is scanned by a roller at the end of an angle lever.
  • a roller at the other end of the bell crank rests on a lever that acts on an arm attached to the axis of the offset cylinder via an adjusting screw.
  • the cam discs on the axis of the offset cylinder are shaped on their circumference in such a way that when the adjustment device rotates, radial displacements of the cylinder axis result, in order to thereby move the offset cylinder one after the other towards the forme cylinder and towards the impression cylinder.
  • Such an adjusting device is exclusively for displacements of the offset cylinder itself, without there being any connection with the other two cylinders.
  • the adjustment movement of the offset cylinder occurs solely with reference to parts attached to the side walls of the machine. It is therefore carried out completely independently of the other cylinders and regardless of their position.
  • the publication does not say what elements and how these other cylinders are held and supported.
  • the problems that can be identified from the above statements are to be solved as far as possible.
  • the invention wants to create the conditions for a real "kiss print” and thus for a perfect print result, in particular for indirect letterpress printing, but also for other printing processes that previously had difficulties in achieving a perfect print image, primarily with regard to on the color transfer.
  • the aim is to bring the color as close as possible to the «point» or to concentrate there primarily and to pass it on while maintaining this condition in order to achieve a correspondingly good result .
  • the way to this is to dispense with the hitherto usual pressures between two cylinders with the resulting hard shoulder, possibly with the exception of the relation between an impression cylinder and a transfer cylinder in a printing unit for offset or dry offset.
  • a printing unit is provided according to the invention in which the important cylinders have a high degree of accuracy and in which there are sensitive adjustment options.
  • Such a printing unit has the features specified in the characterizing part of claim 1.
  • the cylinder referred to in the claims as the first cylinder is advantageously a transfer cylinder and the second cylinder is a forme cylinder.
  • the support bodies can have any shape that is suitable for a perfect positioning of the parts of the system in the sense of the invention.
  • plates, extension pieces, brackets, trestles and similar elements can be provided as supporting bodies, which have corresponding surfaces as supporting surfaces on the bodies lying opposite each other.
  • the support bodies are advantageously in the form of rings or disks, in particular with a cylindrical peripheral surface, possibly also with flat portions.
  • a pair of support bodies means those that are arranged parallel and at an axial distance from one another, for example the support bodies associated with the second cylinder and arranged on both sides thereof.
  • the adjustability of the position of the support surfaces means that the radial position of the respective support point for the adjacent support body can be changed with reference to the axis of the associated cylinder (center of rotation) or, if the support body for the further support of the two-point system is concerned, with reference to an imaginary line or axis directed essentially parallel to a cylinder axis.
  • the position of the supporting surfaces of the same can expediently be set independently of one another. However, a common adjustability is not excluded.
  • support bodies are provided on the first cylinder, the support surfaces of which have a fixed distance from the axis of rotation of the cylinder, in particular in the form of rings or disks with a cylindrical peripheral surface attached to the axis of the cylinder as the support surface.
  • Support bodies with an adjustable position of the support surfaces are then assigned to the second cylinder.
  • the position of the support surfaces can either be fixed or else adjustable, depending on the circumstances or the other design of the printing unit.
  • the latter applies in particular to a very inexpensive version of the printing unit, in which the further support surfaces are assigned to a third cylinder which cooperates with the first cylinder.
  • This third cylinder is advantageously a forme cylinder. If the second cylinder is also a forme cylinder, this represents a particularly advantageous embodiment of a printing unit for indirect high pressure, in which the two forme cylinders then work together with a transfer cylinder, specifically with different circumferential areas of the latter.
  • this is also expediently rotatably mounted on one axis with roller bearings, the support bodies being carried by this axis.
  • An advantageous embodiment with the possibility of adjustment consists in that at least one support body can be adjusted in angle by means of an adjusting device about an axis of rotation and has a support surface lying eccentrically to this axis of rotation.
  • the axis of rotation is expediently equal to the center of the axis of the cylinder.
  • the support body is advantageously rotatably mounted on the cylinder axis, in particular by means of a preloaded roller bearing.
  • the term mentioned should also include those peripheral surfaces whose distance from the axis of rotation changes continuously, for example following a spiral, or, if appropriate, also in steps.
  • An expedient embodiment of an adjusting device for a support body rotatable at an angle contains a worm drive, the worm wheel of which is connected to the support body in a rotationally fixed manner.
  • a worm drive the worm wheel of which is connected to the support body in a rotationally fixed manner.
  • the worm of the worm drive is supported on the side facing away from the worm wheel on two thrust pieces, which are under the force of springs that seek to move against one another, namely disk springs.
  • the worm is constantly pressed into the gears of the worm wheel and the worm drive is kept free of play in a simple manner, so that precise adjustments are possible in both directions.
  • Such a design of a worm drive is of independent importance beyond its use in an adjusting device for a support body, in particular for other movement or setting devices in printing machines.
  • the invention provides that the ends of the axis of the first cylinder are received by fork-shaped ends of two pivot levers mounted on frame parts, the other ends of which are connected to the power-operated device used to move the levers and thus the cylinder.
  • the pivot points of the levers lie in the area between their ends, and advantageously at such points that the movement of the cylinder axis or the support body carried thereby takes place essentially symmetrically to the two contact points.
  • the printing unit can also be designed in such a way that the first cylinder is assigned a counter-pressure cylinder with support bodies which are intended to bear against the support bodies of the first cylinder, the counter-pressure cylinder being movable relative to the first cylinder in the sense of starting and stopping.
  • a design can be considered for various printing processes. It is particularly suitable for a printing unit for indirect high pressure, in which case the first cylinder is a transfer cylinder.
  • the impression cylinder is advantageously also rotatably mounted on an axis with roller bearings, the support bodies being carried by this axis, be it in the sense of a fixed connection or be it using a rotary bearing. The latter is particularly suitable when it comes to adjustable support bodies, as is advantageous in many cases.
  • an expedient embodiment also consists in the fact that the support bodies of the counter-pressure cylinder have support surfaces extending eccentrically to the center of rotation of the cylinder and that the angle around the center of rotation can be adjusted.
  • the impression cylinder can in particular be held in two levers which can be pivoted with a power-operated device in the sense of turning the impression cylinder on and off. It is advantageous that a device for moving the first cylinder and a device for moving the counter-pressure cylinder can be actuated in succession in a predetermined sequence by means of a control device. This can also be carried out automatically using the means available to the person skilled in the art.
  • roller bearings are advantageously preloaded. This also helps to increase accuracy.
  • a particularly favorable design of a roller bearing for the cylinder bearing arrangement consists in that the roller bodies are arranged on a helix at a distance from one another in a cylindrical cage. The bearing can then also contain an outer ring and an inner ring in the usual way.
  • flow paths for a medium for influencing the temperature are provided in at least one cylinder.
  • a medium is especially oil.
  • the cylinder can thereby be cooled if necessary or, for. B. in the start-up phase of the printing press, are also heated so that an at least largely constant temperature can be maintained during operation, which additionally has a favorable effect on the accuracy.
  • An expedient embodiment consists in particular in the fact that bores are provided in both ends of the axis of a cylinder and open into the interior between the cylinder and the axis in the vicinity of the mounting of the cylinder, the cylinder being sealed on the outside on both sides thereof.
  • a control or regulating device is expediently provided for maintaining a predeterminable temperature of the medium passed through the cylinder. This can be a common device for several cylinders. However, a separate device is particularly advantageously provided for each cylinder that can be influenced by temperature.
  • the invention is further directed to the manufacture of a cylinder for a printing unit of the type described, which consists in that the cylinder with the roller bearings is mounted on the axis, in particular with installation of the bearing under preload, and that the cylinder afterwards with the axis under tension Rotation around this is ground on its peripheral surface.
  • the axis can be clamped in the usual way on a grinding machine.
  • Such a finish machining of the cylinder in its already finally stored state on the axle enables an extraordinarily high shape Accuracy and also achieve a corresponding surface quality.
  • a printing press for indirect high pressure is shown, which is equipped with three printing units D in the inventive design.
  • a line B drawn in dash-dot lines running through the printing units in succession can thus be printed in six colors.
  • Each printing unit contains a transfer cylinder 1, two forme cylinders 2 and 3 which cooperate with it and an impression cylinder 4 which cooperates with the transfer cylinder at another point.
  • the letter F denotes the inking units 2 and 3 assigned to the forme cylinders.
  • Web B can be, for example, a multi-layer web for adhesive labels, in which, following the printing process, a die-cutting process and possibly other treatment processes are carried out.
  • the web B can be moved by means not belonging to the invention in the area of the printing press in such a way that continuous overprints are produced on the web, although the transfer cylinder only has a surface intended for printing on parts of its circumference, the form cylinders being designed accordingly and with Printing plates are equipped in such a way that such areas arise on the transfer cylinder.
