Definitions

  • the invention relates to a device for exposing printing plates of a printing unit.
  • the exposure of such printing plates is usually carried out using a laser device, wherein the laser beams act on the printing plate such that their surface in the printing unit receives the ink according to the printed image to be produced.
  • a negative or positive of the printed image to be produced the latter may be an image, a font or other representation.
  • certain parts of the surface may be repelled for the ink and other surface areas may accept the ink.
  • the negative or the positive of the printed image is then formed by appropriate distribution of these different surface properties on the printing plate.
  • the printing plate is exposed to exposure to laser radiation, which generally operates by displacing the printing plate carried by a cylinder in an exposure station on the one hand and the laser optics on the other during the exposure process relatively both in the longitudinal direction of the cylinder as well as in the circumferential direction of the cylinder, the latter being preferably effected by a rotation of the cylinder about its longitudinal axis, while the linear relative movement between cylinder and laser optics in the majority of cases is brought about by a linear displacement of the laser optics.
  • EP 0 981 895 B1 is mentioned as state of the art.
  • a disadvantage of known devices for exposing printing plates of a printing unit is that they do not work very economically. This arises once from the fact that the laser device during the time required for the replacement of the printing plates in the exposure station, not working, so it can not be used. These shutdown times for the laser device can be up to 50% of the total operating time, since between the exposure treatments of two successive printing plates first removed the exposed printing plate of the just ended exposure treatment from the exposure station and introduced the printing plate for the subsequent exposure treatment in the station and at the therein located bracket must be attached. The time required for this is particularly significant when the substantially cylindrical pressure plate with the actual plate cylinder, which also carries the printing plate in the respective printing unit, inserted into the exposure station and thus exposed sitting on the plate cylinder.
  • the invention has the object of providing a device according to the preamble of claim 1 in such a way that it at least largely avoids the disadvantages of known devices and enables efficient use of the laser device in particular. Furthermore, the device should have the simplest possible structure and be used without any special difficulties.
  • the teaching of the invention can be summarized to the effect that two exposure stations associated with a common laser device is moved between the two stations such that when in one station, the exposure of the pressure plate located there takes place in the other station, the printing plates or the plate cylinders are replaced.
  • printing plates and plate cylinders are easily accessible, since the laser optics and this carrying carriage are then in the other treatment station.
  • the time required for the treatment of a printing plate in the respective treatment station depends on a certain size of the printing plate or the printed image in addition to other factors in particular also on the speed at which the cylinder carrying the printing plate is rotated.
  • the rotational speed and thus the resulting peripheral speed of the cylinder or the pressure plate carried by it are certain limits set for technical reasons.
  • many of the known exposure devices operate at rotational speeds for the cylinder carrying the printing plate, some of which are well below the speeds which would be possible with respect to the laser treatment of the printing plate.
  • This limitation of the speed is due, inter alia, to the fact that the axle or shaft carrying the cylinder is only supported at one end, that is to say it is cantilevered.
  • each treatment station is provided with a support element for the axle or shaft carrying the respective cylinder and the support element between a first position in which it is the shaft or axle supports near one end thereof, and a second position in which it releases the shaft or axis, is displaceable.
  • the shaft or axle which carries the pressure plate receiving cylinder, thus at least during the exposure treatment at both ends supportable, so that higher rotational speeds, for example 1200 U / m are possible without undue vibrations occur, which in the exposure to inaccuracies in the Processing can lead by laser, which then inevitably affect the quality of the printed image on the object to be printed.
  • the higher rotational speed also allows a correspondingly higher speed with which the laser optics is moved along the cylinder.
  • the cylinder-carrying part is referred to as a shaft, without being associated with a restriction to those components which are used to transmit a torque serve. Rather, such cylinders are also included in the scope of the invention, for example, at both ends each carrying a stub axle, of which only one serves to transmit a torque. On the other hand, hollow cylinders fall within the scope of the invention, which are pushed onto a shaft mounted in the respective exposure station.
  • the embodiment shown in the drawing is provided with a table-like base 10, which has two stands 12 at its two front ends, which are each provided with a bearing for an axle section 14.
  • the two axle sections which can be rotated about their common longitudinal axis, carry a plate-like holder 16, which carries a carriage 17, which is displaceable parallel to the longitudinal axis of rotation of the holder 16, with an exposure unit which is provided with a laser optical system 18.
  • the laser diodes and other parts of the exposure unit are not shown separately, since they are familiar to any person skilled in the art and are not required for the understanding of the invention.
  • the energy is supplied to the exposure unit by means of an energy supply chain 26, which bridges the distance between the exposure unit and an energy source, not shown, in the course of the linear movement of the exposure unit.
  • an exposure station 28 and 30 On each longitudinal side of the base 10 is an exposure station 28 and 30, each with a holder 31 and 32 for a plate cylinder 35 and 36, respectively, in which the respective plate cylinder is positioned such that its axis of rotation is parallel to the axis about which the carriage 17 can be pivoted back and forth with exposure unit.
  • the two holders 31 and 32 for the plate cylinder are arranged in relation to the laser optics 18 of the exposure unit such that the laser optics 18 in their two operating positions, in which the treatment of the pressure plate 34 of the respective plate cylinder 35 and 36, respectively in a short Distance from this also cylindrical pressure plate 34 is located.
  • Figures 1 to 3 show one of the two treatment positions of the exposure unit in which the printing plate 34 of the plate cylinder 36 located in the station 30 is treated by means of laser beams.
  • the laser beams act on the printing plate of the plate cylinder 35 located in the station 28.
  • the laser optics 18 is positioned at a short distance from this likewise cylindrical pressure plate.
  • the control carriage 37 carries at its upper end a roller 44 which engages in a located at a front end of the plate-shaped holder 16 wall portion 45 curve 48 such that a horizontal movement of the control carriage 37 from the end position shown in FIGS. 1 and 3 to the left in the other end position shown in Fig. 8 causes a pivoting of the holder 16 by about 90 °, in the course of the laser optics 18 passes from the exposure station 30 in the exposure station 28.
  • the embodiment shown in the drawing is intended for the handling of hollow plate cylinders which are provided with a coaxial through hole 50 ( Figure 5).
  • the holder 31, 32 located in each of the two exposure stations 28, 30 thus has a shaft 52 whose outer diameter is adapted to the inner diameter of the hole 50 in the respective plate cylinder, so that the plate cylinder in each case from the position shown in FIG. 5 in the direction of arrow 53 on the Shaft 52 can be pushed into the position shown in FIG. 2.
  • the shaft 52 is arranged cantilevered such that it is mounted at one end in a bearing unit 54, wherein the free end 56 of the shaft faces the frontal boundary of the device on which the control slide 37 is arranged.
  • the drive of the shafts 52 is effected by a common electric motor 58 to which each of the two shafts 52 is connected by means of a belt drive.
  • a common electric motor 58 to which each of the two shafts 52 is connected by means of a belt drive.
  • Fig. 5 of the drawing only one of the two belt drives 60 is shown.
  • each of the two shafts 52 is assigned a unspecified coupling, by means of which the respective shaft is rotated or stopped.
  • Each shaft 52 is near hers provided free end with a roller bearing 62, the function of which will become apparent from the following description.
  • Each of the two brackets 31, 32 is provided with an up and down movable support member for the respective shaft 52.
  • This support element is formed as part of a support slide 66 which can be moved up and down, which has a cutout 64 on the upper side which is adapted to the cross-sectional dimensions of the respective rolling bearing 62.
  • the two support carriages 66 are arranged relative to the respective associated shaft 52 such that the respective support carriage 66 in its upper, operative position comprises the lower cross-section of the shaft in the region in which the roller bearing 62 is arranged.
  • fitting pieces 68 are movably arranged on the support slide 66 such that they can be pivoted between the opened position shown in FIGS. 6 and 7 and the closed, effective position shown in the station 28 in FIGS. 1, 3 and 8, in which they embrace the upper cross-sectional area of the respective shaft 52.
  • Each fitting 68 is mounted, with the interposition of spring means 71, preferably at least two disc spring assemblies, to one support member 75 ( Figure 6) which is pivotally connected to the upper end of the support carriage 66 and pivotally connected to the end of an actuation rod 84.
  • fitting pieces 68 ensures that they fit snugly against the shaft 52 so as to ensure the most accurate possible storage of the same during the exposure process, without the stroke exerted by the associated actuating rod correspond exactly to the pivoting movement of the fitting piece 68 got to.
  • the fitting pieces 68 are pivotally mounted in the plane in which also extends the support portion forming cutout 64 so that they rest in its closed position also on the outer ring of the mounted on the shaft 52 roller bearing 62.
  • the up and down movements of the support carriage 66 and the pivoting movements of the two fitting pieces 68 are each effected by a toggle lever 70 which is provided at its the two lever members 72, 74 connecting joint 76 with a cam roller 78.
  • the operation of the toggle lever 70 is effected by a respective control cam 80.
  • Both cams 80 are each mounted with the interposition of a spring means 71 (FIGS. 7 and 8) on the control carriage 37.

  • FIG. 4 also shows that the movement of the control carriage 37 in the direction of the arrow 86 due to the engagement of the cam roller 44 in the attached to the holder 16 curve 48 simultaneously causes a pivoting of the holder 16 with the laser optics such that the latter from the exposure station 30 is moved in the direction of the other exposure station 28.
  • Fig. 4 shows an intermediate position of the control carriage 37 about half way from its right end position to its left end position, in which the cam roller 78 of the right toggle lever 70 out of engagement with the associated curve 80 on the control carriage 37 and the cam roller 78 of the left toggle lever comes into engagement with the associated curve 80.
  • the laser optics 18 is at the lower vertex of its pivotal movement between the two exposure stations.
  • a measuring cell can be arranged at the base of the device, which is opposite to the laser optics located in the lower vertex of the pivoting path and serves to test the diodes located in the laser carriage. It is possible to briefly interrupt the movement of the control slide 37 and thus the pivotal movement of the laser optics for this test by appropriate control of the drive motor 38. The time required for this is so small that it is negligible, especially since the testing of the diodes is required only at certain time intervals, ie not at every pivoting movement of the laser optics.
  • the knee lever 70 assigned to the station 28 is brought into or almost into its extended position, which is shown on the left in FIG.
  • the associated support slide 66 is first moved to its upper end position, wherein the end region with the bearing 62 of the cylinder 35 bearing shaft 52 engages with the cutout 64 of the support slide 66, whose upper end position is determined by the stop 92.
  • the last phase causes the movement to the left end position, which is shown in FIG is, a further upward movement of the intermediate member 81, which is bounded by the stop pins 94, which come in the course of this further upward movement of the intermediate element on the support carriage 66 to the plant.
  • this last phase of the movement which is limited by the stop pins 94, the displacement of the rods 84, which pivot the fitting pieces 68 in their closed position shown in Fig. 8 on the left, in which they enclose the shaft 52 on the upper side.

  • the central drive with electric motor 38, spindle 40 and spindle nut 42 biases the entire system with the force of the respective effective spring 43 between the spindle nut 42 and control slide 37.
  • the biasing force on the bracket 16 is then the force of the respective effective spring 43 less the force of the respective effective spring 71 between the control slide 37 and the respective curve 80.
