Definitions

  • the invention relates to a printing plate clamping device for a flexible printing plate provided with receiving holes at the front and rear end section for a plate cylinder of an offset printing machine.
  • the printing plate clamping device essentially consists of flat strips extending along the channel of the plate cylinder, the top surfaces of which lie essentially parallel to the surfaces of the clamped end sections of the printing plate, a first and a second, each assigned to an end section of the printing plate, with hooks for engaging in the receiving holes provided, essentially flat and arranged above a bar, a first and a second pivot connection, each arranged in the area of the longitudinal center of a tensioning rail, between a tensioning rail and a bar underneath with guide elements which are essentially perpendicular to the cover surfaces of the bars for a displacement of at least one tensioning rail in the axial and circumferential direction of the plate cylinder, an eccentric adjustment device for displacement of at least one tensioning rail in the axial direction of the plate cylinder and on the tensioning rails attacking clamping means for clamping the pressure plate
  • the printing plates applied to the plate cylinder are generally designed as foils, which are given the properties required for the offset process via an etching device.
  • the pressure plates are clamped at their ends by means of clamping rails which are arranged in the channel of the plate cylinder and are adjustable in the circumferential and longitudinal directions of the plate cylinder.
  • clamping rails which are arranged in the channel of the plate cylinder and are adjustable in the circumferential and longitudinal directions of the plate cylinder.
  • tensioning screws are provided for this purpose, by means of which a tensioning rail is pressed off a wall of the channel, and laterally fitted adjusting screws, by means of which the tensioning rail is adjustable in its longitudinal direction.
  • one of the front and rear edges of the pressure plate is assigned to the tensioning rail by means of a swivel plate which can be actuated by screws and is provided with a return spring, in each case in the direction of the other tensioning rail, the The tensioning effect of the swivel plates is transmitted to the tensioning rail via pins attached thereto and the tensioning rails can be swiveled around said pins, while the swivel plates are articulated via a swivel axis arranged in the longitudinal direction of the channel of the plate cylinder to a bar which also extends along the channel is in turn displaceable in the longitudinal direction of the channel by means of an eccentric adjustment device.
  • the screws provided for tensioning the pressure plate naturally require a fixed abutment on the plate cylinder, which, in particular in the known exemplary embodiment according to CH-A-300 967, entails additional material expenditure and impairment of the accessibility to the tensioning rails. Furthermore, when using a plurality of tensioning screws arranged along the channel, tensioning in the pressure plate can be caused according to said embodiment.
  • the object of the invention to provide a device of the type mentioned, the tensioning rails are easily accessible, which enables tension-free tensioning of the printing plate and whose adjustment mechanisms are subject to a reduced functional impairment due to contamination.
  • Tension springs as tensioning means can retain the advantages of automatic tensioning of the pressure plate, which is not influenced by manual screwing operations, while at the same time saving installation space and with lower requirements for the streakiness of tensioning rails.
  • the required installation space which increases the accessibility and makes it more difficult to swivel in the radial direction to the plate cylinder, is avoided with the associated abutments, and not only the mentioned disadvantageous effects of progressive soiling are reduced, but also by means of the beads provided on the strips and tensioning rails in the of Areas of the device affected by relative movements are prevented by the cleaning effect of these beads from heavier soiling of said areas.
  • the individual paper sheets 3 are fed from a paper stack 1 via a separating device 2 into the gap between the blanket cylinder 4 and the impression cylinder 5, where the printing process takes place.
  • the paper sheet 3 printed in this way is then gripped by a chain delivery 7 provided with gripper rows 6 and fed to a delivery stack 8.
  • the plate cylinder 12 is assigned an applicator roller 11, which is connected to a dampening unit 9 and an inking unit 10.
  • a rubber blanket washing device 13 is assigned to the blanket cylinder 4, while an etching device 15 is provided for the printing plate 14, and a feed device 16 can also be assigned to the plate cylinder 12.
  • the pressure plate 14 is fastened on the plate cylinder 12 by means of a tensioning device 17 for its front edge 21 and a further tensioning device 18 for its rear edge 22.
  • a control panel 19 provided with appropriate keyboards is used to operate the machine.
  • Fig. 2 shows an enlarged view of the plate cylinder 12 with clamping devices 17, 18, with its contours and the plate cylinder longitudinal axis 30 are indicated.
  • the tensioning device 17 for the pressure plate front edge 21 initially consists of a base plate 24 which partially covers the cylinder channel 23 and which is connected to the plate cylinder 12 via screw connections 25.
  • a threaded bolt 27 protrudes from the surface of the bottom plate 24 in the area of the plate cylinder center line 26 and serves as a fulcrum for a tensioning rail 29 provided on the bottom plate 24 and provided with hooks 28.
  • the threaded bolt 27 protruding through a bore 32 of this tensioning rail 29 is provided at its upper end with a nut 33 with associated locking washer 34 and washer 31 in order to hold the tensioning rail 29.
  • the tensioning rail 29, which can be pivoted diagonally to the plate cylinder longitudinal direction in this way, can be locked in an axially parallel position via an additional locking device 36 attached to it. Among other things, this facilitates the clamping of the pressure plate 14.
  • the clamping rail 29 has a web 37 in this area via a right-angled bend.
  • a locking lever 39 is fastened to this by means of screw 38, nut 33 and locking washer 34 (see also FIG. 4).
  • This is T-shaped and pivotable about the pivot point 40 formed by the screw 38.
  • His shaft 41 engages in a u.a. 2 visible recess 42 of the bottom plate 24.
  • This in turn has a narrow area 43 and a wide area 44.
  • the shaft 41 engages in the narrow region 43 of this recess 42, which is of the same width, which is equivalent to a locking of the tensioning rail 29 in an axially parallel orientation.
  • this locking is released and, due to the wide area 44 of the recess 42, a certain scope for a rotary movement of the tensioning rail 29 around the pivot point created by the threaded bolt 27 is possible.
  • FIGS. 3 and 5 show views of the tensioning device 18, which cooperates with the tensioning device 17 for the pressure plate front edge 21, for the rear edge 22 thereof. This in turn is also equipped with a tensioning rail 45 provided with hooks 46.
  • FIG. 3 shows the adjustment mechanism for lateral adjustment of this tensioning rail 45, ie in the longitudinal direction of the cylinder.
  • a floor plate 47 covering it is also provided in this area of the cylinder channel 23.
  • a lower bar 48 and an overlying upper bar 49, as will be shown later, are arranged thereon so as to be movable relative to one another.
  • a threaded bolt 50 is attached to the upper bar 49, which produces the connection to the tensioning rail 45 via a nut 33 and a locking washer 34, but a mutual one Rotatability about the threaded bolt 50 is retained as the axis of rotation.
  • Beads 35 provided on both strips 48, 49 in turn also serve to smoothly move and prevent excessive contamination.
  • an eccentric 54 is connected to the lower bar 48 and has an adjusting lever 55.
  • This eccentric 54 which can be rotated around the threaded bolt 51 as a fulcrum, protrudes from a recess 56 of the upper bar 49 corresponding to the eccentric cross section.
  • connection mechanisms between the base plate 47 and the two strips 48, 49 are shown, as is the spring-loaded tensioning mechanism for tensioning the pressure plate 14 on the plate cylinder 12.
  • the other end 72 holds a pin 61.
  • This bolt 61 which is held by means of the locking ring 62 and the disk 63, projects through an elongated hole 64 of the base plate 47 directed in the cylinder circumferential direction and is fastened to the lower bar 48.
  • a further bolt 66 is attached to this, which protrudes through an elongated hole 67 of the upper bar 49, which is directed in the longitudinal direction of the cylinder, and is also provided with a washer 63 and a locking ring 62.
  • a web 68 created by right-angled bending of the lower bar 48 enables the tensioning rail 45 to be actuated manually against the spring force of the tension springs 58, for example for hanging the pressure plate 14.
  • the tensioning rail 45 designed in this way is thus displaceable in the longitudinal direction of the cylinder and furthermore has degrees of freedom which allow an accompanying inclined adjustment with respect to the longitudinal direction of the cylinder and a tensioning movement in the circumferential direction of the cylinder, because via the bolts 61, 66 with the corresponding elongated holes 64, 67, in which they are guided, as well as via the eccentric 54 and the threaded bolt 50, the following forces or movements are transmitted to the tensioning rail 45: the tensioning force of the tension springs 58 with an accompanying tensioning movement directed in the cylinder circumferential direction (elongated hole 64).
  • a transverse movement (elongated hole 67) directed in the longitudinal direction of the cylinder and triggered by the movement of the eccentric 54 by means of the adjusting lever 55, and a rotary movement of the tensioning rail 45 caused by the threaded bolt 50 acting as an axis of rotation.
  • the two tension springs 58 which are arranged symmetrically to the plate cylinder center line 26, are dimensioned such that owing to the spring forces, tearing out of the perforations of the pressure plate 14 cannot occur, so that their ideal abutment on the plate cylinder 12 at high printing speeds is still ensured, and at the same time an expansion compensation of the Printing plate 14 can take place during the printing process.
  • the procedure for adjusting and adjusting the applied pressure plate 14 is as follows: First, the axially parallel locking of the tensioning rail 29 is released via the locking lever 39; then the rear clamping rail 45 can be adjusted laterally by means of the adjusting lever 55 via the eccentric 54. This is accompanied by a corresponding oblique alignment of the tensioning rails 29 and 45 due to the degrees of freedom assigned to them. However, it is always ensured that, due to the tension springs 58 becoming effective, the pressure plate 14 remains tensioned over the cylinder surface with constant force.
  • the degrees of freedom in the movement of the rear tensioning rail 45 are composed of individual degrees of freedom of components (strips 48, 49 and tensioning rail 45) which are arranged in different planes 69, 70, 71 (FIGS. 3, 5).
