  • the plate on the plate cylinder must be correctly aligned.
  • the pressure plate must be axially adjustable relative to the substrate used.
  • the plate is typically first attached to the plate cylinder, and then the entire plate cylinder is axially displaced to achieve proper axial alignment.
  • the present invention has for its object to provide a plate cylinder, which allows the alignment of a printing plate or multiple printing plates in a simple manner to provide the provision of an external alignment device and a method for aligning printing plates on a plate cylinder.
  • An inventive plate cylinder comprises the features of claim 1.
  • a spring member cooperating with a rotatable actuator permits axial displacement of the register pin or tabs in the gap when the actuator is in a first position and allows the registration pins to be locked in the gap when the actuator is connected, preferably by a known tensioning shaft is formed, in a second position.
  • the plate cylinder is preferably a multiple plate cylinder having at least two independently movable register pins.
  • the register pin can be fitted in a gap of a spring element.
  • the spring element preferably consists of two separate springs, the first being of low rigidity and the second of higher rigidity.
  • the first spring of low rigidity opposes the displacement of the pin a small resistance, so that a controlled axial movement of the pin in the gap from the outside by means of the external alignment device can be realized.
  • the second spring of higher rigidity is deformed by the rotation of the actuator to fix the register pin for the printing operation in the gap position stable.
  • the actuator is preferably an eccentrically mounted clamping shaft.
  • the plate cylinder is preferably provided with register holes or markings to allow for correct placement of the external alignment device.
  • the printing machine is preferably an offset printing press that includes a blanket cylinder cooperating with the plate cylinder.
  • the simple construction of the plate is particularly advantageous when used in conjunction with a sleeve-shaped blanket finds application as z. B. in the US 5,429,048 is described.
  • the base is preferably secured to the plate cylinder using locating pins that cooperate with locating holes provided in the plate cylinder.
  • the base may be magnetic so that it can be held firmly and accurately positioned on the plate cylinder during the alignment adjustment.
  • the pin slide is preferably axially displaceable relative to the base by means of an actuating drive.
  • the pin valve can have the function of a nut through an internally threaded bore, whereas an axially extending rod is provided with external thread and serves as a screw or threaded spindle.
  • a knob can be attached to fine tune the rotational position of the rod. In this way, the pin valve by means of rotation of the knob with a very high accuracy z. B. in the micrometer range axially adjustable, so as to move the register pin in view of a desired change of the page register.
  • the present invention further provides a method for aligning plates on a plate cylinder comprising the steps mentioned in claim 12.
  • the dowel pin or register pin engages in the subsequently mounted on the printing plate cylinder pressure plate in a hole formed in the pressure plate or notch.
  • a plurality of printing plates is mounted on the plate cylinder, wherein the plates in the axial direction are preferably spaced from each other spatially.
  • Fig. 1 shows a plate cylinder 10 according to the present invention, wherein the plate cylinder 10 is adapted to receive four printing plates, of which the plates 2, 3 are shown.
  • the plate cylinder 10 includes four register pins 12, 13, 14, 15 axially slidable in a gap 20, the gap 20 being in the outer surface of the cylinder 10 and serving to receive the angled ends of a printing plate inserted into the gap and in this z. B. be held by clamping.
  • Fig. 2 shows the printing cylinder 10 in a sectional view along the section line AA in Fig. 1
  • the registration pin 14 is inserted into the gap 20 (eg, by inserting it endwise) such that its head portion 16 fits within the gap 20 and its rear portion 18 opposite the head portion 16 extends out of the gap 20 into an axially extending bore 30 of the plate cylinder 10 extends into it.
  • the rear portion 18 extends through an opening provided in a first spring 41 opening 43 (FIG. Fig. 5 ), wherein the spring is disposed in the bore 30.
  • a second spring 42 of lesser spring stiffness than the spring 41 which preferably has a high spring stiffness, rests against the side wall of the bore 30 and bends between the base of the spring 41 and the rear portion 18 in such a manner that the rear end 18 is urged out of the gap 20 into the interior of the bore 30.
  • Fig. 5 shows a possible embodiment of the register pin 14, which preferably has a curved head portion 16 which is guided during assembly through the opening 43 of the first spring 41 with little play so that its extending beyond the head portion 16 extending wings 26 at the Support spring 41.
  • a tensioning shaft in the form of a cam or eccentric 50 which by a rotating device 52, as in Fig. 1 shown, can be rotated.
  • the rotating device 52 may be either detachably connected to, or inseparably connected to, the rod 50 by, for example, a keyed connection.
  • the device 52 is manually or mechanically operable.
  • the spring mechanism 40 which, as in Fig. 2 shown, the first and second springs 41 and 42, acts such that the pin 14 in the in Fig. 2 shown position of the rod 50 is axially displaceable, but against a slight resistance.
  • the pin 14 is locked.
  • the rod 50 extends through the entire plate cylinder 10 through and locked in this way each of the register pins 12, 13, 14, 15 or releases them.
  • the plates 2, 3 and two further plates can be mounted on the plate cylinder 10. Due to the interaction of recesses (register punches) 112, 103 in the pressure plates 2, 3 with the register pins 12 and 13 are the plates 2, 3 in a correct axially aligned, register-containing position.
  • the fastening of the pressure plates 2, 3 can be effected, for example, by a plate clamping mechanism provided in the gap 20.
  • the plates 2, 3 may have an angled leading edge which is inserted into the gap 20 at its sharp leading edge 67, as in FIG Fig. 3 shown, wherein the rest of the plate wraps around the circumference of the plate cylinder 10.
  • the rear edge of a printing plate can then be inserted into the gap on the register pins and z. B. also be secured by the disc clamping mechanism, or it remains unpaved.
  • FIG. 10 shows an external alignment device 70 according to the present invention which serves to displace one of the registration pins 12, 13, 14, 15 when the rod 50 is in an unlocked position.
  • the device 70 has a base 71 in which a threaded spindle 72 preferably having a fine thread is rotatably mounted is.
