Definitions

  • the invention relates to a register feed device for sheet-fed printing and embossing machines with front edge stops and side stop or side shift. If a sheet with a first printed image from a previous printing process is to be provided with a second printed image or embossed subject in a later subsequent printing or embossing process, the position of the second image for each individual sheet must match the first image exactly with this . In practice, however, various register errors can occur, as a result of which the second printed image is shifted from the first. This means that the first print image, the position of which is defined by print marks, is not exactly aligned with respect to the sheet edges and that, above all, not all sheets have the same register errors, but that these errors can vary from sheet to sheet.
  • register errors arise, for example, when cutting the sheets from a web-fed printing press or during a first printing process in a sheet-fed printing press, if there are differences in the image distance from the sheet edges as a result of operating errors, inaccurate settings or operational disturbances.
  • these register errors occur a very big problem.
  • sloping leading edges with an angular deviation in relation to the print mark positions could not be corrected correctly.
  • the registers were set as optimally as possible manually at the beginning of a printing or embossing process and were no longer changed during the printing process. In the best case, with very slow, continuously occurring deviations, readjustment by hand to a very limited extent. Correcting single sheets in this way is not possible in this previous way.
  • this should be done with a relatively simple and safe working, practice-oriented procedure.
  • an inventive register pull-in device according to claim 1.
  • the arrival of the sheet is determined at the two front edge stops with position detectors and then both stops are moved in the direction of travel X until the front print marks have reached their desired positions and the front edge is accordingly correctly aligned.
  • the sheet is then moved in the transverse direction by the side stop or sideshift until the side print mark has reached its desired position, so that all the print marks are now in the desired position, ie the leading edge and side edge are aligned correctly.
  • the sheet is gripped with the gripper bar and used for further processing drawn into the printing or embossing machine.
  • the embossed subject then exactly matches the first printed image, so that the highest quality can be achieved for each individual sheet.
  • YL 1 mm with unchanged image edge error Y3 of 0.4 mm.
  • FIG. 3 schematically illustrates a register pulling-in and correction device according to the invention
  • FIG. 5 shows the associated chronological sequence in this new method
  • the sheet runs in at a constant speed of, for example, 0.3 m / s in direction X until it hits stop A1 at time T1.
  • the arrival of the sheet edge at the stops A1, A2 is determined by position detectors D1 and D2, preferably attached to them.
  • the stops A1, A2 are then moved until the position sensors S1, S2 detect the assigned front print marks P1, P2 at the time TS1 or TS2.
  • the side shift of the stop or slide A3 then begins at time T4, for example by pulling the sheet in the Y direction, until the position sensor S3 detects the associated page print mark P3, which determines the page correction value Y3.
  • the gripper bar 8 (FIG. 6a) grips the sheet, which is now correctly aligned, in the desired position P1S, P2S, P3S.
  • the displacement of the front stops can only begin after the front edge 51 has arrived at both stops A1, A2 or, if 51 and A1 and A2 do not arrive at the same time, their displacements can also start individually, staggered as soon as the front edge 51 has reached the stop in question.
  • the sheet 5 is still held in contact with the stops A1, A2 by suitable conveying elements 15 (in FIG. 6).
  • any suitable positions on the print image can also be selected as print marks, the assigned sensor (here S1a for mark P1a) on the holder 12 (FIG. 6) being set accordingly.
  • a side stop A4 is drawn in on the right in FIG. 3, which would push the sheet in the Y direction.
  • the left stop A3 pulls, then e.g. in the form of a clamping slide, the bow in the Y direction.
  • the stops A1, A2, A3 and A4 are controlled by actuators M1, M2, M3 and M4 and can be moved with an accuracy of at least 0.1 mm.
  • Suitable actuators are e.g. ac servo motors with spindles or rack, as well as linear motors.
  • Cam disks 24, 25 are also suitable, as shown in FIGS. 6, 7, in which the maximum linear displacements in the X and Y directions are given and limited by the curve stroke.
  • Figure 4 shows a circuit diagram of the register device according to the invention with a system control 11 with a computer, which with the machine control 7 of a downstream printing or embossing machine 1 (in Fig. 8) and with the position sensors S1, S2, S3, the position detectors D1, D2 and the actuators M1, M2, M3 is connected.
  • An operating and display unit 9 allows e.g. also the ongoing control of the edge errors X1, X2, Y3 as well as the acquisition and statistical evaluation of operating data.
  • FIG. 6a shows a side view
  • FIG. 6b shows a top view of a register pulling device, which accepts sheets from a feeder 3, aligns them correctly and then transfers them to the gripper bar 8 in a correct target position for further processing in a printing or embossing machine 1.
  • the sheet 5 is conveyed by a belt as a transport device 14 to the front stops A1, A2, where detectors D1, D2 determine the arrival of the sheet.
  • detectors can be equipped, for example, with precisely adjusted photo cells, generally with optoelectronic or also with electromechanical elements.
  • the position sensors S1, S2, S3 are here on one hinged frame 13 attached, on which they are adjustable and fixed in the X and Y directions exactly on the assigned print marks P1, P2, P3 of a flawless reference sheet and fixed.
  • the front stops A1, A2 with the detectors D1, D2 are here mounted on a bar 20, the ends 21, 22 of which can be displaced in the X direction by the actuators M1, M2.
  • the actuators here consist of servomotors 23 and flat cam slides 24. The displacements become corresponding to the geometric arrangement, ie the distances on the Y axis from printing marks P1, P2 to the adjacent end 21 or 22 and the distance between the ends 21, 22 the actuators are converted by a system controller 11 (FIG.
  • FIG. 7 shows a side shift design in which the side stop A3 can be designed either as a slider 19 for pulling the sheet in the Y direction on the left sheet edge 52 or as a "real" stop 28 for pushing on the right sheet edge 53.
  • a servo motor 23 serves as the actuator and drives cylinder cam disks 25 which can be displaced thereon via a spline shaft 26.
  • the sheet is held in place by a holding element 32, e.g. pressed by means of a pneumatically movable plunger 17. This holding element 32 is also controlled and actuated by the system controller 11.
  • FIG. 8 shows a printing and embossing machine 1 with a feeder 3, a register station 10 according to the invention, a press 2 and a delivery arm 4.
  • a gripper bar 8 grips the sheet 5 in a corrected correct target position and feeds it to the press 2.
  • a panel 9 also contains displays and controls for the register retraction and correction device 10.
  • the register insertion and correction device for sheet-printing and embossing machines with two front edge stops and side stop or side shift has position sensors S1, S2, S3 for detecting print marks P1, P2, P3 of the sheet (5) and two assigned to the front stops A1, A2 Detectors D1, D2 for detecting the front edge of the sheet (51).
  • the front stops A1, A2 can be adjusted by actuators M1, M2 until the front printing marks P1, P2 of the sheet are detected by the corresponding sensors S1, S2. Above all, oblique leading edges with angular errors W are corrected perfectly.
  • An actuator M3 then adjusts the side stop or side opener A3 until the side print mark P3 is detected by the assigned position sensor S3.
  • a system controller (11) controls this register correction with the position sensors S1, S2, S3, the detectors D1, D2 and the actuators M1, M2, M3. This results in a simple, reliable automatic register correction for each individual sheet and thus consistently the highest print quality.
