Definitions

  • blowing devices work satisfactorily in straight printing. However, they are unsuitable for improving the register-containing removal of a turned sheet from the upstream printing cylinder by means of suction cups, grippers or the like arranged on the sheet turning cylinder, or also unsuitable for enabling the wrinkle-free transfer to the subsequent printing unit of the sheet already turned.
  • a disadvantage of these devices is that the mechanical means, if there are no pressure-free corridors, always blur or impair the printed image.
  • the advantage of the invention is that the force of flowing air can be used to press a sheet onto the impression cylinder not only in face printing but also in perfecting, which was not previously possible.
  • a sheet-turning cylinder 3 is arranged between a printing cylinder 1 and printing cylinder 2 of successive printing units.
  • the diameter of this cylinder is equal to the diameter of the impression cylinders 1, 2 and twice as large as the diameter of the other cylinders.
  • two suction systems 8, 10 and two gripper systems 9, 11 are also arranged diametrically on a shaft rotatably mounted eccentrically to the axis of the sheet turning cylinder 3.
  • Fig. 1 it can be seen how the sheet 13 rests on the closed surface of the printing cylinder 1.
  • the front edge of the sheet 13 has been guided over the tangent point 12 by the grippers of the gripper system 4 and the end of the sheet has reached the tangent point.
  • Suction cups 16 of the suction system 8 suck the bow end from the surface of the printing cylinder 1 immediately before or at the tangent point 12 and the grippers of the gripper system 4 of the printing cylinder 1 release the sheet 13.
  • the suction system 8 and the gripper system 9 are swung during the further rotation of the cylinders 1, 2, 3 onto the center of the sheet turning cylinder 3 and towards one another in a known manner.
  • the bow 13 is during the further rotation of the cylinders 1, 2, 3 by the grippers of the gripper system 9 accepted. After the transfer, both systems 8, 9 are swung back into the starting position in a known manner.
  • the arch 13 is thus turned and is guided by the gripper system 9 with the trailing edge first to the subsequent tangent point. There, the sheet 13 is transferred from the gripper system 9 to the gripper system 6 of the printing cylinder 2.
  • the gripper system 6 of the printing cylinder 2 leads the turned sheet 13 to the following printing unit for printing on the back of the sheet.
  • a sheet following the sheet 13 during the printing process is in the same way by the corresponding sheet guide systems arranged diametrically to the described system, i.e. the gripper system 5 on the pressure cylinder 1, the suction system 10 and the gripper system 11 on the sheet turning cylinder 3 and the gripper system 7 on the pressure cylinder 2 through the machine.
  • a device which has a blowing finger support tube 15 which runs axially parallel above the printing cylinder 1 and extends over the entire length of the printing cylinder 1.
  • Blown fingers 14 are arranged on the blower finger support tube 15 at a distance from one another, the area with their lower air outlet surfaces 18 and air outlet openings 17 into the transfer zone up to the tangent point 12 between the suction devices 16 of the gripper systems 8; 10 are performed.
  • the air outlet surface 18 is adapted to the contour of the printing cylinder 1, so that there is a constant gap width.
  • the device according to the invention is lifted out of the transfer area by means of an adjusting device 19 and it can be lowered again by means of the same device in the case of perfecting.
  • the coupling gear provided for this purpose is shown schematically in FIG. 4.
  • the adjusting device 19 each has an angled support bracket 23 which is fastened with one arm to the respective end of the blowing finger support tube 15.
  • a groove curve 24 is incorporated, which slides on a bolt 21 fixed to the frame.
  • a hand lever 25 is further articulated by means of a swivel joint 27, which has a bolt 20 fixed to the frame.
  • the device By pivoting the hand lever 25 counter-clockwise around the bolt 20 fixed to the frame, the device can be lifted from the working position perfecting together with the blowing fingers 14 into the position 14 'shown in dashed lines in Figure 2'.
  • a pushing movement is superimposed on the circular pivoting movement of the hand lever 25 by the groove curve 24 and the bolt 21 fixed to the frame.
  • the device according to the invention can be lowered back into the working position perfecting and printing in the transfer area directly to the tangent point 12.
  • the air flow indicated by arrows in FIGS. 2 and 3 is fed via an air supply pipe 29 to a block 28 which is seated on the blowing finger support pipe 15.
  • the blower finger support tube 15 is provided with an opening at this point, so that the air flow supplied can get into the blower finger support tube 15 and further via bores 32 into the cavity 31 of the blow finger 14.
  • the amount of air flow is adjustable, e.g. by a control valve (not shown in more detail) or by a throttle valve 30 interposed in the air supply pipe 29.
  • the sheet turning cylinder 3 also regularly has recesses 26 distributed over the circumference across the width of the turning cylinder so that a collision with the tip of the blowing fingers 14 is avoided in the working position perfecting. If the blowing fingers 14 the gripper systems 9; 11 to be arranged opposite one another, these gripper systems 9 and 11 must also have swung in time in the direction of the center of the sheet-turning cylinder 3 during the rotation of the drum, in order to print in perfecting, ie in the Working position to avoid the collision with the blowing fingers 14. This can be achieved in a known manner by extending the corresponding curve section of the control curve. Collisions with the blower fingers 14 in straight printing are not possible, since in this operating mode of the printing press the device has to be lifted from the transfer area beforehand by means of the adjusting device 19.
