Definitions

  • the invention relates to a method for aligning sheets after the side edge, in which the sheets to be aligned are conveyed within a scattering area on a feed table on which the actual position of the side edge determined by a measuring device and the respective foremost sheet detected by a Bogenbeschreibungsvorraum and the Gripper system is fed to a drum, wherein the gripper system for the realization of the desired position of the side edge, which, objectified by an approximately centrally provided in the scattering range side draw line, can be moved in the axial direction.
  • a sheet transported by the sheet accelerating device from the feed table to the gripper system of the drum is brought into the desired position by axial displacement of the gripper system with respect to the side edge and then transferred to the gripper device of a downstream cylinder.
  • the gripper system and the gripping device come too close to the sheet transfer in large drawing paths, so that it comes in the processing of thick substrates to impermissible bow deformations.
  • Another way to eliminate these disadvantages is to make the distances between the grippers of the gripper system and the grippers of the gripping device large and the width of the gripper low. However, this requires a poor bowing, which leads to an increased spoilage and business interruptions.
  • the object of the invention is to provide a method for aligning sheets, which can be realized with little effort and increases the productivity of a printing press.
  • the object is achieved by a method according to the features of claim 1.
  • the inventive solution it is possible to make the distances of the intermeshing sheet holding systems so that without height adjustment of sheet holding systems, a sheet guide can be realized, which ensures trouble-free sheet travel even with problematic substrates.
  • FIG. 1 shows a sheet-fed system consisting of a feed table 1 with front marks 2 located in a position on the feed table 1, a sheet accelerating device 3, which is designed as a vibration system 4, a drum 5 with a gripper system 6 and a cylinder 7 arranged downstream of the drum 5, which is equipped with a gripping device 8, shown.
  • the oscillating system 4 has a vibrating gripper system 9, which consists of gripper fingers 10 and a gripper bar 11, wherein the vibrating gripper system 9 is associated frame-fixed the vibrating system 4.
  • the gripper system 6 of the drum 5 is provided in the axial direction displaceable in the drum 5 and consists of grippers 14, which cooperate with gripper clutches 15.
  • the feed table 1 is shown with a bow 16 and a follower sheet 17. From the feed table 1 only in the sheet conveying direction 18 on the left side - one side I - located half is shown. On the opposite side there is a page II.
  • the sheets 16,17 are transported in the sheet conveying direction 18 on the feed table 1.
  • a measuring device 21 is slidably and lockably provided in a measuring device 21 is slidably and lockably provided. The measuring device 21 can be moved within the format range 20 to be set to the formats to be processed.
  • the measuring device 21 extends at least over a scattering area 22 and is connected to an evaluation unit, not shown.
  • the scattering area 22 is the area in which the side edges of the sheets reaching the processing can run in, so that their actual position can still be reliably detected and brought into a desired position.
  • the desired position is identical to the position of a side draw line 23, which is provided approximately centrally in the scattering region 22.
  • FIG. 3 shows different patterns of interlocking sheet holding systems.
  • FIG. 3a shows the oscillating gripper system 9, the gripper system 6 of the downstream drum 5 and the gripping device 8 of the cylinder 7.
  • the gripper system 6 of the drum 5 does not perform any axial movement for aligning with the side edge.
  • the gripper fingers 10, gripper 14 and sheet gripper 12 have a width a, while between the gripper fingers 10, the grippers 14 or the sheet grippers 12, a distance b is provided. Between two interengaging sheet holding systems 9,6,8 a system distance c is provided. In this case, the system distance c is chosen so that the resulting during the transfer / acquisition deformations of the material to be processed are so small that the productivity of the printing press is not adversely affected. In the acquisition / transfer of the bow, the gripper fingers 10 / gripper 14 and gripper 14 / sheet gripper 12 are arranged centrally to each other.
  • FIG. 3b shows the state of the art in which the gripper system 6 of the drum 5 is displaced axially in order to be able to align the sheet-like material to be processed for processing with one side edge.
  • the grippers 14 of the gripper system 6 are arranged in the sheet transfer centered on the gripper fingers 10 of the vibratory gripper system 9 and can subsequently from its center position X a maximum of a pulling path Z 2 in the direction of page I or page II.
  • the gripper system 6 is moved in the direction of the side II. After realization of a maximum pulling distance Z 2 the arcuate processing material held by the gripper system 6 is transferred to the gripping device 8 and subsequently the gripper system 6 is returned to its starting position (middle position X).
  • the width a of the gripper fingers 10, the gripper 14 and the sheet gripper 12 to the maximum pulling distance Z 2 decreases and so does the distance b around Z 2 increased.
  • the sheet-shaped printing material is transferred from the grippers 14 of the gripper system 6 to the gripping device 8 of the cylinder 7. Thereafter, the gripper system 6 is not returned to a central position (center position X) to the oscillating gripper system 9, but moved to a different position to take over the subsequent sheet-shaped substrate.
  • This takeover position results from the fact that by the measuring device 21 in the feed table 1 and the evaluation unit from the actual position and the target position for the subsequent sheet-shaped printing material to be realized by the gripper system 6 pulling path by amount and direction is determined.
  • the printing material is taken over by the gripper system 6 from the oscillating gripper system 9 and subsequently displaced during transport to the gripping device 8, the gripper system 6 by the amount determined by the measuring device 21 / evaluation and thus realizes the desired position.
  • an arc 16 and a subsequent arc 17, as shown in the embodiment in Fig. 2 the procedure is as follows.
  • the sheets 16,17 are promoted to the feed table 1, that the side edges within the scattering range 22, which is identical to the maximum pull Z, shrink.
  • the desired position is objectified by the side-line 23. In order for the sheet 16 to move from the actual position to the desired position, a partial drawing path e 1 must be realized, the drawing direction being directed to the side-drawing line 23.
  • the follower sheet 17 must cover a partial pulling path e 2 for realizing the desired position, wherein the pulling direction is likewise directed to the side draw line 23.
  • the sheet 16 is taken over by the gripper system and this moved in the axial direction and in the direction of the side line 23 and the side I to the partial pulling path e 1 , so that the sheet 16 is brought into the desired position. Subsequently, the sheet 16 is transferred to the gripping device 8.
  • the actual position of the subsequent sheet 17 is detected by the measuring device 21 and a pulling path e 2 and the drawing direction, which is directed away from the side I and directed to the side-pull line 23, detected.
  • the gripper system 6 initiated by the downstream of the measuring device 21 evaluation unit, the transfer position for the subsequent sheet 17 is controlled.
  • the takeover position is again eccentric to the partial Ziehweg e 2 2 spaced from the side-pull line 23. In this takeover position, the
