Definitions

  • the invention relates to a method and a device for braking the sheet in the delivery of a sheet-fed rotary printing machine according to the preamble of Claim 1.
  • Suction belts or are used to reduce the sheet speed in the delivery Suction rolls are known to work at a machine speed Rotate at a slower speed and suck up the bow.
  • From the DE-AS 21 35 105 it is also known to the incoming, initially at his front edge held by sheet grippers of a transport system on the whole To blow width with blowing air, which is opposite to the sheet and the out one immediately before the stack of sheets below the path of movement of the sheet arranged blow nozzle bar emerges.
  • blowing air which is opposite to the sheet and the out one immediately before the stack of sheets below the path of movement of the sheet arranged blow nozzle bar emerges.
  • the bow movement opposite air flow arises on the rear side of the blow molding sucking, thus frictional forces between the bow and the air blower causing negative pressure, so that braking forces on the meanwhile by the bow grippers the loosened sheet of the transport system.
  • the incoming sheets are slowed down by Machine speed to zero one after the other, so that the sheets subsequently are placed one after the other on the sheet stack in the delivery.
  • the one to slow down the consecutive arc available time is mandatory due to the consecutive braking extremely short, so that maximum possible Braking forces are necessary that act on the bow and this accordingly strong claim. This increases the susceptibility to faults and the possible Machine speed limited. Attempts to improve so far concerned the optimized design of the brake device means or the attachment of Emulation.
  • DE-A 39 38 863 shows a method for braking and stacking tabular bodies arranged in succession in a row translatory direction of movement are fed to a stack position, wherein in Area of a bow brake a scaling of the successive body takes place and in which a parallel to and below the body Blown air jet is used, the supply of the formed as an arc Body to the bow brake in the gripper closure and by means of a floating guide.
  • the airborne air is arranged by a number arranged side by side Axial fans with radially blowing air generated.
  • blowing devices arranged in the area of the sheet brake should pass through Vacuum applying the rear edge of the sheet to the braking device support.
  • the invention has for its object that for braking the sheet To enlarge available time windows in the machine cycle, so regardless of the machine speed, more time to brake each Winning bow.
  • the procedure for braking the sheets in the delivery can be carried out with braking devices acting mechanically on the sheet, for example Brake bands, suction rolls or the like, in connection with a mechanical Sheet transport system (gripper chains) for the sheets to the delivery, or preferably by means of a guide in the same direction as the sheet transport Air flow to slow down the arc.
  • braking devices acting mechanically on the sheet, for example Brake bands, suction rolls or the like, in connection with a mechanical Sheet transport system (gripper chains) for the sheets to the delivery, or preferably by means of a guide in the same direction as the sheet transport Air flow to slow down the arc.
  • the levitation, sheet brake and sheet stack arranged essentially on a level so that when processing thin flexible paper realizes a stack formation without wrinkling (crumpling) can be.
  • a mechanical conveyor system for the sheet transport from the last printing unit to Delivery of a sheet-fed rotary printing machine selected a mechanical conveyor system, in the case of gripper bridges 1 attached at the side to rotating conveyor chains at intervals are that extend across the sheet width and with a lateral distance from one another have sheet grippers 2 which hold the sheet 3 to be transported on it Detect the front edge and pull it over a floating guide 4, in the blowing air under the transported sheet is passed through openings 5 in the transport direction of the Sheet emerges and is thus directed towards the delivery pile. In the direction of transport is on At the end of this levitation guide 4, a sheet brake 6 immediately in front of the sheet stack 10 arranged.
  • the top 7 of the sheet brake 6 is located opposite one of the Path of motion 8 of the carrier air flow T carried on its transport Sheet 3 approximately the same, but preferably on the measure of the substrate thickness d lower level.
  • This makes it possible to use the front area Machine speed following sheet 3 over the rear area of the previous sheet 3a to pull, which is still on the sheet brake 6, the holds the sheet 3a in its rear area and with one opposite the Transport speed of the sheet 3 is operated at reduced speed. It this results in a time saving in the order of magnitude of the comparison of the Velocity-time diagrams in Figures 2 and 3 after a sheet braking the inventive method ( Figure 2) and a conventional Sheet braking ( Figure 3).
  • the one available for sheet braking Time window is increased considerably because the time of the sheet deceleration in the Area that can be extended by the overlap formed by the scaling.
  • the sheet brake 6 can be designed as a mechanical sheet brake and for example, from suction belts rotating side by side, a suction roller or the like exist, but with a compared to the speed of Sheet transport to the delivery runs at a lower speed.
  • the sheet brake 6 detects the sheet 3a in its rear area and at the same time forms an extension the levitation guide 4 for the following sheet 3, as can be seen clearly from the figure 1 results.
  • the sheet brake 6 is arranged at a distance a - seen in the sheet transport direction - behind the floating guide 4, so that an exhaust air duct 9 is formed between these devices, which derives the air flow T generated by the floating guide 4 as soon as the end of the respective leading sheet 3a Opening cross-section of the exhaust duct 9 releases.
  • the carrier air flow T is divided into two arms (T T , T A ). In this case, the air flow T T remaining between the bends 3 and 3a causes the separation of the successive bends 3, 3a, the other air flow T A being conducted into the exhaust air duct 9.
  • a sheet 3 fed to the delivery by means of a gripper closure is fed to the sheet brake 6 on a carrier air stream T.
  • the - seen in the sheet transport direction - arranged behind the levitation guide 4 sheet brake 6 is arranged essentially at the same level as the levitation guide 4, in a preferred embodiment, the height difference between the levitation guide 4 and sheet brake 6 is the substrate thickness d.
  • the distance a between the levitation guide 4 and the sheet brake 6 determines the outlet cross section of the exhaust air duct 9.
  • the sheet stack 10 is essentially with its storage surface (top sheet) arranged at a level with the levitation guide 4 and the sheet brake 6, preferably by the substrate thickness d lower than the sheet brake 6.
  • the floating guide becomes a carrier air flow T with at least one Speed components in the direction of movement of the bow 3,3a in the direction of Bow brake 6 rinsed.
  • This speed component has an amount of approx. 50% to 150% of the conveying speed of the sheet 3.3a.
  • the sheet 3 is held with its front edge in the gripper system 1, 2 and Sheet brake 6 supplied. This floats on a carrier air stream T at a distance H above the floating guide 4. At this time there is 6 on the sheet brake the leading sheet 3a, which is already at a reduced speed on the Sheet stack 10 is transported. This leading sheet 3a forms the Extension of the control level formed by the floating guide 4. Thus the Sheet 3 already drawn over sheet brake 6 without the sheet 3a leading ahead touch or without coming into contact with the sheet brake 6.
  • the leading sheet 3a releases the air outlet opening of the exhaust air duct 9.
  • the carrier air T is divided into a partial flow T A , which is discharged via the exhaust duct 9 and a partial flow T T , which ensures the separation between the two bends 3, 3 a.
  • the exhaust air duct 9 is completely released from the leading sheet 3a, so that the exhaust air flow T A becomes larger and the separation air flow T T becomes smaller.
  • one end of the sheet 3 reaches the sheet brake 6 released by the leading sheet 3a.
  • the gripper 2 opens and also releases the front edge of the sheet 3.
  • the sheet is now located with the rear edge on the sheet brake 6, while the front area floats on the air cushion T T which has been washed in previously. This cushion gradually escapes between the sheet 3a located on the sheet stack 10, so that contact only takes place when no more translatory movement is carried out.
