Definitions

  • the invention relates to a sheet brake according to the preamble of claim 1.
  • printed sheets are fed through by a feeder Printing units and then on a chain conveyor system to a so-called delivery transported and stored there printed on a stack.
  • a feeder Printing unit In sheet-fed rotary printing machines, printed sheets are fed through by a feeder Printing units and then on a chain conveyor system to a so-called delivery transported and stored there printed on a stack.
  • the printed printed sheet is from a floating position lower onto the stack surface.
  • DE-OS 2 720 674 describes a sheet delivery device for a rotary printing press known.
  • this sheet delivery device is close to that Trailing edge of a stack on a boom of the rotary printing press Brake device provided for incoming printed sheets.
  • This consists of one Box with several slits on the top. This box comes with blowing air acted upon by a first part directed against the sheet running direction Slits escape.
  • the press sheet can then be guided against stops in the area of the boom stack. Is to however, the curved path or the chain conveyor in the area of the delivery above the stack inclined downwards in the direction of sheet travel. This is very disadvantageous because the space for any intended sampling is severely restricted.
  • the Box or the braking device with a lifting movement transverse to the direction of sheet travel the printing sheet is loaded. As a result, the printed sheet to be deposited is sent to the Gripper systems out of the sheet running direction, up to about the height of the upper edge pulled down by alignment stops at the rear edge of the stack and can be there be filed.
  • a disadvantage of the device mentioned is that, especially in the case of large-format, i.e. heavy, printed sheets, a targeted braking is not possible. For this reason the sheet delivery device also sees the additional powered alignment stops on the rear edge of the boom stack, which ensure that the to be put down Printed sheets are just pushed against the leading edge stops. Due to the The pressure sheet from the grippers has to blow up to the braking device be held at the last moment to get it sufficiently down against the Leading edge stops. In addition, the slope is also downward Sheet guide The braking device described corresponds to one otherwise so-called bow catcher. Bow arresters are generally used to to keep a sheet in its path and to force it in a certain direction where an intended braking effect is only the smoothing of the sheet in Direction of sheet travel can serve, but less because of the priority management effect can serve the braking.
  • a sheet delivery device is known from DE-GM 80 03 052.
  • she shows the combination of a suction roll and a blow-suction device in the form of a Sheet brake, which is in the sheet running direction in front of the trailing edge of a sheet stack Bow delivery arranged and oscillating between a catch position and a Storage position can be raised and lowered.
  • the blowing and suction device Suction roller rigidly connected to each other so that the oscillating lifting movement run together.
  • the blow-suction device is intended to capture the printed sheets and the Feed the suction roller.
  • the device has various disadvantages in the treatment of printed sheet to be filed.
  • the print sheets are guided on the wheels the suction roller only selectively, so that a smooth, as flat as possible delivery especially large-format printing sheets is not always possible.
  • the blow-suction device a stream of air is blown under the incoming printed sheet, the unrest in brings the sheet run and a safe capture of the printed sheets also particularly large format substrates hindered. This measure also hampers the flat delivery of the printed sheets.
  • CH 611 579 A5 is used to flatten paper sheets Additional device known on a paper sheet processing machine. She assigns one Support that should touch the sheet of paper on three cylindrical surfaces. Thereof provide two surfaces with a larger radius and as a wall on suction chambers educated. The third surface has a smaller radius and is on the back Suction chamber attached. Both between the first two and the latter two Guide surfaces are arranged in suction openings in the suction chambers. The curvature of the The surface is oriented towards the paper sheet to be guided.
  • Additional aids are for the display of, in particular, large-format printed sheets so-called acceptance gripper known. These take over the supplied printed sheet from the gripper systems of the chain conveyor and guide it while slowing down the Speed against the leading edge stops. They only act selectively on the Printed sheets, which can lead to distortion and uneven braking. In addition, the printed sheets become strong at high speeds Delay in an unstable orientation plane exposed.
  • the object of the invention is therefore a bow brake according to the preamble of To improve claim 1 so that the printed sheet to be interpreted with a larger Accuracy and safe can be stored, with the addition of the flat position of the arch should be so positively influenced when laying out that from the transport movement of the Arise differences in position are avoided.
  • the printed sheet is advantageously guided, stretched and lowered in two stages on its rear edge. It can also be held at the front edge by grippers and at the rear edge by the sheet brake, without accepting disadvantages.
  • the bow brake in a third version thanks to its particularly suitable shape keeps the printed sheet taut and spread sideways, it can safely and in stretched position with an optimally adjustable speed reduction on the Boom stacks are stored.
  • the printed sheet runs in this way as it is approximate is placed under a forced tour, almost a spot landing.

  • the arrangement of the rigid suction bar 20 on the suction chamber 16 represents one of the essential features of the sheet brake 5. This is its very simple structure justified.
  • FIG. 7 The assignment of the suction openings 22 to the groove 21 is shown in FIG. 7 in a sectional view presented in a little more detail. Above all, it is shown here that the top of the Squeegee 20 is smooth and has transition contours that are clean Allow bow guidance. It is essential that the suction openings 22 have a diameter have that is smaller than the width of the groove 21. This ensures that the weak Obtain the radius of curvature of the two trailing edges of the groove 21 over their entire length remains.
  • the top view of the suction bar 20 shows how the Suction openings 22 are arranged in the groove 21.
  • the selected and displayed Assignment of the suction openings 22 to the groove 21, as already mentioned, is due to the fact that that with a further extension of the suction opening 22 to the edge of the groove 21st sharp-edged areas at the edge of the groove 21 can arise, so that it too Damage to the printing sheet 1 could occur. Therefore, in the field of arrows shown a distance between the edge of the suction openings 22 and Leading edge of the groove 21 is provided.

  • the purpose of arranging a separate squeegee 20 is as follows: After a long time Operating time, it is possible, in the event of inevitable wear, the suction bar 20 on the sheet brake 5 easily by replacing it with a new suction bar 20 replace. Therefore, the entire sheet brake 5 does not have to be revised or even replaced become.
  • the function of the sheet brake 5 is as follows:
  • the printed sheet 1 is on the chain conveyor system 2 from the printing press Boom stack 3 out. After the gripper systems have passed, the Printed sheet 1 detected and guided by means of the sheet catching device 25. Running at the same time the printed sheet 1 past the sheet brake 5, which is synchronous to Arc movement is raised by the drive 15 via the crank 9 and the Printed sheet 1 captured by suction against the squeegee 20. Because of the special selected distribution of the suction openings 22 over the entire width of the sheet brake 5 sets in the groove 21 at the same negative pressure everywhere. This leads to the fact that the Sheet 1 is sucked a little into this groove (see Figure 7). With that forms A slight, groove-shaped deformation over the entire width of the printing sheet 1.
  • the sheet brake 5 shown is particularly advantageous in connection with so-called re-grippers 23. These are in the area of the front edge 24 of the Delivery stack 3 arranged and take over the printed sheet 1 after which it from Chain conveyor system 2 has been released.
  • the take-off gripper 23 perform an im Bow cycle and back and forth movement in the sheet running direction R. Here take over the printed sheet 1 from the chain conveyor system 2 and carry it with you decreasing speed on the surface of the boom stack 3 and to it Front edge 24.

  • At the Interaction with grippers 23 shows the special advantage of the groove 21 in FIG Suction bar 20.
  • the take-off gripper 23 can only act selectively on the printed sheets it comes especially with lighter substrates that a sheet 1 at Pulling over the sheet brake 5 is distorted. The effect arises that the Printing sheet 1 slides together at its rear edge transversely to the sheet running direction R and Waves or folds in the sheet running direction R forms. This disadvantage is caused by the stretched guidance avoided by means of the groove 21. This is also the case with light paper Pick-up gripper 23 with no problems in delivery and at all speeds Can be used in conjunction with the sheet brake 5.
  • a arriving at the chain conveyor 2 sheet 1 is from the Sheet catching device 25 detected and tightened in the sheet path.
  • the sheet brake 5 has reached its highest point and detects the printed sheet 1. It is sucked in and during the forward movement in one downward sinusoidal movement. This is the fastest downward movement only reached when the trailing edge of the printed sheet 1 reaches the sheet catching device 25 overwhelmed. So it is ensured that the sheet brake 5 at its leading down Do not move the trailing edge of the printed sheet 1 onto the sheet catching device 25 touches down and the printed sheet 1 is possibly lifted off the sheet brake 5.
  • the printed sheet 1 is passed to the take-off gripper 23, which takes it on the leading edge stops on the boom stack 3 leads. During this the Printing sheet 1 is lowered further and further from the sheet brake 5 onto the stacking surface and kept stretched laterally under the action of suction into the groove 21.
  • the chamber 18 in FIG. 6 can also be operated with negative pressure be provided and an additional braking surface via suction openings on their top produce. This auxiliary measure is used in the event that heavy materials are to be processed.
  • FIG. 9 A further alternative solution resulting from this in a simplified form is shown in FIG. 9 shown.
