Definitions

  • the invention relates to a sheet delivery for printing machines according to the preamble of claim 1.
  • Such a sheet delivery has become known from DE-PS 20 47 808.
  • This has rear sheet stops, which are swiveled transversely to a sheet transport direction when an auxiliary storage table is inserted. By swiveling the sheet stops, they are disabled.
  • additionally arranged sheet stops are lowered onto the auxiliary deposit table.
  • These additional bow stops are connected to the swing-away bow stops by means of an auxiliary linkage.
  • the disadvantage is the arrangement of additional sheet stops and the complex construction for their actuation.
  • sheets that are placed on the auxiliary storage table during the insertion of the auxiliary storage table can be clamped between the auxiliary storage table by lowering the additionally provided sheet stops. This would destroy any jammed sheets when the auxiliary storage table was pulled out, which would lead to incorrect stack formation and thus to premature stack change or even machine stop.
  • the invention has for its object to provide a simple sheet stop for the sheet trailing edge on cantilevers on sheet-processing machines, which causes an alignment of the main sheet stack in the sheet transport direction and in particular when inserting an intermediate stacking device in the area of the sheets to be deposited prevents the sheet or sheets from an upper Position of the main sheet stack as well as the sheets placed on the intermediate stacking device can be shifted from a predetermined, aligned position by inserting the intermediate stacking device.
  • the advantages of the sheet stops according to the invention are in particular that they avoid the disadvantages of the prior art and, moreover, continue to align the sheets of the main stack during the insertion of an intermediate stacking device.
  • the simple construction is inexpensive to manufacture, is not susceptible to faults and is easy to use, which reduces maintenance costs and machine downtimes.
  • a sheet delivery 1 for a printing press has a chain wheel 2 and a revolving, endless chain 3, on which sheet gripper devices 4 are arranged.
  • the sheets 6 are printed by a printing machine, not shown, and transported by the sheet grippers 4 via a main sheet stack 7, via which they open their gripper closure at a predetermined point and drop the sheet 6.
  • the trailing edge of the sheet is held by a braking device 8 (e.g. suction roller), which decelerates the speed of the sheet.
  • the braking device 8 is mounted in a crossbar (not shown) which can be displaced horizontally between the frame walls 9, 11 of the sheet boom 1. The traverse can be adjusted to different arch formats due to its horizontal displaceability.
  • the strip 13 has a carriage 12 which is fixedly connected to the strip 13.
  • the carriage 12 is provided on its side facing the frame wall 9; 11 with two rotatably mounted rollers 41, 42, which are guided horizontally in a guide 43 fixed to the frame wall.
  • a first roll 41 is in each case in FIG Contact with a cam 46 arranged eccentrically to the braking device 8.
  • a compression spring 44 is supported on one side in each case on the frame wall 9, 11 and on the other side on the slide 12. A horizontal deflection of the slide 12 forced by the cam 46 takes place against the restoring force of the compression spring 44.
  • the sheet stops 18, 19 are so long that they cover an upper area of the main sheet stack 7 and thus also form a stop for the sheets of the upper area.
  • both the sheets 6 on the main sheet stack 7 and the sheets 6 on an intermediate stack 25 on the intermediate stacking device 21 are aligned by means of the oscillating sheet stops 18, 19.
  • the sheet stops 18, 19 act during the separation of the lower main sheet stack 7 from an upper intermediate stack 25 on the trailing edges of both stacks 7, 25 until the intermediate stacking device 21 with its front edge Has reached bow stops. At this moment, the upper intermediate stack 25 is separated from the lower main sheet stack 7. Alignment of the lower main sheet stack 7 is no longer necessary, therefore the sheet stops 18, 19 become transversely to the sheet transport direction or transversely to the direction of insertion of the intermediate stacking device 21 around the bolt when the intermediate stacking device 21 is inserted, preferably when the intermediate stacking device 21 comes into contact with the sheet stops 16; 17 pivoted upwards until they come to rest on the surface of the intermediate stacking device 21. An oscillating movement of the sheet stops 18, 19 then takes place in contact with the surface of the intermediate stacking device 21.
  • the pivoting movement of the sheet stops 16, 17 is triggered by a device on the front part of the intermediate stacking device 21.
  • the intermediate stacking device 21 has at a distance b (b ⁇ a) two bevels 23, 24, the extensions 26, 27 of which intersect at an acute angle ⁇ (for example 90 °), the tip 28 formed at the angle ⁇ points in the direction of insertion of the intermediate stacking device 21, that is, counter to the sheet transport direction.
  • a force acting downward on the arch stops 18, 19 is applied solely by the gravity of the arch stops 18, 19.
  • the sheet stops 18, 19 hang in the basic position, ie when a main stacking plate 31 is pivoted so far that it no longer has any contact with the sheet stops 18, 19, always inclined at a small angle ⁇ (approx. 15 °) to the vertical 29.30.
  • This arrangement ensures that the main stacking plate 31st when starting up in the empty state, for example, by contacting the sheet stops 18, 19, these are pivoted so that the sheet stops 18, 19 rest on the main stacking plate 31 only under their own weight.
  • the intermediate stacking device 21 is of simple construction as a stacking plate and has on its side edges 32, 33 in each case a number of rotatably mounted rollers 34, 36, by means of which it is guided horizontally in rails 37, 38 in an easily displaceable manner.
  • the rails 37, 38 are fastened to the frame walls 9, 11.
  • the front bow stop 39 is provided below the sprocket 2 and is pivotally attached to the frame walls 9, 11.
