Definitions

  • 2-wheel rebate are folding capacities of up to 160 pages and high running speeds, because the collecting sheets are not guided around a 1/2 large cylinder, but around a 3/2 large cylinder, which only rotates at 2/3 the speed of the 2/2 plate cylinder of the newspaper press rotates and exerts only 1/3 of the centrifugal force of the 2: 1 folder.
  • the main disadvantage of the 3: 2-wheel folder is the complicated design with the hollow collecting cylinder rotating eccentrically around the folder holder. Switching from double to collective production by decommissioning one of the two folding knives within the hollow cylinder is difficult to access and complex. Even more serious is the fact that the 2/2 cutting knife cylinder cuts against the hollow collecting cylinder, which is not very stable for design reasons. When cutting thick-sided newspapers, considerable cutting forces occur. The alternating bending caused by centrifugal force and cutting force has in practice led to material fatigue on the hollow collecting cylinder and dangerous fatigue fractures.
  • Another 3: 2-wheel fold according to US-PS 31 44 249 works within the 3/2-cylinder with three rotating folding knives. Switching from double to collective production is done conveniently from the outside by letting the sun gear move along in batches, which suppresses every second hypocycloid tip. When the sun gear is at a standstill, however, all three knives swing to hypocycloid tips simultaneously. Therefore, a 3/2-sized, hollow collecting cylinder must rotate as a relatively weak casing and eccentrically offset to the axis of the folding knife carrier, so that the upper hypocycloid tips do not come out of the casing of the collecting cylinder let it come out. This construction is therefore also characterized by high cutting forces on the hollow collecting cylinder and endangered by fatigue fractures.
  • US Pat. No. 3,348,837 works without an eccentrically offset rotating 3/2 collecting cylinder.
  • the 3/2-cylinder is designed as a solid cylinder and three rotating folding knives are fixed in the collecting cylinder, which is also the folding knife holder.
  • the high cutting forces between the 2/2 cutting cylinder and the 3/2 collecting cylinder are thus absorbed by solid cylinders.
  • the object of the invention is a wheel folder for double and collective production of strong products at high speeds speed, ie with a cylinder ratio of the folding knife cylinder to the cutting cylinder greater than 2: 1.
  • the high cutting forces of massive cylinders should be able to be absorbed.
  • an almost uniform paper draw should be aimed for.
  • the wheel folder according to the invention consists of a cutting knife cylinder which carries three sets of cutting knives on the circumference and three point sets, so that it can also serve as a 3/2 collecting cylinder.
  • the counter-cutting cylinder also has a 3/2 circumference, carries three counter-cutting bars, three sets of punctures and three rotating folding knives, which always describe normal hypocycloids with three tips.
  • the tip of the lower folding knife stop pushes the products into correspondingly arranged folding rollers.
  • each cutting knife does not work in a skipping manner, but always works with the same counter-cutting bar.
  • Means are also available to selectively control the punctures of the 3/2 cutting knife collecting cylinder and the 3/2 folding knife cylinder in such a way that double or collective production occurs.
  • hollow cylinders rotating in an eccentrically offset manner can be dispensed with.
  • the incoming strands can be used in double and bulk production with almost even, i.e. H. not very pulsating paper pull are pulled from the folding cylinder group.
  • Another advantage is that superimposition and other gears are eliminated, i. H. the rotating folding knives can describe hypocycloids produced by robust, simple gears. After all, the folding cylinder group has no more than two cylinders.
  • the 3: 3 folder according to the invention ie three-field folding knife cylinder and three-field cutting cylinder, is characterized by space-saving, simple and robust construction.
  • the collecting layer runs around the cutting cylinder and, similarly to 2: 1 folders, is needled onto the incoming strand from above.
  • the gathering layer does not increase the radius of the 3/2-fold knife cylinder, so that the paper pull is not influenced by the gathering layer.
  • double and bulk production there are almost the same draw ratios because 3/2 folding knife and 3/2 cutting cylinders have curvatures of the same size; it remains the same for the incoming strand, oo z.
  • the cutting / collecting cylinder is arranged in such a low position on the folding knife cylinder that the hypocycloid tip emerging at the top right does not touch the incoming strand.
  • the folder knives should emerge several times - three times - from the folder cylinder surface, so that a simple, unmodified folder movement can be used.
  • Fig. 1 are over former 1; 2 paper webs 3 longitudinally folded and the strands 4; 5 passed by means of pull rollers 6 and union rollers 7 onto the 3/2-fold knife cylinder 8.
  • Three sets of punctures 9.1; 9.2; 9.3 needles the combined strand 10 alternately on the 3/2-folding-blade cylinder 8 and 11 result in double production, the cut sheet directly into the folding rollers 120 0 staggered folding blade 12; 13; 14 are rotatably supported in the folding knife cylinder 8 and, by means of an internal gear ratio 3: 1 against a stationary sun gear, describe three-pointed hypocycloids known per se compared to a stationary system. Folding knife 12 just pushes a newspaper into folding rollers 11.
  • a 3/2 cutting knife cylinder 15 carries three cutting knives 16 offset by 120 °, as well as three sets of controllable punctures 17.1; 17.2; 17.3.
  • the punctures 17.1 to 17.3 are always drawn in in the cutting line and the punctures 9.1 to 9.3 are always extended, so that after the cut all sheets are guided around the folding blade cylinder 8 and immediately pushed into the folding rollers 11.
  • the punctures 9.1 to 9.3, 17.1 to 17.3 are alternately controlled in such a way that odd-numbered (A) arcs are guided around the cutting-collecting cylinder 15 and three steps later together with an even-numbered (B) arch through punctures 9.1 to 9.3 of the folding blade cylinder 8 are needled and guided to the folding rollers 11, into which the rotating folding blades 12 to 14 protrude.
  • the two-cylinder folder is driven by a longitudinal shaft 20, standing shaft 21, transverse shaft 22.
  • the drive for the pulling rollers 6, 7 and the hopper inlet roller 23 is also derived from the standing shaft 21.
  • Fig. 2.1 to 2.6 explain the collective production when starting up.
  • First sheet 101 hangs in punctures 17.1 of cutting collecting cylinder 15, puncture 9.2 takes sheet 102, while puncture 17.2 in cutting collecting cylinder 15 withdraws.
  • Second sheet 102 (FIG. 2.2) is guided from point 9.2 to folding knife cylinder 8 for folding, while point 9.3 is withdrawn.
  • point 17.3 takes sheet 103 and guides it - Fig. 2.3 - around the cutting collecting cylinder 15.
  • Point 17.1 has brought sheet 101 again to the cutting line - here it is taken from point 9.1, which has already entered incoming sheet 104.
  • the cover plates 37; 38 rotate counter to the direction of rotation of the associated cylinders 8, 15, but only at 3/4 of the cylinder speed.
  • cover plate 37 closes curve 34 and allows punctures 9.2 of the folding knife cylinder to extend.
  • the cam 36 of the fixed control cam 33 remains open because the cover disk 38 is at a 90 ° distance from the cam 36.
  • collection point 17.2 withdraws to point 9.2 for the purpose of transferring the bow.
  • Puncture 9.2 guides the following sheet 102 around the folding knife cylinder 8. The position corresponds to phases 2.1 and 2.3 and 2.5.
  • Fig. 3.2 (or phase series of Fig. 2.2 and Fig. 2.4 and Fig.
  • the cover plate 37 is 30 ° in front of curve 35, leaves the curve 35 active and the puncture 9.2 withdrawn.
  • the cover disk mechanism works in such a way that with every second passing puncture 9.1 to 9.3, 17.1 to 17.3, alternating cam valleys 34 for folding knife cylinder 8 and cam 36 for cutting collecting cylinder 15 are covered, while the cam 35 offset by 120 ° for each passing puncture 9.1, 9.2 and 9.3 remains active, ie is not covered.
  • Both circumferential cover disks 37; 38 have 34; 35; 36 two circular arc pieces offset by 180 °. They are over gears 40; 41 and, intermediate wheels 42; 43 driven in rotation ratio 3: 4 by drive wheels 44; 45.
  • cam 36 At the cutting-collecting cylinder 1'5, cam 36 always remains active, so that punctures 17.1 to 17.3, always drawn through the interface, cannot pass a collecting arc around the cutting-collecting cylinder 15.
  • the cylinder ratio can also be selected from 5: 5 or 7: 7 instead of 3: 3 to reduce the centrifugal force values. While the cutting-collecting cylinder 15 must always have an odd number of punctures or fields, the folding knife can cylinders 8 also have an even number. This means that 4: 3 or 6: 3 or 6: 5 ratios are also possible. Cutting knives and counter-cutting bars could also be interchanged on the cylinders 8, 15, but this leads to malfunctions during the folding process due to the above cutting knives and is not recommended.
  • the second pass of the collection sheet is chnipseln through the interface, an S avoided in that the diameter of the cutting-collecting cylinder is kept slightly smaller than the diameter 15 of the folding blade cylinder. 8
  • the layers revolving around the cutting-collecting cylinder are cut somewhat shorter than the layers guided around the folding knife cylinder 8.
  • Another shortening effect for the collecting layers occurs in that they run on the somewhat larger folding knife cylinder not on the cylinder surface, but on a radius increased by the thickness of the sheet package, so that the angle taken is less than 120 °.
