Definitions

  • the invention relates to a delivery device in the folder of a rotary printing press.
  • the folding copies that are produced in the folder of a rotary printing press are slowed down by complex and complex slowdown devices.
  • blown air nozzles are known, with the aid of which the folded copies are pressed against the airfoil surfaces in order to increase the friction and thus the braking.
  • US-PS 4,522,387 a paddle wheel device is known, in which a special arrangement of a plurality of paddle wheels mounted on a common shaft is realized. The rotational position of the individual vane wheels relative to one another on the common shaft differs from vane wheel to vane wheel. In addition, the length of the spiral slots is offset from one another.
  • the objects are braked only on one side of the slots, the opposite side of the slots remains unused.
  • the breakdown of kinetic energy due to friction is also very limited due to an air boundary layer surrounding the folded products.
  • EP-A-0 509 210 (state of the art according to Article 54 (3) EPC) is a delivery device with a paddle wheel, which consists of individual paddle blades, between which paddle wheel pockets are formed for receiving incoming fold copies, and the leading edge of a rear paddle blade - based on an incoming folded copy - a first profile, the trailing edge of a front airfoil - based on an incoming folded copy - has a second profile.
  • the bucket wheel boom points adjustable folding product guides depending on the format.
  • the bucket wheel boom described there comprises bucket pockets which comprise a funnel-shaped inlet area which narrows in the direction of the axis of rotation of the bucket wheel.
  • the funnel-shaped inlet area is delimited by a contoured edge of an airfoil.
  • the enormous advantage of this invention lies in the fact that the fold copies are braked even at higher speeds by simple means on the paddle wheel, without complex additional devices being required. Due to the shape of the respective leading and trailing edges of the individual blades, a considerably higher dispersion of kinetic energy, ie braking, can be achieved. It is also important that the folded product is forced by an angle of impact when Enter into the paddle wheel pocket so that a curve is formed along its length. The folded products are treated gently and are not braked abruptly, but gradually in the paddle wheel pocket. The profiling offers the advantage that a controlled deformation can be impressed on the folded products as they pass through the paddle wheel pockets. There is a gradual braking, which prevents a sudden impact of the folded products on the bottom of the shovel pockets.
  • a further embodiment of the invention provides that the profile of the airfoils has a striking section at their leading edge and the paddle wheel pocket formed from the leading edge and trailing edge is curved in its lower region in the direction of the impeller wheel hub.
  • the impact line is on one level with the exit of the folded products from a conveyor belt system. This allows the folding products to be braked for the first time immediately after they have entered.
  • the paddlewheel pockets are designed with multiple meandering shapes.
  • the advantage of this configuration is that the folded product can be additionally opened by alternating the leading and trailing edges of the airfoils.
  • bucket wheel pockets have an inlet area and that the bucket wheel pocket has a constriction due to a discontinuous contour on the trailing edge of an airfoil. As a result, the deceleration only takes place after the folded product has been completely taken up by the paddle wheel pocket.
  • an angle ⁇ 1 is formed between the folded products entering the paddle wheel pocket and the point of impact of the leading edge of the blades. This angle of attack ⁇ 1 ensures that the incoming folded product runs safely into the paddle wheel pocket.
  • an angle ⁇ 2 is provided between the end of the striking section and the folded product leaving the striking section.
  • an angle »2 between the front edge of the folded product and an output portion of the second concave recess is provided.
  • the advantage here is that a further braking of the folded product takes place during the passage of the second concave recess immediately before reaching the bottom of the paddle wheel pocket.
  • an embodiment of the invention is characterized in that the length of the paddle wheel pockets exceeds that of the folded products and the entire length of the folded product enters the paddle wheel pocket. This ensures that the delay line can be used as long as possible.
  • leading edge in the area of the impact and the trailing edge in the area of the retardation of the first concave recess and the second concave recess are formed from ink-repellent material.
  • an impeller 4 which consists of strongly curved blades 5.
  • the Blades 5 are delimited by leading edges 6 and trailing edges 7.
  • the leading edge 6 has a first profile 8, while the trailing edge 7 of an airfoil 5 is provided with a second profile 9.
  • each blade 5 is provided with profiles 8 and 9.
  • Another conceivable embodiment in the above sense would be to arrange alternating blades 5, in which only one of the edges is provided with a profile.
  • the arrangement shown in FIG. 1a is preferably to be used.
  • Each of the paddle wheel pockets 14 for an incoming folded copy 3 is determined by a trailing or rear airfoil 5 with a leading edge 6 with respect to an incoming folded copy and from a leading or front airfoil 5 with a trailing edge 7 in relation to the incoming folded copy 3.
  • the vane wheel pockets 14 formed by the vane blades 5 are more curved in the inner region in the direction of the vane wheel hub 16. This allows a controlled deformation of the folded copies 3, which one Degradation of the kinetic energy of the folded copies.
  • the paddle wheel hub 16 has a center 23.
  • the illustration of the paddle wheel hub 16 in the front view of FIG. 1b shows a possibility of fastening the paddle wheel 4 on a carrier shaft.
  • FIG. 2a and 2b details of the profiling of trailing edges 7 of the blades 5 are shown.
  • FIG. 2b shows a first concave recess 11 on the trailing edge 7 of an airfoil 5.
  • the trailing edge 7 has an inlet section 24 following a delay line 10 shown in FIG. 3. This is followed by an outlet section 20.
  • the paddle wheel pocket 14 is determined by the leading edge 6 and the trailing edge 7.
  • a concave recess 12 is shown in detail in FIG. 2a. This is also located on the trailing edge 7 of an airfoil 5, but further down in the airbag 14 (see FIG. 1a).
  • the concave recess 12 also has an inlet section 25 and an outlet section 21 in order to brake the folded copies 3.
  • Figure 3 shows an enlarged section of a paddle wheel with details of the edge profile.
  • Conveyor belts 1 running around conveyor belt rollers 2 introduce folded copies 3 into an inlet area 18.
  • the inlet area 18 is wedge-shaped.
  • the leading end of the folded copy 3 and the tangent of the impingement section 13 form an angle ⁇ 1.
  • This angle ⁇ 1 is preferably between 15 ° and 20 °.
  • the folded copy 3 passes through a first braking step along the impact path 13. After passing through the impingement section 13, the leading end of the folded copy 3 arrives at an angle ⁇ 2 Delay section 10, which is formed on the trailing edge 7 of the previous airfoil 5.
  • the angle ⁇ 2 is preferably in a range between 20 ° and 25 °, although other angles would also be conceivable.
  • the folder 3 is subject to a second braking step.
  • a controlled deformation is impressed on the folded copies, by means of which the kinetic energy of the folded copies 3 is additionally reduced.
  • the folded copy 3 is deformed in its entire length during its passage from the impact section 13 and the delay section 10 and caused to change the directions of movement.
  • the entire length of the fold copy 3 is available as a usable braking surface, not only the leading end of the fold copy 3.
  • all parts of the fold copy 3 are used for deformation and thus for reducing the kinetic energy. As a result, the mechanical stress on the folded copies 3 is evenly distributed and damage to the sensitive leading end of the folded copies 3 is prevented.
  • the leading end of the folded copy 3 After passage of the delay section 10 of the trailing edge 7, the leading end of the folded copy 3 reaches the inlet section 24 of the concave recess 11 in the trailing edge 7. After reaching the concave recess 11, the folded copy 3 has completely entered the paddle wheel pocket 14. Fluttering of the rear part of the folded copy 3 in the entry area of the paddle wheel pocket 14 is thereby avoided.
  • the leading end of the folded copy 3 When the leading end of the folded copy 3 runs in, it undergoes a third braking step and follows the delay through the trough-shaped recess in this embodiment and after passage of the outlet section 20 again the further curvature of the paddle-wheel pockets 14.
  • the angle between the imaginary extension of the inlet section 24 and the outlet section 20, denoted by »1, is preferably 55 ° , although it can also have a lower value.
  • the leading end of the folded copy 3 reaches another concave recess 12.
  • the leading end of the folded copy 3 is further delayed by this nose-shaped recess provided in the lower region of the paddle wheel pocket 14.
  • the angle »2 which is preferably 70 °, but can also assume other values.
  • the strongly curved region of the paddle wheel pocket 14 adjoining the concave recess 12 extends to the pocket base 15, on which the delayed fold copy 3 finally hits.
  • the third and fourth braking steps are used to specifically brake the pre-running end of the folded copy 3, which has already undergone two braking steps.
  • the leading end of the folded copy 3 has passed the concave recesses 11 and 12
  • the remaining part of the folded copy 3 is forced to move along the recesses 11 and 12 and thus further kinetic energy is reduced.
  • the trailing edge 7 provided with a profile 9 - consisting of the deceleration section 10 and the concave recesses 11 and 12 - as well as the leading edge 6 provided with a profile 8 - consisting of the impinging section 13 and strong curvature - results in a deliberate deceleration of the individual Folded copies 3 reached.
  • the length of the paddle wheel pockets 14 may exceed the length of the fold copies 3 to be braked. This means that a long braking distance is available.
  • the length of the paddle wheel pocket 14 should be designed such that the folding specimen 3, which is braked in stages, reaches the pocket base 15 and there is further braking. Then the fold copy 3 is already delayed to such an extent that damage to the fold copy edges is excluded. Reaching the pocket base 15 ensures that the folded copies 3 removed from a stripper can be interpreted as a uniformly scaled stream.
  • the above-described slowdown concept for rebate copies by profiling the airfoil edges therefore consists of a large-scale braking by friction as the first slowdown steps.
  • 3 folds are impressed on the fold copies, which additionally reduce the kinetic energy of the fold copies moving at high speed.
  • additionally impressed deformations absorb kinetic energy on the fold copies and intensify the slowing down due to friction, since the deformed areas of the fold copies are pressed against the leading edge 6 or the trailing edge 7 with greater normal force.
  • folded copies reach the bottom 15 of the pockets.
  • the leading edge 6 in the area of the impact section 13 and the trailing edge 7 in the area of the decelerating section 10 of the first and the second concave recesses 11 and 12 can be formed from ink-repellent material.
  • 4a and 4b show design options for airfoil edge profiles.
  • FIG. 4a shows a paddle wheel pocket 14 which is curved in a meandering manner in its pocket region which is closer to the paddle wheel hub 16.
  • the leading edge 6 and the trailing edge 7 of the airfoils 5, following the inlet area 18, have a multi-curved profile, which can consist of convex projections 27 and these corresponding concave troughs 28.
  • FIG. 4b Another pocket configuration is shown in Figure 4b.
  • the inlet area 26 is kept much longer and wider than in the exemplary embodiment shown in FIG. 4a.
  • the trailing edge 7 is provided with an unsteady contour 19, with the aid of which the folded copies 3 are braked before they strike the pocket base 15.
  • the trailing edge 7 of an airfoil 5 can be provided with a large number of such contours 19.
