Definitions

  • the invention relates to a bucket wheel boom for folded copies according to the preamble of claim 1.
  • a generic bucket wheel boom is known from the "Atlas of Newspaper and Illustration Printing" by A. Braun, Frankfurt am Main, 1960, page 70.
  • the folding copies coming from a folding jaw cylinder fall vertically into the gaps formed by curved blades of a blade wheel consisting of a plurality of axially spaced apart blade wheel disks.
  • Resilient brake tongues are arranged in the spaces between the impeller disks, which partially narrow the gap. Due to the increased friction between the brake tongue and the inner contour of a blade, the folded copies in this narrowed area are braked to the lower peripheral speed of the blade wheel compared to the jaw cylinder. This braking happens quite abruptly, so that it can lead to compression or wave formation on the front edge of the folded copy.
  • DE-B-1 224 135 shows a paddle wheel with leaf-spring-shaped blades which can be pressed down by means of curved arches or rollers, with which the width of the pockets formed by the blades can be adjusted. But here too, depending on the set Bucket width the braking is done abruptly more or less deep in the pockets.
  • the invention has for its object to provide a bucket wheel boom with which a compression-free braking of the folded copies is made possible.
  • a folder 1 delivered from the folding jaw cylinder, not shown, is transported via two belt guides 2, 3 with adjustable belt guide rollers 4, 5 to the paddle wheel boom 6 arranged underneath.
  • the bucket wheel boom 6 carries on a common axis 7 a plurality of axially spaced bucket wheel disks 8, each of which has an equal number of evenly distributed, curved blades 9, 10.
  • An inside 91 of a blade 9 and an outside 102 of a blade 10 following in the direction of rotation delimit a gap 11 which, due to the curvature of the blades 9, 10 and their arrangement on the blade wheel disks 8, narrows continuously from the outside inwards.
  • brake tongues 12 are arranged on an angled support arm 13. The brake tongues 12 can be moved together with the support arm 13 along a straight line labeled X.
  • the support arm 13 is suspended with its rear end by means of a plate 14 fastened to it on two leaf springs 15, 16 acting as a leaf spring parallelogram, which in turn are fastened with their other end to a clamping body 18 arranged on a rod 17.
  • the linkage 17 is firmly mounted in the side walls of the folder, not shown.
  • a support plate 19 is also fastened to the clamping body 18 perpendicular to the direction of displacement X of the support arm 13.
  • An electric servomotor 20 and a rotary potentiometer 21 are flanged to this on the side facing away from the brake tongue 12.
  • a pinion 23 is arranged on a drive shaft 22 of the servomotor which penetrates the support plate 19 and which meshes with a gear wheel 25 which is arranged on a shaft 24 of the rotary potentiometer 21 which also penetrates the support plate 19.
  • a sleeve 26 is also slidably arranged, which is connected non-rotatably to that via a feather key 27.
  • the sleeve 26 has an external thread 28 which engages with an internal thread 29 of a bush 30 which is fastened to a plate 31 which is fixedly connected to the support plate 19.
  • the sleeve 26 carries on its end facing away from the servomotor 20 a pressure bolt 32 with a hemispherical end face.
  • the end face of the pressure pin 32 bears against an angled surface 33 of a pressure piece 34 with a T-shaped cross section.
  • a base plate 35 of the pressure piece 34 arranged parallel to the direction of displacement has two elongated holes 36, 37 running in the direction of displacement. In the area of these elongated holes 36, 37, two screws 38, 39 screwed into the plate 14 clamp the pressure piece 34 relative to the plate 14.
  • the pressure piece 34 is clamped on the plate 14 in such a way that the leaf springs 15, 16 still provide for a contact of the surface 33 with the pressure bolt 32 even with a completely retracted brake tongue.
  • the basic setting of the support arm 13 relative to the plate 14 can also be changed by means of an elongated hole 40 arranged at the rear end of the support arm in the direction of displacement and penetrating clamping screws 41, 42 connected to the plate
  • the displacement of the support arm 13 and thus the brake tongue 12 is caused by rotation of the servomotor 20.
  • a rotation of the drive shaft 22 of the servomotor is transmitted from the key 27 to the sleeve 26. Since the external thread 28 of the sleeve 26 is in engagement with the internal thread 29 of the non-rotatably arranged bush 30, the rotational movement is converted into an axial displacement of the sleeve 26.
  • the pressure pin 32 presses against the surface 33 of the pressure piece 34.
  • the brake tongue 12 is moved in the direction of a narrowing of the gap 11.
  • the actuating motor 20 is controlled by an electronic control device 43.
  • a base value 44 which is dependent on the thickness of the folded copy 1 and a value 45 which is dependent on the speed of the machine can be fed as input signals to this control device 43, from which a target value for the position of the brake tongue 12 is calculated together.
  • This target value is compared with an actual value 46 supplied as a further input signal by the rotary potentiometer 21 to the control device 43. If the comparison exceeds or falls below the target value in this comparison, this leads to a corresponding output signal 47 of the control device 43, by means of which the servomotor 20 is set into a rotary movement correcting the control deviation.
  • two brake tongues 12 are arranged on different support arms 13 and each can be moved by a separate servomotor 20.
  • the servomotors 20 are each actuated by a control device 43.
  • the brake tongues 12 brake a specimen falling into the paddle wheel independently of one another on one side of the same. If an imbalance of the copies is found in the shingled stream on the delivery belt adjoining the folder, a change in the base value 44 on that of the control devices 43, which controls the position of the brake tongue 12 on the side of the leading leading edge, can result in a greater braking than on that other side. In this way, specimens falling obliquely into the paddle wheel can be aligned at their front edge by braking to different degrees.
  • control device 43 can be supplied as an additional input value with an emergency stop signal 48 triggered by a web tension measuring device (not shown) in the event of a sudden drop in the web tension.
  • a web tension measuring device not shown
  • the brake tongue 12 is immediately retracted regardless of the preset setpoint or calculated as a function of the machine speed.
  • the remaining copies still in the folder, which are made from the web section located in front of the tear point, can fall freely into the paddle wheel. This prevents a paper jam that otherwise occurs frequently in the inlet area of the bucket wheel boom in the event of a sudden machine stop.
  • FIG. 2 The gentle braking of the folded copies 1 caused by the brake tongue 12 according to the invention is shown in FIG. 2.
  • a blade 9 in different positions is shown in this with 9a to 9h.
  • the uniform distances between the positions shown mean, at a constant angular velocity of the paddle wheel disks 8, a constant peripheral velocity of any blade point.
  • the points of intersection from the inside and the outside contour are designated with capital letters from A to H in the movement phases of the blade 9 which are spaced apart from one another at the same time.
  • the fold copy 1 is continuously moved outwards through the outer contour of the brake tongue 12 between points A and H.
  • the distance that the leading edge of the folded copy travels at the same time intervals is continuously becoming smaller.
  • the paths between two adjacent points remain relatively constant; the folded copy 1 is already slowed down to a low residual speed and runs with its front edge against an ejection tongue 49 which is firmly in place at least one axial space between two paddle wheel disks 8 is arranged. From there, the fold copy 1 falls onto a conveyor belt (not shown) arranged underneath and forms a shingled stream there with the preceding and the following fold copies.
  • the brake tongue 12 can be adjusted both to the thickness of the item and to the dynamic conditions which change as a function of the machine speed. In the entire operating area and across the entire product range of the folder, a compression-free braking of the folder can be achieved.
  • bucket wheel booms for any web width can be put together from a basic module.
