Definitions

  • the invention relates to a device for trimming flat products, in particular multi-sheet printed products, such as newspapers, magazines, brochures and the like, on at least one of two mutually opposite edges, according to the preamble of claim 1.
  • a device is from EP-A -0 367 715 (or the corresponding US-A-5,113,731) known.
  • the invention has for its object to develop a device of this type in such a way that it can be adapted to printed products of different widths with little effort.
  • the subdivision of the cellular wheel according to the invention into two cell wheel halves which are axially adjustable relative to one another makes it unnecessary to replace the knives arranged on the spokes and rotating with the cellular wheel or to adjust them individually if the format of the printed products to be trimmed changes.
  • the assignment of the fixed counter knife to the rotating knives is retained during the axial relative adjustment of the two cell wheel halves, so that the counter knife do not have to be reset individually. This applies regardless of whether only one fixed counter knife or several of them are assigned to one or both cell wheel halves.
  • the device shown has the task of trimming multi-leaf, folded and stapled printed products P on their edge facing away from the fold, the so-called flower, and on two side edges running at right angles to the fold and the flower.
  • a first cellular wheel 2 is rotatably mounted about a vertical axis 3.
  • a second cellular wheel 4 is rotatably mounted about a horizontal axis 5.
  • the printed products P are fed from a feed conveyor 6 to the first cell wheel 2, where they are individually trimmed on their flower (so-called front trimming), then thrown individually from the first cell wheel 2 into the second cell wheel 4, where they are trimmed at their two side edges (so-called head / Foot cut) and finally conveyed individually by a conveyor 7.
  • the two cellular wheels 2 and 4 and the two conveyors 6 and 7 are driven continuously together by a motor 8 via a gear 9.
  • a shaft 10 extends vertically upward from the transmission 9, which engages with a drive pinion 11 arranged on it in a toothed ring 12 on the outer circumference of the first cellular wheel 2.
  • a horizontal shaft 13 extends from the transmission 9 to a toothed belt drive 14 which drives a lower horizontal shaft 15; on this two elongated drive pinions 16 are arranged, each meshing with a ring gear 17 on the outer circumference of the second cellular wheel 4. From these sprockets 17, the two conveyors 6 and 7 are driven via a toothed belt drive 18 and 19, respectively.
  • the first cellular wheel 2 which rotates in the direction of arrow 20 in FIGS. 1, 2 and 3, has a handle 21 which is axially immovably mounted on a bearing body 22 and is connected to a cylindrical casing 24 by thirty spokes 23. Thirty identical cells 25 which are open at the top and at the bottom are thereby formed.
  • the number of spokes 23 and cells 25 is not critical; it can be determined on a case-by-case basis as needed.
  • Each of the cells 25 is intended to receive a printed product with the flower lying horizontally above and to clamp it to one of the adjacent spokes 23 with a pressing device, which can be of a known type, in such a way that the printed product P can be trimmed on its flower.
  • a horizontal knife 26 is attached to the upper edge of each of the spokes 23 so that it rotates with the first cellular wheel 2.
  • the knives 26 are inclined backwards according to FIG. 3; each of them encloses an angle of approximately 20 ° with a radius starting from axis 3.
  • the bearing body 22 of the first cellular wheel 2 carries two knife bearings 27, on each of which a knife bar 28 is mounted, which carries a counter knife 29 that is stationary during operation. Only one of the two counter knives 29 assumes a working position in which it interacts with the rotating knives 26. If the counter knife 29 used first has become blunt, then the second counter knife 29 is pivoted into its working position by pivoting its knife bar 28, and the counter knife which has become blunt is pivoted together with its knife bar into a rest position.
  • the second cell wheel 4 which rotates in the direction of arrow 30 in FIG. 1, is composed of two cell wheel halves 4 'and 4' '.
  • Each cellular wheel half 4 ', 4' ' has a handle 31 which is mounted on a bearing body 32 and is connected by thirty spokes 33 to a cylindrical jacket 34 and via this to one of the mentioned gear rings 17.
  • the two cell wheel halves together form thirty cells 35, each of which extends between two spokes 33 arranged parallel to one another at an axial distance.
  • the number of cells 35 is not critical; it preferably, but not necessarily, corresponds to the number of cells 25 in the first cell wheel 2.
  • a knife 36 is attached to each spoke 33 and is inclined backwards at an angle of, for example, 20 ° to the radial direction.
  • Each of the two hubs 31 carries two knife bearings 37, on each of which a knife bar 38 with a counter knife 39 can be pivoted and is adjustable in a direction parallel to the axis of rotation 5.
  • Each of the two halves 4 'and 4' 'of the second cellular wheel 4 are thus assigned two counter knives 39, of which only one is in its working position, in which it interacts with the rotating knives 36 on the associated cellular wheel half, while the other counter knife in Reserve remains. 6 has a gable-shaped cutting edge.
  • the entire arrangement of the second cellular wheel 4 with its two halves 4 ′ and 4 ′′ and the associated counter knives 39 is symmetrical with respect to a plane of symmetry 40 normal to the axis of rotation 5. This applies to every operating setting of the second cellular wheel 4.
  • the two bearing bodies 32 for the second cellular wheel 4 are each guided with three slide bushes 41 formed on them on a total of three guide rods 42 which are parallel to the horizontal Axis 5 are arranged at equal distances from this and are attached with their ends in the frame 1.
  • a central threaded sleeve 43 is also attached to each of the two hubs 31. With these threaded bushes 43, one of which is right-handed and the other of which is left-handed, and both of which have the same pitches in terms of amount, a corresponding thread cut 44 is in engagement on a common spindle 45.
  • the spindle 45 extends along the horizontal axis 5 and is axially immovably mounted in the frame 1.
  • the two bearing bodies 32 By rotating the spindle 45 in one direction or the other, the two bearing bodies 32, and thus the two halves 4 ′ and 4 ′′ of the second cell wheel 4, can be adjusted toward or away from one another in accordance with the format of the printed products P to be trimmed.
  • a handwheel or, for example, an electric servo motor can be provided for rotating the spindle 45.
  • Each of the two cutter bars 38 carries at its free end remote from the associated cutter bearing 37 a guide member 46, in the example shown an eccentric, that is to say adjustable, roller which is freely rotatably mounted on the cutter bar 38.
  • the guide member 46 runs in the operating position of the associated cutter bar 38 on a flat annular tread 47 on the ring gear 17 of the associated half of the second cell wheel 4. This ensures that each of the fixed counter knife 39 in its operating position with the associated rotating knives 36 one exactly adjustable and constant cutting gap.
  • each cutter bar 38 is assigned a pressing and pivoting device, which approximately fastens to the associated bearing body 32 radial support beam 48 and one of these parallel to the horizontal Axis 5 has cantilevered arm 49.
  • a hydraulic or pneumatic cylinder 50 is mounted on the support beam 48, the piston rod of which forms an actuator 51 and is connected to a link 53 and a coupling member 54 by a joint 52.
  • the handlebar 53 is mounted on the bracket 49 with its end facing away from the joint 52 and, together with the coupling member 54, forms a toggle lever.
  • the coupling member 54 is composed of a housing 55 which is mounted on the joint 52 and in which a plunger 56 is displaceably guided and is biased in the axial direction by a spring arrangement 57. The plunger 56 is articulated to the associated cutter bar 38.
  • the piston rod forming the actuator 51 In the operating position of the counter knife 39, the piston rod forming the actuator 51 is retracted.
  • the toggle lever formed by the handlebar 53 and coupling member 54 assumes a somewhat more than extended dead center position.
  • the force with which the roller 46 is pressed against the running surface 47 is determined by the prestressing of the spring arrangement 57.
  • the cutting forces acting on the counter knife 39 during operation are transmitted from the knife bar 38 to a stationary support body 58 which is made of plastic with good sliding properties. If the relevant counter knife 39 is to be pivoted away from the associated cellular wheel half of the second cellular wheel 4, the actuator 51 is extended so that the toggle lever 53, 54 assumes an angled position according to FIG. 7.
  • each of the counter knives 39 is fastened to a holder 59 which is connected to the associated knife bar 38 by an overload safety device 60.
  • the overload safety device 60 includes a front seat 61 and a rear seat 62 on the cutter bar 38, as well as a depression 63 formed between these seats 61 and 62 and a depression 64 in the cutter bar 38 formed behind the rear seat 62.
  • the seats 61 and 62 normally lie on the seats 61 and 62 a projection 65 or 66 on, which is formed on the bracket 59 and through a recess 67 are separated from each other.
  • a plurality of tie rods 68 are screwed into the holder 59, each of which extends through an elongated hole 69 in the cutter bar 38 and is prestressed by a spring arrangement 70 on the side facing away from the holder 59.
  • the spring arrangements 70 are each formed by a plate spring assembly, as can be seen above all from FIG. 9.
  • the bracket 59 also has a front extension 71 which interacts with sensors 72 attached to the associated cutter bar 38.
  • the approach 71 disappears from the monitoring area of the associated sensors 72, so that they emit a signal which is evaluated as an emergency signal and is used to reverse the associated cylinder 50, so that the actuator 51 extends and thereby the cutter bar 38 in question into its rest position 7 is pivoted.
  • a mouthpiece 73 of a system for sucking off cut paper strips is also attached.
  • the mouthpiece 73 is a box elongated in the radial direction of the second cellular wheel 4, which is open towards the associated counter knife 39 and is connected to a suction line 74 in its radially inner end region.
  • each of the cells 35 of the second cell wheel 4 is limited by a stop bar 75 parallel to its axis 5. All stop bars 75 are arranged at the same distance from the axis 5 such that the printed products P can be inserted just deep enough into one of the cells 35 for trimming their lateral edges.
  • the length of the rotating knife 36 and the counter knife 39 is dimensioned so that printed products P of different heights - measured as the distance between the fold and the flower - can be trimmed laterally in the same way.
  • a wall section 76 is fastened to each of the spokes 33. If the two cell wheel halves 4 'and 4' 'of the second cell wheel 4 are set for trimming large-format printed products and are thus at a large distance from one another, for example as shown in FIG. 4 A, a small space can remain between associated wall sections 76, which is not harmful . When the two cell wheel halves 4 'and 4' 'are brought closer together for the trimming of printed products of smaller format, the wall sections 76 slide telescopically one above the other.
  • Each of the cells 35 contains a pair of pressure strips 77 which are arranged in parallel and in the vicinity of one of the associated rotating knives 36 in such a way that the printed product P introduced into the cell in question along its two edges, which are to be trimmed, between each of the Press bars 77 and the adjacent knife 36 is clamped before trimming begins.
  • each of the pressure bars 77 is mounted on a link 79 by means of a joint 78, which in turn is mounted on a two-armed lever 81 by means of a bearing 80.
  • the two-armed lever 81 is mounted on the adjacent spoke 33 by means of a bearing 82.
  • the geometric axes of the bearings 80 and 82 are parallel to the axis 5 of the second cellular wheel 4.
  • the link 79 has a projection 83 projecting essentially radially outwards; between this and the pressure bar 77, a spring 84 is clamped, which is a helical compression spring in the example shown.
  • the swivel range of the two-armed lever 81 is limited by a tie rod 85.
  • a spring 86 - a helical compression spring is shown, through which the tie rod 85 extends - the two-armed lever 81 is pretensioned in such a way that it strives to press the pressure bar 77 connected to it from the one in front of it - in FIG. 11 to the right of it - To pull away arranged spoke 33.
  • a spring 87 acts in the same sense and is clamped between the link 79 and the spoke 33 lying in front of it.
  • the pivoting of the handlebar 79 is limited by an adjustable stop 88 on the spoke 33 arranged behind it - to the left of it in FIG. 11.
  • a roller 89 is mounted, which is held against the associated bearing body 32 by the pressure of the spring 86 on a control cam 90.
  • the printed products P adapted to their thickness, can be securely pressed into a predetermined position in the cell 35 receiving them.
  • Untrimmed printed products P are brought in by the conveyor 6 with their folds hanging down and dropped into one cell 25 of the first cell wheel 2.
  • the case is limited by a support 91 in the form of arcuate strips, which are fastened to the frame 1 in a feed area below the first cell wheel 2 so that they can be adjusted in height.
  • each of the printed products is clamped in its cell 25 and then on its flower trimmed and then released again, so that the printed product slides a little further down until it rests with its fold on an arcuate rail 92 arranged under the first cell wheel 2.
  • the rail 92 can also be adjusted in height in order to adapt to different printed products and is also attached to the frame 1 in an adjustable manner in the circumferential direction. The end of the rail 92 is bent downwards. As soon as a printed product P has reached this end, it falls out of its cell 25 into a cell 35 of the second cell wheel 4 that is passing below it at the same instant.
  • the printed product P is clamped in the cell 35 by means of the two pressure strips 77 and then trimmed at its two lateral edges.
  • the pressure strips 77 are controlled by the control cams 90 in such a way that they release the now-trimmed printed product P again, so that it now slips out of the cell 35 under the influence of gravity in a lower region of the second cell wheel 4 until the flower of the Printed product abuts against an arcuate support 93 arranged there.
  • This support 93 ends in FIG. 1 to the right of the second cell wheel 4 in an area slightly below its axis 5, where the printed product P can no longer slide out of the cell 35 by itself.
  • the printed product P now projects radially beyond the wall sections 76 to such an extent that it can be gripped by a gripper 94 of the discharge conveyor 7 and transported further.
