Definitions

  • the present invention relates to a device and a method for rolling a multi-sheet, folded printed product, in particular a newspaper or magazine, and wrapping the roll with an enveloping element holding the roll and protecting the printed product according to the preamble of claims 1 and 13, respectively.
  • a device and a method of this type is known from US-A-4,748,793.
  • This has a fork-like winding mandrel, which can be rotated about its longitudinal axis, into the mandrel gap of which a newspaper is inserted and brought into contact for alignment with stops.
  • a delivery device for feeding a film-like envelope element Above the winding mandrel is a delivery device for feeding a film-like envelope element.
  • This has a pivotably mounted feed arm, which introduces the edge section of a film web unwound from a supply roll into the gap between the parts of the newspaper which have already been partially rolled and which face one another. The film web is then rolled up together with the newspaper, a desired tension in the film being built up and maintained via a pair of dancer rolls.
  • the roll is further wrapped with the film web and when the feed arm is swung back, the film web is cut by means of a heating wire, so that the rolled end section forms a sleeve for the printed product.
  • the overlapping areas of the film automatically adhere to each other and hold the roll together.
  • the pressure rollers which press the newspaper against the mandrel as it rolls, are swiveled away from the roll and this from the roll The winding mandrel is pulled off in the axial direction.
  • This known device requires manual operation and has a considerable cycle time.
  • the printed product to be rolled is introduced by means of a belt conveyor arrangement together with the enveloping element into the mandrel gap of a winding mandrel with its leading end region. Since the wrapping element wraps around the leading end region of the printed product, it is safely taken along with the printed product and inserted into the mandrel gap. The wrapping element is inserted into the conveying path of the printed product from that side that it is external to the printed product when it is rolled up. As a result, short cycle times are achieved, since after the printed product has rolled, only a relatively narrow rear edge section protruding beyond the end of the printed product has to be rolled up further in order to ensure the connection of this edge section to a region of the wrapping element that has already been rolled up.
  • the device shown in FIGS. 1 and 2 has a roll-up device 10 with approximately two coaxial, essentially cylindrical winding mandrels 12, which are provided with mandrel gaps 14 which are open and aligned with one another.
  • the winding mandrels 12 are preceded by a belt conveyor arrangement 16 which defines a conveying path 18 for a printed product 20 to be rolled up and has a conveying direction designated by the arrow F, which runs essentially horizontally and at right angles to the axis 12 'of the winding mandrels 12.
  • winding mandrels 12 there is a pivotably mounted pressing device 22 and, seen in the conveying direction F, the winding mandrels 12 are followed by a cantilever element 24 in order to convey the printed product 20 rolled into a roll 26 and wrapped by means of a wrapping element 28 away from the winding device 10.
  • a delivery device 30 opens into the conveyor path 18 from below.
  • the enveloping element 28 is formed in each case by a section of a film web 32, which is separated from the latter by means of a cutting device 34.
  • the delivery device 30 is designed to hold the enveloping element 28 with its leading edge section 36 (see FIG. 3) leading in the delivery direction Z (see FIG. 3), so that a printed product 20 fed in the conveying direction F by means of a feed belt conveyor 38 with its leading edge 40 runs onto the edge section 36.
  • the edge section 36 is then placed against the printed product 20 so that it envelops the leading end region 42 of the printed product 20, (FIG. 4), together with this, by means of a belt conveyor 44 (FIG. 1), into the mandrel gap 14 of the winding mandrels 12 to become (Fig. 5).
  • the wrapping element 28 (FIG.
  • the wrapping element 28 is located radially on the outside with respect to the printed product 20 during rolling.
  • the belt conveyor 44 has a plurality of endless conveyor belts 48 which are parallel to one another and which are guided around common deflecting rollers 50, 50 'spaced apart from one another in the conveying direction F.
  • deflecting rollers 50, 50 ' are mounted in a generally known manner on a frame 52 so that they can rotate freely, and the deflecting roller 50' adjacent to the winding mandrels 12 is connected to a drive motor 56 via a freewheel 54 which acts in the conveying direction F and is only indicated schematically.
  • the belt conveyor 44 and the winding mandrels 12 are immediately followed by the cantilever element 24 with an endless cantilever belt 58.
  • the cantilever belt 58 is guided around deflecting rollers 60, 60 ', which are also fixedly mounted on the frame 52, the deflecting roller 60 adjacent to the winding mandrels 12 being connected to the drive motor 56 via a further freewheel 54', only indicated schematically and also acting in the conveying direction F.
  • the cantilever belt 58 consists of a plurality of endless ribbons 58 'parallel to one another.
  • a drive shaft 62 is mounted on the frame 52 via a freewheel 64 acting in the direction of rotation D, which can be connected via a generally known single-speed clutch 66 to a schematically indicated chain drive 68, which is connected to the drive motor 56.
  • the coupling part 70 of the single-speed clutch 66 which is wedged onto the drive shaft 62, has a stop 72 which interacts with a counter-stop 74 which moves into and out of the way of the stop by means of a quick-shift cylinder-piston unit 72 can be brought.
  • the drive shaft 62 is held in a precisely defined rotational position and the freewheel 64 prevents the stop 72 from running away from the counter-stop 74 counter to the direction of rotation D; If the counterstop 74 is moved away from the stop 72, the single-speed clutch 66 couples the drive shaft 62 to the chain drive 68.
  • Two bearing sleeves 78 are seated on the drive shaft 62, each of which is connected to it in a rotationally fixed but slidable manner in the axial direction by means of a groove-wedge connection 80.
  • a single-armed lever 82 is freely rotatably supported, and these levers 82, in turn, carry the winding mandrels 12 at their free ends, in a freely rotatable manner relevant winding mandrel 12 wedged gear 84 'is connected.
  • the winding mandrels 12 are thus rigidly coupled to the drive shaft 62 in terms of drive.
  • the bearing sleeves 78 have, between the lever 82 and the gear 84, a circumferential groove 88 which is open in the radial direction towards the outside and into which two diametrically opposed sliding shoes 90 engage.
  • the slide shoes 90 assigned to a bearing sleeve 78 are fastened to an approximately U-shaped control bracket 92 which engages around the drive shaft 62 from above and is connected to a cylinder-piston unit 94 which acts in the direction of the axis 62 'of the drive shaft 60.
  • the two cylinder-piston units 94 which are also attached to the frame 52, act in the opposite direction in order to simultaneously move the two mandrels 12 in the direction of the axis 62 '.
  • the axis 12 'of the mandrels 12 runs parallel to the axis 62'.
  • the pressing device 22 has a plurality of endless pressing tapes 96 which are parallel to one another and which are guided around two deflecting rollers 98, 98 '.
  • the deflection roller 98 is freely rotatable on the drive shaft 62.
  • the deflection roller 98 is encompassed in the central region between two pressure tapes 96 by a brake band 100 of a controllable braking device 102, which is supported at one end in a stationary manner and at the other end is connected to another cylinder-piston unit 104 that also switches quickly.
  • the brake band 100 can be applied to the deflection roller 98 by means of the cylinder-piston unit 104.
  • lever-like bearing plates 106 are supported on the drive shaft 62 in a freely rotatable manner, on which the deflection roller 98 'is freely rotatably mounted in the free end region.
  • the winding mandrels 12 are located approximately in the central region of the lower pressing-on strand 96 ′ of the pressing tapes 96.
  • stop elements 108 protrude which, when the pressing device 22 is pivoted into the lower end position (shown with dashed lines in FIG. 1), engage around the winding mandrels 12 in a U-shaped manner from above.
  • These stop elements 108 serve to prevent entrainment of the roller 26 in the direction of the axis 12 ′ when the winding mandrels 12 are pulled out of the coated roller 26 in the axial direction.
  • the pressing device 22 In its lower end position, the pressing device 22 is supported on the winding mandrels 12 via the lower runs 96 'of the pressing tapes 96, the lower end position of which is defined, for example, by stop elements 110 which interact with the levers 82.
  • the winding mandrels 12 In this lower end position, the winding mandrels 12 are located at the deflecting roller 50 ′ and, when the stop 72 rests against the counter stop 74, are aligned such that the mandrel gaps 14 are aligned with the conveying path 18 defined by the upper runs 48 ′ of the conveyor belts 48. It is also conceivable that the winding mandrels 12 are supported in their lower end position directly on the bearing arrangement for the conveyor belts 48 in the region of the deflection roller 50 '.
  • the delivery device 30 has an endless delivery belt 112 which is guided around rollers 114, 114 '.

  • the serrated knife 124 has a blow nozzle arrangement 130 which can be connected to a pressure source (not shown) and whose blow nozzles are directed in such a way that the air jet blows slightly against the conveying direction F and obliquely upwards over the roller 114 of the delivery device 30, see FIGS. 3, 6 and 7. With the air jet of this blowing nozzle arrangement 130, the edge section 36 of the enveloping element 28 is held, crossing the conveying path 18, projecting in the upward direction.
  • the feed belt conveyor 38 is also driven in the conveying direction F by the drive motor 56.

  • the product recognition device 132 sends a signal to the control device 134 as soon as a printed product 20 has reached the end region of the feed belt conveyor 38. From this moment on, the control device integrates the signal of the tachometer generator 136, whereby the position of the leading edge 40 of the printed product 20 of the control device 134 is always known. If the leading edge 40 now reaches the roller 114, the start-stop clutch 116 is closed and the delivery belt 112 is driven in the delivery direction Z at a speed which corresponds approximately to the conveying speed v. When the leading edge 40 approaches the wrapping element 28 its edge section 36 due to the air jet and the adhesiveness of the film material on the top of the leading end region 42 of the printed product 20 and wraps around it, as can be seen from FIG. 4. Then the airflow is turned off.
  • the printed product 20 and the film web 32 are now pressed by the belt conveyor 44 and the pressure tapes 96 in the direction against the winding mandrels 12, so that a full roll-up takes place.
  • the winding mandrels 12 are now pivoted clockwise by pivoting the lever 82 and the pressing device 22 is also pivoted clockwise, as is indicated by dash-dotted lines for the pressing device 22 in FIG. 1; the enveloping element 28 also comes into contact with the cantilever belt 58 and the support then also takes place from the latter.
