Definitions

  • US-A-4 390 138 describes a reel-up substantially in accordance with the reel-up defined by the preamble of claim 1.
  • the lifting device of the known reel-up has lifting elements and actuators. However, the lifting elements are suspended from roller chains and are guided for vertical movement by guideways provided on the inner sides of vertical stands. The lifting elements are thus arranged inside the reel-up for vertical movement between a lower position and upper position by means of cylinders and said roller chains.
  • One object of the present invention is therefore to provide an improved reel-up which enables manual handling of the reeling drums to be greatly reduced.
  • the reel-up according to the invention is characterized in that
  • a surface winding drum 9 is rotatably journalled at the stand parts 6, 7 in the upstream end of the reel-up 1.
  • a drive means (not shown) gives the surface winding drum 9 a peripheral speed corresponding to the speed of the paper web 2.
  • the stand rails 8 are arranged at a distance from each other which is somewhat greater than the breadth of the paper web 2.
  • the reeling drum 4 is provided at each end with a braking drum 10 comprising a coupling member 11 and a bearing housing 12 situated inside the coupling member 11, provided with a peripheral groove 13.
  • the reeling drum 4 rolls along the stand parts 6, 7, its peripheral grooves 13 cooperating with the stand rails 8.
  • each reeling drum 4 is provided with two form-stable cylindrical cores 14. Alternatively only one core may be used, as shown in Figure 1.
  • the reeling drum 4 has expandable plates which in active state, i.e. expanded, lock the cores 14 to the reeling drum and which in inactive state, i.e. unexpanded, release the core from the reel
  • the reel-up is provided with a feeding device 22 for feeding a reeling drum 4 along the rails 21 when the reeling drum has been lifted and placed on the rails 21.
  • the feeding device 22 comprises a feeder 23 arranged close to each rail 21 to be brought into abutment with a reeling drum when it is to be fed forward.
  • the feeding device also comprises a pneumatic actuator 24 arranged on the outer side of each support element 19 to move the feeder 23 to and fro along the rail 21. It will be understood that the two actuators 24 are synchronised with each other.
  • the reel-up is provided with a pair of lowering arms 32 (see Figures 14 and 15), which are pivotably mounted on the pillars 17 located there. With the aid of these lowering arms 32 a reeling drum 4 is transferred from the exit 29 of the drum stock 15 down to a primary system for receipt of a reeling drum 4 which is arranged in connection with the surface winding drum 9.
  • a pair of actuators 34 is arranged at the lowering arms 32, extending between each one lowering arm 32 and the stand part 6, 7, respectively.
  • the receiving primary system (see Figures 2-5) comprises two primary arms 38 arranged to receive the new reeling drum 4 either directly from the lowering arms 32 or from a pair of lowering surfaces 39 arranged at each end of the surface winding drum 9 and on a level with its upper side, when the paper reel 3 growing around the reeling drum 4 situated downstream approaches a certain predetermined size (see Figure 6).
  • the reel-up 1 further comprises a secondary system having a pair of linearly movable secondary carriages 42 (see Figures 6 and 7) which are displaceable by means of actuators 44 along a track or tracks 45 at each stand part 6, 7.
  • the primary arms 38 are arranged to bring the reeling drum 4 into contact with the surface winding drum 9 over which the paper web 2 runs, in order to commence reeling of the paper web 2. While a number of turns of the paper web 2 are wound onto the reeling drum 4, the latter is conveyed by the primary arms 38, along the periphery of the surface winding drum 9 down to the stand parts 6, 7, see Figures 4 and 5, where the secondary system is arranged to take over control of the reeling drum 4 during continued reeling.
  • the actuator 44 for the secondary carriage 42 (see Figure 6) consists of a hydraulic or pneumatic cylinder which is secured by one end to the secondary carriage 42 and by its other end to the stand 6, 7.
  • the movements of the two secondary carriages 42 along the tracks 45 are thus synchronised with each other and with the increasing diameter of the paper reel 3 so that the secondary carriages 42 follow the paper reel 3 along its horizontal movement during the continued reeling to a finished jumbo roll 3.
  • Each primary and secondary system comprises gripping members formed by a locking device 47 and a press device 48.
  • the gripping members support the reeling drum 4 while at the same time allowing it to rotate freely inside the gripping members.
  • the gripping members of the secondary system is arranged to receive the reeling drum 4 from the gripping members of the primary system so that the end parts of the reeling drum 4 rest with their bearing housings 12 directly on the rails 8. They may alternatively rest on separate rails.
  • the press device 48 is arranged to act against the bearing housing 12 during reeling, so that a desired and adjustable linear pressure is maintained in the nip between the surface winding drum 9 and the growing paper reel 3.
  • the braking device 50 comprises braking arms 51 with associated actuators and brake linings.
  • the cut end of the web is also taped to the surface of the jumbo roll 3 in the braking station 49.
  • the braking station 49 also comprises an ejection device 55 which causes the paper real 3 to roll towards the downstream end.
  • a stop 56 and a shock absorber 57 are provided at the downstream end of each stand part 6, 7 to restrain the horizontal movement of the paper reel 3 (see Figures 16 and 17).
  • a cutting device Upstream of the surface winding drum 9 is a cutting device, not shown, which slits the paper web 2 into two web sections 52, 53, see Figure 5, having substantially the same breadth as the length of the cores 14 threaded onto the reeling drum 4, thus allowing each web section 52, 53 to be reeled onto its own core 14.
  • the reel-up also comprises a multi-functional handling station 54 situated at its downstream end for handling finished reels of paper 3, reeling drums 4 and cores 14 therefor.
  • the handling station 54 comprises a lifting table 58 (see Figure 7) extending between the stand parts 6, 7.
  • the lifting table 58 is vertically movable and tiltable with the aid of a plurality of vertical actuators 59 distributed along its long sides.
  • the lifting table 58 is provided on its upper side, in the vicinity of the driving side, with suitable sleeve stops 110.
  • the lifting table 58 has concave or arched form (see Figure 13) so that the two jumbo rolls 61 formed after withdrawal of the reeling drum 4 are safely retained.
  • the lifting table 58 is also arranged, with the help of actuators 59, to tip the jumbo rolls 61 in downstream direction either directly to a suitable transport device (not shown), such as a travelling carriage or a conveyor belt, or to a bench 71 (see Figures 7 and 15) from which the jumbo rolls 61 are then transported further, either to a subsequent work station usually including some type of conversion or rewinding station, or to intermediate storage with the aid of an overhead crane or truck, for instance. The cores are then returned from this station to the reel-up.
  • a suitable transport device not shown
  • a travelling carriage or a conveyor belt or to a bench 71 (see Figures 7 and 15) from which the jumbo rolls 61 are then transported further, either to a subsequent work station usually including some type of conversion or rewinding station, or to intermediate storage with the
  • the handling station 54 further comprises a core-feeding device 72 (see Figure 9) provided with a horizontal, longitudinally extending channel 78 arranged at right angles to the machine direction and situated below the drum moving device 60.
  • the channel 78 is open at its inner end, situated in an opening 111 in the stand part 6.
  • a feeder 82 is slidably journalled in the channel 78.
  • a motor 83 is mounted at the inner end portion of the channel 78 to drive a cogged belt (not shown) which is rigidly connected to the feeder 82 in order to move the feeder 82 to and fro in the channel 78.
  • the starting position of the feeder 82 is behind the core 14 and, when actuated, it will press against the rear end of the core 14 to feed it through the opening 111 in the stand part 6 and out onto the lifting table 58.
  • One side wall of the channel 78 is provided with an inlet opening 79 which is slightly longer than a core 14.
  • the core-feeding device 72 is also provided with a magazine for cores 14 to be used.
  • the magazine includes a ramp 73 arranged opposite the inlet opening 79 of the channel 78 and inclined towards this opening.
  • the ramp 73 is provided with side plates 75 towards which the ends of the cores face and which serve as guides for the cores 14.
  • a stop mechanism 76 (see Figure 8) is arranged at the outlet end of the ramp 73 which in closed position retains the cores 14 on the ramp 73 and in open position allows the lowermost core 14 to roll down into the channel 78, after which it returns to closed position.
  • the core-feeding device 72 comprises control equipment (not shown) with associated detectors at the inlet and outlet openings for the stored cores.
  • the handling station 54 further comprises a lifting device 84 to lift a reeling drum 4 provided with core(s) from the lifting table 58 to the drum stock 15 at the top of the reel-up (see Figures 8, 9, 16, 17).
  • the lifting device 84 comprises two lifting elements 85, in the embodiment shown constituting Z-shaped lifting arms pivotably journalled each in its own support element 19.
  • Each lifting arm is made in one piece and has an outer lifting arm part 86, an inner lifting arm part 87 and an inner journalling part 88.
  • the two lifting arm parts 86, 87 and the journalling part 88 together form said Z-shape.
  • the outer and inner arm parts 86, 87 form an acute angle with each other and define a V-shaped pocket 89 between them for receipt of an end portion of a reeling drum 4.
  • the inner lifting arm part 87 and the journalling part 88 form substantially a right angle with each other.
  • An actuator 90 in the form of a power cylinder is joined by one end to the inner journalling part 88 spaced from its journalling shaft 112 and with its other end at an attachment element 113 rigidly mounted on the support element 19 (see Figures 8 and 9).
  • the force lines of the power cylinders 90 are in their extensions situated at a distance from the journalling shafts 112 of the lifting arms 85 so that the requisite leverage is obtained when activating the lifting arms 85.
  • the free end of the outer lifting arm part 86 is provided with an upwardly directed stop 91, seen in the lower starting position of the lifting arm, to retain a reeling drum 4 on the outer lifting arm part 86 when lifting is to commence.
  • the lifting arms 85 are joined together by means of a parallel shaft 96, thus ensuring that the lifting arms 85 are turned synchronously.
  • the lifting arms 85 are situated in the machine direction and are parallel with each other.
  • Their outer and inner lifting arm parts 86, 87 form free edges along which the reeling drum 4 rolls during commencement and completion of the lift.
  • a shock absorber 92 (see Figure 17) is arranged at the transition between the outer and inner lifting arm parts 86, 87 in order to prevent the lifting arms 85 from being damaged as a result of the impact energy of the reeling drums 4 against the lifting arms 85, which shock absorber 92 comprises a curved impact absorber 93 and a damping member 94 for this in the form of a hydraulic cylinder.
  • a plurality of detectors 40, 41 are arranged on or close to each lifting arm 85 to detect some of the positions of the reeling drum 4 in the lifting arm 85 during its rolling movement therein.
  • the detectors 40 are arranged to detect the position of the reeling drum in said V-shaped pocket to obtain a signal for continued lifting of the reeling drum 4 to the level of the rails 21 of the drum stock 15, i.e. the presence of both ends of the reeling drum 4 is registered by the detectors 40.
  • the detectors 41 are arranged at the end of the inner journalling part 87 to detect the completion of the lift and subsequent delivery of the reeling drum 4 to the rails 21 of the drum stock 15 so that the lifting arms 85 can return to their lower fetching positions.
  • a shock absorber 95 is also arranged at the end of the inner journalling part 87 in order to dampen the rolling-off movement of the reeling drum 4 from the lifting arms 85 onto the rails 21 of the drum stock 15.
  • Blocking members 98 are arranged at suitable points along the rails 21, which blocking members 98 are arranged to be folded away under the influence of a reeling drum 4 rolling on the rails and then to return to their blocking position in which the reeling drum 4 is prevented from rolling backwards.
  • the blocking members may be provided with springs or counterweights.
  • the primary arms 38 are in their upper, receiving position with their gripping members above the surface winding drum 9, said gripping member being open and ready to receive a first reeling drum 4.
  • the secondary carriages 42 are in their upstream positions close to the surface winding drum 9.
  • a first reeling drum 4 is located on the upper rails 21 above the surface winding drum 9, ready to be gripped by the lowering arms 32, the latter being still in their lowermost position.
  • the braking station 49 Downstream in the reel-up 1 the braking station 49 is ready with its braking arm 51, to receive and retard a finished jumbo roll 3.
  • the cutting device has been started but is not in production position.
  • the first core 14 waits in its feed-in position in the core-feeding device 72 (see Figure 3).
  • the lifting table 58 is in its lowermost position and the furthermost core stop 110, in the direction of insertion of the core 14, is set to receive the first core 14 in a position on the lifting table 58 suited for the actual dividing of the paper web 2.
  • a reeling drum 4, as yet without a core, is in the feed-in position in the drum moving device 60 at the side of the reel-up.
  • the lifting arms 85 are in their lowermost position.
  • the feeder 23 of the feeding device 22 is in a ready position at the entry end 99 of the drum stock 15 (see Figure 16).
  • the lowering arms 32 move up to the drum stock 15 and the outermost of the reeling drums 4 in the drum stock 15 is lifted over the end stop 30 of the drum stock 15 by the lowering arms 32 (see Figures 1, 14, 15), after which the reeling drum 4 will roll along the roll surfaces 35 of the lowering arms 32 to the shock absorbers 37.
  • the detectors 33 indicate when the reeling drum has reached the correct position, whereupon the lowering arms 32 are turned down towards the lowering surfaces 39 (see Figure 14) of the primary system, a distance above the surface winding drum 9, where the gripping devices of the primary arms 38 take over the reeling drum 4.
  • the press device 48 and locking device 47 of the primary arms 38 together encompass the reeling drum 4 and position it in its starting position.
  • the reeling drum 4 is then accelerated up to the same peripheral speed as that of the surface winding drum 9 in order to minimise the friction when these are brought into contact with each other.
  • a wrapping occurs and the paper web 2 is transferred in suitable manner to the reeling drum 4, e.g. the paper reel 3 growing downstream (see Figure 6) can be retarded so that a surplus appears in the web 2 which is drawn into the nip and then cut off.
  • the wrapping can be effected by glue or tape having been applied on the cores 14 of the reeling drum 4.
  • the secondary carriages 42 While the paper reel 3 is growing the primary arms 38 first and then, after delivery of the reeling drum 4 to the secondary system, the secondary carriages 42, are gradually positioned outwardly from the surface winding drum 9. For the secondary system this means that the secondary carriages 42 move synchronously horizontally along the stand rails 8 (see Figure 6).
  • the lifting table 58 and paper reel 3 are raised a short way from the rails 8 of the stand parts 6, 7 so that the reeling drum 4 is free from the stand 5 and the reeling drum 4 can be removed (see Figures 10 to 13) by its braking drum 10 on the operator side 6 being gripped by the gripping members 66 of the drum moving device 60.
  • the plates of the reeling drum 4 are loosened, thus disengaging the cores 14, after which the gripping member 66 pulls out the reeling drum 4 to a rest position on the support element 62 (see Figures 11 and 13).
  • the jumbo rolls 61 now released on the lifting table 58 are tipped out onto the bench 71 (see Figure 15) by the inner and outer rows of actuators 59 of the lifting table 58 (see Figure 7) being activated in opposite directions.
  • a core 14 is caused to roll from the ramp 73 to the channel 78 situated downstream in rolling-out direction.
  • the core 14 is then fed along the channel 78 with the aid of the feeder 82 in axial direction to the lifting table 58 (see Figure 5).
  • the core stop 110 of the lifting table 58 and its concave shape guarantee that the cores 14 arrive in the correct position on the lifting table 58.
  • the actuators 90 of the lifting device 84 are activated during a short interval so that a first initial upward turning movement is achieved.
  • the reeling drum 4 is gripped by each stop 91 on the lifting arms 85 and lifted a short distance so that the reeling drum 4 will be caused to roll slowly towards the pockets 89 formed between the outer and inner lifting arm parts 86, 87 (see Figures 8 and 9).
  • the lifting table 58 is lowered to its lowermost position by the lifting device 84.
  • the impact energy of the drum 4 caused by the rolling is taken up by the shock absorbers 92 (see Figure 17) and when both ends of the reeling drum 4 have thus arrived in said pockets 89, the detectors 40 in the pockets indicate that the drum 4 is in the correct position for lifting.
  • the reeling drum 4 passes the blocking members 98 arranged on each rail 21 which, after having been folded aside during passage of the drum, are turned back to their upright blocking positions thereby preventing the reeling drum 4 from rolling back. Finally, the feeders 23 move the reeling drum 4 forward to the outlet 29 of the drum stock 15, either as far as the reeling drums 4 already there or to the end stop 30 (see Figure 17).
  • the detectors 31 indicate in the first case that both ends of the reeling drum 4 have reached the correct position.
  • the above-mentioned actuators may be hydraulic, pneumatic, electric or mechanical actuators.
  • Some or all of the parts of the handling station situated on the operator side may be placed on the drive side of the reel-up if so desired.
  • Additional detectors to those described may be arranged at suitable points in the reel-up to detect the beginning or end of various phases or movements during reeling of the paper web and handling the reeling drums, cores and paper reels.
