Definitions

  • the present invention relates to a reel-up in a paper machine for manufacturing a paper web which is reeled onto reeling drums provided with cores to form reels of paper, said reel-up having an upstream end and a downstream end and comprising:
  • the continuous reeling occurs in the reel-up in the paper machine and the reel of paper leaving the reel-up is usually called a jumbo roll.
  • This may either consist of a single reel with a breadth corresponding to the full machine breadth, or of several reels, the paper web being divided into one or more web sections which are reeled individually onto cores on a reeling drum provided with several cores.
  • empty reeling drums are all the time supplied from a stock of drums. This stock of drums is arranged in close connection to the surface winding drum at the upstream end of the reel-up and at a level just above the production line of the reel-up in order to save space.
  • the reeling drums are lowered from the stock of drums with the aid of lowering arms, to the surface winding drum of the reel-up where the process of reeling the paper web to finished reel of paper again commences.
  • the stock of drums must be replenished as the reeling drums are used in the reel-up.
  • a manual system is still used to a great extent to return the reeling drum removed from the finished paper reel to the stock of reeling drums. This is achieved by pulling or pressing the reeling drum out of the paper reel with the aid of a drum moving device arranged at the downstream end of the reel-up.
  • the reeling drum thus removed is then provided with one or more new cores and returned to the stock of drums.
  • the cores have comparatively very large diameter as well as a length usually reaching several meters and cannot therefore be moved manually to any great extent. They must therefore be transported to the reel-up with the aid of an overhead crane or some other suitable transport device, such as a truck.
  • the reeling drum provided with a core is lifted by an overhead crane to the drum stock situated above the reel-up, a machine operator first manually applying the gripping means of the crane on the reeling drum selected and accompanying the reeling drum along its transport distance until it can be placed in the correct position in the drum stock. Alternatively a second machine operator may be positioned up by the drum stock to receive and disengage the raised reeling drum. It will be readily understood that the manual manipulation of the reeling drums described above is both time-consuming and laborious, and thus expensive. Furthermore, all manual work in or close to the paper machine during operation, including transport of heavy objects such as reeling drums suspended in overhead cranes, always entails risks for the operator.
  • 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 the multi-functional handling station is also provided with a lifting device comprising
  • the invention provides a reel-up in which, for the first time, it is possible to move the reeling drums in an automatic cycle, i.e. without manual help during the actual transfer and without the use of external handing equipment and vehicles for transfer of the reeling drums in the cycle.
  • the only manual assistance entails activation and de-activation of the engagement between the cores and the reeling drums. However, this has nothing to do with the actual movement of the reeling drums in the cycle.
  • Figure 1 shows schematically in perspective parts of a reel-up 1 in a paper machine in which paper is manufactured in a continuous web 2 which is reeled onto a rotatable reeling drum 4 in the reel-up 1 to form a reel of paper 3.
  • the reel-up 1 comprises a stand 5 with first and second longitudinally extending, parallel stand parts 6, 7 along which the paper reels 3 roll on top of horizontal rails 8 rigidly mounted above each stand part 6, 7 and forming a lower pair of rails in the reel-up.
  • the reel-up has a reeling station arranged immediately downstream of the upstream end of the reel-up. In the embodiment shown the reeling station is constructed as follows.
  • 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 stand is provided with a horizontal, frame-like top stand part 16 supported by a plurality of pillars 17 and comprising two parallel beams 18 extending in machine direction.
  • a support element 19 is arranged on the inside of each beam 18 and rigidly joined to this by crossbars 20.
  • the support elements 19 are spaced from the beam 18 and provided with rails 21 situated at a higher level than the beams 18.
  • the rails 21 are arranged to carry reeling drums 4 provided with cores, these drums forming a stock 15 for the continuous operation of the reel-up.
  • the upper rails 21 are dimensioned to fit with clearance into the peripheral grooves 13 of the reeling drums 4.
  • the upper rails 21 and lower rails 8 are situated in pairs in a common vertical plane.
  • 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 actuator 24 consists of a cylinder 28 and a piston (not shown) movable therein, with which the feeder 23 is connected via a connection piece 25 (see Figure 16), extending through a longitudinally extending, self-sealing groove (not shown) in the cylinder 28.
  • the feeder 23 is pivotably arranged to be swung down to an inactive position under the influence of a reeling drum 4, when the feeder 23 is returned to fetch this reeling drum.
  • the feeder 23 is arranged to be automatically swung up to its active position by means of springs. Counterweights may be used instead of springs.
  • An end stop 30 is arranged at each rail 21 to stop the forward feeding when the reeling drum 4 encounters the end stop 30.
  • Detectors 31 are also provided close to these end stops 30, arranged on the inner side of the support elements 19, to detect the presence and position of the foremost reeling drum 4.
  • 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.
  • Each lowering arm 32 comprises a roll surface 35 extending along the upper edge of the arm 32 from its free, outer end and being defined by an outer grab hook 36 and an inner drum shock absorber 37 (see Figure 1)
  • a detector 33 is also arranged at each drum shock absorber 37 to detect when the reeling drum 4 gripped by the grab hook 36 and lifted by the lowering arm 32 has rolled along the roll surface 35 to the desired position before the lowering arm 32 returns to the primary system for receiving the reeling drum 4.
  • 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.
  • a central drive 100 for the reeling drum 4 is also arranged at the secondary system (see Figure 1) which means that the reeling drum 4 can be connected to a separate drive member via the opposite coupling device 11 of the reeling drum 4. Since this drive member is mounted on one of the secondary carriages 42, it is linearly displaceable together with these in a direction parallel to the rails 8.
  • a braking station 49 is also arranged at the downstream end of the reel-up 1 (see Figures 8 and 9), at which braking station 49 the paper reel 3 arrives when reeling has been completed and after the paper web 2 has been cut. In the braking station 49 the paper reel 3 is retarded to stand-still by a braking device 50 mounted at each stand part 6, 7.
  • 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 handling station 54 also comprises a device 60 for axial displacement of a reeling drum 4 (see Figure 11).
  • This drum moving device 60 is situated on the operator side of the reel-up, aligned with said lifting table 58, and comprises a longitudinally extending, horizontal support element 62 arranged at right angles to the machine direction and formed by two parallel U-shaped rails 63, the top surfaces 64 of which form sliding surfaces for the reeling drums 4. Between them the rails 63 define a space for receiving a carriage 67 slidingly journalled on the rails 63.
  • the carriage 67 supports a gripping member 66 for detachable connection to the opposing end portion of a reeling drum 4.
  • a motor 69 is mounted at the outer end part of the support element 62 to drive a cogged belt 70 rigidly connected to the carriage 67 to move the carriage to and fro in the support element 62.
  • 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.

  • 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 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 cutter is started. While a number of turns of the paper web 2 are wound onto the reeling drum 4, this is moved by the primary arms 38 along the periphery of the surface winding drum 9 down to the stand parts 6, 7 (see Figures 4, 5) where the gripping members of the secondary system take over control of the reeling drum 4 (see Figure 6).
  • the lowering arms 32 are thus free to pass the primary lowered reeling drum 4 to be turned up to the drum stock 15 ready to fetch the next reeling drum 4 when a signal therefor is given.
  • 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 machine operator causes the reeling drum 4 to expand, thereby firmly locking the cores 14 in the correct position for the cut web sections 52, 53 and the reeling drum 4 with its cores is then ready to be automatically transported up to the rails 21 of the drum stock 15 by the lifting device 84 at the downstream end of the reel-up 1.
  • the lifting arms 85 are thus in their lowermost position, to which they are lowered each time a reeling drum 4 with its cores has been lifted up.
  • 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 actuators 90 are once more activated and the reeling drum 4 lifted up to the entry 99 of the drum stock 15 where it rolls off the inner lifting arm parts 87 of the lifting arms 85, down onto the rails 21 (see Figures 11 and 17). The rolling movement is somewhat retarded by the shock absorbers 95.
  • the detectors 41 indicate that the reeling drum 4 has been transferred to the stock 15 and the lifting arms 85 are then swung back to their lowermost positions.
  • 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.
  • the reeling station of the reel-up may of course be designed in various known ways.
  • the reel-up has no primary system and has instead double secondary units movable linearly along the machine stand, said secondary units alternately with each other receiving the reeling drums directly from said lowering arms.
  • Each second unit then supports the reeling drum throughout the production phase from empty reeling drum to finished paper reel.
  • the secondary system may consist of only one pair of pivotable secondary arms.
  • lifting elements in the form of pivotable lifting arms 85 are preferable both from the design and the function aspect, taking into consideration the limited space available near the reel-up, they can be designed and arranged differently, e.g. as lifting bars movable up and down in vertical guides.
  • 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.
