Definitions

  • the present invention relates to a reel-up in a paper machine for manufacturing a paper web, reeled onto reeling drums to form paper reels, which reeling drums have bearing housings at their ends, which reel-up comprises
  • a primary system having a pair of pivotable primary arms with gripping devices to receive an empty reeling drum
  • a secondary system which receives the reeling drum from the primary system once an initial number of turns of the paper web have been wound onto the reeling drum.
  • the secondary system usually has either a pair of secondary arms or a pair of secondary carriages, which, as the diameter of the paper reel increases, are pivoted or linearly displaced, depending on the case, along a pair of mutually parallel stand members, on which a driven surface winding drum is rotatably arranged, over which the paper web runs.
  • the primary arms place the reeling drum to abut the surface winding drum to initiate reeling of the web. Thereafter, the primary arms convey the reeling drum along the surface winding drum down to two rails, along which the reeling drum, rotatably carried by its bearing housings, is displaced during the continued reeling of the web.
  • the linear load varies throughout the reeling-up operation in magnitude as well as direction and depends mainly on the three variables applied load, weight increase of the growing paper reel, and current location of the paper reel along the envelope surface of the surface winding drum.
  • the location relative to the surface winding drum causes the linear load to vary, as the paper reel is pressed against the envelope surface along a contact line, which is shifted downwards in an arc-shaped movement along the envelope surface, whereby a horizontal as well as a vertical force component arises, the magnitudes of which vary mutually throughout the entire movement.
  • the linear load is affected negatively also during the transfer of the reeling drum from the primary system to the secondary system, as an exchange must take place between the separate gripping members of the two systems and, with central drive, between two separate drive means as well, whereby a temporary increase in pressure arises.
  • the linear load must be kept within carefully determined maximum and minimum values throughout the entire reeling-up process.
  • US-3,614,011 describes a reel-up with two primary arms, which each have a loading device outside the reeling drum to regulate the applied load, which loading device comprises a power cylinder and a holding hook displaceable along the primary arm by means of the power cylinder.
  • Each loading device co-operates with an unloading device, comprising a lower, manoeuvrable cam track, arranged at each end of the surface winding drum of the reel-up.
  • the reeling drum is supported on the cam tracks and conveyed along the curved surfaces of the same down to a pair of rails, where two secondary arms assume control of the paper reel.
  • Each cam track is pivotable about a shaft by means of a power cylinder to be able to regulate the linear load to some extent while the paper reel is growing against the surface winding drum.
  • the linear load in the nip is thus regulated by the power cylinders of the loading devices, through the displacement of the locking hooks, as well as by the power cylinders of the unloading devices, through the adjustment of the cam tracks.
  • US-4,634,068 describes a reel-up, in which it is sought to control the variation of the linear load.
  • Each primary arm comprises a loading device with a power cylinder, which controls an upper locking hook displaceable along the primary arm, and an unloading device, arranged at the primary arm and having a lower support with an unloading cylinder, arranged to relieve the nip of the increasing weight of the paper reel.
  • the control of the linear load must be performed by two completely separate, but yet necessarily mutually co-operating, devices, of which the loading device alone regulates the applied load, while the unloading device regulates the unloading of the weight of the reeling drum and the increasing weight of the growing paper reel. This makes it very difficult to control the linear load in an optimal way.
  • a further problem with both these known reel-ups is that their primary arms have gripping devices with fixed or substantially fixed lower holders for the reeling drum.
  • the diameter of the paper reel can thus only be permitted to increase to a certain pre-determined maximum limit before the paper reel lifts the reeling drum from said lower holders.
  • the displaceable upper locking hook and the fixed lower holder or cam track have, in some reel-ups, been replaced by a gripping device with two pivotable gripping parts, consisting of an upper locking hook and a lower support arm, both being journalled to the primary arm about separate pivoting shafts.
  • the locking hook and support arm are pivoted out from the envelope surface of the surface winding drum.
  • the reeling drum is thereby undesirably rotated within the gripping device, which rotation is caused by the locking hook and support arm being displaced in parallel relative to the surface winding drum whilst simultaneously being pivoted about their respective pivoting shafts, journalled a distance from each other.
  • the object of the present invention is to provide an improved reel-up, which reduces the problems discussed above, at least to a considerable extent.
  • the reel-up in accordance with the invention, is characterized in that the inner locking arm is pivotably journalled about the same journalling shaft as the outer locking arm with the result that the outer locking arm, the inner locking arm and the first actuator constitute a pivotable unit arranged, when influenced by the second actuator, to be pivoted about the journalling shaft to regulate the linear load between the paper reel growing on the reeling drum and the support means.
  • the reel-up in accordance with the invention, has a primary system, which provides considerably improved control of the linear load between the surface winding drum and the growing paper reel, which means that the linear load can be regulated with greater precision than previously possible.
  • the actuator controlling the locking arms, so that it locks or fixes the gripping device in a locked position whilst maintaining the power applied for locking.
  • the function can be simply described as a "frozen" condition. This means that a possible leakage in the supply pipes to the actuator does not prejudice the fixed, locked position of the locking arms retaining the reeling drum.
  • Improved safety is achieved in that there is no risk of the reeling drum falling out of the gripping device under the influence of its own weight in the event of the above-mentioned fault arising.
  • a very safe transition can be achieved between the primary system and the secondary system so that the linear load can be maintained within the prescribed range even during this transition.

  • Figure 2 is a side view of the reel-up in accordance with Figure 1 and shows schematically one of the primary arms of the primary system with a gripping member in accordance with the invention in an open top position and with a paper reel being reeled in a secondary carriage.

  • FIG 1 the upstream part of a reel-up in a paper machine, in which paper is manufactured in a continuous web, is shown a perspective view.
  • the web 1 is reeled in the reel-up, as shown in Figure 2, on a rotatable reeling drum 2 to form a paper reel.
  • the reeling drum 2 has a bearing housing 4 arranged axially inside a braking drum 18 at each end, which bearing housing 4 is provided with a peripheral, surrounding groove 40, see Figure 7.
  • the braking drum 18 is usually provided with an axial coupling device.
  • the reel-up comprises a machine-stand with two lower, longitudinally extending stand parts 5 and two upper, longitudinally extending stand parts 7.
  • Rails 9, 10 are horizontally, rigidly mounted to these stand parts to support the reeling drums 2, which, carried in their bearing housings 4, roll along the rails 9, 10, the latter being received in the grooves 40 of the bearing housings 4.
  • a support means in the shape of a a surface winding drum 11 extends between the lower stand parts 5 and has shaft pins 12 for rotatable journalling of the surface winding drum 11 in bearing housings 13, mounted on the lower stand parts 5.
  • the paper web 1 runs about the envelope surface of the surface winding drum 11, and a drive device (not shown) is arranged to rotate the surface winding drum 11 with a peripheral speed that corresponds to the speed of the paper web 1.
  • a drive device (not shown) is arranged to rotate the surface winding drum 11 with a peripheral speed that corresponds to the speed of the paper web 1.
  • the distance between the rails 9 of the lower stand parts 5 is somewhat greater than the width of the web.
  • each bearing housing 13 has inner and outer end walls 14, 15 and a tubular, rotationally symmetrical casing 16, which is concentric with the shaft pin 12 and pivotably journalled in the bearing housing 13.
  • the axis of pivot of the casing 16 coincides with the axis of rotation of the surface winding drum 11.
  • the rails 10 of the upper stand parts 7 are arranged to support a stock of reeling drums 2.
  • the reel-up comprises two lowering arms 17, pivotably journalled on the machine-stand to be pivoted, by means of hydraulic cylinders 19, between an upper collecting position, see Figure 2, and a lower delivering position, see Figure 4.
  • the reel-up comprises a primary system and a secondary system to provide continuous reeling of the paper web 1 on a reeling drum 2.
  • the secondary system has two secondary carriages 20, each journalled to a respective lower stand part 5, to be linearly moved along the stand parts 5.
  • a hydraulic cylinder (not shown) is attached to each secondary carriage 20 and stand part 5 for reciprocating movement of the secondary carriage 20 along the stand part 5 in a controlled manner.
  • the movements of the secondary carriages 20 are synchronized with each other.
  • Each secondary carriage 20 has a gripping member, which comprises a locking arm 21 and a press arm 22 and is arranged to receive a reeling drum 2 with a commenced paper reel 3 and to remove the same when the paper reel is completed and, further to be closed around the bearing housings of the same to guide the reeling drum 2 along the rails 9 whilst maintaining the requisite linear load between the growing paper reel 3 and the surface winding drum 11.
  • the locking and press arms 21, 22 are pivotably journalled on the secondary carriages 20 and manipulated by hydraulic cylinders (not shown), comprised in the control system of the reel-up for control of the reeling-up process.
  • the free ends of the locking and press arms 21, 22 carry small, rotatably journalled pulleys for co-operation with the bearing housings 4 of the reeling drum so that these are free to roll along the rails 9.
  • the reference number 23 denotes a position indicator of inductive type in the control system provided on each press arm 22 to detect a stop position for the respective secondary carriage 20, as the latter must stop, during the returning movement, a certain distance before the press arm 22 contacts the bearing housing 4 of the reeling drum 2, see Figure 6.
  • the primary system comprises two primary arms 24, pivotably journalled to pivot about the axis of rotation of the surface winding drum 11 in that the primary arms 24 are rigidly mounted, by welding, for instance, to the tubular, pivotably journalled casings 16 of the bearing housings 13 of the surface winding drum 11.
  • Each primary arm 24 has a waist part 25, by means of which the primary arm 24 is rigidly connected to the respective bearing housing 13 of the surface winding drum 11, a lower mounting part 26 and an upper mounting part 27, which two mounting parts 26, 27 are located on either side of the axis of rotation of the surface winding drum 11.
  • a hydraulic cylinder 28 is, via its piston-rod 29, pivotably mounted to the lower mounting part 26 of the primary arm 24 and, via the end of its cylinder 30, pivotably mounted to the respective lower stand part 5.
  • a horizontal synchronization shaft 31 extends between and through the lower stand parts 5, on which it is pivotably journalled.
  • Two connecting arms 32 are rigidly connected to the synchronization shaft 31 at both its ends and are pivotably connected to the primary arms 24 at their lower mounting parts 26. The movements of the primary arms 24 about their axis of pivot are thus synchronized with each other.
  • Each primary arm 24 comprises a tongs-like gripping member 33, comprising a first, outer locking arm 34 and a second, inner locking arm 35.
  • the expression “outer” and “inner” refer to positions in relation to each other and to the surface winding drum 11.
  • the outer locking arm 34 is pivotably journalled on the upper mounting part 27 of the primary arm 24 by means of a horizontal journalling shaft 36.
  • the inner locking arm 35 is pivotably journalled on the same journalling shaft 36 as the outer locking arm 34.
  • the outer locking arm 34 comprises a waist part 37, with which it is pivotably journalled on said journalling shaft 36, a free gripping part 38 for contacting the reeling drum 2 and a mounting part 39.
  • the gripping part 38 is in the shape of a hook, which in the locked position surrounds the bearing housing 4 of the reeling drum 2 with a certain sector angle, for instance about 90°.
  • the hook 38 and the mounting part 39 are located on either side of said journalling shaft 36.
  • the inner locking arm 35 likewise, comprises a waist part 41, with which it is pivotably journalled on said common journalling shaft 36, a free gripping part 42 for contacting the reeling drum 2 and a mounting part 43.
  • the free gripping part 42 which acts as a counter-support for the reeling drum 2 and the hook 38 in its locked position, and the mounting part 43 are located on either side of said common journalling shaft 36.
  • the gripping member 33 of the primary arm 24 comprises a first double-acting hydraulic cylinder 44 and a second double-acting hydraulic cylinder 45.
  • the first hydraulic cylinder 44 is, via its piston-rod 46, pivotably mounted to the mounting part 39 of the outer locking arm 34 by means of a shaft pin 47 and, via its cylinder 48, at the end of the cylinder 48 facing the piston-rod 46, pivotably mounted to the mounting part 43 of the inner locking arm 35 by means of two opposite shaft pins 49.
  • a symbolically indicated, flexible pipe 50 for supplying hydraulic oil to and evacuating it from said first hydraulic cylinder 44 is provided with a valve 51, which in practice is mounted on the hydraulic cylinder 44, for disconnecting said supply when the hydraulic cylinder is in a certain protruding position.
  • the first hydraulic cylinder 44 extends freely with its cylinder 48 upstream of and along the upper mounting part 27 of the primary arm 24, i.e. it has solely mechanical, pivotable contact with the inner locking arm 35, which thus carries the hydraulic cylinder 44.
  • Said second hydraulic cylinder 45 is, via its piston-rod 52, pivotably mounted to the gripping part 42 of the inner locking arm 35 by means of a shaft pin 53, located at a pre-determined distance from the journalling shaft 36 of the gripping member, i.e. the common journalling shaft of the locking arms 34, 35, and, via its cylinder 54, at its end facing away from the piston-rod 52, pivotably mounted to the upper mounting part 27 of the primary arm 24 by means of a shaft pin 55.
  • the hook 38 of the outer locking arm 34 has a surface 60 that is inwardly-curved or angled towards the drum-contacting gripping part 42 of the inner locking arm 35 in such a way that the distance between the free ends of the locking arms 34, 35 facing each other, when the gripping member 33 is in its active, locked position, is smaller than the diameter of the bearing housing 4 of the reeling drum 2 so that the reeling drum 2 is retained by the gripping member 33, even when it is facing downwards with its said free ends.
  • each bearing housing 13 is extended upwards to carry a support 56 with an upper surface for receiving the reeling drum from the lowering arms 17, with the supports 56 being positioned inside the grooves 40 of the bearing housings 4.
  • Each support 56 has a rearward stop 57, arranged to prevent the reeling drum 2 from rolling backwards when- delivered.
  • the supports 56 are located at such a level above the surface winding drum 11 that they carry the entire weight of the reeling drum 2 without loading the inner locking arms 35 and their hydraulic cylinders 45, although the locking arms 34, 35 are in contact with the bearing housings 4 of the reeling drum during this concluding phase of the lowering operation.
  • the outer locking arm 34 of each gripping member 33 is constructed out of two parallel plates 58, arranged a certain distance from each other for co-operation with the bearing housings 4 of the reeling drum 2 on either side of its groove 40.
  • the plates 58 are held rigidly in position by means of an intermediate part 59.
  • the two locking arms 34, 35 of the gripping member 33 form a pivotable unit, which is pivotable about the journalling shaft 36 by means of the second hydraulic cylinder 45, which thus forms part of the system for controlling the linear load between the initially growing paper reel 3 and the surface winding drum 11.
  • the pivotable unit also includes the first hydraulic cylinder 44.
  • the reel-up described above operates substantially as follows.
  • the primary arms 24 are in their top positions and their gripping members 33 are in their open positions for receiving an empty reeling drum 2, which is collected by the lowering arms 17 and placed on the two supports 56, see Figure 7, whereupon the first hydraulic cylinders 44 are activated to pivot the outer locking arms 34 downwards to abut the bearing housings 4 of the reeling drum 2 so that said bearing housings are securely clamped between the outer and inner locking arms 34, 35, as shown in Figure 4.
  • the valves 51 are activated so that the oil supply pipes 50 are closed and the outer and inner locking arms 34, 35 are fixed in relation to each other by each piston-rod 46 being held securely locked in its protruding position.
  • each gripping member 33 and its hydraulic cylinder 44 form a pivotable unit, pivotable about the journalling shaft 36 by activation of the second hydraulic cylinder 45.
  • a paper reel 3 has been completed in the secondary system.
  • the empty reeling drum 2 in the primary system is caused to rotate by means of said starting device not shown.
  • the hydraulic cylinders 28 of the primary arms 24 are activated to pivot the primary arms 24 to the rail position, as shown in Figure 5.
  • the reeling drum 2 at this stage already rotating, is moved to abut the surface winding drum 11, whereby the paper web 1 is brought into contact with the reeling drum 2 for wrapping and initiation of the reeling up.
  • the paper web 1 is torn and the secondary carriages 20 are activated to transport the completed paper reel 3 away from the surface winding drum 11, as also shown in Figure 5.
  • the weight of the reeling drum 2 and the turns of the paper web 1 Wound onto it have an effect on the linear load, from maximum influence in said initial angle position to no influence at all in the rail position in accordance with Figure 5.
  • the second hydraulic cylinders 45 will initially unload the surface winding drum 11 from the influence of part of the weight of the reeling drum 2, which unloading effect gradually diminishes as said influence diminishes.
  • the hydraulic cylinders 45 switch from a controlled, unloading function to a controlled, loading function, so that the reeling drum 2 will press against the surface winding drum 11 with gradually increasing force, depending on the angle position, to maintain the pre-determined linear load.
  • the inner hydraulic cylinder 45 also compensates for the continuous increase in diameter of the paper reel 3, which occurs while the reeling drum 2 is pivoted down to the rail position by the primary arms 24, by synchronously pivoting the two units and the reeling drum 2 held by said units, although still rotatable, so that the distance between the axis of rotation of the reeling drum 2 and the axis of rotation of the surface winding drum 11 increases.
  • the angle positions of the primary arms 24 relative to a defined starting position are suitably sensed by a position detector in one of the hydraulic cylinders 28 of the primary arms 24. After recalculation, this provides a more precise value for the angle position than an angle indicator which measures the angle position of the primary arm directly during its pivoting movement.
  • control system of the reel-up can be pre-programmed with a curve chart relating to the value of the vertical force component as a function of the angle positron in relation to the surface winding drum 11.
  • the gripping members 33 of the primary arms 24 retain the reeling drum 2 in its two bearing housings 4, the latter cannot rotate. Consequently, the bearing housings 4 cannot, in their locked position, be brought into direct contact with the rails 9, if friction is to be avoided.
  • the downward pivoting movement of the primary arms 24 must therefore be halted before the bearing housings 4 contact the rails 9. Such a halt occurs when the distance between each bearing housing 4 and rail 9 is one or a few millimetres.
  • the hooks 38 of the outer locking arms 34 encompass the bearing housings 4 from below when the gripping members 33 are in the rail position, which means that the hooks 38 carry a substantial part of the weight of the reeling drum 2 in this rail position.
  • the reeling-up process continues with a controlled linear load when the primary arms 24 are in this position until the secondary carriages 20 take control of the reeling-up operation.
  • the returning movement of the secondary carriages 20 towards the surface winding drum 11 is halted by the position indicators 23 a certain distance before the press arms 22 of the secondary carriages 20 reach the bearing housings 4, thus preventing an instantaneous increase in the linear load, more precisely a doubling, which would occur if the gripping members of the secondary carriages 20 were to continue in the direction towards the bearing housings 4 to take control of the linear load directly.
  • the paper reel 3 is allowed to "grow into" the system for control of the linear load of the secondary carriages 20, i.e.
  • the diameter of the paper reel 3 continues to increase whilst the linear load is controlled by the primary system until the bearing housings 4 of the reeling drum 2 with the growing paper reel 3 meet the press arms 22 of the secondary system, as illustrated in Figure 6.
  • a smooth transition from the primary to the secondary loading system is thus achieved.
  • the inner surfaces of the hooks 38, which surfaces contact the bearing housings, are angled and incline obliquely downwards, towards the rails 9, and, when the gripping members 33 are opened by the valves 51 being opened and the first hydraulic cylinders 44 activated, the reeling drum 2 is lowered relatively slowly towards the rails 9, in that the bearing housings 4 follow the tilted surfaces 60 of the hooks 38 in a vertical movement, correspondingly slow relative to the opening movement of the outer locking arms 34.
  • the second hydraulic cylinders 45 are of a low-friction type to achieve the greatest possible sensibility in the control of the linear load.
  • Secondary arms can be used instead of secondary carriages 20.
  • Pneumatic cylinders or, if possible, other types of actuators can be substituted for the hydraulic cylinders described above, if so desired.
  • indicators are arranged in a plurality of other locations in the reel-up to detect different positions for other movable structural elements to obtain data for controlling the reeling-up process during desired phases.
  • the axis of pivot of the primary arms 24 is co-axial with the axis of rotation of the surface winding drum 11. If so desired, however, the axis of pivot of the primary arms can be eccentrically arranged in relation to the axis of rotation of the surface winding drum.
  • the gripping part 38 of the outer locking arm 34 is shaped as a hook, while the contact surface of the gripping part 42 of the inner locking arm 35 has a more straight or slightly inwardly-curved shape.
  • the invention can also be applied to a reel-up, the secondary system of which has at least one secondary unit with two secondary bodies that are journalled on the stand parts for linear movement and have lifting devices for lifting the reeling drum up from the stand rails and supporting the reeling drum during the reeling-up of the paper web.
  • the invention can further be applied to a reel-up with twin secondary units lacking the above-mentioned lifting devices.
  • the support means consists of a surface winding drum. In an alternative embodiment (not shown), the support means consists of a belt or of a combination of surface winding drum and belt.
