Description

Technical Field

[0001] The present invention generally relates to the production of fibrous webs and to a reel-up-unwinder system for the winding and unwinding of master rolls for a fibrous web production line. In particular, the present invention relates to components for manipulating the reels. The present invention also particularly relates to a reel-up-unwinder system for a fibrous web production line. Background Art

[0002] It is known that fibrous webs, such as paper webs and cardboard webs, are made in the installations and machines that together form a fibrous web production line, which can be several hundred meters long. As is known from the prior art, a fibrous web production line typically comprises a component formed by a plurality of installations and machines arranged in succession in a processing line. A typical production line for fibrous webs includes a forming section, which includes a headbox and a wire section; a pressing section; a drying section; and a reel-up. The production line may also include other sections and installations for processing and / or finishing the fibrous web, such as a sizing machine, a coating device, a calender. The production and processing line generally also includes at least one slitter-winder for forming customer rolls and a roll packaging device. At present, the operating speeds of fibrous web production lines (especially for certain fibrous web grades, such as for fluting webs and liner webs grades) are very high, such that two slitter-winders are required to slit and wind the fibrous webs produced in the fibrous web production line.

[0003] In a fiber web production line, the production of the fiber web is carried out as a continuous process. The fiber web completed on the fiber web production line is wound by a winder around a winding shaft (i.e., a reel) into a master roll with a diameter that can be greater than 5 meters and a weight greater than 160 tons. The purpose of winding is to change the fiber web, which is manufactured flat and continuously, into a form that is easier to process. At the winder located in the main fiber web production line, the continuous process of the fiber web production line is interrupted for the first time and becomes a periodic operation. Thus, the winder is used in the production of the fiber web to wind the fiber web from the fiber web production line into a master roll, which can be conveyed for further processing, but the winder is also used to wind the fiber web from a coater, a calender, or a corresponding finishing device. In the winder of the fiber web, the continuous fiber web delivered from the previous section of the fiber web production line, from an off-line coating section, or from a corresponding fiber web processing device is wound around a reel (winding shaft) to form a master roll. The fiber web is brought onto the master roll via a reeling cylinder, which is arranged to be rotatable, and the master roll is pressed against the reeling cylinder by means of a loading device, which is arranged to be connected to the reel or to the reeling cylinder. Thus, the fiber web enters the master roll and is thereby pressed between the previous layer of the master roll and the covering surface of the reeling cylinder, i.e., in the winding nip.

[0004] The fiber web wound onto the master roll in the winder is full-width, and thus must be cut in the longitudinal direction into partial webs of a suitable width, and the partial webs are wound into partial fiber web rolls (customer rolls) with a suitable fiber web length and / or with a diameter suitable for customer use. The slitting and winding are carried out in a suitable separate machine as known in the prior art, i.e., in a slitter rewinder. The slitter rewinder includes: an unwinder in which the master roll is unwound; a slitting section in which the fiber web unwound from the master roll is slit, i.e., cut in the longitudinal direction into partial webs of a desired width; and a winding section for winding the customer rolls. When the customer rolls are completed, the slitter rewinder stops, and a plurality of wound rolls, i.e., so-called groups, are removed from the winder. Then, the process continues with the winding of a new group. These so-called group change steps are periodically repeated in sequence until the paper of the master roll is used up, thereby performing a master roll change, and the operation starts again with the unwinding of a new master roll. Then the empty reel is returned to the winder. Before the previous winding shaft is full, i.e., when the master roll is ready for roll change, the winder must be provided with an empty winding shaft. Usually, a plurality of empty reels are stored in a so-called reel storage section. There is a cycle of reels between the winder and the unwinder, in which the master roll together with the reel is conveyed to the unwinder, and the empty reel is returned from the unwinder to the winder. A corresponding reel cycle can also be located, for example, between the fiber web production and an off-line coater or other fiber web finishing machines.

[0005] A storage device for winding rolls is disclosed in Japanese Patent Application Publication H0395003A, which includes: a transport carriage that can be attached to the outside of the roll storage position; a storage device having a pair of left and right paired columns and at least two or more steps starting from the bottom, the intervals of which correspond to the interval between the two ends of the winding core; a support arm having a holding arm that engages with and holds the two ends of the winding core of the winding roll; a lift frame having a pair of left and right conveying arms that respectively support the ends of the winding core in the downward direction; a lifting frame that is provided above the winding roll storage position and above the winding roll conveying space on its side; a traveling beam that moves in the front-rear direction; and a lifting frame that suspends the lift frame.

[0006] A movable storage device is disclosed in WO Patent Application Publication 2010097515A1, which is supported on the floor and movable between at least two target stations for receiving, moving, and manipulating rolls, winding shafts, and / or machine reels intended to manipulate a fiber web, and the movable storage device includes a receiving member for receiving the load being manipulated and holding the load at its two support ends; the movable storage device includes at least one vertical support member that is supported on the floor for supporting the receiving member at a fixed height or in a height-adjustable manner and for holding the load such that during operation, the movable storage device and at least one roll, winding shaft, and / or machine reel being manipulated are movably supported on the floor by means of at least one vertical support member above the fiber web manufacturing device and / or finishing device.

[0007] A component for manipulating a reel and a winding / unwinding device for a fibrous web machine are disclosed in EP Patent Application Publication No. 4124597 A1. The known component for manipulating a reel includes: a linear support track having a first end and a second end arranged parallel to each other; a reel carriage including a transverse bridging member arranged on the support track. In this component, the support tracks are arranged at a first distance from each other, and the first distance is greater than the axial length of the reel. The carriage of the component is provided with a lifting device configured to vertically lift the highest point of the reel from below at least one of the support tracks to at least partially above at least one of the support tracks, and at its two ends, there are flat supports for the reel, wherein the flat supports are provided with a drive, and after the reel has been lifted to a vertical position above the flat supports, the flat supports can be moved under the bearing housing of the reel by means of the drive. A winding / unwinding device for a fibrous web machine is disclosed in this publication, and the winding / unwinding device includes: a winding station located at the first end of the device, the winding station being configured to produce a master roll from a web running on a reel supported by a bearing housing at its end; and an unwinding station located at the second end of the device, the unwinding station being configured to controllably unwind the web from the master roll produced in the winding station, and the device includes a component for manipulating the reel, the component being configured to operate between the winding station and the unwinding station and further being configured to return an empty reel from the unwinding station to the winding station. The device includes parallel transfer tracks located between the winding station and the unwinding station, the parallel transfer tracks being for transferring the master roll from the winding station to the unwinding station, and the transfer tracks are arranged at a second distance from each other, and the second distance is less than the first distance between the support tracks of the component for manipulating the reel. The support tracks are arranged vertically above the transfer tracks. In the known component for manipulating a reel and the winding machine, due to the crane being arranged in the reel carriage, especially considering the power arrangement for the movement of the crane and the carriage and considering the space requirements, the configuration of the component is quite complex. Additionally, since the crane and the reel carriage are combined, their operating functions are quite limited because they cannot be used separately.

[0008] The object of the present invention is to create a component for manipulating a reel in which the disadvantages of the prior art are eliminated or at least minimized.

[0009] Another object of the present invention is to create a winding / unwinding machine system in which the disadvantages of the prior art are eliminated or at least minimized. Summary of the Invention

[0018] According to an advantageous feature of the present invention, the reel conveying device comprises an integrated rotating device for waste removal, i.e., an integrated rotating device for removing so-called bottom waste paper that may remain around the reel after unwinding.

[0019] According to an advantageous feature of the present invention, in this component, the reel conveying device comprises a lateral direction support beam extending between the support portions of the reel conveying device, and the lateral direction support beam is arranged in the middle region of the reel conveying device, preferably only arranged in the middle region of the reel conveying device, i.e., the middle region as observed from the side.

[0020] According to an advantageous feature of the present invention, the distance between the support rails of the component for manipulating the reel is longer than the length of the reel, preferably at least 500 mm longer.

[0021] According to an advantageous feature of the invention, the reel transfer device comprises a moving element and a body part movably supported on the moving element, the moving element being supported on a support rail.

[0022] According to an advantageous feature of the invention, the reel transfer device comprises: a support part, which is preferably provided with a notch for receiving and supporting, preferably at a bearing in the end of the reel, the end; and a support arm connecting the support part of the reel transfer device to the body part.

[0023] According to an advantageous feature of the invention, the reel transfer device is configured as a one-piece unit.

[0024] According to the invention, the lifting device is movably arranged in the vertical direction relative to a vertical support element at one end of the support rail, and the lowering device is movably arranged in the vertical direction relative to a vertical support element at the other end of the support rail.

Further, the construction of the reel transfer device is simple. Additionally, the reel transfer device can be used to support a waste removal station on a track. This also provides increased production capacity since, during the removal of waste from one reel in the reel transfer device, another reel can already be lifted by the lifting device. Further, additional storage positions are provided for the reels since one reel can be located in the lifting device, one reel can be located in the reel transfer device, and, if needed, one reel can also be located in the lowering device. This enables the reel station to be configured with fewer positions for the reels and / or the reel storage can be configured with fewer positions for the reels, which in turn reduces the space required for the assembly and the construction cost of the assembly. Even one additional storage position for the reels provides greater flexibility in the operation of the coiler - uncoiler system. The positioning of the vertical support elements such that their positions are in the regions of the respective ends of the reel provides that the reel can be picked up directly from the uncoiler without additional transfer movement, which also ensures that any waste fiber web on the reel is not unwound at this point. The lifting device and the lowering device provide a simplified structure and cost savings in production as well as in spare parts. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description

[0041] In the following description, unless otherwise specified, the same reference numerals denote similar components, and it should be understood that these examples are easily modified to adapt to different uses and conditions within the framework of the present invention. For clarity reasons, some repetitions of reference numerals may be omitted in the drawings.

[0042] At Figures 1A - 4F An example of a component 50 for manipulating a reel 55 in a coiler-uncoiler system 10 is schematically shown. Figures 5A - 6 The example shown in Figures 1A - 4F corresponds to the example shown in

[0043] and further includes a storage system 60 for the reel 55. The coiler-uncoiler system 10 includes a coiler RU and an uncoiler UW, as well as a reel station RS and a master roll storage section PRS. The coiler-uncoiler system 10 may further include a waste removal station RUS. The waste can be removed to the shredder of the uncoiler UW or the shredder of the master roll storage section PRS or the shredder of the coiler RU. AtFigures 4A - 4F The positions of the winder RU, unwinder UW, reel station RS and waste removal station RUS of the winder-unwinder system 10 are shown very schematically in. As Figures 5A - 6 shown in the example of, the winder-unwinder system 10 may also include a reel storage 60.

[0044] The reel station RS, winder RU, master roll storage PRS and unwinder UW are constructed along parallel transfer tracks 11 that are horizontal or slightly inclined towards the unwinder UW and extend in the machine direction. The transfer tracks 11 are arranged at spaced horizontal heights. Bearings 52 at each end 51 of the reel 55 are respectively arranged on supports of the transfer tracks 11 at each end of the reel 55. In the operation of the winder-unwinder system 10, first the reel 55 is transferred along the transfer tracks 11 from the reel station RS to the winder RU, in which the fiber web is wound around the reel 55 to form a master roll 100. The completed master roll 100 moves along the transfer tracks 11 to the master roll storage PRS, from which the master roll 100 moves along the transfer tracks 11 to the unwinder UW to unwind the fiber web from the master roll 100 for further processing of the fiber web. These sequences are continuously repeated as long as there is an incoming fiber web to be wound and / or a fiber web to be unwound. It should be noted that, as is known, the operating sequence of the winder-unwinder system 10 at least partially provides for the continuous operation of the winder-unwinder system 10 simultaneously.

[0045] The winder-unwinder system 10 also includes a component 50 for manipulating the reel 55, in which vertical support elements 13, 15 are positioned such that their positions are in the regions of the respective ends of the reel 55, so that the reel 55 can be picked up directly from the unwinder without additional transfer movement, which also ensures that possible waste fiber webs on the reel 55 are not unwound. Parallel support tracks 12 extending in the machine direction are positioned between the vertical support elements 13, 15. In addition to the vertical support elements 13, 15, additional vertical supports 14 may be positioned to support the support tracks 12. In the winder-unwinder system, the support tracks 12 are positioned above the transfer tracks 11, preferably above the highest point of the master roll 100 supported on the transfer tracks 11. The distance between the parallel support tracks 12 is preferably greater than the distance between the parallel transfer tracks 11. This enables, for example, a ceiling-mounted crane or a similar lifting device to be used to lift the master roll 100 from the transfer tracks 11. The distance between the support tracks 12 is longer than the length of the reel 55, preferably at least 500 mm longer. This enables the full master roll 100 to be lifted from the transfer tracks 11 when needed.

[0046] Accordingly, the assembly 50 for manipulating the reel 55 includes two support rails 12 that extend apart from each other in a horizontal lateral direction and extend between corresponding vertical support elements 13, 15. Two vertical support elements 13 (i.e., the first vertical support element 13) are located at one end of the assembly 50 and are configured to provide support to a vertically movable lifting device 30 that is configured to lift the reel 55 from the unwinder UW to the support rails 12. The lifting device 30 is positioned in the vertical region between the support rails 12. The reel 55 is conveyed along the support rails 12 from the first end of the support rails 12 to the second end of the support rails 12, i.e., to the other end of the assembly 50, which is provided with two additional vertical support elements 15 (i.e., the second vertical support element 15), and the second vertical support element is configured to provide support to a lowering device 70 that is configured to lower the reel from the support rails 12 to the reel station RS. The support rails 12 may include a waste removal station RUS in which, for example, by unwinding, a possible waste fiber web around the reel 55, so-called bottom broke, is removed. The reel conveying device 40 advantageously includes an integrated rotating device 47 for removing the waste fiber web, i.e., the bottom broke. The support rails 12 may also include a reel storage 60 located at the second end of the support rails 12, in which case the reel 55 is conveyed from the reel conveying device 40 to the reel storage 60, and the lowering device 70 lowers the reel 55 from the reel storage to the reel station RS to provide to a winder RU for winding the master roll 100.

[0047] It should be noted that even though it may be described only for one end of the reel 55, the assembly 50 includes similar structural components for each end of the reel 55.

[0048] It should also be noted that after being received from the unwinder, the reel 55 may include a waste fiber web around it. The waste fiber web can be removed at the waste removal station RUS on the support rails 12, so that when the reel 55 is conveyed to the reel storage 60 / reel station RS and further conveyed to the winder RU, there is no fiber web on it.

[0049] In Figures 1A - 1F the operating steps of the assembly 50 for manipulating the reel 55 are schematically shown. In Figure 1AIn the stage shown, the lifting device 30 is in its lower position and is used to receive the reel 55 from the unwinder after the unwinding of the mother roll is completed and the fiber web is cut. The respective end portions 51 of the reel 55 are received by the respective hook members 32 of the respective lifting devices 30. The end portions 51 are the axial end portions of the reel including the bearings 52, that is, the longitudinal end regions of the reel, which are located outside the longitudinal region onto which the fiber web is to be wound. The lifting device 30 moves the sliding support 31 upward along the vertical support element 13. In the uppermost position, the lifting device is located above the support rail 12, positioning the reel 55 above the height of the reel transfer device so that the reel transfer device 40 can move under the reel 55 to receive the reel 55. In Figure 1B In the stage, the reel transfer device 40 is moving towards the first end of the support rail 12. In Figure 1C In, the lifting device 30 lowers the reel 55 towards the reel transfer device 40, and as Figure 1E shown, the hook members 32 of the lifting device are separated and the reel 55 is transferred to the reel transfer device 40. In Figure 1F In the stage shown, the reel transfer device 40 starts to move the reel 55 along the support rail 12 towards the other end of the support rail 12, and the lifting device 30 is ready to return downward to pick up the next reel 55.

[0050] In Figures 2A - 2B In, as an end view in the transverse direction, the assembly 50 for manipulating the reel 55 in the winder-unwinder system 10 is shown. In Figure 2A is viewed from the middle of the system. In Figure 2B is viewed from the winder end or the unwinder end of the system. As can be seen from the side view, the reel transfer device 40 is further supported in the middle region (preferably only in the middle region) by a transverse support beam 46 that extends between the two support portions 45 of the reel transfer device 40.

[0051] As can be seen from the drawings, especially in Figures 3A - 3BAs can be seen in more detail, the lifting device 30 includes a hook member 32 for receiving the respective end 51 of the reel 55. The hook member 32 extends in the machine direction. The hook member 32 is positioned on the end 51 of the reel 55 at a certain distance from the outermost surface of the end 51 of the reel 55. The lifting device 30 further includes a sliding support 31 configured to slide along a respective sliding surface of the vertical support element 13. The reel transfer device 40 includes a body portion 41 movably supported on moving elements 42, 43 (such as wheels 42, 43) on the support rail 12. The reel transfer device 40 is constructed as an integral piece. The body portion 41 is connected to the support portion 45 by a support arm 44. The support arm 44 enables the support rail 12 to be positioned outside the length of the reel 55 in the transverse direction. Thus, if needed, the mother roll 100 and / or the reel 55 on the transfer rail 11 can be obtained, for example, by a crane or a separate hoist for operation. The end 51 of the reel 55 is provided with a bearing 52, and the support portion 45 is preferably positioned to this bearing to provide stable support. In Figure 3A In, the end 51 of the reel 55 is in the support of the hook member 32 of the lifting device 30, and in Figure 3B In, the bearing 52 of the end 51 of the reel 55 is in the support of the support portion 45 of the reel transfer device 40. The hook member 32 of the lifting device 30 preferably has an inclination mechanism 33 which is used to lower the lifting device 30 even when there is a reel 55 occupying the unwinder UW. The lowering device 70 is advantageously constructed like the lifting device 30 and is thus provided with corresponding structural components, and the operation of the lowering device 70 is only opposite to that of the lifting device. Thus, in the lifting device 30 and the lowering device 70, the hook members 32 extend towards each other. The inclination mechanism 33 is advantageous in the lifting device 30 but can also be constructed in the lowering device 70 to provide a moving space. In Figure 7 In, the hook member 32 is shown in an inclined position.

[0052] In Figures 4A - 4F In, as a side view in the machine direction, the assembly 50 for manipulating the reel 55 in the winder-unwinder system 10 is shown. In Figure 4A In the stage of, the lifting device 30 is picking up the reel 55 from the unwinder and is ready to lift the reel 55 upwards to convey it to the reel transfer device 40. In Figure 4B In the stage of, the reel 55 is conveyed in the reel transfer device 40 along the support rail 12 towards the end with the reel station RS. In Figure 4C In the stage of, the reel 55 is conveyed to the end with the reel station RS, and in Figure 4D In the stage of, the reel is transferred from the reel transfer device 40 to the lowering device 70. In Figure 4EIn the phase where the reel 55 is lowered to the reel station RS in the lowering device 70, in Figure 4F In the phase where the reel 55 has been conveyed, the lowering device has moved upward and is ready to receive the next reel, and the reel conveyor 40 has returned toward the end of the lifting device 30 located in the upper position.

[0053] In Figures 5A - 5D As a side view in the machine direction of the coiler end of the system, a coiler-uncoiler system 10 with a reel storage section 60 is shown. The reel storage section 60 is supported on the support rail 12 at this end of the support rail 12. The reel storage section 60 can be slightly inclined toward the conveying end where the lowering device 70 picks up the reel 55. The reel storage section 60 is supported by the vertical support beam 16. The operation of the assembly 50 for manipulating the reel 55 corresponds to the above operation, but instead of conveying the reel 55 to the lowering device 70, the reel conveyor 40 conveys the reel 55 to the reel storage section 60. As described above, the lowering device 70 picks up the reel from the reel storage section 60 and conveys it to the reel station RS. In Figure 5A In the phase where the reel conveyor 40 is conveying the reel 55 toward the reel storage section 60 where three reels 55 are stored. In Figure 5B In the phase where the reel conveyor 40 is ready to convey the reel 55 to the reel storage section 60, and the lowering device 70 is taking out the next reel 55 in sequence from the reel storage section 60. In Figure 5C In the phase where the next reel 55 in sequence has been conveyed to the lowering device 70, and there is space in the reel storage section 60 for conveying the reel 55 from the reel conveyor 40 to the reel storage section 60. In Figure 5D In the phase where the reel conveyor 40 has conveyed the reel 55 to the reel storage section 60.

[0054] In addition, the assembly 50 provides an additional storage location because one reel 55 can be located in the reel conveyor 40 while one reel is in the lifting device 30.

[0055] In Figure 6 As a side view in the machine direction, the assembly 50 for manipulating the reel 55 with the reel storage section 60 in the coiler-uncoiler system 10 is shown in the phase described above in conjunction with Figure 5A description.

[0056] In Figure 7In FIG. 0, a side view in the machine direction of the unwinder end of the system 10 shows the assembly 50 for manipulating the reel 55 in the winder-unwinder system 10, where the hook member 32 of the lifting device 30 of the assembly 50 is in an inclined position, which allows the lifting device 30 to be lowered even when a reel 55 occupies the unwinder UW.

[0057] In view of the above, the assembly 50 has a lifting device 30 for lifting the reel 55 from the unwinder UW and a lowering device of a similar construction for conveying the reel 55 to the reel station RS for the winder RU. The lifting device 30 has a hook member 32 for lifting the reel 55 from the unwinder UW. The hook member 32 lifts the reel 55 from the reel end 51, which prevents the possible bottom fiber web (i.e., the possible waste fiber web) on the reel 55 from being unwound. The sliding support 31 of the lifting device 30 raises the reel 55 high enough so that the reel transfer device 40 can pass over the end of the reel 55. The reel transfer device 40 has a support portion 45, which is preferably provided with a notch for supporting and carrying the reel 55. The lifting device 30 lowers the reel 55 into the support portion 45 in the reel transfer device 40 and lowers it low enough so that the reel transfer device 40 can freely move horizontally away from the lifting device. The reel transfer device 40 moves to the other end of the horizontal support rail 12, and the reel 55 is supported in the support portion 45, preferably in the notch. At the other end of the horizontal support rail 12, the process is carried out in the reverse order, so that the hook member 32 of the lowering device 70 is located below the end 51 of the reel 55 and between the reel transfer device 40 and the outermost end of the end 51 of the reel 55. The reel transfer device 40 moves away from the lowering device 70, and the lowering of the reel 55 can be carried out.
