    WINDER FOR WINDING A FIBER FIBER web The invention relates to a winder (reel) for winding (winding) a fibrous web. In particular, the invention relates to a winder according to the preamble of claim 1.
    As is known from the prior art, fibrous web production processes usually have an assembly which is formed by a number of devices which are arranged in succession in the process line. A conventional production and treatment line has a headbox, a wire section and a press section, as well as a subsequent dryer section and a winder. The manufacturing and treatment line may further include other lots and devices for finishing the fibrous web, e.g. a glue applicator, a coating device, a calender. The production and treatment line also has at least one roll cutting machine for forming customer-specific rolls and a roll packing device. And as is also known, fibrous webs such as Paper or cardboard webs are produced in machines that together form a fibrous web production line that can be several hundred meters long.
    In fibrous web production lines, production is operated as a continuous process. The finished fibrous web, which is output from the machine, is wound around a winding shaft with a winder, i.e. a winding core, wound into a reel (a machine reel), the diameter of which can be larger than 5 meters and the weight of which can be more than 160 tons. The purpose of winding is to bring the fibrous web from its flat production form to a form in which it can be handled more easily. With the winder, the continuous process of the machine is interrupted for the first time, after which the process is continued in stages. Every attempt is made to couple these stages as evenly as possible. The winder typically has a winding cylinder and two pairs of trolleys (racks) or two pairs of forks or a pair of trolleys (racks) and a pair of forks, with a rack / fork for each end of the winding core / spool for movement and support of the winding core and the reel to be wound. The web is wound around the winding core into a spool by means of a winding nip between the winding cylinder and the spool during winding, the winding taking place in a primary stage in a primary position and in a secondary stage in a secondary position.
    The nip load (nip load) is generated between the reel and the winding cylinder and it is provided by loading the winding core through the primary frames / forks or through the secondary frames / forks against the winding cylinders. In winders where the required nip load is provided, the force required is concentrated on a fairly small area of the winding core. In most prior art arrangements, the winding core rotates during winding on the guides that are supported by its rotary bearing housing.
    In winders, the support frames, transport trolleys and forks have a fastening / locking mechanism for the winding shaft, so that the winding core remains on the frames and / or forks in all winding stages. Different types of locking and loading devices (loading devices) are used for winding frames or winding forks.
    On a winder, a certain amount of a fibrous web is wound around the winding core, usually without the running speed of the fibrous web being slowed down after the so-called "turn-up" in which the web is carried out is cut and guided to be wrapped around a new empty winding core. The smooth operation of the winder and especially the envelope is very critical to the function of the entire production line and it is therefore important
    1.10
    AT 16 593 U1 2020-02-15 Austrian patent office that the handling of the winding cores, the reel during winding and the finished reel is reliable and that the envelope can be carried out if necessary. Therefore, the winder is equipped with a winding core storage in which the empty winding cores can be stored ready for use when they are needed in the winder. The winding core bearing is usually formed from two guide rails, which are arranged on both sides of the winder, and the winding cores are supported on the rails by their bearing housing. If it is necessary to wind a new drum, a winding core e.g. transferred to the primary position of the winder for turnover (change) with a suitable lever mechanism in order to begin wrapping around the new winding core.
    It is known from the prior art to use winding core bearings of various types. One type of bearing has horizontal rails positioned upstream of the winding cylinder of the winder, another type has horizontal rails positioned downstream of the winding cylinder of the winder, and furthermore winding core bearings with vertical or inclined bearing positions on rails for winding cores are known. The present invention relates to a winder with a winding core bearing with essentially horizontal rails which are arranged upstream of the winding cylinder of the winder. A known example of this type of winding core bearing is disclosed in US Patent 4,778,122.
    In Fig. 1, an example of a winder (reel-up) 10 is known schematically, which is known from the prior art, in which a winding core bearing 20 of the aforementioned type, i.e. with essentially horizontal rails 24, which are arranged upstream of the winding cylinder 14 of the winder 10, is provided.
    The winder 10, which is shown in Fig. 1, has a winding cylinder 14, along the circumference of which the fibrous web W runs and against which a drum 13 is pressed during winding. The winding cylinder 14 is driven by a motor (not shown) by known methods. The winding cylinder 14 rotates and the drum 13 is formed around a winding core 11. The winding core 11 is mounted on bearings in bearing housings which rest on rails 15. A load roller (load roller) rotatably mounted in the bearings at the ends of secondary arms 18 loads the bearing housing by means of a load cylinder (load cylinder). Rails 24 of the winding core bearing 20 are arranged upstream and above or partially on the upper side of the winding cylinder 14 of the winder 10. Winding cores 11 are supported in the winding core bearing 20, their bearing housings being supported on the rails 24 of the winding core bearing 20. A transfer device 21 is pivotally mounted on the frame of the winder 10. Primary arms 17 of the winder 10 receive the winding core 11 from the transfer device 21, as shown by a movement line S, in a pre-start position. The primary arms 17 are mounted such that, in the pre-start position, the winding core 11 does not yet touch the winding cylinder 14 and only touches it after the primary arms 17 are rotated (swiveled) around the winding core 11 to a roll change position, as by a dashed line Line is shown to transfer along the line of movement S. The winding (rolling up) is started and a reel 13 is formed around the winding core 11, which is transferred to a secondary position with a support of the secondary arms 18. A finished reel 12 is moved along the rails 15 to an end position at the end of the rails, from where the finished reel 12 is transferred to a next process step. In these types of winders, the use of a space is sometimes problematic because the winding cores and the winding core bearing occupy an extremely large space. Furthermore, the handling of the winding cores can be complicated if separate transfer devices and primary arms are required, which also increases the cost of the winding construction. Furthermore, a rather poor visibility during the transfer of the winding cores by means of cranes to the rails of the winding core bearing can cause problems.
    An object of the invention is to provide a winder (reel) for a fibrous web that is simple, robust and reliable.
    2.10
    AT 16 593 U1 2020-02-15 Austrian Patent Office [0011] Another object is to provide a winder (reel) of a lower middle class price category, which can however provide sufficient means for winding (reeling) most types of fibrous webs.
    An object of the invention is to eliminate or at least minimize the disadvantages explained above in a winder (reel-up), which are in particular associated with a winding core receptacle from the winding core bearing, which requires a transfer device according to the prior art.
    To achieve the above objects, the winder is characterized above all by the features of the characterizing part of claim 1.
    According to the invention, the winder has a primary winding device which is designed to receive the winding core from the winding core bearing and to load (load) the winding core during winding (reeling) in the primary position during the primary stage and around lower the winding core to the secondary position.
    According to an advantageous feature, the primary winding device has a device for receiving, supporting, moving and loading (loading) the winding core and is formed from a lever mechanism with actuators, the actuators being arranged in essentially the same vertical plane.
    According to an advantageous feature, the guide rails of the winding core bearing are arranged such that the distance in a vertical direction between an upper surface of the winding cylinder and a lower surface of the winding core, which is arranged on the guide rails of the winding core bearing, is 5-200 mm.
    [0017] The invention will now be described in detail with reference to the accompanying drawings, in which:
    An example of a winder according to the prior art is shown schematically in FIG. 1; and FIGS. 2A to 2C schematically show an example of a winder (reel-up) according to an advantageous example of the invention.
    In the following description, like numbers and reference numerals are used to identify like elements in the different views that represent the invention.
    2A to 2C schematically show an example of a winder (reel-up) 10 which has a winding cylinder 14, a guide roller 16 for guiding the fibrous web W to the cylinder 14 and frame parts 25. The winder 10 also has, supported on the frame parts 25, a primary winding device 19 and a secondary arm 18 for each end of the winding core 11 / reel 13; 12 for moving and supporting the winding core 11 and thereby the reel 13; 12 on. The fibrous web W is wound around the winding core 11 into a finished reel 12 by means of a nip between the reeling cylinder 14 and the reel 13 during the winding, the winding (winding) in a primary stage in a primary position and in one secondary stage takes place in a secondary position. The winding cylinder 14 is driven by a motor (not shown) by known methods. The winding cylinder 14 rotates and the drum 13 is formed around a winding core 11. The gap load is formed between the reel 13 during winding and the winding cylinder 14 and is formed by the loading of the winding core 11 with respect to the winding cylinder 14 by the primary winding device 19 or by the secondary arms 18 depending on the stage of the winding. The winding core 11 is mounted on bearings in bearing housings which rest on horizontal transfer rails 15. The winder 10 also has a winding core bearing 20 in which the empty winding cores 11 are stored ready for use when they are needed in the winder 10. The winding core bearing 20 is formed from two horizontal guide rails 24, which are arranged on both sides of the winder 10. If a new drum 12 needs to be wound,
    3.10
    AT 16 593 U1 2020-02-15 Austrian patent office, a winding core 11 is transferred by the primary winding devices 19 to the primary position of the winder 10 for a turn-up in order to wind around the new one To start winding core 11 around. To move the winding cores on the guide rails in the winding core bearing, the rails 24 are inclined and provided with winding core stops 23. The guide rails 24 of the winding core bearing 20 are essentially horizontal rails which are positioned upstream of the winding cylinder 14 of the winder 10. The rails 24 of the winding core bearing 20 are arranged above the winding cylinder 14 of the winder 10 such that the distance between the upper surface of the winding cylinder 14 and the lower surface of the winding core 11, which is arranged on the guide rails 24 of the winding core bearing, in a vertical direction 5 - is 200 mm. The winding cores 11 are mounted in the winding core bearing 20, the bearing housings of which are supported on the rails 24 of the winding core bearing 20. The primary winding devices 19 receive a new winding core 11 from the winding core bearing 20 and, when the winding core 11 is supported, are rotated towards the primary winding position in which the new winding core is loaded (loaded) against the winding cylinder 14 by the primary winding devices 19 ) becomes. The winding is started and a reel 13 during winding is first wound around the winding core 11 in the primary position and then transferred to the secondary position with a certain desired diameter in order to be supported by the secondary arms 18 in such a way that the bearing housings of the winding core 11 lie on the rails 15. A finished reel 12 is moved along the rails 15 to an end position at the end of the rails 15 and is stopped by the stop device 22, from where the finished reel 12 is transferred to a next process step.
    2A, a spool 13 is loaded (loaded) during winding by the secondary arms 18, supported and moved onto the rails 15, and the fibrous web W is in the secondary position by the winding cylinder 14 around the winding core 11 wound. The reel 13 during winding rotates during winding, as shown by an arrow R. The primary winding devices 19 are turned (rotated) to receive a next new winding core 11 from the winding core bearing 20 to be ready to start winding the next reel. In this stage, the winding core 11 is arranged at a distance from the winding cylinder 14.
    In Fig. 2B, the winder 10 is shown in a situation in which the drum 12 has just been completed and the envelope (change) to the next winding core 11 has been carried out. The finished drum is moved in the direction of the end position by the secondary arms 18. The primary winding devices 19 are rotated to position the winding core 11 in the primary position, and the winding core 11 is supported and loaded (loaded) by the primary winding devices 19, and the fibrous web W is in the primary position by the winding cylinder 14 around the winding core 11 wrapped around. The winding core 11 / drum 13 during winding rotates during winding, as shown by the arrow R.
    2C, the winder 10 is shown in a situation in which the drum 12 has been completed and is arranged in the end position and is stopped by the stop device 22. The winding thus changes from the primary position to the secondary position. The primary winders 19 are rotated to lower the winding core 11 to the secondary winding position to be supported by the secondary arms 18. The winding core 11 is then supported and loaded (loaded) by the secondary arms 18 and the fibrous web W is wound around the winding core 11 in the secondary position by the winding cylinder 14. The reel 13 during winding rotates during winding, as shown by the arrow R.
    As shown in Figures 2A - 2c, the primary winding devices 19 have a device for receiving, supporting, moving and loading (loading) of the winding core 11. It is formed from a lever mechanism with actuators. The primary winding devices are pivotally supported on the frame parts 25 and each device has lever arms for gripping the ends of the winding core 11 on both sides.
