    Method and device for lowering and / or lifting a winding shaft
    The present invention relates to a method for lifting a winding shaft from the lifting position of the winding shaft, which is arranged on rails or the like spaced from each other, in which method the winding shaft of the rails or the like by means of at least two gripping elements of a lifting device so raised is that the winding shaft is held by the gripping elements of the lifting device.
    The invention also relates to a method for lowering and positioning a winding shaft to the lowered position of the winding shaft, which is or are spaced apart on rails or the like, wherein in the method, the winding shaft carried by a lifting device provided with at least two gripping elements on the rails or the like is lowered.
    The invention also relates to a device for lifting a winding shaft from the lifting position of the winding shaft, which are arranged on rails or the like spaced from each other, or for lowering the same to the lowered position of the winding shaft, which is arranged on rails or the like spaced from each other or are, the arrangement having a gripping elements equipped with raising and lowering device by means of which the winding shaft can be raised and carried and from which the winding shaft can be lowered onto the rail or the like. 2 '2'
    When handling and storing thin and planar materials, such as a membrane, folio, or paper, it is known to wind the material on a winding shaft. In particular, when the roll is large, the handling of the roll by lifting requires a certain accuracy. A heavy roll can not be lowered too quickly or improperly positioned onto the roll shaft support because it can cause damage to the roll or to the material itself. For the same reason, the lifting of the roll from the support must also be performed in a controlled manner. Furthermore, the lifting device may experience damage if the lifting is performed too fast or otherwise poorly controlled and guided.
    In the production lines of a fibrous web, such as paper, papermaking is carried out as a continuous process. A paper web completed in a paper machine is placed on a reel on a winding shaft, i. H. a reel spool, wound to form a machine roll whose diameter exceeds 3.5 m and whose weight can be more than 100 tons.
    When the diameter of the machine roll has reached a predetermined size, the winding on empty reel spools is started without interrupting the pre-winding paper making process. The purpose of wrapping is to convert the manufactured flat web into a more easily processed form. On the reel-up, the continuous process of the paper machine is interrupted for the first time and cyclic processing is introduced. The goal is to perform this cyclic processing with the highest possible efficiency so that it can already «* · * · *» · II 2 1 * * * ** * * do not lose work done. Rollers or the like, whose ends are mounted in bearings and whose axis passes through the bearings and is provided with a coupling for connecting the winding shaft to the drive, are commonly used as winding shafts. The storage system typically includes a bearing housing whose periphery is shaped to include a groove so that the winding shaft can be stored either with a particular start-up of its operating rollers or on rails or the like.
    On a papermaking line, certain qualities after the manufacturing process may be subjected to processes such as coating or handling that affect the surface characteristics of the paper, e.g. B. calendering. These processes may include treatments that are performed either in a separate device or in connection with the manufacturing process. The web on a machine roll produced in papermaking has full width and is even more than 100 kilometers long, which is why it has to be cut into sub-webs of suitable width and length for paper mill customers and wound on core tubes to form so-called customer rolls before they can be delivered by the paper mill.
    Therefore, the processes taking place in a papermaking line require the transport of machine rolls and their winding shafts from one process to another. Due to the heavy weight of a machine roll, the transport of machine rolls in conjunction with the prior art process is typically performed along rails, • · * · •
    which are supported and held by machine elements arranged therein.
    The lowering of a winding shaft on rails, especially when a full machine roll is wound on the same, a process step that requires a very high precision. If the winding shaft or machine roll is not lowered in the transverse direction of the machine (in the longitudinal direction of the winding shaft) to an exactly correct position, it frequently happens that the machine roll or winding shaft falls into the correct groove during its rolling movement by up to 30 mm , which causes damage to the machine roll in the form of bends.
    The cranes are usually provided with lifting hook vertical position measuring devices, which take into account the tension of the wire drawing rope, whereby the drop height of the load can be relatively accurately controlled. A force caused by a blow is applied to the winding shaft or machine roll when it is lowered. In order to minimize this impact in practice, the lowering speed should be very low, but a low lowering speed delays the sequences and prolongs the working cycle of the crane. Therefore, an object is to minimize the last deceleration during the lowering of the winding shaft to be handled.
    The exact position of the crane hook depends on a variety of things, such as the accuracy of the crane track, the flexibility of the structures, the dimensional changes of the building as a function of time.

    The handling of machine rolls and winding shafts is therefore of great importance for the operation of the production line. Furthermore, the number of winding shafts is usually so high that they have to be temporarily stored in the production line when they are empty. Also full machine rolls, d. H. Winding shafts, when forming cores of the machine roll, are temporarily stored during the production process.
    An object of the invention is to provide a method for lowering and positioning a winding shaft to the lowered position of the winding shaft, which is spaced on rails or the like, wherein in the method the winding shaft carried by a lifting device provided with at least two gripping elements the rails or the like is lowered, wherein the lowering takes place to an exact position.

    FIG. 1 shows an embodiment of the device 10 according to the invention for lowering and positioning a winding shaft 15 onto the lowering or lifting position 20 of the winding shaft or for lifting the winding shaft from the lowering or lifting position. Figure 2A shows the section II-II of Figure 1. In the situation shown in Figure 1, the winding shaft 15 is empty and is lowered onto rails 25 or the like. A full machine roll can also be wound on the winding shaft. Fig. 1 is shown in the longitudinal direction L of the winding shaft, and although not shown in the figure, the rails 25 may be very long in practice in the vertical direction with respect to the longitudinal direction L of the winding shaft. On the other hand, the rails or the like may also be relatively short, for example when the lowering or lifting position 20 consists of the storage platform of the winding shaft. In other words, the rails or the like can only be long enough in the shortest pallet to accommodate the winding shaft 15 lowered thereon.
    The outer surface of the winding shaft 15 has a substantially cylindrical body part 15.1 and arranged at the ends thereof shaft journals 15.2. The ends of the shaft journals are provided with couplings 15.3 for connecting the drives to the winding shaft. Typically, the winding shaft is supported by bearing housings 30 on the base, such as rails 25. The winding shaft 15 is supported by the bearing housing 30 rotatably mounted on the base. Between the bearing housing 30 and the body part 15.1 of the shaft journal is provided with an area from which the winding shaft by means of gripping elements, such as hooks, a lifting and lowering device 45, d. H. a crane can be lifted. Then, the rotational movement of the winding shaft 15 is locked in the hook 40 during lifting, and the machine reel wound on the winding shaft can not be unwound during lifting.
    In order to be able to lower the winding shaft in an exact lowered position or lowered position and the gripping elements, d. H. the hooks 40, to direct to an exact raised position relative to the winding shaft, the device according to the invention comprises elements 100 which correspond to the position of the gripping elements, i. H. the hook 40, to position the gripping members 40 with respect to the rails 25 or the like for use in both lifting and lowering situations. • ♦ • 4 »* • r« »* • ·« · 4
    In the embodiment of Figure 1, the outer surfaces s of the hooks 40 are substantially planar, at least in the lower portion of the hook, which extends to a distance D from the outer surface of the bearing housing 30 while the winding shaft is carried by the hook. Both rails 2 5 have elements 100 which are intended to act during the lowering operation on the position of the hook 40 for positioning the gripping elements 40 and thus the winding shaft 15 on the rails 25 or the like. The elements also guide the hooks 40 to a correct lifting position 20 during the lifting process. In this embodiment, the elements 100 have a mechanical positioning device 110 which extends from the inner edge of the rail 25 to a further distance LI than the bearing housing 30 of the winding shaft 15 in the direction of the area between the rails. The positioning device 110 mechanically controls the position of the hook 40 with respect to the rail 25 during lowering. This is embodied in FIG. 1 such that the positioning device has a guide surface 115 which, in the lowered position, approaches the surface 41 of the gripping element in the lowering direction of the gripper element. This is achieved by arranging the positioning device 110 in the upper part of the guide surface 115 with a shorter distance LI from the inner edge of the rail 25 than the distance L2 set in the middle region of the guide surface 15. The distance L2 is longer than the distance that the bearing housing 30 of the winding shaft 15 extends from the groove, which extends as a bearing point 35 of the bearing housing 35 in this direction. Thus, the positioning device has a beveled guide surface whose upper edge is closer to the mounting surface of the positioning device and the rail body than the central region 116 thereof. 12 * * · Λ «
    Furthermore, the positioning device 110 is arranged in the lower part of the guide surface 115 with a smaller distance LI from the inner edge of the rail 25 than the distance L2, which is defined in the central region 116 of the guide surface 115. This makes the guide of the hooks 40 exactly when the hooks 40 are brought in the direction of the shaft journals 17 of the winding shaft in the lifting step. Thus, the positioning reduces the tolerance of the gripping elements while approaching the gripping elements to the final lowering or lifting position.
    The device is used in the lowering situation so that the winding shaft carried by a lifting device provided with two gripping elements is lowered onto rails or the like, so that the winding shaft is supported by the bearing housings arranged substantially at the ends of the winding shaft, and the positioning of the winding shaft on the rails or the like is guided by controlling the position of at least one gripping element carrying the winding shaft with respect to the rail. This is achieved according to an embodiment by substantially directly acting on the position of the gripping elements.
    The apparatus is used in the lifting situation such that the winding shaft is lifted by the two gripping members of the lifter from the rails or the like so that the winding shaft is supported by the gripping members of the lifter, and before lifting the winding shaft from the rail or the like the gripping elements are brought to the winding shaft at the same time as the positioning of at least one gripping element to the lifting position by adjusting the position of the gripping element with respect to the .1 * .. * * .. * i3. *
    Rail or the like is controlled by acting on the gripping element.
    The positioning device may be a separate part, i. H. a guide member attached at a specific point in the frame structure of the rail 25, or it may be embodied as an integral part of the frame structure of the rail or as a shape of the frame structure. The positioning device 110 can be made of a partially or completely flexible material and it can also be designed to be movable, so that it can be led away from the path of the gripping elements, if necessary. Preferably, a positioning device 110 is arranged in connection with both rails 25, whereby the longitudinal positioning L of the winding shaft to the lowering position is symmetrical and therefore more accurate. Thus, the position of both the winding shaft 15 carrying gripping elements 40 is controlled with respect to the rails at the last step of the lowering situation.
    The rails 25 are arranged at a distance from each other in the longitudinal direction L of the winding shaft, so that the distance between the rails corresponds to the distance between the support points 35 of the bearing housing 30 in the winding shaft to be driven.
    The arrangement of Figure 1 is operated in the lowering situation so that the positioning device 110 is in the rails at the last step of the lowering movement of the winding shaft in direct contact with the hook.
    The invention also includes a device for lifting the winding shaft from the lowered position of the winding shaft, d.

In this way, the position of the gripping elements on the shaft journal 17 of the winding shaft 15 is more accurately positioned to be correct while the lifting is started. Preferably, the elements intended to act on the position of the gripping elements act on the position of the gripping elements with respect to the winding shaft during the raising or lowering, respectively.
    The size and height of the positioning device 110 is such that the release and removal of the hook 40 after lowering is unhindered.
    FIG. 2b shows a further embodiment of the elements 110 according to the invention. Here, the elements for positioning the gripping elements also have a mechanical positioning device 125, which in connection with the gripping element, d. H. the hook 40 for controlling the position of the gripping member with respect to the rail 25 at least in the transverse direction with respect to the longitudinal direction L of the winding shaft. In addition, in this embodiment, the mechanical positioning device 110 in conjunction with the rails has a groove 126 or the like on its guide surface 115, the transversal dimension of which decreases downwardly with respect to the longitudinal direction L of the winding shaft from the upper edge, i. H. in the lowering direction of the winding shaft 15. In the same manner, the transversal dimension of the groove 126 or the like with respect to the longitudinal direction L of the winding shaft decreases from the lower edge of the winding shaft 16 Positioning device upwards. The groove extends in the vertical direction through the entire positioning device 110, wherein the hook can be brought low enough to release the winding shaft of the hook in the lowered position. The transverse dimension of the groove 126 with respect to the longitudinal direction L of the winding shaft and the dimension of the in connection with the gripping element, d. H. the hook 40, arranged positioning means 125 and the shapes thereof are such that, while the winding shaft is lowered onto a rail, the positioning device 125 is guided on the hook in the groove 126 or the like and thus the winding shaft in the transverse direction with respect to its longitudinal direction L positioned while the guide surface 115 at the same time leads the hook by acting on its outer surface and the winding shaft in its longitudinal direction L positioned.
    As shown in Fig. 2d, the winding shaft 15 is lifted by the two gripping members 40 of the lifter from the rails 25 or the like, so that before lifting the winding shaft 15 from the rails or the like, the gripping members 40 are brought to the winding shaft at the same time to which the positioning of at least one gripping member 40 to the lifting position is controlled by adjusting the position of the gripping member with respect to the rail or the like by acting on the gripping member. In the lifting situation, the positioning means 125 for the gripping member 40 is guided in the groove 126 or the like, and thus the hook 40 is positioned in the transverse direction with respect to the longitudinal direction L of the winding shaft, while the guide surface 115 simultaneously the hook by acting on its outer Surface leads to a correct lifting position on the shaft journal 17 of the winding shaft.
    Figure 2c shows a situation similar to Figure 2a except that the winding shaft is lowered onto pedestals or a trolley 26, the rails being very short.
    Figure 3 shows a further embodiment of the device 10 according to the invention for lowering and positioning a winding shaft 15 to the lowering or lifting position 20 of the winding shaft or for lifting the winding shaft of the lowering or. Lifting position 20. Figure 4 shows the section II-II of Figure 3. This embodiment corresponds to the embodiment shown in Figure 1 and also here both rails 25 have elements 100, which are provided for the position of the hook 40 for positioning the gripping elements 40 to act on the rails 25 or the like. The elements 100 in this embodiment have an electronic positioning device 120, which is provided to determine the distance of the hook 40 to the rail 25 and / or its frame structure. The electronic positioning device 120 is configured to communicate with the control device of the crane (not shown). In practice, the electronic positioning device 120 is preferably a distance measuring device which determines the distance of the hook 40 from the rail 25 and / or its frame structure, and the movement of the crane hook 40 is based on the measured distance at least during the last delay of the lowering or during the lifting just before the hooks 40 engage in the winding shaft controlled. According to one embodiment, the operation of the crane is designed to depend on the distance measurement at the last step of lowering. Preferably, the operation of the crane is intended to depend on the distance measurement at the last step of lowering so that the lowering speed of the hook 40 of the distance measurement in particular depends so that the shorter the distance between the hook and the frame structure of the rail or a special other reference point 121, the lower the speed. FIG. 3 shows (left side) that the reference point 121 may be a mechanical positioning device 110 or (reference side) the reference point may be arranged in a separate reference piece.
    By means of this type of control, the final delay can be activated later than before, whereby the entire boosting process can take place within a shorter time than before. As shown in FIG. 3, the positioning device 120 is arranged on both hooks 40. In this way possible asymmetry effects can be minimized and the winding shaft can be lowered more accurately than before in a correct position on the rails. FIG. 3 also shows that the arrangement can be provided simultaneously with both an electronic positioning device 120 and a mechanical positioning device 110.
    It should be noted that only a few of the most advantageous embodiments of the invention are described above. It is therefore to be understood that the invention is not limited to the embodiments described above but can be applied in many ways within the scope of the appended claims. The features described in connection with the different embodiments may also be used in connection with other embodiments and / or various combinations of the described features may be made within the scope of the basic idea of the invention, if desired and if the technical feasibility thereof consists.
