    Technical environment
    The invention relates to a rotating device and a method for machine rolls. The invention is particularly, but not exclusively, concerned with rotating machine rolls between winding and unwinding phases in fiber web machines, preferably in paper and board machines.
    Background of the invention
    In papermaking lines, the production of paper is carried out as a continuous process. The paper web output from the paper machine is fed by a winder around a winding shaft, i. H. a reel spool, wound in a machine reel, whose diameter may be more than 5 m and which may weigh more than 160 t. The purpose of winding is to bring the paper web from its planar manufacturing mold into a mold which can be handled more easily. At the rewinder, which is arranged in the main machine line, the continuous process of the paper machine is interrupted for the first time, after which the process is continued in stages. Every attempt is made to connect these steps as smoothly as possible so that the work already done is not wasted.
    In a fiber web manufacturing process, during winding, transport of a machine roll in the process forward typically occurs by rolling along rails either on the basis of gravity (inclined rails) or moved by a separate transport device. The forward movement of the winder may also be performed using a lifting device, such as a hoist. The machine roll is normally brought by means of a hoist to such a slitter, which is not connected to the paper machine and has transport rails, and lowered onto the transport rails, which are typically arranged so that the height of the center of the machine roll from the floor surface about 2.5 m is.
    The web of the machine roll produced during papermaking runs across the entire width and is over 100 km long, so it is cut into sub-webs of a suitable width and length for the customers and wrapped around cores in " customer roles " must be wrapped before it can be sent off the paper machine. As is known, this cutting and winding of the web takes place in a machine designed for this purpose, i. H. in a slitter. During the manufacturing process, in some cases, the machine roll must be rotated. A phase or apparatus of the production process may require changing the position of a free end or tail WT of the machine reel 1 to an opposite end WT of the machine reel 4 (Figure 1) with respect to the post-winding position. It is desired to rotate the machine reel 4 during the manufacturing process to avoid the one-sidedness in another J3 9999 99 ·· 9 9
    Process phase (eg coating, calendering) and finally in the customer roles to control. A first side Wx of the fibrous web typically has different properties than a second side W2 of the fibrous web (Figure 2) and it is also characteristic of fibrous web manufacturing apparatus that they do not produce a similar process impact on both sides of the fibrous web without additional effort.
    A hoist 8 (Figure 3) is typically used to rotate the machine reel, the hoist being equipped with a separate turning bar 9 for this purpose. Turning may also be performed with an on-rail machine roll carriage using bogies or by creating a solid turntable at the rotational position of a rail car (used, inter alia, in rail vehicle applications).
    When a machine roll in the lateral direction from a fixed by a winder rail line z. B. must be moved to another slitter, which can be arranged in a corridor of the building, typically a rail-supported on a ground machine roller carriage for lateral transport is used. With a machine-roll carriage movable on rails, it is possible to move and transfer machine rolls on the rails of the receiving station or to lift them with a hoist. The machine roll is loaded from the end of the transport rails onto the machine roller carriage or with a j4-; · · · 9 »··· ··« 9 9 ·
    Hoist raised. The rotation of the machine roll, carried out with transport rails, requires a lot of space, has a complex implementation and is expensive.
    For example, in prior art solutions for handling winding shafts, it may be difficult to create ways of the winding shaft and machine roll transport trucks, and transport rails and transfer and conveying paths of gantry cranes in a flexible manner to changing requirements such as the requirements of the cyclic process of machine rolls. Moving and rotating winding shafts and machine rolls requires special requirements and space for transfer cars, which are guided on rails and / or wheels. The machine roll handling solutions typically require expensive concrete and steel girder structures, designed according to the full machine roll, to hold lifting devices, such as hoists. The capacity of the hoist can be maintained, in which case the hoist may not be able to respond to short-term transporter requirements.
    The turning bar required when turning with the hoist is an expensive and separately detachable attachment. A rotating mechanism of the rotary beam is under extremely high tension when all the machine rolls are rotated, resulting in costs and a space requirement due to a replacement machine or spare bar. • * * F- •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••
    A need to increase the height of the machine hall by even more than 1 m is caused when the turning bar is used. Turning with a hoist above the machine line requires a lot of space, which makes the machine hall longer because the space in question can not be used to store machine rolls. The attachment must be stored within the operating range and the attachment must be attached or disconnected separately according to the desired operating purpose of the hoist (maintenance, etc.). The transportation, and particularly the hoisting, results in a safety hazard, which limits the movement of operators etc. in the area and causes delays in normal operation.

    In FIG. 4, the machine reel 4 can be moved by means of rail gates or rail closures 6, which can be connected to transport rails 5, to the rotary carriage 10, but the machine reel 4 can also be lifted to the rotary carriage 10 by means of a hoist or a comparable handling device. The structure of a frame 11 of the trolley 10 is preferably based on a steel profile that holds well the mass to be stored in the vertical direction. The rotary cart 10 is preferably designed to accommodate heavy, full machine rolls 4. As a receiving position, the frame 11 may include a slot 12 for shaft ends 2 of reel spools 1 of the machine reel 4 and / or forms of actuators which perform a stopping or parking function of the machine reel.
    Fig. 6 shows the machine reel 4 of Figures 4 and 5 from below. Air cushion elements 40 are mounted below the trolley 10 at both of its ends. As a guide means for rotating the trolley 10 of the device, a counter-mold 140 is disposed on the trolley, preferably below the trolley, for a guide mold arranged in the floor, wherein the guide mold 130 and counter-mold 140 arranged in one another are a rotation axis of the trolley 10 and thus set the machine reel 4. In FIGS. 4 and 5, the guide shape in the bottom is formed by a shaft 130, which is preferably tubular and which adjoins a • Φ • Φ Φ-16- • · · * • Φ ··
    Bore 140 is adapted, which is arranged below the trolley and serves as the counter-shape of the shaft.
    According to some embodiments, the bottom-supported shaft 130 may be adapted to move in a longitudinal shape, such as a straight groove 141, an example of which is shown in FIG. The shaft 130 moving in the longitudinal shape 141 allows a linear movement of the trolley and thus of the machine reel, preferably close to the transport rails and away from the transport rails.
    Of course, a comparable shaft can also be arranged on one side of the trolley 10, wherein the shaft is held by a bore formed in the bottom or by another counter-mold, which can also be longitudinal.
    At both load-bearing ends of the trolley 10, two air cushion elements 40 are provided. An optional shape of the frame of the trolley 10 when viewed from below is shown by a dot-dash line 11 '. The air cushion elements 40 are preferably located at the ends of the truck 10 and the load generated by the mass of the machine reel 4 is transmitted to the region of the ends via the shaft ends 2 of the reel spool 1.

    Air duct or an air coupling connected, which are arranged in the rotary truck. A compressed air coupling is preferably of a type that allows the turning of the trolley. This allows the use of fixed compressed air supply lines, thereby avoiding the use of hoses and providing a structure which will wear less and require less maintenance of the hose structure. The supply channels for compressed air can then be arranged protected within the soil.

In some embodiments, the ground supported shaft 130 may be moved along the groove 141 provided in the floor (FIG. 8).
    A rotatable wheel 160 disposed below the trolley may be used as an actuating mechanism for rotating the trolley 10, which wheel may be supported on the frame 11 of the trolley in a loadable manner in the direction of the ground. The wheel 160 may preferably be rotated in either direction to allow the turntable 10 to rotate clockwise and counterclockwise. At least one rotatable wheel 160 is disposed at a distance from the rotation axis of the truck, preferably close to an end portion of a rotation range. Preferably, a rotational direction of a surface of the wheel 160 on a floor surface is transverse with respect to a longitudinal direction of the frame 11 of the truck. Preferably, at least two wheels 160 are disposed on opposite sides of the axis of rotation of the trolley. The wheel 160 is preferably supported on a drive 161 which is hinged to the frame of the truck and the rotation of the wheel 160 is performed by a motor which is preferably powered by compressed air and therefore a common supply of pressurized air to the air bag elements can use. The motor (not shown in the figures) can also be designed as an electric motor.
    The above-mentioned shaft 130 can also be used as an actuating mechanism for rotating the rotary truck 10 of the rotary device, the shaft having a rotating actuator, such as a
    -19- * Φ 9 Φ Φ 9 Φ Φ ΦΦ ΦΦΦΦ ΦΦΦΦ rotating motor (not shown in the figures) can be connected. According to some embodiments, the rotatable shaft 130 may be moved in the groove 141 for the linear motion 150. The rotary actuator of the shaft may be mounted on the rotary truck 10, which shaft should be attached to the ground with reference to the direction of rotation. The rotary actuator of the shaft may be attached to the ground, and the shaft should be mounted on the rotary truck with reference to the direction of rotation.
    A sprocket supported on the ground and a gear in tooth engagement with and rotatable by means of a motor, the sprocket being supported on the trolley, may also function as an operating mechanism for rotating the trolley 10 of the rotating device can be used (not shown in the figures). Further, according to an embodiment, a ring gear supported on the rotary truck and a gear meshing with the ring gear and rotatable by means of a motor, the gear supported on the ground, may be used as an operating mechanism used (not shown in the figures).
    The rotary cart 10 may have a separate locking solution for the machine reel 4 when the machine reel 4 by means of a transport element for machine rolls, for example by a
    Rail closure 6 is moved to the rotary truck. In Fig. 5, a machine roll 4 by means of a
    Rail closure 6 and a transport element placed on a rotary carriage, in which case an additional locking mechanism for the machine reel 4 is required. The movement of the rail closure 6 connected to a transport rail 5, 5 'by means of a connection 7 is represented by an arrow 6'.
