    Method of handling a fiber web winder supplied empty
    winding shafts
    The invention relates to a method for handling empty winding shafts fed from a fiber web unwinder, wherein machine rolls produced in the method on a winder are handled in one or more process sections following the winder and the winding shafts empty thereby are returned to the winder.
    As is known in the art, paper is made in machines which together form a papermaking line which can be hundreds of meters long. Modern paper machines are capable of producing more than 450,000 tons of paper a year. The speed of a paper machine may exceed 2,000 m / min (120 km / h) and the width of the paper web may be more than 11 m.
    In papermaking lines known in the art, papermaking is a continuous process. A paper web produced on a paper machine is wound with a winder around a winding shaft, that is a reel spool, into a machine reel whose diameter can exceed 5 m and whose weight can exceed 160 tons. The purpose of the wrapping is to convert the paper web made in planar form into a more easily processed form. On the winder, the continuous process of the paper machine is interrupted for the first time and a change to a periodic operation is performed. The goal is to create the periodic t * * * * · · · · · «* * * * * * * * *« · · · · * * I * * * Ml * I * · · 2
    Operate as efficiently as possible in order not to destroy the work already done.
    The machine roll web produced in papermaking runs across the entire width and can exceed 100 m in length and must therefore be slit or cut into sub-webs of suitable width and length for the customers of the paper mill and wrapped around cores in so-called customer rolls before they leave delivered to the paper mill. The cutting and winding of the web takes place in a manner known from the prior art in a suitable, separate machine, that is, a slitter.
    As is known from the prior art, the machine roll is unwound in the slitter, the broad web is cut in the cutting section into a plurality of narrower partial webs, which are wound on the winding section around winding cores, such as spools, in customer rolls. When the customer rolls are completed, the slitter is stopped and the rolls, that is the so-called set, are removed from the machine, after which the process continues with the winding of a new set. These steps or sections are repeated periodically until the paper leaves the machine roll, whereupon the machine roll is changed and operation begins again by winding a new machine roll.
    In high-speed papermaking lines known in the art, a papermaking machine can produce more paper than a single slitter can handle, which is why multiple slitters in the line are used. · A · * * a ·••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• A control room or corresponding arrangements for the machines are often arranged in the space between them.
    In prior art layouts, the first slitter is typically typically formed as a so-called in-line slitter, which means that it is positioned in line with the paper machine, that is, in the main machine line. The second slitter is a so-called offline slitter, that is, it is not located in the center line of the paper machine, but usually next to the first slitter in its own, so-called corridor, that is in an extension of the built for the same engine room. Both slitters produce customer rolls that are transported by roller conveyors, for example, first to the roll wrapping machine to be packaged, and finally to a warehouse before being delivered to the customers.
    In prior art slitter cutters, a machine roll is normally taken by a hoist to a slitter in the papermaking machine line, but not connected to the paper machine with transfer rails, and lowered onto transfer rails, which are typically arranged such that the height of the center of the machine roll from the ground level is about 2.5 m. In embodiments in which the paper machine winder and winder are interconnected by transfer rails, the machine roll is transported along the transfer rails from the winder to the winder.
    The prior art transfer rails for full machine rolls consist of horizontal or inclined rails with waiting stations. A machine roll is transported from one holding station to another until it reaches an unwinding station. On horizontal transfer rails, the transport by means of a transport or. Transfer device and performed on inclined transfer rails by gravity, by allowing the machine roll to roll along the inclined transfer rails, the waiting stations are provided with mechanisms for stopping the machine roll and releasing them in the direction of the unwinding.
    As is known in the art, the unwind station typically consists of two unwind racks (front and drive side) which support the machine reel during unwinding. Articulated locking arms are provided in the unwinding racks, by means of which the machine reel is locked in place for the duration of unwinding. The machine roll in the unwind station is connected to a brake generator which operates as the unwinder actuator.
    As is known in the art, after unwinding, the idled reel spool, that is, the winding shaft, is usually either manually removed by lifting with a hoist or automatically by means of a reel spool handling device from the unwind station. The reel spool handling device consists of either vertical lifters • 5 * * or swing arms and upper return rails for empty reel spools. An empty or nearly empty reel spool is lifted onto return rails with a lifting device or with lifting arms on which there are usually several return station points. The return station (reel storage) is typically located above the unwinding or cutting and winding section. On the return rails, the reel spool is transported from one station to another either by means of the transfer means or by gravity by means of rollers by means of the stop and release mechanism. An empty reel spool is removed from the return rails and transported by means of the hoist or partially by means of a machine roller carriage on the winder of the paper machine.
    The devices known from the prior art require various lifting movements at one or more steps and normally a hoist is used for them. The hoist may typically be a overhead crane or a gantry crane supported on the floor level. The hoist is usually controlled manually by an operator. Some of the functions of the hoist may be automated, for example, such that the operator confirms the starting situation and the direction and destination, and instructs the hoist to perform the lifting, transporting and settling automatically. It is also possible to carry out a substantially fully automatic handling device for winding shafts based on the use of hoists, which however requires closed safety areas or corresponding safety measures which increase the costs of the device. Lifting the massive winding shafts, which weigh more than 30 tons, sets the
    Shafts and their bearings from different types of damage and exerts considerable forces on the rail structures and foundations, which must be taken into account by reinforcing the structures, which in turn brings additional costs.
    The object of the present invention is to provide a method by means of which the problems and disadvantages described above can be substantially eliminated.
    To be able to achieve the object of the invention, the method according to the invention is characterized in that in the method an empty winding shaft is fed to the winder by a lateral transfer movement to a position which precedes the winding roller of the winder in the process sequence.
    The invention will be described in more detail below with reference to the figures of the attached drawing, wherein:
    Figure 1 is a schematic side view of a
    Winder cutting arrangement in connection with which the present invention can be carried out,
    Figure 2 shows a schematic plan view of the arrangement of Figure 1, and
    Figure 3 shows a schematic side view of another roll cutting arrangement in connection with which the present invention can be carried out. • «• ·

    Figures 1-2 schematically show a
    Slitter assembly in connection with which the method according to the present invention can be applied. The arrangement shown in the figures shows a winder 1, in which a paper web produced in the paper machine {not shown) is wound on a winding drum 4 in a machine roll 3 about a winding shaft, that is, a reel spool 2. Completed machine reels 3 are transported along transfer rails 15 to a standby or waiting station 5, from which the machine reels 3 are transported further along transfer rails to an unwinding station 11 of the reel cutter 10. In the illustrated application, the unwind station 11 is at the machine level M and the winding section 12 of a cutting and customer roll winding section 12 is located in a space below the machine level. The cutting and winding section of the roll cutter in the bottom may consist of an aggregate having both a cutting and winding section and a winding section, or the cutting and winding section may consist of two separate aggregates, one of which is the cutting and winding section and the other has the winding section. From standby station 5, the machine rolls are transported to unwind station 11 for unwinding, and after unwinding, empty reel spool 2 is transported to return station 14, which simultaneously remains as a store for empty reel spools 2 and, if broke, on reel spool 13 , preferably also serves as a discharge point for broke layers by placing a pulper (not shown) below the return station. At the storage point rotates one
    Machine roll rotator feed the lower layers of machine rolls into the pulper. The same location and same device can also be used to unload any
    Paper broke layers or even used to unload an entire reject machine roll in the pulper. In the above arrangement, the machine roll transfer rails of a so-called roll-type, that is, the unwinding station is also rolling, whereby the handling of the machine rolls or winding shafts is straightforward and simple.
    In the method according to the invention, the transport of a plurality of bobbins from the return station is preferably carried out by means of a lateral movement, for example by means of a transfer carriage 20, which moves on the floor surface, by means of the carriage, the winding shaft further supplied to the winder and to a Point can be transported, which precedes the winding roller 4 of the winder 1, and that, by means of a lateral transfer movement. In this application, the winding roll refers to a winding drum or other roll of the winder against which or on which the machine roll is formed. The path or path of the transport path is preferably arranged in such a manner that the height of the winding shafts does not change significantly during the transport section or the transport sections. One major change relates to the maximum difference in the height of the machine rolls relative to the winding roll of the winder over the entire handling area, the difference being determined by the angle of inclination, at least the size of the radius of the winding shaft or, if gravitational machine roll transfer rails are concerned. FIG. 2 shows schematically by means of arrows A-C the transfer path of the winding shafts from the bearing 14 to the position preceding the winding shaft 4.
    Figure 3 shows schematically an alternative
    Slitter-winder arrangement in which the parts corresponding to FIG. 1 are designated by corresponding reference numerals. The arrangement in FIG. 3 differs from the arrangement in FIG. 1 in that the roll-cutting and customer-roll winding section 12 is also positioned substantially on the machine plane M. With this arrangement, the empty reel spool 2 formed in the unwind station 11 is preferably moved onto the transfer carriage 20 located in the area between the unwind station 11 and the cutting and winding section 12, and then laterally by means of the transfer carriage Transfer movement away from the unwind station.
    By transporting the winding shafts according to the invention in a controlled manner, substantially horizontally at the different sections of the transport, damage to the shafts and their bearings is prevented and the forces exerted on the rail structures and foundations are reduced. The dynamic coefficients used in dimensioning can be reduced and savings can be made in material costs. This is particularly reinforced by the continuous increase in the masses of the winding shafts, these masses are currently in the amount of 30 tons. The solution according to the invention does not require any substantial transport of the winding shaft in the direction of gravity or against it. Transports of the winding shaft in the horizontal direction are, for example, by means of roller carriages, hovercars, conveyors, forklifts, straddle carriers or • ♦ • · t ** m · · · · · · · Φ * · · · «· · · · · · · · · · ft 10 are performed by means of similar devices that are substantially different from a hoist. The carriage may run on the floor surface, for example, on wheels, on an air cushion or on rails arranged on the floor surface, for example held by rails provided on the side or above the carriages which are on the floor surface are supported. The return chain of the winding shaft to a preceding position to the winder can either fully automatically operate from the subsequent process section or sections in a most preferred embodiment, the winding shaft to the unwinding station or the unwinding of the subsequent process section or the process sections by means of a transfer device to the side is moved, such as with a roller carriage, or partially automatically, wherein a partial function can be provided, which can be performed by a hoist in conjunction with the unwinder, after which the winding shaft by means of the transfer device, such as a roller carriage, all the way is transported to the winding roll of the winder preceding position.
    The solution according to the invention does not extend the machine layout because, if necessary, the quality measuring devices etc. are arranged at a different height with respect to the transfer distance of the winding shaft. The method according to the invention is applicable in connection with any winder which winds a paper, paperboard or fabric web.
    The solution according to the invention makes a fully automatic handling of winding shafts and a simpler and more economical application of the required
    Safety precautions as possible with a hoist based arrangement. For example, the safety precautions may be implemented in accordance with the principles of currently used roll carriage solutions (motion detectors, etc.) without the need for closed safety area arrangements, etc. required in automated hoists.
