Description

Assembly for handling reels and reel-off device for a fiber web machine Technical Field The present invention relates to an assembly for handling reels and a reel-up (winding) -unwind device for a fiber web machine. Background A reel-up of web-like material is used to wind the material passing as a continuous web into a tight reel so that it can be transferred to further processing. For example, in a reel-up of a paper web, a continuous paper web passing from a paper machine, a coater or a corresponding paper handling apparatus is wound around a reel spool (reeling spool) to form a roll. The web is brought onto the reel via a reeling cylinder (REELING CYLINDER) which is arranged rotatable and against which the reel is pressed by means of a loading device provided in connection with the reel spool. Thus, the web enters the roll so that it is pressed between the first few layers (PRECEDING LAYERS) of the roll and the cladding surface (mantle surface) of the winding cylinder. In a papermaking line, the manufacture of a fibrous web, such as paper or board, is performed as a continuous process. The fiber web completed in the paper machine is wound by the reel-up around a winding shaft (REELING SHAFT) (i.e. reel spool) into a parent roll, which may be more than 5 meters in diameter and weigh more than 160 tons. The purpose of the winding is to change (modify) the fibrous web manufactured as a continuous sheet into a more manageable form. On a reel-up located in a main machine line (MAIN MACHINE LINE ), the continuous process of the paper machine is interrupted for the first time and is converted into a periodic operation. The web of the parent roll produced in paper manufacture is full width and may be more than 100km long, so that it must be slit into partial webs of a width and length suitable for the paper mill customer (required) before delivery from the paper mill (separator) and wound around a core into a so-called customer roll. Such slitting and winding of the web is performed in a suitable separate machine, i.e. a slitter-winder, as is known. On a slitter-winder, the parent roll is unwound, and the wide web is slit into narrower partial webs on slitting sections, which are wound into customer rolls on winding sections around winding cores (winding cores ) such as reels. When the customer rolls are completed, the slitter-winder is stopped and these wound rolls, the so-called group (set), are removed from the machine. The process then continues, wrapping a new set. These so-called group replacement steps are repeated periodically in sequence until the parent roll is exhausted, whereby parent roll replacement is performed, and the operation begins again as a new parent roll is unwound. Subsequently, the empty reel shaft is returned to the winding portion. The winding section must be provided with a new or empty winding shaft before the previous winding shaft is full, i.e. the parent roll is ready for roll replacement. Typically, a plurality of empty parent rolls are stored in a so-called spool storage (reel spool storage). Between the unwinding station and the winding section of the slitter-winder there is a circulation of the reel, wherein a full roll with the reel is transferred to the unwinding station and an empty reel is returned to the winding section. The corresponding reel circulation is also between, for example, a web production machine and an off-line coater or other web finishing machine. An example of a winding section according to the prior art is shown in document US5943787 a. The empty reel is typically returned to the reel-up by using a overpass crane (overhead bridge crane) of the machine house. Since a continuous return process of the reel is actually required, the use of the bridge crane to return the reel leaves the crane and its operator unused for other uses reduces the overhead crane's utilization. It is also known to automatically return the empty reel by means of a winding shaft handling device, as disclosed for example in document WO2010125232 A2. In this publication, reference is made to the return track and the movement of the trolley-based reel and machine rollers.
