Installation for feeding paper reels to a reel stand and method for its operation

Abstract

A pit ( 14 ) along which a moving platform ( 15 ) with a transverse continuous track section ( 16 ) is displaceable is arranged at a reel stand ( 12 ). Feed tracks ( 10, 11 ) and also a plurality of storage tracks ( 17 ) in the form of stub tracks and intended for receiving carriages ( 6 ) each having a prepared paper reel ( 5 ) abut the lateral edge of the pit ( 14 ). Further storage tracks ( 17 ) are arranged on the opposite side of the pit ( 14 ), in each case aligned with one of said storage tracks ( 17 ) or a feed track ( 10, 11 ). During printing, the carriages ( 6 ) parked on the storage tracks ( 17 ) are fed as required via the moving platform ( 15 ) to the reel stand ( 12 ) and the paper reels ( 5 ) are mounted in the axis.

1 . Installation for feeding paper reels whose diameter does not exceed a maximum diameter to at least one reel stand having unwinding axes parallel to a transverse direction, comprising a pit which is of constant width and extends away from the reel stand in a longitudinal direction making a right angle with the transverse direction of said reel stand, and a moving platform displaceable in the longitudinal direction in the pit and having a track section which is continuous in the transverse direction from one longitudinal edge of the pit to the other, and comprising at least one feed track leading on a feed side in the transverse direction to the longitudinal edge of the pit, characterized in that at least one storage track leading away from the longitudinal edge of the pit ( 14 ) in the transverse direction is arranged on the feed side, and at least two such storage tracks are arranged on a side opposite thereto, in such a way that the lateral distance of each storage track from each other storage track arranged on the same side or feed track is greater than the maximum diameter.  
     
     
         2 . Installation according to  claim 1 , characterized in that the storage tracks are in each case in the form of stub tracks.  
     
     
         3 . Installation according to  claim 1 , characterized in that each storage track on the opposite side is aligned with one of the storage tracks on the feed side or with a feed track.  
     
     
         4 . Installation according to  claim 1 , characterized in that the feed track or a supply track connected to it leads via an unpacking station.  
     
     
         5 . Installation according to  claim 1 , characterized in that it comprises a plurality of carriages which are capable of moving on the at least one feed track, the track section, the storage tracks and, where applicable, the supply track.  
     
     
         6 . Installation according to  claim 1 , characterized in that it comprises a crane arranged on the reel stand and intended for removing reel cores.  
     
     
         7 . Method for operating an installation according to  claim 1 , characterized in that the paper reels are in each case unpacked before being fed to the pit, provided with an adhesion point and placed on a carriage, whereupon the carriage is moved via the at least one feed track onto the track section of the moving platform which is aligned with said feed track and, at least in the case of a part of the paper reels, in each case the moving platform is displaced until the track section is aligned with one of the storage tracks and the carriage is then moved onto the storage track and later the moving platform is moved again until the track section is aligned with the storage track and then the carriage is moved onto the track section and the moving platform is moved to the reel stand where the paper reel resting on the carriage can be picked up by the reel stand.
