Definitions

  • the invention relates to a method for winding fiber webs, particularly for winding longitudinally slitted paper and board webs into partial web rolls, in which method the partial web rolls are wound in winding stations for winding partial web rolls by a nip between a winding roll and the partial web roll being formed.
  • the invention also relates to a device in a winder for winding fiber webs, particularly for winding longitudinally slitted paper and board webs into partial web rolls, in which device comprises winding stations for winding the partial web rolls, which winding stations are formed in connection with a winding roll.
  • a fiber web e.g. paper
  • a fiber web is manufactured in machines which together constitute a paper-manufacturing line which can be hundreds of meters long.
  • Modern paper machines can produce over 450,000 tons of paper per year.
  • the speed of the paper machine can exceed 2,000 m/min and the width of the paper web can be more than 11 meters.
  • a paper web completing in the paper machine is reeled by a reel-up around a reeling shaft i.e. a reel spool into a parent roll the diameter of which can be more than 5 meters and the weight more than 160 tons.
  • the purpose of reeling is to modify the paper web manufactured as planar to a more easily processable form.
  • the continuous process of the paper machine breaks for the first time and shifts into periodic operation.
  • the web of parent roll produced in paper manufacture is full-width and even more than 100 km long so it must be slit into partial webs with suitable width and length for the customers of the paper mill and wound around cores into so-called customer rolls before delivering them from the paper mill.
  • This slitting and winding up of the web takes place as known in an appropriate separate machine i.e. a slitter-winder.
  • the parent roll On the slitter-winder, the parent roll is unwound, the wide web is slit on the slitting section into several narrower partial webs which are wound up on the winding section around winding cores, such as spools, into customer rolls.
  • the slitter-winder is stopped and the wound rolls i.e. the so-called set is removed from the machine and new cores for new partial web rolls are to be transferred to winding stations for winding a new set of partial web rolls. Then, the process is continued with the winding of a new set. These steps are repeated periodically until paper runs out of the parent roll, whereby a parent roll change is performed and the operation starts again as the unwinding of a new parent roll.
  • Slitter-winders employ winding devices of different types depending on, inter alia, on the type of the fiber web being wound.
  • the web On slitter-winders of the multistation winder type, the web is guided from the unwinding via guide rolls to the slitting section where the web is slit into partial webs which are further guided to the winding roll/rolls on the winding stations into customer rolls to be wound up onto cores. Adjacent partial webs are wound up on different sides of the winding roll / on different winding rolls.
  • Multistation winders have one to three winding rolls and in them each partial web is wound to a partial web roll in winding stations around cores that have been fed into the winder and often moved to the winding station by using different kinds of gripping means, which usually require complicated structures and actuators for achieving movements and positioning means for each winding station.
  • gripping means usually require complicated structures and actuators for achieving movements and positioning means for each winding station.
  • a winding nip is formed between the winding roll and the partial web roll to be wound.
  • EP patent publication 0258533 is disclosed a prior art arrangement for introducing a winding tube (a winding core) into a winding machine with at least one supporting roller (a winding roll), at least two adjustable winding frames, with mutually opposed spindles receiving the winding tube, and with at least one winding tube gripper pivotable transversely relative to the axis of the supporting roller between a winding tube receiving position and a winding tube delivery position.
  • the prior art arrangement also comprises a tube trough for transferring the tubes into the winding machine which is arranged respectively above a supporting roller in the region of the winding tube receiving position of the winding tube gripper.
  • the winding tubes are fed into the winding machine in one line along the tube trough.
  • One disadvantage in this kind of arrangement is that the tubes have tendency to adhere to each other at their ends, which causes separating problems in picking up by the grippers.
  • An object of the invention is to create a device and a method for winding fiber webs where the problems relating to feeding cores into the winder have been eliminated or at least minimized.
  • An object of the invention is to create a new device and a new method for a winder for winding fiber webs relating to feeding cores into the winder.
  • An object of the invention is to provide a device in a winder and a method for winding fiber webs where the feeding of cores into the winder is reliable and fast.
  • the method according to the invention is mainly characterized by what is presented in the characterizing part of claim 1.
  • the device according to the invention is mainly characterized by what is presented in the characterizing part of claim 5.
  • Advantageous features are defined in depending claims.
  • the partial webs are wound as set into partial web rolls in a multistation type winder which comprises one or two winding rolls
  • the cores are fed into the winder in pairs by a core pusher that pushes two adjacent cores in to the winder simultaneously and positions stepwise the cores to correct locations in the winder to be picked up to the winding stations on the winding rolls.
  • the core pusher may push and locate only one core at time.
  • first two adjacent cores are fed into the winder by the core pusher and one core is positioned for a winding station at one of the two winding rolls, the core pusher moves backwards and is reduced for one core only and the core pusher moves in the feed direction and positions the other core for a winding station on the other of the two winding rolls, the core pusher is reduced for return to be ready for transfer of the next two cores.
  • the device in a winder for winding of partial webs in a multistation type winder which comprises one or two winding rolls and an arrangement for feeding cores with a core pusher for pushing two adjacent cores into the winder simultaneously and for stepwise positioning the cores in the winder to be transferred to the winding stations on the winding rolls.
  • a core storage and batching means for moving the cores from the core storage in to position for the core pusher feeding are located outside of the winder such that the cores for the winding stations at each of the two winding roll are loadable at same location.
  • the cores are pushed into the winder by only one pusher pushing two adjacent cores simultaneously into the winder, which makes the arrangement cost effective and simple.
  • the cores are transferred to the winder such that at the end of the feeding the cores for the set are in the winder for picking up to the winding stations in two adjacent rows at correct locations in respect of the winding stations.
  • the cores are fed into the winder in two rows, or lines by the core pusher and the cores to be fed next will be located for feeding during the feeding of the previous cores from the core storage and thus all cores for a set can be moved to correct locations for winding stations during the winding of the previous set of partial web rolls.
  • the reducers reduce the core pusher for pushing one core only such that the other's location is not disturbed and also reduce the core pusher for movement back for next cores such that the cores waiting to be fed will not be dislocated.
  • a new device and a new method for a winder for winding fiber webs relating to feeding cores into the winder is achieved in which as a result the cores are in line at correct locations for winding stations.

  • the means 27 for expanding the core pusher 21 consists of a V-shaped slot in the expander 20, which also serves as a stopper for the return movement back to waiting position for the pusher 21.
  • the pusher 21 has pushed the cores 31 L, 31 R along the transfer guides 24L, 24R to the location of the first core 31 L for picking up to the winding station.
  • the pusher 21 has backed up to the location of the pusher reducers 23L, 23R and the pusher reducer 23L on the side of the already located first core 31 L is opened to the reducing position such that the reducer actuator 26L is activated.
  • the reducer actuators 26L, 26R consists of actuators, for example pneumatic or hydraulic cylinders.
  • the reducer actuator 26L of the pusher reducer 23L extends crosswise over the transfer guide 24L on its side such that by moving the pusher 21 in return movement the reducer actuator 26L pushes the shoulder 25L into reduced and withdrawn position, in which the shoulder 25L will not contact the end of the core 31 L on its side and the pusher 21 can be moved past the core 31 L without contacting it and without dislocating it.
  • the pusher 21 pushes the other core 31R into correct position for picking up to the winding station and the end of the core 31 R is supported against the shoulder 25R on the transfer guide 24R.
