Definitions

  • the invention relates to the handling of web rolls, particularly to the handling of web rolls in connection with slitter-winders of fibre-web machines, such as in connection with slitter-winders of paper and board machines, and more particularly to the handling of partial web rolls i.e. customer rolls.
  • the invention relates to an arrangement in the handling of web rolls according to the preamble of claim 1.
  • paper is manufactured in machines which together constitute a paper-manufacturing line which can be hundreds of metres 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 metres.
  • 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 metres 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. This periodicity is tend to be done with efficiency as good as possible in order not to waste already done work.
  • the parent roll web 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.
  • a slitter-winder Of prior art are known different types of slitter-winders, in carrier-roll slitter-winders the web roll is wound supported by two carrier rolls and in multistation winders the web roll is wound supported of its centre.
  • 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 web rolls i.e. the so-called set is removed from the machine. 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 winding of a new parent roll.
  • attaching a tail of the web roll i.e. a tail part of the web remaining on the surface of the wound web roll can be performed by applying adhesive or tape.
  • the adhesive or tape can be attached in the travel direction or cross direction of the web.
  • tail-attaching station It is known of prior art to arrange into connection with the slitter-winder a separate tail-attaching station by means of which the tail of the web roll is attached on the surface of the web roll.
  • a tail-attaching station is heavy of its apparatus requiring a rotating station of the web roll with its rolls, receiving means of the web roll and removing means of the web roll.
  • the station requires a separate movable beam where the taping or adhesion device is attached. Additionally, a frame structure of the beam is required.
  • EP 0754640 is disclosed an arrangement in the handling of web rolls, particularly in the handling of partial web rolls in connection with slitter-winders of fibre-web machines, such as paper and board machines, for attaching a tail of the web roll and a transfer surface which is inclined descending from the slitter-winder towards a plane of the floor level of the machine hall.
  • WO 2011/076997 is disclosed an apparatus in slitter winder for bring a fastening means onto the surface of each partial web, which apparatus comprises an applicator head, which is arranged to apply the fastening means onto the surface of the web and support members, by means of which the apparatus can be mounted into the slitter winder and by means of which support members the apparatus for bringing the fastening means can be arranged movably substantially in cross-section with respect to the slitter winder.
  • the object of the invention is to provide a novel arrangement in the handling of web rolls in which the above-described problems and disadvantages have been eliminated or at least minimised.
  • a particular object of the invention is to create an arrangement in the handling of web rolls, particularly partial web rolls, in connection with slitter-winders of fibre-web machines where, in connection with the slitter-winder, no separate tail-attaching station is required.
  • a web roll completed on a slitter-winder is pushed from carrier rolls of the slitter-winder onto a transfer surface of the arrangement which is located such that the transfer surface is in an inclined position descending from a plane of the substantial upper surface of the carrier rolls of the slitter-winder towards a plane formed by the floor surface of the machine hall.
  • a receiving beam for receiving the web roll.
  • the receiving beam comprises rotating rolls or a sliding surface on which the web roll supports itself when contacting the receiving beam.
  • the receiving beam comprises transfer means and an actuator, by which the position of the web roll is descended on the transfer surface controllably downwards such that the web tail of the web roll is at a desired point for attaching the end.
  • tail-attaching means by which the tail is attached on the surface of the web roll.
  • the receiving beam When the tail has been attached to the web roll, the receiving beam is transferred away from the web roll in the machine direction or the vertical direction and the web roll transfers along the transfer surface e.g. to a roll receiver or on the floor, from where the web roll is typically transferred onto a conveyor.
  • the receiving beam can also transfer downwards parallel with the transfer surface supporting the web roll to accompany it to a receiver i.e. a tipper or on the floor or so far as the conveyor.
  • the web roll is then pushed from the carrier rolls of the slitter-winder onto a table having a downward slope.
  • the web roll is received by the receiving beam which has rotating rolls or a sliding surface.
  • the web roll is descended controllably downwards until the web end i.e. the tail end is at a desired point.
  • the web roll is stopped and the tail attachment is performed with an adhesive material, such as tape or glue, in the machine and/or cross direction.
  • the tail-attaching means are attached to the receiving beam above or below it.
  • the receiving beam is transferred away from the web roll in the machine direction or the vertical direction.
  • the identification of the web tail end is arranged.
  • the identification can be based on calculation or it can be detected e.g. by an observation device based on computer vision or e.g. by photoelectric sensors.
  • the receiving beam of the arrangement has been supported from its both ends being cross-directional in relation to the machine direction on end structures which e.g. move along rails or equivalents arranged on the machine hall floor.
  • the motion of the end structures can be mechanically or programmatically synchronised.
  • the receiving beam is provided with a damping device to damp the contact impact of the web roll.
  • the damping device is e.g. a damper arranged into connection with the end structures.
  • the arrangement according to the invention is simple and reliable in operation enabling the tail attachment of the web roll quickly and smoothly.
  • the arrangement according to the invention is applicable in connection with various fibre-web slitter-winders.
  • the arrangement according to the invention is described in connection with the so-called carrier-roll slitter-winder, in which carrier-roll slitter-winder, the web roll is wound supported by two carrier rolls.
  • the invention is also applicable for use in such slitter-winders where one carrier roll is replaced by a set of belt rolls which consists of e.g. a rotating, endless belt arranged around two belt rolls.
  • the invention is also applicable in connection with the so-called multistation winders where the web roll is wound by rotating means located in the centre of the web roll.
  • the arrangement according to the invention can attach the tails of the web rolls of the whole set.
  • the receiving beam extends advantageously in the cross-machine direction substantially for the longitudinal travel of the whole set in the same way as the rolls supporting the web roll.
  • There can be several tail-attaching devices in the longitudinal direction of the set such that one tail-attaching device attaches the tail of at least one web roll or they can be transversing, whereby the tail-attaching device comprises a control arrangement to direct the application of the adhesive material always at the point of each web roll.
  • the tail-attaching device can also extend in the longitudinal area of the whole set adding the adhesive material for attaching all tails of the web rolls of the set substantially simultaneously.
