Definitions

  • the invention relates to a roll changer for a web-processing or processing machine, which is set up for a roll change at standstill of the roll changer.
  • the invention further relates to a method for an automatic reel change in such a machine, in which a web to be replaced, although retracted into the machine, but is not in production.
  • Such reel changers are eg from the DE 1256501 , of the US 5,514,237 , of the US 5,064,488 and the US 4,892,263 known.
  • Web-fed rotary printing machines which are preferred examples of web-processing machines for the purposes of the invention, usually have reelstands which are capable of carrying out a so-called flying reel change.
  • a unwinding in the reel splitter from a work roll working web is fully automatically added in a flying reel change during production a stock web and connected to the work path.
  • the supply track winds in the roll changer from a supply roll.
  • the work path is cut, and the old work role either also fully automatically or manually taken from the reel changer and replaced, for example, against a new supply roll.
  • the supply track attached to the working track is the new working track.
  • reelstands that are set up for a flying reel change are standard, at least for large newspaper presses, the reel change causes problems when the reelstand is at a standstill.
  • no reel changers are known which are set up both for a flying reel change and for a fully automatic reel change when the reel changer is at a standstill.
  • the invention is based on a reel splicer for a web processing machine, which is set up for processing a work web to be processed from a work roll, attaching a supply web to the work web and connecting the two webs to one another.
  • a preferred example of a web-processing machine is a web-fed rotary printing press, preferably an offset press for newspaper printing, especially newspaper printing in large runs.
  • the machine may also be a web-processing machine for plastic or metal and basically any web-like material, for example a plastic film, a metal foil, but more preferably paper.
  • the one web is referred to, which is already fed into the machine and is to be replaced by the supply track, for example, according to consumption.
  • the reel changer has a first storage for the work roll and a second storage for the supply roll.
  • the bearings are preferably movable in the reel changer so that they are movable in alternation in a working position and in an exchange position.
  • the working position advantageously also forms a joining position, which is an adhesive position when joined by gluing.
  • the bearings are formed by roller arms, which are pivotable alternately in the working position and in the replacement position.
  • the roll changer further comprises a connecting device for connecting the supply web with the working web.
  • the connecting device is preferably designed as an adhesive device in order to produce an adhesive bond between the working web and the supply web. This is the usual connection technology for webs in web-fed rotary printing. In machines for processing or processing plastic films, however, the connecting device can also be formed, for example, by a welding device; also in machines for the treatment or processing of metallic webs. However, other suitable joining techniques should also not be excluded, even for paper webs.
  • the roll changer further comprises a holding device, which in the conveying direction of the working path behind the connecting device, i. down the connection device is arranged.
  • the holding device is designed such that it can fix, preferably completely block, the working path in relation to the conveying direction.
  • the fixation is preferably carried out exclusively by frictional engagement, particularly preferably by clamping the work path.
  • the reel changer finally includes a draw gear for the work path.
  • the traction device is arranged in the path of the work path between the connecting device and the holding device and set up or designed so that it can pull the working web from the work roll.
  • the removal from the work roll is either entirely without engine assistance or with engine assistance or even against a braking force that may be generated by a drive motor or an additional brake.
  • an advantageous web tension is generated and maintained by means of the pulling device, optionally in conjunction with a rotary drive of the work roll or a brake for the work roll, during the peeling.
  • the traction device may be a traction device with which the web is also conveyed during ongoing production
  • the trajectory is preferably conveyed by the traction device only when the reelstand is at a standstill, but this length must of course be sufficiently great establish the connection of the supply track with the work path and the automatic roll change with fixed work path to carry out. If the towing device promotes the web in the current production, this is preferably done only temporarily.
  • a particularly elegant solution is the use of a clamping device, which serves to compensate for web tension fluctuations during ongoing production of the machine, as a pulling device.
  • known web tension devices such as pivotally or linearly movably mounted pendulum rollers and equivalent roller devices, which are wrapped by the web and regulate by their own movement transversely to its longitudinal axis, the web tension by changing the length of the web path.

  • the web start of the supply roll should be replaced by the withdrawal from the supply roll.
  • the holding device must therefore fix the web at least in the sense that the working web is not pulled out of the machine in the direction of the roll changer by means of the pulling device, while a withdrawal or withdrawal of the working web from the work roll does not take place to a sufficient extent.
  • the holding device can in particular be formed by a draw roller or a plurality of draw rollers, which are or are arranged in the path of the work path in front of the first printing unit, in particular by an infeed mechanism for the printing unit or several printing units.
  • a tension roller or the plurality of tension rollers is set, i. the tension roller or tension rollers is or are preferably blockable. If the coefficient of friction between the web and such a tension roller or a plurality of tension rollers is already sufficient for a fixation of the web, an already existing traction device can directly form the holding device according to the invention.
