Definitions

  • Document (1) shows a winding machine with a central support roller and with (two) outer carrier rollers arranged on both sides of the same.
  • the three Carrier rollers form two winding beds for winding a plurality of Rolls of paper that are made from longitudinally cut partial webs.
  • Role change is carried out as follows:
  • a separator is swung into the first changing bed from below. This is done here Cutting the partial web (s) in that the paper roll (s) from the Changing bed is or will be ejected into a drain table.
  • the second The paper roll (s) located in the changing bed is or are first placed in a Ejected discharge table, after which one sunk in this discharge table arranged separator is brought into its working position. The Cutting takes place here e.g. by lowering the drain table.
  • Document (2) shows and describes a method and a winding machine, which unwinds the paper web from a supply roll and into one Backup roller is guided.
  • the backup roller has a perforated roller jacket and is vacuumable.
  • the paper web wraps around the support roller on one part of their scope. It is at a certain point in the scope of the Back-up roller wound onto a winding tube to form a paper roll. Is a The roll is completely wound, so it becomes the first one running transversely to the running direction Glue track applied to the paper web. Seen in the running direction a perforation is applied to this glue track, through which the web is weakened, and again, subsequently, another crosswise Traces of glue applied on the paper web.
  • the incoming web e.g. by slowing down the supply roll
  • the incoming web jerkily slows down and thereby at the Zone of weakness severed.
  • the first glue track in the running direction serves the resulting web end to the last layer of the finished roll and the second glue track (seen in the direction of travel) serves to the beginning of the path of the now following path to a new winding tube to stick.
  • the web is not in the weakened zone tears off, but in front of it, e.g. in an area where the web is clear of Supports running.
  • the subject of the document (3) is one across the entire Web width traversable weakening element during a standstill the machine against the web resting on a support roller in order to to squeeze the web and thereby weaken it. This traverse movement takes a relatively long time. There is also a risk of Damage to the surface of the backup roller. The complete cut is then done by increasing the web tension.
  • the document (6) shows a method and a device for changing of winding rolls in machines for winding material webs, especially paper or cardboard webs on cores.
  • Winding rolls become double-sided adhesive strips on the web upset.
  • the adhesive strips are first placed against the web movable transfer element (transfer roller) with less adhesion than applied the material web, then the transfer element (Transfer roller) moved against the web and the adhesive strips to it to hand over.
  • the invention has for its object a method and an apparatus according to the preambles of the independent claims, with what operational safety during the phase of the roll change - despite automatic process as fast as possible - can be increased.
  • the finished roll (s) should be behind the glue point have the shortest possible free web end.
  • the inventor has recognized that the cause of known in Defects (according to documents 2 or 3) is that the backup roller after cutting the web under the essentially at a standstill new web start continues and at the Paper web grinds. Thereby prevail between the lateral surface of the Backup roller and the web after severing undefined conditions, and the web runs sideways.
  • the characterizing part of claim 1 specified method steps or those in the characterizing part of claim 13 specified device features provided.
  • the invention can be different in several winding machines Apply type. Among them are winding machines that only one Back-up roller have (see document (2), Fig. 1), as well as winding machines two or three support rollers, which form one or two changing beds in pairs. In the latter case, the weight in the A roll of compressed air is created in the changing bed being constructed. This includes one from below between two Retractable seal assembly required for rollers (claims 16-18).
  • the arrangement and design of such a sealing arrangement is - thanks to the method of severing the paper web according to the invention when changing roles - much easier, because the from publication (1) known (and can be inserted from bottom to top between two support rollers) Separating device is no longer required. So far has the necessary Consideration of this separator often creates difficulties.
  • Preferred application of the invention are winding machines (with or without longitudinal cutting device), the "off-line", that is isolated from one Papermaking machine operated.
  • Machine speed of the winding machine is generally higher than that of the paper making machine. This usually makes it necessary, according to claim 1, the machine speed for the Changing roles (i.e. temporarily) towards a crawling speed to reduce.
  • the method according to the invention can have the features of claims 2 to 12 are further developed.
  • To further increase the Operational safety during the phase change phase can be done Working speed of the winding machine after reaching the Gradually reduce the creep speed even further (claim 2).
  • it is beneficial if you keep the work speed during the ejection of the rollers to zero or almost zero. If however, it is desired that the entire roll change operations be carried out in run for a particularly short time, then you can - as long as the Weakened and the adhesive is applied - the Keep creep speed substantially constant (claim 3). Also during the ejection of the roll (s) you can use the winding machine if necessary, let it run slowly (claim 4).
  • the ejection of the roll (s) is preferably first (according to claim 5) then trigger when the adhesive traces have reached the roller (s) so that the intended web end is glued to the roll. It deviates from this however, it is also possible to eject the roll (s) shortly before trigger, so that the sticking of the web end during the ejection process takes place (claim 6).
  • Claims 7 and 8 relate to different configurations of the method according to the invention a winding machine with two support rollers.
  • Claims 9 and 10 relate to special configurations of the method for a Winding machine with three support rollers. A modification for a machine with only a single support roller is specified in claim 11.
  • Claim 12 states that the The weakening point must immediately follow the traces of adhesive. It is it is basically irrelevant whether the application of the adhesive before or after or at the same time as the weakening point is incorporated. However, the adhesive dispenser (with regard to the Arrange web direction) behind the weakening device so that a Contamination of the weakening device with adhesive is avoided.
