Definitions

  • the invention relates to a device for transferring a (consisting of a flexible material) web, in particular paper web, from a web-issuing web guide surface to a web conveyor. In most cases, it involves the transfer of a threading strip which is a part (eg edge strip) of said paper web. The transfer takes place z. From a first machine section to a subsequent second machine section. Such machine sections may in particular be parts of a machine for producing or finishing a paper web. For example, it is the transfer of the ribbon inside or at the end of the press section of a papermaking machine or within a winding machine or from the end of the dryer section of the papermaking machine to a subsequent calender or to a winding machine. This "Bändelüberext" serves to facilitate the threading of the paper web into the machine.
  • US Pat. No. 3,355,349 describes a vacuum belt conveyor for conveying an insert strip or ribbon of a paper web from the dryer section of a paper web Papermaking machine for the first nip of the calender of said machine.
  • the belt conveyor comprises an elongated body and an air-permeable endless belt which is movably mounted on the body by means of two rollers.
  • the endless belt comprises a conveyor belt; that is, for example, his upper strand; the conveyor run runs from the area of the last drying cylinder to the area of the first nip of the calender.
  • the band is arranged to receive the lead-in strip from the last drying cylinder.
  • Said elongate body is formed as a vacuum box having a perforated top. The vacuum box extends lengthwise below the conveyor run of the belt. Provided are measures for generating negative pressure in the box, thereby holding the lead-in strip on the moving belt.
  • a separator or belt cutter Attached to the upstream end of the known belt conveyor is a separator or belt cutter comprising a cutter blade extending transversely, i. parallel to the roller axis.
  • the complete web including the ribbon, descends from the last "web-dispensing" drying cylinder, past the infeed area of the belt conveyor, finally entering a broke bin or broke pulper.
  • a narrow "ribbon scraper” is provided on the last drying cylinder to detach the strip from the jacket of the drying cylinder and to transfer the ribbon to the belt conveyor.
  • the ribbon cutter cuts the ribbon and thus forms a new beginning of the ribbon, which is now transported to the calender. If no ribbon cutter were present, the belt conveyor would pull a piece of the ribbon back out of the reject bin and thus transport a "double ribbon”; that would cause problems during the threading process.
  • the belt conveyor type which is known from US'349 and from said brochure, has proven itself in operation. However, improvements are desirable with the aim of making the belt conveyor even more reliable, even at increased operating speeds. In addition, a ribbon scraper should be avoided because caused this undue wear of the outer surface of the drying cylinder.
  • a device for transversely severing and guiding a ribbon is designed to avoid moving parts and a cutting blade or knife.
  • the tape is removed from the last drying cylinder with the help of two edge blowing nozzles and cut transversely with the aid of two pneumatic guide plates, which pull the tape in two different directions.
  • the further transport of the strip is then carried out exclusively with one of the pneumatic guide plates. It is doubtful whether this known type works satisfactorily, at least when a paper web with relatively high strength and / or very high operating speed is to be transferred.
  • edge nozzles see, for example, US Patent 1,688,267, Fig. 4, paragraphs 80 and 82
  • the ribbon can use from the web-issuing web guide surface, but also for cross-cutting the web or the ribbon.
  • the peripheral nozzles emit a high-energy air jet for a short time only (that is, if possible only for a fraction of a second) whose flow velocity is as high as possible.
  • an assembly is provided at the inlet region, for example, a known vacuum belt conveyor, specifically for safe transfer of the web or the ribbon is used by the web-issuing web guide surface.
  • a pneumatic guide plate with means for generating a running on the guide plate in the web running air flow.
  • the subassembly for transversely severing the web or the ribbon comprises a release and separating device which is designed as at least one edge nozzle.
  • the air supply to the at least one edge nozzle is designed such that a high-energy air jet is ejected for a short time between the web-issuing web guide surface and the web or the ribbon so that the web or ribbon is severed transversely as it is being detached from the web guide surface.
  • An important further aspect of the invention is that one makes the said assembly (consisting of guide plate and separator) relative to the vacuum belt conveyor such that one can vary the distance between the web-emitting web guide surface and the said assembly.
  • Said consisting of guide plate and separator assembly can for the safest possible transfer of the new beginning of the web or the ribbon be further designed as follows: It can be provided directly at the inlet end of the guide plate additional blowing openings for generating a transport of the web or the ribbon supportive air flow. These additional blowing apertures should preferably eject short-term high energy air jets or a corresponding air curtain simultaneously with the edge jets. To this end, alternatively or additionally, the guide plate should have at its inlet end a so-called Coanda nozzle, ie rounded edge, which - deflects an air flow (of the highest possible speed) in the direction of the guide plate - using the Coanda effect.
  • Coanda nozzle ie rounded edge
  • the guide plate has a plurality of successively arranged further blowing devices in the manner of a cascade, at least one of these further blowing devices can also be designed as a Coanda nozzle.
  • the guide plate at its outlet side, z. B. located near the conveyor run of the belt conveyor end an air duct, which is curved so that it moves away from the path of the web or the ribbon.
  • This air guide trough causes two things: It ensures a deflection of the entrained air boundary layer of the tape and thus makes them harmless; d. H. It is ensured that at most a part of this air boundary layer reaches the point where the tape is detected by the vacuum belt conveyor.
  • the brought up on the guide plate air flow is passed on the shortest path in the suction zone of the vacuum belt conveyor and largely sucked there. As a result, the web or the belt is reliably detected by the vacuum belt conveyor and forwarded as intended.
  • the air duct when the strip is transferred to the rope scissors of a cable management system.
  • the above-mentioned operations occur at the full operating speed of the papermaking or finishing machine, e.g. At about 2000 m / min, ie within a fraction of a second. Therefore, the invention This is the basis for improved, successful threading processes, especially in modern high-speed paper machines.
  • Figure 1 can be seen a vacuum or vacuum belt conveyor 8, which is used to transport a moving web, preferably a threading-9, namely from the last drying cylinder 6 of a papermaking machine, for example, to a multi-roll calender 7th It is known, a threading-Bändel Part of a moving web, such as a paper or board web: it is needed for threading the web into the papermaking or paper finishing machine. Before the threading operation, the web runs down the path 9a ( Figures 1 and 2), being guided by the cylinder 6 into a broke bin (not shown) by a machine-wide doctor 18.

  • the suction box 15 has a cover plate 16 in which slots (or similar openings) are provided. On this plate slides the conveyor run of the air-permeable conveyor belt 10; As a result, the threading tape 9 is sucked onto the conveyor belt and transported.
  • a so-called nose shoe 50 and a pivotable guide plate 63 (which are known from EP 1 076 130) are provided at the discharge end of the conveyor 8. After a successful threading procedure, the strip 9 is widened in a known manner; the complete web, designated by 9 'in FIGS.
  • the suction box 15 is shaped (in a known manner) as an elongate body. Other types, e.g. have an internal means for generating a negative pressure at the conveyor run of the belt 10 may also be used.

  • Each edge nozzle 21 is arranged in operation in one of the edge regions of the ribbon 9, see Figure 2A.
  • Each edge nozzle 21 is suitable for ejecting a high-energy air jet onto the web-emitting lateral surface 6a of the cylinder 6. This ensures that the downwardly running strip 9 is detached from the cylinder jacket surface 6a and that at the same time the strip is severed transversely.
