Definitions

  • the invention relates to a method and an apparatus for transferring a web (consisting of a flexible material), in particular a paper web, from a web-delivering web guide surface to a web conveyor.
  • a threading ribbon which part (e.g. B. edge strips) of the paper web mentioned.
  • the transfer takes place e.g. B. from one first machine section to a subsequent second machine section.
  • Such Machine sections can in particular be parts of a machine for manufacturing 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 paper making machine or inside a winder or from the end of the dryer section the paper making machine to a subsequent calender or to a winding machine. This "ribbon transfer" serves to facilitate threading the paper web into the machine.
  • U.S. Patent No. 3,355,349 describes a vacuum belt conveyor for conveying an insertion strip or ribbon of a paper web from the dryer section of a Paper-making machine for the first nip of the calender of said Machine.
  • the belt conveyor comprises an elongated body and an air-permeable one endless belt that is movably mounted on the body with the help of two rollers is.
  • the endless belt comprises a conveyor strand; that is e.g. his upper run; the The conveyor run runs from the area of the last drying cylinder to the area of the first Nip of the calender.
  • the tape is arranged so that it is the lead strip from the last drying cylinder.
  • the elongated body is formed as a vacuum box, which has a perforated upper part. The vacuum box extends lengthways below the conveyor run of the belt. Measures for generating negative pressure in the box are provided this will keep the leader on the running belt.
  • a separator or ribbon cutter attached, comprising a tooth knife which extends in the transverse direction, i.e. parallel to the roller axis.
  • the belt conveyor type which is known from US'349 and from the said brochure has proven itself in operation. However, improvements are desirable with the goal of making the belt conveyor even more reliable, even at increased working speeds is working. A ribbon scraper should also be avoided because this impermissible wear on the outer surface of the drying cylinder causes.
  • US'643 is a device for cross cutting and guiding a ribbon formed such that they have moving parts and a cutting blade or knife avoids.
  • the ribbon is removed from the last drying cylinder with the help of two edge blowing nozzles detached and with the help of two pneumatic guide plates, which pull the ribbon in two different directions, cut across. Onward transport The strap is then made exclusively with one of the pneumatic ones Guide plates. It is doubtful whether this known design works satisfactorily, at least if a paper web with relatively high strength and / or very high Working speed should be transferred.
  • edge nozzles see, for example, US Pat. No. 1,688,267, FIG. 4, numbers 80 and 82
  • the edge nozzles not only for detaching the paper web, in particular the ribbon from the can use web-emitting web guide surface, but also in addition to Cross-cutting the web or ribbon. This succeeds on the condition that the edge nozzles only for a short time (i.e. if possible only for a fraction of a Second) eject a high-energy jet of air, its flow velocity is as high as possible.
  • the inventive device (claim 5) is suitable for performing the new method defined in claim 1.
  • the device is located at the inlet area, for example of a known vacuum belt conveyor or a rope conveyor (i.e., a known rope guide system) an assembly is provided which is specially designed for the safe transfer of the web or of the ribbon from the web-delivering web guide surface.
  • a known vacuum belt conveyor or a rope conveyor i.e., a known rope guide system
  • an assembly which is specially designed for the safe transfer of the web or of the ribbon from the web-delivering web guide surface.
  • this assembly belongs to a pneumatic guide plate with facilities for generating an air flow running on the guide plate in the direction of web travel.
  • the assembly for cross-cutting the web or ribbon includes one Detaching 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 it is brief a high-energy jet of air is expelled between the web-releasing ones Web guiding surface and the web or the ribbon, so that the web or the ribbon is cut transversely immediately when detached from the web guide surface.
  • the mentioned assembly (consisting of guide plate and separation device) for example relative to the vacuum belt conveyor so that the Distance between the web-guiding surface and the mentioned Assembly may vary.
  • This allows the assembly to be inserted during the threading process temporarily at a very short distance from the web Position the web guide surface. So you can fill the gap between the web releasing Reduce the web guide area and the web conveyor device so that the sag of the web or ribbon during the threading process if possible is largely reduced.
  • you can do the assembly mentioned in one Position a certain distance from the web-dispensing roller or cylinder. This allows the web or the ribbon to run down freely (e.g. in a broke remover), so that blockages and / or damage to the Web conveyor device can be avoided.
  • the assembly consisting of guide plate and separating device can for the safest possible transfer of the new start of the web or ribbon can be further developed as follows:
  • One can directly on the inlet side Provide additional blowing openings at the end of the guide plate to produce one air flow supporting the web or the ribbon.
  • These additional Blow openings should preferably be at the same time as the edge blowing nozzles eject brief high-energy air jets or an appropriate air curtain.
  • the guide plate should be on its inlet side End a so-called Coanda nozzle, i.e. H. have rounded edges that - using the Coanda effect - an air flow (of the highest possible speed) deflected towards the guide plate.
  • the guide plate is cascade-like several has further blowing devices arranged one behind the other, can at least one of these further blowing devices can be designed as a Coanda nozzle.
  • the guide plate on its outlet side e.g. B. located near the conveyor run of the belt conveyor End an air duct that is curved so that it extends from the Path of the train or ribbon removed.
  • This air guide channel does two things: you ensures a deflection of the air boundary layer carried by the belt and power thus harmless; d. H. it is ensured that at most part of this Air boundary layer reaches the point where the ribbon is captured by the vacuum belt conveyor becomes.
  • the air flow brought up on the guide plate is increased the shortest route to the suction zone of the vacuum belt conveyor and for the most part vacuumed there. As a result, the web or ribbon from the vacuum belt conveyor securely recorded and forwarded as intended. It works in a similar way Air channel when the ribbon is passed into the rope shears of a rope guide system becomes.
  • Figure 1 you can see a vacuum or vacuum belt conveyor 8, the Transporting a running web, preferably a threading belt 9, from the last drying cylinder 6 of a paper making machine, for example to a multi-roll smoothing unit 7.
  • a threading belt is known Part of a running web, for example a paper or cardboard web: it is needed for threading the web into the paper making or finishing machine.
  • the web runs on path 9a (FIGS. 1 and 2) downwards, by means of a machine-wide scraper 18 from the cylinder 6 is led into a reject chest (not shown).
  • the vacuum belt conveyor 8 comprises an air-permeable, endless conveyor belt 10, the two rollers 11, 12 and a suction box or vacuum box 15 is running.
  • the two rollers 11, 12 are rotatably arranged in holders (not shown), which are attached to the suction box 15.
  • a vacuum source 17 is indicated schematically for generating negative pressure in the suction box 15.
  • the conveyor run of the conveyor belt 10, which runs in the web running direction, is in the present Trap the upper run; a reverse arrangement is also possible.
  • the Suction box 15 has a cover plate 16, in which slots (or similar openings) are provided are.
  • the conveyor run of the air-permeable conveyor belt slides on this plate 10; as a result, the threading band 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) is provided.
  • the band 9 is widened in a known manner; the complete path, designated in Figures 1 and 2 with 9 ', then runs from cylinder 6 over the Paper guide rollers 13 and 14 on the top roller 7 'of the smoothing unit 7.
  • the suction box 15 is shaped (in a known manner) as an elongated body.
  • Other types e.g. an internal device for generating a vacuum on the conveyor strand of the band 10 can also be used.
  • this includes a pneumatic guide plate 22 and a low pressure chamber, 24 which is connected to a compressed air source 26 via a line 25, furthermore a Ribbon separating device 21 in the form of two so-called edge nozzles. Every edge nozzle 21 is arranged in operation in one of the edge areas of the band 9, see Figure 2A.
  • Each edge nozzle 21 is suitable for applying a high-energy air jet to eject the web-emitting lateral surface 6a of the cylinder 6. This will achieved that the downward-running band 9 from the cylinder surface 6a is detached and that at the same time the ribbon is cut transversely. From now on the ribbon 9 runs with a new beginning of the ribbon over the guide plate 22 Conveyor belt 10 and with this in the direction of the calender 7.
  • the width is b (order of magnitude) 0.2 m) of the band 9 only a fraction of the usual width of the produced or paper web to be refined. It is understood that the working width of the entire web conveyor is adapted to the band width b. However it is also conceivable in a relatively narrow paper processing machine an inventive Machine-wide transfer device.
  • the guide plate 22 In the rest position of the assembly 20, the guide plate 22 is approximately parallel to the belt conveyor 8; the distance between the cylindrical surface 6a and the edge nozzles 21 many times larger than in the working position. If necessary you can also temporarily the assembly 20 in a medium, between the Place the resting and working position in the intended intermediate position. Furthermore, a (not shown) pivoting device can be provided to the Overall device (belt conveyor 8 with assembly 20) from the area of the machine swing out.
  • edge nozzles 21 are preferably immovable in the assembly 20 attached. However, it is also conceivable that the edge nozzles relative to the guide plate 22 are movable.
  • the assembly 20 comprises a high-pressure chamber 34, to which both edge nozzles 21 are connected are ( Figures 2 and 3).
  • the high pressure chamber 34 is via a high pressure line 36 can be connected to a high pressure source 35.
  • a control valve 37 provided that by means of a time signal (line 38) briefly, for. B. for 0.05 to 0.5 seconds, can be opened. It is important that the edge nozzles 21 den Only emit high-energy air jet for a short time, so that the new beginning of the band 9 continues as far as possible without damage. To further reduce the ejection time, you can assign each edge nozzle its own control valve (Fig.
  • the edge nozzles 21 can be C-shaped with one another Form pipe section 40 or 41 (into which the high pressure line 36 opens) z. B. according to Figures 4 or 5. If you have a particularly high at the edge nozzles Air outlet speed (e.g. supersonic speed) is required, the Form edge nozzles as Laval nozzles (21A, Fig. 6).
