Definitions
- the invention relates to a vacuum belt conveyor device with the in the preamble of Claim 1 specified features.
- Vacuum belt conveyors used to facilitate threading a paper web into a machine for the production or refinement or further processing of such a web.
- a paper production machine or when restarting after a web break
- This band is made using the vacuum belt conveyor for example from the end of a machine section to the entry area of a subsequent one Machine section transferred.
- German utility model 299 10 850 describes a vacuum belt conveyor device which comprises an air-permeable endless belt which runs over two rollers and a vacuum box.
- the negative pressure of the negative pressure box propagates through the conveying run of the belt in order to suck in a web or a band which is to be guided by means of the conveyor belt.
- One of the rollers can be moved to tension the belt.
- An object of the present invention is to provide an improved conveyor to create that works reliably with different types of paper, also for paper types with high tensile strength and also in modern paper manufacturing or finishing machines with extremely high working speeds (for example over 2000 m / min.)
- Another object of the invention is on the roller delivering the web or cylinder to make a ribbon scraper superfluous. Likewise, the Avoid using a ribbon cutter and a feed plate.
- Another object of the invention is an improved construction which allows the upstream end of the conveyor closer than before to the one emitting the web To arrange surface (for example surface of a roller or a cylinder).
- a belt conveyor device (with the in Preamble of claim 1 specified features) additionally a curved and perforated guide surface for the air permeable endless belt; this leadership area is located at the upstream end of the conveyor; the Perforations of the guide surface are open to the endless belt, also open inward towards a negative pressure source.
- the curved and perforated guide surface acts as one Pickup suction zone, for example, which can be placed very close to the path of the track close to a surface giving off the web (sieve or felt or Roller or cylinder). This will make the web or ribbon, especially a new one Beginning of the ribbon, in a much shorter time than before on the conveyor belt transferred.
- the pickup suction zone of the vacuum belt conveyor touch the path of the web directly, so that the ribbon, especially a new beginning of the band can be transferred directly to the conveyor belt can.
- the band preferably a new beginning of the band, from this surface detached, namely by means of at least one edge blowing nozzle.
- the ribbon is gripped by the conveyor belt, in the region of the curved one and perforated guide surface.
- the new beginning of the ribbon is upstream at a short distance the (preferably two) edge blowing nozzles is formed.
- the vacuum belt conveyor device 8 shown in FIGS. 1 and 2 comprises one first roller 11 located at the upstream end of the conveyor. An air permeable endless belt and the downstream end of the conveyor (including a second role) are not shown.
- the first roller 11 has a perforated jacket 13 and is supported by two end shields 14 supports rigidly with the upstream section 15a of a vacuum box 15 are connected.
- This vacuum box 15 is divided into the above upstream section 15a and into a downstream section 15b.
- the upstream section 15a of the vacuum box 15 is perforated Coat 13 of the first role open. Seals 16 and 17 are between the jacket 13 and section 15a are provided.
- a negative pressure upstream section 15a (for example, by the section 15a via a vacuum inlet to a vacuum source, not shown is connected).
- the negative pressure will then go through those perforations of the jacket 13, which are not currently covered by the tape, into the interior of the Propagate roll 11 and from there through the other perforations of the casing 13 and through the breathable band. This will make the tape (by suction) capture a web or a ribbon 9 (which is to be transported) earlier than in a conventional vacuum belt conveyor that only has closed rollers having.
- the upstream section 15a is also provided with a cover plate 22 ceramic or other low-friction material), wherein suction slots 23 are provided, which are (preferably) parallel to the tape running direction extend.
- a thin perforated film (or "runner” 24) is connected to the plate 22, made of stainless steel, for example; the runner 24 is on the Slide cover plate 20 when the tape will be tensioned.
- the negative pressure prevailing in the upstream section 15a should preferably be be higher than the negative pressure prevailing in the downstream section 15b.
- Various external or internal vacuum sources can be used; such are described in the as yet unpublished patent application DE 100 09 188.
- the vacuum belt conveyor shown in Fig. 3 includes an air permeable endless belt 10, a first roller 11, a second roller 12 and a vacuum box 25.
- a web or a ribbon that is to be transported is designated by 9.
- the first roller 11 is a suction roller with a perforated rotatable one Sheath 13 formed.
- the vacuum box 25 formed as a one-piece stationary component that a cover plate 20 with has the usual suction openings 21.
- the vacuum box 25 carries both first roller 11 as well as the second roller 12. The latter is for tensioning the tape 10 displaceable, the first roller is not displaceable relative to the vacuum box 25.
- the vacuum box 25 is open towards the rotatable jacket 13. In turn seals 16, 17 are provided.
- the negative pressure generated within the box 25 plants into the first roll 11 and continues through the band 10, so that the Band 9 earlier than before, namely already on the circumference of the suction roller 11, by suction is forced to conform to the band 10. If necessary can the interior of the vacuum box 25 divided by an intermediate wall 26 be so that you have a higher vacuum in the area of the suction roller 11 can provide.
- Fig. 4 shows a further modification of the vacuum belt conveyor device described above. This is similar to the conventional conveyor devices Band 10 over two normal closed rollers 11a and 12, made of one piece Vacuum box 35 are worn.
- the conveyor device for the belt 10 is a stationary, convexly curved and perforated guide surface 32.
- This curved guide surface 32 forms a curved suction zone, which serves the same purpose as the suction roller 11 1 to 3.
- the curved guide surface 32 is curved, for example, by a perforated one Plate 33 formed.
- This can be an integral part of the flat cover plate 20a of the box 35 or it can be separate from this cover plate 20a, which in in any case arranged somewhat obliquely relative to the returning run of the tape is.
- the vacuum box 35 may include or a box section 34 wear which box section envelops a part of the first roll 11a and the mentioned curved perforated plate 33 carries.
- FIG. 5 shows some details of a papermaking machine, namely one last drying cylinder 40, a drying felt 41, a felt guide roller 42, a paper guide roller 43 and a scraper 44.
- the normal running distance of the paper web is with 9A.
- the web runs down at 9B; a band 9 (at arrow 45) is separated from web 9B, from cylinder 40 detached by means of one or two edge blowing nozzles 46 (see FIG. 2) and immediately by one first vacuum belt conveyor 8 detected.
- This conveyor transports the belt 9 to a second belt conveyor 8 '; at least the first Conveyor is designed in accordance with the present invention.
- Fig. 6 shows a vacuum belt conveyor 8A, which in turn according to the Invention is formed.
- a felt or screen 49 which carries a running paper web 9D.
- This path is directly through contact with the belt of the conveyor 8A transferred.
- the lower band run is the transporting run.
