Definitions

  • the invention relates to a method for wrapping a bundle of hollow fibers in a film tube enveloping the hollow fiber bundle, with a film web around the Hollow thread bundle beaten to form the film tube, cut to length and is connected to itself, and a device for performing this Procedure.
  • Hollow thread bundles are known to be bundles of hollow threads that are other threads can contain, and used for mass and / or heat exchange.
  • the Hollow threads of these bundles are very sensitive to mechanical stress.
  • Around a surface defined for the exchange of material and / or heat via the hollow fibers To make available, the number of hollow threads in the bundle must be precisely defined his.
  • Bundles of this type are used in exchanger apparatuses.
  • the hollow fiber bundles are wrapped in foil to close them protect.
  • the film forms a tube in which the hollow fiber bundle is arranged.
  • this film tube is in usually open at the end faces and loosely envelops the hollow fiber bundle with it the bundle of hollow fibers from the tube over one of the two end faces of the foil tube can be pushed out.
  • the wrapping of the hollow fiber bundle is usually carried out in such a way that the The film is laid out, the hollow fiber bundle is placed on this film and is rolled into the film web to form the film tube.
  • a welding process applied, but it must be avoided that for welding the Foil required temperature not up to the hollow fibers of the hollow fiber bundle penetrates to avoid damage to the hollow fibers.
  • the welding of the Foil is made such that the welding device is parallel to the hollow fiber bundle axis is moved perpendicularly to the formed film tube, whereby a Weld seam with the film layer underneath seen from the outside.
  • Hollow thread bundle required at least one additional layer of the film.
  • some hollow filaments could even be included in the weld be welded in.
  • the film must be in several layers around the Hollow thread bundles are beaten to at least one, the hollow thread bundle Get adjacent location that is not with a more external location is welded.
  • Such layers must be present in such a number that avoid penetration of excessive heat down to the hollow filaments becomes. This makes it clear that the film has at least three layers on the Hollow thread bundle must be wound before welding can take place. Similar problems arise when using the film to form the tube wants to stick, since it must be avoided that individual hollow threads on the film be glued. Other types of connections such. B. Sewing is already ruled out For reasons of economy.
  • the described methods for wrapping hollow fiber bundles have one Series of disadvantages. So it can when rolling the bundle of hollow fibers in the Do not avoid film that individual hollow threads between the layers of the film too come to lie, which later makes it difficult to push out the bundle. It can even such hollow threads are injured. Furthermore, a large amount on film due to the required multi-layer winding required, which the Cover becomes disproportionately expensive. In addition, the multi-layer winding the final inspection of the wrapped hollow fiber bundle made difficult by the film every layer of the film, even with a transparent film, the view of the bundle of hollow fibers is becoming increasingly unclear due to these situations.
  • the object of the invention is achieved by a method for enveloping a hollow fiber bundle into a foil tube enveloping the hollow fiber bundle, wherein a film web around the hollow fiber bundle to form the film tube beaten, cut to length and connected to itself, which is characterized in that the film web is placed around the bundle of hollow fibers in this way is that the film web successively has a first, second and third Has section, the hollow fiber bundle being enveloped by the second section, and the first and third sections are superimposed and from the hollow fiber bundle point away that the first and third sections near the Hollow thread bundle connected to one another and from Hollow thread bundle can be seen from in or behind the composite.
  • the first and third sections can be kept relatively short, so that only slightly more film is required than it is for wrapping the Hollow thread bundle is required.
  • the method according to the invention allows that the second section of the film can be placed relatively loosely around the hollow fiber bundle can, so the place after merging the first and third Section used to connect the first and third sections, one has a small distance to the closest hollow filaments. Because of that and also due to the fact that the connection to the Hollow thread bundle but perpendicular to that through the axis of the Hollow thread bundle leading level, but outside the hollow fiber bundle can be carried out in the method according to the invention significantly more connection types such as welding, gluing, Use sewing, needling, staples etc.
  • the term film is all the flat structures summarized, which are suitable for wrapping hollow fiber bundles.
  • the film can consist of paper. But it can also be from one close mesh, a woven or knitted fabric or the like.
  • the film preferably consists of a film, the material of which is preferably a is thermoplastic polymer.
  • the method according to the invention can be carried out in a particularly simple manner If a film web is spread out, carry out a hollow in the film web is formed to form the second section, a hollow fiber bundle in the hollow is placed, the hollow is formed into a tube which is the bundle of hollow fibers contains, whereby the tube forms the second section of the film web, and if the first is connected to the third section. That way it will Hollow thread bundles to be enveloped are treated with particular care.
  • the film web on a two-part table with a first and a second table top is spread out, the first and / or the second Table top must be placed at a distance from each other, so that a gap is formed, which is at least the same size or larger than the diameter of the is to be wrapped, and that the hollow by inserting the film in the Gap to a depth at least equal to or greater than the diameter of the bundle to be wrapped is formed.
  • the first one is used to form the tube and / or the second table top can be moved towards one another to close a gap form, which is greater than twice the thickness of the film but smaller than that Diameter of the bundle is, after which the first and / or third film section around such a distance is led away from the gap until the second forming the hollow Section loosely envelops the hollow fiber bundle and is formed into a tube.
  • the hollow fiber bundle is loose but so tight that the enveloped bundles of hollow fibers are not readily processed during its further treatment slides out of the shell, encloses.
  • the inventive method can be particularly simple and therefore inexpensive then be carried out when the first and third are used to produce the composite Section are welded together.
  • the first and third sections can preferably be separated during welding so that welding and cutting are carried out simultaneously. Welding processes in which parts of foils are separated at the same time well known and therefore need no further explanation.
  • the object of the invention is also achieved by a device for Implementation of the method according to the invention with a table top, one Feeder for a film web, a device for connecting the film web and a device for separating the film web, which is characterized by that the device has two table tops, the first and / or second Table top for changing the width of a between the first and second table top formed gap towards and away from each other in one with respect to the first table top first and / or a second with respect to the second table top Movement plane are arranged movably, and the second table top Device for feeding the film web is arranged adjacent.
  • the gap between the first and second is first Table top slightly wider than the diameter of the hollow fiber bundle to be wrapped adjusted by moving the movably arranged table tops, thereby on easily formed by pressing down the film into the gap can be in which hollow the bundle of hollow fibers can then be inserted. Then when the movable table tops are moved towards each other is achieved at the same time that the hollow is formed into a tube and the first and third sections of the film are placed on top of each other.
  • the formation of the hollow is particularly successful when above the first and second Tabletop a stamp that can be moved on one level to form the hollow is arranged, which plane an angle between 90 ° and 60 ° to the first and / or second plane of movement and at least approximately centrally through the formed by the first and second table top gap.
  • a preferred embodiment of the device according to the invention is distinguished characterized in that the feed for the film web comprises a stepper motor.
  • the film can be placed on the two table tops be pushed before the hollow is then formed and the bundle is encased. He can also be used to add the third section of the film after Move the two table tops back together so far that the Foil follows the contours of the bundle and at the same time loosely embraces the bundle.
  • the first table top is a device for holding the film web. With this facility, the first section be held while the third section on education via the stepper motor the tube is withdrawn.
  • the welding device also has a device for Separation of the film web is.
  • a device is used to carry out the method according to the invention used, as shown in Figures 1 to 5.
  • a slide 1 is over a connected to the transport rollers 4 and 4 'stepper motor (not shown) by pulled off a film roll 7 so far and pushed in the direction of arrow A that the film 1 to lie on a first table top 2 and a second table top 3 is coming.
  • the direction of rotation of the transport roller 4 is indicated by the arrow B.
  • the first table top 2 and second table top 3 are at a distance from one another arranged, which distance is slightly larger than the diameter of one hollow fiber bundle to be enveloped.
  • Above that by the distance of the first and A second stamp 5 is arranged on the second table top 2 and 3. which has an outer contour that the outer contour of the to be enveloped Hollow thread bundle corresponds. Since the hollow fiber bundle is only needed later this is not shown in Figures 1 and 2.
  • the stamp 5 is now moved down until it is below the table tops 2 and 3 is arranged, with a second section from the film to a Hollow 8 forms as shown in Figure 2.
  • the shape of the hollow can be such take place that first a holder 6 in the direction of arrow D as far down is moved that a first section 1 of the film is held.
  • At the subsequent shutdown of the stamp 5 is a via the stepper motor such a proportion of film supplied that the stamp 5 can form the cavity 8.
  • a hollow fiber bundle 9 is now inserted into the hollow after the stamp 5 has been moved back into the starting position shown in FIG. Then the movably arranged table top 2 is moved in the direction of arrow E and thus also in the direction of the second table top 3 in such a way that only a narrow gap has formed between the first table top 2 and the second table top 3 (see FIG. 3).
  • This gap should only be slightly wider than twice the thickness of the film so that the film can still be pulled through the gap, but not that in the cavity 8 inserted bundle of hollow fibers 9.
  • the film is now in via the transport rollers 4,4 '(direction of rotation according to arrow F)
  • Direction of the film roll 7 (arrow G) to withdraw such a piece that the film in the second section 8 '' 'is loose, but the contour of the hollow fiber bundle 9 then places around the bundle of hollow fibers, as shown in FIG.
