Definitions
- the invention relates to a method for gluing fibers after the Preamble of claim 1, a plant for carrying out the Method and a Faserbeleimungsvorraum.
- the fibers are glued in a blowpipe, the connecting tube from the refiner to the dryer, or adhesives using various combinations of dry gluing techniques.
- Fiberboard-coated fibers are dried with a one-stage or two-stage dryer from a starting moisture of 30-110% to a target moisture of 5-15%.
- the glued fibers are placed in an air stream of a tube dryer and transported in about 3 seconds to the separator (cyclone) at a speed of 30-80 m / sec, where they are separated from the dryer air in about 3 seconds and from a rotary valve be removed.
- the separator cyclone
- the fibers are added twice to the hot air stream and separated twice from the hot air with a separator.
- the adhesive saving is about the same size in the industrially carried out pipe and mixer gluing process, since the adhesive saving is essentially due to the avoidance of the pre-hardening due to the high dryer inlet temperature.
- Adhesive insert Blowpipe line 1st stage dryer Adhesive insert Blowpipe line 2nd stage dryer Adhesive insert Mixer or raw gluing of known methods Dryer inlet temperature of the air [° C] 180 (exhaust air dryer) 140 (1st level) 135 (2nd level) 50 fiber temperature before gluing Dew point temperature at the end of the dryer [° C] 46 50 (1st level) MDF standard 10-13 8th 7 (some glue spots) MDF deep tilling quality 12 11 Not possible to disturb glue spots
- DE 16 53 223 A describes a method and a device, can be glued with the falling fibers.
- This method describes the separation of the fibers before spraying, the spraying the fibers in free fall from the side and a resolution of the fibers or of Fiber agglomerations after spraying.
- the fibers should be in front of the Spraying be separated by means of putting in rotation and over a Circular movement to enter the free space.
- This method with device could not prevail because the fiber singulation by means of rotation Within a stirrer tends to blockages, the throughputs too low and especially the lateral spraying to an uneven Gluing leads.
- Fibers are said to be in a cylindrical tower fall with a diameter of 1.5 m and a length of 4 m and at Fall off the side with adhesive droplets to be sprayed.
- there Fiber agglomerates - ie over-gluing - are consciously accepted taken.
- the agglomerates in Refinem or Mills dissolved again.
- no adhesive can be saved, as the Fiber distribution over the cross section of the tower and the glue distribution on The fibers are much too uneven when sprayed from the edge. fibers, which are located in the middle of the tower receive very little glue.
- DE 19 04 856 A from which the invention proceeds, is a device for gluing falling fibers.
- This device provides a gluing, in which the gluing nozzles within the descending fiber are installed and the adhesive in the direction of falling fibers is sprayed - a so-called internal gluing.
- the advantages of an internal spraying of the fiber stream in terms of a better uniformity of the adhesive application are recognized.
- the fibers are transported by means of transport air to a discharge head. In the Discharge heads protrude from the wall sheets to about the middle of the head. In these sheets nozzles are installed, which spray the adhesive down.
- the device described therein does not solve the problem of blockages by fibers that settle over the protruding sheets.
- the invention has for its object to provide a method with which it is possible in the blowpipe glued fibers without precuring the To dry adhesive and a device for carrying out the process to accomplish.
- a plant for carrying out the method comprises a blowpipe and a Pipe stream dryer for pre-gluing, a transfer device for the Fibers into a fiber bunker, a conduit and a housing for transfer the fibers in a Bunkeraustrag and therein the arrangement of a Faserbeleimungsvorraum with discharge head for the entry of glued Includes fibers in a classifier or directly in a scattered bunker.
- the Faserbeleimungsvorraum for the inventive method and the inventive system is characterized by the arrangement of several Opening rollers one above the other on several axes of rotation in the bunker discharge, a conveyor of the fibers by guide plates formed locks in a grid opening, wherein the grid opening through the horizontally arranged ends of the guide plates is formed and wherein each housed at the end of each guide plate several glue nozzles are made.
- the fibers are separated in Bunkeraustrag by opening rollers and fall through guide plates directed to a grid opening down, wherein At the end of the guide sheets glue nozzles are attached, which are in the direction of spraying falling fiber.
- By the method according to the invention is for Time of adhesive application ensured that a uniform Distribution of the fibers over the full spray surface in the discharge head is present and that the fibers enter dissolved in the spray zone of the grid opening.
- the fact that the resolution rollers at much higher speed the fibers from the Bunkeraustrag encourage than the conventional bunkers, is one Part of the fibers conveyed horizontally up to a distance of 2 m. That means that Fibers from upper opening rollers are almost to the opposite Wall transported while the fibers from the lower opening rollers less be transported far.
- the fiber throughput should not exceed 30 t, and preferably 2 - 20 t per hour and per m 2 spray surface, so that the fibers do not form a too dense curtain. This ensures that also the fibers, which are located in the middle between two guide plates, are glued.
- the spray cone of the glue nozzles is adjusted so that only a slight overlap of two adjacent spray cone occurs.
- the guide plate spacing is chosen so that the distance from the glue nozzle to the point in the middle of two guide plates is not so great.
- the operating costs of the device are significantly lower than the conventional mixer or Rohrbeleimungs Kunststoffs Kunststoff as an additional Air transport does not have to be carried out. Likewise, the Investment costs significantly lower than with conventional methods. If the integration into an existing scatter bin is done additional machines necessary. Also, no disturbing Formaldehyde emissions in the exhaust air. Surprisingly, it has become also pointed out that the glue spots as good as no longer exist when some of the adhesive is previously in the blowpipe line on the fibers is applied. In a combined gluing of Blasrohrline and Dry gluing should not be used to further reduce the adhesion of the fibers Temperatures above 110 ° C are dried. This can be a 3- or Multi-stage dryer used to reduce inlet temperatures become.
- the device according to the invention can be used directly as a scattering bin over the Spreading head or over a conveyor belt which leads the fibers to the spreading head, or installed in front of the classifier or in front of the spreading bunker. If the Fibers are not yet spotted and should be dried, the Installation in front of the sifter.
- Agglomerations form after gluing by moving the fibers with each other and in contact with the walls (pipes especially at Transportation in pipelines and warehouses in the bunker (in the bunker only at the Exterior wall).
- the agglomerations are later than glue spots in the plates to see. These agglomerations are particularly intense immediately in the first 2 - 10 seconds after gluing, when glue is applied to the Fibers have not dried yet.
- the gluing is done directly over the spreading head the should Width of the discharge head of the opening of the maximum spreading width correspond.
- the gluing over the scattering head can form fiber agglomerations after gluing as good as no longer form, because the fibers are no longer transported and with the walls except for the Spillway have no contact. The fibers only have contact with the lateral scattering wall, where agglomerations and thus glue spots form could.
- the agglomeration can but minimized: If the fibers fall on a conveyor belt, the Mat height on the conveyor belt to the spreading head as low as possible be set. The feed rate of the conveyor belt is so adjusted so that the fiber height on the belt is less than 300 mm.
- the wall of the conveyor belt and the scattering wall in front of the Scattering be cooled and / or vibrated and / or with a Air jacket can be provided or on the inside of the wall can be a band run with about the transport speed.
- the Discharge rollers are operated in the scattering head at a higher speed, and with a higher number on the same length (6-10 pieces per 1 m length) and a narrower width, so that agglomeration is not more to get through the scattering head on the forming belt. Even if Despite these measures still small agglomerations on the mat edge This is irrelevant for the later plate, since this Matsrand GmbH first removed over the Matsbeanäumung and / or is then trimmed as a plate edge piece.
- the material recycling of the mat edge trimming, the scalper and the mat return can be guided through a separate fiber opening roller and after the fibers are fed onto the conveyor belt. Then can the conveyor belt will be equipped with recoil rollers.
- a mat scales can be integrated, for dosing the adhesive and for controlling the bunker discharge can be used.
- the fibers should be at least approximately 6 m free immediately after gluing and then into a hot air stream (60 - 80 ° C) passed become. During the fall and in the hot air flow finds one Drying of the freshly glued fibers instead, causing the adhesive something dries and thus less sticky and possibly by the adhesive introduced moisture is reduced.
- the Device also only from a discharge head and a belt conveyor exist, the execution as a bunker is not necessary.
- the width across the The conveying direction can correspond to the classifier width, so that the fibers after the Glueing be transported in the classifier.
- the plant 1 for carrying out the method is shown in Figure 1 and the Faserbeleimungsvoriques 2 in Figures 2 to 7. It comprises a blower tube 17 and a tube flow dryer 20 for pre-gluing, a transfer device for the fibers in a fiber bunker 3, a line 5 and a housing 6 for transferring the fibers into a Bunkeraustrag 4.
- the Faserbeleimungsvorraum 2 consists of a discharge head 14 for the entry of glued fibers in a classifier 16 or directly on the scattering head 19 in a scattering hopper (not shown) and the arrangement of several opening rollers 8 on top of each other on several axes of rotation in Bunkeraustrag 4.
- the grid opening 9 is formed by horizontally arranged ends of the guide plates 11 and each end of each guide plate 11 more glue nozzles 12 are housed.
- Bunkeraustrag 4 at least three, preferably eight opening rollers 8 are provided for separating the fibers in an oblique arrangement one above the other, wherein the fibers are conveyed from the fiber bunker 3 in the Faserbeleimungsvorraum 2 via a belt weigher 7 continuously.
