Definitions

  • the present invention relates to a device for laying a fleece from a card web, comprising a transversely to a delivery conveyor belt above the same movable laying carriage and a superstructure and several Flortransportb selected for transporting the card web over the superstructure and the laying carriage in a laying carriage formed Ablegespalt for storage the flag web on the delivery conveyor.
  • a device of this kind is from the EP 0 865 521 B1 known.
  • a nonwoven in which the pile recording has a tape inlet of the transport and laying belts (hereinafter Flortransportb stands) having an obliquely downwardly inclined inlet section with two adjacent running belt sections of Flortransportb stands.
  • the band sections which are brought together at the entrance to the strip inlet, form a narrow inlet slot adapted to the board thickness and run in the inlet section substantially parallel or at an acute angle to each other and close to each other in such a way that they guide or cover the pile on both sides in the inlet section.
  • both pile conveyor belts are passed through the superstructure and through the laying carriage.
  • the previously known constructions have a relatively complicated course of their pile conveyor belts, in particular on the superstructure, where the one of the web conveyor supporting pile conveyor belts wraps around a deflection roller delimiting the inlet section at its lower end by more than 90 °.
  • the arrangement is further complicated by the fact that the second pile conveyor belt is also passed through the superstructure, according to the construction EP 0 865 521 B1 even such that it is the first pile conveyor belt Accompanied in the area of an obliquely downward inlet runway in close proximity.
  • This separate Flor Insertband, better said first masking tape is an endless belt and is stretched by a movable carriage with the laying carriage. Another endless masking tape also runs through the laying carriage, where it is reversed by 180 °, a mirror image of the aforementioned first masking tape and only serves to cover the laid fleece on the other side of the laying carriage. It passes through the same tensioning carriage as the first conveyor belt.
  • the invention has for its object to provide a device of the type mentioned above, which has a simpler, yet reliable guidance of the belts involved in card web transport and pile storage. This object is achieved by a nonwoven, the features of which are specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.
  • the solution of the problem underlying the invention is characterized u.a. characterized in that only one of the flor facilityden belts, namely the Florbahn leading from the entrance of the nonwoven laying Flortransportband is guided through both main cars of the web laying, namely by the superstructure and the laying carriage.
  • this pile transport belt does not leave the laying carriage through the Ablegespalt, but branches off from the card web before it enters the Ablegespalt, and is led out laterally from the laying carriage above the Ablegespalts.
  • the two loops horizontally lying Umlenkwalzenan angelen wrap around each 180 ° and are guided to a common tensioning carriage, which is movable together with the laying carriage and where they turn around two opposing tension rollers wrap around each 180 °.
  • the first of these masking tapes accompanies the pile transport belt between the superstructure and the laying carriage with an upper strand and covers the laid fleece on the delivery conveyor belt with a lower strand.
  • the second cover strip together with this in the carriage a vertically extending baffle surface is formed, which is spanned there by the second cover, in the laying carriage is guided over two vertically spaced guide rollers.
  • the transport direction of the card web entering the laying carriage aims at this baffle surface. For this reason, it is no longer possible to pass the pile conveyor belt on the laying carriage, but it is in the laying carriage and guided directly on this baffle.
  • the pile conveyor belt is therefore deflected in the laying carriage shortly before the baffle surface of a guide roller upwards and then passed back by means of a further deflection roller on the upper run of the second masking tape and later to the input area of the batt.
  • the pile conveyor belt is thus guided in the laying carriage via two deflecting rollers mounted at different heights, which are looped around by the pile conveyor belt by about 90 ° or slightly less in each case. Since the pile conveyor belt leaves the laying carriage at an altitude higher than the upper run of the second masking tape, these tapes can not touch each other and thus frictional effects between them can not occur. This is also an essential aspect of the invention.
  • the pile conveyor belt may be a screen belt, since the pile conveyor belt only takes over transport function, but is not at the same time masking tape.
  • the discharge of air from the pile when pressing the pile on the upper run of the first cover band is favored.
  • the masking tape can therefore be ideally smooth.
  • it can also be provided with a surface structure which produces quasi a form fit between the card web and the band, which avoids the slippage and the undefined sliding of the card web with relative movements between the belt and card web like a screen belt, but is less expensive than a screen belt.
  • the common for the two masking straps tensioner is preferably arranged to save space below the delivery conveyor belt and therefore runs in opposite direction to the movement of the laying carriage.
  • the masking tapes are preferably smooth so as not to disturb the laid web when touched.
  • Fig. 1 shows a schematic view of an embodiment of the invention in a frontally with respect to the delivery conveyor belt view.
  • On the delivery conveyor belt 1 is just a laid start section of a card web 2.
  • About the delivery conveyor belt 1 is a laying carriage 3 on rails (not shown) moved back and forth.
  • In the laying carriage 3 are in accordance with the Fig. 1 and 2 five guide rollers freely rotatably mounted.
  • a first deflection roller 4 is partially wrapped by a first cover strip 5, which has a lower strand 5u, according to Fig.
  • the driven guide roller 7 is coupled to a motor (not shown) and is intended to cover the first cover 5 in to power different directions.
  • a second and a third guide roller 12a and 12b which are rotatably mounted in the clamping carriage 3, partially wrapped by a second cover 13, which is guided via a driven guide roller 14 and a stationary guide roller 15 to a mounted in the first tensioning carriage 9 guide roller 16 is, which is partially wrapped by the second cover strip 13, from where the second cover strip 13 via further stationary guide rollers 17 and 18 to the laying carriage 3 runs back.
  • the second and third guide rollers 12a and 12b are arranged one above the other at such a distance that the portion of the second cover strip 13 extending between them forms a baffle surface 13p, on which the between the upper run 50 of the first cover strip 5 and the adjacent belt conveyor belt 26 formed gap, in which the card web 2 is sandwiched.
  • the second cover strip 13 has a lower run 13u, which runs at a close distance above the delivery conveyor belt 1.
  • the driven deflection roller 14 is coupled to a motor (not shown) and is intended to drive the second cover band 13 in different directions.
  • Fig. 1 a relatively large distance between the lower strands 5u and 13u and the delivery conveyor belt 1 is shown. This should only slightly simplify the overview.
  • this touching can also be a slight pressure, wherein the contact pressure is preferably adjusted by adjusting the height of the delivery conveyor belt. Therefore, the masking tapes 5 and 13 are preferably smooth on their side facing the laid web.
  • a chain or a toothed belt 19 is mounted, which via a with a motor (not shown) connected to the drive gear 20 and a plurality of guide wheels 21 runs.
  • the laying carriage 3 can be moved back and forth across the delivery conveyor belt 1 transversely to its transport direction.
  • an upper carriage 22 is mounted transversely to the transport direction of the delivery conveyor belt 1 on rails (not shown) movable.
  • the uppercarriage 22 has an upper guide roller 23 and a lower guide roller 24, which are laterally offset from each other.
  • About these two rollers 23 and 24 runs over a fixedly mounted in the machine frame deflecting or support roller 25 supported pile conveyor belt 26, which (not shown) by a pile generator (not shown) zoom in from the entrance of the web laying.
  • the web conveyor belt 26 is inclined obliquely downwards.
  • the pile conveyor belt 26 extends parallel to the upper run 50 of the first cover strip 5 into the laying carriage 3.
  • a fourth guide roller 27 is mounted, which deflects the pile conveyor belt by 90 ° or slightly less upwards and thus lifts off the card web.
  • a fifth guide roller 28 is mounted, which is looped by the pile conveyor belt in the same arc as the fourth guide roller, but in the opposite direction.
  • the pile conveyor belt 26 leaves the laying carriage 3 above the upper run 130 of the second cover strip and at a distance to this, wraps around a stationary mounted in the machine frame drive roller and runs from there via a tensioning roller mounted in a second tensioning carriage 30 31, then stationary over several in the machine frame stored deflecting rollers to get to the input of the webbed.
  • the uppercarriage 22 and the second tensioning carriage 30 are connected to each other via a chain or a toothed belt 32, which runs via a drive gear 33 connected to a motor (not shown) and a deflection wheel 34 which are mounted in the machine frame. Furthermore one recognizes in Fig. 1 an obliquely upwardly extending feed belt 35, which feeds the pile web 2 to be laid to the pile conveyor belt 26.
  • the pile conveyor belt 26 and the upper run 50 of the first cover strip 5 are guided parallel to each other in close proximity, so that a guided from the Flortransportband 26 card web 2 in the mentioned area between the superstructure 22 and the laying carriage 3 from the pile conveyor belt 26 and the upper run 50 of the first cover strip 5 is sandwiched.
  • the card web 2 is supported by said masking tape 5, which nevertheless does not need to take over any drive function on the card web supported by it in this area since the web transport belt 26 is intended and capable of doing so.
  • a suction device 36 is advantageously provided in the superstructure 22, as schematically indicated in the drawing, which faces the pile conveyor belt 26 in the region of the inlet line on the side facing away from the pile support surface.
  • a vacuum built up by the suction device 36 helps to keep the card web 2 on the first pile conveyor belt 26.
  • the use of a wire belt as a pile conveyor belt 26 is particularly advantageous because it is possible with his help, in the area between the superstructure 22 and the laying carriage 3, where two bands are guided in parallel and sandwich the sandwich web 2 between them, the air from the To press out felt 2 without fibers fading sideways and the fiber orientation is disturbed by the outflowing air.
  • the first tensioning carriage 9 performs an opposite movement, because the loop lengths of the cover strips 5 and 13 are constant. Furthermore, the uppercarriage 22 and its associated second tensioning carriage 30 perform in operation a mutually opposite movement, because they are non-positively connected by the chain or the timing belt 32.
  • the second tensioning carriage 30 is necessary to keep the loop length of the pile conveyor belt 26 constant.
  • the kinematics of superstructure 22 and laying carriage 3 are completely identical to those in EP 0 865 521 B1 is described.
  • the movements of laying carriage 3 and upper carriage 22 are coordinated so that when feeding the card web 2 on the feed belt 35 with uniform speed controlled storage of the card web 2 without stretching or compressions can take place within the illustrated web laying on the delivery conveyor belt 1. This also takes into account the fact that the laying carriage 3 in the region of its reversal position must be braked to a standstill and accelerated again.
  • the movement can be controlled by independent control
  • Upper carriage 22 and carriage 3 are made in a known manner Florbahnpuff réelle within the batt.
  • the buffering required to compensate for the wobbling carriage speed is superimposed on a second buffering required to compensate for the fluctuating pile infeed speed.
  • these bufferings can possibly be in phase opposition to one another, ie cancel each other completely or partially
  • the drives of the masking tapes are controlled by means of the drive rollers 6 and 14 so that the cover strip lying in the direction of movement of the laying carriage 3 simply puts on the laid fleece and this does not move, while in the direction of movement of the laying carriage 3 front cover strip moves with respect to the speed of movement of the laying carriage 3 double speed forward.
  • the masking tapes 5 and 13 form at the point where they are deflected in the laying carriage 3 by their guide rollers 4 and 12, a gap, which is initially referred to as Ablegespalt.
  • the first cover strip 5 is driven so that its upper run 50 follows the movement of the pile transport belt 26, because both belts enclose the card web 2 on its way between the upper carriage 22 and the laying carriage 3 between them.
  • the first cover strip 5 is preferably driven so that the peripheral speed of the first guide roller 4 in the laying carriage 3 is exactly as large as the Peripheral speed of the second guide roller 12a, but has the opposite direction of rotation.
  • Fig. 2 shows as a detail "X" Fig. 2
  • the pile conveyor belt 26 and the first cover strip 5 are guided parallel to each other, so that they include the card web 2 between them.
  • the first cover strip 5 wraps around the first guide roller 4 in the laying carriage by 180 ° and thereby takes the web of sheets to be deposited into the discharge gap between the first guide roller 4 and the second guide roller 12a.
  • the second cover strip 13 wraps around the second guide roller 12a and the third guide roller 12b mounted above the same in the carriage 3 by 180 ° together.
  • the web conveyor belt 26 is lifted off the card web 2 by the fourth deflecting roller 4 mounted above the first deflecting roller 4 and deflected out of its path directed towards the baffle 13p and then passes over the fifth guide roller 28 which is mounted above the third deflecting roller 12b in the laying carriage and wins thereby distance from the upper run 13o of the second cover strip.
  • the third guide roller 27 is advantageously adjustable within the laying carriage 3 in height, which is symbolized by the double arrow Y to the distance between the first and second guide rollers 4 and 27 and thus the distance between the bands passing over them 5 and 26 to the To be able to adapt the thickness of the processed card web.
  • the upper carriage 22 and the laying carriage 3 are also mounted in their height positions adjustable against each other in order to adjust the mutual distance between the upper carriage 22 and the carriage 3 parallel guided bands 22 and 5 can.
  • the lower guide roller 24 may be mounted vertically adjustable within the upper carriage 22, which also by a double arrow Y in Fig. 1 is symbolized.
  • the distance between the first guide roller 4 on the one hand and the second and third guide rollers 12a and 12b on the other hand adjustable to change the width of the Ablegespalts, which is symbolized by the double arrow Z, possibly with appropriate adjustment of the guide roller 16 in the first Tensioning carriage 9 in the direction of arrow Z.
  • the invention thus enables a very simple management of all participating in the treatment process belts and has the additional advantage that the card web is deflected only twice within the batt, namely on the superstructure by a total of 180 ° and the laying carriage by 90 ° before moving to the delivery conveyor belt arrives.
  • the Flortransportband can be optimized for its intended purpose, because it does not need to cover function on the laid fleece, and the masking tapes can be made smooth because they do not participate in the pile drive, an optimal treatment of the card web is guaranteed in the nonwoven.
