Definitions

  • the present invention relates to a nonwoven layer for laying a nonwoven fabric from a card web.
  • Nonwovens serve to deposit the card web produced by a carding machine as evenly as possible on a delivery conveyor belt in multilayered layers to form a nonwoven.
  • the card web is usually first passed through a superstructure and from there to a laying carriage, through the Ablegespalt the card web is placed on the delivery conveyor belt.
  • At least two pile conveyor belts serve to guide the card web through the nonwoven layer. The movements of the pile conveyor belts, the superstructure and the laying carriage are controlled in a coordinated manner.
  • EP 1 816 243 A1 describes a generic fleece layer.
  • Fleece layerers are often preceded by means for changing the pile speed, which are used primarily to control the pile density of the pile sheet in order to be able to produce a profiling of the laid nonwoven fabric or to perform an edge thickness compensation of the laid nonwoven web.
  • Such means for changing the Florlauf für include, for example, different speed driven driven rollers on the carding machine upstream carding, as for example WO 99/24650 A1 is known, or the provision of a separate drafting between carding and nonwoven, see for example EP 1 532 302 B1 ,
  • WO 2010/073221 A2 describes a pile store, in which the pile is sandwiched between two moving pile conveyor belts.
  • a vertically adjustable pressure roller presses the overhead pile conveyor belt on the underlying pile conveyor belt and is thus responsible for the size adjustment of the storage tank.
  • the present invention has for its object to provide a nonwoven fabric, which has an integrated pile memory, which provides in a simple manner compensation fluctuating Floreinlauf füren already before the entry of the card web in the superstructure of the web laying.
  • the nonwoven laying for laying a fleece from a card web on a transversely movable superstructure through which the card web is guided, also a transversely movable carriage, through which the coming from the superstructure card is guided and the delivery of the card web on a delivery conveyor belt serves.
  • the nonwoven depositor has at least two pile conveyor belts for guiding the pile web to the uppercarriage and further to the laying carriage, wherein the upper run of a first rotating rough pile conveyor belt extends from an inlet region of the web laying machine to the uppercarriage.
  • a positionally variable pressure means is provided, which is operable to produce a variable pile storage in the upper run of the first Flortransportbandes.
  • an integrated buffer is provided in a nonwoven, which does not require additional control of the superstructure and easily compensates for fluctuating Floreinlauf füren during operation of the web laying on the card web before the card web enters the superstructure.
  • the pressing means is a pressure roller, which is preferably vertically adjustable.
  • the formation and control of a variable memory storage can be done only by movement of a single element.
  • a smooth cover tape is arranged between the upper run of the first pile conveyor belt and the pressure roller, while the first pile conveyor belt is rough. In this way, it is ensured that the card web is merely advanced due to friction through the first pile conveyor belt while sliding along the smooth cover tape. At the same time a decoupling of the pressure roller is achieved by the card web through the intermediate masking tape.
  • the pressing means is a sword.
  • the sword has a smooth surface while the first pile conveyor belt is rough.
  • the card web can in turn be moved forward due to friction of the first Flortransportband and slide along the sword in this area.
  • the pressure roller is preferably movable so that it presses from above on the cover and thus also the upper run of the first pile conveyor belt. It is advantageous if the pressure roller presses on an oblique inlet portion of the cover strip and the first Flortransportbandes. Such a solution for the formation of the storage memory is mechanically preferred.
  • two deflecting rollers of the first pile conveyor belt form lateral boundaries of the pile store and thereby serve as clamping aids in the formation of the pile store initiated by the pressure roll. This allows a defined change in the size of the memory without the use of additional resources.
  • the sword is obliquely displaceable and is surrounded at least in a partial section of the first pile conveyor belt in forming the variable pile memory.
  • the first pile conveyor belt preferably runs along a first side surface of the sword, then over the blunt, relatively broad tip of the sword and then along the second side surface of the sword. In this way, can be extended or shortened around the sword only by shifting the sword of the existing from the beginning loop-shaped course of the card.
  • two deflection rollers of the first pile conveyor belt form lateral boundaries of the pile store and serve as clamping aids in the formation of the pile store initiated by the sword.
  • a moveable tensioning carriage is preferably provided, through which the first pile conveyor belt runs.
  • This tensioning carriage can be controlled or regulated according to the required additional length of the first pile conveyor belt and thus provide a balance, so that the first pile conveyor belt remains unaffected in terms of its overall length.
  • Fig. 1 shows a schematic cross-sectional view of a nonwoven layer 2, to which the present invention can be applied.
  • the nonwoven layer 2 with an endless circulating delivery conveyor belt 4, which is intended, one from a card web 6 (see Fig. 2 ) Fleece laid in a direction perpendicular to the drawing plane transport direction. From guide devices of the delivery conveyor belt 4, an upper guide roller 8 is shown.
  • the card web 6 is for clarity only in Fig. 2 shown.
  • the delivery conveyor belt 4 is a laying carriage 10 on rails or tubes (not shown) moved back and forth.
  • two guide rollers 12 and 14 are freely rotatably mounted.
  • the first guide roller 12 is partially wrapped by a pile conveyor belt 16, hereinafter also called second pile conveyor belt 16.
  • the second pile conveyor belt 16 is fixedly secured at its first end 18 in the machine frame, not shown, of the webbing 2 and runs from there at a close distance above the delivery conveyor belt 4 to laying carriage 10, where it is deflected by 180 ° and then four stationary guide rollers 20, 22, 24, 26 is returned to the second guide roller 14 in the laying carriage.
  • the deflecting roller 14, which is also rotatably mounted in the laying carriage 10, is partially wrapped by the second web conveyor belt 16, so that the web conveyor belt 16 is deflected by 180 ° and from the lower exit region of the laying carriage 10 in dense distance above the delivery conveyor belt 4 runs until it is in turn connected at its second end 28 fixedly connected to the machine frame of the web layer 2.
  • a chain or a toothed belt is mounted, which runs for example via a drive gear connected to a motor and a deflection wheel (all elements not shown). With the aid of these drive devices, the laying carriage 10 can be moved back and forth across the delivery conveyor belt 4 transversely to its transport direction.
  • an upper carriage 30 transversely to the transport direction of the delivery conveyor belt 4 on rails or tubes (not shown) movably mounted.
  • the rails or tubes may be the same rails or tubes on which the laying carriage 10 is movably mounted.
  • the uppercarriage 30 has an upper deflecting roller 32 and a lower deflecting roller 34, which are laterally offset from one another.
  • About these two guide rollers 32, 34 runs another Flortransportband 36, which is subsequently called first Flortransportband 36.
  • the first pile conveyor belt 36 slopes inclined downwards.
  • the first Flortransportband 36 runs parallel to the right upper strand of the second Flortransportbandes 16.
  • the first Flortransportband 36 runs straight through the laying carriage 10 and is after the laying carriage 10 via a stationary mounted, motor-driven guide rollers 38 and from there via a guide roller 42 mounted in a tensioning carriage 40, in order to then run over a plurality of guide rollers 44, 46, 48, 50 fixedly mounted in the machine frame of the webbing 2 before it reaches the superstructure 30 again.
  • the superstructure 30 and the tensioning carriage 40 may be connected to each other via a chain or a toothed belt (not shown) which runs via a drive gearwheel (not shown) and a deflection wheel, which are mounted in the machine frame (not shown).
  • the clamping carriage 40 is also on rails or tubes (not shown) movably mounted. It may also be advantageous if the movements of superstructure 30 and clamping carriage 40 are decoupled from each other.
  • Fig. 1 One recognizes in Fig. 1 in that, during operation, the superstructure 30 and its associated tensioning carriage 40 execute a mutually opposite movement.
  • the tensioning carriage 40 serves to keep the loop length of the first pile conveyor belt 36 constant.
  • the movements of laying carriage 10 and superstructure 30 are coordinated so that when feeding the card web 6 at a uniform speed in the nonwoven 2 a controlled storage of the card web 6 without stretching or compression within the batt 2 on the delivery conveyor belt 4 can take place.
  • the superstructure 30 moves in each case in the same direction, on average only half as fast as the laying carriage 10. It is also taken into account that the laying carriage 10 has to be decelerated in the region of its movement reversal position to a standstill and accelerated again.
  • a gap is formed, which is referred to as a discharge gap.
  • both pile conveyor belts 16, 36 are driven so that they run at the same speed.
  • the card web 6 is supplied at a variable speed, for example because a cyclically operating drafting arrangement (not shown) is arranged in front of the nonwoven layer 2 which produces an alternating thickness in the card web 6 for the purpose of achieving a transverse profiling of the laid nonwoven fabric Buffer memory in the nonwoven layer 2 a Florbahnpuff ceremonies be made within the batt 2.
  • a cyclically operating drafting arrangement (not shown) is arranged in front of the nonwoven layer 2 which produces an alternating thickness in the card web 6 for the purpose of achieving a transverse profiling of the laid nonwoven fabric Buffer memory in the nonwoven layer 2 a Florbahnpuff ceremonies be made within the batt 2.
  • this variable pile memory is formed in the inlet region of the web layer 2 without requiring change in the control of the uppercarriage 30 and the laying carriage 10.
  • the fleece layer 2 for this purpose has a cover strip 52 which extends from an inlet region of the fleece layer 2 up to at least the superstructure 30.
  • the cover strip 52 in this case runs directly above an upper run 54 of the first pile transport belt 36, which serves as a support surface for the card web 6 in this area and is moved in the direction of the arrow A.
  • the card web 6 is thus enclosed between the upper run 54 of the first pile transport belt 36 and the cover 52.
  • the first Flortransportband 36 is formed rough, preferably as an air-permeable screen belt
  • the cover 52 is formed smooth and arranged substantially stationary in the nonwoven layer 2.
  • the cover strip 52 is preferably impermeable to air and formed, for example, from Teflon or PVC coated fabric.
  • first pile transport belt 36 is impermeable to air, e.g. has a cubed PVC surface while the stationary cover tape 52 has pores to allow air leakage without becoming rough. It is also conceivable for some applications that both the cover band 52 and the first pile transport belt 36 are impermeable to air.
  • the circulating first Flortransportband 36 moves due to frictional forces on the lying thereon card web 6, and the cover 52, which is not moved with the card web 6, serves as a stationary cover, thus preventing unwanted turbulence or blowing of fibers of the card web 6.
  • the card web 6 remains largely free of turbulence, which higher Florlauf Oberen can be realized.
  • the card web 6 is guided as a sandwich between the upper strand 54 of the first pile transport belt 36 and the cover 52, wherein it is moved only by the movement of the first Flortransportbandes 36 forward and the smooth cover belt 52 is not a hindrance to the movement of the card web 6 ,
  • the masking tape 52 does not necessarily cover the entire upper run 54 of the first pile transport belt 36, but preferably extends from the entrance area of the batt 2 through the uppercarriage 30.
  • the substantially stationary cover band 52 is preferably fixed at its two ends to the machine frame of the fleece layer 2.
  • the cover strip 52 then extends from a first attachment point 56 in the inlet region of the webbing 2 of the web of the first Flortransportbandes 36 to the superstructure 30, through the latter and from the superstructure 30 horizontally to the second attachment point 58 at the rear end of the web layer 2.
  • the cover band 52 is preferably mounted by means of stretchable means 60 in the machine frame of the web layer 2.
  • the expandable means 60 may comprise either springs or pneumatic cylinders or other suitable elements.
  • the fleece layer 2 also has a pressing means in its inlet area, in this case a vertically adjustable pressure roller 62.
  • the pressure roller 62 is positionally variable and preferably movable such that it presses from above onto the cover strip 52 and thus simultaneously onto the upper run 54 of the first pile transport belt 36. This movement can be assisted by a support roller 64, which is likewise arranged in the inlet region of the fleece layer 2 and presses on the cover strip 52 from above.
  • a support roller 64 which is likewise arranged in the inlet region of the fleece layer 2 and presses on the cover strip 52 from above.
  • the guide roller 48 in cooperation with the guide roller 46.
  • the extended path of the card web 6 then runs between the extended pressure roller 62 and the guide roller 48 substantially perpendicular, as shown in dashed lines of memory formation in Fig. 2 evident.
  • the pressure roller 62 presses on an oblique inlet section 66 of the cover strip 52 and thus also of the first pile transport belt 36.
  • the expandable means 60 are provided, by means of which the suspension of the cover strip 52 can be extended at its two ends.
  • the situation is different for the moving first pile conveyor belt 36.
  • the tensioning carriage 40 can be actuated correspondingly changed.
  • the tensioning carriage 40 can deliver additional length of the first pile conveyor belt 36 required by movement to the left in the pile store and at the same time leave the total length of the first pile conveyor belt 36 unchanged.
  • Fig. 3 is shown a possibility of guiding the cover strip 52 in the uppercar 30. Due to the back and forth of the upper carriage 30, the substantially stationary cover band 52 must experience a support both to the left and to the right, so that it can slide through the latter during the movement of the upper carriage 30 in a defined manner. For this purpose, one needs an additional guide element 68, in the illustrated example, a guide shoe, which must be as smooth as possible and the lower guide roller 34 of the upper carriage 30 is adjacent.
  • Fig. 4 an alternative possibility of guiding the cover band 52 in the uppercarriage 30 is shown.
  • the guide element 68 is designed as a co-moving with the superstructure 30 smooth roller, which is arranged above the lower guide roller 34 and the cover strip 52 is deflected.
  • an additional guide means 69 is provided for the guidance of the card web around the lower deflection roller 34, for example that EP 1 947 223 A1 known guiding means.
  • a total of two pile conveyor belts 16, 36 are contained in the fleece layer 2.
  • the invention can also be applied to other fleece layers with two pile conveyor belts, as well as to all other fleece layers, including those with three tapes.
  • An example of such a fleece layer with three pile conveyor belts is in Fig. 5 shown.
  • the illustrated nonwoven layer is the second pile conveyor belt 16 of the embodiment Fig. 1 replaced by a second pile conveyor belt 70 and a third pile conveyor belt 72, which are deflected in a common tensioning carriage 74.
  • the invention is also applicable to reverse web layers in which the uppercarriage 30 and the laying carriage 10 move in opposite directions, or to the low-arm leveler.
  • the positionally variable pressing means is designed as a displaceable sword 76.
  • the sword 76 is preferably oriented obliquely and extends between two guide rollers 47 and 48 of the first Flortransportbandes 36.
  • the sword 76 is provided with a smooth surface, so that the forward movement of the card web 6 is done exclusively by the first rough Flortransportband 36, while the card web along the smooth sword 76 slides along.
  • the sword 76 can be moved back and forth. For shifting all common to the expert drive means can be used.
  • the upper run 54 of the first pile conveyor belt 36 thus runs in the formed pile memory along a first side face 78 of the sword, after which it is guided over the tip 80 of the sword 76 and then along the second side face 82 of the sword 76.
  • the dimensions of the sword 76 are selectable depending on the application, but the tip 80 of the sword 76 should be relatively blunt and wide to allow easy sliding of the card web 6 over the tip 80.
  • the tip 80 could be modeled, for example, the shape of a semicircle.
  • the first side surface 78 and the second side surface 82 of the sword 76 are arranged parallel to each other.
  • the side surfaces 78, 82 of the sword 76 may also be curved and / or diverge from the tip 80 of the sword 76.
