Definitions

  • the invention relates to a nonwoven with a superstructure and a laying carriage, which are guided in a machine frame above a circulating Abendertransportbandes transversely to the transport direction, and with conveyor belts, which sandwiches a to be deposited web on its way from a pile entrance to a Ablegespalt include between them, for depositing the nonwoven fabric fed card web in partially overlapping layers on the delivery conveyor belt.
  • EP 0 865 521 B1 is known a nonwoven layering apparatus of the aforementioned type, in which a first pile conveyor belt feeding the web is guided both through the uppercarriage and through the laying carriage and continues to run through an auxiliary carriage located below the delivery conveyor belt, which supports a tensioning roller and serves to to keep this pile conveyor taut.
  • a second pile conveyor belt is also passed through the superstructure and the laying carriage and passes through a second, below the Abrotetransportbandes in the machine frame transversely movable auxiliary carriage, which supports a further tension roller and serves to keep the second Flortransportband taut.
  • the Flor supplying first Flortransportband runs in the superstructure on two arranged at different heights of rollers, which are offset transversely to their axial direction against each other, so that there is an obliquely downward inclined Floreinlauf.
  • This oblique Floreinlauf is accompanied in the superstructure of the second Flortransportband, which runs laterally in the area between the superstructure and the laying carriage parallel to the first-mentioned Flortransportband and encloses together with this to be deposited pile on both sides.
  • the two pile conveyor belts on the lower guide roller in the upper carriage can not be performed parallel to each other, because there are different radii of rotation and thus caused friction effects that could affect the guided pile, the second pile conveyor belt on the upper carriage in the region of said lower guide roller over a total of four separate deflection rollers guided before it approaches the first Flortransportband again.
  • Corresponding measures are also taken for the first pile conveyor belt on laying carriage, since this band can not be performed together with the second pile conveyor belt in the laying gap on laying carriage for the same reasons explained.
  • the strands of the two pile conveyor belts leaving the laying carriage at the discharge gap extend close to the delivery conveyor belt and assume the function of covering the laid nonwoven there in order to protect it against aerodynamic impairments resulting from the movement of the laying carriage.
  • the invention has for its object to provide a nonwoven, the type mentioned above, which has a simplified course of the belts involved in the pile transport and on the pile guide, while allowing a high operating speed.
  • the invention provides a novel combination of a feeder and one of the known sandwichers. It takes over from the sandwich-makers, the movable pile inlet, which is laid in the superstructure, used as a laying carriage such as is known by the Wagenlegern, in which a car circulates an endless conveyor belt, moves superstructure, laying carriage and despatch conveyor but so close together that the card web is sandwiched between conveyor belts on their way from the pile inlet to Ablegespalt and the laid web on the delivery conveyor belt touched by the lower strand of the conveyor belts, so is covered.
  • the pile guide in laying carriage serves an endless pile conveyor belt, which rotates exclusively in the laying carriage and is thus moved back and forth together with this transverse to the delivery conveyor belt.
  • This endless belt which revolves only in the laying carriage, on the one hand participates in the transport of the card web in the direction of the depositing gap and on the other hand covers the nonwoven fabric produced on the delivery conveyor belt and produced from the laid card webs.
  • the laying carriage conveyor belt wraps except one of the Ablegespalt limiting rollers, hereinafter called Ablegewalzen, also mounted in the laying carriage at a distance from the laying rollers deflection roller, which, if it is mounted vertically adjustable in the laying carriage, opens up the possibility of the direction of movement of the laying carriage in a special way Take into account. If you make the diameter of this guide roller smaller than that of the associated first depositing roller, can be achieved by height adjustment of the guide roller and further, to be discussed in more detail later features that in both directions of movement of the laying carriage on the laid fleece optimum coverage conditions by said Legewagen- Result conveyor belt.
  • the nonwoven layer according to the invention is equipped with an oblique pile inlet, comparable to the prior art according to the aforementioned EP 0 865 521 B1 Located on the movable superstructure.
  • the card fed on the upper carriage reaches the upper run of the carriage carriage, from which it is transported in the laying gap on the laying carriage. It is accompanied and covered by the leading the Flor web Floreinlauf conveyor belt, which runs on the laying carriage via a guide roller and from there via the second depositing roller through the laying gap, from where this tape extends transversely across the delivery conveyor belt and takes over covering function there.
  • Said guide roller is the only roller which serves to prevent the described frictional effects, which result when two bands enclosing the web between them run around one and the same guide roller and therefore describe webs which have different radii. Leaving the laying gap, the pile infeed conveyor belt runs over the laid fleece and, via a tensioning roller mounted in a movable tensioning carriage, back to the inclined pile infeed.
  • the invention is characterized in that there are extremely few deflection points for the card web and the bands involved in their leadership. However, it requires a little more space at the side of the delivery conveyor belt for the movement of the in his direction of movement on the delivery conveyor belt laterally sweeping laying carriage.
  • the nonwoven layer according to the invention is therefore of particular interest for small laying widths.
  • the invention also has the advantage that a real sandwich guidance of the deposited web for all possible pile thicknesses can be realized, because the inventive design of the web laying allows the florestden tapes in the area between upper and laying carriage in a very simple manner in height against each other adjust.
  • the spacing of the bands can be made zero in this range. For this purpose, it is sufficient if the trajectory of the laying carriage is made adjustable in height.
  • the desired contact between the lower strands of the Flor depositing bands and the laid fleece can be made by adjusting the height of the delivery conveyor belt in the base frame and reach to light pressing.
  • the single drawing shows a schematic view of an embodiment according to the invention.
  • a nonwoven is shown schematically, consisting of a stored in a base 1 Ab radiatortransportband 2, which is for example a slat belt and of which a deflection roller is shown, a in a machine frame 3 (shown schematically) transversely to the transport direction of the delivery conveyor belt 2 movable upper carriage 4 and one below the same transversely to the delivery conveyor belt 2 movable carriage 5.
  • a florunitdes conveyor belt which is hereinafter referred to the distinction Floreinlauf conveyor belt 6 and which runs over several mounted in the machine frame 3 guide rollers, some of which are stationary guide rollers and another one on a horizontal in the machine frame 3 back and forth movable carriage or clamping carriage 18 mounted tension roller 7 is.
  • the stationary rollers at least one roller 24 is driven, which is symbolized in the drawing by two blackened sectors.
  • the superstructure 4 has two guide rollers 8 and 9, which are arranged at different heights and laterally offset from each other, so that in a known manner results in an obliquely downward Floreinlauf.
  • the pile infeed conveyor belt 6 is deflected by more than 90 °.
  • He stands there preferably a stationary in the uppercar 4, but yieldingly movable pile guide device 10, which serves to improve the leadership of a guided from the pile infeed conveyor belt 6 card web 11 and preferably is permeable to air to derive entraining air from the card web 11 as possible unhindered.
  • two guide rollers 12 and 13 are mounted parallel to each other at a close distance, which are referred to below as the first and second depositing rollers for distinguishing other guide rollers, as already mentioned above.
  • the first depositing roller 12 runs an endless Flor Entryband 14, which rotates only within the laying carriage 5 and is subsequently called Legewagen conveyor belt.
  • This band 14 has an upper run 14o and a lower run 14u. It runs over a deflecting roller 15 arranged at a distance from the first depositing roller 12 and wraps around it.
  • a belt spreading device 16 is arranged in the laying carriage 5, which in the illustrated example is formed by two freely running belt guide rollers of relatively small diameter, ie a diameter which is smaller than that of the first depositing roller 12.
  • This belt spreader 16 serves to keep the upper and lower strands 14o and 14u of the carriage transporting belt 14 parallel to each other in the portion between the belt spreader 16 and the first depositing roller 12.
  • the guide roller 15 also has a comparatively small diameter and is mounted vertically adjustable in the laying carriage 5, which is symbolized by the arrow Y.
  • the laying roller 12 wrapping around the laying carriage conveyor belt 14 forms between the lower belt guide roller of the belt spreader 16 and the first depositing roller 12 distant guide roller 15 from a band portion which is inclined in the direction of movement of the laying carriage 5 to the right obliquely upward, since in this situation the Deflection roller 15 is brought into the raised position shown in the drawing.
  • the guide roller 15 is lowered to the height of the lower belt guide roller of the belt spreading device 16 (not shown).
  • the upper run 14o of the laying carriage conveyor belt 14 is supported in its horizontally extending portion between the first depositing roller 12 and the belt spreading 16 from below, for example by a smooth plate 19th
  • adjusting devices may be present on the guide roller 15 or on this holding movable frame mounted driver (not shown) act selectively, so that the current altitude of the guide roller 15 is made the current position and direction of movement of the laying carriage results.
  • the actuators may e.g. be pneumatic type.
  • the guide roller 15 may be mounted on pivot arms which are mounted in the space enclosed by the band 14 and under the influence of anchored in the laying carriage 5 tension springs or even under the outgoing from the belt 14 tensile stresses, the guide roller in its upper and lower end positions, which are stable in this way, while the intermediate positions are unstable, so that a change in the altitude of the actuators is only triggered, the rest of the movement but done automatically.
  • a guide roller 17 is parallel to the two depositing rollers 12 and 13 stored.
  • the pile infeed conveyor belt 6 runs starting from the lower guide roller 9 on the upper carriage 4, until it reaches the second depositing roller 13 and wraps around it.
  • the pile infeed conveyor belt 6 extends at the same height as the lower run 14u of the laying carriage conveyor belt 14 to the driven deflection roller 24. It is able to cover the nonwoven lying on the delivery conveyor belt 2 and extends beyond the deflection roller 24 2 inter alia on the already mentioned tension roller 7 back to the oblique pile inlet.
  • the path of a card web fed to the card web 11 on the delivery conveyor belt is as follows:
  • the zoomed-in from the infeed conveyor belt 6 card web 11 runs over the superstructure 4 obliquely downwards in the area between the deflection rollers 8 and 9 mounted there and then passes to the upper run 14o of the laying carriage conveyor 14. From there it is at its top by the Untertrum the pile infeed conveyor belt 6 covered that the lower guide roller 9 partially wraps around and runs in the direction of the laying carriage 5.
  • the card web 11 then passes into the Ablegespalt between the Ablegewalzen 12 and 13, which are partially wrapped by the two bands 14 and 6. From the Ablegespalt enters the card web 11 on the delivery conveyor belt 2.
  • a plurality of superimposed pile web layers are represented by a kind of package.
  • a first toothed belt 20 is present, which runs over a bearing in the machine frame 3 drive pinion 21.
  • the first toothed belt 20 is coupled to the superstructure 4 and the tensioning carriage 18 and thus moves them necessarily synchronously and opposite to each other.
  • a second toothed belt 22 is provided, which is coupled to the laying carriage 5 and runs over two mounted in the machine frame pinion 23, one of which is driven.
  • the depositing rollers 12 and 13 are interlocked with each other so that they forcibly rotate counter to each other.
  • the pile infeed conveyor belt 6 is driven by the deflection roller 24.
  • the lower run of the pile infeed conveyor belt 6 at a close distance over the laid fleece with a relation to the speed of the laying carriage 5 double speed. So that no disturbing effects on the laid fleece are caused, this pile infeed conveyor belt 6 should be as smooth as possible on its side facing the fleece.
  • the card web 11 experiences only two critical deflections within the batt, namely at the lower guide roller 9 of the upper carriage 4, where it is deflected by about 135 °, and at the inlet into the laying gap, where they are 90 ° is diverted. Particularly simple is the course of flourishing bands.
  • the leading the card web 11 Floreinlauf conveyor belt 6 passes only through the superstructure 4 and the laying carriage 5 and passes through the tensioning roller 7 overlapping tensioning carriage 18 and some fixed guide rollers, as usual. But it lacks a second comparable Flortransportband that is passed through both cars.
  • the invention is content with a kind of auxiliary belt, which rotates in the form of the laying carriage conveyor belt 14 exclusively in the laying carriage 5 and is transported back and forth with this. Separate masking tapes can be dispensed with, since their function is taken over by the lower strands of the two aforementioned bands 6 and 14.
  • the guide roller 17 can be adjusted in the carriage 5 in height, ie For example, it would be raised accordingly when lowering the laying carriage 5.
  • the altitude of the delivery conveyor belt 2 is adjustable. Instead of a change in the altitude of the laying carriage 5 and a change in the altitude of the superstructure 4 can be considered.
