Definitions

  • the invention relates to a nonwoven fabric for producing a nonwoven web, with a delivery conveyor belt and a laying member having a portion with a discharge gap, which is guided above the Abendertransportbandes in a machine frame transversely to the transport direction of the delivery conveyor belt, for storing the Fibrous web on the delivery conveyor in partially overlapping layers.
  • Nonwovens of this type are well known and, for example, in “ Nonwovens ", Verlag Wiley-VCH, Weinheim, 2000, page 160 described.
  • the fleece layer shown there is a low-pile fleece layer.
  • a fibrous web hereinafter shortened card web
  • a delivery conveyor belt of the laying arm of the steep-arm webbed When placing a fibrous web, hereinafter shortened card web, on a delivery conveyor belt of the laying arm of the steep-arm webbed performs a pivoting movement, with its lower, free end moves at a close distance above the delivery conveyor belt transversely to the transport direction.
  • the lower end of the laying arm is coupled to a carriage, which is movable on rails transversely to the transport direction of the delivery conveyor belt.
  • the carriage is connected to a drive device, so that with their help by means of the movement of the carriage, the pivoting movement of the laying arm is produced.
  • the speed with which the card web is delivered by the cross-lapper can be more than 200 m / min, speeds in the range of 300 m / min and more are desired. Accordingly, the free end of the laying arm must move over the delivery conveyor belt in order to avoid material compression and wrinkling in the deposited pile. These high speeds bring about problems caused by aerodynamic effects.
  • a card web section deposited by the nonwoven layer can lift off and flutter under its aerodynamic suction effect. It has therefore already been thought to arrange a garnished pressure roller at the free end of the laying arm, which entangles the fibers of the freshly deposited pile layer with the fibers of the underlying, already laid pile layers. Since a laying arm usually gives off in both pivoting directions fibrous web, therefore, two such pressure rollers must be mounted on the laying arm, which increases its weight accordingly. It should also be noted that the effect produced by such pressure rollers can be, is relatively modest.
  • a device for depositing a flexible material web is described with a counter-rotating pair stored in a carriage laying rollers with which the material web is transported and fed to a depository, under the reciprocating motion of the carriage from the supplied material web a stack of euro pallet size and more and up to 1.5 m in height for storage and transport.
  • a guide roller is mounted laterally next to each laying roller over which a cover strip is guided, which is firmly anchored at one end outside the deposit and at the other end in response to the carriage movement on a motor or from a roll up and unwound ,
  • a disadvantage of this construction is that very easily fibers can be trapped in the gusset between the two rollers located in the direction of movement on the carriage during processing of fiber material, since the opposing surfaces of the rollers are moved in the same direction and favor the fiber feed into this gap ,
  • the bands are also used as masking tapes, as is generally known in Flachtäflem who work with superstructure, laying carriage and possibly Spanhwagen.
  • the pile conveyor belts thus form covering strips above the delivery conveyor belt for the delivery conveyor belt deposited pile and thereby reduce the adverse effects caused by the aerodynamic effects.
  • the construction is very complicated, since the two conveyor belts must be guided not only on the actual laying organs, but also around the delivery conveyor belt around.
  • the movement of the bands in the area where they cover the pile on the delivery conveyor belt is tightly coupled to the movement in the feed area, which in some cases prohibits desired separate control of belt speeds.
  • the same problems arise if one were to adapt the ideas of the aforementioned earlier patent application to a flat-roofer.
  • the invention has for its object to provide a nonwoven layering of the type mentioned, which is able to work at high laying speed, while avoiding the adverse effect of aerodynamic effects on the manufactured product, is simple and opens up large adjustment options for the operation.
  • a carriage is arranged, which can be moved in the machine frame transversely to the transport direction of the delivery conveyor belt is guided in the carriage, two upper guide rollers are rotatably mounted, which are each surrounded by a cover strip from which a lower, inner strand runs tightly over the delivery conveyor belt and an upper, outer strand at a distance therefrom, and the guide rollers a have such a distance from each other that the masking tapes together form a gap from the passage of the coming from the discharge gap of the laying member fibrous web on the delivery conveyor belt on the upper guide rollers
  • the Flor feeding conveyor belts and the laid pile, or rather the nonwoven web in the laying area of the same covering tapes are separate components that are basically independent of each other and therefore can be driven independently. Not only does this simplify the construction of the entire web laying machine, it also gives freedom in the control of the movements with which the product quality can be influenced because of the independence of the masking tapes from the napkins.
  • Fig. 1 shows a nonwoven layer 1 according to the invention, in front of the inlet E a pile store 2 is arranged.
  • the fleece layer 1 is a steep-arm leveler which has a feed arm 3 and a laying arm 4, which are hinged together.
  • the feed arm 3 is pivotally mounted about a lower, stationary pivot axis 5.
  • the laying arm 4, which extends downwardly therefrom, is articulated in an upper pivot bearing 6, the lower, free end of which is movable horizontally over a delivery conveyor belt 7 in a linear path extending transversely to the direction of movement of the laying arm 4.
  • Two pile conveyor belts are guided via the feed arm 3 and the laying arm 4, namely a first or upper pile conveyor belt 8 and a second or lower pile conveyor belt 9.
  • the two pile conveyor belts 8 and 9 are parallel to one another via the two Arms 3 and 4 out, so that they are able to cover and introduced a cushion web introduced between them on both sides, which ensures a gentle treatment.
  • a guide roller (without reference numeral) is mounted, over which the two web conveyor belts 8 and 9 are guided.
  • the two pile conveyor belts 8 and 9 separate at a first discharge gap S1 (see FIG Fig. 2 ) from each other, because they are there via separate guide rollers 10 and 11 and guided separately over the laying arm 4 and the feed 3 back into the region of the inlet E. They run in the region of the hinge axis 6 via an upper or lower guide roller 12 and 13, which are rotatably mounted there on a support frame.
  • the lower, free end of the laying arm 4 is connected to a carriage (here without reference numeral), on rails (not shown) horizontally above the delivery conveyor belt 7 is guided and connected to a drive device which consists of a toothed belt coupled to the carriage 14, a drive toothed disc 15 and a deflection plate 16.
  • the carriage carries two guide rollers 19 and 20, over each of which a cover strip 17 and 18 are guided, which serve to cover the laid fleece to avoid adverse aerodynamic effects in the pile storage.
  • the masking tapes form a second discharge gap S2 at their guide rollers 19 and 20 (see FIG Fig. 2 ).
  • Fig. 2 shows a section Fig. 1 in the region of the discharge slit S1 of the web conveyor belts 8 and 9 on the guide rollers 10 and 11 at the lower, free end of a laying arm (not shown).
  • the distance between each guide roller 10 or 11 of the web conveyor belts 8 and 9 and the opposite upper guide roller 19 and 20 of the cover strips 17 and 18 is preferably set so small that the bands just just touch, ie no open gap formed between them becomes. In this way it is prevented that in operation, the unavoidably forming due to the orbital motion of Florbansportb selected 8 and 9 forming air currents take a direction that could lead to an unwanted fiber fly out of the work area of the batt.
  • the width of the gaps S1 and S2 is set as a function of the pile thickness.
  • the width of the gap S2 can optionally also be adjustable as a function of operating conditions, as will be explained later.
  • the lower, inner runs of the cover strips 17 and 18 are the delivery conveyor belt 7 at a close distance and extend transversely to this.
  • Fig. 2 is not to scale with respect to this distance.
  • the masking tapes 17 and 18 each pass over guide rollers 21 and 22 on the delivery conveyor belt 7 over into a region under the same, where they are guided over lower guide rollers 23 and 24, which are pulled towards each other by means of a clamping device, the here by a tension spring 25 is symbolized.
  • the cover bands 17 and 18 are endless belts, and they can be set in motion by means of the guide rollers 21 and 22, respectively, at least one of which is connected to a drive device.
  • Such driven guide rollers 21 and 22 are in Fig. 2 represented by black and white sectors.
  • the two lower guide rollers 23 and 24 can in a carriage 27 (see Fig. 3 ), which is below the delivery conveyor belt 7 in a machine frame (not shown) transversely to the transport direction of the delivery conveyor belt 7 is movable.
  • Fig. 2 One recognizes in Fig. 2 in that alone by driving at least one of the guide rollers 21 and 22, the upper guide rollers 19 and 20 of the cover strips 17 and 18 can be moved to the left or right in the direction of arrow P, if at least one fitting of the other guide rollers is braked. If, for example, one brakes the guide rollers 21 leading the lower inner run of the cover strip 17 and drives the guide rollers 21 guiding the outer run of the same in a clockwise direction, the upper guide rollers 19 and 20 move to the right, turning clockwise. The two lower guide rollers 23 and 24 move simultaneously to the left.
  • FIG. 2 only shows the principal guidance of the pile conveyor belts 8 and 9 at their guide rollers and the cover strips 17 and 18 at their upper and lower guide rollers 19 and 20 or 23 and 24 and leaves open, as said rollers are mounted
  • Fig. 3 a practical first embodiment of the invention with an upper carriage 26 which is arranged above the delivery conveyor belt 7 in a machine frame (not shown) transversely to the transport direction of the delivery conveyor belt 7 movable and the guide rollers 10 and 11 of the Flortransportb selected and the upper guide rollers 19th and 20 of the cover strips 17 and 18 rotatably supports.
  • a toothed belt 14 is anchored, which is guided over a drive pinion 15 and a guide pin 16, so that with the aid of the drive pinion 15 of the carriage 26 in the direction of arrow P can be moved back and forth.
  • the lower guide rollers 23 and 24 of the cover strips 17 and 18 are rotatably mounted in a common lower carriage 27, which can be moved transversely to the transport direction below the delivery conveyor belt 7. Otherwise, the leadership corresponds to the cover bands 17 and 18 of the description Fig. 2 ,
  • the upper slide 26 can be moved back and forth with the aid of the toothed belt 14 without the upper guide rollers 19 and 20 of the cover tapes 17 and 18 having to rotate in the process.
  • the prerequisite is that all guide rollers 21 and 22 are freely rotatable.
  • the masking tapes 17 and 18 perform in such an operating case a movement transversely to the delivery conveyor belt 7.
  • the upper guide rollers 19 and 20 as the guide rollers 10 and 11 of the web conveyor belts 8 and 9 are driven in opposite directions such that the emerging from the first discharge gap S1 between the guide rollers 10 and 11 card web through the formed between the upper guide rollers 19 and 20 second Delivery gap S2 conveyed through and stored on the delivery conveyor belt 7. It is therefore necessary that the cover bands 17 and 18 in the gap formed by them have a component of movement in the direction of the delivery conveyor belt 7.
  • cover strips 17 and 18 are driven so that the peripheral speed of their upper guide rollers are slightly larger than the rotational speed of them adjacent to the guide rollers Flortransportbs Flortransportbs 8 and 9, so Flormaschinen after leaving the gap S1 about at adhere to the pile conveyor belts, are transported by the contact with the cover strips in the gusset between each conveyor belt and masking tape respectively formed gussets at greater speed from the gusset forth than in him.
  • the guide rollers must be connected to an independent drive device.
  • the 4 to 6 show a second embodiment of the invention in different operating conditions.
  • the embodiment of the 4 to 6 differs from the embodiment according to Fig. 3 characterized in that for the guide rollers 10 and 11 of the web conveyor belts 8 and 9 at the lower end of the laying arm only one of these guide rollers 10 and 11 associated carriage 26a is provided, while the upper guide rollers 19 and 20 of the cover strips 17 and 18 in a separate slide 26b rotatable are stored.
  • Both slides 26a and 26b are transversely to the transport direction of the delivery conveyor belt 7 in a machine frame (not shown) movable and connected to their own toothed belt 14a and 14b, respectively via a drive sprocket 15a and 15b and a guide sprocket 16a and 16b run.
  • braking and acceleration phases can be taken into account in the area of reversal of motion of the fleece laying process.
  • deceleration that is from the pile conveyor belts 8 and 9 fed card web on one side of one of the cover bands 17 and 18 and is stored.
  • this phase it makes sense to set a slightly higher speed of the Florabdeckb selected 17 and 18 in the gap S2 formed by them in comparison to the pile conveyor belts 8 and 9.
  • Fig. 4 shows an operating state during the normal movement of the laying member of the web laying over the delivery conveyor belt 7.
  • the two guide roller pairs 10, 11 and 19, 20 are arranged vertically one above the other. The opposite correspond to the Fig. 5 and 6 Operating conditions in the field of motion reversal of the laying body on the left and right edges of the delivery conveyor belt.
  • the carriage 26b which supports the upper guide rollers of the cover strips 17 and 18, is opposite to the carriage 26a, which defines the guide rollers 10 and 11 of the pile conveyor belts 8 and 9 stores, shifted to the right, so that the discharge column S1 and S2 are shifted from each other.
  • the card web merging from the gap S1 into the gap S2 is removed from the region of the gusset formed between the deflecting rollers 11 and 20 located in the direction of movement of the laying member, because there is a greater danger in that gusset that at the web transport belt 9 possibly adhering Florfasem be taken from this Flortransportband 9 through the gap between it and the cover 18, as in the other gusset formed between the guide rollers 10 and 19.
  • Fig. 6 represents the situation described above comparable situation in the reversal of movement of the laying member on the left edge of the delivery conveyor belt.
  • the mutual displacement of the two carriages 26a and 26b is compared to the situation in Fig. 5 vice versa. On a more detailed explanation can therefore be waived.
  • the mutual displacement of the carriages 26a and 26b can be produced in a very simple manner by appropriate control of the movement drives 15a and 15b, by means of which the toothed belts 14a and 14b anchored to the carriages 26a and 26b are driven.
  • the invention also makes it possible to produce a known transverse profiling of the laid pile. If the distances of the guide rollers 10 and 11 and the guide rollers 19 and 20 are set so tight that the pile is clamped in the columns S1 and S2, and one controls the drives of the guide rollers 21 and 22 of the cover strips so that their peripheral speed greater than the transport speed of the pile conveyor belts 8 and 9 is formed in the web track section between the columns S1 and S2, a train which leads to an elongation and thus elongation of the card web, which makes the pile thinner. By controlled variation of said speed difference as a function of the movement of the laying member, the thickness of the nonwoven fabric produced can be changed transversely to its longitudinal extension in any desired manner with the aid of the inventive nonwoven layer.
  • Fig. 7 shows a section of an embodiment of the invention, in which the distance between the carriage 26 b mounted deflection rollers 19 and 20 is adjustable during operation.
  • right deflection roller 19 is not mounted directly in the carriage 26b, but on sliding bodies 27, which in turn are slidably guided in the carriage 26b.
  • the sliding body 27 are connected to actuators 28 which are attached to the carriage 26b and can be realized for example by hydraulic or pneumatic cylinders.
  • the supply of such hydraulic or pneumatic drives prepares, especially when the nonwoven is realized as a low-arm leveler, no difficulties, since the supply lines for these drives can be guided along the arms of the steep-arm webbed and fastened.
  • the advantage of this measure is that, during operation, the width of the gap S2, which is formed between the cover strips 17 and 18 on the guide rollers 19 and 20, can be changed. It is thus possible to change the clamping effect on the guided between the gap S2 Flor depending on operating conditions of the laying member.
  • the gap S2 can be opened when, in the reversal of the direction of movement of the laying member, the pile of the system on a cover 17 on the system on the other cover 18 changes over, see in this context the Fig. 5 and 6 , If then the Flor covering band on the pile should call a ironing effect to smooth the pile after its filing, this band may need to be independent of the other, now idle cover band drivable.
