Definitions

  • the invention relates to a nonwoven laying device with a nonwoven layer and a variable storage volume arranged on the inlet side thereof according to the preamble of claim 1.
  • a nonwoven laying device is known from EP 0 659 220 B1.
  • the nonwoven layer is a so-called flat saw, which has a superstructure and a laying carriage, the respective guide rollers for two endlessly circulating.
  • Carry pile conveyor belts The two Flortransportb selected are guided on their path over both cars and limit between the car path sections for the Flortransport in which the Flor is guided on both sides of the Flortransportbsn.
  • the pile On the path leading to the superstructure, the pile lies loosely on the first conveyor belt and is not covered by the roll of the superstructure which deflects this conveyor belt either.
  • the pile passes through two places, where it is also supported only on one side, here from the second pile conveyor belt.
  • the arranged before the nonwoven fabric pile storage variable volume is a separate unit that stores variable amounts of fleece and controls the nonwoven laid temporarily more or less Flor, since the Flortransportb S have due to the laying movements of the laying carriage in operation changing rotational speeds.
  • the pile storage has a holding frame which rotatably supports two mutually parallel deflection rollers at a distance from each other. To these two guide rollers an endlessly circulating Antikband is looped.
  • the support frame is arranged in the path of the upper strand of an endlessly circulating conveyor belt, which leads from a card as a pile generator to the nonwoven, so that in this path a U-shaped detour is formed, the length of which depends on how far the support frame in the otherwise substantially straight running path of the feed belt is immersed.
  • the returning lower strand of the feed belt is guided over a two guide rollers carrying carriage, which moves in opposite directions to the movement of the holding frame in operation.
  • the pile is therefore not supported in this area. For sensitive florets, this can lead to a delay. Because the pile subsequently rests only loosely on the first pile conveyor belt of the web laying machine, fluttering of the pile on the pile conveyor belt can occur at high pile feeding speeds.
  • the invention has for its object to provide a nonwoven laying device of the type mentioned, which ensures a gentle treatment of the deposited pile on its entire transport from the inlet of the storage bin to the deposit on the delivery conveyor belt.
  • the invention is characterized by two essential features, namely that the pile is guided on both sides between pile conveyor belts on its entire way through the nonwoven laying machine, without there being places where the pile would have to be transferred unprotected from one piece of tape to another.
  • Another important feature is that at least one of the pile conveyor belts also passes through the pile store, so that the pile fed into the pile store is supported by this at least one pile conveyor belt also in that area where the pile leaves the pile store and enters the lapper.
  • both pile conveyor belts of the web laying machine are guided through the pile store, so that the pile is continuously guided between two pile conveyor belts on its entire path from the feeding zone of the pile store to the pile tray on the delivery conveyor belt.
  • the invention thus immediately has the advantage that problems of a coordination of drives in the pile storage and in the nonwoven layer do not arise a priori, since one and the same pile conveyor belt or both pile conveyor belts run or run through both devices.
  • the device according to the invention consists, according to FIGS. 1 and 2, of a fleece layer 1 and a pile store 2 arranged in front of the inlet E of the fleece layer.
  • the fleece layer 1 is a Steilarmvliesleger having a feed arm 3 and a laying arm 4, which are hinged together.
  • the feed arm 3 is pivotally mounted about a lower 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 a Flor introduced between them on both sides and support, 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 from each other, because they are there via separate guide rollers 10 and 11 and separated over the laying arm 4 and the feed 3 back. They run in the region of the hinge axis 6 via an upper or a lower guide roller 12 and 13, which are rotatably mounted there on a support frame.
  • a carriage which is on rails (Not shown) is guided horizontally above the delivery conveyor belt 7 and connected to a drive device which consists of a coupled to the slide toothed belt 14, a drive toothed disc 15 and a deflection plate 16.
  • the carriage carries two guide rollers, over each of which a cover strip 17 and 18 is guided, which serve to cover the laid fleece to avoid adverse aerodynamic effects in the pile storage. This should not be discussed further here.
  • returning portion of the first Flortransportbandes 8 is guided over a tension roller 19 which is wrapped by it by about 180 ° and which is under the bias of a hydraulic or pneumatic clamping cylinder 20. From the tension roller 19 of the returning portion of the first Flortransportbandes 8 runs via a stationary mounted, driven guide roller 21 and a stationary mounted guide roller 22 back to the feed 3 as a delivery conveyor belt 7 running Flortransportbandabêt.
  • the returning section of the second pile conveyor belt 9 runs from the feed arm 3, via a driven guide roller 23, a tension roller 24, which is wrapped by it by about 180 ° and is under the influence of a hydraulic or pneumatic clamping cylinder 25, in the direction of the pile memory. 2
  • the pile memory 2 has a holding frame 26, in which three guide rollers 27, 28 and 29 are mounted at a distance parallel to each other in a common plane rotatable.
  • the holding frame 26 is mounted in the plane spanned by it transversely to the axial direction of the guide rollers 27 to 29 adjustable in a machine frame, which is indicated by dashed lines.
  • the adjustment of the support frame 26 is indicated by the double arrow P.
  • an endless pressure belt 30 is wound, which is also guided over a Walzentripel from two lateral guide rollers 31 and 32 and a central guide roller 33 which are mounted laterally of the frame 26 near this stationary.
  • the middle deflection roller 33 is connected to a drive and is located in the closest possible proximity to the deflection roller 22, around which the first pile transport belt 8 is wound on its way to the feed arm 3.
  • the returning portion of the second pile conveyor belt 9 extends from its tension roller 24, starting over the third, mounted in the support frame 26 guide roller 29, the it wraps around about 180 °, to a fixed guide roller 34 and from there to a feed zone A of the storage tank 2, where there is a driven guide roller 35. From there, the second pile conveyor belt 9 runs to a fixedly mounted Umlenkwalze 36, which is mounted adjacent to the pressure belt 30.
  • a pile fed to the feed zone A is always guided between two belts from the inlet to the pile store 2 in the area of the drive belt 36 deflecting the second belt conveyor belt 9 until it is deposited at the free end of the laying arm 4, namely in the pile store 2 between the second pile conveyor belt 9 and the pressure belt 30 to the middle guide roller 33 of the rolling center, and from the first web transport belt 8 deflecting roller 22 between the second pile conveyor belt 9 and the first Flortransportband 8.
  • the pile is supported on one side only by the second pile conveyor belt 9. But this area is so short that the there can not be damaged.
  • the pile adheres very well to the second pile conveyor belt 9 due to the preceding contact pressure.
  • the task of the storage tank 2 is, as in the prior art, the change in the transport speed of the pile conveyor belts 8 and 9, which is caused by the laying movement of the laying arm 4, of a uniform Florzu slaughter with which the pile is supplied for example by a card, to decouple.
  • the pile delivery from the laying arm 4 must be reduced in the area of the reversal points at the edges of the delivery conveyor belt 7, because the movement of the laying arm 4 there has to be braked. Otherwise, a uniform pile delivery on the part of the laying arm 4 would have the consequence that thickenings result at the edges of the fleece formed on the delivery conveyor belt 7.
  • two driven deflection rollers are provided in the path of the second pile conveyor belt 9 upstream and downstream of the storage unit 2, namely the guide rollers 23 and 35, whose peripheral speeds are decoupled from each other.
  • the driven guide roller 35 runs at the feed zone A at a uniform peripheral speed.
  • the circumferential speed of the deflection roller 23 located on the other side of the storage space 2, and with it also the peripheral speed of the drive roller 21 deflecting the first conveyor belt 8 is controlled as a function of the laying movements of the laying arm 4.
  • the peripheral speed of the driving rollers 23 and 21 must also be reduced.
  • the detour loop of the second pile conveyor belt 9, which is formed by means of the third guide roller 29 on the holding frame 26, must be reduced.
  • the length of the U-shaped detour loop increases, which is formed by the storage element 2 with the aid of the second deflection roller 28 with corresponding movement of the holding frame 26, so that the storage volume in the storage element 2 is increased.
  • less pile is discharged from the pile memory 2. If the laying arm 4 accelerates again, the reverse process takes place.
  • the pile memory 2 can continue to be used in a conventional manner to compensate fluctuating Florzu 1990 Bulgariaen.
  • fluctuating Florzu 1990 Bulgariaen arise, for example, when between a uniformly working pile generator and the crosslapper a drafting arrangement (not shown) is arranged, which cyclically stretched the card web supplied to him to produce thin points therein, which are to be stored in the edge region of the delivery conveyor belt 7. It is favorable in this case, when the holding frame 26 of the storage folder 2 with a drive device (not shown) is connected, which controls the storage volume increases and decreases.
