Definitions

  • the invention relates to a device for picking up a web material and dispensing it with a speed that fluctuates over time, but on average matches the speed of picking up, according to the preamble of claim 1.
  • Such a device is known from US 5 590 442.
  • the known device serves as a pile storage between a working at a constant discharge speed pile fabricator and a working with changing speed recording nonwoven layer, which is designed as Horizontalleger (so-called. Flachtäfler).
  • Horizontalleger so-called. Flachtäfler
  • the pile memory is controlled according to the rotational speed of the laying belts of the web laying, which varies with the rhythm of the absolute driving speed of the laying carriage.
  • the known pile memory consists of a U-shaped extending web portion of variable length of an endlessly circulating conveyor belt which extends between a pile fabricator and the nonwoven and feeds the delivered from the pile fabric Flor the unwoven.
  • the conveyor belt faces an endlessly circulating pressure belt, which is guided around a first deflecting roller and covered there by the conveyor belt and which continues to run around a second deflecting roller, which is arranged parallel to the first deflecting roller.
  • the two guide rollers are rotatably mounted in a common frame, which is mounted transversely to the roller axes in a machine frame in the plane described by the axes of the two guide rollers.
  • the pressure belt In the U-shaped web section of the conveyor belt, the pressure belt is located close to the conveyor belt and is thus able to clamp the pile brought up by the conveyor belt.
  • the guide rollers holding the frame ie by changing the depth of immersion of the pressure belt in the U-shaped path portion of the conveyor belt, the length of the path that must take the pile between the pile generator and the nonwoven, changeable, so that a certain length of Flor can be cached if necessary.
  • the pile memory is thus able to match the uniform pile delivery speed of the pile fabric with the uneven pile picking speed of the batt layer.
  • the invention has for its object to provide a device of the type mentioned, which is structurally simple.
  • the guide roller which guides the two parallel conveyed conveyor belts on a variable length portion, together with two guide rollers over which the return portions of the conveyor belts run, stored in a common frame which is movable to the one of the two to change the storage buffer sections formed in parallel in its storage volume.
  • the storage of said frame can be made very simple. You can mount it on a movable carriage or hang it, for example, like a pendulum on a relatively long-arm handlebar. Any sliding guides are then unnecessary. It when the frame is pivotally mounted on the carriage or the handlebar is particularly advantageous. Is in this case in the path of one of the conveyor belts a Tensioning roller arranged, it is possible with their help to tension both conveyor belts, since the voltage of a conveyor belt is transmitted via the pivotally held frame to the other conveyor belt.
  • Such a construction is particularly advantageous in installations in which the storage device is combined as a pile buffer with a steep-arm leveler so that the conveyor belts of the buffer run continuously to the deposit of Flors at the free end of the laying arm of the batt and thus the pile store and connect the nonwoven layer integrally with each other.
  • Such a machine combination is also an object of the present invention. She has the advantage over a Flachtäfler that the pile is clamped on its entire path from the inlet to the cache to the filing on the deposit belt continuously between two parallel conveyor belts and is thus protected against any delay in this way.
  • first arm 2 also referred to as a feed arm
  • second arm 3 which is also referred to as a laying arm
  • the feed arm 2 is articulated at its lower end in the aforementioned machine frame, not shown.
  • the lower end can be moved by means of a stationary drive 4 and a toothed belt 5 across a deposit belt, of which in the drawing a guide roller 6 is shown schematically.
  • the depositing belt extends perpendicular to the direction of movement of the lower end of the laying arm 3 to the guide roller 6.
  • a cover 7 is connected, which is guided over a plurality of guide rollers 8 and extends over the depositing belt to the movement of the devisrms 3 caused turbulence at the delivery site B to keep away from the laid fleece and avoid wrinkling in the fleece.
  • a pile store 9 of variable volume is shown.
  • the pile memory 9 is essentially formed by two conveyor belts 10 and 11, which pass through the pile memory 9 and are also guided over the arms 2 and 3 of the skiving-fleece layer 1.
  • the two conveyor belts 10 and 11 together determine a receiving location A, at which one of a pile fabricator (not shown) and to be laid by the nonwoven layer 1 card web (also not shown) is inserted into a gap between the two conveyor belts 10 and 11.
  • the conveyor belts 10 and 11 extend as a pair via a first deflecting roller 12, a drive roller 13, a further deflecting roller 14 and over the arms 2 and 3 of the deflecting armature 1, in which the two arms 2 and 3 connecting joint over a guide roller 15 are guided.
  • the two deflection rollers 16 and 17 together determine a delivery location B, at which the pile brought up by the fleece layer 1 is deposited by reciprocating pivoting movements of the arms 2 and 3 from the laying arm 3 on the laying belt.
  • the conveyor belt 10 runs via a deflecting roller 18 arranged in the joint area of the arms 2 and 3, after leaving the feeding arm 2 via a further deflecting roller 19, a drive roller 20 and from there in a substantially U-shaped path whose vertex is formed by a deflecting roller 21 further guide roller 22 and a drive roller 23, where the location A is located.
  • the wide conveyor belt runs over a deflection roller 24 located in the articulated region of the arms 2 and 3 and after leaving the feed arm 2 via a deflection roller 25, a drive roller 26, a U-shaped path section, in the apex of which a deflection roller 27 is located, a deflecting tension roller 28 and a drive roller 29, which is located at the recording location A.
  • the guide rollers 21 and 27 located in the above-mentioned vertexes of the U-shaped path sections of the returning conveyor belts 10 and 11 are rotatably mounted in a frame 30 on which the first guide roller 12 is mounted to guide the paired leading sections of the conveyor belts 10 and 11 to run.
  • the frame 30 is pivotally mounted in the axis of the guide roller 12 on a frame-shaped link 31, which is shown in the drawing only schematically with a dash-dotted line and in a pivot bearing 32 in the machine frame (not shown) is suspended.
  • the deflecting tension roller 28 is attached to the tension arm of a hydraulic cylinder 33.
  • the tensile force applied by the hydraulic cylinder 33 to the tensioning roller 28 tensions the conveyor belt 11 and transmits via the deflection roller 27 and the frame 30, which acts as a two-armed lever and pivots about the axis of the deflection roller 12 common to the conveyor belts 10 and 11, via the deflection roller 21 to the return section of the other conveyor belt 11.
  • both conveyor belts 10 and 11 can be tensioned.
  • the conveyor belts 10 and 11 pass over a plurality of guide rollers 34 mounted on the arms, some of which rest alternately on one and on the other side of the paired outgoing conveyor belt sections to cause the conveyor belts to flutter Poor 2 and 3 to avoid.
  • the frame 30 remains in its state shown in Fig. 1.
  • the peripheral speed of the drive roller 13 becomes greater than that of the other drive rollers, the drive roller 13 pulls the frame 30 to the left in FIG. 1 via the paired conveyor belts and the guide roller 12, thereby shortening the length of the flow leading portions of the conveyor belts 10 and 11.
  • the length of the returning portions of the conveyor belts 10 and 11 is increased, since the deflection rollers 21 and 27 mounted on the frame 30, from which the return sections of the conveyor belts are deflected in a U-shape, are also moved to the left. Places moved to the left of the guide rollers 12, 21 and 27 are shown in dashed lines in the drawing with 12 ', 21' and 27 'located.
  • the frame 30 moves in Fig. 1 to the right, so that the guide rollers 12, 21 and 27 in the in Fig. 1 with 12 ", 21" zw.
  • the conveyor belts 10 and 11 remain tensioned.
  • the length section which the conveyor belts 10 and 11 determine between the receiving location A and the delivery location B can thus be changed. It is thus possible to temporarily change the speed of the delivery of the pile at the delivery location B in relation to the rate of receiving the pile at the location A.
  • This change is necessary in the fleece layer 1, because the speed at which the delivery point B, ie the lower end of the laying arm 3, moves over the depositing belt, can not be constant, because in the range of movement reversal points of the laying arm 3 whose speed has to braked to 0 and accelerated in the opposite direction again.
  • the laying arm 3 would continue to deliver the pile at a constant speed, then thickenings would result in the edge region of the nonwoven web laid by the fleece layer 1, but this must absolutely be avoided. It is therefore necessary to vary the speed at which the nap is released from the laying arm 3 in accordance with the moving speed of the laying arm 3 via the laying tape.
  • This variation of the delivery rate of the web from the nip between the idler rolls 16 and 17 at the discharge location B can be accomplished by proper control of the drive rolls 13, 20 and 26 with respect to the drive rolls 23 and 29, in which case the frame 30 is essentially one oscillating movement about the pivot point 32 performs, which moves the guide rollers 12, 21 and 27 between the points 12 ', 21' and 27 'on the one hand and the points 12 ", 21" and 27 "on the other hand back and forth and thereby the cached pile volume cyclically changed.
  • Both can be achieved with the aid of the tension roller 28, which is under the influence of the hydraulic cylinder 33, which pulls the tension roller 28 to the right in FIG. 2, which causes the frame 30 from its position shown in Fig. 1 in the counterclockwise direction is pivoted on the handlebar 31 in the position shown in Fig. 2.
  • the return section of the conveyor belt 11 is shortened, at the same time the return section of the other conveyor belt 10 is extended.
  • the laying width is 3,500 mm.
  • the length of the arms 2 and 3 between the guide roller 24 and the ends of the arms is about 2,800 mm.
  • the conveyor belts have a length of 21,500 mm each.
  • the path of travel of the steep-arm leveler 1 is 4,000 mm.
  • the laying arms In the retracted state of the arms 2 and 3, which is shown in Fig. 1, the laying arms enclose an angle of about 27 °, while in the extended state, which is shown in Fig. 2, an angle of about 133 °.
  • the inequality caused by the different arm positions of the yielding of the conveyor belts, due to the change in the wrap angle on the guide rollers 19 and 25, is compensated by an adjustment of about 200 mm of the tension roller 28 by the hydraulic cylinder 33.
  • the frame-shaped link 31, on which the frame 30 is suspended has an effective length (pendulum length) of 1,400 mm, while the distance between the guide rollers 21 and 27 on the frame 30 of the conveyor belt common guide roller 12 is 520 mm.
  • a space of about 2,100 mm in length before the steep-arm leveler 1 and about 1,750 mm in height, including the handlebar assembly 31 is required.
  • the common deflecting roller 12 mounted on the frame 30 could be designed as a drive roller, while the roller 13 is a free-running deflecting roller. It could also be mounted on the frame 30 guide rollers 21 and 27 drive rollers, while the rollers 20 and 26 are free-running guide rollers.
  • the frame 30 could instead be suspended from a handlebar 31, pivotally mounted in a movable carriage.
  • the nonwoven layer could have four articulated arms which are movable in the manner of a lattice grate, in order to prevent an increase in the height of the fleece layer.
  • the conveyor belts would then be paired over all four arms, so that the pile is always held in its entire path by two tight conveyor belts.
