Definitions

  • the invention relates to a needle machine according to the Preamble of claim 1. Such a machine is out DE 196 15 687 A1 known.
  • the needle bar a second drive assigned to it, which cyclically and synchronizes it with its Nonwoven fabric vertical penetration movement (vertical movement) in a swinging motion parallel to the nonwoven web (Horizontal movement) offset in and against Direction of transport of the nonwoven web through the needle machine runs and in time with the vertical puncture movement of the Needle bar is superimposed so that the movement of the needle bar in the horizontal direction in the period of each movement cycle, in which his needles are inserted into the fleece are those caused by the feed and take-off rollers Movement of the nonwoven fabric by the needle machine follows, while the needles are detached from the nonwoven, the return of the needle bar in the horizontal direction, i.e. parallel to the nonwoven web, in the starting position.
  • the needle bar thus leads from the side across to the transport direction seen the nonwoven web, a circular motion, depending according to the ratio of the strokes of the horizontal and vertical movements is more or less circular or elliptical.
  • the invention has for its object a drive Specify the type mentioned, with which the stroke of the transverse to Puncture movement of the needle bar directed movement that the Needle bar forced by the second drive device becomes, light and in fine gradation, preferably also stepless, is adjustable.
  • a first concept of the invention provides for the second drive device two eccentric shafts in front, with the same speed circulate and their connecting rod movements caused by them be combined on a coupling bridge.
  • Fig. 1 shows a simplified representation in the above sense a needle machine from the side.
  • two eccentric drives 2 are arranged, the one of Main motor O via belt, chain or similar drive connection driven, via connecting rods 3 a needle bar carrier 4 in can move up and down.
  • a needle bar carrier 4 in can move up and down.
  • To the Needle bar supports 4 are two each with needle boards 5 equipped needle bar 6 attached. From those on the needle boards 5 attached needles 7 are shown only a few.
  • the two Eccentric drives 2 are preferably by means of a gear connected, for example via a spur gear stage (not shown), around a synchronous counter-rotating movement of the eccentric drives to create.
  • the needles 7 pierce through a stripper 8 in one on one Base 9 lying nonwoven web (not shown), the in the example shown by means of powered feed and Draw rollers 10 and 11 is moved by the needle machine.
  • the coupling bridges 12 articulated, of which in Fig. 1st only one is shown.
  • the coupling bridges 12 have three Pivot points, namely first and second pivot points 13 and 14 at the ends and a third hinge point 15 in the middle.
  • the coupling bridges 12 are each with connected to the needle beam support 14, while at the first and second pivot points 13 and 14 the free ends of connecting rods 16 and 17 are hinged on one side of the Needle machine arranged eccentrics 18 and 19 and are driven by these.
  • the shafts of eccentrics 18 and 19 are from servomotors 20 or 21 via belts, chains or other suitable power transmission devices driven.
  • the servomotors, eccentrics, connecting rods and coupling bridges provide the second drive device for the needle bar represents.

  • the angular positions of the Waves known by angle sensors arranged on the shafts Type of detection and by means of the signals emitted by them the power supply to the electric motors that drive the shafts to control so that the desired mutual phase relationships the angular positions of the shafts can be reached.
  • control loops can be used based on the a target / actual comparison. Such control loops are generally known and need not be explained here.
  • a particular advantage of the solutions described above is that the adjustment of the stroke of the horizontal movement of the needle bar while the machine is running and therefore time-saving, without any disassembly, and can be carried out continuously can.
  • the scraper 8 and the pad 9 for the nonwoven web of the horizontal movement component of the Needles take into account.
  • the stripper 8 which consists of a Perforated plate consists of the holes for the passage of the Needles 7 are therefore designed as slots that extend in the direction the horizontal movement component of the needle bar 4 extend.
  • the pad 9 can be made in the same way as the scraper 8 be formed.
  • FIG. 2 shows a second embodiment of the invention, the that is very similar to FIG. 1 and only of this differs in that the two eccentrics 18 and 19 on different sides of the two needle bars 6 arranged are.
  • the construction of this machine is, as already from the drawing emerges, somewhat more compact than that of FIG. 1. There are no changes regarding the function, so that a detailed explanation is dispensed with can.
  • Fig. 3 shows an embodiment of the invention in which the Eccentric 18 and 19 of the second drive device above the Needle machine, i.e. are arranged at the head.
  • This embodiment is of particular interest in such applications, in which the footprint for the needle machine is limited, but sufficient above the needle machine Assembly room is available.

  • the scraper 8 and the pad 9 but do not follow the vertical movement of the needle beam carrier 4 because they are in the second guide slots 64 located guide flanges 63 are hindered.
  • the vertical movement of the needle beam carrier 4 is by wipers 8 and Pad 9 is not hindered because its bent ends 62 in slide the first guide slots 61.
  • FIG. 5 schematically shows a plan view of the needle bar area a needle machine. Needle machines sometimes have a lot large working widths that can be several meters. To the to avoid adverse influences of inertia, which too elastic deflections of the needle bar could result, if the force attack on the needle bar only at one point 5, it is provided that the horizontal Movement component of the needle bar at several along its Extension is distributed places. 5 are elements corresponding to the examples explained above provided with the same reference numerals so that they are not repeated here need to be explained. You can see that from the hinge point 15 of the coupling bridge 12 starting from the eccentrics 18th and 19 caused movement via a wishbone 25 and several rocker arms 26 and a corresponding number of trailing arms 27 is transferred to the needle beam carrier 4. This construction principle can be easily based on the embodiment Fig. 3 transferred.
  • FIGS. 1 and 2 would be along the Needle beam carrier 4 several, arranged on a common shaft, identically aligned eccentrics with a corresponding one Number of connecting rods to be provided over several coupling bridges grasp the needle bar support.
  • this tracking movement has a horizontal direction a speed curve that is sinusoidal, i.e. the Horizontal speed of the needle bar gradually decreases from zero increases, reaches a maximum and then decreases again to zero then the direction for the return movement of the needle bar to reverse, etc.
  • speed of the horizontal movement of the needle bar carried needles on the speed of the feed movement the nonwoven web penetrated by the needles, which in particular Cases when, for example, felts of special fineness and Uniformity, such as paper machine felts, to undesirable disturbances in the structure of the manufactured product.
  • the invention proposes a further development before, the servomotors of the second drive device in one to control the cyclically running program in such a way that the aforementioned sinusoidal velocity profile of horizontal movement of the needle bar at least in that horizontal movement stroke, which follows the direction of web advance to a uniform one Speed is smoothed.
  • Modern control electronics allows the speed of rotation of servo motors in this Way to influence.
  • the needle machine directly assigned feed and To dispense with discharge rollers or between the roller pairs formed column wider than the thickness of the nonwoven web to make and therefore the nonwoven web alone with the help of needles pierced into it by the from the second Drive device caused horizontal movement of the To move the needle bar through the needling zone.
  • a sinusoidal course of the horizontal movement of the needle bar is even an advantage in this case because it creates a "Plucking" on the nonwoven web through the needles when accelerating is prevented in the horizontal direction.
  • the complete Adjustment of the needle movement in the horizontal direction to the Enabling respective needs will result in a significant increase in quality of the manufactured product.
  • Another Increase in quality by comparing or blurring the stitch pattern can be achieved if the needle bar between successive stitch movements laterally, i.e. across to the fleece feed direction by less than one lateral Needle spacing is offset.
  • a drive scheme for generation such a lateral movement of the needle bar is also shown in Fig. 5.
  • the control of the servomotor 52 takes place in that phase Vertical movement of the needle bar carrier 4, in which the needles 7 are not pierced into the nonwoven web.
  • the range of motion that must be produced by the actuator 52 is relative small. According to a lateral distance between each other adjacent needles is usually about 3 mm he just a little less than 3 mm. This range of motion is appropriate divided into several, for example two stages, so that each needle is between three lateral positions is adjustable, a left, a middle and a right Position, seen in the direction of web advance. These positions can be used cyclically, for example either after every needle insertion or after a predetermined one Number of needle punctures in the nonwoven web Position is changed using the servomotor 52.
  • the corresponding Control of the servomotor 52 thus takes place in Coordination with the work cycle of the eccentric drives 2 and can, in particular, use the angle encoder that may be installed there and possibly clock counters.
  • the control of the servomotor 52 can expediently via a control generator 53 take place, which processes a cyclically running control program or a stochastic random sequence of control commands for the servomotor 52.
  • FIG. 6 Another possibility, which is shown in Fig. 6, consists of the actuator being driven by an eccentric drive two eccentrics 54 synchronized by independent drive motors 55 are driven and their connecting rods 56 at the ends a coupling bridge 57 are coupled to each other to form.
