Definitions

  • the present invention relates to a needling machine and an associated advance control method.
  • a needling machine The purpose of a needling machine is to consolidate mechanically a sheet of fibers from a spreader-lapper or any other system and passing between two perforated steel plates called table respectively and stripper.
  • This layer of fibers is crossed by needles generally placed on a support referred to as needle boards.
  • the stripper stands opposite the plank hands which is driven in an alternating movement.
  • the needles successively enter the stripper, in the fiber sheet and in the table, then perform a reverse route over a needling period during from which the fiber web moves a distance called not in advance.
  • the fiber layers are driven in the needling machine upstream by a introducer consisting of a first pair rollers and downstream of the needling machine, by a extractor device comprising a second pair of rollers.
  • the object of the invention is to remedy these disadvantages of offering a needle loom that is designed to allow speed modulation angle of the extraction rollers during each needling period, this modulation can be of variable amplitude until a zero angular acceleration.
  • a needling machine comprising means for switching according to a variable strike frequency a passing sheet of fibers usually between two perforated steel plates one first pair of rollers to introduce the sheet of fibers between the two plates with a speed of substantially constant introduction, a second pair rollers to extract the sheet of fibers at the outlet plates, means for training the means needling in a periodic striking movement, control and processing means related to these needling drive means and means electromechanical to drive variable speed extraction rollers.
  • the electromechanical means training and means of control and treatment cooperate to provide speed modulation angle of the extraction rollers around a speed average extraction, this modulation being of amplitude variable, in synchronism with the periodic movement needling means and at a frequency equal to the strike frequency.
  • a needling machine it becomes possible to predict, thanks to the implementation of electromechanical means with variable speed, one slowing of the sheet of fibers during needling, which cannot be reduced to a simple stop in advance. Indeed, with the present invention, it does not more then stop-start sequences, which limits the acceleration value of the water table, but by real modulation of the extraction speed, which goes allow to increase the striking frequencies. Moreover, the introduction means are kept at speed constant while the extraction means are modulated in speed, which has the effect of allowing a continuous treatment of the fiber web. Otherwise, the setting of the extraction speed can be controlled by software, which contributes to flexibility of use that would be difficult to obtain with mechanical devices of the prior art. Furthermore, it becomes possible to easily change the amplitude of modulation, for example as a function of average speed extraction, in particular to reduce the amplitude when the average extraction speed is increased.
  • the present invention makes it possible to provide for a stop or at least a slowdown in resources extraction during the needling phase. So the extraction speed during a period needling can be adjusted, depending on the type of needled product and needler row concerned in a line of machines.
  • the synchronism with the movement needling can be anticipated or delayed to account for elasticity and amortization of the textile web and dynamic characteristics of the drive system.
  • This discontinuous advance scheme obtained by modulation angular velocity is particularly suitable for products with a relatively stiff texture or to be used in the first machines of line.
  • the means electromechanical rotating and control means and co-operate to provide modulation of the angular speed of the extraction rollers, this modulation with a deceleration sequence substantially coinciding with a needling sequence.
  • the means electromechanical rotating and control means and further cooperate to provide a modulation of the advance step of the layer of fibers around of a constant average step of advance according to an amplitude slightly variable.
  • the means electromechanical revolving devices consist of one or several geared motors slaved in position.
  • These gearmotors can include a synchronous motor to permanent autopilot magnets, or a motor asynchronous with vector flow control, or any other engine technology that may be used implemented within a geared motor.
  • a method for controlling the advance of a sheet of fibers in a needling machine characterized in that it comprises a servo of position of the needle roller and an adjustment of their angular speed.
  • the angular speed adjustment includes modulation around an angular speed medium, this modulation having a frequency of modulation equal to the strike frequency and being performed in synchronism with the periodic movement of needling means so that the needling of the fiber sheet substantially coincides with a phase of slowing down of the advance thereof.
  • the angular velocity modulation has an amplitude such as the angular speed of the extraction rollers cancels during the tablecloth needling sequence fiber.
  • the method may further include adjusting the phase difference between the speed modulation cycles angular and typing cycles.
  • a method for ordering the advance of a needling machine according to the invention characterized in that it further includes modulation of the advance step of the sheet of fibers around an average pitch, this modulation being performed at a submultiple frequency the frequency of the needling machine.
  • This process can be combined with the above process and thus include a angular speed modulation.
  • This feature allows the result of impacts of the needles on the product, i.e. the sum of several different steps combined, which allows operate at an average step ahead, the result textile could be bad in itself and that would would find improved by this accumulation of steps around this step way.
  • This method implementing a modulation of the pitch in advance is particularly suitable for needling products for which the visual aspect is important or still to be used in needle looms finish.
  • a needling machine 1 comprises two perforated parallel plates 3, 7 designated respectively under the term table (bottom plate) and stripper (upper plate), between which moves a sheet of fibers 2 from another machine (not shown) located upstream of the needling machine 1, for example a spreader-lapper.
  • This layer of fibers 2 is driven within the needling machine 1 thanks to a part, to introducer means 17 comprising generally a pair of rollers 18, 19 driven constant speed and located at the head of the needling machine 1, and, on the other hand, to extractor means 10 produced generally in the form of two rollers 15, 16 which are driven by a speed drive variable 12.
  • the needling machine 1 further comprises a set of needle boards 5, 6, for example at number of two, which are subject to movement alternative perpendicular to the plane of the table and stripper by means of a drive device alternative 4 located on the upper part of the needling machine 1 and comprising for example assemblies crank rod.
  • a drive device alternative 4 located on the upper part of the needling machine 1 and comprising for example assemblies crank rod.
  • each plate 5, 6 is driven in a vertical movement descending until needles 8 enter the perforations of the stripper 7, in the fibers of the tablecloth 2 which is then slowed down or even immobilized and in the perforations of the table 8.
  • the movement of needles continues with a rise out of the water table of fibers 2.
  • This sheet is subject to displacement sequential defined by a step ahead which is the distance traveled between two needling sequences.
  • the extraction rollers 15, 16 are driven by a electromechanical variable speed device 12 comprising a geared motor assembly 124, and a variator 120 power electronics.
  • the device electromechanical 12 is controlled by a control unit and processing 11, associated with interface means usual 13 such as a display monitor and a keyboard, this unit 11 also controlling the device alternative drive 4.
  • the gearmotor assembly includes an electric motor 121 and a reduction gear mechanical 124 intended to adapt the nominal speeds common of an electric motor at low speeds required for driving the extraction rollers 15, 16.
  • These extraction rollers must be slaved to both in speed and in position, which requires practice the use of position coding means 14 which are connected to the electronic dimmer to provide this variator information on the instantaneous position rollers.
  • a first advance control mode implemented in a needling machine according to the invention such as the above-mentioned needling machine 1, with reference to FIGS. 2A to 2C.
  • the instantaneous angular speed ⁇ of the extraction rollers 15, 16 is modulated on each striking cycle according to a modulation waveform 20, 21, for example a sine waveform, around an average angular speed ⁇ m .
  • This average angular speed must be chosen with respect to the speed of introduction so that it corresponds to an average flow of product extracted equal to the average flow of product introduced.
  • the needles 8 penetrate the stripper and the fiber sheet with a delay time ⁇ b while the extraction rollers are already stopped or have exceeded their point of maximum deceleration. During the withdrawal of the needles, the extraction rollers are again driven.
  • This type of control is suitable for products with a relatively stiff texture implying needle penetration at zero or very low feed speed.
  • the needles 8 penetrate into the stripper and into the fiber web with a time of advance ⁇ c with respect to the instant of stop or maximum deceleration of the extraction rollers. This advance allows withdrawal of the needles at very low speed of movement of the sheet of fibers.
  • the control and treatment 11 controls the drive device electromechanical 12 so as to obtain a modulation 30 of the step P of the needling machine 1 around a step constant mean advance Pm.
  • the modulation period is in practice chosen equal to a high number k of periods typing or needling Ta, in order to standardize the distribution of needle impacts on the water table fibers.
  • Typing sequence F includes cycles elementary strikes corresponding to an alternation of high positions H of the needle boards and low needling positions A.
  • the advance step P is directly proportional to the average speed of advance and therefore to the average speed of rotation of the extraction rollers which can be easily adjusted in a needling machine according to the invention.
  • a first modulation 40 is performed at a first modulation frequency equal to the strike frequency (period Ta) and corresponds to a synchronous slowdown or cyclic stop with needling, while a second modulation 31 affects the average angular velocity and corresponds to a second modulation frequency generally very low in front of the striking frequency and equal to the frequency of modulation of the advance step P around the average step Pm.
  • the extraction rollers can be driven by any type of engine or geared motor without any other conceptual limitation that the need for sufficient performance in terms of torque / inertia ratio.
  • We can thus consider driving by reluctance motors variable or hybrid motors.
  • We also may also provide mechanical devices indirect drive of the extraction rollers from a single geared motor.
  • the profiles of modulation can be adapted to the products to switch, at the required rates and type needling machine selected.
