Definitions

  • the invention relates to a method and a device for regulating the basis weight or strip weight of the end product of a fiber processing machine according to the preamble of claims 1 and 2 respectively.
  • a box feeder with scales is known from DE 39 13 733 A1, which e.g. can be upstream of a card.
  • the scale has a device for measuring the instantaneous weight of a supplied fiber mat and a device for measuring the speed of the supplied fiber mat.
  • the aim of the known control method is to enable a constant mass discharge of the scale at the card input.
  • the known control method only sees a constant keeping of the supplied fiber mat in front of the card in front. The result of this is that when the fiber-processed system starts up or runs down, a considerable amount of scrap is produced before the desired basis weight or strip weight of the end product is reached. Furthermore, the known method does not make it possible to take into account the interference effects of the fiber processing machine.
  • the invention has for its object to provide a method and a device for regulating the basis weight or strip weight, with which the basis weight or strip weight of the end product can be maintained with greater accuracy at the outlet of a fiber processing machine or a fiber processing production line, with which the set-up times for a batch or product change can be reduced and with which the scrap production during the run-up and run-down of the fiber processing plant can be reduced.
  • the invention advantageously provides that the control as a first input parameter, the measured value of the system speed at the outlet of the fiber processing machine or the control a target value for the basis weight or strip weight at the outlet of the fiber processing machine or a further machine downstream of the fiber processing machine one of the fiber processors Subordinate machine downstream machine can be entered as a second input parameter and a correction parameter as a third input parameter.
  • the correction parameter captures textile-technological influences, such as flight suction, working width restriction, finishing job, edge suction and climatic influences.
  • the control also receives the continuously measured actual value of the amount of spinning material supplied per unit of time via the belt weigher. From the input parameters, the control calculates a setpoint for the regulation of the feed speed at the inlet of the first fiber processing machine in comparison to the actual value of the amount of spinning material supplied.
  • the invention enables less weight fluctuations in the end product, e.g. Nonwoven or tape in the longitudinal direction.
  • the set-up times are considerably reduced because the basis weight desired at the outlet of the fiber-processing machine or the fiber-processing system is regulated and can thus be set in a very short time by the control system.
  • the production of rejects is reduced during the run-up as well as during the run-down of the production plant, since the regulation also takes place with changing production speeds.
  • Another important advantage of the invention is that it is the prerequisite for automation of the production process of a fiber processing machine as well as complete production plants.
  • a card or card 1 as a fiber processing machine receives a fiber mat via a feed device 2, which is fed to the feed device 6 of the fiber processing machine 1 with the aid of a weighing device 4, for example an electronic belt scale known per se.
  • the electronic belt scale allows the basis weight of the fiber mat to be measured with an accuracy of 1 - 2%.
  • the fiber mat is conveyed on an endless belt 12 to the feed device 6, a measuring device 14 being located in the middle below the belt section carrying the fiber mat, which determines the weight of the fiber mat on the weighing section A.
  • the basis weight P ist is entered into the controller 10, taking into account the width of the incoming fiber mat together with the actual belt speed V ist determined with the aid of a tachometer generator 16.
  • the amount of spinning material supplied per unit of time then results as the actual value from the product of the actual value for the weight per unit area on the weighing device 4 and the belt running speed.
  • the amount of spinning material is adapted to the desired basis weight or strip weight of the end product.
  • the feed device 6 is driven by a controllable motor 18 which is controlled by a controller 20.
  • a tachometer generator 22 detects the feed speed of the feed device 6.
  • a tachometer generator 28 detects the outflow speed of the fiber material and inputs the speed value as input parameter V into the controller 10.
  • a further input parameter P is manually entered into the control 10 via an adjusting device 30 for the nominal value of the basis weight or strip weight at the outlet of the fiber processing machine 1.
  • a third parameter K is entered into the controller 10 with the aid of a setting device (not shown).
  • This correction parameter has the task of taking plant-specific, textile technology and / or climatic influences into account.
  • Such influences are, for example, flight suction, edge suction, working width constriction, finishing job, climate changes.
  • influencing factors can be automatically detected and entered using suitable sensors.
  • Empirical values e.g. with regard to the influence of climate changes, can be stored in a memory area of the controller 10 and can be called up.
  • the target value for the basis weight or strip weight can also relate to the outlet of a machine downstream of the fiber-processing machine 1, for example a nonwoven strip layer.
  • the speed of the end product at the outlet table will be the following Machine measured and entered into the controller 10.
  • the method is based on the constant acquisition of the input parameters in comparison with the weight and speed signals of the continuous weight measuring system of the weighing device 4.
  • the controller 10 generates a setpoint signal Y which controls the speed-variable feed drive 18.
  • the fiber processing machine 1 can be started as needed.
  • the preset basis weight is reached after the corresponding throughput time of the fiber processing machine 1. It can be adjusted at any time to another desired basis weight with the setting device 30.
  • the belt running speed of the belt 12 and / or the speed of the feed rollers of the feed device 2 can also be controlled accordingly by the controller 10 for the purpose of adapting the amount of spinning material supplied.
