Definitions

  • the invention relates to a method and a device for detecting the mass of Fiber material in a spinning machine, the mass in the area of a feed roller Spinning position of a rotor spinning machine is detected.
  • Known rotor spinning machines have at the entrance to the spinning station or Spinnbox only a so-called feed trough, the incoming fiber material, which is in shape a tape is fed, presses against a feed roller, so that the fiber material of the feed roller is drawn in via the feed trough.
  • the food trough can be used as a kind Lever or flap that is rotatably mounted and located near the Feed roller extends approximately tangentially to this. After the feed roller it will Fiber material taken over by a dissolving roller, the fibers being separated.
  • measuring devices such as Measuring funnels, etc. can be connected upstream or downstream of the spinning station. But this can only be done be provided if there is space for a along the supplied fiber material Measuring device is available. If there is space, a measuring device can be used provide, but this creates resistance in the fiber material that must be overcome, and which may affect the fiber material in an unexpected way.
  • EP 0 275 471 which represents the closest prior art, is one Device known in which the mass of a sliver in a nip area between a food plate and a feed roller to be measured.
  • a disadvantage of this known device is the fact that the measurement of the mass takes place where the sliver for the purpose of increasing the friction between the feed roller and food plate is strongly compressed.
  • the feed roller can run out of round and on the other hand a local displacement of fibers due to said compression of the sliver falsify the measurement.
  • the solution to this problem is the mass of the fiber material in a measuring element to be recorded, which is offset with respect to the feed roller and assigned to a guide.
  • a suitable device has a measuring element that offset from the feed roller and in the area of a guide is arranged.
  • This measuring element can be designed as a touch element, which is arranged opposite a guide on the food trough.
  • Such measuring devices can Scan the surface of the fiber material and follow the bumps and deflections effect that are converted into a statement about a path or a pressure. Therefore these measuring elements have sensing elements which can be operated with a pressure gauge or a Odometers are connected.
  • Strain gauges in particular, are optical as the odometer or capacitive displacement transducers or pneumatic or piezoelectric ones Pressure transducer provided.
  • the Fiber material has to go through fewer elements, each of which is an inconvenient It can have an influence on it, and that on the other hand the spinning machine also has an element must have less so that the spinning station and its surroundings remain more accessible.
  • the measurement signals generated are particularly good for Control of the spinning station in the sense that it can be controlled directly so that fluctuations in mass in the fiber material in the spinning station itself due to the appropriate Regulation can be avoided. It also creates the possibility of before Processing to yarn to check the quality of the fiber material.
  • FIG. 1 shows a device with a feed trough 1, which here is limited around an axis 2 Areas are rotatably mounted and the one guide surface 3 for fiber material 5 has, which is arranged approximately tangentially to the circumference of a feed roller 4, as long as the feed trough is in a working position.
  • the feed roller 4 is connected downstream a dissolving roller 6.
  • guides 7 for the fiber material upstream provided that direct this to the feed trough 1.
  • the Probe 21 acts on a spring 23 which is provided with strain gauges. These are again arranged in a bridge circuit.
  • An evaluation circuit 24 with a Amplifier is also provided.
  • Figure 2 shows a comparable arrangement of the feeler 21 as in Fig. 1, this however, cooperates with a lever system 25 which controls the deflections of the sensing element 21 can increase or decrease, depending on how it is designed.
  • a Travel sensor 26 is provided for detecting the deflections of the lever system 25.
  • Figure 3 shows a system that works according to a passive pneumatic measuring principle. It therefore has an opening 27 in the guide 22 as a measuring element to the fiber material, which is connected to a pressure transducer 29 via a line 28. Line 28 is also connected to a feed line 31 via a pre-nozzle 30.
  • the pressure transducer 29 can be connected to a prechamber, as is already known from EP-A-0 750 060.
  • the pressure in the feed line 31 is preferably for all connected to it Food troughs right away.
  • FIG. 4 shows a system with a capacitive measuring element 42, which is on the guide 7 is arranged directly in front of the feed roller 4.
  • the capacity of the measuring element is in one Bridge circuit installed, which in turn is connected to an evaluation unit 41 now known type is.
  • the position of the sensing element 21 gives a measure of the thickness or mass of the fiber material 5.
  • the sensing element 21 is loaded by the spring 23 and is mounted so that it can be moved easily.
  • the deflection of the spring 23 is detected by the strain gauges in a manner known per se and output to the evaluation circuit 24.
  • the position of the guide 22 and its distance from the guide surface 3 must be set.
  • means which are not shown but are known per se are provided. Comparable processes take place in the embodiment according to FIG. 2.
  • the position of the guide 22 must also be set in the embodiment according to FIG. 3.
  • the pressure in the line 31 and the size of the nozzle 30 also play a role here in order to obtain an optimal mode of operation.
  • the feed trough 1 can be arranged in a fixed manner.
  • the Mass of the fiber material 5 fed as a sliver becomes as close as possible to the feed roller 4 measured in a known manner.
  • FIG. 5 on the axis 32 values for the mass of the Fiber material, on the axis 33 values of an electrical signal, for example in volts or ampere, a frequency or a digital signal and on the vertical axis 34 Values plotted that correspond to a physical quantity, e.g. Values one Correspond to an angle, a pressure, a force or a path. As a straight line 35 shows can assume between the latter values and the values of electrical signals that there is a linear relationship. On the other hand, it comes down to that Measuring principle on whether between the values that correspond to a deflection and the values which correspond to a mass, there is a linear relationship.
  • a curve 38 shows the 1
  • line 39 shows the connection shows pneumatically operating systems according to FIG. 3. From these characteristics 36 - 39 a work area can be selected in which the variations of the mass lie approximately by adjusting the guide 22 to the guide surface 1.
