Definitions

  • the invention relates to a device on a spinning preparation machine, z.
  • a device on a spinning preparation machine for measuring distances between the garnished flat bars of a moving lid unit and the garnished drum, in which at least one sensor is present, with the tip spacing (carding) between the garnished surfaces can be detected, the sensor is associated with a flat bar and the Drum set is arranged opposite.
  • the DE4235610 A1 discloses a sensor for measuring the carding distance, wherein the sensor is associated with the lid and the clothing is opposite to the drum.
  • the invention is therefore an object of the invention to provide a device of the type described above, which eliminates the disadvantages mentioned, which allows in particular a non-contact carding gap measurement under production conditions and allows wireless transmission of the measured data to an evaluation.
  • the at least one sensor is integrated in the flat bar and there is wireless signal transmission allows the carding nip to be measured during fiber material throughput production.
  • a further advantage is that it allows the wireless signal transmission in combination with the integration of the measuring electronics in a further flat bar that the card remains closed and all safety devices remain in operation. As a result, even a simple trained user can use the measuring system.
  • the device according to the invention makes it possible to continuously determine the carding gap on the revolving lid without contact during production, that is to say without influencing the measurement result by means of fiber material. Furthermore, the card is operated by the system under real conditions, for example with closed doors. Since the carding gap is particularly dependent on the temperature conditions in the card, there is a difference between a measurement with open and closed doors, as this changes the temperature conditions.
  • Fig. 1 shows a card, z. B. Trützschler carding TC, with feed roller 1, dining table 2, lickers 3a, 3b, 3c, drum 4, pickup 5, skimmer 6, nip rollers 7, 8, Vliesleitelement 9, trimming funnel 10, take-off rollers 11, 12, revolving lid 13 with Deckelumlenkrollen 13a , 13b and garnished flat bars 14, jug 15 and can stock 16.
  • M denotes the center point (axis) of the drum 4.
  • 4a indicates the set (Sägeyakgarnitur) and 4b indicates the direction of rotation of the drum 4 at.
  • 5a indicates the set (saw tooth set) and 5b indicates the direction of rotation of the pickup 5.
  • the measuring cover rod 14d contains the sensors 18a, 18b, 18c (see FIG. Fig. 7 ) for temperature and carding gap measurement, while the transport cover 17 includes the electronics, power supply and data transmission. These two elements are connected to each other via cable lines 19, while the data from the transport cover 17 wirelessly to an evaluation unit 20 (see FIG. Fig. 6 ) are transferred outside the card.
  • the dimensions of the transport cover 17 are selected such that the boards of the eddy current sensors are used without problems can. Due to the significant deviation of the design of the transport cover 17 of a normal flat bar 14, it is not possible to use 17 left and right next to the transport cover 17 normal flat bars 14. At these positions, two intermediate lids 21a, 21b are provided. The intermediate covers close the gaps between the transport cover 17 and the adjacent flat bars 14, so that no fibers are blown out of the pressurized Kardierspalt at these locations.
  • a toothed belt for the transport of the flat bars 14a to 14n and the transport cover 17 in the direction B is designated.
  • the flat bars 14a to 14n are made of extruded aluminum and each have a cavity 14 'on.
  • the transport rod 17 according to Fig. 3 as a carrier of the electronics and power supply, is not bound to the design of a flat bar 14a to 14n. Part of the concept is to accommodate all required components of the Meßdeckelsystems in a transport rod 17.
  • the transport rod 17 should not interfere with the carding, but since no measurements are made, deviations from the normal flat rod 14a to 14n are possible.
  • the basic shape of the transport cover 17 includes a housing 17 1 with an internal cavity 17 second
  • the housing 17 1 is mounted on the cover foot 14 "(full profile) of a milled flat bar 14a to 14n .
  • the dimensions of the profile interior 17 2 enable the reception of the required electronic components. Under production conditions, this means that no carding work is performed when used in the carding zone at three successive topmost card places. Fig. 3 ) intended.
  • each eddy current sensor requires its own board 24a, 24b and 24c, added to the system electronics 25, a (not shown) common electronics of the six temperature sensors, the power supply via an accumulator 26 and a Bluetooth module 27th
  • FIG. 5 are the two intermediate rods 21a, 21b, left and right of the transport cover 17, milled flat bars 14a to 14n. To increase the rigidity of the flat bar in each case a bridge from the right or left side has stopped. The shape of the intermediate rods 21a, 21b results from the deflection of the transport cover in the lid circuit.
  • the transport cover 17 requires the space of three flat bars 14a to 14n. So that no fibers are blown out in front of and behind the transport cover 17 in the carding zone, the two intermediate rods 21a, 21b cover the intermediate spaces.
  • the milled profile, each with a web is the allowable space that can be claimed by the intermediate rods 21a, 21b.
  • the transport cover rod 17 includes the housing 17 1 and the cover foot 14 ".
  • the complete measuring system is in Fig. 6 shown. It consists of the measuring cover 14d, the transport cover 17, the two intermediate covers 21a, 21b and a laptop 20 for displaying and evaluating the measured values.
  • Fig. 7 For the use of the measuring system are after Fig. 7 from the existing lid circuit of the revolving lid 13, sh. Fig. 1 taken a card four flat bars 14a to 14n.
  • the transport cover 17 with the two intermediate lids 21a, 21b requires a blank space of three flat bars in Episode.
  • the measuring lid 14d In the running direction B of the flat bars, the measuring lid 14d is inserted by two or three positions in front of the transport lid 17, so that the measuring lid 14d moves into the active carding zone in front of the transport lid 17.
