Definitions

  • the invention relates to a device for monitoring a yarn moving in its longitudinal direction, with a measuring head and an evaluation unit that is spatially separated from and connected to the measuring head.
  • a device for monitoring and / or measuring parameters of a running, wire or thread-like test material in which a capacitive as well as an optical measuring element is arranged in a measuring gap.
  • the two measuring elements form two measuring zones that can overlap each other.
  • the measuring head has a first part, for example working according to a first measuring principle, which is connected via a connection to a first part of an evaluation unit for evaluating the signals from the first part, for example according to the first measuring principle.
  • a second part of the measuring head for example working according to a second measuring principle, can be connected to the first part of the measuring head via a detachable connection.
  • the evaluation unit also has a second, second part connected via a detachable connection for evaluating signals from the second part, for example according to a second measuring principle.
  • the measuring head and evaluation unit can also include third and further parts.
  • the advantages achieved by the invention can be seen in particular in the fact that the production of such devices can be further standardized, because there are only a few matching measuring heads and evaluation units, some of which have the same dimensions.
  • one measuring system can monitor the uniformity of the yarn and the other measuring system the foreign fibers or foreign substances in the yarn.
  • Another advantage is that physical quantities that are measured in either part of the measuring head or occur in any other way do not influence each other.
  • Each part can be specifically and specifically designed to record a certain textile size. Then it is also possible to derive further textile-related variables when evaluating the signals from the parts of the measuring head.
  • a certain "three-dimensional" measurement of the yarn can be achieved with the aid of such derived sizes, parameters such as the volume, the density, the structure of the yarn etc. being able to be determined.
  • FIG. 1 for a yarn 1, a first part 2 of a measuring head can be seen, on which the yarn 1 is moved past in a measuring gap 3 in a manner known per se.
  • the first part 2 has a connection 4 with a plug connection for a connection 5 to a first part 6 of an evaluation unit 7.
  • the evaluation unit 7 is shown here only schematically by its carrier plates, on which electronic components are arranged, which form an evaluation circuit, in a manner known per se but not shown here.
  • the first part 2 of the measuring head also has a connection 8 for a plug connection to a second part 9 of the measuring head.
  • a counterpart 10 for connection 8 is provided in the second part 9, a counterpart 10 for connection 8 is provided in the operational state.
  • the second part 9, lying on a side surface 11 of the first part 2 is mechanically detachably connected to the latter, for example via screw connections 12, 12, 13, 13 ', 14, 14' and 15, 15 '.
  • the electrical connection of the two parts 2 and 9 of the measuring head takes place via the plug connection 8, 10.
  • the outer shape of the measuring head with its two parts 2 and 9 is preferably chosen and dimensioned such that an attachment to the spinning and winding machines known today such as so far a single sensor can be made.
  • a further part 19 can also be attached to the first or second part.
  • a comparable structure is provided in the evaluation unit 7, in which the first part 6 and a second part 16 are also electrically connected via a plug connection 17 and mechanically via plug or screw connections not shown here.
  • the two parts 6 and 16 can also be accommodated in a common housing 18, of which a part is indicated schematically here.
  • the structure can be expanded to include other parts.
  • the most varied of parameters such as the mass of the yarn, uniformity of the yarn, foreign matter content or foreign fiber content of the yarn, etc., per se be determined in a known manner.
  • the first part 2 of the measuring head it is also possible to use the first part 2 of the measuring head to determine a first parameter, for example the mass of the yarn, and the second part 9 to determine the foreign fiber content of the yarn.
  • the first and second parts 6, 16 of the evaluation unit 7 are also designed to determine these parameters.
  • the evaluation unit 7 is designed in a manner known per se for evaluating electrical signals which are emitted by one or more parts 2, 9 which operate optically, capacitively or on a further principle. It converts these signals into measured values.
  • FIG. 2 shows an embodiment of the device at the work stations 20, 21, 22, 23, 24 of a spinning or winding machine, a first part 25, 26, 27, 28, 29 of a measuring head via a line 30, 31, 32, 33, 34 are connected to a single, common first part 35 of an evaluation unit.
  • This also has a common second part 36 for second parts 37, 38, 39, 40, 41 of the measuring heads.
  • the second parts 36-41 are detachably connected to the first parts 25-29 and 35.
  • a measuring head system can be constructed which provides base parts 2, 6 for frequently requested measurements and additional parts 9, 16 for more specific or less frequent measurements.
  • the base parts 2, 6 and the additional parts 9, 16 form apart from the connection to one another and possibly their supply in mechanical and electronic terms autonomous units.
  • a single work station or a machine with additional parts can also be temporarily equipped to handle a special task. By exchanging the additional parts between individual work stations or machines, it is also easier to find out whether an error has occurred on the measuring system or on the machine. So the machines can be equipped with such measuring head systems gradually, which allows the textile industrialist, with less Participation in ongoing technical progress in the field of measuring and monitoring yarn.
