  • similar jobs means units that can simultaneously perform a defined work process. It goes without saying that it can happen during operation of the textile machine that one or more of the similar jobs are in a different phase of the work process, as other jobs. For example, some of the jobs may be in one production phase, others may be in a phase of preparation for the production phase and some may be in a dormant phase.
  • the said working process is typically a spinning process, ie a production process for a yarn, which may comprise winding the yarn produced on a bobbin, for example a cross-wound bobbin, or a bobbin winding process, ie a process for producing a bobbin of prefabricated yarn.
  • the workstations are arranged side by side on both longitudinal sides in textile machines.
  • Each workstation has the essential components that are required to carry out the work process. However, it is not necessary that the jobs are absolutely identical. Thus, for example, individual workstations can be equipped with additional sensors for detecting certain variables, which only have to be recorded once per group or section.
  • Communication is generally understood to mean the exchange of information which serves to control and / or monitor the production of the textile machine.
  • information consists of interpretable values.
  • the corresponding information is transmitted on the physical level by signals, for example by electrical signals.
  • Such signals can be, in particular, sensor signals which contain information about the production process of the textile machine and control signals which contain information for influencing the production process. They may also be operator signals representing commands that can be entered by an operator via an operator, as well as observation signals intended to monitor production by an operator.
  • Such signals can be present as analog signals with a continuous range of values, as digital signals which can only assume discrete values, or as binary signals with only two value states.

  • Each of these communication-capable functional units is connected directly to the section CAN bus.
  • the increase in the number of participants usually leads to a physical extension of the bus, which may be designed for example as a two-wire or three-wire line. This is especially true when it is necessary to dispense with spurs in order to avoid consequent changes in the characteristic impedance along the bus, since in this case the bus must be passed to each participant.
  • the maximum bandwidth decreases, ie the maximum speed of the information transmission.
  • the combination of a high number of subscribers with a low bandwidth significantly increases the risk of information congestion on the section bus.
  • time-sensitive sensor or control information may also be transmitted only with delay or late. Concerning.

  • the control information to be transmitted to the respective motor which includes the states "on” and “off” and the specification of a desired speed, is represented by the amplitude and / or frequency of the control signal, which is converted by the respective motor 14 into a rotational speed , Therefore, no further control device is provided on the motors 14.
  • a predetermined by the processor 37 binary control signal is transmitted, which makes it possible to turn on or off the waxing 21 a.
  • the binary control signal may, for example, actuate an electrical coupling which holds the paraffin block holder 21 (see FIG FIG. 2 ) connects to and separates from a machine-long drive shaft. The energy for driving the paraffin block holder 21 therefore does not need to be provided by the group control means 35a.
  • the coil lifts 24 can be raised or lowered by means of the lines 36a3, 36b3, 36c3 and 36 d3 transmitted binary control signals, for example, by a pneumatic cylinder is controlled.
  • the actual drive energy for the coil lifts 24 is provided by a compressed air source, so that the binary control signal only has to have a low power.
  • the processor 37 is further for evaluating signals from the sensors 20, which transmit via the lines 36a4, 34b4, 34c4 and 36d4 from the sensors 20 of the spinning units 3a to 3d to the group control device 35a become. Therefore, it is possible to dispense with evaluation electronics at the spinning stations 3a to 3d. Since the lines 36a4, 34b4, 34c4 and 36d4 transmit sensor data, they may also be called data lines.
  • the spinning stations 3a and 3c are arranged on a first longitudinal side 38a of the textile machine 1.
  • the spinning stations 3b and 3d are arranged on the opposite longitudinal side 38b.
  • the group control device 35a is provided in a central region 39, which extends between the first longitudinal side 38a and the second longitudinal side 38b.
  • FIG. 6 shows a modification of the basis of the FIG. 5 explained embodiment.
  • the spinning units 3a to 3d are also connected to the associated group control means 35a via independent communication paths 36a to 36d.
  • Each of the communication paths 36a to 36d includes a communication bus 40a to 40d.
  • the communication-capable functional units 4, 9, 10 and 8 each one of the spinning units 3a to 3d and the group control device 35a are connected.
  • black double arrows cutting clamps are used.
  • the communication buses 36a to 36d each take over the data transport between the group control device 35a and exactly one of the spinning units 3a to 3d. They are preferably designed as linear CAN buses with double-sided terminating resistors.
  • the actuators 13, 21 and 24 of a particular spinning station 3 via a communication bus 40 with the group control device 35a and the sensor 20 of the spinning station 3 with a direct independent line to the group control device 35a be connected.
  • FIG. 7 Another embodiment shows FIG. 7 , Independent communication paths connecting the group controller 35a to each of the spinning units 3a to 3d are not provided here. Rather, the communication between the functional units 4, 9, 10 and 8 of the spinning units 3a to 3d via a group-wide group bus 41. Again, this is preferably a linear CAN bus with two-sided terminating resistors. The central line of the CAN bus is guided directly along each of the communication-capable functional units 4, 9, 10, 8 of the spinning stations 3 a to 3 d to be connected, so that the connection of the communication-capable functional units can take place directly via insulation displacement terminals. Cutting clamps for connecting functional units to the group bus are also shown here by black double arrows. Their different length results only for drawing reasons.
  • the sensors 20 of the workstations 3a to 3d via a group bus 41 with the section control device 35a and the actuators 14, 21a, 24 by means of independent communication paths 36 may be connected to the group controller 35a.
