Definitions

  • the invention relates to a method for stopping a electric drive motor, especially one Drive motor for driving a grooved drum Winding station of a winding machine, which is used for braking in opposite directions a braking current is applied to a nominal current, whose strength can be a multiple of the nominal current, and a brake circuit.
  • the invention has for its object a method and to create a brake circuit of the type mentioned, in which the element driven by the drive motor or the associated machine work with the highest possible efficiency can.
  • this object is achieved by that the current thermal load of the Drive motor detected and the strength of the braking current dependent from this thermal load on the drive motor is selected.
  • graded values for braking currents are stored, each of which an area is assigned to a thermal load. For such a step-by-step implementation is sufficient Determination of the suitable braking current without further ado.
  • the object is achieved by that means for detecting the current thermal load of the drive motor and means for selecting the for a braking current to be applied in dependence are provided by this thermal load.
  • the individual winding units are included a grooved drum 10 equipped during the rewinding a relatively large-volume package on friction drives.
  • the Groove drum 10 one of one (not shown) Spinnkops pulled thread 12 in the transverse direction that a conical or cylindrical cheese 11 is wound.
  • the grooved drum 10 is driven by an electric motor 13 driven, which is an electronic in the embodiment commutated servo motor.
  • the circuit arrangement with the Brake circuit according to the present invention is suitable however, in principle for any type of electrical Drive motor.
  • the winding process is interrupted immediately. That is, the cross-wound bobbin 11 is lifted from the grooved drum 10 and braked to a standstill by means of a bobbin brake, which is not shown but is known per se and is arranged on the bobbin frame.
  • the grooved drum 10, which has a not inconsiderable weight inertia, is also braked by applying braking current to the associated drive motor 13, which is directed in the opposite direction to the current direction of the nominal current present during normal winding operation.
  • a braking current with the highest possible strength is selected, which can be a multiple of the strength of the nominal current.
  • the thermal load which occurs briefly is not so strong that it can damage the drive motor 13.
  • thermal overload when braking To avoid downtimes caused is in accordance with Invention provided that the current thermal constantly Load of the drive motor 13 is detected, and that in Depending on the strength of the braking current for the following braking process is selected so that it ensures is that there is no thermal overload. So that will not with the shortest during every braking operation theoretically possible braking time braked, but it does Brakes with the technically shortest, a thermal Overloading the drive motor 13 avoiding braking time.
  • a winding station computer 14 specifies the current strength and current direction with which the drive motor 13 is acted upon.
  • the winding unit computer 14 determines the speed of the drive motor 13 on the one hand and, on the other hand, its braking behavior depending on the thermal load state of the drive motor 13.
  • the winding unit computer 14 processes information from a central computer (not shown) which is sent to it, for example, via a machine bus 21. This information can relate, for example, to the winding speed or the rotational speed of the drive motor 13, possibly also to achieve image disturbances to avoid image winding on the cheese 11.
  • the signals from the winding station computer 14, which reach a power amplifier 15 via a line 22, are processed there accordingly.
  • the output stage 15 passes the current in phase to the windings of the drive motor 13.
  • the output stage 15 also uses information from a rotor position sensor 16.
  • the actual speed or actual speed of the drive motor 13 detected on a pole ring 17 of the drive motor 13 is reported back to the winding station computer 14 for speed control.
  • the detected actual speed of the drive motor 13 can also be used for further functions at the winding unit, for example it can be passed to a cleaner which determines the measuring intervals for monitoring the thread 12 depending on the actual speed.
  • the winding unit computer 14 also evaluates the information about the current thermal load on the drive motor 13. As indicated in FIG. 1, a thermal sensor 18 can be assigned to the drive motor 13, the signal of which is input into the winding unit computer 14.
  • the winding station computer 14 can also calculate the instantaneous thermal load on the drive motor 13 by detecting the current applied to the drive motor 13 over time.
  • the winding unit computer 14 has an integrator 20 and a memory 19. A large number of drum load value ranges with their associated braking values are stored in the memory 19.
  • the winding unit computer 14 determines the strength of the braking current with which the drive motor 13 can be subjected to a maximum for each braking operation in such a way that the shortest possible braking time is achieved, but the braking current does not lead to an inadmissible thermal overload of the drive motor 13 ,
