Definitions

  • the invention relates to a melt spinning device for the production of synthetic threads according to the preamble of claim 1.
  • Synthetic threads are produced by melt spinning devices which have a large number of spinning positions.
  • the spinning positions are set up side by side to form a longitudinal machine front in a machine hall.
  • Each of the spinning positions has a spinneret device with several spinnerets for extruding several threads.
  • the threads of a spinning position are pulled together from the spinning nozzles as a family of threads by a godet device and, at the end of the process, wound up in several winding positions of a winding device parallel to bobbins.
  • the winding devices of the spinning positions are each equipped with two winding spindles held on a winding turret, so that the threads in the spinning positions are continuously produced.
  • auxiliary devices are preferably formed by an operating robot which is guided movably along the longitudinal machine front and can optionally be fed to one of the spinning positions for the application of the threads.
  • a melt spinning device is disclosed, for example, in EP 3 312 120 A1.
  • the operating robot is designed to be movable in order to selectively move to the individual spinning positions.
  • the operating robot has a spinning position on a suction injector, which continuously picks up the thread sheet and leads to an empty waste container.
  • the operating robot has a coupling adapter which is connected to a waste line and a compressed air line of the suction injector.
  • the coupling adapter can be coupled to one connection per spinning position in order to connect the waste line to a central waste line and the compressed air line to a central compressed air line.
  • the central compressed air line which extends over all spinning positions, is connected to a central yarn waste container.
  • the known melt spinning device has the disadvantage that the waste lines have to cover large distances and therefore require relatively high pressures of the compressed air. Because of the high compressed air consumption associated with it, the known melt spinning device is uneconomical in terms of energy.
  • melt spinning device Another disadvantage of the known melt spinning device is that an exact positioning of the operating robot is required both for coupling the compressed air and the waste line in the spinning position and for taking over and guiding the threads with the suction injector. Within the spinning position, however, the position of the compressed air connections is independent of the position of the godet device and the winding machine on which the threads are to be placed. This is why the robot's conditions are inevitable.
  • This object is achieved according to the invention in that the compressed air line and the waste line are connected to a supply car and in that the supply car is guided on the monorail.
  • the invention has the particular advantage that the positioning of the operating robot only has to be adapted to the respective position of the winding device and godet device. It is customary for such winding devices to be replaced regularly for maintenance purposes. This means that slight changes in position within the spinning position can occur, which can be taken into account without problems when positioning the operating robot.
  • the connection to a supply car allows the operating robot to be flexible. A coupling of the compressed air line and waste line between the operating robot and one of the spinning positions can be omitted.
  • the supply trolley is equipped with a yarn waste container which is connected to the waste line. This allows the thread group picked up by the suction injector to be picked up in a short way.
  • compressed air settings with relatively low overpressures for guiding the thread sheet within a spinning position can be implemented.
  • the thread waste container has a cyclone-shaped inner structure for receiving thread thread, through which the thread waste is helical is discardable. In this way, tangled shelves and thread interlacing within the yarn waste can be avoided. In addition to the very compact filling of the yarn waste container, there is also the advantage that removal and emptying of the yarn waste container is simplified.
  • the refinement of the melt spinning device is preferably carried out, in which the yarn waste container has a movable waste flap on the underside of the supply trolley for opening and closing and that the waste flap is coupled to a controllable swivel actuator is. So there is the possibility of emptying the thread waste by simply opening the waste flap from the empty waste container.
  • each of the spinning positions is assigned one of several connection stations, each with a compressed air connection for compressed air transmission, which is arranged with one on the supply carriage Connection adapter interacts.
  • the supply car can advantageously be automatically connected to a compressed air supply in each of the spinning positions, which is fed into the compressed air line of the operating robot.
  • the supply car and the operating robot are guided together by a conveyor on the monorail.
  • the operating robot is quickly ready for operation in each of the spinning positions in order to be able to pick up the thread family of one of the spinning positions and to carry out the threading.
  • two separate funding means are assigned to the supply car and the operating robot, through which the supply car and the operating robot can be guided independently on the monorail.
  • This further development of the invention has the particular advantage that the operating robot and the supply car can be positioned independently of one another.
  • the operating robot can thus be adapted to the conditions of the godet device and the winding device of the respective spinning position.
  • the supply trolley on the other hand, can be adapted to a connection station for the relevant spinning position.
  • the development of the invention is provided in which the compressed air line and the waste line are designed to be coupled between the operating robot and the supply trolley.
  • the compressed air line and the waste line between the supply car and the operating robot can be disconnected or connected via simple plug connections.
  • the operating robot In order to be able to carry out all activities for taking over a family of threads and for applying and guiding a family of threads with great flexibility, the operating robot has a controllable robot arm which guides the suction injector and a cutting device at one free end. Due to the free mobility of the robot arm, very high degrees of freedom for thread handling are achieved.
