  "abstract": "A melt spinning device for producing synthetic threads includes at least a spinneret apparatus, a cooling apparatus, a processing apparatus and a winding apparatus. An automatic operating device is provided for carrying out at least one operator action. The automatic operating device has at least one movable robotic arm, which can be coupled selectively to one of a plurality of exchangeable tools in order to selectively carry out a plurality of operator actions during a start-up and/or during a maintenance interval and/or during thread production. Thus, a high level of flexibility in the automated operation of the melt spinning device is ensured.",
  "claims": [
    "1. Melt-spinning device for producing synthetic threads, having at least one spinning nozzle installation, having at least one cooling installation, having at least one treatment installation, having at least one take-up winding installation, and having at least one movable robotic operator for carrying out at least one operator activity, wherein the robotic operator has at least one movable robotic arm which for selectively carrying out a plurality of operator activities during commissioning and/or during a maintenance interval and/or during the production of thread is selectively couplable to one of a plurality of interchangeable tools, wherein the tools are kept ready in a tool magazine disposed on the robotic operator, wherein one of the tools is a suction injector installation by way of which one or a plurality of threads is/are guidable to a waste container, and wherein one of the tools is a gripping installation by way of which one or a plurality of packages and/or one or a plurality of package tubes is/are guidable.",
    "2. Melt-spinning device according to claim 1, wherein the robotic arm for retrieving and for dispensing the tools interacts with the tool magazine.",
    "3. Melt-spinning device according to claim 1, wherein one of the tools is a measuring installation by way of which one or a plurality of product parameters is/are measurable.",
    "4. Melt-spinning device according to claim 1, wherein one of the tools is a camera installation by way of which one or a plurality of thread runs in the installations is/are monitorable.",
    "5. Melt-spinning device according to claim 1, wherein the robotic operator is configured so as to autonomously travel on a suspended track which extends along a plurality of treatment installations and take-up winding installations.",
    "6. Melt-spinning device according to claim 1, wherein the robotic operator for carrying out the operator activities has a robot control apparatus, and in that the robot control apparatus is connected to a machine control installation.",

  "description_excerpt": "The invention relates to a melt-spinning device for producing synthetic threads as disclosed herein.\n\nA melt-spinning device of the generic type for producing synthetic threads is known from EP 1 300 496 A1, for example.\n\nThe known melt-spinning device for producing a plurality of synthetic threads has a spinning nozzle installation, a cooling installation, a treatment installation, and a take-up winding installation, said installations being held in a machine frame so as to form a thread run. The spinning nozzle installation is disposed on an upper level above the treatment installation and the take-up winding installation. In order for a thread group that has been generated from the spinning nozzle installation to be threaded up on the sets of the treatment installation and of the take-up winding installations when a process is started, a robot which is moved vertically and horizontally by a guiding installation is provided. An additional doffer, which for changing the packages in the take-up winding installation is likewise embodied so as to be vertically and horizontally movable, is provided. To this extent, it is necessary in the case of the known melt-spinning device that the motions of the robot and of the doffer have to be mutually adapted in order for specific operator activities to be carried out. In particular in the case of process interruptions in which changing a package and fresh threading-up is necessary, there is the risk of collisions between the robot and the doffer.",
