Definitions

  • the invention relates to a method and a device for supplying liquid preparation agent to running threads at workplaces of a spinning machine, in particular a drawing twine, draw-winder or twisting or winding machine or a texturing machine, according to the preamble of claim 1 and claim 5. It is a so-called thread preparation device, the task of which is to ensure an even application of preparation agent at a large number of work stations of the aforementioned machines.
  • Preparation devices which have a driven preparation roller which runs in a tub partially filled with preparation agent (DE-PS 29 39 281).
  • the thread to be treated touches the preparation roller over part of its circumference during the course of the thread and is wetted in the process.
  • this preparation roller is surrounded by a cover.
  • Such preparation devices have a number of disadvantages; for example, the dosing accuracy of such devices is relatively low.
  • there are Facilities are very difficult to accommodate due to their relatively large space requirement and contamination of the entire machine cannot be completely ruled out despite the encapsulation.
  • a distribution system for wetting liquid which has a delivery unit, a compensation device and contactors connected to the compensation device via supply lines (DE-OS 24 33 507).
  • the feed lines are all of the same length; the contactors of the same distribution system are arranged at the same height.
  • Capillary tubes are preferably used as supply lines. This facility is complex and costly.
  • the prior art from which the invention is based, includes a method (US Pat. No. 3,648,650) in which control means for regulating the pressure of the gas pressure cushion are provided within a container containing the preparation agent.
  • the object of the present invention is to provide a method and an apparatus of the type mentioned at the outset which, in a cost-saving manner, ensure a uniform distribution of the preparation agent on the running threads at every work station of a spinning machine.
  • This object is achieved in that the normal volume of the gas pressure cushion remains unchanged and that the pressure of the gas pressure cushion is adjusted and kept constant by regulating the supply of preparation agent to the container.
  • This has the advantage that, with a cost-saving structure, a sufficiently equal pressure from one job to another is ensured in a simple manner. With the same line cross-section, the same line length and the same nozzle bore, the same flow rate is achieved at all preparation points.
  • the supply of preparation agent to the container can be regulated in accordance with the pressure of the gas pressure cushion. Alternatively, there is the possibility that the supply of preparation agent to the container is regulated according to the level of the preparation agent in the container.
  • a device for carrying out the method with at least one distribution container arranged in the area of the machine is defined in claim 5: the gas pressure cushion is constant in volume, there is a pressure source and means for regulating the supply of preparation agent according to the pressure of the gas pressure cushion or the height of the preparation agent.
  • the gas pressure cushion is constant in volume, there is a pressure source and means for regulating the supply of preparation agent according to the pressure of the gas pressure cushion or the height of the preparation agent.
  • a pressure control device with a pressure sensor for sensitive adjustment and for keeping the pressure in the distribution container constant is provided.
  • the pressure source can be designed as a pressure medium pump or as a pressure medium storage, for example as a pressurized gas bottle.
  • a preparation agent pump is arranged between the distribution container and the storage container, by means of which preparation agents are conveyed into the pressurized distribution container can.
  • the storage container can be designed as a refill container from which fresh preparation agent is refilled, or as a reflux container from which the returning preparation agent is fed again.
  • the refill container is designed to be pressure-tight and can be pressurized by a gaseous medium to convey the preparation agent into the distribution container.
  • the pressure source acting on the distribution container can also be connected to the storage container via a branch line.
  • the preparation can advantageously be sucked out of the distribution container, whereby the supply lines from the distribution container to the nozzles are also automatically emptied.
  • a stretch-twisting machine generally designated with the position number 1 is shown in a schematic side view.
  • threads 2 run via a pair of rollers 3 to godet drives 4 and via thread guides 5 to spools 7 attached to spindles 6.
  • a preparation agent 11 which is located in a distribution container 10, is fed to the threads 2 via nozzles 8.
  • This distribution container 10 is designed to be pressure-tight and is connected to lines 9 of the same length, preferably connected to the distribution container 10 in the bottom region calibrated, same nozzles 8 in connection.
  • the distribution container 10 contains the preparation agent 11, on which a pressure cushion formed by a pressurized, gaseous medium acts.
  • the container 10 is connected to a pressure source, for example a pressure medium reservoir 12 filled with compressed air or a pressure medium pump 27 (FIGS. 3, 4).
  • a metering valve 14 for metering the pressure in the system and thus the supply of the preparation agent to the preparation sites is preferably arranged in the connecting line, and maintains the predetermined pressure of the gaseous medium as part of a control device.
  • the pressure medium pump 27 can be designed as a controllable unit (FIG. 4).
  • the distribution container 10 is about half filled with preparation agent 11, and refilling is possible.
  • the gaseous medium which was introduced into the distribution container 10 from the pressure source, acts on the preparation agent 11 with a certain excess pressure.
  • Collection trays 15 are arranged below the nozzles 8 and are connected to a collection container 16 via lines 17.
  • the distribution container 10 is connected via a line 19 to a storage container 20 which is designed as a refill container 20 '.
  • a preparation agent pump 21 and a manually operated shutoff valve 22, which is closed when the refill container 20 is replaced.
  • a valve 23 for regulating the fill level of the distribution container 10.
  • This valve can be manually operated and serve to maintain the level in the distribution container 10 that can be monitored, for example, on a sight glass, not shown.
  • the valve 23 can also be acted upon by a level sensor (not shown here in more detail, which is described in more detail in connection with FIG. 4) and thus regulates the functionally correct amount of the preparation agent 11 in the distribution container 10.
  • the pressure source 12 is connected via a branch line 25 to the refill container 20 ′, which in this case is pressure-tight.
  • the lines 25 and 19 can each be provided with a manually operated valve in order to prevent preparation agent from escaping or a pressure drop in the distribution container 10 when the refill container 20 'is replaced.
  • both the preparation agent 11 is conveyed from the refill container 20 ′ into the distribution container 10 and from the distribution container 10 via the lines 9 of the same length to the nozzles 8 by the pressure source 12.
  • the distribution container 10 is connected to a compressed air pump 27, the storage container 20 being designed as an open reflux container 16 '.
  • the preparation medium 11 is conveyed from the reflux container 16 into the distribution container 10 via a preparation medium pump 26.
  • the preparation agent pump 26 pumps the preparation agent 11 out of the storage container 20 into the distribution container 10 and from there, as in the previous exemplary embodiments, to the nozzles 8.
  • FIG. 4 shows the most important components of a control device used for example in the embodiment of FIG. 3 and not shown there.
  • a level sensor 28 is arranged within the distribution container 10 and connected to the preparation agent pump 26 via a control line 32.
  • Preparations can be introduced into the distribution container 10 to the desired extent via a line 33.
  • a pressure sensor 29 is arranged in the distribution container 10, which controls the compressed air pump 27 via a control line 30 and a control or regulating unit (not shown), as a result of which compressed air is introduced into the distribution container 10 via the line 31 to the correct extent.
  • the preparation agent feed pump 26 can be controlled depending on the level.
  • a fill level sensor 28 is provided, which controls a control unit 41 via a line 40, which in turn controls via a line 43 is connected to the preparation agent pump 26.
  • the intended regulation of the pressure moves away when the pressure medium is lost: the volume of the preparation agent 11 and the pressure medium in the distribution container 10 are kept the same - if the pressure medium is lost, the pressure drops.
  • a pressure sensor 29 is provided, which is connected via a line 42 to the control unit 41, which in turn is connected via a line 43 to the preparation agent pump 26.
  • the pressure medium is lost, only the level of the preparation agent increases; however, the pressure that is decisive for the even preparation job is kept the same. The corresponding level would have to be compensated for by occasionally supplying pressure medium through a supply valve, not shown.
  • the distribution container conveys preparation agent to the nozzles through a gas pressure cushion ensures a simple, constructive structure with high effectiveness with sensitive controllable delivery of the preparation agent 11 to the threads 2.
