Definitions

  • the invention relates to a method for controlling the thread tension on a warping system according to the preamble of claim 1.
  • the invention also relates to a device for carrying out this method according to the preamble of claim 2.
  • the control of the thread tension in different operating states serves, on the one hand, during the warping process To ensure a uniform winding density, but also to prevent loose thread loops from forming even when the machine is at a standstill.
  • a known thread tensioning device in a warping device is e.g. disclosed in DE-A-37 06 872. The behavior during a machine standstill is not addressed in this document.
  • the clamping force for the desired standstill is particularly advantageously adjustable on an adjusting device on the control device. In this way, the desired thread tension can be set even during standstill.
  • the clamping force control signal for the desired standstill can be switched off on the control device or can be set to a value which corresponds to that of the unwanted standstill.
  • the clamping force for both operating modes on the control device can preferably be set proportionally by a single adjusting device. With threads made of different materials and thus with different friction coefficients, approximately similar ratios of the clamping forces are always maintained.
  • FIG. 1 shows a warping system known per se, consisting of a creel 1 and a warping machine 25.
  • a large number of coils 2 are arranged in vertical and horizontal rows.
  • the threads 12 are drawn off from these bobbins and fed to the warping machine 25.
  • a thread brake 3 and a thread monitor 4 are assigned to each bobbin or thread.
  • the thread brakes are arranged on a brake plate 18, wherein in each case a vertical row of thread brakes can be actuated together via an adjusting rod 19.
  • plate brakes are shown in which the thread is pulled through two plates lying one on top of the other.
  • the clamping force is determined by a compression spring, which can be more or less compressed using the adjusting rod 19.
  • All actuating rods of a brake plate 18 are actuated via an actuating motor 22, which can rotate a shaft 21.
  • the actuating rods 19 are connected to the shaft 21 via eccentrics 20, so that rotation of the shaft 21 brings about a common lifting movement of all the actuating rods.
  • the thread monitors 4 monitor the presence of a thread or the presence of a selectable thread tension. If a thread breaks or the thread tension drops below the limit value for other reasons, the thread monitors immediately switch off the warping machine 25.
  • the thread monitors thus function as an emergency switching device, although other emergency switching devices may also be present on the warping system. For example, every system has an emergency switch 23 provided that can be operated by the operating personnel. However, safety devices for protecting the operating personnel, such as light barriers or the like, could also serve as an emergency switching device.
  • the threads 12 are guided through a cross reed 5 to a warping blade 6, where the thread array is arranged into a warping belt 7.
  • the warping belt 7 is wound onto the warping drum 9 as a winding 8.
  • the warping belt Before striking the winding 8, the warping belt is guided around a measuring roller 10 and around a deflection roller 11.
  • the measuring roller is movably mounted and connected to a displacement sensor 13. With the help of the measuring roller 10, the effective warping band tension is measured immediately before the warping band 7 emerges and fed to a processor 14 as the actual value.
  • the processor 14 performs various tasks. With the help of an input station 16, different company-specific data can be stored in the processor 14. This also includes a specific setpoint for the warp tension, i.e. for the thread tension during operation. This setpoint value is continuously compared with the actual value from the measuring roller 10, the servomotor 22 being actuated to load or unload the thread brake 3 when a deviation is determined via the control device 15.
  • the control device 15 is also still in operative connection with the thread monitors 4 and with other emergency switching devices, such as e.g. with the emergency switch 23. If a thread 12a breaks, for example, the control device 15 immediately triggers the warping machine 25 to come to a standstill. At the same time, the servomotor 22 is actuated in order to load the thread brakes somewhat, so that the operating thread tension changes to a standstill thread tension.
  • Desired machine downtimes are also triggered on the control device 15, for example after a certain length of the warping belt 7, which may also be determined via the measuring roller 10.
  • the servomotor 22 is also actuated, but the thread brakes 3 are relieved.
  • the desired thread tension during the desired standstill can be set continuously on the setting device 24.
  • this special function can also be switched off completely, so that the standstill thread tension is the same when the standstill is wanted as when the standstill is not wanted.
  • the entered data and / or the respectively current operating data can be read off on the screen 17.
  • FIG. 2 shows a typical phase of a warping process with an unwanted machine standstill triggered by thread breakage and with a desired standstill triggered by the processor.
  • the warping speed V is plotted in the diagram.
  • the warping machine starts at 26 and accelerates when starting up 27 until the operating speed is reached at 28. Production 29 then takes place until an unwanted stoppage is brought about by a thread monitor 4 at 30. The machine comes to a standstill at 32 via the relatively steep deceleration section 31. The repair takes place in time 33, that is, the torn thread is tied again. At 34, the machine is restarted until it in turn reaches the target speed for further production 37 via the acceleration path 35 at 36.
  • a deliberate standstill is triggered by the processor.
  • the machine decelerates again over distance 39 and at 40 comes to a complete standstill.
  • the downtime 41 a job is carried out in which the entire thread field generally has to be retightened, for example, the new attachment of the warping belt.
  • this Fall at 42 cannot immediately be ramped up to operating speed. Rather, it is only accelerated to a creep speed, which is reached at 44.
  • the machine runs in the crawl gear so that it can be determined whether the work carried out has been successfully completed. Only then can acceleration again take place at 46 in order to achieve the normal operating speed for production at 47.
  • the time / speed diagram shown in FIG. 2 subsequently serves to represent the thread tension and the clamping force on a device according to the prior art in FIGS. 3 and 4 and on a device according to the invention in FIGS. 5 and 6.
  • the thread tension F is plotted in cN, for example, in the same time period.
  • the thread tension reaches the desired operating thread tension 49.
  • a standstill thread tension 50 is set which is somewhat lower than the operating thread tension. Without increasing the clamping force on the thread brakes, the standstill thread tension would decrease further.
  • the operating thread tension is again reached with a slight overshoot, until the standstill thread tension 50 is reached again even when the standstill is desired, but this is the same as when the standstill is undesired.
  • the operating thread tension must then also be reached in the crawl gear, since correct tape application must be ensured even when the machine is running slowly.
