Definitions

  • the invention relates to a device for tension compensation of the threads on a creel according to the preamble of claim 1.
  • the threads drawn off at the creel must, as is known, have a constant thread tension so that a uniform winding is produced.
  • the different running lengths of the threads cause tension differences due to different air and frictional resistances. It is therefore necessary to compensate for these voltage resistances using a suitable device. This is done by different braking of the threads or the thread groups with the same barrel length, the braking force brought into effect being approximately inversely proportional to the difference in the barrel lengths.
  • CH-A-400 029 has disclosed a device for tension compensation between a plurality of threads to be processed simultaneously, in which the braking force of the thread brakes is electrically controllable.
  • An electrical voltage divider which is divided in the ratio of the length differences, serves for the proportionally equal control. The voltage at the voltage divider can be changed with a regulator.
  • a device for operating pneumatically loadable thread brakes in which a different static loading pressure of the thread brakes is derived from the pressure drop of the flowing pressure medium.
  • a main line through which the pressure medium flows is arranged along the creel, to which the thread brakes pass individually or in groups Branch lines are connected.
  • the main line is divided into individual sections of different static pressure by built-in flow resistance elements.
  • the known devices are relatively complicated and therefore prone to failure.
  • an individual change in the braking force of individual thread brakes or groups of thread brakes is not possible.
  • the braking force of the thread brakes can be changed, but only in the same proportion and without individual adjustment.
  • constantly changing operating conditions on the winding system such as decreasing bobbin diameter, increasing winding speed, temperature fluctuations etc. necessitate a proportional readjustment of the thread brakes in order to maintain a constant thread tension on the thread winding despite taking into account the run lengths.
  • the actuating means can be given a relative position which gives the thread brakes a certain static braking force.
  • This relative position can be changed as a function of the running length of the threads assigned to the thread brakes, but at the same time also proportionally equal to all thread brakes. This is facilitated by the individual controllability.
  • each actuating means could be assigned its own drive element.
  • the transmission can also have a control rod on which the actuating means engage at a distance, the control rod being connected to at least two drive elements which can be individually controlled to change their relative position. This makes it possible on the one hand to individually preset the braking force on the thread brakes and, on the other hand, to readjust all thread brakes together in the simplest way.
  • the drive elements allow remote control, so that the mechanically adjustable parts are kept to a minimum.
  • control rod For the non-uniform deflection of the control rod, several drive elements are particularly advantageously connected to it.
  • the control rod can be given a curved or a polygonal relative position, which enables a disproportionate increase or decrease in the braking force relative to the running length of the threads.
  • the control rod can be designed to be flexible, or it can be divided into individual sections which are connected to one another in an articulated manner.
  • one drive element preferably acts on each end of an individual section or on the joints.
  • the influencing of the braking force on the thread brakes via the actuating means depends on the points at which the latter attack on the control rod. Due to the structure of the creel, the actuating means will preferably engage the control rod at regular intervals. However, the drive elements are preferably placed on the control rod such that at least two actuating means act on the control rod between two drive elements. In this way, individual groups of actuating means are formed, which are adjusted approximately proportionally.
  • the control rod can be deflected particularly easily if the drive elements are pressure medium cylinders which are articulatedly connected to the control rod. Instead of the pressure medium cylinders, electrical drive elements would also be conceivable.
  • a particularly simple control of the pressure medium cylinders can be achieved if these are pneumatic cylinders and if an electropneumatic pressure control valve is assigned to each pneumatic cylinder.
  • the actuation of the pneumatic cylinder or the force transmitted with it takes place via a variable control voltage which is proportional to a certain output pressure at the pressure control valve.
  • the signal lines can be accommodated in a space-saving manner without great effort, so that the drive elements can be remotely controlled without complex cable routing.
  • the readjustment of the thread brakes is preferably carried out in that the drive elements can be controlled and proportionally adjusted by a processor, in that a desired thread tension can be programmed in any operating state in order to form a setpoint value, the processor being connected to a tension measuring device as an actual value transmitter to form an actuating signal.
  • the programmed setpoint can always remain the same, or it can change continuously, particularly when the winding process is started or stopped.
  • the tension measuring device is preferably a deflectable measuring roller on which the pulled-off thread assembly is deflected. The one for an excursion
  • the decisive size is the sum of the thread tensions of the thread group. An individual tension measurement on each thread to form the actual value would also be conceivable.
  • a winding system for example a warping or warping system, consists in a manner known per se of a winding machine 2 and a creel 3.
  • the creel 3 releases the coils 4 attached to it the threads 5 are wound as a thread dressing 6 in the winding machine 2 on a warping drum 7.
  • Each thread 5 passes through a thread brake 8 for generating a specific thread tension, as well as a thread monitor 9, in which each thread is monitored for existence.
  • the threads are guided in an orderly manner on the cross reed 10 and brought to the desired distance in the cross reed 11.
  • the thread assembly 6 arranged in this way finally passes over a deflectable measuring roller 12 and a deflection roller 13 on the warping drum 7.
  • the bobbin creel consists of a plurality of vertical bobbin rows 14 and the thread tensioner rows 15 assigned to these rows.
  • the length of the bobbin creel 3, which can be up to 15 m and more, leads to different running lengths of the threads between the first bobbin row 16, which the warping drum 7 is closest, and the last coil row 17, which is furthest from the warping drum 7.
  • the thread tensioners 8 consist, for example, of a plate tensioner with a saucer 18a and with a saucer 18b, the latter being more or less pressed onto the saucer 18a via a pressure element 19 and thereby exerting a braking force on the thread guided between the plates.
  • Each pressure element 19 has a resilient intermediate member e.g. in the form of a compression spring 20, which causes a certain bias.
  • the plate tensioner there would also be other types of thread brakes such as Roller tensioner or the like conceivable.
  • All pressure elements 19 of a thread tensioner row 15 are connected to one another via a push rod 21 and can thus be moved together in the vertical direction. With a downward movement of the push rods 21, the two plates 18a and 18b are obviously pressed against each other more, so that they generate a greater braking force. In contrast, when the push rods 21 move upwards, the compression springs 20 are relieved, so that the thread tension is reduced.
  • the push rods 21 are mounted in guides 22 on the creel frame, not shown.
  • control rod 23 To adjust the push rods 21, these are non-positively connected to a control rod 23 at their lower end.
  • the connection is preferably made by means of joints 25.
  • the control rod 23 is also connected to pneumatic cylinders 24, which are also articulated to the creel frame (not shown) and act on the control rod 23 at the joints 39.
  • pneumatic cylinder 24a and 24e is shown at both ends of the control rod.
  • FIG. 2 shows an alternative embodiment in which the pneumatic cylinders 24a to 24e act on the control rod 23.
  • the control rod 23 itself is divided into individual sections 23a to 23d which are connected to one another in an articulated manner. Depending on the control position of the individual pneumatic cylinders, the control rod 23 can be shifted in a polygonal or straight manner. Between two pneumatic cylinders, two push rods 21 are articulated on a control rod section.
  • a thread 5 must pass through different guide eyelets (not shown) from the bobbin to the thread monitor 9.
  • the air resistance also increases the thread tension when the thread is longer. For this reason, there is an ever increasing increase in between the first coil row 16 and the last coil row 17 Thread tension. Therefore, in order to obtain a constant thread tension of all threads on the measuring roller 12, the thread brakes 8 must be subjected to a braking force which is approximately inversely proportional to the running length of the threads assigned to them. The threads coming from the first bobbin row 16 are thus braked more than the threads coming from the last bobbin row 17.
  • the relationship between the natural thread tension and the action of the braking force is shown in a diagram in FIG.
  • the pneumatic cylinders 24a to 24e are plotted on the abscissa.
  • the braking force P is plotted on the ordinate, the line 37 representing the actual thread tension without the action of the thread brakes.
  • Line 38 shows the approximately inversely proportional increase in braking force on the thread brakes, which results in the constant thread tension, which is shown with line 36.
  • the pneumatic cylinder 24e is extended more than the pneumatic cylinder 24a, so that the thread brakes of the last bobbin row 17 are disproportionately relieved than the thread brakes of the other bobbin rows.
  • This deflection always results in the same permanent nominal thread tension, represented by the straight line 36 in FIG. 5.
  • the line 40 shows the neutral, horizontal position of the control rod 23.
  • the winding machine 2 has, for example, an operating station 26 with an input station 27, in which the disposition data of the thread group 6 to be wound can be entered via input keys 28 and pushbuttons 29. This data is visible in the display field 30 and is simultaneously fed to the processor 31.
  • the input data are textile and mechanical target data such as the thread quality, the number of threads, the desired thread tension, the winding length, the Winding speed or the number of warping belts. Entering the previously mentioned data into the input station 27 initially has the effect that the correction data stored in the processor 31 influence the pneumatic cylinders 24a to 24e in such a way that the control rod 23 receives a deflection which brings about a constant nominal thread tension for all threads.
  • the measuring roller 12 continuously measures the tension of the thread assembly 6 in a manner known per se and passes this data via the connecting line 32 to the processor 31, where these actual data are compared with the stored target data. If a deviation is found, electrical control signals are emitted to the electropneumatic pressure regulating valves 34a to 34e via the output lines 33a to 33e. These convert the electrical control signal into a proportional pressure, which is fed as control pressure via the pneumatic connecting lines 35a to 35e to the pneumatic cylinders 24a to 24e.
  • the mode of operation and function of electropneumatic pressure control valves is described, for example, in the journal “Oelhydraulik und Pneumatik" 31 (1987) No. 5, pp. 454 to 456.
  • the difference in deflection or the static pressurization between the individual pneumatic cylinders 24a to 24e can now be entered, for example in percentages or in absolute values, in order to achieve the aforementioned uniform thread tension. It is of course also possible to take these difference values into account when entering the thread quality within the warping disposition, so that no additional correction values need to be entered.
  • the control mechanism described can not only be used to compensate for the influence of the reducing coil diameter D or the change in speed. It is also possible to have an increasing or in the processor 31 under certain operating conditions To program decreasing thread tension on thread assembly 6. This applies especially to the start-up process of the winding system, in which the change in voltage can be compensated for when the machine starts up.
  • the drive elements 24 would not have to act directly on the control rod 23. It would also be conceivable to connect the drive elements to the control rod 23 via a lever mechanism. Instead of articulated individual sections, the control rod 23 could also be designed so flexibly that a desired non-uniform deflection is possible without the installation of articulations.
