Definitions

  • the invention relates to a method according to the preamble of independent claims 1, 2 and 3. This is intended in the manufacture of identical warp or slip trees in weaving preparation can be achieved that all warp beams, which for the Formation of the warp are handled by the same axis, are of the same quality, that is, the same winding density exhibit. This requirement must apply to both warping and to be fulfilled when writing.
  • DE A 3604790 relates to a method for regulating the thread application on partial warp beams in direct trees. It will be during direct treeing in a given scanning rhythm of the actual diameter of the partial warp beam measured and with a predetermined Target diameter compared. In case of deviations, the winding density influenced by a pressure roller. The respective diameter of the partial warp beam is determined using a tracer roller, which lies on the wrap. But there is no guarantee that the winding length for a certain number of tree turns is always the same. In addition, the tree hardness due to the variable Contact pressure can not be set arbitrarily.
  • DE 3913381 relates to a method for winding a group of threads on a warp beam in which the number of revolutions and the Tree diameter also repeatedly determined and with a Setpoint is compared. Differences are made through control equalized the feed rate of the thread sheet via a driven deflection roller in front of the warp beam.
  • the determination of the tree diameter takes place via a trackable laser sensor and a mechanical displacement sensor. This method is complex and also does not guarantee a related to the speed of the tree always constant winding length.
  • the method according to the invention is for direct treeing or slip characterized by the features in claim 3.
  • the length measurement is carried out exclusively using suitable measuring equipment on the warp beam.
  • the principle of assigning a winding length a certain tree speed is the same as for archipelago.

  • a measurement using a measuring roller is also conceivable is partly wrapped in the thread coulter or else via a pressure roller, which is pressed against the thread winding becomes.
  • the actual value of the warp tension is particularly advantageous when winding of the template tree and when winding the copy tree continuously measured and by comparison with a target value within a Bandwidth kept constant. This allows you to switch between template trees and copying tree already achieved largely the same winding data so that with length-related deviations per tree revolution minimal intervention is required. With that excessive tension differences within the winding avoided, which later in the tissue for quality reduction z. B. for Banding could result.
  • the range of allowed Warp draw deviations are preferably within a value of plus or minus 10% of a setpoint. exceeds or falls below the thread tension, for example the predetermined bandwidth, can be a warning signal and / or Machine stop are triggered.
  • the length adjustment or the regulation of the warp tension during winding of the copying beam can be delayed during warping by delaying the warping drum relative to the copy tree. This can be done particularly well simply by braking using hydraulic disc brakes to reach. Alternatively, the warping drum could be delayed but also by motorized braking via a warping drum drive (4-quadrant drive) possible.
  • the warping assumes that the winding structure of the individual sections on the warping drum at the master beam is the same as the copy tree.
  • this requires regulation the warp tension, at which the actual thread tension of the warping belt measured on a measuring roller in front of the warping drum and compared with a target value, with deviations the thread brakes on the creel are acted upon in this way by the setpoint that the actual value approaches the setpoint.
  • a controlled leveling roller for a reproducible Contribute to the winding diameter. Such a leveling roller is pressed against each warp in the direction of the warping drum.
  • Conceivable is also the storage of data from different template trees, which, for example, under different operating conditions such as e.g. Temperature, humidity, etc. This Data can then be stored in the computer under the same or similar Operating conditions for winding the copier trees become.
  • This Data can then be stored in the computer under the same or similar Operating conditions for winding the copier trees become.
  • the warp tension can also be via a roller unit, which between the machine and the gate is influenced by varying the speed of the rollers.
  • the invention also relates to a device for carrying out the Method, which is characterized by the features in claim 16 is.
  • a creel 1 with the warping machine 5 a thread set 27 drawn off and as a warping belt 7 wound on a warping drum 6.
  • the warp is wrapped around a deflecting roller 10, which has the function of a Measuring roller takes over and which continuously the actual value of the strip tension determined.
  • the actual value is compared in a comparing device 4 compared to the target value and in the event of deviations, a Actuator 3 on the thread brakes 2 changed the braking force.
  • Leveling roller 9 is arranged, which according to FIG. 2 is the warping belt 7 presses against the winding, so that the warp band sections are as uniform as possible 8 can be built.
  • the warping drum 6 the warping drum 6 in the direction of arrow a wrapped on the warp beam 28.
  • the chain becomes optional via a beading roller (deflection roller) for an even thread field and passed over a coating roller 14 on which, for example a wax is applied.
  • the warp in the trees is determined via a measuring roller 15.
  • Both the warping drum 6, and the warp beam 28 are each with a speed sensor 13 or 16 provided.
  • the warping drum drive 11 can for example be a 4-quadrant drive, through which a fine regulation of the Unwinding length or warp tension (winding tension) is possible.
  • the warping drum can also be hydraulic Have disc brakes 12.
  • the saved winding length of the warp winding does not exceed the warping data measured beforehand can be determined on the warp beam 28 optionally a laser sensor 21 for the contactless measurement of the Be arranged winding diameter structure. From the known initial scope of the warp beam and the number of revolutions the coiled warp length also contributes in this way every revolution.
  • a laser sensor 21 ′ can be attached to the warping drum 6 in this way be arranged that when unwinding the winding from the warping drum the winding diameter decrease per warp drum revolution calculated and the corresponding developed warp length determined can be. This warp length per warp drum revolution can then turn the corresponding number of tree turns be assigned.
  • the winding diameter can also be of a radius observer using an algorithm as follows The following can be calculated: Winding data of the warping process and the initial diameter of the The diameter of the winding diameter per tree revolution is calculated and so the tree diameter can be determined. Leaves it then calculate the current winding length per tree revolution.
  • the diagram according to FIG. 4 shows how it is produced the template tree and the copy tree every turn of the Kettbaums 28 a certain number of drum revolutions of the warping drum and thus indirectly assigned a certain developed length is.
  • the drum revolutions are on the abscissa 19 (and thus the winding length) and on the ordinate 20 the Warp revolutions shown.
  • Curve 17 defines a data table for the template tree or for the copy tree.
  • a template tree is wound on the warping drum and via the belt tension control with an approximately constant warp belt tension.
  • the warping drum revolutions and the associated winding length are recorded and as warping data filed in a table.
  • the trees are then planted of the reference tree, the turn of the tree again being recorded and the associated winding length, which results from the warping drum revolutions results to be assigned.
  • This data will now stored as tree data of the template tree in a data table ( Figure 4, curve 17).
  • the procedure is initially the same as for production of the template tree.
  • the determined data table is however constantly compared with the stored data table of the template tree.
  • the The diameter of the copy tree should be larger than that of the template tree.
  • the thread tension in trees must therefore be increased so that the winding diameter of the copy tree is that of the template tree equalizes.
  • the determined winding length is smaller for the copy tree This also results in a smaller diameter than with the template tree in the copy tree, so that the thread tension in the tree must be reduced so that the winding diameter in the copy tree enlarges and adapts to that of the reference tree.
  • the warp beam move is changed via an intervention on the warping drum drive 11 and / or on the disc brake 12th
  • the wound warp length can also be measured in trees using the laser sensor 21, which measures the tree diameter, can be determined.
  • the laser sensor on the warp beam as a control for the length determined during the warping use.
  • a laser sensor can be operated on the same principle 21 'should be arranged on the drum so that when unwinding the winding diameter from the warping drum calculated per warp drum revolution and from this the developed Warp length can be determined. That way ensure that the unwound length of the The warping drum actually has the length wound on the warp beam equivalent.
  • the treatment of the warp threads e.g. to the Coating rolls 14 could have a continuous shrinkage or expansion take place, which is only with a length measurement over the warping drum could lead to errors, usually at same treatments length errors can be excluded can.
  • Belt tension regulation is a prerequisite for warping the winding structure on the warping drum already at the cross beam and matches the copy tree.
  • the tape tension regulation is advantageously carried out by measuring the total tension of the belt shortly before winding up and is averaged with the Target value compared per thread. It is based on the assumption that a change in thread tension on the individual Thread brakes have a proportional effect on the belt tension.
  • Direct treeing or slip is shown schematically in FIG. 5.
