Definitions

  • the invention relates to a warping machine with a warping drum, a yarn sheet guide and a leveling roller, which is connected to a pressing device.
  • the invention relates to a method for producing a chain, in which a group of threads is wound on the circumference of a warping drum and pressed during winding through a leveling roller.
  • the ribbon is offset by its width and the winding process starts again. This process is repeated until the desired width of the chain has been created.
  • a warping drum with a cone at one end is often used.
  • the ribbon being wound is moved up the cone. This results in a correspondingly inclined conical surface on the side facing away from the cone of the coil.
  • the forming roll is pressed with the aid of the leveling roller.
  • the leveling roller is acted upon by the pressing device with a force in the direction of the circumference of the warping drum.
  • the diameter of the forming coil increases with each revolution of the warping drum.
  • the forming coil touches the leveling roller and moves it away from the warping roller against the force of the pressing device.
  • irregularities in the surface of the forming coil are compensated and the winding is compressed.
  • a measuring device which determines the diameter of the winding at the first ribbon, which is also called "master ribbon", at at least two different points of the winding process. From the collected measured values, the feed of the following bands is controlled by the yarn sheet guide.
  • the invention has for its object to make a warping machine cost.
  • This object is achieved in a warping machine of the type mentioned above in that a position sensor is provided which determines a position of the leveling roller relative to the warping drum.
  • the first function is the conventional function of pressing the forming coil.
  • the second function is now the determination of the diameter of the forming coil, so that a separate measuring device for the diameter of the coil can be omitted. This eliminates a previously used sensor unit and the associated costs can be saved. The determination of the diameter of the roll can rather be integrated into the pressing process.
  • the pressing device has a drive and the position sensor is integrated in the drive.
  • the position sensor can be accommodated protected in the drive, so that the risk of damage to the position sensor or damage from environmental influences can be kept small.
  • the drive has a unit with piston and cylinder and the position sensor determines a position of the piston relative to the cylinder.
  • a unit with piston and cylinder which can also be referred to as “piston-cylinder unit" can produce the desired contact pressure with relatively simple means.
  • the determination of the position of the piston relative to the cylinder can also be accomplished relatively easily.
  • the cylinder performs a linear movement relative to the piston, so that one basically only has to determine different positions in one direction of movement.
  • the cylinder has a compressed gas connection.
  • the piston-cylinder unit is thus a pneumatic unit in which the contact pressure of the leveling roller is generated by a pressure in a gas, for example an air pressure.
  • the position sensor is connected to a control device.
  • the controller then receives the information from the position sensor and can use this information for subsequently to be wrapped ribbon to control the winding structure.
  • control device has a memory device with at least two memory locations and stores the position of the leveling roller at two different points of a winding process.
  • the diameter of the roll can be measured at two different points in the winding process of the first ribbon.
  • This measuring principle can also be called “two-point measurement”.
  • the control device can then obtain the necessary information via the leveling roller in order to control the winding structure for the following ribbons. This control is essentially done by controlling the yarn sheet guide.
  • the leveling roller is arranged together with the yarn sheet guide on a shear table, wherein the shear table and the warping drum are parallel to the axis of the warping drum displaced relative to each other. This results in a direct association between the yarn sheet guide and the leveling roller, so that the supplied yarn sheet and the resulting winding can always be acted upon by the leveling roller uniform.
  • the leveling roller is rotatably mounted.
  • the leveling roller is driven by the forming winding. This spares the group of threads.
  • the object is achieved in a method of the type mentioned above by determining a winding diameter of the yarn sheet on the warping drum using the leveling roller.
  • the diameter can be determined and a rule derived from the values determined in which the following ribbons are wound in the same way as the master ribbon.
  • An additional sensor so an additional sensor, but is not required, so that the cost can be kept small.
  • the leveling roller is loaded by means of a drive in the direction of the warping drum and determines the position of the leveling roller in the drive. So you used elements of the drive to determine the position of the leveling roller. Since the warping drum has a fixed and invariable diameter and the leveling roller also has a fixed diameter, it is usually sufficient if one knows the position of the leveling roller or its axis relative to the circumference or the axis of the warping drum.
  • the position of the leveling roller is stored at at least two different points in the winding process. This allows the two-point measurement described above to be carried out and from these two determined measuring points to control the advance of the yarn sheet guide for subsequent strips.
  • Fig. 1 shows in highly schematic form a warping machine 1 with a warping drum 2, a yarn sheet guide 3, for example, a reed, and a leveling roller 4, which is connected to a pressing device 5.
  • the leveling roller 4 with its pressing device 5 is arranged on a shear table 6.
  • the Schrtisch also carries the yarn sheet guide 3.
  • the Schwarzrwolves 6 and the warping drum 2 are relatively parallel to the axis of the warping drum 2, not shown, displaced.
  • a group of threads 7 is withdrawn from a gate not shown in the direction of an arrow 8 and wound on the circumference 9 of the warping drum 2.
  • the warping drum 2 for example, a rotary drive, which sets the warping drum 2 in rotation.
  • the yarn sheet 7 is guided by a roller assembly 10 with two rollers 11, 12, which may also be referred to as a "duo-roll".
  • the pressing device has a drive, which has a cylinder 13 and a piston 14.
  • the cylinder 13 is provided with a compressed gas port 15, via which the cylinder 13, for example, compressed air can be supplied.
  • a position sensor 16 On the cylinder 13, a position sensor 16 is provided, which determines the position of the piston 14 relative to the cylinder 13.
  • the position sensor 16 is connected to a control device 17 in connection, which in turn is in communication with a feed drive 18 for the shear table 6.
  • the warping drum 2 has at one axial end on a cone, not shown, which is inclined relative to the axis of the warping drum 2, for example by 15 °.
  • the ribbon is guided up the cone by means of the yarn sheet guide 3 during winding.
  • the shear table 6 is moved relative to the warping drum 2 (or vice versa).
  • the procedure is such that the diameter of the forming winding is determined during winding of the first ribbon, the so-called "master ribbon".
  • this diameter In the simplest case, one determines this diameter at two points, namely at the beginning of the winding, as in Fig. 1 is shown, and at the end of the winding, as in Fig. 2 is shown. From these two diameter values can be Then calculate the desired course of the increase in the diameter of the coil at each revolution and accordingly control the movement of the shear table 6 relative to the warping drum 2.
  • the memory device 17 has, in a manner not shown on a memory in which the position of the leveling roller 4 can be stored at two different points of a winding operation, for example, the position in Fig. 1 has been shown, so at the beginning of a winding process, and the position Fig. 2 So at the end of the winding process.
  • the leveling roller 4 When winding the leveling roller 4 is pressed against the forming coil 19.
  • the leveling roller 4 is acted upon by means of the piston-cylinder unit 13, 14 in the direction of the circumference 9 of the warping drum 2 with a contact pressure.
  • the leveling roller 4 at the beginning of the winding process for example, a distance of 0.3 mm from the circumference 9 of the warping drum 2 have.
  • the diameter of the coil 19 increases with each revolution of the warping drum 2.
  • the winding 19 contacts the leveling roller 4.
  • the leveling roller 4 is rotatably mounted and is driven by the winding upon contact. By the pneumatic contact pressure of the winding 19 is pressed by the leveling roller 4.
  • surface irregularities are compensated and the coil 19 is compressed.
  • the pressing device 5 at the same time provides information about the diameter of the forming roll 19 and supplies it to the control device 17, it is possible to carry out the control of the winding process in the second and subsequent strips with relatively simple measures.
  • the information from the first wound ribbon is available, which has also been provided by the position sensor 16.
