  • My invention relates to winding device for strand, bandshaped and web material or the like as employed for example to produce coils or beams, hereinafter referred to collectively as wound bodies, wherein these wound bodies are formed both of individual threads or bands or the like as well as of a plurality of simultaneously wound threads or bands or the like.
  • the material wound on all of the winding bodies by of the same length.
  • the same length is sufficient in those cases wherein the rotary speed of the unwinding wound bodies can be varied.
  • the unwinding devices are of the type wherein the wound bodies must unwind at the same rotary speed, for example because all of them must necessarily be driven at the same time, it is desirable not only that the wound length of all the unwinding wound bodies should be the same but also that the diameters of the individual winding bodies should be the same so that in equal intervals of time equal lengths of the material can be unwound from all of the wound bodies.
  • a winding device for strand or web material comprising means for winding the material into a wound body, means for producing a value proportional to the number of rotations of the wound body, means for producing a value proportional to the length of the material being wound, storage means connected with both of the value producing means for storing, in an initial winding operation, the values of the lengths of wound material appertaining to a respective predetermined number of rotations or vice versa, and control means couplable to the storage means for controlling tension of the material or pressure exerted on the windings of the wound body, in a subsequent winding operation.
  • I provide a device for producing a value proportional to the number of rotations which emits a pulse signal for each rotation or partial rotation after a predetermined number of rotations, or which is formed of an information or data carrier such as a magnetic tape for example, which is moved at a speed proportional to the rotary speed of the winding device, and which is coordinated with an information or data transmitter, for example a tape recording head, which produces magnetic markings on the information or data carrier at equal time intervals.
  • an information or data transmitter for example a tape recording head
  • I provide device for producing values proportional to the length of the wound material wherein a cylinder or roller rotated at the speed of the wound material in dependence on a predetermined number of rotations, which can also correspond to a fraction of a rotation, produces a pulse signal alternately
  • the device for producing values proportional to the length of the wound material may be an information or data carrier, such as a magnetic tape, which is moved at a speed proportional to the speed of the wound material, and which is coordinated with an information or data transmitter, such as a tape recording head, which produces magnetic markings on the information or data carrier at equal time intervals.
  • both of the devices for producing values proportional respectively to the number of rotations of the winding device and to the length of the materia] wound on the wound body are connected to a storage device which either stores the values of the lengths of the wound material appertaining to a respective predetermined number of rotations of the wound body or, conversely, the values of the number of rotations of the wound body appertaining to respective predetermined lengths of the wound material. In this way, the actual winding condition of the beam is recorded in the storage device.
  • FIG. I is a diagrammatic elevational view, partly in section, of a composite winding device according to-my invention having two data carriers and both a device for adjusting the tension of the material being wound and a device for applying pressure to the wound body;
  • FIG. 2 is a fragmentary sectional view of FIG. 1 taken along the line Il-Il in the direction of the arrows;
  • FIG. 3 is a fragmentary plan view of the magnetic tapes of FIG. I in a stage wherein the markings thereon are in lateral alignment;
  • FIG. 4 is a view corresponding to that of FIG. 3 but showing a stage wherein the markings on the respective magnetic tapes are out of lateral alignment with one another.
  • a winding device I wherein a thread, band, web or other flexible strand material 2 is wound on a beam 3 to form a wound body 24.
  • the flexible material 2 runs through a tensioning device 4 which is formed biased toward a bearing member 5 and a tensioning runner 6 biased toward the bearing member 5 by a compression spring 7, whichis in engagement at one end thereof with the tensioning runner 6 and abuts at the other end thereof against a compression member 8.
  • a conventional length measuring device of the counter type found in tape recorders, for example, represented in its simplest form by rollers 9, l0 and 11, is disposed between the beam 3 and the tensioning device 4.
  • a device 12 such as a gear train or chain transmission for example, serving to produce values that are proportional to the number of rotations of the wound body 24 is coupled to the beam 3.
  • a device 13 serving to produce values which are proportional to the lengths of the wound-up flexible material 2, such as another gear train or chain transmission for example, is coupled to the length-measuring device 9, l0 and 11. Both devices 12 and 13 are connected to rotary drive wheels of a storage device 14 formed of endless magnetic tapes l5 and 16, serving as information or data carriers, and magnetic recording heads 17 and 18 serving as information or data transmitters.
  • the magnetic recording heads 17 and I8 produce magnetic markings 23 at predetermined time intervals on the magnetic tapes I5 and 16, and in fact fully independently of the speed of the strand or web 2.
  • the recording heads l7 and 18 are connected through switches 25 and 26 with conventional pulse signal generators 40. The spacings of the markings on the magnetic tapes 15 and 16 are then a measure of the number or rotations of the wound. body 24 and of the speed of the strand or web material 2, respectively.
  • the magnetic tapes 15 and 16 respectively are returned to their starting position at the beginning of the winding operation. Thereafter, the recording heads 17 and 18 are switched over by the switches 25 and 26 to receive pulse signals so that they act as information receivers and can pick up the markings on the bands 15 and 16 as pulse signals. These pulse signals are conducted through ampliflers 27 and 28 to step motors 29 and 30 which drive a gear pair 20a and 20b of a differential gear system 20 forming a control device. If, as shown in FIG. 3, no difference or spacing exists between the markings 23 on the magnetic tapes l5 and 16 during the winding operation i.e.
  • both step motors 29 and 30 drive the gears aand 20b of the differential transmission 20 simultaneously in opposite rotary directions so that the pinion 20c and the shaft 31 connected therewith do not rotate. If, as shown in FIG. 4, there is a difference or spacing 32 between the markings 23 however, i.e. the markings 23 of the respective magnetic tapes l5 and 16 are not in lateral alignment because for example, due to reduction of the initial tension of the winding material 2, too large a diameter of the winding occurs and accordingly, for a specific number of rotations, the wound-up length of strand or web material 2 is greater than that of the first wound body, the step motor 30 in this case runs faster than the step motor 29.
  • the pinion 200 is thereby set into rotation so that the shaft 31 rotates in the direction of the arrow 34 as shown in FIG. 2.
  • a lever 21 is connected to the shaft 31 and, through a rod 22 serving as an adjusting member, intensifies the force in the strand or web tensioning device 4 until the markings on both tapes l5 and 16 are synchronized i.e. are brought into lateral alignment as shown in FIG. 3, and therewith conformity of the length of the strand or'web material 2 with the number of rotations of the wound body 24 takes place.
  • the step motor 29 rotates faster than the step motor 30 so that the force in the tensioning device 4 is reduced.
  • the shaft 31 can be connected with a winding pressure device 41 which acts directly on the winding 24 and controls the winding diameter in a conventional manner in accordance with the intensity of the pressure that is exerted. It is also possible to connect a single shaft 31 both with the tensioning device 4 as well as with the winding pressure device 41 through, for example, a single-adjusting member 22.
