  • the automatic tape winding machine comprises a plurality of driven winding shafts, a winding-on mechanism and a cross cutting unit for cutting tapes.
  • the winding shafts are mounted on pneumatically pivotal I arms in such a way that the packages do not touch one 16 Claims, 2 Drawing Figures 1 AUTOMATIC TAPE WINDING MACHINE
  • This invention relates to an automatic tape winding machine for winding tapes.
  • One known machine of this kind consists of a plurality of driven winding shafts with winding tubes, winding-on mechanisms for winding the tapesonto the tubes, and cross-cutting units for cutting the tapes after the required package diameter has been reached.
  • tapes cut for example by roll cutting machines can be automatically wound up to a certain diameter onto cardboard tubes and then cut.
  • the cut tapes are wound onto two winding shafts arranged horizontally one above the other and fitted with cardboard tubes.
  • the arrangement of these winding shafts is attended by the disadvantage that the time required to set up the shafts is of the same order of magnitude as the time required to cut and wind an approximately 100 m long roll.
  • Another obstacle to automatic operation is that, when wound on, the individual tapes have to be stuck to the cardboard tubes with adhesive strips.
  • the tapes have to be constantly checked during winding on to ensure that their edges are in line.
  • the tapes of the completed packages are cut by hand and the packages individually removed from the winding shaft. This also takes a considerable amount of time.
  • the object of the invention is to construct an automatic tape winding machine by which even sensitive tapes such as photographic papers, can be wound at high speeds.
  • the winding shafts are mounted on pneumatically pivotal arms in such a way that the packages do not touch one another when the winding shafts are swung in or out, and in such a way that when swung in, some of the winding shafts are initially situated in the vicinity of the winding-on units and are then swung out by completed packages, whilst at the same time the rest of the winding shafts are swung out and remain stationary in readiness to receive empty winding tubes after the completed packages have been removed.
  • the winding-on units advantageously consist of a two-piece hollow cylinder which has a threading slot and contact roller openings. When the winding shafts are swung out, one half of the hollow cylinder is opened out so that the winding shafts can be removed from the winding-on unit.
  • the winding-on units are preceded in the direction unit.
  • FIG. 1 diagrammatically illustrates the structure of the machine as a whole.
  • FIG. 2 shows an enlarged detail in the vicinity-of the winding-on unit.
  • a wide web wound into a large roll 1 is cut by means of a conventional roll cutting machine 2 into a plurality of narrow tapes. These tapes are then delivered in two groups, three of the same size to an automatic tape winding machine 4 which is built up on two winding units 5.
  • the winding unit 5 consists of a pivotal tape drive 6, a cross cutting unit 7 (FIG. 2) of a winding-on unit 8, two winding shafts 9a, 10a and 9b, 10b, onto which winding tubes 11 are fitted, and of the drive elements for the winding shafts and of the tape drive (not shown).
  • Pivotal arms 12 are mounted on side plates 13 of the machine at such intervals that, when swung in and out, they do not touch one another, even when packages 14 have reached their full diameter.
  • the winding shafts 9a, 10a, and 9b, 10b are driven by electric motors (not shown) which are mounted on the pivotal arms 12. However, the winding shafts can also be driven centrally from outside through friction drives. In this case, the drive is best coupled with the roll cutting machine 2.
  • the pivotal movement of the arms 12 is controlled in known manner by a pneumatic unit.
  • the winding-on unit 8 ensures that the tapes 3 are wound cleanly onto the winding tubes 11. It consists essentially of a full length hollow cylinder 15 whose length (height) is adapted to the width of the group 3 of tapes and to the length of the winding shafts 9a, 9b and 10a, 10b.
  • a hollow cylinder 15 which is in two parts, one of which can be opened out on hinges 16; is provided and the winding shaft 9, 10 onto which the winding tubes 11 are fitted is accommodated in the hollow cylinder 15.
  • the hollow cylinder also comprises an axially parallel threading slot 17 through which the group 3 of tapes is introduced.
  • contactroller openings 18 are provided along its outer surface. In these openings, small rubber rollers 19 press resiliently on the winding tube 11.
  • the rubber rollers are arranged at close intervals over the entire length of the hollow cylinder so that tapes of any width can be rolled up. In the vicinity of the threading slot 17 there is a roller 20 which ensures that the tapes are cleanly threaded.
  • the group of tapes 3 is pushed in to the hollow cylinder 15 by means of the tape drive 6 and the guide roller 20.
  • the hollow cylinder 15 the hollow cylinder 15
  • tapes are diverted so that they rotate around the rotating winding tubes 11 and are pushed by the rubber rollers 19 between the winding tubes 11 and the ending length of tape. After a few turns the tapes are then wound firmly onto the winding tubes 11, thus completing the winding on phase.
  • the winding-on unit 8 is then opened by means of a pneumatic mechanism 21 so that the winding shafts with the rolls l4 wound onto them can be swung out.
  • a cross cutting unit 7 is arranged in front of the threading slot 17 for cutting the tapes after the prescribed package diameter has been reached. Its most important components are a circular blade 22 and a steel support 23 between which the tapes are guided. The circular blade is mounted on a carriage 24 suspended from a guide rail 25. The carriage is driven during cutting by means of a spindle 26.
  • the tape drive 6 is situated immediately in front of the cross cutting unit 7, consisting essentially of a roller 27 and of a pair of rollers 28, 29 provided with a drive.
  • the tapes are guided through and advanced between the rollers 28, 29.
  • the upper roller 29 is designed to be raised by a pneumatic mechanism 30 when it is desired to switch off the tape feed.
  • the wide web coming from the offwinding station 1 is cut by the roll cutting machine 2 into a plurality of narrow tapes. These tapes are then divided up into the groups 3 which are delivered to the automatic tape winding machine.
  • the groups 3 of tapes are then threaded by the tape drive into the winding-on units 8 in which the winding shafts 9a, 9b are accommodated. After a few turns the tapes are wound firmly onto the winding tubes 11 which complete the winding-on phase.
  • the windingon units 8 are then opened by pneumatically opening one half of the hollow cylinder 15.
  • the winding shafts 9a, 9b are then swung out and the rolls 14 wound to the final diameter.
  • the machine functions semiautomatically. While tapes are being wound on and then wound to completion on the winding shafts 9a, 9b, the winding shafts 10a, 10b are stationary and being unloaded and reloaded. This semi-automatic operation provides for considerable rationalisation.
  • An automatic tape winding machine for winding tapes to a required package diameter, comprising a pair of driven winding shafts with winding tubes, a windingon mechanism for starting the winding of the tapes onto the tubes, a cross cutting unit disposed adjacent the winding-on mechanism for cutting the tapes after the required package diameter has been reached, wherein the winding shafts are mounted on pivotal arms of different lengths so that each of them can be alternatively moved from a respective location remote from the winding-on mechanism to engagement within the winding-on mechanism to have the beginning of a tape wound thereon, and back to the remote location to have the required diameter for a tape package wound thereon or an empty tube mounted thereon, the pivotal arms and winding shafts being adapted so that movement of one of the winding shafts from and to engagement within the winding-on mechanism can be affected without it or a package supported thereon contacting any of the other winding shafts or packages supported on any of the other winding shafts when the other shaft of shafts are located in their respective remote locations.
  • the winding-on unit consists of a two piece hollow cylinder with a threading slot and contactroller openings, one of the two pieces of the hollow cylinder comprising a hemispherical portion, the hemispherical portion being mounted on a hinge for movement opening and closing the hollow cylinder to permit the winding shafts to be swung in and out of the hollow spaces for initiating the winding in the hollow space and removing the winding shaft to complete the winding to the full package diameter outside of the hollow space or an empty tube mounted thereon.
  • An automatic tape winding machine wherein the winding on unit is preceded in the direction of tape travel by a cross cutting machine having a guide surface directing the tape into the windingon unit, and the cross cutting machine being constructed and arranged to cut the tape on the guide surface leaving a new end which can be threaded into the winding-on unit for winding the following tape package.
  • said winding-on mechanism comprises a substantially cylindrical assembly surrounding a hollow space, the assembly including a short arcuate plate, the short arcuate plate having a short concave surface disposed toward the path of movement of the winding shafts toward the winding-on mechanism, a hemincylindrical concave-surfaced plate having a tip end and a base end abutting the short arcuate plate, the hemicylindrical concave-surfaced plate being mounted upon a rotatable arm for movement contiguous to and away from the concave surface whereby the side of the mechanism in the path of movement of the winding shafts is opened for allowing the winding shafts to be moved in and out of the hollow space within the cylindrical assembly, a tape-feeding table having a discharge end disposed adjacent the cylindrical assembly and under the tip end of the hemicylindrical concavesurfaced plate whereby the leading ends of the tapes are directed into the gap between the tip end and the winding tubes
