Definitions

  • cross-wound bobbins (11, 111) in textile machines, in particular cross-wound bobbins (10), the cross-wound bobbins (11, 111) being used in subsequent twisting work processes with simultaneous duplication in machines which are used to work with two essentially axially arranged
  • Cross-wound bobbins (11, 111) are suitable, in this system the two cross-wound bobbins (11, 111) have a predetermined length of meter of the spooled yarn and the length of the meter on one (11) is different in relation to the other spool (111), and wherein the cross winding machine (10) is regulated in such a way that, on the same winding unit (16), cross coils (11) which are suitable for attachment at the top and cross coils (111) which are suitable for attachment at the bottom are produced, and vice versa.
  • the present invention relates to a system for producing cross-wound bobbins with different meter lengths on the same cross-wound bobbin unit
  • the present invention particularly relates to a system for winding two coils with different meter lengths on the same winding unit, the coils being able to be removed together.
  • the invention is applicable to packages of all types of packages, but can be used on any machine which produces packages of a predetermined meter length.
  • winding heads of the machine can be changed at intervals, or that half of the winding units of this cross-winding machine will produce cross-wound bobbins for attachment in the upper position and the other half for attachment in the lower position, such as in IT 60456 B / 79.
  • systems of the known technology have numerous disadvantages.
  • Another disadvantage is the organizational difficulty and the mechanical engineering complication that results from the fact that bobbins of different meter lengths come from different bobbins or from half of the machine and must be presented side by side at the exit of the machine.
  • the system provides for the production of cross-wound bobbins of different lengths on the same winding unit of the cross-wound machine, whereupon the cross-wound bobbins are duplicated in the subsequent twisting process.
  • the winding unit produces, in the desired order, for example first the cross-wound bobbin to be put on in the lower position with a predetermined meter length and then the bobbin to be put on in the upper position, likewise with a predetermined but different length of the previous one.
  • a device known as a length meter or a similar device for the purpose of counting the meter length of the spooled yarn is set in advance to two successive different meter lengths.
  • suitable switching devices set the meter length for the second package and so on.
  • Length meters and switching means can be positioned in each winding unit or, more advantageously, in a central unit in the control group of the machine, where they work together with means relating to the individual winding heads.
  • the first cheese produced is put down and held in the vicinity of the winding station by suitable means which cooperate with the winding station.
  • both bobbins are removed in pairs on known transport means which work together with the cheese winder and are dimensioned so that they can accommodate the bobbins.
  • the two packages with different lengths of meter come in succession to the exit of the package.
  • the packages come to two or more outputs of the package machine.
  • the invention thus concretizes in a system for the production of cross-wound bobbins in textile machines, in particular cross-wound bobbins, wherein the cross-wound bobbins can be used in subsequent twisting operations with simultaneous duplication in machines which are suitable for working with two cross-wound bobbins arranged essentially axially one above the other , and wherein the cross-wound bobbins have a predetermined length of meter of the wound yarn, which is different between the two cross-wound bobbins, the system being characterized in that the cross-wound bobbin winder is set in such a way that the same bobbin alternately produces cross-wound bobbins which are suitable for attachment in the upper one Position and cross-wound bobbins, which are suitable for attachment in the lower position, and vice versa.
  • FIG. 1 shows the rear view of a cheese winding machine 10 which produces cheese 17 and 111 of different lengths.
  • the cross-wound bobbins 11 and 111 arrive in pairs at the exit of the cross-wound bobbin winder 12 using a conveyor belt 13 of known technology.
  • the conveyor belt 13 is provided with driver stops 14 and works together with a sensor 15 for the cross-wound bobbins 11 and 111, which forms a unit with the cross-wound bobbin winder 10 and is suitable for stopping the belt 13 in the presence of the cross-wound bobbins 11 and 111 at the exit of the cross-wound bobbin winder 12 .
  • the winding units 16 each work together with a platform 17 which is suitable for receiving two cross-wound bobbins 11 and 111 in pairs and feeding them to the conveyor belt 13.
  • the platform 17 can lie essentially on the same plane on which the cross-wound bobbins 11 and 111 are produced, as in the embodiment shown in FIGS. 1 and 2.
  • the platform can also be located on other levels in cooperation with suitable removal means for the cross-wound bobbins 11 and 111, this still being within the scope of this invention.
  • the stop element 18 temporarily blocks the roll of the cross-wound bobbin 11 and then the cross-wound bobbins 11 and 111 onto the conveyor belt 13.
  • the bobbin 11 is placed on the platform 17 and held by the stop element 18.
  • the bobbin 111 is then produced with a predetermined length of meter, which is different from the length of the bobbin 11, and this in turn is placed on the platform 17. It is held there by the simultaneous action of the cheese 11 and the stop element 18.
  • the winding unit 16 starts winding yarn onto a new empty tube 19 after having selected the same length of meter as the cross-wound bobbin 11.
  • the stop element 18 works together with suitable means, which senses the spaces between the driver stops 14 on the conveyor belt 13. As soon as an empty space on the conveyor belt 13 moves past a winding unit 16, at which two cross-wound bobbins 11 and 111 are held by the stop element 18, the stop element 18 catches and transfers the cross-wound bobbins 11 and 111 onto the conveyor belt 13.
  • the stop element 18 can cooperate with a second stop 118, which also works on the platform 17 and is suitable for holding the second cross-wound bobbin 111 in place, in order to avoid the contact of the bobbin 111 with the bobbin 11 and to place them one after the other on the conveyor belt 13 facilitate.
  • the cross-wound bobbins 11 and 111 with the different predetermined meter lengths are brought to the outlet 12 in order to be removed there in pairs or manually or to work together with means for positioning the two bobbins over one another.
  • FIG. 2 schematically illustrates, seen from above, the rear part of a cheese winder 10 with the bobbins 11 and 111 being deposited one behind the other.
  • the stops 18 and 118 for holding the cross-wound bobbin 11 and the cross-wound bobbin 111 are located on the platform 17.
  • the stops 18 and 118 work in chronological succession, first to hold the cross-wound bobbins 11 and 111 on the platform 17 and then to release them and allow them to transfer to the conveyor belt 13.
  • the conveyor belt stops opposite the winding unit 16 in order to take up the bobbin 11. The conveyor belt then moves so far forward that the spool 111 can be accommodated between the space of the conveyor belt 13 delimited by the driver stops 14.
