Definitions

  • This invention relates to a command and control apparatus for a spinning machine for the production of chenille yarn.
  • These machines comprise automatic systems equipped with one or more feeding units on which are positioned a plurality of reels from which the threads for the production of chenille yarn are unwound.
  • each unit for forming chenille yarn comprises a gauge on which is wound one or more threads, called fancy threads, an underlying blade (tangential or circular) for cutting the fancy thread into small pieces and a device for pulling the binding threads.
  • the pulling device comprises a pair of wheels and counter-wheels configured to guarantee the feeding of the binding wires (also called supporting wires) which hold the pieces of fancy thread for the subsequent twisting and winding on the collection spindle.
  • binding wires also called supporting wires
  • the twisting is generated by the rotation of the collection spindle and is necessary both to form the final yarn and to retain the pieces of fancy thread.
  • the constant and uniform distribution of the fancy thread in the chenille yarn are fundamental parameters for the quality of the product.
  • the friction due to the constant passage of the threads on the sliding guides defined by the gauge causes a gradual wear of the gauge which causes a consequent variation in the characteristics of the final yarn.
  • These adjustments include, for example, the replacement and cleaning of the devices of the production machine.
  • these adjustments may include a modification of the parameters relative to the feeding speed of the fancy thread and/or the binding wires to the device which carries out the binding of the above-mentioned threads.
  • the most recently designed spinning machines for the production of chenille yarn may comprise optical sensors designed to inspect the yarn to determine the presence of zones with a low concentration of fancy thread or zones with an excessive concentration of fancy yarn.
  • these sensors assess the volume of the yarn (the quantity of light which the yarn lets pass) and recognise the average concentration of the fancy thread in such a way as to indicate the presence of zones of the yarn with low concentration or high concentration, so that an operator acts on the machine to correct these imperfections.
  • the above-mentioned sensors are not able to assess the effectiveness of the positioning the fancy threads relative to the binding threads.
  • the technical purpose of the invention is therefore to provide a command and control apparatus for a spinning machine for the production of chenille yarn which is able to overcome the drawbacks of the prior art.
  • the aim of this invention is therefore to provide a command and control apparatus for a spinning machine for the production of chenille yarn which allows the quality of the chenille yarn and the accuracy in the process for the production of the yarn to be increased.
  • the numeral 1 generically denotes a command and control apparatus for a spinning machine for the production of chenille yarn, hereinafter indicated for simplicity of description as apparatus 1.
  • the apparatus 1 comprises feed means 2 configured for feeding a plurality of threads to a spinning machine for the production of chenille yarn.
  • the feeding means 2 comprise at least a first roller 3 and a second roller 4 for feeding, respectively, at least a fancy thread and a pair of binding threads to the spinning machine for the production of chenille yarn.
  • the feed rollers are made of metal and/or have a diameter of between 30 mm and 75 mm.
  • each roller rotate about a respective axis of rotation causing a movement of the thread towards the machine for making the chenille.
  • each roller may comprise at least one retaining element, preferably a presser roller 5, operatively associated with a respective counter-rotating roller of the machine for producing chenille yarn, configured to promote the above-mentioned movement of the thread.
  • the thread can be fed to the machine for producing chenille thanks to the pulling action generated by a presser roller 5 and by a respective counter-rotating roller.
  • the apparatus 1 allows the feeding of the thread to the machine for the production of chenille to be adjusted according to the specifications of the production process.
  • the apparatus 1 is configured as a double-line apparatus and the second roller 4 is configured for feeding at least two pairs of binding threads to the spinning machine for the production of chenille yarn in such a way as to obtain two chenille yarns.
  • the second roller 4 may have two presser rollers 5 each of which configured to promote the movement of a pair of binding threads to the machine for the production of chenille.
  • the feeding means 2 comprise a third feeding roller (not illustrated in the accompanying drawing).
  • the second and third feeding rollers are configured for feeding a respective pair of binding threads to the spinning machine for the production of chenille yarn in such a way as to obtain two chenille yarns.
  • the apparatus 1 may comprise a different number of feeding rollers without altering the inventive concept which forms the basis of the invention.
  • each roller may be associated with a respective electric drive 6.
  • the apparatus 1 allows an accurate adjustment of the feeding of the threads to the spinning machine for the production of chenille yarn.
  • the apparatus 1 comprises at least one electric drive 6 configured to move the above-mentioned feeding rollers.
  • the system 1 comprises command and control means 7 configured for detecting at least one property of at least one chenille yarn at the outfeed from the spinning machine for the production of chenille yarn.
  • the command and control means 7 are also designed to modify by feedback at least one operating parameter of the feeding means 2 as a function of the above-mentioned property detected.
  • the command and control means 7 assess the properties of the chenille yarn obtained by the binding between the binding threads and the fancy thread, and can modify, correct and/or determine the operating parameters of the feeding means 2 in such a way as to obtain a chenille yarn with predetermined characteristics.
  • command and control means 7 are configured for detecting at least one property of each of the chenille yarns at the outfeed from the machine and for modifying and/or correcting by feedback at least one operating parameter of the respective roller as a function of the property detected.
  • the command and control means 7 are configured for comparing the property detected with a value or a range of reference values and for implementing a correction of at least one operating parameter of the feeding means 2 when the property detected is different from the reference value or outside the range of reference values.
  • the command and control means 7 are configured for adjusting the speed of rotation of at least one of the rollers.
  • At least one of the above-mentioned operating parameters may be the speed of rotation of at least one of the rollers.
  • the command and control means 7 may be active on each drive 6 for setting a value of the speed of rotation of the respective roller.
  • each drive can be controlled independently.
  • the command and control means 7 may be configured to detect a plurality of properties of the chenille yarn.
  • the command and control means 7 can measure the concentration of the fancy thread in the chenille yarn and/or determine the mutual positioning of the threads making up the yarn.
  • the command and control means 7 may be configured for measuring a dimension of a fancy thread of the chenille yarn at the outfeed from the machine.
  • the above-mentioned property detected by the command and control means 7 may be a value of the diameter of at least a portion of a fancy thread of the chenille yarn.
  • the apparatus 1 allows an accurate control of the properties of the yarn.
  • the command and control means 7 comprise at least one detection unit 8 selected between: optical sensors, preferably a photocell, and/or infrared sensors, and/or acoustic sensors, and/or electromagnetic sensors.
