Definitions

  • the present invention relates to an open-end-type spinning apparatus and the method for unloading a package from an open-end-type spinning apparatus.
  • the current and universally adopted technique involves setting a predefined length (generally selectable by PC), possibly also differentiated in different sectors of the apparatus (faces or sections) and possibly also for the single head.
  • a predefined length generally selectable by PC
  • the spinning process is interrupted by stopping the belt feed to the card, and hence the package is lifted so as not to be pulled in rotation by the cylinder, and an intervention request signal is sent to the spinner's patrol trolley.
  • the trolley positioned on the head that requires the intervention, opens the package holder arm, unloads the package onto a special package unloading belt, arranged adjacent to the head, and positions on the arm an empty tube on which the yarn produced by the spinner will be wrapped.
  • the doffing procedure may not start if the package unloading belt is full: this is because the package that should be doffed could hit another previously unloaded package that is already on the belt.
  • Doffing cannot be achieved even if the unloading belt is in motion: in effect, the newly doffed package arrives rolling in an orthogonal direction with respect to the direction in which the belt runs. This sudden change of direction could overturn the package, causing problems for the correct transport of the packages; moreover, the position that the package being unloaded should occupy could be occupied by a package in transit.
  • the open-end-type spinning apparatus 4 comprises a plurality of open-end-type spinning heads 8 each comprising an open-end spinning unit 12 and a package winding unit 16, wherein each package winding unit 16 winds on a tube 20 a package 24 of yarn obtained from an underlying spinning unit 12.
  • the spinning unit 12 produces yarn which is then wound by a corresponding winding unit 16 on a tube 20 to form a package 24 having a predetermined yarn length.
  • the open-end-type spinning apparatus 4 comprises a first series 28 of open-end spinning heads 8, each provided with a forming position 32 for holding a forming package 24', and an unloading position 36 of a formed package 24" , separated from the forming position 32.
  • the unloading position 36 is a position adjacent to the forming position 32 at which the formed package 24" is substantially removed or ejected from the spinning head 8, i.e. it leaves the spinning head 8.
  • Forming package 24' means a package which has not yet reached the predetermined length and which continues to wind yarn produced by the respective spinning unit 12.
  • Formmed package 24" means a package which has reached the predetermined length and which may therefore be unloaded from the respective spinning head 8.
  • doffing The passage or displacement of the package 24 from the forming position 32 to the unloading position for its replacement with a new empty tube 20 on which to wrap a new yarn is called doffing.
  • the open-end-type spinning apparatus 4 further comprises a second series 40 of open-end spinning heads 8, each provided with a forming position 32 for the holding of a forming package 24', and an unloading position 36 of said formed package 24" , separate from the forming position.
  • a package unloading belt 44 is provided extending along a longitudinal direction X-X, in a position adjacent to the unloading positions 36 of the formed packages 24".
  • the first and second series 28,40 of spinning heads 8 are arranged in rows or faces parallel to each other, along the longitudinal direction X-X, and are spaced from each other by means of said package unloading belt 44.
  • said package unloading belt 44 has a width L substantially less than a diameter D of said formed packages 24" and slides to the inside of a transit channel of the formed packages 24" , having a slightly greater width than the diameter D of said formed packages 24".
  • open-end spinning heads 8 of the first and second series 28,40 are provided with an intermediate holding position 48, between each forming position 32 and each unloading position 36, and respective retention means 52 to selectively block, in said intermediate holding position 48, the formed package 24" , regulating the passage thereof to the subsequent unloading position 36.
  • the retention means 52 once activated, are able to block the formed package 24" in the intermediate holding position 48, and once deactivated allow the passage of the package 24" from the intermediate holding position 48 to the unloading position 36.
  • the retaining means 52 comprise a bar 56 configured to move from a retracted position, wherein it does not interfere with the formed package 24", to an extracted position, wherein it blocks the formed package 24" in said intermediate holding position 48.
  • the bar 56 is operatively connected to an actuating cam 60.
  • said retention means 52 may comprise rocker or lever systems.
  • a single bar 56 is operatively associated with each series 28,40 of spinning heads for the simultaneous retention of the formed packages 24" in the respective intermediate holding positions 48.
  • the open-end-type spinning apparatus 4 comprises a plurality of retention means 52, associated with one or more spinning heads 8, operable independently of each other, within the same series 28,40 of spinning heads 8 or on different series 28,40 of spinning heads 8.
  • the route which the packages 24 must complete from the forming position 32 to the unloading position 36, passing through the intermediate holding position 48, is preferably facilitated by the provision of chutes 64 in correspondence with said series 28,40.
  • the chutes 64 connect said forming positions 32, the intermediate holding position 48 and the unloading position 36 are arranged along a transverse direction T-T, preferably perpendicular to said longitudinal direction X-X.
  • said chutes 64 are inclined downwardly, passing from the forming positions 32 towards the package unloading belt 44, so as to facilitate the unloading of the packages 24 and to connect with the latter.
  • Such inclination of the chutes 64 must be appropriately established so as not to cause the packages to move too fast or too slow, thus avoiding the risk that some packages, by rubbing on the edges of the chute 64, may stop along the inclined plane.
  • the open-end-type spinning apparatus comprises at least one control unit programmed to oversee the operation of the entire apparatus, coordinating the operation of the various spinning heads 8.
  • control unit is programmed to:
  • control unit is programmed to simultaneously block several formed packages 24" of a same series 28,40 of open-end spinning heads 8, by means of the holding means 52.
  • control unit is programmed so as to reach a predetermined number of formed packages 24" on a same series 28,40; the formed packages 24" are released from the respective intermediate holding positions 48, allowing them to simultaneously roll as far as the package unloading belt 44 positioned centrally with respect to the apparatus 4. In this way, it is possible to unload all the formed packages 24" (in a predetermined number) of a specific series 28,40 in unison: in other words, one side or series 28,40 of the apparatus 4 is unloaded at a time.
  • control unit is programmed so that once all the formed packages 24" of a series 28,40 are positioned on the package unloading belt 44, the same starts moving and brings all the formed packages 24" , or only a predetermined number of them, towards one end of the apparatus 4 from where the formed packages are unloaded.
  • control unit is programmed in such a way that, by releasing the intermediate holding positions 48, the retention means 52 are placed in an active position so as to block a new package 24" in the intermediate holding position 48.
  • control unit is programmed so that, when the package unloading belt 44 is moving, the retention means 52 remain in the activation position and their deactivation is inhibited to prevent the formed packages 24" from going past the intermediate holding position 48 and being sent to the package unloading belt 44.
  • the control unit is programmed so that the forming packages, 24', which during the unloading step of the formed packages 24" from the intermediate holding position should reach a given length, are made to remain in the forming position for a given number of meters of yarn, to then be stopped and unloaded into the intermediate holding position against the retention means 52, which in the meantime will be reactivated.
  • control unit is programmed in such a way that the package unloading belt 44, arranged centrally with respect to the apparatus 4, makes at least one complete half turn before beginning the package unloading step. In this way, the control unit ensures that all the formed packages 24" have been unloaded and ensures that it is in an empty belt condition.
  • the apparatus allows a method to be obtained for unloading a package comprising the steps of:
  • the step is provided to simultaneously block several formed packages 24" of a same series 28,40 of open-end spinning heads 8 using the retention means 52.
  • the single spinning head 8 knows when a package 24" produced therefrom has been unloaded and also when the formation of a new forming package 24' has started again: in effect, it is from that moment that the counting of the length begins. Therefore, the control unit, which manages all the spinning units 12, knows how many packages 24" have been deposited in the intermediate holding position 48.
  • the formed packages 24" Upon reaching a predetermined number of formed packages 24" on the same series 28,40, the formed packages 24" are released from the respective intermediate holding positions 48, allowing them to simultaneously roll as far as the package unloading belt 44 positioned centrally with respect to the apparatus 4.
  • the predetermined number of formed packages 24" arranged in the intermediate holding position 48 on a given series 28,40 will be less than or equal to the total number of spinning heads 8 of the same series.
  • the retention means 52 is placed in the active position so as to block a new formed package 24" in the intermediate holding position 48.
  • the formed package 24" is removed from the package unloading belt 44 and then from the action radius of the photocell, and the package unloading belt 44 advances again until the next formed package 24" is intercepted by the photocell which stops the package unloading belt 44.
  • This operation is repeated until all the formed packages 24" on the package unloading belt 44 are unloaded.
  • the retention means 52 When the package unloading belt 44 is moving, the retention means 52 remain in the activation position and their deactivation is inhibited to prevent the formed packages 24" from going past the intermediate holding position 48 and being sent to the same package unloading belt 44.
  • the package unloading belt 44 equipped with a system for recognizing the position thereof (for example a slot on the belt and its relative photocell), enables the possibility of starting a cycle by lowering the package stop bar 56 on one of the two series 28,40.
  • the new unloading cycle may be activated on each of the two series 28,40, i.e. the two faces of the apparatus 4: alternating therefore is not necessary, since the apparatus with faces or series 28,40 is independent, and thus able to work different counts with very different package formation times, the number of predefined packages for the start of the cycle may also occur several times in succession on the same face or series 28,40.
  • the open-end-type spinning apparatus and the method for unloading a package from an open-end-type spinning apparatus according to the invention allow the drawbacks presented in the prior art to be overcome.
  • the doffing procedure may not start if the package unloading belt is full: this is because the package that should be doffed could hit another previously unloaded package that is already on the belt.
  • Another advantage of the present invention is provided in the fact that a single package unloading belt may be used, while keeping separate the different lots of yarn produced on each side of the spinning apparatus.
  • the package unloading belt will not risk being loaded with side-by-side packages and may be emptied without problems.
  • the apparatus of the present invention is also economical to produce and to manage.
