Definitions

  • the present invention relates to assembling reels immediately after winding and in the discharge phase from the winding machine.
  • the object of the present invention is the assembling of two reels immediately after winding and before discharge from the winding machine, the two reels being wound differently.
  • the object of the present invention therefore is to provide a method and a device for winding and assembling the reels before discharge from the winding machine so as to avoid subsequent manipulation and handling of the reels themselves, such manipulation and handling result in a loss of time, breakage, degradation of the product, delays and more waste of space, etc.
  • One further object of the invention is that of executing all the operations in a manner obviating the intervention of the operator.
  • Conveyor transport means for wound reels are known from DE-C-804173 and hence are not claimed.
  • DE-A-2455553 envisages the production of different reels on the same winding machine.
  • the present invention instead envisages the simultaneous production, on the same winding machine of reels whose sizes are proportioned in relation to the difference in the yarn quantity required in a doubling and simultaneous double-twisting operation.
  • the invention is advantageously realized and the objects are achieved allowing thus the exploitation of the numerous advantages, by providing a winding machine which is regulated in such a way that the reels are produced on some heads in a manner that renders these reels suitable, for the upper position and on other heads the reels produced are suitable for the lower position.
  • the formation heads of the winding machine can be arranged alternately.
  • the formation heads are preset so that one half produces reels for the upper position and one half produces reels for the lower position.
  • the differently-formed reels are then mechanically paired as soon as they leave the winding heads and before their removal from the winding machine.
  • winding heads are preset alternately, there will be a mechanism that independently, for instance, for each pair of heads, takes the two reels and combines them by axially inserting them on an auxiliary support, for example, of the type described in DE AS 1.560.271.
  • Such a mechanism or a device may be arranged one for each pair or more winding heads, or otherwise one for each machine.
  • the reel assembling device may be stationary or may be mounted to travel along the side of the machine in such a way as to serve all the winding heads.
  • the reel assembling device can be disposed at the front of the winding machines and serves all the winding heads, nevertheless such an assembling device may be arranged to travel.
  • the assembling may be achieved by the axial insertion of the extremity of one reel spool into the extremity of the other reel spool when, for example, the spools used are of the type described in DE-A-3016015.
  • the invention provides a method and a device for winding reels and assembling the wound reels as claimed in claims 1 and 9 respectively.
  • 10 is the upper reel which is in a winding-off stage, reeling off a filament 11 at a lower tension
  • 1 10 is the lower reel whose filament 111 is being withdrawn at a higher tension which induces in the filament 111 itself an elongation which results in the possibility that the reel 110 has less filament than the reel 10
  • 12 see Fig.
  • 13 is a schematic and generic representation of a double twist spindle within which are arranged the reels 10 and 110; 14 is the spool of reel 10 and 1 14 is the spool of reel 110; 15 is the insertion and coupling zone of the spools 14, obtained, for example, by the cooperation of the portion 16 with the portion 17 of the spool as taught for example in DE-A-3016015; 18 indicates an auxiliary tube as taught, for example, in DE-B-1.560.271; 19-119 are the spools of reels 10 and 110 respectively in the case of insertion with the help of auxiliary tube 18; 20 are schematically the winding heads of the winding machine generically and schematically indicated by 21, such winding heads 20 produce the reels 10; 120 are schematically the winding heads of the winding machine 21 that produce the reels 110.
  • the winding machine 21 is substantially divided into two halves, one half equipped with heads 20 which produce reels 10 and the other half heads 120 which produce reels 110.
  • the heads 20 and 120 may be disposed alternately or in alternate groups.
  • the discharge conveyer belt 22 serves the winding heads 20 which in turn produce the reels 10
  • the discharge conveyer belt 23 serves the winding heads 120 that produce the reels 110.
  • a microswitch 24 for sensing the end of travel of the conveyor belt 22 is actuated when a reel 10 arrives at the end of the conveyor belt 22.
  • a transfer device 25 transfers the reel 10 on to the discharge conveyor belt 23 or on to another conveyor or auxiliary means.
  • An intercepter barrier 26 acting on the belt 22 is actuated once a reel approaches the microswitch 24 and is raised when the said reel 10 has been transferred.
  • a microswitch 27 may be provided at the end of conveyor belt 23, or an auxiliary or other means of aggregation.
  • An interceptor barrier 28 acting on belt 23 is actuated when a reel 110 approaches the positioning zone.
  • a device 29 serves for the forced insertion of the terminal portion 16 of the spool 14 of reel 10 into the terminal part 17 of the spool 114 of reel 110.
  • a head 30 provided in device 29 exerts the pressure for assembling the spools 14 and 114 having as an abutment the microswitch 27 which raises said head, once the spools are assembled to free the assembling zone in order to permit the arrival of the subsequent spool 110.
  • the pivot axis of the microswitch 27 is shown as 32.
  • the means 33 consists of a jack which temporarily positions the head 30 in the assembling and discharge phase; the jack 34 moves the device 29.
  • the trolley of the device 29 is indicated by 35.
  • one device 29 can be provided for each pair of winding heads 20-120 in the case where said heads are arranged alternately.
  • the device 29 can be on the other hand arranged to travel along the side of the winding machine 21 at the reels 10-110 outlet end.
  • the device 29 can be equally suitable for threading two reels (one 10 and the other 110) on an auxiliary tube 18.
  • a device 41 is provided for picking-up, transferring and positioning the auxiliary tubes 18.
  • the said tube transfer and positioning device 41 substitutes also the group 27-31-32 acting as abutment and travel limiting means for the assembled reels 10-110.
  • the said transfer and positioning device 41 for auxiliary tubes 18 consists in the present example of a carriage 42 slidingly running on suitable vertical guide means 43.
  • Said vertical guide means 43 are mounted on a support 44, the carriage 42 being vertically displacable by means of a belt 45 connected thereto and coacting with a lower pulley rotatably mounted on said support 44 and an upper driving pulley 46 integral with the driving shaft of motor means 47.
  • the above-said transfer and positioning device 41 includes a pick-up device 48 for the auxiliary tubes.
  • Said pick-up device 48 consists in the example of a jack 49 horizontally anchored to the said carriage 42.
  • An expandable head 51 for picking up auxiliary tubes is arranged at the end of the piston rod 50 of the jack 49.
  • the head 51 is shown to consist of a chamber 52 on which a rigid bowl 53 is axially mounted having an external diameter slightly smaller than the internal diameter of the auxiliary tube 18.
  • the said bowl 53 is provided with circumferential slots 54 and internally lined with an inflatable rubber diaphragm 55.
  • the said chamber 52 is connected to a source of fluid under pressure (not shown) by means of flexible tube 56.
  • the said pick-up head 51 Being mounted on the end of the piston 50 of jack 49, the said pick-up head 51 is capable of being displaced both horizontally and vertically.
  • the reel assembling device can be provided with a device of known type capable of recovering and positioning the end of the yarn on the package.
  • the reels 10 and 110 are produced on winding heads 20-120 and are then combined by the assembling device 30.
  • the assembling can obviously be achieved by either a reciprocal insertion (example of Fig. 1 a) or by threading on an auxiliary tube (example of Fig. 1 b-5-6).
  • the carriage 42 is lowered in order to bring the picked up auxiliary tube to a predetermined position coaxial to the reels 10-110 which are to be inserted as they arrive on the conveyor means 23.
  • the rod 50 carrying the pick-up head 51, on which the auxiliary tube 18 is now clamped is extended towards the reels 10-110, whereby due to a coordinated movement of the device 30, the auxiliary tube 18 successively receives the two reels 10-110.
  • the auxiliary tube 18 is freed and thus falls, with the reels thereon, into a store or in a collection carriage (not illustrated).
  • each winding head produces reels 10 and 110 alternately; it is possible to apply the invention to winding machines with withdrawal arranged at the back but also on winding machines with withdrawal at the front; it is possible to substitute the discharge conveyor belts 22 and 23 by other means, for example a chute, a plate, a transporter removal arms, etc..., it is possible to arrange for the assembling device 30 to work horizontally, vertically, and in any other way desired; it is possible to arrange for the assembling device to include a device for orientating the reel; etc...; it is possible to provide motor means 47 in the form of a jack; it is possible to provide a store 40 positioned at the same height of the reels 10-110; it is possible to arrange for the reels 10-110 to move with respect to the auxiliary tube 18; etc....
