Definitions

  • the invention relates to an apparatus for continuously operating ring spinning machines or the like having a multitude of working units, a framework extending along said spinning machine, guide means for a carriage moving along said framework, the carriage having means for supplying each section of the spinning machine with full roving bobbins being transferred to a storage station and means for removing empty tubes, the framework being provided with unwinding stations for the unwinding of bobbins, the storage station and the unwinding station being arranged above the spinning units.
  • An apparatus of this type is known from EP-A-0240473.
  • transfer and overturning means are provided in order to move mandrels for the support and retention of the roving bobbins from a position in which said bobbins are handled over by the transferring means located on the carriage, to the individual mandrels, to a feeding position at the underlying working units.
  • This apparatus therefore requires relatively complex mechanisms for a considerable number of working units, as each spinning machine front can be provided with more than 200 spindles.
  • EP-A-0213962 a device is described, for replacing empty tubes by roving bobbins combined with the piecing of the rovings on spinning machines.
  • a first support for unwinding bobbins is provided along the spinning machine and a second support for full roving bobbins extends parallel to said first support.
  • a carriage carries means which replace the empty tubes on the first support with full roving bobbins standing by on the second support.
  • the carriage is provided with a complex mechanism for piecing the tail of the almost reeled off rovings with a new roving.
  • Said carriage is however not provided with means for supplying full roving bobbins along said second support.
  • the object of the invention is to provide an apparatus of the above mentioned type, which has substantially simpler and less expensive mechanisms ensuring, however, a high degree of automation of operations for the supply and replacement of the bobbins.
  • the storage and unwinding supports are arranged above one another and the transferring means arranged on the carriage provides for:
  • the transition support on the carriage may be placed, in this case, at the same height as said unwinding support.
  • the full roving bobbins and/or the empty tubes are borne by mandrels provided with retractable expansion means for the engagement and disengagement of the bobbins and/or the tubes, said mandrels being carried by a supporting frame which is moved by said transferring means disposed on the carriage.
  • mandrels are predisposed in a number and position corresponding to the number and position of the bobbins to be disposed in each section of the working units of the spinning machine front to be supplied.
  • said first and said second support for receiving the unwinding bobbins and the full roving bobbins and said transition support on the mobile carriage comprise supporting profiles for the frame.
  • Said storage support for receiving the full roving bobbins may be disposed above and in correspondence of the unwinding support for the unwinding bobbins, and the supporting profiles of the upper support are in such case able to be withdrawn.
  • the means for transferring the bobbins and the empty tubes may comprise at least a cylinder-piston system for the motion of said frames, said system being displaceable in transverse direction with respect to the supplied spinning machine, and further means for the displacement of a frame provided with mandrels from the support located on the carriage to the support for receiving the unwinding bobbins, said means being operable independently of said cylinder-piston system.
  • the means for the displacement of the frame may comprise, e.g. a chain or the like able to slide in sliding guides.
  • the framework of the apparatus according to the invention may be disposed in central and symmetrical position relative to the spinning machine to be supplied between two fronts of said spinning machines, said carriage carrying two transition supports, symmetrically located with respect to the framework, for receiving a set of bobbins during the replacement phase of the same bobbins.
  • said framework may be disposed between opposite fronts of two spinning machines extending parallel to one another.
  • the following description refers to an apparatus symmetrically disposed with respect to a spinning machine, capable of supplying the two fronts of spindles of the same spinning machine.
  • an apparatus of similar type may be disposed between two side-by-side disposed spinning machine for the supply of bobbins to the working units (i.e. work groups) of two facing fronts of said spinners.
  • a framework 5 carrying a guide 7 longitudinally extending throughout the spinner; on said framework a carriage 9 is able to move for the supply of full roving bobbins to the working units of the spinning machine 1.
  • Said carriage 9 is able to slide in the direction of arrows f9 (Fig.6) along the whole extension of the spinning machine while picking up from a carriage or other, stacking device, disposed at one end of same spinning machine, the bobbins 27 to be fed to the various working units, and picking up from each working unit the empty tubes 31 (i.e.
  • each section of spindles or working units comprises four of said spindles (see Fig.6).
  • a lower unwinding support 11 and an upper storage support 13 able to support a frame 15 carrying a set of mandrels (eight in the drawing) are combined to each section of working units.
  • Said mandrels 17, of known type have snap retractable expansion means, for example elastic flyers, for the engagement and the release of bobbins and/or empty tubes to be picked up from or fed to the working units of spinning machine 1.
  • a slide 21 is movable transverse to the longitudinal extension of the guide 7 for each front of spindles 3A, 3B, said slide carrying a cylinder-piston system 19 for the handling of frames 15 in a manner described below.
  • one of said slides and one of said cylinder-piston systems are indicated in greater details, the other slide and the other system are only roughly indicated being symmetrical to the first ones. It is also possible to use a single slide 21 and a single cylinder-piston system.
  • the carriage 9 carries also transition supports 23 for each of the two fronts of spinning machine 1 to be supplied, said transition supports 23 being disposed at the same height as the supports 11 of the framework 5.
  • Figs. 1 to 5 the phases of supplying full bobbins to the individual sections of spinning machine 1 are described with reference to Figs. 1 to 5.
  • Fig. 1 on the frame 15 located on the lower support 11, substantially reeled-off unwinding bobbins 25 are borne by the corresponding mandrels 17. Therefore the replacement of the unwinding bobbins must be carried out.
  • On the upper support 13 is a similar frame 15 whose mandrels carry full roving bobbins 27. Said frame 15 has been laid down in this position by the carriage 9 upon a previous supply stage.
  • the carriage 9 moves in correspondence to the section in which the replacement is to be performed and picks up the frame 15 together with bobbins 27, located on the supports 13, by means of the cylinder-piston system 19.
  • the full bobbins 27 are brought in correspondence of support 23, which is rigidly connected to carriage 9, and released on said support upon lowering of the cylinder-piston system 19 in the direction of arrow f2 (Fig.3).
  • Fig.4 shows how the new roving from the bobbins 27 has replaced the roving reeled off from unwinding bobbins 25.
  • the empty tubes 31 may at this point be collected by the cylinder-piston system 19 of carriage 9 which to this end, after having placed frame 15 with bobbins 27 on support 23, moves transversally in direction of arrow f3 towards the center line of carriage 9, and lowers down again according to arrow f4 to pick up the frame with the empty tubes 31 from the support 11.
  • Fig.5 shows the following phase of displacement of frame 15 carrying the full roving bobbins 27 from the transition support 23 solid to the carriage, to the unwinding support 11 of the framework 5.
  • the cylinder-piston system 19 causes the empty tubes 31 to raise according to arrow f6, thrust members 30 carried by carriage 9 push the frame 15 carrying the full roving bobbins 27 from the transition support 23 to the unwinding support 11 according to arrow f8.
  • the storage support 13 solid to framework 5 is provided with supporting flyers as those shown in Fig.6, which may take up a withdrawn position (shown in hatched lines in said Fig.6) to allow the transit of the frame 15 to be picked up.
  • the lower support 11 may instead be made up of fixed flyers.
  • the thrust members 30 may consist in particular of a chain or the like, sliding within guide members carried by the carriage 9 and by the transition support 23.
  • carriage 9 After having lifted the frame 15 carrying the empty tubes, and after having pushed the frame carrying the full roving bobbins 27 into the feeding position, i.e. onto unwinding supports 11, carriage 9 is able to carry the empty tubes 31 from the just supplied working unit to an empty tube collector located at one of the ends of the spinner to be fed or at any other suitable position.
  • the cylinder-piston system 19 is moved by the slide 21 in the direction of arrow f10 transversally with respect to spinning machine 1 up to be positioned outside the set of supports 11, 13.
  • Carriage 9 is thus free to move along guides 7 up to the position in which the empty tubes collection point is located, where cylinder-piston system 19 is able to lower according to arrow f12 (see Fig.7) and thus release the reeled off pipes 25. Since the mandrels 17 are provided with snap retractable expansion means, by pressing the lower portion of the reeled off pipes on a reference plane, the retraction of the expansion means and then the release of said empty tubes 31 is obtained, while the frame 15 remains engaged to the cylinder-piston system 19 for subsequently drawing a set of full bobbins.
  • carriage 9 when carriage 9 has performed the operations for the replacement of empty tubes 31, it can carry out the positioning of a set of bobbins 32 also borne by a frame 15, which are positioned into the storage support 13 above the full roving bobbins 27. To this end, carriage 9 moves in correspondence of the position wherein the full roving bobbins are stored, e.g. to one end of spinner 1, where small carriages in which the full roving bobbins coming from the previous workings are predisposed in positions corresponding to those of mandrels 17 on the relevant frames 15.
  • carriage 9 can carry one or two cylinder-piston systems 19, in the latter case each cylinder-piston system serving one of the two fronts of spinning machine 1.
  • the use of two cylinder-piston systems 19 and of corresponding slides 21 allows the simultaneous supply of opposite sections of work groups 3A, 3B with a reduction of work time.
  • the system shall be provided with sensors able to detect the reeling off condition of the unwinding bobbins to allow an automated supply of new roving bobbins to the individual sections of the work groups 3A, 3B.
  • the time required for the unwinding of the individual roving bobbins is relatively long, there is time available to allow the carriage 9 and the other relevant equipment for the handling of frames 15 to supply the various storage supports 13 with stock bobbins 32.
  • the described apparatus even allowing an elevated automation of the supply operations in a continuous spinning machine, has an extremely simplified structure as it does not require bobbin and pipe handling mechanisms for the individual sections or for the individual work groups of the spinner 1.
  • the only handling members and mechanisms are disposed on the carriage 9, while framework 5 does not have any auxiliary mechanism. This allows great saving and simplifications of the apparatus, as all the handling mechanisms are single or at the most double in case carriage 9 is equipped with two slides 21 and relevant cylinder-piston systems 19, while only fixed supports 11 and 13 are disposed in correspondence of the work groups of spinning machine 1.
  • this joining operation is particularly handy as it can be carried out easily and with enough time before the roving unwinding from the bobbins 25 is completely reeled off.
  • the apparatus according to the invention provides for the temporary side-by-side arrangement of unwinding bobbins which are about to be completely reeled off and of full roving bobbins to be replaced.
