Definitions

  • the invention relates to an apparatus for supplying continuous spinners (so-called ring-spinning machines) with material in bobbins - which are held in a position above the work groups of the spinner and made to hang down - comprising: a framework longitudinally extending along the corresponding spinner; on said framework guide means for a carriage movable along said framework; for each section of the work groups of each front fed by said apparatus a station for the storage of the full bobbins and the withdrawal of reeled off pipes; and on said carriage means for handling the full bobbins and the reeled off pipes.
  • Apparatuses of this type are known in which, for each work group, transfer and overturning means are provided in order to move mandrels for the support and retention of the rove bobbins from a position in which said bobbins are handled over by the handling means located on the carriage, to the individual mandrels, to a feeding position at the underlying work groups.
  • transfer and overturning means are provided in order to move mandrels for the support and retention of the rove bobbins from a position in which said bobbins are handled over by the handling means located on the carriage, to the individual mandrels, to a feeding position at the underlying work groups.
  • One 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.
  • an apparatus of the above mentioned type is characterized in that each of said stations comprises a first support for receiving feeding bobbins, i.e. the bobbins from which the rove is drawn for the spinning, and a second support for receiving full bobbins standing by for a successive replacement and that said means on the carriage for the handling of bobbins and of reeled off pipes comprise, for each spinners front to be supplied, a support for receiving a set of bobbins during the replacement phase of said bobbins.
  • feeding bobbins i.e. the bobbins from which the rove is drawn for the spinning
  • second support for receiving full bobbins standing by for a successive replacement
  • said means on the carriage for the handling of bobbins and of reeled off pipes comprise, for each spinners front to be supplied, a support for receiving a set of bobbins during the replacement phase of said bobbins.
  • said support rigidly connected to the carriage is placed at the same height as said first support of the station for the storing and unwinding of the bobbins, in which the bobbins feeding the rove to the work groups are disposed.
  • the full bobbins and/or the reeled off pipes of the exhausted bobbins are borne by mandrels provided with retractable expansion means for the engagement and disegngament of the bobbins and/or the pipes, said mandrels being carried by a supporting frame which is moved by said handling means disposed on the carriage.
  • mandrels On each frame 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 work groups of the spinner front to be supplied.
  • said first and said second support for receiving the feeding bobbins and the full bobbins standing by for a subsequent replacement, and said support on the mobile carriage comprise supporting profiles for the frame.
  • Said support for receiving the full bobbins standing by for their replacement may be disposed above and in correspondence of the receiving support for the feeding bobbins, and the supporting profiles of the upper support are in such case able to be withdrawn.
  • the means for handling the bobbins and the reeled off pipes 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 spinner. 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 feeding 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 spinner to be supplied between two fronts of said spinners, said carriage carrying two 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 spinners extending parallel one to the other.
  • the following description refers to an apparatus symmetrically disposed with respect to a spinner, capable of supplying the two fronts of spindles of the same spinner. However, it is not excluded. that an apparatus of similar type may be disposed between two side-by-side disposed spinners for the supply of bobbins to the 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 bobbins to the work groups of the spinner 1.
  • Said carriage 9 is able to slide in the direction of arrows f9 (Fig.6) along the whole extension of the spinner while picking up from a carriage or other stacking device, disposed at one end of same spinner, the bobbins to be fed to the various work groups, and picking up from each work group the reeled off pipes to store them in a suitable container located at the opposite end or at other suitable position with respect to the spinner 1.
  • the work groups or spindles 3A and 3B of the two work fronts of spinner 1 are grouped into sections, the spindles of each section being supplied simultaneously with rove bobbins.
  • each section of spindles or work groups comprises four of said spindles (see Fig.6).
  • Supports 11 and 13 able to support a frame 15 carrying a set of mandrels (eight in the drawing) are combined to each section of work groups.
  • 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 pipes to be picked up from or feed to the work groups of spinner 1.
  • a slide 21 is movable transversally 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 system 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 supports 23 for each of the two fronts of spinner 1 to be supplied, said supports 23 being disposed at the same height as the supports 11 of the framework 5.
  • 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 rove from the bobbins 27 has replaced the rove reeled off from bobbins 25.
  • the reeled off pipes 25 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 reeled off pipes from the support 11.
  • Fig.5 shows the following phase of displacement of frame 15 carrying the full bobbins 25 from the support 23 solid to the carriage, to the lower support 11 of the framework 5.
  • the cylinder-piston system 19 causes the reeled off pipes to raise according to arrow f6, thrust members 30 carried by carriage 9 push the frame 15 carrying the full bobbins 27 from the support 23 to the support 11 according to arrow f8.
  • the upper 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 0 and by the support 23.
  • carriage 9 After having lifted the frame 15 carrying the reeled off pipes 25, and pushed the frame carrying the full bobbins 27 into the feeding position, i.e. onto supports 11, carriage 9 is able to carry the reeled off pipes 25 from the just supplied work group section to a pipe collector located at one of the ends of the spinner to be fed or at any other suitable position.
  • the cylinder-piston system is moved by the slide 21 in the direction of arrow fl0 transversally with respect to spinner 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 reeled off pipe 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 pipes is obtained, while the frame 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 reeled off pipes, it can carry out the positioning of a set of bobbins 32 also borne by a frame 15, which are positioned into the support 13 above the feeding bobbins 27. To this end, carriage 9 moves in correspondence of the position wherein the full bobbins are stored, e.g. to one end of spinner 1, where small carriages in which the full 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 spinner 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 feeding bobbins to allow an automated supply of new bobbins to the individual sections of the work groups 3A, 3B.
  • the time required for the working of the individual feeding rove 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 supports 13 with stock bobbins 32.
  • the described apparatus even allowing an elevated automation of the supply operations in a continuous spinner, 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 spinner 1.
  • this joining operation is particularly handy as it can be carried out easily and with enough time before the rove unwinding from the pipes 25 is completely reeled off.
  • the apparatus according to the invention provides for the temporary side-by-side arrangement of pipes which are about to be completely reeled off and of bobbins to be replaced. After having performed the joining of the free ends 29 of the roves wound on bobbins 27, the end portions of the roves unwinding from the reeling off pipes 25 can be cut away.
