Definitions

  • the present invention relates to the field of the textile industry, especially the benches with spindles for long fibers and has for object a device for controlling the fins and the coils of such a spindle bench.
  • the command fins and coils is achieved through shafts longitudinal driving said coils and fins, in sets or sections, generally from sixteen, for each section or set, to by means of a pair of bevel gears for the angle transmission of vertical shafts, which in turn drive, via sprockets and belts notched groups of fins and coils.
  • One such embodiment is especially known from DE-U-70 46 263.
  • a spindle bank coil is carried out by a rewinding the wick of the type with juxtaposed turns, so as to achieve a first layer, a following layer being superimposed on the previous and the winding stroke being reduced with each change of layer to obtain a double conical trunk coil, the tension of the twisted wick to be kept at a constant value.
  • the speed of the fins being fixed at a value constant, it is advisable, to maintain a constant tension of the wick, whatever the layer considered, that is to say whatever the diameter of the reel, to reduce, with each change of layer, the speed of coils so as to maintain a constant winding speed.
  • This speed variation of the coils is obtained mechanically, the control shaft of the coils receiving, by through a differential, a rotational movement which is the constant speed component from the main motor and the variable speed from the cone and belt variator. Furthermore, this last drive causes the vertical movement of the reel carriage.

  • FIG. 1 of the accompanying drawings shows, by way of example, a pin bench for long fibers which includes sections 1 of pinions 2 fins control, hereinafter referred to as sections 1 of fins 2, and sections 3 of pinions 4 for reel control, designated below sections 3 of coils 4, these sections being connected to a device for ordered.
  • sections 1 of fins 2, which are in the same vertical plane as the sections 3 of coils 4, are shown offset relative to the latter.
  • Each section 1 of fins 2 and each section 3 of coils 4 are provided with an individual drive means 5, respectively 6 in the form of individual motors.
  • the fins 2 and the coils 4 of each group are at least in threes and are linked together by through respective belts 9 and 10 and each individual motor 5 or 6 drives, by means of two drive belts 7, respectively 8, two contiguous groups of fins 2, respectively of coils 4, not interconnected by their respective connecting belts 9 and 10.
  • the individual training means 5, respectively 6, are advantageously individual driving engines, each by through at least one drive belt 7, respectively 8, at least one group of fins 2, respectively of coils 4.
  • the fins 2 and the coils 4 of each group are advantageously at least by three and are interconnected by means of respective belts 9 and 10.
  • each individual motor 5 or 6 drives two groups of fins 2 or coils 4 via the connecting belts 7 or 8.
  • a fin 2 and a coil 4 of each group are common to two groups contiguous and are connected to the respective connecting belts 9 and 10 of the two groups and, step by step, all groups of fins 2 and coils 4 are interconnected, so that the drive of all the fins 2 and coils 4 is provided.
  • these contiguous groups of fins 2 and coils 4 are not not interconnected by their respective connecting belts 9 and 10.
  • Each section 1 of fins 2 and each section 3 of coils 4 are preferably formed by sixteen fins and by sixteen coils.
  • the speeds of rotation of the fins 2 and of the coils 4 of each section 1 and 3 are synchronized with each other via a device 11 of mechanical and / or electronic synchronization.
  • the synchronization device 11 may consist of a belt 12 connecting the sections 1 of fins 2 between them and by a longitudinal connecting shaft 13 connecting together the ends of the axes of the motors 6 for driving each section 3 of coils 4.
  • Figure 2 of the accompanying drawings shows a variant of embodiment of the invention, in which the part of the device synchronization 11 relating to the connection of the sections 1 of fins 2 to one another consists of the connecting belt 9 of the group of fins 2 at the end of a section 1, possibly with the interposition of a tensioner 14.
  • FIG. 3 represents an alternative embodiment of the invention, in which the synchronization device 11 consists of a shaft longitudinal 15 connecting the axes of the motors 5 of each drive section 1 of fins 2 and by a belt 16 connecting sections 3 of coils 4.
  • sections 3 of coils 4 can also be connected between them by means of the connecting belt 10 of the group of coils 4 end of a section 3, possibly with interposition a tensioner.
  • the device synchronization 11 consists of two belts 17 and 18 connecting respectively the sections 1 of fins 2 and the sections 3 of coils 4 therebetween.
  • the sections 1 of fins 2, respectively the sections 3 of coils 4 can also be connected together by through the respective connecting belt 9 or 10 of the group fins 2 or coils 4 end of a section 1 or 3, possibly with interposition of a tensioner, said connecting belts 9 and 10 forming the synchronization device 11.
  • the device synchronization 11 in the form of longitudinal connecting shafts 19 and 20 connecting respectively the axes of motors 5 and 6 for driving sections 1 of fins 2 and 3 of coils 4 (Figure 5).
  • the synchronization device 11 consists of trees longitudinal links 21 and 22 arranged between bevel gearboxes cooperating with the axes of the respective motors 5 and 6 for driving sections 1 and 3 of fins 2 and of coils 4.
  • the drive motors 5 and 6 are mounted on the spindle benches with a vertical arrangement of their axis.
  • the synchronization device 11 can also be constituted by at least one connecting belt arranged between the respective motors 5 and 6 for driving sections 1 of fins 2 and sections 3 of coils 4.
  • the axes of the motors 5 and 6 are also vertical.
  • the synchronization device 11 in the form of an electronic device constituted by a control unit 23 and by variators 24 speed electronics controlled by said control unit and each assigned to one or more motors 5, respectively 6 for driving sections 1 of fins 2, respectively 3 of coils 4.
  • the speed of the coils 4 can be controlled very precisely to that of the fins 2, so as to maintain a predetermined tension of rewinding the wick.
  • the rotational speeds of motors 5 and 6 for controlling the fins 2, respectively the coils 4 can be set to perfectly equal values.
  • the device for controlling the fins and coils of a bench with pins for long fibers allows, relative to the pin banks known to date, to delete and replace a large number of mechanical elements by electrical components. It As a result, regular maintenance and lubrication, necessary for reasons for the reliability of operation of each mechanical element of transmission, can be removed and that the manufacturing cost and corresponding assembly, pertaining to required precision assemblies to ensure quality mechanical transmission, can also be considerably reduced.
  • Another advantage of the invention lies in the modularity of the control of the coils 4 and the fins 2, which makes it possible to adapt to less cost the length of the machine at the request of the user. This is in particular possible because each module is made up of the same parts and has the same number of coils 4 and fins 2.
  • the bench pins can be equipped with the choice of several modules, the number of references of documents to be managed can, therefore, be reduced to correspondence.
  • control of a spindle bench by electronics control allows an approval of use and adjustment. Indeed, the adjustment time of the coil formation parameters is reduced and the changing these parameters can be performed electronically without change of pinions.
