Definitions

  • the invention relates to an attending device of the spinning machine which is in its top section equipped with an upper travel for adjustable mounting onto the top section of the spinning machine and in its lower section is equipped with a supporting means for stabilisation in working position in front of an operating unit of the spinning machine.
  • Spinning machine comprises at least one row of operating units along which the attending device mounted on the machine on guiding means is travelling.
  • the attending device in its top section is provided with pulleys rolling on these tracks or rails, through which the defined motion of the attending device along the row of operating units is enabled.
  • This embodiment also disables a simple taking out of the spinning unit, as it is necessary to disassemble also a part of the guiding, by which an interruption of the guiding occurs, over which the attending device according to this embodiment cannot run over without re-assembly of the spinning unit, which restricts operation of the attending device.
  • the attending device is equipped with swinging supporting means which, after arrival of the attending device to the operating unit being attended, swivels and leans against the defined surface in the operating unit, while during leaning against it presses on this surface, slightly pushes away the attending device from the operating unit, thus delimits the clearance in travelling mechanism of attending device.
  • the disadvantage of this embodiment is a demanding driving of the swinging supporting means which must overcome the weight of a whole attending device for the purpose to slightly push away this attending device from the operating unit and to bring the attending device on each operating unit into the required defined position towards the means of operating unit.
  • the goal of the inventioninvention is to remove or at least minimise the disadvantages of the present state of art.
  • the goal of the inventioninvention has been achieved by the attending device of spinning machine, whose principle consists in that the supporting means is a part of an adjustable support, which is in an adjustable manner in the direction from and to the spinning machine mounted on the attending device, and which is provided with means to fit on a contact surface on the spinning machine in working position of the attending device, while on the adjustable support there is mounted at least one operating means of the attending device.
  • This device is simple and functional and it enables its troublefree incorporating into the attending device. Another advantage of this device is that it is not necessary to use the lower guiding of the attending device and so this embodiment reduces an economical demand of the machine. Another advantage of the device according to the invention is that it is possible simply without necessity to disassemble further parts to remove the spinning unit. Another advantage of the device according to the invention is that it enables to the attending device to run over the operating units without the spinning unit, so that even after removal of the spinning unit from the operating unit or from several operating units of a row of operating units, the operation of the attending device for remaining operating units is not restricted. Another advantage of the device according to the invention is that operating means of the attending device do not need to have long travel for performance of their operations, which further reduces an economic demand of the machine, at the same time increases the rigidity of a system of operating means on the attending device.
  • the adjustable support is formed by a frame body having the shape of "U" letter, which by its upper ends is in swinging manner mounted in the attending device and it is coupled with a drive, while in the lower section of the frame body there is mounted a supporting pin to fit on a contact surface in the spinning machine in operating position of the attending device.
  • the adjustable support is formed by a straight-lined body mounted in swinging manner in the attending device, while the straight-lined body is coupled with the drive, on its free end is provided with supporting means and on it there is mounted at least one operating member of the attending device.
  • the drive of the adjustable support is formed by a linear drive whose one part in an interval from upper ends of the frame body of adjustable support is coupled with adjustable support, and whose second part is coupled with frame of the attending device.
  • the drive of the adjustable support is formed by a rotating drive, with which at least one from upper ends of the frame body of adjustable support is coupled.
  • the invention is schematically represented on the drawing, where the Fig. 1 represents a view to arrangement of the attending device on a spinning machine, and the Fig. a view to arrangement of the attending device from the Fig. 1 in direction of arrow A in the Fig. 1 .
  • Attending device 1 of a spinning machine comprises the upper travel 2 in the represented example of embodiment formed by the first travel joint 20 and the second travel joint 21.
  • the first and second travel joint 20, 21 are mounted in an adjustable manner on travelling tracks 3 mounted continuously along a whole length of the spinning machine, i.e. along at least one row of operating units, while at the double sided machine the travelling tracks 3 may contain also the "turning" for running over of the attending device 1 to the second side of the machine.
  • Each side of the machine may also be provided with at least one own attending device 1 or the attending devices 1 from each side of the machine may suitably co-operate on both sides of the machine, etc.
  • the spinning machine further comprises at least one row of operating units, out of which each in the represented example of embodiment comprises a place for the can 4 with fibre sliver 40, the spinning unit 5 for transforming the fibre sliver 40 into a yarn 50, which is drawn-off from the spinning unit 5 and wound onto the bobbin 60 by means of winding mechanism 6.
  • Attending device 1 comprises individual mechanisms necessary for their activity on the machine.
  • the attending device also comprises the in swinging manner adjustable support 7 , which at motion of the attending device 1 is situated in interval from the machine, and which when the attending device 1 stops in front of the operating unit that should be attended by the attending device 1 , swings out towards the machine and it touches the specified contact surface ofoperating unit, in represented example of embodiment it touches the face side 51 of the spinning unit 5. In the not represented example of embodiment it touches another suitable surface on the operating unit or on the machine.
  • the in swinging manner adjustable support 7 is provided with a drive 70 connected to the control device and securing its motion towards and from the machine.
  • the adjustable support 7 is formed by a frame body 71 having the shape of "U" letter, which by its upper ends 710 is in a swinging manner mounted in a frame of the attending device 1.
  • the swinging drive of the in swinging manner adjustable support 7 is formed by a linear drive, whose movable member 700 is in interval from upper ends 710 of the frame body 71 coupled with the frame body 71, while the fixed member 701 of linear drive is mounted on the attending device 1.
  • the moveable member 700 of linear drive is mounted on the attending device 1 and the fixed member 701 of linear drive is coupled with the frame body 71 of adjustable support 7.
  • the in swinging manner adjustable support 7 is coupled with the rotating drive.
  • the supporting pin 711 in the represented example of embodiment contacting the respective place on the machine or on the operating unit, e.g. fitting on a face side of the spinning unit 5 of the operating unit being attended.
  • At least one operating means 10 of the attending device e.g. at rotor spinning machines it is the spinning-in head, the searching nozzle of yarn end on a bobbin etc., which at least partially is saving the moveable apparatus of the respective working member 10, or working members 10 of the attending device 1, which moreover are always in the same and exact initial position, secured in an excellent and simply way, towards the means of an machine operating unit being attended.
  • adjustable support 7 is performed in another suitable way, e.g. by one rod or tube (a straight-lined body) one-sided mounted in swinging manner in the attending device, coupled with the drive connected to the controlling device and provided with supporting means on its free end, while on the straight-lined body there is mounted at least one operating member 10 of the attending device 1.
