Definitions

  • the invention relates to a device for sheathing a spinning device as known, for example, from DE-A-3613163.
  • a shielding element for a cop is described on a textile machine, which is designed as a cylindrical cover, which is arranged below the race and can be moved up and down together with it.
  • the cover constantly surrounds the thick, lower part of the cop, so that no interference can arise from it.
  • the shortenable cover is either in the form of a bellows or in the form of a telescopic tube. The cover can therefore follow the movement of the spindle bench.
  • DE-A-3400327 describes a bell spinning device which has a bell which is surrounded by a stationary jacket with a small air gap.
  • the spindle and the coil are also surrounded by a jacket, the clear width of which, however, is so large that the electric motor can also move up and down inside.
  • the jacket surrounding the spindle has a lateral slot through which the support arm extends.
  • the jacket surrounding the bell and the jacket surrounding the spindle are to be opened, for example, to open a full bobbin and to repair a broken thread. For this purpose, they are divided lengthways, with the rear halves being arranged in a stationary manner on the machine frame.
  • the two covers described above have the disadvantage that they hardly allow easy access to the spinning station. This access should be guaranteed in the event of thread breaks or other manipulation at the spinning position, i.e. on the spindle or on the rotor of one Ring spinning machine or on the spindle and on the bell in a bell spinning machine.
  • the object of the present invention is to improve the sheathing of a spinning device of the type mentioned above in such a way that simple handling at the spinning position is made possible. This object is solved by the features of claim 1.
  • the invention has the essential advantage that a permanent covering of the spinning device is provided and, at the same time, this casing can be brought into an inserted position with very simple means.
  • suction is provided on the sheathing.
  • this suction also serves to dissipate the waste heat that is generated by the individual motor of the spindle.
  • Fig. 1 shows a bell spinning device with a bell 1 and an up and down movable spindle 2, which is driven by a single motor 3.
  • the bell 1 is also driven by a single motor 4.
  • the bell 1 and the single motor 4 are fixedly and immovably connected to the machine frame 5.
  • the spindle 2 with its single motor 3 are arranged on a spindle bench indicated by 6 up and down. However, it can just as well be reversed that the bells 1 can be moved up and down on a bell bank and that the spindles 2 are fixedly arranged with respect to the spinning machine.
  • a sheath, generally designated 7, consists of individual sleeve elements 8.
  • the uppermost part 9 of the sheath 7 is a solid cover which surrounds the bell with a small gap distance.
  • This part 9 is also firmly connected to the machine frame 5.
  • the lower edge 10 of the part 9 is projecting outwards.
  • the underlying sleeve element 8 has an inwardly projecting edge 11, so that there is a small distance between the outer wall of the part 9 and the inner wall of the sleeve element 8.
  • the lower edge of the sleeve element 8a is in turn formed with an outwardly projecting edge 12.
  • the sleeve elements 8b and 8c underneath are designed similarly to the sleeve element 8a, the diameter being larger in each case by the distance specified above.
  • the inwardly projecting edge 10 or 11 of the part 9 or the respective sleeve element 8a, 8b, 8c lies on the outwardly projecting edge 12 of the sleeve element lying above it.
  • Air inlet holes 13 are provided in the wall of the sleeve elements 8a, 8b and 8c just below the upper inwardly projecting edge 11.
  • the air inlet opening 13 of the lowermost sleeve element 8c is connected to a compressed air device denoted by 14.
  • each sleeve element 8a, 8b and 8c there is an outwardly projecting edge 15 which serves as a stop for the underlying sleeve element 8b or 8c.
  • the lowermost sleeve element 8c stands schematically with one Edition 16 just shown as corresponds to the upper edge of the single motor 3.
  • a suction 17 is connected to the inside of the casing 7 by a curved tube 18.
  • a lock 19 is provided on the machine frame 5, which can be brought into engagement with the upper, outwardly projecting edge 15 of the sleeve element 8c.
  • the locking device 19 consists of a lever arm 21 which can be rotated about a pivot point 20 and which is provided with a hook 22 at the bottom. The lever arm is rotated counterclockwise by a compression spring 23 against a stop 24.
  • FIG. 2 the same elements are now shown as in Fig. 1, with the casing now being brought into the inserted position.
  • the upper outwardly projecting edge 15 of the lower sleeve element 8c is held by the hook 22.
  • a hollow cylindrical space 25 is formed between the inserted sleeve elements 8a, 8b and 8c and the part 9.
  • Compressed air is blown into the air inlet openings 13 with the compressed air device 14, as a result of which the upper, inwardly projecting edge 11 of the sleeve element 8c and the lower, outwardly projecting edge 12 of the overlying sleeve element 8b are pushed apart.
  • the compressed air is blown into the air inlet opening 13 of the sleeve element 8b, and the process described above is repeated.
  • the casing 7 has been brought into the inserted position and the locking device 19 engages with the upper edge 15 of the sleeve element 8c, the compressed air is switched off.
  • a force indicated by an arrow 26 is applied to the lever arm 21, so that it rotates clockwise and the sleeve elements 8a, 8b and 8c downwards fall.
  • the locking can also be provided for all sleeve elements of the spinning positions of the entire spinning machine, with a light barrier checking whether all the sheathings 7 have been brought into the inserted position.
  • This locking device then consists, for example, of a square longitudinal member which extends along the entire machine and can be moved more or less in the horizontal direction, for example on a circular path.
  • FIG. 3 shows a variant of the casing 7 according to the invention, the sleeve elements 8a, 8b and 8c now being designed with a smaller diameter downwards.
  • the casing 7 is closed at the top with a cup-like element 27 to the machine frame 5.
  • a ring 28 which extends conically downwards and partially encompasses the underside of the bell, is arranged below the individual motor 4.
  • the suction 17 is connected to the inside of the casing 7 at the top of the cup element 27.
  • the upper edge 11 'of the sleeve elements 8a', 8b ', 8c' in this case protrudes outwards and the lower edge 12 'protrudes inwards.
  • the insertion of the casing works in the same way as before.
  • an annular opening 29 is provided in the area of the individual motor 3 of the spindle 2, so that the waste heat - represented by an arrow 30 - can be captured by the suction 17.
  • a lock is provided in a similar manner as before, which has been omitted for the sake of clarity.
  • the sleeve-like elements 8a, 8b and 8c do not merely form a circular cylinder, but can also assume other cylindrical shapes. Furthermore, it goes without saying that a light metal such as aluminum or plastic is used for the sleeve elements.
