Definitions

  • the invention relates to a drafting system for a spinning machine according to the preamble of claim 1.
  • Draw frames in various embodiments are known in connection with spinning machines, for example with ring spinning machines or with air-jet spinning machines.
  • the drafting systems differ, for example, in terms of the number of pairs of rollers, with respect to the structural design of their pendulum carrier or in terms of the formation of their lower rollers in some cases considerably.
  • machine-length lower rollers are usually driven by a strong, machine end side arranged in the drive frame of the textile machine drafting motor, which ensures via an intermediate reduction gear that the input, middle, and output lower rollers rotate at different speeds and forgive the submitted sliver.
  • a ring spinning machine which in each case has a plurality of relatively short, single-motor driven lower roller sections instead of machine-length lower rollers, which form the draw frames in conjunction with corresponding upper rollers.
  • the lower roller sections are designed as external rotor drives. That is, between two cheeks of the machine frame of the ring spinning machine, a bearing shaft is fixed in rotation, which carries the stator of the external rotor drive.
  • the electric rotor of the drive is arranged within a rotatable hollow roller, which is also supported via corresponding bearing points on the bearing axis.
  • On the hollow roller which in each case forms a lower roller section for a plurality of juxtaposed spinning station drafting systems, are the associated upper rollers, which are taken along frictionally engaged by the lower roller section during the spinning operation.
  • Draw frames for spinning machines are also by the DE 39 32 614 A1 known.
  • the individual drives of the lower roller segments are connected to a control device which can adjust the speed of the drives and thus the delay of the drafting system via a corresponding inverter.
  • the lower roller segments are either directly connected to one of the drives via a motor shaft or in each case connected via a drive belt to one of the drives.
  • the invention has for its object to provide a drafting system, designed as a roller segments lower rollers in case of need, especially for changing the delay straps, are easily accessible or easily removable.
  • the drafting system according to the invention has the particular advantage that after opening the pendulum carrier, the lower roller drives including the associated roller segments can be easily removed immediately in the direction of the pendulum carrier from their storage facilities, which have upwardly open receptacles. That is, for removal or installation of the motor driven sub-roller segments no tools or the like is needed.
  • Verzugsriemchen which are preferably arranged in the region of the lower roller segments of the middle lower roller, freely accessible and can be changed quickly and easily if necessary.
  • the storage facilities for the lower roller drives have receiving pockets and, for example, by means of bolts to a frame can be fixed, which in turn is attached to the machine frame of the air-spinning machine (claims 2). That is, during the spinning operation, the lower roller drives and thus the associated lower roller segments are exactly aligned, in their working positions and are thereby fixed by the closed pendulum carrier securely in the receiving pockets of the storage facilities. By opening the shuttle carrier, the lower roller drives are released and, together with their associated lower roller segments, can be easily lifted out of the storage facilities. The installation of the lower roller segments is just as easy.
  • the bottom roller drives are simply inserted from above into the open storage facilities and are immediately aligned correctly.
  • the inner dimensions of the receiving pockets of the storage facilities are matched to the outer contours of the lower roller drives.
  • the lower roller drives and thus the lower roller segments both safely with the pendulum carrier and during the spinning process, when the pendulum carrier is closed, safely and reliably positioned.
  • At least the middle lower roller is formed in several parts. That is, at least the middle lower roller consist of two lower roller segments, which in turn are non-rotatably connected to a lower roller drive and rotatable relative to each other. In this way, on the one hand, it is ensured that, if necessary, the middle bottom roller can be divided without any problem can be used to easily change the override aprons.
  • the relative movement of the lower roller segments to each other also allows a separate drive of the two drafting equipment sides. That is, in a yarn breakage, in which one side of the drafting system is stopped, the other side of the drafting system can remain in operation.
  • the drives of the lower roller segments of the input sub-roller and the drives of Under roller segments of the middle lower roller formed as stepper motors (claims 5).
  • stepper motors represent proven and cost-effective mass-produced components, which are also relatively easy to control, for example, also in terms of their speed. That is, via a corresponding, relatively simple control device, the desired delay of the drafting system can be accurately adjusted via the speeds of the input sub-roller and the center lower roller and corrected if necessary without much effort.
  • the lower roller segments each have a bearing stump in the region of their free end, which protrudes in the installed state of the lower roller segments in a bearing sleeve.
  • the bearing sleeve is equipped with rolling bearings on which the bearing stumps are supported.
  • Fig. 1 the drafting device 4 according to the invention is shown schematically in connection with an air-spinning machine 1.
  • Such textile machines generally have a plurality of workstations 2 arranged in series next to one another and at least one end of the air-spinning machine 1, a so-called end frame 13.
  • each of the working or spinning stations 2 of such an air-spinning machine 1 has a sliver source, for example a sliver can 3, a drafting device 4, an air-spinning device 5, a yarn withdrawal device 6, a yarn cleaner 7 and a thread-changing device 8.
  • the Fadenchangier listening 8 ensures that the manufactured in the air spinning device 5 thread is wound in intersecting layers on a package 9.
  • the cheese 9 is, as usual, held in a (not shown) creel and is rotated by a (also not shown) coil drive.
  • the spinning units 2 of the air-spinning machine 1 are supplied by an automatically operating operating rotor 10, which, guided on rails 11, 12, is movable along the spinning stations 2.
  • the drafting units 4 usually, an input roller pair 20, a pair of intermediate rollers 21 and a pair of output rollers 23, wherein the pairs of rollers each of drivable bottom rollers 20A, 21A, 23A and 20 held in a pendulum carrier top rollers 20B, 21B, 23B consist.
  • the pendulum support 17 is limited movably mounted on a support rod 30 and can by means of a lever 29 in three possible positions a) "loaded", b) "relieved” and c) "folded” positioned.
  • the lower rollers 20A, 21A, 23A in turn each consist of lower roller segments 20A1, 20Ar; 21A1, 21Ar; 23A1, 23Ar together, which can be rotated by a lower roller drive 14 and 28, respectively.
  • the lower roller segments 20Al, 20Ar; 21Al, 2lAr; 23Al, 23Ar are rotatably connected to the motor shafts of the lower roller drives 14 and 28, which in turn are connected via supply and signal lines 22 to a power source, not shown, and also not shown control device.
  • the lower roller segments 20A1, 20Ar; 21A1, 21Ar; 23A1, 23Ar each have a bearing stub 25 in addition to a structured working surface 16 in the region of its free end.
  • these bearing stubs 25 are guided in bearing sleeves 24, which have roller bearings 26, preferably needle roller bearings.
  • delay straps 27 are also arranged which, as usual, are guided on deflection rails 31.
  • the lower roller drives 14 and 28 are easily interchangeable arranged in storage facilities 15, the screw bolts 32 at a frame 18 are fixed, which in turn is attached to the machine frame of the air-spinning machine 1.
  • the open receptacles 19 of the storage facilities 15 are so designed with respect to their inner dimensions on the contour of the lower roller drives 14, 28 that the lower roller drives 14, 28 immediately after positioning in the storage facilities 15 are exactly in their working position and can be fixed by closing the pendulum carrier 17 ,
