Claims
- 1. An apparatus for at least partially automatic handling of empty bobbin tubes and completely wound bobbins of a spinning machine, said apparatus comprising:
- a common apparatus frame;
- a take-over/transfer arm for empty tubes supported on said common frame;
- a take-over/transfer arm for wound bobbins, supported on said common frame;
- an actuating and swivel mechanism supported on said common frame for swivelling said empty tube take-over/transfer arm and said wound bobbin take-over/transfer arm between a service position of said empty tube take-over/transfer arm and said wound bobbin take-over/transfer arm, in which wound bobbins are slipped onto said wound bobbin take-over/transfer arm and empty tubes are slipped off said empty tube take-over/transfer arm, a transporting position in which the wound bobbin take-over/transfer arm and the empty tube take-over/transfer arm are displaced between a wound bobbin unloading and empty tube loading station and a spinning machine, and wound bobbin unloading and empty tube loading position, in which the wound bobbin is slipped off said wound bobbin take-over/transfer arm and the empty tubes are slipped onto said empty tube take-over/transfer arm;
- wherein said actuating and swivel mechanism includes swivel means for swivelling said take-over/transfer arms within a space defined by said common frame, about three spatial axes, defining respectively, the service, transporting and wound tube unloading and empty tube loading positions of said take-over/transfer arms.
- 2. The apparatus of claim 1, wherein said swivel means comprises drive means for synchronously driving said take-over/transfer arms at least within certain predetermined ranges.
- 3. The apparatus of claim 1, wherein each of said take-over/transfer arms has at a free end thereof a positioning head for compensating a misalignment between a respective take-over arm and a winding spindle.
- 4. The apparatus of claim 1, further comprising a torque rod suspension for supporting said take-over/transfer arms and said actuating and swivel mechanism on said common frame.
- 5. The apparatus of claim 4, further comprising a swivelling mechanism for supporting said torque rod suspension on said common frame.
- 6. The apparatus of claim 1, wherein said take-over/transfer arm for empty tubes and said take-over/transfer arm for wound bobbins each includes a means for slipping off and on an empty tube and a wound bobbin, respectively.
- 7. The apparatus of claim 6, wherein said take-over/transfer arm for empty tubes and said take-over/transfer arm for wound bobbins each includes a taking over and transferring means for positioning the empty tube and the wound bobbin, respectively, in at least one of an adjacent relationship and a spaced relationship; and wherein each of said take-over/transfer arm for empty tubes and said take-over/transfer arm for wound bobbins includes a retaining brake for a tube and a bobbin, respectively, whereby the tube and the bobbin cannot be slipped off.
- 8. The apparatus of claim 6, wherein said slipping off and on means includes linear drive means for effecting slip off and on movement of the empty tube and the wound bobbin.
- 9. The apparatus of claim 1, wherein said frame includes an undercarriage and an all-wheel steering means for driving said undercarriage.
- 10. The apparatus of claim 1, wherein said actuating and swivel mechanism includes at least one of hysteresis coupling means, magnetic coupling means, and magnetic brake means.
- 11. The apparatus of claim 1, wherein each of said take-over/transfer arms includes cam means for centering an empty tube and a wound bobbin, respectively, on a respective take-over/transfer arm.
