Device for the mass spinning-in of spinning units in spindleless spinning machines

Claim 2

A spindleless spinning machine comprising electrically operable fiber feed, a spinning chamber and yarn withdrawing mechanisms, a primary source of electric power, circuit control means connecting said source of power to said mechanisms for synchronizingly operating said mechanisms, auxiliary power generating means independent of said primary source, said auxiliary power generating means being mechanically connected to the operable mechanisms for producing an independent electric current source and means connecting said independent source to said circuit control system to provide power in the absence of the primary power source.

Claim 3

The machine according to claim 1 wherein said spinning chamber is fixedly mounted on a rotatable shaft and said generator means includes a rotor operatively connected to said shaft to be rotatable therewith.

Claim 4

The machine according to claim 2 wherein said generator means comprises a DC generator.

Claim 5

The machine according to claim 2 wherein said generator means comprises an alternator having rectifying means.

Claim 6

The machine according to claim 1 wherein said control means for synchronously operating said feed and spinning mechanism respectively includes means for stopping said feed before stopping said spinning mechanism.

Claim 7

The machine according to claim 1 including: an electric motor; a rotatable spinning chamber for converting discrete fibers into yarn; a rotatable feed mechanism for feeding fibers to said chamber; a rotatable withdrawing mechanism for withdrawing yarn; a rotatable winding mechanism for winding said yarn on a bobbin; first connecting means linking said motor to said spinning chamber for rotating the same; second connecting means for linking said motor to said feed mechanism for rotating the same including, electrically operable first clutch means, interposed therebetween; third connecting means for linking said motor to said withdrawing mechanism for rotating the same including an electrically operable second and third clutch means interposed therebetween, said second and third clutches being selectively operable to effect reversible operation of said withdrawing means, in forward and reverse directions; fourth connecting means linking said motor to said winding mechanism for rotating the same including a fourth clutch interposed therebetween; first control system having means for selectively directing said current to said interposed clutches in predetermined order to sequentially obtain reverse operation of said withdrawing mechanism prior to operation of said feed, withdrawing and winding mechanisms on starting of said machine and subsequent forward operation on stopping of said machine.

Claim 8

The machine according to claim 6 includiNg a second control system having means for selectively directing said current to said interposed clutches in predetermined order, said second system being responsive to the operation of said first system for a predetermined length of time to thereafter effect the feeding of fibers of yarn in the forward direction.

Claim 9

The machine according to claim 7 wherein said feed mechanisms includes a fiber separator and means for independently driving the same.

Claim 10

The machine according to claim 7 including means for sensing the tension on the withdrawn yarn and for deactivating said first control system when said tension falls below a predetermined level.

Claim 11

The machine according to claim 9 wherein said sensing means is connected to a fifth clutch interposed between said feed mechanism and said motor, said fifth clutch being deactivated when the tension in said yarn falls below said predetermined level.

Claim 12

The machine according to claim 7 wherein said second control system includes a mechanical linkage with said first control system comprising a solenoid, operated by said first control system, a detent mechanism, comprising a gear train between said spinning chamber and a releasably locking ratchet and pawl device, said gear train being operable to lock said ratchet and pawl in response to activation of said solenoid and release said ratchet and pawl on deactivation thereof, a connecting rod linking said ratchet and pawl to said second control system, said rod being adapted to operate said second control system in response to said ratchet and pawl.

Claim 13

The machine according to claim 11 wherein said detent mechanism is adjustable.

Claim 14

The machine according to claim 10 including an electrically operated relay having a normally closed contact connecting the electric source to said solenoid.
