Background technology
In weaving loom industry, in the prior art it can be found that the free end revolving cup spinning of various different embodiments
Machine.Free end revolving cup spinning machine is on the design aspect of its work station (particularly its open-end spinning device) and on described
Function or operating aspect of the open-end spinning device after spinning process interruption all may be different.Specifically, when electric power event
When the work station is restarted spinning simultaneously after barrier (wherein the spinning process at all working station of spinning machine all interrupted),
The function of known free end revolving cup spinning machine is significantly different to a certain extent.
For example, from a kind of free end revolving cup spinning machine known to the A1 of DE 101 39 075, the free end revolving cup spinning machine is matched somebody with somebody
Have so-called self-supporting work station.This means the work station of the free end revolving cup spinning machine is constructed such that their energy
It is enough automatically to restart spinning in the case of no outside help after spinning process interruption.However, equipped with this
The shortcoming of the free end revolving cup spinning machine of self-supporting work station is that their power consumption is of a relatively high, particularly during splicing
This work station needs to aspirate air.It means that the only limited quantity in the self-supporting work station after power failure
(such as ten) work station can restart spinning simultaneously, it means that because a large amount of in this free end revolving cup spinning machine
Work station, all working station of spinning machine is all restarted spinning always needs some times.Thus, in the amount of splicing
In the case of larger, these known free end revolving cup spinning machines always only have the efficiency of reduction.
In addition, for example from a kind of free end revolving cup spinning machine known to DE 199 17 968, wherein work station is by one or many
Individual operating unit is powered.So-called spinning car of advancing is arranged on the free end revolving cup spinning machine, and traveling spinning car is necessary
When provide driving to the work station that wants help, and for example spinning makes open-end spinning device restart spinning after interrupting
Yarn., it is readily seen that in this free end revolving cup spinning machine, in power failure by all works of free end revolving cup spinning machine
Make after the spinning at station all interrupts, will also need the even longer time to make free end revolving cup spin even if multiple spinning cars
Spinning at many work stations of machine restarts.This means spinned from free end revolving cup known to the A1 of DE 199 17 968
The efficiency after power failure is even lower because of time-consuming splicing for machine.
In addition, from so-called semi-automatic open-end rotor spinning machine known to the A1 of DE 10 2,005 036 485.Described half certainly
The work station of dynamic free end revolving cup spinning machine generally has the spinning apparatus for production line, line extraction device and can for producing

This means the work station of this semi-automatic open-end rotor spinning machine is constructed such that after spinning is interrupted
They can easily be reset and start spinning, without special expensive service unit.Thus, the spinning provided starts dress
The quality put is equivalent to existing quality standard.
In general, this semi-automatic open-end rotor spinning machine is relatively inexpensive weaving loom.However, described known
Semi-automatic open-end rotor spinning machine in one have the disadvantage, in power failure (wherein at all working station of weaving loom
Spinning process is all interrupted simultaneously) after, it is necessary to many work stations are singly separately provided with again in the way of time-consuming
Start spinning, thus operator must be born by the part work of each splicing.
Especially in the area that power failure frequently occurs, use utilize so-called " joint screw-in " for a long time
The free end revolving cup spinning machine of method operation.In this method (also referred to as restarting spinning in batches), free end revolving cup is spun
Yarn machine restarts the spinning of the open-end spinning device at its all working station simultaneously after power failure.For example in DE 36
The free end revolving cup spinning machine according to this long-term known splicing operation has been described in detail in 35 510 A1.
In the known free end revolving cup spinning machine, all working is disabled with prescribed manner simultaneously if power failure
Stand, and these work stations recover not in such as 2 seconds.
It means that in the free end revolving cup spinning machine operated according to " joint screw-in " method, after such as two seconds,
Controlled braking is carried out to the bobbin of operation, while determining the corresponding of the fiber collection channel of the related spinning rotary cup of the end of a thread distance
Distance, and the distance is preserved in a computer for restarting work station later.It means that turning in this free end
At all working station of cup spinning machine, in the case of spinning is interrupted, the end of a thread is always kept in the open-end spinning device of work station
Corresponding line extraction pipe region in, be that this line extraction pipe has long length.
For example from the free end revolving cup spinning machine known to the A1 of DE 36 35 510, when the electricity at all working station
When power is all recovered, work station is automatically resumed simultaneously.This means the line extraction device of work station is according to being stored in computer
In storage value ensure recover the end of a thread, and almost simultaneously restart at work station fiber supply.Limit in advance when
Between after section, the line extraction device that the line spinned again is run on pumping direction again now is extracted.
In practice, it means that, the free end revolving cup spinning machine operated according to " joint revolve people " method power failure it
Afterwards than work station singly restarts again wherein after power failure free end revolving cup spinning machine much more quickly
It is again ready for operation.However, the splicing run-of-the-mill that the spinning formed in " joint screw-in " method restarts is not high, and
