Description
Technical field
Object of the invention is a kind of according to the present invention for controlling the method and spinning to yarn of at least one furnisher
Loom.In particular, the present invention relates to by with memory bank furnisher (that is this passes through memory-furnisher) to
Yarn, wherein yarn is drawn out accordingly by weaving loom from memory bank.
Background technique
Here, yarn tension is adjusted to the reference value of yarn tension by brake apparatus and by yarn tension unit
On.In the case where adjusting yarn tension, the measured value of yarn tension is measured by yarn tension measuring unit and is correspondingly existed
Difference between measured value and reference value is minimized.In yarn tension measuring unit (also referred to as yarn tension sensor)
For example since heating generates zero shifting in operation.It is thereby necessary that periodically determining the zero point of yarn tension sensor.
The zero point of sensor is determined in the case where lifting yarn as known to 704303 B1 of file CH.
For sensor used in the case where furnisher of the yarn tension through adjusting, in the feelings for erectting yarn
The compensation of sensor is realized in condition (that is zero point determines for this).
In 0 943 713 B1 of file EP, such as illustrate a kind of yarn lifting repeatedly by sensor.By file
2,007 22 69 A of ITMI00 becomes known for determining the rotation forward to yarn wheel of the furnisher of zero point.
It is illustrated in 195 00 517 A1 of file DE, sensor is calibrated in the case where the yarn erect and moved
And correction.
Yarn tension sensor also be used to roll and rewinding.It is known that and is being wound by 0 406 735 B1 of file EP
The measured value of sensor is acquired in the case where each interruption of process and is used as new zero point.
It is problematic when determining zero point in the case where erectting yarn, it needs to determine, sensor no longer passes through yarn and added
It carries.
The problem mentions solution by yarn for example in above-mentioned 0 943 713 B1 of file EP repeatedly.For this purpose, single
Only additional unit that lifts is necessary.
Because yarn tension sensor is used to adjust for the yarn for the yarn being drawn out by memory-furnisher in the present invention
Line tension, so rotating forward as known to above-mentioned 2,007 22 69 A of ITMI00 for furnisher cannot be used.
Summary of the invention
The object of the present invention is to develop a kind of yarn for memory-furnisher yarn tension is adjusted to yarn
The determination of the zero point of line tension measuring unit.

In example, the duration of operation corresponds to furnisher 1,1', and the yarn of the determination of at least one of 1'' ... being provided is long
Degree Lb is consistent.And then, central control unit FS stops weaving loom M.
In fourth stage, central control unit FS starts for furnisher 1,1', and the braking of 1'' ... unloads, via arriving
The signal S1 for being used to brake unloading at corresponding determination unit 70.Braking unloading BE is in furnisher 1,1', 1'' ... as opposite
It is executed as Fig. 3 is illustrated.Central control unit FS inquires furnisher 1,1', and 1'' ... braking unloading BE and zero point are really
It is fixed whether to terminate.
When this is for all furnishers 1,1', when 1'' ... is such case, yarn tension theoretical value Fsoll passes through center
Control device FS by return sets to furnisher 1,1', 1'' ... the stored yarn tension theoretical value Fi of beginning on.
Fig. 5 shows that the available machine time of weaving loom M, brake signal (are that is used for the determination unit 70 of operating current
Output valve I_SOLL) and the yarn tension during the zero point for the tonometry unit for determining furnisher 1 curve diagram.
This illustration shows weaving loom M is adjusted (beginning) and continues in determining operation after short period of time
(stopping) being closed after time.The duration of operation is corresponding to the determining length of yarn Lb supplied.
The moment is started in weaving loom M, the output valve Ib of operating current is passed to from actuating coil 12 from determination unit 70,
Its yarn tension operating parameter Fb for corresponding to central control unit FS.Yarn tension is conditioned.Here, the slight wave of output valve Ib
It is dynamic.
Yarn tension declines after shutting down weaving loom M.Output valve Ib is maintained on value Ib, until starting braking unloading
BE.Yarn tension drops in the value on its zero point.
After braking unloading BE starts, output valve is changed on output valve Ia during postponing Ta.
Output valve Ia is in the total size of operating current (that is brake signal), in maximum value Imax and minimum value
Average value between Imin.In one example, the total size of operating current is 200mA to -200mA, wherein output valve Ia is
0mA and minimum value Imin are -200mA.
It realizes that the unloading that quantity is N recycles, wherein N is 3.During unloading circulation, output valve passes through determination unit 70
It is changed on value Imin with ladder Δ I by output valve Ia and is changed on initial value Ia again.It is waited between unloading circulation
Interval Tp.
During unloading circulation, especially during the first unloading circulation, yarn tension drops under its zero point.Last
That is third unloading circulation output valve Imin in the case where, the new zero point of tonometry unit is determined.This
That is the deviation m0 of measuring device 51 is changed as described above.
In an alternative, central control unit FS is connected only for transmission stop signal with weaving loom M.It is weaving
The control executed in the example previous of machine M by central control unit FS is implemented manually by operator.
