Background technology
Generally, the wefting insertion of water jet loom is set according to cooperation from the injection opportunity of the press water of Weft insertion nozzle injection
, locking releasing opportunity of locking pin and opening opportunity of clamper start.It should be noted that injection opportunity be by with
The opportunity for the fixation that synchronously driven cam mechanism of main shaft of water jet loom etc. is mechanically set.
Specifically, in water jet loom, start to spray pressure from Weft insertion nozzle first with the injection opportunity of setting
Water.Wherein, on the opportunity started in the injection of press water, parallel is leaning on upstream side compared with Weft insertion nozzle, by parallel storage facility
Stopped by engaging pin card, and held by clamper, therefore do not proceeded by and walk.Then, after the injection of press water starts,
The locking for the parallel that locking pin is carried out is released from, next, opening holding of the clamper to parallel, thus starts walking for parallel
(wefting insertion).It should be noted that the parallel of locking pin progress is released on locking releasing opportunity, the opening opportunity of above-mentioned setting
Locking and the holding for opening the parallel that clamper is carried out.
However, in such water jet loom, wire body is confessed when configuring in the upstream side of parallel storage facility
Parallel pull-out resistance, from the unwinding resistance of the unwinding parallel of parallel storage facility because carrying out associated above-mentioned confession with woven
The reduction of the coil diameter of wire body and when changing, parallel walks difficulty, in other words the traverse speed change of parallel, therefore parallel
Front end reach opportunity (reach in opportunity) change (not fixing) for the opposite side of line.
Thus, for example, in the case where the opportunity of arrival shifts to an earlier date, along with the end of wefting insertion in the latitude carried out using press water
The leading section of parallel is elongated during turning into unconstrained state when the carrying capacity of line disappears, therefore so-called inflection phenomenon occurs,
The quality problems such as parallel relaxation are produced in the edge of woven fabric.

Patent document 1：Japanese Unexamined Patent Application 62-117853 publications
However, not publicly possessing in above-mentioned patent document 1 has clamper, and as above-mentioned premise device of the invention that
Sample, in general water jet loom are also equipped with compared with Weft insertion nozzle by the work of upstream side configuration in addition to above-mentioned locking pin
For the clamper of wefting insertion control member.Moreover, for such water jet loom, particularly, understood as described above
Except the holding to opening the parallel that clamper is carried out after the action of the locking of parallel is sold in locking, thus start the water walked of parallel
Jet weaving machine, in the case of in controlling the wefting insertion of above-mentioned patent document 1 for above-mentioned water jet loom, it is controlled
Object turns into the clamper in locking pin and clamper as wefting insertion control member, and the opening opportunity of the clamper is carried out
Control.
It should be noted that in water jet loom, in general, due to without in the parallel for the opposite side of line
The detection on arrival opportunity (opportunity that the assigned position for the opposite side of line is reached by the front end of the parallel of wefting insertion), therefore, sprays in water
In the case of penetrating in formula loom the control for carrying out wefting insertion control member as described above, using following unwinding opportunity, this is unwinding
Opportunity is detected according to the signal from the unwinding sensor for being attached to parallel storage facility.Moreover, the unwinding opportunity
Detected according to following signal, the signal from parallel storage facility along with wefting insertion by storing the unwinding latitude of drum
Line exports by the position (unwinding sensor detects to parallel) of unwinding sensor from unwinding sensor.
Also, in the control of above-mentioned wefting insertion control member (clamper), to unwinding opportunity of the parallel detected and
Compared with a reference value related with the unwinding opportunity, according to its deviation come the opening opportunity for the clamper that makes corrections.For example, on this
Control, when assuming that the traverse speed of parallel is fixed speed, detected in the case where said reference value is 200 ° unwinding
In the case that the detected value on opportunity is 202 °, carry out as follows, i.e. according to 2 ° of the deviation, enter to be about to beating for clamper
The setting value for opening opportunity shifts to an earlier date 2 ° of correction, thus makes unwinding opportunity consistent with said reference value.
In addition, in general loom, the encoder that is used to detect the anglec of rotation of main shaft (degree in crank angle)
Resolution ratio is that 180 pulses/mono- encloses (0 °~360 °) Zuo You, whenever main shaft rotates the output hair of 2 ° of pulse signals for carrying out self-encoding encoder
Changing.Moreover, in loom, degree in crank angle is detected by the output of the pulse signal from the encoder, in addition, being in
The above-mentioned degree in crank angle on the opportunity that each sensor detects turns into the detection opportunity (for example, above-mentioned unwinding opportunity) of the sensor.
Therefore, above-mentioned unwinding opportunity is detected as detected value of the degree in crank angle for 2 ° of units.
Therefore, even if being 201 ° when the degree in crank angle on the opportunity of unwinding sensor detection parallel is actual, as noted previously, as
Output by the pulse signal for carrying out self-encoding encoder the degree in crank angle that detects is 2 ° of units, therefore the detected value on unwinding opportunity
Not 201 °, and it is also 202 °.Its result is as described above, on the control on the opening opportunity of clamper, to enter to be about to its dozen
The setting value for opening opportunity shifts to an earlier date 2 ° of correction.But in this case, actual unwinding opportunity is 201 ° as described above, real
The deviation on border is 1 °, therefore has carried out excessive correction.
Moreover, the result of above-mentioned correction is, the actual opportunity of unwinding sensor detection parallel is 199 °, but detected value
For 200 °, be judged as it is consistent with said reference value, even if therefore the deviation on unwinding opportunity actually occurs, also regard as not producing
Deviation and continue to weave.Its result is not carry out appropriate wefting insertion, and the quality of fabric occurs and reduces the problem of such.
It should be noted that in order to eliminate the problem of such, considering to use has high-resolution encoder, but like that
Encoder costly, therefore cause the cost of device to improve.
The content of the invention
The invention that the present invention completes for the above-mentioned actual conditions of consideration, its object is to, there is provided one kind is foregoing
It can realize that the wefting insertion of the appropriate control of wefting insertion control member controls in water jet loom without using the encoder of costliness.
【For solving the scheme of problem】
The present invention is applied in following water jet loom, and the water jet loom possesses：Parallel storage facility, it is logical
Locking pin card is crossed to stop parallel and parallel is stored on storage drum, and according to the setting on locking releasing opportunity set in advance
Value releases locking of the locking pin to parallel；Unwinding sensor, it is released from the locking of the locking pin to parallel
In the state of when carrying out wefting insertion, to being detected from unwinding parallel on the storage drum；And clamper, it, which is arranged on, draws
Between weft inserting nozzle and the parallel storage facility and parallel is held, and is opened according to the setting value on opening opportunity set in advance
The holding to parallel.
Moreover, the wefting insertion control method of the present invention is characterised by, in the water jet loom, institute is come to basis
The detected value on the unwinding opportunity stated the signal of unwinding sensor and detected and set in advance related to the unwinding opportunity
A reference value is compared to solve deviation, and according to the correction model of weave cycle unit set in advance, using based on institute
State the correction amount calculated by deviation, the correction on alternately described locking releasing opportunity and the opening opportunity.
In addition, for realizing that the Weft insertion controller of the invention of above-mentioned wefting insertion control method is characterised by, described
In water jet loom, possess：Comparator, its to detected according to the signal from the unwinding sensor output it is unwinding when
The a reference value of the detected value of machine and set in advance and described unwinding opportunity correlation is compared and solves deviation；And opportunity mends
Positive device, it solves the correction on the locking releasing opportunity and the opening opportunity according to the deviation obtained by the comparator
Amount, and being maked corrections using the correction amount locking releasing opportunity and the opening opportunity, the opportunity retriever according to
The benefit on the correction model of weave cycle unit set in advance, alternately described locking releasing opportunity and the opening opportunity
Just.
It should be noted that above-mentioned " weave cycle " turn around equivalent to the main shaft in the continuously running of loom (0 °~
360°).That is, a series of weaving action (wefting insertion~beating) is carried out once during main shaft turns around, therefore main shaft turns around
During turn into a weave cycle.Moreover, mutually with the woven progress continuously run to realize by loom, therefore exist
The situation of " step " will be referred to as in " cycle ".
【Invention effect】
According to the present invention, due to the excessive correction for actual reelability opportunity can be suppressed, therefore without using the volume of costliness
Code device just can realize appropriate wefting insertion control.Detailed content is as described below.
First, on condition that, the water jet loom that the present invention applies is to carry out the press water from Weft insertion nozzle
Released after injection using locking of the locking pin to parallel, after this, open the loom using holding of the clamper to parallel.And
And in this water jet loom, in the case where having carried out the correction (change) on locking releasing opportunity of locking pin, with entering
Compared before row correction, the parallel between the opportunity of the holding to parallel, storage drum and clamper is opened in clamper
Relaxation degree it is different, therefore, the unwinding resistance of the parallel of the storage drum in wefting insertion initial stage can change.That is, as described above
Locking of the pin to parallel is engaged like that to release prior to opening in the water jet loom of the holding of parallel using clamper, with
The locking of locking pin releases, and parallel turns into the state of relaxation between storage drum and clamper, therefore at the beginning of above-mentioned wefting insertion
Phase, first, the relaxation of the parallel is eliminated, afterwards as parallel from storage drum unwinding carries out wefting insertion.
Therefore, during the relaxation of the above-mentioned parallel in above-mentioned wefting insertion initial stage is eliminated, parallel is not accompanied by from storage
Drum carries out wefting insertion unwindingly.Moreover, because the locking of change locking pin releases opportunity so that the relaxation degree of above-mentioned parallel becomes
Change, thus be not accompanied by parallel from store drum it is unwinding during change.Thus, the traverse speed of the parallel at wefting insertion initial stage occurs
Change, the result is that the average traverse speed of the parallel in during wefting insertion changes, therefore the detection on the unwinding opportunity of parallel
Value changes.Like this, in above-mentioned water jet loom, the correction control parallel on the opening opportunity of clamper is walked out
Opportunity beginning, the correction to the locking releasing opportunity of this locking pin control the average traverse speed of parallel.
It should be noted that in above-mentioned water jet loom, only the opening opportunity of clamper is maked corrections, parallel
Traverse speed substantially will not also change, therefore the correction amount on the opening opportunity (the walking beginning opportunity of parallel) of clamper is direct
It is presented as the change of the detected value on unwinding opportunity.That is, for example, as described above for the opening opportunity of clamper, when 2 ° in advance
Degree in crank angle when, the detected value on unwinding opportunity shifts to an earlier date 2 °.On the other hand, do not change clamper opening opportunity (parallel
Walk beginning opportunity) and the locking only to locking pin is released in the case that opportunity makes corrections, only wefting insertion initial stage as described above
The traverse speed of parallel change, therefore the detected value on unwinding opportunity is smaller relative to the change of its correction amount.That is, for
The locking of locking pin releases opportunity, even if the degree in crank angle of 2 ° of correction, the change of the detected value on unwinding opportunity is also smaller than 2 ° very
More values.
Therefore, in the case of producing deviation between the detected value on unwinding opportunity and said reference value, if correction locking
The locking of pin releases opportunity, and above-mentioned【Background technology】The situation on the opening opportunity of described correction clamper is compared, will not
Carry out excessive correction.Wherein, on locking pin locking releasing opportunity correction, due to unwinding opportunity variable quantity relative to
, it is necessary to take time to eliminate the deviation in the case that its correction amount is smaller, therefore above-mentioned deviation is big, appropriate draw can not be carried out therebetween
The state of latitude continues, therefore the quality with fabric reduces.
On the other hand, according to the present invention, by alternately being engaged according to the correction model of weave cycle unit set in advance
Pin locking releasing opportunity correction and clamper opening opportunity correction, thus, without as prior art repeatedly
Excessive correction is carried out, and can promptly carry out the elimination of deviation, therefore can also be realized without using the encoder of costliness
Appropriate wefting insertion control.
