Description
Technical field
The utility model relates to a kind of Weft insertion controller using water jet loom as prerequisite device, this water jet loom possesses: parallel storage facility, it stops parallel by locking pin card and is stored in by parallel on storage drum, and removes the locking of the described locking pin of setting value releasing to parallel on opportunity according to the locking preset; Unwinding sensor, it, when described locking pin is carried out wefting insertion to the described locking of parallel under the state removed, detects from unwinding parallel on described storage drum; And clamper, it to be arranged between Weft insertion nozzle and described parallel storage facility and to hold parallel, and opens the described holding to parallel according to the setting value on the opportunity of opening preset.
Background technology
Usually, the wefting insertion of water jet loom according to coordinating the injection of the press water sprayed from Weft insertion nozzle to set opportunity, engage the locking releasing opportunity of pin and clamper open opportunity.It should be noted that, injection is the fixing opportunity that the cam mechanism etc. by driving with the spindle synchronous of water jet loom mechanically sets opportunity.
Specifically, in water jet loom, first to start from Weft insertion nozzle expulsion pressure water opportunity with the injection of setting.Wherein, on the opportunity of the injection beginning of press water, parallel compared with Weft insertion nozzle by upstream side, by parallel storage facility by locking pin card only, and held by clamper, therefore do not start to walk.Then, after the injection beginning of press water, the locking that the parallel carried out is sold in locking is removed, and next, opens the holding of clamper to parallel, starts walking (wefting insertion) of parallel thus.It should be noted that, remove in the locking of above-mentioned setting and opportunity, the opportunity of opening remove the locking of the parallel that this locking pin carries out and open the holding of the parallel that clamper carries out.
But, in such water jet loom, when be configured in parallel storage facility upstream side the pull-out resistance confessing the parallel of line body, from the unwinding resistance of the unwinding parallel of parallel storage facility because of with woven carry out together above-mentioned change for the minimizing of the coil diameter of line body time, parallel walk difficulty, in other words the traverse speed change of parallel, therefore the front end of parallel arrives opportunity (the arriving opportunity) change (not fixing) for line opposition side.
Therefore, such as, when arrival shifts to an earlier date opportunity, along with wefting insertion end the parallel utilizing press water to carry out carrying capacity disappear time parallel leading section become unconstrained state during elongated, therefore there is so-called inflection phenomenon, produce the quality problems such as parallel is lax in the edge of woven fabric.
As the prior art making arrival opportunity fixing for solving the above problems, there is the following content disclosed in patent document 1.More particularly, this patent document 1 discloses the Weft insertion controller of following loom, it possesses: parallel storage facility, its upstream side being close to the direct of travel of parallel compared with the nozzle (Weft insertion nozzle) of wefting insertion configures, stop parallel by utilizing the locking pin card as wefting insertion control member parallel is stored on drum (storage drum), and remove the locking of locking pin to parallel according to the setting value on the retrogressing opportunity preset (locking releasing opportunity); Sensor (unwinding sensor), its above-mentioned locking of parallel utilizing locking to sell to carry out by carry out under the state removed wefting insertion time, detect from unwinding parallel on storage drum.
And, in the Weft insertion controller of this patent document 1, the parallel that unwinding sensor detects wefting insertion arrive the position of regulation, opportunity when namely parallel is unwinding with the length of regulation, and the arrival of the arrival opportunity detect it and standard compares opportunity, the action upgrading wefting insertion control member (mainly engaging pin) according to this comparative result starts opportunity (locking releasing opportunity).
At first technical literature
Patent document
Patent document 1: Japanese Laid-Open Patent Publication 62-117853 publication
But, unexposedly in above-mentioned patent document 1 have clamper, and as above-mentioned prerequisite device of the present utility model, general water jet loom, except above-mentioned locking pin, also possesses the clamper as wefting insertion control member by upstream side configuration compared with Weft insertion nozzle.And, for such water jet loom, particularly, the holding of the parallel that clamper carries out is opened as mentioned above after having carried out removing the action of locking pin to the locking of parallel, start the water jet loom of walking of parallel thus, when being controlled to be used in above-mentioned water jet loom by the wefting insertion of above-mentioned patent document 1, its control object becomes as the clamper in the locking pin of wefting insertion control member and clamper, controls the opportunity of opening of this clamper.
It should be noted that, in water jet loom, in general, owing to not carrying out the detection on the arrival opportunity (being arrived the opportunity of the assigned position for line opposition side by the front end of the parallel of wefting insertion) at the parallel for line opposition side, therefore, when carrying out the control of wefting insertion control member as above in water jet loom, use following unwinding opportunity, this unwinding opportunity detects according to the signal from the unwinding sensor being attached to parallel storage facility.And, this unwinding opportunity detects according to following signal, and this signal is by exporting from unwinding sensor through the position (unwinding sensor detects parallel) of unwinding sensor from the parallel that the storage drum of parallel storage facility is unwinding along with wefting insertion.
Further, in the control of above-mentioned wefting insertion control member (clamper), compare unwinding opportunity of the parallel that this detects and a reference value relevant to this unwinding opportunity, that carrys out correction clamper according to its deviation opens opportunity.Such as, about this control, when the traverse speed supposing parallel is fixed speed, when the detected value on the unwinding opportunity detected when said reference value is 200 ° is 202 °, carry out as follows, that is, according to this deviation of 2 °, carry out the correction setting value on the opportunity of opening of clamper being shifted to an earlier date 2 °, make unwinding opportunity consistent with said reference value thus.
In addition, in general loom, in order to detect the anglec of rotation (degree in crank angle) of main shaft, the resolution ratio of encoder that uses is that 180 pulse/mono-enclose (0 ° ~ 360 °) left and right, changes whenever main shaft rotates 2 ° of outputs from the pulse signal of encoder.And in loom, detect degree in crank angle by the output of the pulse signal from this encoder, in addition, the above-mentioned degree in crank angle being in the opportunity that each sensor detects becomes the detection opportunity of this sensor (such as, above-mentioned unwinding opportunity).Therefore, be detected as the detected value that degree in crank angle is 2 ° of units above-mentioned unwinding opportunity.
Therefore, even if the degree in crank angle of working as the opportunity of unwinding sensor detection parallel is actual is 201 °, as mentioned above, because the degree in crank angle detected by the output from the pulse signal of encoder is 2 ° of units, therefore the detected value on unwinding opportunity is not 201 °, and is 202 ° yet.Its result is, as described above, about the control on the opportunity of opening of clamper, the setting value of carrying out the opportunity that opens it shifts to an earlier date the correction of 2 °.But in this case, unwinding opportunity actual is as described above 201 °, and actual deviation is 1 °, because this has been excessive correction.
And the result of above-mentioned correction is, the opportunity that unwinding sensor detects the reality of parallel is 199 °, but detected value is 200 °, be judged as consistent with said reference value, even if therefore in fact there is the deviation on unwinding opportunity, also regard as and do not produce deviation and continue to weave.Its result is, does not carry out suitable wefting insertion, and the quality that fabric occurs reduces such problem.
It should be noted that, in order to eliminate such problem, consider that use has high-resolution encoder, but such encoder costly, therefore causes the cost of device to improve.
Utility model content
The utility model is consider the utility model that completes of above-mentioned actual conditions, its object is to, and provides a kind of and in foregoing water jet loom, does not use expensive encoder and the wefting insertion that can realize the suitable control of wefting insertion control member controls.
[for solving the scheme of problem]
The utility model is applied in following water jet loom, the Weft insertion controller of water jet loom, possess: parallel storage facility, it stops parallel by locking pin card and is stored in by parallel on storage drum, and removes the locking of the described locking pin of setting value releasing to parallel on opportunity according to the locking preset; Unwinding sensor, it, when described locking pin is carried out wefting insertion to the described locking of parallel under the state removed, detects from unwinding parallel on described storage drum; And clamper, it to be arranged between Weft insertion nozzle and described parallel storage facility and to hold parallel, and opens the described holding to parallel according to the setting value on the opportunity of opening preset.
In addition, the feature of Weft insertion controller of the present utility model is, possess: comparator, it compares with a reference value relevant to described unwinding opportunity preset the detected value on the unwinding opportunity detected according to the signal exported from described unwinding sensor and solves deviation; And opportunity retriever, it is according to the deviation obtained by described comparator, solve described locking releasing opportunity and described in open the correction amount on opportunity, and utilize this correction amount come to engage described in correction releasing opportunity and described in open opportunity, described opportunity, retriever was according to the correction model of the weave cycle unit preset, hocket described locking releasing opportunity and described in open the correction on opportunity.
It should be noted that, above-mentioned " weave cycle " main shaft be equivalent in the continuous running of loom turns around (0 ° ~ 360 °).That is, carry out once a series ofly weaving action (wefting insertion ~ beat up) in main shaft period of turning around, therefore main shaft becomes a weave cycle during turning around.And what realize with the continuous running by loom wovenly carries out, and therefore there is the situation " cycle " being called " step ".
[utility model effect]
According to the utility model, due to the excessive correction for actual reelability opportunity can be suppressed, therefore do not use expensive encoder just can realize suitable wefting insertion and control.Detailed content is as described below.
First, prerequisite is, the water jet loom of the utility model application is carrying out removing afterwards from the injection of the press water of Weft insertion nozzle utilizing the locking of locking pin to parallel, after this, opening the loom of the holding utilizing clamper to parallel.And, in this water jet loom, when correction (change) on opportunity is removed in the locking having carried out engaging pin, compared with before carrying out correction, be in clamper open the opportunity of the holding to parallel, storage drum different from the relax level of the parallel between clamper, therefore, the unwinding resistance being in the parallel of the storage drum at wefting insertion initial stage can change.Namely, remove in the water jet loom prior to utilizing clamper to open the holding of parallel to the locking of parallel engaging pin as described above, along with the locking of locking pin is removed, parallel becomes lax state between storage drum and clamper, therefore at the above-mentioned wefting insertion initial stage, first, eliminate the lax of this parallel, afterwards along with parallel carries out wefting insertion from the unwinding of storage drum.
Therefore, during above-mentioned parallel lax being in the above-mentioned wefting insertion initial stage is eliminated, do not carry out wefting insertion with parallel from the unwinding of storage drum.And, because of change locking pin locking remove opportunity, the relax level of above-mentioned parallel change, therefore not with parallel from storage drum unwinding during change.Thus, the traverse speed of the parallel at wefting insertion initial stage changes, and the average traverse speed of the parallel in consequently during wefting insertion changes, and therefore the detected value on the unwinding opportunity of parallel changes.Like this, in above-mentioned water jet loom, the correction on the opportunity of opening of clamper controls the beginning opportunity of walking of parallel, and the correction removing opportunity to locking of this locking pin controls the average traverse speed of parallel.
It should be noted that, in above-mentioned water jet loom, only to carrying out correction the opportunity of opening of clamper, the traverse speed of parallel also can not change substantially, and therefore the correction amount of the opening opportunity of clamper (parallel walk beginning opportunity) is directly presented as the change of the detected value on unwinding opportunity.That is, such as, open opportunity as described above for clamper, when the degree in crank angle of 2 ° in advance, the detected value on unwinding opportunity shifts to an earlier date 2 °.On the other hand, when do not change the opening opportunity of clamper (parallel walk beginning opportunity) and only to the locking of locking pin remove carry out correction opportunity, only the traverse speed of the parallel at wefting insertion initial stage changes as described above, and therefore the detected value on unwinding opportunity is less relative to the change of its correction amount.That is, opportunity is removed in the locking for locking pin, even if the degree in crank angle of correction 2 °, the change of the detected value on unwinding opportunity is also a lot of value less of 2 °.
Therefore, when producing deviation between the detected value and said reference value on unwinding opportunity, if opportunity is removed in the locking of correction locking pin, compared with the situation on the opportunity of opening of the correction clamper described in above-mentioned [background technology], excessive correction can not be carried out.Wherein, the correction on opportunity is removed in locking about locking pin, because the variable quantity on unwinding opportunity is less relative to its correction amount, therefore when above-mentioned deviation is large, need to take time and eliminate this deviation, the state cannot carrying out suitable wefting insertion therebetween continues, the possibility that the quality that therefore there is fabric reduces.
To this, according to the utility model, the correction on opportunity and the correction on the opportunity of opening of clamper is removed by the locking of the locking pin that hockets according to the correction model of the weave cycle unit preset, thus, repeatedly excessive correction need not be carried out as prior art, and promptly can carry out the elimination of deviation, therefore not use expensive encoder also can realize suitable wefting insertion and control.

Parallel storage facility 3 is configured in the upstream side of the Weft insertion nozzle 2 of the pull-out direction of parallel 9, and possesses the storage drum 34 of storage parallel 9 and be included in the parallel clamping device 31 storage drum 34 engaging the locking pin 32 of parallel 9.And, under parallel storage facility 3 utilizes locking pin 32 at parallel 9 and is locked on the state on storage drum 34, utilize rotation thread-carrier (omitting diagram) will be wound on storage drum 34 from the parallel 9 supplied for line body 39, thus, such as, the parallel 9 of the length of a wefting insertion institute wefting insertion is stored on storage drum 34.In addition, by removing the locking utilizing locking pin 32 pairs of parallels 9, thus it is unwinding to realize from the parallel 9 storage drum 34.
In addition, parallel clamping device 31 comprises above-mentioned locking pin 32, solenoid 33 for driver card shotpin 32.And, excitation, demagnetization is carried out by solenoid 33, carry out the locking releasing action that locking pin 32 leaves from storage drum 34 towards the locking action that storage drum 34 enters with locking pin 32, carry out above-mentioned locking action by locking pin 32 and become the state of parallel 9 locking on storage drum 34, in addition, by locking pin 32 carry out above-mentioned locking remove action and make parallel 9 can from storage drum 34 unwinding.It should be noted that, in the present embodiment, by making solenoid 33 excitation thus locking pin 32 carries out above-mentioned locking removes action, making locking pin 32 carry out above-mentioned locking action by solenoid 33 demagnetization.And the excitation of this solenoid 33 and demagnetization were carried out opportunity on the locking releasing opportunity preset and locking.Wherein, in the water jet loom as the utility model prerequisite, after the injection beginning opportunity be set in opportunity from aforesaid Weft insertion nozzle 2 expulsion pressure water is removed in above-mentioned locking.
Clamping device 4 between Weft insertion nozzle 2 and parallel storage facility 3, to be arranged by the mode supported relative to said frame.In addition, clamping device 4 comprises the movable holding sheet 41 holding parallel 9 and holds sheet 42 with fixing, and is arranged by movable holding sheet 41 and the fixing mode held sheet 42 with the parallel 9 from the storage drum 34 of parallel storage facility 3 to Weft insertion nozzle 2.And, in this clamping device 4, abut by making movably to hold sheet 41 with the fixing sheet 42 that holds and become and hold the state holding parallel 9 between sheet 42 movably holding sheet 41 and fix, in addition, leave from fixing holding sheet 42 by making movably to hold sheet 41, thus parallel 9 is opened, and become the state can carrying out wefting insertion.
It should be noted that, clamping device 4 drives the abutting action relative to fixing holding sheet 42 of movable holding sheet 41 and separating action to form by driving mechanisms such as such as solenoids, and this driving was carried out with the holding preset opportunity and the opportunity of opening.Wherein, in the water jet loom as prerequisite of the present utility model, be set in the above-mentioned opportunity of opening after above-mentioned locking removes opportunity and above-mentioned injection opportunity.Therefore, the beginning opportunity of walking becoming that parallel 9 starts to walk the opportunity of opening that parallel 9 opened by clamping device 4.
Unwinding sensor 5 is the sensor for detecting the parallel 9 unwinding from storage drum 34 when carrying out parallel 9 unwinding at every turn, makes unwinding sensor 5 arrange near storage drum 34 opposedly with storing drum 34.In addition, unwinding sensor 5 is generally the sensor of optical profile type, comprises light-projecting portion and light accepting part, such as, is carried out for making the light sent from light-projecting portion the sensor detected storing the side face reflection of drum 34 by light accepting part.And unwinding sensor 5 by blocking the mode of its light from unwinding parallel 9 storage drum 34, that is, detects parallel 9 by unwinding sensor 5 and the change of storing the light caused between drum 34 by light accepting part, detects that parallel 9 is unwinding thus.Like this, due to unwinding sensor 5 parallel 9 whenever from storage drum 34 unwinding with the amount of a volume time to parallel 9 by detecting, therefore, such as, if the length of the parallel 9 of a wefting insertion institute wefting insertion is equivalent to the length of the amount at storage drum 34 5 volume, then unwinding sensor 5 just carries out a wefting insertion and detects passing through of five parallels.It should be noted that, below, the situation length of the parallel 9 of a wefting insertion institute wefting insertion being equivalent to the length of the amount of five volume storage drums 34 is described.
As shown in Figure 2, the water jet loom in the present embodiment possesses: as the loom control device 6 of the main control unit of loom; To the Weft insertion controller 7 that the action of the component relevant to wefting insertion comprising aforesaid parallel clamping device 31 and clamping device 4 controls; For carrying out to the setting value, a reference value etc. of each device driven on water jet loom the loader 8 inputting setting.
Loom control device 6 is connected with above-mentioned unwinding sensor 5.And, loom control device 6 input have unwinding sensor 5 detect parallel 9 by time the unwinding signal of parallel that exports.In addition, loom control device 6 is connected with the encoder EN of the anglec of rotation (degree in crank angle) of the main shaft 11 for detecting water jet loom, and loom control device 6 is according to the signal detection degree in crank angle from this encoder EN.And above-mentioned encoder EN is the encoder generally used in water jet loom, as mentioned above, its resolution ratio is that 180 pulse/mono-enclose (0 ° ~ 360 °).Therefore, with 2 ° of units detect based on the pulse signal from encoder EN output, the degree in crank angle of main shaft 11, therefore, though unwinding sensor 5 detect the degree in crank angle on the opportunity of passing through of parallel 9 actual be 201 °, the detected value on unwinding opportunity is also 202 °.
And the degree in crank angle on this opportunity, when inputting the unwinding signal of parallel from unwinding sensor 5, detects as unwinding opportunity, and stores this unwinding opportunity detected by loom control device 6.It should be noted that, as mentioned above, during to carry out wefting insertion at every turn, with carry out a wefting insertion and from number of times corresponding to the volume number storing the unwinding parallel of drum 34 9, input loom control device 6 from the unwinding signal of parallel of unwinding sensor 5.Therefore, if as mentioned above the length of the parallel 9 of a hypothesis wefting insertion institute wefting insertion is the length of the amount being equivalent to five volumes storage drums 34, then loom control device 6 carries out the detection on five unwinding opportunitys at wefting insertion.
And, preset in loom control device 6 and store the unwinding opportunity which during the wefting insertion wefting insertion of the present utility model time to detect controls to use.And loom control device 6, when carrying out wefting insertion at every turn, reaches the opportunity of its set point number at the number of times of the detection on unwinding opportunity, Weft insertion controller 7 is exported to the detected value on the unwinding opportunity of this set point number.It should be noted that, with regard to the detected value on the unwinding opportunity of this Weft insertion controller 7 output, detected value closer to the amortization period (front end of parallel 9 arrives the opportunity of the position closer to the head end for line opposition side) of wefting insertion is considered more preferred from control angle, therefore in the present embodiment, a wefting insertion will be carried out as described above and in the detected value of repeated detection, the detected value (the 5th detected value) that finally detects controls for wefting insertion of the present utility model.And, also this set point number can be set to the set point number that can be undertaken by inputting setting from loader 8 changing.
