But, in the weaving of reality, the revolution of the main shaft that sets when weaving sometimes corresponding to as various types of service conditions of the situations such as the production schedule of the state of flight of the weft yarn that causes of environment when weaving or its fabric change.Particularly, when weaving identical weaving cotton cloth, on the standard revolution of main shaft is set at 400r/m and weaves, but according to as environment during above-mentioned weaving etc. also sometimes the revolution of main shaft is set at 420r/m, also be set at 380r/m sometimes.Thereby, imagine the multiple spindle revolutions that can set loom.
Like this, imagine under the situation of a plurality of kinds, if want to adopt above-mentioned conventional art to make wefting insertion condition corresponding to a plurality of kinds in advance to the Weft insertion controller storage, to keep 1 pair 1 relation, then this preparation setting work becomes very numerous and diverse a lot of times of needs and time.In addition, be meant and select the function of wefting insertion condition to be made as effective setting this said " preparing to set " being used to.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of weft inserting apparatus of fluid jet type weaving machine is provided.Its problem provides a kind of in the fluid jet type weaving machine based on the revolution of main shaft change wefting insertion condition, can simplify the weft inserting apparatus of the preparation setting work of relevant wefting insertion condition.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: the invention of the weft inserting apparatus of fluid jet type weaving machine with the wefting insertion controller that possesses the wefting insertion condition of selecting to be used to control the wefting insertion associated apparatus as prerequisite.
And the weft inserting apparatus of above-mentioned fluid jet type weaving machine is characterised in that to possess: memory, store in advance relevant main shaft revolution boundary value and with the wefting insertion condition corresponding to the magnitude relationship of boundary value; Comparator, relatively the revolution of boundary value and main shaft and will with the corresponding signal of the magnitude relationship of boundary value is outputed to the wefting insertion controller, the wefting insertion controller receives from the input of the signal corresponding with magnitude relationship of comparator and selects corresponding wefting insertion condition from memory.
No matter fluid jet type weaving machine comprises the number of the wefting insertion series of above-mentioned wefting insertion associated apparatus, can all use identical boundary value and/or identical wefting insertion condition to it.Yet, in the loom that possesses 2 above wefting insertion series, the weft yarn that makes the different yarn variety of state of flight mix and with and when weaving, also existing sometimes can't be with the situation of identical wefting insertion condition correspondence.For this situation of correspondence, for example preferably be made as follows.That is, fluid jet type weaving machine is the multicolor weft insertion loom that possesses according to 2 above wefting insertion series of yarn variety, and memory is for storing the memory according to a plurality of boundary values of yarn variety in advance.And fluid jet type weaving machine is the multicolor weft insertion loom that possesses according to 2 above wefting insertion series of yarn variety, and memory is for storing the memory according to the different wefting insertion condition of yarn variety in advance.In addition, above-mentioned said " wefting insertion series " is meant in common loom, realizes the affiliated group of a plurality of wefting insertion associated apparatus (length measuring weft storing device, main burner, auxiliary jet etc.) of 1 wefting insertion by the collaborative work running.
Compared with prior art, the invention has the beneficial effects as follows: according to the weft inserting apparatus of loom of the present invention, about the boundary value of the wefting insertion condition that is used for controlling the wefting insertion associated apparatus being input as of being stored in advance that the preparation of memory sets and the revolution of relevant main shaft and with the wefting insertion condition corresponding to the magnitude relationship of boundary value, compared with the pastly can finish with less condition.Its result is because the preparation setting work of relevant wefting insertion condition need not as all revolutions of imagining were stored corresponding wefting insertion condition in advance with 1 pair 1 relation in main shaft in the past, so can be time saving and energy saving.
More specifically, can only expect that in the past the revolution to the main shaft of each imagination sets the wefting insertion condition with 1 pair 1 relation.Yet, the application's inventor find if the revolution of main shaft be to a certain degree scope (for example, about the 200r/m of front and back), even under identical wefting insertion condition, also can carry out the wefting insertion of permissible level, based on its idea, can hold as scope with the revolution of the main shaft of identical wefting insertion condition correspondence, and the border of this scope will be set as boundary value, according to selecting the wefting insertion condition with the magnitude relationship of boundary value.Therefore, a plurality ofly weave contemplated spindle revolutions, also can significantly reduce and prepare the wefting insertion condition that the setting stage sets, thereby obtain above-mentioned effect in order to carry out this even exist.
Possess in the loom of 2 above wefting insertion series, the weft yarn of the different yarn variety of state of flight is mixed and with and when weaving, also having can't be with the situation of identical wefting insertion condition correspondence.Therefore, make according to a plurality of boundary values of yarn variety or be stored in the memory in advance according to different wefting insertion condition to the magnitude relationship of boundary value, thus also can be corresponding with the loom that uses diversified weft yarn, time that this preparation setting work is required and time to alleviate effect higher.

The specific embodiment
As using multicolor weft insertion loom of the present invention, the major part of fluid injection-type (air injection type) multicolor weft insertion loom is shown among Fig. 1.And, in the following description, narrate for following example, weave and comprise, in weaving, change the loom (for example terry cloth loom) of the revolution of main shaft 41 along with the change of this weft count according to the weaving cotton cloth 28 time of the different weft count of this multicolor weft insertion loom part.
In the weft inserting apparatus 11 that possesses 2 wefting insertion series 1,2 shown in Figure 1 and Weft insertion controller 46, weft yarn 14 with each wefting insertion series 1,2 wefting insertion is extracted out from the yarn body 13 that supplies that is supported by confession yarn body frame 12, for example import to the inside of the yarn winding arm 16 of drum length measuring weft storing device 15, when the outer peripheral face of the drum barrel 17 of inactive state ended by card shotpin 18 cards, the rotational motion of twining arm 16 by yarn was wrapped in the outer peripheral face of drum barrel 17.Thus, the weft yarn 14 of 1 wefting insertion Len req is wrapped in the outer peripheral face of drum barrel 17, the storage latitude during to the wefting insertion of weft yarn 14 till.
Length measuring weft storing device 15 (rotational motion of yarn winding arm 16 and the advance and retreat motion of card shotpin 18) or wefting insertion described later pass through selecting sequence (selecting sequence of the wefting insertion series) action of the wefting insertion controller 49 of the Weft insertion controller 46 in the loom control device 45 based on the weft yarn of stipulating at the wefting insertion pattern 14 with main burner 21.
Begin regularly at wefting insertion, if driven the card shotpins 18 corresponding with weft yarn 14 by 49 selections of wefting insertion controller and retreated from the outer peripheral face of drum barrel 17 by operator 19, the weft yarn 14 that then is wrapped in 1 wefting insertion Len req of drum barrel 17 peripheries becomes the state of can untiing on drum barrel 17.And, weft yarn 14 from drum barrel 17 connect to wefting insertion with main burner 21, and untie from drum barrel 17 by the injection of main burner 21 and to carry out wefting insertion.
The main burner 21 corresponding with selecteed weft yarn 14 begins regularly injection towards the opening 25 initiation pressure air of warp thread 24 at the wefting insertion that sets, sustained firing between the injection period that sets, thus with weft yarn 14 wefting insertion of predetermined length in opening 25.Weft yarn 14 flies along the weft yarn flight path in the opening 25 by this wefting insertion action.In addition, pressure air is supplied with from pressure air source 35, and is adjusted to after the air pressure that is fit to wefting insertion by pressure regulator 36, supplies to main burner 21 through electromagnetic switch valve 37.Electromagnetic switch valve 37 is by the control of wefting insertion controller 49, based on moving in the weft yarn selecting sequence of wefting insertion pattern regulation.
As above-mentioned, the weft inserting apparatus 11 of Fig. 1 is the device corresponding to 2 look wefting insertion, but when being the device corresponding to multicolor weft insertion more, be provided with according to polychrome number (radical of weft yarn 14) for yarn body 13, length measuring weft storing device 15 and main burner 21 etc., and based on carrying out the wefting insertion action in the weft yarn selecting sequence of wefting insertion pattern regulation.
By the weft yarn 14 of wefting insertion along in the process of the flight path in the opening 25 flight, organize auxiliary jet 22 more and pressure air sprayed simultaneously or relaying is ejected into the weft yarn flight path towards the heading of weft yarn 14, aloft weft yarn 14 is applied power to the wefting insertion direction.In addition, pressure air is supplied with from pressure air source 35, and is adjusted to after the suitable air pressure to supply to through the electromagnetic switch valve 39 corresponding to each group by pressure regulator 38 and respectively organizes auxiliary jet 22.The timing that each electromagnetic switch valve 39 sets by being controlled at of wefting insertion controller 49 applies power to aloft weft yarn 14 to the wefting insertion direction from auxiliary jet 22 expulsion pressure air to the auxiliary jet 22 supply pressure air of correspondence group.
Above-mentioned auxiliary jet can be a pressure-regulating valve with pressure regulator 38.Yet, because of in existing problems aspect the responsiveness, optionally switch passage according to a plurality of paths of the number of the force value of counting or being switched of the wefting insertion series 1,2 that has pressure-regulating valve separately etc. so preferably pressure regulator 38 is made as by transfer valve.
During the normal wefting insertion of weft yarn 14 injection action by main burner 21 and many group auxiliary jets 22, the beating motion of this weft yarn 14 by reed 27 beats up to weaving cotton cloth 28 fell 29, inweave and weave cotton cloth after 28, cut off by confession yarn scissors 30, from weft yarn 14 disconnections of main burner 21 inside in the wefting insertion side.
Whether normally having carried out wefting insertion detects by bobbin feeler 31.Bobbin feeler 31 the wefting insertion opposition side weave cotton cloth 28 knit end parts near the position and further to the wefting insertion direction away from 2 positions of position according to from judging whether normally to have carried out wefting insertion with the 1st sensor of weft yarn flight path arranged opposite and the detectable signal of the 2nd sensor.
Near the 1st sensor of 28 the position of knitting end parts of weaving cotton cloth is arranged on 14 positions that can arrive of weft yarn of normal wefting insertion, surveys the front end of the weft yarn 14 of normal wefting insertion at this.This detection is by relatively the level and the reference signal level of the detectable signal of inherent the 1st sensor generation in normal arrival period (during the detection of setting) of weft yarn 14 are carried out.Thereby, although can detect the front end wefting insertion of the position of no show the 1st sensor bad (short latitude, curved latitude etc.) still that has carried out wefting insertion weft yarn 14 according to the 1st sensor.In addition, on the angle of rotation of main shaft 41, set usually during the detection.
During above-mentioned detection, the 1st sensor produces the output signal according to this when detecting the arrival of weft yarn 14.At this moment, bobbin feeler 31 is based on the yarn signal S1 that produces from the 1st signal of sensor corresponding to normal wefting insertion, and this yarn signal S1 is delivered to master controller 47 in the loom control device 45.Master controller 47 continues the operation (weaving) of loom with the condition that exists for corresponding to the yarn signal S1 of normal wefting insertion.
During above-mentioned detection, when not producing yarn signal S1, when bad and the 1st sensor of wefting insertion promptly having taken place failing to detect the arrival of weft yarn 14, bobbin feeler 31 is judged as the unusual of wefting insertion and output stops the latitude signal and (also claims " the 1st stops the latitude signal ".) S2, and this is stopped latitude signal S2 deliver to master controller 47.And master controller 47 is if reception stops latitude signal S2, and then execution stops control immediately, and loom is stopped with the predetermined angular of main shaft 41.
Than the 1st sensor more to the wefting insertion direction away from the 2nd sensor of position opposed at position and the weft yarn flight path of weft yarn 14 no shows of wefting insertion normally, for survey as blowing of weft yarn 14 break or the wefting insertion of long latitude bad and be provided with.Carry out this detection in the level of the detectable signal of the 2nd sensor generation and the level of reference signal the unusual arrival period (arrival angle) by inherent weft yarn 14 during the comparison detection.
In addition, on the rotational angle of main shaft 41, set usually during the detection.During this was surveyed, bobbin feeler 31 was judged as the unusual of wefting insertion when importing from the 2nd signal of sensor, and generation stops the latitude signal and (is also referred to as " the 2nd stops the latitude signal ".) S3, and this is stopped latitude signal S3 deliver to master controller 47.Master controller 47 stops latitude signal S3 if receive the 2nd, and is identical when then stopping latitude signal S2 with reception the 1st, and loom is stopped with the predetermined angular of main shaft 41 immediately.
In order to detect the rotational angle θ of main shaft 41, angle detector (encoder) 43 is arranged in main shaft 41 bindings.Encoder 43 produces the signal of the rotational angle θ of main shaft 41 in weaving, and this is sent into the master controller 47 of loom control device 45 and the comparator 48 and the opening control device 44 of Weft insertion controller 46.
Loom control device 45 is made of master controller 47 and Weft insertion controller 46 for the state control loom of the rotation of the main shaft 41 that is synchronized with loom or carry out other required control.
In memory 51, set by setting apparatus 52 by the staff in the stage that preparation is set, store respectively relevant main shaft 41 revolution boundary value and with the 2 kind wefting insertion conditions corresponding to the magnitude relationship of boundary value.In the present embodiment, each wefting insertion series is made as with identical wefting insertion condition and carries out wefting insertion action.Thereby boundary value and wefting insertion condition are used something in common in each wefting insertion series 1,2.
The wefting insertion condition corresponding to switching signal S7 is selected in the input that wefting insertion controller 49 receives from the switching signal S7 of comparator 48 from 2 kinds of wefting insertion conditions that are stored in memory 51 in advance.And wefting insertion controller 49 is selected the corresponding wefting insertion series of signal S5 according to selected wefting insertion condition control with the yarn variety from opening control device 44.Particularly, for example the wefting insertion condition is made as wefting insertion and begins regularly (making the injection beginning timing etc. of fluid of driving timing (weft yarn is untied regularly), the main burner 21 of the operator 19 that card shotpin 18 retreats).And, according to this wefting insertion condition, serving as basis control with the suitable rotational angle θ of main shaft 41 selects the action of the length measuring weft storing device 15, main burner 21, auxiliary jet 22 etc. of the wefting insertion series of signal S5 corresponding to yarn variety, and the wefting insertion action of the weft yarn of selecting according to the wefting insertion series of correspondence 14 is carried out.
As mentioned above, " wefting insertion series " is meant the group under a plurality of wefting insertion associated apparatus that turn round for collaborative work realizes 1 wefting insertion.And " wefting insertion associated apparatus " is the device that participates in from the wefting insertion of the weft yarn 14 extracted out for yarn body 13, be meant be present in than for yarn body 13 more by the device in downstream.This weft yarn associated apparatus comprises length measuring weft storing device 15, main burner 21, auxiliary jet 22.But among these, auxiliary jet 22 is used in each wefting insertion series 1,2 jointly.
Above-mentioned loom control device 45 conducts constitute by the combination of the piece of difference in functionality.This loom control device 45 can make up the device that is made of each piece and realize, also can predetermined software be installed and this software is carried out at computer, constitute each piece of output input mechanism, storing mechanism, s operation control mechanism and the software collaboration work of computer thus, and realize by these pieces.
And,, but for example be provided with to communication setting apparatus 52 such as touch panel formula or keyboard for the data of opening control device 44, master controller 47 and memory 51 being set the weaving condition that comprises the wefting insertion condition etc.
In the stage of preparing to set, above-mentioned Weft insertion controller 46 is set the wefting insertion condition of boundary value and switching.This preparation is set and consider the weaving of imagining in the factory of weaving of using this loom in this loom, can be undertaken by this staff who weaves factory, perhaps also can be set storage in advance and provide as the system of Weft insertion controller 46 in loom manufacturer side.
Preparing the boundary value that the setting stage sets and the wefting insertion condition is following obtains.For example, will in this loom, imagine weave in realistic scale under the maximum number of revolutions of main shaft 41 be made as about 800r/m.In the case, obtain the wefting insertion condition that to carry out the wefting insertion of permissible level with maximum number of revolutions 800r/m by test weaving.Particularly, if test is suitable for the wefting insertion condition to the revolution of the more approaching main shaft 41 of maximum number of revolutions 800r/m, then also can carry out the wefting insertion of permissible level fully with maximum number of revolutions 800r/m, but this moment since can't be fully the lower revolution of correspondence, so test is suitable for the wefting insertion condition of further slow speed successively, in the wefting insertion condition of the wefting insertion that also can carry out permissible level with maximum number of revolutions 800r/m, obtain the wefting insertion condition that is suitable for minimum revolution.In addition, the wefting insertion of permissible level comprises certainly and is suitable for most woven wefting insertion, is meant the wefting insertion that can assure as the desired minimum quality of weaving cotton cloth.
Then,, test the wefting insertion that just can carry out permissible level with the low revolution of which kind of degree, obtain the lower limit (minimum revolution) of the revolution of main shaft 41 the wefting insertion condition of obtaining like this.And, because this minimum revolution of obtaining becomes the lower limit based on the revolution of the main shaft 41 of the wefting insertion that can carry out permissible level of this wefting insertion condition, so when will this minimum revolution being defined as boundary value, this wefting insertion condition is defined as and the corresponding wefting insertion condition of higher revolution (revolution 〉=boundary value) more than the boundary value.
Then, regulation with revolution (revolution＜boundary value) the corresponding wefting insertion condition lower than this boundary value.For example, if the boundary value of obtaining during hypothesis is above-mentioned is revolution 500r/m, and the minimum revolution of imagination is 300r/m in the weaving of this loom, and then can obtain in the wefting insertion condition that the scope of the revolution of this 500～300r/m is carried out the wefting insertion of permissible level same as described abovely.
And, to arrive setting apparatus 52 as above boundary value of obtaining and wefting insertion condition entry, when thus boundary value being set in the predetermined field storage of memory 51, make each wefting insertion condition corresponding to being set in other presumptive areas of memory 51 with the magnitude relationship of boundary value (〉=,＜) and storing.
As above according to the present invention, in the stage of preparing to set, can stipulate as 1 group with the scope of revolution of main shaft 41 that identical wefting insertion condition is carried out the wefting insertion of permissible level, and set 1 wefting insertion condition at per 1 group, so the number of the wefting insertion condition that should set significantly reduces, simplify preparation setting work.That is, need not to set as in the past to the multiple revolution of the main shaft 41 of imagination in the weaving of this loom separately with 1 pair 1 the wefting insertion condition that concerns correspondence.
The invention is not restricted to the foregoing description.For example, in the above-described embodiments, only regard the group of the revolution of main shaft 41 as to 1 boundary value 2 up and down, but when the scope of the revolution of the main shaft 41 of imagination is wide in the weaving of this loom (in other words, when the maximum number of revolutions of main shaft 41 is higher), also sometimes can't be with 1 boundary value correspondence.Promptly, when the revolution of main shaft 41 was wide scope, if revolution that will this wide scope is divided into 2 groups, then the scope owing to 1 group also became wide, so, the scope of the wefting insertion of permissible range then in gamut, also might occur to carry out if be somebody's turn to do the gamut of organizing with identical wefting insertion condition wefting insertion.In this case, a plurality of boundary values can be set, the scope of the revolution of contemplated main shaft 41 is divided into group more than 3.In addition, in the case the selection of wefting insertion condition also according to carrying out with the magnitude relationship of each boundary value.
And in the foregoing description, the revolution of the main shaft 41 that will compare with comparator 48 and boundary value is made as sets revolution (the revolution signal S6 that master controller 47 is selected based on density signal S4), but replaces this, also can be made as the revolution of detected reality.
In addition, in the above-described embodiments, comparator 48 receives the input of revolution signal S6 and the revolution and the boundary value of comparison main shaft 41, but is not limited thereto.Promptly, as above-mentioned embodiment, make under the situation that the revolution of density signal S4 and main shaft 41 sets accordingly, also can followingly carry out: comparator 48 receives the input of density signal S4 and when distinguishing the revolution of memory 51 pairing main shafts 41, the revolution of boundary value and the above-mentioned main shaft of distinguishing 41 relatively, will with the corresponding signal of the magnitude relationship of boundary value is outputed to wefting insertion controller 49.
And, in the above-described embodiments, irrelevant with the yarn variety that carries out wefting insertion, when the revolution of main shaft 41 is identical, be made as according to identical wefting insertion condition and control each wefting insertion series 1,2 and carry out wefting insertion, but, under the situation that the state of flight of weft yarn 14 differs widely when for example comprising the multiple weft yarn 14 that uses in the weaving of can imagining carrying out wefting insertion with identical wefting insertion condition in this loom, preferably press yarn variety setting wefting insertion condition and/or boundary value.Yet, may not be defined in by yarn variety and carry out different settings, also a plurality of weft yarns 14 with identical wefting insertion condition wefting insertion can be made as 1 group, and all weft yarns 14 are divided into a plurality of groups, set wefting insertion condition etc. by group.And, in weaving, and when being used in the weft yarn 14 of other kinds that state of flight is different under this identical wefting insertion condition, be made as that selection signal (yarn variety signal S5) from the wefting insertion series of opening control device 44 is input to comparator 48 and wefting insertion controller 49 gets final product.And, be made as following getting final product: comparator 48 is selected boundary value according to pairing yarn variety based on the selection signal of wefting insertion series, compare action by this boundary value, wefting insertion controller 49 is selected corresponding wefting insertion condition based on the result of determination of the magnitude relationship by comparator 48 and the selection signal of yarn variety.
In addition, for in the above-described embodiments as the loom of the revolution of change main shaft 41 in the weaving of prerequisite, for example, as terry cloth loom, when there is the revolution of standard in 2 kinds of revolutions of height of main shaft 41, can be that benchmark comes the regulation boundary value with the revolution of this standard.Particularly, when 2 kinds of revolutions of the height of above-mentioned main shaft 41 are 600r/m and 400r/m, can from can with the wefting insertion condition that is suitable for 600r/m carry out permissible level wefting insertion main shaft 41 revolution scope and can carry out the scope dictates boundary value of revolution of main shaft 41 of the wefting insertion of permissible level with the wefting insertion condition that is suitable for 400r/m.
And, in the foregoing description, what be made as the revolution that carries out boundary value and main shaft 41 in weaving relatively reaches selection based on the wefting insertion condition of the result of determination of the magnitude relationship by this comparison, but the invention is not restricted to this, also can weave advance row bound value and main shaft 41 respectively set revolution relatively reach based on this comparison set the setting of the corresponding wefting insertion condition of revolution with each, and according to the setting revolution selection wefting insertion condition of change during weaving.In addition, in the above-described embodiments, the loom of revolution with change main shaft 41 in weaving is a prerequisite, but does not change the revolution of main shaft 41 in also can applying the present invention to weave and carry out the setting of weaving the wefting insertion condition before the beginning in the woven loom with the setting revolution of main shaft 41.
And the wefting insertion that the wefting insertion condition of selecting according to the revolution of main shaft 41 is not limited to the foregoing description begins regularly, can be made as the wefting insertion stop timing or spray the pressure of fluid, also can be made as wefting insertion and begin regularly and the combination of wefting insertion stop timing and pressure.
