According to another embodiment of the present invention, for each valve of the air-jet loom shown in arbitrary embodiment among each group structure embodiment, the control signal of confirming each valve is to provide air-flow to the corresponding relay jet head sets.This control signal make its each valve of control control first, second with the 3rd functional area in the air rate of each relaying shower nozzle; Thereby the auxiliary parallel of carrying; Thereby the parallel to first functional area that passes shed open quickens; Thereby carry parallel to pass second functional area of shed open with the speed of substantial constant alternatively, thereby and when parallel is carried the 3rd functional area that passes shed open, parallel is slowed down and make its stretching, extension.Can assist the conveying of parallel through the air rate that the relaying shower nozzle relevant with each functional area passed in control.
Can be provided for the control signal of each valve through suitable interface (for example keyboard or touch-screen) by the operator, valve and relaying jet head sets are as many in certain embodiments.Perhaps, can take control signal from memory read as the part of the controller of air-jet loom in each valve.
Confirm that the control signal that is used for each valve can comprise the one group of predetermined control signal that is used for valve of predetermined control signals selection that is used for valve from many groups.The many groups predetermined control signal that is used for valve can be stored in the question blank, and question blank is stored in the memory cell of processing unit.Can based on for example with above-mentioned selection suitably the similar information of air rate of group select automatically, or select through the interface by the operator.
The control signal of valve is relevant with the known air flow rate value of the relaying jet head sets that is connected to valve.Therefore, through each valve is selected control signal, the predetermined value of air rate can be provided to the relaying jet head sets that is connected to valve.
In case the control signal to valve is confirmed, calculated alternatively to the processing unit through controller 20, then just control signal is offered each valve with through each relaying jet head sets being provided compressed air control the air rate from the relaying jet head sets.
Should be appreciated that through each valve is confirmed appropriate control signals, can provide air rate to distribute Fig. 2,4,6,8,10, its some instance shown in 12 and 13 the relaying jet head sets to realize desired air rate.
For example return not the parallel insertion system of loom shown in the structure embodiment on the same group, also can comprise step each valve calculation control signal according to the method for various embodiments of the present invention.Controller 20 can be confirmed this control signal.For example, controller 20 can use air rate value to be supplied, is used for this value is compared with the air rate value that air rate value and valve are set in the tracing table that links.From tracing table, controller 20 can obtain producing by the needed valve of analog value and set to realize the control signal of respective air flow rate value.Tracing table can be set the air rate value respectively and link with the valve that is used for each valve.Certainly, also can use other appropriate algorithm well known by persons skilled in the art.
In addition; Controller 20 can be according to the weaving end-around carry; For example in choke valve 13 [i] and the shutoff valve 12 [i] each confirmed to launch constantly and the optional interruption moment according to the value of the position, angle of the main shaft of loom, with will switch to respectively the control signal of valve corresponding to launch, the value of for use or intermediateness.
During the method for using according to the embodiment of the invention; Controller 20 can will be used for the corresponding choke valve 13 [i] related with this group in the moment that the given trunk jet head sets starts and switch to the value corresponding to the initiate mode of respective valve with the control signal of the related shutoff valve 12 [i] of this group; Causing provides definite air rate value to respective valve; And interrupting constantly after a while; The control signal that will be used for respective valve 13 [i], 12 [i] switches to the value corresponding to the dormant state of respective valve, therefore interrupts to the corresponding relay jet head sets definite air rate value being provided.
Controller 20 can be suitable for each shutoff valve 12 [i] is confirmed, for example calculated and launch constantly and the interruption moment, the setting that can be suitable for calculating choke valve 13 [i], and can be suitable for based on each the desired air rate value calculation control signal that is used for the relaying shower nozzle.Sort controller 20 also can be suitable for confirming the position, angle of main shaft, for example is used for confirming the process of weaving circulation.
The information that controller 20 can be suitable for obtaining about air rate value to be used perhaps obtains treating the information about yarn types and yarn property as the weft thread insertion.This information can obtain through one or more parallel preparation machine 7A, 7B, 7C alternatively.
The parallel preparation machine is not limited to parallel preparation machine 7A, 7B, the 7C shown in the figure, and other parallel preparation machine also can be used on according to parallel of the present invention and inserts in the apparatus.For example, can use from EP268313A1, parallel preparation machine or similar devices that EP315235A1 is known for this reason.
Controller 20 can comprise such as keyboard or such as the interface of the pointing device of mouse or tracking ball, be used to make the operator to indicate and use which air rate.
Perhaps, controller 20 can comprise such as keyboard or such as the interface of the pointing device of mouse or tracking ball, be used to make the operator can indicate the yarn that uses which kind of type as weft thread.Controller 20 can be suitable for based on the yarn information definition air rate for use that provides like this.
Controller 20 can comprise keyboard or screen or touch-screen with operator's interchange information.
Controller 20 can be suitable for according to the adjusted data of flight situation that are inserted into the yarn in the shed open; For example specifically be to be used to regulate the air rate value and to be used for, but be not limited thereto the launching and interrupt the moment of choke valve 13 [i] and shutoff valve 12 [i] switch-over control signal.
For example, controller 20 can be suitable for confirming, for example calculate the position, angle of the main shaft of loom, therefore calculates the moment that weft thread passes yarn detector 6, and indication is inserted accomplishing parallel constantly with respect to this of weaving circulation.Arrival through recording is compared with the arrival of its expectation, and controller 20 can notice that this arrival is early than expection or is later than expection.It is poor that controller 20 can be suitable for calculating the arrival and the average time between the expection arrival that record.If average arrival is later than expection arrival, then yarn tends to postpone to arrive in the cycle period of weaving.If average arrival early than expection arrives, then yarn tends to arrive in advance with respect to the weaving circulation.
Under the situation that yarn tends to arrive in advance, the controller 20 that is suitable for changing loom speed can increase the speed of loom, promptly shortens the time that loom is made a weft yarn.Alternatively or additionally, the controller 20 that is suitable for changing air rate can reduce to offer the air rate value of main jet gas blowout head, and also reduces to offer the air rate value of some or all relaying jet head sets alternatively.
Similarly, under the situation that yarn tends to postpone to arrive, controller 20 can reduce the speed of loom, promptly increases the time that loom is made a weft yarn.Alternatively or additionally, controller can increase the air rate value that offers main jet gas blowout head, and alternatively also increase the air rate value that offers some or all relaying jet head sets.
Yarn inserted characteristic, for example instantaneous filament speed during controller 20 can be suitable for measuring and insert.This controller can obtain signal from filament preparation machine 7A as shown in Figure 1,7B, the spiral sensor 70A of 7C, 70B, 70C respectively.Controller can be suitable for from the calculated signals of spiral sensor 70A, 70B, 70C or the speed that spins of definite weft thread.
Except the spiral sensor, alternatively can use the linear speed sensor or along the sensor that the weaving shed open is arranged calculate or definite parallel yarn insert during the insertion characteristic of parallel yarn.
Tend at filament under the situation of too fast flight, controller 20 can shift to an earlier date the interruption moment of relaying jet head sets and launch in advance alternatively constantly, even these early constantly, this weft thread to the guiding insertion remains very important.Alternatively or additionally, controller can reduce to offer the air rate value of main jet gas blowout head, and also reduce to offer the air rate value of some or all relaying jet head sets alternatively.
Similarly, under the situation that filament tends to fly too slowly, controller 20 can be postponed the interruption moment of relaying jet head sets and postponed alternatively and launching constantly, and this weft thread that guiding is inserted remains very important.Alternatively or additionally, controller can increase the air rate value that offers main jet gas blowout head, and alternatively also increase the air rate value that offers some or all relaying jet head sets.
Shown in Figure 14 to 17 (illustrated right hand bar shaped), this adjusting can be adjusted to the value that reduces with at least a portion of the predetermined air rate of relaying shower nozzle, and wherein this reduces to be less than or equal in each relaying jet head sets at least one group predetermined air rate value.In other words, can some or all the air rate value in each relaying jet head sets be reduced predetermined value.Typically reduce the factor between 15% to 30%.
In the embodiment of Figure 14, the value that the left side is represented is the value before regulating, and the value that the right is represented is the value after regulating.When continuous weft thread tends to insert at a relatively high speed, can carry out this adjusting.In this example, the air rate that is provided at relaying shower nozzle in the functional area 1 reduces by 10%, and the air rate of relaying shower nozzle reduces by 20% in functional area 2, and in functional area 3, does not provide the air rate of relaying shower nozzle to reduce.Preferably, the reduction of the air rate of relaying shower nozzle is chosen to 2 ratios height in zone 1 in the zone, because in regional 2, parallel only needs further the conveying, and parallel still must be accelerated in regional 1.In this example, in zone 3, do not regulate the air rate of relaying shower nozzle, thereby weft thread can be stretched.
In the embodiment of Figure 15, the air rate that flows out the relaying shower nozzle in the functional area 2 reduces, and flows out the air rate increase of relaying shower nozzle in the functional area 3.The weft thread that during initial part inserts, inserts in reality can carry out this adjusting when having reached relative high speed, for example has the speed that is higher than when extract the first or second average weft thread when twining out from preparatory bobbin winoler.This means that the winding time of for example leaving first or second winding is relatively low.Owing to this high speed that has reached, can reduce the air rate of relaying shower nozzles in the functional area 2.When the high speed of this parallel tool, increasing in the functional area 3 air rate of relaying shower nozzles, to keep this quick weft thread stretching, extension can be favourable.In other words; If the weft thread that inserts in this weft thread accelerating period has reached enough speed; Then the value represented of the right of Figure 15 is used for further inserting this weft thread; And if the weft thread that inserts in this weft thread accelerating period does not reach enough speed, then the value of the left side of Figure 15 indication is used for further inserting this weft thread.
According to unshowned alternative form, if record the weft thread rapid speed, for example only relaying shower nozzle 9,10 and 11 air rate can be reduced to the value of the right indication of Figure 15, and the air rate of other relaying shower nozzle is constant.According to unshowned another alternative form that is similar to the embodiment of Figure 15, can change the air rate of relaying shower nozzle 4 to 11 faster under the situation at weft thread, and the air rate of relaying shower nozzle 12 to 14 is constant fully.
In the embodiment of Figure 16, reduce the air rate that flows out the relaying shower nozzle in the functional area 3.The parallel yarn that during initial part inserts, inserts in reality can carry out this adjusting when only reaching relative low speed, for example has the speed that is lower than when extract the first or second average weft thread when twining out from preparatory bobbin winoler.This means that the winding time of for example leaving first or second winding is higher relatively.Owing to this low speed, can reduce the air rate of relaying shower nozzles in the functional area 3, can still keep this slow weft thread stretching, extension simultaneously.
In the embodiment of Figure 17, reduce the air rate of all relaying shower nozzles, the reduction amount of air rate depends on functional area thus.As long as weft thread enough arrives the opposite side of shed open and/or only otherwise the air rate that the weaving fault just can reduce the relaying shower nozzle takes place soon.For coarse staple fibre yarn, it seems optimal is the air rate that reduces in all functions zone, and for smooth filament yarn, maybe be more suitable be the air rate that only reduces functional area 2 interior relaying shower nozzles.In air-jet loom, knownly provide the quite coarse staple fibre yarn of comparison high air rate to smooth filament yarn.
Alternatively, this adjusting can make at least a portion of predetermined air rate value be adjusted to the predetermined value that multiply by a scale factor, and this scale factor is preferably less than 1.Should be appreciated that can carry out various programs makes controller itself change the air rate value according to the adjusting data that record He obtain.For example, when the bobbin variation detector detects when using new bobbin (bobbin), can carry out stepping and regulate.
For example, controller 20 can be suitable for to the relaying shower nozzle the air rate value, launch and interrupt constantly and the given setting of yarn property comes counting process to interrupt.Controller (number of times that interrupts of attention process be higher than predetermined can accept number of times) can reduce automatically or increase the air rate value can be gradually or the conversion of stepping ground launch and/or interrupt the moment.The process interruption times can change owing to this adjusting.
For the air rate value, launch and interrupt constantly and the given adjusting of yarn property is set, controller 20 can find further to regulate that to cause that the process interruption times increases too many.Like this, but the number of times accepted that controller 20 just self interrupts according to process defines the air rate value automatically, launches and interrupts constantly and the optimal given of yarn property is set.
Should be appreciated that these data also can be used by the operator, the operator possibly interrupt providing and begins the air rate value, launches and interrupt constantly and the adjusting of the setting of yarn property according to the process that the operator notices.
Controller 20 can be suitable for carrying out a plurality of instructions and routine, and when on the calculation element related with air-jet loom, carrying out, these instructions and routine can be made into the available computers program product that is used to carry out above-mentioned any method.This computer program can transmit on local or wide regional telecommunication network network.
Alternatively, these instruction and routines can be provided with the form of hardware.
