(by machinery or the decision of yarn kind, setting in advance is also passable so need not comprise cuit for the opening amount.)
(by machinery or fabric decision, setting in advance is also passable so need not comprise cuit for fabric width.)
2) harness motion condition
Retention period (in the following retention period of last retention period of Fig. 5) ... in last other retention period of branch that stops and stop down.Even,, also can before and after it, set different angles respectively about top dead-centre θ u in the last retention period and the bottom dead centre θ d in the following retention period.For example be expressed as 30 ° 30 °/90 ° 90 ° (stopping after going forward to stop back stop/preceding down stop down).The retention period of Fig. 2 is for during latter incorporated before dividing other stop to represent.
Stop phase place (stopping phase place under the stop phase place on Fig. 5) ... the position that will go up the anglec of rotation that stops the main shaft 10 that reaches other loom of branch that stops is down represented by the anglec of rotation of main shaft 10.For example, the beginning angle of other stop of branch that also can stop going up and stop down is as stopping phase place.And, at present embodiment, used the main axis rotation angle θ c in crosspoint (opening is regularly) as stopping phase place.And when using crosspoint θ c, 180 ° of the place aheads of crosspoint θ c (θ c-180 °) is defined as top dead-centre θ u, and 180 ° of rears of crosspoint θ c (θ c+180 °) is defined as bottom dead centre θ d.Even,, also can define the retention period simultaneously and stop phase place by using the beginning angle and the angle at the end of other stop of branch that stops and stop down.
At Fig. 2, when opening amount, fabric width, weave patterns, weft yarn kind are different from the content of frame of epimere,, can obtain the retention period and the crosspoint of all weaving conditions from this database by interpolation coefficient being taken advantage of the value with retention period, crosspoint.Even the retention period of the database of Fig. 2, crosspoint are to set during the wefting insertion of considering to determine by the input weaving condition.
As the formation of the harness motion condition database beyond Fig. 2, also can be according to Fig. 3, following carrying out.(a) of Fig. 3 makes in each value of each opening amount, fabric width, weave patterns, weft yarn kind and stores the retention period of a plurality of correspondences, the database in crosspoint respectively.By using augmenting factor, preferably prepare a plurality of databases and just can improve the calculation precision.And Fig. 3 (b) is, each value of corresponding opening amount, fabric width, weave patterns, weft yarn kind, weft count, loom rotation number is stored a plurality of paired retention periods, the example in crosspoint as far as possible.
Then, the harness motion condition is set to as follows.At first, from then on operating personnel's operating and setting device 5 is carrying out the weaving condition of woven fabric, in the time of specific heald frame 2, for example about frame number 1 following the input.
Weave patterns ... the limit sees that the weave patterns of Fig. 4 sets picture and set.At Fig. 4, the longitudinal axis refers to number of pick, and transverse axis refers to the number (sheet number) of heald frame 2.Represent that at weave patterns ■ heald frame 2 is positioned at top dead-centre, represents that heald frame 2 is positioned at bottom dead centre.C refers to yarn number (yarn kind).Setting weave patterns at Fig. 4 is that the sheet number of heald frame 2 is 16, and 15 throw a spear as 1 repetition.

Yarn kind ... weft yarn: cotton yarn, 30S
Weft count ... 20 throw a spear/inch
Opening amount ... 100mm is not (the opening amount of each frame number not simultaneously, in each frame feed opening amount.Or designating frame number also can.)
Fabric width ... 190mm
If operating personnel are by these parameters of setting apparatus 5 input, exerciser 8 then extracts value corresponding to the harness motion condition of the weaving condition of input from the harness motion condition database of Fig. 2 of being stored in memory 7.If inconsistent, then carry out the interpolation calculation, and obtain the value of harness motion condition from approximate mutually weaving condition with the weaving condition that is stored in the harness motion condition database.
Promptly, be stored in advance under at least one key element of weaving condition of harness motion condition database of memory 7, calculate interpolation coefficient corresponding to the key element of the weaving condition of setting, harness motion condition and interpolation coefficient according to the harness motion condition database, for example by harness motion condition and the interpolation coefficient of multiplying each other, interpolation is calculated out the harness motion condition corresponding to the weaving condition of setting.
Specifically, for example at the harness motion condition database of Fig. 2, the weaving condition of the frame of epimere and the term harmonization of input, when the loom rotation number is a value between 800～900, the retention period of the A of Fig. 2 and the value in crosspoint and, between 2 data of the value adjacency in retention period of the B of Fig. 2 and crosspoint, by by the additional calculation of ratio, calculate retention period and crosspoint for the loom rotation number of each value of A, B and input.And, to weft count, be that (between B, the C) too between 15～20 for example at weft count.
And according to the interpolation calculation for the weaving condition of the frame of Fig. 2 epimere, for example the retention period is used augmenting factor a, augmenting factor b, augmenting factor c, augmenting factor d, is obtained by the formula value * a * b * c * d that is similar to of table [retention period=].At this, each augmenting factor is rule of thumb and the value of setting.Augmenting factor a is relevant with opening amount L, obtain by a=L/100, augmenting factor b is relevant with fabric width S, obtain by b=S/190, augmenting factor c is relevant with weave patterns C, and by the number of starts of heald frame 2 with stop the value that the total of number of times decides, and augmenting factor d is the value by the kind of weft yarn and thickness decision.So, by the importing of interpolation calculation, in table even without suitable data, also can be by 1 table (database) correspondence.
When the harness motion condition was obtained according to the extraction of harness motion condition database or by the interpolation calculation, exerciser 8 was sent to controller 6 with its harness motion condition, and at its automatic setting.Behind automatic setting, if weave beginning, 6 bases of controller are controlled the rotation of a plurality of motors 3 corresponding to the harness motion condition of the weaving condition of input, and harness motion is supplied in each heald frame 2.
Even the harness motion condition database of Fig. 2 is combined into a database with retention period and crosspoint (stop phase place), but also retention period and crosspoint can be constituted as each other database respectively.
And exerciser 8 is calculated after the harness motion condition, and before weaving beginning, display 9 shows the harness motion condition of obtaining as required.Fig. 6 is that at each heald frame 2, corresponding opening curve is represented the example in retention period (going forward to stop the back stop, stop after the preceding stop down down), crosspoint.In this example, the harness motion condition that operating personnel obtain from the displaying contents affirmation of display 9 according to the harness motion condition of displaying contents, or is revised after the harness motion condition as required, begins to weave.And, as shown in Figure 2, with the retention period preceding when using during latter incorporated, with the expression of Fig. 6, before and after identical value is distributed in.And, become at Fig. 6, as stop phase settings crosspoint, but not that setting each beginning angle that stops in crosspoint is also passable.
[embodiment 2]
At memory 7, remove the harness motion condition database of embodiment 1, also preserve load database in addition, this load database is by actual the knitting of a plurality of harness motion conditions, to put aside each load that motor 3 reality when driving each heald frame 2 are born.
Fig. 7 is represented load database by the chart form.The figure of a plurality of other key elements of storage is also passable in load database.And, not actual load, use also passable as load the theoretical value on calculating.
And,, except that the parameter of embodiment 1, also append the following parameter of the key element of relevant load in the harness motion condition of load database.These parameters are imported as weaving condition.
1) weaving condition appends parameter
Warp thread kind ... the thickness of warp thread (yarn), for example 20S
Warp thread radical ... the warp thread radical is many more is just big more to the load of motor 3.
Target warp tension value during running ... warp tension is big more is just big more to the load of motor 3.
Heald frame frame weight ... weight is heavy more is just big more to the load of motor 3.
At first, operating personnel's operating and setting device 5, the feasible value (in other words, to the actual effect torque, be the ratio of nominal torque) of the load of input motor 3.Usually the feasible value of setting is about 80%～90%, and these feasible values can change when loom stops.And the feasible value as the prior assumed load of fixed number when loom goes on the market is also passable.
Utilize setting apparatus 5 that the feasible value of the load of motor 3 for example is input as [80%], by import content similarly to Example 1 as weaving condition, exerciser 8 extracts or interpolation is calculated out value corresponding to the harness motion condition of the weaving condition of input from the harness motion condition database.The interpolation calculation is carried out similarly to Example 1.
And then exerciser 8 extracts or replenishes the value of interpolation calculation and the load of the harness motion term harmonization of obtaining from load database.If the feasible value that the load of obtaining overloads, exerciser 8 impels the correction of carrying out weaving condition in display 9 demonstration rub-out signals.At this moment, show that simultaneously the feasible value of the load obtain and load is also passable.
Fig. 8 is an example that is shown by display 9.Among Fig. 8, infer load in each frame number demonstration of heald frame 2.In the example of this Fig. 8, the load of the 8th frame is 90%, has surpassed the feasible value [80%] of load, and has shown that in the load left side of inferring of the feasible value that overloads [*] impels operating personnel to revise weaving condition or harness motion condition.Do not show *, the feasible value that overloads to infer load also passable with color differentiatings such as redness.The operating personnel that discovery * mistake shows then revise weaving condition or the harness motion condition makes the feasible value that is contained in load.
During feasible value that the load of obtaining overloads, the error light of loom is lighted, or given the alarm.At this moment, can not use display 9.
[embodiment 3]
And according to the feasible value of harness motion condition database and load database and load, also can automatically obtain load becomes the following recommendation harness motion condition of feasible value.At this moment, if utilize setting apparatus 5 input weaving conditions, 8 of exercisers are from being stored in the load database of memory 7, extract or interpolation is calculated out with the feasible value of the load of input with from harness motion term harmonization, connection to load that the harness motion condition database is obtained and become recommendation harness motion condition below the feasible value.Particularly, load database at Fig. 7, priority with loom rotation number, stop, compare to the loom rotation number of next grade of setting or for the value of the load that stops and the feasible value of load, press the order of loom rotation number, stop, grade of a grade reduce gradually and proceed to load become the feasible value of load following till.Perhaps also can use interpolation coefficient as embodiment 1.
Even, by obtaining the harness motion condition of recommending, for example only revise when stopping, its result, weaving condition can not change.And same, for example revise the loom rotation number, the change weaving condition also can.
And, retention period and stop phase place, utilizing setting apparatus 5 to become input as weaving condition may be also passable.
The present invention can use the whole electric shedding apparatus 1 at loom.In the use of reality, as required in the drive circuit of motor 3 or rotating part load sensor is installed, and, the control device of not shown loom, when loom turns round (in weaving), measure the load of motor 3, and, when the load of measuring surpasses the load of being obtained by calculation by the essential factor of machinery etc., then send abnormal signal.Thus, can find the fault at the machinery of electric shedding apparatus 1 of loom rapidly, and also convenient in management.
