For example, in shedding motion 37, the binding of the driving shaft that also can be by removing open driving part 38 and the main shaft of loom 10, and make the actuator action of hydraulic cylinder etc., formation can make each heald frame 18 be in the remain silent expansion mechanism of state of split shed.Open driving part 38 is in the running of loom 10, and the main shaft 42 of the driving shaft of open driving part 38 and loom 10 links, and by the rotation of main shaft 42, each brown frame 18 is moved up and down.In addition, open driving part 38 is when the stopping of loom 10, command signal S8 according to the expansion instruction of exporting from main control unit 50, for the thick and thin places of finishing as the expansion action that prevents moves, make described actuator action, thereby make brown frame 18 knee-actions, so that Warp opening is positioned at the position that becomes split shed.Also can replace, by being configured in the clutch between driving shaft and the main shaft and can constituting equal engagement positions with the motor that driving shaft links, when accepting the expansion instruction, after becoming dissengaged positions by the connecting state that makes described clutch and main shaft 40, make the driving shaft rotation by described motor, carry out the expansion action.
Main shaft drives portion 76 controls the output shaft of Spindle Motor 40 and the rotation of main shaft 42 according to command signal S8 and rotation torque signal S9 from main control unit 50 outputs.
In more detail, main shaft drives portion 76 is in the specified time limit from the running beginning, according to preventing thick and thin places action and from command signal S7, starting torque signal, the starting torque conversion instruction of main control unit 50 outputs in order to finish, make the output shaft and main shaft 42 rotations of Spindle Motor 40 with high output torque, and the rotary speed with main shaft 42 becomes the high speed rotary speed at short notice, and reed 20 is beaten up.After the rotary speed of main shaft 42 reached the predetermined timing of normal rotary speed, main shaft drives portion 76 eased down to the moment of torsion of main shaft 42 and keeps the necessary moment of torsion that runs well.Main shaft drives portion 76 so finishes a series of drive controlling.
In addition, main shaft drives portion 76 stops by the rotation of closing the output shaft that makes Spindle Motor 40 from the output of the running command signal S1 of main control unit 50 outputs when the stopping of loom 10.Main shaft drives portion 76 is when the reversing of the crawl of loom 10, according to crawl signal S2 or the reversing alarm S3 from main control unit 50 outputs, in the rotation corresponding to the output shaft of the direction of rotation driven at low speed Spindle Motor 40 of crawl signal S2 or reversing alarm S3.
When change loom 10 when knitting the fabric semi-finished product of system, the operator carries out the last machine operation of loom 10, simultaneously will be corresponding to the board condition enactment of new fabric in the setting apparatus of loom 10.At this moment, also set the operating state that prevents the thick and thin places action as a link operator who sets.Fig. 3 represents to begin a series of processes that the system of knitting turns round from being input to of board condition.
At first, the operator operates the touch panel 56 of determining the loader of device 54 as setting value, weave cotton cloth 26 fabric condition (ST101) of input.An example such as Fig. 4 and shown in Figure 5 of the picture 80 of the touch panel 56 of this moment.
On Fig. 4, as a plurality of projects of the relevant warp thread 12 of relevant information of weaving cotton cloth with and the display field of setting value be presented at respectively on the left field A of picture 80 of touch panel 56.And the numerical key that is used for input value is presented at the right side area B of Fig. 4.Illustrated example represents, the operator at first touch area A " denting width " and numerical key is presented on the picture 80, use the numerical key that shows will import the state of " denting width " numerical value.
Fig. 5 is presented at the state of input " 190 " conduct " denting width " value on Fig. 4.And, on the left field A of the information that shows relevant warp thread 12, information as the warp thread 12 that becomes the basis that cover factor calculates, show that having imported " total radical " respectively is that " 10000 " root, " thickness " are the state of " a 40 " yarn, show that simultaneously selecting to have imported " thickness unit " respectively is the state of " cotton yarn " for " yarn made in Great Britain ", " kind ".
In addition, loom in recent years possesses the function of control through the rotation amount of axle 14, make as the detected load that acts on rear roller of warp tension, and detected warp tension maintains the regulation tension value.Therefore, also can automatically determine the tension force setting value of warp thread for example with the information of the described parameter of listing as relevant warp thread 12.More specifically, can calculate the tension force setting value by the total radical of unit tension K1 * warp thread * correction factor K2 that tension force sets value each root warp thread of S=, correction factor K2 selects according to fabric kind described later, fabric tissue or cover factor in addition, thereby can calculate the tension force setting value as mentioned above.
On the zone C of Fig. 5 upper left side, information as the weft yarn 24 of the relevant information of weaving cotton cloth, show that input " thickness " respectively is the state of " a 40 " yarn, show that simultaneously selecting input " thickness unit " respectively is the state of " 50 " root/inch for " yarn made in Great Britain ", " density of beating up ".
On the region D of Fig. 5 lower-left side, show that selecting input relevant respectively is that " 1/1 (plain weave) ", " fabric name " are the state of " spun yarn is general " as weave cotton cloth the fabric tissue of information or " the fabric tissue " of fabric kind of information.Demonstration on relevant such touch panel 56 and a series of processing of input are carried out according to the programme-control touch panel 56 that is stored in the memory 60 by central calculation processing apparatus 62.
As shown in Figure 5, the operator presses the button B1 (ST102) of picture 80 " preventing the thick and thin places automatic setting " after utilizing the relevant information of weaving cotton cloth of touch panel 56 inputs as described above.
With regard to touch panel 56, when pressing the button of " preventing the thick and thin places automatic setting ", input information that central authorities' calculation processing apparatus 62 is hereto imported from database 58 usefulness and mathematical formulae described later calculate represents that weft yarn inweaves the cover factor of situation, and retrieves the setting value (ST103) of each setting item corresponding to the cover factor of calculating.
Therefore, the setting value of the set condition that prevents the thick and thin places action of relevant input information of weaving cotton cloth is retrieved and determined to be suitable for to central authorities' calculation processing apparatus 62, and be shown in as shown in Figure 6 on the picture 80 of touch panel 56, simultaneously by port 64 to main control unit 50, warp let-off controller 52 and batch controller 74 output (ST104).
Fig. 6 is in described step ST104, and the operating state of determining automatically that prevents the thick and thin places action is shown in example on the picture 80, is illustrated in before loom 10 entrys into service, drives the example through the set amount of the recoil motion of axle 14 or cloth beam 28 rotations.
When pressing when being shown in " output " button of the display key on the picture 80 or " batching " button, be shown on the area E corresponding to the recoil amount of the button of pressing.Fig. 6 has shown the picture 80 of the touch panel 56 when pressing " output " button.
Shown " recoil patterns " expression of the picture 80 of touch panel 56 selects to depend on " the time control " of down time, and shows that selecting to import down time is " 5 " minute.In addition, the operation of touch panel 56 that also can be by the operator is irrespectively selected recoil pattern with same recoil amount control with down time.
Here, as shown in Figure 7, so-called down time is represented the switching period of the time control of recoil motion, in more detail, down time about the recoil amount, as shown in Figure 7, during assigning to from for example down time " 0 " that setting-up time " 5 " divides, according to setting value determined function by reversing amount 1 and reversing amount 2 and down time, produce the recoil reversing amount of increase corresponding to the increase of down time, and after down time was through 5 minutes, irrespectively produce the recoil reversing amount of reversing amount 2 with down time.But, also can consider to increase recoil reversing amount by stages by each down time.In addition, also identical therewith about the just commentaries on classics amount that recoils.
" just commentaries on classics amounts " and " reversing amount " expression recoil motion that the picture 80 of touch panel 56 is shown, to throw a spear with picking be the just commentaries on classics amount and the reversing amount of benchmark.
In addition,, also have following function, that is, stop the platform reason by each setting apparatus is set the recoil amount independently about recoil motion, and take place in the running according to loom 10 stop the platform reason, select the function of corresponding recoil amount.With regard to illustrated example, the operator can set and stop the latitude time (take place spray disconnected etc.), APR time (the picking mistake is removed the weft device action automatically) and menelipsis independently to setting apparatus.
After the operating state of so determining to prevent the thick and thin places action, the operator carries out the test weaving running as required, and the effect that prevents the thick and thin places action of investigating described definite setting value promptly has or not the generation (ST105) of thick and thin places.
The operator is when thick and thin places takes place in the result who judges test weaving, by operating the retrieval setting value on touch panel shown in Figure 6 56 pictures 80, the value that will revise for the described setting value of determining automatically as new setting value to as corresponding to the warp let-off controller 52 of drive circuit or batch controller 74 outputs.
The operator after the setting of carrying out board condition in addition or adjustment etc., presses running button 66 except carrying out the setting that prevents thick and thin places device 78, makes loom 10 begin to knit system running (ST106).
Table 1 expression is used to determine to prevent the example of database 58 of the operating state of thick and thin places device 78.

Table 1 shows the cover factor value corresponding to relevant information of weaving cotton cloth, and prevents the operating state of thick and thin places device 78.
If illustrate in greater detail table 1, then it is that cover factor is divided into 4 grades, as the example of database 58 by each one of the records of 4 differentiations of described cover factor or the above operating state that prevents the thick and thin places action.Even cover factor difference for example also can or be batched the recoil motion of controller 74 as the opening expansion of open driving part 38, operating state is set for identical, also can with a plurality of operating states at least one or more than set difference for.
At this, about loom 10 prevent thick and thin places action, action for example as follows is arranged, only as with reference to the operating state that shows corresponding to cover factor, below, the project of the operating state of database of descriptions 58 and the relation of cover factor.
[opening control]
So-called opening control is when instigating on-stream loom 10 to stop, and makes in the rotation of main shaft 42 inertia through axle 14 or cloth beam 28 rotation ormal weights, makes the action of the position displacement forwards of fell 22.By this action, can produce following effect: prevent the generation of the section of parking thereby reduce when the running that makes loom 10 stops, thereby or reduce warp tension and prevent that the warp thread of loom 10 in stopping from extending the effect of the generation of the thick and thin places that causes to loom 10 power of beating up during starts.
Database 58 constitutes the addendum modification (amount of dodging) and the cover factor CF of the position of attonity, fell 22 in a systematic manner by each device.
[inching feed/reversing is returned]
After so-called inching feed/reversing is returned the running that is meant loom 10 and is stopped, the operator is for example in order to repair broken yarn when crawl operation or reversing operation loom, reversing of main shaft 42 crawls and angle by stipulating, at this moment, make through the rotation of axle 14 or cloth beam 28 to positive veer or reverses direction rotation ormal weight.The operator is carrying out crawl when reversing, and main control unit 50 makes through axle 14 or 28 forward or reverse of cloth beam corresponding to predefined one amount of throwing a spear, and makes the position of fell 22 advance or retreat, thereby the position of fell 22 is kept in position.
Database 58 constitutes the addendum modification (amount of feeding amount of returning) and the cover factor CF of the position of fell 22 in a systematic manner by each device.
[expansion of shedding motion]
The expansion of so-called shedding motion 37 be meant the running from loom 10 stop to repair to the operator stop the platform reason during, prevent thick and thin places device 78 remove brown frame 18 and loom 10 main shaft 48 synchronously, for example, actuator by not shown hydraulic cylinder etc. drives brown frame, makes the opening of warp thread 12 become the action that split shed is remained silent.
For example, when loom 10 system of knitting twill, satin weave etc., intersect regularly even have, any brown frame 18 all is in upper-lower position.Therefore, when loom 10 is in the state that stops for a long time, warp thread 12 and weave cotton cloth and 26 be in the state that forms opening, fell 22 moves to its opening direction (moving direction of warp thread 12 is a fore-and-aft direction).In order to prevent the generation of such thick and thin places, carry out the action of the expansion of shedding motion 37.
Carry out the expansion action of shedding motion 37, can prevent warp thread 12 elongation or because of about the position of the fell that inhomogeneous tension force produced 22 of warp thread 12 move.
Database 58 constitutes the having or not or the opening amount and the cover factor CF of brown frame 18 of expansion action of shedding motion 37 in a systematic manner.
[recoil]
Before loom 10 startings, make through axle 14 or cloth beam 28 and only rotate ormal weight to positive veer or reverses direction, make of the fore-and-aft direction displacement of the position of fell 22 to the warp thread direction of travel.With this, can compensate when making loom 10 starting the too not enough part of the power of beating up that the loom main shaft of specified time limit is in the transition rotation status.
Database 58 constitutes order, rotation amount, rotary speed and the cover factor CF that is just changeing and reversing in a systematic manner by each device.
In addition, about described " opening control ", " inching feed/reversing is returned ", " recoil ", it is standard that the setting value T that derives from database 58 throws a spear with picking.Therefore, in fact warp let-off controller 52 or batch controller 74 based on beat up value and this setting value of coefficient etc. of density or machinery of weft yarn, from warp thread 12 or 26 the movable length of weaving cotton cloth, the drive amount that calculates warp let-off motor 34 respectively or batch motor 46 drives through axle 14 or cloth beam 28 rotations.But being stored in that setting value in the database 58 there is no need to throw a spear with picking is benchmark, also can be used as warp thread or the movable length of weaving cotton cloth is stored.
[starting method]
The operator for example selects one from following (A), (B) or the order (C), makes loom 10 startings.
(A) common starting method
At first, because of after stopping the stopping of platform reason, make main shaft 42 low speed reverse the standby angle (300 °) that is in the state of remaining silent to Warp opening at loom 10.
Stop the platform reason in order to eliminate, the operator carries out crawl or reversing and carries out necessity reparation of wrong yarn removing of picking or broken yarn repairing etc., makes main shaft 42 be positioned at standby angle (300 °).Then, make Spindle Motor 40 startings by the running button of operating loom 10, the angle θ of main shaft 42 begins picking immediately from beating up after passing through 0 °.
(B) back starting (sky is played moving)
For stopping the platform reason and be in the standby angle (300 °) of the state of remaining silent and then repair and stop making main shaft 42 be positioned at standby angle (300 °) after the platform reason, identical with the common starting method of described (A) to main shaft 42 is reversed to Warp opening from loom 10 takes place.Yet,, at first make the starting angle of main shaft 42 from the reversing of standby angle (300 °) low speed to regulation by the running button of operation loom 10.
(C) 60 ° of methods of starting
Stop the platform reason from generation and stop to loom 10, identical with described (A), (B) each starting method.But difference is to beat up in order to avoid, and makes main shaft 42 be made to standby angle (60 °).
Then, the operator stops the platform reason in order to eliminate, carry out crawl or reversing operation after, carry out necessary reparation, make main shaft 42 be positioned at standby angle (60 °).Then, by the running push button start Spindle Motor 40 of operation loom 10, begin picking simultaneously immediately.
Database 58 constitutes selectable starting method and cover factor CF in a systematic manner.And database 58 also can constitute (reversing stop angle, sky are beaten number of pick) during the selection mode of starting method, empty the beating, standby angle or described predetermined angular etc. one or with upper angle timing setting value, cover factor CF in a systematic manner.
[single picking]
After operation running button 66, be in to warp thread 12 near the predetermined angular (120～200 °) of open state with the low speed crawl, make then after weft insertion device action and weft yarn 24 of picking, make main shaft 42 crawls arrive the standby angle.Subsequently, the selection mode according to described starting method starts Spindle Motor 40 and begins picking.
Database 58 constitutes in a systematic manner and has or not single picking movement and cover factor CF.
[starting torque]
Starting torque is meant the starting torque when starting Spindle Motor 40 behind operation running button, can change starting torque by selection to the size of the electric power (voltage) of Spindle Motor 40 supplies.When producing light filling bar (weft count chap phenomenon), when starting loom 10 with than high usually moment of torsion rotation and the moment of torsion that beats up when improving starting.Then from the viewpoint of conservation of power, again it is suppressed for common moment of torsion and make it continue rotation.
Database 58 constitutes starting torque size degree and cover factor CF in a systematic manner.
[starting torque switching controls]
The starting torque switching controls be meant in described " starting torque " control, after Spindle Motor 40 starting, return the period of described common moment of torsion.Making starting torque return period of described normal moment of torsion by postpone setting, utilizing and described " starting torque " control the beat reed power of effect switching Spindle Motor 40 after starting that multiplies each other.
Database 58 constitutes switching timing (comprising number of pick) and the cover factor CF that turns back to normal moment of torsion from high moment of torsion in a systematic manner.Here, switching timing is a benchmark with elapsed time or main shaft angle from the benchmark angle preferably.
About preventing the thick and thin places action,, also can make up with described action so long as at least one in described or above getting final product can be adopted described action in addition in addition.In addition, using a plurality ofly when preventing thick and thin places device 78, a plurality ofly preventing that the operating state of thick and thin places device 78 also can be different.
Here, the expression yarn cover factor CF that inweaves situation can be expressed as: the cover factor CFp of the cover factor CFw+ weft yarn of cover factor CF=warp thread.Wherein, the cover factor CFp=C/ √ D of the cover factor CFw=A of warp thread * 2.54/ √ B, weft yarn.Become each parameter of the input information on the basis that cover factor calculates, promptly the parameter A representation unit is knitted the warp thread radical of width of cloth length, the thickness that B parameter is represented warp thread (yarn), parameters C and is represented to set beat up density, D and represent the thickness (yarn) of weft yarn 24.
Specifically, parameter A is to obtain with the total radical/denting width of warp thread.Therefore, parameter A can calculate according to total radical and the denting width gauge of conduct about the warp thread of the input information of described warp thread.
Each parameter A, B, C, the D on the basis the when operator calculates cover factor by becoming import, and obtain cover factor by the central calculation processing apparatus 62 that constitutes the definite device of setting value from the numerical value of input.But, also can replace such calculating, consider that the operator oneself calculates the cover factor of obtaining by touch panel 56 direct inputs.
Here, cover factor is that yarn is inweaved the parameter that situation (degree) quantizes.In other words, the difficulty or ease of beating up of cover factor original state ground reflection weft yarn 24.
So-called thick and thin places (be the present invention as object with loom stop and the stop segment that producing), be the even phenomenons of weft yarn 24 density unevennesses.To this, cover factor inweaves situation (degree) with yarn and quantizes.In other words, the difficulty or ease of beating up of cover factor original state ground reflection weft yarn 24.
According to inventors' research, the fabric of density low (the CF value is little) is the final density of knitting that will be formed by 24 once beating-ups of the weft yarn of picking.And the fabric of high density (CF value big) is will to be beaten up for more than 24 time by the weft yarn of picking and the final density of knitting that forms.
Inventors find cover factor and the relevance of beating up that is used to the weft count that obtains to stipulate, and clear and definite in operating state that prevents thick and thin places device 78 and the dependency relation that shows between the cover factor CF that yarn inweaves situation.
In view of the above, be suitable for the information fabric specification, that prevent the operating state of thick and thin places device 78 as being used to set, it is very desirable, rational being conceived to cover factor CF, promptly setting the operating state that prevents thick and thin places device 78 according to the value (in other words being the complexity of weft yarn 24 beating up property) of cover factor CF.
Like this, according to the information of the relevant specification of weaving cotton cloth of input from the setting value that prevent operating state that thick and thin places move of database 58 retrieval corresponding to the information of the relevant specification of weaving cotton cloth, the operating state that prevents the thick and thin places action of deterministic retrieval is also automatically set, thick and thin places moves, the cloth fell that prevents as hope is moved, improve the moment of torsion that beats up, repeatedly beat up.Even being the operator of lack of experience, supposition also can prevent the thick and thin places action to consider that operating state that yarn inweaves situation is finished, thus the fabric of production high-quality expeditiously.
It is following definite that above setting value determines that device 54 can carry out.
For example, information as the relevant specification of weaving cotton cloth, except about the described cover factor, also has the kind (1/1 plain weave, 2/1,3/1... twill, 4/1,5/1... satin weave, fancy fabric, multi-arm line etc.) of fabric kind (spun yarn is general, base fabric, woolen knitwear etc.), fabric tissue.
Therefore, for the formation of the architectonical of cover factor shown in the table 1 and operating state, as shown in table 2, database 58 also can be added fabric kind or fabric tissue and architectonical ground constitutes.In addition, for the formation of the architectonical of table 1, as the information of the relevant specification of weaving cotton cloth, self-evident so long as any one in described two, preferably both sides get final product.
[table 2]
Zero: action on, *: action off, a1 ... 12 expression numerical value (omitting concrete numerical value, intersymbol magnitude relationship), G1～G2 represents the kind of starting method.
When being in the time of to retrieve the setting value T consistent with this information according to result about the DIALOG information retrieval database DIALOG 58 of the specification of weaving cotton cloth, central authorities' calculation processing apparatus 62 also can be retrieved once more with the condition of approximate this information, and exports the setting value T that calculates by insertion from a plurality of operating states that retrieve.
Central authorities' calculation processing apparatus 62 also can replace and utilizes database 58, and in advance the information of the relevant specification of weaving cotton cloth is stored in the memory 60, by the information of the relevant specification of weaving cotton cloth is gone out to set value T as the function calculation of parameter.
Also can replace with the setting apparatus dual-purpose of loom 10 be set up, prevent that thick and thin places device 78 is provided with setting value and determines device 54 and be exclusively used in.
In addition, setting value determines that device 54 also can be made of many looms 10 public microcomputers.At this moment, for example the setting apparatus of each loom 10 and microcomputer can couple together communicatedly by wired or wireless network.Also can be on the display part of the setting apparatus of loom 10 the display setting value determine the output information of device 54 outputs.
Setting value determines that device 54 also can be made of the computer of being located at loom 10 caretaker rooms.At this moment, on paper, the operator can set and prevent thick and thin places device 78 according to the printout information on the output paper the definite device 54 of setting value with the output information printout.
Described embodiment also can have following modification.
Though store cover factor and prevent that the database 58 of the setting value of the operating state that thick and thin places moves from being provided by loom manufacturer one side in advance, but preferably user such as the manufacturer or the factory of weaving cotton cloth can revise database according to knitting system actual achievement etc. subsequently, or the structure of the insufficient section in supplemental data storehouse.
Loom about applicable object of the present invention, beat up density, fabric tissues etc. of weft yarn kind, weft yarn are knitted the system condition and are not limited in knitting system running and knit the loom of system with single condition, for example also be applicable to according to the rotation of loom main shaft switch described any one knit the loom of system condition.At this moment, the input information of the relevant specification of also can be in advance switching of weaving cotton cloth to throw a spear by each picking, throw a spear setting corresponding to the operating state that prevents the thick and thin places action of knitting the system condition by each picking in advance, when loom stops, carrying out the corresponding thick and thin places that prevents and move.
The cover factor CF of present embodiment will become the result's of two basic cover factor additions value, it is result's the value of the cover factor CFp addition of the cover factor CFw of warp thread and weft yarn, but also can for example be conceived to described become the basis two cover factors in any one (promptly, just the cover factor CFw of warp thread or just the cover factor CFp of weft yarn), and determine to prevent the operating state of thick and thin places action in view of the above.
The present invention is not limited to described embodiment, only otherwise breaking away from its aim can have various changes.
