The structure of above-mentioned yarn selecting arrangement 7 is identical with the structure of above-mentioned patent documentation 1 disclosed yarn selecting arrangement, below with reference to Fig. 3 or Fig. 4 simple declaration.This yarn selecting arrangement 7 possess with the warp thread Y, the Y that supply with ... the corresponding setting of quantity (6) 6 thread- carriers 17,17 ... make these 6 thread-carriers 17 can reverse up and down individually, diagram abridged driving cylinder (cylinder), the suction nozzle (magnetic-attraction element) that can attract the diagram of warp thread Y to dispense can overcome the maintenance roller 18 that line end that this attraction keeps warp thread Y makes its standby.

Each thread-carrier 17 is designed to cylindric, and makes its inside can pass the warp thread Y of supply.And each of 6 thread-carriers 17 can be in conversion between lifting position (chosen position) and down position (select to remove the position or make a concession the position) independently under the driving of above-mentioned driving cylinder.

And above-mentioned knotter 8 is arranged on the downstream near yarn selecting arrangement 7.Because the structure of this knotter 8 is general structure, can adopt for example above-mentioned patent documentation 1 disclosed well-known knotter etc., therefore omit its detailed description.

The yarn switching mechanism 3 (yarn selecting arrangement 7 and knotter 8) that the following describes with this structure carries out the action that warp thread Y switches.As shown in Figure 2, be imported into 6 warp thread Y, Y in the yarn selecting arrangement 7 of each yarn switching mechanism 3 ... be punctured in the yarn selecting arrangement 7 the above-mentioned thread- carrier 17,17 that is provided with ... in, insert 1 in each thread-carrier 17.And yarn selecting arrangement 7 is selected one or more in 6 yarns, controls above-mentioned driving cylinder and makes the corresponding thread-carrier 17 of the warp thread Y that chooses with this be positioned at the chosen position of upside, makes the thread-carrier 17 of not selected warp thread Y be positioned at the position of dodging of downside simultaneously.

Here, when thread-carrier 17 was switched to chosen position, the end of a thread that is imported into the warp thread Y in this thread-carrier 17 can be submitted to the knotter 8 in downstream.And be positioned at when dodging the position when thread-carrier 17, the end of a thread of warp thread Y is not submitted to knotter 8, is maintained to keep standby on the roller 18.

In the yarn switching mechanism 3 of this structure, supply with beam warping when the warp thread Y of axle 11 switches to the warp thread Y of another kind of color (or another yarn kind) when choosing at that time, drive above-mentioned driving cylinder, the thread-carrier 17 of the warp thread Y that is equivalent to supply with is at that time descended, be in and dodge the position, and make the thread-carrier 17 of the warp thread Y that guiding newly chooses rise to chosen position from dodging the position.And, cut off at that time warp thread Y with knotter 8, and will this cut the end of a thread (beam warping is through the end of a thread of axle 11 sides) tie a knot with the end of a thread of new warp thread Y.In addition, the end of a thread of not selected warp thread Y (the end of a thread of yarn feeding package 5 sides) is automatically by keeping roller 18 to remain in holding state, in order to select this warp thread Y once more afterwards.So, can switch the color (or yarn kind) of supply beam warping through the warp thread Y of axle 11.

By above-mentioned yarn selecting arrangement 7 choose, from above-mentioned 64 yarn switching mechanisms 3, draw respectively amount to 64 warp thread Y, Y ... be fed to fabric width as shown in Figure 1 and determine reed 13.And, respectively the spool rack 10b from opposite side draw, by yarn ConvertBox 12,12 ... between amount to 84 warp thread Y, Y ... also be sent to fabric width as shown in Figure 1 and determine reed 13.Then, because of determine by fabric width that reed 13 is arranged in parallel amount to 148 warp thread Y, Y ... along the length that direction shown in the thick-line arrow of Fig. 1 is reeled and stipulated, form beam warping through axle 11.

In addition, above-mentioned beam warper 2 possesses rotation and drives the motor (motor) 19 of above-mentioned beam warping through axle 11, and for example pulse motor or servomotor constitute this motor 19 by the motor that can control angle.This motor 19 links to each other with the controller (warping machines controller) 20 of beam warper 2, by the rotation of the above-mentioned motor 19 of this warping machines controller 20 controls with stop.And warping machines controller 20 links to each other with the upper system controller (control device) 21 of the whole beam warping of control system 1.

When warp thread Y, Y ... the length of the regulation of reeling forms beam warping when axle 11, takes off this beam warping through axle 11 from beam warper 2, carry out repeatedly said process reel new warp thread Y, Y ..., form beam warping through axle 11.In this example, form 2 beam warpings through axle 11 with beam warping system shown in Figure 11.Then in next process from comprise above-mentioned 2 beam warpings through a plurality of beam warpings of axle through axle 11, draw many warp thread Y, Y ..., carry out starching (starching process) in the time of merging.

In above-mentioned starching process, dispose a plurality of above-mentioned beam warpings through axle 11 at upstream side as shown in Figure 5.In addition, for the purpose of simplifying the description, only represented among Fig. 5 that 10 beam warpings are through axle.And, in this example, only have 2 beam warpings that added asterisk (*) among Fig. 5 to form through the beam warping system 1 of axle 11 usefulness Fig. 1.Remaining beam warping through axle 11 for the beam warping of reeling with common beam warper (not switching warp thread Y) through axle, in axle 11,148 warp thread Y all are white at these remaining beam warpings.

In Fig. 5, from each beam warping through axle 11 draw respectively 148 warp thread Y, Y ... after, with warp thread Y, Y ... merge, successively proper alignment.Then warp thread Y, Y ... by a plurality of guide roller 24 guide properlies, on immersing, after stock tank 25 starchings, be wound up into weaving on axle 26.So, form warp thread Y, the Y about 4000～5000 that for example reeled ... weaving supply with the fabrication processes of back through axle 26.

And, the beam warping system 1 of this example as shown in Figure 1, said system controller 21 adopts and is electrically connected with above-mentioned 64 yarn switching mechanisms 3 respectively (only represented among Fig. 1 to wherein a part of yarn switching mechanism 3 input signals), can control the structure of this yarn switching mechanism 3 separately.Though not expression in detail among the figure, system controller 21 in this example adopts well-known micro computer formula structure, not only possess as the CPU of arithmetic element with as the ROM or the RAM of memory cell, and possess to the output unit of warping machines controller 20 or above-mentioned yarn switching mechanism 3 output control signals etc.

Said system controller 21 preestablishes the information of above-mentioned beam warping through the coiling length of axle 11, and this length information is stored in the memory cell such as RAM.So system controller 21 calculates the anglec of rotation of the beam warping of the length that is equivalent to this storage through axle 11, send instruction to warping machines controller 20, drive beam warping through this anglec of rotation of 11 rotations of axle.Accepted the motor 19 of the above-mentioned beam warper 2 of warping machines controller 20 controls of this instruction, made the anglec of rotation of its rotation appointment.So, can make the anglec of rotation of beam warping through axle 11 rotation regulations, the 148 warp thread Y that reeled simultaneously, the beam warping that forms specific length is through axle 11.

And, system controller 21 adopts such structure: can be the information (handover information) of the warp thread Y of the cut-out place of each root warp thread Y input among 64 warp thread Y that pass through above-mentioned yarn switching mechanism 3 of a beam warping in the warp thread Y of axle 11 (148) and setting warp thread Y and cut-off part according to the decorative pattern after the weaving, this set information be stored in the memory cell such as RAM.

If for the example of an above-mentioned handover information, handover information is such information: when reeling beginning, No. 1～No. 32 warp thread Y all is blue; Leaving coiling starting point 180m place, No. 6 and No. 32 warp thread Y are being switched to yellow; Leaving coiling starting point 230m place, No. 6 and No. 25 warp thread are being switched to redness.In addition, the numbering of warp thread Y (No. 1～No. 64) in this example with numbering (No. 1～No. 64, the #1～#64) corresponding of yarn switching mechanism 3.And, below will be arranged on spool rack 10b one side 84 yarn feeding packages 5,5 ... all be that white illustrates.

In the above description, system controller 21 adopts such structure: make beam warping be equivalent to starting point after the anglec of rotation of the distance of switching place through axle 11 rotations according to above-mentioned handover information, select only to make and the corresponding yarn switching mechanism 3 of warp thread Y (yarn selecting arrangement 7 and the knotter 8) action that needs to switch, switch warp thread Y.

The following describes the concrete example of controlling according to the example of above-mentioned handover information.At first, system controller 21 is given No. 1～No. 64 yarn switching mechanism 3 transmission information, and No. 1～No. 64 warp thread Y all selects blue warp thread Y to supply with.Then, system controller 21 drives above-mentioned motor 19 by warping machines controller 20, begin warp thread Y is wound up into beam warping on axle 11, drive beam warping and be in up to the position of yarn switching mechanism 3 through axle 11 rotations and stop when being equivalent to leave starting point 180m place.Then, system controller 21 is given No. 6 and No. 32 yarn switching mechanisms 3 send the instruction of switching yarns, and No. 6 and No. 32 warp thread Y are changed over yellow warp thread Y from blueness.

In addition, the yarn switching mechanisms 3 beyond No. 6 and No. 32 do not carry out change action.That is, leave coiling starting point 180m place, only selecting No. 6 and No. 32 yarn switching mechanism 3 actions in 64 yarn switching mechanisms 3.But this is because the cause that the above-mentioned yarn handover information of this content is set, and is for example setting under the situation of order for the handover information that No. 1 to No. 64 warp thread Y all switched to yellow warp thread No. 1 to No. 64 all action of these 64 yarn switching mechanisms 3.

After finishing switching, drive motor 19 once more, drive beam warping specifically and make yarn switching mechanism 3 be positioned to leave the anglec of rotation at coiling starting point 230m place that it is stopped through axle 11 rotation.System controller 21 sends the yarn switching commands to No. 6 and No. 25 yarn switching mechanisms 3 then, makes its action selectively, and this yarn switching mechanism 3 is responsible for No. 6 and No. 25 warp thread Y switch to red warp thread Y.

By carrying out such control, can in the way of axle 11, change 64 color or yarn kinds in the longitudinal direction that are wound in 148 warp thread of this beam warping on axle 11 at the beam warping of reeling, carry out warping simultaneously, can realize diversified decorative pattern.For example, can realize be respectively indigo plant in vain blue white indigo plant in vain through the weaving that axle 11 forms through axle 26 by merging above-mentioned beam warping ... such striped, perhaps the yellowish-white in vain indigo plant of indigo plant in vain ... such striped, perhaps indigo plant is red in vain white in vain red ... such striped.

And, compare with patent documentation 1 disclosed structure, owing to can not need to form the set-up procedure of the special yarn feeding package that equates with the radical of many warp thread, therefore can simplify the warping process significantly.

And in this example, owing to determine switching position by the control beam warping through the anglec of rotation of axle 11, therefore the deviation between the switching position of beam warping warp thread Y in axle 11 is little, can positively show the decorative pattern of wanting.And, owing to be, therefore do not need the device of special measurement length by the structure of beam warping through the rotation angle measurement length of the motor 19 of axle 11, can simplified structure.

As mentioned above, the beam warping system 1 of this example comprise spool rack 10a, the 10b of the yarn feeding package 5 that can lay a plurality of supply warp thread Y and many warp thread Y, the Y that will supply with by this spool rack 10a, 10b simultaneously ... be wound up into the beam warper 2 of warping on axle 11.And, the yarn switching mechanism 3 of the knotter 8 that a plurality of warp thread Y that possess yarn selecting arrangement 7 and this yarn selecting arrangement 7 is chosen tie a knot is set in the yarn path that forms between spool rack (above-mentioned the 1st spool rack 10a) and above-mentioned beam warper 2.And the 1st spool rack 10a adopts the structure that can lay the package group 4 who is made of the different a plurality of above-mentioned yarn feeding package 5 of color with above-mentioned yarn switching mechanism 3 correspondingly.And yarn selecting arrangement 7 that adopt to give above-mentioned yarn switching mechanism 3 supply with from above-mentioned package group 4 separate the warp thread group Y, the Y that relax ..., simultaneously this yarn selecting arrangement 7 from supply with the warp thread group Y, the Y that come ... in select a structure of supplying with above-mentioned warping through axle 11 at least.

Thus and since can be enough yarn switching mechanism 3 switch warp thread Y, so change decorative pattern etc. easily and can tackle flexibly, can realize the beam warping system 1 that versatility is high.

And the quantity (64) that is provided with of above-mentioned yarn switching mechanism 3 is lacked than the radical that is wound up into the warp thread Y of above-mentioned warping on axle 11 simultaneously (148) in the beam warping system 1 of this example.

In other words, be wound up into simultaneously 148 piece warp thread Y, the Ys of above-mentioned beam warping on axle 11 ... in a part promptly the yarn selecting arrangement 7 of the above-mentioned yarn switching mechanism 3 of 64 velamens choose and supply with, supply with without above-mentioned yarn switching mechanism 3 from above-mentioned yarn feeding package 5 for remaining 84.

Therefore, do not need for form beam warping through all warp thread Y, the Y of axle 11 ... yarn switching mechanism 3 is set, and the yarn switching mechanism 3 that necessary amount only need be set as required is just passable, so can simplified structure, and can dwindle the space is set.

And, the beam warping system 1 of this example possesses at the above-mentioned warp thread Y with specific length and is wound up into the run that makes a plurality of above-mentioned yarn switching mechanism 3 whole or selected in the way of above-mentioned warping on axle 11, changes and is sent to the system controller 21 that above-mentioned warping is controlled in this wise through the selection of the warp thread Y of axle 11.

Therefore, can in the way of axle 11, change the color of this warping of formation, therefore can realize extremely various decorative pattern in the coiling warping through the warp thread Y of axle 11.And, since be with many warp thread Y, Y ... be wound up into beam warping together on axle 11, and the independent on the way and while changes the structure of the color of each root warp thread Y concurrently, therefore is not easy to produce the deviation of the position in the change place between the warp thread Y, can obtain good decorative pattern.And,, therefore can reduce time, operation quantity and cost etc. significantly owing to can omit the such set-up procedure that is rolled into package of patent documentation 1.And, by reeling simultaneously and changing warp thread Y concurrently simultaneously, can reduce beam warping warp thread Y in axle 11 and change the site error in place, can reduce decorative pattern messy or disorderly of appearance.

In addition because it is little to change the site error in place as mentioned above, so the beam warping system 1 of this example freely the warping number is meter long to the long warp thread of thousands of rice, can realize the beam warping that the free degree is high.

That is, the method for prior art patent document 1 position deviation in the change place of warp thread as mentioned above is big, and this position deviation goes up constantly accumulation along with continuing to be wound up into the warping drum, and the situation that produces the position deviation above 1 meter when finishing to reeling is many.Therefore, when the coiling that the short warp thread about with several meters is configured to the warping drum finishes near the end,, then almost do not remain the live part that can be used in fabrication processes if remove the part of having to discard that causes because of the position deviation of switching the place.Therefore, the method for patent documentation 1 has to adopt the warp thread that will relatively lack to be configured to the coiling starting end of warping drum, long warp thread is configured to reel finishes to hold such warp thread to arrange.

In this, even therefore this example is configured to short warp thread Y warping easily and finishes to hold through the coiling of axle 11 because beam warping also can dwindle the deviation between the change point of warp thread Y near the coiling terminals through axle 11.Therefore, owing to can freely design warping through axle 11 layout of warp thread Y in the longitudinal direction, so can reduce the waste of warp thread Y, and can improve the production efficiency of subsequent handling.

And in this example, above-mentioned beam warper 2 possesses can control above-mentioned warping through the angle of axle 11 and drive the motor 19 of its rotation.And said system controller 21 adopts and can make above-mentioned warping through the angle of axle 11 rotations corresponding to predefined switching place, makes the whole or selected run of above-mentioned yarn switching mechanism 3 simultaneously, changes the structure of the selection of warp thread Y.

Thus, utilize a warping to determine the switching position of each warp thread through the anglec of rotation of axle 11.Therefore, can further reduce the deviation between the switching position of warping warp thread Y in axle 11, can not produce messyly etc. in the decorative pattern of wanting, can positively show.And,, therefore can make simple in structure owing to do not need the device of special measurement length.

And,, therefore can reduce and switch the absolute position deviation in place owing to utilize warping directly to locate through the anglec of rotation of axle 11.For example, though 2 warpings of having added asterisk (*) mark shown in Figure 5 change warp thread Y by beam warping system 1 according to identical handover information and reel through axle 11 in this example, but because deviation is little as mentioned above, even therefore picture makes 2 warpings lump together through axle 11 as shown in Figure 5, the position deviation of two warpings between the switching place between the warp thread Y of axle 11,11 is also little.As a result, can further positively reproduce the decorative pattern of wanting.

And this example carries out beam warping with following direction.From be placed in a plurality of yarn feeding packages 5,5 on spool rack 10a, the 10b ... supply with warp thread Y, they are wound up into beam warping simultaneously on axle 11.And, lay on the spool rack 10a of a side by have at least in the color of each package or the yarn kind equally different a plurality of yarn feeding packages 5,5 ... the package group 4 who constitutes.Will from this package group 4 separate the warp thread group Y, the Y that relax ... supply with the yarn selecting arrangement 7 with the corresponding one by one setting of each package group 4 respectively, each yarn selecting arrangement 7 from the warp thread group Y, the Y that supply with ... at least 1 warp thread Y of middle selection supplies with above-mentioned warping through axle 11.And, the knotter 8 that the yarn that this yarn selecting arrangement 7 is selected carries out joint is set correspondingly with this yarn selecting arrangement 7.

Thus, also can be easily and flexibly reply change decorative pattern etc., can provide versatility high beam warping method.

And, be wound up into simultaneously in the beam warping method of this example among 176 warp thread Y of above-mentioned beam warping on axle 11 a part promptly the yarn selecting arrangement 7 of the above-mentioned yarn switching mechanism 3 of 64 velamens choose and supply with, remaining 84 from above-mentioned yarn feeding package 5,5 ... supply with without above-mentioned yarn switching mechanism 3.

By such method can with the above-mentioned the same number that reduces yarn selecting arrangement 7 and knotter 8, can the control appliance cost.

And, the beam warping method of this example is wound up into the run that makes a plurality of above-mentioned yarn switching mechanism 3 whole or selected in the way of above-mentioned warping on axle 11 at the above-mentioned warp thread Y with specific length, changes and is sent to the selection of above-mentioned warping through the warp thread Y of axle 11.

Utilize this method, constitute the color of this warping, can realize extremely various decorative pattern through the warp thread Y of axle 11 by in the coiling way of axle 11, changing in warping.And, as mentioned above,, therefore can positively realize the decorative pattern of wanting owing to can dwindle the deviation of position in the switching place of warp thread Y.

Preferred example of the present invention more than has been described, but above-mentioned example also can be as for example change as follows.

No drum-type beam warper 2 shown in Figure 1 also can be altered to the drum-type beam warper of the friction-driven of utilizing contact drum.At this moment, adopt above-mentioned motor 19 to link to each other with drum, by this motor 19 by the above-mentioned warping of drum driving through axle 11 and control the structure of its angle.

Confirm that through the anglec of rotation of axle 11 structure of the coiling length of warp thread Y can be altered to by beam warping, possess in the beam warper 2 and be wound up into the turn-sensitive device that the warp thread Y of warping before on axle 11 contact the length measuring roller (rotary body) of rotation and detect the rotation of this length measuring roller, system controller 21 bases are from the coiling length of the signal affirmation warp thread Y of this turn-sensitive device.At this moment, owing to be the structure of position of determining the switching place of warp thread Y according to the signal of turn-sensitive device output, therefore can be accurately and positively determine the position of switching point can positively show the decorative pattern of wanting.

And, be the parallel cheese frame though in this example, make spool rack 10a, 10b, also can adopt other arrangement mode.And, both can adopt the structure that the 1st spool rack 10a and the 2nd spool rack 10b is comprehensively become a spool rack, also can adopt each spool rack 10a, 10b are cut apart the structure that is configured to a plurality of places.And the layout of spool rack 10a, 10b also is not limited to the layout shown in Fig. 3 etc.

And, though adopt 64 warp thread Y pictures being chosen and supply with by yarn switching mechanism 3 in whole 148 warp thread to be wound on the structure of warping as shown in Figure 1 through a plurality of places of the width of axle 11, but the warp thread Y shown in Fig. 1 etc. is arranged as an example, can be wound up into any position of warping through the width of axle 11.

Though above-mentioned example adopts knotter 8 as piecing devices, also can adopt other piecing devices such as connector to replace knotter 8.And, the tensioning apparatus of the tension force of regulating warp thread Y or thread-carrier etc. can also the appropriate location in the middle of the path of above-mentioned spool rack 10 or warp thread Y be set.

Though in above-mentioned example, be provided with 64 yarn switching mechanisms 3, both can have Duoed and also can lack than this than this.And, also can change over 148 the yarn switching mechanisms 3 identical with the radical that is wound up into the warp thread of beam warping on axle 11 (148), the structure that 148 warp thread Y can be switched are set.

And though constitute yarn switching mechanism 3 by yarn selecting arrangement 7 and knotter 8 in above-mentioned example, yarn switching mechanism 3 can also possess the yarn save set that can preserve warp thread Y.At this moment, owing to can reduce beam warping in axle 11 winding process in order to switch the time that warp thread Y stops to reel or to be zero, therefore can enhance productivity.

The warp thread Y that each yarn selecting arrangement 7 is chosen is not limited to 1.That is,, supply with 2 warp thread Y, Y through axle 11 then can for simultaneously beam warping if make 2 thread- carriers 17,17 in 6 thread-carriers of yarn selecting arrangement 7 be in chosen position.Thus, can realize diversified decorative pattern.

In the beam warper 21 beam warping through the number of the radical of the warp thread Y of axle 11, yarn switching mechanism 3 and constitute a package group 4 yarn feeding package 5,5 ... number be not limited to above-mentioned quantity, can suitably change according to the specification of beam warper 2.And, yarn feeding package 5,5 ... the color or the combination of yarn kind etc. be arbitrarily, can be according to decorative pattern of wanting to realize or feel, or only change color in the yarn of the same race, or only change the yarn kind of color of the same race, or change color and yarn kind simultaneously, can suitably select the switching of various yarns according to necessity.

The following describes the situation when use is of the present invention in the section warping system.

Background technology

As one of the beaming method prepared of weaving, we have known the section warping method.Warp thread is extracted and supplied with to this section warping method out from a plurality of yarn feeding packages (for example dozens of is to about hundreds of) that are placed on the spool rack, forms the 1st band (band) in the end of the bulging tapered side of the warping with taper winding face.That is, under the state that the axle with the warping drum tilts, the width little layer of a width of reeling than the axis direction of drum.

Then, adjacently with above-mentioned first band similarly form second band.Carry out the yarn of aforesaid operations more repeatedly, form section warping drum with a plurality of bands until the necessary total radical of on the warping drum, reeling.In addition, draw yarn simultaneously on the section warping of the yarn of the needed total radical of weaving from the having reeled drum, form a weaving through axle (perhaps also can form a weaving through axle through axle) by a plurality of section warpings.This section warping can prevent equipment enlarging, and is widely adopted as the method that is suitable for producing a small amount of many kinds.

As the structure of carrying out section warping as described above, for example patent documentation 2 disclosed section warping equipment are arranged.The section warping equipment of patent documentation 2 possesses the coiling bobbin cradle as spool rack, and this coiling bobbin cradle adopts the switch type bobbin cradle of the conveyer that has used the turntable form.And each yarn lead division is provided with the winding reel installation portion of the coiling bobbin cradle more than 2 accordingly, and above-mentioned turntable makes this winding reel installation portion can selectively move to the work operations position.

And the section warping equipment of patent documentation 2 possesses from winding reel one side and cuts off yarn and this yarn is attached to automatic cut-out on other the winding reel piecing devices of holding concurrently.Be provided with the so automatic cut-out of the 1 cover piecing devices (with reference to Fig. 4 of patent documentation 2) of holding concurrently at a plurality of yarn lead divisions that flatly are configured to the row shape, this assembly moves between a plurality of yarn lead divisions, cuts off warp thread joint after warp thread maybe will switch according to necessity.In other words, one is cut off the responsible many warp thread of the piecing devices of holding concurrently automatically, moves according to necessity, carries out the cut-out or the joint of warp thread.

The structure of this patent documentation 2 can form the yarn series (color or yarn kind) that a warp band layer (band) back changes the next warp band layer of formation by section warping at every turn.Therefore, can utilize the yarn radical more than 2 to form bigger repetition, the equipment of the compact conformation that does not need the production site that is spacious can be provided than the warp band layer that the radical of the yarn that repeats (promptly constituting the unit that the color pattern of the warp thread of decorative pattern periodically repeats) lacks.Perhaps the warp band layer of Duoing than the radical of the yarn that repeats by the coiling radical can be enhanced productivity.

And, decorative pattern after considering to be made into is disclosed in the above-mentioned patent documentation 1, length at the yarn of measuring versicolor yarn or various kinds on the length direction of yarn in the length of regulation also is rolled into the yarn feeding package continuously, the assigned position that spool rack is supplied with in a plurality of such yarn feeding packages be wound on carry out section warping section warping on axle, form the beaming method of a weaving in the Sectional warping machines of axle then.In the beaming method of patent documentation 1, the linear measure longimetry of yarn is measured save set by yarn length and is carried out.

If adopt the method for this patent documentation 1, only be configured on the assigned position of spool rack by the yarn feeding package after will being rolled into, the section warping that just can access the decorative pattern after reproduction is made into exactly is through axle.And can make the fabric of diversified decorative pattern.

No. 3492335 communique of [patent documentation 2] Japan special permission (0005～0006,0027, coiling bobbin cradle 9, conveyer 10, yarn lead division 14, winding reel installation portion 11, cut off the piecing devices 18 of holding concurrently automatically)

The structure of above-mentioned patent documentation 2 is owing to make the winding reel of choosing move the selection of carrying out yarn to lead division with turntable, and the structure of therefore causing the yarn selecting arrangement increases the rising of equipment cost etc.And automatically cut off the piecing devices of holding concurrently and move and be responsible for carrying out the cut-out of many warp thread and the structure of joint owing to be one, comprise when therefore once switching many warp thread that the stand-by period need spend considerable time, increased stand-by time, reduced production efficiency.

And the structure of patent documentation 2 only discloses the order that intact 1 band of every coiling can change yarn series, and for (form in the way of 1 band) color or the yarn kind that changes warp thread among 1 band, patent documentation 2 does not mention fully.

And if adopt the method for patent documentation 1, have the color or the yarn kind that can change warp thread along the length direction of warp thread in the centre of 1 band, can make the advantage of the fabric of diversified decorative pattern.But such yarn feeding package that has changed the color or the yarn kind of warp thread that the manufacturing quantity that this method needed to add before the section warping process equates with the radical of the warp thread of the whole width of fabric causes and has increased manufacturing process and cost significantly.

And, in the length of measuring yarn with sliver linear measure longimetry save set, change in the method for the color of yarn and the patent documentation 2 that kind is wound into the yarn feeding package one by one, even make the switching point that for example changes yarn of all warp thread as one man be wound into each yarn feeding package, the influence of condition variations such as error that yet can be when measuring length or the temperature when reeling, humidity etc., the position when in most cases carrying out section warping between the switching point in fact can be not consistent and produce deviation.Especially this position deviation has along with the continuation of yarn feeding package is reeled and the character of accumulation, therefore can produce very big position deviation under different many situations according to circumstances.As a result, decorative pattern produces messy or disorderly, is difficult to obtain well the decorative pattern of anticipation.

The present invention wants the problem that solves as mentioned above, the following describes the method and the effect thereof that address this problem.

The 1st scheme of the present invention adopts following structure, and the section warping system is provided.That is, comprise that many warp thread that the spool rack that possesses the yarn feeding package that can lay a plurality of supply warp thread and reeling is simultaneously supplied with by this spool rack form the bulging Sectional warping machines of warping of band.Quantity is set between above-mentioned spool rack and above-mentioned warping drum to be possessed the yarn selecting arrangement and the warp thread that this yarn selecting arrangement is chosen is carried out the yarn switching mechanism of the piecing devices of joint with the radical of the warp thread of a band adapts at least.Above-mentioned spool rack adopts the structure that can lay the package group who is made of the same at least different a plurality of above-mentioned yarn feeding package among color or the yarn kind with above-mentioned yarn switching mechanism correspondingly.Separate the warp thread group of relaxing from above-mentioned package group for the yarn selecting arrangement supply of above-mentioned yarn switching mechanism, this yarn selecting arrangement selects at least 1 to supply with above-mentioned warping drum from supply with next warp thread group simultaneously.

Thus, equally with above-mentioned patent documentation 2 before beginning to form next band behind the band of having reeled, can switch warp thread by enough yarn switching mechanisms.Even the periodicity that therefore forms decorative pattern repeatedly the unit radical and the radical of the yarn of 1 band is inconsistent also can realize this decorative pattern without a doubt, therefore can the implementation structure compactness, section warping system that production efficiency is high, perhaps can increase the performance free degree of decorative pattern.

And, because different with patent documentation 2, the joint that 1 piecing devices only are responsible for a warp thread just can, even so also can carry out at short notice when at the same time many warp thread being carried out switching such as color, can enhance productivity.And,, the control of piecing devices is simplified because piecing devices are corresponding one by one with warp thread.And, because the spool rack employing will be separated the warp thread group of relaxing from the package group and be supplied with the yarn selecting arrangement, from this warp thread group, select the structure of warp thread, therefore structure do not have patent documentation 2 with turntable carry out that winding reel selects big like that, not only can reduce equipment cost, and can shorten warp thread and select to switch the needed time, and then can save the energy that the yarn selecting arrangement is consumed.

In above-mentioned section warping system, preferably possess and carry out in the above-mentioned warp thread with specific length is wound up into way on the above-mentioned warping drum, making the whole or selected run of a plurality of above-mentioned yarn switching mechanism, change the control device of the such control of the selection of the warp thread that is sent to above-mentioned warping drum.

Thus, can in the way of the coiling length of band, change the color or the kind of the warp thread that constitutes this band.Therefore equally with patent documentation 1 can realize more diversified decorative pattern.

And, different with patent documentation 1, the warp thread of the radical of 1 band of can reeling together simultaneously, for each roots of many warp thread can be independently and the while change color or kind concurrently.Therefore can omit numerous and diverse set-up procedure of the package that patent documentation 1 such formation equates with the radical of the warp thread of 1 band, thus can reduce time, operation and cost.And, above-mentionedly reel simultaneously and switch concurrently simultaneously by adopting, can make little than in the patent documentation 1 of the relative error of position that warp thread in 1 band switches the place, can reduce present in the decorative pattern messy or disorderly.

In above-mentioned section warping system, preferably adopt following structure: above-mentioned Sectional warping machines possesses the motor that can drive the rotation of above-mentioned warping drum and control its angle.Above-mentioned control device makes the whole or selected run of above-mentioned yarn switching mechanism after making the angle of above-mentioned warping drum rotation corresponding to predefined switching place, switches the selection of warp thread.

This structure is to determine the structure of the switching position of each warp thread with the anglec of rotation of the warping drum of the warp thread of 1 band of reeling simultaneously.Therefore, can further reduce the relative deviation between the switching position of each warp thread in 1 band, can not produce messyly etc. in the decorative pattern of wanting, can positively show.And the device that does not need special measurement length therefore can simplified structure.

The 2nd scheme of the present invention provides following section warping method.That is, supply with warp thread, they are wound up into the warping drum simultaneously go up the itemize that forms band from a plurality of yarn feeding packages that are placed on the spool rack.Lay on the above-mentioned spool rack that quantity and the radical of the yarn of 1 band adapt by the package group who has at least the same different a plurality of yarn feeding packages to constitute in the color of each package or the yarn kind.Separate the warp thread group of relaxing from this package group and supply with yarn selecting arrangement with the corresponding one by one setting of each package group respectively, each yarn selecting arrangement selects at least 1 warp thread to supply with above-mentioned warping drum from supply with the warp thread group that comes.And, the piecing devices that the yarn that this yarn selecting arrangement is chosen carries out joint are set correspondingly with this yarn selecting arrangement.

Thus, the same with above-mentioned patent documentation 1 can enough yarn selecting arrangements before beginning to form next band behind the band of having reeled and piecing devices switch warp thread, even the periodicity that therefore forms decorative pattern repeatedly the unit radical and the radical of the yarn of 1 band is inconsistent also can realize this decorative pattern without a doubt, therefore not only can make facility compact, can also enhance productivity, can increase the performance free degree of decorative pattern.

And, different with patent documentation 2, the joint that 1 piecing devices only are responsible for a warp thread just can, even so also can carry out at short notice when at the same time many warp thread being switched, can enhance productivity.And,, the control of piecing devices is simplified because piecing devices are corresponding one by one with warp thread.And, because the spool rack employing will be separated the warp thread group of relaxing from the package group and be supplied with the yarn selecting arrangement, from this warp thread group, select the structure of warp thread, therefore structure do not have patent documentation 1 with turntable carry out that winding reel selects big like that, not only can reduce equipment cost, and can shorten warp thread and select to switch the needed time, and then can save the energy that the yarn selecting arrangement is consumed.

In above-mentioned section warping method, preferred above-mentioned spool rack is fixed bobbin cradle.

Thus, can simplify the structure of spool rack, reduce equipment cost.

In above-mentioned section warping method, preferably in the above-mentioned warp thread with specific length is wound up into way on the above-mentioned warping drum, by switching the warp thread of supplying with above-mentioned warping drum with whole warp thread of 1 band or selected corresponding above-mentioned yarn selecting arrangement of a part and piecing devices.

Thus, can in the way of the coiling length of band, change the color or the kind of the warp thread that constitutes this band.Therefore equally with patent documentation 1 can realize more diversified decorative pattern.

And, different with patent documentation 1, the warp thread of the radical of 1 band of can reeling together simultaneously, for each roots of many warp thread can be independently and the while change color or kind concurrently.Therefore can omit numerous and diverse set-up procedure of the package that patent documentation 1 such formation equates with the radical of the warp thread of 1 band, thus can reduce time, operation and cost.And, above-mentionedly reel simultaneously and switch concurrently simultaneously by adopting, can make little than in the patent documentation 1 of the relative error of position that warp thread in 1 band switches the place, can reduce present in the decorative pattern messy or disorderly.

In above-mentioned section warping method, the following structure of preferred employing: above-mentioned warping drum is by controlling the Motor Drive that angle also can drive rotation, after making the angle of above-mentioned warping drum rotation corresponding to predefined switching place, make above-mentioned yarn selecting arrangement and the whole or selected run of above-mentioned piecing devices, switch the selection of warp thread.

As shown in Figure 6, conical package is adopted in yarn feeding package 105.And, the color or the mutually different yarn feeding package 105 of kind (being 6 yarn feeding packages 105 in this example) of several yarns combined, constitute a package group 104.For example, under the different situation of the color of yarn, make the 1st yarn feeding package 105 be red yarn, the 2nd is yellow yarn, and the 3rd is blue yarn ..., and so on.And, the package group's 104 that the radical that above-mentioned spool rack 110 employings can be laid the warp thread of a quantity and an above-mentioned band B of formation conforms to structure.Specifically, in this example, the radical of the warp thread of the band B of Sectional warping machines 102 is 64, and employing can be laid the structure of 64 package groups 104 (for the number of yarn feeding package 5, being 64 * 6=384).In addition, these 64 package groups 104 are provided with correspondingly with the aftermentioned yarn switching mechanism 103 that is provided with 64 equally respectively.

And, the inner space of above-mentioned each yarn ConvertBox 112,112 is separated into horizontal 4 row, vertical 8 row amount to 32 intervals, so interval P, the P of Xing Chenging ... each adopt the structure of accommodating the yarn switching mechanism 103 that constitutes by yarn selecting arrangement 107 and knotter (piecing devices) 108 as shown in Figure 7.

That is, about yarn ConvertBox 112,112 form and add up to 64 interval P, dispose yarn switching mechanism 103 (yarn selecting arrangement 107 and knotter 108) in each.As a result, the yarn radical equal number that has disposed with a band of Sectional warping machines 102 promptly adds up to 64 yarn switching mechanisms 103.In addition, in specific 64 yarn switching mechanisms 103 each, in the following description it is numbered (#1～#64) No. 1～No. 64.

In addition, the symbol 109 among Fig. 7 is for detecting the sensor of broken yarn, this sensor 109 of configuration in each yarn switching mechanism 103.

So, as Fig. 7～shown in Figure 9, each yarn selecting arrangement 107 of yarn switching mechanism 103 be supplied to from the above-mentioned package group 104 of correspondence separate the warp thread group Y, the Y that relax ...Promptly, respectively from the yarn feeding package 5 of 6 versicolor yarns of the formation package group 104 of correspondence respectively separate relax one, amount to 6 warp thread Y, Y ..., these 6 versicolor warp thread group Y, Y ... supply with the yarn selecting arrangement 107 of corresponding yarn switching mechanism 103 through suitable thread-carrier.In addition, for the ease of watching the mid portion that in Fig. 6, has omitted from the yarn feeding package 105 of spool rack 110 to the yarn path of yarn ConvertBox 112.

And, as Fig. 7 or shown in Figure 8, only have the yarn selecting arrangement 107 of supplying with each yarn switching mechanism 103 warp thread group Y, Y ... in 1 (or many) warp thread Y that is suitably chosen by this yarn selecting arrangement 107 be supplied to warping drum 111.

The structure of above-mentioned yarn selecting arrangement 107 is identical with the structure of above-mentioned patent documentation 1 disclosed yarn selecting arrangement, below with reference to Fig. 8 or Fig. 9 simple declaration.This yarn selecting arrangement 107 possess with the warp thread Y, the Y that supply with ... the corresponding setting of quantity (6) 6 thread-carriers 117,117 ... make these 6 thread-carriers 117 can reverse up and down individually, diagram abridged driving cylinder, the suction nozzle (magnetic-attraction element) that can attract the diagram of warp thread Y to dispense can overcome the maintenance roller 118 that line end that this attraction keeps warp thread Y makes its standby.

Each thread-carrier 117 is designed to cylindric, and makes its inside can pass the warp thread Y of supply.And each of 6 thread-carriers 117 can be in conversion between lifting position (chosen position) and down position (select to remove the position or make a concession the position) independently under the driving of above-mentioned driving cylinder.

And above-mentioned knotter 108 is arranged on the downstream near yarn selecting arrangement 107.Because the structure of this knotter 108 is general structure, can adopt for example above-mentioned patent documentation 1 disclosed well-known knotter etc., therefore omit its detailed description.

The yarn switching mechanism 103 (yarn selecting arrangement 107 and knotter 108) that the following describes with this structure carries out the action that warp thread Y switches.As shown in Figure 7, be imported into 6 warp thread Y, Y in the yarn selecting arrangement 107 of each yarn switching mechanism 103 ... be punctured in the yarn selecting arrangement 107 the above-mentioned thread-carrier 117,117 that is provided with ... in, insert 1 in each thread-carrier 117.And, yarn selecting arrangement 107 is selected one or more in 6 yarns, control above-mentioned driving cylinder and make the corresponding thread-carrier 117 of the warp thread Y that chooses with this be positioned at the chosen position of upside, make the thread-carrier 117 of not selected warp thread Y be positioned at the position of dodging of downside simultaneously.

Here, when thread-carrier 117 was switched to chosen position, the end of a thread that is imported into the warp thread Y in this thread-carrier 117 can be submitted to the knotter 108 in downstream.And be positioned at when dodging the position when thread-carrier 117, the end of a thread of warp thread Y is not submitted to knotter 108, is maintained to keep standby in the roller 118.

In the yarn switching mechanism 103 of this structure, in the time will choosing the warp thread Y that supplies with warping drum 111 to switch to the warp thread Y of another kind of color (or another yarn kind) at that time, drive above-mentioned driving cylinder, the thread-carrier 117 of the warp thread Y that is equivalent to supply with is at that time descended, be in and dodge the position, and make the thread-carrier 117 of the warp thread Y that guiding newly chooses rise to chosen position from dodging the position.And, cut off at that time warp thread Y with knotter 108, and will this cut the end of a thread (the end of a thread of warping drum 111 sides) tie a knot with the end of a thread of new warp thread Y.In addition, the end of a thread of not selected warp thread Y (the end of a thread of yarn feeding package 105 sides) is automatically by keeping roller 118 to remain in holding state, in order to select this warp thread Y once more afterwards.So, can switch the color (or yarn kind) of the warp thread Y that supplies with warping drum 111.

Warp thread Y, the Y that is chosen, from above-mentioned 64 yarn switching mechanisms 103, draws respectively by above-mentioned yarn selecting arrangement 107 ... be fed to fabric width as shown in Figure 6 and determine reed 113, because of determining that by fabric width reed 13 is arranged in parallel, then along direction shown in the thick-line arrow of Fig. 6 by the reel length of regulation of warping drum 111, form the band B of Rack.

In addition, above-mentioned Sectional warping machines 102 possesses the motor (motor) 119 that rotation drives above-mentioned warping drum 111, and for example pulse motor or servomotor constitute this motor 119 by the motor that can control angle.This motor 119 links to each other with the controller (warping machines controller) 120 of Sectional warping machines 102, by the rotation of the above-mentioned motor 119 of this warping machines controller 120 controls with stop.And warping machines controller 120 links to each other with the upper system controller (control device) 121 of the whole section warping of control system 101.

The band B that drives warping drum 111 rotation formation specific lengths when motor 119 is very little, and warping drum 111 does not have the effect lower edge axis direction of the driver of expression to move in the drawings, and the 64 warp thread Y that reel under the driving of motor 119 once more form next bar band B.By carrying out several times repeatedly～tens these operations, the section warping of warp thread that can form the whole width with fabric is recoiled these bands with rewinder and is formed weaving through axle through axle, supplies with the weaving operation.In addition, also can merge weaving of formation through axle with being wound on the warp thread of many section warpings on axle.

And, the section warping system 101 of this example as shown in Figure 6, said system controller 121 adopts and is electrically connected with above-mentioned 64 yarn switching mechanisms 103 respectively (only having represented among Fig. 6 #1～#8 yarn switching mechanism 103 input signals), can control the structure of this yarn switching mechanism 103 separately.Though not expression in detail among the figure, system controller 121 in this example adopts well-known micro computer formula structure, not only possess as the CPU of arithmetic element with as the ROM or the RAM of memory cell, and possess to the output unit of warping machines controller 120 or above-mentioned yarn switching mechanism 103 output control signals etc.

Said system controller 121 preestablishes the information of the coiling length of above-mentioned band B, and this length information is stored in the memory cell such as RAM.So system controller 121 calculates the anglec of rotation of the warping drum 111 of the length that is equivalent to this storage, send instruction to warping machines controller 120, drive this anglec of rotation of 111 rotations of warping drum.Accepted the motor 119 of the above-mentioned Sectional warping machines 102 of warping machines controller 120 controls of this instruction, made the anglec of rotation of its rotation appointment.So, can make the anglec of rotation of warping drum 111 rotation regulations, the 64 warp thread Y that reeled simultaneously, the band B of formation specific length.

And, system controller 121 adopts such structure: can be the information (handover information) that the warp thread Y of the warp thread Y of a band B or many band B imported and set the warp thread Y of the cut-out place of warp thread Y and cut-off part respectively according to the decorative pattern after the weaving, this set information be stored in the memory cell such as RAM.

If for the example of an above-mentioned handover information, handover information is such information: when reeling beginning, No. 1～No. 64 warp thread Y all is blue; Leaving coiling starting point 180m place, No. 6 and No. 32 warp thread Y are being switched to yellow; Leaving coiling starting point 230m place, No. 6 and No. 35 warp thread are being switched to redness.In addition, the numbering of warp thread (No. 1～No. 64) for from determine by fabric width to become behind the reed 113 parallel warp thread Y, Y ... an end of width begin the numbering of number, in this example with numbering (No. 1～No. 64, the #1～#64) corresponding of yarn switching mechanism 103.

And, system controller 121 adopts such structure: make 111 rotations of warping drum be equivalent to starting point after the anglec of rotation of the distance of switching place according to above-mentioned handover information, select only to make and the corresponding yarn switching mechanism 103 of warp thread Y (yarn selecting arrangement 107 and the knotter 108) action that needs to switch, switch warp thread Y.

The following describes the concrete example of controlling according to above-mentioned handover information.At first, system controller 121 is given No. 1～No. 64 yarn switching mechanism 103 transmission information, and No. 1～No. 64 warp thread Y all selects blue warp thread Y to supply with.Then, system controller 121 drives above-mentioned motor 119 by warping machines controller 120, begin warp thread Y is wound up on the warping drum 111, drive 111 rotations of warping drum and be in up to the position of yarn switching mechanism 103 and be equivalent to leave starting point 180m place warping drum 111 is stopped the rotation.Then, system controller 121 is given No. 6 and No. 32 yarn switching mechanisms 103 send the instruction of switching yarns, and No. 6 and No. 32 warp thread Y are changed over yellow warp thread Y from blueness.

In addition, the yarn switching mechanisms 103 beyond No. 6 and No. 32 do not carry out change action.That is, leave coiling starting point 180m place, only selecting No. 6 and No. 32 yarn switching mechanism 103 actions in 64 yarn switching mechanisms 103.But this is because the cause that the above-mentioned yarn handover information of this content is set, and is for example setting under the situation of order for the handover information that No. 1 to No. 64 warp thread Y all switched to yellow warp thread, and No. 1 to No. 64 these 64 yarn switching mechanisms 103 all move.

After finishing switching, drive motor 119 once more, drive warping drum 111 specifically and rotate to and make yarn switching mechanism 103 be positioned to leave the anglec of rotation at coiling starting point 230m place that it is stopped.System controller 121 selectively sends the yarn switching commands to No. 6 and No. 35 yarn switching mechanisms 103 then, makes its action, and this yarn switching mechanism 103 is responsible for No. 6 and No. 35 warp thread Y switch to red warp thread Y.

By carrying out such control, the color or the yarn kind that can change the Y of warp thread one by one that constitutes this band B in the way of a band B of reeling are along its length carried out warping simultaneously, can realize diversified decorative pattern.And compare with patent documentation 1 disclosed structure, owing to can not need to form the set-up procedure of the special yarn feeding package that equates with the radical of the warp thread of the whole width of fabric, so can simplify the section warping process significantly.

And owing to determine switching position by the anglec of rotation of control warping drum 111, therefore the deviation between the switching position of warp thread Y is little in a band B, can positively show the decorative pattern of wanting.And, owing to be the structure of the rotation angle measurement length of the motor 119 by warping drum 111, therefore do not need the device of special measurement length, can simplified structure.

But this example can carry out such control: yarn switching mechanism 103 is failure to actuate in forming the way of 1 band B, and all or part of moves change warp thread Y together to make yarn switching mechanism 103 later at the 1 band B that reeled.Also can obtain the effect identical in this case with patent documentation 2.Promptly, after processing 1 band B with Sectional warping machines 102 at every turn, change the yarn series (the color yarn kind of yarn) that forms following 1 band B with yarn switching mechanism 103, thus, constitute the influence of radical that unit that the color pattern of the warp thread of decorative pattern periodically repeats is not subjected to the yarn of 1 band.Therefore can show more freely decorative pattern or enhance productivity.

And, in this example that the knotter 108 that quantity conforms to the yarn radical of 1 band is set, 1 warp thread Y that each knotter 108 as long as be responsible for constitutes band B just can, also share when switching many warp thread Y by a plurality of knotters 108 together, can carry out at short notice.And because 1 knotter 108 is born the switching of 1 warp thread Y one to one, so can simplify the control of system controller 121.And with exchange bobbin cradle mode with turntable the structure of patent documentation 2 of the selection of winding reel rotation carrying out yarn is compared, can simplify the structure of spool rack 110 and yarn selecting arrangement 107, make its compact conformation, also can save the energy (electric power) that consumes when yarn selecting arrangement 107 carries out the yarn selection.

As mentioned above, the section warping system 101 of this example comprises the spool rack 110,110 that possesses the yarn feeding package 105 that can lay a plurality of supply warp thread Y and reels simultaneously and supply with the Sectional warping machines 102 that many warp thread Y that come form the warping drum 111 of band B by this spool rack 110,110.And, between above-mentioned spool rack 110 and above-mentioned warping drum 111, only be provided with the yarn switching mechanism 103 of the knotter 108 that 64 warp thread Y that possess yarn selecting arrangement 107 and this yarn selecting arrangement 107 is chosen tie a knot with the yarn radical (64) of 1 band with conforming to.And, above-mentioned spool rack 110 adopt can with above-mentioned yarn switching mechanism 103 lay correspondingly by the different a plurality of above-mentioned yarn feeding package 105,105 of color or yarn kind ... the package group's 104 who constitutes structure.And yarn selecting arrangement 107 that adopt to give above-mentioned yarn switching mechanism 103 supply with from above-mentioned package group 104 separate the warp thread group Y, the Y that relax ..., simultaneously this yarn selecting arrangement 107 from supply with the warp thread group Y, the Y that come ... in select a structure of supplying with above-mentioned warping through axle 11 at least.

Thus, the same with above-mentioned patent documentation 2, in each yarn series that can enough yarn switching mechanisms 103 changes next bar band B of formation after processing 1 band B with Sectional warping machines 102.Therefore, can utilize the yarn radical more than 2 to form bigger repetition, the equipment of the compact conformation that does not need very free from worry production site can be provided than the band B that the radical of the yarn that repeats (promptly constituting the unit that the color pattern of the warp thread of decorative pattern periodically repeats) lacks.Perhaps the warp band layer of Duoing than the yarn radical that repeats by coiling yarn radical can be enhanced productivity.

This example and above-mentioned patent documentation 2 are in a ratio of spool rack 110 and are fixed bobbin cradle, and from by a plurality of yarn feeding packages 105,105 ... the package group 104 who constitutes draw warp thread group Y, Y ... supply with the structure of the yarn selecting arrangement 107 of yarn switching mechanism 103.Therefore, structure does not have the big like that of (with turntable winding reel is moved and carry out the yarn switching) patent documentation 2, can reduce the electric power of equipment cost or consumption.And, owing to be provided with the knotter 108 that quantity conforms to the yarn radical (64) of 1 band, so each knotter 108 is just passable as long as be responsible for 1 warp thread Y, also can carry out together at short notice even switch many warp thread series.And the control of carrying out the yarn switching also can be oversimplified.

And, above-mentioned section warping system 101 possesses (in the way of the warp thread Y of coiling specific length) in the way of carrying out forming band B on above-mentioned warping drum 111 makes the whole or selected run of 64 yarn switching mechanisms 103, changes the system controller 121 as control device of the such control of the selection of the warp thread Y that is sent to warping drum 111.

Therefore, can make mutual independence of the Y of warp thread one by one that constitutes band B and while change the color or the yarn kind of yarn concurrently along its length, form this band B simultaneously, can realize diversified decorative pattern.And, form the set-up procedure of yarn feeding package owing to can not need patent documentation 1 described such length also to reel continuously, can simplify the process of section warping significantly at the yarn of in the length of regulation, measuring versicolor yarn or various kinds on the length direction of yarn.And, since be many warp thread Y, Y ... be wound up into together on the warping drum 111, in its way, change the color of every warp thread Y or the structure of yarn kind separately, so be not easy between the warp thread Y to produce the position deviation of switching the place, can obtain good decorative pattern.

And above-mentioned Sectional warping machines 102 adopts possesses the structure that can drive above-mentioned warping drum 111 rotations and control the motor 119 of its angle.So, after the said system controller 121 of section warping system 101 can make the angle of above-mentioned warping drum 111 rotations corresponding to predefined switching place, make the whole or selected run of 64 yarn switching mechanisms 103, change the selection of warp thread Y.

Therefore, owing to be to determine the position in the switching place of each warp thread Y, therefore realize the location in more direct switching place by reel the simultaneously anglec of rotation of warping drum 111 of 64 warp thread Y of 1 band B of control.That is, the relative deviation among 1 band B between the switching position of warp thread Y further diminishes, and can show the decorative pattern of wanting exactly during weaving.And, because the motor 119 of warping drum 111 can play the effect of measuring length, therefore do not need to be provided with the device of special measurement length, can simplified structure.

And this example carries out section warping in order to following method.From be placed in a plurality of yarn feeding packages 105,105 on the spool rack 110,110 ... supply warp thread Y, Y ... they are wound up into formation band B on the warping drum 11 simultaneously.Lay on the above-mentioned spool rack 110 quantity conform to the yarn radical (64) of 1 band (64 groups) by the different a plurality of yarn feeding packages 105,105 of the color of each package or yarn kind ... the package group 104 who constitutes.Will from this package group 104 separate the warp thread group Y, the Y that relax ... supply with the yarn selecting arrangement 107 with the corresponding one by one setting of each package group 4 respectively, each yarn selecting arrangement 107 from the warp thread group Y, the Y that supply with ... at least 1 warp thread Y of middle selection supplies with above-mentioned warping drum 111.And, the knotter 108 that the yarn that this yarn selecting arrangement 107 is selected carries out joint is set correspondingly with this yarn selecting arrangement 107.

Thus, with above-mentioned the same, after processing 1 band B with Sectional warping machines 102, can change the yarn series that forms next bar band B by enough yarn switching mechanisms 103 at every turn.And, can enoughly realize same effect, and can shorten the needed time of warp thread that changes than patent documentation 2 simple structures.Especially because the above-mentioned spool rack 110 of this example is fixed bobbin cradle, therefore can simplify the structure of spool rack.

And, in above-mentioned section warping method, the above-mentioned warp thread Y with specific length be wound up in the way on the above-mentioned warping drum 111 can be enough with the warp thread Y, the Y that constitute 1 band ... corresponding above-mentioned yarn selecting arrangement 107 of a part and knotter 108 (being yarn switching mechanism 103) whole or that choose switch the warp thread of supplying with above-mentioned warping drum 111.

At this moment, with above-mentioned the same can be independently and change the Y of warp thread one by one that constitutes band B simultaneously concurrently, can in color that changes warp thread along its length or yarn kind, form this band B, can realize diversified decorative pattern.And, can obtain the little correct decorative pattern of deviation during weaving.

And, warping drum 111 is driven by the motor 119 that can control angle and drive its rotation, after making the angle of above-mentioned warping drum 111 rotations corresponding to predefined switching place, make the whole or selected run of above-mentioned yarn selecting arrangement 107 and knotter 108, change the selection of warp thread Y.

Therefore, by the anglec of rotation control of control motor 119 reel simultaneously 1 band B radical warp thread Y, Y ... the anglec of rotation of warping drum 111, determine the switching position of each warp thread Y.Therefore, can further reduce the relative deviation between the switching position of warp thread Y among 1 band B, can not produce messyly etc. in the decorative pattern of wanting, can positively show.And the device of such special measurement length when not needing patent documentation 1 therefore can simplified structure.
