Description

The fancy warping machines

Technical field

The present invention relates to a kind of fancy warping machines with warper drum, thread guide device and a plurality of crossing rods, the thread guide device has at least one thread guide, wherein, thread guide and warper drum can move relative to each other along direction of rotation around the axis of warper drum, and the device of guiding silk thread is provided, concerning each crossing rod silk thread guided to above the described crossing rod by thread guide or below.

Background technology

Be known as again the fancy warping machines of " short warping machines " for the production of the warp thread with finite length, during producing warp thread, wish to keep style type as much as possible.

For this reason, so-called tow is wound up on the circumference of described warper drum.Such tow can comprise the silk thread of one or more arrangements adjacent one another are.Reeled need the warp thread of length after, described tow is offset as follows, it can carry out described operation again near the tow of already having reeled.In case of necessity, the order of the silk thread in the tow and/or quantity optionally change.

After the warp thread of finishing by this way required width, described tow is blocked with terminal in the beginning of its length.In order to realize this purpose, provide in a manner known way at the beginning of warp thread and the crossing rod of terminal formation lease making.Other crossing rods can be provided, for example, be used for starching and distribute.

For the end at described warp thread forms described lease making, the last coiling of described tow for example, must guide to above the described crossing rod.The every other coiling of described tow must be positioned at below the described crossing rod.In this article, concept " is higher than " described crossing rod and represents that described tow is positioned at the radial outside of described crossing rod (relatively warper drum).In this article, concept " is lower than " described crossing rod and represents that described tow is between described warper drum and crossing rod.

For the respective guide silk thread, there are some possibilities.A kind of possibility is included as described crossing rod assembling catch pawl or ratchet, and if necessary, they can stretch out and catch silk thread, and it is guided to above the described crossing rod.Another possibility is, the axis that temporarily is parallel to as follows described warper drum at described thread guide during by described crossing rod moves described thread guide, with the silk thread unwinding of guiding on described crossing rod or guide described wire spool to the tip by described crossing rod, consequently, during further processing, it is positioned at below the described crossing rod.

But, along with speed of beaming improves, guarantee that the described ideal position that silk thread enters relative crossing rod becomes more and more difficult.If described silk thread is arranged in below the described crossing rod mistakenly, although it should be arranged in above the crossing rod or on the contrary, warp thread blocks just relative difficult with unwinding according to priority subsequently.Therefore, certain restriction has been occured in speed of beaming.

Summary of the invention

The present invention just is being based on the purpose that realizes high speed of beaming in the fancy warping machines.

Partly mention at preface on the fancy warping machines of type, this purpose is by following true the realization, and at least one crossing rod can be installed on the diverse location of axis of relatively described warper drum.

Therefore, can as follows described crossing rod be positioned on its position, and the radial thickness that described silk thread batches matches each other.This is specially adapted to crossing rod, and wherein, described silk thread must be arranged in its most of coiling below the described crossing rod.Therefore, the position of the described crossing rod warp length that can meet the needs of.Formed to consist of by described warp length and wished the necessary coiling quantity of length.Described coiling quantity is obtained divided by described warper drum girth by described warp length.Described coiling quantity multiply by wire thickness can obtain the size that described silk thread batches radial thickness.If too near described warper drum, consequently, this thickness can be lower than rated value to described crossing rod, does not have enough spaces can supply the warp thread utilization.The warp thread silk thread of reeling is outwardly-bent with described crossing rod subsequently, consequently the tip of described crossing rod no longer be positioned at it actual should the present position.Therefore, guarantee that described silk thread is positioned at above the described crossing rod in the mode of needs or below become more difficult.If described crossing rod from described warper drum too away from, identical problem can appear.In this case, although there are enough spaces to be used for the thickness that described silk thread batches, described silk thread batch and crossing rod between also have extra sky.The silk thread that is wound on above the described crossing rod radially curves inwardly described crossing rod subsequently, consequently, identical problem occurred.On the contrary, if the described crossing rod axis location of relatively described warper drum radially just this problem can not occur.Described crossing rod can be with location as follows, and it seldom even can be crooked by the silk thread of described coiling, and consequently, its tip always is in ideal position.Therefore, can obtain high speed of beaming by enough pinpoint crossing rods.

Described crossing rod preferably can pass through the anchor drive displacement.The location of described crossing rod can be realized in the mode of Long-distance Control, realizes during operation in case of necessity, not yet occupies the tram if described crossing rod shows.Described anchor drive can consist of with the Linear actuator form with plain mode.It only need to guarantee that axis that described crossing rod can relatively described warper drum extends radially out and shrinks.At this moment, during movement even do not need accurately to keep its radial direction.Therefore, described anchor drive relatively tangential direction vertically acts on described warper drum, and, if necessary, can also relatively it form certain angle.

Described crossing rod preferably is connected separably with described anchor drive.Its advantage is, if necessary, described crossing rod can be removed from described anchor drive easily, for example, and during the finished product unwinding the warp.

But, particularly preferably be, described crossing rod is connected with at least two anchor drives distributions on its length, and they can be thrown off with described crossing rod independently of one another.By at least two anchor drives, when the warping operation began, described crossing rod can be fixed on two or more aspects, and consequently, for example, it can accurately be parallel to the Axis Extension of described warper drum, has simplified thus the formation of warp thread.But, along with width increases, described warp thread departs from the end at described silk thread place at described warper drum top offset.In this case, described anchor drive can prevent that described warp thread is moved further.Thus, described anchor drive can be at first with the most close described silk thread crossing rod endways throw off.Described anchor drive is thrown off and is shunk that to enter described warper drum be that described warp thread is transported from described end during warping, arrives to finish soon before this driver.For this reason, the disengagement of described anchor drive is not crucial.At this constantly, described crossing rod was fixed with enough degree by described warp thread already.

Preferably provide and can measure the sensor device that silk thread batches height, described sensor device is connected with described anchor drive.Therefore, described sensor device can position described crossing rod as follows by described anchor drive, and height or the relative accurately coupling of thickness are batched with described silk thread in this position.Generally, when beginning, the warping operation must carry out warping to a plurality of tow for this.At this moment, unimportant if described crossing rod is in incorrect position.But, in case the formation that silk thread batches is already stable, described crossing rod namely is movable to its tram.Be installed on the warper drum circumference if will have the transport tape of taper support face, the mensuration of the thickness that described silk thread batches generally can be carried out after first tow.

This moment, preferably described anchor drive was positioned at described crossing rod on the position, and wherein, described silk thread batches and highly keeps freely being lower than described crossing rod.As what above already illustrated, this is the tram of described crossing rod.Described crossing rod allows radially along the axis direction of described warper drum enough spaces to be arranged, and consequently, can hold that silk thread batches or all coilings of warp thread.But, the described silk thread of described crossing rod distance batches and is not too far away, and when silk thread radially outward was wound on above it, it radially curved inwardly.

Described crossing rod preferably is fixed on the described warper drum.In this case, can use and have the to a great extent warper drum in columniform cross section.Use such warper drum, can obtain high speed of beaming.

Described warper drum is preferably rotation during warping, and thread guide is fixing along described direction of rotation position.This is the measure that obtains higher speed of beaming equally.Described thread guide motion can be limited to the pure motion that is parallel to described warper drum axis.This has also simplified control.

The feed surface preferred arrangement is on the circumference of warper drum, and described feed surface can be parallel to by the feed drive device axis shift of described warper drum, and described feed drive device and anchor drive are synchronized with each other.When described feed drive device with feed surface from the Filament winding of described warper drum after the terminal mobile predetermined distance, described the first anchor drive can be thrown off from described crossing rod, and described anchor drive can shrink.In fact, correct situation is automatically to guarantee, at this moment, described anchor drive is described warp thread cleaning passage.

In alternative or supplementing structure, can provide warp width to determine device, it can be measured the silk thread that is parallel to described warper drum and batch length, and described warp width determines that device has the control output that is connected with described anchor drive.For example, described warp width determines that device can be made of the sensor of measuring warp width or only measure away from the position of warp thread one side of described end.Because the width of coiling tow is known, described warp width determines that device can also be made of the counter of measuring coiling tow quantity simply.This has guaranteed that also described anchor drive shrank in correct time, and that is to say not can be too late, can be too not early yet, in order to warp thread is being cleaned out the required space of described warp thread when the end of coiling silk thread is transported.

Description of drawings

In following specification, the present invention will be described by a preferred typical embodiments in connection with accompanying drawing, wherein:

Fig. 1 represents the perspective schematic view of fancy warping machines, and

Fig. 2 represents the schematic diagram of anchor drive.

The specific embodiment

Fig. 1 schematically shows fancy warping machines 1, and it has a warper drum 2 that is connected with the rotating driver 3 that only schematically shows.During winding the line, rotating driver 3 can rotate warper drum 2 along direction shown in the arrow 4.

At the bobbin cradle that is not shown specifically a plurality of bobbins have been installed.In this typical embodiments, nearly 128 bobbins can be installed on described bobbin cradle.Pull out silk thread from each bobbin, and guide by the thread guide eyelet 5 of thread guide 6.All thread guides 6 have consisted of thread guide device 7 jointly.

During warping, that is to say that thread guide 6 remains static along the direction of rotation 4 of described warper drum 2 during producing pattern warp.But, thread guide 6 can be in axial direction, and the direction that is parallel in other words described warper drum 2 axis moves, and exactly, is in axial direction to guide thread guide eyelet 5 on warper drum 2.Subsequently unwinding of silk thread by thread guide eyelet 5 guiding is on the transport tape 8 that consists of feed surface, and if from the end of described warper drum 2 to warper drum 2, they are arranged in polygon.The outside reversion section in the corresponding footpath of transport tape 8 moves away from the end that thread guide device 7 is installed by feed drive device (not shown in detail).If silk thread is taken out from the fancy operation, just not unwinding is on the circumference of warper drum 2 for they, but thread guide eyelet 5 moves to the terminal front of described warper drum 2.Silk thread by described thread guide 5 guiding is wound up on the rachis (not shown in detail) subsequently.

Distribute in order to form so-called lease making or starching, the crossing rod 9 that is installed between the transport tape 8 is provided.Each crossing rod 9 has a tip 10 of pointing to substantially its radially outer at its end towards thread guide device 7.At this moment, most advanced and sophisticated 10 be fixedly mounted on the crossing rod 9.

Each crossing rod 9 is fixed on two

positions

11,12 on the warper drum 2 at least.Therefore, when warper drum 2 rotation, crossing rod 9 rotates with warping cylinder 2.

Fig. 2 represents that crossing rod 9 is fixed on the position 12.At this moment, warper drum 2 has opening 13, by it anchor drive 14 is radially outward guided.Anchor drive 14 has can be along the push rod 16 of double-head arrow 15 direction displacements.Have two

pawls

17 ,18 pliers is installed in the radial outer end of push rod 16, and described

pawl

17,18 is with the fixing crossing rod 9 of clamping mode.But,

pawl

17,18 can be along direction rotation shown in the arrow 19,20.For the sake of clarity, not shown necessary driver here.When pawl 17,18 had rotated when leaving crossing rod 19 already, anchor drive 14 is thrown off with crossing rod 9.Can radially move inward with rear push-rod 16, consequently,

pawl

17,18 no longer extends beyond described warper drum 2.

But, if push rod 16 already radially to intrinsic displacement to a certain degree, so that the

pawl

17,18 of pliers no longer radially extends beyond the words of outer reversion section of transport tape 8 is just basically enough.The outer reversion section of transport tape 8 has formed on described warper drum, that is to say that the silk thread of formation is rolled up the inner boundary 21 that the upper silk thread that forms batches.

End at warper drum 2 is provided with sensor device 22.Described sensor device 22 at first detects the position of described crossing rod 9.Secondly, it can also determine height or the thickness that transport tape 8 the above silk thread batch.

For the control inputs 23 of anchor drive 14 provides this thickness information.By this thickness information, anchor drive 14 can be located crossing rod 9 as follows, and the space that namely silk thread batches and thickness is required can accurately provide between the inner radial of crossing rod 9 and border 21.Consequently, crossing rod 9 batches by described silk thread and is not radially outward to press, but crooked.But, on the other hand, crossing rod 9 neither by radially outward being guided to the silk thread on the crossing rod 9, in other words be arranged in the inwardly inwardly bending of footpath of silk thread above the described crossing rod.

The advantage of this structure is that the tip 10 of crossing rod 9 can not batched bending and change its position by described silk thread because of crossing rod 9.Therefore, when producing lease making, can be as follows around the described thread guide eyelet of tip 10 guiding of crossing rod 9, the silk thread of respective guide can be directed to (that is to say the radial outside of crossing rod 9) or crossing rod 9 following (in other words crossing rod 9 is radially following) above the crossing rod 9.Because therefore most advanced and sophisticated 10 position can not changed by the silk thread of described coiling, can in to the not too large situation of the expense of thread guide 6 controls, obtain high speed of beaming.

When described silk thread batches, when the warp thread that is to say formation reaches certain width (=be parallel to the degree of described warper drum 2 axis ), it approaches and is installed in position 12, that is to say the locational anchor drive 14 near the end that thread guide device 7 is installed.At this moment, the push rod 16 of anchor drive 14 can hinder and further carry described warp thread to leave described end.But, when described warp thread reached position 12, it had fixed crossing rod 9 with high reliability.No longer need in principle other fixators.Then, remove pawl 17 by rotation ,18 throw off anchor drive 14 and crossing rod 9, and push rod 16 radially moves inward to a certain degree, in order to remove the space between border 21 and the crossing rod 9.When warp thread in-position 11, repeat identical operation, and in other positions crossing rod 9 is fixed on the warper drum 2 in case of necessity.

Contraction can be too early or do not crossed for the push rod 16 that makes corresponding anchor drive 14, a series of information can be used.

Because described warp thread, that is to say that described silk thread batches by described transport tape or is commonly referred to as feed surface to carry the distance that described feed drive device can reach described information conveyance to described feed surface.When described feed drive device therefore described feed surface is moved away warper drum 2 install the end of thread guide devices 7 predetermined apart from the time, described silk thread batches (=warp thread) to a certain degree near relevant position 12, so that push rod 16 must shrink.

As an alternative or supplement, the sensor (not shown in detail) that can use the described warp thread of mensuration or silk thread to batch thickness.In many instances, away from described warper drum 2 position at warp thread edge of end of thread guide devices 7 to be installed also just enough if described sensor can be measured.

Another possibility comprises when described tow is known, determines the width of described warp thread by the width of cumulative coiling tow.Tow is comprised of one or more silk threads of reeling simultaneously.The above simply mentioned, and tow can have 1-128 silk thread in this example.Be not that all tow must be wide.But, because the fancy of wishing is known, the composition of described tow and width are known equally.

In principle, identical solution also can be used for crossing rod 9 tip 10 not and the situations that solitarily are connected of crossing rod 9.In this case, most advanced and sophisticated 10 are designed to ratchet, and it can rotate on the passage of silk thread, in order to silk thread is guided to above the described crossing rod, perhaps it to remain on the silk thread passage outside so that with the silk thread unwinding below crossing rod 9.

During the warping, if warping cylinder 2 is static, and thread guide 6 also can use shown device around the axis rotation of warper drum 2.
