Description

Fancy beam warping device

Technical field

The present invention relates to a kind of beam warping device (Musterbaumschaervorrichtung), this device has: frame; Fancy is through axle; Fancy is through the axle holding device, and fancy rotatably is maintained in this holding device through axle; Roller arrangement, when reeling, fancy is close in this roller arrangement through axle; And reciprocal reed, this reciprocal reed can be supported to the axis that is parallel to the fancy beam warp.

Background technology

Modell HDSM 130/2R der KARL MAYER Textilmaschinenfabrik GmbH for example, Bruehlstrasse 25, and 63179Obertshausen, Deutschland disclose a kind of such fancy beam warping device.

Through such fancy beam warping device, can produce and have many fancy along the silk thread that vertically is arranged side by side volume through axle.Yarn package is wound onto on the coiling body with about identical lateral extent, and this coiling body forms vertical pipe.From the purpose that describes below, unwound pipe all is called as " fancy is through axle " with the pipe with yarn package.

Fancy has trunnion through axle on two ends, through trunnion, fancy not only can laterally be fixed on the fancy beam warping device through axle rotatably, and can in the process of back, can laterally be fixed in the warp knitting machine rotatably.When producing fancy through axle, and when the coiling yarn package, it is driven, and therefore the winding diameter of single winding element has identical diameter as much as possible when winding pressure is identical.

Join the fancy of reeling in the warp knitting machine and to warp knitting machine through axle and to supply with Fancy Yarns, this Fancy Yarns is added in the ground of knitwear.

Warp knitting machine generally has about 3.3 meters working width, in this warp knitting machine, when disposing such fancy through axle, in most of the cases, produces lace.Lace is distributed on the working width of warp knitting machine abreast, and has the identical fancy that is identical floral designs (Motiven).Lace at first be added into one with the corresponding base fabric width of cloth of working width in, and be separated into independently lace in the course of work at first below.This working width of warp knitting machine is corresponding through the over-end winding zone of axle with fancy usually.Strive for making lace to have identical optical appearance.Therefore, make and form fancy and have certain meaning through the stress of the silk thread of axle is identical as far as possible.

Be used for producing this fancy and have a roller arrangement through the known fancy beam warping device of axle, this roller arrangement has two driven rollers.Fancy is installed in the bed of reeling producing yarn package through axle, and this coilings bed forms through the coiling between two rollers.When roller rotates, realize that through circumferential force fancy drives through the rotation of axle.In the ordinary course of things, fancy is just enough through the deadweight of axle.If its deadweight is not enough, then can apply auxiliary thrust.

Because the yarn package of fancy on axle have certain stability, therefore so reciprocal reed is set, promptly this reciprocal reed is parallel to fancy and moves back and forth through axle when coiling.Therefore, the mode with the intersection volume produces each yarn package.

Unwinding fancy yarn from the unwinding yarn bobbin cradle, and come to confirm in advance yarn stress through being arranged in Yarn Brake in the bobbin cradle.

Fancy is fixed on the axial location through the trunnion that is arranged on the end through axle.But because diameter increases when reeling, so fancy is shifted out from the bed of reeling when axle is being reeled.Therefore produced such shortcoming, promptly changed to the silk thread distance on the silk thread induction element of reciprocal reed from the coiling surface of fancy through axle.On the other hand, it has such shortcoming, and the ratio between the pace of change of winding diameter that promptly increases and reciprocal reed poorly changes.Back and forth reed needs such drive unit in this case, and promptly this drive unit is so controlled, so that the distance between coiling surface and the silk thread induction element always keeps near identical.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure and can controlled fancy beam warping device.

This purpose realizes that through following method promptly fancy is supported on the frame around swinging axle through the axle holding device swingably in the described the sort of fancy beam warping device when beginning, this swinging axle is arranged to be parallel to the axis of fancy through axle.

Support fancy by this way through axle, promptly when the diameter of yarn package increased, back and forth the yarn induction element of reed had kept the distance to coiling surface, and reed needn't be along radially leaving fancy through axle.Fancy is followed the pendulum radius of rocking bar through axle when winding diameter increases, fancy beam warping device has formed this pendulum radius.Through this layout, not only make the control of motion of reciprocal reed simpler.Also can realize in fact higher winding speed, wherein can realize that through keeping identical coiling pulling force best yarn lays by plain mode.

Preferably, roller arrangement has driven roller.It makes the simple in structure of fancy beam warping device.During through axle, only need a unique roller in the swinging mounting fancy.In a unique roller, the twice of fancy when axle is actually at two rollers of use owing to gravity is applied to the lip-deep extruding force of roller is big, and when using two rollers, fancy is close on two rollers through axle simultaneously.Correspondingly, between axle, produced bigger frictional force, can utilize this bigger frictional force to improve winding speed at driven roller and fancy.

Preferably, back and forth reed has at least one thread-carrier, and this thread-carrier is arranged on such plane, and promptly this plane and fancy are extended through axle and roller tangently.In this case, can realize the yarn movement path, in this yarn movement path, not with roller or fancy under the prior contacted situation of axle, reel for yarn around fancy on axle.Therefore make reciprocal reed oversimplify.But, at first, can changing along with higher relatively speed, this itself produces positive impact to winding speed, and this winding speed has correspondingly been increased.

It also is favourable on this plane that swinging axle is arranged in.Can realize that in this case in fact fancy does not change when reeling through the place that axle is contacted with driven roller.Though can produce less moving under these circumstances.But this is unessential.

Axis of oscillation and fancy also are favourable on the not homonymy of axis arranged at vertical plane of axle, and wherein this plane extends through roll axis.In this case, the diameter that can form yarn package particularly well increases needed motion, and the measure that need not assist.

Description of drawings

With reference to accompanying drawing the present invention is described by means of preferred embodiment below, wherein:

Fig. 1 is the sketch map of fancy beam warping device;

Fig. 2 is the side view that does not have the fancy beam warping device of sidepiece part;

Fig. 3 is the view in the cross section of changeable device;

Fig. 4 is the sketch map of exemplary bearings;

Fig. 5 according to Fig. 4, be used for the view of the fancy beam warping device of prior art.

The specific embodiment

Fancy beam warping device 1 has frame 2, in this frame 2, in this example, can produce two fancy simultaneously through axle 3.Therefore, the many yarns of unwinding from bobbin cradle 4, and provide predetermined yarn stress through the Yarn Brake that is not shown specifically.Through making fancy realize unwinding through the method that axle 3 is rotated.

Fig. 2 shows the cross section of fancy beam warping device, in this cross section, has identical mark with Fig. 1 components identical.In frame 2, arrange a driven roller 5, this driven roller 5 has oneself a rotating driver, and correspondingly can be in the rotation status.Arrange fancy through axle 3 along the gravity direction of driven roller 5 tops, this fancy is supported on the rocking bar 6 through two axial ends of axle 3.Rocking bar 6 can be around swinging axle 7 swings.

Unwinding yarn 8 from the bobbin cradle 4 that among Fig. 2, is not shown specifically, and this yarn 8 is through the thread-carrier 9 of reed 10, and this reed combines Fig. 3 to describe in detail.

Reed 10 is parallel to fancy through driver 11 and moves back and forth through the axis of axle 3.Therefore, driver 11 has rotation motor 12, and this rotation motor 12 is clearly shown that like 13 of double-head arrows that works and carries out work with the direction of rotation of alternation.Motor 12 links to each other with axle 14, and axle nut 15 is arranged on this axle, can prevent that this axle nut 15 is rotated.Axle nut 15 links to each other with reed 10.When motor 12 carried out work with alternating rotating direction 13, reed 10 moved back and forth along the direction of double-head arrow 16, and had produced yarn package 17, and this yarn package 17 forms with the mode of intersection volume.This yarn package 17 remains on fancy on axle 3 relatively stablely, so yarn here can not slide.

In order to produce this yarn package 17 reliably, if thread-carrier 9 with respect to the circumferential surface of yarn package 17 along radially having certain and constant as far as possible distance, this is favourable.In order to ensure this distance, fancy is supported on the rocking bar 6 as when beginning is said through axle 3.

Consequently, fancy is moved in circuit orbit 19 through the axis 18 of axle 3, and the mid point of this circuit orbit has formed swinging axle 7.In fact contact point 21 between driven roller 5 and yarn package 17 can not change.In each case, the change amount of contact point less than schematically illustrate among Fig. 5 according to the change amount in the fancy yarn warp beam device of prior art.

Here, fancy through axle 3 be close to two driven

roller

5a, 5b is last.If fancy increases through the diameter of axle 3, corresponding contact point 21 moves towards the direction of reed 10 so, tracks 22 radial displacements when therefore forcing reed 10 along coiling.

In the embodiment of the fancy beam warping device that Fig. 4 schematically shows, do not need this motion.

The thread-carrier 9 of reed 10 is arranged in the plane 23, and not only extend through the yarn package 17 that axle 3 is formed at wherein more precisely with fancy tangently on this plane 23, but also extends with driven roller 5 tangently.In preferred especially a layout, swinging axle 7 also is arranged in this plane 23.But this last characteristic is not absolute demand.

Plane 24 vertically extends through the axis 25 of driven roller 5.Fancy is positioned on the side on plane 24 through the axis 18 of axle 3.Swinging axle 7 is arranged on the opposite side on plane 24.In this manner, fancy is maintained on the driven roller 5 through a pulling force that is applied by rocking bar 6 through axle 3 on the one hand.On the other hand, for the tracks along circuit orbit 19 has produced enough big free space, when forming yarn package 17, fancy is moved in this circuit orbit 19 through axle 3 in this way.
