Description

Warp knitting machine

Technical field

The present invention relates to a kind of warp knitting machine with at least one sley bar, sley bar has the sley bar pin and is suspended on the sley bar bar, and wherein each sley bar bar is connected with sley bar by at least one guide finger and has a revolution fixed part that is used for sley bar.

Background technology

By the known this warp knitting machine of DE 3828469C2.Here each sley bar bar has two guide fingers, and the longitudinal extension of sley bar guided and be parallel to by a guider that is fixed on the sley bar on guide finger by means of ball cover.But guide finger is connected with the guider of sley bar regularly and makes corresponding bearing be arranged in sley bar bar the inside.

Being in operation to make the sley bar pin that is fixed on the sley bar not only on device orientation, promptly be parallel to the longitudinal extension motion of sley bar, and perpendicular moving.First motion is worked thus, and sley bar is offset with respect to the sley bar bar.Second motion is worked thus, makes the deflection of sley bar bar and carries sley bar at this.Also can be responsible for making sley bar to participate in the yaw motion of sley bar bar by the deflection fixed part that a guide finger constitutes.

The sley bar of this warp knitting machine is carried out less relatively journal offset campaign usually in one several millimeters scope, the stroke that therefore leads can keep less relatively, must lay guide finger for the guiding stroke.

When processing knitgoods,, pass through sley bar needle guide yarn then by through axle traction yarn.These obtain the yarn raw material of specified rate according to diameter through axle.The structure of knitwear, especially reticular density, pattern etc. are depended in these yarn consumptions of raw materials.Correspondingly empty through axle later in the running time of determining.This running time is short more, and the operating rate of warp knitting machine is fast more.

When the yarn raw material fully or up to given residual volume when through axle, pulling out, residual yarn is removed from the sley bar pin of sley bar.Then must be with new yarn raw material supplying sley bar.Take off sley bar from the sley bar bar for this reason, and then plug like this, sley bar only is connected with the sley bar bar by guide finger.Make sley bar deflect into one then for the favourable position of knitting worker.

Because the remarkable length of sley bar must make this job step be undertaken by at least two people with relevant therewith inconvenience, is used to avoid damaging sley bar.

Introducing new warp thread, being that new yarn raw material makes sley bar take out from warp knitting machine with opposite order later on again, be connected with the sley bar bar by guide finger then.Need careful especially and the finger tip sensation at this, because the yarn of introducing tends to twist bad or is suspended on machine part the inside and tear fracture now.

The all working that is produced when changing through axle generally can be finished by a people.An exception is to take out and hang sley bar.

In the knitting workshop in modern times, many warp knitting machines are installed simultaneously.But want only to keep the several people simultaneously.A knitting worker takes care of more substantial knitting machine, and they are arranged on a machine usually and arrange the inside.If take place to change, may need other operative employee to work and can not provide at once to carry sley bar for using with maintenance mans or maintenance worker through axle.This means, when changing, produce the repeatedly stand-by period, provide support, be used for taking out or hanging sley bar up to second people through axle.

This point intermittently produces special adverse influence for the production of the warp knitting machine that only has two sley bars, and the yarn consumption ratio of each sley bar is very different in this warp knitting machine.Produce the higher yarn consumption that is far away in the stretch knit product sley bar of in the sley bar of back, handling for warp thread and elastomer in front.Be about 5 to 6 in this ratio, so the sley bar of front must be equipped with new yarn sley bar 5 to 6 times more continually than the sley bar of back.

Summary of the invention

The objective of the invention is, make in the operating interruption of warp knitting machine to keep shorter.

This purpose is achieved in the warp knitting machine of above-mentioned form thus, and described guide finger has a dismountable extension body, moves at the skew stroke that connection status makes sley bar can exceed its standard by it.

Sley bar is moved, make it be turned round fixed part and discharge.Especially advantageously turning round fixed part constitutes by second guide finger.Because guide finger only is used to be offset stroke and mobile fixedly deposit,,, be used to make sley bar to move far enough so guide finger itself has inadequate length for the quality that makes motion parts keeps less.But when making guide finger be furnished with extension body, then guarantee enough shift motions.Because extension body is dismountable, only in the corresponding situation of generation and for when changing the essential mobile deflection sley bar then of yarn raw material, just extension body need be fixed on the guide finger.Extension body can be removed from guide finger more then, be not more than common warp knitting machine at the normal moving-mass that makes in service thus.

Described guide finger preferably is made of pipe and extension body imports to the pipe the inside with a part at least.This design has two advantages.When guide finger is made of pipe, can make the quality of guide finger keep less.The hollow inner of the opposing party's facial canal can be used as the spatial accommodation of an extension body and a part, realizes the highly stable supporting of extension body on guide finger in simple mode thus.

The internal diameter of described pipe is preferably consistent with the external diameter of this part.Although allow little gap, be used for to import the extension body part.But make extension body be bearing in the pipe the inside highly stablely.If extension body partly has corresponding length, then make extension body also sufficiently prevent to tumble.Obtain the self-centering on guide finger in addition.

Described extension body is preferably on the end of this part has a step.This structure has two advantages.Provide a backstop by this way on the one hand, make extension body can be inserted into the pipe the inside up to this backstop.Can make extension body outside with bigger diameter formation on the other hand thus, be easy to make sley bar to shift thus with its guider or sley bar bar at pipe.

Described extension body preferably has a fixed bar, and it can pass the guide finger guiding and have the body that holds that is used for fixing parts on opposite side.This fixed bar forms the part of extension body, and it can inject in the pipe the inside.And fixed part guarantees, when sley bar was offset, extension body can not pull out from guide finger.

Preferred at this, described fixed bar is made of and fixed part is made of nut threaded rod.A nut can be screwed on the screw thread of threaded rod like a cork.Usually can realize relatively quickly screwing on.The bolt connection also need not the bigger torque ground that screws enough stablizes, and is used to make extension body to be fixed on guide finger reliably.

Described extension body is preferably compared with the bearing holder (housing, cover) of guider on the guide finger has undersize.Described guider is had on the extension body than gap bigger slightly on guide finger.But because extension body only is used for making sley bar deflection, so this gap is easy to accept, on the other hand easy operating sley bar thus.

Preferred at this, described guider is guided and extension body radially protrudes in guide finger on guide finger by ball cover.The sley bar bar is pulled out from ball cover and shift extension body and shift.

At least two sley bar bars preferably have a dismountable extension body.Sley bar is supported on its whole length, sley bar is moved by a people, make sley bar be turned round fixed part and discharge.Can make sley bar deflection then, can make yarn be incorporated into sley bar pin the inside thus.Big length for sley bar also can meaningfully have the extension body more than two.

Preferably have a support, it makes sley bar be fixed on deflection state.Knitting thus worker can be with the sley bar braking a position, and this position helps the introducing of yarn.

Description of drawings

Below by means of the preferred embodiment description the present invention that combines with accompanying drawing.In the accompanying drawing:

Fig. 2 is illustrated in the preceding sley bar at diverse location of deflection,

Fig. 3 illustrates an extension body,

Fig. 4 is illustrated in the sley bar of deflection state.

The specific embodiment

Fig. 1 has the part of the warp knitting machine 1 of sley bar 2 with illustrating out of obvious simplification, and this sley bar supports many sley bar pins 3.This sley bar pin 3 is made of vent needle.

Described sley bar has a plurality of sley bar framework 4 as guider with distributing on sley bar length.Also other guider.Each sley bar frame fixation is on two

guide fingers

5,6, and wherein

guide finger

5,6 illustrates in the view of Fig. 1 large.

Described

guide finger

5,6 is separately fixed on the sley bar bar 7, and the antitorque commentaries on classics of sley bar bar ground is connected with outstanding axle 8.Should be suspended on the bearing 9 and for outstanding 8 and on a little angular range, can back and forth rotate by rotary driver 10.Described sley bar bar deflection and make sley bar 2 deflections when rotating by sley bar bar 7.

Described sley bar 2 is in operation and is parallel to its longitudinal extension and is driven by a pattern wheel 11, and it acts on the sley bar 2 by a push rod 12.A back-moving spring 13 is responsible for making push rod 12 always to keep leaning on pattern wheel 11.This pattern wheel 11 drives by unshowned drive unit.

By sley bar framework 4 is separately fixed on two

guide fingers

5,6, each sley bar framework 4 is fixed with preventing deflection with respect to the sley bar bar 7 of subordinate.But this point also is difficult to make sley bar 2 to take a position to, well touches for knitting worker at this position sley bar bar 3.

In order to address this problem, have an extension body shown in Figure 3 14, its operation principle is explained in conjunction with Fig. 2.

Described extension body 14 has a threaded rod 15 and an accommodating section 16.On the end 19 that deviates from accommodating section 16, a nut 17 can be screwed on the threaded rod 15.Accommodating section 16 has an enlarged diameter portion 18 on the end that deviates from threaded rod 15.This extension body 14 has a step 22 on the end of threaded rod 15.This step 22 forms a backstop, and described extension body 14 can inject guide finger 5 the insides up to backstop.Described accommodating section 16 have one than guide finger 5 bigger diameters (Fig. 2 a).Identical in addition parts are furnished with the Reference numeral identical with Fig. 1.

Fig. 2 a illustrates sley bar 2 at " normally " state, guides on two

guide fingers

5,6 at this state sley bar framework 4, and wherein

guide finger

5,6 is fixed on the sley bar bar 7.

In order to change yarn or to carry out other maintenance work, wherein must touch sley bar pin 3 well, guide finger 5 makes extension body 14 be connected with the guide finger 5 on top by threaded rod 15 being interted thoroughly into.Then nut 17 is screwed into from the end 19 of the outstanding threaded rod 15 of guide finger 5, extension body 14 is connected with guide finger 5.In the part that this threaded rod 15 is extension bodies 14, it has an external diameter, and this external diameter is corresponding to the internal diameter of the guide finger 5 that is made of pipe.

Fig. 2 b illustrates a state of extension body 14, and it is connected with guide finger 5 at this state.Can see that accommodating section 16 has an external diameter more bigger than guide finger 5.But the external diameter of this accommodating section 16 has one slightly less than the external diameter of ball cover 20 external diameters, and this ring set of sley bar framework 4 usefulness is guided on guide finger 5,6.Make sley bar framework 4 have two unshowned bearing holder (housing, cover)s, they constitute by the hole under the simplest situation for this reason.

In case extension body 14 is connected with guide finger 5, can make sley bar 2 with the offset path skew that its sley bar framework 4 exceeds standard, sley bar is discharged by ball cover 20.The size of this mobile route makes sley bar framework 4 be discharged by the guide finger 6 of bottom fully.Make sley bar 2 deflection as shown in Figure 4 then, the sley bar pin 3 of sley bar 2 can freely be touched for knitting worker.

Can be at this position sley bar 2 by support member 21 supportings, this is supported under the simplest situation and is made of bar, and it is being arranged between two fixed

parts

22,23 on sley bar 2 or the sley bar bar 7.Described support member 21 can be removed when no longer needing to make sley bar 2 be fixed on inflection point (Fig. 4).

If yarn has been incorporated into sley bar pin 3 the insides, make then sley bar 2 with its sley bar framework 4 with opposite sequential movements.At first make sley bar 2 remove support 21, aim at its bearing holder (housing, cover) and two

guide fingers

5,6 up to sley bar framework 4 with backswing.And then the sley bar framework is retracted, sley bar framework 4 is bearing on the ball cover 20.By spinning down and make extension body 14 from guide finger 5, to pull out from threaded rod 15 on nut 17, remove extension body 14.Sley bar 2 is available again then.And also essential sometimes mount portion prevents that sley bar framework 4 from pulling out from guide finger 5,6.But this fixed part in most of the cases constitutes by push rod 12 and pattern wheel 11.
