Description

Warp knitting machine with at least one flower sley bar

Technical field

The present invention relates to have the warp knitting machine of at least one flower sley bar, the flower sley bar has a plurality of by a drive unit and along the reciprocating thread-carrier of sideslip direction, wherein this drive unit acts on thread-carrier by a traction piece.

Background technology

DE4114012C2 discloses a kind of like this warp knitting machine, and its middle yarn guider links to each other with a drive motors by pull rope.Thread-carrier hingedly is suspended on the sley bar support.Therefore, the motion of pull rope converts the oscillating motion of thread-carrier to.Also be provided with the backstop that limits thread-carrier end angle of oscillation, on this thread-carrier end, be provided with guide eye.The backstop if this end reclines, then second lever jack of thread-carrier may be out of shape.

DE2436452B1 has pointed out a kind of warp knitting machine with weft-thread insertion apparatus, and in this warp knitting machine, the thread-carrier of bobbin structure is fixed in the relatively-movable lath.If lath is relatively moved, then the thread-carrier group is also relatively moved.

Under latter event, can control the motion of thread-carrier reliablely, but will be cost with heavier structure; Under first kind of situation, can see the vibration tendency of thread-carrier.

Summary of the invention

Task of the present invention is, under situation simple in structure, realizes the reliable movement control of thread-carrier.

In the warp knitting machine of the described type of beginning, the technical scheme of finishing above-mentioned task is, each thread-carrier has a holding components that stretches along sideslip direction basically, this holding components is substantially perpendicular to a bar and establishes and be rigidly connected with this bar, and wherein this holding components is fixed on the traction piece.

Under the situation of this version, can adopt the less traction piece of its cross section.These traction pieces only bear pulling force and needn't bear pressure.For can control thus thread-carrier and exactly be the motion of thread-carrier guide eye, thread-carrier is a T shape structure, in other words, thread-carrier has a bar, is provided with guide eye in the lower end of this bar.The upper end and the supporter of this bar are rigidly connected.This is rigidly connected and means, when the thread-carrier rapid movement, does not also occur the flexible motion between bar and supporter basically.Therefore, the motion of supporter is directly transferred to the motion of guide eye.Because supporter has certain length to stretch along sideslip direction, so supporter is bearing on the traction piece along certain-length, in other words, by being connected of supporter and traction piece, can receive in certain limit can be by acting on the launched moment of torsion of power on the bar.Therefore, can make thread-carrier highly stablely on traction piece.This produces following result again, and as previously mentioned, traction piece can have small cross section, and its weight is also corresponding to be reduced to some extent.Owing to reduced moving-mass in view of the above, so can improve the operating rate of warp knitting machine.

Traction piece is preferably steel wire or wire rope structure.Steel wire or cable wire can transmit pulling force basically, and pressure is actually and can not transmits.For this reason, control steel wire or cable wire at two ends and apply with power.Make traction piece can be from both sides trailed motion control device itself known for everyone.For this reason, or at one end adopt resetting means, or make steel wire or cable wire return driving by slewing rollers.Adopt a big advantage of steel wire or cable wire to be, this traction piece has little weight and occupation of land is very little, a plurality of traction pieces can be set thus abreast and can control corresponding many thread-carriers in view of the above in a different manner.

The cross section of bar is preferably less than the cross section of supporter horizontal stroke.Thread-carrier is stablized, and this particularly proves favourable under the movement velocity condition with higher.Have bigger cross section and high reliability based on holding components, promptly at first also contending with acts on moment on the thread-carrier then, and cooperating between traction piece and thread-carrier is held.

The length of bar also is favourable less than the twice of the length of supporter.Therefore, the moment that affacts on the supporter remains in the desirable scope.

Supporter preferably has one in order to thread-carrier is fixed on the clamping device on the traction piece.Particularly under the condition that thread-carrier need change in the position on the traction piece, for example in order to regulate a new decorative pattern circulation or a new style, this structure has its advantage.For this reason, only need unclamp clamping device and make traction piece and supporter relatively moves in opposite directions.Under the condition that is fixed again with rear fixture, thread-carrier is to be fixed on the desired position.

In a preferred form of implementation, stipulate that supporter and traction piece are inter-adhesive.In view of the above, though traction piece and supporter seem inseparable turning up the soil and mutually paste, supporter in fact no longer can be done after bonding in the change of the position on the traction piece obtain.If wall is as needing to change the position of supporter on traction piece by changing circulation, then fibrous root adopts a new traction piece and new thread-carrier according to situation.But this structure also has its advantage, i.e. the making of thread-carrier becomes very simple.If can fix to clamp element, for example a screw is not taked structural measure.In addition, save weight is possible, the operating rate of warp knitting machine is improved the load of control assembly is alleviated to some extent.

Here, particularly preferably be, supporter has a groove, is placed with traction piece in this groove, and its further groove is filled with fixing material at least in part.People can for example pack traction piece into and can be used as the groove of open slot structure, spray into adhesive then and for example make its curing under the situation with ultraviolet radiation.Therefore, groove can open wide, and this has saved the material that constitutes supporter.The plastics that are used to paste are lighter." bonding " should be understood that all connected modes, and by these connected modes, the lasting connection between supporter and the traction piece is established.This connection can be established under the situation that has or do not have auxiliary material.

Be provided preferably with a plurality of thread-carriers, the supporter of these thread-carriers is that its king-rod has different length in parallel to each other and towards its overlapping setting in bar ground.By the different length of bar, the guide eye of all thread-carriers is positioned on the line of an imagination.Still can in certain limit, individually control single thread-carrier.

Long bar is best more broadened at its end that links to each other with supporter.Thus one, long thread-carrier can reach and the identical rigidity of the rigidity that thread-carrier had of lacking.Though this broadening can cause taking up an area of when being fixed on long thread-carrier on the traction piece more, this also gives no cause for much criticism, because if need, people can allow broadening position triangular ground be stretched on the thread-carrier group.

Supporter preferably is located in the groove on the sley bar carriage.Have within it and with gap the groove of holding thread-carrier additionally is used for rising stabilization when thread-carrier moves very for a short time.Originally, motion was possible under the situation of the direction of extension that is parallel to groove only.Can be applied moment on the supporter by bar in order to receive, this is another measure.For example welded together or allow the two become being rigidly connected that overall structure forms by bar and supporter based between bar and supporter makes bar by moving with the student movement of supporter same movement.

Supporter has in the centre under the situation of piston shoes and is preferably led in groove, and in order to improve sliding capability, it is favourable that thread-carrier or its supporter directly do not contact with groove face.This contact can form by slide block, these slide blocks between supporter and groove, produce little spacing and can by with the sley bar bracket material as far as possible the material of friction ground cooperating constitute.Usually, plastics are applicable to this very much.In addition, piston shoes are designed to consumable accessory, by changing piston shoes, the life-span that can improve thread-carrier and affiliated sley bar thereof.

Piston shoes preferably are fixed on the traction piece.This structure has two advantages, one, the supporter spacing is bearing in the groove as wide as possible, its two, also prevent traction piece friction cell wall.

Advantageously, piston shoes are as the U-shaped structure and be to snap into and/or adhere on the traction piece.Piston shoes location is close to supporter two as previously mentioned and is brought in and carry out.Blocking is a kind of connection that can throw off fast.And by lasting connection such as adhesion, the stability that can obtain adding.

The sley bar carriage preferably has a lid.This lid covers groove and covers the scope of the bar stretching, extension that thread-carrier is arranged within it.Therefore, this lid causes the raising of lateral stability.This lid can be constituted or applied with this material by sliding material.

Here, particularly preferably be, two sley bar carriages are laid in the centre under the situation of backplate and are reclined mutually with its side with groove.Here, intermediate plate that is thin, that have good sliding capability is just much of that, because thread-carrier is supported therefore not only its motion of not overslaugh, and even raising lateral stability mutually.

Traction piece preferably has screw thread on its at least one end, this screw thread can mesh with a driving member.In order to send into new thread-carrier or unnecessary thread-carrier is taken away when flower to be regulated, traction piece is that steel wire or cable wire must not have on its end and wear only the thickening position or the annular distance of groove.So traction piece is provided with screw thread on its at least one side.This screw thread can realize (or on opposite side with a corresponding clamping device) firm with take up an area of little being connected.After removing transmission device or clamping device, can from groove, extract traction piece out.Nature, available other fixed geometry replaces screw thread, and these solid shapes not or basically do not increase the traction piece cross section equally.What can expect for example is bayonet fittings.

The specific descriptions of embodiment

Fig. 1 represents a colored sley bar 1 with many group 2,3 thread-carriers 4.Every group 2,3 thread-carrier consistent with each other 4, be that every group 2,3 the thread-carriers 4 such as first, second, third, etc. that are respectively are driven by collective, in other words, they can continue to use sideslip direction 6 passive movements that a double-head arrow is represented with respect to sley bar carriage 5, wherein, be provided with a device that is not shown specifically, sley bar carriage 5 can move along sideslip direction 6 equally by this device.

In order to drive thread-carrier 4, be provided with traction piece 7, these traction pieces 7 are for steel wire or wire rope structure and therefore have small cross section.To be perpendicular to the overlapping setting in sideslip direction ground by the traction pieces 7 that following Fig. 2,4 describes in detail.Each traction piece 7 links to each other with a drive motors 9 through a driving belt 8, and wherein driving belt 8 is fixed on its other end in the take up member 10, and this take up member 10 is the air cylinder structure of simple effect.Take up member 10 is accepted pressure by a pressure source P.

The other end of traction piece 7 links to each other with a tension band 11, and tension band 11 is to lead and be fixed on equally in the take up member 13 by a reversing roller 12.The take up member 13 that is similarly the air cylinder structure of simple effect provides compressed air by a pressure source P1.The compression face of the pressure of pressure source P, P1 and take up

member

10,13 is coordinated so mutually, and promptly identical power is applied on the two ends of traction piece 7.Therefore, drive motors need only provide and make the required power of traction piece 7 motions, and tensioning spring or the required power of other tensioning apparatus need not be provided.

Fig. 2 shows the detailed structure of colored sley bar 1.As can be seen from the figure, in a thread-carrier group 2,3, be respectively equipped with eight thread-carriers 4.Thread-carrier 4 is that be arranged side by side and be pulled part 7 and drive along sideslip direction 6.Traction piece 7 is provided with on one transverse to 6 one of sideslip directions.Now thread-carrier 4 is described relatedly with Fig. 3.

Thread-carrier 4 has a bar 14.Be provided with a guide eye 15 in the lower end of bar 14, this guide eye 15 is arranged in a bobbin 16 that is fixed on bar 14.

Fixedly connected with supporter 17 in the top of bar 14, i.e. welding or bar 14 are structure as a whole with supporter 17.Supporter 17 has a slotted hole that passes for traction piece 7.Keep the pinching screw 18 in total value year to be used for supporter 17 is clamped to traction piece 7.If unclamp pinching screw 18, then supporter can move and fixed again by tightening pinching screw 18 on the another location at traction piece 7 upper edge sideslip directions 6.

On the two ends of supporter 17, be provided with piston shoes 19,20.Piston shoes 19,20 have the U-shaped cross section.These two piston shoes 19,20 snap on the traction piece 7 and where necessary useful binders be fixed there, wherein the main task of adhesive is when operation piston shoes 19,20 to be fixed on the end of supporter 17.If desired, thread-carrier 4 moves on traction piece 7, then can make piston shoes 19,20 break away from traction pieces 7 by upwards bending moving piston shoes 19,20 simply, and thread-carrier 4 can be arranged on the new position.

As from seeing Fig. 4, supporter 17 is arranged in the groove 21, exactly, is to be arranged in the groove 21 with leaving a less clearance.Here, piston shoes 19,20 should so be arranged in the groove 21, and promptly supporter 17 does not contact sley bar carriage 5.Piston shoes 19,20 also prevent traction piece 7 and the sley bar carriage 5 sley bar carriage 5 that comes in contact and rub simultaneously.

Owing to a plurality of grooves 21 are arranged in parallel to each other in sley bar carriage 5, so also can place every group 2,3 the same number of thread-carriers 4.Show eight thread-carriers 4.Result of the test shows, in such sley bar, can place every group of thread-carrier that reaches 12 at most.

Sley bar carriage 5, groove 21 covers by a lid 22 to its side of opening wide, and here, covers 22 and stretches out to guide eye 15 so far, promptly covers 22 big parts that also cover bar 14 in the lump.Lid 22 can for example be fixed on the sley bar carriage 5 by a screw 23, should keep in repair, change, takes away or replenish under the situation of single thread-carrier 4, desirable lower cover 22.

Fig. 5 shows a modification form of implementation, in this form of implementation, is provided with two sley bar carriage 5a, 5b.These two

sley bar carriage

5a, 5b have under 22 the situation covered in the centre and recline mutually to side that it opens wide with its groove 21.Wherein, lid 22 is that flexibility is arranged, and in other words, lid can be thin.Thus, each thread-carrier 4 can be on

sley bar carriage

5a, 5b on two along laterally stable mutually, though a plurality of thread-carrier 4 along sideslip direction 6 by relative motion.Lid 22 effects of playing are to make the thread-carrier of sley bar carriage 5a can not run into the thread-carrier of sley bar carriage 5b.

Lid 22 can be constituted or had a plastic coating by sliding material such as plastics.In the example of single sley bar shown in Figure 4, lid 22 itself should have certain mechanical stability, so that obtain lateral stability.

Maybe can take off unnecessary thread-carrier as in circulation Hua Shike being sent into new thread-carrier, traction piece 7 must not have overstriking position or ear handle in its end.Therefore, traction piece 7 has external screw thread 25 at least one end, and traction ear handle 26 can be screwed on this external screw thread 25, and driving belt 8 or tension band 11 can hang in the towing hook 26.

Fig. 7 shows a kind of situation, and wherein all thread-carriers 4 recline mutually along sideslip direction 6.Can find out that therefrom the thread-carrier 4a that is in the groove under being arranged in of its supporter 170 has a bar 14a who is in the weak point of the thread-carrier 4b that is arranged in the groove of going up most than its supporter 17b.The bar 14b of thread-carrier 4b is much longer.

For the thread-carrier 4b with long bar 14b is had and the same mechanical stability of thread-carrier 4a with short bar 14a, be defined among the long bar 14b and widen 27 to some extent towards supporter 17b direction.

Though this those widened sections needs some more spaces along sideslip direction, this also is unblamable, because relative bar 14b, those widened sections 27 also can be a bent angle, and in view of the above, those widened sections 27 generally can be triangular in shape.

Be bearing in the groove 21 by make thread-carrier 4 be fixed on the traction piece 7 and supporter 17 is bearing on the traction piece 7 and by piston shoes 19,20 by supporter 17, thread-carrier 4 very stably is positioned on the sley bar carriage 5, and the wider portion that promptly affacts the moment supported part 17 on the thread-carrier 4 in the scope by guide eye 15 is born.

Determine that several sizes are favourable here.For example, pole length H should be the twice of the length of supporter 17 at the most.The cross section of widening the bar 14 outside the position 27 also is favourable less than the cross section of supporter 17.

As driving belt 8 and the cog belt or the flat band that mesh well as tension band 11 available energies and drive motors 9 or reversing roller 12.Take up

member

10,13 can be designed to have the glass tube structure of graphite piston.Graphite piston moves to be similar at least in glass tube does not have wearing and tearing.Glass piston does not expand and the less air loss is arranged.Can accomplish that as the take up

member

10,13 of the air cylinder structure of simple effect pre-tension performance and length are irrelevant, be used as at for example spring under the situation of tensioning apparatus that pre-tension performance is just relevant with length.Therewith correspondingly, drive motors 9 need only provide and drive the required power of thread-carrier 4, and needn't provide tensioning the required power of resetting means.

Drive the used member of thread-carrier, promptly the quality of traction piece 7, driving belt 8, tension band 11 and piston shoes 19,20 is less, and thus, available schematic structure reaches higher acceleration and operating frequency.

Fig. 8 shows alternative structure of thread-carrier, and wherein, the part consistent with the part among Fig. 3 indicates and add 100 label.

Supporter 117 has a groove 29 that stretches along sideslip direction 6, and this groove is that a side is opened wide.As from can finding out Fig. 8 a, traction piece 7 be put into this groove 29 and be by a kind of fixed substance 28, such as adhesive.Therefore, supporter 117 is fixed on the traction piece so simply, promptly traction piece 7 is put into groove 29, sprays into fixed substance and fixed substance 28 is solidified.Needn't allow fixed substance 28 fill up groove 29 here.Also can be bonding being confined on some longitudinal part between traction piece 7 and the supporter 117.

In this form of implementation, can successfully change the position of thread-carrier on traction piece 7 really.Therefore, in order to allow thread-carrier on traction piece, obtain a reposition, suitably use a new traction piece.Yet making is very simple.This thread-carrier is also lighter usually.

Remaining part such as piston shoes 19,20 also can be used on the thread-carrier shown in Figure 8.
