Description

The braiding tool support

Technical field

The present invention relates to a kind of braiding tool support, with a plurality of braiding instruments, each braiding instrument has workspace, fixed area and two narrow sides of pointing in opposite direction, and wherein, the braiding instrument is arranged to spacing side by side parallel to each other and that the space is predetermined.

Background technology

Usually in braiding machine generally, with a plurality of braiding instruments concentrate on one the braiding tool support in.The braiding tool support often has the width of one or two inch (Zoll), and admits the braiding instrument of respective numbers according to precision.

The concept of " braiding instrument " referred to herein as the especially abbreviation of those elements of participation knitting cycle when producing braided fabric of warp knitting machine of braiding machine.The braiding instrument not only relates to original braiding instrument such as knitting needle, slide block, sinker etc., also relates to thread-guide element, if any eye pin, pectination press strip (Kammplatine) etc.

When a plurality of braiding instruments were assembled one group in carriage, these braiding instruments can obtain faster install and adjust at braiding machine.

Initial people cast the braiding instrument in order to produce carriage with lead.The defective of doing like this is to be accompanied by very large quality, and this can have a negative impact to the operating rate of braiding machine.The temperature that occurs in when casting also can allow the braiding tool variations, and this is so that necessitate to the post processing of wasting time and energy of braiding tool support.

In DE 10 2,009 010 316 A1, advise, cast the braiding instrument with plastics.

DE 196 18 368 B4 have described a kind of braiding tool support, and with support, support has groove.Groove is filled with the filler that can harden, and when filler is also unhardened the braiding instrument is placed filler.

In the machine of fast operation, not only weave tool bar, and the braiding tool support, all must have very high rigidity and enough intensity.This can cause the wall thickness of braiding tool support larger when using for the former thereby preferred plastics of weight or light metal.This causes again the quality of not expecting occurring giving birth to and improves.In addition, people for example are subject to sley point (Legenadeln) when selecting guide, because yarn should not bump against with the braiding tool support.

Summary of the invention

Technical problem to be solved by this invention is, a kind of braiding tool support is provided, and it only needs very little structure space when rigidity is very large.

Start in the braiding tool support of described type at this paper, this technical problem solves thus, that is, the braiding instrument is arranged between two cover plates, and wherein, narrow side and cover plate are bonding.

Use this design, only adhesives just can couple together braiding instrument and braiding tool support on a small quantity.This amount only must be set up the connection between the narrow side of braiding instrument and cover plate.When mounted, the braiding instrument is arranged side by side with desired calibration and for example locates by corresponding standard.Then adhesives can be coated on the narrow side of braiding instrument or be coated on the side of cover plate, then that cover plate and braiding instrument is bonding.Then the narrow side at other repeats identical process.Certainly, these two bonding process also can carry out simultaneously.Then form a kind of sandwich composite construction that is consisted of by two cover plates and braiding instrument.Surprisingly, bonding on narrow side of braiding instrument is enough to provide a kind of braiding tool support, this braiding tool support to have very little quality and under any circumstance all has enough rigidity after the braiding tool support is fixed on the corresponding braiding tool bar.

Each braiding instrument preferably has rod member and cover plate in FX and this rod member is bonding.Therefore createed the contact area that limits at the braiding instrument for cover plate.This has simplified manufacturing.

Rod member preferably has projection at least one narrow side, and projection exceeds giving prominence to of cover plate distolaterally, and wherein, projection has and described distolateral bonding abutment face.Projection can be configured to only hide the part of distolateral thickness, thereby produces corresponding less bonding plane.But projection also can be constructed greatly to making abutment face have the same with distolateral extension at least large extension.In this case, carry out on the bonding surface that is connected to maximum possible.Then the braiding instrument can be said to a certain extent towards two different directions and remain in the braiding tool support.Improved thus stability.Simplify in addition installation, defined a position because give prominence to, on this position, can touch cover plate.

Projection is preferably surrounded cover plate outside, and wherein, projection is bonding with cover plate on the outside of cover plate.In other words, projection has the groove that is slightly larger than cover sheet thickness.Then cover plate is imported in this groove, thereby makes braiding instrument U-shaped ground in the zone of projection surround cover plate.Therefore provide three bonding planes in each braiding instrument between braiding instrument and cover plate, this has produced high stability.

Preferred arrangement interval part between cover plate, distance piece has thickness, the spacing between the narrow side of this thickness correspondence in braiding instrument FX.Cover plate links to each other with distance piece, and is for example same by bonding.Therefore cover plate not only is fixed on the braiding instrument, also is fixed on the distance piece, and cover plate can abut on the distance piece by plane earth.This makes the braiding tool support have high stability.

Distance piece preferably terminates in of rod member on the end of working region.Zone between the braiding instrument does not have to fill by adapter arbitrarily or by the element of distance piece.Especially when very high, can make more simply distance piece be equipped with the lateral margin of not moulding in the precision of braiding instrument, lateral margin is not charged into the gap between the braiding instrument.

Distance piece preferably is made of light metal or plastics.Therefore because the quality that distance piece brings change can remain on greatly very little.

Distance piece preferably consists of at least one backstop.In the time will weaving tool support and be installed on the braiding tool bar, backstop plays help in when location.

Stipulate in the preferred design of the first, cover plate is passed in the backstop guiding.But be necessary that in this case, for cover plate sets corresponding hole.But the advantage of this design is, also can with distance piece and cover plate form fit interconnect, this has further improved the stability of braiding tool support.

In the preferred design of the second, backstop is being stretched out from the space between the cover plate on that side of braiding instrument.In this case, distance piece has been configured to more simple profile.

In FX, the spacing between the narrow side is preferably less than the thickness sum of cover plate.Therefore the physical dimension that weaves tool support keeps very littlely.In fact cover plate can not cause physical dimension significantly to become large.

Cover plate is preferably made by the face shaped material of thickness in 0.1 to 0.8 mm scope.Cover plate in fact also can be configured to film.Although cover plate is very thin, also can be based on guaranteeing enough stability with bonding connection of braiding instrument.

At this preferably, the face shaped material is steel or plastics, uses according to circumstances fibre strengthening.The face shaped material must only have enough tensile strength, in order to can resist stress when braiding machine moves.

The braiding instrument preferably stretches out from cover plate and is 10 mm to the maximum.Therefore braiding machine only has shorter drift, and they can be out of shape in this drift.This expense during on the one hand with post processing remains on very little, for example when calibration braiding instrument.On the other hand, the stress of the bonding connection between braiding instrument and the cover plate is less, because only shorter lever arm is available.

The braiding tool support is preferably configured as about the plane symmetry between the cover plate.When the braiding tool support is installed, needn't pay close attention to the particular orientation that the braiding tool support weaves tool support relatively.

Description of drawings

Next by preferred embodiment and be described with reference to the accompanying drawings the present invention.In the accompanying drawing:

Fig. 1 is the front view of braiding tool support;

Fig. 2 shows the section B-B by Fig. 1;

Fig. 3 is the stereogram of embodiment after a kind of modification of braiding tool support;

Fig. 4 is the schematic cross sectional views by the braiding tool support of Fig. 3;

Fig. 5 shows the form of implementation after a kind of relative Fig. 4 modification; And

Fig. 6 has illustrated form of implementation after a kind of relative Fig. 5 modification with profile.

The specific embodiment

Fig. 1 shows the braiding tool support 1 with a plurality of braiding instruments 2, the braiding instrument 2 preset space length 3 ground settings of being separated by side by side and to each other.Braiding instrument 2 only can be seen narrow side 4 in Fig. 1.When will visible narrow side 4 is appointed as the front in Fig. 1, so corresponding narrow side 5 be located on the back side.

Narrow side

4,5 fingers are in the opposite direction.

By Fig. 2 and 3 as can be known, constructed by plane earth with the braiding instrument 2 that an aciculiform formula is arranged exists at this.They can be for example with there being the sheet metal punching of respective thickness to form.

The braiding tool support has two eyes 6,7, and bolt can be guided and be passed this two eyes, and braiding tool support 1 can be fixed by bolts on the braiding tool bar that is not shown specifically.It for example is 1 or 2 inch width that braiding tool support 1 has.Because eye 6,7 can be arranged as away from must be mutually, so braiding tool support 1 has good directed possibility at the braiding tool bar.

As especially can seeing among Fig. 2 and Fig. 3, braiding tool support 1 is configured to sandwich structure.The first cover plate 8 is bonding with the front narrow side 4 of braiding instrument 2.Narrow side 5 on the back side of the second cover plate 9 and braiding instrument is bonding.The address at " front " and " back side " is only explained in order to simplify in this use.Braiding tool support 1 is configured to and the plane symmetry between two

cover plates

8,9, can be towards illustrated direction or towards installing with the direction of 180 ° of direction as shown deflections.

Braiding instrument 2 has working region 10 and FX, and FX is made of rod member 11 at this.

Cover plate

8,9 is only bonding with braiding instrument 2 in the zone of rod member 11.For this reason, between rod member 11 and

cover plate

8,9, arrange respectively adhesives 12.

In addition, between two

cover plates

8,9, also be furnished with distance piece 13.Distance piece 13 has the thickness corresponding with the spacing in the zone of rod member 11 that is in FX between two narrow sides 4,5.Correspondingly with it is that two

cover plates

8,9 can be constructed on their whole development length flatly.

Cover plate

8,9 is connected with distance piece 13 plane earths, for example by bonding.But they also can be put and in succession a little or the line line ground of ining succession is connected with distance piece 13.

Cover plate

8,9 is made of relatively thin face shaped material.They can for example be configured to thickness in 0.1 to 0.8 mm scope, preferably at the steel membrane of 0.1 to 0.5 mm.As alternative,

cover plate

8,9 also can use plastics, and wherein, plastics are preferably used fiber, for example glass fibre or carbon fiber-reinforced.No matter be steel or fiber strengthened plastics, all have higher tensile strength, thus distolateral 4,5 and

cover plate

8,9 between bonding connection be enough to braiding instrument 2 is remained in the position reliably.

Distance piece 13 can be made of plastics equally.Also can use light metal.Eye 6,7 obviously also passes distance piece 13.

In pressing the design of Fig. 1 and 2, distance piece 13 has a pair of

backstop

14,15, that is the backstop on the front 14 and the backstop 15 that goes up overleaf.And another is to seeing in the drawings the backstop of one of them backstop 16 on the front, can be arranged in the zone at other edge that weaves tool support 1.The

corresponding hole

17,18 in the

cover plate

8,9 is passed in

backstop

14,15 guidings.They have facilitated the form fit between distance piece 13 and the

cover plate

8,9.

Distance piece 13 does not have profile at the edge that it faces braiding instrument 2, but smooth.Especially element and the projection in the gap 3 between the braiding instrument 2 of stretching into that does not have any distance piece 13.Gap 3 is empty between cover plate 8,9.

Backstop

14,15 can be positioned on the braiding tool bar in order to will weave tool support 1 as additional device.

Can see in Fig. 2, adhesives 12 is roughly given prominence to exceeding braiding instrument 2 ground between the inherent cover plate 8,9.This all is inevitably under many circumstances, but optional in principle.Can for example set up thus

cover plate

8,9 and braiding instrument 2 between bonding connection, that is, braiding instrument 2 is arranged side by side abreast with desired calibration in corresponding standard and cover plate 8 is equipped with adhesive film (or another kind of adhesives).When cover plate 8 being lain in the braiding instrument and lying on the distance piece 13, can form desired bonding connection.Need in case of necessity to apply certain pressure.Can repeat identical way at cover plate 9.

Fig. 3 shows the design after a kind of modification, and the difference of the design of it and Fig. 1 and 2 is, distance piece 13 has

backstop

19,20, and backstop is being stretched out from the space between

cover plate

8,9 on the side of braiding instrument.In addition, element identical or that correspond to each other marks with identical Reference numeral.

Braiding tool support 1 by Fig. 3 also has material hollow out 21, in order to alleviate quality.

Fig. 4 shows the side view by the braiding tool support 1 of Fig. 3.

Fig. 5 shows a kind of flexible program by the braiding instrument 1 of Fig. 4.The end that faces working region 10 of the rod member 11 of braiding instrument 2 on positive 4 has projection 22, then has projection 23 on 5

overleaf.Projection

22,23 forms respectively abutment face 24,25.

Abutment face

24,25 has from positive 45 the extensions to the back side, and this extension is greater than

cover plate

8,9 thickness.Therefore also can in

abutment face

24,25 zone, will weave instrument 2 and

cover plate

8,9 distolateral being bonded together.Obtain thus the bonding connection on two different directions, that is along the longitudinal extension direction of braiding instrument 2 and transverse to this longitudinal extension direction.This is so that intensity improves, and rigidity improves.

Fig. 6 shows the form of implementation after the relative Fig. 5 modification that weaves tool support 1 with side view.

As seen from the figure, the

projection

22,23 of braiding instrument 2 respectively has a groove 26,27, so

projection

22,23 can be surrounded

cover plate

8,9 in U-shaped ground.Groove 26,27 is constructed to be permeable to make

cover plate

8,9 to import with very little gap.This gap greatly to make the people adhesives can also be inserted

cover plate

8,9 and groove 26,27 wall between, thereby make braiding instrument 2 can with

cover plate

8,9 bonding along groove 26,27 wall.

As mentioned above,

cover plate

8,9 is very thin.In FX, that is on rod member 11, the spacing between the

narrow side

4,5 is greater than

cover plate

8,9 thickness sum.Correspondingly, the thickness of braiding tool support 1 is mainly determined by the width of braiding

instrument.Cover plate

8,9 counts thickness hardly.

Cover plate

8,9 can not be thicker than braiding instrument 2.

Braiding instrument 2 stretches out maximum 10 mm from

cover plate

8,9, preferably even only stretches out 5 mm or still less.Therefore this has formed a shorter free lever arm at braiding instrument 2, thereby makes the moment that causes the bonding connection between braiding instrument 2 and the

cover plate

8,9 to be unclamped can remain on equally very little.In addition, the associated directed necessity of the risk of braiding instrument 2 distortion and braiding instrument 2 is just very little.
