Description

The sley bar of knitting machine

Technical field

The present invention relates to a kind of sley bar of knitting machine, it has a plurality of grooves and is used to be placed into coil element, and these become coil element to be arranged side by side mutually along the longitudinal tensile strain of sley bar, and wherein each groove has a bottom land, two groove sides and a notch.

Background technology

Such sley bar generally is the part of warp knitting machine.But they also can be applied on other the loop-forming textile.Become coil element preferably compound needle or other crochet hook.

Below be that the present invention will be described for example with the crochet hook.

Many crochet hooks are generally arranged in knitting machine.The crochet hook number of every meter sley bar length can reach 500 to 2000.Crochet hook certain wearing and tearing that are in operation.They that is to say sometimes and must change.

Crochet hook is arranged in the groove of sley bar.At this moment importantly: crochet hook is arranged mutually with the scale division of regulation.Also should guarantee to be parallel to the straight line centering of the longitudinal tensile strain of sley bar later on inserting crochet hook.

Because crochet hook is a bulk article, have only when allowing to accept certain tolerance, just may be with expense crotchet in the next life pin that can represent.This tolerance for example can be certain thickness difference, and this may be to be criticized when making by different plates when crochet hook to form.This causes these grooves generally must do to such an extent that be slightly larger than the thickness of crochet hook.Though this allow to make crochet hook to take out easily and the groove of packing in, having caused after crochet hook inserts sley bar has certain clearance.

Therefore in DE4414703C2, just advise that be provided with projection on the needle handle of crochet hook, they have produced certain interference with respect to receiving slit.When being pressed into these pins in the groove, these projectioies just push a little or the compression groove side on material, and pin seamlessly is positioned in the groove.Certain this no intermittence can not keep the long time or will often change.When producing in enormous quantities inevitably: these projectioies always are located on the same position.When changing such pin projection is entered on the position, the projection that is positioned at crochet hook there before on this position has been pushed material, so has occurred a kind of closely spaced risk here again.

Summary of the invention

Even task of the present invention is also to make into coil element to realize gratifying cooperation after repeatedly being replaced with coil element in sley bar.

This task solves for the sley bar of the described pattern of beginning as follows: groove is at the width at the notch position width greater than groove bottom part.

The side that the groove of sley bar is not arranged in parallel, as in the past common, but these grooves that is to say that the width in opening is greater than the position, back in front in the position, just the width in the position of bottom land.The crochet hook that is designed to corresponding manner location automatically then in insertion groove the time that is to say with this groove crochet hook is always abutted on the groove side, thereby it can seamlessly be remained in the groove from its front when stopping power accordingly.That is to say the groove dividing plate distortion that both needn't make between groove, also needn't squeeze the material that pushes away groove dividing plate or crochet hook.But can with the so-called no abrasion of crochet hook and sley bar assemble.

Preferably realize by a surface that transition from big width to less width, this surface are arranged on a part of degree of depth of groove side at least and laterally inclined or crooked to another groove on direction from notch to bottom land with respect to another groove side.For one tilt or curved surface realize a kind of little laterally offset then in the time and the time first with the side of crochet hook and groove contacts side surfaces with the crochet hook insertion groove, that is to say another groove side of another contacts side surfaces until crochet hook.Therefore realized that contact and crochet hook on two sides of crochet hook seamlessly and reliably join seat in groove.

This surface preferably is stretched over bottom land always.Therefore realize the contact of maximum possible and when inserting crochet hook, in groove, realized corresponding big guiding.

More preferably, the surface of this inclination has at least two part surfaces, and they have different inclination angles.Therefore crochet hook being inserted and is fixed in the groove can also design better under special situation.

Groove side more preferably with the front of the sley bar layout that meets at right angles.This groove side has just constituted the position that crochet hook will be aimed in groove in this case.Perhaps crochet hook is enclosed in the groove, makes the contacts side surfaces of it and arranged at right angles, then crochet hook is pushed in the groove, always till it touches the side of inclination.Crochet hook seamlessly is matched with in the groove in this case.If crochet hook is inserted, make it at first touch the side of inclination, then by making it push vertically arranged side to, till it is attached on the vertically arranged side with contacting of inclined plane.Also guaranteed gapless cooperation in this case.

Stipulate in a kind of alternative design: two groove sides have the surface, and they tilt mutually or become crooked.Become coil element to cause with first just the contacting of groove side in this case: the lopping element is displaced sideways a small distance, till it and another groove contacts side surfaces.This has also guaranteed gapless cooperation.

Two groove sides more preferably have surface section in the scope of Breadth Maximum, their layouts that is parallel to each other.That is to say the gradient that just in a part scope, has made full use of one or two side.This is enough to guarantee that crochet hook realizes gapless cooperation in groove.

Preferably at least one groove insert one and become coil element, this one-tenth coil element has fastening a section of being located in the groove, and it comprises a front, a back side and two sides, wherein fastening section in front the width in the scope greater than the width in the position overleaf.Become the cross section of coil element to be matched with the cross section of groove in this case.Groove can be filled with the one-tenth coil element.This makes into coil element and preferably is fixed in the groove possibly.

The side preferably has the surperficial identical orientation as the groove side at least in the branch surface.In fact these surfaces can recline by plane earth mutually in this case, have therefore guaranteed the fastening high-stability of crochet hook in groove.

Become coil element more preferably in groove, to give prominence to exceeding highly of predesignating.Its advantage is: can be by means of a clamping device, and for example a top cover will become coil element to be fixed in the groove.

Equally also advantageously: between the back side of bottom land and one-tenth coil element, be provided with a safe spacing of predesignating.This safe spacing is slightly less than and exceeds height.Guarantee on the one hand by this safe spacing: become coil element to be pushed in the groove abundantly, so that seamlessly abut on two groove sides, when excessive big power occurring, limited on the other hand and become coil element to enter stroke in the groove, thereby when big like this power occurs, the groove dividing plate between groove can not deformed in objectionable mode.Become coil element to run into bottom land exactly when big like this power, that just no longer continues to have moved.

The specific embodiment

Fig. 1 has represented the intercepting part of the sley bar of a knitting machine that is not shown specifically with having an X-rayed.Such sley bar necessarily can have several meters length.

Sley bar 1 has many grooves that are arranged side by side 3 for 2 li a height section, and these grooves are parallel to each other and are arranged side by side on the longitudinal tensile strain of sley bar 1.Groove 3 is separated from each other by groove dividing plate 4.

In groove, be provided with crochet hook 5.Shown just has crochet hook 5 in two grooves.But all grooves 3 all are equipped with crochet hook 5 usually.

Crochet hook 5 shown in Figure 1 has been done expression with two different lines of vision in Fig. 2.Each crochet hook 5 has a needle handle 6, and it has a fastening position 7.Crochet hook 5 usefulness fastening positions 7 are fixed on 3 li of the grooves of sley bar 1.

A common syringe needle 8 is connected in an end of needle handle 6, and this syringe needle is designed to hook, wherein in the mode of not representing in detail a slide bar can be arranged, and it can make hook 9 close, and this moment, hook 9 will pass coil with yarn.Crochet hook has a pin heel 10 on opposite ends, and it has a projection 11, and this projection acts on below the height portion section 2, so that crochet hook 5 is fastened on 1 li of sley bar by way of parenthesis.

In order to carry out following explanation, more precisely its fastening part section 7 is defined a front 12, the back side 13 and two

sides

14,15 for crochet hook 5.Positive 12 is from the face of 1 li directed outward of sley bar after loading onto crochet hook 5.The back side 13 is those faces that are inserted into 1 li of sley bar the darklyest.

As seen from Figure 4, two

sides

14,15 of fastening position 7 mutually and not parallel sensings, but they tilt on the direction at front 12 to the back side 13 mutually at one.The cross section of crochet hook 5 in fastening position is V-arrangement in fact.

Each groove 3 has a bottom land 16, notch 17 and two

groove sides

18,19 with corresponding manner, and wherein the cross section of groove 3 is matched with the cross section of the fastening position 7 of crochet hook 5.The inclination angle of

side

14,15 that is to say with the inclination angle of

groove side

18,19 harmonious.

Consequently: if with 3 li of crochet hook 5 insertion grooves, crochet hook 5 is with regard to self-centering.A side in two

sides

14,15 when 3 li of insertion grooves go just with two

groove sides

18,19 in a groove contacts side surfaces, and when crochet hook 5 further being pushed 3 li of grooves, move to the side slightly, until another

side

15,14 and another

groove side

19,18 contacts.Make crochet hook 5 automatically the centrally aligned of groove 3 also seamlessly be realized the location there in this case.Need when being inserted sley bar 1, crochet hook 5 not make groove dividing plate 4 or part wherein carry out certain distortion.
