Abstract

Disclosed is a warp knitting machine for producing at least one ribbon, comprising a knitting needle (8), warp thread placing elements that are associated therewith, and a weft bar (12) with at least one weft thread guide (14). In order to improve said warp knitting machine, the weft bar (12) is hingedly connected to rocker arms (20) on both sides such that the weft thread guide (14) follows a circular arc-shaped path (30) in order to insert the weft thread (6) at the knitting point.

Description

Warp knitting machine

Technical field

The present invention relates to a kind of, warp knitting machine of being used to make at least one band as described in the preamble according to claim 1.This warp knitting machine is particularly useful for making elastic webbing here.

Background technology

For example by the warp knitting machine of the EP 0158652 known many kinds of described types of preface.Wherein, the wefting insertion bar can along its vertical reciprocating motion be bearing in the sliding sleeve in the rocking bar of side, this back and forth guides rocking bar with respect to knitting position when swing.The shortcoming here is that for wefting insertion needs two different drivers, exactly, a driver is used for the wefting insertion bar along its reciprocating motion longitudinally, and another driver is used for the oscillating motion of rocking bar with respect to knitting position.This causes driving expensive and that be difficult to coordinate.In addition, the slip guiding of wefting insertion bar in rocking bar easily causes wearing and tearing, and this especially occurs under the situation of dust hazard common in this working environment.

Summary of the invention

Technical problem to be solved by this invention is to overcome above-mentioned shortcoming, the warp knitting machine of the described type of improvement preface.

This technical problem solves by the described feature of the characteristic of claim 1 in the warp knitting machine of the described type of preface.Because the wefting insertion bar is at two ends and swing arm is hinged is, make the weft yarn guide member implement the circular arc track in knitting position in order to penetrate weft yarn, so not only the weft yarn guide member arrives the conveying of knitting position, and the weft yarn guide member all carries out along unique movement locus along the lengthwise movement of knitting needle.So for desired these motions only need single driver, single driver is cheap, adjustment is simple and be convenient to control.In addition, the hinged eliminating of wefting insertion bar and swing arm is slided and is guided, thereby not only reduces wear, and improves flexibility and reduce driving force.The described hinged atmosphere that can also prevent dust-laden more simply.

The design that the present invention is favourable has been described in claim 2 to 7.

The design by claim 2 of warp knitting machine is favourable, and in view of the above, the pin joint of wefting insertion bar on swing arm can be along its vertical adjustment.Can adjust the length of wefting insertion thus.Design by claim 3 also is particularly advantageous, and in view of the above, the wefting insertion bar is fixed at two ends on the vertical edges of curved bar, and another horizontal sides of curved bar and swing arm are hinged.Especially be favourable by further developing of claim 4, in view of the above, the wefting insertion bar can be along the vertical edges adjustment of curved bar for this reason.Can adjust on the one hand thus the wefting insertion bar with respect to knitting position and thereby the distance of knitting needle, and thereby can adjust the weft yarn guide member on the other hand with respect to knitting position and thereby the distance of knitting needle.

By claim 5, swing arm is hinged on the frame.

Design by claim 6 also is favourable, and in view of the above, the weft yarn guide member can be along vertical adjustment of wefting insertion bar, thereby can accurately adjust the weft yarn guide member in knitting position.

Warp knitting machine can be designed for makes the wall scroll band, or also can be designed for and make two or many bands arranged side by side simultaneously.

The driver that relates to the wefting insertion bar has various possibilities.Claim 7 has illustrated a kind of simple especially form of implementation by crank driving mechanism driving wefting insertion bar, and its crank directly or indirectly is connected with the wefting insertion bar by coupling bar.

Description of drawings

Describe the form of implementation of warp knitting machine below in detail by accompanying drawing, wherein:

Fig. 1 represents warp knitting machine disappearing fiber schematic front view, and wherein the driver crankangle is 0 ° or 360 °; And

The wefting insertion of the warp knitting machine of Fig. 2 to 4 presentation graphs 1 is in different phase, and wherein crankangle is 90 °, 180 ° and 270 °.

The specific embodiment

Fig. 1 schematically illustrates warp knitting machine disappearing fiber front view.This warp knitting machine is designed to make two bands 2 arranged side by side simultaneously.Article one, this band is by knitting warp thread, and so-called tasselled 4 are formed, and they are connected to each other by weft yarn 6 horizontal expansion, that inweave.In order to make tasselled 4, warp knitting machine contains some knitting needles 8, and this knitting needle is guided in push jack 10.The wefting insertion bar 12 that is fixed on the weft yarn guide member 14 is used to penetrate weft yarn 6.Rightly, weft yarn guide member 14 can be vertically fixed on the adjustable position along wefting insertion bar 12 by fishbolt 16.

Wefting insertion bar 12 is hinged by curved bar 18 and swing arm 20 at two ends.Swing arm 20 itself is contained on the support 24 by bearing 22 respectively pivotally, and support 24 is connected with frame 26 again.Swing arm 20 can be respectively at the vertical line 28 both sides angle of revolution α with respect to knitting position.By gyration, weft yarn guide member 14 is implemented circular arc tracks 30, and the string of this circular arc track is equivalent to weft yarn guide member 14 from the length X of 2 one sides to the opposite side moving movement.Y represents the height of circular arc track 30 above knitting position of weft yarn guide member 14.

In order to adjust the distance of weft yarn guide member 14 to knitting position, wefting insertion bar 12 is connected with the limit 34 of curved bar 18 perpendicular to the disappearing fiber orientation by regulator 32 respectively in both sides.Regulator 32 comprises an elongated slot 36 in limit 34, wherein fishbolt 38 is used for the location.

Can adjust the moving movement of weft yarn guide member 14 by another regulator 40.This regulator 40 comprises a hinge 42 in the horizontal sides 44 of curved bar 18, this curved bar is connected with swing arm 20.For this reason, hinge 42 can move in the elongated slot 46 of swing arm 20, and can be fixing by fishbolt 48.Can increase or reduce the radius of circular arc track 30 above knitting position thus.

Can imagine different forms of implementation in order to drive wefting insertion bar 12.Use a crank driving mechanism 50 in the present embodiment, its crank 52 is connected with one of two swing arms 20 by coupling bar 54 for this reason.Fig. 2 to 4 represents to penetrate along knitting needle 8 each stage of weft yarn 6, that is the crankangle of this moment is 0 ° or 360 °, 90 °, 180 ° and 270 °.
