Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a Garoon crochet knitting machine according to the preamble of claim 1.

[0002]

2. Description of the Related Art A Garoon Crochet knitting machine of the type described at the beginning is disclosed, for example, in International Application Publication PCT / WO85 / 0491.
Many are known from 1 and the like. The Garoon crochet knitting machine described in this international application has a pattern yarn guide which is arranged similar to the warp yarn guide, in other words in front of the knitting needle. The warp yarn knit product is inserted into a knitting needle while being placed on the warp yarn in a portion where a pattern is generated, and is knitted together. In areas where the pattern is not formed, the controllable thread retainer prevents the insertion of the pattern thread into the knitting needle and thus the weaving of the pattern thread. The thread retainer is controlled, for example, via a Jacquard machine. This Garoon Crochet machine is relatively complex.

[0003]

SUMMARY OF THE INVENTION The object of the invention is to improve a Garoon crochet machine of the type mentioned at the outset.

[0004]

According to the present invention, the above-mentioned problems are solved by the features described in the characterizing part of claim 1.

By virtue of the fact that the pattern thread guides are arranged above the knitting needle track and individually controllable by the jacquard machine, only the pattern thread guides operate at the knitting point, so that a controllable thread retainer is no longer necessary. .. This provides a simplification of the Garoon Crochet machine, especially in the knitting area. This also has an advantageous effect on the patterning of manufacturable knit products, the service life of the Garoon Crochet machine, in particular the operating speed.

Advantageous embodiments of the Garoon Crochet machine are described in claims 2 to 12.

The patterned thread guide can be formed as a thread needle as claimed in claim 2 or as a pipe needle as claimed in claim 3. A particularly simple arrangement of the pattern thread guide on the pattern needle guide bar is described in claim 4.

It may be advantageous to limit the misalignment of the pattern thread guide as described in claim 5. The pattern thread guide can be moved in and out of the knitting needle track under one angle, but the embodiment as claimed in claim 6 is advantageous.

The deviating curvature of the pattern thread guide can be of different types, but the embodiment of claim 7 is advantageous. Due to the cooperation with the pushing element, the pattern thread guide can likewise have a different structure, so that for example a cam can be mounted on the shaft of the pattern thread guide.

A particularly simple structure of the pattern thread guide is claimed in claim 8.
It is described in.

The pushing element may be guided along a component which is independent of the pattern needle guide bar. However, the embodiment as claimed in claim 9 is advantageous.

In this case, it is advantageous if the pushing element according to claim 10 is bias-tensioned toward the knitting needle trajectory.

The embodiment of claim 11 is particularly advantageous. This is because in this case the relative movement of the controlled pushing element with respect to the pattern needle guide bar is avoided.

It is possible to increase the variety of patterns by the embodiment described in claim 12.

EXAMPLE A Garoon Crochet knitting machine shown diagrammatically
(Haekelgalon maschine) has a knitting needle row member 2. One row of knitting needles 4 in the knitting needle guide bar 2 (Wirknadelbarre)
(Wirknadeln) are arranged in parallel. The knitting needle guide bar 2 reciprocates the knitting needle 4 in the longitudinal direction as shown by an arrow 6. The knitting needle 4 in FIG. 1 is shown in the forwardly moved position.

The knitting needle 4 is guided into a reed 8 (Abschlagkaum). A guide plate 10 is placed in front of the comb 8. The guide plate 10 forms a guide gap 12 together with the reed 8. The finished knit product passes through the guide gap 12 and is not shown in the drawing as a detaching device (Abzugsvorri).
chtung).

In front of the knitting needle 4, a warp thread guide 16 (Kett
fadenfuehrer) is placed. The warp thread guide 16 is formed as a stitch needle (thread guide needle), and the warp thread guide bar 18 is provided.
It is fixed to (Kettlegestange). The warp thread guide bar 18 causes the warp thread guide bar 16 to move.
It reciprocates in the direction of 8 and makes a swiveling motion from a high position above the knitting needle plane (FIG. 1) to a low position below the knitting needle plane. Therefore, the warp thread guide 16 can insert the warp thread 20 into the knitting needle by the motion of enclosing the knitting needle 4.

A weft guide bar 24 (Schusslegestan) having a weft guide 26 used for feeding the weft 28.
ge) is fixed above the knitting needle plane to a vertically movable support member 22. The weft thread guide 26 is formed as a pipe needle 28.

Another thread guide 34 having a thread guide 34 formed as a thread needle 36 is fixed to the support member 22. The thread guide 24 is used to supply the rubber thread 38.

Weft thread guide bar 24 and thread guide bar 32
Between the support members 22, the patterned needle guide bar 40 (Muster
nadelbarre) is located. Patterned needle guide bar 40
Carries a pattern thread guide 42. Pattern thread guide 42
Is fixed to the patterned needle guide bar 40 such that it can be bent laterally. The stopper 44 limits the lateral displacement curve of the pattern thread guide 42 (FIGS. 2 to 4).

The pattern thread guides 42 each have one lateral offset curve 48 on its shaft 46. One push-back element 50 meshes with each of the laterally-displaced curved portions 48,
The pattern thread guide 42 is caused to have a laterally offset curve.

The push-pull element 50 is a cam. The cam is fixed to the push-pull needle plate 52. The push-pull needle plate 52 is a tow knitting string 5.
4 to a jacquard machine 56. The compression spring 58 presses the pushing element 50 against the plane of the knitting needle. The traction braids 54 are guided through eye plates 60 (Chorbrett) and are each connected to one spring-mounted needle plate 62 (Platine).

The needle plate 62 is vertically guided in the needle plate bottom surface 64. Knives 66 and 68 that are driven up and down are arranged on the needle plate bottom surface 64. The magnet 70 is also arranged on the needle plate 64.

Each needle plate 62 has a carry hook 72. Unless the magnet 70 is biased, the entrainment hook 72 causes the needle plate 62 to engage the associated knives 66 and 68 by its own spring force.

When the magnet 70 is urged, the associated needle plate 62 is disengaged from the movement trajectory of the associated knives 66, 68 against its own spring force, so that the knives 66, 68 are not entrained by the associated needle plate 62. Be moved up and down. Therefore, the pattern yarn guide 72 for the lateral deviation curve of at least one knitting needle pitch
Therefore, the associated magnet 70 is not biased, so that the associated needle plate 62 is locked by the associated hook 72 by the associated hook 72 and is carried upward.

This is 1 as can be seen from FIGS.
This results in a lateral offset curve of the associated pattern thread guide 72 of only one needle pitch.

The support member 22 can be moved up and down as shown by an arrow 74 by a driving device (not shown). The vertical movement takes place in a direction 76 substantially perpendicular to the plane of the knitting needle 4.

The support member 22 is lowered when the knitting needle 4 is moved from the rear position to the front position. As a result, the yarn guided from the yarn guide 72 through the supporting member 22 is
And is engaged in the needle path between the knitting needles 4 during the forward movement of the knitting needles 4 as can be seen in FIG. At the position where the knitting needle 4 is moving forward, the warp yarn is placed around the knitting needle 4 so that the yarn which is lowered by the yarn guide 72 is fixed by the warp yarn.

During the return movement of the knitting needle 4, the yarn guide 72 fixed to the support member 22 is also lifted upward.
When the support member 22 is in the high position, the thread guide 72 changes its position. In other words, before the knitting needle 4 is moved from the retracted position to the forward position, the thread guide 72 is laterally offset and curved in the desired direction by the guide bar or push-back element and is lowered again by the support member 22.

By means of the pattern thread guide 42 and the jacquard machine 56, each individual pattern thread guide 42 is curved laterally by at least one needle guide by the associated push-pull element 50 (FIGS. 3 and 4). 4), or as shown in FIGS. 2 and 3, when the pattern is not formed, it is not displaced.

The jacquard machine 56 and the support member 22 have the knife 66 or 68 and the support when the pattern thread guide 42 is controlled, that is, when the associated needle plate 62 is engaged with the associated knife 66 or 68. The members 22 move in a substantially synchronous manner, so that the push-back element 50 causes the pattern needle guide bar 40 to move.
Also, the drives are aligned with each other so as not to move relative to the pattern thread guide 42 when the pattern thread guide 42 moves up and down.

To further increase the pattern versatility, the pattern needle guide bar 40 is additionally controlled in the direction of the pattern needle guide bar 40 by at least one needle pitch in a known manner not shown by the pattern thread guide 42. This is possible because it can be reciprocated. This makes it possible to form an overlap of 1 to at least 3 stitches.

In the illustrated embodiment, the support member 22 and, by extension, the pattern needle guide bar 40 and the pattern thread guide 42 are also the knitting needles 4.
Move perpendicular to the plane of. However, the thread guide 42 is ± 3
It is also possible to arrange the arrangement so that it is moved relative to the plane of the knitting needle 4 at an angle which deviates from the vertical by 0 °. In the illustrated example, the pattern thread guide 42 has a thread needle, but FIG.
It is also possible to have a pipe needle as shown in.
