DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide lever having at least one guide bar carried by a guide lever capable of reciprocating swing movement, for changing a basic position of a guide needle relative to a knitting needle. The present invention relates to a warp knitting machine in which the swing operation axis can be integrally displaced relative to the machine frame.

[0002]

2. Description of the Related Art A warp knitting machine of this type is known from DE-PS 959 939 having a single guide bar.
In this warp knitting machine, the guide lever is capable of swinging around a bearing consisting of a socket and a ball in a horizontal direction and a vertical direction with respect to the needle bed. Each of these bearings is carried by an intermediate member, which is fitted on an adjustment shaft which is supported in the machine frame. The adjusting shaft can be swung by about 45 ° by an adjusting lever, so that the guide needle can adjust its height from one place.

In a warp knitting machine readable from DD-PS44092, a guide bar is attached to a connecting rod of a four-bar linkage via an axial guide.
One of the links is displaceable relative to the machine frame by a cam. By turning the cam by about 180 °, the guide needle can be moved to a position suitable for inserting a warp.

[0004] The present invention relates to a warp knitting machine of the type mentioned at the outset in which the basic position of the guide needle can be changed relative to the knitting needle, which is of a particularly preferred construction in practice. The purpose is to provide.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided, in accordance with the present invention, a guide lever having a torsional stiffness, coupled to a common rocking shaft, and having at least one via an axial guide.
This is solved by an arrangement in which the rocking shaft is supported on the machine frame via an eccentric bush, which carries two guide bars and whose rotation is adjustable.

According to such a structure, the desired displacement of the guide needle is performed by the swing shaft which can be common to all the guide bars. Since the axial offset of the guide bar is absorbed by the axial guide,
Ball bearings can be omitted. In operation, the basic position of the guide needle is changed, for example, to the stitch escape position of the knitting needle by simply turning the eccentric bush at a position easily accessible.

[0007] It is preferable that the eccentric bush is rotatable and fastened on the swing shaft. With this configuration, rotation and tightening can be easily realized structurally.

A configuration in which the eccentric bush has a groove and is surrounded by a grooved tightening ring is also a desirable configuration. Because the clamping ring surrounds the eccentric bushing, the clamping ring is easily accessible.

Preferably, the adjustment ring provided with the mark (eye mark) has a torsional rigidity and is connected to the eccentric bush. According to such a configuration, each rotation angle position is readable, and can be repeatedly adjusted to the same position as needed.

When the adjusting ring is formed by the tightening ring, a further simplified configuration is obtained.

[0011] In one preferred embodiment, at the end of the guide lever remote from the at least one guide bar,
The present invention has a configuration in which a drive for a swing operation is performed by a connecting rod (tappet) via a joint eye. In such a configuration,
When adjusting the eccentric bush, the joint eye becomes the point of action for the guide lever, and even if the adjustment is made, the position is only slightly changed. This is tolerable in the case of driving by a connecting rod.

Hereinafter, the present invention will be described in detail based on a preferred embodiment shown in the drawings.

[0013]

1 shows only a knitting needle 2 and a guide needle 3 in a knitting area 1 of a warp knitting machine. The guide needle 3 is a needle with a hole, and the guide needle 3 is carried by guide bars 4, 5 and 6. The guide bars 4, 5, and 6 are provided with axial guides 7,
8 are respectively connected to guide levers 9. The guide lever 9 is fixed to a swing shaft 10. The swing operation is performed via a connecting rod (tappet) 11 projecting from a mechanical bed (not shown). In the mechanical bed, the connecting rod 11 is, for example,
It is driven by a cam which is surrounded by a bearing ring. This connecting rod 11 is provided with guide bars 4, 5,
It acts on a joint eye (connection hole) 12 arranged at the distal end 13 of the guide lever 9 on the side remote from 6.

In this structure, the guide needle 3 performs a swing operation, and this operation causes the guide needle 3 to swing.
Moves from the underlap operation position to the overlap operation position, and returns to the underlap operation position again.
By the way, in order to change the basic position of the guide needle 3 (the basic position with respect to the knitting needle 2) occupied by the guide needle 3 when the stitch escape position is changed during the knitting cycle, the following configuration is provided. ing.

The oscillating shaft 10 carries an eccentric bush 14 having a groove 15. The eccentric bush 14 is surrounded by a tightening ring 16 at a part of its entire length in the axial direction. This tightening ring 16
Has a groove 17 and a tightening screw 18. Further, the tightening ring 16 has torsional rigidity and has an eccentric bush 1.
4 and is rigidly connected to the clamping ring 16.
Is a mark (eye mark) 19 in the form of an angle scale on the side surface.
It has. The mark 19 functions in combination with the pointer 20 provided on the machine casing 21. The portion of the eccentric bush 14 that is not surrounded by the tightening ring 16 is
It is supported so as to be rotatable in the intermediate wall 22 of the machine frame 21.

In order to give a new position to the guide needle 3, the warp knitting machine is moved to the stitch escape position. Next, the tightening ring 16 is loosened and turned to a new position readable by the mark 19. The swing shaft 10 is displaced accordingly. Next, the fastening screw 17 is tightened again. Thus, the eccentric bush 14 is fixed to the swing shaft 10. Subsequently, the warp knitting machine can be operated at the newly adjusted position of the guide needle 3.

[0017]

According to the present invention, it is possible to provide a warp knitting machine in which the basic position of the guide needle can be changed relative to the knitting needle with a particularly preferable structure in practical use. .
