Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for mechanically forming twills on a group of warp threads drawn from a warp beam or the like in a textile machine, such as a gluing device. A hook blade movable in the vertical direction perpendicular to the plane of the yarn group and a sorting rod arranged correspondingly to the warping beam are provided, and the sorting rod is controlled by a mechanical adjustment device. It relates to a type of movement supported by a lift between the position and the cradle position.

The present invention also relates to a method for mechanically forming threads on a group of warp threads using an NR knitting machine.

Conventional technology? For example, a lottery device in practical use in the Federal Republic of Germany! tr
It is disclosed in Rakuto@8013381 publication. In this example, a hook braid or hook-shaped reed, which is common in the textile industry, is used, and the hook-shaped reed extends parallel to the plane of the warp group, It is supported to be movable in a direction perpendicular to the direction. In addition to the stepwise vertical movement, this arrangement requires horizontal interlocking (parallel to the plane of the warp group). Alternating stepwise movement in the vertical and horizontal directions requires expensive bearings. and a drive device.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a cradle device and method in which the cradle is carried out by means of a hook blade which is movably supported or driven only in the vertical direction, i.e. in the angular direction with respect to the thread group plane. It is to be.

Means for Solving the Problems According to the means of the device of the present invention which solves the above-mentioned problems, a tensioning device for horizontally moving a group of yarns held in a water plane for cradling is provided with a spacing between the hook blades. Keep g directly! It is arranged continuously. Advantageously, the tightening device comprises a presser foot m cooperating with guide rollers or the like.
between the thread group T guide roller and the presser foot,
They are tightened in rows and rows, and are moved as a whole in the horizontal direction.

In the hook JP removing device of the present invention, the hook blade is moved vertically up and down in stages at the time of Achinari Q.
The hook grips a predetermined thread which, according to the respective program, is moved to the hook by a horizontally movable tensioning device in the direction of rotation or in the opposite direction.

Sorting of the warp threads takes place in a fair-grained manner by means of a sorting rod located immediately in front of the hook blade in the running direction. According to the invention, it is possible to position the six threads reliably by holding each group securely by means of a tightening device directly but at a short distance behind the hook blade (seen in the running direction). be.

By moving the tightening device in the horizontal direction, each group can be brought into position as desired on one or the other side of the hook blade, so that during each subsequent vertical movement a given thread is driven from the hook. be done. Therefore, according to the present invention, JP removal is carried out by superimposing the stepwise movement of the hook blade and the horizontal reciprocating movement of the tightening device that holds the thread group.

Embodiment Next, the structure of the present invention will be specifically explained with reference to the embodiment shown in the drawings.

The stack and pick-up device shown in the perspective view of FIG. 1 is provided with a sorting rod 2 which is stretched over a frame 1Vc. These sorting rods 2 are pivoted as a whole into a lower, undetermined position or an upper, scale removal position. In the undefined position indicated by the arrow 4, each sorting rod 2 is held in relation to a group of threads 5 so that each group is guided completely through the frame 1 with as little force as possible. The one indicated by arrow 6? In the take-up position, the frame 1 is positioned such that the angle between each thread group portion 7 of the thread group 5 is as large as possible.

Furthermore, the cradling device according to the invention is provided with a hook blade, generally designated 8, and a tightening device, also generally designated 9.

The hook blade 8 consists of a frame 11 mounted movably in stages in the vertical direction 10. This frame 1
A rod 12 with a hook 13 is stretched inside the rod 1 . The hook blade 8 itself is constructed in a known manner (see, for example, German Utility Model Registration No. 8013381). However, in the embodiment shown, this hook blade is supported movably only in the vertical direction 10. As a drive device, a step drive device is used, which is schematically illustrated in the drawing.

The tightening device 9 connects the hook blade 8 in the running direction 15 of the thread group.
follows the movement of At the thread running position [14] of the thread-taking device, the thread group 8 passes, for example, a guide roller 16. The guide roller 16 is driven by a drive mechanism f! symbolized by an arrow 17. It is equipped with t. This drive device causes the guide roller 16 to reciprocate in a direction parallel to the plane of the yarn group 5 or 1 and perpendicular to the weaving direction @15. However, in this drive device, when thread #5 (a large number of threads are lined up parallel to each other) is tightened between the presser bar 18 and the inner side of the idle roller 16 by the presser foot 18, −? It is driven only by the filter in the pick-up position. This device is configured such that when driven, the guide roller 16 and the presser foot 18 pressed against the guide roller 16 reciprocate together in the direction of the arrow 1γ together with the thread group portion 7 fixed between them. ing.

When the cradle V device for cradle-taking is operated, first the frame 1 of the sorting rod 2 is rotated 60,000 times with the arrow in the range of the hook blade 8 to the extent that as large a distance as possible is obtained between each yarn group portion 7. It can be adjusted upward at n or swiveled. Furthermore, the tightening device t9 is activated. The thumb presser foot 18 is pressed against the guide roller 16, and the supply of yarn in the yarn running direction 15 is stopped. Then the hook blade 8 is moved upwards stepwise in the vertical direction 10, this vertical movement being combined with the horizontal movement of the tensioning device 119 holding the thread group 5.

Each exercise is performed as follows. A yarn twill is formed by moving the hook blade 8 into an alternating pressure and by lifting each of the four yarn layers. Each yarn layer is lifted one after the other by a sorting rod. After lifting the thread layer, the position of the hook blade is moved to the opposite side each time. Sorting releases the hook blade,
The alternating pressure is carried out by fixing and moving.
