The present invention is arranged in a circular and two rows around an inner partial heald and an outer main shaft, and a drive device consisting of a belt fastening device or the like is combined with the partial healds on a heald slide frame in each case. The heald slide frame is in each case supported on a rotating cam by a driven device, i.e. a counter roller, and the heald slide frame moves up and down on a vertical guide device, thus providing a wave motion between the inner partial heald and the outer partial heald. A loom, in particular a circular loom driving device, for producing a loom.

According to the prior art (German Patent No. 2422967), a slide piece that moves up and down with a heald slide frame is used in the device of this type, and the slide piece is fixed to the heald slide frame.

However, since such a sliding device is extremely abrasion, it is difficult to reduce the abrasion even when a large amount of lubricating oil is used. Therefore, such a device is not a mechanically satisfactory device, and requires a large amount of lubricant to use the device to some extent.

Therefore, the problem to be solved in the present invention is to provide a heald drive device that is substantially free of maintenance, frequently used, and safe in operation by eliminating these disadvantages of the prior art.

According to the present invention, this object is achieved by supporting a heald slide frame driven to the plate-shaped cam by the driven device to move up and down on at least one vertical guide rail by at least three side guide rollers.

According to the present invention, two vertical guide rails spaced apart from each other are supported to support heald slide frames with these guide rollers between the vertical guide rails, or a guide rail is provided concentrically with the heald slide frame. It is possible to allow the guide rollers of the heald slide frame to engage on both sides on the guide rail.

If the guide rails form the shape of their rotational surfaces and occupy the occlusal side shapes on these guide rollers (in this case the shape of the rotation on the guide rails is blocked so that they interlock with the concave shape of the guide rollers and vice versa) Or taper the shape of the rotational surface on the guide rail toward one point or form a groove to engage with each occlusal shape on the guide roller (and vice versa).

In order for the heald slide frame to be continually accurate, low noise and non-abrasive, it is preferable to have a cam shape that changes in the axial direction. The cam shape is formed in the form of a flange protruding radially from the mantle of the plate-shaped cam. On the plate-shaped cam, a counter roller-type following device carried by the heald slide frame is supported, and the cam flange is also supported. It is preferable to form a taper on the rotating surface of which conically extends outwardly and interlocks with the outer surface of the opposed conical structure of the opposing roller on the heald slide frame.

At least the guide roller is preferably made of plastic or aluminum having a hardened steel or abrasion resistant coating for the manufacture of a heald resistance driving apparatus according to the present invention that does not have a maintenance cost.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The circular loom shown in FIG. 1 is originally mounted on the loom base 1 in a known manner, which supports the circular frame conveying machine 2. The circular frame conveying machine 2 conveys the frame part 5 for supporting the circular body reed 3 loom short circuit switch 4 and the infant 6. The baby 6 is arranged in a circle in a known manner around the main axis 8 of the loom as described below.

A crawler electric machine 14 is also located at the point of extraction. In the circular loom shown,

A pulling roller 15 for pulling 7) is shown, and a pulling roller 16 for pulling a slope is also shown on the left end. The inclination 7 is divided into two inclination bundles and is drawn out by the inclination failure stage in a known manner, which is not shown in detail in the drawings. To form the woven opening, one of the inclined bundles is raised while the other bundle is guided down from the height of the weaving plane through a change in the so-called opening movement, so that the upper inclined bundle 7 'and the lower inclined bundle are To form. In the so-called stacked openings or the multi-layer openings, wefts (not shown)

A shuttle 30 with bobbin passes through a horizontal circular passage. Thanks to the circular motion of the drum, the wefts released from the weft bobbin are transmitted on the edge 13 of the circular fabric so that the weaving yarn is woven into the fabric. Subsequently, the fabric can be drawn into a flat fabric if it is pulled out in a circle.

In order to perform the above-mentioned opening forming operation, a large number of infants 6 are arranged in a circle around the main side 8 of the loom adjacent to the outer surface of the circular body 3. As shown in FIG. 1, each infant 6 is comprised of the partial belts 24 and 25 formed, for example by belt strands. For example, for this purpose, an endless belt may be guided through each of the guide pulleys 22 and 23, which are freely rotatable at the top and bottom of the frame 5, respectively. It may be.

口)(26)이 있는데 이 급사구를 통하여 경사 다발(7') 또는 (7＂)중의 어느 하나 또는 다른 경사(7)이 당겨진다. 벨트(24) 및 (25)를 마주보게 상하 역방향으로 교호운동 시킴으로써, 전술한 양 경사 다발의 개구 운동 변화가 발생한다.The inner belt 24 and the outer belt 25 each have a yarn feed hole.

There is a mouth 26, through which the inclined bundle 7 'or the other inclination 7 of the inclined bundle 7' or 7 'is pulled. By alternating the belts 24 and 25 so as to face each other in the up and down directions, the above-described change in the opening motion of both inclined bundles occurs.

For such an alternating movement, the inner belt 24 may be firmly connected to the so-called drum sliding portion 29 which slides up and down on the motion control device below the feed hole 25. Protruding from the vertical sliding part 29 is the counter roller 3 supported by the cam-shaped flange 32 and rotating about the main shaft 8 of the loom on the corresponding plate-shaped cam 33.

Since the structure of the circular loom to the extent described so far corresponds to the prior art, no further detailed description of such circular loom is necessary.

The problem to be considered with respect to the circular loom of the above-described configuration is to arrange an apparatus (means) for generating a change in the opening motion on both inclined bundles.

However, known devices in the form of rod-like slide pieces which slide the heald slide frame up and down, for example, fixedly fixed to the heald slide frame, have a very large amount of wear and cannot be actively reduced even with this amount of lubricant. The facts came to light. Thus, such devices are expensive in terms of high machine life cycles. Moreover, the slide guide tends to overturn. This results in a large amount of assembly required for some practicality.

In the present invention, in order to take measures to remedy such drawbacks, the plate-shaped cam 33 and the opposite roller 31 are formed on the cam-shaped flange 32 of the plate-shaped cam 33 according to FIGS. 2 to 6 of the present invention. A heavily connected heald slide frame 29 is supported by at least three side guide rollers for vertical movement on at least one vertical guide rail. This will be described in detail below.

According to the present invention, it is compelled to say that this method does not depend on how the infant is made to move by the heald slide frame 29. For example, instead of the above-described belt-type partial carp, a hard-part carp can be provided, and the vertical motion of this hard-part carp is connected to this hard-part carp on one side and heald slide frame on the other. The one side, which is firmly connected to, is produced by the rigid partial belt means.

As can be seen from FIG. 2, FIG. 3 and FIG. 4, according to the first embodiment of the present invention, two vertical guide rails 40 'spaced apart from each other are provided and a heald slide frame ( 29 is supported by the guide roller 41 '.

In order to continuously move the heald drive frame 29 in a precise, low noise and practically non-wearing manner, a cam-like flange protruding radially from the sheath of the plate-shaped cam 33 and axially changing the plate-shaped cam 33. If 32 is present, it is preferable to support the driven device in the form of an opposing roller 31 conveyed by the heald slide frame on the cam flange.

As shown in detail in FIG. 3, the rotating surface 32 ′ of the cam-shaped flange 32 extends outwardly conical to interlock with an outer surface opposite to the conical structure of the opposing roller 31 on the heald slide frame 29. There is a taper.

As can be easily seen in the drawings, such a structure is a concept of the invention to ensure that the small size of the device, the low cost, precise and practical noise generation, easy to maintain continuous operation.

Of course, other modifications are possible in this regard within the framework of the basic inventive idea of the invention.

For example, according to FIGS. 5 and 6, a guide rail 4 extending toward the center of the heald slide frame 2 is provided, and the guide rollers 412, 413 or 411 of the heald slide frame 29 are provided on the rail. Occlusion on both sides.

In this regard, the shape of the rotating surfaces 401, 402, 403 on the guide rail 40, for example, may taper outwards to a point or form a groove to engage each bite on the guide rollers 411, 412, 413. Or the reverse structure.

When constructing a heald-light driving device which is abrasion resistant and practically incurs no maintenance cost according to the present invention, at least the guide roller is preferably made of plastic aluminum with hardened steel or abrasion resistant coating.

Furthermore, the guide rollers can be arranged inside between the plate cam and the heald slide frame, and each guide roller can be arranged on the front drive surface or driven surface on the heald slide frame. In addition, the axis of the guide roller is inclined and extends particularly radially with respect to the plate cam, so that the tangential force and the radial force can be transmitted more efficiently.

Therefore, as can be seen above, the present invention can provide a circular loom driving device of a circular loom having a very quiet, robust, simple and precise driving concept.
