Description

DETAILED DESCRIPTION OF THE INVENTION The knitting kettle rotates, each knitting kettle having rollers arranged in pairs on its top and bottom edges, said rollers being connected to the upper knitting kettle lace or knitting kettle. supported on a corresponding sliding surface on the lower shirttle race and also.

The present invention relates to a circular loom in which a suppression roller rotated by a plate cam of the loom is provided on each weaving shirttle.

The previously known circular looms have inner and outer partial belts, which are arranged circularly in rows around the circular reed of the loom, each partial belt being all distributed around the loom. It has a number of inner and outer belts to guide a portion of the warp threads of one system, and the warp threads are moved in opposite directions by the main axis to form weaving strips or running strips. It is designed to be able to give vertical cross IL motion. A weaving shuttle rotating inside a circular reed conveys the unrolled weft yarn from each package.
it: Vi, Ru.

In an effort to increase the productivity of such looms, the rotation of the weaving shirttle;

Attempts are being made to increase the storage capacity of the weft yarns.

However, the guidance of the weaving shirttle on the conventional type of circular reed is limited by the added burden and the Tonomi/Buno's Soka.

These limitations are clearly manifested in significant wear of the rollers and an increased risk of damage to the warp threads rolling over the upper and lower rolls. Therefore, by avoiding the deficiencies of conventional arrangements, , the output capacity of the loom was increased by 3'' less than the 11'' length of the loom, permitting the utilization of a larger f,X warp yarn stock. It is one object of the present invention to obtain a 1* type circular loom.

This objective is according to one invention. The rotation axes of the upper and lower rollers of the six pairs of rollers on the weaving shirttle border a conical surface, the apex of which is in the region of the axis of rotation or the axis of rotation perpendicular to the axis of rotation of the fabric, in which case said roller is configured in the form of a truncated cone, the apex of which coincides with the axis of rotation of the apex of said cone; Also, the fVt of the upper or lower shirttle race! If! This is achieved by ensuring that the + surfaces form opposing surfaces that are equally inclined to the surface of the roller.

These measures allow an optimal rolling movement of the rollers on the sliding surface of the shuttle race even when the centrifugal force is increased, in this case.

Not only is wear on the surface significantly reduced;
When running at low speeds or at rest, escape of the weaving shirttle from the circular path of the reed is also prevented.

These aforementioned advantages can be further increased because the surface of the roller extends inside the radial square dimension of the sliding surface of the shuttle race.

Furthermore, in order to create the best conditions for the yarn to roll between the rollers for driving the shirttle, at least the upper part of the shirttle forming the pressure roller when the weaving roller is completely open is It is advantageous for the line of contact between the roller and the counter-pressing roller on the plate cam of the loom to run in alignment with or parallel to the warp threads of the lower track.

Preferably, the arrangement according to the invention is such that the warp threads of the upper string and the warp threads of the lower string are connected to the upper or lower lace when the running string is completely open. Preferably, it extends in the plane of the upper opposing surface and has an angle of inclination that is the same as that of the fabric removal device.

In this way, these means can be applied to the ideal f, f thread of the upper and lower threads of the warp.1. ), but these warp threads are in this case neither crushed nor deflected from the ideal direction of their path towards the fabric removal device, which means that the thread l, IJ Reduces losses quite significantly.

In addition, in order to be able to compensate for possible slippage between the rollers connected to the drive of the handle, the pressing counter-roller above the shuttlecock has a truncated-conical shape and a larger diameter. has an R of 3
It is advantageous to have the surface of the pressure roller on the plate cam come into engagement contact when the surface rotates 5%.

Another development according to the invention is that a circular reed can also be provided with vertical bars arranged & spaced from each other in the circumferential direction of the reed between the shirttle guide rods, said vertical bars being above the inner side of the reed. 1 to 1 in the radial direction at the front of the shaft guide frame of
It absorbs the centrifugal force on the weaving shirttle that rotates once,
The object is to form a circular path for the weaving shirttle. In this case, if at least three vertical rods each support the weaving shirttle for one revolution, and if INσ is freely rotatably supported by the lower fj or lower shirttle lace, It would be advantageous if, furthermore, each weaving shirttle had a moving runner intended for interaction with the 1α rod.

Alternatively, an advantageous arrangement can be made in order to transfer the increasing force directly onto the frame of the loom without the shaft guide rod breaking contact and generating a large amount of frictional heat. (1E consists of the fact that the weaving knottle is supported on the shirttle guide rod by means of a rotating "1-ra" which runs parallel to the shirttle lace, on top of the shirttle guide cassette.

Furthermore, according to the present invention, the one-turn roller is provided with a shaft guide in order to ensure that when the Nyatle is rotating, there is no kernel that falls into the space between the Nyatle guide persimmons and causes "knocking". The rods are bent convexly outward in the direction of the rotating circumference of the circular reed, or the shirttle guide rods are arranged at a different inclination with respect to the vertical frame, or the shirttle guide rods are It is intended to be arranged in the shape of an arrow in the circumferential direction of rotation of the shaft, in which case if the shuttle guide rods are flattened over their entire length on a circular path. It is advantageous if l, 1' is equal to 1'.

Embodiments of the present invention are shown in the attached drawings No. 1 to 1 below.
Details based on Figure 9 K ill? , reveal.

The circular loom shown in FIG. 1 is mounted in the conventional manner on a loom stand frame/frame, and also includes a circular frame carrier 2 supporting a circular reed 3 and a starting/stopping means q for the loom. and another frame part S for supporting the belt 6. These belts 6 are arranged in a circular manner around the main axis g of the loom in a known manner.

Furthermore, a support 7 for a fabric extraction device, which is only indicated in the figure by a fabric removal roller lO, is supported on the loom frame l. Textile expander/gu as well.

Displaced within the range of drained oil @IO. Furthermore, it is also possible to see in the circular loom shown: 11, the supply roller /S for the upper warp on the right hand side and the supply roller /6 for the upper warp on the right hand side 11111. These warp threads 7 are divided into sheets of thread of 1.2 systems, the course of which is merely shown, and are drawn out by a group of warp thread spools in the same manner as in January. The spools of threads 7 are not shown in Figure 1, nor are they shown in detail in Figure 1.For the formation of the weaving strips, one of these sheets of thread 7 must be weaved through an exchange of so-called shedding movements. From the level of the plane, it is lifted, but the seams of the other thread 7 are guided downwards.

As a result, a three-way path 71 of the warp yarn and a downward path of the warp yarn are created. In this so-called running wheel or weaving wheel, a shuttlecock 3θ (Fig. For circular motion,
The yarn picked up from the weft bobbin AO is transferred onto the edge of the cylindrical fabric /3, 5 thereby allowing the yarn of this shirttle 3Q to be woven into the fabric. The cylindrical fabric was removed.

It is made of flat cylindrical fabric and laid out in a row.

In order to produce the above-mentioned rotational change, a number of belts 6 are arranged in a circle around the main axis g of the loom near the outer surface of the circular reed 3. As can be seen in FIG. 1, each belt 6 consists of one partial belt, for example 5 formed by the constituent parts of the band, 2g and 2j. For example, an endless band
For this purpose, it is guided on guide rollers 2.2 and 23, respectively, which are rotatably supported on the upper and lower parts of the frame S.

It is known that one pressure roller 63 rotates with the rotating shuttlecock Jθ due to the drive according to FIG. It is intended to lie on roller 6.2. In order that the shirt torque 30 can be guided without tilting between the upper and lower shirt torque slides/and sliding surfaces 3 and 11 of the groove, it is also possible to avoid any vibrations of the roller drive mechanism. In order to prevent this, either the roller 61 arranged by the pressing counter-roller 6.2 on the shuttlecock 3θ or, as in a variant thereof, the pressing counter-roller 6a itself,
It is supported flexibly by a spring 67. - For this purpose, the pressure counter-roller 6.2 is placed on the free end of the lever arm 6, which is pivoted on the shirttle 30, and the shirttle 30 is, in FIG. It is biased 9 counterclockwise by the spring 67 having a shape of .

The pressure roller Otsu 3 is located approximately at L above the plate cam 33 of the loom.
Glyph bracket, ',? In this case, the axis 4J' of the pressing roller 63 extends substantially parallel to the extension of the warp thread 71 in the lower path in the open position. The surface of the pressure roller 63 is
The 77144' surface of the large 1jlY= roller above the 6:1 jII+pressure counter roller 6:1 is brought into engagement contact with the surface of the 77144' roller, making it suitable for transferring the two. In this case, the circumferential velocity is greater than the circumferential velocity on Nyatsutle 30, 'jli
U.

The shoulder 6y of the driven roller 6.2 is 9!
As a result, slippage during cl movement is reduced to sleeve IF.

The pioneer brake roller AA is mounted on the bracket 69 in the same way as the pressure roller t, 3 is removed, and similarly, the surface of said brake roller 4 is , the roller debris 41IO) on the suppression rollers A, 2 is suitable for engaging and contacting the surface of the brake roller 66 (IO) fJ and rolling thereon. , 4111 of Shirttle 30
It lies at a slightly lower level than the suppression roller A3 above the pressure counter roller 4U. This brake roller 6
6 is due to the inertia of the shuttlecock 30.

Pressure roller i...? independent of the drive caused by, and prevents it from continuing on that path.

By arranging and driving the 7Ps and other rollers on the shirt handle 3o, it is not only possible to achieve the best condition, but also the best way to pull up the warp threads in the upper and lower strings. The state of 1. is also generated. i1. Despite a substantially higher rotational speed and a larger or heavier weft yarn wrapping 6o, substantially less yarn breakage can be expected.

Due to the increased rotational speed, the relatively heavier shirttle 3o now generates a substantially greater centrifugal force on the shuttlecock guide 3' and thus the shuttlecock 3o.
The trap supported simply by sliding launch means on the guide rod 3' is no longer sufficient.

According to the invention, it is therefore provided that each shirttle 3.0 is provided with a vertically rotating roller 7o parallel to the shirttle guide rod 31, these rollers 7θ preferably being As shown in the figure, it is preferable to place it near the end of the somewhat long shirt tortle 30, and
Above the sea A' sotol 30, a roller 70 is supported in a manner not shown in further detail here.

Each rotating roller 7o is rotated 116 while the weaving shirttle 30 is being rotated, in order to ensure that the rotating roller 70 does not fall between the yarn yarn guide bales 3', thereby causing "slapping".

It must be in supporting contact with at least seven shuttle guide rods 31. For this purpose.

More specifically, as shown in FIG.
Each rotating roller 70 is bent in such a way that it always lies by part of its surface against one of the seven kettle guide extensions 3'.

In order to achieve the best transfer situation, Nyattle guide rod 3
1 is also flattened in order to produce the largest possible surface of the circular path, as particularly shown in FIG.

Similar results are obtained if the shirttle lace 31 is shown in more detail in FIG.

This can be achieved if the arrangement is inclined. Also.

As shown in FIG. 7, it is also "J fiF" that the shuttlecock guide rod 31 is arranged in the shape of an arrow.

In this relationship, in order to satisfy the above-mentioned requirement, the convex bend or slope of the shuttle guide rod 3' or the shape of an arrow should be set to a small f, +', (+'- also, -2 adjacent It is important that the spacing between the guide rods be the same as the surface, or preferably larger.

From the foregoing, one would expect an increase in the performance of the loom through the faster rotation of the weaving shuttle and the use of larger warp wrappings, with increased thread wear and more risk of thread breakage. A guiding arrangement and a driving arrangement of the weaving shirt truss is produced which makes it possible to do so without the need for a weaving shirt.
