Description

circular loom

The present invention relates to a circular loom having the features of the preamble of claim 1 .

Generally, circular looms for the production of fabrics are known from the prior art, which have circular reeds arranged coaxially with the main shaft of the circular loom. The main shaft forms the main axis of the circular loom. Regarding the circular reed, a segmented track guide element is arranged, which is adapted to feed a plurality of segmented tracks to the circular loom. The weaving shed forming device groups the segmented scars fed into it into two segmented scar bundles and imparts an alternating motion to these relative to each other, thereby opening and closing the braiding shed between the two segmented scar bundles. The waving shuttle circulates on the track of the open weaving shed, introducing the weft tape into the weaving shed to form the fabric. Remove the fabric through the braided loop. For modern circular looms, there are usually several weaving shuttles circulating simultaneously in the corresponding weaving sheds of the circular reeds. On the main shaft of the circular loom, a control curve carriage is formed, the control curve carriage having at least one undulating control curve circulating around the control curve carriage, and around the control curve carriage there is provided a control rod, which engages with the control curve carriage At least one end of the control curve. As a result of the rotation of the main shaft and the rotation of the control curve carriage, the ends of the control rods are given a deflection movement by the control rods diametrically opposite to the weaving shed-forming means, whereby these are given alternating movements and A wavy weave shed is formed in the loop direction. The cross-section of the wave-like weaving shed parallel to the main axis in the circulation direction in this way corresponds substantially to the cross-section of the convex lens. If the braiding shed-forming device has lugs held by the half-shafts for guiding the segment marks, usually two levers are provided per braiding shed-forming device. If the knitting shed-forming device has a belt with lugs that is offset around two deflection rollers for guiding the warp belt, usually only one lever is provided per knitting shed-forming device. For example, a circular weaving machine with a weaving shed-forming device with half shafts is known from document IN 159848 A1. For example, from document EP 2 829 645 A1 is known a circular loom with a knitting shed-forming device with a belt deflected towards about two deflection rollers.

However, in the operation of the known circular looms, it has proven disadvantageous that the circular looms are often limited by maintenance intervals due to the multiple control levers, and due to the friction in the machine regulated by the multiple moving parts, the need for lots of energy. It has proven to be disadvantageous that the known circular looms are very noisy and very space-consuming due to the number of control rods arranged around the control curve carriage. For this reason, first efforts have been made to minimize the number of levers. This is achieved by combining into groups a plurality of adjacently arranged weaving shed-forming devices, these assemblies being articulated simultaneously by one or two levers depending on the configuration. In this way, however, the number of levers has been reduced, but due to the simultaneous articulation of several weaving shed-forming devices, a stepped weaving shed is formed, which has the disadvantage of being shortened in the end region due to the stepped shape, and When viewed along the entire length, it will provide less space for the weaving shuttle due to the less space that can be used. Furthermore, due to the stepped shape, the dead space between two consecutive weaving sheds will increase, whereby a smaller number of weaving shuttles can simultaneously circulate in the circular reed with such a circular loom. However, the lower number of weaving sheds leads to a decrease in the productivity of the circular loom and thus reduces the output of the circular loom.

The task of the present invention is to provide a circular loom which overcomes the disadvantages of the prior art and has high production safety and high productivity.

According to the invention, the proposed task is solved by the features of the characterizing part of claim 1 . Preferred embodiments of the present invention are the subject of the appended claims.

The weaving shed forming device of the circular loom of the present invention has a plurality of pivoting elements and a segmented notch lifter that guides the segmented notch, wherein each pivotal element is connected to at least two, preferably a plurality of segmented notch lifts device. When the control curve carriage rotates, the control curve performs a pivoting movement directly or indirectly about a pivot axis, which is arranged substantially radially on the main axis, and as for the radial lifting movement of each pivoting element . The pivoting element imparts, due to the pivoting movement and the lifting movement, the segmented mark lifting means, thereby opening and closing the weaving shed, according to the gradient and thus at least on the course of the control curve. Advantageously, the pivot axis extends centrally through the pivot element.

In this connection, it is indirectly or directly intended that the pivoting element may be directly coupled to the at least one control curve, or the pivoting element may be coupled to the at least one control curve by a connecting element such as a lever, rod or gear .

In this connection, substantially radially to the main shaft means that the pivot axis of the pivot element can also be arranged slightly inclined towards the axis arranged radially to the main shaft.

As a result, the circular loom according to the invention comprises a weaving shed forming device which has a very simple arrangement and forms a weaving shed with a lens-shaped cross section. In this way, the circular loom of the present invention is not only very efficient, but also low maintenance and economical to operate. Due to the lenticular cross-section of the weaving shed / weaving shed, it is possible to maximize the number of weaving shuttles circulating simultaneously within the circular reed, or in the case of the same number of weaving shuttles, between the weaving shuttle and the segment marks The distance of can be increased at the braiding shed/the end of the braiding shed, which will reduce the risk of the braiding shuttle colliding with the segment marks and will prevent breakage of the segment marks thus accommodated. In this way, the circular loom according to the present invention can be operated at a higher speed than conventional circular looms. Furthermore, due to the advantage of the lens-shaped weaving shed, the gradient of the control curve at the end of the weaving shed can be smaller than that of the stepped weaving shed, resulting in a reduced acceleration when the moving parts are deflected, which can be further improved by this The productivity of the circular loom according to the invention, and the protection of the moving parts.

Due to the pivoting movement and the lifting movement of the pivoting element, the course of the at least one control curve substantially corresponds in the circulation direction to the course of the weaving shed. Thus, by alternating at least one control curve, the course of the weaving shed can be adjusted quite easily.

At least one control curve is preferably formed by notches, grooves or protruding rods.

Furthermore, a plurality of weaving shed-forming devices 5 are arranged around the circular spring 2, which divide the segmented scars 4a and 4b fed into it into a first segmented scar bundle 10a and a second segmented scar bundle 10b , and give the two segmented scar beams 10a and 10b an alternating movement relative to each other - by means of control curves 6 and 7 . In this way, the weaving shed 11 is opened and closed between the two segmented scar bundles 10a and 10b. In the open weaving shed 11, a weaving shuttle, not shown, circulates in the circulation direction, and while circulating in the circular spring 2, the weft tape is introduced into the weaving shed 11, thereby forming a fabric. Advantageously, a plurality of weaving shuttles circulate simultaneously in the respectively open weaving sheds 11 in the circular loom 1 . The circulation direction extends along the circular reed 2 .

The knitting shed-forming device 5 has a first pivot element 12 guided spaced apart from the first guide 34 and parallel to the main axis, and a second pivot element 13 which is guided by The guide is spaced apart from the first guide 35 and parallel to the main axis. The weaving shed-forming device 5 also has a segmented mark lifter, its segmented marks 4a and 4b. The segmented mark lifter is formed by half shafts 14 and 15 and lugs 16 and 17, wherein one lug is rigidly connected to the first half shaft 14 and one lug 17 is rigidly connected to the second, respectively Half shaft 15.
