Description

The invention relates to a method for the machine production of a woven product from individual threads, wherein the threads are withdrawn from bobbins, the bobbin in curved track sections and the track sections are connected via intersection points to each other mutually crossing orbits. In addition, the invention relates to a device for the machine production of a lichen product from individual threads which are mounted on bobbins, wherein the bobbin held in curved track sections and the curved track sections are connected to each other via intersection points to mutually crossing orbits.

In the braiding technique, the production of branches is known. Such branches are used in many fields of technology, in particular in the construction industry, the aircraft industry, the automotive industry and sports equipment. Since the production of these branches by means of continuous fibers is expensive, the production takes place mainly in laborious manual work by several fabric blanks are combined into forms and connected to each other with Binderfließ and resin. From the bicycle industry, it is known to combine fabric blanks of fiber composite pipes by means of metallic branch pieces together. The assembly of the individual fabric blanks is done regularly in costly manual labor.

In order to produce branches without fiber interruption, braiding machines are known, which allow a braiding of wire harnesses. When this case applied braiding technique, the individual branches of the cable harness are braided by appropriate forward and backward movement of the entire harness sequentially. The secondary strands are each braided twice. This principle of braided branching is also used for the production of branches in fiber composite technology. Here, a rigid core is moved by means of a robot in the thread take-off of the braiding machine. However, this manufacturing principle is less suitable to produce branched hollow braids, since the subsequent withdrawal of the cores from their braids can only be done manually and therefore is expensive and expensive. In addition, it is unsuitable for making branches with branching angles significantly less than 90 °. Furthermore, the known manufacturing principle does not allow optimal formation of the thread profile in the branching areas.

The invention is therefore based on the object to show a method and an apparatus of the type mentioned, which allow efficient production of lichen products with any number of branches.

This object is achieved by a method with the features of claim 1 and by a device having the features of claim 5. Advantageous developments of the invention are specified in the respective dependent on these claims subclaims.

The method according to the invention is characterized in that the web sections interconnected to orbits are interconnected to form a number of first midsole circles, that the bobbins are moved circumferentially on each first mantle circle so that at least two web sections each having at least one guide direction are provided. an opposing guide direction having track section to at least two Switching tracks are interconnected, after the bobbin carriers were moved through each first Mantelflechtkreis circumferentially, that the bobbin are moved over the interconnected to switching paths track sections in a switching position, that interconnected to switch tracks track sections are interconnected to a number of second Mantelflechtkreise after the bobbin were moved into the switch position, and that the bobbin on each second Mantelflechtkreis be moved circumferentially.

Each Mantelflechtkreis has two mutually crossing orbits with opposite directions of leadership, so that in the one orbit run coil carrier run counter to the guided in the other orbit coil carriers. By continuing in this switching position circulation of the bobbin on each first Mantelflechtkreis a number of first Mantelflechtkreise corresponding number of hollow braid is generated until the switching paths are interconnected from the opposing guide directions having track sections. Each switching path also has two mutually crossing orbits with opposing guide directions, so that in the one switching path guided coil carrier run counter to the guided in the other switching path coil carriers. However, unlike the Mantelflechtkreise the switching paths are not suitable to move circumferentially on the coil support located in them, as they would collide with each other already in the passage of their first four track sections. The switching paths are used exclusively to move the coil carrier into its switching position. For this purpose, all bobbin carriers are moved into an adjacent track section without collision, preferably into an immediately adjacent track section. Only this switching position allows the interconnection of the track sections to a number of second Mantelflechtkreise in which the bobbin carriers can then be exposed to collision-free continuous orbital movements. Due to the continuous circulation of the bobbins on every second Mantelflechtkreis is then, up to a re-interconnecting the switching paths, a number of the second Mantelflechtkreise corresponding number of hollow braids produced. Depending on the number of first Mantelflechtkreise and the number of second Mantelflechtkreise the inventive method is suitable for producing willow products in which any number of hollow braids are intertwined over any number of branches. Manually performed operations and the use of binder flow and resin can be advantageously dispensed with.

According to a first development of the method according to the invention, the switching paths are each interconnected from track sections, wherein the track sections in the switching state of a larger number of Mantelflechtkreisen belong to orbits of different Mantelflechtkreise. In particular, the switching paths are each connected together from two track sections, these two track sections in the switching state of a larger number of Mantelflechtkreisen belong to at least two Mantelflechtkreisen. In this way, a hollow braid is made with a simple branch. In more than two mantle braided circles, hollow braids can be manufactured with nodes in which more than three strands of a hollow braid converge.

According to a next development of the invention, the switching paths are interconnected in each case from track sections which belong to one and the same Mantelflechtkreises orbits in the switching state of a larger number of Mantelflechtkreisen orbits. In particular, each Mantelflechtkreis two orbits. Whether the switching paths are interconnected in each case from web sections which belong in the switching state of a larger number of Mantelflechtkreisen each another Mantelflechtkreis or two orbits one and the same Mantelflechtkreises can be advantageously made dependent on control-technical circumstances and requirements.

Since the necessary for generating the branches control engineering processes depending on the trained and trainees Mantelflechtkreise and depending on the composition of the switching paths are different, the bobbins are moved to a starting position before interconnecting the switching paths, wherein the guide direction in the interconnected to switching paths track sections in Depending on the starting position of the bobbins maintained or vice versa. Particularly preferably, the web sections are interconnected to such switching paths and the bobbins in the switching paths occupied with such start positions that the guide direction is maintained in the interconnected to the switching paths track sections with respect to the guiding direction of the orbits. In this way, the switching processes to be carried out in accordance with the invention can advantageously be carried out quickly and with little load in synchronism of the coil carriers.

The inventive device for machining a lichen product is characterized in that the orbits at least two Mantelflechtkreise are formed, that the two orbits of one of the Mantelflechtkreise are each connected via a first crossing with one of the orbits of each other Mantelflechtkreises that together in one Mantelflechtkreis arranged orbits are each connected to each other via a second crossover switch, and that each first intersection is connected to each second crossover over only a single track section.

The first intersection points serve to interconnect each of the track sections having the same guide direction, in each case with at least one track section having an opposite guide direction, and interconnect the tracks to a number of first plain-braided circles or a number of second plain-brained circles. The second crossing points, however, serve only to interconnect the orbits to a number of first Mantelflechtkreise or another number of second Mantelflechtkreise. The fact that each first intersection switch is connected to each second intersection switch over only a single track section, regardless of the number of guided in the orbits coil carrier can be ensured that all running from the bobbin threads both in the number of first Mantelflechtkreise and in the number second Mantelflechtkreise are involved in the braiding process.

According to a first development of the device according to the invention more than two Mantelflechtkreise are formed with the orbits, wherein the Mantelflechtkreise are arranged in a ring shape, and the two orbits of each Mantelflechtkreises are each connected via two first crossing points with the orbits of each in the ring formation adjacent arranged Mantelflechtkreise , In this way, each Mantelflechtkreis is suspended over a total of two pairs of first intersection points in the ring formation forming composite of Mantelflechtkreisen. The first intersection points serve both to interconnect the switching paths and to connect the track sections connected to one another to form a number of first or second mantle-type magnetic circuits.

According to a next development of the invention, each arranged in a Mantelflechtkreis orbits are connected to each other via a third intersection, each third intersection junction is connected to each second crossover of the same Mantelflechtkreises only a single track section. With the third crossing points, it is possible to interconnect Mantelflechtkreise arranged in a ring formation to a single Mantelflechtkreis such that its orbits enclose the center of the ring formation in each case in a symmetrical manner. The fact that every third intersection is connected to every other crossover of the same Mantelflechtkreises only a single track section, regardless of the number of guided in the orbits coil carrier can be ensured that all of the bobbins ongoing threads are involved both in the number of first Mantelflechtkreise and in the number of second Mantelflechtkreise the braiding process.

According to a particularly advantageous embodiment of the invention, the curved track sections are associated with the coil carriers interacting impellers, all impellers are arranged in the grid cells of a Cartesian grid gapless. Such a compact arrangement of the impellers has in addition to an optimal utilization of the space available for the device according to the invention the advantage of an optimal thread guide. This is of crucial importance for the production of particularly dense and dimensionally stable lichen products.
