Description

Pattern warping machine (1) Field of invention

The present invention relates to a pattern warping machine having a warping roller that can be rotated about an axis by a take-up driving device, and a plurality of wire guides, each of which can be driven by a drive The device moves parallel to the axis between a rest position and a take-up area, the rest positions being arranged along a line.

Background of the invention

A pattern warper is used to produce a pattern warp yarn, also known as a "short warp yarn." For this purpose, the thread is wound endlessly around the circumference of the warping drum. In order to achieve a warp of a limited length, the threads are then cut at defined points.

A known type of warping machine uses a warping drum that is paused during the winding line. The wire is guided by rotating the wire guide back and forth on the circumference of the warping drum. At this time, the wire is pulled off from the bobbin disposed in the rotating creel that rotates together with the wire guide. Although this type of procedure has been proven in principle, it has a limitation because only a limited number of spools can be carried in the rotating creel. Thus, the number of lines that can be warped at the same time is limited.

Therefore, an attempt has been made to construct a pattern warper in such a manner that the warping drum rotates during the winding and the thread guide remains stationary with respect to the circumferential direction of the warping drum. At this time, the wire guide can be moved parallel to the axis of the warping drum so that it can be positioned in front of the end side of the warping drum in the axial direction or in the axial length of the warping drum. In the first case, the wire is removed from the pattern forming operation and taken up, for example, on a center cable. In the latter case, the thread is taken up on the circumference of the warping drum. In many cases, the conveyor belt or other conveying surface is disposed on the circumference of the warping drum, and the conveyor belt or other conveying surface is moved away from the end side of the shaft of the parallel warping drum.

In theory, this type of pattern warper can simultaneously wind up a substantially larger number of lines. Since a conventional fixed creel can be used, it can accommodate substantially more spools. However, the number of wires that can be used at the same time is limited by the fact that each wire guide must have a drive. This drive requires a certain amount of installation space, with the result that the number of wires that can be crimped or warped at the same time is also limited. This limitation also limits the productivity of the pattern warper.

Summary of invention

The present invention is based on the object of providing a high-productivity pattern warper.

In the pattern warper of the type mentioned in the preamble, this is achieved by the fact that the drive arrangement is distributed over both sides of a plane formed by the projection of the lines parallel to the axis.

The drives are thus divided into two groups, and the two groups are assigned to two locations. Therefore there is twice as much available space as to accommodate more drives in a corresponding manner. However, for this purpose, specific changes on the wire guide are required. A set of drive means acts radially from the outside of the shaft of the wire guide about the warping drum; at the same time, the other drive means acts radially from the inside of the wire guide. Thus, the operating link between the drive and the wire guide must be designed accordingly.

The drive means disposed on one side of the plane is preferably distributed over a plurality of regions at different distances from the rest position parallel to the axis. The drive devices can therefore not only be divided into two groups, but can also be assigned to a group of different regions, so that an additional number of installation spaces are obtained; therefore, a relatively more drive for the wire guide can be Accommodated in it.

It is advantageous at this time that the drive devices arranged in different regions are at different distances from the plane. An embodiment of this type is advantageous, particularly when the drive has a magnet, which is the case in most electric drives. Then, the driving devices adjacent to each other can be arranged at intervals sufficiently large from each other, and it is possible to prevent the driving devices from being affected by the mutual influence of the magnets of the other driving devices. This spacing is therefore greater than an influence length. This effect length is usually predefined by the manufacturer of the drive unit. Due to the multiple distribution of the drive in three spatial directions, a large number of drives can be used, however these drives do not split or affect each other.

Preferably, the line has an arched course direction. Therefore, it is not necessary to use a straight line in order to arrange the wire guide in the rest position. Instead, the wire guides can be configured as desired. In the case of the direction of the arched route of the line, the plane has a corresponding curvature.

Preferably, the direction of the arched path is adapted to the warping drum. This ensures that, for example, wherever the line is guided, all of the wire guides are equally spaced from the circumference of the warping drum.

Each of the driving devices is preferably configured as a linear driving device having a stator and a movable member, the movable member being coupled to the wire guide by an extending portion. This leads to further design options. Due to the use of an extension, the selection system is relatively free with respect to the configuration of the drive associated with the position at which the line is ultimately guided. This is usually a wire shuttle. The extension can be of a relatively light weight configuration, such as a tube made of carbon fiber reinforced plastic.

The movable member is preferably connected to the wire guide at two positions spaced apart from each other in the moving direction of the wire guide. This ensures that the wire guide mainly loads a driving force acting in its longitudinal direction, specifically, even if the longitudinal length of the wire guide does not overlap with the moving axis of the movable member, but is substantially parallel thereto. Thus, it is possible to orient all of the guides along the lines in their rest positions and to position the drives at different heights, that is, at different distances from the plane.

The movable element preferably acts on a triangular rod that is coupled to the wire guide. For example, when the bottom of the triangular rod is formed by the wire guide, the movable member can act on the top end of the triangular rod. This is a relatively simple embodiment in order to understand the desired drive concept.

At this point it is preferred that at least some of the triangular bars have a reinforcing strut. This is advantageous, especially in the case where the rods connect the wire guide to a drive that is located at the furthest distance from the plane. The reinforcing struts also slightly stiffen the horn so that the movement of the drive can be transmitted to the wire guide with high accuracy.

Each of the wire guides preferably has bearing points on both sides of the rod. This prevents the drives from passing a tilting moment into the wire guide, even if a rod or the like is used. More specifically, the wire guide is mounted in such a manner that the wire guide performs a pure linear movement parallel to the axis of the warping drum.

Preferably, the driving devices are combined with each of the plurality of modules, and one module has a number of driving devices that are divisible by four. In this case, each set of four driving devices can be distributed in such a manner that two driving devices are disposed on one side of the plane, and two driving devices are disposed on the other side of the plane. . The two drive devices on each side of the plane are then placed at different distances from the plane and at different distances from the rest position. All of the drives of a group of four modules are therefore located at a sufficient distance from each other such that they do not affect or interfere with each other.

Simple illustration

In the following, the invention will be described using a preferred embodiment in combination with the drawings, in which: Figure 1 shows a schematic, schematic illustration of a pattern warper; Figure 2 shows a module with a plurality of conductors a three-dimensional illustration; FIG. 3 shows a plan view of the module; FIG. 4 shows a side view of the module; and FIG. 5 shows a three-dimensional basic illustration for explaining the configuration of four driving devices; and FIG. A front view according to Fig. 5 is shown.

Detailed description of the preferred embodiment

A pattern warper 1 has a warping drum 2 connected to a winding drive unit 3 as schematically illustrated. The take-up driving device 3 is capable of rotating the warping drum 2 in the direction of the arrow 4 during the winding.

Most of the spools are placed in a creel (not shown). In the present exemplary embodiment, up to 128 reels can be disposed in the creel.

A wire is pulled from each spool and guided through the wire loop 5 of a wire guide 6. All of the wire guides 6 together form a line transfer unit 7. It can be seen that the wire guides 6 are arranged in four groups, each group 32 having a wire guide 6.

The wire guides 6 can be moved in such a manner that the wire eyelets 5 are guided in the axial direction above the warping roller, so that the wire guided through the wire eyelet is taken up to the warping. On the circumference of the drum. Then, the lines are then placed on the conveyor belt 8 forming the conveying surface, and the conveying surface is moved away from the end side of the shaft parallel to the warping drum 2, and the line shifting unit 7 is disposed on the end side. If the wire is not placed on the circumference of the warping drum 2, the corresponding wire shuttle 5 will be moved forward of the end side of the warping drum 2. The cords used to create the pattern warp yarns are not required to be taken up onto a center cable (not shown). For all wire shuttles 5, this is shown in Figure 1. The wire guides 6 are thus in a rest position. These wire bobbins 5 are all arranged along one line. In this case, this line is an arched configuration. The wires are guided in such a way that all the wire loops 5 are actually located at the same distance from the axis of the warping drum 2 and are therefore substantially at the same distance from the circumference of the warping drum 2. If the warping drum 2 is rotated and the wire guides 6 have been moved in such a way that the wire guides the wire over the circumference of the warping drum 2, then the same take-up state will be produced for all the wires.

In order to form a so-called division or particle size distribution, a dividing rod 9 arranged between the conveyor belts 8 is provided. Each of the dividing rods 9 has a tip end 10 facing the line shifting unit 7 at its end, which tip 10 is substantially radially directed outward. The tip end 10 is fixedly disposed above the branching rod 9.

If a line is placed radially outside on a dividing rod 9, the line is finally placed over the dividing rod 9 facing and away from the side of the tip end 10 of the line transfer unit 7, corresponding The wire shuttle 5 is moved in the axial direction in this manner. However, if the wire is placed radially below the dividing rod 9, the wire guide 6 makes a movement toward the end side at this moment, and the corresponding dividing rod 9 passes through the wire shuttle 5 so that the wire does not It is held by the tip 10. After passing through the dividing rod, the wire shuttle 5 is moved back to its original position again, so that the winding operation can continue.

In order to detect the position of the dividing rod 9 in relation to the warping drum 2, a sensor arrangement 11 is provided. The sensor arrangement 11 is disposed on the machine frame 12 in a stationary manner and detects the dividing rod 9 located on the circumference of the warping drum 2 each time the dividing rod runs past the sensor configuration 11. position.

If the associated dispensing work of the warping drum 2 and the dividing rod 9 is known, it is possible to control the movement of the thread guide 6 in a relatively simple manner so that the line can be placed above the dividing rod 9 or Below.

Further, during each rotation of the warping drum, the wire guides 6 are moved by a slight amount away from the end side of the warping drum 2 to the axial inner side of the warping drum 2, so that the warping drum 2 is circumferentially A roll is formed having a conical end side on its circumference. This is intended to prevent the wire from falling off at the end side, which may make the subsequent warp yarn unwinding difficult or even impossible.

Figure 2 shows a module 13 having 32 wire guides 6 and a corresponding number of wire shuttles 5.

Each wire guide 6 has a drive of the type of linear drive 14. The wire guides 6 disposed on each other form a curved plane. This plane can also be produced by a line formed by the wire eyelets 5 displaced parallel to the axis of the warping drum 2. In other words, the plane is formed by the projection of a line parallel to the axis of the warping drum 2.

A first mounting wall 15 is radially disposed on the outer side of the plane with respect to the axis of the warping drum 2, and a second mounting wall 16 is radially disposed on the plane with respect to the axis of the warping drum 2. Inside. Thus, it is possible to install a total of 16 linear drives 14 on each of the mounting walls 15, 16. The linear drives 14 mounted on the first mounting wall 15 form a first set. The linear drives mounted on the second mounting wall 16 form a second set.

An internal space 17 is formed between the two mounting walls 15, 16. Within each set, one half of the linear drives are placed in the interior space 17 and the other half is placed outside the interior space 17. Thus, only the linear drives 14 fixed to the second mounting wall 16 and outside the interior space 17 can be seen in their entirety. These linear drives 14 are vertically disposed on each other and form a stack.

A second stack of linear actuators 18 is mounted to the second mounting wall 16 and is located within the interior space 17. It can be seen that the second linear drive 18 is at a relatively small distance from the rest position.

The linear drives 14 are at a greater distance from the plane than the linear drives 18. Moreover, the linear drives 14 are at a greater distance from the stationary position than the linear drives 18.

The mirror reverse configuration of the linear drives 19, 20 occurs on the first mounting wall 15. The linear drives 19 are disposed on the first mounting wall 15 and outside the interior space 17. The linear driving devices 20 are disposed on the first mounting wall 15 and inside the internal space 17. Thus, the linear drives 19 are at a greater distance from the plane than the linear drives 20 and are also at a greater distance from the rest position.

All linear drives can thus be configured in such a way that their equidistant distances are sufficiently spaced apart from one another such that they do not interfere with one another or otherwise influence each other.

As can be seen, in particular in the third diagram of the linear drive unit 20, the linear drive unit 20 has a stator 21 and a movable element 22. A coil configuration is placed in the stator in a manner known in the art of linear drives, and a moving field can be generated in the coil configuration. In order to move the movable element 22, the movable element 22, which may also be referred to as a "rotor", for example, has a permanent magnet that can then be driven by a moving field.

The movable element 22 is attached to an extension 23, such as a tube constructed of carbon fiber reinforced plastic. This type of extension 23 can thus be organized with a relatively low mass.

The extension 23 connects the movable element 22 to a rod 24 that is substantially triangular in shape. More precisely, the extension 23 acts on the top end 25 of the rod 24. The rod 24 cooperates with the two base points 26, 27 on the thread guide 6. The linear drive unit 20 is thus connected to the wire guide 6 at two positions spaced apart from each other in the moving direction of the wire guide 6. As a result, it can be attained that the driving force generated by the linear driving device 20 is substantially guided in the moving direction of the wire guide 6.

The wire guide 6 is mounted on both sides of the rod 24, specifically the first guide 28 between the rod 24 and the linear drive 20, and between the rod 24 and the wire shuttle The second guide 29 between the eyes 5.

Each wire shuttle 5 is otherwise fixedly coupled to its wire guide 6 for rotation therewith. At the same time, the rod 24 forms an anti-rotational retention for the wire guide 6 so as to ensure that the wire shuttle 5 maintains a previously assumed orientation.

A larger rod 30 is necessary for the connection between the outer linear motor 19 and the corresponding wire guide 6, and in order to make it stiff in an improved manner, the larger rod 30 is equipped with a reinforcing strut 31.

Figures 5 and 6 again show diagrammatically four linear drive units 14 and 18-20 without a wall mounting configuration. Each of the linear drives 14, 18-20 has a movable element 22 coupled to an extension 23. At this time, for the sake of clarity, the extended portion 23 is substantially shorter than that described in FIGS. 2 and 3.

The movable elements 22 of the linear actuators 14, 18 and 19 extend completely. The movable element 22 of the linear drive 20 is fully retracted. In the last case, the wire shuttle 5 is thus at the maximum distance from the warping drum 2. In this case, the wire shuttle 5 is placed, for example, in its rest position.

Figure 6 again shows the relative positions of a set of linear drives 14, 18-20. Two linear drives 14, 18 and 19, 20 are each disposed on one side of the plane formed by the wire guides 6. Among each of these groups, a linear drive unit 18, 19 is disposed at a small distance from the plane, and a linear drive unit 14, 20 is disposed at a greater distance from the plane. As is apparent from Fig. 2, the linear drives 14, 18 and 19, 20 in a group are each offset parallel to each other in the direction of movement of the wire guides 6, and thus parallel to the warping drum 2 axis.

In this way, if four modules 13 are used, it is possible to use a total of 128 individually driven wire guides, wherein the wire guides are arranged in a 1.6 m arc. Among this type of arc, the operator is able to reach all of the wire bobbins 5, and without additional assistance such as a ladder or ascending platform, for example, can be lined up or visually inspected.
