Abstract
A hollow multi-layered yarn package includes layers of mutually concentric annular yarn courses (36) in which the yarn passes between successive courses at regions (37) which are staggered about the axis of the package. The package is produced by coiling the yarn on a yarn coiler and then transferring the coiled yarn to a rotating yarn receiver (32). To form the concentric annular courses the coiler is moved towards or away from the axis of rotation of the yarn receiver (32) after each successive annular course has been formed. <IMAGE>
Description
SPECIFICATION
Multi-layer yarn package production
The invention relates to a method of forming a hollow, multi-layered yarn package (cheese) from substantially circular yarn loops on a rotating yarn receiving means. The invention also relates to an apparatus for performing such a method and to a yarn package (cheese) produced by the method and with the apparatus.
German Auslegeschrift 1,138,349 discloses a method of making yarn packages (cheese) in which yarn loops are placed superposed in a plurality of layers in a single circular course on a rotary disc by means of a feeder device.
Particularly with certain types of yarn, a cheese formed in this manner lacks the required internal strength, because the individual yarn loops and the annularly deposited rings which they form may shift reciprocally, which leads to the cheese overturning.
It is an object of the invention to make the interior construction of a yarn package (cheese) more stable and to provide a method and apparatus for this purpose.
According to one aspect of the present invention there is provided a method of forming a hollow multi-layered yarn package from coiled yarn, comprising forming the coiled yarn into layers of mutually concentric annular courses on rotating yarn receiving means whereby the yarn passes between successive courses at annularly staggered regions.
According to another aspect of the present invention there is provided an apparatus for forming a hollow multi-layered yarn package, comprising coiler means for coiling the yarn; yarn receiving means rotatable about an axis thereof and located below the coiler means for receiving from the coiler means the coiled yarn to form layers of mutually concentric annular courses; and means for providing relative adjustment between the coiler means and the axis of rotation of the yarn receiving means to pass the coiled yarn between successive courses at annular staggered regions.
According to another aspect of the present invention there is provided a hollow multi-layered yarn package made by the method defined in the preceding paragraph and comprising coiled yarn arranged in layers of mutually concentric annular yarn courses in which the yarn passes between successive courses at annularly staggered regions.
An embodiment of the present invention will now be described by way of example and with
reference to the accompanying drawings in which:
Figure 1 shows schematically a yarn cheese forming machine in side elevation;
Figure 2 shows a sectional view along line 2-2 in Figure 1;
Figure 3 shows a sectional view along line
3-3 in Figure 1; and
Figures 4 to 7 show a plurality of stages in the
production of a yarn package embodying the present invention.
As may be seen from Figures 1 and 2, a bearing plate 3 is movable up and down on two stationary vertical rods 1,2, serving as a sliding guideway, by means of a screw spindle 6 driven by a motor 4 through a drive belt 5. Mounted on the bearing plate 3 on a swivel pin 7 is a pivot arm 8 which is adjustable by means of a hydraulic cylinder 9 into various positions, of which two positions are illustrated in Figure 2. At the free end of the pivot arm 8 is arranged a yarn coiler device 11 which is driven through a belt 12 by a motor 13, likewise mounted on the pivot arm 8.The coiler device 11 is of conventional construction (German
Auslegeschrift 1,138,349 and German
Offenlegungsschrift 2,828,535) and comprises as essential elements a hollow shaft 1 4 for the introduction of the yarn to be fed, a plurality of screw spindles 1 5 driven in rotation and a coiler blade 1 6 which wraps the fed yarn round the screw spindles 1 5. The coiler device 11 may comprise for example six downwardly projecting screw spindles. The yarn which is fed through the hollow shaft 14 and placed by the coiler blade 1 6 into the top threads of the screw spindles 1 5 finally runs off the bottom ends of the screw spindles 15 in the form of circular yarn loops.A feeler lever 1 7 which co-operates with an inductive sensor 1 8 is also mounted pivotably on the pivot arm 8. The motor 4 is mounted stationary like the rods 1,2, which is not shown in the schematic Figure 1.
Beneath the arrangement described (Figure 1) a second pivot arm 22 is mounted pivotably on a fixed swivel pin 21. The pivot arm 22 carries two rotatably mounted pulleys 23, 24, of which the pulley 23 is driven by a motor 25, likewise attached to the pivot arm 22. The two pulleys 23, 24 are associated in rotation by means of a friction belt 26. A carriage 31 is slidable horizontally in a guideway formed by rails 27, 28, 29, as shown in Figure 3. On its surface, which is likewise oriented horizontally, the carriage carries a plurality of, for example three, rotatably mounted yarn receiving discs 32, onto which the substantially circular yarn coils leaving the coiler device 11 are required to be placed. The pivot arm 22 is adjustable between the two positions illustrated in Figure 3 by means of a hydraulic cylinder 33.In the position shown by thick lines in
Figure 3 no contact exists between the friction, belt 26 and the first disc 32 of the carriage 31. In the other position, the hydraulic cylinder 33 presses the friction belt 26 travelling round the pulley 24 against the outer circumference of the disc 32, so that the feed disc 32 is set in rotation when the friction belt 26 revolves. In order to ensure an accurate relative positioning of the pulley 24 on the one hand and of the various discs 32 on the other hand in each case, the carriage 31 has a plurality of notches 34, into which a projection 35 standing out laterally from the pivot arm 22 can engage.As soon as a yarn package or cheese has been completed on the first disc 32 of the carriage 31, the carriage 31 is advanced in its guide rails 27, 28, 29 until the projection 35 engages into the next notch 34, so that the friction belt 26 can then be correctly applied to the next disc 32 by means of the hydraulic cylinder 33.
The functioning of the described apparatus and the construction of a yarn package (cheese) will be explained with reference to Figures 4 to 7. The arrow A in Figure 4 indicates the direction of rotation of the disc 32. It is assumed in Figure 4 that the coiler device 11 occupies the position shown in Figure 2 by thick lines. In this position of the coilerdevice 11, the circular yarn coils 36 falling from the screw spindles 1 5 are placed successively, and mutually laterally staggered in each case, in an outer annular course upon the rotating disc 32. The recumbent mutually overlapping yarn coils then assume, in this annular course, somewhat the shape of a helicoidal spring with its turns pressed flat.As soon as the outer annular course has been filled with yarn loops, the coiler device 11 is brought into the position shown in Figure 2 by thin lines by actuating the hydraulic cylinder 9. In this position the circular yarn coils leaving the coiler device 11 are placed in a second annular course on the disc 32, whilst this second annular course lies concentrically to the first course (Figure 4), but has a smaller radius than the latter. In Figure 5 the transition point from the outer to the inner annular course is designated by the reference numeral 37. Figure 6 shows the yarn coils 36 on the inner annular course, omitting the yarn coil placed on the outer annular course.
When the inner annular course has been completely filled with yarn loops 36, the coiler device 11 is returned into the position in which the yarn coils 36 are placed upon the outer annular course, and now in fact onto the yarn coils 36 previously placed in that course. The transition point from the inner to the outer annular course is designated by the reference numeral 38 in
Figure 7. In this way a yarn package having an inner cavity 39 and comprising a large number of layers is produced, in which the yarn coils lie in two mutually concentric circular courses each of different radius, whilst the individual circular courses "cross" each other as it were at the transition points 37, 38 and thereby impart a particularly intimate cohesion to the yarn package.
The drive motors 13 and 25 previously described are of infinitely variable speed. The feeding speed of the yarn coils 36 and the rotary speed of the disc 32 can therefore be adjusted infinitely. The adjustment is made so that any superimposition of the transition points 37, 38 (crossing points) in the yarn package being formed on the disc 32 is avoided. These points therefore lie mutually staggered and are distributed as uniformly as possible in the entire yarn package so as to give it the required stability. The apparatus described may be associated with an electronic control device which appropriately varies the rotary speeds of the coiler device 11 and of the disc 32 required during the placing of the inner and outer courses at the correct time.This control device also simultaneously regulates the drive motor 4, which slides the coiler device 11 gradually upwards as the yarn package grows.
At the start of the forming operation the coiler device 11 is slid downwards (by means of the screw spindle 6) until the feeler lever 1 7 strikes the feed disc 32. The coiler device 11 then travels to the correct height through the intermediary of the control device mentioned. The motors 1 3 and 25 are simuitaneously switched on. After the preselected height of the yarn package is reached, the control device switches off the machine automatically, the carriage 31 is unlocked and slid on manually by one station, so that the next disc 32 of the carriage 31 is located beneath the coiler device 11. The formation cycle then commences afresh.
In the apparatus illustrated and described the yarn package (cheese) is built up on a disc 32. It would also be possible for a cylindrical tank, on the base of which the yarn package is built up in the prescribed manner, to stand on the rotating disc 32. Instead of sliding the coiler device 11 slowly upwards during the formation of the cheese, it would be possible for the disc 32 to be moved slowly downwards.
Similar considerations also apply to the relative lateral adjustment of coiler device 11 and disc 32 at the transition from the one to the other annular course, i.e., instead of moving the coiler device 11 sideways by means of the pivot arm 8, it would also be possible for the disc 32 to undergo a corresponding lateral movement, Lastly, the yarn package described may also comprise more than two annular courses with yarn coils 36 placed on it in a plurality of layers, and with corresponding transition points 37, 38.
