Description
SPECIFICATION
Device for continuously producing a ball of textile yarn
The present invention relates to a device for arranging textile yarn into a continuous toroidal ball.
In the textile industry, textile yarn undergoes a certain number of chemical, mechanical and/or heat treatments. These treatments were formerly performed sequentially at separate treatment stations.
Between treatments at different stations, the yarn was stored, for instance in skeins, which were often collected manually at the outlet of one treatment station and then transported in batches to the inlet of the next station.
In order to increase productivity and reduce manufacturing costs, an attempt has been made to carry out the various above-mentioned treatments continuously, by juxtaposing the treatment stations, so as to reduce the storage and transfer operations.
One difficulty is that the different stations do not operate at the same speed, so that the yarn must be treated for different lengths of time at different stations. To solve this problem, the yarn can be continuously stored between treatments, for instance on conveyor belts, from which it is then removed for a subsequent treatment. On the other hand, certain machines, such as machines for fixing dyes by a heat process, require that the yarn remain in a steam chamber for a relatively long period. To avoid the necessity of making a machine excessively large, it is important to treat the greatest possible length of yarn at one time.
One device which is widely used for storing the yarn continuously is described in French Patents 1,374,340 and 1,488,073. This device comprises a horizontal removal head which places the yarn on a conveyor belt in overlapping or adjacent circles spaced apart along the belt. This device is still widely used satisfactorily for numerous applications.
Nevertheless, the storage capacity of such a system is relatively small.
The object of the present invention is to provide a simple and effective device for storing yarn in a three-dimensional pattern on a conveyor belt, thereby considerably increasing the storage capacity of a conveyor belt of a given length.
The conditioning device in accordance with one embodiment of the invention comprises a first rotary member driven at a first constant speed around a first axis of rotation and a second rotary member driven at a second constant speed around a second axis of rotation. The second axis is parallel to and spaced from the first axis. The first rotary member is eccentric to and may be mounted in an eccentric cavity provided in the second rotary member. The first rotary member has a flat circular surface. The first rotary member contains a passage for the textile yarn. The passage includes an axial, radially central, entrance channel, a radially outwardly extending intermediate channel perpendicular to the entrance channel, and an outlet debouching onto the flat circular surface at a point which is radially displaced from both axes.The axial entrance channel preferably lies along the first axis. Hollow tubular means for guiding the advancing yarn to the inlet of the entrance channel from a position on the second axis and for bringing it to the inlet of the axial entrance channel arranged along the first axis is also provided.
In accordance with one embodiment, the first rotary member is driven for rotation about the first axis by a mechanism comprising a disk which is rigidly connected to the second rotary member. A plurality of independently rotatable rollers are mounted in a circle near the periphery of the disk. A drum, located within the circle of the rollers, is mounted at the free end of the first rotary member at a point preferably not on the second axis. Each roller has two axially spaced peripheral circular tracks for carrying two separate belts. A first belt travels on the respective first tracks of at least some of the rollers to drive them at a constant speed.A second belt travels on the second respective tracks of each roller and also passes around the drum mounted rigidly on the first rotary member and off-center with respect to the disk, thereby to drive the first rotary member at a second constant speed.
The above-described mechanism feeds the textile yarn out in a series of overlapping circles of relatively small diameter arranged about the periphery of a large, substantially vertical circle, so as to form a toroid. As additional layers of small circles are added, the ball of yarn being formed takes the form of a tubulartoroid. A very large length of textile yarn can be stored in such a toroid of very short length.
Other objects and features of the invention will be apparent from the following description and the accompanying drawings.

Figure 6A is a sectional view through the device shown in Figure 1,taken from the line l-l, and showing diagrammatically the drive mechanism for the first rotary member in a first position, corresponding to the position shown in Figure 1.
Figure 6B shows the mechanism of Figure 6A after one-quarter of a revolution of the disk 30.
Figure 1 shows a first preferred embodiment of the apparatus 10 of the invention. The device 10 comprises a first rotary member 13 which is driven at a first constant speed of rotation around a first axis of rotation 14 and a second rotary member 11 which is driven at a second constant speed of rotation around a second axis of rotation 12.
The second rotary member 11 comprises a sub
stantially cylindrical part 1 1a which is rigidly con
nected with a second block 11 b, also cylindrical,
which is of a smaller diameter than the part 11 a. The
two elements 11 a and 11 b can be made as one piece
or can be made separately and secured together by
conventional means. The second rotary member 11
is mounted for rotation around second axis 12 on a
frame 15 by means of bearings 16. The bearings 16
may consist, as shown in Figure 1, of ball bearings or
of any other suitable bearings.
The part 1 1a has an eccentric cylindrical recess 17.
The axis of-the recess 17 is also the axis 12 of the first
rotary member. The recess 17 is adapted to contain a
portion of the first rotary member 13. The front
surface 13' of the first rotary member is located in
the plane of the front surface 11' of the second rotary
member 11. The first rotary member 13 preferably
includes a first, front, circular disk-shaped part 1 3a
and a second, rear circular disk-shaped part 13b.The second part 13b is secured to the first part 13a by
conventional fastening means such as a bolt 18
whose head is embedded in the thickness of the part
13b. The combination of the two parts 13a and 13b is
rigidly mounted on the forward end of a shaft 13c.In
order to facilitate this, the part 1 3b has a cylindrical
base portion 19 and a central borehole 19' accom
modating the end of the shaft 13c.
The shaft 13c has a hollow central bore 20, which
defines an axial entrance channel for the textile yarn,
as will be described below. The bore 20 has a ring 21
and 22 located at either axial end. The inner diameter
of the rings 21 and 22 is slightly less than the
diameter of the central bore 20. The forward end of
the entrance channel 20 which is defined by the ring
22 communicates with an intermediate channel 23
which has the form of a radially extending, semi
circular groove, and is defined in the circular part 1 3a at the surface of contact of the two adjacent faces of
the circular parts 13a and 13b. At their junction, the
entrance channel 20 and the intermediate passage
23 form a right-angle bend.An outlet 24 at the
radially outward end of the passage 23 forms
another right angle bend with the intermediate
channel 23 and debouches on the front surface 13' of
the part 13a. The outlet 24 is defined by a third ring
25 identical to the rings 21 and 22.
As will be described below, textile yarn is intro
duced along the axis of rotation 12 of the second
rotary member 11 and is brought by various means,
described below, to the axis of rotation 14 of the first
rotary member 13. The yarn then passes axially
through the entrance channel 20, through the inter
mediate passage 23 where it is affected by the
centrifugal force of the rotation of the rotary parts of
the ball-forming device 10, and debouches via the
outlet 24 in the plane of the surface 13'.
At the inlet end of the shaft 13c is a cylindrical
element 13d that is coaxial with the shaft 13c. The piece 13d can be made in one piece with the shaft
13c or can be mounted on it by appropriate conven
tional means. The piece 13d has a central borehole
26 and a circular peripheral track 27 on its exterior
surface. An endless belt 28, the purpose of which will
be described below, travels around the track 27.
A platform 29 supports the frame 15, which is mounted on it by known conventional means. The rear end of the rotary member 11, i.e. the end which is opposite the surface 11', supports a disk 30 which is mounted in known manner on the cylindrical block 11 b. The disk 30 carries a plurality of rollers 31, preferably seven in number, arranged uniformly around a circle concentric with the disk 30. Each roller 31 is mounted rotatably on a respective pin 32 by means of a ball bearing 233 or by any other suitable means. The pins 32 are secured to the disk 30. Each of the rollers 31 includes two axially spaced cylindrical parts 31 a and 31 b of the same diameter separated buy a dividing piece 31c.The dividing piece 31 c is also cylindrical, but it has a diameter larger than that of the parts 31 a and 31 b so as to constitute a rim separating the two peripheral travel tracks defined at the parts 31a and 31 b. The two tracks thus defined by the peripheral surfaces of the parts 31 a and 31 b of the rollers 31 serve as supports for two belts 34 and 28, which constitute the means for driving the first rotary member 13, as described below in one direction.
A drive belt 35 rotates the second rotary member 11 at one constant speed in the same one direction.
A double-bent or S-shaped feed tube 37 is arranged with its inlet end 37a oriented along axis 12 and with its outlet end 37b oriented along axis 14 and disposed in borehole 26. The feed tube 37 is rotatable about axis 12. The feed tube 37 brings the textile yarn, which enters along the axis 12, into line with the axis 14, and the axis 14, when the tube 37 rotates, describes a cylinder whose axis is the axis 12.
The device 10 is intended to produce a cylindrical toroid of textile yarn. The toroid is formed of a plurality of coaxial layers, each of which is a toroid comprising a series of overlapping, relatively small circles arranged around the circumference of a larger circle. Each layer, i.e. each large circle, lies substantially in a vertical plane. The radius of each of the smaller circles equals the distance between the outlet 24 and the axis 14 of rotation of the first rotary member 13. The center of each of the larger circles is located on the axis 12 of the second rotary member 11.
In order to produce the cylindrical toroid, the second rotary member 11 is driven at a first constant speed by means of the belt 35 that runs around the peripheral surface of the part 1 la of the second rotary member 11. This rotation occurs around the axis 12, which is fixed with respect to the frame 15 and the body 29. The first rotary members 13, which is eccentric with respect to the fixed axis 12, is driven by a more complicated mechanism the operation of which is described in further detail with reference to
Figure 1 and Figures 6A and 6B.
The disk 30, which is rigidly and coaxially connected with the second rotary member 11, is driven at the first constant speed by the belt 35. The rollers 31, which are mounted on the disk 30, are accordingly also rotated at the first constant speed around the axis of rotation 12. As shown in Figures 6A and 6B, the belt 34 which rests at all times on the peripheral surface of the cylindrical parts 31a of four of the rollers 31, drives each of these four rollers 31 at a predetermined speed. The belt 28, as shown most clearly in Figures 6A and 6B, lies on the peripheral surfaces of the cylindrical parts 31b of each of the rollers 31, and also describes a loop 28a that is located between two of the adjacent rollers 31 and that passes around the peripheral surface 27 of the cylindrical element 13d located at one end of the shaft 13c of the first rotary member 13.As the rollers 31 are driven around the axis 12 by the rotation of the disk 30 on which they are mounted, and as the rollers 31 are simultaneously driven around their respective axes 32 by the belt 34, the belt 28 is driven by the frictional engagement between it and the travel tracks 31 b of the cylindrical elements 13b. The belt 28 in turn drives the cylindrical element or drum 13d at 28a and, therefore, drives the second rotary member 13, via the shaft 13c, at a second constant speed which is determined by the speed of belt 34 and by the outer diameter of drum 13d. This mechanism thus makes it possible to produce the double rotary movement of the rotary members 11 and 13.
Figure 2 shows another embodiment 40 of the device in accordance with the invention. The device 40 comprises, a first rotary member 43 driven at a constant speed around an axis of rotation 44 and a second rotary member 41 driven at constant speed around a fixed axis of rotation 42 which is eccentric to the axis 44. The second rotary member 41 is formed essentially of a rotary drum 45 mounted on bearings 46, shown diagrammatically. The drum 45 is supported by a frame comprising two supports 49 and 50 mounted on a platform 51 by means of screws or bolts 52 and 53 or any other suitable known means. The drum 45 is encased in a cylindrical sheathing 54 located axially centrally between the supports 49 and 50. An annular part 55 which is rigidly mounted on the support 50 closes the front face of the block formed by the drum 45 and its sheathing 54.To one end of the rotary drum 45 there is affixed a pulley 47 having a groove 48 in which there is applied a driven belt (not shown).
The first rotary member 43 is formed essentially, as in the preceding embodiment, of a rotary disk made in two adjacent and coaxial parts 43a and 43b which are securely attached to the front end of a shaft 43c. The shaft 43c is mounted on bearings 56, preferably ball bearings, so as to be able to turn freely around the axis of rotation 44. The bearings 56 are mounted on the drum 45 in such a manner that the axis 44 of the first rotary member 43 is parallel to and spaced a predetermined distance from the axis 42 of the second rotary member 41. The disks 43a and 43b are housed in a hollow cylindrical part 57.
The cylindrical part 57 is equipped with an annular edge flange 58, arranged in the plane of the front face of the first rotary member 43. The hollow cylindrical part 57 is fastened to the drum 45, for instance by means of a bolt 59, and serves as a
protective shield for the first rotary member 13
located in its central recess 57a.
As in the first embodiment, the shaft 43c is hollow and has at each end a ring 60 and 61, respectively, which define an entrance channel 62 for the passage of the textile yarn. The channel 62 communicates with an intermediate radially extending channel 63 having the form of a groove on the surface of the disk 43a that adjoins the disk 43b. The intermediate channel 63 debouches through the front face of the first rotary member via a ring 64 identical to the rings 60 and 61. The outlet ring 64 constitutes the outlet channel for the textile yarn intended to be wound into a toroidal "ball".
The second rotary member 41 is driven by a drive belt (not shown) engaging the pulley 47. The first rotary member 43 can be driven by a device (not shown) similar to that used in the embodiment of
Figure 1, which was described with reference to
Figures 1, 6A and 6B. It is sufficient to equip the pulley 47 with rollers like rollers 31 and to contact the rear end of the shaft 43c with a drum like drum 13d driven buy a belt like belt 28, all of these elements being identical to the corresponding elements shown in Figure 1.
The embodiment of Figure 3 differs somewhat in its principle of operation from the two embodiments described previously. The first rotary member 73 is driven by a mechanism which is separate from the mechanism that drives the second rotary member 71. The two drive mechanisms are coupled by a deformable, flexible mechanical connection 108 which also guides the textile yarn during its passage through the device of Figure 3, as described below, bringing the yarn from its original path which lies along the axis of of rotation 72 of the second rotary member to the entrance of the axial passage 88 arranged within the drive shaft 73d of the first rotary member 73.
The device 70 shown comprises, like the devices previously described, a first rotary member 73, driven at a constant speed around a first axis of rotation 74-, and a second rotary member 71, driven at a constant speed of rotation around a second axis of rotation 72. The second rotary member 71 comprises a drum 71 a of generally cylindrical shape mounted for rotation on a frame 75 by means of ball bearings 76. The frame 75 is fastened by screws 77 to a horizontal bracket 78. The rear end of the drum 71a is secured to a pulley 71b. The pulley 71 b is shown formed in one piece with the drum 71a. But, it could also be developed separately and be attached to the drum 71 a by conventional means. The front end of the drum 71 a is covered buy a disk 71 c mounted on the drum 71a by means, for instance, of a screw 79. The disk 71 c serves as support for a cap 71 d connected to the disk 71 c by means of a screw 80. The cap 71 d serves as a protective shield for the first rotary member 73. The pulley 71 b has a peripheral groove 81 adapted to engage a V-belt (not shown, the purpose of which is to rotate the pulley 71 b and the assembly of the parts which are secured to it, i.e. the drum 71a, the disk71c and the cap 71d.
A ring 82, connected to the frame 75 by means of a screw 83, prevents the axial displacement in the downstream direction of the second rotary member 71. An annular part 84 fastened to the bracket 78 by a bolt 85 prevents any rearward axial displacement of the second rotary member 71.
The first rotary member 73 is substantially identic alto the first rotary member 43 described with reference to Figure 2. It comprises a first disk 73a, a second disk 73b, a hollow cylindrical sleeve 73c and a hollow shaft 73d. The first disk 73a is mounted by means of a screw 86 on the second disk 73b, which is integral with the hollow cylindrical sleeve 73d. The disks 73a and 73b are mounted by means of the sleeve 73c on the hollow shaft 73d, whose axis coincides with the axis of rotation 74 of the first rotary member 73. A screw 87, embedded in the thickness of the wall of the sleeve 73c, secures the sleeve 73c and the shaft 73d to each other. As in the embodiments previously described, the axial entrance channel 88 provided within the hollow shaft 73d has a ring 89 and 90 fastened to it at each end.
An intermediate channel 91, arranged within the thickness of the disk 73a, communicates with the entrance channel 88, with which the intermediate channel 91 forms a right angle bend. The intermediate channel 91 has an outlet opening 92 defined by a ring 93 identical to the rings 89 and 90. The rotary shaft 73d passes through the second rotary member 71, with respect to which it can turn freely around the first axis of rotation 74 because of ball bearings 94.
In this embodiment, the first rotary member is driven by means of a drive block unit 100. The drive block unit 100 includes a frame 101 mounted on the bracket 78 by means of screws 102. The frame 101 serves as the support for two bearings 103 and 104.
A rotary shaft 105, mounted on the bearings 103 and 104, has a pulley 106 mounted on its rear end. The shaft 105 is hollow and at its front end has a ring 107 similar to the rings 89,90 and 93. The front end of the shaft 105 is connected to the rear end ofthe shaft 73d by a flexible member 108, which may be a length of tubing of flexible material but is preferably a spiral spring with close turns. A conical protective mask 110 connects the rear end of the device 70 to the front end of the mechanism 100.
The pulley 106 has a peripheral groove 109 adapted to hold a V-belt (not shown). The purpose of the belt is to drive the pulley 106 and the rotary shaft 105 to which it is fastened and, via the flexible member 108, to drive the rotary shaft 73d and the first rotary member 73 to which it is fastened. The shaft 105 of lone drive mechanism 100 is arranged along the fixed axis 72 of the second rotary member 71. As a result, the rear end of the flexible connecting member 108 rotates around the fixed axis 72, while the front end of the flexible connecting member 108, which is secured to the shaft 73d, both rotates about its own axis and describes a circle centered on the axis 72. The flexible connecting member 108 therefore describes a cone as it moves.
As in the case of the two embodiments described previously, the first rotary member 73 and the second rotary member 71 both rotate simultaneously. The second rotary member 71 rotates around a fixed axis 72 and the first rotary member rotating around an axis 74 which is parallel to and spaced from the fixed axis 72 and which itself rotates about the fixed axis 72 at a constant distance therefrom. In the case of Figure 3, the textile yarn enters the rear end of the drive mechanism 100, passes through the hollow shaft 105 along the fixed axis 72, passes through the flexible connecting member 108 and enters the axial entrance channel 88 of the hollow shaft 73d. The yarn passes through the entrance channel 88 and the radial intermediate channel 91 and then reemerges at the front end of the first rotary member 73 through the outlet 92.As the yarn emerges from the outlet 92, it is arranged in a toroidal "ball" in the same manner as with the previously described embodiments.
Figure 4A is a perspective view of a toroidal "ball"' of textile yarn produced by the device of the invention. It is in the shape of a tubulartoroid 120 each section of which, cut along a plane perpendicu- lartothe ball's longitudinal axis, is in the form of a ring 121 composed of a series of small circles 122 of equal size whose centers are spaced about a larger circle. The center of the larger circle lies on the longitudinal axis of the toroid 120. Two gutters and 124, each formed of a cylindrical segment or of several flat panels joined together, are positioned with their opposing faces supporting the "ball" 120 as it forms as the yarn emerges from the outlet of the ball-forming device.The small circles 122 of yarn are produced by the relatively fast rotation of the first rotary member of the ball-forming device. The shift of consecutively-formed ones of the small circles about the circumference of the larger circle is due to the relatively slow rotation of the second rotary member. During the period of time within which the first rotary member describes a complete turn, the second rotary member will have passed over a circular arc corresponding to the distance between the centers of two adjacent small circles 122.
In the example shown in Figure 4A, the distance between the outlet orifice for the textile threads and the axis of rotation of the first rotary member is less than the distance between the respective axes of the first and second rotary members. As a result, the axis of the second rotary member, which remains fixed at the center 125 of the pattern, and which corresponds to the axis of the ball 120, is located outside of each of the small circles 122. On the other hand, in the example illustrated in Figure 4B, the axis of the "ball" is inside each of the small circles 122' which are produced by the motion of the first rotary? member. In this case, the distance between the outlet orifice and the axis of the first rotary member is greater than the distance between the axes of rotation of the first and second rotary members.
Figure 5 shows a blank disk 130 that is preferably mounted in front of the ball-winding device. The disk 130 serves as a guide in which the first few turns of the toroidal "ball"1 20 are wrapped as they are formed. The disk 130 has an annular part 131 and a series of flexible blades 132 directed radially therefrom toward the center of the disk 130. In Figure 5, these blades are shown in their position of rest.
While the "ball" is being wound, the blades 132 are extended perpendicular to the plane of the annulus 131 and surround the "ball", resting against its peripheral surface.
In order that the first turns of yarn can be formed at the outlet, a rigid plug (not shown) is previously placed within the inner diameter of the annulus 131, where it is held in place by the blades 132. The gutters 123 and 124 are disposed in front of the disk 130 to receive the "ball". The yarn, as it emerges from the outlet, is then engaged between the face of the first rotary member and the adjacent end face of the plug, where it accumulates in the toroidal pattern described above. As the turns of yarn accumulate, they progressively push the plug away from the face of the first rotary member. The plug can then be recovered at the end of the gutters 123 and 124 remote from the' face of the first rotary member. As the "ball" fills the gutters 123 and 124 and begins to protrude beyond them, it is deposited on a conveyor belt (not shown).
When the textile yarns are in the channel of the first rotary member of the ball-forming of the invention, they are pushed up to the outlet eye of the second rotary member by means of a jet of compressed air produced by a conventional device not shown in the drawing.
The different variants of the ball-winding device described solve the problem of temporary storage of a large length oftextileyarn in a relatively limited space.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
