|Full Text||The invention relates to a yarn feeder for textile machines.
Yarn feeders are used to feed yarns to yarn using stations, such as
individual knitting stations in loop- forming textile machines. The
yarn feeders are separate devices, which must be secured in great
numbers to the machine. Depending on the use, special demands may
ensue for the yarn feeder that require a certain adaptation. From
the standpoint of the manufacturer of the yarn feeder, it is
therefore expedient if the yarn feeders are easily adaptable to
different situations, which can result from the type of textile
machine used in a given case or from a particular practical use.
Adaptation should be feasible at the least possible expense and with
the simplest possible means.
It is therefore the object of the invention to create a
versatile yarn feeder.
according to the features of the invention
This object is attained
The yarn feeder of the invention has an adjustable yarn guide
arrangement. The latter includes a yarn guide element, such as a
yarn eyelet, which can be adjusted between two different oblique
draw-off positions relative to the yarn guide drum. Drawing the
yarn off obliquely enables the traveling yarn to keep the yarn guide
drum clean. The adjustment is affected along a specified path.
Thus the yarn guide element can be transferred to at least two
different positions, in which the yarn travels along the lower rim
of the yarn guide drum at different angles. With a comparatively
shallower payout course, that is, in a first position in which the
yarn guide element is relatively high or in other words is only
slightly below the lower rim of the drum but in turn is at a greater
horizontal spacing from it, the yarn being paid out separates
relatively slowly from the windings located on the yarn guide drum
and is then paid out along the lower rim of the drum. This prevents
the situation in which the yarn being paid out could tear the
windings on the yarn guide drum down along with it. In this mode of
operation, the yarn feeder is especially suitable for spun yarns, in
which windings located side by side adhere relatively strongly to
one another because of the filaments protruding from the yarn.
In a second position, the yarn guide element is at a
comparatively great vertical spacing from the lower rim of the yarn
guide drum but in turn is set at a lesser horizontal spacing from
the pivot axis. The yarn being paid out is drawn downward
relatively steeply, so that it sweeps firmly over the lower rim of
the yarn guide drum. In this mode of operation, fluff deposits and
rings of fiber, which could form on the lower rim of the yarn guide
drum, are swept off especially well. This operation is especially
suitable for continuous-filament yarns.
The advantage of the adjustable yarn guide element is that the
payout angle of a yarn guided by the yarn guide element is
adjustable. If the yarn is changed, for instance by being cut
upstream of the yarn feeder and with a new yarn being spliced to the
remaining end of the old yarn, then the new yarn travels through the
yarn feeder to the textile machine without having to be threaded in
manually. The yarn guide element can be adapted accordingly in its
position to the filament properties of the yarn.
Another advantage is attained if an existing yarn feeler lever
(shutoff means) is capable of functioning in both adjusting
positions of the yarn guide element without having to be
repositioned. For instance, one yarn feeler lever is disposed such
that it scans the yarn in the vicinity of a fixed yarn eyelet. Any
adjustment of the yarn guide element does not substantially shift
the switching point of the yarn feeler.
The yarn feeder is furthermore preferably modularly designed.
The basic device has a basic carrier, which on one end has a
fastening device that is arranged for connection to the textile
machine, and that at a point spaced apart from this has a rotacably
supported, preferably vertically disposed shaft. The shaft is
arranged on one end for connection to a yarn guide drum and on its
other end is provided with a drive device. This device may be
embodied by a pulley or the like.
A coupling device is provided on the yarn feeder, and
additional modules can be connected to it. Thus the yarn feeder can
be adapted to different kinds of use by means of a plurality of
modules. Beginning with a basic device, a construction kit can thus
be created, with which a number of additional modules can be made.
For the yarn feeder manufacturer, this means that the many types
required can be made using only a few basic elements.
Essentially, the yarn feeder is formed as a basic device by
the parts that are each needed in a large number of applications.
These include the basic carrier, its fastening device for connection
to a machine, and a rotatably supported shaft along with a drive
device, and a yarn guide drum that is preferably secured
interchangeably to the shaft. Additional parts are connected to the
basic carrier via one or more coupling devices. The coupling
devices are disposed for instance on both sides of the shaft, which
makes greater freedom of design possible for the mounting of
The coupling device is preferably assigned a retaining device,
with which the counterpart is retained in its desired position. The
retaining device may be a clamping device, detent device, or other
kind of fastening means. The clamping device can for instance be
formed by a chucking device, which deforms the guide device somewhat
and thus brings about clamping by frictional engagement. The result
is secure bearing of the additional module and large-area
transmission of force as well as seating of the additional module
without rattling. The large-area force transmission makes it
possible to embody the coupling device of the same plastic as the
basic carrier, even if the coupling device is required to transmit
The additional module can be provided for receiving further
elements, which are preferably retained interchangeably. If the
additional module is a retainer that protrudes freely, for instance,
then different yarn guide elements can be secured to it. Bearings
for further supporting the shaft on the retainer can also be
provided, if necessary.
Another additional module may for instance be a yarn brake.
Depending on the application, various types of brake can be kept on
hand (driven, nondriven, with magnetic clamping of the brake
elements, spring clamping, etc.). A further fixture module may be a
friction module, which in addition to a friction drum that feeds the
yarn by frictional engagement has means for defining the wrap angle
of the yarn around the yarn guide drum. For bearing the yarn guide
means or similar parts that belong to the friction drum, suitable
connection means may also be provided on the underside of the basic
carrier. The basic carrier is preferably formed by a two-shell
housing, which is divided approximately horizontally. The housing
parts are then separably joined to one another, and as a result the
housing interior becomes accessible. Additional devices, such as
electric switches, circuits, bearings for yarn feeler levers and the
like, can be accommodated in the housing interior.

In Fig. 1, a modular yarn feeder 1 is shown, which is used to
feed a yarn 2 to a textile machine. The yarn feeder has a basic
carrier, embodied as a housing, with a fastening device 4 that
serves to secure the yarn feeder 1 to a suitable retaining device,
such as the retaining ring of a knitting machine.
The housing is constructed of two shells and has an upper
housing part 5 and a lower housing part 6, which abut one another or
fit in one another at a dividing seam 7. As seen from Fig. 2, the
housing serving as a basic carrier 3 has two bearing seats 9, 10 for
ball bearings 11, 12 for rotatably bearing a shaft 14. The shaft is
oriented approximately vertically and has a yarn guide drum 15 on
its lower end. This drum is preferably embodied in one piece as a
deep-drawn sheet-metal part or as a ceramic part. By means of a
retaining screw 17 screwed axially into a bl:_nd bore 16 of the shaft
14, the drum is joined to the shaft 14 in a manner fixed against
relative rotation. One or more drive disks 18, 19 are disposed on
the upper end of the shaft 14; via bearing devices, they are
supported rotatably on the shaft 14, and they can be coupled
rotatably to the shaft as needed by means of a coupling disk 21.
The bearing seats 9, 10 are formed by tubular extensions on
the upper and lower housing parts 5, 6. They are aligned with one
another and have a cylindrical chamber, opening toward the outside,
for receiving the respective ball bearing 11, 12. To assure the
alignment of the two bearing seats 9, 10 to one another, a tubular
extension 22 extending through the interior of the housing and
surrounding the shaft 14 is provided on the lower housing part 6; it
engages a corresponding receptacle 23 that :.s formed in the upper
housing part 5. The extension 22 and the receptacle 23 fit without
play in one another.
A plurality of coupling devices 25, 26, 27 for securing
additional modules are provided on the basic carrier 3. The
coupling device 25 is embodied on the basic carrier 3 between the
shaft 14 and the fastening device 4 and is shown separately in Fig.
3. The coupling device 25 includes a guide plate 28, which is
disposed parallel to a housing face 29 and is solidly joined to the
housing part 5 via ribs 31, 32. The guide plate 28, with the guide
face 29 and with its side toward the guide face 29, defines two
guide grooves 33, 34.
A portion 28a of the guide plate 28 protruding freely past the
rib 32 forms a fastening or clamping device for a foot that is meant
to be slipped onto the guide plate 28. A threaded peg 46 is fed
onto the portion 28a and extends, as shown in Fig. 2, into an
opening 37 of the housing part 5. Leading through this opening 37
is a fastening screw 38 whose head is braced on a suitable annular
shoulder 39 formed on the lower housing part 6. If the screw 38 is
tightened, this causes a certain deformation of the guide plate
In the yarn feeder shown in Figs. 1 and 2, the coupling device
25 includes a blind cap 41, which if needed completely covers the
coupling device 25. The clamshell-like blind cap 41 has an interior
42, in which two opposed clamping cleats 43, 44 extend that between
them define a slit. These cleats are arranged for being thrust into
the guide grooves 33, 34. Once the blind cap 41 has been slipped in
this way onto the coupling device 25, the fastening screw 38 can be
tightened, causing the portion 28a to firmly clamp the blind cap 41
with its clamping cleats 43, 44. In the sane way as the blind cap
41, arbitrary other additional modules can be secured to the
coupling device 25 and then each have a foot whose internal shape
conforms to the internal shape of the blind cap 41. One such
additional module can be seen in Fig. 5. A retainer 46 is secured
on the basic carrier 3 and fits over the drive disks 18, 19; on its
free end 47, it has a spring clamp 48 for securing a yarn guide
tubule 49. Still other devices can be secured to the arm 4 6 as
The coupling device 26 shown in Fig. 2 serves for instance to
secure a brake module 51. The coupling device 2 6 is formed by an
approximately rectangular recess or pocket, into which the brake
module is inserted by a base 52. The base 52 is guided and
positioned by the side faces of the recess formed in the housing
part 5. By means of a clamping screw 53, provided in the immediate
vicinity of the recess, the base 52 is retained in the recess.
The break module 51 is shown separately in Fig. 4. Its base
52 has two parts 56, 57, which are joined via a film hinge 54 and
can be locked to one another. This purpose is served by a detent
cleat 58, formed on the front free face end of the part 56, and a
corresponding detent recess 59 in the other part 57 is associated
with this cleat.
The two parts 56, 57 serve the purpose of axially displaceable
bearing of a brake carrier 61, which is formed by a bent wire
element. This element has two legs 62, 63, parallel to one another,
which are displaceably supported in suitable guides. The leg 62 is
braced on the part 57 via a compression spring 64 and prestresses
the brake carrier 61 in one direction (toward the shaft 14; see Fig.
2). On its free end, the leg 62 has a tappet 66, which cooperates
with a cam provided on the shaft 14.
Outside the base 62, the brake carrier 61 is provided with a
molded yarn guide piece 68, which via a rib 69 carries two brake
disks 71, 72, which are supported freely rotatably on the rib. The
break disks 71, 72 adhere magnetically to one another.
Additional fixtures may be a knot catcher 73 and a yarn inlet
eyelet 74, which are both retained by the fastening screw. As Fig.
1 shows, the yarn inlet eyelet 74 is open, so that the yarn 2 can
simply be placed in it from the side.
The knot catcher 73 is formed for instance by a metal sheet
provided with a narrow slit.
The fastening screw 53 can also serve to retain a yarn inlet
eyelet 75, which is disposed on an arm 7 6 above the drive disk 18.
The coupling device 27 is formed by the outer conical or
cylindrical face of the tubular extension 10, which extends into the
interior of the yarn guide drum 15. As Fig. 6 or Fig. 2 also shows,
the yarn guide drum 15 is therefore placed with its upper rim
relatively far away from the underside of the housing part 6,
approximately at the same level as a yarn guide eyelet 78, which is
molded as a fixed yarn guide eyelet on the lower housing part 6.
The interstice can be closed by a cover hood 79, which is slipped
for instance onto the extension 10. As Fig. 7 shows, the yarn guide
drum 15 can be supplemented with or replaced by a friction module
80. The friction module 80 includes the yarn guide drum 15 and a
friction disk 81 joined to the drum in a manner fixed against
relative rotation. The friction unit 80 also includes a setting
lever 82, which has a yarn guide eyelet 83 at approximately the
level of the transition between the friction disk 81 and the yarn
guide drum 15 and otherwise extends radially to the pivot axis of
the shaft 14. For pivotable bearing of the lever 82, clamping rings
84, 85 are slipped onto the coupling device 27 and seated on it;
between them, they clamp an annular bearing region of the lever 82.
The annular bearing region may be provided with one or more
protrusions that engage corresponding recesses in the clamping rings
84, 85, in order to fix the lever 82 in various detent positions.
In order to set the yarn feeder 1 for friction operation, in
many cases an outlet brake 91 is expedient or required. This brake
is preferably disposed between two yarn guide eyelets 93, 94 on the
outlet side. For fastening the outlet brake 91 detachably to the
yarn feeder, a base 95 is used, which is provided with a threaded
opening and is located below the fastening device 4. This allows
the outlet brake to be screwed on. It has a lower, approximately
horizontally disposed brake disk, which is carried by a pin 97
provided with an opening. An upper brake plate is supported
displaceably in the direction of the arrow on this pin and can be
locked in its upper position. This disk, by its own weight, presses
the yarn 2 against the brake disk 96.
The yarn feeder 1 has an adjustable yarn guide arrangement, to
which the yarn guide eyelet 93 belongs. To explain the structure
and function, reference will be made below to Figs. 8 through 11.
As seen from Figs. 8 and 9, the yarn guide eyelet 93 can be
transferred to at least two different positions and locked in those
positions. In the first position, shown in Fig. 8, the yarn guide
eyelet 93 is located a short distance below a plane E, defined by
the lower rim of the yarn guide drum 15, and is retained at a
relatively great spacing from the pivot axis D of the drum. The
preferably rectilinear path W along which the yarn guide eyelet 93
is adjustable or displaceable forms an acute angle with the pivot
axis D, as shown in Fig. 9.
The yarn guide eyelet 93 is carried by two substantially
parallel wire legs 105 extending away from it, which are guided in a
slot 106 formed in the housing. The slot 106, as shown in Figs. 10
and 11, is formed between the upper housing part 5 and the lower
housing part 6. For each leg 105, there is one slot 106 on each
side of the housing. In Figs. 10 and 11, the same reference
numerals are therefore used for the slots 106 and their details, and
the description applies equally to both slots 106.
The slot 106 includes a pocket, which is formed between the
upper housing part 5 and the lower housing part 6 and is open toward
the bottom. The pocket is formed on the part of the housing part 5
by two groove-like or channel-like indentations 107, 108, between
which a protrusion 109 is formed that is aimed at a corresponding
cheek 111 of the lower housing part 6. Between the cheek 111 and
the protrusion 109, however, a gap remains, through which the
applicable wire leg 105 can be thrust. The wire legs 105 yield
outward, however, so that on both ends of their path, which are
formed by the indentations 107, 108, they snap into place. The
channel-like indentations 107, 108 are thus both detent and guide
means at the same time, because they support the wire legs 105
nonpivotably. The wire legs 105 are also seated axially
nondisplaceably in the slot 106. To that end, ends bent inward or
angled in some other way are formed on the wire legs 105 and engage
the cheek 111, for instance, from behind, the cheek being embodied
as flat itself and extending between to outward-protruding ribs 114,
115. As needed, the ribs 114, 115 can either engage the
indentations 107, 108 or adjoin them. The narrow ribs 114 can for
instance engage the recess 108 and thus with their inner flank can
determine the alignment of the wire leg 105. The vertical
orientation of the yarn guide eyelet 93 is thus associated with the
lower housing part 6. The yarn guide eyelet 93 preferably allows a
certain lateral play for the yarn but is disposed centrally on the
housing. The yarn 2 travelling away from the yarn guide eyelet 93
and the pivot axis of the yarn guide drum 19 are thus preferably
both located in the same plane. The yarn feeder of Fig. 1 described
thus far functions as follows:
In operation, the yarn 2 is put in place and threaded in, as
shown. it extends through the inlet eyelet 74, through the space
between the brake plates 71, 72, to the yarn eyelet 78, and the yarn
2 in the interstice holds a yarn feeler lever 100, here supported
pivotably, in a raised position. Beginning at the yarn eyelet 78,
the yarn 2 passes in multiple windings around the yarn guide drum 15
and then travels, obliquely sweeping the lower rim of the drum to
the textile machine via the yarn guide eyeless 93, 94. Between the
yarn guide eyelets 93, 94, a further yarn feeler lever 101 rests on
the yarn, in order to monitor its tension. The yarn feeler lever
101 is connected to a switch, which furnishes a switching signal
whenever the yarn feeler lever 101 drops below a minimum height.
The yarn feeler lever 101 is disposed such that when the yarn
is held taught, in each setting position of the yarn guide element
93, it is held in the same or at least nearly the same position.
The rated position of the feeler lever 101 is as a result
independent of the setting of the yarn guide element 93. This is
attained by means of a pivotable bearing of the yarn feeler lever
101 in the vicinity of the pivot axis D and by a relatively long
lever length; the yarn 2 is scanned in the vicinity of the fixed
yarn guide eyelet 94.
If needed, further yarn feeler elements may be provided, whose
rated and switching positions are equally unaffected by the
adjustment of the adjustable yarn guide arrangement.
In operation, the yarn guide drum 15 is driven to rotate and
thus feeds specified quantities of yarn.
For instance, if a spun yarn, which has relatively many
filaments protruding from the yarn, is to be processed, then the
setting of the yarn feeder 1 as shown in Fig. 8 is preferred. The
yarn guide eyelet 93 here is in an upper position at a relatively
slight spacing below the plane E, but at a greater spacing from the
pivot axis D. The yarn 2 is drawn off relatively shallowly and thus
deviates rather slowly from the package located on the yarn guide
drum 15. This prevents the yarn 2 being paid out from tearing
windings of the package downward.
If a comparatively smooth continuous-filament yarn is to be
processed, then the yarn 2 is torn off upstream of the yarn feeder
1, and the new yarn is knotted to the end of the old yarn.
Furthermore, for setting to the smoother continuous-filament yarn,
the yarn guide eyelet 93 is transferred downward to the position
shown in Fig. 9, in which it is farther away from the plane E but in
turn closer to the pivot axis D. This spacing, however, is still
greater than the diameter of the lower rim of the yarn guide drum
15. The yarn is now drawn off relatively steeply, so that it
reliably sweeps over the rim of the yarn guide drum 15 and strips
off any fluff or the like present there.
For adjusting the yarn guard eyelet, the wire legs 105
are pressed together, counter to their own spring force, so that
they emerge from the respective indentations 107 and 108 (see Fig.
10). The element formed by the yarn guide eyelet 93 and the wire
legs 105 can be displaced in this condition along the path W. Once
it is released at the end of the path, the wire legs 105 snap back
into the respective indentations 107 or 108, and the yarn guide
eyelet 93 is locked in its new position. The path W can be linear,
or in other words a straight line. If needed, it can also be
curved, for instance by disposing the yarn guide eyelet 93 on the
end of a pivotably supported arm.
If needed, intermediate positions can be provided, by forming
suitable grooves in the protrusions 109. If the yarn guide drum 15
is replaced with the friction unit 80 of Fig. 7, then the yarn 2
wrapping around the friction disk 81 is correspondingly carried
along and advanced. Replacing the yarn guide drum 15 with the
friction unit 80 thus makes it possible to vary the functional
The brake module 51 can also be replaced by a non- driven yarn
brake module. The yarn feeder 1 can also be refitted by removing
the blind cap 41 and replacing it with the arm 46 (Fig. 5).
For a modular yarn feeder 1, a basic carrier 3 is a basic
component on which additional modules can be secured as needed by
suitable coupling devices. This makes the yarn feeder more
adaptable to different kinds of use and situations.
