Closing sleeve for dyeing spindles

The subject of the invention is a locking sleeve for dyeing spindles with a resiliently supported pressure plate, which is arranged axially displaceably on the locking sleeve sleeve in the direction of the upper end of the sleeve is which sleeve can be brought into positive engagement with the end of the dyeing spindle.

There are generic dye spindles known in which the spring used to press the pressure plate through a screwable on the top of the locking sleeve bushing Nut is fixed under tension. The operation of "closing sleeves" equipped in this way, however, often requires a considerable amount of force, which is particularly evident in the often considerable height arrangement of the locking sleeves is detrimental to the operator. There are also closure sleeves known in which the The spring is tensioned by means of a pressure part that can be displaced on the upper end of the dyeing spindle. Also at this version is the elaborate operability of Disadvantage.

The object of the invention is, in particular, i.e. Additionally to the tasks resulting from the description and claims, a locking sleeve of the generic type in terms of production technology, simpler, more cost-saving Way to train useful, such that tensioning and loosening using the least amount of forces and simple operation can be done.

This object is achieved by the invention specified in claim 1.

The subclaims represent advantageous developments of the invention.

As a result of such a configuration is a generic one Closure sleeve created of increased practical value. In addition to a simplified production is an easy one Ease of use achieved. The compression spring can be designed to be very strong for secure, firm axial bracing; the tensioned position fixation can nevertheless take place in a time-saving manner in a fluid sequence of movements. There is no tactile alignment of the locking sleeve bushing necessary for storing the holding means, since the interlocking of the holding means takes place independently of an opposing position to be balanced advantages for the production are achieved; no custom-fit, cost-increasing designs are necessary. However, it is also a significant relief

809831/01 19

-4- 15 344/345 January 23, 1974

Achieved for the operating personnel: The locking sleeve bushing only needs to be without balancing a certain Immersion depth are pushed axially into the Pärbespindel, with the holding means against each other by a stop the operator is shown the correct altitude; without tiring searching you will get through slight rotation of the locking sleeve releases the further axial displacement in the same direction and by turning again slightly and then letting go of the locking sleeve through the tensioned position achieved by the return force mutual fixation of the holding means brought about, regardless of the Immersion depth of this second axial displacement section. In practice, the braced arrangement of the locking sleeve by means of fast, fluid movements without inevitably emotional movements Search of the stops are brought about. This itself causes fatigue for the operator then avoided if the locking sleeve can only be reached with an outstretched arm. Another relief can also be achieved by reducing the number of different movements required

will. This is because ¹ is possible, that the holding means of Färbespindel and closure shell through only one motion can be controlled by each other so that only only a small rotational movement of the closure sleeve is not necessary for the spring-force-induced stress. The invention has achieved this through a forced rotary movement of the holding shoulders, which happens while maintaining the axial direction, the hand movement of the operator. An advantageous embodiment is achieved here by the roof shape of the retaining shoulders. The top of the roof points in the direction of the front opening of the locking sleeve bushing, the individual roof-shaped retaining shoulders leaving the slots free between them. This roof shape achieves a double advantage: on the one hand, the axially directed pressure force results in rotation of the locking housing sleeve, regardless of which roof limb and in which section of this limb the pins of the Pärbespindel strike. a positively controlled introduction of the tenons into the slots, on the other hand then takes place under utilization

15 3 ^ 4/345 January 23, 1974

the spring force after slightly turning the locking sleeve sleeve on the inside of the roof legs a forced guidance in the fixed holding position in the Storage trough formed by the inside of the roof apex. Both for the passage of the peg through the slots as well as for storage in the inner roof valley are not targeted, dimension-dependent movements necessary. In order to realize these mass-independent movements in any case, i.e. to avoid that the closure housing sleeve after immersing the pin of the dye spindle unfortunately in a "such Position reached that when shifting back by the spring force, a modulation from adjacent slots takes place, the rotary movement of the locking housing sleeve limit stop after the pins have dipped into the interior of the bushing. The limit stop is such Kind that it takes place regardless of the slots into which the pegs have been driven. The rifle is rotated until a corresponding pin hits the stop; then with reverse control through the spring force ensures a tensioned holding position in each case. The angular range of the

509831/0119

2A03405

-7- 15 3 ^ 4/345 23.I.1974

Movement can be reduced to a minimum without additional components. This is in simply by means of a U-shaped stop bar possible, whose U-legs form the stop ribs; the distance between these stop ribs is dimensioned according to the number and the angular distribution of the slots. This ensures that regardless of the slots in which the pins of the dyeing spindles immerse, only a rotary movement is necessary, the angular range of which is smaller than that Angular distribution of the slots is. A cheap one The angle of the slots or the retaining shoulders is hereby a uniform quarter-circle distribution achieved. This has the advantage that a sufficient number of immersion slots to keep the positively controlled rotary movement to a minimum, on the other hand the roof sections are sufficient are stable and have a roof angle position favorable for the distribution of forces, with In addition, the stability of the storage trough and the slope slope for safe maintenance

509831/0119

-8- 15 344/345 January 23, 1974

the most favorable position are chosen. Canting is avoided in particular when using two radially opposite pins. D _v ie advantageous, closure sleeve according to the invention can even be used in known Färbespindeln whose end is provided with a thread. Here then only a cap has to be screwed on, which carries the pin. A further advantageous embodiment of the locking sleeve is possible in that the radial storage slot is designed in the form of a heart-shaped curve in the wall of a rotating sleeve mounted in the locking sleeve sleeve and the storage trough is in the region of the gusset of the heart-shaped curve. This configuration offers further advantages for the operating personnel. Reaching the holding position by fixing the holding means against one another takes place here as well by a combined plug-in rotary movement, but the rotary movement cannot be felt by the operator's hand, i.e. the hand does not have to carry out the rotary movement, since only the rotary sleeve carrying the stops rotates inevitably , the locking sleeve sleeve and thus the handle, however, remain radially immobile. To reach the tensioned holding position

509831/0119

-9- 15 344/345 January 23, 1974

For the operator, all that is practically necessary is the axial movement for pushing in the locking sleeve. Here, too, there is no need to feel the holding position by feeling. The axial pushing-in movement of the locking sleeve is limited in its end position by the upper area of the heart-shaped curve; upon release of the closing sleeve, the spindle pins föderkraftunter- _# superimposed supports in the storage recess in the region of the gusset Heart a. An optimal configuration is achieved here by a forced control for bringing about both the closed and the open position. The lower edge of the holding shoulder, which is anchored to the apex of the heart, steers the peg into the slot guide on this side of the central axis of the heart, the resulting storage in the storage depression of the central region of the heart being such that the upper edge of the central curve of the heart lies offset next to the central axis , ie, the embedded pin is covered on the top by the gusset edge, which points in the direction of discharge. As a result, when the locking sleeve is pressed in to achieve the holding position, there is a forced guidance in this side of the

609831/0119

-10- 15 344/345 January 23, 1974

Central axis lying heart curve slot guide and when the button is pressed again to achieve the open position, the pin is driven out of the beyond the central axis of the heart. In conjunction with a funnel-shaped Design of the mouth end of the storage slot is optimally easy to use achieved. Both the forces to be expended and the necessary movements are to be brought about hold and open position the same. The loosened closure sleeve only needs to be placed on the dye spindle to be put on and pushed in in the axial direction, with this axial movement alone Holding position is achieved. To cancel the holding position again, the same movement is necessary, namely simple axial pushing in of the locking sleeve. This optimal solution brings for the operator not only a considerable time saving, but also the forces are saved in a favorable manner. This is in terms of production technology and use nor to mention the advantage that the support to the

509831/0119

-11- 15 344/345 January 23, 1974

Intermediate shoulders allow a tilt-free and easy rotation, which by intermediate layer of discs or other pivot bearings with low frictional forces can still be improved. Also at the embodiment described above is a Design possible, the control of the pin in the storage troughs without rotating movement of the locking sleeve made possible by the hand of the operator. Here, too, the holding position is practically only achieved by axially pressing in the locking sleeve. This advantage can be due to the slightest structural Measures are achieved; the roof-shaped retaining shoulders only need to be designed so that the one roof leg is formed longer, in such a way that it extends beyond the area of the roof leg the adjacent retaining shoulder protrudes. The individual retaining shoulders are designed so that the longer one Roof leg is always opposite the shorter roof leg of the adjacent retaining shoulder. When pushed in axially the locking sleeve is the pin of the dye spindle by this measure not only through the slots brought through forced control over the height range of the retaining shoulders, but beyond that even in

509831/0119

-12- 15 3 ^ 4/345 January 23, 1974

overlapping position. When the locking sleeve is released. consequently, the pegs lie down without additional twisting the closing sleeve into the storage troughs by the operator with the aid of spring force. The longer roof legs of the retaining shoulders can also have advantageous details: namely at the free end a downward angled end stop to limit the rotary movement, and a length alignment, which extends beyond the area of the storage trough of the adjacent holding shoulder, whereby the advantage is achieved that when the opening position is brought about, the vertical immersion depth is limited by a stop in order to avoid unnecessarily large axial indentation paths.

The subject matter of the invention is based on three exemplary embodiments illustrated in more detail below. Show it:

Pig. 10 shows an enlarged illustration of the rotary sleeve in longitudinal section in the region of the heart-shaped curve.

The dyeing spindle 1 has a closure sleeve 2 on the top and a thread winding carrier 3

The task of the closure sleeve 2 is to support the yarn winding carrier with the help of the Pärbespindel 1 to brace against a fixedly arranged on the Pärbespindel base plate 4. the Base plate 4 is plate-shaped and has a centering elevation 4 '. With the appropriate design several thread winding carriers can be provided on one pair of spindle. The twine winder are provided with passage openings 3 ', for example to penetrate the parb liquor when coloring the Yarn.

The upper-side locking sleeve 2 consists of a handle 5 and a handle downward on it in the vertical direction extending adjoining locking sleeve sleeve 6, at its free end a stop bead 7 for one

509831/01 19

-15- 15 344/345 January 23, 1974

forms a pressure plate 8 displaceably arranged on the closure sleeve sleeve 6, which pressure plate 8 in the direction of the bead 7 of a likewise on the .Verschleußhülsen-bushing β between handle 5 and plate recess 8 'of the pressure plate 8 arranged Compression spring 9 is under spring load.

The bottom of the pressure plate 8 rests against the upper edge of the thread winding carrier, 3 · When the locking sleeve sleeve is pushed in 6 in the axial direction of the arrow χ, the spring forces of the compression springs 9 press the pressure plate 8 against the thread winding carrier so that it is clamped between the stationary plate 4 and the pressure plate. To the Maintaining this tense position must be the Locking sleeve sleeve 6 can be fixed in this position. This is done in connection with the upper, cylindrical section 1 'of the dyeing spindle 1, from which section 1' radially opposite pins 10, 11 go out.

To achieve a firm tension, the free end of the locking sleeve bushing 6, which forms the bead 7, is pressed in the direction of the arrow χ beyond the area of the pins 10, 11 into the interior of the yarn package carrier 3 are, the pins 10, 11 then in the

-16- 15 344/345 January 23, 1974

Immerse the interior of the sleeve 6,

The inner edge 12 of the free end of the bushing carries roof-shaped retaining shoulders 13 ₃ which release braids 14 for the passage of the pin 10 _s 11 between them.

The roof-shaped _{retaining shoulders are designed 3} so that their roof apex 13 'points in the direction of the front opening 15 of the locking sleeve socket.

When the closure sleeve 2 is pushed in from the open position into the thread winding carrier, this occurs in any case one upwardly inclined roof leg 16 against each pin IO or 11.

This results in a positively controlled ₃ radial displacement of the locking sleeve sleeve 6 until the slots 14 are above the pins 10, 11 ₃ so that these pins can escape through the slots into the interior 17 or that the locking sleeve sleeve S catches over the Pin 10, 11 can be shifted further in the direction of arrow χ.

509831/0119

-17- 15 344/345 January 23, 1974

The locking sleeve must then be turned until that the pins 10, 11 pass over the surface area of the inner sides of the legs of the holding shoulders. When the handle 5 is released, the bush 6 is displaced by the restoring force of the spring 9 counter to the direction of the arrow x, the pegs 10, 11 each being formed in one formed by the inner roof valleys 18 Insert storage tray M.

The tensioned holding position is thus fixed.

In order to ensure that when you let go of "the handle to move the sleeve backwards 6. against the direction of the arrow χ the pins 10, 11 are in each case above the area of the retaining shoulders is on the inside of the housing vertically directed stop rail 19 is provided, the U-legs of which form stop ribs 20, 21.

With the quarter circle division illustrated in the drawing of the stops, the rotary movement is independent of the slots 14 through which the pegs have passed through, so limited that a storage of the pin in the storage troughs M in takes place in each case.

• Figures 6 and 7 show a second embodiment for the design of the roof-shaped retaining shoulders. These Retaining shoulders 22 are aligned in the same way with regard to their roof apex. those described above Retaining shoulders 13, however, the roof legs 23, 24 have different lengths. The roof leg 24 of each retaining shoulder 22 is so long that it extends beyond the area of the storage trough M of the adjacent retaining shoulder 22 protrudes. Each long roof limb 24 - each holding shoulder 22 is a shorter roof limb 23 opposite the adjacent retaining shoulder. This creates a forced control up to the range of Exnlagerungsmulde achieved, as well as a limit stop in the vertical direction to bring about the Open position.

The free ends of the roof legs 24 can also act as a rotary stop for bringing about the holding position if necessary, be provided with downwardly directed stop lugs.

In order to be able to use the closure sleeve according to the invention also with known spindles 25 which are connected to are provided with a thread 26 at their free end on the upper side, a cap 27 is placed on the thread end screwed on, which carries the pin 28, -29. the The cap can be fixed in a rotationally fixed manner by bracing it with a lock nut 30.

A third exemplary embodiment is shown in FIGS. 8 to 10. The locking sleeve bushing is in two parts here formed, the upper part 3I on the underside a folded back Has edge bead 32, which leaves a central passage opening free and with the upper edge of the lower part 33s that also has a folded collar 34 possesses, which also leaves a central passage opening free, is firmly connected.

In the lower part 33, a rotating sleeve 35 is rotatably mounted, having a top-side bearing boss 35 ¹ has ₃ which projects into the central passage opening of the collar 34th The rotary sleeve 35 is protected from falling out of the lower part by an angled lower-side retaining edge 36 of the lower part 33 engaging below the lower end of the rotary sleeve 35. At the points of separation between the slewing sleeve 35

509831/0119

-20- 15 344/345 January 23, 1974

and the lower part 33 pivot bearing disks 37 are provided to reduce rotational friction.

The rotary sleeve 35 has a central, axially directed channel 38, which for the passage of the cylindrical spindle end 1 'is provided.

To fix the clamped holding position, the inner walls of the sleeve 35 form two radially opposite one another Storage troughs M for the pins 10, 11 of the Pärbespindel. Those formed by retaining shoulders 41 ' Storage troughs M lie in the gusset area Z of a heart-shaped curve K, which is used to control the Tenon is used.

The heart-shaped curves lie radially opposite one another on the inner wall of the sleeve 35, with them on the underside have a funnel-shaped mouth end 39 which continues into the storage slot 40. The storage slot 40 sits on the central axis y-y of the asymmetrically designed heart-shaped curve K.

The lower edge 41 of the storage trough M is the storage slot 40 opposite, in such a way that a pin 10, 11 positively controlled in the inlet direction the one on this side

509831/0119

-21- 15 344/345 January 23, 1974

the axis y-y lying cardiac canal 42 passes through. The pin 10, 11 is then positively controlled in the Brought to a stop position in the storage trough M. 'The gusset edges 43 of the heart-shaped curves are aligned so that they lie over the pegs 10, 11 and in the direction of the heart canal 42 are offset from the y-y axis.

To bring about the open position · the locking sleeve is again in the direction of arrow χ in the Yarn winding carrier 3 is pressed in, the pin 10, 11 striking against the gusset edge 43 and positively guided through the cardiac canal 44 on the other side of the y-y axis, which leads to the apex 45 of the heart, this in a figurative sense, since the pins remain stationary and the sleeve is displaced.

This is both to achieve the holding position and to bring about the open position same movement of the operator is necessary, namely only axial pressing in of the locking sleeve in the thread spool carrier. The necessary control of the sleeve 35 takes place through its rotatability in Connection with the heart-shaped control cams K.
