Definitions

  • the invention relates to a thread delivery device of the type defined in the preamble of claim 1.
  • the delivery drums have a continuously closed support surface and therefore also continuously closed inlet, storage and possibly outlet sections for the thread.
  • Such delivery devices are used in a continuously driven delivery drum either for positive, slip-free or slip-free thread delivery or for non-positive, slip-promoting friction promotion and work satisfactorily with a large number of thread types.
  • filaments are frequently torn out of the thread parts leaving the delivery drum or also from individual thread turns located in the storage section. Apart from this, the high surface adhesion sometimes leads to difficulties, at least for some desired functions of the delivery device.
  • thread delivery devices of another known type (DE-OS 32 26 373, DE-PS's 34 37 252 and 35 06 490), which are only rod-shaped, in particular in the storage sections Have support elements for the threads.
  • Such delivery devices have so far mainly been used for applications which the delivery drums are driven intermittently in the start / stop mode, since the rod-shaped support elements achieve a reduction in the mass of the delivery drums, which is desirable for a quick response when accelerating or braking.
  • thread delivery devices are also not universally applicable, because the threads often require friction conditions that can only be ensured by delivery drums with closed outer surfaces.
  • delivery devices with delivery drums are desired which, depending on the thread material, can either be provided with closed sections or with storage sections formed by rod-shaped support elements.
  • Such delivery devices are not yet known in connection with knitting machines. It would be conceivable to provide devices designed in the form of push-on sleeves which can be interchangeably attached to the delivery rollers and have closed surfaces with different coefficients of friction and / or diameters in order to take account of the different properties of the threads (CH-PS 503 138) .
  • An analogous transfer of this principle to delivery devices, the delivery drums of which are optionally provided with closed or circumferential surfaces formed by rod-shaped support elements, is not readily possible for geometric reasons.
  • the invention has for its object to provide the thread delivery device of the type mentioned in such a way that it can be operated either with the usual closed or with a storage section formed by rod-shaped support elements or with storage sections, which can be operated in dependence on low design and cost rod-shaped support elements selected from the thread material are formed with different properties and / or arrangements.
  • the changeover from one type of drum to the other should be carried out in a few simple steps and with structurally simple means.
  • a rod cage can be dismantled for cleaning, repair or replacement simply by stripping off its inlet element and, if necessary, the holder. It is correspondingly easy to place a rod cage on the rotating body. When using simple clamping or snap mechanisms, no tools are even required. Only a few and very easy to manufacture components are required to produce the rod cage. The downtime of the knitting machine for cleaning, repair or replacement work is practically limited to the short assembly and disassembly times. It is also easily possible to retrofit existing yarn delivery devices with the delivery cages according to the invention to the rod cages according to the invention by providing them with appropriately adapted inlet elements and holders. If the inlet element is e.g.
  • the thread inlet can take place along a substantially closed surface, while the thread is only guided on the rod-shaped support elements within the storage area.
  • the thread delivery device shown in FIG. 1 has a carrier 1 which is detachably fastened at one end to a mounting rail 2 of a knitting machine.
  • a rotary body 3 is arranged in the form of a conventional delivery drum which is rotatable about an axis of rotation 4 and for this purpose is fixedly connected to a shaft 5 which is rotatably mounted in the carrier 1.
  • two pulleys 6 are rotatably mounted, which are optionally coupled to a coupling member 7 can.
  • the coupling member 7 consists, for example, of a coupling disc arranged between the two pulleys 6, axially displaceable but non-rotatably on the shaft 5.
  • the pulleys are driven by a drive, not shown, by means of belts 8 at different speeds.
  • a thread brake 9 and a thread eyelet 10 arranged above it are fastened to the end of the carrier 1.
  • a thread inlet guiding element 11 arranged between the thread brake 9 and the delivery drum 3, e.g. an eyelet is provided, while on the diametrically opposite side of the delivery drum 3 of the delivery drum 3 two further, attached to the underside of the carrier 1 thread outlet guide elements 12 and 13 are provided, which can also consist of open or closed eyelets.
  • a thread 14 is guided from a supply spool, not shown, through the thread eyelet 10, the thread brake 9 and the guide element 11 obliquely from above and essentially tangentially onto the thread support surface of the delivery drum, wound on it in at least one, preferably several turns and finally essentially tangentially and fed through the two guide elements 12 and 13 of the knitting point, not shown, to a knitting machine.
  • Sensors 15 and 16, which are also attached to the carrier 1, can be used in the usual way to monitor the thread 14.
  • Thread delivery devices with the structure shown in FIG. 1 are basically known (DE-PS 27 43 749).
  • the different sections of the delivery drum itself can be any be designed, although certain shapes have proven particularly advantageous for the inlet section 19 and the second end section 21 (DE-PS'en 35 01 944 and 35 16 891).
  • a rod cage 23 is coaxially attached to the rotating body 3 consisting of the delivery drum, which has an annular inlet element 24 and an annular holder 25, the inlet element 24 coaxial on the first end section 18 and the holder 25 on the second end portion 21 of the delivery drum comes to rest.
  • rod-shaped, e.g. Support elements 26 made of steel wire or spring wire are arranged, which form a storage element of the rod cage 23, run essentially parallel to the axis of rotation 4 and are distributed along the circumferential surface of an imaginary cylinder or cone coaxial to the axis of rotation (FIG. 3), which is in the direction of the end section 21 is slightly tapered.
  • the support elements 26 preferably have the same angular distances from one another, although at least slightly different angular distances are also conceivable.
  • the support elements 26 are fastened to the inlet element 24 and the holder 25, for example, in that holes or bores are formed in their mutually facing ring surfaces into which the upper (first) and lower (second) ends of the support elements 26 in FIG. 2 inserted with a press fit and additionally glued in if necessary.
  • the inlet element 24 has an approximately U-shaped, circumferential holding section 27, which is provided with an essentially cylindrical inner surface, the diameter of which corresponds to the outer diameter of the first end section 18 of the rotary body 3.
  • An upper leg 28 of the holding section 27 in FIG. 4 rests on the upper side of the first end section 18, while a lower leg 29 of the holding section 27 in FIG. 5 can additionally bear against a conically tapering part 30 on the underside of the first end section 18 .
  • the holding section 27 In order to make it easy to attach and detach the holding section 27, it has a number of radial slots or grooves 31 in its leg 28 (FIGS. 2, 4 and 5), so that a number of sectors are created which are pushed on or pulled off of the holding section 27 are spread radially outwards by the first end section 18 and then spring back radially inwards again. As a result, the holding section 27 is fastened to the rotary body 3 in the manner of a snap connection, so that no tool is required to attach or remove it.
  • the entire inlet element 24 is preferably made of a sufficiently flexible or thin material so that the holding section 27 can also be securely fastened to the first end section 18 without a tool due to its elastic properties.
  • the holder 25 consists of a ring which, in its upper end face in FIG. has rectangular, circumferential receiving shoulder 32 for the lower part of the second end portion 21.
  • the arrangement is preferably such that the end section 21 is held with a press fit between the walls of the receiving shoulder 32 and the holder 25 is thereby fixed axially and radially on the end section 21.
  • the second ends of the support elements 26 are thus also radially centered with respect to the axis of rotation 4. No tools are required to assemble or disassemble the bracket.
  • the support elements 26 are straight throughout.
  • the inlet element 24 has on its outside and outside of the imaginary cylinder or cone formed by the support elements 26, a frustoconical, in FIGS. 4 and 5 from top to bottom and inside, ie tapering towards the axis of rotation 4, closed circumferential inlet surface 33 for the thread 14, which is expediently designed like the corresponding surfaces of the preferred known delivery drums (DE-PS 35 01 944), although other shapes may also be expedient in connection with the rod-shaped support elements.
  • the support surface 33 can have the same cone angle throughout.
  • slot-shaped recesses 34 being machined into the inlet element 24 at the transition between the inlet surface 33 and the support elements 26 are that affect the surface of the thread 14 only slightly.
  • the recesses 34 each create a cavity surrounding the associated support element 26 in the area of the transitions to the storage section, through which any contamination, fluff or the like can migrate radially to the rear, ie into a cavity 35 between the support elements 26 and the casing of the rotating body 3 .
  • the recesses 34 allow a smooth transition of the thread 14 from the inlet surface to the support elements 26 without forming a noticeable step.
  • the closed inlet surface 33 offers the advantage that the thread 14 is guided in a punctiform manner in the inlet region and not, as subsequently in the storage element, and is thereby prevented from slipping prematurely onto the storage element. Otherwise, the inlet surface 33 can be extended outwards and in FIG. 5 at the top by an extension 36 which serves as a cover and prevents unwanted sliding of loose thread layers onto the top of the rod cage or the rotating body 3.
  • the recesses 34.38 have advantages in manufacturing. Since the burrs which are unavoidable during the production of the bores for the support elements 26 do not come into contact with the thread, their post-processing is not necessary. In addition, the drills used cannot run when tapping.
  • the rod cage 23 consists of a unit prefabricated by the manufacturer, the inlet element 24 and the holder 25 of which, as described above, are placed on the delivery drum which is also operable without the rod cage 23 and is attached to it. 1 to 4, the delivery drum is fastened at its upper end to the drive shaft 5, in this case the rod cage 23 is pulled onto the delivery drum from below.
  • the first end section 18 has a larger outer diameter than the second end section 21 and the leg 28 of the holding section 27 can be widened somewhat outwards, if required, even when slipped over the lower end section 21 in FIG. 4.
  • the inlet element 24 and the holder 25 are made of flexible plastics, for example by injection molding, so that the entire rod cage 23 is flexible in itself and therefore when plugged on is sufficiently compliant on the delivery drum.
  • the support elements 26 are preferably made of a wear-resistant material or material made wear-resistant by coating. The same applies at least to the inlet surface 33.
  • a holder 41 is provided in the form of a circular disk, which is suitable for pot-shaped rotating bodies with an inner recess 42 and is preferably pressed into it with a sliding fit, but can also be snapped in by means of a snap connection or the like.
  • the lower second ends of the rectilinear support elements 26 are supported at the outer end of the second end section 21 of the rotary body 3 and are provided with extensions which initially have an outwardly flared section 43 which is designed according to the outlet surface 37 according to FIG. 4, then by approx Are bent back 180 ° and finally merge into a holder section 44 which is fastened in the holder 41 and is preferably additionally supported at 45 on the inner surface of the lower edge of the delivery drum in FIG.
  • the outlet sections 43 prevent loose thread turns from falling off and the formation of fiber rings, while the holder sections 44 additionally center the support elements 26 radially.
  • FIG. 7 differs from that according to FIGS. 1 to 5 in that the recesses 34 are missing, whereas in comparison to FIG. 6 there are holding sections 46 which are not additionally located on the rotating body 3 support, but are only held in a holder 47 inserted into the recess 42 in the form of a circular disk which is neither centered nor fixed even in the recess 42.
  • the holder 25, 41 or 47 is missing.
  • the support elements 26, which are designed similarly to FIG. 6, are provided with holder sections 48 which are supported on the inner edge of the rotating body 3 at 49 and e.g. Snap into radial notches 50, which are formed on the inside of the lower edge of the rotary body 3 in FIG. 8, in the manner of a snap connection.
  • the rod cage is assembled by first inserting the inlet element 24 onto the first end section 18 of the delivery drum and then threading the second ends of the elastically bendable support elements 26 into the notches 50.
  • FIG. 9 differs from that according to FIG. 7 essentially by the shape of a holder 51, which is designed as a circular disc with a conically extending lateral surface 52, which bears against a correspondingly conical contact surface on the inside of the lower edge of the rotating body 3 or is held by a catch and receives mounting portions 53 which are formed on the extensions of the support element 26.
  • the recesses 34 are provided.
  • the disk-shaped brackets 25, 41, 47 and 51 can also be replaced by ring disks or ring segments.
  • FIG. 10 shows an embodiment in which, similar to FIG. 8, the holder 25, 41, 47 or 51 is missing. Instead, the rotary body 3 has a wall 54, which delimits a recess 58 upwards, with a circumferential groove 55, short radial slots or bores into which the free ends of mounting sections 56 of the support elements 26 protrude. These support sections 56 are also bent so that they can be supported with central areas according to FIGS. 6 and 8 on the inside of the lower edges of the rotating body 3, as shown at 57.
  • Fig. 11 shows an embodiment in which the rotating body 3 additionally with a coaxial, protruding into its inner cavity, in the manner of a polygon, e.g. Hexagon, trained approach 59 is provided.
  • the holder 25 of the rod cage 23 which can be plugged onto the rotating body 3 is connected to the inlet element 24 by a closed jacket 60 which surrounds the rotating body 3, for example by gluing or ultrasonic welding.
  • the holder 25 has a tubular extension 61 projecting into the cavity of the rotary body 3, which is provided with an internal cross section corresponding to the outer cross section of the extension 59 and, when the rod cage 23 is plugged onto the rotary body 3, is pushed onto its extension 59 and rotatably fixed with it is coupled.
  • the rod cages can be provided with different support elements with regard to their number, diameter, length, material and shape.
  • the diameter of the imaginary cylinder or cone formed by the support elements 26 can itself be selected as desired. This diameter should, on the one hand, be so large that the thread 14 only lies on the support elements 26, but not between them, also on the outer surface of the rotating body 3, and on the other hand be sufficiently small so that the maximum diameter of the entire rod cage 23 remains small and no change in the position of the guide elements 11, 12 and 13 is required.
  • the inlet surface 33 (FIG. 4) for the thread 14 is preferably arranged at such a location on the inlet element 24 that the position and orientation of the guide elements 11, 12 and 13 can remain unchanged regardless of whether the delivery drum is alone or with attached rod cage 23 is used.
  • the invention is also not limited to the fact that the rotating body 3 is a thread delivery drum that is functional in itself. Such an embodiment is preferred, however, at least for those cases in which a thread delivery device having a delivery drum with a closed surface is already in operation and is to be supplemented by the rod cages 23 described. In other cases, it would be conceivable, for example, to provide only the shaft 5 as a rotating body, to design the inlet section 24 of the rod cage 23 essentially as a disk, and to fasten the rod cage 23 to the shaft in an easily replaceable manner by means of this disk.
  • the shaft 5 and the disk could be equipped with corresponding, e.g.
  • the rotary body could consist of any support body which is used only for mounting the rod cage 23 and in turn is fastened to the shaft 5, which would have the advantage that it would be very inexpensive to produce, deviating from FIGS. 1 to 11, since it itself is not suitable for thread guidance , should only have surfaces that can be produced by precision machining.
  • the rod cages 23 could be assigned, if required, delivery drums which, like the rod cages, can be attached to the respective rotating body by being plugged on, snapped on or clamped, and which have properties adapted to selected thread types or applications, in particular thread contact surfaces. This would allow the knitter to move his knitting machine in a few simple steps, i.e. to adapt to the prevailing circumstances in individual cases without cumbersome manipulations or adjustment work and without exchanging the entire thread delivery device.
  • the inventive design of the rod cage 23 enables extremely simple and inexpensive series production.
  • the inlet elements 24 and brackets 25 are produced, for example, from injection molded plastic parts, the support elements 26 being inserted into the injection mold and therefore being cast in at the same time.
  • the diameter of the rod cage 23 in the region of the storage element is 53 mm when eight to eighteen, preferably twelve rod-shaped support elements 26 are used.
  • These support elements 26 are arranged slightly conically to the axis of rotation 4, so that a around in the area of the thread outlet up to 0.80 mm, preferably 0.60 mm smaller diameter than in the area of the thread inlet with a distance of these two areas of, for example 16.5 mm results. This distance can also be larger or smaller and is preferably dimensioned such that the position of the guide elements 11, 12 and 13 can remain unchanged.
  • the diameter of the support elements 26 is e.g. 0.30 to 1.5 mm, preferably 0.45 mm.
  • the support element 26 consist of a preferably stainless steel wire (spring steel wire).
  • the inlet surface 33 has a cone angle of approximately 30 ° to the axis of rotation 4.
  • the inlet elements 24 and brackets 25 are preferably made of a wear-resistant material, in particular plastic, which is made wear-resistant at least in the area of the thread support by coating.
