Description

Textile yarn creel

What the present invention relates to is to be used for supporting many yarn tubes and yarn to be fed the textile yarn creel that goes on knitting machine or the similar Weaving device by the there.

The yarn creel of various different structure and special purpose has been commonly people and has been familiar with, and generally adopt in textile industry storage and yarn feeding to the weaving loom of various types, usually, general yarn creel consists essentially of a vertical falsework of upright floor type, stretch out many yarn tube supporting members from this falsework, so that support many yarn tubes and yarn unwinding from it.Yarn tube supporting member can adopt taper, tubular, tubular or similar form, on it around a jointless yarn.Yarn tube supporting member is normally by level of being arranged in and vertical outwardly directed yarn tube supporting single shaft of the falsework from upright or bar, so that simplify the device of the similar ledge of the many yarn tube supporting members that are supported.

The textile machinery of go-go yarn treatment or fiber production is applicable to the yarn that uses the hundreds of kind different simultaneously.In addition, because the competitiveness of it and foreign made commodity is cheaply wanted to do one's utmost to keep or recovered in the textile industry of the U.S., made the ground degree of utilization that many effort go to improve production operation.The result, in recent years the structure of textile machinery be to reduce total machine dimensions and or increase the ability of the use yarn of machine, so that develop to the direction of increasing the yield per unit area, give one example, present circular knitter, in fact adopt be with 15-20 before the same size of circular knitter made, still, feeding and knitting ability meet or exceed the twice of the number of threads of old machine.

Yet, when such improvement of making machine context has improved capacity rating, new problem has appearred, and these problems can be eliminated the part saving that has realized conversely again.At first,, then need the corresponding place of increasing supply and storing yarn if when increasing common machines and using the ability of yarn, for example, yarn creel.The yarn creel of common form described above is made fixing size and fixing yarn tube storage capability.Therefore, when needs increase the yarn tube, must increase the additional needed place of yarn tube, otherwise, if any yarn creel that uses during less than its designed productive capacity, has then been wasted the place, like this, yarn tube storage problem is to solve by such fact, be that prevailing creel can be stored double-type yarn tube, the feeding that the yarn tube is used to begin, and another yarn tube and first yarn tube are serially connected, when using up fully, as the usefulness of its spare part with first reel for yarn of box lunch.

Correspondingly increased the output of velveteen and similar fiber product and refuse along with the increase of yarn utilization and unit area fiber product.Those of ordinary skill has realized that the normal operation that can limit or stop machine fully of accumulating of velveteen on the machine, causes to shut down and produce substandard products and other many problems.In addition, the velveteen that flies upward has also caused the harm to workers ' health.Therefore, along with utilizing more high efficiency common textile machinery, necessary periodic cleaning machine, and place that occupies and purification ambient air accumulate so that reduce velveteen.

The annular textile yarn creel that the purpose of this invention is to provide a compactness is used in particular for increasing or reduce the yarn silos capacity of yarn creel selectively and the occupation of land space that do not increase whole yarn creel, and in addition, yarn creel comprises a special device that prevents that velveteen from piling up.

In brief, textile yarn creel of the present invention comprises a toroidal frame device and the many tube of yarn longitudinally bearing sets, these bearing sets axially are installed on the toroidal frame device selectively on the circumferential position and are spaced from each other, and each yarn tube bearing set has many yarn tube supporting members.After support unit was installed, these yarn tube supporting members were radially inside along this toroidal frame device.In use, can select the yarn tube bearing set of quantity to be installed on the toroidal frame on the selectable position, and spaced apart in the circumferential directionly can select the yarn tube of quantity with supporting, yarn is promptly from these yarn tubes feedings.The feed carrier axial centre of toroidal frame device ground arranges, with place from the yarn barrel dliameter to the yarn and guiding yarn to a Weaving device that links of unwinding upcountry, as circular knitter.By this way, yarn creel is applicable to can select the yarn tube of quantity with the bearing set supporting that can select quantity in a same compact zone that is limited by the toroidal frame device.

Another characteristic of the present invention is, removes the special device of velveteen from yarn creel, comprises a compressed air source and an air injection tube substantially, and jet pipe roughly is arranged on the toroidal frame device to this axial centre, and is connected with compressed air source.Be provided with the injection hole of many spaces on the position of in jet pipe, selecting, radially outward to spray pressurized air towards yarn tube bearing set and feed carrier.Electrical motor or similar means are used for making jet pipe to rotate.Timer device is the control motor periodically, make jet pipe rotate a whole circle at least and control compressed air source simultaneously and make pressurized air enter jet pipe, remove and prevent the velveteen that on yarn creel, accumulates so that when this jet pipe rotates, outwards spray by the whole circumference of injection hole.Remove assembly as an alternative velveteen, fan can be installed on the toroidal frame device, blow surrounding air, remove velveteen and prevent the velveteen accumulation.

In most preferred embodiment, the toroidal frame device is made of two toroidal frames, and each toroidal frame comprises concentric interior ring and outer shroud.Each yarn tube bearing set has two identical multi-support bearing pin groups that are spaced laterally apart a segment distance at this yarn tube bearing set, each bearing pin of these two groups of bearing pins correspondingly is spaced along this yarn tube bearing set, and by stretch out there, when being contained on the yarn creel with box lunch, bearing pin inwardly extends the side to its footpath.By this way, two groups of bearing pins are suitable for supporting first group of yarn tube that is feeding on the yarn tube of yarn and use as spare part second group respectively when the yarn tube on first group uses up.

In the embodiment of a yarn tube bearing set, each device comprises a vertical part, and this vertical part has two multi-support arm groups, and this arm is contained in the relative both sides of vertical part respectively.Each yarn tube supporting arm has one by the yarn tube supporting shaft that stretches out on it, and rotates between control position and off-position.On control position, bearing pin is arranged to outwards leave a spacer segment with the respective side of vertical part, when vertical part is installed on the toroidal frame, so that bearing pin is extended to toroidal frame device internal diameter direction, yarn tube orientation by pin bearing makes it extend to yarn guiding device, so that extract yarn out.On off-position, arm and bearing pin leave control position fully, so that can take off the yarn tube supporting that uses up and by another yarn tube supporting member of packing into of shared place on control position by arm and bearing pin.

In another embodiment of yarn tube bearing set, each device comprises a pair of vertical part, so that being contained on the toroidal frame device side by side independently can become mutually arbitrarily at interval at circumferencial direction, each vertical part comprises one group of yarn tube supporting shaft.

With reference now to accompanying drawing,, indicates a embodiment according to textile yarn creel of the present invention with 10 and by Fig. 1-3 beginning.For illustrative purposes, shown yarn creel 10 has the circular knitter (not shown) of 48 yarn feeding devices to install for yarn to is provided, and therefore, needs to supply with 48 one threads.To explain more fully that as the back yarn creel is applicable to that 48 pairs of supportings are used to bring into use and replace the yarn tubes that use, in general use, yarn creel 10 is vertically fixed on the knitting workshop and the next door of the circular knitter of connection with it.

Usually, yarn creel 10 comprises: an annular fitting work frame, represent with 12; The many tube of yarn longitudinally support units are represented with 14, are contained on the ring device of this falsework, in its axial extension parallel to each other; With many yarn guide parts, represent with 16 usually, be contained in the less device of the diameter of falsework 12 axially parallels on, and concentric with yarn tube support unit 14.As will illustrating fully later on, yarn tube support unit 14 is supporting the yarn tube 18 at above-mentioned many diameter centers towards falsework 12, so that from it to diameter center unwinding yarn.The yarn that 16 acceptance of yarn guide parts come from yarn tube 18, and by upwards guiding yarn to pass through the center axial region of yarn creel 10 there, then upwards be fed on the knitting machine.

Yarn creel 10 of the present invention mainly is for suitable supporting and the feeding spun yarn of using, i.e. the yarn of making by twisted chopped fiber, and yarn is wrapped on the conical bearing spare, so that yarn is got around towards the smaller diameter end direction.But those of ordinary skill is easy to recognize that yarn creel of the present invention might be applicable to that supporting and feeding are wrapped in any type of yarn on any various supporting member or the parts.Therefore, the invention is not restricted to use spun yarn, also be not limited to use conical bearing yarn tube.Therefore be to want the yarn or the long filament textile yarn that comprise that any type of staple is spun into as term used herein " yarn ", no matter that synthesize or natural fiber, and any other lamination coating.Also refer to the yarn tube that is wound with yarn on taper, tubular, tubular or the similar thing of comprising at any kind of as term " yarn tube " as used herein.

Annular fitting work frame 12 comprises a pair of relative toroidal frame 20, and each toroidal frame has outer,

interior ring

22,24, and is on the circle spacing that equates that it is fixing with one heart rigidly with three supports 26 of radially extending.Outward, interior ring the 22, the 24th, surround the annular of desired diameter by the laths of metal of designated length, the end solder together is made.Support 26 and make, and be welded on the position of outer,

interior ring

22,24 desired interrelations by identical metal sheet billot.

As Fig. 3 be clear that, each yarn tube support unit 14 is made by long straight round metal tube 28.There is a translot 30 pipe 28 end, promptly at circumferencial direction, is the side at circumference here.Translot 30 slightly than the width of the laths of metal of making toroidal frame 20 more greatly, is packed outer shroud in the groove 30 into so that be suitable in axial length.In this way, the pipe 28 of each yarn tube support unit 14 is suitable at random being contained on the outer shroud 22 of toroidal frame or takes off from it, and also is suitable for can at random sliding on the circumference of outer shroud 22 and fixing it.Be the clamping element 32 that each groove 30 is prepared, it is narrower and have a plate longer slightly than the axial dimension of each groove 30 than pipe 28 diameters to generally include width.Each clamping element 32 is suitable for being inserted in the groove 30.Its length direction extends axially along corresponding pipe 28, is configured in the centre of the inside face of outer shroud 22 that is loaded in the groove 30 and the pipe 28 of making groove 30.A tapped bore 34 passes the center of each clamping element 32 length direction, bolt 36 is housed in it, this bolt can rotate with outer shroud 22 and contact, enter in the groove 30 fully and the two ends that promote the length direction of clamping element 32 are connected with inside face near the pipe 28 of groove 30 length directions to promote it, so that support and make outer shroud 22 and manage 28 and be clamped together rigidly.

Clearly, groove 30 makes on the outer shroud 22 of falsework 20 can install yarn tube support unit 14, and the groove face that has of each support unit 14 radially inwardly or radially outwardly faces toward toroidal frame 20.Best, the groove 30 of support unit 14 along diametric(al) to the outside to falsework, so that than being easier to load onto clamping element 32.

Welding of many yarn tube supporting shaft 38 usefulness or other mode are fixed on each pipe 28, so that extended radially out by a side opposite with groove 30 on the pipe 28.In addition, when the supporting shaft 38 on the pipe 28 was contained on the falsework 20, an end was inclined upwardly a little.Therefore, supporting shaft 38 will inwardly and a little protrude upward along falsework 20 diametric(al)s, so that accept and supporting yarn tube 18.Best, each pipe is adorned 8 supporting shafts 38 on 28, because the yarn feeding number of many common annular knitting machines is 8 multiple.

Each yarn guide parts 16 has the structure that can be complementary with yarn tube support unit 14, and in Fig. 3, see too clearly, each yarn guide parts 16 is shaped on groove 42 by every end of respective length round steel pipe 40 with the clamping element 44 relevant with groove 42 be housed form, so that allow each pipe assembly parts can with above-mentioned about the identical mode of yarn tube support unit 14, on the interior ring of falsework 20, move and on its circumference, slide.Pipe 28 as yarn tube support unit 14, the pipe 40 of yarn guide parts 16, when encircling on 24 in being contained in, preferably its groove 42 is towards foreign side radially, so that above installing to easily, each pipe 40 has many holes 46, and preferably to manage the quantity of the supporting shaft 38 on 28 identical for each of its quantity and yarn tube support unit 14, and hole 46 is by managing 40 diametric(al) and being that benchmark is made with the circumference range of managing 40 groove 42.A yarn guide rings porcelain or plastics are contained in each hole of fluting one side of corresponding pipe 40, so that when being contained on the hole, radially outward towards interior ring 24.A flexible plastic pipe 50 is contained in the opposite side radially inner side of the respective tube 40 in hole 46, and has enough length, so that from extending upward here, by the axial centre zone of falsework 12, get on upward to adjacent knitting machine.

Preferably on underframe 20,3 or more foot-supporting frame 45 equally spaced are installed so that falsework 12, yarn tube support unit 14 and yarn guide parts 16 are supported on the floor that is elevated to the placement yarn creel a little.Each foot-supporting frame 45 is attached thereto the clamping element 51 that connects by the short pipe 47 that is shaped on groove 49 thereon and one and constitutes, and this clamping element installs on the pipe 47, and is fixed on the outer shroud 22 of underframe 20 there.In this way, rising yarn tube support unit 14 and yarn guide parts 16 are convenient to them easily in the slip around location of falsework 20, and are not subjected to the interference on floor.

Yarn creel 10, because moving arbitrarily and yarn tube support unit 14 and the stationkeeping ability of yarn guide parts 16 on circumference of it, just can set up adjustable yarn frame 10, so that be suitable for supporting and feeding various sizes, the yarn tube 18 of various quantity and various purposes.For example, in the application of description of drawings, the yarn creel 10 of Fig. 1-3 is to build for 48 count yarns being fed to the circular knitter of one 48 road yarn, as what mentioned in the past.According to general practice, this yarn creel 10 is suitable for supporting 48 pairs of 96 yarn tubes, and yarn tube of every centering is used for feeding, and another yarn tube is as the usefulness of spare part when first yarn tube is used up.Therefore, in yarn creel 10, each has 12 yarn tube support units 14 of 8 supporting shafts 38 to be contained on the outer shroud 22 of annular element 20, becomes 6 pairs of intervals on the circumference of yarn creel 10.Preferably adjacent another of the ratio of yarn tube support unit 14 dresses of each centering to yarn tube support unit 14 lean near so that reserve the space that is used for regularly taking out the tapered bobbin of the sky that uses up yarn and the new full yarn tube of packing into.Like this, as shown in Figure 2, being used for a kind of arrangement of the yarn creel 10 of 48 yarns, is a paired yarn tube support unit 14 20 degree that are positioned to be separated by, and with adjacent another to yarn tube support unit 40 degree of being separated by.6 yarn guide parts 16 that each has 8 guides 48, can be contained in selected position and at interval on, in being contained in ring 24 around corresponding between a pair of yarn tube support unit 14 in the heart, for example, shown in Fig. 2 is 60 degree at interval.In this way, the yarn that unwinding is got off from the yarn tube 18 from each the paired yarn tube that is contained in the there any one, arrives guide 48 in fact in an identical manner on radially inner track.The yarn tube runs in the continuous plastic pipe 50 from guide 48, and by the yarn feeding device of there to corresponding circular knitter.

Be apparent that very much, yarn creel 10 is by any increase, removal and arrange yarn tube support unit 14 and yarn guide parts 16 again around, can be used for regulating productive capacity, or enlarge or reduce, the principal element of restriction yarn creel full output is to keep enough intervals between the right adjacent yarn tube support unit 14 of difference, so that the new full yarn tube that allows to pack into replaces the yarn tube that uses up.Significantly, can change at interval between a pair of yarn tube support unit 14 particularly can reduce when two yarn tube support unit 14 upper supports full fully yarn tube necessary interval.Usually be to postpone as far as possible for a long time preferably when making the yarn that uses on the yarn tube that is used for feeding that standby yarn tube is placed on the yarn creel known to.Thereby, reduce standby yarn tube and do not make land used be placed on the time that stockpiles velveteen and Soft flocks on the yarn creel.Like this, the performance that can move arbitrarily according to the yarn tube support unit 14 on the creel 10, interval between the double-type yarn tube support unit 14 can reduce greatly, it only be subjected to a full yarn cylinder size and allow to use in the yarn tube will use up the restriction of size, and do not damage and do not hinder knitting workman that the virtual rating of all standby yarn tubes was installed before the yarn tube uses up.

Like this, yarn creel 10 provides the remarkable advantage of much comparing with traditional yarn creel.The first, yarn creel 10 can utilize existing place, knitting workshop more economically, thereby the productive capacity of bigger unit area can be provided, and reduces too high cost.Because the circular nature of yarn creel 10, it is compacter than above-mentioned common straight line yarn creel.In addition, the yarn tube that the performance-adjustable of yarn creel 10 allows to hold varying number is supported and feeds, and under the ground-surface situation that does not increase the shared knitting workshop of yarn creel 10, can hold the yarn tube of different size.On the contrary, the common yarn frame that cannot regulate is the yarn tube design-calculated for fixed qty, during bigger if desired yarn tube bearing value, must use other yarn creel, or yarn creel device, certainly other place must be arranged, in addition, common yarn creel normally build in order to hold by maximum sized yarn tube.Therefore, if when using less yarn tube, then common yarn creel is adjusting function and cause the waste in space for want of.On the contrary, if when the yarn tube that uses is bigger than common yarn tube, just so common yarn creel can not hold down them.In addition, because radially moving towards of the rest pin that the circular nature of yarn creel 10 provides together with the tapered characteristic of common yarn wound packages, the a pair of side to the yarn tube that can cause adjacent supporting more is parallel to each other than the side of the yarn tube on the common yarn creel, therefore, the yarn tube can install more near a bit.Net result, yarn creel 10 provide the storage capability and the feeding ability of the unit area more much bigger than the yarn creel of common any known structure form.Can consider the underframe 20 of yarn creel 10 is made the specification of two or three different-diameters, to satisfy the yarn tube bearing value of common needed four corner substantially.

The quality that yarn creel 10 of the present invention can also help to reduce total labour cost considerably and improve the knit goods of being produced by knitting operation.The compactedness of yarn creel 10 has also reduced the floor area by knitting workman necessity of required covering in the regular supply of keeping yarn creel 10 and when replenishing standby yarn tube.Therefore, knitting workman can keep an eye on the many yarn tubes of quantity better and perhaps can keep an eye on a fairly large number of yarn creel and knitting machine.About this point, the comformability of 10 pairs of different size yarns of yarn creel tube allow to use such yarn tube, and promptly the yarn cylinder size is than the big of common use and therefore need less spare part, and then can make knitting workman bear more responsibility.In addition, the double-type yarn tube of above-mentioned permission support unit is located arbitrarily, the alerting ability that is close together fully, make the maintenance personnel before installing a standby yarn tube, the yarn tube that is using be stopped, so just exempted and trained knitting workman and monitor that they observe necessity of common routing process, with the more close characteristic of double-type yarn tube support unit, it is big that the circular nature of yarn creel 10 makes that the distance between yarn tube support unit and the yarn guide parts might be made than common yarn frame, therefore, between them, provide one more straight, more straight yarn route, reducing friction force on the yarn, and make the tension variation of yarn and generation reduce to minimum.And in order to save the place, the more close extraction guide of the yarn tube of ordinary stent, and bigger with the relative angular displacement of extracting guide out, thereby cause producing the problems referred to above.

What Fig. 4 and Fig. 5 represented is improved yarn tube support unit, respectively with 52 and 54 expressions, these two kinds of structures can replace the yarn tube support unit 14 of the yarn creel 10 among Fig. 1-3, at first with reference to figure 4, yarn tube support unit 52 is made by the straight square metal tube 56 of certain-length, side in pipe 56 end is made groove 58, so that be installed on the outer shroud 22 with clamping element 32, and the pipe 28 of its mounting means and above-mentioned yarn tube support unit 14 the same.When pipe 56 when installing on the outer shroud 22, many yarn tube supporting arms 60 be arranged into over the ground that the back side one side of making a side of groove on the square tube 56 is installed in case holding arms 60 be configured in outer shroud 22 radially to the inside.Each yarn tube supporting arm 60 is made by the round steel that bends to " Z " font, and its hold-down arm 62 is shorter, and centre portion 64 relative hold-down arms become to determine angle, and principal arm 66 and centre portion 64 are at angle, extend towards hold-down arm 62 opposite directions.The hold-down arm 62 of each arm 60 extends through pipe 56 rotationally, in fact perpendicular to the longitudinal centerline of managing 56, so that arm 60 rotates round hold-down arm 62.Supporting shoulder 68 is soldered near below the installation site of the hold-down arm 62 of every pair of arm 60, so that the centre portion 64 of two arms 60 is connected, they are bearing in one by on two arms 60 control position fully in line shown in Figure 4, there, two centre portions 64 are laterally stretched out in the opposite direction by pipe 56, when being contained on the outer shroud 22 of falsework 20 with box lunch pipe 56, make principal arm 66 radially inside.Best, centre portion 64 62 one-tenth one of the relative hold-down arm of each arm 66 are a bit larger tham the angle of 90 degree.For example, the 98-99 degree, the direction near normal centre portion 64 of principal arm, by K/UP a little in the common plane of hold-down arm 62 and centre portion 64, therefore, principal arm 66 is facing to the diametric(al) of falsework 12, and is inclined upwardly a little on its control position.Small clevis pin with head 70 is protruding near the top of every pair of arm 60 by pipe 56, so that provide a stop when moving on the off-position for each arm 60, centre portion 64 is against small clevis pin with head 70, as in Fig. 4, shown in the arm 60 that dots there.

Referring now to Fig. 5,, yarn tube support unit 54 is made by the straight round steel pipe 72 of certain-length, is shaped on groove 74 in its end, and is the same with pipe 28 forms of yarn tube support unit 14.Many arm members 76 are along 72 lamination mounted in pairs.Each arm member parts 76 comprises cover for seat 78, be enclosed within slidably pipe 72 around, and arm 80 is radially outward stretched out by cover for seat 78, the arm 80 of every pair of arm 76 parts has by arm 80 two opposite sides limits vertically outwardly directed yarn tube supporting shaft 82.Many screws 84 are screwed to fluting one side of pipe 72 at a certain distance, and its distance is for being suitable for supporting the cover 78 of the double-type arm member 76 of predetermined lamination above-mentioned.Each cover 78 has a groove 86, built in its following portion, groove 86 should be a bit larger tham 90 degree approx with the interval of arm 80 of cover on circumference, 98-99 degree preferably, along circumferentially away from the direction of the bearing pin on the arm 80 82, so that a relevant screw 84 is packed in the groove 86, thereby arm member 76 is positioned on the control position, on this position, the bearing pin 82 of arm member 76 radially inwardly stretches out towards the outer shroud 22 of falsework 20, as arm member among Fig. 5 76 ' indicated.Be inclined upwardly a little on the arm 80 of each bearing pin 82 by it.The longitudinal sliding motion on pipe 72 arbitrarily of each arm member 76, so that make groove 86 break away from screw 84, around pipe 72, rotate then, as arm member among Fig. 5 76 " shown in like that; for each arm member 76 is turned on the off-position; there, arm 80 stretches out towards the diameter foreign side of falsework 20.

Therefore, each yarn tube support unit 52,54 is finished the effect of above-mentioned two yarn tube support units 14.The rotation of the arm member 60,76 of each embodiment is convenient to take off in the following manner the yarn tube that uses up and the new full yarn tube of packing into.When the yarn tube exhausts, the operator at first handle reach top on the arm member 60,76 of adorning the yarn tube or below, under situation about they need not be removed from control position, take off the yarn tube supporting member of bevelled or other shape from main leg 66 or bearing pin 82.When the operator catch use up in falsework 12 diameters the side the yarn tube time, holding arms 60 or 76 turns to its off-position, take off the yarn tube supporting member that uses up by the place that occupies by arm member 60 or 76, new full yarn tube is placed on main leg 66 or 82, catch new yarn tube, arm member 60 or 72 is rotated back on its control position again.Clearly, the arm member 60 and 76 of yarn tube support unit 52,54 has been no longer necessary for and has taken out the yarn tube and the new full yarn tube of packing into that uses up, and reserves between adjacent yarn tube support unit at interval.Therefore, can on the circumference of the outer shroud 22 of falsework 20, arrange yarn tube support unit 52,54 more closely, only be subjected to the size of the yarn tube that using and need prevent the restriction that adjacent yarn is in contact with one another.Therefore, use yarn tube support unit 52,54 also will save bigger place, therefore, further promoted the development of the support unit 14 of above discussion than yarn tube support unit 14.Give an example in passing, by yarn creel of the present invention, the diameter of the outer shroud 22 of its support 20 is 84 inches, and by utilizing 14 yarn tube support units 52 or 54, each support unit has 8 pairs of totally 16 arms, can support maximum outside diameter and be 10.25 inches 224 of yarn cones.
