Description
Technical field
The present invention relates to a kind of thread-measuring feeding device (yarn measuring feedingdevice).
Background technology
Thread-measuring feeding device is used for jet loom, especially owing to air-jet loom, to reach following purpose: extract weft material from the yarn holder; Store coiling (winding) on storage member (storage body) medially, coiling is in contact with one another or is separated from each other in this storage member; With on the direction of storage member front end, transmitting of relay storage around yarn (yarn winding); During inserting operation and throw a spear (pcik), each only discharges the coiling of the some of measuring by the unwinding brake equipment; And finally for example stop throwing a spear by brake equipment.
In addition, international publication number is that the patent documentation of W0-A-02/33157 discloses thread-measuring feeding device, this device is furnished with a very little storage member of a diameter and a brake equipment, described brake equipment has a banking pin, this banking pin measure respectively be used for unwinding to be discharged around the yarn number and stop throwing a spear around the yarn number, and the controlled weft folder on the unreeling direction that is positioned at before the storage member starts each action of throwing a spear.Released continuously in the coiling that storage yarn surface forms by the coiling element, so that it also moves to banking pin one predetermined final position.Because each is throwed a spear and is all pressed from both sides by controlled weft, for example the banking pin with retraction starts, and because the front end of storage member is positioned near banking pin terminal position back, thereby a plurality ofly discharge front end and engage brake pin subsequently with a tubular configuration around yarn, until next beginning of throwing a spear, wherein discharge around yarn, we can say, keep free aloft and do not have in-to-in to support, during taking place until throwing a spear and throwing a spear, it is returned towards the banking pin unwinding subsequently.In some cases, around yarn the external orientation surface only is set to what discharge.This principle allows to have height throw a spear frequency and the moderate relatively loom of the height of speed of throwing a spear and inserts nozzle pressure, this is main because be with any inner support ground to discharge by wind the line and the storage member of use minor diameter, has prevented to hinder the formation of the air ring (balloon) of unwinding to a great extent.Yet, when use to discharge around yarn the time, the danger that may tangle and form, described entanglement can cause fabric defects and/or yarn breakage.It is inter-adhesive and simultaneously by the situation of unwinding that two coilings sometimes can take place.For this reason, in some cases, in storage member central authorities one pin is set, this pin protrudes from the front end of storage member at unreeling direction, and this pin should be eliminated the danger of tangling and forming.Yet facts have proved that although take this measure, some weft materials are easy to form and tangle.
Summary of the invention
One of purpose of the present invention provides thread-measuring feeding device, and this thread-measuring feeding device has been avoided the formation of tangling reliably in height is throwed a spear the operating process of frequency and the high speed of throwing a spear.
According to purpose of the present invention, provide a kind of yarn to survey long and yarn feeding device, it comprises a fixing storage member, an one coiling element and a brake equipment, described storage member limits a storage yarn surface by front end restriction that is used for around yarn, described coiling element drives rotationally with respect to the axle of storage member along storage member, described brake equipment is used to measure the length of yarn, wherein: at least one extendible portion protrudes from front end from storage member on unreeling direction, this extendible portion is asymmetric with respect to axle, and form a linear upholder, this upholder be used for around the medial support of yarn around yarn, describedly outside front end, be released around yarn, and above support surpasses front end at unreeling direction and prolongs storage yarn surface, and one reflecting surface protrude from front end, this front end is radially relative with upholder, and tilts to upholder on unreeling direction.
Described extendible portion before throwing a spear and during throwing a spear for providing one around yarn only in the internal support of part. this upholder and the reflecting surface effect that converges towards upholder, so that each is released in outer in fact only being supported on point-like ground by this upholder around yarn of storage member front end, but substantially inwardly pull to the theoretical extended line of storage member axle, and the remainder of its 360 ° of scopes does not have the air ring effect at unspooling operation without any inner support. the yarn irregular movement during the friction at upholder place and the unwinding that causes by the upholder action that therefore deliberately produces make astoundingly each the most preceding around yarn be separated reliably and unwinding individually. in this way, eliminated the danger of tangling and forming. in addition, the bevelled reflecting surface has hindered coiling to become tight at extendible portion, this is because each has the coiling that becomes tight trend all to push away from extendible portion by the inclined-plane of reflecting surface. this reflecting surface can originate in the external diameter of storage member. under the simplest situation, extendible portion is a kind of right-angled triangle, for example be two dimensional surface surface or only form by bar, described bar limits this and is the cathetus and the hypotenuse of right-angled triangle at least substantially. because each coiling is directly extracted out to interior theoretical extended line direction at the storage member axle at 360 ° largest portion at unspooling operation, thereby avoided significant, produce the air ring effect of disturbing. around yarn suitably at the unspooling operation quilt, use in order and continuously, weft yarn up to final elongation discharges from extendible portion, and directly extend to the banking pin of brake equipment, banking pin stops throwing a spear action subsequently. and the good effect of extension is wonderful, should have certain adverse effect from storage yarn surface towards the extension of loom because regard as in fact originally in the unwinding path.
Thereby upholder is positioned at 12 o ' clock positions of storage member-promptly with respect to the tip position-generation of the gravity direction advantage around the symmetric support of yarn to hanging, and helps to prevent the eccentric motion of bad yarn at unspooling operation.In addition, each is supported on the top around yarn by the center of upholder, and each all moves on this upholder around yarn, so that it can be by around the rotation of storage member axle and be shifted.Linearity contact between yarn and upholder is enough for obtaining required suspension strut, and also makes the friction drag around yarn of pulling out littler.Yet, also might use wideer upholder or have the upholder on a surface, for example in order to control around yarn, to provide a bending in a wide opening by the natural characteristic that uses thread material.If under opposite situation, from storage member discharge around yarn only from the guide surface lower support, extendible portion also can be positioned at for example 9 o ' clock positions of storage member.
The storage yarn surface of storage member is limited by the outside face of finger aptly, and described finger threaded shaft is spaced apart with (intermediate) of centre.Preferably, described finger freely stops at the front end of storage member.The upholder of extension prolongs from one of them outside face of finger.In this case, if the transition that is not showing between the outside face of upholder and finger, this suits.
The upholder of extendible portion-prolong from the outside face of finger-should directly be provided with aptly at finger.In some cases, extendible portion even can be integral (unitarily) with finger.
For restrain the extendible portion that causes by operation vibrations other move, extendible portion can be supported on the storage member extraly, for example is supported on the radially relative finger.
Because in some cases, the difformity of extendible portion can cause best effect to different thread material, therefore, if extendible portion then is preferred being arranged on the storage member by the mode that another extension with other shape is replaced.
In a simple embodiment, extendible portion is made of a bar of for example being made by plastics or metal filament.Perhaps, even a blade can be set, and its cutting edge or back constitute upholder.
The bevelled reflecting surface that will push away from extendible portion around yarn aptly even incorporate extendible portion into wherein is easy to become tight around extendible portion around yarn.
In another embodiment, extendible portion can be a bevelled cone or a truncated cone. the base diameter of described cone or truncated cone can be less than the diameter of storage member front end. in this case, when each when yarn arrives upholder, just at once at the largest portion intramedullary expansion of its 360 ° of scopes. described cone or truncated cone constitute upholder and reflecting surface.
The extendible portion that is made of cone or truncated cone can have a straight line, projection or recessed bus (generatrice) respectively.
Perhaps, extendible portion can be the ducted body with narrow side, upper and lower and rectangle or oval cross section.The width of cross-sectional plane should equal the width of the outside face of the finger that combines with extendible portion at least.
In this case, upholder is convenient to be formed by the narrow side of ducted body, and this narrow side aptly therebetween the position slight curvature or for flat be circular at its edge.A narrow relatively side of ducted body then constitutes reflecting surface, and this reflecting surface extends towards the inclination angle of the cusp field of ducted body with one.Other yarn control assembly at thread-measuring feeding device needs in this zone under the situation in space, and this reflecting surface can be in the external diameter of storage member.
Upholder can extend in mode parallel with axle or that converge.One predetermined converge or downward-sloping bending can help unspooling operation around yarn converge and/or around the use of yarn.
In addition, be provided with at the upholder place one on unreeling direction downward-sloping end portion suit.This is favourable for the unwinding process, and prevents to arrive the dropping around yarn of stayed surface end.
When reflecting surface has one when being parallel to storage member the tip of the axis part substantially, being eased from the trend that upholder lifts at unspooling operation of release around yarn.
When banking pin along when yarn move, for fear of the upset around the correct arrangement of yarn on the upside of storage member and the upholder is influenced, can suit at 6 o ' clock positions of the storage member of downside banking pin being set with respect to gravity direction.Aptly, banking pin and finger synergy, this finger becomes radially relative substantially with the finger that is prolonged by upholder.Basically, the geometric configuration of extendible portion should be able to be guaranteed can be suspended on extendible portion in no instance at the yarn of the terminal point extension of unwinding process, but discharges from extendible portion, and directly stretches towards banking pin subsequently.
In addition, if banking pin is set to move and radially to engage in unreeling direction, the direction opposite with unreeling direction the guide groove of storage member, to suit, described groove limits the final position of banking pin at the terminal point that is moved by the banking pin that causes around yarn, in this final position, banking pin stops insertion process.In order to start insertion process and support shute during operation, behind the banking pin retraction, discharging and place on the upholder at the front end of storage member around yarn in addition is provided with controlled weft folder in the downstream of the front end of storage member and suits.
Be positioned at below the storage member and the guide surface on the unreeling direction behind the front end provides an extra upholder around yarn that is used to discharge, this upholder is favourable to unwinding.Yet guide surface only works from the outside around the yarn bag of the release of tubular configuration.
Since because the kinematics of throwing a spear, may take place from what storage member pushed away to be easy to from the upholder lifting and/or to be easy to form the trend of entanglement around yarn, thereby being provided with on storage member that covering surfaces suits outside one, this covering surfaces reaches the back of front end on unreeling direction.By this measure, unwinding yarn behavior or yarn geom during throwing a spear will improve.
Upwards climb and/or form entanglement around yarn at unspooling operation for fear of what discharge, if covering surfaces can be able to bend and stretch, to suit, wherein covering surfaces outwards bends and stretches and limits a yarn Wire Winding gap between the outside face of finger and upholder.In this gap, held and be directed pushing away the gap around yarn abreast in an orderly manner.
In this case, covering surfaces can suit from the outside face opposite external side preload with finger and upholder with rebounding.Thereby the irregular part of yarn and/or tangle no problem ground is passed through.
Transfer on the surface of upholder along its path from finger in a controlled manner in order to make the yarn coiling, covering surfaces extends and the end that surpasses upholder suits with its front end edge finger with along upholder from the coiling element. and extend beyond the zone of the end of upholder at covering surfaces, covering surfaces has been restrained the coiling that discharges in the unspooling operation trend of climbing upwards.
Aptly, covering surfaces is formed by the downside of a spring assembly.This spring assembly can be flat or is rod or linear.
In a suitable embodiment, described spring assembly is a leaf spring, and this leaf spring can be fixed on the upholder of fixing with rebounding.Aptly, described leaf spring can along a tilting axis can rebound the ground deflection, this tilting axis is basically parallel to the storage member axle and extends, and be set to and leaf spring and upholder between the contact zone have a lateral deviation.By this measure, leaf spring can be constant relatively but power that can easily surrender reacts on the yarn coiling.
In an embodiment preferred, described leaf spring is fixed in upholder under the help of at least one spring body, and this spring body has been fixed leaf spring and allowed leaf spring easily to surrender.
Aptly, leaf spring has a sweep at least one end, preferably towards the coiling element end, this sweep towards the direction that deviates from storage member.This sweep allows around yarn control of access gap gently, and eliminates the danger that coiling may be stopped up at leaf spring.

When coiling element 2 rotates, banking pin 3 and as one man moves to final position (roughly as shown in the figure) by the motion forward around yarn subsequently on unreeling direction W two continuous guide grooves 4 that inserted from an advanced position near coiling element 2 between yarn.This final position is limited by guide groove 4.Banking pin stops the unwinding (and insert operation or throw a spear) of yarn in this final position.Described motion forward is by batching (winding-on) action and/or producing around the yarn disengagement gear by unshowned storage member K.
Storage member K has a front end 5, the front of this front end 5 is provided with controlled weft folder C on unreeling direction W, the effect of this yarn folder is to start insertion operation separately on the one hand, be temporarily to hold weft yarn on the other hand, described weft yarn extends to storage member K from the insertion device of unshowned loom.
Banking pin 3 can be arranged on a certain zone of storage member K, for example at the downside with respect to gravity direction G, for example in the position at 6 o'clock.
Position 7 (for example at 12 o ' clock positions) with respect to the top of the storage member K of gravity direction G is provided with an extendible portion V, and this extendible portion V protrudes from front end 5 (extendible portion V and storage member are integral or for interchangeable).The extendible portion V-arrangement becomes a upholder A, and this upholder A extends at unreeling direction W substantially, this upholder A be at least linear and as support discharge from storage yarn surface 6 around yarn so that around yarn in supported live when this upholder hangs down.At upholder A opposite position substantially radially, a reflecting surface 16 links to each other with upholder A.Reflecting surface 16 originates in the external diameter or the more inside a little place on storage yarn surface 6, and extends back obliquely at unreeling direction W, shown in figure in for extending upward.
Extendible portion V among Fig. 1 can for example be a simple bar 8 or a blade 9, and its back limits above support A.Extendible portion V is asymmetric with respect to axle X, and be designed to be released on the upholder A with end 5 from storage member K each contact around yarn.At downside, storage yarn surface 6 prolongs above front end 5 by guide surface 22 plane or concave surface (shown in dotted line), and a covering surfaces 23 can be arranged on the upside and the downstream of front end 5.
Extendible portion V among Fig. 2 is a bevelled cone 10 or a bevelled truncated cone 11 at storage member K place, and this cone 10 or truncated cone 11 are configured such that upholder prolongs storage member surface 6 substantially at tip position on unreeling direction W.Cone 10 or truncated cone 11 can have one in all sides all be osed top outer or, can form by independent a plurality of bars.Cone 10 or truncated cone 11 have a base portion 12, and its diameter in some cases can be less than front end 5.Yet should be avoided between storage member surface 6 and the upholder A has transition.Base portion 12 is not necessarily circular, and can be oval or can be designed to be another shape.The downside of cone 10 or truncated cone 11 constitutes reflecting surface 16.
Extendible portion V among Fig. 3 is the blade 17 that is positioned on the storage member K, and this blade forms upholder A by the side 13 of a flat side or a convex curved.This upholder A ends at an end portion 14, and this end portion 14 is in more violent downward-sloping of direction to axle X, and leads to a cusp field 15.This cusp field 15 can be circle or obtuse angle shape in some cases.Narrow side, the bottom of blade 17 defines reflecting surface 16, and this reflecting surface 16 tilts or protrudes circlewise or recessed being inclined upwardly towards cusp field 15 at unreeling direction W.
Storage member K among the thread-measuring feeding device F shown in Figure 4 is made up of finger 18, this finger 18 around axle X in a circumferential direction with certain spaced apart.Described finger 18 freely stops and limits a polygon-shaped storage yarn surface 6 with its outside face 19.The diameter on the storage yarn surface 6 that is limited by finger 18 is less relatively, for example equals the common capacity of yarn that most of thread material stores certain sweep substantially, for example equals only between the 25mm to 50mm.
In the case, extendible portion V is that a cross-sectional plane is rectangle and the ducted body (or a solid) with bottom and upper narrow side substantially. the narrow side of described upside limits upholder A, this upholder A prolonged be positioned at the top with respect to gravity direction finger 18. aptly, this upper narrow side is the same wide with the outside face 19 of this finger 18 at least. upholder A, the outside face 19 that also has finger 18 in some cases, by end portion 14 continuities, this end portion 14 is downward-sloping more precipitously, in this example, to obtuse angle cusp field 15, above support A is parallel with axle X, or it is straight or in the downward-sloping extension of slight curvature on the direction of axle X. this cusp field 15 for example is arranged in greatly on the theoretical extended line of the axle X of storage member K. in graphic embodiment, ducted body (or solid) 20 has flat, wideer side. under the situation of oval cross section, this wideer side will be convexly crooked. and narrow side, described bottom constitutes reflecting surface 16, this reverse side 16 is inclined upward to more precipitously relatively that cusp field 15. ducted bodies 20 can be integral with finger 18 or can be arranged at finger 18. in interchangeable mode and an extra upholder 21 can be set in finger 18 places in the lower end zone of narrow side 16, bottom, this upholder 21 is arranged at lower side or storage member K, more stably to support extendible portion V. in graphic embodiment, the extra fixture 21 of extendible portion V be positioned at bottom finger 18 ', unshowned banking pin 3 (see figure 1)s and this finger 18 ' synergy among Fig. 4. the plate that is presented at the downstream of storage member K can be used as the controlled weft folder C among fixing Fig. 1, perhaps can be with fixing other equipment part or sensor, also be configured for simultaneously outer guide surface 22, describedly axially released from storage member K around yarn around yarn.
Although be not the situation an of necessity, coiling element 2 is driven continuously, has the speed of variation in some cases so that on storage member surface 6 form continuous newly around yarn, wherein when banking pin 3 retractions, be passed to forward on the upholder A at unreeling direction W around yarn.Simultaneously, the downstream part of weft yarn is still held by yarn folder C.After yarn folder C opens, used from upholder A continuously around yarn.Banking pin 3 can be at that time or even arrive the final position of guide groove 4 theretofore.Insert operation or throw a spear stop by banking pin 3 after, extend to banking pin 3, at unreeling direction one side last around yarn finally by from extendible portion V unwinding, and will extend to banking pin 3 from yarn folder C subsequently substantially straightly.
Subsequently, yarn folder C clamps weft yarn.Banking pin 3 will bounce back and move towards coiling element 2 with the direction opposite with unreeling direction W, and subsequently once more before yarn will be delivered to banking pin 3 final position in the guide groove once more, between two coilings, being pushed of forming subsequently.
In view of guide surface 22 from downside supporting release around yarn, extendible portion V even can be arranged on 9 o ' clock positions of storage member K for example or in the another location is not promptly in the position at shown 12 o'clock.
The characteristics of the embodiment of Fig. 5 are that the structure of extendible portion V is especially simple, the basic at right angles triangle 24 of this extendible portion V, and wherein a cathetus limits upholder A, and hypotenuse constitutes acclivitous reflecting surface.This triangle can be the triangular blade on a plane as shown in the figure, perhaps can be made up of another bar of a bar 8 and qualification reflecting surface 16.In the case, aptly, two bars can interconnect in the vertex of a triangle district.
The embodiment of Fig. 6 has also adopted the extendible portion V of the fundamental triangle similar with Fig. 5.The guide surface 22 that is positioned at the downside of upholder A is arranged on 9 o ' clock positions, and reflecting surface 16 is arranged on 3 o ' clock positions.
The embodiment of Fig. 7 (lateral plan) has the embodiment that especially suits of the extendible portion V of storage member K.A straight substantially upholder A who prolongs from the storage yarn of storage member K surface 6 leads to cusp field 15 by a more precipitous bevelled end portion 15.Reflecting surface 16 has an end portion 25, and this end portion 25 is extended with the axle X that almost is parallel to storage member K, promptly with more small inclination extension of ratio inverse surface 16, and ends at cusp field 15.End portion 25 helps to restrain the trend that upwards rises from upholder A at unspooling operation around yarn.
Core of the present invention is to provide the storage member of the thread-measuring feeding device with an extendible portion, described thread-measuring feeding device allows best height the throw a spear frequency and the speed of throwing a spear, described extendible portion obtains the so many harmful effect to unwinding yarn, frequency and the speed of throwing a spear be not affected (this this design to thread-measuring feeding device is possible) so that throw a spear at all, and two will be not can not stick together or form entanglement around yarn at unspooling operation. the influence of extendible portion is limited in each local location in 360 ° of scopes of yarn substantially, can not directly inwardly be pulled to the theoretical extended line of storage member axle around yarn in this position. this has such effect, promptly can insert from the tubular configuration that discharges reliably, be separated from each other reliably and can't tangle around yarn simultaneously around yarn bag (yarn winding package) around yarn.The extendible portion upholder depends on yarn diameter in the selection of the length of unreeling direction, and can be substantially equal to the length on storage member storage yarn surface aptly.Prevent that becoming tight reflecting surface around yarn at extendible portion can begin place's design at its of storage member, the yarn that is used for other needs is controlled or the space of sensor element so that have.
Fig. 8,9 and 10 has shown the simple and clear embodiment of Weft thread length measuring device F, and this Weft thread length measuring device F has a specific implementation of schematically illustrated covering surfaces 23 in Fig. 1 only.The upholder 28 of one out rigger (outrigger) shape is connected to housing 1 by a fixture 27.One leaf spring 29 is in the upholder 28.The downside of leaf spring forms outer covering surfaces 23.
According to Fig. 8,9 and 10, leaf spring 29 is fixed in the upholder 28 by at least one spring body 30, specifically is to make spring body 30 limit one with respect to the outside face 19 of upholder A and the finger 18 bevelled axle to the side deflection.The axle that this tilting axis is basically parallel to storage member K extends.In some cases, leaf spring 29 can gently be pressed on the outside face 19 of finger 18 or on the upholder A of extendible portion V, so that leaf spring can move in the direction of double-head arrow 31 with rebounding.The preceding end of leaf spring 29 is positioned on the unreeling direction W, and becomes certain distance with coiling element 2 (Figure 10).Leaf spring 29 extends to upholder A foremost at least, and with outside face 19 and upholder A common limit a longitudinal extension around the yarn control gap.At least at the end towards coiling element 2, leaf spring 29 has one towards the bending 32 away from storage member K.
According to Figure 10, extendible portion V and finger 18 are one, so that do not have transition between extendible portion V and finger 18.Covering surfaces 23-for example is made of-replaces with can be arranged at outside face 19 leaf spring 29 and becomes a bit of distance with upholder A, condition is it in operating period of Weft thread length measuring device A with a weak effort in around yarn, and guarantee not to be pulled on another yarn each other, and can be upwards not soaring from upholder A at unspooling operation around yarn.
