Description
Technical field
The present invention, relate to the weft long measuring storing apparatus in the shuttleless loom and the establishing method of the pin position in this weft long measuring storing apparatus, the weft long measuring storing apparatus that relates in particular to following a kind of pattern promptly, have: utilize inactive state store rotating cylinder around continuously the rotation thread-carrier of rotation weft yarn is wound on store on the rotating cylinder, by described relatively store rotating cylinder around advance and retreat card that the card shotpin that drives carries out this weft yarn end and unclamp store device; And will be from the weft yarn of yarn feeding body to above-mentioned rotation thread-carrier, measuring motion to send continuously with the winding speed speed about equally of this rotation thread-carrier, before picking begins, be wound on that described to store weft yarn on the rotating cylinder released and begin picking, then, the weft yarn of sending from the described measuring motion constraint of carrying out direct picking by the described rotation thread-carrier picking of mode of flying away.
Again, in this specification, the record of position about the card shotpin, be meant the position of the axis of card shotpin, for example, so-called " card shotpin and the clamped position that stores rotating cylinder ", the position that the axis that is meant the card shotpin and the side face that stores rotating cylinder intersect, again, so-called " straight line that the card shotpin is connected with the center that stores rotating cylinder " is meant the straight line that the center of card shotpin front end is connected with the center that stores rotating cylinder.
Background technology
As the weft long measuring storing apparatus in the shuttleless loom of above-mentioned pattern, known have a device of being put down in writing in patent documentation 1.The long measuring storing device of record in this patent documentation 1 has: during the concluding time from concluding time of picking to picking next time, only with the rotation and carry out the rotation thread-carrier of coiling action of the weft yarn that stores rotating cylinder of relative static conditions continuously of predefined regulation revolution; And make weft yarn from the yarn feeding body rotate thread-carrier, measuring motion relatively to send continuously with the winding speed speed about equally of rotation thread-carrier.And, in the time started of the picking of stipulating, the card shotpin from store the state that rotating cylinder engages and begin to retreat driving, change the state that weft yarn can be unclamped into, with this pressure fluid by using from Weft insertion nozzle injection picking, be wound onto before this and store the weft yarn that is in the state of storing on the rotating cylinder, unclamping and carry out picking (picking of the formula of freely flying away) when forming air ring from storing rotating cylinder.
Again, since the long measuring storing device of this pattern be carry out thread-carrier with following form driving promptly, during rotation 1 circle that is equivalent to loom, reel by the weft yarn of 1 part (part of 1 coiling traverse) length of picking storing on the rotating cylinder, so utilize the winding speed of rotation thread-carrier, than slow from storing the speed of on the rotating cylinder weft yarn being unclamped, for half or below it along with picking.Therefore, during picking in, even after picking begins, utilize the coiling action of rotation thread-carrier still proceeding, but store the weft yarn on the rotating cylinder, little by little reduce along with the carrying out of picking.And in the final period of picking, the weft yarn that stores on the rotating cylinder is released fully, finish to picking after it, the weft yarn of sending from measuring motion become from the rotation thread-carrier directly (not by storing rotating cylinder) draw the state that the constraint of carrying out picking is flown away.Again, in the picking (being designated hereinafter simply as " constraint is flown away ") of mode was flown away in this constraint, weft yarn was at the rotation thread-carrier and store between the thread-carrier in rotating cylinder the place ahead, was drawn with a linearity ground.
In this process, after the rotation thread-carrier that should carry out last 1 rotation of card shotpin before finishing by picking, the side face turnover to storing rotating cylinder becomes the state that the weft yarn card can be ended.
And, in the time that weft yarn finishes, being in the position of rotation of the position consistency of rotation thread-carrier and card shotpin, weft yarn is blocked the shotpin card and is only finished picking in the back.And, begin thereafter subtend next time picking store the coiling that rotating cylinder carries out weft yarn.
Again, carry out that above-mentioned constraint flies away during, be configured to the weft yarn in the picking has been considered that damage waits between the optimal period of influence.That is to say, as putting down in writing in the patent documentation 1, adopt the purpose of structure of the long measuring storing device of above-mentioned such pattern, be since picking when finishing weft yarn blocked shotpin and block immediately and end, on weft yarn, produced big tension force effect, and for the cause of damage of preventing to take place thus weft yarn etc.
But, during above-mentioned constraint is flown away, set for longer, in other words, if begin to carry out picking with the time more early from picking, the weft yarn that stores on the rotating cylinder is totally released, then since the difference of the picking speed when freely the picking speed when flying away is flown away with constraint become greatly, so when the beginning that constraint is flown away, on weft yarn, acting on big tension force, might be because of this former thereby cause damage of weft yarn etc.On the other hand, during constraint is flown away, set for shorter, in other words, if between more long-term in during picking, weft yarn carries out picking in the mode of freely flying away, then become the conventional art state such, that walk to carry out picking with free flight all that more approaches record in the patent documentation 1, the problem same with this technology in the past can take place.Therefore, constraint fly away during, consider these situations, to weft yarn decision best during set.
Patent documentation 1: the Japan Patent spy opens clear 63-21955 communique (scope that patent requires etc.)
, in the above-mentioned patent documentation 1 in the long measuring storing device of record, occurred that member that weft yarn and periphery at the long measuring storing device exist etc. contact, the problem damaged of generation thus.
That is to say, as previously mentioned, in the long measuring storing device of this pattern, the weft yarn that stores on the rotating cylinder along with the carrying out of picking little by little reduces, in the process of the 1 time last rotation before the rotation thread-carrier is carried out the picking end, because on the rotatable phase of this rotation thread-carrier, append the rotatable phase of the release point that stores the weft yarn on the rotating cylinder, so become weft yarn between the thread-carrier in rotating cylinder the place ahead and drawn the state of shape in line with storing at the rotation thread-carrier, become the state that flies away that retrains thereafter.
Again, as previously mentioned, carry out that constraint flies away during, being configured to relative weft yarn becomes state during best, in general, the rotation thread-carrier is configured to: the moment that is about the position of rotation of 180 degree from the position of relative card shotpin begins to retrain the state that flies away.And, in the long measuring storing device of in patent documentation 1, putting down in writing, be configured in the vertical top that stores the rotating cylinder center owing to will block shotpin, so beginning to retrain the period of flying away, the position of rotation of rotation thread-carrier becomes moment of the vertical lower position at the rotating cylinder center that stores in the 1 time last rotation before having arrived picking and finishing.
But, in the long measuring storing device of such pattern, in the picking of the formula of freely flying away, weft yarn little by little reduces the coiling length that stores rotating cylinder, in 1 time last rotation before the picking of rotation thread-carrier finishes, weft yarn will further reduce with the state less than 1 week to the coiling length that stores rotating cylinder.Therefore, before the zero hour that constraint is flown away (store release point on the rotating cylinder be appended to the rotatable phase of rotation thread-carrier before promptly, storing the state that also leaves weft yarn to a certain degree on the rotating cylinder), can store the released simultaneously phenomenon of weft yarn on the rotating cylinder.
Consider: this be since weft yarn to the coiling length that stores rotating cylinder little by little reduce, it is shorter in length than the length can obtain by reeling the restraining force that stores rotating cylinder and takes place.
Like this, before beginning is flown away in constraint, when being wound on the weft yarn that stores the specific length on the rotating cylinder when unclamping simultaneously, along the rotation thread-carrier and to store the length of the weft yarn between the thread-carrier in rotating cylinder the place ahead correspondingly elongated, its result, weft yarn is drawn with regard to being made to than bigger air ring before it.Again, this air ring is along with retraining the position of the zero hour of flying away near the rotation thread-carrier and little by little diminishing, after moment of beginning was flown away in constraint, as previously mentioned, weft yarn was at the rotation thread-carrier and store and become a linearity ground between the thread-carrier in rotating cylinder the place ahead and drawn.
; in loom; situation on the framework that the long measuring storing device is arranged on loom with directly supporting appears sometimes; this occasion; store the periphery of rotating cylinder, especially storing on the periphery of lower portion of rotating cylinder, often existing the member (below be called " surrounding member ") of the part of framework of supporting loom and the carriage that the long measuring storing device is used etc.
And as mentioned above, weft yarn is in below the specific length the coiling length that stores rotating cylinder, and the fly away big air ring of the weft yarn that takes place before the beginning of constraint can occur and stores the problem that the surrounding member that exists on the lower periphery of rotating cylinder contacts at this.
Especially retrain the zero hour of flying away, as previously mentioned, even set near the occasion in the moment the vertical lower position that the position of rotation of rotation thread-carrier arrives the center that stores rotating cylinder for, can occur also that rerum natura along with weft yarn changes and the coil diameter variation of yarn feeding body etc., the situation of about 10 degree of maximum delay on the anglec of rotation of rotation thread-carrier.And, begin to take place constantly with the atmospherical of this above-mentioned weft yarn, also the direction of rotation to the rotation thread-carrier is offset.Therefore, this big air ring just occurs in the position of more approaching surrounding member, the postponement of the zero hour that the length that contacts with the surrounding member of weft yarn is flown away along with above-mentioned constraint and increasing.Big damage will take place in its result on weft yarn, produce the defective of fabric or picking and can not normally carry out and the picking error takes place.
Summary of the invention
In view of the problem in the above conventional art, the objective of the invention is to, in the weft long measuring storing apparatus of above-mentioned pattern, the weft yarn that unclamps when reducing because of picking as much as possible and caused weft yarn damage of contacting of surrounding member etc. prevent fabric defect and picking error etc.
In order to arrive above-mentioned purpose, weft long measuring storing apparatus in the shuttleless loom of the present invention, it is that a kind of following pattern is, have the device of storing and measuring motion, the described device that stores, utilization is at the rotation thread-carrier that rotates continuously on every side that stores rotating cylinder of inactive state, weft yarn is wound on stores on the rotating cylinder, by the described relatively card shotpin of advancing and retreat and driving on every side that stores rotating cylinder, the card of carrying out this weft yarn ends and unclamps, described measuring motion will be from the weft yarn of yarn feeding body to above-mentioned rotation thread-carrier, to send continuously with the winding speed speed about equally of this rotation thread-carrier, before picking begins, unclamp and begin picking being wound on the described weft yarn that stores on the rotating cylinder, the weft yarn that to send from described measuring motion then, the fly away picking of mode of the constraint of carrying out direct picking by described rotation thread-carrier, its characteristics are, described card shotpin is configured to: the clamped position that store rotating cylinder described with it is in than the vertical top position at the described center that stores rotating cylinder more to the direction of rotation upstream side of described rotation thread-carrier, and, be in the scope of the position that horizontal line and the described side face that stores rotating cylinder by the described center that stores rotating cylinder intersect.
Again, preferably described card shotpin is arranged to: the straight line that described card shotpin is connected with the described center that stores rotating cylinder, relatively by the described plumb line that stores the center of rotating cylinder, angle more than direction of rotation upstream side formation 10 degree of described rotation thread-carrier, again, preferably described card shotpin is arranged to: this angle forms the roughly state of 45 degree.
Again, described card shotpin also can be provided on the described circumferencial direction that stores rotating cylinder and can adjust its installation site.
Again, the establishing method of the pin position in the weft long measuring storing apparatus of the present invention, it is in the weft long measuring storing apparatus of above-mentioned pattern, its characteristics are, be predetermined the constraint fly away mode picking during, and the set positions of described card shotpin become: the described residual yarn amount that stores the weft yarn on the rotating cylinder in making during the picking becomes the position of rotation of the rotation thread-carrier in the following moment of specific length, is in than the horizontal line at the center by the storing rotating cylinder state of top more.
Again, so-called in above-mentioned " length of regulation " is meant that the coiling length that constrains in the weft yarn that stores on the rotating cylinder by coiling reduces, its length shortens and has lost the restraining force that stores rotating cylinder, stores the length that stores the weft yarn on the rotating cylinder in the moment that the weft yarn on the rotating cylinder unclamps simultaneously.
Adopt above-mentioned weft long measuring storing apparatus of the present invention, the card shotpin with store rotating cylinder and engage, the position that the weft yarn card ends promptly, the position of the rotation thread-carrier of picking finish time, compare with the long measuring storing device of in the past above-mentioned pattern, become the upstream side of the direction of rotation of rotation thread-carrier.Therefore, the constraint of guaranteeing to be predetermined fly away during the position of rotation of rotation thread-carrier of such constraint zero hour of flying away, also become the upstream side that is positioned at this direction of rotation, become the position of rotation of the rotation thread-carrier in the moment below the specific length with this residual yarn amount on the rotating cylinder of storing, compare with device in the past, also become the upstream side of the direction of rotation of rotation thread-carrier.Its result along with the rerum natura variation of foregoing weft yarn and the coil diameter variation of yarn feeding body etc., even the delay of the zero hour of flying away takes place to retrain, also can increase to a certain degree above phenomenon to the contact length of weft yarn and surrounding member and suppress.
Especially, if will block shotpin becomes with the set positions that stores the rotating cylinder engaging: the straight line that the card shotpin is connected with the center that stores rotating cylinder, the relative plumb line at the center by storing rotating cylinder, angle more than upstream side formation 10 degree of the direction of rotation of rotating thread-carrier, this ratio of occasion when then flying away can postponing mostly of beginning period with as described above, constraint can prevent to take place along with excessive contact of weft yarn and surrounding member the situation that weft yarn damages.
Again, if will block the set positions of shotpin becomes: will block the straight line that shotpin is connected with the center that stores rotating cylinder, the relative plumb line at the center by storing rotating cylinder, angle at the direction of rotation upstream side that rotates thread-carrier, formation is for example spent much bigger angle than above-mentioned 10, be about 45 degree, then can not only prevent as described above, the delay in beginning period of flying away along with constraint and make the weft yarn situation excessive with the amount of contact of surrounding member, and what can alleviate this weft yarn and surrounding member contacts self, even employed weft yarn is the material of easy damaged, also can prevent along with damaged with contacting of surrounding member.
Again, become by the set positions that will block shotpin: make this card shotpin and the clamped position that stores rotating cylinder, the position that the horizontal line that becomes the center by storing rotating cylinder and the side face that stores rotating cylinder intersect or be in the downstream of the direction of rotation of rotation thread-carrier more than it, just can not disturb, can easily block the installation of shotpin and adjust operation etc. with surrounding member.Especially, if be set near the angle position of 45 degree as described above, then this operation just can more easily be carried out.
Again, set for by blocking shotpin: on the described circumferencial direction that stores rotating cylinder, can adjust its installation site, just can at random set the position of card shotpin in the above range, can be with the set positions of card shotpin position in the best of having considered the zero hour that constraint is flown away and the position of surrounding member etc.
Again, adopt the establishing method of the pin position of weft long measuring storing apparatus of the present invention, in the weft long measuring storing apparatus of above-mentioned pattern, make along with picking the position of rotation that becomes the rotation thread-carrier in the moment below the specific length from the residual yarn amount on the rotating cylinder of storing that stores weft yarn that rotating cylinder unclamps, be in before the rotation thread-carrier arrives near the bottom that stores rotating cylinder have surrounding member, than the taller position of the height and position of surrounding member, arrive the moment of the position of surrounding member existence at the rotation thread-carrier, because air ring eliminated to a certain extent, so can avoid the damage etc. of the weft yarn that causes along with weft yarn and contacting of surrounding member as much as possible.

The specific embodiment
Below, with reference to the accompanying drawings example of the present invention is elaborated.
Shown in Fig. 1,2 is an example of the present invention, is illustrated in the water jet loom that is fixed with Weft insertion nozzle 5 on shuttleless loom, for example loom frame 1, has adopted the object lesson of weft long measuring storing apparatus 3 of the present invention.Weft long measuring storing apparatus 3 comprises: be bearing in storing device 10, be bearing in this and store measuring motion 20 and weft yarn clamping device 30 on the device 10 on the loom frame 1.
Store device 10, its fixed cover 11 is bearing on the loom frame 1 by carriage 8, in this fixed cover 11, by bearing 12 rotatably mounted rotating shaft 13.Again, on this rotating shaft 13, in rear end side belt pulley 13b is installed, this belt pulley 13b utilizes synchronous belt 6 and driving shaft by the main shaft drives of not shown loom to move and is connected.Therefore, rotating shaft 13 is by synchronous belt 6 and belt pulley 13b, synchronously is rotated driving with the main shaft of loom, and every rotation 1 circle of loom is with predefined regulation revolution constant speed and be rotated driving continuously.
Again, near the pars intermedia of rotating shaft 13, support 17b is not installed on the rotating shaft 13 revolvably, on this support 17b, with the state that is embedded among the last hole 17d that forms of support 17b yarn-guide tube 17c is installed.And, at the front end of this yarn-guide tube 17c rotation thread-carrier 17 is installed.Again, the endoporus of yarn-guide tube 17c is communicated with thread guide eyelet 13a on being located in rotating shaft 13 by the hole 17d of support 17b, the weft yarn Y that is supplied with from measuring motion 20 described later, be directed to yarn-guide tube 17c by thread-carrier 9, thread guide eyelet 13a and hole 17d, supply with to rotation thread-carrier 17.
Again, at the leading section of rotating shaft 13, the fixed disc 15 that the rotating cylinder support 16 that forms the rotating cylinder sheet 19a that stores rotating cylinder 19 is equipped with in supporting is installed, this fixed disc 15 utilizes bearing 14 relative rotation axis 13 rotatably being mounted.But, on fixed disc 15, burying a plurality of permanent magnet 15a in its periphery underground with the interval of regulation, 15a, on the other hand, in fixed cover 11, fixing the permanent magnet 15a that has with fixed disc 15,15a, the magnetic shell 18 of the relative face of the face of burying underground, owing on this magnetic shell 18, burying a plurality of permanent magnet 18a of relative configuration underground with permanent magnet 15a with the interval of regulation, 18a, so fixed disc 15 utilizes the sucking action of this permanent magnet 15a and 18a, become the fixed cover 11 that can stop and carry out counterrotating state with respect to along with rotating shaft 13 rotations.
Measuring motion 20 comprises: be supported in the rotation roller 21 on the fixed cover 11 and be supported in roller follower 23 on the supporting arm 26 that is installed on fixed cover 11 rear ends by axle 25.
The axle 25 of supporting rotation roller 21 rotatably is supported on the fixed cover 11 by bearing 22.Again, belt pulley 25a is installed on axle 25, this belt pulley 25a is connected with belt pulley 13b by synchronous belt 6.Therefore, rotation roller 21 is by synchronous belt 6, belt pulley 25a and axle 25, similarly rotates driving synchronously with the main shaft of loom with rotating shaft 13.
Again, roller follower 23 forms the state with 21 crimping of rotation roller, between this roller follower 23 and rotation roller 21, sandwiches the weft yarn Y that draws from yarn feeding body (not shown).Therefore, by the rotation driving of rotation roller 21,, weft yarn Y is sent with the speed of regulation continuously to thread-carrier 9 to assist moving state with roller follower 23.
Again, utilize the rate of delivery of the weft yarn Y of this measuring motion 20, be configured to by the rotation thread-carrier 17 with weft yarn be wound in store rotating cylinder 19 winding speed about equally.That is to say, measuring motion 20 is configured to: during rotation thread-carrier 17 rotations 1 time, send around the weft yarn of 1 circle part storing rotating cylinder, during suitable, carry out picking, with the weft yarn constant speed of the length of 1 part and send continuously with the rotation of loom 1 time.
Weft yarn clamping device 30 is configured to: be supported in the integrally formed support 18b of the magnetic shell 18 that is fixedly attached to fixed cover 11 go up, with the relative state of rotating cylinder sheet 19a of regulation.
And, this weft yarn clamping device 30, portion has the drive unit (not shown) of electromagnetic valve etc. within it, and has the card shotpin 31 that utilizes this drive unit to advance and retreat and drive.And this blocks shotpin 31, and by the driving of advancing and retreat to the last patchhole 19b that forms of relative rotating cylinder sheet 19a, the card that just can carry out weft yarn only and from the weft yarn that stores on the rotating cylinder 19 unclamps.
The place ahead at weft long measuring storing apparatus 3, be provided with the clip 7 that is positioned on the framework 1 and thread-carrier 4a, the 4b that front and back had of clip 7, the weft yarn Y that rotating cylinder 19 is drawn that stores from weft long measuring storing apparatus 3 is directed in the Weft insertion nozzle 5 by thread-carrier 4a, clip 7 and thread-carrier 4b.
The effect of the weft long measuring storing apparatus 3 in the shuttleless loom that is made of above structure roughly as previously mentioned.That is to say, when describing according to Fig. 3, when time that picking finishes (in illustrated embodiment, the crank angle of loom be 270 degree), the position of rotation of rotation thread-carrier 17 is configured to roughly consistent with the position of blocking shotpin 31, therefore, weft yarn Y from rotation thread-carrier 17 is drawn is only blocked shotpin 31 cards in this picking the finish time, begins once more to the coiling that stores rotating cylinder 19.Again, rotation thread-carrier 17 is from this picking finish time, during suitable (to the picking finish time of next time) with the rotation of loom 1 time, only the revolution (being 5 commentaries on classics in illustrated embodiment) with predefined regulation is rotated continuously, carries out weft yarn Y to the coiling action that stores rotating cylinder 19.
Then, when arriving the time that picking once more begins (in illustrated embodiment, the crank angle of loom be 90 degree), card shotpin 31 retreats, become weft yarn Y from storing the state that to remove on the rotating cylinder 19, utilize the releasing clamping of the injection of pressure fluid of Weft insertion nozzle 5 and clip 7 and begin picking, it is released and carry out picking with the free state of flying away so far to be wound on the weft yarn Y that stores on the rotating cylinder 19.Again, during this picking in since by the release speed of picking than fast, so little by little reduce at the weft yarn Y that stores on the rotating cylinder 19 by the winding speed of rotation thread-carrier 17.
And behind the position of the card shotpin 31 of 1 rotation (coiling action of the 5th circle) that should carry out at last before having passed through the picking end, card shotpin 31 becomes the state that weft yarn Y card can be ended to the patchhole 19b of relative rotating cylinder sheet 19a turnover.Then, released fully at the weft yarn Y that stores on the rotating cylinder 19, between rotation thread-carrier 17 and thread-carrier 14a, begin to retrain the picking of the formula of flying away from the moment that weft yarn Y becomes a linearity.Again, in the zero hour that constraint is flown away, rotation thread-carrier 17 was set at from the moment of the about half cycle of position rotation (180 degree) of card shotpin 31.And, retrain the picking of the formula of flying away thereafter the finish time until picking, begin to repeat once more above action the finish time from picking.
In the weft long measuring storing apparatus of such pattern, in illustrated embodiment, compare with the pattern in the past (dotted line of Fig. 2) on the vertical top position that is located at the center C that stores rotating cylinder 19, the card shotpin 31 that stores device 10 is positioned at the upstream side of the direction of rotation (direction of the arrow K of Fig. 2) of rotation thread-carrier 17, be configured to: the straight line L that this card shotpin 31 is connected with the center C that stores rotating cylinder 19 promptly, the straight line L that is connected with the center C that stores rotating cylinder 19 to the clamped position that stores rotating cylinder 19 of card shotpin 31, the plumb line V of relative center C by storing rotating cylinder 19 becomes 45 angles of spending.(in addition, in Fig. 1, card shotpin 31 (weft yarn clamping device 30) has been depicted as the state of the vertical top position that is located at the center C that stores rotating cylinder 19, but this only is to have done such expression easily for the structure of understanding weft yarn clamping device 30 easily, in fact, same with Fig. 2, be configured to the angles that relative plumb line V by center C becomes 45 degree).
Therefore, store in the device 10 at this, the vertical top position that the position of rotation of the rotation thread-carrier 17 of picking finish time becomes relative center C is the preceding line positions of 45 degree only, with this, constraint zero hour of flying away, the position of rotation that also becomes the rotation thread-carrier 17 in the 1 time last rotation before picking finishes has arrived near the moment of the preceding line position of 45 degree the vertical lower position of decentre C.
Its result, the residual yarn amount that stores the weft yarn Y on the rotating cylinder 19 becomes below the specific length, the moment of being unclamped simultaneously promptly, the position of rotation that begins to take place rotation thread-carrier 17 constantly of the big air ring of aforesaid weft yarn, be in than the higher position of horizontal line H by center C, this center C is positioned at the more top of the surrounding member of framework 1 grade that exists than the lower periphery that stores rotating cylinder 19.And the air ring of this weft yarn Y owing to the position that will rotate thread-carrier 17 takes place as starting point, so be positioned at rotation thread-carrier 17 under the state of above-mentioned like that high position, above-mentionedly formed atmospherical weft yarn Y and just can not contact with surrounding member.
Again, the air ring of this weft yarn Y since along with rotation thread-carrier 17 near constraint fly away beginning the moment position of rotation and little by little diminish, so arrive at rotation thread-carrier 17 the surrounding member existence the position near the moment, the air ring of weft yarn Y diminishes.Therefore, the length that contacts with the surrounding member of weft yarn Y becomes enough little, thus, can avoid the situation of weft yarn Y damage as much as possible.
Again, this illustrated storing in the device 10, card shotpin 31 can carry out the position adjustment along the circumferencial direction that stores rotating cylinder 19.In detail, the magnetic shell 18 of support shute clamping device 30 by support 18b, the slotted hole 18c by forming along its periphery utilizes screw member 11a to be fixed on the fixed cover 11.Therefore, by screw member 11a is unclamped, magnetic shell 18 can be rotated along slotted hole 18c relative fixed cover 11, and by the rotation of this magnetic shell 18, weft yarn clamping device 30 can change the position along the circumferencial direction that stores rotating cylinder 19 in the scope of slotted hole 18c.
Again, as previously mentioned, store the fixed disc 15 of the rotating cylinder sheet 19a of rotating cylinder 19, utilize the sucking action of permanent magnet 15a and 18a, be prevented from relative rotation with respect to magnetic shell 18 by rotating cylinder support 16 supporting.Therefore, when magnetic shell 18 relative fixed covers 11 were rotated, fixed disc 15 also correspondingly carried out same rotation with this.Therefore, even in the occasion of the location change that makes weft yarn clamping device 30, the position relation of weft yarn clamping device 30 and the rotating cylinder sheet 19a relative with it does not change yet, and the patchhole 19b of card shotpin 31 and relative rotating cylinder sheet 19a can keep relative state.
Again, the position adjustment range of card shotpin 31 can utilize the formation length of slotted hole 18c freely to set.Therefore, than the vertical top position of the center C that stores rotating cylinder 19 more to the direction of rotation upstream side of rotation thread-carrier 17 and in by the required scope in the horizontal line H scope of center C, suitably form slotted hole 18c according to the form that can adjust card shotpin 31 and store the clamped position of rotating cylinder 19 and get final product.
In the above-described embodiment, be that card shotpin 31 is configured to: the straight line L that card shotpin 31 (card shotpin 31 and the clamped position that stores rotating cylinder 19) is connected with the center C that stores rotating cylinder 19, become the angle of 45 degree relatively by the plumb line V-arrangement of center C, and the configuration of card shotpin 31 of the present invention is not limited to this, is arranged on than the plumb line V that passes through center C more to the direction of rotation upstream side that rotates thread-carrier 17 as long as will block shotpin 31, and horizontal line H scope (the straight line L that card shotpin 31 is connected with center C by center C, the maximum scopes that form 90 degree of relative plumb line V) just can in.
And, adopt such structure of the present invention, compare with the weft long measuring storing apparatus in the past of above-mentioned pattern, can alleviate in the 1 time last rotation before the picking end of rotation thread-carrier excessive the contacting of the surrounding member on being, retraining the preceding weft yarn that takes place of the beginning of flying away and being present in the lower periphery that stores rotating cylinder.
Especially, because will block the set positions of shotpin 31 becomes: the straight line L that card shotpin 31 is connected with center C, relatively the plumb line V-arrangement becomes 10 degree or than its big angle, weft yarn Y is crossed greatly contact, also can prevent former thereby make the situation of weft yarn damaged because of this with surrounding member so can prevent delay because of zero hour of flying away along with the constraint of the coil diameter variation of the rerum natura variation of weft yarn and yarn feeding body.
Again, as above-mentioned embodiment, because will block the set positions of shotpin 31 becomes: the angle that the straight line L that card shotpin 31 is connected with center C becomes with the plumb line V-arrangement is than the above-mentioned much bigger angle of 10 degree, so can make weft yarn Y and contacting of surrounding member self become slightly little or almost become does not have, even the easy weft yarn of damaged etc. also can be avoided the damage because of causing with contacting of surrounding member.
Again, the set positions of the card shotpin 31 in above-mentioned scope is suitably set as long as consider the kind of weft yarn Y of picking and the rotating speed of rotation thread-carrier 17 etc. and just can.Again, the residual yarn amount that stores the weft yarn Y on the rotating cylinder 19 in the 1 time last rotation before the picking of rotation thread-carrier 17 finishes considered become moment below the specific length be, the position of rotation of the rotation thread-carrier 17 in moment of unclamping simultaneously from the described weft yarn Y that stores on the rotating cylinder 19 and the height and position of surrounding member, at the position of rotation of this rotation thread-carrier 17 constantly, set positions that also can card shotpin 31 becomes: be in the higher position of horizontal line H than the center C by storing rotating cylinder 19 at least.
Again, in the present invention, become by the set positions that will block shotpin 31: at the upstream side of rotation thread-carrier 17, the angle that the straight line L that card shotpin 31 is connected with center C becomes with the plumb line V-arrangement is to the maximum in the such scope of 90 degree, so can carry out installation, location and the adjustment etc. of weft yarn clamping device 30 without barrier.
In the above-described embodiments, as the structure that the position of weft yarn clamping device 30 (card shotpin 31) can be changed along the circumferencial direction that stores rotating cylinder 19, be to have made the structure that the magnetic shell 18 relative fixed covers 11 that can make support shute clamping device 30 rotate, the structure shown in Fig. 4～6 replaces it but for example also can make.
In the structure shown in Fig. 4～6, weft yarn clamping device 30 is not mounted on the magnetic shell 18, but is installed on the guide plate 11b by carriage 33, and this guide plate 11b is subjected to fixed cover 11 supportings, is installed on the side face of fixed cover 11.
Again, on the side face of fixed cover 11, guide plate 11b from the top position to the upstream side of rotation thread-carrier 17, extend along the scope in about 1/4 week, on its two ends, utilize screw member 11d, 11d the to be installed in support 11c that is integrally formed on the fixed cover 11, the upper end of 11c.Therefore, between support 11c, 11c, between guide plate 11b and fixed cover 11, exist the gap of having only support 11c height part.On guide plate 11b, as shown in Figure 6, between support 11c, 11c, be formed with screw member 33a, the 33a that spiral shell inserts on the carriage 33 and can insert logical slotted hole 11e, 11e again.
And, and the opposition side of the carriage 33 of guide plate 11b promptly, the gap between fixed cover 11 and the guide plate 11b with carriage 33 corresponding positions on, be provided with fixed component 33b, screw member 33a is screwed in this fixed component 33b.
Therefore, storing in the device in this embodiment, fastening by screw member 33a, 33a are carried out, become by carriage 33 and fixed component 33b guide plate 11b is carried out fastening state, thus, the position of the carriage 33 of guide plate 11b is fixed relatively.On the contrary, by screw member 33a, 33a are unclamped, profit is disengaged by the tightening state of the guide plate 11b that carriage 33 and fixed component 33b form, and carriage 33 just can move to the length direction of guide plate 11b along slotted hole 11e.And, thus, just can adjust the position of the circumferencial direction that stores rotating cylinder 19 of weft yarn clamping device 30 (card shotpin 31).
Again, occasion in this structure, because card shotpin 31 stores rotating cylinder 19 relatively and can carry out the position adjustment independently, change so should will store the position of circumferencial direction of the rotating cylinder sheet 19a of rotating cylinder 19 with the change of position of card shotpin 31 accordingly, the patchhole 19b that must be adjusted to the rotating cylinder sheet is in the position relative with blocking shotpin 31.
Position for this rotating cylinder sheet 19a is adjusted, as previously mentioned, the fixed disc 15 of supporting rotating cylinder sheet 19a, owing to can be rotated by relative rotation axi 13, utilize the sucking action of permanent magnet 15a and 18a can keep the rotatable phase of relative fixed cover 11, so by effect the power bigger than the attraction of this permanent magnet is arranged, fixed disc 15 is rotated.Therefore,, fixed disc 15 is rotated to the direction identical with it, can makes the rotating cylinder sheet 19a that is formed with patchhole 19b relative with card shotpin 31 once more by the operator with corresponding to the adjustment of the position of the circumferencial direction that blocks shotpin 31.
But, adjust because the position of rotation of fixed disc 15 is 1 spacing units with permanent magnet, thus the position of blocking shotpin 31 and the position of the patchhole 19b of rotating cylinder sheet 19 can produce may not be consistent situation.This occasion, the same structure of use and Fig. 1,2 embodiment promptly, use the slotted hole 18c that is formed on the magnetic shell 18 and the structure of screw member 11a, make magnetic shell 18 carry out some rotations, it is just passable that the card shotpin 31 and the deviation of patchhole 19 are carried out inching.
As the structure that the position energy that makes weft yarn clamping device 30 (card shotpin 31) changes along the circumferencial direction that stores rotating cylinder 19, except that above structure, also consider to have the structure of record among Fig. 7,8.Again, the structure of record among Fig. 7,8, all same with Fig. 1,2 embodiment, be that weft yarn clamping device 30 is bearing in structure on the magnetic shell 18, and in this record, the structure of weft yarn clamping device and supporting thereof done omission.
In Fig. 7,8 structure, magnetic shell 18 all is the inboard that is embedded in the leading section 11f of fixed cover 11 with its outer peripheral face 18d, is rotated slidably along the inner peripheral surface of its leading section 11f.
And, in the structure of Fig. 7,, be provided with both the pushing fixed component 34 of leading section butt with fixed cover 11 and magnetic shell 18 as the prevention whirligig of the magnetic shell 18d of relative fixed cover 11.This pushes fixed component 34, utilizes screw member 34a to be fixed on the front end face 11g of fixed cover 11, and by with the front end face 18e butt of magnetic shell 18, screw member 34a is carried out fastening, constituted the state that this front end face 18e is pushed.Therefore, in the structure of this Fig. 7, by carrying out fastening to screw member 34a, prevention fixed cover 11 and magnetic shell 18 counterrotating states have been constituted, again, by screw member 34a is unclamped, become fixed cover 11 and the counterrotating state of magnetic shell 18 energy, just can adjust the rotatable phase of magnetic shell 18 relative fixed covers 11.
Again, in the structure of Fig. 8, as the prevention whirligig of magnetic shell 18d relative fixed cover 11, be provided with the limit screw 35 on the leading section 11f that spiral shell is inserted in fixed cover 11, this limit screw 35 is by screwing in the outer peripheral face 18d butt of its leading section and magnetic shell 18.Therefore, in the structure of this Fig. 8, by limit screw 35 is screwed in, the outer peripheral face 18d crimping of the leading section of limit screw 35 and magnetic shell 18 thus, becomes prevention fixed cover 11 and magnetic shell 18 counterrotating states, again, make fixed cover 11 and the magnetic shell 18 can counterrotating state by limit screw 35 being retreated, becoming, just can adjust the rotatable phase of magnetic shell 18 relative fixed covers 11.
Again, the present invention also is not limited to each above-mentioned example, only otherwise break away from aim of the present invention and can carry out various changes.
