Hook 63,64 and 65 lays respectively at fixed blade 60, the preceding end portion of removable blade 61 and yarn clamping disk 62.Outer surface at hook 63 forms a blade 63a, at the inner surface formation blade 64a of hook 64.Fixed blade 60 and yarn clamping disk 62 are supported on the bar 66,67 and 68 that extends between side panel 7 and guide rod 27 and 28.Removable blade 61 is provided with the groove 69 and 70 that the lateral separation distributes.Guide rod 27 and 28 just is engaged with in groove 69 and 70, and thus, movably blade 61 can laterally move on guide rod 27 and 28.Removable blade 61 links to each other with pin 71.Pin 71 is positioned at the upper groove 35 of lever jack 17.When lever jack 17 moves to the right, as shown in Figure 1, the rear wall 35a of upper groove 35 engages with pin 71, and removable blade 61 is moved to the right.
To explain the running of the yarn feeder among the present invention below.When yarn feeder 1 was in off working state, the selective lever 4 that is upwards promoted by spring 22 and selector projection 16 was remained on the upper of them respectively, as shown in Figure 1.Lever jack 17 is returned to and returns the position, is upwards promoted by spring 32, and thus, lower lobes 36 is withdrawn into the inside of yarn feeder 1.Executing agency 25 moves along a large amount of yarn feeder circular arrangement.When executing agency 25 engages with yarn feeder 1, wherein treat to be fed, be rotated with the rocking pin 26 of the selector projection 16 corresponding executing agencies 25 of the lever jack 17 corresponding selective levers 4 that are used for guiding selected yarn and press down selector projection 16 by the one thread that yarn feeder feeds.Then, selective lever 4 clockwise rotates, as shown in Figure 1, the terminal 4a in back is moved downward, and the terminal 4a in back contacts and presses down the upper lobes 18 of lever jack 17, makes the elastic force rotation of lever jack 17 antagonistic springs 32, thus, lower lobes 36 is stretched out downwards from yarn feeder 1, enters in the path that advances cam 51, as shown in Figure 2.Retaining mechanism 40 maintains the back terminal 4a of selective lever 4, contacts with the upper lobes 18 of lever jack 17, as shown in Figure 2; In the instantaneous cycle before lever jack 17 begins to enter the time point of yarn feeding position, in the path that advances cam, retaining mechanism 40 maintains the lower lobes 36 of lever jack 16.Begin to enter at lever jack 17 before the time point of yarn feeding position during be meant that lever jack 17 begins to enter the time durations before the time point of yarn feeding position.
Therefore, begin to enter at lever jack 17 before the time point of yarn feeding position during, retaining mechanism 40 keeps the lower lobes 36 of lever jacks 17 in the path that advances cam 51.Therefore, although executing agency's 25 work in short time only can be guaranteed in the lower lobes 36 of lever jack 17 and advance suitable movement relation between the cam 51.Thereby the joint between the lower lobes 36 of lever jack 17 and the propelling cam 51 can be by timing correctly.
When the lower lobes 36 of lever jack 17 remains in the path that advances cam by retaining mechanism 40, lower lobes 36 is moved along the cam face 51a that advances cam 51, thus, lever jack 17 is moved to the left, as shown in Figure 2, move to position shown in Figure 3 from position shown in Figure 2, in this position, the bottom of V-arrangement guide groove 30 fully cooperates with guide rod 28.Therefore, thread guide eyelet 53 moves on level and vertical direction, and moves past the top of the pin 2 that remains on the cylinder 3.
When the lower lobes 36 of lever jack 17 arrived position near the top that advances cam 51, the rear wall 35a of the upper groove 35 of lever jack 17 contacted with the nose of locking element 44 protruding 45, and as shown in Figure 4, promotion locking element 44 clockwise rotates.When the lower lobes 36 of lever jack 17 arrives the position at the top that advances cam 51, arrived front position by the lever jack 17 of guide rod 27 and 28 guiding, lever jack 17 is on guide rod 28, because the elastic force of spring 32 is rotated counterclockwise, as shown in Figure 5.Thereby guide rod 27 engages with the lower end of M shape guide groove 29, and lower lobes 36 returns to the inside of yarn feeder 1.
Simultaneously, the thread guide eyelet 53 that forms in the preceding end portion of lever jack 17 is reduced to the yarn feeding position slightly, thread feed pin 2.When lever jack 17 advances, push away pin 71 with the contacted removable blade 61 of rear wall 35a of the upper groove 35 of lever jack 17 forward so that promote removable blade 61.Thereby, remain on fixed blade 60 hook 63 and 65 and yarn holding tray 62 between the hook 64 with fovea superior U-shaped blade 64a of removable blade 61 protract and exceed hook 63 and 65.When yarns Y was fed to pin and inweaved in the knitwear, yarns Y did not enter the hook 64 that has U-shaped blade 64a.
After the row that imports predetermined quantity by lever jack 17 was inweaved, yarns Y just was transformed another one thread.Yarn feeder 1 just stops to feed first one thread, begins to feed second one thread.Suitable timing controlled is carried out in executing agency's 25 runnings, the feeding that begins that stops to feed with second one thread of first one thread is carried out simultaneously.In any case, first and second one thread are all fed for some burr.Because the running of executing agency 25 is to carry out in one very short period, therefore, after the selector projection 16 of selective lever 4 was pressed down a very short time, selector 4 just was returned to original position rapidly.
The stopping of first one thread feeding undertaken by following steps.Selector projection 16 execution that have the selective lever 4 of rocking pin 26 when 25 pairs of executing agencies press down, and first one thread is in the feeding state, and as shown in Figure 5, selective lever 4 is clockwise rotated, and intermediate projections 19 presses down the upper lobes 18 of lever jack 17, as shown in Figure 5.Because 25 one very short periods of running of executing agency, 16 of the selector projectioies of selective lever 4 are depressed very short time, selector 4 is just because the elastic force of spring 22 is returned to original position rapidly.When the upper lobes 18 of lever jack 17 was pressed down by the intermediate projections of selective lever 4, lever jack 17 turned clockwise on guide rod 28, discharges the nose protruding 45 of locking element 44 from the rear wall 35a of upper groove 35.Then, locking element 44 is owing to spring 47 rotates counterclockwise, and the flush end 46 of locking element 44 contacts with the shoulder 18a of last pad 18.Thereby the elastic force of lever jack 17 antagonistic springs 32 is maintained at the yarn feeding position, and lower lobes 36 is stretched out downwards from yarn feeder 1 simultaneously.
Therefore, the lever jack 17 that imports first one thread turns clockwise on guide rail 28, and the lower lobes 36 of lever jack 17 is stretched out downwards from yarn feeder 1, as shown in Figure 6.
As shown in Figure 6, before lever jack 17 begins to reply from the yarn feeding position during in retaining mechanism 40 maintain lever jack 17 in the yarn feeding position, in this yarn feeding position, the lower lobes 36 of lever jack 17 is positioned on the path of propelling cam 51.Be to comprise that lever jack begins the time durations of the time point before the withdrawal of yarn feeding position during before lever jack 17 begins time point when reply the yarn feeding position.
Because, in during very short before lever jack 17 begins to reply from the yarn feeding position, locking element 40 keeps lever jack 17 in the yarn feeding position, lower lobes 36 at this yarn feeding position lever jack 17 is positioned on the path that advances cam 51, can guarantee in the lower lobes 36 of lever jack 17 and the suitable movement relation between the propelling cam 51.Thereby the joint between the lower lobes 36 of lever jack 17 and the propelling cam 51 can be by correct timing.
The lower lobes 36a that imports the lever jack 17 of first one thread engages with answer cam 52.Reply cam 52 promotion lever jacks 17 and do return motion.Then, the convex shoulder 18a of upper lobes 18 moves to the right, and as shown in Figure 6, convex shoulder 18a is released from nose protruding 45, and the flush end 46f and the thread-guide element of locking element 44 are unlocked.Because lever jack 27 engages with M shape guide groove 29, the lower lobes 36 of lever jack 17 keeps down from yarn feeder 1 and stretches out the position of combination in lever jack 17 is returned to the preceding groove 29a of preceding end that guide rod 27 enters M shape guide groove 29.When protruding 36a breaks away from from returning cam 52, lever jack 17 is rotating counterclockwise on guide rod 28 under the impetus of spring 32.And then, locating slot 34 rises, and guide rod 27 engages in the preceding groove 29a of the preceding end of M shape guide groove 29, and the back end of lever jack 17 upwards rotates, in the lower lobes 36a withdrawal yarn feeder 1, as shown in Figure 1.
When lever jack 17 is replied, the front side wall 35b of the groove 35 of lever jack 17 contacts with the pin 71 of removable blade 61, at this moment, its hook 64 is highlighted above fixed blade 60 and yarn holding tray 62, makes removable blade 61 be replied with lever jack 17 and replys the samely.When lever jack 17 arrived its front side wall 35b with position that the pin of removable blade 61 combines, the thread guide eyelet 53 of lever jack 17 was consistent with the hook 64 of removable blade 61, and first one thread by thread guide eyelet 53 is imported into hook 64.When lever jack 17 further bounces back, removable blade 61 also retreats.And then, the be fixed blade 63a of blade 60 and removable blade 61 and 64a of first one thread cuts off, and simultaneously, the end of first one thread is maintained between the hook 64 and 65 of removable blade 61 and yarn holding tray 62.
To describe below, first and second one thread are used simultaneously in burr and inweave the situation of stringer.Even, select the lever jack 17 of first of the importing and second one thread respectively by the rocking pin 26 that encourages the executing agency 25 that controls selective lever 4 simultaneously, the lower lobes 36 of the lever jack 17 that imports second one thread and the lower lobes 36a of the lever jack 17 that imports first one thread are stretched out in yarn feeder 1, consider the rotation direction of knitting machine, propelling cam 51 before returning cam 52, at first the lower lobes 36 with the lever jack that imports second one thread meshes, promotion lower lobes 36 is advanced along the surperficial 51a of cam, and when bottom projection 36 arrives the top that advances cam 51, in the lower lobes 36 withdrawal yarn feeders 1, therefore, lower lobes 36 can not engage with the cam 52 that returns that is positioned at propelling cam 51 rear portions.Subsequently, return the lower lobes 36a engagement of the lever jack 17 of cam 52 and guiding first yarn.Therefore, first and second one threads fed with distance L shown in Figure 7 corresponding during.
Yarn feeder among the present invention can transmit the transient motion of executing agency, and for example, a selecting arrangement pins lever jack by locking device.Therefore, lever jack can be accurately controlled, and random motion can not take place, thereby, avoid knitting machine in operation process, to break down.Because the removable blade of cutting blade is directly driven by lever jack, guide motion and yarn cut off motion can carry out fully synchronously, without any need for the additional mechanism providing additional operation of operation cutting blade.
Because, retaining mechanism can tightly keep by the selected lever jack of the selective lever of actuating mechanism controls, this lever jack is advanced to the yarn feeding position, so, the lower lobes of lever jack can be positioned at and advance cam on the trajectory of yarn feeding position, after the action of executing agency was finished, the selected lever jack of snap action that is performed mechanism remained on selected state.When stopping by selected lever jack yarn feeding and beginning to feed another one thread by another selected lever jack, selected lever jack can be maintained at selected state.
Yarn supply system among the present invention comprises single device for selection controlling, and for example executing agency selects operating means to move along a large amount of yarn feeders.Therefore, no matter the quantity of yarn feeder what, Yarn supply system needs single selector operating means.Independently the use of selector operating means can be simplified the structure of knitting machine, maintains easily work.
Because the removable blade of cutting blade and thread-guide element interlocking are so when thread-guide element bounces back from the yarn feeding position, thereby removable blade can be moved the cut-out yarn by thread-guide element, no longer needs the special entity of any mobile removable blade.
