Selecting mechanism 20a comprises needle selection actuator 24.Needle selection actuator 24 is equipped on the needle selection plate 13 of balladeur train 11, and adsorption plane 24a is arranged on the surface in the face of needle-bar 2 sides.In case adsorbed state is disengaged, in order to leave the state of adsorption plane 24a from the armature 19d of selection piece 19, make the head of armature 19d reset into adsorbed state near adsorption plane 24a side, also be equipped with by carriage 25 at balladeur train 11 and restore and branch's triangle 26.Restore and branch's triangle 26, make it to float from the bottom surface side pushing selection piece 19 of needle tray 5, reset into adsorbed state, then, according to the needle selection results direct to different paths.At selection piece 19, in order to accept to restore and the effect of branch's triangle 26, also to be provided with the projection 19g of branch that erects setting towards the outstanding mode of the bottom surface side of needle tray 5.
Remove armature 19d to the adsorbed state of adsorption plane 24a the time, front end to balladeur train 11 lateral bends of elastic foot sheet 19c, in balladeur train 11 sides, the triangular facet butt with the fulcrum of spring triangle 27 of the front side that is arranged on adsorption plane 24a becomes the fulcrum of spring of accepting elastic force.In addition, in adsorbed state, the tail end 19f of the matrix 19a of selection piece 19 is in balladeur train 11 sides, and is arranged on than adsorption plane 24a more by the surperficial butt of the fulcrum plate 28 of tail end-side.For matrix 19a, at the bottom surface side of needle tray 5, be provided with the supporting point part 29 that connects the wire etc. of needle plate 4 in the direction vertical with paper.In release conditions such shown in the accompanying drawing, the 19h of the pivoting support section butt of supporting point part 29 and matrix 19a.Have again, be arranged at triangle device 20b that the needle selection of balladeur train 11 sides uses and comprise and restoring and branch's triangle 26, fulcrum of spring triangle 27, fulcrum plate 28, and needle selecting cam 30.Have again, near selection piece 19, with supporting point part 29, also have the metal tape 4a, the wire 4b that connect needle plate 4 in the direction vertical with paper.Metal tape 4a, at the triangular facet of fulcrum of spring triangle 27, in the position of the front end that does not push elastic foot sheet 19c, the upper surface of pushing elastic foot sheet 19c, the face side ground that elastic foot sheet 19c does not excessively float needle tray 5 limits.Wire 4b, the mode of excessively not floating in needle tray 5 with slyder 8 limits.
Shown in Fig. 2 (a), when armature 19d was in adsorbed state at adsorption plane 24a, the 19h of pivoting support section of the lower surface of matrix 19a left supporting point part 29.In addition, also separate between the lower surface of the upper surface of elastic foot sheet 19c and metal tape 4a.From matrix 19a call in person downside that 19b erects the base portion of setting of sheet is formed and avoids the shape that contacts with wire 4b.In addition, the lower surface of leading section 19e leaves the upper surface of slyder 8, and therefore, the supporting of selection piece 19 does not exist with ... needle-bar 2 sides.With the head of the armature 19d of adsorption plane 24a butt, with the tail end 19f of the surperficial butt of fulcrum plate 28, and and the front end of the elastic foot sheet 19c of the triangular facet butt of fulcrum of spring triangle 27, stably carry out the supporting from the selection piece 19 of balladeur train 11 sides.At this moment, the position of the surperficial butt of tail end 19f and fulcrum plate 28 becomes fulcrum.In the absorption affinity of armature 19d effect to adsorption plane 24a.At the front end of elastic foot sheet 19c, effect is from the elastic force of the triangular facet of fulcrum of spring triangle 27.So-called this absorption affinity and elastic force refer to and will arrive the rightabout moment of the butt position of fulcrum plate 28 as fulcrum.Even balladeur train 11 walkings, the moment that is produced by elastic force is not subjected to the impact of the change at the interval between needle selection plate 13 and needle-bar 2 yet, thereby stablizes.By the moment that absorption affinity produces, because the energising to needle selection actuator 24 reduces, if less than the moment that is produced by elastic force, then the matrix 19a of selection piece 19 turns round as fulcrum to the butt position of fulcrum plate 28 with tail end 19f.Have again, and can to reduce the off-position of armature 19d of absorption affinity corresponding because of energising, with regard to the recovery and branch's triangle 26 of the projection 19g of branch side, as described later, avoid the head of the projection 19g of branch.Rotating direction becomes the direction that armature 19d leaves adsorption plane 24a, that is, the clockwise direction of accompanying drawing, armature 19d are removed the adsorbed state of adsorption plane 24a is released.The moment of the direction of the absorption that releasing is produced by the elastic force of elastic foot sheet 19c in adsorbed state stably acts on, and therefore, also can stably carry out with the action that needle selection actuator 24 is removed adsorbed state.
Distance between the position of the front end of tail end 19f and elastic foot sheet 19c and the triangular facet butt of fulcrum of spring triangle 27 is larger than the distance between the absorption position of adsorption plane 24a of the tail end 19f of the matrix 19a that becomes fulcrum and armature 19d.Thus, as the moment that tail end 19f is made as fulcrum, the moment that can relatively utilize significantly the elastic force by elastic foot sheet 19c to produce.In the formation of as shown in Figure 8 selection piece 9, the distance that abutment portion 13b and armature 9b are adsorbed to distance between the position of needle selection actuator 14 and become than front end between the fulcrum of spring 8c of front end of the abutment portion 13b of sheet heel 9f of revolution fulcrum and elastic foot sheet 9c is large.Thereby, the moment that is merely able to utilize the elastic force by elastic foot sheet 9c to produce relatively littlely.
Adsorbed state shown in Fig. 2 (a), if the releasing by adsorbed state, matrix 19a around with the fulcrum revolution of the tail end 19f of fulcrum plate 28 butts, the then 19h of pivoting support section of the mid portion of matrix 19a and supporting point part 29 butts.As after expression among Fig. 2 (b) has just been removed adsorbed state, if the 19h of pivoting support section and supporting point part 29 butts, then the 19h of pivoting support section becomes new fulcrum, and matrix 19a is to the counter clockwise direction revolution around this fulcrum, and the front end of tail end 19f leaves the surface of fulcrum plate 28.The base portion of sheet heel 19b is in the front of the 19h of pivoting support section, and therefore by anticlockwise revolution, the head of sheet heel 19b is outstanding from needle tray 5.The front end of elastic foot sheet 19d continues the butt to the triangular facet of the fulcrum triangle 27 of balladeur train 11 sides, and therefore, the selection piece 19 of release conditions is supported from balladeur train 11 sides and needle-bar 2 sides two sides.With restoring and branch's triangle 26 mechanically carries out recovery from from release conditions to adsorbed state reliably, therefore, even be accompanied by the walking and the change of the interval between the needle-bar 2 of balladeur train 11, needle selection moves can not become unstable yet.
Fig. 3 represents from the formation of the selection piece 19 that uses the needle selecting device 20 of Fig. 1 of seeing as the right side side of horizontal volume machine 17.Selection piece 19 more is being provided with armature 19i by the position of tail end 19f than armature 19d, makes the position of armature 19d, 19i different.By the different selection piece 19 in the position of alternatively using armature 19d, 19i, thereby even when disposing knitting needle 6 thick and fast, also can carry out reliably the needle selection of each knitting needle 6.
Have again, the position of armature 19i, more being close to than the position of armature 19d becomes the tail end of fulcrum 19f under adsorbed state.Thus, the effect of the elastic force that the front end of elastic foot sheet 19c is subject to as fulcrum of spring is compared with the position of armature 19d and is become large, with regard to identical absorption affinity, continues adsorbed state and becomes difficulty.Therefore, for armature 19i, the length L i that is adjusted into the front end that will contact with adsorption plane arranges longlyer than the length L d of the front end of armature 19d, increases absorption affinity.
Fig. 4 represents the formation of the cam mechanism in the balladeur train 11 of the horizontal volume machine 17 that is used in Fig. 1 and selecting mechanism and does contrast in the formation of the knitting needle 6 shown in the right flank.The adsorption plane 24a of needle selection actuator 24 is divided into the adsorption plane 24d of armature 19d of absorption selection piece 19 and the adsorption plane 24i of absorption absorption armature 19i shown in Figure 3.In fact, will have the unit of the adsorption plane of the single armature of absorption, secondary is arranged ground and is formed needle selection actuator 24.Even the position of armature has three when above, as long as arrange the unit of corresponding quantity.
For two adsorption plane 24d, 24i, with respect to the direction of travel at the balladeur train 11 shown in the left and right directions of accompanying drawing, set identical off-position 24b, 24c.If the time that off-position 24b, 24c and armature 19d, 19i are passed through consistently makes the electromagnetism absorption affinity weaken, then can remove armature 19d, 19i is with respect to the adsorbed state of adsorption plane 24d, 24i and be released.
Have, in the needle selection actuator 24 in the left side of accompanying drawing, at the downside of needle selection actuator 24, accordingly expression is restored and the triangular facet of branch's triangle 26 again.Recovery and branch's triangle 26 are applied to the projection 19g of branch of selection piece 19.If the head of the projection 19g of the branch bottom surface side from needle tray 5 is floated, armature 19d, 19i that releasing because of adsorbed state has been released contact with adsorption plane 24d, 24i again, reset into adsorbed state.In addition, accordingly the projection 19g of branch of selection piece 19 is directed to different paths from the off-position 24b, the 24c that remove adsorbed state.In addition, in the fulcrum of spring triangle 27 of the front that is arranged at adsorption plane 24a, the mode that elastic force is increased with the amount of deflection that increases elastic foot sheet 19c, by the front end that pushes the elastic foot sheet 19c of selection piece 19 from needle-bar 2 side-prominent triangular facet 27a, armature 19d, 19i are released easily.
In the needle selection plate 13 of balladeur train 11, at the front configuration needle selecting cam 30 of needle selection actuator 24.Needle selecting cam 30 by being branched off into different paths because of the effect to the projection 18g of branch of restoring and branch's triangle 26 produces, is applied to from the call in person head of 19b of the sheet of the outstanding selection piece 19 of needle tray 5.Needle selection actuator 24 devices spaced apart ground on the direction of travel of balladeur train 11 has two off-position 24b, 24c that can remove the adsorbed state of armature 19d, 19i.Restore and branch's triangle 26 and needle selecting cam 30 by combination, can be corresponding with two off-position 24b, 24c of the adsorbed state of removing armature 19d, 19i, be divided into two different paths 31,32 ground guide plate heel 19b.
Balladeur train 11 goes and back running, therefore, and cam mechanism, the configuration of selecting mechanism left and right symmetrically.For example, if when supposition balladeur train 11 was walked to the right side of accompanying drawing, then knitting needle 6 was with respect to balladeur train 11, relatively the left to accompanying drawing moves.Be arranged at the armature 19d of selection piece 19 of the tail end-side of knitting needle 6, be adsorbed to adsorption plane 24d, arrive off-position 24b.If discharge armature 19d at off-position 24b, then with based on restore and branch's triangle 26 in the branch of guiding of the projection 19g of branch continuous, sheet heel 19b enters in 31 ground, path of needle selecting cam 30 and is directed.Forwards give prominence to the peak shape in path 31, and therefore, the leading section 19e of selection piece 19 goes out slyder 8 to 18 thrusters of tooth mouth.Via until the release at the top of the peak shape in path 31, make the sheet heel 8a of slyder 8 debouch the needle selection position of A position.If do not discharge armature 19d at off-position 24b, discharge armature 19d at off-position 24c, then with based on restore and the branch of the guiding of the projection 19g of branch of branch's triangle 26 continuous, 32 ground, path that sheet heel 19b enters into needle selecting cam 30 are directed.Selection piece 19 goes out slyder 8 at leading section 19e to 18 thrusters of tooth mouth, the top in the path 32 of peak shape makes the sheet heel 8a of slyder 8 debouch the needle selection position of H position.If armature 19d does not discharge at arbitrary off-position 24b, 24c, continue the absorption to adsorption plane 24d, then the sheet of slyder 8 heel 8a keeps the needle selection position of B position.
The sheet heel 8a of slyder 8 by the set square 12 of balladeur train 11, is directed into the zone that is provided with B compressing tablet 33, H compressing tablet 34 of the scope that is provided with the triangle device 12a that weaves into driving that carries out knitting needle 6.B compressing tablet 33 is fixed compressing tablets, is applied to the sheet heel 8a of B position, and the sheet 8a that calls in person is pressed in the needle tray 5.Accordingly, the sheet of needle jack 7 heel 7a also is absorbed in the needle tray 5, no longer is subject to weaving into the effect of triangle 35, and the hook 21a of knitting needle 6 does not debouch tooth mouth 18 and stays needle-bar 2 sides, becomes the action of the water wing that does not carry out coil formation.H compressing tablet 34 is for example to be divided into three partly configurations, and swings respectively, can keep out of the way until with the movable compressing tablet of the position shown in two dot dot dash.Even the H compressing tablet 34 of the state of not keeping out of the way is also same with B compressing tablet 33, the sheet of slyder 8 heel 8a is pressed in the needle tray 5, knitting needle 6 carries out the action of tuck, barring-on.At sheet heel 8a during by the A position, owing to do not dispose compressing tablet, therefore, sheet heel 7a keeps from the outstanding state of needle tray 5, accepts the driving that produces by weaving into triangle 35, the action that knitting needle 6 weaves.
In the front of weaving into triangle 35, configuration is applied to the sheet heel 7c of needle jack 7 and the transfer cam 36 that drives on the action ground that knitting needle 6 carries out being associated with barring-on.Weave into triangle 35 about configuration make the sheet heel 8a of slyder 8 turn back to the guide triangular 37 of B position.
Have again, be provided with two off-position 24b, 24c at adsorption plane 24a, be provided with corresponding path 31,32 at needle selecting cam 30, carry out to the A position or the switching of H position, if but the quantity of increase off-position 24b, 24c, and correspondingly increase path 31,32 quantity, then can enough needle selecting devices carry out a plurality of actions and switch.
Fig. 5 represents from right side side and the formation of the major part of the needle selecting device 20 of Fig. 1 that the front is seen.Fig. 6 represents respectively needle selection actuator 24, the recovery of seeing from the top and the branch's triangle 26 of Fig. 5 of seeing from the below.Such shown in Fig. 5 (a), on needle selection actuator 24, near adsorption plane 24a ground mounting spring fulcrum triangle 27 and fulcrum plate 28, and by the installation recovery of carriage 25 devices spaced apart ground and branch's triangle 26.
Like that, restoring and branch's triangle 26 shown in Fig. 5 (b), central authorities be provided with protuberance 26a, about be provided with recess 26b, 26c.In right side and the left side of recess 26b, 26c, be respectively equipped with the inclined plane 26d, the 26e that link to each other with the height of protuberance 26a.For example, in the 26e of inclined plane, under the butt state to the head of the projection 19g of branch of selection piece 19, can shown in path 39, like that upwards push away, armature 19d, 19i are contacted with adsorption plane 24a, reset into adsorbed state.Inclined plane 26d also has same function.Recess 26b, 26c when armature 19d, 19i discharge from adsorption plane 24a, can accept in branch projection 19g side branch's guiding function of recovery and branch's triangle 26, therefore become the section that dodges (escaping Ga) with respect to the head of the projection 19g of branch.Recess 26b, 26c have the certain height lower than protuberance 26a, are respectively equipped with more rake 26f, the 26g of step-down in the end.
In addition, like that, fulcrum of spring triangle 27 has inclined plane 27b, 27c in the both sides of triangular facet 27a shown in Fig. 5 (b).In the state of the front end of the elastic foot sheet 19c of selection piece and inclined plane 27b, 27c butt, the elastic force that is applied to fulcrum of spring triangle 27 dies down.This resilient force is on the direction that armature 19d, 19i are discharged from adsorption plane 24d, 24r.Begin to enter into when disposing needle selection actuator 24 regional at selection piece 19, the front end of elastic foot sheet 19c, backward smooth triangular facet 27a divides a word with a hyphen at the end of a line with inclined plane 27b, the 27c butt of fulcrum of spring triangle 27.Thereby, be applied to armature 19d, the elastic force of the elastic foot sheet 19c of adsorption plane 24d, the 24i of 19i, can set for, the state that does not roughly act on to the butt position movement of fulcrum of spring triangle 27 time, increase gradually along inclined plane 27b, 27c, continue effectively state of the largest ground at triangular facet 27a.
Such shown in Fig. 6 (a), from near the inclined plane 27b of fulcrum of spring triangle 27, the 27c two ends, begin to have adsorption plane 24d, 24i, therefore under the state that the elastic force from elastic foot sheet 19c does not roughly act on, armature 19d, 19i can be adsorbed onto adsorption plane 24d, 24i reliably.In addition, by triangular facet 27a pushing, become the largest ground effectively under the state from the elastic force of elastic foot sheet 19c, armature 19d, 19i reach off-position 24b, 24c, and therefore, the releasing by electromagnetism absorption can discharge reliably.
Such shown in Fig. 6 (b), in recovery and branch's triangle 26, if the head of the projection 19g of branch of selection piece 19 39 is upwards pushed away along the path, after making armature 19d, 19i reset into adsorbed state, remove adsorbed state at any off-position 24b, 24c, then can make the projection 19g of branch drop into recess 26b, 26c, be branched off into respectively path 39A, 39H.At recess 26b, 26c, the projection 19g of branch is trapped in the bottom surface side of needle tray 5, and therefore, the time advance of supporting point part 29 and the 19h of pivoting support section butt can make sheet heel 19b promptly side-prominent to needle selecting cam 30.Path 39H passes rake 26f, therefore, the head of the projection 19g of branch is absorbed in further, can make the outstanding time advance of sheet heel 19b.If remove adsorbed state at off-position 24b, 24c, then pass the path 39B in the prolongation in path 39.Path 39A, 39H under the 11 side-prominent states, guide to respectively the path 31,32 of needle selecting cam 30 shown in Figure 4 from needle tray 5 to balladeur train at the sheet heel 19b that makes selection piece 19.
Have again, if strengthen in the absorption affinity of adsorption plane 24d, 24i and use large-scale and powerful permanent magnet, then the releasing at the adsorbed state of off-position 24b, 24c also needs large-scale and powerful electromagnet.In order to make 24 miniaturizations of needle selection actuator, preferably when non-needle selection on the direction of the magnetic flux of reinforcement permanent magnet with the electromagnet energising, when needle selection, carry out driving at the two poles of the earth that the direction of the magnetic flux of eliminating permanent magnet is switched on.
In addition, as the knitting needle 6 of Fig. 1, use the latch needles that is opened and closed hook 21a by tongue 21b, but also can use the compound needle that is opened and closed hook by pusher jack (ス ラ イ ダ).
Fig. 7 simplifies the formation of its major part of ground expression for the needle selecting device 40 as embodiments of the invention 2.In embodiment 2, will restore and branch's triangle 26 is configured in the face side of needle tray 5, that is, be configured in balladeur train 11 sides.Needle selection actuator 44 is configured in the bottom surface side of needle tray 5 by carriage 45.Fulcrum of spring triangle 27 and fulcrum plate 28 at the bottom surface side of needle tray 5, are configured in respectively front and the tail end-side of the adsorption plane 44a of needle selection actuator 44.Selection piece 49 has matrix 49a, sheet heel 49b, the 49c of elasticity foot, armature 49d, leading section 49e, tail end 49f, the projection 49g of branch and the 49h of pivoting support section.The function of these each several parts, the corresponding part with selection piece 19 is equal basically.Wherein, the outstanding direction of the front end of the 49c of elasticity foot and armature 49d is the bottom surface side of needle tray 5, and is different from selection piece 19.In addition, the outstanding direction of the projection 49g of branch becomes the face side of needle tray 5, and is different from selection piece 19.In addition, the 49h of pivoting support section also is arranged on the upper face side of matrix 49a, under the adsorbed state of selection piece 49, leaves support unit 29.Under adsorbed state, selection piece 49 is same with selection piece 19, also leaves the metal tape 4a, the wire 4b that connect needle plate 4.In addition, the following side of the leading section 49e of selection piece 49 is separated with the upper face side of slyder 8.Thereby the selection piece 49 of adsorbed state does not exist with ... the needle-bar side, only exists with ... balladeur train 11, even stably be supported when balladeur train 11 walking yet.
Accompanying drawing represents the adsorbed state of selection piece 49.Based on armature 49d to the absorption affinity of adsorption plane 44a, will be to the abutment portion of the tail end 49f of fulcrum plate 28 moment as fulcrum, larger than the moment of the spring reaction power of accepting from the surface of fulcrum of spring triangle 27 based on the front end of the 49c of elasticity foot.Under the state of the head of being avoided the projection 49g of branch by recovery and branch's triangle 26, if based on the absorption affinity of adsorption plane 44a is reduced and the torque ratio of the absorption affinity of armature 49d take tail end 49f as fulcrum little based on the moment in the spring reaction power of fulcrum triangle 27, then absorption is disengaged, and armature 49d leaves adsorption plane 44d.Matrix 49a with the part of tail end 49f and fulcrum plate 28 butts as fulcrum, to counterclockwise revolution.If the 49h of pivoting support section and supporting point part 29 butts, then this abutment portion becomes rotating fulcrum, and gyratory directions is to clockwise counter-rotating, and tail end 49f leaves the surface of fulcrum plate 28.Via clockwise revolution, sheet heel 49b is absorbed in, and still, needs only the degree that can accept the guiding of needle selecting cam 30 for head, to balladeur train 11 side-prominent getting final product.In adsorbed state, sheet heel 49b is further outstanding, but as shown in Figure 4, can be on needle selecting cam 30 31,32 downside is provided with the path of the straight line of avoiding sheet heel 49b in the path.
