Technical field
The present invention relates to compare needle selecting system that existing structure more is difficult to produce the flat braiding machine of needle selection mistake, used the flat braiding machine of this needle selecting system and the slide cam selector that consists of the part of needle selecting system.
Background technology
Flat braiding machine has: a pair of needle-bar at least, be disposed at knitting needle in each needle trays of a plurality of needle trays arranged side by side on each needle-bar, along the reciprocating balladeur train of the length direction of needle-bar (with the direction of the bearing of trend quadrature of needle tray).Be equipped with knitting cam at balladeur train, utilize this knitting cam to make knitting needle carry out braid movement (loop transfer between the needle-bar of woollen yarn knitting, tuck, flotation line and front and back).Make each knitting needle carry out what kind of braid movement by utilizing needle selecting system to select knitting needle to decide.As aforesaid needle selecting system, the known needle selecting system (for example with reference to patent documentation 1) that employing electromagnetic needle selection mode is arranged.
Fig. 7 is the key diagram for the needle selecting system of explanation electromagnetic needle selection mode in the past, near the structure the slide cam selector in the cross section of its expression needle-bar.In this Fig. 7, balladeur train 300 is along the reciprocating motion of paper depth direction.When this balladeur train 300 reciprocating motion, be disposed at the knitting needle 201 of needle tray 101 of needle-bar 100 by needle selection, based on this needle selection result, knitting needle 201 is mobile and weave along the bearing of trend (paper left and right directions) of needle tray 101.The needle selecting system of this Fig. 7 is made of each knitting needle 201 slide cam selector 9 that has and the needle selecting device 2T that is arranged at balladeur train 300.
Knitting needle 201 has: have pinhock pin body (omit diagram), make the pin body along the pin heel 7 of the bearing of trend advance and retreat of needle tray 101, to selection needle jack 8 that pin heel 7 advance and retreat are controlled, change needle tray 101 bearing of trend on the slide cam selector 9 of position of selection needle jack 8.According to the position of selecting needle jack 8, the driving that has with stitch 71 and pusher jack with respect to pin heel 7 braidings that have is with the active state change of the knitting cam 30 of stitch (omitting diagram), and the braid movement of knitting needle 201 also changes.
Select needle jack 8 on the bearing of trend of needle tray 101, can be in following three positions (B, H, A) (according to different flat braiding machines, also having the situation that is in two positions).For example, the B position weaves corresponding to flotation line.The H position is the position of more leaning on tooth mouth side (paper right side) than above-mentioned B position, corresponding to tuck knitting or barring-on.The A position is the position of more leaning on tooth mouth side than H position, corresponding to woollen yarn knitting or barring-on.Above-mentioned position is selected needle jack 8 tail end-sides (side opposite with tooth mouth side) and is divided into two strands position maintaining part 82 to keep by being positioned at.Be formed with three recesses in position maintaining part 82, the line 8w that extends along the length direction (paper depth direction) of needle-bar 100 is sticked in each recess, thereby selects the location of needle jack 8.
The slide cam selector 9 that changes the position of above-mentioned selection needle jack 8 has: matrix 91, be arranged at the tooth mouth side of matrix 91 leading section 92, be arranged at the armature 93 of the tail end-side of matrix 91, from the matrix 91 elastic foot sheet 94 that extends of side caudad.In addition, be provided with in the upper end side (square side is in the face side of needle-bar 101 on paper) of armature 93 and rise with stitch 95, be provided with in the upper end side of matrix 91 and descend with stitch 96.By being acted on, needle selecting cam 39 described later rises with stitch 95, slide cam selector 9 is to tooth mouth side shifting, utilize stitch 81 that the leading section 92 of this slide cam selector 9 will select needle jack 8 to the extruding of tooth mouth side, thus make select needle jack 8 from the B position to the H position or the A position movement.After this, slide cam selector 9 turns back to rapidly the B position, prepares next time needle selection.Need to prove that slide cam selector 9 always is in the B position, the rising of slide cam selector 9 is in the state of giving prominence to from needle tray 101 with stitch 95.
On the other hand, needle selecting device 2T has: with each stitch 95 of slide cam selector 9,96 relative needle selecting cams 39, the needle selecting actuator 10 relative with the lower surface (being adsorbed end face 93s) of the armature 93 of slide cam selector 9.Be provided with the adsorption plane 10s that permanet magnet exposes at needle selecting actuator 10, the armature 93(that can adsorb slide cam selector 9 at this adsorption plane 10s is adsorbed end face 93s).At this, on adsorption plane 10s, be set with two at its width (paper depth direction) and break away from the zone, break away from the zone at this, utilize the effect by the electromagnetic force that produces to needle selecting actuator 10 energisings, weaken the magnetic force that is produced by permanet magnet.
Have in the situation that the flat braiding machine of said structure weaves in utilization, if balladeur train is walked so that needle selecting actuator 10 close slide cam selectors 9 at needle-bar 100, state before then expression is adsorbed among armature 93(Fig. 7 of the adsorption plane 10s of needle selecting actuator 10 absorption slide cam selector 9), making rises sinks in the needle tray 101 with stitch 95.This state is so-called non-needle selection state.If to needle selecting actuator 10 energisings, then needle selecting cam 39 can not act on and rise with stitch 95, slide cam selector 9 does not move to tooth mouth side and is maintained at the B position.
Relative therewith, in the frame walking of sliding in state that the armature 93 of slide cam selector 9 is adsorbed, when armature 93 closed on the disengaging zone of adsorption plane 93s, if to needle selecting actuator 10 energisings, then armature 93 broke away from from adsorption plane 10s.So the elastic force of the elastic foot sheet 94 of the position maintaining part 82 upper end butts of utilization and selection needle jack 8 rises and floats from needle tray 101 with stitch 95, becomes needle selecting cam 39 and can act on the needle selection state that stitch 95 is used in this rising.If needle selecting cam 39 acts on the rising stitch 95 of slide cam selector 9, when then slide cam selector 9 is to tooth mouth side shifting, the leading section 92 of slide cam selector 9 will select the rising of needle jack 8 to extrude to tooth mouth side with stitch 81, so select the position of needle jack 8 also to change.In addition, make armature 93 break away from such different situations from adsorption plane 10s according to breaking away from the zones which at two, slide cam selector 9(selects needle jack 8) also thereupon change of position.

As shown in Figure 4, above-mentioned needle selecting actuator 10 is so that its adsorption plane 10s mode relative with the end face of needle-bar 100 is disposed at balladeur train 300.Therefore, if make balladeur train 300 make needle selecting actuator 10 near slide cam selectors 4 to paper depth direction walking, then adsorption plane 10s faces armature 43(Fig. 2 of slide cam selector 4) the upper end namely be adsorbed end face 43s.In addition, the needle selecting device among Fig. 42 is in the position of more leaning on the paper inboard than knitting needle 200.
On the other hand, shown in Fig. 3 (A), (B), (D), the triangle 20 of clamp-oning that consists of needle selecting device 2 is the parts that are installed on needle selecting actuator 10 and shift the position relative with needle selecting actuator 10 onto.This clamp-ons acting as of triangle 20: be squeezed between the armature 43 of slide cam selector 4 and the elastic foot sheet 44 and expand both intervals of 43,44, so that armature 43 is adsorbed on the adsorption plane 10s(of needle selecting actuator 10 with reference to Fig. 5 described later and explanation thereof).In addition, clamp-on triangle 20 also have the elastic foot sheet 44 that has of supporting slide cam selector 4 abutting part 44b so that slide cam selector 4 be in not by the effect (with reference to Fig. 5 described later and explanation thereof) of this state of needle-bar 100 supportings.And, present embodiment clamp-on the effect that triangle 20 also has the needle selecting cam 39 of existing structure shown in Figure 7.
Clamp-on this side in the triangle 20, relative with the adsorption plane 10s of needle selecting actuator 10 above-mentioned, be formed with inclined plane 21, epimere face 22, stage casing face 23 and hypomere face 24.Rise gradually and be connected with epimere face 22 towards pars intermedia from the width end of clamp-oning triangle 20 in the inclined plane 21 of clamp-oning triangle 20.Epimere face 22 is to form the roughly tabular surface of M shape.Stage casing face 23 is towards the pars intermedia tabular surface of the crooked roughly M shape of side (being the paper upside in Fig. 3 (D)) caudad gradually from the width end of clamp-oning triangle 20.Hypomere face 24 is tabular surfaces of chevron roughly.Between stage casing face 23 and hypomere face 24, except the step that forms according to both differences in height of 23,24, be formed with the 20b of wall section.The 20b of wall section only is formed to the position of more leaning on the front than the width pars intermedia of clamp-oning triangle 20, therefore, is formed with the path that drops to hypomere face 24 from stage casing face 23.The height of the 20b of this wall section and the height of epimere face 22 be (with reference to Fig. 3 (A), (B)) about equally.
As mentioned above, be formed with highly different a plurality of 21～24 at the end face of clamp-oning triangle 20.According to the step between above-mentioned 21～24, be formed with three guide path B, H that the rising to slide cam selector 4 guides with stitch 45, A(with the double dot dash line of Fig. 3 (D) and the letter representation of square frame).Each guide path B, H, A correspond respectively to B, H, the A position of slide cam selector 4.That is, the triangle 20 of clamp-oning of present embodiment has concurrently the rising of slide cam selector 4 with the effect of stitch 45 towards the needle selecting cam of tooth mouth side jack-up.
Specify and utilize the needle selecting system 1 with structure described above how to carry out the needle selection of knitting needle 200.
At first, if from the state of Fig. 4 make balladeur train 300 walkings so that needle selecting device 2 near knitting needles 200, then armature 43(Fig. 2 of slide cam selector 4 is clamp-oned in the width end of clamp-oning triangle 20 of needle selecting device 2) and elastic foot sheet 44 between.If balladeur train 300 walks on, then shown in Fig. 5 (A), the inclined plane 21 of clamp-oning triangle 20 contacts with stitch 45 with the rising that is in armature 43 lower ends, clamp-on lower surface 29(Fig. 3 (B) of triangle 20) contact with the abutting part 44b that is in elastic foot sheet 44 upper ends, thus make expansion between armature 43 and the elastic foot sheet 44.Then, rising arrives the epimere face 22 of clamp-oning triangle 20 with stitch 45, and armature 43 is adsorbed by the adsorption plane 10s of needle selection actuator 10.At this moment, the elastic foot sheet 44 of slide cam selector 4 the position of abutting part 44b with clamp-on triangle 20 butts, slide cam selector 4 is supported by balladeur train 300, therefore, even if cause the interval of needle-bar 100 and balladeur train 300 to change minutely along with the walking of balladeur train 300, also be difficult to be subject to the impact of this change based on the absorption of the slide cam selector 4 of adsorption plane 10s.At this moment, be preferably, slide cam selector 4 leaves from line 4w, 5w fully, and slide cam selector 4 is in the state that does not rely on needle-bar 100.In addition, although rising usefulness stitch 45 and epimere face 22 are isolated a little but still are isolated.
At this, even if make slide cam selector 4 be in the state that is not supported by needle-bar 100, because of the vibration that the walking that is accompanied by balladeur train 300 produces balladeur train 300, also probably can make moment act on being adsorbed end face 43s of armature 43 and cause the armature 43 of slide cam selector 4 to break away from from adsorption plane 10s.Relative therewith, in the present embodiment, the abutting part 44b with clamp-oning triangle 20 butts in the elastic foot sheet 44 becomes the fulcrum of spring towards 101 pairs of armature 43 application of forces of needle tray, and this fulcrum of spring (abutting part 44b) is in the position that the formation scope that is adsorbed end face 43s of the armature 43 on the bearing of trend with needle tray 101 repeats, therefore, be difficult to produce moment centered by fulcrum of spring 44b.Therefore, do not use the electromagnetic force of needle selecting actuator 10 to make armature 43 break away from the power effect that this situation need to make certain degree from adsorption plane 10s, under the extent of vibration of the balladeur train 300 that produces in the walking that is accompanied by balladeur train 300, armature 43 can break away from from adsorption plane 10s hardly.
As mentioned above, if armature 43 keeps being adsorbed the state of face 10s absorption and do not break away from, then rise and move at the guide path B shown in Fig. 3 (D) under the state that the epimere face 22 of certainly clamp-oning triangle 20 floats with stitch 45, do not clamp-oned the effect of triangle 20.Consequently, slide cam selector 4 is mobile and keep the B position on the bearing of trend of needle tray 101.In this case, the braid movement of knitting needle 200 becomes the flotation line braiding.
On the other hand, if break away from regional 12a at first of the needle selecting actuator 10 shown in Fig. 3 (D) armature 43 is broken away from, then rise and move at guide path A with stitch 45.Particularly, shown in Fig. 5 (B), rising stitch 45 in that the regional 12a of disengaging is broken away from utilizes the elastic force of the elastic foot sheet 44 that is supported on the lower surface 29 of clamp-oning triangle 20 to be biased towards the bottom of needle tray 101, thus the position of falling the stage casing face 23 of clamp-oning triangle 20.If balladeur train 300 walks on, then shown in Fig. 3 (D), rising is extruded along the guide g1 that is formed by the step between epimere face 22 and the stage casing face 23 to tooth mouth side and falls hypomere face 24 with stitch 45.The rising of falling hypomere face 24 is extruded to tooth mouth side with stitch 45 and then along the guide g2 that is formed by the step between stage casing face 23 and the hypomere face 24, and consequently, slide cam selector 4 arrives the A position as shown in Figure 6.At this, owing between hypomere face 24 and stage casing face 23, be formed with the 20b of wall section, therefore, can not cross guide g2 with stitch 45 and climb on the guide path H because the vibration of balladeur train 300 etc. causes rising.
Then, shown in Fig. 3 (D), broken away from if armature 43 breaks away from regional 12a and breaks away from regional 12b at second by first of needle selecting actuator 10, then rise and move at guide path H with stitch 45.Particularly, rise and fall the stage casing face 23 on the paper right side of clamp-oning triangle 20 with stitch 45, and be extruded to tooth mouth side along the guide g3 that is formed by the step between epimere face 22 and the stage casing face 23.Consequently, slide cam selector 4 arrives the H position.At this, according to being arranged at the 20b of wall section that clamp-ons triangle 20, rising and can excessively not move and climb on the guide path A to tooth mouth side with stitch 45.
In addition, the present invention is not limited to above-mentioned embodiment, can suitably change in the scope that does not break away from purport of the present invention.For example, also can constitute, needle selecting actuator 10 faces slide cam selector 4 and slide cam selector 4 is sunk in the needle tray 101 and is made as non-needle selection state from the bottom surface side of needle-bar 100.In this case, clamp-oning triangle 20, to be configured in the adsorption plane 10s that compares needle selecting actuator 10 more also passable by the position of the top surface side of needle-bar 100.In addition, abutting part 44b in the slide cam selector 4, that clamp-on triangle 20 butts also can be positioned at outside the formation scope that is adsorbed end face 43s of the armature 43 on the bearing of trend of needle tray 101.In addition, the triangle 20 of clamp-oning of present embodiment has the effect of the needle selecting cam of the position that changes slide cam selector 4 concurrently because having guide g1～g3, but also can constitute the triangle of clamp-oning that makes its effect that does not have this needle selecting cam.In this case, need to prepare separately needle selecting cam.
