As shown in Fig. 3 (A), (B), needle selecting device 2 has needle selecting actuator 10 and clamp-ons triangle 20.Wherein, needle selecting actuator 10 can be installed the holding section of clamp-oning triangle 20 except having, and basic structure is identical with needle selecting actuator in the past.Particularly, needle selecting actuator 10 has the adsorption plane 10s of the armature 43 of absorption slide cam selector 4, and this adsorption plane 10s is the face (especially with reference to Fig. 3 (C)) that multiple permanet magnets 11 expose.On this adsorption plane 10s, between the permanet magnet 11,11 of arranging at the width along needle selecting actuator 10 (identical with the direction of travel of balladeur train), be provided with and depart from region 12a, 12b.If to the solenoid energising that is built in needle selecting actuator 10, the magnetic force that departs from region 12a, 12b weakens.
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 selector 4 to paper depth direction walking, adsorption plane 10s faces armature 43(Fig. 2 of slide cam selector 4) upper end be adsorbed end face 43s.In addition, the needle selecting device 2 in Fig. 4 is in more leaning on the position of paper inboard than knitting needle 200.
On the other hand, as shown in Fig. 3 (A), (B), (D), the triangle 20 of clamp-oning that forms 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 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 in do not supported the effect (with reference to Fig. 5 described later and explanation thereof) of this state by needle-bar 100.And, the effect of clamp-oning triangle 20 and also have the needle selecting cam 39 of the existing structure shown in Fig. 7 of present embodiment.
Clamp-on this side in 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.Clamp-oning the inclined plane 21 of triangle 20 rises gradually and is connected with epimere face 22 towards pars intermedia from the width end of clamp-oning triangle 20.Epimere face 22 is to be formed as the roughly tabular surface of M shape.Stage casing face 23 is from clamp-on the width end of triangle 20 towards the tabular surface of the pars intermedia roughly M shape that caudad side (being paper upside) is bending gradually in Fig. 3 (D).Hypomere face 24 is tabular surfaces of chevron roughly.Between stage casing face 23 and hypomere face 24, except the step forming according to both differences in height of 23,24, be formed with the 20b of wall portion.The 20b of wall portion is only formed to the position of more leaning on 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 portion and the height of epimere face 22 roughly equal (with reference to Fig. 3 (A), (B)).
As mentioned above, be formed with highly different multiple 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 of slide cam selector 4 stitch 45 is guided, the double dot dash line of Fig. 3 (D) and the letter representation of square frame for A().Each guide path B, H, A correspond respectively to B, H, the A position of slide cam selector 4., the triangle 20 of clamp-oning of present embodiment has the effect towards the needle selecting cam of tooth mouth side jack-up by the rising of slide cam selector 4 stitch 45 concurrently.
Illustrate and utilize the needle selecting system 1 with structure described above how to carry out the needle selection of knitting needle 200.
First, if from the state of Fig. 4 make balladeur train 300 walk so that needle selecting device 2 near knitting needle 200, 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, as shown in Fig. 5 (A), clamp-oning the inclined plane 21 of triangle 20 contacts with the rising stitch 45 in armature 43 lower ends, clamp-on lower surface 29(Fig. 3 (B) of triangle 20) with contact in the abutting part 44b of elastic foot sheet 44 upper ends, thereby make between armature 43 and elastic foot sheet 44 expansion.Then, rise and clamp-on the epimere face 22 of triangle 20 with stitch 45 arrival, armature 43 is adsorbed by the adsorption plane 10s of needle selecting actuator 10.Now, 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, the absorption of the slide cam selector 4 based on adsorption plane 10s is also difficult to be subject to the impact of this variation.Now, be preferably, slide cam selector 4 leaves from line 4w, 5w completely, and slide cam selector 4 is not in relying on the state of needle-bar 100.In addition, although rising use stitch 45 and epimere face 22 are isolated a little but still are isolated.
At this, even if make the state of slide cam selector 4 in not supported by needle-bar 100, produce the vibration of balladeur train 300 because being accompanied by the walking of 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 depart from from adsorption plane 10s.On the other hand, in the present embodiment, the abutting part 44b with clamp-oning triangle 20 butts in elastic foot sheet 44 becomes the fulcrum of spring to armature 43 application of forces towards needle tray 101, and this fulcrum of spring (abutting part 44b) in the bearing of trend of needle tray 101 on the formation scope that is adsorbed end face 43s of armature 43 position of repeating, therefore, be difficult to produce the moment centered by fulcrum of spring 44b.Therefore, do not use the electromagnetic force of needle selecting actuator 10 to make armature 43 depart from this situation and need to make the power effect of certain degree from adsorption plane 10s, under the extent of vibration of the balladeur train 300 producing being accompanied by the walking of balladeur train 300, armature 43 can depart from from adsorption plane 10s hardly.
As mentioned above, if armature 43 keeps being adsorbed the state of face 10s absorption and do not depart from, under the state floating at the epimere face 22 of certainly clamp-oning triangle 20 with stitch 45 that rises, move at the guide path B shown in Fig. 3 (D), do not clamp-oned the effect of triangle 20.Consequently, slide cam selector 4 does not move and maintains B position on the bearing of trend of needle tray 101.In this case, the braid movement of knitting needle 200 becomes flotation line braiding.
On the other hand, if armature 43 is departed from first disengaging region 12a of the needle selecting actuator 10 shown in Fig. 3 (D), rising is moved at guide path A with stitch 45.Particularly, as shown in Figure 5 (B), the stitch 45 for rising being departed from disengaging region 12a, 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, as shown in Fig. 3 (D), rising is extruded along the guide g1 being formed by the step between epimere face 22 and stage casing face 23 to tooth mouth side with stitch 45 and falls hypomere face 24.Fall the rising stitch 45 of hypomere face 24 and then be extruded to tooth mouth side along the guide g2 being formed by the step between stage casing face 23 and hypomere face 24, consequently, slide cam selector 4 arrives A position as shown in Figure 6.At this, owing to being formed with the 20b of wall portion between hypomere face 24 and stage casing face 23, therefore, can not climb on guide path H because the vibration of balladeur train 300 etc. causes rising to cross guide g2 with stitch 45.
Then,, as shown in Fig. 3 (D), if armature 43 is departed from by first disengaging region 12a of needle selecting actuator 10 and at second disengaging region 12b, rising is moved at guide path H with stitch 45.Particularly, rising is fallen the stage casing face 23 on the paper right side of clamp-oning triangle 20 with stitch 45, and is extruded to tooth mouth side along the guide g3 being formed by the step between epimere face 22 and stage casing face 23.Consequently, slide cam selector 4 arrives H position.At this, according to being arranged at the 20b of wall portion that clamp-ons triangle 20, rising can excessively not moved and climb on guide path A to tooth mouth side with stitch 45.
In addition, the present invention is not limited to above-mentioned embodiment, in the scope that does not depart from purport of the present invention, can suitably change.For example, also can be configured to, needle selecting actuator 10 faces slide cam selector 4 and slide cam selector 4 is sunk in needle tray 101 and be 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 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 be configured to the triangle of clamp-oning that makes its effect without this needle selecting cam.In this case, need to prepare separately needle selecting cam.
