Embodiment
Fig. 1 (a) is the structure that represents the major part of compound needle 11.Pin main body 12 and pusher jack 13 at compound needle 11 arrange respectively the heel 22 of pin driving needle and pusher jack driving needle heel 23.But, on the needle jack 24 that pin driving needle heel 22 is arranged on the afterbody of pin main body 12 is combined.Whether the heel 22 of pin driving needle and pusher jack driving needle heel 23 are arranged on the rear side of compound needle 11, give prominence to by the effect control of having omitted illustrated needle selection parts from needle tray surface.
Fig. 1 (b) is the structure that represents the major part that is mounted on the cam system 30 on the cam carrier using as the horizontal volume machine 21 of one embodiment of the invention.Cam system 30 is configured on the substrate 31 of the cam carrier that faces needle- bar 3,4, comprises rise cam 32, middle triangle 33, sitch cam 34,35 and pusher jack triangle 36 etc.Cam system 30 is configured to respect to center line 30c line symmetry, with respect to cam carrier traveling to the left and right, can make the effect of the heel 22 of pin driving needle and pusher jack driving needle heel 23 carry out comparably.But sitch cam 34,35 is correspondingly to pass through along the slip on the guiding road tilting with the direction of travel of cam carrier, the mode of change of location is controlled.Formerly lateral guide faller gill triangle 36 sides of sitch cam 34,35 are kept out of the way.The big or small density value of the coil forming as new coil in rear side and expression of sitch cam 34,35 is correspondingly to rise cam 32 side shiftings.
For example, in the case of the direction of travel of the cam carrier that moves to the left of figure for cam system 30, pin driving needle heel 22 is to be formed on pin path of navigation 37 between rise cam 32, middle triangle 33 and sitch cam 34,35 directed along track 22t.Pusher jack driving needle heel 23 is to be arranged on pusher jack path of navigation 38 on pusher jack triangle 36 directed along track 23t.
In the present embodiment, at pusher jack triangle 36, movable cam mechanism 40 is set.Movable cam mechanism 40 is included near suitable interval phase place in the pusher jack path of navigation 38 of pusher jack triangle 36 and center line 7c yarn feeder 7, the triangle parts 41 that carry out the effect that a part of track 23t is switched.Triangle parts 41 at one end have control part 41a, with according to swinging the effect to pusher jack driving needle heel 23 of displacement switch control portion 41a and not acting on, change the position of pusher jack driving needle heel 23, and the mode of the poor d of position generation of pusher jack 13 is controlled.The swing displacement of triangle parts 41 pushes and produces with respect to the drive division 41b of the other end because of push part 42.
Fig. 2 is the action of the movable cam mechanism 40 of presentation graphs 1.In triangle parts 41, control part 41a is switched at (a) and does not act on respect to the pusher jack driving needle heel 23 of passing through at track 23t, acts at (b).Triangle parts 41 are shaft-like, at the other end, drive division 41b are set.At pusher jack triangle 36, in the surperficial the inside side with respect to facing needle- bar 3,4, arrange accommodate triangle parts 41 accommodate recess 36a.Accommodating in recess 36a of pusher jack triangle 36, erect and arrange and can swing the flange 36b of support triangle parts 41 with displacement at the middle spaced winding axis of support 41c of control part 41a and drive division 41b.Push part 42 and torsion spring 43 act on triangle parts 41.In addition, in Fig. 2, for convenient, be illustrated in triangle parts 41 with solid line and be housed in and accommodate the part of recess 36a and accommodate the torsion spring 43 in recess 36a.They are present in the inside of pusher jack triangle 36, and in other figure, corresponding part represents with chain-dotted line.
Torsion spring 43, as shown in (a), does not suppress the direction of pusher jack driving needle heel 23 effects to control part 41a.Push part 42 possesses the pushing inclined plane 42a haunting.The front end of the nearby side that becomes figure of pushing inclined plane 42a tilts downwards, under the state that submerges shown in (a), with near drive division 41b butt front end of triangle parts 41.Push inclined plane 42a if make outstanding to the face side of paper,, as (b) as shown in, drive division 41b crosses pushing inclined plane 42a to the abutment portion of push part 42, to become push part 42 above pushing tabular surface 42b transfer.The transfer of this abutment portion is to make triangle parts 41 resist suppressing of being undertaken by torsion spring 43, swings in the clockwise direction displacement, and control part 41a acts on pusher jack driving needle heel 23.
Not by the swing displacement of such control part 41a, and by by the such slip of sitch cam 34,35, by push part 42 such the haunt effect of carrying out and the switching not acting on, also can control the position of pusher jack driving needle heel 23.In addition, based on swing displacement, slip in the situation that, also can make any one effect, by the difference of its position, control the position of pusher jack driving needle heel 23.Have again, even if acting on the triangle of pusher jack driving needle heel 23 fixes, if control to the mode of the side-prominent height of triangle from needle tray 5 to switch pusher jack driving needle heel 23, can, by triangle to acting on and not acting on and switching, the position of pusher jack driving needle heel 23 be controlled.In addition, if highly different agency parts is set at triangle, can be with the difference of the projecting height of pusher jack driving needle heel 23, to different Route guidings.
