The cam system of footwear machine
Technical field
The present invention relates to a kind of cam systems of footwear machine.
Background technique
The cam system of footwear machine is set to the position for being located at main mouth on the tablet of footwear machine, and effect is to pass through guiding
It the braiding step such as reaches the socks needle upstream or downstream of the main mouth position of footwear machine to complete band yarn, lopping, move back circle, while guiding socks needle
Run by different route, to determine whether socks needle participates in weaving, the cam system of footwear machine include left water chestnut 1, left panelling 2,
The components such as middle water chestnut 3, right water chestnut 4, right panelling 5 are simultaneously circumferentially set as symmetric triangular seat (as shown in Fig. 1) along syringe.
Loop selection is a kind of braid mean for increasing socks grain pattern color change, it is common practice in the main mouth of footwear machine
Carry out the setting of position forwards jacquard weaving openings relative to syringe, knitting needle has pattern thread in jacquard weaving openings and (moves back circle, band yarn, band yarn to walk
Suddenly main mouth is then moved to), and lopping step is completed by cam system.Since the braiding of heel and undertoe is by the syringe inverse time
Needle turns half-turn and then turns half-turn clockwise and move in circles to complete braiding, if making loop selection in heel and toes
Socks needle is just needed first to eat pattern thread (completing to move back circle, band yarn, band yarn step) before reaching the main mouth of footwear machine, thus just must be
The main mouth two sides of footwear machine repeat setting jacquard weaving openings, can not only tie up the originally narrow locational space of hosiery machine in this way, while but also
The programming of the automatic control program of footwear machine becomes increasingly complex thus traditional footwear machine in order to avoid in the main mouth two of footwear machine
Stress multiple setting jacquard weaving openings, the braiding function that footwear machine does jacquard weave in braiding socks root and toes can only have been given up.In order to more
The missing of such a braiding function of traditional footwear machine is mended, existing solution is:
When the main mouth of footwear machine is rotated clockwise relative to syringe syringe come to front on the downside of it is same with positive slide cam selector 8
The position of height is arranged reversed slide cam selector 9(and sees attached drawing 1), when carrying out the loop selection of heel or undertoe, leading above main mouth
Yarn device sets jacquard weave shuttle and works alternatively with heel and undertoe braiding shuttle, and the half cycle on syringe where sole needle 6 is in participation
The operating position of heel and undertoe braiding.When syringe revolves biography (see attached drawing 2) counterclockwise, sole needle 6 by positive 8 needle selection of slide cam selector,
Cable guiding device jacquard weave shuttle is laid, and the sole needle 6 chosen moves back circle side 45 by the right side of right water chestnut 4 and is lifted to right top margin 41(upwards and moves back
Circle), along right band yarn side 31 downward (band yarn) to middle water chestnut bottom point 32 after water chestnut 3 along the horizontal operating arrival of right top margin 41, then
Level operating eats pattern thread (band yarn) and comes downwards to left bottom edge 13(lopping along left lopping side 12 when reaching left water chestnut 1), through left bottom
While 13 again along left card stripping while 21 go upward to behind left 21 vertex of card stripping side horizontal operating and compiled to the half-turn that syringe rotates counterclockwise is completed
It knits;The sole needle 6 not being selected comes downwards to right bottom edge 43, level operating to the left bottom edge of left water chestnut 1 along right second side 44
The 13 continuation level operatings behind 21 vertex when 21 go upward to left card stripping along left card stripping again, trail last piece short bell needle 6 and enter master
The length of mouth is called in person, and needle 7 is identical as the running route of unchecked sole needle 6 to be not involved in braiding;(see attached drawing when syringe rotates clockwise
3) 9 needle selection of slide cam selector, is not reversed by the sole needle 6 of positive 8 needle selection of slide cam selector before, cable guiding device jacquard weave shuttle lifts, socks
With or undertoe braiding shuttle lay, be reversed sole needle 6 that slide cam selector 9 is chosen by a left side for left water chestnut 1 and move back the effect of circle side 15
It is lifted to left top margin 11(upwards and moves back circle), it (is padded downwards after water chestnut 3 along left band yarn side 33 along the horizontal operating arrival of left top margin 11
Yarn), heel or undertoe line (band yarn) are eaten when then horizontal operating reaches right water chestnut 4 and come downwards to right bottom edge along right lopping side 42
43(lopping), through right bottom edge 43, along right card stripping, when 51 go upward to right card stripping, syringe up time is extremely completed in horizontal operating behind 51 vertex again
The half-turn braiding of needle rotation;It is not reversed the sole needle 6 that slide cam selector 9 is chosen and comes downwards to left bottom edge 13, water along left second side 14
To the right bottom edge 43 of right water chestnut 4, along right card stripping, when 51 go upward to right card stripping, continuation level is operated behind 51 vertex again for flat operating, needle
Trailing sole needle 6 enters the long heel needle 7 of main mouth and is not reversed the operation of sole needle 6 that slide cam selector 9 is chosen when cylinder rotates counterclockwise
Route is identical to be not involved in braiding.Syringe moves in circles rotation with regard to achievable heel or the loop selection of undertoe.
In above-mentioned solution, jacquard weave shuttle is set by the way that reversed slide cam selector 9 and the main mouth yarn guide of footwear machine is arranged, is made
In the main mouth of footwear machine all braiding steps such as the band yarn of pattern thread, band yarn, lopping can be completed, moves back circle in socks needle, without logical
Pattern thread (band yarn, band yarn step) is eaten in the jacquard weaving openings completion crossed outside main mouth, thus simply and easily compensates for traditional footwear machine
It is difficult to make the afunction of loop selection in heel and undertoe, but above-mentioned solution still remains such problems:
1. lopping step is completed when syringe rotates counterclockwise during the loop selection of above-mentioned heel and undertoe
Sole needle 6 (is not reversed slide cam selector 9 to choose) at this time when syringe rotates clockwise must be from the horizontal fortune in the left bottom edge of left water chestnut 1 13
Go to the right bottom edge 43 of right water chestnut 4, in the process due to sole needle 6 be in lower position and level run distance it is longer so that
Pattern thread stress is larger to be also easy to produce fatigue and breaks;Equally, the short of lopping step is completed when syringe rotates clockwise
Heel needle 6 (is not chosen) when syringe rotates counterclockwise by positive slide cam selector 8 at this time must be from the horizontal operating in the right bottom edge of right water chestnut 4 43
To the left bottom edge 43 of left water chestnut 1, in the process since sole needle 6 is in lower position and level run distance is longer so that socks
With or undertoe line stress it is larger be also easy to produce fatigue and break.
2. selected sole needle 6 moves back circle side 15 along a left side for left water chestnut 1 and goes upward to left top margin when syringe rotates counterclockwise
11, and lopping but not yet is completed when syringe rotates clockwise along left second side 14(for adjacent not selected sole needle 6
Move back circle) come downwards to pull during left 13 position of bottom edge yarn to 6 needle back of sole needle for moving back circle 15 uplink of side along a left side generate compared with
Big active force, and maximum is reached to the pulling force of yarn when reaching left 13 position of bottom edge, cause the sole needle 6 of uplink because of stress
Deformation and needle latch position shifts, in turn result in that sole needle 6 cannot eat line or needle latch is interrupted;Equally, clockwise in syringe
When rotation, come downwards to right bottom edge 43 sole needle 6 pull yarn to along the right side move back circle 45 uplink of side sole needle 6 needle back generate compared with
Big active force, causing the sole needle 6 of uplink, needle latch position shifts due to stress deformation, and in turn resulting in sole needle 6 cannot
It eats line or needle latch is interrupted.
The presence of above-mentioned two problems certainly will influence whether the weaving quality of socks, ask to further solve above-mentioned technology

42 i.e. level runs when running down to the height and position of right 4402 minimum point of second side back segment, and this duration heel needle 7 is right
The pulling force of yarn is smaller, thus yarn will not call in person to along the long of right 4500 uplink of third side (circle, band yarn step are moved back in completion)
The needle back of needle 7 generates biggish active force, would not also occur in this way socks needle because caused by stress deformation needle latch be subjected to displacement without
Line can be eaten or the phenomenon that needle latch is interrupted;
Likewise, since left lopping cam 11 goes out position, the long Heels needle 7 not being selected exists when syringe is rotated clockwise
The height and position level run of left 1402 minimum point of second side back segment is to right lopping cam 42, thus long Heels needle 7 is moved back from a left side
It is smaller to the pulling force of yarn during the circle operation to right lopping cam 41 of cam 12, it is not in that yarn breaks because of stress fatigue
Line;Simultaneously as long Heels needle 7(is completed lopping but does not move back circle) along a left side move back circle cam 12 run down to left second side back segment
Level run when the height and position of 1402 minimum points, and this duration heel needle 7 is smaller to the pulling force of yarn, thus yarn will not
Biggish active force is generated to the needle back of the long heel needle 7 along left 1500 uplink of third side (circle, band yarn step are moved back in completion), in this way
Also socks needle would not occur cannot eat line or the phenomenon that needle latch is interrupted because needle latch is caused to be subjected to displacement for stress deformation.
Thus, the present invention ensures the weaving quality of socks while realizing heel or undertoe loop selection.
