Description
Technical field
The present invention relates to a kind of pusher jack of knitting needle of knitting machine, wherein knitting needle is arranged in a needle tray of needle-bar, and can make a transmission foot sinking in needle-bar of knitting needle be raised on needle-bar with this pusher jack.
Background technology
For knitting machine, especially such pusher jack of the knitting needle of flat machine is well-known.For example document DE687 608 has illustrated a kind of selection pusher jack, can make a transmission foot sinking in needle-bar of knitting needle be raised on needle-bar, to can clamp transmission foot by the triangle of knitting system with this pusher jack.Transmission foot has been determined by the distance of Triangulum process: what function knitting needle implements, and in other words, whether it forms coil, tuck in the book whether, or remain on a torpescence position.
Known selection pusher jack complex structure.In addition all can not stop the transmission foot of knitting needle to avale unintentionally before, if knitting needle stand under load strongly in the axial direction.
Summary of the invention
Task of the present invention is: propose a kind of pusher jack, it both can make the transmission foot of knitting needle lift reliably, also can stop transmission foot to sink in needle-bar unintentionally.
Task solves by a kind of pusher jack of the knitting needle in knitting machine, wherein knitting needle is arranged in a needle tray of needle-bar, and can make a transmission foot sinking in needle-bar of knitting needle be raised on needle-bar with this pusher jack, it is characterized in that, can form the pin of a knitting needle with this pusher jack at the bottom of, with stoping the transmission foot of knitting needle to sink in needle-bar at the bottom of this pin.
Therefore, at the bottom of can forming a pin according to pusher jack of the present invention, when knitting needle is especially in its return motion at the bottom of this pin, can in needle tray, slides, and when the axial stand under load of knitting needle, stop sinking to of pin heel.Pusher jack is simultaneously for guaranteeing that the transmission foot of knitting needle reliably lifts, thereby the needle cam by knitting system detects knitting needle and can meet a kind of desirable function, as formed coil, tuck in the book, remain on idle position, coil shifts or coil is accepted.Knitting needle preferentially only has a unique transmission foot.
If transmission foot can overcome a spring force acting on above it, by pusher jack, lift, that just has additional advantage.Transmission foot is returned to it and sinks on the position in needle-bar and needn't be undertaken by pusher jack or another element.But by spring force, reply on one's own initiative, this spring force preferentially can be produced by knitting needle itself.
For the design of pusher jack, can consider various possibility.
A kind of possibility is: pusher jack is arranged in needle tray, to move point-blank.Movement by pusher jack towards knitting needle, can lift transmission foot by means of a guide pin fragment, and at the bottom of forming pin.As long as pusher jack rests on it in advance on mobile position, at the bottom of it just forms pin, at the bottom of this pin, stoped undesigned the sinking to of transmission foot of knitting needle.Along with a kind of unique motion of pusher jack can realize two kinds of functions, at the bottom of lifting transmission foot and forming pin.If pusher jack by an angle can return motion to its inactive initial position, that is again favourable.This return motion can be implemented in the triangle stroke end of attached knitting needle.Therefore the transmission foot of knitting needle can sink in needle-bar again.
Yet pusher jack also can be arranged in needle tray swingably.If pusher jack, on its inactive initial position, is held knitting needle below also in transmission foot position, just do not needed rectilinear motion so here.Swing guide faller gill, just both can lift transmission foot so, and at the bottom of forming pin again, the latter stops transmission foot to sink to unintentionally.
In this design, pusher jack can be by transmission foot effect in other words power in the above, can return motion to its inactive initial position.Pusher jack must be driven on one's own initiative, just for lifting transmission foot.
Yet also can, pusher jack is designed to can swing in the direction in contrast to spring force.For pusher jack, also just on a swaying direction, need so the driving of an active.In this design, pusher jack return motion can be passed through spring force to its inactive initial position, namely carries out passively.
Pusher jack needn't be arranged in needle-bar.Also can make it be arranged in a pusher jack bed separating, wherein they can be arranged in this bed and can move or swing.
