The needle selection sinker

Technical field

The present invention relates to a kind of needle selection sinker (Auswahlplatine) that is used for being arranged in the knitting mechanism of knitting machine needle-bar needle tray, this sinker is arranged in the needle tray of knitting mechanism with longitudinal movement, and can be applied power by the magnet of knitting machine needle selecting system by escapement face (Ankerfl che).

Background technology

This needle selection sinker is for example known by EP 1 275 762 A1.This known sinker is arranged in the needle tray swingably, and is unclamped by the magnet of needle selecting system under the needle selection situation, and utilizes elastic force to be rocked to the needle selection position.Next, this sinker is pushed ahead in needle tray by triangle by vertical transmission pin.When the needle selection sinker is pushed ahead, make an additional needle-bar insert engage.

This needle selection sinker is owing to the transmission pin vertically has long length.In addition in knitting system, must move with rollback at pushing ahead of needle selection sinker each triangle is set, improved the triangle manufacturing cost thus.

Summary of the invention

The objective of the invention is to, provide a kind of length short, simple in structure needle selection sinker, it can also simplify the structure of triangle.

According to the present invention, described purpose realizes with following measure by the needle selection sinker of the described type of the beginning part, promptly this needle selection sinker have the knitting needle substrate that is substantially perpendicular to needle tray before push away face (Vortriebsfl che), push away face before being somebody's turn to do and do not protrude in the escapement face, by pushing away face before this, can apply power to this needle selection sinker by driving member, so that in needle tray, push ahead.

In order to realize pushing ahead, needle selection sinker of the present invention need not the upwards transmission pin of projection.The pushing ahead thereby needn't be undertaken of needle selection sinker by triangle.Or rather, sinker moves forward in needle tray under the needle selection situation by pushing away the driving member on the face before acting on, so that for example make knitting needle directly or by middleware, can engage with the triangle of knitting system.

According to a kind of preferred design, precedingly push away the terminal surface that face can form the back of needle selection sinker.So can apply power to this needle selection sinker by the driving member of effect on needle tray is vertical, push ahead so that realize.

Further advantageously, precedingly push away face and the escapement face is adjacent to be arranged on the end section of needle selection sinker.Take this measure can further shorten the length of needle selection sinker.

Here, end section can limitedly swingingly be arranged on the needle selection sinker at least.End section thus can be under non-needle selection situation towards the magnet swing of needle selecting system, and at the next magnet that is swung away from of needle selection situation.

In order to guarantee that under the needle selection situation escapement face breaks away from reliably in magnet, in addition advantageously, is arranged in end section on the elastic segments of needle selection sinker.Under non-needle selection situation, end section overcomes elastic force by attraction.Under the needle selection situation, elastic segments makes end section move away magnet, thereby can apply power to preceding pushing away face by driving member.

But end section also can be arranged in vertical contact pin of rigidity of needle selection sinker, and the needle selection sinker can be arranged in the needle tray, and can overcome the power of elastic component and swing.According to this design, this magnet is swung and be swung away to the needle selection sinker that is the bending resistance structure except elastic component towards the magnet of needle selecting system as a whole.In case the magnet of needle selecting system has unclamped sinker, just realize moving to the needle selection position by elastic component equally here.Elastic component and needle selection sinker are preferably constructed integratedly, and this has simplified the structure of needle selection sinker, and then has reduced manufacturing cost.

The needle selection sinker can have the backstop of the oscillating motion that is used for the confinement end section, can realize other advantage thus.The end position of needle selection sinker is accurately limited thus.

In addition advantageously, the needle selection sinker has the preceding contact-making surface that is used for the power that applies to knitting mechanism or middleware.If the needle selection sinker is pushed ahead, then it can will before push moving being delivered on the knitting mechanism by means of its contact-making surface.

Needle selection sinker rollback moves to its original position or is undertaken by knitting mechanism, if utilize triangle to make this knitting mechanism in needle tray, move backward, undertaken by at least one actuating pin that protrudes in needle-bar, this actuating pin is used to cause rectilinear motion backward.

According to another preferred embodiment, if this needle selection sinker is maintained by the magnet of needle selecting system by its escapement face, then can be with the axial location locking of needle selection sinker in needle tray.After being unclamped by magnet, the needle selection sinker has the axial location of regulation in the Background Region of needle tray, thereby this needle selection sinker can apply power reliably by pushing away the face transmission part before it.

In order to realize this axial restraint, this needle selection sinker can have breach, and the lock piece that is arranged in the needle-bar can be embedded in this breach, if the needle selection sinker is with the magnet swing of its escapement face towards needle selecting system.When the latch design part, can consider to adopt various scheme.A kind of dog-cheap solution is, lock piece is a kind of wire rod, and this wire rod runs transverse through needle tray along needle-bar in the zone of needle selection magnet.So, only a unique lock piece need be set at whole needle selection sinkers of needle-bar.

Still decide the below top that is arranged on needle-bar on needle selecting system, and the needle selection sinker that is inserted in the needle tray can be towards the needle-bar end face, perhaps towards the needle-bar bottom surface, so that this needle selection sinker can be maintained by the magnet of needle selecting system.
