Description

Knitting machine
Technical field
The present invention relates to a kind of knitting machine, have at least one needle-bar, in its needle track, can support particularly knitting needle of insert with vertically moving, wherein, insert has lock face, and this lock face is not being chosen under the situation of insert from needle-bar end face convexity.
Background technology
Through promoting the transmission heel of insert, the pin heel can seesaw in needle track with trigonometric curve (Schlosskurve) interlocking of knitting system and corresponding with the distribution of trigonometric curve.Promote from needle-bar on which time point according to transmission heel, it can be caught by different trigonometric curves, thus can with realize so-called frequency multiplexing technique.If insert is a knitting needle, knitting needle forms coil or tuck in the book according to the trigonometric curve of catching the transmission heel so.If not lift pins heel, it remains on unactivated sinking in the position so.Sink to needle-bar for transmission is called in person, thereby insert does not move through knitting system, for example known so-called pressure triangle.Utilize this triangle on the time point of confirming, thereby the transmission heel of knitting needle to be pressed into the chimeric of needle-bar and disengaging and triangle.For promoting triangle, then promote the transmission heel of knitting needle or other inserts on the contrary through triangle or other inserts.After triangle is through (Schlossdurchgang), transmission heel or activation, or through in the spring force pressure back stitching bed.
Because the pressure trigonometric sum promotes relative complex on the three-legged structure, so also proposed to have the triangle of different activationary time points, the optional feature that wherein will be connected with the knitting needle form fit is sent in the position of tensioned and is also fixed.Cancellation is this on the time point of confirming that triangle passes through fixes, and the triangle interlocking is carried out in the transmission of knitting needle heel thus.Known in addition knitting needle with spring lever, the transmission heel is arranged on its end, and wherein, the spring force of shank remains on the transmission heel on the position of sinking to needle-bar.But these knitting needles are very unstable, thereby knitting needle can buckling under the situation that the transmission heel loads through trigonometric curve.
In all solutions; Except the reliable lifting and decline of insert; The important insert that also has is not rabbeted under the situation that just they are in its un-activation position or the transmission heel promotes with trigonometric curve in its transmission heel; Do not implement needle track and vertically go up undesirable motion, particularly pulling motion.
Summary of the invention
The objective of the invention is to, a kind of knitting machine is provided, wherein drop under the situation in the needle-bar in the transmission of insert heel, reliably stop or can limit at least insert its vertically on motion.
This purpose is achieved through a kind of knitting machine with at least one needle-bar; In its needle track, can support particularly knitting needle of insert with vertically moving; Wherein, insert has under the situation that insert is not chosen does not call in person from the protruding transmission of needle-bar end face, it is characterized in that; On insert, constitute at least one abutment face, this abutment face sinks in the transmission heel of insert and abuts at least one substantial lateral under the situation in the needle-bar on the lock face of the portrait orientation of insert.
The knitting machine that constitutes according to the present invention limits the vertically moving property of not choosing or be in the insert in the process of choosing at least, or also gets rid of this vertically moving property fully.If insert is a knitting needle, can avoid these knitting needles undesirably to be drawn forward so thus, although said knitting needle is not chosen through the power that yarn acts on the knitting needle direction of motion.Therefore can avoid conflicting with the knitting needle on opposite and avoiding the coil that is on the pinhock is had a negative impact.
If knitting machine constitutes in addition like this, abutment face is only just no longer abutted on the lock face under the situation that the transmission heel promotes from needle-bar fully, so also can get rid of insert vertically moving during choosing process.This point is particularly significant in this case, i.e. the lifting of transmission heel is carried out through second insert, this second insert first insert vertically on be pulled to below its transmission heel.Forward travel through choosing insert the insert that will choose vertically on act on the insert that this institute will choose force component can be compensated thus.In this regard, one of these abutment faces of insert or abutment face need not to abut in all the time on unique lock face during choosing process, but also can for example at first abut on first lock face and and then abut on second lock face.
Interior step constituted at the bottom of one of these lock faces or lock face for example can be used as the pin of needle-bar.Under the situation that the transmission heel is sunk,, continued to promote by corresponding amplitude ground until the transmission heel so at least one abutment face of insert abuts on this step.
Said at least one lock face for example also can be formed by the silk thread that vertically distributes transverse to insert certainly.Silk thread or the lath of laterally leading whole needle-bar provide the possibility of for each needle track, making lock face simple in structure and inexpensively.
Lock face can certainly at least partly be arranged on the triangle (Schlossteil).In this case, the abutment face of insert preferably is in the transmission heel of insert.
When having the silk thread that is used to form lock face, the abutment face of insert preferably has the distribution that in the cross section, takes the shape of the letter U like this, thereby silk thread can insert between the arm of abutment face.In this manner, can realize that insert is along the locking on two moving directions of needle track.As additional or selection, the abutment face of formation transverse to the plane of insert portrait orientation can be set.
Abutment face can be arranged on the optional position of insert in this regard in principle, but is preferably disposed in the zone of transmission heel.This point particularly is fit to the transmission heel and is arranged on the situation on the insert rear end.If heel is sunk in the needle-bar, so abutment face also sink to needle-bar and can with the set lock face acting in conjunction in there.
Lock face and/or abutment face preferably can be processed or had the coating that reduces wearing and tearing or through Overheating Treatment by high-abrasive material.Except having corresponding coating, can consider that also these faces are through independent parts armouring.Design through on abutment face and the lock face geometric modeling also can reduce wear.These faces for example can and/or itself arch upward through the rounded edge restriction.
In a kind of preferred formation of knitting machine, the transmission heel can promote against the spring force that acts on it.This means that the transmission heel is returned in its original position that sinks to needle-bar automatically when choosing of insert finished.On needle track is vertical, observe thus and can produce narrow needle-bar, because only need be provided for promoting the driving member that the transmission heel for example promotes the pusher jack form.Triangle can relatively simply constitute in this case.Can cancel pressure triangulation techniques
Figure BSA00000669156000031
What can realize similar advantage is that insert can turn round and be arranged on the gyration lifting that needle track is interior and transmission is called in person and can be passed through insert.Here insert also can constitute like this, and just occupying it automatically sinks to the original position in the needle-bar thereby the transmission heel is not as long as insert is through choosing the part loading.
For realizing simple especially three-legged structure, what have advantage in addition is that insert has only transmission heel.Also only must have and the pin corresponding trigonometric curve of calling in person so call in person for this transmission in the knitting system.
Knitting needle both can also can constitute on many parts ground integratedly.
