Abstract
A knitting needle (10) for knitting machines has only one foot (15) which is arranged at one end of the knitting needle (10) and can be moved against spring force from a lower position into at least one raised position or from the raised position into at least one lowered position.
Description
Technical field
The present invention relates to a kind of knitting needle for knitting machine, this knitting needle has shank and at least one is arranged in the transmission foot on shank top, and shank is provided with pinhock, and transmission foot is for mobile knitting needle.
Background technology
In modern knitting machine, must just can complete three kinds of functions by knitting needle: lopping, pad are put tucked loop and suspended and be not touched position.These functions by knitting needle and the knitting system sliding along needle-bar coordinate realize, utilize described knitting system to carry out needle selection, the desirable function that will carry out of described knitting system drives knitting needle.Here, one or more transmission foots of knitting needle engage from different triangles by knitting system.
A kind of scheme that can guarantee three kinds of difference in functionalitys of knitting needle is to use so-called depressing cam.Driving member knitting needle or that be connected with knitting needle, project upwards the transmission foot in needle-bar, at transmission foot, through during triangle, at select location, be pressed in needle-bar, and then the engaging of disengaging and triangle.By cancelling pressure, corresponding transmission foot stretches out from needle-bar again, and can again engage with triangle.Here also transmission foot only partly can be pushed back in needle-bar, this transmission foot can be clamped by other triangular portions, and can realize other function of knitting needle.Use baroque depressing cam, except knitting needle, also need to use the driving member that is provided with equally transmission foot.And there is following risk, and knitting needle can inadvertently sink in needle-bar when knitting needle longitudinal loading is very large, and this can cause function error.
Except using depressing cam, known use rise cam also.Here, the transmission foot of knitting needle or relevant driving member is deposited in needle-bar at the beginning, and enhances from needle-bar at the given position of three corner channels.In this way can be so that transmission foot engages from different triangles.Through after triangle, on one's own initiative transmission foot is pushed back in needle-bar, to be disengaged.This rise cam is for example recorded to some extent in EP 0 189 602 B1.Use the shortcoming of rise cam to be, pin heel must push back in needle-bar on one's own initiative through after triangle, and this causes that the distance between each knitting system increases.In addition, through during triangle, must from below, support in some position pin heel, to prevent, inadvertently be deposited in needle-bar.In conjunction with rise cam, the following knitting needle of known use also, the transmission foot of this knitting needle utilizes elastic force to be deposited in needle-bar.But must on this knitting needle, be provided with the second transmission foot, the second transmission foot draws knitting needle to be back to neat and well spaced alignment.This known knitting needle is therefore long, and this requires again needle-bar to have corresponding physical dimension on knitting needle is longitudinal.
By the known another kind of triangle of CN 101314887 A, wherein can touch knitting needle or relevant driving member in different positions.Except knitting needle, this triangle also forces to need driving member.The position of this driving member in being suppressed is also fixing.In the precalculated position of three corner channels, can cancel fixing these parts.So the stress of these parts makes transmission foot engage with triangle.The residual stress staying prevents that transmission foot from departing from through during triangle.But this residual elasticity power can only be very little, because also must overcome this residual elasticity power when needing to retighten driving member after triangle.
Finally, by the known a kind of knitting needle of EP 1 569 065 A1, it only has a transmission foot, but whole shank is all flexible parts.Yet adopt this design can make knitting needle be distorted under lateral load, but also can make the transmission foot of this knitting needle inadvertently be deposited in needle-bar.
Summary of the invention
The object of the invention is to, a kind of knitting needle for knitting machine is provided, and it is simple in structure, and can in needle-bar, by knitting system, be actuated without extra driving member, for carrying out selectively one of three kinds of functions, i.e. lopping, pad are put tuck or time-out and are not touched.
This object realizes by a kind of knitting needle for knitting machine, this knitting needle has shank and at least one is arranged in the transmission foot on shank top, shank is provided with pinhock, transmission foot for mobile knitting needle, is characterized in that, is only provided with a transmission foot, this transmission foot is arranged on one end relative with pinhock of knitting needle, and can overcome elastic force, from position below, move to the position that at least one is mentioned, or from the position of mentioning, move to the position of at least one decline.
The shank of this knitting needle is at least mainly made by compliant material, thereby has needed intensity.Owing to being only provided with a transmission foot, therefore knitting needle structure is simple, and Length Ratio is shorter.Because be utilize knitting needle originally with it the elastic force of generation realize and make transmission foot on one of end position, therefore only need actuate on one's own initiative transmission foot in a direction of motion.Therefore, knitting needle only need seldom need to be arranged among needle-bar or on driving member.This can make the structure of needle-bar narrow knitting needle is longitudinal.For actuating the triangle of knitting needle, also can there is fairly simple structure.Only need apply power to a transmission foot.One of the direction of motion that also can utilize elastic force to realize to make transmission foot is longitudinal transverse to knitting needle, so this point is without realizing on one's own initiative.Without using depressing cam or rise cam.
According to a kind of preferred design, transmission foot can not project upwards in shank or needle-bar in the position of its outmost decline.In this position, knitting needle thereby do not clamped by triangular portions.On the other hand, transmission foot at least can project upwards in shank or needle-bar in its outmost position of mentioning, thereby this transmission foot can be clamped by triangular portions.Can also make transmission foot be in the ，Gai centre position, centre position between its outmost position of mentioning and the position of its outmost decline, transmission foot projects upwards equally in shank.
Can carry out different designs to knitting needle structure.According to the first Variant Design, transmission foot can be arranged in the elastic segments of shank.Knitting needle thereby be structure as a whole.Because shank can be for bending resistance designs outside Hookean region, therefore guaranteed needed knitting needle mechanical strength.
According to another kind design, transmission foot can be placed on the swing component hinged with shank, and wherein swing component can overcome in one direction elastic force and swings with respect to shank.The knitting needle of this two component Design can also be realized and regulate as required transmission foot.Here, elastic force can be produced by elastic segments shank or swing component.
Further advantageously, shank has backstop, and described backstop at least limiting the motion of transmission foot in one of direction of motion of transmission foot.This backstop is responsible for making the end position that transmission foot can be in regulation, and for the knitting needle with shank elastic segments, simultaneously for stablizing elastic segments.
