Description
Technical field
The present invention relates to a kind of function element that is used for knitting machine, this function element has the driving needle heel (Antriebsfu β) at the place, end that is arranged in function element to be used for the motion of function element with respect to the needle-bar of knitting machine.
Background technology
In the knitting machine in modern times, must be able to realize three functions: form looped pile (Masche), insertion tuck flotation line (Fanghenkel) and time-out in the position of static (inaktive) by means of knitting needle (Stricknadel).Realize these functions by knitting needle and the acting in conjunction of crossing the knitting system that needle-bar slides, utilize knitting system to carry out that pin is selected and this knitting system corresponding to the function driving needle to be performed of expectation.At this, the heel of the driving needle of knitting needle arrives with in the joint of the different cam track in knitting system place (Schlosskurve).
A kind of possibility of three different functions of knitting needle that guarantees is present in use so-called depressing cam (Dr ü ckerschloss).During cam track was passed in pin heel, the driving needle heel that surpasses needle-bar that protrudes upward of pin or the driving element that is connected with pin was forced in the needle-bar at selected position, and is disengaged with triangle (Schloss) thus.By the elimination of pressure, corresponding driving pin heel is lifted from needle-bar once more, and can be once more with it with during the triangle introducing engages.At this, also possible is, only partly the driving needle heel is pushed back in the needle-bar, thereby can be caught the driving needle heel and can be realized other function of knitting needle by other triangle parts (Schlossteil).Therefore, driving needle heel can be positioned in the different working depths, the driving needle heel in different working depths with different triangle parts actings in conjunction.Except pin, use depressing cam complicated on the structure additionally to need to use the driving element that is provided with the driving needle heel equally.In addition, have such danger, that is, when existing than heavy load in a longitudinal direction, knitting needle can by mistake sink in the needle-bar, and this causes functional fault.
Except the use of depressing cam, the use of rise cam (Hebeschloss) also is known.At this, the heel of the driving needle of pin or relevant driving element is at first sunk in needle-bar, and promotes from needle-bar at the position of being scheduled to of triangle by (Schlossdurchgang).By this way, driving needle heel can be introduced in the joint with different cam tracks.After triangle passes through, on one's own initiative the driving needle heel is pushed back in the needle-bar, to be disengaged.For example, in file EP 0 189 602 B1, this rise cam has been described.Use the shortcoming of rise cam to be, triangle by after must on one's own initiative pin be called in person and push back in the needle-bar, this prerequisite is the bigger spacing between single knitting system.In addition, must be during triangle passes through at several positions from the heel of supported underneath pin, by mistake sink in the needle-bar preventing.In conjunction with rise cam, the use of such pin also is known, that is, therein, by elastic force the driving needle heel is sunk in the needle-bar.Yet, the heel of second driving needle must be set at the pin place, it leads back to knocking over level (Kammgleiche) with pin.Therefore, this known pin is long relatively, and this needs the corresponding structure size of needle-bar then on the pin longitudinal direction.
In addition, the shortcoming of the arrangement of file EP 0 189 602 A1 is, the driving needle heel is relevant therewith with respect to the angle of pin substrate (Nadelgrund), that is, how far (herausschauen) found out in the driving needle heel from needle-bar have.Thus, pin heel shape can be optimum for a working depth only.The optimization of other working depth is impossible or it causes higher wearing and tearing.
The known straight-bar machines (Flachstrickmaschine) that has the pin selecting arrangement from file DE 35 41 171 A1.At this, (Kupplungsteil) is combined for pin and connecting piece, wherein, is provided with the driving needle heel at the connecting piece place.At this, the pin connecting piece must far extend to after the pin heel, to guarantee that the pin heel keeps constant angles with respect to needle-bar.
File DE 27 35 492 A1 disclose a kind of electric motor type selective system that is used for circular knitting machine.Needle set has the driving needle heel.Rearward end place at pin is provided with recess, middle needle jack
Be bearing in swingably in this recess.Middle needle jack center, side place thereon has the driving needle heel, and has jut to be used for locking or to be clamped on the jacquard weave needle jack at its place, end that deviates from pin
Fork-shaped portion (Gabel) in off-position.Heel only is provided with an operating position for driving needle.
File DE 29 07 795 A1 disclose and have been used for the device that have looped pile formation element of individual operation in the work package of knitting machine.Mode with many makes up pin, and wherein, the lower part of pin is bearing in the anterior office of pin swingably.The lower part of pin has the driving needle heel, yet this driving needle heel is not to be arranged in place, the end of pin.In addition, heel is not provided with different working depths for driving needle.If following pin is partly swung, then the orientation (Orientierung) of driving needle heel changes.
Known a kind of knitting machine from file DD 241 621 A5, it has pin in the groove of needle-bar.Pin utilizes its forward part to be arranged in bottom land.If the driving needle heel changes on its height, then its directed change.Heel only is provided with a working depth for driving needle.

Purpose of the present invention is, is provided for the function element of knitting machine, and this function element makes up simple, can not have to drive this function element by knitting system under the situation of additional drive elements and this function element is implemented as short as far as possible in needle-bar.
This purpose realizes by the function element that is used for knitting machine, this function element has the driving needle heel at the place, end that is arranged in function element to be used for the motion of function element with respect to the needle-bar of knitting machine, wherein, the driving needle heel can be moved at least two working depths, and so be arranged in the function element place, that is, driving needle is arrived upon the heels of another to lack and have identical orientation all the time with respect to needle-bar on its working depth.Preferably, the driving needle heel has identical orientation (Ausrichtung) with respect to needle-bar on all height and positions.Function element can be pin, selection element or other element of knitting machine.Preferably, function element only has a driving needle heel.Thus, function element structurally is simple, and has relatively little physical dimension.Because the driving needle heel is arranged in the place, end of function element, so function element is embodied as very short.Can reduce the physical dimension of needle-bar thus.Preferably, the driving needle heel is arranged to and can sinks in needle-bar.In lax (entspannt) state, the driving needle heel can superposed position in, in the position of bottom or arbitrarily in the centre position or even be located in the position outside the working region to be used to obtain prestressing force.
Advantageously, the driving needle heel can allow the driving needle heel to be connected with the function element main body with respect to the Connection Element of function element main body motion by at least one.Feasible thus is that the driving needle heel occupies different working depths.At this, at least one Connection Element is embodied as flexible.If it is flexible that in the Connection Element one is implemented as, the certain height of then default (voreinstellen) driving needle heel.The effect that can overcome elastic force occupies another height, working depth especially.Yet what also can imagine is, the elastic component by the outside applies elastic force, and this elastic component pin heel does not have optimum position (Vorzugslage).In particular, because elastic force, can occupy in the final position of driving needle heel.Can produce elastic force by function element self.If be this situation, then only driving needle heel must be driven on one's own initiative transverse on one in the direction of motion of the longitudinal axis of function element.Therefore, only need seldom wait to be arranged in the needle-bar or the driving element that is used for function element at needle-bar place.This makes the relatively little physical dimension at pin longitudinal direction upper stitch bed become possibility.Equally, the knitting cam (Strickschloss) that is used to drive function element can have simple relatively structure.Only need to load a driving needle heel.In addition, bear transverse to one in the direction of motion of the driving needle of function element longitudinal direction heel, that is, needn't activate on one's own initiative by elastic force
This direction of motion.Needn't use depressing cam or rise cam.Preferably, so design Connection Element, that is, and the pulling force and the pressure that occur by knitting cam when Connection Element can be delivered in the heel of load driver pin.
Special advantage is that the driving needle heel is arranged in hingedly the swing element place that (gelenkig) is connected with the function element main body, or hingedly is connected with the function element main body.Swing element is considered as the part of function element.Because the driving needle heel is arranged in the place, end of function element, this means that also the driving needle heel is arranged in the place, end of swing element.At this, function element can be configured to single-piece or two-piece type.Swing element can overcome elastic force and swing with respect to the function element main body.At this, can produce elastic force by the flexible section of function element main body and/or the flexible section of swing element.Yet what also can establish elephant is to produce elastic force by additional flexible member.Can on both direction, activate the motion up and down of driving needle heel equally by additional needle-bar element and/or knitting cam.So, function element is embodied as stiff.
In design of the present invention, can be provided for the guide portion of driving needle heel.Can guarantee that by this guide portion it is constant that the angle between driving needle heel and needle-bar or the pin substrate keeps.The pulling force and the pressure that occur when so, guide portion is delivered in the heel of load driver pin.Guide portion can be arranged on function element main body place.In particular, guide portion can be connected with function element rigidly.
Other advantage is that the driving needle heel is connected with the function element main body by four joints (4-Gelenk).Can guarantee that thus the driving needle heel irrespectively has identical orientation all the time with its working depth.If driving needle heel has identical orientation all the time, then in the minimise wear of driving needle heel place.
