Description
Technical field
The present invention relates to a kind of warp knitting machine of the sinker holding that has the knitting needle that can rotate around the axis of a knitting needle fulcrum by the needle stand bar and can rotate around the axis of a sinker fulcrum by the sinker bar.
Background technology
For example, German patent DE-PS 608003 discloses a kind of such warp knitting machine., so select a shaft position here, promptly work as each rod member such as needle stand bar and sinker bar and in common knitting work, neither produce collision, otherwise be not in the way again.
German patent DE-PS 1760140 discloses another such warp knitting machine.Here, in fact the sinker holding that is combined into one with knocking-over sinker carries out horizontal movement, and knitting needle compares with it and moves more suddenly.The knitting needle fulcrum can rotate around same axis with a pusher jack fulcrum, and pusher jack is fixed on this pusher jack fulcrum by a pusher jack bar.
DE-OS 44 05 793 describes another warp knitting machine with needle stand bar and sinker bar.The control of the crank mechanism that these bars are subjected to, this crank mechanism is connected with these bars by push rod.In known loom, the space, position of the position of needle stand bar fulcrum and sinker bar fulcrum must be far away, its reason is, because of the occupation of land of the needle stand of fixing knitting needle on it requires to leave less free space, thereby these control positions are far from swivel point.Especially on sinker bar swivel point, find such situation.
This has two shortcomings, and a shortcoming is exactly that it is enough big that the size of sinker bar must keep, to shorten the distance from the fulcrum to the control point.This causes the bar mass ratio bigger again, and this has a negative impact to loom running work.
Another shortcoming is, because the distance from the swivel point to the control point is bigger, so the sinker motion can only be a near linear, such motion is restricted to seesawing in a horizontal plane basically.Because knitting needle must carry out bigger stroke, so this has limited the operating rate of loom.
Summary of the invention
Task of the present invention is to improve the operating rate of warp knitting machine.
This task is to solve like this in the warp knitting machine of the above-mentioned type, and promptly movement locus at least a portion of sinker holding and knitting needle movement locus double team go out an angle that is 45 ° to the maximum.
Realized having a component opposite with the knitting needle direction of motion at the movement locus of this sinker holding that also can be combined into one with knocking-over sinker by this embodiment.When sinker holding was positioned on the knocking over position, this was a particularly suitable.Promptly in this case, sinker holding can react on knitting needle.Thus one, both shortened the knitting needle move distance, shorten the sinker move distance again.Certainly, the move distance of loop-forming element is short more, and required time is corresponding short more.Thereby loom can turn round more quickly.
Sinker holding leads on a circular trace and moves, and this circular trace goes out an angle that is 45 ° to the maximum with knitting needle movement locus double team in whole range of movement.Guaranteed that thus the sinker holding and the knitting needle direction of motion double team that are positioned at the knocking over position go out an angle that is significantly less than 45 °.Be that convenient sinker holding and knitting needle are not accurately to move mutually, but when in its motion process, always having certain differential seat angle, by the way, can say to a certain extent still and add the motion of going up sinker holding and knitting needle that this can cause the further shortening of stroke.
The sinker bar preferably has a length, and wherein, the distance between sinker fulcrum and sinker holding is 100 millimeters to the maximum.This has two advantages, and one is only having under 100 millimeters closely spaced situations, can make movement locus accurately finish the circular motion that radius has only 100 millimeters.This circular motion can arrange like this, and promptly in knocking over moment, sinker movement locus and knitting needle movement locus double team go out required smaller angle, thereby make sinker and knitting needle with bigger component motion relative motion, so that shorten stroke separately.Another advantage is that less sinker bar also has corresponding less quality, thereby can make the faster acceleration of sinker bar.The noise that produces in operation process can remain on reduced levels.Experimental result shows, by being adapted as short sinker bar and moving downward when the knocking over, revolving speed of knitting machine can be brought up to 3800U/ minute from 3300U/ minute.Obviously little noise is arranged under the same rotational speed condition.In other words, now, people are with about 3700U/ minute speed running loom, so that obtain and same noise level when before being about 3.300U/ minute.
On the knocking over position of sinker holding, a line between sinker holding and sinker fulcrum preferably and knitting needle direction of motion double team go out an angle that is at least 50 °.When 45 ° of angles, the component motion of sinker holding and the knitting needle direction of motion have such part on the contrary, promptly this part equal sinker holding motion the secondary square root doubly.Angle is big more, and then this component motion part is big more.But, because between knitting needle motion and sinker motion, there is the danger of conflict, so angle not should be 90 °.Thus, preferred 50 °-Yue 70 ° angle.
Sinker fulcrum and needle stand fulcrum preferably are arranged in the horizontal plane.Significantly shortened distance thus from fulcrum to sinker bar control point.This means that also the size of sinker bar can be very little, and this causes littler quality and and then higher operating rate.
The excellent shape that preferably is arranged to double armed lever of sinker bar.One of them bar can be used to guide sinker, and another bar is used to act on a push rod.This has just enlarged controllability.
In addition, the length of two of the sinker bar effecive lever arms preferably differs each other and is 20% to the maximum.We can say that also these two lever arms can be equally long.This transmission to power is favourable.
Description of drawings
Below, in conjunction with the accompanying drawings to a preferred embodiment of the present invention will be described in detail, wherein:
A unique width of cloth accompanying drawing is the schematic diagram of a warp knitting machine part.
Concrete form of implementation
One warp knitting machine 1 has a plurality of 2,3 and knitting needle seats 5 that are fixed on the needle stand bar 6 of sley bar that are fixed on the sley bar bar 4.Knitting needle seat 5 and needle stand bar 6 are shown in dotted portion.On knitting needle seat 5, be fixed with a plurality of knitting needles 7.Needle stand bar 6 can rotate around the axis 8 of a knitting needle fulcrum 9.Because knitting needle 7 is longer to the distance of axis 8, so the motion of knitting needle 7 almost is linear.
On a sinker bar 10, be provided with a plurality of sinker holdings 11.Because these sinker holdings 11 are arranged before and after on the direction of pointing to figure plane, therefore only can see a sinker holding in the drawings.Sinker bar 10 is fixed on the sinker bar 12 that can rotate around the axis 13 of a sinker fulcrum 14.The shape of 12 one-tenth double armed levers of sinker bar, it has first lever arm 15 and 16, one push rods 17 of one second lever arm that are fixed on the sinker bar 10 to act on second lever arm 16 on a control point 18.
Only be about 100 millimeters at the axis 13 of sinker fulcrum 14 and the distance X that becomes to grip between the sinker holding 11 of knocking-over sinker sub-assembly form.Because sinker holding 11 has certain development length, so measure this distance just based on a point on sinker holding 11, this is corresponding to the operating point of knocking over position.
Because shorter to the distance the sinker holding 11 from the axis 13 of sinker fulcrum 14, therefore, sinker holding 11 has one and the corresponding movement locus 19 of circular trace.At this, arrange fulcrum 14 like this, promptly on each section of movement locus 19, movement locus 19 and knitting needle 7 approximate is linear movement locus double team, and to go out one be 45 ° angle α.If can not be observed this condition in whole movement locus scope, then this less angle α at least also is applicable to the knocking over position.So accomplish this point by plain mode, promptly sinker fulcrum 14 and knitting needle fulcrum 9 are disposed generally in the horizontal plane with its axis 13,8.At this, sinker fulcrum 14 is relative 11 horizontal staggering of sinker holding in the horizontal direction, thereby make the sinker holding 11 and the line 20 of sinker fulcrum 14 axis 13 go out one 45 ° angle β with knitting needle 7 direction of motion double teams.This is applicable to the knocking over position too.
The result of this layout is that the movement locus 19 of sinker 11 has a component opposite with the knitting needle direction of motion when knocking over.In other words, knitting needle 7 and sinker holding 11 relative motions.Shortened the movement travel of knitting needle 7 and sinker holding 11 thus.If move distance is shorter, then the used time of its return is also shorter.Loom can turn round at a relatively high speed.
In addition, sinker bar 12 is relatively lacked by distance X and can be designed to less quality.Correspondingly, the acceleration of sinker holding 11 needs less power.So just reduced wearing and tearing, made machine obtain higher running speed simultaneously.Because push rod 17 is set on another lever arm 16 as sinker bar 10,, reduce the quality of sinker bar 12 simultaneously so also can shorten the distance between sinker fulcrum 14 and the control point 18.
Two lever arms 15,16 of sinker bar 12 are isometric basically, and its difference in length is 20% to the maximum.This has produced favourable control characteristic.
Certainly, warp knitting machine 1 also has other parts, as being bearing in eye needle guide 30 or pusher jack 40 on the pusher jack bar 41 rotationally around pusher jack fulcrum 42.But for the sake of clarity, these parts are only schematically illustrated in the drawings.
