Description
Technical field
The present invention relates to a kind of double rib warp loom, this double rib warp loom has one first crochet hook needle-bar, one and the spaced apart second crochet hook needle-bar of this first crochet hook needle-bar, at least one sley bar, a traversing driving device, also has a continuous wobble drive mechanism, the sley point of described sley bar forms coil on two crochet hook needle-bars, described traversing driving device is producing a relative motion between sley bar and crochet hook needle-bar on the machine direction, described continuous wobble drive mechanism produces as the relative motion between sley bar and crochet hook needle-bar of oscillating motion continuously on a direction that makes sley point pass space between pin between the crochet hook.
Background technology
Generally make spacing knitwear (Abstandsgewirke) with double rib warp loom.Such tricot is made up of a preceding lining cloth face and a backsight cloth cover, and the former produces by means of the first crochet hook needle-bar, and the latter produces by means of the second crochet hook needle-bar.These two lining cloth faces by the spacing yarn, be also referred to as the end of a thread yarn and be connected.The spacing yarn is alternately guided two lining cloth faces into and is enrolled there by means of being fastened on sley point on the sley bar at this.
If sley bar should form coil on two crochet hook needle-bars, it repeatedly is controlled, make it in a pinhock circulation, must finish three continuous wobble cycle altogether, for this reason can be referring to DE 21 34 279 A1.At first in the centre between described two crochet hook needle-bars on the continuous axis of oscillation, wherein these two crochet hook needle-bars are on the knocking over position sley bar.At first carry out the offset movement of sley bar from described centre position, thereby make the crochet hook that be arranged on the other direction and arrive the sley bar position no longer be positioned under the sley bar at a first direction; Perhaps when using a plurality of sley bar, be positioned under the sley bar assembly.This position is essential for underlap.Needle-bar and therefore crochet hook just can rise, and carry out underlap simultaneously.
Carry out pin foremast yarn then, its method is to make sley point pass the swing of crochet hook needle-bar, until they are positioned at before the pinhock.It is traversing that the sley bar that should implement a kind of pin foremast yarn carries out side direction, just yarn placed below the pinhock doubling and swing to return on machine direction, and the sley bar with crochet hook begins to fall.After described sley bar knocking over, begin a kind of offset movement of sley bar again, so that make sley point enter into a underlap position favourable with respect to the second crochet hook needle-bar again.
This motion flow process of sley bar is subjected to the influence of a control device, and this device in fact must be to come work as the speed of three times on main shaft.In other words, when rotating 120 °, must realize by main shaft an oscillating motion continuously completely.Therefore a continuous oscillating motion of sley bar has three times fundamental frequency with respect to the speed of mainshaft.
This so realizes usually: a crank is linked to each other with machine shaft by a gearbox.This crank is controlled described continuous oscillating motion.Its rotating speed is three times of the speed of mainshaft.Thereby the sley point of sley bar just appears on the position very shortly, can implement transverse motion on this position, and not collide with crochet hook.This moment, sley bar was swung in the pinhock front with higher relatively speed, so that carry out pin foremast yarn.In fact must carry out to no time lag owing to return oscillating motion, it is very short therefore being used to make the traversing in time time interval of sley bar.Therefore certainly this requires sley bar that a very big acceleration is arranged on sideslip direction again, can make yarn place doubling below the hook of crochet hook by sley point.Thereby the quick transverse motion of necessity of described sley bar produces disadvantageous effect by high load to the jacquard weave transmission device when pin foremast yarn.
All of these factors taken together has all limited the operating rate of such warp knitting machine.
Summary of the invention
Task of the present invention is to drive a kind of double rib warp loom at a relatively high speed.
This task solves in a kind of warp knitting machine of the described type of beginning as follows: there is a cam in wobble drive mechanism, the described relative motion of the curve controlled of this cam continuously.
Use such cam just can no longer rely on a crank.A crank has been rotated with three times rotating speed.Or rather, described cam can drive with a rotating speed more less than crank, so the rotating speed of crank has no longer limited the operating rate of warp knitting machine.
Described curved surface preferably has three motion cycle (Bewegungszyklus).Can make cam with the rotating speed rotation identical in the case with main shaft.If be provided with more than three motion cycle, cam also can rotate more so.But when three motion cycle, realized a kind of gratifying rotary speed property.
Each motion cycle preferably has a shape different with sinusoidal shape.That just is no longer dependent on the continuous oscillating motion of controlling sley bar with a kind of sine-shaped shape.Or rather: can make sley bar move sooner during at a kind of sinusoidal shape in some scope internal ratios.Therefore a temporal deposit is just arranged in other scope, can make full use of this deposit, make sley bar move slowlyer herein.This can make full use of this point in the time of for example, is long time interval of transverse motion regulation of sley point.Correspondingly can make described acceleration necessary for a transverse motion of sley bar keep less, this just makes the load of machine generally speaking keep less.
Described motion cycle is preferably identical.This demonstrates superiority when making cam.Equally also simplified the assembling of cam in warp knitting machine, because can be free more on assembly method.
Cam more preferably has one at least and stops that portion's section-it has a predetermined length, stops in portion's section continuously speed of oscillating motion no better than zero at this.Described curved surface is controlled described sley bar, makes continuous oscillating motion that so-called interruption just take place when arriving a terminal location on some position.Here do not need absolute stopping certainly.A kind of motion slowly allows fully.But can use described dwell time, so that make sley point cause transverse motion.If can make the transverse motion of sley point and continuous oscillating motion remove coupling in this way, so just there is more method to make yarn be centered around crochet hook doubling on every side with higher reliability.
Between two motion portion sections that the portion section of stopping to be arranged in have the opposite direction of motion.Described stop segment just between two phase places of motion, makes sley point leave towards an extreme position or on by this extreme position in these two phase places.Here realized and a sinusoidal contrast: can prolong the described time interval greatly, described curved surface has its maximum in this time interval.
Described curved surface is more preferably at one 30 °, on the direction when 150 ° and 270 ° and at 90 °, and an extreme position of control sley bar on the opposite direction when 210 ° and 330 °.These angles relate to an original position, in the centre between described two crochet hook needle-bars on continuous swaying direction of sley bar on this position.
Described cam preferably has two chains of command, and they work on opposite driving direction.Cam makes sley bar produce forced guiding, thereby can make sley bar implement desirable continuous oscillating motion on each motion phase certainly, does not also need the external force that makes cam and sley bar maintenance effect that is for example caused by spring or like.Because needn't overcome this spring force, so it is just less to be used to drive the needed power of sley bar.
Each chain of command preferably with self a roller acting in conjunction.This makes the friction between cam and the sley bar less.
Particularly preferably make cam jar shape ground have a circumferential wall herein, one of them chain of command is formed on the medial surface of circumferential wall, and a chain of command is formed on the lateral surface of circumferential wall.Therefore guaranteed in a simple manner: each chain of command and a 's self roller acting in conjunction, and roller can not disturb or run on the other chain of command unintentionally with makeing mistakes mutually.
Description of drawings
Followingly in conjunction with the accompanying drawings invention is described according to a preferred embodiment.Shown herely be:
Fig. 1 to 11: different phase place in a braiding circulation.
The specific embodiment
A has partly represented a kind of guide bar controlling device by background technology in each accompanying drawing, and b partly represents the guide bar controlling device according to invention, and the c part has then been represented situation harmonious on knitting position, and this situation draws with two guide bar controlling devices.
Have a control lever 2 by a guide bar controlling device 1 of the present invention, it can be around an axis 3 with respect to support 4 swings of fixing with machine.Control lever 4 links to each other by a guide rod 5 and one group of sley bar 6,7, and these sley bars are synchronously motion all.Each sley bar has many sley points 8,9, and they are arranged perpendicular to plan in tandem.
Under sley point 8,9, be provided with two crochet hook needle-bars in the accompanying drawing, just preceding crochet hook needle-bar 10-it have behind many crochet hooks 11 and one crochet hook needle-bar 12-it have many crochet hooks of one in front and one in back arranging 13 perpendicular to plan.
Control device 1 has a cam 14, and it rotates around an axis 15.Axis 15 can be consistent with the axis of a main shaft 16, and cam 14 is just to rotate as main shaft 16 same speed so.This indicates with indication " 1X/ minute ".
Be provided with a circumferential wall 17 cam jar shape.Circumferential wall has an inner control face 18, is being glued with first roller 19 that is fixedly placed on the control lever 2 on this chain of command; Also have an outer chain of command 20, be glued with second roller 21 that equally also is arranged on the control lever 2 on this chain of command.When cam 14 rotates on arrow 22 directions, be counterclockwise in this case, that is to say control lever 2 is swung back and forth around axis 3.This motion this by described two chains of command 18,20 with the acting in conjunction of described two rollers 19,21 forced guiding.That is to say that cam 14 acts on control lever 2 on two opposite directions of motion.
A kind of control device 100 by background technology equally also has a support 104 that is fixed on the machine, and main shaft 116 is bearing in this support.Make this main shaft 116 drive a driving shaft 122 by a gearbox that is not shown specifically with three times rotating speed.On this driving shaft 122, be fixed with a guide rod 105, two sley bars 6,7 as described in this guide rod acts in the 5 identical modes of the crank shown in Fig. 1 b by a crank 123.
Because by the driving of crank 123, sley bar 6,7 has just been realized a kind of continuous oscillating motion of sinusoidal shape when driving by control device 100, that is to say sley bar 6,7 is moved continuously.Be one immediately after the deflection on an extreme position and return oscillating motion.(this moment, sley point 8,9 should make yarn center on crochet hook 11,13 doublings) has only few relatively time available correspondingly on an extreme position.
Can force motion of generation by means of cam 14, this motion is different from sinusoidal shape.Motion between two maximum deflections of sley bar 6,7 can be carried out quickly, thereby on extreme position, have the more time available.Can make sley bar in the described time is not swingingly moving continuously, just can realize transverse motion so herein and is not subjected to the interference of swing continuously.
Motion process should at length be illustrated by Fig. 1 to 11.
Fig. 1 represents the starting point of a motion cycle of sley bar 6,7.Use " 0 ° " expression beginning angle herein.Sley bar 6,7 is positioned on the centre position.If below speak of directioin parameter or location parameter, these parameters just are meant continuous swaying direction so, that is to say that sley point 8,9 is with respect to crochet hook 11,13 in the drawings from right to left or a kind of relative motion from left to right.
Set out by centre position shown in Figure 1, wherein before just in time knocking over of crochet hook needle-bar 10, sley bar 6,7 swings on the deviation post above preceding crochet hook needle-bar 10, thereby makes the crochet hook 13 of back crochet hook needle-bar 12 have an opportunity to rise.This position reaches (Fig. 2) in the present invention in the time of 30 °.This position has just reached in the time of 13 ° in background technology.All angle parameters all relate to the rotation of main shaft.
And then described pin foremast yarn returns sley bar 6,7 swings.Simultaneously sley point 8,9 is guided through space between other pin between the crochet hook 13.Sley bar in the direction swing towards opposed crochet hook needle-bar 10, then is rocked to original original position (centre position of sley bar 6,7) on an offset position (Fig. 5) on the centre position, it is positioned on the about 180 ° angle position (Fig. 6).Knocking over takes place in back crochet hook 13 on this position.
6,7 of sley bars are realized an offset movement on other direction, so that crochet hook needle-bar 12 can lift (Fig. 7) before making.The described extreme position that the time occupies in skew reaches during in the present invention at 210 °.This angle is 193 ° in background technology.
Sley bar 6,7 is just swung forward and is passed crochet hook needle-bar 10 (Fig. 8) then, thereby (Fig. 9 b) just discharging in front (Fig. 9 c) when angle position is 270 °. Sley bar 6,7 at the laterally offset hand-manipulating of needle foremast yarn of going forward side by side, wherein makes yarn doubling below the pinhock of crochet hook needle-bar 12 again on this position.
Whole braiding process realizes that wherein the continuous oscillating motion of sley bar 6,7 is just controlled by unique complete rotation of cam 14 when machine shaft 16 rotations one whole circle.
The cam curved surface that is made of inner control face 18 and outer chain of command 20 has carried out optimization like this, with so that sley bar 6,7 and crochet hook 11, relative motion between 13 obtains cooperation, thereby lag behind and acceleration just can be realized sley bar 6 with corresponding in the desirable time, 7 and needle- bar 10,12 between motion process.Thereby a kind of continuous oscillating motion that can be intervened influence that has produced sley bar.
