Description
The present invention relates to a kind of locking device that is used for being arranged on swingably the reel cage on the fixing bearing in position in the drafting device for spinning machine, it has an action bars that opens and closes reel cage, and this action bars is connected with bearing by a curved bar.
It is this that to comprise the retaining mechanism at band reel cage of action bars and the curved bar between the bearing known.That is, be supported on the bearing to the rotatable and fixed-site of toggle-lever arm, another toggle-lever arm is supported on reel cage or the action bars.Therefore only deflection respect to one another may appear between two toggle-lever arms when opening reel cage.A kind of like this curved bar is described in the time of for example in German patent specification DE-PS1087944.
Task of the present invention provides a kind of reel cage locking device with the curved bar system, and this curved bar system allows to make more favourable power-Stroke Control than known locking device.
According to the present invention, begin part for this specification this class locking device is provided, this task is to solve like this: first toggle-lever arm of this curved bar is fixedlyed connected with action bars, and second toggle-lever arm that is guided by spring is with rotationally and make restricted mobile mode with respect to bearing and be bearing on the supporting member that is arranged on the bearing.By means of this, this second toggle-lever arm does not have the point of fixed-site in its whole movement travel.Therefore allow to realize the conversion ratio more much higher, operating physical force is diminished when opening or closing reel cage than known schemes.Like this, the conversion of the curved bar moving region of adaptive zone high capacity and low load without a doubt.Perhaps, under identical change over condition, can reduce scantling with respect to known schemes.Like this, retaining mechanism occupies less installing space.In this case, the supporting member on the bearing can be made of one or more bearing pins that are positioned on the rolling curve.The marquis rolled on supporting member when like this, this second toggle-lever arm had at least between its moving period.So each parts that constitute this supporting member have constituted the guiding curve of second toggle-lever arm in the subregion of separately movement travel.This toggle-lever arm also can roll on the spinning machine pole at hold-down support between its moving period, thereby this pole also can be by the purposes curve track.As hoping reel cage not have the middle position of having a rest temporarily really,, crossed the dead point of curved bar then in the reel cage closed position.Yet if also do not cross the dead point, the dead-centre position of reel cage just becomes the position of having a rest temporarily, a stable centre, and this position is as the part loading position.In addition, the configuration of curved bar can be selected like this, makes open (at the self-retention area operation) of reel cage finish in the mode of partial buffer at least.So, especially in having the high draft device of high torque (HT), allow when the operation locking device, to improve comfortableness.In addition, in the reel cage fully open position, the guiding groove on the curved bar engages a pin that is arranged on the bearing, thereby guarantees that reel cage is positioned at this position.In the project organization of a locking device that is particularly conducive to assembling, first toggle-lever arm is made of the part of action bars.Can reduce the quantity of parts thus.In addition, reel cage can be nibbled bearing from external rings, to guarantee promptly to assemble locking device.
Be explained in detail by the preferred forms of accompanying drawing below locking device of the present invention.
Fig. 1 is the side view of reel cage (non-loaded parts and cover plate) when being positioned at the closed position that has locking device.
View when Fig. 2 has a rest the position temporarily for reel cage shown in Figure 1 is positioned at a centre.
Situation when Fig. 3 is positioned at the fully open position for reel cage shown in Figure 1.
Fig. 4 is the detail drawing of a toggle-lever arm.
Fig. 5 is the detail drawing of one second toggle-lever arm.
Fig. 1 illustrates the reel cage 10 of a band action bars 11, and this action bars is equipped with a handle 12 at its front end, and is bearing on the reel cage body 14 in the mode that can do restricted swing by a bearing pin 13.This reel cage body 14 is bearing on the bearing 16 of fixed-site swingably by a bearing pin 15 again, and this bearing is installed on the pole 17 of spinning machine.Action bars 11 is connected with bearing 16 by a curved bar 18.In this case, curved bar 18 is made of first toggle-lever arm 19 of fixedlying connected with action bars 11 and one second toggle-lever arm 20.This second toggle-lever arm 20 constitutes with two parallel connecting plates as shown in Figure 4, and fixedlys connected with first toggle-lever arm by a hinge 21.Second toggle-lever arm 20 has a confession and is fixed on the hole 22 (Fig. 4) that the bearing pin 23 on the bearing 16 passes.When reel cage 10 was in closed condition, second toggle-lever arm 20 also was supported on another bearing pin 24 of bearing 16 with a recess 25 that is arranged on its circumferential profile.In the process that rocking bar 10 is opened, second toggle-lever arm also rolls on the 3rd bearing pin 26 with second recess 27 of its circumferential profile, as Fig. 2 and shown in Figure 4.Thereby these three bearing pins 23,24 and 26 constitute the supporting member (Gegenlager) of this curved bar 18 together.In this case, second toggle-lever arm 20 is not fixed with respect in these three bearing pins any one, and it can not only self rotate during reel cage is opened, and can do restricted moving with respect to bearing 16.As shown in Figure 3, second toggle-lever arm 20 no longer contacts with bearing pin 24 and 26 in rocking bar 10 full open position.In addition, it not only rotates (corner is greater than 90 °) with respect to bearing pin 23, also is moved to the left.This motion arrangement on bearing 16 can realize the transformation relation of very favourable curved bar 18 by second toggle-lever arm 20.For second toggle-lever arm 20 can be returned, between the bearing pin 23 of two connecting plates of this toggle-lever arm 20 and bearing 16, be provided with a spring 28.To this, these spring 28 curved two boss 29 (Fig. 3 and Fig. 5) of walking around on the toggle-lever arm 20, its free end forms a U-shaped, and this U-shaped end of spring 28 is directed into through on the bearing pin 23 of bearing 16.Like this, when opening reel cage 10, spring 28 can be tightened fully along with the motion of toggle-lever arm 20.When reel cage 10 was in closed condition, the inside hole 22 that constitutes bearing pin 23 link stoppers in second toggle-lever arm 20 made spring 28 unlikely too stretch (Fig. 1).
Closed position at reel cage shown in Figure 1 10, curved bar 18 is positioned near outside its dead point, that is to say that the hinge 21 between the toggle-lever arm 19 and 20 is the right side of imaginary line between supporting shaft (Lagerbolzon) 13 and supporting member bearing pin (Gegenlagerbolzen) 24 and then.Different therewith, the position of having a rest temporarily, the centre that Fig. 2 has provided reel cage 10 when arriving curved bar 18 dead points.Curved bar hinge 21 just in time rolls on supporting shaft 23 at this motor segment second toggle-lever arm 20 on the supporting shaft 13 and the right side that becomes the imaginary line between the supporting shaft 23 of supporting member this moment.At the state that reel cage 10 shown in Figure 3 is opened fully, supporting shaft 23 enters in the groove 30 that is arranged on first toggle-lever arm 19, thus reel cage 10 is stuck in this position.
The inside hole 22 of second toggle-lever arm 20 needs not to be the hole that all sides is all shut.Can also realize toggle-lever arm like this, the recess 22 that one one side of one of them connecting plate 20 ' have is as shown in Figure 5 opened wide '.Because this toggle-lever arm 20 or 20 ' when opening reel cage 10, at first on two supporting shafts 24 and 26, roll, recess 22 ' open design for as enough along the guiding area of bearing pin 23.
