Summary of the invention
The object of the invention is to, a kind of sinker is provided, it is the transmission foot of enhanced feature parts reliably, can prevent reliably that again transmission foot is inadvertently deposited in functional part bed.In addition, will actuate when needed functional part, its transmission foot is joined in cam base plate with less degree.
This object is achieved by a kind of sinker for knitting machine functional part, wherein utilize sinker can make the transmission foot being deposited in functional part bed of functional part rise to functional part bed top, it is characterized in that, utilize this sinker can at least two different height, be formed for the functional part substrate of functional part, utilize this functional part substrate can prevent that the transmission foot of functional part is deposited in functional part bed.
Sinker of the present invention thereby can form a kind of functional part substrate, functional part can be along this functional part basesliding when particularly at it, in functional part groove, rollback moves, and this functional part substrate prevents transmission foot sedimentation under the axial load impact of functional part.Meanwhile, sinker is responsible for mentioning reliably the transmission foot of functional part, this transmission foot is clamped by the triangular portions of knitting system, and can be completed a kind of required function, as lopping, pad are put tuck, time-out be not touched position (adapter ring) or barring-on.Functional part preferably can only have a unique transmission foot.
As functional part, for example, can consider to adopt another parts of knitting needle, needle selection part or knitting machine.Sinker can be lifting sinker or needle selection sinker, and this sinker is being touched stroke in the direction backing plate (Auflage) as transmission foot on variable height according to it.So just can make transmission foot engage from different cam tracks at various height.Can realize thus a kind of three process technology (not braiding-coil-tuck, or barring-on-adapter ring-be failure to actuate).Can save pressing technology (Dr ü ckertechnik).Sinker can be realized with less length and simple structure, and this has saved manufacturing cost.Functional part bed can be for example needle-bar.
Further advantageously, transmission foot can overcome the elastic force being applied to it and mentioned by sinker.So reverting to its position being deposited in functional part bed, transmission foot needn't be undertaken by sinker or another parts.Or rather, this recurrence is carried out passively by the elastic force that preferably can be produced by functional part itself.
In the time of design sinker, can consider to adopt various scheme.
A kind of scheme is that sinker can be moved linearly and is arranged in functional part groove.Sinker is moved towards functional part, can utilize thus sinker section that transmission foot is mentioned, and can highly particularly on the first height, form functional part substrate at least one.Thereby as long as sinker remains on the position that it is pushed ahead, it just forms the inadvertently knitting needle substrate (Nadelgrund) of sedimentation of transmission foot that can prevent functional part.Thereby by unique once motion of sinker, just can realize two kinds of functions, mention transmission foot and form functional part substrate.Here further advantageously, can utilize angle to make sinker return back to its intact original position.This rollback motion can be carried out in the time that correlation function parts finish through the process of triangle (Schlossdurchgang).The transmission foot of functional part can be deposited in functional part bed thus again.Make sinker in the axial direction in diverse location, just can realize the functional part substrate in differing heights.
But sinker is also arranged in functional part groove swingably.In this case, the transmission foot of functional part can be mentioned by the oscillating motion of sinker, can form functional part substrate simultaneously.Particularly can make sinker swing around its axle, utilize thus lifting fin transmission foot can be mentioned, and can at least one height, form functional part substrate.Here, if even if sinker also acts on the transmission foot region of functional part below in its intact original position, without doing rectilinear motion.So sinker does oscillating motion to be just enough to mention transmission foot, can to form again and can prevent the inadvertently functional part substrate of sedimentation of transmission foot.Make sinker in different swing position, just can realize the functional part substrate of differing heights.
According to this design, the power that sinker can utilize transmission foot or utilization to be applied to it return back to its intact original position.So only need just actuate on one's own initiative sinker in the time mentioning transmission foot.
Swing but also can allow sinker to overcome in one direction elastic force, or can regulate height.So, only need or overcome elastic force on a swaying direction and actuate on one's own initiative sinker.According to this design, sinker revert to its intact original position can be undertaken by elastic force, carries out passively.
Can assign to guide sinker along guide portion.This leader particularly can have control curve, and this control curve and certain guiding piece for example guide wire rod mating reaction.
Sinker and functional part can be arranged in a common groove of functional part bed, or are arranged in different beds.
A kind of knitting machine, has functional part bed, is arranged in functional part and sinker of the present invention in the functional part groove of this functional part bed, and this knitting machine also falls within the scope of the present invention.
Detailed description of the invention
Fig. 1 a to 1f is the cutaway view in functional part groove 110 regions of functional part 100, is provided with the functional part 10 and the sinker 11 that are designed to knitting needle in this functional part groove.Cover rail 120 prevents that the functional part that functional part 10 is adjacent from deviating from together from needle tray 110, and the sinker that cover rail 130 settlement prevention sheets 11 are adjacent is deviate from together from needle tray 110.Functional part groove has the notch 19 that is arranged in functional part substrate 115.Sinker 11 is supported on cover rail 130 by elastic component 11.1.
In Fig. 1 a, no matter functional part 10 or sinker 11, all in its intact original position.Sinker 11 moves backward by angle 12.The pinhock 13 of functional part 10 is positioned at the position (Kammgleicheposition) of neat and well spaced alignment.Functional part 10 has the elastic segments 14 being positioned in functional part main body 15 at its Background Region, be provided with the transmission foot 16 of functional part 10 in the rear end of this elastic segments.Elastic segments 14, to lower compression transmission foot 16, is pressed against this transmission foot and is arranged on the slope 17 or inclined-plane 17` or 17`` of notch 19 of the functional part substrate 115 of functional part bed 100.
If now a power is applied to towards the direction of arrow 18 on the angle 12 of sinker 11, as shown in Figure 1 b, the transmission foot 16 that sinker 11 will promote functional part 10 moves forward.In this case, transmission foot 16 is upward sliding on slope 17, causes from functional part bed 100 and mentions a segment distance.Now, this transmission foot can be clamped by triangular portions unshowned, that move to functional part bed 100 tops here.Sinker 11 is in the position before slope 17.1 shown in Fig. 1 b.Mobile if sinker 11 continues towards the direction of arrow 18, this sinker is simultaneously along slope 17.1 upward slidings, thus by transmission foot 16 from functional part bed jack-up, until this transmission foot engages completely, (Fig. 1 is c).Can make functional part 10 for example in the very out position shown in Fig. 1 d by means of triangular portions.During functional part is so mobile, sinker 11 is in remaining on its forward position, in this position, the section 11a of this sinker forms the functional part substrate in the first height, this functional part substrate shelters from notch 19, and almost transits to functional part substrate 115 in the front area of functional part bed 100 tight.Thus in the time of functional part 10 rollback, as shown in Fig. 1 e, the transmission foot 16 of functional part 10 can be along the functional part basesliding being made up of section 11a, and can carefully be deposited in functional part bed.Only have and utilize the angle 12 of sinker 11 to make on one's own initiative this sinker return back to the original position shown in Fig. 1 a, could transmission foot 16 is deposited in functional part bed 100 again by the elastic segments of functional part 10 14.Thereby this design based on sinker 11, there will not be for example situation of sedimentation inadvertently due to the axial load of functional part 10 of transmission foot 16 here.
Shown in Fig. 1 f, sinker 11 in the corresponding position of Fig. 1 b, in this position, this sinker promotes forward towards the direction of arrow 18, but still is pressed against on inclined-plane 17`.This means, the height of the end face of section 11a is less than Fig. 1 e.Transmission foot 16 projects upwards in the distance of functional part bed 100 therefore smaller.But section 11a has formed again functional part substrate, be in the second height specifically.So in the time of functional part 10 rollback, as shown in Figure 1 f, the transmission foot 16 of functional part 10 is along the functional part basesliding being made up of section 11a, and can carefully be deposited in functional part bed 100.Only have and utilize the angle 12 of sinker 11 to make on one's own initiative this sinker return back to the original position shown in Fig. 1 a, could transmission foot 16 is deposited in functional part bed 100 again by the elastic segments of functional part 10 14.
Utilize elastic segments 11.1 to guarantee that sinker 11 is all pressed downwardly onto in functional part bed all the time.
Fig. 2 and Fig. 1 f are basic identical.But in this case, functional part 20 is two modular constructions.The transmission foot 26 of this functional part is arranged on the swing component 25 hinged with functional part bar 21.Functional part bar 21 has elastic segments 24 in its back-end, and the free end of this elastic segments is inserted in transmission foot 26.Elastic segments 24 is responsible for making the transmission foot 26 of functional part 20 to be deposited in functional part bed 100 in the intact original position of functional part 20.
Fig. 3 a ~ 3f is the cutaway view in the functional part groove region of functional part bed 100`, is furnished with the sinker 30 of the second embodiment and the functional part 40 of one in this functional part groove.Functional part 40 also has elastic segments 44, and transmission foot 46 is placed in the rear end of this elastic segments.Sinker 30 can swingingly be placed in functional part groove around axle 31.This sinker also has lifting fin (Hebeschwinge) 32, and this lifting fin acts on (untergreifen) below in the transmission foot 46 of functional part 40.This sinker also disposes and activates fin 33, can make sinker do oscillating motion by this actuating fin.In the intact original position of sinker 30, lifting fin 32 is pressed against on the bottom of the notch 19` in functional part bed 100`, in other words, activates fin 33 and is supported on cover rail 130.The transmission foot 46 of same intact functional part 40, and then is deposited in functional part bed 100` to lower compression by elastic segments 44.
Press and activate fin 33 towards the direction of arrow 34, just can make sinker 30 swing, as shown in Figure 3 b, so sinker utilizes its lifting fin 32 that the transmission foot of functional part 40 46 is risen to functional part bed top, thereby this transmission foot can be clamped by the triangular portions of knitting system.Next make functional part 40 for example endure out for lopping, this is shown in Fig. 3 c.Before this, push moving during, can keep being applied to towards the direction of arrow 34 the power effect activating on fin 33, thereby lifting fin 33 shelters from the notch 19` in functional part bed 100`, and forms functional part substrate 115``.
But before knitting needle 40, push moving during, do not need lifting fin 32 to form functional part substrate, because the transmission foot 46 of functional part 40 is supported on functional part substrate 115` in the front area of functional part bed 100`, therefore can't inadvertently be deposited in functional part bed.So front push also can termination during moving to the power effect activating on fin 33, thereby lifting fin 33 again can be to lower swing.
But between rollback moving period of knitting needle, lifting fin 32 is mentioned again, this is shown in Fig. 3 d.
Because the elastic segments 44 of transmission foot 46 is to pressing down, therefore in the time that functional part 44 does rollback motion, if make transmission foot 46 remain on the state of mentioning, just must utilize the masterpiece being applied on actuating fin 33 to be used for making the lifting fin 32 of sinker 30 to mention.
Under the situation shown in Fig. 3 e, f, sinker 30 is according to the swing position of Fig. 3 a with according to the swing position between the swing position of Fig. 3 b.Form functional part substrate 115``` by lifting fin 32, this functional part substrate is disposed generally on the below of functional part substrate 115`.So in another working depth, particularly projecting upwards in the distance of functional part bed 100`, transmission foot 46 is less than Fig. 3 c, 3d.
Figure 4 illustrates the corresponding situation with Fig. 3 f, wherein have sinker 30 and according to the functional part 20 of Fig. 2.The transmission foot 26 of functional part 20 is arranged on swing component 25.Swing component 25 is hingedly arranged on functional part bar 21, and under the relaxed state of elastic segments 24 by the elastic segments 24 of functional part bar 21 to lower compression.Transmission foot 26 is positioned at the top of functional part bed, and then can be clamped by triangle.But transmission foot 26 protrudes from the distance of functional part bed large unlike the situation shown in Fig. 3 d for example.This is because sinker 30 mediates, lifting fin 32 thereby form functional part substrate on lower height.
From Fig. 3 e, 3f, rotating sinker 30 together rotates according to sinking depth in kinking process, to make the jointing altitude of functional part keep constant.
Fig. 5 a ~ 5f shows the sinker 60 of another kind of design, and this sinker can be arranged in the functional part groove of functional part bed 100` rotationally around axle 61 equally.This sinker here with knitting needle 40 mating reactions of Fig. 3.This sinker is different from sinker 30, except lifting fin 62 and actuating fin 63, also has elastic component 64, and this elastic component forces lifting fin 62 in the position to lower swing shown in Fig. 5 a.So 44 need of elastic component of functional part 40 are deposited in functional part bed 100` the transmission foot 46 of this functional part.If mention transmission foot 46, just towards the direction of arrow 66, a power is applied to and activates on fin 63, as shown in Figure 5 b.Therefore, only a power need be applied on sinker, to mention lifting fin.Fig. 5 b ~ 5d is compared with Fig. 5 f known, lifting fin 62 upper formation functional part substrate at various height.
Figure 6 illustrates the corresponding situation with Fig. 5 f, wherein have sinker 60 and according to the functional part 20 of two modular constructions of Fig. 2.
In Fig. 7 a, no matter functional part 10 or sinker 70, all in its intact original position.Sinker 70 moves to terminal location below by angle 71.Utilize guiding wire rod 72,73 to fix the height of sinker 70, guiding wire rod passes the leader 74,75 of the control curve form of sinker 70, and is fixed in functional part bed.Leader 74,75 has section 76,77 and section 78,79, and the installation position of section 78,79 in sinker 70 is lower than section 76,77.In the time that sinker 70 does rectilinear motion, this sinker can be in different height levels.The pinhock 13 of functional part 10 is positioned at the position of neat and well spaced alignment.Functional part 10 has the elastic segments 14 being positioned on functional part bar 15 at its Background Region, be provided with the transmission foot 16 of functional part 10 in the rear end of this elastic segments.Elastic segments 14, to lower compression transmission foot 16, is pressed against this transmission foot and is arranged on the slope 17 or inclined-plane 17` of notch 19 of the functional part substrate 115 of functional part bed 100```.
If now a power is applied to towards the direction of arrow 18 on the angle 71 of sinker 70, as shown in Fig. 7 b, the transmission foot 16 that sinker 70 will promote functional part 10 moves forward.In this case, transmission foot 16 is upward sliding on slope 17, causes from functional part bed 100``` and mentions.Now, this transmission foot can be clamped by triangular portions unshowned, that move to functional part bed 100``` top here.In the position shown in Fig. 7 b, the distance that sinker 70 moves towards the direction of arrow 18 should make its leader 74,75 still on the height level of the section 76,77 in leader 74,75.If it is mobile that sinker 70 continues towards the direction of arrow 18, section 78,79 moves through guiding wire rod 72,73, sinker 70 is mentioned slightly, and then transmission foot 16 is mentioned slightly.Make thus transmission foot 16 arrive higher working depth.
Can make functional part 10 for example in the very out position shown in Fig. 7 d by means of triangular portions.During functional part is so mobile, on the position that sinker 70 pushes away, mentions before remaining on it, in this position, the section 70a of this sinker forms the functional part substrate in the first height, this functional part substrate shelters from notch 19, and almost transits to functional part substrate 115a in the front area of functional part bed 100``` tight.Thus in the time of functional part 10 rollback, as shown in Fig. 7 e, the transmission foot 16 of functional part 10 can be along the functional part basesliding being made up of section 70a, and can carefully be deposited in functional part bed.Only have and utilize the angle 71 of sinker 70 to make on one's own initiative this sinker return back to the original position shown in Fig. 7 a, could transmission foot 16 is deposited in functional part bed again by the elastic segments of functional part 10 14.Thereby this design based on sinker 70, there will not be for example situation of sedimentation inadvertently due to the axial load of functional part 10 of transmission foot 16 here.
Than Fig. 7 e, sinker 70 is sedimentation slightly again in Fig. 7 f.This means, the section 76,77 of leader 74,75 has moved through guiding wire rod 72,73, that is guiding wire rod 72,73 is arranged in the section 76,77 of leader 74,75.It is upper that transmission foot 16 is positioned at sinker section 70a, so form the functional part substrate in lower height by this sinker section.This means, transmission foot 16 projects upwards in the distance of functional part bed less, so can clamped by other triangular portions in some cases.
Fig. 8 is similar to Fig. 7, and difference is, also shows here according to the functional part 20 of two modular constructions of Fig. 2.
The transmission foot 26 of functional part 20 is arranged on swing component 25.Swing component 25 is hingedly arranged on functional part bar 21, and under the relaxed state of elastic segments 24 by the elastic segments 24 of functional part bar 21 to lower compression.Transmission foot 26 is positioned at the top of functional part bed, and then can be clamped by triangle.But transmission foot 26 protrudes from the distance of functional part bed large unlike the situation shown in Fig. 7 d for example.This is because sinker 70 is in position below, thereby forms functional part substrate on lower height.
