Description

Knitting machine

Technical field

The present invention relates to a kind of knitting machine, have at least one needle-bar, can carry insert particularly knitting needle in its needle track with vertically moving, wherein, insert has lock face, and this lock face is not protruding from needle-bar end face when not choosing insert.

Background technology

By promoting the transmission heel of insert, pin heel can to the trigonometric curve of knitting system (Schlosskurve) interlocking corresponding with the distribution of trigonometric curve seesaw in needle track. According to transmission heel on which time point from needle-bar promote, it can be caught by different trigonometric curves, thus can with realize so-called frequency multiplexing technique. If insert is knitting needle, then knitting needle forms coil or tuck in the book according to the trigonometric curve catching transmission heel. If not lift pins heel, then it is maintained at unactivated sinking in position. For making transmission heel sink to needle-bar, thus insert is not moved by knitting system, for instance known so-called pressure triangle. This triangle is utilized the transmission of knitting needle to be called in person press-in needle-bar on the time point determined also thus departing from the Qian He with triangle. Then promoted the transmission heel of knitting needle or other inserts on the contrary by triangle or other inserts for promoting triangle. At triangle by after (Schlossdurchgang), transmission is called in person or activates, or by spring force pressure back stitching bed.

Because pressure trigonometric sum promotes relative complex on three-legged structure, so also proposed the triangle with different activationary time point, wherein the optional feature being connected with knitting needle form fit being sent in the position of tensioned and fixing. Cancelling this fixing on the time point of the determination passed through at triangle, thus the transmission heel of knitting needle carries out triangle interlocking. In addition the known knitting needle with spring lever, transmission heel is arranged on the end, and wherein, transmission heel is maintained on the position sinking to needle-bar by the spring force of shank. But these knitting needles are highly unstable, thus knitting needle can buckling when transmission heel is loaded by trigonometric curve.

In all solutions, reliable except insert promotes and except decline, it is also important that insert when its transmission heel with trigonometric curve interlocking namely they be in its inactive position or transmission heel promote, do not implement needle track longitudinally upper undesirable motion, particularly pulling motion.

Summary of the invention

It is an object of the invention to, it is provided that a kind of knitting machine, wherein when the transmission of insert is called in person and dropped in needle-bar, reliably stop or at least can limit insert and move in a longitudinal direction thereof.

This purpose is achieved by a kind of knitting machine with at least one needle-bar, insert particularly knitting needle can be carry with vertically moving in its needle track, wherein, insert has when insert is not chosen not from the transmission heel that needle-bar end face is protruding, it is characterized in that, constituting at least one abutment face on insert, this abutment face abuts on the lock face of at least one portrait orientation extending substantially transversely to insert when the transmission of insert is called in person and sunk in needle-bar.

The knitting machine constituted according to the present invention at least limits the vertically moving property of insert that is that do not choose or that be in the process of choosing, or also gets rid of this vertically moving property completely. If insert is knitting needle, then the power that these knitting needles are acted on needle motion direction by yarn thus can be avoided undesirably to be drawn forward, although described knitting needle is not chosen. Therefore the knitting needle with opposite can be avoided to conflict and avoid the coil to being on pinhock to have a negative impact.

If knitting machine is so constituted in addition, abutment face is made only just no longer to abut on lock face when transmission heel promotes completely from needle-bar, then insert vertically moving during choosing process can also be got rid of. This point is particularly significant in this case, and namely second insert that is hoisted through of transmission heel carries out, and this second insert is pulled to below its transmission heel in the longitudinal direction of the first insert. In the longitudinal direction of the insert to choose, the force component of this insert to choose is acted on it is hereby achieved that compensate by choosing the forward travel of insert. In this regard, first these one of abutment faces or abutment face of insert without abutting in all the time on unique lock face, but such as can also abut on the first lock face and then abut on the second lock face again during choosing process.

These one of lock faces or lock face such as can be constituted as the step at the bottom of the pin of needle-bar. When transmission heel is sunk, at least one abutment face of insert then abuts on this step, until transmission heel is continued to lift up by corresponding amplitude.

At least one lock face described such as can also be formed by the silk thread transverse to insert genesis analysis certainly. Silk thread or laterally led the lath of whole needle-bar and provide for simple in construction each needle track and inexpensive the probability manufacturing lock face.

Lock face can certainly be at least partially disposed on triangle (Schlossteil). In this case, the abutment face of insert is preferably in the transmission heel of insert.

When having the silk thread for forming lock face, the abutment face of insert preferably so has the distribution taken the shape of the letter U in cross section, thus silk thread may be inserted between the arm of abutment face. In this manner it can be achieved the locking that insert is along two moving directions of needle track. As additionally or alternatively, it is possible to arrange the abutment face forming the plane transverse to insert portrait orientation.

Abutment face can be arranged on the optional position of insert in this regard in principle, it is desirable that be arranged in the region of transmission heel. This point is particularly suitable for the situation that transmission heel is arranged on insert rear end. If heel sink in needle-bar, then abutment face also sink to needle-bar and can with there set by lock face combined effect.

The coating reducing abrasion preferably can be made up or have to lock face and/or abutment face or through Overheating Treatment of high-abrasive material. Except there is corresponding coating, it is also possible to consider that these faces are by independent parts armouring. Abrasion can also be reduced by the design on abutment face and lock face geometric modeling. These faces such as can be limited by rounded edge and/or itself arches upward.

In the one of knitting machine preferably comprises, transmission heel can promote against the spring force acting on it. It means that transmission heel insert auto-returned when choosing end its sink in the original position of needle-bar.Thus indulge to look up at needle track and can produce narrow needle-bar, because only needing to be arranged to promote transmission heel such as promote the driving member of pusher jack form. Triangle can relatively easy be constituted in this case. Pressure triangulation techniques (Dr ü ckerschlosstechnik) can be cancelled.

Can realizing similar advantage, insert is rotatable to be arranged in needle track and transmission heel can be promoted by the gyration of insert. Be here inserted into part it is also possible that constitute, as long as thus transmission heel insert do not pass through choose part load just automatically occupy its original position sinking in needle-bar.

For realizing particularly simple three-legged structure, having the advantage that in addition, insert has only one transmission heel. Then also only must have, for this transmission heel, corresponding trigonometric curve of calling in person with pin in knitting system.

Knitting needle both can also partially constitute integratedly.

Detailed description of the invention

Fig. 1 a to c illustrates the profile of the needle track 10 of the first needle-bar 100, and this needle track is inserted into knitting needle 1, and its unique transmission heel 13 is arranged on the arm 12 of soft bending of shank 11. Transmission heel 13 is on the rear end of arm 12 thus.

Fig. 1 a illustrates knitting needle 1 and does not choose the original position promoting pusher jack 2 in situation at knitting needle 1. Transmission heel 3 is not protruding from the cover rail 200 of needle-bar, and this cover rail prevents knitting needle 1 from coming off from needle track 10. Promote pusher jack 2 to be consolidated also by corresponding rail 210. Promoting pusher jack and have heel 22, this heel can be rabbeted with unshowned triangle (Schlossteil) here, and thus promoting pusher jack 2 can vertically move. In fig 1 a, promote pusher jack 2 to be in inactive position. The transmission heel 13 of knitting needle 1 is almost sunk in needle-bar 100 completely. Transmission heel 13 has abutment face 14 at it near the side of shank 11, and this abutment face abuts on the lock face 101 of needle-bar 100. Promoting pusher jack 2 and have inclined-plane 21 on the end of knitting needle 1 at it, this inclined-plane can be reclined with the inclined-plane 15 in the transmission heel 13 of knitting needle 1 by the pusher jack 2 movement on direction, card wire gap 300.

If promoting pusher jack 2 to move in the direction of arrow 30 as shown in Figure 1 b now, then the inclined-plane 15 of knitting needle 1 is upward sliding on the inclined-plane 21 promoting pusher jack 2, thus transmission heel 13 promotes in the direction of arrow 40. On the centre position shown in Fig. 1 b, the transmission heel 13 of knitting needle 1 continues contacting of the maintenance lock face 101 with needle-bar in this regard, thus knitting needle 1 can not be driven equally in the direction of arrow 30.

Fig. 1 c illustrates that lifting pusher jack 2 is on the position of its foremost.In this position, the tip on inclined-plane 21 is in the groove 102 of abutment face 101 needle-bar 100 below. Promoting at the bottom of the pin that pusher jack 2 is formed now for knitting needle 1, its transmission heel 13 is fully elevated. This transmission heel is caught by the triangle not being shown specifically here now and so that knitting needle 1 is sent.

Fig. 2 a to c illustrates the profile of the second needle-bar 100', has been also inserted into the knitting needle 1 shown in Fig. 1 a to c and promotes pusher jack 2 in its needle track 10'. But lock face 120 is formed here by the silk thread 120 laterally across needle track 10' tensioning, as long as transmission heel 13 is not thus lifted in the position shown in Fig. 2 c completely, the abutment face 14' of knitting needle 1 is just close to silk thread.

As Fig. 3 a to c illustrates the profile corresponding with Fig. 2 a to c of needle-bar 100', but wherein, the knitting needle 1' that in needle track 10', insertion now is constituted as an alternative, this knitting needle has, on 13' is called in person in its transmission, the abutment face 16 taken the shape of the letter U in cross section, as long as thus transmission heel 13' sinks to (Fig. 3 a) completely or is maintained on the centre position shown in Fig. 3 b, between the silk thread 120 arm ready for insertion into abutment face 16. Only when the heel 13' of transmission shown in Fig. 3 c promotes completely, silk thread 120 is just completely in outside the arm of abutment face 16, thus transmission heel 13 can exceed silk thread 120 and slide, say, that knitting needle 1' can implement to discharge and pullback motion.

Fig. 4 a to 4e illustrates that the needle-bar 100 of Fig. 1 a to c together with the knitting needle 1 of Fig. 1 a to c and promotes pusher jack 2 again. But being here provided with the set square 140 with triangle 130 above needle-bar 100, this set square is restriction knitting needle 1 stroke in the vertical from the ride outs that transmission heel 13 is determined on needle-bar end face.

Fig. 4 a illustrates the lifting pusher jack 2 and knitting needle 1 that are in inactive position. Transmission heel 13 is sunk in needle-bar 100 completely. In fig. 4b, transmission heel 13 rises in centre position. Its abutment face 14 also abuts on the lock face 101 of needle-bar in this position. Triangle 130 is additionally formed the other abutment face for transmission heel 13, and therefore its front end face is similarly formed abutment face. In Fig. 4 c, the transmission heel 13 of knitting needle 1 promotes completely. Lock face 102 is no longer valid. But triangle 130 still continues and transmission heel 13 maintenance interlocking as lock face. Only by being risen to by triangle 130 in the plane of set square 140 as shown in figure 4d, whole lock faces 101 and 130 just depart from and the Qian He of knitting needle 1, thus this knitting needle from now in the vertical can freely-movable. In figure 4e, as long as having already been through triangle 150, then the release just carried out for 13 of calling in person for transmission.

Fig. 5 a to c illustrates the sectional view corresponding with Fig. 1 a to c of needle-bar 100, wherein, employs knitting needle 1 " of the 3rd composition scheme except promoting pusher jack 2. This knitting needle 1'' is distinctive in that with knitting needle 1 and 1', and transmission heel 13 " is here not arranged on the arm of soft bending, and is provided on the arm 17 of rigidity. When lifting pusher jack 2 advances in the direction of arrow 30, therefore not only promote transmission heel 13 ", and whole knitting needle 1 " is tumbled, as shown in Fig. 5 b and c. But the abutment face 14 on knitting needle 1 " locking in discharge direction calls in person 13 by transmission in the way of identical with the knitting needle 1 in Fig. 1 a to c " " and the lock face 101' on needle-bar 100 carries out.

Fig. 6 a to d illustrates the cross-sectional view of another needle-bar 100'', wherein, illustrates the knitting needle 1' of the 4th composition scheme except promoting pusher jack 2 ".Having gap 18 on the bottom surface of knitting needle 1 " ' call in person 13 in transmission " ', silk thread 120' calls in person when 13''' sinks in its inactive position in transmission and can enter in this gap, as shown in Figure 6 a. The width in gap 18 diameter more than silk thread 120' in this regard. Knitting needle thus can be made to deduct execution lengthwise movement in the scope of silk thread 120' diameter at the width in gap 18 in the inactive position of its sinking, say, that knitting needle 1' " has certain space in the vertical in its inactive position. Fig. 6 a and 6b illustrates the terminal location of moving movement under the knitting needle 1' unactivated state " called in person 13' " in transmission. In Fig. 6 a, silk thread 120' abuts on left backstop 18', and it then abuts in right backstop 18 in figure 6b " on.

Fig. 6 c illustrates how by promoting pusher jack 2 in knitting needle 1' " the movable lifting transmission heel 13 on direction " '. In this regard, the backstop 18' in gap 18 and silk thread 120' reclines, and thus knitting needle 1' " is suppressed in its ahead running. Move forward if promoting pusher jack 2, then transmission heel 13 " ' rise in its activation position, this point illustrates in fig. 6d. Knitting needle 1' " can be caught by unshowned triangle here and pass through it on this position and carry out discharging and pullback motion.
