For this purpose, the stops are transversely staggered arranged in the movement direction outside the movement space of the guide needles (4) and each guide needle (4) is respectively connected with a projection (13) projecting transversely in the movement direction and in an intermediate space between every two adjacent guide needles matched with the stops.
Description
Technical field
The present invention relates to the particularly sley point device of Raschel looms of a kind of knitting machine, there is maintenance equipment and be arranged on the multiple sley points on this maintenance equipment, wherein each sley point has bending variation device (Biegewandleranordnung), at least a portion sley point can be shifted along moving direction by described bending variation device, each sley point is equipped with two backstops, and these backstops limit described part sley point and are shifted along moving direction.
Background technology
This sley point device is for example known by DE4126899C1.Maintenance equipment with sley point provided thereon is fixed on sley bar.Utilize bending variation device can make the syringe needle of each sley point with respect to guide bar shogging, thereby utilize this sley point device can realize jacquard control, the guide eye that connects yarn is just arranged on described syringe needle.The moving direction of the displaceable part of sley point is parallel to the sideslip direction (Versatzrichtung) of sley bar.The moving direction of the described part of sley point can or contrary identical with sideslip direction.
In order to ensure accurately locating sley point, exactly, be its syringe needle of location, under known case, make sley point move between two backstop.These backstops, through suitably locating, make sley point can between two adjacent splits that form by knitting needle (Gassen), swing (durchschwingen).These backstops are " comb " shape at this, and closer the sley point head place that is positioned at.This makes number is that the sley point quantity of per unit length is very limited.Number is higher, and the space that can use to backstop is just less.Therefore these limiting structures must be obtained very narrow.In the time that number is E32 (per inch has 32 sley points), be less than 0.4mm for the space of broach, now use the sley point that 0.4mm is thick.This backstop is therefore mechanically very insecure.Particularly in theory only have a half width can in the fringe region of tooth for this kind of situation.In practice, this problem is comb to be started with full tooth, and stop with gap at current settling mode.But this can make a rear sley point device all need all the time an adjacent sections.This can increase again the quality that needs to be moved by sley bar.If it is very narrow that tooth is backstop, will there is at work the impaired danger that causes interference.
Summary of the invention
The object of the invention is to, the work of knitting machine is interfered, and there is very little risk, and number is higher simultaneously.
In the sley point device of type described in the beginning part, the implementation of described object is, make backstop stagger and be arranged in outside the space of sley point transverse to moving direction, and each sley point is connected with projection, described projection is transverse to moving direction projection, and extend in two intermediate spaces of attaching troops to a unit between the backstop of sley point.
Adopt this design can in the time of structure backstop, there is the larger free degree.These backstops are mechanically constructed more firmly.They particularly also away from closely adjacent region of sley point syringe needle.So just can avoid producing and disturbing in yarn distributes.Operational installing space can better be utilized.In the time using multiple sley bar, these pins can be described as and are each other fan layout, make thus their syringe needle substantially be in a straight line.Therefore near syringe needle, only have the smaller space can be for arranging backstop very nearby.From syringe needle more away from, operational installing space is just more.
Preferred each backstop is maintained on backstop frame at least two different height.For example can specify, described intermediate space is configured to the groove in backstop frame, wherein this groove have along its longitudinal extension (
) change the degree of depth.Alternatively, groove also can have rectangular cross section.The direction of extension of longitudinal extension of groove is arranged essentially parallel to longitudinal extension of sley point.If the vicissitudinous degree of depth of groove tool, the end that these backstops deviate from sley point at it is not only fixed on backstop frame along straight line, and is fixed at various height.In the time being rectangle, these backstops its bottom be fixed, and its bottom above end be fixed.These backstops are mechanically more firm thus.They overcome, and pulling force is relative with pressure to be supported.
Preferred described sley point device has contact pin, these limiting structures are in described contact pin, these contact pin make adjacent intermediate space separately, and wherein these contact pin have the surface towards sley point, this surface particularly with the surface in alignment towards sley point (fluchten) of backstop frame.Do not see so bypass groove, backstop frame has even curface, and does not have noisy projection.In fact the risk of disturbing yarn to distribute due to this projection is completely eliminated thus.These contact pin thereby (taking longitudinal extension of groove as benchmark) is fixed also at two ends, make they mechanically than the independently dental transition of comb (Kamm) for firmly.These contact pin therefore can be thinner.
Here the contact pin that preferably, is positioned at sley point device edge along the width of moving direction be not arranged on the contact pin of this edge width 50%.So just can use sley point device, even if there is no adjacent sley point device in its end.Here the contact pin with a half width is used as to backstop, because it mechanically can be enough firm.
Preferably groove has bending bottom.Bottom for example can be circular arc.So can adopt simple mode for example with quarter milling cutter make groove.
Preferably make backstop frame and keep equipment connection, or constructing integratedly with maintenance equipment.So adopt simple mode to realize accurate configuration between backstop frame and maintenance equipment.
Preferred each sley point is fixed in needle-bar plate, and projection is configured on this needle-bar plate.Therefore use standard sley point or eye needle guide, and at this without taking for protruding special measure is provided.
Preferably projection is less than needle-bar plate along the width of moving direction.Therefore projection can be thinner than needle-bar plate.Also can use thus wider contact pin, then this contact pin can be designed to be corresponding firmly.
Preferred pin bed board and projection are constructed integratedly.Needle-bar plate and projection for example can adopt injection moulding process to make by plastics.Projection obtains enough intensity thus, even if it is thinner.
Also advantageously, sley point is greater than projection along the width of moving direction.Can use in this case more firmly sley point, and can not make backstop become weak.
Preferred pin bed board and sley point have locking mechanism (Rastgeometrie), and projection is just arranged in the region of this locking mechanism.For example sley point can be inserted in the groove of needle-bar plate, this groove therein side has kayser projection, and this kayser projection snaps onto in the groove on sley point.So sley point is fixed by certain stress, needle-bar plate is applied to this stress on sley point.Projection can be reinforced needle-bar plate in the region of locking mechanism, thereby can adopt simple mode to increase confining force at this.
Along the longitudinal 2 observation of sley point, needle-bar plate preferably substantially ends at identical position with backstop frame in the syringe needle region of sley point.Needle-bar plate thereby can in fact extend to the syringe needle of sley point.So just can very reliably sley point be fixed.In fact sley point bed board ends at identical height with backstop frame, thereby if situation is really like this, produces very little ladder.The yarn risk being disturbed that distributes is corresponding less.

Fig. 4 is that the A-A of Fig. 3 is to cutaway view.
Detailed description of the invention
For the knitting machine that is shown specifically particularly the sley point device 1 of Raschel looms be fixed on the sley bar 2 shown in only local.Sley point device 1 has maintenance equipment 3, is provided with multiple sley points 4 on this maintenance equipment.Each sley point 4 has the syringe needle 5 with guide eye 6, and yarn can pass this guide eye at work later, and this yarn is preferred for making the knitwear that must make to produce decorative pattern.Each sley point 4 is fixed in needle-bar plate 7.Between needle-bar plate 7 and maintenance equipment 3, be provided with an only schematically illustrated bending variation device 8 for each sley point 4, utilize this bending variation device at least can make the syringe needle 5 of sley point 4 be shifted along moving direction.Moving direction is parallel to the extending longitudinally of sley bar 2.As bending variation device 8, can use the bending variation device of for example piezoelectricity, so be provided with one or more this flexural piezoelectric variation devices on each sley point 4.
Each sley point 4 can be controlled separately.The syringe needle 5 that so just can make each sley point 4 in the time that sley bar 2 moves along sideslip direction or with sideslip direction contrary move.The motion of the syringe needle 5 of sley point 4 thereby overlapping with the motion of sley bar 2, this is for example originally known.
In order to ensure accurately locating syringe needle and sley point 4, each sley point 4 needs two backstops, and these backstops are the two ends of tracks restriction sley point 4 moving along moving direction.
These backstops under present case, be configured in backstop frame (
) on 9.Backstop frame 9 staggers and arranges with the space of sley point 4 or its syringe needle 5 transverse to the moving direction (this is perpendicular to the direction of the drawing of Fig. 4) of sley point 4.Backstop frame 9 has a groove 10 with curved bottom 11 for each sley point 4.This bottom is for example circular arc, thus can use carve milling cutter (
) set out groove 10.
So adjacent groove 10 is separated from each other by contact pin (Steg) 12.So longitudinal (this is the direction extending longitudinally that is arranged essentially parallel to sley point 4) at groove 10 above fixes the two ends of these contact pin 12.These contact pin 12 thereby be not only connected with backstop frame 9 with its bottom surface along straight line be for example this kind of situation for dentalation, and they have higher mechanical strength with respect to simple tooth.These contact pin 12 thereby can be configured to relatively narrow.
Needle-bar plate 7 has the projection 13 extending in groove 10.Projection 13 preferably and needle-bar plate 7 construct integratedly.But it has the width less than needle-bar plate 7.The width of projection 13 even can be less than (moving direction along sley point 4 is observed) thickness of sley point 4 on moving direction.
Each sley point 4 is inserted in the shrinkage pool 16 on needle-bar plate 7.In shrinkage pool 16, be provided with kayser projection 14, this kayser projection 14 extend in the groove 15 on the shank of sley point 4.Sley point 4 thereby be fixed in needle-bar plate 7 by the kayser bindiny mechanism being formed by kayser projection 14 and groove 15.In this case, needle-bar plate 7 utilizes two sections 17,18 to apply elastic force to sley point 4.
If projection 13 is arranged on to a certain region, in this region, be also provided with kayser projection 14, be correspondingly also provided with the groove 15 of sley point 4, section 18 is reinforced, and the bed knife being applied on sley point 4 is improved.
Backstop frame 9 is relatively closely arranged on needle-bar plate 7.Spacing between needle-bar plate 7 and backstop frame 9 can be less than the thickness (being distance from left to right in Fig. 4) of sley point 4.Correspondingly, projection 13 can keep relatively short, is applied to it thereby do not have larger lever force here.
The backstop frame 9 with the backstop in contact pin of being configured in 12 is arranged in the space of sley point 4 and needle-bar plate 7 thereof.Thereby this backstop frame will not disturb this motion.
In the roughly termination part of backstop frame 9, needle-bar plate 7 also stops, and that is to say, surrounding's maintenance of the syringe needle 5 of sley point 4 does not have noisy parts.So just make in yarn distributes, to produce the risk of disturbing and keep less.
As described in, limiting structure is in contact pin 12.Here in its both sides, the moving direction along sley point 4 forms two backstops in each contact pin 12.But along moving direction be positioned at the contact pin 12 of sley point device end ' except.At this, a backstop of each contact pin 12 ' only have.So this contact pin 12 ' width only have the half of other contact pin 12.This can be achieved owing to being configured with backstop in contact pin, as described in, this is because the mechanical strength of these contact pin is greater than simple tooth.
Adopt described design correspondingly to arrange to there is high-count the sley point 4 of (Feinheit), and can not exist for the impaired danger at work of the backstop of sley point 4.
