Description
Technical field
The present invention relates to a kind of sley bar needle device (Legenadelanordnung); Be used for a kind of jacquard guide bar; Be furnished with a carriage and a plurality of sley bar pin unit that can individually from carriage, take out; In this, each sley bar pin unit has at least one displacement transmission mechanism and a head, and this carriage all has an accommodation section for each sley bar pin unit.
Background technology
A kind of jacquard guide bar is used on the warp knitting machine, so that can improve the jacquard weave possibility on this machine.The sley bar pin that is positioned on the jacquard guide bar all can individually trigger, thereby they can be shifted transmission mechanism and move along direction of displacement through it.The sley bar pin is with respect to the motion of the sley bar motion overlaid with comb joint itself, thus aspect guide the bigger possibility of acquisition.
In many cases, the sley bar pin is to be combined into portion's section or module in groups, according to this, then these sections is fixed on the sley bar.This jacquard guide bar for example disclosed in DE 196 13 385 C2.In this, on maintaining body, these maintaining bodies play a part the single triggering of sley bar pin the sley bar pin, and are fixed on portion's section by solid.On these sections, also disposed the electric control element, so as to the motion of control sley bar pin.
When adopting this sley bar needle device, if defective, the defective that for example in defective decorative pattern is shaped, is shown then must be removed sley bar needle device integral body, and replace with a new sley bar needle device.But in fact defective sley bar needle device cannot overhaul, because the sley bar pin all links to each other with control element with its displacement transmission mechanism regularly.Even for example ought have only a single displacement transmission mechanism cranky, can not re-use remaining sley bar pin and move can transmission mechanism.When demolition, also just have to the displacement transmission mechanism is damaged.
In order to address the above problem, therefore such a kind of sley bar needle device that civilian head addresses has been proposed in CN 2,009 1,018 1768.In this, each sley bar pin all is furnished with a needle holder.This needle holder has two pins on an end of its back of the body back of the body sley bar pin.These two pins stretch out through needle holder.Like this, an end of pin inserts a carriage.On the other end of pin, be nested with a holding plate, thereby can needle holder have been remained on its position.These pins are facilitated a spacing simultaneously between carrier frame plate and holding plate plate.
When adopting this sley bar needle device, no doubt can replace single sley bar pin, but its installation is quite time-consuming bothersome.Must very accurately locate by pin, could holding plate be placed.Even have only a pin or a single sley bar needle holder slightly crooked, this pin can not be aimed at and be the aperture of its configuration on the holding plate, thereby holding plate is just laid to be got at all.In addition, under this project organization situation of sley bar needle device, be difficult to reach high accuracy.
Summary of the invention
Task of the present invention is to make sley bar pin unit can on carriage, realize simple the installation.
Above-mentioned task is when the sort of sley bar needle device that adopts that civilian head addresses; Solve through following measure: head at one end go up sley bar pin unit vertically on observe; Has one first alignment tab; On its other end, have one second alignment tab, these two alignment tab are holded up face with respect to of head and on carriage, are had different distances.
Adopt above-mentioned design, just can be relatively simply not only with each sley bar pin cell location on carriage, and simultaneously it is so aimed at, make it to carry out the task of its regulation.For this reason; Head not only remains on two according on the vertical position at regular intervals each other; And these two positions also of the head on the carriage hold up face different distances arranged, thereby head also can be fixed to prevent sley bar pin unit tumbling with respect to carriage simply.When alignment tab was directed in the corresponding depression on the carriage, sley bar pin unit had in fact just installed with aiming at, need only fix just by suitable method then.These alignment tab can use relatively little quality to design, and are relatively little because act on the tilting moment of sley bar pin unit.According to this, it is relative little that the quality of sley bar needle device can keep generally, and this point can produce favourable effect to the runnability of jacquard guide bar.
Advantageously, contiguous first alignment tab of holding up face is towards a needle section; Second alignment tab away from holding up face then deviates from needle section.These two alignment tab are to be placed in diagonally on the head in this case, and cornerwise inclination is towards needle section.This point just makes it possible to sley bar needle device pin is designed with a relatively little height in the direction to needle section.Bigger height only needs in the zone away from needle section.This point helps guide easily, and these yarns should be guided through also being accommodated in the sley bar pin in the sley bar pin unit.Like this, the risk that produces fault that is in operation is very little.
Advantageously, the accommodation section has that one first section is used for first alignment tab and one second section is used for second alignment tab, and in this, second section forms a continuation of first section, and two alignment tab have identical thickness.Just can two sections of accommodation section be made completion in one procedure, for example employing dish milling cutter processing.Two sections that so also just guaranteed the accommodation section have the aligning of hoping each other.Along with the insertion of sley bar pin unit, this moment, two alignment tab also were inserted in two upper curtates of accommodation section, just can guarantee the reliable alignment of sley bar pin unit then.
Advantageously, the degree of depth that has of first section is less than the height of head.That is to say that first section can be flat relatively.Consequently: carriage also can have relatively little thickness in this zone.This also is an advantage, because just can keep the little quality of carriage like this.What prevent that sley bar pin unit from tumbling does not carry out in the scope of first section of accommodation section yet, but in the scope of second section of accommodation section, just carries out.Here, carriage can have bigger height then, but this point be not crucial, because this bigger height can be limited on the less section of carriage.
In this, advantageously, head stretches out towards carriage with a part that exceeds that exceeds the displacement transmission mechanism, and the degree of depth of first section exceeds part less than this.In this, locate the part that protruding ultra portion forms head.Therefore can settle the displacement transmission mechanism with enough distance ground, thereby make the displacement transmission mechanism not receive carriage to make the sley bar pin with hindering, or rather, carry the comb markingoff pin unit motion of sley bar pin to carriage.
In this, advantageously, the thickness that alignment tab has is less than head.So can the both sides of the alignment tab of head in first section that inserts the accommodation section be placed on the carriage, thereby obtain definite face of holding up at this.This is holded up face and also has enough size, thereby head can be erected on carriage with the accuracy of necessity.
Advantageously, head has a protrusion geometrical configuration towards syringe needle, and this geometrical configuration is meshed with the recessed geometrical configuration of a kind of side of carriage.When protrusion geometrical configuration when being meshed with the recessed geometrical configuration of side, head and thus sley bar pin unit can not take off from carriage again.On this position, sley bar pin unit just form fit remains on the carriage with connecting.
Advantageously, engagement geometrical configuration and the recessed geometrical configuration of side have suitable each other inclined-plane.When sley bar pin unit on the carriage when the direction of syringe needle moves, the head of sley bar pin unit just is pressed on the carriage.So promptly reach very accurate localization.
Advantageously, carriage has a bearing on a side that deviates from syringe needle of head, and a dismountable clamping element is positioned between this bearing and this size portion.Utilize this clamping element, this head can be clamped with respect to this bearing.Especially under the situation that combines engagement geometrical configuration and the recessed geometrical configuration of side; Just can be through the installation or the clamping of this clamping element; Guarantee that sley bar pin unit is fixed on the carriage enduringly, in this, this fixing can be through clamping element demolition or unclamp again and remove.
In this advantageously, clamping element acts on a lozenges on the head.Like this, head also can be in a side that deviates from syringe needle with certain defeating on carriage.
Advantageously, clamping element designs as eccentric pin.An eccentric pin can act on a plurality of sley bar pins unit simultaneously.This off-centre pin can unhinderedly be conducted through between the head of bearing and sley bar pin unit on one first position of rotation.When it was covered with the sley bar unit of all configurations, it rotated simply, and subsequently sley bar pin unit was clamped with respect to bearing.
Advantageously, head has a hook portion, in this hook portion, has set a control circuit version.This hook portion is guaranteed the location of control circuit version with respect to head then.In this, on head, disposed contact, spring contact preferably, these spring contacts abut on the contact-making surface of control circuit version, and between control circuit version and displacement transmission mechanism, realize a kind of connection.So can trigger the single displacement transmission mechanism of sley bar pin through the control circuit version.
