Description

Carbon fibre reinforced composite material heald framework processed stave and side stay bar installation portion structure
Technical field
The present invention relates to the structure of the heald framework that is usually used for loom, particularly carbon fibre reinforced composite material heald framework processed stave and be used for linking the side stay bar installation portion structure of carbon fibre reinforced composite material heald framework processed stave and side stay bar.
Background technology
The heald framework is that supporting is used for heald (harness cord) by warp thread in loom, is for when weaving, make a pair of heald framework alternately move up and down to make Warp opening, throws weft yarn into this opening.
Usually, heald framework 1 as Fig. 1 represents the one example, has the upper and lower frames framework stave that extends at length direction (arrow A direction), that is the side stay bar 3 that, has two chassis body 2 and binding two chassis body 2 at the length direction both ends that are configured in two chassis body 2.In addition with in opposite directions one distolateral mutually of the short side direction (arrow B direction) of the length direction quadrature of chassis body 2, formed the support projection portion 5 that the hook that heald 4 supported along the length direction of chassis body 2 is used.
In addition, chassis body 2 and side stay bar 3 usually, are connected with demountable structure by linking part 6.In addition, be used for preventing that the guide plate 7 of heald framework 1 interference each other, the coupling 8 that transmits the position of the power that moves up and down to heald framework 1 are installed in heald framework 1.
Chassis body 2 nearly all is aluminum at present.Under the situation of aluminium sash main body 2, as shown in Figure 2, be hollow-core construction, but in order to guarantee the intensity of hollow parts, become to comprise the structure of many cross ribs 21.
But, if improve the speed of knitting of loom, then because the intensity, particularly fatigue strength of aluminium are not high, under As-Is, use less than half a year continuously, just have to replace.
In recent years, for corresponding with the high speed of loom, various light fiber reinforced composite materials (FRP) heald framework processed has been proposed.
For example, in patent documentation 1, the associated methods of FRP framework stave processed and side stay bar is disclosed, in patent documentation 2, while proposed to guarantee the structure of part exchangings such as the rigidity of FRP heald framework processed, intensity are damaged easily, worn out middle suspension hook, bar support portion.
At present, the high speed of loom, wide cutization become the trend in the world gradually, and wide cutization has proceeded to fabric width namely surpasses the fabric of 3500mm with the length direction length of the direction of paper quadrature in Fig. 2 making as loom.The chassis body of this type is aluminum, increases but be accompanied by the load that wide cutization is added on the chassis body, can not fully follow intensity, rigidity to it, if raising speed then cause the damage of chassis body.Therefore, the advantage of weaving, do not enjoy wide cutization that can not improve speed is actual conditions.
On the other hand, proposed to have used as reinforcing fiber the fiber reinforced composite material of carbon fibre, namely, used the scheme of the chassis body of CFRP, its part is used, but intensity, rigidity because of product are also not enough, so actual conditions are the fabrics that only are applicable to about fabric width 1500mm.Even its reason is because become lightweight, because the deficiency of intensity, rigidity, so can not improve the speed of loom.
That is to say, because be the CFRP system, simultaneously intensity, so rigidity is not enough can not be corresponding with wide cutization, as one of its reason, be because CFRP heald frame structure processed becomes hollow-core construction or only put into the structure of expanded material in inside, so can not guarantee full intensity, particularly be difficult to guarantee fatigue strength.Therefore, under present situation, can only in the narrow loom of fabric width, use, and can not realize enough high speeds.
If in order to ensure intensity, the rigidity of CFRP heald framework processed, make solid construction, its corresponding effect then appears, become heavy but on weight, compare with aluminum, and cost uprises also, the advantage of use does not almost have.
Therefore, present inventors have made maximum intensity, the rigidity of performance in confined structure, and the strong structure of fatigue strength in light weight, thus, so far fail the productive fiber reinforced composite material heald framework processed of loom of the wide cutization that realizes in order to provide can the earth to improve, in patent documentation 3, fiber reinforced composite material heald framework processed has been proposed.
Fig. 3 represents the summary structure of the fiber reinforced composite material heald framework processed of patent documentation 3 records.In this example, fiber reinforced composite material heald framework processed has the chassis body 2 of the substantially planar that extends at length direction (length L) of elongated shape, the support projection 5 that is connected integratedly along its length direction with lower end in this chassis body 2.Chassis body 2 has celluar tissue structure 4 at internal layer, on internal layer two-sided, with the state configuration of the celluar tissue structure 4 of clamping internal layer as continuous fiber reinforced composite 11(11a, the 11b of superficial layer).And then part or all of end face around the celluar tissue structure 4 of internal layer packed in the celluar tissue structure 4 by staple fibre being strengthened composite wood, resin or expanded material in the scope of width 3mm～30mm, forms enhancing portion 9.
But, in the heald framework that is proposed by patent documentation 3, when linking with the side stay bar, had to adopt mode in the past, for example, the such mode shown in the patent documentation 1.In such mode, in order to link, need to insert accessory, therefore, need numerous and diverse operation such as bonding of removal, the accessory of celluar tissue, become the reason that cost rises.
In addition, linking method in the past, because the mode that is to use the accessory of multiple class to link weighs so the weight at this position becomes, light-weighted advantage reduces half.
Therefore, present inventors have proposed the heald framework processed of the fiber reinforced composite material shown in the patent documentation 4.The overall structure of Fig. 4 representational framework main body 2.In this example, chassis body 2 is made into the structure same with the chassis body 2 of above-mentioned patent documentation 3 shown in Figure 3, in internal layer, has celluar tissue structure 9, continuous fiber reinforced composite 11(11a, 11b in superficial layer, have been disposed), and the celluar tissue structure 9 of internal layer around part or all of end face, pack in the celluar tissue structure 4 by in the scope of width 3mm～30mm, staple fibre being strengthened composite wood, resin or expanded material, form enhancing portion 10.Just in this example, as shown in Figure 4, chassis body 2 has been made into the structure that will fix in the side stay bar that both sides form is installed the groove 3A of jut 60 inserting side stays 3.

Therefore, it is optimal making conduct bear these loads at the upper plate 10a of the cross rib of the carbon fibre reinforced composite material of the length direction extension of the topmost of heald framework stave 2.
Therefore, in the present invention, will for to the metal bar 20 processed of side stay bar 3 direct transfer charges by the upper plate 10a that is installed in as cross rib such as bonding integratedly, become the structure of the cross section rigidity that can bring into play heald framework stave 2 to greatest extent.
(3) then, as to the desired function of heald framework, the precision of fixation side stay 3 is arranged.
Side stay bar 3 has the effect of assembling each heald framework stave 2 up and down in a certain interval and keeping its precision.If do not do like that, the change width at the position of heald then is installed, produce and maybe heald can not be installed, or problem such as lost by the woven heald midway of loom.
What determine this precision is exactly the metal bar 20 processed that is bonded in the top of heald framework stave 2.
With the precision that determines side stay bar 3 install and in operation this precision constant be necessary.If the face of installation side stay 3 is made the carbon fibre reinforced composite material, then because be the resin face, so owing to wearing and tearing, scuffing etc., change during long-term use produces undesirable condition.Therefore, the face of fixation side stay 3 must be the metal covering that hard difficulty is worn and torn.
Accuracy guarantee when metal bar 20 processed is installed, be when bonding, carry out with giving one's full attention to bonding, even or make that for example precision is bad, but by processing the structure that can tackle afterwards.
By the way, the precision of installation side stay 3, the precision at the interval of the installation heald during as installation side stay 3 is ± 0.1mm.
(4) then, be intensity to heald framework 1 desired function, to destroy not be important for the fastening force that is produced by the set bolt 38 by installation side stay 3, the load from heald, woven silk that applies at work.
These both sides' load all is applied to fixing with on the metal bar 20 processed, and this is fixing to be adhered on cross rib (upper plate) 10a of the carbon fibre reinforced composite material system of the length direction extension on the top of the heald framework stave 2 of installation side stay 3 with metal bar 20 processed.
At first, when using set bolt 38 installation side stays 3, the fixed component (insertion section 31) of inserting side stay 3 between second metal bar 35 processed, 40,42 of first metal on top bar 20 processed and bottom, and it is fastening by bolt 38.At this moment, the counter-force of bolt 38 is born by carbon fibre reinforced composite material cross rib processed (upper plate) 10a on heald framework stave top top (bolt head following).So, at this carbon fibre reinforced composite material cross rib processed (upper plate) above the 10a and between bonding first metal of going up the in its lower section bar 20 processed, apply gradually with by the identical compression stress of the fastening power of bolt 38.
Because this compression stress is born by solid carbon fibre reinforced composite material cross rib processed (upper plate) 10a and first metal bar 20 processed, so become the structure that can not destroy.On the other hand, if by the carbon fibre reinforced composite material of side side plate 11(11a processed, 11b) bear this compression stress, then carbon fibre reinforced composite material distortion or destroy and can not bear sufficient power.
Much less, for safety, the metal packing ring of packing under the head of set bolt 38, carbon fibre reinforced composite material (upper plate) 10a below the protection also is useful.
Then, the power when being weaved by loom, it makes heald framework power up and down, first metal bar 20 processed above side stay bar fixed component (insertion section 31) progresses into.This power is the power that promotes the heald that is installed on the heald framework stave 2, the tension force of woven silk etc., and is so not big.
This power enters laterally extending carbon fibre reinforced composite material cross rib processed (upper plate) 10a on heald framework stave 2, by being bonded in carbon fibre reinforced composite material side plate 11(11a processed, the 11b of the bar side on this cross rib (upper plate) 10a), power passes to bar integral body gradually.
With respect to this power, laterally extending carbon fibre reinforced composite material cross rib processed (upper plate) 10a on heald framework stave and carbon fibre reinforced composite material side plate 11(11a processed, the 11b of bar side) bonding force be necessary.Therefore, in order to ensure bond area, laterally extending carbon fibre reinforced composite material cross rib processed (upper plate) 11a on heald framework stave, similarly, thickness H1, the H2 of cross rib (lower plate) 11b need more than the 5mm.
As shown in Figure 8, by rivet 22 fixing top first metal bars 20 processed, be some things in the operation, be purpose to prevent the bonding Security Countermeasures of peeling off.
(5) then, to the function that heald framework 1 requires, be to guarantee woven speed.
Therefore, guarantee that much less the above cross section rigidity of cross section rigidity of the aluminum heald framework of present situation is, 1 intrinsic frequency of heald framework stave 2 also requires more than the aluminum of present situation.
Make at the carbon fibre of the PAN class carbon fibre (tensile elasticity rate is more than the 235GPa) of the extensive use of cheapness on the use cost under the situation of heald framework stave 2, know: if the top and bottom of the 2A of hollow-core construction portion that makes at heald framework stave 2 have disposed cross rib 10(10a, the 10b more than the width 5mm) structure, then the cross section rigidity of above-below direction can be guaranteed more than aluminum.
With respect to 1 intrinsic frequency, use tensile elasticity rate and the density of material to become main points.
At this, because the tensile elasticity rate of aluminium is 70GPa, density is 2.7g/cm 3, using the average tensile elasticity rate of CFRP is 107GPa, density is 1.6g/cm 3If length is identical, then the root (extraction of square root) of 1 intrinsic frequency and tensile elasticity rate is in direct ratio, and is inversely proportional with the root (extraction of square root) of density, so 1 intrinsic frequency of heald framework stave 2 of the present invention becomes about 1.6 times of aluminum, 1 intrinsic frequency is no problem as can be known.
(6) the reel frame is also required quietness certainly.Particularly be accompanied by environmental problem recently, particularly in Europe the requirement of the high heald framework of quietness uprised.
Relative therewith, CFRP heald framework processed stave because be compound with resin, so originally resonance qualitly is few at framework, becomes the high product of quietness on one's body.
And then in order to improve its effect, at the hollow part of CFRP heald framework processed stave, except the end of installation side stay, the expanded material of the carbamate of packing into, the celluar tissue of paper etc. also can further improve effect.
