Description

Carbon fibre reinforced composite material heald frame stave and side stay bar installation portion structure
Technical field
The present invention, relates to the structure being usually used for the heald frame of loom, particularly to carbon fibre reinforced composite material heald frame stave and for linking the side stay bar installation portion structure of carbon fibre reinforced composite material heald frame stave and side stay bar.
Background technology
Heald frame is to support for by the heald (harness cord) of warp thread in loom, is for when weaving, making a pair heald frame alternately move up and down and make Warp opening, throw weft yarn into this opening.
Usually, heald frame 1, represents such as Fig. 1 one example, has longitudinally the upper and lower frames framework stave that (arrow A direction) extends, that is, the side stay bar 3 linking two chassis body 2 at the length direction both ends that there are two chassis body 2 and be arranged in two chassis body 2.Additionally in the end side opposite each other of the short side direction (arrow B direction) orthogonal with the length direction of chassis body 2, form the support projection portion 5 to the hook that heald 4 supports of the length direction along chassis body 2.
It addition, chassis body 2 and side stay bar 3, usually, linking part 6 connect with demountable structure.In addition, for preventing the guide plate 7 of heald frame 1 interference each other, being installed in heald frame 1 to the coupling 8 at the position of the power of heald frame 1 transmission up and down motion.
Chassis body 2, is nearly all aluminum at present.When aluminium sash main body 2, as in figure 2 it is shown, be hollow-core construction, but in order to ensure the intensity of hollow parts, become the structure including many cross ribs 21.
But, if improve loom knit speed, then due to the intensity of aluminum, particularly fatigue strength is not high, under As-Is, uses less than half a year continuously, would have to be replaced.
In recent years, in order to the high speed with loom is corresponding, it is proposed that various light fiber reinforced composite material (FRP) heald frame processed.
Such as, in patent documentation 1, disclose the associated methods of FRP framework stave and side stay bar, in patent documentation 2, it is proposed that guarantee the rigidity of FRP heald frame, intensity easily carry out damaging, the structure of worn out middle suspension hook, the part exchanging such as bar support portion.
At present, the high speed of loom, wide cutization have been increasingly becoming the trend in the world, wide cut, have proceeded to the making of the length direction length in namely orthogonal with the paper in fig. 2 direction of the fabric width fabric more than 3500mm as loom.The chassis body of this type, is aluminum, but is added in the load in chassis body along with wide cut and increases, it is impossible to fully it being followed intensity, rigidity, if improving speed, causing the damage of chassis body.It is thus impossible to the weaving carrying out improving speed, the advantage of not enjoying wide cut are practical situations.
On the other hand, it is proposed that employ the fiber reinforced composite material of carbon fibre as reinforcing fiber, namely, employ the scheme of the chassis body of CFRP, one part has been used, but because the intensity of product, rigidity are also not enough, so practical situation is to be only applicable to the fabric about 1500mm width.Its reason is because namely becoming lightweight, because the deficiency of intensity, rigidity, so the speed of loom can not be improved.
That is, because being CFRP system, simultaneously intensity, rigidity is not enough so can not be corresponding with wide cutization, as one of its reason, it is because CFRP heald frame structure become hollow-core construction or be simply placed in the structure of expanded material in inside, so cannot ensure that sufficient intensity, particularly it is difficult to ensure that fatigue strength.Therefore, under present situation, can only use in the narrow loom of fabric width, and enough high speeds can not be realized.
If in order to ensure the intensity of CFRP heald frame, rigidity, making solid construction, then its corresponding effect occurs, but in weight, becomes weight compared with aluminum, and cost also uprises, the advantage of use almost without.
Therefore, the present inventors have made and have played maximum intensity, rigidity in confined structure, and the structure that lightweight fatigue strength is strong, thus, the productive fiber reinforced composite material heald frame of loom of wide cut failing so far to realize can be greatly improved in order to provide, in patent documentation 3, it is proposed that fiber reinforced composite material heald frame.
Fig. 3 represents the Sketch of the fiber reinforced composite material heald frame that patent documentation 3 records.In this example, fiber reinforced composite material heald frame, there is the chassis body 2 of the longitudinally substantially planar that (length L) extends of elongated shape, and in the support projection 5 that the lower end of this chassis body 2 connects integratedly along its length direction.Chassis body 2, has areolar tissue structure 4 at internal layer, internal layer two-sided on, the state to clamp the areolar tissue structure 4 of internal layer is configured with the continuous fiber reinforced composite 11 (11a, 11b) as surface layer.And then, part or all of the surrounding end surfaces of the areolar tissue structure 4 of internal layer, loading in areolar tissue structure 4 by chopped fiber being strengthened composite wood, resin or expanded material in the scope of width 3mm～30mm, forming enhanced portion 9.
But, in the heald frame proposed by patent documentation 3, when linking with side stay bar, it has to have employed conventional mode, for instance, the such mode shown in patent documentation 1.In such mode, in order to link, it is necessary to insert accessory, accordingly, it would be desirable to numerous and diverse operation such as bonding of the removal of areolar tissue, accessory, become the reason of cost increase.
It addition, conventional linking method, because being use the accessory of multiple types to carry out the mode linked, so the weight at this position becomes weight, light-weighted advantage reduces half.
Therefore, the present inventors propose the fiber reinforced composite material heald frame shown in 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 the patent documentation 3 shown in above-mentioned Fig. 3, internal layer has areolar tissue structure 9, surface layer is configured with continuous fiber reinforced composite 11 (11a, 11b), and part or all of the surrounding end surfaces of the areolar tissue structure 9 of internal layer, loading in areolar tissue structure 4 by chopped fiber being strengthened composite wood, resin or expanded material in the scope of width 3mm～30mm, forming enhanced portion 10.Simply in this example, as shown in Figure 4, chassis body 2 has been made into structure fixing in the groove 3A that the side stay bar mounting protrusion portion 60 formed in both sides inserts side stay bar 3.

In the various embodiments described above, carbon fibre reinforced composite material heald frame stave and side stay bar installation portion structure to the present invention are illustrated in detail, then, the feature generalizations of the situation of the carbon fibre reinforced composite material heald frame stave 2 employing the present invention making said structure on the heald frame of loom is illustrated.
As it has been described above, in the heald frame of loom, it is desirable to heald frame stave to be made carbon fibre reinforced composite material goods, lightweight and high rigidization realize the high speed of loom, damping.Much less, with long sizing to realize that quality improves accordingly be necessary.Therefore,
(1) linked the heald frame 1 (with reference to Fig. 1) that upper and lower heald frame stave (chassis body) 2 is constituted by side frame 3, how to reduce the important main points that upper and lower flexure becomes in design.Therefore, it can the carbon fibre reinforced composite material considering intensively to put into high resiliency rate in the edge, above-below direction both sides of each heald frame stave 2.
Consider this problem, in the present invention, become following structure, namely, in the edge, both sides up and down of the hollow-core construction portion 2A of the heald frame stave 2 making hollow-core construction, the cross rib 10 (10a, 10b) that configuration is made by the CFRP (one direction carbon fibre reinforced composite material) of the UD shape that long fibre longitudinally pulls together making.
It is to say, the present invention becomes the structure maximally being obtained determining the cross section rigidity of the heald frame stave 2 of the above-below direction of the flexure of above-below direction by such structure with less material.
(2) on heald frame stave 2, suspending heald, woven silk in midair in lower end, load is applied to there.Next the point accepting this load becomes critically important.In order to the flexure making above-below direction is minimum, it is necessary to the cross section rigidity of heald frame stave 2 is performed to position to greatest extent, there is the point accepting this load.
Therefore, it is optimal that the upper plate 10a making the cross rib of the carbon fibre reinforced composite material extended as the length direction of the topmost at heald frame stave 2 bears these loads.
Therefore, in the present invention, using for being integrally arranged on the upper plate 10a as cross rib to the metal bar 20 of the direct transfer charge of side stay bar 3 by bonding grade, the structure of the cross section rigidity that can play heald frame stave 2 to greatest extent is become.
(3) then, as to the function required by heald frame, there is the precision of fixing side stay bar 3.
Side stay bar 3, has the effect assembling upper and lower each heald frame stave 2 in a certain interval and keep its precision.If do not done, then the change width at the position of heald being installed, producing maybe can not install heald, or the problem such as lost by loom woven midway heald.
Determine the metal bar 20 on the top being bonded in heald frame stave 2 exactly of this precision.
Precision to determine side stay bar 3 is installed and this precision is constant in operation is necessary.If carbon fibre reinforced composite material is made in the face of installation side stay 3, then because being resin face, so, due to abrasion, scuffing etc., change in the period of life-time service, produce undesirable condition.Therefore, the face of fixing side stay bar 3, it is necessary to be the metal covering of hard difficult abrasion.
Accuracy guarantee during metal bar 20 is installed, be carry out with giving one's full attention to when bonding bonding, even if or to make such as precision bad, but pass through the structure being processed afterwards tackling.
By the way, the precision of installation side stay 3, the precision at the interval installing heald during as installation side stay 3, is ± 0.1mm.
(4) then, be intensity to the function required by heald frame 1, not by the fastening force produced by the fixing bolt 38 of installation side stay 3, apply at work from heald, woven silk load destroy be important.
The load of these both sides is all applied to fixing with on metal bar 20, on cross rib (upper plate) 10a of the carbon fibre reinforced composite material of the length direction extension on the top of this fixing heald frame stave 2 being adhered to metal bar 20 at installation side stay 3.
First, when using fixing bolt 38 installation side stay 3, insert the fixing component (insertion section 31) of side stay bar 3 between the first metal bar 20 and the second metal bar 35,40,42 of bottom on top, and it is fastened by bolt 38.Now, the counter-force of bolt 38 is born by (below the bolt head) above of carbon fibre reinforced composite material cross rib (upper plate) 10a on heald frame stave top.Then, on this carbon fibre reinforced composite material cross rib (upper plate) 10a and be bonded between the first metal bar 20 gone up below, the compression stress identical with the power fastened by bolt 38 is applied gradually.
Because this compression stress is born by solid carbon fibre reinforced composite material cross rib (upper plate) 10a and the first metal bar 20, so becoming the structure that will not destroy.On the other hand, if to be born this compression stress by the carbon fibre reinforced composite material side plate 11 (11a, 11b) of side, then carbon fibre reinforced composite material deforms or destroys and can not bear sufficient power.
Much less, for safety, loading metal packing ring in the underface of the head of fixing bolt 38, it is also useful for protecting following carbon fibre reinforced composite material (upper plate) 10a.
Then, loom power when weaving, it makes the power that heald frame is upper and lower, progresses into the first metal bar 20 above from the fixing component (insertion section 31) of side stay bar.This power is an up the power of the tension force etc. of the heald being arranged on heald frame stave 2, woven silk, less greatly.
This power enters carbon fibre reinforced composite material cross rib (upper plate) 10a of the horizontal expansion on heald frame stave 2, the carbon fibre reinforced composite material side plate 11 (11a, 11b) of the stave side by being bonded on this cross rib (upper plate) 10a, power passes to stave entirety gradually.
Relative to this power, the bonding force of carbon fibre reinforced composite material cross rib (upper plate) 10a of the horizontal expansion on heald frame stave and the carbon fibre reinforced composite material side plate 11 (11a, 11b) of stave side is necessary.Therefore, in order to ensure bond area, carbon fibre reinforced composite material cross rib (upper plate) 11a of the horizontal expansion on heald frame stave, similarly, thickness H1, H2 of cross rib (lower plate) 11b, it is necessary to more than 5mm.
As shown in Figure 8, by fixing the first metal bar 20 above of rivet 22, it is to prevent for the purpose of the bonding Security Countermeasures peeled off because of some things in operation.
(5) then, the function that heald frame 1 is required, it is to ensure that woven speed.
Thereby it is ensured that much less cross section rigidity more than the cross section rigidity of the aluminum heald frame of present situation is, 1 natural frequency of heald frame stave 2 also requires that more than the aluminum of present situation.
The carbon fibre of wide variety of PAN class carbon fibre (tensile elasticity rate is at more than 235GPa) cheap in use cost makes heald frame stave 2, already known: if making the structure of the cross rib 10 (10a, 10b) being configured with more than width 5mm on the top and bottom of the hollow-core construction portion 2A of heald frame stave 2, then the cross section rigidity of above-below direction can ensure that more than aluminum.
Relative to 1 natural frequency, the tensile elasticity rate of material and density is used to become main points.
At this, because the tensile elasticity rate of aluminum is 70GPa, density is 2.7g/cm3, the average tensile spring rate using CFRP is 107GPa, and density is 1.6g/cm3If length is identical, then 1 natural frequency is in direct ratio with the root (extraction of square root) of tensile elasticity rate, inversely proportional with the root of density (extraction of square root), so 1 natural frequency of the heald frame stave 2 of the present invention becomes about 1.6 times of aluminum, it is known that 1 time natural frequency is no problem.
(6) reel frame is also required that quietness certainly.Particularly recently along with environmental problem, particularly in Europe, the requirement of the high heald frame of quietness is uprised.
On the other hand, CFRP heald frame stave, because being the compound with resin, thus few at resonance qualitly with framework basis, become the product that quietness is high.
And then, in order to improve its effect, at the hollow part of CFRP heald frame stave, except the end of installation side stay, load the areolar tissue etc. of the expanded material of carbamate, paper, it is also possible to improve effect further.
