Comprise in the warp thread bending apparatus 20 of driving mechanism 40 and warp thread bending part 30 in above-mentioned explanation, the present embodiment is configured to: when beating up (crank angle is 0 °), warp thread bending part 30 arrives most lifting position, and (crank mechanism carries out the upper dead center position driven, the position of warp thread bending part 30 indicated by the solid line in Fig. 4), when being 180 ° in crank angle, warp thread bending part 30 arrives most down position (crank mechanism carries out the lower dead point position driven, the position of warp thread bending part 30 represented by dashed line in Fig. 4).
In addition, warp thread bending part 30 is when described most lifting position (crank angle is 0 °), because of itself and the relation of the position of lower warp thread when beating up bent by its upper end-face edge, in the mode of the size making the degree of crook of lower warp thread (amount of bow) become desired (upper and lower warp thread 1,1 can be made to obtain desired tension force extent), setting warp thread bending part 30 now carries out the position etc. of installing relative to turning cylinder 50 in phase place.In addition, the shaking quantity of warp thread bending part 30 when past (returning) (amount of spin of turning cylinder 50 when past (returning)) determines with the offset of the through hole 71 of curved bar 70 relative to the driving shaft 80 of driving mechanism 40.This offset is: the warp thread bending part 30 making to be positioned at when beating up above-mentioned most lifting position with the position relationship of lower warp thread is, warp thread bending part 30 be positioned at can not because its shake when lower warp thread maximum displacement (being positioned at the state of bottom) make lower warp thread be in the position of overtension state.
And, in the present embodiment, even if warp thread bending part 30 is in the state of down position most described in being positioned at, with its position relationship with lower warp thread now, also can contact with lower warp thread and apply it to bend.Namely, when described in being positioned at when beating up, the warp thread bending part 30 of most lifting position shakes with shaking quantity because of described offset and arrives most down position, the upper end-face edge of warp thread bending part 30 is positioned at not by the top that crank angle is the lower warp path under warp thread bending part 30 limited case of 180 °.Therefore, warp thread bending part 30 to contact with lower warp thread in the whole period that main shaft 1 rotates and applies it bending.On this basis, the shaking quantity of warp thread bending part 30 is: when the maximum displacement of lower warp thread, obtains and applies by warp thread bending part 30 position that the tension force of the lower warp thread bent can not be excessive when maximum displacement.In addition, in the warp thread bending apparatus 20 being set with most lifting position and shaking quantity as mentioned above, in the present embodiment, be the phase place of the turning cylinder 50 of about 90 ° in crank angle, the upper end-face edge of warp thread bending part 30 is positioned at the height and position of warp W.Therefore, in the scope that crank angle is 0 ° to 90 °, the upper end-face edge of warp thread bending part 30 is positioned at the top of warp W.
Fig. 5 represents the state of the warp thread 1 when beating up.In addition, the elliptical tube 6c of the front side of menelipsis device 6 is only shown in Figure 5.In addition, the path 1c of upper warp thread not being provided with when to be in maximum open in warp thread bending apparatus of the present invention (warp thread bending part) the situation represented by dashed line and path 1d of lower warp thread.In addition, the path 1e of the lower warp thread be not provided with in warp thread bending apparatus of the present invention (warp thread bending part) situation represented by dashed line in the warp let-off side (jockey pulley 5 side) by warp thread 1 compared with heald frame (heddle (heald) 7a).
As shown in the figure, under obtaining state that menelipsis device 6 is configured at position near jockey pulley 5 by the desired effect such as warp thread alignment, compare and comprise in the loom of warp thread bending apparatus 20 described, only limiting the warp path of above-below direction with the elliptical tube 6c of menelipsis device 6 by the warp let-off side of warp thread 1 compared with heald frame, lower warp thread fully can be made to bend, and the Tension Difference of upper and lower warp thread can be made to become the Tension Difference that can obtain desired beating up property.In addition, be configured at the warp thread bending apparatus 20 of the present embodiment, following warp thread is curved object, at lower warp thread along with the harness motion of warp thread 1 while displacement downwards, warp thread bending part 30 also shakes displacement downwards, therefore, can prevent lower warp thread under maximum displacement state, becoming the state of overtension downwards, and can prevent from producing the problems such as lower warp break because of the state of this overtension.In detail as follows.
As mentioned above, become the open curve on the drive pattern basis of heald frame in the present embodiment as shown in Figure 2, in this example embodiment, when being about 70 ° to about 165 ° in crank angle, the state of lower warp thread in maximum displacement downwards.In addition, Fig. 6 represents the shake displacement state of the warp thread bending part 30 of warp thread bending apparatus 20 to represent together with lower warp thread 1, represents four kinds of different conditions (A, B, C, D position) of the warp thread bending part 30 of shake displacement with three solid lines and dotted line.In addition, the A positional representation warp thread bending part 30 shown in solid line is in the state (position of warp thread bending part 30) of the warp thread bending apparatus 20 of most lifting position (crank angle is 0 °); B positional representation crank angle shown in solid line is the state (position of warp thread bending part 30) of the warp thread bending apparatus 20 of 70 °.In addition, C positional representation crank angle shown in solid line is the state (position of warp thread bending part 30) of the warp thread bending apparatus 20 of 165 °, and the D positional representation crank angle shown in dotted line is the state (position of warp thread bending part 30) of the warp thread bending apparatus 20 of 90 °.In addition, in Fig. 6, dotted line E represents the path of lower warp thread 1, this path be when warp thread bending part 30 is fixed on A position under warp thread 1 maximum displacement downwards time path.
As shown in the figure, on the A position that (crank angle is 0 °) can obtain desired amount of bow when beating up, fixed configurations has a warp thread bending part 30, after this along with the displacement downward of lower warp thread 1, amount of bow increases, the tension force of lower warp thread 1 rises, and under the state of the maximum displacement downwards under (path of dotted line E) tension force of warp thread 1 become maximum.And, in this case, according to kind and the weaving condition of warp thread 1, lower warp thread 1 overtension may be caused, produce the problems such as lower warp thread 1 fracture.
Relative to this, according to the warp thread bending apparatus 20 of the present embodiment along with the displacement downwards of lower warp thread 1, warp thread bending part 30 is displacement downward also, therefore, amount of bow can be suppressed to increase, compare the state that warp thread bending part 30 is fixed on A position, tension force when lower warp thread 1 is in maximum displacement state downwards (state of B position) reduces.And, as shown in the figure, from the moment (crank angle is about 70 °) that lower warp thread 1 arrives maximum displacement position downwards play keep this position during (during being about 165 ° to crank angle), warp thread bending part 30 is displacement downwards further towards C position, therefore, the case of bending of lower warp thread 1 is to the change of mitigation direction.Therefore, in illustrated example, the amount of bow of the lower warp thread 1 of warp thread bending part 30 under the state (crank angle is 70 °) of B position is slightly larger than the amount of bow of the lower warp thread 1 when A position (when beating up), the tension force when warp tension ratio that lower warp thread 1 arrives the maximum displacement position moment downwards beats up slightly rises, but this state can not continue, the tension force of lower warp thread 1 therefore after relaxed through yarn bending part 30 displacement downwards, arrive the C position moment at warp thread bending part 30, the tension force of the lower warp thread 1 when the warp tension ratio of lower warp thread 1 beats up is low.
The warp thread bending apparatus 20 of the present embodiment according to the above description, the Tension Difference of the warp thread up and down 1,1 when beating up can be made to become the Tension Difference that can obtain desired beating up property, and effectively can prevent the problems (reason producing this problem is that lower warp thread is overtension state) such as lower warp thread is cut off during maximum displacement state downwards.In addition, in the present embodiment, warp thread bending part 30 and the turning cylinder 50 supporting this warp thread bending part 30 are configured at the below of warp (longitude yarn row) W, therefore, desirable following effect: the device configuration in loom is more simple, and warp thread bending part 30 and turning cylinder 50 can not hinder when cracked ends the repair operation that warp thread 1 carries out.In addition, as mentioned above, the action of warp thread bending part 30 arrives most down position when being 180 ° in crank angle, afterwards, its direction of displacement reverses, shake displacement upward, when the crank angle of warp thread 1 in closed configuration is 300 °, warp thread bending part 30 is in the state contacted with all warp thread 1.Afterwards, the warp thread 1 as the upper warp thread forming Warp opening before remaining silent becomes lower warp thread, and warp thread bending part 30 mainly applies bending to this lower warp thread because of shake displacement afterwards.
Above an embodiment of warp thread bending apparatus of the present invention is illustrated, but the present invention is not limited in above embodiment (described embodiment), also can carry out following distortion and implement.
(1) in the above-described embodiments, warp thread bending part 30 is configured at the below of longitude yarn row, lower warp thread is applied bending, but the configuration of warp thread bending part 30 is not limited in as the below being configured at longitude yarn row in above-described embodiment, allow as long as form, also it can be made to be supported above warp W, be configured at the top of longitude yarn row, upper warp thread be applied bending.That is, from the angle of beating up property, as long as there is desired Tension Difference when beating up between upper and lower warp thread 1,1, the situation that lower warp tension is higher is not limited in, even if when upper warp tension is higher, also beating up property can be improved.
In addition, as mentioned above, in the present invention, do not limit the configuration (applying bending warp thread 1 is upper warp thread or lower warp thread) of the above-below direction for longitude yarn row of warp thread bending part 30, therefore, formed in the upper warp thread of Warp opening and lower warp thread below, in the vertical direction using the warp thread (the lower warp thread of described embodiment) 1 of warp thread bending part 30 side as " side's warp thread ", using the warp thread 1 of its opposition side as " the opposing party's warp thread ".Wherein, because the upper-lower position of warp thread 1 reverses according to harness motion, therefore, described " side's warp thread " and " the opposing party's warp thread " are not always identical warp thread 1.
(2) in the described embodiment, driving mechanism 40 is configured to: make warp thread bending part 30 come and go shake displacement by adopting the driving mechanism 40 of offset crank mechanism.But the structure of driving mechanism 40 is not limited in the structure so adopting offset crank mechanism, as the structure that the jack back 60 made in described embodiment shakes, such as, also cam mechanism can be used.
In addition, in the described embodiment, driving mechanism 40 is configured to: comprise by the turning cylinder 50 of round rotating drive, this turning cylinder 50 is provided with warp thread bending part 30.But the support of driving mechanism 40 pairs of warp thread bending parts 30 forms to be not limited in be carried out via turning cylinder 50, as long as warp thread bending part 30 has higher rigidity, and producing because of the tension force of warp thread 1 and bending wait impact less, also can be the structure that the both ends of warp thread bending part 30 are supported on driving mechanism 40.As such structure, such as, can consider both ends bar being fixed on warp thread bending part 30 length direction, and shake this bar of driving etc. by driving mechanism 40.
In addition, be configured in the described embodiment be shaken by driving mechanism 40 drive warp thread bending part 30, but driving mechanism 40 is not limited in shake and drives warp thread bending part 30, also can be make warp thread bending part 30 come and go the structure of displacement in above-below direction linearity.As such structure, such as can consider the structure that the turning cylinder 50 of described embodiment or warp thread bending part 30 are supported by stay etc. at the both ends of its length direction to make this stay come and go displacement in above-below direction linearity by ball screw mechanism and rack and pinion mechanism etc.Wherein, this linearity direction of displacement is not limited in plummet direction, also can with plummet direction angulation.
In addition, warp thread bending part 30 as above is not limited in the structure on end described in two sides that driving mechanism 40 is fixed in warp thread bending part 30 in the both ends of the length direction structure be supported on driving mechanism 40, as long as warp thread bending part 30 has higher rigidity, and can not inclination be produced at the Support Position warp thread bending part 30 with driving mechanism 40, also can be the end that driving mechanism 40 is only fixed in the described end of warp thread bending part 30, and the other end be by the structure of guiding parts guiding displacement.
(3) in the described embodiment, the displacement of warp thread bending part is configured to: warp thread bending part 30 contacted with lower warp thread in the main axis whole period of one week, applies bending to lower warp thread.As long as but warp thread bending part 30 above-below direction displacement drive structure at least when beating up warp thread bending part 30 to contact with one warp thread 1 and bending structure applied to it.Such as also can in the structure of described embodiment, increase the shaking quantity of warp thread bending part 30, become the moment of most down position at warp thread bending part 30 and to comprise before and after it during moment, making warp thread bending part 30 leave one warp thread.
In addition, become most lifting position moment and during comprising this moment, warp thread bending part 30 is not limited in and only contacts with one warp thread 1 and only apply one warp thread 1 bending, also can contact with the warp thread 1,1 of both sides and apply the warp thread 1,1 of both sides bending.Even if in this case, with the relation in the path of the configuration of warp thread bending part 30 and each warp thread 1, the tension force of one warp thread 1 is also large than the tension force of the opposing party warp thread 1, becomes the state producing Tension Difference between upper and lower warp thread 1,1.
In addition, be configured in the described embodiment: when beating up (crank angle is 0 °), the drive pattern becoming most lifting position (amount of bow of warp thread 1 is maximum) with warp thread bending part 30 makes warp thread bending part 30 in above-below direction displacement drive, but warp thread bending part 30 is not limited in this at the drive pattern of the structure of above-below direction displacement drive, as long as desired beating up property can be obtained when beating up by making warp thread or lower warp thread produce bending (Tension Difference of upper and lower warp thread 1,1).In addition, in the experiment that inventors of the present invention carry out, in the structure of described embodiment, the crank angle of the maximum deflection amount of warp thread 1 is set to 330 °, 345 °, 0 °, 30 ° and confirms beating up property, consequently, (crank angle is 0 ° in the case of all the described embodiments, when the amount of bow of lower warp thread is maximum), best beating up property can be obtained, even if but in crank angle beyond described 0 °, the beating up property that can not produce quality problems of weaving cotton cloth also can be obtained.
In addition, in the described embodiment, the most lifting position of warp thread bending part 30 is positions that the upper end-face edge of warp thread bending part 30 is positioned at above warp W, as long as the Tension Difference of the warp thread up and down 1,1 in moment can obtain desired beating up property but the most lifting position of warp thread bending part 30 makes to beat up.More particularly, as mentioned above, the beating up property of weft yarn is by the tension deviation influence of the warp thread up and down 1,1 in moment of beating up.At this, it is that the tension force applying the one warp thread 1 bent by warp thread bending part 30 determined that this Tension Difference has more than, and it is also relevant to the tension force of now the opposing party's warp thread 1.In addition, if displacement when making warp thread 1 opening and setting tension force identical, the tension force of one warp thread 1 is namely corresponding with the amount of bow of warp thread bending part 30, and the most lifting position of this amount of bow and warp thread bending part 30 is corresponding.Therefore, as long as the most lifting position of warp thread bending part 30 is according to above-mentioned conditional decision, in this case, the present invention is not limited in as in above-described embodiment, the upper end-face edge of warp thread bending part 30 is positioned at the position than warp W more top.
(4) in the present embodiment, warp thread bending apparatus is configured to: warp thread bending apparatus 20 comprises makes warp thread bending part 30 come and go the driving mechanism 40 of displacement drive at above-below direction, warp thread bending part 30 coordinates the harness motion of warp thread in above-below direction displacement, but warp thread bending apparatus of the present invention is not limited in such structure comprising driving mechanism 40, also can be configured to: in the vertical direction, make fixed configurations on the bending position of warp thread 1 have warp thread bending part 30 in the moment of beating up.Namely, according to the kind etc. of weaving condition (setting tension force etc.) and warp thread 1, tension force when the maximum displacement of warp thread 1 is not excessive, even if or overtension also there will not be when weaving aspect problem, warp thread bending part 30 in the vertical direction also can fixed configurations in applying bending position in the mode making the Tension Difference of upper and lower warp thread 1,1 become desired degree when beating up to warp thread 1.
In addition, warp thread bending part 30 be not limited in as described in plate-shaped member in embodiment, also can be the cross section in direction orthogonal to the longitudinal direction be circular or oval bar-shaped (cylindric) parts, can also be described cross section be square angle columnar part (wherein, circle need be scraped in the top contacted with warp thread 1).
In addition, it is parts on a straight line that the height and position of the upper end-face edge contacted with warp thread 1 is identical with the total length of whole length direction in the vertical direction that warp thread bending part 30 is not limited in, also can be: different from the upper end-face edge of the central portion of length direction at the height and position of upper end-face edge at least both ends of length direction, and the height and position of the upper end-face edge at these both ends is in the vertical direction to the shape that longitude yarn row lateral deviation is put, more particularly, when warp thread bending part 30 is configured on the downside of longitude yarn row, the height and position at both ends is higher than central portion, when warp thread bending part 30 is configured on the upside of longitude yarn row, the height and position at both ends is lower than central portion.Described in specific as follows.
Usually, in longitude yarn row, the tension force being positioned at the warp thread at the both ends part of edge (formation weave cotton cloth) in woven pieces direction trends towards lower than the tension force of the warp thread being positioned at central portion.In addition, the warp thread bending part 30 of warp thread bending apparatus of the present invention is at the longer parts of length direction, therefore, impact by warp tension may produce flexure, in this case, the height and position of its upper end-face edge viewed from front, the height and position at described both ends is lower than the height and position of central portion.Therefore, consequently, under the state being applied to bend by warp thread bending part 30, the degree of crook of the warp thread 1 being positioned at the both ends in woven pieces direction in longitude yarn row is less than the degree of crook of the warp thread 1 being positioned at central portion.Therefore, as mentioned above, when warp thread bending part 30 produces flexure, even if under the state being applied to bend by warp thread bending part 30, in conjunction with described trend, the tension force of the warp thread 1 being positioned at described both ends of longitude yarn row also can become large with the difference of tension force of the warp thread 1 being positioned at central portion, and woven quality of weaving cotton cloth likely can be caused to reduce.In addition, if fully do not increase tension force, the possibility of result can cause at warp thread 1 opening at described both ends bad, and wefting insertion mistake occurs.
Therefore, consider the problems such as described flexure, also can make the height and position of the upper end-face edge at least both ends compared with the height and position of the upper end-face edge of central portion to the mode that longitude yarn row lateral deviation is put, the shape of warp thread bending part 30 is such as set to bending shape.In addition, only can also make the height and position of the upper end-face edge at both ends compared with other parts to the mode that longitude yarn row lateral deviation is put, warp thread bending part 30 is configured to be provided with step.
(5) in the described embodiment, loom as prerequisite is set to drive heald frame (applying harness motion to warp thread) according to the open curve (opening pattern) shown in Fig. 2, but in the loom premised on the present invention, open curve for applying harness motion to warp thread is not limited in open curve as shown in Figure 2, as long as opportunity warp thread being become open state is set as different from the opportunity (when beating up) of by reed weft yarn being squeezed into fell, can be any open curve.Therefore, the opportunity that also warp thread can be become open state was set as after the time of beating up.
In addition, in the described embodiment, describe and warp W is set as horizontal direction, but the loom premised on the present invention is not limited in this, also can be configured to warp W is tilted.In addition, when warp W tilts, upper and lower warp thread produces Tension Difference because respective path is different.That is, when be configured to make fell side lower than jockey pulley side with the loom making warp W tilt, on the warp tension ratio of the lower warp thread in the warp thread of opening-like state, the tension force of warp thread is high.Therefore, the amount of bow of warp thread bending part by being configured to be applied to bend the Tension Difference increasing upper and lower warp thread to lower warp thread by warp thread bending part, or is set to the Tension Difference that also can obtain with described embodiment identical up and down warp thread less of the amount of bow of described embodiment by such loom.
The present invention is not limited in described embodiment and variation described above, can do suitable change in the scope not departing from its central idea.
