Technical field

The present invention relates to the cloth winding tension regulator that loom uses, particularly relate to possess can be supported in rotationally on loom frame and according to the change of the coil diameter (cloth beam adds the diameter of batching) of the fabric be wound on cloth beam (batching) and the coil diameter of rotating follow bar and adjust the cloth winding tension regulator of the batching torque adjustment arrangement of the driving torque (batching torque) of cloth beam according to the amount of spin that above-mentioned coil diameter follows bar.

Background technology

As the prior art of above-mentioned cloth winding tension regulator, there is the technology disclosed in patent document 1.This cloth winding tension regulator disclosed in patent document 1 possesses: the feeler of following bar as above-mentioned coil diameter; And batching torque adjustment arrangement, this batching torque adjustment arrangement possesses and connects by the rotary body of loom main shaft (former dynamic motor) rotary actuation and the friction transfer unit of axle that links with cloth beam, and according to the coil diameter along with batching (hereinafter also referred to as " coil diameter ".) the amount of spin of feeler of increase change the transmitting torque of friction transfer unit.And, according to this cloth winding tension regulator, the increase of coil diameter that feeler causes with the carrying out of weaving and rotating, the pressing force of the friction plate of the friction transfer unit of batching torque adjustment arrangement is increased pro rata according to the amount of spin of this feeler, its result, batching torque is increased (the single dotted broken line I in Fig. 5 (a)) pro rata, the tension force (cloth winding tension) of adjustable batching according to the increase of coil diameter.

In addition, cloth winding tension is calculated divided by coil diameter by batching torque.If namely cloth winding tension is set to F, batching torque is set to T, coil diameter is set to D, then obtain with F=T/D.In addition, in loom, about the adjustment of the cloth winding tension of the carrying out (increase of above-mentioned coil diameter) along with weaving, generally wish that cloth winding tension reduces pro rata, in other words, wish that the minimizing degree of the cloth winding tension that the increase of the coil diameter of per unit coil diameter recruitment causes is (hereinafter also referred to as " minimizing degree ".) fixing.

Wherein, the recruitment being meant to prespecified coil diameter of " unit coil diameter recruitment " mentioned here.Therefore, being meant to of " increase of the coil diameter of unit coil diameter recruitment ", such as, when unit coil diameter recruitment is set to 100mm, coil diameter is increased to the situation of 200mm from 100mm or is increased to the situation etc. of 300mm from 200mm.In addition, " increase of the coil diameter of unit coil diameter recruitment " will be also somebody's turn to do below referred to as " unit coil diameter increases ".In addition, being meant to of " the minimizing degree of the cloth winding tension that the increase of the coil diameter of per unit coil diameter recruitment causes ", the cloth winding tension in the last moment (coil diameter in this moment: De) in constituent parts coil diameter increases relative to the initial moment (coil diameter in this moment: Ds) cloth winding tension to the changing ratio (being equivalent to the inclination of the curve map of Fig. 5 (b)) reducing direction.Specifically, it is the following meaning, such as, if unit coil diameter recruitment is set to 100mm, then the value of cloth winding tension during De=200mm relative to the value of the cloth winding tension when changing ratio of the value of cloth winding tension during Ds=100mm or De=300mm relative to the changing ratio etc. of the value of cloth winding tension during Ds=200mm.

In addition, if the cloth winding tension in above-mentioned initial moment (coil diameter: Ds) is set to Fs, cloth winding tension time above-mentioned last moment (coil diameter: De) is set to Fe, then above-mentioned minimizing degree (changing ratio) based on the difference of Fs and Fe (hereinafter also referred to as " Tension Difference ".)。On the other hand, if consider, Fe is to the relation of Fs, then the batching torque in above-mentioned initial moment is being set to Ts, the batching torque in above-mentioned last moment is being set to Te, then as mentioned above cloth winding tension is calculated divided by coil diameter by batching torque, therefore both ratio: Fe/Fs becomes the ratio of Te to Ts: Te/Ts is divided by the ratio of De to Ds: De/Ds.Namely Fe/Fs=(Te/Ts)/(De/Ds), is become.Therefore, if the ratio of above-mentioned batching torque is set to Tr (=Te/Ts), the ratio of coil diameter is set to Dr (=De/Ds), then the relation of Fs and Fe becomes Fe=Tr/Dr × Fs.And if mentioned strain is poor, namely, Fs-Fe=(1-Tr/Dr) × Fs is fixing when per unit coil diameter increases, then above-mentioned minimizing degree is fixing.

Further, in the cloth winding tension regulator disclosed in patent document 1, in order to make, above-mentioned minimizing degree is more close fixing state, namely, as far as possible the mentioned strain of reduction per unit coil diameter increase is poor, adopts structure as described above.Specifically as follows.

Such as, the double dot dash line J1 of batching torque as shown in Fig. 5 (a), terminate, for when fixing, the double dot dash line J2 of above-mentioned minimizing degree as shown in Fig. 5 (b), to diminish gradually with the increase of coil diameter to winding from the winding of fabric.Its reason is, as mentioned above, above-mentioned minimizing degree is poor based on mentioned strain, in addition, its Tension Difference is multiplied by above-mentioned (1-Tr/Dr) by the Fs (=Ts/Ds) in the increase of constituent parts coil diameter to be obtained, but when batching torque is fixing, the ratio of above-mentioned batching torque is fixing (Tr=Te/Ts=1), and therefore mentioned strain difference becomes (1-1/Dr) × Fs.

And, because the ratio Dr (=De/Ds) of above-mentioned coil diameter when per unit coil diameter increases diminishes (such as along with coil diameter becomes to form greatly inversely, if unit coil diameter recruitment is set to 100mm, then the ratio Dr of above-mentioned coil diameter becomes 2 times when coil diameter is increased to 200mm from 100mm, becomes 1.5 times when coil diameter is increased to 300mm from 200mm.In addition, about 1.33 times are become when coil diameter is increased to 400mm from 300mm, 1.25 times are become) when coil diameter is increased to 500mm from 400mm, therefore above-mentioned (1-1/Dr) when per unit coil diameter increases diminishes gradually with the increase of coil diameter, in addition, Fs also diminishes gradually with the increase of coil diameter.Therefore, the mentioned strain difference that per unit coil diameter increases diminishes greatly and gradually along with coil diameter becomes, and above-mentioned minimizing degree (changing ratio) diminishes gradually with the increase of coil diameter.

Like this, if it is fixing that batching torque starts to winding end from winding, then above-mentioned minimizing degree diminishes gradually with the increase of coil diameter, and cloth winding tension forms with the increase of coil diameter and reduces inversely.Further, its result, is being wound in the generation of the fabric on cloth beam fold, the problem of quality decline producing the fabric of weaving and so on.

Therefore, in the cloth winding tension regulator disclosed in patent document 1, in order to alleviate the change of above-mentioned minimizing degree when per unit coil diameter increases, and adopt structure as above, batching torque is increased pro rata according to the increase of coil diameter.And, according to this structure, compared with being fixing situation with batching torque, the ratio Dr of above-mentioned coil diameter when per unit coil diameter increases is identical with the change of the increase of coil diameter, but it is the value that fixing situation is large that the ratio Tr of above-mentioned batching torque becomes than the batching torque when constituent parts coil diameter increases, therefore mentioned strain difference when per unit coil diameter increases diminishes, and as shown in the single dotted broken line I in the chart of Fig. 5 (b), above-mentioned minimizing degree is alleviated.

Summary of the invention

Invent problem to be solved

But, even if according to the cloth winding tension regulator disclosed in patent document 1, although above-mentioned minimizing degree and batching torque are alleviated (diminishing) compared with fixing situation, but still diminish gradually with the increase of coil diameter, therefore can not fully prevent the fabric be wound on cloth beam from producing fold.Specifically as described below.

In the cloth winding tension regulator disclosed in patent document 1, the amount of spin of batching torque and the rotation with feeler and bar in the batching torque adjustment arrangement of rotating changes pro rata, but in this cloth winding tension regulator, become above-mentioned bar by be fixed with feeler and with the rotation of feeler the structure that the axle that rotates rotates.Specifically, above-mentioned bar to become relative to the above-mentioned axle being fixed with feeler in the mode that can not relatively rotate by the structure supported.Therefore, in this cloth winding tension regulator, become the structure that above-mentioned bar rotates with amount identical with feeler, on the other hand, feeler rotates with ormal weight pro rata when per unit coil diameter increases, and therefore batching torque increases pro rata.

At this, about each interval that per unit coil diameter increases, such as, unit coil diameter recruitment is set to 100mm, the interval that coil diameter is increased to 200mm from 100mm is set to the first interval, the interval that coil diameter is increased to 300mm from 200mm is set to the second interval, the interval that coil diameter is increased to 400mm from 300mm is set to the 3rd interval, the interval that coil diameter is increased to 500mm from 400mm is set to the 4th interval, the cloth winding tension that winding starts (the above-mentioned initial moment in the first interval) is set to F1, batching torque is set to T1, afterwards, when per unit coil diameter increases, batching torque just increases pro rata with a, namely, if the batching torque in the above-mentioned initial moment in each interval is T1+a in the second interval, be T1+2a in the 3rd interval, be T1+3a in the 4th interval, the then cloth winding tension Fs in the above-mentioned initial moment in each interval and the Tension Difference R1 of the cloth winding tension Fe in above-mentioned last moment, R2, R3, R4 is R1=1/2 × { (T1-a)/T1 × F1} in the first interval, be R2=1/6 × { (T1-a)/T1 × F1} in the second interval, be R3=1/12 × { (T1-a)/T1 × F1} in the 3rd interval, be R4=1/20 × { (T1-a)/T1 × F1} in the 4th interval.By the way, when batching torque is fixing, above-mentioned a is 0.

Can be clear and definite from above-mentioned calculating formula: the mentioned strain difference of the cloth winding tension corresponding with the minimizing degree of cloth winding tension when above-mentioned a be fixing situation, namely, batching torque increase pro rata when per unit coil diameter increases, { (T1-a)/T1 × F1} becomes constant, change to occur in a diminishing manner, be 1/2 of this constant in the first interval, be 1/6 of this constant in the second interval, the 3rd interval for this constant 1/12, the 4th interval be 1/20 of this constant, change with diminishing gradually.Therefore, as the cloth winding tension regulator of patent document 1, in the structure that batching torque is increased pro rata according to the increase of coil diameter, terminate as fixing situation is identical from reeling to reeling with batching torque, above-mentioned minimizing degree does not become close to fixing, and cloth winding tension forms with the increase of coil diameter and reduces inversely.Therefore, even if according to the cloth winding tension regulator of patent document 1, can not fully prevent from being wound on fabric on cloth beam and produce fold.

In addition, in patent document 1, also disclose and to make along with the increase of coil diameter batching torque with conic section ground (inversely) technology of increasing.Specifically, be configured in the cloth winding tension regulator disclosed in patent document 1, by change to the friction plate of friction transfer unit to and the arm of pressing force and the angle of intersection of adjusting lever that links with this arm, and make to change its length of above-mentioned bar to the spring of adjusting lever side reinforcing relative to each abutted position of adjusting lever at above-mentioned bar, thus the active force changed at the spring of above-mentioned each abutted position, and then change the pressing force of arm to the friction plate of friction transfer unit effect.

But, as mentioned above, because above-mentioned bar is supported in the mode that can not relatively rotate relative to the above-mentioned axle being fixed with feeler, therefore, as mentioned above when making the active force of spring change with bar relative to the displacement of the abutted position of adjusting lever, due to the reaction force of spring, the abut power of feeler in the abutted position of feeler with fabric to fabric changes, it becomes reason and causes the state of the fabric reeled to change, and likely brings harmful effect to the quality of fabric.

In view of the actual conditions of existing cloth winding tension regulator such above, the object of this invention is to provide a kind of cloth winding tension regulator of loom, it need not make the active force of above-mentioned bar effect to be changed to the batching torque just can suitably changed when per unit coil diameter increases by spring, thus cloth winding tension is reduced roughly pro rata, can prevent the fabric be wound on cloth beam from producing fold.

Further, about the position of back shaft 45 and the above-mentioned abutted position of roller 46, all to meet above-mentioned (1), the mode of prerequisite of (2) determines.Wherein, meet above-mentioned (1), the position of back shaft 45 of (2) and the above-mentioned abutted position of roller 46 and not only have specific one position, about respective position, there is the scope that can set.Therefore, such as there is following consideration about respective position, namely, in the scope meeting above-mentioned (1) determine the position of back shaft 45, and, the above-mentioned abutted position etc. of decision roller 46 the scope meeting above-mentioned (2) in.In addition, when determining the above-mentioned abutted position of the position of back shaft 45 and roller 46, be accompanied by this, determine that coil diameter is followed the arrangement angles (inclination relative to fell 2 side or fell 2 opposition side) of the line segment N in the initial configuration of bar 42 and follows the amount of spin (coil diameter follows whole amounts of spin of bar 42) of bar 42 from the coil diameter during winding to start at the end of reeling this.

By the way, in the example in the figures, as the result of the prerequisite according to above-mentioned (1), (2), the initial configuration of bar 42 is followed about coil diameter, the Support Position (position of back shaft 45) of back shaft 45 is configured at axle center 6a relative to cloth beam 6 roughly above vertical, and the rotation direction opposition side that line segment N (coil diameter follows the bearing of trend of the support portion 42a of bar 42) follows bar 42 relative to vertical to coil diameter tilts about 4 °.

In addition, in the present embodiment, about the initial configuration of dwang 43, set premised on following (3) ~ (5).

(3) first, in the present embodiment, connecting pin 44 becomes and is positioned at because of the deadweight of dwang 43 state that coil diameter follows the lower end (position near above-mentioned border) of the elongated hole 42e of the support portion 42a of bar 42.Namely the connecting pin 44, in initial configuration is set in the lower end of elongated hole 42e in the coil diameter position of following on bar 42 (support portion 42a).In other words, dwang 43 has has center to the intercalation of the through hole 43a of back shaft 48 to have the Distance geometry at the center of the through hole 43b of connecting pin 44 to follow the roughly the same length dimension of the distance of the bottom of the elongated hole 42e of bar 42 from the axle center 48a of back shaft 48 to the coil diameter initial configuration from intercalation.

(4) in addition, as mentioned above, in the present embodiment, initial configuration is set as that angle [alpha] is 100 °.Therefore, the back shaft 48 (the second back shaft) of support rotating bar 43 is set to, under connecting pin 44 is as described above positioned at the state that coil diameter follows the lower end of the elongated hole 42e of the support portion 42a of bar 42, axle center 48a (axle center of the second back shaft) is arranged in and is followed line segment N under state that bar 42 is in initial configuration the forms 100 ° line (line that Fig. 4 represents with double dot dash line: be also called " datum line L1 " by this line below in the rotation direction side that coil diameter follows bar 42 by the axle center 44a of this connecting pin 44 with coil diameter.) on.

(5) and, back shaft 48 is based on above-mentioned condition (a), and the coil diameter line segment N angulation α followed in the position of bar 42 be located at the end of line segment K and winding is the position of less than 195 °.Specifically, such as based on the following position obtaining back shaft 48, in addition, according to above-mentioned (3), based on the position of back shaft 48, determine the length dimension (distance from center to the center of through hole 43b of through hole 43a) of dwang 43.

First, follow according to the coil diameter determined as mentioned above whole amounts of spin that the arrangement angles of the line segment N in the initial configuration while starting (winding) of bar 42 and coil diameter follow bar 42, the coil diameter at the end of obtaining winding follows the arrangement angles of the support portion 42a of bar 42.Therefore, if draw the straight line parallel with the bearing of trend of the support portion 42a at the end of this winding by the axle center 45a of back shaft 45, then line L2 represented by dashed line in Fig. 4 is become.By the way, connecting pin 44 is positioned at and is formed at support portion 42a and the elongated hole 42e of longer on the bearing of trend of support portion 42a (extension), and therefore at the end of winding, axle center 44a is positioned on this dotted line L2.Therefore, line segment N is also positioned on dotted line L2.In addition, the position P1 that dotted line L2 and datum line L1 intersect, owing to being provided with back shaft 48 in this position, is that angle [alpha] becomes the position of 180 ° at the end of winding.

And obtaining angle [alpha] at the end of winding becomes the position of the back shaft 48 of 195 °.In addition, angle [alpha] is 195 ° and refers to, formed the angle of 165 ° in the rotation direction opposition side that coil diameter follows bar 42 relative to dotted line L2 by the straight line of the axle center 44a of the connecting pin 44 of the position at the end of the axle center 48a of back shaft 48 and winding, so in the diagram, if follow the imaginary line of the angle of the rotation direction opposition side extraction formation 165 ° of bar 42 in coil diameter relative to dotted line L2, then the intersection point of this imaginary line and datum line L1 becomes the position that angle [alpha] at the end of reeling is the axle center 48a of the back shaft 48 of 195 °, the position of the axle center 44a of the connecting pin 44 at the end of the intersection point of imaginary line and dotted line L2 becomes winding.

Wherein, because the distance of the axle center 48a to the axle center 44a of connecting pin 44 from back shaft 48 is always fixing, therefore this imaginary line needs to draw as follows, namely, should the point on the datum line L1 that be obtained by imaginary line and the point on dotted line L2 become the axle center 44a of the connecting pin 44 when starting from the point on this datum line L1 to winding distance and from the point datum line L1 to the equidistant position of the point on dotted line L2.Therefore, as the result of this imaginary line of drawing based on this, this imaginary line becomes line L3 indicated by the solid line in the diagram.Further, the intersection point P2 of this solid line L3 and datum line L1 becomes the position that angle [alpha] at the end of reeling is the axle center 48a of the back shaft 48 of 195 °.In addition, the position of the axle center 44a of the connecting pin 44 at the end of the intersection point P3 of solid line L3 and dotted line L2 becomes winding.

And, as mentioned above, when the axle center 48a of back shaft 48 is positioned on datum line L1, by the mode being positioned at a P1 with axle center described above, back shaft 48 is set, thus the angle [alpha] at the end of winding becomes 180 °, it can thus be appreciated that, be positioned at axle center 48a the mode of 44a side, axle center comparing the connecting pin 44 that the some P2 obtained as mentioned above leaves when winding starts and back shaft 48 is set, thus angle [alpha] at the end of winding is less than 195 °.And, consider the restriction (position etc. of back shaft 48 can be configured) of the design aspect in mechanical structure, the position of setting back shaft 48.

According to above (3) ~ (5), about the initial configuration of dwang 43, determine the arrangement angles of the position of back shaft 48, the length (distance of the axle center 48a of back shaft 48 and the axle center 44a of connecting pin 44) of line segment K and dwang 43 (line segment K), thus, the amount of spin (whole amounts of spin of dwang 43) starting the dwang 43 at the end of reeling during this from winding is determined.

By the way, in the present embodiment, as the result of the prerequisite according to above-mentioned (3) ~ (5), about the initial configuration of dwang 43, the Support Position (position of back shaft 48) of back shaft 48 is the position in less than 195 ° such positions, to include the design aspect in above-mentioned mechanical structure in restriction as the angle [alpha] at the end of winding, and the angle [alpha] at the end of being configured in winding is the position of 162 °.

In addition, in batching torque adjustment arrangement 10, according to this apparatus structure, about the amount of spin (whole amounts of spin of follower lever 28) starting the follower lever 28 at the end of reeling during this from winding, whole amounts of spin desired by existence, therefore in the present embodiment, the diameter of the synchronous pulley 49,50 in setting rotary transfer machine 52, so that as mentioned above with determining whole amount of spin of dwang 43 and making whole amounts of spin of follower lever 28 become desired whole amounts of spin relative to whole amounts of spin of this dwang 43.

As mentioned above, in the loom comprising cloth winding tension regulator 10, this cloth winding tension regulator 10 possesses the linkage 41 of the initial configuration being set with each linkage component and has the follower lever 28 linked with the dwang 43 in this linkage 41, with the beginning of weaving, start to utilize cloth beam 6 wound fabric 1, then, with the carrying out of weaving, the coil diameter of the batching 1 of cloth beam 6 increases gradually.According to the increase of the coil diameter of this batching 1, in another side of abutting part 42c, the coil diameter abutted with batching 1 via roller 46 is followed bar 42 follows bar 42 rotation direction along the coil diameter that the arrow X with dotted line in Fig. 1 represents and is rotated towards fell 2 side.

By the way, in the present embodiment, as mentioned above, in the process that the coil diameter of batching 1 increases, angle γ (line segment B follows the rotation direction opposition side angulation of bar 42 in coil diameter relative to line segment A: with reference to Fig. 1) remains roughly fixing, thus coil diameter is followed bar 42 and (in the present embodiment, unit coil diameter recruitment is set to 50mm relative to the increase of the coil diameter of the unit coil diameter recruitment from winding at the end of winding.) always rotate with fixing amount of spin (in the example shown in Fig. 3 being 5.5 °).

In addition, as mentioned above, follow bar 42 rotate with coil diameter, the rotation direction of following the dwang 43 that dwang 43 that bar 42 links represents along the arrow Y with dotted line in Fig. 1 via connecting pin 44 and coil diameter is rotated towards fell 2 side.In addition, in this case, the coil diameter of following the rotation of bar 42 with the coil diameter change of following the distance between the lower end of the elongated hole 42e of the support portion 42a of bar 42 and back shaft 48 is absorbed from its lower end to upper end side displacement due to the connecting pin 44 of the linking part 47 of two linkage components in elongated hole 42e, thus, the rotation of two linkage components is allowed.Further, follow the rotation of bar 42 with coil diameter, connecting pin 44 is followed in the elongated hole 42e of the support portion 42a of bar 42 from its lower end to upper end side (back shaft 45 side) displacement in coil diameter.

In addition, follow the slewing area (start at the end of winding from winding, coil diameter follows the scope that bar 42 carries out rotating) of bar 42 in coil diameter, be set as that the angle [alpha] (coil diameter follows the line segment N in the bar 42 and line segment K in dwang 43 to follow bar 42 rotation direction side angulation in coil diameter) of 100 ° becomes 162 ° at the end of reeling in initial configuration (during winding beginning).Namely the slewing area of bar 42, is followed in coil diameter, linking second back shaft (back shaft 48) of support rotating bar 43 and the line segment K of linking part 47 relative to linking supports coil diameter and follows first back shaft (back shaft 45) of bar 42 and the line segment N of linking part 47 to be contained in more than 90 ° less than 195 ° angular range at the rotation direction side angulation α that coil diameter follows bar 42, and reel beginning time ratio reel at the end of close to 90 °.

Its result, follows bar 42 with coil diameter and rotates, and dwang 43 makes amount of spin minimizing rotate.Namely, in the slewing area (dwang 43 is followed bar 42 carry out rotating and the scope of rotating along with being started coil diameter at the end of winding from winding) of dwang 43, the mode that the amount of spin of the dwang 43 that the rotation that dwang 43 follows bar 42 with the coil diameter of adjoint per unit coil diameter recruitment obtains diminishes gradually along with the increase of coil diameter is rotated.

Specifically, as mentioned above, if unit coil diameter recruitment is set to 50mm, then the amount of spin (rotational angle: 5.5 °) that when starting from winding, at the end of (coil diameter 100mm) to winding, the amount of spin (rotational angle) of the dwang 43 of the increase (unit coil diameter increase) of the coil diameter of (coil diameter 300mm) adjoint unit coil diameter recruitment during this follows bar 42 relative to coil diameter changes (reference Fig. 3) as following (1) ~ (4).

(1) when coil diameter is increased to 150mm from 100mm, the amount of spin of (reeling after just starting) dwang 43 becomes 19 °.

(2) when coil diameter is increased to 200mm from 150mm, the amount of spin of dwang 43 becomes 9 °.

(3) when coil diameter is increased to 250mm from 200mm, the amount of spin of dwang 43 becomes 7 °.

(4) when coil diameter is increased to 300mm from 250mm, the amount of spin of (winding close to an end before) dwang 43 becomes 6 °.

As mentioned above, in the present embodiment, about the amount of spin of the dwang 43 of the adjoint unit coil diameter increase started from winding at the end of winding during this, the amount of spin (corresponding with above-mentioned (1)) of the dwang 43 that the rotation that the coil diameter that the adjoint unit coil diameter after just starting relative to reeling increases follows bar 42 obtains, the amount of spin (corresponding with above-mentioned (4)) of the dwang 43 that the rotation that the coil diameter that the adjoint unit coil diameter before winding closes to an end increases follows bar 42 obtains becomes little value.

Further, the amount of spin corresponding to dwang 43 changes as above-mentioned (1) ~ (4), and the recruitment of batching torque, as the solid line H1 as shown in Fig. 5 (a), diminishes gradually.Specifically, to start at the end of reeling during this from winding, rotate according to the increase of coil diameter with dwang 43, in batching torque adjustment arrangement 10, follower lever 28 rotates towards the abutted position of the bearing surface 27a of roller 37 pairs of pressure rods 27 of follower lever 28 from the direction that the center of rotation of pressure rod 27 is left.Thus, terminate to winding from winding, batching torque increases gradually.

In addition, in the process that follower lever 28 rotates like this, the amount of spin of follower lever 28 changes when per unit coil diameter increases with the amount of spin of dwang 43 as above-mentioned (1) ~ (4), changes with diminishing gradually when per unit coil diameter increases.Namely, the amount of spin (recruitment of batching torque) of follower lever 28 is to start from winding to change to the increase of winding end according to coil diameter in inversely proportional the mode increased.Further, as its result, the minimizing degree of cloth winding tension when per unit coil diameter increases is roughly fixing, and the solid line H2 as shown in Fig. 5 (b), cloth winding tension reduces roughly pro rata with the increase of coil diameter.Further, because cloth winding tension reduces so roughly pro rata, therefore, it is possible to prevent the fabric 1 be wound on cloth beam 6 from producing fold.

In addition, the action of dwang 43 as described above realizes according to the characteristic of the linkage of following explanation.

< is about linkage A >

First, about the above-mentioned dynamic trend in above-mentioned scope (a3), an example based on the linkage A shown in Fig. 7 is described.Wherein, in the example in the figures, driving side linkage component 53 represents with single dotted broken line, and slave end linkage component 54 represents with double dot dash line, in addition, the rotation direction of driving side linkage component 53 represents with dotted arrows V, and the rotation direction of slave end linkage component 54 dotted arrow W represents.And, Fig. 7 represents the situation that angle [alpha] changes the scope of 90 ° to 180 °, and represents the state of the unit angle (unit drive displacement amount: in illustrated example be 3.4 °) making driving side linkage component 53 respectively rotate (drive displacement) to specify.In addition, also the drive displacement of the unit drive displacement amount of driving side linkage component 53 is called " unit drive displacement " below.

As understood from this figure, in linkage A, when making driving side linkage component 53 carry out drive displacement with angle [alpha] in the mode that the scope of 90 ° to 180 ° changes, the dynamic trend that slave end linkage component 54 is expressed as follows relative to the driven displacement of this drive displacement: slave end linkage component 54 becomes large, along with close to 180 ° diminishes close to 90 ° when angle [alpha] relative to the driven displacement of unit drive displacement amount (3.4 °).Specifically, as illustrated, slave end linkage component 54 is 37.8 ° → 15.2 ° → 12.3 ° → 11.1 ° from angle [alpha] close to diminishing gradually successively 90 ° of sides relative to the driven displacement of the drive displacement (unit drive displacement) of the unit drive displacement amount of driving side linkage component 53.

Namely, linkage A as shown in Figure 7, angle [alpha] changes driving side linkage component 53 such the scope of 90 ° to 180 ° with the drive displacement of driving side linkage component 53 slewing area, slave end linkage component 54 has following characteristic relative to the driven displacement of the drive displacement of driving side linkage component 53: angle [alpha] is more better close to 90 ° of efficiency, and along with angle [alpha], close to 180 °, efficiency is deteriorated gradually.

Wherein, in linkage A, with the rotation of driving side linkage component 53, from the center of the linking part 55 of center of rotation 53a to two linkage component of driving side linkage component 53 (hereinafter also referred to " point of contact ".) part of 55a is (hereinafter also referred to " driving side part ".) length change, the part of the length of this driving side part and the center of rotation 54a of slave end linkage component 54 to point of contact 55a is (hereinafter also referred to " slave end part ".) the ratio of length that is bar ratio change, the change of this bar ratio can impact to the driven displacement of slave end linkage component 54.

In addition, when Fig. 7 of linkage A, namely, as shown in Figure 7, in linkage A, the situation of carrying out drive displacement with angle [alpha] in the mode that the scope of 90 ° to 180 ° changes about driving side linkage component 53 (is elliptically called " the linkage A of Fig. 7 " below.), the change of the driven displacement of the slave end linkage component 54 of the per unit drive displacement of the driving side linkage component 53 that the change can obtaining this bar ratio based on Figure 18 causes.

Fig. 8 is the linkage A about Fig. 7, makes the turned position of the driving side linkage component 53 of constituent parts drive displacement as one man represent the driven displacement of slave end linkage component 54 relative to the unit drive displacement of driving side linkage component 53.Namely, in fig. 8, by the drive displacement of the driving side linkage component 53 in constituent parts drive displacement with the Shape Representation making its starting position consistent.Wherein, in linkage A, as mentioned above, in constituent parts drive displacement, the length of the above-mentioned driving side part of driving side linkage component 53 changes, therefore, in fig. 8, about the length of the above-mentioned driving side part of the driving side linkage component 53 in constituent parts drive displacement, be by the length equalization of the above-mentioned driving side part in this unit drive displacement after average length.On the other hand, about the above-mentioned slave end part of slave end linkage component 54, because its length does not change, therefore coordinate the change of the above-mentioned average length of above-mentioned driving side part, the position of center of rotation 54a is differently represented.

Further, the change of the driven displacement of the above-mentioned slave end part in this Fig. 8 becomes the change of the driven displacement of the slave end linkage component 54 of the impact of the change of the above-mentioned bar ratio be subject in the linkage A of Fig. 7.Specifically, as understood from Fig. 8, in the linkage A of Fig. 7, the above-mentioned average length of the above-mentioned driving side part of driving side linkage component 53 is shorter, namely, the unit drive displacement of angle [alpha] close to 180 ° time, the driven displacement (amount of spin) of slave end linkage component 54 (above-mentioned slave end part) is less, and this driven displacement is followed successively by 13.1 °, 11.8 °, 11.4 °, 11.2 ° from the unit drive displacement of longer (angle [alpha] is close to 90 °) of the above-mentioned average length of above-mentioned driving side part.Further, the change (difference of the driven displacement of the unit drive displacement formerly in continuous print Liang Ge unit drive displacement and the driven displacement of posterior unit drive displacement) of the driven displacement of the slave end linkage component 54 (above-mentioned slave end part) in the per unit drive displacement of driving side linkage component 53 is followed successively by 1.3 °, 0.4 °, 0.2 °.

In sum, if consider the driven displacement of the slave end linkage component 54 (above-mentioned slave end part) in the linkage A of Fig. 7, then in the case of fig. 7, as mentioned above, in the per unit drive displacement of driving side linkage component 53, the driven displacement of slave end linkage component 54 diminishes gradually, and the change of its driven displacement (reduction) to diminish gradually be successively 22.6 °, 2.9 °, 1.2 °.On the other hand, the driven displacement being subject to the slave end linkage component 54 of the impact of the change of the above-mentioned bar ratio in the linkage A of Fig. 7 is described above, in the per unit drive displacement of driving side linkage component 53, diminishing gradually is successively 13.1 °, 11.8 °, 11.4 °, 11.2 °, and the change (reduction) of this driven displacement is followed successively by 1.3 °, 0.4 °, 0.2 °.

Like this, even if be subject to the impact of the change of above-mentioned bar ratio, slave end linkage component 54 changes as follows relative to the driven displacement of the unit drive displacement of driving side linkage component 53: diminish gradually in the per unit drive displacement of the driving side linkage component 53 of angle [alpha] from 90 ° and its reduction diminishes gradually.Wherein, according to the above, the reduction of this driven displacement, compared with the reduction of the driven displacement of the slave end linkage component 54 obtained in the figure 7, is less reduction.This can be understood as, and the change of the driven displacement of the slave end linkage component 54 when Fig. 7 is not only by the impact of the change of above-mentioned bar ratio.And, in linkage A, there is angle [alpha] as above-mentioned bar than change key element in addition, therefore the remainder of the change (reduction of the driven displacement of the slave end linkage component 54 obtained in the figure 7) of this driven displacement is subject to the impact of the change of angle [alpha].

By the way, the reduction being subject to the driven displacement of the slave end linkage component 54 of the impact of the change of angle [alpha] can deduct by the reduction of the driven displacement obtained from Fig. 7 the reduction being subject to the driven displacement of the impact of the change of above-mentioned bar ratio obtained in Fig. 8 and obtain.Specifically, both differences are followed successively by 21.3 °, 2.5 °, 1.0 ° from angle [alpha] close to 90 ° of sides, therefore in the linkage A of Fig. 7, due to the impact of the change of angle [alpha], with regard to the driven displacement of the slave end linkage component 54 in the constituent parts drive displacement of four the unit drive displacement relative to driving side linkage component 53 with regard to the state being 90 ° from angle [alpha], driven displacement in secondary unit drive displacement is less than the driven displacement in initial unit drive displacement 21.3 °, next coming in order be changed to little 2.5 °, 1.0 °.

Therefore, in linkage A, alternatively have following characteristic: even if except the impact of above-mentioned bar ratio, with the change of the angle [alpha] the scope of 90 ° to 180 °, the driven displacement of slave end linkage component 54 diminishes gradually in the per unit drive displacement of driving side linkage component 53.

Like this, in the linkage A of Fig. 7, the driven displacement of slave end linkage component 54 due to the impact of the change of angle [alpha], and changes in the mode of such conic section that diminishes gradually in the per unit drive displacement of driving side linkage component 53.Therefore, even if only grasp the impact produced by the change of angle [alpha], as shown in the wavy curve A of the also expression as middle in Fig. 6 (A) in scope (a3) of the amount of spin in the driven displacement of slave end linkage component 54, represent the dynamic trend (characteristic) of conic section.Namely the above-mentioned dynamic trend, in scope (a3) is carry out drive displacement with angle [alpha] from the mode of 90 ° to 180 ° changes with driving side linkage component, diminish gradually in the per unit drive displacement of driving side linkage component.

In addition, if based on above-mentioned idea, then in the wavy curve A of the graphical representation with Fig. 6 (A), about can realize beyond scope (a3) angle [alpha] of linkage A scope, namely, above-mentioned scope (a1), (a2), (a4), above-mentioned dynamic trend in (a5) and (a6) also can similarly obtain.Further, the dynamic trend as the driven displacement of the slave end linkage component of this result obtained is as described below.

About the region of the curve map between 0 ° and 90 ° of angle [alpha], angle [alpha] in scope (a1), namely, when angle [alpha] changes from 0 ° of side is more than 0 ° and angular range less than 90 °, and above-mentioned dynamic trend is contrary with the above-mentioned dynamic trend in above-mentioned scope (a3).Namely, at scope (a1), above-mentioned dynamic trend is become large conic section gradually in the per unit drive displacement of driving side linkage component.On the other hand, angle [alpha] in scope (a2), namely, when angle [alpha] changes from 90 ° of sides is the angular range of less than 90 ° more than 0 °, and above-mentioned dynamic trend is identical with the above-mentioned dynamic trend in above-mentioned scope (a3).

In addition, about the region of the curve map between 180 ° and 270 ° of angle [alpha], angle [alpha] in scope (a4), namely, when angle [alpha] changes from 180 ° of sides is the angular range of more than 180 ° less than 270 °, above-mentioned dynamic trend and the above-mentioned dynamic trend in scope (a3) contrary (identical with the above-mentioned dynamic trend in scope (a1)).

And, about the region of the curve map of angle [alpha] between 270 ° and 360 °, angle [alpha] in scope (a5), namely, when angle [alpha] changes from 270 ° of sides is more than 270 ° and the angular range of less than 360 °, and above-mentioned dynamic trend is identical with the above-mentioned dynamic trend in scope (a3).On the other hand, angle [alpha] in scope (a6), namely, when angle [alpha] changes from 360 ° of sides is the angular range of less than 360 ° more than 270 °, above-mentioned dynamic trend and the above-mentioned dynamic trend in scope (a3) contrary (identical with the above-mentioned dynamic trend in scope (a1), (a4)).

< is about linkage B >

In addition, about the above-mentioned dynamic trend of the scope of the angle [alpha] that can realize in linkage B, first, an example based on the linkage B shown in Fig. 9 is described the above-mentioned dynamic trend in above-mentioned scope (b4).Wherein, in the example in the figures, driving side linkage component 56 represents with single dotted broken line, and slave end linkage component 57 represents with double dot dash line, in addition, the rotation direction dotted arrows V ' of driving side linkage component 56 represents, and the rotation direction of slave end linkage component 57 dotted arrow W ' represents.Further, Fig. 9 represents the situation that angle [alpha] changes the scope of 180 ° to 270 °, and represents and make driving side linkage component 56 respectively rotate the state of (drive displacement) unit drive displacement amount (in illustrated example being 11.25 °).

As understood from this figure, in linkage B, when making driving side linkage component 56 carry out drive displacement with angle [alpha] in the mode that the scope of 180 ° to 270 ° changes, the dynamic trend that slave end linkage component 57 is expressed as follows relative to the driven displacement of this drive displacement: slave end linkage component 57 relative to the driven displacement of unit drive displacement amount (11.25 °) in angle [alpha] close to becoming large when 180 °, diminishing along with close to 270 °.Specifically, as illustrated, slave end linkage component 57 is 24.3 ° → 13.7 ° → 5.6 ° → 1.4 ° from angle [alpha] close to diminishing gradually successively 180 ° of sides relative to the driven displacement of the drive displacement (unit drive displacement) of the unit drive displacement amount of driving side linkage component 56.

Namely, linkage B as shown in Figure 9, angle [alpha] changes driving side linkage component 56 such the scope of 180 ° to 270 ° with the drive displacement of driving side linkage component 56 slewing area, slave end linkage component 57 has following characteristic relative to the driven displacement of the drive displacement of driving side linkage component 56: angle [alpha] is more better close to 180 ° of efficiency, along with angle [alpha] is deteriorated gradually close to 270 °.

Wherein, in linkage B, with the rotation of driving side linkage component 56, the length of the part (slave end part) of center (point of contact) 58a of the linking part 58 from center of rotation 57a to two linkage component of slave end linkage component 57 changes, the length of this slave end part changes with from the ratio of the length of the part (driving side part) of the center of rotation 56a to point of contact 58a of driving side linkage component 56 that is bar ratio, and the change of this bar ratio can impact to the driven displacement of slave end linkage component 57.

In addition, when Fig. 9 of linkage B, namely, as shown in Figure 9, about in linkage B, the situation that driving side linkage component 56 carries out drive displacement with angle [alpha] in the mode that the scope of 180 ° to 270 ° changes (is elliptically called " the linkage B of Fig. 9 " below.), the change of the driven displacement of the slave end linkage component 57 of the per unit drive displacement of the driving side linkage component 56 that the change of this bar ratio causes can be obtained based on Figure 10.

Figure 10 is the linkage B about Fig. 9, makes the turned position of the driving side linkage component 56 of constituent parts drive displacement as one man represent the driven displacement of slave end linkage component 57 relative to the unit drive displacement of driving side linkage component 56.Namely, in Fig. 10, by the drive displacement of the driving side linkage component 56 in constituent parts drive displacement with the Shape Representation making its starting position consistent.Wherein, in linkage B, as mentioned above, in constituent parts drive displacement, the length of the above-mentioned slave end part of slave end linkage component 57 changes, therefore, in Fig. 10, about the length of the above-mentioned slave end part of the slave end linkage component 57 in constituent parts drive displacement, be by the length equalization of the above-mentioned slave end part in this unit drive displacement after average length.On the other hand, because the length of the above-mentioned driving side part of driving side linkage component 56 does not change, therefore about the above-mentioned slave end part of slave end linkage component 57, coordinate the change of the above-mentioned average length of above-mentioned slave end part, the position of center of rotation 57a is differently represented.

Further, the change of the driven displacement of the above-mentioned slave end part in this Figure 10 becomes the change of the driven displacement of the slave end linkage component 57 of the impact of the change of the above-mentioned bar ratio be subject in the linkage B of Fig. 9.Specifically, as understood from Figure 10, in the linkage B of Fig. 9, the above-mentioned average length of the above-mentioned slave end part of slave end linkage component 57 is longer, namely, more when the unit drive displacement of angle [alpha] close to 270 °, the driven displacement (amount of spin) of slave end linkage component 57 (above-mentioned slave end part) is less, and this driven displacement is followed successively by 26.1 °, 20.9 °, 15.9 °, 12.5 ° from the unit drive displacement of the above-mentioned average length of above-mentioned slave end part short (angle [alpha] is close to 180 °).Further, the change of the driven displacement of the slave end linkage component 57 (above-mentioned slave end part) in the per unit drive displacement of driving side linkage component 56 is followed successively by 5.2 °, 5.0 °, 3.4 °.

In sum, if consider the driven displacement of the slave end linkage component 57 (above-mentioned slave end part) in the linkage B of Fig. 9, then when Fig. 9, as mentioned above, in the per unit drive displacement of driving side linkage component 56, the driven displacement of slave end linkage component 57 diminishes gradually, and the change of its driven displacement (reduction) to diminish gradually be successively 10.6 °, 8.1 °, 4.2 °.On the other hand, the driven displacement of the slave end linkage component 57 that the impact being subject to the change of the above-mentioned bar ratio in the linkage B of Fig. 9 causes is described above, in the per unit drive displacement of driving side linkage component 56, diminishing gradually is successively 26.1 °, 20.9 °, 15.9 °, 12.5 °, and the change (reduction) of this driven displacement is followed successively by 5.2 °, 5.0 °, 3.4 °.

Like this, even if be subject to the impact of the change of above-mentioned bar ratio, slave end linkage component 57 changes as follows relative to the driven displacement of the unit drive displacement of driving side linkage component 56: diminish gradually in the per unit drive displacement of the driving side linkage component 56 of angle [alpha] from 180 ° and reduction diminishes gradually.Wherein, can be clear and definite according to the above: the reduction of this driven displacement, compared with the reduction of the driven displacement of the slave end linkage component 57 obtained in Fig. 9, is less reduction.Be interpreted as thus, the change of the driven displacement of the slave end linkage component 57 when Fig. 9 is not only by the impact of the change of above-mentioned bar ratio.And, in linkage B, angle [alpha] is there is than change key element in addition as above-mentioned bar, therefore for the remainder of the change (reduction of the driven displacement of the slave end linkage component 57 obtained in fig .9) of this driven displacement, the impact of the change of angle [alpha] is subject to.

By the way, the reduction being subject to the driven displacement of the slave end linkage component 57 of the impact of the change of angle [alpha] can deduct by the reduction of the driven displacement obtained from Fig. 9 the reduction being subject to the driven displacement of the impact of the change of above-mentioned bar ratio obtained in Figure 10 and obtain.Specifically, both differences are followed successively by 5.4 °, 3.1 °, 0.8 ° from angle [alpha] close to 180 ° of sides, therefore in the linkage B of Fig. 9, due to the impact of the change of angle [alpha], in the driven displacement of the slave end linkage component 57 in the constituent parts drive displacement of four the unit drive displacement relative to driving side linkage component 56 from the state that angle [alpha] is 180 °, driven displacement in secondary unit drive displacement is less than the driven displacement in initial unit drive displacement 5.4 °, next coming in order be changed to little 3.1 °, 0.8 °.

Therefore, in linkage B, have following characteristic: except the impact of above-mentioned bar ratio, with the change of the angle [alpha] the scope of 180 ° to 270 °, the driven displacement of slave end linkage component 57 diminishes gradually in the per unit drive displacement of driving side linkage component 56.

Like this, in the linkage B of Fig. 9, the driven displacement of slave end linkage component 57 owing to being subject to the impact of the change of angle [alpha], and changes in the mode of such conic section that diminishes gradually in the per unit drive displacement of driving side linkage component 56.Therefore, even if the impact that the change grasping only angle [alpha] produces, the amount of spin in the driven displacement of slave end linkage component 57 also represents the dynamic trend (characteristic) of conic section as shown in the wavy curve B represented in Fig. 6 (B) in scope (b4).Namely the above-mentioned dynamic trend, in scope (b4) is carry out drive displacement with angle [alpha] from the mode of 180 ° to 270 ° changes with driving side linkage component, diminish gradually in the per unit drive displacement of driving side linkage component.

In addition, if based on above-mentioned idea, then in the wavy curve B of the graphical representation with Fig. 6 (B), about can realize beyond scope (b4) angle [alpha] of linkage B scope, namely, above-mentioned scope (b1), (b2), (b3), above-mentioned dynamic trend in (b5) and (b6) also can similarly obtain.Further, the dynamic trend as the driven displacement of the slave end linkage component of this result obtained is as described below.

About the region of the curve map between 0 ° and 90 ° of angle [alpha], angle [alpha] in scope (b1), namely, when angle [alpha] changes from 0 ° of side is the angular range of more than 0 ° less than 90 °, and above-mentioned dynamic trend is identical with the above-mentioned dynamic trend in above-mentioned scope (b4).On the other hand, angle [alpha] in scope (b2), namely, when angle [alpha] changes from 90 ° of sides is less than 90 ° and the angular range of more than 0 °, and above-mentioned dynamic trend is contrary with the above-mentioned dynamic trend in above-mentioned scope (b4).Namely, at scope (b2), above-mentioned dynamic trend is the tendency becoming large conic section in the per unit drive displacement of driving side linkage component gradually.

In addition, about the region of the curve map between 90 ° and 180 ° of angle [alpha], angle [alpha] in scope (b3), namely, when angle [alpha] changes from 90 ° of sides is the angular range of more than 90 ° less than 180 °, and above-mentioned dynamic trend is contrary with the above-mentioned dynamic trend in scope (b4), and (the above-mentioned dynamic trend in scope (b2) is identical.

And, about the region of the curve map between 270 ° and 360 ° of angle [alpha], angle [alpha] in scope (b5), namely, when angle [alpha] changes from 270 ° of sides is the angular range of more than 270 ° less than 360 °, above-mentioned dynamic trend and the above-mentioned dynamic trend in scope (b4) contrary (identical with the above-mentioned dynamic trend in scope (b2), (b3)).On the other hand, angle [alpha] in scope (b6), namely, when angle [alpha] changes from 360 ° of sides is less than 360 ° and angular range more than 270 °, and above-mentioned dynamic trend is identical with the above-mentioned dynamic trend in scope (b4).

In addition, above, about linkage A, B, to the linkage A of angle [alpha] when the angular range of 90 ° or roughly 90 ° changes, scope (scope (a1) ~ (a6) of the angle [alpha] that the structure of B can realize, (b1) ~ (b6)) in above-mentioned dynamic trend be illustrated, in above-mentioned each scope, even the angular range that angle [alpha] changes is than above-mentioned 90 ° or the scope of roughly 90 ° little, above-mentioned dynamic trend in this little scope is also the tendency identical with the above-mentioned dynamic trend of the above-mentioned scope comprising this scope.

And, as discussed above, about linkage A, B, the scope of the angle [alpha] that its above-mentioned dynamic trend can realize in its structure, becomes the tendency represented with wavy curve A, the B in the curve map of Fig. 6 (A) or Fig. 6 (B).Namely, linkage A, B have following characteristic: with the drive displacement of driving side linkage component, slave end linkage component carries out driven displacement according to this wavy curve A, B.

In sum, if consider the linkage 41 in above-mentioned the present embodiment, then linkage 41 is the linkages formed as follows, namely, as described above, coil diameter as driving side linkage component is followed bar 42 and is followed the rotation of bar 42 as the linking part 47 of the dwang 43 of slave end linkage component with coil diameter and carry out displacement to the bearing of trend that coil diameter follows bar 42 (its support portion 42a), and therefore this linkage 41 is equivalent to above-mentioned linkage A.Therefore, in linkage 41, follow the rotation (drive displacement) of bar 42 with coil diameter, dwang 43 carries out rotating (driven displacement) according to the above-mentioned dynamic trend that the wavy curve A in the curve map with Fig. 6 (A) represents.

In addition, as mentioned above, in the linkage 41 of the present embodiment, from the winding of fabric 1 at the end of winding, angle [alpha] changes at the angular range of 100 ° to 162 °.Further, this angular range is equivalent to the scope represented with (z) in above-mentioned scope (a3) in the curve map of Fig. 6 (A).Therefore, the above-mentioned dynamic trend of the dwang 43 at above-mentioned angular range in linkage 41 is the tendency identical with the above-mentioned dynamic trend of the slave end linkage component in above-mentioned scope (a3).Namely, linkage 41 plays effect as object of the present invention (hereinafter also referred to as " this effect " at above-mentioned angular range.), namely, with coil diameter follow the drive displacement of bar 42, due to the impact of the change of angle [alpha], the driven displacement of dwang 43 with follow in coil diameter the mode diminished gradually in the per unit drive displacement of bar 42 be conic section change.In other words, linkage 41 plays following effect: to start at the end of reeling during this from winding, due to the impact of the change of angle [alpha], the amount of spin of the dwang 43 that the rotation that the coil diameter that the adjoint unit coil diameter after just starting relative to reeling increases follows bar 42 obtains, the amount of spin of the dwang 43 that the rotation that the coil diameter that the adjoint unit coil diameter before winding closes to an end increases follows bar 42 obtains becomes little amount of spin.

And, in linkage 41, identical with the linkage A of Fig. 7, follow bar 42 with coil diameter and carry out drive displacement, the length that coil diameter follows the part (being equivalent to above-mentioned " driving side part ") at the center (the axle center 44a of connecting pin 44) from center of rotation (position of the axle center 45a of back shaft 45) to the linking part 47 of two linkage components of bar 42 (support portion 42a) changes in the mode shortened gradually, the length of the part (being equivalent to above-mentioned " slave end part ") from center of rotation (position of the axle center 48a of back shaft 48) to the axle center 44a of connecting pin 44 of dwang 43 changes than to become large mode gradually relative to the ratio of the length of this driving side part that is bar, therefore also due to the impact of the change of this bar ratio, the driven displacement of dwang 43 is also followed in coil diameter in the per unit drive displacement of bar 42 and is changed to occur in a diminishing manner.Namely this, above-mentioned effect also embodies due to the impact of the change of above-mentioned bar ratio.Therefore, by above-mentioned the effect that the impact of the change on angle [alpha] produces, the linkage 41 of the present embodiment adds that this effect that the impact of the change of above-mentioned bar ratio produces can obtain this larger effect with being multiplied, can realize above-mentioned effect thus.

In addition, the first embodiment is not limited to structure described above, also can implement with the form after being out of shape as following (1), (2).

(1) in the above-described first embodiment, the initial configuration of each linkage component in linkage 41 is set as, the slewing area (to start at the end of winding coil diameter during this from winding and follow the scope of bar 42 rotation) of bar 42 is followed in coil diameter, angle [alpha] meets above-mentioned condition (a) and changes at the angular range (scope (z) by the graphical representation of Fig. 6 (A)) of 100 ° to 162 °, but the initial configuration that the present invention is not limited to each linkage component is set as the situation that angle [alpha] changes at angular range as described in the first embodiment, the initial configuration of each linkage component is set as that angle [alpha] meets above-mentioned condition (a), namely, coil diameter with above-mentioned slewing area follows the rotation of bar, angle [alpha] angular range of less than 195 ° more than 90 ° becomes large direction to angle and changes.

In addition, " angular ranges of more than 90 ° less than 195 ° " in above-mentioned condition (a) are the angular ranges that scope (a3) in the curve map of Fig. 6 (A) adds the scope of 180 ° to 195 ° of the angle [alpha] in scope (a4), it is the scope exceeding the scope (a3) (more than 90 ° less than 180 °) playing this above-mentioned effect, about this angular range, specifically as described below.

In the explanation relevant to the characteristic employing the linkage of Fig. 7 in above-mentioned first embodiment, in order to the characteristic of the linkage A of every 90 ° of angle [alpha] is described, in the figure 7, the situation linkage A changed the scope of 90 ° to 180 ° as angle [alpha] represents, in this illustrated structure, linkage A is merely able to make driving side linkage component 53 with the state of angle [alpha] from 90 ° until the mode of 180 ° carries out drive displacement, can also to make driving side linkage component 53 drive displacement more than 180 ° to the mode of 270 ° of ground changes.Namely the structure that the angular range (scope (a3)+(a4)) that, it is 90 ° to 270 ° that linkage A becomes in angle [alpha] can change.

And, linkage A is so when angle [alpha] changes at scope (a3)+(a4), can be clear and definite from above-mentioned explanation, this effect is played during angle [alpha] changes in scope (a3), angle [alpha] scope (a4) change period play with this effect opposite effect, namely, the drive displacement of adjoint driving side linkage component, the driven displacement of slave end linkage component becomes large effect gradually (hereinafter also referred to " adverse effect ".)。

Wherein, about the driven displacement of the slave end linkage component in this scope (a4), the curve map observing Fig. 6 (A) is also known, at the scopes of 180 ° to+15 ° of angle [alpha] (angular range of 180 ° to 195 °: illustrated scope (p)), the change of this driven displacement is very little.Therefore, even if make the last unit drive displacement in the slewing area of driving side linkage component as angle [alpha] exceed (leap) 180 ° ground change when, if the angle [alpha] of the rotation finish time in this last unit drive displacement is less than 195 °, then the driven displacement of the slave end linkage component in the unit drive displacement that the driven displacement of the slave end linkage component in this last unit drive displacement is more previous than it is little.

Like this, in linkage A, scope (a4) is the scope playing adverse effect, if but in the scope (p) of the angle [alpha] of rotation finish time in above-mentioned last unit drive displacement in scope (a4), then there is this linkage A plays this effect situation in the slewing area of driving side linkage component.Therefore, in the present invention, can to the linkage of the bearing of trend displacement of driving side linkage component about the linking part being configured to two linkage components as linkage A, in order to play this effect, the initial configuration of each linkage component is set as that angle [alpha] meets above-mentioned condition (a).

Wherein, scope (p) in scope (a3) and scope (a4), as mentioned above, angle [alpha] is more close to 180 °, slave end linkage component is less relative to the driven displacement of the unit drive displacement of driving side linkage component, therefore reel start time, angle [alpha] is close to the state of 180 °, and available effect is less.Therefore, the initial configuration of preferred each linkage component is set as, winding start time angle [alpha] be less than 150 ° as well.

(2) in above-mentioned first embodiment and above-mentioned (1), about the initial configuration of each linkage component in linkage A, be set as that angle [alpha] meets above-mentioned condition (a), but the present invention is not limited to this, the above-mentioned initial configuration of linkage A also can be set as the slewing area of following bar in coil diameter, and angle [alpha] meets following condition (b) or condition (c).

Condition (b): the angular range being contained in more than-15 ° less than 90 °, and close to 90 ° at the end of comparing winding when winding starts.

Condition (c): be contained in more than 270 ° and the angular range of less than 375 °, and close to 270 ° at the end of comparing winding when winding starts.

About this condition (b), (c), specifically, first about condition (b), this angular range as explained above, is the angular range comprising " the rotation direction opposition side angulation of following bar in coil diameter is the angular range of 15 ° to 0 ° " and " the rotation direction side angulation of following bar in coil diameter is the angular range of 0 ° to 90 ° ".Wherein, about " the rotation direction side angulation of following bar in coil diameter is the angular range of 0 ° to 90 ° ", just because of the condition of " close to 90 ° at the end of comparing winding when winding starts ", this angular range angle [alpha] be changed to 90 ° to 0 °, correspond to the scope (a2) in the curve map of above-mentioned Fig. 6 (A) according to its angular range of its change direction (angle: large → little).In addition, about " the rotation direction opposition side angulation of following bar in coil diameter is the angular range of 15 ° to 0 ° ", in other words, this angular range is " angular range of more than 345 ° less than 360 ° of angle [alpha] ", according to above-mentioned dynamic trend, then this angular range is a part for the scope (a6) in the curve map of above-mentioned Fig. 6 (A), and is that 360 ° (=0 °) are to the angular ranges of 345 °.

Therefore, as the second embodiment of the present invention, be configured to above-mentioned linking part based on Fig. 5 (a), Fig. 5 (b), Fig. 6 (A), Fig. 6 (B), Figure 11 and Figure 12 can be described to an embodiment of the cloth winding tension regulator of the linkage of the bearing of trend displacement of dwang possessing below.In addition, in this second embodiment, the batching torque adjustment arrangement as prerequisite is the structure identical with above-mentioned first embodiment.In addition, linkage 59 in this second embodiment eliminates diagram in fig. 11, but identical with the linkage 41 of above-mentioned first embodiment, be the structure linked with the follower lever 28 in batching torque adjustment arrangement 10 via rotary transfer machine and back shaft.Further, as shown in figure 11, in this linkage 59, the structure that the linking part 62 that each linkage component (coil diameter follows bar 60 and dwang 61) becomes them directly can link with displacement to the bearing of trend of dwang 61.

It is follow the structure that bar 42 forms identically with the coil diameter in above-mentioned first embodiment that coil diameter follows bar 60, there is support portion 60a, pars intermedia 60b and abutting part 60c and these parts are formed integratedly, and there is the through hole 60d of the one end being formed at support portion 60a, and in the central authorities of the boundary member of support portion 60a and pars intermedia 60b, there is through hole 60e, at abutting part 60c, roller 46 is installed.And, coil diameter is followed bar 60 and is configured on fabric width direction between loom frame 9 and cloth beam 6, and can be supported in rotationally on loom frame 9 via back shaft 45, this back shaft 45 to be intercalated in the through hole 60d of support portion 60a and to be disposed in the top of the axle center 6a of cloth beam 6 in the vertical direction, coil diameter is followed bar 60 and is arranged to, and maintains the abutting state of roller 46 due to its deadweight relative to the fabric 1 be wound on cloth beam 6 in fell 2 side.

In addition, about the face shaping of dwang 61, identical with the dwang 43 in above-mentioned first embodiment, in addition, in its end side, be identically formed through hole 61a with dwang 43.Wherein, dwang 61 is formed in its another side and extends in their extension direction and elongated hole 61b through on thickness of slab direction.And, dwang 61 identically with above-mentioned first embodiment, fabric width direction is configured in loom frame 9 and coil diameter is followed between bar 60, and at one end side can be supported on loom frame 9 rotationally via the back shaft 63 be intercalated in through hole 61a.In addition, back shaft 63 is provided with the synchronous pulley in above-mentioned rotary transfer machine identically with the back shaft 48 of above-mentioned first embodiment.Therefore, as mentioned above, dwang 61 (having the linkage 59 of dwang 61) links with the follower lever 28 in batching torque adjustment arrangement 10 via rotary transfer machine and back shaft 63.

And coil diameter is followed bar 60 and is linked via connecting pin 64 identically with above-mentioned first embodiment with dwang 61.Wherein, in this second embodiment, be formed with elongated hole as above-mentioned in dwang 61 side, by the connecting pin 64 being fixedly installed on coil diameter and following bar 60 being inserted the elongated hole 61b of dwang 61, thus the two directly links.Specifically, connecting pin 64 is fixed on the form intercalation outstanding to loom frame 9 side the through hole 60e that coil diameter follows bar 60, and this connecting pin 64 becomes the form of the elongated hole 61b inserting dwang 61, thus coil diameter follows bar 60 and dwang 61 directly links.In addition, in such linkage 59, observe from fabric width direction, linking part 62 is that coil diameter is followed bar 60 and dwang 61 and intersected also overlapping part, and the center of this linking part 62 becomes the axle center 64a of connecting pin 64.

Further, in the linkage 59 in this second embodiment, because the structure of the rotation of bar 60 and the bearing of trend displacement to dwang 61 to be followed in the position of making linking part 62 (connecting pin 64) with coil diameter, thus the rotation of two linkage components is allowed.In addition, the development length of this elongated hole 61b allows the displacement of following the connecting pin 64 of the rotation of bar 60 from the winding adjoint coil diameter started at the end of reeling during this certainly.By the way, in linkage 59 in this second embodiment, as shown in hereinafter, as the result of setting initial configuration, the rotation of bar 60 is followed with the coil diameter in above-mentioned period, the position of connecting pin 64 on the bearing of trend of dwang 61 near the central authorities of dwang 61 towards the direction of another side (with back shaft 63 opposite side of support rotating bar 61), change in 2/5 degree of the development length of dwang 61.

Comprise above such structure linkage 59 basis second embodiment loom in, about the coil diameter of batching 1, for 300mm at the end of when winding starts being 100mm, winding.And, in this second embodiment, about the initial configuration of each linkage component in linkage 59, be set as meeting following condition (d).

Specifically, line segment N ' (shown in Figure 12 single dotted broken line) is set to by linking the line segment supporting the coil diameter back shaft 45 (its axle center 45a) and linking part 62 (its center: the axle center 64a of connecting pin 64) of following bar 60, link to support and the back shaft 63 (its axle center 63a) of dwang 61 and the line segment of linking part 62 (axle center 64a) are set to line segment K ' (double dot dash line shown in Figure 12), by line segment K ' relative to line segment N ' after the rotation direction side angulation that coil diameter follows bar 60 (line segment N ') is set to angle [alpha], the slewing area of bar 60 is followed in coil diameter, initial configuration is set as that angle [alpha] meets following condition (d).

Condition (d): the angular range being contained in more than 170 ° less than 270 °, and close to 270 ° when starting than winding at the end of winding.

Wherein, in the structure of this second embodiment, the length (distance of the axle center 63a of back shaft 63 and the axle center 64a of connecting pin 64) of line segment K ' is not fixed, but follows the rotation of bar 60 with coil diameter and change.Namely, in the linkage 59 of this second embodiment, if coil diameter is followed bar 60 and is rotated, then with this rotation, connecting pin 64 slides towards another side (upper end side in elongated hole 61b) of dwang 61 in elongated hole 61b, therefore like this as the result of the change in location of connecting pin 64, the length of line segment K ' is elongated gradually.Therefore, the length (initial configuration) when reeling beginning of line segment K ' is minimum, at the end of winding, become maximum.

Further, in this second embodiment, in order to satisfy condition (d), the initial configuration of each linkage component is set as that the angle [alpha] in initial configuration is 180 °.And, in this second embodiment, when setting the initial configuration of each linkage component, first, follow the initial configuration of bar 60 about coil diameter, with the coil diameter in above-mentioned first embodiment follow the setting of the initial configuration of bar 42 identical set.Further, be accompanied by this, determine that coil diameter follows whole amounts of spin that the arrangement angles of the support portion 60a (line segment N ') of bar 60 and coil diameter follow bar 60.

In addition, about the initial configuration of dwang 61, in this second embodiment, according to following situation and consider the design aspect in mechanical structure system limit set, namely, the arrangement angles of the support portion 60a at the end of whole amounts of spin of following bar 60 according to the arrangement angles of the support portion 60a in initial configuration and coil diameter obtain winding, always fix from the distance of the axle center 45a to the axle center 64a of connecting pin 64 of back shaft 45, and back shaft 63 angle [alpha] be arranged in initial configuration is as described above 180 ° of such positions and is arranged on based on the angle [alpha] during condition (d) is at the end of winding to be less than 270 ° such positions.Further, its result, determines the arrangement angles of the dwang 61 in the position of back shaft 63, initial configuration and whole amounts of spin of dwang 61.By the way, in this second embodiment, the angle [alpha] at the end of the position of back shaft 63 is configured in winding is the position of 245 °.

As mentioned above, in the loom of linkage 59 comprising the initial configuration being set with each linkage component, coil diameter is followed the direction that bar 60 is representing with dotted arrows X along with coil diameter increase in Figure 11 and is carried out in the process of rotating towards fell 2 side, identically with above-mentioned first embodiment, increase relative to the unit coil diameter from winding at the end of winding and always rotate with fixing amount of spin.In addition, like this, follow bar 60 rotate with coil diameter, follow the dwang 61 that bar 60 links via connecting pin 64 with coil diameter and rotate towards fell 2 side with the direction that dotted arrow Y ' represents in Figure 11.

Further, in initial configuration (when winding starts), be set as that the angle [alpha] of 180 ° becomes 245 ° as described above at the end of winding.Namely, link second back shaft (back shaft 63) of support rotating bar 61 and the line segment K ' of linking part 62 relative to the rotation direction side angulation α linking the line segment N ' supporting the first back shaft (back shaft 45) and linking part 62 that coil diameter follows bar 60 and to follow in coil diameter bar 60 and be contained in the slewing area that coil diameter follows bar 60 angular range of more than 170 ° less than 270 °, and at the end of reeling ratio reel beginning time close to 270 °.

In addition, can be clear and definite according to this structure, the linkage 59 in this second embodiment corresponds to the above-mentioned linkage B shown in Fig. 9.Therefore, in linkage 59, the dynamic trend of following the drive displacement of bar 60 as the driven displacement of the dwang 61 of slave end linkage component relative to the coil diameter as driving side linkage component becomes the dynamic trend according to the wavy curve B shown in Fig. 6 (B).And, in linkage 59, as mentioned above, the slewing area of bar 60 is followed in coil diameter, angle [alpha] changes from 180 ° to 245 °, therefore dwang 61 is according to the above-mentioned dynamic trend in the scope (b4) of the graphical representation with Fig. 6 (B), follows in the per unit drive displacement of bar 60 in coil diameter, carries out driven displacement (rotation) while its driven displacement (amount of spin) diminishes gradually.

Specifically, if the amount of spin (unit drive displacement) that when unit coil diameter recruitment being set to 50mm and starting from winding, at the end of (coil diameter 100mm) to winding, the coil diameter of (coil diameter 300mm) adjoint unit coil diameter increase during this follows bar 60 is 5.5 ° as shown in figure 12, then dwang 61 is 16 ° → 13 ° → 9 ° → 6 ° from angle [alpha] close to diminishing gradually successively 180 ° of sides relative to the amount of spin of this unit drive displacement.Namely, in this second embodiment, about the amount of spin of the dwang 61 of the adjoint unit coil diameter increase started from winding at the end of winding during this, identically with above-mentioned first embodiment, the amount of spin of the dwang 61 that the rotation that the coil diameter that the adjoint unit coil diameter after just starting relative to reeling increases follows bar 60 obtains, the amount of spin of the dwang 61 that the rotation that the coil diameter that the adjoint unit coil diameter before winding closes to an end increases follows bar 60 obtains becomes little value.

Therefore, in this second embodiment, as mentioned above, amount of spin corresponding to dwang 61 changes, diminish gradually the recruitment of the batching torque solid line H1 as shown in Fig. 5 (a), be accompanied by this, the minimizing degree of cloth winding tension when per unit coil diameter increases is roughly fixing, solid line H2 as shown in Fig. 5 (b), cloth winding tension reduces roughly pro rata with the increase of coil diameter.

In addition, the second embodiment is not limited to structure described above, can also to be deformed into the form enforcement of following (1), (2).

(1) in above-mentioned second embodiment, the initial configuration of each linkage component in linkage 59 is set as the slewing area of following bar 60 in coil diameter, satisfy condition (d) as angle [alpha] and change at the angular range of 180 ° to 245 °, but the initial configuration that the present invention is not limited to each linkage component is set as the situation that angle [alpha] changes at the angular range that above-mentioned second embodiment is such, also can be that the initial configuration of each linkage component is set as that angle [alpha] satisfies condition (d), namely, coil diameter with above-mentioned slewing area follows the rotation of bar, it is just passable in angle [alpha] to be that the angular range of more than 170 ° less than 270 ° becomes the change of large direction to angle.

In addition, " angular ranges of more than 170 ° less than 270 ° " in condition (d) are the angular ranges scope of 170 ° to 180 ° of the angle [alpha] in the scope (b3) of the graphical representation with Fig. 6 (B) being added scope (b4), larger than the above-mentioned scope (b4) (more than 180 ° less than 270 °) playing this effect, about this angular range, specifically as described below.

First, the linkage B shown in Fig. 9 is identical with above-mentioned linkage A, is the structure that the angular range (scope (b3)+(b4)) that can be 90 ° to 270 ° in angle [alpha] changes.And, in linkage B, when angle [alpha] so changes at scope (b3)+(b4), can be clear and definite from above-mentioned explanation: during angle [alpha] changes in scope (b3), play adverse effect, during angle [alpha] changes in scope (b4), play this effect.

Wherein, about the driven displacement of the slave end linkage component in this scope (b3), the curve map observing Fig. 6 (B) is known, the angular ranges of 170 ° to 180 ° of angle [alpha] (illustrated scope (q)), the angular range of 180 ° to 190 ° in its driven displacement and scope (b4) is equal, becomes very large displacement.Therefore, if make the initial unit drive displacement in the slewing area of driving side linkage component be that angle [alpha] exceedes the situation of the unit drive displacement that (leap) 180 ° of ground change such and the angle [alpha] of the rotation start time in this initial unit drive displacement is more than 170 °, then the driven displacement of the slave end linkage component in this initial unit drive displacement is larger than the driven displacement of the slave end linkage component in the unit drive displacement of its next time.

Like this, in linkage B, scope (b3) is the scope playing adverse effect, if but in the scope (q) of the angle [alpha] of rotation start time in above-mentioned initial unit drive displacement in scope (b3), then exist this linkage B driving side linkage component slewing area play the situation of this effect.Therefore, in the present invention, can to the linkage of the bearing of trend displacement of slave end linkage component about the linking part being configured to two linkage components as linkage B, in order to play this effect, the initial configuration of each linkage component is set as that angle [alpha] satisfies condition (d).

(2) in above-mentioned second embodiment and above-mentioned (1), about the initial configuration of each linkage component in linkage B, be set as that angle [alpha] satisfies condition (d), but the present invention is not limited to this, the above-mentioned initial configuration of linkage B also can be set as, follow the slewing area of bar in coil diameter, angle [alpha] meets following condition (e) or condition (f).

Condition (e): be contained in more than 270 ° and the angular range of less than 370 °, close to 270 ° when starting than winding at the end of winding.

Condition (f): the angular range being contained in more than-10 ° less than 90 °, close to 90 ° when starting than winding at the end of winding.

About this condition (e), (f), specifically, first, about condition (e), above-mentioned illustrated such, this angular range is the angular range comprising " angle to 360 of angle [alpha] more than 270 ° ° angular range " and " angle [alpha] is from 0 ° (360 °) to the angular range of 10 ° (370 °) ".And, about these two angular ranges, according to the change direction (angle: large → little) of the angle [alpha] based on " close to 270 ° when starting than winding at the end of winding ", then can say that the former corresponds to scope (b6) in the curve map of above-mentioned Fig. 6 (B) (less than 360 ° and more than 270 °), the latter corresponds to the angular range of a part (less than 10 ° more than 0 °) for the scope (b2) in this curve map.

Therefore, condition (e) also comprises the condition with following situation, namely, in the angular range that an above-mentioned part for the scope (b2) playing adverse effect adds the scope (b6) playing this effect, angle [alpha] is to the direction change diminished, and angle [alpha] when winding starts is larger in the scope (playing the scope (b2) of adverse effect) of 370 ° (angles from 360 ° (0 °)+10 °) than 360 °.In addition, about " angular ranges more than 10 ° (370 °) 0 ° below (360 °) " wherein, identical with the angular range of 170 ° to 180 ° of the condition (d) illustrated in above-mentioned (1), it is the very large scope of driven displacement of slave end linkage component, therefore identical with condition (d), even the part playing the scope of adverse effect is also contained in condition (e).Further, even if when the initial configuration of each linkage component is set as meeting this condition (e), linkage B also can play this effect in the slewing area of driving side linkage component.

In addition, about condition (f), as explained above, this angular range is the angular range comprising " the rotation direction opposition side angulation of following bar in coil diameter is the angular range of 10 ° to 0 ° " and " the rotation direction side angulation of following bar in coil diameter is the angular range of 0 ° to 90 ° ".In addition, in other words the former angular range is wherein " angular range of more than 350 ° less than 360 ° of angle [alpha] " or " angular range of more than-10 ° less than 0 ° of angle [alpha] ".And, about above-mentioned two angular ranges, according to the change direction (angle: little → large) of the angle [alpha] based on " close to 90 ° when starting than winding at the end of winding ", can say that the former corresponds to a part (more than 350 ° less than 360 °) for the scope (b5) in the curve map of above-mentioned Fig. 6 (B), the latter corresponds to the scope (b1) (more than 0 ° less than 90 °) in this curve map.

Therefore, condition (f) also comprises following situation for condition, namely, in the angular range that an above-mentioned part for the scope (b5) playing adverse effect adds the scope (b1) playing this effect, angle [alpha] is to becoming the change of large direction, and angle [alpha] when winding starts is less than 0 ° and in the scope (playing the scope (b5) of adverse effect) of 350 ° (from 360 ° (0 °) to the angle of-10 °).In addition, about " more than 350 ° (-10 °) 360 ° of (0 °) angular ranges below " wherein, identical with the angular range of 170 ° to 180 ° of the condition (d) illustrated in above-mentioned (1), it is the very large scope of driven displacement of slave end linkage component, identical with condition (d), even the part playing the scope of adverse effect is also contained in condition (f).Further, when the initial configuration of each linkage component is set as meeting this condition (f), linkage B also can play this effect in the slewing area of driving side linkage component.

Such as, also can be configured to, follow the configuration (support coil diameter and follow the setting relative to the abutted position of batching of the position of the back shaft of bar and roller) of bar according to coil diameter, the amount of spin that the coil diameter that per unit coil diameter increases follows bar diminishes gradually along with the increase of coil diameter.Specifically, as mentioned above, angle γ (link support coil diameter follow the axle center of the back shaft of bar and the axle center of roller line segment, follow the rotation direction opposition side angulation of bar in coil diameter with the line segment linking the axle center of cloth beam and the axle center of roller) be that bar to bring impact angle relative to the amount of spin of unit coil diameter recruitment is followed on coil diameter.And, set in the mode become close to the angle of 180 ° of this angle γ in initial configuration and support coil diameter and follow the position of the back shaft of bar and the roller abutted position relative to batching, thus the amount of spin that the coil diameter that can realize when per unit coil diameter increases follows bar diminishes gradually along with the increase of coil diameter, such coil diameter follows the rotation of bar.Further, in this situation, utilize the collaborative effect of the effect obtained with structure of the present invention (linkage), can this larger effect be obtained.

In addition, the configuration of bar is followed according to coil diameter, contrary to the above, when the amount of spin that the coil diameter that per unit coil diameter increases follows bar to become large situation gradually or starts the increase of the coil diameter of the unit coil diameter amount setting more than three at the end of reeling according to the size of unit coil diameter recruitment from winding along with the increase of coil diameter, also exist compare just start to reel after and winding close to an end before coil diameter follow the amount of spin of bar relative to unit coil diameter recruitment, middle coil diameter follows the bar situation etc. large relative to the rotation quantitative change of unit coil diameter recruitment.But, even if in these cases, if utilize the relation of the effect obtained with structure of the present invention (linkage), the rotation of dwang is the effect playing this effect as a result, then coil diameter follows the configuration of bar also can be configuration as described above.

In addition, the present invention is not limited to embodiment described above, only otherwise depart from purport of the present invention, then can carry out various change.
